The chambers of the first gas collecting member and the second gas collecting member can be provided with combustible elements, and the oxygen index of the combustible elements is more than 21%. The oxygen index is the minimum oxygen concentration required for the material to undergo flaming combustion in a nitrogen-oxygen mixture gas stream under specified conditions. In natural air, for example, in the first chamber, the volume percentage of oxygen is slightly less than 21%, and a combustible piece made of a material with an oxygen index of more than 21% cannot perform flame combustion in natural air but can perform flameless combustion. And the second chamber has an oxygen concentration greater than 21% after being fed with the high concentration of oxygen produced by the oxygen production device, and the combustible element made of a material having an oxygen index greater than 21% is capable of undergoing flamed combustion in such an environment. Through such mode of setting, when carrying out the oxygen boosting function show, oxygen concentration in the first cavity is about 21%, the combustible element that will be in flameless combustion state is put into the first cavity, the combustion state of combustible element still is flameless combustion state, the high concentration oxygen that oxygenerator produced makes the oxygen concentration in the second cavity be greater than 21% after entering into the second cavity, under this oxygen concentration, the combustible element that will be in flameless combustion state is put into the second cavity, the combustible element just can become flameless combustion by flameless combustion state, thereby just also can prove that oxygenerator can produce the oxygen of high concentration really, improve the oxygen concentration in the second cavity.

The function display method comprises the following steps: whether a human body enters a preset range of the air conditioner or not is detected through the human body detection module, and if the human body enters the preset range, the reminding module is controlled to send a prompt of 'starting oxygen enrichment function display'. And, in a state in which the combustible element is in flameless combustion, performing the following operations: controlling at least the part of the combustible element in flameless combustion to be located in the first chamber; at least the part of the combustible element which is controlled to be in flameless combustion is positioned in the second chamber; and when, before or after the part of the combustible piece which is at least controlled to be in flameless combustion is positioned in the second chamber, the oxygen generation device is controlled to be started, and the reminding module is controlled to send out the prompt of starting oxygen enrichment.

Through such control mode, when detecting that there is the human body to enter into the preset range of air conditioner, show that someone is coming before the air conditioner, and be interested in this air conditioner, then control the suggestion that reminds the module and send "open oxygen boosting function show" this moment, remind the show that can carry out the oxygen boosting function. After the prompt is sent out, the oxygen enrichment function of the air conditioner is displayed through the display device. When the oxygen enrichment function is displayed, the part of the combustible piece which is in flameless combustion can be controlled to be positioned in the first cavity and the second cavity, the oxygen generation device is controlled to be started while, before or after the part of the combustible piece which is in flameless combustion is controlled to be positioned in the second cavity, the second cavity can be filled with high-concentration oxygen generated by the oxygen generation device, so that when the part of the combustible piece which is in flameless combustion is positioned in the first cavity, the combustion state of the combustible piece is still in the flameless combustion state, and when the part of the combustible piece which is in flameless combustion is positioned in the second cavity, the combustion state of the combustible piece can be converted from the flameless combustion state into the flame combustion state, thereby being capable of showing that the oxygen generation device really generates high-concentration oxygen and leads the high-concentration oxygen into the second cavity, improving the oxygen concentration in the second cavity, and enabling a user to visually know the oxygen enrichment function of the air conditioner, the reliability of the oxygen enrichment function of the air conditioner is improved.

Preferably, the first gas collecting component and/or the second gas collecting component are/is a conical bottle, and the first gas collecting component and/or the second gas collecting component are/is convenient and easy to obtain. The combustible element can be inserted into the opening of the conical flask, and the gas in the first gas collecting member and the second gas collecting member can be discharged out of the opening of the conical flask. When the oxygen enrichment function is displayed, the combustion state of the combustible element in the first cavity or the second cavity can be visually seen, and the whole display process is clear.

Further, when at least the part of the combustible element which is controlled to be in flameless combustion is positioned in the first cavity, the oxygen content in the gas in the first cavity is the same as that of air, the combustion state of the combustible element is still in a flameless combustion state at about 21%, and the first brightness in the first cavity is detected through the brightness detection module. When the part that is in flameless burning at least control combustible component is located the second cavity, at this moment, when oxygenerator opened first predetermined duration, oxygenerator generated oxygen entered into the second cavity that is linked together with it for the oxygen concentration in the second cavity risees to more than 21%, and the combustion state of combustible component changes into the burning of flame, detects the second luminance in the second cavity through the luminance detection module. And comparing the first brightness with the second brightness to obtain a first comparison result that the first brightness is smaller than the second brightness. The first brightness, the second brightness and the first comparison result are transmitted to the display module, the first brightness, the second brightness and the first comparison result are displayed to a user through the display module, the user can directly determine that the combustible element is in different combustion states in the first cavity and the second cavity respectively according to the first brightness, the second brightness or the first comparison result, and therefore when the oxygen generation device is started, high-purity oxygen can be introduced into the second cavity actually, the oxygen concentration in the second cavity is improved, and the reliability of the oxygen enrichment function of the air conditioner is improved.

Further, after at least the part of the combustible element in flameless combustion is controlled to be located in the second chamber, the oxygen generation device is controlled to be started for the first preset time length and then is controlled to be closed for the second preset time length, at the moment, the oxygen concentration in the chamber is reduced to about 21%, the combustion state of the combustible element is flameless combustion, and the third brightness in the chamber is detected through the brightness detection module. And comparing the second brightness with the third brightness to obtain a second comparison result that the second brightness is greater than the third brightness. The second brightness, the third brightness and the second comparison result are transmitted to the display module, the third brightness and the second comparison result are displayed for a user through the display module, the user can see according to the second brightness, the third brightness or the second comparison result that the combustion state of the combustible element when the oxygen generating device is started is obviously different from the combustion state of the combustible element after the oxygen generating device is started for the first preset time length and then is closed for the second preset time length, according to the difference of the combustion states, high-purity oxygen can be effectively proved to be introduced into the second chamber when the oxygen generating device is started, the oxygen concentration in the second chamber is improved, after the oxygen generating device is closed for the second preset time length, the oxygen concentration in the second chamber is reduced to be approximately the same as that of common air, and therefore the reliability of the oxygen enrichment function of the air conditioner is improved.

Further, at least the part of the combustible element which is controlled to be in flameless combustion is positioned in the second chamber, and the oxygen generation device is controlled to be opened for a first preset time length and then closed for a third preset time length, wherein the third preset time length is less than the second preset time length. The oxygen concentration in the cavity is gradually reduced, but still higher than 21%, the combustion state of the combustible element is in flame combustion, and the fourth brightness in the cavity is detected through the brightness detection module. And comparing the second brightness with the fourth brightness, and the third brightness with the fourth brightness to obtain a third comparison result that the second brightness is greater than the fourth brightness, and the third brightness is less than the fourth brightness. The fourth brightness and the third comparison result are transmitted to the display module, the second brightness, the third brightness, the fourth brightness and the second comparison result are displayed for a user through the display module, the user can see that the second brightness generated by combustion of the combustible piece after the oxygen generating device is started is the largest according to the second brightness, the fourth brightness generated by combustion in the third preset time period when the oxygen generating device is closed is larger than the third brightness generated by combustion after the oxygen generating device is closed for the second preset time period, so that the high-purity oxygen can be introduced into the second cavity really when the oxygen generating device is opened, the oxygen concentration in the second cavity is further improved, and the reliability of the oxygen enrichment function of the air conditioner is increased.

Further, when the human body detection module detects whether a human body enters the preset range of the air conditioner, the human body detection module firstly determines that the human body enters the preset range, then the stay time of the human body in the preset range is acquired, if the stay time of the human body in the preset range is greater than or equal to the fourth preset time, the fact that the human body stays in front of the air conditioner for a long enough time is explained, then the fact that the human body enters the preset range of the air conditioner can be judged, the human body is interested in the air conditioner, therefore, the reminding module can be controlled to send out a prompt of 'starting oxygen enrichment function display', the oxygen enrichment function display can be carried out for a user in time under the prompt, and the user can better know the oxygen enrichment function of the air conditioner.

Further, when the oxygen enrichment function is displayed, if the combustible element is in an extinguishing state, the combustible element needs to be ignited first, and preparation for displaying the oxygen enrichment function is made. The display device also comprises an ignition device, and after the fact that a human body enters a preset range is detected, the human body is interested in the air conditioner, and the oxygen enrichment function of the air conditioner can be displayed for the air conditioner. The step of "igniting the combustible element" further comprises: and controlling the ignition device to ignite the combustible element. By the control mode, after people are determined to be interested in the air conditioner, the ignition device is controlled to ignite the combustible element, and the display of the oxygen enrichment function is ready.

Further, the display device further comprises a first mechanical arm, the ignition device is clamped on the first mechanical arm, and before the step of controlling the ignition device to ignite the combustible element, the function display method further comprises the following steps: the ignition device is moved to the combustible element by a first robotic arm. By such a control mode, after the combustible element is determined to need to be ignited, the ignition device is moved to the position where the combustible element is located through the first mechanical arm, so that the combustible element can be ignited better.

Further, the step of controlling at least a portion of the combustible element in the flameless combustion state to be located in the first chamber further comprises: the portion of the combustible element in the flameless combustion state is inserted into the first chamber by a second mechanical arm. The step of controlling at least the portion of the combustible element in the flameless combustion state to be located within the second chamber further comprises: the portion of the combustible element in the flameless combustion state is inserted into the second chamber by a second mechanical arm. Through such control mode, when carrying out the oxygen boosting function show, can insert first cavity and second cavity respectively with combustible piece through the second arm in, then compare this combustible piece combustion state in first cavity and second cavity, can be that the combustible piece is flameless burning in first cavity, for the flame burning in the second cavity to just also can prove that oxygenerator opens the back and has introduced oxygen for the cavity really, improved the oxygen boosting function's of air conditioner credibility.

When the air conditioner with the oxygen enrichment function is sold, a salesperson usually faces a problem that the oxygen enrichment function of the air conditioner cannot be intuitively displayed to a consumer, which may cause low credibility of the oxygen enrichment function and is not beneficial to the sale of products. Therefore, the invention provides a function display method of an air conditioner, which is characterized in that whether a human body enters a preset range of the air conditioner is detected through a human body detection module, if the human body enters the preset range, the human body is shown to be possibly interested in the air conditioner, and at the moment, a reminding module is controlled to send out a prompt of starting oxygen enrichment function display to remind that the oxygen enrichment function display can be carried out. After the prompt is heard, the display device can be used for displaying the oxygen enrichment function of the air conditioner for the user.

In this embodiment, the air conditioner is provided with the oxygenerator and can demonstrate the display device of the oxygen boosting function of air conditioner, and wherein, the oxygenerator is used for coming out the oxygen separation in the air, obtains the oxygen of high concentration.

In step S10, the human body detection module, which may be an infrared detection module, is used to detect whether a user enters a preset range, and the infrared detection module can accurately detect whether the user enters the preset range. It should be noted that the technical means for detecting whether there is a user in the preset range by using the infrared detection module belongs to the conventional technical means in the field, and is not described herein again.

Of course, the human body detection module of the present invention may also be a radar detection module, and any specific detection method should not limit the present invention no matter what way is adopted to detect whether a user enters a preset range.

It should be noted that the human body detection module may perform real-time detection or detect according to a preset time interval, where the preset time interval may be 15 seconds, 30 seconds, 1min, 3min, and the like. Of course, these preset time intervals are only described by way of example, and are not limited thereto, and those skilled in the art can flexibly select the preset time intervals in practical applications, and in any case, the preset time intervals are adjusted and set, as long as whether a user enters the preset range can be accurately detected.

It should be noted that the preset range may be a detection range of the human body detection module during normal operation, or may be a range preset by a person skilled in the art according to experiments or experience. The preset range may be a range having a certain linear distance from the air conditioner, such as 0.8m, 1.2m, or 1.5m, and the preset range may be flexibly adjusted and set by a person skilled in the art.

Obviously, the human body detection module may be disposed on the air conditioner, or may be disposed on the display device, or on a remote controller, a mobile phone, a tablet computer, and other mobile terminals communicating with the air conditioner.

Step S20: if the human body enters the preset range, the reminding module is controlled to send out a prompt of starting oxygen enrichment function display.

In this implementation, the air conditioner is configured with a reminder module.

In step S20, based on the detection result in step S10, if it is detected that a human body enters the preset range, indicating that a person comes in front of the air conditioner and is interested in the air conditioner, at this time, the reminding module is controlled to send out a prompt of "turning on the oxygen enrichment function display". The reminding module can be a voice reminding module, after detecting that a human body enters a preset range, the reminding module sends out a reminding sound of 'opening the oxygen enrichment function display', after hearing a prompt, a user is determined to stand in front of the air conditioner, and therefore the user can be displayed in time, and the oxygen enrichment function of the air conditioner is displayed through the display device. Of course, after the reminding module gives out the prompt, the air conditioner automatic control display device can be used for displaying.

Of course, the reminding module can also be a text reminding module, namely, the salesperson and the user are reminded by sending a text reminding mode, or the voice and text reminding module is reminded of the salesperson and the user by a voice and text mode.

It should be noted that the reminding module may be disposed on the air conditioner, or disposed on the display device, or on a remote controller, a mobile phone, a tablet computer, or other mobile terminal in communication with the air conditioner.

In a possible embodiment, in the state in which the combustible element is in flameless combustion, the following operations are carried out: controlling at least the part of the combustible element in flameless combustion to be located in the first chamber; at least the part of the combustible element which is controlled to be in flameless combustion is positioned in the second chamber; and when, before or after the part of the combustible piece which is at least controlled to be in flameless combustion is positioned in the second chamber, the oxygen generation device is controlled to be started, and the reminding module is controlled to send out the prompt of starting oxygen enrichment. When the oxygen enrichment function is displayed, the reliability of the oxygen enrichment function can be proved through the difference of the combustion states of the combustible element in the first chamber and the second chamber. By such a control, when the oxygen enrichment function is exhibited, the part of the combustible element which is in flameless combustion can be located in the first chamber first, and then the part of the combustible element which is in flameless combustion can be located in the second chamber. It is also possible to first locate the part of the combustible element that is in flameless combustion in the second chamber and then locate the part of the combustible element that is in flameless combustion in the first chamber. When the part that combustible element is in flameless burning is located the second chamber, control oxygenerator opens, and the oxygen that oxygenerator produced enters into after the second chamber, improves the oxygen concentration in the second chamber for the oxygen concentration in the second chamber is greater than 21%. Therefore, when the part of the combustible piece in flameless combustion is positioned in the first chamber, the combustion state of the combustible piece is kept unchanged and still in the flameless combustion state, and when the part of the combustible piece in flameless combustion is positioned in the second chamber, the combustion state of the combustible piece is changed from flameless combustion to flame combustion, so that the oxygen generation device can be proved to generate high-concentration oxygen and introduce the high-concentration oxygen into the second chamber according to the difference of the combustion states of the combustible piece in the two chambers, the oxygen concentration in the second chamber is improved, a user can visually know the oxygen enrichment function of the air conditioner, and the reliability of the oxygen enrichment function of the air conditioner is improved. Obviously, the whole combustible element can be located in the first chamber or the second chamber, and the skilled person can flexibly select the combustible element according to the specific application scenario.

Obviously, also can be before or after the part that at least control combustible component is in flameless burning is located the second cavity, control the oxygenerator and open again to control and remind the module to send the suggestion of "opening the oxygen boosting", the concrete opportunity that the field of technical staff can select the control oxygenerator to open in a flexible way, as long as can make the combustible component that is located the second cavity turn into flame burning by flameless burning after the oxygenerator opens, and then prove that the oxygenerator can produce the oxygen of high concentration really.

It should be noted that the combustible component may also be two, such as two natural fragrances, and when performing the oxygen enrichment function display, both the two natural fragrances are ignited, and then the portions of the two natural fragrances which are in flameless combustion are respectively inserted into the first chamber and the second chamber.

In the following, a possible implementation manner of the function display method of the present invention is described with reference to fig. 3 to 6 by taking an example that a part of a combustible element in flameless combustion is controlled to be located in a first chamber, a part of the same combustible element in flameless combustion is controlled to be located in a second chamber, and a part of the same combustible element in flameless combustion is controlled to be located in the second chamber while an oxygen generation device is controlled to be opened. Fig. 3 is a flowchart of detecting whether a human body enters a preset range through a human body detection module according to an embodiment of the present invention, fig. 4 is a flowchart of comparing brightness of a combustible element in a first chamber and a second chamber in two situations where an oxygen generation device is turned on according to an embodiment of the present invention, fig. 5 is a flowchart of comparing brightness of a combustible element in a second chamber in two situations where the oxygen generation device is turned on and the oxygen generation device is turned on for a first preset time period and then turned off for a second preset time period, and fig. 6 is a flowchart of comparing brightness of a combustible element in a second chamber in three situations where the oxygen generation device is turned on, the oxygen generation device is turned on for the first preset time period and then turned off for the second preset time period, and the oxygen generation device is turned on for the first preset time period and then turned off for the third preset time period.

As shown in fig. 3, in a possible embodiment, the step S10 of detecting whether a human body is within a preset range of the air conditioner by the human body detection module further includes:

step S101: acquiring the stay time of a human body in a preset range;

step S102: and if the stay time is more than or equal to the fourth preset time, judging that someone enters the preset range.

In step S101, the human body detection modules such as the infrared detection module and the radar detection module are used to obtain the staying time of the human body in the preset range of the air conditioner. Taking the human body detection module as an infrared detection module as an example, the duration of shielding infrared rays emitted by the infrared detection module is counted, and then the stay duration of the human body in the preset range is determined.

In step S102, based on the staying time of the human body detected in step S101 within the preset range, the staying time is compared with a fourth preset time. If the staying time is longer than or equal to a fourth preset time, if the staying time is 40 seconds, the fourth preset time is 20 seconds, and the fact that the human body stays in front of the air conditioner for a long enough time is indicated, it can be judged that the human body enters a preset range of the air conditioner, and the human body is interested in the air conditioner, so that the reminding module can be controlled to send a prompt of starting oxygen enrichment function display, and a salesman can timely display the oxygen enrichment function for a user under the prompt, so that the user can better know the oxygen enrichment function of the air conditioner.

If the staying time is less than a fourth preset time, if the staying time is 10 seconds and the fourth preset time is 20 seconds, it indicates that the human body may only pass through the air conditioner and is not interested in the air conditioner, and at this time, no action is performed.

It should be noted that the specific value of the fourth preset time period is only an exemplary description, and obviously, the fourth preset time period may also be other values such as 15 seconds, 25 seconds, 30 seconds, and the like, and those skilled in the art may flexibly select the value according to a specific application scenario.

As shown in fig. 4, in a possible implementation, the function display method of the present invention further includes:

step S41: when the part of the combustible element which is controlled to be in flameless combustion is positioned in the first cavity, detecting first brightness in the first cavity through a brightness detection module;

step S42: when the part of the combustible piece in flameless combustion is controlled to be positioned in the second chamber and the oxygen generation device is controlled to be started for a first preset time length, detecting second brightness in the second chamber through the brightness detection module;

step S43: comparing the first brightness with the second brightness to obtain a first comparison result;

step S44: transmitting the first brightness, the second brightness and the first comparison result to a display module;

step S45: and displaying the first brightness, the second brightness and the first comparison result through the display module.

In this embodiment, the display device includes a brightness detection module, and this brightness detection module sets up in the cavity of gas collection component, can detect the indoor luminance of cavity in real time through this brightness detection module.

It should be noted that the brightness detection module may be a brightness detector, which is based on the photoelectric conversion principle and uses a high-precision silicon photocell as a sensing element, and an optical signal reaches the sensing element through an optical filter and is converted into an electrical signal, and then the electrical signal is processed by an integrated circuit to output a continuous linear proportional signal, i.e., a brightness value.

Obviously, the brightness detection module may also be a photodiode, and when no light is emitted, the resistance is infinite, and when light is emitted, the resistance may be as small as several hundred ohms, so that the current brightness can be determined according to the resistance value of the photodiode. Of course, the brightness detection module may be arranged in other manners as long as the brightness in the chamber can be detected in real time.

In step S41, the part of the combustible element in flameless combustion is located in the first chamber, the oxygen content in the gas in the first chamber is the same as that of air, and the combustion state of the combustible element is still in a flameless combustion state at about 21%, and at this time, the brightness in the first chamber is detected to be the first brightness by the brightness detection module such as the brightness detector.

In step S42, the part of the combustible element that is in flameless combustion is located in the second chamber, and the oxygen generator is controlled to be turned on, so that oxygen generated by the oxygen generator enters the second chamber that is communicated with the oxygen generator, when the oxygen generator is turned on for a first preset time, the oxygen concentration in the second chamber is increased to more than 21%, the combustion state of the combustible element is changed to a flamed combustion state, and at this time, the brightness in the second chamber is detected to be a second brightness by the brightness detection modules such as the brightness detector.

In step S43, the first luminance and the second luminance obtained in steps S41 and S42 are compared, e.g., the first luminance is 30cd/m²The second luminance is 350cd/m². Wherein, cd/m²(candela/square meter) is a unit of luminance, i.e., a light emission luminance per unit projected area. Based on this, the first comparison that the first luminance is smaller than the second luminance can be obtainedAnd (6) obtaining the result.

In this embodiment, the display device further includes a display module, and the display module may be a display screen, a tablet computer, or other terminals communicating with the display device, or may be a display screen disposed on the display device. The display device includes an image acquisition module, which may be but is not limited to a camera, etc., and those skilled in the art can flexibly select.

In step S44, the first brightness, the second brightness and the first comparison result obtained in step S41, step S42 and step S43 are transmitted to a display module such as a mobile terminal or a display screen.

In step S45, the display module displays the first brightness, the second brightness and the first comparison result after receiving the first brightness, the second brightness and the first comparison result uploaded in step S44.

In this way, the user can more intuitively know that the oxygen concentration in the first chamber not connected to the oxygen generator is about 21% and that the combustible element is in a flameless combustion state at the oxygen concentration. After the oxygen generating device is opened, the oxygen concentration in the second chamber connected with the oxygen generating device is increased to more than 21%, and the combustible element is in a flame combustion state under the oxygen concentration. This means that when the oxygen generator is turned on, high-purity oxygen is introduced into the second chamber, and the oxygen concentration in the second chamber is increased to more than 21%, so that the reliability of the oxygen-enriched function of the air conditioner is increased, and the product sale is facilitated.

As shown in fig. 5, in a possible implementation, the function display method of the present invention further includes:

step S42: after the part of the combustible piece in flameless combustion is controlled to be positioned in the second chamber and the oxygen generation device is controlled to be started, detecting second brightness in the second chamber through the brightness detection module;

step S51: after the part of the combustible piece in flameless combustion is controlled to be located in the second chamber, the oxygen generation device is controlled to be started for the first preset time length and then is closed for the second preset time length, the third brightness in the second chamber is detected through the brightness detection module;

step S52: comparing the second brightness with the third brightness to obtain a second comparison result;

step S53: transmitting the third brightness and the second comparison result to the display module;

step S54: and displaying the second brightness, the third brightness and the second comparison result through the display module.

In step S51, after the oxygen generator is controlled to be turned on for a first preset time period, if the first preset time period is 1min, the oxygen concentration in the chamber is greater than 21%, and then the oxygen generator is controlled to be turned off for a second preset time period, if the second preset time period is 1min, at this time, the oxygen concentration in the second chamber is gradually reduced to about 21%, at this time, the combustion state of the combustible element is flameless combustion, and the third brightness in the chamber is detected by the brightness detection module.

In step S52, the second luminance detected in step S42 is compared with the third luminance detected in step S51, such as the third luminance is 50cd/m²The second luminance is 350cd/m². Based on this, the first comparison result in which the second luminance is larger than the third luminance can be obtained.

In step S53, the second brightness, the third brightness and the second comparison result obtained in step S42, step S51 and step S52 are transmitted to a display module such as a mobile terminal or a display screen.

In step S54, the display module displays the second brightness, the third brightness and the second comparison result after receiving the second brightness, the third brightness and the second comparison result in step S53.

Therefore, a user can easily know according to the second brightness, the third brightness and the second comparison result, after the oxygen production device is started, the oxygen concentration in the second cavity can be higher than 21%, so that the combustion state of the combustible piece is a flame combustion state, after the oxygen production device is started for a first preset time and then is closed for a second preset time, the oxygen concentration in the second cavity is reduced to about 21%, and the combustion state of the combustible piece is a flameless combustion state. According to the difference of combustion state like this, just also can prove for the high-purity oxygen has been introduced in the second chamber when oxygenerator opens, improved the oxygen concentration in the second chamber, after oxygenerator closed the second and predetermine for a long time, the oxygen concentration in the second chamber drops to approximately the same with ordinary air to increase the oxygen boosting function's of air conditioner credibility.

As shown in fig. 6, in a possible implementation, the function display method of the present invention further includes:

step S42: after the part of the combustible piece in flameless combustion is controlled to be positioned in the second chamber and the oxygen generation device is controlled to be started, detecting second brightness in the second chamber through the brightness detection module;

step S51: after the part of the combustible piece in flameless combustion is controlled to be located in the second chamber, the oxygen generation device is controlled to be started for the first preset time length and then is closed for the second preset time length, the third brightness in the second chamber is detected through the brightness detection module;

step S61: after the part of the combustible piece in flameless combustion is controlled to be positioned in the second chamber, and the oxygen generation device is controlled to be started for a first preset time length and then is closed for a third preset time length, detecting fourth brightness in the second chamber through the brightness detection module;

step S62: comparing the second brightness with the fourth brightness, and the third brightness with the fourth brightness to obtain a third comparison result;

step S53: transmitting the fourth brightness and the third comparison result to the display module;

step S54: and displaying the second brightness, the third brightness, the fourth brightness and the third comparison result through the display module.

In step S61, after the oxygen generator is controlled to be turned on for a first preset time period, if the first preset time period is 1min, the oxygen concentration in the chamber is greater than 21%, and then the oxygen generator is controlled to be turned off for a third preset time period, if the second preset time period is 5 seconds, at this time, the oxygen concentration in the second chamber is still higher than 21% although it is reduced, at this time, the combustion state of the combustible element is flaming combustion, and the fourth brightness in the chamber is detected by the brightness detection module.

In step S62, the second luminance detected in step S42 is compared with the fourth luminance detected in step S61, such as the fourth luminance is 150cd/m²The second luminance is 350cd/m². The fourth luminance detected in the above step S61 is compared with the third luminance detected in the step S51, e.g., the third luminance is 50cd/m²And the fourth luminance is 150cd/m². Based on this, a third comparison result in which the second luminance is greater than the fourth luminance and the third luminance is less than the fourth luminance can be obtained.

In step S63, the second brightness, the third brightness, the fourth brightness and the third comparison result obtained in steps S42, S51, S61 and S62 are transmitted to a display module such as a mobile terminal or a display screen.

In step S64, the display module displays the second brightness, the third brightness, the fourth brightness and the third comparison result after receiving the second brightness, the third brightness, the fourth brightness and the third comparison result in step S63.

Therefore, a user can easily know according to the second brightness, the third brightness, the fourth brightness and the third comparison result, after the oxygen generation device is started, the oxygen concentration in the second chamber can be higher than 21%, and the combustion state of the combustible piece is a flame combustion state. When the oxygen generating device is opened for a first preset time and then closed for a third preset time, the oxygen concentration in the second chamber is reduced, but still higher than 21%, and the combustion state of the combustible element is still in a flame combustion state. After the oxygen generating device is started for the first preset time and then closed for the second preset time, the oxygen concentration in the second chamber is reduced to about 21%, and the combustion state of the combustible element is a flameless combustion state. Therefore, according to different combustion states, high-purity oxygen can be proved to be introduced into the second cavity when the oxygen generation device is started, and the reliability of the oxygen enrichment function of the air conditioner is improved.

It should be noted that the combustion state of the combustible element can be obtained by other means, for example, a first image of the combustible element in the first chamber is obtained through image acquisition modules such as a camera and a camera, a second image of the combustible element in the second chamber after the oxygen generator is started is obtained, the combustible element in the first image can be clearly seen to be in a flameless combustion state by comparing the first image with the second image, and the combustible element in the second image is obviously in a flameless combustion state, so that the oxygen generator can be proved to introduce high-purity oxygen into the second chamber when being started, the oxygen concentration in the second chamber is improved, and the reliability of the oxygen enrichment function of the air conditioner is increased. Obviously, after the oxygen generating device is opened for the first preset duration and then closed for the second preset duration, the third image of the combustible piece in the second chamber is acquired, the oxygen generating device is opened for the first preset duration and then closed for the third preset duration, the fourth image of the combustible piece in the second chamber is compared with the third image, the second image and the fourth image, the third image and the fourth image, and high-purity oxygen is introduced into the second chamber when the oxygen generating device is opened. The technical personnel in the field can flexibly select the specific means for acquiring the combustion state of the combustible element according to the specific application scene, and only need to prove that the oxygen generator can introduce high-purity oxygen into the second chamber when being started and increase the reliability of the oxygen enrichment function of the air conditioner.

After detecting that a human body enters the preset range, the reminding module can send a prompt of 'starting oxygen enrichment function display', and at the moment, oxygen enrichment function display can be started. Before the oxygen enrichment function is displayed, if the combustible element is in an extinguishing state, the combustible element needs to be ignited so as to give an intuitive feeling to a user. A possible implementation of igniting the combustible element is explained below in connection with fig. 7. FIG. 7 is a flow chart of igniting the combustible element after determining that a human body has entered the predetermined range, in accordance with an embodiment of the invention.

As shown in fig. 7, in a possible implementation, the function display method of the present invention further includes:

step S71: moving the ignition device to the combustible element by the first mechanical arm;

step S72: the combustible element is ignited by the ignition device.

In this embodiment, the display device further includes an ignition device and a first mechanical arm, and the ignition device is used for igniting the combustible element, for example, the ignition device is an electronic ignition gun, an electronic igniter, and the like. When the oxygen-enriched function is displayed, firstly, an ignition signal is generated by the signal generator, the ignition controller controls the on-off of a primary circuit of the ignition coil according to the signal sent by the signal generator, high voltage is generated in a secondary circuit, and the high voltage is sent to each spark plug through a voltage divider to realize ignition and ignite a combustible component.

The ignition device is clamped on a first mechanical arm, and the first mechanical arm is used for moving the ignition device to the position of the combustible element. For example, the first robot arm includes a first motor and a first rack-and-pinion, a first clamping portion is provided on a rack of the first rack-and-pinion, and the ignition device is clamped in the first clamping portion. Obviously, the first mechanical arm may also be composed of a first motor and a first push rod, the first push rod is provided with a first clamping portion, and the ignition device is clamped by the first clamping portion on the first push rod. Of course, the first mechanical arm may be arranged in other ways, and those skilled in the art may flexibly select the first mechanical arm according to a specific application scenario as long as the ignition device can be moved to the combustible element.

It should be noted that, the ignition device and the first mechanical arm may both be disposed outside the first gas collecting member and the second gas collecting member, and after detecting that a human body enters the preset range, the ignition device is driven by the first mechanical arm to move and pass through the opening to reach the combustible element. Obviously, the ignition device and the first mechanical arm can also be arranged in the first chamber and the second chamber, and after the fact that a human body enters a preset range is detected, the first mechanical arm is controlled to move to drive the ignition device to the position of the combustible element. Of course, the ignition device and the first mechanical arm may be arranged in other manners as long as the ignition device can be moved to the position of the combustible element by the first mechanical arm when the combustible element needs to be ignited, and then the combustible element is ignited by the ignition device without affecting the oxygen-enriched display function of the display device.

In step S71, after detecting that a human body enters the preset range, if the combustible element is in an extinguished state, the ignition device is moved to the combustible element by the control of the first mechanical arm to prepare for igniting the combustible element.

It should be noted that whether the combustible element is in the extinguished state may be determined by the image of the combustible element collected by the image collecting device, or may be determined by the brightness in the chamber detected by the brightness detecting device when the combustible element is located in the chamber. Of course, it is also possible to make all or a part of the first chamber and the second chamber from glass or transparent plastic such as polystyrene, acrylonitrile-butadiene-styrene copolymer, or other possible transparent materials, such as a conical flask, and observe whether the combustible element is in the extinguished state directly through the part made from the transparent material. Those skilled in the art can flexibly select the extinguishing device as long as the extinguishing device can accurately determine whether the combustible element is in the extinguishing state.

In step S72, the combustible element is ignited by the ignition device, so that the oxygen enrichment function can be performed.

Obviously, the display device may also include only an ignition device, not including the first mechanical arm, the ignition device being aligned with the combustible element, and the ignition device being controlled to ignite after detecting that a human body has entered the predetermined range.

Of course, the display device may not include the ignition device and the first mechanical arm, and after the human body is detected to enter the preset range, the combustible element may be manually ignited by the salesperson, and then the combustible element may be placed in the first chamber or the second chamber.

In one possible embodiment, the display device further comprises a second robotic arm, the combustible element being held by the second robotic arm. It should be noted that, the specific arrangement mode of the second mechanical arm may include a second motor and a second rack-and-pinion, the combustible element is clamped at a second clamping portion of a rack of the second rack-and-pinion, and may also include a second motor and a second push rod, and the combustible element is clamped at a second clamping portion of the second push rod. The structure of the second mechanical arm can be the same as or different from that of the first mechanical arm, and a person skilled in the art can flexibly select the second mechanical arm according to a specific application scene.

The ignition device, the first mechanical arm and the second mechanical arm are arranged outside the first gas collecting component and the second gas collecting component, after the fact that a human body enters a preset range is detected, the ignition device is moved to the position of the combustible piece through the first mechanical arm, the combustible piece is ignited through the ignition device, and at the moment, the ignited part of the combustible piece is in a flameless combustion state. The portion of the combustible element in the flameless combustion state is then inserted into the first chamber or the second chamber by the second robotic arm. When the combustible element is in the first chamber, the oxygen concentration is about 21%, and the combustion state of the combustible element is a flameless combustion state. When the combustible piece is in the second chamber, the oxygenerator is opened, then the oxygen concentration in the second chamber rises to more than 21% this moment, and the combustion state of combustible piece is the flame combustion state. In the first preset duration of the starting of the oxygen generating device and the third preset duration of the closing of the oxygen generating device, the oxygen concentration in the second chamber is higher than 21%, and the combustion state of the combustible piece is still in a flame combustion state. After the oxygen generating device is started for a first preset time and then closed for a second preset time, the oxygen concentration in the second chamber is about 21%, and the combustion state of the combustible piece is a flameless combustion state. Therefore, the oxygen generator can be well proved to be capable of introducing oxygen into the chamber, improving the oxygen concentration in the chamber and improving the reliability of the oxygen enrichment function of the air conditioner.

Of course, the display device may not include the second mechanical arm, and the combustible element may be manually inserted into the first chamber and the second chamber by a salesperson after the combustible element is ignited when performing the oxygen enrichment display.

In summary, in the preferred technical solution of the present invention, when it is detected that a human body enters the preset range of the air conditioner, the reminding module is controlled to send a prompt of "starting oxygen enrichment function display", so as to remind that the oxygen enrichment function display can be performed. By the control mode, the display can be displayed for the user in time, and the oxygen enrichment function of the air conditioner is displayed through the display device. When the oxygen enrichment function is shown, when the part that control combustible component is in flameless burning is located the second cavity, before or after, control oxygenerator opens, control warning module sends the suggestion of "opening the oxygen boosting" respectively, through the difference of the combustion state of combustible component in first cavity and second cavity, explain oxygenerator has produced the oxygen of high concentration really and has introduced in the cavity, the oxygen concentration in the cavity has been improved, make the user know the oxygen enrichment function of air conditioner directly perceivedly, improve the credibility of the oxygen enrichment function of air conditioner. When the part of the combustible element in flameless combustion is positioned in the first cavity, acquiring first brightness in the first cavity through a brightness detection module; when the part of the combustible element in flameless combustion is located in the second chamber, after the oxygen generation device is started for a first preset time and then closed for a second preset time, and after the oxygen generation device is started for the first preset time and then closed for a third preset time, the second brightness, the third brightness and the fourth brightness in the second chamber are respectively obtained through the brightness detection module. Upload first luminance, the second luminance, third luminance and fourth luminance to the show module, demonstrate these luminance values through the show module, thereby can see out combustible component more directly perceivedly in first cavity and when the different opportunity in the second cavity, the change of the combustion state of combustible component, thereby prove when oxygenerator opens, for oxygen has been introduced in the second cavity really, the oxygen concentration in the second cavity has been improved, the oxygen enrichment function's of air conditioner credibility has been increased, be favorable to the sale of product.
