Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Fig. 1 is a front view of an air purifying assembly and a filter screen of an air conditioner in this embodiment, and as shown in fig. 1, the air conditioner includes a filter screen 1, an air purifying assembly 2, and a plurality of resistance strain gauges 3. Wherein, the filter screen 1 is universal with the filter screen of the existing air conditioner, and the air purification component 2 is produced and assembled separately; the air purification component 2 comprises an external skeleton structure and an internal purification sheet structure, and the internal purification sheet structure can comprise a plurality of layers of sheets with different purification functions and can be customized according to the individual requirements of users; the resistance strain gauge 3 is arranged on the air purification component 2. The mounting position of the resistance strain gauge 3 comprehensively considers the simplicity of the dismounting and mounting operations of the resistance strain gauge when a user replaces the air purification assembly.

Referring to the left side view of the air cleaning assembly and the filter screen of the air conditioner shown in fig. 2 and the top view of the air cleaning assembly and the filter screen of the air conditioner shown in fig. 3, the filter screen 1 and the air cleaning assembly 2 are fixed by a limit buckle, and the air cleaning assembly 2 is arranged at the side close to the evaporator.

Referring to fig. 4, a partial schematic view of a filter screen and an air purification assembly is shown, taking an example that the air purification assembly includes 3 purification layers with different functions, specifically, the air purification assembly sequentially includes: a dust-cleaning layer 21, a harmful gas-cleaning layer 22, and a virus-cleaning layer 23.

Wherein, the filter screen can increase the commonality of material, and the large granule floater in the entrapment air-removing can prolong the life of air purification part simultaneously, reduces later stage user's maintenance cost.

In the air purification assembly 2, the layer 1 is a dust purification layer 21, materials such as filter non-woven fabrics and the like can be added into the layer (the filter non-woven fabrics contain a network structure capable of being electrified, so that a stable electrostatic field can be generated, and a good dust filtration effect can be achieved), under the action of the electrostatic field, dust such as PM2.5, PM0.3 and the like in the air is intercepted, the dust concentration in the indoor air is reduced, and the harm to a human body is reduced; the layer 2 is a harmful gas purification layer, which can decompose the molecules of harmful gases such as formaldehyde into carbon dioxide and water molecules through catalytic reaction of chlorophyll and the like under the conditions of normal illumination, weak light and even no light, and the reaction is more thorough than that of a photocatalyst, sub-decomposition products cannot be generated, secondary pollution cannot be generated, and the harmful gas purification layer is more favorable for guaranteeing the body health of a user; the 3 rd layer is a virus purification layer which can directly adsorb and inactivate viruses by adding a virus inactivation catalysis material so as to prevent the viruses from generating harm to human bodies. Meanwhile, the virus inactivation catalytic material is solid and non-toxic, is insoluble in water and organic solvents, can be prepared into particles, nets or be loaded on various carriers, realizes virus adsorption inactivation, and has inactivation efficiency of 96.5-99.9%.

When each purifying layer in the air purifying assembly is replaced, only the panel of the air conditioner internal unit is opened, the filter screen is pushed out from the mounting buckle, so that the gap of the air purifying assembly (the upper part of the front view shown in figure 1) faces to a user, the connecting circuit of the resistance strain gauge and the controller is disconnected, and then the purifying materials in the harmful gas purifying layer and the virus purifying layer are taken out and replaced; for the dust purification layer, because the resistance strain gauge is arranged on the surface of the purification material to measure the filth blockage state, the resistance strain gauge is required to be taken down firstly when the material of the layer is replaced/cleaned, then the resistance strain gauge is arranged on the dust purification layer after the replacement/cleaning, and then the resistance strain gauge and the controller are connected.

The above-mentioned air conditioner that this embodiment provided, on the basis that does not change current structure, through newly-increased air purification subassembly, can play the function such as the little dust in the room air of removing, toxic gas such as formaldehyde, ammonia, benzene and benzene series and inactivation virus, effectively reduce the little dust in the air, harmful gas content and virus content, ensure that the room air is healthy.

Fig. 5 is a schematic flow chart of a control method of an air cleaning assembly in an embodiment of the invention. The method of fig. 5 may be applied to an air conditioner, and the air purification assembly includes at least one of the following purification layers: a dust purification layer, a harmful gas purification layer and a virus purification layer; the method comprises the following steps:

and S502, when a detection trigger instruction is received, acquiring a purification effect parameter corresponding to the air purification assembly.

The corresponding purification effect parameters of the air purification assembly can comprise at least one of the following parameters: dirty blocking parameters, gas concentration variation parameters of an inlet and an outlet, and virus concentration variation parameters of an inlet and an outlet.

Optionally, the detection trigger instruction may be a shutdown instruction, a startup instruction, a preset periodic detection instruction, or a detection instruction actively input by a user. When the air conditioner receives the detection triggering instruction, the purification effect parameters are obtained and correspond to various purification layers possibly included by the air purification assembly, and the purification effect parameters can include dirty blockage parameters, gas concentration change parameters of an inlet and an outlet or virus concentration change parameters of the inlet and the outlet.

In this embodiment, a dirty blockage parameter may be obtained by a sensor disposed on the dust purification layer, where the dirty blockage parameter is used to indicate a dirty blockage degree of the dust purification layer, and the dirty blockage degree may be directly or indirectly detected by the sensor, for example, indirectly determine the dirty blockage degree through resistance changes of the resistance strain gauge at different times; the gas concentration change parameter can be obtained through the detection value of the gas concentration sensor; the virus concentration variation parameter can be obtained by the detection value of the virus concentration sensor.

S504, judging whether the air purification assembly meets the preset updating condition or not according to the purification effect parameters. If yes, go to S506; if yes, no prompt operation is performed.

Based on the above-mentioned purification effect parameters, the current purification capacity of the air purification assembly can be determined. It can be understood that as the using time increases, the current purifying capacity is continuously reduced until the purifying effect of the air conditioner is influenced. Therefore, the current purification capacity of the air purification assembly needs to be continuously detected to determine whether the current purification capacity meets the preset updating condition, and if so, a user is prompted to replace or clean the air purification assembly; if not, no prompt operation is carried out.

Wherein, whether the preset updating condition is met or not can be determined by comparing the purification effect parameter with a preset parameter threshold range. Specifically, the specific value of the parameter threshold range may be determined through experiments or actual operating data of the air conditioner.

And S506, prompting to update the information of the air purification assembly.

Under the condition that the air purification assembly meets the preset updating condition, the information of the air purification assembly needs to be prompted to a user to replace or clean the air purification assembly in time. The specific prompting mode may include: the display panel of the air conditioner displays that the air purification assembly needs to be updated, prompts that the air purification assembly needs to be updated through the air conditioner prompt tone, and sends information that the air purification assembly needs to be updated to an intelligent terminal connected with the air conditioner.

The control method of the air purification assembly provided by the embodiment comprises at least one of the following purification layers: dust purifies layer, harmful gas and purifies layer, virus and purifies the layer, when receiving to detect trigger command, can acquire the purifying effect parameter that the air purification subassembly corresponds to judge whether the air purification subassembly accords with predetermined renewal condition according to the purifying effect parameter, if accord with predetermined renewal condition, then indicate the air purification subassembly and need update. According to the method, the purification capacity of the air purification assembly can be effectively monitored by judging the purification effect parameters of the air purification assembly, and when the purification effect parameters meet the preset updating conditions, a user can be automatically reminded of updating the air purification assembly, so that the air purification effect of the air conditioner is ensured.

Hereinafter, a control method of the air cleaning assembly will be described in detail by taking an example in which the air cleaning assembly includes a dust cleaning layer.

The resistance strain gauge is arranged on the dust purification layer and attached to the surface of the dust purification layer, when particles such as dust are attached to the dust purification layer, the metal wire/metal foil of the resistance strain gauge is stressed and deformed, and the length and the cross section area of the metal wire/metal foil are changed, so that the resistance is changed. The adhesion density of the particles on the dust purification layer can be represented based on the above resistance change, and specifically, the difference between the initial resistance value and the operation resistance value corresponding to the dust purification layer is taken as the dirty blocking parameter. The initial resistance value is a first resistance detection value of the dust purification layer or a resistance detection value after the dust purification layer is replaced/cleaned, and the operation resistance value is a resistance detection value obtained after a detection trigger instruction is received.

Optionally, in the above S504, it may be determined whether the filth blockage parameter is greater than or equal to a preset filth blockage threshold, and if the filth blockage parameter is greater than the preset filth blockage threshold, it is determined that the air purification assembly meets a preset update condition. The first resistance value of the resistance strain gauge in a brand new state of the dust purification layer and the second resistance value of the resistance strain gauge in a state that the dust purification layer cannot effectively purify dust can be predetermined, and the difference value between the second resistance value and the first resistance value is used as the preset filth blockage threshold value. And in the running process of the air conditioner, if the detected filth blockage parameter is larger than or equal to the preset filth blockage threshold value, the situation that the dust purification layer cannot effectively purify the air is indicated, and the dust purification layer needs to be replaced/cleaned in time.

Considering that the user needs to continuously measure the dust-cleaning layer for a long period of time after replacing/cleaning the dust-cleaning layer, the initial resistance value needs to be updated since the cleaning ability of the dust-cleaning layer may be changed due to the replacement/cleaning. Based on this, the above method may further include the steps of:

a1, judging whether the dust cleaning layer is renewed. The dust purification layer needs to be detached from the air conditioner when being replaced/cleaned, and the resistance strain gauge arranged on the dust purification layer needs to be disconnected with a controller, a power supply and the like of the air conditioner, so that whether the dust purification layer is detached or not can be determined through a power-off signal of the resistance strain gauge, and whether the dust purification layer is updated or not can be judged.

Firstly, if a starting signal is received, whether a power-off signal corresponding to the resistance strain gauge is received or not is judged. If the power-off signal is received, the fact that the user possibly detaches the dust purification layer is indicated, and the current resistance change condition is continuously judged under the condition. And if the power-off signal corresponding to the resistance strain gauge is not received, executing the starting action of the air conditioner.

Then, the current resistance value is detected and whether the current resistance value is smaller than the running resistance value is judged. If the user replaces/cleans the dust purification layer, the current resistance value will be smaller than the running resistance value before replacement/cleaning. Therefore, if the current resistance value is smaller than the operation resistance value, the air purification assembly is determined to be updated. If the current resistance value is larger than or equal to the running resistance value, determining that the air purification assembly is not updated; in this case, the user needs to be continuously prompted to update the air purification assembly information.

A2, if the dust cleaning layer is updated, updating the initial resistance value corresponding to the dirty parameter.

If the dust-cleaning layer is updated, the initial resistance value can be updated to the current resistance value. And when the dirt blocking parameters corresponding to the dust purification layer are judged subsequently, the updated initial resistance value is taken as a reference.

Hereinafter, a control method of the air cleaning assembly will be described in detail by taking an example in which the air cleaning assembly includes a harmful gas cleaning layer and/or a virus cleaning layer.

The air inlet and the air outlet of the air conditioner are respectively provided with a harmful gas concentration detection sensor and a virus concentration detection sensor, and the actual purification effect is determined according to the change conditions of the harmful gas concentration of the air inlet and the air outlet.

Optionally, in the above S504, whether the gas concentration variation parameter and the virus concentration variation parameter meet the preset update condition may be determined by whether they are smaller than the corresponding threshold values. Specifically, the following steps may be included:

a1, judging whether the gas concentration variation parameter is less than or equal to a preset first gas concentration threshold value and/or whether the virus concentration variation parameter is less than a preset first virus concentration threshold value.

The gas concentration variation parameter and the virus concentration variation parameter may be concentration difference values of the gas inlet and the gas outlet, or concentration variation rates of the gas inlet and the gas outlet. After the air passes through the harmful gas purification layer and the virus purification layer, the concentration of the harmful air and the virus carried by the air is reduced, and the purification capability of the harmful gas purification layer and the virus purification layer can be represented by the concentration change parameters.

If the gas concentration variation parameter and the virus concentration variation parameter are smaller than the corresponding threshold values, one possibility is: the purification capacities of the harmful gas purification layer and the virus purification layer are insufficient, and the update condition is determined to be met at the moment; another possibility is: the concentration of harmful air and viruses in the air is low, and the concentration change parameters of the air inlet and the air outlet are small, so that the concentration change parameters are smaller than corresponding threshold values, and at the moment, the accumulated working time needs to be judged.

It should be noted that if the gas concentration variation parameter is greater than the preset second gas concentration threshold value and/or the virus concentration parameter is greater than the preset second virus concentration threshold value, ventilation is prompted and/or information for maintaining continuous operation of the air conditioner is kept. Wherein the second gas concentration threshold is greater than the first gas concentration threshold. If the gas concentration variation parameter is larger than a preset second gas concentration threshold value, the harmful gas purification layer is indicated to purify a large amount of harmful gas; and if the virus concentration parameter is greater than the preset second virus concentration threshold value, indicating that the absolute value of the virus concentration of the environment where the air conditioner is located is at a higher level. In both cases, the user may be prompted to ventilate or to keep the air conditioner running continuously to continuously purify toxic gases and viruses.

A2, if at least one of the condition that the gas concentration variation parameter is less than or equal to the preset first gas concentration threshold value and the condition that the virus concentration variation parameter is less than the preset first virus concentration threshold value are satisfied, acquiring the corresponding running time of the harmful gas purification layer and/or the virus purification layer. The operation time is the accumulated operation time of the harmful gas purification layer and/or the virus purification layer, and the operation time is increased on the basis of the previous accumulated operation time every time the air conditioner is started.

A3, if the running time is larger than or equal to the preset running time threshold value, determining that the harmful gas purification layer and/or the virus purification layer meet the preset updating condition; and if the running time is less than the running time threshold, determining that the harmful gas purification layer and/or the virus purification layer do not meet the updating condition.

It can be understood that if the operation time is greater than or equal to the preset operation time threshold, it indicates that the harmful air and virus concentration in the air is not low, and it is determined that the preset update condition is met. By judging the running time, the misjudgment probability of the updating of the air purification component can be reduced.

Similarly to the case of the aforementioned user's replacement/cleaning of the dust purification layer, the user needs to perform continuous long-term measurement of the harmful gas purification layer and/or the virus purification layer after replacing it, and thus needs to perform a zeroing operation on the operation time thereof. Based on this, the above method may further include the steps of: judging whether the harmful gas purifying layer and/or the virus purifying layer are updated; and if the running time of the harmful gas purification layer and/or the virus purification layer is updated, clearing the running time corresponding to the harmful gas purification layer and/or the virus purification layer.

In an embodiment, the dust purification layer, the harmful gas purification layer, and the virus purification layer may be sequentially disposed, and the dust purification layer is closest to the filter screen of the air conditioner, so that the dust purification layer needs to be detached first when the harmful gas purification layer and the virus purification layer are replaced. The above-described process of judging whether the harmful gas purification layer and/or the virus purification layer has been renewed may be implemented based on the resistance strain gauge of the dust purification layer.

S605, detecting the current resistance value R_iAnd judging whether the current resistance value is less than R_{Front side}. If yes, go to S606; if not, go to step S607.

Specifically, Δ R may be calculated_ii＝R_{Rear end}-R_{Front side}If Δ R_iiNot less than 0, determining that the dust purification layer is not replaced/cleaned by the user, and determining the current resistance value R_i"not assigned to the initial resistance value R_i0(ii) a If Δ R_iiIf the resistance value is less than 0, the user is judged to replace/clean the dust purification layer, and the current resistance value R is compared_iIs assigned to an initial resistance value R_i0。

S606, the user does not replace/clean the dust purification layer, the current resistance value R_i"not assigned to the initial resistance value R_i0。

S607, the user replaces/cleans the dust purification layer and compares the current resistance value R_iIs assigned to an initial resistance value R_i0. Considering the later maintenance cost and the change of the resistance strain sheet state caused by the manual disassembly and assembly of the dust purification layer, the initial resistance value of the resistance strain sheet needs to be continuously adjusted according to the actual measurement value.

And S806, the air conditioner does not perform any prompt operation.

S807, judging whether the running time is greater than or equal to a preset running time threshold t_b. If yes, go to S808; if not, go to step S806.

The running time accumulation program of the virus purification layer is started every time the air conditioner is started. If running time t₇≥t_bNamely, it is determined that the operation for an excessively long time results in a reduction in the cleaning effect of the virus cleaning layer, and the replacement virus cleaning layer is displayed on the display panel. In particular at intervals t₇Scrolling display is performed for 15 min. If t₇＜t_bThat is, it is determined that the concentration of the viruses in the current indoor air is too low, so that the purification efficiency of the virus purification layer is reduced, and therefore, the display panel does not perform any prompt response.

And S809, judging whether a power-off signal is received. If yes, go to S810; if not, go to S808.

Since the resistance strain gauge is powered off during the replacement process, if a power-off signal is received, the virus purification layer is replaced, and t is executed₇Clearing operation; if the power-off signal is not received, it indicates that the virus purification layer is not replaced, and S808 is executed again.
