Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

A water temperature control method for a water dispenser according to an embodiment of the first aspect of the present invention will be described below with reference to the accompanying drawings.

As shown in fig. 1 to 6, according to the water temperature control method for the water dispenser of the embodiment of the invention, the water dispenser comprises a water pump 300 and a heat generating component 200, the heat generating component 200 has a first power section 202 and a second power section 203, and the power of the first power section 202 is smaller than that of the second power section 203. For example, the first power segment 202 may be a plurality of power segments different from each other, and the second power segment 203 may be a plurality of power segments different from each other, and those skilled in the art may make corresponding adjustments according to specific situations.

Specifically, the water temperature control method for the water dispenser comprises the following steps:

collecting a first rotation speed of the water pump 300 required to heat water to a first standard temperature using the first power stage 202, and collecting a second rotation speed of the water pump 300 required to heat water to a second standard temperature using the second power stage 203, the first standard temperature and the second standard temperature being respectively a plurality of different from each other (correspondingly, the first rotation speed and the second rotation speed being respectively a plurality of different from each other);

setting the preset outlet water temperature of the water dispenser;

judging whether the preset outlet water temperature belongs to a first standard temperature:

if yes, starting the first power section 202 and controlling the rotating speed of the water pump 300 to be a corresponding first rotating speed;

otherwise, the second power stage 203 is started and the rotation speed of the water pump 300 is controlled to be the corresponding second rotation speed.

Wherein the first standard temperature and the second standard temperature are respectively a plurality of different from each other means that the first standard temperature is a plurality of different from each other, the second standard temperature is a plurality of different from each other, and a part of the first standard temperature may be equal to a part of the second standard temperature; correspondingly, the first rotation speeds are different from each other, and the second rotation speeds are different from each other. It is understood that the first reference temperature may correspond to a plurality of first rotational speeds, and the second reference temperature may correspond to a plurality of second rotational speeds.

For example, when the preset outlet water temperature is 100 ℃, the second power section 203 is started and the rotating speed of the water pump 300 is controlled to be 800 r/min; when the preset water outlet temperature is 40 ℃, starting the first power section 202 and controlling the rotating speed of the water pump 300 to be 1120 r/min; when the preset water outlet temperature is 49 ℃, the second power section 203 is started, and the rotating speed of the water pump 300 can be controlled to be 2080r/min, 2100r/min, 2120r/min, 2140r/min, 2160r/min or 2180 r/min.

In the prior art, if linear output of the power of the heating tube is to be realized, a driving circuit with increased power is needed, and the circuit occupies about half of the whole hardware cost, so that the cost is too high.

Therefore, according to the water temperature control method for the water dispenser provided by the embodiment of the invention, the heating element 200 with different power sections is utilized, the power of each power section is fixed, the corresponding power section is matched according to the preset outlet water temperature, and the rotating speed of the water pump 300 is matched, so that the purpose of controlling the outlet water temperature is achieved. Therefore, the nonlinear adjustment of the outlet water temperature is realized by matching the corresponding power section and controlling the rotating speed of the water pump 300, an expensive electronic circuit for controlling the heating tube to output linear power can be omitted, the cost is reduced, the full-range coverage of the outlet water temperature is realized, and the precision is higher.

According to some embodiments of the present invention, as shown in fig. 3, the water temperature control method for a water dispenser further includes:

judging whether the preset water temperature is equal to a first standard temperature:

if so, controlling the rotation speed of the water pump 300 to be a corresponding first rotation speed, that is, selecting the first power section 202 to heat the water;

otherwise, judging whether the preset water temperature is equal to the second standard temperature:

if so, controlling the rotation speed of the water pump 300 to be a corresponding second rotation speed, that is, selecting the second power section 203 to heat the water;

otherwise, the rotation speed of the water pump 300 corresponding to one of the first standard temperature and the second standard temperature with a small difference value with the preset outlet water temperature is selected.

In the specific embodiment shown in fig. 5 and 6, the first standard temperature is set to an integer value between 20 ℃ and 70 ℃, the second standard temperature is set to an integer value between 44 ℃ and 100 ℃, and the corresponding relationship between the first standard temperature and the first rotating speed, and the corresponding relationship between the second standard temperature and the second rotating speed are obtained through experiments, so that the temperature control process of water from normal temperature to 100 ℃ is realized. When a user sets an outlet water temperature, matching a set value (namely, a preset outlet water temperature) of the user with the temperature value in fig. 6, and if the value exists in the table, taking a corresponding rotating speed value of the water pump 300; if the table has no corresponding value, the temperature value which is most matched with the table and the corresponding rotating speed value of the water pump 300 are taken. Therefore, the accuracy of temperature control depends on the subdivision degree of the table, and the finer the numerical division in the table is, the closer the curve shown in fig. 5 is to the relationship curve between the rotation speed and the temperature of the water pump 300, so that the accuracy of temperature control is higher.

For example, the first standard temperatures and the second standard temperatures are values in the table shown in fig. 6, respectively, and when the preset water temperature is 85 ℃, the second power stage 203 is selected, and the rotation speed of the water pump 300 is controlled to be 910 r/min; when the preset water outlet temperature is 28 ℃, selecting the first power section 202, and controlling the rotating speed of the water pump 300 to be 1400r/min, 1420r/min or 1440 r/min; when the preset water outlet temperature is 75 ℃, the second power section 203 is selected, and the rotating speed of the water pump 300 can be controlled to be 1000r/min or 1020 r/min.

Optionally, when the preset outlet water temperature, the first standard temperature, and the second standard temperature are equal, the second power stage 203 may be started, and the rotation speed of the water pump 300 is controlled to be the corresponding second rotation speed. Therefore, the heating time is short, and the efficiency of the water dispenser is higher. For example, when the preset outlet water temperature is 56 ℃, the second power stage 203 is started, and the rotation speed of the water pump 300 can be controlled to be 1500r/min or 1520 r/min.

According to some embodiments of the present invention, when the preset outlet water temperature, the first standard temperature and the second standard temperature are equal, the first power stage 202 may be started to control the rotation speed of the water pump 300 to be the corresponding first rotation speed. Therefore, the low-power section is utilized for heating, the power consumption of the water dispenser is less, and the energy is saved. For example, when the preset outlet water temperature is 56 ℃, the first power stage 202 is started, and the rotation speed of the water pump 300 is controlled to be 900 r/min.

According to some embodiments of the present invention, as shown in fig. 4, the water temperature control method for a water dispenser further includes:

collecting the first rotating speed and the second rotating speed, and dividing the water outlet temperature range of the water dispenser into a first temperature zone and a second temperature zone, wherein the maximum temperature of the first temperature zone is less than or equal to the minimum temperature of the second temperature;

setting a preset water outlet temperature;

judging whether the preset outlet water temperature belongs to a first temperature zone:

if so, the first power segment 202 is initiated;

otherwise, the second power segment 203 is started;

judging whether the preset water temperature is equal to the first standard temperature or the second standard temperature:

if yes, controlling the rotating speed of the water pump 300 to be a corresponding first rotating speed or a second rotating speed;

otherwise, the rotation speed of the water pump 300 corresponding to one of the first standard temperatures or the second standard temperatures with a small difference value from the preset outlet water temperature is selected.

For example, if the outlet water temperature reached by the second power stage 203 when the rotation speed of the water pump 300 is maximum is 44 ℃, the division point is 44 ℃, 20 ℃ to 44 ℃ is set as the first temperature zone, and 44 ℃ to 100 ℃ is set as the second temperature zone. The first standard temperature is set to an integer value between 20 ℃ and 44 ℃ and the second standard temperature is set to an integer value between 44 ℃ and 100 ℃. When the preset outlet water temperature is 30 ℃, starting the first power section 202, and controlling the rotation speed of the water pump 300 to be a corresponding first rotation speed (for example, 1340r/min) because the preset outlet water temperature is equal to the first standard temperature; when the preset outlet water temperature is 30.2 ℃, the first power stage 202 is started, and since the difference between the preset outlet water temperature and 30 ℃ is smaller than the difference between the preset outlet water temperature and 31 ℃, the rotation speed of the water pump 300 is controlled to be the first rotation speed (for example, 1340r/min) corresponding to 30 ℃.

According to some embodiments of the present invention, the first power section 202 and the second power section 203 are formed by making the heat generating member 200 have different resistance values, so that the cost is low. Under the same applied voltage, the power of the first power segment 202 and the second power segment 203 with different resistance values are different, for example, the resistance value of the first power segment 202 is larger than that of the second power segment 203.

The main control panel 100 is arranged on the shell, and the water pump 300 and the heating element 200 are respectively communicated with the main control panel 100.

According to the water dispenser 10 provided by the embodiment of the invention, by utilizing the water temperature control method for the water dispenser, the nonlinear regulation of the outlet water temperature is realized by matching the corresponding power section and controlling the rotating speed of the water pump 300, an expensive electronic circuit for controlling the heating pipe to output linear power can be omitted, the cost can be reduced, the full-range coverage of the outlet water temperature is realized, and the precision is higher.

In this way, the selection of the first power segment 202 and the second power segment 203 can be realized by controlling the on/off of the tap 201 and the main control board 100.

According to some embodiments of the present invention, as shown in fig. 1, a plurality of taps 201 are arranged at intervals along a length direction of the heat generating member 200, and a first power segment 202 is defined between two taps 201 located at both ends of the heat generating member 200. For example, the taps 201 are three, and a second power segment 203 is defined between the middle tap 201 and the tap 201 at the end. Thus, the structure is simple and reliable.

According to some embodiments of the present invention, as shown in fig. 1, the heat generating member 200 includes: a heat generating tube 210 and a heat generating wire 220.

Thus, the main control panel 100 controls the start of a certain power section, the flow rate of water is controlled by adjusting the rotation speed of the water pump 300, and the water enters the heating tube 210 and is heated under the action of the heating wire 220, and then flows out through the water outlet.
