[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0027] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between various embodiments and / or settings discussed.

[0028] In an embodiment of the present application, as Figure 1 shown, the air conditioner may include an air handling unit, which is composed of a water receiving tray, a water receiving tray tilt angle adjustment device, a proportional adjustment water valve, a water outlet, an ultrasonic humidification device, a water receiving tray temperature surface detection and monitoring device, and an inlet pipe flow rate adjustment device. Among them, the water receiving tray is used to store the water generated during the operation of the air conditioner; the proportional adjustment water valve is used to control the drainage or water storage of the water receiving tray; the ultrasonic humidification device is responsible for humidity adjustment, and the water receiving tray temperature surface detection and monitoring device is used to detect the temperature of the heat preservation surface of the water receiving tray.

[0029] To solve the problem that in the prior art, a sponge is used for anti-condensation of the water receiving tray, and the anti-condensation effect is poor after a long time of use, the present application combines Figure 1 to provide a control method for an air conditioner, as Figure 2 shown, the steps of the method include:

[0030] Step 201, when the air conditioner operates at a preset temperature for a preset duration, detect the area of the low-temperature region on the heat preservation surface of the water receiving tray in the air conditioner;

[0031] In an embodiment of the present application, generally, the tilt angle of the water receiving tray can be adjusted through the water receiving tray tilt angle adjustment device so that the water receiving tray can store water. For example, the left and right tilt of the water receiving tray can be controlled so that the water in the water receiving tray can tilt in one direction, which is convenient for subsequent control of the water volume by the proportional adjustment water valve in the water receiving tray. In addition, the heat preservation surface of the water receiving tray in the embodiment of the present application mainly refers to the position where the water receiving tray stores water. Specifically, as Figure 1 the circled part in, that is, the temperature of the entire outer heat preservation surface area can be detected through the water receiving tray temperature surface detection and monitoring device, and different temperature regions can also be identified.

[0032] In addition, it should be noted that the preset temperature is set in real time according to different environments. For example, in summer when it is hotter, it can be set to 24 °C, and in winter it can be set to 28 °C, etc. The preset duration can also be set accordingly according to actual needs. The purpose is to perform subsequent detection after the air conditioner reaches a steady state. For example, the preset duration is 5 minutes, etc.

[0033] Step 202: When the low-temperature area is greater than or equal to the first preset threshold, detect the real-time temperature of the environment where the air conditioner is located.

[0034] Step 203: Obtain the absolute value of the real-time temperature and the second preset threshold, and determine whether to reduce the water flow rate into the water receiving tray and / or increase the preset temperature according to the comparison result between the absolute value and the third preset threshold.

[0035] In this regard, when the low-temperature area of the outer insulation surface of the water receiving tray exceeds the first preset threshold, it indicates that there is a high possibility of condensation in the current large low-temperature area of the water receiving tray, which may affect the normal operation of the air conditioner. Therefore, when the low-temperature area of the outer insulation surface of the water receiving tray exceeds the first preset threshold, corresponding measures need to be further taken to curb the expansion of the low-temperature surface and prevent the development of condensation. Specifically, if the current second preset threshold is 24°C and the third preset threshold is 2°C, the comparison result between the absolute value and the third preset threshold can be one of the following three cases: the real-time temperature is greater than 26°C or less than 22°C, or the real-time temperature is greater than 22°C and less than 26°C. If the current real-time temperature is within the range of 22°C to 26°C, it indicates that the current real-time temperature has met the preset temperature. Even if the current low-temperature area exceeds the first preset threshold, the possibility of condensation is relatively small and no further adjustment is required. If the real-time temperature is less than 22°C, it indicates that the current real-time temperature is still low and has not reached the preset temperature. Therefore, it is necessary to further reduce the current water volume flowing into the water receiving tray to reduce the possibility of condensation. Specifically, the water flow rate can be reduced by lowering the air damper, and then continue to operate according to the preset temperature to further increase the real-time temperature. If the real-time temperature is higher than 26°C, it indicates that the current real-time temperature exceeds the preset temperature. Even if the low-temperature area exceeds the first preset threshold at this time, the possibility of condensation is relatively low due to the high real-time temperature. However, to further ensure that no condensation occurs, while reducing the water flow rate, the preset temperature of the air conditioner operation is adjusted back to avoid the current real-time temperature dropping too much and increasing the possibility of condensation.

[0036] It can be seen that through the above steps 201 to 203, when the air conditioner operates at the preset temperature for the preset duration, the low-temperature area of the insulation surface of the water receiving tray in the air conditioner is detected. If the current low-temperature area is large, that is, exceeds the first preset threshold, the real-time temperature of the environment where the air conditioner is located is further detected, the absolute value of the real-time temperature and the second preset threshold is obtained, and it is determined whether to reduce the water flow rate into the water receiving tray and / or increase the preset temperature according to the comparison result between the absolute value and the third preset threshold to prevent the occurrence of condensation. It can be seen that in this application, by monitoring the low-temperature area and taking corresponding measures when the low-temperature area is large, that is, reducing the water flow rate into the water receiving tray and / or increasing the preset temperature to prevent the occurrence of condensation, compared with using a sponge for anti-condensation of the water receiving tray in the prior art, its anti-condensation effect is better and it does not affect the normal operation of the air conditioner.

[0037] In the embodiment of the present application, for the method of detecting the area of the low-temperature region on the heat-insulating surface of the water receiving tray involved in step 201 above, it may further include:

[0038] Step 11, detecting the area of the region on the heat-insulating surface of the water receiving tray where the real-time temperature is lower than the third preset threshold;

[0039] Step 12, determining the area of the low-temperature region as the area of the region where the real-time temperature is lower than the third preset threshold.

[0040] It can be seen that in the embodiment of the present application, the temperature of the heat-insulating surface of the water receiving tray can be detected by the Figure 1 water receiving tray temperature surface detection and monitoring device therein, and regions with different temperatures can be detected. That is, for regions with multiple different temperatures that may exist on the heat-insulating surface, the water receiving tray temperature surface detection and monitoring device can detect multiple regions with different temperatures, and can also determine the areas of the regions with different temperatures, so as to obtain the current area of the low-temperature region.

[0041] In an alternative embodiment of the embodiment of the present application, for the method of determining whether to reduce the water flow rate flowing into the water receiving tray and / or increase the preset temperature according to the comparison result between the absolute value and the third preset threshold involved in step 203 above, it may further include:

[0042] Step 21, when the absolute value is less than or equal to the third preset threshold, controlling the air conditioner to continue operating at the preset temperature;

[0043] Step 22, when the absolute value is greater than the third preset threshold and the real-time temperature is greater than or equal to the second preset threshold, reducing the water flow rate flowing into the water receiving tray and increasing the preset temperature;

[0044] Step 23, when the absolute value is greater than the third preset threshold and the real-time temperature is less than the second preset threshold, reducing the water flow rate flowing into the water receiving tray to prevent condensation on the water receiving tray.

[0045] It can be seen that in the embodiment of the present application, when the low-temperature area surface is greater than the first preset threshold, although condensation may occur, corresponding measures still need to be taken after comparing the current real-time temperature with the second preset threshold (preset temperature). Because if the current real-time temperature is within the allowable deviation range, for example, the current temperature is 27°C, the preset temperature is 29°C, and the allowable deviation range is 29°C ± 2°C, that is, 27°C is within this range, indicating that the ambient temperature is within the preset temperature range at this time. That is, the current larger low-temperature area surface should be generated when the low-temperature area decreases from a larger area to the current area during the rising process of the real-time temperature, that is, it means that the low-temperature area surface is decreasing. Therefore, although a larger low-temperature area surface appears currently, condensation will not occur. Therefore, there is no need to adopt measures to prevent condensation, and the air conditioner can operate normally. If the current real-time temperature is not within the range of 29°C ± 2°C, such as the real-time temperature is less than 27°C, it indicates that the current temperature is relatively low and a larger low-temperature area appears. Even if the current real-time temperature is rising, it is still at a relatively low temperature. Therefore, the possibility of condensation is relatively large, and corresponding measures need to be taken, that is, to reduce the water flow rate into the water receiving tray. Specifically, the air volume of the air conditioner can be reduced, thereby reducing the amount of water flowing into the water receiving tray to prevent condensation on the water receiving tray. If the real-time temperature is greater than 31°C, it indicates that the current real-time temperature is higher than the preset temperature. Therefore, when the air conditioner operates based on the preset temperature, the current real-time temperature will decrease, and at this time, a larger low-temperature area appears. If the real-time temperature continues to decrease, condensation will occur; in this case, in order to prevent condensation from occurring, the preset temperature needs to be increased by Δt°C. This Δt°C does not necessarily need to be directly adjusted to be the same as the current real-time temperature, and the comfort of the environment needs to be considered. That is, after increasing the preset temperature by Δt°C, the preset temperature may still be lower than the real-time temperature. At this time, the real-time temperature is still decreasing under the action of the air conditioner, and condensation may still occur. Therefore, at this time, it is also necessary to reduce the water flow rate into the water receiving tray to prevent condensation from occurring.

[0046] In the embodiment of the present application, on the premise of preventing condensation on the water receiving tray, the proportional adjustment water valve of the water receiving tray and the humidifying device can be further controlled to adjust the humidity of the current environment, so as to further meet the user's demand for the relative humidity of the air. Based on this, the method of the embodiment of the present application, as Figure 3 shown, further includes:

[0047] Step 301, detecting the real-time relative humidity of the environment where the air conditioner is located, and obtaining the absolute value of the real-time relative humidity and the fourth preset threshold;

[0048] Step 302, determining the comparison result between the absolute value and the fifth preset threshold, and controlling the proportional adjustment water valve of the water receiving tray and the humidifying device according to the comparison result to adjust the relative humidity of the environment where the air conditioner is located.

[0049] It can be seen that through the above steps 301 to 302, when there is no condensation on the current water receiving tray, the proportional regulating water valve and the humidifying device of the water receiving tray can be further controlled to adjust the relative humidity of the environment where the air conditioner is located.

[0050] For the above steps, the method of determining to control the proportional regulating water valve and the humidifying device of the water receiving tray according to the comparison result to adjust the relative humidity of the environment where the air conditioner is located may further include:

[0051] Step 31, when the absolute value is less than or equal to the fifth preset threshold, control the proportional regulating water valve of the water receiving tray to be fully open, and maintain the air conditioner to continue running at the current preset temperature;

[0052] Step 32, when the absolute value is greater than the fifth preset threshold, control the proportional regulating water valve and the humidifying device of the water receiving tray to adjust the relative humidity of the environment where the air conditioner is located.

[0053] In this regard, that the absolute value is less than or equal to the fifth preset threshold indicates that the current real-time relative humidity is within the preset deviation range. For example, if the fourth preset threshold (preset humidity) is 50%, and the allowable deviation range is 50% ± 5%. If the current real-time relative humidity is 48%, then the current real-time relative humidity is within the preset deviation range, that is, there is no need to adjust the current real-time relative humidity, that is, the water receiving tray does not need to store water, so the proportional regulating water valve of the water receiving tray can be fully open. If the current real-time humidity is not within the preset deviation range, that is, the current real-time relative humidity is less than 45% or greater than 55%, it indicates that the current real-time relative humidity cannot meet the user's needs and needs to be adjusted. Based on this, for the method of controlling the proportional regulating water valve and the humidifying device of the water receiving tray involved in the above step 32 to adjust the relative humidity of the environment where the air conditioner is located, it may further include:

[0054] Step 41, when the real-time relative humidity is less than or equal to the fourth preset threshold, control the proportional regulating water valve to close, and control the humidifying device to turn on according to the first ratio to perform the humidifying function;

[0055] Step 42, when the real-time relative humidity is greater than the fourth preset threshold, obtain the comparison result between the duration for the real-time relative humidity to drop to the fourth preset threshold and the sixth preset threshold, and control the proportional regulating water valve and the humidifying device according to the comparison result to adjust the relative humidity of the environment where the air conditioner is located.

[0056] As can be seen from the above steps 41 and 42, if the current real-time relative humidity is less than or equal to the fourth preset threshold, it indicates that the current real-time relative humidity cannot meet the user's needs and needs to be adjusted, that is, humidification is required to increase the relative humidity. Therefore, in this case, the proportional regulating water valve needs to be closed to make the water receiving tray enter the water storage state, and then the humidifying device is started at the first ratio for humidification. In a specific example, the first ratio can be determined by the current real-time relative humidity and the fourth preset threshold. For example, the first ratio = 1 - real-time relative humidity / fourth preset threshold, that is, the lower the current real-time relative humidity, the larger the first ratio, the larger the opening of the humidifying device, and the more obvious the humidifying effect. If the current real-time relative humidity is greater than the fourth preset threshold, it indicates that humidification is not required at present, but dehumidification is required. And the air conditioner has a dehumidifying effect during normal operation. Dehumidification is also equivalent to adjusting the relative humidity of the current environment. Specifically, how to dehumidify can further calculate the duration for the current real-time relative humidity to drop to the fourth preset threshold, and after comparing this duration with the sixth preset threshold, determine the dehumidifying method. Based on controlling the proportional regulating water valve and the humidifying device according to the comparison result involved in the above step 42 to adjust the relative humidity of the environment where the air conditioner is located, it can further include:

[0057] Step 51, when the duration for the real-time relative humidity to drop to the fourth preset threshold is less than or equal to the sixth preset threshold, control the humidifying device to close and control the proportional regulating water valve to open at the second ratio;

[0058] Step 52, when the duration for the real-time relative humidity to reach the fourth preset threshold is greater than the sixth preset threshold, control the above-mentioned humidifying device to close and control the proportional regulating water valve to be fully open.

[0059] It can be seen that if the duration for the current real-time relative humidity to drop to the fourth preset threshold is long, the proportional regulating water valve can be directly fully opened without water storage, and dehumidification is carried out through the normal operation of the air conditioner to reduce the current relative humidity to meet the user's needs. If the duration for the current real-time relative humidity to drop to the fourth preset threshold is short, the proportional regulating water valve can be opened at the second ratio, that is, the proportional regulating water valve is not fully open, but a certain amount of water is kept in the water receiving tray. If the dehumidifying effect is fast and the real-time relative humidity is reduced to less than the fourth preset threshold, humidification can also be carried out through the humidifying device. The second ratio can be determined by the current real-time relative humidity and the fourth preset threshold. For example, the second ratio = real-time relative humidity / fourth preset threshold - 1, that is, the larger the real-time relative humidity, the larger the second ratio, indicating that the water storage loss in the water receiving tray is faster at this time, and humidification is not required in this case; if the real-time relative humidity is smaller, the second ratio is smaller, indicating that the water storage loss in the water receiving tray is slower at this time, so as to prevent there is enough water in the water receiving tray for humidification after the real-time relative humidity is lower than the fourth preset threshold.

[0060] The present application will be explained and illustrated below in conjunction with the specific implementation manners of the embodiments of the present application. The specific implementation manners provide a method for jointly adjusting and controlling the anti-condensation of a water receiving tray. Specifically, in combination with Figure 1 it can be seen that the method for jointly adjusting and controlling the anti-condensation of the water receiving tray, as Figure 4 shown, includes:

[0061] Step 401: Start the air-conditioning unit and set the target parameters;

[0062] Among them, the target parameters include the target temperature T 设 , and this target temperature corresponds to the above-mentioned preset temperature.

[0063] Step 402: The unit operates for m minutes, that is, it operates for m minutes according to the target parameters;

[0064] Among them, this m minutes corresponds to the above-mentioned preset duration. In addition, the value of m can be set accordingly according to actual needs, such as m = 5 min.

[0065] Step 403: Start the water receiving tray temperature surface detection and monitoring device, that is, first set the low-temperature surface temperature threshold T 阈 = T 凝露点 + t0, and detect the low-temperature area surface S i of the outer heat preservation surface of the water receiving tray based on the set low-temperature surface temperature;

[0066] Step 404: Judge whether the low-temperature surface S i exceeds the critical value c (corresponding to the above-mentioned first preset threshold). If S i < c, return to Step 402. If S i ≥ c, execute Step 405;

[0067] Step 405: Detect the current real-time temperature T i ;

[0068] Step 406: Compare whether |T i - T 设 | is less than or equal to b (temperature tolerance coefficient). If so, return to Step 402. If so, execute Step 407;

[0069] Step 407: Judge whether T i is greater than T 设 . If so, execute Step 408. If not, execute Step 409;

[0070] Step 408: Reduce the water flow rate △i or reduce the wind speed and at the same time callback (rise) T 设， by callback △t °C, and then execute Step 402;

[0071] Step 409: Reduce the water flow rate △i or reduce the wind speed, and then execute Step 402.

[0072] As can be seen from the above steps 401 to 409, in the present application, the pre-condensation area on the outer surface of the water receiving tray component can be steadily monitored. When the area of the low-temperature region reaches the critical point, the condensation joint adjustment control logic intervenes, compares the immediate target temperature difference situation, and classifies and adjusts the air volume or water flow rate, so as to perform temperature callback control, reduce condensation generation, etc., and achieve the prevention of condensation on the outer surface of the water receiving tray from forming.

[0073] Combined with Figure 1 , this specific implementation provides a method for joint adjustment control of the condensed water on the water receiving tray. As Figure 5 shown, the steps of this method include:

[0074] Step 501: Start the unit and set the target parameters;

[0075] Among them, the target parameters include the target temperature T 设 , and the relative humidity ψ 设 .

[0076] Step 502: The unit runs for m minutes and runs for m minutes according to the target parameters;

[0077] Step 503: Detect the real-time relative humidity ψ i ;

[0078] Step 504: Judge the deviation between the relative humidity and the target, |ψ i - ψ 设 | > p, where p is the allowable deviation value; if not, the water inlet proportional regulating valve is fully opened, and it returns to step 502; if so, execute step 505;

[0079] Step 505: Compare whether ψ i is greater than ψ 设 , if not, execute this step 506; if so, execute step 507;

[0080] Step 506: The proportional regulating water valve is closed, and the humidifier is opened according to the proportional coefficient k2, k2 = 1 - ψ i / ψ 设 , and then return to step 502.

[0081] Step 507: Calculate the time t i when the relative humidity reaches the set value;

[0082] Step 508: Compare t i and the time threshold T0, and judge whether t i ≤ T0, if not, execute step 509; if so, execute step 510;

[0083] Step 509: The water inlet proportional regulating valve is fully opened, and it returns to step 502;

[0084] Step 510, adjust the proportional water valve and according to coefficient K i Open, K i =(ψi / ψset)-1;

[0085] Step 511, the water receiving tray enters the water storage state and returns to Step 502.

[0086] Through the above steps 501 to 511, during the operation of the air handling unit, the real-time air humidity is detected, and then the immediate target humidity difference is compared. Classified control is carried out, and the ratio of the condensate generation amount to the demand amount in the future period of time in this case is pre-calculated, and the drain port control and humidity adjustment strategy are executed. Thus, the humidity of the indoor air is adjusted to meet the comfort requirements.

[0087] Corresponding to the above Figure 2 , an embodiment of the present application provides a control device for an air conditioner, as Figure 6 shown, the device includes:

[0088] The first detection module 602 is used to detect the area of the low-temperature region on the heat preservation surface of the water receiving tray in the air conditioner when the air conditioner operates at a preset temperature for a preset duration;

[0089] The second detection module 604 is used to detect the real-time temperature of the environment where the air conditioner is located when the area of the low-temperature region is greater than or equal to the first preset threshold;

[0090] The first control module 606 is used to obtain the absolute value of the real-time temperature and the second preset threshold, and determine whether to reduce the water flow rate flowing into the water receiving tray and / or increase the preset temperature according to the comparison result between the absolute value and the third preset threshold.

[0091] Through the device of the embodiment of the present application, when the air conditioner operates at a preset temperature for a preset duration, the area of the low-temperature region on the heat preservation surface of the water receiving tray in the air conditioner is detected.

[0094] In an alternative embodiment of the present application, the second control module in the embodiment of the present application may further include: a fourth control unit, configured to control the proportional adjustment water valve of the water receiving tray to be fully open and maintain the air conditioner to continue operating at the current preset temperature when the absolute value is less than or equal to the fifth preset threshold; and a fifth control unit, configured to adjust the relative humidity of the environment where the air conditioner is located by controlling the proportional adjustment water valve and the humidifying device of the water receiving tray when the absolute value is greater than the fifth preset threshold.

[0095] In an alternative embodiment of the present application, the fifth control unit in the embodiment of the present application may further include: a first control subunit, configured to control the proportional adjustment water valve to close and control the humidifying device to turn on at a first ratio to perform a humidifying function when the real-time relative humidity is less than or equal to the fourth preset threshold; and a second control subunit, configured to obtain the comparison result between the duration when the real-time relative humidity drops to the fourth preset threshold and a sixth preset threshold, and control the proportional adjustment water valve and the humidifying device according to the comparison result to adjust the relative humidity of the environment where the air conditioner is located.

[0096] In an alternative embodiment of the present application, the second control subunit in the embodiment of the present application is configured to perform the following steps: control the humidifying device to turn off and control the proportional adjustment water valve to open at a second ratio when the duration when the real-time relative humidity drops to the fourth preset threshold is less than or equal to the sixth preset threshold; and control the humidifying device to turn off and control the proportional adjustment water valve to be fully open when the duration when the real-time relative humidity reaches the fourth preset threshold is greater than the sixth preset threshold.

[0097] In an alternative embodiment of the embodiment of the present application, the first detection module in the embodiment of the present application may further include: a detection unit configured to detect the area of the region where the real-time temperature in the heat preservation surface of the water receiving tray is lower than a third preset threshold; and a processing unit configured to determine the area of the region where the real-time temperature is lower than the third preset threshold as the low-temperature region area.
