Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent household appliances, for example to a method and device for high-temperature self-cleaning of an air conditioner, an air conditioner and a storage medium. BACKGROUND

[0002] Currently, high-temperature self-cleaning technology refers to a technology that, under the instruction of a specific program, the evaporator of an air conditioner indoor unit realizes cleaning of the heat exchanger of the air conditioner indoor unit by condensation and then dissolution of frost of the air conditioner evaporator. By automatically cleaning the evaporator of the air conditioner indoor unit, dust can be removed in time to prevent the breeding of bacteria inside the air conditioner, thereby ensuring the safety of air supply of the air conditioner. The high-temperature self-cleaning mode of the air conditioner currently usually includes an indoor unit self-cleaning stage and a high-temperature sterilization stage. When the air conditioner runs in the high-temperature self-cleaning mode, the indoor unit self-cleaning is run first, and then the high-temperature sterilization is run. However, in the high-temperature weather in summer, for small rooms and rooms with good heat preservation performance, the indoor temperature rises after the high-temperature sterilization stage is run, and the comfort is very poor, which will affect the comfort of the user.

[0003] A self-cleaning control method of an air conditioner is provided in the related art, comprising the following steps: S1, starting self-cleaning of the air conditioner; S2, entering the defrosting, sterilizing and drying mode in the self-cleaning of the air conditioner; S3, blowing air to the outdoor heat exchanger through a blowing device, and detecting the current dust concentration of the indoor heat exchanger; S4, adjusting the wind speed and volume of the indoor fan according to the detected dust concentration of the heat exchanger. To implement this method, an exhaust device needs to be arranged in the indoor unit of the air conditioner, and the exhaust device is installed at the bottom of one side of the air conditioner. The exhaust device comprises an exhaust duct and an exhaust fan, and the exhaust fan is used to blow the dust on the heat exchanger, and the indoor fan is used to help the dust to be discharged outside through the exhaust duct with hot air. The indoor fan controls its direction to guide the hot air generated in the high-temperature sterilizing and drying stage of the self-cleaning of the air conditioner to be led outside through the exhaust device.

[0004] This technical solution can discharge the hot air in the high-temperature sterilization stage outside to avoid affecting the indoor temperature, but it needs to increase an additional exhaust device on the air conditioner, the structure of the air conditioner is complex, and an exhaust hole needs to be additionally punched on the wall, which is high in cost when implemented.

[0005] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present application, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art.

[0031] In some embodiments, after the operation of the refrigeration according to the first indoor environment temperature, the method further includes:

[0032] In the case that the set condition is met, the refrigeration is exited.

[0033] In some embodiments, the set condition includes:

[0055] Unless otherwise specified, the term "a plurality of" means two or more.

[0056] In the embodiments of the present disclosure, the character " / " represents an "or" relationship between the objects before and after it. For example, A / B means A or B.

[0057] The term "and / or" is a description of an association relationship between objects, which means that there can be three relationships. For example, A and / or B means that there are three relationships of A or B, or A and B.

[0058] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0059] The embodiments of the present disclosure provide a method and device for high-temperature self-cleaning of an air conditioner, an air conditioner, and a storage medium, to solve the problem of complex structure of the air conditioner in the prior art solution to avoid high indoor temperature after high-temperature sterilization, affecting user comfort, and causing the air conditioner structure to be complex.

[0060] As shown in Figure 1 The embodiments of the present disclosure provide a method for high-temperature self-cleaning of an air conditioner, comprising:

[0061] S101, the air conditioner determines to start a high-temperature self-cleaning mode;

[0062] S102, the air conditioner acquires a first indoor environment temperature in a high-temperature sterilization stage;

[0063] S103, the air conditioner runs refrigeration according to the first indoor environment temperature in the case that the high-temperature sterilization stage ends.

[0064] By running refrigeration according to the first indoor environment temperature after the high-temperature sterilization stage ends, the temperature can be lowered in the case that the temperature is too high after the high-temperature sterilization ends, avoiding the indoor temperature being too high due to high-temperature self-cleaning, improving user comfort, and not needing to increase the hardware structure of the air conditioner, so that the air conditioner structure is simple and the implementation cost is low.

[0065] In the embodiments of the present application, the high-temperature self-cleaning mode includes three stages, including an indoor unit self-cleaning stage, a high-temperature sterilization stage, and an automatic refrigeration stage. In the embodiments of the present application, the first indoor environment temperature is acquired in the high-temperature sterilization stage, and then it is determined whether refrigeration needs to be run in the case that the high-temperature sterilization stage ends according to the first indoor environment temperature. If refrigeration needs to be run, the automatic refrigeration stage is entered. If refrigeration does not need to be run, the high-temperature self-cleaning mode is directly exited.

[0066] In some embodiments, as shown in Figure 2 The first indoor environment temperature is acquired, comprising:

[0067] S201, the air conditioner acquires the indoor environment temperature multiple times within a first set time;

[0068] S202, the air conditioner generates a mean value of the indoor environment temperature obtained multiple times as the first indoor environment temperature.

[0069] By determining the first indoor environment temperature according to the mean value, it is avoided that the obtained first indoor environment temperature is not accurate enough due to the difference of single sampling.

[0070] The multiple times of obtaining the indoor environment temperature can be periodic or random.

[0071] In some embodiments, the first set time is one minute before the end of the high-temperature sterilization stage.

[0072] By obtaining the indoor environment temperature one minute before the end of the high-temperature sterilization stage, the obtained first indoor environment temperature can be close to the indoor environment temperature at the end of the high-temperature sterilization stage.

[0073] In some embodiments, the method provided by the embodiments of the present disclosure further comprises:

[0074] The air conditioner obtains a second indoor environment temperature in the internal unit self-cleaning stage.

[0075] In some embodiments, as shown in Figure 3 The obtaining of the second indoor environment temperature comprises:

[0076] S301, the air conditioner obtains the indoor environment temperature multiple times within a second set time;

[0077] S302, the air conditioner generates a mean value of the indoor environment temperature obtained multiple times as the second indoor environment temperature.

[0078] By determining the second indoor environment temperature according to the mean value, it is avoided that the obtained second indoor environment temperature is not accurate enough due to the difference of single sampling.

[0079] The multiple times of obtaining the indoor environment temperature can be periodic or random.

[0080] In some embodiments, the second set time is

[0081] 30S to 60S in the internal unit self-cleaning stage.

[0082] The indoor environment temperature is obtained in 30S to 60S in the internal unit self-cleaning stage to generate the second indoor environment temperature, which can ensure that the generated second indoor environment temperature is close to the indoor environment temperature at the end of the internal unit self-cleaning stage.

[0083] In some embodiments, the internal unit fan runs at low wind for 60s and the compressor is not started in the internal unit self-cleaning stage.

[0084] In some embodiments, the running the refrigeration according to the first indoor environment temperature comprises:

[0085] The air conditioner runs the refrigeration when the first indoor environment temperature is greater than a set value and the first indoor environment temperature is higher than the second indoor environment temperature by a set difference.

[0086] By running the refrigeration when the first indoor environment temperature is greater than a set value and the first indoor environment temperature is higher than the second indoor environment temperature by a set difference, the refrigeration is run when the first indoor environment temperature is too high, and the refrigeration is not run when the first indoor environment temperature is moderate, thereby avoiding excessive energy consumption and avoiding the indoor environment temperature being too low due to excessive refrigeration, which affects the user's comfort.

[0087] In an embodiment, the set value can be 25℃, and the set difference can be 3℃. When the first indoor environment temperature is greater than a set value and the first indoor environment temperature is higher than the second indoor environment temperature by a set difference, the four-way valve is switched, and the refrigeration is run. In other cases, the high-temperature self-cleaning mode can be directly exited. In the refrigeration mode, the air volume of the indoor fan can be the default air volume.

[0088] In some embodiments, the running the refrigeration according to the first indoor environment temperature further comprises:

[0089] The air conditioner exits the refrigeration when a set condition is met.

[0090] In some embodiments, the set condition comprises:

[0091] The refrigeration running time reaches the running time of the high-temperature sterilization stage; or

[0092] The indoor environment temperature reaches the second indoor environment temperature; or

[0093] An instruction for exiting the high-temperature self-cleaning mode is received.

[0094] Because the user cannot set the remote control temperature, the indoor fan speed, etc. during the high-temperature self-cleaning, the high-temperature self-cleaning mode is exited when the refrigeration running time exceeds the high-temperature sterilization stage time. The overall running time is avoided from being too long.

[0095] By exiting the refrigeration when the refrigeration running time reaches the high-temperature sterilization stage running time, the refrigeration mode running time can be avoided to be too long, the high-temperature self-cleaning mode running time can be avoided to be too long, the user waiting time can be avoided to be too long, the user experience can be affected, and the user body comfort can be affected. By exiting the refrigeration when the indoor environment temperature reaches the second indoor environment temperature, the refrigeration mode running time can be avoided to be too long, the high-temperature self-cleaning mode running time can be avoided to be too long, the user waiting time can be avoided to be too long, the user experience can be affected, and the user body comfort can be affected. By exiting the refrigeration when the user inputted instruction of exiting the high-temperature self-cleaning mode is received, the user can be enabled to end the high-temperature self-cleaning mode by instructing the air conditioner to end the high-temperature self-cleaning mode when the user wants to end the high-temperature self-cleaning mode, the user demand can be met, and the user experience can be improved.

[0096] The instruction of exiting the high-temperature self-cleaning mode inputted by the user can be that the user clicks the high-temperature self-cleaning key again in the high-temperature self-cleaning mode.

[0097] As shown in Figure 4 The embodiment of the present disclosure further provides a method for high-temperature self-cleaning of an air conditioner, comprising:

[0098] S401, the air conditioner starts the high-temperature self-cleaning mode.

[0099] S402, the air conditioner acquires the indoor environment temperature for multiple times in 30S-60S in the inner machine self-cleaning stage.

[0100] S403, the air conditioner determines the average value of the acquired indoor environment temperatures as the second indoor environment temperature.

[0101] S404, the air conditioner acquires the indoor environment temperature for multiple times one minute before the end of the high-temperature sterilization stage.

[0102] S405, the air conditioner determines the average value of the acquired indoor environment temperatures as the first indoor environment temperature.

[0103] S406, the air conditioner runs the refrigeration in the case that the first indoor environment temperature is greater than or equal to 25℃, and the first indoor environment temperature minus the second indoor environment temperature is greater than 3℃.

[0104] S407, the air conditioner exits the refrigeration and ends the high-temperature self-cleaning mode in the case that the instruction of exiting the high-temperature self-cleaning mode inputted by the user is received.

[0105] S408, the air conditioner exits the refrigeration and ends the high-temperature self-cleaning mode in the case that the refrigeration running time reaches the second stage running time.

[0106] S409, the air conditioner exits the refrigeration and ends the high-temperature self-cleaning mode when the indoor environment temperature reaches the second indoor environment temperature for the first time.

[0107] If one of S407, S408 and S409 is met, the refrigeration is exited, and the high-temperature self-cleaning mode is ended.
