Detailed Description

So that the manner in which the features and elements of the disclosed embodiments can be understood in detail, a more particular description of the disclosed embodiments, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings. In the following description of the technology, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, one or more embodiments may be practiced without these details. In other instances, well-known structures and devices may be shown in simplified form in order to simplify the drawing.

Generally, after an air conditioner is used or placed for a period of time, dust, impurities and the like are attached to the surfaces of heat exchangers of an indoor unit and an outdoor unit, and if the heat exchangers are not cleaned in time, the heat exchange efficiency of the heat exchangers is affected, and the air quality of the indoor environment is also affected. For this reason, the air conditioner is provided with a self-cleaning function to periodically clean heat exchangers of the indoor and outdoor units.

Fig. 1 is a schematic flowchart of a method for self-cleaning control of an air conditioner according to an embodiment of the disclosure. As shown in fig. 1, the method for self-cleaning control of an air conditioner includes:

s110, after the air conditioner enters a self-cleaning mode, determining the operating parameters of the air conditioner according to the ambient temperature and the ambient humidity;

and S120, controlling the air conditioner to operate according to the operation parameters, and defrosting the surface of the heat exchanger.

Specifically, after a self-cleaning control instruction sent by the terminal equipment is received, the air conditioner is controlled to enter a self-cleaning mode according to the self-cleaning control instruction; then, controlling the electronic expansion valve to reduce the temperature of the heat exchanger to be below the dew point temperature, and controlling a fan to continuously bring the moisture in the air to the surface of the heat exchanger for condensation; and further, adjusting the electronic expansion valve to reduce the surface temperature of the heat exchanger, and simultaneously closing the fan to quickly frost the surface of the heat exchanger. Here, the terminal device may be a mobile terminal such as a remote controller, or may be a wireless communication device such as a mobile phone, which is not limited by the embodiment of the present disclosure.

It should be understood that the manner of controlling the air conditioner to enter the self-cleaning mode is not limited to controlling the air conditioner to enter the self-cleaning mode according to the self-cleaning control command as described above, for example, the cleanliness of the heat exchanger may be detected, and the air conditioner may be controlled to enter the self-cleaning mode when the cleanliness is less than or equal to a preset value, where the cleanliness detection may be implemented by detecting the amount of dust and other parameters; alternatively, the air conditioner is controlled to periodically enter the self-cleaning mode in a timing manner, which is not limited by the embodiment of the disclosure.

And then, detecting the environmental temperature of the environment where the heat exchanger is located through a temperature sensor, detecting the environmental humidity of the environment where the heat exchanger is located through a humidity sensor, and determining the operating parameters of the air conditioner according to the detected environmental temperature and the detected environmental humidity.

It should be noted that the environmental temperature is not limited to be detected by the temperature sensor as described above, and for example, the estimated environmental temperature may be corrected according to the distribution rule by using a temperature algorithm and based on the temperature data detected by the defrosting temperature sensor, the coil temperature sensor, and the like; or the power meter is used for corresponding to different powers through different environmental temperatures under the condition of fixing the system state, and the environmental temperature is reversely deduced by fitting a function curve through the power.

Further, it should be noted that the ambient humidity is not limited to the detection by the humidity sensor as described above, and may be calculated based on parameters such as ambient temperature, wind speed, power, and the like by using a humidity algorithm, for example.

Furthermore, the air conditioner is controlled to operate according to the determined operation parameters, the rotating speed of the fan is increased by adjusting the electronic expansion valve to quickly defrost the surface of the heat exchanger, and dust, impurities and the like attached to the heat exchanger are washed by water formed by defrosting, so that the purpose of cleaning the heat exchanger is achieved.

Further, the self-cleaning strategy of the air conditioner may include a single self-cleaning mode and a multiple self-cleaning mode, wherein the multiple self-cleaning mode may include performing two or more self-cleaning. After the air conditioner starts the multi-time self-cleaning mode, the indoor unit of the air conditioner can be automatically cleaned for two times or more, and then the outdoor unit of the air conditioner can be automatically cleaned for two times or more by controlling the reversing of the four-way valve. It should be understood that the number of self-cleaning operations may be a default number of system operations, e.g., 3, 5, etc.; or the number of operation times may be preset as required, for example, 1 time, 2 times, etc.; or, whether the next self-cleaning is needed or not may be determined by the dust deposition thickness detected by the infrared sensor or the air volume of the air outlet detected by the air volume sensor, which is not limited in the embodiment of the present disclosure.

According to the technical scheme provided by the embodiment of the disclosure, after the air conditioner enters the self-cleaning mode, the operation parameters of the air conditioner are determined according to the environment temperature and the environment humidity, the air conditioner is controlled to operate according to the operation parameters, so that the surface of the heat exchanger is defrosted, and the operation parameters of the air conditioner can be adaptively adjusted according to the environment temperature and the environment humidity, so that the accurate control of the self-cleaning function of the air conditioner is realized, the defrosting is more thorough, and the user experience is improved.

In some embodiments, determining an operating parameter of the air conditioner based on the ambient temperature and the ambient humidity comprises: and determining the operating parameters of the air conditioner according to the temperature range of the ambient temperature and the humidity range of the ambient humidity.

Specifically, after the ambient temperature and the ambient humidity are obtained, the ambient temperature and the ambient humidity may be respectively compared with a preset temperature range and a preset humidity range, and a temperature range and a humidity range corresponding to the ambient temperature and the ambient humidity are respectively selected from the preset temperature range and the preset humidity range according to a comparison result; further, the operation parameters of the air conditioner are determined according to the temperature range corresponding to the ambient temperature and the humidity range corresponding to the ambient humidity.

Here, the temperature range may include a first temperature range, which is a low temperature, 10 ℃ to 20 ℃, i.e., greater than or equal to 10 ℃ and less than 20 ℃, a second temperature range, and a third temperature range; the second temperature range is middle temperature, 20-30 ℃, namely higher than or equal to 20 ℃ and lower than 30 ℃; the third temperature range is high, 30 ℃ to 40 ℃, i.e. higher than or equal to 30 ℃ and lower than or equal to 40 ℃.

Further, the temperature and humidity range can be obtained by arranging and combining the ambient temperature and the ambient humidity. The temperature and humidity range may include high temperature and high humidity, high temperature and medium humidity, high temperature and low humidity, medium temperature and medium humidity, medium temperature and low humidity, low temperature and high humidity, low temperature and medium humidity, and low temperature and low humidity, wherein high temperature and high humidity means that the ambient temperature is 30 ℃ to 40 ℃ and the ambient humidity is 70% or more, high temperature and medium humidity means that the ambient temperature is 30 ℃ to 40 ℃ and the ambient humidity is 40% or less, medium temperature and high humidity means that the ambient temperature is 20 ℃ to 30 ℃ and the ambient humidity is 70% or more, medium temperature and medium humidity means that the ambient temperature is 20 ℃ to 30 ℃ and the ambient humidity is 40% or less, medium temperature and low humidity means that the ambient temperature is 20 ℃ to 30 ℃ and the ambient humidity is 40% or less, low temperature and high humidity means that the ambient temperature is 10 ℃ to 20 ℃ and the ambient humidity is 70% or more, the low temperature and medium humidity means that the ambient temperature is 10-20 ℃ and the ambient humidity is 40-70% of the relative humidity, and the low temperature and low humidity means that the ambient temperature is 10-20 ℃ and the ambient humidity is less than 40% of the relative humidity.

It should be noted that the temperature ranges below 10 ℃ and above 40 ℃ are not suitable for the self-cleaning operation of the air conditioner, and therefore, the air conditioner will not enter the self-cleaning mode when the ambient temperature is in the temperature range below 10 ℃ or in the temperature range above 40 ℃.

Further, a preset corresponding relationship exists between the temperature and humidity range and the operation parameters of the air conditioner, that is, different temperature and humidity ranges correspond to different operation parameters.

For example, assuming that the detected ambient temperature is 24 ℃ and the ambient humidity is 50% of the relative humidity, the temperature and humidity range where the air conditioner is located can be determined to be medium temperature and medium humidity, and it is determined that the defrosting time needs to be adjusted to 2 minutes, the opening of the electronic expansion valve is adjusted to 480, the frequency of the compressor is adjusted to 50 hz, and the rotating speed of the fan is adjusted to 600 rpm.

According to the technical scheme provided by the embodiment of the disclosure, the operation parameters of the air conditioner are adaptively adjusted according to the ambient temperature and the ambient humidity, so that the accurate control of the self-cleaning function of the air conditioner is realized, the defrosting is more thorough, and the user experience is improved.

In some embodiments, the operating parameters include one or more of a defrosting time period, an electronic expansion valve opening, a compressor frequency, a fan speed.

Specifically, after the ambient temperature and the ambient humidity are obtained, one, two or more of the defrosting time of the air conditioner, the opening degree of the electronic expansion valve, the frequency of the compressor and the rotating speed of the fan can be adjusted according to the temperature range of the ambient temperature and the humidity range of the ambient humidity. For example, when the ambient temperature is 15 ℃ and the ambient humidity is 60% of relative humidity (i.e., low temperature and medium humidity), four operation parameters, namely the defrosting time, the opening of the electronic expansion valve, the frequency of the compressor and the rotating speed of the fan, can be adjusted; when the ambient temperature is 28 ℃ and the ambient humidity is 30% relative humidity (namely, medium temperature and low humidity), the three parameters of defrosting time, compressor frequency and fan rotating speed can be adjusted on the basis of low temperature and medium humidity as described above.

It should be noted that the operation parameters of the air conditioner are not limited to the defrosting time, the opening degree of the electronic expansion valve, the frequency of the compressor, and the rotation speed of the fan, for example, the operation parameters may further include the deposition thickness, the air volume at the air outlet, the temperature of the coil, and the like, which is not limited in this disclosure.

According to the technical scheme provided by the embodiment of the disclosure, the operation parameters of the air conditioner are adjusted according to the ambient temperature and the ambient humidity, different self-cleaning operation parameters can be adopted for different types of air conditioners, and therefore the intelligence of the air conditioner is improved, and the self-cleaning degree of the air conditioner is improved.

In some embodiments, the lower the humidity range in which the ambient humidity is located, the shorter the defrosting time period.

Specifically, the ambient humidity is proportional to the defrosting time, that is, the lower the humidity range of the ambient humidity is, the shorter the defrosting time is; conversely, the higher the humidity range of the environmental humidity, the longer the defrosting time. For example, when the detected ambient humidity is in the first humidity range below 40% relative humidity, the defrosting time needs to be adjusted to be as short as, for example, 0.5 minutes; and when the detected ambient humidity is in the third humidity range of 70% or more of the relative humidity, the defrosting time period needs to be adjusted to be long, for example, 3 minutes.

Optionally, in some embodiments, the lower the temperature range in which the ambient temperature is, the longer the defrosting time period.

Specifically, the ambient temperature is inversely proportional to the defrosting time, that is, the lower the temperature range in which the ambient temperature is located, the longer the defrosting time; on the contrary, the higher the temperature range of the environment temperature is, the shorter the defrosting time is. For example, when the detected ambient temperature is in a first temperature range of 10 ℃ to 20 ℃, the defrosting time needs to be adjusted to be as long as 3 minutes, for example; and when the detected ambient temperature is in a third temperature range of 30-40 ℃, the defrosting time needs to be adjusted to be as short as, for example, 0.5 minutes.

Optionally, in some embodiments, the lower the temperature range in which the ambient temperature is, the greater the electronic expansion valve opening.

Specifically, the ambient temperature is inversely proportional to the opening degree of the electronic expansion valve, that is, the lower the temperature range in which the ambient temperature is located, the larger the opening degree of the electronic expansion valve; conversely, the higher the temperature range in which the ambient temperature is, the smaller the opening of the electronic expansion valve. For example, when the detected ambient temperature is in a first temperature range of 10 ℃ to 20 ℃, the opening degree of the electronic expansion valve needs to be adjusted to be, for example, 480; when the detected ambient temperature is in the third temperature range of 30 to 40 ℃, the opening degree of the electronic expansion valve needs to be reduced to 200, for example.

Alternatively, in some embodiments, the lower the temperature range in which the ambient temperature is, the lower the compressor frequency.

Specifically, the ambient temperature is proportional to the compressor frequency, that is, the lower the temperature range in which the ambient temperature is located, the lower the compressor frequency; conversely, the higher the temperature range in which the ambient temperature is, the higher the compressor frequency. For example, when the detected ambient temperature is in a first temperature range of 10 ℃ to 20 ℃, the compressor frequency needs to be adjusted down to, for example, 40 hz; and when the sensed ambient temperature is in a third temperature range of 30 c to 40 c, the compressor frequency needs to be adjusted up to, for example, 55 hz.

Optionally, in some embodiments, the fan speed is a first fan speed when the ambient temperature is in a first temperature range; when the environment temperature is in a second temperature range, the rotating speed of the fan is the rotating speed of a second fan; the first temperature range is lower than the second temperature range, and the rotating speed of the first fan is lower than that of the second fan.

Specifically, when the ambient temperature is in a first temperature range of 10 ℃ to 20 ℃, the fan speed is a first fan speed, i.e., 300 rpm to 500 rpm, preferably 400 rpm; the fan speed is a second fan speed, i.e. 500 to 700 rpm, preferably 600 rpm, when the ambient temperature is in a second temperature range of 20 to 30 ℃; that is, in the case where the first temperature range is lower than the second temperature range, the first fan rotational speed is lower than the second fan rotational speed.

Optionally, in some embodiments, the fan speed is a second fan speed when the ambient temperature is in a second temperature range; when the environment temperature is in a third temperature range, the rotating speed of the fan is the rotating speed of the third fan; and the second temperature range is lower than the third temperature range, and the rotating speed of the second fan is higher than that of the third fan.

Specifically, when the ambient temperature is in the second temperature range of 20 ℃ to 30 ℃, the fan speed is the second fan speed, i.e., 500 rpm to 700 rpm, preferably 600 rpm; when the ambient temperature is in a third temperature range of 30-40 ℃, the fan speed is a third fan speed, i.e. 300-500 rpm, preferably 400 rpm; that is, in the case where the second temperature range is lower than the third temperature range, the second fan rotational speed is greater than the third fan rotational speed.

It should be noted that the first fan rotation speed may be the same as the third fan rotation speed, or may be different from the third fan rotation speed, which is not limited in the embodiment of the present disclosure.

Optionally, in some embodiments, one, two or more of the defrosting time period, the opening degree of the electronic expansion valve, the frequency of the compressor and the rotating speed of the fan may be adjusted simultaneously according to the temperature range of the ambient temperature and the humidity range of the ambient humidity.

For example, when the detected ambient temperature is in a first temperature range of 10 ℃ to 20 ℃ and the ambient humidity is in a first humidity range of 40% or less of the relative humidity, the defrosting time may be adjusted to 2.5 minutes, and the opening of the electronic expansion valve may be adjusted to 480; or the defrosting time can be adjusted to 2.5 minutes, the opening of the electronic expansion valve is adjusted to 480, and the frequency of the compressor is adjusted to 40 Hz; alternatively, the defrosting time may be adjusted to 2.5 minutes, the opening of the electronic expansion valve may be adjusted to 480, and the frequency of the compressor may be adjusted to 40 hz, and the rotation speed of the fan may be adjusted to 400 rpm, which is not limited in the embodiment of the present disclosure.

According to the technical scheme provided by the embodiment of the disclosure, one, two or more of the operation parameters of the air conditioner can be adjusted at will according to needs, so that the flexibility of adjusting the operation parameters of the air conditioner is improved.

All the above optional technical solutions may be combined arbitrarily to form optional embodiments of the present application, and are not described herein again.
