The embodiment of the disclosure provides a control method for an air conditioner, which may be a wall-mounted air conditioner or a cabinet air conditioner. The following description will specifically take a wall-mounted air conditioner as an example.

As shown in fig. 1, the air conditioner includes a heat exchanger 30, a wind wheel 40 or an indoor fan, a housing 10, and a structure for self-cleaning of a filter screen 20 of the air conditioner, the structure for self-cleaning of the filter screen 20 of the air conditioner includes the filter screen 20, the filter screen 20 is disposed at one side of the heat exchanger 30, and the filter screen 20 is used for filtering air flowing through the filter screen 20. The casing 10 defines an installation space 11, the heat exchanger 30 and the filter screen 20 are arranged in the installation space 11, the casing 10 is provided with an air outlet communicated with the installation space 11, and under the action of the wind wheel 40 or the indoor fan, air sequentially passes through the filter screen 20 and the heat exchanger 30 and then is blown out through the air outlet. The air outlet is provided with an air deflector 50, and the air deflector 50 is used for adjusting the air outlet direction of the air outlet.

The air conditioner further comprises a driving device, the driving device is in driving connection with the filter screen 20 and is used for driving the filter screen 20 to move relative to the heat exchanger 30, as shown in fig. 2, the control method comprises steps S201 to S203.

Step S201, responding to a filter screen self-cleaning instruction, controlling a driving device to drive a filter screen to move from an initial position to a cleaning position attached to a heat exchanger towards the heat exchanger.

When the filter screen 20 works normally, namely the position of the filter screen 20 close to the air inlet of the indoor unit is an initial position; the filter screen 20 further has a cleaning position abutting against the heat exchanger 30, as shown in fig. 1, in the cleaning position, the filter screen 20 abuts against the heat exchanger 30, and frosting of the filter screen 20 can be achieved by utilizing frosting of the heat exchanger 30, so that the filter screen 20 can be cleaned while the heat exchanger 30 is cleaned.

The filter screen 20 and the heat exchanger 30 are attached to each other at the cleaning position, wherein the attachment refers to two conditions that the filter screen 20 and the heat exchanger 30 are attached to each other and the distance between the filter screen 20 and the heat exchanger 30 is small, and frosting and defrosting of the heat exchanger 30 can drive the filter screen 20 to realize frosting and defrosting under the two conditions, so that the filter screen 20 can be cleaned while the heat exchanger 30 is cleaned.

The distance between the filter screen 20 and the heat exchanger 30 when the filter screen 20 is "in abutment" with the heat exchanger 30 is smaller than the distance between the filter screen 20 and the heat exchanger 30 in the operating position. In other words, when the filter screen 20 needs to be cleaned, the driving device drives the filter screen 20 to move toward the heat exchanger 30 and move to the cleaning position, and after the cleaning is finished, the driving device drives the filter screen 20 to move away from the heat exchanger 30 and move to the working position.

The driving device may include a motor and a transmission device, the transmission device may be a rack and pinion mechanism, an output shaft of the motor is connected with a gear for driving the gear to rotate, the rack is connected with the filter screen 20, the gear is engaged with the rack, the rotation of the motor drives the gear to rotate, and the gear drives the rack to move, thereby driving the filter screen 20 to move between the initial position and the cleaning position. Or, the driving device comprises a linear motor, and an output shaft of the linear motor is connected with the filter screen 20 to drive the filter screen 20 to move between the initial position and the cleaning position.

Step S202, sterilizing the filter screen.

Because the heat exchanger is attached to the filter screen, the filter screen is sterilized, the heat exchanger can be sterilized, the filter screen and the heat exchanger can be synchronously sterilized, and the independent sterilization operation of the filter screen and the heat exchanger is avoided.

And step S203, after the sterilization treatment is finished, controlling the driving device to drive the filter screen to move away from the heat exchanger and recover to the initial position, and enabling the air conditioner to work normally.

Optionally, in some embodiments, as shown in fig. 3, the control method includes steps S301-S305.

Step S301, responding to a filter screen self-cleaning instruction, controlling a driving device to drive a filter screen to move from an initial position to a heat exchanger to a cleaning position attached to the heat exchanger.

Optionally, in step S301, controlling the driving device to drive the filter screen to move from the initial position toward the heat exchanger to a cleaning position abutting against the heat exchanger includes:

the control driving device drives the filter screen to move from the initial position to the heat exchanger;

detecting the attaching degree between the filter screen and the heat exchanger in the movement process;

if the sticking degree reaches the preset sticking degree, controlling the driving device to stop working;

if the sticking degree does not reach the preset sticking degree, the driving device is controlled to continue working, and the filter screen is driven to continue moving towards the heat exchanger.

In the self-cleaning process of the filter screen 20, the cooling frosting and the heating defrosting of the heat exchanger 30 drive the filter screen 20 to froste and defrost, the cold and hot impact generated by the heat exchanger 30 makes the filter screen 20 generate certain deformation and prolong, so when the driving device moves to the same position at each time, the deformation of the filter screen 20 causes that the filter screen 20 can not be tightly attached to the surface of the heat exchanger 30, which means that the frost layer generated by the heat exchanger 30 can not be well spread to the surface of the filter screen 20, and the reduction of the frost quantity on the filter screen 20 can bring the reduction of the cleaning effect of the filter screen 20.

The abutting degree between the filter screen 20 and the heat exchanger 30 is detected, whether the filter screen 20 moves to the cleaning position or not is measured through the abutting degree, and therefore the filter screen 20 can abut against the heat exchanger 30 at the cleaning position no matter how the filter screen 20 deforms, and the cleaning position is accurately determined.

The attachment degree between the filter screen 20 and the heat exchanger 30 can be judged by detecting the distance between the filter screen 20 and the heat exchanger 30 through the infrared sensor, and the attachment degree between the filter screen 20 and the heat exchanger 30 can also be judged by detecting the magnitude of the acting force between the filter screen 20 and the heat exchanger 30. When the distance between the filter screen 20 and the heat exchanger 30 is smaller than or equal to the preset distance, the preset abutting degree is determined to be reached; when the acting force between the filter screen 20 and the heat exchanger 30 is greater than or equal to the preset acting force, the preset abutting degree is determined to be reached.

Step S302, the heat exchanger is cooled and frosted to drive the filter screen to froste.

The heat exchanger 30 is cooled, the surface of the heat exchanger 30 can be driven to frost through cooling, and the filter screen 20 is attached to the heat exchanger 30, so that the frosting of the heat exchanger 30 can drive the filter screen 20 to frost, and the dust on the surface of the filter screen 20 can be peeled off through the cold expansion effect generated by the frost layer on the surface of the filter screen 20, so that the filter screen 20 is cleaned.

The cooling and frosting of the heat exchanger can be realized by operating the refrigeration mode, and the heat exchanger can also be cooled by the cooling device, so that the cooling and frosting of the heat exchanger are realized.

Optionally, during the cooling and frosting treatment process of the heat exchanger, the driving device is controlled to drive the filter screen 20 to move relative to the heat exchanger 30, so as to drive the filter screen 20 to generate friction with the frost layer of the heat exchanger 30.

The filter screen 20 moves relative to the heat exchanger 30, so that the position of the filter screen 20 relative to the heat exchanger 30 can be changed, and therefore the position of the filter screen 20 relative to the frost layer on the heat exchanger 30 can be changed, and the filter screen 20 can generate friction with the frost layer on the heat exchanger 30 during the movement of the filter screen 20 relative to the heat exchanger 30, so that dust on the filter screen 20 is loosened.

When the heat exchanger 30 stops cooling and defrosting, the temperature of the heat exchanger 30 and the filter screen 20 rises, and the frost layer melts, so that the normal operation of the air conditioner is not influenced.

There are many ways to implement cooling and frosting treatment for the heat exchanger, for example, controlling the air conditioner to operate in a cooling mode to implement cooling and frosting of the heat exchanger, or setting a cooling device in the indoor unit to implement cooling and frosting of the heat exchanger through the cooling device.

Step S303, heating the heat exchanger to defrost so that the frost layer on the filter screen forms defrosting water.

The filter screen 20 is located at the cleaning position, so that when the subsequent heating and defrosting treatment is performed on the heat exchanger 30, the frost layer on the filter screen 20 can be driven to melt to form defrosting water, and when the defrosting water flows down from the filter screen 20, the dust on the filter screen 20 can be driven to flow down together, so that the filter screen 20 is cleaned.

Optionally, in the heating and defrosting process, the driving device is controlled to drive the filter screen to move relative to the heat exchanger so as to drive the defrosting water on the filter screen to flow.

In the heating and defrosting treatment process, the movement process of the filter screen is added, so that defrosting water on the filter screen can fluctuate and flow rapidly on the surface of the filter screen, dust accumulated on the surface of the filter screen can loosen along with fluctuation of the defrosting water, the adhesive force on the surface of the filter screen is reduced, the dust can slide down along with the sliding of the defrosting water more easily, and the effect of enhancing the surface cleaning effect of the filter screen is achieved.

The defrosting water flowing down from the filter screen flows into the water receiving tray and flows outdoors without action of a user.

The heat exchanger drives the surface of the filter screen to frost through the frost layer formed on the surface of the filter screen by cooling; the heat exchanger is heated to defrost, defrosting of the heat exchanger and the filter screen is achieved, defrosting water formed by melting of a frost layer on the surface of the heat exchanger carries dust on the heat exchanger, and defrosting water formed by melting of a frost layer on the surface of the filter screen carries dust on the filter screen. Therefore, the dust on the surfaces of the heat exchanger and the filter screen is cleaned by frosting and defrosting the heat exchanger and the filter screen.

And step S304, sterilizing the filter screen.

After dust on the surface of the filter screen is removed by defrosting the filter screen in the steps S302 and S303, the filter screen is sterilized, the heat exchanger is sterilized synchronously, and in the process that defrosting water flows down from the filter screen and the heat exchanger, the filter screen is sterilized at high temperature, so that microbes on the surfaces of the filter screen and the heat exchanger are sterilized, and the cleanliness of the filter screen and the heat exchanger is further improved.

And S305, after the sterilization treatment is finished, controlling the driving device to drive the filter screen to move away from the heat exchanger and restore to the initial position.

Optionally, in step S304, the filter screen is sterilized, which includes: and heating and sterilizing the heat exchanger to drive the filter screen to be heated to a first preset temperature so as to sterilize the filter screen.

In the cleaning position, the filter screen is closer to the heat exchanger. The heat exchanger is heated, the heat exchanger can drive the filter screen to be heated to a first preset temperature, and the first preset temperature is the temperature capable of killing most microorganisms, such as 55-60 ℃.

Adopt the mode that the heat exchanger heaied up, drive the filter screen and heat up to first preset temperature, realize the germicidal treatment to the filter screen, because heat exchanger and filter screen heat up in step, can realize disinfecting to the heat exchanger when disinfecting to the filter screen, moreover because the filter screen volume is far less than the volume of heat exchanger, the heat exchanger drives the filter screen more easily and heaies up to can guarantee to the intensification temperature of filter screen, guarantee the bactericidal effect to the filter screen.

Optionally, in step S303, performing a temperature-raising defrosting process on the heat exchanger, including:

and controlling the air conditioner to operate in a heating mode, wherein the operating frequency of a compressor of the air conditioner is a first preset frequency, and the rotating speed of an outdoor fan of the air conditioner is a first preset rotating speed.

Step S304, heating sterilization treatment is carried out on the heat exchanger, and the method comprises the following steps:

and controlling the air conditioner to continuously operate in a heating mode, and controlling the operating frequency of the compressor to be increased to a second preset frequency, wherein the rotating speed of the outdoor fan is a second preset rotating speed, the second preset frequency is greater than the first preset frequency, and the second preset rotating speed is greater than or equal to the first preset rotating speed.

There are many ways to perform temperature-raising defrosting treatment on the heat exchanger, for example, controlling the air conditioner to operate in a heating mode, or providing a heating device in the indoor unit, where the heating device is used to heat the heat exchanger to raise the temperature of the heat exchanger.

The heating mode of the air conditioner is adopted to realize heating and defrosting of the heat exchanger, no heating device is required to be additionally arranged, and the cost of the air conditioner is reduced.

When the temperature is raised and the frost is removed, the compressor is controlled to operate at a low frequency (a first preset frequency, such as 50Hz) so that the heat exchanger and the filter screen are at a lower temperature, the frost layer on the heat exchanger and the filter screen can be melted, and the energy consumption is saved. During the heating sterilization treatment, the compressor is controlled to operate at a high frequency (a second preset frequency, such as 80Hz) so that the temperature of the heat exchanger and the temperature of the filter screen are higher, and the filter screen and the heat exchanger are sterilized. Meanwhile, the rotating speed of the outdoor fan in the heating and defrosting treatment process is less than or equal to that of the outdoor fan in the heating and sterilizing treatment process, so that the rotating speed of the outdoor fan is adaptive to the temperature of the heat exchanger.

Optionally, in step S303, in the heating and defrosting process, the temperature of the heat exchanger is a second preset temperature, and the second preset temperature is less than the first preset temperature.

Before the sterilization process is performed on the filter screen in step S304, and optionally before the cooling and frosting process is performed on the heat exchanger in step S302, the control method further includes:

detecting the filth blockage degree of the filter screen;

and determining the treatment time of the sterilization treatment according to the filth blockage degree.

The larger the filth blockage degree of the filter screen is, the longer the sterilization treatment time is, and the sterilization effect on the filter screen is ensured.

The air conditioner comprises an indoor fan, and the control method further comprises the following steps:

in the sterilization treatment process, the indoor fan is controlled to rotate reversely to form air flow blown to the filter screen from the heat exchanger, and dust on the filter screen is blown by the air flow.

In the sterilization treatment process, the indoor fan is reversed, so that residual dust on the filter screen and the heat exchanger can be blown off, and the cleanliness of the heat exchanger and the filter screen is further improved.

Optionally, the control method further includes:

in the sterilization treatment process, the driving device is controlled to drive the filter screen to move relative to the heat exchanger.

The driving device drives the filter screen to move relative to the heat exchanger, the position of the filter screen relative to the heat exchanger is changed, and the relative position between the filter screen and the air flow formed by the reversal of the indoor fan can also be changed, so that the air flow can take away dust at different positions of the filter screen.

Optionally, in the sterilization process, the control driving device drives the filter screen to move in a variable speed relative to the heat exchanger.

Compare in the uniform motion, the filter screen is for heat exchanger variable speed motion, and the air current variable speed motion that the filter screen formed for indoor fan reversal like this for the effort between air current and the filter screen is stronger, and the dust on the filter screen can more be taken away to the air current.

Optionally, in the sterilization process, the control driving device drives the filter screen to move relative to the heat exchanger, and may drive the filter screen to reciprocate between a dust blowing position and a cleaning position, where the dust blowing position is located between an initial position and a working position, or may drive the filter screen to reciprocate along a surface of the heat exchanger (e.g., along a length direction or a width direction of the heat exchanger).
