In an embodiment of the present invention, as shown in fig. 1 and 2, the air conditioner may include a compressor 1, a four-way valve 3, an outdoor heat exchanger 6, an indoor heat exchanger 9, and a throttling part 8. The exhaust port of the compressor 1 is connected with the first end of the four-way valve 3, the second end of the four-way valve 3 is connected with one end of the indoor heat exchanger 9, the other end of the indoor heat exchanger 9 is connected with one end of the throttling component 8, the other end of the throttling component 8 is connected with one end of the outdoor heat exchanger 6, the other end of the outdoor heat exchanger 6 is connected with the third end of the four-way valve 3, and the fourth end of the four-way valve 3 is connected with the air return port of the compressor 1.
When the air conditioner operates in a heating mode, as shown in fig. 1 and fig. 3, the a/B and the C/D of the four-way valve 3 are switched on, a high-temperature high-pressure gaseous refrigerant coming out of the compressor 1 enters the indoor heat exchanger 9 through the a/B end of the four-way valve 3 to exchange heat (emit heat), a high-temperature high-pressure gas-liquid two-phase mixture after heat exchange is throttled and depressurized through the throttling component 8, a low-temperature low-pressure gas-liquid two-phase mixture after throttling and depressurization enters the outdoor heat exchanger 6 to exchange heat (absorb heat), and a low-temperature low-pressure gaseous refrigerant after heat exchange returns to the compressor 1 through the.
After the air conditioner is heated and shut down, the indoor heat exchanger 9 is in a high-temperature state, waste heat is diffused outwards, the inner core (the indoor heat exchanger) is in a hot expansion state, the air conditioner shell (the indoor shell) is placed in an indoor environment, and the shell is in a cold contraction holding state due to the fact that the indoor environment temperature is low, and abnormal sound is generated due to friction extrusion between the inner part and the outer part caused by the cold contraction of the shell and the hot expansion of the inner core.
In order to solve the problems, the invention provides a control method of an air conditioner, after the air conditioner is heated and shut down, the four-way valve of the air conditioner is subjected to reversing treatment, materials such as sponge, flannelette, adhesive tape and the like do not need to be additionally added, and the expansion with heat and contraction with cold generated in the heating and shut down process of the air conditioner are improved.
Fig. 5 is a flowchart of a control method of an air conditioner according to an embodiment of the present invention. As shown in fig. 5, the control method of the air conditioner according to the embodiment of the present invention may include the steps of:
and S1, controlling the four-way valve to change direction and controlling the indoor fan of the air conditioner to be in a closed state after the air conditioner is heated and shut down.
And S2, judging whether the four-way valve is reversed.

According to an embodiment of the present invention, during the start-up of the compressor, the outdoor fan of the air conditioner is also controlled to be in a turn-off state, and the indoor fan is controlled to be kept in a turn-off state.
Specifically, when the air conditioner operates in the heating mode, the a/B and the C/D of the four-way valve are turned on, as shown in fig. 3, a high-temperature and high-pressure gaseous refrigerant coming out of the compressor enters the indoor heat exchanger through the D/C of the four-way valve to exchange heat, then enters the outdoor heat exchanger after being throttled and depressurized by the throttling component, and then returns to the compressor through the a/B of the four-way valve after being subjected to heat exchange by the outdoor heat exchanger.
After the air conditioner is heated and shut down, the four-way valve of the air conditioner is reversed, the four-way valve is switched on in a D/A mode and a C/B mode, and as shown in figures 2 and 4, an indoor fan is in a closed state in the reversing process. After the four-way valve finishes reversing, the compressor is started to operate, and the outdoor fan is controlled to be in a closed state in the starting process. After the compressor is started to operate, as shown in fig. 2, high-temperature and high-pressure gaseous refrigerant coming out of the compressor firstly exchanges heat through the outdoor heat exchanger, after the gas-liquid two-phase mixture after heat exchange is throttled and depressurized through the throttling component, liquid refrigerant is sent into the indoor heat exchanger, and the liquid refrigerant absorbs the waste heat of the indoor heat exchanger, so that a core heat source of the air conditioner is eliminated, the core and the shell are synchronously in a cooling state, materials such as sponge, flannelette, adhesive tapes and the like do not need to be additionally added, and the expansion and contraction sound generated in the heating and shutdown process of the air conditioner is effectively improved.
Further, according to an embodiment of the present invention, after the compressor is started to operate for a preset time, the compressor is controlled to stop operating, and the four-way valve is controlled to reverse again to return to the initial state. The preset time can be calibrated according to actual conditions.
That is to say, after the four-way valve is reversed, and the compressor is started and operated for a period of time, the indoor heat exchanger and the shell of the indoor unit are in a synchronous cooling state, so that a heat source of the indoor heat exchanger is eliminated, the sound of expansion with heat and contraction with cold cannot occur, the compressor is controlled to stop operating, the four-way valve is controlled to be reversed again, and the four-way valve is restored to an initial state, namely the four-way valve is switched on in a D/C mode and switched on in an A/B mode during heating operation.
In summary, according to the control method of the air conditioner in the embodiment of the present invention, after the air conditioner is turned off for heating, the four-way valve is controlled to perform reversing, the indoor fan of the air conditioner is controlled to be in a closed state, whether the reversing of the four-way valve is completed is determined, and if the reversing of the four-way valve is completed, the compressor is controlled to start, so as to control the liquid refrigerant passing through the throttling component to flow through the indoor heat exchanger, so that the indoor heat exchanger and the casing of the indoor unit are in a synchronous cooling state. Therefore, the method can effectively improve abnormal sound generated by friction extrusion between the inner part and the outer part of the air conditioner in the heating shutdown process due to thermal expansion of the indoor heat exchanger and cold contraction of the indoor machine shell.
