The embodiment of the invention also provides a control method of the air conditioner, wherein the air conditioner comprises the wall-mounted air conditioner indoor unit in any embodiment. The air conditioner control method may include:
when the dust shielding plate 50 needs to remove dust, the first driving device drives the dust shielding plate 50 to move between a position of completely shielding the air inlet and a position far away from the air inlet; and rotates the roller brush 61. When the dust-shielding plate 50 removes dust, the dust-shielding plate 50 moves from at least a position where the air inlet is completely shielded to a position away from the air inlet. Preferably, the dust mask 50 is repeatedly opened and closed three times.
When the dust collection box 62 needs to remove dust, the air conditioner firstly enters an evaporator frosting mode so as to frost the indoor unit of the air conditioner; the air conditioner then enters an evaporator defrosting mode to defrost the air conditioner, so that defrosting water enters the dust box 62, and dust in the dust box 62 is flushed out of the dust box 62. When the dust collection box 62 needs to remove dust, the whole machine enters an evaporator frosting mode to quickly frost the evaporator 30. Then, judging that frosting is finished according to the acquired data of the temperature points of the coil pipes of the evaporator 30, and stopping the whole machine; then the air conditioner indoor unit can directly enter an evaporator defrosting mode or enter an evaporator defrosting mode after n seconds of press protection time, so that the evaporator 30 can quickly defrost, enough potential energy and enough liquid water are formed, the water flows into the dust collecting box 62, dust in the dust collecting box 62 is washed out of the wall-mounted air conditioner indoor unit, and the function of automatically cleaning dust falling on the surface of the dust shielding plate 50 is realized.
Specifically, the evaporator frosting mode may be: the fan 40 of the wall-mounted air conditioner indoor unit is not operated, and the air deflector of the air guiding mechanism is in a minimum air outlet gear; the fan of the outdoor unit of the air conditioner is in an operating state; the compressor of the air conditioner operates, wherein when the compressor is a variable frequency compressor, the variable frequency compressor is operated at the maximum frequency, and when the compressor is a fixed frequency compressor, the fixed frequency compressor is operated normally; further, if the throttling device is an adjustable throttling device, for example, when the expansion valve is used, the temperature point of the coil of the evaporator 30 is used as a basis, if the temperature of the coil is higher than Tv1, the opening of the expansion valve is reduced by 3 to 8 units from the initial opening after every preset time until reaching the set minimum opening; if the throttling device is a throttling device such as a capillary tube and the like which cannot regulate the flow, the throttling device is not required to be controlled.
When the temperature of the coil pipe is lower than Tv2, the compressor is stopped, and the four-way valve is reversed to enter an evaporator defrosting mode. The evaporator defrost mode may be: the compressor can be started again, and when the compressor is a variable frequency compressor, the variable frequency compressor is operated at the maximum frequency. Further, if the throttling device is an adjustable type throttling device, such as an expansion valve, the set opening degree can be entered; so that the evaporator 30 is heated to defrost, thereby achieving the effect of generating a large amount of water to wash dust in the dust box in a short time.
Further, when the dust shielding plate 50 or the dust collecting box 62 needs to remove dust, the air conditioner can send out alarm signals such as sound and light to alarm.
Further, the air conditioner control method may further include: judging whether the dust shielding plate 50 needs dust removal according to a first preset program; and judging whether the dust box 62 needs dust removal according to the second preset program. Wherein the first preset program is configured to: when receiving the air conditioner start signal, judging whether a first time interval between the last dust removal of the dust shielding plate 50 and the current start of the air conditioner is longer than or equal to a first preset time length, and if the first time interval is longer than or equal to the first preset time length, judging that the dust shielding plate 50 needs to remove dust; or, receiving the first dust removing instruction from the user, it is determined that the dust shielding plate 50 needs to remove dust. After the dust removal is determined according to whether the first time interval is greater than or equal to the first preset time period, the dust shielding plate 50 is located at a position far from the air inlet after the dust removal of the dust shielding plate 50 is finished. The second preset program is configured to: when the air conditioner start signal is received, judging whether a second time interval between the last dust removal of the dust collection box 62 and the current start of the air conditioner is greater than or equal to a second preset time length, and if the second time interval is greater than or equal to the second preset time length, judging that the dust collection box 62 needs to remove dust; or, receiving the second dust removing instruction from the user, it is determined that the dust box 62 needs dust removal. When the air conditioner works according to the first instruction of the user or the second instruction of the user, the effect is obvious on the special condition of staged dust fall.
In some embodiments of the present invention, the air conditioner control method may further include: when the filter screen 70 needs to remove dust, the second driving device drives the filter screen 70 to move between a position completely shielding the air inlet and a position far away from the air inlet; and rotates the roller brush 61. When the filter screen 70 removes dust, the filter screen 70 moves from a position at least where the air inlet is completely shielded to a position far away from the air inlet. Preferably, the filter screen 70 is repeatedly opened and closed three times.
By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
