In a first embodiment, the air conditioning control method includes:
step S10, after receiving the cleaning instruction, acquiring the dew point temperature of the current indoor air;
when the indoor unit needs cleaning, a cleaning instruction is sent to the air conditioner; the cleaning instruction can be sent to the air conditioner by a user through an air conditioner remote controller, or can be generated at regular time when the air conditioner runs, or the air conditioner automatically generates according to the fact that the heat exchange efficiency of the evaporator is lower than a preset value. The dew point temperature is a critical temperature at which water vapor in the air is exposed to dew, that is, the air temperature is condensed into water drops when being lower than the dew point temperature. The dew point temperature of the current indoor air can be obtained in various ways, for example: 1. detecting the temperature and humidity of indoor air, and then checking a prestored mapping table according to the detected temperature and humidity to obtain dew point temperature, or obtaining corresponding dew point temperature according to the detected temperature and humidity through a preset calculation formula; 2. detected by a dew point temperature measuring instrument.
Step S20, controlling the air conditioner to run in a refrigerating mode so that the temperature in the indoor unit is lower than the acquired dew point temperature; the control of the air conditioner refrigeration operation is carried out when an air outlet of the indoor unit is in a closed state.
Controlling the air conditioner to set a set temperature value lower than the acquired dew point temperature according to the acquired dew point temperature to perform refrigeration operation; since the air conditioner is to cool the inside of the indoor unit to reduce the temperature of the inside of the indoor unit to be lower than the acquired dew point temperature, the operation of controlling the cooling operation of the air conditioner is performed based on the air outlet of the indoor unit being in a closed state. The closing of the air outlet can be that the air conditioner controls the air outlet to be closed after receiving a cleaning instruction (if the air outlet is in a closed state at the beginning, the air conditioner does not act on the air outlet to keep the air outlet in the closed state); the operation of closing the outlet may be performed before/after the dew point temperature of the current indoor air is acquired. When the air outlet is closed, the air conditioner performs refrigeration operation to enable the refrigerated air flow to perform vortex circulation in the indoor unit to cool the interior of the indoor unit until the temperature in the indoor unit is lower than the acquired dew point temperature. When the temperature in the indoor unit is lower than the acquired dew point temperature, water vapor in the air in the indoor unit is combined with dust on components (including an evaporator and other components) of the indoor unit and condensed into water drops, and the water drops formed by combining with the dust drop into a water receiving tray or a water storage tank of the indoor unit and are discharged through a water discharge pipe of the indoor unit.
According to the air conditioner control method provided by the embodiment, the indoor unit is controlled to perform cooling operation until the temperature of the indoor unit is lower than the dew point temperature of air when the air outlet is closed, so that the air in the indoor unit is condensed into water drops to take away dust on the evaporator and then the water drops onto the water receiving tray to form sewage, and the sewage is discharged through the drain pipe, so that the self-cleaning of the indoor unit of the air conditioner is completed, and the air conditioner is very convenient.
Referring to fig. 2, fig. 2 is a flowchart illustrating an air conditioning control method according to a second embodiment of the present invention.
This embodiment is based on the solution of the first embodiment, and in the second embodiment, after step S20, the air conditioner control method further includes:
step S30, controlling the heating operation of the air conditioner;
after step S20, the outlet is still closed, that is, the heating operation is performed with the outlet closed. After the dust on the evaporator is taken away by the condensation in the indoor unit, the air conditioner is heated to raise the temperature inside the indoor unit for drying, so that the moisture in the dust left in the indoor unit is evaporated to form a block shape so as to fall off by vibration.
Step S40, after the air conditioner continuously heats for a preset first time, controlling the air conditioner to switch the running state within a preset second time;
a user can set corresponding first time length according to the required drying degree in the indoor unit; after the interior of the indoor unit is dried, residual dust forms lumps, the air conditioner is controlled to switch the operation state so that the refrigerant impacts an evaporator of the indoor unit, the evaporator vibrates to drop the residual dust, the duration (namely the second duration) is set according to the user requirement, and the frequency of the operation state switching of the air conditioner can be selected on the premise that the vibration strength does not influence the performance of the evaporator and cause damage. Specifically, the scheme for switching the operating state of the air conditioner in this embodiment may be preferably scheme 1: controlling the switching of the conduction direction of a four-way valve of the air conditioner, and enabling a refrigerant in a copper pipe to impact a pipeline to form evaporator vibration by changing the direction of the four-way valve even if the air conditioner is switched between a cooling operation state and a heating operation state; preferred embodiment 2: the switching of the operating frequency of the air-conditioning compressor is controlled, and when the compressor is switched between two or more frequencies, the change of the operating frequency of the compressor can also cause the refrigerant to impact the copper pipe to form the vibration of the evaporator. Of course, the switching scheme for controlling the operation state of the air conditioner may be implemented in other manners.
And step S50, controlling the air conditioner to perform cooling operation so that the temperature in the indoor unit is lower than the acquired dew point temperature.
After the vibration operation of the evaporator is finished, the shaken dust needs to be taken out of the indoor unit, the air conditioner is controlled to perform refrigerating operation again (the refrigerating operation is still performed when the air outlet of the indoor unit is in a closed state), the temperature in the indoor unit is reduced until the temperature in the indoor unit is refrigerated to be lower than the obtained dew point temperature, condensed water drops are formed in the indoor unit again, the condensed water drops further clean the evaporator, the shaken dust is melted into water flow, and the water flow is discharged from the water discharge pipe, so that the more thorough cleaning of the outdoor unit of the air conditioner is completed.
According to the air conditioner control method, vibration is generated by heating and drying the interior of the indoor unit and switching the operation state, residual dust on the evaporator is shaken off, water drops are formed by refrigeration again to form secondary cleaning, and the dust with shaking off is taken to be discharged from the drain pipe, so that the evaporator of the indoor unit is cleaned more thoroughly.
Referring to fig. 3, fig. 3 is a flowchart illustrating a control method of an air conditioner according to a third embodiment of the present invention.
This embodiment is based on the solution of the first embodiment or the second embodiment, and in the third embodiment, before step S10, the air conditioner control method further includes:
step S60, acquiring the opening and closing state of the air outlet;
because the interior of the indoor unit needs to be cooled, and the air outlet of the indoor unit needs to be closed to realize the post-processing operation, the opening and closing state of the air outlet needs to be confirmed after a cleaning instruction is received. The opening and closing state of the air outlet can be confirmed by acquiring the state of a driving motor for driving the air deflector or the corresponding control potential on the controller. It should be noted that, the steps of obtaining the opening and closing state of the air outlet and obtaining the dew point temperature of the current indoor air are not in sequence, that is, obtaining the opening and closing state of the air outlet may be performed before obtaining the dew point temperature of the current indoor air, or may be performed after obtaining the dew point temperature of the current indoor air.
And step S70, controlling the air outlet to be closed when the air outlet is in an open state.
When the air outlet is in an opening state, the air outlet is controlled to be closed, and the air outlet is driven to be closed by sending an instruction to a controller of the air deflector driving motor or directly sending an instruction to the driving motor. When the air outlet is in a closed state, the operation is not performed, or the step S10 is directly skipped.
According to the air conditioner control method, the air conditioner can automatically detect and close the air outlet through the above mode, so that the cleaning operation of the indoor unit can be executed, the cleaning operation of the indoor unit can be triggered without manually closing the air outlet, and the air conditioner control method is more convenient.
