Specifically, as shown in fig. 3, when the indoor unit of the air conditioner is in a cooling (or heating) mode, the return air plate 223 is at an initial position, the air deflector 21 is opened to a predetermined angle, and when the fan is operated, air is blown out from the air supply duct, so that normal cooling or heating can be achieved; when the ion generator is turned on, ions are released and are brought out of the air-conditioning indoor unit by wind, namely, the air-conditioning indoor unit is indoor, and the indoor air is subjected to ion sterilization to realize air purification.
Specifically, the air conditioner in the prior art has a large concentration of odor due to the propagation of bacteria and microorganisms, and the odor is easily blown into a room when the air conditioner is started. When the indoor air conditioner is started or does not refrigerate or heat, the indoor air conditioner can be in a return air circulation sterilization state firstly, as shown in fig. 1, when the indoor air conditioner is in a sterilization mode, the air deflector 21 is in the first position, the return air plate 223 is in the return air position, the fan 70 is opened, the air current passes through the air supply duct 11, the fan 70, the return air duct 30, the air supply duct 11 and the fan 70 at the moment, the circulating air current is simultaneously started, released ions return to the return air duct 30 along with the air current, then enter the inside of the shell assembly through the evaporator (namely, the heat exchanger 50) to sterilize and purify the ions inside the indoor air conditioner, and after the air current inside the air conditioner circulates for multiple times, the air conditioner can be switched to a refrigeration and heating state, and clean air current is blown out.
During specific implementation, in a sterilization mode, if the wind speed is too high, the airflow is difficult to fully react with structures containing a large amount of bacteria, such as an evaporator (namely a heat exchanger) and a water pan of the indoor unit of the air conditioner, so that the rotating speed of the fan is relatively low, the ion wind fully flows through the air conditioner in a large area, the airflow can be fully contacted with parts, such as the water pan and the evaporator, of the indoor unit of the air conditioner, which are easy to wet, the sterilization efficiency is increased, and the optimal sterilization effect is achieved.
In one embodiment, the air conditioning indoor unit is a wall-mounted unit.
In particular, one of the main reasons causing the air conditioner to generate the peculiar smell is that the inside of the air conditioner is polluted and bacteria are bred, so that the musty smell is generated. The technical problem that this application solved is: the problem that the peculiar smell generated by the microorganism in the air conditioner is dispersed by the air blowing of the air conditioner; the ion sterilization effect is poor; ion sterilization is limited to killing bacteria in the indoor air outside the air conditioner.
The beneficial effect of this application does: no peculiar smell generated by air-conditioning microorganisms is emitted when the air conditioner is started; the ion generator does not influence normal air outlet; the air conditioner can circularly kill bacteria bred in the air conditioner and bacteria outside the air conditioner (in indoor air) for multiple times, and omnibearing sterilization is realized.
From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects:
the air-conditioning indoor unit has a sterilization mode, when the air-conditioning indoor unit is in the sterilization mode, the panel component 20 and the air deflector 21 jointly form a return air duct 30, one end of the return air duct 30 is communicated with the first air outlet 112, and the other end of the return air duct 30 is communicated with the air supply duct 11 through the return air inlet 32, so that air flowing out of the first air outlet 112 flows back to the air supply duct 11 through the return air duct 30, and the air circularly flows between the air supply duct 11 and the return air duct 30; moreover, the air drives the sterilizing substances to flow together after passing through the sterilizing device 40 in the air supply duct 11, so that the circulating flow process is used for sterilizing various flowing structures, the sterilizing effect is good, the bacteria breeding in the indoor unit of the air conditioner can be killed, and the problem that the peculiar smell generated by microorganisms in the air conditioner is blown out through the air conditioner is solved.
