Method for controlling self-cleaning and drying of air conditioner, indoor unit of air conditioner and storage medium

Abstract

The invention provides a method for controlling self-cleaning and drying of an air conditioner, an air conditioner indoor unit and a storage medium. The method of controlling the self-cleaning and drying of the air conditioner includes: detecting the self-cleaning and drying instruction, controlling the air conditioner to run in the heating mode; controlling the electronic throttle of any one of the multiple indoor heat exchange components to the first drying Dry protection opening, and control the suspension of the indoor fan of any indoor heat exchange component, and control the electronic throttling parts of other indoor heat exchange components except any indoor heat exchange component to the first Two drying protection openings, wherein, the second drying protection opening is greater than the first drying protection opening; the temperature of the indoor heat exchanger of any indoor heat exchange component reaches the sterilization temperature, and the cumulative drying time reaches the preset drying time. The method can realize effective sterilization, and can avoid the overload protection of the indoor heat exchanger due to excessive temperature.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for controlling self-cleaning and drying of an air conditioner, a non-temporary computer storage medium and an air conditioner indoor unit. Background technique [0002] Most of the air conditioners currently on the market have a self-cleaning function. The fins of the heat exchanger are cleaned by using condensed water. However, some water stains and stains will be left after cleaning in this way. If accumulated for a long time, it will cause Bacteria overgrow on the fins and produce peculiar smell, and enter the room with the air-conditioning wind. In order to avoid this situation, most air conditioners will use the heating function to dry the self-cleaning fins. Since the bacteria can be effectively sterilized in an environment of 56°C for more than 30 minutes, when using refrigerant heating to dry the heat exchanger, the fan motor should run at low power, th...

[0002] Most of the air conditioners currently on the market have a self-cleaning function. The fins of the heat exchanger are cleaned by using condensed water. However, some water stains and stains will be left after cleaning in this way. If accumulated for a long time, it will cause Bacteria overgrow on the fins and produce peculiar smell, and enter the room with the air-conditioning wind. In order to avoid this situation, most air conditioners will use the heating function to dry the self-cleaning fins

Since the bacteria can be effectively sterilized in an environment of 56°C for more than 30 minutes, when using refrigerant heating to dry the heat exchanger, the fan motor should run at low power, that is, use low wind flow to dissipate heat from the heat exchanger, so that The heat exchanger will not have overload protection due to excessive temperature, but this method will cause the temperature at the front end of the heat exchanger to reach 56°C, and the temperature of the heat exchanger will gradually decrease along the flow direction of the refrigerant, and cannot reach 56°C. Standard, and if it runs for a long time, it will also increase the risk of heat exchanger overload protection, resulting in the sterilization process not being able to maintain more than 30 minutes
