Problems solved by technology
The dirt adheres to the heat exchanger of the indoor unit. On the one hand, it will reduce the heat transfer performance of the heat exchanger, resulting in a decrease in the performance of the air conditioner and an increase in energy consumption; Bacteria and mildew will produce peculiar smell in the unit, if not cleaned in time, it will seriously threaten the health of air conditioner users
[0003] The solution adopted by traditional air conditioners is generally to clean them regularly, which brings serious inconvenience to users. Therefore, in order to solve the above-mentioned problems caused by the adhesion of dust and dirt

The invention provides an air conditioner with a self-cleaning function and a control method for the air conditioner. An indoor unit of the air conditioner is equipped with an indoor unit fan, an indoor unit heat exchanger, a humidifying assembly and a humidity sensor, wherein the humidifying assembly is provided with a spray hole which is formed in the indoor unit and is positioned at the air inlet upstream of the indoor unit heat exchanger. The control method comprises the following steps of: receiving a trigger that the air conditioner starts a self-cleaning function; controlling the indoor unit heat exchanger to operate in an evaporator mode and closing the indoor unit fan; judging whether humidity, detected by the humidity sensor, of an indoor unit working environment is lower than a preset temperature threshold value or not, starting the humidifying assembly if the humidity is lower than the preset temperature threshold value, spraying out water mists through the spray hole, and improving frosting degree at the indoor unit heat exchanger; and after determining that the indoor unit heat exchanger reaches a set defrosting condition, controlling the indoor unit heat exchanger to defrost, and taking away attached pollutants by water formed by defrosting, thereby realizing self-cleaning of the indoor unit heat exchanger. According to the scheme adopted by the invention, the self-cleaning effect is obviously improved.
Description
technical field [0001] The invention relates to a household air conditioner, in particular to an air conditioner with self-cleaning function and a control method thereof. Background technique [0002] After the air conditioner is placed or used for a long time, there will be a lot of dust in the air conditioner. The dust attached to the heat exchanger of the indoor unit will reduce the heat transfer performance of the heat exchanger on the one hand, resulting in a decrease in the performance of the air conditioner and an increase in energy consumption; Bacteria and mildew will produce peculiar smell in the unit, if not cleaned in time, it will seriously threaten the health of air conditioner users. [0003] The solution adopted by traditional air conditioners is generally to clean them regularly, which brings serious inconvenience to users. Therefore, in order to solve the above-mentioned problems caused by the adhesion of dust and dirt on the heat exchanger of the air cond...
