Problems solved by technology
[0002] When the air conditioner is running for a long time, there will inevitably be impurities and bacteria on the indoor heat exchanger. These impurities will adhere to the indoor heat exchanger. These bacteria and mildew will cause peculiar smell in the unit, and when the air conditioner is blowing air, impurities and bacteria will easily enter the room, affecting the user's respiratory health

Embodiment Construction
[0033] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0034] refer to figure 1 , an embodiment of the present invention provides a self-cleaning control method for an air conditioner indoor unit, the method comprising the following steps:
[0035] S01 enters the cooling mode, in which the operating frequency of the compressor is controlled to make the indoor heat exchanger frost;
[0036] And the relationship between the current outdoor ambient temperature T and the operating frequency f of the compressor is as follows:
[0037] When the outdoor ambient temperature T≥55℃: 50HZ≤f≤75HZ;
[0038] When the outdoor ambient temperature is 35℃≤T<55℃: 45HZ≤f≤60HZ;
[0039] When the outdoor ambient temperature is 15℃≤T<35℃: 30HZ≤f...

The invention relates to the technical field of air conditioners, in particular to a self-cleaning control method for an air conditioner indoor unit. The method comprises the steps of entering a refrigeration mode; in the refrigeration mode, controlling the operation frequency of a compressor, and enabling an indoor heat exchanger to be frosted; entering a heating mode after the temperature of theindoor heat exchanger is lower than a first preset temperature and lasts for a first preset time and the surface of the indoor heat exchanger is frosted to form a certain thickness; and in the heating mode, controlling the running frequency of the compressor, enabling the temperature of the indoor heat exchanger to be higher than a second preset temperature, enabling the surface of the indoor heat exchanger to be rapidly defrosted to form a water flow so as to flush the surface of the indoor heat exchanger, completely melting frosting after lasting for a second preset time, and entering a standby state, so that self-cleaning of the indoor heat exchanger is achieved. According to the self-cleaning control method for the air conditioner indoor unit provided by the invention, impurities andbacteria attached to the indoor heat exchanger are removed under the condition that other parts are not added on the basis of a traditional air conditioner, an automatic cleaning effect of the indoorheat exchanger is achieved, and the use safety of a user is guaranteed.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a self-cleaning control method for an air conditioner indoor unit. Background technique [0002] When the air conditioner is running for a long time, there will inevitably be impurities and bacteria on the indoor heat exchanger. These impurities will adhere to the indoor heat exchanger. These bacteria and mildew will cause peculiar smell in the unit, and when the air conditioner is blowing air, impurities and bacteria will easily enter the room, affecting the user's respiratory health. Contents of the invention [0003] The purpose of the present invention is to provide a self-cleaning control method for an air-conditioning indoor unit without adding parts, realize clear impurities and bacteria attached to the internal heat exchanger, and improve user safety. [0004] In order to achieve the above object, the present invention provides a self-cleaning control method o...
