Self-cleaning control method for air conditioner

Abstract

The invention belongs to the technical field of air conditioners, and aims to solve the problem that due to judgment of an existing air conditioner according to a single condition of an outdoor unit draught fan current, a self-cleaning mode is frequently executed by misjudgment of the air conditioner. Therefore, the invention provides a self-cleaning control method for the air conditioner, the self-cleaning control method comprises the following steps that when the air conditioner refrigerates, a coil pipe temperature of an indoor unit, a dew point temperature of air, an average value of current-month electric current of the indoor unit, the average value of last-moon electric current and the average value of the month before the last-moon electric current, the electric value of the current month setting moment and the electric current value of the last month setting moment are acquired; a first attenuation value, a second attenuation value, a third attenuation value and a fourth attenuation value are correspondingly calculated; and whether the self-cleaning mode is executed to the indoor unit or not is judged according to the coil pipe temperature of the indoor unit, the dew pointtemperature of the air, the first attenuation value, the second attenuation value, the third attenuation value and the fourth attenuation value. According to the method, the air conditioner can execute the self-cleaning mode under a reasonable condition.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides a self-cleaning control method for an air conditioner. Background technique [0002] The air conditioner is a device that can cool / heat the room. As time goes by, the dust accumulation on the indoor and outdoor units of the air conditioner will gradually increase. After the dust accumulation reaches a certain level, a large number of bacteria will grow, especially in the indoor When the air flows through the indoor unit, it will carry a lot of dust and bacteria, so the air conditioner needs to be cleaned in time. [0003] In the prior art, the cleaning methods of the air conditioner include manual cleaning and self-cleaning of the air conditioner. It is time-consuming and labor-intensive to use manual cleaning. It is necessary to disassemble the various parts of the air conditioner and then clean them. After cleaning, each part needs to be reinstalled. Assemble...

Problems solved by technology

[0005] In order to solve the above problems in the prior art, that is, in order to solve the problem that the existing air conditioner passes the judgment of the single condition of the fan current of the indoor unit, it is easy to cause the air conditioner to frequently execute the self-cleaning mode due to misjudgment, the present invention provides a A self-cleaning control method for an air conditioner, the air conditioner includes an indoor unit, the self-cleaning control method includes: when the air conditioner is in cooling operation, obtaining the coil temperature of the indoor unit, the dew point temperature of the air, and the fan current of the indoor unit for the current month Average value, average value of fan current in the last month, average value of fan current in the previous month, current value at the setting time of the current month and current value at the setting time of the previous month; calculate the average value of the fan current of the current month relative to the fan current value of the previous month The first attenuation value of the current average value; calculate the second attenuation value of the fan current average value of the previous month relative to the fan current average value of the previous month; calculate the current value at the set time of the current month relative to the fan current average value of the previous month The third attenuation value; calculate the fourth attenuation value of the current value at the set moment of the previous month relative to the fan current average value of the previous month; according to the coil temperature of the indoor unit, the dew point temperature of the air, the first attenuation value, the second The second attenuation value, the third attenuation value and the fourth attenuation value, determine whether to implement self-cleaning mode for the indoor unit
