Problems solved by technology

The accumulated dirt inside the air conditioner may corrode the internal components of the air conditioner, and the coverage of dust (bacteria, mold, etc.) will weaken the heat dissipation effect of the air conditioner components, affect the health of users, and make the user experience worse. It is very important to maintain the air conditioner in time
At present, air conditioner users often do not and cannot take the initiative to understand the cleanliness of the air conditioner, so they cannot clean the dirty inside of the air conditioner in a timely manner, resulting in the degree of dirty inside the air conditioner that has been used for a long time is gradually serious, and the operation of the air conditioner is getting worse. worse
[0003] Most of the existing methods for detecting the cleanliness of the air conditioner are to judge the cleanliness by calculating the operating time of the air conditioner, but environmental factors will cause this method to be inaccurate. Check the cleanliness of the air conditioner. Installing these devices inside the air conditioner will not only increase the cost, but once damaged, it will greatly increase the difficulty of later maintenance

Embodiment 1

[0064] figure 1 It is a schematic flowchart of Embodiment 1 of the method for detecting the cleanliness degree of an air conditioner indoor unit shown in the embodiment of the present application.

[0065] see figure 1 , Embodiment 1 of the method for detecting the cleanliness of the air-conditioning internal unit in the embodiment of the present application includes:

[0066] 101. Control the air conditioner to run for a preset time in the laboratory environment;

[0067] The laboratory is a dust-free laboratory to avoid the interference of measurement and calculation data by dust and other impurities.

[0068] 102. Measure the indoor temperature of the laboratory after the preset time, and calculate the rate of change of the indoor temperature of the laboratory within the preset time to obtain the reference temperature rate of change;

[0069] 103. Control the air conditioner to run for a preset time in actual usage scenarios;

[0070] The preset times to control the ope...

Embodiment 2

[0077] In practical applications, on the basis of the first embodiment, this embodiment specifically introduces how to calculate the reference temperature change rate.

[0078] figure 2 It is a schematic flowchart of Embodiment 2 of the method for detecting the cleanliness degree of an air conditioner indoor unit shown in the embodiment of the present application.

[0079] see figure 2 , Embodiment 2 of the method for detecting the cleanliness of the air-conditioning internal unit in the embodiment of the present application includes:

[0080] 201. Measure the indoor temperature of the laboratory after the preset time to obtain the first termination temperature;

[0081] 202. Use the difference of the preset temperature minus the first end temperature, and divide it by the preset time to obtain the base temperature change rate.

[0082] The laboratory environment also includes: the indoor temperature of the laboratory before the preset time is the preset temperature, the ...

Embodiment 3

[0088] In practical applications, on the basis of the above embodiments, this embodiment introduces in detail how to judge the cleanliness of the air conditioner internal unit according to the deviation between the actual temperature change rate and the reference temperature change rate.

[0089] image 3 It is a schematic flow chart of Embodiment 3 of the method for detecting the cleanliness degree of an air conditioner indoor unit shown in the embodiment of the present application.

[0090] see image 3 , the third embodiment of the method for detecting the cleanliness of the air-conditioning internal unit in the embodiment of the present application includes:

[0091] 301. Set the actual temperature change rate R2 and the reference temperature change rate R1, then the temperature change rate deviation is

[0092] 302. Calculate the cleanliness degree of the air conditioner inner unit according to the deviation value K of the temperature change rate as U=(1-K)*100%.

Abstract

The invention relates to an air conditioner indoor unit cleanliness degree detection method and an air conditioner thereof. The method comprises the steps that the air conditioner is controlled to run in a laboratory environment for preset time; measuring the indoor temperature of the laboratory after the preset time, and calculating the change rate of the indoor temperature of the laboratory within the preset time to obtain a reference temperature change rate; the air conditioner is controlled to run for the preset time in the actual use scene; the indoor temperature in the actual use scene after the preset time is measured, the change rate of the indoor temperature in the actual use scene within the preset time is calculated, and the change rate of the actual temperature is obtained; and according to the deviation between the actual temperature change rate and the reference temperature change rate, the cleanliness degree of the air conditioner indoor unit is judged. According to the scheme provided by the invention, the cleanliness degree of the air conditioner indoor unit can be accurately judged under the condition that an air conditioner internal detection device is not additionally arranged.

Description

technical field [0001] The present application relates to the technical field of air conditioners, in particular to a method for detecting the cleanliness of an air conditioner inner unit and the air conditioner. Background technique [0002] The cleanliness of the air conditioner is closely related to the service life and quality of the air conditioner. The accumulated dirt inside the air conditioner may corrode the internal components of the air conditioner, and the coverage of dust (bacteria, mold, etc.) will weaken the heat dissipation effect of the air conditioner components, affect the health of users, and make the user experience worse. It is very important to maintain the air conditioner in time. At present, air conditioner users often do not and cannot take the initiative to understand the cleanliness of the air conditioner, so they cannot clean the dirty inside of the air conditioner in a timely manner, resulting in the degree of dirty inside the air conditioner th...
