Abstract
The invention discloses an air conditioner self-cleaning control method based on humidity detection, and relates to the technical field of air conditioner control.
Description
Technical Field
The invention belongs to the technical field of air conditioner control, and particularly relates to an air conditioner self-cleaning control method based on humidity detection.
Background
After the air conditioner used for a long time, if not in time clean, can save more and more dirty thing in the heat exchanger, again because present air quality is relatively poor, the stifled condition of dirtiness of air conditioner heat exchanger is also more and more serious, can cause huge threat to human health, current air conditioner self-cleaning function is when the operation, because the indoor environment of air conditioner place difference, the difference of indoor environment humidity, lead to the heat exchanger frosting thickness not enough, the volume of condensation is not enough, can increase the time of automatically cleaning operation, can lead to indoor temperature fluctuation big, also can influence the effect of air conditioner automatically cleaning simultaneously, cause user experience not good.
Disclosure of Invention
In view of the above-mentioned drawbacks of the prior art, the technical problem to be solved by the present invention is to provide a method for increasing the amount of condensed water at the beginning of self-cleaning.
In order to achieve the purpose, the invention provides an air conditioner self-cleaning control method based on humidity detection.
Preferably, when the RH is more than or equal to 75 percent, the inner fan stops after running for t minutes, and t is more than 0; when the RH is more than 75% and more than or equal to 60%, the inner fan stops after t +1 min of operation, and t is more than 0; when the RH is more than or equal to 40% and more than or equal to 60%, the inner fan stops after t +2 minutes of operation, and t is more than 0; when the RH is less than 40%, the internal fan is stopped after t +4 minutes, and t is more than 0.
Preferably, the inner fan is operated in a silent mode, and the rotation speed per minute of the inner fan of the air conditioner is 600-650 revolutions.
The invention has the beneficial effects that: the invention can synchronously detect the indoor environment humidity when the air conditioner carries out self-cleaning, and controls the running time of the fan in the air conditioner according to the difference of the indoor environment humidity. The invention can ensure sufficient condensation water amount at the self-cleaning starting stage, reduce self-cleaning time, reduce temperature fluctuation and improve user experience.
Drawings
FIG. 1 is a schematic flow chart of an embodiment of the present invention.
Detailed Description
The invention is further illustrated by the following examples in conjunction with the accompanying drawings:
as shown in fig. 1, a humidity detection-based air conditioner self-cleaning control method detects indoor environment humidity RH by adding a humidity sensor to an air conditioner indoor unit, and controls operation time of an inner fan during self-cleaning frosting according to that the indoor environment humidity RH is in different intervals.
In the embodiment, when the RH is more than or equal to 75%, the operation of the inner fan is stopped after 3 minutes, and the heat exchanger frosts; when the RH is more than 75% and is more than or equal to 60%, the operation of the inner fan is stopped after 4 minutes, and the heat exchanger frosts; when the RH is more than or equal to 40% and more than or equal to 60%, the operation of the inner fan is stopped after 5 minutes, and the heat exchanger frosts; when the RH is less than 40 percent, the internal fan is stopped after running for 7 minutes, and the heat exchanger frosts.
In this embodiment, the inner fan operates in a silent mode; the rotating speed per minute of the air conditioner internal fan is 620 revolutions when the air conditioner operates in the silent mode.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
