Problems solved by technology

The current ecological environment is deteriorating. In the indoor home environment, the air usually contains a lot of fine dust. After the air conditioner is turned on, it passes through the filter under the drive of the airflow and is enriched on the surface of the filter. When the amount of fine dust accumulated is large , will block the airflow channel of the filter, affecting the actual performance of the air conditioner; at the same time, the accumulation of dust will easily lead to the growth of bacteria. After the bacteria float in the indoor space with the airflow, it will seriously affect human health.

Embodiment 1

[0047] Such as figure 1 As shown, a filter dust removal reminding method, the resistance strain gauge 2 is arranged on the limit buckle of the filter net, the contact pressure of the limit buckle is related to the degree of dirt and blockage of the filter net, so by obtaining the limit buckle The resistance value of the resistance strain gauge 2 can be used to judge the degree of dirt and blockage of the filter screen, and send a reminder to the user, including:

[0048]Step S1, when the filter screen is cleaned, the resistance value of the corresponding resistance strain gauge 2 is R a , when the air conditioner leaves the factory, R a Stored in the air conditioner as a built-in value.

[0049] In order to give a clear reminder of the degree of dirty blockage, the degree of dirty blockage of the filter screen can be divided into four levels: clean filter screen, slightly dirty blockage, general dirty blockage, and severe dirty blockage; the corresponding resistance strain g...

Embodiment 2

[0064] Such as figure 2 As shown, the difference between the filter dust removal reminder method of this embodiment and embodiment 1 is that after the filter is cleaned, the R a , including the following steps:

[0065] Step 1: When the filter screen is clean, the resistance of strain gauge 2 is R a , the corresponding values ​​of the resistance strain gauge resistance values ​​under slight dirty blockage, general dirty blockage, and severe dirty blockage are respectively R b , R c , R d , and there exists R b =0.95R a , R c =0.85R a , R d =0.75R a , the three coefficients here can be adjusted according to the actual situation, and because the contact state between the filter screen and the filter screen limit buckle 1 may change after the filter screen is artificially cleaned, so R a The specific value is determined by the first time the filter is dirty and blocked after the filter is cleaned;

[0066] Step 2: When the resistance strain gauge 2 is disconnected fro...

Embodiment 3

[0079] The present invention also provides a filter dust removal reminding device, which is used to implement the above-mentioned filter dust removal reminding method. The filter dust removal reminding device includes: a resistance strain gauge 2 and a controller, the two are electrically connected, The sheet 2 is arranged on the limit buckle 1 of the filter screen in the middle frame of the air conditioner, and the controller detects the dirty state of the filter screen according to the change of the resistance value of the detection resistance strain sheet 2 .

[0080] Such as Figure 3-4 As shown, it shows the setting position of the limit buckle 1 of the filter screen. The existing air conditioner structure is generally equipped with a limit buckle 1. Its structure is trapezoidal, has good structural strength, and is convenient for the installation of the filter screen. , which is integrally compression-molded with the middle frame of the air conditioner during processing....

Abstract

The invention relates to a filter screen dust removal reminding method and device and an air conditioner. The filth blockage state of a filter screen is reflected by monitoring the resistance value change of a resistance strain gauge. When filth blockage of the filter screen reaches a certain degree, dust removal reminding is conducted. By comparing the resistance value Ri of the resistance straingauge in the normal work state with the resistance value Ra of the resistance strain gauge obtained after the filter screen is cleaned, whether the resistance strain gauge is in the normal work stateor not is identified, so that the filth blockage state of the filter screen can be reflected. The reflection and reminding effects are good. According to the scheme, the structure of an existing airconditioner is not changed, only the resistance strain gauge needs to be arranged on the filter screen and a filter screen limiting buckle of a middle frame, and the technical effects that the technical universality is high and later overhauling and maintaining are simple are achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a filter dust removal reminder method, a reminder device and an air conditioner. Background technique [0002] With the development of modern society, the living standard of residents is getting higher and higher, and people pay more and more attention to the home environment and their own health. The current ecological environment is deteriorating. In the indoor home environment, the air usually contains a lot of fine dust. After the air conditioner is turned on, it passes through the filter under the drive of the airflow and is enriched on the surface of the filter. When the amount of fine dust accumulated is large , will block the airflow channel of the filter, affecting the actual performance of the air conditioner; at the same time, the enrichment of dust will easily lead to the growth of bacteria. After the bacteria float in the indoor space with the airflow, it wi...
