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] like figure 1 As shown, a filter dust removal reminding method, a strain gauge 2 is arranged on the limit buckle of the filter, and the contact pressure of the limit buckle is related to the degree of dirt and blockage of the filter net. 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 gauge 2 resistance Values ​​are R a , R b , R ...

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 net dedusting reminding method, a reminding device and an air conditioner, which reflects the dirty and clogged state of the filter net by monitoring the resistance value change of the resistance strain gauge, and when the filter net is dirty and clogged to a certain degree, the dust removal reminder is carried out by The resistance value R of the resistance strain gauge under normal working conditions i The resistance value R of the resistance strain gauge after the cleaning operation with the filter a For comparison, identify whether it is working normally and distinguish the dirty and clogged state of the filter screen, which has a good distinction and prompt effect, and this scheme does not change the existing structure of the air conditioner, only the filter screen and the filter screen limit card of the middle frame Just buckle up and arrange resistance strain gauges, which has the technical effect of strong technical versatility and simple later inspection and maintenance.

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...
