Abstract

The invention discloses a filter screen cleaning reminding device of an indoor unit of an air conditioner and a control method. The filter screen cleaning reminding device of the indoor unit of the air conditioner comprises a filter screen, a first dust sensor, a second dust sensor and a reminder. The first dust sensor and the second dust sensor are arranged on the filter screen in a spaced mode. The reminder is connected with the first dust sensor and the second dust sensor. When dust accumulated on the filter screen reaches the degree that the dust needs to be cleaned up, the first dust sensor and the second dust sensor are connected through the dust on the filter screen, and the reminder reminds users; when the dust on the filter screen does not need to be cleaned up, the first dust sensor and the second dust sensor are disconnected, and the reminder does not remind the users. The filter screen cleaning reminding device of the indoor unit of the air conditioner directly detects the dust on the filter screen, and has the advantages of being accurate and efficient in reminding, small in error judgment probability and the like.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to a filter screen cleaning reminding device of an air conditioner indoor unit and a control method for the filter screen cleaning reminder of the air conditioner indoor unit. Background technique [0002] At present, most air conditioners do not have a filter screen cleaning reminder function, and users can only clean the filter screen with reference to the cleaning stickers attached to the housing of the air conditioner indoor unit. However, due to the different installation locations and environments of the air conditioner, the cleaning cycle and frequency will also be different. For example, if the air conditioner is installed in a large mining plant, or a flour mill, or a food factory, due to the special installation environment, it may run for 3-5 days The air filter is already covered with dust, which affects the cooling and heating effect of the air conditioner. If the air con...
