Air conditioner indoor unit, and control method of fresh air device of air conditioner indoor unit

Abstract

The invention provides an air conditioner indoor unit, and a control method of a fresh air device of the air conditioner indoor unit. One side of the indoor unit is provided with the fresh air deviceused for delivering outdoor fresh air into a room; and the fresh air device is internally provided with a purification device. The control method comprises the steps of turning on the indoor unit to operate; acquiring an indoor air quality value; judging whether the indoor air quality value is larger than an air quality threshold; turning on the fresh air device to exchange fresh air if yes; acquiring an outdoor fresh air quality value; matching the outdoor fresh air quality value with preset cleanup programs of the fresh air device; providing the indoor fresh air quality value range corresponding to the cleanup programs specified by the matching conditions; and determining and starting the cleanup programs corresponding to the purification device according to the matching results. Thus, the invention provides the cleanup programs corresponding to the purification device, and a user is alerted to perform different cleanup programs in different stages, so that the fresh air device is ensured to deliver outdoor air with an excellent air quality index incessantly.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to an air conditioner indoor unit and a control method for fresh air replacement thereof. Background technique [0002] An air conditioner is a widely used household appliance. It generally has heating and cooling functions. When the ambient temperature is too low or too high, it can adjust the temperature of the indoor air to provide users with a suitable indoor environment and effectively improve the air conditioner.

[0003] However, because the current air conditioners only circulate the indoor air to heat or cool down when heating or cooling, and the user will close the door of the living room at the same time in order to maintain the indoor temperature, so that the indoor air quality will be reduced. It will gradually deteriorate, which will adversely affect the user's health. In particular, in recent years, air pollution has been increasing...

AI Technical Summary

Problems solved by technology

[0004] After the fresh air device is introduced into the current indoor unit of the air conditioner, when the fresh air function is used, the amount of air for heat exchange will be increased. Under the premise that the heating capacity of the air conditioner remains unchanged, it will take longer for the air conditioner to reach the temperature set by the user. , will make the heating effect worse, thus affecting the user experience
