A control method for an air conditioner indoor unit and a fresh air device thereof

Abstract

An air conditioner indoor unit (100) and a control method for a fresh air device thereof. The fresh air device (120) is provided at one side of the indoor unit (100) to supply fresh air to the indoor. The fresh air device (120) is internally mounted with a purification device. The control method comprises: starting the indoor unit (100) to operate (S102); acquiring indoor air quality value (S104); determining whether the indoor air quality value is greater than an air quality threshold (S106); if yes, starting the fresh air device (120) to carry out fresh air exchange (S108); acquiring the air quality value of outdoor fresh air to match a preconfigured cleaning procedure of the fresh air device (120) (S112), wherein a matching condition stipulates air quality value ranges of indoor fresh air corresponding to cleaning procedures; determining and starting, according to the matched result, a cleaning procedure corresponding to the purification device (S114). The present application provides cleaning procedures corresponding to the purification device to prompt in different stages a user to carry out different cleaning procedures so as to ensure the fresh air device (120) to constantly supply to the indoor outdoor air having good air indexes.

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. Quality of life of users. [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
