Dehumidifier air valve control method and dehumidifier

Abstract

The invention relates to the technical field of household electric appliances and discloses a dehumidifier air valve control method and a dehumidifier. The dehumidifier air valve control method comprises the steps of detecting the carbon dioxide content and the formaldehyde content inside a room in real time; and according to the detected carbon dioxide content and the formaldehyde content, controlling working states of an air return valve, a fresh air valve and an exhaust fan so that the dehumidifier can be switched into a different working mode. The carbon dioxide content and the formaldehyde content inside the room are detected in real time, the working states of the air return valve, the fresh air valve and the exhaust fan are controlled according to the carbon dioxide content and theformaldehyde content so that working modes of the dehumidifier can be switched, and thus, the air return amount and the fresh air amount inside the room can be controlled; furthermore, the carbon dioxide content and the formaldehyde content inside the room can be controlled so that it can be guaranteed that the carbon dioxide content and the formaldehyde content, formed after dehumidification, inside the room are within the normal range; and therefore, health of users is effectively prevented from being affected.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to a method for controlling an air valve of a dehumidifier and the dehumidifier. Background technique [0002] A dehumidifier is an electrical appliance used to remove moisture from the air. It draws the humid air into the machine through a fan, and then condenses the water molecules in the air into water droplets through a heat exchanger. The air is exhausted outside the machine and circulated in this way, so that the humidity of the environment is kept at a suitable relative humidity. In addition, the dehumidifier can not only effectively improve the humid living and production environment, but also remove the mold and suspended particles in the air brought by the humid environment, thereby creating a comfortable and dry space for people. [0003] At present, the design of existing dehumidifiers generally adopts the method of separating the fresh air chann...
