Background

The dehumidifier is used for pumping away moisture in air in a refrigeration mode to reduce the humidity of the air, keeping the relatively proper humidity of a space, preventing damp and mildewing of articles, household articles and the like which are easy to damp, or manufacturing, producing and storing products, medicines and the like which have high requirements on the humidity in a site within the required humidity range. An existing dehumidifier generally includes a heat exchanger, a water pan, a water tank, and a base pan. The existing dehumidifier mostly adopts a side wall type water tank, the outer side of the water tank is used as one part of the outer side wall of the dehumidifier, and the bottom of the water tank and a chassis form a sliding groove for matching, so that the water tank is conveniently pushed and positioned.

When the dehumidifier works, condensed water on the heat exchanger flows to a water receiving tray below and then flows into a water tank below through a drainage hole on the water receiving tray, and when the water tank is full of water, the sensing device acts to prompt a user to pour water. When a user takes out the water tank and pours water, the heat exchanger fin adsorbs a small amount of water, and meanwhile, a part of accumulated water exists in the water receiving tray, so that the water discharging hole needs to be blocked; otherwise, residual water flows to the chassis from the drainage holes, and the water is accumulated on the chassis more and flows to the ground in the past, so that the use of a user is influenced. Therefore, a drainage flow stopping device is needed to be arranged between the water receiving tray and the water tank, and when the dehumidifier works normally, accumulated water on the water receiving tray is drained into the water tank below the water receiving tray through the drainage hole; when the water tank is taken out and water is poured, the water discharge hole on the water receiving tray is blocked to stop the flow.
