Description

Dehumidifier

Technical Field

The utility model relates to a household electrical appliances field especially relates to a dehumidifier.

Background

The evaporator of dehumidifier contacts with the air and can produces more comdenstion water, and the dehumidifier generally includes water collector and water storage box, and the water collector is located the evaporator under and collects the comdenstion water, and the comdenstion water after collecting can pour into in the water storage box under the water collector. Under normal conditions, a water pump is arranged in the dehumidifier and is communicated with a water pumping port at the bottom of the water storage box through the water pump, so that accumulated water in the water storage box is discharged to the external environment. However, when the water pump or the water pipe of the water pump is blocked, the water pump cannot work normally, and in order to avoid that accumulated water submerges the edge of the water storage box and wets the bottom plate or components inside the dehumidifier, a main drainage hole is generally additionally arranged and communicated with the water tank in the dehumidifier, and the accumulated water higher than the water inlet of the main drainage hole can directly flow into the water tank.

Normally, be equipped with water level monitoring devices in the dehumidifier, detect the height up to standard of water level when water level monitoring devices's float, the water pump will start and carry out the pump drainage with ponding in the water storage box. Therefore, the height of the water inlet of the main drainage hole needs to be higher than the touch water level H3 of the floater (the touch water level H3 of the floater is that after the floater reaches the touch water level, the water pump is started to pump and drain accumulated water at the water pumping hole of the water storage box) so as to ensure that the water pump pumps water to the water storage box as the main mode for draining the water storage box.

However, due to the wide variety of use environments of users, when the floor is uneven, the dehumidifier may tilt a certain angle in any directions of front, back, left and right when placed on the ground (it should be noted that, in the prior art, due to the structure of the whole dehumidifier, the main drainage hole must be formed at the edge of the water storage box and spaced from the float by a certain distance), so that when the dehumidifier tilts in a certain direction, the touch water level H3 of the float may be higher than the water inlet height of the main drainage hole, and at this time, the water pump may not be started normally. When the dehumidifier is inclined to the left and the water storage box is inclined to the left, the floater does not reach the touch water level H3 of the floater, and the liquid level is higher than the water inlet of the main drainage hole, so that the water pump cannot work normally.

It will be appreciated that suitably increasing the height of the main drain hole, while solving the technical problem, also results in a corresponding increase in the height of the rim of the water storage box. That is, in order to ensure that the water pump can work normally when the dehumidifier is inclined in any direction, the height of the water inlet of the main drainage hole and the edge height of the water storage box are in a mutual contradiction relationship.
