Abstract

The present disclosure provides a humidifying device, including: a container, configured to accommodate a liquid; a first moisture absorptive member, partially or completely dipped in the liquid in the container; a second moisture absorptive member with air permeability, in contact with or isolated from the first moisture absorptive member; and a driving member, configured to control movement of the second moisture absorptive member, so as to allow the second moisture absorptive member to be in contact with or isolated from the first moisture absorptive member. The humidifying device according to the present disclosure can be applied in household appliances such as air cleaners and air conditioners. The operation and shut down of the humidification function is controlled, so as to avoid formation of superfluous air resistance when the humidification function is shut down. The present disclosure further provides an air cleaner and a household appliance, including the humidifying device provided according to the present disclosure. The air cleaner and the household appliance are not only simple in structure, effective in cost, and convenient in installation, but are also quiet when in operation.

First claim

What is claimed is:

1. A humidifying device, comprising:
a container, configured to accommodate a liquid;
a first moisture absorptive member, at least partially dipped in the liquid in the container;
a second moisture absorptive member with air permeability, in contact with or isolated from the first moisture absorptive member; and
a driving member, configured to move the second moisture absorptive member both into contact with the first moisture absorptive member and into a position isolated from the first moisture absorptive member.

2. The humidifying device according to claim 1 , wherein, when the second moisture absorptive member is brought into contact with the first moisture absorptive member, the second moisture absorptive member has a maximum blocking area, and when the second moisture absorptive member is isolated from the first moisture absorptive member, the second moisture absorptive member has a minimal blocking area.

3. The humidifying device according to claim 2 , wherein, the driving member comprises a driving motor and a driving connecting rod connected that are to each other, and the driving connecting rod connects to and drives the movement of the second moisture absorptive member.

4. The humidifying device according to claim 3 , wherein, the first moisture absorptive member is perpendicular to a still water surface of the liquid, and the driving connecting rod drives rotation of the second moisture absorptive member around a fixed end of the driving connecting rod, so as to allow the contact surface when the second moisture absorptive member is brought into contact with the first moisture absorptive member, to be parallel to the still water surface.

5. The humidifying device according to claim 1 , wherein, the first moisture absorptive member and the second moisture absorptive member are presented as cuboids or cylinders.

6. The humidifying device according to claim 1 , wherein, the first moisture absorptive member and the second moisture absorptive member comprise moisture absorptive bodies with a hygroscopic property, and the moisture absorptive bodies are at least one selected from a group consisting of wicks and dampening papers.

7. The humidifying device according to claim 6 , wherein, the first moisture absorptive member and the second moisture absorptive member further comprise supports covering surfaces of the moisture absorptive bodies.

8. The humidifying device according to claim 1 , wherein, the container comprises:
a water injection tank;
a closed chamber, comprising through-holes on the top thereof, wherein the first moisture absorptive member is placed within the closed chamber and communicatively connected to the outside via the through-holes; and
a drainage hole, communicatively connected to the water injection tank and the closed chamber.

9. The humidifying device according to claim 8 , wherein, the liquid is water.

10. An air cleaner, comprising the humidifying device according to claim 1 .

11. The air cleaner according to claim 10 , comprising:
a housing, comprising an air-in panel and an air-out panel;
an air strainer, provided downstream from the air-in panel;
the humidifying device, provided downstream from the air-in panel;
a fan, provided downstream from the air-in panel; and
the air-out panel, provided downstream from the air strainer, the humidifying device and the fan.

12. A household appliance, comprising the humidifying device according to claim 1 .
