Abstract

A purification dehumidifier includes a housing, a fan, a dehumidifier assembly, and a purifier assembly. The housing includes an air inlet, a dehumidified air outlet, and a purified air outlet. An air duct in communication with the air inlet, the dehumidified air outlet, and the purified air outlet is formed in the housing. The fan is arranged in the air duct and configured to introduce an airflow into the air duct from the air inlet and blow the airflow in the air duct out from at least one of the dehumidified air outlet or the purified air outlet. The dehumidifier assembly is arranged in the air duct and corresponding to the dehumidified air outlet. The purifier assembly is arranged in the air duct and corresponding to the purified air outlet.

First claim

What is claimed is:

1. A purification dehumidifier comprising:
a housing including an air inlet, a dehumidified air outlet, and a purified air outlet, an air duct being formed in the housing, the air inlet, the dehumidified air outlet, the purified air outlet being in communication with each other via the air duct, the air inlet, the dehumidified air outlet, and the purified air outlet being all arranged on a side wall of the housing, and the dehumidified air outlet and the purified air outlet being arranged separately;
a fan arranged in the air duct and configured to introduce an airflow into the air duct from the air inlet and blow the airflow in the air duct out from at least one of the dehumidified air outlet or the purified air outlet;
an air door assembly arranged in the housing and corresponding to at least one of the dehumidified air outlet or the purified air outlet, and configured to open or block the at least one of the dehumidified air outlet or the purified air outlet, wherein along an air outflow direction, the air door assembly is arranged between the fan and the at least one of the dehumidified air outlet or the purified air outlet;
a dehumidifier assembly arranged in the air duct and corresponding to the dehumidified air outlet; and
a purifier assembly arranged in the air duct and corresponding to the purified air outlet.

2. The purification dehumidifier of claim 1 wherein: the air door assembly includes an air door including a driving member, two swing blades, and a connection member connected with the driving member and the two swing blades; and the driving member is configured to drive the connection member to move to drive the two swing blades to rotate, so as to: form a gap between the two swing blades to open the at least one of the dehumidified air outlet or the purified air outlet; or allow the two swing blades to abut each other to block the at least one of the dehumidified air outlet or the purified air outlet.

3. The purification dehumidifier of claim 2 , wherein: the connection member includes: a first gear connected to the driving member; a gear rack engaged with the first gear; and two second gears each being engaged with the gear rack and connected to one end of one of the two swing blades; the driving member is configured to drive the first gear to rotate; the first gear is configured to drive the gear rack to move; the gear rack is configured to drive the two second gears to rotate; and each of the two second gears is configured to drive a corresponding one of the two swing blades to rotate.

4. The purification dehumidifier of claim 2 , wherein: one of the two swing blades includes a guiding inclined surface at a joint location to be sliced with another one of the two swing blades.

5. The purification dehumidifier of claim 3 , wherein the driving member includes a step motor.

6. The purification dehumidifier of claim 1 , wherein the fan includes a cross-flow fan.

7. The purification dehumidifier of claim 6 , wherein:
the cross-flow fan includes a volute and an impeller arranged in the volute;
an air inlet side of the volute is in communication with the air inlet;
an air outlet side of the volute in communication with the at least one of the dehumidified air outlet and the purified air outlet.

8. The purification dehumidifier of claim 7 , wherein:
the impeller extends along a height direction of the housing; and
a height of the impeller matches a height of the air inlet.

9. The purification dehumidifier of claim 1 , wherein the dehumidified air outlet and the purified air outlet are spaced apart from each other in a height direction of the housing.

10. The purification dehumidifier of claim 1 , wherein the air inlet, the dehumidified air outlet, and the purified air outlet are arranged along a circumferential direction of the housing.

11. The purification dehumidifier of claim 1 , wherein:
the dehumidifier assembly includes an evaporator and a condenser laminated along an air out-flowing direction of the dehumidified air outlet; and
the evaporator covers the dehumidified air outlet.

12. The purification dehumidifier of claim 11 , wherein the dehumidifier assembly further includes:
a water tank in the housing; and
a water receiving tray in the housing, the water receiving tray being below the evaporator and in communication with the water tank.

13. The purification dehumidifier of claim 11 , wherein the dehumidifier assembly further includes a compressor accommodated in the housing, the compressor being in communication with the evaporator and the condenser to form a refrigerant circulation loop.

14. The purification dehumidifier of claim 1 , wherein the purifier assembly includes a purification filter layer covering the purified air outlet.

15. The purification dehumidifier of claim 14 , wherein the purification filter layer includes an activated carbon filter layer and a high-efficiency air filter layer.

16. The purification dehumidifier of claim 1 , wherein: the air door assembly including a driving member, two swing blades, and a connection member including: a first gear connected to the driving member; a gear rack engaged with the first gear; and two second gears each engaged with the gear rack and connected to one end of one of the two swing blades.

17. The purification dehumidifier of claim 16 , wherein the two second gears are not engaged with each other.

18. The purification dehumidifier of claim 16 , wherein:
the gear rack includes:
inner teeth on a first side of the gear rack; and
outer teeth on a second side of the gear rack that is opposite to the first side;

the first gear is meshed with the outer teeth of the gear rack; and
the two second gears are meshed with the inner teeth of the gear rack.

19. The purification dehumidifier of claim 1 , wherein the dehumidified air outlet and the purified air outlet occupy side wall surfaces at different height positions of the side wall of the housing and are both opposite to the air inlet.

20. The purification dehumidifier of claim 1 , wherein the air door assembly includes:
an air door including two swing blades rotatable to:
form a gap between the two swing blades to open the at least one of the dehumidified air outlet or the purified air outlet; and
allow the two swing blades to abut each other to form an arc-shaped door body structure to block the at least one of the dehumidified air outlet or the purified air outlet.
