Abstract

A dehumidifier includes a machine body including a case. The case includes an air inlet, an air outlet, and an air duct communicating the air inlet and the air outlet. The dehumidifier further includes an axial flow fan arranged in the air duct. An air outlet direction of the axial flow fan is configured to face the air outlet. The dehumidifier also includes a compressor arranged inside the case and side by side with the axial flow fan.

First claim

What is claimed is:

1. A dehumidifier comprising:
a machine body including a case, the case including an air inlet, an air outlet, and an air duct communicating the air inlet and the air outlet;
an axial flow fan arranged in the air duct, an air outlet direction in which an air flow leaves the axial flow fan being configured to face the air outlet and being parallel to a rotation axis of the axial flow fan;
a compressor arranged inside the case and side by side with the axial flow fan; and
an evaporator and a condenser that are stacked and arranged in the air duct, each of the evaporator and the condenser having an overall shape of a U shape and including:
a first part facing a first side of the axial flow fan;
a second part facing a second side of the axial flow fan that is opposite to the first side; and
a third part connecting the first part and the second part, and facing a third side of the axial flow fan that connects the first side and the second side.

2. The dehumidifier of claim 1 , wherein the air inlet is one of a plurality of air inlets provided corresponding to a plurality of surfaces of the evaporator and the condenser.

3. The dehumidifier of claim 1 , wherein the evaporator is disposed closer than the condenser to an inner side wall of the case, and the condenser is disposed closer than the evaporator to the axial flow fan.

4. The dehumidifier of claim 1 , wherein the air outlet is located at a top of the case.

5. The dehumidifier of claim 4 , wherein:
a bottom of the compressor is fixedly connected to a bottom of the case and arranged vertically; and
the axial flow fan includes:
a drive motor vertically arranged corresponding to the air outlet; and
an axial flow impeller arranged closer than the drive motor to the air outlet.

6. The dehumidifier of claim 5 , wherein a top of the compressor is configured to extend to a middle part or an upper part of the drive motor.

7. The dehumidifier of claim 1 , further comprising:
a water tank including a receiving cavity;
wherein:
the machine body has a dehumidification function;
the dehumidifier has a working state and an idle state; and
the receiving cavity of the water tank is configured to:
store water formed by dehumidification of the machine body in the working state; and
receive at least part of the machine body in the idle state.

8. The dehumidifier of claim 7 , wherein:
the receiving cavity includes a support boss on an inner side wall of the receiving cavity;
the machine body includes an avoidance slot on an outer side wall of the machine body and corresponding to the support boss;
the support boss is configured to be received in the avoidance slot in the idle state to at least partially receive the machine body in the receiving cavity; and
the avoidance slot is configured to be staggered with the support boss in the working state.

9. The dehumidifier of claim 8 , wherein the support boss is vertically provided along a height direction of the water tank, and the avoidance slot is vertically provided along a height direction of the outer side wall of the machine body.

10. The dehumidifier of claim 8 , wherein:
the water tank includes a slot on an outer side wall of the water tank and corresponding to the support boss; and
a side wall of the water tank is configured to protrude inwards towards inside of the water tank to form the slot outside the water tank and the support boss.

11. A dehumidifier comprising:
a machine body including a case, the case including an air inlet, an air outlet, and an air duct communicating the air inlet and the air outlet;
an axial flow fan arranged in the air duct, an air outlet direction of the axial flow fan being configured to face the air outlet;
a compressor arranged inside the case and side by side with the axial flow fan; and
a water tank including a receiving cavity, the receiving cavity including a support boss on an inner side wall of the receiving cavity;
wherein:
the machine body includes an avoidance slot on an outer side wall of the machine body and corresponding to the support boss;
the support boss is configured to be received in the avoidance slot when the dehumidifier is in an idle state, to at least partially receive the machine body in the receiving cavity; and
the avoidance slot is configured to be staggered with the support boss when the dehumidifier is in a working state.
