Abstract

A dehumidifier assembly may include a housing having a top wall, a bottom wall, and one or more side walls. The top wall, bottom wall, and one or more side walls may define an internal cavity. A compressor may be disposed within the internal cavity adjacent to the bottom wall of the housing. A motor may be disposed within the internal cavity adjacent to the top wall of the housing, wherein the motor is a tip-magnetic driven motor. A heat exchanger may be disposed within the internal cavity and adjacent to at least one of the one or more side walls.

Claims (41)

1 . A dehumidifier assembly comprising:

a housing having a top wall, a bottom wall, and one or more side walls, the top wall, the bottom wall, and the one or more side walls defining an internal cavity;

a compressor disposed within the internal cavity adjacent to the bottom wall of the housing;

a motor disposed within the internal cavity adjacent to the top wall of the housing, wherein the motor is a tip-magnetic driven motor; and

a heat exchanger disposed within the internal cavity and adjacent to at least one of the one or more side walls.

2 . The dehumidifier assembly of claim 1 , wherein:

the compressor further comprises a top face, a bottom face, the bottom face having a center point;

the bottom wall further comprises a center point; and

the center point of the bottom face of the compressor is aligned with the center point of the bottom wall.

3 . The dehumidifier assembly of claim 1 , wherein the housing comprises a first side wall, a second side wall, a third side wall, and a fourth side wall and the housing forms a rectangular prism.

4 . The dehumidifier assembly of claim 3 , wherein the heat exchanger at least partially spans across the first side wall, the second side wall, the third side wall, and the fourth side wall.

5 . The dehumidifier assembly of claim 1 , wherein the motor further comprises one or more mounting holes.

6 . The dehumidifier assembly of claim 5 , wherein the motor further comprises a perimeter, and the one or more mounting holes are arranged around the perimeter.

7 . The dehumidifier assembly of claim 1 , wherein the motor further comprises:

a perimeter; and

one or more magnetic coils, wherein the one or more magnetic coils are arranged around the perimeter.

8 . The dehumidifier assembly of claim 1 , wherein the compressor is mounted vertically beneath the motor.

9 . A dehumidifier assembly comprising:

a housing having a top wall, a bottom wall, and one or more side walls, the top wall, the bottom wall, and the one or more side walls defining an internal cavity, wherein the bottom wall comprises a center point;

a compressor disposed within the internal cavity adjacent to the bottom wall of the housing, wherein:

the compressor comprises a top face and a bottom face, the bottom face having a center point; and

the center point of the bottom face of the compressor is aligned with the center point of the bottom wall of the housing;

a motor disposed within the internal cavity adjacent to the top wall of the housing; and

a heat exchanger disposed within the internal cavity and adjacent to at least one of the one or more side walls.

10 . The dehumidifier assembly of claim 9 , wherein the compressor is mounted vertically beneath the motor.

11 . The dehumidifier assembly of claim 9 , wherein the housing comprises a first side wall, a second side wall, a third side wall, and a fourth side wall and the housing forms a rectangular prism.

12 . The dehumidifier assembly of claim 11 , wherein the heat exchanger at least partially spans across the first side wall, the second side wall, the third side wall, and the fourth side wall.

13 . The dehumidifier assembly of claim 9 , wherein the motor further comprises one or more mounting holes.

14 . The dehumidifier assembly of claim 13 , wherein the motor further comprises a perimeter, and the one or more mounting holes are arranged around the perimeter.

15 . A dehumidifier assembly comprising:

a housing having a top wall, a bottom wall, a first side wall, a second side wall, a third side wall, and a fourth side wall, the top wall, the bottom wall, the first side wall, the second side wall, the third side wall, and the fourth side wall defining an internal cavity;

a compressor disposed within the internal cavity adjacent to the bottom wall of the housing;

a motor disposed within the internal cavity adjacent to the top wall of the housing; and

a heat exchanger disposed within the internal cavity and at least partially spanning across the first side wall, the second side wall, the third side wall, and the fourth side wall.

16 . The dehumidifier assembly of claim 15 , further comprising:

the compressor comprising a top face and a bottom face, wherein the bottom face has a center point; and

the bottom wall of the housing having a center point; the center point of the bottom face of the compressor is aligned with the center point of the bottom wall of the housing.

17 . The dehumidifier assembly of claim 15 , wherein the compressor is mounted vertically beneath the motor.

18 . The dehumidifier assembly of claim 15 , wherein the motor further comprises one or more mounting holes.

19 . The dehumidifier assembly of claim 18 , wherein the motor further comprises a perimeter, and the one or more mounting holes are arranged around the perimeter.

20 . The dehumidifier assembly of claim 15 , wherein the housing further comprises a rectangular prism.
