Abstract

A portable dehumidifier includes a cabinet, an evaporator, a condenser, a drain pan, multiple support legs, a compressor, and a fan. The cabinet includes an airflow inlet, an airflow outlet, and at least two wheels. The evaporator is located adjacent to the airflow inlet. The condenser is located adjacent to the evaporator and on a side of the evaporator opposite the airflow inlet. The drain pan is located at least partially below the evaporator and the condenser. The support legs extend from a bottom side of the drain pan towards the bottom side of the cabinet. The compressor is located below the drain pan. The fan is located adjacent to the condenser and on a side of the condenser opposite the evaporator.

First claim

What is claimed is:

1 . A portable dehumidifier, comprising:
a cabinet comprising:
an airflow inlet located on a front side of the cabinet;
an airflow outlet located on a side of the cabinet; and
at least two wheels coupled to a bottom side of the cabinet;
an evaporator located adjacent to the airflow inlet; a condenser located adjacent to the evaporator and on a side of the evaporator opposite the airflow inlet; a drain pan located at least partially below the evaporator and the condenser, the drain pain configured to support weight of the evaporator and the condenser; a plurality of support legs extending from a bottom side of the drain pan towards the bottom side of the cabinet; a compressor located below the drain pan; and a fan located adjacent to the condenser and on a side of the condenser opposite the evaporator, the fan configured to generate an airflow that flows into the cabinet through the airflow inlet and out of the cabinet through the airflow outlet, the airflow flowing through the evaporator and the condenser in order to provide dehumidification to the airflow.

2 . The portable dehumidifier of claim 1 , wherein the plurality of support legs each comprise one or more cutouts that permit the airflow to circulate within the cabinet.

3 . The portable dehumidifier of claim 1 , wherein:
the compressor is coupled to a metal plate; a first plurality of grommets are included between the compressor and the metal plate; the metal plate is coupled to the cabinet; and a second plurality of grommets are included between the metal plate and the cabinet.

4 . The portable dehumidifier of claim 1 , wherein the fan is a variable-speed direct current (DC) impeller.

5 . The portable dehumidifier of claim 1 , further comprising a plenum disposed between the fan and the condenser.

6 . The portable dehumidifier of claim 1 , further comprising a filter disposed between the airflow inlet and the evaporator.

7 . The portable dehumidifier of claim 6 , wherein the filter rests on a portion of the drain pan.

8 . A portable dehumidifier, comprising:
a cabinet comprising:
an airflow inlet; and
an airflow outlet;
an evaporator located adjacent to the airflow inlet; a condenser located adjacent to the evaporator and on a side of the evaporator opposite the airflow inlet; a drain pan configured to support weight of the evaporator and the condenser; a plurality of support legs extending from a bottom side of the drain pan towards the bottom side of the cabinet; a compressor; and a fan configured to generate an airflow that flows into the cabinet through the airflow inlet and out of the cabinet through the airflow outlet, the airflow flowing through the evaporator and the condenser in order to provide dehumidification to the airflow.

9 . The portable dehumidifier of claim 8 , wherein the plurality of support legs each comprise one or more cutouts that permit the airflow to circulate within the cabinet.

10 . The portable dehumidifier of claim 8 , wherein:
the compressor is coupled to a metal plate; a first plurality of grommets are included between the compressor and the metal plate; the metal plate is coupled to the cabinet; and a second plurality of grommets are included between the metal plate and the cabinet.

11 . The portable dehumidifier of claim 8 , wherein the fan is a variable-speed direct current (DC) impeller.

12 . The portable dehumidifier of claim 8 , further comprising a plenum disposed between the fan and the condenser.

13 . The portable dehumidifier of claim 8 , further comprising a filter disposed between the airflow inlet and the evaporator.

14 . The portable dehumidifier of claim 13 , wherein the filter rests on a portion of the drain pan.

15 . A dehumidifier, comprising:
a cabinet comprising an airflow inlet; an evaporator located adjacent to the airflow inlet; a condenser located adjacent to the evaporator and on a side of the evaporator opposite the airflow inlet; a drain pan configured to support weight of the evaporator and the condenser; a compressor; and a fan configured to generate an airflow that flows into the cabinet through the airflow inlet and out of the cabinet through at least one airflow outlet, the airflow flowing through the evaporator and the condenser in order to provide dehumidification to the airflow.

16 . The dehumidifier of claim 15 , wherein:
the compressor is coupled to a metal plate; a first plurality of grommets are included between the compressor and the metal plate; the metal plate is coupled to the cabinet; and a second plurality of grommets are included between the metal plate and the cabinet.

17 . The dehumidifier of claim 15 , wherein the fan is a variable-speed direct current (DC) impeller.

18 . The dehumidifier of claim 15 , further comprising a plenum disposed between the fan and the condenser.

19 . The dehumidifier of claim 15 , further comprising a filter disposed between the airflow inlet and the evaporator.

20 . The dehumidifier of claim 15 , wherein the filter rests on a portion of the drain pan.
