Abstract

A portable dehumidifier includes a plurality of microchannel condenser coils, a fan, and a retractable handle. The fan is located adjacent to an airflow outlet and is configured to generate an airflow that flows into the portable dehumidifier through an airflow inlet and out of the portable dehumidifier through the airflow outlet. The airflow flows through an evaporator and the plurality of microchannel condenser coils in order to provide dehumidification to the airflow. The retractable handle is configured to slide into and out of the portable dehumidifier and to pivot upwards and lock into a tilted position to allow for transport of the portable dehumidifier.

Claims

1. A portable dehumidifier, comprising:

two wheels;

an evaporator located adjacent to the airflow inlet;

a plurality of microchannel condenser coils;

a fan located adjacent to the airflow outlet, 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 plurality of microchannel condenser coils in order to provide dehumidification to the airflow; and

a retractable handle configured to;

slide into and out of the cabinet; and

pivot upwards and lock into a tilted position to allow for transport of the portable dehumidifier.

2. The portable dehumidifier of claim 1, wherein the retractable handle comprises:

a cross member; and

two sliding members coupled to the cross member, each sliding member comprising one or more pins.

3. The portable dehumidifier of claim 2, further comprising:

two bushing plates coupled to the cabinet; and

two brackets, each bracket coupled to a respective one of the bushing plates.

4. The portable dehumidifier of claim 3, wherein:

each sliding member comprises an inward-facing front pin and an outward-facing rear pin;

each inward-facing front pin is configured to engage with a notch on a respective one of the bushing plates in order to stop the retractable handle when it is being pushed into the cabinet; and

each outward-facing rear pin is configured to engage with a notch on a respective one of the brackets in order to stop the retractable handle when it is being extended out of the cabinet.

5. The portable dehumidifier of claim 3, wherein each bushing plate comprises a plurality of protrusions configured to guide a respective one of the sliding members into and out of the bushing plate.

6. The portable dehumidifier of claim 3, wherein:

each bushing plate is made of plastic; and

each bracket is made of metal.

7. The portable dehumidifier of claim 3, wherein:

each bushing plate comprises a transport stop that permits the retractable handle to pivot and stop in the tilted position;

each bushing plate comprises a transport lock configured to lock the retractable handle in the tilted position, each transport lock comprising a notch within its respective bushing plate; and

each sliding member comprises an end with a shape configured to be inserted into the transport lock.

8. A portable dehumidifier, comprising:

a cabinet comprising;

an airflow inlet;

an airflow outlet;

a plurality of microchannel condenser coils; and

a fan located adjacent to the airflow outlet, 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 an evaporator and the plurality of microchannel condenser coils in order to provide dehumidification to the airflow; and

a retractable handle configured to;

slide into and out of the cabinet; and

pivot upwards and lock into a tilted position to allow for transport of the portable dehumidifier.

9. The portable dehumidifier of claim 8, wherein the retractable handle comprises:

a cross member; and

two sliding members coupled to the cross member, each sliding member comprising one or more pins.

10. The portable dehumidifier of claim 9, further comprising:

two bushing plates coupled to the cabinet; and

two brackets, each bracket coupled to a respective one of the bushing plates.

11. The portable dehumidifier of claim 10, wherein:

each sliding member comprises an inward-facing front pin and an outward-facing rear pin;

each inward-facing front pin is configured to engage with a notch on a respective one of the bushing plates in order to stop the retractable handle when it is being pushed into the cabinet; and

each outward-facing rear pin is configured to engage with a notch on a respective one of the brackets in order to stop the retractable handle when it is being extended out of the cabinet.

12. The portable dehumidifier of claim 10, wherein each bushing plate comprises a plurality of protrusions configured to guide a respective one of the sliding members into and out of the bushing plate.
