Portable refrigerator with rechargeable battery pack
First Claim
1. A portable refrigerator, comprising:
- a main housing having an accommodating cavity for storing at least one item, and a power compartment;
a refrigerator cover provided on said main housing for selectively closing said accommodating cavity;
a cooling mechanism which is supported by said main housing and comprises a plurality of heat exchanging tubes, a compressor, an evaporator connected to said compressor through at least one of said heat exchanging tubes, and a condenser connected to said evaporator and said compressor through at least one of said heat exchanging tubes;
a rechargeable battery pack detachably attached on said power compartment of said main housing, said rechargeable battery pack being adapted for connecting to a power source; and
a central control unit supported in said main housing and electrically connected to said rechargeable battery pack and said cooling mechanism for centrally controlling an operation of said cooling mechanism, wherein a predetermined amount of refrigerant is arranged to controllably pass through said heat exchanging tubes, said condenser, said evaporator and said compressor for extracting heat from said accommodating cavity, wherein said central control unit comprises a charging control module, and a solar charging module electrically connected to said charging control module, said central control unit being configured to provide uninterruptible power supply so as to provide instantaneous protection from input power interruption to said cooling mechanism.

Abstract
A portable refrigerator includes a main housing, a refrigerator cover, a cooling mechanism, a rechargeable battery pack and a control unit. The cooling mechanism includes heat exchanging tubes, a compressor, an evaporator and a condenser connected to the evaporator and the compressor. The rechargeable battery pack is detachably attached on a power compartment of the main housing. The control unit is supported in the main housing and electrically connected to the rechargeable battery pack and the cooling mechanism for centrally controlling an operation of the cooling mechanism. A predetermined amount of refrigerant is arranged to controllably pass through the heat exchanging tubes, the condenser, the evaporator and the compressor for extracting heat from the accommodating cavity.
