Detailed Description

The following describes in further detail specific embodiments of the present invention based on the drawings. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

Referring to fig. 1 to 4, the dual-temperature-zone food fresh-keeping cabinet provided by the present invention includes a heat-keeping casing 10, a compressor 20, an evaporator 30, an internal food rack 40, an external food rack 50, an internal air deflector 60, an external air deflector 70, a fan mounting bracket 81, a lateral fan 82, a top fan 83 and an inclined air deflector 84. The top surface of the outer food rack 50 is recessed with a plurality of receiving pockets 51.

The compressor 20 is disposed outside the bottom of the heat-insulating casing 10, and the evaporator 30 is disposed inside the heat-insulating casing 10 and above the compressor 20. The compressor 20 and the evaporator 30 are connected by a low pressure pipe. The compressor pressurizes a low-pressure refrigerant into a high-pressure refrigerant, the high-pressure refrigerant enters the condenser for cooling, trace water in the refrigerant is filtered, the refrigerant enters the evaporator after being adjusted by the expansion valve in a proper amount, and the refrigerant returns to the compressor after passing through the low-pressure pipeline. The mechanism of the compressor 20 and the evaporator 30 is well known in the art and will not be described herein.

The top of the thermal insulation shell 10 is provided with a strip-shaped top opening 11, and the internal food rack 40 is horizontally arranged below the top opening 11. An outer food rack 50 is disposed horizontally above the top opening 11.

Fan mount 81 is L-shaped and includes a first side plate located on the side of evaporator 30 facing interior food rack 40 and a second side plate located above the top surface of evaporator 30.

A plurality of first ventilation holes are formed in the first side plate and the second side plate.

The side blower 82 is mounted on a first side plate and the top blower 83 is mounted on a second side plate.

The internal air deflector 60 is horizontally disposed at the top opening 11, a first end of the inclined air deflector 84 is connected to the bottom of the lateral fan 82, and a second end of the inclined air deflector 84 is connected to an end of the internal air deflector 60 close to the lateral fan 82, so that the inclined air deflector 84 is obliquely connected between the lateral fan 82 and the internal air deflector 60. The end of the internal air deflector 60 remote from the lateral fan 82 is located in the middle of the top opening 11.
