Open-style refrigerator structure

Abstract

This invention relates to an open-style refrigerated display case structure. The open-style refrigerated display case includes at least a main body, a display area, and a ventilation duct. It is equipped with a refrigeration unit and a control module. The refrigeration unit has refrigeration piping and heating piping. The refrigeration piping enables the evaporator of the refrigeration unit to generate cold energy, thus providing a low temperature for the open-style refrigerated display case. The heating piping enables the evaporator of the refrigeration unit to generate heat, thereby removing frost from the evaporator fins. This design lowers the internal temperature of the display case to a low temperature of 0-4 degrees Celsius or 2-4 degrees Celsius, improving the performance of the open-style refrigerated display case. Furthermore, the evaporator can defrost quickly without requiring an external heat source, thus enabling the refrigeration unit to achieve energy savings during operation.

Claims

1. An open-type refrigerated display case structure, the open-type refrigerated display case having at least a cabinet body, and a display section and an air duct section disposed on the cabinet body; the open-type refrigerated display case is equipped with a refrigeration unit and a control module; the refrigeration unit has refrigeration pipes and heating pipes, the refrigeration pipes enabling the evaporator of the refrigeration unit to generate cold energy to enable the open-type refrigerated display case to have a low cooling temperature; the heating pipes enabling the evaporator of the refrigeration unit to generate heat to remove frost from the evaporator fins of the evaporator.

2. The open-type refrigerator structure as described in claim 1, wherein, The heating pipe route is connected between the compressor and the evaporator, and a high-pressure discharge solenoid valve and a check valve are installed.

3. The open-type refrigerator structure as described in claim 1, wherein, The open-type refrigerator has an air intake at the bottom of the cabinet body; the bottom of the air duct can accommodate the evaporator of the refrigeration unit.

4. The open-type refrigerator structure as described in claim 3, wherein, The evaporator has a fan section and an evaporation fin assembly; the air duct section has a first air duct and a second air duct that connect the air intake, the first air duct has a first air outlet above the cabinet body and a first side air outlet that is spaced apart on the inner partition; the second air duct has a second air outlet above the cabinet body, and the first air outlet and the second air outlet are arranged adjacent to each other.
