Return airway ventilated type semiconductor refrigerating fruit and vegetable distributing box

Abstract

The invention discloses a return airway ventilated type semiconductor refrigerating fruit and vegetable distributing box. The return airway ventilated type semiconductor refrigerating fruit and vegetable distributing box comprises inside-and-outside embedded type double-layer box body, a control module, a refrigerating module, a ventilating module and a power supplying module; a return airway which extends from the front portion of the box body to the rear portion of the box body is formed in the interlayer of the inside-and-outside embedded type double-layer box body, the refrigerating module is used for achieving a refrigerating work mode and a heat insulation work mode, the ventilating module is used for achieving a front portion refrigerating and ventilating mode and a rear portion refrigerating and ventilating mode, the power supplying module is used for supplying power for the whole distributing box and suitable for power supplying of different input power types, and it is guaranteed that refrigerating is not interrupted in the conveying process. The defects that an existing distributing box is low in refrigerating efficiency, poor in cooling effect, large in volume mass of a refrigerating unit, unequal in temperature field distribution inside the box and the like are overcome.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping transportation of fruits and vegetables, in particular to a fruit and vegetable distribution box of a return air duct ventilation type semiconductor refrigeration fruit and vegetable distribution box. Background technique [0002] my country is a large vegetable country with high vegetable output, but due to the imperfect cold chain equipment, the loss rate in the process of fruit and vegetable logistics is as high as 25% to 30%, which is 4 to 6 times that of developed countries. Fruit is an important link in the cold chain logistics system. Due to the lack of targeted fruit and vegetable transportation equipment, the quality of fruits and vegetables during the transportation process has seriously declined, and the value of commodities has been affected. Existing fruit and vegetable distribution devices have problems such as extensive temperature control and uneven temperature field, which ...

AI Technical Summary

Problems solved by technology

During the transportation process, the temperature fluctuation range is large, and the temperature field distribution is uneven, which is unfavorable to the fresh-keeping transportation of fruits and vegetables
