Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of food freezing equipment, especially relates to a cold air circulation structure of ice cream cabinet. BACKGROUND

[0002] The ice cream cabinet is a freezing cabinet for storing, displaying and selling ice cream, and is widely used in ice cream stores, supermarkets and other places. The existing ice cream cabinet on the market generally comprises a cabinet body and a refrigeration system, the upper end of the cabinet body is provided with a refrigeration chamber, and the refrigeration system is arranged in the cabinet body.

[0003] The refrigeration system of the ice cream cabinet is generally divided into a wind cooling system and a direct cooling system. The wind cooling system must be periodically defrosted, and the evaporator needs to be heated during defrosting. At this time, the temperature in the refrigeration chamber will rise, which is easy to exceed the melting point of the ice cream, and repeated melting and freezing will affect the appearance and taste of the ice cream. The evaporator of the direct cooling system is attached to the inner wall of the refrigeration chamber, and the temperature inside the refrigeration chamber is reduced by the evaporation of the refrigerant to absorb heat. Although there is no defrosting problem, the circulation of cold air in the refrigeration chamber is a natural convection circulation relying on the different air densities at different temperatures. The temperature at the lower layer of the refrigeration chamber is lower, and the temperature at the upper layer is higher. The temperature difference between the upper and lower layers is large. In order to facilitate the display and sale of ice cream, the user generally places the ice cream barrel in the upper middle part of the refrigeration chamber, i.e. in the area with a higher temperature, which is easy to cause the ice cream to melt, and will also affect the appearance and taste of the ice cream, resulting in poor user experience.
