A special refrigerator for air duct air supply type cold storage

Abstract

The invention discloses a special refrigerator for an air flue air-supply-type refrigeration house. The refrigerator disclosed by the invention comprises a box body, a box door, an air supply hole, an air return hole and a temperature display, wherein the box body and the box door are connected through a hinge, a seal ring is arranged at the junction of the box body and the box door, and a buckling device is arranged at the opening and closing position of the box body and the box door; the air supply hole is formed on the lower right side of the rear side wall of the box body, the air return hole is formed on the upper left side of the rear side of the box body, the root, intersected with the air return hole, of the air supply hole is coated with sealing rubber, four grooves are formed in channels of the air supply hole and the air return hole, four terminals are arranged in each groove, and each terminal is connected to a wire; the temperature display is mounted above the front face of the box body and is connected to a 24v power supply through the wire, and the output control end of the temperature display transmits a control signal to electromagnetic valves in the air supply hole, the air return hole and the air flue through the wires. The refrigerator disclosed by the invention has the advantages of two types of refrigerators: (1) a refrigerator device is arranged in the box body, and the cost is low; (2) the air flue of the refrigeration house is connected to reduce the temperature, and the speed is high; and (3) the air flue is convenient to connect and the controllability is high.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a special refrigerator mainly used in an air duct air supply type refrigerator. Background technique [0002] With the rapid development of the economy, the refrigeration industry has sprung up. As the key equipment in the cold chain logistics process, refrigerators play an important role in extending the freshness period of food and reducing energy consumption. [0003] At present, there are mainly two types of refrigerators commonly used: 1) There is a built-in refrigeration device in the box, and the disadvantage is that the box must be powered by an external power supply and the cost is high; 2) The box is only made of insulation materials. Composition, its disadvantage is that the box body cannot be placed directly in the cold storage to cool down. When food is transported, it is necessary to take out the fresh food from the cold storage and put it into the refrigerator, which will inevita...

[0003] At present, there are mainly two types of refrigerators commonly used: 1) There is a built-in refrigeration device in the box, and the disadvantage is that the box must be powered by an external power supply and the cost is high; 2) The box is only made of insulation materials. The disadvantage is that the box cannot be directly placed in the cold storage to cool down. When food is transported, it is necessary to take the fresh food out of the cold storage and put it into the refrigerator, which will inevitably cause loss of cooling capacity.
