Drainage structure for defrosting water of cabinet freezer

Abstract

The invention provides a drainage structure for defrosting water of a cabinet freezer, and belongs to the technical field of cabinet freezers. The problems that an existing drainage structure is low in water outlet speed and the refrigeration effect is reduced are solved. The cabinet freezer comprises an evaporator, a water pan arranged at the bottom of the evaporator and a heating pipe arranged at the bottom of the evaporator and located above the water pan, the drainage structure comprises a water outlet hole penetrating through the water pan and a drainage connector arranged under the water outlet hole, the heating pipe is partially close to the water outlet hole, and the edge of the water outlet hole extends downwards to form a first heat conduction part. The inner diameter of the water inlet end of the drainage connector is larger than the outer diameter of the first heat conduction part, the first heat conduction part is inserted into the water inlet end of the drainage connector, a first heat insulation space is formed between the outer side wall of the first heat conduction part and the inner side wall of the water inlet end of the drainage connector, and the water outlet end of the drainage connector is used for being connected with a drainage pipe. The drainage structure has the advantages that the drainage speed is high, and the refrigeration effect of the cabinet freezer cannot be reduced.

Description

technical field [0001] The invention belongs to the technical field of freezers, and relates to a drainage structure for defrosting water in a freezer. Background technique [0002] The evaporator is the main component of the freezer for refrigeration. The freezer is generally equipped with an air-cooling system, which cools the stored items through air circulation to achieve uniform temperature in the freezer and obtain a good cooling effect. However, the air-cooled system will simultaneously store the items The moisture is brought to the evaporator to condense into frost, which affects the cooling effect of the refrigeration equipment. [0003] For the above problems, people have made various improvements, and some have applied for patents. For example, Chinese patent literature discloses a finned evaporator [application number: 201220320476.X; authorized announcement number: CN202734360U ], which includes an evaporator coil, several fins sleeved on the evaporator coil, s...

AI Technical Summary

Problems solved by technology

However, if the metal strip is worn in the drain pipe, the flow cross-sectional area of ​​the drain pipe will be reduced, and the flow speed of the defrosting water will be reduced. There is a problem that the defrosting water cannot be discharged in time; at the same time, the metal strip extends along the drain pipe, and the first heating pipe The heat is conducted to the metal strips, and there is a problem that the metal strips will transfer the heat to the freezer chamber of the freezer, reducing the cooling effect of the freezer
