Abstract

A frost-free refrigerator is characterized in that a frost-free layer is arranged outside a refrigerating chamber, a freezing chamber and a condensing tube, and when the refrigerator is used, food water vapor can automatically fall off under the action of gravity even if attached to the frost-free layer to form small ice particles, the food water vapor can not form large blocks and be attached to the inner surface of the refrigerator or the inner surface of the condensing tube, ice removal is not needed, and the refrigerator is more ideal in use.

Description

Frost-free refrigerator

Technical Field

The present invention relates to a household appliance for storing and freezing food, i.e. a frost-free refrigerator.

Background

So far, refrigerators for domestic use are basically made of a single material, such as food-grade ABS or PVC plastic, and in use, a freezing chamber and a refrigerating chamber adjacent to the freezing chamber are often frozen, and if the ice is removed more and more thickly at irregular time, the storage amount of food and the freezing effect are affected, and if the ice is removed, the refrigerator is troublesome and time-consuming. So that the use always has a feeling of beauty deficiency.

The invention content is as follows:

in order to overcome the defects, the invention improves the conventional refrigerator sold on the market, namely the appearance and the whole refrigerator can be made of the materials of the conventional refrigerator, the difference is that a non-frosting layer made of non-frosting materials with proper thickness such as polytetrafluoroethylene and the like is attached to the surfaces of a freezing chamber and a refrigerating chamber by spraying and other processes, a non-frosting layer made of non-frosting materials such as polytetrafluoroethylene and the like is also attached to the whole outer surface of a condensing tube of the refrigerating chamber by spraying, soaking or other processes, the non-frosting layer is also attached to the whole outer surface of the condensing tube by the non-frosting materials such as polytetrafluoroethylene and the like, in order to influence the freezing effect as small as possible, the thickness attached to the non-frosting materials on the outer surface of the condensing tube is better about 10-20 micrometers, therefore, when food is frozen, water vapor of the food is attached to small ice particles formed on the non-frosting layer, the small ice particles can automatically fall off to a certain degree under the action of gravity, and is discharged from the refrigerating chamber drain pipe. No matter how long the refrigerator is used, the refrigerator never freezes on the surface layer of the condenser pipe or the refrigerating chamber, does not need manual deicing treatment, and is convenient and ideal to use.

The drawings are described below

The attached drawing is a partial sectional partial structure schematic diagram of a freezing chamber of a refrigerator.

In the attached drawings, 1 is a refrigerator main shell, 2 is a frost-free layer, and 3 is a frost-free condensation pipe.

DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

The specific implementation process of the invention is described with reference to the attached drawings, and the invention mainly comprises a refrigerator main shell 1, a frost-free layer 2 and a frost-free condensation pipe 3. The refrigerator main shell 1 can be made into a double-door by adopting plastic such as traditional food grade ABS or PVC or other materials, a refrigerator with a single door and a single door is provided with a cold storage and freezing refrigerator, but the inner surface of the refrigerator main shell 1 adopts non-frosting materials such as polytetrafluoroethylene spraying, soaking or other processes to integrally attach an additional layer with a certain thickness as a non-frosting layer 2, the non-frosting materials such as polytetrafluoroethylene and the like are also utilized on the outer layer of the condensation pipe, and the non-frosting condensation pipe 3 is manufactured by spraying, soaking or other processes on the periphery of the condensation pipe and hermetically wrapping a layer of the non-frosting layer, so that the influence on the condensation effect is reduced as much as possible, the non-frosting layer on the periphery of the non-frosting condensation pipe 3 can be thinner, and is generally 10 to 20 micrometers. The inner surface of the refrigerating chamber is attached with a non-frost layer by the same process as the inner surface of the freezing chamber.

Because the outer surfaces of the freezing chamber, the refrigerating chamber and the condensing pipe are provided with the non-frosting layers, when steam of food is attached to the non-frosting layers to form small ice particles, the ice particles can automatically fall off under the action of gravity and cannot be formed into large blocks to be attached to the inner surface of the refrigerator or the inner surface of the condensing pipe, the trouble of manual deicing is saved, and the use is convenient and ideal.

Claims

1. The utility model provides an avoid frost refrigerator comprises the refrigerator main casing body, not frost layer and not frost condenser pipe, its characterized in that: the non-frosting layer is attached to the inner surface of the main shell of the refrigerator and the outer surface of the condensation pipe, and the material of the non-frosting layer is made of polytetrafluoroethylene or other non-frosting materials.
