Problems solved by technology

In order to achieve thawing, the patent No. 201610374118.X discloses a refrigerator thawing method, but this thawing device uses soaking or washing to thaw the object, and the water tank and water circulation need to be additionally equipped with water pumps, which increases power consumption and costs Higher; Patent No. 201620693770.3 discloses a thawing device and a refrigerator with the thawing device, but this thawing device is heated by a heating device, which increases energy consumption, and the heating device is only installed at the bottom, which cannot thaw evenly
From this point of view, there are many problems in the existing thawing process and means: 1. The natural thawing rate of frozen food is too slow, and the bacterial growth is serious when exposed to the air for a long time. It is still frozen; 2. The heat preservation equipment consumes a lot of power to keep food warm for a long time, which increases additional energy consumption
[0003] In addition, the traditional refrigerator condenser is arranged in the foam layer, which mainly relies on directing heat to the outer wall of the refrigerator for natural convection heat dissipation, which has the problem of poor heat dissipation performance; the compressor mainly relies on natural convection heat dissipation in a small space. The high temperature device is arranged on the side wall of the refrigerator and freezer chamber, and the heat leakage is large, resulting in an increase in the temperature in the chamber

Embodiment 1

[0043] Such as Figure 1-7 As shown, in this embodiment, a refrigerator with a defrosting function is provided, and a condenser 4 is provided in the refrigeration system of the refrigerator. The refrigerator includes a thawing chamber 1 for thawing or keeping warm the stored objects, wherein the thawing chamber adopts the condenser as a heat source of the thawing chamber to thaw or keep the stored objects. There is heat loss in the heat exchange process between the condenser and the thawing chamber; there is a certain amount of heat leakage in the thawing chamber; even if the ideal state of no heat loss and no heat leakage is achieved, the temperature of the thawing chamber will not exceed the heat source (condenser) Therefore, there is no need to worry about the problem that the thawing room is too high due to the continuous heat release of the condenser; the whole heat exchange process of the thawing chamber is accompanied by the process of absorbing the heat of the condense...

Embodiment 2

[0057] In this embodiment, a thawing storage method for a refrigerator is provided. The method utilizes the refrigerator with a thawing function in the above-mentioned embodiment 1 to thaw and / or keep warm the stored items. When the refrigeration system is working, the temperature of the condenser 4 is high, and the heat of the condenser is absorbed by the phase change heat storage material 5, which changes from solid to liquid to store the latent heat of phase change. When storing objects (frozen food, etc.), the phase-change thermal storage material 5 will change from liquid to solid to release heat. When the thawing (insulation) chamber 1 does not need thawing (insulation), when the heat stored in the phase change heat storage material 5 reaches saturation, the condenser 4 dissipates the heat to the environment through the thawing outer wall 7 .

[0058] For thawing based on the above-mentioned refrigerator, the low-temperature food is placed in the thawing chamber and is i...

Abstract

The invention provides a refrigerator with an unfreezing function and an unfreezing storage method. A condenser is arranged in a refrigerating system of a refrigerator, the refrigerator comprises an unfreezing chamber used for unfreezing or preserving heat of stored objects, and the unfreezing chamber adopts the condenser as a heat source of the unfreezing chamber to unfreeze or preserve the heatof the stored objects. The refrigerator realizes unfreezing and/or heat preservation of the stored objects by utilizing the condenser, and has the advantages of good heat dissipation effect, energy conservation and the like.

Description

technical field [0001] The invention relates to the field of refrigerators, in particular to a refrigerator with a thawing function and a thawing storage method. Background technique [0002] Refrigerators have become an indispensable household appliance in daily life nowadays. Both refrigeration and freezing can realize the storage of food. However, frozen food often cannot be directly processed or eaten, so it often needs to be thawed, and even needs to be preserved. within a certain temperature range. In order to achieve thawing, the patent No. 201610374118.X discloses a refrigerator thawing method, but this thawing device uses soaking or washing to thaw the object, and the water tank and water circulation need to be additionally equipped with water pumps, which increases power consumption and costs Higher; Patent No. 201620693770.3 discloses a thawing device and a refrigerator with the thawing device, but the thawing device is heated by a heating device, which increases...
