Description

Quick freezer of refrigerator {APPARATUS FOR QUICK FREEZING OF REFRIGERATOR}

The present invention relates to a quick freezing apparatus for a refrigerator, and more specifically, to a quick freezing apparatus for a refrigerator, which can separate a quick freezing flow path formed in a freezer compartment of a refrigerator and a quick freezer formed with a cooling apparatus to increase the freezing efficiency. It is about.

In general, the refrigerator is divided into a freezer compartment for storing ice-making containers and frozen foods at a set temperature, and a refrigerating compartment in which refrigeration objects are stored, and a refrigeration cycle device is installed therein, and is circulated in a refrigeration cycle of compression, condensation, expansion, and evaporation. In the circulation circuit, the evaporator absorbs the heat from the outside to keep the inside freezing and refrigeration. In the conventional refrigerator, a freezer compartment is generally installed at the top of the refrigerator compartment, but a large refrigerator has a large refrigerator compartment. Side-by-side type refrigerators are often used in which the freezer and the freezer are installed on the left and right to store more food.

As shown in FIG. 1, the conventional refrigeration cycle of the refrigerator includes a compressor 41 for compressing a refrigerant having a low temperature and low pressure gas state and outputting the refrigerant as a high temperature and high pressure gas state refrigerant, and a high temperature and high pressure from the compressor 41. A condenser 42 for cooling and condensing a gaseous refrigerant with external air to liquefy, a capillary tube 43 for depressurizing and outputting a high-pressure liquid refrigerant from the condenser 42, and a reduced pressure from the capillary tube 43 The refrigerant is introduced and evaporated to a low temperature in a low pressure state to absorb heat, thereby cooling the evaporator 44.

In particular, the intercooled refrigerator includes a fan for discharging cold air to discharge cold air around the evaporator 44 to the freezer compartment and the refrigerating compartment to cool the inside of the refrigerator, and to control the operation of the fan and the compressor to control the inside of the refrigerator. Adjust the temperature.

In the refrigerator having temperature control based on the temperature of each of the freezer compartment and the refrigerating compartment, each fan for discharging cold air to the freezer compartment and the refrigerating compartment is independently driven to discharge cold air around the evaporator 44 to the freezer compartment and the refrigerating compartment, Keep the temperature of the refrigerator at the proper temperature.

In addition, since the food is easy to dissipate its taste and nutrients during freezing, the food is freeze-dried rapidly to freeze and maintain the taste and nutrients of the initial food.

In addition, the temperature range in which most of the moisture contained in the food is frozen is usually between -1 to -5 degrees. In this section, the quality of the food depends, and the freezing time of the section must be frozen as quickly as possible. Quality can be effectively maintained.

However, since the refrigerator having a conventional structure does not separately supply a quick freezing chamber for quick freezing inside the freezer compartment and a cold air supply to the quick freezing chamber, there is a disadvantage in that the taste and nutritional content of the frozen food are inferior.

The object of the present invention devised in view of the above point is to shorten the cooling rate of food by using a quick freezing chamber in which a separate cold air is supplied to the freezer compartment of the refrigerator, thereby effectively preserving the original taste and nutritional content of the food. The present invention provides a quick freezing device for a refrigerator.
