Abstract

PURPOSE: A direct/indirect cooling compound type kimchi refrigerator is provided to suppress formation of frost due to variation of temperature and to extend term of preservation of food. CONSTITUTION: An upper storage compartment(20) uses direct cooling method as usual. A lower storage compartment(50) uses indirect cooling method to improve heat insulating quality. A fin-tube type heat exchanger(120) with excellent cooling efficiency is used for indirect cooling of the lower storage compartment. A duct(130) with a plurality of exhaust nozzles(130a) is installed to evenly distribute chilled air supplied by a fan(110) in the compartment. A receiving part(50a) formed on one side of the lower storage compartment by a bracket(122) has the fin-tube type heat exchanger mounted therein to cool down air in the compartment by refrigerant supplied by a condenser in a machine room(70). The fan is mounted on a front side of the fin-tube type heat exchanger by a fixer(112). The fan is rotated by a motor(114) to forcibly transport air in the compartment to the fin-tube type heat exchanger. Air in the compartment forcibly transported by the fan to the fin-tube type heat exchanger is cooled down through heat exchange with refrigerant passing the fin-tube type heat exchanger, and moved to the duct.

Description

Direct-to-Air Combination Kimchi Refrigerator {DIRECT AND INDIRECT TYPE COMPOUND KIMCHI REFRIGERATOR}

The present invention relates to a direct-to-direct type combined kimchi refrigerator. More specifically, the upper reservoir is directly cooled by using an evaporator pipe wound around an inner container, and at the same time, the fin kimchi in the lower reservoir. It relates to a direct-to-air type combined kimchi refrigerator configured to indirectly cool vegetables, meat, etc. in a refrigerator by mounting an evaporator of a type.

In particular, in the case of Korea, which uses rice as a staple food, various pickles have been developed by adding various seasonings to vegetables such as cabbage and radish, and then ripening them appropriately. Among these pickles, kimchi is a fermented food that has been soaked for a long time, and a large amount of kimchi has been stored in cold winter and eaten little by little. It was difficult to store kimchi in hot summer when there was no refrigerator, but with the advent of electric refrigerators it was possible to store kimchi for longer periods in summer.

However, in the case of the refrigerator, the kimchi is gradually rancidized in the process of frequently opening and closing, so that the ripe taste cannot be maintained as it is, and the freshness is lowered. In order to solve this problem, kimchi refrigerators that are suitable for ripening kimchi according to seasons and tastes and then cooled at a low temperature to preserve the taste of kimchi for a long time are widely used.

In the early Kimchi refrigerator, the main method was to store the kimchi by opening the upper door, but the drawer method was introduced to store the kimchi by storing the drawer type kimchi storage container in the main body of the kimchi refrigerator by using the drawer method. There is also a growing trend to increase the spread of the combined kimchi refrigerator with a vertical storage and a drawer storage opened by the upper door.

1 and 2 are a perspective view and a cross-sectional view showing the internal and external configuration of a general composite kimchi refrigerator. Looking at the overall configuration thereof, it is formed integrally in the interior of the outer case 10 via the outer casing 10 and the heat insulating material 90 of the cabinet form forming the appearance of the Kimchi refrigerator and the upper reservoir 20 inside. Inner container (12) to provide a), the lower container 51 is disposed on the front of the kimchi refrigerator is installed retractable forward and provides a lower reservoir 50 therein, a compressor (60) and a condenser (not shown) And a machine room 70 in which a cooling device is installed).

As shown in FIG. 1, the door 30 used to open and close the upper reservoir 20 is rotatably mounted on the upper portion of the outer case 10 by the hinge 40. The upper part of the outer case 10 is attached to the control panel 80 for setting and controlling the overall operating state of the kimchi refrigerator, the front panel 53 constituting the lower container 51 for easy withdrawal The handle 52 is attached.

As shown in more detail in FIG. 2, the inside of the upper reservoir 20 is configured to load and store the kimchi container 21 in two stages in general, and to directly cool the inside of the upper reservoir 20. On the outer circumferential surface of the container 12, a heater 26 for heating the inside of the furnace is wound at predetermined intervals, including a pipe-shaped evaporator 24 through which a refrigerant passes.

On the other hand, in order to cool the lower reservoir 50 used for mainly storing vegetables such as cabbage and radish, fruits and meats, the lower evaporator 100 in the form of a pipe is also arranged in the upper part of the inside of the indirect cooling system. It is possible to maintain the inside of the refrigerator within the set temperature range.

In the conventional composite kimchi refrigerator having such a configuration, since the heat is transferred through the injection-molded product in the configuration of the lower reservoir, the cooling efficiency is lowered, thereby limiting the storage period of the food being stored. In particular, when the lower evaporator is manufactured, the heat insulating material (90) Since the injection molding together with the heat transfer efficiency is lowered, the temperature deviation in the height is increased, there is a problem that causes consumer complaints due to sexuality.

In order to solve the above problems, the present invention improves the heat transfer characteristics by adopting an indirect cooling method instead of the direct cooling method of the lower reservoir, thereby suppressing occurrence of frost caused by temperature deviation and extending the shelf life of food. The purpose of the present invention is to provide a direct chilled combined kimchi refrigerator.
