Description

Refrigerator

The present invention relates to a refrigerator, and more particularly, to a cold air supply structure of a vegetable box provided in a lower portion of a refrigerating compartment and storing vegetables and the like.

In general, the refrigerator is configured to supply the cold air generated from the evaporator of the refrigeration cycle to the storage compartment to maintain the freshness of various foods for a long time.

As shown in FIG. 1, the refrigerator is a storage compartment having an open front in a cabinet 10 constituting an outer body, and includes a freezer compartment (not shown) for storing frozen food and a refrigerator compartment (30) for storing refrigerated food. Is formed so that, the door 50 for opening and closing it is hinged to the front surface of the cabinet (10).

In the upper portion of the rear side of the refrigerating chamber 30, a separate cooling chamber 20 is formed to generate and supply cold air, and the air of the evaporator 21 and the refrigerating chamber 30 which generate cold air is introduced into the evaporator 21. And a circulation fan 22 for forcibly blowing the generated cold air into the refrigerating chamber 30. In addition, the cold air duct 40 having the cold air discharge ports 41 arranged up and down is installed at the center of the rear wall so as to appropriately distribute the cold air to the refrigerating chamber 30.

In the refrigerating chamber 30, the shelf 32 is installed in the horizontal direction so as to store and store food, respectively, the shelf 32 is provided in multiple stages because the internal space is larger than the freezer (not shown). And the upper part of this is provided with a so-called specialty chamber 31 for storing fish, etc., the lower is configured with a separate vegetable box 33 for storing vegetables and the like containing moisture. The vegetable box 33 has a storage space 33a formed therein and is provided in an open box shape at an upper portion thereof, and is spaced apart from the bottom of the refrigerating chamber 30 by a predetermined interval. Accordingly, since the cold air passes through the gap between the bottom of the refrigerating compartment 30 and the bottom of the vegetable box 33, the inside of the vegetable box 33 is kept cold, and the cold air does not directly touch the vegetables, thus keeping the moisture of food as it is. Keep it long.

When the circulating fan 22 is operated in the refrigerator configured as described above, air in the refrigerating chamber 30 flows into the evaporator 21, which passes through the evaporator 21 to become cold and continues with the cold air duct 40 and the cold air discharge port. It is forcedly blown into the refrigerating chamber 30 through 41. Accordingly, the food stored in the shelf 32 of the refrigerating chamber 30 is stored in a refrigerated state, and at the same time, cold air circulates through the rear and bottom of the vegetable box 33, so that fresh vegetables and the like stored in the storage space 33a are also fresh. State is maintained.

On the other hand, fruits, vegetables, and the like stored in the storage space (33a) of the vegetable box 33, when the temperature is 5 ℃ or more, the ethylene gas and its own moisture is released by the respiratory action to reduce the freshness. That is, except for some subtropical crops, the storage temperature of the vegetable box 33 and the storage space 33a is set to about 5 ° C., because the lower the temperature, the lower the physiological activity such as their respiration and the longer the storage period. It is.

However, since the air is not circulated in the actual storage space 33a, a temperature deviation of about 3 ° C is generated depending on the positions of both sides and the center. That is, the center of the rear of the storage space 33a adjacent to the rear of the vegetable box 33 into which cold air is first introduced is also generated when cold air is directly introduced through a gap with the shelf 32 and maintained at about 2 ° C. The front and both sides of the storage space 33a adjacent to the front surface of the vegetable box 33 in which the heat-exchanged cold air passes or are hardly supplied are about 8 ° C. This is because the cold air duct 40 is installed in the center of the rear side wall of the refrigerating chamber 30, because most of the cold air supplied to the vegetable box 33 passes over the lower center of the vegetable box 33. Therefore, the temperature difference is severely generated as a whole of the storage space (33a), the stored food located on the front or left and right is less fresh than the rear.

In order to solve this problem, if the temperature of the vegetable box 33 accommodating space 33a is set to be maintained at around 0 ° C., the center of the rear of the accommodating space 33a adjacent to where cold air is introduced is about -3 ° C. Another problem is that vegetables and fruits freeze due to local temperature drop, causing cold water.

The present invention is to solve this problem, an object of the present invention is to provide a vegetable box for storing vegetables and the like in the lower part of the refrigerating chamber in which the refrigerated food is stored, to prevent cold air from flowing directly into the vegetable box By installing the cold guide plate so that the cold air is evenly distributed between the cold room and the bottom of the refrigerating compartment, it is to provide a refrigerator that maintains a constant temperature as a whole without a temperature deviation according to the position of the vegetable box storage space.
