Description

Refrigerator

The present invention relates to a refrigerator, and more particularly, to a cold air supply structure of a vegetable box provided in the lower portion of the 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, since the storage at a lower temperature lowers their physiological activity such as their respiration, so that the shelf life can be extended, the temperature of the actual vegetable box 33 storage space 33a is about 5 ° C. It is set.

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 wall of the refrigerating chamber 30, so most of the cold air supplied to the vegetable box 33 passes through the 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, the object of the present invention is to provide a vegetable box for storing vegetables and the like in the lower part of the refrigerator compartment where the refrigerated food is stored, cold air flow path so that the cold air is distributed evenly under the vegetable box The improvement is to provide a refrigerator that maintains a constant temperature as a whole without a temperature deviation caused by the position in the vegetable box storage space.

The refrigerator according to the present invention, as shown in these, a freezer compartment for storing frozen food (not shown) and a refrigerator compartment for storing refrigerated food (300) is formed in the cabinet 100, the front of the cabinet 100 The door 500 that opens and closes the door is hinged.

The cooling chamber 200 is formed at the rear of the refrigerating chamber 300, and an evaporator 210 for generating cold air is provided, and a circulation fan 220 is installed as a means for forcibly blowing the generated cold air. In order to guide the supply of cold air, a cold air duct 400 having a plurality of cold air discharge ports 410 arranged up and down is installed at the center of the rear wall of the refrigerating chamber 300.

In the refrigerating chamber 300, the special selection chamber 310 and the shelf 320 are configured in a horizontal direction to accommodate various stored foods. In the refrigerating chamber 300 having a relatively large internal space, the shelf 320 is provided as a kankan to store a plurality of refrigerated foods, and a box-shaped vegetable box 330 is configured to prevent cold air from directly touching the food. have.

The upper open vegetable box 330 is kept in a predetermined humidity to keep a predetermined humidity and other foods to prevent drying of various vegetables or fruits, such as to keep their moisture for a long time to store fresh. The vegetable box 330 having such a function is provided in a box shape having a storage space 330a formed therein, and is spaced apart from the bottom of the refrigerating chamber 300 by a predetermined interval, for the purpose of cold air circulation.

On the other hand, since the machine room 700 is formed in the lower part of the cabinet 100, such as the compressor 710 is formed, the bottom of the rear wall of the refrigerating chamber 300 adjacent to the rear of the vegetable box 330 is provided to be inclined. As a characteristic element of the invention, the distribution duct 600 for evenly dispersing the cold air supplied from the cold air duct 400 to the vegetable box 330 is installed. This is to prevent the temperature deviation caused by the position of the storage space (330a) by supplying the cold air so that the vegetable box 330 is uniformly cooled over the entire surface, the detailed structure thereof is as follows.

As shown in FIG. 3, the dispersion duct 600 includes an inlet 610 through which cold air is introduced and an outlet 620 through which the cold air is introduced. The inlet 610 having a predetermined width includes the cold duct 400. It is in communication with. And the outlet portion 620 is widened by the left and right width of the vegetable box 330 so that the cold air introduced through the inlet portion 610 is discharged while being widely distributed through the outlet portion 620, to increase the dispersion effect Inside the duct 600, a plurality of distribution guides 630 are installed upright. The dispersion guide 630 is coupled to be spaced apart at a predetermined interval. In addition, this is closer to the inlet portion 610 and the gap is disposed toward the outlet portion 620 toward the side, so that the cold air is widely dispersed and discharged smoothly. Accordingly, the cold air discharged from the outlet 630 of the dispersion duct 600 flows over the entire bottom of the vegetable box 330 and the refrigerating chamber 300, and the vegetable box 330 accommodating space 330a is uniformly cooled. This is explained in detail in the description of the operational effects.

Next will be described the operation and effect of the refrigerator according to the present invention configured as described above. First, when the circulation fan 220 is rotated, the cold air generated in the evaporator 210 is supplied to the compartment through the cold air duct 400 and the cold air outlet 410 to be cooled to the compartment and heat exchanged while cooling the stored food. The heat-exchanged air is introduced into the evaporator 210 again, re-cooled and supplied to the refrigerating chamber 300, so that the food stored in the refrigerating chamber 300 maintains a fresh state for a long time.

Meanwhile, the stored foods such as vegetables stored in the storage space 330a of the vegetable box 330 are kept fresh because the cold air is prevented from coming into direct contact with the food, which is widely distributed through the outlet 610 of the dispersion duct 600. It maintains a uniform state without temperature deviation by cold air discharged. That is, as described above, since the inlet portion 610 of the dispersion duct 600 communicates with the cold air duct 400 and the outlet portion 620 is widened, the cold air introduced into the dispersion duct 600 is internal. It is widely distributed and discharged while being guided by the dispersion guide 630 installed in the. The vegetable box 330 is heat-exchanged with the cold supplied by the dispersion, the air inside the storage space 330a is also uniformly cooled to maintain the same temperature regardless of position.

Therefore, the storage space 330a of the vegetable box 330 does not generate a temperature deviation without distinguishing the position between both sides and the center portion, and the fruits and vegetables stored therein can maintain a fresh state for a long time.

As described in detail above, the refrigerator according to the present invention is provided with a vegetable box for storing vegetables and the like in the lower part of the refrigerating chamber in which the refrigerated food is stored, the dispersion duct is installed so that the cold air is distributed evenly under the vegetable box.

Accordingly, the vegetable box is heat-exchanged with the cold supplied by the dispersion duct, thereby maintaining a constant temperature as a whole without causing a temperature deviation according to a position in the storage space, thereby maintaining the freshness of the stored food for a long time.
