Description

Vegetable box cover for refrigerator

The present invention relates to a vegetable box cover installed in the upper part of the vegetable storage compartment of the refrigerator, and in particular, by forming a guider on the dew condensation of the bottom of the vegetable box cover to guide the cold air flow to the lower end of the vegetable box cover bottom The present invention relates to a vegetable box cover for a refrigerator, which can prevent vegetables from being lost due to negative condensation dropping.

As shown in FIGS. 1 and 2, a general refrigerator is divided into a freezer compartment 10 and a refrigerating compartment 20, and the freezer compartment 10 includes an evaporator 11 for heat exchange and cold air generated from the evaporator 11. And a shroud 13 and a cold air passage 14 for guiding and circulating cold air in a predetermined direction and then discharging the cold air into the refrigerating chamber 20. 20 is comprised of the cold air duct 21, the cold air flow path 22, etc. for distributing cold air supplied to the refrigerator compartment 20 in each part. In the drawings, reference numeral 15 denotes a barrier, 30 a door, and 31 a door basket.

In addition, at the lower end of the refrigerating chamber 20, as shown in Figs. 1 to 3, a vegetable storage chamber V for storing and storing vegetables is provided separately. The upper portion of the vegetable storage compartment (V) is covered with a vegetable box cover 41 is separated from the refrigerating chamber 20, the inside of the vegetable box 40 to be opened and closed sliding.

Typically, the temperature of the vegetable storage chamber (V) is maintained about 2 ° C higher than the temperature of the refrigerating chamber 20, the humidity is maintained to about 90%.

Referring to FIG. 3, the flow of cold air in the above-described conventional vegetable storage chamber V is as follows.

Cold air formed by heat exchange in the evaporator 11 of the freezer compartment 10 descends into the refrigerating chamber 20 along the cold air flow passage 22 and flows into the vegetable storage chamber V, wherein the cold air is in the vegetable box cover ( 41 is flowed along the bottom surface and then circulated back to the refrigerating chamber 20.

As the cold air flows into the vegetable storage chamber V as described above, high humidity cold air collides with a predetermined portion A of the vegetable box cover 41 to saturate and intensively cools the portion. Dew is gradually formed on the part, and if this state continues, water accumulates and drops to the lower end of the vegetable box 40 when the water's own weight exceeds the surface tension.

As the condensation dropping phenomenon occurs, the conventional vegetable storage chamber (V) structure has a problem that the part is easily lost while the water drops on the vegetables accommodated in the vegetable box 40.

The present invention was devised to solve the above problems, by forming a guider in the dew condensed portion of the bottom of the vegetable box cover to guide the cold flow to the lower end of the vegetable box dew condensation drop (結露 積 荷) It is an object of the present invention to provide a vegetable box cover for a refrigerator that can prevent the defeat of vegetables caused by the phenomenon.

The vegetable box cover for a refrigerator according to the present invention for achieving the above object is provided with a vegetable box cover at the bottom of the refrigerating chamber to provide a space for the cold air can flow into the vegetable storage provided with a vegetable box sliding into the space In the structure of the seal, the vegetable box cover is characterized in that the bottom portion of the vegetable box can be guided in a predetermined direction to guide the flow of cold air flowing through the cold air flow path of the refrigerating chamber to the lower end of the vegetable box. .

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 and 2, the refrigerator according to the present invention is provided with a vegetable box cover 41 at the lower end of the refrigerating chamber 20 to provide a space for the cold air can be introduced and the vegetable box sliding into this space Applied to the structure of the vegetable storage chamber (V) provided with (40).

Unexplained reference numerals in the drawings of the present invention are the same as the description and corresponding names in the conventional drawings, the basic structure is similar to the conventional description will be omitted.

As shown in FIGS. 4 and 5, the vegetable box cover 41 protrudes the guider 42 in a predetermined direction in a bottom portion thereof, thereby allowing the cold air flowing in through the cold air passage 22 of the refrigerating chamber 20. It is configured to guide the flow to the lower end of the vegetable box (40).

5 and 6 show each embodiment of the vegetable box cover 41 according to the present invention.

In the vegetable box cover 41 shown in FIG. 5, the guider 42 protrudes from the bottom thereof in a vertically downward direction, and the hidden liner guider 142 has its tip side from the bottom of the vegetable box cover 41. It is formed to protrude so as to have a predetermined inclination angle in the direction, the inclination angle is preferably formed to approximately the same as the inclination angle of the inner surface of the vegetable box 40. The guiders 42 and 142 are integrally injection molded when the vegetable box cover 41 is manufactured.

In addition, the vegetable box cover 41 shown in FIG. 6 is configured to be detachable from the bottom of the vegetable box cover 41, the guider 242, the guider 242 has a form of a plate bent at a predetermined angle At the leading end and the bent portion of the guider 242, the insertion end 243 and the protruding groove 244 are formed, respectively, and the locking step 43 and the guide protrusion 44 formed on the bottom surface of the vegetable box cover 41. It can be combined with. The coupling is first inserted by sliding the projection groove 244 into the guide protrusion 44, and then the insertion end 243 of the guider 242 is fixed to the locking jaw (43). The guider 242 preferably uses a material having a low K-factor.

When explaining the operation of the vegetable box cover 41 according to the present invention made of such a structure based on the drawings.

Cold air formed by heat exchange in the evaporator 11 of the freezer compartment 10 descends into the refrigerating chamber 20 along the cold air flow passage 22 and flows into the vegetable storage chamber V, wherein the cold air is in the vegetable box cover ( Guided by the guide 41 of 41) flows to the lower end of the vegetable box 40 and then circulated back to the refrigerator compartment (20).

When the cold air flows into the vegetable storage chamber V as described above, the cold air reflected from the entrance port is redirected to the lower end of the vegetable box 40 by the guider 42 so that a predetermined portion of the vegetable box cover 41 is formed. Condensation phenomenon due to cooling of the specific portion is suppressed by the high-humidity cold air is not directly hit (B and C), so that the water droplets do not fall on the vegetables accommodated in the vegetable box 40 can be stored for a long time.

In the vegetable box cover 41 shown in FIG. 6, since cold air flows on the bottom of the guider 242, the same function as described above is performed.

Effects of the present invention that can be expected by the configuration and action as described above are as follows.

The vegetable box cover 41 for a refrigerator according to the present invention forms a guider 42 at a portion of which dew is formed at the bottom of the refrigerator to induce a cold flow to the lower end of the vegetable box 40, and the bottom of the vegetable box cover 41. By preventing a part of the surface temperature is lowered, condensation dropping phenomenon from a specific portion of the vegetable box cover 41 is not generated, thereby preventing the loss of vegetables accordingly, particularly effective in high temperature and high humidity environment There is an advantage to this.
