Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator, and more particularly to a cooling structure for a storage room for vegetables and the like.

[0002]

2. Description of the Related Art FIG. 4 and FIG.
It is a figure which shows the conventional refrigerator described in 13271 gazette. 4 is a vertical cross-sectional view taken along a plane orthogonal to the door, and FIG. 5 is a cross-sectional view taken along line GH of FIG.

In each figure, 1 is a refrigerator main body, 2 is a door for opening and closing the front opening of a storage chamber D, and 3 is a cooler A.
Coolers 4 provided inside the cooler room A and the freezer room B
A partition plate 5 for dividing and is provided in the freezer compartment B,
A decorative plate that forms an air passage C between the partition plate 4, a blower 6 for circulating cold air in the compartment, and 7 a freezer compartment B and a storage compartment D
And a divider 8 for dividing cold air from the storage chamber D provided in the divider 7, a cool air suction port 8a, a cool air duct 9 for sending cool air to the storage chamber D, and a 9a.
Is a cold air outlet, 10 is a storage case for vegetables and the like, which is arranged in the storage chamber D with a gap, and 11 is a lid that covers the upper opening of the storage case 10.

Next, the operation will be described. The cool air that has passed through the cooler 3 is blown into the air passage C by the blower 6 and flows out to each storage chamber as indicated by arrows in the figure. The cool air from the air passage C passes through the cool air duct 9 and flows into the storage chamber D from the cool air outlet 9a. A part of the inflowing cold air directly flows into the cold air suction port 8a to cause a short cycle, and the remaining cold air passes from the back surface of the storage case 10 through the bottom surface to the front cold air suction port 8a.
From a, it returns to the cooler 3 through the return air passage 8. As described above, since the cool air is still being distributed from the cool air duct 9 and is not distributed, the storage case 10 is locally cooled. The lid 11 at the upper opening of the storage case 10 prevents cold air from flowing into the storage case 10.

Since the cold air duct 9 is completely cooled by the cold air passing through the cold air duct 9, when there is a lot of humidity in the storage room such as when the door 2 of the storage room D is frequently opened and closed, dew condensation forms on the cold air duct 9 and Hang down.

[0006]

Since the conventional refrigerator is constructed and operates as described above, the cold air blown out from the cold air outlet 9a locally cools the lower portion near the cold air outlet 9a. If the inside of the storage case 10 becomes humid, dew will be partially condensed and the stored vegetables and the like will be damaged. In addition, the cold air blown out from the cold air outlet 9 a is stored in the storage case 10.
In addition to flowing to the back surface, a short cycle occurs in which it directly returns to the cold air suction port 8a, which makes it difficult to cool the storage case 10. Further, the cooled cool air duct 9 has a problem that dew condensation occurs when the inside of the storage chamber D becomes humid and the dew condensation water drips into the storage.

The present invention has been made in order to solve the above-mentioned problems, and improves the distribution of the blown out cool air to evenly cool the periphery of the storage case and eliminates the short cycle. The purpose of this is to improve the cooling of the inside of the refrigerator and to prevent water dripping inside the refrigerator due to dew condensation of the cool air duct 9.

[0008]

In order to achieve the above-mentioned object, in the present invention, the refrigerator has the following (1), (2), (3)
Configure as follows.

(1) A storage room for vegetables and the like having a cool air outlet on the rear side and a cool air inlet on the front side of the cool air outlet on the upper surface, and a storage case arranged with a gap in the storage chamber. And a lid body that covers the upper opening of the storage case, wherein the lid body is integrally provided with a cold air blocking rib that blocks cold air that directly flows from the cold air outlet to the cold air suction port on the upper surface thereof. Refrigerator that is installed in the room.

(2) On the upper surface, there is a storage room for vegetables or the like having a cool air outlet in the rear and a cool air inlet in front of the cool air outlet, and a storage case arranged with a gap in the storage chamber. And a lid for covering the upper opening of the storage case, wherein the lid is integrally provided with a cool air guide at a portion of the lid facing the cold air outlet. refrigerator.

(3) The refrigerator according to (2), wherein the cold air guide has a recess at the bottom thereof.

[0012]

With the configuration (1), the cold air that is about to flow directly from the cold air outlet to the cold air inlet is blocked by the cold air blocking rib on the upper surface of the lid. With the configurations (2) and (3), the cool air blown out from the cool air outlet is distributed around the storage chamber by the cool air guide at the rear part of the lid. In the configuration of (3), the condensed water that drops from the cold air outlet is once stored in the concave portion of the cool air guide and then vaporized and disappears.

[0013]

The present invention will be described in detail below with reference to examples. 1 is a vertical sectional view of a "refrigerator" which is an embodiment, FIG. 2 is a sectional view taken along the line JK of FIG. 1, and FIG. 3 is a perspective view of a lid. Since 1 to 10 in the figure correspond to the same reference numerals as those in the conventional example described with reference to FIGS. 4 and 5, the description thereof is omitted here. 11-1 is a lid, and 12 is this lid 11-
A cold air cutoff rib, which is located between the cold air outlet 9a and the cold air inlet 8a on the upper surface of 1, and extends vertically, 13 is a lid 11
-1 is a cool air guide integrally formed at the rear portion of the cold air guide -1, and 14 is a recess provided at the bottom of the cool air guide 13. The cool air guide 13 and the recess 14 thereof are provided in the cool air outlet 9 a of the cool air duct 9.
Is arranged at a position opposite to.

The lid 11 is placed on the convex portion 1a facing the interior side wall of the storage chamber D in the depth direction, and can be slid forward and taken out. The storage case 10 is placed in a frame composed of left and right frames (not shown) and a rear frame attached to the back surface of the door 2. Therefore, when the door 2 of the storage room D is pulled out, only the storage case 10 is pulled out while the lid 11 remains in the storage, and the vegetables and the like in the storage case 10 can be taken out. When the door 2 is closed, the lid 11 covers the upper opening of the storage case 10.

Next, the operation of the main part of this embodiment will be described. The cool air blown out from the cool air outlet 9a of the cool air duct 9 is blocked by the cool air blocking rib 12 to directly cool the cold air inlet 8a.
Does not flow into. Most of the cold air that blows out is the lid 1.
The storage case 10 is distributed so as to surround the storage case 10 by the cool air guide 14 formed at the rear of the 1-1.
Is cooled uniformly throughout. The dew that has condensed on the cool air duct 9 falls into the recess 14 provided in the cool air guide 13 and is collected. Since the cool air directly impinges on the concave portion 14, the condensed water that has been accumulated evaporates and disappears and does not drip into the refrigerator. By providing the cool air guide 13, the storage case 10 can be efficiently cooled, and thus the space between the inner part of the storage case 10 and the refrigerator main body can be reduced.

[0016]

As described above, according to the present invention, since the cool air blocking rib is provided on the upper surface of the lid and the cool air guide having the concave portion at the rear portion is integrally formed, the cool air blowing port and the cool air suction port are formed. Short cycle can be prevented, the cooling efficiency of the storage case can be improved, and the cool air is distributed so as to surround the storage case, so that the storage case can be uniformly cooled as a whole. Further, the condensed water from the cool air duct is once stored in the recess of the cool air guide and then vaporized to prevent water from dripping into the refrigerator.

Since the cold air blocking rib and the cold air guide are formed integrally with the lid, the manufacturing cost is almost the same as the conventional one.
