Description

[Detailed description of the invention] This invention relates to a refrigerator that cools stored items placed on shelves using forced circulation cold air flow, and is designed so that stored items located in front of the air outlet and suction port do not obstruct the blowing out and intake of cold air. ,
Moreover, the purpose is to maintain a uniform temperature distribution inside the refrigerator.

Generally, this type of refrigerator has a cover on the front of the cooler and blower that has an air outlet and a suction port on the top and bottom, and a shelf on the front of this cover to place stored items. In a refrigerator, the stored items located in front of the outlet and suction port become obstacles to the cold air being blown out and the cold air being sucked in. This not only impedes the circulation of cold air, but also separates the stored items near the outlet and those stored far away. The drawback was that there was a large temperature difference between the product and the product.

This proposal has been made in view of the above-mentioned drawbacks, and the embodiment thereof will be explained below with reference to the drawings. 1 shows an inner box 2 made of resin, an outer box 3 made of metal, and a foamed material filled between the inner and outer boxes. A refrigerator whose main body is constituted by a heat insulating material 4, and a plurality of openings are defined on the front surface of the main body by vertical and horizontal partitions 5 and 6,
A heat insulating door body 7 is provided at the opening.

The inner box has a vertically elongated protrusion 2 that protrudes forward at the center of the back surface.
A, and if necessary, a heat insulating partition wall 8 equipped with a flow control device 7 such as a damper is installed between the protrusion and the vertical partition 5 as shown by the broken line in FIG. 9 of them
It has the versatility of being able to use the left side as a freezer compartment and the right side as a refrigerator compartment.

10 is a cooler 1 provided along the left back surface of the inner box.
1 and the blower 12, the air outlet 13 is provided with a wind direction plate 15 that slopes downward from the front and blows out cold air diagonally from the lateral direction, and has an air outlet 13 on the top that slopes downward from the front and blows cold air from the diagonal lateral direction. A suction port 14 with a wind direction plate 16 for sucking air is formed at the bottom.

As shown in FIG. 5, the rain and wind direction plates are detachably provided so that they can guide cold air from left and right or from the same direction.

Reference numerals 17 and 18 indicate shelves disposed in the interior of the refrigerator 9, and a raised portion 19 is formed on the rear side of the shelf 18 adjacent to the cover to prevent stored items from falling.

According to the above configuration, the air outlet 13 and the suction port 14 are sloped downward in the front and downward in the rear, respectively, and a raised part 19 is formed on the rear side of the shelf 18 located on the front surface of the cover 10. Therefore, it is possible to form a cold air passage with a gap that does not impede the circulation of cold air between the outlet and suction port and the stored items, and the cold air from the outlet 13 is directed to the left or right by the wind direction plate 15 with respect to this passage. It is blown out in one diagonal horizontal direction, circulates to surround the stored items, and is sucked into the suction port 14 by the wind direction plate 16 from either the left or right or one diagonal horizontal direction.

Therefore, it is possible to obtain good cold air circulation by preventing the stored items located in front of the cover 10 from interfering with the cold air circulation, and to reduce the temperature difference between the stored items near the outlet 13 and the stored items far away. .

As mentioned above, the present invention has an air outlet at the top that is sloped downward in the front and equipped with a wind direction plate that blows out cold air in a diagonal horizontal direction, and an inlet that is sloped downward in the rear and equipped with a wind direction plate that sucks in cold air from the diagonal horizontal direction. A cooler and a blower provided on one side of the inner box are covered with a cover formed at the bottom thereof, and a raised part is formed on one side of the shelf adjacent to the cover. A sufficient gap necessary for cold air circulation is formed between the outlet and suction port and the stored items so that the cool air blown out and the cool air sucked in are not obstructed by the stored items, and the stored items near the outlet. It is possible to circulate cold air in such a way that there is no large temperature difference between the stored items and the stored items far away, and it is possible to equalize the temperature inside the warehouse and prevent deterioration and quality deterioration of the stored items.
