Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a storage for freezing, refrigerating, warming, aging and the like of foods and the like.

[0002]

[Prior Art]

 In a conventional storage for the purpose of freezing, refrigerating, warming, aging, etc. of foods, as shown in FIG. 8 as an example of a refrigerator, the inside is surrounded by a heat insulating box 1 and the front surface is opened and closed by a door 2. A cooling unit 4 is installed on the upper part of 3, and the cooling air cooled through the cooling unit 4 is blown downward by the circulation fan 5 as shown by the arrow, so that the foods 7 placed on the net shelves 6 are removed. It is cooled, sucked into the cooling unit 4 again, and circulates in the interior 3. However, the cold air blown out by the circulation fan 5 is distributed and flows in the entire interior 3 due to its own inertia. However, since there are foods 7 and the like 7 directly exposed to the cold air and foods 7 and the like to which the cold air is hard to hit directly, there is a problem that the refrigerating action in the refrigerator 3 becomes uneven.

In the cold storage cabinet described in Japanese Utility Model Laid-Open No. 61-151185, a distribution plate is arranged in a ventilation passage along the side of a multi-stage shelf or tray in the cabinet. , The distribution plates have the same structure from the upper part to the lower part of the inside of the refrigerator, so most of the air flowing down the airflow passage flows intensively to the shelves or trays above the inside of the refrigerator by the first collision of the distribution plates. Or, if the distribution plate is small, due to the inertia of the air itself, it does not flow upward in the refrigerator, but most of it flows to the shelves or trays below the refrigerator, and it is actually distributed evenly throughout the refrigerator. Since it is impossible to do so, in reality, the same problems as the above-mentioned conventional device cannot be avoided.

[0004]

[Problems to be solved by the device]

 The present invention attempts to positively and surely allow cold air or warm air to flow to each shelf in the storage cabinet, and to adjust the effect of refrigeration or hot storage in the storage cabinet relatively evenly. It is a thing.

[0005]

[Means for Solving the Problems]

 For this reason, the storage according to the present invention comprises a shelf portion arranged in multiple stages inside the storage compartment, an air passage formed on the side of the shelf portion, an air blower for sending cold air or warm air to the air passage and the shelf. Is provided in the ventilation passage adjacent to the ventilation passage, and has a guide portion on the shelf portion for guiding the cold air or the warm air, and the guide portion gradually reduces the ventilation area from the upstream side to the downstream side of the ventilation passage. Is configured.

[0006]

[Action]

 Therefore, the cool air or hot air sent to the ventilation passage by the ventilation device is actively guided to the adjacent shelves by the guide portion provided in the ventilation passage, and the ventilation area of the ventilation passage is also increased by the guide portion. Can be gradually narrowed from the upstream side to the downstream side, and the flow rate of the ventilation passage can be gradually reduced.Therefore, the guide portion can reliably guide the cool air or the warm air from the ventilation passage to the upper and lower shelves. it can.

[0007]

【Example】

 Hereinafter, embodiments of the present invention will be specifically described. In FIG. 1, a refrigerator 10 constitutes an outer wall with a heat-insulating box 11, a front surface of which is opened and closed by a door 12, upper and lower multi-tiered net shelves 14 are installed in a refrigerating compartment 13, and ventilation of the rear ends of the net shelves 14 is provided. A vertical ventilation path 16 is formed between the duct 15 and the cooling air sucked from the inside of the refrigerating chamber 13 by the circulation fan 17 arranged at the bottom, and is cooled by the cooling unit 18, as shown by the arrow. After rising in the ventilation duct 15, it is blown out toward the ventilation passage 16.

Each of the guide plates 20 attached to the ventilation duct 15 so as to be positioned in the ventilation passage 16 adjacent to the rear edge of each net rack 14 has the net rack 14 as shown in detail in FIG. The lower guide plate 20 has a smaller ventilation area, and the lowermost guide plate 20 has no ventilation holes. The cold air passes through the ventilation holes 22 of each guide plate 20 in sequence and flows down in the ventilation passage 16, while being reliably and relatively evenly distributed and guided to the upper and lower net shelves 14 and placed on each net shelves 14. Even cold food is blown evenly to the foods, etc. 21 in which they are eaten, so that they can be cooled quickly and evenly.

Therefore, the whole foodstuff 21 etc. stored in the refrigerating compartment 13 is positively and effectively cooled, so that the reliability as a refrigerator can be enhanced. The lowermost guide plate 20 can be omitted by allowing the lower corner portion of the refrigerating chamber 13 to guide the cold air.

Further, FIG. 3 shows a modification of the guide plate. Each guide plate 30 has a shape bent toward the mesh shelf, and the lower guide plate 30 has a smaller ventilation area due to the plurality of rectangular ventilation holes 32. As in the case of the above-mentioned embodiment, the cold air is evenly blown to the foods and the like placed on the net racks. The ventilation holes 22 and 32 in the guide plates 20 and 30 can be easily replaced with comb-shaped cut grooves or the like in which the ventilation area becomes narrower toward the lower guide plate.

Further, FIG. 4 shows another modification of the guide plate, in which the guide plate 41 projects from the rear edge of each shelf 40 into the ventilation passage 16, and the distance between the tip of the guide plate 41 and the refrigerating compartment wall surface 42. As the lower plan plate 41 becomes smaller, and the lowermost guide plate 41 blocks ventilation, the ventilation area of the ventilation passage 16 decreases toward the downstream side. It is configured so that the food placed in it is uniformly blown with cold air.

FIG. 5 shows another embodiment of the present invention. In a refrigerator 50, a heat insulating box 51 constitutes an outer wall, a front surface is opened and closed by a door 52, and a refrigerator rack 53 is provided with upper and lower multi-shelf net shelves 54. In addition, vertical ventilation paths 56 are formed between the front edges of the net shelves 54 and the back surface of the door 52, and the ventilation area on the back surface of the door 52 becomes smaller toward the lower side like the guide plate. A guide plate 59 having a structure is attached to each of the mesh shelves 54. The guide plates 59 are provided in the ventilation passage 56 so as to be adjacent to the mesh shelves 54. The cooling unit 58 installed on the top of the refrigerator cools the circulation fan 57 to lower the ventilation. The cool air blown out toward the passage 56 passes through the guide plates 59 in sequence as shown by the arrow and flows down in the ventilation passage 56, and is reliably distributed to the upper and lower net shelves 54 by being guided by the guide plates 59. And food on each rack 54 Since 55 is similarly cooled and circulated to the cooling unit 58, the same effect as that of the above embodiment can be obtained.

6 and 7 show still another embodiment of the present invention, in which a refrigerator 60 constitutes an outer wall of a heat insulating box 61, a front surface of which is opened and closed by a door 62, and a refrigerating room 63 has a multi-tiered net rack. 64 are installed, and vertical ventilation passages 66 are formed between the left and right side edges of each net shelf 64 and the inner side surface of the heat insulating box body 61, respectively. A guide plate 69 having the same structure as that of the guide plate is attached, and the cool air cooled by the cooling unit 68 installed at the top of the refrigerator is arranged in the ventilation passage 66 so as to be adjacent to the mesh shelves 64. As described above, the air is shunted from the circulation fan 67 to the left and right, and is blown out toward the lower ventilation passages 66, and is sequentially guided through the respective guide plates 69 and guided by the respective guide plates 69 while flowing down in the left and right ventilation passages 66. Upper and lower nets Since it is surely distributed to the shelves 64 and the foodstuffs 65 on the net shelves 64 are similarly cooled and circulated to the cooling unit 68, the same effects as those of the respective embodiments can be obtained.

In each of the above-mentioned embodiments, the cold air is almost evenly applied to the food or the like in the refrigerating compartment, but when it is not necessary to apply the cool air to the food or the like placed on the lower shelf for some reason. The object can be easily achieved by closing the ventilation hole of the guide plate located immediately above it. Further, although each of the above-mentioned embodiments relates to the refrigerator, it is needless to say that the same structure can be applied to the freezer and that the blowing direction of the warm air to the ventilation passage by the air blower is upside down. It can also be applied to storages such as hot storage and aging storage.

[0015]

[Effect of the device]

 In the storage according to the present invention, the cold air or the warm air sent to the ventilation passage by the air blower is positively and surely guided to the adjacent shelves by the guide portion provided in the ventilation passage. The uneven performance can be easily eliminated, and the commercial property as a storage can be improved.
