BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling storehouse having a door provided on each of an upper surface and a front surface thereof so as to be freely opened and closed.

[0002]

2. Description of the Related Art Conventionally, this type of cold storage has been arranged adjacent to cooking equipment such as fryer in a kitchen or the like, and is frozen or refrigerated such as frozen potatoes fried by a fryer or hamburger patties baked on an iron plate. The ingredients are stored. The storage room of this cooling storage is cooled by forcedly circulating cold air by a blower for cooling,
A net rack is provided in the warehouse. Then, when cooking, the top door is opened to take out foodstuffs such as frozen potatoes and putty of refrigerated hamburger put on the net rack of the storage room. When the food items placed on the net rack become insufficient, the front door is opened, and the food items stored under the net rack are moved to the upper side of the net rack and placed on the net rack.

[0003]

By the way, when the front door is opened, the cool air in the upper part of the storage chamber moves downward and is discharged to the outside due to the difference in specific gravity between the cool air inside the storage chamber and the warm air outside the storage chamber. On the other hand, warm air outside the refrigerator enters the upper part of the storage room.
Therefore, each time the front door is opened and closed, the inside of the storage chamber, especially the upper part, is warmed, and the temperature of the foodstuffs placed on the net rack rises, which adversely affects the foodstuffs.

The present invention has been made to solve the above-mentioned problems, and it is intended to prevent the stored contents taken out by opening and closing the top door from being affected by temperature even when the front door is opened and closed. The object is to provide a cold storage that can be

[0005]

The cooling storage of the present invention comprises:
An insulating box (1) having a storage chamber (14) therein, an upper opening (9) formed on the upper surface of the insulating box, and a front opening (10) formed on the front surface of the insulating box; A top door (12) that opens and closes the top opening, a front door (13) that opens and closes the front opening, and a shelf that allows up and down circulation of air and is provided in the storage chamber. (26) and are provided. Then, in order to achieve the above object, it is considered to prevent the air above the shelf from flowing below the shelf. When the circulation of the upper and lower air is blocked in this way, the forced circulation system cannot efficiently cool the air. Therefore, in the cooling storage of the present invention, the inside surface of the heat insulating box is covered with the plate material (2) having good heat conduction, and the cooling pipe (6) comes into contact with the outside surface of the plate material. Is provided.

A partition plate (31) for substantially blocking the air flow is provided in order to prevent the air flow above and below, and the horizontal portion (31a) of the partition plate stores the upper part of the storage chamber. Room (14a) and lower storage room (14
b) and a rising part (31b) rising from the front end of the horizontal part almost blocks the flow of air between the upper part of the front opening of the heat insulating box and the upper storage chamber. There are cases.

The partition plate is detachable, and
The mounting position may be changeable up and down.

Further, a shelf receiver (25) whose mounting position can be changed up and down is provided in the storage chamber, and a partition plate may be supported by the shelf receiver.

The phrase "the partition plate blocks the flow of air" means that the partition plate blocks the flow of air to the extent that the cold air in the upper storage chamber does not flow out of the refrigerator when the front door is opened. This means that a small drain hole is formed in the partition plate and a small gap is formed between the partition plate and the inner surface of the heat insulating box. Further, in the heat insulation box, the side where the opening is formed is the front side.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of a cooling storage according to the present invention will be described with reference to FIGS. FIG. 1 is a front view of a cooling storage according to the present invention. FIG. 2 is a sectional view of FIG.

The heat insulation box 1 of the freezer as a cooling storage is
An outer box 3 which is a plate outside the cabinet, an inner box 2 which is a plate inside the cabinet inserted at a predetermined interval into the outer box 3, and a heat insulating material 4 is foam-filled between the inner and outer boxes 2 and 3. Is configured. The inner box 2 covers the inner surface of the heat insulating box 1 and is made of a material having good heat conduction, for example, a metal plate material such as stainless steel. A cooling pipe 6 is attached to the outside of the inner box 2, that is, the surface on the side of the heat insulating material 4 by a heat-conductive aluminum tape or the like before the heat insulating material 4 is filled. Is piped in a zigzag manner while being in contact with the surface of the inner box 2, which is a so-called tube-on-sheet cooling system. On the other hand, the outer box 3 can be made of a suitable material that is unlikely to cause rust, for example, a metal plate material such as stainless steel as in the inner box 2.

Then, an upper surface opening 9 is formed on the upper surface of the heat insulating box 1.
However, a front opening 10 is formed in the front surface, and a pair of slide type upper doors 12 are provided in the upper opening 9, while
A swing-type front door 13 is openably and closably attached to the front opening 10. This top door 12 and front door 13
Is a heat insulating door, and is a storage chamber 14 formed inside the heat insulating box 1.
It prevents the cold air from flowing out of the refrigerator. Further, a spatula 15 for defrosting is detachably attached to the upper front surface of the heat insulating box 1.

Further, a concave portion 1 is provided on the rear side of the lower portion of the heat insulating box 1.
6 is formed, and this recess 16 serves as a machine chamber, and is provided with a compressor 17, a condenser, and the like. A refrigerating cycle is constituted by the compressor 17 and the condenser and the cooling pipe 6 described above. Then, when the refrigeration cycle operates, the temperature of the cooling pipe 6 becomes low, and the storage chamber 14 passes through the inner box 2.
Is cooled. The heat generated by the compressor 17 and the condenser of the recess 16 is exhausted through the exhaust duct 19.

A basket 21 is provided on the upper portion of the storage chamber 14 so as to be slidable back and forth. Further, a pair of front and rear shelf support members 23 are provided on both the left and right sides of the storage chamber 14, and the shelf support members 23 are formed with shelf receiving holes 24 vertically in multiple stages. And a predetermined shelf receiving hole 2
A shelf receiver 25, which is a metal fitting for supporting the shelf, is detachably attached to the table 4. The shelf receiver 25 supports four positions on the front, rear, left and right of the net shelf 26. By properly changing the mounting position of the shelf receiver 25 in the vertical direction, the net shelf 2
The vertical position of 6 can be changed. In the case of the lowermost rack 26, only the front side is supported by the rack receiver 25, and the rear side is placed on the step portion 27 which is the upper surface of the recess 16.

Further, a partition plate 31 is placed on the upper net shelf 26, and the partition plate 31 is placed in the storage chamber 14.
Is divided into an upper storage chamber 14a and a lower storage chamber 14b. The partition plate 31 has a substantially L-shaped cross section, and the net shelf 2
6, a substantially horizontal horizontal portion 31a, and a rising portion 31 rising from the front end of the horizontal portion 31a.
It consists of b and. The horizontal portion 31a substantially blocks the flow of air between the upper storage chamber 14a and the lower storage chamber 14b. On the other hand, the rising portion 31b has an upper end reaching an upper portion of the front wall of the heat insulating box 1, that is, a portion of the front wall above the front opening 10, and allows the air to flow between the upper storage chamber 14a and the front opening 10. Is almost cut off.

As described above, the storage chamber 14 is composed of the upper storage chamber 14a.
The lower storage chamber 14b and the lower storage chamber 14b are partitioned by a partition plate 31 to prevent air from flowing between the upper storage chamber 14a and the lower storage chamber 14b, but the storage chamber 14 is cooled via the inner box 2. Since it is cooled by the pipe 6, both the upper storage chamber 14a and the lower storage chamber 14b can be cooled to almost the same temperature. By the way, in the case of the forced circulation type, if the flow of air between the upper storage chamber 14a and the lower storage chamber 14b is cut off, one storage chamber 14a or 14b can be cooled, but the other storage chamber It cannot be cooled.

Further, even if the front door 13 is opened in order to take in and out the stored items in the lower storage chamber 14b, the partition plate 31
In particular, since the rising portion 31b is provided, the cool air in the upper storage chamber 14a is prevented from flowing out of the refrigerator. Therefore, it is possible to prevent the temperature of the upper storage chamber 14a from decreasing.

When the upper door 12 is opened, the specific gravity of the warm outside air is smaller than the specific gravity of the cold upper storage chamber 14a, so that the cool air in the upper storage chamber 14a is washed out. And the temperature of the upper storage chamber 14a is not adversely affected.

Since the partition plate 31 can be moved up and down by appropriately moving the mounting position of the shelf receiver 25 up and down, the upper storage chamber 14a and the lower storage chamber 14b.
The capacities of the upper storage chamber 14a and the lower storage chamber 14b can be changed according to the amount of stored items stored in.

The embodiments of the present invention have been described above in detail.
The present invention is not limited to the above embodiment,
Within the gist of the present invention described in the claims,
Various changes can be made. Modification examples of the present invention are exemplified below. (1) The partition plate can be supported by the shelf receiver via the shelf as in the embodiment, or can be directly supported by the shelf receiver without the shelf.

(2) In the embodiment, the shelf receiver is detachably provided, but it is also possible to provide the shelf receiver in a state in which the shelf receiver is vertically fixed in multiple stages. (3) In the embodiment, the inner case 2 and the outer case 3 are made of the same stainless steel plate, but the material of the inner case 2 and the material of the outer case 3 can be different. For example, the outer box 3 may be a coated steel plate.

[0022]

In the cooling storage provided with the top door and the front door, the storage items placed on the shelves of the storage chamber are taken out by opening and closing the top door, while the storage items stored under the shelves are stored. Items are taken out by opening and closing the front door. Then, when the front door is opened and closed, the cool air above the shelf is discharged to the outside of the refrigerator.
In order to prevent this discharge, it is considered to block the flow of air above and below the shelf. In this way, if the circulation of the upper and lower air is cut off, the forced circulation type cooling cannot be performed efficiently. By the way, in the present invention,
The inside surface of the heat-insulating box is covered with a plate material having good heat conduction, and since the cooling pipe is arranged in contact with the outside surface of the plate material, the cooling pipe has good heat conduction. The storage room is cooled through the plate material. Therefore, the storage chamber can be efficiently cooled even if the circulation of air between the upper side and the lower side of the shelf is blocked.

Further, the partition plate divides the storage chamber into an upper storage chamber and a lower storage chamber so as to almost completely block the flow of air above and below, and between the upper and upper storage chambers of the front opening of the heat insulation box. In some cases, the circulation of air is also blocked. In this case, since the partition plate blocks the flow of air between the upper storage compartment and the outside of the upper storage compartment, even if the front door is opened and closed, the cool air in the upper storage compartment flows out of the refrigerator. Is prevented.

Further, when the partition plate is detachable and the mounting position can be changed up and down, depending on the amount of stored items above the partition plate and the amount of stored items below. The position of the partition plate can be changed to change the storage capacity of the upper part and the lower part of the storage chamber.

Further, when the storage chamber is provided with a shelf receiver whose mounting position can be changed up and down, and the partition plate is supported by this shelf receiver, the partition plate is supported by using the shelf receiver that supports the shelf. Since the position can be changed, it is not necessary to separately provide a support member for the partition plate, and the manufacturing cost can be reduced.
