Description

TECHNICAL FIELD The present invention relates to a storage cabinet, and more particularly, to a storage cabinet having a double structure in which a storage box is housed in an inner box of a heat insulating box,
The present invention relates to an improvement of a storage that suppresses a temperature difference between the inside and the outside of a storage box, prevents frost adhesion, and retains humidity.

2. Description of the Related Art Vegetables, fruits, and other fresh foods such as meat and fish (hereinafter referred to as "ingredients") are generally stored in the refrigerator when they are stored frozen in the refrigerator for a long period of time or when the frozen foods are gradually thawed. It is necessary to keep the temperature change small and to control the evaporation of water from food. In order to meet this demand, a storage box for storing foodstuffs is formed in a heat insulating box forming a refrigerating chamber, and a cooler cools a cool air passage defined between the heat insulating box and the storage box. A storage has been proposed in which cold air is circulated to cool the inside of a storage box, and the storage is widely and preferably implemented.

FIG. 4 shows an example of a double-structured storage cabinet in which a storage box is housed inside a heat-insulating box, and this storage cabinet has an outer box 2 having a large rectangular opening 2a on the front side. When,
A heat-insulating box body 1 comprising an inner box 3 which is incorporated in the outer box 2 with a required gap and which is also largely open to the front side, and a urethane foam heat insulating material 4 which is filled between both boxes 2 and 3. Have A storage box 10 made of a heat conductive metal plate such as stainless steel is disposed inside the inner box 3 of the heat insulating box 1 while holding the inner wall and a predetermined space. The storage box 10 has a rectangular opening 10a that opens forward in correspondence with the rectangular opening 1a opened in the heat insulating box 1.

Further, a cooler 5 is provided between the inner side wall of the inner box 3 and the outer side wall of the storage box 10 so as to be connected to a refrigerating device (not shown). The cooler 5 includes a direct cooling type in which the refrigerant coming from the refrigerating device is circulated to the built-in evaporator, and a refrigerant in the brine tank that circulates the refrigerant from the refrigerating device to the evaporator in the brine tank. And an indirect cooling type in which the brine is circulated in a heat exchanger. Whatever the type, the cooler 5 in the illustrated example is surrounded by a cooling duct 6 which is open at the bottom, and the air in the space 9 is guided by the duct 6
After being sucked from below the duct by the blower fan 8 provided in the upper opening 7, the cooling device 5 is brought into contact with the cooler 5 for cooling,
It blows out from the opening 7 and circulates in the space 9.

That is, in the space 9, the cool air blown from the blower fan 8 circulates as shown by the arrow, and cools the storage box 10 made of a good heat conductor. As a result, the temperature of the wall surface forming the storage box 10 decreases, and the foodstuffs stored in the storage box 10 (not shown)
Is cooled.

The loading shelf 18 shown in FIG. 4 is provided on both side wall parts 10b, 10b in the box.
b, the shelves 14 that are erected on the rear wall portion 10c, and the hook holes
It is fixed by being placed on the hooking member 16 provided on 14a.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the above-described double-structured storage, the rectangular opening 10a of the inner storage box 10 is always substantially sealed by a door (not shown). For this reason storage box 10
The inside of is a nearly completely sealed structure, but the space 9 outside it
The temperature inside and outside the box becomes large due to the cooled internal air circulating inside the box. Therefore, there is a serious drawback that frost adheres to the inner wall surface of the storage box 10 to lower the humidity inside the box and accelerate the drying of the food.

Further, inside the storage box 10, the shelf pillars 14 that support the mounting shelves 18 are arranged as described above, and project inward by the thickness thereof. Therefore, there is a drawback that the effective mounting area of the mounting shelf 18 on which food materials and the like are mounted is narrowed and the storage amount of food materials is limited as a whole. Furthermore, since it is necessary to separately prepare the shelf posts 14 for supporting the mounting shelves 18 and attach and fix them to the side wall surface inside the box, it is pointed out that the manufacturing cost increases and the assembling work becomes complicated. It

SUMMARY OF THE INVENTION The present invention has been proposed in order to suitably solve this problem in view of the above-mentioned problems existing in a double-structured storage cabinet in which a storage box is housed in a heat-insulating box, and The temperature difference between inside and outside is suppressed as much as possible, frost is prevented from adhering to the wall surface inside the box, the food is effectively prevented from drying, and at the same time, the limited volume inside the storage box is effectively used and at low cost. It is an object to provide a store which can be manufactured.

Means for Solving the Problems In order to overcome the problems inherent in the shelf support structure related to the above-mentioned double structure and to suitably achieve the intended purpose, the present invention provides
A heat-insulating box having an opening, a storage box that is hollow inside the heat-insulating box and forms a communication space between the inner wall surface of the heat-insulating box, and the opening of the heat-insulating box. Section and the opening of the storage box can be opened / closed correspondingly, a cooler arranged in the communication space, and air cooled by the cooler arranged close to the cooler in the communication space. In a storage that is provided with a fan that circulates inside the storage box and indirectly cools the inside of the storage box by the cooling air, a required number of through holes are formed in a vertical relationship on the left and right side wall surfaces and the back wall surface of the storage box. A plurality of holes are provided so that only a part of the cooling air circulating inside the communication space is introduced into the storage box, and at least the left and right wall surfaces are provided with the through holes. Removably attach and hold the hanging means Te, and characterized by being configured to mount the shelf mounting to the hooking means.

Embodiments Next, a storage according to the present invention will be described below with reference to the accompanying drawings with reference to preferred embodiments. The same members as those already described with reference to FIG. 4 are designated by the same reference numerals. FIG. 1 is a partially cutaway perspective view showing a housing structure of a horizontal storage according to a preferred embodiment of the present invention,
A heat insulating door that opens and closes the opening 1a of the heat insulating box 1
Twelve are provided. 2 is a vertical sectional front view of the storage shown in FIG. 1, and FIG. 3 is a vertical side view of the storage.

As shown in the figure, an appropriate number of through holes 20 are formed in the left side wall portion 10b, the right side wall portion 10b, and the rear surface wall portion 10c of the storage box 10 so that a space is formed between the storage box 10 and the inner box 3. A part of the cold air that circulates in the formed communication space 9 is allowed to enter the inside of the storage box 10 through the through hole 20. As described above, the required number of through holes 20 are formed on the inner wall surface of the storage box 10 so that a part of the cold air is introduced into the box, so that the communication between the inside of the storage box 10 and the outside of the box is achieved. The temperature difference in the space 9 can be suppressed as much as possible. That is, since there is almost no temperature difference between the inside and outside,
Moisture contained in the internal air of the storage box 10 does not condense on the inner wall surface of the box and adhere as frost, so that the decrease of humidity in the box is effectively prevented. Therefore, the foodstuffs stored in the box are prevented from being dried, which greatly contributes to maintaining the freshness of the foodstuffs.

The number of the through holes 20 and the arrangement pattern thereof are arbitrary as long as a part of the cool air circulating in the communication space 9 can enter the inside of the storage box 10 and suppress the temperature difference inside and outside the box.
For example, the through holes 20 may be formed on the left and right side wall surfaces and the back wall surface of the storage box 10 so as to have a plurality of stages in the vertical relationship, or a required number of holes may be formed on either the left or right side wall surface or the back wall surface. You may just set it up. Further, it is appropriately selected depending on the size of the internal volume of the storage box 10, the type of foodstuffs stored, and the like.

The through hole 20 can also function as a hooking portion of the hook-shaped hooking member 16 for fixing the mounting shelf 18, which will be described below. That is, the interval of the through holes 20 is set so that the left and right side wall portions 10 are formed as shown in FIG.
b, 10b and the back wall portion 10c are vertically separated by a predetermined distance,
A total of 5 steps (10 steps in total) with 2 steps on each surface.
This storage box 10 has a plurality of through holes 20 that are appropriately drilled in multiple stages.
The hook-shaped hooking member 16 made of a latch of the required shape.
Are fitted to each other, and then the net-like mounting shelves 18 are mounted on the hook members 16. The mounting shelf 18 is publicly known as shown in the drawing, and a wire rod made of a metal round bar is bent into a rectangular shape to form a frame body 18a. It will be fixed.

Further, it is necessary that the through hole 20 is set to have an opening size such that a required amount of space is present between the through hole portion 20 and the member 16 even when the hook member 16 is hooked. To be done. The reason is that if the hooking member 16 is hooked on the through hole 20 so that the through hole 20 is almost closed, the flow of cold air from the communication space 9 to the storage box 10 is blocked. This is because that.

Operation of the embodiment According to the storage according to this embodiment, a part of the cold air circulating in the communication space 9 is provided on both left and right side wall portions 10b, 10b of the storage box 10.
And a relatively upper through hole 20 formed in the rear wall portion 10c
Through the storage box 10 and through the through hole 20 provided below.
Escape to the communication space 9 via. The storage box 10 itself is
Since it is composed of a heat conducting member such as stainless steel, the storage box 10 itself functions as a cooling unit, and thus the mounting shelf 18
The foodstuff 22 placed on the container is cooled on both sides by the cold air circulating in the box through the through hole 20 and the cold air through the storage box 10 itself. The amount of cold air flowing from the through holes 20 is extremely small, and is only to assist the cooling by the storage box 10 itself. That is, since a large amount of cold air does not come into contact with the foodstuff 22, excessive evaporation of water in the foodstuff 22 is effectively suppressed.

Moreover, as described above, since a part of the cool air enters the box through the through hole 20, the temperature difference between the inside and the outside of the box is suppressed as low as possible, and the adhesion of frost to the inner wall surface of the box is prevented. Therefore, the humidity in the box is kept suitable, and the foodstuffs in storage are effectively prevented from drying. In addition, in the embodiment, the description has been mainly about the constant temperature and humidity refrigerator using brine as a cooling medium, but a cooling type storage having a double structure can be suitably applied to other types. Is.

Effect of the Invention As described above, the present invention has a double-structure storage in which a storage box is housed in a heat-insulating box, and has a plurality of through holes formed in the wall surface of the storage box. As a result, part of the cold air that circulates in the passage outside the storage box enters the box through this passage, so the temperature difference inside and outside the box is kept low, and frost adheres to the wall surface inside the box. To be prevented. Therefore, the humidity inside the storage box is properly maintained,
This has the great advantage that the drying of foodstuffs during storage is effectively prevented.

Further, since the hooking means is detachably hooked and held in the through hole formed in the wall surface, and the mounting shelf is attached to the hooking means, a member such as a shelf pillar protruding into the storage box is unnecessary. Can be By eliminating such obstacles, it is possible to set the size of the loading shelf itself to a large value, and it is possible to increase the amount of food stored in the loading shelf, thus increasing the limited volume of the storage box. It can be used effectively. Furthermore, by eliminating the need for a shelf or the like, it is possible to reduce the number of parts and manufacture at a low cost. Furthermore, since there is no member such as a shelf pillar protruding into the storage box, and the mounting shelf can be easily removed, the inside of the storage box can be easily cleaned, so that the hooking means, etc. The problem that the inside of the box becomes unsanitary due to soiling is also solved.
