Description

[0001]
[Industrial application fields]
The present invention relates to a small-sized low temperature storage for storing a relatively small amount of grains such as rice and wheat and vegetables.
[0002]
[Prior art]
Conventionally, in order to prevent deterioration of the taste of stored rice and the like in a hot and humid period, a low temperature storage that keeps the temperature or humidity in the storage moderately throughout the year has been used. In such a low temperature storage, for example, when storing rice in 30 kg bags, the rice bags are stacked in order from bottom to top in several rows, so that the rice bags contact the wall surface in the storage and the circulation of cold air is hindered. There was a problem. In addition, when the number of stored rice bags decreases, it may be possible to store vegetables, for example, using the empty space, but it is not preferable for convenience to place vegetables etc. on the rice bags as they are. .
[0003]
[Problems to be solved by the invention]
The problem to be solved by the present invention is to provide a low-temperature storage with a simple structure, good circulation of cool air in the warehouse, and a safe shelf.
[0004]
In order to solve such a problem, the present invention provides a plurality of vertically extending ribs on the inner wall of the storage chamber, forms a notch for attaching a shelf member to a predetermined height portion of the rib , A hook for supporting the shelf member is provided at a lower cut end, a locking hole for engaging with the hook is provided at both ends of the shelf member, and both ends of the shelf member are inserted into the notch portions to lock the shelf member. A hook is inserted into the hole and a shelf member is attached in the cabinet .
[0005]
[Action]
According to the present invention, by providing ribs extending in the vertical direction at a plurality of locations on the inner wall of the storage chamber, the clearance between the rice bag and the rice bag is secured without contacting the storage chamber wall, and the cold air is circulated in the storage chamber. Is done smoothly. In addition, a shelf member that divides the storage chamber up and down is attached to the notch formed at the predetermined height of the rib, so that when the number of rice bags decreases, another shelf can be stored together by attaching the shelf member. Will be able to. And a shelf member is latched by the hook with which the notch part of the rib was equipped, and can place a heavy article stably. Since the hook is formed at the lower cut end of the rib, there is no protrusion into the storage chamber, and the rice bag is not caught and broken. Furthermore, since a gap is formed in the shelf member portion, the cold air easily flows in the horizontal direction.

【Example】
An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a low-temperature storage according to an embodiment of the present invention, and FIG. 2 is a front view of a state where a front door is opened. The low-temperature storage 1 includes a rectangular parallelepiped storage chamber 2 having an open front surface, two doors 3 for opening and closing the opening, and a cooler 4 provided on the upper portion of the storage chamber 2. 5 is a handle and 6 is a control panel.
[0007]
The door 3 is rotatably attached with the left and right ends of the front opening of the storage chamber 2 as vertical axes, and can be opened and closed by a handle 5 attached to the front surface of the door 3. A packing 7 is attached to the entire periphery of the rear surface of the door 3 so as to fill a gap between the door 3 and the main body 2 and seal the inside of the cabinet.
[0008]
As shown in FIG. 2, a plurality of ribs 8 extending in the vertical direction are provided inside the storage chamber 2, and the ribs 8 reinforce the wall surface of the storage chamber 2. A clearance with the stored item is ensured, and the cool air from the cooler 4 easily flows downward along the wall surface. Among the ribs 8, the rib 8 a provided on the inner wall forms a notch 10 at a certain height position to support the shelf member 9. The notch 10 can be added as appropriate depending on the number of shelves. The rib 8 is preferably made of a relatively soft plastic so as not to damage the rice bag or the like.
[0009]
FIG. 3 is an explanatory view of a shelf support portion in the low-temperature storage according to one embodiment of the present invention, and FIG. 4 is an explanatory view showing a configuration of the shelf member 9 and attachment to the notch portion 10.
The rib 8a is hollow and has a cushioning property, and a hook 11 for supporting the shelf member 9 is attached in the hollow. As shown in FIG. 3, the hook 11 has a crank-shaped vertical cross section, and the upper half protrudes upward from the lower cut end of the notch 10 to the inner wall of the storage chamber 2 in the lower half. It is fixed. As shown in FIG. 4, the shelf member 9 has a pair of left and right longitudinal cross-section L-shaped frames 12 and a length dimension slightly shorter than the width inside the box that is passed between the frames 12 and fixed at both ends. The horizontal portion 12 a of the L-shaped frame 12 is formed with a plurality of round pipes 13, and a locking hole 14 for engaging with the hook 11 is provided at a position corresponding to the hook 11.
[0010]
Next, attachment of the shelf member 9 will be described. First, the frame 12 at both ends of the shelf member 9 is inserted into the notch 10 of the rib 8a, and then the shelf member 9 is lowered at a position where the locking hole 14 of the frame 12 engages with the hook 11. Thus, the upper half of the hook 11 is inserted into the locking hole 14 and the shelf member 9 is easily fixed in the storage chamber 2.
[0011]
FIG. 5 is an explanatory diagram showing an example of use of the low-temperature storage of one embodiment of the present invention.
The inside of the storage chamber 2 is divided into upper and lower parts by a shelf member 9, and bagged rice grains 15 every 30 kg are stacked and stored in several rows as shown in FIG. 5. On the shelf member 9, bagged rice grains may be similarly stored, but it is also possible to store items other than rice grains such as vegetables and beer. Since the rib 8 is provided on the inner peripheral wall of the storage chamber and the slat 16 is provided on the bottom surface, even if the rice bag is stored from end to end of the storage chamber, the rice bag does not adhere to the wall surface, thereby blocking the flow of cold air. Stored without. Moreover, the flow of cool air in the horizontal direction is improved by dividing the storage chamber by the shelf member 9. The shelf member 9 is composed of a plurality of round pipes 13 and can be loaded so that heavy items such as rice bags can be slid onto the shelf, and since there is little chance of being caught by the round pipes 13, there is no risk of breaking the rice bags.
[0012]
In general, in the case of rice grains, a method of storing under conditions of a temperature of 15 ° C. and a humidity of 71% is employed in order to prevent pest and mold damage and moisture evaporation. The door 3 is made of a heat insulator, and the air inside the storage chamber 2 is cooled by the cooler 4 to maintain an optimum temperature for preserving the stored items throughout the year. For example, when the outside air temperature is 16 ° C. or higher, such as in summer, the temperature is always kept at 15 ° C. or lower. Further, a humidity control means may be provided in order to always optimize the humidity in the cabinet.
[0013]
【The invention's effect】
Since the low temperature storage of this invention is comprised as mentioned above, a rice bag does not contact the inner wall face of a storage chamber by a rib, and the circulation of cold air is ensured. Moreover, since the shelf member was attached to the storage room, when the number of rice bags decreases, the storage room can be effectively used by storing together other storage items. And by attaching the shelf member to the notch formed in the rib, it becomes possible to provide the shelf member to the full width of the storage chamber, and there is no backlash, and even when a heavy object is placed, it is stable. Become.
[0014]
Further, since the hook is provided in the rib, the protruding portion of the hook is covered, and there is no fear that the rice bag or the like is caught and damaged. Furthermore, the flow of cold air improves not only in the vertical direction but also in the horizontal direction due to the ribs and shelf members on the peripheral wall of the storage chamber, and the deterioration of the taste of the stored items such as rice grains and vegetables can be prevented.
