Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is suitable for commercial use where a large number of a small number of types are refrigerated / frozen to be used. The present invention relates to a refrigerator / freezer in which the stored items can be moved up and down from a loading / unloading port to a position where they can be easily removed by hand.

(Prior art) For commercial / household refrigeration / freezers where the stored items can be easily put in and taken out with the conventional hand,
It is located on the side of the freezer, and when loading and unloading the items stored in the freezer, the door of the loading / unloading port was fully opened and then pulled out horizontally.

(Problems to be solved by the invention) The refrigerator is operated by appropriately operating the refrigerator to cool the inside air so that the inside of the refrigerator / freezer always has a set temperature. The cooled air starts to stay at the bottom of the refrigerator and then spreads inside the refrigerator to cool the articles stacked vertically.

However, in conventional refrigeration / freezers, the doors on the side of the refrigeration / freezer are opened to access the stored items, so when the door is opened, the temperature is lower than the outside air and the heavy air inside the refrigerator is below the opened door. Flows out of the room and is replaced with high temperature outside air. Therefore, in the conventional refrigeration / freezer, the internal temperature rises every time the door is opened / closed, the stored items cannot be cooled stably and well, and the refrigerator frequently operates, resulting in cost increase. There was a point.

In addition, in the conventional refrigeration / freezer, when taking out the items stacked vertically, the user is forced to take various forward leaning postures depending on the size of the inside of the refrigerator and the position where the items are taken out. There was a problem. Further, in Japanese Utility Model Laid-Open No. 56-128492, a mechanism is provided in which a U-shaped groove is provided on the inner wall of the cabinet, a wheel for sliding the U-shaped groove is provided on the elevator board, and the elevator board is lifted by an arm rod and a chain belt. It is disclosed. This makes the mechanism complicated and unstable, and it is difficult to move up and down stably. Further, the elevating mechanism reduces the storage space in the refrigerator. Furthermore, the actual exploitation 5
Japanese Laid-Open Patent Publication No. 1-152993 discloses a structure in which a pantograph mechanism is provided below a midsole plate to move up and down.
This structure has the drawbacks that a wide space for the pantograph mechanism is required below, the storage space for the storage is reduced, and the structure is complicated and expensive.

(Means for Solving the Problem) The present invention has been made to solve the above-mentioned conventional problems, and when opening / closing a refrigerating / freezing room to take in / out a stored item, cold air in the case is exposed to the outside. A refrigerating / freezer that does not flow out and that can make the user's work posture easier by raising it to the required height, and can respond without increasing the height of the refrigerator and the volume of the occupied space. provide.

The gist of the idea is to provide an inlet / outlet on the ceiling surface of the refrigerator / freezer to allow the refrigerator / freezer to be put in and taken out by hand, and to suspend the floor panel inside the refrigerator with wires, ropes, chains and other ropes at the four corners. A refrigeration / freezer is provided with a drive means for driving the rope body to move the floor panel up and down to a height near the entrance.

(Operation) The refrigerator / freezer of the present invention is provided with an inlet / outlet for refrigerated / frozen products on the ceiling surface. Therefore, since the opening that communicates with the outside air in the refrigerator is only this ceiling surface,
Since there is no refuge for cold air in the refrigerator, outside air with a high temperature cannot enter the refrigerator. Therefore, since the temperature inside the refrigerator is always kept at the set temperature, the stored items can be cooled stably and well. Further, since the cool air does not escape, it is not necessary to operate the refrigerator for a long time.

Further, the refrigerating / freezing room is provided with a floor panel which is hung from a rope body such as a wire, a rope and a chain and which can be raised and lowered, and a driving means for the rope body which raises and lowers the floor panel.

Since the floor panel is hung from the rope, it is not necessary to change the height of the cabinet from the conventional one, and the height of the cabinet can be about the same as the conventional one. Also, since it is a cord, it can be stretched without increasing the chamber volume of the freezing / refrigerating room. The rope driving means only needs motors and simple accessory parts such as winding drums and sprockets, and it is compact and requires little space for installation. It also has a high degree of freedom in installation position and can be installed sufficiently in the conventional interior space. It has become a thing.

Place many storage items on the floor panel and place the floor panel at the lowest position in the cabinet. The user takes out the stored items one after another from the entrance on the ceiling surface. Then, when the upper part of the stored item becomes low and it becomes difficult for the user to take it in a free posture, the driving means is operated to raise the rope and raise the floor panel to bring the upper part of the stored item close to the entrance / exit opening. . As a result, the user can always work comfortably in a free posture.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

The freezer (1) of the embodiment shown in the drawings employs a wire rope as the rope (5), which is connected to the four corners of the flat floor panel (4) with the wire hooks (7) and attached above. It is wound around the take-up drum (8) outside the freezer compartment (2) via the pulley (6). The take-up drum (8) is provided at each end of a rotary shaft (10) that is driven to rotate by a motor (9) installed above the inside of the refrigerator.

In the figure, (3) is the access port, and (11) is the access port of the freezer compartment (2).
The lid of (3), the cooling pipe (12), and the heat insulating material (13).

In this embodiment, by operating the motor (9), the winding drum (8) is rotated to wind or unwind the rope (5) to move the floor panel (4) up and down. The cords (5) are located at the four corners of the freezing compartment (2) to minimize the reduction of the freezing space. The floor panel may be a flat plate, a perforated plate, a frame material, or a wire mesh.

(Effects of the Invention) As described above, according to the present invention, since the entrance / exit opening is provided on the ceiling surface of the refrigerator / freezer, and the floor panel for raising / lowering is provided in the inside of the refrigerator, cold air in the inside of the refrigerator is prevented when the stored items are taken in and out. The inside of the refrigerator can always be kept at the set temperature without escaping, and the stored items can be cooled stably and well. In addition, since the operating time of the refrigerator can be shortened, the running cost can be reduced. Further, since the floor panel is vertically movable and connected to the driving means, there is an advantage that the user can always work comfortably in a natural posture by raising and lowering the stored items to a position where they can be easily taken out. Furthermore, since the floor panel is hung with ropes, the height of the storage and the occupied space can be kept the same as the conventional one, making it practical.
