DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage cabinet in which food trays, hotel breads, and the like are placed on a movable cart shelf with casters attached to a lower portion of a base, and more particularly, a cart shelf is provided. The present invention relates to a storage capable of storing cart shelves that can store foods efficiently and heat efficiently, while the cart shelves can be securely stored in the storages without the support of the cart shelves getting in and out of the storages.

[0002]

2. Description of the Related Art Conventionally, cart shelves having a plurality of shelves provided between columns supported on a base movable by casters have been used, and a food tray or the like is placed on each of the shelves of the cart shelves. Various types have been proposed in which the food is stored in a storage such as a refrigerator or a hot storage to store and cook the food.

For example, Japanese Utility Model Laid-Open Publication No. 59-136725 discloses a cart-like cart provided with a plurality of racks on which foods are placed on a cart-like cart with casters, and via a guide plate provided with guide rails. A steamer for other people, which is housed in a box-shaped outer case, is described.

In Japanese Utility Model Laid-Open Publication No. 59-114834, when a cart shelf is stored in a hollow body inside a heating chamber,
A cart shelf type oven provided with a space below the bottom plate of the heating cabinet in which a traveling cart of a cart shelf can be inserted and a notch provided at a front edge of the bottom plate to fit a lower end of a support of the cart shelf is described. I have.

[0005]

In the former steamer, the cart cart is housed as it is in the outer case together with the casters, and such casters are generally contaminated, so that they are very inconvenient for food. It is hygienic.

On the other hand, in the latter cart shelf type oven, when the cart shelves are accommodated in the heating cabinet, the traveling cart is not accommodated inside the heating cabinet, and the traveling cart is located below the bottom plate. Since it is arranged outside, the food can be kept hygienic unlike the former steamer. Also, when the cart shelf is accommodated in the heating cabinet, the lower part of the support column of the traveling cart is fitted into the notch formed at the front edge of the bottom plate in the heating cabinet, so that the support column does not interfere with the cart shelf. Can be appropriately arranged with respect to the heating cabinet.

[0007] However, the notch formed with the bottom plate in the latter cart shelf type oven is not provided with any member for covering the notch. Such a notch is always communicated with the outside of the heating cabinet, and therefore, while the cart shelf is not accommodated in the heating cabinet, there is a possibility that outside air outside the cabinet may flow into the inside of the heating cabinet through the notch. It is. Thus, when outside air flows into the heating chamber,
When the cart shelf is not accommodated in the heating cabinet, the heating cabinet cannot be efficiently heated in advance, and there is a problem that the food cannot be efficiently heated.

Further, in the cart shelf type oven, there is no means for guiding the traveling cart of the cart shelf below the bottom plate of the heating cabinet, and further, the cart shelf and the hollow body or the heating cabinet are connected. Nothing is provided for positioning. Thus, when guiding the traveling cart below the bottom plate and housing the cart shelf inside the heating cabinet, it is difficult to smoothly fit the lower part of the support of the cart shelf with the cutout of the bottom plate of the heating cabinet. Further, even after the lower portion of the column and the notch are fitted, the fitting of the two may be disengaged.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art. When a cart shelf is taken in and out of a storage, the cart shelf is smoothly placed in the storage without the support of the cart shelf being in the way. The present invention provides a storage capable of storing cart shelves that can guide and store the cart shelves while reliably positioning the cart shelves with respect to the storages and that can store foods with high efficiency by maintaining the inside of the storages at a predetermined temperature in advance. Aim.

[0010]

According to the present invention, there is provided a storage body having a front opening, a door for opening and closing the front opening, and a storage body provided on a back surface of a bottom plate of the storage body. A cart shelf having a leg member for separating a predetermined distance from the surface, and a shelf on which a plurality of food trays are placed between columns supported on a movable base,
In a storage that can be stored inside the storage from the front opening while moving the base below the bottom plate of the storage through the fixed interval, when the cart shelf is stored in the storage main body, the cart is opposed to the column. A notch formed at the front edge of the bottom plate, which covers the notch, and is movable in the storing direction of the cart shelf with respect to the storage main body and the extracting direction thereof, and is always elastically elastic in the extracting direction via an elastic member. The cart shelf is stored in the storage body while the covering member is moved in the storage direction via the support column, and the coating member takes out the cart shelf from the storage body. In the take-out direction.

The present invention also provides a magnet member disposed on a back surface of a bottom plate of the storage main body, and a metal member disposed on a part of the base opposed to the magnet member and adsorbed by the magnet member. And the magnet member is configured to adsorb the metal member in a state where the cart shelf is stored in the storage main body.

Further, the present invention is configured such that a guide member is provided on the back surface of the bottom plate of the storage main body and guides the base of the cart shelf below the bottom plate.

[0013]

According to the present invention having the above-described structure, first, the storage main body is preheated or cooled in order to maintain the internal temperature of the storage main body at a predetermined temperature. At this time, since the notch formed in the bottom plate of the storage main body is covered with the covering member, the inside of the storage can be efficiently maintained at a constant temperature without contact between the inside of the storage and the outside air. Then, after the food tray on which the food is placed is placed on a plurality of shelves provided on the cart shelf, the cart shelf is stored inside the storage main body from the front opening of the storage main body. At this time, the base of the cart shelf is smoothly guided into the inside of the storage main body via a guide member provided on the back surface of the bottom plate of the storage main body.

Further, when the cart shelf is moved into the storage main body, the support of the cart shelf moves the covering member in the storage direction against the elastic force of the elastic member. During such movement,
The covering member is moved while being in contact with a heat insulating material attached to mutually facing surfaces of the notch formed in the bottom plate.

[0015] Thereafter, the column is fitted into the notch. Thereby, the cart shelf is stored at an appropriate position in the storage main body. In this storage position, the magnet member disposed on the back surface of the bottom plate attracts the metal member disposed on the base of the cart shelf, whereby the cart shelf and the storage main body are positioned relative to each other. If the door is closed and the front opening is closed in this state, the food placed on each food tray is stored at a constant temperature in the storage main body.

Next, when removing the cart shelf from the storage main body, the door is opened and then the cart shelf is removed from the storage main body along the guide member while releasing the suction between the magnet member and the metal member. At this time, the support of the cart shelf comes off from the cutout of the bottom plate, and the covering member is moved in the removal direction while being in contact with the heat insulating material by the elastic force of the elastic member as the support moves. When the cart shelf has been removed from the storage main body, the covering member is returned to the original position by the elastic force of the elastic member.
