Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening and closing device for a cold-holding shutter for a food refrigerated showcase.

[0002]

2. Description of the Related Art Conventionally, as a shutter, a slat type or an insulated sheet type has been put into practical use as a shutter system in addition to a simple film night cover system.
However, in this case, as for the opening and closing device of the closed type shutter, a winding type in a dedicated storage box installed above the optional case opening is mainly employed. In addition to the problem of the appearance, there is a lot of waste in the structure of the apparatus, and the inconvenience of attaching and detaching a dedicated post to seal the gap between each shutter and the main body is involved.
In addition, the dew condensation of the shutter itself could not be easily dried, and the cost was further reduced.

[0003]

SUMMARY OF THE INVENTION In an opening / closing device for completely covering the entire opening of an open case using a heat insulating shutter having a heat insulating performance, a storage and draw-out mechanism is provided. -The initial design structure is integrated with the case body, and the cost is greatly reduced, which was the limit of the conventional closed-type open / close shutter of the post-installation type as an option. It is an object of the present invention to provide a design structure in which dew condensation generated during operation of the shutter is naturally dried during storage of the shutter to enhance hygiene management, and an open case for all food refrigeration is provided. The purpose is to facilitate the installation and spread of hermetically sealed insulated shutters, thereby significantly saving electricity costs, saving energy, and extending the food holding period. .

[0004]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides an up-down slide type in which a fixed-length front case is continuously or entirely covered with an opening. Using a resin-made slat type or a cooling shutter having flexibility such as various heat insulating sheets, a predetermined height is provided in the depth direction on both upper sides of each of the upper parts by using the upper top plate of each case body. Providing a side panel and an upper cover
The ceiling of the case main body is formed as a device storage case, and bearings are provided on both side panels so that a plurality of rollers that can be rotated forward and backward are arranged horizontally along the frontage and in the depth direction. Are arranged in parallel with each other, and the shutter which is drawn in from the front entrance of the storage case is provided with the arranged bend rollers and
It is pulled in to the full depth by a rotary roller or the like, or it is turned into a loop by a turn roller at the back, and it is taken up directly by a roll or by a shutter. -A structure in which a lead member such as a cloth or a rope is connected to the back end and wound up, so that the shielding shutter provided at the opening of the case is easily pulled in and pulled out. In addition, it is kept in a state of being always extended in the storage case to enable the air drying of dew condensation. At this time, a return spring structure in which a coil spring is built in the take-up roller allows the shutter to be easily opened and closed by a manual operation. The lead member can be extended to the lowermost end of the entire length of the shutter and attached as a tension member. In addition, since the storage case of the present apparatus is formed by covering the entire outer surface of the upper part, sufficient measures are taken in hygiene management. In addition, a part of the front entrance / exit device including the bend drawer of the storage / extraction device is usually provided with lighting equipment and instrument storage services provided at the upper part of the opening of each case. The service box is extended and installed on the upper part of the screw box, the upper cover part of this storage case part is divided in the width direction of a predetermined width, and a hinge mechanism is provided on the upper part to form a box-shaped opening / closing lid structure built in the device. Inspection is easily formed.

[0005] In addition, adjacent shutters which are pulled out from a fixed-size storage case, which is separated from each of the consecutively arranged case cases, are attached to the longitudinal ends of the two shutter cases. Attach each side of the base cloth that can be expanded and contracted by providing a margin for closing the gap, or a chuck with an elastic member such as a bellows, or a connection type seal member such as a seal chuck. It is formed so that both can be easily connected and can be detachably formed so that a seal for keeping cold can be surely performed.

Further, in the present invention, the opening and closing of the shutter is performed by a sliding door type horizontal sliding system, and a predetermined opening is provided over a front opening, a side plate, and a back of each of the continuously installed cases. Long guide rails may be provided at the top and bottom, and between these rails, the main body surface of the shutter may be slid in the horizontal direction while being upright, so that storage and pull-out can be performed. The operation of driving the shutter can be performed manually or electrically.

[0007] Therefore, the present invention is configured as described above, so that it is compared with a conventional film-shaped night cover.
The cooling performance of the shutter itself can be improved, and the cooling performance of the shutter can be improved by about 300% by using a structure in which the shutter is almost sealed, and even compared to the existing optional sealed type. Since the present invention has an integral structure from the initial design, it is an extremely smart closed refrigeration show.
The case can be formed, and the opening and closing operation is simple, so that maintenance is easy and the shutter is housed in the extended state. It is possible to solve the problems on hygiene management which has been a concern in the past, and it can be an effective means of countermeasures for global environmental problems by saving electricity costs and saving energy as well as the cost advantage of the equipment. .

Things. When the main body of the case is manufactured, the shutter opening / closing device of the present invention is provided as a design structure and is simultaneously assembled and manufactured, so that it is much smarter than the optional post-installation after installation in the store, and A large cost reduction becomes possible. In addition, since the storage structure of the shutter is a flat turn-in or sliding door type structure, it is possible to store the shutter in a state where the entire surface portion of the shutter is extended, and it is possible to dry dew condensation when storing the air. It is a very hygienic device, and it is also possible to reduce the condensation to zero by loading a sheet or fabric at a predetermined height below the shutter. Further, the airtightness is improved by using a fastener or a seal chuck having a structure capable of vertically connecting both end edges of adjacent shutters installed on a continuously arranged case. To improve the cooling performance,
Opening and closing operations can be facilitated, and workability at the time of opening and closing can be improved. By completely shielding the case opening, it is possible to contribute to the economic effect of enabling a significant reduction in power consumption, the saving of resources by energy saving and the response to global environmental problems. It is not necessary to move and display the displayed refrigerated food in the back yard when the store is closed, and it is possible to improve the shelf life of daily fresh food stored in the showcase.
