Description

[Detailed Description of the Invention] The present invention relates to a front-open type freezing and refrigerating case equipped with a product display shelf.

Generally, this type of case is called an open case, and many have a structure as shown in FIG. 1 in principle. To explain this simply,
This case has a large opening on the front side, so an inner box 2 is provided at a certain interval inside the heat insulator 1 forming the outer case, and these spaces are used to open the back part from the bottom of the case. A ventilation path 4 is formed by a fan 3 that extends through the ceiling and reaches the ceiling, and an air curtain 5 is formed at the openings on the front side of the ceiling and the front side of the bottom to circulate the ventilation, thereby blocking the inside and outside of the case. Refrigerant evaporator 6 for cooling inside
By cooling the ventilated air, the inner bottom of the case and the products on the product display shelves 7 are cooled.

Since the front of the case is always open, products can be taken in and out freely, which is convenient especially when there are many customers.However, on the other hand, insects and relatively large debris can pass through the air curtain 5 and enter the case. There is a problem that it is not desirable in terms of hygiene management,
In addition, since cold air generally stays at the bottom of the case, there is also a drawback that the cooling effect on the products on the product display shelves 7 at the top of the case is not as good as that at the bottom of the case.

The purpose of this invention is to provide a frozen/refrigerated open case that can prevent dust and insects from adhering to product display shelves.

Another object of the present invention is to provide a frozen/refrigerated open show case that can improve the cooling effect on products on product display shelves.

Examples of the present invention will be described below.

FIG. 2 shows an embodiment of the present invention in terms of a product display shelf, in which a cover storage frame 11 for storing a transparent sheet-like shelf cover 10 that covers a certain space on a product display shelf 7 is secured with screws. A cover frame 20 is attached to the inner box panel 2 and has frames 21 on both sides, which guide the end of the shelf cover 10 and restrict the space to be covered by the shelf cover 10, on the product display shelf 7. It has been placed.

Among these, the shelf cover 10 is schematically shown in FIG. 3, and is equipped with a winding mechanism using a rotating shaft 12 and a spiral spring 13 in the cover storage frame 11, and has small cuts on both sides at the end of the winding. A cover hanging rod 14 is attached with a notch provided. Further, a plastic film such as a hard polyethylene sheet is used as the material, and a large number of small holes are provided over the entire surface of the plastic film.

On the other hand, the cover frame 20 is schematically shown in FIG. 4, and has a cover guide frame 21 on both sides of the frame extending over the periphery of the product display shelf 7. A claw 22 is provided that can lock the hanging rod 14 in the notch of the shelf cover 10.

These are installed on each product display shelf in the case as shown in Figure 2, and when the store is closed or products are not being taken out or taken out, the shelf cover 10 is placed in the cover storage frame 1.
By pulling it out from 1 and hanging it on the lowest claw 22, the top of the product display shelf 7 is covered with the shelf cover 10, and when you want to take out or put in products, the shelf cover 10 can be moved to the middle or middle level depending on the position. The shelf cover 10 can be hung on the upper claw 22 or returned to the cover storage frame 11, and this operation can be performed with a single touch since the shelf cover 10 is always urged in the winding direction by the winding mechanism.

In this way, in the present invention, when products are not being taken out or put in, the product display shelf is covered with the shelf cover 10, and except for a small gap at the front end of the shelf, the side surfaces are covered with or adjacent to the side plates of the case. Since it communicates with the space provided by the shelf cover provided on the display shelf, relatively large dirt or insects will not enter, and a favorable effect in terms of hygiene management can be obtained.In terms of appearance, the shelf cover 10 is transparent so that the products inside can be seen. be able to.

In addition, the shelf cover 10 is provided with a large number of small holes, so that there is a gap at the front end of the product display shelf even when the shelf cover 10 covers the product, so the cooling effect is not reduced. Then further,
As shown in FIG. 2, the inner box panel 2 between the product display shelf 7 and the cover storage frame 11 is provided with a plurality of small holes 8 for blowing out cold air at intervals in the width direction. Cool air is always blown upwards, providing a good cooling effect, and especially when covered with the shelf cover 10, the cool air stays in this space, which further improves the cooling effect.

As a result, it is possible to set cooling spaces with different temperatures for each display shelf in the case between the display shelves covered by the shelf cover 10 and the display shelves not covered by the shelf cover 10. Product (3-7℃) and ham,
This provides the advantage that processed meat products (0 to 2°C) such as sausages can be displayed in the same case.

Note that if the cover frame 20 is relatively heavy, such as a thick steel wire coated with vinyl or the like, the cover storage frame 11 may be assembled integrally on the cover guide frame 21 in advance, and the inner This is convenient because the installation work to the box panel 2 can be omitted.
