Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an open showcase having an automatic winding type night cover.

[0002]

2. Description of the Related Art Japanese Utility Model Publication No. 60-5348 (F25D
23/02), a cool air curtain is formed in the front opening of the storage chamber formed in the heat insulation wall, and a film of a self-winding winding type provided outside the upper part of the opening is provided outside the cool air curtain as necessary. In the open showcase that is attached to the cooler and the blower, it is opened on the low pressure side of the cool air passage that is on the windward side of the cooler and the blower and on the lee side of the suction port of the cold air curtain, and removes dew from the cooler and the film. A drainage hole for discharging to the outside is provided, and when the film is unfolded, the lower end of the film is located directly above the suction port, and is spaced inward from the inner surface of the front wall upper part of the heat insulating wall. There is shown an open showcase characterized in that the lower end of the film is positioned so that it is positioned in the suction opening.

[0003]

According to the above conventional technique, the dew treatment of the film surface and the attachment of the lower end of the film are excellent, but as shown in FIG. 4, the storage chamber is provided above the front wall 2A of the heat insulating wall. In the case where the transparent plate 16 which can be seen through and reduces the overflow of the cold air curtain A is provided, the locking tool at the lower end of the film 23 cannot be locked near the suction port 11, and therefore the suction port 11 An elongated stopper 19 is attached on the suction plate covering the cover, and the upper end of the stopper is attached to the transparent plate 1.
The structure in which the locking member 25 is locked by being positioned above the upper end of 6 has been adopted, but in such a structure, there is a problem that the stopper 19 partially deteriorates the see-through effect of the transparent plate 16, and There was a problem that the customer's clothes were caught in the stopper.

The present invention aims to solve the above problems.

[0005]

As a means for solving the above problems, the present invention is provided between a front wall having an opening closed by an air curtain and a front wall of a partition plate defining a storage chamber. A suction port that is formed to suck in the airflow that forms the air curtain, a sash that covers the upper edge of the front wall, and an automatic wind-up type night cover that is provided by being widened to the opening to cover the air curtain. A structure provided with an engaging member provided also at a pull-out end of the night cover, which also serves as a handle, and an engaging portion provided at a lower end of the engaging member and protruding forward so as to be engaged with a lower end of an inner wall of the sash. It was adopted.

[0006]

[Function] The night cover is fixed in a widened state by a simple operation of locking the forwardly projecting locking portion provided at the lower end of the grip of the night cover that also serves as the handle to the lower end of the inner wall of the sash. You can

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment will be described below with reference to the drawings. 1 shown in FIGS. 1 and 2 is an open showcase in which a main body is constituted by a heat insulating wall 2 having an opening 3 for storing and taking out products. A partition plate 4 is arranged at an appropriate distance from the inner wall of the heat insulating wall 2 to form a circulation passage 5 in which a cooler 7 and a blower 8 are installed, and a storage chamber 6 having a shelf 9, and Along the upper and lower ends of the opening, the outlet 10 and the inlet 1
1, the cold air heat-exchanged by the cooler 7, that is, the cool air is forcedly circulated by the blower 8 to form the low temperature air curtain A in the opening 3 to cool the storage chamber 6. 12
Is a drain hole formed in the bottom wall 2B of the heat insulating wall, located on the windward side of the cooler 7 and the blower 8 and on the leeward side of the suction port 11, that is, on the low-pressure side serving as the return area of the circulation passage 5. A drain pipe 13 for guiding the dew of the cooler 7 and the dew attached to the surface of the night cover, which will be described later, is connected to the outside. The suction port 11 is formed between the front wall 2A of the heat insulating wall 2 and the front wall 4A of the partition plate, and has a large number of suction ports so as to prevent products from falling into the circulation passage 5 through the suction port. It is covered with a metal suction plate 15 which forms 14.

Reference numeral 16 is a glass transparent plate which is erected on the upper portion of the front wall 2A, and is provided to reduce the overflow of cold air that reaches the suction port 11 through the opening 3.
Air curtain A due to the provision of this transparent plate 16
The refrigeration load at the opening 3 can be reduced even if the contact area between the air and the outside air is reduced. 17 is the transparent plate 16
The slender U-shaped sash that covers the upper edge of the transparent plate 16 functions as a handrail and also as a shock absorber for the upper edge of the transparent plate 16. Reference numeral 20 denotes a metal bumper rail provided on the upper portion of the front wall 2A, the lower end of which is connected to a front panel 22 which covers the front surface of the front wall 2A, and the upper end of which is the transparent plate 16 described above.
Are in contact with each other with an acute angle θ. That is, since the upper surface of the bumper rail is the inclined wall 21 with the front lowering, when the shock is applied, the upper end of the bumper rail is the transparent plate 1.
By sliding the surface of 6 upward, it is slightly deformed to absorb the impact.

Reference numeral 23 is a flexible plastic sheet or film or the like, and the upper end serving as a fixed end is provided outside the upper part of the opening via a support tool 24. With a pull-type night cover, the grip 25 also serving as a handle provided at the lower end serving as a drawer end is pulled downward as needed when the store is not operating, such as at night. As shown in FIG.
By locking the locking portion 25A provided at the lower end of the sash 17 to the lower end of the inner wall of the sash 17, the opening 3 provided outside the air curtain A is covered. In this state, the night cover 23 itself is not loosened because the automatic restoring force acts on the night cover 23.

As the sash 17 is capped on the upper edge of the transparent plate 16 via the packing 30 made of rubber or resin, a gap is formed between the lower end of the inner wall 18 of the sash 17 and the inner surface of the transparent plate 16. The locking device 2 of the night cover 23 formed
5 can be locked to the lower end of the inner wall 18. An electric heater 31 heats the sash 17. According to such a configuration, the transparent plate 16 has an upper end located above the suction port 11, and therefore has a function of preventing the diffusion of the cold air that reduces the flow velocity of the downstream of the air curtain A and guiding it to the suction port.
As a result, the transparent plate 16 prevents contact between the cool air downstream of the air curtain A, which is a turbulent region, and the outside air, and the refrigeration load at the opening 3 can be reduced.

Further, since the sash 17 crowning the upper edge of the transparent plate 16 acts as a stopper for locking the locking member 25 of the night cover 23, locking by providing the transparent plate 16 is performed. It is possible to eliminate the adverse effect of the operation of the tool 25.

[0012]

With the above construction, it is not necessary to provide a special stopper on the sash, and it is possible to prevent a customer or an employee from being accidentally injured by the stopper.
With the night cover expanded, the night cover can be fixed by a simple operation of locking the locking part that is provided at the lower end of the locking device that also functions as a handle and projects forward to the lower end of the inner wall of the sash. .
