Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air curtain in which cold air which blows downward from an upper front portion to form an air curtain is deflected rearward by a lower air guide provided in a lower front portion. Formula cold storage showcase.

[0002]

BACKGROUND OF THE INVENTION In the food dealer, for the display of frozen food is a commodity, is used Eyakaten formula refrigerated showcase the frozen food is tourists and clerk can be easily taken in and out is
There is.

[0003] Thus, the conventional refrigerated showcase smell
In order to display and replenish food, the food is placed on a transport cart in a separate refrigerated warehouse , and this transport cart is passed through the aisle in the store to the front of the refrigerated showcase.
Stop in (customer side), put on the shelves in the refrigerated showcase
Or, or, put the food directly to the display for the cart in a refrigerated warehouse, this display for the cart, and through the passage of the store, was on display in the closet from the front to the refrigerated showcase.

[0004]

When a transport cart is used, it takes a lot of time and time to transfer the food to the display shelves in the refrigerated showcase, which disturbs the customer's shopping and makes the customer feel uncomfortable. give.

[0005] The use of carts display, remove the air guide for Eyakaten which is provided on the floor bottom of the refrigerated showcase temporarily, after out the display cart is returned to the original position the air guide again need is, is cumbersome.

Further, in the conventional removable air guide, for the floor it is provided with projections for positioning the air guide, the projections, Tsu per the display cart casters
As a result, it is difficult to put the display cart in and out , and the food is exposed to the room temperature for a long time, so that the freshness of the food is deteriorated and it takes time to display and supplement the food, which hinders the customer's shopping.

On the other hand, if there is a step between the floor surface of the refrigerated showcase and the floor surface in the store, it is inconvenient because the step must be climbed when the display cart is taken in and out. An object of the present invention is to provide an air curtain type refrigerated showcase in which a display cart can be easily put in and taken out from the front without a step .

[0008]

To achieve the above object, according to an aspect of the present invention, the cold air forming the air curtain and ejected toward the front surface upper downward, provided on the bottom front Eaga
In the air curtain type refrigerated showcase that is deflected rearward by the id , the floor surface inside the air guide and the floor surface outside the air guide are the same.
It is a flat surface and the air guide is divided into multiple parts in the left-right direction.
In addition, the side edges of each divided part can be horizontally rotated.
The feature is that they are hinged to each other and can be opened and closed freely forward .

[0009]

[Action] in and out of the cart for display in a refrigerated showcase, not good just open the air guide forward. In this case, the floor on the inside of the air guide, since the floor of the outer are the same surface, and out of the cart for opening and closing the display of the air guide is easy. Once the display cart is in and out, the air guide need only be deployed to its original position and closed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show an embodiment of the present invention.
Is a refrigerated showcase, (1) is its side plate, (2) is the rear wall,
(3) is a food display cart.

[0011] On the inner side the upper part of the refrigerated showcase (A), is provided the refrigerator of the evaporator (4) is, at its rear fan facing forward (5), in front, the refrigerated showcase (A front of opening) (cold air outlet facing downward located at the upper end of the left face in FIG. 1) (6) are kicked set.

[0012] The front portion of the floor of the refrigerated showcase (A), the air curtain jetted downward from the air outlet (6) (18)
An air guide (7) that is long in the left-right direction is provided to deflect the cool air that forms the rearward direction.

As shown in FIGS. 2 and 3, the air guide
(7) is bisected into a right divided part (8) and a left divided part (9), and a baffle (8a) is provided on the upper surface and the rear surface of each divided part (8) (9). (9a) , and casters (10) on the bottom four corners
There has been kicked set. Total length of the left and right directions of the wedges (8) (9), are then from the distance of the opposing surfaces of the right and left side plates (1) and slightly smaller.

The right end of the front surface of the right divided portion (8) is fixed vertically to the front end of the right side plate (1) of the refrigerated showcase (A).
It is connected to the laterally elongated hole (12) in the left side piece of the end hinge (11) so as to be slightly laterally movable.

Proximal ends on the rear surfaces of the two divided parts (8) and (9) are hinged by a vertical central hinge (13) .
Proximal end portions of the front surface of the two divided portions (8) (9) is linked to detachment by from consisting latch (16) hook (14) and locking pin (15), is always both split portions (8) (9) is not able to relatively rotate around the central <br/> hinge (13), are arranged in a straight line.

The front left end of the left split portion (9) is attached to the front end of the left side plate (1) by the same hook as in the latch (16) .
(14) and engaged to be separable by the locking fitting consisting a locking pin (15) (17), the rotation of the air guide (7) is prevented.

The inside of the refrigerated showcase (A) is cooled in the evaporator (4) and sent by the fan (5) to blow out the air.
(6) and Ru is cooled by the cold air circulating in the arrow direction through the air guide port a (8a) (9b) of the air guide (7). Refrigerated showcase
The front of the (A) opening is an air curtain (1
By 8), the horizontal air flow is blocked and insulated.

The floor of the inner side of the air guide (7) in the refrigerated showcase (A) is put on the outside of the air guide (7)
It is on the same plane as the floor inside the store.

Display cart in refrigerated showcase (A)
To (3), to display or replenish food, latch (16)
Anchor fitting to the outer hook (14) of (17), as indicated by the imaginary lines and arrows 2, divided portion (8) of the air guide (7)
(9), after moving slightly in front towards while folding, is rotated in front of the side plates of the right (1) folded Bayoi. And <br/> for refrigeration since the front portion of the floor show the case (A) is opened, air or a basket (3) for display became scarce, carts for new display of goods are packed (3) and the can be easily and quickly replaced.

The folded collapsed min <br/> split portion of the air guide (7) (8) (9), by the above-described reverse operation, the front of the refrigerated showcase (A), in a straight line Ru can be fixed by expansion. Folding stand Mito rotation wedges (8) (9), the caster (10), can easily be performed.

In addition, each divided portion (8) of the air guide (7)
(9) in the, by providing the fan facing the rear, air curtain
The effect of (18) is further improved . When the front of the opening of the refrigerated showcase (A) is wide, or the casement of the air guide (7) is divided into three or more divided portions, or may be sequentially connected by their hinges each other.

[0022]

[Effects of the Invention] When the display cart is put in or taken out of the refrigerated showcase, it is not necessary to remove the air guide, and it is possible to easily move it to a position where it does not get in the way and open the passage, so that food can be put into the refrigerated showcase. , unobtrusive customer, also without Rukoto discomfort to the customer, quickly and easily, or can display or supplemented.
