Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to a low-temperature showcase in which a cooling chamber is formed below a storage chamber.

(b) Conventional Japanese Patent Application Publication No. 62-9511 (F25D23100) discloses a low-temperature showcase with facing plates, which has been widely used in stores in recent years. This low-temperature showcase has a transparent window on the front of the storage room and a pull-type transparent door on the back, and sales staff open the transparent door and take out products based on customer orders. In the storage chamber, shelves and a bottom plate are arranged to place products, and a cooling chamber containing an evaporator and a blower fan is formed below the bottom plate. In such a configuration, the storage of the product into the storage chamber is carried out by opening the transparent door in the same manner as the above-mentioned removal.

(c) Problems to be Solved by the Invention In the above-mentioned conventional technology, when displaying products on the bottom plate, the salesperson must bend down to store the products in the front part of the storage room where customers can easily see the products. In addition, in order to take the same bending posture when taking out the product,
Products will be displayed in the storage room starting from the area near the transparent door, which is easy to put in and take out.As a result, products will not be displayed at the front of the storage room where customers can easily see the products, and product sales will not increase. There was a problem.

Also, when performing maintenance inspections on the evaporator and blower fan in the cooling room,
Since the product is first removed from the bottom plate and then the bottom plate is removed, maintenance and inspection takes a long time and the work itself is complicated, so maintenance and inspection are not carried out, which makes the cooling room unsanitary. was there.

The present invention aims to solve the above-mentioned problems.It is an object of the present invention to make it possible to easily store and take out products from a storage room, and to display products in a position where customers can easily see the products. At the same time, it also facilitates maintenance and inspection of the cooling room.

(d) Means for Solving the Problems In order to achieve the above object, in the low temperature showcase of the present invention, both the front and rear bottom plates are arranged with a distance between them at the boundary between the storage chamber and the cooling chamber, and At least one of the two bottom plates is movable in the front and rear direction, and a stopper is inserted into the front and back bottom plates and the product placement plate placed above the gap and contacts either one of the bottom plates. This configuration allows the product placement plate to be moved back and forth within the range of the interval.

(*) Function In the above configuration, the stopper, which moves within the interval as the product placement plate moves, functions to restrict the movement of the product placement plate in the front and back direction, and its front surface is in contact with the rear surface of the front bottom plate. Sometimes, the forward movement of the product placement board is restricted and the product placement board is placed closer to the storage room, that is, the product is displayed and displayed, and the rear surface is in contact with the front of the rear bottom plate. Sometimes, the product placement plate is placed at the rear of the storage room by restricting its backward movement, that is, the product is stored or taken out.

Furthermore, since at least one of the front and rear bottom plates is movable in the front and back direction, when the front bottom plate is moved rearward to narrow the gap, the upper front part of the cooling chamber is largely opened.
Conversely, if the rear bottom plate is moved forward to narrow the gap, the upper part of the rear part of the cooling chamber will be wide open.
The range of communication between storage and cooling compartments is increased.

This extending portion (26) is formed with a stepped portion (27) for collecting dew from the first evaporator (20) and a plurality of small drainage holes (28) for allowing the dew from this stepped portion to drip downward. There is.

This drainage hole (28) is preferably formed in a portion of the blower fan which will be described later where the wind pressure is weak.

(30) and (31) are always operated, and the first. The cold air passing through the second evaporator (20) and (21) is routed as shown by the arrow in Figure 6: cooling chamber (3) - outlet (12) - storage chamber (2) - suction port (13) - cooling chamber (3). ) and a pair of first and second blower fans for forced circulation, both of which are attached to a box-shaped fan case (33) with a partition plate (32) in the center, as shown in Figure 8. . This first. 2nd double blower fan (
30) (31) is the length of the low temperature showcase (1), in other words, the length of the first. As the length of both the second evaporators (20) and (21) increases, the number of evaporators increases.For example, as shown in FIG. If the length of both second evaporators (20) and (21) is 6 feet, two pairs are used. (34) has a trailing edge that is the upper front edge of the first evaporator (20) and the first evaporator (20). Both second evaporators (20) (
21) is arranged so as to overlap the front edges of both the left and right tube plates (24), and can be fixed to both the tube plates (24) with fasteners such as screws. , the air inlet surfaces of both second evaporators (20, 21) and the extension (26) of the partition plate (22) are covered by this duct (34), while the inside of this duct is covered with the extension (26). ), the first air passage (3) faces the first evaporator (20).
