Abstract

PURPOSE:To reduce the number of component parts, simplify an assembling work for the parts, provide a positive fixing of the parts and improve a stability of the fixed parts by a method wherein a damper rail is provided with a sealing mechanism for sealing around a supporting column and then the damper rail is fitted to the supporting column and a partition plate and fixed thereto. CONSTITUTION:Damper rails 22a and 22b are disposed in a communicating clearance 22 ranging from a right side end of a partition plate 21 up to a pair of forward and rearward C-shaped columns 23 and 24 so as to seal a spacing around the C-shaped columns 23 and 24 in a vertical direction. Since each of the damper rails 22a and 22b is set such that both longitudinal ends of each of the damper rails 22a and 22b are fixed to each of the C-shaped columns 23 and 24 and the partition plate 21, a positive fixing of each of the damper rails 22a and 22b is attained and at the same time its strength is further improved. Each of the C-shaped columns 23 and 24 are made such that a pair of C-shaped extreme ends 23a and 24a are fitted into each of corner cutout 31a of each of rectangular columns 31 so as to form a column.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) This invention relates to a cold room that cools an indoor room using a refrigeration cycle, a cold room that cools or heats the indoor room in a switchable manner,
The present invention relates to a showcase in which a hot switching chamber and a hot switching chamber are arranged side by side so as to communicate with each other in the vertical direction, and particularly to a showcase with an improved partition structure that partitions these two chambers.

(Prior Art) Generally, this type of showcase has a structure as shown in FIG. A built-in machine room 2 is provided, and a rectangular glass tubular showcase portion 3 is provided above the machine room 2.

The showcase part 3 has four pillars 4a, 4b, 4
Three of the four sides between C and 4d are fitted with transparent plate glass, and the remaining one side is formed into a rectangular tube shape with an upper glass door, and the interior can be cooled by a refrigeration cycle or heated by an electric heater. A cold/hot switching chamber 5 that can be heated and a cold chamber 6 exclusively for cooling are partitioned into upper and lower sections so as to be able to freely communicate with each other.

Conventionally, in this type of partition structure, four columns 4a to 4d are partitioned inwardly by a partition plate 7, and on the left and right sides of this partition plate 7, a pair of columns 4a and 4b, 4c and 4d, front and rear, are separated. The gaps between the damper 8 and the pair of corner partition plates 9a,
It is separated by 9b.

A pair of corner partition plates 9a and 9b are connected to a pair of front and rear supports in the showcase section 3, for example 4c, as shown in Fig. 8,
Semicircular notches 9 aa and 9 ba are fitted onto the outer peripheries of C-shaped pillar parts 4 ca and 4 da forming a part of C-shaped pillars 4 d, and are fixed thereto, thereby vertically partitioning the surroundings of pillars 4 c and 4 d.

Each left end of these pair of partition plates 9a, 9b and the partition plate 7
A communication gap 10 is formed between the cold and hot switching chambers S and the cold chamber 6 in the vertical direction. It is opened and closed by being slidably placed on a pair of front and rear damper rails lla and llb and moved in the left and right directions in the figure.

That is, when the cold/hot switching chamber 5 is in a cooling operation, the communication gap 10 is opened by moving the damper 8 and can communicate with the cold chamber 6.

(Problem to be Solved by the Invention) However, in such a conventional showcase, each corner partition plate 9a, 9b is provided for each of the pillars 4a to 4d, and in addition, these corner partition plates 9a, 9b and each damper rail lla , llb are separate bodies, so a gap is created between them and heat leaks occur.
a, 9b11a, and llb are downsized and the number of small parts increases.

Therefore, it is not easy to position each corner partition plate 9a, 9b and each damper rail lla, llb, and assembling these requires detailed manual work, which is not necessarily easy and reduces workability. This leads to high costs.

Moreover, each corner partition plate 9a, 9b has its notch 9aa,
The reliability of the fixation is low because it is fixed at almost one point by simply fitting the 9 ha onto each of the C-shaped pillars 4 ca and 4 da.

Therefore, this invention was made in consideration of such circumstances, and its purpose is to provide a showcase that can reduce the number of parts, simplify the parts assembly work, and reduce costs. .

[Structure of the Invention] (Means for Solving the Problems) This invention provides a conventional damper rail 11 with a corner partition plate 9.
It has the sealing functions of a and 9b, and is fitted and fixed to the conventional pair of support columns 4a to 4d and the partition plate 7 by a fitting structure, and is constructed as follows.

In other words, the present invention provides a cold/hot switching chamber for switchably cooling or heating the room, a cold room located below the switching chamber for cooling the room, and a cold/hot switching room and the cold room. a partition plate that partitions both chambers on the inside of the pillars; and a pair of left and right communication portions that are located on both sides of the partition plate and between a pair of mutually opposing pillars that communicate the cold and hot switching chambers with the cold chamber;
A pair of front and rear damper rails are sealed in the vertical direction around the pillars of these communication portions and are fixed by fitting into respective fitting portions of the partition plate and the pillars, and a damper rail that reciprocates on these pair of damper rails. The present invention is characterized by providing a damper that opens and closes a communication portion between the pair of damper rails.

(Function) Since the damper rail of the present invention has a function of vertically sealing around the support column, the conventional corner partition plate can be omitted, and the number of parts can be reduced. As a result, assembly work can be simplified.

Since this damper rail is fixed to the support column and the partition plate by fitting each other, the fixation can be ensured and stability is improved.
