Description

[Detailed Description of the Invention] The present invention relates to an improvement in the drainage structure of a freezer/refrigeration showcase that is used in conjunction with a plurality of display cases.

Generally, when a plurality of frozen/refrigerated showcases are installed in a supermarket or the like, one problem is what to do with the waste water generated in each showcase.

Up until now, as shown in Figure 1, a drainage ditch 2 was created in the floor during the foundation work to create a store, and a drainage pipe 3 was led out from the drainage port of each showcase 1 to drain water. As shown in Figure 2, a main drain pipe 4 is buried in the floor in advance, a riser pipe 5 is erected at the planned location of the showcase, and the drain pipe of the corresponding showcase is connected to this riser pipe 5 to drain water. Ta.

However, requiring such foundation work throughout the store is not desirable as it will require a large amount of construction costs, and since the installation positions of the showcases are determined in advance, it is difficult to significantly change the positions.

In contrast, with this invention, even when installing a large number of frozen and refrigerated showcases, there is less work required to install drainage ditches or drain pipes in these installation areas, and it is relatively easy to change the installation location of each showcase. The purpose of this project is to provide a freezing/refrigerating showcase equipped with a drainage mechanism that can be used in various ways.

The present invention allows the main drain pipe or drain pipe provided in a part of the installation area of the showcase to be shared with other showcases.

Examples of the present invention will be described below.

FIG. 3 is a diagram showing the bottom of the freezer/refrigerator open showcase according to the present invention, which is the same as the conventional one except for the six approximately T-shaped drain pipes, and is used by connecting a plurality of them in the longitudinal direction.

This T-shaped drain pipe 6 is attached to a drain outlet provided on the bottom insulating wall, but in consideration of repairs after delivery, both branch pipes are attached to the front side of the case, and the main pipe section A part of the material is flexible and stretchable, for example, soft PVC resin,
It is composed of a flexible tube 61 made of resin-impregnated cloth or the like.

In addition, both branch pipes of the T-shaped drain pipe 6 can be connected to each other by a drain pipe 7 for connecting with an adjacent showcase, as shown by the two-dot chain line in the figure. A drain pipe attached to the showcase adjacent to the other end can be connected directly or via a flexible pipe similar to the flexible pipe 61.

Figure 4 shows the connection structure of each drain pipe when multiple freezer/refrigerated open storage cases are connected in series, as seen from the front with the decorative panel removed. They are connected in series via pipes 8 so that drainage from each showcase can be led to a main drain pipe 4 buried in the floor.

Branch pipes of the T-shaped drain pipe 6 to which the drain pipe 7 is not connected are closed with caps 9.

Reference numeral 10 denotes a drain pipe support, which is attached to the bottom insulating wall of the showcase with screws, etc. As shown in Fig. 4, the drain pipe 7 is raised as it moves away from the main drain pipe 4 to improve drainage. The mounting height of the support 10 can be changed in order to improve the quality of the support, and this will be explained with reference to FIGS. 5 and 6.

As is clear from FIG. 5, the height of the drain pipe 7 is located below the lower surface of the bottom insulating wall at the rising part of the bottom insulating wall in order to improve drainage.

However, normally, a refrigerant compressor, condenser, etc. for cooling are housed in a unit type in the lower area of the bottom insulation wall, and can be pulled out to the front of the case for repairs, etc., and when pulled out, the drain pipe is removed. 7 and the support 10 become a hindrance.

In the present invention, this problem is solved by changing the mounting height of the support 10 and making the support height of the drain pipe 7 higher than the lower surface of the bottom insulation wall when pulling out the cooling unit.

That is, in FIG. 5, the position of the solid line indicates before the drain pipe 7 is connected, the position of the one-dot chain line indicates when the drain pipe 7' is connected, and the position of the two-dot chain line indicates the position before the drain pipe 7 is connected. It shows when the mounting height of the support 10 is changed.

FIG. 6 shows an example of a shape that allows the mounting height of the support 10 to be changed.

That is, an elongated hole 11 is provided in the main surface of the support 10, and a plurality of L-shaped notches 111 into which the mounting screws 12 can be inserted are provided at appropriate intervals along the entire length of the elongated hole 11. The installation height of the support 10 can be finely adjusted by simply loosening the support 10, and the cooling unit can be installed at the highest position when the cooling unit is pulled out.

As can be understood from the above explanation, freezing and
When using multiple refrigerated showcases in conjunction,
By connecting the shaped drain pipes 6 with a normal drain pipe 7, the waste water for 8 to 10 vehicles can be guided to the main drain pipe 4 at once, so it is not necessary to bury the main drain pipe 4 or create a drainage ditch. Construction costs can be significantly reduced.

Furthermore, even if the installation position of the showcase can be changed significantly, it can be easily changed by selecting the shape of the drain pipes that connect the T-shaped drain pipes.

Furthermore, we made a part of the main part of the T-shaped drain pipe flexible, and
The joints between the drain pipes that connect the shaped drain pipes are also made flexible so that the drain pipes can be easily lifted higher than the bottom surface of the bottom insulated wall. When the unit is a front drawer type, there is no obstruction to the drawer.

It should be noted that the present invention is not limited to the embodiments, and various examples can be considered especially for the structure for changing the mounting height of the drain pipe support.

Furthermore, the drain pipes can be connected to each other without using flexible pipes, and since the T-shaped drain pipe has a flexible pipe section, the mounting height of the support can be changed to raise the position of the drain pipes.
