Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a dishwasher that has a washing machine main body and a booster separately, and can be used either alone or in combination with a booster.

(Prior Art) A typical conventional under-counter type dishwasher for commercial use used in cafeterias, coffee shops, etc. has a structure in which a washing machine main body and a booster are separated.

This means that in places where hot water supply equipment is already installed, it is enough to connect the hot water pipe to the water supply port inside the washing machine, and a booster is not required.On the other hand, in places without hot water supply equipment, water is stored under heating. This is because the necessary amount of hot water must be secured by using the mechanism's booster.

(Problem that the invention aims to solve) By the way, conventional dishwashers of this type are tall enough to store the washing machine itself under the counter, and cannot be stacked vertically between it and the booster. In addition, the water inlet installed on the washer body side and the water inlet installed on the booster side are in different positions, so even if stacking is possible, the specifications of the piping connection work may be different. It was difficult to change.

Furthermore, there is the problem that the piping connection between the washing machine and the booster cannot be easily done if they are stacked one on top of the other.Therefore, it is necessary to install both side by side under the counter, which saves installation space. Occupying a wide area was also a problem.

The present invention was developed in response to the fact that the conventional products have various problems in practical use. By creating a structure that allows the piping connection between the two machines to be easily and rationally achieved without drawing it outward, we aim to simplify the work at the installation site and make effective use of the space under the counter. The purpose is to

(Means for Solving the Problems) As is clear from the drawings showing the embodiments, the present invention provides two pipe insertion holes 6 on the bottom surface of the casing 3 facing the machine room, and A washing machine main body 1 formed by a U-shaped pipe 5 to which a part of a water supply pipe 4 in a machine room is removably connected with a flare.
Two pipe insertion holes 12 are provided on the top surface of the casing 8, which has approximately the same horizontal cross-sectional shape as the cleaning main body 1.
A dishwasher is constituted by a booster 2 in which a water heating tank 9 having a water inlet 10 and a water outlet 11 is housed in the casing 8. It is something.

(Function) By making the booster 2 as flat as possible and having a low structure, it can be used as a stand for the washing machine main body 1, and when stacked vertically, it has two pipe insertion holes 6 and two pipe insertion holes 12. By overlapping, two connecting pipes, for example, a flexible hose, can be inserted through this portion to connect the water side pipe between the washing machine main body 1 and the booster 2.

Furthermore, by removing the U-shaped pipe 5 on the side of the washing machine main body 1 and connecting the two subsequent connection ports to the water inlet 10 and water outlet 11 of the water heating tank 9 with the flexible hose, pipe connection work inside the machine can be completed. All that is left to do is to connect the water pipe to the water supply port of the washing machine main body 1.

(Example) Figures 1 to 3 are schematic structural diagrams showing an example of the present invention in a separated state and in a stacked state in two layers, in which the washing machine main body 1 has a casing 3 divided into upper and lower parts. The upper part is used as a cleaning chamber, and the lower part is used as a machine room.

Removable legs 17 are attached to the bottom surface of the casing 3 at the four corners.

Reference numeral 4 denotes a water supply pipe, which connects a water supply port 14 disposed close to a hole 16 through which a water supply pipe or a hot water supply pipe is inserted in the machine room and a hot water storage tank 13 disposed at an upper part within the casing 3. , a solenoid valve 15 is interposed midway near the hot water storage tank 13.

The water supply pipe 4 is formed by a U-shaped pipe 5 which is removably flare-connected to a part of the piping in the machine room.

Next, the booster 2 has a low square box shape with a horizontal cross-sectional area approximately equal to that of the washing machine main body 1, and its height is approximately the same size as the legs 17.

As shown in FIG. 3, the booster 2 is used in combination with the washing machine main body 1 mounted as a stand, but usually it is a separate structure as an accessory to the washing machine main body 1. Two pipe insertion holes 12 are bored in the top surface of the casing 8 at positions that match the two pipe insertion holes 6 when stacked, and a water inlet 1 is further provided in the casing 8.
A water heating tank 9 having a water outlet 10 and a water outlet 11 on the same wall is housed in such a manner that both the ports 10 and 11 face the pipe insertion hole 12.

In addition, in the figure, 18 is an adjustment leg, 19 is a rubber packing, and 20 is an electric heater.

When installing the dishwasher with the above-mentioned configuration in a place equipped with hot water supply equipment, it should be installed at the bottom of the counter in the normal state with the U-shaped pipe 5 connected as shown in Figure 1, and the water supply port 14 The hot water supply pipe is connected to the

On the other hand, when using the washing machine main body 1 and the booster 2 in combination, as shown in FIG. Remove the flexible tubes 20, 20 made of edible annealed copper tubes and having flare joints into the pipe insertion hole 12.
connection port 7 after removing the U-shaped tube 5.
The water inlet 10 and water outlet 11 of the water heating tank 9 are brought into contact with each other by the flexible tubes 20 and 20, respectively.

In this state, the water supply port 14 is at the same position as in the stand-alone installation shown in the first figure, and by connecting the water pipe to it, no part of the connecting pipe is exposed outside the machine.

(Effect of the invention) As explained above, in this invention, the washing machine main body 1 and the booster 2 are used by stacking them vertically, so the installation space is the same as when the washing machine main body 1 is used alone, which saves space. is measured.

Also, since the connection piping between the washing machine main body 1 and the booster 2 can be made only on the inside through the pipe insertion holes 6 and 12, the external piping can be connected to the water supply (hot water) pipe as in the case of the washing machine main body 1 alone. Therefore, it can be installed closely against the wall.

Furthermore, since it is only necessary to prepare two short flexible tubes as auxiliary members, it is possible to save labor in on-site construction and provide a low-cost product.
