BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage structure for an electric water heater.

[0002]

2. Description of the Related Art Conventionally, a unit frame 30 as shown in FIG. 7 is formed by a horizontal frame 30a and a vertical frame 30b, in which a main drain pipe 20, other water supply pipes 32, etc. are provided. It is an interior, and a front plate 31 is provided on the front surface of the unit frame 30,
A counter 33 is provided on the upper surface, and this counter 3
3, the washbasin 34 and the like are attached, and the electric water heater 1 may be installed in the unit frame 30. The drainage structure of the electric water heater 1 is shown in FIG. Is composed of. That is, the trap 7 is connected to the main drain pipe 20 separately from the trap pipe 21 for draining the basin 34 attached to the main drain pipe 20, and the trap 7 is drained from the electric water heater 1. The drainage is made to flow into the main drainage pipe 20 via the trap 7.

By the way, it is stipulated that a certain open space be provided in the drainage pipe for introducing the surplus water from the electric water heater 1 into the trap 7. That is, the main drain pipe 20
In the case of clogging, the drainage from the main drainage pipe 20 flows back through the trap 7 and flows into the electric water heater 1. In such a case, an extremely unsanitary situation occurs. It is stipulated that a certain open space be provided to avoid such a situation. However, in the conventional case, the electric water heater 1 is formed by forming a good open space.
There are various problems in constructing the drainage route, and in many cases, a sealed drainage structure is formed, and there is a problem that drainage flows back through the trap 7 and flows into the electric water heater 1.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems of the prior art, and an object thereof is to provide a drainage structure for an electric water heater capable of forming a good open space. The gist of the present invention is, in an electric water heater installed in a unit frame having a main drain pipe installed therein, a hopper connected to a trap connected to the main drain pipe via a pipe so as to be movable in position, and the hopper. And a tip of a drainage pipe of the electric water heater arranged above is fixed to an L-shaped metal fitting by forming a space, and the L-shaped metal fitting is fixed at a predetermined position of the unit frame.

[0005]

[Function] The hopper is attached to the L-shaped metal fitting, and the drain pipe of the electric water heater is connected to the upper part of the L-shaped metal fitting above the hopper to form a good open space between the tip of the drain pipe and the hopper. Therefore, the L-shaped metal fitting can be fixed and attached to a free position of the unit frame.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of a drainage structure of an electric water heater, and FIG. 2 is a perspective view of a main part. The electric water heater 1 is installed in the unit frame 30 as described above, and the drain pipe 2 is provided in the electric water heater 1 to discharge the excess water in the electric water heater 1 to the outside. This drain pipe 2 has a rubber grommet 10 on an L-shaped metal fitting 8.
It is attached via the drain pipe 2
The hopper 3 is attached to the L-shaped metal fitting 8 below by forming a space between the hopper 3 and the lower end of the pipe, and the pipe 4 is connected to the hopper 3 through the connecting tool 5, and the pipe 4 connects the connecting tool 6. The trap 7 is connected to the trap 7 via the main drain pipe 20 installed inside the unit frame 30 as described above.
Is connected to.

As shown in FIG. 3, if the pipe 4 is formed into a bellows-like pipe, the hopper 3 can be moved freely with respect to the trap 7, and the arrangement position can be freely selected. It is possible. A cap 7a is attached to the top of the trap 7 to cover it.

The L-shaped metal fitting 8 has a structure as shown in a perspective view in FIG. 4, and a horizontal flat piece 8b is integrally formed by horizontally bending the upper end of a vertical flat piece 8a. Cage,
The horizontal piece 8b has two grommet holes 8c, 8c formed therein. These grommet holes 8c, 8c
As described above, the tip end side of the drainage pipe 2 is attached via the rubber grommet 10 therein.

As shown in FIG. 2, a reinforcing tree 9 is provided inside the vertical piece 8a of the L-shaped metal fitting 8, and a screw 12 is screwed into the reinforcing wood 9 to fix the frame side metal fitting 11, and , The hopper 3 can be attached to the reinforcing tree 9 from the inside via a screw, and after the hopper 3 is attached,
The pipe 4 is connected to the hopper 3, and the pipe 4 is the trap 7.
Connect to. In that state, the frame side metal fitting 11 is hooked on the horizontal frame 30a of the unit frame 30, the rubber grommet 10 is inserted into the grommet holes 8c, 8c of the L-shaped metal fitting 8, and the drain pipe 2 is inserted into the rubber grommet 10 for drainage. An open space is formed between the lower end of the pipe 2 and the hopper 3 for installation.

By using the L-shaped metal fitting 8 as described above, an open space can be surely formed between the hopper 3 and the tip of the drainage pipe 2, and the position of the hopper 3 is moved via the pipe 4. Since it is possible, the L-shaped metal fitting 8 can be hooked and fixed at an arbitrary position of the unit frame 30 via the frame side metal fitting 11, and the mounting position of the piping member in the unit frame 30 can be selected. Become.

The L-shaped metal fitting 8 may have a structure as shown in FIG. 5, and the L-shaped metal fitting 8 in FIG.
Joining pieces 8d and 8d on both ends inside the vertical piece 8a, respectively.
Is fixed by spot welding or the like, and a hooking piece 8e that forms a hooking gap S with the vertical piece 8a is integrally formed on the upper end side of the joining pieces 8d, 8d. By doing so, the hopper 3 can be hooked on the hooking pieces 8e, 8e so as to be easily detachable. Therefore, when the L-shaped metal fitting 8 as shown in FIG. 5 is used, the L-shaped metal fitting 8 is fixed to a predetermined position of the unit frame 30 in advance, and the hopper 3 is moved to that position for easy mounting. Is something that can be done.

In this way, the drainage pipe 2 and the hopper 3 can be surely formed by forming the open space, and even if the main drainage pipe 20 is clogged and the backflow occurs through the trap 7 to the hopper 3 side. A backflow does not rise to the drainage pipe 2, and a sanitary and safe drainage structure can be provided.
