Description

[Detailed explanation of the idea] (Industrial application field) This invention relates to a shower unit.

(Prior Art) In conventional shower units, a hot water supply device is usually placed next to the main body of the shower unit.
The hot water supply equipment heats water introduced into the interior through a pressure reducing valve and a check valve from a water supply pipe buried in the surrounding wall of the installation location, and then supplies hot water to a hot water mixing faucet using a water supply pipe. In addition to the valves mentioned above, the equipment is equipped with a drain valve and a safety valve, and the hot water discharged when both valves are activated is sent to the outlet of the waterproof pan and drained.

In addition, each of the above-mentioned valves is installed close to the hot water supply equipment or near the inspection opening on the peripheral wall of the unit body, and connections during installation and repairs in the event of equipment or water leaks are performed through the inspection opening. The current situation is that

Water leaks are likely to occur from the above-mentioned valves or from the joints between the valves and pipes. If water leaks from each of the conventional valve parts, the area around the installation location will naturally become flooded and the problem will become uncontrollable. Further, when repairing or maintaining a water leak as described above, it is carried out through an inspection port inside the unit body, but the work is often time-consuming because the valves are scattered all over the place.

(Technical Issues) The above-mentioned problems are caused by the fact that conventional shower units and water heaters do not have any guarantee measures against water leakage, and the valves are scattered all over the place.

A technical object of the present invention is to provide a shower unit with a function of draining hot water spouted out from the valve portion without scattering it around the installation location, and to improve the maintainability of the valve.

(Means for solving the problems) The present invention takes the following measures to solve the above-mentioned problems.

An electric water heater is integrally installed on the ceiling wall of the shower unit body, and the valves connected to the water heater are gathered and arranged at an upper position in the unit room, and the valves are removably attached to the inner wall of the unit room. Cover with inspection cover.

(Function) The electric water heater, which is provided integrally with the ceiling wall, is held in the ceiling, which is an unused space, and supplies hot water to the water discharging device inside the main body. Further, the valves connected to the electric water heater are arranged together inside the unit room and covered with an inspection cover.

(Embodiment) An embodiment of the present invention will be described based on the drawings. In the drawings, A is the main body of the shower unit. The basic structure of the shower unit main body A is the same as that of a normal unit bath, and a peripheral wall panel 5 covers the space between the pillars 7 set up at the four corners of the upper edge of the waterproof pan 6 made of FRP, and the front A side peripheral wall panel 5 is provided with an entrance with a door 8, and a ceiling wall panel 1 is attached to the ceiling part.

A drain port 9 is provided at the bottom of the waterproof pan 6, and a hot water mixing faucet 10 and a shower 11 are provided on the indoor wall of the unit body A, and hot water is supplied to these by an electric water heater 2.

The electric water heater 2 has a substantially semi-cylindrical shape, and attached pipes 2a, 2 are provided on the bottom of the electric water heater 2 to communicate with the inside of the water heater 2.
Beams 12, 12' are formed by protruding beams a' and are fixed in parallel to the upper surface of one side of the ceiling wall panel 1.
is firmly fixed on top. In addition, the attached pipes 2a and 2a' protruding from the bottom of the water heater 2 are connected to the electric water heater 2.
When installed, it penetrates the ceiling wall panel 1 and projects toward the indoor side, and a pressure reducing valve 3a, a check valve 3b, a safety valve 3d, and a drain plug 3c are connected to the ends thereof, respectively. As a result, the valves 3 are arranged in a concentrated manner on the ceiling inside the shower room.

A large number of pipes are connected to the electric water heater 2 through respective valves 3. First, a water supply pipe 13a communicating with a water supply pipe buried in the surrounding wall of the installation location is connected to the pressure reducing valve 3a, and the pressure reducing valve 3a and the check valve 3 are connected to each other.
The water supply pipe 13b is guided from between the water supply pipe 13b and the water supply pipe 13b and connected to the hot water mixing faucet 10. Then, the drain pipe 13c is connected to the saucer 14 that receives the drain water from the safety valve 3d and the drain plug 3c, and the drain plug 1 at the tip of the pipe 13c is connected to the drain pipe 13c.
5 is projected into the room from the lower wall surface of the hot water mixing faucet 10 to allow drainage to flow into the waterproof pan 6, and a hot water pipe 13d from the electric water heater 2 is connected to the hot water mixing faucet 10. It is rational to centralize each valve 3 as described above because the drain pipe 13c can be shared. The above-mentioned pipes are arranged from each valve 3 and water heater 2 through the outer surface of the peripheral wall panel 5.

Each valve 3 exposed on the ceiling on one side of the shower room is covered with an inspection cover 4 as shown in the figure to maintain the beauty of the room.
By attaching it to the inner wall surface at point a, it can be easily removed for inspection.

When one of the above-mentioned valves 3 causes a water leak, hot water ejected from the valve flows out from between the inspection cover 4 and the surrounding wall panel 5, falls along the surrounding wall panel 5, and reaches the drain port of the waterproof pan 6. Water is drained from 9. However, even if water leaks from each of the valves 3, the leaked hot water is quickly drained from the drain port 9, so that the area around the installation location will not be flooded with water. Furthermore, since the valves are concentrated on the ceiling, repair and maintenance work is easy, and the usable space of the shower room is not narrowed by the accommodation space of the valves 3. Furthermore, since there is no need to provide an inspection port, the interior design can be easily integrated, and the fact that the drain pipe 13c can be shared as described above is effective for commercialization.

(Effects) Since the present invention is constructed as described above, it produces the effects listed below.

Since the valve connected to the water heater is placed inside the shower unit room, even if water leaks from the valve part, the hot water that gushes out will flow down into the room and be drained away by the unit room's drainage equipment. Therefore, even if water leaks from the valve portion, the area around the installation location can be prevented from being flooded with water.

Since the valves are arranged in a group in the upper part of the unit room, maintenance and inspection of the valves is easy and the available space in the room can be fully utilized.

Since the valve is covered with a removable inspection cover, the aesthetic appearance of the room will not be spoiled.
