Description

Description: TECHNICAL FIELD The present invention relates to a bathroom floor watering apparatus that heats a bathroom floor and heats the entire bathroom.

[Conventional technology]

In recent years, bathroom heating is gaining importance from the viewpoint of comfort and also from the viewpoint of health. However, in a bathroom, heating using electricity is difficult for safety reasons, and it has to be heated using hot water. Therefore, there are various heating systems using hot water, and various systems have been proposed. However, as shown in FIG. 6, Japanese Unexamined Patent Publication No. Sho 60-223923 discloses a method of warming the floor by spraying hot water on a washing area. In addition to a system in which a spout 11 is provided at the lower part of the wall as shown in the official gazette, a shower for washing the body in addition to a shower for washing the body as shown in FIG. 12
Has been proposed at a height.

[Problems to be Solved by the Invention] The system in which the spout 11 is provided below the wall shown in FIG. 6 has the following disadvantages.

1) Generally, the floor that needs to be heated most is the floor near the bathroom door. Therefore, the position of the spout 11 depends on the position of the bathroom door, and it is necessary to extend the hot water pipe 1 in accordance with the mounting position, which makes the piping work on site complicated and expensive.

2) Since the spout 11 is located at the lower part of the bathroom wall 9, a vacuum breaker, a hopper and the like are provided in the middle of the hot water pipe 1 in consideration of the possibility that the spout will be clogged and the spout 11 will be flooded. It is necessary to cut off the edge with clean water. Therefore, piping work becomes complicated and expensive. Also, the spout 11
If the water flows more backward, water leaks from the hopper or the like, and the reliability of waterproofing decreases.

3) Since the hot water is supplied from the hot water spout 11 provided near the floor, the hot water flows on the floor and flows to the drain in a short time.
Therefore, the floor can be heated, but the bathroom cannot be heated.

The system in which the shower 12 for hot water shown in FIG. 7 is provided at a high place has the following disadvantages.

1) When the shower 12 for hot water is installed in a bathroom of a general household, it is necessary to extend a dedicated pipe near the ceiling surface, which is a very complicated operation.

2) To attach the shower 12 to the bath unit, the lower body 13 to which the faucet 8 is usually attached and the bathroom wall 9 on which the shower 12 is provided are separately carried to the site and assembled. Therefore, the piping to the shower 12 for hot water can be performed only at the site, and the work at the site becomes complicated. In addition, since the piping is fixed to the back of the wall, an inspection port for maintenance and inspection must be provided on the wall 9, which is expensive, and a piping space is required between the bus unit and the building frame. Cannot be used effectively.

The present invention has been made in view of the above-mentioned drawbacks, and it is an object of the present invention to provide an inexpensive bathroom floor watering apparatus that can simultaneously perform floor heating and bathroom heating and that can be used together with a shower.

[Means for solving the problem]

The structure of the present invention for achieving the above object will be described with reference to FIGS. 1 to 5 corresponding to the embodiment. The present invention is connected to a hot water supply pipe (7) and a water supply pipe (6) and is internally provided. At least a water shutoff valve (8b) and a temperature control valve (8
In the faucet with shower (8) provided with a), an automatic temperature control valve (3) is provided between the hot water supply pipe (7) and the water supply pipe (6).
A hot water pipe (1) provided with a pipe water shutoff valve (2) is connected between the automatic temperature control valve (3) and the faucet water shutoff valve (8b). A technical measure is taken in which a shower (8e) is connected to the hot water pipe (1) between the pipe water shutoff valve (2) and the faucet water shutoff valve (8b).

[Operation] In the present invention, the pipe water shutoff valve 2 provided in the hot water pipe 1 is opened by turning on the switch 10 with the timer provided near the entrance of the bathroom by the above means.
Then, the water and hot water from the water supply and hot water supply pipes 6 and 7 flow into the automatic temperature control valve 3 provided in the bypass circuit 4 to automatically adjust the mixing ratio of hot and cold water to achieve the set temperature. At this time, since the faucet water shutoff valve 8b of the faucet with shower 8 is in a closed state, that is, a state in which the shower 8e is not used in the bathroom,
Hot water adjusted to an appropriate temperature by the automatic temperature control valve 3 flows into the shower 8e connected to the hot water pipe 1 through the water stop valve 2 for piping, and is directed to the floor below the shower head 8d whose wall surface is locked. Sprinkling hot water is performed.

The sprinkling water from the shower head 8d diffuses steam and scatters over a wide range of floors while heating the room, and flows to a drain while heating the floor according to a drain gradient. After a certain period of time, when the switch 10 with the timer is turned off, the pipe water shutoff valve 2 is closed, and the spraying of water from the shower head 8d is stopped.

Next, when entering the bathroom and using the faucet with shower 8, a general operation may be performed. That is, when the shower 8e is used, since the hot water pipe 1 for watering the floor is closed by the pipe water shutoff valve 2, the temperature control knob 8f of the faucet with shower 8 is set to an appropriate temperature, and then the Closing valve 8b
Can be switched to the shower 8e side, and when using the spout 8c of the faucet 8 with shower, a water shutoff valve knob for the faucet is used.
What is necessary is just to switch 8g to the water outlet 8c side.

Although the temperature setting of the automatic temperature control valve 3 is variable, it is preferably about 42 ° C. from the viewpoint of safety against burns when the switch 10 is turned on during bathing. Also, the setting time of the timer is appropriately about 3 to 5 minutes which is effective for floor heating and bathroom heating when the hot water is sprayed at about 42 ° C. But,
It varies slightly depending on the size of the bathroom or the material of the floor covering.
