Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bathroom using a balanced bath pot or a balanced bath pot with shower (hereinafter referred to as a balance pot).

Traditionally, chimney-type bath pots were used as bath pots installed in bathrooms, but from around 1962, bathrooms began to adopt balance pots with air supply and exhaust pipes as bath pots to be installed in bathrooms in order to improve safety. The number of plans has increased. However, in a bathroom system where a balance pot is installed, the bathtub inevitably becomes smaller. The area around the bathtub is difficult to clean and gets dirty easily. There is an image that appliances that use gas, called bathtubs, are dangerous in bathrooms, and in recent years there has been a growing need for clean, spacious bathrooms and safer bathrooms, and there has been a strong desire for improvements to gas appliances. Ta.

In response to such needs, outdoor pots or bath pots with outdoor hot water supply have been released, but their use has been limited to new construction or major remodeling of bathrooms. In addition, the majority of buildings that use balance pots are generally apartment buildings, and it is nearly impossible to make major bathroom remodels, so there is a strong need for products that meet the above needs without remodeling the building. It has been requested.

The present invention provides a method for installing a water heater or a water heater with reheating function by removing the balance pot and using the wall hole for the supply and exhaust pipe in a bathroom where a balance pot is installed and a wall hole for the supply and exhaust pipe is already made. The purpose of this project is to install a new bathtub or replace it with a larger bathtub to meet the need for a spacious bathtub, clean bathroom, and higher safety.

Embodiments of the present invention will be described below with reference to FIGS. 2 to 5.

1 is the bathroom. Reference numeral 2 designates a wall hole for mounting a supply/exhaust pipe 4, which was conventionally used for a balance pot 3. A water heater 5 connected to a gas pipe and a water pipe is installed and fixed in this wall hole 2, and is attached to the side wall of the bathroom. A remote control 6 is attached to the water heater to perform operations such as switching the capacity and/or adjusting the temperature of the water heater. The bathtub 7 is installed so that the upper edge of the bathtub 7 is in contact with the wall surface on the side where the water heater 5 is attached, and the water heater 5 is hidden or partially exposed.

In FIGS. 2 and 4, a mixer faucet with a faucet 8 and a shower 9 as end devices is attached to the upper edge of the bathtub 7, and the back side of the mixer faucet and the water heater 5 are attached to the upper edge of the bathtub 7.
are connected by piping. In addition, in FIG. 3, a piping operation box 15 equipped with a faucet 8, a shower 9, piping, etc. is arranged between the side wall 14 of the bathroom 1 and the bathtub 7, and the piping and power supply inside the box 15 are connected to the water heater 5. has been done.

In FIG. 4, piping 10 and piping 11 are connected from a water heater 5 to a bathtub 7, allowing high-temperature hot water to flow from the water heater 5 into the bathtub 7, and supplying hot water from the low-temperature bathtub to the water heater 5.
It is a circulation pipe that circulates and heats the
Reference numeral 12 denotes a water supply pipe that connects the water heater 5 to a mixing faucet on the upper end surface of the bathtub 7 and allows hot water of high temperature to flow from the water heater 5. Reference numeral 13 denotes a water supply pipe that allows tap water to flow into the mixing faucet from the water main tap 16.

Figure 5 shows a hot water circulation type heat exchanger 1 installed on the side wall of a bathtub 7.
7 is attached and connected to the water heater 5, and the water heater 5 indirectly raises the temperature of hot water in the bathtub via the heat exchanger 17.

Therefore, the present invention provides a bathroom in which a bathtub is placed in a room with a hole in the wall for the supply and exhaust pipe of a balance pot, a water heater installed in the hole in the wall, and terminal equipment and equipment installed in the bathroom or bathtub. Or, since the bathtub and the water heater are connected by piping, the following effects can be achieved.

(1) Since the bathroom can be used widely without remodeling the building, it can be replaced with a larger bathtub and the bathroom can be used effectively.

(2) Safety in the bathroom is increased because the water heater is installed in the wall hole where the supply and exhaust pipe is attached.
