Abstract

PURPOSE:To permit full automation of pouring water into a bathtub, additional heating and water discharging after bathing by a method wherein a water discharging three-way motor valve is arranged in a bath water circuit, arranged in a bath heater for heating water in the bathtub additionally, while an automatic hot-water feeding circuit and the bath water circuit are connected to the bottom of the bathtub. CONSTITUTION:Hot-water, heated to a given temperature by a hot-water temperature detecting sensor 4 and a control unit 9, is supplied automatically into the bathtub 1 from a hot-water heater 2 through an opening and closing motor valve 7 and the automatic hot-water feeding circuit 11. Hot-water, supplied to the bathtub 1, is sent into the bath heater 3 to heat up the hot-water in the bathtub 1 to the optimum temperature by a hot-water temperature detecting sensor 5. Remaining water in the bathtub 1 is discharged by switching the water discharging three-way motor valve 8, provided in the hot-water supplying circuit 10B for bath, to utilize the delivery force of the pump of three-way motor valve 8. According to this constitution, full automation of pouring water into bathtub 1, additional heating and discharging water after bathing may be accomplished.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a forced circulation bath water heater that fully automatically performs hot water supply, bath reheating, and drainage.

BACKGROUND OF THE INVENTION In recent years, forced circulation water heaters have automated everything from supplying hot water to bathtubs to reheating baths to bring them to a suitable temperature for bathing.

Hereinafter, an example of the conventional forced circulation bath water heater shown in FIG. 2 will be described with reference to the drawings.

In Figure 2, (1) is a bathtub, (2) is a hot water heater,
(4) The water heated to a constant temperature by the control device of the hot water temperature detection sensor A%+91 is opened by opening the electric on-off valve (7).
Hot water is automatically supplied to the bath (1) via the 0D automatic hot water supply water circuit. (3) is a bath heater, which sends the water supplied to the bathtub (fl) to the bath heater (3) using the pump (6) via the bath water circuit αq, and detects the water temperature in (5). Sensor B determines the appropriate temperature and boils the water in the bathtub (1).

In this way, in the past, everything from automatically supplying hot water to bathtubs to boiling them was automated.

Problems to be Solved by the Invention However, the above configuration is not completely automatic, but only automates the work up to taking a bath, and does not take into account the work after, that is, the work after bathing, and the drainage. Ta.

Means for Solving the Problems The present invention provides an automatic hot water supply circuit for supplying hot water between a bathtub and a hot water heater, and an electric on-off valve is disposed in the automatic hot water supply circuit to control the water in the bathtub. An electric three-way valve for drainage is arranged in the bath water circuit in which the bath heater for reheating is arranged, and the connection of the automatic hot water supply water circuit and the bath water circuit to the bathtub is provided at the lowest part (bottom), and the connection to the bathtub is provided. Everything from turning on the hot water, reheating it to bring it to the right temperature, and draining the water after bathing is fully automatic.

Effect of the present invention With the above-described configuration, the remaining water in the bathtub after bathing is discharged from the connection port provided at the bottom of the bathtub by the discharge force of the pump by opening the electric three-way valve provided in the bath water circuit. .

Embodiment An embodiment of the forced circulation bath water heater of the present invention will be described with reference to the drawings.

FIG. 1 shows the configuration of a forced circulation bath water heater of the present invention.

In FIG. 1, the same symbols as in FIG. 2 indicate the same parts.

The present invention is a conventional forced circulation bath water heater in which an electric three-way valve (8) is provided in the bath heated water supply circuit 10B of the bath water circuit OC.

Describing the operation of the forced circulation bath water heater of the present invention 0 Water heated to a constant temperature from the hot water heater (2) by the hot water temperature detection sensor A (4) and the control device (9) is heated to a constant temperature by the electric on-off valve (
7) and open the bathtub (
1) Hot water is automatically supplied. The water supplied to the bathtub (1) is supplied to the bath heater (
3), determine the appropriate temperature using the hot water temperature detection sensor 'v B t5+, and then switch the electric three-way valve (8) for drainage installed in the bath heating supply circuit 10B of the bath heating water supply circuit OI. By doing so, the remaining water in the bathtub (+1) is discharged from the connection port provided at the bottom of the bathtub (1) using the discharge force of the pump of the electric three-way valve (8).

As described above, according to the configuration of the present invention, it is possible to fully automate the process from filling the bathtub with water to reheating the bath to bring the bathing temperature to an appropriate temperature, and draining the remaining water after bathing.

Effects of the Invention As described above, the present invention has the following features: (1) As mentioned above, an electric on-off valve is provided in the bath water circuit to remove the remaining water in the bathtub after taking a bath, and a connection port on the bath side of the bath water circuit that connects the bath and the bathtub is connected to the bath water circuit. By installing it at the bottom of the bathtub, you can drain the remaining water in the bathtub after taking a bath by opening the electric on-off valve and using the discharge power of the pump. The process up to the subsequent drainage can be fully automated.
