Abstract

PROBLEM TO BE SOLVED: To eliminate the need for going to a bathtub in order to confirm safety even when an aged person or a child is taking a bath. SOLUTION: When a call switch 26 of an outer input unit 25 disposed on the outside of a bathroom is depressed, an aged person or a child in the bathroom confirms an informing sound of an outer input unit 24 in the bathroom. Informing sound of the outer input unit 25 disposed on the outside of a bathroom is actuated by depressing a call switch 29 of the outer input unit 24 in the bathroom. Consequently, a person on the outside of a bathroom can be informed that no abnormality is present in the bathroom.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath water heater capable of hot water supply and additional heating of a bath.

[0002]

2. Description of the Related Art A conventional bath water heater has a configuration as shown in FIG.

Water passes through a water sensor 1 and a water temperature sensor 2 from a water inlet, absorbs heat in a hot water supply heat exchanger 3, passes through a hot water supply sensor 4 and a hot water supply control valve 5, and is discharged from a hot water outlet.
The gas passes through a hot water supply source electromagnetic valve 6 and a gas hot water supply proportional valve 7 from a gas inlet, and is burned by a hot water supply burner 8.

Bath water is supplied by a circulation pump 22 to a bath connection adapter 19, a return passage 13, a water level sensor 14, a switching three-way valve 15, a bath sensor 9, a water flow switch 10, a bath heat exchanger 11, an outgoing passage 12, and a bath connection. When the water circulates with the adapter 19 and the temperature of the hot water detected by the bath sensor 9 decreases, the gas passes through the bath source solenoid valve 16 and the bath proportional valve 17 of the gas, burns in the bath burner 18, and heats in the bath heat exchanger 11. To reheat the bath water.

When the hot water is supplied to the bathtub, the hot water that has absorbed heat in the hot water supply heat exchanger 3 passes through the hot water supply sensor 4 and the hot water supply amount control valve 5, the hot water supply electromagnetic valve 20, the cutoff valve 21, the access passage 12, and the bath water It passes through the return passage 13 and enters the bathtub from the bath connection adapter 19.

[0006] The operation modes such as hot water supply, reheating, hot water filling, etc., are input based on the information of the external input device 31 in the bathroom and the external input device 32 outside the bathroom that can display the operation status by inputting the setting of the operation mode. This is performed by control means 37 for controlling the operation mode. The external input device 31 in the bathroom is
As shown in FIG. 4, a switch 33 for inputting an operation mode such as “automatic bath” for filling with hot water, “batch-up” for reheating, and an external input device 31 in the bathroom to an external input device 32 outside the bathroom. It comprises a call switch 34 for sounding the alarm sound generator, a switch 35 for setting the set temperature and set amount of each operation mode, and a display unit 36 for displaying the operation state of each operation mode.

[0007]

In the conventional bath water heater, however, the call switch 34 of the external input device 31 in the bathroom is pressed to sound the notification sound generating device of the external input device 32 outside the bathroom, so that the bather can be bathed. Can send a signal to a person outside the bathroom, but for example, when the bather is an elderly person or a child, there is a problem that the bather must go to the bathroom to check the safety of the bather. In addition, there is a problem that a call cannot be confirmed for a hearing-impaired person.

[0008]

In order to solve the above-mentioned problems, a bath water heater according to the present invention is provided with an external input device outside a bathroom having a plurality of switches, a display capable of displaying a plurality of contents, and a notification sound generating device. When the switch of the external input device outside the bathroom is pressed, the notification sound generation device of the external input device in the bathroom sounds, and when the switch of the external input device in the bathroom is pressed, the notification of the external input device outside the bathroom is issued. It is provided with control means for controlling the sound generating device to sound.

According to the present invention, the safety of a bather such as an elderly person or a child can be easily confirmed without a person outside the bathroom going to the bathroom.
