Abstract

PROBLEM TO BE SOLVED: To solve the problem of one having to go to a bathroom each time, to confirm the state of a person bathing in the bathroom. SOLUTION: When rise in the output signal of a level sensor is detected, the fact that a person is in a bathtub is indicated in the indicating unit 32 of an external input device 23 at the outside of the bathroom and the fact that a person is in the bathtub is transmitted by voice from a voice-generating device 33 every time, and then the output of the level sensor is not changed for a given period of time, until the output signal of the level sensor is lowered thereafter. When the voice in the bathroom, which is received from the receiving unit 29 of an external input device 22 in the bathroom, is at a given level or smaller, this indicates abnormality in the indicating unit 32 of the external input device 23 at the outside of the bathroom and the voice generating device 33 is controlled, so as to transmit the fact that the person is not being moved in the bathtub by voice, whereby the fact can be known easily by the external input device 23 at the outside of the bathroom by voice and the indication, when the person has become unable to move in the bathtub.

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.

The bath water is supplied by a circulation pump 9 to a bath connection adapter 10, a return passage 11, a water level sensor 12, and a switching device 3.
When the hot water temperature detected by the bath sensor 14 decreases, the gas circulates through the direction valve 13, the bath sensor 14, the water flow switch 15, the bath heat exchanger 16, the outgoing passage 17, and the bath connection adapter 10. After passing through the valve 18 and the bath proportional valve 19, the fuel is burned in the bath burner 20, the heat is absorbed in the bath heat exchanger 16, and the bath water is additionally heated.

When the hot water is supplied to the bathtub, the hot water absorbed by the hot water supply heat exchanger 3 passes through the hot water supply sensor 4, the hot water supply amount control valve 5, the hot water supply electromagnetic valve 21, the outgoing passage 17, and the return passage 11 of the bath. Then, the user enters the bathtub from the bath connection adapter 10.

The operation modes such as hot water supply, reheating, and hot water filling are based on information from an external input device 22 in the bathroom and an external input device 23 outside the bathroom that can input the setting of the operation mode and display the operation state. This is performed by the control unit 24 that controls the operation mode. The external input device 22 in the bathroom is
As shown in Fig. 4 (a), the bath is filled with hot water,
It comprises an automatic bath switch 25 for inputting an operation mode such as "reheating" for reheating, a refill switch 26, a display unit 27 for displaying an operation state of each operation mode, and the like, and an external input device 23 outside the bathroom. Is composed of a bath automatic switch 28 for inputting a "bath automatic" operation mode for filling with hot water as shown in FIG. 4 (b) and a display unit 29 for displaying the operation state of each operation mode.

However, in the conventional bath water heater, in order to check the condition of a person taking a bath in the bathroom, the condition cannot be checked unless the person goes to the bathroom. In the case of a child or a child, even if he or she cannot move in the bathtub, it has a problem that it is not immediately known.

[0008]

In order to solve the above-mentioned problems, a bath water heater according to the present invention, when detecting that an output signal of a water level sensor has risen, displays a display unit of an external input device outside the bathroom at regular intervals. In addition to displaying that there is a person in the bathtub, the sound generator sends a voice message indicating that there is a person in the bathtub and then the water level sensor until it detects that the output signal of the water level sensor has dropped. If the output of the bathroom does not change for a certain period of time and the sound in the bathroom received from the reception unit of the external input device in the bathroom is below a certain level, an abnormality is displayed on the display of the external input device outside the bathroom. Along with
A control means is provided for controlling the voice generation device to transmit by voice that a person is not moving in the bathtub.

According to the above invention, when a person taking a bath in a bathroom enters the bathtub and becomes unable to move in the bathtub, the external input device outside the bathroom automatically and easily recognizes the voice and display. Can be.
