When the diaphragm (27) responds by detecting this flow of water, the water pressure responsive gas valve (33) opens via the valve shaft (34), and the gas in the gas flow path (31) is controlled by the gas control valve (35). Through the gas nozzle portion (36) and is supplied to the gas burner (9), where it is ignited by the ignition plug (37) and the gas burner (9) burns. The heat generated by combustion is heat-exchanged by the heat exchanger (10) and is discharged from the hand shower (20).

Next, when the battery case (11) is released, the battery case (11) is returned to the middle by a stroke restricting body (not shown) provided in the interlocking device (14) and locked at that position. At this time, the ignition switch (41) is turned off, but the hot water discharge switch (42) remains on, and the solenoid opening / closing valve (30)
Is supplied with a holding current by the electromotive force of the first thermocouple (38) from the control circuit (17), the electromagnetic opening / closing valve (30) is kept open, and the water shutoff valve (25) is also kept open. Locked,
Continue bathing.

To stop the hot water discharge, press the battery case (11) again and then release it to unlock the stroke restrictor (not shown), and the operation lever (12) and battery case (1
1) returns to the initial position, at which time the hot water switch (4
2) is turned off and the electromagnetic on-off valve (30) closes the gas flow path (31), and the interlocking device (14) operates in the return direction, and the water shutoff valve (25) closes the water passage (28). Gas burners (9)
And the combustion of the pilot burner (36) is stopped, and the hot water is stopped.

When using only water, when the hot water-water switch (16) is manually operated to switch to the water side, the signal is input to the control circuit (17) and control is performed even if the hot water switch (42) is turned on. Adsorption current does not flow from the circuit (17) to the electromagnetic release valve (30). If the battery case (11) is pushed here, the gas burner (9) will not burn and the water shutoff valve (25) opens the water channel (28) and only water comes out from the hand shower (20).

In addition, in FIG. 5, instead of the hand shower (20),
It shows another embodiment in which a conventional flexible hot water supply pipe (40) with a kitchen shower is connected to the hot water outlet (19).

According to this embodiment, the width (S) of the water heater body (1) is about 160 mm, which is smaller than the depth (T) of about 200 mm, so that the water heater can be used as a window of a kitchen or a washroom. Even if it is mounted on the upper wall surface, the area of the window closed by the water heater body (1) is extremely small, and it is possible to prevent the lighting of the room from being affected. Further, since it can be compactly attached to the upper part or one corner of the sink or the vanity, a sufficient washing area of the sink or the like can be secured, and the dishes can be efficiently washed.

Further, as shown in FIG. 3, the battery case (11), which is an operation body for performing hot water discharge and stop of hot water discharge by push operation, is rotatably pivoted at an appropriate position in the water heater body (1). The lower end of the operation lever (12) is extended to the lower position of the front cover (3) and is attached to the lower end of the operation lever (12). When the case (11) is pushed, there is no concern that the hand will slip and come into contact with the front cover (3) during the push operation, and the front surface of the water heater body can be prevented from becoming dirty during the operation.

Also, since the battery case (11) formed in a cylindrical shape is attached to the lower end of the operation lever (12) to form an operating body,
A battery case separate from the operating body is not required, which simplifies the configuration and also a battery case as an operating body (11).
Is below the front cover (3) and in the water heater body (1)
It is arranged in front of the bottom plate (4) of the vehicle and is in a position where the user can easily replace the battery.

(G) Effect of the Invention Since the wall-mounted type main stop type gas instantaneous water heater of the present invention is configured as described above, it has the following effects.

Since the width of the water heater body is smaller than its depth, the window area covered by the water heater body can be made smaller than that of the horizontally long one, and there is a concern that the lighting of a room such as a kitchen will be obstructed. In addition, it can be compactly attached to one upper corner of a sink or the like, and work such as washing of dishes can be efficiently performed.

The operating body that pushes hot water and stops tapping hot water is attached to the lower part of the operation lever, whose upper part is pivotally fixed in the water heater body and whose lower part is extended to the lower position of the front cover. Therefore, when operating the operating body with wet hands during work such as washing dishes, there is no risk of the hands slipping and coming into contact with the front cover during the operation, and the front of the water heater body does not get dirty during operation. Can be prevented.

Since the operating body is formed in a cylindrical shape and doubles as a battery case, not only can the operating body be made into a large shape for easy push operation, but also a battery case separate from the operating body is not required, which simplifies the configuration. , The number of parts can be reduced, and moreover,
By arranging the operating body, which also serves as the battery case, under the front cover, the battery can be easily replaced, which is excellent in usability.
