As can be seen in the issue, there is a pressure switch located on the lower side of the water heater body that houses the heat exchanger and the burner unit below it, which is responsive to the push operation and is movable in the same direction as the heat exchanger. A control member is provided, so that a first push of the press operator causes the start of dispensing of hot water via a dispensing pipe extending downward from the main body, and a second push causes the dispensing of hot water to be stopped. The formula is known as follows.

(Problem to be solved by the invention) However, in this case, the operation knob for pressing the press operation element protrudes forward through the operation panel on the front of the water heater body, and thus the user cannot use his/her hands. Generally, the knobs are operated directly from the front, and if hands become dirty, the operating knobs become dirty, making the next operation uncomfortable.

Therefore, it is desired that the dirt can be easily washed away.

(Means for Solving the Problems) The purpose of the present invention is to obtain a device that meets these requirements. The control member is equipped with a control member that responds to a push-type push operation element, and when the push operation element is pressed the first time, the start of hot water dispensing is started via the hot water discharge pipe extending downward from the main body, and the second push is activated. According to the above-mentioned method, in the type that can stop the tap operation, an operation wire for operating the press operation element is connected, and a large ball-shaped or other operation knob is provided at the lower end of the wire. Become.

(Function) Next, to explain the function of the present invention, if you hold the operation knob and pull down the operation wire, the press operator will move 1
When the second push is given, the control member is activated to start dispensing hot water, and when the operator pulls down the operation wire by holding the operation knob operation wire again, the push operation element changes to 2.
When the third push is given, the tap stops, but when tapping the hot water, the knob can be moved to the side along with the wire if necessary and guided to the bottom of the tap at the lower end of the tap. Then, if necessary, the knob can be washed with hot water to remove dirt.

(Example) Embodiments of the present invention will be described with reference to the attached drawings.

In FIGS. 1 and 2, reference numeral 1 indicates a water heater main body, which houses an upper heat exchanger 2 and a lower burner unit 3 opposite thereto. A control member 5 that is movable back and forth in response to a front push-type pusher 4 is provided on its lower side, and when the pusher 4 is pressed for the first time, the hot water tap extends downward from the main body 1. Via the pipe 6 it was possible to obtain the start of the tap and then, by a second push, the stop of the tap.

In the illustrated example, the control member 5 is composed of a water valve 8 interposed in a water passage 7 connected to the heat exchanger 2 and a gas valve 10 interposed in a gas passage 9 connected to the burner unit 3. The operator 4 is equipped with a heart cam mechanism 11 and configured in a push-pull type.

In the drawings, reference numeral 12 indicates a knob for adjusting the temperature of hot water on the front side of the main body 1.

The above is not particularly different from what was proposed earlier, but
According to the present invention, an operation wire 13 extending longitudinally downward is directly or indirectly connected to the push operation element 4, and an enlarged ball-shaped or other operation knob 15 is provided at the lower end of the wire 13. By pulling the wire 13 downward through the knob 15, a predetermined push can be applied to the push operation element 4.

In the illustrated embodiment, the operating member 14 is connected to the wire 1.
3 and the push operation element 4 so as to be operated indirectly. That is, in the embodiment shown in FIGS. 1 to 3, the operating member 14 includes a first lever 14b that is pivotally supported on a shaft 14a extending longitudinally in the lateral direction so as to be tiltable back and forth, and the first lever 14b. A second lever 14c that swings up and down is pivoted on the water heater main body 1 side at one end facing the upper surface of the wire 14b, and the wire 13 is connected to the second lever 14.
The knob 15 at the lower end of the main body 1 hangs down from the tip thereof and extends longitudinally downward from the lower surface of the main body 1, and the knob 15 at the lower end is positioned further below when hot water is tapped. The length of the knob 15 is such that it can be placed under the tap hole at the lower end of the tap, so that when washing hands with hot water, the knob 15 can be washed at the same time to remove dirt. Further, the tip of the operating member 14c is formed into a tongue-shaped display section A that extends longitudinally in the vertical direction, and displays "stop" on the lower side and "open" on the upper side, so that both displays are displayed. It was selected and displayed in the display window 16 in front of it.

To explain its operation, if one end of the operating wire 13 is pulled downward using the operating knob 15 from the illustrated state, the push operating element 4 is given the first push via the operating member 14, and the control member 5 is It operates to start dispensing hot water, and the dispensing of hot water continues through the dispensing pipe 6 in preparation for hand washing and the like. At this time, the second lever 14c is kept in a downwardly moved state, and "open" is displayed on the display window 16. To stop the tap, hold the knob 15 on the wire 1.
All you have to do is pull 3 downwards again, and according to that,
The press operation element 4 is pressed a second time via the operation member 14, and the hot water supply is stopped. At this time, the second lever 14c is the first lever 14.
b is pushed up, and "stop" is displayed on the display window 16.

Thus, considering the case where hot water is continued to be dispensed through the hot water outlet pipe 6 in preparation for hand washing as described above, the knob 15 is moved to the side with the wire 13 as necessary when dispensing the hot water. The hot water can be guided to the lower side of the hot water outlet at the lower end of the hot water tap 6, and the knob 15 can be washed with hot water as necessary to eliminate dirt.

Incidentally, the operating member 14 is not limited to that of the above-mentioned embodiment, but may also be a boosting mechanism using water pressure as shown in FIG.

To explain this, a pin 14e that interlocks with a diaphragm 14d is provided on the front surface of the press operation element 4, and a pin 14e that is linked to the diaphragm 14d is connected to the upstream side of the water valve 8 via a valve 14g on the back surface of the diaphragm 14d.
A water pressure chamber 14i connected to the outlet 6 side via an orifice 14h is provided, and a cam 14j for opening and closing the water valve 14g is provided, and a wire 13 having an operating knob 15 at the lower end is connected to the cam 14j.

The cam 14j is provided with a spring 14k that always acts on the water valve 14g to open the valve.

In this case, when the operating knob 15 is pulled downward, the valve 14g opens and water is supplied into the water pressure chamber 14i, and the water pressure is used to apply the first push to the pusher 4 via the pin 14e. As in the above-described embodiment, hot water starts to be tapped, and hot water starts to be tapped through the hot water tap 6.

Incidentally, the cam 14j returns to its original position at the same time as the downward pull of the operating knob 15 is released by the force of the spring 14k, and the valve 14f is closed accordingly.
gradually eliminated through Therefore, the pin 14e returns to its original position. Then, to stop the hot water dispensing, the wire 13 should be pulled downward once again using the knob 15. Accordingly, the valve 14f will be opened in the same way as before, water will be supplied into the water pressure chamber 14i, and the water pressure will be Then, the push operation element 4 is pressed again via the pin 14e, and the tap water is stopped.

(Effect of the invention) As described above, according to the invention, by simply pulling the downwardly extending wire downward once by holding the operating knob at its lower end, the tapping of hot water can be started and then stopped in the same manner. This makes it simple and easy to use, and furthermore, the knob can be guided to the spout and cleaned if necessary, so it does not remain dirty after being operated with dirty hands. It has the effect of eliminating discomfort.
