(Utility Model Application Publication No. 119061/1983) (Problem to be solved by the invention) However, this device has the interlocking mechanism between these operating rods and the operators that operate them separately in relation to each operating rod. There is an inconvenience that assembly maintenance and the like for assembly are troublesome.

The object of the present invention is to obtain an instantaneous water heater that is free from such inconveniences.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a gas control member that is equipped with a gas on-off valve in the main body of a water heater that is equipped with a heat exchanger and a gas burner unit that heats the heat exchanger. and a water control member equipped with a water on-off valve and a water volume control valve, an operating rod connected to the gas on-off valve protrudes from the front of the gas control member, and an operating rod connected to the water valve on the front of the water control member. and a rotating shaft connected to the water flow control valve, and a first operator for operating the gas on-off valve which is pushed against a spring and is provided on a frame extending over the front surfaces of both control members; A lever that engages with the operator at one end and presses and opens the water on/off valve in conjunction with a push operation of the first operator, and a second operator that is detachably attached to the rotating shaft are assembled; The frame body is aligned by engagement between the rotating shaft and the second operator, and is attached to the front surfaces of both members.

(Function) This instantaneous water heater includes a first operator for operating the gas on-off valve, a lever that engages with the first operator at one end to press open the water on-off valve, and a rotating shaft. A detachable second operator is assembled in advance to a frame extending over the front surfaces of the gas control member and the water control member, and the frame is assembled to the rotating shaft protruding from the water control member and the frame. After engaging and aligning the second operator, the first operator can be attached to the operating rod protruding from the gas control member by simply assembling it to the front of the gas control member and the water control member using screws or the like. The operating rod protruding from the control member and the other end of the lever can be opposed to each other, making assembly extremely easy. Since the water on-off valve is opened and closed via a lever that is linked to the first operator, the frame can be made horizontally long with a small width from front to back, thereby making it possible to reduce the width of the water heater body. It is easy to assemble into a space.

(Example) An example of implementing the present invention will be explained with reference to the attached drawings.
In the drawing, 1 is the water heater main body, 2 is a heat exchanger installed in the water heater main body 1, 3 is a gas burner unit installed at the bottom of the heat exchanger 2, and 4 and 5 are arranged on the left and right of the bottom. shows a gas control member and a water control member,
The gas control member 4 has an operation rod 7 protruding from its front surface that is connected to the gas on-off valve 6 provided thereon, and the water control member 5 has an operation rod 7 that is connected to the water on-off valve 9 provided thereon on its front surface. The rod 10 and the rotating shaft 11 connected to the water flow control valve 8 are made to protrude. 12
1 shows a frame extending over the front surfaces of both the control members 4 and 5, and a first operator 14 for operating the gas on-off valve that is supported by the frame 12 and pushed against the return spring 13.
is engaged with the first operating element 14 at one end, and the operating element 1 is engaged with the first operating element 14 at one end.
A lever 15 that swings according to the pressing operation in step 4 and presses the water on-off valve 7 to open the valve at the other end, and a detachable second operator 16 are assembled to the rotation shaft 11, and the frame The body 12 is connected to the rotation shaft 11 and the second operator 16.
The frame body 12 is positioned and attached to the front surfaces of both members 4 and 5 by engagement with the members 4 and 5, and this will be explained with reference to the embodiment shown in the drawings. 12a and the connecting piece 1
It has a box-shaped configuration consisting of a rear plate 12b connected to the front plate 12a by 2c and 12c, and the first operator 1
4 is provided on the left side of the frame 12 so as to pass through the front and rear plates 12a, 12b and to be able to move forward against the return spring 13, and the first operator 14 is further provided with a push mechanism 17, As a result, when the first operation element 14 is operated for the first time, it is pushed from the start end position A to the end position B, and when the push operation is released, it is locked at the intermediate position C, and when the push operation is released for the second time, it is locked at the intermediate position C. When the pressure is subsequently released, the block 17a is returned to the starting position A, and the block 17a provided with the heart-shaped grooved cam of the push mechanism 17 is opposed to the operating rod 7 and is pressed. In the drawings, reference numeral 14a indicates a push button opposed to the front surface of the first operator 14. And the lever 1
5 is a vertical shaft 1 provided approximately in the center of the frame 12;
8 is provided in the frame 12 with an intermediate portion pivotally supported, and one end 15a thereof is engaged with the first operator 14, and the first operator 14 is rotated counterclockwise in conjunction with the return operation to the intermediate position. The other end 15b of the lever 15 facing the right side of the frame body 12 presses the operating rod 10 connected to the water on-off valve 9. To explain this in more detail, the engagement between the first operator 14 and one end 15a of the lever 15 is achieved by a spring 19 that is pivotally supported by a shaft 19a on a bracket 14d provided on the first operator 14.
This is done via the claw piece 19 that is fired counterclockwise at b. To explain this, the claw piece 19 is attached to the lever 1.
5 and a cam portion 19d that engages with a through hole 20 provided in the front plate 12a, and a cam portion 19d that engages with the through hole 20 provided in the front plate 12a.
It is provided so that its position is regulated by the upright piece 14b provided above.

To explain its operation, when pushing the first operator 14 from the starting end position A to the ending position B, the claw piece 19 is pushed by one end 15a of the lever 15 and moves clockwise against the spring 19b. When it rotates and is further pushed, the claw portion 19c eventually passes over the one end 15a and faces the back surface thereof, and when releasing the push operation of the first operator 14, one end of the lever 15 is attached to the claw portion 19c. 1
Return to the intermediate position with 5a locked. Therefore, the lever 15 swings counterclockwise about the shaft 18 and presses the water on-off valve 9 at the other end 15b to open it. When the first operator 14 is pressed for the second time, the first operator 14 returns to the starting position A, but the claw piece 19 has a cam portion 19d that is Fits into the through hole 20 and the cam portion 1
9d is pressed against the periphery of the through hole 20, and the spring 19b
The claw portion 19c and one end 15 of the lever 15 rotate clockwise about the shaft 19a against the elastic force of the lever 15.
The engagement with a is released. Therefore, the pressure on the water on-off valve 9 by the lever 15 is released, and the water on-off valve 9 is returned to its original position by the spring 9a to be in the closed state.

The second operator 16 is supported by the front plate 12a at the right end of the frame 12.
6 consists of a rotating shaft 16b equipped with a knob 16a at the front end that can be rotated, and the tip 16c of the rotating shaft 16b is inserted into the fitting hole 11a at the front end of the rotating shaft 11. By fitting them together, they are bound together. The second operator 16 is rotated between the water amount adjustment range and the "water position" outside this range, and when the second operator 16 is rotated to the "water position", the first operation is performed. The water on-off valve 9 can be opened by pressing without using the child 14.

For this reason, in the illustrated example, an arm 21 is provided which is pivoted on a shaft 18 that supports the lever 15 and faces the front surface of the lever 15, and a cam 22 provided on the rotation shaft 16b is rotated from the arm 21. A protruding piece 23 is provided that faces into the movement trajectory, and when the second operator 16 is rotated to the "water position", the protruding piece 23 is pushed to swing the arm 21, thereby causing the lever 1 to swing.
5, the water on-off valve 9 can be opened.

The frame body 12 has a second operator 1 at the "water position".
A locking member 24 is provided to lock the first operator 14 so that it cannot be operated when the first operator 14 is rotated. This prevents burning.

To explain this, the lock member 24 consists of a hook rod 24a slidably supported by the rear plate 12b and a hook hole 24b provided on the first operator 14, and is connected to the rear end of the arm 21. Projecting piece 25
When the second operator 16 is rotated to the "water position" by engaging with the first operator 16, the first operator 14 is pressed against the spring 24c and fitted into the hook hole 24b. Make it impossible to operate. Furthermore, when the first operator 14 is in the operating state, the second operator 16 is rotated to the "water position", which means that hot water is not dispensed even though the second operator 16 is in the "water position". I don't like it. For this reason, in the illustrated example, a swinging arm 26 is provided supported by the shaft 18, and one end 26a of the swinging arm 26 is engaged with a protruding piece 14c protruding from the first operator 14. When the operator 14 is pressed or held at the intermediate position C, the other end 26b faces within the rotation locus of the cam 22 and the second
Rotation of the operator 16 is prevented. In the above-described embodiment, the second operator 16 is configured to be rotatably operated, but as shown in the prior art example, this is a slider type that interlocks with the rotary shaft 11 via a rack and a pinion. Needless to say, it is possible to do this.

In the drawings, reference numeral 27 indicates a pin for fixing the rotating shaft 11 and the second operator 16.

(Effects of the Invention) According to the present invention, a first operator for operating the gas on-off valve, a lever that engages with the first operator at one end and presses the water on-off valve to open it; A frame body covering the front surfaces of the gas control member and the water control member is assembled in advance with a removable second operator on the rotation shaft, and the frame body is attached to the rotation shaft protruding from the water control member. After aligning the second operation rod assembled to the gas control member by engagement, the frame body is assembled to the front surface of the gas control member and the water control member using screws, etc., and the first operation rod protruding from the gas control member is attached to the frame body. The operating element, the operating rod protruding from the water control member, and the other end of the lever can be made to face each other, making it easy to assemble and remove. In particular, since the valve is operated via a lever that is linked to the first operator, the width of the frame can be made small, making it easy to assemble the water heater body into a limited space. It has the effect of becoming.
