Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a gas bath extinguishing push button device for remotely controlling the ignition and extinguishing of a gas bath.

Prior Art and Problems to be Solved by the Invention A conventional push button device for extinguishing gas bath points is disclosed in Japanese Patent Application Laid-open No. 1986-
As shown in No. 197531, a sub-button for pilot burner ignition, a main button for main burner ignition, and an extinguishing button are arranged side by side so that they can be pressed against spring elasticity, and on the bottom surface of these buttons, A sliding plate is provided which has three notched holes and is biased by a spring force to move in one direction along the direction in which these buttons are arranged, and corresponds to the sub-button by pushing the sliding plate. The main button includes a slope that engages with the edge of the notch hole to move the sliding plate in a direction that resists the spring force, and a hook that engages with the edge of the notch hole and holds it in the pressed state. In addition to the same slope and hook part as above, there is a blocking part at the lower end of the slope that hits the edge of the notch hole and prevents the main button from being pushed in before the sub button. The fire extinguishing button has a structure with only the same slope as above, and the pilot burner can be turned on by pressing the sub-button and locking its hook part on the edge of the notch hole to hold it in the pressed state. Open and ignite, then press the main button and hold it in the same pressed state to open and ignite the main burner, and to extinguish the fire, press the extinguishing button to move the sliding plate and press the main button. There are also known methods in which both buttons are returned to their original position by releasing the hook of the sub-button, but by moving the sliding plate along the direction in which the buttons are arranged,
Since the sub-buttons and main buttons are held in a pressed state and released from the pressed state, the sliding resistance between the sliding plate and the guide section is large, and force is required to push each button. In addition, because the sliding plate moves, extra space is required in the direction in which the buttons are arranged side by side, and the case that houses the device becomes larger in the direction in which the buttons are arranged in parallel, and the structure becomes complicated. can be.

A cam 42 is rotatably supported at its tip, and the cam 42 is rotated by the spring force of a torsion coil spring 43 which is attached between the cam 42 and the support part 40 and has a weaker spring force than the torsion coil spring 30. The rocking plate 2 whose lower end is as described above
The cam 42 is in contact with an engaging portion 45 formed at the right end of the cam 42, and on the right side of the cam 42 is a mainspring whose rotation center is an axis that is approximately along the direction in which the buttons 6, 7 and 8 are arranged side by side. The timer 47 is equipped with a spring force stored in a mainspring by rotating it clockwise when viewed from the right side of FIG. A pin 48 that can be engaged with the lower end of the cam 42 is provided protruding from the outer periphery of the surface of the timer 47 that corresponds to the cam 42 .

Next, the operation of this embodiment will be explained.

When the sub-button 6 is pushed against the spring force of the compression coil spring 9 from the state shown in FIGS. 1 and 2(a), the slope 31 engages in the first engagement, as shown in FIG. 2(b). The protrusion 22 of the member 21 is pressed, and the first engaging member 21 and the swinging plate 20 integrated therewith are pushed in while swinging clockwise against the spring force of the torsion coil springs 30 and 30a. Hook part 32
2, the lower surface 22a of the protrusion 22 of the first engaging member 21 touches the hook portion 3.
2, the sub-button 6 is held in the pressed state, the pilot burner on-off valve is opened, sparks are continuously generated from the spark generator, the pilot burner is ignited, and at the same time, the oscillating plate 20 is held in a state where it is swung at a certain angle clockwise, the second engaging member 24 is moved to its protrusion 25 as shown in FIG. 3(b).
After confirming that the pilot burner has ignited using the ignition confirmation indicator, the button 7 is kept separated from the blocking portion 34 of the main button 7 so as not to be able to engage with it.

When the main button 7 is pushed in against the spring force of the compression coil spring 10 from the state shown in FIG. 3(b), the slope 35 is pushed into the protrusion of the second engaging member 24, as shown in FIG. 3(c). 25, the second engaging member 24 is pushed in while swinging clockwise against the spring force of the torsion coil spring 30a, and during this time, the spring force of the torsion coil spring 30 acts on the swing plate 20. By doing so, the hook portion 32 continues to be locked to the first engaging member 21, and the sub-button 6 remains in the pressed state, and when the main button 7 is pressed, the hook portion 36 is engaged with the second engaging member. After passing the protrusion 25 of 24,
As shown in FIG. 3(d), the lower surface 25a of the protrusion 25 is engaged with the hook 36, the main button 7 is held in the pressed state, the main burner on-off valve is opened, and the main burner is ignited. The bath is boiled.

In the above ignition operation, when the sub-button 6 is not pushed in and the swing plate 20 is not swung against the spring elasticity, the second engaging member 24 moves as shown in FIG. 3(a).
As shown in the figure, the protrusion 25 has entered the lower surface of the blocking part 34 of the main button 7, so even if you try to press the main button 7 before pressing the sub button 6, the blocking part 34 will not protrude. It collides with the portion 25 and is prevented from being pushed in.

To extinguish the fire after the bath has been heated to the desired water temperature, push the extinguishing button 8 from the state shown in Fig. 4(a) against the spring force of the compression coil spring 11, and the fire will be extinguished as shown in Fig. 4(b). As shown in , the slope 38 presses the protrusion 29 of the third engaging member 28, causing the third engaging member 28 and the rocking plate 20 integrated therewith to rock clockwise, thereby causing the rocking. The first engaging member 21 integrated with the plate 20 swings in the same direction, and the hook part 32 of the sub-button 6 is released from the protrusion 22, and the swinging plate 2
0, the second engaging member 24 swings in the same direction, and the hook portion 36 of the main button 7 is released from the protrusion 25.
The sub-button 6 and the main button 7 are returned to their original positions by the spring force of the compression coil springs 9 and 10, respectively, the on-off valves of the pilot burner and the main burner are closed, and the fire is extinguished.
When the pressing force of the fire extinguishing button 8 is released, the extinguishing button 8 moves back to its original position by the spring force of the compression coil spring 11, and the rocking plate 20 and the second engaging member 24 are moved by the spring force of the torsion coil springs 30 and 30a. Return to the original position using force.

Further, in this embodiment, the fire can be automatically extinguished by operating the timer, and if the timer 47 is rotated counterclockwise in FIG. 5 to set the time, the timer 47 will gradually rotate clockwise to set the time. After a period of time, the pin 48 presses the cam 42, as shown by the chain line in FIG.
2 presses the engaging portion 45 of the rocking plate 20,
The rocking plate 20 is pressed in the same way as when the fire extinguishing button 8 is pressed.
is swung to return the sub button 6 and main button 7 to their original positions, and when the pin 48 passes the cam 42,
The swing plate 20 and the cam 42 move back to their original positions. Note that when the timer 47 is rotated counterclockwise in FIG. 5 to set the timer 47, the pin 48 suppresses the lower end of the cam 42 and
2 is rotated clockwise around the shaft 41, but since the swing plate 20 is not swung by the rotation of the cam 42, the sub-button 6 and main button 7, which have been pushed in, are moved back. Therefore, the timer 47 can be set at any time before or after pressing the sub button 6 and main button 7.

Further, in the above embodiment, the second engaging member 24 is formed separately from the swing plate 20 so that the sub-button 6 held in the pressed state does not move back when the main button 7 is pressed. When the main button 7 is pushed in, only the second engaging member 24 is swung to prevent the oscillating plate 20 from oscillating, but the second engaging member 24 is formed integrally with the oscillating plate 20. When the main button 7 is pressed, the swing plate 20
The protrusion 22 of the first engaging member 21 may also have a structure in which it swings.
By increasing the size of the part that is locked by the hook portion 32 and setting the size of the part that is locked by the hook portion 32 to be larger than the swinging dimension of the swinging plate 20 when the main button 7 is pressed, the sub-button 6 can be pressed when the main button 7 is pressed. It can be held in a pressed state, and also
If the opening/closing control means for the burner opening/closing valve is configured so that when the main button 7 is pressed, in addition to opening the main burner opening/closing valve, the pilot burner opening/closing valve is continuously opened. A structure may be adopted in which the sub-button 6 moves back to its original position when pressed.

Structure and Effects of the Invention As specifically explained in the above embodiments, the gas bath point extinguishing push button device of the present invention includes a sub-button for pilot burner ignition, a main button for main burner ignition, and an extinguishing button. The buttons are arranged side by side so that they can be pressed against the spring elasticity, and the buttons are arranged side by side to be able to swing around an axis parallel to the direction in which the buttons are arranged side by side, and the tips of the buttons are arranged side by side so that they can be pushed against the spring elasticity. A swinging plate is provided at a tip end of the swinging plate to which a swinging force is applied in a direction approaching each of the buttons.

A first engagement protrusion, a second engagement protrusion, and a third engagement protrusion are provided corresponding to the sub-button, the main button, and the extinguishing button, and the sub-button is provided with the first engagement protrusion. a slope that engages with a locking portion of the first engagement protrusion to allow the sub-button to be pressed while swinging the rocking plate in a direction that resists the spring elasticity; A hook portion that holds the button in a pressed state and holds the rocking plate in a state in which it is swung at a certain angle against the spring elasticity is formed sequentially in the pushing direction, and the main button is attached to the second engaging portion. a blocking portion that abuts against the mating protrusion and prevents the main button from being pressed; and a blocking portion that engages with the second engagement protrusion only when the swing plate is swinging at the predetermined angle or more. A slope that allows the main button to be pressed while swinging the rocking plate in a direction that resists the spring elasticity, and a locking portion of the second engagement protrusion to hold the main button in the pressed state. hook portions are sequentially formed in the pushing direction, and when the fire extinguishing button is pressed, the hooks engage with the third engagement protrusion and move the rocking plate in a direction that resists the spring elasticity. The gist is that a slope is formed for releasing the locking of the hook part to the first engaging protrusion and the locking of the hook part to the second engaging protrusion, By swinging the rocking plate provided on the side of each button around the @ line parallel to the direction in which each button is arranged, the sub button and main button can be held in the pressed state, or the pressed state can be changed. Compared to conventional devices in which these controls are performed using a sliding plate that moves along the direction in which each button is arranged, the oscillating plate does not have a sliding plate that moves the sliding plate. Since there is no dynamic resistance, each button can be pressed easily, and there is no need to provide extra space in the direction in which the buttons are arranged side by side, so the buttons can be made smaller in the direction in which the buttons are arranged side by side. Furthermore, the structure itself can be simplified.
