[0010]

According to the first aspect of the present invention, there is provided an electromagnetic valve which is kept open by an electromagnet and a valve opening means for directly or indirectly pushing and opening the electromagnetic valve by opening the valve. It has a configuration in which a rubber buffering piece is provided in a part of the valve opening means, so that the impact force on the solenoid valve can be reduced.

According to a second aspect of the present invention, there is provided a slide and rotatable knob, an operation shaft provided on the knob, a heating power adjusting means for sliding to change a gas amount,
A lever having a gear mechanism and a cam mechanism for transmitting the rotation operation of the knob to the sliding movement of the heating power adjusting means, and a spring piece for biasing the gear of the lever in a direction away from the gear of the knob are provided. With such a configuration, the frictional force of the gear can be reduced.

Further, according to the third aspect of the present invention, the front outer periphery of the knob which slides substantially perpendicularly to the operation panel is made thicker by one step, and the outer peripheral portion having a narrow inner portion is displayed for handling. Is located on the inside of the operation panel, and has a structure provided with operation means such that the knob pops out of the operation panel and the display surface appears during use.The outer periphery of the knob conceals a gap between the operation panel and the knob, and is used for ignition and The display is shown or hidden according to the fire extinguishing state.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. (Embodiment 1) FIG. 1 is a cross-sectional view of a gas cock device according to Embodiment 1 of the present invention, and FIGS. 2 (a) to 2 (d) are principle diagrams showing thermal power adjustment.

In FIG. 1, gas passages 4a, 4b, and 4c are formed in the cock body 1 including a lid in order from the inlet, and the slide closing member 2 is urged by a spring 11 through an orifice 8, and a shaft 6 is provided. By pressing the operating shaft 5 through the shaft, the shaft 2 slides in the axial direction, and the opening and closing of the gas passage 4c is adjusted by the hole 2a facing the gas passage 4c and the small hole group 8a of the orifice 8. Orifice 8
Is fixed to the cock main body 1 in a state of being pressed against the slide closing element 2 by a spring 11 in a flat plate shape.

On the other hand, when the solenoid valve 3 is mounted by being urged by a spring 12 and a button 18 directly connected to the operation shaft 5 is pushed in,
The rubber cushioning piece 15 press-fitted into the closing member 2 via the operating shaft 5, the shaft 6, and the closing member 2 pushes the solenoid valve 3 open, and the gas passage 4b is opened. Therefore, the button 18 is pushed in, and the cushioning piece 15 is
When pushing open, the impact force at the time of pushing can be reduced by the elasticity of the buffer piece 15. In addition, since the rubber cushioning piece 15 is press-fitted into the closing member 2, there is no gap and leakage of gas can be prevented. The electromagnetic valve 3 receives the thermal electromotive force of the flame or the like, and is electrically opened and held against the spring 12.

On the other hand, when not in use, the operating shaft 5 is held at a fire extinguishing position by a lock mechanism (not shown). If you push it in when extinguishing the fire, it will be locked in its original position. The thermal power is adjusted as follows. That is, the knob 21 provided on the outer periphery of the button 18 has the operation shaft 5 as a rotation axis and is linked with the lever 9 by the gear 24. The knob 21 makes the front outer periphery 25 one step thicker, displays heat power on the thinner outer periphery 26, and has a different color scheme from the front outer periphery 25. In the fire extinguishing state, only the front outer periphery 25 is operated. It is located on the front of the panel 22.

The shaft 6, which is configured to be pushed into the operation shaft 5, is urged toward the operation shaft 5 by a spring 14, and its operation is regulated by the operation shaft 5 in a fire extinguishing state and in a pushing operation, and in a combustion state, An axial displacement is regulated by a lever 9 via 7. The lever 9 rotates with the screw 20 as a fulcrum by the engagement of the gears 24 and 23 by the rotation of the knob 21, and as shown in FIGS. 2B to 2D, when the gas passage 4c is opened, the cam mechanism 9a is used. The shaft 6 and the closing member 2 are slid in the axial direction via a pin 7 attached to the shaft 6, so that the gas flow is controlled by the hole 2a of the closing member 2 and the small hole group 8a of the orifice 8. .

Further, when the fire is extinguished, when the operating shaft 5 is pushed through the button 18, the pin 7 and the shaft 6
Is pushed in, and conversely, the pin 7 returns to the initial position shown in FIG. 2A while rotating the lever 9 along the groove of the cam mechanism 9a of the lever 9. By this mechanism, the lever 9 is always held at a predetermined angle before the start of use, and can be set to a predetermined heating power at the next ignition. A leaf spring 10 is provided between the lever 9 and the bearing plate 19, and a gear 23 of the lever 9 is
In the direction away from the gear 24. Therefore, the frictional force of the gear portion can be reduced, and the operability is improved.

The arm 17 has a function of turning on and off the switch 16 in accordance with the movement of the operation shaft 5 in addition to constituting a lock mechanism of the operation shaft 5.

On the other hand, when the gas passage is closed, the knob 21 protrudes only from the front surface of the operation panel 22 with a single-step thicker outer periphery 25, and the displayed thin outer peripheral portion 26 is hidden inside the operation panel 22. In this state, the front outer periphery 25 plays the role of hiding the gap between the knob 21 and the operation panel 22 and preventing the display portion from being seen from the gap.

When the button 18 is depressed and the lock is released from the closed state of the gas passage, the button 18 and the knob 21 are integrally protruded toward the front, and the gas passage is opened. Part 26
Appears. With this display, the opening and closing of the gas passage and the strength of the thermal power can be clearly seen. When the button 18 is pushed in from the state where the gas passage is open, the button 18 is locked and closed.

In the above embodiment, the cushioning piece 15 is press-fitted into the closing piece 2. However, it is needless to say that the same function can be obtained by inserting the rubbery cushioning piece 15 in the middle of a rod such as the shaft 6. Nor.

[0023]

According to the gas cock device of the first aspect of the present invention, the following advantageous effects can be obtained.

(1) The destruction of the solenoid valve can be prevented by the buffer effect of the buffer piece. (2) The number of parts can be reduced, and the structure can be simple and inexpensive.

According to the gas cock device of the second aspect, the following advantageous effects can be obtained.

(1) It is possible to provide an inexpensive gas cock device having a simple structure and to save space because it is a slide type.

(2) Since the spring is mounted in a direction in which the gear of the lever is moved away from the knob, the frictional force of the gear portion can be reduced, and wear of the knob can be prevented.

Further, according to the gas cock device of the third aspect, the following advantageous effects can be obtained.

(1) Since the gap between the panel and the panel is hidden by the outer peripheral edge, the appearance is superior. (2) Since print display is performed on a portion one step thinner than the outer peripheral edge, fingers are less likely to touch during operation and dirt is less.

(3) When not in use, the display portion becomes invisible due to the outer peripheral edge portion, and when the device is used, the display portion pops out, so that the use state is clear at a glance, which is superior in terms of usability and safety.
