Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an ignition device for gas appliances mainly used for household use.

(Prior art) In order to simplify the operation, this type of device has an ignition operating member that is normally returned to the off position by a return spring, and is operated to the on position by an on operation against the return spring. A device is known in which the position is held by a lock member that snaps into engagement with the operating member, and the on position is released by moving the lock member with a release member.

(Problems to be Solved by the Invention) However, since the turning-on operation of the ignition operating member against the return spring is easy to operate, there is a problem of mischief by children.

(Means for Solving the Problems) The present invention is aimed at solving the above problems, and includes an ignition operating member for a gas appliance that is resiliently repelled to the OFF position by a return spring, and an ignition operating member that When the member is turned on against a return spring, the lock member snaps and engages the lock pawl with the stepped portion for holding the on position provided on the member via the spring, and the lock member comes into contact with the pressing piece provided on the lock member. In the ignition operation device for a gas appliance, the ignition operation member includes a release member for disengaging the lock pawl, and the ignition operation member is provided with an on-operation prevention step, and has an on-operation prevention step that engages with the step. A member is provided in conjunction with the throttle operation member of the gas appliance, and the lock member is provided with a second pressing piece that comes into contact with the throttle operation member to release the engagement of the lock pawl.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 indicates a gas appliance, and a fixed plate 2 on the front side of the appliance 1 has a pair of throttle valves in a gas passage 4 connected to a burner 3. Valve rods 6, 6 connected to 5, 5, and the valve rods 6,
6 is operated via rocking cams 6a, 6a which are pivotally supported on the fixed plate 2, and an opening/closing valve 8 provided in the gas passage 4 is opened, and a throttle operating member 7 is provided in the operating circuit of the igniter 9. An ignition operating member 11 for pressing the switch 10 is provided, and the member 11 is of a push button type and is slidably inserted into an operating case 12 provided at the front of the fixed plate 2, and is also provided between the fixed plate 2 and the ignition operating member 11. The interposed return spring 13 causes the on-position holding step 14 provided on the outer periphery to be resiliently attached to the front wall of the operating housing 12 and returned to the off position, and the intermediate portion of the operating member 11 is The member 1 engages with a blocking claw 24 to be described later.
A step portion 15 for preventing an on-operation is provided to prevent an on-operation against the return spring 13 of the first embodiment. Reference numeral 16 designates a locking member, which is pivotally supported by a shaft 18 in the operation housing 12 together with an on-position blocking member 17 superposed vertically thereon, and is rotated counterclockwise by a spring 19 wound around the shaft 18. The locking pawl 20, which is bent upward by the side surface of the operating member 11 when the operating member 11 is in the off position as shown in FIG. When the operating member 11 is in the on position, it is provided so as to engage with the stepped portion 14 of the member 11 to maintain the on position, and the locking member 16 also has a contact piece 29 provided on the side surface of the release member 26, which will be described later. a first pressing piece 21 that comes into contact with the locking pawl 20 to disengage the locking pawl 20;
The on-operation blocking member 17 is elastically repelled counterclockwise by a spring 23 suspended between it and the operation housing 12, and is provided with a second pressing piece 22 that releases the engagement of the on-operation housing 12. The blocking claw 24 bent to the operating member 1
A pressing piece 25 is provided so as to be detached from the stepped part 15 of 1, and further bent upward on the side surface thereof, so as to come into contact with the aperture operating member 7 and engage the blocking claw 24 with the stepped part 15. ing. 26 indicates a release member, and the member 26 is slidably inserted into the operation housing 12 parallel to the ignition operation member 11,
A step 28 provided on the outer periphery of the return spring 27 interposed between the fixed plate 2 is elastically locked to the front wall of the operation housing 12 and returned to the off position, and the lower surface thereof has the above-mentioned An abutting piece 29 that abuts the first pressing piece 21 is bent.

Next, the operation will be explained. As shown in FIG.
is pressed to rotate the member 17 against the spring 23, and the blocking pawl 24 is engaged with the stepped portion 15 of the ignition operating member 11, thus preventing the ignition operating member 11 from being turned on. Next, as shown in FIG. 3b, when the aperture operating member 7 is rotated to an appropriate aperture position, a spring 23 is applied to the blocking member 17 in order to release the pressure from the pressing piece 25.
The blocking pawl 24 is rotated by the step portion 15, and the blocking of the ignition operating member 11 from turning on is released, and then the ignition operating member 11 is moved against the spring 13 as shown in FIG. 3c. When turned on, the member 11 opens the on-off valve 8 and closes the switch 10 to ignite the burner 3. At this time, the lock pawl 20 of the lock member 16, which comes into elastic contact with the side surface of the member 11, engages with the stepped portion 14. The burner 3 continues to ignite, and the combustion of the burner 3 is stopped by pressing the first pressing piece 21 by pressing the release member 26 or by pressing the throttle operation member 7. The lock pawl 2 is rotated by the rotation of the lock member 16 against the spring 19 due to the pressure of the second pressing piece 22 due to the rotation to the OFF position.
The ignition operation member 11 is returned to its original state when the ignition operating member 11 is removed from the stepped portion 14.

(Effect of the invention) As described above, according to the present invention, the ignition operation member that engages with the lock member and maintains the on position when the ignition is turned on against the return spring is provided with an on-operation blocking step that prevents the on-operation. Since the on-operation preventing member having a blocking claw that engages with the stepped portion is provided in conjunction with the throttle operating member of the gas appliance, the on-operation of the ignition operating member is prevented by the throttle operating member. The ignition operating member is easy and safe to operate, and the ignition operating member is designed so that it can be released not only by the locking member that holds the ignition operating member in the on position but also by the throttle operating member in addition to the release member that releases the lock. This has the effect that the release operation can be used freely.
