The present invention mainly relates to a gas cock apparatus used in a table range.

In the conventional gas range and other equipment equipped with a small burner, the lower side of the gas cock of the type which ignites the main gas burner at the same time as the ignition, i.e., the rotation is freely accommodated in the cock body (a) shown in FIGS. 16 and 7. It opposes the spring (e) at the upper end of this closure (6) between the sieve (b) and the upper operation shaft (d) in which the cover plate (c) on the upper surface of the cock body (a) is freely inserted. Inclined cam surface (h) so that the projecting piece (g) protruding from the lower surface of the cover plate (c) is perturbed on the upper surface of the rotating cylinder (f). And a connecting body (j) having a freely lowered movement against the spring (i) against the spring (i) at the lower end of the operating shaft (d) in the rotation cylinder (f) and engaging with it without rotation. k) is engaged with the up-and-down end guide groove (ℓ) formed in the rotating cylinder (f) and rotated from the stop position of this operating shaft (d). In accordance with the operation, the projection k hangs on the lower end of the guide groove 1, i.e., the lower end l-1 of the rotation cylinder f, by the rotation operation from the stop position of the operation shaft d. The gas cock device, which is adapted to move the connecting body i downward by the downward movement by the rotation of the rotation cylinder f and the rotation of the rotation cylinder f, has been established in Japan. It is disclosed in the call publication.

However, it is possible to change the closing body only in two positions between the ignition position and the fully open position. In addition to this operation, there is a demand for a device capable of reliably positioning the closing body not only in the ignition position but also in the weak fire position which operates with a small amount of gas by allowing the switch to a weak fire (for example, moxibustion) position.

The present invention provides a gas cock that satisfies such demands, and includes a cock provided with an electromagnetic safety valve and a closing body in the cock body, and a cock provided with an operation shaft which is converted from the stop position (OFF) to the ignition position and the deployment position. Between the closure and the operating shaft, a rotational passage freely moving downward against the spring, and freely stopped by the rotational rotation, and freely and downwardly movable against the spring within the rotational cylinder. A connector is mounted on the shaft to stop rotation and stops. On the upper surface of the rotating cylinder, a connecting surface protruding from the lower surface of the cover plate slides, and at the same time, the connecting member is rotated by a protrusion on its outer side. Is stopped by the up-and-down longitudinal guide grooves formed in the upper and lower directions, and the projection is moved downward from the guide groove by turning from the stop position (OFF) of the operation shaft to the ignition position. Engaged with the end to open the valve by pressing the solenoid safety valve by the rotation of the rotating cylinder and the subsequent downward movement, and to operate the igniter before and after this, and release the operation of the operation shaft at this ignition position. When the operating shaft is rotated slightly by the return spring to be converted into the deployed position, the operating shaft of the operating shaft is configured to have a weak fire position at the operating position of the operating shaft so as to protrude the engaging piece from the connecting body, and also to walk from the cover plate. It is made by installing a bending piece facing the engagement piece at the telephone position with a gap larger than the thickness of the fitting piece, and installing the stopper portion facing the protruding piece on the cam surface when the operation shaft is operated to convert to a weak fire position. .

The operation of the present invention will be described with reference to the drawings.

When the operating shaft 5 is rotated from the fully closed position shown in Figs. 5 and 6 (a) to the ignition position, the connecting body 10 is first accompanied by the rotation, and the projection 14 is rotated. It is rotated through the connecting body 10 to the rotation cylinder 7 in the state engaged with the edge part 13a downward. In addition, since the projection tube 11 protruding from the cover plate 6 faces the cam surface 12 of the upper surface by the rotation of the rotation cylinder 7, the rotation cylinder 7 is accompanied by the rotation of the spring 8. The connecting body 10 also moves downward against the spring 9 through the protrusion 14 which is moved downward against the spring 13 and is engaged with the end 13a, and is in the state shown in FIG. . At this time, the closing body 4 is rotated by the rotation of the rotating cylinder 7 so that the ignition burner gas outlet, the main gas burner gas outlet 2b, and the weak insoluble gas burner shaft 2d are prepared in an open state. The igniter 16 is operated to open the valve by pressing the safety valve 3 by the downward movement of the connector 10, and the ignition burner is ignited.

Subsequently, when the operation shaft 5 is dismantled, the engagement with the end portion 13a of the projection 14 is released, and as shown in FIG. With the 10, it is moved upward by the spring force of the spring 9, and the pressing of the safety valve 3 is released. At the same time, the operation shaft 5 is shot upward by the spring 8, and the end portion 13a. The projection 14 is slid and moved to return to the deployed position.

The above operation is not particularly different from that disclosed in JP-A-58-93670.

The present invention provides a gap (L) larger than the thickness of the projection piece 20 from the cover plate 6 while installing the projection piece 20 protruding outward from the connecting body 10 in the above. Since the bending piece 21 which the projection piece 20 abuts at the said position was installed, when the operating shaft 5 was rotated from the stop position OFF to the ignition position, as shown in FIG. When the projection piece 20 touches the bending piece 21 and stops reliably, when the operation shaft 5 is released from the position, the engagement with the end portion 13a of the projection 14 is released as described above. As the connecting body 10 is moved, the contact between the bent piece 21 and the protrusion piece 20 is released as shown in FIG. This makes it possible to rotate the blocking body 4 at a larger angle by the operating shaft 5 and to rotate the operating shaft 5 to a weak fire position.

When the operating shaft 5 is rotated to this weak fire position, the protruding piece 11 abuts against the bending piece 21 of the stopper portion, and the operating shaft 5 reliably stops at that position. The gas outlet 2b is closed and becomes a weak fire state.

An embodiment of the present invention will be described with reference to the drawings.

And a cam surface 12 on which the protruding piece 11 projecting from the lower surface of the cover plate 6 slides on the upper surface of the rotating cylinder 7, The left and right pairs of upper and lower end binary guide grooves 13 having downward end portions 13a are formed on the side surfaces thereof, and the protrusions 14 protruding outward of the connecting body 10 are engaged therewith. The projection 14 is engaged with the downward end 13a of the guide groove 13 by the rotational operation from the stop position OFF to the ignition position, and thus the rotation of the rotation cylinder 7 The downward movement of the operation rod 15 penetrating through the closing body 4 causes the pressurization opening of the electromagnetic safety valve 3 and the igniter 16 provided on the cover plate 6 before and after. When operating and releasing the operation of the operating shaft 5 at this ignition position, the operating shaft 5 is a spring 8 provided between the cover plate 6 and the stopper funnel 17 on the operating shaft 5. Is rotated slightly to return to the deployment position.

The above structure is not particularly different from the conventional example, and the engagement for stopping the rotation of the connecting body 10 and the operation shaft 5 is formed in the tubular shape with the connecting body 10, and the projections 14 ) Is installed to penetrate through the connecting body 10, and a part of this protrusion 14 is engaged with the notch groove 5a provided in the lower part of the operation shaft 5, so that the rotation cylinder 7 and the closing body 4 It is also not particularly different from the conventional example that the engagement protrudes the water piece 7a downward from the rotation cylinder 7 and engages it with the longitudinal grooves 19 provided in the head portions on both sides of the closing body 4. not.

The present invention is configured to have a weak fire position and a weaker fire position (hereinafter, weakened position) at the operation position of the operation shaft 5 as described above, and at the same time, the projection piece 20 from the connecting body 10. ), And between the cover plate 6 and this, there is a gap L larger than the thickness of the projection piece 20, and the bending piece 21 which abuts at the ignition position is installed. When the operation shaft 5 is operated to convert to a weak fire position, a stopper portion 22 in contact with the protruding piece 11 is provided on the cam surface 12, which will be described below in detail with reference to FIG. 13. As shown, draw the ignition position at a position 115 ° counterclockwise from the stop position (OFF), and draw the deployment position at a position slightly below this, ie approximately 95 ° from the stop position (OFF). 55 ° advance from the stop position Set the weak fire position at the position of 150 ° less than 50 ° from the deployment position, that is, the weakest fire position at the position of 45 ° from the stop position, respectively, and ignite the operating shaft (5) from the stop position. When rotating to the position, the solenoid safety valve 3 is pushed open as mentioned above, and the closing body 4 also rotates along the operation shaft 5, and the gas inlet installed in the cock body 2 in the ignition position. (2a), the gas outlet 2b for the main gas burner, the outlet for the ignition gas burner 2c, the gas outlet 2d for the weak fire burner, and the like all communicate with each other as shown in FIG. 15 (b). , B, C) is supplied with gas, and all these burners A, B, and C are ignited by the igniter 16, and only burner A is extinguished in the deployment position. At the weak fire position, only the ignition gas burner A and the weak insoluble gas burner c are in a combustion state, as shown in FIG. 15 (c) in which the gas supply to the main gas burner gas outlet 2b is cut off. At the time of conversion to the weakening position, the gas amount at the outlet 2b for the main gas burner is brought into the combustion state shown in Fig. 15A.

The configurations of the gas outlets 2b, 2c, and 2d and the gas inlets 2a provided in the cock body 2 are as shown in FIGS. 1, 2, and 7 to 10, and the gas The inlet 2a and the gas outlet 2b form a large diameter first communication hole 4b branching from the main gas communication hole 2A formed in the closing body 4, and a small diameter second communication hole 4e. The gas inlet 2a and the weakly insoluble gas burner outlet 2d are made through an extremely small third communication hole 4d branched from the main gas communication hole 2A, and the gas inlet 2a and the ignition. The burner outlet 2c is made through the main gas communication hole 2A and the ignition gas communication hole 4c connected thereto, and the electromagnetic safety valve 3 is the gas inlet 2a and the main gas communication hole 2A. ) Was interposed between. And the electronic safety valve (3) is pushed open by the operation rod 15 in the ignition position as described above, and when the operation of the operation shaft (5) is released to return to the deployment position, the press is also released, but then ignition The valve opening is maintained by the electromotive force of the thermocouple (not shown) heated by the burner c.

The operation shaft 5 is regulated as described above at the ignition position and the weak fire position as described above, but the position control at the deployed position and the weakest fire position is not performed. For this reason, in the drawing, the click stop is applied at both positions via the click mechanism 23 between the operation shaft 5 and the cover plate 6. That is, on the operating shaft 5, as shown in FIG. 13, the rotating plate 25 in which the 1st, 2nd slits 24a and 24b which were inclined with respect to the radial direction was located by 180 degree inclination is provided. At the same time, the ball 26 moving along each slit 24a, 24b is provided, and the ball hole 27a, 27b and the 2nd which fitted the ball 26 in the 1st slit 24a on the upper surface are provided.

Is fitted into the ball hole 27c, but this time involves the ignition operation of the piezoelectric ignition device 16 described later, so that the ball 26 is rotated to the ignition position without the feeling of fitting the ball 26 into the ball hole 27c. At this time, the ball 26 stops at a position opposite to the point (a) of the spring plate 28, and then releases from the operating shaft 5 at the ignition position. Only the shaft 5 is returned by the clearance between (5) and (b). Subsequently, in this state, when the operation shaft 5 is rotated to the weakened position as shown in the drawing (b), the ball 26 in the first slit 24a is fitted into the ball hole 27c and positioned.

In addition, the igniter 16 consists of a piezoelectric device provided on the upper surface of the cover plate 8, and in this embodiment, a hammer that faces the piezoelectric element 28b by a cam plate 28a provided on the operation shaft 5. (28c) is to hit the piezoelectric element (28b) in the ignition position, which is the same as is generally known, and of course, it is possible to use an igniter to ignite by spark discharge instead of this piezoelectric device, in this case ignition Switch on the spark circuit in position or slightly earlier.

In addition, in the above-described embodiment, the gas burner A is composed of a fire ignition gas burner A, which is replaced with a pilot burner which only ignites at the time of ignition, or is removed directly to the main gas burner. It can also be configured in a manner of ignition. In the drawing, the cover body 6 was formed by two upper and lower pieces on the work piece, and the projecting piece 11 was protruded from the upper cover body 6a, and the bent piece 21 was provided on the lower cover body 6b. You may comprise a board of hawks.

Moreover, in the example shown in the figure, the pin 29 which engages with the notch 17a provided in the said stopper funn 17 is installed in the operation shaft 5 so that children may not operate an operation shaft 5 without permission. When the operation shaft 5 is pressed, the pin 29 is peeled off from the notch 17a so that the operation shaft 5 can be rotated.

In this way, according to the present invention, at least a weak fire position is provided at the operation position of the operation shaft, the engagement piece protrudes from the connecting body, and a gap larger than the thickness of the engagement piece from the cover plate. When the operation shaft is rotated by a simple configuration in which the interlocking piece is brought into contact with the engaging piece at the ignition position, and the operating shaft is operated to convert it to a weak position, the stopper portion on which the protruding piece abuts is installed on the cam surface. At the same time, there is an effect that a gas cock device capable of accurately stopping at an ignition position and a weak fire position which requires a reliable stop at the same time as a large angle of rotation is obtained.
