Description
Technical Field
The present invention relates to a gas cock operated by an operation knob exposed to a top plate of a stove.
Background
As such a gas cock, a gas cock having: an operation shaft which is long in the vertical direction, and an operation knob which is exposed on a top plate of the stove is arranged at the upper end of the operation shaft; a plug in the cock body, which is rotated by the rotation of the operation shaft to adjust the gas supply amount to the burner; an electromagnetic safety valve in the cock body, the electromagnetic safety valve having a valve seat, a valve body, a valve spring that biases the valve body in a closing direction in which the valve body approaches the valve seat, an adsorption piece that is coupled to the valve body via a valve shaft that extends in an opening direction away from the valve seat, and an electromagnet that faces the adsorption piece, the electromagnetic safety valve being disposed in a horizontal posture in which an opening/closing direction of the valve body is horizontal; a push rod moving downward against the spring in linkage with the operation shaft being pressed; and a cam member in the plug body, which has a pressure receiving arm portion opposed to a lower end of the push rod and a pressure arm portion opposed to the valve body of the electromagnetic safety valve, and which is rotated about a horizontal axis orthogonal to an opening/closing direction of the valve body of the electromagnetic safety valve by a torque input via the pressure receiving arm portion in accordance with a downward movement of the push rod, and which pushes the valve body of the electromagnetic safety valve to a valve-open position where the suction piece abuts against the electromagnet via the pressure arm portion (for example, see patent document 1).
In addition, in such a gas cock, it is also conceivable to provide a structure including: a switch operating panel which is pressed by the operating shaft to move downwards by the pressing operation of the operating shaft; and a microswitch that is turned on by a downward movement of the switch operation plate, wherein a push rod is disposed at a portion located on the opposite side of the microswitch with respect to the operation shaft in a plan view, a rod pressing portion facing an upper end of the push rod is provided on the switch operation plate, and the push rod is pressed by the rod pressing portion to move downward by moving the switch operation plate downward by pressing the operation shaft.
However, in this configuration, when the switch operating plate is moved downward by the pressing operation of the operating shaft, the switch operating plate is inclined in such a manner that the lever pressing portion side is raised due to the upward-facing spring force acting on the push rod. Further, even if the switch operating plate is moved downward to a position at which the microswitch is turned on, the push rod is not pushed downward to a proper position because the switch operating plate is inclined, and the valve body of the electromagnetic safety valve cannot be pushed to the valve-open position because of insufficient rotation of the cam member. Therefore, in order to push the valve body of the electromagnetic safety valve to the valve opening position, it is necessary to press the operating shaft continuously after the microswitch is turned on, so that the switch operating plate is tilted to eliminate the inclination of the lever pressing portion side, with the abutting portion of the microswitch abutting on the switch operating plate as a fulcrum, and the push rod is pressed in place. As a result, when the switch operation plate is tilted with the contact portion of the micro switch in contact with the switch operation plate as a fulcrum, an excessive pressing force acts on the micro switch, thereby adversely affecting the durability of the micro switch.

Disclosure of Invention
In view of the above problems, an object of the present invention is to provide a gas cock capable of preventing an excessive pressing force from acting on a microswitch to adversely affect the durability thereof.
In order to solve the above problem, the present invention provides a gas cock including: an operating shaft with the length direction in the vertical direction, and an operating knob exposed out of the top plate of the stove is arranged at the upper end of the operating shaft; a plug in the cock body, which is rotated by the rotation of the operation shaft to adjust the gas supply amount to the burner; an electromagnetic safety valve in the cock body, the electromagnetic safety valve having a valve seat, a valve body, a valve spring that biases the valve body in a closing direction in which the valve body approaches the valve seat, an adsorption piece that is connected to the valve body via a valve shaft, and an electromagnet that faces the adsorption piece, the valve shaft extending in an opening direction in which the valve shaft is separated from the valve seat, the electromagnetic safety valve in the cock body being disposed in a horizontal posture in which an opening and closing direction of the valve body is horizontal; a push rod moving downward against the spring in linkage with the operation shaft being pressed; and a cam member in the cock body, the cam member having a pressure receiving arm portion opposed to a lower end of the push rod and a pressing arm portion opposed to the valve body of the electromagnetic relief valve, the cam member being rotated about a horizontal axis orthogonal to an opening and closing direction of the valve body of the electromagnetic relief valve by a torque input via the pressure receiving arm portion in accordance with a downward movement of the push rod, and the valve body of the electromagnetic relief valve being pushed to a valve-open position where the adsorption piece is brought into contact with the electromagnet by the pressing arm portion, the gas cock including: a switch operation plate which is pressed by the operation shaft to move downwards through pressing the operation shaft; and a microswitch that is turned on by a downward movement of the switch operation plate, wherein a push rod is disposed at a portion located on the opposite side of the microswitch with respect to an operation shaft in a plan view, a rod pressing portion facing an upper end of the push rod is provided on the switch operation plate, and the switch operation plate is moved downward by the operation shaft being pressed, whereby the push rod is pressed by the rod pressing portion and moved downward.
According to the present invention, when the operation shaft is pressed down to move the switch operation plate downward to a position where the microswitch is turned on, the switch operation plate abuts against the stopper portion, and as the operation shaft is further pressed down, the switch operation plate is tilted up with the stopper portion as a fulcrum to eliminate the inclination of the lever pressing portion side which is raised, so that the push rod is pressed downward to a position, the cam member is sufficiently rotated, and the valve body of the electromagnetic safety valve is reliably pushed to the valve opening position. Further, since the stopper portion is a fulcrum when the switch operation plate is tilted up, an excessive pressing force does not act on the microswitch, and adverse effects on the durability of the microswitch can be prevented.
In the present invention, it is preferable that: the stopper is provided on an extension line of a connecting line connecting the operating shaft and the push rod when viewed from above. According to the present invention, the tilting torque about the stopper portion as a fulcrum in association with the pressing of the operating shaft and the spring force urging the push rod upward act on the switch operating plate along the same vertical plane including the connecting line. Therefore, the switch operation panel is not twisted, and the push rod can be reliably pushed downward to a proper position.
Further, in the present invention, it is preferable that: a projection part projecting upward from the upper surface of the limit part is provided, and a positioning hole through which the projection part penetrates is formed on the switch operating plate. According to the present invention, the switch operating plate is rotationally displaced about the operating shaft without abutting against a portion other than the stopper portion of the cock body, and it is possible to prevent an increase in the pressing operating force of the operating shaft due to resistance from the abutting portion.
In the present invention, it is preferable that: the pressure receiving surface of the pressure receiving arm portion of the cam member, which is abutted by the lower end of the push rod, is formed as an arc surface (R surface) centered on an axis parallel to the rotation axis of the cam member. According to the present invention, the sliding resistance of the lower end of the push rod against the pressure receiving surface can be reduced. As a result, the pressing force of the operating shaft can be reduced, and further, the generation of abrasion powder due to the sliding of the lower end of the push rod with respect to the pressure receiving surface can be suppressed, thereby improving the durability.

The oven shown in fig. 1 is a built-in oven having an oven main body C provided to be built in a countertop, not shown, of a system kitchen. The oven includes a pair of left and right oven burners B, B, in which the pair of left and right oven burners B, B are exposed on an oven top plate TP, and the oven top plate TP is placed on the table top so as to cover the upper surface of the oven main body C. A gas cock 1 according to the embodiment of the present invention shown in fig. 2 to 6 is inserted into the gas supply path for each burner B.
The gas cock 1 includes: an electromagnetic relief valve 3 (see fig. 3) provided on the upstream side and a plug 4 (see fig. 4 and 5) provided on the downstream side in the plug body 2. The cock body 2 is formed with: a gas inflow port 21 located on the upstream side of the electromagnetic relief valve 3; and a gas outflow opening, not shown, located on the downstream side of the plug 4. The gas cock 1 further includes an operation shaft 5 having a longitudinal direction in the vertical direction, and an operation knob 51 (see fig. 1) exposed to the stove top plate TP is attached to an upper end of the operation shaft 5.
Referring to fig. 4, the operating shaft 5 is rotatably and vertically movably supported through a shaft hole 221 and a shaft hole 231, wherein the shaft hole 221 is formed in the fixed plate 22 fastened to the upper end of the plug body 2, the shaft hole 231 is formed in the support plate 23, and the support plate 23 is integrally fastened to the fixed plate 22. An engaging portion 52 is provided at the lower end of the operating shaft 5 in a protruding manner, and the engaging portion 52 is engaged with a notch portion 41 formed at the upper end of the plug 4 in a vertically slidable manner. Therefore, the plug 4 is rotated by the engagement portion 52 by the rotation of the operation shaft 5, and the amount of the supplied gas supplied to the burner B is adjusted.
A flange portion 53 is provided above the engaging portion 52 of the operating shaft 5, and the flange portion 53 abuts on an upper surface of a switch operating plate 56 described later. The operating shaft 5 is biased upward by a spring 54 interposed between the switch operating plate 56 and the plug 4 via the switch operating plate 56 and the flange portion 53. The operation shaft 5 is provided with protrusions 55 protruding radially outward from 1 portion around the flange portion 53. The 1 st rotation stopper 24 cooperating with the protrusion 55 is provided on the upper inner surface of the portion of the cock body 2 receiving the plug 412 nd rotation stop portion 242And the 3 rd rotation stop portion 243The 1 st rotation stopper 2412 nd rotation stop portion 242And the 3 rd rotation stop portion 243Are arranged separately in the circumferential direction. Further, the fixing plate 22 is formed with a rotation stop hole 222, and the rotation stop hole 222 is used for the projection 55 to abut against the 1 st rotation stop portion 24 when the operation shaft 5 is positioned1The projection 55 is engaged from below in the key-off position of (2). Then, in a state where the projection 55 is disengaged downward of the rotation stop hole 222 by pressing the operation shaft 5 at the key-off position, the operation shaft 5 is rotated until the projection 55 abuts on the 2 nd rotation stop portion 242When the amount of the supplied gas to the burner B is the maximum at the ignition position of (3), and then when the operation shaft 5 is moved upward by canceling the pressing at the ignition position, the projection 55 goes over the 2 nd rotation stop portion 242When the operating shaft 5 is rotated in this state until the projection 55 abuts on the 3 rd rotation stop portion 243The amount of the supplied gas to the furnace burner B is the smallest at the weak fire position of (3).
As shown in fig. 3, the electromagnetic safety valve 3 includes: a valve seat 32 formed at one end of the valve chamber 31 in the cock body 2 communicating with the gas inlet 21; a valve body 33 in the valve chamber 31, which faces the valve seat 32; a valve spring 34 that biases the valve body 33 in a closing direction to approach the valve seat 32; an adsorption sheet 35 connected to the valve body 33 via a valve shaft 33a extending in an opening direction away from the valve seat 32; and an electromagnet 36 opposed to the adsorption sheet 35. Then, the valve body 33 is sucked and held at the valve-open position by energizing the electromagnet 36 in a state where the valve body 33 is pushed to the valve-open position where the suction piece 35 abuts against the electromagnet 36.
Here, the electromagnetic relief valve 3 is disposed in a horizontal posture in which the opening/closing direction of the valve body 33 is the horizontal direction. As shown in fig. 6, components of an operating mechanism that pushes the valve body 33 of the electromagnetic safety valve 3 to the valve-open position in conjunction with the operation shaft 5 being pushed down are provided with: a push rod 6, the push rod 6 moving downward against a spring 61; and a cam member 7 in the plug body 2, which has a pressure receiving arm portion 71 facing the lower end of the push rod 6 and a pressing arm portion 72 facing the valve body 33 of the electromagnetic relief valve 3. The cam member 7 is rotated about a horizontal axis orthogonal to the opening/closing direction of the valve body 33 of the electromagnetic relief valve 3, that is, about a horizontal support shaft 73 by a torque input through the pressure receiving arm 71 in accordance with the downward movement of the push rod 6, and pushes the valve body 3 of the electromagnetic relief valve 3 to the valve-open position by the pressure arm 72.
The pressure receiving surface 71a of the pressure receiving arm portion 71, which is abutted by the lower end of the push rod 6, is formed as an arc surface (R surface) centered on an axis parallel to the rotation axis of the cam member 7. This reduces the sliding resistance of the lower end of the push rod 6 against the pressure receiving surface 71 a. As a result, the pressing force of the operating shaft 5 can be reduced, and the generation of abrasion powder due to the sliding of the lower end of the push rod 6 with respect to the pressure receiving surface 71a can be suppressed, thereby improving the durability.
The gas cock 1 of the present embodiment further includes: a switch operation plate 56 that is pushed by the operation shaft 5 (specifically, the flange portion 53) and moves downward when the operation shaft 5 is pushed; a 1 st micro switch 8 mounted on an outer surface of the cock body 2 so as to be turned on by a downward movement of the switch operating plate 56; and a 2 nd micro switch 9 interposed between the fixed plate 22 and the support plate 23 and cooperating with a cam 57 rotating together with the operation shaft 5. Referring to fig. 4, a recess 571 that is recessed radially inward is formed at 1 circumferential location of the cam 57. When the operating shaft 5 is rotated from the key-off position, the operating lever 91 of the 2 nd microswitch 9 is pressed to a portion of the cam 57 other than the recess 571, and the 2 nd microswitch 9 is turned on. When the 1 st microswitch 8 is turned on, electricity is supplied to an igniter outside the figure to generate a spark at an ignition electrode attached to the stove burner B; when the 2 nd micro switch 9 is turned on, the electromagnet 36 of the electromagnetic safety valve 3 is energized, and when the inflammation detection element Ba such as a thermocouple attached to the stove burner B does not detect inflammation after a predetermined time has elapsed from the start of energization, the energization of the electromagnet 36 is stopped, and the electromagnetic safety valve 3 is closed.
Referring also to fig. 5, flange portion 53 of operating shaft 5 is formed in a stepped shape having an upper large diameter portion and a lower small diameter portion. The switch operation plate 56 is provided with: a through hole 561 at the center portion for fitting the small diameter portion of the flange portion 53; and a switch pressing portion 562 that extends from the center portion toward the arrangement portion side of the 1 st microswitch 8 and abuts against the operating rod 81 of the 1 st microswitch 8 from above.
The push rod 6 is disposed at a portion opposite to the 1 st microswitch 8 with the operation shaft 5 therebetween in a plan view. Further, the switch operating plate 56 is provided with a lever pressing portion 563 which extends from the central portion to the arrangement portion side of the push rod 6, faces the upper end of the push rod 6, and by pressing the operating shaft 5, the switch operating plate 56 is moved downward, and thereby the push rod 6 is pressed by the lever pressing portion 563 to be moved downward.
It should be noted that, when the switch operating plate 56 is moved downward by the operating shaft 5 being pressed, the switch operating plate 56 is caused to tilt in such a manner that the lever pressing portion 563 side is raised due to the urging force of the upward spring 61 acting on the push rod 6. Even if the switch operating plate 56 is lowered to the position where the 1 st microswitch 8 is turned on, the push rod 6 is not pushed down to a proper position because the switch operating plate 56 is inclined, and the valve element 33 of the electromagnetic safety valve 3 cannot be pushed to the valve-open position because of insufficient rotation of the cam member 7. Therefore, in the case where the later-described stopper portion 25 is not provided, in order to push the valve body 33 of the electromagnetic safety valve 3 to the valve-open position, it is necessary to press the operating shaft 5 continuously after the 1 st micro switch 8 is turned on, to tilt the switch operating plate 56 about the contact portion of the operating rod 81 of the 1 st micro switch 8 with the switch pressing portion 562 as a fulcrum, to eliminate the inclination of the rod pressing portion 563 side from rising, and to press the push rod 6 to a proper position. As a result, when the switch operating plate 56 is lifted up with the contact portion as a fulcrum, an excessive pressing force acts on the 1 st micro switch 8, and the durability of the 1 st micro switch 8 is adversely affected.
Therefore, in the present embodiment, the stopper portion 25 is provided in the portion of the plug body 2 located between the operation shaft 5 and the 1 st micro-switch 8 in a plan view, and when the switch operation plate 56 moves downward to a position where the 1 st micro-switch 8 is turned on, the switch operation plate 56 abuts against the stopper portion 25. According to the present embodiment, as the switch operating plate 56 is moved downward to the position where the 1 st micro switch 8 is turned on and then the operating shaft 5 is continuously pushed down, the switch operating plate 56 is tilted up with the stopper portion 25 as a fulcrum, the inclination of the lever pressing portion 563 is eliminated, the push rod 6 is pushed down to a proper position, the cam member 7 is rotated sufficiently, and the valve body 33 of the electromagnetic relief valve 3 is reliably pushed to the valve opening position. Further, since the stopper portion 25 is a fulcrum when the switch operating plate 56 is lifted, an excessive pressing force does not act on the 1 st micro-switch 8, and adverse influence on the durability of the 1 st micro-switch 8 can be prevented.
In the present embodiment, the stopper portion 25 is provided on an extension of a connection line connecting the operation shaft 5 and the push rod 6 in a plan view. Accordingly, the tilting moment about the stopper portion 25 as a fulcrum with the operation shaft 5 being pressed and the biasing force of the spring 61 biasing the push rod 6 upward act on the switch operation plate 56 along the same vertical plane including the connection line. Therefore, the switch operating plate 56 is not twisted, and the push rod 6 can be reliably pushed downward to a proper position.
Further, in the present embodiment, the projection 251 is provided so as to project upward from the upper surface of the stopper 25, and the switch operating plate 56 is provided with the positioning hole 564 through which the projection 251 penetrates. Thus, the switch operating plate 56 is rotationally displaced around the operating shaft 5, and does not abut against the portion of the plug body 2 other than the stopper portion 25. Therefore, it is possible to prevent the pressing operation force of the operation shaft 5 from increasing due to the resistance from the abutting portion other than the stopper portion 25.
The embodiments of the present invention have been described above with reference to the drawings, but the present invention is not limited thereto. For example, in the above embodiment, the 2 nd micro switch 9 is provided in addition to the 1 st micro switch 8, but the 2 nd micro switch 9 may be omitted, and when the 1 st micro switch 8 is turned on, the energization of the igniter and the energization of the electromagnet 36 of the electromagnetic relief valve 3 may be started.
