Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a flashing operation device that is effective when applied to various gas combustion appliances such as gas stoves, gas ovens, and gas ranges.

[Conventional technology]

BACKGROUND ART Conventionally, the blinking control device for various gas combustion appliances such as gas stoves, gas ovens, and gas ranges has generally been a so-called push-turn type or turn-turn type to turn the ignition switch ON and OFF and to open and close the gas cooker.

[The problem that the idea attempts to solve]

However, in the case of the conventional push-turn type or turn-turn type, the operation is complicated because the ignition switch must be turned on by a push operation and the lock turned open and closed by a turn operation. The rotary type has the disadvantage that the ignition switch is turned on by moving in the radial direction with the rotation of the cam, and the ignition switch is turned off after the ignition is completed.
It is difficult to do so.

A rotary lever type is also known, but the gas kettle opens almost simultaneously with the ignition operation and the ignition switch turns on.When the kottok is fully open, the switch turns on.
Since the spark discharge ends when it is turned off, the spark discharge period is short, resulting in a low ignition rate and the disadvantage that raw gas is likely to come out.

Therefore, this idea eliminates the push operation and simply rotates the ignition switch to operate the flashing functions such as turning the ignition switch on and off to opening and closing the gas tank, safely, easily, and reliably. To provide a simplified flashing operation device for gas combustion appliances that is highly reliable.

[Means to solve the problem]

This invention operates an ignition switch S at the tip of an ignition lever 3 that rotates a cock V, which is biased in the return direction (counterclockwise in the figure) by a torsion spring 2 on a support shaft 1 that is mounted on a frame A. A diagonal convex cam 4 is provided for advancing and retracting the switch plate 6, and the switch plate 6 is rotatable together with the ignition lever 3 on the same support shaft 1 by a spring 5, and one end of the ignition lever 3 (in the return direction and the opposite direction) is provided. The switch plate 6 is connected to the diagonal convex cam 4 of the ignition lever 3 so that it can move forward and backward in the axial direction by engaging and disengaging the slanted convex cam 4 of the ignition lever 3. The tip engaging portion 9 of the rotary lever 8 into which the connecting pin 12 is fitted and engaged is engaged with the engaging recess 10 formed in the ignition lever 3 with a certain play gap a, and is rotatable together. By rotating the ignition lever 3 at a certain angle with respect to the switch plate 6, the convex cam 4 acts to hold the switch plate 6 in a lifted position that activates the ignition switch, and the ignition lever 3 is rotated relative to the rotating plate 1.
1 or the engaging portion 9, the rotary plate 11 or the engaging portion 9 is provided so as to be rotatable at a fixed angle together with the switch plate 6, and the rotating plate 11 or the engaging portion 9 is provided so as to be switchable to the open position of the ignition lever 3. When the rotational force is released, the ignition lever 3 is rotated in the return direction relative to the switch plate 6 by the action of the spring, the convex cam 4 is removed, and the switch plate 6 is returned to the retracted position, and the ignition lever 3 is brought into contact with the rotary plate 11 or the engaging portion 9. Technical means provided so that it can be held in the combustion position, and when extinguishing the fire, the ignition lever 3 is moved to the initial position by cooperating with the switch plate 6 at a certain angle to switch the rotary plate 11 or the engaging part 9 to the closed position of the pot V. The above problem is solved by adopting the following.

[Effect]

Since this device has the above configuration, when the ignition lever 3 is rotated by a certain angle during initial operation (the position where the ignition switch turns ON), the switch plate 6
Connecting pin 12 of Kotoku V (or connecting pin 12
The ignition lever 3 comes into contact with the tip engaging portion 9) of the rotary lever 8 that engages with the switch plate 6, and its rotation is prevented.As the ignition lever 3 rotates with respect to the switch plate 6, the slanted convex cam 4 engages the switch plate 6. Move the tip in the axial direction, lift it to the side using the support shaft 1 as a fulcrum, push the operating rod 13 of the ignition switch S with the switch plate 6, turn on the ignition switch S, and turn on the igniter (Fig. (not shown) to emit sparks from the spark plug. Then, when the ignition lever 3 is further rotated to a certain angle (the position where the main burner is ignited)
The ignition lever 3 and the switch plate 6 move together by the elastic force of the spring 5, and while the ignition switch S is kept in the ON position (the tip of the switch plate 6 rests on the diagonal convex cam 4). ) Engagement recess 1 of ignition lever 3
The connecting pin or the tip engaging portion 9 of the rotary lever 8 engages with the lower edge 10a of the rotary lever 8 to rotate the rotary lever 8 about the support shaft 7, and the connecting pin 12 is rotated directly or via the rotary plate 11. Turn V to open the gas passage 14, supply gas to the burner, and ignite it with the spark from the ignition plug. after that,
When the rotation operation of the ignition lever 3 is released, the ignition lever 3 is reversed by a certain angle by the torsion spring 2 (until the upper edge 10b of the engagement recess 10 is engaged with the tip engagement part 9 of the rotary lever 8). Rotate back and
The switch plate 6 is removed from the diagonal convex cam 4, and the ignition switch S is turned off to stop the igniter and hold it in the combustion position. Next, when extinguishing the burner, the ignition lever 3 is rotated in the reverse direction to the initial position, and the ignition lever 3 and the switch plate 6 rotate as one, and the upper edge 10b of the engagement recess 10 of the ignition lever 3 rotates. Push down the connecting pin 12 or the end engagement part 9 of the rotary lever 8, rotate the pot V directly or via the rotary lever 8 about the support shaft 7, close the gas passage 14, and stop the gas from flowing to the burner. It cuts off the supply.

〔Example〕

Hereinafter, one embodiment of the flashing operation device for a gas combustion appliance according to this invention will be described in detail with reference to the drawings.

In the drawing, reference numeral 1 denotes a support shaft mounted on the frame A, and one end of the ignition lever 3 is pivoted to the support shaft 1 so that it can be rotated by being biased in the return direction (counterclockwise direction in the drawing) by a torsion spring 2. At the tip of the ignition lever 3, two oblique convex cams 4 having a high step portion 4a and a low step portion 4b are provided with an engagement recess 10. The reason why the two slanted convex cams 4 are provided is to prevent the switch plate 6, which will be described later, from tilting when it is lifted laterally. Reference numeral 3a denotes a stopper piece provided on the tip side of the ignition lever 3, which allows both the ignition lever and the switch plate to rotate after coming into contact with the upper part of the switch plate 6 when the ignition lever is released. Reference numeral 6 denotes a switch plate, which is connected to the ignition lever 3 and the support shaft 1 by a torsion spring 5 with a collar 15 having an inner diameter larger than the outer diameter of the support shaft 1 interposed between the ignition lever 3 and the switch plate 6. The elastic force of the spring 5 urges the ignition lever 3 in the rotational direction opposite to the return direction so that the ignition lever 3 can move together, and its rotation is restricted, and the torsion spring 5 also acts as a compression spring. The ignition lever 3 is pivoted so that its movement in the axial direction is restricted, and the proximal ends of the cut and raised pieces 6b, 6b provided near the center near the tip of the ignition lever 3 engage and disengage from the diagonal convex cam 4 of the ignition lever 3. , the operating rod 13 of the ignition switch S is brought into contact with the tip 6a, and the proximal end of the cut and raised piece 6b of the switch plate 6 is connected to the high step 4a of the oblique convex cam 4 of the ignition lever 3. , low section 4b
The tip 6a of the switch plate 6 by engaging and disengaging with the
As the support shaft 1 moves in and out of the axial direction, the switch plate 6 assumes an inclined position, compresses the torsion spring 5 and puts it in a free state, and the tip 6a comes into contact with and separates from the operating rod 13, turning the ignition switch S on and off. I'm trying to get it done. Further, reference numeral 8 denotes a rotary lever provided in a direction perpendicular to the ignition lever 3, one end of which is pivotally mounted on a fixed support plate 16 by a support shaft 7, and its tip engaging portion 9 is connected to the ignition lever. penetrates into the engagement recess 10 of No. 3 with a certain play gap a, and
The cut and raised pieces 6b, 6b of the switch plate 6 are extended so as to be engaged with each other, and when the ignition lever 3 is rotated, the lower edge 10a or the upper edge 10b of the engagement recess 10 engages with the tip of the rotary lever 8. A certain play gap a at the joint 9
The rotary lever 8 can be rotated by the ignition lever 3. V is a gas tank installed in the gas passage 14 of the valve housing B, and its valve shaft 17 is made to protrude from the valve housing B, and the protruding portion is connected to the rotating plate 1.
1, and a connecting pin 12 fixed to one side end of the rotary plate 11 is loosely inserted into the elongated hole 9a formed in the rotary lever 8, and the rotary lever 8 is connected to the gas cylinder V, the connecting pin 12, and the rotary plate 11. be connected via
A gas tank V is rotated by a rotating lever 8 rotated by an ignition lever 3, so that a gas passage 14 can be opened and closed. Further, 20 is a spring seat of the gasket V, 21 is a pressing spring for maintaining the anastomotic state of the gaskock V, and 22 is a switch mounting plate, which is fixed to the frame A.

In the above structure, the operation will be explained in detail. When the ignition lever 3 is rotated by a certain angle in the clockwise direction in FIG. Since the cut-and-raised piece 6b comes into contact with the tip engaging portion 9 of the rotary lever 8 and its rotation is prevented by the frictional resistance of the gas cock V, the ignition lever 3 precedes the switch plate 6 and closes in its engaging recess. 10 play clearance a
The proximal end of the cut and raised piece 6b of the switch plate 6 rises from the low step part 4b of the oblique convex cam 4 to the high step 4a, and the tip end 6a of the switch plate 6 is attached to the support shaft 1.
The switch plate 6 is lifted to the side against the torsion spring 5 as a fulcrum, and the switch plate 6 is placed in an inclined position. Turn on,
The igniter (not shown) is activated to emit a spark from the ignition plug to ignite the burner. At this time, the engagement recess 10 of the ignition lever 3
The lower edge 10a of the rotary lever 8 contacts the tip engaging portion 9, and the ignition lever 3 and the switch plate 6 rotate together as one unit by the elastic force of the torsion spring 5 (from the state shown in Fig. 1). (See the state in Figure 4). continue,
When the ignition lever 3 is rotated clockwise by the operating handle 18 to a certain angle, that is, to the lower limit position, the ignition lever 3 and the switch plate 6 rotate as one, and while the ignition switch S is kept on, That is, the high step portion 4a of the oblique convex cam 4 of the ignition lever 3
The lower edge 10 of the engagement recess 10 of the ignition lever 3 remains on the base end of the cut and raised piece 6b of the switch plate 6.
Lift the end engaging portion 9 of the rotary lever 8 with a to rotate the rotary lever 8 in the clockwise direction shown (FIG. 2) with the support shaft 7 as a fulcrum, and rotate the rotary plate 11 in the same direction via the connecting pin 12. Then, the valve stem 1 is removed from the rotating plate 11.
7 to fully open the gas tank V, gas is supplied from the gas passage 14 to the burner, and the previous spark ignites it (see the state shown in FIG. 4 to the state shown in FIG. 5). After that, turn the ignition lever 3
When the rotation operation by the operation handle 18 is released, the rotation of the ignition lever 3 by the torsion spring 2 in the counterclockwise direction shown in the figure is caused by the torsion spring 5 of the switch plate 6.
The ignition lever 3 overcomes the rotational biasing force and rapidly rotates back against the switch plate 6, causing the cut and raised piece 6b of the switch plate 6 to move from the high step 4a of the oblique convex cam 4 at the tip of the ignition lever 3. Since the base end of the switch plate 6 is removed, the tip end 6a of the switch plate 6 returns to its original retracted position, changes from an inclined position to a parallel position, and releases the push and movement of the operating rod 13 of the ignition switch S by the switch plate 6. The ignition switch S is turned OFF to stop the spark from the ignition plug caused by the activation of the igniter (see the state shown in FIG. 5 to the state shown in FIG. 6). After the stopper piece 3a of the ignition lever 3 contacts the switch plate 6, the stopper piece 3a of the ignition lever 3 rotates slightly with the switch plate 6, and the ignition lever 3
The upper edge 10b of the engagement recess 10 returns a certain angle until it comes into contact with the tip engagement part 9 of the rotary lever 8 and then stops, and the burner continues to burn at this position (see FIG. 6).

Next, when extinguishing a fire, when the ignition lever 3 in the state shown in Fig. 6 is rotated counterclockwise as shown in the figure by its operation handle 18 to the initial position (see Fig. 1), the ignition lever 3 and the switch plate 6 are torsioned. Together with the biasing torque of the spring 5, they rotate together, and the upper edge 10b of the engagement recess 10 of the ignition lever 3 pushes down the tip engagement portion 9 of the rotary lever 8, causing the rotary lever 8 to rotate as shown in the figure. Fig. 2) Rotates counterclockwise around the support shaft 7, rotates the rotating plate 11 in the same direction via the connecting pin 12, and rotates the gas tank V via the rotating plate 11 and the valve shaft 17. The burner is completely closed and the gas supply to the burner is cut off to extinguish the burner (see Figure 1). In this embodiment, the rotating plate 11
The tip engaging portion 9 of the rotary lever 8 that engages with the connecting pin 12 fixed to the
Although the rotating plate 11 may be inserted directly into the engagement recess 10 of the ignition lever 3, the Kotoku V may be installed so that the valve shaft 17 of the Kotoku V is parallel to the support shaft 1. Alternatively, the so-called lever operating method in which the ignition lever 3 is pushed down or pulled up may be used as an example, but the ignition lever 3 may be fitted into the support shaft 1 and the support shaft 1 The ignition lever 3 may be rotated as an operating shaft. Furthermore, the switch plate 6 has been shown to have a configuration in which the tip end 6a thereof moves back and forth in the axial direction to operate the operating rod 13 in an inclined position.
The engaging parts such as the oblique convex cam 4 of the ignition lever 3 and the cut-and-raised part 6b of the switch plate 6 are aligned at 120° to 180° on the circumference.
By expanding the switch plate 6 to the angular position, the switch plate 6 can be moved forward and backward at right angles to the support shaft 1 in a parallel position.

[Effect of idea]

As explained above, this idea is based on the initial operation at the time of ignition, which turns on the ignition switch in advance, blows out the spark from the ignition plug, and then opens the gas tank to supply gas to the burner. Since the structure is such that the ignition spark is completely stopped by turning off the ignition switch, there is no danger of raw gas being released due to malfunction, which is desirable from a safety standpoint. In addition, the mechanism is simple because the ignition lever engages with the valve stem of the Kotoku with a certain play gap, and spark discharge ignition can be performed even when the Kotuku is closed, making the ignition operation extremely light and rapid. ignition error lever (operating shaft)
If you let go of your hand, the ignition switch will quickly turn off.
consumption of power batteries, etc. is minimized, and
Since the operation is only a rotational operation, the safety is significantly improved since erroneous operation can be avoided, and the cost can be reduced.
