Description

The present invention relates to a gas stove, and more particularly to a gas stove having a function of preventing inadvertent ignition.

There are two gas stoves on the left and right of the front side (the side closer to the user) of the top plate that covers the upper part of the gas stove body, as two front side stove burners, and in the center of the rear side of the top plate as a rear side stove burner. While one stove burner in total of three is arranged, there is one equipped with a grill burner in the grill storage arranged in the central part in the left-right direction of the gas stove main body.

As such a gas stove, for example, as shown in Patent Document 1, four point fire extinguishing buttons for extinguishing each of the three stove burners and the grill burner are sandwiched between a grill door for opening and closing the front opening of the grill storage. Then, there are two on each side, that is, one pair. Each point fire extinguishing button has a front end side portion protruding toward the front side of the gas stove main body, and this protruding front end side portion can be pushed and operated as an operation portion.

In this gas stove, a pair of point fire extinguishing buttons on the left and right sides of the grill door are arranged adjacent to each other along the left and right direction (width direction) of the gas stove body, and between the two adjacent point fire extinguishing buttons. An intermediate member having the same shape as the front end side portion of the point fire extinguishing button and projecting to the front side is arranged like the point fire extinguishing button. This intermediate member cannot move in the same direction as the operation direction of the point fire extinguishing button, and cannot be pushed and operated like the point fire extinguishing button.

Hereinafter, the gas stove according to the embodiment of the present invention will be described with reference to the attached drawings. As a gas stove according to an embodiment of the present invention, a built-in type gas stove 1 including a stove portion and a grill will be described with reference to the accompanying drawings.

As shown in FIG. 1, the top plate 2 constituting the top surface portion of the gas stove 1 is provided with three stove portions 3. Each stove unit 3 is provided with a stove burner 4 having a different thermal power, a discharge type ignition device 5 and an ignition detection device 6, and further, on the upper surface of the top plate 2, the trivet corresponding to the stove unit 3 is provided. 7 is placed. In this example, the left and right stove burners 4 on the front side (closer to the user) of the top plate 2 are high heat burners 4, and the central stove burner 4 on the rear side is a small heat burner.

The gas stove 1 is provided with a grill 8. The grill 8 includes a grill storage formed in the central portion of the main body of the gas stove 1, a grill burner (not shown) provided in the grill storage, and an ignition device and an ignition detection device (not shown). The front end of the grill 8 is open to the front surface of the gas stove 1 and is closed by the grill door 9 so as to be openable and closable.

As the ignition device 5, a well-known structure is adopted in which a high-pressure pulse generated by an igniter causes a spark plug provided at a fuel gas discharge port in a stove burner and a grill burner to discharge and ignite. Further, the ignition detection device 6 has a well-known structure that detects the ignition state by using a thermocouple in which a thermoelectromotive force is generated by the heat of the flame.

A front panel 11 is provided on the front surface of the gas stove 1. Two point fire extinguishing buttons (point fire extinguishing operation tools) 12 for igniting and extinguishing the front left side stove burner 4 and the rear center side stove burner 4 are provided side by side on the upper left side of the front panel 11. At the upper right side of the front panel 11, two point fire extinguishing buttons 12 for igniting and extinguishing the stove burner 4 and the grill burner on the front right side are provided side by side.

Further, above each point fire extinguishing button 12, a thermal power adjusting lever 13 is arranged so as to be movable left and right in order to adjust the amount of gas supplied to each burner to adjust the thermal power.

A battery case 14 for accommodating a battery as a power source for a built-in control unit and the like is provided in the lower part on the left side of the front panel 11.

On the back of each point fire extinguishing button 12, a gas valve block 15 having the same specifications for supplying gas to the stove burner 4 of the gas stove 1 or the grill burner is provided. FIG. 5 shows a side view of the gas valve block 15 and its operating portion, and FIG. 8 shows a supply route diagram of fuel gas in the gas valve block 15.

As shown in these figures, the gas valve block 15 includes a solenoid opening / closing type safety valve 16, a main valve 17, first and second latch type solenoid valves 18a and 18b used for switching between large heat and small heat, and , A flow rate adjusting valve 19 for adjusting thermal power is incorporated. In the gas valve block 15, the fuel gas flowing in from the gas inflow port 20 passes through the safety valve 16, the main valve 17, the first and second latch type solenoid valves 18a and 18b, and the flow rate adjusting valve 19, and the gas outflow port 21. It is sent from and supplied to the stove burner 4 (or the grill burner).

The safety valve 16 is maintained in an open state by a control unit (not shown) only when a flame is detected by the ignition detection device 6, and when the flame is no longer detected, the maintenance of the open state by the control unit is stopped. It will be closed. As a result, the outflow of fuel gas is prevented when the ignition detection device 6 does not detect the flame due to spillage or extinction due to the wind.

As shown in FIG. 5, a support case 24 is connected and fixed to the front portion of the gas valve block 15. The support case 24 is equipped with a slider 25 that operates in conjunction with the point fire extinguishing button 12 so as to be slidable in the front-rear direction, and is incorporated by sliding the support case forward with a spring 26. The front end of the valve rod 17a of the main valve 17 is butt-opposed to the rear end of the slider 25. As the slider 25 moves backward, the valve rod 17a is brought into contact with the rear end of the slider 25 and is pressed and displaced rearward against the spring-forced force to open the main valve 17. On the contrary, as the slider 25 in the rear position moves forward, the valve rod 17a moves forward following the displacement of the slider 25, and the slider 25 moves forward beyond a certain position, so that the valve rod 17a is in an open state. The main valve 17 of the above is urged and pressed against the valve seat so as to be closed.

FIG. 5 shows a state in which the slider 25 is in the frontmost “fire extinguishing position” (a). In this state, the rear end of the slider 25 and the front end of the valve rod 17a of the main valve 17 in the closed state are shown. A small gap s is formed between the two. This small gap s is a "play stroke" when the slider 25 moves backward in the ignition operation direction.

The point fire extinguishing button 12 is supported by a fixed support frame 27 arranged and fixed at the front portion of the gas stove 1 so as to be swingable in the front-rear direction about the upper fulcrum shaft 28. The operation unit 12a provided on the back surface of the point fire extinguishing button 12 is abutted and supported by the front end of the slider 25 protruding from the gas valve block 15. Therefore, by pushing the point fire extinguishing button 12 backward, the slider 25 is moved backward against the spring 26, and the main valve 17 is opened and operated.

As shown in FIG. 5, the slider 25 has a frontmost "fire extinguishing position" (a) and a rearmost "ignition position" (a) by a push-push type position holding mechanism 30 provided at the lower part of the gas valve block 15. It is possible to switch and hold b) and the "combustion position" (c) in between.

That is, the position holding mechanism 30 includes a cam body 31 integrally connected to the slider 25 and a check member 32 formed by refracting the spring wire. The check member 32 is supported by the rear portion of the support case 24 so that it can only rotate laterally.

As shown in FIG. 9, a lateral heart-shaped loop-shaped groove cam 33 is formed on the lower surface of the cam body 31. The follow pin portion 32a, which is bent and formed at the front end of the restraining member 32, is elastically engaged with the groove cam 33.

Then, when the slider 25 is in the "fire extinguishing position" (a) protruding forward, the follow pin portion 32a is in the rear fire extinguishing position (e) of the groove cam 33, as shown in FIG. 9A. When the point fire extinguishing button 12 is pushed (pushed) to move the slider 25 from the "fire extinguishing position" (a) to the rear "ignition position" (b) against the spring-forced force, FIG. 9 (B) ), The follow pin portion 32a located at the rear end of the groove cam 33 moves forward relative to the cam body 31 and passes through the first path L1 of the groove cam 33 to the ignition position. It is guided by (f).

When the slider 25 moves to the "ignition position" (b), the valve rod 17a follows and moves, the main valve 17 is opened, and the safety valve 16 is opened. Further, the instrument plug switch (not shown) is turned on to start supplying power to the control unit and the control unit starts to operate, and the igniter switch (not shown) is turned on to turn on the first and second control units. The latch-type solenoid valves 18a and 18b are opened to supply fuel gas to the burner 4, and the ignition device 5 is operated to perform an ignition operation. When the ignition detection device 6 detects the ignition of the burner 4 by the ignition operation, the control unit keeps the safety valve 16 in the open state and continues the combustion of the stove burner 4.

After the ignition operation, when the hand is released from the point fire extinguishing button 12 and the pushing operation is released, the slider 25 returns and moves forward from the "ignition position" (b) by the force of the spring. At this time, as shown in FIG. 9C, the follow pin portion 32a is abutted and guided to the first step d1 formed at the bottom of the groove cam 33, and the second path is not returned to the first path L1. It is guided to L2 and is stably held at the combustion position (g) at the rear end of the second path L2. Then, when the slider 25 is in the "combustion position" (c), the main valve 17 is still sufficiently separated from the valve seat, fuel gas is continuously supplied, and the burner 4 is maintained in the combustion state. To.

To extinguish a fire, first, the point fire extinguishing button 12 is pushed to the limit again (push), and then the pushing operation is released. In this case, the slider 25 moves rearward from the "combustion position" (c) shown in FIG. 9 (C) as the point fire extinguishing button 12 is pushed in, but is formed at the bottom of the second path L2. Due to the second step d2, the follow pin portion 32a is guided by the third path L3 without returning to the second path L2 and moves relatively forward. Here, the front end of the third path L3 is set to a position where the slider 25 does not reach the "ignition position" (b), and the discharge ignition operation is not unnecessarily performed.

Next, when the operation of the point fire extinguishing button 12 is released, the slider 25 returns to the front "fire extinguishing position" (a) by the urging force of the spring 26, and at this time, it is formed at the bottom of the third route L3. The follow pin portion 32a is guided to the fourth path L4 without returning to the third path L3 and reaches the original "fire extinguishing position" (e) by the third step d3. A fourth step d4 is also formed on the rear bottom surface of the fourth path L4, and when the slider 25 is moved rearward from the "fire extinguishing position" (a), the follow pin portion 32a moves to the fourth step. It is contact-guided to d4 so that it can be correctly guided to the first route L1 without entering the fourth route L4.

When the slider 25 returns to the front "fire extinguishing position" (a) as described above, the main valve 17 is closed and the stove burner 4 is extinguished. Then, when the sliders 25 of all the point fire extinguishing buttons 12 including the grill are set to the "fire extinguishing position" (a), all the main valves 17 of each stove burner 4 are closed and the fire is extinguished, and all of each stove burner 4 are extinguished. The instrument plug switch is turned off, the safety valve 16 of each stove burner 4 is closed, and the first and second latch type solenoid valves 18a and 18b are closed. Further, the control unit stops the output of the power supply holding signal for holding the power supply state of the control unit, thereby ending the power supply to the control unit.

The above configuration is basically the same as the conventional structure, and in the present invention, a part of the user's body hits the point fire extinguishing button 12 and is pushed in, and the stove burner 4 and the grill burner are inadvertently ignited. The following structure is provided to prevent the above.

FIG. 2 is a perspective view of the point fire extinguishing operation unit including the point fire extinguishing button 12 as viewed from the front, FIG. 3 is a perspective view of the point fire extinguishing operation unit as viewed from the rear, and FIG. 4 is a point fire extinguishing operation unit. It is an exploded perspective view.

As shown in these figures, the fulcrum shaft 28 and the check pin 35 as a check protrusion are projected above and below the left and right side surfaces of the point fire extinguishing button 12, while a fixed support for supporting the point fire extinguishing button 12. Above and below the left and right side walls 27a of the frame 27, a fulcrum guide portion 36 for engaging and guiding the fulcrum shaft 28 and a check guide portion 37 for engaging and guiding the check pin 35 are formed.

The fulcrum guide portion 36 has a groove shape that penetrates through the fulcrum guide portion 36, and guides the inserted fulcrum shaft 28 so as to be vertically movable within a certain range. Further, the check guide portion 37 has a groove shape that penetrates through the vertical guide portion 37a that guides the inserted check pin 35 so as to be movable up and down within a certain range, and a front and rear guide portion that is connected rearward from the lower end of the vertical guide portion. It has 37b. The front-rear guide portion 37b is formed in an arc shape centered on the lower end portion of the fulcrum guide portion 36.

The point fire extinguishing button 12 at the point fire extinguishing position is set to the upper first position and the lower second position by the fulcrum guide portion 36 with which the fulcrum shaft 28 is engaged and the vertical guide portion 37a with which the check pin 35 is engaged. It can be moved up and down between.

Since the fulcrum guide portion 36 is formed in a portion of the fixed support frame 27 that cannot be elastically deformed on the left and right sides of the side wall 27a, the fulcrum shaft 28 passes through an opening formed in the upper and lower intermediate portions of the fulcrum guide portion 36. Is engaged with the fulcrum guide portion 36 from the rear. On the other hand, since the rear portion of the front-rear guide portion 37b in the restraint guide portion 37 is located on the rear end side of the side wall 27a extending in a rearward cantilever shape, the rear portion of the left and right side walls 27a is pushed laterally outward and deformed. The check pin 35 can be engaged with the rear portion of the front-rear guide portion 37b.

Further, a tension spring 38 as an urging means is attached over the spring receiving portion 12b projecting from the upper end of the point fire extinguishing button 12 and the spring receiving portion 27b provided at the upper end of the fixed support frame 27, and the point fire extinguishing button 12 is always pulled up and urged toward the first position above.

The point fire extinguishing button 12 supported as described above is operated as follows.

As shown in FIG. 5, in the state where the point fire extinguishing button 12 is in the "fire extinguishing position" protruding most forward, the point fire extinguishing button 12 pulled up and urged by the tension spring 38 is pulled upward to the first position. is there. In this first position, the fulcrum shaft 28 is engaged and held at the upper end of the fulcrum guide portion 36, and the check pin 35 is engaged and held at the upper end of the vertical guide portion 37a of the check guide portion 37.

Therefore, in this state, the restraint pin 35 engages with the upper part of the vertical guide portion 37a, so that the rotation of the point fire extinguishing button 12 about the axis of the fulcrum shaft 28 is prevented from engaging in the locked state. Yes, the point fire extinguishing button 12 does not rotate even if an external force in the rearward pushing direction, which is the ignition operation direction, is applied. That is, the movement in the ignition operation direction is restrained and prevented simply by the action of the pushing external force.

In the ignition operation, as shown in FIG. 6, first, the point fire extinguishing button 12 in the "fire extinguishing position" is pushed down against the spring-loaded force to move it to the second position. That is, the point fire extinguishing button 12 is operated downward in the vertical direction, which is a direction different from the ignition operation direction. As a result, the fulcrum shaft 28 moves to the lower end of the fulcrum guide portion 36, the check pin 35 moves to the lower end of the vertical guide portion 37a in the check guide portion 37, and the check pin 35 moves up and down in the second position. It reaches the lower end of the guide portion 37a.

Since the lower end of the vertical guide portion 37a in the check guide portion 37 is connected to the front-rear guide portion 37b extending in an arc shape around the lower end portion of the fulcrum guide portion 36, the check pin 35 reaching the lower end of the vertical guide portion 37a , Movement along the front-rear guide portion 37b is allowed. That is, the lock is released so that the point fire extinguishing button 12 can be moved in the pushing direction.

The check pins 35 projecting from the left and right side surfaces of the point fire extinguishing button 12 and the check guide portion 37 formed on the left and right side walls 27a of the fixed support frame 27 are used to ignite the point fire extinguishing button 12 at the fire extinguishing position. A locking means capable of switching between the locked state that prevents movement in the direction and the unlocked state that allows movement in the ignition operation direction is configured.

According to this locking means, the left and right sides of the wide point fire extinguishing button 12 are locked, so that the locking function is reliable, and even if an external force acts on the laterally biased part of the point fire extinguishing button 12, the point fire extinguishing is accurately performed. It is possible to prevent the button 12 from moving in the ignition operation direction.

Next, the point fire extinguishing button 12 that has been once pushed down and is in the unlocked state is continuously pushed to the rear "ignition position" for operation. As a result, the point fire extinguishing button 12 is swung backward about the axis p of the fulcrum shaft 28 received at the lower end of the fulcrum guide portion 36, and the check pin 35 is moved back and forth in an arc shape in the check guide portion 37. It moves backward along the guide portion 37b. Then, when the point fire extinguishing button 12 is pushed to the "ignition position", the check pin 35 reaches the rear end of the front / rear guide portion 37b as shown in FIG. 7.

When the finger is released from the point fire extinguishing button 12 after the ignition operation, the point fire extinguishing button 12 is returned to the "combustion position" slightly ahead of the "ignition position" and stably held by the position holding mechanism 30 as described above. To. At this time, as shown by the virtual line in FIG. 7, the check pin 35 is engaged at the front-rear intermediate position of the front-rear guide portion 37b, and the point fire extinguishing button 12 moves upward by the spring-forced force. Is blocked.

Then, after the point fire extinguishing button 12 is pushed in again from the "combustion position" and then the finger is released from the point fire extinguishing button 12, as described above, the point fire extinguishing button 12 becomes "forward return operation of the slider 25". It returns and swings from the "combustion position" to the "fire extinguishing position", and in conjunction with this, the check pin 35 moves forward along the front-rear guide portion 37b of the check guide portion 37. Then, when the point fire extinguishing button 12 returns and swings to the "fire extinguishing position", the check pin 35 reaches the front end of the front-rear guide portion 37b, that is, the second position which is the lower end of the vertical guide portion 37a. As a result, there are no restrictions on the upward movement of the check pin 35, and the point fire extinguishing button 12 moves to the upper first position by the pulling force of the pulling spring 38 and returns to the original position posture. That is, when the point fire extinguishing button 12 returns to the "fire extinguishing position", it is automatically reset to the locked state.

As described above, according to the present embodiment, when the point fire extinguishing button 12 is in the fire extinguishing position, it is always in the upper first position and is in the locked state, so that it is different from the ignition operation direction of the point fire extinguishing button 12. The point fire extinguishing button 12 cannot be pushed in unless the lock is released by operating downward in the direction. This prevents a part of the user's body from hitting the point fire extinguishing button 12 and unintentionally igniting. Further, in the fire extinguishing position, the point fire extinguishing button 12 is always in the locked state, so that it effectively functions as a child lock that is not forgotten to be locked.

In the above embodiment, the point fire extinguishing button 12 is spring-urged to the upper lock side by the tension spring 38, but the tension spring is not limited to the tension spring, and a wire spring, a torsion spring, a leaf spring, or the like may be used to urge the fire extinguishing button 12. Good.

As another embodiment of the present invention, as shown in FIG. 10, an opening 40 for incorporation may be formed in the front-rear middle of the front-rear guide portion 37b of the check guide portion 37. As a result, the check pin 35 can be easily assembled and engaged with the check guide unit 37.

Since only the upper edge of the front-rear guide portion 37b of the check guide portion 37 engages and guides the check pin 35 to restrain the upward movement of the point fire extinguishing button 12, as another embodiment of the present invention, FIG. As shown in 11, the front-rear guide portion 37b may be formed at the lower end edge of the side wall 27a.
