  By the way, as in Patent Document 1, in order to separately provide the point-extinguishing button and the heating power adjustment lever on the front panel, an opening for arranging the point-extinguishing button and an opening for arranging the heating power adjustment lever are separately provided on the front panel. Need to be formed. However, if the openings are formed at close positions, the strength of the portion between the openings of the front panel is reduced. On the other hand, if the openings are formed at positions apart from each other, a large area is required to arrange both the point-extinguishing button and the heating power adjusting lever on the front panel.

  Recently, a stove having a function of automatically controlling the heating power of the grill burner with a microcomputer or the like (so-called auto grill function) has been spreading. Some of these stoves are provided with a point-extinguishing button for a grill burner and an operation panel for setting on the front panel, and omitting a heating power adjusting lever for the grill burner. In order to reduce the manufacturing cost of the stove without the heating power adjusting lever, it is conceivable to use a front panel of the stove without the heating power adjusting lever as the front panel. However, when the front panel of a different model is also used in this way, if the heating power adjustment lever is omitted, the opening for placing the heating power adjustment lever formed on the front panel remains as a blank and the appearance is impaired. It is.

  The present invention has been made in view of the above circumstances, and can suppress a reduction in the strength of the front panel. Both the fire extinguishing button and the thermal power adjustment lever can be arranged in a narrow area, and the front panel is maintained while maintaining its aesthetic appearance. It is an object of the present invention to provide a stove that can also be used as a front panel of a stove that omits the heating power adjustment lever.

In order to solve the above-mentioned problems, the stove according to the present invention has, on the front panels 12 and 13, as the operation unit, the fire extinguishing buttons 14 a to 14 c for igniting and extinguishing the burners 3 a to 3 c and the thermal power of the burners 3 a to 3 c. In the stove provided with the heating power adjusting levers 15a to 15c to be adjusted, the operation panel openings 36a to 36c are provided in the front panels 12 and 13, and the point-extinguishing buttons 14a to 14c are provided in the operation part openings 36a to 36c. together but are disposed, said lever clearance 47a~47c ranging from edge to the point extinguishing button 14a~14c between the point extinguishing button 14a~14c the edge of the opening 36a~36c for the operating unit The heating power adjusting levers 15a to 15c are formed in the lever gaps 47a to 47c.

  With this configuration, the point-extinguishing buttons 14a to 14c and the thermal power adjusting levers 15a to 15c can be arranged in one operation portion opening 36a to 36c, so that the strength reduction of the front panels 12 and 13 can be suppressed. The buttons 14a to 14c and the heating power adjustment levers 15a to 15c can be arranged in a small area. Further, the front panels 12 and 13 provided with the operation portion openings 36a to 36c can be used as a front panel such as a stove having an auto grill function and omitting the heating power adjusting levers 15a to 15c. In this case, only the fire extinguishing button is arranged in the operation part opening 36c, and no fire power adjusting lever is arranged in the lever gap 47c. However, the lever gap is provided by arranging the point fire extinguishing button in the operation part opening 36c. 47c is a conspicuous gap. For this reason, aesthetics are not greatly impaired.

  Further, the point-extinguishing buttons 14a to 14c are pivotally supported so as to be pivotable back and forth, and have a push operation part 43 at a position in front of and below the pivotally supported part 41. The push operation part 43 The burners 3a to 3c are switched between ignition and extinguishing by pressing and operating the point extinguishing buttons 14a to 14c downward and rearward, and the lever gaps 47a to 47c are point extinguishing. Preferably, the heating power adjusting levers 15a to 15c are arranged between the buttons 14a to 14c and the upper edge portions of the operation portion openings 36a to 36c, and the lever clearances 47a to 47c are arranged. If it does in this way, in cleaning the dirt adhering on the point fire extinguishing button 14a-14c, by moving the heating power control lever 15a-15c suitably, and pushing the point extinguishing button 14a-14c, operation part opening 36a A relatively large gap for inserting a cleaning cloth or the like can be formed between the upper edge of .about.36c and the point fire extinguishing buttons 14a.about.14c, whereby the point extinguishing buttons 14a.about.14c can be easily cleaned. . Further, by arranging the thermal power adjustment levers 15a to 15c above the point fire extinguishing buttons 14a to 14c, the fire extinguishing buttons 14a to 14c become an obstacle when operating the thermal power adjustment levers 15a to 15c by extending their hands downward. It is difficult to operate the thermal power control levers 15a to 15c easily. Moreover, this can shorten the amount of forward projection of the thermal power adjusting levers 15a to 15c, and can improve the appearance.

  Further, the point-extinguishing buttons 14a to 14c are pivotally supported so as to be pivotable back and forth, and have a push operation portion 43 at a position in front of and above the pivotally supported portion 41. The ignition and extinguishing of the burners 3a to 3c are switched by pushing and turning the extinguishing buttons 14a to 14c upward and rearward, and the lever gaps 47a to 47c are switched to the extinguishing button 14a. It is preferable that the heating power adjusting levers 15a to 15c are arranged in the lever gaps 47a to 47c. In this way, by pressing and operating the fire extinguishing buttons 14a to 14c, it is possible to form a relatively large gap for inserting a cleaning cloth or the like above the heating power adjusting levers 15a to 15c. The upper surfaces of the thermal power control levers 15a to 15c can be easily cleaned. In addition, since the thermal power adjustment levers 15a to 15c are disposed below the point fire extinguishing buttons 14a to 14c, the thermal power adjustment levers 15a to 15c are obstructive when the hand is pushed down and the point fire extinguishing buttons 14a to 14c are pushed. It is difficult to switch between ignition and extinguishing of the burners 3a to 3c.

  The stove according to the present invention can suppress the strength reduction of the front panel, and both the point fire extinguishing button and the heating power adjusting lever can be arranged in a narrow area, and other parts of the front panel can be used effectively. In addition, the front panel can be used as a front panel of the stove without the fire power adjustment lever while maintaining the beauty.

During operation in the manual cooking mode, the valve holes 33 and 35 for the latch electromagnetic valves 32 and 34 are normally opened. When the cooking container is not detected by the corresponding container detection means 9, the valve holes 33 and 35 are closed by the latch electromagnetic valves 32 and 34 so that the burner 3a cannot be ignited even if the fire extinguishing button 14a is operated. It has become.

  The point-extinguishing button 14a is formed in a substantially rectangular shape when viewed from the front. As shown in FIG. 1, a pivotally supported portion 41 is pivotally supported around the left and right axis at the upper end of the rear portion of the point-extinguishing button 14 a and attached to the main body 1. The point-extinguishing button 14a is formed with a protruding portion 42 that protrudes forward, and the upper surface of the protruding portion 42 is a push operation portion 43 that is inclined forward and downward. The push operation unit 43 is disposed on the front side and the lower side of the pivoted support unit 41 in the point-extinguishing button 14a. Accordingly, when the push operation part 43 is pushed with a finger, the point-extinguishing button 14 a rotates downward and rearward with the pivoted part 41 as a center.

  A slider 44 that is slidable in the front-rear direction is provided at the lower part of the instrument plug body 21a. The slider 44 is disposed behind the point-extinguishing button 14a. When the point-extinguishing button 14a is pushed as described above, the slider 44 is pushed backward by the point-extinguishing button 14a and moves backward.

  The instrument plug body 21a is provided with a switching mechanism 45 that switches and holds the slider 44 between the forward position and the backward position. The switching mechanism 45 is a mechanism using a conventionally known heart-shaped cam and has a spring 46. In the state where the slider 44 is disposed at the forward movement position as shown in FIG. 1A, the fire extinguishing button 14a is disposed at the protruding position. In this state, when the push operation part 43 of the fire extinguisher button 14a is pushed, the slider 44 moves back to the last retracted position behind the retracted position against the spring 46 as shown in FIG. Thereafter, when the pressing force to the push operation unit 43 is released, the slider 44 moves forward to the retracted position by the urging force of the spring 46 as shown in FIG. 1B, and the fire extinguishing button 14a also moves forward together with the slider 44. It moves and is arranged at the push-in position rotated backward from the protruding position. Further, when the push operation unit 43 is pushed in the state in which the fire extinguishing button 14a is arranged at the push-in position in this way, the slider 44 moves back to the last retreat position as shown in FIG. When the pressing force applied to the push operation unit 43 is released, the slider 44 is advanced to the advanced position by the urging force of the spring 46 as shown in FIG. 1A, and the point-extinguishing button 14a is rotated to the protruding position together with the slider 44. Move. That is, the slider 44 is switched between a state where it is disposed at the retracted position and a state where it is disposed at the forward position every time the point-extinguishing button 14a is pushed.

  The instrument plug body 21 a is provided with a valve rod 48 whose rear side is inserted into the gas flow path 22. The valve rod 48 is connected to the slider 44 and moves back and forth as the slider 44 advances and retreats. A main valve 28 for opening and closing the valve hole 29 is provided in the middle of the valve rod 48. The main valve 28 closes the valve hole 29 when the slider 44 is disposed at the forward movement position, and opens the valve hole 29 when the slider 44 is disposed behind the forward movement position.

  The safety valve 25 is composed of an electromagnetic valve. In the energized state, the valve body 50 is sucked by the solenoid 49 and the valve hole 26 is maintained open. In the non-energized state, the valve body 50 is moved forward by a biasing force of a spring (not shown). Then, the valve hole 26 is closed by the valve body 50.

  The instrument plug main body 21 a is provided with an instrument plug switch (not shown) that is switched ON / OFF according to the front-rear position of the slider 44. The instrument plug switch is turned on when the slider 44 is disposed at the rearward position and rearward thereof, and is turned off when the slider 44 is disposed at the forward movement position.

  When the appliance plug switch is turned on, the control unit starts energizing the safety valve 25 and drives the ignition device 10 of the burner 3a. When the appliance plug switch is turned off, the controller stops energizing the safety valve 25 and opens the valve hole 26. close up.

  Further, the control unit maintains the energized state of the safety valve 25 only when the flame is detected by the ignition detection device 11, and shuts off the energization to the safety valve 25 and closes the valve hole 26 when the flame is no longer detected. . For this reason, the fuel gas can be prevented from flowing out when it disappears due to spillage or wind and the flame is no longer detected by the ignition detector 11. The control unit also determines that an abnormality such as burning or scorching has occurred even when the temperature of the lower surface of the cooking container detected by the temperature sensor 4 reaches a predetermined temperature (for example, 250 ° C.). Then, the power supply to the safety valve 25 is cut off and the valve hole 26 is closed.

  In order to ignite the burner 3a, the push operation part 43 of the point-extinguishing button 14a arranged at the protruding position is pushed. Then, the slider 44 moves from the advance position to the retreat position through the last retreat position, the valve hole 50 for the main valve 28 is opened, and the valve body 50 is moved backward by the retreating valve rod 48 so that the valve hole 26 is opened. As a result, the fuel gas is supplied from the gas supply path 18 to the burner 3a through the appliance plug 20a. At this time, the appliance plug switch is turned on, the ignition device 10 is driven to ignite the burner 3a, and the safety valve 25 is energized.

  In order to extinguish the burner 3a, the push operation unit 43 of the point fire extinguishing button 14a arranged at the pushing position is pushed. Then, the slider 44 moves from the retracted position to the advanced position through the final retracted position, and the valve hole 29 is closed by the main valve 28. Further, the appliance plug switch is turned off, and the power supply to the safety valve 25 is cut off. Thereby, the supply of the fuel gas to the burner 3a is cut off, and the burner 3a is extinguished.

  The thermal power adjustment lever 15a is pivotally supported by a pivotal support 40 provided at the upper part of the instrument plug body 21a so as to be rotatable about the vertical axis. The pivotal support portion 40 is disposed behind the point-extinguishing button 14a. A knob 52 (see FIG. 2 and the like) operated by a finger is provided at the front end of the thermal power adjustment lever 15a. The thermal power adjustment lever 15a moves to the left and right by moving the knob 52 left and right. To turn. In addition, illustration of the knob | pick part 52 is abbreviate | omitted in FIG.

  A flow rate control valve 38 that is linked to the heating power adjusting lever 15a is provided on the upper part of the instrument plug body 21a. The flow control valve 38 is constituted by a needle that can slide in the front-rear direction with respect to the instrument plug body 21a. The size of the gap formed between the flow control valve 38 and the valve hole 39 varies depending on the front and rear positions thereof, and the size of the gap increases as the flow control valve 38 is positioned forward. For this reason, the flow rate of the fuel gas supplied to the downstream side increases as the flow rate control valve 38 is positioned forward.

  A pin 53 protruding upward is provided at the front end of the flow control valve 38. The upper end of the pin 53 is inserted into an insertion hole 54 formed in the heating power adjustment lever 15a. The insertion hole 54 is located in front of the pivotal support 40 that is the center of rotation of the thermal power adjusting lever 15a, and is formed in an arc shape that approaches the pivotal support 40 as it goes to the right in plan view. Therefore, the flow rate control valve 38 moves forward when the thermal power adjustment lever 15a rotates to the right side, and the flow rate control valve 38 moves backward when the thermal power adjustment lever 15a rotates to the left side. The advance amount of the flow rate control valve 38 at this time increases as the amount of rotation of the heating power adjustment lever 15a to the right increases. Accordingly, the amount of fuel gas supplied to the burner 3a, and hence the heating power of the burner 3a, can be adjusted by adjusting the amount of rotation of the heating power adjusting lever 15a.

  When the point-extinguishing buttons 14a to 14c and the heating power adjusting levers 15a to 15c are provided, the left front panel 12 is formed with an operation portion opening 36a for the stove burner-3a, and the right front panel 13 is provided with a stove. An operation portion opening 36b for the burner 3b and an operation portion opening 36c for the grill burner 3c are provided.

  Each operation part opening 36a-36c consists of a hole of a rectangular shape in front view, and the corresponding point-extinguishing button 14a-14c is arrange | positioned at each operation part opening 36a-36c.

  Each point fire-extinguishing button 14a-14c is arrange | positioned in the lower position of corresponding operation part opening 36a-36c in the state which made the protrusion part 42 protrude ahead of the front panel 12 or 13. FIG. A slight gap is formed between each of the point-extinguishing buttons 14a to 14c and the left and right and lower edges of the corresponding operation unit openings 36a to 36c to allow the operation of the point-extinguishing buttons 14a to 14c. However, between the point fire extinguishing buttons 14a to 14c and the upper edge portions of the operation portion openings 36a to 36c, the substantially rectangular lever gaps 47a to 47c that are slightly wider than the other portions and that are longer to the left and right. Is formed.

  The corresponding thermal power adjusting levers 15a to 15c are passed through the lever gaps 47a to 47c having a width extending from the point fire extinguishing buttons 14a to 14c to the upper edges of the operation unit openings 36a to 36c, and the respective thermal power adjustments are performed. The knob 52 of the levers 15 a to 15 c is disposed in front of the front panel 12 or 13. When the thermal power control levers 15a to 15c are operated, the front ends thereof are moved in the lever gaps 47a to 47c in parallel with the longitudinal direction of the lever gaps 47a to 47c.

  As described above, the point-extinguishing buttons 14a to 14c are arranged in the operation unit openings 36a to 36c of the front panels 12 and 13, and between the edge of the operation unit opening 36a to 36c and the point-extinguishing buttons 14a to 14c. Since the heating power adjusting levers 15a to 15c are arranged in the formed lever gaps 47a to 47c, an opening for arranging the point-extinguishing buttons 14a to 14c on the front panels 12 and 13 as in the prior art, and the heating power adjusting lever 15a, respectively. There is no need to separately form openings for placing ~ 15c. For this reason, the strength reduction of the front panels 12 and 13 can be suppressed. Moreover, both the point-extinguishing buttons 14a to 14c and the heating power adjusting levers 15a to 15c can be arranged in a narrow area.

  Moreover, the stove front panel 13 of the present embodiment can be used as a stove front panel having a so-called auto grill function and omitting the heating power adjusting lever. In this case, only the fire extinguishing button for the grill burner is arranged in the operation portion opening 36c and nothing is arranged in the portion of the lever gap 47c, but this portion is in the operation portion opening 36c. It becomes a conspicuous gap by arranging. Therefore, the front panel 13 can be used as a front panel of the stove without the fire power adjusting lever without greatly deteriorating the beauty.

  Further, in the stove according to the present embodiment, the push operation portion 43 of the point-extinguishing buttons 14a to 14c is arranged at a position on the front side and the lower side of the pivoted portion 41 of the point-extinguishing buttons 14a to 14c. 47c is formed between the point-extinguishing buttons 14a to 14c and the upper edges of the operation unit openings 36a to 36c. For this reason, when cleaning the dirt adhering to the fire extinguishing buttons 14a to 14c, the heating power adjusting levers 15a to 15c are appropriately moved in the left-right direction, and the operating part opening is operated by pressing the fire extinguishing buttons 14a to 14c. A relatively large gap for inserting a cleaning cloth or the like can be formed between the upper edges of 36a to 36c and the point extinguishing buttons 14a to 14c, and the point extinguishing buttons 14a to 14c can be easily cleaned. There are also advantages.

  That is, as shown in the reference example of FIG. 8, when the opening 60 for the fire extinguishing button 14a ′ and the opening 61 for the fire power adjustment lever 15a ′ are separately provided on the front panel 12 ′, as shown in FIG. Thus, the dimension of the gap formed between the upper edge of the opening 61 and the thermal power adjustment lever 15a ′ is Ga ′, and the dimension of the gap formed between the lower edge of the opening 61 and the thermal power adjustment lever 15a ′ is Gb. ′, The thickness of the heating power adjusting lever 15a ′ is T ′, the size of the gap formed between the upper edge of the opening 60 and the point-extinguishing button 14a ′ is Gc ′, and the point-extinguishing button as shown in FIG. When the increase in Gc ′ when pressing 14a ′ is ΔGc ′ and G ′ is the size of the gap for inserting a cleaning cloth or the like formed above the pressed fire extinguishing button 14a ′, G ′ = Gc ′ + ΔGc ′. On the other hand, in the case of the stove according to the present embodiment, as shown in the explanatory diagram of FIG. 6A, the dimension of the gap between the upper edge of the operation portion opening 36a and the heating power adjustment lever 15a is Ga, and the heating power adjustment. The clearance between the lever 15a and the point-extinguishing button 14a is Gd, the thickness of the heating power adjusting lever 15a is T, and the point-extinguishing button 14a is cleaned to clean the upper surface of the point-extinguishing button 14a as shown in FIG. The amount of increase in Gd when pressing is set to ΔGd, and the thermal power adjustment levers 15a to 15c are appropriately moved in the left and right directions so that the thermal power adjustment levers 15a to 15c are not located above the portion to be cleaned of the fire extinguishing button 14a When the point extinguishing button 14a is pushed in, the size of the gap for inserting a cleaning cloth or the like formed above the point extinguishing button 14a, that is, the opening for the operation unit from the point extinguishing button 14a. When the distance to the upper edge of 6a and G, the G = Ga + T + Gd + ΔGd. Since Ga = Ga ′, T = T ′, Gd≈Gc ′, and ΔGd≈ΔGc ′, G is approximately Ga + T larger than G ′. Therefore, the dirt adhering to the point fire buttons 14a to 14c can be easily cleaned.

  Further, by arranging the fire power adjusting levers 15a to 15c above the fire extinguishing buttons 14a to 14c as described above, when the fire power adjusting levers 15a to 15c are operated with the hand extended downward, the fire extinguishing buttons 14a to 14c are operated. Is easy to operate the fire power adjusting levers 15a to 15c. Moreover, this can shorten the amount of forward projection of the thermal power adjustment levers 15a to 15c.

  In the above-described embodiment, the heating power adjusting levers 15a to 15c are arranged on the point-extinguishing buttons 14a to 14c in the operation unit openings 36a to 36c, but the present invention is not limited to this, and the operation unit openings 36a to 36c are not limited thereto. In 36c, lever gaps 47a to 47c may be formed below, to the left, or to the right of the point fire buttons 14a to 14c, and the heating power adjustment levers 15a to 15c may be disposed in the lever gaps 47a to 47c.

  Further, when the heating power adjusting levers 15a to 15c are arranged below the point-extinguishing buttons 14a to 14c in the operation unit openings 36a to 36c, the push operation unit 43 of the point-extinguishing buttons 14a to 14c is used as the point-extinguishing button as shown in FIG. Lever gaps 47a to 47c disposed between the point-extinguishing buttons 14a to 14c and the lower edge portions of the operation unit openings 36a to 36c, which are disposed in front of and above the pivoted support part 41 of 14a to 14c. It is also preferable that the thermal power adjustment levers 15a to 15c are arranged in the middle. In this example, by pressing and operating the fire extinguishing buttons 14a to 14c, a relatively large gap for inserting a cleaning cloth or the like can be formed above the thermal power adjustment levers 15a to 15c. The upper surfaces of the adjustment levers 15a to 15c can be easily cleaned. In addition, since the thermal power adjustment levers 15a to 15c are arranged below the point-extinguishing buttons 14a to 14c, the thermal power adjustment lever is used when the hand is extended downward and the point-extinguishing buttons 14a to 14c are extended and pushed. 15a-15c becomes difficult to get in the way. In addition, since the stove of this example has the structure similar to the said embodiment, detailed description is abbreviate | omitted.
