Description

  The present invention relates to a gas cooker, and more particularly to control of the combustion flow rate thereof.

Conventionally, this type of apparatus is generally as shown in Patent Document 1. As shown in FIG. 54, this apparatus is configured to control the temperature when the pan bottom temperature sensor 2 is mounted on the stove burner 1 and “tempura” is set. By the operation of the control circuit of FIG. When the pan bottom temperature becomes higher than the set temperature, the solenoid valve 3 in the gas control path of FIG. 54 is closed to the minimum flow rate of the bypass nozzle 4, and when the pan bottom temperature falls below the set temperature, the solenoid valve 3 is opened and strong. It was supposed to be burning.
JP-A-3-236518

  However, the flow rate control method using a conventional solenoid valve has HI-LOW control, and therefore has a problem in that the combustion suddenly shifts from the minimum flow rate to strong combustion and the flame suddenly increases.

  In addition, there was a problem that no consideration was given to a soft program that consciously reminds the user of a sudden flame change.

  In order to solve the above problems, the present invention includes a heating means for heating a pan, a heating control means for controlling the heating means, a temperature detection means for detecting the temperature of the pot, and an ignition button for performing an ignition / extinguishing operation. The heating control means includes a control circuit that outputs a control signal based on a temperature signal from the temperature detection means and an operation signal from an operation panel, and automatically adjusts the thermal power based on the output from the control circuit. An electric drive device that performs thermal power adjustment manually, and a flow rate adjustment device that is driven by the electric drive device or the thermal power adjustment button to perform thermal power adjustment, and the thermal power adjustment is performed by the flow rate adjustment device. When determining whether or not the heating power adjustment direction is the up direction, and setting the heating power adjustment speed based on the determination result, if it is determined that the heating power adjustment direction is the up direction, Tsu as compared with the case not flop direction is obtained so as to gradually change.

  According to this configuration, the configuration can be simplified by combining the flow rate control mechanism using the thermal power control button and the flow rate control device of the heating control means, and the thermal power control method is a button. Thus, it is not necessary to secure a space for sliding, and can be collected in a compact shape. In addition, since it can be driven by two methods, manual and electric, and only one flow rate adjusting device is required, for example, when there are two flow rate adjusting devices, a weak flow rate is set by manual heating power adjustment, and a low flow rate is also achieved by electric drive. When set, the minimum flow rate causes a flow pressure loss, and the flow rate is reduced more than necessary. As a result, if the supply gas pressure is low, a stable flame cannot be secured and a misfire may occur. In anticipation of this state, the minimum flow rate may be set larger, and the minimum calorie necessary for cooking, for example, 400 Kcal / h may not be obtained. However, these factors can be eliminated by configuring a single flow rate adjusting device. Of course, the number of components can be reduced, and it can be provided at low cost. Of course, the number of components is reduced, and there is an effect that it can be provided at a low cost.

Further, when the thermal power adjustment is performed via the flow rate adjusting means, it is determined whether or not the thermal power adjustment direction is the upward direction, the thermal power adjustment speed is set based on the determination result, and the thermal power adjustment direction is the upward direction. If it is determined that, the flame is gradually changed compared to the case where it is not in the up direction, it is possible to alert the user that the flame gradually changes and the flame becomes larger.

  The gas cooker according to claim 1 of the present invention combines the flow rate control mechanism using the thermal power control button and the flow rate control device using the electric drive device, so that the configuration can be simplified and the thermal power control can be performed. Since the method is a button, it is not necessary to secure a space for sliding unlike a thermal power adjustment lever, and it can be put together in a compact shape. In addition, since it can be driven by two methods, manual and electric, and only one flow rate adjusting device is required, for example, when there are two flow rate adjusting devices, a weak flow rate is set by manual heating power adjustment, and a low flow rate is also achieved by electric drive. When set, the minimum flow rate causes a flow pressure loss, and the flow rate becomes smaller than the required amount. However, the minimum flow rate can be stably provided without this. In addition, the number of components can be reduced and it can be provided at low cost. Further, when the thermal power adjustment is performed via the flow rate adjusting means, it is determined whether or not the thermal power adjustment direction is the upward direction, the thermal power adjustment speed is set based on the determination result, and the thermal power adjustment direction is the upward direction. If it is determined that, the flame is gradually changed compared to the case where it is not in the up direction, it is possible to alert the user that the flame gradually changes and the flame becomes larger.

  Further, in the gas cooker according to claim 2, when the heating power is changed by the electric drive device, the heating power adjustment button is also moved to the changed heating power position, and the user can easily determine the current heating power.

  In addition, the gas cooker according to claim 3 can minimize the area of the operation panel as compared with the case of the heat control lever. In addition, the design can be compacted.

  In addition, the gas cooker according to the fourth aspect can minimize the area of the operation panel by providing a variety of operations such as electric drive for ignition / extinguishing / thermal power adjustment, manual operation with one button. In addition, the design can be compacted.

  In addition, since the gas cooker according to claim 5 uses a governor, the set secondary gas pressure has a characteristic that is constant even when the primary gas pressure fluctuates, and stable thermal power control can be performed. .

  In addition, the gas cooker according to claim 6 can provide a product that can be attached only by partially changing the piping of a popular stove with a tempura fire prevention function, which is generally spreading. Gas species can be easily changed.

  In the gas cooker according to claim 7, for example, in the case of a calorie with a low calorie of 400 Kcal / h, the governor pressure becomes a very small gas pressure, and it is difficult to adjust this from the diaphragm temperature characteristics, the spring constant, etc. However, the minimum flow rate can be easily secured by the bypass hole, and unnecessary fire extinguishing and low calorie variation can be suppressed.

  The gas cooker according to claim 8 can control the minimum flow rate normally by pressing the needle against the needle receiver, and when the needle hits the needle receiver and the electric drive device is rotated, the electric drive device is overloaded. Can be added to prevent destruction.

  The gas cooker according to claim 9 can control the minimum flow rate by pressing the needle against the needle receiver, and overloads the electric drive apparatus when the needle hits the needle receiver and the electric drive apparatus is rotated. Can be more effectively prevented from being destroyed.

The gas cooker according to claim 10 can control the minimum flow rate normally by pressing the needle against the needle receiver, and when the needle hits the needle receiver and the electric drive device is rotated, the electric drive device is overloaded. Can be more effectively prevented from being destroyed.

It is not necessary to secure a space for use, and it can be collected in a compact shape. In addition, since it can be driven by two methods, manual and electric, and only one flow rate adjusting device is required, for example, when there are two flow rate adjusting devices, a weak flow rate is set by manual heating power adjustment, and a low flow rate is also achieved by electric drive. When set, the minimum flow rate causes a flow pressure loss, and the flow rate is reduced more than necessary. As a result, if the supply gas pressure is low, a stable flame cannot be secured and a misfire may occur. In anticipation of this state, the minimum flow rate may be set larger, and the minimum calorie necessary for cooking, for example, 400 Kcal / h may not be obtained. However, these factors can be eliminated by configuring a single flow rate adjusting device. Of course, the number of components can be reduced, and it can be provided at low cost.

The output 47 for setting the “thermal power position” is sent to the next stage, and when not so, the process returns to “sensor temperature> non-stick temperature” 38.

  As described above, from the correlation between the temperature of the pan bottom temperature sensor 2 and the non-burning temperature, the heating control means 24 can appropriately select weak, medium and strong heating power.

  FIG. 7 shows a schematic flow of the overheat prevention determination means 29, where it is determined whether “sensor temperature> overheat prevention temperature−10 ° C.” 48, and in that case, an output for setting the flow rate control device 17 to “low heat power position” is obtained. 49, it is determined whether “sensor temperature> overheat prevention temperature” 50, in which case “safety valve OFF” is output to the next stage 51, and output 52 for setting the flow control device 17 to “high heat power position” is set to the next stage.

  As described above, from the correlation between the temperature of the pan bottom temperature sensor 2 and the set temperature of the temperature adjusting function, the heating control means 24 can appropriately select weak, medium and strong heating power.

  FIG. 9 shows an example of a schematic flow of the drive determining means 31. It is determined whether the sensor temperature is normal (sensor disconnection, short circuit, etc.) 67. If abnormal, the process goes to an abnormal processing route 68 described later. It is determined whether the counter electromotive force is normal 69. If abnormal, it goes to an abnormality processing route 68, which will be described later. If normal, it is determined whether ignition is the first ignition 70. If it is not a position, an output to make it a “strong heating power position” is output 72.

If it is not the first time, it is determined 70. If it is not the first time, it is determined from the previous stage whether there is a change in thermal power 73, if it is present, it is determined whether the current thermal power is different from the changed thermal power 74. 75, if yes, output 76 to “strong thermal power position”, otherwise determine whether the modified thermal power is medium thermal power 77, otherwise output 78 to output medium thermal power position, otherwise low thermal power Output to position 79.

In the abnormality processing route 68, the safety valve output is turned OFF 86, the notification means is turned ON 87, and the process is ended 88.

  As described above, the heating power can be surely adjusted to the target heating power position, and when the heating power is increased from weak to strong, the heating power can be slowly increased.

  FIG. 10 shows another example of the schematic flow of the drive determination unit 31. The same contents as those in FIG. 9 are denoted by the same reference numerals, description thereof is omitted, and only different parts are described.

  It is determined whether the ignition is the first time 70, and if it is the first time, it is determined whether the electric drive unit 18 is not at the central stop position 89. If not, the central stop position output is turned ON 90, the operation goes to the electric timer ON 91 to determine whether the central stop position is reached. If not, it is determined whether or not X seconds have elapsed, and if it has elapsed, the process goes to the abnormality processing route 68.

  It is determined whether or not the target position has been reached by changing the normal heating power 84. If the target position is reached, the process goes to the central stop position output ON 90. If not, it is determined whether or not X seconds have elapsed 85, and 1 is elapsed. Whether it is the first time is determined 94, and in the case of the first time, the central stop position output is turned ON 90. If it is not the first time, go to the abnormality processing route 68.

  As described above, in this case, in addition to the operation of FIG. 9, the electric drive device 18 can always be returned to the central stop position after the heating power is changed. Further, when the electric drive device 18 does not reach the target thermal power position due to some trouble, the electric drive device 18 is returned to the central stop position so that manual thermal power adjustment can be performed as will be described later.

  FIG. 11 shows still another example of the schematic flow of the drive determination unit 31. The same contents as those in FIG. 10 are denoted by the same reference numerals, description thereof is omitted, and only different parts are described.

  When the thermal power is changed and the current thermal power is different from the changed thermal power 74, when the current thermal power is neither strong nor weak thermal power 95, the current thermal power position is stored 96, and the process proceeds to the next stage. If the current thermal power is strong or weak, 97 is set as the memorized thermal power position.

  As described above, in this case, by storing the thermal power other than the strong and weak thermal power positions before the change, it is possible to return to the medium thermal power position of the original stored thermal power after moving the weak thermal power position. .

  12 and 13 show an embodiment of the electric drive device 18 and the flow rate control device 17 of the heating control means 24, and shows a case where a governor mechanism is used for the flow rate control device 17. FIG. FIG. 12 is a three-dimensional perspective view of the electric drive device 18 and the flow rate control device 17, and FIG. 13 is a cross-sectional view of a main part of the governor type flow rate control device 17.

  The electric drive device 18 includes a geared motor 98, a geared motor mounting frame 98-1, a switch element 99, a cam 101 having a switch element operation piece 100, and a spring A102. A flow control device 17 includes a governor body 103, a diaphragm 104, A spring B105, a valve 106, a protective plate 107, and a governor pin 108 are included.

  The heating control means 24 changes the governor secondary pressure by changing the spring load of the spring B105 by pressing the governor pin 108 with the force by which the diaphragm 104 pushes up the spring B105 by the gas pressure. The heating power is adjusted by changing the pressing stroke of the governor pin 108 by rotating.

  At this time, the thermal power setting (strong / weak) position is set by turning the switch element 99 on and off by the switch element operating piece 100 provided on the cam 101.

  In the figure, reference numeral 4 denotes a bypass nozzle 4, which may or may not be used. This is a diagram when used for the purpose of improving the accuracy of the minimum flow rate.

  FIG. 14 shows the cam rotation angle on the horizontal axis, the change in the secondary gas pressure (thermal power change state), the cam shape, and the ON / OFF state of the switch element 99 on the vertical axis. For example, at the low thermal power position, only the SW1 of the switch element 99 is in the ON state and the gas pressure is low, and when at the high thermal power position, only the SW2 is in the ON state and the gas pressure is high. Here, the cam shapes related to the thermal power adjustment are represented by A curve and B curve, and the respective gas pressure curves are represented by A curve and B curve. However, when the geared motor 98 is rotated at a constant speed, the low heat power increases to the high fire power. In order to call attention to the change of the heating power to the force, the cam shape of the B curve that raises the heating power while gradually changing and consciousness is more suitable than the shape of the A curve. The cam shape is adopted, and it takes about 2 seconds to change from low heat power to high heat power.

  As described above, it is possible to change the heating power with the electric drive device 18, and even if the electric drive device 18 is driven at a constant speed by devising the shape of the cam 101, the amount of change in the flame is initially suppressed and the flame is given to the user. It will be possible to raise awareness. Further, since the flow rate control device 17 is a governor system, even if the primary gas pressure changes, the secondary gas pressure can be expected to have the same thermal power, and stable thermal power performance can be provided.

  15 to 16 show an example in which the number of switch elements 99 is two and the medium heating power position can be detected. FIG. 15 is a perspective view showing a means for providing the medium heating power position. The operating pieces 100A and 100B and the medium heating power position switch element operating piece 100A + B are provided.

  FIG. 16 shows the flow rate when the cam 101 is used. The cam angle on the horizontal axis has a low thermal power position, a medium thermal power position, and a strong thermal power position. Stroke change amount and the ON-OFF state of the switch element 99-1 (SW1) and the switch element 99-2 (SW2).

The following (Table 1) shows the relationship between the mode of the switch element 99-1 (SW1) and the switch element 99-2 (SW2) and the thermal power position, and indicates that the mode 2 and the mode 4 cannot be distinguished. . For example, when the mode 1 is shifted to the mode 3, the mode 2 is changed to the mode 3 and the driving device is turned off. When the driving device is rotated by repulsive force and cannot be stopped suddenly, the mode 4 is set. In this case, it is necessary for the drive determination means 31 to determine that both the switch element 99-1 (SW1) and the switch element 99-2 (SW2) are ON, and to reverse the drive direction to shift to mode 3. When the power is turned off at modes 2 and 4, the current position is unknown whether mode 2 or mode 4. Therefore, it is indicated that when the power source is switched from OFF to ON, it is necessary for the drive determination means 31 to operate the electric drive device 18 in the heating power UP direction to shift the mode to 5.

  As described above, in this example, even if there are two switch elements 99, it is possible to confirm the weak, strong, medium thermal power position, the switch element 99 and the wiring processing related thereto can be reduced, and the number of parts can be reduced. The frequency of failure is reduced and the economic merit is high.

  However, the two switch elements 99 cannot discriminate the intermediate position, and there is inconvenience that a device for use in the heating control means 24 is required.

  17 to 18 show an example in which the middle heating power position is detected using three switch elements 99. FIG. 17 is a perspective view showing a means for providing the middle heating power position. The operation pieces 100A and 100B are provided with a switch element operation piece 100C for medium heating power position and a switch element operation piece 100A + B + C for medium heating power position, and the switch element operation piece 100C is continuous from a low heating power position to a medium heating power position. .

  FIG. 18 shows the flow rate when the cam 101 is used. The rotation angle of the cam 101 on the horizontal axis includes a weak thermal power position, a medium thermal power position, and a strong thermal power position. And the ON / OFF state of the switch element 99-1 (SW1), the switch element 99-2 (SW2), and the switch element 99-3 (SW3).

  The following (Table 2) shows the relationship between the modes of the switch elements 99-1 (SW1), 99-2 (SW2), 99-3 (SW3) and the thermal power position. Indicates that it can be determined. For example, when the mode 1 is shifted to the mode 3, the mode 2 is changed to the mode 3 and the driving device is turned off. When the driving device is rotated by repulsive force and cannot be stopped suddenly, the mode 4 is set.

  In this case, the switch element 99-3 (SW3) is in an OFF state, and when the drive determination means 31 outputs an output for shifting to mode 3, the heating control means 24 can immediately determine the rotation direction from the current position to the target position. To move directly to the target position. Further, when the power is turned off in mode 2, it is only necessary to immediately instruct the movement mode by the drive determination means 31 even when the power is turned on.

  As described above, in this example, by using three switch elements 99, the current position can be determined at any position and can be moved to the target heating power in a short time, and the control method of the heating control means 24 can be simplified. There is.

  FIG. 19 is a structural diagram of the cam 101 showing another example of the variable configuration of the medium heating power position. The cam 101 has a fixed switch element operating piece 100B for a low thermal power position, a switch element operating piece 100A for a high thermal power position, and a fixing screw hole 109, and a cam B101-1 for a medium thermal power position. Is provided with an adjustment hole 110 for fixing to the switch element operating pieces 100C, 100A + B + C and the cam 101, and is movably fixed by screws 101-2.

  In FIG. 20, the cam B101-1 is provided with a scale around the adjustment hole 110 to show that the set position can be discriminated.

  FIG. 21 shows the rotation angle of the cam B on the horizontal axis and the amount of gas combustion on the vertical axis. When the cam shape is the same, even if the governor spring B105 is selected for each gas type, Thus, the values of the weak combustion amount and the strong combustion amount are different from the burner combustion capability and the combustion properties of the individual gases, and it is indicated that it is necessary to move the middle thermal power position when the same thermal power is used.

  For example, in the case of 13A, the high thermal power is 4000 Kcal / h, the low thermal power is 400 Kcal / h, and the medium thermal power is 1500 Kcal / h. In order to set the medium thermal power to 1500 Kcal / h, point B, for L1, the strong thermal power is 3200 Kcal / h, the weak thermal power is 600 Kcal / h, and the medium thermal power is 1500 Kcal / h, point C. It becomes.

  Therefore, the scale position of the adjustment hole 110 where the medium heating power is the same calorie for each gas is confirmed in advance, and at the time of shipment from the factory, shipment can be performed according to the scale of the adjustment hole 110 suitable for each gas.

  22 to 30 show other examples of the electric drive device 18 of the heating control means 24 and the flow rate control device 17, and show an example in which a needle mechanism is used for the flow rate control device 17.

  FIG. 22 shows a block configuration together with FIGS. 23A and 23B. The electric drive unit 18 includes a geared motor 98, a plurality of switch elements 99, a geared motor mounting frame 98-1, on which these components are mounted, a spring C112, and a cam. The flow rate control device 17 is constituted by a needle receiver 113 into which a needle 111 is inserted.

The geared motor 98 puts the connecting pin 114 at its tip a into the slot 115 of the cam 101 and rotates it with a connection having a degree of freedom in the vertical direction. The cam 101 has a fixed switch element operating piece 100 for a low thermal power position, a switch element operating piece 100 for a high thermal power position, and a cam groove 117 for moving a needle pin 116 provided on the needle 111 in the vertical direction. The cam groove 117 is configured such that the needle pin 116 is always pressed against the needle receiver 113 by the spring C112. The needle 111 is provided with an O-ring 118.

  When the cam 101 is rotated, the flow rate adjusting device 17 adjusts the heating power while changing the passage area, and finally comes into contact with the needle receiver 113. When the cam 101 is further rotated, the cam 101 keeps the needle position constant against the spring C112, and the connecting gap between the connecting pin 114 at the tip a of the geared motor 98 and the slit 115 of the cam 101 is reduced, thereby destroying the device. The needle 111 is pressed against the needle receiver 113 to ensure the accuracy of the minimum flow rate.

  FIG. 24 shows the rotation angle of the cam 101 on the horizontal axis, the change of the secondary gas pressure (thermal power change state), the cam shape state, and the ON / OFF state of the switch element 99 on the vertical axis. At the low thermal power position, only the switch element 99-1 (SW1) is in the ON state and the gas pressure is low, and when at the high thermal power position, only the SW2 is in the ON state and the gas pressure is high. Here, the cam shapes related to the thermal power adjustment are represented by A curve and B curve, and the respective gas pressure curves are represented by A curve and B curve. However, when the geared motor 98 is rotated at a constant speed, the low heat power increases to the high fire power. In order to call attention to the change of the heating power to the force, the B-curve cam shape that raises the heating power while gradually changing and consciousness is more suitable than the A-curve cam shape. In this embodiment, this B-curve The cam shape is adopted, and it takes about 2 seconds to change to strong heat.

  As described above, even in this example, it is possible to change the heating power by the electric drive device 18 and, even if the electric drive device 18 is driven at a constant speed by devising the cam shape, the amount of change in the flame is initially suppressed to the user. It is possible to raise awareness that the flame becomes larger.

  FIG. 25 is a perspective view showing a means for providing a medium heating power position. The content is the same as FIG.

  FIG. 26 shows an example in which the middle heating power position is detected by using three switch elements 99, and the contents are the same as those in FIG.

  FIG. 27 is a perspective view of the cam 101 showing another example of the variable configuration of the medium heating power position, and the content is the same as FIG.

  FIG. 28 shows a block configuration of the electric drive device 18 and the flow rate control device 17 together with FIG. 29. The electric drive device 18 includes a geared motor 98, a plurality of switch elements 99, a geared motor attachment frame 98-1 for attaching these components, and a cam 101. The flow rate control device 17 includes a needle 111 having a needle pin 116 and an O-ring 118, a needle receiving body 119 into which the needle 111 is inserted, a needle receiving 113 having an O-ring inserted into the needle receiving body 119 from below, a needle It comprises a spring D120 that supports the receiver 113 in the needle direction with a spring force.

  The geared motor 98 places the tip D shaft portion B into the center D hole of the cam 101. The cam 101 that is rotated by the geared motor 98 includes a fixed switch element operating piece 100 for a low thermal power position, a switch element operating piece 100 for a high thermal power position, and a needle pin 116 provided on the needle 111 that is movable in the vertical direction. A groove 117 is provided.

When the cam 101 is rotated, the needle 111 descends and the cam groove 117 finally comes into contact with the needle receiver 113 while adjusting the heating power. When the cam 101 is further rotated, the cam 1
01 depresses the needle receiver 113 against the spring D120 to avoid destruction of the electric drive device 18 and presses the needle 111 against the needle receiver 113 to ensure the accuracy of the minimum flow rate.

  FIG. 30 shows a block configuration of another electric drive device 18 and the flow rate control device 17. The electric drive device 18 includes a geared motor 98, a plurality of switch elements 99, a geared motor attachment frame 98-1 for attaching these components, and a cam 101. The flow control device 17 is configured so that a spring D120 is inserted into the needle receiving body 119 from above, and then a needle 111 having an O-ring 118 is inserted, and a spring press 121 having a spring E122 and a connecting pin 114 thereon. Is configured.

  The geared motor 98 places the tip D shaft portion 13 in the center D hole of the cam 101. The cam 101 rotated by the geared motor 98 has a function of transmitting the rotation of the geared motor 98 with the fixed switch element operating piece 100 for the low thermal power position, the switch element operating piece 100 for the high thermal power position, and the connecting pin 114 interposed therebetween, The needle receiving body 119 has a cam groove 117 that allows the connecting pin 114 to move in the vertical direction.

  As the cam 101 is rotated, the connecting pin 114 moves vertically up and down as the cam groove 117 rotates, and the spring E122 and the spring retainer 121 are pressed down to bring the needle 111 down into contact with the needle receiver 113. The cam 101 further rotates. As a result, the needle 111 abuts against a needle receiving portion (not shown) and does not lower any further. Therefore, the connecting pin 114 compresses the spring D122 to avoid the destruction of the electric drive device 18, and the needle 111 becomes the needle receiving 113. Ensure the accuracy of the minimum flow rate by pressure welding.

  Here, the relationship between the spring force of the spring E122 and the spring D120 is set so that the spring force of the spring D120 is weaker than that of the spring E122. The spring E122 has a role of pushing up the needle 111 when the push-down force of the spring D120 is weak. is doing.

  FIGS. 31 to 33 show an example in which the thermal power adjustment can be performed both electrically and manually.

  FIG. 31 shows an outline thereof. The electric drive unit 18 includes a geared motor 98 attached to a geared motor attachment frame 98-1, a cam 101 and an operating rod 123 movable by the geared motor 98, and a plurality of switch elements provided on the cam 101. It is composed of a plurality of switch elements 99 that perform ON-OFF operation by the operating piece 100.

  On the other hand, the thermal power adjusting lever 10 has an operating rod hole 10A through which the operating rod 123 passes, and the needle pin 116 is sandwiched by the sandwiching portion 10-1 from the fulcrum P portion of the thermal power adjusting lever 10, and the thermal power adjusting lever 10 is By rotating, the needle pin 116 is rotated, and the needle 111 is movable in the vertical direction with respect to the needle receiver 113 to control the flow rate.

  The flow rate control device 17 for controlling the flow rate by operating the thermal power adjusting lever 10 is not particularly limited as long as it adjusts the gas amount in addition to the specific mechanisms described in the previous embodiments. Absent.

  FIG. 32 shows the relationship between the operating rod 123 of the electric drive unit 18 and the thermal power adjusting lever 10. Even if the movable range W of the thermal power adjusting lever 10 is moved fully to the left and right, the operating rod 123 moves to point A (the central stop position). ), The shape of the operation hole 10A is set so as to be in the operation hole 10A of the thermal power adjustment lever 10 and not to contact the thermal power adjustment lever 10 to secure the gaps W1 and W2.

In this state, when the operating rod 123 is moved and moved from point A (central stop position) to point B (weak heating power position), the heating power adjustment lever 10 is moved in contact with the end surface of the operating rod hole 10A of the heating power adjustment lever 10. Can be moved. Similarly, when the operating rod 123 is moved from point A to point C (strong thermal power position), the thermal power adjustment lever 10 also moves.

  Here, in a state where the operating rod 123 is moved to the point C, it is necessary to move the operating rod 123 at the same time in order to manually move the heating power adjusting lever 10. There arises a problem that it is necessary or some means for separating the operating rod 123 and the electric drive unit is necessary.

  In the present invention, in order to solve such a problem, as shown in the flowcharts of FIGS. 10 and 11, when the operation rod 123 is moved to reach the target position, for example, when moving from point A to point C, point A A series of operations to return to is performed, so that it is always possible to manually adjust the thermal power.

  FIG. 33 shows a state when the operating rod 123 is moved. The horizontal axis represents the operating rod adjustment position (movement amount), and the vertical axis represents the amount of change in thermal power, the switch element 99-1 (SW1). And the switching state of 99-2 (SW2). At the low thermal power position, the thermal power is 400 Kcal / h, the switch element 99-1 (SW1) is ON, and the switch element 99-2 (SW2) is OFF. In the case of the central stop position, both the switch element 99-1 (SW1) and the switch element 99-2 (SW2) are in the ON state, and the thermal power is manually operated by the thermal power adjusting lever 10 at 400-4000 Kcal / h. It can be adjusted within the range. Further, at the position of strong thermal power, the thermal power is 4000 Kcal / h, the switch element 99-1 (SW1) is OFF, and the switch element 99-2 (SW2) is ON.

  Therefore, for example, when the electric drive device adjusts the heating power from the central stop position to the strong thermal power position and returns it to the central stop position, the geared motor 98 is rotated to the right from the central stop position (both SW1 and SW2 are ON) to reach the strong thermal power position. Is confirmed in the ON state of SW2, and after one end is stopped, the geared motor 98 is reversely rotated (counterclockwise), and it is confirmed that both the SW1 and SW2 are turned ON to return to the central stop position and stop. This makes it possible to adjust the thermal power by electric drive, and also to manually adjust the thermal power by returning to the central stop position.

  Note that the relationship between the operation rod 123 of the geared motor 98 and the operation rod hole 10A of the thermal power adjustment lever 10 is that, from the mounting state in the appliance, the thermal power adjustment lever 10 side is formed into the shape of the operation rod 123, and the electric drive part is provided with the hole. Providing is also promising as the second embodiment.

FIG. 34 is an example showing that the operating rod 123 has a resilient configuration.
The operation rod 123 is divided into a rotation drive unit 123-1, an elastic body part 123-2, and a tip part 123-3, and the elastic body part 123-2 is made of a spring material.

  In FIG. 32, when the operating rod 123 is moved to point B, for example, when the operating limit of the heating power adjusting lever 10 is reached and the operating rod 123 is movable, the operating rod 123 is utilized by utilizing the elasticity of the operating rod 123. This is a configuration in which a load is gradually applied to the electric drive device 18 by deforming. Therefore, it is possible to prevent a sudden load on the electric drive device 18 and the geared motor 98 from being destroyed. For example, when the flow rate control device 17 is a needle type, the needle 111 is pressed against the needle receiver 113 and the minimum flow rate of only the bypass nozzle is accurately set. It can be carried in.

FIG. 35, FIG. 36 (a) (b) (c) shows the other example which can adjust a thermal power by both electric power and manual operation. FIG. 35 shows an outline thereof. The electric drive unit 18 includes a geared motor 98 mounted on a geared motor mounting frame (not shown), and a cam 101 movable by the geared motor 98.
The operation piece 124 that sandwiches the heating power adjusting lever 10 with a specific width S and the plurality of switch elements 99 that perform the ON-OFF operation by the plurality of switch element operation pieces 100 provided on the cam 101 are configured. The thermal power adjusting lever 10 sandwiches the needle pin 116 from the portion of the fulcrum P of the thermal power adjusting lever 10 by the sandwiching portion 10-1, and when the lever 10 rotates, the needle pin 116 rotates to receive the needle 111 (not shown). The flow rate is controlled in the vertical direction.

  The flow rate control device 17 for controlling the flow rate by operating the thermal power adjusting lever 10 is not particularly limited as long as it adjusts the gas amount in addition to the specific mechanisms described in the previous embodiments. Absent.

  36 (a), 36 (b), and 36 (c) show the relationship between the operation piece 124 of the electric drive device 18 and the heating power adjustment lever 10, and the movable range W of the heating power adjustment lever 10 is fully moved to the left and right. In the case where the operation piece 124 is at the central stop position, the heating power adjustment lever 10 is within the specific width S of the operation piece 124, and has a specific width that secures the gaps W <b> 1 and W <b> 2 so as not to contact the heating power adjustment lever 10. Indicates the state.

  When the operation piece 124 is moved in the left direction in this state, the operation piece 124 comes into contact with the end face of the heating power adjustment lever 10, and the heating power adjustment lever 10 can be moved and moved to the strong heating power position. Similarly, when the operation piece 124 is moved in the right direction, the operation piece 124 comes into contact with the end face of the thermal power adjustment lever 10, and the thermal power adjustment lever 10 can be moved and moved to the weak thermal power position.

  However, in a state where the operation piece 124 is moved to the left and moved to the low thermal power position, manually moving the thermal power adjusting lever 10 requires the operation piece 124 to be moved at the same time, and the operation piece 124 is moved. There arises a problem that torque is required or some means for separating the operation piece 124 and the electric drive unit is necessary.

  In order to solve this problem, as described in the previous embodiment, in the present invention, when the operation piece 124 is moved to reach the target position (for example, when the operation piece 124 is moved from the central stop position to the low thermal power position), the central stop position is also reached. By making it return to, it is always possible to manually adjust the heat power.

  In addition, it is promising as a 2nd Example to provide the shape of an operation piece in the thermal-power adjustment lever 10 side from the installation conditions with respect to an instrument. Further, compared with the operation rod 123 method of FIG. 31, the thermal power adjusting lever 10 has an effect that it does not require special processing and can be attached to the current product having the thermal power lever 10.

  It should be noted that the amount of movement of the operation piece when the adjustment movable range of the thermal power adjustment lever 10 is moved by the operation piece 124, the amount of change in the thermal power, and the switching state of the switch elements 99-1 (SW1) and 99-2 (SW2). The contents are the same as in FIG. FIG. 37 is an example showing that the movable contact portion between the operation piece 124 and the heating power adjusting lever 10 has a resilient contact configuration. The operation piece 124 includes a rotation drive unit 124-1, an elastic body unit 124-. 2 and divided into a tip end portion 124-3, and the elastic body portion 124-2 was made of an elastic material.

  In FIG. 36, when the operation piece 操作 124 is moved to, for example, a weak heating power position, the movement limit point of the heating power adjustment lever 10 is reached and the operation piece 竿 124 is movable, the elasticity of the operation piece 124 is used. By deforming the operation piece 124, a load is gradually applied to the electric drive device 18. The effect is the same as that of FIG. 34, and description thereof is omitted.

  Although the thermal power adjustment lever 10 is moved by the operation piece 124 to adjust the thermal power, moving the needle pin 116 similarly is also promising as the second embodiment.

  Further, as a second embodiment, it is promising that the needle pin 116 is movable, and the operation piece 124 is a disk-shaped operation piece that is partly gear-shaped and the rotation transmission of the geared motor 98 is cut into a fan shape. is there.

  38, 39 (a), 39 (b), and 39 (c) show still another example in which the heating power can be adjusted both electrically and manually. FIG. 38 shows an outline thereof. The electric drive device 18 includes a geared motor 98 attached to a geared motor attachment frame 98-1, an electric drive gear 125 rotated by the geared motor 98, and a plurality of switch elements provided in the electric drive gear 125. An operating piece 100 is provided.

  The plurality of switch element operation pieces 100 are configured to turn on and off the plurality of switch elements 99 attached to the attachment frame 98-1 by rotating the electric drive gear 125, and the fulcrum of the electric drive gear 125 is The heating power adjusting lever 10 is configured on the same fulcrum.

  In order to move the thermal power adjustment lever 10 by the electric drive gear 125, the thermal power adjustment lever 10 is provided with a convex portion 126 such as a pin in the circumference of the electric drive gear 125, and the electric drive gear 125 is provided with the convex portion 126. Correspondingly, a circumferential hole 125A is provided.

  Further, the thermal power adjusting lever 10 sandwiches the needle pin 116 from the portion of the fulcrum P of the thermal power adjusting lever 10 by the sandwiching portion 10-1, and when the thermal power adjusting lever 10 rotates, the needle pin 116 rotates and the needle 111 is moved. It is configured to move in the vertical direction with respect to a needle receiver (not shown) and control the flow rate.

  The flow rate control device 17 for controlling the flow rate by operating the thermal power adjusting lever 10 is not particularly limited as long as it adjusts the gas amount in addition to the specific mechanisms described in the previous embodiments. Absent.

  39 (a), 39 (b), and 39 (c) show the operational relationship between the electric drive gear 125 of the electric drive device 18 and the thermal power adjustment lever 10, and the thermal power adjustment lever 10 is provided with a convex portion 126, and the electric drive gear is shown. 125 is provided with a hole 125 </ b> A at a position opposite to the convex portion 126 of the heating power adjusting lever 10.

  The notch width of the hole 125A is set to a range in which the projection 126 does not contact the end of the hole 125A by moving the thermal power adjusting lever 10 by a movable rotation angle α °. Accordingly, in this state, the thermal power adjusting lever 10 can be operated regardless of the electric drive gear 125, and the stop state of the electric drive device 18 at this time is set as the central stop position.

  Here, when the electric drive device 18 is driven and the electric drive gear 125 is rotated clockwise from the state where the thermal power adjustment lever 10 is in the center, the convex portion 126 of the thermal power adjustment lever 10 contacts the right end portion of the hole 125A of the electric drive gear 125. It will move in accordance with the electric drive gear rotation in contact (low heat power position).

  Similarly, when the electric drive device 18 is driven and the electric drive gear 125 is rotated counterclockwise from the state where the thermal power adjustment lever 10 is in the center, the convex portion 126 of the thermal power adjustment lever 10 is notched to the left end portion of the hole 125A of the electric drive gear 125. And move according to the rotation of the electric drive gear 125 (strong thermal power position).

However, in the state where the electric drive gear 125 is rotated to the left and moved to the high thermal power position,
To manually move the thermal power adjustment lever 10 requires that the electric drive gear 125 also be rotated at the same time, and a torque for rotating the electric drive gear 125 is required, or some means for separating the electric drive gear 125 from the electric drive unit is required. A problem arises.

  In order to solve these problems, as described in the previous embodiment, in the present invention, when the electric drive gear 125 is moved to reach the target position (for example, moved from the central stop position to the low thermal power position), The configuration is such that the heating power can always be adjusted manually by returning to the stop position.

  It should be noted that the rotational movement amount when the adjustment movable range of the thermal power adjustment lever 10 is rotationally moved by the electric drive gear 125, the variation amount of the thermal power, and the switching state of the switch elements 99-1 (SW1) and 99-2 (SW2). The contents of are the same as those in FIG.

  According to the method of this embodiment, there is an effect that the transmission efficiency between the gears is good, the transmission efficiency is good, and the torque of the electric drive device 18 is minimized as compared with other transmission methods.

  FIG. 40 shows still another example in which the heating power can be adjusted both electrically and manually. The electric drive unit 18 includes a geared motor 98 mounted on a geared motor mounting frame (not shown), a cam 101 movable by the geared motor 98, The operation rod 126 and a plurality of switch element operation pieces 100 provided on the cam 101 are configured by a plurality of switch elements 99 that perform an ON-OFF operation.

The needle pin 116 is rotated, and the needle (not shown) is moved in the vertical direction with respect to the needle receiver (not shown) to control the flow rate.

  The flow rate control device 17 for controlling the flow rate by operating the thermal power adjusting lever 10 is not particularly limited as long as it adjusts the gas amount in addition to the specific mechanisms described in the previous embodiments. Absent. Detailed description is omitted because it has a similar configuration to FIGS.

  According to the above configuration, since the heating power adjustment lever 10 and the electric drive device 18 are connected by the operation rod 126, even if a slight error occurs in the mounting position, it can be expected to move without any problem.

  FIG. 41 shows still another example in which the heating power can be adjusted both electrically and manually. The electric drive unit 18 is a geared motor 98 attached to a geared motor attachment frame 98-1, and a pinion 128 having a pinion rack configuration movable by the geared motor 98. The plurality of switch element operation pieces 100 provided on the pinion 128 and the plurality of switch elements 99 attached to the geared motor attachment frame 98-1 according to the drive of the binion 128 are turned on and off.

The needle pin 116 is pinched by the pinching portion 10-1 from the portion, and the needle pin 116 is rotated by rotating the heating power adjusting lever 10, and the needle is moved in a direction perpendicular to the needle receiver to control the flow rate.

The flow rate control device 17 for controlling the flow rate by operating the thermal power adjusting lever 10 is not particularly limited as long as it adjusts the gas amount in addition to the specific mechanisms described in the previous embodiments. Absent. This method can be expected to be installed when the installation position of the driving device 18 in the appliance is not so much in the vertical direction of the thermal power control lever 10 and there is a margin in the lateral direction.

  FIGS. 42 to 43 are explanatory diagrams for revising the method of detecting the central stop position by the two switch elements 99 shown in FIG. 33 and detecting the central stop position by using three switch elements 99.

  FIG. 42 is a perspective view showing a means for providing a central stop position. The cam 101 is provided with switch element operating pieces 100A, 100B, 100A + B + C, a central stop position switch element operating piece 100C, and the switch element operating piece 100C has a low heating power. It is characterized by being continuous from the position to the middle heating power position.

  FIG. 43 shows the state when the cam 101 is used. The rotation angle of the cam 101 on the horizontal axis includes a weak heating power position, a center stop position, and a strong heating power position, and the vertical axis indicates the heating power of the cam 101 at that time. The change amount and the ON / OFF state of the switch element 99-1 (SW1), the switch element 99-2 (SW2), and the switch element 99-3 (SW3) are shown.

  44 to 46 show a thermal power adjusting lever configuration that can be operated by both electric drive and manual operation, and shows an example in which medium thermal power can be selected in addition to the strong and weak thermal power positions that can be selected by electric drive. It is.

  In FIG. 44, reference numeral 124 denotes an operation piece for movably transmitting the heating power adjustment lever by the electric drive device 18; the switch cam 101 fixed to the operation piece 124; the switch element operation pieces 100A, 100B, 100A + B provided on the switch cam 101; 100C1 and 100C2 and a plurality of switch elements 99.

  FIG. 45 is a diagram for explaining the operation of the operation piece 124 and the thermal power adjustment lever 10. FIG. 45A shows that the operation piece 124 is located at the central stop position and the thermal power adjustment lever 10 is movable in the range of weak to strong thermal power positions. It is illustrated. (B) In the case where the thermal power adjustment lever 10 which is in the low thermal power position by electric drive is moved to the medium low thermal power position, and (c) in FIG. The movement of the operation piece 124 in the case of moving to the position is shown. When the thermal power adjustment lever 10 that was in the low thermal power position of (b) is moved to the medium to low thermal power position, the operation piece 124 is moved to the strong thermal power position side. This indicates that the heating power adjustment lever 10 does not move to the middle heating power position even if it is moved from the position to the middle heating power.

  FIG. 46 shows a state when the operation piece 124 is moved. The horizontal axis represents the rotation angle of the switch cam 101 (operation piece movement amount), and the vertical axis represents the thermal power change amount and the switch element 99-. The switching states of 1 (SW1), 99-2 (SW2) and 99-3 (SW3) are shown.

  The switch element 99-1 corresponds to the switch element operating pieces 100A, 100A + B, the switch element 99-2 corresponds to the switch element operating pieces 100B, 100A + B, and the switch element 99-3 corresponds to the switch element operating pieces 100C1, 100C2. .

  When the thermal power position is on the horizontal axis, the thermal power is 400 Kcal / h, the switch element 99-1 (SW1) is ON, the switch element 99-2 (SW2) is OFF, and the central stop position In this case, the switch elements 99-1 (SW1) and 99-2 (SW2) are both in the ON state, and the thermal power can be manually operated by arbitrarily operating the thermal power adjustment lever 10. Adjustment at this time is possible in the range of 400-4000 Kcal / h.

  In the case of the strong thermal power position, the thermal power is 4000 Kcal / h, indicating that the switch element 99-1 (SW1) is OFF and the switch element 99-2 (SW2) is ON.

  The above has already been described with reference to FIG. 33. Unlike the case of the strong and weak thermal power position, the provision of the intermediate thermal power position is related to the drive control of the electric drive unit 18, and the weak thermal power starts from the central stop position in the figure. In the case where the medium thermal power position is aligned with the position direction, the rotation direction of the electric drive device 18 is rotated counterclockwise, and the ON position (switch element operating piece 100C1 position) of the switch element 99-3 (SW3) becomes the medium thermal power position.

  Similarly, when the thermal power position is aligned with the strong thermal power position direction, the rotational direction of the electric drive device 18 is rotated to the right, and the ON position (switch element operating piece 100C2 position) of the switch element 99-3 (SW3) becomes the medium thermal power position.

  Therefore, when adjusting to the middle heating power position, it is necessary to select the rotation direction according to the current position of the heating power adjustment lever 10, but since the heating power adjustment lever 10 has no means for determining the position, the heating power adjustment lever 10 is temporarily set to a strong or low heat. It is moved to the force position and the position is clarified and moved to the medium heating power position, or it is determined from the temperature of the pan bottom temperature sensor 2 and the cooking mode condition, the current position is estimated, and the drive direction of the electric drive device 18 is determined. There is a need.

  Further, by making the switch element operating pieces 100, 100C1, and 100C2 for determining the medium heating power position movable, the medium heating power can be freely set (a method of moving is shown in FIG. 5 and FIG. 27 as a reference example). .

  FIG. 47 is an example in which the thermal power adjustment lever 10 is provided with a medium thermal power position setting switch. The switch element operating piece 100C for the medium thermal power position shown in FIG.

  Since the switch element operating piece 100C is located on the heating power adjusting lever 10, the heating power adjusting lever 10 is temporarily moved to the strong or weak heating power position and the position is clarified and moved to the medium heating power position, or the temperature of the pan bottom temperature sensor 2 is set. Thus, it is not necessary to perform complicated processing such as determining from the cooking mode conditions, estimating the current position, and determining the driving direction of the electric drive device 18.

Further, since the switch element operating piece 100C for operating the switch element 99-3 (SW3) is provided in the thermal power adjusting lever 10, compared to the switch cam 101 system in which the thermal power adjusting lever 10 in FIG. Medium thermal power has a structure that makes it easier to obtain a constant value.

  FIG. 48 shows an example in which the position of the medium heating power is varied, and the switch element operating piece 100C for operating the switch element 99-3 (SW3) is provided on the cam B101-1 attached to the heating power adjusting lever 10, and the switch element operating piece 100C is provided. In order to change the setting position of the cam, the cam B 101-1 is provided with an adjustment hole 110, set to a target position, and fixed to the fixing screw hole 109 of the heating power adjusting lever 10 with the fixing screw 10 B, thereby increasing the medium heating power. The position can be changed.

  By making the position of the medium heat power variable, for example, the medium heat power of the non-burning function can be set to an optimum heat power of about 1000 Kcal / h with the heat power that can not be spilled after boiling, and can be set to about 1000 Kcal / h. Can be set to a heating power of about 2300 Kcal / h when fried tempura with a general stove.

  Therefore, if the purpose of use of the stove is limited in advance and is characterized by non-burning, the medium heating power is set to about 1000 Kcal / h with the non-burning prevention function. In addition, when proactively appealing the functional characteristics, the position of 1000 Kcal / h differs depending on each gas type as shown in FIG. 12 as an example. Therefore, the medium thermal power position is finely adjusted at the time of shipment from the factory according to each gas type. It can be secured.

  FIG. 49 shows an example in which the user can arbitrarily set a medium heating power position that varies depending on the cooking contents. Basically, a medium heating power setting lever 130 is provided on the cam B101-1 shown in FIG. The heating power adjusting lever 10 is fixed by a fixing pin 131 so as to be rotatable.

  The medium heating power setting lever 130 is operable on the operation panel surface together with the heating power adjusting lever 10, and the user can set the medium heating power corresponding to the cooking mode according to his / her preference.

  FIG. 50 shows an example in which a plurality of medium heating power setting switches are provided in the heating power adjusting lever 10 shown in FIG. 48 (the number of switches is one in FIG. 48). A plurality of light transmitting holes 133 of the light emitting part of the switch 132 are provided, and the amount of movement is counted by counting the number of light transmitted through the light receiving part, thereby making it possible to determine the position of the medium heating power.

  For example, when cooking boiled food, it is generally heated with high heat until boiling, and after boiling, the medium heat power is adjusted according to the user's many years of experience depending on the food, the contents of cooking, and the size of the pan. Set with lever 10. Therefore, the medium heating power is not constant and changes every time.

  When the heating control means 24 confirms whether or not it is in a burned state during boiling with this medium heating power, the heating power is once weakened to the weak heating power position for confirmation. As a result of confirmation, when returning to the original thermal power position without being burned, as a means to determine the original thermal power position, the medium thermal power is shifted to the weak thermal power position, but at that time, only the numerical value counted by the light receiving unit is rotated backward. By this, it becomes possible to return to the original medium-fired power making use of the many years of experience set by the user.

  Although the above shows one embodiment using a photoelectric switch, the second embodiment in which the current position can be discriminated by using a combination of the shape of the cam 101 and the switch element 99 or an encoder, has the same effect. Can be demonstrated. In addition, when an encoder is used, it is possible to know the user's thermal power adjustment process.

  FIGS. 51 to 53 are perspective views showing an embodiment in the case where the heating power adjustment is performed by using the common flow control device 17 for the electric drive device 18 and the manual button 134.

  FIG. 51 shows an embodiment in which the heating power adjusting lever 10 is rotationally driven by a button 134. In the figure, the tip of the thermal power adjusting lever 10 is formed into a gear shape 135, the gear 134A is cut off on the thermal power adjusting button 134, and the thermal power adjusting lever 10 is driven by rotating the button 34. Since the operation method has been described above, it will be omitted. In the case of the thermal power control lever 10 method, it is necessary to regulate the movable range of the thermal power control lever 10 on the operation panel (not shown) by making it a slit shape. It is only necessary to provide a hole, so that an infant does not put a hand into the slit and the appearance can be different from the lever system.

  FIG. 52 is an example in which the thermal power adjustment button 136 has a double structure, the inner button 137 is an ignition button, and the outer button 136 is a thermal power adjustment. The tip of the thermal power adjustment lever 10 has a gear shape 138, and the gear 136A is cut off and connected to the outer thermal power adjustment button 136. Since the operation method has been described above, it will be omitted.

  53, the ignition button and the thermal power adjustment button are configured by the same component 139, the ignition / extinguishing operation is a push operation, the thermal power adjustment is a turning operation, and the flow rate control mechanism by the thermal power adjustment button 139 and the heating control are performed. It is a figure which shows an example of the structure shared with the flow control device 17 of the means 24. FIG.

  The button 139 pushes the valve operating rod 142A of the cock body 142 to open a gas passage when the button 139 is inserted and pushed into the shaft 141 from the case 140 having a built-in push-push locking mechanism. Whether the button 136 is popped out or pushed in this state differs depending on the configuration of the lock mechanism in the lock mechanism case 140, but is not a necessary item of the present invention and will not be described in detail.

  The gear portion 143 of the button 139 meshes with the long electric drive gear B144 of the flow control device 17, and when the button 139 is operated, the long gear shape is slid to maintain the connection. When the electric drive gear B144 is rotated, the needle 111 configured to transmit the rotation movably in the vertical direction is rotated.

  When this needle 111 is rotated, it is inserted into a needle body part 145 having a groove part that moves in the vertical direction. Since the needle mechanism has been described above, a description thereof will be omitted.

  The electric drive device 18 includes a geared motor 98, an electric drive gear 125 provided on the same fulcrum of the electric drive gear B144, and a plurality of switch elements 99 driven by a plurality of switch element operating pieces provided in the electric drive gear 125. It is said. In addition, about the movable state of the electric drive gear 125 and the electric drive gear B144, since the similar structure is described in FIG. 39, description is abbreviate | omitted.

  Further, the flow rate control device 17 for controlling the flow rate by operating the electric drive gear B144 is not particularly limited as long as it adjusts the gas amount in addition to the specific mechanisms described in the previous embodiments. Absent.
