Therefore, the flame gradually increases compared to the conventional specification in which the solenoid valve is turned on to rapidly change from weak combustion to strong combustion. Even when the hand is brought close to the vicinity, danger prediction can be made while knowing the state of the flame, and sleeve fire can be prevented. In addition, it is possible to provide an appliance which can be used with a sense of security by eliminating primary red-flame combustion caused by a shortage of air which is generated when the flame suddenly changes. In addition, since electric power used for electric driving is only for driving, it can be used with a dry battery in a power saving configuration and does not require 100 V, so that it can be used in ordinary households without resistance.

Further, the gas cooker of the present invention has a temperature setting means, and the control circuit drives the electric drive device by comparing the output from the temperature detecting means with the temperature set by the temperature setting means. Yes, automatic temperature control is performed by the temperature control function, and a proper heat power suitable for cooking can be obtained.

[0010] In the gas cooker according to the present invention, the control circuit comprises:
A cooking mode determining means for determining a cooking mode and setting a control temperature according to the determined cooking mode; and outputting a predetermined output by comparing an output from the temperature detecting means with the control temperature set by the cooking mode determining means. Operation control means, and is configured to drive the electric drive device based on an output from the operation control means, so that appropriate heating power in accordance with various cooking modes can be controlled by the heating control means. Correction of thermal power adjustment error can be done.

Further, the gas cooker of the present invention has a temperature setting means, and the control circuit determines a cooking mode and sets a control temperature according to the determined cooking mode, and a temperature detection means. Operation control means for comparing the output from the means with the control temperature set by the cooking mode determination means or the temperature set by the temperature setting means to output a predetermined output, and the output from the operation control means It is configured to drive the electric drive device based on the electric drive.

According to this configuration, it is also possible to control the appropriate heating power according to the various cooking modes by the heating control means.
In addition to correcting the user's thermal power adjustment error, automatic temperature control is performed by the temperature control function, and an appropriate thermal power suitable for cooking can be obtained.

For example, in the case of a stewed dish, if the user inadvertently executes cooking with high heat even after boiling, if only the bottom of the pan is scorched, the heat control means can be used to switch to low heat or a frying pan. If the cooking using is performed with an unnecessarily large high heat, the oil overheat prevention device of the heating control means is operated, and it is possible to automatically lower the heat to a low heat before automatically extinguishing the fire and to see the situation.

Further, in the gas cooker according to the present invention, the control circuit includes drive judging means for driving the electric driving device, and the driving judging means is upstream of the flow rate adjusting device when the heating means or the electric driving device has an abnormality. The safety valve provided on the upstream side is closed, and when an abnormality occurs, the safety valve provided on the upstream side of the flow control device is closed, which is safe.

Further, in the gas cooking device according to the present invention, the control circuit is configured to drive the flow rate control device to at least the high heating power position, the low heating power position, and the medium heating power position via the electric driving device, and to control the temperature. During operation, when the temperature of the temperature detecting means is higher than the set temperature, the medium is moved to the medium heating power position or the low heating power position, and when the temperature of the temperature detecting means becomes lower than the set temperature by burning with low heating power, the high heat is applied. It is configured to be movable to a force position or a medium heat position.

According to this configuration, since the position of the medium heating power is provided, an effect of minimizing the driving of the electric driving device can be expected. Reducing the number of times of electric driving reduces the failure of the electric driving device, prolongs the life, saves power, and extends the life of the battery in the case of a dry battery power supply. In addition, it is possible to control the appropriate heating power according to the various cooking modes by the heating control means, and it is also possible to correct the user's adjustment of the heating power. For example,
If automatic temperature control is performed without medium heat with the temperature control function, it is necessary to supply a constant calorie at the ratio of maximum heat to minimum heat, but if medium heat is incorporated, the number of times of combustion switching is extremely small, The appropriate thermal power will be obtained.

In addition, in the case of a stewed dish, if the user inadvertently performs cooking with high heat even after boiling, only the bottom of the pot is scorched and switched to low heat with heating control means. Do not sneak back. In this case, the heating control means returns to the medium heat power. Similarly, if cooking using a frying pan is performed at an unnecessarily large high heat, the oil overheat prevention device of the heating control means will be activated. Returning to the above becomes a repetitive operation, giving the user discomfort. In this case, the heating control means can return to medium heat.

Further, in the gas cooking device according to the present invention, the control circuit is configured to drive the flow rate control device to at least the high heating power position, the low heating power position, and the medium heating power position via the electric driving device. At the time of operating the temperature control function, the temperature of the temperature detecting means becomes higher than the set temperature, and the heating control means burns with low heating power, and when the temperature of the temperature detecting means becomes lower than the set temperature, it is moved to the medium heating power position. There is a configuration.

According to this configuration, when the temperature control function for preventing non-sticking is in operation, when the combustion is performed at a low heating power by electric drive, the temperature is detected due to the shortage of the heating power, and when the temperature of the outage becomes lower than the set temperature, the medium heating position is set. Return and automatically set the heating power suitable for cooking.

Further, in the gas cooking device of the present invention, the control circuit is configured to drive the flow control device to at least the high heating power position, the low heating power position, and the medium heating power position via the electric driving device, and the operation control means. When the temperature control function for preventing oil overheating is operating, the temperature of the temperature detecting means becomes higher than the set temperature, and the heating control means burns with low heating power, and when the temperature of the temperature detecting means becomes lower than the set temperature, It is configured to be movable to the heating position.

According to this configuration, the temperature of the temperature detecting means is higher than the set temperature during operation of the temperature control function for preventing oil overheating.
When the temperature of the temperature detecting means is low due to insufficient heating when burning with weak heating by electric drive, return to the medium heating position,
The heating power suitable for cooking can be set automatically.

Further, the gas cooker according to the present invention comprises a heating means for heating the pot, a heating control means for controlling the heating means, a temperature detecting means for detecting the temperature of the pot, and a heating power adjusting lever for manually adjusting the heating power. And the heating control means includes an electric driving device, and a flow control device that is driven by the electric driving device and the heating power adjustment lever to adjust the heating power.

According to this configuration, since the flow control mechanism performed by the heating power control lever is also used as the flow control device of the heating control means, the heating power control lever can be driven by two methods, manual and electric. The adjusting device can be constituted by one. Therefore, for example, when the flow rate adjustment unit is configured with two pieces, if the weak flow rate is set by the manual heating power adjustment and the weak flow rate is also set by the electric drive, the flow rate pressure loss occurs at the minimum flow rate, and the flow rate is smaller than the required amount. As a result, when the supply gas pressure is low, a stable flame cannot be secured and a fire may occur. In addition, the minimum flow rate may be set larger in anticipation of this state, and the minimum calorie required for cooking, for example, 400 Kcal
/ h may not be available. However, these factors can be eliminated by configuring the flow rate control unit by one. In addition, naturally, the number of components is reduced, and there is an effect that it can be provided at low cost.

In the gas cooker according to the present invention, the flow rate adjusting means is configured to gradually change from weak to strong to notify the user of the increase in the flame. It can evoke that the flame gets bigger.

In the gas cooker according to the present invention, the heating control means determines the cooking mode and sets a control temperature in accordance with the determined cooking mode, and determines whether or not the output from the temperature detecting means is the control temperature. A control circuit for operating the electric driving device in response to the electric power, and the control circuit drives the heating power adjusting lever through the electric driving device based on the output from the temperature detecting means to perform the heating power adjustment, and also changes the heating power from the low heating power to the high heating power. Is configured to change slowly.

With this configuration, the appropriate heating power according to the various cooking modes can be controlled by the heating control means, and correction of the heating power error by the user can be corrected.

Further, the gas cooker of the present invention has a temperature setting means, and the heating control means sets the temperature by the temperature setting means or determines a cooking mode to set the control temperature and outputs the output from the temperature detection means. A control circuit for operating the electric drive device according to the control temperature or not, wherein the control circuit drives the heat control lever via the electric drive device based on the output from the temperature detecting means to perform the heat control. At the same time, it is configured to gradually change from low heating power to high heating power.

According to this configuration, it is also possible to control an appropriate heating power according to various cooking modes by the heating control means.
In addition to correcting the user's thermal power adjustment error, automatic temperature control is performed by the temperature control function, and an appropriate thermal power suitable for cooking can be obtained.

For example, in the case of a stewed dish, when the user carelessly executes cooking with high heat even after boiling, if only the bottom of the pan is scorched, the heat control means can be used to switch to low heat, or a frying pan. If the cooking using is performed with an unnecessarily large high heat, the oil overheat prevention device of the heating control means is operated, and it is possible to automatically lower the heat to a low heat before automatically extinguishing the fire and to see the situation.

Further, in the gas cooker of the present invention, the control circuit includes a drive judging means for driving the electric driving device, and the driving judging means is located on the upstream side of the flow rate adjusting device when there is an abnormality in the heating means or the electric driving device. The safety valve provided on the upstream side is closed, and when an abnormality occurs, the safety valve provided on the upstream side of the flow control device is closed, which is safe.

Further, the gas cooker according to the present invention is configured such that the flow control device driven by the heat control lever or the electric drive device is driven at least to the high heat position, the low heat position and the medium heat position, and the temperature is controlled. During function operation,
If the temperature of the temperature detection means is higher than the set temperature, the medium heat position, or move to the low heat power position, and when the temperature of the temperature detection means is lower than the set temperature by burning with low heat,
It is configured to be movable to a high heating power position or a medium heating power position.

According to this configuration, since the intermediate heating position is provided, the effect of minimizing the driving of the electric driving device can be expected. Reducing the number of times of electric driving reduces the failure of the electric driving device, prolongs the life, saves power, and extends the life of the battery in the case of a dry battery power supply. In addition, it is possible to control the appropriate heating power according to the various cooking modes by the heating control means, and it is also possible to correct the user's adjustment of the heating power. For example,
If automatic temperature control is performed without medium heat with the temperature control function, it is necessary to supply a constant calorie at the ratio of maximum heat to minimum heat, but if medium heat is incorporated, the number of times of combustion switching is extremely small, The appropriate thermal power will be obtained. In addition, in the case of stewed cooking, if the user carelessly executes cooking with high heat even after boiling, only the bottom of the pan is scorched,
The heating control means switches to low heating power, and it does not endure to return to the original heating power after the temperature decreases over time. In this case, the heating control means returns to the medium heat power. Similarly, if cooking using a frying pan is performed at an unnecessarily large high heat, the oil overheat prevention device of the heating control means will be activated. Returning to the above becomes a repetitive operation, giving the user discomfort. In this case, the heating control means can return to medium heat.

The gas cooker according to the present invention is configured such that the flow control device driven by the heating power adjusting lever or the electric driving device is driven to at least the high heating power position, the low heating power position, and the medium heating power position, and The control lever is provided with a center stop position setting switch. With this configuration, the accuracy of the flow rate of the medium thermal power is improved, and a high quality feeling that the medium thermal power is always a constant thermal power can be provided to the user.

In the gas cooker of the present invention, when the flow control device is moved by the electric drive device, the heating power adjusting lever is also displayed as the automatic heating power setting position,
When the position is set to the low heating power position by the electric driving device, the heating power adjustment lever also moves to the low heating power position in conjunction with the operation, and the user can easily determine that the fuel is burning with the low heating power.

In the gas cooker according to the present invention, the electric drive unit is linked with the heat control lever with a predetermined play, and the control circuit drives the heat control lever to the high or low heat position, and then stops at the center. By returning to the position, the heating power adjustment lever can be manually driven between a high heating power and a low heating power.

According to this configuration, at the time of manual operation, the driving portion of the electric driving device is not in contact with the heating power adjusting lever.
It can be operated with the light moving force of a normal firepower control lever without electric drive. Also, an old-type thermal power control lever without an electric drive can be used as it is.

In the gas cooker according to the present invention, the electric drive unit is provided with a drive linking means, and the thermal power control lever is provided with a linking section which is linked with the drive linking means. The thermal power control lever and the electric drive device are linked with a predetermined play as a linkage configuration having an interval of. With this configuration, for example, the drive linking means and the linking section can be linked by a hole type, so that there is no need to perform special fixing, and it is easy to connect even in a limited narrow space, and there is a degree of freedom in the mounting position. It can be easily attached to existing products.

Further, in the gas cooking device of the present invention, one of the drive linking means and the linking portion is elastically deformable so as to buffer an overload when the drive linking means and the linking portion are engaged. Yes, when the heating power control lever is moved by electric drive and reaches the movable limit, a sudden overload is not applied to the electric drive device, so that the deformation of the linked components can be prevented and the electric drive device is damaged. For example, it is possible to reduce factors such as failures and improve reliability. When the heating power adjusting mechanism is a needle type, the minimum flow rate can be properly secured by pressing the needle against the needle receiving portion.

In the gas cooker according to the present invention, the electric drive unit has a central stop position, and the electric drive unit or the heat control lever has a strong heat position and a low heat position. The fulcrum of the gear for electric drive is positioned on the fulcrum of the above, and the gear is electrically driven. When the electric drive device is in the center stop state, the gear for electric drive and the heating power adjustment lever The movable range (movable angle) of the adjusting lever does not transmit torque to the electric drive gear, but transmits torque to the thermal power adjusting lever when the electric drive gear is rotated.

According to this configuration, at the time of manual operation, since the electric drive gear is not in contact with the heating power adjustment lever, the operation can be performed with a small movable force of the ordinary heating power adjustment lever without electric driving. Further, since the electric drive gear is located on the fulcrum of the thermal power adjustment lever, the electric drive torque can be transmitted directly, and the power consumption for the electric drive can be reduced.

Further, in the gas cooking device of the present invention, the control circuit uses two switching elements which are turned on / off by the operation of the electric driving device, and is capable of discriminating the positions of the strong, weak heating position and the central stop position. is there.

According to this configuration, the position of the strong, low heating power position and the central stop position of the electric driving device can be determined with a minimum use of two switching elements, and the electric driving device can be reduced in size and controlled. The use of signal lines in the circuit is reduced, and the wiring processing can be reduced, and the probability of failure can be reduced accordingly.

Further, in the gas cooking device of the present invention, the control circuit uses three switching elements which are turned on / off by the operation of the electric driving device, and is used for the high and low heating power positions, the central stop position, and the central and high heating power positions. The position of the intermediate state between the middle, the center and the low heating power position can be determined.

With this configuration, it is possible to determine the position of the strong, low heating power position and the central stop position of the electric drive device by using three switching elements, and the current position can always be determined by the control circuit. Therefore, when returning to the central stop position when the power is cut off during the movement and the power is re-applied thereafter, an operation to immediately return from the current stop position is possible. In the case of the two switching element type, the position cannot be determined, and a complicated operation of operating in either the strong or weak heating power position position to move the current position to the target position after the determination is required. Usability improves without anything.

Further, in the gas cooking device of the present invention, when the control circuit drives the electric driving device to the high heating power position or the low heating power position, and when the abnormality does not reach the target position within a predetermined time,
It is configured to include drive determination means for returning the electric drive device to the center stop position.

According to this configuration, when the electric driving device is driven to the high heating power position or the low heating power position, when the target position is not reached within a predetermined time, the electric driving device is returned to the central stop position. Even if the heating power cannot be adjusted by the electric driving device, the manual heating power can be adjusted, and the usability is improved. (For example, if the electric drive device stops at the middle point while moving, if you try to manually operate the thermal power adjustment lever,
It is movable up to the position where the electric driving device is stopped, but the electric driving device does not move to the position after that, so that it is impossible to adjust the heating power manually and it is not easy to use. The heat power adjustment lever is provided with a multi-step or stepless position detector, and the position of the heat power adjustment lever can be detected based on the output from the position detector.

According to this configuration, the heating power can be adjusted in multiple steps or steplessly by the position signal of the position detector of the heating power adjusting lever. It is possible to automatically set the fired power.

Further, in the gas cooking device of the present invention, when the temperature control function for preventing non-sticking is in operation, the temperature of the temperature detecting means is higher than the set temperature, and when the combustion is performed with a weak heating power by electric drive, the temperature of the temperature detecting means is insufficient due to insufficient heating power. When the temperature becomes low, the apparatus has a function of returning to the original heating power arbitrarily set by the user by electric drive.

According to this configuration, when the temperature control function for preventing non-sticking is in operation, the temperature of the temperature detecting means is higher than the set temperature, and when the combustion is performed with a weak heating power by electric drive, the temperature of the temperature detecting means becomes insufficient due to insufficient heating power. When the temperature becomes lower, by returning to the medium heat power position set by the user, unnecessary automatic fire extinguishing can be prevented, and an easy-to-use non-stick stove can be provided.

Further, in the gas cooking device of the present invention, when the temperature control function for preventing oil overheating of the heating control means is operated, the temperature of the temperature detection means is higher than the set temperature, and when the combustion is performed with a weak heating power by electric driving, the heating power is insufficient. When the temperature of the temperature detecting means becomes lower than the set temperature, the apparatus has a function of returning to the original heating power arbitrarily set by the user by electric drive.

According to this configuration, during operation of the temperature control function for preventing overheating, the temperature of the temperature detecting means is higher than the set temperature, and the temperature of the temperature detecting means is low due to insufficient heating power when burning with weak heating power by electric drive. At this time, by returning to the medium heat power position set by the user, unnecessary automatic fire extinguishing can be prevented, and a stove with overheating prevention that is easy to use can be provided.

Further, the gas cooker of the present invention has a heating means for heating the pan, a heating control means for controlling the heating means, a temperature detecting means for detecting the temperature of the pan, and an ignition button for performing an ignition / extinguishing operation. A heating power control button for manually adjusting the heating power, and the heating control means is provided with an electric driving device and a flow control device driven by the heating power adjustment button to perform the heating power adjustment.

According to this structure, the structure can be simplified by using the flow rate control mechanism using the heat power adjustment button and the flow rate control device of the heating control means, and the heat power adjustment method is a button. Unlike the adjustment lever, there is no need to secure a space for sliding, and the device can be compactly formed. In addition, since it can be driven by two methods, manual and electric, and only one flow control device may be used, for example, in the case of two flow control devices, a weak flow is set by manual thermal power adjustment, and a weak flow is also set by electric drive. If set, the minimum flow rate will cause a flow pressure drop, the flow rate will be less than required,
As a result, when the supply gas pressure is low, a stable flame cannot be secured and a fire may occur. In addition, the minimum flow rate may be set larger in anticipation of this state, and the minimum calorie required for cooking, for example, 400 Kcal / h may not be obtained.
However, these factors can be eliminated by using a single flow control device. In addition, naturally, the number of components is reduced, and it can be provided at low cost.

Further, in the gas cooking device of the present invention, when the flow rate control mechanism is moved by the heating control means, the heating power adjustment button is moved to display the same as the automatic heating power setting position display. If you change it,
The heating power adjustment button also moves to the changed heating power position in conjunction with the operation, and the user can easily determine the current heating power.

The gas cooker of the present invention has a button divided into two parts, an inner periphery and an outer periphery, with an ignition / extinguishing button on the inside and a heating power adjustment button on the outside.

According to this configuration, the area of the operation panel can be minimized as compared with the case of the thermal power control lever. Also, the design can be made compact.

Further, in the gas cooker of the present invention, the ignition button and the heating power adjustment button are the same parts, and the ignition / extinguishing operation is a push operation and the heating power adjustment is a turning operation.

According to this configuration, the electric drive for ignition / extinguishing / control of heating power can be provided by one button, and the operation panel can be provided with versatility and the area of the operation panel can be minimized. Also, the design can be made compact.

Further, in the gas cooking device of the present invention, the electric driving device or the flow rate adjusting device is provided with a variable means for changing the medium heating power position. This makes it possible to set the medium heating power according to the characteristics of the stove. Appropriate heating power for medium heating depends on the cooking content, capacity and type of pot used, and there is no single heating that can satisfy all of these conditions. It is possible to make the appliance easy to use by changing the medium heat, such as setting one heat for stew, setting the medium heat to 1000 Kcal / h and setting the other one for oil to 2200 Kcal / h.

Further, in the gas cooking device according to the present invention, the medium heating power position can be set in advance to a constant calorie position which differs for each gas type. According to this configuration, the medium heating power position can be set in advance to a constant calorie position different for each gas type, and even with the same stove depending on the gas type, the weak heating power and the high heating power are not the same from the combustion performance of the burner. The medium heat power differs depending on the gas type when it is fixed at the position, but the medium heat power position can be changed, so that it is possible to provide an inexpensive appliance by setting the medium heat power slightly different for each gas type at the factory shipment. .

The gas cooker of the present invention is constituted by a governor in which the flow rate control device is driven by an electric drive device to change the flow rate. Since the governor is used, the gas cooker is also capable of responding to primary gas pressure fluctuations. The set secondary gas pressure has a characteristic of being constant, and stable heating power adjustment can be performed.

Further, in the gas cooker of the present invention, the flow rate control device is constituted by a needle mechanism driven by an electric drive device. It is possible to provide a product that can be mounted by only partially changing it. In addition, gas type conversion is easy.

The gas cooker of the present invention has a configuration in which the flow rate control device is provided with a bypass hole for the minimum flow rate. For example, when the calorie is as small as 400 Kcal / h in the governor, the governor pressure becomes a very small gas pressure. Adjusting this was difficult due to the temperature characteristics of the diaphragm, spring constant, etc.However, the minimum flow rate can be easily secured by the bypass hole, and unnecessary fire suppression and low calorie variation can be suppressed. it can.

In the gas cooker according to the present invention, the needle mechanism comprises a needle receiver, a needle slidably provided so as to vary the passage area of the needle receiver, and a cam for sliding the needle. Is driven by an electric driving device and an elastic member is interposed between the electric driving device and the cam so that the needle is slid to buffer an overload after the needle is brought into contact with the needle receiver. .

As described above, from the correlation between the temperature of the pan bottom temperature sensor 2 and the set temperature of the temperature control function, it is possible to appropriately select the low, medium, and high heating power by the heating control means 24.

FIG. 9 shows an example of a schematic flow of the drive judging means 31, in which it is judged whether the sensor temperature is normal (sensor disconnection, short circuit, etc.) 67, and if abnormal, goes to an abnormality processing route 68 to be described later. In this case, it is determined whether the thermocouple electromotive force is normal. If it is abnormal, go to an abnormality processing route 68 described later,
If the ignition is normal, it is determined whether it is the first ignition 70, and if it is the first ignition, it is confirmed that the position is the strong heating power 71, and if it is not the strong heating position, the output is set to the "strong heating power position" 72

If it is not the first time, it is determined whether or not there is a change in the thermal power from the previous stage. If yes, it is determined whether or not the current thermal power and the changed thermal power are different.
It is determined whether the changed heating power is the high heating power position 75, and if so, an output to set the “high heating power position” is output 76, otherwise, it is determined whether the changed heating power is the medium heating power 77, and if so, the output is set to the medium heating power position 78, otherwise output to the low heating power position 79.

It is determined whether the output state of any of the above is the heating power UP direction 80, if it is the UP direction, it is a low-speed movement 81, otherwise it is a medium-speed movement 82, and from the time of movement, the electric timer is turned ON 83 and the target position is reached. It confirms whether it has reached 84 and returns to the original.

If it has not reached, it is determined whether or not the elapsed time has elapsed X seconds 85. If it has elapsed, the process goes to the abnormality processing route 68. The abnormality processing route 68 sets the safety valve output to O

As described above, the heating power can be reliably adjusted to the target heating power position, and when the heating power is changed from low to high, the heating power can be slowly increased.

FIG. 10 shows another example of the schematic flow of the drive judging means 31. The same contents as those in FIG. 9 are denoted by the same reference numerals, and description thereof will be omitted. Only different parts will be described.

It is determined 70 whether the ignition is the first time, and if it is the first time, it is determined whether the electric drive unit 18 is not at the center stop position 89, and if not, the center stop position output is turned ON 90, and the electric timer ON 9
Go to 1 and judge whether it has reached the central stop position 92, if not, judge whether X seconds have elapsed 93, and if it has elapsed go to the abnormality processing route 68.

Incidentally, it is determined whether or not the normal thermal power change has been performed and the target position has been reached (84). If the target position has been reached, the process goes to the central stop position output ON90, but if not, it is determined whether X seconds have elapsed (85). If it is, it is judged as the first time 94, 1
In the case of the second time, the center stop position output is turned ON90. 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 shown in FIG. 9, the electric driving device 18 can be always returned to the center stop position after the change of the thermal power. If the electric driving device 18 does not reach the target heating power position due to some trouble, the electric driving device 18 is returned to the center stop position, and the heating power can be manually adjusted as described later.

FIG. 11 shows still another example of the schematic flow of the drive judging means 31. The same contents as those in FIG. 10 are denoted by the same reference numerals, and description thereof will be omitted. Only different parts will be 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 high nor low 95, the current thermal power position is stored 96 and the process proceeds to the next stage. If the current thermal power is high or low, the medium thermal power is set as the memory thermal power position 97.

As described above, in this case, the strength before the change,
By storing the heating power other than the low heating power position, it is possible to return to the medium heating power position of the stored original heating power after moving the low heating power position.

FIGS. 12 and 13 show an embodiment of the electric driving device 18 and the flow control device 17 of the heating control means 24, in which a governor mechanism is used for the flow control device 17. FIG. FIG. 12 shows an electric drive device 18 and a flow control device 17.
FIG. 13 shows a governor type flow control device 17.
It is sectional drawing of the main part of FIG.

The electric driving device 18 includes a geared motor 98,
Geared motor mounting frame 98-1, switch element 9
9, a cam 101 having a switch element operating piece 100 and a spring A102, a flow control device 17 includes a governor body 103, a diaphragm 104, a spring B105, a valve 10
6, a protection plate 107 and a governor pin 108.

This heating control means 24
04 changes the governor secondary pressure by pressing the governor pin 108 to vary the spring load of the spring B105 by pressing the governor pin 108 with the force for pushing up the spring B105, and changing the governor pin 108 by rotating the cam 101 with the geared motor 98. Adjust the heating power by changing the holding stroke.

At this time, the heating power setting (strong / weak) position is
01 is set by turning on and off the switch element 99 by the switch element operating piece 100 provided at 01.

In the drawing, reference numeral 4 denotes a bypass nozzle 4 which may or may not be used, and which is 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 heating power position, only the SW1 of the switch element 99 is ON and the gas pressure is low, and at the high heating power position, only the SW2 is ON and the gas pressure is high. Here, the cam shapes related to the heat power adjustment are represented by A curve and B curve, and the respective gas pressure curves are represented by A curve and B curve. In order to prompt the attention that the thermal power changes in the power, the B-curve cam shape that gradually increases the thermal power while gradually increasing the awareness is more suitable than the A-curve shape. It adopts a cam shape that changes from low heat to high heat in about 2 seconds.

As described above, the heating power can be changed by the electric driving device 18, and even if the electric driving device 18 is driven at a constant speed by modifying the shape of the cam 101, the amount of change in the flame is initially suppressed. Can raise the awareness that the flame will increase. Further, since the flow rate control device 17 is a governor system, the effect that the secondary gas pressure becomes the same thermal power even when the primary gas pressure changes can be expected, and stable thermal performance can be provided.

FIGS. 15 and 16 show that the switch element 99 has two switches.
FIG. 15 is a perspective view showing a means for providing a medium heat position, and FIG. 15 is a perspective view showing a means for providing a medium heat position. The cam 101 has switch element operating pieces 100A and 100B and a medium heat position switch element. An operating piece 100A + B is provided.

FIG. 16 shows the flow rate when the cam 101 is used. The rotation angle of the cam 101 on the abscissa indicates the low heating position, the medium heating position, and the high heating position, and the ordinate indicates the time. Of the stroke of the cam 101 and the switch elements 99-1 (SW1) and 99-2 (SW2)
In the ON-OFF state.

The following (Table 1) shows the switching element 99-1
(SW1) indicates the relationship between the mode of the switch element 99-2 (SW2) and the heating power position, and indicates that the mode 2 and the mode 4 cannot be discriminated. This means that, for example, when the mode is shifted from the mode 1 to the mode 3, the mode 3 is passed through the mode 2, the mode is switched to the mode 3, and the drive is turned off. 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) have been turned on, to reverse the drive direction and shift to mode 3. When the power is turned off in the mode 2 or 4 position, the current position becomes the mode 2 or 4
It is unknown. Therefore, when the power is turned on from OFF to ON, the drive determining means 31 switches the electric driving device 18 to the thermal power UP.
It is indicated that it is necessary to operate in the direction and shift the mode to 5.

[0110]

[Table 1]

As described above, in this example, the switching element 9
Even if there are two 9s, the weak, strong, and medium heating power positions can be confirmed, the number of switch elements 99 and the wiring processing associated therewith can be reduced, and the number of parts can be reduced. .

However, there is an inconvenience that the intermediate position cannot be determined with the two switch elements 99 and a device for use in the heating control means 24 needs to be devised.

FIG. 17 and FIG.
FIG. 17 is a perspective view showing a means for providing a medium heat position, and FIG. 17 is a perspective view showing a means for providing the medium heat position. The cam 101 has switch element operation pieces 100A and 100B, and the medium heat position switch element. An operating piece 100C and a switch element operating piece 100A + B + C for the middle heating power position are provided, and the switching element operating piece 100C is continuous from the low heating power position to the middle heating power position.

FIG. 18 shows the state of the flow rate when the cam 101 is used. The rotation angle of the cam 101 on the horizontal axis includes a low heating power position, a medium heating power position, and a high heating power position, and the vertical axis indicates the time. Shape of the cam 101 and the switch element 99-1
(SW1), the ON / OFF state of the switch element 99-2 (SW2), and the switch element 99-3 (SW3).

The following (Table 2) shows the switching element 99-1
(SW1), 99-2 (SW2), 99-3 (SW3)
Represents the relationship between the mode and the heating power position, and indicates that all the modes 1 to 5 can be immediately identified. This means that, for example, when the mode is shifted from the mode 1 to the mode 3, the mode 2 is set to the mode 3 and the driving device is turned off, and when the driving device rotates by inertia and cannot be stopped suddenly, the mode becomes the mode 4.

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

[0117]

[Table 2]

As described above, in this example, the switching element 9
The use of three 9s has the advantage that the current position can be determined at any position, the target thermal power can be moved in a short time, and the control method of the heating control means 24 can be simplified.

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

FIG. 20 shows that the cam B101-1 is provided with a scale around the adjustment hole 110 so that the set position can be determined.

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 suitable for each gas type is selected, It shows that the value of the weak burning amount and the strong burning amount differ depending on the gas type and the burner burning ability and the burning property of each gas, and it is necessary to move the middle burning power position when the middle burning power is the same burning power. I have.

For example, in the case of 13A, the high heat power is 4000 Kcal
/ h, low heat power is 400Kcal / h, medium heat power is 1500Kc
A / al point for al / h, 3800 for LPG
Kcal / h, low heat power is 500Kcal / h, medium heat power is 150
B point for 0Kcal / h, 320L for L1
0Kcal / h, low heat 600Kcal / h, medium heat 15
To make it 00 Kcal / h, the point C is required.

Therefore, the position of the scale of the adjusting hole 110 at which the medium thermal power becomes the same calorie for each gas is confirmed in advance, and the factory can be shipped according to the scale of the adjusting hole 110 corresponding to each gas. .

As the cam 101 rotates, the needle 111 adjusts the heating power while changing the passage area, and finally contacts the needle receiver 113. When the cam 101 is further rotated, the cam 101
By keeping the needle position constant against the spring C112 and reducing the connection gap between the connection pin 114 at the leading end a of the geared motor 98 and the slit portion 115 of the cam 101, the device is prevented from being destroyed. Welding ensures minimum flow accuracy.

FIG. 24 shows the rotation angle of the cam 101 on the abscissa, 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 ordinate. At the low heating power position, only switch element 99-1 (SW1) is O
In the N state, the gas pressure is low, and when a high heating power position is reached, only SW2 is turned on, and the gas pressure increases. Here, the cam shapes related to the heat power adjustment are represented by A curve and B curve, and the respective gas pressure curves are represented by A curve and B curve. In order to prompt the attention that the thermal power changes, the B-curve cam shape, which gradually increases and raises the thermal power while raising awareness, is more suitable than the A-curve cam shape. The cam shape is changed so that it takes about 2 seconds to change to high heat.

As described above, even in this example, the heating power can be changed by the electric driving device 18, and even if the electric driving device 18 is driven at a constant speed by devising the cam shape, the amount of change in the flame is initially suppressed. The user can be conscious of the increase in the flame.

FIGS. 31 to 33 show an example in which the heating power can be adjusted both electrically and manually.

FIG. 31 schematically shows the electric driving device 18. The electric driving device 18 includes a geared motor 98 mounted on a geared motor mounting frame 98-1, a cam 101 and an operating rod 123 movable by the geared motor 98, and a plurality of motors provided on the cam 101. ON-OF by the switch element operating piece 100
It is composed of a plurality of switch elements 99 that perform the F operation.

On the other hand, the heating power control lever 10 is
And the needle pin 116 is pinched by the pinching portion 10-1 from the fulcrum P of the heating power adjustment lever 10, and the needle pin 116 is rotated by the rotation of the heating power adjustment lever 10. The needle 111 is vertically movable 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 heating power control lever 10 is not particularly limited as long as it controls the gas amount, in addition to the specific mechanism described in each of the above embodiments. It does not do.

FIG. 32 shows the operating rod 123 of the electric drive device 18.
And the relationship between the power control lever 10 and the power control lever 10. When the operating rod 123 is at the point A (center stop position) even when the movable range W of the power control lever 10 is moved fully left and right, the control of the power control lever 10 is performed. The shape of the operation rod hole 10A is set so that the gaps W1 and W2 are secured so that the operation rod hole 10A is in the operation rod hole 10A and does not abut on the heating power adjustment lever 10.

In this state, when the operating rod 123 is moved and moved from the point A (center stop position) to the point B (low heat power position), the operating rod 123 comes into contact with the end surface of the operating rod hole 10A of the heat power adjusting lever 10, and the heat power adjusting lever 10 can be moved and moved. Similarly, when the operating rod 123 is moved from the point A to the point C (high heat power position), the heat power adjustment lever 10 also moves.

Here, in a state where the operating rod 123 is moved to the point C, the operating rod 123 must be moved at the same time in order to manually move the heating power adjusting lever 10.
For example, there arises a problem that a torque for moving the operation rod 123 is required or some means for separating the operation rod 123 from the electric driving unit is required.

In the present invention, in order to solve such a problem, as shown in the flowcharts of FIGS.
When the target position is reached by moving the movable member 23, for example, when moving from the point A to the point C, a series of operations for returning to the point A is performed so that the thermal power can always be manually adjusted.

FIG. 33 shows the state when the operating rod 123 is moved. The horizontal axis indicates the operating rod adjustment position (movement amount),
The vertical axis indicates the amount of change in the thermal power and the switching element 99−
1 shows switching states of 1 (SW1) and 99-2 (SW2). At low heat position, firepower is 40
0 Kcal / h, and the switching element 99-1 (SW1) is O
N, the switch element 99-2 (SW2) is in the OFF state. In the case of the central stop position, the switch element 99-1
(SW1) and switch element 99-2 (SW2) are both O
In the N state, the heating power can be adjusted in the range of 400 to 4000 Kcal / h by manually operating the heating power control lever 10 arbitrarily. In the case of the high heat power position, the heat power is 4000Kcal / h
The switch element 99-1 (SW1) is OFF, and the switch element 99-2 (SW2) is ON.

Therefore, for example, when adjusting the heating power from the center stop position to the strong heat position and returning to the center stop position, the electric drive unit rotates the geared motor 98 clockwise from the center stop position (both SW1 and SW2 are ON) to return to the strong fire position. It is confirmed that SW2 has been turned on by turning on SW2, and after stopping once, the geared motor 98 is rotated in the reverse direction (counterclockwise rotation) to switch SW1 and SW2.
When both are turned on, it is possible to stop after confirming that it has returned to the central stop position. This makes it possible to adjust the thermal power by electric drive, and it is also possible to manually adjust the thermal power by returning to the central stop position. Become.

The relationship between the operation rod 123 of the geared motor 98 and the operation rod hole 10A of the heating power adjustment lever 10 is as follows.
It is also possible to provide a rod hole in the electric drive
Is promising as an example of

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

In FIG. 32, when the operating rod 123 is moved to, for example, the point B, when the movable limit of the heating power control lever 10 is reached and the operating rod 123 is still moving,
The configuration is such that a load is gradually applied to the electric driving device 18 by deforming the operation rod 123 using the elasticity of the operation rod 123. Therefore, a sudden load is applied to the electric driving device 18 and the geared motor 98 can be prevented from being broken. For example, when the flow control device 17 is of 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 determined. You can get into it.

FIGS. 35 and 36 (a), (b) and (c) show other examples in which the heating power can be adjusted both by electric power and manually. FIG.
The electric driving device 18 includes a geared motor 98 mounted on a geared motor mounting frame (not shown), and a cam 10 movable by the geared motor 98.
1. It is composed of an operation piece 124 that sandwiches the heating power adjustment lever 10 with a specific width S, and a plurality of switch elements 99 that perform an ON-OFF operation by a plurality of switch element operation pieces 100 provided on the cam 101. Thermal power control lever 1
0 indicates that the needle pin 116 is pinched by the pinching portion 10-1 from the portion of the fulcrum P of the thermal power control lever 10, and the lever 1
By rotating 0, the needle pin 116 rotates,
The needle 111 is vertically movable with respect to a needle receiver (not shown) to control the flow rate.

The flow rate control device 17 for controlling the flow rate by operating the heating power control lever 10 is not particularly limited as long as it controls the gas amount, in addition to the specific mechanism described in each of the above embodiments. It does not do.

FIGS. 36 (a), 36 (b) and 36 (c) show the relationship between the operating piece 124 of the electric driving device 18 and the heating power adjustment lever 10. The movable range W of the heating power adjustment lever 10 is fully extended to the left and right. When the operation piece 124 is at the center stop position even when the operation piece 124 is moved, the heat power adjustment lever 10 is within the specific width S of the operation piece 124, and the gaps W1 and W2 are secured so as not to come into contact with the heat power adjustment lever 10. This shows a state where the width is set.

When the operation piece 124 is moved leftward 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 high heating power position. Similarly, when the operation piece 124 is moved rightward, the operation piece 12
4 comes into contact, and the heating power adjusting lever 10 can be moved to the weak heating power position.

However, if the operation piece 124 is moved to the left and moved to the low heating power position, moving the heating power adjusting lever 10 manually requires moving the operation piece 124 at the same time. A problem arises in that a torque is required to move the operation piece or some means for separating the operation piece 124 from the electric drive section is required.

In order to solve this problem, in the present invention, as described in the previous embodiment, 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 heating power position), By returning it to the central stop position, the thermal power can always be adjusted manually.

It is also promising as a second embodiment to provide a shape of the operation piece on the side of the heating power control lever 10 in view of installation conditions for the appliance. Also, the operating rod 123 of FIG.
Compared with the system, the heating power control lever 10 does not require any special processing, and has an effect that it can be attached to a current product having the heating power lever 10.

It should be noted that the operating piece movement amount when the adjustment movable range of the heating power adjusting lever 10 is moved by the operating piece 124, the amount of change in the heating power, the switch elements 99-1 (SW1) and 99
The content of the switching state of -2 (SW2) is the same as that of FIG. 33, and the description is omitted. FIG. 37 shows an example in which the movable contact portion between the operation piece 124 and the heating power control lever 10 has an elastic contact structure. The operation piece 124 is rotated by the rotation drive unit 124-1 and the elastic body unit 124-. 2. Divided into a distal end portion 124-3, and the elastic body portion 124-2 is made of an elastic material.

In FIG. 36, when the operating rod 124 is moved to, for example, a low heating power position, the movable limit of the heating power adjusting lever 10 is reached, and when the operating rod 124 is movable, the elasticity of the operating piece 124 is increased. The load is gradually applied to the electric drive device 18 by deforming the operation piece 124 by using. The operation and effect are the same as those in FIG. 34, and the description is omitted.

It is to be noted that the operation force adjusting lever 10 is
Is moved to adjust the heating power.
Similarly, it is promising as a second embodiment to make 6 movable.

Further, as a second embodiment, the operation of the needle pin 116 and the operation of the operation piece 124 are performed by rotating the transmission of the geared motor 98 into a disk-shaped and fan-shaped operation piece partially formed in a gear shape. Is also promising.

FIGS. 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 the outline thereof.
It has a geared motor 98 attached to the geared motor attachment frame 98-1, an electric drive gear 125 rotated by the geared motor 98, and a plurality of switch element operating pieces 100 provided on the electric drive gear 125.

The electric drive gear 125 has a configuration in which a circumferential hole 125A is provided corresponding to the convex portion 126.

Further, the heating power adjusting lever 10 sandwiches the needle pin 116 from the fulcrum P of the heating power adjusting lever 10 at the sandwiching portion 10-1, and the rotation of the heating power adjusting lever 10 causes the needle pin 116 to rotate. The needle 111 is vertically movable with respect to a needle receiver (not shown) to control the flow rate.

The flow rate control device 17 for controlling the flow rate by operating the heating power control lever 10 is not particularly limited as long as it controls the gas amount, in addition to the specific mechanism described in each of the above embodiments. It does not do.

FIGS. 39 (a), 39 (b) and 39 (c) show the operating relationship between the electric driving gear 125 of the electric driving device 18 and the heating power adjustment lever 10.

The notch width of the hole 125A is set so that the heating power adjusting lever 10 can be moved by the movable rotation angle α ゜ so that the protrusion 126 does not abut on the end of the hole 125A. Therefore, in this state, the heat power adjusting lever 10 can be operated independently of the electric drive gear 125, and the stopped state of the electric drive device 18 at this time is set to the central stop position.

Here, the electric driving device 18 is driven from the state where the heating power adjusting lever 10 is at the center, and the electric driving gear 125 is driven.
When the is rotated clockwise, the convex portion 126 of the heating power adjustment lever 10 becomes
It comes into contact with the right end of the hole 125A of the electric drive gear 125 and moves in accordance with the rotation of the electric drive gear (low heat position).

Similarly, the electric driving device 18 is driven from the state where the heating power adjusting lever 10 is in the center, and the electric driving gear 125 is driven.
When the counterclockwise rotation is performed, the convex portion 126 of the heating power adjustment lever 10 becomes
The electric drive gear 125 comes into contact with the left end of the cutout of the hole 125 </ b> A and moves in accordance with the rotation of the electric drive gear 125 (high heating power position).

However, in the state where the electric drive gear 125 is rotated to the left and moved to the high heating power position, it is not possible to manually move the heating power adjusting lever 10 without moving the electric driving gear 12.
5 also needs to be rotated at the same time.
Torque is required to rotate the electric drive gear 12
There arises a problem that some means for separating the electric drive unit from the electric drive unit 5 is required.

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

It should be noted that the amount of rotation when the adjustable range of the heating power adjusting lever 10 is rotated by the electric drive gear 125, the amount of change in heating power, and the switch elements 99-1 (SW1) and 99-2 (SW2). The content of the switching state is the same as that in FIG. 33, and the description is omitted.

According to the method of this embodiment, there is an effect that the transmission between the gears has a good transmission efficiency, and the torque of the electric driving device 18 is the smallest 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 driving device 18 includes a geared motor 98 mounted on a geared motor mounting frame (not shown), and a cam movable by the geared motor 98. 1
01, an operating rod 126, and a plurality of switch elements 99 that perform an ON-OFF operation by a plurality of switch element operating pieces 100 provided on the cam 101.

The flow rate control device 17 for controlling the flow rate by operating the heating power control lever 10 is not particularly limited as long as it adjusts the gas amount in addition to the specific mechanism described in each of the above embodiments. It does not do. The detailed description is omitted because it has a similar configuration to that of FIGS.

According to the above configuration, the heating power control lever 10
Since the electric drive unit 18 and the electric drive unit 18 are connected by the operation rod 126, even if a slight error occurs in the mounting position, the electric drive unit 18 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 driving device 18 comprises a geared motor 98 mounted on a geared motor mounting frame 98-1 and a pinion rack structure movable by the geared motor 98.

It is shown.

[0189]

[Table 3]

In FIG. 44, reference numeral 124 denotes an operation piece for moving and transmitting the heating power adjusting lever by the electric driving device 18.
The switch cam 101 fixed to the operation piece 124, the switch element operation pieces 100A, 10A provided on the switch cam 101
0B, 100A + B, 100C1, 100C2 and a plurality of switch elements 99.

FIG. 45 shows the operation piece 124 and the heating power control lever 1.
0 (a) illustrates that the operation piece 124 is located at the center stop position and the heating power adjustment lever 10 is movable in a range from a low to a high heating power position. (B) moves the heating power control lever 10 which was in the low heating power position by the electric drive to the medium-low heating power position, and (c) moves the heating power adjustment lever 10 which was in the high heating power position by the electric driving to the medium-high heating power. This shows the operation of the operation piece 124 when moving to the position, in which the heating power adjustment lever 10 which was in the low heating power position shown in FIG.
Is moved to the medium-low heating power position, the heating power adjustment lever 10 does not move to the middle heating power position even if the operation piece 124 is moved from the high heating power position side.

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

The switch element 99-1 has switch element operating pieces 100A, 100A + B, switch element 99-.
2 is a switch element operating piece 100B, 100A + B, and a switch element 99-3 is a switch element operating piece 100C.
1, 100C2 correspond.

At the low heating power position located on the horizontal axis, the heating power is 400 Kcal / h, and the switching element 99-1 (SW1)
Is ON, and the switch element 99-2 (SW2) is in the OFF state.
1 (SW1) and 99-2 (SW2) are both in the ON state, and the heating power can be manually operated by arbitrarily operating the heating power control lever 10. The adjustment at this time is 400-4000
It is possible in the range of Kcal / h.

At the time of the high heat power position, the heat power is 4000 Kcal / h
This indicates that the switch element 99-1 (SW1) is OFF and the switch element 99-2 (SW2) is ON.

As described above with reference to FIG. 33,
Providing the medium heating power position differently from the case of the strong heating power position is related to the drive control of the electric drive device 18. By rotating the rotation direction of the driving device 18 counterclockwise, the ON position of the switch element 99-3 (SW3) (the position of the switch element operating piece 100C1) becomes the medium heating power position.

Similarly, when the heat power position is adjusted in the direction of the high heat power position, the rotation direction of the electric driving device 18 is rotated clockwise to set the ON position of the switch element 99-3 (SW3) (the position of the switch element operating piece 100C2) to the medium heat power position. Becomes

Therefore, when adjusting to the middle heat power position, it is necessary to select the rotation direction according to the current position of the heat power adjustment lever 10, but since the heat power adjustment lever 10 has no means for determining the position, once the heat power adjustment lever 10 is Either move to the high or low heat power position to clarify the position and move to the medium heat power position, or discriminate from the temperature of the pan bottom temperature sensor 2 and the cooking mode condition to estimate the current position and
8 need to be determined.

By setting the switch element operating pieces 100, 100C1, 100C2 for determining the position of the medium heating power to be movable, the medium heating power can be freely set (the method of moving the medium heating power is shown in FIGS. 5 and 27). Is shown).

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

Since the switch element operating piece 100C is located at the heating power adjustment lever 10, the heating power adjustment lever 10 is temporarily moved to the high or low heating power position to clarify the position and then moved to the medium heating power position, or the pan bottom temperature sensor is used. No complicated processing such as estimating the current position and determining the driving direction of the electric driving device 18 by judging from the temperature 2 and the cooking mode condition is not required.

Further, the switch element operating piece 100 for operating the switch element 99-3 (SW3) is provided on the heating power adjusting lever 10.
Because of the provision of C, compared to the switch cam 101 system in which the heating power adjusting lever 10 of FIG. 15 is operated via the operation piece 124, the heating power of the medium heating power has a structure that is much easier to obtain a constant value.

FIG. 48 shows an example of changing the middle heating power position, and shows a cam B101-1 attached to the heating power adjustment lever 10.
Is provided with a switch element operating piece 100C for operating the switch element 99-3 (SW3).
In order to change the setting position of C, an adjustment hole 110 is provided in the cam B101-1, set to a target position, and a fixing screw hole 109 of the heating power adjusting lever 10 is fixed with a fixing screw 10B.
To fix the middle heat power position.

By making the middle heat power position variable,
For example, the medium heat power of the non-stick function is the heat power that can be simmered without boiling over after boiling, and is about 1000Kcal / h
The optimal thermal power can be set to about
Approximately 2,300 Kc of heat when fry tempura with general hob
It can be set to about al / h.

Therefore, when the purpose of use of the stove is limited in advance to prevent non-sticking, the medium heat power is set to about 1000 Kcal / h by the non-stick function. In addition, when proactively appealing for functional features, the position of 1000 Kcal / h is shown in Fig. 1.
As shown in the example in FIG. 2, since it differs depending on each gas type, it is possible to secure the medium thermal power position by finely adjusting the position at the time of shipment from the factory according to each gas type.

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

The medium heat power setting lever 130 can be operated on the operation panel together with the heat power control lever 10, and the user can set the medium heat power according to the cooking mode as desired.

FIG. 50 shows that the heating power adjusting lever 10 shown in FIG. 48 is provided with a plurality of medium heating power setting switches (FIG. 48).
In this example, the number of light transmitting holes 133 of the light emitting portion of the photoelectric switch 132 is provided on the heating power control lever 10 to count the number of light transmitted by the light receiving portion. The medium heat power position can be determined by determining the amount of movement.

For example, during cooking of boiled food, heating is generally carried out with high heat until boiling, and after boiling, depending on the food, cooking content, and the size of the pan, depending on the long experience of the user.
The medium heat power is set by the heat power control lever 10. Therefore, the medium thermal power is not constant but changes every time.

When the heating control means 24 checks whether or not it is in a scorched state during the cooking with the medium heating power, the heating power is temporarily reduced to the low heating power position. As a result of confirmation, when returning to the original heating power position without being in a scorched state, as a means for determining the original heating power position, shift from the medium heating power to the low heating power position, but at that time, reverse rotation by the numerical value counted by the light receiving unit As a result, it is possible to return to the original medium thermal power utilizing the years of experience set by the user.

Although the embodiment using the photoelectric switch has been described above, the shape of the cam 101 and the switch element 99 are described.
The second embodiment, in which the current position can be determined, can exhibit the same effect by using a combination of the above and an encoder. In addition, when the encoder is used, it becomes possible to know the user's thermal power control course.

Since the operation method has been described above, the description is omitted. In the case of the thermal power control lever 10 system, it is necessary to restrict the movable range of the thermal power control lever 10 to a slit shape on an operation panel (not shown). It is only necessary to provide a hole, so that there is no need for an infant to put a hand in the slit, and the appearance can be designed differently from the lever type.

FIG. 52 shows an example in which the heating power adjustment button 136 has a double structure, the inner button 137 is an ignition button, and the outer button 136 is heating power adjustment. The figure shows a case where the tip of the heating power adjustment lever 10 is formed in a gear shape 138, and the gear 136A is connected to the outer heating power adjustment button 136 so as to be connected and driven. Since the operation method has been described above, the description is omitted.

FIG. 53 shows that the ignition button and the heating power adjustment button are composed of the same component 139, the ignition / extinguishing operation is a pushing operation, the heating power adjustment is a turning operation, and the flow rate control mechanism by the heating power adjustment button 139; FIG. 3 is a diagram showing an example of a structure that is also used as a flow control device 17 of the heating control means 24.

When the button 139 is inserted and pushed into the shaft 141 from the case 140 having a push-push locking mechanism, it pushes the valve operating rod 142A of the cock body 142 to open a gas passage. In this state, whether the button 136 is popped out or pushed in depends on the configuration of the lock mechanism in the lock mechanism case 140, but this is not a necessary item of the present invention and a detailed description is omitted.

The gear portion 143 of the button 139 meshes with the electric drive gear B144 having a long gear shape of the flow control device 17, and when the button 139 is operated, the connection is maintained by sliding between the long gear shapes. Electric drive gear B1
By rotating 44, the needle 111 configured to transmit the rotation movably in the vertical direction is rotated.

When the needle 111 is rotated, it is inserted into a needle body 145 having a groove for moving the needle 111 in the vertical direction. Since the needle mechanism has been described above, the description is omitted.

The electric drive unit 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 on the electric drive gear 125.
