Description

  The present invention relates to a thermal power control apparatus that is incorporated in a gas stove and performs point fire extinguishing and thermal power control of a gas burner.

  As a conventional thermal power control device, there is known a thermal power control lever that adjusts the thermal power of a gas burner by swinging left and right, and a point-extinguishing button that performs point-extinguishing of the gas burner by pushing it (for example, , See Patent Document 1).

  In this case, when the fire extinguisher button is pushed when the gas burner is ignited, the electromagnetic safety valve is forcibly opened by the pushing force to supply gas to the gas burner, and the fire extinguishing button is pushed in the pushing direction. The ignition switch is turned on by the movement, and the sparker is activated to ignite the gas burner.

  After the ignition of the gas burner is completed, the hand is released from the fire extinguisher button, but the fire extinguisher button is slightly moved back to be held at the ignition position. When the gas burner is extinguished, the ignition position lock is released by pressing the fire extinguisher button again. If the hand is released from the fire extinguishing button in that state, the point extinguishing button returns to the initial fire extinguishing position, and the gas burner The gas supply to is stopped.

  When the thermal power adjustment lever is swung left and right, the needle valve built in the thermal power control device moves forward and backward to increase or decrease the amount of gas supplied to the gas burner, so that the thermal power of the gas burner is adjusted.

  Note that, when the point-extinguishing button is pushed in and ignited, only a small amount of gas is ejected from the gas burner when the position of the heating power adjustment lever is at the low fire position, so that it is difficult to ignite the gas burner even if the sparker is activated. On the other hand, if the heating power adjustment lever is in the high fire position at the time of ignition, a large amount of gas is ejected from the gas burner, which causes problems such as generation of loud sounds due to explosion and overflowing of flames around cooking utensils such as pans.

  Therefore, a cam plate is provided that moves by pushing the point fire extinguishing button, and a mechanism is provided for forcibly moving the heating power adjustment lever to a position corresponding to a predetermined ignition heating power via the needle valve by this cam plate during ignition operation. Is known.

JP 2011-47538 A (FIG. 4)

  In the conventional thermal power control device, when the thermal power control lever is swung left and right, the thermal power control lever may be rattled due to an assembly error or play. In addition, if the operation is too light when swinging, a cheap feeling is generated when the operation is performed, and a high-class feeling cannot be produced.

  In order to solve such a problem, for example, the conventional thermal power control apparatus is configured to generate a click feeling when the thermal power control lever is operated to a specific position. It is conceivable that an appropriate resistance can be generated when operating the heating power adjustment lever by configuring it to occur continuously.

  However, as described above, when the gas burner is ignited, when the fire power adjustment lever is moved in conjunction with a position corresponding to a predetermined ignition heat power by pushing a point fire extinguishing button, A new problem arises in that the resistance to the operation becomes a hindrance, and the fire extinguishing button must be pushed in with a great force.

  Accordingly, in view of the above-described problems, the present invention provides a thermal power control device that gives resistance to the operation of the thermal power adjustment lever, but the resistance does not interfere with the pressing operation when the ignition button is pressed during ignition. Is an issue.

In order to solve the above problems, a thermal power control device according to the present invention includes a thermal power control lever that adjusts the thermal power of the gas burner by swinging left and right in a state where no urging force is applied to any of the left and right directions , It is a thermal power adjustment device having a point-extinguishing button that performs point-extinguishing of the gas burner by pushing, and when igniting the gas burner by pushing the point-extinguishing button, in conjunction with the pushing operation of the point-extinguishing button , the thermal power adjusting lever by pushing force to be applied in this respect extinguishing button, in that a mechanism for swinging to a position corresponding to a predetermined ignition firepower is set between the low heat position and high heat position, during combustion control operation It is equipped with a resistance member that acts as a resistance when the thermal power adjustment lever is swung in contact with the thermal power control lever, and the gas burner is ignited by pressing the above-mentioned fire extinguishing button. When interlocking the thermal power adjusting lever by moving the resistance member to lower the resistance to thermal power adjusting lever in, characterized in that to reduce the pushing force of the point extinguishing button.

  As in the above configuration, when the thermal power adjustment lever is swung, a resistance feeling is generated by the resistance member, but when the ignition button is pressed during ignition, the resistance decreases so that the force to press the ignition button is reduced. I tried not to grow.

  As is apparent from the above description, the present invention causes a feeling of resistance when operating the thermal power adjustment lever so that the operation feels high-quality and the pressing of the fire extinguishing button becomes heavy at the time of ignition. Was prevented from occurring.

  With reference to FIG. 1, 1 is an example of a thermal power control apparatus according to the present invention. This thermal power control device performs point fire extinguishing and thermal power control of a gas burner not shown. When the gas burner in the fire extinguishing state is ignited, when the point fire extinguishing button 11 is pushed in from the front to the back (to the left in the figure), a micro switch (not shown) attached to the thermal power control apparatus 1 is shown. ) Is turned on and a sparker attached in the vicinity of the gas burner is activated, and a spark is generated between the gas burner and the sparker. Further, when the point fire extinguishing button 11 is pushed, the electromagnetic safety valve 12 is forcibly opened and gas is supplied to the gas burner, so that the gas burner is ignited.

  On the other hand, the amount of gas supplied to the gas burner is determined by advancing and retracting a needle valve built in the thermal power control apparatus 1. An engagement pin 13 perpendicular to the advancing / retreating direction of the needle valve is attached to the front end of the needle valve so as to penetrate vertically, and the thermal power adjustment lever 2 is engaged with the upper end of the engagement pin 13. In combination, the heating power adjustment lever 2 is swung in the left-right direction so that the needle valve is advanced and retracted via the engagement pin 13 to adjust the heating power.

  When the fire extinguishing button 11 is pushed in and the gas burner is ignited, if the heating power adjustment lever 2 is in a position corresponding to a low fire, the amount of gas ejected from the gas burner at the time of ignition is small, so that ignition may not be possible. On the other hand, if the thermal power control lever 2 is in a position corresponding to a strong fire during ignition, a large amount of gas is ejected from the gas burner during ignition, and an explosive noise is generated during ignition, or the flame is a cooking utensil such as a pan. There is a risk that it will overflow from the surroundings. Therefore, when the point fire extinguishing button 11 is pushed in and the gas burner is ignited, it is desirable that the heating power adjustment lever 2 is in a position corresponding to a predetermined ignition heating power.

  Therefore, referring also to FIG. 2, when the cam plate 3 that engages with the lower end portion of the engagement pin 13 is provided and the point fire button 11 is pushed in, a part of the point fire button 11 pushes the contact portion 31. The cam plate 3 is swung, and the needle valve is forcibly moved to an advance / retreat position corresponding to the ignition heating power via the engagement pin 13. Since the thermal power adjustment lever 2 is connected to the needle valve via the engagement pin 13, the thermal power control lever 2 is also linked to the ignition thermal power when the needle valve moves to the advance / retreat position corresponding to the ignition thermal power. Forcibly moved to the corresponding position.

  After ignition is completed, the heating power adjusting lever 2 is swung to adjust the heating power and cooking is performed, but if there is too much resistance when the heating power adjusting lever 2 is swung left and right, a high-class feeling is not felt during operation. . Therefore, as shown in FIG. 3, a protrusion 21 is formed on the lower surface of the thermal power adjustment lever 2, and a resistance member 4 that swings in the vertical direction and whose upper end 42 is urged upward is provided. By causing the upper end 42 of the resistance member 4 to come into contact with the projection 21 by the urging force, an appropriate resistance is produced when the heating power adjusting lever 2 is swung.

  However, as described above, when the point-extinguishing button 11 is pushed in and the gas burner is ignited, the thermal power adjustment lever 2 is swung to a position corresponding to the ignition thermal power. If the resistance acts on, the push of the fire extinguishing button 11 becomes heavy.

  Therefore, when the projection 14 is provided on the point fire extinguishing button 11 and the point extinguishing button 11 is pushed in, the projection 14 pushes the lower end 41 of the resistance member 4 to swing against the urging force, as shown in FIG. The upper end 42 is separated from the thermal power adjustment lever 2 so that no resistance is generated in the oscillation of the thermal power adjustment lever 2. Since the fire extinguishing button 11 returns to the near side after the ignition is completed, the upper end 42 of the resistance member 4 is again pressed against the heating power adjustment lever 2 by the urging force, and the resistance to the swinging of the heating power adjustment lever 2 is felt. Will occur.

  In the above embodiment, the upper end 42 of the resistance member 4 is completely separated from the heating power adjustment lever 2 at the time of ignition so that no resistance is generated. However, as shown in FIG. Further, the swing piece 5 is attached, and the contact portion 51 of the swing piece 5 is pressed against the thermal power adjustment lever 2 by the spring 52. At the time of ignition, the contact portion 51 is not completely separated from the thermal power adjustment lever 2. You may comprise so that the resistance with respect to the thermal-power adjustment lever 2 may reduce by pressing force reducing.

  In addition, this invention is not limited to an above-described form, You may add a various change in the range which does not deviate from the summary of this invention.
