Description

  The present invention relates to a thermal power adjustment device that is incorporated in a gas stove and adjusts the thermal power of a gas burner.

  The gas stove incorporates a thermal power control device that adjusts the thermal power of the gas burner by increasing or decreasing the amount of gas supplied to the gas burner. As an example of such a thermal power control device, an operating lever that swings in the horizontal direction is provided, and a slit-like window hole that is long in the left-right direction is formed on the front surface of the gas stove. Some are configured to adjust the heating power of the gas burner by projecting from the front side to the near side and swinging the operation lever in the left-right direction.

  In this configuration, when the control lever is swung left and right, the locus of the tip of the control lever becomes an arc shape, so that it protrudes most when the tip of the control lever is located at the center of the heating power adjustment range, and from the position to the left and right The amount of protrusion is shortened by swinging. The tip of the operating lever protrudes straight toward the front in the center of the heating power adjustment range, but tilts when it swings left and right.

  As a result, there is no sense of unity between the tip of the control lever and the front panel of the gas stove, and it is not possible to give a high-class feel to the operation of the control lever.

  Therefore, a guide member having a longitudinal opening in the left-right direction is fitted into the window hole of the front panel, and a gripping member that moves linearly left and right within the opening of this guide member is provided, and this gripping member and the tip of the operation lever are engaged Thus, there is known a mechanism in which the operating lever swings and adjusts the heating power of the gas burner by moving the gripping member linearly left and right (see, for example, Patent Document 1).

JP 2010-196958 A (FIG. 4)

  In the above-mentioned conventional one, the thermal power control device is fixed to the instrument body separate from the front panel of the gas stove. Deviation may occur. For this reason, the positions of the gripping member held by the guide member and the tip of the operation lever vary, and there is a possibility that an individual that cannot smoothly move the gripping member in the left-right direction may be generated.

  In view of the above problems, the present invention has an object to provide a thermal power control apparatus that can perform thermal power adjustment in a straight line without any variation in a configuration in which the thermal power control is linearly moved to the left and right. And

In order to solve the above problems, the thermal power control apparatus according to the present invention includes an operation lever that swings in the horizontal direction at the top of the main body, and the amount of gas supplied to the gas burner is increased or decreased by swinging the operation lever. In a thermal power control apparatus that adjusts the thermal power of a gas burner, a housing is fixed to the main body, a guide bar is attached to the housing so as to extend in the left-right direction, and is linearly moved in the left-right direction while being guided by the guide bar. the moving element is provided, by engaging the moving member to the tip portion of the operating lever, to oscillate the lever by moving the movable element to the right and left, there is configured to perform combustion control , set to the housing, to form a wall portion that faces the mover over the entire moving range of the moving element, the moving element of the sliding portion in contact with a predetermined biasing force against the wall portion , The frictional force between the sliding portion and the wall portion during movement of the movable element configured to sense resistance occurs, and, in the housing, over the entire moving range of the moving element, a splash from the front In addition to forming a splash-proof part that shields, a slit-like opening that is long in the left-right direction is formed in this splash-proof part, and a plate-like operation part that passes through the opening and extends forward is provided on the moving element . Due to the biasing force acting on the sliding portion, the operation portion is brought into contact with the ceiling portion of the slit-shaped opening so that a gap through which a liquid material flows is not formed between the operation portion and the ceiling portion of the opening. It is characterized by that.

  Since the guide bar for guiding the moving element is attached to the main body of the thermal power control apparatus, the guide bar is accurately positioned with respect to the main body, and the position of the guide bar with respect to the main body does not vary.

In addition, if the movement of the moving element from side to side is too light, the feeling of operation will not be high-quality. In that case, a wall portion facing the mover is formed in the casing over the entire movement range of the mover, and a sliding portion that contacts the wall portion with a predetermined urging force is formed on the mover. to provided, and so a sense resistance caused by the friction force between the sliding portion and the wall portion during movement of the movable element.

In addition, liquid substances such as boiled spills may drop from above, but liquid detergents may be sprayed from the front. In order to prevent the splash from the front from being applied to the moving element, a splash-proof part that shields the splash from the front is formed in the casing over the entire movement range of the moving element, and the splash-proof part. A slit-like opening that is long in the left-right direction is formed on the slider, and a plate-like operation part that extends forward through the opening is provided on the moving element . Further, this operation is performed by the biasing force that acts on the sliding part The part was brought into contact with the ceiling part of the slit-shaped opening so that a gap through which the liquid material flows was not formed between the operation part and the ceiling part of the opening .

  As is clear from the above description, in the present invention, since the guide bar for guiding the moving element to be actually operated is attached to the main body of the thermal power control device, the positions of the thermal power control device and the guide bar vary from individual to individual. Therefore, the operational feeling can be stabilized.

  1 and 2, reference numeral 1 denotes a thermal power adjusting device, and an operation lever 11 is provided on the upper portion of the thermal power adjusting device 1 so as to be swingable in the left-right direction. When the operation lever 11 is swung in the left-right direction, the needle valve 12 moves in the front-rear direction, and the flow rate of the gas supplied to the gas burner (not shown) is increased or decreased. In the present invention, the casing 2 is fixed to the main body of the thermal power control apparatus 1.

  A cylindrical guide bar 3 is provided in the housing 2 so as to extend in the left-right direction, and a moving element 4 is held along the guide bar 3 so as to be movable in the left-right direction. The moving element 4 is provided with a plate-like operation portion 41 extending toward the front side. The casing 2 is provided with a splash-proof portion 21 on the front side, and the operation portion 41 passes through a slit-like opening 23 formed in the splash-proof portion 21 so as to be longitudinal in the left-right direction. It extends.

  An engagement pin 11 a is fixed to the tip of the operation lever 11, and the engagement pin 11 a is engaged with an engagement groove 4 a formed on the lower surface of the moving element 4. A sliding member 42 is provided on the upper surface of the moving element 4 by being urged upward by a spring 43.

  A wall portion 22 is formed as a part of the housing 2 at the upper portion during movement, and the sliding member 42 is pressed against the lower surface of the wall portion 22 by the biasing force of the spring 43. Assuming that the contact point between the sliding member 42 and the wall portion 22 is A, the movable element 4 receives the reaction force of the urging force from this point A. The movable element 4 uses the guide bar 3 as a fulcrum in FIG. You will receive a counterclockwise moment.

  On the other hand, as described above, since the operation unit 41 passes through the opening 23, the operation unit 41 is pressed against the upper surface of the opening 23. If this point is point B, since the operation unit 41 is plate-shaped, when a liquid material such as simmering drops from above, the liquid material tends to stay on the upper surface of the operation unit 41. Even if the liquid material flows through the upper surface to the back side, since there is no gap at point B, the liquid material cannot flow any further to the back side and flows down further from the left and right of the operation unit 41. Become.

  Referring to FIG. 3, when the operation unit 41 is moved to the left and right, the movable element 4 moves to the left and right along the guide bar 3. At this time, the sliding member 42 is moved to the lower surface of the wall portion 22 as described above. Therefore, when the operation unit 41 is operated left and right by the frictional force generated at the point A, an appropriate resistance is generated.

  Since the engaging pin 11a is engaged with the engaging groove 4a formed in the moving element 4, when the moving element 4 moves to the left and right, the operation lever 11 swings in the left and right direction in conjunction with the movement. As a result, the heating power of the gas burner is adjusted.

  By the way, the splash-proof portion 21 is formed so that liquid detergent or the like sprayed from the front does not reach the moving element 4 or the needle valve 12. However, since the opening 23 opens toward the front, it passes through the opening 23. Therefore, there is a possibility that the splash may enter inside from the splash-proof portion 21. Therefore, when it is desired to completely prevent the splash entering through the opening 23, the splash-proof portion is divided into an upper splash-proof portion 21a and a lower splash-proof portion 21b as shown in FIG. You may comprise so that the opening 23 may face downward by projecting 21a to the near side and extending it below.

  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.
