Japanese Patent Laying-Open No. 2004-340432 (page 8, FIG. 15)

  In the conventional thermal power control apparatus for gas combustion equipment, an engagement body that is projected and biased by a spring is used to provide a click feeling so that the position of the thermal power control operation tool can be easily understood. The structure for imparting a click feeling is complicated due to the fact that the spring must be supported so as to move by the biasing force of the spring and the spring that biases the engaging body must be provided. There are disadvantages and improvements are desired.

  The present invention has been made in view of the above circumstances, and its purpose is to provide a gas combustion device capable of simplifying the structure for providing a click feeling in order to make the position of the thermal power adjustment operation tool easy to understand. Is to provide a thermal power control device.

A thermal power control apparatus for a gas combustion device according to the present invention includes a reciprocating valve body that adjusts the amount of gas supplied to a burner and a reciprocating thermal control tool that are controlled by a reciprocating operation of the thermal power control tool. The valve body is linked by a cam-type linkage mechanism so as to reciprocate, and the first characteristic configuration is
As a member constituting the cam-type linkage mechanism, a movable member that reciprocates by the reciprocating operation of the heating power adjusting operation tool while being pressed against the sliding surface by the pressing force generated by the reciprocating operation of the heating power adjusting operation tool. A body is provided,
The movable body is generated by a reciprocating movement operation of the thermal power adjustment operation tool at a position where the movable body is located when the thermal power adjustment operation tool on the sliding surface is located at a specific position of the movement range for thermal power adjustment. It is characterized in that a depression for providing a click feeling that provides a click feeling by entering only with a pressing force is provided.

  That is, when the thermal power adjustment operation tool is reciprocated, the movable body is reciprocated with the pressing force generated by the operation being pressed against the sliding surface. When the movable body is located at a specific position in the adjustment movement range, the movable body enters the depression for giving a click feeling provided on the sliding surface, thereby giving a click feeling to the operator's hand having the heating power adjustment operation tool. The operator can understand that the heating power adjustment operation tool is located at a specific position in the heating power adjustment moving range.

  A movable member that reciprocates by a reciprocating operation of the heating power adjusting operation tool while being pressed against the sliding surface by a pressing force generated by a reciprocating operation of the heating power adjusting operation tool as a member constituting the cam type linkage mechanism. By paying attention to the body, a click feeling imparting recess is provided on the sliding surface that moves in a state in which the movable body is pressed, thereby giving a click feeling to the operator's hand having the thermal power adjusting operation tool. Therefore, it is only necessary to provide a recess for giving a click feeling on the sliding surface without using a special biasing mechanism or the like to give a click feeling. A click feeling can be given for easy understanding.

  In other words, when the reciprocating valve body and the reciprocating operation type thermal power adjustment tool are linked by a cam-type linkage mechanism so that the valve body is reciprocated by the reciprocating operation of the thermal power adjustment operation tool. Therefore, it is necessary to receive the reaction force of the cam operation by the cam-type linkage mechanism. Therefore, as a member constituting the cam-type linkage mechanism, the pressing force generated by the reciprocating movement operation of the heating power adjusting operation tool is applied to the sliding surface. In this state, there is a movable body that reciprocates by the reciprocating operation of the heating power adjusting operation tool. Therefore, by effectively using the movable body and the sliding surface against which the movable body is pressed, it is possible to give a click feeling with a simple structure in order to make the position of the thermal power adjustment operation tool easy to understand. .

  In short, according to the first characteristic configuration of the present invention, it is possible to provide a thermal power control apparatus for a gas combustion device capable of simplifying the structure for giving a click feeling in order to make the position of the thermal power control operation tool easy to understand.

The second feature configuration of the present invention is in addition to the first feature configuration described above.
As the sliding surface, a sliding surface on the heating power decreasing side on which the movable body slides when the valve body is moved on the heating power decreasing side, and the moving body on moving the valve body on the heating power increasing side. One of the sliding surfaces on the thermal power increasing side on which the slid slides is provided with the depression for imparting the click feeling.

  That is, as the sliding surface on which the movable body slides, the sliding surface on the heating power decreasing side on which the movable body slides when the valve body is moved on the heating power decreasing side and the sliding surface on which the valve body is moved on the heating power increasing side There is a sliding surface on the thermal power increasing side on which the movable body slides, but one of the sliding surfaces is provided with a depression for imparting a click feeling. Is operated to a specific position within the moving range for adjusting the thermal power, it becomes easy to operate the thermal power in the same state.

  In addition, if the sliding surface on which the movable body slides is specified, both the sliding surface on the thermal power reduction side and the sliding surface on the thermal power increase side specify the movement range for thermal power adjustment of the thermal power control operation tool. It is conceivable to provide a click feeling concavity corresponding to the position, but due to the influence of play etc. existing in the cam type linkage mechanism, the thermal power adjustment operation tool was operated to a specific position in the thermal power adjustment movement range. Sometimes, the so-called hysteresis occurs where the position of the valve element is different between when the thermal power adjustment operation tool is moved toward the thermal power reduction side and when the thermal power adjustment operation tool is moved toward the thermal power increase side. There is a risk of doing.

  For this reason, if a recessed portion for giving a click feeling is provided on both the sliding surface on the heating power decreasing side and the sliding surface on the heating power increasing side in correspondence with the specific position of the heating power adjustment moving range of the heating power adjusting operation tool. When the thermal power adjustment operation tool is operated to a specific position in the thermal power adjustment movement range, the thermal power adjustment operation tool is moved toward the thermal power reduction side, and the thermal power adjustment operation tool is moved to the thermal power increase side. Although there is a risk of inconvenience that the thermal power differs depending on the case, the thermal power control operation is performed by providing a click feeling concavity on one of the sliding surface on the thermal power decreasing side and the sliding surface on the thermal power increasing side. When the tool is operated to a specific position within the movement range for adjusting the thermal power, the thermal power can be operated in the same state.

By the way, when a recess for giving a click feeling is provided on one of the sliding surface on the heat reduction side and the sliding surface on the heating power increase side, the thermal power adjustment operation is performed once so as to exceed the specific position as necessary. After operating the tool, it is necessary to operate the heating power control tool toward a specific position.
In other words, for example, in the case where a click feeling imparting recess is provided on the sliding surface on the thermal power reduction side, the click feeling is imparted only when the thermal power adjustment operation tool is operated on the thermal power reduction side. When the position of the thermal power control tool is at the position where the thermal power is reduced from the specified position, the thermal power control tool is once moved to the thermal power increasing side until it exceeds the specific position, and then the thermal power control tool is moved to the thermal power decreasing side. It is necessary to operate.

  On the contrary, for example, when a click feeling imparting recess is provided on the sliding surface on the heating power increasing side, a clicking feeling is given only when the heating power adjusting operation tool is operated on the heating power increasing side. Therefore, when the current position of the thermal power adjustment operation tool is on the heating power increasing position with respect to the specific position, the thermal power control operating tool is once operated to the thermal power reduction side until the position exceeding the specific position, and then the thermal power control operating tool is It is necessary to operate to the side where the thermal power increases.

In the case where a plurality of specific positions that are different positions are provided as the specific position, the click feeling imparting recesses corresponding to all of the plurality of specific positions are provided on the sliding surface on the heating power decreasing side and the heating power increasing side. It is not necessary to concentrate on any one of the sliding surfaces, and a plurality of click feeling imparting recesses corresponding to a plurality of specific positions are provided on the sliding surface on the heating power decreasing side and the sliding surface on the heating power increasing side. It can be dispersed and provided.
In other words, a click feeling imparting recess for one specific position may be provided on one of the sliding surface on the heating power decreasing side and the sliding surface on the heating power increasing side.

  In short, according to the second characteristic configuration of the present invention, in addition to the operational effects of the first characteristic configuration described above, when the thermal power adjustment operation tool is operated to a specific position in the thermal power adjustment moving range, the thermal power is made to be in the same state. It is possible to provide a thermal power control device for a gas combustion device that can be operated.

In addition to the first feature configuration or the second feature configuration described above, the third feature configuration of the present invention includes:
The valve body is a slide type valve body, and the heating power adjusting operation tool is configured in a swinging lever shape,
A cam operation hole into which the operated pin is attached to the valve body in a state parallel to the swing axis direction of the thermal power adjusting operation tool, and the operated pin is inserted into the thermal power control operating tool. Is provided to constitute the cam-type linkage mechanism,
The operated pin is the movable body, and the inner surface of the cam operation hole in which the operated pin slides is the sliding surface.

  That is, when a slide type valve body is used as the valve body, the thermal power adjustment operation tool is configured in a swinging lever shape and is directed in a direction parallel to the swing axis direction of the thermal power adjustment operation tool. By inserting the operated pin attached to the valve body into the cam operating hole provided in the heating power adjusting operation tool, a cam type linkage mechanism having a simple configuration with the operated pin and the cam operating hole as main parts is configured. be able to.

  When the cam-type linkage mechanism is configured in this way, the operated pin is pressed against the inner surface of the cam operation hole by the pressing force generated by the reciprocating operation of the heating power adjustment operating tool. Since it is reciprocated by a reciprocating operation, the operated pin is a movable body, the inner surface of the cam operating hole in which the operated pin slides is the sliding surface, and the depression for imparting a click feeling is provided on the cam operating hole. By providing it on the inner surface, a click feeling can be imparted in order to make the position of the heating power adjusting operation tool easier to understand.

  And since the depression for giving a click feeling is provided in the inner surface of the cam operation hole formed in the heating power adjustment operation tool, the click feeling generated when the operated pin enters the depression for giving the click feeling is the heating power adjustment. Since it is directly given to the operation tool, it becomes easy to give a sufficient click feeling to the operator who supports and operates the heating power adjustment operation tool.

  In short, according to the third characteristic configuration of the present invention, in addition to the operational effects of the first characteristic configuration or the second characteristic configuration, the cam type linkage mechanism is simplified, and the thermal power adjustment operation tool is supported. It is possible to provide a thermal power adjustment device for a gas-combustion apparatus that can easily give a sufficient click feeling to an operating operator.

In addition to the first feature configuration or the second feature configuration described above, the fourth feature configuration of the present invention includes:
The valve body is a slide type valve body, and the heating power adjusting operation tool is configured in a swinging lever shape,
A cam operating hole into which the operated pin is attached to the valve body in a state parallel to the pivot axis direction of the thermal power adjusting operation tool, and the operated pin is inserted into the thermal power adjusting operating tool. Is provided to form a cam-type linkage mechanism,
The valve body is supported by the valve casing so as to be rotatable around an axis along the sliding direction, and a slit groove for guiding the operated pin in the sliding direction of the valve body is provided in the valve casing,
The operated pin is the movable body, and the inner surface of the slit groove on which the operated pin slides is the sliding surface.

  That is, when a slide type valve body is used as the valve body, the thermal power adjustment operation tool is configured in a swinging lever shape and is directed in a direction parallel to the swing axis direction of the thermal power adjustment operation tool. By inserting the operated pin attached to the valve body into the cam operating hole provided in the heating power adjusting operation tool, a cam type linkage mechanism having a simple configuration with the operated pin and the cam operating hole as main parts is configured. As a result, the cam type linkage mechanism can be simplified.

  In the case of configuring the cam type linkage mechanism in this way, when the operated pin is pressed through the cam operation hole, a force is applied to the valve body to rotate around the axis along the slide direction. However, in this characteristic configuration, the valve body is supported rotatably around the axis along the sliding direction, and the operated pin is guided by the slit groove provided in the valve body casing, that is, In order to prevent the operated pin from rotating around the axis along the sliding direction of the valve body, the valve body is received around the axis along the sliding direction by receiving the operated pin with the slit groove. It prevents the rotation.

  Since the operated pin provided for configuring the cam-type linkage mechanism is effectively used in this way, the valve body is prevented from rotating around the axis along the sliding direction. A rectangular shaft portion is formed in at least a part of the valve body, and a hole through which the valve body is inserted is formed in a rectangular tube-like hole into which the rectangular shaft portion is fitted, so that the valve body follows the sliding direction. Since the valve body can be formed in a columnar shape and the hole through which the valve body is inserted can be formed in a cylindrical shape, compared to using a rotation stop structure such as preventing rotation around the axis. The body mounting configuration can be simplified.

  When the operated pin provided on the valve body is guided by the slit-shaped groove, the operated pin is pressed against the inner surface of the slit-shaped groove by the pressing force generated by the reciprocating operation of the thermal power adjusting operation tool. Therefore, the operated pin is a movable body, the inner surface of the slit groove on which the operated pin slides is used as a sliding surface, and a depression for providing a click feeling. Is provided on the inner surface of the slit-like groove, so that a click feeling can be imparted in order to make the position of the heating power adjusting operation tool easy to understand.

  Further, since the depression for imparting a click feeling is provided on the inner surface of the slit groove for guiding the operated pin attached to the valve body in the sliding direction of the valve body, that is, a click feeling is provided in the valve body casing that supports the valve body. Since the concavity for imparting is formed, when the valve body is positioned at a position corresponding to the thermal power to which the click feeling should be imparted, the operated pin enters the concave for imparting the click feeling, and the thermal power adjusting operation Regardless of secular changes such as looseness of the tool, it will be performed accurately over a long period of time, and the thermal power when the click feeling is given to the thermal power control operation tool stabilizes over the long term, resulting in thermal power control It can be precisely adjusted to the heating power required by the operation tool.

  In short, according to the fourth characteristic configuration of the present invention, in addition to the operational effects of the first characteristic configuration or the second characteristic configuration, it is possible to simplify the cam-type linkage mechanism and the valve body mounting configuration. In addition, it is possible to provide a thermal power control device for a gas combustion device that can accurately adjust the thermal power required by the thermal power control operation tool.

In addition to any of the first to fourth feature configurations described above, the fifth feature configuration of the present invention includes:
An operating means is provided for operating the heating power adjusting operation tool to an ignition position when an ignition operating tool for igniting the burner is operated.
The click feeling imparting recess is provided in such a manner that the specific position in the thermal power adjustment moving range of the thermal power adjustment operation tool is different from the ignition position.

In other words, when the ignition operation tool for igniting the burner is ignited, the thermal power adjustment operation tool is operated to the ignition position, so that the burner is ignited satisfactorily with the amount of gas supplied to the burner set to an amount suitable for ignition. It will be possible.
Then, after the burner is ignited, the operation of the heating power adjustment operation tool to a specific position can be accurately performed by providing a click feeling for easily understanding the position of the heating power adjustment operation tool.

  If you add explanation, the specific position of the movement range for thermal power adjustment depends on the usage situation such as the position where the thermal power adjustment operating tool is frequently operated and the position where the thermal power adjustment operating tool needs to be accurately positioned for thermal power adjustment. Although the ignition position of the thermal power adjustment operation tool is determined as a position for causing the burner to be favorably ignited in the thermal power adjustment moving range, the specific position and the ignition position are different. However, after the burner is ignited, it is possible to accurately operate the thermal power adjustment operation tool to a specific position by giving a click feeling so that the position of the thermal power adjustment operation tool can be easily understood.

  In short, according to the fifth characteristic configuration of the present invention, in addition to the operational effects of the first to fourth characteristic configurations, it is possible to accurately operate the heating power adjusting operation tool to a specific position after the ignition of the burner. A thermal power control device for gas combustion equipment can be provided.
