Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an operation position display device for gas appliances such as a gas table and a gas water heater.

[0002]

[Prior art]

 Among gas appliances such as gas tables and gas water heaters, the operation of igniting and extinguishing them by push-button operation is now the mainstream, but push-button operation is more common than rotary knobs and slide-type levers. Since it is difficult to discriminate the operation position, conventionally, there is a display sign that facilitates discrimination. Therefore, conventional operation position display devices of this type are disclosed in, for example, Japanese Utility Model Laid-Open No. 61-86602 (hereinafter referred to as Conventional Example 1) and Japanese Utility Model Laid-Open No. 4-10253 (hereinafter referred to as Conventional Example 2). There are things that have been done.

In the conventional example 1, an ignition button and a fire extinguisher button are arranged side by side, and a knob for adjusting the heat power is provided above these buttons, and an operating position of the ignition button is provided between the knob and the button. Is provided, and a display plate that interlocks with the ignition button via the drive lever and the contact portion is provided, and the display portion of the display plate faces the inside of the window hole. When it is not pressed, the display part of the display plate is lifted through the engaging piece with the abutment part integrated with the drive lever.For example, the lower surface of the black-colored display part faces the window hole and the ignition button is pressed. At times, the abutment portion and the engagement piece of the display plate are disengaged from each other and the display portion is lowered by its own weight. For example, the upper surface of the display portion colored red is opposed to the window hole.

The conventional example 2 is composed of a single operation knob, and a display window hole is formed at a proper position on the front surface of the operation knob, and one end is fixed to a support cover on the back side of the window hole. The other end of the substantially strip-shaped and flexible indicator plate is attached, the indicator plate is provided so as to interlock with the operation knob, and the indicator for indicating that the indicator plate is at the burning position of the burner The main structure is colored red, which means that it is burning, and the use of a rack-and-pinion mechanism as a means for linking the display with the operation knob is also shown.

[0005]

[Problems to be solved by the device]

 In the prior art example 1, an ignition button and a fire extinguishing button are provided separately, and when the ignition button is pressed for ignition and when the fire extinguishing button is pressed for extinguishing the fire button, the ignition button returns to its original position. It is rotationally displaced in conjunction with (forward) and return (reverse) operations.

Therefore, the operation button moves from the extinguishing position to the ignition position by the first pressing operation (when the burner is ignited), returns to the ignition position by releasing the pressing, and is locked by the second pressing operation (when the burner extinguishes). When applied to a so-called push or push type in which the lock at the ignition position is unlocked and the pressure is released to return from the ignition position to the fire extinguishing position, a stroke to the ignition position is required. Since there is no movement and the gap between the display part and the ignition button must be made large, there is a need to make a large gap between the ignition button and the display plate, making it difficult to bring the display part of the display plate close to the window hole. However, there is a drawback that the position cannot be clearly displayed.

In addition, when there is an error in the play gap between the abutting portion and the engaging piece of the display plate due to long-term use, or when the display plate moves poorly due to adhesion of dust, boiling water, etc., In particular, when the fire extinguishing display is performed, the display plate rotates by its own weight, so the position of the display part cannot be accurately determined, and the middle part of the display part, that is, the boundary part between black and red faces the window hole. In some cases, it may not be possible to determine whether to display ignition or extinguishing, and the correct display cannot always be obtained.

In the conventional example 2, when the operation knob is pushed to perform ignition and extinguishing operations, the display plate slides while deforming along the back surface of the window hole, and when the operation knob is in the non-combustion position, the display plate The non-colored part faces the display window and indicates that the operating knob is in the non-burning position.When the operating knob is pressed to the burning position, the display plate moves in conjunction with this and the colored part It indicates that the operating knob is at the burning position, facing the display window.

Therefore, when it is applied to a push type or a push type, if the conventional example 2, for example, FIG. 6 (B) is the ignition position, the colored portion of the display plate strikes the operating knob at the ignition position. When the ignition position is shown in FIG. 6 (B), the colored portion of the display plate retreats from the window hole to make the display impossible.

Further, since the display plate slides along a long stroke of fire extinguishing → ignition → ignition while deforming along the back surface of the window hole each time due to its flexibility, it may be used frequently, and thus the display plate may be used early. The display is damaged and lacks in durability, and if the display board is caught on something, it will not be able to move and it will stop halfway and the display position will not be accurately determined. It is something that cannot be surely obtained.

In both of the above-mentioned conventional examples 1 and 2, the display member and the valve main body portion must be integrally assembled. Therefore, it is difficult to control the dimensions of the front panel and the knob or its operating member, which necessitates the construction of highly accurate components and the need to provide a large gap between the combined parts, etc. It is not something that can be used, but lacks in practicality.

[0012] In view of the above problems of the prior art, the present invention aims at providing an operation position display device for a gas appliance which has a simple structure for accurately displaying the correct position of an operation button.

[0013]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the operation position display device of the gas appliance of the present invention is, for example, as shown in the drawings corresponding to the embodiment, the operation button 1 is pressed from the extinguishing position a by the initial pressing operation. After passing through the ignition position b, it moves to the ignition position c, and when it is released, it returns to the ignition position b and is locked, and when it is pressed again, the lock at the ignition position b is released, and when it is released, the ignition position b is extinguished. Returning to a. In the operating device for a gas appliance, an operation button 1 which is pivotally moved in the front-rear direction by a predetermined angle around the pivot 2 as a fulcrum, and an operation button 1 and a pivot hole 4 which are interlocked with each other through the guide hole 3 It is composed of an actuating member 5 which rotates in a vertical direction at a fixed angle with a fulcrum as a fulcrum, and a display tongue 6 which is attached to the actuating member 5 and displays the position of the operation button 1. The display tongue 6 faces the inside of the display window 7, Are the extinguishing position a of the operation button 1 to display the window 7, the main feature to be displayed by distinguishing between up to ignition position c from the ignition position b.

In relation to the above-mentioned specific invention, the guide hole 3 is formed in a substantially V shape, and the display tongue 6 moves at a high speed from the extinguishing position a to the ignition position b, and from the ignition position b to the ignition position c. Then, on the upper surface of the actuating body 5, the guide portion 8 into which the base end mounting portion of the display tongue 6 can be linearly inserted from the front and the engaging hole 9 formed in the base end mounting portion of the display tongue piece 6 are formed. It is also characterized in that an engagement protrusion 10 for fitting the above is provided.

[0015]

[Action]

In response to this movement, the actuation body 5 is forcibly rotated in the vertical direction with the pivot 4 as a fulcrum, and the correct position of the operation button 1 is always reliably displayed by the display tongue 6.

In addition, since the guide hole 3 is formed in a substantially V shape and the moving speed of the display tongue 6 from the fire extinguishing position a to the ignition position b is increased to increase the rate of change, the display tongue 6 is displayed. The ignition and ignition positions are displayed sensitively and reliably.

Furthermore, when attaching the display tongue 6 to the actuation body 5, the base end attachment portion of the display tongue 6 is simply inserted linearly along the guide portion 8 of the actuation body 5 to engage the engagement hole 9 thereof. The engaging tongue can be fitted and engaged with the convex portion 10, so that the display tongue piece 6 can be easily attached to the actuation body 5.

The structure is provided with a headed engagement protrusion 10 having a triangular cross-section that fits and engages with the engagement hole 9.

The actuating body 5 is mounted by pivotally supporting the pivot shaft 4 on the bearing portion 17 of the mounting frame body 12 and by freely inserting the guide pin 16 into the guide hole 3 of the operation button 1. The operation tongue 1 and the guide hole 3 are interlocked with each other, and the display tongue 6 is moved up and down by rotating the pivot 4 as a fulcrum in a vertical direction by a predetermined angle.

Reference numeral 6 denotes a display tongue for displaying the position of the operation button 1, which is made of a strip-shaped thin plate and is fitted to the engaging projection 10 having the head of the actuating body 5 at the base end mounting portion 6 a thereof. An engaging hole 9 having notches at four corners that can be fitted is provided, and a display portion 18 colored in red or the like for indicating ignition and ignition is provided at an end portion of the tip hanging piece portion 6b. In the embodiment, the ignition position b to the ignition position c of the operation button 1 is displayed in a colored portion such as red, and the extinguishing position a is displayed in a non-colored background color.

The display tongue piece 6 has its base end attachment portion 6a attached to the actuation body 5, and the tip end display portion 6b faces the inside of the display window 7 of the operation button 1 so as to freely slide up and down to display. When the tongue piece 6 moves up and down, the display window 18 displays the extinguishing position a of the operation button 1 and the ignition position b to the ignition position c on the display portion 18 in a distinguishable manner. In the embodiment, a transparent scattering mirror 19 is provided in the display window 7 of the operation button 1 so that the position display of the operation button 1 by the tip display portion 18 of the display tongue 6 can be performed clearly through the scattering mirror 19. I have to.

The guide hole 3 is formed in a substantially dogleg shape in which the inclination angle of the starting end side 3 a is larger than the movement locus of the guide pin 16 of the actuation body 5 and the inclination angle of the terminal end side 3 b is small. The moving speed of the display tongue 6 is increased from the extinguishing position a to the ignition position b by a steep inclination of the starting end side 3a, and is slowed from the ignition position b to the ignition position c by a gentle inclination of the end side 3b, so that the guide hole 3 is formed. The rate of change of the moving speed of the display tongue 6 on the starting side 3a and on the ending side 3b is different.

The insertion protrusion 8a of the guide portion 8 is formed in a gate shape and guides the base end mounting portion 6a of the display tongue piece 6 through, and the slanted protrusions 8b on both sides are displayed tongue pieces. 6, both ends of the base end mounting portion 6a are supported and guided obliquely upward to guide the engagement hole 9 to the upper part of the engagement protrusion 10 so that the engagement hole 9 automatically moves to the engagement protrusion 10. When engaged, the notch recesses 11 provided on both sides of the base end mounting portion fit into the slanted protrusions 8b.

In the above configuration, when the burner is ignited, the operation button 1 at the fire extinguishing position a shown in the solid line in FIG. 1, the dotted line in FIG. 2 and in FIG. 1) and pivotally displaces to the ignition position c through the ignition position b shown in FIG. 1 and FIG. 2 and the substantially intermediate ignition position b shown in FIG. Is interlocked via the substantially V-shaped guide hole 3, and while the operation button 1 is moving from the fire extinguishing position a to the ignition position b, the inclination angle of the starting end side 3a of the substantially U-shaped guide hole 3 moves the guide pin 16. Since it is larger than the locus, the actuating body 5 is quickly lifted upward with the pivot 4 as a fulcrum via the guide pin 16 and is lifted for a long distance. It moves quickly upward and the colored portion of the display portion 18 is moved to the inside of the display window 7 of the operation button 1. Since the inclination angle of the terminal end side 3b of the substantially V-shaped guide hole 3 is smaller than the movement locus of the guide pin 16, the tip tongue piece 6b of the display tongue piece 6 is displayed. Slowly move it to reliably display that the operation button 1 is in the ignition operation on the colored portion.

After that, when the pressing is released, the operation button 1 is automatically returned to the ignition position b shown in the solid line of FIG. 2 and FIG. It is rotationally displaced and set to the ignition position b. At this time, the operation button 1 returns from the ignition position c to the ignition position b, and the display tongue 6 slowly moves downward along the terminal end side 3b of the substantially V-shaped guide hole 3, but the tip end. The colored portion of the display portion 18 is still located inside the display window 7 of the operation button 1 to reliably indicate that the operation button 1 is at the ignition position (burner combustion position) b 2.

Next, when extinguishing the burner, the operation button 1 at the ignition position b shown in the solid line in FIG. 2 and in FIG. 7 is pushed forward (counterclockwise in the figure) by the finger rest 11 thereof. , The lock of the operation button 1 at the ignition position b is released. After that, when the pressing is released, the operation button 1 is automatically rotationally displaced rearward (clockwise in the drawing) to the fire extinguishing position a shown in the solid line in FIG. 1, the dotted line in FIG. 2 and in FIG. The burner extinguishes the fire. With the return of the operation button 1 to the fire extinguishing position a, the tip hanging portion 6b of the display tongue 6 is rapidly lowered by the starting end side 3a of the substantially dog-legged guide hole 3 and the colored portion of the tip display portion 18 is removed. The operation button 1 is moved to the outside of the display window 7 and the background color of the tip display portion 18 is surely displayed to indicate that the operation button 1 is at the fire extinguishing position a.

When attaching the display tongue 6 to the actuating body 5, the base end attaching portion 6a of the display tongue 6 is linearly inserted through the insertion protrusion 8a of the guide portion 8, and the base attaching portion 6a is located on both sides. The slanted ridge 8b guides the slanted ridge 8a upward, and when the slanted ridge 8b reaches the upper portion of the engagement ridge 10, the engagement hole 9 is automatically engaged with the engagement ridge 10. At this time, since the cut-in concave portion 11 of the base end mounting portion 6a fits into the slanted protrusion 8b, it does not interfere.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and it is needless to say that the present invention can be implemented in various modes without departing from the gist of the present invention. . For example, in the present embodiment, the one applied to each operation button of the gas table with a grill is shown, but it can also be applied to the operation button for the hot water supply and stop of the hot water supply of the gas water heater, and in the present embodiment, the operation button Although the position indication is distinguished by the background color of the display tongue and the colored part, it is not limited to coloring as long as the position indication can be distinguished.
