DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation device provided with an operation knob exposed on a top plate of a housing or an upper surface of an operation plate, for example, when a liquid such as broth flows into the operation knob portion. The present invention relates to an operation device, an appliance operation device suitable for a certain heat appliance and the like, and a mounting auxiliary member used for these.

[0002]

2. Description of the Related Art In a device operating device of a type in which an operating knob is exposed on the upper surface of a top plate of a heating device, it is necessary to take measures against boiling over. For this purpose, for example, in the instrument operating device disclosed in Japanese Utility Model Laid-Open No. 57-116048, an annular convex portion protruding upward is formed on the periphery of the through hole for inserting the operating shaft portion of the top plate portion. An operation knob provided with a disk part having a larger diameter is connected to and integrated with the operation shaft part penetrating the through hole. Therefore, in the case of using the appliance operating device for a heating appliance, the boil-off that has flowed down to the top plate is blocked by the annular convex portion, and the gap around the outer periphery of the operating shaft portion is formed by the disk portion of the operating knob. Since it is shut off, the inconvenience of boiling over flowing into the inside of the appliance from the outer peripheral gap of the operation shaft portion is avoided.

On the other hand, as disclosed in Japanese Utility Model Laid-Open No. 59-4904, a decoration ring is provided concentrically with respect to an operation knob, and the operation knob is rotatably housed in a recess formed in the decoration ring. Some of the formats are: In this prior art device, since the axis of the operation shaft and the axis of the operation knob attached to the operation shaft are set horizontally, even if the operation knob is housed in the recessed portion, it runs along the front of the instrument. The penetrated broth or the like does not reach from the concave portion to the installation portion of the calorie adjusting device such as the gas cock.

However, the latter type of instrument operating device is
If it is used as it is on the top plate of a device such as a drop-in stove, it will not be possible to prevent the infusion of broth into the device, and it will be transmitted along the operating shaft and into the body of the gas cock and the calorie control switch. There's a problem. this is,
When the operation knob is disposed on the upper surface of the top plate in an upward position, the broth that enters from the gap between the operation knob and the decoration ring reaches the bottom of the decoration ring. In this case, as in the former case, the broth described above is used. Even if an annular convex portion protruding upward is formed on the periphery of the hole, the height of the annular convex portion cannot be set so large, and the broth and the like stored in the recessed portion eventually form the annular convex portion. This is because the air flows over the gap from the gap and reaches a calorie adjusting device such as a gas cock or a calorie switch disposed below the gap.

[0005]

[0008]

Means for Solving the Problems In order to solve the above-mentioned problems, the means for solving the above-mentioned problem according to the first aspect of the present invention is based on a decorative ring.
An annular convex portion (23) is provided over the entire periphery of the through hole of the bottom wall of the cylindrical portion (21) of (2), and the direction of the axis of the decorative ring (2) and the operation shaft portion is inclined toward the front side. Let the tubular part (21)
A relief hole (22) is provided in the lowermost part of the peripheral edge of the bottom wall or the lowermost part of the lower end of the body of the tubular part (21), and the relief hole is provided.
The position of (22) was set outside the calorie control device. "

According to this solution, even if the broth enters the cylindrical portion (21) of the decorative ring (2), the broth is kept at the lowermost portion of the peripheral edge of the bottom wall of the cylindrical portion (21). Alternatively, it is discharged from an escape hole (22) formed in the lowermost part of the lower end of the body.
The operation shaft of the calorie adjusting device penetrates the through hole in the bottom wall of the cylindrical portion (21), and there is a gap on the outer periphery thereof, but an annular convex portion (23) is provided on the periphery of the through hole. Therefore, there is no fear that boiling juice flows from the gap on the outer periphery of the operation shaft portion.

The broth that has reached the lowermost portion of the peripheral edge of the bottom wall of the cylindrical portion (21) or the lowermost portion of the lower end of the body portion flows down from an escape hole (22) provided outside the calorie adjusting device. Therefore, there is no fear that the boiling juice flows down to the calorie adjusting device. Particularly, in the above-mentioned solution, the direction of the axis of the decorative ring (2) and the axis of the operation shaft is inclined toward the near side, and the escape hole (22) is formed at the lowermost part of the peripheral edge of the bottom wall. Since it is provided at the lowermost part of the lower part of the barrel or the trunk, the boiling-up spilled in the cylindrical part (21) is biased toward the escape hole (22) side, and the boiling from the outer peripheral gap of the operation shaft part. Spills can be prevented more reliably.

According to a second aspect of the present invention, in the first aspect, the mounting mode of the decorative ring (2) is specified, and the means is that "the cylindrical portion (21) of the decorative ring (2) is A collar (24) is provided at the upper end of the cylindrical portion (21) so as to cover the peripheral edge of the circular opening. And a compression spring (B) between the bottom wall of the tubular portion (1).

[0012] In this case, even if the decorative ring (2) and the top plate are not fixed to each other, the collar portion (24) of the decorative ring (2) is formed by the repulsive force of the compression spring (B). The decorative ring (2) is easily attached because it is pressed against the peripheral edge of the opening. In this case, if the decorative ring (2) is mounted so as to be rotatable with respect to the top plate, the decorative ring (2) needs to be positioned. For this positioning, an engaging portion may be provided on the back surface of the collar portion (24) of the decorative ring (2) so as to engage with a part of the top plate in a detented state, and the bottom of the decorative ring (2) may be provided. The projecting piece protruding from the wall may be configured to engage with a part of the calorie adjusting device body in a non-rotating state, and other positioning means may be employed so that the decorative ring (2) can It is only necessary that the relationship be tied and even.

[0013] As defined in claim 3, in the solution of the invention of claim 2, "the decoration ring
(2) is configured to be fitted with a margin to the mounting portion of the top plate portion (3), and the distal end of the annular convex portion (23) is tightly rotatable relative to the operation shaft portion. In this case, it is possible to more reliably prevent the inconvenience of boiling spills, broth and the like having entered the cylindrical portion (21) from entering the inside of the operation shaft portion from the outer circumferential gap.

In this case, the decorative ring (2) including the fitting part of the opening of the top plate (3) and the decorative ring (2) is included.
Since there is a fitting margin in the direction along the plane of the top plate part (3) in all fitting parts of the top plate part (3) and the top part, the tip of the annular convex part (23) is Even if they are closely fitted in such a manner that they can be relatively rotated, there is no concern that the operability of the operation knob (1) will be impaired.
This is because even if there is a variation in concentricity or the like between the operating shaft portion and the fitting portion, the concentricity is absorbed by the fitting margin, and the tight fitting state between the operating shaft portion and the annular convex portion (23) is ensured. .

As defined in claim 4, claim 1
In the inventions of (1) to (3), a circular concave portion (18) that opens downward is formed in the disk portion (1a) of the operation knob (1),
(23), the leading end of which penetrates into the annular concave portion (18) '', the inflow such as boiling over from the outer peripheral gap of the operating shaft (11) causes the outer peripheral side wall of the annular concave portion (18) and the annular convex portion. Since the flow is blocked by both of the parts (23), the inflow of the spillover can be more reliably prevented.

In a preferred embodiment of the present invention, a first side wall that defines an opening and surrounds the shaft member, and a through hole through which the shaft member penetrates, is provided on the opposite side of the first side wall from the opening side. A partition wall to be closed, a second side wall extending from an edge of a through hole of the partition wall to the opening side, and a partition wall or a connecting portion between the partition wall and the first side wall, the opening being provided at the opening. Side and a hole communicating with the opposite opening side, the partition wall is provided with a height difference in the axial direction at least on the opening side, and when the opening side is a high side, the hole is At the bottom. "

In the apparatus employing this solution, there is provided a hole connecting the opening side and the opposite opening side, that is, a hole for discharging the liquid flowing into the opening to the opposite opening side.
This hole is provided with a partition wall or a partition wall closing the opening and the first wall.
The liquid that has flowed into the opening is discharged from the hole because it is provided at the connection portion with the side wall of the hole. At that time, since the partition wall has a height difference in the axial direction, the liquid flowing into the opening flows from the high-order portion to the lower portion of the partition wall under the action of the gravity line, that is, by its own weight. Then, when the liquid reaches the lowest part of the partition wall, there (the partition wall,
Alternatively, since a hole is provided in the partition wall and the first side wall), it is easily discharged to the opposite opening side through the hole. That is, the liquid that has flowed into the opening is easily guided by its own weight to the lowermost hole due to the height difference of the partition wall. There is a through-hole for the shaft member inside the opening, and this through-hole has a second side wall extending toward the opening, and when the opening is at a high level, liquid flows into the through-hole. If the height position to be used is the partition wall (or the partition wall and the first
(The connection portion with the side wall) is higher than the height position of the hole. Therefore, all of the liquid flowing into the opening passes through the through hole and is discharged from the hole without passing through the through hole. Therefore, the inconvenience that the liquid that has flowed into the opening is discharged to the side opposite to the opening through the hole and flows into the through hole is eliminated.

According to a sixth aspect of the present invention, there is provided a liquid crystal display device comprising: a first side wall that defines an opening and surrounds a shaft member; and a through hole through which the shaft member penetrates. A partition wall to be closed, a second side wall extending from an edge of a through hole of the partition wall to the opening side, and a partition wall or a connecting portion between the partition wall and the first side wall, the opening being provided at the opening. And a hole communicating between the side and the opposite side of the opening, and a vertical cross-sectional shape including the hole and the axis is not a line-symmetric shape with respect to the axis. According to this solution, since the partition wall is not axisymmetric with respect to the axis, the partition wall is formed substantially so as to have a height difference in the axial direction. Therefore, the liquid that has flowed into the opening is easily affected by the action of gravity in the direction of the gravitational line, that is, easily flows from the higher part to the lower part of the partition wall by its own weight. If the hole is positioned at the lowermost portion, the liquid flowing into the opening can be easily guided to the lowermost portion due to the height difference of the partition wall due to its own weight, similarly to the invention of claim 5. I will
Thus, the inconvenience that the liquid that has flowed into the opening does not flow into the through-hole, is discharged to the opposite side of the opening through the hole, and flows into the through-hole is eliminated.

According to a seventh aspect of the present invention, there is provided a partitioning wall which includes a through-hole and partitions the operation knob side and the control means side in the axial direction, and extends from the partition wall to the operation knob side. A first side wall formed so as to surround the shaft member, and a radially inner side of the first side wall and extending from the edge of the through hole of the partition wall to the operation knob side. A hole for communicating the operation knob side and the control means side is provided at the partition wall or at a connecting portion between the partition wall and the first side wall; The hole is located at a radial distance greater than the radial dimension defined by the outer shape of the control means on the same radial line about the axis. " With this solution, a liquid such as broth falls onto the operation knob,
Even if the liquid flows into the mounting auxiliary member or the liquid flows directly into the mounting auxiliary member, the disadvantage that the liquid reaches the control means through the through hole is eliminated. That is, the liquid that has flowed into the attachment assisting member is captured by the opening formed by the partition wall and the first side wall, and the hole provided in the partition wall (or the connection portion between the partition wall and the first side wall). From the control means. Since this hole is located at a radial distance larger than the radial dimension defined by the outer shape of the control means on the same radial line centered on the axis, even if liquid is discharged from the hole to the control means side. , Avoiding reaching the direct control means itself. The partition wall is provided with a through hole through which the shaft member penetrates and reaches the control means side. This through hole has a second side wall extending toward the knob side, and the knob side is referred to as a higher portion. Then, the height position at which the liquid flows into the through hole is relatively higher than the height position of the hole of the partition wall (or the connecting portion between the partition wall and the first side wall). Therefore, the liquid that has flowed into the mounting auxiliary member does not pass through the through hole and reach the control means itself through the through hole, and is discharged to the control means side that does not affect the control means through the hole. This allows
Even if the liquid flows between the operation knob and the mounting auxiliary member, the inconvenience of flowing into the through hole of the shaft member and reaching the control means is eliminated.

According to an eighth aspect of the present invention, the position of the hole in the state in which the operation plate is mounted is specified in the seventh aspect. Is provided corresponding to the lowermost portion in the vertical direction of the partition wall or the lowermost portion in the vertical direction of the connecting portion between the partition wall and the first side wall. " According to this solution, even if the operation device is mounted on the operation plate in the horizontal or inclined mounting position, the liquid flowing into the mounting auxiliary member can be easily utilized by using its own weight. At the hole. That is, since the hole for discharging the liquid is the lowest part of the partition wall (or the connecting portion between the partition wall and the first side wall), the liquid is affected in the direction of the gravitational line (vertical direction), that is, The hole can be easily reached by its own weight. Therefore, the disadvantage that the liquid reaches the control means through the through-hole is eliminated, as in the seventh aspect.

According to a ninth aspect of the present invention, the partition wall is specified in the eighth aspect. "The partition wall has a height difference in the axial direction at least on the operation knob side. ] That is. According to this solution, the partition wall is provided with a height difference in the axial direction so that the hole according to claim 8 is the lowest part of the partition wall (or the connecting portion between the partition wall and the first side wall). I did it. Thereby, when the present operating device is mounted on the operating plate, the present operating device is particularly preferable when the operating device is in a horizontal position, and the liquid flowing between the operating knob and the mounting assisting member is reduced by its own weight. It is easily led to the hole. For this reason,
The same disadvantage as the eighth aspect is solved.

According to a tenth aspect of the present invention, in claim 8, the sectional shape of the mounting auxiliary member is specified. "The mounting auxiliary member has a longitudinal section including the hole and the axis. The shape is not a line-symmetric shape with respect to the axis. " According to this solution, the cross-sectional shape of the mounting auxiliary member is set to be line-symmetric so that the hole according to claim 8 is the lowermost portion of the partition wall (or the connecting portion between the partition wall and the first side wall). This prevents the partition wall from being line-symmetrical with respect to the axis, so that the partition wall has a height difference in the axial direction.
Therefore, also in this means, the liquid is easily guided to the lowermost hole by its own weight, and the same disadvantages as in claim 8 are solved.

[0023]

As described above, according to the invention of the appliance operating device according to the first aspect, the boil-over that has entered through the gap between the operating knob and the decorative ring does not flow down to the calorie adjusting device, so that the calorific value is reduced. The inconvenience that the adjusting device is damaged by boiling can be eliminated. Also, as described above, the cylindrical portion (21)
The boiled spills stored in the boiler are biased toward the escape hole (22) side, so that the falling position of the broth is surely removed from the calorie control device.

According to the second aspect of the present invention, the decoration ring (2) is moved relative to the top plate by a spring interposed between the bottom wall of the decoration ring (2) and the operation knob. Since it is fixed, installation of the decorative ring (2) can be simplified.
According to the third and fourth aspects of the invention, the inconvenience of boiling over from the outer peripheral gap of the operating shaft can be prevented more reliably.

According to the fifth aspect of the present invention, since the partition wall is provided with a height difference and the hole is located at the lowermost portion, the liquid flowing into the opening can easily enter the hole by its own weight. Since the liquid is guided and discharged to the opposite opening side through the hole, the disadvantage that the liquid flows into the through hole is eliminated. According to the invention as set forth in claim 6, the vertical cross section including the hole and the axis is prevented from being line-symmetric with respect to the axis, so that the partition wall has a height difference substantially. Thus, the inconvenience that the liquid that has flowed into the opening flows into the through-hole is eliminated. Claim 7
According to the invention of the operating device described above, since the mounting auxiliary member and the hole for liquid discharge are provided in a predetermined manner, the liquid such as broth falls down to the operation knob and flows into the mounting auxiliary member, or the liquid directly flows to the mounting auxiliary member. Even when the liquid flows, the inconvenience that the liquid reaches the control means through the through hole is eliminated. According to the invention of the operating device according to claim 8, since the hole is positioned at the lowest part in the vertical direction so that the liquid can be guided to the hole by its own weight,
The disadvantage of the liquid reaching the control means through the through-hole is eliminated. According to the ninth aspect of the present invention, the partition wall has a height difference in the axial direction.
As before, the liquid is easily guided to the lowest hole, eliminating the disadvantage. According to the operation device of the tenth aspect, since the vertical cross-sectional shape including the hole and the axis of the mounting auxiliary member is not made to be line-symmetrical with respect to the axis, the height difference between the partition wall and the height of the partition wall can be substantially reduced. Thus, the liquid is easily guided to the lowermost hole as in the ninth aspect, and the inconvenience that the liquid reaches the control means through the through hole is eliminated.
