  By the way, when it is set as the structure which forms a through-hole in the front panel attached to the front side of a heating cooker main body, and makes a rotation operation type rotation operation part protrude ahead through this through-hole, the outer peripheral part of a rotation operation part It is desirable that the diameter of the inner peripheral wall of the through hole is made somewhat larger than the diameter of the through hole, and the rotation operation portion is disposed away from the inner peripheral wall of the through hole. By doing so, it is possible to prevent the rotation operation unit from always contacting the inner peripheral wall of the through hole, and it is easy to stably attach the front panel even if a manufacturing error or the like occurs.

  However, in the configuration in which the rotation operation unit is separated from the inner peripheral wall of the through hole in this way, if this space is completely made into a space, the space will be easily noticeable when viewed from the front side by the user. There's a problem. In particular, if the front panel is mounted in a state where the center of the rotation operation portion and the center of the through hole are slightly shifted due to an assembly error of each component or a slight warp in the manufacturing process, the rotation operation portion There is a problem in that the gap formed between the through holes is also deformed and becomes an uneven shape instead of being completely annular, which impairs the aesthetic appearance. In addition, since the plurality of rotation operation parts pass through the through holes of the panel, gaps having different shapes are formed, and there is a possibility that the aesthetic appearance may be impaired.

  The present invention has been made to solve the above-described problems, and in a configuration in which the rotation operation unit protrudes forward through a through hole formed in the front panel of the heating cooker body, the rotation operation unit is penetrated. It aims at providing the structure which is easy to suppress generating large cyclic | annular space between them, spacing apart from the inner peripheral wall of a hole to some extent.

The present invention is a cooking device in which an outer peripheral surface is configured in a cylindrical shape and a rotation operation unit that rotates around a predetermined rotation axis is disposed on the front side of the cooking device body,
A holding unit that is provided on the front side of the heating cooker body and rotatably holds the rotation operation unit;
A front panel that is formed with a through hole, covers the front side of the holding unit, and is attached to the heating cooker body in a configuration in which the rotation operation unit is inserted into the through hole;
An overhang member that is incorporated in the inner peripheral wall of the through hole formed in the front panel and is disposed around the outer peripheral portion of the rotation operation unit that is inserted into the through hole;
With
The extension member has an inner edge portion located on the rotation operation portion side smaller in diameter than the inner diameter of the through hole, and the inner edge portion is closer to the outer periphery portion of the rotation operation portion than the inner peripheral wall of the through hole. It is characterized by having a structure that protrudes toward the surface.

In the first aspect of the invention, the overhang member is incorporated in the inner peripheral wall of the through hole formed in the front panel, and the overhang member has an inner edge portion located on the rotation operation portion side with a diameter larger than the inner diameter of the through hole. The inner edge portion is smaller than the inner peripheral wall of the through hole and protrudes toward the outer peripheral portion of the rotation operation portion.
Since it is configured in this way, the gap formed between the inner peripheral wall of the through hole and the rotation operation portion is filled by the projecting member, and the gap between the inner peripheral wall of the through hole and the rotation operation portion is filled. The presence of the gap can be removed from the user's consciousness. Therefore, it is possible to effectively suppress a decrease in aesthetics due to the presence of a large annular space and its bias.

In the invention of claim 2, the entire circumference of the inner edge portion of the projecting member is arranged so as to project from the inner peripheral wall of the through hole toward the outer peripheral portion side of the rotation operation portion.
According to this configuration, since the approach to the through-hole can be suppressed in any direction over the entire circumference of the rotation operation unit, it is possible to suppress the bias in any direction of the rotation operation unit. The decrease can be prevented more reliably.
In addition, the gap formed between the inner peripheral wall of the through hole and the rotation operation portion is filled all around the rotation operation portion so that the inner edge portion of the overhang member can be visually recognized in an annular shape as a whole. Become. In other words, the gap space is reduced over the entire circumference of the rotation operation portion, and the visually recognizable shape of the overhanging member becomes a good-looking ring, so that the beauty can be further enhanced.

According to a third aspect of the present invention, a groove part cut out in the circumferential direction of the through hole is formed on the inner peripheral wall of the through hole, and the overhanging member is attached to the groove part around the rotation operation part, and at least one of the inner edge parts. The part can be moved in a direction along the front surface of the front panel while maintaining a state in which the portion protrudes from the inner peripheral wall of the through hole toward the outer peripheral side of the rotation operation unit.
In this configuration, a highly effective projecting member can be assembled with a simple configuration in which the groove is cut out on the inner peripheral wall of the through hole.
In addition, the overhang member is arranged in a state where a margin for movement is ensured to some extent so that the overhang member can move in a direction along the front surface of the front panel. In other words, even if the rotation operation part is slightly displaced for some reason, the extension member is adjusted to match that position, so that the assembly failure caused by the position of the rotation operation part and the extension member being out of alignment. It becomes easy to suppress. In addition, when the rotational operation portion is slightly displaced, the projecting member is also displaced so as to match the displacement, so that it is possible to more reliably suppress the conspicuous space at the time of the displacement.

Moreover, by rotating the rotation operation part 6a in one rotation direction in such a protruding state, the heating power of the corresponding right cooking unit 4a can be increased, and conversely, the rotation operation part 6a is changed to the other By rotating in the direction of rotation, it is possible to increase the heating power of the corresponding right cooking unit 4a. Further, when the front surface portion 41 is pressed in the projecting state indicated by the two-dot chain line 6 ′, the retracted state indicated by the solid line is restored, and at this time, the right stove portion 4a is extinguished.

  The rotation operation unit 6b performs ignition, extinguishing, and heating power adjustment of the left cooking unit 4b, the rotation operation unit 6c performs ignition, extinguishing, and heating power adjustment of the small cooking unit 4c, and the rotation operation unit 106a Ignition, extinguishing, and heating power adjustment of the grill 3 are performed. These are different in object, but the basic structure and function are the same as those of the rotation operation unit 6a.

  The front panel 20 functions as a decorative panel that constitutes a part of the front part (upper right upper region) of the heating cooker 1, and has a locking claw 50 (FIG. 4A) with respect to the heating cooker body 1 a. 5) and the like. In addition, the front panel 20 should just be detachably mounted | worn with the front side of the heating cooker main body 1a, and a mounting structure is not specifically limited.

  In this configuration, as shown in FIG. 3, the three rotation operation parts 6a, 6b, 6c are held by the holding part 8 that forms a part of the heating cooker body 1a so as to be rotatable and movable in the front-rear direction. The holding unit 8 includes, for example, a front surface portion (not shown) that faces the back surface (rear surface) of the front panel 20, and the rotation operation portions 6a, 6b, and 6c protrude forward from the front surface portion. . Note that the holding structure in the holding unit 8 (that is, the rotation operation units 6a, 6b, and 6c can be rotated, and the rotation operation units 6a, 6b, and 6c are switched to the protruding position and the retraction position each time the rotation operation units 6a, 6b, and 6c are pressed. For example, a known mechanism in a built-in stove may be used. And the front panel 20 is arrange | positioned by the structure which covers the front side of such a holding | maintenance part 8. FIG.

  As shown in FIGS. 1, 2, 4 </ b> A, 4 </ b> B, and 6, three through holes 22 are formed in the front panel 20. As shown in FIGS. 1 and 2, among these through holes 22, the rotation operation part 6a is inserted into the first through hole 22a, the rotation operation part 6b is inserted into the second through hole 22b, and the third The rotation operation portion 6c is inserted into the through hole 22c. As described above, the front panel 20 is arranged to cover the front side of the holding unit 8, and the heating cooker body has a configuration in which the rotation operation units 6 a, 6 b, 6 c are inserted into the through holes 22 a, 22 b, 22 c. It is attached to 1a.

  Then, as shown in FIGS. 4A, 4C, and 6, three ring members 30 (first ring member 30a and second ring member 30b are incorporated into the through holes 22a, 22b, and 22c. , A third ring member 30c) is disposed. Any of the ring members 30 a, 30 b, 30 c is incorporated in the inner peripheral wall 23 a of each through hole 22 formed in the front panel 20, and is arranged around the outer peripheral portion of the rotation operation unit 6 inserted into each through hole 22. It becomes the composition which is done.

  In this configuration, the rotation operation unit 6a and the other rotation operation units 6b and 6c have the same configuration. Therefore, hereinafter, as a representative example of the rotation operation unit 6, the first rotation operation unit 6 a will be described as an example. The through hole 22a and the other through holes 22b, 22c, and 122a have the same configuration, and the ring member 30a, the other ring members 30b and 30c, and the ring member disposed around the rotation operation unit 106a. The configuration of (not shown) is the same. Therefore, in the following, as a representative example of the through hole 22, the through hole 22 a will be described as an example, and as a representative example of the ring member 30, the ring member 30 a will be described as an example.

  The rotation operation unit 6a is arranged on the front side of the heating cooker main body 1a as shown in FIGS. 1 and 2, and as shown in FIG. 3) and is held rotatably (see also FIGS. 5B and 7). For example, the rotation operation unit 6a is formed in a columnar shape as a whole, and the outer surface (outer peripheral surface) of the outer peripheral portion 43 is configured as a smooth, substantially cylindrical surface. Further, the front surface portion 41 of the rotation operation unit 6a is configured as a flat surface whose outer surface is orthogonal to the direction of the rotation axis G, for example.

  As shown in FIG. 8, the through hole 22 a is configured as a hole that penetrates the front panel 20 configured in a plate shape in the thickness direction, and the inner peripheral edge viewed from the front side as shown in FIG. The shape and the shape of the inner peripheral edge viewed from the back side as shown in FIG. 6A are also substantially circular. As shown in FIG. 8, the rotation operation portion 6a is inserted into the through-hole 22a, and the rotation operation portion 6a can be moved back and forth in the inserted state.

  Further, as shown in FIG. 8, the diameter D1 of the outer peripheral surface of the rotation operation portion 6a is the diameter of the inner peripheral wall 23a in the through hole 22a (more specifically, the innermost portion of the inner peripheral wall 23a of the through hole 22a). The diameter) is smaller than D3, and when these are viewed from the front, the entire region of “the portion that can be disposed forward of the through hole 22a in the rotation operation portion 6a” is disposed in the opening region of the through hole 22a. It is like that. More specifically, in the direction along the front surface 20a of the front panel 20, the “region of the portion that can be disposed in front of the through hole 22a in the rotation operation portion 6a” does not become outside the opening region of the through hole 22a. It has a configuration.

  Then, as shown in FIG. 8, the ring member 30a is incorporated in the inner peripheral wall 23a of the through hole 22a formed in this way, and surrounds the periphery of the outer peripheral portion 43 of the rotation operation portion 6a inserted into the through hole 22a. Be placed. The ring member 30a has an annular ring shape as shown in FIGS. 9A, 9B, and 9C, and is made of, for example, a resin material. Moreover, the friction coefficient of the surface of the inner edge part 32 in the ring member 30a is smaller than the friction coefficient of the surface of the inner peripheral wall 23a in the through hole 22a, thereby improving the slidability.

  As shown in FIGS. 9A and 9B, a pair of projecting portions 34 and 34 projecting in the lateral direction are formed on the outer peripheral portion of the ring member 30a. As shown in FIGS. Positioning in the circumferential direction is achieved by fitting the portions 34 and 34 into a pair of holes 27 and 27 formed in the groove 25a, so that the ring member 30a does not rotate in the circumferential direction. Further, as shown in FIGS. 8 and 9, the inner edge portion 32 that can come into contact with the rotation operation portion 6a is formed in a stepped shape at a position on the one side in the thickness direction (position closer to the front end) in the inner peripheral portion of the ring member 30a. In this inner peripheral portion, the inner diameter of the rear portion 33 is slightly larger than the inner diameter D <b> 2 of the inner edge portion 32 than the inner edge portion 32. In this configuration, the ring member 30a is restricted from moving rearward by fitting and fixing the annular restricting portion 29 into the rear portion 33. In this configuration, the plate-like member 21b is fixed to the back side of the plate-like panel main body 21a that constitutes most of the front panel 20, and the groove 25a is constituted by the panel main body 21a and the plate-like member 21b. Yes. A part of the plate-like member 21 b is the restricting portion 29.

  As shown in FIG. 8, in the ring member 30a, the diameter D2 of the inner edge portion 32 located on the rotation operation portion 6a side is smaller than the inner diameter D3 of the through hole 22a. It is slightly larger than the diameter D1 of the outer peripheral surface of 6a. And the inner edge part 32 has the structure which protruded cyclically | annularly toward the outer peripheral part 43 side of the rotation operation part 6 rather than the inner peripheral wall 23a of the through-hole 22. As shown in FIG. Since the ring member 30a is configured in this way, a gap formed between the inner peripheral wall 23a of the through hole 22a and the rotation operation portion 6a is filled, and the inner peripheral wall 23a and the rotation operation portion 6a are closed. It becomes difficult to produce a large annular space between them. Therefore, it is possible to effectively suppress a decrease in aesthetics due to the presence of a large annular space and its bias.

  Particularly in this configuration, as shown in FIG. 7A, the entire circumference of the inner edge portion 32 of the ring member 30a always protrudes toward the outer peripheral portion 43 side of the rotation operation portion 6a rather than the inner peripheral wall 23a of the through hole 22a. Arranged in a different configuration. According to this configuration, since the approach to the through-hole 22a can be suppressed in any direction over the entire circumference of the rotation operation unit 6a, it is possible to suppress the deviation of the rotation operation unit 6a in any direction, and consequently, due to the deviation. It is possible to more reliably prevent a decrease in aesthetics.

  Further, as shown in FIG. 7A, the gap formed between the inner peripheral wall 23a of the through hole 22a and the rotation operation portion 6a is filled all around the rotation operation portion 6a, and the ring member 30a The inner edge portion 32 can be visually recognized in an annular shape as a whole. That is, the gap space is reduced over the entire circumference around the rotation operation unit 6a, and the visually recognizable shape of the ring member 30a becomes a good-looking ring, so that the beauty can be further enhanced.

  Further, in this configuration, as shown in FIGS. 7B and 8, a groove portion 25a cut out in the circumferential direction of the through hole 22a is formed in the inner peripheral wall 23a of the through hole 22a. The ring member 30a is attached to the groove portion 25a around the rotation operation portion 6a, and the size of the cylindrical inner peripheral surface formed in the groove portion 25a is the outer peripheral surface of the ring member 30a facing the inner peripheral surface. It is slightly larger than the size. Then, as shown in FIG. 7A, the ring member 30a is moved to the front panel 20 while maintaining the entire circumferential direction of the inner edge portion 32 projecting toward the outer peripheral portion 43 side of the rotation operation portion 6a from the inner peripheral wall 23a. It is possible to move slightly in the direction along the front surface 20a.

  According to this configuration, the highly effective ring member 30a can be assembled with a simple configuration in which the groove portion 25a is cut out by the inner peripheral wall 23a. In addition, the ring member 30a is arranged with a certain degree of movement margin so that the ring member 30a can move in a direction along the front surface 20a of the front panel 20. That is, even if the rotation operation portion 6a is slightly displaced for some reason, the ring member 30a is adjusted to match the position, and therefore the assembly caused by the position of the rotation operation portion 6a and the ring member 30a being out of alignment. It becomes easy to suppress defects. In addition, when the rotational operation unit 6a is slightly displaced, the ring member 30a is also displaced so as to match the displacement, so that it is possible to more reliably suppress the conspicuous space from conspicuous at the time of displacement.
