  By the way, with a gas stove, spilled broth or the like spilled during cooking may flow or accumulate on the top plate against the user's intention. There is a problem that the liquid on the top plate easily enters the apparatus from the vicinity of the operation unit.

  For example, in the configuration in which the rotation operation is performed by the operation knob 19 as in Patent Document 1, the shaft 20 serving as the rotation center needs to be held rotatably in the apparatus, and thus the shaft 20 and the shaft 20 can be rotated. There will be a considerable gap between the bearing portion to be held. Because of such a configuration, when a liquid such as boiled juice that has flowed on the top plate flows down from the vicinity of the operation knob 19 through the shaft 20 into the apparatus, it enters further through the gap. There is a risk of affecting the equipment driven by the shaft 20.

  The present invention has been made in order to solve the above-described problem, and a shaft member is disposed across the upper side and the lower side of the housing unit, and is rotated by an operation unit provided on the upper end side of the shaft member. In the gas stove having a configuration capable of performing the above, there is provided a configuration capable of effectively preventing liquid from entering the lower end side of the shaft member through the shaft member.

The gas stove of the present invention is
A housing part constituting the outer surface part of the stove;
A shaft member that is configured to extend at least partially from the upper surface side of the housing portion to the inside and to be rotatable about a predetermined rotation axis, and to extend in the direction of the rotation axis;
An operation portion that is provided on one end side of the shaft member and at least a part of which is disposed on the upper side of the upper surface portion of the housing portion, and that allows a predetermined rotation operation to rotate the shaft member;
A housing part comprising an insertion hole part into which the other end side of the shaft member is inserted, and an internal partial region configured as a gas passage region;
A bearing portion disposed so as to at least partially fill the insertion hole portion around the shaft member;
An adjusting unit that is arranged inside the housing unit and increases or decreases the flow rate of the gas in the housing unit according to the rotation of the shaft member when the shaft member rotates in accordance with the predetermined rotation operation;
A cover plate that is provided with an insertion hole portion through which the shaft member is inserted and is arranged so as to protrude from the outer peripheral surface of the shaft member in a flange shape, and is configured to cover the bearing portion on the upper side of the bearing portion;
A seal member that is disposed on at least one plate surface side of the cover plate and seals between the insertion hole portion of the cover plate and the shaft member;
A fixing portion for fixing the cover plate and the seal member to the shaft member;
A structure in which the bearing part is assembled to the housing part and is fixed to the connection body in a form that covers the connection body from above, and the shaft member is inserted, and the region that covers the bearing part is viewed from above. a covering plate engaging hole portion continuous to the lower surface is formed, possess,
The bearing portion is formed with an engagement protrusion that is configured to protrude upward and to be engaged in a state of being inserted into the engagement hole.
When the cover plate and the engagement hole are projected onto a virtual horizontal plane perpendicular to the vertical direction, the projection position of the engagement hole is more than the projection position of the outer edge of the cover plate on the virtual horizontal plane. Will also be inside .

In the present invention, a shaft member is arranged so as to extend from the upper surface portion side to the inner side of the housing portion, and the shaft member can be rotated by an operation portion provided above the upper surface portion of the housing portion. It has a configuration. Therefore, this configuration is advantageous in applications or environments where such operations from above are desired. Further, according to the present invention, a flange-shaped cover plate is provided on the upper side of the bearing portion that receives the shaft member, and the shaft member is inserted into the cover plate so as to cover the bearing portion. Because of such a configuration, even if liquid enters the shaft member from the outside of the housing, the liquid is received on the upper surface of the cover plate. Therefore, the flow of the liquid in the form transmitted through the shaft member is suppressed below the cover plate, and the liquid can be reliably suppressed from flowing into the vicinity of the bearing portion. In addition, since the seal member is provided to seal between the insertion hole portion of the cover plate and the shaft member, the liquid received by the cover plate flows down to the bearing portion side through the gap between the shaft member and the cover plate. Can be surely prevented. According to this configuration, since the cover plate is arranged in a form that covers from above the coupling body in which the bearing portion is assembled to the housing portion, the hermeticity of the housing portion is further improved. Furthermore, since the bearing portion is attached in a form that engages with the cover plate, the bearing portion can be stably disposed in the housing portion with a simple holding structure. In such a simplified configuration, there is a concern that liquid such as boiled juice may enter from the engagement portion where the cover plate and the bearing portion engage, but the above configuration is in a virtual horizontal plane perpendicular to the vertical direction. When the cover plate and the engagement hole portion are projected, the projection position of the engagement hole portion is on the inner side of the projection position of the outer edge portion of the cover plate in a virtual horizontal plane. That is, even if the liquid received by the cover plate flows down from the cover plate, it is difficult for the liquid to be directly applied to the engaging portion.

  In the present invention, the direction of the rotation axis of the shaft member may be a direction inclined with respect to the vertical direction. And the upper surface part of a cover board may incline with respect to a horizontal direction, and may be arrange | positioned.

  According to this configuration, the rotation operation can be performed around the inclined rotation axis. Furthermore, since the upper surface portion of the cover plate is inclined with respect to the horizontal direction, when the liquid that has flowed down through the shaft member is received by the cover plate, the liquid is dropped to a region outside the bearing portion. It becomes easy. Therefore, for example, a state in which the liquid received by the cover plate wraps around the back side of the cover plate and propagates through the lower shaft member is less likely to occur.

  In the present invention, the seal member may be disposed only on the lower surface side of the upper surface and the lower surface of the cover plate.

  According to this configuration, it is possible to reduce the number of parts while ensuring the sealing performance between the shaft member and the cover plate. Further, the liquid can be received in a simplified form on the upper surface side of the cover plate.

  In the present invention, a suppression plate that suppresses heat transfer may be provided between the housing portion and the cover plate so as to cover the cover plate.

  According to this configuration, the suppression plate that suppresses heat transfer can be used for the suppression of liquid entry. That is, it is possible to realize a configuration capable of producing both the effect of suppressing heat transfer and the effect of suppressing the entrance of liquid while suppressing an increase in the number of components.

The insertion hole 25A is configured as a hole extending in the direction of the rotation axis C, and the upper side is open. And the bearing part 27, the adjustment part 29, etc. are accommodated in the inside of 25 A of insertion holes.

  The covering plate 39 is fixed to the connection body 24 in a form that covers the connection body 24 in which the bearing portion 27 is assembled to the housing portion 25 from above. The covering plate 39 is made of, for example, a metal material, and is fixed to the upper end portion of the accommodating portion 25 by a connecting member such as a screw in a form that at least partially closes the insertion hole portion 25A. The covering plate 39 is formed with a through-hole portion through which the shaft member 23 is inserted, and the shaft member 23 is inserted through the cover plate 39 so as to be inserted into the through-hole portion. Engagement hole portions 39A and 39B extending from the upper surface to the lower surface are formed as through-hole portions in a region covering the bearing portion 27 in the cover plate 39, respectively.

  The bearing portion 27 is disposed around the shaft member 23 so as to at least partially fill the insertion hole portion 25A. A through-hole portion 27C is formed near the center of the bearing portion 27, and the shaft member 23 is inserted through the through-hole portion 27C. A slight gap is formed between the through-hole portion 27C and the shaft member 23 so that the shaft member 23 can be rotated while the outer peripheral surface is supported by the through-hole portion 27C. It has become. The bearing portion 27 is formed with engaging protrusions 27A and 27B that engage with engaging holes 39A and 39B formed in the cover plate 39.

I am doing. The bearing portion 27 is fixed to the cover plate 39 with such an engagement structure.

  The adjustment unit 29 is disposed inside the storage unit 25, and increases or decreases the flow rate of gas in the storage unit 25 according to the rotation of the shaft member 23 when the shaft member 23 rotates in accordance with the rotation operation with respect to the operation unit 21. It is a part that functions to The adjusting unit 29 includes a spindle 82, a rotating unit (rotating closure) 84, a seal ring 86, and the like.

  As shown in FIG. 9, a plate-like member 65 projecting in the rotational radius direction is fixed at an intermediate position of the shaft member 23, and between the plate-like member 65 and the covering plate 39, a support portion 67 and a spring member are provided. 61 is arranged. The spring member 61 is urged so as to continuously push up the support portion 67 along the direction of the shaft member 23, and the plate-like member 65 and the shaft member 23 are always moved in the axial direction by the support portion 67. An urging force to the side (the upper side in the axial direction) is generated. Therefore, in a state where no external operation is performed on the operation unit 21, the shaft member 23 is maintained at the upper position shown in FIG. 9 by such an urging force. On the other hand, when the operation part 21 and the shaft member 23 are pushed down against such an urging force, the shaft member 23 moves downward. When the shaft member 23 moves to a lower position to some extent, further downward movement is restricted while applying an upward elastic force.

  In the adjusting portion 29 shown in FIG. 9, the rotating portion 84 (rotating closing member) meshes with the engaging portion 23B formed at the lower end portion of the shaft member 23 when the shaft member 23 is in the lower position. In such a meshing state, the rotating portion 84 (rotating closure) rotates in conjunction with the rotation of the shaft member 23. That is, when the operation unit 21 is rotated after the operation unit 21 is pressed, the rotation unit 84 (rotary closing member) rotates. The rotating portion 84 (rotating closure) is a portion that adjusts the gas flow rate in the accommodating portion 25, and is provided between the path A1 and the path A2 shown in FIG. 9 when the rotating portion 84 is at a predetermined initial position. The open / close portion is closed so that gas does not flow in the accommodating portion 25. As the rotating part 84 rotates in the predetermined direction from the initial position, the opening degree of the opening / closing part provided between the path A1 and the path A2 increases, and the gas flow rate increases.

  The spindle 82 provided on the lower side of the shaft member 23 extends in the direction of the rotation axis C so as to penetrate the inside of the rotation portion 84, and the tip portion (lower end portion) faces the magnet electromagnetic valve 88. Yes. The spindle 82 moves downward in conjunction with the downward movement of the shaft member 23, and causes the magnet electromagnetic valve 88 to be in an open state at a position where the meshing portion 23B meshes with the rotating portion 84. The spindle 82 and the rotating portion 84 are sealed with a seal ring 86.

  As shown in FIGS. 8 and 9, the cover plate 31 is provided with an insertion hole portion 31 </ b> A through which the shaft member 23 is inserted, and is disposed so as to protrude from the outer peripheral surface of the shaft member 23 in a flange shape, above the bearing portion 27. It arrange | positions by the structure which covers the bearing part 27 in the side. The upper surface portion 31B of the cover plate 31 is disposed so as to be inclined with respect to the horizontal direction. Specifically, the cover plate 31 is in an inclined state in which the front side is lower than the rear side. The fixing rings 35 and 37 (fixing portions) function to fix the cover plate 31 and the seal member 33 to the shaft member 23.

  As shown in FIGS. 7 and 8, a fixing ring 35 configured as an E ring is fixed to the shaft member 23 on the upper surface portion 31 </ b> B side of the cover plate 31, and the cover plate 31 is fixed by the fixing ring 35. The movement to the upper side in the axial direction is restricted. Further, as shown in FIGS. 8 and 9, a rubber seal member 33 configured as a shaft packing is provided in contact with the lower surface portion of the cover plate 31. A metal saw 38 is stacked below the seal member 33, and a fixing ring 37 configured as an E ring is fixed to the shaft member 23 below the saw 38. That is, the stacked body of the cover plate 31, the seal member 33, and the countersunk 38 is fixed to the shaft member 23 by being vertically moved by the upper and lower fixing rings 35 and 37. The seal member 33 functions to seal between the insertion hole 31 </ b> A of the cover plate 31 and the shaft member 23.

  In the first operating device 10A configured as described above, when the cover plate 31 and the engagement hole portions 39A and 39B are projected on a virtual horizontal plane orthogonal to the vertical direction, the engagement hole portion is projected on the virtual horizontal plane. The projection positions 39 </ b> A and 39 </ b> B are configured to be inside the projection position of the outer edge portion of the cover plate 31.

  Furthermore, in this configuration, as shown in FIG. 5, a suppression plate 41 that functions as a heat shield plate is provided between the housing 2 and the cover plate 31 on the upper side of the cover plate 31. The suppression plate 41 is disposed between the cover plate 31 and the inclined upper surface portion 90 (FIGS. 1 to 4), and suppresses heat transfer with a configuration that covers the cover plate 31. In the configuration of FIG. 5, the shaft member 23 is disposed so as to be inserted into the hole 41 </ b> A formed in the suppression plate 41, and the diameter of the hole 41 </ b> A of the suppression plate 41 is larger than the diameter of the cover plate 31. It is getting smaller. When the hole 41A and the cover plate 31 are projected on a virtual plane orthogonal to the rotation axis C, the position of the outer edge portion of the cover plate 31 is entirely outside the position of the hole 41A. Also, in the horizontal direction orthogonal to the vertical direction, the position of the outer edge portion of the cover plate 31 is on the outer side than the position of the hole portion 41A.

  As described above, in the gas stove 1 described above, the shaft member 23 is arranged so as to extend from the upper surface side (top plate 2A) of the housing 2 to the inner side, and the top plate 2A (upper surface portion) is disposed with respect to the shaft member 23. ) Can be rotated by the operation unit 21 provided on the upper side. Therefore, this configuration is advantageous in applications or environments where such operations from above are desired. Further, a flange-like cover plate 31 is provided on the upper side of the bearing portion 27 that receives the shaft member 23, and the shaft member 23 is inserted into the cover plate 31 so as to cover the bearing portion 27. Because of such a configuration, even if a liquid such as boiled juice that has flowed through the top plate 2A passes through the shaft member 23 and enters the inside of the housing portion 2, the liquid can be received on the upper surface of the cover plate 31. become. Therefore, on the lower side of the cover plate 31, the liquid flowing down the shaft member 23 is suppressed, and the liquid flowing into the vicinity of the bearing portion 27 can be reliably suppressed. In addition, since the seal member 33 is provided to seal between the insertion hole portion 31 </ b> A of the cover plate 31 and the shaft member 23, the liquid received by the cover plate 31 is between the shaft member 23 and the cover plate 31. It can be reliably prevented from flowing down to the bearing portion 27 side through the gap.

  Further, the direction of the rotation axis C of the shaft member 23 is a direction inclined with respect to the vertical direction, and the upper surface portion 31B of the cover plate 31 is arranged inclined with respect to the horizontal direction. According to this configuration, the rotation operation can be performed around the inclined rotation axis C. Further, since the upper surface portion 31B of the cover plate 31 is arranged to be inclined with respect to the horizontal direction, when the liquid flowing down through the shaft member 23 is received by the cover plate 31, the liquid is removed from the bearing portion 27. It will be easier to drop it to a detached area. Therefore, for example, a state in which the liquid received by the cover plate 31 wraps around the back side of the cover plate 31 and propagates through the shaft member 23 therebelow is less likely to occur.

  Further, the seal member 33 is disposed only on the lower surface side of the upper surface and the lower surface of the cover plate 31. According to this configuration, it is possible to reduce the number of parts while ensuring the sealing performance between the shaft member 23 and the cover plate 31. Further, the liquid can be received in a simplified form on the upper surface side of the cover plate 31.

  In addition, a suppression plate 41 that suppresses heat transfer is provided between the housing unit 2 and the cover plate 31 so as to cover the cover plate 31. According to this configuration, the suppression plate 41 that suppresses heat transfer can also be used for suppressing liquid entry. That is, it is possible to realize a configuration capable of producing both the effect of suppressing heat transfer and the effect of suppressing the entrance of liquid while suppressing an increase in the number of components.

  Further, a covering plate 39 is provided, and the covering plate 39 is fixed to the connecting body 24 and covers the connecting body 24 (a structure in which the bearing portion 27 is assembled to the housing portion 25) from above. The member 23 is configured to be inserted. Further, the cover plate 39 is formed with engagement holes 39A and 39B extending from the upper surface to the lower surface in a region covering the bearing portion 27. The bearing portion 27 is formed with engaging protrusions 27A and 27B that are configured to protrude upward and engage with each other while being inserted into the engaging holes 39A and 39B. When the cover plate 31 and the engagement hole portions 39A and 39B are projected on a virtual horizontal plane orthogonal to the vertical direction, the projection positions of the engagement hole portions 39A and 39B are the outer edges of the cover plate 31 on the virtual horizontal plane. It is the structure which becomes an inner side rather than the projection position of a part.

  Thus, since the covering plate 39 is arranged in a form that covers the connecting body 24 (the structure in which the bearing portion 27 is assembled to the housing portion 25) from above, the sealing performance of the housing portion 25 is further improved. Furthermore, since the bearing portion 27 is attached so as to engage with the cover plate 39, the bearing portion 27 can be stably disposed in the housing portion 25 with a simple holding structure. In such a simplified configuration, there is a concern that liquid such as boiled juice may enter from the engagement portion where the cover plate 39 and the bearing portion 27 engage, but the above configuration is a virtual one that is orthogonal to the vertical direction. When the cover plate 31 and the engagement hole portions 39A and 39B are projected on the horizontal plane, the projection position of the engagement hole portions 39A and 39B is on the inner side of the projection position of the outer edge portion of the cover plate 31 on the virtual horizontal plane. ing. That is, even if the liquid received by the cover plate 31 flows down from the cover plate 31, it is difficult for the liquid to be directly applied to the engaging portion.
