The detailed configuration will be described below.

A first plate-like body 32 that moves with the five virtues 12 is provided for the five virtues 12. The first plate-like body 32 has an annular plate shape in plan view. In plan view, the outer peripheral edge 32 a of the first plate-like body 32 substantially coincides with the inner peripheral edge 10 a of the opening 10, and the inner peripheral edge 32 d of the first plate-like body 32 is substantially the same as the outer peripheral edge 14 a of the burner body 14. Matching shapes.
The first plate-like body 32 protrudes outward from the outer peripheral edge 32a so that the upper surface 32c and the upper surface 11a of the top plate 11 are located in substantially the same plane in a state where the virtues 12 are located at the use position. It has a convex part 32b. And when the 1st plate-shaped body 32 moves toward the upper direction from the downward direction of the top plate 11, the convex part 32b of the collar part 33 provided toward the center P side from the inner periphery 10a of the opening part 10 is provided. It contacts the annular protrusion 45.

The virtues 12 are composed of a plurality of claw members 28. In this example, it is composed of six claw members 28. The claw member 28 includes a contact support portion 26 that contacts the object to be heated and supports the object to be heated, and a base portion 27 that is located on the top plate 11 side of the contact support portion 26 at the use position. . That is, the claw member 28 is substantially U-shaped.
The claw member 28 is formed as a plate-like body extending in the vertical direction (Z direction in FIG. 1A), and the claw member 28 is formed from the center P of the opening 10 (shown in FIG. 1C). Are arranged substantially evenly in the circumferential direction of the opening 10 so as to follow the radiation.

  As shown in FIG. 2, the tip end portion 26 a of the abutment support portion 26 of the claw member 28 is directed toward the center P side of the opening 10 in the use state of the virtues 12, and as shown in FIG. In the housed state, it is generally configured to be directed downward away from the top plate 11.

The first plate-like body 32 is provided with a rotation axis L of the claw member 28 whose axial direction is along the top plate surface in the spreading direction of the top plate 11 and along the tangential direction of the opening 10. It has been.
The rotation axis L is inserted into a portion on one end side of the base portion 27 of the claw member 28 (a portion on the center P side of the opening 10). Therefore, the claw member 28 can swing around the rotation axis L with respect to the first plate-like body 32.
The rotation axis L is provided closer to the center of the opening than the inner peripheral edge 10a of the opening 10 as shown in FIGS. Here, the opening center side from the inner peripheral edge 10a of the opening 10 means the inside of the range indicated by the arrow X2 in FIGS. 2 and 3, that is, the center P side of the opening 10.

  As a result, the claw member 28 is rotated around the rotation axis L arranged along the top plate 11 as shown in FIGS. 1 (a) and 1 (b) and FIGS. 2 and 3. The posture is freely changeable between the diameter-expanded posture (state shown in FIG. 2) and the diameter-reduced posture (state shown in FIG. 3) of the five virtues 12.

As described above, the posture change of the claw member 28 is caused by the link mechanism connected to the swinging end portion 30 of the claw member 28.
The claw member 28 takes a use posture and a storage posture corresponding to the use position and the storage position of the virtues 12, respectively, and the posture of the claw member 28 is the first plate-like body 32 and the second plate described above. The structure is determined by the spacing between the plate-like bodies 34, the posture of the link member 31, and the positional relationship between the rotation axis L of the claw member 28 and the claw member side pivot shaft 30 a of the link member 31. That is, the posture changing means referred to in the present application is mainly configured by these members and the linked configuration.

In order to facilitate understanding, first, the attitude of the claw member 28 -the distance between the first plate 32 and the second plate 34 -the attitude of the link member 31 -the rotation axis L of the claw member 28 and the link member It arranges and shows in order of the positional relationship with the claw member side pivot shaft 30a.
In the use state in which the virtues 12 shown in FIG. 2 are located at the use position and indicate the diameter-expanded posture, the claw member posture (the diameter-expanded posture) —the separation interval between the first plate-like body 32 and the second plate-like body 34 ( Proximity) -Position of the link member 31 (tilt posture in which the longitudinal direction is oblique) -Position relationship between the rotation axis L of the claw member 28 and the claw member side pivot shaft 30a of the link member 31 (claw with respect to the rotation axis L) The member side pivot shaft 30a is located on the substantially inner diameter side).

3, in the storage state in which the virtues 12 are located at the storage position and indicate the reduced diameter posture, the claw member posture (the reduced diameter posture) -the separation interval between the first plate body 32 and the second plate body 34 ( Remote)-Posture of link member 31 (vertical posture in which longitudinal direction is substantially vertical)-Positional relationship between rotation axis L of claw member 28 and claw member side pivot shaft 30a of link member 31 (relative to rotation axis L) The claw member-side pivot shaft 30a is located substantially on the lower side in the vertical direction).
Hereinafter, it demonstrates individually.
[Link mechanism]
When the claw member 28 is viewed around the rotation axis L, as shown in FIG. 2, the claw member 28 is positioned on the contact support portion 26 side as viewed from the rotation axis L, and the claw member 28 is viewed from the rotation axis L. A swing end portion 30 is provided on the opposite side of the swing portion 29. A link member 31 that determines the position of the rocking end portion 30 is connected to the swing end portion 30 via a claw member-side pivot shaft 30a. The other end of the link member 31 is connected to the second plate-like body side pivot shaft 37 provided on the second plate-like body 34 fixed to the burner 13 and then to the vertically moving plate 21.
As described above, the link member 31 takes an inclined posture in which the longitudinal direction is oblique when the first plate body 32 and the second plate body 34 are close to each other. The positional relationship between the rotation shaft L and the claw member-side pivot shaft 30a of the link member 31 is such that the claw member-side pivot shaft 30a is positioned on the substantially inner diameter side with respect to the rotation shaft L. As a result, in this use state (the state shown in FIG. 2), the claw member 28 is maintained in the use posture along the top plate 11 in the longitudinal direction, and the virtues 12 are maintained in the diameter-expanded posture.
On the other hand, the link member 31 takes a vertical posture in which the longitudinal direction thereof is in the vertical direction in the state where the first plate-like body 32 and the second plate-like body 34 are separated from each other, and the rotation axis L of the claw member 28 The positional relationship between the link member 31 and the claw member-side pivot shaft 30a is such that the claw member-side pivot shaft 30a is positioned substantially downward in the vertical direction with respect to the rotation axis L. As a result, in this storage state (the state shown in FIG. 3), the claw member 28 is maintained in the storage posture in which the longitudinal direction thereof is directed in the vertical direction, and the virtues 12 are maintained in the reduced diameter posture.

  Therefore, the link member 31 swings and changes the position of the swing end 30 of the claw member 28 around the rotation axis L, and the use posture in which the longitudinal direction of the claw member 28 is along the top plate 11 and the claw member It is switched between the storage postures in which the longitudinal direction of 28 is directed in the vertical direction. As a result, when the virtues 12 are in the diameter-expanded posture, the maximum outer diameter X1 of the virtues 12 can be made larger than the opening diameter X2 of the opening 10, and when the virtues 12 are in the contracted posture, the maximum outer diameter X1 of the virtues 12 is It can be made smaller than the opening diameter X2 of the opening 10.

Next, a description will be further given of the posture changing operation of the virtues 12 when the link member 31 moves between the use position and the storage position of the virtues 12 with reference to FIGS.
[Posture change due to movement between use position and storage position]

For example, in a state before cooking is started, the user of the gas stove operates a cooking start button (not shown).
By this operation, when the first electric motor 24 is started (for example, forwardly rotated), the rotation support shaft 22 is moved upward via the drive pulley 43 and the driven pulley 23, and the vertical movement plate 21 is moved upward. Moving.

At this time, the virtues 12 and the burner 13 move from the storage position shown in FIG. 3 to the intermediate position shown in FIG.
That is, as the up-and-down moving plate 21 moves upward, the second plate 34, the link member 31, the first plate 32, and the plunger 35 that are provided integrally with the burner body 14 include the opening 10. It moves from below to above the opening. At this time, the first plate-like body 32 is not restricted with respect to its upward movement. When the intermediate position is reached, the convex portion 32 b of the first plate-like body 32 comes into contact with the annular projecting portion 45 of the flange portion 33 of the opening 10.

  Between the storage position and the intermediate position, the plunger 35 provided integrally with the second plate-like body 34 works, and the distance between the first plate-like body 32 and the second plate-like body 34 is kept large. The As a result, the rocking end 30 of the claw member 28 is positioned between the rotation shaft L and the second plate-like body-side pivot shaft 37, and the rocking end 30 is on the lower side with respect to the rotation shaft L. The oscillating portion 29 is located above the rotation axis L. As a result, the claw member 28 takes the storage posture (the posture shown in FIG. 5) in which the longitudinal direction thereof is in the vertical direction, and the virtues 12 are maintained in the reduced diameter posture (the posture shown in FIG. 5).

  Thereafter, when the virtues 12 are moved from the intermediate position shown in FIG. 5 to the use position shown in FIG. 4, the first plate-like body 32 is the flange portion of the opening 10 in the moving direction (the arrow Z direction in FIG. 5). Abutting on the annular projecting portion 45 of 33, its rise is restricted. On the other hand, the 2nd plate-shaped body 34 moves to the top-plate 11 side with the raising / lowering of the up-and-down moving plate 21 and the burner 13. As a result, the separation distance between the second plate-like body 34 and the first plate-like body 32 becomes smaller against the pushing force of the plunger 35.

Accordingly, the swing end 30 of the claw member 28 is positioned on the lateral side of the rotation shaft L from the position between the rotation shaft L and the second plate-like body side pivot shaft 37, and the swung portion 29 is It is positioned on the side opposite to the swing end 30 with respect to the rotation axis L. As a result, the position of the claw member 28 is changed from the stowed posture (the posture shown in FIG. 5) in which the longitudinal direction is directed in the vertical direction to the usage posture (the posture shown in FIG. 4) in which the longitudinal direction is directed along the top plate 11. Thus, the virtues 12 change the posture from the reduced diameter posture (the posture shown in FIG. 5) to the enlarged diameter posture (the posture shown in FIG. 4).
At this time, the swinging end portion 30 is slidably moved along the inner peripheral edge 10a of the opening portion 10, and its posture change is guided.

As described above, with the movement of the virtues 12 from the storage position to the use position, the virtues 12 are appropriately changed in posture from the reduced diameter posture to the enlarged diameter posture.
In addition, when the virtues 12 and the burner 13 move from the use position to the storage position, the above-described functional parts perform the operations opposite to the operations described so far, so that the virtues 12 and the burner 13 are used. In accordance with the shift from the position to the storage position, the virtues 12 change the posture from the diameter-expanded posture to the reduced-diameter posture.

[Cover]
In the gas stove of the present embodiment, when the virtues 12 and the burner 13 are in the storage position, a closed position (position shown in FIG. 3) that closes the opening 10 and a separated position that deviates from the lower position of the opening 10 (FIG. 6 and a disengagement position (position shown in FIGS. 6 and 7) that is disengaged from the opening 10 is provided with a cover 38 that can be repositioned. Hereinafter, the configuration and operation of the lid portion 38 will be described with reference to FIGS.

[Horizontal movement of the lid]
As shown in FIGS. 6 and 7, a lid rotating shaft 39 that extends downward from the lower surface of the lid portion 38 with respect to the lid portion 38, and a second electric motor that rotates the lid portion rotating shaft 39 about its axis. A motor 40 is provided. The lid rotating shaft 39 is provided at a position eccentric from the center P of the opening 10 (shown in FIG. 1C) in the direction along the top plate 11. Thus, the second electric motor 40 rotates the lid rotation shaft 39 around the axis, so that the lid 38 is positioned below the opening 10 (position shown in FIG. 7) and the opening 10. It is moved between a position deviated from the lower position (for example, the position shown in FIG. 6).
The lid rotation shaft 39 is provided with a projection 39a (shown in FIG. 2) on the outer peripheral portion thereof, and in the vicinity of the projection 39a, the lid rotation shaft 39 is provided around the axis of the lid rotation shaft 39. A position detection sensor 42 for detecting the rotational position of the protrusion 39a accompanying the rotation is provided. The second electric motor 40 controls the drive amount of the second electric motor 40 based on the detection signal of the position detection sensor 42. Thus, the 2nd electric motor 40, the rotation axis 39 for lid parts, and the rotation position detection sensor 42 function as a lid part moving means.

[Moving the lid in the vertical direction]
The lid rotating shaft 39 is configured to be rotatable around the axis, and the lid rotating shaft 39 is configured to be vertically extendable or movable in the vertical direction.
Accordingly, the first electric motor 24 is driven to move the rotation support shaft 22 upward in the state where the lid portion 38 is located below the opening 10 (position shown in FIG. 7). 13 is moved in the direction from the bottom toward the lid portion 38, and the virtues 12 are brought into contact with the lower end portion 38 a of the lid portion 38, whereby the lid portion 38 is brought into a closed position (position shown in FIG. 3) for closing the opening 10. Can be moved. In addition, a retraction portion 38b that retreats inward in the radial direction is formed on the outer peripheral edge of the lid portion 38, and the retraction portion 38b is fitted to the annular protrusion 45 of the flange portion 33 of the opening 10 from below. Thus, the opening 10 is closed by the lid 38. Thereby, the top surface of the gas stove can be made into a substantially horizontal plane by the top surface 11a of the top plate 11 and the top surface 38c of the lid portion 38, and the aesthetics and the cleanability are enhanced.
Therefore, in this example, the movement of the lid portion 38 in the vertical direction (the direction indicated by the arrow Z in FIGS. 2 and 3) moves the virtues 12 and the burner 13 to the use position (position shown in FIG. 2) and the storage position (FIG. 3). The first electric motor 24 that is moved between the first electric motor 24 and the second electric motor 24 is also used to simplify the structure.

[Another embodiment]
(1) In the above embodiment, the description has been given of the configuration in which the virtues 12 are brought into contact with the lower end portion 38 a of the lid portion 38 and push the lid portion 38 upward, but for example, the burner body 14 contacts the lower end portion 38 a of the lid portion 38. It may be configured to contact and push the lid portion 38 upward. In this case, the burner body 14 may have a shape or the like in which a part of the burner body 14 protrudes toward the lid portion 38.

(2) In the above embodiment, the burner 13 may be configured to integrally include a flame detection sensor that detects the state of the flame in the burner body 14.

(3) In the above embodiment, the claw member 28 has a shape along the vertical direction (the direction of the arrow Z in FIGS. 2 and 3), but is not limited to a plate shape, and has been used as a conventional five virtues 12. Any shape can be used as long as it has a different shape. For example, the contact support portion 26 and the base portion 27 may be integrally formed in a rod shape.

(4) When the top plate 11 is made of a relatively fragile glass, the flange 33 is necessary, but when the top plate 11 is made of a relatively strong metal plate, the top plate 11 is omitted. 11 may be subjected to necessary processing so that the function of the flange 33 is also used.

(5) The movement of the lid portion 38 is not limited to a rotational movement, and may be, for example, a sliding movement (parallel movement).

  The gas stove according to the present invention can be effectively used as a highly convenient gas stove that can be stably supported by the Gotoku after the Gotoku and the burner move to the use position.
