The S pole and the N pole are set for convenience and may be reversed.

  As shown in FIG. 6, when the operation unit 3 is arranged at a predetermined position on the top plate 2 in a predetermined direction, the magnetic flux of the main magnetic pole 35 in the operation unit is caused by the main magnetic flux penetrating the rotation center position 26 up and down. The magnetic force that acts to maintain the operation unit 3 in the vertical direction (vertical posture) acts, and the force that the operation unit main magnetic pole 35 attempts to position at the position of the main magnetic flux. As a result, the operation unit 3 has its operation unit main magnetic pole 35 positioned immediately above the main magnetic flux forming magnetic pole 61, and the position in plan view is maintained. In this state, even if a force acts on the operation unit 3 in the horizontal direction and slides on the top surface of the top plate 2, a magnetic force is applied to return the operation unit 3 to a predetermined position.

For example, the second predetermined distance may be the same as the first predetermined distance. In the first embodiment, the neodymium magnet as the click feeling imparting magnetic pole 62 is arranged in such a direction that the S pole is positioned on the upper side and the N pole is positioned on the lower side. The S pole and the N pole are set for convenience and may be reversed. The click feeling imparting magnetic pole 62 may be fixed to either the lower surface of the top plate 2 or the stove body 10 or may be fixed to another member. In the first embodiment, the click feeling imparting magnetic pole 62 is fixed to the substrate 60.

  When the operation unit 3 rotates, the magnetic attractive force acting between the operation unit rotation detection magnetic pole 36 and the click feeling imparting magnetic pole 62 changes every predetermined angular interval (60 ° in the first embodiment). . Thereby, a click feeling can be given to the operation unit 3 at every predetermined angular interval. Further, the rotation angle of the operation unit 3 in a plan view is maintained by the magnetic attractive force acting between the operation unit rotation detection magnetic pole 36 and the click feeling imparting magnetic pole 62. Thereby, even when a vibration occurs due to an earthquake or the like, the rotation angle of the operation unit 3 is maintained, and the operation unit 3 is prevented from rotating unless operated by the user.

  As shown in FIG. 6, a magnetic detection unit 63 that detects magnetic flux from the operation unit rotation detection magnetic pole 36 is provided on the lower surface side of the top plate 2. In the first embodiment, as shown in FIG. 8, as a magnetic detection unit 63, a 3 mm × 2 mm Hall element is 8 in distance (third predetermined distance) from the center of the main magnetic flux forming magnetic pole 61 in plan view. Two are provided at positions that are 30 ° apart from each other at a position 5 mm away from the direction in which the magnetic pole 62 for giving a click feeling is provided. Note that the number (two or more) of magnetic detection units 63 and the third predetermined distance are not particularly limited, and are not limited to Hall elements, and may be other magnetic detection elements such as magnetic detection resistors.

  When the operation unit 3 rotates, the magnetic detection unit 63 detects the magnetic flux from the operation unit rotation detection magnetic pole 36. The distance between the operation unit rotation detection magnetic pole 36 and the magnetic detection unit 63 is small or large. The magnitude of the magnetic flux detected by the magnetic detection unit 63 changes depending on (that is, depending on the rotation angle of the operation unit 3). By the rotation operation of the operation unit 3 as described above, the magnitude of the magnetic flux from the operation unit rotation detection magnetic pole 36 detected by the two magnetic detection units 63 is changed, respectively, and a control command for heating power control is sent to the heating control unit. Can be given to.

  Further, when the operation unit 3 in a predetermined position is slid rearward on the top plate 2 as indicated by an arrow A in FIG. 2, the operation unit rotation detection magnetic pole 36 detected by the two magnetic detection units 63. It is detected that the magnitude of the magnetic flux from each has changed, and the operation unit 3 has been slid. By such sliding movement of the operation unit 3, a control command for switching the ignition / extinguishing of the combustor 11 can be given to the heating control means, and the combustor 11 can be ignited or extinguished.

  As described above, the operation unit 3 that is slid rearward from the predetermined position returns to the predetermined position due to the magnetic force generated by the main magnetic pole 35 in the operation unit and the main magnetic flux forming magnetic pole 61.

Absent. For this reason, even if it is a case where the temperature of the top plate 2 rises, it is suppressed that a user touches the top plate 2 and feels hot.

  Further, in the gas stove 1 of the present invention, the operation unit 3 has the operation unit main magnetic pole 35 magnetically coupled to the main magnetic flux when used, and is installed at a predetermined position on the top surface of the top plate 2, and when not used, the operation unit 3 By pulling 3 away from the predetermined position, the magnetic coupling is released and the operation unit 3 can be removed from the top 2. That is, the operation unit 3 can be detachably provided on the top surface of the top plate 2. Thereby, when cleaning the upper surface of the top plate 2 when not in use (especially wiping and cleaning), the operation unit 3 does not get in the way, and the upper surface of the flat top plate 2 can be cleaned, thereby improving the ease of cleaning.

  Moreover, in 1st embodiment, as shown in FIG. 7, the lower surface 33 of the casing 32 of the operation part 3 is a convex curved surface which protrudes below. In the first embodiment, the lower surface 33 of the portion that becomes the vertical axis 31 (that is, the center of the operation unit 3 in plan view) is located at the lowest position, and the lower surface 33 is located at the upper side as it goes in the radially outward direction. Yes. At the outer edge, the angle formed by the lower surface 33 with respect to the horizontal direction is 0.75 °.

  As described above, the lower surface 33 of the casing 32 of the operation unit 3 has a convex curved surface, so that the contact surface between the lower surface 33 of the casing 32 and the upper surface of the top plate 2 becomes a part rather than the entire lower surface 33 of the casing 32. The contact area is small. Thereby, even if it is a case where the temperature of the top plate 2 rises, the calorie | heat amount transmitted from the top plate 2 to the operation part 3 is reduced, and it is suppressed that the operation part 3 becomes hot. Further, since the contact area between the lower surface 33 of the casing 32 and the upper surface of the top plate 2 is reduced, the friction when the operation unit 3 rotates is small, and the operation unit 3 rotates smoothly.

  In addition, the lower surface 33 of the casing 32 may not be such a convex curved surface, for example, may be a flat surface.

  Moreover, in 1st embodiment, as shown in FIG. 7, the upper surface 34 of the casing 32 of the operation part 3 is a concave curved surface dented below. In the first embodiment, the upper surface 34 of the portion that becomes the vertical axis 31 is positioned at the lowest position, and the upper surface 34 is positioned upward as it goes in the radially outward direction.

  In this way, by making the upper surface 34 of the casing 32 of the operation unit 3 a concave curved surface, the user does not operate by gripping the side surface of the operation unit 3, but operates while pressing the upper surface 34 of the operation unit 3 with a finger. When the part 3 is rotated, it becomes difficult for the finger to fall off from the outer edge of the upper surface 34, so that the operability is improved and the usability is improved.

  In addition, the upper surface 34 of the casing 32 may not be such a concave curved surface, for example, may be a flat surface or a convex curved surface.

  Moreover, in 1st embodiment, in order to suppress that the operation part 3 is heated by the stove burner 11 and a temperature rises, the stove burner 11 is provided in the back side rather than the center of the top-back direction of the top plate 2. FIG. As a result, the burner opening 20a of the top plate 2 is shifted rearward from the normal position so as to be close to the exhaust port 20b, and the width of the top plate 2 between them is shortened, and the strength of this portion may be reduced. . Therefore, in the first embodiment, as shown in FIG. 5, the reinforcing member 7 is provided in a portion between the burner opening 20 a and the exhaust port 20 b of the plate portion 21. In addition, the opening corresponding to the exhaust port 20b of the lower plate 4 is formed larger than the exhaust port 20b of the plate portion 21, and the reinforcing member 7 and the lower plate 4 do not interfere with each other.

  In the first embodiment, the reinforcing member 7 is configured by a reinforcing bar made of a channel material having a U-shaped cross section, as shown in FIG. 5C. However, the reinforcing member 7 is not easily bent such as an angle material or an H-shaped material. It may be a reinforcing bar and is not particularly limited. A concave groove 70 is formed in the outer surface of the web piece of the reinforcing member 7 so as to be recessed along the longitudinal direction and accommodate the adhesive 71.

  The adhesive 71 accommodated in the concave groove 70 adheres to the lower surface of the plate portion 21, and the reinforcing member 7 is fixed to a portion of the plate portion 21 between the burner opening 20 a and the exhaust port 20 b. Thereby, the intensity | strength and rigidity of the part between the opening 20a for burners of the board part 21 and the exhaust port 20b improve, and it is hard to break and it becomes difficult to bend.
