The fixed-side support member (shaft) 56 made of a cylindrical body extending in the vertical direction is provided.

  Further, as shown in FIG. 1A, a movable side support cylinder (holder) 53 that is fitted on the outer side of the fixed side support member 56 and is held so as to be movable up and down, and an upper end of the movable side support cylinder 53, Even when the bottom position of the cooking utensil 2 placed on the Gotoku 12 (FIG. 2) fluctuates in the vertical direction by following the vertical movement of the cooking utensil 2, the bottom surface of the cooking utensil 2 is always on the bottom surface. An abutting body (heat collecting plate) 51 configured to abut is provided.

  Furthermore, it is arranged on the lower surface side of the contact body 51 in such a manner as to be thermally coupled to the contact body 51, and is integrated with the contact body 51 to follow the vertical movement of the moving side support cylinder 53. A thermistor (temperature detection element) 57 for detecting the temperature of the cooking utensil 2 is provided so as to move up and down.

  In addition, a cover protection cylinder 63 is provided which covers the moving side support cylinder 53 from the upper end to the vicinity of the lower end concentrically through a predetermined space. Note that the lower part of the covering protection cylinder 63 is a small diameter part 63a having a smaller diameter than the upper part, and the inner diameter of the small diameter part 63a is outside the large diameter part 53b of the moving side support cylinder 53. The dimensions are approximately the same as the diameter.

  In addition, a protruding portion 73 is provided on the upper end side of the fixed-side support member 56 so as to protrude outward in the radial direction. In the first embodiment, a washer 55, which is a ring-shaped separate member, is fitted on the lower side of the bowl-shaped portion to form an overhanging portion.

  Further, at the uppermost position of the movable support cylinder 53 in the vertically movable range, the overhanging portion 73 comes into contact with the movable support cylinder 53 and further moves the movable support cylinder 53 upward. A small-diameter portion 53 a to be regulated is provided in the moving side support cylinder 53.

  In the temperature detection apparatus 1 for a stove according to the first embodiment, two strips are provided on the outer periphery of the fixed portion 70 of the fixed-side support member 56 at a predetermined interval in the axial direction of the fixed-side support member 56. The fixing groove 71 is formed so as to go around the outer periphery of the fixed portion 70, and the fixing convex portion 72 included in the fixing means 77 is fitted into the fixing groove 71, whereby the fixing side support member 56 fixed parts 70 are positioned and attached to the fixing part of the stove body (not shown).

In the first embodiment, a fixing means made of a wire is used as the fixing means 77, and the fixing means 77 itself is configured to function as a fixing convex portion 72 that fits into the fixing groove 71. Yes.
Thus, when the fixing means 77 is formed of a wire rod, the fixing means 77 itself functions as the fixing convex portion 72 that fits into the fixing concave groove 71, so that the configuration is simplified and the manufacturing cost is reduced. Therefore, it is possible to provide the temperature detection device 1 for a stove that is excellent in economic efficiency.

  Further, in the temperature detection device for a stove according to the first embodiment configured as described above, the overhanging portion 73 comes into contact with the uppermost position in the range in which the movable side support cylinder 53 can move up and down, and the movable side support is supported. The dimension of the inner peripheral edge of the small-diameter portion 53a that restricts further upward movement of the cylinder 53 is a dimension obtained by adding a little clearance to the outer diameter dimension of the cylinder constituting the fixed-side support member 56. It becomes possible.

  As a result, even when a lateral force is applied to the contact body 51, “rattle” occurs between the movable side support cylinder 53 and the fixed side support member 56, and the contact body 51 is inclined. It can suppress and prevent that, and can contact the contact body 51 appropriately with the bottom face of a cooking utensil.

  In addition, since the fixing groove 71 is formed over the entire outer periphery of the fixed-side support member 56, this restricts the direction of the fixed portion 70 in plan view (that is, the periphery of the fixed portion 70). It is possible to position the fixed portion 70 of the fixed-side support member 56 to the fixed portion of the stove main body while avoiding that the position in the direction is limited).

  Therefore, the fixed-side support member 56 can be securely fixed and held on the fixing portion of the stove body in a predetermined posture.

  Here, like the conventional temperature detection device shown in FIGS. 6 and 7, the protrusion 103b is formed on the guide tube 103 (corresponding to the fixed side support member 56 in the temperature detection device 1 for a stove according to the first embodiment of the present invention). When the temperature detection device is manufactured, the guide tube 103 is inserted into the small diameter portion of the two-step inner peripheral surface of the cylindrical support 102, and the flange portion of the guide tube 103 is provided. In order for 103a to be positioned above the small diameter portion of the two-step inner peripheral surface of the cylindrical support body 102, the guide cylinder 103 is moved from the upper side of the cylindrical support body 102 to 2 of the cylindrical support body 102. It is necessary to insert it into the small diameter portion of the stepped inner peripheral surface. And since the projection part 103b is provided in the lower end side of the guide cylinder 103, it is necessary to make the internal diameter of the small diameter part of the two step-shaped inner peripheral surface of the cylindrical support body 102 larger than the outer diameter of the projection part 103b. Between the guide tube 103 and the small-diameter portion of the two-step inner peripheral surface of the support body 102, the dimension corresponding to the difference between the outer diameter of the projection 103b and the outer diameter of the guide tube 103 is greater than or equal to There will be a gap. Then, when this stove is used, when a horizontal force is applied to the contact body 101 when the stove is used, the cylindrical support body 102 that supports the contact body 101 is inclined, and the contact is made. The body 101 does not properly come into contact with the bottom surface of the cooking utensil such as a pan, and the bottom surface temperature of the cooking utensil cannot be accurately measured.

  On the other hand, in the temperature detection apparatus 1 for a stove according to the first embodiment, since the fixed support member 56 is provided with the fixing concave groove 71 instead of the protrusion, the movable support tube ( The inner diameter of the lower end of the holder 53 only needs to be somewhat larger than the outer diameter of the lower end portion of the fixed side support member 56, and the gap 75 between the lower end of the movable side support cylinder 53 and the fixed side support member 56 is narrowed. be able to. As a result, the contact body 51 that is thermally coupled to the thermistor 57 as the temperature detection means is supported even when a lateral force is applied to the contact body 51 in the operating state of the temperature detection device 1 for a stove. The inclination of the moving support cylinder (holder) 53 is suppressed, and the contact body 51 can be properly brought into contact with the bottom surface of the cooking utensil such as a pan. The bottom surface temperature can be accurately measured.

  The fixing groove 71 includes (a) a method in which the fixing side support member 56 formed in a cylindrical shape is pressed in the radial direction to form the fixing groove 71, and (b) the fixing groove 71. The portion to be formed is formed in advance on a plate-like member by press working or the like, and a method of winding the same, (c) the fixed groove 71 for fixing by cutting the fixed side support member 56 formed. It is possible to form by various methods, such as a method of forming.
