The locking portion is constituted by a convex portion formed by bending an intermediate portion of a plate spring,
It is preferable that the locked portion has a recess in which the protrusion is engaged and disengaged.

  With this configuration, that is, a simple configuration in which only the projection is engaged with the recess, damage due to long-term use can be made less likely.

  It is preferable that the leaf spring locks one end to the support member and fixes the other end.

  According to this configuration, it is possible to easily assemble only by locking one end of the bent flat spring to the support member and fixing the other end.

It has a temporary fixing structure capable of temporarily fixing the support member to the reinforcing member,
The temporary fixing structure includes an insertion hole and a locking hole formed in the reinforcing member, and a insertion piece and a locking piece which are formed in the support member and inserted and locked in the insertion hole and the locking hole, respectively. Consists of
Preferably, the support member can be temporarily fixed to the reinforcing member by locking the locking piece in the locking hole in a state where the insertion piece is inserted into the insertion hole.

  With this configuration, since the support member can be temporarily fixed to the reinforcing member, the assembling workability can be improved.

  The support member preferably has a fixing portion that can be fixed to the reinforcing member after the temporary fixing.

  With this configuration, it is possible to easily obtain a fixed state at the fixing portion in a state where the support member is temporarily fixed to the reinforcing member, so that it is possible to improve the assembling workability.

  According to the present invention, since the support member for supporting the handle is made of metal and this support member can be supported by the metal reinforcing member, no large load acts directly on the main body through the handle. , Can prevent the body from being damaged.

The body portion 4 is reinforced by screwing together with a protective frame (not shown) and the like to the projection 5 a (one place is not shown).

  A supporting member 15 which is also made of a metal material (for example, stainless steel or the like) is attached to the body reinforcing plate 7. The support member 15 includes a flat portion 16, insertion pieces 17 extending from both sides of the lower end portion thereof, and locking pieces 18 extending laterally from an intermediate portion. In FIG. 3, the support member 15 is illustrated without a thickness, but in actuality, the support member 15 has high rigidity with a predetermined thickness (for example, 1 mm).

  The flat portion 16 is bent stepwise at a central portion in the vertical direction, and an upper half 19 and a lower half 20 are formed. The upper half 19 further protrudes at the upper center, and a bearing hole 21 is formed therein. A rectangular opening 22 is formed on the lower side of the bearing hole 21. A locking hole 23 is formed on one side of the opening 22 and a mounting piece 24 is provided on the other side. The mounting piece 24 is bent and protrudes to one side of the flat portion 16, and a screw hole 25 is formed at the tip end portion thereof. The leaf spring 26 is attached using the opening 22, the locking hole 23 and the attachment piece 24. One end portion of the plate spring 26 is bent in a step-like manner in accordance with the plate thickness of the flat plate portion, and is locked to the locking hole 23. Further, the middle portion of the plate spring 26 is formed of a convex portion 27 bent so as to be U-shaped. The protrusion 27 is disposed to protrude from the opening 22. Here, the convex portion 27 constitutes a locking portion of the positioning mechanism according to the present invention. Further, the other end of the plate spring 26 is bent stepwise in accordance with the shape of the mounting piece 24 and a through hole 28 is formed at the tip end thereof. The plate spring 26 is screwed to the screw hole 25 of the mounting piece 24 through the through hole 28. Here, the other end portion of the plate spring 26 in which the through hole 28 is formed constitutes the fixing portion of the present invention.

  The insertion piece 17 is formed of a first portion 17a bent in a stepwise manner and extending horizontally from both ends of the lower end portion of the flat portion 16 and a second portion 17b directed downward from there in the vertical direction. . Thereby, the second portion 17 b of the insertion piece 17 can be smoothly inserted into the insertion hole 14 of the trunk reinforcing plate 7. Then, in the inserted state, the upper surface (or the lower surface) of the first portion 17 a can contact the upper edge (or the lower edge) of the insertion hole 14.

  The locking piece 18 is formed by cutting out a part of the lower half 20 and the upper half 19 of the flat portion 16 in a U-shape and cutting and raising the obtained tongue. A screw hole 25 is formed at the tip of each locking piece 18. Then, when each locking piece 18 is inserted into the locking hole 13a of the trunk reinforcing plate 7, the upper surface (or lower surface) of the first portion of the insertion hole 14 is elastically deformed to the upper edge (or lower) of the insertion hole 14 And the support member 15 is temporarily fixed to the body reinforcing plate 7.

  A handle 29 is attached to the main body 2 rotatably. The handle 29 is a U-shaped resin material, and has a longitudinally long cross-sectional shape whose both ends are arc-shaped. At both ends of the handle 29, bearing holes 30 penetrating in the opposite direction are respectively formed. A communication hole 31 (see FIG. 4) is in communication with each bearing hole 30 from a side arc surface. The shaft member 32 rotatably supported by the bearing hole 21 of the support member 15 is inserted through the bearing hole 30. The shaft member 32 is made of a metal material such as stainless steel, and a flange 33 is formed at one end, and a circumferential groove 34 is formed on the outer peripheral surface at the other end. The C-shaped snap ring 35 inserted from the communication hole 31 engages with the circumferential groove 34 of the shaft member 32 in a state of being inserted into the bearing hole 30 of the handle 29. And the communicating hole 31 is covered by the cap member 36 (refer FIG. 4). Further, at both end portions of the handle 29, protruding portions 37 are formed on the tip side outer surface of the bearing hole 30. The protruding portion 37 is formed in an arc shape along the bearing hole 30, and a recess 38 is formed in the central portion thereof. Here, the recess 27 constitutes the locked portion of the positioning mechanism of the present invention. The convex portion 27 of the support member 15 is engaged with or disengaged from the concave portion 38.

Next, a procedure for attaching the handle 29 to the main body 2 will be described.
First, the support member 15 is temporarily fixed to the body reinforcing plate 7 screwed to the main body 2. The support member 15 inserts the insertion piece 17 into the insertion hole 14 with respect to the trunk reinforcing plate 7, and elastically locks the locking piece 18 in the locking hole 13b. Thereby, the upper surface or the lower surface of the second portion 17 b of the insertion piece 17 is in pressure contact with the upper edge or the lower edge of the locking piece 18. As a result, the temporarily fixed state of the support member 15 with respect to the trunk reinforcing plate 7 can be stabilized.

  In the temporarily fixed state, the center of the screw hole 18 a formed in the locking piece 18 of the support member 15 is disposed at a position vertically overlapping the center of the through hole 12 formed in the trunk reinforcing plate 7. Therefore, a screw is inserted into the through hole 12 and screwed into the screw hole 18 a to fix the support member 15 to the trunk reinforcing plate 7. The screwing operation can be performed in a state where the temporary fixing of the support member 15 to the trunk reinforcing plate 7 is stable. Therefore, the screwing operation can be easily performed.

  As described above, since the mounting operation of the support member 15 to the trunk reinforcing plate 7 can be performed by a simple temporary fixing operation and a screwing operation, the workability is excellent. Further, in this mounted state, the center of the bearing hole 21 of the support member 15 and the center of the notch 6 of the main body 2 are horizontally overlapped. Furthermore, the support member 15 can be disposed upward along the vertical portion 9 of the trunk reinforcing plate 7 and can be along the inner surface of the trunk 4 of the main body 2. Therefore, the space occupied by the support member 15 can be minimized.

  Subsequently, the handle 29 is attached to the support member 15 attached to the main body 2 or the trunk reinforcing plate 7. In this mounting operation, the shaft member 32 is inserted into the bearing hole 21 of the support member 15 and the bearing hole 30 of the handle 29 in a state in which both ends are positioned with respect to the notch 6 of the main body 2. When the shaft member 32 is inserted into the bearing hole 30 of the handle 29, the circumferential groove 34 of the shaft member 32 is at a position corresponding to the insertion hole 14 of the handle 29. Therefore, the snap ring 35 is inserted through the insertion hole 14 and engaged with the circumferential groove 34. Thereby, the shaft member 32 and the handle 29 are integrated. Thereafter, the cap member 36 is attached to the handle 29 and the insertion hole 14 is closed, whereby the attachment work of the handle 29 is completed.

  The rotation center O is located above the center of gravity C of the entire rice cooker 1. For this reason, it is excellent in the stability at the time of grasping and conveying rice cooker 1 in the state where handle 29 was rotated to the perpendicular position mentioned below.

  When the handle 29 is rotated forward as shown in FIG. 7A, the leaf spring 26 pushes the projection 27 by the projection 37 of the handle 29, as shown in FIG. 7B. Is elastically deformed. Then, as shown in FIG. 6A, when the handle 29 is turned in the vertical direction, as shown in FIG. 6B, the projection 27 of the plate spring 26 is in the projection 37 of the handle 29. It engages with the formed recess 38. As a result, the handle 29 is positioned at the vertical position shown in FIG. 6A, the main body 2 of the rice cooker 1 is less likely to shake, and it becomes convenient to carry.

  According to the rice cooker 1 according to the embodiment, the mounting operation of the support member 15 to the trunk reinforcing plate 7 is performed only by inserting the insertion piece 17 into the insertion hole 14 and engaging the locking piece 18 into the locking hole 23 And the screwing operation of screwing the screw into the screw hole 25 through the notch 6 from the upper side in the vertical direction. Then, the handle 29 can be attached only by engaging the snap ring 35 with the shaft member 32 inserted into the bearing hole 30 of the handle 29 through the bearing hole 21 of the support member 15. Therefore, the attachment work of the handle 29 can be easily performed.

  Further, the handle 29 is rotatably supported by a highly rigid support member 15 which is also made of a metal material and is attached to the highly rigid body reinforcing plate 7 made of a metal material. Therefore, even if a large load is applied through the handle 29, it is the support member 15 and the body reinforcing plate 7 made of a metal material, and the force exerted by the body reinforcing plate 7 on the main body 2 made of a resin material. Because the load is dispersed, local overloading does not occur and cause damage.

  In addition, this invention is not limited to the structure described in the said embodiment, A various change is possible.

  Although the support structure of the handle 29 employed in the rice cooker 1 has been described as an example of the heating cooker in the above embodiment, the support structure of the handle 29 is not limited to the rice cooker 1 but may be an electronic jar, an electric pot, The present invention can be adopted to various products provided with the handle 29 such as a pan and the like, and is particularly effective to a heavy product.

  In the embodiment described above, the locking portion is constituted by the convex portion 27 of the plate spring 26 attached to the support member 15, and the locked portion is constituted by the concave portion 38 formed on the handle 29. Is not limited. For example, the handle 29 may be provided with a ball plunger, and the recess 38 for engaging and disengaging the ball may be provided on the main body side (for example, the support member 15).

  In the said embodiment, although the penetration piece 17 was formed in two places, one place or three or more places may be sufficient. Moreover, although the locking piece 18 was formed in two places, one place or three or more places may be sufficient.

  Although the fixing portion is screwed in the above embodiment, other means such as welding and adhesion may be adopted.

  In the embodiment, the recess 38 is formed in the protrusion 37 of the handle 29. However, without providing the protrusion 37, the recess 38 may be configured to be simply recessed from the surface of the handle 29.
