The silicon material is excellent in heat resistance, and has high elasticity and high flexibility even at high temperatures. By using a silicon material for the elastic body 33, it is possible to prevent the top plate 21 from being scratched by pressure contact with the elastic body 33.

  FIG. 5 is a bottom perspective view showing the configuration of the top unit 20. As shown in FIG. As shown in FIG. 5, the top plate unit 20 has a rectangular flat top plate 21 on which the object to be heated is placed on the upper surface (the surface on the back side in FIG. 5) and the top plate 21 downward (in FIG. 5). And an under frame 22 supported from the front side). The top plate 21 is formed of heat-resistant tempered glass or the like.

  The under frame 22 has a frame-like shape in which an opening 22 a is formed inside, and supports the outer peripheral portion of the top plate 21. The under frame 22 is formed of, for example, a metal. The under frame 22 and the top plate 21 are fixed to each other by adhesion or the like. Moreover, the under frame 22 is removably attached to the upper surface of the cooker main body 10 using an attachment member not shown.

  The under frame 22 has a plurality of support pieces 23 for supporting the at least one coil holding member 32 (in this example, two coil holding members 32) from below. Each of the plurality of support pieces 23 is, for example, integrally formed with the under frame 22 main body, and protrudes downward from the open end of the under frame 22 toward the opening 22 a. The root portion of the support piece 23 is in contact with the lower surface of the top plate 21, and the tip end portion of the support piece 23 sandwiches the projecting portion 32 b of the coil holding member 32 and the elastic body 33 with the lower surface of the top plate 21. (See Figure 7). For this reason, the support piece 23 has a Z-shaped cross section. The number of support pieces 23 corresponds to the number of protrusions 32 b (contact surface S1). That is, in the present embodiment, since the two coil holding members 32 are each provided with two projecting portions 32 b, a total of four supporting pieces 23 are provided.

  At least a part of the upper surface portion of the support piece 23 is provided with a contact surface S2 (second contact surface) that contacts the contact surface S1 of the lower surface of the protrusion 32b.

Further, the engagement projection 34 of the coil holding member 32 is fitted in the vertical direction (the left and right direction in FIG. 7) with the engagement hole 24 of the support piece 23. Thereby, the movement of the engagement protrusion 34 in the horizontal plane is restricted. In this example, since two sets of the elastic body 33, the engagement protrusion 34, and the engagement hole 24 are provided for one heating coil unit 30, the movement is restricted at two points of the heating coil unit 30. Thus, movement and rotation of the heating coil unit 30 in the horizontal plane are restricted. Furthermore, since the contact surface S1 of the coil holding member 32 and the contact surface S2 of the support piece 23 are in pressure contact with each other, the inclination of the heating coil unit 30 with respect to the horizontal surface is also restricted. By restricting the movement, rotation, and inclination of the heating coil unit 30, the positional deviation of the heating coil 31 with respect to the top plate unit 20 can be prevented.

  In the state shown in FIG. 7, the elastic body 33 is in the state of being compressed in the vertical direction with the compression displacement P1 (P1> 0). Further, the upper end surface 32c1 of the wall portion 32c is located in the same plane as or above the upper surface 31a of the heating coil 31. A portion 33a of the elastic body 33 is provided on the upper end surface 32c1 of the wall portion 32c. That is, a portion 33 a of the elastic body 33 is disposed between the upper end surface 32 c 1 of the wall 32 c and the lower surface of the top plate 21. A gap C1 (first gap) in the vertical direction is formed between the upper surface 31a of the heating coil 31 and the lower surface of the top plate 21. In the gap C1, a cooling air blown by a blower unit (not shown) flows.

  Next, an example of a procedure for removing the heating coil unit 30 (coil holding member 32) from the top plate unit 20 will be described. Here, before the heating coil unit 30 is removed from the top plate unit 20, the top plate unit 20 is removed from the cooker body 10. At this time, the top unit 20 may be placed on the work bench with the front and back turned up as shown in FIG. That is, the expressions such as "upper" or "lower" in the following description are based on the induction heating cooker 1 installed in a usable state, and the actual vertical direction at that time is not necessarily the same. It does not match.

  FIG. 8 is a cross-sectional view showing a state in which the coil holding member 32 is pressed upward by an external force. FIG. 9 is a cross-sectional view showing a main part of FIG. 8 in an enlarged manner. As shown in FIGS. 8 and 9, when the coil holding member 32 is pressed upward (“pressing direction” shown in FIGS. 6 and 8) against the biasing force of the elastic body 33, the elastic body 33 is vertically moved. The compression displacement of the elastic body 33 increases from P1 to P2 (P2> P1). At this time, the engagement projection 34 moves upward relative to the engagement hole 24, and is vertically moved between the tip end surface 34 a of the engagement projection 34 and the engagement hole 24 (upper surface portion of the support piece 23). A directional gap C2 (second gap) is formed. Thereby, the engagement between the engagement protrusion 34 and the engagement hole 24 is released. By disengaging the heating coil unit 30 at two points, movement and rotation in the horizontal plane of the coil holding member 32 are allowed. In this state, the coil holding member 32 can be removed from the under frame 22 by sliding the elastic body 33 with respect to the top plate 21 and moving the coil holding member 32 in the horizontal plane.

  Here, in the state where the coil holding member 32 is pressed upward, a portion 33 a of the elastic body 33 exists between the upper end surface 32 c 1 of the wall portion 32 c and the lower surface of the top plate 21. A gap C3 (third gap) in the vertical direction is formed between the upper surface 31a and the lower surface of the top plate 21 (C1> C3> 0). That is, even if the coil holding member 32 is pressed upward, the heating coil 31 and the top plate 21 do not contact. Therefore, it is possible to prevent the top plate 21 from being damaged by the contact with the heating coil 31.

  Next, an example of a procedure for attaching the heating coil units 30-1 and 30-2 to the top unit 20 will be described. 10 to 12 are bottom views showing the procedure for attaching the heating coil units 30-1 and 30-2 to the top plate unit 20. FIG.
