Therefore, height of a portion where a maximum dimension along the circumferential direction of the installation portion 35 in the height direction is substantially equal to height of the first protruding portion 24a and the second protruding portion 24b.

    [0076] As described above, in the present embodiment, the arrangement surface 20a has two protruding portions, the first protruding portion 24a and the second protruding portion 24b, arranged at positions separated from each other in the circumferential direction. For this reason, the leg portion 32 of the placing table 30 can be prevented from being displaced in the circumferential direction relative to the table 20 by the first protruding portion 24a and the second protruding portion 24b. For this reason, for example, the placing table 30 can be easily arranged at a predetermined position with high accuracy. Further, for example, it is possible to prevent the placing table 30 from being displaced or rotated relative to the table 20 along with rotation of the table 20 or the like.

    [0077] From the viewpoint of highly accurate arrangement of the placing table 30 and more effectively restricting displacement and rotation with respect to the table 20, it is preferable to provide a plurality of protruding portion pairs including the first protruding portions 24a and the second protruding portions 24b. A plurality of protruding portion pairs are preferably provided such that a plurality of the leg portions 32 are inserted into a portion between the first protruding portion 24a and the second protruding portion 24b constituting a protruding portion pair. Then, the leg portion 32 preferably has the installation portion 35 having a shape along the side surfaces 24al and 24b1.

    [0078] From a similar viewpoint, the side surfaces 24al and 24b1 facing each other are preferably provided on both sides in the circumferential direction of the leg portion 32.

    [0079] As described above, in order to suitably arrange the placing table 30 at a position where the placing table 30 is hardly displaced and rotated with respect to the table 20, it is preferable to place the placing table 30 on the table 20 by suitably matching a positional relationship between the leg portion 32 and the first protruding portion 24a and the second protruding portion 24b. In a case where the placing portion 31 of the placing table 30 is non-circular, the user can easily identify a position of the leg portion 32 of the placing table 30. In particular, in a case where the placing portion 31 has a polygonal shape and the leg portion 32 is connected to a corner portion of the placing portion 31, the user can easily identify a position of the leg portion 32. Therefore, the placing table 30 can be easily installed at a suitable position with respect to the table 20.

    [0080] When the protruding portions 24a and 24b are provided on the arrangement surface 20a, flatness of the arrangement surface 20a tends to be lowered. Therefore, in a case where the placing table 30 and the like are not provided on the arrangement surface 20a, there is a possibility that it is difficult to arrange other members. In the present embodiment, the protruding portions 24a and 24b are provided with the top surfaces 24a3 and 24b3 parallel to the arrangement surface 20a. For this reason, other members may be suitably arranged. Furthermore, the top surfaces 24a3 and 24b3 are flat. For this reason, other members may be more suitably arranged. Moreover, as illustrated in FIG. 11, the protruding portions 24a and 24b are provided in an outer side portion in the radial direction of the arrangement surface 20a, and are not provided in an inner side portion in the radial direction. Therefore, a flat region is secured in an inner side portion in the radial direction than the protruding portions 24a and 24b in the arrangement surface 20a. Other members can be more stably arranged in this flat region.

    Arrangement Mode of Tray 40

    [0081] As described above, distances between the central axis A and the side surface 24a2 of each of a plurality of the first protruding portions 24a and the side surface 24b2 of each of a plurality of the second protruding portions 24b are substantially equal to each other. Therefore, the tray 40 can be placed on the arrangement surface 20a so as to be in contact with the side surfaces 24a2 and 24b2. By installing the tray 40 in this manner, it is possible to suppress relative displacement of the tray 40 with respect to the table 20. The tray 40 can be held at an appropriate position with respect to the table 20.

    [0082] Hereinafter, another example of a preferred embodiment of the present disclosure will be described. In description below, a member having substantially a common function as that of the first embodiment will be referred to by a common reference numeral, and will be omitted from description.

    Second Embodiment

    [0083] FIG. 16 is a schematic front view of the heating cooker according to a second embodiment drawn with the door 11 shown transparent.

    [0084] In the first embodiment, the example in which only one placing table 30 is arranged is described. The second embodiment is different from the first embodiment in that, as the placing table 30, a plurality of placing tables including a placing table 30a and a placing table 30b are arranged on the table 20.

    [0085] The leg portion 32 of the placing table 30a and the leg portion 32 of the placing table 30b are arranged on the arrangement surface 20a so as to be located between different ones of the protruding portions 24a and 24b of the table 20. For this reason, a positional relationship between the placing table 30a and the placing table 30b is less likely to change, and contact with each other may be suppressed.

    [0086] Note that three or more placing tables may be arranged on the table.

    Variation

    [0087] FIG. 17 is a schematic plan view of the table 20 in a first variation. FIG. 18 is a schematic plan view of the table 20 in a second variation. FIG. 19 is a schematic plan view of the table 20 in a third variation. FIG. 20 is a schematic plan view of the table 20 in a fourth variation.

    [0088] As in the first variation illustrated in FIG. 17 and the second variation illustrated in FIG. 18, the first protruding portion 24a and the second protruding portion 24b may be provided separately. Also in the first variation and the second variation, substantially the same effect as that of the above embodiment can be obtained.

    [0089] As in the third variation illustrated in FIG. 19, all of a plurality of the first protruding portions 24a and a plurality of the second protruding portions 24b may be integrally provided. Further, at least one of the first protruding portion 24a and the second protruding portion 24b may also be provided at a central portion of the arrangement surface 20a. Also in the third variation, the placing table 30 can be easily arranged at an appropriate position, and displacement and rotation of the placing table 30 can be suitably suppressed.

    [0090] In the fourth variation illustrated in FIG. 20, a third protruding portion 24c is further provided in addition to the first protruding portion 24a and the second protruding portion 24b integrally provided in the third variation. The third protruding portion 24c is provided in an annular shape around the central axis A, specifically, in a ring shape in plan view. The third protruding portion 24c is higher than the first protruding portion 24a and the second protruding portion 24b. By providing the third protruding portion 24c, it is possible to perform prevention of displacement of the tray 40 and highly accurate positioning of the tray 40. From this viewpoint, a bottom surface of the tray 40 and an inner shape of the third protruding portion 24c are preferably substantially the same.
