[0015] However, the present disclosure is not limited to this configuration. In the present disclosure, the table may be provided so as not to be rotatable relative to the housing. The table may be provided so as to be detachable from the housing.

[0016] The table 20 has an arrangement surface 20a facing the cooking chamber 10a (upper side). A mounting base 30 is placed on the arrangement surface 20a.

[0017] The placing table 30 can be moved in and out of the cooking chamber 10a. The placing table 30 is provided separately from the table 20. The placing table 30 has a placing portion 31 and a plurality of legs 32. The placing portion 31 is a portion for placing food, for example. The placing portion 31 is located above the placement surface 20a. The placing portion 31 is spaced apart from the placement surface 20a in the height direction. The plurality of legs 32 are connected to the placing portion 31. Each of the plurality of legs 32 extends downward from the placing portion 31 (towards the placement surface 20a). The placing portion 31 is supported on the placement surface 20a by these plurality of legs 32.

[0018] A tray 40 is placed on the table 20. The tray 40 can be inserted into and removed from the cooking chamber 10a. The tray 40 is provided separately from the table 20.

[0021] (Placement table 30) The mounting table 30 will be described in detail mainly with reference to FIGS. 5 to 8, 13 and 14. FIG.

[0022] The mounting table 30 is a metal member. The mounting portion 31 of the mounting table 30 is dish-shaped with its periphery protruding upward. As shown in FIG. 5 , the mounting portion 31 is non-circular in plan view. The mounting portion 31 has a directional shape in plan view. The shape of the mounting portion 31 in plan view may be, for example, a polygonal shape, an elliptical shape, an oval shape, or the like. In this embodiment, specifically, the shape of the mounting portion 31 in plan view is polygonal. The shape of the mounting portion 31 in plan view may be, for example, a triangular shape, a quadrangular shape, a pentagonal shape, a hexagonal shape, a heptagonal shape, an octagonal shape, or the like. More specifically, in this embodiment, the shape of the mounting portion 31 in plan view is octagonal.

[0023] In this disclosure, the term "polygon" includes polygons with rounded or chamfered corners.

[0024] The mounting portion 31 has a main body 31a and a side wall 31b. The main body 31a is flat. The main body 31a has a non-circular shape in a plan view, specifically, a polygonal shape. The main body 31a has a plurality of through-holes 31a1 formed therein. Therefore, liquids such as water and oil generated from ingredients placed on the main body 31a flow through the plurality of through-holes 31a1 and fall below the mounting table 30. For example, liquids generated from ingredients during heating are sometimes called "drip."

[0025] The side wall 31b is connected to the peripheral edge of the main body 31a. The side wall 31b extends upward from the main body 31a. The side wall 31b is provided in an annular shape around the entire periphery of the main body 31a.

[0026] A plurality of legs 32 are fixed to the mounting portion 31. As shown in Fig. 6, each of the plurality of legs 32 has a fixing portion 33, a connecting portion 34, and an installation portion 35. The fixing portion 33 has The mounting portion 35 is a portion fixed to the underside of the placement portion 31. The installation portion 35 is a portion placed on the placement surface 20a of the table 20. The connection portion 34 connects the fixing portion 33 and the installation portion 35. In this embodiment, each of the multiple legs 32 is made of a single bent metal rod.

[0027] When the mounting base 30 is placed on the table 20, the fixing portion 33 extends substantially parallel to the placement surface 20a together with the mounting portion 31. The fixing portion 33 is composed of two rod-shaped portions.

[0028] The upper end of the connecting portion 34 is connected to the outer end of the fixed portion 33. The connecting portion 34 extends downward from the fixed portion 33 in the up-down direction. More specifically, the connecting portion 34 extends diagonally downward and outward from the outer end of the fixed portion 33. The connecting portion 34 is made up of two rod-shaped portions provided respectively for the two rod-shaped portions that make up the fixed portion 33.

[0029] As shown in FIG. 8, the installation portion 35 is connected to the lower end of the connection portion 34. The installation portion 35 extends from the lower end of the connection portion 34 along the extension direction of the arrangement surface 20a (a direction perpendicular to the extension direction of the central axis A). The installation portion 35 extends radially outward from the connection portion with the connection portion 34, centered on the central axis A. The installation portion 35 is composed of a single rod-shaped portion having a curved portion. In this embodiment, substantially the entire installation portion 35 is composed of a curved portion that is curved in an arc shape.

[0030] One end of the rod-shaped portion that constitutes the installation portion 35 is connected to the lower end of one of the two rod-shaped portions that constitute the connection portion 34, and the other end is connected to the lower end of the other of the two rod-shaped portions that constitute the connection portion 34. The two rod-shaped portions that constitute the connection portion 34 are connected to each other by this installation portion 35.

[0031] As shown in FIG. 13 , in this embodiment, the multiple legs 32 specifically include four legs: a first leg 32a, a second leg 32b, a third leg 32c, and a fourth leg 32d. The four legs 32a, 32b, 32c, and 32d are arranged at equal intervals in the circumferential direction. The four legs 32a, 32b, 32c, and 32d are arranged at 90° intervals around the central axis A. As described above, in this embodiment, the mounting portion 31 is octagonal. The four legs 32a, 32b, 32c, and 32d are connected to corners of the octagonal mounting portion 31. As such, the number of legs 32 is preferably a divisor of the number of corners of the mounting portion 31. For example, the number of legs 32 is preferably a divisor of the number of corners of the mounting portion 31, is less than the number of corners, and is equal to or greater than 3.

[0032] (Tray 40) Next, the tray 40 will be described in detail with reference to FIGS. 4, 6, and 8 to 10. FIG.

[0033] Tray 40 is placed on table 20 below placing portion 31. Specifically, tray 40 includes a portion of main body 31a that is located below the area where multiple through-holes 31a1 are provided. Therefore, drips generated from food placed on placing portion 31 and that fall through multiple through-holes 31a1 are caught by tray 40. For this reason, tray 40 is sometimes called a "drip tray." Note that food may also be placed on tray 40, for example. When steaming food placed on placing portion 31, water or the like may be stored in tray 40. When smoking food placed on placing portion 31, an object other than food, such as a piece of wood, may also be placed on tray 40.

[0034] The tray 40 is dish-shaped with a central portion recessed downward. As shown in Fig. 9, the tray 40 has a circular shape in plan view. However, in the present disclosure, the shape of the tray in plan view is not particularly limited. The shape of the tray in plan view may be, for example, a polygonal shape, an elliptical shape, an oval shape, or the like. It is preferable that the shape of the tray in plan view be a rotationally symmetric shape.

[0035] As shown in FIG. 10, the tray 40 has a main body 41 and a side wall 42. The main body 41 has a circular shape in a plan view. The main body 41 is plate-shaped. A plurality of protrusions 41a are provided on the surface of the main body 41. Each of the plurality of protrusions 41a is linear and has a longitudinal direction along one direction. The plurality of protrusions 41a are parallel to one another.

[0036] The side wall 42 is connected to the peripheral edge of the main body 41. The side wall 42 extends upward from the main body 41. The side wall 42 is provided in an annular shape around the entire periphery of the main body 41.

[0037] (Table 20) Next, the table 20 will be described in detail with reference to FIGS.

[0038] The table 20 is provided in the shape of a plate having a recessed portion recessed downward. As shown in FIG. 5, the shape of the table 20 in a plan view is circular. As shown in FIG. 11, the table 20 has a main body 22 and a side wall 23. The main body 22 is substantially flat. The shape of the main body 22 in a plan view is circular. The placement surface 20a is provided on this main body 22.

[0039] The side wall 23 is connected to the periphery of the main body 22. The side wall 23 extends upward in the height direction from the main body 22. More specifically, the side wall 23 extends upward from the connection portion with the main body 22 toward the outside in the radial direction.

[0040] (Placement surface 20a) As shown in FIGS. 11 and 12, two protrusions, a first protrusion 24a and a second protrusion 24b, are provided on the arrangement surface 20a. The first protrusion 24a and the second protrusion 24b are arranged at positions spaced apart from each other in the circumferential direction about the central axis A. The first protrusion 24a and the second protrusion 24b are provided at different positions from each other in the circumferential direction. The first protrusion 24a and the second protrusion 24b do not have overlapping portions in the radial direction. As shown in FIG. 6, the first protrusion 24a and the second protrusion 24b face each other in the circumferential direction in a side view.

[0041] The central axis A is equal to the axis of the table 20. The central axis A is a straight line that passes through the centroid of the table 20, which has a circular shape in a plan view, and extends along the height direction.

[0042] The first protrusion 24a has a generally trapezoidal shape in plan view. Specifically, the first protrusion 24a has a right-angled trapezoidal shape.

[0043] The first protrusion 24a has a side surface 24a1, a side surface 24a2, and a top surface 24a3.

[0044] The side surface 24a1 faces the second protrusion portion 24b in the circumferential direction. The side surface 24a1 extends from the radially outer side toward the radially inner side, tilting relative to the radial direction in a direction away from the second protrusion portion 24b in the circumferential direction. In a plan view, the side surface 24a1 has a central portion located at the radial center and extending substantially linearly, a curved portion located radially inward from the central portion and curving in a direction away from the second protrusion portion 24b in the circumferential direction toward the radially inner side, and a curved portion located radially outward from the central portion and curving in a direction toward the second protrusion portion 24b in the circumferential direction. As shown in FIG. 7, the side surface 24a1 extends in a tilted direction along the height direction. Specifically, the side surface 24a1 extends in a tilted direction toward the upward direction away from the second protrusion portion 24b in a side view.

[0045] 11, the side surface 24a2 extends substantially in the circumferential direction. The side surface 24a2 is perpendicular to the radial direction. In this embodiment, the side surface 24a2 has a substantially linear shape in a plan view.

[0046] 11, the top surface 24a3 is substantially parallel to the placement surface 20a. The top surface 24a3 is a flat surface.

[0047] 11, the second protrusion 24b has a generally trapezoidal shape in a plan view. Specifically, the second protrusion 24b has a right-angled trapezoidal shape. The second protrusion 24b and the first protrusion 24a are arranged so that their acute base angles in a plan view face each other.

[0048] The second protrusion 24b has a side surface 24b1, a side surface 24b2, and a top surface 24b3.

[0049] The side surface 24b1 faces the first protrusion 24a in the circumferential direction. The side surface 24b1 extends from the radially outer side toward the radially inner side, slanting relative to the radial direction in a direction away from the first protrusion 24a in the circumferential direction. In a plan view, the side surface 24b1 has a central portion located at the radial center and extending substantially linearly, a curved portion located radially inward from the central portion and curved in a direction away from the first protrusion 24a in the circumferential direction toward the radially inner side, and a curved portion located radially outward from the central portion and curved in a direction toward the first protrusion 24a in the circumferential direction. As shown in FIG. 7, the side surface 24b1 extends in a slanted direction along the height direction. Specifically, the side surface 24b1 extends in a direction slanting upward in a direction away from the first protrusion 24a in a side view.

[0050] 11, the side surface 24b2 extends substantially in the circumferential direction. The side surface 24b2 is perpendicular to the radial direction. In this embodiment, the side surface 24b2 has a substantially linear shape in a plan view.

[0051] The distance between the side surface 24b2 of the second protrusion 24b and the central axis A and the distance between the side surface 24a2 of the first protrusion 24a and the central axis A are substantially equal to each other.

[0052] 11, the top surface 24b3 is substantially parallel to the placement surface 20a. The top surface 24b3 is a flat surface.

[0053] The height of the second protrusion 24b and the height of the first protrusion 24a are substantially equal to each other.

[0054] As shown in FIG. 11 , in this embodiment, multiple pairs of protrusions are provided, each of which is composed of a first protrusion 24a and a second protrusion 24b. The multiple pairs of protrusions are arranged such that the first protrusion 24a included in one of adjacent pairs of protrusions in the circumferential direction and the second protrusion 24b included in the other are adjacent in the circumferential direction. A portion of the first protrusion 24a opposite the side surface 24a1 is integral with a portion of the second protrusion 24b opposite the side surface 24b1. This forms an integral protrusion 25 consisting of the first protrusion 24a and the second protrusion 24b. In this embodiment, the multiple protrusions 25 are arranged at intervals in the circumferential direction. The number of protrusions 25 is a natural number multiple of the number of installation portions 35. The number of protrusions 25 is preferably at least twice the number of installation portions 35. Specifically, in this embodiment, the number of protrusions 25 is four times the number of installation portions 35. The planar shape of each of the multiple protrusions 25 is a substantially isosceles trapezoid. In plan view, the protrusions 25 are substantially congruent with the portions formed between two protrusions 25 adjacent to each other in the circumferential direction.

[0055] (Installation of the mounting table 30) 8, the installation portion 35 of the mounting base 30 has substantially the same shape as the portion between the first protrusion 24a and the second protrusion 24b that are adjacent in the circumferential direction. Therefore, the installation portion 35 is fitted into the portion between the first protrusion 24a and the second protrusion 24b that are adjacent in the circumferential direction. In this embodiment, as described above, the number of the protrusions 25 is a natural number multiple of the number of the installation portions 35. Therefore, the mounting base 30 can be installed on the table 20 in such a manner that the installation portion 35 of each of the four legs 32a, 23b, 23c, and 23d is fitted into the portion between the first protrusion 24a and the second protrusion 24b that are adjacent in the circumferential direction.

[0056] 7, the outer shape of the installation portion 35 is substantially equal to the portion between the circumferentially adjacent first protrusion 24a and second protrusion 24b. The circumferential dimension of the installation portion 35 is substantially equal to the circumferential dimension of the portion between the circumferentially adjacent first protrusion 24a and second protrusion 24b. The installation portion 35 has a shape that follows the side surface 24a1 and the side surface 24b1.

[0057] The thickness of the installation portion 35 is greater than the height of the first protrusion 24a and the second protrusion 24b. The height of the installation portion 35 is greater than the height of the first protrusion 24a and the second protrusion 24b. The height of the installation portion 35 is preferably 1.1 times or more, and more preferably 1.5 times or more, the height of the first protrusion 24a and the second protrusion 24b. The height of the installation portion 35 is preferably 3 times or less, and more preferably 2.5 times or less, the height of the first protrusion 24a and the second protrusion 24b. In this embodiment, the height of the installation portion 35 is approximately twice the height of the first protrusion 24a and the second protrusion 24b. Because the cross-sectional area of ​​the rod-shaped portion constituting the installation portion 35 is circular, the height of the center of the rod-shaped portion constituting the installation portion 35 is substantially equal to the height of the first protrusion 24a and the second protrusion 24b. Therefore, the height of the part of the installation portion 35 where the dimension along the circumferential direction is greatest in the height direction is substantially equal to the height of the first protrusion 24a and the height of the second protrusion 24b.

[0058] As described above, in this embodiment, the placement surface 20a has two protrusions, the first protrusion 24a and the second protrusion 24b, which are arranged at positions spaced apart from each other in the circumferential direction. Therefore, the first protrusion 24a and the second protrusion 24b can prevent the legs 32 of the mounting base 30 from being displaced relative to the table 20 in the circumferential direction. This makes it possible, for example, to easily place the mounting base 30 at a predetermined position with high accuracy. Furthermore, for example, it is possible to prevent the mounting base 30 from being displaced or rotated relative to the table 20 due to rotation of the table 20, etc.

[0059] From the viewpoint of highly accurate positioning of the mounting base 30 and more effectively restricting displacement and rotation relative to the table 20, it is preferable to provide a plurality of protrusion pairs each consisting of a first protrusion 24a and a second protrusion 24b. The plurality of protrusion pairs are preferably provided so that a plurality of legs 32 are inserted between the first protrusion 24a and the second protrusion 24b constituting the protrusion pair. It is also preferable that the legs 32 have installation portions 35 shaped along the side surfaces 24a1, 24b1.

[0060] From the same viewpoint, it is preferable that the leg portion 32 is provided on both sides in the circumferential direction with side surfaces 24a1 and 24b1 facing each other.

[0061] As described above, in order to suitably position the mounting base 30 relative to the table 20 so that it is less likely to shift or rotate, it is preferable to place the mounting base 30 on the table 20 with the positional relationship between the legs 32 and the first and second protrusions 24a and 24b properly aligned. If the mounting portion 31 of the mounting base 30 is non-circular, the user can easily identify the positions of the legs 32 of the mounting base 30. In particular, if the mounting portion 31 is polygonal and the legs 32 are connected to the corners of the mounting portion 31, the user can easily identify the positions of the legs 32. This makes it easier to install the mounting base 30 in a suitable position relative to the table 20.

[0062] However, providing the protrusions 24a and 24b on the mounting surface 20a tends to reduce the flatness of the mounting surface 20a. Therefore, if a mounting table 30 or the like is not provided on the mounting surface 20a, it may be difficult to place other components on it. In this embodiment, the protrusions 24a and 24b have top surfaces 24a3 and 24b3 parallel to the mounting surface 20a. This allows other components to be placed more appropriately. Furthermore, the top surfaces 24a3 and 24b3 are flat. This allows other components to be placed more appropriately. Moreover, as shown in FIG. 11 , the protrusions 24a and 24b are provided on the radially outer portion of the mounting surface 20a, but not on the radially inner portion. Therefore, a flat area is secured on the radially inner portion of the mounting surface 20a relative to the protrusions 24a and 24b. This flat area allows other components to be placed more stably.

[0063] (Arrangement of the tray 40) As described above, the distance between the central axis A and the side surface 24a2 of each of the first protrusions 24a and the side surface 24b2 of each of the second protrusions 24b is substantially equal to one another. Therefore, the tray 40 can be placed on the placement surface 20a so as to be in contact with the side surfaces 24a2 and 24b2. By placing the tray 40 in this manner, it is possible to prevent the tray 40 from displacing relative to the table 20. The tray 40 can be held in an appropriate position relative to the table 20.

[0064] Another preferred embodiment of the present disclosure will be described below. In the following description, members having substantially the same functions as those in the first embodiment will be referred to by the same reference numerals, and description thereof will be omitted.

[0065] (Second embodiment) FIG. 16 is a schematic front view of the cooking device according to the second embodiment, with the door 11 drawn transparently.

[0066] In the first embodiment, an example has been described in which only one mounting table 30 is arranged. The second embodiment differs from the first embodiment in that a plurality of mounting tables 30, including mounting table 30a and mounting table 30b, are arranged on table 20.

[0067] The legs 32 of the mounting base 30a and the legs 32 of the mounting base 30b are arranged on the arrangement surface 20a so as to be positioned between different protrusions 24a, 24b of the table 20. Therefore, the positional relationship between the mounting base 30a and the mounting base 30b is unlikely to change, and contact with each other can be prevented.

[0068] It is also possible to place three or more mounting stages on the table.

[0069] (Variation) Fig. 17 is a schematic plan view of table 20 in a first modified example. Fig. 18 is a schematic plan view of table 20 in a second modified example. Fig. 19 is a schematic plan view of table 20 in a third modified example. Fig. 20 is a schematic plan view of table 20 in a fourth modified example.

[0070] The first protrusion 24a and the second protrusion 24b may be provided separately, as in a first modified example shown in Fig. 17 and a second modified example shown in Fig. 18. In the first and second modified examples, substantially the same effects as in the above embodiment can be obtained.

[0071] 19, the plurality of first protrusions 24a and the plurality of second protrusions 24b may all be integrally formed. Furthermore, at least one of the first protrusions 24a and the second protrusions 24b may also be provided in the center of the placement surface 20a. In the third modification, too, the placement table 30 can be easily placed in an appropriate position, and displacement and rotation of the placement table 30 can be suitably suppressed.

[0072] In the fourth modified example shown in FIG. 20, in addition to the first protrusion 24a and the second protrusion 24b that are integrally formed in the third modified example, a third protrusion 24c is further provided. In plan view, the third protrusion 24c is provided in an annular shape, more specifically, a circular annular shape, centered on the central axis A. The third protrusion 24c is higher than the first protrusion 24a and the second protrusion 24b. Providing this third protrusion 24c makes it possible to position the tray 40 with high precision and to suppress displacement of the tray 40. From this perspective, it is preferable that the bottom surface of the tray 40 and the inner shape of the third protrusion 24c are substantially identical.

[0073] The embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive. The scope of the present invention is defined by the claims, not by the above description, and is intended to include all modifications within the meaning and scope of the claims. Furthermore, configurations obtained by combining the configurations of the different embodiments described in this specification are also included in the scope of the present invention.
