[0033] The control unit 5 is a hardware circuit that includes a processor such as a CPU (Central Processing Unit). The control unit 5 executes the control program stored in the storage unit 6.

[0034] Next, refer to Figures 1-4 The pull-out body 2 and the mounting part 22 involved in this embodiment will be described. Figure 4 This is a perspective view of the pull-out body 2 and the mounting portion 22 according to this embodiment. Figures 1-4 As shown, the pull-out heating cooker 100 also includes a mounting section 22. Additionally, as... Figures 1-4 As shown, the pull-out body 2 can be freely pulled out relative to the heating cooking chamber 100A along a predetermined direction D1. The predetermined direction D1 is along the front-to-back direction. In detail, the pull-out body 2 can be pulled out relative to the heating chamber 1 and can also be introduced. Specifically, the pull-out body 2 has a pull-out body 20. The pull-out body 20 has a door portion 21 and a support portion 23.

[0035] The mounting portion 22 is capable of holding the object to be heated H. The mounting portion 22 is, for example, a plate-shaped component made of ceramic, glass, or synthetic resin, preferably a plate-shaped component made of ceramic or glass. As a result, the mounting portion 22 is microwave-transparent. Furthermore, the mounting portion 22 is transparent or translucent. Translucent includes colored transparency.

[0036] The door portion 21 is capable of opening and closing the opening on the front side of the heating cooking chamber 100A. The door portion 21 is a generally rectangular plate-shaped component. The door portion 21 has a front surface 21A and a rear surface 21B. When the pull-out body 2 is pulled out of the heating cooking chamber 100A, the door portion 21 opens the opening on the front side of the heating cooking chamber 100A. When the pull-out body 2 is introduced into the heating cooking chamber 100A, the door portion 21 closes the opening on the front side of the heating cooking chamber 100A. In addition, when the pull-out body 2 is introduced into the heating cooking chamber 100A, the distance between the top wall 1C and the bottom wall 1D is shorter than the distance between the rear wall 1E and the rear surface 21B.

[0037] The support portion 23 is fixed to the rear surface 21B of the door portion 21 and supports the periphery of the mounting portion 22 in a horizontal manner. Specifically, the support portion 23 has a bottom plate portion 23A, an inner side plate portion 23B, a right side plate portion 23C, a left side plate portion 23D, and a pair of rollers 23E.

[0038] The base plate portion 23A has a rectangular opening 23A1. The rectangular opening 23A1 is located approximately in the center of the base plate portion 23A.

[0039] The inner panel 23B, right panel 23C, and left panel 23D rise upright from the periphery of the base plate 23A and are mounted on the upper side. The mounting portion 22 is fitted between the door portion 21, the inner panel 23B, the right panel 23C, and the left panel 23D. Furthermore, the periphery of the mounting portion 22 is fixed to the upper surface of the periphery of the base plate 23A.

[0040] A pair of rollers 23E rotate as the pull-out body 2 moves. Specifically, the pair of rollers 23E includes a right roller 23E1 and a left roller 23E2. The right roller 23E1 is mounted at the rear end of the right side plate portion 23C. The left roller 23E2 is mounted at the rear end of the left side plate portion 23D.

[0041] Furthermore, by pulling out the pull-out body 2, the mounting portion 22 and the support portion 23 are pulled outward from the heating cooking chamber 100A. With the pull-out body 2 inserted, the mounting portion 22 and the support portion 23 are housed within the heating cooking chamber 100A. As described above, since the mounting portion 22 is transparent or semi-transparent, users can visually confirm the components located below it. As a result, users can easily clean the bottom wall 1D of the heating cooking chamber 100A when it becomes dirty. Additionally, heated material H that falls onto the bottom wall 1D can be removed before carbonization.

[0042] In addition to the pull-out body 20, the pull-out body 2 also has a pair of sliding parts 24 and support parts 25.

[0043] Furthermore, a pair of sliding members 24 restrict the movement direction of the pull-out body 2 in the front-back direction. The pair of sliding members 24 are fixed to the rear surface 21B of the door portion 21.

[0044] Specifically, the pair of sliding members 24 includes a right sliding member 241 and a left sliding member 242. The right sliding member 241 and the left sliding member 242 are respectively members whose length direction is, for example, the front-to-back direction. The right sliding member 241 and the left sliding member 242 are opposite each other in the left-to-right direction. One end of the right sliding member 241 is mounted to the right edge of the rear surface 21B of the door portion 21. One end of the left sliding member 242 is mounted to the left edge of the rear surface 21B of the door portion 21.

[0045] On the other hand, the heating chamber 1 also has a right sliding track 11 and a left sliding track 12. The right sliding track 11 is fixed in the space between the right wall 1A and the right outer wall 1G. The left sliding track 12 is fixed in the space between the left wall 1B and the left outer wall 1H. The right sliding track 11 and the left sliding track 12 are components with the back-to-foreground direction as their length direction. The right sliding component 241 is slidably supported on the right sliding track 11. The left sliding component 242 is slidably supported on the left sliding track 12.

[0046] Support member 25 supports pull-out body 20. Specifically, support member 25 restricts the direction of movement of pull-out body 2, directing it along a predetermined direction D1. One end of support member 25 is mounted at the center of the rear surface 21B of door portion 21 in the left-right direction, positioned lower than the mounting portion 22. Support member 25 is, for example, a plate-shaped member with the front-back direction as its length. Support member 25 has a rack portion. The rack portion has multiple teeth. Support member 25 can be a single plate-shaped member or multiple plate-shaped members.

[0047] On the other hand, the heating chamber 1 also has a drive mechanism 4. The drive mechanism 4 drives the support member 25. Furthermore, the drive mechanism 4 is located below the heating cooking chamber 100A. Specifically, the drive mechanism 4 is housed in the space between the bottom wall 1D and the bottom outer wall 1F. The drive mechanism 4 includes, for example, a drive motor 41, a pinion gear, and a drive rail 42. The drive rail 42 is fixed within the space between the bottom wall 1D and the bottom outer wall 1F. The drive rail 42 is a member with the longitudinal direction as its length. The support member 25 is slidably supported on the drive rail 42. The pinion gear is mounted on the front end of the drive motor 41. The pinion gear meshes with the rack portion of the support member 25. Furthermore, by rotating the pinion gear, the support member 25 moves in the longitudinal direction. As a result, the pull-out body 2 is either in an open or closed state. Additionally, the drive mechanism 4 can also drive at least one of the support member 25, the right sliding member 241, and the left sliding member 242. Furthermore, when driving the right sliding member 241 and the left sliding member 242, the drive mechanism 4 can also be located on the side of the heating cooking chamber 100A.

[0048] As described above, since the mounting portion 22 is transparent or semi-transparent, users can visually confirm the support member 25 located below the mounting portion 22. As a result, manufacturers can easily insert the support member 25 into the drive rail 42 located at the lower center of the front surface side of the heating chamber 1 in order to align the support member 25 with the pinion.

[0049] Next, refer to Figures 1-6 The heating chamber 1 involved in this embodiment will be further described. Figure 5 and Figure 6This is a diagram showing a schematic cross-section of the heating chamber 1 according to this embodiment. More specifically, Figure 5 This represents the cross-section of the heating chamber 1 after it has been cut by a plane orthogonal to the front and rear directions. Figure 6 This represents the cross-section of heating chamber 1 after it has been cut by a plane orthogonal to the left and right directions.

[0050] like Figure 5 and Figure 6 As shown, the pull-out heating cooker 100 also includes a microwave supply unit 15 and a partition member 15B. The microwave supply unit 15 supplies microwaves to the heating cooking chamber 100A.

[0051] The microwave supply unit 15 is located outside the heating and cooking chamber 100A, separated by the bottom wall 1D. The microwave supply unit 15 includes a radiation chamber 15A, a magnetron 151, a waveguide 152, a rotating antenna 153, and an antenna motor 154. The magnetron 151 generates microwaves. The waveguide 152 propagates the microwaves generated by the magnetron 151 to the radiation chamber 15A.

[0052] The radiation chamber 55A has a radiation port 15C. The radiation port 15C is, for example, square in shape. Furthermore, the radiation port 15C is located below the heating cooking chamber 100A. Specifically, the radiation port 15C is located approximately at the center of the bottom wall 1D. A rotating antenna 153 is housed within the radiation chamber 15A. An antenna motor 154 drives the rotating antenna 153. The rotating antenna 153 stirs the microwaves, supplying microwaves into the heating cooking chamber 100A through the radiation port 15C.

[0053] As described above, a microwave supply unit 15 is provided below the heating cooking chamber 100A, so that microwaves generated by the microwave supply unit 15 can be irradiated onto the object to be heated H at a short distance. As a result, the object to be heated H can be heated efficiently.

[0054] Furthermore, the partition member 15B covers the radiation port 15C. The partition member 15B can be any shape that can cover the radiation port 15C. The partition member 15B is preferably a plate-shaped member. In addition, when viewed from the vertical direction, the shape of the partition member 15B is, for example, a square.

[0055] The material of the separator 15B includes ceramic or glass. As a result, by including ceramic or glass in the material of the separator 15B, microwaves can pass through the separator 15B. On the other hand, the materials of the radiation chamber 55A and the waveguide 152 include metal.

[0056] Furthermore, the pull-out heating cooker 100 also includes a grill section 16. Specifically, the grill section 16 has a heater 161 and an energizing unit 162. The heater 161 is located inside the heating cooking chamber 100A and heats the object H. Specifically, the heater 161 is located in the upper part of the heating cooking chamber 100A. The heater 161 is approximately U-shaped when viewed from a vertical direction. In this embodiment, three grill sections 16 are provided. The heater 161 is, for example, an encapsulated heater. The energizing unit 162 is located on the outer side of the left wall 1B. The energizing unit 162 supplies power to the heater 161. The energized heater 161 generates heat.

[0057] According to the pull-out heating cooker 100 of the present invention, a heater 161 is provided in the upper part of the heating cooking chamber 100A, and a microwave supply unit 15 is provided in the lower part of the heating cooking chamber 100A. Therefore, the heater 161 does not obstruct the irradiation of microwaves onto the object to be heated H, and conducts the heat generated by the heater 161 to the upper surface of the object to be heated H, thereby enabling efficient heating of the upper surface of the object to be heated H.

[0058] Reference Figure 7 The structure of the pull-out heating cooker 100 is described in detail. Figure 7 This is a block diagram illustrating the structure of the pull-out heating cooker 100 according to this embodiment.

[0059] In this embodiment, the pull-out heating cooker 100 has a "microwave heating mode" and a "grill heating mode" as its heating and cooking modes. The "microwave heating mode" is a mode in which the heated object H is heated and cooked by radiating microwaves into the heating and cooking chamber 100A. The "grill heating mode" is a mode in which the heated object H is heated and cooked by transferring the heat generated by the heater 161 to the heated object H.

[0060] The control unit 5 controls the drive unit 133, magnetron 151, antenna motor 154, power supply unit 162, drive motor 41, operation panel 3 and storage unit 6 by executing the control program stored in the storage unit 6.

[0061] In detail, the control unit 5 controls the driving of the microwave supply unit 15 and the grill unit 16. For example, when the "microwave oven heating mode" is selected, the control unit 5 drives the magnetron 151 and the antenna motor 154. In addition, when the "grill heating mode" is selected, the control unit 5 supplies power to the power supply unit 162.

[0062] Next, refer to Figure 8 This describes the cabinet 200 equipped with a pull-out heating cooker 100. Figure 8 This is a diagram showing the appearance of the cabinet 200 on which the pull-out heating cooker 100 according to this embodiment is installed.

[0063] The pull-out heating cooker 100 is installed inside the cabinet 200. For example... Figure 8 As shown, the cabinet 200 has an upper wall 200A, a lower wall 200B, a right wall 200C, a left wall 200D, and a rear wall 200E. The upper wall 200A, lower wall 200B, right wall 200C, left wall 200D, and rear wall 200E form a receiving section 200F. The receiving section 200F is a cuboid space in which a pull-out heating cooker 100 is installed.

[0064] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and can be implemented in various ways without departing from its spirit.

In addition, the material, shape, size, etc. of each constituent element shown in the above embodiments are examples and are not particularly limited, and various modifications can be made without substantially departing from the effects of the present invention.

[0065] (1) As referred to Figures 1 to 8 As described, the mounting portion 22 is transparent or semi-transparent, but the present invention is not limited thereto. Position information may also be arranged on the lower surface of the transparent or semi-transparent mounting portion 22. Figure 9 This is a bottom view of the mounting portion 22 according to this embodiment. Position information is provided on the lower surface of the mounting portion 22. The position information indicates the position where the heated object H is placed. The position information is, for example, a mark 22a. The shape of the mark 22a is, for example, a ring. The mark 22a is, for example, printed on the lower surface of the mounting portion 22. As described above, a microwave supply portion 15 is provided below the heating cooking chamber 100A, which can irradiate microwaves at a short distance. Furthermore, by applying the mark 22a at the point where the microwaves are most effectively irradiated, the heated object H is induced to be placed, thereby enabling more efficient heating. In addition, since the mounting portion 22 is transparent or semi-transparent, the mark 22a is difficult to contaminate and its disappearance can be suppressed by providing the mark 22a on the lower surface of the mounting portion 22.

[0066] (2) As referred to Figures 1 to 9 As explained, the pull-out heating cooker 100 may also have a hot air supply section within the heating cooking chamber 100A.
