The pull-out body 2 further includes a pair of slide members 24 and a support member 25. The pair of slide members 24 extend in the front-rear direction and define the movement direction of the pull-out body 2. The pair of slide members 24 are fixed to the rear face 21B of the lid portion 21. Specifically, one slide member of the pair of slide members 24 includes a right side slide member 241, and the other slide member of the pair of slide members 24 includes a left side slide member 242. Each of the right side slide member 241 and the left side slide member 242 is, for example, a member having the front-rear direction as a longitudinal direction. The right side slide member 241 and the left side slide member 242 face each other in the left-right direction. One end portion of the right side slide member 241 is attached to an edge portion on the right side of the rear face 21B of the lid portion 21. One end portion of the left side slide member 242 is attached to an edge portion on the left side of the rear face 21B of the lid portion 21.

Meanwhile, the heating chamber 1 further includes a right side slide rail 11 and a left side slide rail 12. The right side slide rail 11 is fixed on the right wall 1A in the space R between the right wall 1A and the right outer wall 1G. The left side slide rail 12 is fixed on the left wall 1A in the space R between the left wall 1B and the left outer wall 1H. Each of the right side slide rail 11 and the left side slide rail 12 is a member having the front-rear direction as a longitudinal direction. The right side slide member 241 is slidably supported by the right side slide rail 11. The left side slide member 242 is slidably supported by the left side slide rail 12.

The support member 25 supports the lid portion 21. More specifically, the support member 25 extends in the direction opposite to the second direction D2 and defines the movement direction of the pull-out body 2. One end portion of the support member 25 is attached to a center portion in the left-right direction of the rear face 21B of the lid portion 21 and below the placing portion 22. The support member 25 is, for example, a plate-like member having the front-rear direction as a longitudinal direction. The support member 25 includes a rack portion. The rack portion includes a plurality of teeth. The support member 25 may be a single plate-like member or a plurality of plate-like members.

Meanwhile, the heating chamber 1 further includes a drive mechanism 4. The drive mechanism 4 drives the support member 25. Then, the drive mechanism 4 is positioned below the heating cooking chamber 100A. Specifically, the drive mechanism 4 is accommodated in the space R between the bottom wall 1D and the bottom outer wall 1F. For example, the drive mechanism 4 includes a drive motor 41, a pinion, and a drive rail 42. The drive rail 42 is fixed in the space R between the bottom wall 1D and the bottom outer wall 1F. The drive rail 42 is a member having the front-rear direction as a longitudinal direction. The support member 25 is slidably supported by the drive rail 42. The pinion is attached to an end portion of the drive motor 41. The pinion engages with the rack portion of the support member 25. Furthermore, the support member 25 moves in the front-rear direction as a result of rotation of the pinion. Note that the drive mechanism 4 may drive at least one of the support member 25, and the right side slide member 241 and the left side slide member 242. Further, in a case where the right side slide member 241 and the left side slide member 242 are driven, the drive mechanism 4 may be positioned on the side of the heating cooking chamber 100A.

Next, the heating chamber 1 will be further described with reference to FIG. 4 and FIG. 5. FIG. 4 and FIG. 5 are schematic cross-sectional views of the heating chamber 1. More specifically, FIG. 4 is a cross-sectional view of the heating chamber 1 taken along a plane orthogonal to the third direction D3. FIG. 5 is a cross-sectional view illustrating the heating chamber 1 taken along a plane orthogonal to the second direction D2.

As illustrated in FIG. 4 and FIG. 5, the pull-out type heating cooking apparatus 100 further includes a microwave supply unit 15. The microwave supply unit 15 supplies microwaves into the heating cooking chamber 100A.

The microwave supply unit 15 is fixed to the heating cooking chamber 100A. Specifically, the microwave supply unit 15 is fixed below the heating cooking chamber 100A. More specifically, the microwave supply unit 15 is positioned outside of the heating cooking chamber 100A via the bottom wall 1D.

Specifically, the microwave supply unit 15 includes a partitioning member 15B, a radiation chamber 15A, a radiation port 15C, a magnetron 151, a waveguide 152, a rotary 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. The waveguide 152 extends along the third direction D3.

The shape of the radiation port 15C is, for example, a rectangular shape. In addition, the radiation port 15C is positioned above the radiation chamber 15A and below the heating cooking chamber 100A. Specifically, the radiation port 15C is positioned at substantially a center portion of the bottom wall 1D. The rotary antenna 153 is accommodated in the radiation chamber 15A. The antenna motor 154 drives the rotary antenna 153. The rotary antenna 153 agitates microwaves and supplies the microwaves to the heating cooking chamber 100A through the radiation port 15C.

The partitioning member 15B covers the radiation port 15C. The partitioning member 15B may be required to have a shape that can cover the radiation port 15C. The partitioning member 15B is preferably a plate-like member. Further, when viewed in the up-down direction, the shape of the partitioning member 15B is, for example, a rectangular shape.

The material of the partitioning member 15B is a non-metal, and includes ceramic or glass, for example. As a result of the material of the partitioning member 15B including the ceramic or glass, the partitioning member 15B transmits microwaves. On the other hand, the material of each of the radiation chamber 15A and the waveguide 152 includes a metal.

Next, an air blowing mechanism 60 will be described with reference to FIG. 6 and FIG. 7. FIG. 6 is a perspective view illustrating the pull-out type heating cooking apparatus 100 according to the present embodiment. FIG. 7 is a right side view illustrating the pull-out type heating cooking apparatus 100 according to the present embodiment. More specifically, FIG. 6 and FIG. 7 illustrate the pull-out type heating cooking apparatus 100 from which the right outer wall 1G, the left outer wall 1H, the top outer wall 1J, the bottom outer wall 1F, and the back outer wall 1K are detached.

As illustrated in FIG. 6 and FIG. 7, the right outer wall 1G, the left outer wall 1H, the top outer wall 1J, the bottom outer wall 1F, and the back outer wall 1K can be attached to and detached from the pull-out type heating cooking apparatus 100. Specifically, an operator uses screws to attach and detach the right outer wall 1G, the left outer wall 1H, the top outer wall 1J, the bottom outer wall 1F, and the back outer wall 1K.

The pull-out type heating cooking apparatus 100 further includes the air blowing mechanism 60 and a fixing member 80. The fixing member 80 is fixed to the heating chamber 1. Specifically, the fixing member 80 is fixed below the heating cooking chamber 100A. More specifically, the fixing member 80 is fixed below the heating cooking chamber 100A by a screw. The fixing member 80 is disposed in the space R between the bottom wall 1D and the bottom outer wall 1F.

The air blowing mechanism 60 blows air onto the microwave supply unit 15. Specifically, the air blowing mechanism 60 blows air onto the magnetron 151.

More specifically, the air blowing mechanism 60 is disposed between the panel 51 and the magnetron 151. The air blowing mechanism 60 sucks the air from the outside of the heating chamber 1 through an opening portion of the panel 51, and also blows out the air toward the magnetron 151. The air blown out from the air blowing mechanism 60 moves along the magnetron 151. In other words, the air blowing mechanism 60 blows out the air in the direction opposite to the second direction D2.

Next, the air blowing mechanism 60 will be described in detail with reference to FIG. 8 to FIG. 10. FIG. 8 and FIG. 9 are perspective views illustrating the air blowing mechanism 60 and the fixing member 80 according to the present embodiment. More specifically, FIG. 8 is a perspective view illustrating the air blowing mechanism 60 attached to the fixing member 80. On the other hand, FIG. 9 is a perspective view illustrating the air blowing mechanism 60 detached from the fixing member 80. Further, FIG. 10 is a perspective view illustrating the air blowing mechanism 60 detached from the fixing member 80. As illustrated in FIG. 8 and FIG. 9, the fixing member 80 includes a first plate 81 and a second plate 82.

The first plate 81 extends along the first direction D1 and the second direction D2. Specifically, the first plate 81 is orthogonal to the third direction D3. The first plate 81 includes an attachment portion 85. Specifically, the first plate 81 includes two attachment portions 85. Each of the two attachment portions 85 is, for example, a screw hole. Each of the two attachment portions 85 passes through along the third direction D3. A screw can be attached to and detached from each of the two attachment portions 85.

The second plate 82 is orthogonal to the second direction D2. More specifically, the second plate 82 extends from the first plate 81 along the direction opposite to the third direction D3. Specifically, the second plate 82 extends along the direction opposite to the third direction D3 from the side, in the direction opposite to the second direction D2, of the first plate 81. Further, the height of the second plate 82 is lower than the height of the first plate 81.

Meanwhile, the air blowing mechanism 60 includes a fan 61 and a motor 62. In the present embodiment, the air blowing mechanism 60 further includes a first attachment member 70. In other words, the air blowing mechanism 60 is unitized.

The fan 61 includes an exhaust hole on the side in the direction opposite to the second direction D2. The fan 61 further includes an air intake hole on the side in the direction opposite to the first direction D1. The fan 61 is, for example, a sirocco fan. The motor 62 drives the fan 61. The motor 62 is disposed below the fan 61.

The first attachment member 70 is disposed on the third direction D3 side of the fan 61. Further, the first attachment member 70 is disposed below the fan 61. The first attachment member 70 includes an attachment portion 75. Specifically, the first attachment member 70 includes two attachment portions 75. Each of the two attachment portions 75 is, for example, a screw hole. Each of the two attachment portions 75 passes through along the third direction D3. A screw can be attached to and detached from each of the two attachment portions 75. The two attachment portions 75 are fixed to the two attachment portions 85 with screws, respectively.

In the present embodiment, the fixing member 80 further includes a support portion 83. The support portion 83 supports the first attachment member 70. Specifically, the support portion 83 includes a horizontal plate 83a disposed on the side, in the direction opposite to the third direction D3, of the first plate 81. The first attachment member 70 is placed on the horizontal plate 83a.

As described above with reference to FIG. 1 to FIG. 10, the air blowing mechanism 60 includes the first attachment member 70, and the fixing member 80 is fixed to the heating chamber 1. Since the support portion 83 of the fixing member 80 supports the first attachment member 70, the air blowing mechanism 60 can be restricted from moving downward with respect to the fixing member 80. In other words, in a state in which the support portion 83 supports the first attachment member 70, the operator can attach and detach the air blowing mechanism 60 to and from the fixing member 80. As a result, the operator can easily attach and detach the air blowing mechanism 60 to and from the fixing member 80. For example, the operator can easily fix the attachment portion 75 of the first attachment member 70 and the attachment portion 85 of the fixing member 80 with a screw using a screwdriver, without supporting the air blowing mechanism 60. Further, the operator can attach and detach the air blowing mechanism 60 to and from the fixing member 80 within a short period of time.

Further, even when the fixing member 80 is fixed below the heating cooking chamber 100A, the operator can easily attach and detach the air blowing mechanism 60 to and from the fixing member 80. For example, the operator can insert the screwdriver between the bottom wall 1D and the bottom outer wall 1F and fix the attachment portion 75 and the attachment portion 85 with the screw, without supporting the air blowing mechanism 60.

More specifically, the first attachment member 70 further includes an engagement portion 71. Specifically, the engagement portion 71 is a recessed portion recessed toward the first direction D1. More specifically, the engagement portion 71 is a recessed portion that becomes smaller toward the first direction D1. The shape of the recessed portion is, for example, a trapezoid.

The horizontal plate 83a engages with the engagement portion 71. Specifically, the horizontal plate 83a is disposed in the recessed portion. As a result, the air blowing mechanism 60 is disposed at a predetermined position with respect to the fixing member 80. Thus, the operator can more easily attach and detach the air blowing mechanism 60 to and from the fixing member 80.

More specifically, the fixing member 80 further includes an inclined plate 84. Specifically, the fixing member 80 further includes two inclined plates 84. Each of the two inclined plates 84 is disposed on the side, in the direction opposite to the third direction D3, of the first plate 81. Further, each of the two inclined plates 84 is disposed above the horizontal plate 83a. Further, one of the two inclined plates 84 is disposed further in the second direction D2 than the horizontal plate 83a. The other of the two inclined plates 84 is disposed further in the direction opposite to the second direction D2 than the horizontal plate 83a. Each of the two inclined plates 84 is inclined toward the horizontal plate 83a.

The first attachment member 70 is disposed between the horizontal plate 83a and the two inclined plates 84. More specifically, when the operator attaches the air blowing mechanism 60 to the fixing member 80, if the first attachment member 70 moves toward the third direction D3, the two inclined plates 84 guide the first attachment member 70 toward the horizontal plate 83a. As a result, the operator can easily dispose the air blowing mechanism 60 at the predetermined position with respect to the fixing member 80.

More specifically, the fixing member 80 further includes a placing portion 82a. The placing portion 82a is disposed at the upper end of the second plate 82. The placing portion 82a extends from the upper end of the second plate 82 toward the second direction D2. The placing portion 82a is, for example, a horizontal plate. Further, an attachment portion 82b is disposed on the side, in the direction opposite to the third direction D3, of the placing portion 82a. The attachment portion 82b is, for example, a screw hole. The attachment portion 82b passes through along the first direction D1. A screw can be attached to and detached from the attachment portion 82b. Further, the placing portion 82a includes a recessed portion 82c disposed on the side, in the direction opposite to the third direction D3, of the placing portion 82a. The recessed portion 82c is recessed toward the third direction D3.

Meanwhile, the air blowing mechanism 60 further includes a second attachment member 72. The second attachment member 72 extends from the first attachment member 70 along the direction opposite to the third direction D3. Specifically, the second attachment member 72 extends from the upper end of the first attachment member 70 along the direction opposite to the third direction D3. The second attachment member 72 is, for example, a horizontal plate. Further, an attachment portion 72a is disposed on the side, in the direction opposite to the third direction D3, of the second attachment member 72. The attachment portion 72a is, for example, a screw hole. The attachment portion 72a passes through along the first direction D1. A screw can be attached to and detached from the attachment portion 72a. Further, the second attachment member 72 includes a protruding portion 72b disposed on the side, in the direction opposite to the third direction D3, of the second attachment member 72. The protruding portion 72b protrudes downward.

The second attachment member 72 is placed on the placing portion 82a. As a result, even when the operator releases his/her hand from the air blowing mechanism 60, the air blowing mechanism 60 is maintained at the predetermined position with respect to the fixing member 80. Thus, the operator can easily attach and detach the air blowing mechanism 60 to and from the fixing member 80. Further, the protruding portion 72b is disposed in the recessed portion 82c. Furthermore, the air blowing mechanism 60 can be firmly fixed to the fixing member 80 by fixing the attachment portion 82b and the attachment portion 72a with a screw. As a result, when the air blowing mechanism 60 is driven, vibration of the air blowing mechanism 60 can be suppressed.

More specifically, the air blowing mechanism 60 further includes a third attachment member 73. The third attachment member 73 is disposed on the side, in the direction opposite to the third direction D3, of the fan 61. The third attachment member 73 is, for example, a rectangular frame body. The third attachment member 73 is orthogonal to the third direction D3. An attachment portion 73a is disposed at the upper end of the third attachment member 73. Specifically, two attachment portions 73a are disposed at the upper end of the third attachment member 73. Each of the two attachment portions 73a is, for example, a screw hole. Each of the two attachment portions 73a passes through along the first direction D1. A screw can be attached to and detached from each of the two attachment portions 73a.

The third attachment member 73 is attached to the heating chamber 1. As a result, the air blowing mechanism 60 can be firmly fixed to the fixing member 80. Thus, when the air blowing mechanism 60 is driven, the vibration of the air blowing mechanism 60 can be suppressed.
