Fig. 5 shows the appearance of the cooking device 100 as seen from above, diagonally rear right. Fig. 6 is a view showing the left side of the cooking device 100 with the housing 10 according to this embodiment removed.

[0015] As shown in FIGS. 1 and 3, cooking chamber 50 is housed in housing 10. An object to be heated is housed in cooking chamber 50. Cooking chamber 50 has, for example, a substantially rectangular parallelepiped shape. Specifically, as shown in FIGS. 4 to 6, cooking chamber 50 has a right wall 51, a left wall 52, an upper wall 53, a lower wall 54, and a rear wall 55. Rear wall 55 intersects with second direction D2. Right wall 51 and left wall 52 face a third direction D3. Upper wall 53 and lower wall 54 face a first direction D1. Right wall 51, left wall 52, upper wall 53, lower wall 54, and rear wall 55 are each made of, for example, stainless steel. Note that the material of each wall is not limited to stainless steel. Any metal having at least predetermined heat resistance and reflectivity characteristics may be used.

[0016] The front ends of the right wall 51, the left wall 52, the upper wall 53, and the lower wall 54 are connected to the rear surface of the front wall 16. The rear ends of the right wall 51, the left wall 52, and the lower wall 54 are connected to the front surface of the rear wall 55. The upper end of the rear wall 55 is connected to the lower surface of the upper wall 53, and the lower end of the rear wall 55 is connected to the upper surface of the lower wall 54.

[0017] 4, the front wall 16 has a first opening 161, a second opening 162, a third opening 163, an inlet 164, and an outlet 165. In other words, the housing 10 has the front wall 16 in which the first opening 161 and the second opening 162 are formed. The front wall 16 corresponds to, for example, a "wall portion." Furthermore, the first opening 161 corresponds to, for example, a "different opening," and the second opening 162 corresponds to, for example, an "opening."

[0018] The object to be heated passes through the first opening 161. The first opening 161 is formed in a substantially rectangular shape. The first opening 161 is located inside an area defined by the connection between the right wall 51, the left wall 52, the upper wall 53, and the lower wall 54 and the front wall 16.

[0019] The second opening 162 is located at a middle position in the left-right direction of the first opening 161 and below the first opening 161. Specifically, the second opening 162 is located between the lower outer wall 14 and the lower wall 54. The second opening 162 is formed in a substantially rectangular shape. The second opening 162 includes a notched opening in which there is no partition portion for the first opening 161.

[0020] The third openings 163 are provided as a pair, for example, on the left and right. The pair of third openings 163 are arranged at positions corresponding to the midpoint of the first opening 161 in the up-down direction. Specifically, the third openings 163 are arranged between the upper outer wall 13 and the lower outer wall 14. The pair of third openings 163 are also positioned on either side of the first opening 161 in the third direction D3. The third openings 163 include notched openings that do not have a partition portion for the first opening 161.

[0021] Air passes through the suction port 164 from the outside of the housing 10 to the inside of the housing 10. For example, a plurality of suction ports 164 are provided. A plurality of suction ports 164 are arranged below the first opening 161 and a plurality of suction ports 164 are arranged below the second opening 162.

[0022] Air passes through the air outlet 165 from the inside of the housing 10 to the outside of the housing 10. For example, a plurality of air outlets 165 are provided. The plurality of air outlets 165 are arranged at positions above the first opening 161.

[0023] 4 and 5, the rear wall 55 has a fourth opening 551. Air flowing in through the air inlet 164 passes through the fourth opening 551 to the rear side of the rear wall 55. For example, a plurality of fourth openings 551 may be provided. The fourth openings 551 are disposed at corresponding positions between the lower outer wall 14 and the lower wall 54.

[0024] 4 to 6, the cooking device 100 further includes a first space R1, a second space R2, a third space R3, a fourth space R4, and a fifth space R5. The second space R2 is disposed between the lower outer wall 14 and the lower wall 54. The fourth space R4 is disposed between the right outer wall 11 and the right wall 51. The fifth space R5 is disposed between the left outer wall 12 and the left wall 52.

[0025] As shown in FIGS. 5 and 6, the first space R1 is located between the upper outer wall 13 and the upper wall 53. A motor 31 and a waveguide 32 are disposed in the first space R1. The motor 31 rotates the antenna of a magnetron 33, which is a microwave generator. The waveguide 32 propagates the microwaves generated by the magnetron 33. The cooking device 100 operates in a microwave heating mode by operating the magnetron 33.

[0026] The third space R3 is disposed between the rear outer wall 15 and the rear wall 55. The magnetron 33, control board 34, high-voltage transformer 35, high-voltage capacitor 36, and cooling fan 37 are disposed in the third space R3. The control board 34, high-voltage transformer 35, and high-voltage capacitor 36 are fixed to the upper part of the lower outer wall 14 along the third direction D3. The cooling fan 37 is disposed above the high-voltage transformer 35 adjacent to the left outer wall 12. The cooling fan 37 draws air into the second space R2 through the air inlet 164. The air drawn into the second space R2 flows into the third space R3 through the fourth opening 551. The air flowing into the third space R3 cools electrical components such as the high-voltage transformer 35. After passing through the cooking chamber 50, a portion of the air is sent to the first space R1 and blown out of the housing 10 through the air outlet 165.

[0027] Next, the drawer body 20 will be described with reference to Figs. 1 to 6. The drawer body 20 can be drawn out relative to the cooking chamber 50. The drawer body 20 opens the first opening 161 by moving in the second direction D2, and closes the first opening 161 by moving in the opposite direction to the second direction D2. As shown in Figs. 1 to 6, the drawer body 20 has a door 21, left and right sliding portions 22, a lower sliding portion 61, and a mounting portion 23. The second direction D2 corresponds to, for example, "one side of the first direction." The opposite direction to the second direction D2 corresponds to, for example, "the other side of the first direction."

[0028] Door 21 is configured to be able to open and close first opening 161. Even when door 21 closes first opening 161, air inlet 164 and air outlet 165 remain open.

[0029] 4 to 6, the slide portion 22 has a movable rail 22a and a fixed rail 22b. The slide portion 22 is a nested slide mechanism that allows the movable rail 22a to slide relative to the fixed rail 22b.

[0030] The fixed rails 22b are provided in pairs, for example, on the left and right sides. The pair of fixed rails 22b is disposed in the fourth space R4 and the fifth space R5, respectively. The pair of fixed rails 22b is fixed to the outer surface of the right wall 51 and the outer surface of the left wall 52, respectively. Specifically, the fixed rails 22b are disposed along the second direction D2 at the middle position in the up-down direction of the right wall 51 (left wall 52).

[0031] The movable rails 22a are provided in pairs, for example, on the left and right sides. The front ends of the pair of movable rails 22a are connected to the rear surfaces of the left and right ends of the door 21, respectively. The pair of movable rails 22a extend in the second direction D2 and are inserted into the pair of third openings 163, respectively. When the drawer body 20 is fully pulled out from the cooking chamber 50, the length of the movable rails 22a extending from the third opening 163 in the second direction D2 is the longest. The first opening 161 is open. On the other hand, when the drawer body 20 is fully retracted into the cooking chamber 50, the length of the movable rails 22a extending from the third opening 163 in the second direction D2 is the shortest. The first opening 161 is closed by the door 21.

[0032] An object to be heated is placed on the placement portion 23. The placement portion 23 has a rear wall portion 23b, left and right side wall portions 23c, and a bottom wall portion 23d. The front ends of the left and right side wall portions 23c are connected to the rear surface of the door 21, and the rear ends of the left and right side wall portions 23c are connected to the front surface of the rear wall portion 23b. The lower ends of the left and right side wall portions 23c and the rear wall portion 23b are connected to the bottom wall portion 23d. Furthermore, the placement portion 23 is connected to the movable rail 22a via the door 21. Therefore, when the movable rail 22a is pulled out from the third opening 163, the placement portion 23 is pulled out from the cooking chamber 50 in the second direction D2 as the movable rail 22a moves.

[0033] The cooking device 100 further includes a movement mechanism 200. The movement mechanism 200 moves the drawer body 20 back and forth along the second direction D2.

[0034] The movement mechanism 200 will be described with reference to Figs. 7 to 9. Fig. 7 is a perspective view showing the drive motor 40, the rack portion 60, and the pinion 70. Fig. 8 is a perspective view showing the periphery of the second opening 162. Fig. 9 is a front view showing the rack tooth portion 62 and the pinion tooth portion 72. The movement mechanism 200 has the drive motor 40, the rack portion 60, and the pinion 70.

[0035] The rack portion 60 moves in the front-rear direction together with the drawer body 20. As shown in Figs. 1, 4, and 8, the lower slide portion 61 having the rack portion 60 extends in the front-rear direction and is inserted into the second opening 162. The front end of the slide portion 61 is connected to the rear surface of the lower part of the door 21 at the center in the left-right direction. In other words, the slide portion 61 having the rack portion 60 is connected to the drawer body 20. As shown in Figs. 7 to 9, the rack portion 60 has a rack teeth portion 62 and a first wall portion 63.

[0036] The rack tooth portions 62 are arranged at the left-right ends of the rack portion 60. A plurality of rack tooth portions 62 are provided at an end 61a of the slide portion 61, which will be described later, in the third direction D3. The rack tooth portions 62 extend in the third direction D3 from the end 61a of the slide portion 61 in the third direction D3. The plurality of rack tooth portions 62 are aligned along the second direction D2.

[0037] The pinion 70 meshes with the rack teeth portion 62. The pinion 70 rotates around a shaft 74 that extends in the vertical direction.

[0038] The first wall portion 63 is disposed at the end of the rack portion 60 in the third direction D3. The first wall portion 63 is disposed on one side or the other of the rack tooth portion 62 in the vertical direction. Specifically, the first wall portion 63 is disposed on the opposite side of the rack tooth portion 62 in the first direction D1. The first direction D1 corresponds to, for example, "one side or the other of the second direction."

[0039] One left-right end 63a of the first wall portion 63 is located further in the left-right direction than one left-right end 62a of the rack tooth portion 62. Specifically, the end 63a of the first wall portion 63 in the third direction D3 is located closer to the third direction D3 than the end 62a of the rack tooth portion 62 in the third direction D3. Because the end 63a of the first wall portion 63 in the third direction D3 is located closer to the third direction D3 than the end 62a of the rack tooth portion 62 in the third direction D3, the end 62a of the rack tooth portion 62 in the third direction D3 can be prevented from protruding in the third direction D3 from the end 63a of the first wall portion 63 in the third direction D3. This prevents the rack tooth portion 62 from being damaged.

[0040] The lower slide portion 61 has a rack portion 60, a movable rail, and a fixed rail. The slide portion 61, the movable rail, and the fixed rail are made of metal. The rack portion 60 has a rack tooth portion 62, a first wall portion 63, and a second wall portion 64. The rack portion 60 is made of synthetic resin and may be formed as a single unit. In this embodiment, slide portions are arranged on both the left and right sides and the bottom, and the rack portion 60 is arranged on the lower slide portion 61, but this is not limited to this. The rack portion 60 may be provided on at least one of the left and right slide portions 22. Note that, when considering well-balanced forward and backward movement, it is preferable to arrange the rack portion 60 on the lower slide portion 61.

[0041] As shown in Figures 7 to 9, the lower slide portion 61 extends along the second direction D2. The slide portion 61 is made of a plate-shaped member. The slide portion 61 moves along a slide rail 66 (see Figure 6). As shown in Figure 6, the slide rail 66 is fixed in a state in which it spans between the front wall 16 and the rear wall 55 along the second direction D2.

[0042] 7 to 9, a rack tooth portion 62, a first wall portion 63, and a second wall portion 64 are provided at the end of the slide portion 61 in the third direction D3. The slide portion 61, together with the first wall portion 63 and the second wall portion 64, forms a groove portion 65.

[0043] The second wall portion 64 is disposed opposite the first wall portion 63 with respect to the rack tooth portion 62. Specifically, the second wall portion 64 is disposed with the rack tooth portion 62 sandwiched between it and the first wall portion 63. An end portion 64a of the second wall portion 64 in the third direction D3 is positioned further in the third direction than an end portion 62a of the rack tooth portion 62 in the third direction D3. In this embodiment, the end portion 63a of the first wall portion 63 and the end portion 64a of the second wall portion 64 are positioned at the same position in the third direction D3. As described above, the rack tooth portion 62 can be accommodated in the groove portion 65 formed by the first wall portion 63 and the second wall portion 64. This not only prevents the end 62a of the rack tooth portion 62 in the third direction D3 from protruding in the third direction D3 from the end 63a of the first wall portion 63 in the third direction D3, but also prevents the end 62a of the rack tooth portion 62 in the third direction D3 from protruding in the third direction D3 from the end 64a of the second wall portion 64 in the third direction D3. Therefore, damage to the rack tooth portion 62 can be further prevented.

[0044] As shown in Figures 4 and 6, the rack section 60 is disposed below the placing section 23. Because the rack section 60 is disposed below the placing section 23, it is blocked by the placing section 23 and is therefore possible to prevent the rack tooth section 62 from approaching from the placing section 23 side. As a result, damage to the rack tooth section 62 can be prevented. Because the rack section 60 is disposed at a position below the placing section 23, it is blocked by the placing section 23 and is not visible to the user. As a result, it is possible to prevent deterioration of the appearance.

[0045] 7 to 9, the first wall portion 63 is disposed at a position below the rack tooth portion 62. The placement portion 23 can suppress an approach from above toward the rack tooth portion 62, and the first wall portion 63 can suppress an approach from below toward the rack tooth portion 62.

[0046] The rack teeth portion 62 is disposed at the horizontal end portion 61a of the slide portion 61. The upper surface of the rack portion 60 can be disposed facing the bottom wall portion 23d of the mounting portion 23, which further prevents the rack teeth portion 62 from being approached from above. In addition, since the rack portion 60 and the bottom wall portion 23d are disposed close to each other, the cooking appliance 100 can be made more compact. The rack portion 60 is driven by the drive motor 40.

[0047] As shown in Fig. 7, the drive motor 40 has a first pulley 41 and a clutch unit 42. The drive motor 40 is disposed, for example, in the second space R2 and fixed to the rear surface of the front wall 16. For example, when an open operation button (not shown) on the operation panel 30 is turned on, the drive motor 40 rotates forward to move the drawer body 20 and open the first opening 161. For example, when a close operation button (not shown) on the operation panel 30 is turned on, the drive motor 40 rotates backward to move the drawer body 20 and close the first opening 161.

[0048] The first pulley 41 is fixed to the tip of the drive shaft of the drive motor 40. Specifically, the first pulley 41 is fixed to the lower end of the drive shaft of the drive motor 40. The first pulley 41 transmits driving force to the pinion 70 via a belt 43.

[0049] The clutch unit 42 transmits or interrupts the driving force from the drive motor 40 to the first pulley 41. The clutch unit 42 is disposed between the motor body and the first pulley 41. For example, when the open operation button on the operation panel 30 is turned on, the clutch unit 42 is engaged, and the driving force is transmitted from the drive motor 40 to the first pulley 41. When the drawer body 20 is completely extended, the clutch unit 42 is disengaged, and the driving force from the drive motor 40 to the first pulley 41 is interrupted. For example, when the close operation button on the operation panel 30 is turned on, the clutch unit 42 is engaged, and the driving force is transmitted from the drive motor 40 to the first pulley 41. When the drawer body 20 is completely retracted, the clutch unit 42 is disengaged, and the driving force from the drive motor 40 to the first pulley 41 is interrupted. Here, the drive motor 40 does not need to include the clutch unit 42. If the drive motor 40 does not have the clutch unit 42, for example, when the open operation button on the operation panel 30 is turned on, the drive shaft of the drive motor 40 is operated, and the drive shaft of the drive motor 40 is stopped at the timing when the drawer body 20 is completely drawn out. The same applies when the close operation button on the operation panel 30 is turned on, for example.

[0050] The pinion 70 transmits the driving force input to the second pulley 73 via the belt 43 to the rack unit 60. Splines formed on the inner periphery of the pinion 70 are engaged with splines formed on the rotary shaft of the second pulley 73. Specifically, the pinion 70 is connected to the upper part of the rotary shaft extending upward from the second pulley 73.

[0051] The pinion 70 is made of metal. Because the rack portion 60 is made of synthetic resin, the rack portion 60 can elastically deform to follow the pinion 70. This makes it possible to suppress tooth jumping of the pinion 70 and also suppress creaking noises that occur when the pinion 70 and the rack portion 60 mesh. However, the pinion 70 may be made of synthetic resin.

[0052] As shown in FIGS. 7 and 9, the pinion 70 has a shaft portion 71 and a pinion tooth portion 72.

[0053] The pinion teeth portion 72 extends radially outward from the shaft portion 71 and meshes with the rack teeth portion 62. An upper end portion 721 of the pinion teeth portion 72 is located lower than an upper end portion 621 of the rack teeth portion 62. A lower end portion 722 of the pinion teeth portion 72 is located higher than a lower end portion 622 of the rack teeth portion 62. This makes it possible to suppress interference between the pinion teeth portion 72 and the first wall portion 63 or the second wall portion 64 when the drawer body 20 is opened, thereby suppressing noise caused by interference.

[0054] An upper end 711 of the shaft portion 71 is located above an upper end 621 of the rack tooth portion 62. A lower end 712 of the shaft portion 71 is located below a lower end 622 of the rack tooth portion 62. This allows the shaft portion 71 to be made larger, thereby increasing the rigidity of the shaft portion 71, thereby maintaining the posture of the pinion 70 and suppressing tooth jumping.

[0055] Above, embodiments of the present invention have been described with reference to the drawings (FIGS. 1 to 9). However, the present invention is not limited to the above embodiments, and can be embodied in various forms without departing from the spirit of the present invention (for example, (1) to (7) shown below).
