Figure 6 As shown, in the present embodiment, the three baking units 16 are arranged in the center portion in the front-rear direction and in the upper portion in the up-down direction.

[0062] Reference Figure 8 , the structure of the drawer-type heating cooker 100 is described in detail. Figure 8 It is a block diagram showing the structure of the drawer type heating cooker 100 according to the present embodiment.

[0063] like Figure 8 As shown, the drawer-type cooking device 100 further includes a driving mechanism 4 , a control unit 5 , and a storage unit 6 .

[0064] The drive mechanism 4 includes a drive motor 41 for the drive mechanism and a rack and pinion mechanism. The rack and pinion mechanism includes a gear. The gear is attached to the front end of the motor shaft of the drive motor 41 for the drive mechanism. Figure 2 The rack portion on the rear side of the support member 25 described above is engaged.

[0065] The control unit 5 is a hardware circuit including a processor such as a CPU (Central Processing Unit). The control unit 5 controls the first heater 131, the first drive unit 133, the second heater 141, the second drive unit 143, the magnetron 151, the antenna motor 154, the energizing unit 162, the drive mechanism drive motor 41, the operation panel 3, and the storage unit 6 by executing a control program stored in the storage unit 6.

[0066] The storage unit 6 is composed of a RAM (Random Access Memory) and a ROM (Read Only Memory). The storage unit 6 stores a control program for controlling the operation of each unit of the drawer type heating cooker 100. The storage unit 6 stores setting information input by operating the operation panel 3.

[0067] Next, refer to Fig. 9 The cabinet 200 in which the drawer-type heating cooker 100 is built is described. Fig. 9 1 is a diagram showing the appearance of a cabinet 200 in which the drawer-type heating cooker 100 according to the present embodiment is housed.

[0068] The drawer-type heating cooker 100 is installed in the cabinet 200. Fig. 9 As shown, the box body 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, the lower wall 200B, the right wall 200C, the left wall 200D and the rear wall 200E form a storage portion 200F. The storage portion 200F is a rectangular space for the drawer-type heating cooker 100 to be embedded.

[0069] Next, refer to Figure 6 and Figure 7 , the flow of the first hot air F1 is described. When the first hot air circulation heating mode is executed, the first hot air F1 is blown out from the first blow-out hole 13C into the heating and cooking chamber 100A. In other words, the first blow-out hole 13C blows out the first hot air F1 along the loading portion 22. The first hot air F1 blown into the heating and cooking chamber 100A moves mainly forward along the right wall 1A, the left wall 1B, the top wall 1C and the cooking tray 222. Then, it reaches the reference Figure 2The first hot air F1 of the rear surface 21B of the door portion 21 described above reverses its moving direction and moves toward the rear. Then, the first hot air F1 moving toward the rear is sucked into the first suction hole portion 13D. In other words, the first suction hole portion 13D sucks the first hot air F1 along the loading portion 22. The first hot air F1 sucked into the first suction hole portion 13D is heated by the first heater 131 and is blown out again from the first blowing hole portion 13C into the heating and cooking chamber 100A. In this way, the first air supply portion 13 circulates air between the first heating chamber 13A and the heating and cooking chamber 100A to make the temperature in the heating and cooking chamber 100A uniform.

[0070] Next, refer to Figure 5 and Figure 6 , the flow of the second hot air F2 is described. When the second hot air circulation heating mode is executed, the second hot air F2 is blown out from the second blowing hole portion 14C into the heating and cooking chamber 100A. The second hot air F2 blown into the heating and cooking chamber 100A moves downward. Then, the second hot air F2 reaching the cooking tray 222 or the object to be heated reverses the moving direction and moves upward. The second hot air F2 moving upward is sucked into the second suction hole portion 14D. The second hot air F2 sucked into the second suction hole portion 14D is heated by the second heater 141 and blown out again from the second blowing hole portion 14C into the heating and cooking chamber 100A. In this way, the second air supply unit 14 circulates air between the second heating chamber 14A and the heating and cooking chamber 100A. In addition, when the second hot air circulation heating mode is the first mode, the second hot air F2 is blown directly onto the upper surface of the object to be heated. As a result, the object to be heated is cooked. In addition, when the second hot air circulation heating mode is the second mode, as a preliminary stage of heating and cooking the object, the second air supply unit 14 circulates air between the second heating chamber 14A and the heating and cooking chamber 100A to preheat the heating and cooking chamber 100A in a short time.

[0071] As reference Figures 1 to 9 As described above, in the present embodiment, when the drawer body 2 has been pushed into the heating and cooking chamber 100A, the first blowing hole 13C is located at a position higher than the height of the inner plate 23B of the support 23. Thus, by executing the first hot air circulation heating mode, the first hot air F1 blown out from the first blowing hole 13C is not easy to blow to the inner plate 23B of the support 23. Therefore, compared with the case where the first hot air F1 is directly blown from the first blowing hole 13C to the inner plate 23B of the support 23, the drawer body 2 is not easy to become high temperature. As a result, the drawer-type heating cooker 100 can suppress the decrease in the durability of the drawer body 2.

[0072] In addition, when the drawer body 2 has been pushed into the heating and cooking chamber 100A, the drawer type heating cooker 100 is located at a position higher than the height of the inner plate portion 23B of the support portion 23. Therefore, the drawer type heating cooker 100 performs the first hot air circulation heating mode, and the temperature in the heating and cooking chamber 100A rises quickly, which can improve the heating efficiency in the heating and cooking chamber 100A. As a result, the drawer type heating cooker 100 can also improve the heating efficiency of the heated object.

[0073] As reference Figures 1 to 9 As described above, in this embodiment, the inner plate portion 23B has a right side high body portion 23B1, a left side high body portion 23B3, and a low body portion 23B2. The low body portion 23B2 is located between the right side high body portion 23B1 and the left side high body portion 23B3. Thus, by executing the first hot air circulation heating mode, the first hot air F1 blown out from the first blowing hole portion 13C easily moves along the top surface portion 222A of the cooking tray 222. As a result, the drawer-type heating cooker 100 can reduce the generation of temperature unevenness in the heating cooking chamber 100A.

[0074] As reference Figures 1 to 9 As described above, in this embodiment, the heating chamber 1 includes a first air supply unit 13 and a second air supply unit 14. The heating chamber 1 includes a first blow-out hole 13C, a second blow-out hole 14C, a first suction hole 13D, and a second suction hole 14D. Thus, the drawer-type heating cooker 100 can perform heating and cooking under different heating conditions. Specifically, the drawer-type heating cooker 100 can perform a first hot air circulation heating mode or a second hot air circulation heating mode.

[0075] As reference Figures 1 to 9 As described above, in this embodiment, the inner wall 1E includes the first partition plate 13B. The top wall 1C includes the second partition plate 14B. Thus, the drawer-type heating cooker 100 can blow out and inhale the first hot air F1 from the inner wall 1E by driving the first air supply unit 13. The drawer-type heating cooker 100 can blow out and inhale the second hot air F2 from the top wall 1C.

[0076] As reference Figures 1 to 9 As described, in the present embodiment, the first suction hole portion 13D is located at the central portion of the inner wall 1E. The first blow-out hole portion 13C is located at the peripheral portion of the inner wall 1E. The second suction hole portion 14D and the second blow-out hole portion 14C are located at the central portion of the top wall 1C. Thus, the drawer-type heating cooker 100 can uniformly heat the object to be heated by driving the first air supply portion 13. In addition, the drawer-type heating cooker 100 can form a scorch mark on the surface of the top wall 1C side of the object to be heated by driving the second air supply portion 14.

[0077] As reference Figures 1 to 9 As described above, in the present embodiment, the baking unit 16 includes the heating unit 161 for cooking located in the cooking chamber 100A. Thus, the drawer-type cooking device 100 can perform cooking using radiant heat.

[0078] As reference Figures 1 to 9 As described above, in this embodiment, the heating unit 161 for heating and cooking is located on the top wall 1C side. The microwave supply unit 15 is located outside the bottom wall 1D. Thus, the drawer-type heating cooker 100 can supply the microwaves generated by the driving of the microwave supply unit 15 into the heating and cooking chamber 100A without being blocked by the heating unit 161 for heating and cooking.
