  About the cooking-by-heating machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, the operation unit 5 is set in the operation unit port 17 by being guided from the operation unit 5 of the main body 1 to the storage unit 16 of the kitchen 15. Since the top plate 2 is formed to have a width of 60 cm which is larger than the width 56 cm of the storage unit 16, the top plate 2 is placed on the top surface of the kitchen 15 without passing through the storage unit 16, and the setting of the main body 1 is completed. A slight gap is formed between the main body 1 and the operation portion port 17.

  The pan 18 and the like are placed on the top plate 2, the operation unit 5 is operated to drive the control circuit 9, and the heating coil 3 is energized to heat the pan 18 by electromagnetic induction. When the desired heating is completed, the operation unit 5 is operated and heating of the pan 18 by the heating coil 3 is stopped.

  Since the control circuit 9 and the heating coil 3 generate heat while the heating coil 3 is being driven, the cooling fan 7 is driven to blow air. When the cooling fan 7 is driven, the sucked air is sent to the control circuit 9 and the heating coil 3 by the cooling fan 7 to be cooled.

  The air blown to the control circuit 9 cools the heat-generating components of the control circuit 9 and is exhausted upward from the exhaust port 14 located on the upper surface of the rear portion of the main body 1. At this time, steam or oily smoke discharged from the pan 18 is entrained to form an ascending current.

  A part of the air blown to the control circuit 9 is guided from the first branch part 12 and the second branch part 13 to the upper part of the substrate cover 10 and the upper part of the grill 6 on the upper part of the control circuit 9, and the upper part of the substrate cover 10 and the grille. 6 The heating coil 3 located in the upper part is cooled. After the heating coil 3 is cooled, the air is further pushed to the rear of the main body 1 and exhausted upward from the exhaust port 14 disposed in the left rear part behind the top plate 2.

  When cooking, there is a case where the top panel operation button 37 of the top panel 2 is operated and a case where the operation unit 5 is opened and operated. First, a case where the operation unit 5 is opened and operated will be described. When the glass plate 19 of the operation unit 5 is pressed, the claw 25 provided on the operation unit 5 is released from the latch 26, and the operation unit 5 is pressed by a leaf spring (not shown) to rotate around the shaft 23 for operation. It rotates until the button 21 and the display part 22 are visible. When the locking portion 28 contacts the stopper 27, the rotation stops.

  When the operation unit 5 is opened, the speaker 29 faces the operator. When the operation button 21 is pressed during cooking or during cooking, the operation content and the operation content of the main body during cooking are displayed on the display unit 22, and the control circuit 9 guides the speaker 29 by voice to confirm the operation. The sound emitted from the speaker 29 is heard by the operator through the front tube portion 30 via the operation portion 5, while passing through the rear tube portion 31 from the opposite side of the speaker 29 and through the operation portion hole 34. The sound passes through 35 and is diffused to the outside of the main body 1, so that the sound reaches the outside through a gap 39 between the operation unit port 17 and the lower surface of the main body 1, resulting in a large and clear sound that is easy for the operator to hear. Since the speaker 29 and the rear cylinder part 31 are in a straight line, and the operation part hole 34 and the through hole 35 are located near the straight line of the speaker 29, the sound is easily diffused to the outside of the main body 1, which is large for the operator. A clear sound will arrive. The operator will receive the sum of the sound emitted from the front of the speaker 29 and the sound emitted from the back of the speaker 29.

Next, a case where the operation unit 5 is closed and operated will be described. In a state in which the operation unit 5 is closed, the speaker 29 faces directly upward in the operation unit 5. The front cylinder part 30 and the rear cylinder part 31 are in a positional relationship facing directly above on the center line of the speaker 29. The operation portion hole 34 and the through hole 35 are in a positional relationship close to the center line of the speaker 29. When the top panel operation button 37 of the top plate 2 is operated in the state where the operation unit 5 is closed for cooking or during cooking, the control circuit 9 guides from the speaker 9 by voice to confirm the operation. Since the operation unit 5 is closed, when the top surface re-operation button 38 is pressed, the guide finally notified from the speaker 29 is notified again.

  The sound emitted from the speaker 29 reaches the upper part of the operation unit 5 via the front tube part 30, but the sound is difficult to reach the operator because the operation part 5 is housed in the main body 1. Sound emitted below the speaker 29 is dissipated outside the main body 1 from the operation hole 34 through the through hole 35 via the rear cylinder 31. Since the operator is located in the vicinity of the operation unit 5, the sound radiated from the through hole 35 near the operation unit 5 reaches the operator. In addition, since the speaker 29, the rear cylinder part 31, the operation part hole 34, and the through hole 35 are substantially in a straight line, the sound attenuation is small and a loud sound reaches the operator, and the sound passes through the hole and is clear. Sound will be transmitted.

  When the operation unit 5 is closed, as described above, the sound from the speaker 29 attenuates the sound from the front of the speaker 29 in the operation unit 5, but the sound from the rear of the speaker 29 is transmitted to the speaker 29, the rear tube unit 31, and so on. Since the operation portion hole 34 and the through hole 35 are located on a straight line, the sound from the rear of the speaker 29 reaches the operator from the lower surface of the main body 1 with only a small attenuation. On the other hand, when the operation part 5 is open, the sound from the front part of the speaker 29 passes through the front cylinder part 30 and reaches the operator via the operation surface.

  The sound from the back of the speaker 29 passes through the operation part hole 34 through the rear cylinder part 31. However, since the operation part hole 34 is off the straight line of the speaker 29, the operation part 5 receives sound from the lower part of the main body 1. Attenuation is greater than when closed. The sum of the sound from the upper surface of the operation unit 5 and the sound from the lower surface of the operation unit 5 reaches the operator, and the sound volume and clarity when the operation unit 5 is opened and closed are the same regardless of whether the operation unit 5 is opened or closed. Can be maintained at level.
