  Embodiments of the present invention will be described below with reference to the drawings. Note that the present invention is not limited to the embodiments.

  1 and 2 are an overall cross-sectional view and a cross-sectional view of an operation unit of a built-in type cooking device according to an embodiment of the present invention.

  1 and 2, the heating apparatus main body 1 is provided with a heating chamber 2 for heating an object to be heated by a heater or heating means (not shown) such as high frequency or steam. The door 3 that opens and closes the heating chamber 2 is provided with a handle 4 at the upper center of the door and can be opened and closed by the user.

  Human body detection means 42 is provided on the inner surface of the handle 4. The electrical component 5 containing the heating means is provided at an appropriate position of the heating device main body 1. In response to an input from the operation unit 6 provided above the door of the heating apparatus main body 1, the electrical unit 5 operates the heating means and the like.

  A cooling fan motor 7 that cools the electrical unit 5 and a heating chamber exhaust fan 8 are provided inside the heating device, and an exhaust port that is discharged from the cooling fan motor 7 between the door 3 and the operation unit 6 on the front surface of the heating device. 9 is provided. The heating chamber 2 is provided with an intake port 10 of a heating chamber exhaust fan. A door switch 11 that detects opening and closing of the door 3 is also provided.

The operation unit 6 is a rotary retractable type. When the user does not use the heating device, the operation unit 6 can be rotated and stored in the storage unit 12, and when the user uses the heating device, the operation unit 6 is Rotate to use position. In order to detect this rotational position, a switch 13 is provided.

  Further, a wind direction plate 14 is provided at the lower part (back side) of the operation unit 6, and the wind direction plate 14 hangs down so as to draw an arc from the rear to the front of the operation unit 6. Moreover, since it hangs down, the operation panel 15 can be enlarged on the back surface of the wind direction board 14, and operativity is also improved.

  FIG. 3 is a cross-sectional view showing the action of the wind direction plate 14 when the door 3 is opened. As shown in FIG. 3, by the action of the wind direction plate 14, the exhaust air emitted from the cooling fan motor 7 flows from the exhaust port 9 on the front surface of the heating device into the heating chamber from above by the wind direction plate 14. The hot air from the heating chamber 2 when the door 3 is opened during heating can be suppressed and released to the user side.

  As is apparent from the above configuration, in this heating device, even when the heating user opens the door, the release of hot air from the heating chamber is reduced, so that it can be operated without user discomfort.

  Then, when the user sets the rotary operation unit to the use position, information indicating that the operation unit 6 has been taken out by the position detection switch 13 is transmitted to the electrical unit 5, thereby increasing the number of rotations of the cooling fan motor 7. The air volume from the exhaust port 9 increases, and the release of hot air from the heating chamber is suppressed.

  Further, when the user opens the door 3, the information that the door 3 has been opened is transmitted to the electrical component 5 by the action of the door switch 11, thereby increasing the number of rotations of the cooling fan motor 7 and the exhaust port 9. The amount of air from the heating chamber increases, and the release of hot air from the heating chamber 2 is suppressed.

  Further, when the user touches the door 3 in order to open the door 3, the information from the human body detection means 42 of the door handle 4 is transmitted to the electrical component 5, thereby increasing the number of rotations of the cooling fan motor 7. The air volume from the exhaust port 9 increases, and the release of hot air from the heating chamber 2 is suppressed.

  On the contrary, in the state where hot air is released from the heating chamber 2, the detection means is transmitted to the electrical component 5, and by controlling the electrical component 5, the number of rotations of the heating chamber exhaust fan 8 is reduced. By reducing the hot air itself from the chamber 2, the release of hot air from the heating chamber 2 can be suppressed.

  In the above embodiment, it goes without saying that the functions can be combined and used synergistically to reduce hot air from the heating chamber 2.

  Since the heating device of the present invention can reduce the release of heat from the heating chamber, it can be used for applications such as a microwave oven and an electric oven.
