The operation detection device 68 detects an operation performed by the user on the first operation display surface 56. The operation detection device 68 of the present embodiment irradiates, for example, directional infrared rays from the front surface 4a of the main body 4 toward the front side along the first operation display surface 56, and an obstacle (for example, a user's finger F). It is an infrared detection device that detects infrared rays reflected by. The operation detection device 68 can detect the content of the operation on the first operation display surface 56 by detecting the position of an obstacle (for example, the user's finger F) existing in the vicinity of the first operation display surface 56. .. The operation of the operation detection device 68 is controlled by the control device 70.

The control device 70 controls the content displayed on the first operation display surface 56 by controlling the content displayed on the internal screen 64a of the liquid crystal display 64, and based on the detection signal of the operation detection device 68, the control device 70 controls the content displayed on the first operation display surface 56.

As shown by, it recognizes that an obstacle has approached the first operation display surface 56 from the side, that is, the user's body has unexpectedly interfered with the first operation display surface 56. In this way, when the operation on the operation prohibited area 72 is detected, the control device 70 prohibits the subsequent reception of the operation on the first operation display surface 56. With such a configuration, it is possible to prevent erroneous operation input from being accepted. While the control device 70 prohibits the reception of the operation on the first operation display surface 56, the control device 70 displays the color of the operation prohibition area 72 in a color different from the normal time, or repeatedly blinks the operation prohibition area 72. Informs the user that the acceptance of operations is prohibited. When the operation detection device 68 no longer detects the operation on the first operation display surface 56 in the state where the reception of the operation on the first operation display surface 56 is prohibited, the control device 70 displays the first operation thereafter. Allows acceptance of operations on surface 56. With such a configuration, when the user's body unexpectedly interferes with the first operation display surface 56, the user's body continues to interfere with the first operation display surface 56 after that. 1 Continue to prohibit acceptance of operations on the operation display surface 56, and after the user's body no longer interferes with the first operation display surface 56, resume acceptance of operations on the first operation display surface 56 as usual. Can be done. As shown in FIG. 2, the operation prohibition area 72 may be set over the entire circumference of the outer edge of the first operation display surface 56, or is set only on a part of the outer edge of the first operation display surface 56. You may. For example, the operation prohibited area 72 may be set only on the left and right edges and the front edge when the user looks at the first operation display surface 56, or may be set only on the left and right edges. ..

According to the heating device 2 of the present embodiment, the first operation display surface 56 is located in the space on the front side of the front surface 4a of the main body 4, and the lower part is located on the front side of the main body 4. It is formed so as to be inclined with respect to the front surface 4a. In this case, when the user performs an operation on the first operation display surface 56, the finger F is moved from the upper side to the lower side in the space on the front side of the front surface 4a of the main body 4. Therefore, when the user tries to operate the first operation display surface 56, the finger F is not accidentally brought close to the object to be heated such as the cooking container arranged on the upper portion of the top plate 6. According to the above configuration, the safety of the user can be ensured even when the first operation display surface 56 is imaged in the external space.
