BEST MODE FOR CARRYING OUT THE INVENTION Embodiment 1. FIG. 1 shows a perspective view showing a schematic configuration of an electric heating cooker according to an embodiment of the present invention. In the electric heating cooker 1 shown in the figure, a top plate 4 is arranged on a top surface 3 of a main body 2. A left heating portion 5a, a right heating portion 5b, and a central heating portion 5c, which can heat an object to be heated by a heating coil by placing the object to be heated on the top plate 4, are provided respectively.

Further, the top surface 3 has a frame 6 provided along the outer periphery of the top plate 4, and an intake port for taking in an air flow inside the main body 2 is provided at the back of the top surface 3 of the main body. ing. The portion corresponding to the intake port is provided with an intake filter 7 which constitutes a part of the frame 6 and prevents foreign matter from entering the main body 2 through the intake port.

Further, a roaster 9 is provided on the left side of the front side surface 8 of the main body 2, and a retractable knob 10 for adjusting the heating output of each heating portion 5a, 5b, 5c is provided on the right side of the side surface 8. And an operation unit 12 provided with an operation panel 11 provided with a timer for adjusting the heating output of the roaster 9, adjusting the power supply of the electric heating cooker 1, and setting and measuring the cooking time. ing. Then, on the front side of each of the heating parts 5a, 5b, 5c, projection windows 13a, 13 for a transmitting part for projecting and displaying the output control status of the heating coil are displayed.
b and 13c are provided respectively.

FIG. 2 is a sectional view showing a schematic structure of the transmitter of this embodiment. As shown in the figure, a heating coil 14a is provided below the top plate 4 of the heating portion 5a, and is configured to heat an object to be heated 15 placed on the heating portion 5a. A transmitter 16a is provided below the projection window 13a.

The transmitter 16a displays the case 17, the LED 18 disposed inside the case, and the heating output status of the heating coil projected and displayed in an enlarged manner in order to appropriately display an image on the surface of the object to be heated 15, Further, it is composed of a magnifying and projecting means 19 mainly composed of an optical system which can adjust the focal length and the like. In addition, here, the heating portion 5a
Transmitting unit 1 for projecting an image on the object 15 to be heated placed on
Although the description has been given using 6a, the transmitter 16 for projecting an image on the object to be heated 15 placed on the heating parts 5b and 5c.
b and 16c are also configured similarly to the transmitting unit described here.

FIG. 3 shows a display example of an image projected and displayed by the transmitting unit 16a. In the present embodiment, the power of the heating cooker 1 is turned on in the operation unit 12, the object to be heated 15 is placed on the heating portion 5a, and the heating coil 14a is set to the operable state (the power of the heating coil 14a is turned on). Then, the transmission unit 16a projects a green image of a flame on the surface of the object to be heated 15.

The knob 10 is used to heat the heating coil 14.
When the output of a is increased, the color of the projected flame image is sequentially changed from green to red from the left, and when the output is maximized, all flame images are displayed in red. It is like this. Here, the number of red flames is proportional to the heating output of the heating coil.

By projecting an image proportional to the heating output by the heating coil on the surface of the object to be heated in this way, it is possible to operate the heating output with a feeling similar to the image of heating by thermal heating.

Further, in the present embodiment, the projected flame image is projected as if the output of the heating coil becomes weak or more (being heated by the heating coil) in order to bring it closer to the image of actually using fire. The flashing image is displayed.

Further, as a method of approaching an image using such a fire, not only blinking display but also
It is also possible to change the color to a different color, change the intensity of the projected light, or use a magnifying projection means to display the flame as if it were shaking. In addition, blinking display,
If a method of changing to a different color, changing the intensity of projected light, etc. is adopted, it suffices to simply irradiate the surface of the object to be heated with light. The image does not have to be an image, and even when the image is projected, the image is not limited to an image of a flame. Further, the magnifying and projecting means 19 may be operated to change the size of a projected image such as a flame in proportion to the heating output by the heating coil. Even with such a configuration, it is possible to operate the heating output with a feeling close to the image of heating due to heating by heating.

As shown in the figure, in the electric heating cooker 1 according to the present embodiment, the information input from the operation unit 12 is sent to the control unit 20 which controls the operation of the electric heating cooker 1. When it is input from the operation unit 12 that any one of the heating coils 14a, 14b, and 14c is operated, the control unit 20 operates the operation applicable heating coil 14 based on the input information to perform the operation applicable heating. While operating the transmitting unit 16 which projects and displays on the part to be heated,
The magnifying and projecting means 19 is driven so that the heating condition can be favorably projected onto the object to be heated.

The pot or the like to be heated placed on the heating portion has various sizes such as its diameter. For this reason, in the present embodiment, the transmission unit 1 is included in the magnifying projection unit 19.
An autofocus function that measures the distance from 6 to the surface of the object to be heated and adjusts the focal length is incorporated. By having the autofocus function in this way, it becomes possible to reduce restrictions on the size of the object to be heated.

As described above, according to the electric heating cooker of the present invention, since the state of the heating output of the heating coil 14 can be approximated to the feeling of the heating output due to the heating by having the transmitter, the heating output can be adjusted. It will be easier to do. Further, since the transmitter is provided on the top surface of the main body, it is possible to display the heating output which is easy for the user to see.
