That is, when the user manipulates the control unit 140, the control unit 140 transmits an operation signal, and a plurality of electrical components are operated by the operation signal to control the operation of the main body 100. You will cook food.

A front frame 112 supporting the case 110 and the door 120 is provided at the front end of the main body 100. The front frame 112 is a portion corresponding to the front surface of the cavity 200 to be opened and the portion where the control unit 140 is located is formed in the open form, the door 120 and the control unit 140 Is fitted.

In addition, the main body 100 has a rear exterior is formed by the rear cover 114, the rear cover 114 is fastened with the case 110 while being made in the form of a square plate having a predetermined thickness of the case ( 110 is supported, and a plurality of ventilation holes are formed in a portion located behind the battlefield chamber 130 to provide passages through which air in the outer space of the main body 100 moves to the battlefield chamber 130. The plurality of electrical components installed in the 130 are cooled.

On the other hand, provided in the inner space of the main body 100 is formed to have a predetermined internal space, the cavity 200 in which the internal space is a cooking space is the first panel 210 to form both sides and The second panel 220 forming the rear surface, the third panel 230 forming the upper surface, and the fourth panel 240 forming the lower surface are fastened to each other to form one cavity 200.

Of course, the cavity 200 is formed of a single panel to form an internal space of a certain degree, it will be possible to be configured to provide a space in which food is cooked by this internal space, the first panel 210 ) And the second panel 220 may be integrally formed, and the third panel 230 and the fourth panel 240 may be coupled to each other.

As such, when the cavity 200 is configured to provide a space where food is cooked by the internal space while forming a predetermined internal space, the cavity 200 may be formed in any form. In the embodiment of the present invention, the first panel 210 and the second panel 220 are fastened while forming a vertical surface, and the third panel 230 and the fourth panel 240 are fastened in the vertical direction. For example, the cavity 200 is formed in a shape that will be described.

In addition, the cavity 200 is formed to have a curvature in which at least one vertical surface is rounded to the outside of the food while providing a space where food is cooked by an internal space. At this time, the vertical surface having a rounded curvature is formed on a vertical surface other than the surface on which the first heat source 310 to be described later is supported.

In the embodiment of the present invention, for example, the second panel 220 is formed to have a curvature that is rounded to the outside, that is, the rear of the food. Of course, the first panel 210 may be formed to have a curvature that is rounded to the outside, that is, the side of the food.

In addition, the main body 100 is provided with various heat sources for cooking food located in the interior space of the cavity 200 which is a cooking space. The heat source is provided with a first heat source 310 that is mounted to be movable to the upper and lower side of the food via the rear of the food, located in the outer space of the cavity 200 to the high frequency into the interior space of the cavity 200 A second heat source 320 for dissipating and a third heat source 330 fixedly mounted in the outer space of the cavity 200 to dissipate heat into the inner space of the cavity 200 is provided.

Of course, each of the heat sources may be provided, or may be optionally provided, but the first heat source 310 and the first to reduce the cooking time and uniform heating of the food, heating suitable for the characteristics of the food Since it is preferable that both the second heat source 320 and the third heat source 330 are provided, the following embodiments will be described by way of example for each of the heat sources.

The second panel 220 forming the rear surface of the cavity 200 has a predetermined curvature and is formed in a substantially "⊃" shape when viewed from the top, and the second panel 220 is rearward. Since it is formed to have a certain curvature to round, it is possible to ensure a wider space in which the food is cooked, that is, the internal space of the cavity 200, there is an advantage that it is possible to cook bulky food.

Of course, the rear cover 114 forming the rear appearance of the main body 100 may be formed in the shape of a square plate, and may be formed to be recessed rearward as much as the portion where the second panel 220 is located. something to do.

In addition, the second panel 220 is recessed to the rear while having a predetermined curvature to secure a moving space of the first heat source 310. That is, since the second panel 220 is recessed to the rear to secure the moving space of the first heat source 310, the space formed inside the moving space of the first heat source 310 becomes larger so that the larger food is located. Being able to cook a bulky food is effective.

A second heat source 320 for cooking food may be further provided on the outer surface of the first panel 210 forming the side surface of the cavity 200 by radiating high frequency into the inner space of the cavity 200 in which the food is placed. do.

Hereinafter, the control unit 140 employing another embodiment of the present invention will be described with reference to FIG. 5, and the same description as described above will be omitted and other parts will be described.

5 is an exploded perspective view showing the configuration of a cooking appliance operating apparatus employing another embodiment of the present invention.

Behind the control panel 150 is a button panel 160, which is mounted with a plurality of the buttons 162 for transmitting a manipulation signal by the user is compressed. The button panel 160 is provided with a frame 164 supporting the button 162 while having a predetermined thickness.

The frame 164 supports the buttons 162 such that a plurality of the buttons 162 are arranged at positions corresponding to the button holes 152 formed on the front surface of the control panel 150 while maintaining a predetermined shape. do.

Therefore, when the button panel 160 is fastened to the rear of the control panel 150, the plurality of buttons 162 arranged in the button panel 160 pass through the button hole 152 and the front surface of the control panel 150 is controlled. It is positioned to protrude to some extent forward from the front of the (150).

Of course, the button 162 does not protrude forward than the front surface of the control panel 150, it is also possible that the front surface is positioned so as to form a virtual single surface with the front surface of the control panel 150.

As such, when the button panel 160 is provided, a button signal for generating an operation signal by the operation of the button 162 while contacting the rear end or the rear side of the button 162 on the front surface of the circuit board 170. The unit 164 is provided to protrude forward of the circuit board 170.

That is, when the user presses the button 162 to the rear, the rear end or the rear of the button 162 presses the button signal unit 164, and the button signal unit 164 is pressed to the circuit board. An operation signal is transmitted to the micom by a circuit printed on the 170, and a plurality of components including the first heat source 310 are operated by a program input to the microcomputer to operate in the internal space of the cavity 200. You will cook the food that is placed.

According to the operating device of the cooking appliance according to the present invention configured as described above, there is provided an operation device that does not form a coupling shaft, by the operation device minimizes the portion projecting from the front of the control unit is not intended by the user The effect that the operation of the control unit is prevented can be expected.

In addition, it is possible to expect the effect of improving the aesthetic appearance of the appearance by minimizing the portion projecting to the front of the control unit.

By such an effect, many applications will be available in the industry of manufacturing, producing, or selling cooking appliances.
