Referring to FIG. 1, the multi-purpose roaster 100 includes an upper case 110 and a lower case 120 that constitute the overall appearance of the device. One side of the upper case 110 is provided with an input unit 131 for inputting selectable information or a control signal and a display unit 132 for outputting visual information, respectively.

The upper case 110 may include a transparent window 112 to view the inside. The window 112 makes it possible to visually check the cooking state of the object.

The upper case 110 is formed to be opened and closed in a vertical direction with respect to the lower case 120. For this purpose, the upper case 110 and the lower case 120 are connected to the hinge 117 (see FIG. 3) disposed at one side. Is connected. A handle 113 may be attached to one side of the upper case 110 to open or close the upper case 110.

The lower case 120 is provided with a cable 105 for receiving power from the outside. The cable 105 may be formed in a plug type so as to be inserted into the lower case 120, or may be directly connected to the lower case 120. In the former case, a device for converting power may be provided separately from the multi-use griller 100, and in the latter case, a device for converting power may be provided inside the lower case 120.

A support leg 121 is attached to the bottom surface of the lower case 120 so as to support the lower case 120. The supporting leg 121 may be an insulating material having a high coefficient of friction to prevent slippage, and may have a protruding length so that the lower case 120 may maintain a predetermined gap with respect to the bottom surface.

The input unit 131 is formed to control the temperature of the multi-purpose roaster 100. The input unit 131 may be configured to include a plurality of buttons. In addition, the input unit 131 may be formed in the form of a wheel or a touch button that can be manipulated.

The display unit 132 outputs the temperature input state and the measured temperature by the input unit 131. The display unit 132 may be formed by forming a liquid crystal display or LCD on a portion of the multi-purpose griller 100, an electronic paper (e-Paper) laminated with a planar heating element 141, 142 (see FIG. 3), or a group of light emitting means. Can be implemented. Specifically, according to FIG. 1, the input unit 131 and the display unit 132 are disposed on the inclined side surface of the upper case 110. The arrangement of the input unit 131 and the display unit 132 may provide convenience for use while inputting the main surface of the upper case 110 which is translucent as the window 112.

Figure 2 is a perspective view showing a state in which the multi-purpose roaster of Figure 1 is open. As shown in FIG. 2, the upper case 110 is connected to open and close with respect to the lower case 120. The upper case 110 and the lower case 120 are formed to have an accommodation space (S) therein. As one example, the upper case 110 and the lower case 120 may be formed in the form of a clamshell (clamshell).

In the receiving space S, an object that can be baked through the multi-purpose roaster 100 according to the present invention, that is, an egg E is arranged as such an example in FIG. 2. The object heated through the multi-purpose roaster 100 may vary, and in some cases, may be used for cooking purposes or for drying purposes. In order to apply heat to the egg (E), a planar heating element is disposed in the upper case 110 and the lower case 120. The arrangement and configuration of the planar heating elements disposed on the upper case 110 and the lower case 120 will be described in detail with reference to FIGS. 3 and 4.

3 is a cross-sectional view taken along line III-III of the multipurpose griller of FIG. Referring to FIG. 3, planar heating elements are disposed on the inner surface of the upper case 110 and the inner surface of the lower case 120 to heat the object E placed in the accommodation space S, respectively. In detail, the planar heating element may include a first planar heating element 141 disposed on an inner surface of the upper case 110 and a second planar heating element 142 disposed on an inner surface of the lower case 120. The first planar heating element 141 and the second planar heating element 142 may be attached in parallel to the main surface of the upper case 110 and the main surface of the lower case 120, which are the side and the lower case of the upper case 110. It is also possible to extend to the side of the 120. Detailed configurations of the planar heating elements 141 and 142 will be described later with reference to FIG. 4.

Referring again to FIG. 3, between the first planar heating element 141 and the upper case 110 and the second planar heating element 142 to minimize the leakage of heat generated by the planar heating elements 141 and 142 to the outside. Insulation layers 151 and 152 are disposed between the lower cases 120, respectively. These heat insulating layers 151 and 152 may be formed by an aerogel. Aerogel is a next-generation material with the lowest density, high heat insulation and eco-friendliness, and is composed of coarsely entangled silica material with a thickness of 10,000 parts of hair, and minimizes the emission of heat generated by the planar heating elements (141, 142). While saving, it is possible to improve the safety of the heat of the surface of the case (110,120). In particular, the heat insulation layer 151 disposed between the first surface heating element 141 and the upper case 110 may be formed to be transparent.

Protruding jaw 114 may be formed on the edge of the upper case 110 so that the upper case 110 and the lower case 120 minimize the leakage of the opening of the accommodation space (S), the protruding jaw 114 Correspondingly, an edge groove 123 into which the protruding jaw 114 is inserted may be formed at the edge of the lower case 120. The protruding jaw 114 and the edge groove 123 may be additionally provided with a packing ring.

One side of the lower case 120 is provided with an overpressure releasing unit 124 for releasing the overpressure when the pressure in the receiving space (S) exceeds the reference value. The overpressure releasing unit 124 may include a valve structure that opens only for pressure above a reference value. Accordingly, when the overpressure release unit 124 is operated, the receiving space (S) is in communication with the outside. The overpressure release part 124 may be installed in the upper case 110 instead of the lower case 120.

4 is a cross-sectional view for showing the configuration of a planar heating element according to the present invention. According to FIG. 4, the planar heating elements 141 and 142 are formed in a thin film form, and are capable of generating heat by being supplied with electric energy. Specifically, the planar heating elements 141 and 142 include a base layer 141-1, a carbon nanotube layer 141-2, and a protective layer 141-3.

The base layer 141-1 serves to support the carbon nanotube layer 141-2 during the manufacturing process. The base layer 141-1 may be formed in the form of a flexible film to bend along a curved shape. The base layer 141-1 may be formed of a resin-based resin or the like with little modification due to heat generation of the carbon nanotube layer 141-2.

The carbon nanotube layer 141-2 may be formed in a form in which carbon, in particular, carbon nanotubes (CNTs) are attached to the base layer 141-1. Carbon nanotubes have a hexagonal shape consisting of six carbons connected to each other to form a tubular shape. The electrical conductivity of carbon nanotubes is 100 to 1000 times better than copper, the thermal conductivity is the same as the best diamond in nature, and the strength is 100 times better than steel. Carbon fiber can be broken by only 1% deformation, while carbon nanotubes can withstand 15% deformation. In addition, carbon nanotubes have excellent exothermic properties.

The carbon nanotube layer 141-2 including the carbon nanotubes thus has a large amount of far-infrared emission, so that the carbon nanotube layer 141-2 may have an ingredient beneficial to health in the process of cooking an object in the receiving space S. Furthermore, the carbon nanotube layer 141-2 has a merit that the generation of electromagnetic waves is remarkably low, thereby making up for the disadvantages of the existing heater.

The protective layer 141-3 is a layer for protecting the carbon nanotube layer 141-2 from being directly exposed to the outside, and serves as a waterproofing function of the carbon nanotube layer 141-2. The protective layer 141-3 may be formed of a resin-based resin that is thin enough and heat resistant to maintain a constant thermal conductivity.

The planar heating elements 141 and 142 are thin laminates having a plurality of layers and may be formed to be transmissive as a whole. Here, 'translucent' is a concept including translucent as well as combat light, and includes an opaque part in some regions of the planar heating elements 141 and 142.

5 is a view illustrating an example of a user interface by an input unit and a display unit related to the present invention. As illustrated in FIG. 5, the display unit 132 may be configured to output various information including information 132a related to a cooking item, information 132b related to a current temperature, information 132c related to the remaining time, and the like. .

The information 132a related to the cooking item is a list of various items that can be cooked or dried through the multi-purpose griller 100, such as grilling eggs, crucian carp, grilling fish, or drying vegetables, and the like. It may include a cursor or a pointer to be selected by the.

Information 132b related to the current temperature outputs the current temperature of the accommodation space S in numerical or graphical form.

When cooking is started with respect to the selected cooking item, the display unit 132 may be configured to output the remaining time in numerical or graphic form 132c.

In addition, the display unit 132 may be configured to output information related to operations of the planar heating elements 141 and 142, an input standby state, or a cooking completion state.

6 is a block diagram of a multi-purpose grilling machine according to the present invention. As illustrated in FIG. 6, the multi-purpose griller 100 may include a controller 180, a power supply unit 181, an input unit 131, a temperature sensor 182, a humidity sensor 183, a smoke sensor 184, and opening and closing. The sensor 185, the load sensor 186, the voice output unit 187, the planar heating elements 141 and 142, and the display unit 132 may be included. However, not all of these elements are necessary and may be configured in different combinations in some cases.

The controller 180 controls the operation of the planar heating elements 141 and 142, and thus may be referred to as a heat controller. The controller 180 provides various functions under the control of various input / output means connected thereto.

The power supply unit 181 supplies power suitable for the rated current consumption and voltage of the planar heating elements 141 and 142. The power supply unit 181 may directly use a home power source or may include a rechargeable battery, and may further include a solar cell as a power generation source. In addition, the power supply unit 181 may be configured to receive power from a wireless power supply device, for example, a contactless charging device and the like to supply the device.

The input unit 131 is implemented in an operable form, and receives an input signal related to the operation of the multipurpose cooker 100 and provides it to the controller 180. The input unit 131 may be implemented in a form of a dial operation, a touch operation, a click operation, or the like. In order to improve a user interface, the input unit 131 may be implemented to be directly associated with the display unit 132. As one example, the display unit 132 may be in the form of a touch screen.

The temperature sensor 182 may be mounted to measure the temperature of the planar heating elements 141 and 142 or to measure whether the planar heating elements 141 and 142 are overheated. The controller 180 controls whether power is supplied to the planar heating elements 141 and 142 according to the temperature detected by the temperature sensor 182.

The humidity sensor 183 is configured to detect the cooking state of the object by humidity. When it is detected that the cooking or drying is completed by the humidity sensor 183, the controller 180 stops supplying power to the planar heating elements 141 and 142. On the contrary, in the case where the cooking object requires a certain degree of humidity, if the receiving space S has a humidity of a predetermined value or less, the humidity sensor 183 detects it and applies it to the controller 180. The controller 180 may control to output an alarm for replenishing water by the display unit 132 or the voice output unit 187.

The smoke sensor 184 detects whether an object in the accommodation space burns and applies a signal to the controller 180. If the smoke concentration is higher than a predetermined value by the smoke sensor 184, the controller 180 may determine that the object is burning and stop the operation of the planar heating elements 141 and 142 and take a follow-up action.

The open / close sensor 185 is configured to detect whether the upper case 110 is opened or closed. The opening / closing sensor 185 checks whether the upper case 110 is closed. When the upper case 110 is open, the opening / closing sensor 185 blocks the supply of power to the planar heating elements 141 and 142 to prevent inadvertent safety accidents. have.

The load sensor 186 detects whether an object is located in the accommodation space S. If the planar heating elements 141 and 142 are heated in the no-load state without an object, the load sensor 186 may block them by detecting them in advance.

As described above, the planar heating elements 141 and 142 may be implemented in the form of a thin carbon nanotube film, and are heated through the control of the controller 180 to provide heat for roasting or drying eggs and fish.

The voice output unit 187 receives an electrical signal and outputs an alarm signal or a reproduction sound of the media.

The display unit 132 outputs visual information related to the operation of the multipurpose griller 100. The information output by the display unit 132 may be formed in the form of numbers, letters, symbols, or icons. Instead of the display unit 132 may be implemented by a lamp that can be blinking.

In addition to the multi-purpose roaster 100 may include a radio receiver. The radio receiver is a module dedicated to receive an FM or AM radio broadcast signal, and allows a user around the multipurpose griller 100 to directly listen to the radio broadcast by the voice output unit 187. In order to receive a radio radio signal, the antenna may be realized by patterning a carbon nanotube portion of a conductive planar heating element in one form.

7A and 7B illustrate examples of applying a color change layer to a transparent planar heating element as an example related to the present invention.

According to these drawings, since the translucent planar heating element 141 may be difficult to check whether the heat is generated, the color is changed according to the temperature of the planar heating element 141 on one side of the transparent upper case 110 or the planar heating element 141. The color change layer 190 printed by the temperature sensitive ink may be formed. Such temperature-sensitive inks may be applied with known means.

The color change layer 190 provides a constant visual effect or information according to the degree of heating of the planar heating element 141. As an example, the color change layer 190 is configured to display warning information such as image caution due to a certain color change when the planar heating element 141 generates heat in a state where the color change layer 190 does not have a color or is implemented by green or the like (FIG. 7A). This can be done (FIG. 7B). The color change layer 190 may provide specific information through letters or symbols.

So that the object can be baked easily.

The grids 261 and 262 may have different shapes or combinations depending on the type of object. Specifically, according to FIG. 8, the grid frames 261 and 262 may include a first lattice frame 261 disposed on the lower case 220 and a second lattice frame 262 disposed on the upper case 210. Can be. First and second grooves 261a and 262a and second shape grooves 261b and 262b are formed in the first grid frame 261 and the second grid frame 262, respectively. The first shape grooves 261a and 262a and the second shape grooves 261b and 262b are formed to be suitable for different types of objects, respectively. That is, the first shape grooves 261a and 262a may be used for the purpose of locating eggs having a predetermined size or tubers such as potatoes or sweet potatoes. The first shape grooves 261a and 262a may be formed in the form of through holes so as to accommodate eggs or tubers of various sizes.

The second shape grooves 261b and 262b are, for example, when grilling crucian carp, the grid frames 261 and 262 are formed in a mold shape so as to have a specific shape while the dough Q is baked.

As such, the first shape grooves 261a and 262a and the second shape grooves 261b and 262b having different shapes may be provided in one lattice frame 261 and 262. However, as shown in Figure 9a, when baking eggs or tubers, the second grid 262 may be omitted.

Referring to FIG. 10, the versatile roaster 300 shows that the planar heating element 341 is disposed in the lattice frame 360. That is, the lattice frame 360 is a planar heating element 341 in the form of a lattice frame body 361 and a lattice frame body 361 formed along the shape of the lattice frame body 361 so as to partition the object (E). Has Each of the upper case 310 and the lower case 320 may include heat insulation layers 351 and 352 to prevent leakage of heat generated by the planar heating element 341. The heat insulation layers 351 and 352 may be formed by an airgel as described above. According to this example, since the heat transfer path is shortened from the planar heating element 341, the object E seated in each shape groove can increase energy efficiency during roasting or drying.
