[0002] At present, there are many kinds of heating, frying and grilling utensils, including utensils for making western-style simple meals. Among them, western-style simple meals include sandwiches, hamburgers, etc. With the diversification of modern life, more and more commercial restaurants or families like to make western-style simple meals.
[0003] The Western-style simple meal device in the prior art generally uses a conductive copper tube or a conductive copper wire for heating. The specific structure is generally to set a conductive copper tube or a conductive copper wire on the back of a stainless steel pressing mold, and the conductive copper tube or the conductive copper wire is connected to a power source to generate heat, and then the conductive copper tube or the conductive copper wire transfers the heat to the stainless steel pressing mold, and the stainless steel pressing mold is then used to press the Western-style simple meal. However, the prior art method of heating with a conductive copper tube or a conductive copper wire not only consumes a lot of power, but also has poor heating uniformity. The heat near the conductive copper tube or the conductive copper wire will be higher, and the heat far away from the conductive copper tube or the conductive copper wire will be lower.
[0004] In addition, since the main principle of the Western-style fast food device in the prior art is a conductive copper tube or conductive copper wire, and a stainless steel pressing mold, the cost of the overall material is relatively high, which leads to the high cost of the Western-style fast food device in the prior art.
[0005] In addition, since the prior art western-style simple meal device uses a conductive copper tube / copper wire and a stainless steel pressing mold, these materials are relatively heavy, thereby making the overall weight of the prior art western-style simple meal device relatively heavy.

[0009] Among them, since the upper baking tray and the lower baking tray are both made of a thermally conductive insulating layer, a heating film layer and a thermally insulating layer that are bonded or pressed in sequence, the forming performance of the upper baking tray and the lower baking tray is very good and it is easy to form a mold cavity. Compared with the upper baking tray and the lower baking tray made of stainless steel in the prior art, the process of forming the mold cavity is simpler and the cost of forming the mold cavity is lower.

And / or
[0020] In the structure in which the upper baking tray and the lower baking tray are slidably connected by a guide rail, the handle is arranged in the middle of the upper surface of the upper baking tray. The handle is arranged in the middle of the upper surface of the upper baking tray, so that the upper baking tray and the lower baking tray can be opened and closed by pulling or pushing the upper baking tray up and down along the guide rail by the handle.

Among them, silver paste conductive strips or carbon paste conductive strips are first printed on the upper surface of the conductive layer, so that the conductive paste coating formed by the silver paste or carbon paste can be closely attached to the conductive layer of the polymer substrate to form a continuous electrode with stronger bonding force.

In this embodiment, the shape of the mold cavity 3 is a triangle, so that triangular simple western-style meals can be prepared, for example, triangular sandwiches can be prepared.
[0055] In this embodiment, Figure 3 As shown, the upper baking tray 1 includes a thermally conductive insulating layer 4, a heating film layer 5 and a thermally insulating layer 6 which are sequentially bonded or pressed from bottom to top; the lower baking tray 2 includes a thermally conductive insulating layer 4, a heating film layer 5 and a thermally insulating layer 6 which are sequentially bonded or pressed from top to bottom. Since the thermally conductive insulating layer 4 of the upper baking tray 1 and the thermally conductive insulating layer 4 of the lower baking tray 2 are arranged relatively to each other, it is convenient to transfer heat to the Western-style simple meal in the mold cavity 3. Among them, the bonding structure is bonded by a thermally conductive adhesive layer. Among them, the thermally conductive insulating layer 4, the heating film layer 5 and the thermally insulating layer 6 are bonded together by a thermally conductive adhesive layer, which is easy to operate and can make the heat generated by the heating film layer 5 be well transferred to the opposite sides of the upper baking tray 1 and the lower baking tray 2. Among them, the pressed structure is realized by heating and pressing.
[0056] Among them, since the upper baking tray 1 and the lower baking tray 2 are both made of a thermally conductive insulating layer 4, a heating film layer 5 and a thermally insulating layer 6 that are bonded or pressed in sequence, the upper baking tray 1 and the lower baking tray 2 have very good forming performance and are easy to form the mold cavity 3. Compared with the upper baking tray and the lower baking tray made of stainless steel in the prior art, the process of forming the mold cavity 3 is simpler and the cost of forming the mold cavity 3 is lower.
[0057] Among them, the heat-conducting insulating layer 4, on the one hand, plays a role of heat conduction, thereby transferring the heat emitted by the heating film layer 5 to the western-style meal in the mold cavity 3 for heating food, and on the other hand, plays an insulating role, thereby preventing the current in the heating film layer 5 from being transferred to the surface of the upper baking tray 1 or the lower baking tray 2, thereby avoiding the risk of electric shock to the human body during the use of the western-style meal preparation device. Among them, the heating film layer 5 can generate heat by electric heating, and the generated heat is transferred to the relative surfaces of the upper baking tray 1 and the lower baking tray 2 through the heat-conducting insulating layer 4, thereby being used to heat the food in the mold cavity 3.

On the other hand, the heat-insulating insulating layer 6 can play an insulating role, thereby ensuring that the current generated by the heating film layer 5 will not be transferred to the back of the upper baking tray 1 and the lower baking tray 2, thereby avoiding the risk of electric shock to the human body.
[0058] Among them, the heating film layer 5 is connected to an external current through a wire 53, and then transmitted to the heating film layer 5. After receiving the current, the heating film layer 5 generates heat and generates heat. The heat is then transmitted to the relative surfaces of the upper baking tray 1 and the lower baking tray 2 through the thermal conductive insulation layer 4.
[0059] The utility model discloses a device for preparing western-style light meals. Since the upper baking tray 1 and the lower baking tray 2 are both made of a heat-conducting insulating layer 4, a heating film layer 5 and a heat-insulating insulating layer 6 which are sequentially bonded or pressed together, the heat generated by the conductive heating of the heating film layer 5 is transferred to the relative surfaces of the upper baking tray 1 and the lower baking tray 2, and a heating temperature within 350°C can be achieved. Moreover, since the heating film layer is used for heating, the device has the advantages of good heating uniformity, can be connected to a voltage of 24V to 220V, has a wide voltage range and can adjust the heating temperature, and has the advantages of thin thickness, light weight and low production cost.
[0060] In practical applications, when making sandwiches, the voltage is adjusted so that the heating temperature of the upper baking tray 1 and the lower baking tray 2 is 160° C. to 190° C., thereby facilitating the making of sandwiches.

[0063] In this embodiment, Figure 6 As shown, the heating film layer 5 includes a conductive layer 51, two metal strips 52 arranged at both ends of the upper surface of the conductive layer 51, two outwardly extending wires 53 respectively welded to the two metal strips 52, and plugs 54 respectively connected to the two wires 53. Among them, the metal strips 52 include copper strips, silver strips, and aluminum strips. The metal strips 52 are used to transmit current. The metal strips 52 are directly attached and contacted to the surface of the conductive layer 51, and can transmit the current of the metal strips 52 to the conductive layer 51. The plug 54 is used to directly connect to the power supply, and then the current is transmitted to the metal strips 52 through the wires 53, and then transmitted to the conductive layer 51. After the conductive layer 51 receives the current, the entire conductive layer 51 can generate heat and generate heat, and the heat is then transmitted to the food in the mold cavity 3 through the thermal insulation layer 4.
[0064] Among them, the conductive layer 51 includes a polymer substrate and a conductive substance dispersed in the polymer substrate; wherein the polymer substrate includes liquid crystal polymer, polyphenylene ether, polyphenylene sulfide, polyimide, polyetheretherketone, polyetherketoneketone, has the characteristics of high temperature resistance, and is easy to disperse the conductive substance, so that the conductive effect of the entire conductive layer 51 is good.
[0065] The conductive material includes carbon nanotubes, graphene or conductive carbon black, which have both good dispersibility and good conductivity.

[0070] In practical applications, the thickness of the heat-conducting insulating layer 4 can be in the range of 0.01 mm to 2 mm. The heat-conducting insulating layer 4 of this thickness can ensure good thermal conductivity and insulation as well as good processing operability.
[0071] Example 2
[0072] A preparation device for a simple western-style meal in this embodiment, such as Figure 4 The difference between this embodiment and the first embodiment is that the shape of the mold cavity 3 is circular, so that a circular western-style simple meal can be prepared, for example, a circular hamburger.
[0073] Of course, in practical applications, the shape of the mold cavity 3 can also be square, rectangular, oval or animal-shaped. Different shapes of the mold cavity 3 can prepare Western-style simple meals of different shapes.
[0074] Example 3
[0075] A preparation device for a simple western-style meal in this embodiment, such as Figure 5 As shown, the Western-style simple meal preparation device of this embodiment is different from Example 1 in that the upper baking tray 1 further includes a substrate layer 7, which is attached or pressed to one side of the heat-conducting insulating layer 4 and one side of the heat-insulating layer 6; the lower baking tray 2 further includes a substrate layer 7, which is attached or pressed to one side of the heat-conducting insulating layer 4 and one side of the heat-insulating layer 6. The substrate layer 7 can bring a better decorative effect and has a more beautiful or more diverse appearance.
[0076] The substrate layer 7 includes one or a combination of two or more of a metal layer, a glass layer, a ceramic layer or a rock layer. The selected substrate layer 7 has good thermal conductivity.
[0077] Of course, in actual applications, the upper baking tray 1 may be provided with the substrate layer 7 only on one side of the heat-conducting insulating layer 4 or the heat-insulating insulating layer 6, and the lower baking tray 2 may be provided with the substrate layer 7 only on one side of the heat-conducting insulating layer 4 or the heat-insulating insulating layer 6. The specific arrangement of the substrate layer 7 may be arranged according to actual production needs.
[0078] Example 4
[0079] A preparation device for a simple western-style meal in this embodiment, such as Figure 7As shown, the difference between this embodiment and embodiment 1 is that the heating film layer 5 includes a conductive layer 51, a silver paste conductive strip or a carbon paste conductive strip 55 arranged at both ends of the upper surface of the conductive layer 51, and two metal strips 52 arranged on the upper surface of the silver paste conductive strip or the carbon paste conductive strip 55, two outwardly extending wires 53 respectively welded to the two metal strips 52, and a plug 54 respectively connected to the two wires 53. Among them, the silver paste conductive strip or the carbon paste conductive strip 55 is formed by printing silver paste or carbon paste on the conductive layer 51 and then drying it to form a stable coating structure, and then the metal strip 52 is arranged on the silver paste conductive strip or the carbon paste conductive strip 55. Among them, the plug 54 is used to directly connect to the power supply, and then the current is transmitted to the metal strip 52 through the wire 53, and then transmitted to the silver paste conductive strip or the carbon paste conductive strip 55 by the metal strip 52. Among them, silver paste conductive strips or carbon paste conductive strips 55 are first printed on the upper surface of the conductive layer 51, so that the conductive paste coating formed by the silver paste or carbon paste can be closely attached to the conductive layer 51 of the polymer substrate to form a continuous electrode with stronger bonding force. Because the formed silver paste conductive strips or carbon paste conductive strips 55 are flexible, they can be curled or bent together with the flexible conductive layer 51. However, the silver paste conductive strips or carbon paste conductive strips 55 have a relatively large resistance over a long distance, and temperature differences and unevenness problems may occur. Therefore, a metal strip 52 with extremely low resistance is arranged on the upper surface of the silver paste conductive strips or carbon paste conductive strips 55, which can compensate for the voltage loss of the silver paste conductive strips or carbon paste conductive strips 55 and reduce the temperature difference and unevenness problems. At the same time, compared with the conductive coating of the silver paste conductive strips or carbon paste conductive strips 55 formed by silver paste or carbon paste, it is more convenient to further connect the external wire 53 through the metal strip 52.
