Description

Technical Field

[0001] The present application relates to the technical field of cooking appliances, and particularly to a griddle. Background Art

[0002] A griddle, also known as an electric griddle, is widely loved by consumers because it has multiple functions such as frying, grilling, and baking. Traditional griddles usually include an upper baking tray and a lower baking tray, and the frying and grilling of food are realized through the upper baking tray and the lower baking tray. With the development of technology, some griddles that replace the stainless steel heating tube and the upper baking tray with far-infrared heating tubes gradually appear. This type of griddle retains the lower baking tray of the base, and the upper cover is provided with far-infrared heating tubes to realize the baking of food. However, the griddle set in this way loses the traditional frying and grilling modes, the functions become single, and the far-infrared heating tubes arranged on the upper cover are usually annular pipe fittings, and the far-infrared rays are unevenly distributed, resulting in uneven heating of food. Content of the Utility Model

[0003] Based on this, it is necessary to provide a griddle to improve the diversity of its cooking functions and the even heating of food.

[0004] A griddle includes a base assembly and an upper cover assembly. When the upper cover assembly is closed on the base assembly, a cooking cavity is formed between the upper cover assembly and the base assembly. The upper cover assembly includes an upper shell and an upper baking tray detachably connected to the upper shell. A metal heating element and a far-infrared heating assembly are provided on the upper shell. The far-infrared heating assembly includes a base and a heating core body arranged in the base. A far-infrared coating is provided on one surface of the base facing the cooking cavity. When the upper baking tray is connected to the upper shell, the griddle can realize the frying and grilling mode. When the upper baking tray is removed from the upper shell, the griddle can realize the baking mode.

[0005] The griddle provided by the present application is provided with a metal heating element and a far-infrared heating assembly on the upper cover assembly, and a detachable upper baking tray is provided, so that the griddle has a frying and grilling mode and a baking mode. In the frying and grilling mode, the metal heating element can be turned on to heat the upper baking tray, and frying and grilling are realized through the upper baking tray. In the baking mode, the far-infrared heating assembly can be turned on alone or the metal heating element can be turned on alone to heat food by far-infrared radiation or thermal radiation. The far-infrared heating assembly and the metal heating element can also be turned on at the same time to heat food by far-infrared radiation and thermal radiation at the same time, so that the baking mode is richer, and the cooking functions of the griddle are greatly expanded. Since the far-infrared heating assembly includes a heating core body and a far-infrared coating, when the heating core body works, it generates heat and excites the far-infrared coating to generate far-infrared rays. Since the far-infrared coating is provided on one surface of the base facing the cooking cavity, when the far-infrared coating is excited, a planar far-infrared ray radiation can be formed, making the far-infrared rays more evenly distributed, thereby improving the even heating of food.

[0006] In one embodiment, the upper cover assembly further includes a reflector connected to the upper shell. The upper shell and the reflector enclose a cavity, the far-infrared heating assembly is installed in the cavity, the metal heating element is installed on a side of the reflector away from the cavity, and the reflector is provided with a light-transmitting window for far-infrared rays to pass through corresponding to the far-infrared coating.

[0007] In this way, the reflector provides an installation position for the metal heating element, and the reflector and the upper shell enclose a cavity, providing an installation space for the far-infrared heating assembly and other electronic components, and preventing the far-infrared coating of the far-infrared heating assembly from contacting the upper baking tray, thereby avoiding the upper baking tray squeezing the far-infrared heating assembly during thermal expansion and contraction, resulting in wear of the far-infrared coating. Moreover, the reflector can reflect the heat emitted by the metal heating element towards the upper shell to the upper baking tray, avoiding the loss of this part of the heat and preventing this part of the heat from dissipating to the upper shell and damaging the electronic components in the cavity. By providing a light-transmitting window on the reflector, it is avoided that the reflector blocks the far-infrared rays emitted by the far-infrared heating assembly towards the cooking cavity.

[0008] In one embodiment, the metal heating element is an annular pipe fitting, and the light-transmitting window is located inside the metal heating element.

[0009] In this way, the metal heating element does not block the far-infrared rays transmitted through the light-transmitting window, and the length of the metal heating element is relatively long, which is beneficial to uniformly heating the upper baking tray.

[0010] In one embodiment, the upper cover assembly further includes a temperature measuring assembly installed on the reflector. The orthographic projection of the temperature measuring assembly on the reflector is located outside the light-transmitting window. When the upper baking tray is connected to the upper shell, the temperature measuring assembly contacts the upper baking tray.

[0011] In this way, when the upper baking tray is connected to the upper shell, the temperature measuring assembly can accurately detect the temperature of the upper baking tray; when the upper baking tray is removed from the upper shell, the temperature measuring assembly extends into the cooking cavity, so that the temperature in the cooking cavity can be accurately detected. The orthographic projection of the temperature measuring assembly on the reflector is located outside the light-transmitting window, which can avoid the direct radiation of far-infrared rays onto the temperature measuring assembly and affect the temperature measurement.

[0012] In one embodiment, the base includes a substrate and a mounting plate provided on one side of the substrate. The far-infrared coating is provided on a side of the substrate away from the mounting plate. The mounting plate and the substrate enclose an installation cavity with a side opening, and the heating core is provided in the installation cavity.

[0013] In this way, the structure of the base is very simple, and it is easy to install the heating core in the installation cavity of the base.

[0014] In one embodiment, the installation cavity is provided as one and is located in the central area of the substrate.

[0015] In this way, it is beneficial for the heating element in the installation cavity to uniformly heat and activate the far-infrared materials at various positions of the far-infrared coating, thereby forming uniform far-infrared radiation.

[0016] In one embodiment, both the installation cavity and the heating element are provided as multiple ones, and the multiple heating elements are respectively installed in the multiple installation cavities one by one.

[0017] By providing multiple installation cavities and multiple heating elements, the heating elements can heat and activate the far-infrared materials at various positions of the far-infrared coating more uniformly, thereby forming more uniform far-infrared radiation.

[0018] In one embodiment, the heating element is a PTC heating sheet or an MCH heating sheet.

[0019] The PTC heating sheet has high heat transfer efficiency, can effectively reduce power waste and is more energy-saving; moreover, the PTC heating sheet has an automatic constant temperature function and can automatically stop heating when reaching the designed temperature, so that even in case of a fault, it will not generate an excessive temperature and is safer to use; moreover, the PTC heating sheet has a long service life and is not easily affected by high temperature or long-term operation. The MCH heating sheet has high thermal efficiency and can quickly convert electrical energy into heat energy, thus rapidly raising the temperature; the MCH heating sheet has low energy consumption and can save a large amount of electrical energy; the surface temperature of the MCH heating sheet is relatively low and there are no safety hazards such as high-temperature scalding.

[0020] In one embodiment, the material of the base is ceramic or aluminum.

[0021] Ceramic or aluminum has good high-temperature resistance.

[0022] In one embodiment, the material of the far-infrared coating is graphene or binchotan.

[0023] Graphene and binchotan are very good far-infrared radiation materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Please refer to Figures 1 to 4, this application provides a griddle, which includes a base assembly 200 and an upper cover assembly 100. When the upper cover assembly 100 is closed on the base assembly 200, a cooking cavity 201 is formed between the upper cover assembly 100 and the base assembly 200. The upper cover assembly 100 includes an upper shell 110 and an upper baking tray 120 detachably connected to the upper shell 110. A metal heating element 130 and a far-infrared heating component 140 are provided on the upper shell 110. The far-infrared heating component 140 includes a base 141 and a heating core 142 disposed within the base 141. A far-infrared coating 143 is provided on a surface of the base 141 facing the cooking cavity 201. When the upper baking tray 120 is connected to the upper shell 110, the griddle can achieve a grilling mode; when the upper baking tray 120 is removed from the upper shell 110, the griddle can achieve a baking mode. The griddle provided in this application has a metal heating element 130 and a far-infrared heating component 140 provided on the upper cover assembly 100, and a detachable upper baking tray 120 is provided, so that the griddle has a grilling mode and a baking mode. In the grilling mode, the metal heating element 130 can be turned on to heat the upper baking tray 120, and grilling can be achieved through the upper baking tray 120; in the baking mode, the far-infrared heating component 140 can be turned on alone or the metal heating element 130 can be turned on alone to heat food by far-infrared radiation or thermal radiation. The far-infrared heating component 140 and the metal heating element 130 can also be turned on simultaneously to heat food by far-infrared radiation and thermal radiation at the same time, so that the baking mode is more diverse, and thus the cooking function of the griddle is greatly expanded. Since the far-infrared heating component 140 includes a heating core 142 and a far-infrared coating 143, when the heating core 142 works, it generates heat and excites the far-infrared coating 143 to generate far-infrared rays. Since the far-infrared coating 143 is provided on a surface of the base 141 facing the cooking cavity 201, when the far-infrared coating 143 is excited, a planar far-infrared radiation can be formed, so that the far-infrared rays are more evenly distributed, thereby improving the even heating of food.

[0038] In this embodiment, the upper cover assembly 100 is rotatably connected to the base assembly 200, which is convenient for opening the upper cover assembly 100, thereby facilitating grilling or baking food.

[0039] The base assembly 200 includes a lower shell 210 and a lower baking tray 220, and the lower baking tray 220 is installed on the lower shell 210. When the upper baking tray 120 is connected to the upper shell 110 and the upper cover assembly 100 is closed on the base assembly 200, a cooking cavity 201 is defined between the lower baking tray 220 and the upper baking tray 120. When the upper baking tray 120 is removed from the upper shell 110 and the upper cover assembly 100 is closed on the base assembly 200, a cooking cavity 201 is defined between the lower baking tray 220 and the upper shell 110.

[0040] In this embodiment, when the upper baking tray 120 is connected to the upper shell 110, the metal heating element 130 is in contact with the upper baking tray 120, ensuring that the metal heating element 130 can directly transfer heat to the upper baking tray 120, thus facilitating the rapid heating of the upper baking tray 120. Further, when the upper baking tray 120 is connected to the upper shell 110, the far-infrared coating 143 of the far-infrared heating assembly 140 is not in contact with the upper baking tray 120. In this way, it is possible to avoid the upper baking tray 120 squeezing the far-infrared heating assembly 140 during thermal expansion and contraction, resulting in wear or even failure of the far-infrared coating 143.

[0041] Further, the upper cover assembly 100 further includes a reflector 150 connected to the upper shell 110. The upper shell 110 and the reflector 150 enclose a cavity 111. The far-infrared heating assembly 140 is installed in the cavity 111, and the metal heating element 130 is installed on the side of the reflector 150 away from the cavity 111. The reflector 150 is provided with a light-transmitting window 151 for allowing far-infrared rays to pass through corresponding to the far-infrared coating 143. In this way, by providing the reflector 150, an installation position is provided for the metal heating element 130, and the reflector 150 and the upper shell 110 enclose the cavity 111, providing an installation space for the far-infrared heating assembly 140 and other electronic components, and avoiding the far-infrared coating 143 of the far-infrared heating assembly 140 from contacting the upper baking tray 120, thereby avoiding the upper baking tray 120 squeezing the far-infrared heating assembly 140 during thermal expansion and contraction, resulting in wear of the far-infrared coating 143. Moreover, the reflector 150 can reflect the heat emitted by the metal heating element 130 towards the upper shell 110 to the upper baking tray 120, avoiding the loss of this part of the heat and preventing this part of the heat from dissipating to the upper shell 110 and damaging the electronic components in the cavity 111 due to overheating. By providing the light-transmitting window 151 on the reflector 150, it is possible to avoid the reflector 150 blocking the far-infrared rays emitted by the far-infrared heating assembly 140 towards the cooking cavity 201.

[0042] In this embodiment, the light-transmitting window 151 is set as a through hole, so that it is possible to avoid blocking the far-infrared radiation.

[0043] Further, the metal heating element 130 is an annular pipe fitting, and the light-transmitting window 151 is located inside the metal heating element 130. In this way, the metal heating element 130 will not block the far-infrared rays transmitted from the light-transmitting window 151, and the length of the metal heating element 130 is relatively long, which is beneficial to uniformly heating the upper baking tray 120. In this embodiment, the metal heating element 130 is a square annular pipe fitting, but it is not limited thereto. In other embodiments, the metal heating element can also be a circular annular pipe fitting or an annular pipe fitting of other shapes.

[0044] Furthermore, the upper cover assembly 100 further includes a temperature measuring component 160 installed on the reflector 150. The orthographic projection of the temperature measuring component 160 on the reflector 150 is located outside the light-transmitting window 151. When the upper baking tray 120 is connected to the upper shell 110, the temperature measuring component 160 contacts the upper baking tray 120. In this way, when the upper baking tray 120 is connected to the upper shell 110, the temperature measuring component 160 can accurately detect the temperature of the upper baking tray 120; when the upper baking tray 120 is removed from the upper shell 110, the temperature measuring component 160 extends into the cooking cavity 201, so as to accurately detect the temperature in the cooking cavity 201. The orthographic projection of the temperature measuring component 160 on the reflector 150 is located outside the light-transmitting window 151, which can prevent the far-infrared rays from directly irradiating on the temperature measuring component 160 and affecting the temperature measurement. In this embodiment, the light-transmitting window 151 is arranged as a crescent-shaped through hole, and the temperature measuring component 160 is located on the concave side of the crescent-shaped through hole, with a very compact structure and beautiful appearance. Of course, in other embodiments, the light-transmitting window 151 can also be arranged in other shapes.

[0045] Please refer to Figure 5 , the base 141 includes a base plate 1411 and a mounting plate 1412 provided on one side of the base plate 1411. The far-infrared coating 143 is provided on the side of the base plate 1411 away from the mounting plate 1412. The mounting plate 1412 and the base plate 1411 enclose an installation cavity 1413 with a side opening, and the heating core 142 is arranged in the installation cavity 1413. In this way, the structure of the base 141 is very simple, and it is easy to install the heating core 142 in the installation cavity 1413 of the base 141.

[0046] Furthermore, the base plate 1411 is crescent-shaped. In this way, the structure of the base plate 1411 is very simple, and it ensures that one side of the base plate 1411 has a large area for setting the far-infrared coating 143. At the same time, the temperature measuring component 160 can be installed on the concave side of the crescent-shaped base plate 1411, so that the structure can be more compact.

[0047] Please refer to Figure 5 , in one embodiment, the installation cavity 1413 is arranged as one and is located in the central area of the base plate 1411. In this way, it is beneficial for the heating core 142 in the installation cavity 1413 to heat evenly and activate the far-infrared materials at various positions of the far-infrared coating 143, so as to form a uniform far-infrared ray radiation.

[0048] Please refer to Figure 6 , in another embodiment, both the installation cavity 1413 and the heating core 142 are arranged as multiple ones, and the multiple heating cores 142 are respectively installed in the multiple installation cavities 1413. By arranging multiple installation cavities 1413 and multiple heating cores 142, the heating cores 142 can heat and activate the far-infrared materials at various positions of the far-infrared coating 143 more evenly, so as to form a more uniform far-infrared ray radiation.

[0049] Furthermore, the heating core 142 is a PTC heating sheet or an MCH heating sheet. The PTC heating sheet has a high heat transfer efficiency, can effectively reduce the waste of electric energy, and is more energy-efficient; moreover, the PTC heating sheet has an automatic constant temperature function and can automatically stop heating when the designed temperature is reached, so that even in case of a fault, it will not generate an excessive temperature and is safer to use; furthermore, the PTC heating sheet has a long service life and is not easily affected by high temperature or long-term operation. The MCH heating sheet has a high thermal efficiency and can quickly convert electric energy into heat energy, thus rapidly increasing the temperature; the MCH heating sheet has low energy consumption and can save a large amount of electric energy; the surface temperature of the MCH heating sheet is relatively low and will not cause safety hazards such as high-temperature scalding.

[0050] Furthermore, the base 141 is made of ceramic or aluminum. Ceramic or aluminum has good high-temperature resistance.

[0051] Furthermore, the material of the far-infrared coating 143 is graphene or binchotan. Graphene and binchotan are very good far-infrared radiation materials.

[0052] Furthermore, the lower baking tray 220 of the base assembly 200 can be set as a shallow tray (not shown) or a deep tray (as shown), and it can be understood that the shallow tray and the deep tray are divided according to the depth of the baking tray. The baking tray with a shallower depth is the shallow tray, and the baking tray with a deeper depth is the deep tray. Generally, the shallow tray can only be used for grilling food and cannot be used for stewing food; while the deep tray can not only be used for grilling food but also for stewing food. Since the baking function of the far-infrared heating assembly 140 is similar to that of an oven, for a griddle with the lower baking tray 220 set as a deep tray, its capacity is similar to that of an oven. Therefore, compared with a griddle that only heats food through the baking tray, this griddle has an additional oven function. Figure 1 shown), it can be understood that the shallow tray and the deep tray are divided according to the depth of the baking tray. The baking tray with a shallower depth is the shallow tray, and the baking tray with a deeper depth is the deep tray. Generally, the shallow tray can only be used for grilling food and cannot be used for stewing food; while the deep tray can not only be used for grilling food but also for stewing food. Since the baking function of the far-infrared heating assembly 140 is similar to that of an oven, for a griddle with the lower baking tray 220 set as a deep tray, its capacity is similar to that of an oven. Therefore, compared with a griddle that only heats food through the baking tray, this griddle has an additional oven function.

[0053] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0054] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
