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 achieved through the upper baking tray and the lower baking tray. With the development of technology, some griddles gradually appear that replace the stainless steel heating tube and the upper baking tray with a far-infrared heating tube. This type of griddle retains the lower baking tray of the base, and the upper cover can bake food by setting a far-infrared heating tube. 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 the food. Summary 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. The upper cover assembly is rotatably connected to the base assembly. When the upper cover assembly covers 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. The upper baking tray is detachably connected to the upper shell. A metal heating element and a far-infrared heating plate are arranged in the upper shell. The metal heating element is arranged on the periphery of the far-infrared heating plate. When the upper baking tray is connected to the upper shell, the griddle can achieve the frying and grilling mode. When the upper baking tray is removed from the upper shell, the griddle can achieve the baking mode.

[0005] The griddle provided by the present application, by arranging a metal heating element and a far-infrared heating plate in the upper cover assembly, and setting the upper baking tray to be detachably connected to the upper shell, enables the griddle to have a frying and grilling mode and a baking mode. And 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 achieved through the upper baking tray. In the baking mode, the far-infrared heating plate can be turned on alone or the metal heating element can be turned on alone to heat the food by far-infrared radiation or heat radiation. The far-infrared heating plate and the metal heating element can also be turned on simultaneously to heat the food by far-infrared radiation and heat radiation simultaneously. Thus, the cooking functions of the griddle are more rich and diverse. Moreover, the far-infrared rays emitted by the far-infrared heating plate are more uniform than those of the far-infrared heating tube, so that the food can be heated more evenly. At the same time, since the metal heating element is arranged on the periphery of the far-infrared heating plate, the metal heating element will not block the far-infrared rays radiated by the far-infrared heating plate into the cooking cavity.

[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 plate is installed in the cavity, and the metal heating element is installed on a side of the reflector away from the cavity. The reflector is provided with a light-transmitting window corresponding to the far-infrared heating plate for allowing far-infrared rays to pass through.

[0007] Thus, by providing the reflector, an installation position is provided for the metal heating element. Moreover, the reflector and the upper shell enclose the cavity, providing an installation space for the far-infrared heating plate and other electronic components. Additionally, 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 due to overheating. By providing the light-transmitting window on the reflector, the far-infrared rays emitted by the far-infrared heating plate towards the cooking cavity are prevented from being blocked by the reflector.

[0008] In one embodiment, the light-transmitting window is provided as a through hole, and the upper cover assembly further includes a light-transmitting plate disposed at the light-transmitting window. The light-transmitting plate is used to block the far-infrared heating plate.

[0009] Thus, by providing the light-transmitting plate, food residues or grease splashes during cooking can be prevented from splashing onto the far-infrared heating plate and affecting the emission of far-infrared rays by the far-infrared heating plate without affecting the radiation of far-infrared rays from the light-transmitting window.

[0010] In one embodiment, the upper cover assembly further includes a temperature measuring assembly. The temperature measuring assembly passes through the far-infrared heating plate and the light-transmitting plate and contacts the upper baking tray when the upper baking tray is connected to the upper shell.

[0011] Thus, 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, enabling accurate detection of the temperature in the cooking cavity.

[0012] In one embodiment, the far-infrared heating plate includes a housing, an insulating and heat-insulating base, and a heating wire. The insulating and heat-insulating base is installed inside the housing. A temperature measuring avoidance hole is provided at the center of the insulating and heat-insulating base. The temperature measuring assembly is installed in the temperature measuring avoidance hole, and the heating wire is disposed on a side of the insulating and heat-insulating base facing the light-transmitting plate and is arranged around the temperature measuring avoidance hole.

[0013] In this way, the far-infrared rays and heat generated by the heating wire are radiated to the light-transmitting plate, and then radiated to the food in the cooking cavity. The insulating and heat-insulating base serves to mount the heating wire and provides insulation and heat insulation, preventing the heating wire from emitting far-infrared rays and heat towards the upper shell, thus avoiding losses and preventing the upper shell from getting hot. The cover shell protects the insulating and heat-insulating base and strengthens its structural strength, reducing the occurrence of the insulating and heat-insulating base cracking. By providing the temperature measurement avoidance hole, the temperature measurement component can be installed in the temperature measurement avoidance hole, facilitating the temperature measurement of the temperature measurement component.

[0014] In one embodiment, the metal heating element is an annular pipe fitting, and the perpendicular projection of the heating wire on the plane where the metal heating element is located is inside the metal heating element.

[0015] In this way, it can be ensured that the metal heating element does not block the far-infrared rays emitted by the heating wire towards the cooking cavity, and at the same time, the structure is very compact.

[0016] In one embodiment, the insulating and heat-insulating base is provided with a first heat-insulating convex ring extending towards the light-transmitting plate. The first heat-insulating convex ring is arranged around the temperature measurement avoidance hole. The heating wire is located on the outer peripheral side of the first heat-insulating convex ring, and the first heat-insulating convex ring abuts against the light-transmitting plate.

[0017] In this way, the first heat-insulating convex ring can block the far-infrared rays and heat emitted by the heating wire from being radiated to the temperature measurement component, thus avoiding the heating wire from affecting the accuracy of the temperature measurement of the temperature measurement component.

[0018] In one embodiment, the insulating and heat-insulating base is further provided with a second heat-insulating convex ring extending towards the light-transmitting plate. The second heat-insulating convex ring is arranged near the peripheral edge of the insulating and heat-insulating base. The heating wire is located on the inner peripheral side of the second heat-insulating convex ring, and the second heat-insulating convex ring abuts against the light-transmitting plate.

[0019] In this way, the second heat-insulating convex ring can block the far-infrared rays and heat emitted by the heating wire from being radiated to the cavity, thereby reducing the loss of the far-infrared rays and heat of the heating wire and avoiding the temperature in the cavity from being too high.

[0020] In one embodiment, the upper cover assembly further includes a first elastic member. The first elastic member abuts between the upper shell and the far-infrared heating plate, so that both the first heat-insulating convex ring and the second heat-insulating convex ring abut against the light-transmitting plate.

[0021] Thus, by setting the first elastic member, the first heat insulation convex ring and the second heat insulation convex ring can be made to abut against the light-transmitting plate, thereby avoiding gaps between the first heat insulation convex ring, the second heat insulation convex ring and the light-transmitting plate due to tolerances, which may cause hot air leakage. At the same time, the first elastic member can play a buffering role to prevent the problem of the light-transmitting plate cracking caused by stress concentration during thermal expansion and contraction.

[0022] In one embodiment, the housing is provided with a mounting portion, the mounting portion is provided with a first mounting hole, the upper housing is provided with a mounting post, a fastener is connected and passed through the first mounting hole and fixedly connected to the mounting post, the fastener has an end head that abuts against one side of the mounting portion, the first elastic member is sleeved outside the mounting post, and both ends of the first elastic member respectively abut against the upper housing and the mounting portion, so that the mounting portion abuts against the end head of the fastener.

[0023] In this way, the mounting post not only functions to mount the far-infrared heating plate, but also plays a role in limiting the first elastic member, with a very compact structure and convenient installation.

[0024] In one embodiment, the temperature measuring assembly includes a temperature measuring probe and a second elastic member, the temperature measuring probe passes through the housing, the temperature measuring avoidance hole and the light-transmitting plate, and the second elastic member acts on the temperature measuring probe so that the temperature measuring probe contacts the upper baking tray when the upper baking tray is connected to the upper housing.

[0025] Thus, by setting the second elastic member, the temperature measuring probe can be made to abut against the upper baking tray, thereby avoiding inaccurate temperature measurement caused by the temperature measuring probe not being able to contact the upper baking tray due to tolerances. At the same time, the second elastic member can play a buffering role to prevent the problem of the light-transmitting plate cracking caused by stress concentration during thermal expansion and contraction.

[0026] In one embodiment, a limiting plate is provided on the outer wall of the temperature measuring probe, the limiting plate is located between the housing and the light-transmitting plate, the second elastic member is sleeved outside the temperature measuring probe, and both ends respectively abut against the housing and the limiting plate.

[0027] In this way, the limiting plate can play a role in restricting the movement stroke of the temperature measuring probe, avoiding the part of the temperature measuring probe extending out of the light-transmitting plate being too long and affecting cooking when the upper baking tray is removed. At the same time, the limiting plate plays a role in limiting the installation of the temperature measuring probe to prevent the temperature measuring probe from falling off the far-infrared heating plate.

[0040] Please refer to Figures 1 to 3, this application provides a grilling machine, which includes a base assembly 200 and an upper cover assembly 100. The upper cover assembly 100 is rotatably connected to the base assembly 200. When the upper cover assembly 100 covers 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, and the upper baking tray 120 is detachably connected to the upper shell 110. 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. Thus, when the upper baking tray 120 is connected to the upper shell 110 and the upper cover assembly 100 covers the base assembly 200, the cooking cavity 201 is surrounded 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 covers the base assembly 200, the cooking cavity 201 is surrounded between the lower baking tray 220 and the upper shell 110.

[0041] A metal heating element 130 and a far-infrared heating plate 140 are provided in the upper shell 110, and the metal heating element 130 is arranged on the peripheral side of the far-infrared heating plate 140. When the upper baking tray 120 is connected to the upper shell 110, the grilling machine can achieve a grilling mode; when the upper baking tray 120 is removed from the upper shell 110, the grilling machine can achieve a baking mode. Thus, the grilling machine provided by this application has a metal heating element 130 and a far-infrared heating plate 140 provided in the upper cover assembly 100, and the upper baking tray 120 is arranged to be detachably connected to the upper shell 110, so that the grilling machine has a grilling mode and a baking mode. And 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 plate 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, and the far-infrared heating plate 140 and the metal heating element 130 can also be turned on simultaneously to heat food by far-infrared radiation and thermal radiation simultaneously, so that the cooking functions of the grilling machine are more diverse. Moreover, the far-infrared rays emitted by the far-infrared heating plate 140 are more uniform than those emitted by a far-infrared heating tube, so that the food can be heated more evenly. At the same time, since the metal heating element 130 is arranged on the peripheral side of the far-infrared heating plate 140, the metal heating element 130 does not block the far-infrared rays radiated by the far-infrared heating plate 140 into the cooking cavity 201.

[0042] 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 plate 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 corresponding to the far-infrared heating plate 140 for allowing far-infrared rays to pass through. 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 plate 140 and other electronic components. 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 avoided that the reflector 150 blocks the far-infrared rays emitted by the far-infrared heating plate 140 towards the cooking cavity 201.

[0043] Further, the reflector 150 can be a pure aluminum plate, an aluminized plate or a galvanized plate, with good reflection effect.

[0044] Further, the light-transmitting window 151 is set as a through hole. The upper cover assembly 100 further includes a light-transmitting plate 160 disposed at the light-transmitting window 151. The light-transmitting plate 160 is used to shield the far-infrared heating plate 140. In this way, by providing the light-transmitting plate 160, without affecting the radiation of far-infrared rays from the light-transmitting window 151, it is possible to prevent food residues or grease splashes during cooking from splashing onto the far-infrared heating plate 140 and affecting the emission of far-infrared rays by the far-infrared heating plate 140. Of course, in other embodiments, the reflector can also be partially light-transmitting to form the light-transmitting window.

[0045] Further, the light-transmitting plate 160 is a glass plate. The light-transmitting plate 160 is embedded in the light-transmitting window 151 or fixed to one side of the light-transmitting window 151. The glass plate has good light-transmitting effect and is easy to clean. In this embodiment, the light-transmitting plate 160 is installed on the side of the light-transmitting window 151 facing the far-infrared heating plate 140.

[0046] Further, the upper cover assembly 100 further includes a temperature measuring assembly 170. The temperature measuring assembly 170 passes through the far-infrared heating plate 140 and the light-transmitting plate 160. When the upper baking tray 120 is connected to the upper shell 110, the temperature measuring assembly 170 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 assembly 170 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 assembly 170 extends into the cooking cavity 201, so as to accurately detect the temperature in the cooking cavity 201.

[0047] Further, please refer toFigures 3 to 5 The far-infrared heating plate 140 includes a housing 141, an insulating and heat-insulating base 142, and a heating wire 143. The insulating and heat-insulating base 142 is installed inside the housing 141. A temperature-measuring avoidance hole 1423 is provided at the center of the insulating and heat-insulating base 142. The temperature-measuring component 170 is installed in the temperature-measuring avoidance hole 1423. The heating wire 143 is disposed on one side of the insulating and heat-insulating base 142 facing the light-transmitting plate 160 and is arranged around the temperature-measuring avoidance hole 1423. In this way, the far-infrared rays and heat generated by the heating wire 143 are radiated towards the light-transmitting plate 160 and then radiated to the food in the cooking cavity 201. The insulating and heat-insulating base 142 functions to install the heating wire 143 and provide insulation and heat insulation, preventing the heating wire 143 from emitting far-infrared rays and heat towards the upper shell 110 and causing losses, and also preventing the upper shell 110 from getting hot. The housing 141 functions to protect the insulating and heat-insulating base 142 and strengthen the structural strength of the insulating and heat-insulating base 142, reducing the occurrence of fragmentation of the insulating and heat-insulating base 142. By providing the temperature-measuring avoidance hole 1423, the temperature-measuring component 170 can be installed in the temperature-measuring avoidance hole 1423, facilitating the temperature measurement by the temperature-measuring component 170.

[0048] In this embodiment, the temperature-measuring avoidance hole 1423 is provided at the center of the insulating and heat-insulating base 142, so that the temperature-measuring component 170 installed in the temperature-measuring avoidance hole 1423 can detect the temperature of the central area of the upper baking tray 120 or the temperature of the central area of the cooking cavity 201, and the temperature measurement is more accurate. The temperature-measuring avoidance hole 1423 is set as a circular hole, but is not limited thereto. The temperature-measuring avoidance hole 1423 can also be square or other shapes.

[0049] Furthermore, the heating wire 143 can be an iron-chromium-aluminum or nickel-chromium alloy heating wire. The insulating and heat-insulating base 142 can be a ceramic part or a ceramic-like part. The housing 141 can be a metal housing.

[0050] In this embodiment, the heating wire 143 is wound around the temperature-measuring avoidance hole 1423 in a serpentine shape to form multiple turns, so as to be evenly distributed on the surface of the insulating and heat-insulating base 142, making the far-infrared rays emitted towards the cooking cavity 201 more evenly distributed, and thus enabling the food to be heated evenly.

[0051] Please refer to Figures 1 to 3 Furthermore, the metal heating element 130 is an annular pipe fitting, and the perpendicular projection of the heating wire 143 on the plane where the metal heating element 130 is located is inside the metal heating element 130. In this way, it can be ensured that the metal heating element 130 does not block the far-infrared rays emitted by the heating wire 143 towards the cooking cavity 201, and at the same time the structure is very compact. In this embodiment, the far-infrared heating plate 140 is circular, and the metal heating element 130 is square-annular, but is not limited thereto. In other embodiments, the far-infrared heating plate can also be square, and the metal heating element can also be circular-annular.

[0052] Please refer toFigures 3 to 5 , Further, the insulating and heat-insulating base 142 is provided with a first heat-insulating convex ring 1421 extending towards the light-transmitting plate 160. The first heat-insulating convex ring 1421 is arranged around the temperature-measuring avoidance hole 1423. The heating wire 143 is located on the outer peripheral side of the first heat-insulating convex ring 1421, and the first heat-insulating convex ring 1421 abuts against the light-transmitting plate 160. In this way, the first heat-insulating convex ring 1421 can block the far-infrared rays and heat emitted by the heating wire 143 from radiating towards the temperature-measuring component 170, thereby avoiding the influence of the heating wire 143 on the accuracy of temperature measurement of the temperature-measuring component 170. In this embodiment, the first heat-insulating convex ring 1421 is a circular convex ring and is concentric with the temperature-measuring avoidance hole 1423. However, it is not limited thereto, and the first heat-insulating convex ring can also be a square convex ring or a convex ring of other shapes.

[0053] Further, the insulating and heat-insulating base 142 is also provided with a second heat-insulating convex ring 1422 extending towards the light-transmitting plate 160. The second heat-insulating convex ring 1422 is arranged near the peripheral edge of the insulating and heat-insulating base 142. The heating wire 143 is located on the inner peripheral side of the second heat-insulating convex ring 1422, and the second heat-insulating convex ring 1422 abuts against the light-transmitting plate 160. In this way, the second heat-insulating convex ring 1422 can block the far-infrared rays and heat emitted by the heating wire 143 from radiating towards the cavity 111, thereby reducing the loss of far-infrared rays and heat of the heating wire 143 and avoiding too high temperature in the cavity 111.

[0054] In this embodiment, the heating wire 143 is located on the outer peripheral side of the first heat-insulating convex ring 1421 and on the inner peripheral side of the second heat-insulating convex ring 1422. Moreover, both the first heat-insulating convex ring 1421 and the second heat-insulating convex ring 1422 abut against the light-transmitting plate 160. Therefore, a closed cavity is enclosed by the surface of the insulating and heat-insulating base 142 facing the light-transmitting plate 160, the first heat-insulating convex ring 1421, the second heat-insulating convex ring 1422 and the light-transmitting plate 160. The heating wire 143 is arranged in this cavity. Due to the blocking effect of the insulating and heat-insulating base 142 on far-infrared rays and heat, the far-infrared rays and heat emitted by the heating wire 143 pass through the light-transmitting plate 160 and radiate towards the cooking cavity 201, so that the heat loss is less and the heating efficiency is higher.

[0055] Further, please refer to Figures 2 to 5, the upper cover assembly 100 further includes a first elastic member 180. The first elastic member 180 abuts between the upper shell 110 and the far-infrared heating plate 140, so that both the first heat insulation convex ring 1421 and the second heat insulation convex ring 1422 abut against the light-transmitting plate 160. In this way, by providing the first elastic member 180, the first heat insulation convex ring 1421 and the second heat insulation convex ring 1422 can be made to tightly abut against the light-transmitting plate 160, thereby avoiding gaps between the first heat insulation convex ring 1421, the second heat insulation convex ring 1422 and the light-transmitting plate 160 due to tolerances, resulting in hot air leakage. At the same time, the first elastic member 180 can play a buffering role to prevent the problem of cracking of the light-transmitting plate 160 caused by stress concentration during thermal expansion and contraction.

[0056] Further, please refer to Figure 2 , Figure 3 and Figure 5 , the cover 141 is provided with a mounting portion 1411. The mounting portion 1411 is provided with a first mounting hole 1412. The upper shell 110 is provided with a mounting post 112. A fastener 190 is connected and passed through the first mounting hole 1412 and fixedly connected to the mounting post 112. The fastener 190 has a head that abuts against one side of the mounting portion 1411. The first elastic member 180 is sleeved outside the mounting post 112. The two ends of the first elastic member 180 respectively abut against the upper shell 110 and the mounting portion 1411, so that the mounting portion 1411 abuts against the head of the fastener 190. In this way, the mounting post 112 not only functions to mount the far-infrared heating plate 140, but also plays a limiting role for the first elastic member 180, with a very compact structure and convenient installation. As shown in the figure, in this embodiment, the cover 141 is provided with three mounting portions 1411, and the three mounting portions 1411 are arranged in a triangle. The mounting post 112 is correspondingly arranged for the mounting portion 1411. In this way, the far-infrared heating plate 140 is firmly mounted. However, it is not limited thereto. The number of the mounting portions 1411 can also be two, four, five, six, etc.

[0057] In this embodiment, the first elastic member 180 is a compression spring, with a simple structure, good elasticity and easy installation. The fastener 190 is a screw. The mounting post 112 is provided with a second mounting hole, and the second mounting hole is provided with internal threads. The screw passes through the first mounting hole 1412 and is threadedly connected to the second mounting hole. In this way, the far-infrared heating plate 140 can be mounted on the upper shell 110.

[0058] Such as Figures 3 to 5As shown, the temperature measuring assembly 170 includes a temperature measuring probe 171 and a second elastic member 172. The temperature measuring probe 171 passes through the housing 141, the temperature measuring avoidance hole 1423, and the light-transmitting plate 160. The second elastic member 172 acts on the temperature measuring probe 171 so that the temperature measuring probe 171 contacts the upper baking tray 120 when the upper baking tray 120 is connected to the upper housing 110. In this way, by providing the second elastic member 172, the temperature measuring probe 171 can be pressed against the upper baking tray 120, thereby avoiding inaccurate temperature measurement caused by the temperature measuring probe 171 not being able to contact the upper baking tray 120 due to tolerances. At the same time, the second elastic member 172 can play a buffering role to prevent the problem of the light-transmitting plate 160 cracking caused by stress concentration during thermal expansion and contraction.

[0059] It can be understood that one end of the temperature measuring probe 171 connected to the wire passes through the housing 141. In this way, the wire can be installed in the cavity 111.

[0060] In this embodiment, the end face of the temperature measuring probe 171 facing the upper baking tray 120 is a flat surface. In this way, the temperature measuring probe 171 contacts the upper baking tray 120 more reliably, and thus the temperature measurement is more accurate.

[0061] Furthermore, a limiting plate 173 is provided on the outer wall of the temperature measuring probe 171. The limiting plate 173 is located between the housing 141 and the light-transmitting plate 160. The second elastic member 172 is sleeved outside the temperature measuring probe 171, and both ends respectively abut against the housing 141 and the limiting plate 173. In this way, the limiting plate 173 can play a role in limiting the movement stroke of the temperature measuring probe 171, avoiding that when the upper baking tray 120 is removed, the length of the part of the temperature measuring probe 171 extending out of the light-transmitting plate 160 is too long and affecting cooking. At the same time, the limiting plate 173 plays a role in limiting the installation of the temperature measuring probe 171 to prevent the temperature measuring probe 171 from falling out of the far-infrared heating plate 140.

[0062] In this embodiment, the second elastic member 172 is a compression elastic member, with a simple structure and good elasticity.

[0063] As Figure 1 shown, the lower baking tray 220 of the base assembly 200 can be set as a deep tray. It can be understood that a deep tray is a baking tray with a greater depth compared to a baking tray of a conventional size, and it has a larger capacity. The deep tray can not only be used for frying and grilling food, but also for cooking food. And, since the griddle includes a metal heating element 130 and a far-infrared heating plate 140, when the far-infrared heating plate 140 is turned on, its baking function is similar to that of an oven. That is to say, by providing the above-mentioned far-infrared heating plate 140, the griddle has added an oven function compared to a griddle that only heats food through the upper baking tray 120.

[0064] 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 various 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 to be within the scope described in this specification.

[0065] The above-described embodiments merely 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 modifications 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 shall be subject to the appended claims.
