Description

Technical Field

[0001] The present application relates to the technical field of cooking appliances, and in particular to a frying and grilling machine. Background Art

[0002] The frying and baking machine, also known as the electric baking pan, is widely loved by consumers because of its multiple functions such as frying, baking, and baking. The traditional frying and baking machine usually includes an upper baking tray and a lower baking tray, which are used to fry and bake food. With the development of technology, some frying and baking machines have gradually emerged that use far-infrared heating tubes to replace stainless steel heating tubes and upper baking trays. This type of frying and baking machine retains the lower baking tray of the base, and the upper cover is equipped with far-infrared heating tubes to bake food. However, the frying and baking machine configured in this way loses the traditional frying and baking mode, and the function becomes single, and the far-infrared heating tubes arranged on the upper cover are usually annular pipes, and the far-infrared rays are unevenly distributed, resulting in uneven heating of the food. Summary of the invention

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

[0004] A grilling machine comprises a base assembly and an upper cover assembly, wherein the upper cover assembly is rotatably connected to the base assembly, and 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 comprises an upper shell and an upper baking tray, wherein the upper baking tray is detachably connected to the upper shell, and a metal heating element and a far-infrared heating tray are arranged in the upper shell, wherein the metal heating element is arranged on the peripheral side of the far-infrared heating tray, and when the upper baking tray is connected to the upper shell, the grilling machine can realize a grilling mode; when the upper baking tray is removed from the upper shell, the grilling machine can realize a baking mode.

[0005] The grilling machine provided by the present application has a grilling mode and a baking mode by arranging a metal heating element and a far-infrared heating plate on the upper cover assembly, and the upper baking plate is arranged to be detachably connected to the upper shell, and the grilling machine has a grilling mode and a baking mode, and in the grilling mode, the metal heating element can be turned on to heat the upper baking plate, and grilling is achieved through the upper baking plate; in the baking mode, the far-infrared heating plate or the metal heating element can be turned on alone, and the food can be heated by far-infrared radiation or thermal radiation, and the far-infrared heating plate and the metal heating element can also be turned on at the same time, and the food can be heated by far-infrared radiation and thermal radiation at the same time, so that the cooking function of the grilling machine is more diverse. Moreover, the far-infrared heating plate emits more uniform far-infrared rays than the far-infrared heating tube, so that the food can be heated more uniformly. 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 from the far-infrared heating plate to the cooking cavity.

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

[0007] In this way, the reflector is provided to provide an installation position for the metal heating element, and the reflector and the upper shell are arranged in the cavity, providing installation space for the far-infrared heating plate and other electronic components, and the reflector can reflect the heat emitted by the metal heating element toward the upper shell to the upper baking plate, avoiding the loss of this part of heat, and avoiding the heat dissipation to the upper shell and causing the electronic components in the cavity to be damaged by heat. By arranging a light-transmitting window on the reflector, the reflector is prevented from blocking the far-infrared rays emitted by the far-infrared heating plate to the cooking cavity.

[0008] In one of the embodiments, the light-transmitting window is configured as a through hole, and the upper cover assembly further includes a light-transmitting plate disposed on the light-transmitting window, and the light-transmitting plate is used to shield the far-infrared heating plate.

[0009] Thus, by providing a light-transmitting plate, without affecting the radiation of far infrared rays from the light-transmitting window, it is possible to prevent food residues or grease splashing onto the far infrared heating plate during cooking and affecting the emission of far infrared rays by the far infrared heating plate.

[0010] In one of the embodiments, the upper cover assembly further includes a temperature measuring assembly, and the temperature measuring assembly is disposed through the far-infrared heating plate and the light-transmitting plate. When the upper baking plate is connected to the upper shell, the temperature measuring assembly is in contact with the upper baking plate.

[0011] In this way, when the upper baking tray is connected to the upper shell, the temperature measuring component can accurately detect the temperature of the upper baking tray; when the upper baking tray is removed from the upper shell, the temperature measuring component extends into the cooking cavity, thereby being able to accurately detect the temperature in the cooking cavity.

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

[0013] In this way, the far infrared rays and heat generated by the heating wire radiate toward the light-transmitting plate, and then radiate to the food in the cooking cavity. The insulating base serves to install the heating wire and insulate the heat, preventing the heating wire from emitting far infrared rays and heat toward the upper shell and causing losses, and preventing the upper shell from heating up. The cover protects the insulating base, strengthens the structural strength of the insulating base, and reduces the occurrence of the insulating base breaking. By setting the temperature measurement avoidance hole, the temperature measurement component can be installed in the temperature measurement avoidance hole, thereby facilitating the temperature measurement of the temperature measurement component.

[0014] In one of the embodiments, the metal heating element is an annular tube, and the vertical projection of the heating wire on the plane where the metal heating element is located is located on the inner side of the metal heating element.

[0015] In this way, it can be ensured that the metal heating element will not block the far infrared rays emitted by the heating wire toward 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 insulating protrusion ring extending toward the light-transmitting plate, the first insulating protrusion ring is arranged around the temperature measurement avoidance hole, the heating wire is located on the outer peripheral side of the first insulating protrusion ring, and the first insulating protrusion ring is supported 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 radiating to the temperature measuring component, thereby preventing the heating wire from affecting the accuracy of temperature measurement of the temperature measuring component.

[0018] In one of the embodiments, the insulating and heat-insulating base is also provided with a second insulating protrusion ring extending toward the light-transmitting plate, the second insulating protrusion ring is arranged close to the peripheral edge of the insulating and heat-insulating base, the heating wire is located on the inner peripheral side of the second insulating protrusion ring, and the second insulating protrusion ring is supported 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 radiating to the cavity, thereby reducing the far infrared ray and heat loss of the heating wire and avoiding excessive temperature in the cavity.

[0020] In one of the embodiments, the upper cover assembly further includes a first elastic member, which is abutted between the upper shell and the far-infrared heating disk so that the first heat insulation convex ring and the second heat insulation convex ring are both abutted against the light-transmitting plate.

[0021] In this way, by providing the first elastic member, the first heat-insulating convex ring and the second heat-insulating convex ring can be pressed against the light-transmitting plate, thereby avoiding the gap between the first heat-insulating convex ring, the second heat-insulating convex ring and the light-transmitting plate due to tolerance, which may cause hot air leakage. At the same time, the first elastic member can play a buffering role to prevent the light-transmitting plate from being broken due to stress concentration during thermal expansion and contraction.

[0022] In one embodiment, a mounting portion is provided on the cover shell, the mounting portion is provided with a first mounting hole, the upper shell is provided with a mounting column, a fastener is connected and passed through the first mounting hole and fixedly connected to the mounting column, the fastener has an end stoppered on one side of the mounting portion, the first elastic member is sleeved on the outside of the mounting column, and the two ends of the first elastic member are respectively abutted against the upper shell and the mounting portion, so that the mounting portion abuts against the end of the fastener.

[0023] In this way, the mounting column not only plays the role of mounting the far-infrared heating plate, but also plays the role of limiting the first elastic member. The structure is very compact and the installation is very convenient.

[0024] In one embodiment, the temperature measuring assembly includes a temperature measuring probe and a second elastic member, the temperature measuring probe is penetrated by the cover shell, 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 shell.

[0025] Thus, by providing the second elastic member, the temperature measuring probe can be pressed against the upper baking pan, thereby avoiding inaccurate temperature measurement caused by the temperature measuring probe not being able to contact the upper baking pan due to tolerance. At the same time, the second elastic member can play a buffering role to prevent the light-transmitting plate from being broken due to stress concentration during thermal expansion and contraction.

[0026] In one embodiment, a limit plate is provided on the outer wall of the temperature measuring probe, and the limit plate is located between the cover shell and the light-transmitting plate. The second elastic member is sleeved on the outside of the temperature measuring probe, and its two ends are respectively abutted against the cover shell and the limit plate.

[0027] In this way, the limit plate can limit the movable travel of the temperature probe, so as to prevent the temperature probe from extending too long from the light-transmitting plate when the upper baking tray is removed, thereby affecting cooking. At the same time, the limit plate can limit the installation of the temperature probe, preventing the temperature probe from falling from the far-infrared heating plate.

[0040] See also Figures 1 to 3The present application provides a grilling machine, comprising a base assembly 200 and an upper cover assembly 100, wherein the upper cover assembly 100 is rotatably connected to the base assembly 200, and 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 comprises an upper shell 110 and an upper baking tray 120, wherein the upper baking tray 120 is detachably connected to the upper shell 110. The base assembly 200 comprises a lower shell 210 and a lower baking tray 220, wherein the lower baking tray 220 is mounted 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, a cooking cavity 201 is enclosed 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 covered on the base assembly 200 , a cooking cavity 201 is enclosed between the lower baking tray 220 and the upper shell 110 .

[0041] The upper shell 110 is provided with a metal heating element 130 and a far-infrared heating plate 140, and the metal heating element 130 is arranged around the far-infrared heating plate 140. When the upper grilling plate 120 is connected to the upper shell 110, the grilling machine can realize a grilling mode; when the upper grilling plate 120 is removed from the upper shell 110, the grilling machine can realize a baking mode. Thus, the grilling machine provided by the present application has a grilling mode and a baking mode by arranging a metal heating element 130 and a far-infrared heating plate 140 on the upper cover assembly 100, and the upper baking plate 120 is arranged to be detachably connected to the upper shell 110, and 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 plate 120, and grilling is achieved through the upper baking plate 120; in the baking mode, the far-infrared heating plate 140 or the metal heating element 130 can be turned on alone, and the food can be heated 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 at the same time, and the food can be heated by far-infrared radiation and thermal radiation at the same time, so that the cooking function of the grilling machine is more diverse. Moreover, the far-infrared radiation emitted by the far-infrared heating plate 140 is more uniform than that emitted by the far-infrared heating tube, so that the food can be heated more uniformly. At the same time, since the metal heating element 130 is disposed around the far-infrared heating disk 140 , the metal heating element 130 will not block the far-infrared rays radiated from the far-infrared heating disk 140 to the cooking cavity 201 .

[0042] Furthermore, the upper cover assembly 100 also includes a reflector 150 connected to the upper shell 110, the upper shell 110 and the reflector 150 surround a cavity 111, the far-infrared heating plate 140 is installed in the cavity 111, the metal heating element 130 is installed on the side of the reflector 150 away from the cavity 111, and the reflector 150 is provided with a light-transmitting window 151 for far-infrared rays to pass through corresponding to the far-infrared heating plate 140. 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 are surrounded in the cavity 111, providing an installation space for the far-infrared heating plate 140 and other electronic components, and the reflector 150 can reflect the heat emitted by the metal heating element 130 toward the upper shell 110 to the upper baking tray 120, thereby avoiding the loss of this part of the heat, and avoiding the heat dissipation to the upper shell 110 to cause the electronic components in the cavity 111 to be damaged by heat. By providing the light-transmitting window 151 on the reflector 150 , it is prevented that the reflector 150 blocks the far infrared rays emitted from the far infrared heating plate 140 to the cooking cavity 201 .

[0043] Furthermore, the reflector 150 may be a pure aluminum plate, an aluminum-plated plate or a galvanized plate, which has a good reflective effect.

[0044] Furthermore, the light-transmitting window 151 is set as a through hole, and the upper cover assembly 100 also includes a light-transmitting plate 160 arranged on the light-transmitting window 151, and the light-transmitting plate 160 is used to shield the far-infrared heating plate 140. In this way, by setting the light-transmitting plate 160, it is possible to prevent food residues or grease splashed 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 without affecting the radiation of far-infrared rays from the light-transmitting window 151. Of course, in other embodiments, the reflector may also partially transmit light to form a light-transmitting window.

[0045] Further, the light-transmitting plate 160 is a glass plate, and 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 a 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 disk 140.

[0046] Furthermore, the upper cover assembly 100 further includes a temperature measuring assembly 170, which is disposed 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. Thus, 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, thereby being able to accurately detect the temperature in the cooking cavity 201.

[0047] For further information, see Figures 3 to 5 The far-infrared heating plate 140 includes a cover 141, an insulating and heat-insulating base 142, and a heating wire 143. The insulating and heat-insulating base 142 is installed in the cover 141. A temperature measurement avoidance hole 1423 is provided in the center of the insulating and heat-insulating base 142. The temperature measuring assembly 170 is installed in the temperature measurement avoidance hole 1423. The heating wire 143 is arranged on the side of the insulating and heat-insulating base 142 facing the light-transmitting plate 160, and is arranged around the temperature measurement avoidance hole 1423. In this way, the far-infrared rays and heat generated by the heating wire 143 are radiated toward the light-transmitting plate 160, and then radiated to the food in the cooking cavity 201. The insulating and heat-insulating base 142 plays the role of installing the heating wire 143 and insulating and heat-insulating, so as to prevent the heating wire 143 from emitting far-infrared rays and heat toward the upper shell 110 and causing losses, and to prevent the upper shell 110 from heating up. The cover 141 protects the insulating base 142 and strengthens the structural strength of the insulating base 142, thereby reducing the possibility of the insulating base 142 being broken. By providing the temperature measurement avoidance hole 1423, the temperature measurement component 170 can be installed in the temperature measurement avoidance hole 1423, thereby facilitating the temperature measurement of the temperature measurement component 170.

[0048] In this embodiment, the temperature measurement avoidance hole 1423 is arranged at the center of the insulating and heat-insulating base 142, so that the temperature measuring component 170 installed in the temperature measurement avoidance hole 1423 detects 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 measurement avoidance hole 1423 is set as a circular hole, but it is not limited to this. The temperature measurement avoidance hole 1423 can also be a square or other shapes.

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

[0050] In this embodiment, the heating wire 143 is coiled in a serpentine shape around the temperature measurement avoidance hole 1423 to form multiple circles, so as to be evenly distributed on the surface of the insulating and heat-insulating base 142, so that the far infrared rays emitted toward the cooking cavity 201 are more evenly distributed, so that the food can be evenly heated.

[0051] See also Figures 1 to 3 Furthermore, the metal heating element 130 is an annular tube, and the vertical projection of the heating wire 143 on the plane where the metal heating element 130 is located is located inside the metal heating element 130. In this way, it can be ensured that the metal heating element 130 will not block the far infrared rays emitted by the heating wire 143 toward the cooking cavity 201, and the structure is very compact. In this embodiment, the far-infrared heating plate 140 is circular and the metal heating element 130 is square ring-shaped, but it is not limited to this. In other embodiments, the far-infrared heating plate can also be square and the metal heating element can also be circular ring-shaped.

[0052] See also Figures 3 to 5 Furthermore, the insulating and heat-insulating base 142 is provided with a first heat-insulating convex ring 1421 extending toward 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 is abutted 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 to the temperature-measuring component 170, thereby preventing the heating wire 143 from affecting the accuracy of the temperature measurement of the temperature-measuring component 170. In this embodiment, the first heat-insulating convex ring 1421 is a circular convex ring, which is arranged concentrically with the temperature-measuring avoidance hole 1423. However, it is not limited to this, and the first heat-insulating convex ring can also be a square convex ring or a convex ring of other shapes.

[0053] Furthermore, the insulating and heat-insulating base 142 is further provided with a second heat-insulating convex ring 1422 extending toward the light-transmitting plate 160, the second heat-insulating convex ring 1422 is arranged close to 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 is held 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 to the cavity 111, thereby reducing the far infrared rays and heat losses of the heating wire 143, and preventing the temperature in the cavity 111 from being too high.

[0054] In this embodiment, the heating wire 143 is located on the outer peripheral side of the first heat insulation protrusion ring 1421 and on the inner peripheral side of the second heat insulation protrusion ring 1422, and the first heat insulation protrusion ring 1421 and the second heat insulation protrusion ring 1422 are both abutted against the light-transmitting plate 160. Therefore, a side surface of the insulating and heat-insulating base 142 facing the light-transmitting plate 160, the first heat insulation protrusion ring 1421, the second heat insulation protrusion ring 1422 and the light-transmitting plate 160 enclose a closed cavity, and the heating wire 143 is arranged in the cavity. Due to the blocking effect of the insulating and heat-insulating base 142 on far-infrared light and heat, the far-infrared light and heat emitted by the heating wire 143 are radiated to the cooking cavity 201 through the light-transmitting plate 160, thereby reducing heat loss and increasing heating efficiency.

[0055] For further information, see Figures 2 to 5The upper cover assembly 100 further includes a first elastic member 180, which is held between the upper shell 110 and the far-infrared heating plate 140, so that the first heat-insulating convex ring 1421 and the second heat-insulating convex ring 1422 are both held against the light-transmitting plate 160. In this way, by providing the first elastic member 180, the first heat-insulating convex ring 1421 and the second heat-insulating convex ring 1422 can be pressed against the light-transmitting plate 160, thereby avoiding the gap between the first heat-insulating convex ring 1421, the second heat-insulating convex ring 1422 and the light-transmitting plate 160 due to tolerance, resulting in hot air leakage. At the same time, the first elastic member 180 can play a buffering role to prevent the light-transmitting plate 160 from being broken due to stress concentration during thermal expansion and contraction.

[0056] For further information, see 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 column 112, the fastener 190 is connected and penetrated through the first mounting hole 1412 and is fixedly connected to the mounting column 112, and the fastener 190 has an end stoppered on one side of the mounting portion 1411. The first elastic member 180 is sleeved on the outer side of the mounting column 112, and the two ends of the first elastic member 180 are respectively abutted against the upper shell 110 and the mounting portion 1411, so that the mounting portion 1411 is abutted against the end of the fastener 190. In this way, the mounting column 112 not only plays the role of installing the far-infrared heating plate 140, but also plays a role of limiting the first elastic member 180, and the structure is very compact and the installation is very convenient. As shown in the figure, in this embodiment, the cover 141 is provided with three mounting portions 1411, which are arranged in a triangle, and the mounting posts 112 are arranged corresponding to the mounting portions 1411, so that the far-infrared heating plate 140 is firmly installed. However, the invention is not limited thereto, and the number of mounting portions 1411 may also be two, four, five or six, and so on.

[0057] In this embodiment, the first elastic member 180 is a compression spring, which has a simple structure, good elasticity, and is easy to install. The fastener 190 is a screw, and a second mounting hole is provided in the mounting column 112, and the second mounting hole is provided with an internal thread. The screw passes through the first mounting hole 1412 and is threadedly connected with the second mounting hole, so that the far-infrared heating plate 140 can be installed on the upper shell 110.

[0058] like 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 is arranged through the cover 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 shell 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 tolerance. At the same time, the second elastic member 172 can play a buffering role to prevent the light-transmitting plate 160 from being broken due to stress concentration during thermal expansion and contraction.

[0059] It can be understood that one end of the temperature probe 171 connected to the wire is passed through the cover 141 , so that the wire can be installed in the cavity 111 .

[0060] In this embodiment, the end surface of the temperature measuring probe 171 facing the upper baking tray 120 is a plane, so that the contact between the temperature measuring probe 171 and the upper baking tray 120 is more reliable, so that the temperature measurement is more accurate.

[0061] Furthermore, a limit plate 173 is provided on the outer wall of the temperature probe 171, and the limit plate 173 is located between the cover 141 and the light-transmitting plate 160. The second elastic member 172 is sleeved on the outer side of the temperature probe 171, and the two ends are respectively abutted against the cover 141 and the limit plate 173. In this way, the limit plate 173 can limit the movable travel of the temperature probe 171, so as to avoid that when the upper baking tray 120 is removed, the length of the part of the temperature probe 171 extending out of the light-transmitting plate 160 is too long and affects the cooking. At the same time, the limit plate 173 limits the installation of the temperature probe 171, so as to prevent the temperature probe 171 from falling off the far-infrared heating plate 140.

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

[0063] like Figure 1 As shown, the lower grilling tray 220 of the base assembly 200 can be set as a deep tray. It can be understood that the deep tray is a grilling tray with a deeper depth relative to a conventional size grilling tray, and has a larger capacity. The deep tray can be used not only for grilling food, but also for boiling food. In addition, since the grilling machine includes the metal heating element 130 and the far-infrared heating tray 140, when the far-infrared heating tray 140 is turned on, its baking function is similar to the baking function of an oven, that is, the grilling machine is provided with the above-mentioned far-infrared heating tray 140, and an oven function is added relative to the grilling machine that heats food only through the upper grilling tray 120.

[0064] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, 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, they should be considered to be within the scope of this specification.

[0065] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
