[0041] The present invention provides a grilling machine 100 .

[0042] In the embodiment of the present invention, referring to Figure 1 The grilling machine 100 includes a base assembly 10 and an upper cover assembly 30. The base assembly 10 includes a base body 11 and a baking tray 13. The baking tray 13 is rotatably arranged on the base body 11; the upper cover assembly 30 includes a cover body 31 and a multi-layer window structure 35. The cover body 31 is connected to the base body 11 and can be opened or covered on the baking tray 13. The multi-layer window structure 35 is provided on the cover body 31. The multi-layer window structure 35 and the cover body 31 enclose a light-transmitting and heat-insulating cavity 30a.

[0043] Reference Figure 6 as well as Figure 7 In this embodiment, the shape of the base assembly 10 and the upper cover assembly 30 can be roughly square, and the material of the cover 31 and the base 11 can be a plastic material with high structural strength and good heat dissipation. A cavity 11a is formed in the base 11, and the baking tray 13 is arranged in the cavity 11a, so that when the cover 31 covers the base 11, the baking tray 13 rotates in the cavity 11a and does not interfere with the cover 31. The cover 31 and the base 11 can be fixed by a hinge, so that the cover 31 can be flipped relative to the base 11 to cover or open the cavity 11a. An upper heating element can be provided in the cover 31, and a lower heating element can be provided in the base 11. The lower heating element is located at the bottom of the cavity 11a. Therefore, in the process of heating food, the upper heating element and the lower heating element can be used to heat both sides of the food at the same time to improve the heating efficiency. Refer to Figure 1 and Figure 2 The light-transmitting and heat-insulating cavities 30a can be provided in multiple numbers and arranged in sequence, thereby ensuring that the user can observe the cooking conditions inside the grilling machine 100 through the multi-layer window structure 35, and at the same time further reducing the temperature of the outer surface of the multi-layer window structure 35, thereby improving user safety.

[0044] The grilling machine 100 of the present invention comprises a base assembly 10 and a cover assembly 30. The base 11 of the base assembly 10 is connected to the cover 31 of the cover assembly 30, allowing the cover 31 to be opened or closed over a grilling pan 13, thereby enabling food to be placed or removed, cooked, and heated. The grilling pan 13 is rotatably mounted on the base 11, i.e., the grilling pan 13 can rotate relative to the cover 31 and the base 11. This allows the food in the grilling pan 13 to rotate relative to the heat source during heating, ensuring uniform heating and effectively preventing food from burning. Furthermore, the cover assembly 30 of the present invention is further provided with a multi-layered window structure 35 connected to the cover 31. When the grilling pan 13 rotates relative to the cover 31, the grilling pan 13 also rotates relative to the multi-layered window structure 35. This allows the user to view the cooking status and degree of the food from all directions through the multi-layered window structure 35, preventing the food from burning or overcooking. The multi-layer window structure 35 and the cover 31 enclose a light-transmitting and heat-insulating cavity 30a. This cavity 30a not only allows the user to observe the cooking process, but also prevents the transfer of heat and moisture, preventing the outer surface of the multi-layer window structure 35 from overheating. This prevents burns from the user touching the outer surface of the multi-layer window structure 35, thereby improving the convenience and safety of the grill 100.

[0045] In one embodiment of the present application, referring to Figure 1 The lid 31 has a connecting end 315 that is rotatably connected to the base 11, allowing the lid 31 to open and close relative to the baking tray 13. The multi-layered window structure 35 is located on the side of the lid 31 facing away from the connecting end 315. The connecting end 315 serves as a hinge axis, and the base 11 is provided with a rotating shaft hole. The hinge axis is inserted into the rotating shaft hole, allowing the lid 31 to rotate around the base assembly 10 about the axis of the hinge axis, allowing the lid 31 to flip relative to the base 11 and open or close to the base assembly 10. It is understood that the rotatable connection between the lid 31 and the base 11 can be achieved in a variety of ways, including a hinge connection, a hinge connection, and other methods. The multi-layered window structure 35 is located on the side of the lid 31 facing away from the first rotating member 317. When the user closes the lid 31, the multi-layered window structure 35 is closer to the user's body, making it easier for the user to observe through the multi-layered window structure 35.

[0046] Furthermore, with reference to Figure 2 and Figure 3The cover body 31 is provided with a first make way opening 31a and a second make way opening 31b which are connected to each other. The second make way opening 31b is located above the first make way opening 31a. The first make way opening 31a and the second make way opening 31b are at least partially arranged opposite to each other. The multi-layer window structure 35 includes a first window 351 and a second window 353. The first window 351 is embedded in the first make way opening 31a, and the second window 353 is embedded in the second make way opening 31b.

[0047] Specifically, the cover 31 is provided with a first opening 31a and a second opening 31b that communicate with each other, and the first window 351 and the second window 353 are adapted to fit within the first opening 31a and the second opening 31b, respectively. This facilitates the positioning and installation of the first and second windows 351, 353 of the multi-layer window structure 35, improving both initial installation efficiency and subsequent maintenance and disassembly efficiency. Furthermore, the second window 353 is located on the outer surface of the cover 31, allowing the user to observe the grilling process of food within the grill 100 through both the second window 353 and the first window 351. Furthermore, the light-transmitting and heat-insulating cavity 30a prevents the transfer of heat and moisture, thereby preventing the second window 353, located on the outer surface of the cover 31, from overheating, thereby ensuring user safety. Of course, the first window 351 and the second window 353 can also be fixed to the first clearance opening 31a and the second clearance opening 31b of the cover body 31 by means of a snap connection or screw connection, and the specific selection can be made by those skilled in the art. It should be noted that the multi-layer window structure 35 can also include an auxiliary window, which is located between the first window 351 and the second window 353 to separate the light-transmitting and heat-insulating cavity 30a into multiple insulation cavities, thereby further improving the effect of preventing the transfer of heat and moisture.

[0048] Furthermore, the cover 31 includes a first shell 311 and a second shell 313. The first shell 311 is connected to the second shell 313, and together they form a light-transmitting, heat-insulating cavity 30a having a second clearance opening 31b. The first clearance opening 31a is formed in the first shell 311 and is located on the bottom wall of the light-transmitting, heat-insulating cavity 30a. The second clearance opening 31b is located on the side wall of the light-transmitting, heat-insulating cavity 30a. Specifically, the first shell 311 and the second shell 313 can be detachably connected using a snap-fit ​​connection, such as a snap-fit ​​connection, to facilitate the subsequent maintenance and replacement of the internal components of the cover 31. The first shell 311 and the second shell 313 are combined to form a light-transmitting and heat-insulating cavity 30a, and the first clearance opening 31a is located on the bottom wall of the light-transmitting and heat-insulating cavity 30a, while the second clearance opening 31b is located on the side wall of the light-transmitting and heat-insulating cavity 30a. At the same time, the first window 351 and the second window 353 are respectively embedded in the first clearance opening 31a and the second clearance opening 31b, so that the user can observe the cooking status of the food on the baking tray 13 from the second window 353 on the side toward the first window 351 on the bottom. At the same time, the second window 353 is located on the side wall, so as to avoid the situation where the water vapor in the light-transmitting and heat-insulating cavity 30a moves upward and adheres to the second window 353 in large quantities, thereby achieving good anti-fog performance to ensure the visual effect of the multi-layer window structure 35. In addition, the second window 353 can be connected to the first shell 311 and the second shell 313 respectively by means of snaps or screws. In this embodiment, the specific installation process is: the bottom of the second window 353 can be snapped and positioned with the first shell 311 by means of snaps, and at the same time, a screw hole is set at the top of the second window 353, and the second window 353 is connected to the second shell 313 by passing the screw through the screw hole, so as to achieve the connection and fixation between the first shell 311, the second shell 313 and the second window 353, thereby ensuring the stability of the upper cover assembly 30 after assembly.

[0049] In one embodiment of the present application, referring to Figure 2 and Figure 3 The second window 353 is arranged to extend obliquely in the vertical direction; wherein, in order to further facilitate the user's observation and expand the user's field of view, the second window 353 is arranged to extend obliquely in the vertical direction, which not only increases the overlapping area of ​​the second window 353 and the first window 351, thereby expanding the user's field of view, but also makes the upper cover assembly 30 more beautiful as a whole. At the same time, the inclined second window 353 also makes it easier for the user to look down from above the cover body 31 to observe the cooking status of the food on the grilling tray 13 inside the grilling machine 100, thereby improving the user's convenience.

[0050] Optionally, refer to Figure 4The upper cover assembly 30 further includes an elastic sealing ring 36, which is sleeved around the periphery of the first window 351. Specifically, the elastic sealing ring 36 can be made of materials such as silicone or rubber. The elastic sealing ring 36 can be integrally formed with the first window 351 through injection molding, or the elastic sealing ring 36 can be elastically sleeved around the periphery of the first window 351. After the elastic sealing ring 36 is sleeved around the periphery of the first window 351, the outer wall of the elastic sealing ring 36 is interference-fitted with the inner wall of the first clearance opening 31a, thereby securing the first window 351 within the first clearance opening 31a. The elastic sealing ring 36 not only ensures the stability of the first window 351 but also seals the light-transmitting and heat-insulating cavity 30a, thereby further improving heat blocking and user safety.

[0051] In one embodiment of the present application, referring to Figure 3 A handle 3131 extends outward from one side edge of the second housing 313. Specifically, the handle 3131 may be formed by extending from the edge of the first housing 311. The handle 3131 facilitates opening and closing of the upper cover assembly 30. Furthermore, by positioning the handle 3131 away from the heating area 31B, the user is protected from being burned by the heat from the heating area 31B when operating the handle 3131, thereby improving the safety of the grill 100.

[0052] Optionally, the upper cover assembly 30 further includes a decorative panel 34, which is disposed on the top surface of the second housing 313. The decorative panel 34 can be attached to the top surface of the second housing 313 or removably secured to the top surface of the second housing 313 using a snap. The decorative panel 34 embellishes the appearance of the upper cover assembly 30, making it easier for users to identify it, enhancing the aesthetics of the product and boosting its market competitiveness.

[0053] In one embodiment of the present application, referring to Figures 1 to 3The upper cover assembly 30 further includes an upper heating element 33, which is disposed on the side of the cover 31 facing the grilling pan 13 and spaced apart from the multi-layer window structure 35 to provide a light wave heat source toward the grilling pan 13. The upper heating element 33 can be a heater such as a light wave tube or an electric heating tube. The upper heating element 33 can be an annular or quasi-annular structure, and the center of the upper heating element 33 coincides with the center of the cover 31 to ensure that the upper heating element 33 has a frying and grilling effect on the food. In this embodiment, the upper heating element 33 disposed on the cover 31 is configured as a light wave tube. It can be understood that the light wave heat source provided by the light wave tube can quickly generate high temperature and heat, and has a faster cooling speed, higher heating efficiency, and will not burn the food, thereby ensuring the color and taste of the food. At the same time, the upper heating element 33 is spaced apart from the multi-layer window structure 35, that is, a visible area 31A and a heating area 31B can be set side by side on the cover body 31, and the upper heating element 33 and the multi-layer window structure 35 are respectively arranged relative to the heating area 31B and the visible area 31A, so that the structural arrangement between the upper heating element 33 and the multi-layer window structure 35 is compact and reasonable, thereby effectively reducing the difficulty of assembling and disassembling the upper heating element 33 and the multi-layer window structure 35 separately, and effectively avoiding the situation where the volume of the upper cover assembly 30 is too large due to unreasonable arrangement. At the same time, the partitioned arrangement of the visible area 31A and the heating area 31B can effectively avoid the heating element from blocking the visible area 31A of the multi-layer window structure 35.

[0054] Further, refer to Figures 3 to 5 The upper cover assembly 30 includes a heat-insulating reflective structure 37 connected to the cover 31. The upper heating element 33 is located on the side of the heat-insulating reflective structure 37 facing the grilling pan 13. When the heat from the heating element attempts to dissipate outward, the heat-insulating reflective structure 37 blocks the heat and reflects it back toward the grilling pan 13. This not only prevents heat loss, ensuring proper cooking of food, but also prevents the surface temperature of the cover 31 from becoming too high, potentially causing burns to the user, thereby improving the safety of the grilling machine 100.

[0055] Furthermore, the heat-insulating reflective structure 37 includes a reflective cover 371 and a heat-insulating cover 373. The reflective cover 371 is connected to the cover 31, the upper heating element 33 is disposed within the reflective cover 371, and the heat-insulating cover 373 is connected to the side of the reflective cover 371 facing away from the upper heating element 33. The periphery of the reflective cover 371 is connected to the inner wall of the cover 31, while the heat-insulating cover 373 is connected to the outer wall of the reflective cover 371. The reflective cover 371 reflects the heat from the heating element, directing the heat dissipated outward toward the baking tray 13. The heat-insulating cover 373 blocks the heat dissipated outward, preventing it from being transferred to the cover 31 and causing it to heat up. Therefore, when heat attempts to dissipate outward, it is blocked by the reflective cover 371 and the heat-insulating cover 373, providing dual protection to ensure that the cover 31 does not generate high temperatures.

[0056] Furthermore, the reflector 371 includes a main body shell 3711 and a mounting boss 3713. The main body shell 3711 is connected to the cover 31, and the mounting boss 3713 is connected to the side of the main body shell 3711 facing away from the baking tray 13. The mounting boss 3713 defines a retaining cavity with a mounting opening facing the baking tray 13, and the heater is disposed within the retaining cavity. The heat shield 373 is disposed on the side of the mounting boss 3713 facing away from the main body shell 3711. Specifically, the main body shell 3711 and the mounting boss 3713 can be integrally formed to ensure the overall structural strength of the reflector 371. The heater can be installed within the retaining cavity of the mounting boss 3713 by passing through the mounting opening, thereby improving the accuracy of the heater installation. At the same time, since the heating element is limited in the limiting cavity, not only the stability of the installation of the heating element is guaranteed, but also most of the heat of the heating element is radiated along the installation opening toward the grilling pan 13, thereby improving the heating efficiency of the heating element. The heat insulation cover 373 is provided on the side of the installation boss 3713 away from the main body shell 3711, so that even when some heat passes through the reflective cover 371, it will be blocked by the heat insulation cover 373 to avoid the surface temperature of the cover body 31 from being too high, thereby improving the safety of the grilling machine 100.

[0057] Furthermore, the main body shell 3711 defines a viewing window 371a, which is positioned adjacent to the mounting boss 3713. Specifically, the viewing window 371a in the main body shell 3711 allows the user to observe the cooking process of the food on the grilling tray 13 in real time through the viewing window 371a, ensuring that the food does not burn. The multi-layered window structure 35 and the cover body 31 enclose a light-transmitting and heat-insulating cavity 30a, which blocks the viewing window 371a. Thus, when the upper cover assembly 30 is closed, the user can not only observe the cooking process of the food through the light-transmitting and heat-insulating cavity 30a, but the light-transmitting and heat-insulating cavity 30a also prevents the transfer of heat and moisture, preventing the outer surface of the multi-layered window structure 35 from overheating. This prevents the user from touching the outer surface of the multi-layered window structure 35 and getting burned, thereby improving the convenience and safety of the grilling machine 100.

[0058] Optionally, the circumferential edge of the main body shell 3711 extends outward to form a flange 3715, which is connected to the cover body 31. The flange 3715 extends outward from the circumferential edge of the main body shell 3711, so that when the main body shell 3711 and the mounting boss 3713 are inserted into the cover body 31 for installation, the flange 3715 abuts the lower surface of the cover body 31, thereby performing a positioning function, thereby ensuring the accuracy and efficiency of the installation of the reflector 371. It can also increase the contact area between the reflector 371 and the cover body 31, thereby improving the stability of the reflector 371 after installation. Furthermore, the flange 3715 can be connected to the lower surface of the cover body 31 by means of a snap or screw to further improve the stability of the installation of the reflector 371.

[0059] In one embodiment of the present application, a thermal insulation gap is provided between the heat shield 373 and the reflective cover 371. To further enhance the heat-blocking effect, a gap is formed between the reflective cover 371 and the heat shield 373. This prevents heat that passes through the reflective cover 371 from being directly transferred to the heat shield 373. Instead, the heat is buffered in the gap between the reflective cover 371 and the heat shield 373, further enhancing the heat-blocking effect.

[0060] In one embodiment of the present application, referring to Figure 5The heat-insulating reflective structure 37 also includes a clamping member 375 that clamps the heating element and is connected to the reflector 371 to secure the heating element within the reflector 371. Specifically, the clamping member 375 clamps and secures the heating element, which is then connected to the reflector 371 via snaps or screws. This not only ensures the stability of the heating element's installation, but also improves the stability of the heating during grilling in the grilling machine 100, ensuring uniform heating of food. This assembly method also facilitates operator operation, improving the efficiency of heating element installation and removal. It should be noted that multiple clamping members 375 are provided, spaced apart along the extension direction of the heating element, to secure the heating element from multiple directions, balance the forces acting on the heating element, and further ensure the stability of the installed heating element. The specific number of clamping members 375 can be selected by those skilled in the art and will not be elaborated here. In addition, the heat-insulating reflective structure 37 further includes a connector 377 and a fixing member 379. The connector 377 sequentially passes through the clamp 375, the reflector 371, and the heat-insulating cover 373, and is connected to the fixing member 379 to secure the clamp 375 to the reflector 371 and the heat-insulating cover 373. The connector 377 can be a stud, and the fixing member 379 can be a nut corresponding to the stud. The clamp 375, the reflector 371, and the heat-insulating cover 373 are each provided with corresponding threaded holes. Thus, the stud and nut are used to secure the clamp 375, the reflector 371, and the heat-insulating cover 373. This securing method is relatively simple to install, accurately positions, and is easy to disassemble, facilitating subsequent maintenance. Of course, in other embodiments, the clamp 375, the reflector 371, and the heat-insulating cover 373 can also be secured using commonly used connection methods in the art, such as pin connections and rivet connections. It should be noted that a plurality of the connecting members 377 and the fixing members 379 may be provided corresponding to the clamping members 375 to further improve the stability among the clamping members 375 , the reflective cover 371 and the heat insulating cover 373 after installation.

[0061] In one embodiment of the present application, referring to Figure 2 As with Figure 5, the upper cover assembly 30 also includes a protective cover 39, which is connected to the inner wall of the reflective cover 371 and encloses the installation cavity 30c. The heating element is located within the installation cavity 30c. Specifically, the protective cover 39 can be a microporous plate structure having multiple micropores to allow heat to pass through. The protective cover 39 can be removably fixed to the inner wall of the reflective cover 371 by means of a snap connection or buckle connection. Therefore, the provision of the protective cover 39 allows the heat of the heating element to be properly transferred within the installation cavity 30c while preventing users from accidentally touching the heating element.

[0062] The above content mainly introduces the relevant content of the structure of the upper cover assembly 30, and the following will specifically introduce the relevant embodiments of the relative rotation of the baking tray 13.

[0063] Reference Figures 6 to 8 In order to achieve the rotation of the baking tray 13, in one embodiment of the present application, the base assembly 10 includes a rotating member 15, which is arranged in the base body 11. A positioning member 131 is provided on the side of the baking tray 13 facing the base body 11. When the rotating member 15 is driven, it can abut and drive the positioning member 131 to rotate the baking tray 13 relative to the base body 11.

[0064] In this embodiment, the rotating member 15 includes a connecting post 151 and an abutment block 153. One end of the connecting post 151 is connected to the output end of the driver 17, and the other end is connected to the abutment block 153. The abutment block 153 is arranged at an angle to the connecting post 151 and abuts against the positioning member 131. The positioning member 131 is located on the side of the baking tray 13 facing the bottom wall of the cavity 11a and is integrally formed with the bottom wall of the baking tray 13 to ensure good structural strength between the positioning member 131 and the baking tray 13. The driver 17 and the rotating member 15 are disposed at the bottom of the cavity 11a. The connecting post 151 is connected to the driver 17 and extends toward the baking tray 13. Therefore, when the driver 17 drives the connecting post 151 to rotate, the connecting post 151 drives the abutment block 153 to abut against the positioning member 131, thereby rotating the baking tray 13 disposed within the cavity 11a. It can be understood that in this embodiment, the transmission is only achieved through the abutment between the positioning member 131 and the rotating member 15, so there is no need to set a more complex structure on the baking tray 13, which is beneficial to simplify the structure of the baking tray 13 and ensure the strength of the baking tray 13 itself.

[0065] Furthermore, in the direction in which the baking tray 13 rotates relative to the base 11 , a gap is provided between the rotating member 15 and the positioning member 131 , and the rotating member 15 can rotate within the gap.

[0066] Specifically, a gap is formed between the abutment block 153 of the rotating member 15 and the positioning member 131. The size of this gap can be adaptively set according to actual conditions. By providing a gap between the rotating member 15 and the positioning member 131, when the grilling pan 13 is loaded with a large amount of heavy food, the gap between the rotating member 15 and the grilling pan 13 provides a buffer for the driver 17 to move during startup. This allows the driver 17 to abut and drive the grilling pan 13 loaded with large food only after startup and normal operation. This reduces the possibility of the driver 17 encountering significant resistance during startup due to the large amount of food on the grilling pan 13, causing it to become stuck and overheat, leading to damage. This ensures the normal and stable operation of the cooking appliance.

[0067] Furthermore, in one embodiment of the present application, the base assembly 10 also includes a plurality of rolling members 19 , which are arranged at intervals along the circumference of the base body 11 , and the baking tray 13 abuts against the plurality of rolling members 19 and can be driven to rotate by the rotating member 15 .

[0068] The rolling element 19 may be a roller or a ball bearing, etc., and multiple rolling elements 19 may be embedded and fixed on the surface of the base 11 where the cavity 11a is formed. The number of rolling elements 19 may be three, four, or more. The provision of the rolling elements 19 allows the baking tray 13 to rotate when driven by the rotating element 15, resulting in rolling friction between the baking tray 13 and the base 11. This reduces the friction experienced by the baking tray 13 when rotating relative to the base 11, thereby improving the smoothness of the baking tray 13's rotation and reducing wear during rotation, thereby extending the service life of the baking tray 13 and the supporting structure. Furthermore, the provision of the rolling elements 19 can greatly reduce the noise caused by the friction between the baking tray 13 and the base 11.

[0069] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
