[0048] The present invention provides an upper cover assembly 30, which is applied to a griddle 100. The griddle 100 includes a baking tray 13 for carrying food, and the upper cover assembly 30 is disposed above the baking tray 13 to heat and cook the food located at the baking tray 13.

[0049] Refer to Figures 1 to 3 , in an embodiment of the present invention, the upper cover assembly 30 includes a cover body 31, a quartz lamp tube 331, and a multi-layer window structure 35. The quartz lamp tube 331 is connected to the cover body 31; the multi-layer window structure 35 is disposed on the cover body 31, and a light-transmitting and heat-insulating cavity 30a is formed by enclosing between the multi-layer window structure 35 and the cover body 31.

[0050] Among them, the cover body 31 is used to carry the quartz lamp tube 331 and the multi-layer window structure 35. To ensure the stability and service life of the cover body 31, the cover body 31 can be made of metal materials, such as: stainless steel materials, aluminum materials, aluminum alloy materials, copper materials, copper alloy materials, iron materials, ferroalloy materials, etc. Of course, in order to reduce the mass of the cover body 31, the cover body 31 can also be made of plastic materials such as ABS, POM, PS, PMMA, PC, PET, etc., so as to facilitate the user to hold the upper cover assembly 30. The cover body 31 can be arranged in a regular shape such as a square or a circle, which can also facilitate the user to hold the upper cover assembly 30. The quartz lamp tube 331 can specifically be a halogen tube. A halogen tube is a sealed light-emitting and heat-generating tube filled with halogen elements, which can effectively ensure the service life of the heating wire. At the same time, it also has the advantages of stable electric heating power, fast heating, a high electric heat conversion rate of up to 70%, high thermal efficiency, non-oxidation during heating, a service life of more than 3000 hours, and safety and reliability, so as to improve the grilling effect of the griddle 100 on food. It should be noted that multiple light-transmitting and heat-insulating cavities 30a can be provided and arranged in sequence, so as to not only ensure that the user can observe the cooking situation inside the griddle 100 through the multi-layer window structure 35, but also further reduce the temperature of the outer surface of the multi-layer window structure 35 to improve the safety of user use.

[0051] The upper cover assembly 30 of the technical solution of the present invention can be installed on the griddle 100. The upper cover assembly 30 includes a cover body 31 and a light wave tube 331 connected to the cover body 31. Thus, the food can be heated and cooked through the light wave tube 331. Since the light wave heat source provided by the light wave tube 331 can quickly generate high temperature and high heat, and the cooling speed is also relatively fast, the heating efficiency is higher, so that the nutritional components of the food can be kept without loss to the maximum extent. At the same time, the upper cover assembly 30 further includes a multi-layer window structure 35 provided on the cover body 31. A light-transmitting and heat-insulating cavity 30a is formed by enclosing between the multi-layer window structure 35 and the cover body 31. Thus, after the upper cover assembly 30 is closed, the user can not only observe the grilling process of the food through the light-transmitting and heat-insulating cavity 30a, but also the light-transmitting and heat-insulating cavity 30a plays a role in blocking the transfer of heat and water vapor, so as to avoid the outer surface temperature of the multi-layer window structure 35 being too high, thereby preventing the user from touching the outer surface of the multi-layer window structure 35 and being scalded, and improving the convenience and safety of using the griddle 100.

[0052] In an embodiment of the present application, with reference to Figure 3, the cover body 31 is provided with a first relief opening 31a and a second relief opening 31b that are in communication with each other. The second relief opening 31b is located above the first relief opening 31a, and the first relief opening 31a and the second relief opening 31b are at least partially oppositely arranged; 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 relief opening 31a, and the second window 353 is embedded in the second relief opening 31b. Specifically, by providing a first relief opening 31a and a second relief opening 31b that are in communication with each other on the cover body 31, and the first window 351 and the second window 353 are respectively adapted to the first relief opening 31a and the second relief opening 31b, so that the first window 351 and the second window 353 can be directly embedded in the first relief opening 31a and the second relief opening 31b. Thus, it is convenient for the positioning and installation of the first window 351 and the second window 353 of the multi-layer window structure 35, improving the pre-installation efficiency and the later maintenance and disassembly efficiency of the first window 351 and the second window 353. At the same time, the cover body 31, the first window 351, and the second window 353 enclose a light-transmitting and heat-insulating cavity 30a. The second window 353 is located on the outer surface of the cover body 31. In this way, the user can sequentially observe the grilling process of the food inside the grilling machine 100 through the second window 353 and the first window 351, and the light-transmitting and heat-insulating cavity 30a also plays a role in blocking the transfer of heat and water vapor, thereby avoiding the excessive temperature of the second window 353 located on the outer surface of the cover body 31 and ensuring the safety of the user during use. Of course, the first window 351 and the second window 353 can also be fixed to the first relief opening 31a and the second relief opening 31b of the cover body 31 by means of snap connection or screw connection, etc., and can be specifically selected by those skilled in the art. It should be noted that the multi-layer window structure 35 can also include an auxiliary window, and the auxiliary window is located between the first window 351 and the second window 353 to divide the light-transmitting and heat-insulating cavity 30a into multiple heat-insulating cavities at intervals, so as to further improve the effect of blocking the transfer of heat and water vapor.

[0053] Furthermore, the cover body 31 has a top plate 311, a bottom plate 313 that are oppositely arranged, and a side plate 315 connecting the top plate 311 and the bottom plate 313. The first relief opening 31a is provided on the bottom plate 313, and the second relief opening 31b is provided on the top plate 311.

[0054] Specifically, the top plate 311, the bottom plate 313, and the side plates 315 can be assembled by means of snap connection or screw connection, etc., to facilitate the assembly of each part in the early stage and the maintenance and replacement in the later stage. The first relief opening 31a is formed in the bottom plate 313, and the second relief opening 31b is formed in the bottom plate 313, so that when the user observes through the multi-layer window structure 35, the user can directly look down from above the upper cover assembly 30, which is more convenient for the user to observe. At the same time, the second relief opening 31b is located at the top plate 311, so that the user is not likely to touch the second window 353, further ensuring the safety of the user during use. The present application places no restrictions on the shapes of the first relief opening 31a and the second relief opening 31b. For example, they can be circular, triangular, rectangular, square, or other shapes. The first window 351 and the second window 353 can be of corresponding shapes to facilitate direct embedding in the corresponding relief openings. Thus, with the first relief opening 31a and the second relief opening 31b in various shapes formed in the top plate 311 and the bottom plate 313 respectively, the user can not only observe the food heating situation through the first window 351 and the second window 353, but also make the upper plate assembly more beautiful. It should be noted that the second relief opening 31b can also be formed in the side plate 315, so that the cooking situation inside the griddle 100 can also be observed from the side. Specifically, it can be selected by those skilled in the art.

[0055] Furthermore, with reference to Figure 1 and Figure 3 , the second relief opening 31b is formed in the central region of the top plate 311. By forming the second relief opening 31b in the central region of the top plate 311, it is not only more convenient for the user to directly observe from the center above the cover body 31, but also the second relief opening 31b is located in the central region of the top plate 311, further preventing the user from easily touching the high-temperature second window 353 and improving the safety of the user during use. It can be understood that the cover body 31 is covered above the baking tray 13, and the central region of the top plate 311 corresponds to the central region of the baking tray 13. Thus, by forming the second relief opening 31b in the central region of the top plate 311, the user can more clearly and directly observe the food on the baking tray 13, improving the visual effect of the multi-layer window structure 35.

[0056] Optionally, the centers of the first relief opening 31a and the second relief opening 31b are coaxially arranged. To further increase the range of the user's field of view for observing food, the centers of the first relief opening 31a and the second relief opening 31b are coaxially arranged. In this way, not only is it more convenient and accurate to align the first window 351 and the second window 353 during installation, but also the overlapping part of the first window 351 and the second window 353 is ensured, further increasing the range of the user's field of view for observing food and improving the visual effect of the multi-layer window structure 35.

[0057] Optionally, the first viewing window 351 and the second viewing window 353 are arranged in parallel; wherein, the parallel arrangement of the first viewing window 351 and the second viewing window 353 reduces the refraction of light, has a relatively small impact on the visual effect of the multi-layer viewing window structure 35, and thus enables the user to observe more clearly from above the second viewing window 353.

[0058] Optionally, the surface of the second viewing window 353 facing away from the first viewing window 351 is coplanar with the upper surface of the top plate 311. Specifically, when the second viewing window 353 is installed in the second relief opening 31b, the surface of the second viewing window 353 facing away from the first viewing window 351 is coplanar with the upper surface of the top plate 311, which can not only avoid the situation that the second viewing window 353 protrudes from the outside and is easily damaged or scratches the user, etc., but also avoid the second viewing window 353 being embedded too deep in the second relief opening 31b, being not easy to disassemble and being more aesthetically pleasing.

[0059] In an embodiment of the present application, referring to Figure 3 , the upper cover assembly 30 further includes a reflector 371. The reflector 371 is connected to the bottom plate 313 and is located between the first relief opening 31a and the second relief opening 31b. The light wave tube 331 is disposed on the side of the reflector 371 facing the first relief opening 31a. Specifically, the reflector 371 can be detachably connected to the bottom plate 313 by means of snap connection or screw connection, etc. The light wave tube 331 is located on the side of the reflector 371 facing the first relief opening 31a. In this way, part of the light of the light wave tube 331 is directly radiated to the baking tray 13, and part is radiated to the inner surface of the reflector 371 and then reflected to the baking tray 13, so that the heat of the light wave tube 331 can be conducted to the food materials, avoiding heat loss, further improving the cooking effect of the light wave tube 331 on the food, and at the same time, since the heat is blocked by the reflector 371, it is possible to avoid the temperature of the top plate 311 rising too fast and scalding the user, thereby improving the safety of using the grilling machine 100.

[0060] Furthermore, in combination with Figure 3, the first window 351 includes a window plate 3511 and an extension plate 3513. The extension plate 3513 is connected to the periphery of the window plate 3511. At least part of the window plate 3511 is disposed opposite to the second window 353; the reflector 371 and the extension plate 3513 enclose a heating cavity 30b. The heating cavity 30b surrounds the light-transmitting and heat-insulating cavity 30a, and the light wave tube 331 is disposed in the heating cavity 30b. Specifically, the window plate 3511 and the extension plate 3513 can be integrally formed by injection molding to ensure the stability of the overall structure of the first window 351, or the extension plate 3513 can also be connected to the window plate 3511 in a detachable manner for easy later maintenance and replacement. The window plate 3511 is disposed opposite to the second window 353 so that users can directly observe the food through the second window 353 and the window plate 3511 in sequence, which is convenient for observation. The extension plate 3513 is disposed around the window plate 3511, so that it can enclose the heating cavity 30b with the reflector 371, and the heating cavity 30b is arranged to surround the light-transmitting and heat-insulating cavity 30a, so as to make the internal structure of the upper cover assembly 30 more compact and avoid the overall volume of the upper cover assembly 30 from being too large. By enclosing the extension plate 3513 and the reflector 371 to form a relatively closed heating cavity 30b, the light wave tube 331 is disposed in the heating cavity 30b to prevent the situation that users are easily burned by touching the light wave tube 331 when the upper cover assembly 30 is opened. Of course, it can be understood that the heat of the light wave tube 331 can pass through the extension plate 3513 and radiate to the baking tray 13 for cooking. In addition, the light wave tube 331 can be arranged in a ring shape, and the reflector 371 is arranged in an arc surface that is bent and protruded toward the top plate 311. In this way, the reflector 371 is disposed above the light wave tube 331 along the arc outer surface direction of the light wave tube 331, and a relatively uniform gap is maintained between the inner surface of the reflector 371 and the outer surface of the light wave tube 331, so that the light of the light wave tube 331 can be evenly reflected by the reflector 371 to the baking tray 13, further reducing the temperature rise of the top plate 311.

[0061] Furthermore, when projected along the direction from the second relief opening 31b to the first relief opening 31a, the projected area of the second window 353 is larger than the projected area of the window plate 3511. Specifically, in order to ensure the grilling effect of the light wave tube 331 on the food and enable users to clearly observe the food grilling process from the second window 353, when projected along the direction from the second relief opening 31b to the first relief opening 31a, the projected area of the second window 353 is larger than the projected area of the window plate 3511. Thus, a larger viewing range can be provided for users, enabling them to observe more clearly and ensuring the radiation area of the light wave tube 331 to guarantee the food grilling process by the light wave tube 331, so as to improve the usability of the grilling machine 100.

[0062] In an embodiment of the present application, the first window 351 and the second window 353 are transparent plastic plates or transparent glasses. Among them, the first window 351 and the second window 353 may themselves adopt a transparent material to form a light-transmitting area, or a part of the first window 351 and the second window 353 adopts a light-transmitting material to form a light-transmitting area, that is, the first window 351 and the second window 353 may themselves be made of transparent plastic or transparent glass, or a through hole may be opened in the middle of the first window 351 and the second window 353, and a transparent plastic plate or a transparent glass plate may be installed and connected to the through hole, so that it is not only convenient for users to observe, but also forms a heat insulation effect, improving the safety of using the griddle 100.

[0063] The present invention also provides a griddle 100. Referring to Figure 2 and Figure 3 , the griddle 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 arranged on the base body 11. The upper cover assembly 30 is connected to the base body 11 and can be opened or closed on the baking tray 13. The specific structure of the upper cover assembly 30 refers to the above embodiment. Since the griddle 100 of the present application adopts all the technical solutions of the above all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated one by one here.

[0064] Furthermore, referring to Figure 4 , the base body 11 of the base assembly 10 of the present application includes a base body 113 and a lower reflector 115115. A receiving cavity with an opening is formed in the base body. The baking tray is arranged at the opening. The lower reflector 115115 is arranged in the receiving cavity and at least partially located between the baking tray 33 and the bottom wall of the receiving cavity. The receiving setting can simplify the overall structural design of the base assembly.

[0065] Furthermore, the base assembly 10 further includes a lower heating element 15. The lower heating element 15 is arranged on the wall surface of the lower reflector 115 facing the baking tray. By setting the lower heating element 15 in this way, both the upper and lower sides of the baking tray can be cooked, so that the cooking efficiency can be improved. The lower heating element 15 can also adopt the way of light wave heating or the way of heating with a heating tube.

[0066] Referring to Figure 5 and Figure 6, in an embodiment of the present application, the griddle 100 further includes a buffer structure disposed at least at one of the base assembly 10 and the upper cover assembly 30, and is configured to provide a buffering force when the upper cover assembly 30 opens or closes the base assembly 10. Specifically, the buffer structure can be separately provided on the upper cover assembly 30 or the base assembly 10, or partially provided on the upper cover assembly 30 and the other part on the base assembly 10. It should be noted that the buffering force provided by the buffer structure can buffer the impact force when the two are closed, or buffer the impact force after opening to a preset angle when the upper cover assembly 30 and the base assembly 10 are opened. In this embodiment, the case where the buffer structure provides a buffering force when the upper cover assembly 30 and the base assembly 10 are closed will be taken as an example for description.

[0067] Therefore, for the griddle 100 of the technical solution of the present invention, by adding a buffer structure at least at one of the hinged upper cover assembly 30 and the base assembly 10, a buffering force can be provided during the opening or closing process of the upper cover assembly 30 and the base assembly 10 to buffer the impact force during opening or closing. Therefore, even when the upper cover assembly 30 is heavy, no strong impact will be caused during the state change process of opening or closing with the base assembly 10, effectively avoiding damage to the upper cover assembly 30 and the base assembly 10 during opening or closing, preventing damage to the light wave tube 310 due to excessive impact force during the closing process, and avoiding safety accidents such as pinching hands.

[0068] With reference to Figure 5 and Figure 6 , in an embodiment of the present application, the upper cover assembly 30 includes a cover body 31 and a hinge shaft 33 fixedly connected to the cover body 31. The light wave tube 310 is disposed inside the cover body 31. The damper 50 is sleeved outside the hinge shaft 33 and is connected to the base assembly 10 to enable the cover body 31 to flip relative to the base assembly 10 to open or close the base assembly 10.

[0069] Among them, the buffer structure includes a sleeve 51 and a shaft core 53 arranged inside the sleeve 51. An installation portion 511 extends from the outer wall of the sleeve 51, and is fixedly connected to the base assembly 10 through the installation portion 511. The hinge shaft 33 passes through the shaft core 53 inside the sleeve 51. A partition plate 55 is provided on the shaft core 53. The partition plate 55 divides the space inside the sleeve 51 into two parts, and the partition plate 55 is provided with a liquid passing hole 551 communicating the two parts of the space. Hydraulic oil is present in both parts of the space. Therefore, when the cover body 31 rotates relative to the base assembly 10, the hinge shaft 33 rotates together with the cover body 31. At this time, the hinge shaft 33 drives the shaft core 53 and the partition plate 55 on the shaft core 53 to rotate together. Thus, during the rotation of the partition plate 55, while squeezing the hydraulic oil, the hydraulic oil also acts as a counter-pushing force on the partition plate 55, thereby forming a buffering effect.

[0070] Furthermore, the buffer structure is a damper 50. In this embodiment, the damper 50 can be a hydraulic damper. Of course, in other embodiments, the damper 50 can also be a structure commonly used in the prior art such as an elastic damper. Using the damper 50 as the buffer structure can buffer the impact of the heavier upper cover assembly 30 and has strong reliability.

[0071] In an embodiment of the present application, the griddle 100 further includes a baffle 70. The baffle 70 is connected to the base assembly 10 and shields the hinged part between the base assembly 10 and the upper cover assembly 30. Among them, the baffle 70 can be detachably fixed to the seat body 11 of the base assembly 10 by means of screw connection, snap connection, etc., and forms a shield for the hinged part. Thus, through the design of the baffle 70, not only does the overall appearance of the griddle 100 become more beautiful, but also it can prevent users from accidentally touching the hinged part between the upper cover assembly 30 and the base assembly 10 and causing safety risks such as pinching hands.

[0072] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made using the description and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
