Technical Field

[0001] The utility model relates to the technical field of cooking equipment, in particular to an illumination structure and a multifunctional cooking equipment. Background Art

[0002] In order to improve the cooking experience of users, currently, a lighting device is usually installed at the top or side wall of the inner cavity of a cooking equipment to provide illumination for the user to observe the cooking situation or pick up and place food in the inner cavity.

[0003] However, according to the different internal structures of the cooking equipment (such as the number, volume, installation method, etc. of internal modules), there are different restrictions on the installation position of the lighting device.

[0004] In some cooking equipment, the distance between the light-emitting source of the lighting device and the window glass on the inner cavity is relatively far, resulting in a large lighting dead angle in the inner cavity and the situation of dark under the light, which affects the lighting effect. Summary of the Utility Model

[0005] Based on this, in view of the problem that in some current lighting structures, due to the relatively far distance between the light-emitting source and the window glass, there is dark under the light, it is necessary to provide an illumination structure and a multifunctional cooking equipment that can improve the lighting effect in such installation structures and avoid the problem of dark under the light.

[0006] This application first provides an illumination structure, including an inner cavity and an illumination component. A window hole is formed through one side of the inner cavity.

[0009] In one embodiment, the illumination component further includes a lamp board bracket fixed to the side plate and located between the side plate and the inner cavity. The lamp board is fixed to the side away from the inner cavity of the lamp board bracket. A lamp bead hole is formed through the lamp board bracket, and the lamp beads of the lamp board penetrate through the lamp bead hole to be aligned with the light guide column.

[0010] In one embodiment, a lamp board cavity is formed between the side plate and the lamp board bracket. The lamp board is located in the lamp board cavity. A plurality of heat dissipation holes are formed in the side plate, and a heat sink is fixed to the side away from the inner cavity of the lamp board.

[0011] In one embodiment, the lighting assembly further includes a light guide cylinder fixed to the inner container. A light guide hole is formed through the interior of the light guide cylinder. One end of the light guide hole corresponds to and is sealed with the window glass, and the other end corresponds to the lamp beads.

[0012] The light guide column is fixed to the light guide cylinder and is located inside the light guide hole. At least part of the lamp board bracket is located inside the light guide hole, so that the lamp beads are located inside the light guide hole.

[0013] In one embodiment, the cross-sectional aperture of the light guide cylinder decreases from the side of the side plate to the side of the inner container. A light-blocking wall for blocking the light guide hole is fixed to the inner wall of the light guide hole, and the light guide column penetrates and is fixed to the light-blocking wall.

[0014] In one embodiment, there is a gap between the lamp board bracket and the inner wall of the light guide hole in the circumferential direction.

[0015] In one embodiment, the lighting assembly further includes a sealing ring and an annular light guide cylinder bracket. One end of the light guide cylinder bracket is fixed to the inner container, and the other end is fixed to the light guide cylinder.

[0016] The window glass is located inside the light guide cylinder bracket and includes an embedding part and a sealing part. The embedding part is embedded in the window hole. The circumferential edge of the sealing part is sleeved with the sealing ring, and the sealing ring is in close contact and sealed with the inner container and the light guide cylinder bracket respectively along the axial direction of the light guide column.

[0017] In one embodiment, the power cord of the lamp board is plugged into the power board, and the power board is fixed relative to the inner container; a protective wire is detachably fixed on the lamp board, and the other end of the protective wire is fixed to the inner container, and the length of the protective wire is shorter than that of the power cord.

[0018] The second aspect of the present application provides a multifunctional cooking device, including the above lighting structure.

[0019] In the above lighting structure, a light guide column is arranged between the lamp beads and the window glass. After the light emitted by the lamp beads is guided by the light guide column, it is emitted from the other end of the light guide column and shines on the window glass. At this time, the other end of the light guide column can be regarded as the actual light-emitting source of the lighting structure of the present application. Therefore, on the premise that the positions of the lamp board and the window glass remain unchanged, the present application shortens the distance between the light-emitting source and the window glass through the light guide column, thereby reducing the lighting dead angle inside the inner container, effectively alleviating the situation of dark under the lamp, and improving the lighting effect.

[0031] Please refer to Figure 1 and Figure 2 As shown, the present application first provides an illumination structure, including an inner container 10 and an illumination assembly 30. A viewing window hole 11 is formed through one side of the inner container 10; the illumination assembly 30 includes a lamp board 31, a light guide column 32 and a viewing window glass 33, and the three are relatively fixed. Among them, the viewing window glass 33 is fixed to the inner container 10 to seal the viewing window hole 11, and the lamp beads 311 of the lamp board 31, the light guide column 32 and the viewing window glass 33 are arranged in sequence and face each other along the direction close to the inner container 10.

[0032] A light guide column 32 is provided between the lamp beads 311 and the window glass 33. After the light emitted by the lamp beads 311 is guided by the light guide column 32, it is emitted from the other end of the light guide column 32 and directed towards the window glass 33. At this time, the other end of the light guide column 32 can be regarded as the actual light source of the lighting structure of the present application. Therefore, on the premise that the positions of the lamp board 31 and the window glass 33 remain unchanged, the present application shortens the distance between the light source and the window glass 33 through the light guide column 32, thereby reducing the lighting dead angle inside the inner container 10, effectively alleviating the situation of dark under the lamp, and improving the lighting effect.

[0033] It should be noted that there are also some cooking devices at present. The installation space of the internal lighting device is limited. As a result, when the cooking device is working, a large amount of heat generated by the inner container will be transmitted to the chip of the lighting device. And the limited space will also lead to poor heat dissipation effect of the chip, which in turn causes the operating temperature of the chip to exceed the standard. Long-term use will accelerate the aging of the chip and affect the service life of the chip.

[0034] Regarding this, please refer to Figure 1 and Figure 2 As shown, in some embodiments, the lighting structure further includes a side plate 20. The inner container 10 is fixedly connected to the side plate and a gap is formed therebetween. The lamp board 31 is fixed to the side plate 20, the light guide column 32 is fixed to the inner container 10, and there is a gap between the light guide column 32 and the lamp beads 311.

[0035] By providing a gap between the light guide column 32 and the lamp beads 311, that is, the lighting assembly 30 is separately arranged. Among them, the lamp board 31 is arranged on the side plate 20, and the base part structures such as the window glass 33 are arranged on the inner container 10. The two parts do not directly contact, so that the heat generated by the inner container 10 during the cooking process cannot be directly and largely transmitted to the lamp board 31, thereby reducing the operating temperature of the lamp board 31 and improving its service life.

[0036] Please refer to Figure 1 and Figure 2 As shown, in some embodiments, the lighting assembly 30 further includes a lamp board bracket 34 fixed to the side plate 20 and located between the side plate 20 and the inner container 10. The lamp board 31 is fixed to the side away from the inner container 10 of the lamp board bracket 34. A lamp bead hole 341 is formed through the lamp board bracket 34, and the lamp beads 311 of the lamp board 31 pass through the lamp bead hole 341 to be directly opposite to the light guide column 32.

[0037] Since the lamp board bracket 34 is located between the lamp board 31 and the inner container 10, the lamp board bracket 34 can block and absorb part of the heat of the inner container 10, thereby preventing the temperature of the lamp board 31 from being too high. Also, since the lamp board bracket 34 is fixed to the side plate 20, the lamp board bracket 34 can quickly conduct the heat it absorbs to the side plate 20 through contact heat conduction, and dissipate the heat to the external environment through the side plate 20. That is, using the side plate 20 as a whole as a heat dissipation component increases the heat dissipation capacity of the lighting component 30 to reduce the operating temperature of the lamp board 31.

[0038] Of course, in some other embodiments, the lamp board bracket 34 can also be integrally formed with the side plate 20, and is formed by the side plate 20 being recessed toward the inner container 10 side.

[0039] In some embodiments, the projection of the lamp board 31 along the irradiation direction of the lamp beads 311 is located within the lamp board bracket 34 to increase the heat insulation and heat absorption capacity of the lamp board bracket 34, avoid the heat generated by the inner container 10 during cooking from directly radiating onto the lamp board 31, and further reduce the temperature of the lamp board 31 of the lighting structure of the present application during use.

[0040] Please refer to Figure 1 and Figure 2 As shown, in some embodiments, a lamp board cavity 35 is formed between the side plate 20 and the lamp board bracket 34. The lamp board 31 is located within the lamp board cavity 35. A plurality of heat dissipation holes 21 are provided on the side plate 20. A heat sink 36 is fixed to the side of the lamp board 31 away from the inner container 10. The design of the heat sink 36 and the heat dissipation holes 21 can further improve the heat dissipation capacity of the lamp board 31.

[0041] In some embodiments, the edge of the lamp board bracket 34 is hermetically fitted to the side plate 20 so that the lamp board cavity 35 communicates with the outside only through the heat dissipation holes 21, thereby minimizing the heat transfer to the gap space between the side plate 20 and the inner container 10 and preventing heat accumulation.

[0042] In some embodiments, the lamp board bracket 34 is fixed to the side of the side plate 20 close to the inner container 10.

[0043] Specifically, the lamp board bracket 34 and the side plate 20 are fixed by screws. Of course, in some other embodiments, the two can also be fixed by other common fixing methods, and the present application does not list them one by one here.

[0044] Please refer to Figure 1 and Figure 2 As shown, in some embodiments, the lighting component 30 further includes a light guide cylinder 37 fixed to the inner container 10. A light guide hole 371 is formed through the inside of the light guide cylinder 37. One end of the light guide hole 371 corresponds to and is sealed with the window glass 33, and the other end corresponds to the lamp beads 311;

[0045] The light guide column 32 is fixed to the light guide cylinder 37 and is located inside the light guide hole 371. The lamp board bracket 34 is at least partially located in the light guide hole 371 so that the lamp beads 311 are located in the light guide hole 371.

[0046] On the one hand, the light guide cylinder 37 can guide the light emitted by the lamp beads 311 to the window glass 33, improving the lighting effect of the lighting assembly 30. On the other hand, it can also prevent the situation that the lighting effect is affected due to foreign impurities (such as heat insulation cotton, etc.) entering the window glass 33 from the outside.

[0047] Preferably, the light guide cylinder 37 is made of high-temperature resistant plastic or other high-temperature resistant materials.

[0048] Please refer to Figure 1 and Figure 2 As shown, in some embodiments, the cross-sectional aperture of the light guide cylinder 37 decreases from the side plate 20 side to the inner liner 10 side. A light-blocking wall 372 that blocks the light guide hole 371 is fixed to the inner wall of the light guide hole 371. The light guide column 32 penetrates and is fixed to the light-blocking wall 372 to ensure that after the light emitted by the lamp beads 311 is reflected and guided by the inner wall of the light guide hole 371 and the light-blocking wall 372, most of the light can be emitted along the light guide column 32, thereby reducing the leakage between the light source and the window glass 33 on the premise of minimizing light loss as much as possible.

[0049] Please refer to Figure 1 and Figure 2 As shown, in some embodiments, there is a gap between the lamp board bracket 34 and the inner wall of the light guide hole 371 in the circumferential direction. With such a setting, a certain installation margin can be provided, so that every time of installation, even if there is a certain deviation in the relative position between the side plate 20 and the inner liner 10, the lamp board bracket 34 will not interfere with the light guide cylinder 37, thereby reducing the installation difficulty of the lighting structure of the present application.

[0050] Please refer to Figure 1 and Figure 2 As shown, in some embodiments, the lighting assembly 30 further includes a sealing ring 38 and an annular light guide cylinder bracket 39. One end of the light guide cylinder bracket 39 is fixed to the inner liner 10, and the other end is fixed to the light guide cylinder 37;

[0051] The window glass 33 is located inside the light guide cylinder bracket 39 and includes an embedded part 331 and a sealing part 332. The embedded part 331 is embedded in the window hole 11, and the circumferential edge of the sealing part 332 is sleeved with a sealing ring 38. The sealing ring 38 is tightly sealed with the inner liner 10 and the light guide cylinder bracket 39 respectively along the axis direction of the light guide column 32.

[0052] Specifically, the window glass 33 is in a stepped shape, and the cross-section of the sealing ring 38 is in a U shape.

[0053] In some embodiments, the window glass 33 is frosted glass, so that when the user observes outward from the inside of the inner container 10, the lamp board 31 cannot be directly observed, thereby improving the aesthetics of the lighting assembly 30.

[0054] Please refer to Figure 3 and Figure 4 As shown, in some embodiments, the power cord of the lamp board 31 is plugged into the power board, and the power board is fixed relative to the inner container 10; a protective wire 312 is detachably fixed on the lamp board 31, and the other end of the protective wire 312 is fixed to the inner container 10, and the length of the protective wire 312 is shorter than that of the power cord.

[0055] With such a setting, when the staff removes the side plate 20, even if the staff does not notice the power cord of the lamp board 31 on the side plate 20, the protective wire 312 will be tightened first during the removal process, thereby playing a prompting and protective role to avoid the situation of breaking or damaging the power cord.

[0056] Specifically, if it is necessary to completely remove the side plate 20, only need to remove the protective wire 312 from the lamp board 31 after the side plate 20 is opened, and then unplug the power cord of the lamp board 31.

[0057] The second aspect of the present application provides a multifunctional cooking device, including the above-mentioned lighting structure.

[0058] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0059] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
