Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cooking equipment, and in particular to a lighting structure and cooking equipment. Background Technology
[0002] To enhance the user's cooking experience, the top or side wall of the inner pot of cooking equipment is usually equipped with a lighting structure to provide light so that users can observe the cooking process or take food out of the inner pot.
[0003] Currently, some cooking appliances choose to install the lighting structure on the top mounting plate and guide the light to the side of the inner pot through vertical light guide columns. However, on the one hand, this installation method cannot be used if there is interference from the mounting plate, and on the other hand, the light guide columns are relatively long and costly.
[0004] If the lighting structure is installed directly on the side of the inner pot, although the length of the light guide column is reduced, the limited installation space between the inner pot and the side panel means that a large amount of heat generated by the inner pot during cooking will be conducted to the chip of the lighting structure, causing the LED of the light source to work at high temperature for a long time, which may lead to light decay or even damage. Utility Model Content
[0005] Therefore, it is necessary to address the problem that the LEDs are easily damaged due to excessive heat when the lighting structure is directly installed on the side of the inner pot. A lighting structure and cooking device that can be set on the side of the inner pot and effectively reduce the LED temperature is needed.
[0006] This application first provides a lighting structure disposed on the outer wall of the inner liner, including a mounting shell and a lighting component.
[0007] The mounting housing includes a fixed housing, multiple connecting columns, and a lamp housing. The fixed housing is fixed to the outer wall of the inner liner, and both ends of each connecting column are fixed to the fixed housing and the lamp housing, respectively.
[0008] The lighting assembly includes a lamp panel, a light guide column, and a viewing window. The lamp panel is fixed inside the lamp housing. The viewing window is fixed between the fixed housing and the inner liner and closes the lighting opening of the inner liner. The light guide column is fixed relative to the lamp panel, with one end passing through the through hole of the lamp housing and facing the lamp beads on the lamp panel, and the other end passing through the fixed housing and facing the viewing window.
[0009] In one embodiment, each of the connecting posts is arranged at equal intervals along the circumference with the light guide post as the center.
[0010] In one embodiment, each of the connecting posts is a hollow post.
[0011] In one embodiment, at least a portion of the outer wall of the connecting column is fixed with reinforcing ribs extending in its own axial direction.
[0012] In one embodiment, the width of the reinforcing rib along the radial direction of the connecting column gradually decreases towards the inner liner.
[0013] In one embodiment, an annular sealing element is fitted onto the outer peripheral surface of the viewing window glass, with part of the sealing element clamped between the fixed shell and the viewing window glass, and part of the sealing element clamped between the viewing window glass and the inner liner.
[0014] A second aspect of this application provides a cooking device, including an inner pot, an outer casing, and the aforementioned lighting structure, wherein the inner pot is disposed inside the outer casing, and the lighting structure is disposed between the inner pot and the outer casing.
[0015] In one embodiment, the lamp housing opens away from the inner liner, and the open end of the lamp housing is fitted against the inner wall of the outer casing.
[0016] In one embodiment, a flange is fixed to the outer peripheral surface of the opening end of the lamp housing, and the flange is fitted to the inner wall of the outer casing.
[0017] In one embodiment, a heat sink is fixed to the side of the lamp panel away from the inner liner, and a heat dissipation port corresponding to the heat sink is provided through the outer casing.
[0018] The aforementioned lighting structure connects the lamp housing and the fixed housing via connecting columns. On the one hand, it integrates the lamp housing and the fixed housing, avoiding direct contact between the lamp housing or lamp panel and the inner liner. This reduces solid-state heat transfer and effectively lowers the overall volume and installation difficulty of the lighting structure. On the other hand, the columnar structure of the connecting columns has a relatively small cross-section while meeting the connection and fixing requirements of the lamp housing, thereby further reducing solid-state heat transfer from the fixed housing to the lamp housing and preventing the lamp panel from overheating.

[0030] Please combine Figure 1 , Figure 2 as well as Figure 3 As shown, this application first provides a lighting structure disposed on the outer wall of the inner liner 100, including a mounting shell 10 and a lighting assembly. The mounting shell 10 includes a fixing shell 11, multiple connecting columns 12 and a lamp housing 13. The fixing shell 11 is fixed to the outer wall of the inner liner 100, and the two ends of each connecting column 12 are respectively fixed to the fixing shell 11 and the lamp housing 13. The lighting assembly includes a lamp panel 20, a light guide column 30 and a viewing window 40. The lamp panel 20 is fixed inside the lamp housing 13, and the viewing window 40 is fixed between the fixing shell 11 and the inner liner 100 and closes the lighting opening 110 of the inner liner 100. The light guide column 30 is fixed relative to the lamp panel 20, with one end passing through the through hole 131 of the lamp housing 13 and facing the lamp bead 21 on the lamp panel 20, and the other end passing through the fixing shell 11 and facing the viewing window 40.
[0031] In this application, the lamp housing 13 and the fixed housing 11 are connected by the connecting column 12. On the one hand, the lamp housing 13 and the fixed housing 11 are structurally integrated to avoid direct contact between the lamp housing 13 or the lamp panel 20 and the inner tube 100. This reduces solid heat transfer and effectively reduces the overall volume and installation difficulty of the lighting structure. On the other hand, the columnar structure of the connecting column 12 has a relatively small cross-section while meeting the connection and fixing requirements of the lamp housing 13, thereby further reducing solid heat transfer from the fixed housing 11 to the lamp housing 13 and preventing the lamp panel 20 from overheating.
[0032] Specifically, an annular light guide post mounting base is fixed on the lamp panel 20, the lamp bead 21 is located in the center of the light guide post mounting base, the light guide post mounting base extends through the through hole 131 to the outside of the lamp housing 13, and the light guide post 30 is fixed to the light guide post mounting base and is directly opposite the lamp bead 21.
[0033] More specifically, the inner circumferential diameter of the light guide post mounting base increases in the direction close to the inner liner 100, so as to guide the light emitted by the lamp bead 21 into the light guide post 30.
[0034] Please refer to Figure 2 As shown, in some embodiments, each connecting post 12 is arranged at equal intervals along the circumference with the light guide post 30 as the center; this arrangement can minimize the area of the connecting cross section while ensuring stable connection, thereby reducing the heat transfer of solid.
[0035] Preferably, four connecting posts 12 are fixedly connected between the fixed housing 11 and the lamp housing 13.
[0036] Of course, in other embodiments, the connecting columns 12 may be arranged in other ways or in other quantities, as long as they can meet the connection and support requirements of the lamp housing 13 and have a relatively small cross-sectional area. This application will not give examples of each of them here.
[0037] Please combine Figure 3 as well as Figure 4 As shown, in some embodiments, each connecting column 12 is a hollow column; compared with a solid column with the same cross-sectional area, the hollow column has stronger structural strength, and can reduce the cross-sectional area of the connecting column 12 as much as possible while meeting the connection support requirements, so as to reduce solid heat transfer and avoid overheating of the lamp panel 20.
[0038] Please refer to Figure 2 As shown, in some embodiments, at least part of the outer wall of the connecting column 12 is fixed with a reinforcing rib 121 extending in its own axial direction to increase the connection strength.
[0039] Preferably, the outer wall of the connecting column 12 is fixed with multiple reinforcing ribs 121 at equal intervals along its circumferential direction.
[0040] More preferably, four reinforcing ribs 121 are fixed at equal intervals along the circumferential direction on the outer wall of the connecting column 12.
[0041] In some embodiments, four connecting posts 12 are fixedly connected between the fixed housing 11 and the lamp housing 13, and reinforcing ribs 121 are fixed on two opposite connecting posts 12.
[0042] Please refer to Figure 2As shown, in some embodiments, the width of the reinforcing rib 121 along the radial direction of the connecting column 12 gradually decreases towards the inner liner 100; this arrangement enhances the structural strength of the connecting column 12 while minimizing the heat transferred to the inner liner 100 of the lamp housing 13 through the reinforcing rib 121, thereby preventing the lamp plate 20 inside the lamp housing 13 from overheating.
[0043] Please combine Figure 3 as well as Figure 4 As shown, in some embodiments, an annular sealing member 41 is fitted on the outer peripheral surface of the viewing window glass 40. Part of the sealing member 41 is clamped between the fixed shell 11 and the viewing window glass 40, and part of the sealing member 41 is clamped between the viewing window glass 40 and the inner liner 100 to prevent heat leakage inside the inner liner 100.
[0044] Please refer to Figure 1 As shown, the second aspect of this application provides a cooking device, including an inner pot 100, an outer casing 200, and the aforementioned lighting structure. The inner pot 100 is disposed inside the outer casing 200, and the lighting structure is disposed between the inner pot 100 and the outer casing 200.
[0045] Preferably, the lighting structure is located between the side of the inner liner 100 and the side panel of the outer casing 200. Compared with other locations, there are relatively few other structures on the side of the inner liner 100, which can effectively avoid interference and the lighting angle is more suitable.
[0046] Please combine Figure 2 , Figure 3 as well as Figure 4 As shown, in some embodiments, the lamp housing 13 opens away from the inner liner 100, and the open end of the lamp housing 13 is fitted to the inner wall of the side panel (not shown) of the outer casing 200.
[0047] By attaching the lamp housing 13 to the side panel of the outer casing 200, on the one hand, the side panel of the outer casing 200 can provide a certain auxiliary support effect to increase the installation reliability of the lighting structure of this application; on the other hand, it can form an independent space inside the lamp housing 13 to protect the lamp panel 20.
[0048] Please combine Figure 2 as well as Figure 3 As shown, in some embodiments, a flange 132 is fixed on the outer peripheral surface of the opening end of the lamp housing 13. The flange 132 fits against the inner wall of the outer casing 200. The flange 132 can increase the contact area between the lamp housing 13 and the side plate. On the one hand, it can better transfer the heat of the lamp housing 13 to the side plate for heat dissipation. On the other hand, it can also increase the stability of the mounting shell 10.
[0049] In some embodiments, a heat sink (not shown) is fixed on the side of the lamp panel 20 away from the inner liner 100, and a heat dissipation vent corresponding to the heat sink is provided through the side plate of the outer casing 200. The heat sink and the heat dissipation vent can better dissipate the heat accumulated on the lamp panel 20 to the outside, thereby preventing the lamp panel 20 from overheating.
[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.
[0051] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
