[0036] Refer to Figure 1 and Figure 2 , Figure 1 shows a schematic structural diagram of a cooking device 100 in an embodiment of this application, Figure 2 shows an exploded schematic diagram of a cooking device 100 in an embodiment of this application. The cooking device 100 provided in an embodiment of this application can be, for example, as Figure 1 and Figure 2The shown steam oven can also be other devices with cooking functions.

[0037] As Figure 2 shown, the cooking device 100 includes an inner container 110, a mounting plate 120, and a furnace lamp assembly 130. Among them, the inner container 110 includes a main body 111, and a cooking cavity 1111 is provided inside the main body 111. The cooking cavity 1111 is used to place and cook food materials. As Figure 1 and Figure 2 shown, the cooking device 100 further includes a door body 150 covering the main body 111. When the door body 150 covers the main body 111, it seals the opening of the cooking cavity 1111 to prevent the high-temperature water vapor inside the cooking cavity 1111 from overflowing.

[0038] Combined with Figure 4 and Figure 5 , a light inlet hole 1112 communicating the cooking cavity 1111 with the outside is formed in the main body 111. The inner container 110 further includes a light guide plate 112 covering the light inlet hole 1112. The light guide plate 112 is made of a light guide material, so that light beams can pass through the light guide plate 112 and enter the inside of the cooking cavity 1111, and the light guide plate 112 prevents the high-temperature water vapor inside the cooking cavity 1111 from overflowing through the light inlet hole 1112. In this embodiment, the light guide plate 112 is LOW-E tempered glass. In other embodiments, the light guide plate 112 can also be made of other high-temperature-resistant light guide materials.

[0039] As Figures 2 to 4 shown, the mounting plate 120 is located above the inner container 110. Two spaces isolated by the mounting plate 120 are formed above and below the mounting plate 120, so that the upper part of the mounting plate 120 is less affected by the high cooking temperature of the inner container 110. Preferably, the cooking device 100 further includes a heat insulation member wrapped around the outer periphery of the inner container 110. The heat insulation member can be heat insulation cotton to further prevent the ambient temperature of the components above the mounting plate 120 from rising due to the high cooking temperature of the inner container 110.

[0040] As Figures 2 to 5As shown, the furnace lamp assembly 130 includes a lighting lamp 131 and a light guide kit 132 for defining the propagation path of the light beam. The lighting lamp 131 is installed on the end face of the mounting plate 120 facing away from the inner container 110, so that the lighting lamp 131 is away from the high-temperature environment of the cooking cavity 1111. The environment it is in is blocked by the mounting plate 120 and is less affected by the temperature of the cooking cavity 1111, thereby reducing the requirement for the heat resistance of the lamp. Furthermore, a white light lamp such as an LED lamp can be selected to solve the visual color difference caused by the yellow light. The lighting lamp 131 is used to emit a light beam, and the emitted light beam is directed towards the light guide kit 132. The light guide kit 132 is used to propagate the light beam emitted by the lighting lamp 131 to the light guide plate 112, so that the light beam exits from the light inlet hole 1112 after being propagated by the light guide kit 132, enabling the light beam emitted by the lighting lamp 131 to enter the cooking cavity 1111 through the light inlet hole 1112, realizing the function of illuminating the inside of the cooking cavity 1111.

[0041] As Figure 4 and Figure 5 shown, in one embodiment, the lighting lamp 131 includes a power supply board 1311, a driving board 1312, and a light-emitting component 1313. The driving board 1312 and the light-emitting component 1313 are both electrically connected to the power supply board 1311 in an energizable manner. The light-emitting component 1313 is controlled by the driving board 1312. The power supply board 1311 is used to supply power to the driving board 1312 and the light-emitting component 1313. After the power supply board 1311 supplies power to the driving board 1312 and the light-emitting component 1313, the driving board 1312 controls the light-emitting component 1313 to turn on and off.

[0042] The driving board 1312 is easily interfered by microwaves, and when the driving board 1312 is interfered by microwaves, the light-emitting body will flicker. As Figure 4 and Figure 5 shown, in one embodiment, the lighting lamp 131 further includes a shielding box 1314. A shielding space 13141 is provided inside the shielding box 1314, and the driving board 1312 is located inside the shielding space 13141 to shield microwave interference through the shielding box 1314. In this embodiment, the shielding box 1314 is made of a metal material.

[0043] As Figure 6As shown, in one embodiment, the shielding box 1314 includes a bottom box 13142 and an upper cover 13143. The upper cover 13143 is rotatably connected to the bottom box 13142. The bottom box 13142 is provided with a placement space 13145 having a top opening and a side opening, and the placement space 13145 is used to place the driving board 1312. The upper cover 13143 includes a top cover 13146 and a side cover 13147 arranged at an angle. The upper cover 13143 covers the bottom box 13142 to jointly enclose a shielding space 13141. When the upper cover 13143 covers the bottom box 13142, the top cover 13146 and the side cover 13147 respectively cover the top opening and the side opening, so that the bottom box 13142 and the upper cover 13143 shield the driving board 1312 as much as possible, so that the driving board 1312 is not affected by microwave interference as much as possible. In this embodiment, the shielding box 1314 has a cuboid structure, but this is not a limitation. In other embodiments, the shielding box 1314 can also have a cylindrical, polygonal prism structure, etc.

[0044] As Figure 4 and Figure 5 shown, in one embodiment, the lighting lamp 131 further includes a connecting bracket 1315. The connecting bracket 1315 is installed on the end face of the mounting plate 120 facing away from the inner tank 110, and as Figure 7 and Figure 8 shown, the connecting bracket 1315 includes a first connecting portion 13151 connected to the power supply board 1311 and a second connecting portion 13152 connected to the driving board 1312. Among them, both the power supply board 1311 and the driving board 1312 are connected to the end face of the connecting bracket 1315 facing away from the mounting plate 120. As Figure 7 shown, the shielding box 1314 covers the second connecting portion 13152 and the driving board 1312 to obtain a better shielding effect.

[0045] As Figure 8 shown, in one embodiment, the second connecting portion 13152 protrudes with positioning posts 13153, and the bottom box 13142 is provided with positioning holes 13148 adapted to the positioning posts 13153. When the shielding box 1314 covers the second connecting portion 13152, at least part of the positioning posts 13153 is inserted into the positioning holes 13148 to limit the installation of the shielding box 1314 through the positioning posts 13153. As Figure 8 shown, in this embodiment, the number of the positioning posts 13153 is 2, and the 2 positioning posts 13153 are arranged at intervals to improve the positioning effect on the shielding box 1314. As Figure 8 shown, the shielding box 1314 is further provided with fastening holes for tightly connecting the second connecting portion 13152. The lighting lamp 131 further includes a fastener (not shown) connected to the fastening holes to fasten the shielding box 1314 and the second connecting portion 13152.

[0046] AsFigure 7 As shown, in one embodiment, the side cover 13147 is provided with a latch hole 13149, and the end surface of the connecting bracket 1315 facing the side cover 13147 is protruded with a latch 13154 aligned with the latch hole 13149, and the latch 13154 is configured to be able to be at least partially inserted into the latch hole 13149, so that when the upper cover 13143 is covered on the bottom box 13142, the upper cover 13143 is kept covered on the bottom box 13142 through the connection between the latch hole 13149 and the latch 13154, so that the driving plate 1312 is completely wrapped by the shielding box 1314 to improve the shielding effect, and at the same time, the connection method of the latch 13154 and the latch hole 13149 facilitates the disassembly of the shielding box 1314.

[0047] like Figure 6 As shown, in one embodiment, the shielding box 1314 is an integrated structure, and the connection between the bottom box 13142 and the upper cover 13143 is partially hollowed out to form a bending line 13144, so that the bottom box 13142 and the upper cover 13143 are rotatably connected. In other embodiments, the shielding box 1314 can also be a split structure, and the upper cover 13143 and the bottom box 13142 are rotatably connected through a rotating shaft.

[0048] like Figures 3 to 5 As shown, in one embodiment, the illuminating lamp 131 further includes a heat sink 1316 located on the back side of the light emitting element 1313. The heat sink 1316 is used to dissipate the heat generated by the light emitting element 1313 when it is working, so as to reduce the temperature of the light emitting element 1313. In this embodiment, the heat sink 1316 is made of aluminum alloy. Figure 4 and Figure 5 As shown, the lighting lamp 131 also includes a lamp board 1318 and a heat dissipation bracket 1317, the heat dissipation bracket 1317 is connected to the mounting plate 120, and the lamp board 1318 is connected to the top of the heat dissipation bracket 1317, the light-emitting element 1313 is connected to the end surface of the lamp board 1318 facing the mounting plate 120, and the heat sink 1316 is connected to the end surface of the lamp board 1318 away from the mounting plate 120.

[0049] like Figure 4 and Figure 5As shown, in one embodiment, the light guide kit 132 includes a lamp shade 1321 and a light guide column 1322. The light guide column 1322 is used to define the propagation path of the light beam. The light guide column 1322 can be a light guide material part through which the light beam can propagate, or the light guide column 1322 can be a hollow columnar structure and the light column propagates within the hollow structure inside the light guide column 1322. The lamp shade 1321 is made of a light-tight material. A protection space 13211 is provided inside the lamp shade 1321. The lamp shade 1321 covers the main body 111 and the light guide plate 112 is located within the protection space 13211. The light guide column 1322 extends downward from the lighting lamp 131 and passes through the mounting plate 120 until at least a part of the light guide column 1322 is inserted into the protection space 13211, so that the light beam emitted by the light-emitting body is propagated to the protection space 13211 through the light guide column 1322, and then passes through the light guide plate 112 within the protection space 13211 and enters the cooking cavity 1111 through the light inlet hole 1112. Preferably, the lamp shade 1321 has the function of reflecting the light beam of the light guide column 1322 to the light guide plate 112 to further increase the illumination brightness. As Figure 5 shown, the part of the light guide column 1322 located within the protection space 13211 is on the side of the light guide plate 112 facing away from the cooking cavity 1111.

[0050] As Figure 4 and Figure 5 shown, in one embodiment, the inner container 110 further includes a sealing gasket 113 sleeved on the outer periphery of the light guide plate 112. The light guide plate 112 is connected to the end face of the main body 111 facing away from the cooking cavity 1111, and at least a part of the sealing gasket 113 is squeezed between the main body 111 and the light guide plate 112. In this embodiment, the sealing gasket 113 is sleeved on the circumferential surface of the light guide plate 112. One end of the sealing gasket 113 extends along the end face of the light guide plate 112 facing the main body 111 and is squeezed between the main body 111 and the light guide plate 112, and the other end extends along the end face of the light guide plate 112 facing away from the main body 111 and is squeezed between the light guide plate 112 and the light guide kit 132. This can not only prevent light leakage and water vapor leakage from the gap between the main body 111 and the light guide plate 112, but also protect the light guide plate 112 through the sealing gasket 113 to prevent it from being broken due to excessive force.

[0051] As Figure 4 and Figure 5 shown, in one embodiment, the light guide kit 132 further includes a fixing plate 1323. The fixing plate 1323 is connected to the inner container 110 and partially covers the end faces of the sealing gasket 113 and the light guide plate 112 away from the main body 111 to fix the positions of the light guide plate 112 and the sealing gasket 113.

[0052] As Figure 4 and Figure 5As shown, in one embodiment, the number of light incident holes 1112 is multiple, and all the light incident holes 1112 are arranged in an array to form a light incident area, and the light guide plate 112 covers the light incident area.

[0053] As Figure 1 and Figure 2 As shown, in one embodiment, the cooking device 100 further includes a housing 140. The interior of the housing 140 is hollow, and the inner container 110, the mounting plate 120, and the oven lamp assembly 130 are all located inside the housing 140. The housing 140 is provided with heat dissipation holes 141 opposite to the illuminating lamp 131.

[0054] As Figure 1 and Figure 2 As shown, the end face of the housing 140 provided with the heat dissipation holes 141 is further provided with a main heat dissipation area 142 composed of a plurality of through holes for heat dissipation. The cooking device 100 further includes a heat dissipation fan 160 located opposite to the main heat dissipation area 142 and inside the housing 140. The heat dissipation fan 160 is used to inhale the cold air between the housing 140 and the cabinet to dissipate heat from the magnetron used for heating the cooking cavity 1111. The heat dissipation holes 141 and the main heat dissipation area 142 are located on the same end face, so that when the heat dissipation fan 160 works, the heat at the illuminating lamp 131 can be taken away together, thereby improving the heat dissipation effect at the illuminating lamp 131.

[0055] 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.

[0056] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can be made, and these all belong to the protection scope of the present application.
