[0021] The present application will be further described in detail below with reference to the accompanying drawings.

[0022] This application discloses a steam oven inner cavity, referring to... Figure 1 and Figure 2The device includes a light source assembly 1, an inner liner body 2, a heat dissipation assembly 3, and a light guide assembly 4. The light source assembly 1 is located outside the inner liner body 2, and at least a portion of the light guide assembly 4 extends into the interior of the inner liner body 2. The light guide assembly 4 guides the light from the light source assembly 1 outside the inner liner body 2 into the interior of the inner liner body 2. Both the light source assembly 1 and the light guide assembly 4 are connected to the heat dissipation assembly 3, and a heat dissipation gap 5 is formed between the light source assembly 1 and the heat dissipation assembly 3. The heat dissipation gap 5 communicates with the outside of the inner liner body 2.

[0023] Reference Figure 2 The light source assembly 1 includes an LED light board 11, on which LED beads are disposed.

[0024] Reference Figure 2 and Figure 3 The heat dissipation component 3 includes a heat dissipation base 31 and four connecting posts 32 arranged circumferentially along the heat dissipation base 31. One or more connecting posts 32 can also be provided to support the LED light panel 11. The heat dissipation base 31 is generally cylindrical. The connecting posts 32 are located at one end of the heat dissipation base 31 away from the inner liner body 2. The connecting posts 32 are evenly arranged circumferentially along the heat dissipation base 31. The inner wall of the connecting posts 32 has threads.

[0025] A connector 6, which is threaded into the connecting post 32, passes through the LED light panel 11. The connector 6 is a screw, and the height of the screw is greater than the depth of the thread on the connecting post 32. After the connector 6 is connected, a heat dissipation gap 5 is formed between the LED light panel 11 and the end of the heat sink 31 facing away from the inner liner body 2, so that the inside of the heat sink 31 and the side of the LED light panel 11 facing the heat sink 31 can form air circulation with the outside.

[0026] In other embodiments, the heat dissipation gap 5 between the LED light board 11 and the heat sink 31 can be formed without the use of connector 6 and connecting post 32. For example, a portion of the LED light board 11 or the heat sink 31 can be designed to have a heat dissipation gap 5, and the two can be fixed together.

[0027] In other embodiments, the connector 6 can be a pin, rivet, stud, elastic block, pad, etc., as long as it can form a heat dissipation gap 5 between the light source assembly 1 and the heat dissipation assembly 3 after the light source assembly 1 and the heat dissipation assembly 3 are connected.

[0028] In other embodiments, the connecting post 32 can be disposed on the light source assembly 1, and the connector 6 can then connect the heat dissipation assembly 3 and the light source assembly 1.

[0029] In other embodiments, multiple LED light panels 11 may be arranged circumferentially around the heat sink 31.

[0030] The light guide assembly 4 includes a light guide post 41 and a base 42 connected together. At least a portion of the base 42 is located inside the inner body 2. The base 42 has a light guide space 420 extending through both ends. The light guide post 41 passes through the light guide space 420, with one end extending out of the base 42 away from the heat sink 31, and the other end extending towards the light source assembly 1. In other embodiments, a transparent lampshade can also be provided around the end of the base 42 away from the heat sink 31 to protect the light guide post 41.

[0031] The inner walls of the light guide space 420 of the light guide post 41 and the base 42 are fixed by adhesive. In other embodiments, the light guide post 41 and the base 42 can also be fixed by other connectors.

[0032] The light guide post 41 is made of high borosilicate material.

[0033] The base 42 has threads on the outside of the light guide space 420. The threaded part of the base 42 passes through the side wall of the inner body 2 and is detachably connected to the heat sink 31 through the threads.

[0034] In other embodiments, the base 42 is located inside the inner liner body 2, at least a portion of the heat dissipation base 31 is outside the inner liner body 2, and at least another portion extends into the inner liner body 2 and is connected to the base 42.

[0035] In other embodiments, the detachable connection between the base 42 and the heat sink 31 can also be secured by fasteners.

[0036] To better propagate light and dissipate heat, a mounting space 310 is provided near the center of the heat sink 31. The mounting space 310 extends through both ends of the heat sink 31. A light guide column 41 extends outward from inside the inner liner body 2 into the mounting space 310, approaching the location of the light source assembly 1. At least a portion of the light source assembly 1 is aligned with the mounting space 310, allowing the light from the light source assembly 1 to be guided into the interior of the inner liner body 2 via the light guide column 41. Simultaneously, the mounting space 310 communicates with the outside through a heat dissipation gap 5, allowing heat within the mounting space 310 to dissipate outward through the heat dissipation gap 5. The outer wall of the light guide column 41 can contact the inner wall of the mounting space 310, or a certain gap can be formed.

[0037] To further dissipate heat, the heat sink 31 is provided with multiple heat sinks 311. The multiple heat sinks 311 are arranged around the installation space 310 and located inside the heat sink 31. Adjacent heat sinks 311 form a heat dissipation space inside the heat sink 31. The heat dissipation space runs through both ends of the heat sink 31 and is connected to the heat dissipation gap 5, which expands the contact area with hot air and improves the heat dissipation effect through the airflow at the heat dissipation gap 5.

[0038] To improve installation reliability, a heat dissipation flange 312 is formed on one end face of the heat dissipation base 31 near the inner liner body 2, and a base flange 421 is provided on the base 42. A sealing gasket 7 is provided on the side of the heat dissipation flange 312 facing the outer wall of the inner liner body 2, and / or a sealing gasket 7 is provided on the side of the base flange 421 facing the inner wall of the inner liner body 2. When the base 42 and the heat dissipation base 31 are fixed, the base 42 and the heat dissipation base 31 can clamp the side wall of the inner liner body 2 from the inside and outside to achieve sealing and fixing.

[0039] In this embodiment, in order to improve the heat dissipation effect, the heat dissipation component 3 and the base 42 are made of ceramic material.

[0040] This application also discloses a steam oven, see embodiments thereof. Figure 4 The invention includes a housing 8 and a steam oven liner as described in the above technical solution. The housing 8 surrounds the steam oven liner, and a heat-conducting space is formed between the housing 8 and the liner body 2. At least a portion of the heat dissipation component 3 is located within the heat-conducting space, and the light source component 1 is located outside the housing 8. In some embodiments, the heat-conducting space is connected to the air box of the integrated stove or a fan is independently set to dissipate heat to the heat-conducting space, thereby forming airflow at the heat dissipation gap 5, increasing the contact area between the light source component 1 and the airflow, strengthening convection, and improving heat dissipation efficiency.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
