[0030] With the rise of Internet of Things technology, digital cooking is becoming more and more popular among consumers. By adding a camera function to the steam oven, more practical functions can be added to the oven, such as ingredient recognition before cooking, doneness recognition during cooking, and video sharing of the cooking process after cooking.

[0031] However, when a steam oven with microwave function adds a camera function, microwave leakage may occur due to the hole opened in the cooking cavity to install the camera, thereby creating risks and hazards in use.

[0032] See also Figure 1 and Figure 2 The camera mechanism 10 of the embodiment of the utility model is used for a cooking appliance 100. The camera mechanism 10 includes a camera component 14 and a protective component 12. The protective component 12 is arranged on the light incident side of the camera component 14. The protective component 12 includes a bracket 16 and a microwave shielding component 18. The microwave shielding component 18 is arranged around the circumferential side of the bracket 16. The microwave shielding component 18 is configured to shield microwave leakage between the bracket 16 and the inner wall of the opening of the cavity 74 of the cooking cavity 72 of the cooking appliance 100.

[0033] The above-mentioned camera mechanism 10 and microwave shielding member 18 are arranged around the circumferential side of the bracket 16, which can shield the microwave leakage between the bracket 16 and the inner wall of the opening of the cavity 74 of the cooking cavity 72 of the cooking appliance 100, thereby ensuring the normal operation of the camera mechanism 10 and preventing microwave leakage, thereby ensuring the safe use of the cooking appliance 100.

[0034] Specifically, the cooking appliance 100 includes a cooking cavity 72 for cooking, and the camera mechanism 10 is installed on the cooking appliance 100. The cavity 74 of the cooking cavity 72 has an opening so that the camera mechanism 10 can capture the state of food in the cooking cavity 72.

[0035] The protection assembly 12 includes a bracket 16 and a microwave shielding member 18. The bracket 16 is mounted at the opening of the cavity 74 of the cooking cavity 72. The camera assembly 14 is located outside the cavity 74 of the cooking cavity 72 and mounted on the bracket 16. The microwave shielding member 18 is arranged around the circumferential side of the bracket 16 to shield microwave leakage between the bracket 16 and the inner wall of the opening of the cavity 74 of the cooking cavity 72 of the cooking appliance 100, thereby avoiding the use risks and hazards caused by microwave leakage.

[0036] The bracket 16 is installed at the opening of the cavity 74 of the cooking cavity 72 , and the microwave shielding member 18 is arranged around the circumferential side of the bracket 16 . The microwave shielding member 18 can be arranged on the inner side of the cavity 74 , or the microwave shielding member 18 can be arranged on the outer side of the cavity 74 .

[0037] When realizing the microwave shielding function, the microwave shielding member 18 and the bracket 16 are made of metal. The metal microwave shielding member 18 can effectively prevent the leakage of microwaves. The principle is that there are a large number of free electrons inside the metal. When microwaves encounter the metal surface, the free electrons will vibrate and absorb the energy of the microwaves, converting it into heat energy. At the same time, the metal will also reflect the microwaves, further reducing the penetration of microwaves. This reflection and absorption work together to ensure that the microwaves are mainly confined inside the cooking cavity 72 and will not leak to the outside, thereby ensuring human safety and the safety of the use of the cooking appliance 100.

[0038] See also Figure 1 In some embodiments, the bracket 16 includes a first bracket 20 and a second bracket 22, the camera assembly 14 is installed on the second bracket 22, the first bracket 20 fixes the second bracket 22 to the cavity 74 of the cooking cavity 72, and the microwave shielding member 18 is disposed between the second bracket 22 and the cavity 74 and is in direct contact with the outer wall of the cavity 74.

[0039] In this way, the microwave shielding member 18 is in direct contact with the outer wall of the cavity 74, which can ensure good conduction between the second bracket 22 and the cavity 74, so that the second bracket 22 and the cavity 74 can form an effective microwave shielding body to ensure that microwaves cannot leak out from the gap.

[0040] Specifically, the first bracket 20 is disposed on the inner wall of the cavity 74 of the cooking cavity 72, and the second bracket 22 is disposed on the outer wall of the cavity 74 of the cooking cavity 72. After the first bracket 20 and the second bracket 22 are fixedly connected, the bracket 16 can be fixedly connected to the cavity 74 of the cooking cavity 72. The camera assembly 14 is fixedly connected to the second bracket 22, and the camera assembly 14 can be fixedly installed on the cavity 74 of the cooking cavity 72.

[0041] The microwave shielding member 18 is disposed between the second bracket 22 and the cavity 74 and is in direct contact with the outer wall of the cavity 74. This ensures good conduction between the second bracket 22 and the cavity 74, so that the second bracket 22 and the cavity 74 can form an effective microwave shielding body, ensuring that microwaves cannot leak out from the gap of the cavity 74 opening.

[0042] Optionally, the microwave shielding member 18 may be disposed between the cavity 74 and the first bracket 20 and directly contact the inner wall of the cavity 74. In this way, it is also possible to ensure that microwaves cannot leak out from the gap of the cavity 74 opening.

[0043] In one embodiment, the microwave shielding member 18 is a copper mesh washer, which is disposed between the second bracket 22 and the cavity 74 and directly contacts the outer wall of the cavity 74. This ensures good conduction between the second bracket 22 and the cavity 74.

[0044] See also Figure 1 and Figure 3 In some embodiments, the protective component 12 includes a light-transmitting member 23, the camera component 14 includes a camera 28 and a camera bracket 30, the camera 28 is installed on the camera bracket 30, the camera bracket 30 is installed on the second bracket 22, the second bracket 22 has a first through hole 34, the first bracket 20 includes a first connecting tube 24, the second bracket 22 includes a receiving groove 26, the receiving groove 26 is sleeved on the first connecting tube 24, the light-transmitting member 23 is accommodated in the first connecting tube 24, and the camera 28 module is used to collect light through the first through hole 34 and the light-transmitting member 23.

[0045] In this way, the protective component 12 is fixed to the opening of the cavity 74 of the cooking cavity 72 of the cooking appliance 100, the camera component 14 is fixed to the second bracket 22, and the camera 28 photographs the interior of the cavity 74 of the cooking appliance 100 through the first through hole 34 and the light-transmitting member 23.

[0046] Specifically, in order to photograph the food inside the cooking cavity 72, a hole is opened in the cavity 74 of the cooking cavity 72, the protective component 12 blocks the opening, and the camera component 14 is installed on a side of the protective component 12 that is located outside the cooking cavity 72. Thus, the camera component 14 can photograph the interior of the cooking cavity 72 through the protective component 12. The protective component 12 blocks the opening to prevent microwaves from leaking out of the cooking cavity 72 and isolate the camera component 14 from the high temperature inside the cooking cavity 72.

[0047] The camera assembly 14 includes a camera 28 and a camera bracket 30. The camera 28 is mounted on the camera bracket 30. The camera bracket 30 is fixedly connected to the second bracket 22. The light-transmitting member 23 is accommodated in the first connecting tube 24 of the first bracket 20. The second bracket 22 is provided with a first through hole 34. The camera 28 can shoot the interior of the cooking cavity 72 through the first through hole 34 and the light-transmitting member 23.

[0048] See also Figure 4 In some embodiments, the aperture of the first through hole 34 ranges from (0, 16 mm).

[0049] In this way, microwaves can be prevented from leaking through the first through holes 34 .

[0050] Specifically, the aperture of the first through hole 34 has a value range of (0, 16 mm], which allows the camera 28 module to collect light through the first through hole 34 and the light-transmitting member 23, while preventing microwave leakage. The aperture of the first through hole 34 can be 5 mm, 7 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm or 16 mm, or any other value within the range of (0, 16 mm]. When the aperture of the first through hole 34 exceeds 16 mm, there may be a risk of microwave leakage.

[0051] It should be noted that the aperture of the first through hole 34 can be the same everywhere, that is, the first through hole 34 is a round hole. Alternatively, the first through hole 34 can have a plurality of different apertures, that is, the first through hole 34 is a square hole or a polygonal hole. In this case, the apertures of different sizes of the first through hole 34 need to be within the range (0,16mm] to avoid the risk of microwave leakage.

[0052] In one embodiment, the first through hole 34 is a square hole, and the diagonal length of the first through hole 34 is less than or equal to 16 mm. In this way, microwaves cannot leak out from the first through hole 34, and the shape of the square hole matches the shooting range of the camera 28 to avoid blocking the shooting line of sight.

[0053] See also Figure 1 and Figure 3 In some embodiments, the second bracket 22 includes a first mounting portion 36 and a second mounting portion 38, the first mounting portion 36 is connected to the second mounting portion 38, the first mounting portion 36 defines a receiving groove 26, the second mounting portion 38 is cylindrical, the camera bracket 30 defines a mounting hole 40, and the second mounting portion 38 is passed through the mounting hole 40 to fix the second mounting portion 38 to the camera bracket 30.

[0054] In this way, the second bracket 22 transfers heat to the camera bracket 30 only through the second mounting portion 38 , the transferred heat is small and the heat dissipation is fast, and the heat of the camera assembly 14 will not increase too much.

[0055] Specifically, the second bracket 22 includes a first mounting portion 36 and a second mounting portion 38, the first mounting portion 36 is connected to the second mounting portion 38, the first mounting portion 36 is fixedly connected to the first bracket 20, the second mounting portion 38 is fixedly connected to the camera bracket 30, the second mounting portion 38 is cylindrical, the camera bracket 30 has a mounting hole 40, and the second mounting portion 38 is inserted into the mounting hole 40 so that the second mounting portion 38 is fixedly connected to the camera bracket 30.

[0056] The second mounting portion 38 is cylindrical, disposed on the first mounting portion 36, extending toward the camera bracket 30, and passing through the mounting hole 40 of the camera bracket 30, and fixedly connected to the camera bracket 30. The second bracket 22 will heat up quickly due to contact with the cavity 74 of the cooking cavity 72, but the second bracket 22 and the camera bracket 30 are only in contact with the mounting hole 40 of the camera bracket 30 through the second mounting portion 38, so the temperature of the second bracket 22 is slowly transferred to the camera bracket 30, which can prevent the temperature of the camera bracket 30 from being too high.

[0057] See also Figure 4 and Figure 5In some embodiments, the second bracket 22 defines a second through hole 42 , and the number of the second through holes 42 is multiple, and the multiple second through holes 42 are arranged around the first through hole 34 , and the aperture of the second through hole 42 is smaller than or equal to the aperture of the first through hole 34 .

[0058] In this way, the heat transferred from the second bracket 22 to the camera bracket 30 can be reduced.

[0059] Specifically, the camera bracket 30 is fixedly connected to the second bracket 22, and a plurality of second through holes 42 are opened on the second bracket 22. Thus, the interior of the second through holes 42 can serve as an air insulation layer, which can effectively reduce the heat transfer from the second bracket 22 to the camera bracket 30 along the axial direction of the second through holes 42.

[0060] The second through holes 42 are evenly distributed on the second bracket 22 and are arranged around the first through holes 34, so as to ensure a uniform heat insulation effect.

[0061] The aperture of the second through hole 42 is smaller than the aperture of the first through hole 34 , which can prevent microwaves from leaking through the second through hole 42 .

[0062] See also Figure 1 and Figure 3 In some embodiments, the light-transmitting member 23 includes a first light-transmitting member 44, a second light-transmitting member 46 and a first sealing member 48. The first light-transmitting member 44 and the second light-transmitting member 46 are stacked along a first direction in the first connecting tube 24, and the first sealing member 48 is arranged between the first light-transmitting member 44 and the second light-transmitting member 46 so that there is a gap between the first light-transmitting member 44 and the second light-transmitting member 46.

[0063] In this way, the first light-transmitting member 44 and the second light-transmitting member 46 can reduce the temperature in the cooking cavity 72 from being transferred to the camera assembly 14 . Meanwhile, the light-transmitting member 23 does not affect the shooting of the camera assembly 14 .

[0064] Specifically, the first light-transmitting member 44 and the second light-transmitting member 46 are stacked and arranged in the first connecting tube 24 along the first direction, and the first light-transmitting member 44 and the second light-transmitting member 46 are separated by the first sealing member 48. In the first connecting tube 24, a sealed cavity 74 can be formed between the first light-transmitting member 44 and the second light-transmitting member 46 to achieve air heat insulation. Therefore, the protective component 12 can achieve a good heat insulation effect through the two layers of light-transmitting members 23 and the sealed cavity 74 therebetween.

[0065] Among them, the first direction is the up and down direction shown in the figure.

[0066] The materials of the first light-transmitting member 44 and the second light-transmitting member 46 include but are not limited to glass, acrylic plate, glass fiber reinforced plastic or other artificial light-transmitting materials.

[0067] In one embodiment, the first light-transmitting member 44 and the second light-transmitting member 46 are low-emissivity (Low-E) glass. The emissivity of the surface of Low-E glass is low, which can reduce heat transfer and achieve a better heat insulation effect.

[0068] See also Figure 1 and Figure 3 In some embodiments, the first connecting tube 24 has a fixing portion 52 on the outer periphery away from the second bracket 22. When the camera mechanism 10 is installed in the cavity 74 of the cooking cavity 72 of the cooking appliance 100, the first connecting tube 24 is passed through the opening of the cavity 74, the fixing portion 52 abuts against the inner wall of the cavity 74, and the fixing portion 52 opens a sealing groove 54. The first bracket 20 includes a second sealing member 55. When the camera mechanism 10 is installed in the cavity 74 of the cooking cavity 72 of the cooking appliance 100, the second sealing member 55 is accommodated between the sealing groove 54 and the inner wall surface of the cavity 74.

[0069] In this way, the protection component 12 can seal the opening of the cavity 74 to prevent the steam in the cooking cavity 72 from leaking.

[0070] Specifically, in the steam mode of the cooking appliance 100, the opening may cause steam leakage. When the camera mechanism 10 is installed in the cavity 74 of the cooking cavity 72 of the cooking appliance 100, the first bracket 20 contacts the inner wall surface of the cavity 74 of the cooking cavity 72, and the second bracket 22 contacts the outer wall surface of the cavity 74. The second sealing member 55 is respectively arranged between the contact surfaces of the first bracket and the cavity 74, so that the opening of the cavity 74 can be sealed when the first bracket 20 is fixedly connected to the cavity 74 of the cooking cavity 72, thereby preventing steam leakage in the cooking cavity 72.

[0071] Optionally, the second sealing member 55 is a high temperature resistant silicone sealing ring, thereby ensuring that the sealing member has a longer service life and avoiding sealing failure and steam leakage.

[0072] See also Figure 2 and Figure 3 In some embodiments, the camera bracket 30 includes a base 56 and a cover (not shown), the cover is covered on the base 56 to form a housing space for the camera 28, the base 56 has an air inlet 60 and an air outlet 62, the camera mechanism 10 also includes a fan 66 and a heat dissipation duct 68, the fan 66 and the heat dissipation duct 68 are installed on the outside of the cooking cavity 72, and the fan 66 and the air inlet 60 are connected through the heat dissipation duct 68.

[0073] In this way, the fan 66 supplies air to the camera assembly 14 to cool it down, so that the heat of the camera assembly 14 can be effectively dissipated.

[0074] Specifically, the camera bracket 30 has an air inlet 60 and an air outlet 62, and the air inlet 60 is connected to the fan 66 through the heat dissipation duct 68. The fan 66 can supply air into the heat dissipation duct 68, and the cold air flows in the camera bracket 30 through the air inlet 60 and the air outlet 62, which can cool the camera assembly 14, thereby preventing the temperature of the camera assembly 14 from being too high and affecting the service life of the camera assembly 14.

[0075] See also Figure 1 and Figure 3 In some embodiments, the camera mechanism 10 includes a heat shield 70 , the camera assembly 14 is mounted on the second bracket 22 , the second bracket 22 is fixedly connected to the camera bracket 30 , and the heat shield 70 is disposed between the second bracket 22 and the camera bracket 30 .

[0076] In this way, it is possible to prevent the heating element from causing the temperature of the camera assembly 14 to be too high when heating the protective assembly 12 .

[0077] Specifically, the camera bracket 30 and the second bracket 22 are fixedly connected, and the heating element is sleeved on the second bracket 22. When heating, the temperature is transferred from the second bracket 22 to the first bracket 20 and the light-transmitting element 23. The heat insulation board 70 is arranged between the second bracket 22 and the camera bracket 30, which can significantly reduce the temperature transfer of the heating element to the camera assembly 14 after the heating element is heated, thereby ensuring that the camera assembly 14 is in a relatively constant temperature and suitable for work.

[0078] In one embodiment, the heat insulation board 70 is a mica sheet, which has excellent heat insulation performance and can effectively isolate heat transfer, thereby maintaining a stable temperature inside the object. In addition, the mica sheet has good high temperature resistance and can be stably insulated for a long time in a high temperature environment without damage, and is suitable for a cooking appliance 100 with a high working temperature.

[0079] In summary, when the camera mechanism 10 of the embodiment of the utility model is installed on the cooking appliance 100, the protective component 12 can insulate the camera component 14 and prevent steam and microwave leakage. At the same time, the camera mechanism 10 can dissipate heat to ensure that the camera 28 operates within the allowable operating temperature range.

[0080] The heat insulation function is achieved through the following two ways: 1. The heat insulation is achieved by the first light-transmitting member 44 and the second light-transmitting member 46 and the air insulation layer therebetween, which can effectively prevent the heat in the cooking cavity from being transferred to the camera assembly 14; 2. The heat insulation plate 70 is provided between the second bracket 22 and the camera bracket 30, which can effectively prevent the heat of the bracket 16 from being transferred to the camera assembly 14; 3. A second mounting portion 38 in the shape of a long cylindrical cone is provided, which can increase the thermal resistance, reduce the heat transferred to the end of the second mounting portion 38, and cool the second mounting portion 38 by blowing air.
