[0032] With the development of intelligent home appliances, by adding camera functions to steam ovens, more practical functions can be added to the ovens, such as ingredient recognition before cooking, doneness recognition during cooking, and video sharing of the cooking process after cooking.

[0033] However, in the steam-bake mode, the temperature inside the cooking cavity is lower. At the same time, the steam-bake mode will produce a large amount of water vapor, which may cause some water vapor to gather on the insulating glass under the camera, thus affecting the clarity of the lens shooting.

[0034] See also Figure 1 and Figure 2 A camera mechanism 10 according to an embodiment of the present utility model is used in a cooking appliance 100 . The camera mechanism 10 includes a protective component 12 , a camera component 14 and a heating element 16 .

[0035] The protection component 12 is disposed on the light incident side of the camera component 14 , and the heating element 16 is used to heat the protection component 12 .

[0036] The camera mechanism 10 mentioned above can heat the protective component 12 by installing a heating element 16 on the protective component 12, so that water mist will not or is unlikely to form on the protective component 12, thereby ensuring the shooting clarity of the camera component 14.

[0037] Specifically, the cooking appliance 100 includes a cooking cavity 66 for cooking, and the camera mechanism 10 is mounted on the cooking appliance 100. The cooking cavity 66 has a hole so that the camera mechanism 10 can capture the state of the food in the cooking cavity 66. Since the cooking appliance 100 has cooking functions such as steaming and baking, its operating temperature can reach a high temperature of more than 200 degrees Celsius. In order to prevent the camera mechanism 10 from being overheated, a protective component 12 is provided. The protective component 12 is provided on the light incident side of the camera component 14, and the camera component 14 can capture the food in the cooking cavity 66 through the protective component 12. The protective component 12 can be used to isolate the camera component 14 from the high temperature in the cooking cavity 66, thereby preventing the camera mechanism 10 from being damaged or having its service life shortened due to the overheating of the camera component 14.

[0038] In the steam-bake mode of the oven, the temperature in the cooking cavity 66 is lower than that in the baking mode, and the food is heated by a large amount of steam. At this time, the steam may gather on the protective component 12, causing the picture taken by the camera component 14 to be unclear.

[0039] Based on this, an embodiment of the utility model provides a camera mechanism 10, and a heating element 16 is added to the protective component 12. When the protective component 12 in front of the camera component 14 is fogged, the heating element 16 is started to heat the protective component 12. After the temperature of the protective component 12 increases, the water mist gathered on the protective component 12 will quickly evaporate and disappear, and the water mist can be prevented from gathering again. As a result, the protective component 12 can have the effect of defogging and anti-fogging, thereby ensuring that the camera component 14 can continue to capture clear pictures.

[0040] See also Figure 1 and Figure 3 , Figure 4 In some embodiments, the protective component 12 includes a light-transmitting member 18, a first bracket 20 and a second bracket 22. The light-transmitting member 18 is installed on the first bracket 20. The first bracket 20 includes a first connecting tube 24. The second bracket 22 includes a receiving groove 26. The heating element 16 is sleeved on the outer wall of the receiving groove 26. The receiving groove 26 is sleeved on the first connecting tube 24, so that the heating element 16 can heat the protective component 12.

[0041] In this way, the heating element 16 is sleeved on the second bracket 22 , and the heat can be conducted from the second bracket 22 and the first bracket 20 to the light-transmitting element 18 , so that the temperature of the light-transmitting element 18 is increased and the water mist accumulated on the light-transmitting element 18 is eliminated.

[0042] Specifically, Figure 3 As shown, the heating element 16 is sleeved on the second bracket 22, the second bracket 22 is connected to the first bracket 20, and the light-transmitting element 18 is installed on the first bracket 20. When the heating element 16 is heated, the heat can be conducted from the second bracket 22 and the first bracket 20 to the light-transmitting element 18. When the heating element 16 is working, the light-transmitting element 18 can be heated to about 100 degrees Celsius. After the temperature of the light-transmitting element 18 is increased, the water mist gathered on the light-transmitting element 18 will evaporate quickly, so that the water mist gathered on the light-transmitting element 18 can be eliminated.

[0043] See also Figure 3 and Figure 4 , Figure 5 In some embodiments, the camera assembly 14 includes a camera 28 and a camera bracket 30, the camera 28 is installed on the camera bracket 30, the second bracket 22 has a first through hole 34, the light-transmitting member 18 is accommodated in the first connecting tube 24, and the camera 28 shoots the interior of the cavity 68 of the cooking appliance 100 through the first through hole 34 and the light-transmitting member 18.

[0044] In this way, the protection component 12 is fixed to the opening of the cooking cavity 66 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 68 of the cooking appliance 100 through the first through hole 34 and the light-transmitting member 18.

[0045] Specifically, in order to photograph the food inside the cooking cavity 66, an opening is made in the cavity 68 of the cooking cavity 66, 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 66. Thus, the camera component 14 can photograph the interior of the cooking cavity 66 through the protective component 12. The protective component 12 blocks the opening, which can prevent steam leakage in the cooking cavity 66 and isolate the camera component 14 from the high temperature in the cooking cavity 66.

[0046] 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 18 is accommodated in the first connecting tube 24 of the first bracket 20. The second bracket 22 has a first through hole 34. The camera 28 can shoot the interior of the cooking cavity 66 through the first through hole 34 and the light-transmitting member 18.

[0047] like Figure 5 As shown, in one embodiment, 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 is provided with a mounting hole 40, and the second mounting portion 38 is penetrated with the mounting hole 40 so that the second mounting portion 38 is fixedly connected to the camera bracket 30. 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 be increased too much.

[0048] See also Figure 3 and Figure 4 In some embodiments, the camera mechanism 10 includes a heat shield 42 , 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 42 is disposed between the second bracket 22 and the camera bracket 30 .

[0049] In this way, it is possible to prevent the heating element 16 from causing the temperature of the camera assembly 14 to be too high when heating the protective assembly 12 .

[0050] Specifically, the camera bracket 30 is fixedly connected to the second bracket 22, and the heating element 16 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 18. The heat insulation board 42 is arranged between the second bracket 22 and the camera bracket 30, which can significantly reduce the temperature transfer of the heating element 16 to the camera assembly 14 after the heating, thereby ensuring that the camera assembly 14 is in a relatively constant temperature and suitable for work.

[0051] In one embodiment, the heat insulation board 42 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 cooking appliances 100 with high working temperatures.

[0052] See also Figure 3 and Figure 4 In some embodiments, the light-transmitting member 18 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 disposed 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.

[0053] In this way, the first light-transmitting member 44 and the second light-transmitting member 46 can reduce the temperature in the cooking cavity 66 from being transferred to the camera assembly 14 . Meanwhile, the light-transmitting member 18 does not affect the shooting of the camera assembly 14 .

[0054] 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 68 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 assembly 12 can achieve a good heat insulation effect through the two layers of light-transmitting members 18 and the sealed cavity 68 therebetween.

[0055] The first direction is Figure 3 The up and down directions shown in .

[0056] 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.

[0057] 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.

[0058] See also Figure 3 and Figure 4 In some embodiments, the first connecting tube 24 has a step portion 50 at one end away from the second bracket 22. When the accommodating groove 26 is sleeved on the first connecting tube 24, the step portion 50 presses against the periphery of the first light-transmitting member 44, and the bottom of the accommodating groove 26 presses against a surface of the second light-transmitting member 46 to limit the positions of the first light-transmitting member 44 and the second light-transmitting member 46 along the first direction.

[0059] In this way, the step portion 50 and the receiving groove 26 define a receiving space for the first light-transmitting member 44 and the second light-transmitting member 46 and define the positions of the first light-transmitting member 44 and the second light-transmitting member 46 along the first direction.

[0060] Specifically, when the first bracket 20 is fixedly connected to the second bracket 22, the second bracket 22 is located on the outside of the cavity 68 of the cooking cavity 66, and the first bracket 20 is located on the inside of the cavity 68 of the cooking cavity 66. The first connecting tube 24 passes through the opening of the cavity 68 of the cooking cavity 66, and the receiving groove 26 of the second bracket 22 is sleeved on the first connecting tube 24. The first bracket 20 and the second bracket 22 are fixedly connected by fasteners, so that the wall of the cavity 68 of the cooking cavity 66 is clamped between the first bracket 20 and the second bracket 22, so that the protective component 12 can be fixedly installed at the opening of the cavity 68 of the cooking cavity 66.

[0061] The accommodating groove 26 of the second bracket 22 is sleeved on the first connecting tube 24, and the step portion 50 and the accommodating groove 26 define the accommodating space of the first light-transmitting member 44 and the second light-transmitting member 46. The first light-transmitting member 44 and the second light-transmitting member 46 are arranged in the first connecting tube 24, and the step portion 50 presses against the periphery of the first light-transmitting member 44, and the bottom of the accommodating groove 26 presses against a surface of the second light-transmitting member 46. The wall of the first connecting tube 24 defines the positions of the first light-transmitting member 44 and the second light-transmitting member 46 in a plane perpendicular to the first direction, thereby the positions of the first light-transmitting member 44 and the second light-transmitting member 46 can be defined by the first connecting tube 24 and the accommodating groove 26.

[0062] See also Figure 3 and Figure 4 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 68 of the cooking cavity 66 of the cooking appliance 100, the first connecting tube 24 is passed through the opening of the cavity 68, and the fixing portion 52 abuts against the inner wall of the cavity 68.

[0063] In this way, the first bracket 20 is fixedly connected to the second bracket 22 through the opening of the cavity 68 through the first connecting tube 24 , and the fixing portion 52 abuts against the inner wall of the cavity 68 , so that the first bracket 20 can be fixed to the inner wall of the cavity 68 .

[0064] Specifically, the first bracket 20 is installed from the inside to the outside of the cavity 68 of the cooking cavity 66, and the first connecting tube 24 passes through the opening of the cavity 68. The first connecting tube 24 has a fixing portion 52 on the outer periphery away from the second bracket 22, and the fixing portion 52 can abut against the inner wall surface of the cavity 68. The fixing portion 52 can fix and support the first connecting tube 24.

[0065] See also Figure 4In some embodiments, the fixing portion 52 is provided with a sealing groove 54, the first bracket 20 includes a second sealing member 56, and the second bracket 22 includes a third sealing member 58. When the camera mechanism 10 is installed in the cavity 68 of the cooking cavity 66 of the cooking appliance 100, the second sealing member 56 is accommodated between the sealing groove 54 and the inner wall surface of the cavity 68, and the third sealing member 58 is arranged between the second bracket 22 and the outer wall surface of the cavity 68.

[0066] In this way, the protection assembly 12 can seal the opening of the cavity 68 to prevent the steam in the cooking cavity 66 from leaking.

[0067] Specifically, when the camera mechanism 10 is installed in the cavity 68 of the cooking cavity 66 of the cooking appliance 100, the first bracket 20 contacts the inner wall surface of the cavity 68 of the cooking cavity 66, and the second bracket 22 contacts the outer wall surface of the cavity 68. The second seal 56 and the third seal 58 are respectively arranged between the contact surfaces of the first bracket 20 and the second bracket 22 and the cavity 68. When the first bracket 20 and the second bracket 22 are fixedly connected to the cavity 68 of the cooking cavity 66, the opening of the cavity 68 can be sealed to prevent steam leakage in the cooking cavity 66.

[0068] Optionally, the second sealing member 56 and the third sealing member 58 are high temperature resistant silicone sealing rings, thereby ensuring that the sealing members have a long service life and avoiding sealing failure and steam leakage.

[0069] Optionally, the second seal 56 is a high temperature resistant silicone seal ring, the third seal 58 is a metal gasket, the first bracket 20 and the second bracket 22 are made of metal. In this way, the camera mechanism 10 can be used on a cooking appliance 100 with a microwave mode. The first bracket 20, the second bracket 22 and the third seal 58 are all made of conductive materials and are connected to the inner wall of the cavity 68 to form a microwave shielding body to prevent microwave leakage.

[0070] See also Figure 4 In some embodiments, the heating element 16 includes a connecting portion 60 and a surrounding portion 62, the surrounding portion 62 is connected to the connecting portion 60, the surrounding portion 62 is sleeved on the outer wall of the accommodating groove 26, and the connecting portion 60 is electrically connected to an external power source to increase the temperature of the heating element 16.

[0071] In this way, the contact area between the heating element 16 and the second bracket 22 is large, which can improve the heating efficiency.

[0072] Specifically, the surrounding portion 62 of the heating element 16 is annular and surrounds the outer edge of the second bracket 22. When the connecting portion 60 is energized with an external power source, the heat of the surrounding portion 62 rises and is evenly transferred to the second bracket 22. The first connecting tube 24 of the first bracket 20 is accommodated in the accommodating groove 26 of the second bracket 22, so that the temperature of the second bracket 22 can be evenly transferred to the first bracket 20 and the light-transmitting element 18 installed in the first connecting tube 24. In this way, rapid and uniform heating can be achieved, and heating efficiency can be improved.

[0073] Optionally, the first bracket 20 and the second bracket 22 are made of metal, so that the first bracket 20 and the second bracket 22 can withstand the high temperature of the cooking cavity 66 in different modes and make the heat conduction effect of the heating element 16 better.

[0074] Optionally, the first bracket 20 and the second bracket 22 are made of metal, and the camera bracket 30 is made of plastic. The camera bracket 30 made of plastic can prevent the temperature of the first bracket 20 and the second bracket 22 from being transferred to the camera 28 too quickly, thereby affecting the service life of the camera 28.

[0075] In summary, a heating element 16 is added to the steam oven camera mechanism 10. When water mist gathers on the light-transmitting element 18, the heating element 16 is started to heat the camera light-transmitting element 18. After the temperature of the camera glass reaches a relatively high temperature (around 100°C), the water mist can disappear quickly, thereby not affecting the camera shooting.

[0076] See also Figure 2 A cooking appliance 100 according to an embodiment of the present invention includes a camera mechanism 10 according to any one of the above embodiments.

[0077] The cooking appliance 100 described above can heat the protective component 12 by installing a heating element 16 on the protective component 12 , so that water mist will not or is unlikely to form on the protective component 12 , thereby ensuring the shooting clarity of the camera component 14 .

[0078] Specifically, the cooking appliance 100 includes but is not limited to a steamer, an oven, and other integrated cooking devices with a steam cooking function.

[0079] The cooking appliance 100 includes a cooking cavity 66 for cooking. The camera mechanism 10 is mounted on the cooking appliance 100 . The cooking cavity 66 has an opening so that the camera mechanism 10 can capture the state of food in the cooking cavity 66 .

[0080] The camera mechanism 10 can be installed on the top of the cooking appliance 100 or on any side of the cooking cavity 66.

[0081] Preferably, the camera mechanism 10 is installed on the top of the cooking appliance 100, so that the shooting angle of the camera mechanism 10 is consistent with the angle of view observed by the user through the observation window on the door of the cooking appliance 100, which is convenient for the user to observe, and at this angle of view, the state of the food can be clearly and completely captured.

[0082] A heating element 16 is added to the camera mechanism 10 of the steam oven. When the camera 28 is shooting, it can identify and judge whether there is water mist on the light-transmitting element 18 of the protective component 12 based on the clarity of the shooting. When the light-transmitting element 18 is identified to be foggy, the heating element 16 is started to heat the camera light-transmitting element 18. After the temperature of the camera glass reaches a relatively high temperature (around 100°C), the water mist can quickly disappear, thereby not affecting the camera shooting.
