[0027] Below, in conjunction with Figures 1 to 8 The present invention will be further described in the preferred embodiments and other embodiments. It should be noted that, without conflict, the technical features described below can be arbitrarily combined to form new embodiments.

[0028] Referring to 1-8, in a preferred embodiment, an oven is characterized by comprising: a baking cavity 3, a fixing device 7, a heating element 9, a light wave heating device 4, and a baffle 5, wherein the heating element 9 is disposed inside the baking cavity 3 or on the outer periphery of the baking cavity 3, for heating the baking cavity 3;

[0029] The baking cavity 3 is provided with a baking area 31;

[0030] The fixing device 7 includes a support plate 71 and at least one hanger 72. The support plate 71 is located above the baking area 31, and the hanger 72 is fixed to the support plate 71 and located inside the baking cavity 3. The hanger 72 is used to fix the food so that the food is located in the baking area 31. The support plate 71 can rotate along a vertically set first rotation axis a.

[0031] The light wave heating device 4 is located outside the baking area 31. The light wave heating device 4 includes a radiating element 42 and a projection port 431. The energy generated by the radiating element 42 is projected outward from the projection port 431, which is oriented towards the baking area 31.

[0032] The baffle 5 is made of opaque, high-temperature resistant material. The baffle 5 is located on the side of the baking cavity 3 opposite to the projection port 431 to block and reflect the energy radiated from the projection port 431.

[0033] By setting the light wave heating device 4 and the heating element 9, the heating element 9 maintains the temperature inside the baking cavity 3, the light wave heating device 4 enhances the baking effect on the food, and the projection port 431 faces the baking area 31 to reduce the energy loss of the light wave heating device 4, quickly baking the food to ensure the taste of the food; by setting the baffle 5 on the side of the baking cavity 3 opposite to the projection port 431, the energy loss is further reduced, and the light wave heating device 4 is prevented from directly shining on the baking cavity 3, which would accelerate the wear of the side wall of the baking cavity 3.

[0034] In a preferred embodiment, the projection direction of the projection port 431 of the oven of this utility model is set in the horizontal direction, which reduces the travel distance of the energy generated by the light wave heating device 4 to the baking area 31, and further reduces energy loss.

[0035] In a preferred embodiment, a through groove 32 is provided on one side wall of the baking cavity 3 of the oven of this utility model. The light wave heating device 4 is installed in the through groove 32, and the projection port 431 extends into the baking cavity 3. By setting the through groove 32, the light wave heating device 4 is not completely located in the baking cavity 3, which is conducive to the heat dissipation of the light wave heating device 4.

[0036] In a preferred embodiment, the baffle 5 of the oven of this utility model is provided with a reflective surface 51, which faces the projection port 431, so as to realize that the energy passing through the baking area 31 is reflected back to the baking area 31, thereby further reducing the energy loss of the light wave heating device 4.

[0037] In a preferred embodiment, the fixing device 7 of the oven of this utility model further includes a first driving mechanism 73 and a planetary gear system 74. The planetary gear system 74 includes at least one planetary gear 741. All the planetary gears 741 are arranged in a circular array on the support plate 71 with the first rotation axis a as the axis. Each planetary gear 741 corresponds to a hanger 72. Each hanger 72 includes a fixed shaft 721 and a hook 722. One end of the fixed shaft 721 is connected to the planetary gear 741, and the other end of the fixed shaft 721 is connected to the hook 722. The output shaft of the first driving mechanism 73 is connected to the planetary gear system 74 to drive the planetary gear and the support plate 71 to rotate, so that the hanger 72 rotates with the support plate 71 around the first rotation axis a and also rotates with its corresponding planetary gear. This also ensures that the food suspended on the hook 722 is directly irradiated by the light wave heating device 4 from all directions.

[0038] In a preferred embodiment, the oven of this utility model further includes a camera 100, a circuit board 300, and a lifting mechanism 6. The light wave heating device 4 includes a reflective cavity 432, which has a projection port 431. The reflective cavity 432 is ellipsoidal and includes a first focal point 4321 and a second focal point 4322.

The second focal point 4322 is located outside the reflective cavity 432, and the baking area 31 is located at the second focal point 4322. The camera 100 and the lifting mechanism 6 are both electrically connected to the circuit board 300. The fixing device 7 is connected to the lifting mechanism 6. The camera 100 monitors... The direction is towards the baking area 31. When the camera 100 detects that the second focal point 4322 does not coincide with the food located in the baking area 31, it feeds back a first detection signal. The circuit board 300 controls the lifting mechanism 6 to work according to the first detection signal. The lifting mechanism 6 drives the fixing device 7 to move in the up and down direction. When the camera 100 detects that the second focal point 4322 coincides with the food in the baking area 31, it feeds back a second detection signal. The circuit board 300 controls the lifting mechanism 6 to stop working according to the second detection signal. For foods with different lengths, they can be placed at different heights in the baking area 31 to ensure that the food is always located at the second focal point 4322 during the baking process, further reducing energy loss. Furthermore, in its implementation, when the camera 100 detects that the second focal point 4322 does not coincide with the food located in the baking area 31, it feeds back a second detection signal. The circuit board 300 controls the motor on the light wave heating device 4 to work according to the second detection signal. The motor can finely adjust the upward or downward angle of the projection port 431 of the light wave heating device 4, so that the second focal point 4322 coincides with the food in the baking area 31.

[0039] In a preferred embodiment, the lifting mechanism 6 of the oven of this utility model includes a second driving mechanism 61, a fixed frame 62 and a screw 63. The fixed frame 62 is fixed relative to the baking cavity 3. The second driving mechanism 61 is fixed to the fixed frame 62.

The baking cavity 3 is open on the side facing the second opening 12 so as to facilitate observation of the baking situation at any time.

[0041] In a preferred embodiment, the light wave heating device 4 of the oven of this utility model further includes a mounting base 41, a reflector 43, and a fan 44. The mounting base 41 is fixed in the accommodating cavity 11, and the mounting base 41 has a mounting cavity 411 inside. A first opening 412 is opened on one side of the mounting base 41. The fan 44 is disposed in the mounting base 41, and the fan 44 communicates with the mounting cavity 411 and the outside of the accommodating cavity 11.

[0042] In a preferred embodiment, the heating element 9 of the oven of this invention is a microwave generator, and the heating element 9 is disposed inside the baking cavity 3. In other embodiments, the heating element 9 is an electric heating tube.

[0043] The working principle of this oven is as follows: During operation, the prepared ingredients are placed on the hook 722, the cabinet door 2 is closed, and the oven is started. The circuit board 300 controls the heating element 9 and the light wave heating device 4 to work. When the camera 100 detects that the second focal point 4322 does not coincide with the ingredients in the cooking cavity, it feeds back a first detection signal. The circuit board 300 controls the second drive mechanism 61 to work according to the first detection signal. The second drive mechanism 61 drives the fixing device 7 to move up and down. When the camera 100 detects that the second focal point 4322 coincides with the ingredients in the baking area 31, it feeds back a second detection signal. The circuit board 300 controls the second drive mechanism 61 to stop working according to the second detection signal. At the same time, the circuit board 300 controls the first drive mechanism 73 to work, so that the hanging rack 72 rotates around the first rotating axis a with the support plate 71 and rotates on its own axis with its corresponding star gear until baking is completed.

[0044] The beneficial effect of this oven is that by setting the light shield to protrude from the projection port along the projection direction, so as to block one side of the projection port, the light coming out of the projection port is blocked by the light shield during cooking, avoiding direct light shining into the user's eyes, effectively solving the problem of glare.
