[0064] Support 1;

[0065] A heating device is mounted on the support base 1. The heating device includes an upper baking pan 2 and a heating element 5 for heating the upper baking pan 2. The upper baking pan 2 is provided with an air inlet 21, and an upper cooking zone is provided on the upper side of the upper baking pan 2.

[0066] An oil fume filtration device is installed on the support base 1. The oil fume filtration device includes an oil fume filter 4, a fan 14, and at least one air outlet. A first air inlet channel is provided between the air inlet end of the oil fume filter 4 and the upper cooking area. The first air inlet channel passes through the air inlet hole 21. The air outlet end of the oil fume filter 4 is connected to the air inlet end of the fan 14, and the air outlet end of the fan 14 is connected to the air outlet.

[0067] The fan 14 can be a turbo fan.

[0068] In some specific implementations, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the air outlet is located on the outer periphery of the upper baking pan 2 and faces upwards. The upward-facing air outlet avoids the problem of hot air blowing directly at people. Furthermore, the higher-temperature air discharged from the outlet forms an insulating layer between the upper baking pan 2 and the surrounding cooler air, thereby reducing heat exchange between the upper baking pan 2 and the cooler air, thus reducing heat loss from the upper baking pan 2 and further improving the oven's heat utilization efficiency.

[0069] In some specific embodiments, to further isolate the upper baking pan 2 from the surrounding air, there are two air outlets, located on the left rear side and right rear side of the upper baking pan 2, respectively. The air outlet of the fan 14 is connected to each air outlet.

[0080] The support base 1 has a plurality of support platforms on its outer periphery, including a first support platform 11a located on the left rear side of the support base 1, a second support platform 11b located on the right rear side of the support base 1, and a third support platform 7 located on the front side of the support base 1.

[0081] The first support platform 11a, the second support platform 11b, and the third support platform 7 are all provided with support steps 6 for supporting the lower baking pan 3; the support assembly includes three support steps 6. The three support steps 6 can circumferentially limit the lower baking pan 3, making the connection between the lower baking pan 3 and the support base 1 more stable.

[0082] The third support platform 7 is equipped with an operation panel for displaying or setting the temperature and performing on / off operations.

[0083] Among them, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the support assembly also includes a plurality of first support members 31 located between the lower baking pan 3 and the upper baking pan 2, and a plurality of second support members 16 located between the lower baking pan 3 and the support base. The lower end of each first support member 31 passes through the lower baking pan 33 and is bent to form a bent portion 311 that fits on the lower baking pan 3. The plurality of bent portions 311 and the plurality of second support members 16 are fixedly connected one-to-one by screws, and the screws pass through the lower baking pan 3 and the bent portion 311 from top to bottom and are screwed into the second support member 16.

[0084] Each of the first support members 31 is provided with a heating tube 5 slot 312, and the heating tube 5 can be detachably snapped into all the slots 312; the positive and negative poles of the heating tube 5 pass downward through the lower baking pan 3 and are connected to the interface of the support base 1.

[0085] The lower baking pan 3 has several cheese tray positioning grooves 32. Cheese trays 33 can be placed on the cheese trays 33 for baking cheese.

[0086] In some specific embodiments, to facilitate cleaning and other operations of the fume filter 4, the fume filter 4 is detachably connected to the support base 1. One specific structure is that the support base 1 has an annular slot 19 with the groove facing upwards, the lower end of the fume filter 4 has an annular insertion part 426, and the lower baking tray 3 has a clearance hole. The annular insertion part 426 passes through the clearance hole and is detachably inserted into the annular slot 19.

[0087] The oil fume filter 4 has a third channel 15 extending from top to bottom between its air outlet and the air inlet of the fan 14.

[0088] In some specific implementations, such as Figures 1 to 7 as well as Figure 8 As shown, the fume filter 4 includes a first filter cover 41 located on the upper side, a second filter cover 42 located on the lower side, and a fume filter layer located between the first filter cover 41 and the second filter cover 42; the fume filter layer preferably includes a filter mesh layer 43 located on the upper side and an activated carbon fiber layer 44 located on the lower side of the filter mesh layer 43.

[0089] The top of the first filter cover 41 is provided with a plurality of first filter holes 413, and the top of the second filter cover 42 is provided with a plurality of second filter holes 423.

[0090] Specifically, the first filter cover 41 is disposed on the outside of the second filter cover 42.

An elastic element 101 is provided between the lower end of the probe holder 91 and the support base. Specifically, the guide portion 10 consists of two columns, and the probe holder 91 has two through holes through which the two columns pass. The elastic element 101 is a spring sleeved on the columns. The spring drives the upper end of the temperature probe 9 to always be in contact with the upper baking pan 2, thereby performing temperature measurement.

[0095] Working principle explanation:

[0096] In this embodiment, the smokeless oven has an upper baking pan 2 for grilling food and a lower baking pan 3 for baking cheese products via a cheese pan 33. When the fan 14 is running, the fumes emitted from the upper baking pan 2 are drawn into the fume filter 4 through the air inlet 21 for filtration. The filtered clean air is then discharged upwards through the air outlet. The upward-discharged hot air creates an isolation effect between the upper baking pan 2 and the surrounding air, thereby reducing heat loss from the upper baking pan 2 and improving its thermal efficiency.
