[0042] like Figure 3As shown, the outer shell 1 includes a front shell plate, a rear shell plate, a left shell plate, a right shell plate, an upper shell plate, and a lower shell plate with openings. The two plates can be fixed together by means of screw connection, welding, or integral bending. In this embodiment, the left shell plate, the upper shell plate, and the right shell plate are integrally bent, and then the front shell plate, the lower shell plate, and the rear shell plate are fixed in sequence by screws to form a square outer shell 1.

[0043] like Figure 2 , 4 As shown, an inner liner 2 is fixed inside the outer shell 1. The inner liner 2 has a left side plate, a right side plate, a top plate, a bottom plate, and a back plate. In this embodiment, the top plate and the back plate are integrally formed, as are the left side plate, the bottom plate, and the right side plate. The two components are then fixed together by welding to form the inner liner 2 with a food processing cavity. The length and height of the inner liner 2 are smaller than those of the outer shell 1, but its width is basically the same as that of the outer shell 1. The inner liner 2 is installed in the middle of the outer shell 1, and the inlet edge of its food processing cavity is fixedly connected to the opening edge of the front shell plate. The back plate of the inner liner 2 contacts and is fixedly connected to the rear shell plate of the outer shell 1, thereby forming gap spaces between the lower shell plate and the back plate, between the left shell plate and the left side plate, between the right shell plate and the right side plate, and between the upper shell plate and the top plate.

[0044] like Figure 2 As shown, the microwave generator 4 is installed on one side wall of the inner liner 2 and is used to generate microwaves into the food processing cavity. A microwave mounting cavity 12 is provided between the inner liner 2 and the outer shell 1.

The motor is installed above the top cover plate 22, and the heating fan blades 521 are installed below the top cover plate 22 via the main shaft of the motor 523 and are located at the center of the air blasting heating chamber 221. The heating element 51 is an electric heating tube, which is arranged around the heating fan 52. The through holes 211 include an air inlet through hole located below the heating fan 52 for supplying air to the air blasting heating chamber 221 and an air outlet through hole located below the electric heating tube for supplying air to the air blasting heating chamber 221. When the air frying function is required, the heating element 51 and the heating fan 52 work simultaneously. The air in the food processing cavity enters through the air inlet and flows to the surroundings. After being heated by the heating element 51, it enters the food processing cavity through the air outlet. The heated gas then cooks the food, achieving the air frying effect.

[0047] In this embodiment, the mesh cover plate 21 is integrally formed with the top plate of the inner liner 2, and the top cover plate 22 is fixed above the top plate to form the air fryer heating chamber 221. In another embodiment, the top cover plate 22 is integrally formed with the top plate of the inner liner 2, and the mesh cover plate 21 is fixed below the top plate to form the air fryer heating chamber 221. In addition, the main shaft of the motor 523 is also provided with cooling fan blades 522 for dissipating heat from the motor 523, and the cooling fan blades 522 are installed above the top cover plate 22.

[0048] like Figure 6 , 7 As shown, the smoking device 6 has a smoking channel 62 disposed between the outer shell 1 and the inner liner 2 and a smoking fan 61 disposed within the smoking channel 62. The smoking channel 62 has at least one smoking port 621 disposed at the bottom of the outer shell 1 and at least one exhaust port 622 disposed on the outer shell 1.

[0049] In this embodiment, the smoke extraction fan 61 is located above the rear side of the inner liner 2, with fan smoke inlets 611 on its left and right sides and a fan smoke outlet 612 on its middle side wall. By rotating the smoke extraction fan 61 back and forth, the position of the fan smoke outlet 612 can be changed without changing the position of the fan smoke inlet 611, so as to meet different installation requirements.

[0050] like Figure 2As shown, the smoke extraction channel 62 also includes a bottom smoke extraction channel 623 located between the bottom of the inner liner 2 (bottom plate) and the bottom of the outer shell 1 (lower shell plate), a left / right smoke extraction channel 624 located between the left / right sides of the inner liner 2 (left side plate / right side plate) and the left / right sides of the outer shell 1 (left shell plate / right shell plate), and a top smoke extraction channel 625 located between the top of the inner liner 2 (top plate) and the top of the outer shell 1 (upper shell plate). The bottom smoke extraction channel 623 connects to the smoke extraction port 621, where an oil fume filter component 63 is installed. The oil fume filter component 63 is preferably a multi-layer aluminum mesh used for filtering oil. The top smoke extraction channel 625 connects to the fan inlets 611 on the left and right sides of the smoke extraction fan 61.

[0051] like Figure 3 As shown, the smoke exhaust port 622 of the smoke extraction device 6 has three different options for users to choose from, and the corresponding smoke extraction fan 61 also has three installation methods, thereby realizing three different smoke extraction channels 62.

[0052] The first installation method of the smoke extraction fan 61: The smoke extraction fan 61 has its exhaust port 612 facing upwards. The upper shell plate of the outer casing 1 has a top exhaust port 622A, which is connected to an external exhaust pipe and discharged outdoors. When the smoke extraction fan 61 is working, the fumes pass sequentially through the fume filter component 63, the smoke extraction port 621, the bottom smoke extraction channel 623, the left / right side smoke extraction channels 624, the top smoke extraction channel 625, the smoke extraction fan 61, and the top exhaust port 622A, and are then discharged outdoors through the external exhaust pipe.

[0053] The second installation method for the smoke extraction fan 61: The smoke extraction fan 61's exhaust port 612 faces rearward, and the rear shell plate of the outer casing 1 has a rear exhaust port 622B, which connects to an external exhaust pipe and is discharged outdoors. When the smoke extraction fan 61 is working, the fumes pass sequentially through the fume filter component 63, the smoke extraction port 621, the bottom smoke extraction channel 623, the left / right side smoke extraction channels 624, the top smoke extraction channel 625, the smoke extraction fan 61, and the rear exhaust port 622B, before being discharged outdoors through the external exhaust pipe.

[0054] The third type of installation method for the smoke extraction fan 61: as follows Figure 7As shown, the exhaust fan 61 has its exhaust port 612 facing forward, and the front shell of the outer casing 1 has a front exhaust port 622C. An internal exhaust channel 641 is formed at the top of the outer casing 1 via a partition 64. One end of this internal exhaust channel 641 is connected to the exhaust port 612 of the exhaust fan 61, and the other end is connected to the front exhaust port 622C located on the upper front side of the outer casing 1. An activated carbon filter assembly 65 is installed on the internal exhaust channel 641, which filters the oil fumes in the air. The filtered air is then exhausted into the room through the front exhaust port 622C. When the exhaust fan 61 is working, the oil fumes pass sequentially through the oil fume filter assembly 63, the exhaust port 621, the bottom exhaust channel 623, the left / right side exhaust channels 624, the top exhaust channel 625, the exhaust fan 61, the internal exhaust channel 641, and the front exhaust port 622C before being directly exhausted into the room.

[0055] To prevent exhaust air from blowing directly onto the user, a ventilated cover 11 is provided above the front panel of the outer casing 1, forming a ventilated cavity 111. At least one vent hole 112 is provided on the top of the ventilated cover 11. The internal smoke exhaust channel 641 connects to the vent hole 112 through the ventilated cavity 111 and exhausts smoke upwards. Since the microwave oven is located above the stovetop, the vent hole 112 is not easily noticed by the user, thus enhancing its aesthetics.

[0056] Preferably, the lower shell plate is also provided with an external lighting lamp 66 for stove lighting.

[0057] like Figure 8 As shown, in this embodiment, the microwave mounting cavity 12 is located on the right side of the inner liner 2, and is formed by the right side plate of the inner liner 2, the front shell plate and the right shell plate of the outer shell 1, and several mounting plates 15. The microwave mounting cavity 12 also houses a cooling fan 13 and a circuit control board 7, which controls the operation of the microwave generator 4, the air blasting device 5, and the fumigation device 6. The top of the microwave mounting cavity 12 has an air inlet 121 communicating with the ventilation cavity 111, and the side wall of the microwave mounting cavity 12 has an air outlet 122 communicating with the food processing cavity or the fumigation channel 62. This structure is mainly used for heat dissipation of components such as the circuit control board 7, the frequency converter 41, and the magnetron 42.

[0058] In addition, a right-side smoke passage is formed between the rear mounting plate 15 and the rear shell plate, and the right-side smoke passage is connected to the fan smoke inlet 611 on the right side of the smoke fan 61.

[0059] like Figure 9 , 10 As shown, an inner liner exhaust hood 23 is provided above the inner liner 2. An exhaust channel 24 for venting the food processing cavity is provided between the inner liner 2, the inner liner exhaust hood 23 and the outer shell 1. The exhaust channel 24 includes several inner liner exhaust holes 25 opened around the top of the inner liner 2 and an outer shell exhaust port 14 provided on the top of the outer shell 1.

[0060] Specifically, several vent holes 25 are provided around the top plate of the inner cavity 2. In this embodiment, the vent holes 25 are mainly distributed on the front and left and right sides of the top plate. The inner cavity vent cover 23 includes a first vent cover 231, a second vent cover 232 installed above the top plate, and a third vent cover 233 installed on the front shell plate of the outer shell 1. The corresponding position of the front shell plate is provided with an outer shell vent 14. The third vent cover 233 is provided corresponding to the outer shell vent 14. The third vent cover 233 is a vertically installed U-shaped piece. Its upper part is sealed by the upper shell plate of the outer shell 1, and its lower end connects to the exhaust channel 24 formed between the first vent cover 231, the second vent cover 232, and the top plate. The outer shell vent 14 connects to the vent cavity 111 and the vent hole 112 of the vent cover 11. Therefore, the gas in the food processing cavity can be quickly discharged to the outside of the microwave oven through the exhaust channel 24.

[0061] Preferably, a humidity sensor 9 is provided on the inner liner exhaust hood 23 (second exhaust hood 232). The humidity sensor 9 detects the humidity of the food processing cavity through the exhaust channel 24. When the humidity reaches the threshold, it can control the microwave oven to automatically cut off the power to prevent the food from being overcooked.

[0062] like Figure 10 , 11 As shown, a door mounting strip 35 is provided on one side of the opening of the outer shell 1, and a lock hole is provided on the other side. A door device 3 is rotatably mounted on the door mounting strip 35 for sealing the food processing cavity of the inner liner 2.

[0063] Specifically, the door device 3 includes a door frame 31, an outer glass panel 32 disposed on the front side of the door frame 31, and a metal shielding plate 33 and an inner glass panel 34 disposed on the inner side of the door frame 31.
