[0032] Example 1

[0033] like Figure 1-5 As shown, a dual-cavity cooking device 100 includes a housing 8, within which an upper cavity 1 and a lower cavity 2 are disposed. The upper cavity 1 has a first inner pot 11, and the lower cavity 2 has a second inner pot 21. The upper cavity 1 is located above the lower cavity 2. The dual-cavity cooking device 100 also includes a steam generator 3 and a water tank 4. A second connecting pipe 32 is provided at the bottom of the steam generator 3 and connected to the water tank 4 via a pump assembly 5. This arrangement allows excess water in the steam generator 3 to be re-transferred to the water tank 4, effectively preventing the growth of bacteria and microorganisms within the steam generator 3 and avoiding corrosion. It also prevents the generation of large amounts of wet steam during use of the steam oven, ensuring that the steam heat exchange efficiency meets the required standards.

[0034] As an example of the present invention, a first connecting pipe 31 and a second connecting pipe 32 are respectively provided at the top and bottom of the steam generating device 3. The pump assembly 5 includes a first pump 51 and a second pump 52. The first pump 51 is located between the water tank 4 and the first connecting pipe 31, and the second pump 52 is located between the water tank 4 and the second connecting pipe 32. This arrangement enables the first pump 51 to transport water from the water tank 4 to the steam generating device 3. After the steaming and baking operation is completed, the second pump 52 is used to drain all the water in the steam generating device 3 back into the water tank 4, thereby ensuring that no water remains in the steam generating device 3.

[0035] As an example of the present invention, a mounting plate 15 is provided at the top of the upper cavity 1, the water tank 4 is mounted on the mounting plate 15, the steam generator 3 is located at the rear of the upper cavity 1 and at the top of the lower cavity 2, and the steam generator 3 is provided with an outlet pipe 33 for supplying steam into the lower cavity 2. This arrangement is compact, fully utilizes the internal space of the dual-cavity cooking device 100, and is easy to manufacture and process.

[0036] Preferably, the mounting plate 15 is provided with a first air guide 13, a first fan 14, and an electronic control board. A first air duct is formed between the first air guide 13 and the mounting plate 15, and the magnetron 9 is disposed within the first air duct. The electronic control board is located between the water tank 4 and the first fan 14, and the first fan 14 is located at the inlet of the first air duct. This arrangement allows the first fan 14 to blow air toward the magnetron 9 to dissipate heat, while also driving air flow near the electronic control board, thereby facilitating heat dissipation from the board.

[0037] The upper cavity 1 also includes a waveguide box, a stir plate, etc., the specific structure and assembly relationship of which are all existing technologies and will not be described in detail here. As an example of the present invention, the dual-cavity cooking device 100 also includes a first bracket 6, which is located at the rear of the upper cavity 1 and the top of the lower cavity 2 and is used to fix the steam generating device 3. A first opening is provided on the front side of the first inner pot 11, and the upper cavity 1 also includes a first door assembly 12, which is openably provided at the first opening.

[0038] Preferably, the first air duct is connected to the first inner container 11. This arrangement enables a single first fan 14 to drive airflow into the first inner container 11, thereby discharging the fumes generated within the first inner container 11. Preferably, a frequency converter is provided within the first air duct, located on the air inlet side of the magnetron 9. This arrangement allows the first fan 14 to simultaneously dissipate heat from the frequency converter and the magnetron 9, thereby meeting experimental requirements.

[0039] A second opening is provided on the front side of the second inner container 21. The lower chamber 2 further includes a second door assembly 22, which is openably and closably provided at the second opening. The second door assembly 22 is provided with a handle 221. When the second door assembly 22 needs to be opened or closed, the user can complete the opening or closing action by pulling the handle 221, thereby making the opening or closing of the second door assembly 22 more convenient.

[0040] Preferably, a door duct 223 is provided in the second door assembly 22, an air inlet 222 is provided at the bottom of the door duct 223, and an air outlet 224 connected to the intermediate duct 271 is provided at the top of the door duct 223; a top plate 28 is provided on the top of the lower cavity 2, and a partition 27 and a second air guide cover 26 are provided on the side of the top plate 28 away from the second inner tank 21 in sequence, an intermediate duct 271 is formed between the partition 27 and the top plate 28, an outlet duct 272 is formed between the partition 27 and the second air guide cover 26, the inlet end of the intermediate duct 271 is arranged opposite to the air outlet 224, and a second fan 23 is provided at the outlet end of the intermediate duct 271 for supplying air to the outlet duct 272.

[0041] This arrangement utilizes a second fan 23 to direct cool air from the outside through the air inlet 222 into the door duct 223, and then into the intermediate duct 271 and the outlet duct 272. As the cool air flows through the intermediate duct 271 and the outlet duct 272, it dissipates heat generated by the lower chamber 2. This creates a double barrier between the upper and lower chambers 1 and 2, preventing heat from being transferred upward from the lower chamber 2 to the upper chamber 1. Furthermore, the cool air entering the door duct 223 lowers the surface temperature of the second door assembly 22, preventing accidents such as burns.

[0042] Preferably, a third fan 24 and a heating assembly 25 are disposed at the rear of the second inner pot 21. The heating assembly 25 is located on at least one of the top, bottom, or rear of the second inner pot 21, and the third fan 24 is located at the rear of the second inner pot 21. This arrangement ensures that food is evenly heated from multiple directions, preventing food from being overheated on one side while undercooked on the other, thereby improving the taste and quality of the food. Furthermore, the third fan 24 creates a hot air circulation within the second inner pot 21, further enhancing the heating effect, making the food heat more evenly and shortening cooking time.

[0046] Preferably, a horizontally positioned lower base plate 17 is provided at the bottom of the first inner pot 11, and a top plate 28 is provided above the second inner pot 21. The lower base plate 17 is located above the top plate 28. The first fixing plate 18 is respectively connected to the first inner pot 11 and the lower base plate 17, and the second fixing plate 29 is respectively fixedly connected to the second inner pot 21 and the top plate 28. This arrangement increases the stress points of the first fixing plate 18 and the second fixing plate 29, while forming the first inner pot 11, the lower base plate 17, the second inner pot 21, and the top plate 28 into an organic whole, thereby ensuring stable and reliable assembly of the dual-cavity cooking device 100.

The lower base plate 17 is fixedly provided with a first crossbeam 19 on the side away from the top plate 28. The first fixing plate 18 is fixedly connected to the first support member 20 and the first crossbeam 19 respectively. This arrangement can improve the connection tightness of the first fixing plate 18 and the first support member 20, so that the upper cavity 1 itself forms an organic whole.

The positioning hole 1111 is provided on the first flange 111, and the inserting piece 181 is provided on the first fixing plate 18 at a position corresponding to the positioning hole 1111. This simple structure allows for rapid positioning of the first fixing plate 18 and the first inner liner 11, further improving assembly efficiency. It also increases the contact area between the first fixing plate 18 and the first inner liner 11 to disperse the applied force.

[0050] Preferably, there are at least two plug-in plates 181 arranged perpendicular to each other. This arrangement ensures that the plug-in plates 181 are inserted into the limiting holes 1111 in the horizontal and vertical directions, thereby limiting the first fixing plate 18 on the vertical plane and further improving positioning accuracy and assembly efficiency.

This arrangement utilizes the fixing member 16 to improve the assembly strength and stability of the upper cavity 1. At the same time, the connecting rod 10 cooperates with the connecting member 7 to form an organic whole with the upper cavity 1 and the lower cavity 2, ensuring that the dual-cavity cooking device 100 is always securely assembled and stable during transportation and handling.
