[0108] When the cooking cavity discharges steam outward, the exhaust assembly 500 connects the cooking cavity with the exhaust buffer cavity 615. The steam in the cooking cavity enters the exhaust buffer cavity 615 through the exhaust assembly 500, then enters the exhaust cavity 210 through the third vent 613. The steam flows through the multiple sub-exhaust cavities in sequence and finally is discharged from the second exhaust port 270.

[0109] The multiple sub-exhaust cavities extend the steam discharge path, which helps to reduce the exhaust noise. The partition 240 functions as an anti-overflow baffle, effectively avoiding the phenomenon of overflowing the pot.

[0110] In some embodiments, the partition 240 divides the exhaust cavity 210 into two sub-exhaust cavities, denoted as the first sub-exhaust cavity 211 and the second sub-exhaust cavity 212. The first sub-exhaust cavity 211 faces the third vent 613. The steam in the exhaust buffer cavity 615 enters the first sub-exhaust cavity 211 through the third vent 613, and then is discharged through the second sub-exhaust cavity 212 and the second exhaust port 270.

[0111] In some embodiments, referring to Figure 9 and Figure 16 , one end of the exhaust cavity 210 is open, the inner lining 610 closes the open end of the exhaust cavity 210, and the third vent 613 communicates the exhaust cavity 210 with the exhaust buffer cavity 615.

[0112] One end of the exhaust cavity 210 is open. On the one hand, it is convenient for processing; on the other hand, it is convenient to form a closed exhaust cavity 210 after being fixedly installed with the inner lining 610.

[0113] A first exhaust gap 251 is formed between the partition portion 240 and the inner lining 610, and the first exhaust gap 251 communicates two adjacent sub-exhaust cavities.

[0114] In some embodiments, among the multiple sub-exhaust cavities, the sub-exhaust cavity facing the third vent 613 is the first sub-exhaust cavity 211.

[0115] Referring to Figure 9 , a plurality of stepped portions 612 are provided on the inner lining 610. The plurality of stepped portions 612 face the remaining sub-exhaust cavities except the first sub-exhaust cavity 211, and the plurality of stepped portions 612 increase in sequence along the gas discharge direction. The stepped portions 612 play a role in guiding the airflow and help to further reduce the exhaust noise.

[0116] For example, the exhaust cavity 210 includes a first sub-exhaust cavity 211 and a second sub-exhaust cavity 212. The steam discharged from the third vent 613 first enters the first sub-exhaust cavity 211. During the process of the steam flowing along the first exhaust gap 251 to the second sub-exhaust cavity 212, it flows in sequence along the stepped portions 612, reducing the exhaust noise.

[0117] In some embodiments, referring to Figure 4 and Figure 9 , a first mounting portion 611 is provided on the inner lining 610. The first mounting portion 611 extends towards the steam valve 200, and the first mounting portion 611 surrounds the third vent 613.

[0118] Referring to Figure 9 and Figure 14 , a second mounting portion 260 is provided on the steam valve 200. The second mounting portion 260 extends towards the inner lining 610, the second mounting portion 260 encloses the exhaust cavity 210, and the second mounting portion 260 abuts and seals against the first mounting portion 611.

[0119] The first mounting portion 611 and the second mounting portion 260 constitute the circumferential side wall of the exhaust cavity 210, and the first mounting portion 611 and the second mounting portion 260 are sealed at the butt joint, improving the sealing performance of the exhaust cavity 210.

[0120] In some embodiments, referring toFigure 9 A second sealing portion 640 is disposed between the first mounting portion 611 and the second mounting portion 260 . The second sealing portion 640 is a rubber sealing ring, which improves the sealing performance between the first mounting portion 611 and the second mounting portion 260 .

[0121] In some embodiments, reference Figure 14 One end of the partition 240 is connected to the second mounting portion 260 , and a second exhaust gap 252 is formed between the other end of the partition 240 and the second mounting portion 260 .

[0122] When the steam in the first sub-exhaust chamber 211 flows into the second sub-exhaust chamber 212, there are two flow paths, one is the first exhaust gap 251 at the bottom of the exhaust chamber 210, and the other is the second exhaust gap 252 on the side of the exhaust chamber 210. This arrangement improves the steam exhaust efficiency.

[0123] In some embodiments, the partition 240 is an arc-shaped curved structure, such as a wave-shaped structure, which buffers and guides the airflow, thereby helping to improve exhaust efficiency and reduce noise.

[0124] In some embodiments, reference Figure 9 The exhaust assembly 500 includes a third mounting portion 510 and a fourth mounting portion 520. The third mounting portion 510 is disposed on a side of the inner cover 630 facing the cooking cavity, and the fourth mounting portion 520 is disposed on a side of the inner cover 630 facing away from the cooking cavity.

[0126] The fourth mounting portion 520 and the inner cover 630 form a receiving chamber 550, in which the moving portion 530 is disposed, and the moving portion 530 is configured to open or close the exhaust passage 542. The receiving chamber 550 provides a moving space for the moving portion 530 and also limits the displacement of the moving portion 530.

[0127] The moving part 530 is a steel ball. When the steam is exhausted, the steel ball rises under the action of the steam to open the exhaust passage 542. When the steam is not exhausted, the steel ball falls back under the action of gravity and the exhaust passage 542 is closed by the steel ball.

[0128] The fourth mounting portion 520 is provided with a fourth vent 523 , and the fourth vent 523 connects the receiving chamber with the exhaust buffer chamber 615 .

[0129] When exhausting steam, the steam in the cooking cavity pushes the moving part 530 upward through the exhaust passage 542. The moving part 530 moves upward, the exhaust passage 542 is opened, and the steam enters the accommodation cavity 550 through the exhaust passage 542, and then flows into the exhaust buffer cavity 615 through the fourth vent 523.

[0130] The overall structure of the exhaust assembly 500 is compact, with a small volume and reliable exhaust.
