[0064] A cooking device, such as a rice cooker, includes a cooker body and a cooker lid. An inner pot is provided inside the cooker body, and a cooking cavity is formed inside the inner pot. The cooker lid is used to close or open the cooking cavity. A disclosed cooking device has a micro-pressure cooking function, which can improve the gelatinization degree of food materials (such as rice) under high-temperature conditions and shorten the cooking time, thereby improving the cooking effect.

[0065] Since the cooking cavity has a certain pressure during cooking, the above cooking device is prone to the phenomenon of overflowing the pot, and the noise is large during exhaust.

[0066] To solve this technical problem, referring to Figure 1 , the cooking device of the present disclosure includes a cooker body 10 and a cooker lid 20. A cooking cavity is formed inside the cooker body 10. The cooker lid 20 is rotatably connected to the cooker body 10, and the cooker lid 20 is configured to close or open the cooking cavity.

[0067] Reference Figure 8 and Figure 9 The lid 20 of the cooker includes an outer lid 620, an inner lid 630, and a lining 610. The outer lid 620 forms the outer wall of the lid 20 of the cooker. The inner lid 630 faces the cooking cavity. The lining 610 is disposed between the outer lid 620 and the inner lid 630, and the lining 610 serves as a mounting carrier for other components.

[0068] An exhaust buffer cavity 615 is formed between the inner lid 630 and the lining 610. A third vent 613 is provided on the lining 610, and the third vent 613 communicates with the exhaust buffer cavity 615.

[0069] There is a distance between the inner lid 630 and the lining 610. A ring-shaped sealing ring 614 is provided on one side of the lining 610 facing the inner lid 630. The sealing ring 614 abuts and seals against the inner lid 630, thereby enclosing the exhaust buffer cavity 615 between the lining 610 and the inner lid 630.

[0070] The lid 20 of the cooker includes an exhaust assembly 500. The exhaust assembly 500 is disposed on the inner lid 630, and the exhaust assembly 500 is configured to communicate or isolate the cooking cavity from the exhaust buffer cavity 615.

[0071] The lid 20 of the cooker includes a steam valve 200. The steam valve 200 is disposed on the lining 610. Figure 13 FIG. is a structural diagram of the steam valve 200 as viewed from the top side, Figure 14 FIG. is a structural diagram of the steam valve 200 as viewed from the bottom side, Figure 15 FIG. is a top view of the steam valve 200, Figure 16 FIG. is a cross-sectional view of the steam valve 200.

[0072] The steam valve 200 includes a second exhaust port 270 and an exhaust cavity 210. The second exhaust port 270 communicates with the outside atmosphere. A partition 240 is disposed in the exhaust cavity 210. The partition 240 divides the exhaust cavity 210 into a plurality of sub-exhaust cavities. One of the plurality of sub-exhaust cavities communicates with the second exhaust port 270, and the other communicates with the third vent 613. The gas flowing out from the third vent 613 is discharged through the plurality of sub-exhaust cavities and the second exhaust port 270 in sequence.

[0073] When the cooking cavity discharges steam outward, the exhaust assembly 500 communicates 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, and then enters the exhaust cavity 210 through the third vent 613. The steam flows through the plurality of sub-exhaust cavities in sequence, and finally is discharged from the second exhaust port 270.

[0074] The plurality of 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.

[0075] In some embodiments, the partition portion 240 divides the exhaust cavity 210 into two sub-exhaust cavities, denoted as a first sub-exhaust cavity 211 and a 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.

[0076] 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 connects the exhaust cavity 210 and the exhaust buffer cavity 615.

[0077] 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.

[0078] A first exhaust gap 251 is formed between the partition portion 240 and the inner lining 610, and the first exhaust gap 251 connects two adjacent sub-exhaust cavities.

[0079] 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.

[0080] 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.

[0081] 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 sequentially along the stepped portions 612 to reduce the exhaust noise.

[0082] 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 in a direction close to the steam valve 200, and the first mounting portion 611 surrounds the third vent 613.

[0083] Referring to Figure 9 and Figure 14A second mounting portion 260 is provided on the steam valve 200 . The second mounting portion 260 extends toward the direction close to the liner 610 . The second mounting portion 260 surrounds the exhaust cavity 210 . The second mounting portion 260 is sealed against the first mounting portion 611 .

[0084] The first mounting portion 611 and the second mounting portion 260 constitute a circumferential side wall of the exhaust cavity 210 . The first mounting portion 611 and the second mounting portion 260 are sealed at the butt joint to improve the sealing performance of the exhaust cavity 210 .

[0085] In some embodiments, reference Figure 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 .

[0086] 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 .

[0087] 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.

[0088] 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.

[0089] 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.

[0090] A third sealing portion 540 is disposed on the third mounting portion 510 . An exhaust passage 542 is formed in the third sealing portion 540 . The exhaust passage 542 is communicated with the cooking cavity. Figure 10 A structural diagram of the third sealing portion 540 .

[0091] A receiving cavity 550 is defined between the fourth installation part 520 and the inner cover 630. A moving part 530 is arranged in the receiving cavity 550 and is configured to open or close the exhaust passage 542. The receiving cavity 550 provides a moving space for the moving part 530 and also limits the displacement of the moving part 530.

[0092] The moving part 530 is a steel ball. When discharging steam, the steel ball rises under the action of the steam and opens the exhaust passage 542. When not discharging steam, the steel ball falls back under the action of gravity and closes the exhaust passage 542.

[0093] A fourth vent 523 is provided on the fourth installation part 520, and the fourth vent 523 communicates the cavity with the exhaust buffer cavity 615.

[0094] When discharging 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 receiving cavity 550 through the exhaust passage 542 and then flows into the exhaust buffer cavity 615 through the fourth vent 523.

[0095] The overall structure of the exhaust assembly 500 is compact, with a small volume and reliable exhaust.

[0096] In some embodiments, referring to Figure 11 and Figure 12 , a screw post 511 is provided on the third installation part 510, and a mounting hole 524 is provided on the fourth installation part 520. A connecting member (such as a screw) is fixedly connected to the inner cover 630 and the screw post 511 through the mounting hole 524 to fixedly install the exhaust assembly 500 on the inner cover 630.

[0097] In some embodiments, referring to Figure 11 , the fourth installation part 520 includes a flat part 521 and a protruding part 522. The flat part 521 is fixedly connected to the inner cover 630 through a connecting member such as a screw. A receiving cavity 550 is defined between the protruding part 522 and the inner cover 630, and the fourth vent 523 is provided on the side wall and / or the top wall of the protruding part 522. Multiple fourth vents 523 are provided to improve the exhaust efficiency.

[0098] In some embodiments, referring to Figure 10 , a receiving groove 541 is provided at the top of the third sealing part 540. When the moving part 530 falls back under the action of gravity, it falls into the receiving groove 541 and closes the exhaust passage 542.

[0099] In some embodiments, referring to Figure 13 , the steam valve 200 includes a second base part 230, and a mounting hole is provided on the second base part 230. The mounting hole is fixed to the inner liner 610 through a screw to fixedly install the steam valve 200.

[0100] In some embodiments, referring to Figure 16 , the third pipe connection part 220 communicates with one of the sub-exhaust cavities. For example, the third pipe connection part 220 communicates with the first sub-exhaust cavity 211.

[0101] When the cooking cavity is depressurized, the outside air enters the exhaust cavity 210 through the second exhaust port 270 of the steam valve 200. For example, it enters the first sub-exhaust cavity 211, then enters the third pipe connection part 220 through the first sub-exhaust cavity 211, enters the vacuum valve 100 through the first pipeline 400, and finally enters the cooking cavity to achieve depressurization. At this time, the exhaust cavity 210 is the second air flow channel 280.

[0102] In some embodiments, the cooking device has a vacuum negative pressure fresh-keeping function, which improves the preservation time of the ingredients in the cooking cavity and the flavor retention time. After the cooking device completes vacuum negative pressure fresh-keeping or micro-pressure cooking, when opening the lid, when the user presses the lid-opening button, it is necessary to trigger a pressure relief component, which is a physical pressure relief, and the lid-opening resistance is large, resulting in poor user experience.

[0103] To solve the above technical problems, referring to Figure 2 and Figure 3 , the cooking lid 20 includes a vacuum valve 100. Referring to Figure 5 , the vacuum valve 100 includes a first air flow channel 110, a first pipe connection part 120, and a second pipe connection part 130 that are connected.

[0106] The cooking lid 20 includes a vacuum pumping assembly 300. Referring to Figure 2 , the vacuum pumping assembly 300 is connected to the second pipe connection part 130 and is configured to pump the cooking cavity into a vacuum.

[0107] The cooking lid 20 includes a control valve 410. Referring to Figure 2 , the control valve 410 is arranged on the first pipeline 400, and the control valve 410 is configured to open or close the first pipeline 400. The pipeline between the control valve 410 and the steam valve 200 is the first pipeline 400A, and the pipeline between the control valve 410 and the vacuum valve 100 is the first pipeline 400B.

[0108] The cooking device includes a first working state. In the first working state, the cooking cavity is evacuated through the vacuum pumping assembly 300, and the cooking device can perform micro-pressure cooking.

[0109] In the first working state of the cooking device, the control valve 410 is closed to close the first pipeline 400, and the vacuum pumping assembly 300 is started to evacuate the cooking cavity. The gas in the cooking cavity is discharged from the cooking cavity through the first air flow channel 110 of the vacuum valve 100, the second pipe joint 130, and the vacuum pumping assembly 300 in sequence to complete the evacuation.

[0110] The cooking device includes a second working state. In the second working state, the cooking cavity is depressurized through the first pipeline 400 to open the cooking lid 20.

[0111] In the second working state of the cooking device, the vacuum pumping assembly 300 is closed, the control valve 410 is opened to open the first pipeline 400, and the outside air enters the cooking cavity through the second air flow channel 280 of the steam valve 200, the first pipeline 400, and the first air flow channel 110 of the vacuum valve 100 to depressurize the cooking cavity.

[0112] After the cooking of the cooking device of the present disclosure is completed or the user clicks to cancel the cooking, the control valve 410 is automatically opened to realize the automatic depressurization of the cooking cavity, reduce the opening resistance of the cooking lid 20, and improve the user experience.
