[0002] The pressure cooker can utilize the physical property that the boiling point of water is affected by air pressure. In the pressure cooker, water is evaporated to produce water vapor. Water vapor cannot diffuse in a sealed environment, thereby increasing the air pressure in the pot. Correspondingly, the boiling point of water will also increase, so that ingredients can be cooked at a higher temperature, speeding up the cooking time.

[0003] For some pressure cookers whose pot body is located in a shell, various valve bodies are installed on the pot cover. The valve bodies can connect the shell with the inner cavity of the pot body under certain conditions to release the pressure in the pot body, but this will cause the pressure in the shell to increase, and the cleaning of the inside of the shell also brings inconvenience.

[0056] The pressure cooker can utilize the physical property that the boiling point of water is affected by air pressure. In the pressure cooker, water is evaporated to produce water vapor. Water vapor cannot diffuse in a sealed environment, thereby increasing the air pressure in the pot. Correspondingly, the boiling point of water will also increase, so that ingredients can be cooked at a higher temperature, speeding up the cooking time.

[0057] For some pressure cookers whose pot body is located in a shell, various valve bodies are installed on the pot cover. The valve bodies can connect the shell with the inner cavity of the pot body under certain conditions to release the pressure in the pot body, but this will cause the pressure in the shell to increase, and the cleaning of the inside of the shell also brings inconvenience.

[0058] In order to solve the above problems, Figures 1 to 17 As shown, the utility model provides an embedded pressure cooker to avoid releasing steam into the shell.

[0059] In the illustrated embodiment, the pressure cooker is an embedded pressure cooker. Of course, in other embodiments, the pressure cooker can also be a desktop pressure cooker or other types of pressure cookers, and the utility model embodiment does not make specific restrictions here. For ease of description, the embedded pressure cooker is used as an example for description below.

[0060] like Figure 1 to Figure 2 As shown, specifically, the embedded pressure cooker includes a shell unit 10, a pot unit 20 and a pressure cover unit 30, wherein: the shell unit 10 includes a shell 11 and a mounting base 12 arranged in the shell 11, and the side of the shell 11 is provided with an opening 1111; the pot unit 20 is pullable and arranged in the shell 11 through the opening 1111; the pot unit 20 includes a pot body assembly 21 and a pot cover assembly 22, the pot cover assembly 22 is openably arranged in the pot body assembly 21 and forms a cooking cavity with the pot body assembly 21; the pressure cover unit 30 is movably arranged on the mounting base 12 and is located above the pot unit 20, and the pressure cover unit 30 has a locked state and an unlocked state, in the locked state, the pressure cover unit 30 is locked to the pot body assembly 21 and the pot cover assembly 22 is pressed to the pot body assembly 21, and in the unlocked state, the pressure cover unit 30 is disengaged from the pot body assembly 21 to allow the pot cover assembly 22 to be separated from the pot body assembly 21.

[0061] Before starting cooking, the pot cover assembly 22 is arranged on the pot body assembly 21, and the pot unit 20 is pushed into the housing 11 through the opening 1111 as a whole, and the cover pressing unit 30 is controlled to be closed and moved from the unlocked state to the locked state, so that the cover pressing unit 30 is locked to the pot body assembly 21 and the pot cover assembly 22 is pressed to the pot body assembly 21, so as to ensure the sealing of the pot unit 20 and prevent the internal pressure of the pot unit 20 from leaking, thereby ensuring the safety of the pressure cooker; after cooking is completed, the cover pressing unit 30 is controlled to move from the locked state to the unlocked state, so that the cover pressing unit 30 The pot unit 20 can be opened and separated from the pot body assembly 21, and the pot unit 20 can be pulled out of the shell 11 as a whole. Since the pot cover assembly 22 is pressed onto the pot body assembly 21 by the cover pressing unit 30 in the shell 11, there is no need to set a structure on the pot cover assembly 22 for snapping with the pot body assembly 21. After the pot unit 20 is pulled out of the shell 11 as a whole through the opening 1111, the pot cover assembly 22 can be directly removed from the pot body assembly 21, thereby avoiding the pot cover assembly 22 from occupying a large space after being turned up, and also will not affect the normal use of other equipment around the pressure cooker.

[0062] Furthermore, since the cover unit 30 is disposed in the shell 11, when the cover unit 30 is opened to separate it from the pot body assembly 21, it is sufficient to ensure that the pot unit 20 can be normally pulled out through the opening 1111. Therefore, the movable space of the cover unit 30 does not need to be very large, thereby reducing the overall volume of the pressure cooker.

[0063] like Figure 2 and Figure 4 As shown, a telescopic slide rail 114 is further provided in the housing 11, and the pot unit 20 is fixedly arranged on the telescopic slide rail 114, and the sliding direction of the telescopic slide rail 114 is arranged toward the opening 1111.

The base 213 is arranged on the telescopic slide rail 114, and the installation cavity in the base 213 is used to accommodate and support the pot seat 211 and the pot body 212, and drive the pot unit 20 to slide relative to the housing 11 as a whole. In addition, the installation cavity of the base 213 can facilitate the user to position the pot seat 211 when installing the pot seat 211, and the pot seat 211 can facilitate the user to align the pot body 212 when installing the pot body 212. Since the positions of the pot seat 211 and the base 213 are relatively fixed, the pot unit 20 and the pressure cover unit 30 can be aligned by only pushing the base 213 into the housing 11 through the telescopic slide rail 114, which is convenient for pulling and pulling, and avoids repeated alignment of the pot unit 20.

[0065] Furthermore, the mounting base 12 is provided with a coupler female end 121, and the base 213 is provided with a coupler male end 2131. When the base 213 is pushed into the housing 11 through the telescopic slide rail 114, the coupler male end 2131 is plugged and matched with the coupler female end 121 to supply power to the pot unit 20. When the base 213 is pulled out of the housing 11, the coupler male end 2131 is disconnected from the coupler female end 121. In addition, handles are provided on both sides of the pot body 212 and the pot cover assembly 22, so that the user can take or place the pot body 212 and the pot cover assembly 22.

The user can control the cover assembly 31 to rotate relative to the pot body assembly 21 through the unlocking assembly 32 outside the housing 11, so that the cover unit 30 can switch between a locked state and an unlocked state, and the operation is simple and convenient. In the locked state, the cover assembly 31 is locked with the pot body assembly 21, and the pot cover assembly 22 is pressed against the pot body assembly 21; in the unlocked state, the cover assembly 31 can be opened and separated from the pot body assembly 21, so that the pot unit 20 can be pulled out of the housing 11.

[0067] like Figures 2 to 3 As shown, specifically, the edge of the pot seat 211 is provided with a plurality of flanges 2111, and the plurality of flanges 2111 are arranged circumferentially along the edge of the pot seat 211 at intervals; the pressure cover assembly 31 includes a pressure cover 311 and a bracket 312 fixed to the pressure cover 311, the unlocking assembly 32 is movably arranged on the bracket 312, the pressure cover 311 includes a crimping portion 3111 and a plurality of buckles 3112 arranged on the crimping portion 3111, so that in the locked state, the buckles 3112 are buckled on the flanges 2111 to crimp the crimping portion 3111 to the pot cover assembly 22. The bracket 312 is fixed on the crimping portion 3111. The buckles 3112 and the flanges 2111 have a simple structure, and can ensure the reliability of the connection between the pressure cover 311 and the pot seat 211 in the locked state, thereby ensuring the sealing and use safety of the pot unit 20.

[0068] It can be understood that along the circumference of the pot seat 211 and the pressure cover 311, the distance between two adjacent flanges 2111 needs to be greater than the length of the buckle 3112, and the distance between two adjacent buckles 3112 needs to be greater than the length of the flange 2111, and the flange 2111 and the buckle 3112 are arranged one by one. In the unlocked state, the flange 2111 and the buckle 3112 are arranged in a staggered manner so that the pressure cover 311 can be stably covered on the pot seat 211, or the pressure cover 311 can be separated from the pot seat 211; when the pressure cover assembly 31 is controlled to rotate relative to the pot body assembly 21 to the locked state, the flange 2111 and the buckle 3112 are arranged correspondingly, the pressure cover 311 cannot be separated from the pot seat 211, and the pot cover assembly 22 is pressed tightly against the pot body 212.

[0069] like Figure 1 , Figure 2 and Fig. 9 As shown, in the illustrated embodiment, the cover pressing unit 30 further includes a flip cover assembly 33, the cover pressing assembly 31 is rotatably arranged on the flip cover assembly 33, and one end of the flip cover assembly 33 is rotatably connected to the mounting seat 12.

Alternatively, one end of the flip cover 332 is rotatably connected to the mounting seat 12, the cover pressing unit 31 is rotatably arranged on the other end of the flip cover 332, and the flip cover shield 331 is covered on the flip cover 332. In the unlocked state, the flip cover 332 and the flip cover shield 331 can be controlled to rotate and open relative to the mounting seat 12 along the -X direction, so that the cover pressing unit 311 is separated from the pot seat 211, and the pot unit 20 can be pulled out of the housing 11. After the pot unit 20 is pushed into the housing 11, the flip cover 332 and the flip cover shield 331 can be controlled to rotate and close relative to the mounting seat 12 along the +X direction, so that the pressing cover 311 covers the pot seat 211. The flip cover shield 331 can prevent oil stains or dust in the housing 11 from entering the pressing cover unit 30. In addition, the opening and closing structure of the pressing cover unit 30 is simple and does not occupy too much space in the housing 11.

[0070] like Figure 3 and Fig.10As shown, the unlocking assembly 32 includes a horizontal adjustment member 321 and a lever 322. The horizontal adjustment member 321 is rotatably arranged on the bracket 312 along the horizontal direction, and the lever 322 is arranged on the horizontal adjustment member 321. Since the horizontal adjustment member 321 can rotate relative to the bracket 312, and the bracket 312 is fixed on the crimping portion 3111, when the user controls the horizontal adjustment member 321 to translate horizontally along the +Y direction through the lever 322 outside the housing 11, the horizontal adjustment member 321 can drive the crimping portion 3111 of the pressure cover 311 to rotate relative to the pot seat 211 to the unlocking state, and the horizontal adjustment member 321 will rotate relative to the bracket 312; on the contrary, when the user controls the horizontal adjustment member 321 to translate horizontally along the -Y direction through the lever 322, the horizontal adjustment member 321 can drive the crimping portion 3111 of the pressure cover 311 to rotate relative to the pot seat 211 to the locking state.

[0071] The unlocking assembly 32 further includes a longitudinal adjustment member 323, which is rotatably disposed on the horizontal adjustment member 321, and a lever 322 is disposed on the longitudinal adjustment member 323 to drive the cover pressing unit 30 to rotate relative to the mounting seat 12. Since the cover pressing unit 30 can rotate relative to the mounting seat 12 along the ±X direction, and the longitudinal adjustment member 323 can rotate relative to the horizontal adjustment member 321, in the unlocking state, when the user controls the longitudinal adjustment member 323 to move along the +Z direction outside the housing 11 through the lever 322, the longitudinal adjustment member 323 can drive the cover pressing unit 30 to rotate and open along the +X direction relative to the mounting seat 12, and the longitudinal adjustment member 323 will rotate relative to the horizontal adjustment member 321; on the contrary, when the user controls the longitudinal adjustment member 323 to move along the -Z direction through the lever 322, the longitudinal adjustment member 323 can drive the cover pressing unit 30 to rotate and close along the -X direction relative to the mounting seat 12.

[0072] Furthermore, the longitudinal adjustment member 323 is a sleeve, and the lever 322 can be movably passed through the sleeve, so that when the lever 322 is adjusted, the length of the portion of the lever 322 exposed from the housing 11 remains unchanged, and the lever 322 is prevented from protruding excessively from the housing 11, which is convenient for user operation.

[0073] In another embodiment, the cover unit 30 can be raised and lowered relative to the mounting base 12. When the cover unit 30 is raised, the cover 311 is separated from the pot seat 211. When the cover unit 30 is lowered, the cover 311 covers the pot seat 211. The unlocking assembly 32 includes a horizontal adjustment member 321 and a lever 322. The user can control the horizontal adjustment member 321 to move horizontally in the ±Y direction outside the housing 11 through the lever 322 to drive the cover 311 to switch between the locked state and the unlocked state relative to the pot seat 211. The user can also control the horizontal adjustment member 321 to move in the ±Z direction outside the housing 11 through the lever 322 to drive the cover unit 30 to rise and fall relative to the mounting base 12.

[0074] like Figure 1 and Figure 5 As shown, the housing 11 includes a box body 111, a door body 112 and a control panel 113. The opening 1111 is arranged at one side of the box body 111. The control panel 113 and the door body 112 are both arranged at the opening 1111 of the box body 111. The door body 112 is arranged on the box body 111 in an openable and closable manner and is arranged corresponding to the pot unit 20. The control panel 113 is arranged above the door body 112 and is arranged corresponding to the pressure cover unit 30. The door body 112 can be fixed to the base 213, and when the door body 112 is pulled outward, the pot unit 20 can be pulled out of the box body 111 from the opening 1111. During the cooking process, the box body 111 and the door panel can play a protective role when the pot unit 20 accidentally sprays, thereby improving the safety of the pressure cooker. The user can control the operation of the pressure cooker through the control panel 113. Placing the control panel 113 above the door body 112 can prevent the control panel 113 from affecting the normal pulling out of the pot unit 20. At the same time, the control panel 113 and the cover unit 30 are arranged correspondingly, so that the user can control the movement of the cover unit 30 at the control panel 113.

[0075] like Figures 5 to 7 As shown, in the illustrated embodiment, a slideway 1131 is provided on the control panel 113, and the lever 322 can movably pass through the slideway 1131. The slideway 1131 is used to limit the travel of the lever 322, so that the user can control the lever 322 and the operation is convenient.

[0076] Specifically, the control panel 113 is provided with a horizontal slide 11311 and a longitudinal slide 11312 connected to one end of the horizontal slide 11311; when the lever 322 is in the horizontal slide 11311, the pressure cover assembly 31 is driven relative to the pot body assembly 21 along the longitudinal slide 11312; Fig.10 When the lever 322 is in the longitudinal slideway 11312, the cover pressing unit 30 is in the unlocked state, and the lever 322 drives the cover pressing unit 30 to rotate relative to the mounting seat 12 along the Figure 1 to Figure 2 The ±X direction rotation is shown. This prevents the user from controlling the lever 322 to move too much, which may cause damage to the lever 322, the horizontal adjustment member 321, the longitudinal adjustment member 323 or the cover pressing unit 30, and at the same time facilitates user operation.

[0077] In other embodiments, an opening may be provided on the control panel 113 , the range of the opening being greater than or equal to the range of motion of the lever 322 , the lever 322 extending out of the box 111 through the opening, and the user may control the lever 322 to move in the opening to drive the cover unit 30 to move.

[0078] like Figures 9 to 11As shown, the pressure cover 311 also includes a pressure plate 3115 fixed to the flip cover assembly 33, and the pressure connection portion 3111 is set in an annular shape. The annular pressure connection portion 3111 is set on the outer periphery of the pressure plate 3115 and can rotate relative to the pressure plate 3115. When the pressure connection portion 3111 is controlled to rotate relative to the pot body assembly 21, the pressure plate 3115 is fixed relative to the pot body assembly 21. The bracket 312 includes a frame body 3121 and a trigger portion 3122 protruding from the frame body 3121; a micro switch 3114 is provided on the pressure plate 3115. When the pressure cover unit 30 is in a locked state, the trigger portion 3122 touches the micro switch 3114. When the trigger portion 3122 touches the micro switch 3114, the micro switch 3114 is energized, and the internal program of the pressure cooker recognizes the locking signal and connects the power supply line for heating the pot unit 20. That is to say, the pressure cooker can start working only when the cover unit 30 is in a locked state, that is, the internal pressure of the pot unit 20 will not leak, thereby improving the safety of the pressure cooker.

[0079] like Figures 9 and 10 As shown, since the pressure in the steam chamber is very high during the operation of the embedded device, the pot cover assembly 22 includes a pot cover 221 and a valve assembly arranged on the pot cover 221, so as to release the pressure in the steam chamber under certain conditions through the valve assembly.

[0080] like Figures 10 to 12 As shown, in order to prevent the user from opening the cover unit 30 and the pot cover assembly 22 when the pressure in the steam chamber is high, the bracket 312 includes a stopper 3123 protruding from the bracket body 3121, and the valve assembly includes a stopper valve 222, the stopper valve 222 has a first path a for lifting and floating, and the stopper 3123 has a second path b for horizontal rotation, and the first path a intersects with the second path b. When the pressure in the steam chamber is high, the stopper valve 222 rises along the first path a. At this time, since the first path a intersects with the second path b, the stopper valve 222 blocks the stopper 3123, so that the stopper 3123 cannot move along the second path b, and the unlocking assembly 32 cannot move along the +Y direction, so that the cover unit 30 cannot move to the unlocked state, thereby improving the safety of the pressure cooker. When the pressure in the steam chamber drops, the stop valve 222 can drop along the first path a to a fully dropped state. At this time, the stop valve 222 will not block the stop portion 3123, and the stop portion 3123 can move along the second path b, thereby allowing the cover unit 30 to move from a locked state to an unlocked state.

[0081] like Fig.10 and Fig.12As shown, since the check valve 222 may not be able to reset to the fully lowered state after the pressure in the steam chamber drops due to factors such as jamming after rising, the pressure cooker further includes a first driving mechanism 40, which is disposed on the pressing plate 3115 of the cover pressing unit 30, and includes a movable first movable member 41, the first movable member 41 having a third path c, and the third path c intersects with the first path a so that the first movable member 41 can push the check valve 222. When the pressure in the steam chamber drops and the check valve 222 is not reset, the first movable member 41 can move along the third path c and approach the check valve 222, and push the check valve 222 to reset, so that the cover pressing unit 30 can move normally to the unlocked state.

[0082] The first drive mechanism 40 moves together with the cover unit 30. When the cover unit 30 is opened, the first drive mechanism 40 is completely separated from the check valve 222. When the cover unit 30 is closed, the first drive mechanism 40 is arranged corresponding to the check valve 222, and the first movable member 41 is aligned with the check valve 222. Alternatively, the first drive mechanism 40 can also be arranged on the pot cover 221. When the pot unit 20 is pulled out of the housing 11, the first drive mechanism 40 moves together with the pot unit 20.

[0083] like Fig.14 As shown, the first movable member 41 has a first inclined surface 411 disposed toward the check valve 222, and the first inclined surface 411 extends obliquely upward from the bottom wall of the first movable member 41 toward the side wall of the first movable member 41. The first inclined surface 411 abuts against the check valve 222 and plays a guiding role. When the first movable member 41 gradually approaches the check valve 222 along the third path c, the check valve 222 can be gradually pushed downward to reset the check valve 222.

[0084] Specifically, the first inclined surface 411 is provided with a starting point and an end point spaced apart from the starting point, and the starting point is located on the upper side of the end point. When the stop valve 222 contacts the first inclined surface 411 at the starting point, the stop valve 222 is in a state of starting to descend, and when the stop valve 222 contacts the end point of the first inclined surface 411, the stop valve 222 is in a state of complete descent. In other words, along the lifting direction of the stop valve 222, the size of the first inclined surface 411 needs to be greater than or equal to the maximum lifting distance of the stop valve 222 to ensure that the first inclined surface 411 of the first movable member 41 can contact the stop valve 222 and can push the stop valve 222 to a state of complete descent. It can be understood that when the stop valve 222 rises to different heights, the position of the starting point of the first inclined surface 411 is also different.

[0085] like Fig.10 and Fig.14As shown, the first driving mechanism 40 also includes a first push rod 42 and a push rod mounting seat 43 fixed on the pressure plate 3115 of the pressure cover unit 30, a compressible first elastic member 44 is arranged in the push rod mounting seat 43, the first push rod 42 passes through the first elastic member 44 and is movably arranged on the push rod mounting seat 43, and the first movable member 41 is arranged at one end of the first push rod 42. The push rod mounting seat 43 is used to support the push rod and limit the movement path of the push rod, so that the first push rod 42 and the first movable member 41 can only move along the third path c. The user can control the push rod and the first movable member 41 to move along the third path c to the side close to the check valve 222, the first elastic member 44 is compressed, and the first movable member 41 pushes the check valve 222 to a fully descended state, and the first movable member 41 and the push rod can be reset under the elastic force of the first elastic member 44, so that manual reset is not required, which is convenient for user operation.

[0086] like Figure 1 and Figure 5 As shown, in the illustrated embodiment, a gap 115 is provided between the control panel 113 and the door body 112, and the other end of the first push rod 42 is at least partially located in the gap 115. The user can push the push rod through the gap 115, so that the push rod and the first movable member 41 move along the third path c toward the side close to the check valve 222, which is easy to operate and the structure of the housing 11 is simple.

[0087] In another embodiment, the control panel 113 may be provided with an avoidance hole, and the other end of the first push rod 42 may be at least partially located in the avoidance hole, and the user pushes the push rod through the avoidance hole. Of course, in other embodiments, other structures that can drive the first movable member 41 to move along the third path c may be used, such as a solenoid valve, an electric push rod, a gear rack structure, etc., and the embodiment of the utility model is not specifically limited here.

[0088] like Fig.10 and Fig.12As shown, the valve assembly also includes a pressure limiting valve assembly 224, and the pressure cooker also includes a pressure limiting valve driving assembly 70. The pressure limiting valve driving assembly 70 is arranged on the pressure plate 3115 of the gland assembly 31. In the locked state, the pressure limiting valve driving assembly 70 is used to drive the pressure limiting valve assembly 224 to open and close. During operation, when the pressure in the steam chamber is high, the pressure limiting valve driving assembly 70 can drive the pressure limiting valve assembly 224 to open, release part of the steam in the pot unit 20, so as to reduce the pressure in the steam chamber, avoid explosion due to excessive pressure, and reduce safety hazards; when the pressure in the steam chamber is reduced to normal pressure, the pressure limiting valve driving assembly 70 drives the pressure limiting valve assembly 224 to close, so as to ensure the normal operation of the pressure cooker. Since the pressure limiting valve assembly 224 is arranged on the pot cover 221 and the pressure limiting valve driving assembly 70 is arranged on the pressure cover unit 30, when the pot unit 20 is pulled out of the shell 11, the pressure limiting valve assembly 224 will be pulled out of the shell 11 together with the pot unit 20, while the pressure limiting valve driving assembly 70 remains in the shell 11, thereby avoiding the pressure limiting valve driving assembly 70 being arranged on the pot cover 221, which will cause the structure of the pot cover 221 to be complicated, thereby simplifying the structure of the pot cover 221 and facilitating assembly. At the same time, it also avoids the pressure limiting valve driving assembly 70 affecting the user's taking or placing of the pot cover 221, thereby improving the user experience.

[0089] like Fig.15 As shown, the pressure limiting valve assembly 224 includes a pressure limiting valve seat 2241, a valve body 2242 and a steam exhaust pipe 2243. The steam exhaust pipe 2243 is arranged on the pressure limiting valve seat 2241. The steam exhaust pipe 2243 is connected with the cooking chamber and the outside. The valve body 2242 is movably arranged on the pressure limiting valve seat 2241 for opening and closing the steam outlet of the steam exhaust pipe 2243. The pressure limiting valve driving assembly 70 can drive the valve body 2242 to move. The valve seat is used to limit the range of movement of the valve body 2242, so that when the pressure limiting valve driving assembly 70 drives the valve body 2242 to move relative to the pressure limiting valve seat 2241, the valve body 2242 can accurately open or close the steam outlet of the steam exhaust pipe 2243, so as to avoid the steam in the steam chamber from leaking from the steam exhaust pipe 2243 during the working process.

[0090] like Fig.15 As shown, in the illustrated embodiment, a lifting mechanism 2244 is provided between the valve body 2242 and the pressure limiting valve seat 2241, and the valve body 2242 is lifted and lowered relative to the pressure limiting valve seat 2241 by the lifting mechanism 2244. When the pressure in the steam chamber is high, the valve body 2242 can be lifted and lowered relative to the pressure limiting valve seat 2241 by the lifting mechanism 2244 under the drive of the pressure limiting valve drive assembly 70 to open the steam outlet of the exhaust pipe 2243; when the pressure in the steam chamber is reduced to normal pressure, the valve body 2242 can be lowered relative to the pressure limiting valve seat 2241 by the lifting mechanism 2244 to close the steam outlet of the exhaust pipe 2243.

[0091] Specifically, the lifting mechanism 2244 includes a vertical rib 22441 and a guide step 22442 matched with the vertical rib 22441, the guide surface of the guide step 22442 is an inclined surface, one of the vertical rib 22441 and the guide step 22442 is arranged on the inner wall of the pressure limiting valve seat 2241, and the other is arranged on the outer wall of the valve body 2242. The pressure limiting valve driving assembly 70 can drive the valve body 2242 to rotate relative to the pressure limiting valve seat 2241, the vertical rib 22441 cooperates with the inclined surface of the guide step 22442, and during the rotation of the valve body 2242, under the pushing action of the vertical rib 22441, the valve body 2242 will be lifted and lowered relative to the pressure limiting valve seat 2241. When the guide step 22442 is provided on the outer wall of the valve body 2242 and the vertical rib 22441 is provided on the inner wall of the pressure limiting valve seat 2241, the vertical rib 22441 cooperates with the highest point of the inclined surface of the guide step 22442, and the pressure limiting valve assembly 224 is in a closed state; the vertical rib 22441 cooperates with the lowest point of the inclined surface of the guide step 22442, and the pressure limiting valve assembly 224 is in an open state. There are multiple vertical ribs 22441 and guide steps 22442, and they are arranged one by one. Multiple vertical ribs 22441 are evenly spaced along the circumference of the pressure limiting valve seat 2241 to ensure the stability of the valve body 2242 during the lifting process.

[0092] like Fig.15 As shown, the valve body 2242 includes a valve sleeve 22421 and a plugging portion 22422. A hollow hole is provided on the top of the valve sleeve 22421. The plugging portion 22422 is fixed to the inner top wall of the valve sleeve 22421. The exhaust port of the exhaust pipe 2243 is located in the valve sleeve 22421 and cooperates with the plugging portion 22422. When the valve body 2242 rises relative to the pressure limiting valve seat 2241, the plugging portion 22422 is separated from the exhaust pipe 2243, and the steam in the cooking cavity can enter the valve sleeve 22421 through the exhaust port of the exhaust pipe 2243 and be discharged to the outside through the hollow hole of the valve sleeve 22421; when the valve body 2242 falls relative to the pressure limiting valve seat 2241, the plugging portion 22422 blocks the exhaust port of the exhaust pipe 2243, so that the steam in the cooking cavity cannot be discharged through the pressure limiting valve assembly 224.

[0093] Among them, the plugging part 22422 can be in a ball-head shape. When the plugging part 22422 blocks the exhaust port of the exhaust pipe 2243, the ball-head plugging part 22422 can completely fit with the edge of the exhaust port to ensure sealing. And because the valve body 2242 needs to rotate relative to the pressure limiting valve and the exhaust pipe 2243, the ball-head plugging part 22422 has no requirements for the installation direction, which is convenient for assembly. Alternatively, the plugging part 22422 can also be in a columnar structure that matches the shape of the exhaust port of the exhaust pipe 2243. When the plugging part 22422 blocks the exhaust port of the exhaust pipe 2243, the outer peripheral wall of the columnar plug fits with the inner peripheral wall of the exhaust port.

[0094] In other embodiments, the lifting mechanism 2244 may also be configured as a threaded matching structure or other structure that can drive the valve body 2242 to lift relative to the pressure limiting valve seat 2241 to open or close the steam outlet. Alternatively, the pressure limiting valve drive assembly 70 may also drive the valve body 2242 to translate in the horizontal direction relative to the pressure limiting valve seat 2241 to open or close the steam outlet.

[0095] like Fig.10 As shown, the pressure limiting valve drive assembly 70 includes a driving member 71 and a second push rod 72, and one end of the second push rod 72 is arranged at the driving end of the driving member 71; a paddle 22423 is provided on the outer wall of the valve body 2242, and in the locked state, the other end of the push rod is arranged corresponding to the paddle 22423 and can drive the paddle 22423 to rotate. When the pressure in the steam chamber is high, the driving member 71 can drive the second push rod 72 to extend toward the paddle 22423 and push the paddle 22423, so that the valve body 2242 rotates relative to the pressure limiting valve seat 2241, and the valve body 2242 rises under the action of the vertical rib 22441 and the guide step 22442 and opens the exhaust port of the exhaust pipe 2243; when the pressure in the steam chamber is reduced to normal pressure, the driving member 71 can drive the second push rod 72 to retract, the valve body 2242 descends under the action of its own gravity, and rotates and resets relative to the pressure limiting valve seat 2241 under the cooperation of the vertical rib 22441 and the guide step 22442, and the exhaust port of the exhaust pipe 2243 is closed. The structure of the pressure limiting valve driving assembly 70 is simple, and the second push rod 72 drives the valve body 2242 to rotate by moving in the horizontal direction, which can also reduce the size of the pressure limiting valve driving assembly 70 along the height direction of the pressure cooker, thereby avoiding occupying too much space on the gland unit 30.

[0096] The pressure limiting valve driving assembly 70 moves together with the gland unit 30. When the gland unit 30 is opened, the pressure limiting valve driving assembly 70 is completely separated from the pressure limiting valve assembly 224. When the gland unit 30 is closed, the pressure limiting valve driving assembly 70 is arranged correspondingly to the pressure limiting valve assembly 224, and the second push rod 72 is aligned with the paddle 22423. Alternatively, the pressure limiting valve driving assembly 70 can also be arranged on the pot cover 221. When the pot unit 20 is pulled out of the housing 11, the pressure limiting valve driving assembly 70 moves together with the pot unit 20.

[0097] In the illustrated embodiment, the driving member 71 is a solenoid valve. When the solenoid valve is powered on, the second push rod 72 extends toward the paddle 22423; when the solenoid valve is powered off, the second push rod 72 retracts. Of course, in other embodiments, the pressure-limiting valve driving assembly 70 can also be configured as an electric push rod, a gear rack structure, or other structure capable of pushing the paddle 22423; or, the pressure-limiting valve driving assembly 70 can also be configured as a structure capable of directly driving the valve body 2242 to rotate relative to the pressure-limiting valve seat 2241, and the embodiment of the utility model does not make specific restrictions here.

[0098] like Fig.15 As shown, since the steam inlet end of the exhaust pipe 2243 is connected to the steam chamber, in order to prevent the steam in the steam chamber from being blocked by the oil stains in the steam chamber and the steam inlet end of the exhaust pipe 2243, resulting in the steam in the steam chamber being unable to be discharged from the pressure limiting valve assembly 224 in time, the pressure limiting valve assembly 224 also includes an anti-blocking head 2245, which is sleeved on the steam inlet end of the exhaust pipe 2243 and is provided with a plurality of first through holes 22451. The steam in the cooking chamber can first enter the anti-blocking head 2245 through the plurality of first through holes 22451, and then enter the exhaust pipe 2243 through the steam inlet end of the exhaust pipe 2243. Even if some of the first through holes 22451 are blocked by oil stains, the steam in the cooking chamber can be discharged through the unblocked first through holes 22451, thereby avoiding the potential safety hazard caused by the inability to discharge the steam in the cooking chamber in time. The anti-blocking head 2245 includes a side wall and a bottom wall connected to an end of the side wall away from the pot cover 221 , and a plurality of first through holes 22451 are provided on the side wall and the bottom wall of the anti-blocking head 2245 .

[0099] like Fig.10 and Fig.15 As shown, the pressure limiting valve assembly 224 is provided with a first magnetic member 2246, and the pot cover 221 is provided with a Hall element 2212 or a reed switch that can sense the first magnetic member 2246. The Hall element 2212 and the reed switch on the pot cover 221 can both identify the magnet signal of the first magnetic member 2246 to detect whether the pressure limiting valve assembly 224 is installed. After the pressure cooker is powered on, if the Hall element 2212 or the reed switch identifies the magnet signal, it means that the pressure limiting valve assembly 224 is installed in place; if the Hall element 2212 or the reed switch does not identify the magnet signal, it means that the pressure limiting valve assembly 224 is not installed or the pressure limiting valve assembly 224 is not installed in place. At this time, the pressure cooker can alarm and prompt on the control panel 113 that the pressure limiting valve assembly 224 is not installed, so as to prevent the pressure cooker from starting to work when the pressure limiting valve assembly 224 is not installed, thereby improving the safety of use.

[0100] Specifically, when the pot cover 221 is provided with a Hall element 2212, since the first magnetic member 2246 is close to the Hall element 2212, the Hall element 2212 can detect a pulse signal, and therefore, it can be determined whether the pressure limiting valve assembly 224 is installed according to whether the Hall element 2212 detects a pulse signal. When the pot cover 221 is provided with a reed switch, since the first magnetic member 2246 is close to the reed switch, the two magnetic reeds in the reed switch will be in contact and connected, and therefore, it can be determined whether the pressure limiting valve assembly 224 is installed according to whether the reed switch is turned on.

[0101] like Fig.10 and Fig.12As shown, the valve assembly further includes a juice collecting valve assembly 223, the pot cover 221 is provided with a juice collecting hole 2211, the juice collecting valve assembly 223 is arranged on the pot cover 221 for opening and closing the juice collecting hole 2211, the juice collecting valve assembly 223 includes a valve stem 2231 and a sealing plate 2233 fixed to one end of the valve stem 2231, the valve stem 2231 is escalably arranged on the pot cover 221, and the sealing plate 2233 is located in the cooking cavity for opening and closing the juice collecting hole 2211. The pressure cooker further includes a second driving mechanism 50, the second driving mechanism 50 is arranged on the pressing plate 3115 of the pressing cover unit 30, the second driving mechanism 50 includes a driving assembly 51 and a second movable member 52 arranged on the driving assembly 51, and the driving assembly 51 drives the second movable member 52 to move telescopically to drive the valve stem 2231 to rise and fall. When the sealing plate 2233 closes the juice collecting hole 2211, the pressure and temperature in the cooking cavity can be guaranteed; when the juice of the food needs to be collected, the driving assembly 51 drives the second movable member 52 to extend toward the juice collecting valve assembly 223, so that the valve stem 2231 and the sealing plate 2233 are lowered, and the sealing plate 2233 opens the juice collecting hole 2211, and the steam in the cooking cavity can be discharged to the outside through the juice collecting hole 2211 to shrink the soup; after the juice collection is completed, the driving assembly 51 drives the second movable member 52 to retract and return to its original position, so that the valve stem 2231 and the sealing plate 2233 are raised, and the sealing plate 2233 closes the juice collecting hole 2211 again. The valve stem 2231 and the sealing plate 2233 are driven to rise and fall by the second driving mechanism 50 to open and close the juice collecting hole 2211, which is easy to operate, and can prevent the user from being scalded by steam overflow when manually controlling the juice collecting valve assembly 223, thereby reducing safety hazards.

[0102] like Figure 16 to Figure 17 As shown, in the illustrated embodiment, the driving assembly 51 includes a motor 511, a gear 512 and a driving rod 513, one end of the driving rod 513 is provided with a rack 5131, the gear 512 is provided at the output end of the motor 511 and meshes with the rack 5131, and the second movable member 52 is provided at the other end of the driving rod 513. The motor 511 can drive the gear 512 to rotate, and since the gear 512 meshes with the rack 5131 of the driving rod 513, the driving rod 513 can slide relative to the gear 512, and the second movable member 52 slides together with the driving rod 513 to approach or move away from the juice collection valve assembly 223. The driving assembly 51 has a simple structure and is easy to assemble.

[0103] Specifically, the driving rod 513 includes a rod body 5132 and an adapter 5133 connected to the rod body 5132. The adapter 5133 is a waist-shaped hole, and a rack 5131 is provided on the inner wall of the long side of the adapter 5133. The gear 512 is located in the waist-shaped hole and meshes with the rack 5131. The driving rod 513 slides relative to the gear 512 along the extension direction of the long side of the waist-shaped hole through the waist-shaped hole of the adapter 5133. The waist-shaped hole can limit the range of motion of the driving rod 513, ensuring that the gear 512 and the rack 5131 can always mesh, and preventing the driving rod 513 from deviating or moving too much to cause the gear 512 and the rack 5131 to lose teeth.

[0104] Furthermore, the second driving mechanism 50 also includes a seat body 53, which is arranged on the pressure plate 3115. The seat body 53 includes an open assembly groove 531 and a cover 532. The gear 512 and the rack 5131 are both located in the assembly groove 531. The rack 5131 can move along the assembly groove 531, and the cover 532 is covered in the assembly groove 531. The assembly groove 531 can also limit the range of motion of the adapter 5133, ensuring that the drive rod 513 and the second movable member 52 always slide along the same straight line, and the movement line will not be too large. The cover 532 can prevent oil stains or dust in the housing 11 from entering the assembly groove 531 and affecting the normal movement of the gear 512 and the rack 5131.

[0105] In another embodiment, the driving assembly 51 includes a motor 511, a screw and a slider, the screw is provided at the output end of the motor 511, the slider is provided with a threaded hole and is threadedly matched with the screw, and the second movable member 52 is connected to the slider. The motor 511 can drive the screw to rotate, so that the slider can slide relative to the screw, and the second movable member 52 slides with the slider to approach or move away from the juice collection valve assembly 223.

[0106] Of course, in other embodiments, the driving component 51 can also be configured as a solenoid valve, an electric push rod, or other structures that can drive the second movable member 52 to move in a straight line, and the embodiment of the utility model does not make specific limitations here.

[0107] like Fig.12 , Fig.13 and Fig.16As shown, in the illustrated embodiment, the juice collecting valve assembly 223 further includes a second elastic member 2232 and a baffle 22311 disposed on the valve stem 2231, and the second elastic member 2232 is located between the pot cover 221 and the baffle 22311 to allow the valve stem 2231 to drive the sealing plate 2233 to move up and down. When the second movable member 52 slides along the +W direction and approaches the valve stem 2231, the valve stem 2231 is pushed downward, the sealing plate 2233 is separated from the pot cover 221, the juice collecting hole 2211 is opened, and the second elastic member 2232 is compressed; when the second movable member 52 slides along the -W direction and away from the valve stem 2231, it is separated from the valve stem 2231, and the valve stem 2231 and the sealing plate 2233 slide upward and reset under the elastic force of the second elastic member 2232, so that the sealing plate 2233 fits with the pot cover 221, and the juice collecting hole 2211 is closed. The blocking piece 22311 is used to limit the second elastic member 2232 and can also limit the travel of the valve stem 2231 to prevent the valve stem 2231 from being completely pushed into the cooking cavity and unable to return to its original position.

[0108] Among them, the ±W direction is perpendicular to the direction of the juice collecting valve lifting and lowering, that is, it moves in the horizontal direction to reduce the size of the second driving mechanism 50 in the height direction of the pressure cooker and avoid occupying too much space on the cover pressing unit 30. The second movable member 52 has a second inclined surface 521 arranged toward the valve stem 2231, and the second inclined surface 521 extends upward from the bottom wall of the second movable member 52 toward the side wall of the second movable member 52. The second inclined surface 521 can abut against the end of the valve stem 2231 away from the sealing plate 2233 and play a guiding role. When the second movable member 52 gradually approaches the valve stem 2231 along the +W direction, the valve stem 2231 and the sealing plate 2233 can be gradually pushed downward, so that the distance between the sealing plate 2233 and the pot cover 221 gradually increases. It can be understood that the larger the distance between the sealing plate 2233 and the pot cover 221, the faster the rate at which the steam in the cooking cavity is discharged to the outside through the juice collecting hole 2211, and the faster the juice collecting rate. Therefore, the extension distance of the second movable member 52 along the +W direction can be controlled by the driving assembly 51 as needed to adjust the juice collection rate.

[0109] In another embodiment, the driving rod 513 and the second movable part 52 can also move along the lifting direction of the valve stem 2231. When the second movable part 52 descends, the valve stem 2231 is pushed downward, and the juice collection hole 2211 is opened; when the second movable part 52 rises, the valve stem 2231 slides upward and resets under the action of the second elastic part 2232, and the juice collection hole 2211 is closed.

[0110] The second driving mechanism 50 moves together with the cover pressing unit 30. When the cover pressing unit 30 is opened, the second driving mechanism 50 is completely separated from the juice collecting valve assembly 223. When the cover pressing unit 30 is closed, the second driving mechanism 50 is arranged corresponding to the juice collecting valve assembly 223, and the second movable member 52 is aligned with the valve stem 2231. Alternatively, the second driving mechanism 50 can also be arranged on the pot cover 221. When the pot unit 20 is pulled out of the housing 11, the second driving mechanism 50 moves together with the pot unit 20.

[0111] like Fig.13 As shown, the juice collecting valve assembly 223 further includes a sealing ring 2234, which is sleeved on the edge of the sealing plate 2233. When the juice collecting valve assembly 223 closes the juice collecting hole 2211, the sealing ring 2234 can improve the sealing between the sealing plate 2233 and the pot cover 221 to prevent the steam in the cooking cavity from overflowing from the juice collecting hole 2211.

[0112] like Fig.12 As shown, there are multiple juice collection holes 2211, and the multiple juice collection holes 2211 are circumferentially spaced around the valve stem 2231 and are opened on the pot cover 221. The multiple juice collection holes 2211 can increase the opening area on the pot cover 221, and when the sealing plate 2233 descends, the multiple juice collection holes 2211 can be opened at the same time, so that the steam in the cooking cavity can be quickly discharged, thereby improving the juice collection efficiency.

[0113] It is worth mentioning that the valve assembly may include a check valve 222, a juice collection valve assembly 223 and a pressure-limiting valve assembly 224, or may include only any one or two of the three, and the embodiment of the utility model does not make specific limitations here.

[0114] like Figure 1 , Figure 8 and Fig. 9 As shown, there is a gap 115 between one of the side walls of the door body 112 and the box body 111; or, there is a gap 115 between the control panel 113 and the door body 112. The pressure cooker also includes an exhaust assembly 60, and the exhaust assembly 60 includes a fan 61 and an exhaust passage 62. The air outlet of the fan 61 is connected to the inlet of the exhaust passage 62, and the outlet of the exhaust passage 62 is connected to the outside through the gap 115. The valve assembly is connected to the exhaust passage 62. The fan 61 can blow air into the exhaust passage 62 to control the flow direction of the gas in the exhaust passage 62. After the steam discharged through the valve assembly enters the exhaust passage 62, it can flow along the exhaust passage 62 to the outlet and be discharged from the housing 11 through the gap 115, so as to avoid the pressure in the housing 11 from increasing and causing safety hazards, and at the same time, it can also prevent the steam from contacting the housing 11 to produce condensed water or the steam with oil from remaining in the housing 11 and causing inconvenience in cleaning.

[0115] In one embodiment, the number of exhaust passages 62 corresponds to the number of valve assemblies and does not interfere with each other, and each valve assembly is connected to one exhaust passage 62. When the valve assembly includes the check valve 222, the juice collecting valve assembly 223, and the pressure limiting valve assembly 224, the number of exhaust passages 62 is three. The inlet of each exhaust passage 62 is connected to the fan 61, and the outlet of each exhaust passage 62 is connected to the gap 115. The steam exhausted from the valve assembly flows through the corresponding exhaust passages 62 and is discharged from the gap 115 to the housing 11.

[0116] like Fig. 9 As shown, in the illustrated embodiment, the exhaust passage 62 includes a main passage 621 and at least one sub-passage 622 connected to the main passage 621, each valve assembly is connected to a corresponding sub-passage 622, each sub-passage 622 is connected to the main passage 621, the fan 61 is connected to the inlet of the main passage 621, and the outlet of the main passage 621 is connected to the gap 115. The steam exhausted by each valve assembly is discharged into the main passage 621 through the corresponding sub-passage 622 without interfering with each other, and is discharged from the housing 11 through the outlet of the main passage 621 from the gap 115. The exhaust passage 62 has a simple structure and is easy to assemble.

[0117] Specifically, when the valve assembly includes the check valve 222, the juice collecting valve assembly 223 and the pressure limiting valve assembly 224, the number of the sub-channels 622 is three. Each valve assembly corresponds to one sub-channel 622, and along the gas flow direction of the main channel 621, the pressure limiting valve assembly 224, the check valve 222 and the juice collecting valve assembly 223 are sequentially connected to the main channel 621. During a cooking process, the pressure limiting valve assembly 224 is usually opened and closed multiple times in stages; the juice collecting valve assembly 223 is usually opened and closed once, and more steam is discharged from the juice collecting valve assembly 223; the check valve 222 is usually opened and closed once, and less steam is discharged from the check valve 222. Therefore, in order to prevent the steam discharged from the pressure limiting valve assembly 224 and the juice collecting valve assembly 223 from flowing back to the fan 61 when the fan 61 does not start working and affecting the normal use of the fan 61, the pressure limiting valve assembly 224 and the juice collecting valve assembly 223 are arranged at a position relatively far away from the fan 61.

[0118] like Figures 8 to 9 As shown, the exhaust assembly 60 further includes a hose 63 and a steam exhaust member 64, one end of the hose 63 is in communication with the inlet of the main channel 621, and the other end is in communication with the steam exhaust member 64, and the steam exhaust member 64 has a steam outlet in communication with the gap 115. Since the steam exhaust member 64 is connected to the steam exhaust channel 62 through the hose 63, when the position of the steam exhaust channel 62 and the housing 11 changes, the position of the steam exhaust member 64 can be ensured to remain unchanged, and the steam outlet of the steam exhaust member 64 is always in communication with the gap 115, which will not affect the normal exhaust of the exhaust assembly 60.

[0119] like Figures 9 and 10As shown, in the illustrated embodiment, the exhaust assembly 60 is arranged on the pressure cover unit 30, and the pressure cover 311 also includes an annular rib 3113 protruding from the pressure plate 3115, and the pressure plate 3115 is provided with an avoidance hole, wherein the avoidance hole corresponds to the stop valve 222, the pressure limiting valve assembly 224 or the juice collection hole 2211, and the annular rib 3113 surrounds the avoidance hole to connect the stop valve 222, the pressure limiting valve assembly 224 or the juice collection hole 2211 with the exhaust channel 62, that is, the annular rib 3113 surrounds the avoidance hole to form a sub-channel 622; each annular rib 3113 corresponds to a sub-channel 622, and each sub-channel 622 is independent of each other. When the cover unit 30 is opened, the annular rib 3113 is separated from the pot cover 221, so that each valve assembly is separated from the corresponding sub-channel 622; when the cover unit 30 is closed, the end of the annular rib 3113 away from the pressure plate 3115 is in contact with the pot cover 221, and each valve assembly is located in the corresponding sub-channel 622.

[0120] Among them, since the push rod mounting seat 43, the driving assembly 51 and the pressure limiting valve driving mechanism are all arranged outside the annular rib 3113, each annular rib 3113 is also provided with a third through hole for penetrating the first push rod 42, the driving rod 513 or the second push rod 72, the first push rod 42 is penetrated by the third through hole and connected to the first movable member 41 located in the annular rib 3113, and the second push rod 72 is penetrated by the third through hole and connected to the second movable member 52 located in the annular rib 3113. Among them, the inside of the annular rib 3113 refers to the space surrounded by the annular rib 3113.

[0121] like Figures 9 and 10 As shown, the flap assembly 33 also includes an air duct cover 333, and a rib plate 3322 is convexly provided on the side of the flap 332 away from the pressure plate 3115, and a second through hole 3321 communicating with the sub-channel 622 is provided on the flap 332. The flap 332, the rib plate 3322 and the air duct cover 333 are arranged to form a main channel 621. The steam discharged from the valve assembly can flow into the main channel 621 through the sub-channel 622 and the corresponding second through hole 3321. The exhaust assembly 60 uses the flap 332 of the flap assembly 33 as the bottom wall of the main channel 621 to avoid increasing the overall thickness of the flap assembly 33, and the flap 332 and the rib plate 3322 are detachably arranged to facilitate the user to clean the main channel 621.

[0122] Of course, in other embodiments, the exhaust assembly 60 can also be provided separately, for example, the exhaust assembly 60 includes a shell, a main channel 621 and at least one sub-channel 622 communicating with the main channel 621 are provided in the shell, and each valve assembly is correspondingly connected to a sub-channel 622. In addition, the shell of the exhaust assembly 60 can be fixed to the gland unit 30, or fixed to other positions in the housing 11, that is, it is separated from the gland unit 30. When the exhaust assembly 60 is separated from the gland unit 30, the pot unit 20 is pushed into the housing 11, and the valve assembly on the pot cover 221 is connected to the corresponding sub-channel 622; the pot unit 20 is pulled out of the housing 11, and the valve assembly is separated from the corresponding sub-channel 622. The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the technical features in the above-mentioned embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
