[0032] Pressure rice cookers are popular in the market because they cook rice that is soft and fluffy. However, pressure rice cookers generate a certain amount of pressure during the heating process, and the lid cannot be opened after the rice is cooked. It is necessary to wait for the pressure to drop before opening the lid. Therefore, users have to wait a long time. Or, if users open the lid during the cooking process, it is difficult to close the lid again due to the large amount of gas inside the pot.

[0033] The following is combined with Figures 1 to 18 The following describes embodiments of the present invention.

[0034] According to an embodiment of the present invention, in one aspect, a cover assembly for a cooking device is provided, including an inner cover 1 and a cover plate 2.

[0038] In one embodiment, such as Figure 3 and Figure 14 The protruding structure 103 includes a first protrusion 1031 and a second protrusion 1032, the second protrusion 1032 being higher than the first protrusion 1031, and the first exhaust valve assembly 4 being lower than the second exhaust valve assembly 5.

[0039] In this embodiment, the second protrusion 1032 is higher than the first protrusion 1031, and the first exhaust valve assembly 4 is lower than the second exhaust valve assembly 5, which can make full use of the space inside the cover assembly and reduce the overall thickness of the cover assembly.

[0040] In one embodiment, a first drive structure for driving the first exhaust valve assembly 4 is provided on the first protrusion 1031, the second exhaust valve assembly 5 includes a ball valve 501, and a mounting through hole 10321 is provided on one side of the second protrusion 1032. The second drive structure for driving the ball valve 501 is adapted to pass through the mounting through hole 10321 to drive the ball valve 501.

[0041] In this embodiment, by providing the first drive structure for driving the first exhaust valve assembly 4 on the first protrusion 1031, the space between the height difference between the first protrusion 1031 and the second protrusion 1032 can be fully utilized, thus making full use of the internal space of the cover assembly and reducing the overall thickness of the cover assembly. A mounting through hole 10321 is provided on one side of the second protrusion 1032. The second drive structure is adapted to pass through the mounting through hole 10321 to drive the ball valve 501, facilitating the driving of the ball valve 501 without increasing the overall thickness of the cover assembly.

[0042] In one embodiment, such as Figure 1 As shown, the second exhaust valve assembly 5 includes a column 502, a ball valve 501 located inside the column 502, and an opening 5021 on the side wall of the column 502. The second drive structure is adapted to pass through the opening 5021 to drive the ball valve 501.

[0043] In this embodiment, by providing an opening 5021 on the side wall of the column 502, the second drive structure can drive the ball valve 501.

[0044] In one embodiment, such as Figures 14 to 18 The first protrusion 1031 is provided with a groove 102. The first driving structure includes a first electromagnet 3, which is disposed in the groove 102. The first exhaust valve assembly 4 includes a float rod 401, a magnetic attractor 402 disposed at one end of the float rod 401 near the first electromagnet 3, and a sealing member 403 disposed on the float rod 401. When current is applied to the first electromagnet 3, a magnetic attraction force is generated between the first electromagnet 3 and the magnetic attractor 402, causing the float rod 401 to move the sealing member 403 to seal the first exhaust channel or When the first exhaust passage is opened and the first electromagnet 3 is de-energized, the float rod 401 resets and moves the sealing member 403 to open or seal the first exhaust passage; or, when the electromagnet is supplied with current in the first direction, a first force is generated between the electromagnet and the magnetic attractor 402 to seal the first exhaust passage with the sealing member 403; when the electromagnet is supplied with current in the second direction, a second force is generated between the electromagnet and the magnetic attractor 402 to move the float rod 401 and the sealing member 403 to open the first exhaust passage.

[0045] In this embodiment, when it is necessary to quickly open the lid assembly or close the lid assembly while it is hot, a current in the second direction is applied to the electromagnet. A second force is generated between the electromagnet and the magnetic attractor 402, causing the float rod 401 to move the sealing member 403 to open the exhaust channel, allowing steam in the pot cavity 10 to escape through the exhaust channel. When the cooking device is working normally, a current in the first direction is applied to the electromagnet. A first force is generated between the electromagnet and the magnetic attractor 402, causing the sealing member 403 to seal the exhaust channel, ensuring pressure in the inner pot cavity and enabling normal cooking. Alternatively, when it is necessary to quickly open the lid assembly or close the lid assembly while it is hot, a current is applied to the first electromagnet 3. A magnetic force is generated between the first electromagnet 3 and the magnetic attractor 402, causing the float rod 401 to move the sealing member 403 to open the exhaust channel, allowing steam in the pot cavity 10 to escape through the exhaust channel. When the cooking equipment is working normally, de-energizing the first electromagnet 3 causes the float rod 401 to reset, moving the sealing element 403 to seal the exhaust channel, ensuring pressure in the inner pot cavity and enabling normal cooking. Alternatively, when it is necessary to quickly open the lid assembly or close the lid assembly while it is hot, de-energizing the first electromagnet 3 causes the float rod 401 to reset, moving the sealing element 403 to open the exhaust channel, allowing steam in the inner pot cavity 10 to escape through the exhaust channel. When the cooking equipment is working normally, current is applied to the first electromagnet 3, generating a magnetic attraction between the first electromagnet 3 and the magnetic element 402, causing the float rod 401 to move the sealing element 403 to seal the exhaust channel, ensuring pressure in the inner pot cavity and enabling normal cooking. The groove 102 provided in the first protrusion 1031 facilitates the positioning and installation of the first electromagnet 3, improving assembly efficiency.

[0046] Specifically in one embodiment, such as Figure 13 and Figure 14 As shown, the first electromagnet 3 is circular, and the groove 102 is also circular in shape. The groove 102 has an opening at the top, and the first electromagnet 3 is inserted into the groove 102 from top to bottom.

[0047] In one embodiment, when current is applied to the first electromagnet 3, a magnetic attraction force is generated between the first electromagnet 3 and the magnetic attractor 402, causing the float rod 401 to move the sealing member 403 to seal the first exhaust passage. When the first electromagnet 3 is de-energized, under the action of gravity, the float rod 401 resets and moves the sealing member 403 to open the first exhaust passage.

[0048] In this embodiment, when the cooking equipment is working normally, current is applied to the first electromagnet 3, generating a magnetic attraction between the first electromagnet 3 and the magnetic attractor 402, causing the float rod 401 to move upward. This moves the sealing member 403 upward to seal the first exhaust channel, ensuring the pressure in the inner pot cavity and enabling normal cooking. When it is necessary to quickly open the lid assembly or close the lid assembly while it is hot, the first electromagnet 3 is de-energized. Under the action of gravity, the float rod 401 resets, causing the sealing member 403 to move downward to open the first exhaust channel, allowing steam in the inner pot cavity 10 to escape through the first exhaust channel.

[0049] In an alternative embodiment, when current is applied to the first electromagnet 3, a magnetic attraction force is generated between the first electromagnet 3 and the magnetic attractor 402, causing the float rod 401 to move upward, which in turn moves the seal 403 upward to open the first exhaust channel. When the first electromagnet 3 is de-energized, under the action of gravity, the float rod 401 resets and moves the seal 403 to seal the first exhaust channel.

[0050] In this embodiment, when it is necessary to quickly open the lid assembly or close the lid assembly while it is hot, current is applied to the first electromagnet 3. A magnetic force is generated between the first electromagnet 3 and the magnetic attractor 402, causing the float rod 401 to move upwards. This moves the sealing member 403 upwards to open the first exhaust channel, allowing steam in the inner pot cavity 10 to escape through the first exhaust channel. When the cooking equipment is working normally, the first electromagnet 3 is de-energized. Under the influence of gravity, the float rod 401 moves downwards, causing the sealing member 403 to move downwards to seal the first exhaust channel. This ensures the pressure in the inner pot cavity and allows for normal cooking.

[0051] In an alternative embodiment, an elastic element is provided between the float rod 401 and the cover plate 2. When the first electromagnet 3 is de-energized, under the action of gravity and the restoring force of the elastic element, the float rod 401 resets and drives the seal 403 to move to open the first exhaust channel.

[0052] In this embodiment, when the cooking equipment is working normally, current is applied to the first electromagnet 3, generating a magnetic attraction between the first electromagnet 3 and the magnetic attractor 402. This magnetic attraction overcomes the gravity of the float rod 401 and the elastic force of the elastic member, causing the float rod 401 to move upward. This, in turn, causes the sealing member 403 to move upward to seal the first exhaust channel, ensuring the pressure in the inner pot cavity and enabling normal cooking. When it is necessary to quickly open the lid assembly or close the lid assembly while it is hot, the first electromagnet 3 is de-energized. Under the action of gravity and the restoring force of the elastic member, the float rod 401 resets, causing the sealing member 403 to move downward to open the first exhaust channel. Steam in the inner pot cavity 10 can then be discharged through the first exhaust channel.

[0053] In one embodiment, the first force is attraction and the second force is repulsion.

[0054] In this embodiment, when it is necessary to quickly open the lid assembly or close the lid assembly while it is hot, a current in the second direction is applied to the electromagnet. The electromagnet and the magnetic attractor 402 generate a repulsive force, causing the float rod 401 to move the sealing member 403 to open the first exhaust channel. Steam in the inner pot cavity 10 can then be discharged through the first exhaust channel. When the cooking device is working normally, a current in the first direction is applied to the electromagnet. The electromagnet and the magnetic attractor 402 generate an attractive force, causing the sealing member 403 to seal the first exhaust channel, ensuring the pressure in the inner pot cavity and enabling normal cooking.

[0055] In one specific embodiment, when it is necessary to quickly open the lid assembly or close the lid assembly while it is hot, a current in the second direction is applied to the electromagnet. The electromagnet and the magnetic attractor 402 generate a repulsive force, causing the float rod 401 to move the sealing member 403 downwards to open the first exhaust channel. Steam in the inner pot cavity 10 can then be discharged through the first exhaust channel. When the cooking device is working normally, a current in the first direction is applied to the electromagnet. The electromagnet and the magnetic attractor 402 generate an attractive force, causing the sealing member 403 to move upwards to seal the first exhaust channel. This ensures the pressure in the inner pot cavity and enables normal cooking.

[0056] In an alternative embodiment, the first force is a repulsive force and the second force is an attractive force.

[0057] In this embodiment, when it is necessary to quickly open the lid assembly or close the lid assembly while it is hot, a current in the second direction is applied to the electromagnet. An attraction is generated between the electromagnet and the magnetic attractor 402, causing the float rod 401 to move the sealing member 403 to open the first exhaust channel. Steam in the inner pot cavity 10 can then be discharged through the first exhaust channel. When the cooking device is working normally, a current in the first direction is applied to the electromagnet. A repulsive force is generated between the electromagnet and the magnetic attractor 402, causing the sealing member 403 to seal the first exhaust channel. This ensures the pressure in the inner pot cavity and enables normal cooking.

[0058] In one specific embodiment, when it is necessary to quickly open the lid assembly or close the lid assembly while it is hot, a current in the second direction is applied to the electromagnet. The electromagnet and the magnetic attractor 402 generate an attractive force, causing the float rod 401 to move the sealing member 403 upwards to open the first exhaust channel. Steam in the inner pot cavity 10 can then be discharged through the first exhaust channel. When the cooking device is working normally, a current in the first direction is applied to the electromagnet. The electromagnet and the magnetic attractor 402 generate a repulsive force, causing the sealing member 403 to move downwards to seal the first exhaust channel. This ensures the pressure in the inner pot cavity and enables normal cooking.

[0059] In one specific embodiment, the electromagnet is connected to a power source. The upper end of the magnetic attractor 402 is the N pole. When a current in the first direction is applied to the electromagnet, the lower end of the electromagnet becomes the S pole. An attractive force is generated between the electromagnet and the magnetic attractor 402, causing the sealing member 403 to move upward and seal the first exhaust channel. This ensures the pressure in the inner pot cavity and enables normal cooking. When the two poles of the power source are reversed, the current applied to the electromagnet is changed to the second direction, and the lower end of the electromagnet becomes the N pole. A repulsive force is generated between the electromagnet and the magnetic attractor 402, causing the float rod 401 to move the sealing member 403 downward to open the first exhaust channel. Steam in the inner pot cavity 10 can then be discharged through the first exhaust channel.

[0060] Specifically, the first electromagnet 3 is connected to a power line 9, which is connected to a power board 8. The power board 8 can control the flow of current into or de-energize the first electromagnet 3.

[0061] In one embodiment, such as Figure 14 As shown, a rib 1021 is provided in the groove 102, and the rib 1021 is interference-fitted with the first electromagnet 3.

[0062] In this embodiment, by providing a rib 1021 in the groove 102, the rib 1021 is interference-fitted with the first electromagnet 3. Therefore, after the first electromagnet 3 is embedded in the groove 102, the first electromagnet 3 is fixed in the groove 102 without the need for other fasteners. The structure is simple and compact and easy to assemble.

[0063] In one specific embodiment, the rib 1021 is disposed on the side wall of the groove 102 and extends along the depth direction of the groove 102. Multiple ribs 1021 are provided at intervals along the circumference of the groove 102.

[0064] In one embodiment, the cover assembly further includes a faceplate 7, which abuts against the upper end of the first electromagnet 3.

[0065] In this embodiment, the face cover 7 abuts against the upper end of the first electromagnet 3, so the first electromagnet 3 can be limited at the upper end of the first electromagnet 3 to prevent the first electromagnet 3 from shaking in the vertical direction.

[0066] In one specific embodiment, the face cover 7 and the inner cover 1 are connected by a snap and / or screws. After the face cover 7 and the inner cover 1 are connected, the face cover 7 abuts against the upper end of the first electromagnet 3.

[0067] Specifically, the cover 7 has an operating area, through which users can operate the cooking equipment.

The first connecting arm 1201 is provided with a magnetic structure, which has a first position and a second position under the drive of the second electromagnet 11. The second connecting arm 1202 constitutes a second driving structure. The first exhaust valve assembly 4 includes a float rod 401, a magnetic attractor 402 provided at one end of the float rod 401, and a sealing member 403 provided on the float rod 401. In the first position, the magnetic force between the magnetic structure and the magnetic attractor 402 causes the float rod 401 to move so that the sealing member 403 opens the first exhaust channel. In the second position, the magnetic force between the magnetic structure and the magnetic attractor 402 causes the float rod 401 to move so that the sealing member 403 closes the first exhaust channel.

[0069] In this embodiment, the connecting rod 12 has a first connecting arm 1201 and a second connecting arm 1202. The first connecting arm 1201 is provided with a magnet structure, and the second connecting arm 1202 constitutes a second driving structure. Therefore, when the second electromagnet 11 drives the connecting rod 12 to move, it can simultaneously drive the magnet structure and the second connecting arm 1202 to move synchronously. The structure is simple and compact, which can avoid occupying a large space in the cover assembly.

[0070] In one specific embodiment, the second electromagnet 11 is fixed to the inner cover 1 by a pressure cap 16.

[0071] In one specific embodiment, an air inlet is provided at the inlet of the first exhaust channel, and the air inlet is connected to the inner cavity 10 of the pot. The first exhaust valve assembly 4 is adapted to open or block the air inlet under the drive of the drive assembly.

[0072] In this embodiment, when the first exhaust valve assembly 4 opens the air inlet, steam can enter the first exhaust channel through the air inlet and then be discharged through the air outlet 101. When the first exhaust valve assembly 4 blocks the air inlet, steam cannot enter the first exhaust channel.

[0073] In one specific embodiment, in the first position, the magnetic force between the magnet structure and the magnetic attractor 402 causes the float rod 401 to move so that the seal 403 opens the air inlet; in the second position, the magnetic force between the magnet structure and the magnetic attractor 402 causes the float rod 401 to move so that the seal 403 closes the air inlet.

[0074] In one specific embodiment, when the magnet structure is in the first position, the repulsive force between the magnet structure and the magnetic attractor 402 causes the float rod 401 to move downward so that the seal 403 opens the air inlet. When the magnet structure is in the second position, the magnetic attraction between the magnet structure and the magnetic attractor 402 causes the float rod 401 to move upward so that the seal 403 closes the air inlet.

[0075] In one specific embodiment, an annular mounting groove is provided near the lower end of the float rod 401, and a seal 403 is installed in the mounting groove, with a portion of the seal 403 protruding outside the mounting groove. When the seal 403 abuts against the lower end of the air inlet, the seal 403 blocks the air inlet.

[0076] Specifically in one embodiment, such as Figure 6 As shown, the seal 403 includes an annular main body 4031, a first annular sealing portion 4032 and a second annular sealing portion 40333 disposed on the outer periphery of the annular main body 4031. The first annular sealing portion 4032 extends obliquely upward, and the second annular sealing portion 40333 extends obliquely downward. An angle is formed between the first annular sealing portion 4032 and the second annular sealing portion 40333, and a gap exists between them. When the magnet structure is in the second position, the magnetic attraction between the magnet structure and the magnetic attractor 402 causes the float rod 401 to move upward, thereby causing the seal 403 to move upward. The first annular sealing portion 4032 abuts against and deforms with the area of ​​the cover plate 2 around the air inlet 201, thereby sealing the air inlet 201. Because an angle is formed between the first annular sealing portion 4032 and the second annular sealing portion 40333, and a gap exists between them, the first annular sealing portion 4032 is more likely to deform, thus ensuring sealing performance.

[0077] In one embodiment, the first exhaust valve assembly 4 further includes a magnet cover 404 connected to a float rod 401, and a magnetic attractor 402 positioned between the magnet cover 404 and the float rod 401.

[0078] In this embodiment, by providing a magnet cover 404, the magnetic suction component 402 is limited between the magnet cover 404 and the float rod 401, which facilitates the positioning and installation of the magnetic suction component 402.

[0079] In an alternative embodiment, the magnet cover 404 may be omitted, and a groove 102 may be provided at the top of the float rod 401, with the magnetic component 402 embedded in the groove 102. Alternatively, the magnetic component 402 may be glued to the top of the float rod 401.

[0080] In one embodiment, the magnet cover 404 is connected to the float rod 401 by a thread.

[0081] In this embodiment, the magnet cover 404 and the float rod 401 are connected by threads, which facilitates the connection between the magnet cover 404 and the float rod 401 and can improve assembly efficiency.

[0082] In an alternative embodiment, the magnet cover 404 and the float rod 401 can be connected by a snap-fit.

[0083] In one embodiment, the magnet structure is adapted to move along a first direction under the drive of the drive structure, and the magnet structure includes a connecting magnet 13, the connecting magnet 13 having opposite magnetic poles at both ends along the first direction.

[0084] In this embodiment, the magnet structure is adapted to move along a first direction under the drive of the driving structure. The magnet structure includes a connecting magnet 13, which has opposite magnetic poles at both ends along the first direction. Only one connecting magnet 13 is provided, making the structure simpler.

[0085] In one specific embodiment, the connecting rod magnet 13 moves horizontally under the drive of the driving structure, and the magnetic poles of the connecting rod magnet 13 are opposite at both ends along the horizontal direction.

[0086] More specifically, such as Figures 4 to 18 As shown, the right end of the connecting rod magnet 13 is the S pole, the left end of the connecting rod magnet 13 is the N pole, and the upper end of the magnetic suction member 402 is the N pole. When the right end of the connecting rod magnet 13 is directly opposite the upper end of the magnetic suction member 402, the magnetic attraction between the connecting rod magnet 13 and the magnetic suction member 402 causes the float rod 401 to move upward so that the seal 403 closes the air inlet. When the left end of the connecting rod magnet 13 is directly opposite the upper end of the magnetic suction member 402, the repulsive force between the connecting rod magnet 13 and the magnetic suction member 402 causes the float rod 401 to move downward so that the seal 403 opens the air inlet.

[0087] In one embodiment, such as Figures 9 to 11 As shown, the magnet structure includes a first magnet 14 and a second magnet 15 arranged at intervals. The magnetic poles of the first magnet 14 facing the magnetic attractor 402 are opposite to the magnetic poles of the second magnet 15 facing the magnetic attractor 402.

[0088] In this embodiment, the magnet structure includes a first magnet 14 and a second magnet 15 spaced apart. The magnetic poles of the first magnet 14 facing the magnetic chuck 402 are opposite to those of the second magnet 15 facing the magnetic chuck 402. Therefore, the magnetic force between the first magnet 14 and the magnetic chuck 402 when they are facing each other is opposite to that between the second magnet 15 and the magnetic chuck 402 when they are facing each other, thereby driving the float rod 401 to move. By setting the first magnet 14 and the second magnet 15, the magnetic poles of the magnets can be accurately aligned, reducing the problem of the float rod 401 getting stuck.

[0089] In one specific embodiment, the upper end of the magnetic attractor 402 is the N pole, the lower end of the first magnet 14 is the S pole, and the lower end of the second magnet 15 is the N pole. When the first magnet 14 is directly opposite the magnetic attractor 402, the magnetic attraction between the first magnet 14 and the magnetic attractor 402 causes the float rod 401 to move upward so that the seal 403 closes the air inlet. When the second magnet 15 is directly opposite the magnetic attractor 402, the repulsive force between the second magnet 15 and the magnetic attractor 402 causes the float rod 401 to move downward so that the seal 403 opens the air inlet.

[0090] In one embodiment, the first connecting arm 1201 includes a first horizontal portion 12011, a second horizontal portion 12012, and a bent portion. The first horizontal portion 12011 is close to the second electromagnet 11, the second horizontal portion 12012 is movably disposed on the first protrusion 1031, the magnet structure is disposed on the second horizontal portion 12012, and the bent portion connects the first horizontal portion 12011 and the second horizontal portion 12012.

[0091] In this embodiment, the first connecting arm 1201 includes a first horizontal portion 12011, a second horizontal portion 12012, and a bending portion. The first horizontal portion 12011 is close to the second electromagnet 11, and the second horizontal portion 12012 is movably disposed on the first protrusion 1031, which can make full use of the space inside the cover assembly and reduce the overall thickness of the cover assembly.

[0092] In one specific embodiment, the inner cover 1 is provided with a vent 101, and the cover plate 2 and the inner cover 1 form a steam chamber 6. The vent 101 is located at the top of the steam chamber 6, and the exhaust channel is connected to the steam chamber 6. When venting, the steam in the inner pot cavity first enters the first exhaust channel and the second exhaust channel, then enters the steam chamber 6, and finally exits from the vent 101.

[0093] Secondly, this utility model also provides a cooking device, including a lid assembly for the cooking device.

[0094] The cooking device includes an inner lid 1 comprising a lid body and a protruding structure 103 located on the lid body. A mounting cavity is formed on the lower side of the protruding structure 103. A first exhaust valve assembly 4 and a second exhaust valve assembly 5 extend into the mounting cavity, fully utilizing the internal space of the lid body assembly and reducing the overall thickness of the lid body assembly. Furthermore, by providing the first exhaust valve assembly 4 and the second exhaust valve assembly 5, exhaust can be performed simultaneously, increasing the exhaust speed and allowing steam in the pot cavity 10 to be quickly discharged, preventing difficulty in closing the lid when hot.

[0095] In one embodiment, the cooking device is a rice cooker or an electric pressure cooker.

[0096] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
