A pot cover assembly 1 for a cooking appliance according to an embodiment of the present invention will be described with reference to fig. 1 to 6.

Referring to fig. 1 to 3, a pot cover assembly 1 for a cooking appliance according to an embodiment of the present invention may include: pot lid body 100, exhaust valve 200, magnetic member 300, coil and brush 500.

Specifically, the exhaust valve 200 may be connected to the pot cover body 100, and the exhaust valve 200 may have an exhaust valve passage 210, and the exhaust valve passage 210 may communicate the cooking cavity of the cooking appliance with the outside. Therefore, in the working process of the cooking appliance, gas in the cooking cavity can be exhausted to the outside through the exhaust valve passage 210, so that the pressure in the cooking cavity is kept in a certain range, and the cooking efficiency of the cooking appliance and the taste of food materials are improved.

The gas in the cooking cavity has certain energy, and if the gas is directly exhausted to the outside, the energy of the gas cannot be fully utilized, so that energy waste is caused. In the invention, the pot cover assembly 1 can utilize the exhaust process of the cooking utensil to generate kinetic energy and convert the kinetic energy into electric energy, and the electric energy can be further utilized to realize the purpose of energy conservation.

Specifically, as shown in fig. 1 to 3, the exhaust valve 200 includes an exhaust valve body 10, and the exhaust valve body 10 can rotate with respect to the pot cover body 100. The exhaust valve passage 210 is configured such that the exhaust valve body 10 can be rotated by the gas in the exhaust valve passage 210. The magnetic member 300 may be connected to the lid body 100 or the body of the cooking appliance to fix the magnetic member 300. The magnetic member 300 can generate a magnetic field, the coil is located in the magnetic field generated by the magnetic member 300, and the coil can cut magnetic lines of force of the magnetic field under the driving of the exhaust valve body 10 to form an electromotive force. In addition, as shown in fig. 2, the brush 500 is connected to the pot cover body 100, and the brush 500 is electrically connected to the coil.

Thus, the coil, the magnetic member 300, and the brush 500 may constitute a rotor structure, and the exhaust valve 200 and the rotor structure constitute an exhaust valve power generation device. When the gas in the cooking cavity is exhausted through the exhaust valve passage 210, the exhaust valve body 10 is driven by the gas to rotate, and meanwhile, the coil is driven to rotate, the coil cuts the magnetic induction line to form electromotive force, so that the purpose of generating kinetic energy by exhausting and further converting the kinetic energy into electric energy is achieved. The generated electric energy can be led out through the matching of the electric brush 500, and the led-out electric energy can be utilized so as to improve the energy utilization rate.

For example, in some embodiments, the brush 500 may be electrically connected to a low power device of the cooking appliance to supply power to the low power device, and the cooking appliance does not need to additionally supply power to the low power device, or reduces additional power supply, which is beneficial to saving electric energy, reducing power consumption of the cooking appliance, and saving more energy. In other embodiments, the lid assembly 1 may further include an energy storage device, such as a battery, which may be electrically connected to the brush 500 to store the electric energy drawn by the brush 500. And the energy storage device can supply power to the power consumption parts of the cooking utensil to provide electric energy when the power consumption parts need to consume power, for example, after the cooking utensil is powered off, the energy storage device can maintain the work of low power consumption parts such as a clock in the cooking utensil, and a user does not need to additionally install a battery or charge, so that the energy waste is reduced. Not only realizes energy saving and consumption reduction, but also can ensure that the power supply of the power consumption part is more stable and durable, and the power storage and the power supply can not be carried out simultaneously, thus the use is more convenient.

According to the pot cover assembly 1 for the cooking utensil, the exhaust valve body 10, the coil, the magnetic piece 300 and the electric brush 500 are matched, kinetic energy can be generated by exhaust of the cooking utensil and converted into electric energy, gas energy is fully utilized, energy is saved, consumption is reduced, the structure is compact, and the occupied space is small.

It should be noted that, in the present invention, the coil is rotated by the exhaust valve body 10. Here, the coil may be directly connected to the exhaust valve body 10, that is, the exhaust valve 200 is integrated with the rotor structure to form the rotor exhaust valve, so that the structure is more compact and the occupied space is smaller. The coil can also be indirectly connected with the exhaust valve body 10 in a transmission manner, so that the coil can be driven by the exhaust valve body 10 to rotate to indirectly generate electric energy.

For example, in some embodiments, a coil is disposed on the exhaust valve body 10, and the coil and the exhaust valve body 10 are coaxially disposed, and the rotation of the exhaust valve body 10 can drive the coil to rotate. For another example, in other embodiments, the lid assembly 1 may further include a transmission member, the transmission member may be in transmission connection with the exhaust valve body 10, and the coil may be disposed on the transmission member or in transmission connection with the transmission member, so as to transmit the rotation of the exhaust valve body 10 to the coil.

Alternatively, the transmission member may be a transmission gear, which cooperates with the coil, the magnetic member 300 and the brush 500 to form a gear rotor, and the transmission member may be a transmission belt, etc., which are within the scope of the present invention.

According to some embodiments of the present invention, as shown in fig. 1 and 3, a slip ring 400 may be electrically connected between the brush 500 and the coil, in other words, the coil may be electrically connected with the slip ring 400, and the slip ring 400 may be electrically connected with the brush 500. When the exhaust valve body 10 rotates, the collecting ring 400 can rotate under the rotation of the exhaust valve body 10, so that the coil continuously rotates, meanwhile, the electric energy generated by the coil is transmitted to the collecting ring 400, the collecting ring 400 is further transmitted to the brush 500 and is transmitted outwards by the brush 500, and therefore, the electric energy transmission between the rotating position and the fixed position is realized. The brush 500 may not directly contact with the coil, so as to prevent the coil from causing sprain in the rotation process, and the electric transmission structure is simpler and more reliable.

In some embodiments of the present invention, as shown in fig. 1 and 3, the exhaust valve 200 may further include an exhaust valve core 20, and the exhaust valve core 20 may be connected to the lid body 100 to connect the exhaust valve 200 to the lid body 100.

As shown in fig. 3, the exhaust valve passage 210 may include a spool passage 201 and a valve body passage 101, wherein the spool passage 201 is provided in the exhaust spool 20, and the valve body passage 101 is provided in the exhaust valve body 10. The valve body passage 101 may include a first air passage 102 and a second air passage 103 communicating with each other, and the first air passage 102 into which an upper portion of the exhaust valve spool 20 may be inserted to communicate the spool passage 201 with the valve body passage 101.

In addition, as shown in fig. 5 and fig. 6, the second air passage 103 extends obliquely with respect to the radial direction of the exhaust valve body 10, so that when air flows through the second air passage 103, a driving force for driving the exhaust valve body 10 to rotate with respect to the exhaust valve core 20 can be formed, and when the exhaust valve body 10 rotates, the exhaust valve core 20 does not rotate with the exhaust valve body 10, which not only makes the exhaust valve core 20 and the lid body 100 more firm, but also is beneficial to improving the sealing performance of the cooking cavity. For example, in the embodiment shown in fig. 5 and 6, in the direction away from the center of the exhaust valve body 10 in the radial direction of the exhaust valve body 10, the second gas passage 103 extends obliquely in the counterclockwise direction with respect to the radial direction of the exhaust valve body 10, and when gas flows through the second gas passage 103, the gas flows in the counterclockwise direction substantially as shown by the curved arrow in the figure, and the recoil force of the gas flow acts on the inner wall surface of the second gas passage 103, so that the exhaust valve body 10 rotates in the clockwise direction.

In the present invention, a part of the second gas passage 103 may extend obliquely with respect to the radial direction of the exhaust valve body 10, or the entire second gas passage 103 may extend obliquely with respect to the radial direction of the exhaust valve body 10, which may form a driving force for driving the exhaust valve body 10 to rotate with respect to the exhaust valve core 20 when the gas flows through the second gas passage 103.

Further, as shown in fig. 3, the exhaust valve body 10 can move up and down along the axial direction of the exhaust valve body 10 according to the air pressure change in the cooking chamber. When the air pressure is increased to exceed the set condition, the exhaust valve body 10 moves upwards under the action of the air pressure to enable the valve core channel 201 and the valve body channel 101 to be communicated, and further enable the cooking cavity to be communicated with the outside, and the air in the cooking cavity can be exhausted to the outside to reduce the air pressure in the cooking cavity. When atmospheric pressure reduces to being less than the settlement condition gradually, exhaust valve body 10 moves down under the action of gravity to make case passageway 201 and valve body passageway 101 cut off, and then make culinary art chamber and external world cut off, can keep in the pressure value or the pressure range of settlement in the culinary art chamber, satisfy different edible material culinary art demands.

According to some embodiments of the present invention, as shown in fig. 3-6, the exhaust valve body 10 may be provided with a plurality of gas passing ports 111, and the plurality of gas passing ports 111 may be located adjacent to the center of the exhaust valve body 10 and spaced apart in the circumferential direction of the exhaust valve body 10. The second air passages 103 may also include a plurality of second air passages 103, the plurality of second air passages 103 may be distributed along the circumferential direction of the exhaust valve core 20, inner ends of the plurality of second air passages 103 may be communicated with the first air passage 102 through a plurality of air passing ports 111 corresponding to one another, and an outer end of each second air passage 103 may have an exhaust port 141 communicated with the outside. Here, the "inner end" of the second gas passage 103 refers to an end of the second gas passage 103 close to the center of the exhaust valve body 10 in the radial direction of the exhaust valve body 10, and the "outer end" refers to an end of the second gas passage 103 far from the center of the exhaust valve body 10 in the radial direction of the exhaust valve body 10.

Therefore, the gas in the first gas passage 102 can be divided into a plurality of second gas passages 103 through the plurality of gas passing openings 111, and flows along the second gas passages 103, and finally is discharged to the outside through the gas discharge opening 141. When gas flows in a plurality of second air passages 103 spaced along the circumferential direction of the exhaust valve body 10, the gas can act on the exhaust valve body 10 at a plurality of positions in the circumferential direction of the exhaust valve body 10, so that the driving force received by the exhaust valve body 10 is more uniform, the rotation of the exhaust valve body 10 is more stable, and the resistance is smaller.

In addition, the gas passing port 111 and the gas outlet 141 corresponding to each second gas passage 103 are respectively arranged at the inner end and the outer end of the second gas passage 103, that is, in the axial projection of the exhaust valve body 10, the gas passing port 111 and the gas outlet 141 are arranged in a staggered manner, so that the gas tends to flow in the second gas passage 103 along the direction perpendicular to the axial direction, and further, a driving force perpendicular to the axial direction can be applied to the exhaust valve body 10. And the second gas passage 103 extends obliquely with respect to the radial direction of the exhaust valve body 10, so that the driving force does not pass through the axis of the exhaust valve body 10, so that the driving force can drive the exhaust valve body 10 to rotate.

It should be noted that the number of the second air duct 103, the air passing port 111 and the exhaust port 141 is not particularly limited in the present invention. For example, in the example shown in fig. 4 to 6, the second air path 103, the air passing port 111, and the exhaust port 141 are respectively three and arranged in one-to-one correspondence. In other embodiments, the second air duct 103, the air passing opening 111 and the air discharging opening 141 are two, four, five or more, and are disposed in a one-to-one correspondence.

Further, as shown in fig. 5 and 6, two adjacent second gas passages 103 may be separated by a partition wall 12, so that gas may flow from the gas passing port 111 to the corresponding gas outlet 141 along each second gas passage 103, without leaking or flowing to the adjacent second gas passages 103 to affect the driving effect.

As shown in fig. 5, the partition wall 12 may include: a first wall segment 121 and a second wall segment 122. Wherein the first wall section 121 extends from the inside to the outside in the radial direction of the exhaust valve body 10, one end of the second wall section 122 may be connected to the outer end of the first wall section 121, the distance of the second wall section 122 from the center of the exhaust valve core 20 increases in the direction from the end of the second wall section 122 connected to the first wall section 121 to the other end of the second wall section 122, and the second wall section 122 is disposed obliquely with respect to the first wall section 121.

In other words, the first wall section 121 extends from the inside to the outside in the radial direction of the exhaust valve body 10, the second wall section 122 extends obliquely from the inside to the outside with respect to the radial direction of the exhaust valve body 10, the second wall section 122 extends in a direction different from the first wall section 121, and the partition wall 12 extends in a bent manner from the inside to the outside, so that the inner side wall surface of the second air passage 103 extends in a bent manner.

As shown in fig. 5 and 6, each gas vent 111 may be provided between two adjacent first wall sections 121, and each gas vent 111 may extend along the circumferential direction of the exhaust valve body 10 to increase the opening size of the gas vent 111, thereby increasing the gas flow rate.

In some embodiments, there are four second air passages 103, and four partition walls 12 are bent and extended in the counterclockwise direction, so that the four partition walls 12 substantially assume a swastika structure, each gas passage 111 is respectively located between two adjacent first wall segments 121 and is adjacent to the middle of the swastika structure, and the four gas outlets 141 are respectively located at the end of the swastika structure and are adjacent to one side of each second wall segment 122 in the clockwise direction. When the gas flows from the gas passing opening 111 to the gas outlet 141 along each second gas passage 103, the recoil force of the gas can act on the inner side wall surface of the partition wall 12, which is bent and extended at one side in the counterclockwise direction, so as to drive the exhaust valve body 10 to rotate, the driving force and the partition wall 12 act more fully, and the utilization rate of the recoil force of the gas is higher.

In some embodiments of the present invention, as shown in fig. 3-6, the exhaust valve body 10 may include: an inner valve body 11 and an outer housing 14. As shown in fig. 3 and 5, a first air passage 102 may be provided in the inner valve body 11, the first air passage 102 may extend in the axial direction of the inner valve body 11, and a gas passing port 111 and a partition wall 12 may be provided on the top surface of the inner valve body 11, respectively. As shown in fig. 2 to 4, the outer cover 14 may cover the inner valve body 11, and the outer cover 14 and the inner valve body 11 may be connected in a snap-fit manner, so that the connection is simple and firm, and the assembly is easy. Second air flue 103 is located between inner valve body 11 and the outer cover body 14, and second air flue 103 is injectd jointly to the top surface of inner valve body 11, the top surface of outer cover body 14, and the top surface of outer cover body 14 can be located to gas vent 141, and the simple structure of exhaust valve body 10, structural design is reasonable, and it is easier to process.

According to a further embodiment of the present invention, as shown in fig. 3 and 5, an upper end of the first air channel 102 may be opened to form an open opening, a mounting post 13 may be inserted into the open opening, the mounting post 13 may be provided with a plug 131, and the plug 131 may plug an upper end of the spool passage 201 to block the spool passage 201 and the valve body passage 101. The plug 131 moves up and down along with the exhaust valve body 10 to realize the switching between the connection and the disconnection of the valve core channel 201 and the valve body channel 101.

Further, as shown in fig. 5, the inner ends of the plurality of partition walls 12 are connected to the mounting post 13, and the mounting post 13 and the plurality of first wall sections 121 may be partitioned to open to form the plurality of gas passing ports 111 without providing a structure for forming the gas passing ports 111, and the structure of the exhaust valve body 10 is simpler.

In some embodiments of the present invention, as shown in fig. 3, a slip ring 400 may be disposed at a lower portion of the exhaust valve body 10 to facilitate electrical connection between the slip ring 400 and the brush 500, so that the structure is more compact.
