[0039] This arrangement allows the air inlet or outlet baffle to be exposed outside the guide slot, while the gear can act on the rack structure in the portion exposed from the guide slot. This arrangement improves the stability of the connection between the gear and rack, preventing them from coming out of place, and ultimately improving heat dissipation.
[0040] 10. The rice cooker lid provided by the present invention, the heat collecting fins include: linear fins, with two ends corresponding to the air inlet and the air outlet respectively; and a plurality of groups of streamlined fins symmetrically arranged on both sides of the linear fins.

[0055] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0056] Example 1
[0057] This embodiment provides a rice cooker cover, such as Figure 1-Figure 5 As shown, including:
[0058] The face cover is provided with an inner cover inside and a face cover is provided on the outside, which is the part that the user can directly see;
[0059] The support plate 1 is arranged in the inner cover.
[0060] While the structure of the support plate 1 itself is not limited, it is preferably a steel cover. The steel cover provides a stable connection to the rice cooker body, preventing the cover from separating from the body when internal pressure increases. By providing a heat shield structure on the steel cover, the structural stability of the steel cover can be fully utilized while avoiding the need for a separate structure, helping to reduce costs and structural complexity. In this embodiment, the support plate 1 itself is made of a material with average thermal conductivity.
[0061] The heat-insulating cover plate, wherein the support plate 1 is arranged between the heat-insulating cover plate and the inner cover;
[0062] The insulation cover itself is made of metal material such as aluminum, and is provided with steam holes for steam to pass through. The insulation cover itself faces the front of the food and is used to receive heat;
[0063] The heat shield 2 is made of heat-insulating material;
[0064] Specifically, the heat insulation cover 2 itself is made of materials such as polyurethane foam board, glass fiber board, thermal insulation paper, etc., so as to avoid heat exchange between the heat insulation cover 2 and the outside world.
[0065] The area of the support plate located inside the heat shield is provided with a heat conducting portion, which can realize rapid heat collection.
[0066] In this embodiment, the structure of the heat conducting portion itself is not limited, as long as it can achieve heat concentration. As an embodiment, the heat conducting portion can be a metal plate disposed on the support plate, such as an iron plate, an aluminum plate, or a copper plate. The metal plate itself has good thermal conductivity and can achieve rapid heat collection. As another embodiment, the heat conducting portion can be a recessed portion disposed on the support plate. In this case, heat will accumulate within the recessed portion and further penetrate the support plate into the interior of the heat shield 2.
[0067] As a preferred embodiment, the heat conducting portion itself is configured as a heat-transmitting hole 101. In this embodiment, the heat-transmitting hole 101 itself can be a through hole or a blind hole. When the heat-transmitting hole 101 itself is a blind hole, the space inside the blind hole can collect heat. As a preferred embodiment, the heat-transmitting hole itself is configured as a through hole.
[0068] The shape of the heat-through hole 101 itself is not limited and can be a circular hole, an elliptical hole, or other shapes. The location of the heat-through hole 101 itself is not limited and can be located near the center of the support plate or at a position off-center, as long as heat can be introduced into the interior of the heat shield 2.
[0069] Specifically, by providing a heat-transmitting hole, heat from the rice cooker can be introduced through the heat-transmitting hole into the heat-insulating cover located on one side of the support plate. Since the heat-insulating cover itself is made of a heat-insulating material, it can prevent the heat from being lost. Therefore, heat collection and heat preservation can be achieved. This structure can achieve rapid heat storage while preventing heat loss.
[0070] In this embodiment, the present invention further comprises: a heat conducting plate 4 , the heat insulating cover is buckled on the heat conducting plate, and the heat conducting element 5 is in contact with the heat conducting plate.
[0071] The heat transferred by the heat conducting element can be quickly absorbed by the heat conducting plate, thereby improving the heat collection capacity.
[0072] Specifically, there is no limitation on the material of the heat conducting plate itself, and the heat conducting plate is made of a material with a high thermal conductivity coefficient, such as copper, aluminum, iron, etc.
[0073] This embodiment further includes: a heat conducting element 5 connected to the heat conducting plate 4 via the heat conducting portion, with the other end acting on a side of the support plate 1 away from the heat insulation cover.
[0074] Specifically, when the heat conducting portion itself is a metal plate, the heat absorbed by the metal plate will be introduced into the heat conducting plate by heat conduction.
[0075] Preferably, when the heat conducting portion is a heat-transmitting hole 101 , one end of the heat conducting element 5 extends into the heat-transmitting hole 101 , and the other end acts on a side of the support plate away from the heat insulation cover.
[0076] The heat-conducting element 5 itself has a strong heat collection capability, thereby being able to quickly collect the heat radiated by the thermal insulation cover plate to avoid heat loss.
[0077] The structure of the heat conducting element 5 itself is not limited as long as it can achieve the heat conduction function. As a preferred embodiment, the heat conducting element 5 is configured with multiple radially arranged fins. At the same time, the heat conducting element 5 itself is made of a material with high thermal conductivity such as copper or aluminum.
[0078] In this embodiment, the method of attaching the heat conducting plate 4 to the support plate 1 is not limited; it can be secured in place by means of clips, glue, or ribs provided on the support plate 1. As a preferred embodiment, the heat conducting plate is provided with connection holes at locations corresponding to the heat-transmitting holes, through which screws are connected to the heat conducting element. Correspondingly, internal threads are provided in the connection holes and the heat-transmitting holes 10. In this embodiment, the screws primarily connect the heat conducting element to the heat conducting plate, thereby stabilizing the heat conducting element itself.
[0079] Furthermore, the screws themselves are made of metal. By arranging the screws, the heat absorbed by the heat-conducting element can be transferred to the heat-conducting plate, thereby playing a role of rapid heat conduction, thereby helping to achieve the overall heat preservation operation of the rice cooker lid.
[0080] Furthermore, the heat collecting fins 6 are provided on the heat conducting plate 4. The heat collecting fins 6 are provided on the heat conducting plate 4 to enable rapid heat collection. The heat collecting fins 6 can quickly absorb the heat collected by the heat conducting element itself, thereby accelerating the heat collection capability and preventing heat loss to the outside.
[0081] The shape of the heat-collecting fins 6 is not limited, as long as it can achieve heat collection. As an embodiment, the heat-collecting fins 6 themselves can be arranged radially. Specifically, any shape can be used as long as it can achieve rapid heat collection. In this embodiment, the heat-collecting fins 6 themselves are made of a material with a high thermal conductivity, such as copper or aluminum.
[0082] In the rice cooker cover provided in this embodiment, an air inlet 21 is provided on the heat insulation cover 2 , and an air outlet device 7 is provided inside the cover. The wind generated by the air outlet device 7 acts on the upstream of the air inlet 21 .
[0083] Specifically, the air outlet device 7 itself can generate cool air or normal temperature air, thereby facilitating the heat exchange operation.
[0084] Furthermore, an air inlet baffle 23 is provided at the air inlet 21, so as to control the air intake volume.
[0085] Through the combination of the air outlet device and the air inlet 21, the wind generated by the air outlet device can be directly introduced into the interior of the heat insulation cover 2, thereby quickly dissipating the heat inside the heat insulation cover.
[0086] Preferably, the heat shield 2 is provided with an air inlet 21 and an air outlet 22 , the air outlet 22 is provided with an air outlet baffle 24 , the air inlet 21 is provided with an air inlet baffle 23 , and the wind generated by the air outlet device 7 acts on the upstream of the air inlet 21 .
[0087] The specific location of the air outlet device is not limited. It can be set on the inner wall of the cover or on the inner cover. Preferably, the air outlet device is set on the support plate 1 and is arranged toward the air inlet 21. In this embodiment, the air outlet device itself includes a motor and a wind wheel arranged on the output shaft of the motor. The wind is generated by the rotation of the wind wheel to blow toward the air inlet 21.
[0088] In this embodiment, in addition to keeping food warm, it also allows for rapid heat dissipation. By providing an air inlet 21, an air outlet 22, and an air outlet device 7, when heat preservation is not required, the air inlet 21 and air outlet 22 are simply opened, and the air outlet device 7 is activated. This allows the heat collected in the heat shield to be quickly blown into the outside atmosphere. The combination of the heat shield and the air outlet device 7 allows for both rapid heat collection and rapid heat dissipation, thereby reducing the user's waiting time after food cooking is complete and improving the user experience.
[0089] In this embodiment, the air inlet baffle 23 and the air outlet baffle 24 are each provided with a driving member 8, which is adapted to drive the air inlet baffle 23 and the air outlet baffle 24 to open. The provision of the driving member 8 allows for orderly adjustment of the air inlet baffle 23 and the air outlet baffle 24, thereby adjusting the cooling rate and thus enhancing the intelligence of the electric pressure cooker.
[0090] Specifically, when the air inlet baffle 23 and the air outlet baffle 24 are simultaneously closed, the rice cooker lid can effectively insulate the rice cooker. When the air inlet baffle 23 and the air outlet baffle 24 are simultaneously opened, the rice cooker lid can quickly dissipate heat. When the air inlet baffle 23 and the air outlet baffle 24 are simultaneously half-opened, the heat dissipation duration can be extended. Similarly, by controlling the opening degrees of the air inlet baffle 23 and the air outlet baffle 24, different heat dissipation durations can be achieved, thereby enabling intelligent adjustment of the heat dissipation time.
[0091] For example, if the user sets the time to start eating 30 minutes after cooking, the air inlet baffle 23 and the air outlet baffle 24 can be controlled to open to a certain position at the same time, such as one-fifth. After 30 minutes, the food will cool down to the preset stable temperature, and the user can eat it directly, avoiding wasting time on cooling. In this way, the user can also perform remote control, making it easy to ensure that the food is stable and suitable for the user at the preset time.
[0092] In this embodiment, the opening method of the air inlet baffle 23 and the air outlet baffle 24 is not limited. As a preferred embodiment, the air inlet baffle 23 and / or the air outlet baffle 24 are provided with a rack structure 9, and the driving member 8 is provided with a gear that cooperates with the rack structure 9.
[0093] Specifically, the rack structure 9 can be used to control only the air inlet baffle 23, and the air outlet baffle 24 can be controlled by other structures; the rack structure 9 can be used to control only the air outlet baffle 24, and the air inlet baffle 23 can be controlled by other structures; and the rack structure 9 can also be used to control both the air inlet baffle 23 and the air outlet baffle 24 at the same time.
[0094] In this embodiment, the rack structure 9 is arranged on the top of the air inlet baffle 23 and / or the air outlet baffle 24 , a support platform 10 is provided on the support plate 1 , and the driving member 8 is provided on the support platform 10 .
[0095] To achieve longitudinal movement of the air outlet baffle 24 or the air inlet baffle 23, power must be applied to the upper or lower portion of the baffle. However, the gap below the baffle is small, making contact with the gear difficult. By placing the rack structure 9 at the top of the air outlet baffle 24 and / or the air inlet baffle 23, contact between the gear and the rack structure 9 can be facilitated. Furthermore, by providing a support platform 10, the gear can be positioned at the same height as the rack structure 9, thereby improving the stability of the connection between the gear and the rack structure 9.
[0096] In the rice cooker lid provided in this embodiment, the air outlet 22 and the air outlet 22 are provided with guide grooves 13, which extend along the movement direction of the air inlet baffle 23 and the air outlet baffle 24. This improves the stability of the air inlet baffle 23 and the air outlet baffle 24 during the opening and closing process.
[0097] Furthermore, the lengths of the air inlet baffle 23 and the air outlet baffle 24 are greater than the length of the guide groove.
[0098] The above arrangement allows the air inlet baffle 23 or the air outlet baffle 24 to be exposed outside the guide groove, while the gear can act on the rack structure 9 that is exposed from the guide groove. The above arrangement improves the connection stability between the gear and the rack, prevents the two from being directly dislodged, and ultimately improves the heat dissipation effect.
[0099] Specifically, if Figure 1 As shown, the left end of the air inlet baffle 23 is exposed to the outside of the guide groove.
[0100] In this embodiment, the heat collecting fins 6 are further provided with an air duct for air flow, and the air inlet 21 and the air outlet 22 are provided at both ends of the air duct. This arrangement can effectively improve the cooling efficiency of the heat collecting fins 6 themselves, thereby helping to control the cooling time.
[0101] In this embodiment, as a preferred implementation, the heat collecting fins 6 include: a linear fin 11, with its ends corresponding to the air inlet 21 and the air outlet 22, respectively; and two sets of streamlined fins 12, symmetrically arranged on either side of the linear fin 11. The combination of the linear fins 11 and the streamlined fins 12 effectively reduces the resistance experienced by the entire heat collecting fin 6 during the heat dissipation process, thereby improving the heat dissipation effect.
[0102] Specifically, the linear fins 11 themselves are arranged in a straight line. Figure 3 As shown, the streamlined fin 12 includes: an arc segment; a straight segment, which is symmetrically arranged at both ends of the arc segment, and the straight segment is arranged corresponding to the air inlet 21 and the air outlet 22.
[0103] By adopting the arc segment setting mode, the air flow resistance can be effectively reduced while the space occupied by the streamlined fins 12 themselves can be effectively reduced, and ultimately it can be beneficial to arrange other devices such as steam valves inside the rice cooker lid.
[0104] Example 2
[0105] This embodiment provides an electric pressure cooker, comprising:
[0106] The rice cooker lid provided in Example 1;
[0107] The rice cooker body is provided with the rice cooker cover rotatably arranged on the rice cooker body through a hinge part.
[0108] Furthermore, the rice cooker lid is provided with an air outlet 22, which is arranged toward the hinge portion. When a user operates the rice cooker lid, they usually need to press the side opposite the hinge portion. This arrangement prevents the air discharged through the air outlet 22 from directly blowing onto the user's hands during operation, thereby preventing heat burns to the user.
[0109] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
