Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, in particular to a rice cooker cover and an electric rice cooker. Background Art

[0002] Electric rice cookers are very common electrical appliances in daily life. They can use high-temperature steam to steam food.

[0003] In order to achieve the balance of the internal air pressure of the rice cooker, the rice cooker in the prior art is usually provided with a steam valve on the rice cooker cover. During the cooking process, the steam generated in the rice cooker is discharged to the outside through the steam valve.

[0004] However, the steam valve is usually installed in a fixed position on the rice cooker lid. During the cooking process, the position of the steam valve itself does not change. The exhaust volume of the steam valve itself is fixed. When the rice cooker itself is cooking at high power, the exhaust volume of the steam valve is insufficient, causing soup, porridge, and rice gruel to overflow. In the existing technology, the exhaust volume of the steam valve can be adjusted through different actuators. However, the steam valve and the actuator are usually integrated, making it difficult to disassemble and clean the steam valve, posing a hygiene hazard and reducing the user experience. Summary of the Invention

[0005] Therefore, the technical problem to be solved in the present invention is to overcome the defect that the steam valve of an electric rice cooker is difficult to clean in the prior art, thereby providing a rice cooker cover and an electric rice cooker.

[0006] The present invention provides a rice cooker cover, comprising: an air inlet channel, which is arranged on the rice cooker cover and passes through the rice cooker cover in a vertical direction;

[0019] The steering structure is arranged between the rotating seat and the executing structure, and is suitable for converting the rotation of the rotating seat into the linear motion of the executing structure.

[0020] The steering structure includes: a first chute, arranged on the inner wall of the rotating seat;

[0021] The second sliding groove is arranged on the outer wall of the push plate, and the first sliding groove is movably connected to the second sliding groove.

[0022] A protrusion is provided on the outer wall of the execution structure, and the second sliding groove is provided on the protrusion.

[0023] An extension portion is provided at the top end of the first sliding groove, and the extension portion is suitable for limiting the movement of the protrusion.

[0024] A limiting groove is provided on the outer circumference of the rotating seat. Along the rotation direction of the rotating seat, the two ends of the limiting groove correspond to the rising point and the descending point. The rice cooker cover is also provided with a limiting rib embedded in the limiting groove, and the limiting rib is suitable for contacting the rising point and the descending point.

[0025] A trigger protrusion is also provided on the rotating seat, and a micro switch that interacts with the protrusion is provided on the rice cooker cover. The micro switch is communicated with the power part. When the limit rib contacts the rising point, the protrusion triggers the micro switch.

[0026] The present invention also provides an electric rice cooker, comprising: the above-mentioned rice cooker cover;

[0027] The rice cooker body is provided with the rice cooker cover rotatably arranged in the rice cooker body.

[0028] The technical solution of the present invention has the following advantages:

[0029] 1. The present invention provides a rice cooker lid, comprising: an air inlet channel, which is arranged on the rice cooker lid and passes through the rice cooker lid in a vertical direction; a steam valve assembly, which is arranged on the air inlet channel and is suitable for adjusting the opening amplitude of the air inlet channel; an execution structure, which is arranged on one side of the steam valve assembly and is detachably connected to the steam valve assembly; a power member, which is connected to the execution structure and is suitable for driving the steam valve assembly to move up and down relative to the air inlet channel under the action of the power member.

[0030] By providing a power element, power is transmitted to the execution structure, driving the steam valve assembly connected to the execution structure to move up and down, thereby adjusting the opening range of the air inlet channel and controlling the exhaust volume of the steam valve on the rice cooker lid. This makes it difficult for the internal ingredients of the cooking device with this rice cooker lid to overflow from the steam valve after continuous high-power heating, thereby significantly improving the cooking speed. At the same time, the execution structure and the steam valve assembly are detachably connected, allowing the steam valve assembly to be removed from the execution structure. While the exhaust volume of the steam valve assembly can be adjusted, it is also convenient to disassemble and clean the steam valve assembly, overcoming the disadvantage of the existing technology that the steam valve of the rice cooker is difficult to clean.

[0031] 2. The present invention provides a rice cooker cover, wherein the steam valve assembly includes: a steam valve lower cover, which is provided with a plurality of accommodating holes suitable for accommodating and connecting the execution structure; and a steam valve upper cover, which is buckled and arranged on the steam valve lower cover.

[0032] This arrangement allows the user to easily remove the steam valve upper cover from the steam valve lower cover, thereby allowing the inside of the steam valve assembly and the steam valve upper cover to be fully cleaned.

[0033] 3. The rice cooker lid provided by the present invention has an execution structure including a guide column, which is arranged in a vertical direction and has a fixing piece provided on the circumference of the top end thereof, which is suitable for passing through the accommodating hole and being detachably connected to the accommodating hole.

[0034] The top end of the guide post is detachably connected to the receiving hole, so that the lower cover of the steam valve can be driven by the guide post and can also be removed from the guide post. Therefore, when cleaning is required, the user can remove the upper cover and the lower cover of the steam valve separately to achieve complete cleaning of the steam valve.

[0035] 4. In the rice cooker lid provided by the present invention, the fixing piece is elastically arranged and sleeved on the guide post, and a plurality of annular ribs are arranged on the inner side thereof, and the annular ribs abut against the guide post.

[0036] The provision of multiple annular ribs further increases the connection strength between the guide post and the fixing piece.

[0037] 5. The present invention provides a rice cooker lid, wherein a flange structure is provided on the peripheral side of the fixing member, and the inner side surface of the accommodating hole protruding from the lower cover of the steam valve is provided with a positioning rib, and the flange structure is sleeved on the positioning rib.

[0038] The fixing piece is elastically arranged, and the flange structure is sleeved on the positioning rib of the accommodating hole, so that the fixing piece can be reliably fixed between the steam valve upper cover and the steam valve lower cover.

[0039] 5. In the rice cooker lid provided by the present invention, the top surface of the fixing member abuts against the steam valve upper cover.

[0040] This arrangement allows the guide column with the fixing part to simultaneously drive the steam valve upper cover and the steam valve lower cover during the lifting process, ensuring that the steam valve is evenly stressed and at the same time limiting the fixing part to prevent the fixing part from shaking in the steam valve assembly.

[0041] 6. The present invention provides a rice cooker lid, wherein the steering structure includes: a first slide groove, which is arranged on the inner wall of the rotating seat; and a second slide groove, which is arranged on the outer wall of the push plate, and the first slide groove is movably connected to the second slide groove.

[0042] Through the combination of the first and second chutes, when the rotating base starts rotating, the first chutes can support the second chutes themselves, thereby achieving the lifting and lowering of the actuator structure. At the same time, because the chutes and the guideway are connected between the inner wall of the rotating base and the outer wall of the actuator structure, the overall structure is relatively compact.

[0043] 7. In the rice cooker lid provided by the present invention, a protrusion is provided on the outer wall of the execution structure, and the second sliding groove is provided on the protrusion.

[0044] By providing the protrusion, the extension degree of the execution structure toward the rotating seat can be increased, thereby improving the connection stability of the first sliding groove thereon.

[0045] 8. In the rice cooker cover provided by the present invention, an extension portion is provided at the top end of the first sliding groove, and the extension portion is suitable for limiting the movement of the protrusion.

[0046] When the protrusion comes into contact with the extension portion, the extension portion can limit further movement of the protrusion on the slide groove, thereby preventing the rotating seat and the push plate assembly from coming out relative to each other.

[0047] 9. The present invention provides a rice cooker cover, wherein a limiting groove is provided on the outer circumference of the rotating seat, and along the rotation direction of the rotating seat, the two ends of the limiting groove correspond to a rising point and a descending point. The rice cooker cover is also provided with a limiting rib embedded in the limiting groove, and the limiting rib is suitable for contacting the rising point and the descending point.

[0048] The combination of the limiting groove and the limiting rib can limit the rotation of the rotating seat within a limited range, thereby preventing the rotating seat from rotating excessively and causing the execution structure to disengage from the rotating seat.

[0058] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0059] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0060] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0061] 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.

[0062] like Figures 1-6 As shown, this embodiment provides a rice cooker lid, including an air inlet channel 1, a steam valve assembly, a structure and a power part 8.

[0063] The air inlet channel 1 is arranged on the middle part of the rice cooker cover and passes through the rice cooker cover in a vertical direction. The lower section of the air inlet channel 1 is arranged in a cylindrical shape, and the inner diameter of the upper section gradually increases.

[0064] The steam valve assembly is buckled on the upper section of the air intake channel 1 and can adjust the opening amplitude of the air intake channel 1.

[0065] The execution structure is arranged on one side of the steam valve assembly and is detachably connected to the steam valve assembly. In this embodiment, part of the execution structure passes through the upper section of the air inlet channel 1 and is connected to the steam valve assembly.

[0066] The power part 8 is connected to the execution structure. Under the action of the power part 8, the execution structure can drive the steam valve assembly to move up and down relative to the air inlet channel 1. In this embodiment, the power part 8 is a driving motor, and it can also be an electric push rod or cylinder part with a power supply.

[0067] By providing a power member 8, power is transmitted to the execution structure, driving the steam valve assembly connected to the execution structure to move up and down, thereby adjusting the opening range of the air inlet channel 1 and controlling the exhaust volume of the steam valve on the rice cooker lid. This makes it difficult for the cooking device with this rice cooker lid to overflow from the steam valve even after continuous high-power heating, thereby significantly increasing the cooking speed. At the same time, the execution structure and the steam valve assembly are detachably connected, allowing the steam valve assembly to be removed from the execution structure. While the exhaust volume of the steam valve assembly can be adjusted, it is also convenient to disassemble and clean the steam valve assembly, overcoming the disadvantage of the existing technology that the steam valve of the rice cooker is difficult to clean.

[0068] like Figure 2 and Figure 5 As shown, the steam valve assembly includes a dome-shaped upper steam valve cover 2 and a lower steam valve cover 3. The edge of the upper steam valve cover 2 snaps onto the outside of the lower steam valve cover 3. The lower steam valve cover 3 is evenly distributed with a number of receiving holes 31 to accommodate and connect the actuator. This arrangement allows the user to easily remove the upper steam valve cover 2 from the lower steam valve cover 3, allowing for thorough cleaning of the interior of the steam valve assembly and the upper steam valve cover 2.

[0069] The actuator structure includes a guide post 4 made of metal and arranged in a vertical direction. An annular fixing member 5 is provided around the top of the guide post 4. The guide post 4 partially passes through the receiving hole 31 and is detachably connected to the receiving hole 31. The top of the guide post 4 is detachably connected to the receiving hole 31, so that the steam valve lower cover 3 can be driven by the guide post 4 while also being removed from the guide post 4. When cleaning is required, the user can remove the steam valve upper cover 2 and the steam valve lower cover 3 separately, achieving complete cleaning of the steam valve.

[0070] The fixing member 5 is elastically configured, specifically as a silicone member, but can also be made of other elastic materials such as a rubber composite. It is sleeved onto the guide post 4 and has several protruding annular ribs 51 on its inner side, which abut against the guide post 4. The provision of multiple annular ribs 51 further strengthens the connection between the guide post 4 and the fixing member 5. As an alternative embodiment, the annular ribs 51 can also be omitted, and the fixing member 5 and the guide post 4 can be connected by an interference fit.

[0071] like Figure 6 As shown, the fixing member 5 is provided with a partially arcuate flange structure 52 on its periphery. The inner side of the receiving hole 31 protruding from the steam valve lower cover 3 is provided with a positioning rib 311, and the flange structure 52 is mounted on the positioning rib 311. The fixing member 5 is elastic, and the flange structure 52 is mounted on the positioning rib 311 of the receiving hole 31, which can reliably fix the fixing member 5 between the steam valve upper cover 2 and the steam valve lower cover 3.

[0072] In addition, the top surface of the fixing member 5 abuts against the steam valve upper cover 2. This arrangement allows the guide pillar 4 with the fixing member 5 to simultaneously drive the steam valve upper cover 2 and the steam valve lower cover 3 during the lifting process, ensuring uniform force on the steam valve and limiting the fixing member 5 to prevent it from shaking inside the steam valve assembly.

[0073] The execution structure further includes an annular push plate 6, which is arranged on the lower side of the guide column 4 and can support the guide column 4. The push plate 6 is also provided with a second sliding groove.

[0074] The rice cooker cover also includes a transmission device that can connect the power member 8 and the execution structure. The transmission device includes a rotating seat 7 and a steering structure.

[0075] The execution structure is arranged inside the rotating seat 7, a rack is provided on the outer wall of the rotating seat 7, a gear 81 is provided at the output end of the power member 8, the gear 81 acts on the rack, and the steering structure is also arranged between the rotating seat 7 and the execution structure, which is suitable for converting the rotation of the rotating seat 7 into linear motion of the execution structure.

[0076] The steering structure includes a first chute and a second chute. The first chute is arranged on the inner wall of the rotating seat 7; the second chute is arranged on the outer wall of the push plate 6. The first chute and the second chute are interlocked and movably connected.

[0077] Through the combination of the first and second chutes, when the rotating base 7 starts to rotate, the first chutes can support the second chutes themselves, thereby achieving the lifting and lowering of the actuator structure. At the same time, because the chutes and the guideways are connected between the inner wall of the rotating base 7 and the outer wall of the actuator structure, the overall structure is relatively compact.

[0078] The outer wall of the execution structure is provided with a protrusion, and the second chute is provided on the protrusion. By providing the protrusion, the extension degree of the execution structure toward the rotating seat 7 can be increased, thereby improving the connection stability of the first chute thereon.

[0079] The top of the first chute is provided with an extension portion, which is suitable for limiting the movement of the projection. When the projection contacts the extension portion, the extension portion can limit the further movement of the projection on the chute, thereby preventing relative disengagement between the rotating seat 7 and the push plate 6 assembly.

[0080] A limiting groove is provided on the outer circumference of the rotating seat 7. Along the rotation direction of the rotating seat 7, the two ends of the limiting groove correspond to the rising point and the descending point. The rice cooker cover is also provided with a limiting retaining rib embedded in the limiting groove, and the limiting retaining rib is suitable for contacting the rising point and the descending point. Through the combination of the limiting groove and the limiting retaining rib, the rotating seat 7 can be restricted from rotating within a limited range, thereby preventing the rotating seat 7 from rotating excessively and causing the execution structure and the rotating seat 7 to escape. A triggering protrusion is also provided on the rotating seat 7, and a micro switch that interacts with the triggering protrusion is provided on the surface cover of the rice cooker cover. The micro switch is in communication connection with the power part 8. When the limiting retaining rib contacts the rising point, the triggering protrusion triggers the micro switch.

[0081] The present invention also provides an electric rice cooker, comprising the rice cooker cover and a cooker body, wherein the rice cooker cover is rotatably arranged in the cooker body.

[0082] 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 appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications derived therefrom remain within the scope of protection of the present invention.
