Technical Field
[0001] The present invention relates to the technical field of electrical equipment, and in particular to a positioning structure and a cooking device. Background Art
[0002] Cooking devices such as rice cookers on the market consist of an inner pot and a heating plate (also known as a coiled plate or heating plate). The inner pot is placed on the heating plate to cook food. When the inner pot is placed on the heating plate, it can easily tilt, resulting in poor contact between the inner pot and the heating plate, affecting the cooking effect.
[0003] To this end, the prior art calibrates the position of the inner pot by providing a plurality of positioning bumps on the inner wall of the heating plate. However, such positioning bumps can only position the inner pot of one size, and have poor versatility and cannot meet the needs of product diversification. Summary of the Invention

[0066] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.
[0067] Currently, the anti-misalignment structure of the inner pot of a cooking device is to set multiple positioning bumps on the inner wall of the heating plate to correct the position of the inner pot. However, the length of the positioning bumps protruding from the inner wall of the heating plate is fixed. Therefore, positioning bumps of one length can only position the inner pot of one size, which cannot meet the assembly requirements of inner pots of two or more sizes and heating plates. The poor versatility affects the diversified design of products. Moreover, for products where the outer wall of the inner pot is far away from the inner wall of the heating plate, the positioning bumps are too long, affecting the appearance of the inner wall of the heating plate and failing to meet product requirements.
[0068] Based on this, the present invention provides a positioning structure and a cooking device with good versatility and capable of meeting the diverse needs of products.
[0069] The following combination Figure 1-Figure 5 , describing embodiments of the positioning structure and cooking device of the present invention.
[0070] According to an embodiment of the present invention, in a first aspect, a positioning structure is provided, which is applied to a cooking device. The cooking device includes a heating plate 1 and an inner pot 2. The inner pot 2 is arranged in the heating plate 1 through the positioning structure. The positioning structure includes: a pressure rod assembly and a positioning assembly. The pressure rod assembly is arranged on the outer wall of the heating plate 1. The pressure rod assembly has a first position when it is not under force and a second position under the pressure of the inner pot 2. The positioning assembly is telescopically arranged on the side wall of the heating plate 1. The positioning assembly includes a driving end 301 and a positioning end 302. The driving end 301 is connected to the pressure rod assembly. The positioning assembly has an extended position and a retracted position. When the pressure rod assembly moves from the first position to the second position, it drives the positioning assembly to move from the retracted position to the extended position. When the positioning assembly is in the extended position, the positioning end 302 abuts against the outer wall of the inner pot 2. The length of the positioning assembly extending from the side wall of the heating plate 1 is adjustable.
[0071] In this positioning structure, when the pressure rod assembly moves from the first position to the second position, it can drive the positioning assembly to move from the retracted position to the extended position. When the positioning assembly is in the extended position, its positioning end 302 abuts the outer wall of the inner pot 2, thereby positioning the inner pot 2 and preventing the inner pot 2 from shifting. This ensures good contact between the inner pot 2 and the heating plate 1, ensuring the cooking effect. Moreover, the distance between the outer wall of the inner pot 2 and the inner wall of the heating plate 1 varies depending on the size of the inner pot 2. The length of the positioning assembly extending from the side wall of the heating plate 1 of this positioning structure is adjustable, allowing it to position inner pots 2 of different sizes and sizes, significantly improving the versatility of the positioning structure and meeting the needs of product diversification.
[0072] like Figure 1 As shown, the positioning structure of this embodiment is applied to a cooking device, such as an electric rice cooker or an electric pressure cooker. The cooking device includes a heating plate 1 and an inner pot 2. The heating plate 1 and the inner pot 2 are the core structure of the cooking device, and the two work together to realize cooking functions, such as cooking rice. The heating plate 1 has built-in electric heating tubes and spiral heating wires. When the heating plate 1 is powered on, it can convert electrical energy into thermal energy. The inner pot 2 can be placed in the heating plate 1. The interior of the inner pot 2 is in direct contact with the food. The inner pot 2 is heated by the bottom and conducts heat to the food to achieve cooking of the food.
[0073] The inner pot 2 is positioned within the heating plate 1 using the positioning structure of this embodiment. The positioning structure includes a pressure rod assembly and a positioning assembly. The pressure rod assembly is positioned on the outer wall of the heating plate 1 and does not occupy the internal space of the heating plate 1. The pressure rod assembly can move under the pressure of the inner pot 2. Specifically, when the pressure assembly is not subjected to pressure from the inner pot 2, the pressure rod assembly is in a first position. When the inner pot 2 is installed in the heating plate 1, the inner pot 2 applies pressure to the pressure rod assembly, causing the pressure rod assembly to move from the first position to the second position.
[0074] It should be noted that in this embodiment, the direction of the pressure applied by the inner pot 2 to the pressure assembly is consistent with the direction of gravity, that is, the pressure is downward. The top edge of the inner pot 2 is turned outward, and the turned-out edge can apply downward pressure to the positioning assembly.
[0075] The positioning assembly is telescopically arranged on the side wall of the heating plate 1, that is, the positioning assembly can extend from the side wall of the heating plate 1, or can be retracted into the side wall of the heating plate 1. The positioning assembly includes a driving end 301 and a positioning end 302. When the positioning assembly extends from the side wall of the heating plate 1, the positioning end 302 of the positioning assembly can abut against the outer wall of the inner pot 2 to position the inner pot 2. When the positioning assembly is retracted into the side wall of the heating plate 1, the positioning assembly is hidden in the side wall of the heating plate 1. The driving end 301 is connected to the pressure rod assembly. When the inner pot 2 applies downward pressure to the pressure rod assembly, the pressure rod assembly moves from the first position to the second position, and at the same time drives the positioning assembly to move from the retracted position to the extended position. In addition, the length of the positioning assembly extending from the side wall of the heating plate 1 is adjustable to position inner pots 2 of different models and sizes, thereby improving the versatility of the positioning structure and meeting the needs of product diversification.
[0076] Furthermore, the pressure rod assembly includes a force-bearing end 401, a force-transmitting end 402 and an adjusting member 5. The pressure of the inner pot 2 acts on the force-bearing end 401, the force-transmitting end 402 is connected to the driving end 301, and the adjusting member 5 is arranged between the force-bearing end 401 and the force-transmitting end 402. The adjusting member 5 adjusts the moving distance of the force-transmitting end 402 from the first position to the second position.
[0077] like Figure 1 As shown, the pressure rod assembly includes a force-bearing end 401, a force-transmitting end 402 and an adjusting member 5, wherein the force-bearing end 401 is used to bear the pressure applied by the inner pot 2, that is, the pressure of the inner pot 2 on the pressure rod assembly acts on the force-bearing end 401, and the force-transmitting end 402 is connected to the driving end 301, so that when the pressure assembly moves from the first position to the second position, the positioning assembly is driven to move from the retracted position to the extended position.
[0078] The adjusting member 5 is disposed between the force-receiving end 401 and the force-transmitting end 402, so that the moving distance of the force-receiving end 401 from the first position to the second position is at least partially transmitted to the force-transmitting end 402. For example, under the pressure of the inner pot 2, the moving distance L1 of the force-receiving end 401 from the first position to the second position is the force-transmitting end 402, and the moving distance L2 of the force-transmitting end 402 from the first position to the second position is related to the moving distance of the positioning assembly from the retracted position to the extended position, and the moving distance of the positioning assembly from the retracted position to the extended position is related to the distance from the outer wall of the inner pot 2 to the inner wall of the heating plate 1. When the distance from the outer wall of the inner pot 2 to the inner wall of the heating plate 1 is closer, the moving distance of the positioning assembly from the retracted position to the extended position is smaller, and the moving distance L2 of the force transmission end 402 from the first position to the second position is smaller; when the distance from the outer wall of the inner pot 2 to the inner wall of the heating plate 1 is farther, the moving distance of the positioning assembly from the retracted position to the extended position is larger, and the moving distance L2 of the force transmission end 402 from the first position to the second position is larger.
[0079] That is to say, when the inner pot 2 is installed into the heating plate 1, the pressure rod assembly moves from the first position to the second position, the force-bearing end 401 moves from the first position to the second position, and the moving distance of the force-transmitting end 402 from the first position to the second position will be affected by the distance from the outer wall of the inner pot 2 to the inner wall of the heating plate 1.
[0080] While the distance the force-receiving end 401 moves from the first position to the second position remains constant, the adjusting member 5 can adjust the distance L2 that the force-transmitting end 402 moves from the first position to the second position, thereby achieving the purpose of adjusting the length of the positioning assembly extending from the side wall of the heating plate 1 to position inner pots 2 of different sizes. This pressure rod assembly has a relatively simple structure and is stable and reliable, allowing the positioning structure to position inner pots of the same model and size, thereby improving the versatility of the positioning structure.
[0081] Furthermore, the force transmission end 402 and the driving end 301 are slidingly connected via an inclined surface structure.
[0082] The force-transmitting end 402 is connected to the driving end 301. The two ends are slidably connected via an inclined surface structure. The relative sliding of the force-transmitting end 402 and the driving end 301 allows the pressure assembly to move from the retracted position to the extended position when the pressure assembly moves from the first position to the second position. This connection between the force-transmitting end 402 and the driving end 301 occupies little space, offers a compact and reasonable structure, and does not increase the product size, thereby fully utilizing the installation space and improving space efficiency.
[0083] Furthermore, the inclined surface structure includes a first surface 601 and a second surface 602 , one of which is the end surface of the force transmission end 402 , and the other is the end surface of the driving end 301 , and the first surface 601 and the second surface 602 are in sliding contact.
[0084] like Figure 2 As shown, the inclined surface structure includes a first surface 601 and a second surface 602. The first surface 601 and the second surface 602 cooperate with each other. One of the first surface 601 and the second surface 602 is the end surface of the force transmission end 402, and the other is the end surface of the driving end 301. In this embodiment, the first surface 601 is the end surface of the force transmission end 402, and the second surface 602 is the end surface of the driving end 301. The first surface 601 and the second surface 602 are in sliding contact. The areas of the first surface 601 and the second surface 602 match each other to ensure stable cooperation.
[0085] When the pressure rod assembly moves from the first position to the second position, the first surface 601 moves from the first position to the second position along with the force transmission end 402, the first surface 601 slides relative to the second surface 602, and the first surface 601 applies a force to the second surface 602 to move toward the extended position, causing the positioning assembly to move from the retracted position to the extended position.
[0086] In other embodiments, the first surface 601 may also be the end surface of the driving end 301 , and the second surface 602 may be the end surface of the force transmission end 402 , as long as the first surface 601 and the second surface 602 can be slidably matched.
[0087] Furthermore, the extending direction of the inclined surface structure and the moving direction of the pressure rod assembly are arranged at an angle, and the angle α is ≤ 90°.
[0088] In this embodiment, the top of the heating plate 1 is an open end, and the inner pot 2 is loaded into the heating plate 1 from top to bottom. The inner pot 2 applies downward pressure to the force-bearing end 401 of the pressure rod assembly. The moving direction of the pressure assembly is as follows: Figure 2 The direction indicated by the arrow x-x' is the vertical direction.
[0089] The extension direction of the inclined structure is set at an angle to the moving direction of the pressure rod assembly, and the angle α is ≤ 90°, so that the pressure rod assembly and the positioning assembly are closer, the structure is more compact, the setting space is saved, the utilization rate of the setting space is improved, and it is beneficial to improve the transmission efficiency of the force.
[0090] For example, the angle α may be 90°, 80°, 60°, 45°, etc.
[0091] Furthermore, the pressure rod assembly also includes a push rod 7 and a transmission rod 8. The end of the push rod 7 away from the transmission rod 8 is a force-bearing end 401, and the end of the transmission rod 8 away from the push rod 7 is a force-transmitting end 402. The other end of the push rod 7 is connected to the other end of the transmission rod 8 through an adjusting member 5.
[0092] like Figure 1 As shown, the pressure rod assembly also includes a push rod 7 and a transmission rod 8. The push rod 7 is located above the transmission rod 8. The end of the push rod 7 away from the transmission rod 8 is a force-bearing end 401, and the end of the transmission rod 8 away from the push rod 7 is a force-transmitting end 402. The other end of the push rod 7 is connected to the other end of the transmission rod 8 through an adjusting member 5, that is, the opposite ends of the push rod 7 and the transmission rod 8 are connected through the adjusting member 5.
[0093] Specifically, the push rod 7 and the transmission rod 8 are both arranged in a vertical direction, and the adjustment member 5 is disposed between the push rod 7 and the transmission rod 8. The adjustment member 5 can effectively adjust the distance of the transmission rod 8 from the first position (transmission rod first position) to the second position (transmission rod second position) based on the distance of the push rod 7 from the first position (the push rod first position) to the second position (the push rod second position) and the distance between the outer wall of the inner pot 2 and the inner wall of the heating plate 1. The distance of the push rod 7 from the first position (the push rod first position) to the second position (the push rod second position) is at least partially transmitted to the transmission rod 8. The distance of the transmission rod 8 from the first position (transmission rod first position) to the second position (transmission rod second position) has a certain adjustment margin based on the distance of the push rod 7 from the first position (the push rod first position) to the second position (the push rod second position), so as to accommodate inner pots of different models and sizes and achieve positioning of inner pots of different sizes.
[0094] In this embodiment, the adjusting member 5 is an elastic member, specifically a spring. When the inner pot 2 presses down the push rod 7, and the push rod 7 moves from its first position to its second position, the adjusting member 5 is compressed, and the pressure is transmitted to the transmission rod 8, causing the transmission rod 8 to move from its first position to its second position.
[0095] It should be noted that the first position and the second position are different for different structural parts. For example, the first position and the second position of the push rod 7 are its own first position and second position, that is, the push rod first position and the push rod second position, which are different from the transmission rod first position and the transmission rod second position of the transmission rod 8.
[0096] In this embodiment, a fixing bracket 103 is provided on the outer wall of the heating plate 1. This fixing bracket 103 can be integrally formed with the heating plate 1. A through-hole is formed inside the fixing bracket 103, through which the transmission rod 8 is inserted. The through-hole is axially arranged in the vertical direction, and the transmission rod 8 can move vertically within the through-hole. The provision of the fixing bracket 103 can further stabilize the position of the transmission rod 8, preventing the transmission rod 8 from shaking during movement. The through-hole also serves as a guide for the transmission rod 8, improving the reliability of the structure.
[0097] Furthermore, the cooking device further includes a base, and the pressure rod assembly further includes a support ring 10, which is arranged on the base. The support ring 10 is provided with a through hole, and the top rod 7 is passed through the through hole.
[0098] like Figure 4 As shown, the cooking device also includes a base, and the pressure rod assembly also includes a support ring 10. The support ring 10 is an annular structure. The bottom of the support ring 10 is connected to the base. The support ring 10 and the base together form an installation cavity, and the heating plate 1 is arranged in the installation cavity.
[0099] The support ring 10 is provided with a through hole, the axial direction of which is aligned with the movement direction of the compression rod assembly. In this embodiment, the axial direction of the through hole is vertical. The push rod 7 is disposed in the through hole and can move up and down in the vertical direction within the through hole to achieve reciprocating movement of the push rod 7 between a first position and a second position.
[0100] Furthermore, the positioning structure also includes a limiting mechanism, which is provided on the push rod 7 and the support ring 10 , and the limiting mechanism is used to limit the moving distance of the push rod 7 .
[0101] The positioning structure also includes a limiting mechanism, which is used to limit the movement distance of the push rod 7 under the pressure of the inner pot 2, prevent the push rod 7 from excessive movement and departure from its second position, improve structural reliability, and prevent failure of the positioning structure due to accidental touch operation.
[0102] The pressure rod assembly can move from the first position to the second position under the action of an external force. This external force can be the downward pressure applied by the inner pot 2 on the pressure rod assembly, or it can be the downward pressure applied by the user due to improper operation. Due to the design of the inner pot 2 and the heating plate 1, when the inner pot 2 applies downward pressure on the pressure rod assembly, the pressure rod assembly will stop moving after moving from the first position to the second position. However, if the user improperly operates and causes the pressure rod assembly to move from the first position, it is easy to cause the pressure rod assembly to move excessively, causing the push rod 7 to move excessively and move out of its second position, resulting in the first surface 601 and the second surface 602 being disengaged and separated, and the positioning structure to fail.
[0103] Therefore, the positioning structure of this embodiment includes a limiting mechanism, which is arranged on the top rod 7 and the support ring 10. If the user mistakenly operates the pressure rod assembly to move from the first position, the limiting mechanism will limit the moving distance of the top rod 7, thereby preventing the pressure rod assembly from excessive movement and causing the first surface 601 and the second surface 602 to disengage, thereby improving structural reliability.
[0104] Furthermore, the limiting mechanism includes a limiting protrusion 9 , which is provided on the outer wall of the push rod 7 . When the push rod 7 is located at the second position, the limiting protrusion 9 abuts against the upper surface of the support ring 10 .
[0105] The limiting mechanism includes a limiting protrusion 9, which is provided on the outer wall of the push rod 7. The limiting protrusion 9 protrudes from the outer wall of the push rod 7. When the push rod 7 is in the second position, the limiting protrusion 9 abuts against the upper surface of the support ring 10, preventing the push rod 7 from further moving in the through hole when it reaches the second position, thereby preventing the first surface 601 and the second surface 602 from disengaging, thereby improving structural reliability. Moreover, the limiting mechanism is relatively simple in structure, easy to set up, and does not occupy too much installation space.
[0106] Furthermore, when the positioning assembly is in the retracted position, the end surface of the positioning end 302 is flush with the inner wall of the heating plate 1 .
[0107] like Figure 1 As shown, when the inner pot 2 is not installed in the heating plate 1 and the positioning component is in the retracted position, the end face of the positioning end 302 is flush with the inner wall of the heating plate 1, and the positioning end 302 does not protrude from the inner wall of the heating plate 1. The positioning component is hidden in the side wall of the heating plate 1, thereby achieving the purpose of hiding the positioning structure and making the inner wall of the heating plate smooth and beautiful in appearance.
[0108] In this embodiment, the positioning end 302 is provided with an elastic pad 14. The positioning end 302 abuts the outer wall of the inner pot 2 via the elastic pad 14. The elastic pad 14 is made of an elastic material, such as rubber. The provision of the elastic pad 14 on the positioning end 302 eliminates any noise that might be produced by the positioning end 302 abutting the outer wall of the inner pot 2. Furthermore, the positioning end 302 is more closely attached to the outer wall of the inner pot 2, improving the positioning effect and correcting any misalignment of the inner pot 2.
[0109] Furthermore, the positioning assembly also includes a positioning rod 11 and a reset member 12. One end of the positioning rod 11 is a driving end 301, and the other end is a positioning end 302. The positioning rod 11 is limited to the side wall of the heating plate 1. One end of the reset member 12 is connected to the positioning rod 11, and the other end is connected to the side wall of the heating plate 1. The reset member 12 drives the positioning rod 11 to move from the extended position to the retracted position.
[0110] like Figure 1-Figure 2As shown, the positioning assembly further includes a positioning rod 11 and a reset member 12. One end of the positioning rod 11 is a driving end 301, and the other end is a positioning end 302. The positioning rod 11 is arranged along the telescopic direction of the positioning assembly. Figure 2 In the process of extension and contraction of the positioning assembly, the positioning rod 11 is limited to the side wall of the heating plate 1, and the positioning rod 11 will not fall off the side wall of the heating plate 1 to ensure the reliability of the structure.
[0111] The return member 12 is an elastic member, specifically a return spring. One end of the return member 12 is connected to the positioning rod 11, and the other end is connected to the side wall of the heating plate 1. The return member 12 drives the positioning rod 11 from the extended position to the retracted position. When the positioning rod 11 moves from the retracted position to the extended position, the return spring compresses. When the downward pressure of the inner pot 2 on the pressure rod assembly disappears, the positioning rod 11 moves from the extended position to the retracted position under the restoring force of the return member 12.
[0112] Furthermore, the side wall of the heating plate 1 is provided with an assembly column 101 , which has an assembly hole 102 therein, and the positioning rod 11 is passed through the assembly hole 102 , and the positioning rod 11 is limited in the assembly hole 102 by a snap-fit mechanism.
[0113] like Figure 1-Figure 2 As shown, a mounting post 101 is provided on the side wall of the heating plate 1. The mounting post 101 protrudes from the side wall of the heating plate 1. The mounting post 101 defines a mounting hole 102. The positioning rod 11 is inserted into the mounting hole 102. The axial direction of the mounting hole 102 aligns with the extension and retraction direction of the positioning rod 11. During the extension and retraction process of the positioning rod 11, the positioning rod 11 is at least partially located within the mounting hole 102.
[0114] The positioning rod 11 is limited in the assembly hole 102 by the clamping mechanism, so that the assembly hole 102 can guide the positioning rod 11 and prevent the positioning assembly from falling off the side wall of the heating plate 1, thereby improving structural reliability.
[0115] Furthermore, the snap-fit mechanism includes a snap 1301 and a base 1302. The snap 1301 is arranged on the inner wall of the assembly hole 102 away from the inner pot 2, and the base 1302 is arranged on the outer wall of the positioning rod 11. When the positioning rod 11 is in the retracted position, the snap 1301 is snap-fitted with the base 1302.
[0116] like Figure 2As shown, the locking mechanism includes a buckle 1301 and a base 1302. The buckle 1301 and the base 1302 can be engaged with each other to achieve the position limiting of the assembly hole 102 on the positioning rod 11. The buckle 1301 is arranged on the inner wall of the assembly hole 102 away from the inner pot 2, that is, the buckle 1301 is arranged at the end of the assembly hole 102 away from the inner pot 2, and the buckle 1301 is placed on the inner wall of this end. The base 1302 is arranged on the outer wall of the positioning rod 11, and the base 1302 protrudes from the outer wall of the positioning rod 11. When the positioning rod 11 is in the retracted position, the buckle 1301 and the base 1302 are engaged to prevent the positioning rod 11 from falling out of the assembly hole 102, thereby improving the reliability of the structure.
[0117] Furthermore, one end of the assembly hole 102 close to the inner pot 2 has a step, and one end of the reset member 12 abuts against the side of the clamping platform 1302 facing away from the buckle 1301, and the other end abuts against the step.
[0118] like Figure 2 As shown, the end of the assembly hole 102 near the inner pot 2 has a step that protrudes from the inner wall of the assembly hole. One end of the reset member 12 abuts the side of the retaining plate 1302 facing away from the buckle 1301, while the other end abuts the step. When the positioning rod 11 moves from the retracted position to the extended position, the retaining plate 1302 and the step constrain the reset member 12, causing it to be compressed. This arrangement of the reset member 12 fully utilizes the installation space, resulting in a compact structure and improved space utilization.
[0119] Furthermore, the moving distance of the push rod 7 from the first position to the second position is greater than or equal to the moving distance of the positioning rod 11 from the retracted position to the extended position.
[0120] In this embodiment, the positioning structure can accurately position inner pots 2 of different sizes and models. Under the downward pressure of the inner pot 2, the distance that the push rod 7 moves from the first position to the second position is greater than or equal to the distance that the positioning rod 11 moves from the retracted position to the extended position. This allows for an adjustable distance between the retracted and extended positions of the positioning rod 11 to accommodate inner pots of different sizes and models, achieving accurate positioning of inner pots of varying sizes.
[0121] Specifically, when the inner pot 2 applies downward pressure to the force-transmitting end 401 of the push rod 7, the push rod 7 moves a distance L1 from its first position to its second position, the transmission rod 8 moves a distance L2 from its first position to its second position, and the positioning rod 11 moves a distance L3 from its retracted position to its extended position. L1 ≥ L2, and L1 ≥ L3. Because the adjusting member 5 can adjust the distance L2 of the force-transmitting end 402 from the first position to the second position, the force-transmitting end 402 drives the positioning rod 11 from the retracted position to the extended position, thereby adjusting the distance L3 of the positioning rod 11 from the retracted position to the extended position. The distance L3 of the positioning rod 11 from the retracted position to the extended position is the length that the positioning end 302 of the positioning rod 11 extends from the inner wall of the inner pot 2, thereby achieving calibrated positioning of inner pots 2 of different sizes. This pressure rod assembly has a relatively simple structure and is stable and reliable, enabling the positioning structure to position inner pots 2 of the same size and model, improving the versatility of the positioning structure.
[0122] This embodiment further provides a cooking device, comprising a heating plate 1 and an inner pot 2. The inner pot 2 is disposed in the heating plate 1 by the above-mentioned positioning structure.
[0123] The cooking device comprises a heating plate 1 and an inner pot 2. The heating plate 1 and inner pot 2 are the core components of the cooking device, and the two work together to achieve cooking functions, such as cooking rice. The heating plate 1 has built-in electric heating tubes and spiral heating wires. When powered, the heating plate 1 converts electrical energy into thermal energy. The inner pot 2 can be placed within the heating plate 1. The interior of the inner pot 2 directly contacts the food. The inner pot 2 is heated from the bottom, and the heat is transferred to the food to achieve cooking.
[0124] The inner pot 2 is positioned within the heating plate 1 by the positioning structure of this embodiment, preventing the inner pot 2 from shifting when placed in the heating plate 1. This ensures good contact between the inner pot 2 and the heating plate 1, ensuring the best cooking effect. The heating plate 1 of this cooking device can accommodate inner pots 2 of different sizes and models. The distance between the outer wall of each inner pot 2 and the inner wall of the heating plate 1 varies. The positioning assembly of this embodiment extends to an adjustable length from the side wall of the heating plate 1, allowing it to position inner pots 2 of different sizes and models, thereby improving the versatility of the positioning structure and meeting the needs of product diversification.
[0125] The number of positioning structures can be multiple groups, and the multiple groups of positioning structures are arranged at intervals along the circumference of the heating plate 1. Figure 3 As shown, in this embodiment, three groups of positioning structures are provided, and the three groups of positioning structures are evenly spaced along the circumference of the heating plate 1 .
[0126] The cooking device can be an electric rice cooker or an electric pressure cooker. In this embodiment, the cooking device is an electric rice cooker. The electric rice cooker also includes a base. The support ring 10 of the pressure rod assembly in the positioning structure and the base together form an installation cavity, and the heating plate 1 is disposed within the installation cavity. Of course, the cooking device also has other structural components common to existing cooking devices, which will not be detailed here.
[0127] The following describes the positioning process of the inner pot 2 by the positioning structure in the cooking device of this embodiment with reference to the accompanying drawings:
[0128] like Figure 1 As shown, when the inner pot 2 is not installed in the heating plate 1, the pressure rod assembly is in the first position as a whole, and the positioning assembly is in the retracted position as a whole.
[0129] like Figure 4 As shown, when a certain type of inner pot 2 is installed in the heating plate 1, the inner pot 2 applies downward pressure to the force-bearing end 401, and the push rod 7 moves from its first position to its second position, thereby driving the adjustment member 5 and the transmission rod 8 to move. The first surface 601 of the force-transmitting end 402 slides relative to the second surface 602 of the driving end 301, and the first surface 601 applies a force to the second surface 602 to move toward the extended position, and the positioning rod 11 moves from the retracted position to the extended position until the positioning end 302 abuts the outer wall of the inner pot 2. The distance between the outer wall of the inner pot 2 of this type and the inner wall of the heating plate 1 is relatively close, the moving distance of the positioning end 302 from the retracted position to the extended position is relatively short, and the moving distance of the force-transmitting end 402 from its first position to its second position is relatively short. Part of the distance that the push rod 7 moves from its first position to its second position is consumed and buffered by the adjustment member 5, and the adjustment member 5 is compressed. The length of the adjustment member 5 after compression is L4.
[0130] like Figure 5 As shown, when another type of inner pot 2 is installed in the heating plate 1, the inner pot 2 applies downward pressure to the force-bearing end 401, and the push rod 7 moves from its first position to its second position, thereby driving the adjustment member 5 and the transmission rod 8 to move. The first surface 601 of the force-transmitting end 402 slides relative to the second surface 602 of the driving end 301. The first surface 601 applies a force to the second surface 602 to move toward the extended position, and the positioning rod 11 moves from the retracted position to the extended position until the positioning end 302 abuts the outer wall of the inner pot 2. The distance between the outer wall of the inner pot 2 of this type and the inner wall of the heating plate 1 is longer, the positioning end 302 moves a longer distance from the retracted position to the extended position, and the force-transmitting end 402 moves a longer distance from its first position to its second position. The distance that the push rod 7 moves from its first position to its second position is partially consumed and buffered by the adjustment member 5, and the adjustment member 5 is compressed. The length of the adjustment member 5 after compression is L5, and L4 is less than L5.
[0131] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations are all within the scope defined by the appended claims.
