Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of scrapers for the wok body of a cooking machine, and in particular to a detachable anti-stick scraper device for the wok body of a cooking machine. Background Technology
[0002] The anti-stick scraper on the wok is an important accessory for any cooking machine. During cooking, food easily adheres to the wok's surface. The scraper, as the machine rotates, makes close contact with the wok, scraping away the food from the walls and bottom, ensuring it makes full contact with the heat source and heats evenly, preventing some parts from burning while others remain uncooked. It also removes food residue, reducing carbonization and buildup on the wok, making it easier to clean after each use and extending its lifespan. Finally, it ensures food is thoroughly cooked, preserving the texture and flavor of the dishes.
[0003] Currently, existing anti-stick scrapers for cooking machine pans have the following technical problems: 1. Incomplete scraping: Some anti-stick scrapers are designed to not fully conform to the complex shape of the pan, especially pans with special curvatures or irregular areas. This causes food to easily remain on the edges or in recesses of the pan during cooking, failing to be scraped off in time, resulting in sticking. 2. Coating wear affects anti-stick effect: Many cooking machine pans use non-stick coatings to achieve the anti-stick function. However, the anti-stick scraper is prone to wear and tear on the non-stick coating during long-term friction with the pan. Once the coating is damaged, the anti-stick performance of the pan will be greatly reduced, and even if the anti-stick scraper works normally, it is difficult to prevent food from sticking to the pan. 3. Inconvenient installation and use: The installation structure of some anti-stick scrapers is complex, requiring users to spend a lot of time and effort to install, and may even require the use of special tools during installation. For ordinary users, this is not only difficult to operate, but may also cause the scraper to malfunction or damage the cooking machine due to improper installation. Utility Model Content
[0004] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a detachable anti-stick scraper device for the wok body of a cooking machine, which solves the problems of incomplete scraping, coating wear affecting the anti-stick effect, and inconvenience in installation and use of the existing anti-stick scraper for the wok body of the cooking machine.
[0005] To achieve the above objectives, this utility model provides a detachable anti-stick scraper device for the wok body of a cooking machine, comprising:
[0006] A cookware set, comprising a pot body and a cover, wherein the pot body is mounted on the cover;
[0007] A stirring assembly is provided within the accommodating space formed by the cover and the pot body, and a scraper assembly is provided inside the pot body.
[0008] The stirring assembly includes: a drive motor, a rotating shaft, and a stirring frame; the drive motor is fixedly installed on the outside of the cover; one end of the rotating shaft is connected to the drive end of the drive motor, and the other end passes through a through hole opened on the cover and is connected to the stirring frame disposed on the inner wall of the pot.
[0009] The scraper assembly includes: a scraper mounting base, a limiting structure, an elastic adjustment structure, and a scraper; the scraper mounting base is fixedly mounted on the cover, and a through groove is formed on the scraper mounting base; the limiting structure includes at least one limiting hole formed on the opposite wall of the through groove for lateral positioning of the scraper; the elastic adjustment structure includes at least one compression spring arranged circumferentially along the inner wall of the through groove, the compression spring including a fixed end fixed to the inner wall of the through groove and a free end abutting against the scraper wall; the scraper includes a first plate and a second plate. The first plate has a second plate extending into the pot body; the first plate has a protrusion that mates with the limiting hole, the protrusion is inserted into the limiting hole, and the plate wall surface of the first plate abuts against the free ends of multiple compression springs; the compression springs generate a preload force along the direction in which the protrusion is inserted into the limiting hole; wherein, the pot body vibrates, causing the protrusion to disengage from the limiting hole, and the compression springs drive the scraper to generate lateral displacement in the square through groove through elastic preload force, thereby ensuring that the working surface of the second plate is always in contact with the inner wall of the pot body.
[0010] As a preferred approach, the scraper has a split structure, with the working surface of the second plate being an arc-shaped curved surface adapted to and conforming to the pot body. The arc-shaped curved surface design of the second plate allows for a tight, all-around fit with the inner wall of the pot (especially common wok pot shapes such as round-bottomed and arc-bottomed ones), effectively eliminating gaps caused by shape mismatches in flat scrapers. This allows for more thorough scraping of food residue, oil film, or burnt material from the pot wall, significantly reducing sticking and burning, improving the fit between the scraper and the inner wall of the pot, and enhancing the anti-stick effect. Furthermore, dividing the scraper into a first plate (connecting and positioning part) and a second plate (functional contact part) allows for the individual disassembly, cleaning, or replacement of the easily damaged or frequently used component (the second plate). This effectively avoids material waste from replacing the entire scraper, reducing maintenance and product usage costs. Furthermore, the curved second plate forms a more uniform contact pressure distribution with the inner wall of the pot, avoiding local stress concentration; under the rotation, vibration or impact of food, the curved structure helps to maintain the overall force balance of the scraper, reducing the risk of warping, loosening or displacement; the split structure also allows the first and second plates to be made of different materials or optimized by different processes, thereby improving the overall structural strength and service life.
[0011] As a preferred embodiment, the second plate has an assembly hole at its bottom, which fits onto the rotating shaft, clamping and fixing the second plate between the stirring frame and the rotating shaft. Since the stirring frame is typically a rigid structure, it provides reliable connection rigidity with the rotating shaft. The second plate, clamped and fixed between the stirring frame and the rotating shaft through the assembly hole, is subjected to clamping forces from two directions, ensuring a secure overall fixation. Under complex operating conditions such as pot rotation, food stirring, and vibration, the second plate is not prone to loosening, falling off, or shifting, ensuring the stability and reliability of the scraper's operation. This clamping structure is designed with a certain gap, allowing for easy removal from the clamped state by slight prying, rotation, or axial movement when cleaning or replacing the second plate. This facilitates regular cleaning, inspection, or replacement of the scraper by users or maintenance personnel.
[0012] As a more preferred embodiment, the limiting structure further includes at least one positioning hole formed on the opposite wall of the through groove. The fixed end of the compression spring is inserted into the positioning hole to provide lateral positioning for the compression spring. The second plate typically relies on the elastic force of the compression spring to adhere tightly to the inner wall of the pot and maintain a certain working posture. If the spring shifts laterally, the force direction of the scraper will deviate from the expected direction, thus affecting the scraping effect, fit, and even causing problems such as jamming and abnormal noise. By positioning the compression spring securely, the consistency and accuracy of the direction of the elastic force on the scraper are ensured, thereby improving the smoothness of the scraper's movement and its operational reliability. In addition, if the compression spring is in an unstable state for a long time during movement (such as shaking, friction, misalignment), it is prone to metal fatigue, local wear, breakage, or failure. By rigidly constraining the fixed end of the compression spring through the designed positioning hole, abnormal friction and dynamic load between the compression spring and the surrounding structure are reduced, the risk of abnormal wear of the compression spring is reduced, and its service life is extended.
[0013] As a preferred embodiment, the stirring rack includes multiple stirring blades distributed circumferentially. This circumferential distribution ensures that each blade is responsible for a different angle of food stirring area when the stirring rack rotates. Compared to a single blade or a few blades, multiple blades can cover a wider area inside the pot, ensuring that food is effectively stirred in all areas of the pot (such as the center, edges, and near the walls). This helps achieve "no dead angles" stirring, avoiding localized food accumulation or uneven heating. Furthermore, the even distribution of multiple blades circumferentially makes the force on the stirring rack more balanced during rotation, avoiding vibration, wobbling, or mechanical fatigue caused by excessive force on a single blade. The evenly distributed structural design helps reduce overall center of gravity shift and power imbalance, improving the operational stability and mechanical reliability of the stirring system. It also provides a more balanced load on the drive motor and shaft, which helps extend the service life of core components.
[0014] As a preferred method, at least one of the stirring blades is serrated. The serrated edges increase the contact area and friction between the blade and the food, making it easier for the blade to "hook," "lift," or "throw" the food during rotation, enhancing the fluidity and tossing effect of the food during stir-frying. This is particularly suitable for Chinese cooking that requires rapid stir-frying and tossing, helping to achieve a dynamic effect closer to manual stir-frying. The serrated structure also generates a certain "turbulence" effect, promoting more complex movement trajectories of the food within the pan, further improving the uniformity of stir-frying. Furthermore, during stir-frying, food easily adheres to the pan wall due to high temperatures or forms localized burnt areas; the serrated blades, during the stirring process, can more effectively scrape, turn, or peel food close to the pan wall, reducing the time food stays on the pan wall and the chance of adhesion; preventing further accumulation of burnt material, thus playing a certain role in preventing sticking and controlling food burning.
[0015] As a preferred method, the scraper mounting base is fixedly connected to the cover via a connector. The scraper mounting base is secured to the cover via reliable connectors (such as screws and bolts), ensuring the scraper remains accurately positioned and is less prone to loosening or shifting during operation (especially under complex conditions such as pot rotation, vibration, and food impact). Compared to non-fixed or weak connection methods (such as relying solely on friction or elastic clips), the connector provides stronger structural constraint and vibration resistance, helping to maintain a stable fit between the scraper and the inner wall of the pot, ensuring the continuous effectiveness of anti-sticking and scraping functions. Furthermore, the forces acting on the scraper during operation (such as the reaction force from the inner wall of the pot, the pushing force of the food, and the preload of the spring) need to be transmitted to the fixed structure of the equipment through the mounting base. By directly fixing the mounting base to the stable base of the cover via the connector, direct and effective force transmission can be achieved, avoiding structural deformation, stress concentration, or functional failure caused by unstable connections. This is beneficial for the coordinated force distribution and stable operation of the entire scraper assembly and the internal system of the cooking machine.
[0016] As a preferred method, the type of connector includes bolted connectors. During the operation of the cooking machine, the scraper assembly and its mounting base are subjected to dynamic loads and vibrations due to motor operation, shaft rotation, food stirring, and slight vibrations of the pot. Bolted connectors generate strong axial clamping force through thread preload, forming a stable connection between the scraper mounting base and the cover, effectively resisting these vibrations and impacts and preventing loosening, displacement, or detachment. Furthermore, bolted connections ensure accurate positioning, consistent angles, and uniform force between the scraper mounting base and the cover during assembly, avoiding problems such as scraper misalignment and poor fit caused by improper installation. This helps ensure the optimal working position and contact state between the scraper and the inner wall of the pot, thereby improving the anti-sticking and scraping effects.
[0017] As a preferred method, the scraper is fixedly installed within the receiving space of the pot body. The pot body rotates relative to the scraper around its rotation axis. The scraper removes deposits from the inner wall of the pot through contact friction between the working surface of the second plate and the inner wall. Because the scraper remains fixed, its contact position, angle, and pressure distribution with the inner wall are more stable, preventing displacement or detachment due to rotation or vibration. When the pot body rotates, the working surface of the second plate always remains against a certain area of the inner wall or slides along the wall. Through continuous contact friction, food residue, oil film, or burnt layers can be scraped off more effectively. Compared to the potential detachment of a rotating scraper, the scraping action of a fixed scraper is more continuous and reliable. Furthermore, traditional rotary scrapers generate friction between the pot walls and the scraper body when rotating at high speed with the pot, and additional mechanical wear occurs due to centrifugal force and food impact. The design of this scraper assembly keeps the scraper fixed during use, bearing only the reaction force and friction from the pot wall. This more singular and controllable force state helps reduce wear and fatigue of the scraper (especially the second plate), thus extending its service life. Moreover, the position, angle, and contact pressure of the fixed scraper can be precisely adjusted using mechanical fixing structures (such as bolts, positioning seats, and elastic pads) to adapt to different pot types, food types, or cooking modes. Users or producers can adjust the gap or pressure between the scraper and the inner wall of the pot as needed to achieve optimal scraping effect and anti-stick performance. Compared to rotary scrapers, which are difficult to precisely control the contact state, the fixed scraper design facilitates control and adjustment according to actual needs.
[0018] As a preferred method, the working surface of the second plate is coated with a Teflon coating. The Teflon coating has extremely low surface energy, making it difficult for most foods (such as proteins, starches, and oils) to adhere to its surface. During cooking, the working surface of the second plate is in close contact with the inner wall of the pot. The Teflon coating effectively reduces the adhesion of food, oil films, sauces, etc., to the contact area between the scraper and the pot wall, preventing the formation of stubborn adhesive layers. This helps achieve a more thorough scraping effect while reducing food residue on the scraper and the risk of burning, thus improving cooking quality. Furthermore, applying a Teflon coating to the working surface of the second plate improves scraping efficiency and smoothness, reduces scraper resistance, and because food is less likely to adhere to the Teflon coating surface, food or burnt layers are more easily pushed or peeled off when the scraper scrapes the inner wall of the pot, rather than sticking to the scraper surface. This helps improve scraping efficiency, reduces resistance and energy consumption during scraper movement, makes scraper movement smoother, and reduces the additional load on the motor or transmission system. It also helps improve the smoothness and reliability of the overall stir-frying and scraping process.
[0019] As described above, the detachable anti-stick scraper device for a wok body of this utility model has the following beneficial effects: When in use, the second plate, as the working part that directly contacts the inner wall of the wok, always adheres tightly to the wok wall under the action of the elastic adjustment structure; even if the wok body vibrates or shifts due to motor operation, food turning, or heating expansion, causing the conventional fixed scraper to lose contact, this utility model uses the elastic preload of the compression spring to push the scraper to move laterally, ensuring that the working surface of the second plate remains in contact with the inner wall of the wok; thereby effectively scraping away food residue, grease, and burnt layers, preventing food from sticking and burning, ensuring uniform heating during the cooking process and optimizing the appearance and taste of the finished product, achieving continuous anti-sticking and automatic scraping of the inner wall of the wok, and improving cooking quality.
[0020] The scraper mounting base is fixed to the cover, and the entire scraper assembly can be quickly installed and removed through the mounting base; the second plate, as a vulnerable or frequently cleaned component, can be removed separately for cleaning, replacement or maintenance, without the need to replace the entire scraper assembly or disassemble the pot body; this design helps to reduce maintenance difficulty and usage costs, and improve the ease of use of the product.
[0021] The scraper assembly is integrated into the space between the pot body and the cover, without taking up additional cooking space inside the pot body; the scraper mounting base, elastic structure and limiting structure are reasonably laid out, working together with the stirring assembly to form a complete stir-frying and anti-sticking system; the overall structure is compact, which is conducive to the arrangement and optimization of other functional components inside the cooking machine.
[0022] The elastic adjustment structure uses multiple compression springs arranged circumferentially along the inner wall of the channel to make the scraper more evenly stressed, avoid local stress concentration, and enable the scraper to maintain a stable posture during operation. This reduces skewing, jamming, or abnormal wear caused by uneven stress. This structural design helps to extend the service life of the scraper (especially the second plate) and reduce the failure rate and maintenance frequency during long-term use.

It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit the utility model.
[0054] like Figures 1 to 5 As shown, this utility model provides a detachable anti-stick scraper device for the wok body of a cooking machine, comprising:
[0055] The cookware 1 includes a pot body 11 and a cover 12, with the pot body 11 mounted on the cover 12;
[0056] A stirring assembly 2 is provided in the accommodating space formed by the cover 12 and the pot body 11, and a scraper assembly 3 is provided in the pot body 11.
[0057] The stirring assembly 2 includes: a drive motor 21, a rotating shaft 22, and a stirring frame 23; the drive motor 21 is fixedly installed on the outside of the cover 12; one end of the rotating shaft 22 is connected to the driving end of the drive motor 21, and the other end passes through a through hole opened on the cover 12 and is connected to the stirring frame 23 set on the inner wall of the pot body 11.
[0058] The scraper assembly 3 includes: a scraper mounting base 31, a limiting structure, an elastic adjustment structure, and a scraper 33; the scraper mounting base 31 is fixedly mounted on the cover 12, and a through groove 311 is provided on the scraper mounting base 31; the limiting structure includes at least one limiting hole 312 opened on the opposite wall of the through groove 311 for laterally positioning the scraper 33; the elastic adjustment structure includes at least one compression spring 32 arranged circumferentially along the inner wall of the through groove 311, the compression spring 32 including a fixed end fixed to the inner wall of the through groove 311 and a free end abutting against the wall surface of the scraper 33; the scraper 33 includes a first plate 332 and a second plate 333, the second... Plate 333 extends into pot body 11; a protrusion 331 that mates with the limiting hole 312 is provided on the first plate 332, the protrusion 331 is inserted into the limiting hole 312, and the plate wall surface of the first plate 332 abuts against the free ends of multiple compression springs 32; the direction of the preload generated by the compression springs 32 is along the direction in which the protrusion 331 is inserted into the limiting hole 312; wherein, the vibration of pot body 11 causes the protrusion 331 to disengage from the limiting hole 312, and the compression springs 32 drive the scraper 33 to generate lateral displacement in the through groove 311 through the elastic preload, thereby making the working surface of the second plate 333 always adhere to the inner wall of the pot body 11. When the cooking machine is in use, the drive motor 21 is started. The drive motor 21 drives the rotating shaft 22 connected to its output end to rotate. The rotation of the rotating shaft 22 drives the stirring rack 23 connected to it to rotate. The rotation of the stirring rack 23 drives the pot body 11 to rotate relative to the scraper 33 around its rotation axis 22. Through the contact friction between the working surface of the second plate 333 and the inner wall of the pot body 11, the adhering substances on the inner wall of the pot body 11 are removed.
[0059] In some embodiments of this utility model, such as Figures 3 to 5As shown, the scraper 33 has a split structure, and the working surface of the second plate 333 is an arc-shaped curved surface that fits and conforms to the pot body 11. The arc-shaped curved surface design of the second plate 333 allows it to fit tightly and comprehensively with the inner wall of the pot body 11 (especially common wok pot types such as round bottom and arc bottom), effectively eliminating gaps caused by shape mismatch of the flat scraper 33; it can more thoroughly scrape away food residue, oil film, or burnt matter on the pot wall, significantly reducing the occurrence of sticking and burning, improving the fit between the scraper 33 and the inner wall of the pot body 11, and enhancing the anti-stick effect. In addition, dividing the scraper 33 into a first plate 332 (connection and positioning part) and a second plate 333 (functional contact part) allows easily damaged or frequently used parts (second plate 333) to be disassembled, cleaned, or replaced separately; it can effectively avoid material waste caused by replacing the whole part and reduce maintenance and product usage costs. Furthermore, the curved surface of the second plate 333 creates a more uniform contact pressure distribution between itself and the inner wall of the pot body 11, avoiding localized stress concentration. Under the rotation, vibration, or impact of food in the pot body 11, the curved structure helps maintain the overall force balance of the scraper 33, reducing the risk of warping, loosening, or displacement. The split structure also allows the first plate 332 and the second plate 333 to be optimized with different materials or processes, thereby improving the overall structural strength and service life.
[0060] In some embodiments of this utility model, such as Figure 1 and Figure 5 As shown, the bottom of the second plate 333 has an assembly hole 3331, which is fitted onto the rotating shaft 22, so that the second plate 333 is clamped and fixed between the stirring frame 23 and the rotating shaft 22. Since the stirring frame 23 is usually a rigid structure, it has reliable connection rigidity with the rotating shaft 22; the second plate 333 is clamped and fixed between the stirring frame 23 and the rotating shaft 22 through the assembly hole 3331, and is subjected to clamping forces from two directions, so the whole is firmly fixed; under complex working conditions such as the rotation of the pot body 11, stirring of food, and vibration, the second plate 333 is not easy to loosen, fall off or shift, ensuring the stability and reliability of the scraper 33. The clamping structure is designed with a certain gap, so when it is necessary to clean or replace the second plate 333, it can be removed from the clamped state by slight prying, rotation or axial movement, and the overall disassembly process is relatively simple; it is beneficial for users or maintenance personnel to clean, inspect or replace the scraper 33 regularly.
[0061] In some embodiments of this utility model, such as Figures 3 to 6As shown, the limiting structure also includes at least one positioning hole 313 opened on the opposite wall of the through groove 311. The fixed end of the compression spring 32 is inserted into the positioning hole 313 to position the compression spring 32 laterally. The second plate 333 usually relies on the elastic force of the compression spring 32 to stick tightly to the inner wall of the pot body 11 and maintain a certain working posture. If the compression spring 32 shifts laterally, the force direction of the scraper 33 will deviate from the expected direction, which will affect the scraping effect, the fit, and even cause problems such as jamming and abnormal noise. By positioning the scraper 33 with a stable compression spring 32, the consistency and accuracy of the direction of the elastic force on the scraper 33 are ensured, thereby improving the smoothness of the scraper 33's movement and the reliability of its operation. Furthermore, if the compression spring 32 is in an unstable state for a long time during movement (such as shaking, friction, misalignment), it is prone to metal fatigue, local wear, breakage or failure. The fixed end of the compression spring 32 is rigidly constrained by the designed positioning hole 313, which reduces abnormal friction and dynamic load between the compression spring 32 and the surrounding structure, reduces the risk of abnormal wear of the compression spring 32, and extends its service life.
[0062] In some embodiments of this utility model, such as Figure 1 As shown, the stirring rack 23 includes multiple stirring blades distributed along the circumference. This circumferential distribution ensures that each blade is responsible for stirring different areas of the food when the stirring rack 23 rotates. Compared to a single blade or a few blades, multiple blades can cover a wider area of the pot, ensuring that food in all areas of the pot 11 (such as the center, edges, and near the walls) is effectively stirred. This helps achieve "no dead angles" in stirring, avoiding localized food accumulation or uneven heating. Furthermore, the even distribution of multiple blades along the circumference makes the force on the stirring rack 23 more balanced during rotation, avoiding vibration, swaying, or mechanical fatigue caused by excessive force on a single blade. The evenly distributed structural design helps reduce overall center of gravity shift and power imbalance, improving the operational stability and mechanical reliability of the stirring system. It also provides a more balanced load on the drive motor 21 and the rotating shaft 22, which helps extend the service life of core components.
[0063] In some embodiments of this utility model, such as Figure 1As shown, at least one of the stirring blades is serrated (B). The serrated edge of the blade increases the contact area and friction between the blade and the food, making it easier for the blade to "hook," "lift," or "throw" the food during rotation, enhancing the fluidity and tossing effect of the food during stir-frying. It is particularly suitable for Chinese cooking that requires rapid stir-frying and tossing, helping to achieve a dynamic effect closer to manual stir-frying. The serrated structure also generates a certain "turbulence" effect, promoting the food to form a more complex movement trajectory within the pot 11, further improving the uniformity of stir-frying. In addition, during the stir-frying process, food is prone to sticking to the pot wall or forming localized scorching due to high temperatures. During the stirring process, the serrated blade can more effectively scrape, turn, or peel the food close to the pot wall, reducing the time the food stays on the pot wall and the chance of adhesion; preventing further accumulation of scorched material, and playing a certain role in preventing sticking and controlling the scorching of food.
[0064] In some embodiments of this utility model, such as Figure 1 As shown, the scraper mounting base 31 is fixedly connected to the cover 12 via a connector 34. The scraper mounting base 31 is securely fixed to the cover 12 via a reliable connector 34 (such as screws or bolts), ensuring that the scraper 33 maintains accurate positioning and is not easily loosened or shifted during operation (especially under complex conditions such as rotation of the pot body 11, vibration, and impact of food). Compared to non-fixed or weak connection methods (such as relying solely on friction or elastic clips), the connector 34 provides stronger structural constraint and vibration resistance, helping to maintain a stable fit between the scraper 33 and the inner wall of the pot body 11, ensuring the continuous effectiveness of the anti-sticking and scraping functions. Furthermore, the forces acting on the scraper 33 during operation (such as the reaction force from the inner wall of the pot 11, the pushing force of the food, the preload of the spring, etc.) need to be transmitted to the fixed structure of the equipment through the scraper mounting seat 31. By directly fixing the scraper mounting seat 31 to the stable base of the cover 12 through the connector 34, the force can be directly and effectively transmitted, avoiding structural deformation, stress concentration or functional failure caused by unstable connection. This is beneficial to the coordinated force and stable operation of the entire scraper 33 assembly and the internal system of the cooking machine.
[0065] In some embodiments of this utility model, such as Figure 1 and Figure 3As shown, the type of connector 34 includes bolt connector 34. During the operation of the cooking machine, due to the operation of the motor, the rotation of the shaft 22, the turning of the ingredients, and the slight vibration of the pot body 11, the scraper assembly 3 and its scraper mounting seat 31 will be subject to certain dynamic loads and vibrations. The bolt connector 34 generates a strong axial clamping force through the thread preload, so that the scraper mounting seat 31 and the cover 12 form a stable connection, which can effectively resist these vibrations and impacts and prevent the connection from loosening, displacement or falling off. In addition, the bolt connection can ensure that the scraper mounting seat 31 and the cover 12 are accurately positioned, have consistent angles and uniform force during the assembly process, avoiding problems such as scraper 33 offset and poor fit caused by improper installation; it is beneficial to ensure the optimal working position and contact state between the scraper 33 and the inner wall of the pot body 11, thereby improving the anti-sticking and scraping effect.
[0066] In some embodiments of this utility model, such as Figures 3 to 6 As shown, the scraper 33 is fixedly installed within the accommodating space of the pot body 11. The pot body 11 rotates relative to the scraper 33 around its rotation axis 22. Through the contact friction between the working surface of the second plate 333 and the inner wall of the pot body 11, the adhering substances on the inner wall of the pot body 11 are removed. Because the scraper 33 remains fixed, its contact position, angle, and pressure distribution with the inner wall of the pot body 11 are more stable and will not shift or detach due to the rotation or vibration of the scraper 33 itself. When the pot body 11 rotates, the working surface of the second plate 333 always adheres to a certain area of the inner wall of the pot body 11 or slides along the wall surface. Through continuous contact friction, it can more effectively scrape off food residue, oil film, or burnt layer. Compared with the possible detachment of the rotating scraper 33, the scraping action of the fixed scraper 33 is more continuous and reliable. Furthermore, when a traditional rotating scraper 33 rotates at high speed with the pot body 11, friction occurs between the pot walls, and additional mechanical wear is caused by centrifugal force and food impact. The design of this scraper assembly 3 keeps the scraper 33 fixed during use, bearing only the reaction force and friction from the pot wall. The force state is more singular and controllable, which helps reduce the wear and fatigue of the scraper 33 (especially the second plate 333), thus helping to extend the service life of the scraper 33. Furthermore, the position, angle, and contact pressure of the fixed scraper 33 can be precisely adjusted through mechanical fixing structures (such as bolts, positioning seats, elastic pads, etc.) to adapt to different pot types, food types, or cooking modes. Users or producers can adjust the gap or pressure between the scraper 33 and the inner wall of the pot body 11 according to their needs to obtain the best scraping effect and anti-stick performance. Compared with the rotating scraper 33, which is difficult to precisely control the contact state, the design of the fixed scraper 33 helps to control and adjust according to actual needs.
[0067] In some embodiments of this utility model, such as Figure 6As shown, the working surface of the second plate 333 is covered with a Teflon coating. The Teflon coating has extremely low surface energy, making it difficult for most food ingredients (such as proteins, starches, and oils) to adhere to or stick to its surface. During cooking, the working surface of the second plate 333 is in close contact with the inner wall of the pot body 11. The Teflon coating can effectively reduce the adhesion of food ingredients, oil films, sauces, etc. in the contact area between the scraper 33 and the pot wall, avoiding the formation of a stubborn adhesion layer. This helps to achieve a more thorough scraping effect, while reducing the residue of food on the scraper 33 and the risk of burning, thus improving the cooking quality. Furthermore, applying a Teflon coating to the working surface of the second plate 333 can improve scraping efficiency and smoothness, reduce the resistance of the scraper 33, and because food does not easily adhere to the Teflon coating surface, when the scraper 33 scrapes the inner wall of the pot 11, the food or charred layer is more easily pushed or peeled off, rather than sticking to the surface of the scraper 33; this helps to improve scraping efficiency, reduce resistance and energy consumption during the movement of the scraper 33, make the movement of the scraper 33 smoother, and reduce the additional load on the motor or transmission system; it also helps to improve the smoothness and reliability of the overall stir-frying and scraping process.
[0068] As described above, the detachable anti-stick scraper device for the wok body of this utility model has the following beneficial effects: When the detachable anti-stick scraper device for the wok body of this utility model is used, the second plate 333, as a working part that directly contacts the inner wall of the wok body 11, always adheres tightly to the wok wall under the action of the elastic adjustment structure; even if the wok body 11 vibrates or shifts due to motor operation, food turning, or heating expansion, causing the conventional fixed scraper 33 to lose contact, this utility model uses the elastic pre-tension force of the compression spring 32 to push the scraper 33 to move laterally, ensuring that the working surface of the second plate 333 remains in contact with the inner wall of the wok body 11; thereby effectively scraping off food residue, grease, and burnt layers, preventing food from sticking and burning, ensuring uniform heating during the cooking process and optimizing the appearance and taste of the finished product, achieving continuous anti-sticking and automatic scraping of the inner wall of the wok body 11, and improving cooking quality.
[0069] The scraper 33 mounting base is fixed on the cover 12, and the scraper assembly 3 can be quickly installed and removed through the mounting base; the second plate 333, as a vulnerable or frequently cleaned component, can be removed separately for cleaning, replacement or maintenance, without the need to replace the entire scraper assembly 3 or disassemble the pot body 11; this design helps to reduce maintenance difficulty and usage costs, and improve the ease of use of the product.
[0070] The scraper assembly 3 is integrated into the space between the pot body 11 and the cover 12, without occupying additional cooking space inside the pot body 11; the scraper mounting seat 31, elastic structure and limiting structure are reasonably arranged, and work together with the stirring assembly 2 to form a complete stir-frying and anti-sticking system; the overall structure is compact, which is conducive to the arrangement and optimization of other functional components inside the cooking machine.
[0071] The elastic adjustment structure uses multiple compression springs 32 arranged circumferentially along the inner wall of the through groove 311 to make the scraper 33 more evenly stressed, avoid local stress concentration, and enable the scraper 33 to maintain a stable posture during operation. This reduces the deviation, jamming or abnormal wear caused by uneven force. This structural design helps to extend the service life of the scraper 33 (especially the second plate 333) and reduce the failure rate and maintenance frequency during long-term use.
[0072] In summary, the detachable anti-stick scraper device for the wok body of this utility model has the following advantages:
[0073] 1. Excellent non-stick scraping effect, improving cooking quality.
[0074] Under the action of the elastic adjustment structure, the second plate 333 always sticks tightly to the inner wall of the pot body 11. When the pot body 11 vibrates or shifts, the compression spring 32 pushes the scraper 33 to automatically reset and stick together, ensuring continuous scraping of food residue, grease and burnt layer, preventing sticking and burning, achieving uniform heating of food, and optimizing the appearance and taste of the finished product.
[0075] 2. Easy to install and maintain, reducing operating costs.
[0076] The scraper 33 mounting base is fixed to the cover 12, and the scraper assembly 3 can be quickly installed and removed as a whole; the second plate 333 can be removed separately for cleaning, replacement or maintenance, without disassembling the pot body 11 or replacing the entire assembly, which significantly reduces maintenance difficulty and user cost, and improves product convenience.
[0077] 3. Compact structure and high space utilization
[0078] The scraper assembly 3 is designed within the space between the pot body 11 and the cover 12, without occupying the cooking space inside the pot; the layout of each component is reasonable, and it works in conjunction with the stirring assembly 2, optimizing the internal structure of the cooking machine and leaving design margin for other functional modules.
[0079] 4. Balanced stress distribution extends service life.
[0080] The elastic adjustment structure uses multiple compression springs 32 arranged circumferentially to ensure that the scraper 33 is subjected to uniform force, avoid local stress concentration, reduce skewing, jamming and abnormal wear, improve the working stability of the scraper 33, extend the service life of key components such as the second plate 333, and reduce the failure rate and maintenance frequency.
[0081] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.
