Description

Technical Field

[0001] This application relates to the field of kitchenware technology, and in particular to a stirring structure, a stir-frying device, and an intelligent stir-frying machine. Background Technology

[0002] Stir-frying is the most basic and widely used cooking technique. In traditional cooking, stirring is crucial for heating ingredients. With stirring as the basic action, the ingredients move continuously in the pan, receiving heat from multiple angles while preventing burning. To facilitate stirring, save labor, and avoid the uncertainties of manual operation, an automatic stir-fry machine has been designed. An automatic stir-fry machine generally includes a stirring mechanism and a container for holding food. The container heats the food inside, and the stirring mechanism automatically stirs the food in the container under electric power.

[0003] In related technologies, food tends to stick to the inner wall of the container during cooking in automatic cooking machines, which can lead to a series of problems. First, the sticky food affects the evenness of cooking, causing uneven heating and thus affecting the cooking quality. Therefore, a scraper is usually installed on the stirring mechanism, which slides along the pot wall to simulate the action of scraping the pot.

[0004] However, although the pot body is a rotating body, due to the limitations in the production of the pot body and the possible deformation of the pot body in the future, it is impossible to guarantee that the distance between the pot wall at the same height and the center line of the pot body is consistent. Therefore, when the scraper rotates, the scraper may not contact part of the inner wall of the pot body, which will affect the scraping effect. The scraper may also have excessive contact with part of the inner wall of the pot body, which will damage the scraper and the pot body. Utility Model Content

[0005] This application provides a stirring structure, a cooking device, and an intelligent cooking machine to solve the technical problems in related technologies where, because the pot body is not strictly a rotating body, when the scraper rotates to scrape the pot, some parts of the pot wall are not scraped, affecting the scraping effect, and there is also the technical problem that the scraper and the pot body are damaged due to excessive contact.

[0006] In a first aspect, a stirring structure is provided, comprising:

[0007] A driving mechanism, comprising a driving component and a connecting shaft, wherein the driving component is drivingly connected to the connecting shaft to drive the connecting shaft to rotate.

[0008] Multiple spatula mechanisms are provided, each including a connecting member, an elastic connecting assembly, and a scraper. One end of the connecting member is connected to a connecting shaft to rotate with it. The scraper is elastically connected to the connecting member via the elastic connecting assembly, and the elastic movement direction of the scraper is radially aligned with the connecting shaft. One side of the scraper conforms to the shape of the pot wall. Multiple scrapers are spaced apart vertically.

[0009] The rotation axis of the connecting shaft is collinear with the center line of the pot body. One side of the scraper is used to fit against the pot wall. As the connecting shaft rotates, the scraper slides on the inner wall of the pot body, and the elastic force of the elastic connecting component keeps the scraper pressed against the inner wall of the pot body.

[0010] In some embodiments, the resilient connection component includes:

[0011] A guide sleeve is fixed to the connecting member, and the length direction of the guide sleeve is consistent with the radial direction of the connecting shaft;

[0012] A guide rod passes through the guide sleeve and is fixed to the scraper.

[0013] A limiting structure that restricts the rotation of the guide rod relative to the guide sleeve;

[0014] An elastic element, the two ends of which are respectively connected to the guide sleeve and the guide rod.

[0015] In some embodiments, the limiting structure includes a limiting notch formed on the circumferential side of the guide rod, so that the guide rod is a non-rotating body, and the circumferential inner side of the guide sleeve fits into the circumferential outer side of the guide rod.

[0016] In some embodiments, the plane of the scraper is set at an acute angle to the radial direction of the connecting shaft, so that one side of the scraper is inclined and pressed against the inner wall of the pot body.

[0017] In some embodiments, the scraper includes:

[0018] The main body plate has one side surface that is attached to the inner wall of the pot.

[0019] A connecting plate is connected to the elastic connecting assembly, and the connecting plate is bolted to the main plate and welded at the connection point.

[0020] In some embodiments, the scraper surface is provided with a polytetrafluoroethylene coating.

[0021] In some embodiments, the connecting member includes:

[0022] A connecting rod, wherein the elastic connecting assembly is connected to the connecting rod;

[0023] A connecting sleeve is fixed to the connecting rod. The connecting sleeve is sleeved on the connecting shaft, and the connecting end of the connecting shaft for the connecting sleeve to be sleeved is non-rotating. The inner circumferential side of the connecting sleeve is in contact with the outer circumferential side of the connecting end of the connecting shaft. Multiple connecting sleeves are stacked.

[0024] In some embodiments, the stirring structure further includes a connecting nut, which is threaded to the top end of the connecting shaft, the bottom end face of the connecting nut abutting against the connecting sleeve, and the tightening direction of the connecting nut is opposite to the rotation direction of the connecting shaft.

[0025] Secondly, a cooking device is provided, including a pot body and a stirring structure as described above.

[0026] Thirdly, a smart cooking machine is provided, including the stirring structure described above, and / or the cooking device described above.

[0027] The beneficial effects of the technical solution provided in this application include:

[0028] This application provides a stirring structure, a cooking device, and an intelligent cooking machine. During cooking, the drive mechanism rotates the connecting shaft, which in turn drives multiple scraper mechanisms to rotate within the pot. At this time, multiple scrapers simultaneously scrape against the pot to lift the food from the pot. Due to the elastic connecting component, the scrapers are kept pressed against the inner wall of the pot by the elasticity. Even if the pot is not strictly a rotating body, the scrapers can still stay close to the pot wall at all times, ensuring that food at any position on the pot wall can be lifted, thus optimizing the scraping effect. In addition, since the scrapers can move radially along the connecting shaft, there is no situation where the scrapers excessively press against the pot wall, which is less likely to cause damage to the pot and the scrapers.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] This application provides a stirring structure, a cooking device, and an intelligent cooking machine. The scraper in the stirring structure is connected to a connecting member via an elastic connecting component and rotates with the connecting shaft. Due to the elasticity, the scraper remains close to the pot wall at all times, ensuring that food from any position on the pot wall can be scraped up, thus optimizing the scraping effect. Furthermore, because the scraper can move radially along the connecting shaft, it avoids excessive pressure on the pot wall, reducing the risk of damage to the pot and scraper. This application addresses the technical problems in related technologies where, because the pot body is not strictly a rotating body, some parts of the pot wall are not scraped up when the scraper rotates to scrape the pot, affecting the scraping effect, and there is also the technical problem of excessive contact between the scraper and the pot body causing damage to both the pot and scraper.

[0038] Reference Figure 1 and Figure 5 A stirring structure includes a driving mechanism and multiple shovel mechanisms 2, which are all driven by the driving mechanism to rotate and perform shovel operations on the inner walls of the pot body 4 at different heights.

[0039] Reference Figure 1 , Figure 2 and Figure 5The driving mechanism includes a driving component (not shown in the figure) and a connecting shaft 1. The driving component is installed outside the pot body 4, and the connecting shaft 1 extends from the bottom of the pot body 4 into the interior of the pot body 4, with the center line of the connecting shaft 1 aligned with the center line of the pot body 4. The driving component drives the connecting shaft 1 to rotate. In this embodiment, the driving component includes a motor. By driving the connecting shaft 1 to rotate, multiple pot-scraping mechanisms 2 are driven to rotate within the pot body 4 to achieve the pot-scraping operation.

[0040] Reference Figures 1-3 The pot-scraping mechanism 2 includes a connecting member 21, an elastic connecting assembly 22, and a scraper 23. One end of the connecting member 21 is connected to the connecting shaft 1 to rotate with it. The scraper 23 is elastically connected to the connecting member 21 via the elastic connecting assembly 22, and the elastic movement direction of the scraper 23 is consistent with the radial direction of the connecting shaft 1. One side of the scraper 23 conforms to the shape of the pot wall of the pot body 4. Multiple scrapers 23 are spaced apart circumferentially on the connecting shaft 1 and spaced apart vertically. Each scraper 23 is attached to the inner wall of the pot body 4 at different heights to achieve pot-scraping operation on the entire inner wall of the pot body 4. In this embodiment, the pot-scraping mechanism 2 includes two sets.

[0041] With this configuration, since the centerline of the connecting shaft 1 is collinear with the centerline of the pot body 4, when the connecting shaft 1 rotates, its rotation axis is also collinear with the centerline of the pot body 4. One side of the scraper 23 is in contact with the inner wall of the pot body 4, and as the connecting shaft 1 rotates, the scraper 23 slides on the inner wall of the pot body 4. In addition, the elastic force of the elastic connecting component 22 keeps the scraper 23 pressed against the inner wall of the pot body 4. Even if the pot body 4 is not a strictly rotating body, the scraper 23 can still be kept pressed against the inner wall of the pot body 4 under the action of the elastic connecting component 22, ensuring the scraper 23 is effective in scraping the pot.

[0042] Reference Figures 1-3 Specifically, the elastic connecting assembly 22 includes a guide sleeve 221, a guide rod 222, a limiting structure 22a, and an elastic element 223. The guide sleeve 221 is welded and fixed to the connecting member 21, and the length direction of the guide sleeve 221 is consistent with the radial direction of the connecting shaft 1. The guide rod 222 passes through the guide sleeve 221 and is welded and fixed to the scraper 23. The sliding engagement of the guide rod 222 and the guide sleeve 221 can limit the sliding direction of the scraper 23, ensuring that the scraper 23 can only move radially along the connecting shaft 1, and preventing the scraper 23 from moving arbitrarily and losing its contact with the inner wall of the pot body 4.

[0043] Reference Figures 1-3The two ends of the elastic element 223 are connected to the guide sleeve 221 and the guide rod 222, respectively. The elastic force of the elastic element 223 constantly pushes the guide rod 222 and the guide sleeve 221 away from each other, so that the scraper 23 remains pressed against the pot wall. In this embodiment, the elastic element 223 includes a spring, which is sleeved on the guide rod 222. The inner wall of the guide sleeve 221 and the outer side of the guide rod 222 both have stepped surfaces for the two ends of the spring to abut against.

[0044] This design allows the guide sleeve 221, guide rod 222, and elastic element 223 to be easily disassembled for cleaning and maintenance, and also facilitates the assembly of the spatula mechanism 2.

[0045] Reference Figures 1-3 The limiting structure 22a restricts the rotation of the guide rod 222 relative to the guide sleeve 221 to ensure the scraper 23 adheres to the inner wall of the pot body 4, thus ensuring the scraping effect. In this embodiment, the limiting structure 22a includes a limiting notch, which is formed on the circumferential side of the guide rod 222, so that the guide rod 222 is a non-rotating body. The circumferential inner side of the guide sleeve 221 fits into the circumferential outer side of the guide rod 222. By designing the shape of the guide rod 222, the relative rotation of the guide rod 222 and the guide sleeve 221 can be restricted to ensure the adherence of the scraper 23 to the inner wall of the pot body 4. Preferably, the cross-section of the guide rod 222 is D-shaped.

[0046] Reference Figure 4 and Figure 5 In this embodiment, the plane of the scraper 23 is set at an acute angle to the radial direction of the connecting shaft 1, so that one side of the scraper 23 is inclined and pressed against the inner wall of the pot body 4. As the scraper 23 slides on the inner wall of the pot body 4, the scraper 23 is inclined and scrapes the pot, which greatly reduces the resistance generated when the cover plate and the pot body 4 move relative to each other, and reduces the wear on the scraper 23.

[0047] Reference Figures 1-3 Specifically, the scraper 23 includes a main plate 231 and a connecting plate 232. One side of the main plate 231 is in contact with the inner wall of the pot body 4. The connecting plate 232 is connected to the elastic connecting assembly 22, and the connecting plate 232 is bolted to the main plate 231 and welded at the connection point.

[0048] This design, by separating the scraper 23, allows for different shapes of the main body plate 231 depending on the shape of the pot body 4, while the connecting plate 232 can still be shared, thus broadening the compatibility of the parts. Furthermore, the connecting plate 232 is fixed to the main body plate 231 by both bolts and welding, ensuring that the main body plate 231 and the connecting plate 232 are firmly fixed.

[0049] In this embodiment, the guide rod 222 and the connecting plate 232 are fixed by welding.

[0050] The scraper 23 has a polytetrafluoroethylene (PTFE) coating. This PTFE coating has a very low coefficient of friction, enhancing the lubrication of the scraper 23 surface and reducing frictional resistance between the scraper 23 and the inner surface of the pot body 4, thereby improving the scraper 23's ability to clean adhered food. The PTFE coating also has good anti-stick properties, preventing food from adhering to the scraper 23 surface and making it easy to clean. The PTFE coating can withstand temperatures up to 260℃ and is not easily peeled off, extending the service life of the scraper 23. PTFE is an inert compound and will not produce a chemical reaction upon direct contact with food, making it safe to use.

[0051] Reference Figures 1-3 The connecting member 21 includes a connecting rod 211 and a connecting sleeve 212. The elastic connecting assembly 22 is connected to the connecting rod 211. Specifically, the guide sleeve 221 of the elastic connecting assembly 22 is welded and fixed to one end of the connecting rod 211.

[0052] Reference Figures 1-3 The connecting sleeve 212 is welded and fixed to the connecting rod 211. The connecting sleeve 212 is sleeved on the connecting shaft 1, and the connecting end of the connecting shaft 1 for which the connecting sleeve 212 is sleeved is non-rotating. In this embodiment, the cross-section of the portion of the connecting shaft 1 for which the connecting sleeve 212 is sleeved is racetrack-shaped. The circumferential inner side of the connecting sleeve 212 is attached to the circumferential outer side of the connecting end of the connecting shaft 1. Multiple connecting sleeves 212 of the spatula mechanism 2 are stacked.

[0053] This configuration restricts the relative movement of the connecting member 21 and the connecting shaft 1 by using the shapes of the connecting sleeve 212 and the connecting shaft 1, ensuring that the spatula mechanism 2 is driven to rotate.

[0054] Reference Figures 1-3 Furthermore, the stirring structure also includes a connecting nut 3, which is threaded to the top of the connecting shaft 1. The bottom surface of the connecting nut 3 is pressed against the connecting sleeve 212, and the tightening direction of the connecting nut 3 is opposite to the rotation direction of the connecting shaft 1.

[0055] This configuration restricts the connecting member 21 from disengaging from the connecting shaft 1 by using the connecting nut 3, and by designing the tightening direction of the connecting nut 3, it ensures that the connecting nut 3 and the connecting shaft 1 will not loosen during the rotation of the connecting shaft 1.

[0056] Secondly, a cooking device is provided, including a pot body 4 and a stirring structure as described above.

[0057] Thirdly, a smart cooking machine is provided, including the stirring structure described above, and / or the cooking device described above.

[0058] The beneficial effects of the technical solution provided in this application include:

[0059] This application provides a stirring structure, a cooking device, and an intelligent cooking machine. During cooking, the drive mechanism drives the connecting shaft 1 to rotate, and the connecting shaft 1 simultaneously drives multiple scraper mechanisms 2 to rotate inside the pot body 4. At this time, multiple scrapers 23 scrape on the pot body 4 simultaneously to scoop up the food on the pot body 4. Due to the setting of the elastic connecting component 22, the elasticity makes the scraper 23 continuously press against the inner wall of the pot body 4. Even if the pot body 4 is not a strictly rotating body, the scraper 23 can still be close to the pot wall at all times, ensuring that food at any position on the pot wall can be scooped up, thus optimizing the scraping effect. In addition, since the scraper 23 can move radially along the connecting shaft 1, the scraper 23 will not press excessively against the pot wall, which is less likely to cause damage to the pot body 4 and the scraper 23.
