[0022] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0023] Unless otherwise defined, all technical and scientific terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in the embodiments of this application is for descriptive purposes only and is not intended to limit the scope of this application.

[0024] like Figure 1 and Figure 2 As shown in the embodiment of this application, a stirring device 1 can be used in a cooking machine to stir a mixture of water and powder (such as cornstarch and water) to maintain the mixture in a better mixing state. Specifically, the stirring device 1 includes a storage tank 11, stirring elements 12, and a drive assembly 13. The storage tank 11 has a cavity 111 for storing the raw materials to be stirred. The stirring elements 12 are located in the cavity 111 and are spaced apart. Each stirring element 12 is movably connected to the bottom wall of the storage tank 11, allowing it to move relative to the storage tank 11. The drive assembly 13 is connected to the bottom of the storage tank 11 and has multiple drive ends corresponding to the number of stirring elements 12. Each drive end is used to drive the corresponding stirring element 12 without contact, thereby stirring the raw materials stored in the cavity 111.

[0025] Specifically, the receiving cavity 111 formed by the storage tank 11 is typically used to hold liquid and solid mixed ingredients, such as water and cornstarch, to form a thickening sauce. In addition, it can also be used to hold other different liquid ingredients to mix them into the desired liquid. The top of the storage tank 11 usually has an opening for the ingredients to be stirred to be placed into the receiving cavity 111. When it is not necessary to put in ingredients or take out the stirred liquid, the opening of the storage tank 11 can be covered by a cover to prevent contamination of the liquid. Optionally, to facilitate observation of the remaining liquid level, the storage tank 11 can be made of a transparent material, or a portion of the storage tank 11 can be made transparent, allowing observation of the liquid inside through the transparent portion.

[0026] The agitator 12 is used to agitate the raw materials in the receiving cavity 111 to fully mix the various raw materials. At least two agitators 12 are spaced apart, and each agitator 12 can be connected to different positions on the bottom wall of the storage tank 11 to agitate the raw materials in different areas of the receiving cavity 111. Optionally, to improve the uniformity of agitation, multiple agitators 12 can be evenly distributed on the bottom wall of the storage tank 11 to ensure consistent agitation uniformity of the liquid material throughout the receiving cavity 11. It is understood that the number, size, and specific installation position of the agitators 12 can be flexibly designed, as long as the usage requirements are met.

[0027] The drive assembly 13 has drive ends for driving the corresponding stirring components 12. Depending on the design, the drive assembly 13 can have one or more drive modes. For example, in one drive mode, all drive ends can be activated simultaneously to drive all stirring components 12 to move simultaneously; in another drive mode, some drive ends can be activated alternately with others. Of course, the drive assembly 13 can also adopt other drive modes. When multiple modes are available, they can be switched according to user needs to achieve the best driving and stirring effect.

[0028] Optionally, the drive assembly 13 can include a drive member and a transmission member, with multiple drive ends formed on the transmission member. The drive member drives the transmission member to move, causing each drive end to output power. This design reduces the number of drive members and simplifies the structure. Alternatively, the drive assembly 13 can include multiple drive members, each with a drive end formed on it. Each drive member outputs power through its corresponding drive end. This design allows each drive member to work independently, facilitating adjustments to the number of drive members activated as needed, and providing high flexibility in adjustment.

[0029] It should be noted that the drive end drives the stirring element 12 in a non-contact manner, meaning the drive end and the stirring element 12 do not need to be in direct contact. Therefore, the drive assembly 13 can be located on the outside of the storage tank 11 without penetrating into the receiving cavity 111, eliminating the need for openings in the bottom wall of the storage tank 11 and maintaining the structural integrity of the bottom wall. To achieve non-contact drive, one approach is to use magnetic drive. Specifically, the drive assembly 13 can be configured to generate magnetic attraction, and the stirring element 12 can be equipped with a corresponding magnet or a ferromagnetic metal component. Under the influence of magnetic attraction, they attract each other, and when the drive assembly 13 moves, it drives the stirring element 12 to move synchronously, enabling the stirring element 12 to agitate the material within the receiving cavity 111.

[0030] Another embodiment of driving the stirring element 12 with the drive component 13 can be achieved by electromagnetic induction. Specifically, the drive component 13 can be configured to generate a changing magnetic field, and the stirring element 12 can be configured to be conductive. When the drive component 13 is activated and generates a changing magnetic field, according to the principle of electromagnetic induction, the stirring element 12 generates an induced current, causing it to move under the influence of an Ampere force in the magnetic field. This achieves contactless driving of the stirring element 12 by the drive component 13. The specific design schemes of the drive component 13 and the stirring element 12 will be described in detail in the following embodiments.

[0031] The stirring device 1 provided in this embodiment includes a storage tank 11, stirring elements 12, and a drive assembly 13. The storage tank 11 has a receiving cavity 111 for storing the raw materials to be stirred. By arranging multiple stirring elements 12 at intervals within the receiving cavity 111, each stirring element 12 can stir the raw materials in different areas of the receiving cavity 111, thereby effectively increasing the stirring range, reducing dead zones, and improving the uniformity of stirring. By movably connecting each stirring element 12 to the bottom wall of the storage tank 11, the stirring elements 12 can stir at the bottom of the receiving cavity 111, which can better prevent the raw materials to be stirred from settling at the bottom. Even if settling occurs, the stirring action of the stirring elements 12 can drive the raw materials to mix, thereby improving the utilization rate and the quality of the raw material mixture. Meanwhile, by equipping the drive assembly 13 with multiple drive ends, each drive end drives the corresponding stirring element 12 in a non-contact manner, the drive assembly 13 does not need to be inserted into the receiving cavity 111, and the bottom wall of the storage tank 11 does not need to be perforated. This maintains the structural integrity of the bottom wall of the storage tank 11, simplifies the manufacturing process, reduces frictional losses caused by direct contact between the drive assembly 13 and the stirring element 12, and improves the efficiency of energy transfer. Furthermore, the one-to-one correspondence between multiple drive ends and each stirring element 12 improves the precision of the motion control of the stirring element 12, which is beneficial to improving the stirring effect.

[0032] In some embodiments, such as Figure 3 and Figure 4 As shown, the drive assembly 13 includes a mounting frame 131 and a plurality of drive units 132, each corresponding to one of the stirring components 12. Each drive unit 132 is connected to the mounting frame 131 and electrically connected to an external power source. Each drive unit 132 has a drive end, and the movement direction of at least one drive unit 132 is different from the movement direction of the other drive units 132.

[0033] Specifically, the mounting bracket 131 is used to mount each drive unit 132 and connects it to the storage box 11 or an external device (such as the frame of a cooking machine), thereby fixing the position of the drive unit 132. To control the drive unit 132, each drive unit 132 is typically connected to a power supply and also to related control devices. Optionally, the control scheme for the drive unit 132 can be to control each drive unit 132 independently, allowing for selection of the number of drive units 132 activated or adjustment of the speed of each drive unit 132 as needed, providing high flexibility. Alternatively, all drive units 132 can be controlled uniformly, or the drive units 132 can be divided into multiple groups, with each group controlled independently, depending on the specific requirements.

[0034] The above embodiment employs multiple driving units 132 corresponding one-to-one with the stirring element 12. Each driving unit 132 drives the corresponding stirring element 12 to move. Combined with the control scheme design for the driving units 132, it is possible to flexibly control the number of driving units 132 to be started and adjust the speed of each driving unit 132 as needed, achieving high adjustment flexibility and more precise control effects. Simultaneously, by employing a method where the movement direction of some driving units 132 is different from that of others, and the movement direction of the stirring element 12 corresponding to the driving units 132 with opposite movement directions is also opposite, the flow state of the liquid within the containing cavity 111 becomes more turbulent, which is beneficial for the thorough mixing of various raw materials and further improves the uniformity of stirring.

[0035] In some embodiments, such as Figure 3 and Figure 4 As shown, the mounting bracket 131 has a hollow interior forming a mounting cavity 1311, and at least a portion of each drive unit 132 is disposed within the mounting cavity 1311. In this way, the mounting bracket 131 not only meets the positional fixation requirements of each drive unit 132 during installation, but also covers and protects the portion of the drive unit 132 assembled within the mounting cavity 1311, effectively avoiding direct contact and improving reliability. Furthermore, in terms of appearance, only the mounting bracket 1311 is visible, resulting in a clean and tidy appearance.

[0036] The phrase "at least a portion of each drive unit 132 is disposed within the mounting cavity 1311" as mentioned above means that, provided the agitator 12 can be reliably driven to move, either all of the drive units 132 can be disposed within the mounting cavity 1311, or only a portion of their structure can be disposed within the mounting cavity 1311. In short, the assembled drive unit 132 has a portion of its structure disposed within the mounting cavity 1311, thereby satisfying the installation requirements.

[0037] In some embodiments, such as Figure 2 and Figure 4 As shown, the drive unit 132 includes a motor 1321 and a magnetic component 1322. The motor 1321 is connected to the mounting bracket 131 and electrically connected to an external power source. The motor 1321 has an output shaft 1321a, and the magnetic component 1322 is connected to the output shaft 1321a and located near the bottom of the storage tank 11, with the drive end located on the magnetic component 1322. The motor 1321 drives the magnetic component 1322 to rotate around the axis of the output shaft 1321a via the output shaft 1321a, thereby driving the stirring component 12 to rotate synchronously and achieve the stirring function.

[0038] Specifically, when the magnetic component 1322 is a permanent magnet and the stirring component 12 is a ferromagnetic metal component or a permanent magnet, the stirring component 12 and the magnetic component 1322 are held in a mutually attractive state under the action of magnetic attraction. When the magnetic component 1322 rotates around the axis of the output shaft 1321a, it will drive the stirring component 12 to rotate synchronously. This contactless transmission not only reduces the complexity of the transmission structure, but also allows the magnetic component 1322 and the stirring component 12 to separate when the resistance experienced by the stirring component 12 is greater than the magnetic attraction force. This prevents the motor 1321 from stalling and improves the reliability of the motor 1321.

[0039] In another embodiment, the magnetic component 1322 and the stirring component 12 are driven by electromagnetic induction. When the magnetic component 1322 rotates around the axis of the output shaft 1321a, the magnetic field around the magnetic component 1322 changes. According to the principle of electromagnetic induction, the changing magnetic field induces a current in the stirring component 12, causing the stirring component 12 to move under the action of the Ampere force in the magnetic field. During this process, the magnetic component 1322 does not need to contact the stirring component 12, achieving contactless driving of the stirring component 12. To avoid collision and friction between the magnetic component 1322 and the bottom of the storage tank 11 during movement, the magnetic component 1322 is usually spaced apart from the bottom wall of the storage tank 11, thereby preventing direct contact between the magnetic component 1322 and the storage tank 11 and ensuring smooth movement of the magnetic component 1322.

[0040] It is understood that the magnetic component 1322 can consist solely of a magnetic structure, or it can be a component containing both magnetic and non-magnetic structures, as long as it can generate a magnetic field. For example, in one embodiment, the magnetic component 1322 includes a bracket 1322a and a magnet 1322b. The magnet 1322b is mounted on the bracket 1322a, which is connected to the output shaft 1321a. The driving end is the end of the bracket 1322a facing the bottom of the storage box 11, and the driving end is spaced apart from the bottom of the storage box 11. The magnet 1322b can be a permanent magnet or an electromagnet. This design eliminates the need to make the entire magnetic component 1322 from magnetic materials, thus reducing the material cost of the magnet 1322b. The connection between the magnet 1322b and the bracket 1322a can also be detachable, using adhesive, snap-fit, or screw connections, facilitating replacement when the magnet 1322b's magnetism weakens due to long-term use.

[0041] The above embodiment uses a motor 1321 to drive the magnetic component 1322, cleverly utilizing the principle of electromagnetic induction to achieve contactless driving of the stirring component 12. This reduces frictional losses between the magnetic component 1322 and the stirring component 12, improving energy transfer efficiency. Simultaneously, since there is no contact friction, frictional noise during the driving of the stirring component 12 is avoided, and the vibration generated by the motor 1321 is not transmitted to the stirring component 12, resulting in smooth movement and less noise, thus enhancing the user experience.

[0042] In some embodiments, such as Figure 2 and Figure 4 As shown, the drive assembly 13 also includes a fixing plate 133, which is connected to the mounting bracket 131. Each motor 1321 is connected to the fixing plate 133. Specifically, the fixing plate 133 is used to install and fix the motors 1321. Connection positions can be set on the fixing plate 133 according to the number and position of the motors 1321, and the housing of the motors 1321 is fixed to the connection positions of the fixing plate 133 by screws, rivets and other connecting parts.

[0043] By adopting the above design, during assembly, each motor 1321 can be connected to the fixing plate 133 in sequence. After the cables connecting the motor 1321 and the power supply are organized, the fixing plate 133 and the motor 1321 are connected to the mounting bracket 131 as a whole. The assembly steps are clear and the operation is simple. Furthermore, when the motor 1321 is connected to the fixing plate 133, the fixing plate 133 occupies less space and will not affect the cable wiring operation, which helps to improve assembly efficiency.

[0044] Optionally, to facilitate the mounting of multiple motors 1321 on the fixing plate 133, a deformation groove 1331 can be provided on the fixing plate 133 at the mounting hole corresponding to each motor 1321. When installing the motor 133, the deformation groove 1331 can be deformed to meet the installation requirements of the motor 133, making it easier for the motor 133 to be inserted into the mounting hole and clamped, thus improving the stability of the installation.

[0045] To ensure waterproofing while allowing the motor 1321 to connect to the power supply, a cable passage hole can be made on the mounting bracket 131 for the cable to pass through, and a sealing joint 134 can be installed at the cable passage hole to waterproof and seal the position where the cable passes through the mounting bracket 131.

[0046] In some embodiments, such as Figure 2As shown, the drive assembly 13 also includes a support member 134. The support member 134 supports the fixing plate 133, with one end of the support member 134 fixed to the bottom of the mounting bracket 131, and the fixing plate 133 connected to the other end of the support member 134. Specifically, the support member 134 can be a rod-shaped member of a certain length, thereby allowing a corresponding distance between the fixing plate 133 and the bottom of the storage box 11. The space formed by this distance is used for the installation and placement of the motor 1321. In this configuration, the spacing of the fixing plate 133 allows the magnetic element 1322 to be located between the fixing plate 133 and the bottom of the storage box 11, while the motor 1321 is located between the fixing plate 133 and the bottom wall of the mounting bracket 131. That is, the storage box 11 and the motor 1321 are located on opposite sides of the fixing plate 133, resulting in a compact overall structure. Moreover, the motor 1321 is isolated and protected by the fixing plate 133, further protecting it and improving the reliability of use.

[0047] In some embodiments, the inner wall of the storage tank 11, which forms the receiving cavity 111, is provided with a turbulent structure to disrupt the movement direction of the raw material to be stirred. Specifically, the turbulent structure can be an inwardly protruding structure on the inner wall of the storage tank 11. Multiple turbulent structures can be provided, and the shapes of each turbulent structure can be the same or different. It is understood that there are no specific limitations on the shape and arrangement of the turbulent structure, as long as it can make the inner wall surface of the storage tank 11 uneven, thereby disrupting the flow direction when the liquid flows.

[0048] The above embodiment, by setting a turbulent flow structure, when the liquid in the receiving cavity 111 is stirred by the stirring member 12 and flows, the liquid flowing over the inner wall surface of the storage tank 11 changes its flow direction by colliding with the turbulent flow structure, so that the liquid at different positions flows in different directions, promotes the full mixing of each raw material, and helps to improve the uniformity of stirring.

[0049] In some embodiments, such as Figure 2 and Figure 4As shown, the stirring component 12 includes a fixed shaft 121 and a stirring wheel 122. One end of the fixed shaft 121 is fixed to the bottom wall of the storage tank 11, and the other end of the fixed shaft 121 extends vertically as a free end. The stirring wheel 122 is used to rotate and stir the material in the receiving cavity 111. The stirring wheel 122 has a shaft hole 1221, and the fixed shaft 121 passes through the shaft hole 1221. Specifically, during assembly, the shaft hole 1221 on the stirring wheel 122 is aligned with the free end of the fixed shaft 121, so that the free end can pass into the shaft hole 1221, allowing the stirring wheel 122 to rotate around the fixed shaft 121. Furthermore, a limiting member 123 is connected to the free end, which limits the position of the stirring wheel 122 movably sleeved on the fixed shaft 121. In this way, under the limitation of the limiting member 123, the stirring wheel 122 can be prevented from detaching from the fixed shaft 121, ensuring the stability of the stirring function. The limiting component 123 can be a limiting pin or a snap ring, etc., with a simple structure and good limiting reliability.

[0050] In some embodiments, such as Figure 5 As shown, as another implementation of the stirring device 1, the stirring device 1 can be further configured to include a partition 14, which is disposed within the receiving cavity 111 and connected to the storage tank 11. An installation space 141 corresponding to each stirring element 12 is formed between the partition 14 and the storage tank 11. Each stirring element 12 is disposed within a different installation space 141. The partition 14 has multiple through holes communicating with the receiving cavity 111 and the installation spaces 141.

[0051] Specifically, the separator 14 is installed on the bottom wall of the storage tank 11, forming the receiving cavity 111. A portion of the separator 14 protrudes away from the bottom wall, creating an installation space 141 between the separator 14 and the bottom wall. To connect the receiving cavity 111 and the installation space 141, multiple through holes 142 are formed in the separator 14, allowing the stirring member 12 to move, causing the liquid to flow back and forth between the installation space 141 and the receiving cavity 111, thereby achieving a stirring effect. Optionally, the separator 14 can have a mesh structure, with the through holes 142 being the mesh openings. The separator 14 can be installed and fixed using screws or other connectors, allowing it to be disassembled for maintenance, making maintenance convenient.

[0052] In the above embodiment, by setting a separator 14, the agitator 12 is installed in the installation space 141 formed between the separator 14 and the storage tank 11. The separator 14 can block solid raw materials in the raw materials to be mixed, reduce the problem of solid raw materials depositing and adhering to the agitator 12 and affecting the performance of the agitator 12, thereby reducing the burden of cleaning and maintaining the agitator 12.

[0053] Understandably, since there are multiple stirring components 12, it is necessary to ensure that there is a certain gap between each stirring component 12 and the partition 14 to prevent interference between the stirring component 12 and the partition 14 during movement. Therefore, the installation accuracy of the partition 14 is required to be high. In order to achieve accurate positioning and installation of the partition 14 and improve the convenience of positioning, in some embodiments, the stirring device 1 also includes a positioning component, which is connected to the storage tank 11 and / or the mounting bracket 131. The positioning component is used at least to position the installation position of the partition 14.

[0054] Specifically, the positioning element can take various forms. For example, it can be a positioning post, with one end connected to the bottom wall of the storage box 11 forming the receiving cavity 111, and the other end extending towards the opening of the storage box 11. The partition 14 can have corresponding positioning holes, which cooperate with the positioning post. Guided by the positioning post, the partition 14 slides to the bottom of the storage box 11 and is fixed, thus completing the accurate installation of the partition 14. Similarly, the positioning element can also be a guide rail, a slide, or other guiding structure. It is only necessary to provide a corresponding guiding structure on the partition 14 that is compatible with the positioning element.

[0055] In some embodiments, the positioning element is a magnetic strip. The magnetic strip applies a magnetic force to the separator 14 to position the separator 14 in its installation position. Optionally, the magnetic strip can be disposed on the bottom wall of the storage box 11, or on the side of the mounting bracket 131 facing the bottom wall of the storage box 11, or connected between the storage box 11 and the mounting bracket 131, allowing for flexible installation. When a magnetic strip is used as the positioning element, a magnetic structure that can be subjected to magnetic force is simply provided on the separator 14 at the position corresponding to the magnetic strip. During installation of the separator 14, the separator 14 gradually approaches the magnetic strip, causing the magnetic strip to apply a magnetic force to the magnetic structure on the separator 14, thereby attracting the separator 14 to the desired installation position and achieving the positioning function of the separator 14.

[0056] In the above embodiments, the positioning element is in the form of a magnetic strip, which does not require direct contact with the partition 14 and can be positioned by magnetic force alone. Moreover, compared with positioning posts, guide rails, etc., the magnetic strip positioning element does not need to be installed in the receiving cavity 111, does not occupy the space of the receiving cavity 111, can increase the volume of the receiving cavity 111, and the positioning element is not easily contaminated by the liquid in the receiving cavity 111, which helps to reduce the burden of cleaning and maintenance.

[0057] like Figure 6As shown, this application embodiment also provides a liquid conveying system 2, including the aforementioned stirring device 1, conveying pipe 21, and conveying pump 22. One end of the conveying pipe 21 is inserted into the storage tank 11, and the other end extends to the target position for conveying the liquid. The conveying pump 22 is connected to the conveying pipe 21 and is used to draw the stirred liquid from the storage tank 11 and output it to the target position via the conveying pipe 21. To facilitate normal liquid intake when the remaining liquid is low, the end of the conveying pipe 21 inserted into the storage tank 11 can extend to the bottom of the receiving cavity 111. It is understood that the liquid conveying system 2 can be used alone to assist in adding liquid during manual cooking. Of course, the liquid conveying system 2 can also be integrated into cooking equipment such as a stir-fry machine to automatically add liquid according to the program instructions of the cooking equipment during the cooking process.

[0058] The liquid material conveying system 2 provided in this application embodiment can achieve a better stirring effect and high stirring uniformity of liquid material by adopting the above-mentioned stirring device 1. After stirring is completed, the stirred liquid material is conveyed to the target position through the conveying pipe 21 by the suction action of the conveying pump 22, thereby realizing the automation of liquid material stirring and conveying and improving the convenience of food preparation.

[0059] like Figure 7 As shown in the figure, this application embodiment also provides a cooking machine 3, including a main body 31, a pot body 32 and the above-mentioned liquid conveying system 2. The pot body 32 and the liquid conveying system 2 are both connected to the main body 31. The liquid conveying system 2 draws and conveys the stirred liquid to the pot body 32.

[0060] Understandably, the cooking machine 3 can also be equipped with multiple liquid storage devices for storing different liquids, such as cooking wine and light soy sauce. When the liquids stored in the liquid storage devices need to be stirred, these devices can be designed with reference to the stirring device 1 described above. The number of stirring elements 12 in the liquid storage devices can be flexibly designed according to actual conditions and is not limited to at least two. When liquid storage devices are provided, each liquid storage device can also be connected to a conveying pipe 21, and a conveying pump 22 can be connected to the conveying pipe 21 to realize the automatic addition of multiple liquids.

[0061] The cooking machine 3 provided in this application embodiment, by integrating the above-mentioned liquid conveying system 2, can realize the automatic stirring and conveying of mixed liquids such as thickening sauce, and the uniformity of liquid stirring is high. During the automatic cooking process of the dishes, the required liquids are added in time, which better meets the needs of the cooking process of dishes such as thickening sauce, and improves the quality and appearance of the dishes cooked by the cooking machine.

[0062] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, and improvements made within the spirit and scope of this application are included within the scope of protection of this application.
