The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Please see Figure 1 This application provides a food processing device 100 for processing food, such as having functions for stirring and / or breaking down food. The food processing device 100 can be a meat grinder, ice cream machine, slush machine, cooking machine, etc., and this embodiment does not impose specific limitations. For ease of description, this embodiment uses an ice cream machine as an example to illustrate the food processing device 100.

[0026] Please see Figures 2-3In one embodiment provided in this application, the food processing device 100 includes a receiving container 10, a food processing blade 20, a first drive mechanism 30, a second drive mechanism 40, a transmission shaft 50, and a cleaning assembly 60. The receiving container 10 has a food cavity 11, and the food processing blade 20 is disposed within the food cavity 11. The first drive mechanism 30 is connected to the food processing blade 20 to drive the food processing blade 20 to rotate. The second drive mechanism 40 is disposed outside the receiving container 10, and the transmission shaft 50 is disposed within the food cavity 11 and is drively connected to the second drive mechanism 40. The cleaning assembly 60 is detachably connected to the transmission shaft 50 and has bristles 601. When the cleaning assembly 60 is installed on the transmission shaft 50 and located within the food cavity 11, the bristles 601 contact the food processing blade 20.

[0027] During cleaning, the user installs the cleaning component 60 inside the food processing chamber 11 and connects it to the drive shaft 50. The drive shaft 50 is located inside the food processing chamber 11 and is connected to the second drive mechanism 40. Driven by the drive shaft 50 and the second drive mechanism 40, the cleaning component 60 can automatically clean the container 10, improving cleaning efficiency. Furthermore, the cleaning component 60 is detachable for easy cleaning and maintenance. The cleaning component 60 is further equipped with bristles 601. When the cleaning component 60 is installed inside the food processing chamber 11, the bristles 601 contact the food processing blades 20. That is, the bristles 601 rotate under the drive of the second drive mechanism 40 and contact the food processing blades 20 to clean them. This eliminates the need for manual removal to clean the food processing blades 20, enhancing the equipment's intelligence and further improving cleaning efficiency. In this embodiment, the food processing blade 20 is also connected to the first drive mechanism 30 to achieve simultaneous rotation with the cleaning component 60, thereby increasing the relative contact with the cleaning component 60 and eliminating cleaning dead angles, which can more effectively remove food residues and stains on the food processing blade 20, and further improve the cleaning efficiency of the equipment.

[0028] The following sections will introduce each component of the food processing equipment 100 and the specific structure of each component.

[0029] Please see Figure 1 and Figure 3The housing 101 is used to install and protect components, and also serves to support the food processing equipment 100 in its place of use, such as on the ground, tabletop, or other support platform. Specifically, the housing 101 is generally rectangular, but in other embodiments, it can also be any shape, such as cube, cylinder, or even irregular. The housing 101 has a receiving space for installing and placing components, which may include the aforementioned receiving container 10, food processing blade 20, first drive mechanism 30, second drive mechanism 40, drive shaft 50, cleaning assembly 60, etc.

[0030] Please see Figure 2 and Figure 3 The container 10 is a mechanism within the food processing equipment 100 used to hold ingredients to be processed. The container 10 is housed within the casing 101 and is used to provide a low-temperature environment for ice cream. Specifically, the container 10 may include an inner container (not shown) and an outer container (not shown), both of which are barrel-shaped structures, forming a double-walled structure that effectively maintains the temperature required for food processing (e.g., a low-temperature environment). The inner container is typically made of food-grade metal to ensure food safety and hygiene. The outer container may be made of plastic or other materials to provide good insulation. An insulating material (not shown), such as polyurethane foam, may be filled between the inner and outer containers to aid insulation and reduce the impact of external heat on the internal temperature of the food processing equipment 100.

[0031] The container 10 has an ingredient cavity 11 for holding ingredients needed to make ice cream, specifically cream, butter, cheese, nuts, fruits, etc. It is understood that when the food processing equipment 100 is used for other purposes, the ingredients in the ingredient cavity 11 can also be grains, meat products, etc. When the container 10 is a fixed, non-removable structure, the ingredient cavity 11 is specifically defined by the inner wall surface 14 of the inner container; when the container 10 is a detachable structure, it can include an inner liner 12 and a mounting container 13, with the inner liner 12 detachably disposed within the mounting container 13 for easy access and placement of ingredients. In this case, the internal space of the inner liner 12 serves as the ingredient cavity 11. The inner liner 12 has an opening through which ingredients enter the ingredient cavity 11 for food processing.

[0032] The food processing process can involve churning or breaking up ice cream. In this embodiment, the food processing blade 20 is located at the bottom of the food cavity 11, and specifically, it can be a wall-breaking blade. It is used to break up larger or harder foods within the food cavity 11 under the drive of the first driving mechanism 30. The food processing blade 20 can be fixedly connected to the first driving mechanism 30 or detachably connected to it; this embodiment does not impose specific limitations. As an example only, the food processing blade 20 is detachably connected to the first driving mechanism 30 to facilitate maintenance and management.

[0033] This embodiment does not limit the specific structure of the food processing knife 20; the food processing knife 20 is adapted to common high-speed blending knives. As an example only, the food processing knife 20 may include a blending blade 21 and a rotating shaft 22. The rotating shaft 22 connects the blending blade 21 and the first drive mechanism 30, so that the blending blade 21 can rotate under the drive of the first drive mechanism 30. More specifically, the first drive mechanism 30 is disposed outside the receiving container 10. The first drive mechanism 30 may include a transmission member 31 and a drive member 32 connected to the transmission member 31. The drive member 32 may be a drive motor. The transmission member 31 at least partially protrudes into the food cavity 11 and is detachably connected to the rotating shaft 22.

[0034] In this embodiment, there can be multiple blending blades 21, which are detachably connected to the rotating shaft 22 for easy replacement or cleaning. In some embodiments, the distances between the multiple blending blades 21 and the bottom wall 142 of the container 10 are different, which can achieve a certain stirring effect and cut and crush the food in different areas, improving the cutting and crushing effect of the food processing blade 20 on the food. In other embodiments, the angles between the multiple blending blades 21 and the rotating shaft 22 are different. Specifically, the angle between one of the blending blades 21 and the axis of the rotating shaft 22 is approximately 180°, that is, approximately parallel to the bottom wall 142 of the container 10. The angle between one of the blending blades 21 and the axis of the rotating shaft is less than 90°, thereby enabling the cutting and crushing of the food in different areas. It should be noted that this embodiment does not impose a specific limit on the number of blades of the food processing knife 20. The number of the wall-breaking blades 21 mentioned above can be two or more. In some embodiments, the food processing knife 20 may also include one wall-breaking blade 21. Different numbers of wall-breaking blades 21 can be installed according to actual needs.

[0035] To improve processing efficiency, in this embodiment, the food processing device 100 may include a stirring blade 70 to facilitate stirring of the ice cream. Specifically, the stirring blade 70 is connected to a drive shaft 50, which is disposed within the food chamber 11 and is driveably connected to a second drive mechanism 40. Thus, the stirring blade 70 can rotate under the drive of the drive shaft 50 and the second drive mechanism 40 to stir the food within the container 10. Specifically, the drive shaft 50 is rod-shaped and connects the second drive mechanism 40 and the stirring blade 70. The second drive mechanism 40 is disposed outside the container 10, specifically at the opening of the container 10, and together with the lid, seals the opening to prevent dust and impurities from entering the food chamber 11. The second drive mechanism 40 drives the drive shaft 50 to rotate, thereby driving the cleaning component 60 and the stirring blade 70 to rotate. This embodiment does not limit the type of the second drive mechanism 40; for example, it may be a drive motor, a cylinder, etc.

[0036] In this embodiment, the drive shaft 50 can be fixedly connected to the second drive mechanism 40 or detachably connected to the second drive mechanism 40; this embodiment does not impose specific limitations on this. When the stirring blade 70 is located in the food chamber 11, the stirring blade 70 is connected to the end of the drive shaft 50 away from the second drive mechanism 40 and is coaxial with and spaced apart from the food processing blade 20 to ensure that the food processing blade 20 has sufficient space for cell wall breaking. In this embodiment, the stirring blade 20 and the drive shaft 50 are coaxially arranged. This embodiment does not limit the specific connection method between the stirring blade 70 and the drive shaft 50. For example, the stirring blade 70 can be detachably connected to the drive shaft 50, specifically by using a magnetic connection or a plug-in connection. In other embodiments, the stirring blade 20 and the drive shaft 40 can be integrally formed.

[0037] Please see Figure 3 and Figure 4As an example, the stirring blade 70 may specifically include a connecting portion 71 and a stirring blade 72 connected to each other. The connecting portion 71 is used to connect to the drive shaft 50 and extends radially along the drive shaft 50. The connecting portion 71 may specifically be a groove or a connecting sleeve, which can be fitted onto the drive shaft 50 to achieve a fixed connection with the drive shaft 50. The stirring blade 72 is the main component of the stirring blade 70 used for stirring. The stirring blade 72 may include multiple stirring elements to improve stirring efficiency. When the stirring blade 70 is installed in the food cavity 11, the stirring blade 72 may be located at the end of the connecting portion 71 away from the drive shaft 50. The distance between adjacent stirring elements and the bottom of the food cavity 11 may be different, thereby enabling the stirring and mixing of food in different areas to improve the stirring effect. It is understood that in some embodiments, the stirring blade 72 may also include only one stirring element, which can also stir the food in the food cavity 11 under the drive of the drive shaft 50 and the second drive mechanism 40.

[0038] During the process of breaking down food ingredients by the food processing blade 20, some ingredients will adhere to the food processing blade 20. In order to achieve automatic cleaning of the food processing blade 20 and improve cleaning efficiency, in this embodiment, the cleaning component 60 is provided with bristles 601. When the cleaning component 60 is installed on the drive shaft 50 and located in the food cavity 11, the bristles 601 contact the food processing blade 20 to achieve automatic cleaning.

[0039] Please see Figures 3-5 Specifically, the cleaning component 60 is detachably connected to the drive shaft 50, so that when the first drive mechanism 30 drives the drive shaft 50 to rotate, the cleaning component 60 can clean the food processing blade 20. It should be noted that when the food processing equipment 100 includes the aforementioned stirring blade 70, and the stirring blade 70 is sleeved outside the drive shaft 50, the cleaning component 60 can be connected to either the stirring blade 70 or the drive shaft 50, and can rotate under the drive of the first drive mechanism 30. That is, the stirring blade 70 can be considered equivalent to the drive shaft 50, or the cleaning component 60 can be considered to be indirectly mounted on the drive shaft 50 through the stirring blade 70.

[0040] In this embodiment, the cleaning component 60 may include a first cleaning brush 61, which may be mounted on the end of the drive shaft 50 facing the food processing blade 20, so as to contact and rotate with the wall-breaking blade 21 in the first drive mechanism 30. Specifically, the end of the drive shaft 50 opposite to the first drive mechanism 30 is provided with a mounting portion 51, and the first cleaning brush 61 is provided with a mating portion 611, which is detachably connected to the mounting portion 51. This embodiment does not limit the specific structure of the mounting portion 51 and the mating portion 611. For example, either the mounting portion 51 or the mating portion 611 may be a magnetic element, and the other may be a magnetic suction element; either the mounting portion 51 or the mating portion 611 may be a groove, and the other may be a protrusion. As a specific example, the mating portion 611 may be a protrusion, and the mounting portion 51 may be a groove. To further improve the connection strength, in some embodiments, the contact surfaces of the mounting portion 51 and the mating portion 611 may also be provided with a threaded connection structure, and the two are detachably connected through the threaded connection structure.

[0041] Please see Figure 4 and Figure 5 In this embodiment, the first cleaning brush 61 includes a first bristle support 612, which is detachably connected to the drive shaft 50 via a mating part 611 to fix the first cleaning brush 61. The first bristle support 612 is also used to mount bristles 601, so that the bristles 601 can contact the food processing knife 20. Specifically, the first bristle support 612 may include a connecting plate 6121 and two brush plates 6122, both of which are plate-shaped. The two brush plates 6122 are spaced apart from each other, and the bristles 601 are disposed on the two brush plates 6122, specifically mounted on the side of the brush plates 6122 facing the food processing knife 20. When the first cleaning brush 61 is mounted on the drive shaft 50, the food processing knife 20 is approximately located between the two brush plates 6122. A mating part 611 is disposed on a connecting plate 6121, which connects the two brush plates 6122 and together forms a clearance space 6123. The brush bristles 601 are disposed on the side of the two brush plates 6122 facing the clearance space 6123. The clearance space 6123 accommodates the food processing blade 20 so that the brush bristles 601 can contact the cell-wall breaking blade 21 of the food processing blade 20. Thus, driven by the first drive mechanism 30 and the transmission shaft 50, the first cleaning brush 61 can automatically clean the cell-wall breaking blade 21. In some embodiments, the brush bristles 601 can be distributed in multiple rows along the extension direction of the brush plate 6122 to increase the distribution area of ​​the brush bristles 601. The spacing between adjacent brush bristles 601 is small to increase the contact area between the brush bristles 601 and the cell-wall breaking blade 21, thereby cleaning more effectively and ensuring cleaning results.

[0042] Furthermore, in some embodiments, to further improve the cleaning effect of the food processing blade 20, the bristles 601 can extend into the installation gap 201 between the food processing blade 20 and the receiving container 10 to achieve further automatic cleaning of the food processing blade 20. Specifically, the wall-breaking blade 21 and the bottom wall 142 of the receiving container 10 are spaced apart to form an installation gap 201. After passing through the gap between adjacent wall-breaking blades 21 from the brush plate 6122, some bristles 601 protrude into the installation gap 201 and contact the wall-breaking blade 21. In some embodiments, the wall-breaking blade 21 may also have a clearance channel for the bristles 601 to pass through, facilitating contact between the bristles 601 and the installation gap 201.

[0043] By setting the first cleaning brush 61, the bristles 601 can contact the food processing blade 20 and extend into the installation gap 201 to contact the blending blade 21. This allows for cleaning of the blending blade 21 without manual removal, resulting in better cleaning efficiency and effect. It automates the cleaning of the food processing blade 20, improving the user experience and the intelligence of the food processing equipment 100. It should be noted that when the first cleaning brush 61 automatically cleans the food processing blade 20, the blending blade 21 can be stationary or rotating. As an example, when the bristles 601 clean the food processing blade 20, the blending blade 21 rotates under the drive of the first drive mechanism 30, increasing contact with the cleaning component 60 and more effectively removing food residue and stains from the food processing blade 20, further improving the cleaning efficiency of the equipment.

[0044] Please see Figure 4 and Figure 6 Since food particles will adhere to the inner wall 14 of the container 10 during food processing, in order to achieve automatic cleaning of the inner wall 14 of the food container, the cleaning component 60 may also include a second cleaning brush 62. The second cleaning brush 62 is detachably connected to the stirring blade 72 and can rotate relative to the inner wall 14 of the container 10 under the drive of the second drive mechanism 40.

[0045] Specifically, the second cleaning brush 62 includes a second bristle support 621, which is used to detachably connect the second cleaning brush 62 to the stirring blade 72 for easy maintenance and cleaning. In this embodiment, the stirring blade 72 may include a support plate 721 and a scraper 722. The support plate 721 serves as a support structure for the stirring blade 72 and is connected between the connecting portion 71 and the scraper 722. When the stirring blade 70 is connected to the second drive mechanism 40, it drives the scraper 722 to rotate around the connecting portion 71, ensuring that the cleaning assembly 60 can thoroughly clean the food cavity 11. The support plate 721 may extend radially along the connecting portion 71. For example, when the stirring blade 70 is installed in the food cavity 11, the support plate 721 extends toward the inner wall surface 14 of the food cavity 11 and is spaced apart from the inner wall surface 14 of the food cavity 11. The scraper 722 is disposed at the end of the support plate 721 away from the connecting portion 71 so as to fully stir the food in the food cavity 11. In this embodiment, there can be multiple support plates 721, which are arranged sequentially and at intervals around the outer periphery of the connecting part 71 and connected between the connecting part 71 and the scraper 722, respectively. This embodiment does not limit the specific number of support plates 721 or the connection position between each support plate 721 and the connecting part 71, and can set them according to actual usage requirements.

[0046] The scraper 722 is a component of the stirring blade 70 used for stirring. The scraper 722 is generally plate-shaped and extends towards the bottom of the food container 11. In this embodiment, the second cleaning brush 62 can be connected to the scraper 722 and cleans the inner wall surface 14 of the container 10 under the drive of the second driving mechanism 40. The second cleaning brush 62 may include a second bristle support 621, which is generally plate-shaped and can be connected to the side of the scraper 722 facing the inner wall surface 14 of the food container. For example, the second bristle support 621 is provided with a snap-fit ​​(not shown in the figure), which can snap onto the slot (not shown in the figure) of the scraper 722. In other embodiments, the second bristle support 621 can also be sleeved on the scraper 722. The second cleaning brush 62 has bristles 601 densely packed on one side. When the cleaning component 60 is installed inside the food cavity 11, the bristles 601 can extend towards and contact the inner wall surface 14 of the food container. The bristles 601 are used to follow the rotation of the stirring blade 70 and the drive shaft 50, and scrape or absorb the food adhering to the inner wall surface 14 of the container 10 during the rotation. The bristles 601 can be distributed in multiple rows along the axial direction of the second bristle support 621 to increase the distribution area of ​​the bristles 601. Adjacent bristles 601 can be staggered to increase the contact area between the bristles 601 and the inner wall surface 14 of the food cavity 11 and avoid missing cleaning areas, thereby cleaning more effectively and ensuring cleaning results.

[0047] It should be noted that the number of second cleaning brushes 62 can be one or more, and the number of scrapers 722 can also be one or more; this embodiment does not impose specific limitations on this. For example, when there is one scraper 722, one second cleaning brush 62 is connected to the scraper 722 and rotates with the connecting part 71 of the stirring blade 70 and the drive shaft 50. In this embodiment, there are two scrapers 722, which are spaced apart and located on both sides of the connecting part 71 / drive shaft 50. Each scraper 722 is connected to the connecting part 71 through a support plate 721, and one second cleaning brush 62 can be installed on each scraper 722 to improve cleaning efficiency. It is understood that in some other embodiments, the number of scrapers 722 can also be three, four, five, or other numbers, and one second cleaning brush 62 can be provided on each scraper 722 to improve cleaning efficiency.

[0048] The aforementioned inner wall surface 14 can be understood as the inner wall 141 and bottom wall 142 of the receiving container 10. The inner wall 141 is arranged in a circumferential manner and connected to the bottom wall 142, and the two together define the food cavity 11. Brush bristles 601 are at least distributed on the side of the second bristle support 621 facing the inner wall 141 and the bottom wall 142 of the food cavity 11, and are in contact with the inner wall 141 and the bottom wall 142. Specifically, in this embodiment, the second bristle support 621 includes a first mounting portion 6211 and a second mounting portion 6212. The first mounting portion 6211 is located on the side of the second bristle support 621 near the inner wall 141 of the food cavity 11 to clean the inner wall 141, and the first mounting portion 6211 extends substantially along the axial direction of the connecting portion 71. Specifically, when the second cleaning brush 62 is located inside the food cavity 11, the first mounting portion 6211 can extend to the bottom of the food cavity 11, and the bristles 601 are distributed on the side of the first mounting portion 6211 facing the inner wall 141 and contacting the inner wall 141. Further, the second mounting portion 6212 is connected to the end of the first mounting portion 6211 near the bottom wall 142 and extends radially along the connecting portion 71. When the second cleaning brush 62 is located inside the food cavity 11, the second mounting portion 6212 is located at the bottom of the food cavity 11 and is substantially parallel to the bottom wall 142 of the receiving container 10. The bristles 601 are distributed on the side of the second mounting portion 6212 away from the connecting portion 71 and contact the bottom wall 142 of the food container to achieve automatic cleaning of the bottom wall 142. As a specific installation example, the second mounting portion 6212 can be connected to the first mounting portion 6211 or to the support plate 721; this embodiment does not impose specific limitations on this.

[0049] In this embodiment, by setting the bristles 601 on the first mounting part 6211 and the second mounting part 6212 of the second cleaning brush 62, the side wall and bottom wall 142 of the food cavity 11 can be automatically cleaned at the same time, which improves the cleaning efficiency and cleaning effect of the food processing equipment 100.

[0050] Please refer to it again. Figure 3 In this embodiment, the food processing equipment 100 further includes a refrigeration mechanism 80, which is used to refrigerate the stirred ingredients in the container 10 to produce ice cream. The refrigeration mechanism 80 includes an evaporator coil 81, a compressor 82, and a condenser 83. The evaporator coil 81 is disposed outside the food chamber 11 and is used to contain a heat exchange medium, which can be a refrigerant such as water, Freon, or propane. The compressor 82 and the condenser 83 are both disposed in the housing 101 to reduce damage caused by contact with the food or liquid in the container 10. The compressor 82 is connected to the evaporator coil 81, and the condenser 83 is connected to the compressor 82. The heat exchange medium inside the evaporator coil 81 is outside the food cavity 11 and is used to absorb heat from the food cavity 11, changing from a liquid state to a gaseous state to cool the food in the food cavity 11. Then, the gaseous heat exchange medium is cooled back to a liquid state by the compressor 82 and the condenser 83. The liquid heat exchange medium returns to the evaporator coil 81 to continue absorbing heat and cooling. The above process is repeated continuously, which can achieve continuous cooling of the food in the food cavity 11 to freeze and shape the food to make the finished ice cream.

[0051] In some embodiments, the food processing apparatus 100 further includes a cooling fan 84 disposed in the housing space. The housing 101 has several heat dissipation holes communicating with the housing space. The suction end of the cooling fan 84 faces the condenser 83, and the blowing end of the cooling fan 84 faces the heat dissipation holes. Because of the cooling fan 84, the heat generated around the condenser 83 during operation can be drawn away by the cooling fan 84 and discharged from the housing 101 through the heat dissipation holes, thus preventing a large accumulation of heat around the condenser 83 and ensuring the safe and normal operation of the condenser 83.

[0052] In summary, this application provides a food processing device 100, which includes a container 10, a food processing blade 20, a first drive mechanism 30, a second drive mechanism 40, a transmission shaft 50, and a cleaning component 60. The cleaning component 60 is disposed within the food cavity 11 and detachably connected to the transmission shaft 50 driven by the second drive mechanism 40. This enables automatic cleaning of the container 10, improving cleaning efficiency. Furthermore, the detachable design of the cleaning component 60 facilitates cleaning and maintenance. The cleaning component 60 is further equipped with bristles 601. When the cleaning component 60 is installed within the food cavity 11, the bristles 601 contact the food processing blade 20. That is, the bristles 601 rotate under the drive of the second drive mechanism 40 and contact the food processing blade 20 to clean it. This eliminates the need for manual removal of the cleaning component 60, enhancing the device's intelligence and further improving cleaning efficiency. In this embodiment, the food processing blade 20 is also connected to the first drive mechanism 30 to achieve simultaneous rotation with the cleaning component 60, thereby increasing the relative contact with the cleaning component 60 and eliminating cleaning dead angles, which can more effectively remove food residues and stains on the food processing blade 20, and further improve the cleaning efficiency of the equipment.
