[0021] See also Figure 1 The embodiment of the present application provides a food processing device 100, which is used to process food. For example, it can have the functions of stirring and / or breaking the wall of food. The food processing device 100 can be a meat grinder, an ice cream machine, a smoothie machine, a cooking machine, etc., and this embodiment does not specifically limit this. For the convenience of description, in this embodiment, the food processing device 100 is described by taking an ice cream machine as an example.

[0022] See also Figures 2 to 3 In one embodiment provided in the present application, a food processing device 100 includes a storage barrel 10, a cover 20, a food processing knife 30, a first driving mechanism 40, a second driving mechanism 50, and a brush assembly 60. The storage barrel 10 is provided with a food cavity 11, and the cover 20 is connected to the storage barrel 10 and covers the food cavity 11. The food processing knife 30 is arranged in the food cavity 11, and the first driving mechanism 40 is connected to the food processing knife 30 to drive the food processing knife 30 to rotate. The second driving mechanism 50 is arranged outside the storage barrel 10, and the brush assembly 60 is detachably arranged in the food cavity 11. The brush assembly 60 includes a bracket 61 and bristles 62, the bracket 61 is transmission-connected to the second driving mechanism 50 so that the brush assembly 60 rotates under the drive of the second driving mechanism 50, and the bristles 62 are connected to the bracket 61. When the brush assembly 60 is installed in the food cavity 11, the bristles 62 contact the food processing knife 30.

[0023] When the food processing device 100 is cleaned, the user installs the brush assembly 60 in the food cavity 11. The brush assembly 60 can be specifically a structure arranged on the cover 20 and connected to the second driving mechanism 50. The brush assembly 60 can realize automatic cleaning of the holding barrel 10 under the drive of the second driving mechanism 50, thereby improving the cleaning efficiency. At the same time, the brush assembly 60 is detachably connected to the second driving mechanism 50, which is convenient for cleaning and maintenance of the brush assembly 60. Further, the brush assembly 60 includes a bracket 61 and bristles 62. When the brush assembly 60 is installed in the food cavity 11, the bristles 62 contact the food processing knife 30 to clean the food processing knife 30, and no manual removal is required to clean the food processing knife 30, thereby improving the intelligence of the device and further improving the cleaning efficiency. In the embodiment of the present application, the food processing knife 30 is also connected to the first driving mechanism 40 to realize simultaneous rotation with the brush assembly 60, thereby increasing the contact with the brush assembly 60, and can more effectively remove food residues and stains on the food processing knife 30, further improving the cleaning efficiency of the device.

[0024] Next, each component of the food processing device 100 and the specific structure of each component will be introduced one by one.

[0025] See also Figure 1 and Figure 2The housing 101 is used to install and protect the components. The housing 101 is also used to support the food processing device 100 at a place of use, such as the ground, a desktop or other supporting platforms. Specifically, the housing 101 is roughly in the shape of a rectangular parallelepiped. In other embodiments, the housing 101 can also be in any shape such as a cube, a cylinder or even an irregular shape. The housing 101 has a receiving space 102, and the receiving space 102 is used to install and place components. The components may include the above-mentioned receiving barrel 10, the food processing knife 30, the first drive mechanism 40, the second drive mechanism 50, the brush assembly 60, etc.

[0026] See also Figure 2 and Figure 3 The holding barrel 10 is a mechanism of the food processing device 100 for holding food to be processed. The holding barrel 10 is arranged in the housing 101 and is used to provide a low-temperature environment for the ice cream. The holding barrel 10 may specifically include an inner barrel (not shown in the figure) and an outer barrel (not shown in the figure). Both the inner barrel and the outer barrel are barrel-shaped structures. The inner barrel and the outer barrel constitute a double-layer barrel structure, which can effectively maintain the temperature required for food processing (such as a low-temperature environment). The inner barrel is usually made of food-grade metal to ensure food safety and hygiene. The outer barrel can be made of plastic or other materials to provide good thermal insulation. Among them, a thermal insulation material (not shown in the figure), such as polyurethane foam, can be filled between the inner barrel and the outer barrel to help with thermal insulation and reduce the impact of external heat on the internal temperature of the food processing device 100.

[0027] The containing barrel 10 has a food material cavity 11, and the food material cavity 11 is used to store the food materials needed for making ice cream, which may specifically be cream, butter, cheese, nuts, fruits, etc. It is understandable that when the food processing device 100 is used for other purposes, the food materials installed in the food material cavity 11 may also be grains, meat products, etc. When the containing barrel 10 is a fixed and non-detachable structure, the food material cavity 11 is specifically defined by the inner wall surface of the inner barrel; when the containing barrel is a detachable structure, it may include an inner liner 12 and an installation barrel, and the inner liner 12 is detachably arranged in the installation barrel to facilitate the taking and placing of food materials. At this time, the internal space of the inner liner 12 is used as the food material cavity 11. The inner liner 12 has an opening 121, and the food materials enter the food material cavity 11 from the opening 121 for food processing.

[0028] In this embodiment, food processing may be stirring or breaking the ice cream, and the food processing cutter 30 is disposed at the bottom of the food cavity 11. As an example, the food processing cutter 30 may be a wall breaking cutter, which is used to break larger or harder food in the food cavity 11 under the drive of the first drive mechanism 40. The food processing cutter 30 may be fixedly connected to the first drive mechanism 40 or may be detachably connected to the first drive mechanism 40, and this embodiment does not impose specific restrictions on this. As an example only, the food processing cutter 30 is detachably connected to the first drive mechanism 40 to facilitate the maintenance and management of the food processing cutter 30.

[0029] See also Figure 3 and Figure 4 , the food processing knife 30 may include a plurality of blades 31, and the first driving mechanism 40 may include a transmission shaft 401, and the transmission shaft 401 protrudes into the food cavity 11. The plurality of blades 31 are detachably connected to the transmission shaft 401 for easy replacement or cleaning. As an example, the transmission shaft 401 is simultaneously provided with the plurality of blades 31. As another example, the plurality of blades 31 are distributed at intervals along the axial direction of the transmission shaft 401, or the plurality of blades 31 may be integrally connected with the transmission shaft 401. In some embodiments, the spacings between the plurality of blades 31 and the bottom wall of the inner pot 12 are different, so that a certain stirring effect can be achieved and the food in different regions can be cut and crushed, thereby improving the cutting and crushing effect of the food processing knife 30 on the food. In other embodiments, the angles between the plurality of blades 31 and the transmission shaft 401 are different. Specifically, the angle between one of the blades 31 and the axis of the transmission shaft 401 is approximately 180°, that is, approximately parallel to the bottom wall of the inner pot 12. The angle between one of the blades 31 and the axis of the transmission shaft 401 is less than 90°, so that food in different areas can be cut and crushed. It should be noted that this embodiment does not specifically limit the number of blades 31 of the food processing knife 30. The number of blades 31 mentioned above can be two or more. In some embodiments, the food processing knife 30 can also include one blade 31, and different numbers of blades 31 can be installed according to actual needs.

[0030] In this embodiment, the first driving mechanism 40 is disposed inside the housing 101, and specifically can be installed below the accommodating barrel 10. The bottom wall of the accommodating barrel 10 is provided with an escape channel 13, which is connected to the food cavity 11 to accommodate part of the first driving mechanism 40, so that the first driving mechanism 40 at least partially protrudes into the food cavity 11 to connect to the food processing knife 30 and drive the food processing knife 30 to rotate.

[0031] Specifically, when the inner liner 12 is installed in the storage barrel 10, the bottom wall of the inner liner 12 includes a mounting platform 1201 and a main body 1202. The main body 1202 is roughly flat. The mounting platform 1201 protrudes from the main body 1202 to one side of the opening 121 of the inner liner 12, so as to prevent food or liquid from accumulating on the mounting platform 1201. The main body 1202 defines the plane of the bottom wall of the inner liner 12. The mounting platform 1201 is arranged in an annular shape and forms an avoidance channel 13. The avoidance channel 13 runs through the inner liner 12 and the storage barrel 10, so that the installation space between the storage barrel 10 and the inner liner 12 and the food cavity 11 are connected to each other. The first driving mechanism 40 includes a detachably connected driving member 41 and a transmission assembly 42. The transmission assembly 42 includes the transmission shaft 401 mentioned above. The driving member 41 can be used to drive the transmission assembly 42 to rotate. The transmission assembly 42 passes through the avoidance channel 13 and protrudes into the food cavity 11 to connect the food processing knife 30. The driving member 41 can be a driving motor, a rotary cylinder, etc. By providing a detachable transmission assembly 42 and a driving member 41, it is convenient to maintain and manage the first driving mechanism 40. At the same time, the transmission assembly 42 can avoid direct contact with the external environment in the mounting platform 1201, thereby reducing the influence of moisture on the transmission assembly 42 and extending the service life of the driving mechanism.

[0032] In order to prevent the food or liquid in the food cavity 11 from entering the avoidance channel 13 and affecting the normal operation of the first drive mechanism 40, the food processing device 100 also includes a seal 103, which is arranged in the avoidance channel 13 so that the transmission assembly 42 is sealed and connected to the avoidance channel 13. Specifically, the seal 103 is stacked and embedded in the surface of the mounting platform 1201, and is at least partially embedded in the avoidance channel 13 to seal the avoidance channel 13 together with the transmission assembly 42. The seal 103 is provided with a through hole, and the transmission shaft 401 is penetrated by the through hole and is detachably connected to the food processing knife 30. In some embodiments, in order to further improve the sealing effect, the radial size of the part of the structure of the seal 103 exposed outside the avoidance channel 13 can be larger than the radial size of the part of the structure located in the avoidance channel 13, so that it can cooperate with the mounting platform 1201 to form a good seal. The present embodiment does not limit the specific type and number of the seal 103. For example, the seal 103 may be a sealing sleeve or a sealing gasket, which may be made of a material having elasticity and waterproof properties, such as a rubber sealing sleeve. There may be multiple seals 103, and multiple seals 103 may be pressed against each other or multiple seals 103 may be arranged in the avoidance channel 13 and have an interference fit with the inner wall surface of the avoidance channel 13. The seal 103 may be completely sealed in the avoidance channel 13 or may at least partially seal the avoidance channel 13. Specifically, the seal 103 may be provided with multiple sealing parts, and the multiple sealing parts are used to contact different parts of the avoidance channel 13.

[0033] See also Figure 3and 5 Since the food processing device 100 needs to clean the food cavity 11 after processing, in order to achieve automatic cleaning of the food cavity 11 and the food processing knife 30, in this embodiment, the brush assembly 60 is arranged in the food cavity 11 and can rotate relative to the wall surface of the food cavity 11 and the food processing knife 30 under the drive of the second driving mechanism 50.

[0034] Specifically, the second driving mechanism 50 is arranged outside the inner container 12 / casing 101, and can be arranged on the cover 20. When the ice cream is prepared, the user installs the brush assembly 60 in the food cavity 11. The brush assembly 60 can be installed on the cover 20. One end of the brush assembly 60 is connected to the second driving mechanism 50, and the other end is extended to the bottom wall of the food cavity 11. The cover 20 is used to cover the opening 121 of the food cavity 11 and to install the second driving mechanism 50, which can prevent the food and liquid in the food cavity 11 from splashing during the food processing process and the cleaning process of the brush assembly 60. The second driving mechanism 50 can be a driving motor or a rotating cylinder or other driving member 41, and this embodiment does not make specific restrictions on this. The brush assembly 60 includes a bracket 61 and bristles 62. The bracket 61 is a supporting structure of the brush assembly 60, which is used to fix and support the bristles 62 and is transmission-connected to the second driving mechanism 50 to drive the bristles 62 to rotate. The bristles 62 are used to contact the inner wall surface of the food cavity 11 and the food processing knife 30 , and automatically clean the food processing device 100 under the drive of the bracket 61 .

[0035] In the present embodiment, the brush assembly 60 may further include a rotating shaft 601, which is arranged in the shape of a long rod and is detachably connected to the second driving mechanism 50, which may be a snap connection, a plug connection, or a magnetic connection, and the present embodiment does not impose any specific restrictions on this. The number of brackets 61 may be multiple or one, and for ease of explanation, in the present embodiment, the number of brackets 61 is one. In some embodiments, the number of brackets 61 is multiple, and the multiple brackets 61 are all connected to the rotating shaft 601 and surround the outer circumference of the rotating shaft 601 to increase the distribution area of ​​the bristles 62 relative to the inner wall of the food cavity 11, thereby improving the cleaning effect. The multiple brackets 61 may be arranged in sequence along the axial direction of the rotating shaft 601 or may be connected to the same position of the rotating shaft 601, and the present embodiment does not impose any specific restrictions on this. It should be noted that any number of brackets 61 are applicable to any embodiment of the present application.

[0036] In this embodiment, the bracket 61 includes a connecting portion 611 and a brush plate 612. The connecting portion 611 serves as a connecting structure of the bracket 61. It is connected between the rotating shaft 601 and the brush plate 612, and can rotate with the rotating shaft 601 as the rotation center under the drive of the rotating shaft 601 and the second driving mechanism 50. The axial direction of the rotating shaft 601 can be parallel to or coincide with the rotation axis direction of the food processing knife 30, so as to ensure that the brush assembly 60 can fully clean the food cavity 11 and the food processing knife 30, thereby achieving effective cleaning. The connecting portion 611 extends along the radial direction of the rotating shaft 601, for example, extends toward the inner wall surface of the food cavity 11, and is spaced from the inner wall surface of the food cavity 11. The brush plate 612 is arranged at one end of the connecting portion 611 away from the rotating shaft 601 to facilitate the cleaning of the inner wall surface of the food cavity 11. In this embodiment, there are multiple connecting parts 611, which are arranged at intervals on the outer periphery of the rotating shaft 601 and are respectively connected between the rotating shaft 601 and the bristle plate 612. As a specific example, there are six connecting parts 611 to achieve a stable connection between the bristle plate 612 and the rotating shaft 601. It should be noted that the number of connecting parts 611 can be one or more, and the stability of the brush assembly 60 is improved by setting a plurality of connecting parts 611. This embodiment does not limit the specific number of connecting parts 611, the relative position of each connecting part 611 and the rotating shaft 601, and different numbers of connecting parts 611 and connecting parts 611 distributed in different directions along the rotating shaft 601 can be set according to actual use requirements.

[0037] The bristle plate 612 is a structure of the brush assembly 60 for contacting the cleaning part. The bristle plate 612 is generally plate-shaped. The bristles 62 are densely planted on the side of the bristle plate 612 facing the wall of the inner pot 12 and the side facing the food processing knife 30. The bristles 62 are used to rotate with the bristle plate 612 and the rotating shaft 601, and scrape or absorb the food attached to the inner wall of the inner pot 12 during the rotation process. The bristles 62 are arranged around the outer periphery of the rotating shaft 601. The bristles 62 can be distributed in multiple rows along the axial direction of the bristle plate 612 to increase the distribution area of ​​the bristles 62. Adjacent bristles 62 are staggered to increase the contact area between the bristles 62 and the inner wall of the food cavity 11 and avoid missing the cleaning area, so as to clean more effectively and ensure the cleaning effect.

[0038] It should be noted that the number of bristle plates 612 can be one or more, and this embodiment does not impose specific restrictions on this. For example, when the number of bristle plates 612 is one, one bristle plate 612 is connected to the connecting portion 611 and rotates with the rotating shaft 601, and can be specifically rotated clockwise or counterclockwise relative to the rotating shaft 601, and the rotation angle is not specifically limited. In this embodiment, the number of bristle plates 612 is two, and the two bristle plates 612 are arranged at intervals and are respectively located on both sides of the rotating shaft 601, and each bristle plate 612 is connected to the rotating shaft 601 through the connecting portion 611. It can be understood that in some other embodiments, the bristle plates 612 can also be three, four, five or other numbers, and different numbers of bristle plates 612 can be set according to actual use requirements to improve cleaning efficiency.

[0039] The above-mentioned inner wall surface can be understood as the side wall and bottom wall of the inner pot 12, and the bristles 62 are distributed on at least one side of the bristle plate 612 facing the side wall and the bottom wall of the food cavity 11. Specifically, in the present embodiment, the bristle plate 612 includes a first mounting portion 6121 and a second mounting portion 6122. The first mounting portion 6121 is located on the side of the brush assembly 60 close to the side wall of the food cavity 11 to clean the side wall, and the first mounting portion 6121 is extended along the axial direction of the rotating shaft 601. Specifically, when the brush assembly 60 is located in the food cavity 11, the first mounting portion 6121 can specifically extend to the bottom of the food cavity 11, and the bristles 62 are distributed on the side of the first mounting portion 6121 facing the side wall and in contact with the side wall. Furthermore, the second mounting portion 6122 is connected to one end of the first mounting portion 6121 close to the bottom wall, and is extended along the radial direction of the rotating shaft 601. When the brush assembly 60 is located in the food cavity 11, the second mounting portion 6122 is located at the bottom of the food cavity 11 and is arranged parallel to the bottom wall of the inner pot 12. The bristles 62 are distributed on the side of the second mounting portion 6122 away from the rotating shaft 601, and contact the bottom wall of the inner pot 12 to achieve automatic cleaning of the bottom wall. As a specific installation example, the second mounting portion 6122 can be connected to the first mounting portion 6121, the rotating shaft 601, or the connecting portion 611, and this embodiment does not specifically limit this.

[0040] By arranging the bristles 62 on the first mounting portion 6121 and the second mounting portion 6122 , the side wall and the bottom wall of the food cavity 11 can be automatically cleaned at the same time, thereby improving the cleaning efficiency and cleaning effect of the food processing device 100 .

[0041] Furthermore, in this embodiment, in order to further improve the user experience and the cleaning effect of the food processing device 100, the bristles 62 can also extend toward the food processing knife 30 and contact the food processing knife 30 to achieve automatic cleaning of the food processing knife 30.

[0042] Specifically, the second mounting portion 6122 is provided with bristles 62 on the side away from the bottom wall, and the bristles 62 extend in the direction of the rotating shaft 601. That is, when the brush assembly 60 is installed in the food cavity 11, the bristles 62 arranged on the second mounting portion 6122 away from the bottom wall of the storage barrel 10 extend toward the blade 31 and contact the blade 31, so that when the brush assembly 60 rotates under the drive of the second driving mechanism 50, the bristles 62 can automatically clean the food processing knife 30. As a specific installation example, the blade 31 and the bottom wall of the food cavity 11 are spaced and form an avoidance space 104, and the bristles 62 located on the side of the second mounting portion 6122 away from the bottom wall extend into the avoidance space 104 and contact the blade 31. By providing the above-mentioned bristles 62 that protrude into the avoidance space 104 and contact the blade 31, the blade 31 can be cleaned without manually removing the blade 31, and the food processing knife 30 can be automatically cleaned, thereby improving the user experience and the intelligence of the food processing equipment 100, and further improving the cleaning efficiency and cleaning effect. It should be noted that when the bristles 62 automatically clean the food processing knife 30, the blade 31 can be in a stationary state or in a rotating state. As an example, when the bristles 62 clean the food processing knife 30, the blade 31 rotates under the drive of the second drive mechanism 50, thereby increasing the contact with the brush assembly 60, and can more effectively remove food residues and stains on the food processing knife 30, further improving the cleaning efficiency of the equipment.

[0043] See also Figure 6 In some embodiments, in order to improve the intelligence of the food processing device 100, the food processing knife 30 can also be used as a stirring device to stir the food in the food cavity 11. The stirring device can be a stirring structure commonly used in the art, and this embodiment will not be described in detail. However, in this embodiment, in order to take into account both the stirring function and the wall breaking function, the food processing device 100 can also include a stirring knife 70 that is replaced and installed with the brush assembly 60. The stirring knife 70 is detachably connected to the second drive mechanism 50 and is spaced and coaxially arranged with the food processing knife 30. At this time, the food processing knife 30 is used as a wall breaking knife. By providing the above-mentioned stirring knife 70, the stirring knife 70 and the brush assembly 60 are allowed to share the second drive mechanism 50. On the one hand, more functional components can be accommodated in a limited space, which improves the convenience of use of the food processing device 100, optimizes the space utilization of the device, and makes the device more compact; on the other hand, it can reduce production costs and improve the user experience.

[0044] The present embodiment does not limit the specific structure of the stirring tool 70, and is only used as an installation example. When the food processing device 100 performs stirring or / and wall breaking, the brush assembly 60 is removed from the second drive structure, and one end of the stirring tool 70 is connected to the second drive mechanism 50, and the other end extends from the cover 20 to the bottom of the food cavity 11 to facilitate stirring all the food in the food cavity 11. The stirring tool 70 may include a stirring shaft 701 and a plurality of stirring members 702 connected to the stirring shaft 701. The spacing between adjacent stirring members 702 and the bottom of the food cavity 11 may be different, so that food in different areas can be stirred and mixed to improve the stirring effect of the food.

[0045] In this embodiment, the brush assembly 60 or the stirring tool 70 can be detachably connected to the second drive mechanism 50 through a mounting joint (not shown in the figure). Specifically, a mounting hole (not shown in the figure) for mounting the second drive mechanism 50 is provided on the cover body 20, and the mounting hole is connected to the food cavity 11. The second drive mechanism 50 is provided with a mounting joint (not shown in the figure). When the second drive mechanism 50 is arranged in the mounting hole, the mounting joint is located on the side of the second drive mechanism 50 facing the food cavity 11. The brush assembly 60 has a first connecting joint (not shown in the figure) corresponding to the mounting joint, and the first connecting joint can be specifically arranged at one end of the rotating shaft 601 facing the cover body 20 to facilitate connection with the mounting joint. The stirring tool 70 has a second connecting joint (not shown in the figure) corresponding to the mounting joint, and the second connecting joint is specifically arranged at one end of the stirring rotating shaft 701 facing the cover body 20 to facilitate connection with the mounting joint. It should be noted that since the second connecting joint and the first connecting joint can be detachably connected to the mounting joint, in order to improve the installation efficiency, the second connecting joint and the first connecting joint have the same configuration. For example, when the first connection joint or the second connection joint is connected to the installation joint by plugging, the first connection joint and the second connection joint are of the same structure and can be either a protrusion structure or a groove structure, and the installation joint is the other. When the first connection joint or the second connection joint is connected to the installation joint by rotation, the first connection joint and the second connection joint are of the same structure and can be either a connecting shaft or an axial hole, and the installation joint is the other. It can be understood that the first connection joint / the second connection joint and the installation joint can also be connected by other means, such as magnetic connection, etc., and this embodiment does not specifically limit this.

[0046] See also Figure 6In this embodiment, the food processing device 100 further includes a heating element 105, which is disposed on the outside of the food cavity 11, and can be specifically disposed on the bottom wall of the containing barrel 10. The heating element 105 is a device used by the food processing device 100 to heat the containing barrel 10. Specifically, the heating element 105 can be used to heat the inner barrel so that part of the food (such as butter, cheese, etc.) in the food cavity 11 can be quickly melted and fully mixed, thereby stimulating the aroma of the food, improving the taste of the finished ice cream, or heating during the cleaning process of the brush assembly 60 so that the oil and dirt in the food cavity 11 are quickly dissolved to improve the cleaning efficiency and cleaning effect. The heating element 105 can specifically be an electric heating tube or other heating elements, such as a positive temperature coefficient thermistor (PTC) heating element, a ceramic heating device, etc., and this embodiment does not impose specific restrictions on this.

[0047] In this embodiment, the food processing device 100 also includes a refrigeration mechanism (not shown in the figure), which is used to refrigerate the stirred ingredients in the inner tank 12 to make finished ice cream. The refrigeration mechanism includes an evaporating coil 81, a compressor 82 and a condenser 83; the evaporating coil 81 is arranged outside the inner tank 12, and the evaporating coil 81 is used to accommodate a heat exchange medium, which can be a refrigerant such as water, Freon, propane, etc. The compressor 82 and the condenser 83 are both arranged in the accommodating space 102 to reduce damage caused by contact with the ingredients or liquid in the inner tank 12. The compressor 82 is connected to the evaporating coil 81, and the condenser 83 is connected to the compressor 82. The heat exchange medium in the evaporating coil 81 absorbs the heat of the food in the inner tank 12 outside the inner tank 12 and changes from liquid to gas to cool the food in the inner tank 12. Then the gaseous heat exchange medium is cooled by the compressor 82 and the condenser 83 and turns back into a liquid heat exchange medium. The liquid heat exchange medium returns to the evaporating coil 81 to continue absorbing heat and cooling. The above process is repeated continuously to achieve continuous cooling of the food in the inner tank 12, so that the food is frozen and shaped to make a finished ice cream.

[0048] In some embodiments, the food processing device 100 further includes a cooling fan 84, which is disposed in the accommodation space 102. The housing 101 is provided with a plurality of cooling holes connected to the accommodation space 102. The air suction end of the cooling fan 84 faces the condenser 83, and the air blowing end of the cooling fan 84 faces the cooling holes. Due to the provision of the cooling fan 84, the heat generated around the condenser 83 when it is working can be sucked away by the cooling fan 84 and discharged from the housing 101 through the cooling holes, so as to avoid a large amount of heat accumulation around the condenser 83, thereby ensuring that the condenser 83 can work safely and normally.

[0049] In summary, the embodiment of the present application provides a food processing device 100. The embodiment of the present application provides a food processing device 100, which includes a storage bucket 10, a cover body 20, a food processing knife 30, a first drive mechanism 40, a second drive mechanism 50 and a brush assembly 60. The brush assembly 60 is arranged in the food cavity 11 of the storage bucket 10 and is connected to the second drive mechanism 50, which can realize automatic cleaning of the storage bucket 10 and improve the cleaning efficiency. At the same time, the brush assembly 60 is detachably connected to the second drive mechanism 50, which is convenient for cleaning and maintenance of the brush assembly 60. Further, the brush assembly 60 includes a bracket 61 and bristles 62. When the brush assembly 60 is installed in the food cavity 11, the bristles 62 contact the food processing knife 30 to clean the food processing knife 30. There is no need to manually remove the food processing knife 30 to clean the food processing knife 30, which improves the intelligence of the equipment and further improves the cleaning efficiency. In an embodiment of the present application, the food processing knife 30 is also connected to the first drive mechanism 40 to achieve simultaneous rotation with the brush assembly 60, thereby increasing the contact with the brush assembly 60, being able to more effectively remove food residues and stains on the food processing knife 30, and further improving the cleaning efficiency of the equipment.

[0050] See also Figure 7 The embodiment of the present application also provides a control method of a food processing device 100, which is used to be applied to the food processing device 100 provided in any of the above embodiments. The control method includes responding to a work start instruction, controlling the second drive mechanism 50 to drive the brush assembly 60 to rotate according to a preset first working cycle; wherein, in a first working cycle, the brush assembly 60 rotates clockwise for a first working time and then counterclockwise for a second working time; responding to a work end instruction, controlling the second drive mechanism 50 to stop running.

[0051] By setting the above control method, the brush assembly 60 can rotate bidirectionally according to the predetermined first working cycle, which can more effectively remove dirt and dust in different directions and realize automatic cleaning of the food processing device. At the same time, it can reduce the manual intervention of the user in the cleaning process, improve the user's experience, and provide the user with convenience in the food processing process.

[0052] The following introduces the application environment of the control method provided in the embodiment of the present application.

[0053] The food processing device 100 includes the container 10, the cover 20, the food processing knife 30, the first drive mechanism 40, the second drive mechanism 50, the brush assembly 60, and the heating element 105 mentioned in any of the above embodiments. In order to save space, the embodiments of this application will not be described in detail, and please refer to the above embodiments for details.

[0054] In this embodiment, the food processing device 100 includes a controller 90 and a timing device 91, and the controller 91 is electrically connected to the timing device 90 to control the operation of the timing device 91. Specifically, the controller 90 is used to control the start or stop of the timing device 91, as well as the working parameters when it is started. In some embodiments, the housing 101 may also be provided with a control panel 1011, and the controller 90 is electrically connected to the control panel 1011. When the control panel 1011 receives an operation signal for any functional device, it generates a corresponding electrical signal and sends it to the controller 90, and the controller 90 controls the food processing device 100 based on the electrical signal. In this embodiment, after receiving the work start instruction, the controller 90 starts to control the second drive mechanism 50 to drive the brush assembly 60 to rotate according to the preset first working cycle. The controller 90 can be a microcontroller unit (MCU), a microprocessor (MPU), a central processing unit (CPU), etc., and this embodiment does not limit this.

[0055] The timing device 91 is used to record the first working time and the second working time of the brush assembly 60 in the first working cycle. The number of the timing devices 91 can be one or more, and the present embodiment does not impose any specific restrictions on this. The timing device 91 is arranged in the housing 101, and can be specifically arranged on the containing barrel 10. As an example, the number of the timing device 91 is one, and the controller 90 controls the food processing equipment 100 to start timing while responding to the work start instruction. After the controller 90 obtains that the time recorded by the timing device 91 meets the first working time, the timing device 91 is controlled to record the second working time.

[0056] In some embodiments, the food processing device 100 may further include a mobile device (not shown) connected to the controller 90 to receive control data sent by the mobile device. For example, the user operates the mobile device to implement the corresponding operation of the food processing device 100. For example, the user inputs the first working time, the second working time and other operations through the mobile device. The mobile device can encapsulate the corresponding operation data into control data and transmit it to the processing structure. The processing structure then controls the food processing device 100 to work according to the control data, so as to implement the mobile device to control the food processing device 100.

[0057] In some embodiments, the food processing device 100 further includes a temperature sensor 92, which is used to detect the temperature in the holding barrel 10, that is, the temperature in the food cavity 11. The present embodiment does not limit the specific type of the temperature sensor 92. The number of temperature sensors 92 can be one or more, and they can be set at any position in the food cavity 11. As just an installation example, the number of temperature sensors is one, which is installed near the opening in the food cavity 11. It is understandable that the temperature sensor 92 can also be installed on the side wall of the food cavity 11 and near the heating element 105. The temperature data collected by the temperature sensor 92 in real time is the temperature in the holding barrel 10. When the number of temperature sensors 92 is more than one, the multiple temperature sensors 92 use the average value of the temperature data collected at the same time as the temperature in the holding barrel 11.

[0058] In some embodiments, the food processing device 100 further includes a detection component 93. The detection component 93 is used to detect whether the food processing device 100 meets the conditions for automatic cleaning to ensure the efficiency and stability of the cleaning process. The detection component 93 may include a sensor 931 and a sensor 932 electrically connected to each other, and the number of the sensor 931 and the sensor 932 may be multiple, and the multiple sensors 931 and the multiple sensors 932 are arranged one-to-one. Any one of the sensors 931 and the sensors 932 arranged one-to-one can be arranged at the bottom of the cover 20, the first drive mechanism 40, the second drive mechanism 50 and the containing bucket 10. As a specific example, the detection component 90 includes a first sensor 9311 and a first sensor 9321, and the detection component 90 is used to detect whether the cover 20 is correctly installed in the containing bucket 10. Specifically, the cover 20 has a preset installation position. When the cover 20 is installed at the preset installation position, the first induction signal value formed by the first induction body 9312 received by the first sensor 9311 is maximum or the first induction signal value falls within the predetermined first induction signal value range, and the controller 90 controls the food processing device 100 to respond to the work start instruction. The above "the first induction signal value is maximum or the first induction signal value falls within the predetermined first induction signal value range" indicates that the cover 20 is correctly installed in the containing bucket 10.

[0059] The first sensor 9311 may be a Hall sensor, the first induction body 9321 may be a magnet, the magnet may be arranged on the cover 20, and the Hall sensor may be arranged on the side wall of the container 10 and located at one end close to the cover 20. When the cover 20 is installed to the preset installation position, it can face the Hall sensor. The Hall sensor is used to detect the magnet and generate a first induction signal. The first induction signal value represents the magnetic field strength value of the magnet received by the Hall sensor. When the first induction signal value is maximum or the first induction signal value falls within a predetermined magnetic field strength range, the controller controls the food processing device to respond to the start work instruction. It is understandable that the magnet may also be arranged on the side wall of the container 10, and the Hall sensor may also be arranged on the cover 20.

[0060] The first sensor 9311 may also be an infrared transmitter, and the first sensor 9321 may be an infrared receiver. The infrared transmitter may be arranged on the cover 20, and the infrared receiver may be arranged on the side wall of the storage bucket 10 and located at one end close to the cover 20. When the cover 20 is installed to the preset installation position, the infrared transmitter can face the infrared receiver, and the infrared receiver is used to detect the infrared light formed by the infrared transmitter and generate a first sensing signal. At this time, the first sensing signal represents the radiation intensity value of the infrared light. When the first sensing signal value is maximum or the first sensing signal value falls within the predetermined infrared light radiation intensity range, the controller controls the food processing device 100 to respond to the start work instruction. Similarly, the infrared transmitter may also be arranged on the side wall of the storage bucket 10, and the infrared receiver may also be arranged on the cover 20.

[0061] In other embodiments, the detection component 93 may include a second sensor (not shown in the figure) and a second sensor (not shown in the figure), and the second sensor and the second sensor are used to detect whether the second drive mechanism 50 and the brush assembly 60 are installed correctly. Any one of the second sensor and the second sensor is arranged at one end of the second drive mechanism 50 facing the brush assembly 60, and the other is arranged at one end of the brush assembly 60 facing the second drive mechanism 50. The second sensor and the second sensor can be the Hall sensor, magnet, infrared transmitter and infrared receiver mentioned above. For details, please refer to the above embodiment. In order to save space, the embodiment of this application is not described in detail. When the second sensing signal value received by the second sensor is the maximum or the second sensing signal value falls within the predetermined second sensing signal value range, the controller 90 controls the food processing equipment 100 to respond to the start work instruction. The second sensing signal value is the radiation intensity value or magnetic field intensity value of the infrared light mentioned above.

[0062] In other embodiments, the detection component 93 may also include a pressure sensor, which is used to detect the weight change of the amount of water added to the holding barrel during the food processing process, so as to confirm whether the amount of water meets the conditions for the food processing device 100 to perform automatic cleaning. In this embodiment, the pressure sensor is arranged at the bottom of the holding barrel 10 to detect the weight of the amount of water added to the food cavity 11. Specifically, the number of pressure sensors can be one or more. When the number of pressure sensors is one, the pressure sensor is arranged at the center of the bottom of the bottom wall of the holding barrel 10. At this time, the value detected by the pressure sensor is the weight of the amount of water added to the food cavity 11. When the number of pressure sensors is multiple, multiple pressure sensors are arranged in sequence on the bottom wall of the holding barrel 10, and the average value of the values ​​detected by multiple pressure sensors at the same time is the total weight of the amount of water added to the food cavity 11. The pressure sensor specifically detects weight, and the weight represents the weight of the liquid added to the holding barrel during cleaning.

[0063] In other embodiments, the detection component 93 may also include a liquid level sensor 933, which is used to detect the water level in the holding barrel 10, so as to confirm whether the water volume meets the conditions for automatic cleaning of the food processing equipment 100. Specifically, the liquid level sensor 933 is arranged on the inner wall surface of the inner tank, and it can determine the water level information by obtaining the signal value returned from the liquid surface or the buoyancy magnitude of the sensor. For example, the liquid level sensor 933 can be an ultrasonic liquid level sensor, which transmits ultrasonic pulses to the liquid surface and receives the reflected sound waves. By calculating the time of the sound wave going back and forth, the water level information is obtained, so as to judge whether the water volume meets the conditions for automatic cleaning of the food processing equipment 100. Of course, the liquid level sensor 933 can also be other forms of sensors, such as a float type liquid level sensor, a capacitive liquid level sensor, etc., and this embodiment does not specifically limit this.

[0064] In the embodiments of the present application, Figure 8 The control method provided in the embodiment of the present application is described by taking the processing device as an example. It can be understood that, except Figure 7 The food processing equipment shown may also be food processing equipment of other structural forms, and the present application does not impose any limitation on this.

[0065] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0066] Please refer to Figure 8 , which shows a flow chart of a control method of a food processing device provided by an embodiment of the present application. The control method can be applied to automatic cleaning before food processing and also to automatic cleaning after food processing, and the control method includes the following steps S210 to S220.

[0067] S210. In response to a work start instruction, control the second driving mechanism to drive the brush assembly to rotate according to a preset first working cycle, wherein in one of the first working cycles, the brush assembly rotates clockwise for a first working time and then rotates counterclockwise for a second working time.

[0068] In some embodiments, the work start instruction is triggered by the user to instruct the food processing device to start this working process, which can be specifically to control the second drive mechanism to rotate to drive the brush assembly to rotate. For example, when the user needs the food processing device to perform automatic cleaning, the user can select the start control through the control panel or a mobile device connected to the cooking appliance to instruct the food processing device to start this automatic cleaning process. After the food processing device obtains the operation signal for the start control, in response to the operation signal, the food processing device controls the operation of the food processing device to control the second drive mechanism to install a preset first working cycle to drive the brush assembly to rotate. The above-mentioned operation signal can be a single-click operation signal, a double-click operation signal, a sliding operation signal, etc.; when the start control is a physical control, the above-mentioned operation signal can be a single or multiple press operation signals.

[0069] In other embodiments, the food processing device responds to a pre-stored work start instruction when the scheduled time arrives. The scheduled time is the time preset by the user for the expected food processing device to start automatic cleaning, and these food processing devices can be generated and stored in the processor according to the user's preset settings. Optionally, the control panel on the food processing device also includes a reservation control. When the food processing device receives an operation signal for the reservation control and the reservation duration input by the user, the food processing device responds to the work start instruction when the scheduled time arrives. For example, the reservation duration input by the user is three minutes, and the food processing device automatically cleans up three minutes after completing food processing. The time between the moment when the food processing device obtains the reservation duration and the reservation time is the above-mentioned reservation duration.

[0070] In this embodiment, the food processing device automatically responds to the work start instruction after the brush assembly is installed. Specifically, after the user installs the brush assembly on the second drive mechanism, the controller obtains the relative position information of the brush assembly and the second drive mechanism, and controls the food processing device to respond to the work start instruction when the relative position information satisfies that the brush assembly and the second drive mechanism are installed and connected and the second drive mechanism is connected to the cover body.

[0071] It should be noted that the food processing equipment may include a second driving mechanism and a brush assembly. In a first working cycle, the second driving mechanism is controlled to drive the brush assembly to rotate with a certain output power, and the rotation rate of the brush assembly is positively correlated with the output power of the second driving mechanism.

[0072] The first working cycle represents the operation cycle of the brush assembly completing one cycle of rotation, specifically including the brush assembly rotating clockwise for a first working time and then rotating counterclockwise for a second working time. The first working cycle ends when the brush assembly completes the entire sequence of clockwise and counterclockwise rotations. During the cleaning process, multiple first working cycles can be executed cyclically until the food processing device ends automatic cleaning.

[0073] In this embodiment, when the food processing device is in the first working cycle, the timing device records the first working time and the second working time in real time. The timing device can be built into the controller or processor of the food processing device. When receiving the signal of the food processing device in response to the work start instruction, the controller controls the timing device to start timing, and the brush assembly rotates clockwise; when the time recorded by the timing device meets the first working time, the timing stops and re-records, at which time the brush assembly starts to rotate clockwise and then turns counterclockwise; when the time recorded by the timing device meets the second working time, the brush assembly stops rotating or turns again.

[0074] The first working time and the second working time may be parameters that are pre-fixed in the processor or memory of the food processing device. As an example only, the value range of the first working time may be 3min-5min (including the endpoints), for example, the first working time may be 3min, 4min, 5min, etc. The value range of the second working time may be 4min-6min (including the endpoints), for example, the second working time may be 4min, 5min, 6min, etc. This embodiment does not impose specific restrictions on this.

[0075] In other embodiments, the values ​​of the first working time and the second working time may also be the first working time and the second working time set by the user through a control panel or a mobile device connected to the food processing equipment before cleaning begins. At this time, the specific time can be set according to the user's cleaning needs, thereby improving the cleaning effect and cleaning efficiency. This embodiment does not limit the specific parameter values ​​of the first working time and the second working time.

[0076] S220: In response to a work end instruction, control the second driving mechanism to stop running.

[0077] In this embodiment, the work end instruction indicates that the cleaning is over and the power supply of the second drive mechanism is cut off. Specifically, the second drive mechanism stops running, the timing device stops timing, and the brush assembly stops rotating. At this time, the user can pour out the sewage in the food cavity. As an example, the work end instruction can be specifically triggered by the user through the control panel on the housing or a mobile device connected to the control panel to instruct the food processing device to end the automatic cleaning process. As another example, the work end instruction can also be automatically triggered by the food processing device when the scheduled time arrives. For example, after the running time of the first working cycle recorded by the timing device meets 10 minutes, the food processing device automatically responds to the work end instruction. In some embodiments, it is also possible to detect dirt by setting a sensing device. The sensing device can be specifically set on the wall-breaking knife, the side wall and the bottom wall of the inner pot. When the detected signal value meets the preset value, the controller controls the food processing device to automatically respond to the work end instruction. For example, the sensing device can be an infrared sensor, and the oily substance can absorb infrared light energy of a specific wavelength, so as to determine whether the oily substance is cleaned by detecting the energy of the reflected light.

[0078] In summary, in the control method of the food processing device provided in the embodiment of the present application, bidirectional rotation can more effectively remove dirt and dust in different directions and realize automatic cleaning of the food processing device. At the same time, it can reduce the manual intervention of the user in the cleaning process, improve the user's experience, and provide the user with convenience in the food processing process.

[0079] In some embodiments, in order to accelerate the dissolution of oil stains in the food cavity and improve the cleaning efficiency and cleaning effect, the food processing equipment also includes a heating element and a temperature sensor. For details, please refer to the heating element and temperature sensor mentioned above. In this embodiment, the number of heating elements is one, and one heating element is arranged at the bottom of the receiving bucket and heats the receiving bucket at a first power. Before responding to the work start instruction and controlling the second drive mechanism to drive the brush assembly to rotate according to a preset first working cycle, the control method may also include: the controller controls the heating element to operate at a first power, and after the temperature of the receiving bucket rises to a temperature greater than or equal to a preset temperature, controls the heating element to operate at a second power to keep the temperature in the receiving bucket within a preset range.

[0080] The first power may be a parameter that is pre-fixed in the processor or memory before the food processing device leaves the factory, or may be a parameter that the user sets through a control panel or a mobile device connected to the food processing device. This embodiment does not impose any specific restrictions on this. The temperature sensor is used to detect the temperature inside the food cavity. After the heating element heats the holding barrel, the temperature sensor detects the temperature inside the food cavity in real time. Specifically, one or more temperature sensors may be provided, and the temperature sensor may be provided at various locations in the food cavity. In this embodiment, the number of temperature sensors is one, which is provided on the side wall of the food cavity.

[0081] In some embodiments, the heating element heats the holding barrel at a first power. When the temperature of the holding barrel rises to a preset temperature, the food processing device enters a heat preservation stage to prevent the oil from condensing. At this time, the heating element operates at a second power, and the second power is less than the first power. The preset temperature may be a parameter fixed in a processor or memory of the food processing device. For example, the preset temperature may range from 65°C to 85°C (including endpoints), for example, the preset temperature may be 65°C, 70°C, 75°C, 80°C, 85°C, etc. As another example, the preset temperature may also be manually adjusted according to the type of food to be cleaned. For example, the preset temperature may also be a preset temperature set by the user through a control panel or a mobile device connected to the food processing device before the cleaning begins. At this time, the preset temperature range may be adjusted according to the user's cleaning needs. This embodiment does not specifically limit the range of the preset temperature. Similarly, the setting method of the preset range may also refer to the preset temperature mentioned above. In order to save space, this embodiment does not specifically limit this. As just an example, the preset temperature range may be in the range of 45°C-60°C (including the endpoints), for example, the preset temperature range may be 45°C, 60°C, 55°C, 60°C, etc.

[0082] It should be noted that the second power is less than the first power, and the actual temperature can be maintained within the preset temperature range. For example, when the food processing equipment includes a heating element, the heating element works at a larger first power to accelerate the dissolution of the oily substance to save cleaning time. When the temperature in the holding barrel rises to a temperature greater than or equal to the preset temperature, the heating element uses a smaller second power for heating, which can prevent the oily substance from condensing, while providing a heating environment to improve the cleaning efficiency and cleaning effect. In some embodiments, the number of heating elements can also be multiple, and the total output power of multiple heating elements is the first power. The purpose of reducing the heating power can be achieved by stopping some heating elements from working. At this time, the total output power of the heating elements that are still working is the second power. As a specific example, the value of the first power can be 1500W, and the value of the second power can be 200W. This embodiment does not impose specific restrictions on this.

[0083] In this embodiment, when the temperature in the containing barrel rises to fall within the preset temperature range, a step (i.e., step S210) is executed in response to a work start instruction to control the second drive mechanism to drive the brush assembly to rotate according to a preset first working cycle. For specific instructions on "execution in response to a work start instruction, control the second drive mechanism to drive the brush assembly to rotate according to a preset first working cycle", please refer to S210. In order to save space, this embodiment does not provide a specific description of this. It should be noted that this embodiment does not impose specific restrictions on the number of cycles in which the controller controls the brush assembly to rotate in the first working cycle. Specifically, it can be one cycle or multiple cycles. The number of cycles can be a parameter value pre-fixed in the controller or processor before the food processing equipment leaves the factory, or it can be a parameter value set by the user through the control panel and the mobile terminal connected to the controller.

[0084] By providing the above-mentioned heating element and temperature sensor, a heating environment can be formed, thereby improving the processing efficiency and processing effect.

[0085] In some embodiments, in order to further improve the automatic cleaning effect of the food processing equipment, the control method also includes controlling the first drive mechanism to drive the food processing knife to rotate according to a preset second working cycle during the operation of the second drive mechanism, wherein in a second working cycle, the food processing knife rotates for a third working time and then remains stationary for a fourth working time.

[0086] The second working cycle and the first working cycle can be carried out synchronously, that is, the food processing device responds to the specified working instruction, and the controller can control the second drive mechanism and the first drive mechanism to operate simultaneously, that is, the brush assembly and the food processing knife rotate at the same time. In other embodiments, there may be an interval between the second working cycle and the first working cycle. For example, after the second drive mechanism drives the brush assembly to rotate in the first working cycle for one minute, the first drive mechanism drives the food processing knife to rotate in the first working cycle. It is understandable that there may be other intervals between the second working cycle and the first working cycle, and this embodiment does not impose specific restrictions on this.

[0087] The second working cycle represents the operation cycle of the food processing knife completing a cycle of rotation. The second working cycle may specifically include the entire sequence of the food processing knife completing the rotation for the third working time and then remaining stationary for the fourth working time. The third working time represents the time required for the food processing knife to rotate from the beginning to stop rotating in response to the working instruction. The fourth working time represents the time required for the food processing knife to start the next rotation from stopping rotating. It should be noted that the food processing knife may rotate clockwise in a second working cycle. For example, the food processing knife rotates clockwise for the third working time and then remains stationary for the fourth working time. The food processing knife may also rotate counterclockwise in a second working cycle. For example, the food processing knife rotates clockwise for the third working time and then remains stationary for the fourth working time. In some other embodiments, the food processing knife may also rotate clockwise for the third working time and then remain stationary for the fourth working time in a second working cycle, and then rotate counterclockwise for the third working time and then remain stationary for the fourth working time.

[0088] In this embodiment, when the food processing device is in the second working cycle, the timing device records the third working time and the fourth working time in real time. The timing device can be built into the controller or processor of the food processing device, or the third working time and the fourth working time can be obtained by using a timer in a mobile device connected to the food processing device. Specifically, when receiving a signal from the food processing device in response to a work start instruction, the controller controls the timing device to start timing, and the food processing knife rotates; when the time recorded by the timing device meets the third working time, the timing is stopped and restarted, at which time the food processing knife changes from a rotating state to a stopped state and starts to remain stationary; when the time recorded by the timing device meets the fourth working time, the food processing knife enters the next second working cycle or starts to rotate in the opposite direction.

[0089] The specific storage method of the third working time and the fourth working time can refer to the first working time and the second working time mentioned above. In order to save space, this embodiment will not be described in detail. As an example, the value range of the third working time can be 2min-4min (including the endpoints), for example, the third working time can be 2min, 3min, 4min, etc. The value range of the fourth working time can be 2min-4min (including the endpoints), for example, the second working time can be 2min, 3min, 4min, etc. The above reference value is only an example, and the specific parameter value can be set according to actual use. This embodiment does not make specific restrictions on this.

[0090] It should be noted that the average speed of the brush assembly in the first working cycle is the first speed, and the average speed of the food processing knife in the second working cycle is the second speed, and the second speed is greater than the first speed. Specifically, as an example, the value range of the first speed is 80RPM-150RPM (including the endpoints), and the value range of the second speed is 120RPM-230RPM (including the endpoints). This embodiment does not limit the specific values ​​of the first speed and the second speed.

[0091] By setting the first driving mechanism to drive the food processing knife to rotate according to the preset second working cycle, the contact frequency between the food processing knife and the brush assembly can be increased, which helps to remove stubborn dirt and impurities on the surface of the food processing knife, thereby improving the cleaning efficiency. In addition, the rotating food processing knife and the brush assembly can perform a more thorough cleaning of the food cavity, such as breaking and cleaning the precipitated large volume of food, preventing the brush assembly from being stuck by food during operation, and improving the reliability of the equipment operation.

[0092] In some embodiments, in order to improve the reliability of automatic cleaning of the food processing device, the control method may further include performing a self-check on the device before the food processing device automatically cleans. The self-check may include checking whether the brush assembly is correctly installed on the second drive mechanism, or / and whether the cover is correctly installed on the receiving bucket, or / and whether the food processing knife is correctly connected to the first drive mechanism, or / and whether the amount of water added to the food cavity meets the amount of water required for automatic cleaning.

[0093] Specifically, the controller controls the detection component to detect whether the brush assembly and the second drive mechanism are installed correctly. Before responding to the work start instruction and controlling the second drive mechanism to drive the brush assembly to rotate according to the preset first work cycle, the control method also includes: obtaining relative position information of the brush assembly and the second drive mechanism; when the relative position information indicates that the brush assembly is located in the receiving barrel and is transmission-connected to the second drive mechanism, executing the step of responding to the work start instruction and controlling the second drive mechanism to drive the brush assembly to rotate according to the preset first work cycle.

[0094] The detection component may include a first sensor and a first inductor, one of the first sensor and the first inductor is located on the brush component, and the other is located on the second driving mechanism. This embodiment does not limit the specific types of the first inductor and the first sensor. For example, when the first sensor is a Hall sensor, the first inductor may be a magnet; when the first sensor is an infrared receiver, the first inductor is an infrared transmitter.

[0095] As a specific example, when the first sensor is arranged at one end of the brush assembly close to the second drive mechanism and is a Hall sensor, the first inductor is arranged at one end of the second drive mechanism close to the brush assembly and is a magnet; the controller obtains the first signal value received by the Hall sensor, and compares the first signal value with the first preset signal value to determine the relative position information of the brush assembly and the second drive mechanism. The first signal value is a magnetic field strength value, and the first preset signal value is a preset magnetic field strength range. When the magnetic field strength value is maximum or the magnetic field strength value falls within the preset magnetic field strength range, it indicates that the brush assembly is transmission-connected to the second drive mechanism.

[0096] The detection assembly also includes a first detection unit for detecting whether the brush assembly is located in the storage barrel and a second detection unit for detecting whether the second drive mechanism is correctly installed. The first detection unit and the second detection unit may include the Hall sensor, magnet, infrared receiver, and infrared transmitter mentioned above. In order to save space, this embodiment does not specifically describe the process of determining relative position information through signal strength of the Hall sensor, magnet, infrared receiver, and infrared transmitter. For details, please refer to the relative position information confirmation process of the brush assembly and the second drive mechanism mentioned above.

[0097] It is understandable that the present embodiment is not limited to the Hall sensor, magnet, infrared receiver and infrared transmitter mentioned above, and the first detection unit and the second detection unit may also include a photoelectric sensor or a capacitive sensor. As a specific example, the first detection unit includes a capacitive sensor, which is arranged at one end of the side wall of the storage barrel near the opening. The second drive mechanism is connected to the cover body, and the second drive mechanism is in a state of sealing the opening of the food cavity when connected to the brush assembly. The capacitive sensor detects the capacitance change caused by the approach of the second drive mechanism, thereby determining the installation position of the second drive mechanism. Specifically, when the capacitance detected by the photoelectric sensor is within the preset capacitance range, it means that the second drive mechanism is correctly installed on the cover body. The second detection unit includes a photoelectric sensor, which is located at one end of the food cavity near the bottom wall. The photoelectric sensor is used to detect the light shielding due to the brush assembly being placed in the food cavity to determine the installation position of the brush assembly. When the photoelectric sensor detects that the light is blocked, it indicates that the brush assembly is located in the storage barrel.

[0098] It should be noted that the first preset signal value (such as the preset magnetic field strength range) mentioned above is a parameter value that is pre-fixed in the controller or processor of the food processing device before leaving the factory.

[0099] By providing the above-mentioned detection component to determine whether the brush component and the second driving mechanism are correctly installed, it is possible to reduce the downtime caused by incorrect installation during the automatic cleaning process of the food processing device, thereby ensuring the reliability of the automatic cleaning process of the food processing device, and preventing safety problems caused by incorrect installation of components during the automatic cleaning process.

[0100] In some embodiments, the controller is further used to control the detection assembly to detect whether the cover body correctly covers the food cavity. Specifically, before responding to the work start instruction and controlling the second drive mechanism to drive the brush assembly to rotate according to the preset first work cycle, the control method further includes: obtaining relative position information of the cover body and the storage bucket; when the relative position information indicates that the cover body is connected to the storage bucket and covers the food cavity, executing the step of responding to the work start instruction and controlling the second drive mechanism to drive the brush assembly to rotate according to the preset first work cycle.

[0101] The detection component may include a second sensor and a second inductor, one of the second sensor and the second inductor is located on the cover body, and the other is located at an end of the storage bucket close to the cover body. This embodiment does not limit the specific types of the first inductor and the first sensor. For example, when the first sensor is a Hall sensor, the first inductor may be a magnet; when the first sensor is an infrared receiver, the first inductor is an infrared transmitter, etc. In order to save space, this embodiment does not specifically describe the specific process of obtaining the sensing signal formed by the first and second inductors through the second sensor to determine the relative position information of the cover body and the storage bucket. For details, please refer to the above-mentioned process of confirming the relative position information by the brush assembly and the second drive mechanism.

[0102] The detection assembly also includes a first detection unit for detecting whether the brush assembly is located in the storage barrel and a second detection unit for detecting whether the second drive mechanism is correctly installed. The first detection unit and the second detection unit may include the Hall sensor, magnet, infrared receiver, and infrared transmitter mentioned above. In order to save space, this embodiment does not specifically describe the process of determining relative position information through signal strength of the Hall sensor, magnet, infrared receiver, and infrared transmitter. For details, please refer to the relative position information confirmation process of the brush assembly and the second drive mechanism mentioned above.

[0103] By setting the above-mentioned second sensor and second sensor, it is possible to determine whether the cover body is correctly installed, thereby preventing liquid splashing during the automatic cleaning process of the food processing equipment and reducing shutdown failures caused by incorrect installation during the automatic cleaning process of the food processing equipment, thereby ensuring the reliability of the automatic cleaning process of the food processing equipment and preventing safety problems caused by incorrect installation of components during the automatic cleaning process.

[0104] In some embodiments, the controller is also used to control the detection component to detect whether the amount of water added to the food cavity meets the amount of water required for automatic cleaning. Specifically, before responding to the work start instruction and controlling the second drive mechanism to drive the brush assembly to rotate according to the preset first working cycle, the control method also includes: obtaining the water volume information in the holding bucket, and when the water volume information indicates that the water volume in the holding bucket is greater than or equal to the preset water volume, executing the step of responding to the work start instruction and controlling the second drive mechanism to drive the brush assembly to rotate according to the preset first working cycle. The detection component can specifically obtain the water volume information by detecting the water level in the holding bucket or the weight of the added water. The preset water volume is the water volume value that satisfies the food processing equipment for automatic cleaning. It can be a parameter value or parameter range that is pre-fixed in the controller or processor of the food processing equipment before leaving the factory. The preset water volume can be specifically measured by the weight of the water or other parameters used to characterize the amount of water.

[0105] As an example, the detection component may include a liquid level sensor, which is used to detect the water level in the storage bucket to confirm whether the amount of water in the storage bucket meets the preset water volume or the conditions for automatic cleaning of the food processing equipment. The liquid level sensor is arranged on the side wall surface of the inner tank and is spaced a certain distance from the bottom wall of the inner tank. It determines the water level information by obtaining the signal value returned from the liquid surface or the buoyancy of the sensor. Specifically, the liquid level sensor can be an ultrasonic liquid level sensor, which transmits ultrasonic pulses to the liquid surface and receives the reflected sound waves. The water level information is obtained by calculating the round trip time of the sound wave. When the round trip time of the sound wave falls within the predetermined time range or the return time is the shortest, it indicates that the amount of water in the storage bucket meets the amount of water required for automatic cleaning of the food processing equipment.

[0106] In other embodiments, the detection component may also be a pressure sensor, which is used to detect the weight change of the amount of water added to the holding barrel during the food processing process, so as to confirm whether the amount of water meets the conditions for automatic cleaning of the food processing equipment. In this embodiment, the pressure sensor is arranged at the bottom of the holding barrel to detect the weight of the amount of water added to the food cavity. Specifically, the number of the pressure sensor can be one, which is arranged at the center of the bottom of the food cavity. At this time, the value detected by the pressure sensor is the weight of the amount of water added to the food cavity.

[0107] The controller obtains weight information to detect whether the amount of water added meets the conditions for automatic cleaning. When the weight information falls within the predetermined water volume range, it indicates that the water volume meets the conditions for the food processing device to automatically clean. At this time, the controller controls the food processing device to respond to the work start instruction and controls the second drive mechanism to drive the brush assembly to rotate according to the preset first working cycle. As an example, the value range of the predetermined water volume can be 1000ml-2000ml (including the endpoints), for example, 1000ml, 1200ml, 1500ml, 2000ml, etc. It should be noted that the predetermined water volume can also be other numerical ranges, and this embodiment does not impose specific restrictions on this.

[0108] By setting the above-mentioned detection component to detect whether the amount of water added meets the conditions for automatic cleaning, the reliability and cleaning effect of the automatic cleaning of the food quantity equipment can be improved.
