DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0023] If certain terms are used in the specification and claims to refer to specific components, those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not distinguish components based on differences in name, but rather on differences in their functionality. For example, the term "including" used throughout the specification and claims is an open-ended term and should be interpreted as meaning "including but not limited to." "Substantially" means that those skilled in the art can solve the technical problem within a certain error range and achieve a substantial technical effect.

[0024] See also Figure 1 The present embodiment provides a food processing device 100 for processing food. For example, the device may have functions such as blending and / or breaking food. This specification does not limit the specific type of the food processing device 100. For example, the food processing device 100 may be a blender, a food processor, an ice cream maker, etc. In this embodiment, the food processing device 100 is an ice cream maker as an example for further description.

[0025] This specification does not limit the specific structure of the food processing device 100. For example, the food processing device 100 may include a housing 110, a refrigeration module, and a mixing barrel module, wherein the mixing barrel module and the refrigeration module are both disposed within the housing 110. Ingredients are stirred in the mixing barrel module, and the refrigeration module is used to cool the ingredients stirred in the mixing barrel module to produce finished ice cream. This specification does not limit the cooling method of the refrigeration module. The refrigeration module may use a compressor for cooling or a refrigerant for cooling.

[0026] Please also see Figure 1 and Figure 2In this embodiment, the mixing barrel module of the food processing device 100 may include a shell 10, an inner pot 30, a stirring mechanism 50 and a first cooling member 70. The shell 10 has an inner pot cavity 121 and a refrigeration cavity 123. The inner pot cavity 121 surrounds the refrigeration cavity 123. The shell 10 is provided with a mounting platform 16. The inner pot cavity 121 and the refrigeration cavity 123 are separated by the mounting platform 16. The inner pot 30 is arranged in the inner pot cavity 121, and the inner pot 30 is stacked on the mounting platform 16. Here, "stacked" is understood to mean that the inner pot 30 and the mounting platform 16 can be partially overlapped on the surface, or there is a slight gap between the inner pot 30 and the mounting platform 16, or the two are directly fitted. The stirring mechanism 50 includes a transmission shaft 52 and a stirring assembly 54. The stirring assembly 54 is transmission-connected to the transmission shaft 52 and is located in the inner pot 30. The transmission shaft 52 passes through the refrigeration cavity 123. The first cooling member 70 is arranged in the refrigeration cavity 123.

[0027] In this embodiment, the housing 10 has an inner chamber 121 and a refrigeration chamber 123. The inner chamber 121 surrounds the refrigeration chamber 123. The first cooling member 70 is disposed in the refrigeration chamber 123, and the inner chamber 30 is disposed in the inner chamber 121. That is, the first cooling member 70 is inside the inner chamber 30. When the food processing device 100 is in use, the first cooling member 70 can cool the food in the inner chamber 30 from the center of the inner chamber 30. Compared with a refrigeration solution that cools from the periphery and bottom, the refrigeration efficiency is greatly improved, thereby improving the processing efficiency of the food processing device 100. Moreover, since the first cooling member 70 cools from the inside, the size of the inner chamber 30 and the housing 10 is not limited by it. The size of the inner chamber 30 and the housing 10 can be increased to a certain extent, thereby increasing the single processing volume of the food processing device 100.

[0028] In this application, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, these terms may refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; internal communication between two components; or mere surface contact. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0029] In this embodiment, the housing 10 is used to house the inner container 30 and is generally cylindrical in shape. In other embodiments, the housing 10 may also be square, barrel-shaped, or have an irregular shape. The housing 10 has an open end. The mixing drum module of the food processing device 100 may also include a cover 20. The housing 10 has an opening 11 communicating with the inner container cavity 121. The cover 20 is movably connected to the housing 10 at the opening 11 and is capable of shielding the inner container cavity 121. In this embodiment, the cover 20 is movably connected to the housing 10 and seals the inner container cavity 121 to prevent dust and impurities from contacting the food inside the inner container cavity 121. The cover 20 also prevents food from splashing during the mixing or blending process of the food processing device 100. For example, the cover 20 may be hingedly mounted to the opening 11 of the mixing drum 10. Alternatively, the cover 20 may be detachably connected to the housing 10 and completely detachable from the housing 10, although this embodiment is not particularly limited thereto.

[0030] In order to improve the cooling effect of the food in the inner liner 30, the refrigeration module of the food processing device 100 may include a second cooling member 90, and the second cooling member 90 is arranged in the shell 10. Specifically, the shell 10 may include an inner shell 12 and an outer shell 14, the outer shell 14 is sleeved on the outside of the inner shell 12 and fixedly connected to the inner shell 12, and the inner liner cavity 121 is arranged in the inner shell 12. The outer shell 14 and the inner shell 12 are spaced apart to jointly define a mounting cavity 141, and the second cooling member 90 is arranged in the mounting cavity 141, which is used to cool the inner liner 30 in the inner liner cavity 121. The second cooling member 90 cools the food in the inner liner 30 from the outside of the inner liner 30, and the first cooling member 70 cools the food from the inside of the inner liner 30, which improves the consistency of the taste of the inner and outer layers of the food in the inner liner 30 and also improves the production efficiency.

[0031] This specification does not limit the specific structure of the second cooling member 90. For example, the second cooling member 90 can be a cooling tube, or the second cooling member 90 is not a specific structure, but a refrigerant liquid filled in the installation cavity 141. As an example, the second cooling member 90 is an evaporating coil, and the refrigeration module can also include a compressor and a condenser. The evaporating coil (second cooling member 90) is arranged in the installation cavity 141 and is surrounded by the outer wall of the inner shell 12. The inner shell 12 can be made of a material with good thermal conductivity. For example, the inner shell 12 can be made of aluminum, aluminum alloy and other materials. The evaporating coil is used to accommodate a heat exchange medium, and the heat exchange medium can be a refrigerant such as water, Freon, propane, etc. The compressor and the condenser are both arranged in the casing 110, the compressor is connected to the evaporating coil, and the condenser is connected to the compressor. The evaporating coil absorbs the heat of the food in the inner pot 30, and the heat exchange medium in the evaporating coil changes from liquid to gas to cool the food in the inner pot 30. The gaseous heat exchange medium is then cooled by the compressor and condenser and turned back into liquid heat exchange medium. The liquid heat exchange medium returns to the evaporating coil to continue absorbing heat and cooling. The above process is repeated continuously to achieve continuous cooling of the food in the inner pot 30, so that the food can be made into finished ice cream.

[0032] The space between the outer shell 14 and the inner shell 12 may also be filled with insulation material to improve cooling efficiency. In this embodiment, the food processing device 100 may further include a foam layer 13 disposed within the mounting cavity 141. The foam layer 13 provides thermal insulation and assists in securing the second cooling element 90. This specification does not limit the specific foam material of the foam layer 13. For example, the foam material may include any of the following: polystyrene foam board, polyurethane foam board, or polyethylene foam board.

[0033] Please also see Figure 3 and Figure 4In this embodiment, the inner shell 12 is roughly in the shape of a barrel with one end open. The inner shell 12 may include an outer peripheral wall 122, a bottom wall 124 and the above-mentioned mounting platform 16. The bottom wall 124 is connected to one end of the outer peripheral wall 122, and the outer peripheral wall 122 surrounds the mounting platform 16. The outer peripheral wall 122, the bottom wall 124 and the mounting platform 16 jointly define the inner tank cavity 121. The middle portion of the bottom wall 124 protrudes inward to form the mounting platform 16. The mounting platform 16 is roughly in the shape of a hollow truncated cone. The inner cavity of the mounting platform 16 is the above-mentioned refrigeration cavity 123. The mounting platform 16 has an open end 161, which is located at the bottom of the inner shell 12. The open end of the inner shell 12 is turned outward to form an outer flange, which protrudes relative to the peripheral wall of the inner shell 12 and is connected to one end of the outer shell 14. The outer shell 14 is sleeved over the outer circumferential wall 122 and spaced apart from the outer circumferential wall 122. The end of the outer shell 14 near the open end of the inner shell 12 is connected to the outer flange of the inner shell 12, so that the inner circumferential wall of the outer shell 14 is spaced apart from the outer circumferential wall 122 to form the installation cavity 141. The end of the outer shell 14 away from the open end of the inner liner 30 can be provided with an inner flange. The outer flange of the outer shell 14 protrudes relative to the inner circumferential wall of the outer shell 14 to connect with the bottom wall 124. The outer flange of the inner shell 12 and the inner flange of the outer shell 14 jointly enclose the installation cavity 141.

[0034] This specification does not limit the inner diameter of the inner shell 12; the inner diameter of the inner shell 12 can be constant or gradually varying. In this embodiment, the peripheral wall of the inner shell 12 extends in an inclined direction relative to the transmission shaft 52. The inner diameter of the open end of the inner shell 12 is slightly larger than the inner diameter of the bottom end of the inner shell 12, and the inner diameter of the inner shell 12 gradually decreases along the axial direction of the transmission shaft 52. The peripheral wall of the mounting platform 16 also extends in an inclined direction relative to the transmission shaft 52. The inner and outer diameters of the mounting platform 16 gradually increase along the axial direction of the transmission shaft 52, and the inner and outer diameters of the open end 161 of the mounting platform 16 are slightly larger than the inner and outer diameters of the other end.

[0035] The liner 30 is disposed within the liner cavity 121 and is used to hold the ingredients needed to make ice cream, such as cream, butter, cheese, nuts, and fruit. The liner 30 not only holds the ingredients to be processed but also provides a place for them to be processed. The liner 30 can be barrel-shaped, conforming to the shape of the liner cavity 121. For example, the liner 30 can include an outer peripheral wall, a bottom wall, and a mounting platform. The bottom wall of the liner 30 is connected to the outer peripheral wall, and the outer peripheral wall of the liner 30 surrounds the mounting platform. A small gap can be provided between the outer peripheral wall 122 of the liner 30, and the bottom wall of the liner 30 abuts against the bottom wall 124. The liner 30 is stacked on the mounting platform 16. That is, the liner 30 is also barrel-shaped with one end open, and the bottom wall of the liner 30 also protrudes inward to form a mounting platform. The shape of the mounting platform is the same as that of the mounting platform 16, and the mounting platform 16 is accommodated within the mounting platform of the liner 30 and fits in place with the mounting platform. The stirring chamber of the inner container 30 surrounds the refrigeration chamber 123 , and the first cooling member 70 can cool the food in the inner container 30 from the middle of the inner container 30 .

[0036] In this embodiment, the food processing apparatus 100 may further include a connecting pipe 40, which extends through the refrigeration chamber 123 and is used to mount a drive shaft 52. The drive shaft 52 extends through the connecting pipe 40, and the first cooling element 70 is disposed outside the connecting pipe 40. The connecting pipe 40 may include a tube body 41 and a cover plate 43. The tube body 41 is disposed in the refrigeration chamber 123 through an open end 161 and is spaced apart from the inner wall of the mounting platform 16. The tube body 41 is passed through at both ends and is used to mount the drive shaft 52. The cover plate 43 surrounds and is connected to the peripheral wall of the tube body 41 near the open end 161 and protrudes relative to the peripheral wall. The cover plate 43 is generally annular and is located outside the refrigeration chamber 123 and is connected to the bottom of the inner container 30 to seal the open end 161. The cover plate 43 can be fixed to the bottom of the inner shell 12 using fasteners such as bolts and nuts. The inner wall of the mounting platform 16, the outer wall of the tube body 41, and the cover plate 43 collectively define the refrigeration chamber 123.

[0037] The first cooling member 70 is located in the refrigeration cavity 123, and can be specifically arranged between the inner wall surface of the mounting platform 16 and the outer wall of the tube body 41. This specification does not limit the specific structure of the first cooling member 70. For example, the first cooling member 70 can be a cooling tube, or the first cooling member 70 is not a specific structure, but a refrigerant liquid filled in the refrigeration cavity 123. As an example, the first cooling member 70 is an evaporating coil, and the evaporating coil (first cooling member 70) is arranged in the refrigeration cavity 123 and surrounds the outer wall of the tube body 41. The evaporating coil is used to accommodate a heat exchange medium, which can be a refrigerant such as water, Freon, propane, etc. The cover plate 43 can be provided with a clearance hole for the inlet and outlet pipes of the evaporating coil (first cooling member 70). In other embodiments, the space between the first cooling member 70 and the inner circumferential wall of the mounting platform 16 can be filled with a heat-conducting material, such as thermal grease.

[0038] In this embodiment, the transmission shaft 52 is disposed within the tube body 41. One end of the transmission shaft 52 is disposed through the mounting platform 16 and the inner container 30 and is connected to the stirring assembly 54. The other end is connected to the driving member of the stirring mechanism 50. Specifically, the end of the mounting platform 16 away from the open end 161 can be provided with a mounting hole that communicates with the inner cavity of the tube body 41. Similarly, the inner container 30 is also provided with a through hole corresponding to the mounting hole on the mounting platform 16. The transmission shaft 52 extends into the stirring space within the inner container 30 through the mounting hole on the mounting platform 16 and the through hole on the inner container 30. The stirring assembly 54 is in driving connection with the end of the transmission shaft 52 that extends into the inner container 30.

[0039] In this embodiment, the end of the tube body 41 away from the cover plate 43 abuts against the inner wall of the mounting platform 16. To improve the sealing of the refrigeration chamber 123, a seal may be provided between the tube body 41 and the mounting platform 16. For example, a sealing sleeve 45 may be provided between the tube body 41 and the mounting platform 16. The sealing sleeve 45 is disposed over the drive shaft 52 and is received within a mounting hole on the mounting platform 16 for the drive shaft 52 to pass through. The sealing sleeve 45 may have an irregular shape. For example, the outer diameter of the sealing sleeve 45 received at the end of the tube body 41 may be larger to fill the space between the inner wall of the tube body 41 and the drive shaft 52, thereby improving the sealing performance. The sealing sleeve 45 not only improves the sealing between the inner liner 30 and the tube body 41, but also improves the sealing of the refrigeration chamber 123.

[0040] To reduce the risk of liquid within the inner pot 30 flooding the connection between the stirring assembly 54 and the drive shaft 52 during processing, in this embodiment, the cover 20 is provided with a drive shaft hole 21. At least one of one end of the drive shaft 52 and the rotating shaft of the stirring assembly 54 is accommodated within the drive shaft hole 21. The drive shaft hole 21 is recessed relative to the surface of the cover 20 toward the inner pot 30, and at least a portion of the stirring assembly 54 is accommodated within the drive shaft hole 21. The drive connection between the drive shaft 52 and the stirring assembly 54 is accommodated within the drive shaft hole 21, which reduces the impact of the stirring of the ingredients within the inner pot 30 during stirring and improves the stability of the stirring mechanism 50.

[0041] The transmission shaft 52 is rotatably disposed within the tubular body 41. In this embodiment, the transmission shaft 52 is rotatably connected to the tubular body 41 via a bearing 521. The bearing 521 is sleeved around the transmission shaft 52 and positioned within the tubular body 41. Two bearings 521 may be provided, one at each end of the tubular body 41, with the diameter of the bearing 521 closer to the cover plate 43 being larger than the diameter of the other bearing 521.

[0042] In this embodiment, the stirring mechanism 50 may further include a driving member 56, which is disposed on a side of the housing 10 away from the cover 20. One end of the transmission shaft 52 extends through the connecting pipe 40 and is in transmission connection with the driving member 56. The driving member 56 is used to drive the stirring assembly 54 via the transmission shaft 52 to stir the food in the inner pot 30. This specification does not limit the specific structure of the driving member 56. For example, the driving member 56 may include a driving source such as a rotary motor or a rotary cylinder, or the driving member 56 may also include at least one of a coupling, a gear, a turbine, a worm, and other transmission structures.

[0043] To facilitate installation of the driving member 56, the food processing apparatus 100 may further include a bracket 60, which is connected to the bottom of the housing 110. The bracket 60 may also include a support column or other structure for supporting the housing 10. The driving member 56 is connected to a side of the bracket 60 facing away from the housing 10 and is spaced apart from the bottom of the housing 110.

[0044] The transmission shaft 52 is connected to the output end of the driver 56. This specification does not limit the specific connection method between the transmission shaft 52 and the output end of the driver 56. For example, the transmission shaft 52 and the output end of the driver 56 can be connected by fasteners such as flanges. In the present embodiment, the output ends of the transmission shaft 52 and the driver 56 are connected by a coupling. As an example, the output ends of the transmission shaft 52 and the driver 56 are coaxial, one end of the transmission shaft 52 is provided with a coupling male end, and the output end of the driver 56 is provided with a coupling female end, and the coupling male end and the coupling female end are engaged to receive the torsion from the driver 56. Furthermore, a cushioning rubber pad can be provided between the coupling male end and the coupling female end. The cushioning rubber pad has a force buffering effect and can also eliminate the shaft runout caused by the different axes of the output end of the driver 56 and the transmission shaft 52 to a certain extent, thereby increasing precision redundancy and reducing shock and noise.

[0045] Please also see Figure 2 and Figure 5 In this embodiment, the stirring assembly 54 is disposed in the inner pot 30 and is used to stir the food in the inner pot 30. The stirring assembly 54 may include a connecting member 541, a first stirring blade 543, and a second stirring blade 545. The connecting member 541 is connected to the transmission shaft 52. The first stirring blade 543 and the second stirring blade 545 are both disposed on the side of the connecting member 541 facing away from the cover 20 and are spaced apart in the radial direction of the inner pot 30. The first stirring blade 543 is located between the mounting platform 16 and the second stirring blade 545. The first stirring blade 543 and the second stirring blade 545 are used to stir the food inside and outside the inner pot 30, respectively, thereby improving the stirring efficiency.

[0046] The connecting member 541 is generally in the shape of an elongated plate. It is non-rotatably connected to the end of the transmission shaft 52 near the lid 20 and extends radially along the inner container 30. It should be understood that the "non-rotatable connection" between the connecting member 541 and the transmission shaft 52 should be understood as meaning that the connecting member 541 and the transmission shaft 52 are relatively fixed, and the connecting member 541 can rotate with the rotation of the transmission shaft 52. In this embodiment, a transmission connection portion 523 is provided at the end of the transmission shaft 52 near the lid 20. The transmission shaft 52 is non-rotatably connected to the connecting member 541 via the transmission connection portion 523. A transmission hole 5412 is provided in the middle of the connecting member 541, coaxial with the transmission shaft 52. The transmission connection portion 523 is embedded in the transmission hole 5412. To achieve the non-rotatable connection, the cross-section of the transmission connection portion 523 is non-circular, such as a hexagonal, triangular, or other irregular shape.
