[0001] This disclosure relates to the structure of food processing equipment, and more specifically to an attachment device for food processing equipment and food processing equipment including the attachment device. Background Technology

[0002] Nowadays, food processing equipment such as soft-serve ice cream machines and smoothie machines are increasingly widely used in homes and shopping malls. These machines produce frozen foods such as soft-serve ice cream and smoothies, providing people with more food choices and enjoyment. In these food processing machines, pure liquids or mixtures of liquid and ice can be transformed into frozen foods through stirring and cooling, and then dispensed into containers. Utility Model Content

[0039] In some non-limiting embodiments of this disclosure, the substrate includes a plurality of separate parts that can be assembled together in a manner that allows them to be detached from each other, and defines the chamber between the plurality of separate parts.

[0040] In some non-limiting embodiments of this disclosure, a chamber is defined between every two adjacent portions of the plurality of portions.

[0041] In some non-limiting embodiments of this disclosure, one of two adjacent split parts is provided with a plug-in portion, and the other of two adjacent split parts is provided with a plug-in hole, wherein the plug-in portion is inserted into the plug-in hole so that the two adjacent split parts are fixed to each other.

[0042] In some non-limiting embodiments of this disclosure, the chamber is configured to be spherical or elongated.

[0043] This disclosure also provides a food processing device, including a main unit and an attachment device for the food processing device as described in any of the above technical solutions, wherein the attachment device is detachably installed on the main unit.

[0048] In this way, after the attachment device is installed on the main unit of the food processing equipment, the cooling efficiency (especially the freezing efficiency) of the food processing equipment including the attachment device in cooling the liquid in the chamber can be improved, thereby reducing the time required to cool or even freeze the liquid in the chamber.

[0049] Furthermore, in some non-limiting embodiments of this disclosure, the attachment device can be drive-connected to the drive mechanism of the food processing equipment. This allows the attachment device to be stationary while the liquid inside the chamber is cooled (especially frozen) by the evaporator on the outside; alternatively, the attachment device can be driven to rotate while the liquid inside the chamber is cooled by the evaporator on the outside. This not only increases the flexibility of the cooling method of the attachment device but also significantly improves the cooling efficiency (especially freezing efficiency) of the food processing equipment including the attachment device in cooling the liquid inside the chamber, thereby reducing the time required to cool or even freeze the liquid inside the chamber. Moreover, while the attachment device is driven to rotate, during the cooling process of the liquid inside the chamber by the evaporator, air bubbles in the liquid (e.g., pure water) inside the chamber do not disperse within the liquid but move towards the outside of the liquid. This is beneficial for forming frozen products (e.g., popsicles, ice cubes) with high transparency and few or no air bubbles. Attached Figure Description

[0119] In this disclosure, "approximately" means that the conditions described herein can be considered to be met within a reasonable margin of error recognized by a person skilled in the art, and the following description uses this expression to convey a similar meaning.

[0120] In this disclosure, "transmission connection" means a connection between two components that can transmit torque, including direct and indirect connections between the two components.

[0121] The following description, in conjunction with the accompanying drawings, describes attachment devices for food processing equipment according to some non-limiting embodiments of the present disclosure.

[0122] See Figures 6A to 6C and Figure 7D The attachment device AM for food processing equipment according to this disclosure can be detachably mounted to the main unit MB of the food processing equipment and positioned inside the evaporator 401 of the cooling system 40 of the main unit MB. This food processing equipment can be a soft-serve ice cream machine, a smoothie machine, or other types of food processing equipment. Figures 1A to 1D As shown, the attachment device AM for food processing equipment according to some non-limiting embodiments of the present disclosure may include a base 1, a first connecting portion 2, and a second connecting portion 3 assembled together. The first connecting portion 2 and the second connecting portion 3 can be connected to the base 1, thereby forming a modular structure.

[0123] In some non-limiting embodiments of this disclosure, such as Figure 1C and Figure 1D As shown, the substrate 1 includes multiple chambers 1c for receiving liquids, which cannot receive, for example, the stirring mechanism of a stirrer 302 in a food processing device. These chambers 1c may have the same shape, and each chamber 1c may be formed as a strip shape with various cross-sectional shapes. Further, each chamber 1c may be configured to be openable and closable. When a chamber 1c is in the open state, liquid can be added to the chamber 1c; when a chamber 1c is in the closed state, the liquid inside the chamber 1c will not leak out and the liquid inside the chamber 1c can be cooled (e.g., frozen). Specifically, in some non-limiting embodiments of this disclosure, such as... Figures 1A to 1DAs shown, the base 1 may include a main body 11 and a plurality of storage components 12. The plurality of storage components 12 may be detachably assembled to the main body 11, and each storage component 12 defines a chamber 1c with the main body 11.

[0124] In some non-limiting embodiments of this disclosure, the main body 11 may be made of a rigid material such as metal or plastic to have sufficient structural strength. Figures 1C to 2D As shown, the main body 11 is integrally formed as a structure with a central axis. Figure 2C As shown, in any cross-section of the main body 11 perpendicular to the centerline axis, the main body 11 may have a structure that is centrally symmetrical about the intersection point of the cross-section with the central axis.

[0125] like Figures 2A to 2C As shown, the outer periphery of the main body 11 can be formed with a plurality of mounting slots 11c for mounting the housing assembly 12. The shape of each mounting slot 11c can be configured to match a portion of the outer periphery of the housing tube 121 of the housing assembly 12, thereby allowing the housing tube 121 of the housing assembly 12 to be mounted in the mounting slot 11c without undesirable movement. The plurality of mounting slots 11c can be evenly distributed at intervals along the circumferential direction D3 of the main body 11. By positioning the mounting slots 11c on the outer periphery of the main body 11 and distributing them evenly, the chamber 1c of the housing assembly 12 can be positioned on the outer periphery of the main body 11. Thus, with the attachment device AM installed inside the evaporator 401, the chamber 1c defined by the base 1 can be positioned as close as possible to the evaporator 401, which further facilitates cooling (e.g., freezing) of the liquid in the chamber 1c.

[0126] like Figures 2A to 2DAs shown, the mounting groove 11c may have a first opening 11o1 and a second opening 11o2. The first opening 11o1 is open to the other side of the main body 11 along the axial direction D1, and the first opening 11o1 is open to the outer side of the main body 11 along the radial direction D2. Thus, the mounting groove 11c can be configured to be open to the other side along the axial direction and to the outer side radially. The housing assembly 12 can be inserted into and removed from the mounting groove 11c via the first opening 11o1, thereby facilitating the installation and removal of the housing assembly 12 from the main body 11. Since the mounting groove 11c has the second opening 11o2, the main body 11 itself can omit the structure that closes the mounting groove 11c from the outer side radially, thereby reducing the radial dimension of the main body 11 and significantly reducing the possibility of the attachment device AM scratching against components located on its outer side (e.g., the evaporator 401) during rotation. In addition, the main body 11 may include an axial wall portion 112 opposite to the first opening 11o1. Axial wall portions 112 are positioned on one side of the main body portion 11 along the axial direction D1. Each axial wall portion 112 can correspond to and abut against a storage assembly 12. When the axial wall portion 112 abuts against the corresponding storage assembly 12, the axial wall portion 112 can close the opening (second opening 121o2) of the storage cylinder 121 of the storage assembly 12, so that the axial wall portion 112 and the storage assembly 12 can jointly surround and define the chamber 1c. In this way, on the one hand, the axial wall portion 112 is used to define the position of the storage assembly 12 along the axial direction D1 of the main body portion 11; on the other hand, the storage assembly 12 and the axial wall portion 112 cooperate to form the chamber 1c, and the storage assembly 12 does not need to have a structure to close the corresponding opening, thus reducing the axial dimension of the storage assembly 12 and the entire attachment device AM. In addition, the main body portion 11 may include a protrusion 113 formed on the axial wall portion 112. The protrusion 113 can protrude relative to the axial wall portion 112 toward the opening of the storage cylinder 121, and the protrusion 113 can fit with the shape of the opening of the storage cylinder 121. In this way, when the storage assembly 12 is installed in the mounting groove 11c and the axial wall portion 112 abuts against the storage cylinder 121 of the storage assembly 12, the protrusion 113 can protrude into the interior of the storage cylinder 121 and can better seal the opening of the storage cylinder 121, preventing liquid from undesirably leaking out from the opening.

[0127] To prevent the storage component 12 from detaching from the second slot 11o2 after being installed in the mounting slot 11c, and to prevent the storage component 12 from shifting to the circumferential sides, such as Figures 2A to 2C As shown, at both circumferential ends of each mounting groove 11c, the main body 11 may include a limiting portion 111 protruding inward toward the mounting groove 11c. The limiting portion 111 may be configured as an arc-shaped structure protruding inward toward the mounting groove 11c. The two limiting portions 111 can further stably hold the housing assembly 12 in the mounting groove 11c.

[0128] In order to fix the first connecting part 2 and the second connecting part 3 to the main body part 11, such as Figures 1C to 2D As shown, the main body 11 may have a first mounting hole 11h1 opening to one axial side and a second mounting hole 11h2 opening to the other axial side. The first mounting hole 11h1 and the second mounting hole 11h2 may be arranged coaxially, and the central axis of these two mounting holes 11h1 and 11h2 may be aligned with the central axis of the main body 11. The first mounting hole 11h1 and the second mounting hole 11h2 may be blind holes with a square cross-section. Further, the shape and size of the first mounting hole 11h1 may match the shape and size of the first body part 21 of the first connecting part 2, such that the first body part 21 of the first connecting part 2 can be inserted into the first mounting hole 11h1 in an interference fit, for example, and fixed together with the main body 11. The shape and size of the second mounting hole 11h2 may match the shape and size of the second body part 34 of the second connecting part 3, such that the second body part 34 of the second connecting part 3 can be inserted into the second mounting hole 11h2 in an interference fit, for example, and fixed together with the main body 11. By adopting a split design and then fixing and assembling them together, the processing and manufacturing of the main body 11 can be facilitated.

[0129] In some non-limiting embodiments of this disclosure, such as Figures 1A to 1D as well as Figure 3A and Figure 3B As shown, each storage component 12 can be detachably installed in a corresponding mounting slot 11c, and each storage component 12 can define a chamber 1c together with the main body 11. In other alternatives, the storage component 12 may not define a chamber 1c together with the main body 11, but may form a chamber 1c using its own structure. Furthermore, by using multiple storage components 12, the attachment device AM of this disclosure can form the required number of chambers 1c as needed. These chambers 1c are independent of each other, so the liquids within these chambers 1c will not affect each other. Moreover, each storage component 12 can be detached from the main body 11 to operate on the chamber 1c separately, such as adding liquid, removing frozen products, and cleaning. In some non-limiting embodiments of this disclosure, such as... Figures 3A to 3G As shown, the storage assembly 12 may include a storage tube 121 and a cover 122 that can be detachably assembled together.

[0130] The receiving cylinder 121 can be made of a rigid material with good thermal conductivity, such as metal, and its wall thickness can be constructed to be less than 0.8 mm. This ensures sufficient structural strength while further improving the cooling efficiency of the liquid in the chamber 1c. However, to achieve a so-called directional freezing effect in the liquid within the receiving cylinder 121, it can also be made of other materials, such as silicone plastic. This facilitates the movement of air bubbles or impurities in the liquid towards one side, thereby forming bubble-free or low-bubble frozen products (e.g., popsicles, ice cubes) within the chamber 1c. Alternatively, a metal receiving cylinder 121 can be equipped with heat-insulating accessories to achieve a certain degree of heat insulation, thus also achieving a directional freezing effect and forming bubble-free or low-bubble frozen products within the chamber 1c. Figures 3A to 3D As shown, the storage cylinder 121 can be formed into a hollow shape extending along the axial direction D1. The storage cylinder 121 may include a first opening 121o1 and a second opening 121o2. The first opening 121o1 can open towards the opposite side of the main body 11 along the axial direction, and the second opening 121o2 can open towards one side of the main body 11 along the axial direction. The cover 122 can be detachably installed on the storage cylinder 121. When the cover 122 is detached from the storage cylinder 121, the first opening 121o1 can be open, allowing the user to add liquid into the chamber 1c through the first opening 121o1. When the cover 122 is installed on the storage cylinder 121, the first opening 121o1 can be closed, preventing liquid leakage from the first opening 121o1. Further, as... Figure 1C and Figure 1D As shown, with the storage tube 121 of the storage assembly 12 installed in the mounting groove 11c of the main body 11, the storage tube 121 abuts against the axial wall portion 112 of the main body 11, and the axial wall portion 112 and the protrusion 113 effectively seal the second opening 121o2, thereby preventing liquid from leaking out of the second opening 121o2. Moreover, since the storage tube 121 itself omits the structure for sealing the second opening 121o2, the axial dimension of the storage tube 121 can be reduced, that is, the axial dimension of the storage assembly 12 and the entire attachment device AM can be reduced.

[0131] like Figure 1C , Figure 1D , Figures 3A to 3DAs shown, the shape of the radially inner portion of the outer peripheral wall of the storage tube 121 can match the shape of the mounting groove 11c of the main body 11, thereby allowing the storage tube 121 to be smoothly inserted into the mounting groove 11c. Furthermore, after the storage tube 121 is inserted into the mounting groove 11c, the radially outer portion of the outer peripheral wall of the storage tube 121 (that is, the portion exposed from the second slot 11o2) can be approximately located on the same cylindrical surface as the radially outermost portion of the main body 11. In other words, the entire outer peripheral surface of the base 1 is approximately located on the same cylindrical surface, thereby significantly reducing the possibility of the base 1 scratching against components located outside it (such as the evaporator 401) during rotation.

[0132] like Figure 3A , Figure 3B , Figures 3E to 3G As shown, the cover 122 may include a flange 1221, an insertion portion 1222, a sealing portion 1223, and a handle portion 1224. The flange 1221, insertion portion 1222, and handle portion 1224 can be integrally formed to be fixedly connected together. The flange 1221 may be formed as a protruding flange structure relative to the insertion portion 1222 and the handle portion 1224. When the cover 122 is assembled with the storage tube 121, the flange 1221 can abut against the other axial end of the storage tube 121, thereby closing the first opening 121o1 of the storage tube 121. Furthermore, the insertion portion 1222 and the handle portion 1224 may be located on opposite axial sides of the flange 1221. When the cover 122 is assembled with the storage tube 121, the insertion portion 1222 can be inserted entirely into the storage tube 121. More specifically, the insertion portion 1222 may include an integrally formed mounting portion 12221 and a rod-shaped portion 12222. The mounting portion 12221 may be directly connected to the flange portion 1221, and the mounting portion 12221 may be located between the flange portion 1221 and the rod-shaped portion 12222. Further, the mounting portion 12221 may be formed with an annular groove 12221c, and the sealing portion 1223 may be fitted into the annular groove 12221c, thereby the mounting portion 12221 can stably support the sealing portion 1223. The rod-shaped portion 12222 may extend linearly from the mounting portion 12221 for a sufficient length in a direction away from the flange portion 1221, but the rod-shaped portion 12222 does not abut against the protrusion 113 of the main body portion 11, and the rod-shaped portion 12222 is formed with a plurality of holes 12222h arranged at intervals in its extending direction. Therefore, the rod-shaped portion 12222 can be firmly attached to the frozen product, allowing the frozen product to be removed from the storage cylinder 121 via the cover 122. Furthermore, the liquid added to the chamber 1c can flow into the multiple holes 12222h, further strengthening the attachment between the frozen product and the rod-shaped portion 12222, thus facilitating the removal of the frozen product from the storage cylinder 121 using the cover 122.

[0133] In order to ensure that the insertion part 1222 can reliably close the first opening 121o1 of the storage tube 121, such as Figure 1C , Figure 1D , Figures 3E to 3G As shown, the sealing part 1223 can be installed on the insertion part 1222 and can contact and seal with the storage tube 121. The sealing part 1223 can be integrally molded from an elastic material such as rubber. Specifically, the sealing part 1223 can include a plurality of annular sealing lips 12231 and annular portions 12232. The plurality of sealing lips 12231 are arranged at intervals, and the plurality of sealing lips 12231 are disposed on the outer peripheral surface of the annular portions 12232, and each sealing lip 12231 contacts and seals with the storage tube 121. In this way, by using the cover 122 with the above-described structure, the sealing part 1223 including the plurality of sealing lips 12231 can sufficiently ensure the closure of the first opening 121o1 of the storage tube 121, effectively preventing liquid from leaking out of the first opening 121o1. The handle part 1224 can be directly fixedly connected to the flange part 1221 and can extend from the flange part 1221 in a direction away from the insertion part 1222. With the lid 122 and the storage tube 121 assembled together, the handle 1224 can be located outside the storage tube 121. To facilitate operation of the handle 1224, a finger ring is formed at the end of the handle 1224 away from the flange 1221, allowing the user to insert their finger into the finger ring and apply force to the handle 1224. In this way, the lid 122 and the frozen product attached to the lid 122 can be easily removed from the storage tube 121 via the handle 1224.

[0134] In some non-limiting embodiments of this disclosure, the first connecting portion 2 and the second connecting portion 3 may be made of the same material as the main body portion 11. For example... Figures 1A to 1D as well as Figures 4A to 4D As shown, both the first connecting part 2 and the second connecting part 3 can be fixedly connected to the base 1. The second connecting part 3 and the first connecting part 2 can be located on opposite sides in the axial direction D1. The first connecting part 2 and the second connecting part 3 can be configured to be supported by the main unit MB of the food processing equipment, thereby allowing the attachment device AM to be connected to the main unit MB of the food processing equipment (see...). Figure 7D The first connecting part 2 may include a transmission hole 21h, and the second connecting part 3 may include a transmission rod part 31. When the first connecting part 2, the second connecting part 3, and the main body 11 are assembled in place, the transmission rod part 31 and the transmission hole 21h can be arranged coaxially, and the central axes of both the transmission rod part 31 and the transmission hole 21h can coincide with the central axis of the main body 11. See also... Figure 7DThe transmission rod 31 can be inserted into the support hole 101h of the main unit MB of the food processing equipment, and the transmission hole 21h can cooperate with the output shaft 3012 of the drive device 301. In this way, the first connecting part 2 is fixedly connected to the base 1 and is used for transmission connection with the drive device 301 of the food processing equipment, so that the attachment device AM can be driven by the drive device 301 to rotate relative to the evaporator 401. The second connecting part 3 is fixedly connected to the base 1 and is used to support the main unit MB of the food processing equipment. In this way, not only can the corresponding structure of the attachment device AM and the main unit MB be assembled together with a relatively simple structure, but the attachment device AM can also be stably supported by the main unit MB of the food processing equipment through these two connecting parts 2 and 3, thereby ensuring the stability of the attachment device AM during rotation. The drive device 301 of the main unit MB can stably drive the attachment device AM to rotate around the rotation axis (that is, the central axis of the main body 11) defined by the transmission rod 31 and the transmission hole 21h.

[0135] like Figures 1A to 1D as well as Figure 4A and Figure 4B As shown, the first connecting portion 2 may include a first body portion 21 into which a first mounting hole 11h1 is inserted into the main body portion 11. A transmission hole 21h may be formed in the first body portion 21, and the transmission hole 21h may be configured such that at least a portion thereof has a non-circular cross-sectional shape. By fitting the non-circular portion of the transmission hole 21h with the shape of the output shaft 3012 of the drive device 301, a direct transmission connection between the first connecting portion 2 and the output shaft 3012 is achieved. This transmission connection scheme is simple, reliable, and easy to implement. Figures 1A to 1D as well as Figure 4C and Figure 4D As shown, the second connecting part 3 may further include an operating part 32, a connecting rod part 33, and a second body part 34. The operating part 32, the connecting rod part 33, and the second body part 34 can be integrally formed with the transmission rod part 31 and fixed together. The operating part 32 can be directly connected to the transmission rod part 31, and the operating part 32 can protrude radially outward relative to the transmission rod part 31, thereby forming a protruding flange structure. The connecting rod part 33 can be directly connected to the operating part 32, and the connecting rod part 33 and the transmission rod part 31 can extend from the operating part 32 toward opposite sides in the axial direction D1. The operating part 32 can protrude radially outward relative to the connecting rod part 33, thereby forming a protruding flange structure. In this way, by providing the connecting rod part 33, sufficient operating space can be provided for the user to manually operate the operating part 32. Thus, the user can hold the operating part 32 to install the attachment device AM onto the main unit MB of the food processing equipment and remove the attachment device AM from the main unit MB.

[0136] By adopting the above-described scheme, after the attachment device AM for the food processing equipment according to the first embodiment of this disclosure is installed on the main unit MB of the food processing equipment and in place, the attachment device AM can be connected to the drive device 301 of the food processing equipment for transmission. Thus, the attachment device AM can be in a stationary state, with the liquid in the chamber 1c being cooled (especially frozen) by the outer evaporator 401; or the attachment device AM can be driven by the drive device 301 to rotate while the liquid in the chamber 1c is cooled by the outer evaporator 401. This not only improves the flexibility of the cooling method of the attachment device AM, but also significantly improves the cooling efficiency (especially the freezing efficiency) of the food processing equipment including the attachment device AM, thereby reducing the time required to cool or even freeze the liquid in the chamber 1c. Furthermore, while the attachment device AM is driven to rotate, during the process of the liquid in chamber 1c being cooled by the evaporator 401, the air bubbles in the liquid (e.g., pure water) in chamber 1c do not disperse within the liquid, but move toward the outside of the liquid. This is beneficial for forming frozen products (e.g., ice cubes) with high transparency that have no air bubbles or contain fewer air bubbles.

[0137] In some other non-limiting embodiments of this disclosure, the structure of the attachment device AM for food processing equipment is partially the same as that of the attachment device AM for food processing equipment described above. The main differences between them are described below.

[0138] In some non-limiting embodiments of this disclosure, such as Figures 5A to 5CAs shown, the base 1 includes a plurality of separate parts 13 (e.g., three separate parts 13 shown in the figure) that can be detachably assembled together. Specifically, the base 1 can be divided into multiple parts along its axial direction D1. This disclosure does not limit the number of separate parts 13; for example, it may include only two separate parts 13 or more than three separate parts 13. A chamber 1c may be defined between every two adjacent separate parts 13, such that the base 1 defines a desired number of chambers 1c between these separate parts 13. Further, each separate part 13 forms recesses facing each other. Specifically, the separate part 13 located at one end along the axial direction may form only one recess, the separate part 13 located at the other end along the axial direction may form only one recess, and the separate part 13 located between these two separate parts 13 may form a recess on each of its two axial sides. Thus, the recesses of every two adjacent separate parts 13 along the axial direction D1 can jointly form a chamber 1c. In the example shown in the figure, chamber 1c can be constructed into a spherical shape. To allow the multiple sub-parts 13 to be detachably assembled together, one of two adjacent sub-parts 13 can be provided with a connector 131, and the other of two adjacent sub-parts 13 can be provided with a connector hole 13h. The connector 131 can be inserted into the connector hole 13h1, thus connecting the two adjacent sub-parts 13 to each other. The connectors 131 provided on a sub-part 13 can be evenly distributed at intervals along the circumferential direction D3, and correspondingly, the connector holes 13h provided on a sub-part 13 can also be evenly distributed at intervals along the circumferential direction D3.

[0139] In addition, such as Figures 5A to 5C As shown, the first connecting part 2 can be integrally formed and fixedly connected to the split part 13 located at one end of the base 1 via integral molding, that is, the first body part 21 of the first connecting part 2 is integrally formed with the split part 13. The second connecting part 3 can be integrally formed and fixedly connected to the split part 13 located at the other end of the base 1 via integral molding, that is, the second body part 34 of the second connecting part 3 is integrally formed with the split part 13.

[0140] By adopting the above technical solution, an optional structural scheme for the substrate 1 can be provided to form the chamber 1c through a relatively simple structure. Moreover, a sufficient number of chambers 1c can be formed by increasing the number of the split parts 13, and the specific shape of the chamber 1c can also be flexibly adjusted by the shape of the recessed portion of the split part 13.

[0141] The following description, in conjunction with the accompanying drawings, describes a food processing apparatus according to a non-limiting embodiment of the present disclosure.

[0142] like Figures 6A to 6CAs shown, a food processing apparatus according to some non-limiting embodiments of this disclosure may include a main unit MB and an attachment device AM for food processing apparatus as described above. The attachment device AM may be detachably mounted to the main unit MB. The food processing apparatus may be a soft-serve ice cream machine or a smoothie machine, or other types of equipment. In some non-limiting embodiments of this disclosure, such as... Figures 6A to 6C As shown, the main unit MB may include a housing assembly 10, a cooling cylinder assembly 20, a stirring assembly 30, and a cooling system 40 assembled together.

[0143] In some non-limiting embodiments of this disclosure, such as Figures 6A to 6C As shown, the housing assembly 10 is used to support and protect the cooling cylinder assembly 20, the stirring assembly 30, and the cooling system 40. Specifically, the housing assembly 10 may include different parts that can be detachably assembled together, and these parts may constitute the upper housing portion and the lower housing portion of the housing assembly 10.

[0144] In some non-limiting embodiments of this disclosure, such as Figures 6A to 6C and Figure 7A As shown, the front cover assembly 101 can be installed not only at the front end of the housing assembly 10, but also at the front end of the cooling cylinder assembly 20 to close the front opening of the cooling cylinder assembly 20, so that the front cover assembly 101 and the cooling cylinder assembly 20 together enclose and form an internal space. The front cover assembly 101 may include a dispensing component for dispensing food within the aforementioned space, and the front cover assembly 101 may also include a support hole 101h for supporting the second connecting portion 3 of the attachment device AM, the support hole 101h being open towards the aforementioned internal space. Thus, when the attachment device AM is installed in the aforementioned internal space, the transmission rod portion 31 of the second connecting portion 3 can be inserted into the support hole 101h and supported by the front cover assembly 101.

[0145] In some non-limiting embodiments of this disclosure, such as Figures 6A to 6C and Figure 7BAs shown, the cooling cylinder assembly 20 may include a cooling cylinder 201, an outer cover 202, and a rear cover assembly 203 assembled together. The cooling cylinder assembly 20 can be used to collect food to be processed and can be used to agitate the food using a stirrer 302 installed on the cooling cylinder assembly 20. The cooling cylinder 201 and the outer cover 202 can be assembled together. The outer cover 202 can be configured to have a shape and structure that can accommodate the cooling cylinder 201, and the inner wall of the outer cover 202 can define a space between it and the outer wall of the cooling cylinder 201 for mounting the evaporator 401 of the cooling system 40. The rear cover assembly 203 can be assembled with the cooling cylinder 201 and the outer cover 202. The rear cover assembly 203 can be used to mount and support the stirring motor assembly 3011 of the drive device 301. The rear cover assembly 203 may also have a central through hole through which the output shaft 3012 of the drive device 301 is inserted.

[0146] In some non-limiting embodiments of this disclosure, such as Figure 6C and Figure 7C As shown, the stirring assembly 30 can be installed on the cooling cylinder assembly 20 and the front cover assembly 101 for stirring the food inside the cooling cylinder 201. Specifically, the stirring assembly 30 may include a drive unit 301 and a stirrer 302 assembled together. The drive unit 301 may include a stirring motor assembly 3011 and an output shaft 3012 that are drive-coupled. The stirring motor assembly 3011 can be installed on the rear cover assembly 203, and the output shaft 3012 extends linearly through the rear cover assembly 203 along the front-rear direction of the main unit MB. Figure 7C As shown, the stirring motor assembly 3011 can be a functional module with a motor and a gearbox. The motor can transmit sufficient torque to the output shaft 3012 via the gearbox, thereby driving the stirrer 302 to stir the food. The gearbox can be a geared gearbox, belt-driven gearbox, or other types of gearbox. The stirrer 302 can be positioned inside the cooling cylinder 201. Figure 6C As shown, the stirrer 302 can be installed in the support hole 101h of the front cover assembly 101 and through the output shaft 3012 of the rear cover assembly 203, so that the output shaft 3012 can transmit the torque of the stirring motor assembly 3011 to the stirrer 302, so that the stirrer 302 can rotate freely relative to the cooling cylinder 201.

[0147] In some non-limiting embodiments of this disclosure, such as Figure 6CAs shown, the operation of the cooling system 40 can be controlled by a controller. The refrigerant in the cooling system 40 can circulate within the cooling system 40, thereby cooling the food inside the cooling cylinder 201 when the refrigerant flows through the vicinity of the cooling cylinder 201. Specifically, the cooling system 40 may include an evaporator 401, a compressor 402, a condenser 403, and a throttle valve 404 that are interconnected. Conduits can be connected between the components of the cooling system 40 in a closed loop. The evaporator 401 includes a cooling spiral tube made of a material with good thermal conductivity, such as copper. The cooling spiral tube of the evaporator 401 can be configured to extend continuously in a spiral manner and can be integrally fitted onto the outside of the cooling cylinder 201. In this way, the refrigerant flowing in the evaporator 401 can fully exchange heat with the food inside the cooling cylinder 201, thereby cooling the food. The compressor 402 can be fixedly mounted on the housing assembly 10, and the compressor 402 can be used to compress the refrigerant flowing through it. The condenser 403 can be fixedly installed on the housing assembly 10 and can be used to condense the gaseous refrigerant flowing through it. In addition, the throttle valve 404 can also be installed on the housing assembly 10 and can control the flow rate of the refrigerant flowing through it.

[0148] By adopting the above-described scheme, the food processing equipment according to this disclosure can operate in at least two modes of use. In the first mode of use, such as... Figure 6C As shown, the stirrer 302 can be installed in the cooling cylinder assembly 20. Thus, while the stirrer 302 stirs the food in the cooling cylinder 201, the evaporator 401 cools the food. In the second usage mode, as... Figure 7DAs shown, the attachment device AM can replace the stirrer 302 when installed in the cooling cylinder assembly 20, or the attachment device AM can replace both the stirrer 302 and the cooling cylinder assembly 20. In this way, the attachment device AM can be positioned inside the evaporator 401, and the two connecting parts 2 and 3 of the attachment device AM can be supported by the front cover assembly 101 and the rear cover assembly 203, respectively. Furthermore, the attachment device AM can be connected to the drive device 301 for transmission. Therefore, the attachment device AM can be in a stationary state, allowing the liquid in the chamber 1c to be cooled (especially frozen) by the outer evaporator 401; or the attachment device AM can be driven by the drive device 301 to rotate, allowing the liquid in the chamber 1c to be cooled by the evaporator 401. This not only improves the flexibility of the cooling method of the attachment device AM but also significantly improves the cooling efficiency (especially the freezing efficiency) of the food processing equipment including the attachment device AM, thereby reducing the time required to cool or even freeze the liquid in the chamber 1c. Furthermore, while the attachment device AM is driven to rotate, during the process of the liquid in chamber 1c being cooled by the evaporator 401, the air bubbles in the liquid (e.g., pure water) in chamber 1c do not disperse within the liquid, but move toward the outside of the liquid. This is beneficial for forming frozen products (e.g., ice cubes) with high transparency that have no air bubbles or contain fewer air bubbles.

[0149] It should be understood that the above embodiments are merely exemplary and are not intended to limit the scope of protection of this disclosure. Those skilled in the art can make various modifications and changes to the above embodiments under the teachings of this disclosure without departing from the scope of this disclosure. The following supplementary descriptions are provided regarding the technical solutions of this disclosure.

[0150] i. In some non-limiting embodiments of this disclosure, the substrate 1 of the attachment device AM can have different structures to form different shapes and numbers of chambers 1c. However, this disclosure does not limit the specific construction of the substrate 1, as long as the substrate 1 can form the desired shape and desired number of chambers 1c. For example, the shape of the chambers 1c can be constructed as spherical, elongated with arbitrary cross-sectional shape, and various other shapes, thereby enabling the production of frozen products of various shapes.

[0151] ii. In some non-limiting embodiments of this disclosure, during the cooling process while the attachment device AM is rotating, in order to balance cooling efficiency and other aspects such as noise, the inventors of this disclosure have studied and found that the rotation speed of the attachment device AM in the food processing equipment can be controlled within a predetermined range, for example, it can be controlled between 2 revolutions per minute and 3 revolutions per minute.

[0152] iii. In some non-limiting embodiments of this disclosure, patterns or ribs protruding toward the cavity 1c may be provided on the inner wall of the receiving cylinder 121 to increase the contact area between the receiving cylinder 121 and the liquid, thereby further improving the cooling efficiency.

[0153] iv. In some non-limiting embodiments of this disclosure, the base 1 may be provided with a snap-fit ​​structure to more securely connect the storage component 12 and the main body 11 to each other, thereby preventing the storage component 12 from detaching from the main body 11 during the rotation of the attachment device AM.

[0154] v. To form a bubble-free or low-bubble-containing frozen product (e.g., ice) within chamber 1c, the liquid added to chamber 1c, such as water, can be filtered or otherwise pretreated. Furthermore, the freezing rate also plays a role in forming a bubble-free or low-bubble-containing frozen product. This freezing rate can be adjusted by controlling the temperature within chamber 1c and the rotational speed of the attachment device AM. For example, the temperature within chamber 1c can be controlled, for example, between -1°C and -5°C, and the rotational speed of the attachment device AM can be controlled, for example, between 2 and 3 revolutions per minute. Furthermore, having a smooth surface on the inner wall of chamber 1c is beneficial for forming a bubble-free or low-bubble-containing frozen product. Furthermore, a larger volume of chamber 1c is also beneficial for forming a bubble-free or low-bubble-containing frozen product.

[0155] vi. In some non-limiting embodiments of this disclosure, the food processing equipment may be a smoothie machine or a soft-serve ice cream machine, but this disclosure is not limited thereto. The food processing equipment may also be other types of food processing equipment. As used herein, "food processing equipment" is not limited to producing only frozen foods, but may be used to produce chilled beverage products to produce any of a variety of frozen and semi-frozen forms of food. Such foods typically consist of a mixture of water or milk, syrups, flavoring powders, or other additives or fillers that impart the desired flavor and color to the food. For example, the food processing equipment may produce, for example, ice cream, gelato, sorbet, milkshakes, slushies, granitas, and / or other types of frozen or semi-frozen beverages, or suitable combinations of any of the types described above.

[0156] The components of the different embodiments described can be combined to form other embodiments not previously described. Components can be omitted from the previously described system without adversely affecting its operation or the operation of the system as a whole. Furthermore, various individual components can be combined into one or more individual components to perform the functions described in this specification.
