[0029] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings.

[0030] like Figures 1 to 12 An ice maker with a cold water reflux assembly is shown, comprising a casing 1, the casing 1 being provided with a casing inner cavity 11, the casing 1 being provided with an ice-making module 2, a water tank 3 located below the casing inner cavity 11, and a cold water reflux assembly located between the ice-making module 2 and the water tank 3, the ice-making module 2 including an ice-discharging assembly 4 for discharging ice cubes, the ice-discharging assembly 4 being provided with an ice-discharging outlet 49, an ice-discharging channel 41 partially or completely extending to the outside of the casing inner cavity 11, and a drain port 42 located on the ice-discharging channel 41, the cold water reflux assembly being provided with a first collecting end 5 located between the drain port 42 and the casing inner cavity 11, and a first discharge end 6 respectively connected to the casing inner cavity 11 and the water tank 3.

[0031] The melted water of the utility model is collected and returned to the water tank, which can be reused by the ice maker, reducing the waste of water resources. The user does not need to manually empty the accumulated water frequently, thereby reducing the number of cleaning and maintenance. When the ice making module completes ice making, the ice cubes are discharged through the ice outlet channel and the ice discharge outlet of the ice outlet assembly. During the ice discharge process, the cold water generated by the melted ice cubes flows into the first collecting end of the cold water return assembly through the drain port, and then the cold water flows back to the water tank through the first discharge end of the cold water return assembly to be used for ice making next time.

[0032] Specifically, the ice making module is used for cooling water and making ice cubes and discharging the ice cubes through the ice discharging assembly. The ice discharging channel partially or entirely extends outside the inner cavity of the machine shell, facilitating the user to take the ice. The water tank is located at the lower side of the inner cavity of the machine shell and is used for storing water required for ice making. When the ice making module makes ice, the water in the water tank can be transported into the ice making module. The first collecting end is used for collecting the cold water of the ice cubes moving to the drain port. After the cold water of the first collecting end is transferred to the inner cavity of the machine shell, the cold water is returned to the water tank from the inner cavity of the machine shell through the first discharging end.

[0033] Optionally, in some embodiments, the ice discharging assembly is provided with an ice discharging assembly shell 40, and the ice discharging assembly shell is provided with an ice discharging assembly shell inner cavity 401 capable of partially or entirely enclosing the ice discharging channel, thereby reducing the air entering the ice discharging assembly.

[0034] Optionally, in some embodiments, the ice discharging assembly shell is separately arranged outside the machine shell, facilitating the modular assembly. At this time, the ice discharging assembly is partially located in the inner cavity of the machine shell.

[0035] Optionally, in some embodiments, the ice discharging assembly shell and the machine shell are arranged in a close connection mode such as integral molding, fastener connection, welding, etc., and the inner cavity of the machine shell and the inner cavity of the ice discharging assembly shell can be in close communication. At this time, the ice discharging assembly is entirely located in the inner cavities of the machine shell and the ice discharging assembly shell.

[0036] As shown in a kind of ice maker with cold water return assembly, Figures 2 to 6 The ice discharging channel 41 includes an inclined guide portion 411, a connecting bottom plate 412 connected to the guide portion 411, and a water storage cavity 413 formed by the guide portion 411 and the connecting bottom plate 412. The guide portion 411 is provided with a drainage port 4111 communicating with the water storage cavity 413. The drain port 42 is located on the connecting bottom plate 412.

[0037] Further, as a preferred embodiment of the present application, the inclined guide portion can guide the ice cubes to slide out smoothly. During the sliding process of the ice cubes, due to the friction between the ice cubes and the guide portion or the melting of the ice cubes themselves, the cold water generated will flow into the water storage cavity through the drainage port, reducing the residence time of the ice cube melting water in the ice discharging channel and the risk of bacterial growth caused by accumulated water.

[0038] Specifically, the water storage cavity can temporarily store these cold waters, avoiding direct dripping into the inner cavity of the machine shell or directly dripping into the ice discharging outlet, reducing the possibility of contamination. The drain port is located on the connecting bottom plate, so that the cold water in the water storage cavity can be smoothly discharged from the lower side of the connecting bottom plate into the cold water return assembly, achieving automatic drainage and collection.

[0039] Optionally, in some embodiments, the connecting bottom plate is inclined from top to bottom, the lowest point is located at the end of the connecting bottom plate close to the side of the cabinet, and the water outlet is located at the end of the connecting bottom plate close to the side of the cabinet, so that water can move to the first collection end direction to the maximum extent.

[0040] As shown in the ice maker with a cold water return assembly, the ice outlet channel 41 comprises an inclined guide portion 411, a connecting bottom plate 412 connected with the guide portion 411, and a water storage cavity 413 formed by the guide portion 411 and the connecting bottom plate 412, the water outlet 42 is located at the guide portion 411, and the first collection end 5 is located on the cabinet 1 and close to the connecting bottom plate 412. Figure 7

[0041] Further, as a preferred embodiment of the utility model but not limited, the inclined guide portion can guide the ice cubes to slide out smoothly, and during the ice cube sliding process, the cold water generated due to the friction between the ice cubes and the guide portion or the melting of the ice cubes can flow into the water storage cavity along the water outlet, thereby reducing the residence time of the ice cube melting water in the ice outlet channel and reducing the risk of water accumulation and bacteria breeding. The connecting bottom plate can support the accumulated water, so that the water can move to the first collection end direction on the cabinet.

[0042] Optionally, in some embodiments, the connecting bottom plate is inclined from top to bottom, the lowest point is located at the end of the connecting bottom plate close to the side of the cabinet, and the first collection end is located at the bottom of the cabinet close to the connecting bottom plate, so that water can move to the inner cavity of the cabinet direction to the maximum extent.

[0043] As shown in the ice maker with a cold water return assembly, the ice outlet channel 41 comprises an inclined guide portion 411, a connecting bottom plate 412 connected with the guide portion 411, and a water storage cavity 413 formed by the guide portion 411 and the connecting bottom plate 412, the water outlet 42 is located at the guide portion 411, and the first collection end 5 is located on the cabinet 1 and close to the connecting bottom plate 412. Figures 2 to 12 Further, as a preferred embodiment of the utility model but not limited, through the driving device, the ice cubes at the bottom of the ice outlet assembly can be effectively moved to the ice outlet channel without manual intervention, thereby improving the automation degree of the ice maker. The first collection end is located between the water outlet and the first discharge end, which ensures that the melting water can be collected in time during the ice cube transfer process, thereby reducing the residence time of the water in the ice outlet assembly and reducing the risk of water accumulation and bacteria breeding. Compared with the prior art, the ice maker does not need to set a water storage box and wait until the water is full before being taken out for cleaning.

[0044]

[0045] ​​Specifically, the first discharge port is located at or below the drive assembly, allowing the collected meltwater to flow smoothly back into the water tank. This prevents excessive contact and interference between the water and the movement of the drive assembly during the transfer process, ensuring smooth water flow and improving drainage and return efficiency.

[0046] like Figures 2 to 12 The ice maker shown has a cold water return assembly, wherein the drive assembly 43 is provided with a mounting shell 432 located within the casing 1, the mounting shell 432 is provided with a first mounting cavity 4321 for accommodating the drive device 431, and the first discharge end 6 is located at the bottom of the mounting shell 432 or at the lower side of the mounting shell 432.

[0047] Furthermore, as a preferred embodiment of the present invention, but not a limitation, the provision of the mounting housing enables the drive assembly to be compactly mounted within the housing, reducing space requirements. Furthermore, the first mounting cavity provides stable support and protection for the drive assembly, helping to reduce noise and vibration, and improving the reliability and durability of the drive assembly. The first discharge port, located at the bottom or underside of the mounting housing, allows meltwater to drain directly and smoothly into the water tank, reducing obstruction to water flow and the risk of water accumulation, thereby improving drainage efficiency.

[0048] like Figures 2 to 12 An ice maker with a cold water reflux assembly is shown, wherein the driving device 431 includes a rotating disk 4311 located in the first installation cavity 4321 and a driving member 4312 for driving the rotating disk 4311 to rotate. The rotating disk 4311 is provided with a receiving cavity 43111 that is connected to the ice outlet channel 41 and is used to receive ice cubes. A reflux water gap 431111 is provided between the receiving cavity 43111 and the inner side of the casing 1. The reflux water gap 431111 is connected to the first discharge end 6. The bottom of the first installation cavity 4321 is provided with an installation cavity drain outlet 43211 that is connected to the first discharge end 6.

[0049] Furthermore, as a preferred embodiment of the present invention but not a limitation, the rotating disk is arranged in the vertical direction and rotates along the horizontal axis. The first installation cavity can prevent the misalignment and deviation of the rotating disk during operation, and the ice cubes are transferred by means of height difference. The driving member drives the rotating disk to rotate, and multiple accommodating cavities are used to accommodate the ice cubes, thereby realizing the orderly transportation of the ice cubes from the bottom of the ice outlet assembly to the ice outlet channel. Without the need for manual intervention, the movement of the ice cubes can be precisely controlled to avoid accumulation or jamming of the ice cubes during transportation, thereby ensuring that the ice cubes can be continuously and stably supplied to the ice outlet channel, meeting the user's requirements for the continuity of ice output.

[0050] Specifically, the return water gap allows meltwater to flow out of the storage chamber during ice movement and into the first discharge port through the return water gap. This reduces the time water remains in the rotating disk and storage chamber, reducing the risk of water accumulation and bacterial growth. The installation chamber drain port is located at the bottom of the first installation chamber and connected to the first discharge port, preventing water from accumulating within the installation housing and ensuring that meltwater can be discharged directly and smoothly into the water tank, thereby improving drainage efficiency and reducing water waste. This also prevents water from the first collection port from entering the inner cavity of the housing and then the first installation chamber, where it remains within the installation housing.

[0051] like Figure 3 、 Figure 6 and Figure 11 An ice maker with a cold water reflux assembly is shown, wherein the cold water reflux assembly includes a collecting shell 7 connected to the outside of the casing 1, the collecting shell 7 is provided with a collecting trough 71 and a collecting trough opening 72 located on the collecting trough 71, and the bottom of the collecting trough 71 is connected to the first collecting end 5.

[0052] Furthermore, as a preferred embodiment of the present invention but not limiting, the collection trough can efficiently collect meltwater flowing out of the drain outlet. Through the collection trough opening, the meltwater can flow smoothly into the collection trough, avoiding splashing and dripping of water, thereby reducing water waste and external pollution.

[0053] Optionally, in some embodiments, such a setting allows water to move a distance downward from the drain outlet and then enter the first drain end from the inner cavity of the casing. By shortening the distance between the first collection end and the first discharge end, splashing of water caused by water moving directly downward from a high point in the inner cavity of the casing is avoided.

[0054] like Figure 3 、 Figure 6 and Figure 11 An ice maker with a cold water reflux assembly is shown, wherein the collection shell 7 includes an inner collection shell 73 close to the casing 1, and an outer collection shell 74 connected to the outside of the inner collection shell 73. The inner collection shell 73 and the outer collection shell 74 enclose the collection trough 71. The collection shell 7 is V-shaped or U-shaped, and the collection trough opening 72 is located on the lower side of the drain outlet 42.

[0055] Furthermore, as a preferred embodiment of the present invention rather than a limitation, the arrangement of the collection tank and the collection tank opening facilitates cleaning and maintenance by the user. The user can easily disassemble the collection shell and clean the accumulated water and impurities in the collection tank, thereby ensuring the smooth operation of the cold water return component and extending its service life.

[0056] Furthermore, as a preferred embodiment of the present invention but not a limitation, the V-shaped or U-shaped collection shell design can guide the water flow to flow smoothly into the bottom of the collection tank, reducing the splashing and dripping of the water flow, thereby improving the collection efficiency.

[0057] Optionally, in some embodiments, the inner collection shell extends outward from the casing, and the outer collection shell is connected to the outside of the inner collection shell by snapping, fasteners, magnetism, mortise and tenon, and groove connection. When the user cleans the collection shell, he only needs to disassemble the outer collection shell.

[0058] like Figures 2 to 11 An ice maker with a cold water reflux assembly is shown, wherein the ice-making module 2 further includes an ice-making assembly 8 located in the inner cavity 11 of the casing, the ice-making assembly 8 including an ice-making mold 81, a water supply tank 82 for supplying water to the ice-making mold 81, a refrigeration component 83 connected to the ice-making mold 81, and a water inlet channel 84 connected to the water tank 3 and extending into the water supply tank 82. The cold water reflux assembly includes a bottom plate 9 located in the inner cavity 11 of the casing, one end of the bottom plate 9 is connected to the water tank 3, and the bottom plate 9 is provided with a first pipe opening 91 for the water inlet channel 84 to pass through, and a first water retaining portion 92 extending upward from the first pipe opening 91.

[0059] Furthermore, as a preferred embodiment of the present invention but not a limitation, the ice-making assembly includes an ice-making mold, a water supply tank, a refrigeration component, and a water inlet channel. The coordinated operation of these components realizes the complete process from water supply to ice making. Ice cubes can be efficiently produced by supplying water to the ice-making mold and cooling it through the refrigeration component. When the connection between the water inlet channel and the water supply tank is not tight enough, water will seep out from the connection between the water inlet channel and the water supply tank. The setting of the bottom plate allows the seeped water to flow back to the water tank. The upwardly extending first water retaining portion can prevent the water from moving toward the first pipe opening, causing the water to move along the bottom plate toward the water tank, preventing the water from flowing directly from the first pipe opening to the inner cavity of the casing or from the first pipe opening to the outside of the casing, thereby realizing the reuse of water resources and improving the water-saving performance of the ice maker by reducing the waste of water resources.

[0060] Optionally, in some embodiments, the bottom plate may be tilted to allow water to move quickly toward the water tank.

[0061] like Figure 9 The ice maker shown has a cold water reflux assembly, wherein the bottom plate 9 is provided with a second pipe opening 93 for part of the refrigeration component 83 to pass through, and a second water retaining portion 94 extending upward from the second pipe opening 93. The second water retaining portion 94 is provided with a cover body 941 for part of the refrigeration component 83 to pass through and covering the second pipe opening 93.

[0062] Furthermore, as a preferred embodiment of the present invention, but not limiting, the provision of the second water retaining portion and the cover effectively prevents water from directly contacting the refrigeration components, thereby preventing damage or performance degradation to the refrigeration components caused by water contact, thereby helping to extend the service life of the refrigeration components and improving the overall reliability of the ice maker. The second water retaining portion and the cover can prevent excessive external moisture and air from entering the inner cavity of the casing through the second pipe opening.

[0063] Specifically, during the refrigeration process, the refrigeration component may easily cause water droplets to form around the ice-making assembly, or when the water inlet channel and the water supply tank are not tightly connected, water will seep out from the connection between the water inlet channel and the water supply tank. In order to prevent water from flowing out of the second pipe opening to the inner cavity of the casing or from flowing out of the second pipe opening to the outside of the casing, the upwardly extending second water retaining portion can prevent water from moving toward the second pipe opening, so that water moves along the bottom plate toward the water tank.

[0064] Example 1

[0065] like Figures 2 to 6 An ice maker with a cold water reflux assembly is shown, comprising a casing 1, the casing 1 being provided with a casing inner cavity 11, the casing 1 being provided with an ice-making module 2, a water tank 3 located below the casing inner cavity 11, and a cold water reflux assembly located between the ice-making module 2 and the water tank 3, the ice-making module 2 including an ice-discharging assembly 4 for discharging ice cubes, the ice-discharging assembly 4 being provided with an ice-discharging outlet 49, an ice-discharging channel 41 partially or completely extending to the outside of the casing inner cavity 11, and a drain port 42 located on the ice-discharging channel 41, the cold water reflux assembly being provided with a first collecting end 5 located between the drain port 42 and the casing inner cavity 11, and a first discharge end 6 respectively connected to the casing inner cavity 11 and the water tank 3.

[0066] The melted water of the present invention is collected and returned to the water tank 3, and can be reused by the ice maker, reducing the waste of water resources. The user does not need to manually empty the accumulated water frequently, thereby reducing the number of cleaning and maintenance. When the ice making module 2 completes ice making, the ice cubes are discharged through the ice outlet channel 41 and the ice discharge outlet 49 of the ice outlet assembly 4. During the ice discharge process, the cold water generated by the melting of the ice cubes flows into the first collecting end 5 of the cold water return assembly through the drain port 42. Subsequently, the cold water flows back to the water tank 3 through the first discharge end 6 of the cold water return assembly to be used for the next ice making.

[0067] Example 2

[0068] Based on implementation 1, embodiment 2 has the following implementation method: the ice-discharging component 4 is provided with an ice-discharging component housing 40, and the ice-discharging component housing 40 is provided with an ice-discharging component housing inner cavity 401. The ice-discharging component housing inner cavity 401 can partially or completely enclose the ice-discharging channel 41 to reduce the entry of air into the ice-discharging component 4.

[0069] The ice discharging assembly housing 40 is separately arranged outside the housing 1 to facilitate modular assembly. At this time, the ice discharging assembly 4 is partially located in the housing cavity 11.

[0070] Example 3

[0071] The difference between Example 3 and Example 2 is that the ice dispensing assembly housing 40 and the housing 1 are integrally connected, and the housing cavity 11 and the ice dispensing assembly housing cavity 401 are closely connected. In this case, the ice dispensing assembly 4 is completely located within the housing 11 and the ice dispensing assembly housing 40.

[0072] Example 4

[0073] Example 4, based on Example 1, has the following implementation: the ice outlet channel 41 includes an inclined guide portion 411, a connecting base plate 412 connected to the guide portion 411, and a water storage cavity 413 enclosed by the guide portion 411 and the connecting base plate 412. The guide portion 411 is provided with a drainage port 4111 communicating with the water storage cavity 413, and the drain port 42 is located on the connecting base plate 412. Cold water in the water storage cavity 413 can be discharged from the underside of the connecting base plate 412 and enter the cold water return assembly, achieving automatic drainage and collection.

[0074] Example 5

[0075] like Figure 7 As shown, Example 5, based on Example 1, further has the following implementation: the ice outlet channel 41 includes an inclined guide portion 411, a connecting bottom plate 412 connected to the guide portion 411, and a water storage cavity 413 formed by the guide portion 411 and the connecting bottom plate 412; the drain port 42 is located on the guide portion 411; and the first collecting end 5 is located on the casing 1 and close to the connecting bottom plate 412.

[0076] Due to the friction between the ice and the guide part 411 or the melting of the ice itself, the cold water generated will flow into the water storage cavity 413 along the drain port 42. The connecting bottom plate 412 can support the accumulated water, allowing the water to move toward the first collecting end 5 on the housing 1.

[0077] Example 6

[0078] Example 6 is based on example 4, and further has the following implementation: the ice discharging assembly 4 is provided with a driving assembly 43 located between the water outlet 42 and the first discharging end 6, the driving assembly 43 is provided with a driving device 431 for driving the ice blocks located at the bottom of the ice discharging assembly 4 to move to the ice discharging channel 41, the first collecting end 5 is located on the cabinet 1 and between the water outlet 42 and the first discharging end 6, and the first discharging end 6 is located at the driving assembly 43.

[0079] The driving assembly 43 is provided with a mounting shell 432 located in the cabinet 1, the mounting shell 432 is provided with a first mounting cavity 4321 accommodating the driving device 431, and the first discharging end 6 is located at the bottom of the mounting shell 432.

[0080] Example 7
