SUMMARY

[0004] The technical problem to be solved by the utility model is to provide a leakproof structure of ice maker, which is beneficial to reduce backflow.

[0005] The technical solution of the utility model is a leakproof structure of ice maker, which comprises an ice making cylinder, a stirring assembly and a rotating shaft, the rotating shaft is provided with the stirring assembly to form a first assembly, a gear box is located on one side of the ice making cylinder, the first assembly is axially inserted into the ice making cylinder from the other side of the ice making cylinder, and the leakproof structure further comprises an output shaft, the output shaft is installed on the gear box, an output gear of the gear box is sleeved on the output shaft, the output shaft is provided with an axial through hole, the upper end of the axial through hole is communicated with the lower end of the ice making cylinder, and the lower end of the axial through hole is used for being communicated with the outside, when the first assembly is axially inserted into the ice making cylinder from the other side of the ice making cylinder, the end of the rotating shaft located on the side of the gear box is detachably connected with the axial through hole in transmission cooperation, the output gear drives the output shaft to drive the rotating shaft to rotate, and the rotating shaft drives the stirring assembly to rotate relative to the ice making cylinder.

[0006] The lower end of the output shaft penetrates through the matching hole of the shell of the gear box to be protruding, the output shaft is rotatably connected with the matching hole, and a connecting part is arranged at the matching hole of the gear box, the connecting part is rotatably and sealingly connected with the output shaft, the connecting part is further provided with a drain pipe or is used for connecting the drain pipe, and the drain pipe is communicated with the axial through hole.

[0007] When cleaning is needed, the first assembly is axially pulled out of the ice making cylinder from the other side of the ice making cylinder, and the sewage generated during the cleaning of the ice making cylinder can flow out from the axial through hole and the drain pipe.

[0008] After the above structure is adopted, the utility model has the following advantages:

[0009] The present disclosure solves the technical problem that the drain pipe is not directly connected to the rotating output shaft by improving the structure, i.e., the connecting part is rotatably connected to the output shaft, and the connecting part is provided with a drain pipe or a connecting part for connecting the drain pipe, which is in communication with the axial through hole. Thus, the technical problem of realizing the communication between the drain pipe and the axial through hole in the rotating connection is avoided, and the technical problem of backflow into the gear box through the matching hole is avoided under the effect of the rotatable matching of the sealing sleeve.

[0010] In addition, while solving the rotating problem of the stirring assembly and the above two technical problems, a new cleaning scheme is proposed. Specifically, when cleaning is needed, the first assembly pulls out the ice making cylinder from the other side of the ice making cylinder. At this time, the axial through hole is no longer blocked by the rotating shaft, so the ice making cylinder is in communication with the axial through hole. Thus, the sewage generated during the cleaning of the ice making cylinder can flow out of the axial through hole. Further, due to the provision of the axial through hole, the ice making cylinder can be cleaned by flushing. Flushing the ice making cylinder can improve the cleaning efficiency and simplify the cleaning operation, which is convenient for users to clean. Although a large amount of cleaning sewage is generated in a short time, the present disclosure can reduce backflow and improve the overall reliability of the ice maker.

DETAILED DESCRIPTION

[0027] In order to better understand the present application, various aspects of the present application will be described in more detail with reference to the accompanying drawings. It should be understood that these detailed descriptions are only descriptions of exemplary embodiments of the present application and do not limit the scope of the present application in any way.

[0028] As Figures 1 to 8As shown, the assembly includes an ice-making cylinder 1, a stirring assembly 2, and a rotating shaft 5. The rotating shaft 5 is configured with the stirring assembly 2 to form a first assembly 6. A gearbox 4 is located on one side of the ice-making cylinder 1, and the first assembly 6 is axially inserted into the ice-making cylinder 1 on the other side. The assembly also includes an output shaft 8, which is mounted on the gearbox 4. An output gear 7 from the gearbox 4 is mounted on the output shaft 8. The output shaft 8 has an axial through hole 11, the upper end of which communicates with the lower end of the ice-making cylinder 1, and the lower end of which is used to open to the outside. When the first assembly 6 is axially inserted into the ice-making cylinder 1 on the other side, the end of the rotating shaft 5 located on the side of the gearbox 4 is detachably connected to the axial through hole 11 for transmission. The output gear 7 drives the output shaft 8 to drive the rotating shaft 5 to rotate, and the rotation of the rotating shaft 5 drives the stirring assembly 2 to rotate relative to the ice-making cylinder 1.

[0029] The lower end of the output shaft 8 protrudes through the mating hole of the housing of the gearbox 4. The output shaft 8 is rotatably engaged with the mating hole. The gearbox 4 also includes a connecting part 16 located at the mating hole. The connecting part 16 is rotatably and sealingly engaged with the output shaft 8. The connecting part 16 is also provided with a drain pipe 15 or for connecting the drain pipe 15. The drain pipe 15 is connected to the axial through hole 11.

[0030] When cleaning is required, the other side of the self-made ice cylinder 1 of the first component 6 is axially pulled out for cleaning, and the wastewater generated from cleaning the ice cylinder 1 can flow out from the axial through hole 11 and the drain pipe 15.

[0031] like Figure 8 As shown, during rinsing, the wastewater flows out of the ice-making cylinder 1 in the direction indicated by the arrow. The washed-down material can be discharged efficiently. Even if the large volume of wastewater causes the drain pipe 15 to be unable to discharge in time and causes backflow, the risk of damaging the gearbox 4 is greatly avoided.

[0032] In this example, as Figure 5 , 7 As shown, the connecting part 16 is configured to connect the drain pipe 15, rather than having the drain pipe 15 built-in. This simplifies the structure of the connecting part 16 and facilitates assembly.

[0033] For easy connection, the connecting part 16 is provided with a connecting end 19, which is used to connect with the drain pipe 15. For example, the drain pipe 15 is sleeved on the connecting end 19 and can be fastened with a clamp, so that the drain pipe 15 is not easy to loosen.

[0034] For ease of connection, the connecting end 19 protrudes from the connecting part 16.

[0035] Of course, other structures are also possible. The connecting end 19 is not protruding, but has an internal thread, and the drain pipe 15 is threadedly connected to the connecting end 19.

[0036] When the connecting end 19 protrudes from the connecting portion 16, it is preferable that the connecting end 19 is coaxially arranged with the axial through hole 11. In this way, sewage discharge does not need to bend, which is beneficial for sewage discharge.

[0037] In some embodiments, such as Figure 6 , 7 As shown, the connecting part 16 is integrally provided with an inner circumferential sealing ring 18, which is tightly sealed to the output shaft 8. This saves on sealing rings and simplifies assembly. For example, the connecting part 16 is made of elastic plastic and is integrally molded from plastic, so the inner circumferential sealing ring 18 is also molded together.

[0038] Of course, other sealing structures are also possible, such as a rotatable sealing sleeve fit between the connecting part 16 and the output shaft 8 through a second sealing ring.

[0039] In some embodiments, such as Figure 5 As shown, the connecting part 16 is an independent part. The connecting part 16 is rotatably and sealingly fitted with the lower end of the output shaft 8 from bottom to top, and is fixed to the housing of the gearbox 4 with fasteners. The fasteners are inserted through the connecting hole 20.

[0040] Furthermore, when the connecting part 16 is sleeved onto the lower end of the output shaft 8 from bottom to top, the inner circumferential sealing ring 18 and the output shaft 8 are tightly sealed together. When it is a second sealing ring, when the connecting part 16 is sleeved onto the lower end of the output shaft 8 from bottom to top, the second sealing ring is sealed between the connecting part 16 and the output shaft 8.

[0041] like Figure 5 , 6 As shown in Figure 8, for ease of installation, the connecting part 16 is provided with an axial hole 17, which is rotatably and sealingly fitted with the lower end of the output shaft 8.

[0042] When the connecting part 16 is an independent part, when the connecting part 16 is sleeved with the lower end of the output shaft 8 from bottom to top, the axial hole 17 and the lower end of the output shaft 8 are rotatably sealed and fitted, which makes the assembly very simple.

[0043] The gearbox 4 is connected to a power source. In this example, a motor 3 is used. The motor 3 drives the gear set inside the gearbox 4 to rotate. The rotation of the gear set drives the output gear 7 to rotate. The output gear 7 drives the output shaft 8 to drive the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 drives the stirring assembly 2 to rotate relative to the ice maker 1.

[0044] In some embodiments, such as Figure 6As shown, a first sealing ring 12 is provided between the rotating shaft 5 and the ice-making cylinder 1. When the first component 6 is axially inserted into the ice-making cylinder 1 on the other side, a seal is formed between the outer circumference of the rotating shaft 5, the inner circumference of the first sealing ring 12, the outer circumference of the first sealing ring 12, and the inner circumference of the lower end of the ice-making cylinder 1 along the radial direction from the inside to the outside. In this way, the structure is relatively simple and convenient for production and assembly, thereby achieving the purpose of reducing or avoiding leakage of the object being cooled inside the ice-making cylinder 1 through gaps during normal operation. Such gaps are, for example, the detachable insertion transmission fit gap between the rotating shaft 5 and the axial through hole 11.

[0045] Of course, other sealing structures are also possible. For example, the fit between the rotating shaft 5 and the axial through hole 11 can be made more precise to achieve a certain degree of sealing. Another example is to set a first sealing ring between the rotating shaft 5 and the axial through hole 11 to achieve a sealing fit. In short, any sealing structure applicable to this disclosure can be applied to this disclosure.

[0046] Specifically, the first sealing ring 12 is mounted on the rotating shaft 5 and is pulled out / inserted into the ice-making cylinder 1 along with the rotating shaft 5. For example... Figure 6 The image shows the state when the first component 6 is inserted into the ice-making container 1, as shown below. Figure 8 The image shows the state of the self-made ice cylinder 1 of the first component 6 when it is pulled out. It can be seen that the first sealing ring 12 is taken away with the rotating shaft 5. The advantages of doing this are that, on the one hand, the ice cylinder 1 is emptied, and the clean flow channel formed by the ice cylinder 1 and the axial through hole 11 is unobstructed, which helps to improve cleaning efficiency and cleaning quality. On the other hand, the first sealing ring 12 can be rinsed and cleaned with the rotating shaft 5, which prevents the first sealing ring 12 from accumulating dirt.

[0047] Furthermore, the first sealing ring 12 can be further removed from the rotating shaft 5 for cleaning. For example, the first sealing ring 12 is detachably connected to the rotating shaft 5. So when the first sealing ring 12 is pulled out of the ice maker 1 along with the rotating shaft 5, it can be further removed from the rotating shaft 5 for cleaning, thereby cleaning more thoroughly and improving the cleaning quality.

[0048] In some embodiments, such as Figure 6 , 8 As shown, the lower end of the ice-making cylinder 1 is provided with an annular cavity 13, which guides the first sealing ring 12 and detachably fits it for sealing. In this way, the annular cavity 13 guides the first sealing ring 12, which is convenient for the user to install the first sealing ring 12. That is, the user can install the first sealing ring 12 by inserting the first component 6 into the ice-making cylinder 1. At the same time, the first sealing ring 12 guides the first component 6, reducing radial wobbling. Therefore, it also reduces the collision between the outer circumference of the stirring component 2 and the inner circumference of the ice-making cylinder 1, which can be described as killing two birds with one stone.

[0049] likeFigure 8 As shown, the annular cavity 13 is preferably configured as a cylindrical segment adapted to the first sealing ring 12.

[0050] In some embodiments, such as Figure 6 As shown, the rotating shaft 5 has a limiting part 14 at the upper end of the first sealing ring 12. This limiting part 14 axially limits the first sealing ring 12 between the limiting part 14 and the bottom of the lower end of the ice-making cylinder 1, which in this example is between the limiting part 14 and the bottom of the annular cavity 13. In this way, when the first component 6 is inserted into the ice-making cylinder 1, the first sealing ring 12 can be better installed in the correct position, while avoiding axial displacement. In addition, the first sealing ring 12 provides an axial elastic force to provide axial cushioning when the first component 6 is inserted into the ice-making cylinder 1, thereby reducing noise, collisions, etc.

[0051] Furthermore, such as Figure 6 As shown, the first sealing ring 12 is configured as two segments, upper and lower, with a reduced diameter between the two segments to achieve better performance.

[0052] like Figure 2 , 3 As shown in Figures 6 and 8, the ice-making cylinder 1 is, for example, a cylindrical cylinder, the stirring assembly 2 is, for example, a spiral rotor, and the first assembly 6 is axially inserted into the other side of the self-made ice cylinder 1 so that the spiral rotor can rotate within the cylindrical cylinder.

[0053] In some embodiments, such as Figure 1 , 6 As shown, the other side of the ice-making cylinder 1 is provided with a detachable end cap 9, which axially limits the first component 6. In this way, the first component 6 is axially limited.

[0054] In this example, the end cap 9 is threadedly connected to the other end of the ice maker 1.

[0055] like Figure 6 As shown, the output shaft 8 is connected to a bearing 10, which is used to rotatably support the output shaft 8. This provides better precision and rotatable support performance.

[0056] Furthermore, such as Figure 6 As shown, bearings 10 are provided on both sides of the output shaft 8. The bearing 10 on the side closer to the first component 6 is located at the insertion and mating part of the rotating shaft 5 and the output shaft 8, that is, the bearing 10 on the side closer to the first component 6 is located at the overlapping part of the insertion and mating.

[0057] The above description is merely an illustrative embodiment of this utility model. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in the scope of protection of this utility model are included within the scope of protection of this utility model.
