Description

Technical Field

[0001] The present application relates to the technical field of ice making, and in particular to an ice blending assembly and an ice making machine. Background Art

[0002] The ice maker can produce large ice cubes in its ice making container and crush the ice cubes through the ice blending assembly to meet the usage requirements.

[0003] In the related art, the motor of the ice maker usually directly drives the ice stirring wheel through the output shaft. This design will produce a long lever arm, and accordingly, the required transmission torque is also large. In order to achieve the required transmission torque, a large-volume and high-power motor is required, which will also increase energy consumption and manufacturing costs. Summary of the invention

[0004] Based on this, it is necessary to provide an ice-mixing assembly and an ice-making machine that have lower power requirements for the ice-mixing motor in order to solve the above-mentioned problems.

[0005] An ice-mixing assembly, comprising:

[0006] An ice-stirring wheel, comprising an annular portion and a rotating shaft portion, wherein the rotating shaft portion is connected to the annular portion and is coaxially arranged with the annular portion, and the ice-stirring wheel is configured to be rotatable by the rotating shaft portion; and

[0007] The ice-stirring motor is transmission-connected to the annular portion and is configured to drive the ice-stirring wheel to rotate through the annular portion.

[0008] In the above-mentioned ice-stirring assembly, the position where the ice-stirring motor applies driving force to the ice-stirring wheel is located on the annular portion, that is, the force application point is offset from the rotation axis of the ice-stirring wheel and is closer to its edge area. Therefore, the lever arm is shortened, which reduces the output transmission torque of the required ice-stirring motor. Accordingly, the ice-stirring assembly can use a smaller power ice-stirring motor, which means that the ice-stirring assembly can have lower power consumption, which helps to improve the energy efficiency of the ice-making machine. The smaller size of the ice-stirring motor also helps to optimize the structural design and reduce the overall manufacturing cost.

[0009] In one embodiment, the ice stirring wheel further comprises a transmission gear ring, and the transmission gear ring is coaxially arranged on the annular portion;

[0010] The ice-mixing assembly also includes a driving gear, which is transmission-connected to the ice-mixing motor and meshes with the transmission gear ring.

[0011] In this way, the ice-mixing motor is connected to the annular portion through the driving gear and the transmission gear ring, thereby forming a stable drive for the annular portion, so that the torque output by the ice-mixing motor can be stably transmitted.

[0012] In one embodiment, the transmission gear ring is arranged on the inner ring of the annular portion; the ice-making wheel also includes an end cover portion, which is connected to one end of the annular portion in the axial direction and defines an inner wheel space with the annular portion, and the rotating shaft portion and the driving gear are both arranged in the inner wheel space.

[0013] In this way, the wheel inner space formed by the end cover can be separated from other areas in the inner container, the rotating shaft and the driving gear can work stably, and the interference of ice cubes and their debris can be reduced.

[0014] In one of the embodiments, the ice-stirring wheel further comprises an ice-stirring blade, which is disposed on a side of the end cover portion facing away from the annular portion and is engaged with the end cover portion in a direction of rotation around the axis of the rotating shaft portion.

[0015] In this way, the ice-stirring blade cooperates with the end cover portion to prevent rotation, and can be driven by the ice-stirring motor together with the annular portion and the end cover portion, and the ice-stirring blade can crush the ice cubes in the inner tank during the rotation process.

[0016] In one embodiment, the ice stirring knife has at least two blade heads, and all of the blade heads are arranged around the axis of the annular portion;

[0017] And / or, one of the ice stirring blade and the end cover has an axial hole, and the other has an anti-rotation assembly portion; the axial hole is a non-circular hole, and the anti-rotation assembly portion cooperates with the axial hole.

[0018] In this way, the ice-scraping blade has a plurality of blade heads, which is helpful to improve its ice-crushing efficiency. When the end cover part rotates around its axial direction along with the annular part, the end cover part can transmit torque to the ice-scraping blade through the anti-rotation assembly part and drive it to rotate.

[0019] In one embodiment, the ice-mixing assembly further includes an ice-mixing blade, and the ice-mixing blade is disposed on the outer ring of the annular portion.

[0021] In one embodiment, the ice-mixing assembly further includes a bracket and a central axis, the ice-mixing motor and the central axis are disposed on the bracket, and the rotating shaft portion rotates with the central axis around its own axis.

[0022] In this way, the bracket can provide support for the stable installation of the ice-mixing motor, and the central axis can help the ice-mixing wheel to achieve a rotatable setting.

[0023] In one embodiment, the ice-making assembly further includes a sealing cover, which is connected to the bracket and is configured to clamp the inner tank with the bracket at the inner and outer sides of the inner tank of the ice maker respectively; the central axis passes through the sealing cover, and a seal is formed between the sealing cover and the central axis.

[0024] In this way, the sealing cover cooperates with the bracket to be stably fixed on the inner container. At the same time, a seal can be formed at the assembly position of the central axis to improve the sealing performance of the inner container.

[0025] In one embodiment, the rotating shaft portion is sleeved on the central shaft, and the ice stirring assembly further includes a fixing nut, and the fixing nut is matched with one end of the central shaft;

[0026] The central shaft has a first table surface, a second table surface and a third table surface protruding along its radial direction, the first table surface abuts against the bracket, the second table surface abuts against one end of the rotating shaft, and the third table surface abuts against the fixing nut.

[0027] In this way, when assembling, you only need to insert the end that cooperates with the fixing nut into the inner pot from the first assembly hole until the first table surface of the central axis abuts the bracket, then assemble the sealing cover on one side of the inner pot, stir the ice, and finally tighten the nut.

[0028] An ice-making machine comprises the above-mentioned ice-mixing assembly.

[0029] In the above-mentioned ice-making machine, the position where the ice-stirring motor applies driving force to the ice-stirring wheel is located on the annular portion, that is, the force application point is offset from the rotation axis of the ice-stirring wheel and is closer to its edge area. Therefore, the lever arm is shortened, which reduces the output transmission torque of the required ice-stirring motor. Accordingly, the ice-stirring assembly can use a smaller power ice-stirring motor, which means that the ice-stirring assembly can have lower power consumption, which helps to improve the energy efficiency of the ice-making machine. The smaller size of the ice-stirring motor also helps to optimize the structural design and reduce the overall manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Referring to FIGS. 1 to 3 , an ice maker 100 provided in one embodiment of the present application includes an ice stirring assembly 10. In addition, to realize its normal function, the ice maker 100 also includes an inner tank 30, an ice making assembly, a base 50, and an insulation layer 70. Among them, the inner tank 30 is used as a container for ice production, and the ice making assembly is used to form a low temperature in the inner tank 30. The base 50 is arranged at the bottom of the inner tank 30 to support the inner tank 30. The insulation layer 70 is arranged outside the inner tank 30 to wrap the inner tank 30 and reduce the heat exchange efficiency between the inner tank 30 and the outside.

[0043] The present application also provides an ice-stirring assembly 10, comprising an ice-stirring wheel 11 and an ice-stirring motor 12. The ice-stirring wheel 11 comprises an annular portion 111 and a rotating shaft portion 112, the rotating shaft portion 112 is connected to the annular portion 111 and is coaxially arranged with the annular portion 111, and the ice-stirring wheel 11 is configured to be able to rotate through the rotating shaft portion 112. The ice-stirring motor 12 is transmission-connected to the annular portion 111, and is configured to be able to drive the ice-stirring wheel 11 to rotate through the annular portion 111.

[0044] The ice stirring assembly 10 can be used in the ice making machine 100 described above and assembled on the inner container 30. Specifically, the ice stirring wheel 11 is located in the inner container 30, and the ice stirring motor 12 can be located outside the inner container 30, and its output shaft can pass through the inner container 30 to drive the ice stirring wheel 11 located in the inner container 30.

[0045] The rotating shaft 112 of the ice stirring assembly 10 can be connected to the annular portion 111 as a whole, and the axes of the two coincide, and the ice stirring wheel 11 can rotate in the inner container 30 through the rotating shaft 112 to work. It can be understood that the rotation axis of the ice stirring wheel 11 is the axis of the rotating shaft 112 and the annular portion 111.

[0046] The ice-mixing motor 12 drives the ice-mixing wheel 11 to rotate via the annular portion 111 , which means that the torque output by the ice-mixing motor 12 acts on the annular portion 111 , thereby driving the ice-mixing wheel 11 to rotate.

[0047] In the above-mentioned ice-stirring assembly 10, the position where the ice-stirring motor 12 applies driving force to the ice-stirring wheel 11 is located on the annular portion 111, that is, the force application point deviates from the rotation axis of the ice-stirring wheel 11 and is closer to its edge area. Therefore, the lever arm is shortened, which reduces the output transmission torque of the required ice-stirring motor 12. Accordingly, the ice-stirring assembly 10 can use a smaller power ice-stirring motor 12, which means that the ice-stirring assembly 10 can have lower power consumption, which helps to improve the energy efficiency of the ice-making machine 100, and the smaller size of the ice-stirring motor 12 also helps to optimize the structural design and reduce the overall manufacturing cost.

[0048] In some embodiments, the ice-stirring wheel 11 further includes a transmission gear ring 113 , which is coaxially disposed on the annular portion 111 . The ice-stirring assembly 10 further includes a driving gear 13 , which is transmission-connected to the ice-stirring motor 12 and meshes with the transmission gear ring 113 .

[0049] Specifically, the transmission gear ring 113 may be disposed on at least one of the inner ring, the outer ring and the end of the annular portion 111. The driving gear 13 is sleeved on the output shaft of the ice-mixing motor 12 and is rotationally fixedly connected to the output shaft of the ice-mixing motor 12.

[0050] In this way, the ice-mixing motor 12 is connected to the annular portion 111 through the driving gear 13 and the transmission ring gear 113, so as to stably drive the annular portion 111, so that the torque output by the ice-mixing motor 12 can be stably transmitted.

[0051] In some embodiments, the transmission gear ring 113 is disposed on the inner ring of the annular portion 111. The ice stirring wheel 11 further includes an end cover 114, which is connected to one end of the annular portion 111 in the axial direction and defines an inner wheel space 115 with the annular portion 111. The shaft portion 112 and the driving gear 13 are both disposed in the inner wheel space 115.

[0052] In this way, the inner wheel space 115 formed by the end cover portion 114 can be separated from other areas in the inner container 30, and the rotating shaft portion 112 and the driving gear 13 can work stably, reducing the interference of ice cubes and their debris.

[0053] Specifically, the shaft portion 112 is disposed on the side of the end cover portion 114 facing the surface of the inner container 30 of the ice maker 100, and the end cover portion 114 also has a plurality of support ribs 1141, and all the support members are disposed on the circumference of the shaft portion 112. Specifically, the annular portion 111, the shaft portion 112 and the end cover portion 114 are integrally connected.

[0054] In some other embodiments, the transmission gear ring 113 may also be arranged on the outer ring of the annular portion 111, and the ice stirring blades 117, the driving gear 13 and the ice stirring motor 12 are arranged accordingly. In addition, the transmission mode between the ice stirring motor 12 and the ice stirring wheel 11 may also be belt rotation, chain transmission, worm transmission, etc., which are not specifically limited here.

[0055] In some embodiments, the ice-stirring wheel 11 further includes an ice-stirring blade 116 , which is disposed on a side of the end cover 114 facing away from the annular portion 111 and is engaged with the end cover 114 in a direction of rotation around the axis of the rotating shaft 112 .

[0056] In this way, the ice-stirring blade 116 is engaged with the end cover 114 to prevent rotation, and can be driven by the ice-stirring motor 12 together with the annular portion 111 and the end cover 114 . The ice-stirring blade 116 can crush the ice cubes in the inner container 30 during the rotation process.

[0057] Furthermore, the ice stirring knife 116 has at least two knife heads 1161 , and all the knife heads 1161 are arranged around the axis of the annular portion 111 .

[0058] Thus, the ice-crushing blade 116 has a plurality of blade heads 1161 , which helps to improve its ice-crushing efficiency.

[0059] Furthermore, one of the ice stirring blade 116 and the end cover 114 has an axial hole 1163 , and the other has an anti-rotation assembly portion 1143 ; the axial hole 1163 is a non-circular hole, and the anti-rotation assembly portion 1143 cooperates with the axial hole 1163 .

[0060] It can be understood that the shaft hole 1163 is coaxially arranged with the annular portion 111, and the cutter head 1161 is arranged around the shaft hole 1163. The cross section of the anti-rotation assembly portion 1143 is substantially the same as the shape of the shaft hole 1163, and the shaft hole 1163 can be substantially square, oval, triangular, etc., as long as it can form an anti-rotation fit with the anti-rotation assembly portion 1143 in the direction of rotation around the axis of the annular portion 111.

[0061] In this way, when the end cover portion 114 rotates along with the annular portion 111 around its axial direction, it can transmit torque to the ice-stirring blade 116 through the anti-rotation assembly portion 1143 and drive the ice-stirring blade 116 to rotate.

[0062] In some embodiments, the ice-mixing assembly 10 further includes an ice-mixing blade 117 , which is disposed on the outer ring of the annular portion 111 .

[0063] It can be understood that the inner container 30 has an ice outlet 31, and the ice outlet 31 is located on the side wall where the ice-stirring wheel 11 is installed. The ice-stirring blade 117 has an ice-taking surface inclined toward the ice outlet 31. When the ice-stirring blade 117 rotates to the bottom area of ​​the inner container 30 and contacts the broken pieces of ice cubes, some of the broken pieces can fall into the ice-taking surface, and reach the ice outlet 31 as the annular portion 111 rotates and is discharged from the ice outlet 31.

[0064] In this way, the ice-mixing assembly 10 can also realize an automatic ice-taking function, and the crushed ice cubes can be output from the ice outlet 31 of the inner tank 30 driven by the ice-mixing blades 117 .

[0065] Specifically, the annular portion 111 , the transmission gear ring 113 , the rotation shaft portion 112 and the ice-stirring blades 117 together constitute a main body of the ice-stirring wheel 11 , and the ice-stirring blades 116 are assembled to the main body.

[0066] The annular portion 111 , the transmission gear ring 113 , the rotating shaft portion 112 and the ice stirring blade 117 can be made of the same material, and they can be synchronously moved, so they can be integrally formed. The ice stirring blade 116 can be made of metal material and assembled to the main body to form the ice stirring wheel 11 .

[0067] Please refer to FIG. 4 . In some embodiments, the ice-mixing assembly 10 further includes a bracket 14 and a central shaft 15 . The ice-mixing motor 12 and the central shaft 15 are disposed on the bracket 14 . The rotating shaft 112 rotates with the central shaft 15 around its own axis.

[0068] The bracket 14 is used to fix the inner container 30, and the bracket 14 itself can be located outside the inner container 30, and the ice-mixing motor 12 is fixed on the bracket 14. The central shaft 15 can be inserted into the inner container 30 and rotated with the rotating shaft 112. The central shaft 15 and the rotating shaft 112 can be nested, with one coaxially nested in the other. The inner container 30 is provided with a first assembly hole for the central shaft 15 to pass through and a second assembly hole for the output shaft of the ice-mixing motor 12 to pass through.

[0069] In this way, the bracket 14 can provide support for the stable installation of the ice-mixing motor 12, and the central shaft 15 can help the ice-mixing wheel 11 to be rotatable.

[0070] Furthermore, the ice stirring assembly 10 further includes a sealing cover 16, which is connected to the bracket 14 and is configured to clamp the inner container 30 with the bracket 14 at both inner and outer sides of the inner container 30 of the ice maker 100. The central shaft 15 passes through the sealing cover 16, and a seal is formed between the sealing cover 16 and the central shaft 15.

[0071] Specifically, the sealing cover 16 includes a cover body 161 and a sealing ring 163 . The sealing cover 16 and the bracket 14 clamp the inner liner 30 together. The sealing ring 163 is sleeved on the central axis 15 , and a seal is formed at the first assembly hole on the central axis 15 .

[0072] In this way, the sealing cover 16 cooperates with the bracket 14 to be stably fixed on the inner container 30 . At the same time, a seal can be formed at the assembly position of the central axis 15 to improve the sealing performance of the inner container 30 .

[0073] Furthermore, the shaft portion 112 is sleeved on the central shaft 15, and the ice stirring assembly 10 further includes a fixing nut 17, which is matched with one end of the central shaft 15. The central shaft 15 has a first table 151, a second table 153, and a third table 155 protrudingly arranged along its radial direction, the first table 151 abuts against the bracket 14, the second table 153 abuts against one end of the shaft portion 112, and the third table 155 abuts against the fixing nut 17.

[0074] It can be understood that the diameter of the first table 151 is larger than the diameter of the first assembly hole, the diameter of the second table 153 is larger than the inner diameter of the shaft portion 112 , and the diameter of the third table 155 is larger than the inner diameter of the fixing nut 17 .

[0075] Specifically, the fixing nut 17 is matched with one end of the central shaft 15 located in the inner container 30, the sealing cover 16 is sleeved between the first table 151 and the second table 153, and the ice-stirring wheel 11 is sleeved between the second table 153 and the third table 155. The central shaft 15 clamps the bracket 14, the wall of the inner container 30, the sealing cover 16, the ice-stirring wheel 11 and the ice-stirring blade 116 together through its first table 151 and the fixing nut 17.

[0076] In this way, when assembling, it is only necessary to insert the end that cooperates with the fixing nut 17 into the inner pot 30 from the first assembly hole until the first table 151 of the central axis 15 abuts the bracket 14, and then assemble the sealing cover 16 on one side of the inner pot 30, stir the ice, and finally tighten the nut.

[0077] For ease of understanding, the assembly process is briefly described below: first, the ice-stirring motor 12 and the central shaft 15 are fixed to the bracket 14; then, the bracket 14 is fixedly connected to the inner tank 30 of the ice-making machine 100, wherein the central shaft 15 and the output shaft of the ice-stirring motor 12 will both pass through the inner tank 30; then, the sealing cover 16 is installed, and the sealing cover 16 is connected to the bracket 14 by screws, thereby tightening the inner tank 30 to achieve the sealing of the inner tank 30 at the first assembly hole; next, the driving gear 13 is fixed to the output shaft of the ice-stirring motor 12, and finally, the main body of the ice-stirring wheel 11 is assembled to the central shaft 15 through its rotating shaft portion 112, and at the same time, ensure that the driving gear 13 is meshed with the transmission gear ring 113 of the ice-stirring wheel 11; finally, the ice-stirring knife 116 is fixed to the main body of the ice-supporting wheel and fixed by screws.

[0078] When the ice maker 100 makes ice, ice cubes are stored at the bottom of the inner tank 30 of the ice stirring assembly 10. The ice cubes are stirred into granules by the ice stirring blades 116. The granular ice cubes slide between the ice stirring blades 117 and the ice stirring blades 117. Finally, the ice stirring motor 12 drives the ice stirring wheel 11 to rotate, and the granular ice cubes at the bottom are transferred to the ice outlet 31, thereby realizing automatic ice discharging.

[0079] In this way, although the main body of the ice-stirring wheel 11 rotates synchronously with the ice-stirring blade 116 and shares the ice-stirring motor 12, the transmission position of the ice-stirring motor 12 to the ice-stirring wheel 11 deviates from the axis and is close to the edge area. In other words, the ice-stirring assembly 10 forms a support drive on the inner ring of the annular portion 111 by optimizing the gear arrangement, shortens the lever arm, and reduces the output transmission torque of the required ice-stirring motor 12. Since the required torque is reduced, the required output torque of the ice-stirring motor 12 is reduced, and the ice-stirring assembly 10 can select a smaller power ice-stirring motor 12, which means that the ice-stirring assembly 10 can have lower power consumption, which helps to improve the energy efficiency of the ice-making machine 100, and the smaller size of the ice-stirring motor 12 also helps to optimize the structural design and reduce the overall manufacturing cost.

[0080] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
