The plurality of impeller assemblies 120 are disposed on the transmission rod 110 , and the plurality of impeller assemblies 120 are arranged along the length direction of the transmission rod 110 .

Each impeller assembly 120 includes a plurality of impellers 122 . The plurality of impellers 122 of each impeller assembly 120 are arranged along the length direction of the transmission rod 110 , and the plurality of impellers 122 of each impeller assembly 120 are staggered along the circumferential direction of the transmission rod 110 .

Each impeller 122 is provided with a connecting hole 124 , and the transmission rod 110 is passed through the connecting hole 124 .

The hole wall of the connecting hole 124 is provided with a first fold line segment, and the portion of the transmission rod 110 corresponding to the first fold line segment is provided with a second fold line segment. The first fold line segment and the second fold line segment cooperate to limit the displacement of the impeller 122 in the circumferential direction of the transmission rod 110.

At least one of the impeller 122 and the transmission rod 110 is a metal part or a plastic part.

In detail, each impeller assembly 120 includes a plurality of impellers 122, each impeller 122 and the transmission rod 110 are metal parts, and the metal impeller 122 and the metal transmission rod 110 have high strength and good ductility, and are not easy to crack and break. The metal impeller 122 and the metal transmission rod 110 are connected, so that the probability of the impeller 122 and the transmission rod 110 breaking can be greatly reduced.

Alternatively, each impeller assembly 120 includes a plurality of impellers 122, and each impeller 122 and the transmission rod 110 are plastic parts. This arrangement has the advantages of high processing efficiency and low processing cost.

Further, the multiple impellers 122 of each impeller assembly 120 are arranged along the length direction of the transmission rod 110, and the multiple impellers 122 of each impeller assembly 120 are staggered along the circumferential direction of the transmission rod 110. That is, the distribution positions of the multiple impellers 122 of each impeller assembly 120 are defined, and this arrangement enables the impellers 122 of the multiple impeller assemblies 120 to contact the ice cubes in multiple directions and multiple angles, and can effectively push the ice cubes at different positions in the box body of the ice-making device to the fixed cover 210 of the box body, which is conducive to improving the ice-discharging efficiency of the ice-making device to achieve crushed ice or whole ice.

Further, as shown in FIG. 7 and FIG. 8 , each impeller 122 is provided with a connecting hole 124, the connecting hole 124 is provided with a first folded line segment, the transmission rod 110 is provided with a second folded line segment, the first folded line segment is arranged corresponding to the second folded line segment, and the first folded line segment and the second folded line segment cooperate to limit the displacement of the impeller 122 in the circumferential direction of the transmission rod 110. In other words, the first folded line segment and the second folded line segment are arranged so that the impeller 122 will not be displaced in the circumferential direction of the transmission rod 110. The first folded line segment and the second folded line segment cooperate to limit the impeller 122 from multiple directions and multiple angles, and the transmission rod 110 and the impeller 122 are assembled as a whole, which provides effective and reliable structural support for the transmission rod 110 to effectively drive the impeller 122 to rotate. This arrangement reasonably utilizes the existing structure of the connecting hole 124 and the transmission rod 110, and by adapting the shapes of the first folded line segment and the second folded line segment, it is beneficial to reduce the material input for assembling the impeller 122 and the transmission rod 110, and it is beneficial to reduce the production cost of the product, and it is beneficial to simplify the disassembly and assembly process of the product. The invention solves the problems in the related art that the ice rod and the impeller are assembled by using an additional limiting member, which leads to low product assembly efficiency, high product production cost and impeller failure due to the falling of the limiting member.

Embodiment 2:

On the basis of Example 1, further, the impeller 122 is cross-sectioned along a length direction perpendicular to the transmission rod 110. In the cross-section, the shape of the contour line of the first broken line segment is a polygon.

In detail, the structure of the impeller 122 is further defined. Specifically, the impeller 122 is sectioned along the length direction perpendicular to the transmission rod 110. In the section, the shape of the contour line of the first fold line segment is a polygon, such as a triangle, a quadrilateral, a pentagon, etc., which are not listed here. Of course, the shape of the contour line of the first fold line segment can also be a special shape, where the special shape refers to an irregular structure.

Specifically, taking the transmission rod 110 as a rectangular rod, the connecting hole 124 is a rectangular hole, and the rectangular rod passes through the rectangular hole. This arrangement can meet the use requirements of arranging multiple impellers 122 of each impeller group 120 along the length direction of the transmission rod 110, and can also meet the use requirements of staggered arrangement of multiple impellers 122 of each impeller group 120 along the circumferential direction of the transmission rod 110.

It is understandable that the shape of the first fold line segment and the shape of the second fold line segment are adapted. For example, the shape of the contour line of the first fold line segment is a rectangle, and the shape of the contour line of the second fold line segment is a rectangle. For another example, the shape of the contour line of the first fold line segment is a triangle, and the shape of the contour line of the second fold line segment is a triangle.

Of course, the shape of the contour line of the first fold line segment may also be a line segment, that is, the contour line has a break and is not a closed ring structure.

Embodiment 3:

On the basis of Example 1 or Example 2, further, along the circumference of the transmission rod 110, the multiple impellers 122 of each impeller group 120 are arranged at equal intervals.

In detail, the layout positions of the multiple impellers 122 of each impeller assembly 120 are further defined. Specifically, the multiple impellers 122 of each impeller assembly 120 are arranged at equal intervals along the circumference of the transmission rod 110. This arrangement enables the impellers 122 of the multiple impeller assemblies 120 to contact the ice cubes in multiple directions and multiple angles, and can effectively push the ice cubes at different positions in the box body of the ice-making device to the fixed cover 210 of the box body, which is conducive to improving the ice-discharging efficiency of the ice-making device to achieve crushed ice or whole ice.

In addition, this arrangement ensures that when the transmission assembly 100 is working, the forces at different positions of the transmission rod 110 are balanced and consistent, and the transmission rod 110 is not prone to tilting, thereby ensuring the stability and reliability of the use of the transmission assembly 100.

In some other embodiments, each impeller assembly 120 includes two impellers 122 , and the two impellers 122 are arranged at equal intervals.

In some other embodiments, each impeller assembly 120 includes four impellers 122 , and the four impellers 122 are arranged at equal intervals.

Embodiment 4:

As shown in FIG. 7 and FIG. 8 , on the basis of any of the above embodiments, the impeller 122 further includes a matching portion 128 and a wheel plate 130 .

The matching portion 128 defines a connecting hole 124 .

The wheel plate 130 is connected to one side of the matching portion 128 , and the matching portions 128 of any two adjacent impellers 122 abut against each other, so that the wheel plates 130 of any two adjacent impellers 122 are separated.

In detail, the impeller 122 includes a matching portion 128 and a wheel plate 130 . The wheel plate 130 is located at one side of the matching portion 128 , and the wheel plate 130 is connected to the matching portion 128 .

The matching portion 128 is provided with a connecting hole 124, and the wheel plate 130 is connected to the transmission rod 110 through the matching portion 128. It can be understood that the rotation of the transmission rod 110 can drive the matching portion 128 to rotate, and the rotation of the matching portion 128 can drive the wheel plate 130 to rotate.

The mating portion 128 supports and fixes the wheel plate 130 , so that the wheel plate 130 is separated from the transmission rod 110 , providing an escape space for the wheel plate 130 to rotate, and avoiding interference between the wheel plate 130 and the transmission rod 110 .

Furthermore, the mating portions 128 of any two adjacent impellers 122 abut against each other, that is, the mating positions of any two wheel plates 130 are limited. At the same time, the wheel plates 130 of the plurality of impellers 122 are prevented from moving in the length direction of the transmission rod 110 by the mating portions 128 .

As shown in FIG. 7 and FIG. 8 , further, the mating portion 128 includes a connecting plate 132 , a first rib plate 134 and a second rib plate 136 .

The connecting plate 132 defines a connecting hole 124 .

The first rib plate 134 is disposed on the connecting plate 132 , and the first rib plate 134 extends along the length direction of the transmission rod 110 .

Among any two adjacent impellers 122 , the first rib plate 134 of one impeller 122 abuts against the connecting plate 132 of the other impeller 122 .

The second rib plate 136 extends from the connecting plate 132 in a direction away from the transmission rod 110 , and the wheel plate 130 is connected to the second rib plate 136 .

Among them, the matching part 128 includes a connecting plate 132, a first rib plate 134 and a second rib plate 136. The first rib plate 134 and the second rib plate 136 are both connected to the connecting plate 132. The first rib plate 134 extends along the length direction of the transmission rod 110. In any two adjacent impellers 122, the first rib plate 134 of one impeller 122 abuts against the connecting plate 132 of the other impeller 122. That is to say, the distance between any two adjacent impellers 122 is fixed, and the distance is the size of the first rib plate 134 in the length direction of the transmission rod 110.

As shown in Figures 7 and 8, further, the second rib plate 136 is connected between the connecting plate 132 and the wheel plate 130, and the second rib plate 136 extends from the connecting plate 132 in a direction away from the transmission rod 110. The second rib plate 136 has the function of supporting the wheel plate 130, so that the wheel plate 130 is separated from the transmission rod 110.

That is to say, the first rib plate 134 and the second rib plate 136 cooperate to separate the wheel plates 130 of any two adjacent impellers 122, that is, the wheel plates 130 of any two adjacent impellers 122 will not interfere with each other. The size of the wheel plates 130 of the two adjacent impellers 122 in the length direction of the transmission rod 110 is guaranteed, and the size of the wheel plates 130 of the two adjacent impellers 122 in the length direction perpendicular to the transmission rod 110 is guaranteed. An escape space is provided for the wheel plates 130 to rotate, so as to avoid the interference between the wheel plates 130 and the transmission rod 110, and an escape space is provided for the wheel plates 130 to push the ice cubes to move.

This arrangement can prevent the plurality of impellers 122 from moving in the length direction of the transmission rod 110 .

Embodiment 5:

As shown in FIG. 1 and FIG. 2 , on the basis of Embodiment 4, the transmission assembly 100 further includes a first connecting portion 140 and a driving member 150 .

The first connecting portion 140 is connected to the transmission rod 110 .

The driving member 150 includes a second connecting portion 152 , the first connecting portion 140 is connected to the second connecting portion 152 , and the driving member 150 drives the transmission rod 110 to rotate along the first direction or the second direction through the first connecting portion 140 .

The first direction is opposite to the second direction.

At least one of the first connection portion 140 and the second connection portion 152 is a metal member or a plastic member.

The wheel plate 130 is bent in a direction away from the driving member 150 .

In detail, the transmission assembly 100 also includes a driving member 150, which can drive the transmission rod 110 to move in the first direction or the second direction. The driving member 150 drives the transmission rod 110 to move in different directions to meet different ice-discharging requirements. Among them, the movement of the transmission rod 110 in the first direction can achieve crushed ice, and the movement of the transmission rod 110 in the second direction can achieve whole ice. That is, one transmission assembly 100 can meet the use requirements of the multi-function of the ice-making equipment. This setting is conducive to improving the product's performance and market competitiveness.

Furthermore, the wheel plate 130 is bent in a direction away from the driving member 150. The bent arrangement of the wheel plate 130 can increase the contact area and contact angle between the wheel plate 130 and the ice cubes, which can ensure the effectiveness and feasibility of the wheel plate 130 in pushing the ice cubes to move, and is conducive to improving the ice-out efficiency. In addition, this arrangement enables the transmission rod 110 to smoothly output ice when it rotates in the first direction or in the second direction.

Further, the first connection portion 140 is connected to the transmission rod 110 , and the first connection portion 140 is connected to the second connection portion 152 , that is, the transmission rod 110 and the second connection portion 152 are connected via the first connection portion 140 .

The first connection part 140 and the second connection part 152 are both metal parts. The first connection part 140 and the second connection part 152 made of metal have high strength and good ductility, and are not easy to crack or break. The second connection part 152 of the driving member 150 contacts the first connection part 140 made of metal and transmits the driving force. The two metal parts transmit torque, so that the probability of the transmission assembly 100 breaking can be greatly reduced.

Alternatively, the first connection portion 140 and the second connection portion 152 are both plastic parts. This arrangement has the advantages of high processing efficiency and low processing cost.

It can be understood that the multiple impeller groups 120 are arranged along the length direction of the transmission rod 110, the driving member 150 can drive the transmission rod 110 to rotate, the rotation of the transmission rod 110 can drive the multiple impeller groups 120 to rotate, and the rotation of the multiple impeller groups 120 can drive the ice cubes to move.

In the related art, an electromagnet is used to drive the ice-dispensing rod to rotate unidirectionally to dispense ice. This setting cannot meet the use requirements of the same ice-making device to dispense both crushed ice and whole ice, and this setting has the hidden danger of electromagnet failure. The component of the driving member 150 of the present application (i.e., the second connecting portion 152) is directly connected to the first connecting portion 140, and the first connecting portion 140 is directly connected to the transmission rod 110. This setting can ensure that the driving member 150 is in effective contact with the transmission rod 110, and thus can ensure the effectiveness and stability of the driving member 150 driving the transmission rod 110 to rotate.

Specifically, the driving member 150 includes a motor, a pump, etc., which are not listed here one by one.

Specifically, the first connection part 140 includes a stainless steel connection part, an aluminum connection part, a copper connection part, etc., which are not listed here one by one.

Specifically, the second connection part 152 includes a stainless steel connection part, an aluminum connection part, a copper connection part, etc., which are not listed here one by one.

Specifically, the first direction is a clockwise direction, and the second direction is a counterclockwise direction, or the first direction is a counterclockwise direction, and the second direction is a clockwise direction.

Furthermore, the wheel plates 130 are arranged in a V-shape.

The structure of the wheel plate 130 is further defined. Specifically, the wheel plate 130 is arranged in a V shape. For example, the wheel plate 130 includes a first plate body and a second plate body, the first plate body is connected to the second plate body, and the first plate body and the second plate body surround a V shape, that is, the first plate body and the second plate body are symmetrically arranged. This arrangement ensures that ice can be smoothly discharged when the transmission rod 110 rotates in the first direction and the second direction.

Of course, the shape of the wheel plate 130 includes but is not limited to a V-shape, a "hook" shape, an arc shape, etc., which are not listed here one by one.

In some other embodiments, the first plate body and the second plate body are arranged asymmetrically.

Specifically, the wheel plate 130 is integrally stamped and formed. This arrangement simplifies the assembly and subsequent disassembly processes of the wheel plate 130 because the assembly process of the wheel plate 130 is omitted, which is conducive to improving the assembly and disassembly efficiency, thereby reducing the production and maintenance costs. In addition, the wheel plate 130 is integrally stamped and formed, which can ensure the dimensional accuracy requirements of the product molding.

Specifically, the wheel plates 130 of any two impellers 122 among the plurality of impellers 122 have the same bending direction, that is, the wheel plate 130 of each impeller 122 is bent in a direction away from the driving member 150 .

Specifically, the connection between the first plate body and the second plate body has a smooth transition, which avoids stress concentration and is conducive to extending the service life of the product.

Furthermore, the first connection part 140 and the transmission rod 110 can be detachably connected. That is, the detachability and installation positions of the first connection part 140 and the transmission rod 110 can be determined according to actual conditions, thereby being applicable to the use requirements of transmission assemblies 100 of different models, and the product has strong adaptability and improved product performance.

Furthermore, the first connection portion 140 and the second connection portion 152 are detachably connected.

Further, there are multiple second connection parts 152. The first connection part 140 is provided with multiple slots. Each second connection part 152 is matched with one slot. The multiple second connection parts 152 are arranged at intervals along the circumference of the transmission rod 110.

There are multiple second connection parts 152, and the first connection part 140 is provided with multiple slots, and each second connection part 152 is matched with one slot. Specifically, each slot is provided with a second connection part 152, or a part of the multiple slots is provided with a second connection part 152, that is, the second connection part 152 is engaged with the first connection part 140.

Since the plurality of second connection parts 152 are arranged at intervals along the circumference of the transmission rod 110, the plurality of slots cooperate with the plurality of second connection parts 152 to limit the displacement of the first connection part 140 relative to the second connection part 152 in the circumferential direction of the transmission rod 110. This arrangement increases the contact area and contact angle between the driving member 150 and the first connection part 140, so that the transmission rod 110 and the driving member 150 are connected as a whole, and the driving member 150 can effectively drive the transmission rod 110 to rotate when it works, and the problem of failure of the transmission rod 110 to rotate will not occur.

In this embodiment, the plurality of slots are arranged at equal intervals. When the number of the slots is greater than or equal to three, the intervals between any two of the plurality of slots are equal. This arrangement can ensure the balance and consistency of the forces at different positions of the first connecting portion 140, and the transmission rod 110 is not prone to tilt, thereby ensuring the stability and reliability of the transmission assembly 100.

In some other embodiments, when the number of the card slots is greater than or equal to three, the intervals between any two card slots in the plurality of card slots are not equal.

Of course, the detachable connection methods between the first connection part 140 and the transmission rod 110 include, but are not limited to, snap connection, threaded connection, connection via screws, bolts or rivets, etc., which are not listed here one by one.

Furthermore, the outer edge of the first connecting portion 140 is recessed toward the transmission rod 110 to form a plurality of slots.

Among them, the structure of the first connection part 140 is further defined, so that the outer edge of the first connection part 140 is recessed toward the direction of the transmission rod 110 to form a plurality of slots, that is, the first connection part 140 is integrally formed with a plurality of slots. This structural setting simplifies the assembly process of the first connection part 140 and the plurality of slots and the subsequent disassembly process, which is conducive to improving the assembly and disassembly efficiency, thereby reducing the production and maintenance costs. In addition, the first connection part 140 is integrally formed with a plurality of slots, which can ensure the dimensional accuracy requirements of the product molding.

Further, the first connection part 140 is provided with a first positioning hole, and the transmission rod 110 is connected to the first positioning hole. A fifth fold line segment is provided on the hole wall of the first positioning hole. A sixth fold line segment is provided on the portion of the transmission rod 110 corresponding to the fifth fold line segment. The fifth fold line segment and the sixth fold line segment cooperate to limit the displacement of the first connection part 140 in the circumferential direction of the transmission rod 110. The transmission assembly 100 also includes a fastener 220, and the transmission rod 110 and the first connection part 140 are connected by the fastener 220.

In this technical solution, the first connection part 140 is provided with a first positioning hole, the first positioning hole is provided with a fifth fold line segment, the transmission rod 110 is provided with a sixth fold line segment, the fifth fold line segment is arranged corresponding to the sixth fold line segment, and the fifth fold line segment and the sixth fold line segment cooperate to limit the displacement of the first connection part 140 in the circumferential direction of the transmission rod 110.
