DETAILED DESCRIPTION

[0051] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

In order to avoid unnecessary repetition, various possible combinations of the specific technical features in the present invention will not be described separately.

[0053] In the following description, the terms "first\second\..." are only used to distinguish different objects, and do not mean that the objects have the same or related points. It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the specific corresponding schematic diagrams, which may be the left and right directions in normal use or not.

[0054] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0055] The embodiment of the present application further provides a stirring device, including a stirring rod 2 and a stirring wheel assembly 100 .

[0056] See also Figure 1 The stirring wheel assembly 100 includes a stirring wheel 10 , a driving mechanism 3 and a locking member 4 .

[0057] The stirring wheel 10 includes a wheel disc 11 and a mounting seat 12 disposed on the wheel disc 11. The stirring rod 2 is detachably connected to the mounting seat 12.

[0058] See also Figure 2 and Figure 3 The top side of the mounting seat 12 has an opening 12 b.

[0059] The driving mechanism 3 is connected to the mounting seat 12 and covers the opening 12 b. In other words, the mounting seat 12 provides mounting support for the driving mechanism 3 .

[0060] Since the driving mechanism 3 is connected to the mounting seat 12 , when the stirring rod 2 is removed from the stirring wheel assembly 100 , the driving mechanism 3 will not be removed along with the stirring rod 2 , and the driving mechanism 3 will still remain on the mounting seat 12 .

[0061] The locking member 4 is connected to the driving mechanism 3. The driving mechanism 3 is used to drive the locking member 4 to move between a locking position and an unlocking position.

[0062] In the locked position, the locking member 4 locks the stirring rod 2 on the stirring wheel assembly 100. Fig.12 , Fig.12 The locking member 4 is in the locking position.

[0063] In the unlocked position, the locking member 4 releases the stirring rod 2 so that the stirring rod 2 can be separated from the stirring wheel assembly 100. Fig.15 , Fig.15 The locking member 4 is in the unlocked position.

[0064] In the stirring wheel assembly 100 of the embodiment of the present application, since the driving mechanism 3 is arranged on the mounting seat 12, there is no need to arrange the driving mechanism 3 in the stirring rod 2, which can simplify the structure of the stirring rod 2, which is beneficial to improving the structural strength of the stirring rod 2, making the stirring rod 2 compact, reducing the outer diameter of the stirring rod 2, reducing the washing space occupied by the stirring rod 2, and relatively increasing the space for accommodating the laundry.

[0065] The stirring wheel assembly 100 of the embodiment of the present application is convenient for the user to choose to operate with the stirring rod 2 or without the stirring rod 2 according to the use needs. Specifically, when it is necessary to operate with the stirring rod 2, the locking member 4 is used to lock the stirring rod 2 on the mounting seat 12 to realize the detachable installation of the stirring rod 2; when it is not necessary to operate with the stirring rod 2, the locking member 4 can be driven by the driving mechanism 3 to switch from the locking position to the unlocking position, and the stirring rod 2 can be lifted up so that the stirring rod 2 is separated from the stirring wheel 10. When the stirring device is operated without the stirring rod 2, since the driving mechanism 3 covers the opening 12b, the edge of the opening 12b is not easy to scratch the clothes, and the mounting seat 12 is not easy to damage and tear the clothes, which has a good protective effect on the clothes.

[0066] The stirring device of the embodiment of the present application drives the locking member 4 to move through the driving mechanism 3, thereby locking or unlocking the stirring rod 2. No special tools such as screwdrivers are required, which makes it easy for users to install and disassemble the stirring rod 2, thereby improving user experience.

[0067] It should be noted that when the stirring rod 2 is installed on the stirring wheel assembly 100 , there is no need to remove any structure of the driving mechanism 3 .

[0068] For example, see Fig. 9 and Fig.10 The side wall of the stirring rod 2 has a locking groove 2a. The side wall of the mounting seat 12 is provided with an escape opening 12c. Specifically, the escape opening 12c penetrates the side wall of the mounting seat 12. The locking member 4 is arranged in the mounting space 12a.

[0069] In the locked position, the end of the locking member 4 away from the driving mechanism 3 passes through the avoidance opening 12c and is inserted into the locking groove 2a. Specifically, the end of the locking member 4 away from the driving mechanism 3 extends to the circumferential outer side of the mounting seat 12, that is, protrudes from the circumferential outer surface of the mounting seat 12. Fig.12 , Fig.12 The locking member 4 is in the locking position.

[0070] In the unlocking position, the end of the locking member 4 away from the driving mechanism 3 is retracted into the escape opening 12c or the installation space 12a, so that the stirring rod 2 can be separated from the stirring wheel 10. Fig.15 , Fig.15 The locking member 4 is in the unlocked position.

[0071] It should be noted that, in the locked position, the locking member 4 prevents the stirring rod 2 from rotating relative to the mounting seat 12 , and can also prevent the stirring rod 2 from moving upward, that is, prevents the stirring rod 2 from detaching upward from the mounting seat 12 .

[0072] It can be understood that when the locking member 4 is located at the unlocking position, the locking member 4 withdraws from the locking slot 2 a , so that the stirring rod 2 is easily removed from the stirring wheel assembly 100 .

[0073] Exemplarily, the mounting seat 12 is located in the middle area of ​​the wheel disc 11 and protrudes upward from the top surface of the stirring wheel 10 .

[0074] See also Fig.12 and Fig.15 , the bottom end of the stirring rod 2 is covered on the periphery of the mounting seat 12. That is to say, at least the top end of the mounting seat 12 extends into the interior of the stirring rod 2. In this way, the mounting seat 12 forms a lateral constraint on the stirring rod 2, which can improve the connection reliability between the stirring rod 2 and the mounting seat 12 and reduce the probability of lateral deflection of the stirring rod 2. Among them, the lateral direction refers to any direction perpendicular to the height direction of the stirring rod 2.

[0075] For example, see Figure 2 and Figure 3 The mounting seat 12 has a mounting space 12a. The top side of the mounting space 12a is open and defines the above-mentioned opening 12b.

[0076] For example, see Fig. 9 and Fig.10 A spiral blade 22 is arranged around the stirring rod 2, and the spiral blade 22 helps to stir the clothes.

[0077] For example, see Figure 3 The top surface of the wheel disc 11 is provided with a water-repelling ridge 111 , and the water-repelling ridge 111 is used to fluctuate the water flow and the laundry during the rotation of the agitator wheel 10 .

[0078] There is no limitation on the connection method between the mounting base 12 and the wheel disc 11, for example, including but not limited to detachable connection such as screws and bolts, or non-detachable connection such as welding, riveting, integral injection molding, etc.

[0079] In some embodiments, the mounting seat 12 and the wheel disc 11 are integrally formed, for example, integrally injection molded.

[0080] The connection method between the locking member 4 and the mounting seat 12 is not limited, as long as the locking member 4 can be easily moved on the mounting seat 12 and can be switched between the locking position and the unlocking position under the drive of the driving mechanism 3.

[0081] For example, in some embodiments, the locking member 4 can slide relative to the mounting seat 12 along a straight line or a curve.

[0082] Exemplarily, the locking member 4 is rotatably connected to the mounting seat 12 , and the driving mechanism 3 is used to drive the locking member 4 to swing between a locking position and an unlocking position.

[0083] In this embodiment, since the locking member 4 is rotationally connected to the mounting seat 12, the locking member 4 is not prone to getting stuck when the driving mechanism 3 drives the mounting seat 12 to swing. In addition, the space required for the locking member 4 to swing is relatively small, which makes it easy to reduce the size of the mounting seat 12 and make the structure compact.

[0084] The rotational connection method between the locking member 4 and the mounting seat 12 is not limited.

[0085] For example, see Figure 7 , the locking member 4 is provided with shaft portions 41 on opposite sides, see Figure 3 The mounting seat 12 is provided with an axial hole 12f, and the shaft portion 41 is inserted into the axial hole 12f and can rotate in the axial hole, thereby realizing the rotational connection between the locking member 4 and the mounting seat 12.

[0086] In other embodiments, axial holes may be provided on both the locking member 4 and the mounting seat 12, and a separate rotating shaft passes through the axial hole on the locking member 4 and the axial hole on the mounting seat 12 to achieve a rotational connection between the locking member 4 and the mounting seat 12.

[0087] In some further embodiments, an axial hole may be provided on the locking member 4 , and an axial portion may be provided on the mounting seat 12 . The axial portion is inserted into the axial hole and can rotate in the axial hole, thereby realizing a rotational connection between the locking member 4 and the mounting seat 12 .

[0088] Exemplarily, a portion of the drive mechanism 3 protrudes from the top edge of the mounting seat 12 and covers the opening 12b. In other words, a portion of the drive mechanism 3 extends upward to the top of the mounting space 12a. The rest of the drive mechanism 3 is accommodated in the mounting space 12a. In this embodiment, the mounting seat 12 plays a certain protective role on the drive mechanism 3, reduces the contact area between the drive mechanism 3 and the clothes, and reduces the probability of clothes being entangled.

[0089] For example, see Figure 2 The driving mechanism 3 includes a pressing member 31 and an elastic member 34 .

[0090] The pressing piece 31 covers the opening 12 b.

[0091] See also Fig.12 and Fig.15 The elastic member 34 is disposed in the installation space 12a. The pressing member 31 is supported by the elastic member 34. Since the elastic member 34 can produce elastic deformation, the pressing member 31 can reciprocate up and down.

[0092] When the stirring device is operated without the stirring rod 2 , the water flow may generate a downward impact force on the pressing member 31 at certain moments, so that the pressing member 31 moves downward and the elastic member 34 is compressed to store energy.

[0093] In this embodiment, when the stirring device is operated without the stirring rod 2, the pressing member 31 can float up and down continuously to beat the clothes under the impact of the water flow and the interaction of the elastic member 34, which can improve the washing power, shake out the clothes, reduce the chance of clothes being entangled, and further prevent the clothes from being damaged.

[0094] For example, see Fig.10 , Fig.12 and Fig.15 The stirring rod 2 has an abutment portion 21 inside, and the abutment portion 21 is used to detachably contact the pressing member 31 to push the pressing member 31 to move toward the bottom side of the mounting seat 12, and drive the locking member 4 to move from the locked position to the unlocked position. When the pressing member 31 is not pressed, the locking member 4 is in the locked position. When the pressing member 31 is pressed and moves downward for a distance, the locking member 4 is in the unlocked position. When the locking member 4 is in the unlocked position, if the pressure on the pressing member 31 is cancelled, the pressing member 31 will drive the locking member 4 to return to the locked position under the action of the elastic member 34. That is, the default initial position of the locking member 4 is the locked position.

[0095] For example, when the stirring rod 2 needs to be installed on the mounting seat 12, align the bottom end of the stirring rod 2 with the mounting seat 12, and move the stirring rod 2 downward. When the abutment portion 21 contacts the pressing piece 31, the pressing piece 31 is forced to move downward. When the pressing piece 31 moves downward, the elastic piece 34 is compressed and stores energy. The pressing piece 31 can directly or indirectly drive the locking piece 4 to move, so that the locking piece 4 moves from the locked position to the unlocked position.

[0096] In this way, the locking member 4 can avoid the stirring rod 2 and move the stirring rod 2 downward until the stirring rod 2 moves to the position where the locking member 4 locks the stirring rod 2. For example, when the locking member 4 moves to the position where the locking groove 2a is aligned with the end of the locking member 4, the locking member 4 automatically pops into the locking groove 2a, and the locking member 4 locks the stirring rod 2. After that, the stirring rod 2 can be released. When the stirring rod 2 needs to be removed, the stirring rod 2 is pressed downward, and the pressing member 31 is forced to move downward by the abutting portion 21, so that the locking member 4 is switched to the unlocked state, so that the stirring rod 2 can be pulled upward out of the stirring wheel assembly 100.

[0097] For example, see Figure 2 The pressing member 31 includes a cover portion 311 , and the cover portion 311 is disposed to cover the opening 12 b . In other words, the driving mechanism 3 covers the opening 12 b through the cover portion 311 .

[0098] See also Figure 5 and Figure 6 From the periphery of the cover portion 311 toward the center area thereof, the cover portion 311 protrudes toward the top side and at least partially exceeds the top edge of the mounting seat 12 .

[0099] The structure of the cover portion 311 can better protect the clothes and further reduce the chance of damage to the clothes.

[0100] Exemplarily, the housing portion 311 is substantially bowl-shaped.

[0101] For example, see Fig.12 and Fig.15 , the periphery of the shell portion 311 extends into the opening 12b and slides with the inner wall of the opening 12b. On the one hand, during the up and down movement of the pressing member 31, the shell portion 311 and the mounting seat 12 always overlap in height along the axial direction, that is, the edge of the bottom end of the shell portion 311 is always located in the opening 12b, and there is no gap between the two along the height direction. In this way, when the stirring device is running without the stirring rod 2, it is not easy for clothes to enter the mounting seat 12 from the junction of the shell portion 311 and the mounting seat 12, reducing the probability of clothes getting stuck in the mounting seat 12; in addition, the movement of the shell portion 311 plays a guiding role, preventing the shell portion 311 from hitting the mounting seat 12 during the up and down movement.

[0102] For example, see Figure 4 The stirring wheel 10 has a connecting hole 12d, and the connecting hole 12d penetrates the stirring wheel 10 in the axial direction.

[0103] See also Figure 5 and Figure 6 The pressing member 31 includes a connecting column 312. The top end of the connecting column 312 is connected to the housing portion 311, and the bottom end of the connecting column 312 is slidably inserted into the connecting hole 12d. Specifically, the connecting column 312 passes through the connecting hole 12d from top to bottom, and the matching relationship between the two allows the connecting column 312 to slide up and down in the connecting hole 12d.

[0104] See also Figure 2 A limiting member 3121 is provided at the bottom side of the connecting column 312 of the stirring wheel 10 , and the limiting member 3121 is used to cooperate with the bottom side stopper of the stirring wheel 10 .

[0105] Specifically, when the pressing member 31 slides downward, the connecting column 312 drives the limiting member 3121 to move downward, and the limiting member 3121 is not blocked by the stirring wheel 10. When the pressing member 31 slides upward under the elastic force of the elastic member 34, the connecting column 312 drives the limiting member 3121 to move upward. After moving a certain distance, the limiting member 3121 contacts the stirring wheel 10, so that the connecting column 312 cannot continue to move upward, thereby stopping the pressing member 31 from moving upward. The position at this time is the limit position of the upward movement of the pressing member 31, which can also be understood as the initial position of the pressing member 31.

[0106] The specific structure of the position-limiting member 3121 is not limited. For example, in some embodiments, it can be a pin connected to the connecting column 312, and the pin extends roughly along the radial direction of the connecting column 312. In other embodiments, the position-limiting member 3121 includes a screw and a gasket, the screw is screwed into the bottom end of the connecting column 312 along the axial direction, and the gasket is clamped between the end cap of the screw and the connecting column 312. The stopper 3121 and the stirring wheel 10 are realized by the gasket, which is also convenient for connection.

[0107] In some embodiments, the elastic member 34 is sleeved on the connecting column 312. For example, the elastic member 34 is a compression spring, and is sleeved on the connecting column 312, and the connecting column 312 plays a role in installing and guiding the compression spring.

[0108] The number of the connecting pillars 312 may be one or more.

[0109] In the embodiment of the present application, a plurality refers to no less than two.

[0110] For example, see Figure 5 and Figure 6 The pressing member 31 includes a guide tube portion 313 , and a top end of the guide tube portion 313 is connected to the cover portion 311 .

[0111] See also Figure 3 , Fig.12 and Fig.15 The mounting seat 12 has a guide column 121, which is disposed in the mounting space 12a. The guide cylinder portion 313 is sleeved on the outer periphery of the guide column 121 and the two are slidably matched. In this embodiment, the sliding match between the guide cylinder portion 313 and the guide column 121 provides a good guiding effect for the movement of the pressing member 31.

[0112] In some embodiments, the guide cylinder portion 313 and the guide column 121 are both located on the rotation axis of the stirring wheel 10 .

[0113] In some embodiments, the plurality of connection posts 312 are evenly spaced around the circumference of the guide cylinder portion 313 .

[0114] For example, see Figure 2 The driving mechanism 3 includes a ring body 32 and an elastic connecting member 33. Fig.12 and Fig.15 The ring body 32 is slidably mounted on the guide column 121 and is located at the bottom side of the guide cylinder portion 313 .

[0115] See also Figure 7 The elastic connecting member 33 connects the locking member 4 and the ring body 32 .

[0116] The ring body 32 is supported by the elastic connecting member 33 and can move toward the bottom side under the push of the guide cylinder portion 313 to drive the locking member 4 to swing from the locking position to the unlocking position through the elastic connecting member 33 .

[0117] Since the elastic connector 33 can produce elastic deformation, the ring body 32 can be reciprocated up and down. Specifically, when the guide cylinder 313 is not in contact with the ring body 32, or the guide cylinder 313 is in contact with the ring body 32 but does not apply an action force to the ring body 32, the action force applied by the elastic connector 33 to the ring body 32 has at least an upward component to overcome the gravity of the ring body 32 and support the ring body 32 in a suspended position, so that the ring body 32 has a downward movement stroke.

[0118] It should be noted that when the pressing member 31 is in the initial position, the bottom end of the guide cylinder portion 313 and the top end of the ring body 32 may be in contact with each other, or may not be in contact with each other, that is, there is a distance between them along the height direction.

[0119] In this embodiment, when the pressing member 31 moves toward the bottom side under the action of external force, the guide cylinder portion 313 pushes the ring body 32 to move toward the bottom side, and the guide cylinder portion 313 drives the elastic connecting member 33 to move downward, and the locking member 4 moves downward together with the portion connected to the elastic connecting member 33, so that the locking member 4 swings upward away from the end of the elastic connecting member 33, and is retracted into the avoidance opening 12c, thereby realizing the switching of the locking member 4 from the locked position to the unlocked position.

[0120] When the external force is removed, or the external force is reduced so that the force of the elastic member 34 can overcome the external force, the pressing member 31 moves upward under the action of the elastic member 34 and returns to the initial position, while the ring body 32 moves upward under the action of the elastic connecting member 33 and returns to the initial position. When the ring body 32 moves upward, the end of the locking member 4 away from the elastic connecting member 33 swings downward, thereby extending outward from the avoidance opening 12c, thereby switching from the unlocked position to the locked position.

[0121] The number of the locking members 4 is not limited, and may be one or more.

[0122] Each locking member 4 corresponds to an elastic connecting member 33 and a locking groove 2a.

[0123] For example, see Figure 7 The number of the locking members 4 and the elastic connecting members 33 are both multiple, each locking member 4 is connected to the same ring body 32 through the corresponding elastic connecting member 33, and the multiple locking members 4 are arranged at intervals along the circumference of the ring body 32. Correspondingly, the number of the locking grooves 2a is also multiple, and the multiple locking grooves 2a are arranged at intervals around the circumference of the stirring rod 2. In this embodiment, the force uniformity and reliability of the stirring rod 2 can be improved.

[0124] The specific type of the elastic connecting member 33 is not limited, for example, it can be a compression spring.

[0125] The pressing member 31 may be an integrated structure or may be composed of multiple parts connected together, which is not limited here.

[0126] For example, see Fig.10 The stirring rod 2 has a contact portion 21 inside. The contact portion 21 is used to contact the top end of the driving mechanism 3. When the stirring rod 2 is in the installation position, please refer to Fig.12 The stirring rod 2 is supported on the driving mechanism 3 by the abutment portion 21, and the groove wall 2a' on the top side of the locking groove 2a is spaced apart from the locking member 4 in the height direction, so that the stirring rod 2 can move downward under the action of an external force to push at least part of the structure of the driving mechanism 3 to move downward, thereby driving the locking member 4 from the locking position ( Fig.11 and 12 shown) to the unlocked position ( Fig.13 , Fig.14 and 15 shown).

[0127] In this embodiment, when the user needs to unlock the stirring rod 2 , the user presses the stirring rod 2 downward to unlock the locking member 4 .

[0128] For example, see Fig. 9 and Fig.10 The side wall of the stirring rod 2 is also provided with a connecting groove 2b, one end of which is connected to one side of the locking groove 2a along the circumferential direction, and the other end of which passes through the bottom edge of the stirring rod 2. In this way, the locking member 4 can enter and / or exit the locking groove 2a through the connecting groove 2b.

[0129] When the stirring rod 2 needs to be installed on the mounting seat 12, the connecting groove 2b is aligned with the position of the locking member 4 along the circumferential direction, the stirring rod 2 is pushed downward so that the locking member 4 enters the connecting groove 2b, and then the stirring rod 2 is rotated so that the locking member 4 enters the locking groove 2a.

[0130] Specifically, Fig.11 and Fig.12 In the embodiment, the stirring rod 2 is in the installation position. When the stirring rod 2 needs to be removed from the mounting seat 12, the stirring rod 2 is pressed downward, and the stirring rod 2 pushes the driving mechanism 3, thereby causing the locking member 4 to exit the locking groove 2a. At this time, the stirring rod 2 is removed from the mounting seat 12. Fig.11 and Fig.12 The displayed position switches to Fig.14 and Fig.15 At this time, the stirring rod 2 is rotated in the first direction while the stirring rod 2 is kept pressed, so that the locking member 4 enters the connecting groove 2b. At this time, the stirring rod 2 is moved from Fig.14 and Fig.15The displayed position switches to Fig.16 The stirring rod 2 is then lifted upward to remove it. It should be noted that, in the process of lifting the stirring rod 2 upward, even if the locking member 4 extends from the avoidance opening 12c to the connecting groove 2b, since the connecting groove 2b passes through the bottom edge of the stirring rod 2, the locking member 4 will not interfere with the stirring rod 2, so the stirring rod 2 can be removed smoothly.

[0131] It can be understood that, during the process of removing the stirring rod 2, if the stirring rod 2 is rotated in the second direction while being pressed, so that the inner wall of the stirring rod 2 blocks the avoidance opening 12c, during the process of lifting the stirring rod 2 upward, even if the locking member 4 tends to extend from the avoidance opening 12c, the locking member 4 is abutted against the inner wall of the stirring rod 2 and the two slide relative to each other, and the locking member 4 will not block the stirring rod 2 from moving upward, thereby allowing the stirring rod 2 to be smoothly removed.

[0132] It should be noted that the first direction and the second direction are opposite.

[0133] It should be noted that the rotatable angle of the stirring rod 2 may be limited, for example, not exceeding a central angle of 30°.

[0134] For example, see Figure 5 and Figure 6 The top end of the driving mechanism 3 has a convex surface 311a, and the convex surface 311a protrudes toward the abutting portion 21. For example, in an embodiment with a cover portion 311, the outer surface of the cover portion 311 is the convex surface 311a.

[0135] See also Fig.10 The contact portion 21 has a concave surface 21a. The convex surface 311a is matched with the concave surface 21a. In this way, the two can be more reliably contacted and not easy to slip, thereby improving the contact reliability and stability of the stirring rod 2 and the pressing member 31.

[0136] It should be noted that the concave surface 21 a may be a continuous surface, or may be a discontinuous abstract concave surface 21 a defined by ribs, grids, and the like.

[0137] The convex surface 311 a may be a continuous surface, or may be a discontinuous abstract convex surface 311 a defined by ribs, a grid, or the like.

[0138] For example, one of the inner wall of the stirring rod 2 and the outer wall of the mounting seat 12 is provided with a guide rail, and the other is provided with a guide groove, and the guide rail and the guide groove are slidably matched along the height direction. In this way, it is convenient to position the stirring rod 2 when inserting the stirring rod 2, and to guide the movement of the stirring rod 2 during the movement of the stirring rod.

[0139] It should be noted that at least when the stirring rod 2 moves downward to the limit position, Fig.13 , Fig.14 and Fig.15 In the position shown, the guide rail and the guide groove are disengaged, so that the guide rail and the guide groove do not affect the rotation of the stirring rod 2 in this position.
