[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0041] In the description of this application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of this application; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.
[0042] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0043] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.
[0044] See also Figures 1 to 7 As shown, according to an embodiment of the present application, a drum washing machine lifting assembly includes:
[0045] The lifting ribs are provided on the inner wall of the inner drum 2 of the drum washing machine and extend along the axial direction of the inner drum 2;
[0046] The cross section of the lifting rib is set to be crescent-shaped and is bent toward the rotation direction of the drum washing machine.
[0047] The present application provides crescent-shaped lifting ribs on the inner wall to increase the lifting effect on clothes, thereby improving the washing effect of the drum washing machine.
[0048] The lifting ribs are crescent-shaped, with the crescent 1 curved toward the direction of the drum washing machine's rotation. This means that during rotation, the curved crescent 1 scoops up clothing, lifting it to a certain height before releasing it from the ribs. This curved structure significantly enhances the lifting effect of traditional lifting ribs, allowing clothing to be dropped from a higher position for enhanced washing efficiency.
[0049] The lifting ribs are cast from soft rubber or soft plastic, which will not damage clothes.
[0050] The center angle of the crescent 1 is preferably 90°-110°, and one end of the crescent 1 abuts against the inner wall. With the above angle, the clothes can be held and lifted effectively.
[0051] In some embodiments,
[0052] The length of the lifting rib along the radial direction of the inner cylinder 2 is set to L, and the radius of the inner cylinder 2 is set to r, satisfying L / r=0.3-0.45.
[0053] The radial length of the lifting ribs is also an important factor in lifting clothes, but this length is related to the size of the inner drum 2 of the washing machine. The present application sets a proportional relationship between the length of the lifting ribs in this direction and the radius of the inner drum 2, which can ensure that the clothes are lifted to the highest point before they fall off, and are thrown most effectively, so that the washing effect is in the best state.
[0054] Furthermore, this length limitation will not affect the placement of clothes, nor will it change the rated capacity or rated load of the washing machine.
[0055] In some embodiments,
[0056] The crescent shape includes two crescents 1, which are distributed along the circumference of the inner tube 2, symmetrically arranged in the radial direction of the inner tube 2, and bent to both sides respectively.
[0057] Based on the fact that during the washing process of a drum washing machine, its rotation direction alternates between forward and reverse directions regularly, the present application sets the crescent shape as two crescents 1 distributed along the circumferential direction of the inner drum 2, and sets them in radial symmetry and bends to both sides respectively. In this way, no matter how the rotation direction of the inner drum 2 changes, there will be crescents 1 to lift the clothes and improve the washing effect.
[0058] Here, the crescent 1 refers to a curved arc, which may have an uneven thickness or a uniform thickness.
[0059] In some embodiments,
[0060] The two crescents 1 are spaced apart and are respectively arranged on both sides of the mounting boss 3 ; the lifting ribs are mounted on the inner wall through the mounting boss 3 .
[0061] When the specific structure of the two crescents 1 is set, the two crescents 1 are respectively set on the opposite sides of the mounting boss 3. More specifically, the two crescents 1 are set on the two side surfaces of the mounting boss 3 along the circumference of the inner tube 2; and the mounting boss 3 is assembled on the inner wall of the inner tube 2.
[0062] The mounting boss 3 may also be made of soft rubber or soft plastic material, so that it can be made integrally with the crescent 1, which is convenient for assembly and production.
[0063] In some embodiments,
[0064] The two side surfaces of the mounting boss 3 along the axial direction are configured as inclined surfaces 32 , and the cross-sectional area of the mounting boss 3 along the direction toward the center line of the inner tube 2 is configured to be gradually reduced.
[0065] The two side surfaces of the mounting boss 3 in the circumferential direction are respectively connected to two crescents 1, while the two side surfaces in the axial direction are set as inclined surfaces 32. The two inclined surfaces 32 are inclined and close to each other in the direction of the center line of the inner drum 2, and can also be set symmetrically. The purpose is to prevent the discharge of washing water from being blocked during the dehydration process. The inclined surfaces 32 can guide the washing water to flow smoothly to the inner wall surface of the inner drum 2 and flow away through the drainage holes on the inner wall. At the same time, the inclined surface 32 structure can reduce the material and weight of the mounting boss 3, thereby reducing the load on the washing drum motor.
[0066] In some embodiments,
[0067] A clamping member 31 is provided on the side of the mounting boss 3 away from the center line, and a clamping groove 21 is provided on the inner wall. The clamping member 31 is matched with the clamping groove 21 for snap connection.
[0068] The connection method between the mounting boss 3 and the inner tube 2 can be a snap connection. Specifically, a snap-fitting part 31 is provided on the side of the mounting boss 3 away from the center line, and a slot 21 is provided on the inner wall. The snap-fitting part 31 is inserted into the corresponding slot 21 to achieve a quick connection between the two. The structure is stable and the installation is convenient.
[0069] The mounting boss 3 and the clamping member 31 can be made of soft rubber or soft plastic. Therefore, the size of the clamping member 31 can be larger than that of the slot 21 . The clamping member 31 is deformed by squeezing and then installed in the slot 21 .
[0070] In some embodiments,
[0071] A plurality of protrusions 11 are provided on the inner side surface of the crescent 1 , and the plurality of protrusions 11 are arranged and staggered.
[0072] The crescent 1 lifts the clothes, and the clothes mainly contact the inner side of the crescent 1. The present application provides a protrusion 11 on the inner side, which can further increase the friction between the lifting ribs and the clothes, thereby increasing the lifting effect of the lifting ribs on the clothes.
[0073] The protrusion 11 can be configured as a hemispherical shape, and the hemispherical shape can be a solid or hollow structure.
[0074] In some embodiments,
[0075] A plurality of protrusions 12 are provided on the side of the crescent 1 facing the interior of the inner tube 2 .
[0076] A protrusion 12 is provided on the side of the crescent 1 facing the inside of the inner drum 2, the purpose of which is to increase the lifting efficiency of the lifting ribs. Secondly, due to the rubber material, this design further simulates the state of human hands, which is close to hand washing and increases the washing effect of the drum washing machine.
[0077] In some embodiments,
[0078] There are 2-3 lifting ribs, which are evenly distributed along the circumference of the inner wall.
[0079] 2-3 lifting ribs evenly distributed in the circumferential direction are provided on the inner wall of the inner drum 2 to achieve the best lifting and washing effect.
[0080] According to another aspect of the present application, a drum washing machine is provided, comprising the drum washing machine lifting assembly as described above.
[0081] The main washing method of a drum washing machine is to lift the clothes to a high position by relying on the lifting ribs on the inner wall. Then the clothes are thrown and tumbled, and the friction between the clothes is combined to achieve the purpose of washing. Therefore, the lifting height of the lifting ribs is an important indicator of the washing effect of the drum washing machine. This application adopts a crescent-shaped lifting rib structure. The curved surface structure of the crescent 1 can greatly improve the lifting effect of the clothes.
[0082] Combine Figures 1 to 4 As shown, the drum washing machine of the present application lifts the clothes through the curved surface of the double crescent 1. Since the crescent 1 has a concave curved surface structure, the lifting effect on the clothes is much greater than that of a flat surface or other inclined surface 32. In addition, the protrusions 11 are staggered and evenly distributed on the concave curved surface. This increases the friction between the lifting ribs and the clothes, plays a kneading role, and prevents the clothes from easily falling off the lifting ribs. Relatively speaking, the lifting efficiency is improved.
[0083] At the same time, the lifting ribs of the present application can be formed by integrally casting rubber, and the edges and corners of the lifting ribs are rounded. This material and rounded corner treatment allow the lifting ribs to lift clothes during the washing process of the drum washing machine without threatening to damage clothes made of special materials (fragile clothes), thereby protecting the user's clothes to a certain extent.
[0084] The mounting boss 3 structure between the double crescents 1 has a circumferential projection surface that is much smaller than the crescent 1, which is equivalent to the mounting boss 3 being sandwiched between the two crescents 1. Therefore, the two radial side surfaces of the mounting boss 3 are set as inclined surfaces 32 to form an inclined platform-type groove. The purpose is to prevent the washing water from being blocked from being discharged smoothly during the dehydration process. The inclined surface 32 can guide the washing water to flow smoothly along the inclined surface 32 to the drum surface and flow out through the drainage holes on the drum surface. At the same time, the opening of the groove also reduces the mass to a certain extent, thereby reducing the load on the motor.
[0085] Protrusions 12 are set on the sides of the two crescents 1 away from the inner wall. The purpose is to increase the lifting efficiency of the lifting ribs. The protrusions 12 are made of rubber. This design simulates the state of human hands, making washing close to hand washing, thereby increasing the washing effect of the drum washing machine.
[0086] Figure 6 and Figure 7 The figure shows a cross-sectional view of the assembly of the lifting ribs and the inner cylinder 2. The lifting ribs and the inner cylinder 2 are mounted using a snap-fit mechanism. The clips 31 on the bottom of the lifting ribs snap into the mounting grooves on the inner cylinder 2, securing the ribs and facilitating installation. Because the lifting ribs can be made of soft rubber, they are also easy to assemble and disassemble. The number of lifting ribs within the inner cylinder 2 is preferably 2-3, evenly distributed along the circumference. Those skilled in the art will readily appreciate that the above embodiments can be freely combined and superimposed, provided they do not conflict.
[0087] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application. The above description is merely a preferred embodiment of the present application. It should be noted that those skilled in the art can make various improvements and variations without departing from the technical principles of the present application, and such improvements and variations shall also be considered within the scope of protection of the present application.
