Description

TECHNICAL FIELD

[0001] The utility model relates to clothes processing device technical field especially is related to a clothes processing device's drum subassembly and clothes processing device. BACKGROUND

[0002] At present on the market, the lifting rib on the inner side wall of the drum of clothes processing device is generally parallel to the drum axis direction, and the lifting rib has limited lifting effect on the clothes in the circumferential direction and the radial direction. In order to further improve the lifting effect of clothes, some lifting ribs improve the arc surface away from the bottom surface, but the overall lifting rib is still parallel to the drum axis direction, and at the same time, due to the width of the lifting rib along the drum circumferential direction cannot be too large, so the above improvement has limited effect on improving the lifting effect. SUMMARY

[0003] In order to overcome the defects in the prior art, the utility model provides a clothes processing device's drum subassembly and clothes processing device, which has the advantages of lifting in the circumferential direction, radial direction and axial direction of the drum.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A drum subassembly of clothes processing device, comprising a drum and a lifting rib connected to the inner side wall of the drum, the drum has a clothes feeding port and a drum bottom opposite to the clothes feeding port, and the lifting rib comprises:

[0006] A first end face close to the clothes feeding port;

[0007] A second end face close to the drum bottom;

[0008] A first lifting face and a second lifting face for connecting the first end face and the second end face, respectively located on both sides of the drum in the circumferential direction;

[0009] A top face located between the first end face, the second end face, the first lifting face and the second lifting face away from one end of the inner side wall of the drum;

[0010] A bottom face located between the first end face, the second end face, the first lifting face and the second lifting face close to one end of the inner side wall of the drum, and tightly abutting the inner side wall of the drum;

[0011] Wherein, the connecting line between the midpoint of the intersection line of the bottom face and the first end face and the midpoint of the intersection line of the bottom face and the second end face is the installation center line, and the installation center line is crossly arranged with the axis of the drum.

[0012] The midpoint of the intersection line of the bottom surface and the first end surface and the midpoint of the intersection line of the bottom surface and the second end surface are connected to cross the axis of the roller, so that the first end surface and the second end surface of the lifting rib have a certain staggered interval along the circumference of the roller, so that the clothes can be lifted along the axial direction of the roller and the axial lifting effect is obvious while being lifted in the circumferential and radial directions under the action of the first lifting surface or the second lifting surface during the rotation of the roller.

[0013] Optionally, the lifting rib is a straight line.

[0014] By adopting the above technical scheme, the lifting rib is a straight line, and processing is convenient.

[0015] Optionally, the cross section of the lifting rib perpendicular to the length direction of the lifting rib is isosceles trapezoidal, and the width of the top surface is smaller than the width of the bottom surface.

[0016] By adopting the above technical scheme, the cross section of the lifting rib perpendicular to the length direction of the lifting rib is isosceles trapezoidal, and the width of the top surface is smaller than the width of the bottom surface, so that the clothes can be lifted while avoiding excessive friction of the lifting rib to the clothes and affecting the service life of the clothes.

[0017] Optionally, there are at least two lifting ribs in the same direction parallel to the axis of the roller, and the lifting ribs in this direction are arranged in parallel.

[0018] By adopting the above technical scheme, there are at least two lifting ribs in the same direction parallel to the axis of the roller, which can reduce the length of a single lifting rib in the axial direction of the roller, and is conducive to improving the strength and installation stability of the lifting rib.

[0019] Optionally, adjacent lifting ribs in the circumferential direction of the roller are staggered in the axial direction of the roller.

[0020] By adopting the above technical scheme, adjacent lifting ribs in the circumferential direction of the roller are staggered in the axial direction of the roller, so that small clothes can pass through the lifting ribs in the same direction parallel to the axis of the roller during the lifting process and then encounter the adjacent lifting ribs in the circumferential direction of the roller, thereby continuing to be lifted, thereby improving the lifting efficiency.

[0021] Optionally, the first lifting surface and the second lifting surface are the same helical surface.

[0022] By adopting the above technical scheme, the first lifting surface and the second lifting surface are the same helical surface, and the strength of the helical first lifting surface and the second lifting surface is greater than that of the planar first lifting surface and the second lifting surface, so that the staggered interval of the first end surface and the second end surface of the lifting rib in the circumferential direction of the roller can be larger, and the lifting effect of the clothes in the axial direction of the roller is better.

[0023] Optionally, the drum has at least two lifting ribs in the circumferential direction of the drum; the installation center lines of at least two adjacent lifting ribs in the circumferential direction of the drum are opposite in the direction of inclination relative to the axis of the drum.

[0024] By adopting the above technical scheme, since the installation center lines of the two adjacent lifting ribs are opposite in the direction of inclination relative to the axis of the drum, the clothes can move both inward along the axial direction of the drum and outward along the axial direction of the drum during rotation of the drum, so that the clothes lifting effect is better.

[0025] Optionally, the lifting rib is an integral forming structure.

[0026] By adopting the above technical scheme, the integral forming structure of the lifting rib has greater strength and is simple to process.

[0027] A clothes treatment device comprises the above drum assembly.

[0028] By adopting the above technical scheme, the clothes can be lifted and tumbled in the radial direction and the circumferential direction while the clothes are moved in the axial direction of the drum, so that the clothes tumbling effect is improved and the drying or washing efficiency is improved under the condition that the rotation speed of the drum is unchanged.

[0041] The following will be described in detail in combination with the accompanying drawings Figures 1-9 The utility model is further described in detail.

[0042] Embodiment one: a clothes treatment device, referring to Figure 1 and Figure 2 , comprising a drum assembly; the drum assembly comprises a drum 10 and two lifting ribs 20; the front end of the drum 10 is provided with a clothes feeding part 11, the rear end is provided with a drum bottom 13 and a drum wall 12 connecting the clothes feeding part 11 and the drum bottom 13; the clothes feeding part 11 is provided with a clothes feeding port 100; the two lifting ribs 20 are fixed on the inner side wall of the drum wall 12; when the drum 10 is driven, the clothes of the drum 10 is moved in the radial direction, axial direction and axial direction of the drum 10 under the action of the lifting rib 20, so that the clothes tumbling effect is improved, and the drying or washing efficiency is improved.

[0043] Reference Figure 3 and Figure 4The lifting rib 20 comprises a first end surface 21, a second end surface 22, a first lifting surface 23, a second lifting surface 25, a top surface 24 and a bottom surface 26; the first end surface 21 is close to the clothes feeding opening 100; the second end surface 22 is close to the drum bottom 11; the first lifting surface 23 and the second lifting surface 25 connect the first end surface 21 and the second end surface 22 and are respectively located on the two sides of the drum 10 in the circumferential direction; the top surface 24 is located between the ends of the first end surface 21, the second end surface 22, the first lifting surface 23 and the second lifting surface 25 away from the inner side wall of the drum wall 12; the bottom surface 26 is located between the ends of the first end surface 21, the second end surface 22, the first lifting surface 23, the second lifting surface 25 close to the inner side wall of the drum 10 and closely adheres to the inner side wall of the drum wall 12; in order to avoid the lifting rib 20 corner being too sharp to damage the clothes, the edges between the first end surface 21 and the first lifting surface 23 and the second lifting surface 25, the edges between the second end surface 22 and the first lifting surface 23 and the second lifting surface 25, and the corners between the top surface 24 and the first end surface 21, the second end surface 22, the first lifting surface 23 and the second lifting surface 25 are all rounded. The first lifting surface 23 of the lifting rib 20 is located on the side of the lifting rib 20 along the counterclockwise circumferential direction of the drum 10, and the second lifting surface 25 is located on the side of the lifting rib 20 along the clockwise circumferential direction of the drum 10. The top surfaces 24 of the two lifting ribs 20 are located on the same circumferential surface with the axis of the drum 10 as the central axis, and the bottom surfaces 26 are located on the same circumferential surface with the axis of the drum 10 as the central axis.

[0044] With reference to Figure 5 And Figure 6 The midpoint of the intersection line of the bottom surface 26 and the first end surface 21 and the midpoint of the intersection line of the bottom surface 26 and the second end surface are connected to form a mounting center line 27, and the mounting center line 27 is arranged to intersect the axis of the drum 10; the mounting center lines 27 of the two lifting ribs 20 are opposite in inclination direction relative to the axis of the drum 10; in this way, as the drum 10 rotates, the clothes will be lifted radially, circumferentially and axially inwardly along one of the lifting ribs 20 and radially, circumferentially and axially outwardly along the other lifting rib 20, so that the clothes lifting effect is good, the tumbling effect is good, and the drying or washing efficiency is improved.

[0045] With reference to Figure 3 And Figure 4 The first lifting surface 23 and the second lifting surface 25 of the same lifting rib 20 are the same helical surface; the first lifting surface 23 and the second lifting surface 25 of one lifting rib 20 are left-handed helical surfaces with the first end surface 21 as the starting point; the first lifting surface 23 and the second lifting surface 25 of the other lifting rib 20 are right-handed helical surfaces with the first end surface 21 as the starting point. The helical surface has greater strength relative to the plane, so the offset distance of the first end surface 21 and the second end surface 22 of the lifting rib 20 in the circumferential direction of the drum 10 can be designed to be larger, and the lifting effect of the clothes in the axial direction of the drum is better.

[0046] Referring to Figure 3 and Figure 4 The lifting rib 20 is made of plastic and is integrally cast; the lifting rib 20 is a plastic shell open to the bottom surface 26, which effectively reduces the weight of the lifting rib 20 and reduces the load while ensuring strength; in order to facilitate the fixation of the lifting rib 20 to the drum 10, a pair of internally threaded columns are formed in the opening of the lifting rib 20, the internally threaded columns are arranged along the radial direction of the drum 10, and a pair of radial perforations that cooperate with the internally threaded columns are formed on the drum wall 12; when the lifting rib 20 is connected to the drum 10, the self-tapping bolts are screwed through the radial perforations and onto the internally threaded columns, which facilitates installation. In addition, in order to increase the strength of the internally threaded columns, a plurality of reinforcing ribs are formed between the internally threaded columns and the sidewalls of the opening of the lifting rib 20.

[0047] Referring to Figure 5 and Figure 6 In order to increase the working area of the lifting rib 20, the distance between the first end surface 21 and the front end of the drum wall 12 and the distance between the second end surface 22 and the rear end of the drum wall 12 are as small as possible to avoid small clothes from falling off the front and rear sides of the lifting rib 20 during the lifting process, which affects the lifting effect.

[0048] In other embodiments, the drum assembly has three or more lifting ribs 20, wherein as long as the installation center lines 27 of any two adjacent lifting ribs 20 are opposite in the direction of inclination relative to the axis of the drum 10, the clothes can achieve axial inward and axial outward lifting movement; wherein the lifting effect is best when the total number of lifting ribs 20 is even, and the installation center lines 27 of any two adjacent lifting ribs 20 are opposite in the direction of inclination relative to the axis of the drum 10.

[0049] Embodiment two: The difference between embodiment two and embodiment one is that referring to Figures 7-9 The first lifting surface 23 and the second lifting surface 25 are not helical surfaces but are flat surfaces, so that the entire lifting rib 20 is in the shape of a straight line. In order to avoid excessive friction of the lifting rib 20 on the clothes and affect the service life of the clothes, the cross section of the lifting rib 20 perpendicular to its length direction is in the shape of an isosceles trapezoid and the width of the top surface 24 is smaller than the width of the bottom surface 26.

[0050] Referring to Figure 7 and Figure 8 Since the flat surface has relatively small strength compared to the helical surface, the length of the straight line-shaped lifting rib 20 will not be as long as that of the lifting rib 20 in embodiment one, and in order to increase the maximum axial lifting distance in the axial direction of the drum 10, there are at least two lifting ribs 20 in the same direction parallel to the axis of the drum 10 and the lifting ribs 20 in this direction are arranged parallel to each other, which compensates for the shortening of the overall length of the straight line-shaped lifting rib 20 due to the requirement of strength.

[0051] Reference Figure 7 and Figure 8 Since the multiple lifting ribs 20 are in the same direction parallel to the axis of the drum 10, the gap between the adjacent lifting ribs 20 in this direction is inevitable, because too many lifting ribs 20 in the same direction parallel to the axis of the drum 10 will increase the load of the drum 10 and affect the working space in the drum 10, and since the gap between the lifting ribs 20 in this direction exists, small clothes will fall from the gap during lifting, thereby affecting the lifting efficiency; therefore, the adjacent lifting ribs 20 in the circumferential direction of the drum 20 are staggered in the axial direction of the drum, so that the clothes falling from the above gap will be lifted again under the action of the adjacent lifting ribs 20 in the circumferential direction of the drum 20; in addition, in order to further improve the efficiency, the end of the lifting rib 20 overlaps the end of the adjacent lifting rib 20 in the circumferential direction of the drum 20 in the axial direction, so that the situation that small clothes cannot be lifted because they cannot touch the lifting rib 20 during falling is avoided.

[0052] Since the length of the lifting rib 20 in this embodiment is not very large, the opening on the bottom surface 26 can be like the lifting rib 20 in embodiment one, and of course the lifting rib 20 can also be a solid entity.

[0053] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
