[0003] During the washing process, small items such as socks can easily get stuck in the gap between the extension and the inner drum, or even stay inside, affecting the washing effect. Utility Model Content
[0004] The purpose of the present application is to disclose an inner drum assembly and a washing machine.
[0005] In a first aspect, the present application discloses an inner barrel assembly, which includes an inner barrel and a protrusion, wherein the protrusion is arranged at a barrel opening at the front of the inner barrel, and the protrusion is at least partially located in the barrel opening.
[0006] In some embodiments, there are multiple protrusions, which are evenly distributed along the circumference of the barrel mouth.
[0007] In some embodiments, the protrusion includes a protrusion front portion, and adjacent side surfaces of the protrusion front portion are connected by a curved surface.
[0008] In some embodiments, the protrusion is arched along a radial cross section of the inner cylinder.
[0009] In some embodiments, the protrusion includes a protrusion front end surface, a protrusion top surface, and a connecting surface, the connecting surface is connected to the protrusion front end surface and the protrusion top surface, and the connecting surface is upturned relative to a horizontal plane.
[0010] In some embodiments, the inner cylinder includes a cylinder body and a cylinder ring, the cylinder body is assembled with the cylinder ring, and the protrusion is arranged on the cylinder ring.
[0011] In some embodiments, the inner cylinder assembly includes a lifting rib disposed inside the inner cylinder, and the protrusion is disposed corresponding to the lifting rib.
[0012] In some embodiments, along the circumference of the inner cylinder, the angle at which the protrusion deviates from the lifting rib is a, wherein -10 degrees ≤ a ≤ 10 degrees.
[0013] In a second aspect, the embodiments of the present application disclose a washing machine, which comprises any of the aforementioned inner drum assemblies and a door assembly for opening or closing the inner drum, wherein the door assembly comprises a protruding portion protruding toward the inner drum, and the protrusion is located between the protruding portion and the inner drum.

[0027] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 In the first aspect, the present application discloses an inner cylinder assembly 100. The inner cylinder assembly 100 includes an inner cylinder and a protrusion 2. In the embodiment shown in the figure, the inner cylinder includes a cylinder body 20 and a cylinder ring 1. The cylinder ring 1 is annular, and the shape of the ring is determined according to the shape of the cylinder body 20. The cylinder ring 1 and the cylinder body 20 can be assembled into an inner cylinder by any structure (such as snaps, welding or screws). In order to facilitate the assembly of the cylinder ring 1, a guide mechanism can also be provided between the cylinder body 20 and the cylinder ring 1, and the cylinder ring 1 and the cylinder body 20 are assembled with the cooperation of the guide mechanism and the screw or snap structure. The structure of the guide mechanism is not limited, for example, the guide mechanism is a flange.
[0028] The protrusion 2 is arranged at the tube mouth of the front part of the inner tube, and the protrusion 2 is at least partially located in the tube mouth. The front part is the front in the direction facing the door assembly 200, or the part seen by the consumer after opening the door assembly 200 is the front. For the embodiment shown in the figure, because the tube ring 1 is assembled to the cylinder body 20 to form the inner tube, the tube ring 1 can be considered as the tube mouth. In this way, in this way, the protrusion 2 is arranged on the tube ring 1 along the circumference of the tube ring 1, and is at least partially located in the tube ring 1. How to be at least partially located in the ring is not limited, as long as the function described later can be achieved. In the above embodiment, the tube ring 1 and the cylinder body 20 are split structures, and the protrusion 2 can be integrally formed with the tube ring 1, or it can be an independent component installed on the tube ring 1 and protrudes relative to the tube ring 1. Correspondingly, the structure of the protrusion 2 is not limited, as long as the function described later can be achieved.
[0029] In the above embodiment, the barrel ring 1 and the barrel body 20 are separate structures. By setting the protrusion 2 on the barrel ring 1 (for the convenience of the following description, the assembly formed by the barrel ring 1 and the protrusion 2 is called the barrel ring assembly 10), the barrel ring 1 is assembled to the barrel body 20 so that the protrusion 2 is located at the barrel mouth at the front of the inner barrel. The technicians can understand that based on the role of the protrusion 2 described later, the setting of the protrusion 2 is not limited to the embodiment of the present application. For example, the barrel ring 1 can be integrally formed with the barrel body 20 to form the inner barrel. In short, as long as the protrusion 2 is set at the front of the inner barrel, the protrusion 2 plays the role described later.
[0030] In a second aspect, the present application discloses a washing machine. Figure 7 The washing machine includes any one of the inner drum assembly 100 and the door assembly 200 described in the present application. The door assembly 200 is used to open or close the inner drum, whereby, when the door assembly 200 closes the inner drum, the door assembly 200 and the inner drum assembly 100 form a washing space. The door assembly 200 includes an extension 201 protruding toward the barrel 20. The extension 201 is usually made of a transparent material, such as glass. In some embodiments, the extension 201 is a door glass. The protrusion 2 is located between the extension 201 and the barrel 20.
[0031] As set up as above, for the inner drum assembly 100 or the washing machine, since the protrusion 2 is provided, the protrusion 2 is located between the extension 201 and the inner drum, and the protrusion 2 rotates synchronously with the inner drum. Therefore, on the one hand, the protrusion 2 generates turbulence (or water waves) during the rotation process, and these turbulences make it difficult for small clothes such as socks to get stuck in the gap between the extension 201 (door glass) and the inner drum. On the other hand, the protrusion 2 will rub against the small clothes such as socks during the rotation process. Since the protrusion 2 rotates with the inner drum, from the whole process, this friction force produces an effect similar to pulling out, and can pull out small clothes such as socks stuck in the gap between the extension 201 and the inner drum. At least one of the above two aspects avoids the small clothes such as socks getting stuck in the gap between the extension 201 and the inner drum (for example, Figure 6 Middle E area), which improves the washing effect.
[0032] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 There are multiple protrusions 2, which are evenly distributed along the circumference of the barrel mouth (barrel ring 1). Figure 1 , Figure 2 , Figure 3 and Figure 5 Only two protrusions 2 are shown, but the number of protrusions 2 is not limited thereto, and may be three, four, or five, etc. In the case where there are only two protrusions 2, the uniform distribution means that the two protrusions 2 are distributed on a diameter of the barrel ring 1. In other embodiments, there may be only one protrusion 2, which is still located in the barrel mouth (barrel ring 1).
[0033] As configured above, there are multiple protrusions 2, which are evenly distributed along the circumference of the barrel mouth (barrel ring 1), which is also beneficial for the protrusions 2 to generate turbulence and / or rub against small clothes such as socks, thereby avoiding socks and other small clothes from being stuck in the gap between the extension part 201 and the inner barrel, thereby improving the washing effect.
[0034] See also Figure 4 and Figure 1 Combined with Figure 3 and Figure 2, the protrusion 2 includes a protrusion front portion 21, and the adjacent side surfaces of the protrusion front portion 21 are connected by a curved surface 210. The protrusion front portion is a part of the protrusion 2 that can be seen by the consumer when opening the door assembly 200, and is also the part of the protrusion 2 that contacts with small clothing such as socks. In this embodiment, the adjacent side surfaces of the protrusion 2 include a protrusion front end surface 211 facing the consumer, a protrusion top surface 212, a connecting surface 213, a part of the protrusion left side surface 214, and a part of the protrusion right side surface 215, which are connected by the curved surface 210. Of course, the adjacent side surfaces are not limited to this, as long as the protrusion front portion 21 is connected by the curved surface 210 as described later so that there is no sharp part. Of course, the curved surface 210 is not limited to a circular arc surface, and can also be a curved surface composed of wavy concave and convex connected, as long as there is no sharp part in the protrusion front portion 21.
[0035] As set up as above, since the adjacent side surfaces of the raised front portion are connected by the arc surface 210, the arc surface 210 makes the raised front portion 21 have no sharp parts (such as sharp corners), thus preventing small clothing such as socks from being entangled, thereby preventing small clothing such as socks from being torn, etc.
[0036] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The protrusion 2 is arched along the radial cross section of the inner cylinder. This arch can be as follows Figure 5 As shown, it is a hollow arch, or it can be a solid arch. Of course, the arch is not limited to including the connecting surface 213 as shown in the figure, and there can be no connecting surface 213, that is, the existence of the connecting surface 213 makes the protrusion 2 have five corners, and when there is no connecting surface 213, the protrusion 2 has four corners.
[0037] As set above, the protrusion 2 is arched along the radial section of the inner tube, so that the strength of the protrusion 2 is better. In addition, the arch makes the surface of the protrusion 2 curved without sharp parts, thus preventing small clothes such as socks from being entangled.
[0038] See also Figure 4 and Figure 3 Combined with Figure 1 The protrusion 2 includes a protrusion front end surface 211, a protrusion top surface 212 and a connecting surface 213. The connecting surface 213 is connected to the protrusion front end surface 211 and the protrusion top surface 212, and the connecting surface 213 is upturned relative to the horizontal plane.
[0039] As set up as above, since the connecting surface 213 is connected to the protruding front end surface 211 and the protruding top surface 212, and the connecting surface 213 is upturned relative to the horizontal plane, if there is no connecting surface 213, the protruding front end surface 211 and the protruding top surface 212 will intersect at a right angle. In this way, during transportation and the like, the inner tube rotates and the right angle formed by the protruding front end surface 211 and the protruding top surface 212 may collide with the protruding portion 201. Therefore, the connecting surface 213 plays a role of avoiding air, preventing the protrusion 2 from colliding with the protruding portion 201 and damaging the protruding portion 201 (or the glass door).
[0040] See also Figure 1 and Figure 2 Combined with Figure 6 and Figure 7 , the inner tube assembly 100 includes a lifting rib 30 arranged inside the inner tube (in this embodiment, it is arranged inside the barrel 20). In addition, the inner tube assembly 100 also includes a back cover 40 arranged opposite to the barrel ring 1. The protrusion 2 is arranged correspondingly to the lifting rib 30 to jointly disturb the flow. The corresponding arrangement means that the protrusion 2 is located within a certain range of the lifting rib 30 so that the two can jointly disturb the flow. The structure of the lifting rib 30 is not limited, at least it can achieve disturbance (or water waves) and make the clothes move in the inner tube.
[0041] As configured above, since the lifting ribs 30 and the protrusions 2 jointly disturb the flow (or water waves), the flow of water makes it difficult for small clothes such as socks to get stuck between the extension part 201 and the inner drum, thereby improving the washing effect.
[0042] See also Figure 2 In some embodiments, along the circumference of the inner cylinder (which can also be understood as the circumference of the cylinder 20), the angle of the protrusion 2 away from the lifting rib 30 is a, -10 degrees ≤ a ≤ 10 degrees. Figure 2 In the embodiment, a = 0 degrees (the protrusion 2 is directly opposite to the lifting rib 30), that is, the protrusion 2 is within the range of angle a. Of course, if Figure 2 If a is positive in the middle, then, the technician will understand that a is negative in the other direction. Figure 2 Here, the center of the protrusion 2 is used as a reference. In some embodiments, the side of the protrusion 2 may also be used as a reference.
[0043] As set up above, since the angle of the protrusion 2 deviating from the lifting rib 30 along the circumference of the inner drum is a, -10 degrees ≤ a ≤ 10 degrees, the effect of the joint turbulence is better. Combined with the effect of the protrusion 2, small clothes such as socks can be prevented from being stuck between the extension 201 and the inner drum, thereby improving the washing effect.
[0044] See also Figure 6 and Figure 7, on the projection of the axial plane of the inner cylinder, the projection of the protrusion 2 partially overlaps with the projection of the protruding portion 201 . Figure 7 The overlapping portion is indicated as b.
[0045] As set up above, since the projection of the protrusion 2 partially overlaps with the projection of the extension 201, on the one hand, the turbulence (or water waves) generated by the water movement driven by the protrusion 2 can more easily prevent small clothes such as socks from being stuck between the extension 201 and the inner drum. On the other hand, the partial overlap can also make the protrusion 2 produce a pulling effect, thereby preventing small clothes such as socks from being stuck between the extension 201 and the inner drum, and ultimately improving the washing effect.
[0046] See also Figure 6 and Figure 7 The extension 201 shrinks toward the inner tube. There is no limit to how it shrinks. For example, the extension 201 is a flat truncated cone (the axis of the truncated cone is in the horizontal direction) to achieve the shrinkage. This shrinkage is gradual. In other embodiments, based on the effect of subsequent shrinkage, it may not be gradual. In short, after the extension 201 shrinks toward the inner tube, the extension side 2011 of the extension 201 is an inclined surface. The angle of the inclined surface is not limited. Of course, the inclined surface may not be symmetrical like a truncated cone.
[0047] As described above, since the extension 201 shrinks toward the inner tube, the extension side 2011 of the extension 201 is an inclined surface, and combined with the turbulence (or water waves) generated by the protrusion 2 (or the protrusion 2 and the lifting rib 30), small clothes such as socks are more likely to return to the inner tube along the extension side 2011, thereby preventing small clothes such as socks from being stuck between the extension 201 and the inner tube. Of course, as the extension gradually shrinks toward the inner tube, the gradual shrinkage makes the circumference of the extension 201 downward, making it easier for small clothes such as socks to return to the inner tube along the inclined surface.
[0048] The above description is only a preferred implementation mode of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
