Description

Technical Field

[0001] The present invention belongs to the technical field of household appliances, and more specifically, relates to a barrel assembly and a laundry treatment device. Background Art

[0002] A laundry treatment device has a cavity for accommodating clothes. A water guiding device can be arranged in the cavity. The water guiding device guides water flow from the cavity into a channel in the water guiding device, and guides the water flow to flow upward through the channel to the outlet of the water guiding device, and sprays the water flow from the outlet into the cavity. Through the guiding and spraying effects of the water guiding device, the cleanliness of the washing process is improved. However, in related laundry treatment devices, the water flow intensity in the water guiding device is small, and thus the intensity of the sprayed water flow is also small, which affects the washing quality.

[0011] In some embodiments, the second sub-protruding portion is adjacent to the body of the wave disc in the radial direction, and the radial edge of the second sub-protruding portion is arranged in a circle.

[0012] In some embodiments, a plurality of the blades are circumferentially spaced apart, the plurality of blades are arranged radially, and each blade is arranged in an arc shape and the bending directions of each arc are the same.

[0014] In some embodiments, the first channel is used to divert water from the water inlet to the cavity of the washing tub when the wave disc rotates forward; the second channel is used to divert water from the water inlet to the cavity of the washing tub when the wave disc rotates reverse.

[0015] In some embodiments, it further includes: a filter, and the filter covers the water outlet of the second channel.

[0033] An embodiment of the present invention provides a barrel assembly and a laundry treatment device. The laundry treatment device may be a washing machine with a washing function or a washing and drying integrated machine with washing and drying functions. Hereinafter, a single-tub washing machine with an open top will be taken as an example for illustration.

[0034] As Figure 1 and Figure 2 shown, the barrel assembly includes a washing barrel 1 and a wave disc 2. The washing barrel 1 has a cavity 11 extending axially ( Figure 1 the up and down direction shown).

[0035] As Figure 1 shown, taking the axial direction of the washing barrel 1 being arranged vertically ( Figure 1 the up and down direction shown) as an example for illustration. One end ( Figure 1 the lower end shown) of the washing barrel 1 in the axial direction closes the cavity 11, and the other end ( Figure 1 the upper end shown) of the washing barrel 1 in the axial direction is open. The open end can communicate with both the inside and outside of the cavity 11, and the user can take in and out clothes from the opening into the cavity 11.

[0036] As Figure 2 shown, the wave disc 2 is arranged in the cavity 11. The wave disc 2 is arranged closer to the closed end of the cavity 11 relative to the open end of the cavity 11. It can be understood that the wave disc 2 is located at a position close to the bottom in the washing barrel 1. The wave disc 2 is axially connected to the washing barrel 1. That is to say, the wave disc 2 is relatively fixed to the washing barrel 1 axially, and the wave disc 2 cannot move axially relative to the washing barrel 1, but the wave disc 2 can move circumferentially relative to the washing barrel 1. For example, the wave disc 2 can rotate around the axis relative to the washing barrel 1. Among them, the wave disc 2 can rotate clockwise or counterclockwise around the axis of the washing barrel 1. The embodiment of the present invention does not limit the direction in which the wave disc 2 can rotate. Among them, the wave disc 2 and the washing barrel 1 may be coaxially arranged, and both the wave disc 2 and the washing barrel 1 can be regarded as axisymmetric structures. The above-mentioned axial direction is the axis direction of the wave disc 2 and the washing barrel 1.

[0037] As Figure 2 shown, the wave disc 2 includes a body 21 and blades 22 arranged on the surface of the body 21. The body 21 may be a disc-shaped structure. However, the body 21 is not a circular disc. It can be understood that as Figure 2As shown in the figure, the upper surface of the main body 21 is wavy, which is conducive to contacting and rubbing with the clothes during the washing process. The main body 21 can be an axisymmetric structure, and a groove can be provided at its axisymmetric center for facilitating the connection with the washing tub 1. A number of blades 22 are provided at intervals on the lower surface of the main body 21. Among them, the blades 22 can be radial, extending from a position close to the axisymmetric center of the main body 21 to the edge or near the edge of the main body 21, and the extending direction of the blades 22 can be the radial direction of the main body 21.

[0038] Among them, the main body 21 is axially connected to the washing tub 1. It should be noted that the connection method between the main body 21 and the washing tub 1 in the embodiments of the present invention includes direct connection and indirect connection. That is to say, the main body 21 can be directly in contact with the washing tub 1 for connection. Of course, the main body 21 can also be connected to a clutch, and the clutch is arranged outside the washing tub 1, and the clutch can drive the main body 21 to rotate relative to the washing tub 1. The above connection methods can also represent the axial connection between the main body 21 and the washing tub 1. The blades 22 are located between the main body 21 and the washing tub 1. The space between the main body 21 and the washing tub 1 refers to the space formed between the bottom ( Figure 2 the lower part shown in the figure) of the washing tub 1 and the main body 21. The main body 21 can extend approximately along the radial direction of the washing tub 1 ( Figure 1 and Figure 2 the left and right directions shown in the figure). The radial direction refers to the direction perpendicular to the axial direction of the washing tub 1. The main body 21 can roughly divide the cavity 11 of the washing tub 1 into two sub-cavities axially ( Figure 2 the up and down direction), namely a washing cavity 111 and a water passing cavity 112. The washing cavity 111 is located on the side close to the opening of the washing tub 1 ( Figure 2 the upper side shown in the figure), and the water passing cavity 112 is located on the side close to the closed side of the washing tub 1 ( Figure 2 the lower side described). Then the blades 22 are located in the water passing cavity 112 rather than the washing cavity 111. Among them, the washing cavity 111 can be used to accommodate the clothes to be washed, and the water passing cavity 112 can communicate with the washing cavity 111 to realize the circulation of the liquid between the washing cavity 111 and the water passing cavity 112. That is to say, a water passing hole 211 can be provided on the main body 21 so that the liquid between the washing cavity 111 and the water passing cavity 112 can flow through each other. However, the aperture of the water passing hole 211 is relatively small, so that while the water passing hole 211 can conduct the liquid, it can also isolate the clothes in the washing cavity 111 so that the clothes will not enter the water passing cavity 112.

[0039] As Figure 2 shown in the figure, an inlet 23 is formed between the wave disk 2 and the washing tub 1, and the size of the inlet 23 is larger than the size of the water passing hole 211. It should be noted that the inlet 23 can be formed on the main body 21, or can be formed on the washing tub 1, or the inlet 23 can be jointly formed by the main body 21 and the washing tub 1.

[0040] Combined Figure 3 As shown, a gap is formed between the outer edge 22a of the blade 22 and the continuous edge 131 of the washing tub 1; it can be understood that the wave disc 2 is arranged inside the washing tub 1, the blade 22 is the lower part of the wave disc 2, and there is a gap between the blade 22 and the washing tub 1. This gap is the gap between the edge of the blade 22 far from the symmetry axis center of the body (i.e., the outer edge 22a) and the edge of the washing tub 1 closest to the symmetry axis center of the body 21 (i.e., the continuous edge 131). This gap forms a flow channel before the water flows into the water inlet 23. The continuous edge 131 described in the embodiment of the present invention refers to the edge of the washing tub 1 closest to the symmetry axis center of the body 21, and the slopes of all points on the continuous edge 131 change continuously and do not have sudden change values. The water inlet 23 can be formed inside the washing tub 1. At the position of the water inlet 23, the continuous edge 131 is interrupted. For example, when one water inlet is provided in the same washing tub, the washing tub has a continuous continuous edge along the circumference; as Figure 3 shown, when two water inlets 23 are provided on the same washing tub, the two water inlets 23 can divide the circumferential contour of the washing tub into two continuous continuous edges 131. The two continuous edges 131 are not continuous with each other, but all points on the same continuous edge 131 are continuous with each other; in other embodiments, when n water inlets are provided on the washing tub, the circumferential contour of the washing tub has n continuous edges.

[0041] As Figure 3 shown, there are multiple blades 22, and correspondingly, there are multiple outer edges 22a. The positions of the outer edges 22a of the multiple blades 22 form a dotted line. Therefore, the above-mentioned gap can be approximately represented by the space between the dotted line and the continuous edge 131 of the washing tub 1. L represents the radial distance between the outer edge 22a of the blade 22 and the continuous edge 131 of the washing tub 1, that is, the length of the gap in the radial direction. The radial distance L of the same continuous edge 131 changes monotonically in the extending direction of the continuous edge ( Figure 3 shown circumferentially), and the radial distance L of the continuous edge 131 in the extending direction of the continuous edge can be monotonically increasing or monotonically decreasing. As Figure 3 shown, the radial distance between the left continuous edge and the outer edge of the blade increases monotonically in the clockwise direction, and the radial distance between the right continuous edge and the outer edge of the blade also increases monotonically in the clockwise direction; in the counterclockwise direction, the radial distances between the left and right continuous edges and the outer edge of the blade both decrease monotonically.

[0042] Combined Figure 2 and Figure 3As shown, during the rotation of the wave disk 2, the blade 22 can rotate around the axial direction. The liquid in the water passage cavity 112 can follow the rotation of the blade 22 under the disturbance of the blade 22. At the same time, the liquid moves towards the outer periphery of the wave disk 2 under the action of centrifugal force. The liquid will move into the gap between the outer edge 22a of the blade 22 and the continuous edge 131 of the washing tub 1 and flow to the water inlet 23. As Figure 3 shown, when the blade 22 rotates clockwise (forward rotation with the rotation direction consistent with the bending direction of the blade), the liquid in the water passage cavity 112 where the blade 22 is located is also driven to rotate clockwise and flows in the gap between the outer edge 22a of the blade 22 and the continuous edge 131 of the washing tub 1 due to the action of centrifugal force, that is, the liquid flows into the water inlet clockwise through the gap. The gap can be regarded as the flow channel of the liquid. In the extending direction of each continuous edge 131, the radial length L of the gap increases towards the direction close to the water inlet 23. For example, Figure 3 shown, the water flow flows from bottom to top along the left continuous edge 131 in the figure into the left flow channel of the water inlet 23 above in the figure, and the water flow flows from top to bottom along the right continuous edge 131 in the figure into the right flow channel of the water inlet 23 below in the figure. During the flowing process, the gap becomes wider and the cross-sectional area of the flow channel increases. According to Bernoulli's principle, the liquid flow velocity decreases and the static pressure of the liquid increases. Then the water pressure is relatively high when the liquid reaches the water inlet.

[0043] The barrel assembly provided by the embodiment of the present invention includes a washing tub and a wave disk. A cavity is provided in the washing tub. The radial distance between the continuous edges of the wave disk arranged in the cavity monotonically changes in the extending direction of the continuous edges, and the wave disk can rotate around the axial direction of the washing tub. The wave disk includes a body and blades. The blades are located between the body and the washing tub. An inlet is formed between the wave disk and the washing tub. The radial distance between the outer edge of the blade and the continuous edge of the washing tub monotonically changes in the extending direction of the continuous edge, so that the water pressure at the inlet can be relatively high.

[0044] In some embodiments, as Figure 1 shown, the washing tub includes a barrel body 12 and a base body 13. A cavity 11 is provided in the barrel body 12. One end of the barrel body 12 in the axial direction ( Figure 1 the upper end shown) is open, and the other end of the barrel body 12 in the axial direction ( Figure 1 the lower end described) is a closed end 12a. The base body 13 is arranged in the cavity 11 and is adjacent to the closed end 12a of the cavity 11. The base body 13 is fixedly connected to the barrel body 12.

[0045] As Figure 2 shown, the base body 13 can be regarded as an annular structure. The inside of the base body 13 is hollow, and the hollow part can form a water passage cavity 112 with the body 21. The blade 22 is located between the body 21 and the base body 13. As Figure 3As shown, a gap is formed between the outer edge 22a of the blade 22 and the continuous edge 131 of the seat body 13. In the embodiment of the present invention, by setting the washing tub as a barrel body and a seat body, the barrel body and the seat body can be processed separately, so that the change in the gap between the outer edge of the blade and the continuous edge of the seat body can be obtained by directly machining the outer contour of the seat body, reducing the processing difficulty of the washing tub and improving the processing efficiency.

[0046] In some embodiments, as Figure 3 shown, in the elevation view perpendicular to the axial direction, Figure 3 the axis in Figure 3 is in the direction perpendicular to the paper surface. The outer edge 22a of the blade 22 is located on the circumference ( Figure 3 the dotted line shown). In the embodiment of the present invention, the blades 22 are radially arranged on the body 21, and the blades 22 have equal lengths in the radial direction, so that the outer edges 22a of the blades 22 are located on the same circumference ( Figure 3 the dotted line shown). The continuous edge 131 of the seat body 13 is arranged in an Archimedean spiral. It should be noted that the Archimedean spiral represents the trajectory generated when a point moves away from a fixed point at a uniform speed while rotating around the fixed point at a fixed angular velocity. When the circumferential speed and the linear speed both increase by a factor of two, the shape of the Archimedean spiral does not change. Therefore, the Archimedean spiral belongs to an equal speed ratio spiral, and at the same time, since it expands equidistantly in each rotation period, it can also be called an equidistant spiral. In the embodiment of the present invention, the continuous edge of the seat body is arranged according to the changing trend of the Archimedean spiral, and the outer edges of multiple blades are all located on the same circumference, so that the radial spacing L of the gap formed between the outer edge of the blade and the continuous edge of the seat body monotonically changes in the extending direction of the continuous edge 131. When the water flow direction is consistent with the gap increasing direction, the gap gradually increases in the direction towards the water inlet, and the effect that the water pressure gradually increases during the process of the water flow flowing towards the water inlet can be achieved.

[0047] In some embodiments, as Figure 3 shown, there are multiple water inlets 23, that is, multiple water inlets 23 are arranged circumferentially on the same seat body 13 and the same body 21. Referring to Figure 3 , taking the example of setting two water inlets 23, the elevation view of the seat body 13 can be set as a circle, and the two water inlets 23 can be symmetrically arranged relative to the center of the seat body 13. Among them, the two water inlets 23 divide the inner side of the seat body 13 into multiple continuous edges 131, and each continuous edge 131 is arranged in an Archimedean spiral and has the same spiral direction. For example, Figure 3 the two water inlets 23 in Figure 3 divide the inner side of the seat body 13 into two continuous edges 131. The left continuous edge 131 is away from the center of the seat body 13 in the direction from bottom to top towards the upper water inlet 23, and the right continuous edge 131 is inFigure 3 From top to bottom, away from the center of the seat body 13 in the direction of approaching the lower water inlet 23, that is to say, the gaps L between the left continuous edge 131 and the right continuous edge 131 and the outer edge 22a of the blade 22 both increase along Figure 3 the clockwise direction of the middle seat body 13. Taking the blade rotating in the clockwise direction as an example, in the same continuous edge 131 of the seat body 13, the end close to the water inlet 23 is regarded as the downstream, and the end far from the water inlet 23 is regarded as the upstream. The blade 22 can drive the liquid to flow from the upstream of the continuous edge 131 to the downstream, and each continuous edge 131 corresponds to a water inlet 23 arranged at the downstream.

[0048] In the embodiment of the present invention, by providing a plurality of water inlets, the liquid in the water passing cavity can be respectively led out from the plurality of water inlets, which is beneficial to improving the efficiency of the water flow circulating in the barrel assembly. In some embodiments, as Figure 3 shown, a plurality of blades 22 are circumferentially and spaced apart, and the plurality of blades 22 are arranged radially. Each blade 22 is arc-shaped and the bending directions of each arc are the same. Among them, the radial arrangement means that one end of the blade is arranged at a position close to the axis of symmetry of the body, and the other end of the blade is arranged at a position close to the edge of the body, so that the blade extends substantially along the radial direction of the body. The blade can be set to be arc-shaped, and the blade bends in the same direction in the circumferential direction of the body. For example Figure 3 the blades in the shown embodiment all bend in the clockwise direction. In the embodiment of the present invention, the flow intensity of the liquid is related to the bending direction of the blade and the rotation direction of the blade.

[0049] In the embodiment of the present invention, by setting the blade to be arc-shaped, when the bending direction of the blade is consistent with the increasing direction of the radial distance, the blade rotates in the bending direction, which is beneficial to increasing the pressure of the liquid flow. In addition, setting the blade to be arc-shaped makes the tangential angle of the liquid in contact with the blade surface increase and the normal angle decrease when the liquid impacts the blade, which is beneficial to reducing the noise generated by the liquid impacting the blade and improving the comfort of using the laundry treatment device.

[0050] In some embodiments, as shown in combination with Figure 4 the seat body 13 includes a bottom wall 132, a side wall 133 and a protrusion 134. The bottom wall 132 extends vertically along the axis, that is to say, the direction of the largest dimension in the bottom wall 132 is perpendicular to the axis of the washing tub 1 ( Figure 1 the up and down direction shown). The bottom wall 132 is fixedly connected to the washing tub 1, and the bottom wall 132 and the washing tub 1 are relatively fixed both axially and circumferentially. However, the embodiment of the present invention does not limit the connection relationship between the bottom wall 132 and the washing tub 1. That is to say, the bottom wall 132 and the washing tub 1 can be detachably connected by means of a clamping structure, screws, etc., and the bottom wall 132 and the washing tub 1 can also be integrally formed by means of injection molding, etc.

[0051] The side wall 133 is arranged around the edge of the bottom wall 132. The side wall 133 and the bottom wall 132 form an open space, and the open space can form a water passage cavity. The direction of the opening faces away from the bottom of the barrel body. The extending direction of the side wall 133 is perpendicular to the extending direction of the bottom wall 132. The protruding part 134 protrudes radially inwards from the side wall 133 and extends circumferentially. Inward means the direction towards the center of the bottom wall 132. One end of the protruding part 134 is connected to the inner side of the side wall 133, and the other end of the protruding part 134 extends inwards. The edge of the protruding part 134 in the circumferential direction forms the water inlet 23. Among them, the edge part of the protruding part 134 adjacent to the blade 22 in the radial direction is arranged in an Archimedean spiral, that is, the continuous edge of the protruding part 134 is the Figure 3 continuous edge 131 in

[0052] In the embodiment of the present invention, by arranging an open space on the seat body, the blade can be arranged in the open space, the edge of the protruding part forms an Archimedean spiral, and the protruding part itself forms a water inlet, so that the liquid guided by the blade can directly flow to the water inlet along the contour line under the action of the protruding part, which is beneficial to improving the efficiency of liquid diversion.

[0053] In some embodiments, as shown in Figure 4 the protruding part 134 includes a first sub-protruding part 1341 and a second sub-protruding part 1342 that are stacked in the axial direction (the z direction shown in Figure 4 ). The first sub-protruding part 1341 is adjacent to the blade 22 in the radial direction (the direction in the xy plane shown in Figure 4 ). Among them, the radial edge of the first sub-protruding part 1341 is arranged in an Archimedean spiral. One end of the first sub-protruding part 1341 in the radial direction is connected to the side wall 133, and the other end of the first sub-protruding part 1341 in the radial direction is close to the edge of the blade. One surface of the first sub-protruding part 1341 close to the blade in the radial direction is set as the contour of an Archimedean spiral. Among them, the Archimedean spiral represents the change trend of the first sub-protruding part 1341 in the circumferential direction, and the size of the first sub-protruding part 1341 in the same axial direction can remain unchanged. In the case of multiple water inlets 23 being provided, the protruding part 134 has multiple first sub-protruding parts 1341 and second sub-protruding parts 1342. Taking Figure 4 as an example, there are two water inlets 23 on the seat body 13. The seat body 13 has two first sub-protruding parts 1341 in the circumferential direction and two second sub-protruding parts 1342 in the circumferential direction. Each first sub-protruding part 1341 is arranged in an Archimedean spiral.

[0054] The first sub-protruding part 1341 is in the axial direction (the Figure 4In the z - direction shown, it has opposite sides, one side close to the bottom wall 132 and the other side away from the bottom wall 132. The second sub - protruding part 1342 is farther from the bottom wall 132 than the first sub - protruding part 1341. Among them, the first sub - protruding part 1341 protrudes at least partially radially inwards relative to the second sub - protruding part 1342. That is to say, the radial extension dimension M1 of the first sub - protruding part 1341 is greater than the radial extension dimension M2 of the second sub - protruding part 1342, so that the second sub - protruding part 1342 and the first sub - protruding part 1341 form a stepped structure axially, and a stepped surface 1343 can be formed between the inner side wall of the second sub - protruding part 1342 and the top wall of the first sub - protruding part 1341. Combining Figure 5 As shown, during the cooperation process of the wave disk 2 and the seat body 13, the edge of the main body 21 can abut against the stepped surface 1343, so that a water - passing cavity 112 can be formed between the main body 21 and the seat body 13.

[0055] In the embodiment of the present invention, by setting the protruding part as the first sub - protruding part and the second sub - protruding part, the stepped surface formed by the second sub - protruding part and the first sub - protruding part can be adapted to the edge of the main body. The first sub - protruding part can independently form the structure of an Archimedean spiral. The structure of the first sub - protruding part is not restricted by the second sub - protruding part, which is convenient for processing and is beneficial to improving the efficiency of water diversion.

[0056] In some embodiments, combining Figure 4 and Figure 5 As shown, the second sub - protruding part 1342 is adjacent to the main body 21 of the wave disk 2 in the radial direction ( Figure 4 the plane formed by xy shown), and the radial edge of the second sub - protruding part 1342 is circularly arranged. That is to say, the main body 21 of the wave disk 2 is circularly arranged in the radial direction, so the radial edge of the second sub - protruding part 1342 is also circularly arranged, making the edge of the main body 21 more conformable to the inner surface contour of the second sub - protruding part 1342, which is beneficial to reducing the possibility of liquid flowing between the main body 21 and the second sub - protruding part 1342.

[0057] As Figure 2 shown, the embodiment of the present invention also provides a laundry treatment device. The laundry treatment device is provided with a water - guiding device 3. The water - guiding device is arranged in the cavity 11. A part of the water - guiding device 3 can be arranged in the washing cavity 111, and another part can be arranged in the water - passing cavity 112; or, the water - guiding device 3 is completely arranged in the washing cavity 111, as long as one end ( Figure 2 the lower end shown) of the water - guiding device 3 is communicated with the water inlet 23. It should be noted that "communicated" means that one end of the water - guiding device 3 is close to the water inlet 23 or one end of the water - guiding device 3 is directly connected to the main body 21 or the washing tub 1, and the water inlet 23 is used as one end of the water - guiding device 3. The water - guiding device 3 is provided with a water - guiding channel 32 for guiding water from the water inlet 23 to the washing cavity 111. The water - guiding channel 32 is along the axial direction (Figure 2 extends in the vertical direction as shown. In the embodiment of the present invention, by providing the diversion channel 32, the liquid in the water passing cavity 112 can enter the diversion channel 32 from the water inlet 23, and then flow back to the washing cavity 111 from the diversion channel 32. The liquid in the washing cavity 111 can also flow to the water passing cavity 112 through the water passing holes 211, so that the liquid circulates between the washing cavity 111 - the water passing cavity 112 - the diversion channel 32, improving the flow efficiency of the liquid in the washing cavity 111.

[0058] Through the above setting of the barrel assembly, when the wave plate rotates in a certain direction (for example Figure 3 during the forward rotation as shown), the water pressure entering the diversion channel 32 can be relatively large. If the part of the diversion channel 32 where the water flow enters during the forward rotation of the wave plate is set as the waterfall channel, the water flow intensity of the waterfall channel is relatively large, which can improve the washing quality of the clothes.

[0059] In some embodiments, as Figure 5 shown, the partition 34 is at least partially arranged in the diversion channel 32, and the partition 34 can be fixedly connected to the waterfall plate 31 to divide the diversion channel 32 into a first channel 321 and a second channel 322 that both extend axially; for example, when the diversion channel 32 is formed outside the waterfall plate 31 (away from the axis of symmetry of the washing barrel), the partition 34 is also correspondingly arranged outside the waterfall plate 31; there are various ways to fixedly connect the partition 34 to the waterfall plate 31, which can be a detachable connection or an integrally formed permanent connection, etc. Among them, there can be multiple partitions 34, for example, multiple axially extending strip-shaped plates are arranged at intervals to divide the diversion channel 32 into the first channel 321 and the second channel 322. The first channel 321 and the second channel 322 are divided functionally. For example, they are divided into a waterfall function and a filtering function. The first channel 321 can represent the waterfall flow channel, and the water flow sprays out to the washing cavity through the outlet of this flow channel. The second channel 322 can represent the filtering flow channel, and the water flow flows to the filter through the outlet of this flow channel and then flows back to the washing cavity. The first channel 321 and the second channel 322 corresponding to each diversion channel can each be a channel, both extending axially along the washing barrel. When multiple water inlets 23 are provided, the corresponding water guiding devices are also provided in multiple numbers. Each water inlet corresponds to a diversion channel 32, and the water inlets and the diversion channels are in the same position in the circumferential direction of the washing barrel, and can both be evenly distributed in the circumferential direction.

[0060] In some embodiments, in combination with Figure 5 and Figure 6 shown, the water guiding device 3 includes a waterfall plate 31, a filter 33 and a partition 34. As Figure 5As shown, the waterfall plate 31 has a diversion channel 32 inside. The waterfall plate 31 itself can serve as one or more sides adjacent to the diversion channel 32. However, at least one side of the diversion channel 32 is not enclosed by the waterfall plate 31, thus forming an opening. At least a part of the opening of the diversion channel 32 can be enclosed by other components of the waterfall plate 31. This component can be part of the water guiding device 3 or not part of the water guiding device 3. For example, the waterfall plate 31 can be fixed on the inner wall surface of the barrel and make the inner wall surface of the barrel adjacent to the diversion channel 32, that is, at least part of the opening of the diversion channel is enclosed by the barrel. It should be noted that the diversion channel 32 is a space that can accommodate water flow. The diversion channel 32 can communicate with the washing cavity and the water passing cavity. Water flow enters the diversion channel 32 from the water passing cavity and then enters the washing cavity from the diversion channel 32. That is to say, one end of the diversion channel 32 is connected to the water inlet 23. Among them, the water inlet 23 can be an opening formed by the end face where the base 13 is flush with the main body 21. One end of the waterfall plate 31 can extend into the water passing cavity 112 through the water inlet 23. One end of the waterfall plate 31 ( Figure 5 the lower end shown) can also be flush with the water inlet 23, so that the liquid in the water passing cavity 112 can enter the diversion channel 32 from the water inlet 23.

[0061] As Figure 5 shown, the waterfall plate 31 also has a water outlet 35 that communicates with the diversion channel 32 and is spaced from the water inlet 23. The water outlet 35 is used to drain the water in the diversion channel 32 into the washing cavity. The water outlet 35 can be located above the water inlet 23. Under the rotation of the wave disk 2, water flow can enter the diversion channel 32 from the lower water inlet 23 and be discharged into the washing cavity from the upper water outlet 35, thus forming an upward water flow in the diversion channel 32. And when the water flow discharges from the water outlet 35 out of the diversion channel 32, due to the height difference between the water outlet 35 and the water inlet 23, a waterfall-like spraying effect can be formed to wash the clothes in the washing cavity and improve the cleaning effect.

[0062] In some embodiments, such as Figure 5As shown in the figure, the waterfall plate 31 is provided with a water outlet 35 communicating with the first channel 321, and the second channel 322 is separated from the water outlet 35. Among them, the first channel 321 communicates with the water inlet 23 and the water outlet 35; that is, when the water flow enters the diversion channel 32 through the water inlet 23, one flow mode is to enter the first channel 321, and then be discharged through the water outlet 35 to form a jet of water and return to the washing cavity. The second channel 322 communicates with the water inlet 23 and is separated from the water outlet 35; that is, when the water flow enters the diversion channel 32 through the water inlet 23, another flow mode is to enter the second channel 322, and the second channel 322 is not communicated with the water outlet 35, so that the water flow entering the second channel 322 will not be discharged through the water outlet 35, but is discharged into the filter 33 communicated with the second channel 322, and after being filtered by the filter 33, it flows back to the washing cavity again.

[0063] As Figure 6 shown, the filter 33 is arranged on the side of the waterfall plate 31 opposite to the diversion channel 32. For example, if the diversion channel 32 is arranged on the outer side of the waterfall plate 31 (the side far from the axis of symmetry of the washing tub), then the filter 33 is opposite to the diversion channel 32 and is arranged on the inner side of the waterfall plate 31 (the side close to the axis of symmetry of the washing tub). The filter 33 is used to filter debris such as lint in the water flow. The filter can be fixed relative to the waterfall plate 31 and communicated with the second channel 322, so that the water flow passing through the second channel 322 can flow into the washing cavity after passing through the filter 33, and then the water flow in the washing cavity flows into the water passing cavity through the water passing holes, and the water flow in the water passing cavity enters the second channel 322 again through the water inlet 23 to form a water flow filtration cycle. In addition, a protection member with an opening gap can be arranged on the side of the filter 33 far from the waterfall plate 31, so that the water flow discharged from the filter 33 can be discharged through the gap on the protection member, so that the clothes do not directly contact the filter 33 and affect the fixing stability of the filter 33.

[0064] The water guiding device provided by the embodiment of the present invention divides the cavity formed by the waterfall plate into a first channel and a second channel by arranging a partition on the waterfall plate. Both the first channel and the second channel communicate with the water inlet but are separated to respectively realize the waterfall cycle of the water flow in the washing tub and the water flow filtration, so that the water guiding device can integrate the functions of waterfall and filtration, and there is no need to separately arrange a plurality of waterfall plates and filters in the washing tub.

[0065] The wave plate 2 in the embodiment of the present invention can rotate forward and reverse around the axis, and the first channel 321 and the second channel 322 take turns to intake water. The principles of the first channel 321 and the second channel 322 taking turns to intake water are described below:

[0066] As Figure 3As shown, during the clockwise rotation of the blade 22 (which can be understood as the forward rotation of the wave disk), the water flow in the water passage chamber rotates clockwise in the gap driven by the blade 22. The water flow rotates clockwise, and thus first reaches the first inlet 231 of the water inlet 23, enters the first channel communicating with the first inlet 231, and forms a waterfall water flow back into the washing chamber. Since the gap increases near the first inlet 231, there is a relatively large water pressure at the first inlet 231; and the bending direction of the blade 22 is also clockwise, which can drive a large amount of water flow to reach the first inlet 231; therefore, it can provide a relatively large water pressure for the water flow ejected by the waterfall plate, which is beneficial to improving the quality of waterfall cleaning. Correspondingly, during the clockwise rotation of the blade 22, the water flow entering the second inlet 232 is relatively small and can be ignored, that is, the clockwise rotation of the blade 22 mainly realizes the waterfall cycle of the water flow.

[0067] As Figure 3 shown, during the counterclockwise rotation of the blade 22 (which can be understood as the reverse rotation of the wave disk), the water flow in the water passage chamber rotates counterclockwise in the gap driven by the blade 22. The water flow rotates counterclockwise, and thus first reaches the second inlet 232 of the water inlet 23, enters the second channel communicating with the second inlet 232, and forms a filtered water flow back into the washing chamber. Since the gap becomes smaller during the process of approaching the second inlet 232, there is a relatively small water pressure at the second inlet 232; and the bending direction of the blade 22 is clockwise, which is opposite to the rotation direction of the water flow, and the amount of water reaching the second inlet 232 is relatively small; therefore, the water pressure of the water flow entering the second channel and then flowing back into the washing chamber through the filter is relatively small, but as long as the water can flow into the second inlet, the filtration cycle can be realized and the filtration function of the water flow can be completed. Correspondingly, during the counterclockwise rotation of the blade 22, the water flow entering the first inlet 231 is relatively small and can be ignored, that is, the counterclockwise rotation of the blade 22 mainly realizes the filtration cycle of the water flow.

[0068] In the embodiment of the present invention, by connecting the water inlet to the channels with the waterfall and filtration functions in the water guiding device, it is possible to make the two channels in the diversion channel alternately intake water from the water inlet during the rotation of the wave disk in different directions, alternately realizing the functions of waterfall and filtration of the water flow. And during the waterfall process of the water flow, a relatively large water intake pressure can be provided through the gap between the wave disk and the washing tub, so as to provide a relatively large waterfall pressure and improve the cleaning quality.

[0069] In some embodiments, in combination with Figure 3 and Figure 5As shown, the partition plate 34 extends into the water inlet 23. The partition plate 34 divides the water inlet 23 into a first inlet 231 and a second inlet 232 that are arranged side by side in the circumferential direction. It should be noted that the circumferential direction refers to the direction around the edge of the bottom wall 132. The arrangement direction of the first inlet 231 and the second inlet 232 is not the radial direction or other directions but the circumferential direction. Because during the rotation of the blade 22, the blade 22 drives the water flow to move in the circumferential direction. By arranging the first inlet 231 and the second inlet 232 in the circumferential direction, when the blade rotates in different circumferential directions, the order in which the water flow reaches the first inlet 231 and the second inlet 232 of the same water inlet 23 is opposite. Thus, it is possible to set different rotation directions of the blade to match different diversion channels for water inlet, realizing different water guiding functions corresponding to different rotation directions, and thus realizing the alternation of the spraying function and the filtering function.

[0070] The extension described in the embodiment of the present invention refers to the forming direction of the partition plate 34. However, there may be no direct connection relationship between the partition plate 34 in the diversion channel 32 and the partition plate 34 in the water inlet 23. That is to say, the partition plate 34 in the diversion channel 32 can be connected to the spraying plate 31, and the partition plate 34 in the water inlet 23 can be connected to the bottom wall of the barrel body or the seat body 13. Of course, in some embodiments, the partition plate in the diversion channel can also be directly connected to the partition plate in the water inlet. As Figure 3 shown, the first inlet 231 is communicated with the first channel 321 ( Figure 5 shown). The second inlet 232 is communicated with the second channel 322 ( Figure 5 shown). When there are multiple water inlets 23 provided in the seat body 13, the arrangement order of the first inlet 231 and the second inlet 232 in each water inlet 23 is the same. For example, Figure 3 in the upper water inlet 23, the first inlet 231 and the second inlet 232 are arranged in the clockwise direction, Figure 3 and in the lower water inlet 23, the first inlet 231 and the second inlet 232 are also arranged in the clockwise direction. When the blade 22 rotates clockwise, the liquid after being pressurized by the Archimedes spiral will first reach the first inlet 231. Under the blocking action of the partition plate 34, most of the liquid enters the first inlet 231. When the blade 22 rotates counterclockwise, the liquid stirred by the blade 22 will first reach the second inlet 232, and most of the liquid flows into the second inlet 232.

[0071] In the embodiments of the present invention, a partition plate separates the first inlet and the second inlet. When the blades rotate forward and backward, the water flow first reaches the opening near the end of the Archimedes spiral, enabling the blades rotating in different directions to drive the water flow towards different openings. When rotating clockwise, it is beneficial to utilize the Archimedes spiral to increase the water pressure entering the first channel, thereby improving the spraying effect of the spraying plate. When rotating in the reverse direction, it is also possible to achieve the liquid entering the second channel to complete the filtering function, realizing the alternating cycle of the spraying and filtering functions of the laundry treatment device.

[0072] In some embodiments, as Figure 6 shown, the water guiding device 3 further includes a water return plate 36, and the water return plate 36 is fixed on the side of the spraying plate 31 adjacent to the diversion channel 32. The water return plate 36 can be arranged adjacent to the spraying plate 31 to form the diversion channel 32 to fix the entire water guiding device 3. The water return plate 36 is provided with a third channel 37, and the third channel 37 is separated from both the first channel 321 and the second channel 322. The water return plate 36 can surround to form the third channel 37, or can be fixed to the barrel body to jointly form the third channel 37.. The third channel 37 is arranged at intervals with the first channel 321 and the second channel 322 so that the water flow will not be discharged from the third channel 37 during the laundry washing process. The third channel 37 can also be closed in the laundry washing state until it is opened in the state of needing to drain water, so that the water flow will not enter the third channel 37 during the laundry washing state.

[0073] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
