[0030] The present invention provides a barrel assembly, which can be applied to clothes processing devices such as washing machines, washer-dryers, etc. It should be noted that the application scenario type of the present invention does not limit the barrel assembly of the present invention.

[0031] The following describes the washing working principle by taking the barrel assembly used in a washing machine as an example. In the washing state, the clothes are placed in the barrel assembly, and the driving device drives the impeller disposed in the barrel assembly to rotate relative to the barrel assembly, thereby driving the clothes and the liquid in the barrel assembly to fluctuate, so that the clothes rotate and tumble with the liquid, and the flowing liquid impacts the clothes, thereby removing the dirt on the clothes. The liquid in the embodiments of the present invention includes but is not limited to pure water, tap water, a mixed liquid with a detergent, and a liquid that may contain impurities such as lint.

[0032] like Figure 1As shown, an embodiment of the present invention provides a barrel body assembly, which includes an outer barrel 1, an inner barrel 2 and a pulsator 3. The outer barrel 1 is provided with a drainage hole, which can be provided on the bottom wall of the outer barrel 1 and located at the outer peripheral edge of the bottom wall of the outer barrel 1, so as to penetrate the inner and outer sides of the outer barrel 1 and discharge the liquid in the outer barrel 1 to the outside. The inner barrel 2 is rotatably arranged in the outer barrel 1, and a first cavity 11 is provided between the inner barrel 2 and the outer barrel 1. It should be noted that the inner barrel 2 and the outer barrel 1 can be relatively stationary and not rotated in the washing state, and the inner barrel 2 rotates relative to the outer barrel 1 in the dehydration state. The first cavity 11 can be formed between the outer circumferential surface of the inner barrel 2 and the inner circumferential surface of the outer barrel 1 and between the outer bottom surface of the inner barrel 2 and the inner bottom surface of the outer barrel 1. The first cavity 11 is connected to the drainage hole, and the inner barrel 2 has a first direction ( Figure 1 The inner barrel 2 is provided with a filter hole 22, which connects the second cavity 21 inside the inner barrel 2 with the first cavity 11.

[0033] like Figure 1 As shown, the inner tub 2 includes a side wall 23 and a bottom wall 24. The side wall 23 is arranged around the circumference of the bottom wall 24, that is, the side wall 23 is arranged around the edge of the bottom wall 24.

[0034] like Figure 1 As shown, the side wall 23 is along the first direction ( Figure 1 The first direction is not limited to the direction of a certain straight line, but can be the direction of a group of parallel lines. For example, the first direction is the up-down direction and is not limited to the direction of a certain straight line extending up and down; for example, the first direction can be the axial direction of the inner barrel 2. The side wall 23 is provided with a plurality of first water holes 231. It should be noted that the first water holes 231 are used for the passage of liquids such as water flow, while blocking or reducing the probability of the passage of debris such as wire scraps. Correspondingly, the diameter of the first water holes 231 can be set to be smaller. In some embodiments, the first water holes 231 can be arranged on the side wall 23 at a set interval. For example, the first water holes 231 form a row around the circumference of the inner barrel 2 and form a column along the axial direction of the inner barrel. The first water holes 231 connect the first cavity 11 and the second cavity 21 and are used to guide the liquid between the first cavity 11 and the second cavity 21.

[0035] In the embodiment of the present invention, the impeller 3 is arranged at the bottom of the second cavity 21. The impeller 3 may be arranged next to the bottom wall 24, or may be arranged at a distance from the bottom wall 24. The embodiment of the present invention does not limit the specific positional relationship between the impeller 3 and the bottom wall 24, as long as the distance from the impeller 3 to the bottom is within the preset area. The specific preset area can be set according to actual needs. The impeller 3 is rotatably connected to the inner barrel 2. During the washing process, the impeller 3 can rotate to drive the washing and liquid in the second cavity 21 to rotate, thereby achieving the washing effect. The impeller 3 can also guide the liquid in the second cavity 21 to the filter hole 22, so that the liquid in the second cavity 21 flows from the filter hole 22 to the first cavity 11, and the liquid in the first cavity 11 flows to the first water hole 231 through the resistance of the outer barrel 1, and returns to the second cavity 21 from the first water hole 231.

[0036] like Figure 1 As shown, the length extension direction of the bottom wall 24 can be regarded as perpendicular to the first direction. In the case where the bottom wall is a regular structure, the extension direction of the bottom wall is the length direction of the bottom wall; in the case where the bottom wall is an irregular structure, the extension direction of the bottom wall is the maximum extension direction of the outer contour of the bottom wall. For example, the length of the bottom wall in the first direction is the largest, so the first direction can be regarded as the extension direction of the bottom wall. The bottom wall 24 is connected to one end of the side wall 23 in the first direction ( Figure 1 The lower end of the z direction). The bottom wall 24 can be approximately regarded as a flat plate, and the surface of the bottom wall 24 adjacent to the second cavity 21 can be perpendicular to the first direction; of course, the bottom wall 24 can also be an arc panel, and the tangent of the surface of the bottom wall 24 adjacent to the second cavity 21 can be perpendicular to the first direction. The bottom wall 24 can be located below the impeller in normal use. Among them, except for the filter hole 22, there are no other through holes on the bottom wall 24 that can be used to conduct water flow. That is, in the area of ​​the bottom wall 24 facing the rib 4, the bottom wall 24 is not provided with a water hole. The advantage of this design is that when the liquid in the second cavity 21 enters the first cavity 11 through the filter hole 22, the liquid will not enter the first cavity 11 from the bottom of the inner barrel 2, thereby increasing the liquid flow from the side wall 23 of the inner barrel 2 to the second cavity 21, and improving the filtration efficiency of the side wall 23 of the inner barrel 2.

[0037] The area where the bottom wall 24 faces the ribs 4 is the area where the bottom wall 24 overlaps with the ribs 4 in the direction perpendicular to the extension direction of the bottom wall. Of course, a hole for penetrating the driving device can be provided on the bottom wall 24, so that the driving device can penetrate into the second cavity 21 to drive the pulsator 3 to rotate. When the driving device is penetrated in the second cavity 21, the driving device can close the bottom of the second cavity 21. The other end of the second cavity 21 relatively far from the bottom wall 24 is an open structure, and one end of the open structure can be used to take and put the washing. Among them, the extension direction of the bottom wall 24 and the extension direction of the side wall 23 can be set at a set angle. In some embodiments, the extension direction of the bottom wall 24 and the extension direction of the side wall 23 can be basically perpendicular. Basically perpendicular includes the situation that the angle between the extension direction of the bottom wall 24 and the extension direction of the side wall 23 is not strictly 90 degrees. It can be considered that the angle between the two directions is greater than 80 degrees, which is basically perpendicular, so that the situation of processing and installation errors can be covered.

[0038] like Figure 1 As shown, the connection between the side wall 23 and the bottom wall 24 is provided with a filter hole 22, and the connection between the side wall 23 and the bottom wall 24 represents the area where the ends of the side wall 23 and the bottom wall 24 in the extension direction intersect, that is, the connection not only includes the boundary position where the ends of the side wall 23 and the bottom wall 24 in the extension direction intersect, but also includes the area where the distance from the boundary position is less than or equal to a set value, and the set value can be half of the maximum size of the side wall 23 in the first direction. In other words, the filter hole 22 is provided on both the side wall 23 and the bottom wall 24. The filter hole 22 connects the first cavity 11 and the second cavity 21 to guide the liquid in the second cavity 21 to the first cavity 11 between the inner barrel 2 and the outer barrel 1.

[0039] The cross-sectional area of ​​the filter hole 22 in the embodiment of the present invention is larger than the cross-sectional area of ​​the first water hole 231. Figure 2-4 As shown, the filter hole 22 includes a first through hole 221 opened on the side wall 23 and a second through hole 222 opened on the bottom wall 24. The first through hole 221 is connected to the second through hole 222. The cross section cdef of the first through hole 221 and the cross section abef of the second through hole 222 are used as two side surfaces of the triangular prism. The other side surface of the triangular prism can be regarded as the cross section abcd of the filter hole 22. Then, the cross-sectional area of ​​the filter hole 22 is the cross-sectional area of ​​the other side surface abcd of the triangular prism. Figure 1In the case where the first water through hole 231 is a regular columnar hole, the cross-sectional size of the first water through hole 231 in the direction from the inner surface of the side wall 23 to the outer surface of the side wall 23 is the same, and the cross-sectional area of ​​the first water through hole 231 can be the cross-sectional area at any position in the direction from the inner surface of the side wall 23 to the outer surface of the side wall 23; in the case where the first water through hole 231 is an irregular hole, the cross-sectional area of ​​the first water through hole 231 in the direction from the inner surface of the side wall 23 to the outer surface of the side wall 23 can be inconsistent, and the cross-sectional area of ​​the filter hole 22 can be larger than the cross-sectional area of ​​the first water through hole 231 on the outer surface of the side wall 23. In the embodiment of the present invention, the cross-sectional area of ​​the filter hole 22 is set to be larger than the cross-sectional area of ​​the first water hole 231. It can be understood that the cross-sectional area of ​​the first water hole 231 is smaller than the cross-sectional area of ​​the filter hole. Then, the wire scraps in the second cavity 21 can flow from the filter hole 22 to the first cavity 11 along with the liquid, but it is difficult for the wire scraps to flow from the first cavity 11 through the first water hole 231 to the second cavity 21 along with the liquid. That is, the risk of the wire scraps in the first cavity 11 passing through the first water hole 231 is reduced, thereby improving the filtering performance of the barrel assembly.

[0040] The filtering process of the filtering hole 22 is explained below:

[0041] like Figure 1 As shown, when the barrel assembly is in a washing state, laundry is put into the second cavity 21 from the open end of the second cavity 21, and the impeller rotates relative to the inner barrel, thereby driving the movement of the laundry and liquid in the second cavity 21, and impact and friction are generated between the laundry and the liquid to simulate the rubbing of the laundry; during the flow of liquid, the rotation of the impeller drives the flow of liquid at the bottom of the second cavity, thereby driving the liquid in the second cavity 21 to flow from the filter hole 22 at the connection between the side wall 23 and the bottom wall 24 to the first cavity 11, and in this process, the lint flows into the first cavity 11 together with the liquid; a large negative pressure is generated in the second cavity 21 due to the reduction of liquid, which promotes the first cavity 11 The liquid in the second cavity 21 flows from the first water hole 231 of the side wall 23 to the second cavity 21 to replenish the reduced liquid in the second cavity 21, thereby realizing water circulation in the entire barrel body assembly. In this process, since the cross-sectional area of ​​the first water hole 231 is smaller than the cross-sectional area of ​​the filter hole 22, it is more difficult for the wire scraps that enter the second cavity 21 through the filter hole 22 to enter the second cavity 21 from the first water hole 231. As a result, in the process of the liquid in the second cavity 21 flowing into the first cavity 11, a large amount of wire scraps are retained in the first cavity 11; when the barrel body assembly is in a dehydrated state, the wire scraps in the first cavity 11 will be automatically discharged from the drainage hole of the outer barrel 1 to the outside of the barrel body assembly along with the liquid.

[0042] In the embodiment of the present invention, the filter hole is arranged at the connection between the side wall and the bottom wall, and the rotation of the impeller drives the liquid to enter the first cavity from the filter hole. Under the combined action of the driving force of the impeller and the resistance of the bottom of the outer barrel, the liquid entering the first cavity is directly guided to the upper part of the first cavity, thereby reducing the risk of liquid flowing back from the filter hole to the second cavity, thereby eliminating the need to set an extra one-way valve at the filter hole, simplifying the structure of the filter hole, and reducing the difficulty and cost of manufacturing the barrel body assembly. Compared with the method of setting an opening only at one place on the side wall or the bottom wall, the filter hole arranged at the connection between the side wall and the bottom wall can increase the cross-sectional area of ​​the filter hole while meeting the strength of the inner barrel, thereby improving the efficiency of the filter hole diversion, and further improving the filtration efficiency of the barrel body assembly.

[0043] Moreover, in the embodiment of the present invention, in the non-dehydration state, the liquid in the second cavity enters the first cavity through the filter hole driven by the impeller, and the liquid in the first cavity flows into the second cavity through the first water hole, thereby circulating the fluid in the barrel assembly. It can be seen that the flow trajectory of this circulating flow is basically fixed, and follows the flow trajectory of the second cavity-filter hole-first cavity-first water hole-second cavity. This basically fixed flow trajectory helps the water flow to be guided into the second cavity through the first water hole and impact the clothes in the second cavity, thereby enhancing the washing effect.

[0044] In some embodiments, Figure 1 As shown, the side wall 23 includes a first side wall 232 and a second side wall 233. The first side wall 232 and the second side wall 233 are detachably connected, wherein the first side wall 232 and the second side wall 233 can be fixedly connected by a connecting piece, and a clamping structure can be provided on the first side wall 232 and the second side wall 233 to realize a detachable connection. The embodiment of the present invention does not limit the specific connection form between the first side wall 232 and the second side wall 233, and the position where the first side wall 232 and the second side wall 233 are connected does not need to conduct liquid. Among them, the first side wall 232 and the second side wall 233 are both along the first direction ( Figure 1The first side wall 232 extends in the z direction as shown, and the first side wall 232 can be smoothly connected to the second side wall 233, that is, there is no sudden curvature value at the position where the first side wall 232 and the second side wall 233 are connected. One end of the second side wall 233 is connected to the bottom wall 24, and the other end of the second side wall 233 is connected to the first side wall 232. The first water hole 231 runs through the inner and outer sides of the first side wall 232, and the filter hole 22 is arranged at the connection between the second side wall 233 and the bottom wall 24. In some embodiments, the length of the second side wall 233 in the first direction is less than 0.3 times the length of the first side wall 232 in the first direction. Setting the second side wall 233 within a certain size range can reduce the risk of the liquid guided out from the filter hole 22 flowing back to the second cavity 21, and increase the flow rate of the liquid in the first cavity 11 from the first water hole 231 to the second cavity 21.

[0045] In some embodiments, Figure 2 As shown, the extension direction of the side wall 23 is perpendicular to the extension direction of the bottom wall 24. For example, when the side wall 23 extends along the first direction, the extension direction of the bottom wall 24 is perpendicular to the first direction. The extension direction of the bottom wall 24 may be the direction of the maximum dimension of the outer contour of the bottom wall 24. In the embodiment of the present invention, by making the extension direction of the side wall 23 perpendicular to the extension direction of the bottom wall 24, the cross section of the first through hole 221 on the side wall 23 and the cross section of the second through hole 222 on the bottom wall 24 are perpendicular to each other, thereby increasing the cross-sectional area of ​​the filter hole 22 and increasing the structural strength of the inner barrel 2.

[0046] In some embodiments, in combination Figure 2-4 As shown, the cross section of the filter hole 22 is a rectangle, wherein the cross section cdef of the first through hole 221 on the second side wall 233 can be a rectangle or a square; the cross section abef of the second through hole 222 on the bottom wall 24 can be a rectangle or a square, and the cross section cdef of the first through hole 221 and the cross section abef of the second through hole 222 are used as two sides of the triangular prism, and the other side abcd of the triangular prism can be regarded as the cross section of the filter hole 22, then, the cross section abcd of the filter hole 22 corresponds to a rectangle or a square. In the embodiment of the present invention, by setting the cross section abcd of the filter hole 22 in a rectangle, the conduction of the filter hole 22 is improved on the basis of satisfying the structural strength of the inner barrel 2, thereby improving the filtering efficiency of the barrel assembly.

[0047] In some embodiments, Figure 4 As shown, the first through hole 221 is in a direction perpendicular to the first direction ( Figure 3 The cross-sectional area in the x direction is 0~6400mm 2, that is, the cross-sectional area of ​​the cross section cdef. Wherein, when the first through hole 221 is set as a rectangular structure, the cross section of the first through hole 221 in the direction perpendicular to the first direction can be regarded as the first rectangle cdef, the length of the two sides parallel to the first direction in the first rectangle cdef can be less than 80mm, and the length of the two sides perpendicular to the first direction in the first rectangle cdef can be less than 80mm. The cross-sectional area of ​​the second through hole 222 in the first direction is 0 to 4000mm 2 . Among them, when the second through hole 222 is set to a rectangular structure, the cross-section of the second through hole 222 in the first direction can be regarded as a second rectangle abef, and the length of the side in the second rectangle abef can be less than 80mm or less than 50mm. In the embodiment of the present invention, the cross-sectional area of ​​the first through hole 221 and the second through hole 222 is set within a certain range, which is beneficial to improve the reliability of the structure of the inner barrel 2 and allows the lint and other debris in the second cavity 21 to flow into the first cavity 11; on the other hand, it can reduce the risk of foreign objects such as coins and buttons remaining in clothes falling into the filter hole 22 and entering the first cavity 11 due to the large cross-sectional area of ​​the filter hole 22.

[0048] In some embodiments, Figure 3 As shown, a plurality of filter holes 22 are provided, and the plurality of filter holes 22 are arranged at intervals along the circumference of the inner barrel. The number of filter holes 22 in some embodiments can be set to 1-12. Among them, the filter holes 22 are arranged at intervals along the circumference of the connection between the second side wall 233 and the bottom wall 24. In the embodiment of the present invention, the number of filter holes 22 can be increased, thereby increasing the liquid flow rate that can be diverted from the second cavity 21 to the first cavity 11 per unit time, thereby improving the filtering efficiency of the barrel assembly.

[0049] In some embodiments, in combination Figure 2-4 , the ratio of the cross-sectional area of ​​the plurality of filter holes 22 to the outer surface area of ​​the bottom wall 24 is 0.35-0.5. The cross-sectional area of ​​the filter hole 22 can refer to the explanation in the above-mentioned embodiment. The cross-sectional area of ​​the first through hole 221 and the cross-sectional area of ​​the second through hole 222 are taken as two sides of the triangular prism, and the other side of the triangular prism can be regarded as the cross-sectional area of ​​the filter hole 22. Then, the cross-sectional area of ​​the filter hole 22 is the cross-sectional area of ​​the other side of the triangular prism. The outer surface area of ​​the bottom wall 24 represents the surface area of ​​the bottom wall 24 close to the first cavity 11. The sum of the cross-sectional areas of the plurality of filter holes 22 can represent the liquid flow that can be conducted by the barrel assembly per unit time. The ratio of the sum of the cross-sectional areas of the plurality of filter holes 22 to the outer surface area of ​​the bottom wall 24 represents the degree of opening of the filter hole 22. Setting the ratio of the sum of the cross-sectional areas of the plurality of filter holes 22 to the outer surface area of ​​the bottom wall 24 within a certain range can not only meet the requirement that the inner barrel 2 has a strong flow-conducting efficiency, but also reduce the risk of fatigue failure caused by insufficient strength of the bottom of the inner barrel 2.

[0050] In some embodiments, Figure 5 As shown, the first water hole 231 is formed from the inner side of the inner tub 2 ( Figure 5 The left side shown) to the outside of the inner barrel 2 ( Figure 5 In other words, the aperture of the first water hole 231 decreases gradually from left to right, and the gradual shrinkage also means that the aperture change of the first water hole 231 can be a relatively gentle change without a sudden change in size. In the case where the cross-section of the first water hole 231 is circular, the cross-section of the first water hole 231 can be regarded as a cone that gradually shrinks from left to right. By setting the cross-sectional area of ​​the first water hole 231 close to the first cavity 11 to be smaller than the cross-sectional area close to the second cavity 21, it is not easy for debris such as wire scraps contained in the first cavity 11 to enter the second cavity 21 from the first water hole 231, thereby improving the filtering effect of the barrel assembly.

[0051] In some embodiments, Figure 5 As shown, the first water hole 231 is located on the side of the side wall 23 close to the first cavity 11 ( Figure 5 The cross-sectional diameter of the first water hole 231 (shown on the right side) is less than 5 mm. The diameter range of the first water hole 231 close to the first cavity 11 can not only conduct the liquid between the first cavity 11 and the second cavity 21, but also block the larger debris such as wire scraps between them in the first cavity 11. In the case where the cross-section of the first water hole 231 is a regular circle, the cross-sectional diameter of the first water hole 231 represents the diameter of the circle; in the case where the cross-section of the first water hole 231 is an irregular shape, the cross-sectional diameter of the first water hole 231 represents the length in the direction of the maximum dimension of the cross-sectional profile.

[0052] In some embodiments, Figure 1 As shown, the impeller 3 divides the second cavity 21 into a first sub-cavity 211 and a second sub-cavity 212, that is, the first sub-cavity 211 and the second sub-cavity 212 are separated from each other by the impeller 3, and a second water hole 31 is provided on the impeller 3 to connect the first sub-cavity 211 and the second sub-cavity 212, and the first sub-cavity 211 and the second sub-cavity 212 flow through the second water hole 31. The first sub-cavity 211 is close to the open side of the inner barrel 2 ( Figure 1 The second sub-cavity 212 is close to the bottom wall 24 ( Figure 1 In the embodiment of the present invention, the second cavity 21 is divided into a first sub-cavity 211 and a second sub-cavity 212, so that the liquid in the first sub-cavity 211 can only enter the second sub-cavity 212 through the second water hole 31, thereby filtering out a portion of debris with a larger diameter, such as coins, buttons, etc., and reducing the risk of debris with a large diameter entering the first cavity 11, thereby improving the stability of the operation of the clothing treatment device.

[0053] In some embodiments, Figure 1 As shown, the side of the impeller 3 adjacent to the second sub-cavity 212 ( Figure 1 A rib 4 is provided on the lower side (in the z direction as shown in the figure), and a plurality of ribs 4 can be provided, and the plurality of ribs 4 are arranged at intervals around the circumference of the impeller 3, and the ribs 4 themselves extend along the radial direction of the impeller 3. In the washing state, the driving device 5 drives the impeller 3 to rotate relative to the inner tub 2, and the ribs 4 rotate around the central axis with the impeller 3. The rotating impeller 3 can drive the water in the second sub-cavity 212 to fluctuate, and the water pressure at the filter hole 22 on the inner tub 2 is relatively small. The rotation of the ribs 4 can increase the speed at which the liquid in the second sub-cavity 212 is diverted to the filter hole 22.

[0054] The embodiment of the present invention also discloses a clothes processing device, such as Figure 1 As shown, the clothing processing device includes the barrel assembly described in any of the above embodiments. The outer barrel 1 is provided with a drainage hole, which can be set as one or more. The drainage hole connects the first cavity 11 and the outside of the outer barrel 1, and is used to discharge the liquid in the first cavity 11 to the outside of the outer barrel 1 to achieve a dehydration effect. In the embodiment of the present invention, the lint retained in the first cavity can be automatically discharged from the clothing processing device in the dehydrated state, and there is no need to manually disassemble and clean the filtering structure, which improves the convenience of filtering operation in the clothing processing device.

[0055] Reference Figure 1 , the filtering process of the clothes processing device is described below:

[0056] During the washing process of the clothes treatment device, the impeller 3 rotates relative to the inner barrel 2, and the ribs 4 at the bottom of the impeller 3 rotate with the impeller 3. The liquid in the second sub-chamber 212 is displaced by the ribs 4 and performs centrifugal motion, thereby pushing the liquid from the filter hole 22 into the first cavity 11, and driving the lint and other debris in the liquid into the first cavity 11. In this process, a large negative pressure is generated in the second cavity 21, which prompts the liquid in the first cavity 11 to flow from the first water hole 231 to the second cavity 21 to replenish the reduced water in the second cavity 21, thereby maintaining the water circulation of the entire clothes treatment device. In this process, since the cross-sectional area of ​​the first water hole 231 is smaller than the cross-sectional area of ​​the filter hole 22, the lint and other debris in the first cavity 11 cannot follow the liquid from the first water hole 231 back to the second cavity 21, so that the lint and other debris are continuously accumulated in the first cavity 11 during the entire washing process. When the impeller 3 stops rotating, the lint in the first cavity 11 will gradually settle to the bottom of the first cavity 11; when the clothing processing device is in a dehydrating state, the lint in the first cavity 11 will be automatically discharged from the drainage hole of the outer barrel 1 along with the liquid, without the need for a new filter, without residual dirt, and saving the user the inconvenience of cleaning the filter.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
