For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0035] See also Figures 1 to 6 , an embodiment of the present application provides a washing drum assembly.
[0036] An embodiment of the present application provides a clothes processing device, including a water tub and a washing drum assembly according to any embodiment of the present application.
[0037] It should be noted that the specific type of the clothing processing device is not limited. For example, the clothing processing device can be a drum washing machine, a washer-dryer, etc.
[0038] The water tub is used to hold water required for washing clothes, and the washing tub assembly is rotatably disposed in the water tub, that is, the washing tub assembly can be disposed in the water tub in a forward or reverse rotation.
[0039] The washing tub assembly includes a washing tub 10 and a support frame 11 .
[0040] The washing tub 10 is used to hold clothes, and the water tub is mounted outside the washing tub 10. Exemplarily, holes are provided on the side wall of the washing tub 10, and water in the water tub can enter the washing tub 10 through the holes of the washing tub 10 to wash the clothes in the washing tub 10.
[0041] The washing tub 10 comprises a tub body and a rear cover 101. The rear cover 101 is arranged at one end of the tub body, and the two define a laundry processing chamber.
[0042] Specifically, the front end of the barrel is open to form a clothing delivery opening, and the rear end cooperates with the rear cover 101. For example, the rear end of the barrel can be detachably connected to the rear cover 101. The barrel and the rear cover 101 together define a clothing processing cavity, and the user can put clothing into the clothing processing cavity or take clothing out of the clothing processing cavity through the clothing delivery opening.
[0043] The support frame 11 is disposed on a side of the rear cover 101 facing away from the laundry processing chamber, that is, the support frame 11 is disposed on the rear side of the rear cover 101 .
[0044] It is understandable that the support frame 11 can be in contact with the side of the rear cover 101 away from the clothing processing chamber. For example, in some embodiments, the support frame 11 can be connected to the rear cover 101 by fasteners such as screws. In other embodiments, the support frame 11 and the rear cover 101 can also be connected together by rivets or welding. Of course, the support frame 11 can also be spaced apart from the side of the rear cover 101 away from the clothing processing chamber, and the support frame 11 and the rear cover 101 can be connected together by other structures.
[0045] During washing, the support frame 11 can rotate synchronously with the washing tub 10, that is, the rotation axis of the washing tub 10 coincides with the rotation axis of the support frame 11. Of course, the support frame 11 can also provide force support for the rear cover 101, increasing the structural stability of the washing tub assembly.
[0046] See also Figure 3 and Figure 4 The support frame 11 includes a plurality of support arms 111. The plurality of support arms 111 are generally distributed in a radial shape.
[0047] See also Figure 4 The support arm 111 has a flow channel 111a and a water intake port 111b. Figure 1 The rear cover 101 has a spray port 101a, and a flow channel 111a connects the spray port 101a and a water inlet 111b. The water inlet 111b is suitable for scooping liquid into the flow channel 111a during the rotation of the washing drum assembly. The liquid can be water or a mixture of water and detergent.
[0048] The flow channel 111a is used to guide the liquid scooped from the water inlet 111b to the spray port 101a, and the spray port 101a is used to spray the liquid into the washing tub 10. Specifically, taking one of the support arms 111 as an example, when the washing tub assembly rotates, when the support arm 111 is at a lower position, the water inlet 111b scoops the liquid into the flow channel 111a, and as the position of the support arm 111 rises, the liquid in the flow channel 111a enters the spray port 101a along the flow channel 111a under the action of gravity, and then flows into the washing tub 10 through the spray port 101a to wet the clothes. It can be seen that in the washing tub assembly of the embodiment of the present application, the support frame 11 scoops water during the rotation process and guides the water by gravity, so there is no need to set up an additional power device.
[0049] The water intake 111b of at least one part of the support arm 111 is located on the water-facing side along the first rotation direction, and the water intake 111b of another part of the support arm 111 is located on the water-facing side along the second rotation direction, wherein the first rotation direction and the second rotation direction are opposite.
[0050] It should be noted that the water-facing side refers to the side facing the direction of rotation. Specifically, the water intake 111b on the water-facing side can face the liquid head-on, and the liquid is scooped up by the water intake 111b and enters the flow channel 111a. For example, when the washing drum assembly rotates along the first rotation direction, the water intake 111b of a part of the support arm 111 is located on the water-facing side along the first rotation direction. This part of the water intake 111b can scoop up the liquid into the flow channel 111a and spray it out from the spray port 101a. The water intake 111b of another part of the support arm 111 is located on the back water side along the first rotation direction. This part of the water intake 111b cannot scoop up the liquid or the liquid flows out of the water intake 111b under the action of gravity after entering the water intake 111b and cannot enter the flow channel 111a. In this example, the liquid is scooped up through the water intake 111b located on the water-facing side of the first rotation direction. When the washing drum assembly rotates along the second rotation direction, the water inlet 111b located on the water-facing side of the first rotation direction is located on the water-receiving side of the second rotation direction. This part of the water inlet 111b cannot scoop up liquid, or after the liquid enters the water inlet 111b, it flows out from the water inlet 111b under the action of gravity and cannot enter the flow channel 111a. The water inlet 111b located on the water-receiving side of the first rotation direction is located on the water-facing side of the second rotation direction. This part of the water inlet 111b can scoop up liquid into the flow channel 111a and spray it out from the spray port 101a. In this example, the liquid is scooped through the water inlet 111b located on the water-facing side of the second rotation direction.
[0051] It should be noted that the first rotation direction and the second rotation direction are both rotation directions of the washing drum assembly in the water tub, and the first rotation direction and the second rotation direction correspond to the forward and reverse rotation of the washing drum assembly, and the forward and reverse rotation are relative, that is, the washing drum assembly rotates in one direction of the first rotation direction and the second rotation direction is forward rotation, and the washing drum assembly rotates in the other rotation direction of the first rotation direction and the second rotation direction is reverse rotation.
[0052] For example, in some embodiments, Figures 1 to 6 The clockwise direction is defined as the first rotation direction, and the counterclockwise direction is defined as the second rotation direction. Figures 1 to 6 The counterclockwise direction is defined as the first rotation direction, and the clockwise direction is defined as the second rotation direction.
[0053] In the present application embodiment, Figure 5 The clockwise direction indicated by the arrow is the first rotation direction. Figure 6 The counterclockwise direction indicated by the arrow is described as the second rotation direction.
[0054] It is understandable that during the laundry process, the washing tub assembly operates alternately in forward and reverse directions so that the laundry in the washing tub 10 rubs against each other, thereby increasing the washing effect and also reducing the chance of the laundry becoming entangled.
[0055] The following briefly describes the working process of the washing drum assembly by taking a drum washing machine as an example of the clothes processing device.
[0056] When washing clothes, the liquid in the washing tub 10 flows out to between the water tub and the washing tub 10 , wherein the liquid in the washing tub 10 can flow to between the water tub and the washing tub 10 through the holes on the side wall of the washing tub 10 .
[0057] When the washing drum assembly rotates in the first rotation direction, the support frame 11 rotates synchronously with the washing drum 10. When the water inlet 111b located on the water-facing side of the first rotation direction is submerged in the liquid, the water inlet 111b scoops up the liquid. As the washing drum assembly continues to rotate, the water inlet 111b rises, and the scooped liquid is guided to the spray port 101a along the flow channel 111a under the action of gravity, and then returns to the washing drum 10 through the spray port 101a, thereby shortening the soaking time of the clothes and improving the utilization rate of the detergent. Similarly, when the washing drum assembly rotates in the second direction, the water inlet 111b located on the water-facing side of the second rotation direction is submerged in the liquid, scoops up the liquid, and guides the liquid to the spray port 101a along the flow channel 111a under the action of gravity, and returns to the washing drum 10 through the spray port 101a, thereby shortening the soaking time of the clothes. In this way, no matter the washing drum assembly rotates in the first rotation direction or the second rotation direction, the corresponding water inlet 111b can take water to achieve spraying, thereby improving the utilization rate of detergent, washing uniformity, cleaning degree and washing efficiency.
[0058] The washing drum assembly provided in the embodiment of the present application has a water intake port 111b that can scoop up liquid when the washing drum assembly rotates forward or reversely, thereby realizing continuous scooping and continuous water guiding, and the water intake efficiency is high. The liquid is guided to the spray port 101a through the flow channel 111a under the action of gravity, and is sprayed back into the washing drum 10 through the spray port 101a to moisten the clothes. In this way, the support frame 11 can continuously supply water to the spray port 101a when the washing drum assembly rotates forward or reversely, thereby improving the continuity and amount of spraying, further shortening the wetting time of clothes, and improving the washing rate and washing effect. In addition, the washing drum 10 rotates synchronously with the support frame 11, and uses gravity to realize the circulating spraying of the liquid. There is no need to set up an additional power device such as a circulating pump to drive the support frame 11, thereby reducing the power consumption cost.
[0059] The number of the support arms 111 is not limited, and may be two, three, or more than three.
[0060] For some examples, see Figure 5 and Figure 6 , the number of support arms 111 is an even number. Each support arm 111 includes at least one first support arm 111' and at least one second support arm 111", wherein the water intake 111b of the first support arm 111' is located on the water-facing side along the first rotation direction, and the water intake 111b of the second support arm 111" is located on the water-facing side along the second rotation direction.
[0061] That is to say, for the convenience of description, the support arm 111 with the water intake 111b located on the waterfront side along the first rotation direction is recorded as the first support arm 111', and the support arm 111 with the water intake 111b located on the waterfront side along the second rotation direction is recorded as the second support arm 111".
[0062] The arrangement of the first support arm 111 ′ and the second support arm 111 ″ is not limited.
[0063] Exemplarily, the first support arm 111' and the second support arm 111" are alternately arranged along the circumferential direction. It should be noted that the first support arm 111' and the second support arm 111" are alternately arranged along the circumferential direction, which means that along the circumference of the back cover 101 or the support frame 11, the second support arms 111" are arranged on both adjacent sides of any first support arm 111', and the first support arms 111' are arranged on both adjacent sides of any second support arm 111".
[0064] It can be understood that when the washing drum assembly rotates along the first rotation direction, the water inlet 111b of the second support arm 111" is located on the backwater side of the first rotation direction, and only the water inlet 111b of the first support arm 111' can smoothly take water. When the water inlet 111b of the first support arm 111' is submerged in liquid, the water inlet 111b of the first support arm 111' scoops up the liquid, and the scooped liquid is guided to the spray port 101a along the flow channel 111a under the action of gravity, and then returns to the washing drum through the spray port 101a. 10. When the washing tub assembly rotates along the second rotation direction, the water inlet 111b of the first support arm 111' is located on the backwater side of the second rotation direction, and only the water inlet 111b of the second support arm 111" can smoothly take water. When the water inlet 111b of the second support arm 111" is submerged in liquid, the water inlet 111b of the second support arm 111" scoops up the liquid, and the scooped liquid is guided to the spray port 101a along the flow channel 111a under the action of gravity, and then returns to the washing tub 10 through the spray port 101a.
[0065] In this embodiment, the first support arm 111' and the second support arm 111" are alternately arranged. When the washing drum assembly rotates along the first rotation direction or the second rotation direction, the corresponding water intake port 111b can scoop up approximately the same amount of water, so that the spraying amount is also approximately the same, thereby increasing the uniformity of spraying and thus improving the washing efficiency. In addition, the alternating arrangement of the first support arm 111' and the second support arm 111" along the circumferential direction can also improve the force uniformity of each support arm 111 and the coordination of the flow diversion of the flow channel 111a corresponding to each support arm 111, thereby better achieving a continuous spraying effect.
[0066] It should be noted that the number of the support arms 111 is not limited, and may be two, four, six, etc. For example, in some examples, see Figure 5 and Figure 6The number of support arms 111 is six, the number of first support arms 111' is three, and the number of second support arms 111" is three. In this way, when the washing drum assembly has approximately the same water intake along the first rotation direction and the second rotation direction, the arrangement of multiple first support arms 111' and second support arms 111" can also increase the water intake efficiency of the support arms 111 and shorten the soaking time of clothes.
[0067] In some embodiments, the flow channels 111a of each support arm 111 are not connected to each other, that is, when the water intake port 111b of one of the support arms 111 scoops up liquid, the liquid flows along the flow channel 111a of the support arm 111 to the spray port 101a, and is sprayed out through the spray port 101a, and does not flow to the flow channels 111a of other support arms 111. In this way, each support arm 111 can smoothly intake water and enable all the liquid in the flow channel 111a to flow to the spray port 101a, thereby reducing the probability of liquid flowing back to other flow channels 111a and increasing water intake reliability. In addition, the water intake of each support arm 111 can also not affect each other, thereby increasing the water intake reliability of the support frame 11 when the washing drum assembly rotates in the first rotation direction and the second rotation direction.
[0068] The installation positions of the water inlet 111b and the spray port 101a are not limited.
[0069] For example, see Figures 1 to 6 The water inlet 111b is arranged near the outer periphery of the rear cover 101, the spray port 101a is arranged at the center of the rear cover 101, and the flow channel 111a extends along the radial direction of the rear cover 101. In this way, on the one hand, it is convenient for the water inlet 111b to scoop water and the flow channel 111a to guide the water to the spray port 101a by gravity. On the other hand, the spray port 101a sprays water from the center of the rear cover 101 toward the clothes in the washing tub 10, which can increase the wetting effect on the clothes.
[0070] For some examples, see Figure 2 In a plane perpendicular to the rotation axis of the support arm 111, the angle α1 between the tangent at the water intake 111b and the reference line e does not exceed 15°, that is, α1≤15°, for example, 15°, 13.5°, 12°, 10°, 9°, 8°, 6°, 3°, 2°, 1°, etc., wherein the reference line e is a straight line passing through the rotation center of the support frame 11 and the center of the water intake 111b.
[0071] In this embodiment, the angle setting of the water intake port 111b and the reference line makes it easy for the water intake port 111b to scoop up liquid, and at the same time, more support arms 111 can be arranged without increasing the circumferential size of the washing drum assembly, thereby increasing the water intake amount of the washing drum assembly, increasing the water spraying efficiency, and also increasing the structural compactness of the washing drum assembly.
[0072] The specific structure of the support arm 111 is not limited.
[0073] For some examples, see Figures 2 to 4 The support arm 111 includes two side plates 1111, the flow channel 111a is located between the two side plates 1111, the water inlet 111b is set on one of the side plates 1111, and the side of the side plate 1111 away from the flow channel 111a has a rib 1112, and the rib 1112 extends along the edge of the side plate 1111.
[0074] Specifically, the space between the two side plates 1111 defines a flow channel 111a. When the water inlet 111b scoops up liquid, it can directly enter the flow channel 111a between the two side plates 1111, thereby increasing the utilization rate of the liquid. The ribs 1112 can increase the structural strength of the support arm 111.
[0075] For some examples, see Figure 3 and Figure 4 The ribs 1112 extend continuously along the edge of the side plate 1111, and a water storage tank 1112a is arranged on the surface of the side plate 1111. The water storage tank 1112a of the support arm 111 is connected to the water inlet 111b.
[0076] Specifically, when the water intake port 111b scoops up liquid, the water storage tank 1112a connected to the water intake port 111b can also store liquid, and the liquid enters the flow channel 111a through the water intake port 111b, so that the water intake port 111b can scoop up more liquid at a time, thereby increasing the water intake efficiency, thereby ensuring the spraying amount of the spray port 101a and increasing the washing efficiency. The water storage tank 1112a is defined by the space within the rib 1112, which can also make the structure of the support frame 11 simpler.
[0077] It should be noted that the convex rib 1112 extends continuously along the edge of the side plate 1111 , which means that the convex rib 1112 has no notch or is not cut or disconnected by other structures, and the edge refers to the edge around the side plate 1111 .
[0078] It should be noted that the convex rib 1112 enclosing a water tank 1112a on the surface of the side plate 1111 means that the inner wall of the convex rib 1112 encloses a water tank 1112a on the side of the side plate 1111 away from the flow channel 111a, and the side of the water tank 1112a away from the side plate 1111 is open to scoop water.
[0079] For some examples, see Figure 2 In a plane perpendicular to the rotation axis of the support frame 11 , the rib 1112 defines a contour shape of the support arm 111 . Figure 2 The viewing angle shown is the viewing angle of a plane perpendicular to the rotation axis of the support frame 11 .
[0080] Thus, the structure of the support arm 111 is relatively simple, which reduces the manufacturing difficulty.
[0081] For some examples, see Figure 2 , the sum of the circumferential widths L1+L3 of the ribs 1112 on both sides of the support arm 111 does not exceed the circumferential width L2 of the flow channel 111a, that is, L1+L3≤L2.
[0082] In this way, the flow channel 111a of the support arm 111 can have enough space for the liquid scooped up by the water intake 111b to flow, thereby increasing the amount of liquid that the support arm 111 can extract at a single time. The rib 1112 increases the structural strength of the support arm 111 without occupying too much installation space, making the structure of the single support arm 111 more reasonable and compact.
[0083] It should be noted that when comparing the width of the flow channel 111a and the width of the rib 1112, the premise is to compare the dimensions of the two on the same circumference, and not on different circumferences. Figure 2 , L1, L2, and L3 are the width dimensions of the rib 1112 and the flow channel 111a along the circumference R. The circumference R is a circle that extends outward from the rotation center of the support frame 11 and intersects with the support arm 111. Taking one of the support arms 111 as an example, L1 is the distance between the two intersection points of the circumference R and the rib 1112 and the side plate 1111 located on one side of the support arm 111, and L3 is the distance between the two intersection points of the circumference R and the rib 1112 and the side plate 1111 located on the other side of the support arm 111. L1 and L3 are the circumferential widths of the rib 1112, L2 is the distance between the intersection points of the circumference R and the side plates 1111 on both sides, and L2 is the circumferential width of the flow channel 111a.
[0084] It should be noted that Figure 2 Only one circumference R is shown, and the widths of the flow channel 111a and the convex rib 1112 at the position corresponding to the circumference R are shown. It can be understood that when it is necessary to compare the widths of the flow channel 111a and the convex rib 1112 at other positions, a circumference can be abstractly drawn at the position to be compared, and then the widths of the two on the circumference can be compared.
[0085] It is understandable that the circumferential dimensions of the two ribs 1112 of a single support arm 111 may be the same or different, and there is no limitation thereto. For example, in some examples, the circumferential widths of the two ribs 1112 of a single support arm 111 are the same; in other embodiments, the circumferential width of the rib 1112 connected to the water intake port 111b is greater than the circumferential width of the rib 1112 on the other side. In this way, the area of the water storage tank 1112a defined by the rib 1112 connected to the water intake port 111b can also be larger, thereby increasing the content of liquid stored therein and thus increasing the water intake efficiency.
[0086] For some examples, see Figure 2 The side plate 1111 includes a first portion 1111a and a second portion 1111b, and the second portion 1111b is connected to an end of the first portion 1111a away from the rotation axis of the support frame 11; that is, the second portion 1111b is arranged away from the rotation axis of the support frame 11.
[0087] Along the direction away from the rotation axis of the support frame 11 , the second portions 1111 b of the two side plates 1111 of the support arm 111 extend obliquely in the direction away from each other.
[0088] In this way, on the one hand, the liquid entering the second part 1111b from the water intake port 111b can have sufficient circulation space, thereby increasing the amount of liquid entering the second part 1111b, and when the water intake port 111b is raised as the washing drum assembly rotates, the second part 1111b can also play a guiding role, guiding the liquid to the first part 1111a, and then to the spray port 101a, and, along the direction close to the first part 1111a, the second part 1111b extends obliquely in the direction close to each other, which can also increase the flow rate of the liquid from the second part 1111b into the first part 1111a, increase the ability of the support arm 111 to gather liquid, and thus improve the water intake rate.
[0089] See also Figure 2 The included angle α2 of the second parts 1111b of the two side panels 1111 is 10°~40°, 10°≤α2≤40°, for example, 10°, 12°, 15°, 17°, 20°, 24°, 27°, 30°, 33°, 36°, 39°, 40°, etc.
[0090] It should be noted that the angle α2 is the angle between the extension directions of the second parts 1111 b of the two side plates 1111 .
[0091] The setting of the angle between the two second parts 1111b of the support arm 111, on the one hand, can facilitate sufficient liquid to enter the first part 1111a through the second part 1111b, and on the other hand, can also reduce the maximum circumferential size of a single support arm 111, thereby facilitating the arrangement of multiple support arms 111, making the structure of the support frame 11 more compact, and increasing the number of support arms 111 that scoop water when the washing drum assembly rotates along the first rotation direction or the second rotation direction, further increasing the water intake efficiency and improving the washing effect.
[0092] The flow channel 111 a is formed in any manner.
[0093] In some embodiments, the flow channel 111 a is open toward one side of the rear cover 101 , and the rear cover 101 closes the opening of the flow channel 111 a .
[0094] That is to say, in the present embodiment, the support frame 11 is in contact with the rear cover 101, and the rear cover 101 closes the flow channel 111a toward the side of the rear cover 101, so that the liquid entering the flow channel 111a from the water intake 111b can flow toward the spray port 101a, and will not flow out through the gap between the flow channel 111a and the rear cover 101. In addition, by closing the flow channel 111a through the cooperation between the support frame 11 and the rear cover 101, the overall size of the support frame 11 along the axial direction of the washing drum assembly can also be reduced.
[0095] Of course, in some embodiments, a seal is also provided between the support frame 11 and the back cover 101. The seal is provided along the edge of one side where the flow channel 111a is opened. When the support frame 11 and the back cover 101 are matched, the seal is clamped between the support frame 11 and the back cover 101. In this way, the sealing effect and sealing reliability of the flow channel 111a are improved, and the probability of liquid leakage in the flow channel 111a during the diversion process is reduced.
[0096] In other embodiments, the support arm 111 alone defines a closed flow channel 111 a.
[0097] It should be noted that the closed flow channel 111a means that the flow channel 111a is only indirectly connected to the outside world through the water intake 111b and the spray port 101a, and the flow channel 111a itself is not directly connected to the outside world. The liquid entering the flow channel 111a from the water intake 111b will only flow out from the spray port 101a, and will not flow from the flow channel 111a to the outside world.
[0098] In this embodiment, the flow channel 111a is defined by the structure of the support arm 111 itself, and the liquid can be directed to the spray port 101a without cooperating with other structures, thereby increasing the sealing reliability of the flow channel 111a and making the connection between the support frame 11 and the back cover 101 simpler.
[0099] For some examples, see Figure 3The support frame 11 includes a core 112 , and one end of each support arm 111 is connected to the core 112 , that is, one end of the support arm 111 away from the water intake 111 b is connected to the core 112 .
[0100] See also Figure 1 The rear cover 101 has a water outlet cover portion 1011, the edge cover of the water outlet cover portion 1011 is arranged on one side of the core portion 112, and a plurality of unconnected guide areas are defined between the two, and a spray port 101a is provided at a position corresponding to each guide area of the water outlet cover portion 1011, and the end of each flow channel 111a along the flow direction extends to the guide area corresponding to the core portion 112.
[0101] It should be noted that the multiple unconnected guide areas refer to that each guide area guides independently, and the liquid in each guide area will not flow mutually. The guide area is used to guide the liquid flowing into the core 112 to the corresponding spray port 101a.
[0102] That is to say, each flow channel 111a guides the liquid to the corresponding guide area, and then the guide area guides the liquid to the corresponding spray port 101a, and the spray port 101a sprays the liquid into the washing drum 10. In this embodiment, each flow channel 111a, guide area, and spray port 101a work independently, which can reduce the probability of mutual interference between fluids, increase the guide reliability and spray reliability, and thus improve the washing efficiency.
