[0002] The existing pulsator washing machine without an outer drum adopts a combination of an inner drum and a water receiving tray to achieve washing and dehydration, but the inner drum of the washing machine without an outer drum is different from the inner drum structure of a traditional washing machine and has no drain port. Some people have proposed to design a drain port on the side wall of the inner drum, and to set a dehydration channel on the outer wall of the inner drum, wherein the inlet of the dehydration channel is connected with the drain port. When the inner drum is drained, the water in the inner drum moves upward along the inner wall of the inner drum and enters the dehydration channel through the drain port and the inlet of the dehydration channel, and then is discharged to the water receiving tray through the outlet of the dehydration channel.

[0043] <Dehydration channel components>

[0044] like Figure 1a , Figure 1b , Figure 2a and Figure 2b As shown, the present embodiment provides a dehydration flow channel assembly for a washing machine, the washing machine comprises an inner barrel 1 and a water receiving tray 5 arranged at the bottom of the inner barrel 1, the inner barrel 1 comprises an inner barrel outer wall 122 and an inner barrel inner wall 121; the inner barrel outer wall 122 is formed with a concave structure convex to the inner side of the inner barrel 1, a water through hole 111 is formed between the concave structure 11 and the inner barrel inner wall 121, and the water through hole 111 faces the circumferential direction of the inner barrel 1; a dehydration flow channel 2 is arranged on the outer side of the concave structure 11, the dehydration flow channel 2 occupies a small space, has a large space utilization rate, increases the capacity of the inner barrel 1, closely cooperates with the concave structure 11, has accurate positioning, reliable connection, and does not affect the overall appearance of the inner barrel 1; the dehydration flow channel 2 is connected with the water through hole 111, and when the inner barrel 1 is dehydrated, the water in the inner barrel 1 flows along the inner barrel inner wall 121 and along The inner barrel 1 moves upward in a circumferential spiral, smoothly enters the dehydration channel 2 through the water hole 111, and then is discharged to the water receiving tray 5, thereby achieving rapid drainage and high dehydration efficiency; preferably, the concave structure 11 extends along the axial direction of the inner barrel 1, and a water hole 111 is provided on each of the top of the concave structure 11 along the circumferential sides of the inner barrel 1; when the inner barrel 1 is accelerated and dehydrated at a uniform speed, the water in the inner barrel 1 moves upward along the inner wall 121 of the inner barrel under the action of centrifugal force, and its rotation speed is less than the rotation speed of the inner barrel 1 due to the influence of clothes and friction, and part of the water enters the dehydration channel 2 through the water hole 111 on the side opposite to the rotation direction of the inner barrel 1; when the inner barrel 1 decelerates, at a certain stage, the rotation speed of the water in the inner barrel 1 is greater than the rotation speed of the inner barrel 1, and part of the water enters the dehydration channel 2 through the water hole 111 on the side along the rotation direction of the inner barrel 1.

[0045] Further, if Figure 3a , Figure 3b , Figure 4a and Figure 4bAs shown, the dehydration channel 2 includes a dehydration channel inner wall 21 and a dehydration channel outer wall 22 matched with the outer wall 122 of the inner barrel; the inner concave structure 11, the dehydration channel inner wall 21 and the dehydration channel outer wall 22 are arranged in sequence from the inside to the outside along the radial direction of the inner barrel 1; specifically, the dehydration channel inner wall 21 is formed with a first profiling structure 211 matched with the inner concave structure 11, and the first profiling structure 211 also protrudes toward the inner side of the inner barrel 1 and is embedded in the outer side of the inner concave structure 11; the dehydration channel outer wall 22 is a smooth curved surface, and when it is covered on the dehydration channel inner wall 21, it is ensured that the dehydration channel outer wall 22 does not protrude much (within 4mm) from the outer wall 122 of the inner barrel, so as to achieve the purpose of increasing the diameter of the inner barrel 1 without occupying more space; the dehydration channel 2 is formed between the dehydration channel inner wall 21 and the dehydration channel outer wall 22, and the dehydration channel 2 extends along the axial direction of the inner barrel 1.

[0046] In order to allow the water discharged from the water through hole 111 to smoothly enter the dehydration channel 2 without backflow and to ensure the water output, a dehydration channel water inlet 213 is formed on the inner wall 21 of the dehydration channel at the water through hole 111, and the dehydration channel water inlet 213 faces the circumferential direction of the inner barrel 1 and is connected with the water through hole 111; specifically, a dehydration channel water inlet 213 is provided on the top of the inner wall 21 of the dehydration channel along both sides of the circumference of the inner barrel 1, and the two dehydration channel water inlets 213 correspond to the two water through holes 111 respectively; when the inner barrel 1 is dehydrated, the water in the inner barrel 1 flows along the inner side wall 121 of the inner barrel and spirals upward along the circumference of the inner barrel 1, enters the dehydration channel 2 through the water through hole 111 and the dehydration channel water inlet 213, and then is discharged along the dehydration channel 2.

[0047] In order to allow the water entering the dehydration channel 2 to be discharged smoothly and quickly, a dehydration channel outlet 23 is formed at the bottom of the dehydration channel 2, and the flow area of ​​the dehydration channel 2 gradually increases downward along the dehydration channel 2; when the inner barrel 1 is dehydrated, the water entering the dehydration channel 2 can be quickly discharged from the dehydration channel outlet 23 due to the large flow area and reduced pressure. When the gap between the inner barrel 1 and the water receiving tray remains unchanged, the probability of water being thrown out of the water receiving tray is effectively reduced.

[0048] Preferably, the outer wall 22 of the dehydration channel is formed with a bulge 221 protruding toward the outside of the inner barrel 1 at the dehydration channel outlet 23, and the flow area of ​​the bulge 221 gradually increases downward along the dehydration channel 2; specifically, the dehydration channel outlet 23 is higher than the lowest point of the inner barrel base 13 and lower than the top edge of the water receiving tray.

[0049] like Figure 3a , Figure 3b , Figure 4a and Figure 4bAs shown, in order to prevent water from flowing out of the gap between the inner wall 21 of the dehydration channel and the outer wall 122 of the inner barrel when the inner barrel 1 is dehydrated, the dehydration channel assembly also includes a sealing structure 3, which includes a sealing ring 31 and a sealing sheet 32 ​​adapted to the water hole 111; the sealing ring 31 is arranged between the inner wall 21 of the dehydration channel and the outer wall 122 of the inner barrel, and is used to seal the gap between the inner wall 21 of the dehydration channel and the outer wall 122 of the inner barrel; specifically, the sealing ring 31 includes a sealing strip 311 arranged on the left and right edges of the inner wall 21 of the dehydration channel and a sealing strip 312 arranged on the inner wall 21 of the dehydration channel. A sealing groove 312 is formed on the top of the inner wall 21 of the dehydration channel, and the sealing groove 312 is sleeved on the top of the inner wall 21 of the dehydration channel; two water outlets 321 are formed at the sealing sheet 32 ​​corresponding to the water through hole 111, and the sealing sheet 32 ​​is arranged between the water through hole 111 and the water inlet 213 of the dehydration channel. The two water outlets 321 correspond to the two water through holes 111, and are used to seal the gap between the water through hole 111 and the water inlet 213 of the dehydration channel to prevent water from flowing out from the gap between the water through hole 111 and the water inlet 213 of the dehydration channel when the inner barrel 1 is dehydrated and thrown onto parts such as the washing machine body.

[0050] In order to make the seal reliable and ensure the accuracy of the positioning between the sealing structure 3 and the inner wall 21 of the dehydration channel, the sealing structure 3 also includes a sealing positioning column 33. Specifically, a plurality of sealing positioning columns 33 are formed along the extension direction of the sealing strip 311, and the sealing sheet 32 ​​is formed with a plurality of sealing positioning columns 33 around the sealing groove 312. Correspondingly, the inner wall 21 of the dehydration channel and the outer wall 22 of the dehydration channel are both formed with sealing positioning holes 24. When installing the sealing structure 3, the sealing structure 3, the inner wall 21 of the dehydration channel and the outer wall 22 of the dehydration channel are sequentially arranged from the inside to the outside along the radial direction of the inner barrel 1, and the sealing positioning columns 33 sequentially pass through the sealing positioning holes 24 of the inner wall 21 of the dehydration channel and the sealing positioning holes 24 of the outer wall 22 of the dehydration channel to realize the positioning of the sealing structure 3.

[0051] In order to ensure that the dehydration channel 2 is reliably connected to the outer wall 122 of the inner barrel, an inner barrel mounting hole 14 is formed on the side wall of the inner barrel 1, a sealing mounting hole 34 is formed on the sealing structure 3, a dehydration channel inner wall mounting hole 212 is formed on the dehydration channel inner wall, and a dehydration channel outer wall mounting hole 222 is formed on the dehydration channel outer wall; when installing the dehydration channel 2, the inner barrel mounting hole 14, the sealing mounting hole 34, the dehydration channel inner wall mounting hole 212 and the dehydration channel outer wall mounting hole 222 correspond to each other, and are connected by screws to achieve the fixation of the dehydration channel 2 to the outer wall 122 of the inner barrel.

[0052] It should be noted that the material of the dehydration channel inner wall 21 and the dehydration channel outer wall 22 is not limited, and can be non-metallic materials (such as rubber, plastic). Correspondingly, the sealing method can be hot melt welding or applying sealant; the material of the dehydration channel inner wall 21 and the dehydration channel outer wall 22 can also be metal material, and correspondingly, the sealing method can be buckling, riveting, and gluing.

[0053] like Figure 5a , Figure 5b , Figure 6a and Figure 6b As shown, the dehydration flow channel assembly also includes a wire scrap collecting component 4 arranged on the inner side wall 121 of the inner barrel; the wire scrap collecting component includes a wire scrap collector base 41, and the wire scrap collector base 41 is formed with a second profiling structure 411 adapted to the concave structure 11, and the second profiling structure 411 also protrudes toward the inner side of the inner barrel 1 and covers the inner side of the concave structure 11, thereby ensuring the accuracy of positioning of the wire scrap collecting component 4 and the concave structure 11 and the tightness of installation.

[0054] A mounting column 412 is formed on the side of the inner wall 121 of the inner barrel of the wire chip collector base 41. When the dehydration channel 2 and the wire chip collecting component 4 are installed, the first profiling structure 211 of the inner wall 21 of the dehydration channel is arranged on the outer side of the concave structure 11, and the second profiling structure 411 of the wire chip collector base 41 is arranged on the inner side of the concave structure 11 to achieve quick alignment. The inner barrel mounting hole 14, the sealing mounting hole 34, the dehydration channel inner wall mounting hole 212, the dehydration channel outer wall mounting hole 222 and the mounting column 412 of the wire chip collector base 41 correspond to each other, and the wire chip collector base 41, the side wall of the inner barrel 1, the sealing structure 3, the dehydration channel inner wall 21 and the dehydration channel outer wall 22 are fixed together by screws.

[0055] In order to allow the water in the inner barrel 1 to smoothly enter the dewatering channel 2 through the water hole 111 and ensure the water output, a cavity is formed on the top of the wire scrap collector base 41 around the water hole 111; the cavity has a cavity water inlet 414, which faces the circumferential direction of the inner barrel 1 and is connected to the inner barrel 1; specifically, a cavity 413 is provided on each side of the top of the wire scrap collector base 41 along the circumferential direction of the inner barrel 1, and the side of the cavity 413 is provided around the water hole The retaining rib 411 is at the retaining rib 415, and one side of the retaining rib 415 is opened to form a cavity water inlet 414, so that the cavity water inlet 414 becomes the only water inlet for the water in the inner barrel 1 when the inner barrel 1 is drained. The retaining rib 415 prevents the water entering the cavity 413 from flowing out, ensuring that the water in the inner barrel 1 smoothly enters the dehydration channel 2; when the inner barrel 1 is dehydrated, the water in the inner barrel 1 enters the cavity 413 through the cavity water inlet 414, and under the action of the retaining rib 415, the water enters the dehydration channel 2 through the water hole 111.

[0056] In order to prevent the clothes from blocking the cavity water inlet 414 when the inner tub 1 is drained, a clothes blocking net 416 is formed at the cavity water inlet 414 to prevent the clothes from entering the dehydration flow channel 2.

[0057] In order to prevent the wire scraps in the water from clogging the dehydration channel 2, the wire scrap collection component 4 also includes a wire scrap collector 42 and a filter screen 43. Correspondingly, the wire scrap collector base 41 is formed with a first installation position for setting the wire scrap collector 42 and a second installation position for setting the filter screen 43; from the radial direction of the inner barrel 1 from the inside to the outside, the filter screen 43, the wire scrap collector 42 and the wire scrap collector base 41 are sequentially arranged; the wire scrap collector 42 and the wire scrap collector base 41 are connected with a detachable structure for easy disassembly; the wire scrap collector 42 is fixed at the first installation position, and the filter screen 43 is fixed at the second installation position.

[0058] The lint collector base 41 is formed with a plurality of collector inlets on both sides along the circumference of the inner barrel 1. When the inner barrel 1 rotates, the water in the inner barrel 1 enters the lint collector 42 through the collector inlet 417. When the water flows through the filter 43, the lint therein is intercepted by the filter 43, thereby achieving the purpose of filtering the lint in the water. The lint is collected in the lint collector 42.

[0061] In some embodiments, the pulsator washing machine also includes a water collecting tray 5 arranged at the bottom of the inner barrel; when the inner barrel 1 is dehydrated, the water in the inner barrel 1 enters the cavity 413 through the cavity water inlet 414, and then enters the dehydration channel 2 through the water hole 111 and the dehydration channel water inlet 213, and is discharged to the water collecting tray 5 through the dehydration channel water outlet 23.
