Description

Technical Field

[0001] This utility model relates to the field of clothing processing technology, and in particular to a pulsator washing machine. Background Technology

[0002] Top-loading washing machines are clothing processing devices that use electrical energy to generate mechanical rotation to wash clothes, and they are very common.

[0003] Related pulsator washing machines typically include a casing and a tub assembly located within the casing. The tub assembly includes an outer tub and a washing tub located within the outer tub, with a washing chamber inside the washing tub.

[0004] During the washing process, clothes often experience color fading. Washing different colors or light and dark colors together can easily lead to color bleeding and the embarrassing problem of color transfer. To solve this problem, people usually add color-blocking sheets (also known as color-protecting sheets). These sheets quickly absorb the color that has been washed off the clothes, thus protecting the color and preventing color bleeding. However, existing color-blocking sheets generally require manual addition, which is inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a pulsator washing machine to solve the problem of automatic dispensing of anti-color-crossing sheets.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] According to one aspect of the present invention, a pulsator washing machine is provided, comprising: a casing, the casing being configured as an outer shell of the pulsator washing machine, the top of the casing having a clothes inlet; a tub assembly disposed within the casing, the tub assembly forming a washing chamber, the top of the tub assembly having a tub opening communicating with the washing chamber, the clothes inlet being arranged vertically opposite to and communicating with the tub opening; a clothes dispensing device disposed at the top of the casing and above the tub opening; the clothes dispensing device comprising: a receiving cavity, the receiving cavity being used to place an anti-color-crossing sheet, the bottom of the receiving cavity having a clearance opening; and a roller rotatably disposed at the clearance opening, the roller being used to interact with the anti-color-crossing sheet located at the bottom of the receiving cavity. The bottom surfaces of the color-crossing sheets abut against each other; baffles are spaced apart on one side of the roller, with the upper end of the baffles extending into the receiving cavity and located on one side of the anti-color-crossing sheet; a dispensing gap is provided between the baffles and the roller, with the bottom end of the dispensing gap facing and communicating with the bucket opening; a drive motor is connected to the roller and is used to drive the roller to rotate; wherein, when the drive motor drives the roller to rotate, the roller can roll and rub against the bottom surface of the anti-color-crossing sheet located at the bottom of the receiving cavity, thereby driving the anti-color-crossing sheet to move towards the baffle, so that the anti-color-crossing sheet abuts against the baffle and enters the dispensing gap, and then falls down along the dispensing gap into the bucket opening and the washing cavity.

[0008] The above-mentioned technical solution has the following advantages or beneficial effects: Through the cooperative structure of the drive motor, roller, and baffle, the anti-color-crossing sheets can be automatically dispensed one by one, improving ease of use. Specifically, when the drive motor drives the roller to rotate, the roller can roll and rub against the bottom surface of the anti-color-crossing sheet located at the bottom of the receiving cavity, causing the anti-color-crossing sheet to move towards the baffle, so that the anti-color-crossing sheet abuts against the baffle and enters the dispensing gap, then falls down along the dispensing gap into the tub opening and washing cavity, realizing the automatic dispensing function of the anti-color-crossing sheet. The rolling friction between the roller and the anti-color-crossing sheet acts as a thrust, driving the anti-color-crossing sheet to move. Combined with the blocking effect of the baffle, the bottom anti-color-crossing sheet separates from the anti-color-crossing sheets stacked above it, thus realizing the sequential dispensing of the anti-color-crossing sheets.

[0009] In some embodiments of this application, a support rib is provided on each of the opposite sides of the bottom end of the accommodating cavity, the two support ribs are arranged at intervals and opposite to each other, and the clearance is formed between the two support ribs; the two ends of the anti-color-crossing sheet are respectively supported on one of the support ribs.

[0010] The above technical solution has the following advantages or beneficial effects: by arranging two support ribs at intervals relative to each other, the two ends of the anti-color-crossing sheet can be supported on a support rib respectively, so that multiple anti-color-crossing sheets can be stacked on the two support ribs in sequence, and multiple anti-color-crossing sheets can be stably placed in the accommodating cavity.

[0011] In some embodiments of this application, the receiving cavity is disposed on the outer periphery of the clothing inlet, the baffles are spaced apart on the side of the roller near the clothing inlet, the upper end of the baffles is arranged on the side of the anti-color-crossing sheet near the clothing inlet, and the lower end of the baffles is disposed below the clearance opening and extends toward the side near the clothing inlet.

[0012] The above-mentioned technical solution has the following advantages or beneficial effects: By rotating the roller, the anti-color-bleeding sheet can be moved towards the side closest to the clothing inlet, causing it to move towards the baffle. This allows the anti-color-bleeding sheet to abut against the baffle and enter the feeding gap from the side of the clearance opening closest to the clothing inlet, subsequently falling downwards into the tub opening and washing chamber. Furthermore, the lower end of the baffle extends towards the side closest to the clothing inlet, ensuring that after the anti-color-bleeding sheet abuts against the baffle, its end can smoothly enter the feeding gap downwards along the surface of the baffle.

[0013] In some embodiments of this application, the baffle extends in an arc shape toward the side closer to the clothing inlet.

[0014] The above technical solution has the following advantages or beneficial effects: the surface of the baffle facing the roller can form an arc-shaped surface. When the roller drives the anti-color-crossing sheet to move, and the anti-color-crossing sheet comes into contact with the baffle, the end of the anti-color-crossing sheet can smoothly enter the dispensing gap along the arc-shaped surface of the baffle, and then fall down into the bucket opening and washing chamber along the dispensing gap.

[0015] In some embodiments of this application, the minimum distance between the baffle and the outer wall of the roller is less than the thickness of a single anti-color-crossing sheet.

[0016] The above technical solution has the following advantages or beneficial effects: by ensuring that the minimum distance between the baffle and the outer wall of the roller is less than the thickness of a single anti-color-crossing sheet, only one anti-color-crossing sheet can pass through the dispensing gap at a time. This allows a single anti-color-crossing sheet to pass smoothly through the dispensing gap and fall into the bucket opening and washing chamber, thus achieving automatic dispensing of anti-color-crossing sheets one by one. This avoids multiple anti-color-crossing sheets entering the dispensing gap at the same time, which would cause errors in the number of anti-color-crossing sheets dispensed.

[0017] In some embodiments of this application, the accommodating cavity is provided with a column extending along the height direction, the column being located on one side of the anti-color-crossing sheet; a pressure plate is movably fitted on the column, the pressure plate being able to move up and down along the column; the pressure plate is used to abut against the top surface of the anti-color-crossing sheet located at the top of the accommodating cavity.

[0018] The above-mentioned technical solution has the following advantages or beneficial effects: by pressing the plate against the top surface of the anti-color-crossing sheet located at the top of the receiving cavity, multiple anti-color-crossing sheets can be stably stacked in the receiving cavity. Furthermore, when the roller rolls, the pressing plate can provide downward pressure to the anti-color-crossing sheets, increasing the friction between the roller and the anti-color-crossing sheet located at the bottom of the receiving cavity, thereby enabling the roller to smoothly move the anti-color-crossing sheets.

[0019] In some embodiments of this application, the column extends downward from the top surface of the accommodating cavity, and a spring is sleeved on the column, the spring being positioned above the pressure plate; the top end of the spring abuts against the top surface of the accommodating cavity, and the bottom end of the spring abuts against the pressure plate, so that the pressure plate abuts against the top surface of the anti-color bleeding sheet.

[0020] The above-mentioned technical solution has the following advantages or beneficial effects: The spring's compression force allows the pressure plate to maintain contact with the top surface of the uppermost anti-color-bleeding sheet. As the lower anti-color-bleeding sheets are gradually placed into the washing chamber, the pressure plate can gradually move downwards along the column, cooperating with the spring's elasticity to maintain contact with the top surface of the uppermost anti-color-bleeding sheet, providing downward pressure to the anti-color-bleeding sheet, thereby maintaining stable friction between the roller and the anti-color-bleeding sheet.

[0021] In some embodiments of this application, the bottom end of the column is suspended within the accommodating cavity, and the bottom end of the column is provided with an anti-detachment plate. The pressure plate is disposed above the anti-detachment plate, and the anti-detachment plate is used to prevent the pressure plate from detaching from the bottom end of the column.

[0022] The above-mentioned technical solution has the following advantages or beneficial effects: by setting the anti-detachment plate at the bottom of the column, it can be used to prevent the pressing plate from detaching from the bottom of the column, thereby improving the structural stability of the dispensing device.

[0023] In some embodiments of this application, the top of the housing is provided with a frame, and the clothing inlet is located within the frame; the receiving cavity is located within the frame, and the top surface of the frame is provided with an inlet communicating with the top of the receiving cavity; the anti-color-crossing sheet can be inserted into the receiving cavity through the inlet; the dispensing device includes: a dispensing cover, which is movably disposed on the inlet, and the dispensing cover is used to open and close the inlet.

[0024] The above-mentioned technical solution has the following advantages or beneficial effects: By providing an inlet on the top surface of the enclosure, user convenience can be improved. Users can insert anti-color-crossing sheets into the receiving cavity through the inlet. When the anti-color-crossing sheets in the receiving cavity decrease, they can be replenished through the inlet. The integrity of the top surface of the enclosure can be improved by opening and closing the inlet with the dispensing cover.

[0025] In some embodiments of this application, the dispensing device includes: a drive shaft passing through the center of the roller; the output end of the drive motor is connected to the drive shaft, and the drive motor can drive the roller to rotate through the drive shaft.

[0026] The above technical solution has the following advantages or beneficial effects: by connecting the drive shaft and the roller coaxially, the output end of the drive motor is connected to the drive shaft, and the drive motor can drive the roller to rotate through the drive shaft, thereby driving the color strips to move through the rolling of the roller.

[0047] like Figure 1 As shown, the pulsator washing machine provided in this embodiment of the present invention may include a casing 1. The casing 1 may have a rectangular hollow structure. The casing 1 serves as the outer shell of the pulsator washing machine, and its appearance shape can be designed as needed. The internal space of the casing 1 can provide installation space for other components of the pulsator washing machine.

[0048] Figure 2 yes Figure 1 Internal structural diagram. Figure 3 yes Figure 1 Structural diagram of the middle frame 11.

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, a clothing inlet 10 may be provided on the top side wall of the housing 1. This clothing inlet 10 can connect to the internal space of the housing 1. Clothes can be placed into the interior of the housing 1 through the clothing inlet 10 for washing.

[0050] In some embodiments, a door cover 12 may be provided on the top surface of the housing 1. The door cover 12 can be used to open and close the clothing loading port 10 on the top surface of the housing 1, thereby opening and closing the space inside the housing 1 through the door cover 12.

[0051] In some embodiments, the door cover 12 is rotatably disposed on the top of the housing 1. The rear edge of the door cover 12 is rotatably connected to the top of the housing 1. The rear edge of the door cover 12 is rotatably connected to the rear edge of the clothing inlet 10. Therefore, the front end of the door cover 12 can rotate around its rear end. It should be noted that in some other embodiments, the door cover 12 may also be rotatably connected to the top of the housing 1 via other side edges.

[0052] In some embodiments, the top of the housing 1 may be provided with a frame 11. The frame 11 may be a rectangular frame structure. The clothing inlet 10 may be located at the center of the frame 11. The rear end of the door cover 12 is rotatably disposed on the frame 11. The rear end of the door cover 12 may rotate relative to the frame 11, thereby causing the front end of the door cover 12 to cover or open the clothing inlet 10, realizing the opening and closing of the door cover 12, and thus opening and closing the clothing inlet 10 on the frame 11.

[0053] like Figure 2 As shown, in some embodiments, the pulsator washing machine may include a tub assembly 2. The tub assembly 2 may be disposed inside the casing 1. The tub assembly 2 may be arranged vertically in the up-down direction. A washing chamber 20 may be formed inside the tub assembly 2. The top of the tub assembly 2 is provided with a tub opening 201. The tub opening 201 of the tub assembly 2 can communicate with the interior of the washing chamber 20. The tub opening 201 of the tub assembly 2 is directly opposite to the clothes inlet 10 at the top of the casing 1. The clothes inlet 10 and the tub opening 201 are arranged vertically opposite to each other and communicate with each other, so that the clothes inlet 10 can communicate with the interior of the washing chamber 20. When the door cover 12 is rotated to lift the front end of the door cover 12, the clothes inlet 10 can be opened, and clothes can be placed into the washing chamber 20 inside the tub assembly 2 in sequence through the clothes inlet 10 of the casing 1 and the tub opening 201 at the top of the tub assembly 2 for washing, spin-drying and other operations. When the door cover 12 rotates and the front end of the door cover 12 descends, the clothes loading port 10 can be closed by the door cover 12. The door cover 12 can simultaneously close the clothes loading port 10 and the washing chamber 20.

[0054] In some embodiments, the tub assembly 2 may include an outer tub 21. The outer tub 21 may be disposed inside the housing 1. The top of the outer tub 21 has a tub opening, which may form a tub opening 201 at the top of the tub assembly 2. The outer tub 21 is configured to contain washing water, that is, the internal space of the outer tub 21 can be used to hold washing liquids, such as water, detergent, fabric softener, etc.

[0055] In some embodiments, the tub assembly 2 may include a washing tub 22. The washing tub 22 is disposed inside the outer tub 21. A washing chamber 20 may be formed inside the washing tub 22. The washing chamber 20 within the washing tub 22 is used to hold clothes to be washed. A water passage hole (not shown) may be provided on the peripheral wall of the washing tub 22. The washing chamber 20 can connect the space between the washing tub 22 and the outer tub 21 through the water passage hole. The washing liquid in the outer tub 21 can enter the washing chamber 20 within the washing tub 22 through the water passage hole, that is, the washing liquid in the space between the washing tub 22 and the outer tub 21 can enter the washing chamber 20 within the washing tub 22 through the water passage hole.

[0056] In some embodiments, the washing tub 22 is rotatably disposed inside the outer tub 21. When the washing tub 22 rotates relative to the outer tub 21, the washing tub 22 can drive the clothes to rotate relative to the outer tub 21, thereby realizing the washing function of the clothes in the washing chamber 20 of the washing tub 22 and improving the uniformity of washing and dehydration of the clothes. It should be noted that in other embodiments, the washing chamber 20 can also be used to dry clothes, such as in a washer-dryer combo.

[0057] In some embodiments, the outer tub 21 and the washing tub 22 may be arranged coaxially inside and outside. The top of the washing tub 22 may have an opening that is arranged opposite to the top opening of the outer tub 21. The top opening of the outer tub 21 and the top opening of the washing tub 22 may be combined to form the opening 201 of the tub assembly 2.

[0058] Figure 4 yes Figure 3 A structural diagram from another perspective. Figure 5 yes Figure 3 A top view. Figure 6 yes Figure 5 Sectional view along the AA direction. Figure 7 yes Figure 6 Enlarged structural diagram of region B in the middle.

[0059] like Figure 4 and Figure 7 As shown, in some embodiments, the pulsator washing machine may include a dispensing device 3, which is used to automatically dispense an anti-color-bleeding sheet 4 (also called a color-protecting sheet) into the washing chamber 20. The anti-color-bleeding sheet 4 can quickly absorb the color washed off the clothes, achieving the effect of color protection and preventing color bleeding. The dispensing device 3 is located on the top of the casing 1 and above the tub opening 201. The dispensing device 3 can insert the anti-color-bleeding sheet 4 downward into the washing chamber 20 through the tub opening 201 of the tub assembly 2.

[0060] Figure 8 yes Figure 4 Enlarged structural diagram of region C in the middle.

[0061] like Figure 7 and Figure 8As shown, in some embodiments, the dispensing device 3 may include a receiving cavity 30. The receiving cavity 30 is used to place anti-color-crossing sheets 4, and multiple anti-color-crossing sheets 4 may be stacked sequentially from bottom to top in the receiving cavity 30. The receiving cavity 30 may be located in the area above the bucket opening 201 of the bucket assembly 2, so that the anti-color-crossing sheets 4 inside the receiving cavity 30 can fall downward into the bucket opening 201 and then downward into the washing chamber 20 through the bucket opening 201.

[0062] In some embodiments, the receiving cavity 30 may be located on the outer periphery of the clothing inlet 10, such that the receiving cavity 30 may be located in the area above the opening 201 of the tub assembly 2. The receiving cavity 30 may be arranged close to the clothing inlet 10, and the diameter of the opening 201 of the tub assembly 2 is larger than the diameter of the clothing inlet 10, so that the anti-color-crossing sheet 4 inside the receiving cavity 30 can fall downward into the washing chamber 20 through the area of ​​the opening 201 on the outer periphery of the clothing inlet 10, thereby improving the reliability and convenience of dispensing the anti-color-crossing sheet 4.

[0063] In some embodiments, the dispensing device 3 may include a roller 31. A clearance opening 301 is provided at the bottom of the receiving cavity 30, communicating with the interior of the receiving cavity 30. The roller 31 is rotatably disposed at the clearance opening 301. The top of the roller 31 abuts against the bottom surface of the anti-color-crossing sheet 4 at the bottom of the receiving cavity 30 through the clearance opening 301. When the roller 31 rolls, it generates rolling friction with the bottom surface of the anti-color-crossing sheet 4, causing the lowest anti-color-crossing sheet 4 at the bottom of the receiving cavity 30 to move, fall from the bottom of the receiving cavity 30 into the bucket opening 201, and then fall into the washing chamber 20 through the bucket opening 201.

[0064] like Figure 7 and Figure 8 As shown, in some embodiments, a support rib 302 may be provided on each of the opposite sides of the bottom end of the accommodating cavity 30, and the two support ribs 302 are arranged at intervals and opposite to each other. The two ends of the anti-color-crossing sheet 4 may be supported on a support rib 302 respectively, so that multiple anti-color-crossing sheets 4 can be stacked on the two support ribs 302 in sequence, and the multiple anti-color-crossing sheets 4 can be stably placed in the accommodating cavity 30.

[0065] In some embodiments, a clearance opening 301 is formed between two support ribs 302, allowing the roller 31 to be rotatably arranged in the area between the two support ribs 302. The top of the roller 31 can be positioned upward above the clearance opening 301, thereby abutting against the bottom surface of the anti-color-crossing sheet 4 above the clearance opening 301, that is, against the bottom surface of the lowest anti-color-crossing sheet 4 at the bottom of the receiving cavity 30. The roller 31 can rotate within the clearance opening 301, causing the top of the roller 31 to roll and rub against the bottom surface of the anti-color-crossing sheet 4, driving the anti-color-crossing sheet 4 to move, and then fall downward from one side of the clearance opening 301 into the tub opening 201 and the washing cavity 20.

[0066] In some embodiments, the roller 31 may be arranged to extend along its axis to increase the length of the roller 31, thereby increasing the contact area between the roller 31 and the anti-color-bleeding sheet 4 and increasing the friction between the roller 31 and the anti-color-bleeding sheet 4.

[0067] like Figure 7 and Figure 8 As shown, in some embodiments, the dispensing device 3 may include baffles 32, which are spaced apart on one side of the roller 31. The upper end of the baffle 32 extends into the receiving cavity 30 and is located on one side of the anti-color-crossing sheet 4. A dispensing gap 33 is provided between the baffle 32 and the roller 31, and the bottom end of the dispensing gap 33 faces and communicates with the bucket opening 201. When the roller 31 rolls, the top of the roller 31 can rotate toward the baffle 32, and the roller 31 can roll and rub against the bottom surface of the anti-color-crossing sheet 4 located at the bottom of the receiving cavity 30. Through the action of rolling friction, the anti-color-crossing sheet 4 located at the bottom of the receiving cavity 30 can move toward the baffle 32, so that the anti-color-crossing sheet 4 abuts against the baffle 32 and enters the dispensing gap 33, and then falls down along the dispensing gap 33 into the bucket opening 201 and the washing cavity 20, realizing the automatic dispensing function of the anti-color-crossing sheet 4. The rolling friction between the roller 31 and the anti-color-crossing sheet 4 acts as a thrust, driving the anti-color-crossing sheet 4 to move. Combined with the blocking effect of the baffle 32, the bottom anti-color-crossing sheet 4 is separated from the anti-color-crossing sheets 4 stacked on top of it, thereby realizing the sequential delivery of the anti-color-crossing sheets 4 one by one.

[0068] like Figure 7 and Figure 8 As shown, in some embodiments, the dispensing device 3 may include a drive motor 34, which is connected to the roller 31. The drive motor 34 drives the roller 31 to rotate. When the drive motor 34 drives the roller 31 to rotate, the roller 31 can roll and rub against the bottom surface of the anti-color-crossing sheet 4 located at the bottom of the receiving cavity 30, so as to drive the anti-color-crossing sheet 4 to move towards the baffle 32, so that the anti-color-crossing sheet 4 abuts against the baffle 32 and enters the dispensing gap 33, and then falls down along the dispensing gap 33 into the bucket opening 201 and the washing cavity 20, thereby realizing the automatic dispensing function of the anti-color-crossing sheet 4.

[0069] Compared to the manual dispensing of the anti-color-bleeding sheets 4, this embodiment utilizes the cooperative structure of the drive motor 34, roller 31, and baffle 32 to achieve automatic sequential dispensing of the anti-color-bleeding sheets 4, improving ease of use. During the washing process, the total weight of the clothes can be detected by a detection device. Based on the total weight, a signal is sent to the drive motor 34 to rotate for a preset time, thereby automatically dispensing a preset number of anti-color-bleeding sheets 4, achieving automated dispensing and washing function. The number of anti-color-bleeding sheets 4 has a certain proportional relationship with the total weight of the clothes, and this ratio can be adjusted.

[0070] like Figure 7 and Figure 8 As shown, in some embodiments, the dispensing device 3 may include a drive shaft 35, which passes through the axis of the roller 31. The drive shaft 35 is coaxially arranged with the roller 31, and the drive shaft 35 may extend along the axis of the roller 31. The output end of the drive motor 34 is connected to the drive shaft 35, and the drive motor 34 can drive the roller 31 to rotate through the drive shaft 35, thereby causing the anti-color-crossing sheet 4 to move by rolling the roller 31.

[0071] like Figure 7 and Figure 8 As shown, in some embodiments, the receiving cavity 30 can be located within the frame 11, and the receiving cavity 30 can be located on the outer periphery of the clothing inlet 10. Baffles 32 can be spaced apart on the side of the roller 31 near the clothing inlet 10, and the upper end of the baffle 32 can be arranged on the side of the anti-color-crossing sheet 4 near the clothing inlet 10. The lower end of the baffle 32 is located below the clearance opening 301 and extends towards the side near the clothing inlet 10. When the roller 31 rolls, the roller 31 can drive the anti-color-crossing sheet 4 to move towards the side near the clothing inlet 10, causing the anti-color-crossing sheet 4 to move towards the baffle 32, thereby causing the anti-color-crossing sheet 4 to abut against the baffle 32, and enter the feeding gap 33 from the side of the clearance opening 301 near the clothing inlet 10, and then fall downwards into the tub opening 201 and the washing chamber 20. In addition, the lower end of the baffle 32 extends toward the side close to the clothing inlet 10, so that after the anti-color-crossing sheet 4 abuts against the baffle 32, the end of the anti-color-crossing sheet 4 can smoothly enter the inlet gap 33 along the surface of the baffle 32.

[0072] like Figure 7 and Figure 8 As shown, in some embodiments, a first fixing plate 111 and a second fixing plate 112 are provided inside the frame 11. The first fixing plate 111 and the second fixing plate 112 can be arranged to extend downward from the inner wall of the frame 11, respectively. The first fixing plate 111 and the second fixing plate 112 are respectively located on opposite sides of the accommodating cavity 30. The two ends of the drive shaft 35 can be rotatably connected to the first fixing plate 111 and the second fixing plate 112, respectively. The drive motor 34 is provided on the first fixing plate 111. The drive motor 34 can drive the drive shaft 35 to rotate, and through the drive shaft 35, drive the roller 31 to rotate between the first fixing plate 111 and the second fixing plate 112, so that the roller 31 rotates within the clearance opening 301.

[0073] It should be noted that in some other embodiments, the two ends of the drive shaft 35 may also be rotatably connected to the opposite side walls of the accommodating cavity 30. The drive motor 34 may also be disposed on the outer side wall of the accommodating cavity 30.

[0075] like Figure 9 and Figure 10 As shown, in some embodiments, the lower end of the baffle 32 extends in an arc shape toward the side near the clothing inlet 10. In this way, the surface of the baffle 32 facing the roller 31 can form an arc-shaped surface. When the roller 31 moves the anti-color-bleeding sheet 4, and the anti-color-bleeding sheet 4 comes into contact with the baffle 32, the end of the anti-color-bleeding sheet 4 can smoothly enter the inlet gap 33 along the arc-shaped surface of the baffle 32, and then fall down along the inlet gap 33 into the tub opening 201 and the washing chamber 20.

[0076] In some embodiments, the minimum distance between the baffle 32 and the outer wall of the roller 31 is less than the thickness of a single anti-color-crossing sheet 4, that is, the width at the narrowest point of the dispensing gap 33 is less than the thickness of a single anti-color-crossing sheet 4. Thus, when the anti-color-crossing sheet 4 enters the dispensing gap 33, it can be held between the baffle 32 and the roller 31. Utilizing the friction of the roller 31 on the anti-color-crossing sheet 4, and considering that the minimum distance between the baffle 32 and the outer wall of the roller 31 is less than the thickness of a single anti-color-crossing sheet 4, the dispensing gap 33 can only accommodate one anti-color-crossing sheet 4 at a time. This allows a single anti-color-crossing sheet 4 to pass smoothly through the dispensing gap 33 and fall into the bucket opening 201 and the washing chamber 20, achieving automatic sequential dispensing of the anti-color-crossing sheets 4. This avoids errors in the number of anti-color-crossing sheets 4 dispensed if multiple sheets 4 enter the dispensing gap 33 simultaneously.

[0077] like Figure 9 and Figure 10 As shown, in some embodiments, the ends of the support ribs 302 can be spaced apart from the baffles 32, and an interval 303 can be formed between the ends of the support ribs 302 near the baffles 32 and the baffles 32. The interval 303 is connected to the dispensing gap 33. When the roller 31 moves the anti-color-crossing sheet 4, causing the anti-color-crossing sheet 4 to abut against the baffles 32, the end of the anti-color-crossing sheet 4 can enter the dispensing gap 33 through the interval 303, allowing the anti-color-crossing sheet 4 to pass smoothly through the dispensing gap 33 and fall downward into the bucket opening 201 and the washing chamber 20.

[0078] Figure 11 yes Figure 3 A magnified view of the local structure. Figure 12 yes Figure 11 Structure diagram in another state.

[0079] like Figure 7 and Figure 12As shown, in some embodiments, a column 36 extending along the height direction may be provided inside the accommodating cavity 30, with the column 36 located on one side of the anti-color-crossing sheet 4. A pressure plate 37 is movably fitted onto the column 36, and the pressure plate 37 can move up and down along the column 36. The pressure plate 37 is used to abut against the top surface of the anti-color-crossing sheet 4 located at the top of the accommodating cavity 30, thereby allowing multiple anti-color-crossing sheets 4 to be stably stacked inside the accommodating cavity 30. Furthermore, when the roller 31 rolls, the pressure plate 37 can provide downward pressure to the anti-color-crossing sheet 4, increasing the friction between the roller 31 and the anti-color-crossing sheet 4 located at the bottom of the accommodating cavity 30, thereby enabling the roller 31 to smoothly move the anti-color-crossing sheet 4.

[0080] In some embodiments, the column 36 may be located on the side of the anti-color-crossing sheet 4 away from the baffle 32, so that multiple anti-color-crossing sheets 4 can be stably placed in the area between the baffle 32 and the column 36.

[0081] It should be noted that in some other embodiments, the column 36 may also be located on one side of the anti-color-crossing sheet 4 in other directions.

[0082] like Figure 7 As shown, in some embodiments, the column 36 extends downward from the top surface of the receiving cavity 30. A spring 38 may be fitted on the column 36, positioned above the pressure plate 37. The top end of the spring 38 abuts against the top surface of the receiving cavity 30, and the bottom end of the spring 38 abuts against the pressure plate 37, so that the pressure plate 37 abuts against the top surface of the anti-color-bleeding sheet 4. Through the squeezing force of the spring 38, the pressure plate 37 can maintain contact with the top surface of the uppermost anti-color-bleeding sheet 4. As the lower anti-color-bleeding sheet 4 is gradually inserted into the washing chamber 20, the pressure plate 37 can gradually move downward along the column 36, cooperating with the elastic force of the spring 38 to maintain contact with the top surface of the uppermost anti-color-bleeding sheet 4, providing downward pressure to the anti-color-bleeding sheet 4, thereby maintaining a stable frictional force between the roller 31 and the anti-color-bleeding sheet 4.

[0083] like Figure 7 As shown, in some embodiments, the bottom end of the column 36 is suspended within the receiving cavity 30, and an anti-detachment plate 361 may be provided at the bottom end of the column 36. A pressure plate 37 is disposed above the anti-detachment plate 361, which prevents the pressure plate 37 from detaching from the bottom end of the column 36. By providing the anti-detachment plate 361 at the bottom end of the column 36, the pressure plate 37 can be prevented from detaching from the bottom end of the column 36, thereby improving the structural stability of the dispensing device 3.

[0084] In some embodiments, the anti-detachment piece 361 may be annular. The annular anti-detachment piece 361 can be detachably fitted onto the bottom end of the column 36. During installation, the spring 38 and the pressure plate 37 can be sequentially fitted onto the column 36, and then the anti-detachment piece 361 can be fitted onto the bottom end of the column 36 to prevent the spring 38 and the pressure plate 37 from detaching from the bottom end of the column 36.

[0085] It should be noted that in some other embodiments, the column 36 may also be arranged to extend upward from the bottom surface of the receiving cavity 30.

[0086] like Figure 8 and Figure 12 As shown, in some embodiments, multiple sets of columns 36 may be provided, with multiple columns 36 arranged at intervals in the accommodating cavity 30 and located on one side of the anti-color-crossing sheet 4.

[0087] like Figure 3 , Figure 7 and Figure 12 As shown, in some embodiments, the receiving cavity 30 is located inside the frame 11, and the top surface of the frame 11 may have an inlet 113 communicating with the top of the receiving cavity 30. The anti-color-crossing sheet 4 can be inserted into the receiving cavity 30 through the inlet 113. By providing the inlet 113 on the top surface of the frame 11, the convenience of use for the user can be improved. The user can insert the anti-color-crossing sheet 4 into the receiving cavity 30 through the inlet 113. When the anti-color-crossing sheet 4 in the receiving cavity 30 decreases, it can be replenished into the receiving cavity 30 through the inlet 113.

[0088] like Figure 11 and Figure 12 As shown, in some embodiments, the dispensing device 3 may include a dispensing cover 39, which is movably disposed over the dispensing inlet 113. The dispensing cover 39 is used to open and close the dispensing inlet 113 to improve the integrity of the top surface of the enclosure 11.

[0089] In some embodiments, the dispensing cover 39 may be rotatably connected to the dispensing inlet 113. In other embodiments, the dispensing cover 39 may also be detachably disposed on the dispensing inlet 113.

[0090] Figure 13 yes Figure 12 Structural diagram of the middle-mounted cover 39. Figure 14 yes Figure 13 A decomposed structure diagram.

[0091] like Figure 13 and Figure 14As shown, in some embodiments, a lock body 391 may be provided on the dispensing cover 39, and the lock body 391 is rotatably disposed on the dispensing cover 39. When the dispensing cover 39 closes the dispensing inlet 113, the lock body 391 can rotate, causing the lock body 391 to engage or disengage with the side edge of the dispensing inlet 113, thereby locking or unlocking the dispensing cover 39. Specifically, when the lock body 391 engages with the side edge of the dispensing inlet 113, the lock body 391 can lock the dispensing cover 39, preventing the dispensing cover 39 from being opened. When the lock body 391 disengages from the side edge of the dispensing inlet 113, the lock body 391 can unlock the dispensing cover 39, allowing the user to open the dispensing cover 39.

[0092] In some embodiments, the lock body 391 may include a rotating pin 3911, which is rotatably connected to the dispensing cover 39. The top end of the rotating pin 3911 protrudes from the top surface of the dispensing cover 39. The user can control the rotation of the lock body 391 on the dispensing cover 39 by controlling the exposed portion of the top end of the rotating pin 3911.

[0093] In some embodiments, the lock body 391 may include a lock plate 3912, which is eccentrically connected to the bottom end of the rotating column 3911. When the dispensing cover 39 closes the inlet 113, the lock plate 3912 is located inside the receiving cavity 30. The rotating column 3911 can drive the lock plate 3912 to rotate synchronously, so that the lock plate 3912 can engage or disengage from the side edge of the inlet 113, thereby realizing the locking and unlocking functions of the dispensing cover 39.

[0094] In some embodiments, the dispensing cover 39 is provided with a shaft hole 392. A limiting ring 3913 is provided on the peripheral wall of the rotating column 3911. The rotating column 3911 is rotatably connected to the shaft hole 392, and the limiting ring 3913 is provided on the top surface of the dispensing cover 39 to limit the rotating column 3911 to rotate within the shaft hole 392 and prevent the rotating column 3911 from detaching from the dispensing cover 39.
