[0019] In addition, the embodiments of the present disclosure and the technical features in the embodiments can be combined with each other without contradiction. The detailed description in the specific embodiments should be understood as an explanation of the gist of the present disclosure and should not be regarded as an undue limitation to the present disclosure.

[0020] In the embodiments of the present disclosure, the orientations or positional relationships of "upper", "lower", "inner", "outer", "front", "rear", "left", and "right" are based on the orientations or positional relationships shown in FIGS. 3, 4, and 7. It is only for facilitating the description of the present disclosure and simplifying the description, and does not indicate or imply that the specified device or element must have a specific orientation and must be configured and operated in a specific orientation. Therefore, it should not be understood as a limitation to the present disclosure. Hereinafter, the present disclosure will be described in more detail with reference to the drawings and specific embodiments.

[0021] Referring to FIGS. 1 to 4, an embodiment of the present disclosure provides a clothing treatment device, and the clothing treatment device includes an outer cylinder 1, an inner cylinder having a clothing chamber, a door seal 2, a detergent device 3, a circulation pump 4, and a liquid discharge flow path 5. The clothing chamber is used for putting clothes.

[0022] One axial side of the outer cylinder 1 has an opening, and the inner cylinder is rotatably provided in the outer cylinder 1. By rotating the inner cylinder to move the movement of clothes, detergent and / or aqueous liquid, the clothes are processed.

[0023] The door seal 2 surrounds the opening of the outer cylinder 1. The door seal 2 is formed with a liquid supply port 2a and a clothing inlet 2b communicating with the clothing chamber. The door seal 2 has a substantially annular structure. The space surrounded by the door seal 2 is the clothing inlet 2b. The door seal 2 can prevent the liquid in the inner cylinder and the outer cylinder 1 from flowing out to the outside. The clothing inlet 2b communicates with the clothing chamber. The clothing chamber is open toward the opening of the outer cylinder 1. The user can put clothes into or take clothes out of the clothing chamber through the clothing inlet 2b.

[0024] Referring to FIGS. 3, 4, 5 and 8, the detergent device 3 includes a detergent box 31 and a filter 32. A mixing chamber 31a is formed in the detergent box 31. The filter 32 is accommodated in the mixing chamber 31a. The filter 32 is formed with a water inlet 32a and a water outlet 32b. The water outlet 32b communicates with the mixing chamber 31a. The circulation pump 4 sends the liquid in the outer cylinder 1 to the water inlet 32a. The liquid discharge channel 5 communicates the mixing chamber 31a and the liquid supply port 2a. Specifically, the liquid supply port 2a communicates with the clothing chamber.

[0025] According to the clothing treatment device provided in the embodiment of the present disclosure, the liquid carrying lint in the clothing chamber enters the filter 32 through the water inlet 32a. The filtered water filtered by the filter 32 enters the mixing chamber 31a through the water outlet 32b. The lint remains on the filter 32. The liquid discharge channel 5 directly discharges the filtered water in the mixing chamber 31a from the liquid supply port 2a into the clothing chamber. On the one hand, by accommodating the filter 32 in the mixing chamber 31a, not only can a mounting position be provided for the filter 32, but also it is easy to send the filtered water from the water outlet 32b into the mixing chamber 31a. Therefore, drainage can be performed using the liquid discharge channel 5, and there is no need to separately provide a pipeline for discharging to the clothing chamber for the water outlet 32b, reducing the piping, simplifying the structure, and reducing the cost. On the other hand, the filtered water can directly enter the clothing chamber through the liquid supply port 2a and does not need to enter the inner cylinder after passing through the outer cylinder 1. Therefore, the liquid inflow speed can be improved, and the filtered water can form a continuous water flow even at the door seal 2. The user can intuitively feel the flow of the filtered water, improving the appearance.

[0026] In one embodiment, referring to FIGS. 1 and 3, the liquid supply port 2a penetrates the peripheral side wall of the door seal 2 along the radial direction of the outer cylinder 1. In this way, the liquid supply port 2a communicates with the clothing inlet 2b, and the liquid from the liquid supply port 2a enters the clothing chamber through the clothing inlet 2b.

[0027] In one embodiment, a drain hole is formed in the inner cylinder, and the outer cylinder 1 is used to store water. In this way, the liquid in the clothing chamber can flow between the inner cylinder and the outer cylinder 1.

[0028] Exemplarily, in one embodiment, the clothing processing device includes a door body and a box body, and both the inner cylinder and the outer cylinder 1 are provided in the box body. The box body has an access opening that is open toward the opening of the outer cylinder 1, and the door body is used to open and close the access opening. The door seal 2 is used to seal the gap between the outer cylinder 1 and the access opening. When the door body closes the access opening, the door body seals and abuts against the door seal 2. When the door body opens the access opening, the user can take in and out clothing through the access opening and the clothing inlet 2b.

[0029] The door seal 2 can be manufactured from a flexible material. The flexible material refers to a material that can maintain the form of the door seal 2 and further has a certain elastic deformation ability. Exemplarily, the material of the door seal 2 includes, but is not limited to, rubber or silicon.

[0030] The type of the clothing processing device is not limited. Exemplarily, the clothing processing device includes, but is not limited to, a washing machine or a washing and drying machine.

[0031] The axis of the inner cylinder can be provided along the horizontal direction. For example, the clothing processing device is a drum-type clothing processing device. The axis of the inner cylinder can also be provided obliquely.

[0032] The position of the detergent box 31 is not limited. Exemplarily, in one embodiment, referring to FIG. 3, the detergent box 31 may be located above the outer cylinder 1. In this way, the aqueous liquid in the mixing chamber 31a flows downward, making it easier to enter the clothing chamber.

[0033] In some embodiments, referring to FIGS. 4 and 5, the detergent box 31 includes a box lid 311 and a box body 312. In the box body 312, a mixing chamber 31a and an upper opening communicating with the mixing chamber 31a are formed. The box lid 311 covers the upper opening of the box body 312.

[0034] The box lid 311 and the box body 312 can be connected by means such as snaps, screws, and / or bolts.

[0035] In one embodiment, referring to FIG. 4, the detergent device 3 includes a dispensing box 36 that is slidably provided in the detergent box 31, and the filter 32 is provided in the dispensing box 36. Referring to FIG. 4, the dispensing box 36 is in a state of being pulled out from the detergent box 31. During normal use of the clothing treatment device, the dispensing box 36 is pushed into the detergent box 31.

[0036] Exemplarily, the dispensing box 36 has a plurality of receiving grooves. One of the receiving grooves is used to place the filter 32, and the other receiving grooves are used to place the detergent bottle 37 and / or the input box. The detergent bottle 37 may be used to contain detergent, and both the detergent bottle 37 and the input box may be used to supply detergent to the mixing chamber 31a.

[0037] Note that the plurality includes two or more numbers.

[0038] The types of detergents include, but are not limited to, fluids such as detergents, fabric softeners, disinfectants, or perfumes.

[0039] In one embodiment, referring to FIGS. 5 and 8, the laundry treating apparatus includes a feed pump 9 which is used to suck the detergent in the detergent bottle 37 and send it into the mixing chamber 31a. The feed pump 9 can send the detergent quantitatively, and the amount of detergent input becomes more accurate. The detergent in the mixing chamber 31a enters the laundry chamber through the liquid discharge passage 5 and via the door seal 2, so that the detergent directly contacts the laundry.

[0040] Exemplarily, a plurality of receiving grooves may be arranged side by side along the left - right direction. In this way, it becomes easier to arrange the filter 32, the detergent bottle 37 and / or the feed box along the left - right direction.

[0041] Note that the front - rear direction, the left - right direction, and the up - down direction are perpendicular to each other and together constitute a three - dimensional rectangular coordinate system.

[0042] Exemplarily, in one embodiment, a drawer opening may be provided on the front side of the cabinet, and the distribution box 36 can be pulled out or pushed into the detergent box 31 through the drawer opening. In this way, the user can pull out the distribution box 36 from the front of the cabinet, making it easier to take in and out consumables such as the filter 32 and the detergent bottle 37.

[0043] In some embodiments, the detergent bottle 37 may be a disposable device. After the detergent in the detergent bottle 37 is used up, the user can remove the detergent bottle 37 and replace it with a new one, saving the trouble of pouring detergent into the feed box. In some other embodiments, the user can inject detergent into the detergent bottle 37, and the detergent bottle 37 can be reused, which is energy - saving and environmentally friendly.

[0044] In some embodiments, referring to FIGS. 3 to 8, an overflow chamber 31b communicating with the mixing chamber 31a is formed in the detergent box 31. An overflow port 31b' is formed in the overflow chamber 31b, and the overflow port 31b' communicates with the outer cylinder 1. When the liquid level in the mixing chamber 31a is higher than a predetermined height, the liquid in the mixing chamber 31a enters the overflow chamber 31b and is discharged through the overflow port 31b'. Exemplarily, the liquid in the mixing chamber 31a enters the liquid discharge flow path 5. When the liquid inflow rate in the mixing chamber 31a is greater than the liquid discharge rate, the liquid level in the mixing chamber 31a gradually rises until it is higher than the predetermined height. After the liquid in the mixing chamber 31a enters the overflow chamber 31b, it is discharged to the outer cylinder 1 through the overflow port 31b'. In this way, after the liquid in the overflow chamber 31b is discharged to the outer cylinder 1 through the overflow port 31b', it can enter the clothing chamber through the drain hole of the inner cylinder. Therefore, the overflow port 31b' plays a role in assisting liquid discharge and can avoid the situation where the liquid in the mixing chamber 31a is not discharged in a timely manner.

[0045] In one embodiment, referring to FIG. 3, a communication port is formed in the outer cylinder 1, and the clothing treatment device includes an overflow flow path 10 that communicates the overflow port 31b' and the communication port. For example, the overflow flow path 10 may have a pipe structure. In this way, the liquid in the overflow chamber 31b is discharged to the outer cylinder 1 through the overflow flow path 10.

[0046] In one embodiment, referring to FIGS. 2 and 3, the clothing treatment device includes a liquid supply flow path 6, and the detergent device 3 includes a venturi joint 33 provided below the detergent box 31. Exemplarily, referring to FIG. 7, the venturi joint 33 is provided below the box body 312.

[0047] Referring to FIGS. 2, 3, 6 and 7, the Venturi joint 33 has a first port 33a, a second port 33b, and a negative pressure port 33c. The first port 33a communicates with the liquid supply channel 6, the second port 33b communicates with the liquid discharge channel 5, and the negative pressure port 33c communicates with the mixing chamber 31a. Specifically, the liquid supply channel 6 is used to provide cleaning water such as tap water. For example, the water supply channel 6 is connected to a tap water pipe via a water inlet valve.

[0048] When the liquid supply channel 6 supplies water to the Venturi joint 33 through the first port 33a, a negative pressure is generated at the negative pressure port 33c by the water flow. The liquid in the mixing chamber 31a is sucked into the Venturi joint. The water flow and the liquid merge in the liquid discharge channel 5 and enter the liquid discharge channel 5, flowing to the liquid supply port 2a of the door seal 2.

[0049] Here, on the one hand, by providing a pipe connection position to the liquid discharge channel 5 etc. by the Venturi joint 33, the attachment of the liquid discharge channel 5 becomes easy. On the other hand, by generating a Venturi effect using the Venturi joint 33, a negative pressure can be generated at the negative pressure port 33c, accelerating the liquid discharge speed in the mixing chamber 31a, so that as much liquid as possible in the mixing chamber 31a is discharged from the liquid discharge channel 5. For example, the water mixed with the detergent in the mixing chamber 31a can enter the clothing chamber from the liquid supply port 2a of the door seal 2 as much as possible, the detergent can directly enter the clothing chamber and contact the clothes, and the utilization rate of the detergent can be improved.

[0050] Understandably, both the liquid discharge channel 5 and the liquid supply channel 6 may have a pipe structure.

[0051] In some embodiments, referring to FIG. 3, the clothing treatment device includes a water supply branch channel 110, and the detergent device 3 includes a water supply joint 38 provided in the detergent box 31 and communicating with the mixing chamber 31a. Exemplarily, the water supply joint 38 is provided on the upper part of the box lid 311.

[0052] The water supply branch 110 communicates the liquid supply channel 6 with the water supply joint 38. When water enters the liquid supply channel 6, a part of the aqueous liquid in the liquid supply channel 6 can enter the mixing chamber 31a through the water supply branch 110 and the water supply joint 38 to flow the detergent, and a part of the water flow in the liquid supply channel 6 enters the Venturi joint 33. Due to the negative pressure generated at the negative pressure port 33c, the detergent mixture in the mixing chamber 31a merges at the Venturi joint 33 and enters the Venturi joint 33. Then, both enter the liquid supply port 2a through the liquid discharge channel 5 together.

[0053] In one embodiment, referring to FIGS. 6 and 7, the Venturi joint 33 includes an insertion pipe 331 and an outer pipe 332 located below the detergent box 31. The insertion pipe 331 includes a water inlet part 3311 and a pressure reduction part 3312. The area of the minimum cross-sectional area of the water inlet part 3311 is larger than the cross-sectional area of any position of the pressure reduction part 3312. A first port 33a is formed in the water inlet part 3311. The pressure reduction part 3312 is connected to the first end of the outer pipe 332 and inserted into the inside of the outer pipe 332. A second port 33b is formed at the second end of the outer pipe 332. A negative pressure port 33c is formed on the circumferential side wall of the outer pipe 332. That is, the water inlet part 3311 is located outside the outer pipe 332, the pressure reduction part 3312 is located inside the outer pipe 332, and communicates with the space inside the outer pipe 332. The water flow from the first port 33a flows to the second port 33b after passing through the pressure reduction part 3312. Since the area of the minimum cross-sectional area of the water inlet part 3311 is larger than the cross-sectional area of any position of the pressure reduction part 3312, the flow velocity of the water flow passing through the pressure reduction part 3312 is larger than the flow velocity of the water flow passing through the water inlet part 3311, and the water pressure of the water flow in the pressure reduction part 3312 is smaller than the water pressure in the water inlet part 3311. The cross-sectional area of the outer pipe 332 is larger than the cross-sectional area of the pressure reduction part 3312. The flow velocity of the water flow in the pressure reduction part 3312 is larger than the flow velocity of the second port 33b and the water pressure is smaller. Since the water pressure around the outlet of the pressure reduction part 3312 is small, negative pressure is generated at the negative pressure port 33c, and the liquid in the mixing chamber 31a is driven to flow into the outer pipe 332 through the negative pressure port 33c.

[0054] In one embodiment, referring to FIG. 7, the water inlet portion 3311 includes an equal-diameter portion 33111 and a tapered portion 33112. The cross-sectional area of the flow-through section at any position of the equal-diameter portion 33111 is equal. The tapered portion 33112 connects the equal-diameter portion 33111 and the pressure-reducing portion 3312, and the cross-sectional area of the flow-through section of the tapered portion 33112 gradually decreases from the equal-diameter portion 33111 toward the pressure-reducing portion 3312. Understandably, the cross-sectional area of the flow-through section of the equal-diameter portion 33111 and the cross-sectional area of the flow-through section of the tapered portion 33112 are both larger than the cross-sectional area of the flow-through section of the pressure-reducing portion 3312. The water flow flows relatively gently in the equal-diameter portion 33111, and by the equal-diameter portion 33111 playing a rectifying role, the water flow gently enters the tapered portion 33112. The water flow gradually increases in velocity and gradually decreases in water pressure in the tapered portion 33112. The water pressure exhibits a continuous change trend, and the turbulent flow of the water flow can be reduced.

[0055] In one embodiment, referring to FIG. 7, the cross-sectional area of the flow-through section at any position of the pressure-reducing portion 3312 is equal. In this way, the water flow flows relatively gently in the pressure-reducing portion 3312, reducing turbulent flow and pressure loss.

[0056] In one embodiment, referring to FIGS. 6 and 7, both the insertion pipe 331 and the outer pipe 332 extend in the front-rear direction. The detergent box 31 is located above the outer cylinder 1, the door seal 2 is located on the front side of the outer cylinder 1, the water inlet valve is located on the rear side of the outer cylinder 1, and both the insertion pipe 331 and the outer pipe 332 extend in the front-rear direction, facilitating the piping of the liquid supply flow path 6 and the liquid discharge flow path 5.

[0057] Exemplarily, in one embodiment, referring to FIG. 7, the insertion pipe 331 and the outer pipe 332 are coaxially arranged. In this way, the flow of the water flow in the insertion pipe 331 and the outer pipe 332 becomes smoother, and some of the resistance is reduced.

[0058] In one embodiment, referring to FIG. 7, the dimension of the outer tube 332 of the decompression section 3312 along the axial direction is larger than the dimension of the outer tube 332 of the negative pressure port 33c along the axial direction. That is, along the flow direction of the water flow in the outer tube 332, the negative pressure port 33c is located upstream of the outlet of the decompression section 3312. Thereby, negative pressure can be effectively formed at the negative pressure port 33c.

[0059] In one embodiment, referring to FIGS. 2 and 5, the detergent device 3 includes a spare joint 34 provided in the detergent box 31, the clothing treatment device includes an incoming water flow path 7 and a circulating water branch path 8, the incoming water flow path 7 communicates the outlet of the circulation pump 4 with the water inlet 32a, and the circulating water branch path 8 communicates the incoming water flow path 7 with the spare joint 34. When the filter 32 is clogged, the back pressure at the outlet of the incoming water flow path 7 rises, and the circulating water is forced to flow into the circulating water branch path 8 and is discharged from the spare joint 34. Therefore, the spare joint 34 and the circulating water branch path 8 play a role in safety prevention, and when the filter 32 becomes clogged, the circulating water in the incoming water flow path 7 can be discharged in a timely manner, so that the probability of failures such as pipe rupture due to a sudden increase in water pressure and damage to the circulation pump 4 can be reduced.

[0060] Note that the circulating water from the spare joint 34 may be led to any appropriate position. For example, in some embodiments, the circulating water from the spare joint 34 is led back to the clothing chamber via a pipeline.

[0061] Understandably, the incoming water flow path 7 may have a pipe structure.

[0062] In one embodiment, referring to FIGS. 2 and 5, the spare joint 34 communicates with the mixing chamber 31a. In this way, there is no need to provide an additional pipeline to discharge the circulating water from the spare joint 34, and by using the liquid discharge flow path 5 to guide the circulating water back into the clothing chamber, the structure can be simplified and the piping can be reduced.

[0063] In one embodiment, referring to FIGS. 2, 5, and 8, the detergent device 3 includes a connecting pipe 35 provided in the detergent box 31. The connecting pipe 35 communicates the water inlet 32a with the water inlet channel 7. The highest position of the spare joint 34 is higher than the highest position of the connecting pipe 35. The resistance of the spare joint 34 is greater than that of the connecting pipe 35. Since the resistance of the circulating water flowing from the water inlet channel 7 to the filter 32 via the connecting pipe 35 is smaller than the resistance of flowing to the spare joint 34, when the filter 32 is being used normally without clogging, the circulating water preferentially flows to the filter 32 via the connecting pipe 35.

[0064] In one embodiment, referring to FIG. 5, the spare joint 34 is located on the upper surface of the detergent box 31. In this way, the height of the spare joint 34 is ensured to be high.

[0065] In one embodiment, referring to FIGS. 5 and 8, the connecting pipe 35 is formed by drilling through the peripheral wall of the detergent box 31. For example, the spare joint 34 is formed on the box lid 311, and the connecting pipe 35 is formed by drilling through the rear side wall of the box body 312. In this way, it is ensured that the highest position of the connecting pipe 35 is lower than the height of the spare joint 34, and there is a height difference between the spare joint 34 and the connecting pipe 35. Due to this height difference, the corresponding back pressure of the discharged water is generated.

[0066] In one embodiment, referring to FIGS. 1 to 4 and FIG. 8, the laundry treatment apparatus includes an incoming water flow path 7, and the detergent device 3 includes a connecting pipe 35 that penetrates the rear side wall of the detergent box 31. The incoming water flow path 7 communicates the outlet of the circulation pump 4 with the connecting pipe 35. The connecting pipe 35 is communicably inserted into and removed from the water inlet 32a. A partial position of a part of the incoming water flow path 7 is located below the detergent box 31. On the one hand, it is easy for the user to take in and out the filter 32 from the front. The filter 32 is pushed into the detergent box 31 together with the distribution box 36, and the water inlet 32a is inserted and communicated with the connecting pipe 35. The filter 32 is pulled out from the detergent box 31 together with the distribution box 36, and the water inlet 32a is pulled out from the connecting pipe 35 so as to be separated from the connecting pipe 35. Therefore, the user can quickly take out the filter 32, and the assembly is simple and the operation is easy. On the other hand, since the installation space inside the box is limited, and the position where the circulation pump 4 of the conventional laundry treatment apparatus is provided is close to the front side of the outer cylinder 1, the incoming water flow path 7 may need to bypass the detergent box 31 from the front and be connected to the connecting pipe 35. Since a partial position of a part of the incoming water flow path 7 is located below the detergent box 31, not only is there good interchangeability with the circulation pump 4 of the conventional laundry treatment apparatus, but also the design cost can be reduced without changing the position of the circulation pump 4. By arranging the incoming water flow path 7 using the space below the washing box, the piping can be facilitated and the layout can be made beautiful.

[0067] In one embodiment, a concave groove is formed on the bottom surface of the detergent box 31, and a partial position of a part of the incoming water flow path 7 located below the detergent box 31 is accommodated in the concave groove. In this way, it is possible to avoid an increase in the distance between the detergent box 31 and the outer cylinder 1 due to a partial position of a part of the incoming water flow path 7 located below the detergent box 31, and it is also possible to limit the movement of a partial position of a part of the incoming water flow path 7 located below the detergent box 31 to a certain extent.

[0068] In one embodiment, referring to FIGS. 8 to 11, the filter 32 includes a housing 321 and a filter element 322. A yarn waste chamber 321a is formed in the housing 321. The water inlet 32a communicates with the yarn waste chamber 321a. The filter element 322 is located within the yarn waste chamber 321a. Drain holes 322a, a filtration chamber 322b, and filtration holes are formed in the filter element 322. Both the filtration holes and the drain holes 322a communicate with the filtration chamber 322b. The drain holes 322a are aligned and communicate with the water outlet 32b. The liquid from the water inlet 32a is filtered by the filter element 322 to form filtered water. The filtered water enters the filtration chamber 322b through the filtration holes, and then enters the water outlet 32b through the drain holes 322a. On the other hand, the yarn waste is blocked by the filter element 322 and remains in the yarn waste chamber 321a. In this way, the purpose of filtering the yarn waste by the filtration holes can be achieved.

[0069] In one embodiment, referring to FIGS. 8 and 9, both the water inlet 32a and the water outlet 32b are formed on the back side of the housing 321. In this way, the insertion and connection between the water inlet 32a and the connecting pipe 35 are facilitated, and the interference of the distribution box 36 with the water discharged from the water outlet 32b can be avoided.

[0070] In one embodiment, referring to FIG. 11, the water outlet 32b is opened downward. In this way, the aqueous liquid from the water outlet 32b flows downward, reducing the scattering of the aqueous liquid.

[0071] In some embodiments, substances such as solid scale inhibitors, bactericides, and / or fragrances can also be arranged in the filtration chamber 322b to soften the water quality, remove bacteria, and / or increase the fragrance.

[0072] In some embodiments, referring to FIG. 11, the filter element 322 forms a cylindrical structure from a filter mesh, and the space within the cylindrical structure is the filtration chamber 322b. The entry of yarn waste into the filtration chamber 322b is restricted by the pore diameter of the filtration holes.

[0073] The above content is only a specific embodiment of the present disclosure, and the protection scope of the present disclosure is not limited thereto. Within the technical scope disclosed in the present disclosure, all modifications or substitutions that can be easily conceived by those skilled in the art should be included within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be subject to the protection scope of the claims.
