DETAILED DESCRIPTION

[0033] In order to more clearly understand the above objectives, features and advantages of the present application, the solutions of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0034] In the following description, a lot of specific details are set forth in order to fully understand the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the description are only some of the embodiments of the present application, not all the embodiments.

[0035] As Figure 1 shown, the embodiments of the present application provide a laundry treating apparatus, which is one of a washing machine, a drying machine and a washing-drying integrated machine.

[0036] The laundry treating apparatus comprises:

[0037] Box 1. Cylinder assembly 2, disposed within box 1. As an optional embodiment, cylinder assembly 2 includes an outer cylinder 21 fixedly installed within box 1 and an inner cylinder 22 rotatably installed within the outer cylinder 21; in other embodiments, cylinder assembly 2 includes only a rotatable cylinder.

[0038] A door seal is provided between the cylinder assembly 2 and the housing 1 to seal the gap between the housing 1 and the cylinder assembly 2. In one embodiment, the door seal is provided at the open end 341 of the outer cylinder 21 (that is, the front end of the outer cylinder 21), and the door seal and the inner cylinder 22 together enclose the clothing processing cavity 221; the door seal has a ring structure, and the clothes to be cleaned are placed from inside the door seal into the internal space of the inner cylinder 22.

[0039] Water inlet assembly 4 is used to supply water into the garment processing chamber 221;

[0040] The cleaning device 3 is installed inside the housing 1, and the cleaning device 3 includes a slow-release body 32. The cleaning device 3 is connected to the flow path of the water supplied by the water supply component 4. When the slow-release body 32 comes into contact with water, it releases cleaning substances and enters the clothing processing chamber 221 with the incoming water.

[0041] The slow-release agent 32 slowly dissolves and releases as water enters the garment processing equipment and enters the garment processing chamber 221 with the water to perform washing and cleaning effects. The slow-release agent 32 can be used for a long time and the release amount of the cleaning substance is stable, avoiding the problem of having to manually add the cleaning substance and having difficulty controlling the amount added.

[0042] The water inlet component 4 can be a water inlet valve, which is connected to the cleaning device 3 through a water inlet pipe, or located above the cleaning device 3. The water inlet component 4 can also be a faucet connected to a water source. It can also include a solenoid valve and a water inlet pipe. As long as the water inlet component 4 can deliver water to the cleaning device 3, it is acceptable. Those skilled in the art can set it according to the actual situation.

[0043] like Figures 1 to 7 As shown, in some embodiments of this application, the cleaning device 3 is disposed within the clothing processing chamber 221, specifically, as... Figures 1 to 5 As shown, it can be set on the inner surface of the door seal 5 or on the lifting rib 222 of the inner wall of the inner cylinder 22; when the cleaning device is set in the clothing processing cavity 221, the cleaning device 3 also includes a first box 34, the slow-release body 32 is set in the first box 34, and a plurality of evenly distributed first through holes 342 are set on the side wall of the first box 34 facing the clothing processing cavity 221 to form a first mesh structure.

[0044] For example, the cleaning device 3 is arranged on the inner surface of the door seal 5. One or more water inlets 501 are arranged on the side wall of the door seal 5 along the radial direction of the door seal 5 and penetrate the side wall of the door seal 5. The cleaning device 3 is arranged in correspondence with the water inlets 501. The first box body 34 is provided with an open end 341. The open end 341 of the first box body is fastened to the inner side wall of the door seal 5 and arranged in correspondence with the water inlets 501. Water can enter the first box body 34 from the water inlets 501 and contact the slow-release body 32 (not shown in the figure) in the first box body 34, so that the slow-release body 32 is dissolved to release cleaning substances. The released cleaning substances enter the clothes treatment cavity 221 from the first through hole 342 to participate in the clothes treatment process.

[0045] It should be noted that the water inlets 501 arranged opposite to the first box body 34 can be water inlets for adding water during the washing process of the clothes treatment cavity 221. During the process of adding water into the clothes treatment cavity 221, the cleaning device 3 is necessarily passed through, that is, as long as water is added into the clothes treatment cavity 221, the cleaning device 3 will synchronously add cleaning substances into the clothes treatment cavity 221. The water inlets arranged opposite to the first box body 34 can also be water inlets arranged separately from the water adding program during the washing process and independent of each other. Water is added into the clothes treatment cavity 221 without flowing through the cleaning device 3. When it is necessary to add cleaning substances into the clothes treatment cavity 221, water needs to be supplied to the cleaning device 3.

[0046] The cleaning device 3 can also be arranged in the lifting rib 222 of the inner tub 22.

[0047] Specifically, the lifting rib 222 has a cavity, which is in communication with the clothes treatment cavity 221. The slow-release body 32 is arranged in the cavity inside the lifting rib 222. When water is added into the clothes treatment cavity 221, the washing water enters the cavity and contacts the slow-release body, so that the slow-release body releases cleaning substances, which flow out of the water outlet of the lifting rib 222 into the clothes treatment cavity 221 to participate in the clothes treatment process.

[0048] In the foregoing embodiment, the cleaning device 3 is arranged on the inner side wall of the door seal 5. The first box body 34 is provided with an open end 341. The open end 341 is arranged in correspondence with the water inlets 501 of the clothes treatment cavity 221. Specifically, for example, the cleaning device 3 is arranged on the inner side wall of the door seal 5. A protruding annular connecting piece 51 is arranged on the side wall of the door seal 5. The profile of the annular connecting piece 51 matches the open end of the box body. A stepped surface 3411 is arranged on the inner wall of the first box body 34. The annular connecting piece 51 cooperates with the stepped surface 3411 to achieve the fastening and fixation of the box body to the door seal 5. When the slow-release body 32 needs to be replaced, the first box body 34 only needs to be detached from the door seal 5.

[0049] In some embodiments of this application, the cleaning device 3 may also be disposed between the housing 1 and the cylindrical assembly 2. Specifically, the cleaning device 3 is fixed to the outer cylinder 21 or to other structures between the housing 1 and the outer cylinder 212.

[0050] For example, the cleaning device is fixed to the inner side wall of the housing, which is surrounded by six side walls: the upper side wall, the lower side wall, the front side wall, the rear side wall, the left side wall, and the right side wall. The cleaning device can be installed on any of the side walls. The housing also includes a frame and a base that make up the housing, and the cleaning device can also be installed on the frame or the base of the housing.

[0051] For example, such as Figure 8 As shown, the second box 31 includes a box body and a box lid. Figure 4 (Not shown), the upper end of the box body is open, and the box lid fits onto the upper opening of the box body. The slow-release agent 32 can be placed into the interior of the box body from the upper end. A first connecting lug and a second connecting lug extend outward from the outer wall of the upper end of the box body. The box lid fits onto the upper end of the box body, and a third connecting lug is provided on the box lid at a position corresponding to the first connecting lug. The third connecting lug is connected to the first connecting lug by fasteners, so that the box lid is fixedly connected to the box body. The connecting hole on the second connecting lug is used for fixed connection with the upper crossbeam 101.

[0052] In some embodiments of this application, the cleaning device 3 may also be applied to the outer wall of the outer cylinder 21.

[0053] In some embodiments of this application, a receiving cavity is formed within the second housing 31, and a slow-release agent 32 is disposed within the receiving cavity. The second housing 31 is provided with a first water inlet 311 and a first water outlet 312. The first water inlet 311 is connected to the water inlet assembly 4 via a first connecting pipe 7, and the first water outlet 312 is connected to the water inlet of the clothing processing chamber 221 via a second connecting pipe 8. Water flows into the receiving cavity through the water inlet assembly 4 and the first water inlet 311 and comes into contact with the slow-release agent 32. After encountering water, the slow-release agent 32 slowly releases cleaning substances that flow out from the first water outlet 312 and enter the clothing processing chamber 221 through the second connecting pipe 8 to treat the clothing in the clothing processing chamber 221 accordingly.

[0054] For example, the first water inlet 311 is located at the upper rear side of the box body, and the first water outlet 312 is located at the lower front side of the second box body 31. After the water enters the box body through the first water inlet 311, it flows downward under the total force of gravity and finally flows out from the first water outlet 312. During the process of the water flowing in the second box body 31, it fully contacts the slow-release body 32, causing the slow-release body 32 to release cleaning substances.

[0055] It should be noted that in some embodiments of the present application, the positions of the first water inlet 311 and the first water outlet 312 are not particularly limited, and the first water inlet 311 can also be located below the first water outlet 312. The water in the second box body 31 can also flow from the first water inlet 311 to the first water outlet 312 by the action of the pump.

[0056] The water inlet of the laundry treatment cavity 221 connected with the second connecting pipe 8 can be a water inlet of the laundry treatment cavity 221 for water inlet, or a separate inlet which is communicated to the laundry treatment cavity 221. In this case, water inlet into the laundry treatment cavity 221 and the introduction of the slow-release cleaning substance can be carried out separately and do not affect each other.

[0057] In some embodiments of the present application, the laundry treatment apparatus further comprises a detergent box 6 connected between the water inlet assembly 4 and the laundry treatment cavity 221 for providing detergent to the laundry treatment cavity 221. The detergent box 6 can define a storage space therein so as to store the detergent in the detergent box 6. The dispensing assembly can be the controlled flow of the detergent in the detergent box 6 to the laundry treatment cavity 221.

[0058] In some embodiments of the present application, the cleaning device 3 and the detergent box 6 are connected in parallel between the water inlet assembly 4 and the laundry treatment cavity 221. Specifically, the first water inlet 311 of the second box body 31 is connected with the water inlet assembly 4 through the first connecting pipe 7, and the first water outlet 312 of the box body is connected to the laundry treatment cavity 221 through the second connecting pipe 8; the detergent box 6 is provided with a second water inlet and a second water outlet, the second water inlet is connected with the water inlet assembly 4 through a third connecting pipe, and the second water outlet is connected to the laundry treatment cavity 221 through a fourth connecting pipe.

[0059] Alternatively, the cleaning device 3 and the detergent box 6 are connected in series between the water inlet assembly 4 and the laundry treatment cavity 221. Specifically, the cleaning device 3 can be connected between the water inlet assembly 4 and the detergent box 6, and water first enters the cleaning device 3 through the water inlet assembly 4, slowly dissolves and releases the slow-release body 32, and then enters the detergent box 6 with the water flow, mixes with the detergent, and then enters the laundry treatment cavity 221; the cleaning device 3 can also be connected between the detergent box 6 and the laundry treatment cavity 221; water first enters the detergent box 6 through the water inlet assembly 4, and the mixed solution of the detergent and water slowly dissolves the slow-release body 32 in the cleaning device 3, and then enters the laundry treatment cavity 221.

[0060] Alternatively, the cleaning device 3 is arranged inside the detergent box 6. The detergent box 6 is connected between the water inlet assembly 4 and the clothes treatment cavity 221, the first water inlet port 311 and the first water outlet port 312 are arranged on the second box body 31, the first water inlet port 311 is arranged opposite to the water inlet port of the detergent box 6, and the first water outlet port 312 is arranged opposite to the water outlet port of the detergent box 6. Water from the water inlet assembly 4 enters the detergent box 6 from the water inlet port of the detergent box 6, is mixed with the detergent in the detergent box 6 on one hand, and enters the box body of the cleaning device 3 through the first water inlet port 311 on the other hand, reacts with the slow-release body 32 in the second box body 31, the slow-release body 32 slowly releases cleaning substances, the cleaning substances flow out of the box body through the first water outlet port 312, are mixed with the detergent in the detergent box 6, and then are discharged through the water outlet port of the detergent box 6 and then enter the clothes treatment cavity 221 to participate in the treatment of clothes.

[0061] It should be noted that the cleaning device 3 is arranged inside the detergent box 6, and can also be not communicated with the inside of the detergent box 6. The cleaning device 3 and the inside of the detergent box 6 are respectively connected by a connecting pipe for water inlet and water outlet. The detergent and the cleaning substances released by the slow-release body 32 are respectively introduced into the clothes treatment cavity 221 through the pipe. The time period of the detergent and the cleaning substances entering the clothes treatment cavity 221 can be selected according to actual needs in different clothes treatment programs.

[0062] In some embodiments of the present application, the slow-release body 32 comprises a shell and a slow-release substance in the shell, and a second through hole 321 is arranged on the wall of the shell.

[0063] Specifically, in some embodiments of the present application, the shell comprises a plurality of shell pieces, the plurality of shell pieces are connected to each other and jointly enclose a cavity, the slow-release substance is placed in the cavity, the plurality of shell pieces can be connected to each other in a clamping manner, facilitating the slow-release substance to be placed in and taken out of the cavity. A plurality of second through holes 321 are arranged on at least one side wall of the shell to form a second mesh structure. The plurality of second through holes 321 are uniformly distributed on the wall of the shell. No matter which direction of the shell is opposite to the first water inlet port 311 on the box body, water can be ensured to enter the cavity in time and contact the slow-release substance.

[0064] In some embodiments of the present application, a gap exists between the slow-release body 32 and the inner wall of the second box body 41. For example, the shell is rotatably arranged in the second box body 41, the slow-release substance has a block structure, and the slow-release substance is rotatably arranged in the shell. Under the action of water flow, the slow-release substance keeps rotating, the contact area with the water flow is increased, and the slow-release substance can be fully released.

[0065] For example, Figure 8 and Figure 10As shown, the inside of the second box body 41 forms a water immersion cavity, and the slow-release body is arranged in the water immersion cavity and is spaced apart from the inner wall of the box body. The shell has a shape similar to that of the second box body 41, and a plurality of fixing ribs 313 are arranged on the inner wall of the second box body 41. On the one hand, the fixing ribs 313 form positioning of the shell around the shell, avoiding the shell from shaking in the second box body 41. On the other hand, the fixing ribs 313 can form a gap between the outer wall of the shell and the inner wall of the second box body 41. The gap forms a water channel when water enters. The shell is immersed in water in the second box body 41, and then water can enter the inside of the shell through the perforations 321 on the shell to contact the slow-release material.

[0066] The shell is made of a material that is insoluble in water, and the slow-release material includes water-soluble excipients and functional materials. The water-soluble excipients and functional materials have a suitable volume ratio to ensure the structural stability of the slow-release structure and the release rate and efficacy of the functional materials. If the amount of the material insoluble in water is too large, i.e., the volume fraction of the water-soluble excipients and functional materials in the slow-release material is small, the volume fraction of the water-soluble excipients and functional materials is small, which will relatively reduce the use time of the slow-release material. Moreover, the internal skeleton of the material insoluble in water is relatively tight, which makes it difficult for the water-soluble excipients and functional materials inside the slow-release material to contact water, thereby making it difficult to dissolve or the dissolution rate being too slow, and weakening the effect of the functional materials. Conversely, if the amount of the shell is too small, i.e., the volume fraction of the material insoluble in water in the slow-release body 32 is small, and relatively more water-soluble excipients and functional materials are contained inside, the stability between the water-soluble excipients and the material insoluble in water is relatively poor, and the dissolution rate of the water-soluble excipients and functional materials is too fast, which easily causes waste of materials. The above-mentioned amounts of functional materials and water-soluble excipients can make the functional materials uniformly dispersed in the water-soluble excipients, and the concentration of the functional materials in the water-soluble excipients is better, and then the functional materials are effectively released with the dissolution of the water-soluble excipients. As can be seen, by controlling the amounts of the above-mentioned components, the dissolution rate of the water-soluble excipients and functional materials can be controlled, which can meet the requirements of the functional materials of the slow-release material, and can avoid the functional materials from dissolving too fast and causing waste of materials. The specific amount of the functional materials can be set by a person skilled in the art to be between 1 and 35 parts by weight according to the specific functional materials.

[0067] The water-soluble auxiliary material includes at least one of polyvinyl alcohol, polyethylene glycol and polyethylene oxide. The water-soluble auxiliary material of the above material has better solubility, can be slowly dissolved when water flows through, and does not have a chemical reaction with the functional material when water is encountered, thereby ensuring the stability of the slow-release material; meanwhile, the safety of the above material is better, and after being dissolved in water, the above material does not have an impact on clothes; in addition, because the solubility of different water-soluble auxiliary materials in water is different, in the embodiments of the present application, the dissolution rate of the dissolution part can also be controlled by selecting different specific types of water-soluble auxiliary materials to meet different application requirements and application environments of the slow-release material.

[0068] The shell is made of at least one of plastic (such as polyethylene, polypropylene, polylactic acid), rubber and fiber. The shell formed by the above material has better stability and is not easy to deform under the impact of a certain water flow; and the shell formed by the above material is stable in nature and is not easy to deteriorate; a chemical bond can be formed between the shell formed by the above material and the water-soluble auxiliary material formed by the above material, thereby improving the stability of the slow-release structure.

[0069] In some embodiments of the present application, the cleaning slow-release material is a detergent. As an optional implementation, the slow-release body can further include at least one of a bactericide, a softener, a fragrance, an anti-wrinkle agent, an anti-bleeding agent, a color fixing agent, an odor removing agent, a solid enzyme preparation, a water softener and a scale remover used in combination with the detergent.

[0070] In summary, the laundry treatment device provided by the embodiments of the present application can flush the slow-release body 32 by arranging the cleaning device 3 on the water inlet path, so that the slow-release body 32 slowly releases the cleaning material and enters the laundry treatment cavity 221 with the water, the cleaning device 3 can be used multiple times at a time, meets the treatment of the laundry in different laundry treatment procedures, and avoids the problem that the cleaning material needs to be manually put in and the amount of the cleaning material is difficult to control.
