The inner drum 50 has a clothing washing chamber. During the process of washing clothes, the inner drum 50 can rotate relative to the outer drum 40 to wash the clothes in the clothing washing chamber. The clothing washing chamber is connected to the interior of the outer drum 40. For example, a plurality of through holes may be provided on the inner drum 50, and the plurality of through holes may be evenly distributed on the wall of the inner drum 50. The water in the clothing washing chamber may flow into the outer drum 40 through the through holes on the wall of the inner drum 50, and may be discharged from the outer drum 40 after washing.

[0068] See also Figure 1 As shown, the laundry processing device 10 may further include a door body 30. The door body 30 is connected to the housing 20 to cover the laundry access opening. For example, the door body 30 may be provided at the laundry access opening and rotatably connected to the housing 20 so that the door body 30 can cover the laundry access opening, and at the same time, the door body 30 can be easily opened so that the laundry can be put into the inner drum 50 through the laundry access opening, and the laundry can be washed by the laundry processing device 10.

[0069] See also Figure 1 As shown, the clothes treating apparatus 10 may further include a door seal 60. The door seal 60 may be disposed between the tube opening of the outer drum 40 and the door body 30 to seal the gap between the door body 30 and the tube opening of the outer drum 40. The door body 30 may be a glass door body 30 so that the user can observe the condition of the clothes in the inner drum 50 through the door body 30.

[0070] The laundry processing device 10 may further include a water inlet pipe (not shown). A portion of the water inlet pipe may be disposed inside the housing 20, and another portion may be disposed outside the housing 20, so that the water inlet pipe is connected to an external water source (such as a faucet). Water is injected into the inner drum 50 through the water inlet pipe, and at the same time, the water flowing through the water inlet pipe can bring detergent into the inner drum 50, so that the laundry processing device 10 can wash the clothes with the cooperation of water and detergent.

[0071] See also Figure 1 As shown, the laundry treatment apparatus 10 may further include a drain pipe 80. A portion of the drain pipe 80 is disposed inside the housing 20, and another portion is disposed outside the housing 20, so as to drain liquid to the outside of the housing 20.

[0072] The clothes treating apparatus 10 may further include a drain pump 70. The drain pump 70 is disposed in the housing 20 and may be connected to the outer tub 40 so that the liquid in the outer tub 40 can enter the outer tub 40, and the drain pump 70 can pump the liquid in the outer tub 40 into the drain pipe 80. The water inlet end of the drain pump 70 may be connected to the drain port of the outer tub 40 to achieve the connection between the drain pump 70 and the outer tub 40.

[0073] The laundry processing device 10 has a laundry processing program. The laundry processing program includes a washing program, a rinsing level, etc. When the laundry processing program is a washing program, the liquid formed by the mixture of water and detergent in the inner drum 50 and the outer drum 40 can be referred to as washing water. When the laundry processing program is a rinsing level, the liquid in the inner drum 50 and the outer drum 40 can refer to the water in the inner drum 50 and the outer drum 40, or a mixed liquid formed by the mixture of water and a whitening agent, etc.

[0074] The clothing processing device 10 may further include a heater, which can heat the liquid in the inner drum 50 so as to achieve the function of heating and washing the clothing by the clothing processing device 10 and improve the cleaning effect of the clothing processing device 10 on the clothing.

[0075] However, the existing clothes treatment equipment takes a long time to wash without heating, and the washing effect is poor. Moreover, after the washing is completed, detergent foam and other impurities may remain in the door and other places. Over time, these residual impurities will become moldy and smelly, resulting in poor washing effect of clothes, which affects the health of users.

[0076] To this end, a circulation pipeline 90 is further provided in the laundry processing device 10. The circulation pipeline 90 and the water inlet pipeline can be used as two different liquid inlet pipelines. In other words, the liquid inlet pipeline includes the water inlet pipeline and the circulation pipeline 90. At least part of the liquid inlet pipeline is arranged in the housing 20. For example, when the liquid inlet pipeline is the circulation pipeline 90, the circulation pipeline 90 can be partially arranged in the housing 20, or it can be completely arranged in the housing 20. The arrangement of the water inlet pipeline in the housing 20 can refer to the relevant description above.

[0077] The circulation pipeline 90 may be communicated with the interior of the outer cylinder 40 , so that the liquid in the inner cylinder 50 and the outer cylinder 40 may enter the circulation pipeline 90 .

[0078] The clothing treatment device 10 may further include a spray pipe 110. The spray pipe 110 may be used to communicate with the water outlet of the liquid inlet pipeline. For example, when the liquid inlet pipeline is a circulation pipeline 90, the circulation pipeline 90 can introduce the liquid discharged from the inner drum 50 and the outer drum 40 into the spray pipe 110. The spray pipe 110 may be installed on the door seal 60.

[0079] The clothing processing device 10 may also include a spray head 120. The spray head 120 has a spray hole 121. The liquid entering the spray pipe 110 can be sprayed into the inner drum 50 through the spray hole 121. The spray head 120 can spray liquid (such as washing water) onto the clothes, effectively flushing the clothes in the inner drum 50, so that the clothes can be better soaked in the clothes, so that the liquid can better disperse the stains attached to the surface of the clothes, thereby improving the cleaning effect. In addition, the spray head 120 can spray liquid onto the clothes, and the liquid can also hit the clothes, effectively reducing the entanglement between the clothes, improving the cleaning effect, and at the same time, protecting the quality of the clothing fabric.

[0080] The washing water entering the shower head 120 generally contains lint. After the laundry treatment apparatus 10 is used for a long time, the lint is likely to gather in the shower head 120 and clog the shower head 120.

[0081] However, the existing spray head is fixedly connected to the water outlet end of the spray pipe, which makes it difficult to disassemble the spray head from the spray pipe and to clean the wire scraps accumulated in the spray head.

[0082] In view of this, see Figure 1 As shown, the embodiment of the present application also provides a spray assembly 100. The clothing processing device 10 of the embodiment of the present application may include a spray assembly 100. The spray assembly 100 includes a spray pipe 110, a fixing member 130 and a spray head 120, and the fixing member 130 is installed at the water outlet end of the spray pipe 110. The spray head 120 can be installed in the fixing member 130 by means of a clamping or screwing of a clamping member 140, so as to realize the detachable installation of the spray head 120 at the water outlet end of the spray pipe 11-. The user can release the clamping of the spray head 120 and the fixing member 130, or can realize the quick disassembly of the spray head 120 by screwing, so as to facilitate the user to clean and wash the impurities such as wire scraps in the spray head 120, prevent the spray head 120 from blocking or the dirt attached to its surface from contaminating the washing water, affecting the washing effect, and at the same time, can improve the user experience.

[0083] It should be noted that the spray assembly 100 can be installed at the water outlet end of the liquid inlet pipeline. For example, the spray pipe 110 can be installed at the water outlet end of the liquid inlet pipeline and can be connected to the water outlet end of the liquid inlet pipeline.

[0084] As described above, the liquid inlet pipeline may include a circulation pipeline 90, a water inlet pipeline or other liquid inlet channels in the laundry processing device 10. When the liquid inlet pipeline is the circulation pipeline 90, the liquid (such as washing water) in the inner drum 50 and the inner and outer drums 40 may be sprayed into the inner drum 50 via the spray assembly 100, effectively washing the clothes in the inner drum 50, so that the clothes can be better soaked in the washing water, so that the liquid can better disperse the stains attached to the surface of the clothes, thereby improving the cleaning effect.

[0085] When the liquid inlet pipeline is a water inlet pipeline, the liquid in the liquid inlet pipeline is water that can flow into the water inlet pipeline from an external water source. The water inlet pipeline includes a water inlet pipe, a water inlet valve and a water inlet pipe branch. The water inlet pipe is connected to an external water source, and the water inlet valve is arranged between the water inlet pipe and the water inlet pipe branch. The water in the water inlet pipe can enter the water inlet pipe branch through the water inlet valve, and the water outlet end of the water inlet pipe branch is connected to the spray assembly 100. The water flowing through the water inlet pipe branch can bring the detergent into the inner drum 50, and spray it into the inner drum 50 through the spray assembly 100, which can also better soak the clothes and help the detergent to better disperse the stains attached to the surface of the clothes, thereby improving the cleaning effect.

[0086] It should be noted that the connection between the water inlet pipe, the water inlet valve and the water inlet pipe branch can be determined according to the structure of the clothing processing device 10 in the relevant technology, and will not be repeated in this application.

[0087] The following uses the liquid inlet pipeline as the circulation pipeline 90 as an example to further explain the structures of the clothing processing device 10 and the spray assembly 100.

[0088] Figure 2 The structural diagram of the first spray assembly provided in the embodiment of the present application is schematically shown.

[0089] Combine the following Figure 2 The structure of the first spray assembly and the clothes processing device 10 are further described.

[0090] See also Figure 2 As shown, the spray assembly 100 may include a spray pipe 110. The spray pipe 110 may be used to communicate with the water outlet end of the liquid inlet pipeline so that the liquid in the liquid inlet pipeline can enter the spray pipe 110.

[0091] The spray assembly 100 may include a fixing member 130 and a spray head 120. The fixing member 130 may be installed at the water outlet end of the spray pipe 110. The fixing member 130 has a cavity 1301 therein. The cavity 1301 is connected to the water outlet end of the spray pipe 110.

[0092] The spray assembly 100 may include a spray head 120. The spray head 120 may be disposed in the fixing member 130, and the spray head 120 may have a through hole and a spray hole 121. The spray hole 121 is connected to the cavity 1301 and faces the inner drum 50. In this way, the spray head 120 may be connected to the liquid inlet pipeline through the fixing member 130 and the spray pipe 110, so that the liquid in the liquid inlet pipeline may flow to the spray pipe 110, the cavity 1301 and the spray hole 121 in sequence, and finally the liquid is sprayed to the inner drum 50 through the spray hole 121, and the clothes are wetted to improve the washing effect.

[0093] In addition, part of the door body 30 usually protrudes toward one side of the inner drum 50, and the door seal 60 is located on the peripheral side of the protruding part of the door body 30. Therefore, the liquid sprayed by the spray head 120 to the inner drum 50 can not only flush the inner drum 50 in a larger area, but also flush the door body 30, the door seal 60, etc. in a larger area, so that the inner drum 50, the door seal 60, the door body 30, etc. are effectively flushed to avoid impurities such as foam generated by detergent from remaining in the inner drum 50, the door seal 60, and the door body 30, thereby improving the cleaning effect and ensuring the health of clothing users.

[0094] See also Figure 1 As shown, the spray pipe 110 can be passed through the door seal 60 and arranged on the side of the door seal 60 facing the top of the clothing processing device 10. For example, the spray pipe 110 can be passed through the door seal 60 and can face the side of the top of the housing 20. The spray head 120 is exposed on the inner side of the door seal 60 to facilitate the removal of the spray head 120. At the same time, the user can see the spray head 120 from the side facing the door seal 60, so that the water flow sprayed by the spray head 120 has the characteristic of visualization, so that the user can directly see the water flow effect sprayed by the spray head 120.

[0095] It should be noted that the inner side of the door seal 60 can be understood as the side of the door seal 60 facing the tube opening of the outer tube 40 along the radial direction of the outer tube 40 .

[0096] See also Figure 1 As shown, in some embodiments, the laundry processing device 10 may further include a connecting device. The connecting device may be a three-way valve or the like. The connecting device is disposed in the housing 20. The connecting device may selectively connect the water outlet of the drain pump 70 to the water inlet of the circulation pipeline 90 and the water inlet of the drain pipe 80.

[0097] When the mixture in the inner drum 50 and the outer drum 40 needs to be circulated and sprayed, the connecting device can connect the water outlet of the drain pump 70 with the water inlet of the circulation pipeline 90 and the water inlet of the drain pipe 80. The drain pump 70 is started, and the drain pump 70 pumps the mixture in the inner drum 50 and the outer drum 40 into the circulation pipeline 90, and directly reaches the spray head 120 upward. The mixture sprayed from the spray head 120 can wash the wall of the inner drum 50, the clothes in the inner drum 50, the door body 30, and the door seal 60.

[0098] When it is necessary to discharge the mixture in the inner cylinder 50 and the outer cylinder 40 to the outside of the housing 20, the connecting device can connect the water outlet of the drain pump 70 with the water inlet of the drain pipe 80. When the drain pump 70 is started, the drain pump 70 pumps the mixture in the inner cylinder 50 and the outer cylinder 40 into the drain pipe 80, and the mixture can be discharged to the outside of the housing 20 through the drain pipe 80.

[0099] It should be noted that the structure of the communication device can be determined according to the structure of the clothing processing device 10 in the related art, and will not be described in detail in this application. During the washing, rinsing and dehydration process of the clothing processing device 10, the liquid in the liquid inlet pipeline can be sprayed out from the spray hole 121 at any time according to the program design of the clothing processing device 10 to flush the wall of the inner drum 50, the clothes in the inner drum 50, the door body 30, and the door seal 60.

[0100] See also Figure 2 As shown, in some embodiments, the spray assembly 100 may further include a clamping member 140 . The clamping member 140 may be inserted into the insertion hole and clamped with the fixing member 130 to install the spray head 120 in the fixing member 130 .

[0101] The clamping member 140 can realize the clamping connection between the spray head 120 and the fixing member 130, so that the spray head 120 can be installed in the fixing member 130 through the clamping member 140, and then the spray head 120 can be detachably installed on the water outlet end of the spray pipe 110 through the fixing member 130. When the spray head 120 needs to be disassembled, the user can release the clamping connection between the spray head 120 and the fixing member 130, so as to realize the rapid disassembly of the spray head 120, so as to facilitate the user to clean and wash the impurities such as wire scraps in the spray head 120, prevent the spray head 120 from being blocked or the dirt attached to its surface from contaminating the washing water, affecting the washing effect, and at the same time, improve the user experience.

[0102] The clamping member 140 may be a flexible member or a non-flexible member. When the clamping member 140 is a flexible member, when the shower head 120 needs to be disassembled, the user can act on the flexible member to deform the flexible member so that the flexible member can be smoothly removed from the hole. After the flexible member is removed from the hole, the clamping connection between the shower head 120 and the fixing member 130 can be released, thereby realizing the rapid disassembly of the shower head 120, so as to facilitate the user to clean and wash the impurities such as wire scraps in the shower head 120, prevent the shower head 120 from being blocked or the dirt attached to its surface from contaminating the washing water, affecting the washing effect, and at the same time, can improve the user experience.

[0103] The following text takes the clamping member 140 as an example of a flexible member to further define the structure of the clamping member 140 .

[0104] The clamping member 140 may be a rubber member with a certain hardness, or a plastic member with a certain flexibility.

[0105] See also Figure 2 As shown, in some embodiments, when the clamping member 140 is a flexible member, a clamping portion 141 and a pressing portion 142 may be respectively provided at two ends of the clamping member 140 .

[0106] Figure 3 Indicated Figure 2Top view in the aa direction.

[0107] See also Figure 2 and Figure 3 As shown, the fixing member 130 may have a clamping portion 1303, and the clamping portion 1303 is located on the side of the spray head 120 facing the spray pipe 110. The clamping portion 141 may be clamped on the side of the clamping portion 1303 facing the spray pipe 110. Through the cooperation of the clamping portion 141 and the clamping portion 1303, the clamping member 140 can be installed on the fixing member 130.

[0108] See also Figure 2 As shown, in some embodiments, the side of the spray head 120 facing the spray pipe 110 may have a mounting portion 1201. The mounting portion 1201 may be disposed in the fixing member 130. One side of the mounting portion 1201 may abut against the side of the clamping portion 1303 away from the spray pipe 110, and the pressing portion 142 abuts against the other side of the mounting portion 1201, so that the mounting portion 1201 can be installed in the fixing member 130 and fixed relatively to the fixing member 130 through the cooperation of the clamping portion 1303 and the pressing portion 142, thereby realizing the detachable installation of the spray head 120 in the fixing member 130.

[0109] By setting the pressing portion 142, the user can press the pressing portion 142 to deform the pressing portion 142 when removing the shower head 120. At this time, the pressing portion 142 cannot press against the other side of the mounting portion 1201. Without the pressing portion 142 pressing against the mounting portion 1201, the mounting portion 1201 can be directly removed from the fixing member 130, so that the shower head 120 can be quickly removed.

[0110] See also Figure 2 As shown, the spray head 120 has a spray portion 1202 on a side away from the spray pipe 110. A spray hole 121 may be provided on the spray portion 1202. The axial direction of the spray hole 121 may be arranged at an angle with the length direction of the fixing member 130, so that the axial direction of the spray hole 121 is inclined toward the side away from the clamping member 140, so as to expand the spray area of ​​the spray hole 121, thereby expanding the spray area of ​​the spray hole 121 and the spray assembly 100, and improving the cleaning effect. The length direction of the fixing member 130 is parallel to the W direction.

[0111] The spraying region of the spraying assembly 100 may include the spraying region of the spraying hole 121. Accordingly, the spraying area of ​​the spraying assembly 100 may include the area occupied by the spraying region of the spraying hole 121.

[0112] See also Figure 3As shown, in some embodiments, the number of the spray holes 121 can be multiple. For example, the number of the spray holes 121 can be two, three, four, etc. Along the circumference of the spray head 120, the multiple spray holes 121 can be evenly distributed on the spray part 1202, so that the water flow generated by the liquid in the liquid inlet pipeline spraying through the spray holes 121 is more uniform, so as to further expand the spray area of ​​the spray assembly 100, so as to achieve a large area coverage of the clothes in the inner drum 50, improve the washing effect, and at the same time, can wash the inner drum 50, the door seal 60, and the door body 30 over a large area, improve the washing effect, and ensure the health of the clothes user.

[0113] See also Figure 2 and Figure 3 As shown, in some embodiments, the fixing member 130 may include a first fixing portion 1304, a second fixing portion 1305 and a connecting rib that are connected to each other. The first fixing portion 1304 may be installed at the water outlet end of the spray pipe 110. For example, the first fixing portion 1304 may be installed at the water outlet end of the spray pipe 110 by means of a threaded connection, a clamping connection or a welding structure. The second fixing portion 1305 may be arranged in the first fixing portion 1304 and connected to the first fixing portion 1304 by means of a connecting rib. The circumferential outer wall of the second fixing portion 1305 and the circumferential inner wall of the first fixing portion 1304 together form a cavity 1301. The first fixing portion 1304 has a connecting hole at one end facing the spray pipe 110, and the cavity 1301 may be connected to the spray pipe 110 through the connecting hole.

[0114] The mounting portion 1201 is disposed in the second fixing portion 1305, and the second fixing portion 1305 may have a clamping portion 1303 at one end facing the spray pipe 110. The clamping portion 1303 has a first opening, and the clamping portion 141 may penetrate the through hole and the first opening, and be clamped to the side of the clamping portion 1303 facing the spray pipe 110, so that the spray head 120 and the fixing member 130 can be detachably connected through the cooperation of the clamping portion 1303 and the pressing portion 142.

[0115] Figure 4 Schematically shows Figure 2 Schematic diagram of the disassembly process of the middle sprinkler head 120. Figure 2 and Figure 4 As shown, in order to facilitate the deformation of the clamping member 140, the clamping member 140 may have a cavity, and a second opening communicating with the cavity is provided in the clamping portion 141, so that when the pressing portion 142 is pressed, the pressing portion 142 can be deformed. Furthermore, when the user acts on the pressing portion 142 to pull the clamping member 140 out of the through hole, the clamping portion 141 can be deformed toward one side of the second opening, so that the clamping portion 141 contracts, so that the clamping portion 141 can pass through the through hole, and the clamping member 140 can be smoothly removed from the through hole, thereby realizing the rapid disassembly of the sprinkler head 120.

[0116] Figure 5 Schematically shows Figure 2 Schematic diagram of the installation process of the middle sprinkler head 120. Figure 2 and Figure 5 As shown, when the user installs the shower head 120, the installation portion 1201 of the shower head 120 can be first installed in the second fixing portion 1305, and then the clamping member 140 can be inserted into the insertion hole so that the clamping portion 141 abuts against the clamping portion 1303, and at the same time, the pressing portion 142 presses the installation portion 1201 to achieve the installation of the shower head 120 in the fixing member 130. Alternatively, the user can also first insert the clamping member 140 into the insertion hole, and then install the clamping member 140 and the shower head 120 together in the second fixing portion 1305, and achieve the clamping connection between the shower head 120 and the second fixing portion 1305 through the clamping member 140.

[0117] See also Figure 5 As shown, in some embodiments, the clamping member 140 may have a deformable connecting arm in the circumferential direction. The connecting arm may form a pressing portion 142. Alternatively, the end of the clamping member 140 away from the spray pipe 110 may form the pressing portion 142 as a whole. Compared with the end of the clamping member 140 away from the spray pipe 110 may form the pressing portion 142 as a whole, when the connecting arm forms the pressing portion 142, while ensuring that the pressing portion 142 can press against the mounting portion 1201, it is also convenient for the user to accurately press the pressing portion 142, so that the pressing portion 142 can be deformed faster, so as to further improve the disassembly efficiency of the spray head 120.

[0118] In some embodiments, the clamping member 140 may have at least two pressing portions 142. For example, the number of the pressing portions 142 may be two. At least two pressing portions 142 may be spaced and distributed around the circumference of the clamping member 140 so that the pressing portions 142 are subjected to a more uniform force, so that the pressing portions 142 can be deformed more quickly, thereby further improving the disassembly efficiency of the shower head 120. Alternatively, the number of the pressing portions 142 may be one, in which case the pressing portion 142 may be a closed structure arranged around the circumference of the clamping portion 141.

[0119] In some embodiments, the spray assembly 100 may have a spray hole. For example, the spray hole may include a first spray hole 143, a second spray hole 1203, etc. The liquid in the liquid inlet pipeline may also be sprayed to the inner cylinder 50 through the spray hole to expand the spray area of ​​the spray assembly 100, thereby expanding the spray area of ​​the spray assembly 100.

[0120] When the spray assembly 100 includes a spray hole, the spray area of ​​the spray assembly 100 also includes the spray area of ​​the spray hole in addition to the spray area of ​​the spray hole 121. Accordingly, the spray area of ​​the spray assembly 100 includes not only the area occupied by the spray area of ​​the spray hole 121, but also the area occupied by the spray area of ​​the spray hole.

[0121] Figure 6 The schematic diagram shows the water flow effect produced by the first type of spray assembly. Figure 6 As shown, in some embodiments, the clamping member 140 may have a first spray hole 143. The first spray hole 143 is connected to the cavity 1301 and faces the inner cylinder 50, so that the liquid in the liquid inlet pipeline can also be sprayed to the inner cylinder 50 through the first spray hole 143 to expand the spray area of ​​the spray assembly 100, thereby expanding the spray area of ​​the spray assembly 100 and improving the cleaning effect.

[0122] It should be noted that, in some embodiments, the first spray hole 143 may not be provided on the clamping member 140. The structure of the first spray assembly is further described below by taking the first spray hole 143 on the clamping member as an example.

[0123] See also Figure 6 As shown, in some embodiments, the end of the fixing member 130 away from the spray pipe 110 can be an open end 1302 connected to the cavity 1301. The spray part 1202 can be arranged in the open end 1302, and the circumferential outer wall of the spray part 1202 and the circumferential inner wall of the open end 1302 together form a second spray hole 1203. Among them, the second spray hole 1203 is connected to the cavity 1301 and faces the inner cylinder 50, so that the liquid in the liquid inlet pipeline can also be sprayed to the inner cylinder 50 through the second spray hole 1203, further expanding the spray area of ​​the spray assembly 100 and improving the cleaning effect. At the same time, since the second spray hole 1203 is located at the periphery of the spray hole 121, the spray hole 121 can cooperate with the second spray hole 1203 to enhance the flushing effect of the inner cylinder 50, the door seal 60, and the door body 30, further improve the cleaning effect, and ensure the health of the user.

[0124] See also Figure 6 As shown, in some embodiments, along the circumference of the spray head 120, there may be a gap between the circumferential outer wall of the spray portion 1202 and the circumferential inner wall of the open end 1302, and the circumferential outer wall of the spray portion 1202 and the circumferential inner wall of the open end 1302 may together form an annular hole. The annular hole forms the second injection hole 1203, so that the liquid in the liquid inlet pipeline can also be injected into the inner cylinder 50 through the second injection hole 1203.

[0125] The second spray hole 1203 may be a tapered hole having a small diameter end and a large diameter end, wherein the small diameter end faces the spray pipe 110 and the large diameter end faces the inner cylinder 50, so as to ensure that the liquid in the liquid inlet pipeline can also be sprayed to the inner cylinder 50 through the second spray hole 1203, and the spraying area of ​​the spray assembly 100 can be expanded.

[0126] See also Figure 6 As shown, the shape formed by the circumferential inner wall of the opening end 1302 can be a cone, which also has a small diameter end and a large diameter end, the small diameter end faces the spray pipe 110, and the large diameter end faces the inner cylinder 50. The shape formed by the circumferential outer wall of the spray part 1202 matches the shape formed by the circumferential inner wall of the opening end 1302.

[0127] It should be noted that the “shape of A matches the shape of B” mentioned in the present application can be understood as the shape of A being the same as or similar to the shape of B. For example, “the shape formed by the circumferential outer wall of the spraying portion 1202 matches the shape formed by the circumferential inner wall of the opening end 1302” can be understood as the shape formed by the circumferential outer wall of the spraying portion 1202 being the same as or similar to the shape formed by the circumferential inner wall of the opening end 1302. If there are similar descriptions below, this understanding can be made.

[0128] When the shape formed by the circumferential outer wall of the spray portion 1202 matches the shape formed by the circumferential inner wall of the opening end 1302 , the shape formed by the circumferential outer wall of the spray portion 1202 is also conical, and similarly the small diameter end faces the spray pipe 110 and the large diameter end faces the inner cylinder 50 .

[0129] Alternatively, the shape formed by the circumferential inner wall of the opening end 1302 may be cylindrical, and in this case, the shape formed by the circumferential outer wall of the spray portion 1202 may also be cylindrical.

[0130] Compared with the cylindrical shape formed by the circumferential inner wall of the opening end 1302, when the shape formed by the circumferential inner wall of the opening end 1302 is conical, while ensuring that the liquid in the liquid inlet pipeline is sprayed into the inner cylinder 50 through the second spray hole 1203, the spraying area of ​​the second spray hole 1203 and the spray assembly 100 can be expanded, thereby expanding the spraying area of ​​the second spray hole 1203 and the spray assembly 100.

[0131] In some embodiments, along the circumference of the spray head 120 , the gap between the circumferential outer wall of the spray portion 1202 and the circumferential inner wall of the opening end 1302 can also be divided into a plurality of independent small second spray holes 1203 , which can also spray the liquid in the liquid inlet pipeline into the inner cylinder 50 .

[0132] Compared with the multiple second injection holes 1203 between the circumferential outer wall of the spray part 1202 and the circumferential inner wall of the opening end 1302, when the circumferential outer wall of the spray part 1202 and the circumferential inner wall of the opening end 1302 jointly form a second injection hole 1203, the liquid in the liquid inlet pipeline can have a larger flow space in the second injection hole 1203, and impurities such as wire scraps are not easy to clog the second injection hole 1203.

[0133] On the basis of the above, the embodiment of the present application further provides a second spray assembly. Different from the first spray assembly mentioned above, in the second spray assembly, the spray head 120 is screwed into the fixing member 130 to achieve a detachable connection between the spray head 120 and the fixing member 130, and at the same time, the spray head 120 can open or block the second spray hole 1203 during the screwing process, so that the spray assembly 100 can spray water flow of different forms and intensities, so that the user can independently select the type of water flow according to personal needs or the type of clothes to be washed.

[0134] The differences of the second spray assembly are further described below in conjunction with the accompanying drawings and embodiments.

[0135] Figure 7 The schematic diagram shows the structure of the second spray assembly when the second spray hole 1203 is opened. Figure 8 The schematic diagram shows the structure of the second spray assembly when the second spray hole 1203 is gradually blocked. Fig. 9 The schematic diagram shows the structure of the second spray assembly when the second spray hole 1203 is blocked.

[0136] See also Figures 7 to 9 As shown, as described above, the fixing member 130 has an open end 1302 connected to the cavity 1301 at one end away from the spray pipe 110. In some embodiments, the spray head 120 can be screwed into the fixing member 130 and fixed relatively to the fixing member 130. In other words, the spray head 120 is screwed into the fixing member 130, and the positions of the spray head 120 and the fixing member 130 are relatively fixed without the action of external force. For example, the mounting portion 1201 of the spray head 120 can be arranged in the second fixing portion 1305 and threadedly connected to the second fixing portion 1305, so that the spray head 120 is screwed into the fixing member 130, and at the same time, it can be ensured that the spray head 120 is relatively fixed to the second fixing portion 1305 without the action of external force.

[0137] The mounting portion 1201 may be provided with an external thread, and the second fixing portion 1305 may be provided with an internal thread, so that when the mounting portion 1201 is disposed in the second fixing portion 1305 , a threaded connection between the mounting portion 1201 and the second fixing portion 1305 can be achieved.

[0138] The spray part 1202 is disposed in the open end 1302, and the circumferential outer wall of the spray part 1202 and the circumferential inner wall of the open end 1302 can together form a second spray hole 1203. The spray part 1202 has a spray hole 121, and the shape of the spray hole 121 can be different from the second spray hole 1203. The spray hole 121 and the second spray hole 1203 are both connected to the cavity 1301 and face the inner cylinder 50, so that the liquid in the liquid inlet pipeline can enter the inner cylinder 50 through the spray hole 121 and the second spray hole 1203.

[0139] The mounting portion 1201 is a hollow structure communicating with the spray hole 121 and the cavity 1301 of the fixing member 130 , so that the spray hole 121 is communicated with the cavity 1301 through the mounting portion 1201 .

[0140] The second spray hole 1203 can be opened or blocked during the process of the spray head 120 being screwed into the fixing member 130 .

[0141] Since the spray head 120 is screwed into the fixing part 130, when the user needs to remove the spray head 120, the user can rotate the spray part 1202 to rotate the mounting part 1201 relative to the fixing part 130 toward the end away from the fixing part 130, and unscrew it from the second fixing part 1305, so as to release the connection between the spray head 120 and the fixing part 130, thereby realizing the rapid disassembly of the spray head 120, so as to facilitate the user to clean and wash the impurities such as lint in the spray head 120, prevent the spray head 120 from being blocked or the dirt attached to its surface from contaminating the washing water and affecting the washing effect, and at the same time, can improve the user experience.

[0142] Fig.10 The partial structural diagram of the second spray assembly in the clothes processing device 10 is schematically shown.

[0143] See also Fig. 9 and Fig.10 As shown, in some embodiments, the spray portion 1202 may have a recessed structure 1204 that is recessed toward one side of the spray pipe 110 , so that a user can act on the recessed structure 1204 of the spray portion 1202 to achieve rapid disassembly and assembly of the spray head 120 .

[0144] See also Figures 7 to 9As shown, since the second spray hole 1203 can be opened or blocked during the process of the spray head 120 being screwed into the fixing member 130, the liquid in the liquid inlet pipeline can enter the inner drum 50 through the spray hole 121 and the second spray hole 1203 at the same time during the process of the spray head 120 being screwed into the fixing member 130, or can enter the inner drum 50 only through the spray hole 121. The spray assembly 100 can form water flows of different forms and intensities, so that the user can independently select the type of water flow according to personal needs or the type of clothes to be washed.

[0145] The structure of the spray assembly 100 is further described below by taking the example of a user autonomously selecting the type of water flow according to the type of clothes to be washed.

[0146] For example, see Figure 7 As shown, when the spray head 120 is screwed into the fixing member 130 and the second spray hole 1203 is opened, the liquid in the liquid inlet pipeline can enter the inner drum 50 through the spray hole 121 and the second spray hole 1203 at the same time. At this time, a dispersed water flow can be formed, and the pressure of the water flow is relatively small, which is suitable for washing clothes that require a gentle water flow.

[0147] For example, see Fig. 9 As shown, when the spray head 120 is screwed into the fixing member 130 and the second spray hole 1203 is blocked, the liquid in the liquid inlet pipeline can only enter the inner drum 50 through the spray hole 121. At this time, the water flow is more concentrated and the water pressure is relatively large, which is suitable for washing clothes that require strong water flow.

[0148] See also Figure 7 and Fig. 9 As shown, the shower head 120 is screwed into the fixing member 130 and has an open position and a blocked position.

[0149] See also Figure 7 As shown, when the spray head 120 is in the open position, along the circumference of the spray head 120, there is a gap connected to the outside between the circumferential outer wall of the spray part 1202 and the circumferential inner wall of the open end 1302 to open the second injection hole 1203, so that the liquid in the liquid inlet pipeline can enter the inner cylinder 50 through the spray hole 121 and the second injection hole 1203 at the same time, forming a dispersed water flow with low pressure.

[0150] See also Fig. 9 As shown, when the spray head 120 is in the blocking position, along the circumference of the spray head 120, the circumferential outer wall of the spray portion 1202 contacts the circumferential inner wall of the opening end 1302 to block the second injection hole 1203, so that the liquid in the liquid inlet pipeline can only enter the inner cylinder 50 through the spray hole 121, forming a more concentrated and high-pressure water flow.

[0151] See also Fig. 9As shown, similar to the first type of spray assembly, the shape formed by the circumferential inner wall of the opening end 1302 is also conical, wherein the small diameter end may face the spray pipe 110, and the large diameter end may face the inner cylinder 50. The shape formed by the circumferential outer wall of the spray portion 1202 may match the shape formed by the circumferential inner wall of the opening end 1302. In other words, the shape formed by the circumferential outer wall of the spray portion 1202 may also be conical, and have a small diameter end and a large diameter end.

[0152] The difference is that when the shower head 120 is in the blocking position, the circumferential outer wall of the shower part 1202 and the circumferential inner wall of the opening end 1302 are in conical contact, so as to block the second spray hole 1203 by the cooperation between the shower part 1202 and the opening end 1302. For example, the large diameter end of the circumferential outer wall of the shower part 1202 can be in conical contact with the circumferential inner wall of the opening end 1302.

[0153] It should be noted that when the spray head 120 is in the open position, the large diameter end of the circumferential outer wall of the spray portion 1202 can be located outside the opening end 1302, so that the large diameter end of the circumferential outer wall of the spray portion 1202 can protrude from the fixing part 130, so that the user can quickly find the fixing part 130 and realize the rapid disassembly of the spray head 120.

[0154] See also Figures 7 to 9 As shown, when the user needs concentrated and high-pressure water flow, the user can rotate the spray head 120 so that the spray head 120 is screwed toward the side close to the spray pipe 110. During the screwing process, the large-diameter end of the cone formed by the circumferential outer wall of the spray part 1202 continuously moves toward the side close to the spray pipe 110, and the second spray hole 1203 is gradually blocked. When the large-diameter end of the cone formed by the circumferential outer wall of the spray part 1202 contacts the circumferential inner wall of the opening end 1302 during the screwing process of the spray head 120, the spray head 120 is located in the blocking position, and the second spray hole 1203 is blocked.

[0155] Correspondingly, when the user needs a dispersed and low-pressure water flow, the spray head 120 can also be rotated so that the spray head 120 is rotated toward the side away from the spray pipe 110. During the process of screwing, the large-diameter end of the cone formed by the circumferential outer wall of the spray part 1202 continuously moves toward the side away from the spray pipe 110. When the large-diameter end of the cone formed by the circumferential outer wall of the spray part 1202 does not contact the circumferential inner wall of the opening end 1302, the spray head 120 is in the open position and the second spray hole 1203 is opened.

[0156] See also Fig. 9 As shown, in some embodiments, along the flow direction of the liquid in the spray hole 121:

[0157] The spray hole 121 has a liquid inlet section 1211 and a liquid outlet section 1212 , wherein the liquid inlet section 1211 may be in a contraction structure, and the liquid outlet section 1212 may be in an expansion structure.

[0158] Or, in other embodiments, along the flow direction of the liquid in the spray hole 121:

[0159] The inner diameters of the liquid inlet section 1211 and the liquid outlet section 1212 may be equal.

[0160] Compared with the equal inner diameters of the liquid inlet section 1211 and the liquid outlet section 1212, when the liquid inlet section 1211 presents a contraction structure and the liquid outlet section 1212 presents an expansion structure along the flow direction of the liquid in the spray hole 121, the pressure of the water flow generated by the spray hole 121 can be instantly increased.

[0161] Specifically, along the flow direction of the liquid in the spray hole 121, the liquid inlet section 1211 is in a contraction structure, and the liquid outlet section 1212 is in an expansion structure. Along the flow direction of the liquid in the spray hole 121, the cross-sectional area of ​​the liquid inlet section 1211 gradually decreases, and the cross-sectional area of ​​the liquid outlet section 1212 gradually increases. The cross-sectional areas of the spray hole 121 in the liquid inlet section 1211 and the liquid outlet section 1212 can be formed by the same cross section. The cross section is perpendicular to the length direction of the fixing member 130 (see the W direction).

[0162] It should be understood that, generally, when a liquid flows in a pipe, the flow rate of the liquid is inversely proportional to the cross-sectional area of ​​the pipe.

[0163] Since the spray hole 121 can also be regarded as a kind of pipe, the cross-sectional area of ​​the liquid inlet section 1211 gradually decreases along the flow direction of the liquid in the spray hole 121. Therefore, when the liquid flows in the liquid inlet section 1211, the flow velocity of the liquid increases continuously in the process of flowing in the liquid inlet section 1211. When the flow velocity of the liquid increases to a critical point in the liquid inlet section 1211, the flow velocity will not increase any more. At the critical point, the velocity of the fluid is greater than the speed of sound.

[0164] When the speed of the fluid is greater than the speed of sound, the above-mentioned inverse proportionality between the flow velocity and the cross-sectional area of ​​the liquid is no longer applicable, but just the opposite. The larger the cross-sectional area, the faster the flow velocity of the liquid. Since the cross-sectional area of ​​the liquid outlet section 1212 gradually increases along the flow direction of the liquid in the spray hole 121, when the liquid enters the liquid outlet section 1212, the liquid continues to accelerate and becomes supersonic, so that the flow velocity of the liquid can be instantly increased when the liquid is sprayed out through the spray hole 121. For the spray hole 121, the flow velocity is proportional to the pressure. Therefore, when the flow velocity of the liquid increases instantaneously, the pressure of the liquid also increases instantaneously. At this time, the pressure of the water flow generated by the liquid in the liquid inlet pipeline through the spray hole 121 can be instantly increased, forming a high-pressure water flow, which can effectively rinse the clothes in the inner drum 50 and improve the cleaning effect.

[0165] At the same time, since the cross-sectional area of ​​the liquid outlet section 1212 gradually increases along the flow direction of the liquid in the spray hole 121, the liquid has a larger spraying area when it is sprayed to the inner drum 50 through the liquid outlet section 1212, so that the liquid sprayed to the inner drum 50 through the spray hole 121 can cover a large area and rinse the clothes in the inner drum 50, which can efficiently wash the clothes and improve the cleaning effect.

[0166] See also Fig. 9 As shown, along the flow direction of the liquid in the spray hole 121, the inner diameter of the liquid inlet section 1211 gradually decreases, and the inner diameter of the liquid outlet section 1212 gradually increases, and the inner diameters of the liquid inlet section 1211 and the liquid outlet section 1212 at the opposite ends are equal, so that along the flow direction of the liquid in the spray hole 121, the cross-sectional area of ​​the liquid inlet section 1211 gradually decreases, and the cross-sectional area of ​​the liquid outlet section 1212 gradually increases. In addition, since the inner diameters of the liquid inlet section 1211 and the liquid outlet section 1212 at the opposite ends are equal, the inner diameter of the spray hole 121 can also smoothly transition between the liquid inlet section 1211 and the liquid outlet section 1212, so as to ensure that the liquid can flow to the liquid outlet section 1212 along the predetermined water flow direction. At the same time, since the inner diameters of the liquid inlet section 1211 and the liquid outlet section 1212 at the opposite ends are equal, the spray hole 121 forms a narrow channel between the liquid inlet section 1211 and the liquid outlet section 1212. When the liquid flows to the narrow channel through the liquid inlet section 1211, the flow of the liquid is at the critical point mentioned above.

[0167] See also Fig. 9 As shown, the liquid inlet section 1211 can be directly connected to the liquid outlet section 1212. Alternatively, the spray hole 121 can also have a connecting section, and the liquid inlet section 1211 and the liquid outlet section 1212 are connected in the connecting section. Along the flow direction of the liquid in the spray hole 121, the inner diameters of the connecting section are equal, and the inner diameter of the connecting section is equal to the minimum inner diameter of the liquid inlet section 1211 and the liquid outlet section 1212, so that the hole wall of the spray hole 121 can smoothly transition with the connecting section at the inner diameters of the liquid inlet section 1211 and the liquid outlet section 1212, so as to ensure that the liquid can flow to the liquid outlet section 1212 along the predetermined water flow direction. In addition, by directly connecting the liquid inlet section 1211 with the liquid outlet section 1212, or by setting the connecting section, the structure of the spray hole 121 can be made more diversified to meet the design requirements of different spray heads 120 for the spray hole 121.

[0168] Compared with the setting of the connecting section, when the liquid inlet section 1211 can be directly connected to the liquid outlet section 1212, the pressure of the liquid is instantly increased, the spraying area is increased, and the length of the spray hole 121 in the W direction can be reduced, which is beneficial to reducing the size of the spray head 120 in the W direction and realizing the miniaturization of the spray head 120.

[0169] It should be noted that, in some embodiments, other openings may be provided at other positions of the spray part 1202 , and these openings may be connected to the cavity 1301 of the fixing member 130 . These openings may always be in an open state, and may be opened or closed to further expand the spraying area of ​​the spray assembly 100 .
