[0042] In the related art, when a drum washing machine is in operation, additives enter between the laundry treatment tub and the cabinet along with the cleaning water, resulting in low utilization efficiency of the additives, reducing the cleaning ability of the drum washing machine for laundry. Moreover, the drum washing machine is also provided with a water inlet structure for spraying cleaning water into the laundry treatment tub, which makes the structure of the drum washing machine more complex and increases the production cost of the drum washing machine at the same time.
[0043] Reference will be made below to Figures 1 - 10 describe the nozzle assembly 1 for a laundry treatment device according to an embodiment of the present invention.
[0044] As Figures 1 - 10 shown, the nozzle assembly 1 according to the present invention includes: a component body for being installed in the laundry treatment cavity of the laundry treatment device. A first feeding channel 221 and a second feeding channel 13 are formed on the component body. The first feeding channel 221 is used to communicate with the feeding box 3 to feed additives into the laundry treatment cavity, and the second feeding channel 13 is used to communicate with an external water source to feed washing media into the laundry treatment cavity.
[0045] In some embodiments, the laundry treatment device may be configured as a drum washing machine or the like. The laundry treatment device includes a cabinet, and an installation cavity is formed inside the cabinet for installing the laundry treatment tub 2 and various components. The laundry treatment tub 2 is rotatably arranged in the installation cavity, and the laundry treatment tub 2 is arranged horizontally or at an angle to the horizontal direction. The inside of the laundry treatment tub 2 is provided with a laundry treatment cavity, and laundry is stored in the laundry treatment cavity so that the laundry treatment device can wash the laundry. The front end of the laundry treatment tub 2 is provided with a feeding port communicating with the laundry treatment cavity, and a door body is also connected to the front end of the cabinet. By operating the door body, the feeding port can be opened or closed, so that the laundry can be fed into the laundry treatment cavity through the feeding port. Specifically, the door body is rotatably connected to the cabinet.
[0046] It is understandable that the dosing box 3 is suitable for storing additives. The additives can directly enter the laundry treatment chamber through the first dosing channel 221, and the cleaning water can enter the laundry treatment chamber through the second dosing channel 13. The additives are combined with the washing medium to clean the clothes in the laundry treatment chamber.
[0047] The additives directly enter the laundry treatment chamber through the first dosing channel 221, avoiding the residues of the additives between the door body and the dosing port, that is, avoiding the residues of the additives between the laundry treatment tub 2 and the cabinet, improving the utilization rate of the additives, thus improving the cleaning ability of the laundry treatment device for clothes and enhancing the user experience. Among them, the additives can be liquid detergents and / or solid detergents. The liquid detergents can include detergents, fabric softeners, fungicides, care agents and other common preparations. The solid detergents can include washing powders, liquid detergents, laundry gels and laundry beads, etc.; the washing medium can be cleaning water, etc.
[0048] At the same time, the cleaning water can be sprayed into the laundry treatment chamber through the second dosing channel 13, avoiding the separate setting of the water inlet structure for spraying the cleaning water towards the laundry treatment chamber in the laundry treatment device. Thus, the spray head assembly 1 of the present application can integrate the function of the water inlet structure, making the function of the spray head assembly 1 more abundant. At the same time, the structure of the laundry treatment device can be simplified, reducing the production cost of the laundry treatment device.
[0049] It is worth mentioning that the outlet of the second dosing channel 13 can be arranged towards the door body. Thus, the user can judge whether the laundry treatment device is operating normally by observing whether there is water sprayed towards the door body, enabling the user to more intuitively feel the operating state of the laundry treatment device and enhancing the user experience. At the same time, during the process of the cleaning water sprayed onto the door body flowing towards the laundry treatment chamber, the cleaning water can wash away the foam and / or additives remaining between the door body and the dosing port, improving the utilization rate of the additives, thus improving the cleaning ability for clothes. At the same time, it can avoid the existence of foam and / or additives between the door body and the dosing port after the clothes are washed, enhancing the user experience.
[0050] According to the spray head assembly 1 involved in the present invention, its first dosing channel 221 is used to communicate with the dosing box 3 to dose additives into the laundry treatment chamber, and the second dosing channel 13 is used to communicate with an external water source to dose the washing medium into the laundry treatment chamber. The first dosing channel 221 can directly dose the additives into the laundry treatment chamber, avoiding the residues of the additives between the laundry treatment tub 2 and the cabinet, improving the utilization rate of the additives, thus improving the cleaning ability of the laundry treatment device for clothes. At the same time, the spray head assembly 1 integrates the function of the water inlet structure, making the function of the spray head assembly 1 more abundant, and can simplify the structure of the laundry treatment device, reducing the production cost of the laundry treatment device.
[0051] According to some embodiments of the present invention, as Figures 3 - 5 shown, a first wall 11 and a second wall 12 facing away from each other are formed on the component body. The first wall 11 faces the inside of the laundry treatment chamber and is formed with a first feeding port communicating with the first feeding channel 221; the second wall 12 is formed with a second feeding port communicating with the second feeding channel 13.
[0052] In some embodiments, a first wall 11 and a second wall 12 facing away from each other are formed on the component body. The first wall 11 is arranged facing the inside of the laundry treatment chamber, and the second wall 12 is arranged facing the door body. A first feeding channel 221 and a second feeding channel 13 are formed inside the component body. The first wall 11 is formed with a first feeding port, and the first feeding port communicates with the first feeding channel 221. The second wall 12 is formed with a second feeding port, and the second feeding port communicates with the second feeding channel 13.
[0053] It can be understood that the first feeding port is formed on the first wall 11, and the additive can be directly put into the laundry treatment chamber through the first feeding port, avoiding the residue of the additive between the laundry treatment tub 2 and the box body, improving the utilization rate of the additive, thereby improving the cleaning ability of the laundry treatment device for clothes and enhancing the user experience; the cleaning water can be sprayed onto the door body through the second feeding port, enabling the user to more intuitively feel the operating state of the laundry treatment device, enhancing the user experience. At the same time, spraying the cleaning water towards the door body can wash away the foam and / or additive remaining between the door body and the feeding port, improving the utilization rate of the additive, and thus improving the cleaning ability for clothes.
[0054] It is worth noting that the second feeding channel 13 can be connected to the feeding box 3. At this time, the additive can enter the laundry treatment chamber through the second feeding channel 13; alternatively, the additive can enter the laundry treatment chamber through the first feeding channel 221 and the second feeding channel 13 respectively. Thus, the additive can enter the laundry treatment chamber in different ways through the nozzle assembly 1, making the feeding mode of the additive diversified.
[0055] In some embodiments, the diameter of the first feeding port is D, satisfying 1 mm ≤ D ≤ 2.5 mm. Here, D = 2 mm is preferably selected to ensure that the entire water circuit has a certain pressure under high water pressure. The first feeding channel 221 is provided with a pressure relief valve. The pressure relief valve includes a valve body and a valve core. A valve channel is formed on the valve body, and the valve channel is adapted to communicate with the first feeding channel 221. The valve core is movably arranged in the valve channel and is adapted to move and open the valve channel after the pressure in the first feeding channel 221 exceeds a preset value; a communication channel is formed on the valve body, and the communication channel connects the first feeding channel 221 with the outside.
[0056] Specifically, a valve passage for receiving a valve core is formed on the valve body. One end of the valve passage communicates with the first dosing passage 221, and the other end of the valve passage communicates with the outside. When the pressure in the first dosing passage 221 is below a preset value, the valve core is fixed at the connection between the valve passage and the first dosing passage 221 and closes the valve passage. When the pressure in the first dosing passage 221 exceeds the preset value, the high-pressure gas in the first dosing passage 221 pushes the valve core to move along the extending direction of the valve passage and opens the valve passage, so as to discharge the high-pressure gas in the first dosing passage 221 and prevent the first dosing passage 221 from being damaged due to excessive pressure in the first dosing passage 221.
[0057] Wherein, a communication passage is formed on the valve passage. After the valve core is pushed by the high-pressure gas in the first dosing passage 221, the communication passage connects the first dosing passage 221 with the outside, thereby discharging the high-pressure gas in the first dosing passage 221 and realizing pressure relief for the first dosing passage 221. The communication passage can be arranged on the valve body and spaced from the valve passage. One end of the communication passage communicates with the first dosing passage 221, and the other end of the communication passage communicates with the outside, so as to connect the first dosing passage 221 with the outside through the communication passage. When the pressure in the first dosing passage 221 exceeds the preset value, the high-pressure gas in the first dosing passage 221 can be discharged to the outside through the valve passage and the communication passage, thereby increasing the gas flow area, facilitating the reduction of the gas flow velocity, eliminating the whistling noise generated during gas pressure relief, and improving the user experience.
[0058] Preferably, the pressure relief groove is arranged on the inner wall of the valve passage and on the outer periphery of the valve core. A gap is formed between the bottom wall of the pressure relief groove and the valve core to form a communication passage. Thus, the first dosing passage 221 can be pressure-relieved through the valve passage and the communication passage. The pressure relief groove has a simple structure. After the high-pressure gas in the first dosing passage 221 enters the communication passage, the gas flow area is increased and the gas flow velocity is reduced, thereby eliminating the whistling noise generated by gas discharge and improving the user experience.
[0059] In some embodiments, the second dosing passage 13 is connected to a water pump. The water pump is adapted to pump the cleaning water in the liquid storage chamber to the second dosing passage 13. A check valve is arranged between the second dosing passage 13 and the water pump. The check valve can prevent the cleaning water from flowing back to the water pump and prevent the water pump from leaking or reverse water flow to the liquid storage chamber due to water pressure and cleaning water.
[0060] According to some embodiments of the present invention, such as Figures 2 - 5As shown in the figure, the component body includes: a base housing 10, a connection head 30, and a first seal. A first delivery channel 221 and a second delivery channel 13 are formed inside the base housing 10. A first docking wall is formed on the base housing 10. A transfer inlet of the first delivery channel 221 and a transfer inlet of the second delivery channel 13 are formed on the first docking wall. The connection head 30 is disposed on the base housing 10 and is formed with a transfer channel 31 that communicates with the first delivery channel 221 and the second delivery channel 13 respectively. A second docking wall that abuts against the first docking wall is formed on the connection head 30. A transfer outlet that communicates with the transfer channel 31 is formed on the second docking wall. The first seal is disposed between the first docking wall and the second docking wall and is disposed around the outer periphery of the transfer inlet or the transfer outlet.
[0061] In some embodiments, the base housing 10 can be understood as the basis of the spray head assembly 1, and the connection head 30 can be understood as the transfer structure of the spray head assembly 1. Specifically, a first docking wall is formed on the base housing 10, and a second docking wall is formed on the connection head 30. When the connection head 30 and the base housing 10 are fitted together, the first docking wall and the second docking wall can be mutually attached, improving the stability of the cooperation between the connection head 30 and the base housing 10. A first delivery channel 221 and a second delivery channel 13 are also formed inside the base housing 10. Two transfer channels 31 are formed inside the connection head 30. The first delivery channel 221 communicates with one of the transfer channels 31 so that the spray head assembly 1 can deliver additives into the laundry treatment chamber, and the second delivery channel 13 communicates with the other transfer channel 31 so that the spray head assembly 1 can deliver cleaning water into the laundry treatment chamber.
[0062] A transfer inlet of the first delivery channel 221 and a transfer inlet of the second delivery channel 13 are formed on the first docking wall, and two transfer outlets that communicate with the two transfer channels 31 respectively are formed on the second docking wall. During assembly, the first docking wall and the second docking wall are attached, and the transfer inlet of the first delivery channel 221 and the transfer inlet of the second delivery channel 13 are respectively aligned with the two transfer outlets, realizing the communication between the first delivery channel 221 and the second delivery channel 13 and the two transfer channels 31 respectively. The first seal is configured as two, and the two first seals are respectively arranged corresponding to the first delivery channel 221 and the second delivery channel 13. Thus, the first seal can be disposed around the transfer outlet or the transfer inlet, and the first seal is located between the first docking wall and the second docking wall. During assembly, the first seal is disposed around the transfer outlet or the transfer inlet, making the sealing effect better when the transfer outlet and the transfer inlet are fitted together. At the same time, the first docking wall and the second docking wall can limit the first seal, further improving the sealing effect of the first seal. Compared with an additional sealing structure, the first seal of the present application is disposed inside the spray head assembly 1, with a better sealing effect, a simple structure, low cost, and a wider application range.
[0063] It can be understood that the first seal is a sealing structure in the nozzle assembly 1. The first seal can prevent liquid leakage at the joint between the transfer inlet and the transfer outlet, improving the sealing effect of the nozzle assembly 1. The component body of the present application further includes a second seal, which is disposed around the outer periphery of the two first seals. It can be understood that at least part of the two first seals is located in the plane on the first docking wall, and the second seal can connect the two first seals and seal the gap between the first seal and the first docking wall, further improving the sealing effect of the nozzle assembly 1. By providing the first seal and the second seal in the nozzle assembly 1 of the present application, the first seal is disposed around the outer periphery of the transfer inlet, improving the sealing effect when the transfer channel is connected to the fluid channel, and the second seal is disposed on the outer periphery of the first seal, improving the sealing effect between the first seal and the first docking wall.
[0064] In some embodiments, as Figures 9 - 10 shown, the connector 30 is connected to the dosing cartridge 3 and an external water source through a conduit. The laundry treatment device is provided with a door 4, and the door 4 can be configured as a part of the cabinet. The nozzle assembly 1 is mounted on the door 4 through a fixing bracket 5. Specifically, the fixing bracket 5 is fixedly connected to the door 4. The fixing bracket 5 is formed with a first fixing portion 41 and a second fixing portion 42. The first fixing portion 41 is adapted to cooperate with the connector 30 to fix the nozzle assembly 1 to the door 4, reducing the gap between the nozzle assembly 1 and the door 4. The second fixing portion 42 is adapted to fix the conduit to reduce the influence of the conduit on the nozzle assembly 1, and at the same time, the arrangement of the conduit can be made neater. Preferably, the first fixing portion 41 and the second fixing portion 42 are respectively configured as elastic buckles, which is convenient for the assembly of the laundry treatment device and improves the production efficiency of the laundry treatment device. Further, the front section of the elastic buckle is designed as an inclined surface, and the inclined surface can guide the connector 30 or the conduit, making the installation of the connector 30 and the conduit more convenient.
[0065] According to some embodiments of the present invention, as Figures 2 - 5 shown, the component body is formed with a first dosing channel 221 communicating with the laundry treatment chamber, a second dosing channel 13, and a residual water chamber 14 adapted to store residual water.
[0066] It can be understood that when the first dispensing channel 221 is blocked by clothes or impurities, the additives remaining in the first dispensing channel 221 can flow into the residual water chamber 14 for storage; during the operation of the clothes treatment device, the additives leaking out of the transfer chamber can also be stored in the residual water chamber 14; at the same time, the washing water splashed from the clothes treatment chamber into the component body can also be stored in the residual water chamber 14. Thus, by providing the residual water chamber 14 in the component body, the washing water and / or additives flowing into the spray head assembly 1 from the dispensing channel, the transfer chamber and the clothes treatment chamber can be cached, preventing the washing water and / or additives from flowing into other electrical components, and improving the stability and safety of the clothes treatment device during operation.
[0067] According to some embodiments of the present invention, as Figure 5 shown, a residual water hole 15 is formed on the component body to communicate the residual water chamber 14 with the clothes treatment chamber.
[0068] In some embodiments, a residual water hole 15 is further provided on the component body. The residual water hole 15 connects the residual water chamber 14 and the clothes treatment chamber. The washing water or additives stored in the residual water chamber 14 from the clothes treatment chamber, the washing chamber and the dispensing channel can flow back into the clothes treatment chamber through the residual water hole 15, improving the utilization rate of the additives and thus enhancing the cleaning ability of the clothes treatment device for clothes.
[0069] In addition, the provision of the residual water hole 15 can also prevent the liquid stored in the residual water chamber 14 from being excessive, thus preventing the liquid in the residual water chamber 14 from overflowing onto other electrical components, and improving the stability and reliability of the clothes treatment device during operation.
[0070] According to some embodiments of the present invention, as Figures 2 - 8 shown, an air suction channel 23 is formed on the component body to communicate the first dispensing channel 221 with the residual water chamber 14.
[0071] It can be understood that the residual water chamber 14 is communicated with the clothes treatment chamber through the residual water hole 15. Thus, the air suction channel 23 can introduce the gas in the clothes treatment chamber into the first dispensing channel 221, thereby increasing the gas content of the washing water in the first dispensing channel 221, further increasing the number of bubbles formed by the dispensed washing water, increasing the contact area between the washing water and the clothes, improving the utilization rate of the washing water, and thus enhancing the washing effect of the clothes.
[0072] At the same time, by forming bubbles with the dispensed washing water, a large number of bubbles can generate more foam under impact. The cleaning components are relatively dispersed, and the foam can cover a larger clothes area, thereby increasing the contact area between the washing water and the clothes, improving the washing effect of the clothes, and only a small amount of cleaning water can be introduced into the clothes treatment chamber to wet the clothes. Compared with the conventional water washing method of introducing a large amount of cleaning water into the clothes treatment chamber, the use of cleaning water can be effectively reduced.
[0073] According to some embodiments of the present invention, as Figures 4 - 8 shown, the first delivery channel 221 includes a first lumen segment 2211, a second lumen segment 2212, and a third lumen segment 2213 that are connected in sequence. Along the direction of the first lumen segment 2211 towards the second lumen segment 2212, the flow area of the first lumen segment 2211 gradually decreases. Along the direction of the second lumen segment 2212 towards the third lumen segment 2213, the flow area of the third lumen segment 2213 gradually increases.
[0074] It can be understood that by arranging the first lumen segment 2211, the second lumen segment 2212, and the third lumen segment 2213 in the above structure, a structure similar to a Venturi tube is formed inside the first delivery channel 221, and the Venturi effect can be correspondingly generated. The Venturi effect refers to that when a fluid passes through a narrow part of a pipeline, it will cause the fluid velocity at that place to increase, and at the same time the static pressure decreases. Since the second lumen segment 2212 is narrower than the first lumen segment 2211 and the third lumen segment 2213, by connecting the suction channel 23 to the second lumen segment 2212, when there is fluid flowing in the first delivery channel 221, such as when washing water flows in the first delivery channel 221, under the action of the Venturi effect in the first delivery channel 221, the gas outside the first delivery channel 221 can enter the first delivery channel 221, thereby increasing the gas content in the washing water in the first delivery channel 221, and further increasing the number of bubbles formed by the washing water ejected from the outlet of the first delivery channel 221, increasing the contact area between the washing water and the clothes, and thus improving the washing effect of the clothes.
[0075] According to some embodiments of the present invention, as Figures 7 - 8 shown, the suction channel 23 connects the second lumen segment 2212 to the residual water chamber 14. It can be understood that when the third lumen segment 2213 is blocked, the detergent in the first delivery channel 221 can flow into the suction channel 23 from the second lumen segment 2212, and then flow into the residual water chamber 14 through the suction channel 23, effectively preventing the detergent in the first delivery channel 221 from flowing back into the delivery box 3, and at the same time avoiding the additive staying between the delivery box 3 and the third lumen segment 2213, thereby avoiding the leakage of the additive from the connection between the delivery box 3 and the component body, and ensuring the stability and reliability of the clothes treatment device during operation.
[0076] According to some embodiments of the present invention, as Figure 4As shown, the component body includes: a base housing 10 and a nozzle portion 20. A first wall 11 and a second wall 12 are formed on the base housing 10, and a channel cavity 16 and a second delivery channel 13 are formed inside the base housing 10. The outlet of the channel cavity 16 is provided on the first wall 11, and at least a part of the nozzle portion 20 is received in the channel cavity 16 and a first delivery channel 221 is formed in the nozzle portion 20.
[0077] In some embodiments, a first wall 11 and a second wall 12 that face away from each other are formed on the base housing 10. A channel cavity 16 and a second delivery channel 13 are formed inside the base housing 10. The outlet of the channel cavity 16 is formed on the first wall 11, and the outlet of the second delivery channel 13 is formed on the second wall 12. A first delivery channel 221 is formed in the nozzle portion 20. At least a part of the nozzle portion 20 is received in the channel cavity 16 and the first delivery channel 221 communicates with the channel cavity 16. It can be understood that after the additive is mixed with the clean water to form washing water, the washing water enters the laundry treatment cavity after passing through the first delivery channel 221 in sequence. The first delivery channel 221 in the nozzle portion 20 can make the washing water enter the laundry treatment cavity in a foamy state.
[0078] Thus, by forming the first delivery channel 221 in the nozzle portion 20 and receiving at least a part of the nozzle portion 20 in the channel cavity 16, when the first delivery channel 221 is blocked, the user can directly disassemble the nozzle portion 20 to dredge the first delivery channel 221, avoiding disassembling the entire component body, simplifying the repair process of the spray head assembly 1, and improving the repair efficiency of the spray head assembly 1. Similarly, when the nozzle portion 20 or the base housing 10 is damaged and needs to be replaced, only the corresponding damaged component needs to be replaced, avoiding replacing the entire spray head assembly 1, and reducing the repair cost of the spray head assembly 1.
[0079] According to some embodiments of the present invention, as Figures 7 - 8 shown, the nozzle portion 20 includes: an upper connection section 21 and a lower connection section 22. The upper connection section 21 is received in the channel cavity 16. An upper connection channel 211 is formed in the upper connection section 21. The upper connection channel 211 is adapted to communicate with the delivery box 3. The lower connection section 22 is provided on the first wall 11. The lower connection section 22 is connected to the upper connection section 21 and a first lumen section 2211, a second lumen section 2212, and a third lumen section 2213 are formed in the lower connection section 22.
[0080] It can be understood that the nozzle part 20 includes an upper connecting section 21 and a lower connecting section 22. The upper connecting section 21 and the lower connecting section 22 are respectively formed and then assembled to form the nozzle part 20, which simplifies the forming process of the nozzle part 20, improves the production efficiency of the nozzle part 20, and thus improves the production efficiency of the spray head assembly 1. It is worth mentioning that the first lumen section 2211 communicates with the upper connecting channel 211. The additive in the dosing box 3 is mixed with the cleaning water to form washing water. The washing water sequentially passes through the upper connecting channel 211, the first lumen section 2211, the second lumen section 2212, and the third lumen section 2213 and then enters the laundry treatment chamber in a foamy state, increasing the contact area between the washing water and the laundry, and thus improving the washing effect of the laundry.
[0081] According to some embodiments of the present invention, the upper connecting section 21 and the lower connecting section 22 are respectively configured as metal parts. It can be understood that the nozzle part 20 includes an upper connecting section 21 and a lower connecting section 22, and both the upper connecting section 21 and the lower connecting section 22 are configured as metal parts. The metal parts have the characteristics of high strength, wear resistance, and corrosion resistance. Thus, through the above settings, the service life of the nozzle part 20 can be extended, the use cost of the laundry treatment equipment can be reduced. At the same time, the metal parts have good plasticity. Thus, the upper connecting section 21 and the lower connecting section 22 being respectively configured as metal parts can improve the production efficiency of the nozzle part 20, and thus improve the production efficiency of the spray head assembly 1.
[0082] In some embodiments, the upper connecting section 21 is provided with a flow disturbing member located in the upper connecting channel 211. It can be understood that the flow disturbing member can make the fluid flowing through the flow disturbing member in the upper connecting channel 211 have a component velocity along the circumferential direction of the upper connecting channel 211. By providing a flow disturbing member in the upper connecting channel 211, the washing water flowing through the flow disturbing member in the upper connecting channel 211 has a component velocity along the circumferential direction of the upper connecting channel 211. When the washing water flows out through the upper connecting channel 211, the component velocity of the washing water along the circumferential direction of the upper connecting channel 211 can increase the spraying angle of the washing water, thereby increasing the spraying area when the washing water enters the laundry treatment chamber, further increasing the contact area between the washing water and the laundry, increasing the utilization rate of the washing water, and improving the washing effect of the laundry.
[0083] Specifically, during the flow of the washing water in the upper connecting channel 211, first, under the action of the flow disturbing member, it forms a component velocity along the circumferential direction of the upper connecting channel 211, and then through the air supplementing effect of the air intake channel 23, the air content in the washing water is increased. When the washing water is sprayed into the laundry treatment chamber, the washing water can diffuse the spraying angle along the circumferential direction of the upper connecting channel 211 and at the same time form a large number of bubble structures, thereby effectively increasing the contact area between the washing water and the laundry, increasing the utilization rate of the washing water, and improving the washing effect of the laundry.
[0084] In some embodiments, a plurality of second delivery channels 13 are formed on the base housing 10, and cleaning water is sprayed toward the door body through the plurality of second delivery channels 13. Among the plurality of second delivery channels 13, the outlets of some of the second delivery channels 13 extend radially, and the outlets of the other part of the second delivery channels 13 extend circumferentially. Thus, the cleaning water can be sprayed toward the door body along the radial direction and the circumferential direction respectively through the plurality of second delivery channels 13, increasing the spraying area of the cleaning water on the door body, and thereby enhancing the cleaning ability of the door body.
[0085] The laundry treatment device according to the present invention will be briefly described below.
[0086] The laundry treatment device according to the present invention is provided with the spray head assembly 1 of the above embodiment. Since the laundry treatment device according to the present invention is provided with the spray head assembly 1 described in any one of the above embodiments, the laundry treatment device has a strong cleaning ability for clothes.
[0087] In summary, for the spray head assembly 1 according to the present invention, its first delivery channel 221 is used to communicate with the delivery box 3 to deliver additives into the laundry treatment chamber, and the second delivery channel 13 is used to communicate with an external water source to deliver a washing medium into the laundry treatment chamber. The first delivery channel 221 can directly deliver the additives into the laundry treatment chamber, avoiding the residues of the additives between the laundry treatment tub 2 and the cabinet, improving the utilization rate of the additives. At the same time, the spray head assembly 1 integrates the function of the water inlet structure, making the function of the spray head assembly 1 more abundant, and can simplify the structure of the laundry treatment device, reducing the production cost of the laundry treatment device; the first delivery port and the second delivery port are respectively formed on the first wall 11 and the second wall 12, and the first wall 11 and the second wall 12 face away from each other, enabling the cleaning water to be sprayed toward the door body through the second delivery port. During the process of the cleaning water flowing toward the laundry chamber after being sprayed onto the door body, the cleaning water can wash away the foam and / or additives remaining between the door body and the delivery port, improving the utilization rate of the additives, thereby enhancing the cleaning ability for clothes and improving the user experience; the seal is disposed between the first docking wall and the second docking wall and is circumferentially disposed around the transfer inlet or the transfer outlet, improving the sealing performance of the spray head assembly 1; a residual water chamber 14 is formed inside the component body. The residual water chamber 14 can buffer the washing water and / or additives flowing into the spray head assembly 1 from the delivery channels, the transfer chamber, and the laundry treatment chamber, preventing the washing water and / or additives from flowing into other electrical components, and improving the stability and safety of the laundry treatment device during operation.
