[0040] In the related art, the spray head assembly in the laundry treatment device generally discharges towards the laundry treatment cavity. Since the discharging direction of the spray head assembly is single, a larger area cannot be covered.

[0041] Next, refer to Figures 1-10 Describe the spray head assembly 1 for a laundry treatment device according to an embodiment of the present invention.

[0042] As shown Figures 1-10 In the nozzle assembly 1 according to the present invention, as shown, it includes: a component body, on which a first wall 11 and a second wall 12 facing away from each other are formed. A first discharge channel 221 and a second discharge channel 13 are respectively formed on the component body; wherein the outlet of the first discharge channel 221 is provided on the first wall 11 and is adapted to face the laundry treatment chamber, and the outlet of the second discharge channel 13 is provided on the second wall 12 and is adapted to face away from the laundry treatment chamber; in some embodiments, the component body is disposed in the laundry treatment chamber of the laundry treatment device.

[0043] 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, inside which an installation cavity is formed for installing the laundry treatment tub 2 and various components. The laundry treatment tub 2 is rotatably disposed in the installation cavity, and the laundry treatment tub 2 is disposed horizontally or at an angle to the horizontal direction. The interior of the laundry treatment tub 2 is provided with a laundry treatment chamber, and laundry is stored in the laundry treatment chamber 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 chamber, and the front end of the cabinet is further connected with a door body. By operating the door body, the feeding port can be opened or closed, so that the laundry can be fed into the laundry treatment chamber through the feeding port. Specifically, the door body is rotatably connected to the cabinet.

[0044] A component body is disposed in the laundry treatment chamber. 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 laundry treatment chamber, and the second wall 12 faces away from the laundry treatment chamber, that is, the second wall 12 can face the door body. A first discharge channel 221 and a second discharge channel 13 are formed in the component body. The outlet of the first discharge channel 221 is formed on the first wall 11 and faces the laundry treatment chamber, and the outlet of the second discharge channel 13 is formed on the second wall 12 and faces the door body.

[0045] It is understandable that the liquid detergent and / or solid detergent are combined with the cleaning water to wash the clothes in the clothes treatment cavity. The liquid detergent and / or solid detergent can be directly put into the clothes treatment cavity through the first feeding channel 221, avoiding the residue of the liquid detergent and / or solid detergent between the door body and the feeding port, improving the utilization rate of the liquid detergent and / or solid detergent, thus improving the cleaning ability of the clothes treatment device for clothes and enhancing the user experience. Among them, the liquid detergent may include detergents, fabric softeners, bactericides, care agents and other common preparations, and the solid detergent may include washing powder, liquid laundry detergent, laundry gel and laundry beads, etc. Of course, it can also be that the liquid detergent and / or solid detergent enter the clothes treatment cavity through the second feeding channel 13, or the liquid detergent and / or solid detergent enter the clothes treatment cavity through the first feeding channel 221 and the second feeding channel 13 respectively. Thus, the liquid detergent and / or solid detergent can enter the clothes treatment cavity in different ways through the spray head assembly 1, making the feeding methods of the liquid detergent and / or solid detergent diversified.

[0046] In some other embodiments, the cleaning water can be sprayed onto the door body through the second feeding channel 13. Thus, the user can judge whether the clothes 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 clothes 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 clothes treatment cavity, the cleaning water can wash away the foam, liquid detergent and / or solid detergent remaining between the door body and the feeding port, improving the utilization rate of the liquid detergent and / or solid detergent, thus improving the cleaning ability for clothes, and at the same time, it can avoid the existence of foam, liquid detergent and / or solid detergent between the door body and the feeding port after the clothes are washed, enhancing the user experience.

[0047] According to the spray head assembly 1 involved in the present invention, the outlet of the first feeding channel 221 is arranged on the first wall 11 and is adapted to face the clothes treatment cavity, while the outlet of the second feeding channel 13 is arranged on the second wall 12 and is adapted to face away from the clothes treatment cavity, enabling the spray head assembly 1 to have the function of spraying the liquid detergent and / or solid detergent towards the clothes treatment cavity and the function of spraying the cleaning water towards the door body. The functions of the spray head assembly 1 are more abundant, and the liquid detergent and / or solid detergent can enter the clothes treatment cavity in different ways through the spray head assembly 1, making the feeding methods of the liquid detergent and / or solid detergent diversified. At the same time, the cleaning water can be sprayed onto the door body through the second feeding channel 13, enabling the user to more intuitively feel the operating state of the clothes treatment device. And at the same time, during the process of the cleaning water sprayed onto the door body flowing towards the clothes treatment cavity, the cleaning water can wash away the foam, liquid detergent and / or solid detergent remaining between the door body and the feeding port, improving the utilization rate of the liquid detergent and / or solid detergent, thus improving the cleaning ability for clothes and enhancing the user experience.

[0048] According to some embodiments of the present invention, as Figures 3-5 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 and a second delivery channel 13 are formed inside the base housing 10. The outlet of the channel cavity is provided on the first wall 11, and at least a part of the nozzle portion 20 is received in the channel cavity and a first delivery channel 221 is formed in the nozzle portion 20.

[0049] 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 and a second delivery channel 13 are formed inside the base housing 10. The outlet of the channel cavity 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 and the first delivery channel 221 communicates with the channel cavity. It can be understood that the liquid detergent and / or solid detergent are mixed with the cleaning water to form washing water, and 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.

[0050] 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, 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 maintenance process of the spray head assembly 1, and improving the maintenance 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 maintenance cost of the spray head assembly 1.

[0051] According to some embodiments of the present invention, as Figure 4 and Figure 9 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.

[0052] It can be understood that by arranging the first lumen segment 2211, the second lumen segment 2212, and the third lumen segment 2213 according to the above structure, a structure similar to a Venturi tube is formed inside the first dispensing channel 221, and the Venturi effect can be correspondingly generated. The Venturi effect means that when a fluid passes through a narrow part of a pipe, the velocity of the fluid at that place will increase, and at the same time, the static pressure will decrease. 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 25 to the second lumen segment 2212, when there is a fluid flowing in the first dispensing channel 221, such as washing water flowing in the first dispensing channel 221, under the action of the Venturi effect in the first dispensing channel 221, the gas outside the first dispensing channel 221 can enter the first dispensing channel 221, thereby increasing the gas content in the washing water in the first dispensing channel 221, and further increasing the number of bubbles formed by the washing water ejected from the outlet of the first dispensing channel 221, increasing the contact area between the washing water and the clothes, and thus improving the washing effect of the clothes.

[0053] According to some embodiments of the present invention, such as Figure 4 and Figure 9 shown, an air suction channel 25 communicating the second lumen segment 2212 with the outside is formed on the nozzle portion 20.

[0054] It can be understood that the air suction channel 25 is adapted to introduce the gas outside the nozzle assembly 1 into the first dispensing channel 221, thereby increasing the gas content in the washing water in the first dispensing channel 221, and 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.

[0055] At the same time, by forming bubbles in 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 area of the clothes, 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.

[0056] According to some embodiments of the present invention, such as Figures 6-9As shown, the nozzle part 20 includes an upper connection section 21 and a lower connection section 22. The upper connection section 21 is received in the channel cavity. An upper connection channel 211 is formed in the upper connection section 21, and the upper connection channel 211 is adapted to communicate with the dispensing box. The lower connection section 22 is disposed 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. It can be understood that the nozzle part 20 includes the upper connection section 21 and the lower connection section 22. The upper connection section 21 and the lower connection section 22 are respectively formed and 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 connection channel 211. The liquid detergent and / or solid detergent in the dispensing box are mixed with the cleaning water to form washing water. The washing water sequentially passes through the upper connection channel 211, the first lumen section 2211, the second lumen section 2212, and the third lumen section 2213 and then enters the laundry treatment cavity in a foamy state, increasing the contact area between the washing water and the laundry, and thus improving the washing effect of the laundry.

[0057] According to some embodiments of the present invention, as Figures 7-8 shown, the upper connection section 21 is provided with a turbulator 23 located in the upper connection channel 211.

[0058] It can be understood that the turbulator 23 can cause the fluid flowing through the turbulator 23 in the upper connection channel 211 to have a component velocity in the circumferential direction of the upper connection channel 211. By providing the turbulator 23 in the upper connection channel 211, the washing water flowing through the turbulator 23 in the upper connection channel 211 has a component velocity in the circumferential direction of the upper connection channel 211. When the washing water flows out through the upper connection channel 211, the component velocity of the washing water in the circumferential direction of the upper connection channel 211 can increase the spraying angle of the washing water, thereby increasing the spraying area when the washing water enters the laundry treatment cavity, 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.

[0059] Specifically, during the flow of the washing water in the upper connection channel 211, first, under the action of the turbulator 23, it forms a component velocity in the circumferential direction of the upper connection channel 211, and then through the air supplement function of the air intake channel 25, the air content in the washing water is increased. When the washing water is sprayed into the laundry treatment cavity, the washing water can diffuse the spraying angle in the circumferential direction of the upper connection 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.

[0060] According to some embodiments of the present invention, as Figures 3-10As shown, a groove is formed at the end of the lower connecting section 22 facing the laundry treatment chamber, and an outlet of the first feeding channel 221 is provided on the bottom wall of the groove. It can be understood that when there are a large number of clothes in the laundry treatment chamber, the clothes will contact the end of the lower connecting section 22 facing the laundry treatment chamber. Thus, by providing a groove at the end of the lower connecting section 22 facing the laundry treatment chamber and arranging the outlet of the first feeding channel 221 on the bottom wall of the groove, it is possible to prevent the clothes from blocking the outlet of the first feeding channel 221, so that the washing water can be smoothly sprayed into the laundry treatment chamber. At the same time, when the laundry treatment tub 2 rotates and washes the clothes, the washing water may splash onto the nozzle assembly 1, and the groove can buffer the washing water splashed to the outlet of the first feeding channel 221, preventing the washing water from flowing back into the nozzle assembly 1 through the first feeding channel 221.

[0061] According to some embodiments of the present invention, as Figures 3-10 shown, a circular protrusion 24 surrounding the outlet of the first feeding channel 221 is formed at the end of the lower connecting section 22, and a groove is defined within the circular protrusion 24. It can be understood that when there are a large number of clothes in the laundry treatment chamber, the circular protrusion 24 can contact the clothes and is adapted to prevent the clothes from blocking the outlet of the first feeding channel 221, so that the washing water can be smoothly sprayed into the laundry treatment chamber.

[0062] According to some embodiments of the present invention, as Figures 9-10 shown, the circular protrusion 24 includes: a lower arc portion 242 and an upper arc portion 241. The lower arc portion 242 is disposed on the outer periphery of the lower edge of the outlet of the first feeding channel 221, and the upper arc portion 241 is disposed on the outer periphery of the upper edge of the outlet of the first feeding channel 221. The upper arc portion 241 is connected to the lower arc portion 242 to enclose the groove; wherein the thickness of the lower arc portion 242 is less than the thickness of the upper arc portion 241.

[0063] In some embodiments, the upper arc portion 241 is disposed around the outer periphery of the upper edge of the outlet of the first dispensing channel 221, and the lower arc portion 242 is disposed around the outer periphery of the lower edge of the outlet of the first dispensing channel 221. The two ends of the upper arc portion 241 in the circumferential direction of the outlet of the first dispensing channel 221 are respectively connected to the two ends of the lower arc portion 242 in the circumferential direction of the outlet of the first dispensing channel 221. The thickness of the upper arc portion 241 is larger than that of the lower arc portion 242. It can be understood that the lower arc portion 242 is closer to the center of the laundry treatment chamber than the upper arc portion 241, so that the lower arc portion 242 is more likely to contact the laundry. Therefore, by making the arc of the lower arc portion 242 smaller, the contact area between the lower arc portion 242 and the laundry can be reduced, thereby reducing the damage to the laundry; the upper arc portion 241 is adapted to abut against the base housing 10. Therefore, by making the thickness of the upper arc portion 241 larger, the contact area between the upper arc portion 241 and the base housing 10 can be increased, thereby improving the connection stability between the upper arc portion 241 and the base housing 10, and further improving the connection stability between the nozzle portion 20 and the base housing 10.

[0064] According to some embodiments of the present invention, as Figure 2 shown, a plurality of second dispensing channels 13 are formed on the base housing 10. The outlet of one of the second dispensing channels 13 sprays towards the door body in the radial direction, and the outlet of another second dispensing channel 13 sprays towards the door body in the circumferential direction.

[0065] In some embodiments, a plurality of second dispensing channels 13 are formed on the base housing 10, and the cleaning water sprays towards the door body through the plurality of second dispensing channels 13.

[0068] The clothing treatment device according to the present invention is provided with the spray head assembly 1 of the above embodiment. Since the clothing treatment device according to the present invention is provided with the spray head assembly 1 described in any one of the above embodiments, the cleaning ability of the clothing treatment device for clothing is better.

[0069] In summary, according to the spray head assembly 1 involved in the present invention, the outlet of the first dispensing channel 221 is arranged on the first wall 11 and is adapted to face the laundry treatment cavity. At the same time, the outlet of the second dispensing channel 13 is arranged on the second wall 12 and is adapted to face away from the laundry treatment cavity, so that the spray head assembly 1 has the function of spraying liquid detergent and / or solid detergent towards the laundry treatment cavity and the function of spraying cleaning water towards the door body. The functions of the spray head assembly 1 are more abundant. At the same time, during the process of the cleaning water sprayed onto the door body flowing towards the laundry treatment cavity, the cleaning water can wash away the foam, liquid detergent and / or solid detergent remaining between the door body and the dispensing port, improving the utilization rate of the liquid detergent and / or solid detergent, thereby improving the cleaning ability of the laundry and enhancing the user experience; the first lumen segment 2211, the second lumen segment 2212 and the third lumen segment 2213 are connected in sequence, and in the direction of the first lumen segment 2211 towards the third lumen segment 2213, the flow area of the first lumen segment 2211 gradually decreases, and the flow area of the third lumen segment 2213 gradually increases, so that a structure similar to a Venturi tube is formed inside the first dispensing channel 221 and the Venturi effect can be correspondingly generated, increasing the number of bubbles formed by the washing water ejected from the outlet of the first dispensing channel 221, increasing the contact area between the washing water and the laundry, and thus improving the washing effect of the laundry; the upper connecting segment 21 is provided with a flow disturbing member 23 located in the upper connecting channel 211. The flow disturbing member 23 can make the washing water have a circumferential component velocity along the upper connecting channel 211, thereby increasing the spraying angle of the washing water, further increasing the spraying area when the washing water enters the laundry treatment cavity, 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; the upper arc portion 241 and the lower arc portion 242 are connected to form a groove surrounding the outlet of the first dispensing channel 221. The groove can cache the washing water and prevent the washing water from flowing back into the spray head assembly 1 through the first dispensing channel 221; the thickness of the lower arc portion 242 being less than the thickness of the upper arc portion 241 can reduce the contact area between the lower arc portion 242 and the laundry, thereby reducing the damage to the laundry; the upper connecting segment 21 and the lower connecting segment 22 are respectively constructed as metal parts, extending the service life of the nozzle portion 20. At the same time, the surfaces of the upper arc portion 241 and the lower arc portion 242 can be made smoother, reducing the wear of the upper arc portion 241 and the lower arc portion 242 on the laundry.
