Description

Technical Field

[0001] The present application relates to the technical field of clothing treatment equipment, and in particular to a nozzle assembly and a clothing treatment equipment. Background Art

[0002] In the field of existing washing machine technology, the atomized washing technology, as an innovative washing method, atomizes the detergent into tiny bubbles through high-pressure water flow, and then penetrates into the clothing fibers to achieve a more thorough and efficient cleaning effect. However, this technology faces a significant technical problem in practical applications: due to the huge pressure generated during the high-pressure atomization of the water flow, the existing washing machine designs often need to be provided with a dedicated pressure relief port to balance the system pressure and prevent equipment damage (such as causing the water box to burst, leak or performance degradation, etc.). However, this design compromise directly causes some of the atomized laundry detergent to flow back through the pressure relief port under high pressure to the space between the detergent box and the inner and outer barrels, rather than directly acting on the clothes. This not only weakens the penetration and peeling ability of the atomized bubbles on the clothing stains, resulting in a decrease in washing efficiency and effect, but also causes waste of the detergent, reduces the utilization rate of the detergent, increases the user's washing cost.

[0044] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0045] Reference below Figures 1-6 A spray head assembly 100 and a laundry treating apparatus 1000 according to an embodiment of the present application are described.

[0046] like Figures 1-5 As shown, according to the nozzle assembly 100 of the first aspect embodiment of the present application, the nozzle assembly 100 includes: a component body, the component body is used to be installed in the clothing processing chamber of the clothing processing device 1000, and a first delivery channel 1a is formed on the component body. The first delivery channel 1a is used to communicate with the delivery box 200 to deliver additives into the clothing processing chamber; wherein a pressure relief channel 1d is formed on the component body, one end of the pressure relief channel 1d is connected to the first delivery channel 1a, and the other end is connected to the clothing processing chamber.

[0047] In some embodiments, the clothing processing device 1000 can be configured as a drum washing machine, etc. The clothing processing device 1000 includes a box body, and a mounting cavity is formed inside the box body, and the mounting cavity is used to install a clothing processing barrel and various components. The clothing processing barrel can be rotatably arranged in the mounting cavity, and the clothing processing barrel is arranged in the horizontal direction or at an angle to the horizontal direction. A clothing processing cavity is arranged inside the clothing processing barrel, and clothing is stored in the clothing processing cavity so that the clothing processing device 1000 can wash the clothing. The front end of the clothing processing barrel is provided with a delivery port connected to the clothing processing cavity, and the front end of the box body is also connected with a door body. By operating the door body, the delivery port can be opened or closed, so that the clothing can be delivered into the clothing processing cavity through the delivery port. The front end of the box body is also provided with a door seal 300, and the door seal 300 can be constructed as a part of the box body. The nozzle assembly 100 can be installed on the door seal 300 through a fixing bracket 400.

[0048] It can be understood that the dispensing box 200 is adapted to store additives. The additives can directly enter the laundry treatment chamber through the first dispensing channel 1a. The additives cooperate with the washing medium to clean the laundry in the laundry treatment chamber. The cooperation between the additives and the washing medium here can be understood as that the additives need to form atomized bubbles under the action of water flow. Specifically, the atomized bubbles can be achieved by an external water source flowing through the dispensing box 200 and mixing with the additives. The additives directly enter the laundry treatment chamber through the first dispensing channel 1a, avoiding the residue of the additives between the door body and the dispensing port, that is, avoiding the residue of the additives between the laundry treatment tub and the cabinet, improving the utilization rate of the additives, thereby improving the cleaning ability of the laundry treatment device 1000 for the laundry 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, bactericides, care agents and other common preparations. The solid detergents can include washing powder, laundry gel and laundry beads, etc.; the washing medium can be clean water, etc.

[0049] It should be noted that a pressure relief channel 1d is also formed on the component body of the present application. The two ends of the pressure relief channel 1d are respectively communicated with the first dispensing channel 1a and the laundry treatment chamber. When the washing water formed by the atomization of the additives and the washing medium flows into the first dispensing channel 1a, a part of the washing water can continue to flow into the laundry treatment chamber along the first dispensing channel 1a, and the other part of the washing water can be diverted into the pressure relief channel 1d and flow into the laundry treatment chamber along the pressure relief channel 1d. Thus, through the diversion of the pressure relief channel 1d, the pressure in the first dispensing channel 1a can be released, preventing system damage or additive leakage caused by excessive pressure during the dispensing process, and further eliminating the need for an additional pressure relief port.

[0050] According to the spray head assembly 100 of the present application, by providing a pressure relief channel 1d communicated with the first dispensing channel 1a and the laundry treatment chamber, the diversion and pressure relief can be realized to reduce the pressure in the first dispensing channel 1a, protecting the device from high-pressure damage, thereby eliminating the need for an additional pressure relief port. In this way, it can be avoided that the washing medium flows back from the pressure relief port to the space between the detergent box and the inner and outer tubs of the laundry treatment device 1000, enabling the washing medium to directly act on the laundry completely, further improving the atomized bubble effect of the detergent, increasing the utilization rate of the detergent, enhancing the laundry washing effect and efficiency, and saving the washing cost.

[0051] In addition, in some specific embodiments of the present application, a second dosing channel 1b is further formed on the component body. The second dosing channel 1b is used to communicate with an external water source to dose washing water into the laundry treatment chamber. It can be understood that the cleaning water can be sprayed into the laundry treatment chamber through the second dosing channel 1b, avoiding the need for the laundry treatment device 1000 to separately provide a water inlet structure for spraying cleaning water towards the laundry treatment chamber. Thus, the nozzle assembly 100 can integrate the function of the water inlet structure, with richer functions, and at the same time, the structure of the laundry treatment device 1000 can be simplified, reducing the production cost of the laundry treatment device 1000.

[0052] As Figure 2 and Figure 3 shown, according to some embodiments of the present application, the component body includes: a base housing 1 and a connection head 2.

[0053] Among them, a first dosing channel 1a is formed inside the base housing 1, a first docking wall is formed on the base housing 1, and a transfer inlet 1c of the first dosing channel 1a is formed on the first docking wall; the connection head 2 is disposed on the base housing 1 and forms a transfer channel 2a communicating with the first dosing channel 1a. A second docking wall that abuts against the first docking wall is formed on the connection head 2, and a transfer outlet 2b communicating with the transfer channel 2a is formed on the second docking wall; a pressure relief channel 1d communicating with the laundry treatment chamber is formed on the base housing 1.

[0054] Specifically, the base housing 1 can be understood as the basis of the nozzle assembly 100, and the connection head 2 can be understood as the transfer structure of the nozzle assembly 100. The connection head 2 can be connected to the dosing box 200 and an external water source through a conduit. A first docking wall is formed on the base housing 1, and a second docking wall is formed on the connection head 2. When the connection head 2 and the base housing 1 cooperate, the first docking wall and the second docking wall can abut against each other, improving the stability of the cooperation between the connection head 2 and the base housing 1. A first dosing channel 1a is further formed inside the base housing 1, and a transfer channel 2a is formed inside the connection head 2. The communication between the first dosing channel 1a and the transfer channel 2a enables the nozzle assembly 100 to dose additives into the laundry treatment chamber. A transfer inlet 1c communicating with the first dosing channel 1a is formed on the first docking wall, and a transfer outlet 2b communicating with the transfer channel 2a is formed on the second docking wall. During assembly, the first docking wall abuts against the second docking wall, and the transfer inlet 1c of the first dosing channel 1a is aligned with the transfer outlet 2b, enabling the communication between the first dosing channel 1a and the transfer channel 2a.

[0055] In addition, as Figure 5As shown, a pressure relief channel 1d is also formed on the base housing 1. Part of the additives and washing medium that enter the first dosing channel 1a from the transfer inlet 1c of the first dosing channel 1a through the transfer outlet 2b can flow into the pressure relief channel 1d to effectively release the pressure in the first dosing channel 1a, thereby playing a good role in shunting and reducing pressure, and preventing system damage or leakage.

[0056] As Figure 5 shown, according to some embodiments of the present application, a pressure relief hole 1e is formed on the base housing 1, a first enclosing plate 11 is formed on the first docking wall, the first enclosing plate 11 defines a first pressure relief cavity 2c, the first pressure relief cavity 2c is communicated with the transfer inlet 1c of the first dosing channel 1a and is communicated with the pressure relief hole 1e to define a pressure relief channel 1d, and the transfer inlet 1c of the first dosing channel 1a is located in the first pressure relief cavity 2c.

[0057] Specifically, the first enclosing plate 11 can be arranged on the side of the first docking wall facing the second docking wall. The first enclosing plate 11 surrounds and defines the boundary of the first pressure relief cavity 2c. The first pressure relief cavity 2c is communicated with the transfer inlet 1c of the first dosing channel 1a and is communicated with the pressure relief hole 1e to define a pressure relief channel 1d. The pressure relief hole 1e communicates the pressure relief channel 1d with the laundry treatment cavity, so that part of the pressure generated by the fluid placed in the first dosing channel 1a can be smoothly released into the laundry treatment cavity through the pressure relief channel 1d and the pressure relief hole 1e, thereby preventing the internal pressure of the system from being too high.

[0058] It can be understood that the transfer inlet 1c of the first dosing channel 1a is located in the first pressure relief cavity 2c. When the additives and washing medium are dosed through the first dosing channel 1a, the first pressure relief cavity 2c can provide a buffer area. Specifically, when the fluid enters the transfer inlet 1c of the first dosing channel 1a, the pressure generated by the fluid can be relieved and dispersed to a certain extent in the first pressure relief cavity 2c. Subsequently, through the pressure relief channel 1d and the pressure relief hole 1e, these pressures can be smoothly released into the laundry treatment cavity, avoiding damage to the system. Therefore, through the first pressure relief cavity 2c and the pressure relief hole 1e, the nozzle assembly 100 can more effectively manage the pressure during the dosing process of the first dosing channel 1a, ensuring the safe and stable operation of the system. Moreover, in the form of the first pressure relief cavity 2c and the pressure relief hole 1e, there is no need to additionally occupy the space outside the component body or use a complex mechanical structure to achieve pressure release, making the entire nozzle assembly 100 more compact and efficient, and helping to improve the space utilization rate.

[0059] It should be noted that the above-mentioned pressure relief hole 1e can be configured as a hole with a regular shape such as a circular hole, a rectangular hole or an oval hole, so as to facilitate production and improve the uniformity of flow distribution; in some other embodiments, the pressure relief hole 1e can also be configured as a special-shaped hole to provide more complex flow control characteristics or meet specific process requirements.

[0060] Preferably, in some specific embodiments of the present application, the equivalent diameter of the pressure relief hole 1e is configured to be 1.5 mm to 5 mm. It can be understood that if the equivalent diameter of the pressure relief hole 1e is too small, for example, the equivalent diameter of the pressure relief hole 1e is 1.2 mm or 1 mm, etc., the too small flow area will cause poor pressure relief of the pressure relief hole 1e, affecting the stability and safety of the system; if the equivalent diameter of the pressure relief hole 1e is too large, for example, the equivalent diameter of the pressure relief hole 1e is 5.5 mm or 6 mm, etc., the too large hole diameter is likely to cause the pressure to be released too quickly, resulting in excessive loss of washing medium and additives through the pressure relief hole 1e, affecting the clothing cleaning efficiency. Setting the equivalent diameter of the pressure relief hole 1e within the range of 1.5 mm to 5 mm has good balance performance between pressure release and retention, which can avoid excessive loss of washing medium or additives through the pressure relief hole 1e while ensuring timely pressure release, contributing to improving the cleaning efficiency and effect, and enhancing the reliability and service life of the spray head assembly 100.

[0061] As Figure 5 shown, according to some embodiments of the present application, an installation block is formed inside the base housing 1, and a first docking wall is formed at the top of the installation block. The first surrounding plate 11 includes: a first plate body 111 and a second plate body 112.

[0062] Among them, the first plate body 111 is disposed on the side of the installation block and extends to the pressure relief hole 1e; the second plate body 112 is disposed on the top of the first docking wall, and the second plate body 112 surrounds at least part of the outer periphery of the transfer inlet 1c of the first dosing channel 1a. The second plate body 112 is connected to the first plate body 111 to define a first pressure relief chamber 2c.

[0063] Specifically, the installation block is located inside the base housing 1, and a first docking wall is formed at its top. The installation block can not only provide stable support for the first docking wall, but also be used to install or fix other components related to the dosing channel; the first surrounding plate 11 is composed of two parts, the first plate body 111 and the second plate body 112. The first plate body 111 and the second plate body 112 are respectively disposed on the side and top of the installation block, and the first plate body 111 extends to the pressure relief hole 1e, and the second plate body 112 surrounds at least part of the outer periphery of the transfer inlet 1c of the first dosing channel 1a to ensure that the transfer inlet 1c of the first dosing channel 1a is completely surrounded by the first pressure relief chamber 2c, and after the fluid is appropriately buffered in the first pressure relief chamber 2c, it can lead to the pressure relief hole 1e and enter the clothing treatment chamber through the pressure relief hole 1e to achieve smooth buffering and release of the fluid pressure in the first dosing channel 1a. In addition, through the cooperation and support of the installation block, the first docking wall, the first plate body 111 and the second plate body 112, the whole structure is also more stable and reliable, which is beneficial to improving the working reliability and service life of the spray head assembly 100.

[0064] AsFigure 6 As shown, according to some embodiments of the present application, a second shroud is formed on the second docking wall. The second shroud is adapted to abut against the first shroud 11. The second shroud defines a second pressure relief cavity. The second pressure relief cavity is directly opposite to the first pressure relief cavity 2c. The second pressure relief cavity is communicated with the transfer outlet 2b. And the transfer outlet 2b of the transfer channel 2a of the first delivery channel 1a is located within the second pressure relief cavity.

[0065] Specifically, the second shroud may be disposed on the side of the second docking wall facing the first docking wall. The second shroud surrounds and defines the boundary of the second pressure relief cavity. The second pressure relief cavity and the first pressure relief cavity 2c are directly opposite and together form a complete enclosed cavity to provide a buffer and pressure relief space. Among them, the second pressure relief cavity is communicated with the transfer outlet 2b of the transfer channel 2a of the first delivery channel 1a. And the transfer outlet 2b of the transfer channel 2a of the first delivery channel 1a is located within the second pressure relief cavity. After the additive and the washing medium flow through the transfer channel 2a and the transfer outlet 2b, they can enter the cavity formed by the second pressure relief cavity and the first pressure relief cavity 2c for buffer and diversion, so as to reduce the fluid flow rate and pressure entering the first delivery channel 1a, realize diversion and pressure reduction, and protect the equipment from high-pressure damage.

[0066] It should be noted that forming a second pressure relief cavity on the joint head 2 is an exemplary embodiment of the present application. The second pressure relief cavity can be directly opposite to the first pressure relief cavity 2c and together form a closed cavity to provide a buffer and pressure relief space to realize the diversion and pressure relief of the first delivery channel 1a. However, in some other embodiments, the second pressure relief cavity may not be provided on the joint head 2. A plate body may be provided on the side of the first shroud 11 on the first docking wall facing the second docking wall to separate the pressure relief channel 1d from the second docking wall. In this way, the sealing of the pressure relief channel 1d can be ensured, and the pressure relief channel 1d can also have a good diversion and pressure relief function.

[0067] As Figure 6 shown, according to some embodiments of the present application, the second shroud includes: a third plate body 21, a fourth plate body 22, and a fifth plate body 23.

[0068] Among them, the third plate body 21 surrounds at least a part of the outer periphery of the transfer outlet 2b. One end of the fourth plate body 22 is connected to one end of the third plate body 21 and extends in the width direction of the second docking wall. One end of the fifth plate body 23 is connected to the other end of the third plate body 21 and extends in the length direction of the second docking wall. A bent section 231 extending in the width direction of the second docking wall is formed at the other end of the fifth plate body 23. The bent section 231 protrudes from one side in the width direction of the second docking wall. The other end of the fifth plate body 23 is connected to the other end of the fourth plate body 22 to enclose the second pressure relief cavity.

[0069] Specifically, the second enclosing plate is composed of three parts: a third plate body 21, a fourth plate body 22, and a fifth plate body 23. The third plate body 21 surrounds at least a part of the outer periphery of the transfer outlet 2b to ensure that the transfer outlet 2b is completely surrounded within the second pressure relief cavity, guaranteeing that fluid can flow into the second pressure relief cavity. One end of the fourth plate body 22 can be connected to one end of the third plate body 21 in the extending direction. At least a part of the fourth plate body 22 can extend in the width direction of the second docking wall. As a side wall of the second pressure relief cavity, the fourth plate body 22 can jointly define a part of the boundary of the second pressure relief cavity with the third plate body 21. One end of the fifth plate body 23 can be connected to the other end of the third plate body 21 in the extending direction. At least a part of the fifth plate body 23 extends in the length direction of the second docking wall, providing additional support and boundary for the second pressure relief cavity. Moreover, a bent section 231 extending in the width direction of the second docking wall is formed at the other end of the fifth plate body 23. The bent section 231 protrudes from one side of the second docking wall, providing necessary structural support for the closure of the second pressure relief cavity, and enabling the other end of the fifth plate body 23 to be connected to the other end of the fourth plate body 22, thereby completely enclosing the second pressure relief cavity. Through the mutual cooperation of the above-mentioned third plate body 21, fourth plate body 22, and fifth plate body 23, the second pressure relief cavity is completely enclosed. In this way, it can be ensured that the fluid pressure flowing out from the transfer outlet 2b can be fully buffered within the second pressure relief cavity and released through the pressure relief channel 1d, rather than directly acting on other components.

[0070] It should be noted that when the fluid flows through the bent section 231, due to the change in flow direction and velocity, part of the kinetic energy inside it can be consumed. Therefore, the pressure reduction effect can be further enhanced, and at the same time, the amplitude and frequency of oscillation can be reduced, playing a good noise reduction role.

[0071] In addition, in some specific embodiments of the present application, the second plate body 112 and the third plate body 21 are configured as arc-shaped plates. The arc-shaped plates can make the fluid pressure distribute more evenly during the transmission and release processes, avoid excessive local pressure, and better adapt to pressure changes. Therefore, it can also reduce the noise and vibration generated due to pressure fluctuations, improving the user experience.

[0072] As Figure 5 shown, according to some embodiments of the present application, the base housing 1 has a third enclosing plate 12. The third enclosing plate 12 is disposed around and defines a residual water cavity 1f suitable for storing residual water. The base housing 1 is formed with a residual water hole 1g that communicates the residual water cavity 1f with the laundry treatment cavity.

[0073] Specifically, as a part of the base housing 1, the third enclosure 12 is disposed around and defines a specific space, namely, the residual water chamber 1f. The residual water chamber 1f can be used to collect and store the washing medium, additives or moisture that may remain after the spray head assembly 100 stops working or during the cleaning process. Exemplarily, when the first dosing channel 1a is blocked by clothes or impurities, the additives remaining in the first dosing channel 1a can flow into the residual water chamber 1f for storage. The washing water splashed from the laundry treatment chamber into the body of the component can also be stored in the residual water chamber 1f. If these residual waters are not processed in time, they may have a negative impact on the performance and lifespan of the spray head assembly 100 and other electrical components. By introducing the residual water chamber 1f, it can ensure that these residual waters are properly collected and processed, thereby keeping the spray head assembly 100 and other electrical components clean and dry, and improving the working stability and safety of the laundry treatment device 1000.

[0074] A residual water hole 1g is also provided on the body of the component of the present application. The residual water hole 1g connects the residual water chamber 1f and the laundry treatment chamber. The washing water or additives stored in the residual water chamber 1f from the laundry treatment chamber and the dosing channel can flow back into the laundry treatment chamber through the residual water hole 1g, improving the utilization rate of the additives, and thus further enhancing the cleaning ability of the laundry treatment device 1000 for clothes. In addition, the setting of the residual water hole 1g can also prevent the liquid stored in the residual water chamber 1f from overflowing onto other electrical components due to excessive storage, effectively improving the stability and reliability during the operation of the laundry treatment device 1000.

[0075] As Figure 4 shown, according to some embodiments of the present application, an air suction channel 1h is formed on the base housing 1 to connect the first dosing channel 1a and the residual water chamber 1f.

[0076] Specifically, the air suction channel 1h connects the first dosing channel 1a and the residual water chamber 1f, and the residual water chamber 1f is connected to the laundry treatment chamber through the residual water hole 1g. Thus, the air suction channel 1h can introduce the gas in the laundry treatment chamber into the first dosing channel 1a, thereby increasing the gas content of the washing water in the first dosing channel 1a, and further increasing the number of bubbles formed by the discharged washing water, increasing the contact area between the washing water and the clothes, improving the utilization rate of the washing water, and enhancing the washing effect of the clothes. At the same time, by forming bubbles with the discharged 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 laundry treatment chamber to wet the clothes. Compared with the conventional water washing method of introducing a large amount of cleaning water into the laundry treatment chamber, it can effectively reduce the use of cleaning water.

[0077] As Figure 4As shown, according to some embodiments of the present application, the first delivery channel 1a includes a first lumen segment 11a, a second lumen segment 11b, and / or a third lumen segment 11c that are connected in sequence; wherein, along the direction of the first lumen segment 11a towards the second lumen segment 11b, the flow area of the first lumen segment 11a gradually decreases, and / or, along the direction of the second lumen segment 11b towards the third lumen segment 11c, the flow area of the third lumen segment 11c gradually increases.

[0078] Specifically, by arranging the first lumen segment 11a, the second lumen segment 11b, and the third lumen segment 11c in the above structure, a structure similar to a Venturi tube is formed inside the first delivery channel 1a, 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 to decrease. Since the second lumen segment 11b is narrower than the first lumen segment 11a and the third lumen segment 11c, by connecting the suction channel 1h to the second lumen segment 11b, when there is fluid flowing in the first delivery channel 1a, such as when washing water flows in the first delivery channel 1a, under the action of the Venturi effect in the first delivery channel 1a, the gas outside the first delivery channel 1a can enter the first delivery channel 1a, thereby increasing the gas content in the washing water in the first delivery channel 1a, and further increasing the number of bubbles formed by the washing water ejected from the outlet of the first delivery channel 1a, increasing the contact area between the washing water and the clothes, and thus improving the washing effect of the clothes.

[0079] As Figures 1-6 As shown, according to the clothes processing device 1000 of the second aspect embodiment of the present application, the clothes processing device 1000 includes: the spray head assembly 100 described in any one of the above embodiments, and the technical effects generated are the same as those in the above embodiments, and will not be elaborated here.

[0080] In summary, the component body of the spray head assembly 100 is composed of a base housing 1 and a connection head 2. Among them, a pressure relief channel 1d and a pressure relief hole 1e are formed on the base housing 1. The two ends of the pressure relief channel 1d are respectively connected to the first delivery channel 1a and the clothes processing cavity. The fluid can be shunted into the pressure relief channel 1d and released into the clothes processing cavity through the pressure relief hole 1e to achieve shunt pressure relief, so as to reduce the pressure of the first delivery channel 1a, thereby protecting the device from high-pressure damage, and an additional pressure relief port can be cancelled. In this way, it is possible to prevent the washing medium from flowing back from the pressure relief port to the space between the detergent box and the inner and outer barrels of the clothes processing device 1000. The washing medium can all directly act on the clothes, and thus the atomized bubble effect of the detergent can be improved, the utilization rate of the detergent can be increased, the washing effect and efficiency of the clothes can be enhanced, and the washing cost can be saved.
