In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine the different embodiments or examples described in this application, as well as the features of those different embodiments or examples.

[0033] In related technologies, clothing processing equipment requires mixing detergent with water for washing clothes, and the washing effect of existing clothing processing equipment still needs improvement.

[0034] In view of this, embodiments of this application provide a nozzle for use in clothing treatment equipment, which can premix detergent and water to form foam before the actual washing of clothes, thereby improving the washing effect. The detergent can be a liquid detergent, such as detergent, fabric softener, bleach, or disinfectant; the detergent can also be a solid detergent, such as laundry powder, laundry gel, or laundry pods.

[0035] Please see Figure 1 The garment processing device 300 provided in some embodiments of this application includes a device body 310 and a detergent dispensing device 200 according to any embodiment of this application. The device body 310 has a garment cavity 310a; the detergent dispensing device 200 is disposed in the device body 310, and a nozzle 100 is used to supply detergent liquid into the garment cavity. The detergent liquid includes water, or a mixture of detergent and water.

[0036] In some embodiments, combined with Figure 22 The nozzle 100 is installed on the door seal 311 of the main body of the equipment 310.

[0037] In other embodiments, the nozzle 100 is directed directly towards the garment cavity 310a, allowing the mixture of detergent and water to be directly sprayed onto the item to be cleaned. The nozzle 100 can be used in garment processing equipment used to wash clothes, fabrics, backpacks, and other items requiring cleaning; hereinafter collectively referred to as garments. Garment processing equipment can be a washing machine, such as a top-loading washing machine or a front-loading washing machine, or a washer-dryer combo or other equipment with washing functions.

[0038] Please see Figure 2 The detergent dispensing device 200 provided in some embodiments of this application includes a dispensing component 210, a three-way pipe 220, a water inlet pipe 230, a water outlet pipe 240, and a nozzle 100. The dispensing component 210 is used to store or dispense detergent; the water inlet pipe 230, the water outlet pipe 240, and the dispensing component 210 are respectively connected to the three-way pipe 220; the nozzle 100 is connected to the end of the water outlet pipe 240 away from the three-way pipe 220.

[0039] Thus, the detergent and water can be pre-mixed at the T-connector 220 before being mixed at the nozzle 100. The detergent and water undergo a first pre-mixing at the T-connector 220 and a second mixing at the nozzle 100, thereby further improving the washing effect through two mixing processes.

[0040] In some embodiments, please refer to Figures 19 to 21 The three-way pipe 220 has an inlet end 221, a premixing chamber 220a, and an outlet end 222 connected in sequence, and an inlet port 220c located between the inlet end 221 and the outlet end 222. The dispensing component 210 is connected to the inlet port 220c, and the water inlet pipe 230 is connected to the inlet end 221. The inlet port 220c is used to introduce detergent, and water can flow from the inlet end 221 into the premixing chamber 220a and out from the outlet end 222. The three-way pipe 220 provides a premixing space for water and detergent. When the water flows in the premixing chamber 220a, a negative pressure is generated, which can draw detergent from the inlet port 220c into the premixing chamber 220a. By premixing detergent and water in the premixing chamber 220a through the premixing pipe, the washing effect can be further improved.

[0041] Water enters the premixing chamber through the inlet. This water can share the same source as the washing tub, or a dedicated premixing water source can be provided via a water supply device. Detergent is added to the premixing chamber either by introducing detergent pre-stored in a storage container or by manually adding the appropriate amount to the storage container as needed. The order in which water and detergent are added to the premixing chamber is not restricted; either can be added first, or both can be added simultaneously.

[0042] In some embodiments, water can be introduced first from the liquid inlet, followed by detergent and air. In this way, the detergent can come into contact with water immediately after being introduced, reducing the possibility of detergent depositing in the premixing chamber and improving the premixing effect.

[0043] In some embodiments, please refer to Figures 19 to 21 The three-way pipe 220 also includes an air inlet 220b located between the liquid inlet end 221 and the liquid outlet end 222. The detergent dispensing device 200 also includes an air inlet pipe with a first air inlet end and a second air inlet end connected together. The first air inlet end is connected to the air inlet 220b, and the second air inlet end is fixedly connected to the main body 310 of the device. In this way, air, detergent, and water are premixed in the premixing chamber 220a, which can further improve the washing effect.

[0044] In some embodiments, please refer to Figures 19 to 21 The tee 220 can be configured as a venturi tube. The venturi tube includes an inlet section 223, a contraction section 224, a throat section 225, and a diffuser section 226 connected in sequence. The cross-sectional area of ​​the premixing chamber 220a gradually decreases along the fluid flow direction in the contraction section 224, gradually increases along the water flow direction in the diffuser section 226, and remains unchanged along the water flow direction in the throat section 225, which can further improve the premixing effect.

[0045] Please see Figures 3-15 The nozzle 100 provided in this application embodiment includes a housing 10 and a flow guiding member 20. The housing 10 has a cavity 10a and an inlet 10b and an outlet 10c respectively communicating with the cavity 10a; the flow guiding member 20 is disposed in the cavity 10a, and a flow guiding channel is formed between the flow guiding member 20 and the housing 10, so that the fluid generates a flow component with a non-zero angle to the axial direction X of the outlet 10c.

[0046] The spray nozzle 100 provided in this application embodiment generates centrifugal force under the action of the guide member 20, thereby generating atomized particles that are sprayed onto the clothes, which can improve the washing effect.

[0047] In some embodiments, the flow guiding member 20 can be manufactured separately from the housing 10. Manufacturing the flow guiding member 20 separately from the housing 10 can reduce the processing and manufacturing difficulty of the nozzle 100 and reduce production costs.

[0048] For example, the flow guiding member 20 is detachably mounted on the housing 10. If either the housing 10 or the flow guiding member 20 is damaged, only the corresponding part needs to be replaced individually, facilitating future maintenance.

[0049] In other embodiments, the flow guide 20 can be integrally formed with the housing 10, which can reduce assembly steps.

[0050] The shape of the housing 10 is not limited. Exemplarily, the housing 10 is tubular, for example, generally cylindrical. In other embodiments not shown, the housing 10 may also be a square tube, a triangular tube, or an irregularly shaped tube, etc.

[0051] In some embodiments, the housing 10 is shaped like a cylindrical tube. The outer diameter of the housing 10 is 7mm to 15mm, for example, 7mm, 9mm, 10mm, 11mm, 13mm, or 15mm, etc.; the inner diameter of the housing 10 is 5mm to 13mm, for example, 5mm, 7mm, 9mm, 10mm, 11mm, or 13mm, etc. In this way, the dimensions of the housing 10 and the cavity 10a can meet the mixing requirements, reducing the possibility that the dimensions of the housing 10 and the cavity 10a are too large and occupy too much space, or that the dimensions of the housing 10 and the cavity 10a are too small and affect the mixing effect, thereby affecting the washing effect.

[0052] The flow guiding member 20 is disposed inside the cavity 10a. When the fluid passes through the flow guiding member 20, its original movement path will be changed, that is, a flow component with a non-zero angle to the axial direction X of the cavity 10a will be generated. Depending on the shape of the flow guiding member 20, the motion state of the fluid will change differently.

[0053] A fluid refers to a mixture formed by mixing water and detergent and flowing within a cavity, or water flowing within a cavity. The state of the mixture varies depending on the mixing of water and detergent; it can be a liquid, foam, or a mixture of both.

[0054] It is understandable that before the fluid flows into the cavity 10a and reaches the guide member 20, the flow direction is along the axial direction X of the cavity 10a, which is the extension direction of the cavity 10a. The axial direction X of the cavity 10a should not be interpreted as limited to a straight line; the axial direction X of the cavity 10a can also be along a curve. Specifically, different axial directions X are formed according to different extension trends of the cavity 10a.

[0055] In some embodiments, the outer contour of the flow guide 20 is adapted to the inner wall of the housing 10. In this way, the outer contour of the flow guide 20 can be inlaid within the inner wall of the housing 10.

[0056] In some embodiments, the outer contour of the flow guide 20 is spaced apart from the inner wall of the housing 10, and the flow guide 20 is disposed on the inner wall of the housing 10 by other structures, such as by a cantilever beam-type connecting rod.

[0057] The extension length of the flow guide member 20 is not limited, and at least a portion of the flow guide member 20 is located within the cavity 10a. For example, see [link to relevant documentation]. Figure 5 , Figure 9 and Figure 12In some embodiments, the extension length of the flow guiding member 20 is less than the extension length of the cavity 10a. After the flow guiding member 20 is disposed in the cavity 10a, space is left in both front and rear of the cavity 10a along the fluid flow direction. Alternatively, in other embodiments, the extension length of the flow guiding member 20 is equal to the extension length of the cavity 10a, and space may be left between the flow guiding member 20 and the outlet 10c. The flow guiding member 20 may protrude from the inlet 10b. After the nozzle 100 and the water outlet pipe 240 are installed, part of the flow guiding member 20 is located in the water outlet pipe 240. Alternatively, in other embodiments, the extension length of the flow guiding member 20 is greater than the extension length of the cavity 10a. The flow guiding member 20 is disposed in the cavity 10a and may protrude from the inlet 10b. After the nozzle 100 and the water outlet pipe 240 are installed, part of the flow guiding member 20 is located in the water outlet pipe 240.

[0058] The position of the flow guiding member 20 within the cavity 10a is not limited and can be adapted to meet specific needs. For example, the flow guiding member 20 may be located at the end of the cavity 10a. Alternatively, the flow guiding member 20 may be located at the inlet 10b of the cavity 10a, or at the outlet 10c of the cavity 10a, or at the center of the cavity 10a.

[0059] It is understandable that when the flow guide member 20 is located at the inlet 10b of the cavity 10a, the cross-sectional area of ​​the flow cavity in the water outlet pipe 240 connected upstream of the nozzle 100 is greater than or equal to the cross-sectional area at the inlet 10b of the cavity 10a, so that the cross-sectional area of ​​the flow cavity in the water outlet pipe 240 connected upstream of the nozzle 100 is greater than the cross-sectional area of ​​the flow guide channel, thereby improving the mixing effect of detergent and water.

[0060] In some embodiments, please refer to Figure 5 , Figure 9 and Figure 12 The number of flow guiding channels is unlimited. When the flow guiding component 20 is located inside the cavity 10a, i.e., at a certain distance from the inlet 10b, the sum of the cross-sectional areas of all flow guiding channels is less than the cross-sectional area of ​​the inlet 10b, but greater than the cross-sectional area of ​​the outlet 10c. When there are multiple outlets 10c, the sum of the cross-sectional areas of all flow guiding channels is greater than the sum of the cross-sectional areas of all outlets 10c.

[0061] Thus, since the sum of the cross-sectional areas of the guide channels is less than the cross-sectional area of ​​the inlet 10b, the fluid entering the guide channels generates pressure, the flow velocity begins to increase, and under the guidance of the guide member 20, a larger centrifugal force is generated. Under the action of centrifugal force, the detergent and water are further mixed. The sum of the cross-sectional areas of the guide channels is greater than the cross-sectional area of ​​the outlet 10c, so that the fluid generates further pressure at the outlet 10c, forming an atomization effect, which can improve the washing effect.

[0062] In some embodiments, please refer to Figure 5, Figure 9 and Figure 12 The cavity 10a includes a accommodating cavity 10a1 and a mixing cavity 10a2 that are connected, with the mixing cavity 10a2 located between the accommodating cavity 10a1 and the outlet 10c.

[0063] Furthermore, the shell 10 forms a step 12 at the junction of the accommodating cavity 10a1 and the mixing cavity 10a2, and the flow guiding member 20 is disposed in the accommodating cavity 10a1, with the step 12 limiting the flow guiding member 20.

[0064] The step 12 can be a limiting rib or a limiting protrusion, or it can be a step formed by the cross-section of the mixing chamber 10a2 being smaller than the cross-section of the receiving chamber 10a1. The step 12 can support and limit the flow guiding member 20, so that the flow guiding member 20 is fixed in a fixed position along the flow direction in the receiving chamber 10a1, reducing the possibility of the flow guiding member 20 moving towards the mixing chamber 10a2. The fluid enters the mixing chamber 10a2 under the action of centrifugal force generated by the flow guiding channel, so that the detergent and water are fully mixed in the mixing chamber 10a2. The step 12 maintains the mixing chamber 10a2 at a preset volume, which can reduce the possibility that the volume of the mixing chamber 10a2 is too small and affects the mixing effect.

[0065] In some embodiments, please refer to Figure 5 , Figure 9 and Figure 12 The cross-sectional area of ​​the mixing chamber 10a2 is larger than that of the flow guiding channel. This facilitates the re-mixing of fluids after they pass through the mixing chamber 10a2 and reach the outlet 10c. For example, the cross-sectional area of ​​the mixing chamber 10a2 is equal to that of the receiving chamber 10a1, the step 12 is a limiting rib or limiting protrusion, and the flow guiding member 20 is disposed in the receiving chamber 10a1 such that the cross-sectional area of ​​the flow guiding channel is smaller than that of the mixing chamber 10a2. Alternatively, the cross-sectional area of ​​the mixing chamber 10a2 is smaller than that of the receiving chamber 10a1 to form the step 12; after the flow guiding member 20 is disposed in the receiving chamber 10a1, the cross-sectional area of ​​the flow guiding channel is smaller than that of the mixing chamber 10a2.

[0066] In some embodiments, at least one of the housing 10 and the flow guiding member 20 is made of plastic. For example, the housing 10 is a one-piece molded plastic part, and the flow guiding member 20 is a metal part. Alternatively, the flow guiding member 20 is a one-piece molded plastic part, and the housing 10 is a metal part. Alternatively, the housing 10 and the flow guiding member 20 are each one-piece molded plastic parts. Alternatively, the housing 10 and the flow guiding member 20 are combined into a one-piece molded plastic part.

[0067] In some embodiments, the flow guiding member 20 is manufactured separately from the housing 10, and the flow guiding member 20 and the housing 10 are interference-fitted. This improves the connection strength between the flow guiding member 20 and the housing 10, and reduces the possibility of the flow guiding member 20 moving relative to the housing 10. For example, at least one of the housing 10 and the flow guiding member 20 is made of plastic, and the interference fit can be achieved through deformation of the plastic part.

[0068] In some embodiments, please refer to Figure 5 , Figure 9 and Figure 12 The housing 10 has a rib 11 extending along the axial direction X of the cavity 10a on the inner wall, and the flow guide member 20 is interference-fitted with the rib 11. In this way, the mating area between the housing 10 and the flow guide member 20 can be reduced, local interference fit can be achieved, and the assembly difficulty of the interference fit between the housing 10 and the flow guide member 20 can be reduced.

[0069] In some embodiments, please refer to Figure 7 , Figure 10 and Figure 13 Multiple ribs 11 are arranged at intervals along the circumference of the cavity 10a on the inner wall of the shell 10. The connection strength between the shell 10 and the flow guide member 20 is improved by increasing the number of ribs 11.

[0070] In some embodiments, please refer to Figure 6 The upper part of the rib 11 has a guide portion 111 to guide the assembly of the flow guide member 20. In this way, the assembly difficulty of the interference fit between the housing 10 and the flow guide member 20 can be further reduced.

[0071] In some embodiments, the cross-sectional area of ​​the guide portion 111 gradually increases from the inlet 10b of the housing 10 toward the outlet 10c of the housing 10, which facilitates the assembly of the flow guiding member 20.

[0072] In some embodiments, the number of outlets 10c is at least one.

[0073] In some embodiments, there is only one outlet 10c. This allows for a larger design size for the outlet 10c, facilitating the fabrication of its structure. For example, a chamfer can be applied to the outlet 10c.

[0074] In some embodiments not shown, the number of outlets 10c is two or more, such as two, three, or four, etc., with each outlet 10c spaced apart. This allows for an increase in the number of outlets 10c, a reduction in the cross-sectional area of ​​a single outlet 10c, and an expansion of the spraying range of the mixture from each outlet 10c.

[0075] In some embodiments, when there are multiple outlets 10c, the axial X-angle between each outlet 10c and the cavity 10a can be set to be the same or different. When the axial X-angle between each outlet 10c and the cavity 10a is set to be different, the mixture can be sprayed in multiple directions. The dimensions of the outlets 10c can be the same or different.

[0076] In some embodiments, please refer to Figure 5 , Figure 9 and Figure 12 The housing 10 has a chamfer 13 at the outlet 10c, which expands from the inside out. The chamfer 13 allows the mixture to be ejected in a cone shape. When there are multiple outlets 10c, the chamfer 13 can be set on one of the outlets 10c, and the outlet 10c with the chamfer 13 can be the main outlet.

[0077] In some embodiments, please refer to Figure 5 , Figure 9 and Figure 12 The housing 10 includes a straight section 101 and a curved section 102. The straight section 101 has an inlet 10b, and the curved section 102 has an outlet 10c. The angle between the straight section 101 and the curved section 102 is 0° to 75°. For example, the angle between the straight section 101 and the curved section 102 can be 0°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, or 75°, etc. This allows the mixture to be sprayed toward the clothing. When there are multiple outlets 10c, the axial X angle between each outlet 10c and the cavity 10a located in the straight section 101 can be the same or different.

[0078] In some embodiments, please refer to Figure 5 , Figure 9 and Figure 12 The housing 10 includes a straight section 101 and a curved section 102. There are two outlets 10c, which are located in the curved section 102 respectively. The two outlets 10c have different axial X angles from the cavity 10a located in the straight section 101.

[0079] In some embodiments, please refer to Figures 16 to 18 The housing 10 is a straight section 101, and the outlet 10c includes a first outlet 10c1 and a second outlet 10c2. The first outlet 10c1 and the second outlet 10c2 have different axial X angles from the cavity 10a.

[0080] For example, the axial X angle between the first outlet 10c1 and the cavity 10a is 0°, and the axial X angle between the second outlet 10c2 and the cavity 10a is 90°.

[0081] In some embodiments, please refer to Figures 22 to 29The main body 310 includes a door seal 311, and a nozzle 100 is disposed on the door seal 311. The main body 310 also includes a door 312 and a glass bowl 313. The glass bowl 313 is disposed on the door 312 and has an inclined surface 3131 facing the clothing cavity. The first outlet 10c1 faces the inclined surface 3131. The outlet 10c includes a first outlet 10c1 and a second outlet 10c2, and there is at least one first outlet 10c1 and a second outlet 10c2. The first outlet 10c1 faces the inclined surface 3131, and the second outlet 10c2 faces the door seal 311.

[0082] Thus, by providing the second outlet 10c2, residual foam on the door seal 311 can be eliminated, allowing the foam to be carried into the garment cavity 310a, improving the washing effect. The mixture is sprayed from the first outlet 10c1 onto the inclined surface 3131, further enhancing the mixing effect of detergent and water, and dispersing it more evenly into the garment cavity 310a, thereby improving the washing effect. In some embodiments, when the nozzle 100 provides clean water to the garment cavity 310a, the clean water flows from the second outlet 10c2 to the door seal 311, which can eliminate foam.

[0083] In some embodiments, please refer to Figure 5 , Figure 9 and Figure 12 The housing 10 has a chamfer 13 at the outlet 10c, which expands from the inside out. The axial X angle between the outlet 10c and the cavity 10a is 0~75°. In this way, the chamfer 13 allows the mixture to be sprayed out in a cone shape. Combined with the axial X angle of the outlet 10c relative to the cavity 10a, the mixture is sprayed onto the clothing more evenly.

[0084] In some embodiments, please refer to Figure 5 , Figure 9 and Figure 12 The inner diameter d of outlet 10c is 2~7mm. For example, the inner diameter d of outlet 10c can be 2mm, 3mm, 4mm, 5mm, 6mm, or 7mm, etc. When there are multiple outlets 10c, their inner diameters can be the same or different. This allows for consideration of the inlet water flow rate, preventing the outlet 10c from being too small and causing blockage, and creating an atomization effect from the outlet 10c, with atomized particles reaching the micron level.

[0085] In some embodiments, please refer to Figures 7 to 14 The flow guiding component 20 includes a flow guiding element 21, which is disposed in the cavity 10a and configured to form at least one flow guiding channel between itself and the housing 10.

[0091] In other embodiments not shown, the number of spiral blades can be one, three, or more, etc. It is understood that when the number of spiral blades is one, the number of flow channels is one.

[0092] In some embodiments, the pitch of the spiral blade is 5mm to 20mm, for example, 5mm, 8mm, 10mm, 13mm, 15mm, 18mm, or 20mm, etc.; the length of the spiral blade is 5mm to 20mm, for example, 5mm, 8mm, 10mm, 13mm, 15mm, 18mm, or 20mm, etc. In this way, the pitch and length of the spiral blade can meet the mixed requirements.

[0096] In some embodiments, please refer to Figure 8 and Figure 11 The smooth outer periphery of the guide 23 allows the fluid to flow more smoothly along the surface of the guide 23.

[0097] In some embodiments, the outer contour of the guide 23 at the end away from the flow guide 21 is smaller than the outer contour at the end near the flow guide 21, so as to guide the mixture.

[0098] In some embodiments, the guide 23 can be a cone of various shapes, such as a triangular pyramid, a square pyramid, or a circular cone, with the tip of the cone located upstream of the bottom of the cone along the direction of fluid movement. The guide 23 can also be a triangular plate.
