Description

Technical Field

[0001] The present application relates to the field of clothing processing, and in particular to a clothing processing device. Background Art

[0002] In the related art, the clothing processing equipment mainly includes a clothing processing drum, a detergent box, and a pipeline, which connects the detergent box and the clothing processing drum. When washing clothes, the external water flow is passed into the detergent box to form a detergent solution, and finally enters the clothing processing drum through the pipeline to add detergent. However, detergents, especially washing powder, often do not dissolve fully and mix unevenly with the water flow, resulting in insufficient utilization of the detergent, poor cleaning effect, and affecting user experience. In addition, some related technologies use clean water to dilute the solution at the drain outlet of the detergent box, and then flow it along the pipeline to the clothing processing chamber, but the cleaning effect is still poor. Utility Model Content

[0003] In view of this, the embodiments of the present application hope to provide a clothing processing device that can effectively promote the dissolution of detergent and improve the spraying effect of the detergent mixed solution when it enters the clothing processing chamber, so as to enhance the cleaning effect.

[0004] An embodiment of the present application provides a clothes processing device, comprising:

[0005] a clothes processing chamber, for accommodating clothes to be processed;

[0006] A detergent dispensing device, comprising a mixing space, a water spray port, a first water channel and a second water channel, wherein the first water channel and the second water channel are used to transport fluid, the first water channel connecting a water source and a water inlet end of the mixing space, and the second water channel connecting a water source and a water inlet end of the mixing space;

[0007] The fluid in the first water channel is a detergent mixed solution, and the fluid in the first water channel and the fluid in the second water channel converge in the mixing space. The mixed fluid in the mixing space is sprayed toward the clothing processing chamber through the water spray port; wherein, the mixing space is located in the clothing processing chamber.

[0008] In some embodiments, the water spray port is disposed on a wall of the mixing space.

[0009] In some embodiments, a wall of the mixing space has a first port, and the fluid of the first water channel enters the mixing space from the first port, and the first port constitutes a water outlet end of the first water channel.

[0010] In some embodiments, the outlet end of the second water channel extends into the mixing space; or

[0011] The wall surface of the mixing space has a second port, and the fluid of the second water channel enters the mixing space from the second port, and the second port constitutes the water outlet end of the second water channel.

[0012] In some embodiments, the water outlet end of the second water channel faces the water outlet.

[0013] In some embodiments, a diameter-reducing section is provided at the end of the second water channel to increase the flow rate at the water outlet end of the second water channel.

[0014] In some embodiments, the detergent dispensing device includes a turbulent flow structure, which is disposed in the second water channel and is configured to provide a circumferential velocity component to the fluid in the second water channel.

[0015] In some embodiments, the laundry processing device includes a drum assembly, a nozzle unit, and a door seal ring, wherein the door seal ring is provided on the front side of the drum assembly;

[0016] The spray head unit includes a shell portion, which is located radially inward of the door sealing ring. The shell portion is formed with the mixing space and the water spray port.

[0017] In some embodiments, the nozzle unit includes a nozzle, which is disposed inside the mixing space. An outlet of the nozzle constitutes a water outlet end of the second water channel, and the outlet of the nozzle faces the water spray port.

[0018] In some embodiments, the spray head unit further includes a first joint pipe and a second joint pipe, wherein the first joint pipe and the second joint pipe are both connected to the shell;

[0019] The space inside the first joint pipe forms a part of the first water channel, and the space inside the second joint pipe forms a part of the second water channel. The door sealing ring has a first mounting opening and a second mounting opening. The first joint pipe is passed through the first mounting opening, and the second joint pipe is passed through the second mounting opening.

[0020] In the clothing processing device of the embodiment of the present application, the detergent mixed solution intersects with the fluid in the second water channel before being sprayed onto the clothes to be treated. When the two fluids intersect, the two fluids are mixed and impacted more fully in the mixing space, which can further promote the dissolution of the detergent and also promote the foaming of the detergent.

[0021] Since the mixing space is located in the clothing processing chamber, the distance from the intersection of the mixed fluid of the first water channel and the second water channel to the time when it is dropped onto the clothing to be processed can be shortened, reducing the degree of foaming of the foam detergent, which is conducive to adding a large amount of foam detergent to the clothing to be processed, thereby improving the cleaning effect.

[0022] In addition, in the embodiment of the present application, the distance from the intersection position of the fluid in the first water channel and the second water channel to the spraying onto the clothes to be treated is short, and the water outlet shape after the intersection can be better preserved.

[0038] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0039] In the description of the embodiments of the present application, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inner", "outer", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0040] In the description of the embodiments of this application, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium.

[0041] In the embodiments of the present application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, a first feature being "above," "above," and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0042] In the description of this specification, reference to the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example.

[0043] The present application embodiment provides a clothes processing device. Figure 1 and Figure 2 The clothing processing device includes a clothing processing chamber and a detergent dispensing device 100, and the clothing processing chamber is used to accommodate clothing to be processed.

[0044] The form of the clothes processing device is not limited, for example, a drum washing machine, a pulsator washing machine, a drum washer-dryer, a pulsator washer-dryer, etc. This specification takes a drum washing machine as an example for description.

[0045] See also Figure 2 、 Figure 4 and Figure 7 The detergent dispensing device 100 includes a mixing space 20a, a water outlet 201b, a first water channel 40A, and a second water channel 50A. The first water channel 40A and the second water channel 50A are used to transport fluid. The first water channel 40A connects a water source to the water inlet of the mixing space 20a, while the second water channel 50A connects a water source to the water inlet of the mixing space 20a. It is understood that both the first water channel 40A and the second water channel 50A transport fluid into the mixing space 20a.

[0046] It should be noted that the first waterway 40A refers to the flow path of the fluid, not specifically a pipeline structure. The second waterway 50A refers to the flow path of the fluid, not specifically a pipeline structure. Figures 1 to 11 , the dotted lines with arrows in the accompanying drawings indicate the flow direction of the fluid.

[0047] The fluid in the first water channel 40A is a detergent mixed solution.

[0048] It should be noted that the detergent mixed solution mentioned in this specification is merely for convenience of description and refers to a mixed solution containing dissolved detergent. Its mass percentage concentration is not limited, and it does not necessarily mean that the detergent is completely dissolved. The detergent can be in any form and can be powdered laundry detergent, liquid laundry detergent, or softener.

[0049] The fluid of the second water channel 50A is not limited and can be tap water or a fluid containing dissolved detergent components. For example, in some embodiments, the clothing processing device further includes a circulation pump, and the water inlet end of the second water channel 50A is connected to the water outlet of the circulation pump.

[0050] The fluid in the first water channel 40A and the fluid in the second water channel 50A merge into the mixing space 20a, and the mixed fluid in the mixing space 20a is sprayed toward the clothing processing chamber through the water spray port 201b. The mixing space 20a is located in the clothing processing chamber.

[0051] It should be noted that the above-mentioned mixing space 20a is a chamber formed in the physical structure. The mixing space 20a allows the detergent mixed solution in the first water channel 40A and the fluid in the second water channel 50A to mix more fully, and then the mixed fluid is discharged into the clothing processing chamber through the water nozzle 201b.

[0052] In the clothing processing device of the embodiment of the present application, the detergent mixed solution intersects with the fluid in the second water channel 50A before being sprayed onto the clothes to be treated. When the two fluids intersect, the two fluids are mixed and impacted more fully in the mixing space 20a, which can further promote the dissolution of the detergent and also promote the foaming of the detergent.

[0053] Since the mixing space 20a is located in the clothing processing chamber, the distance from the intersection of the mixed fluid of the first water channel 40A and the second water channel 50A to the time when it is dropped onto the clothing to be processed can be shortened, thereby reducing the degree of foaming of the foam detergent, which is conducive to adding a large amount of foam detergent to the clothing to be processed, thereby improving the cleaning effect.

[0054] In addition, in the embodiment of the present application, the distance from the intersection position of the fluid in the first water channel 40A and the second water channel 50A to the spraying onto the clothes to be treated is short, and the water outlet shape after the intersection can be better preserved.

[0055] For example, see Figure 1 The clothing processing device includes a housing (not shown), a door (not shown), a barrel assembly 10, and a door seal 60. The door seal 60 is arranged on the front side of the barrel assembly 10. The barrel assembly 10 is arranged in the housing. The housing is provided with an opening communicating with the interior of the barrel assembly 10, and the door is used to open or close the opening. The door seal 60 is used to seal the gap between the barrel assembly 10 and the opening of the housing. When the door closes the opening, the door is sealed to the door seal 60. Thus, the communicating space formed between the interior of the barrel assembly 10, the door seal 60, and the door constitutes a clothing processing chamber.

[0056] For example, in some embodiments, see Figure 2 and Figure 3The detergent dispensing device 100 includes a detergent supply assembly 30 having a detergent dispensing chamber through which the fluid in the first water channel 40A flows. The detergent dispensing chamber is used to accommodate detergent. In other words, the detergent supply assembly 30 is located on the first water channel 40A. Under the action of the fluid in the first water channel 40A, the detergent can dissolve in the fluid in the first water channel 40A to form a detergent mixed solution.

[0057] In some other embodiments, the detergent supply assembly 30 is in communication with the first water channel 40A, and the detergent and water in the detergent supply assembly 30 are mixed and then fed into the first water channel 40A to form a detergent mixed solution.

[0058] Illustratively, the water spray port 201b is used to spray water obliquely downward toward the rear side of the laundry treatment chamber.

[0059] That is, see Figure 5 Water outlet 201b sprays water downward and rearward. The fluid at water outlet 201b has both a downward velocity component and a velocity component along the axial rear side of the laundry processing chamber. That is, the centerline n of water outlet 201b forms an acute angle φ with the reference plane m. The reference plane m is perpendicular to the axis of the laundry processing chamber.

[0060] The value of the acute angle φ is not limited.

[0061] Exemplarily, the acute angle φ formed between the centerline n of the water spray port 201b and the reference plane m is 30° to 70°, i.e., 30°≤φ≤70°. Examples include 30°, 45°, 50°, 60°, 70°, etc. This allows the fluid sprayed from the water spray port 201b to be sprayed onto the clothing in the laundry treatment chamber as much as possible, quickly soaking the clothing, improving detergent utilization, and enhancing the cleaning effect.

[0062] For some examples, see Figure 7 and Figure 8 The water outlet 201b is disposed on the wall of the mixing space 20a. In other words, the mixed fluid in the mixing space 20a is immediately discharged into the laundry processing chamber after passing through the wall of the mixing space 20a, without the need for an additional drainage pipe. This reduces the impact of the water outlet of the mixing space 20a on the fluid.

[0063] For some examples, see Figure 8 The water outlet end of the second water channel 50A is directed toward the water outlet 201b. This is beneficial to maintaining the water outlet shape of the water outlet end of the second water channel 50A, so that the fluid from the water outlet 201b can retain its movement trend as much as possible after being ejected from the water outlet end of the second water channel 50A.

[0064] For some examples, see Figure 12 and Figure 13The wall of the mixing space 20a has a first port (reference y), and the fluid of the first water channel 40A enters the mixing space 20a from the first port, and the first port constitutes the water outlet of the first water channel 40A. No additional piping structure is required, and the structure is simple.

[0065] For some examples, see Figure 13 , the outlet end of the second water channel 50A (reference x) extends into the mixing space 20a. That is, the fluid in the second water channel 50A is ejected from the pipe structure in the mixing space 20a. In other embodiments, refer to Figure 12 The wall of the mixing space 20a has a second port, and the fluid of the second water channel 50A enters the mixing space 20a from the second port, and the second port constitutes the water outlet end of the second water channel 50A.

[0066] In some embodiments, for example, see Figure 9 The laundry processing apparatus includes a first tubular structure 1001 and a second tubular structure 1002. The second tubular structure 1002 at least partially extends into the first tubular structure 1001 in a direction intersecting the extension direction of the first tubular structure 1001. The mixing space 20a is formed as the cylindrical projection of the second tubular structure 1002 along its extension direction, forming an enclosed space within the first tubular structure 1001. The water spray port 201b (referenced at position z) is provided on the wall surface of the first tubular structure 1001. In this embodiment, the portion of the first tubular structure 1001 located upstream of the mixing space 20a (referenced at position y) defines a portion of the first water channel 40A, and a portion of the second water channel 50A (referenced at position x) is formed by the second tubular structure 1002.

[0067] For some examples, see Figure 10 The laundry processing device includes a first tubular structure 1001, a second tubular structure 1002, and a third tubular structure 1003, which are connected in a "Y" shape. The mixing space 20a is formed by the projected cylindrical surface formed by the intersection of the first and second tubular structures 1001, 1002 along the direction of fluid movement, and the interior space of the third tubular structure 1003. The water outlet 201b is located at one end of the third tubular structure 1003 (reference point z). The interior of the first tubular structure 1001 forms part of the first water channel 40A, while the interior of the second tubular structure 1002 forms part of the second water channel 50A.

[0068] For some examples, see Figure 11The laundry processing apparatus includes a first tubular structure 1001 and a second tubular structure 1002. At least a portion of the second tubular structure 1002 extends into the interior of the first tubular structure 1001 along the extension direction of the first tubular structure 1001. A water spray port 201b is provided at one end of the first tubular structure 1001 (referenced at position z). A mixing space 20a is defined as the space within the first tubular structure 1001 extending from the water outlet end of the second tubular structure 1002 (referenced at position y) to the water spray port 201b. The portion of the first tubular structure 1001 located upstream of the mixing space 20a defines a portion of the first water channel 40A, and a portion of the second water channel 50A is formed by the second tubular structure 1002.

[0069] For some examples, see Figure 5 The end of the second waterway 50A is provided with a reduced diameter section 22 to increase the flow rate at the outlet of the second waterway 50A. For example, in some embodiments, the end of the reduced diameter section 22 forms the outlet of the second waterway 50A. In other words, the fluid in the second waterway 50A is ejected from the end of the reduced diameter section 22. In other embodiments, the end of the reduced diameter section 22 is further connected to a constant diameter section and / or an expanded diameter section, which form the outlet of the second waterway 50A.

[0070] It should be noted that, along the direction of fluid movement, the flow area of ​​the fluid in the above-mentioned diameter-reducing section 22 becomes smaller, the flow area in the above-mentioned diameter-equalizing section remains basically unchanged, and the flow area in the above-mentioned diameter-expanding section becomes larger.

[0071] The reduced diameter section 22 can increase the impact force of the fluid by limiting the flow area when the fluid is ejected, thereby generating a greater impact force on the fluid at the outlet end of the first water channel 40A, thereby achieving a better mixing effect.

[0072] At the same time, the reduced diameter section 22 makes the water outlet end of the second water channel 50A have a larger injection speed, which can generate obvious negative pressure in a relatively large area around it, so that the fluid at the water outlet end of the first water channel 40A is sucked in under the action of the negative pressure and mixed with the fluid in the second water channel 50A, thereby improving the mixing and foaming effects.

[0073] In some embodiments, the detergent dispensing device 100 includes a turbulent flow structure 21 , which is disposed in the second water channel 50A and is configured to provide a circumferential velocity component to the fluid in the second water channel 50A.

[0074] For some examples, see Figure 5 The detergent dispensing device 100 further includes a turbulent flow structure 21 , which is disposed in the second water channel 50A and is configured to provide a circumferential velocity component to the fluid in the second water channel 50A.

[0075] The above-mentioned circumferential velocity component refers to the fluid in the second water channel 50A after passing through the turbulent structure 21, whose velocity direction in the circumferential direction of the second water channel 50A is not zero, and the circumferential direction of the second water channel 50A is perpendicular to the extension direction of the second water channel 50A.

[0076] In this embodiment, the turbulent structure 21 allows part of the fluid to have both a circumferential movement speed and a forward flow speed, so that part of the fluid roughly moves in a spiral. When the fluid is ejected from the outlet end of the second waterway 50A, the fluid is facilitated to diffuse in a conical shape, with a wider radiation range and better visual effect.

[0077] Exemplarily, the turbulent flow structure 21 includes one or more spiral blades, which divide at least a partial length of the second water channel 50A where the spiral blades are located into a plurality of sub-flow channels.

[0078] The above-mentioned multiple refers to the number of blades being multiple, which can be two, three or more, that is, the number of heads of the spiral is not less than two, and does not limit the number of turns of the spiral.

[0079] After the fluid passes through the spiral blades, it exhibits a spiral motion. The spiral blades have a simple structure, good flow disturbance effect on the fluid, and low resistance, reducing energy loss when the fluid passes through.

[0080] In some embodiments, the laundry treatment apparatus includes a spray head unit 200 , which includes a housing 201 located radially inward of a door seal 60 . The housing 201 defines a mixing space 20a and a water spray port 201b . The door seal 60 provides mounting support for the spray head unit 200 .

[0081] It is understood that the first water channel 40A and the second water channel 50A are both connected to the nozzle unit 200 and transport fluid to the interior of the nozzle unit 200, so that the fluids in the first water channel 40A and the second water channel 50A converge in the mixing space 20a and are discharged into the laundry treatment chamber through the water spray port 201b. The nozzle unit 200 serves to gather the first water channel 40A and the second water channel 50A.

[0082] Exemplarily, the spray head unit 200 further includes a first joint pipe 204 and a second joint pipe 205, both of which are connected to the housing 201. The space within the first joint pipe 204 forms a portion of the first waterway 40A, and the space within the second joint pipe 205 forms a portion of the second waterway 50A. The first waterway 40A delivers fluid into the spray head unit 200 via the first joint pipe 204, and the second waterway 50A delivers fluid into the spray head unit 200 via the second joint pipe 205.

[0083] The door seal ring 60 has a first mounting opening and a second mounting opening, the first joint pipe 204 is passed through the first mounting opening, and the second joint pipe 205 is passed through the second mounting opening. In this way, the circumferential position of the spray head unit 200 relative to the door seal ring 60 is defined.

[0084] For some examples, see Figure 5 The spray head unit 200 includes a baffle 203 formed on the top side of the housing 201. The first and second joint pipes 204 and 205 are formed on the same side of the baffle 203. When the spray head unit 200 is installed, the baffle 203 can abut against the radially inner side of the door seal 60, thereby limiting the radial position of the spray head unit 200 relative to the door seal 60.

[0085] For some examples, see Figure 7 and Figure 8 The nozzle unit 200 includes a nozzle 202, which is disposed inside the mixing space 20a. The outlet of the nozzle 202 constitutes the water outlet end of the second water channel 50A, and the outlet of the nozzle 202 faces the water outlet 201b.

[0086] The fluid in the second water channel 50A is ejected from the outlet of the nozzle 202, impacting the detergent mixed solution in the first water channel 40A within the mixing space 20a, and directly entering the laundry processing chamber through the water spray port 201b. In other words, the shape of the water outlet of the second water channel 50A is slightly attenuated within the mixing space 20a, and the shape of the water is similar to that when it is ejected from the outlet of the nozzle 202, thereby driving the fluid in the mixing space 20a to be ejected.

[0087] For example, the nozzle 202 is formed with a reduced diameter section 22, and the turbulence structure 21 is disposed in the second connecting pipe 205, upstream of the reduced diameter section 22. After passing through the turbulence structure 21 and the reduced diameter section 22, the fluid in the second waterway 50A is ejected from the nozzle 202 outlet at an increased velocity, with a circumferential velocity component. This allows the water outlet 201b to present a more visually appealing conical shape, and the ejected mixed fluid is more dispersed, directly spraying onto the laundry, enhancing cleaning performance.

[0088] The nozzle unit 200 can be a one-piece component, that is, the shell 201, nozzle 202, baffle 203, first connector pipe 204, and second connector pipe 205 are integrally formed, for example, by injection molding. Of course, the nozzle unit 200 can also be a separate component that is assembled after processing.

[0089] For some examples, see Figure 7 and Figure 8A guide channel 201a is formed inside the shell 201, and the guide channel is connected to the mixing space 20a. The end of the guide channel 201a constitutes the water outlet end of the first waterway 40A, and along the flow direction of the fluid, the flow cross-section of the guide channel 201a gradually increases.

[0090] It will be appreciated that the end of the diversion channel 201a near one end of the mixing space 20a has the largest flow cross-section. When the fluid enters the shell 201, guided by the diversion channel 201a, it tends to concentrate toward the end near the mixing space 20a, filling the mixing space 20a as much as possible and thoroughly mixing with the fluid at the outlet of the second waterway 50A. This also reduces the velocity of the fluid entering the mixing space 20a from the first waterway 40A, making the impact of the fluid from the second waterway 50A more pronounced.

[0091] For some examples, see Figure 7 The outlet cross-section y of the flow channel 201a is larger than the outlet cross-section x of the nozzle 202, and smaller than the outlet cross-section z of the water outlet port 201b. This effectively suppresses backflow caused by a large flow difference between the first water channel 40A and the second water channel 50A, thereby minimizing the backflow of fluid within the mixing space 20a back into the first water channel 40A.

[0092] For some examples, see Figure 4 、 Figure 6 and Figure 7 The first joint pipe 204 and the second joint pipe 205 are arranged along the housing 201, extending along the first direction R. It should be noted that the first direction R is generally tangential to the door seal 60. This facilitates the circumferential arrangement of the first joint pipe 204 and the second joint pipe 205 along the door seal 60. It should be noted that the distance between the first joint pipe 204 and the second joint pipe 205 should be sufficient to prevent interference when connecting the pipes.
