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] The detergent dispensing device comprises 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 water inlet end of the first water channel is connected to a water source, and the water inlet end of the second water channel is connected to a water source;

[0007] The fluid in the first water channel is a detergent mixed solution. The fluid in the first water channel intersects with the fluid in the second water channel, and the intersecting position is located in the clothing processing chamber.

[0008] In some embodiments, the detergent dispensing device further includes a mixing space and a water spray port, wherein the mixing space is located in the clothing processing chamber, the fluid in the first water channel and the fluid in the second water channel converge in the mixing space, and the mixed fluid in the mixing space is dispensed into the clothing processing chamber through the water spray port.

[0009] In some embodiments, the water spray port is used to spray water obliquely downward toward the rear side of the laundry processing chamber.

[0010] In some embodiments, the acute angle formed by the center line of the water spray port and a reference plane is 30° to 70°, wherein the reference plane is perpendicular to the axis of the laundry processing chamber.

[0011] In some embodiments, the detergent dispensing device includes a turbulent flow structure, which is arranged in the second water channel and is used to provide a circumferential velocity component to the fluid in the second water channel.

[0012] In some embodiments, the water outlet end of the first water channel and the water outlet end of the second water channel are respectively used to release fluid into the clothing processing chamber, and the fluid sprayed from the water outlet end of the first water channel can intersect with the fluid sprayed from the water outlet end of the second water channel in the air of the clothing processing chamber.

[0013] In some embodiments, the fluid of the first waterway has a first flow path in the clothing processing chamber, the fluid of the second waterway has a second flow path in the clothing processing chamber, and the first flow path intersects with the second flow path; and / or, the extension direction of the water outlet end of the first waterway intersects with the extension direction of the water outlet end of the second waterway.

[0014] In some embodiments, the clothing processing device includes a barrel assembly and a door sealing ring, the door sealing ring is arranged on the front side of the barrel assembly, the first water channel and the second water channel pass through the door sealing ring, and the water outlet end of the first water channel and the water outlet end of the second water channel are located radially inward of the door sealing ring.

[0015] In some embodiments, the clothing processing device includes a nozzle unit, which is connected to the door seal ring. The nozzle unit includes a shell portion, which is located radially inward of the door seal ring. The shell portion is formed with a mixing space and a water spray port. The fluid of the first water channel and the fluid of the second water channel converge in the mixing space, and the mixed fluid in the mixing space is discharged into the clothing processing chamber through the water spray port.

[0016] In some embodiments, the nozzle unit includes a nozzle, which is arranged inside the mixing space, and the outlet of the nozzle constitutes the water outlet end of the second water channel, and the outlet of the nozzle faces the water spray port.

[0017] In the laundry treatment device provided by the embodiments of the present application, the mixed detergent solution intersects with the fluid in the second water channel before being sprayed onto the laundry to be treated. When the two fluids intersect, they mix and impact, further promoting the dissolution of the detergent and also promoting the foaming of the detergent. Because the intersection is located in the laundry treatment chamber, the distance from the intersection of the mixed fluids in the first and second water channels to the time they are sprayed onto the laundry to be treated can be shortened, reducing the degree of foaming of the foamy detergent, facilitating the delivery of a large amount of foamy detergent to the laundry to be treated, and thereby improving the cleaning effect.

[0018] 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.

[0031] 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.

[0032] 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 and are intended only to facilitate the description of the embodiments of the present application and to simplify the description.

In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] 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. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of this application based on the specific circumstances.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] See also Figure 2 and Figure 3 The detergent dispenser 100 includes 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 water inlet of the first water channel 40A is connected to a water source, and the water inlet of the second water channel 50A is connected to a water source. It can be understood that the fluid in the first water channel 40A and the fluid in the second water channel 50A are ultimately delivered to the laundry processing chamber.

[0039] 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 8 , the dotted lines with arrows in the accompanying drawings indicate the flow direction of the fluid.

[0040] The fluid in the first water channel 40A is a detergent mixed solution.

[0041] 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.

[0042] 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.

[0043] The fluid in the first water channel 40A merges with the fluid in the second water channel 50A, and the merge position is located in the laundry processing chamber.

[0044] In the laundry treatment device of the embodiment of the present application, the mixed detergent solution intersects with the fluid in the second water channel 50A before being sprayed onto the laundry. When the two fluids intersect, they mix and impact, further promoting detergent dissolution and foaming. Because the intersection is located within the laundry treatment chamber, the distance between the mixed fluids in the first water channel 40A and the second water channel 50A and their delivery to the laundry can be shortened, reducing the degree of foaming of the foamy detergent, facilitating the delivery of a larger amount of foamy detergent to the laundry, and thereby improving the cleaning effect.

[0045] 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.

[0046] 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.

[0047] For example, see Figure 1 The first water channel 40A and the second water channel 50A pass through the door sealing ring 60, and the water outlet end of the first water channel 40A and the water outlet end of the second water channel 50A are located on the radial inner side of the door sealing ring 60. This is conducive to the intersection of the fluid in the first water channel 40A and the fluid in the second water channel 50A in the clothing processing chamber, which facilitates improving the design flexibility of the intersection position and intersection angle of the two fluids.

[0048] For example, in some embodiments, see Figure 2 The 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.

[0049] 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.

[0050] Exemplarily, the clothing processing device also includes a water inlet valve 90, which has a first outlet 90a. The first water channel 40A and the second water channel 50A are both connected to the first outlet 90a. The water source supplies water to the first water channel 40A and / or the second water channel 50A through the water inlet valve 90. When the detergent dispensing device 100 dispenses the detergent mixed solution into the clothing processing chamber, it can also assist in water intake and spray the clothes to be treated.

[0051] The above-mentioned intersection position is located in the laundry processing chamber in any embodiment, including but not limited to the following two.

[0052] First, in some embodiments, the outlet of the first water channel 40A and the outlet of the second water channel 50A are each used to deliver fluid into the laundry treatment chamber, and the fluid ejected from the outlet of the first water channel 40A and the fluid ejected from the outlet of the second water channel 50A can intersect in the air of the laundry treatment chamber. In other words, the intersection is exposed in the space of the laundry treatment chamber.

[0053] This embodiment does not require an additional piping structure. The kinetic energy of the fluid at the outlet end of the first water channel 40A and the kinetic energy of the fluid in the second water channel 50A are used to cause the two fluids to collide. On the one hand, the detergent mixed solution can be impacted and mixed, thereby promoting the full dissolution of the detergent. On the other hand, the two fluids can be dispersed after colliding in the air, which can expand the spraying area and improve the spraying effect.

[0054] There is no limit to the way the two fluids meet in mid-air.

[0055] For example, see Figure 9 In some embodiments, the fluid in the first waterway 40A has a first flow path in the clothing treatment chamber, and the fluid in the second waterway 50A has a second flow path in the clothing treatment chamber, and the first flow path and the second flow path intersect. It should be noted that the first flow path refers to the movement path of the fluid after leaving the water outlet of the first waterway 40A, and the second flow path refers to the movement path of the fluid after leaving the water outlet of the second waterway 50A. The first flow path and the second flow path can be straight lines or parabolas, which are not limited here, and the form of the fluid after being ejected can be a water curtain or a water column. It can be understood that when the water column-like fluid hits the water curtain-like fluid, this also belongs to an implementation case where the first flow path and the second flow path intersect.

[0056] For some examples, see Figure 10 The extension direction of the water outlet end of the first water channel 40A (the centerline direction in the figure) intersects with the extension direction of the water outlet end of the second water channel 50A (the centerline direction in the figure). When the fluid ejection velocity is high, the two fluids intersect near the intersection of the above-mentioned extension lines. When the fluid ejection velocity is low, the two fluids intersect below the intersection of the above-mentioned extension lines. In this way, the fluid in the first water channel 40A easily intersects with the fluid in the second water channel 50A in the air of the clothing processing chamber.

[0057] Second, in some embodiments, see Figure 7 and Figure 8The detergent dispensing device 100 also includes a mixing space 20a and a water spray port 201b. The mixing space 20a is located in the clothing processing chamber. The fluid in the first water channel 40A and the fluid in the second water channel 50A converge in the mixing space 20a. The mixed fluid in the mixing space 20a is dispensed into the clothing processing chamber through the water spray port 201b.

[0058] It should be noted that the mixing space 20a is a chamber formed in a physical structure. In this embodiment, 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 be put into the clothing processing chamber.

[0059] In some embodiments, the water spray port 201b is used to spray water obliquely downward toward the rear side of the laundry processing chamber.

[0060] 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.

[0061] The value of the acute angle φ is not limited. For example, the acute angle φ formed by the centerline n of the water jet 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 ejected from the water jet 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 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] For some examples, see Figure 4 The clothes treating device includes a nozzle unit 200, and the nozzle unit 200 is connected to the door seal 60. That is, the door seal 60 provides an installation support for the nozzle unit 200.

[0074] The nozzle unit 200 includes a shell 201, which is located radially inward of the door seal 60. The shell 201 forms a mixing space 20a and a water spray port 201b. The fluid in the first water channel 40A and the fluid in the second water channel 50A converge in the mixing space 20a, and the mixed fluid in the mixing space 20a is discharged into the clothing processing chamber through the water spray port 201b.

[0075] That is, the first water channel 40A and the second water channel 50A are both connected to the nozzle unit 200, and the outlet ends of the first water channel 40A and the second water channel 50A can both deliver fluid into the nozzle unit 200, so that the fluid in the first water channel 40A and the fluid in the second water channel 50A merge in the mixing space 20a and are discharged through the water outlet 201b on the shell 201. The nozzle unit 200 serves to gather the first water channel 40A and the second water channel 50A.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] For some examples, see Figure 7 and Figure 8 A guide channel 201a is formed inside the shell 201, and the guide channel 201a is connected to the mixing space 20a. The end of the guide channel 201a constitutes the water outlet end of the first water channel 40A.

[0084] As a specific implementation, along the flow direction of the fluid, the flow cross-section of the flow guide channel 201a gradually increases.

[0085] 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.

[0086] For some examples, see Figure 7The outlet cross-section of the diversion channel 201a (referenced at position y) is larger than the outlet cross-section of the nozzle 202 (referenced at position x), and smaller than the outlet cross-section of the water outlet port 201b (referenced at position z). 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 risk of fluid in the mixing space 20a flowing back into the first water channel 40A. Furthermore, the outlet cross-section of the first water channel 40A is larger than the outlet cross-section of the second water channel 50A. This allows the detergent mixture to enter the mixing space 20a from the first water channel 40A, creating a greater contact area between the detergent components per unit volume and the fluid in the mixing space 20a. This facilitates more uniform mixing and complete dissolution of the detergent components.

[0087] For some examples, see Figure 4 、 Figure 6 and Figure 7 The first and second joint tubes 204, 205 are arranged along a first direction R, and the housing 201 extends along the first direction R. The orientation of the first direction R is not limited. As an optional embodiment, in some embodiments, the first direction R is substantially tangential to the door seal 60. This facilitates the circumferential spacing of the first and second joint tubes 204, 205 along the door seal 60, saving space along the front-to-back direction of the laundry processing device. It should be noted that the distance between the first and second joint tubes 204, 205 must be sufficient to prevent interference when connecting the pipes.

[0088] The various embodiments / implementations provided in this application can be combined with each other without causing any contradiction.

[0089] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
