[0028] As shown in FIGS. 1 to 15, according to an embodiment of the present application, a laundry treatment device 100 is proposed, which includes a laundry treatment chamber 11 and a delivery assembly 20.
[0029] Specifically, the laundry treatment chamber 11 is configured to hold laundries to be treated, and the delivery assembly 20 includes a first nozzle 201, a detergent cartridge assembly 207, and a mixing assembly 208. The first nozzle 201 includes an atomizing structure and communicates with the laundry treatment chamber 11, and the mixing assembly 208 communicates with the first nozzle 201, a water supply pipeline and the detergent cartridge assembly 207. The mixing assembly 208 receives detergent and clean water, mixes the received clean water and detergent, and then delivers the mixed solution into the laundry treatment chamber 11 through the first nozzle 201.
[0030] When the laundries are washed, the detergent is injected into the mixing assembly 208 from the detergent cartridge assembly 207, the clean water is injected into the mixing assembly 208 from the water supply pipeline, and the detergent and the clean water form a mixed solution in the mixing assembly 208. The mixed solution is delivered into the laundry treatment chamber 11 through the first nozzle 201 to treat the laundries through the mixed solution. The mixing assembly 208 is provided to make the mixed solution formed by the detergent and the water more uniform. The first nozzle 201 is provided with the atomizing structure, so that the area of the mixed solution delivered into the laundry treatment chamber 11 through the first nozzle 201 is larger, thereby improving the uniformity of spraying the detergent on the laundries, and further improving the cleaning effect of the laundries.
[0031] It should be understood that after the detergent and the clean water are respectively injected into the mixing assembly 208, the detergent and the clean water flow in the mixing assembly 208 respectively. The mixing assembly 208 provides a space for mixing the clean water and the detergent, so that the clean water and the detergent can be fully mixed during the flow process to form a mixed solution, thereby improving the uniformity of the mixed solution, and further effectively improving the uniformity of the mixed solution delivered into the laundry treatment chamber 11 through the first nozzle. The mixed solution with high uniformity can improve the washing effect on the laundries.
[0032] In the related art, the mixed solution is injected into the laundry treatment chamber 11 by an ordinary nozzle, and the mixed solution injected by the ordinary nozzle is in the form of a jet, and the coverage area thereof is small. In the present application, the first nozzle 201 is provided with the atomizing structure, so that the first nozzle 201 forms an atomizing nozzle. In the process that the mixed solution is sprayed into the laundry treatment chamber 11 through the atomizing nozzle, the atomizing nozzle can deliver the mixed solution in the form of a mist (small droplets or small bubbles, etc.). Compared with the mixed solution in the form of the jet, the mixed solution in the form of the mist allows the coverage area thereof in the laundry treatment chamber 11 to be increased, which increases the contact area between the volume of the detergent and the laundries, thereby improving the washing effect of the detergent on the laundries.
[0033] It should be noted that, in order to meet different needs in the laundry washing process, the types of detergents include but are not limited to softeners, liquid detergents, laundry powders, disinfectants, etc. Therefore, a plurality of liquid storage spaces are provided in a cartridge body, and one detergent can be stored in each liquid storage space, to meet the needs of using a plurality of detergents in the laundry treatment process. In addition, the liquid storage space and the cartridge body may be an integrated structure, that is, a plurality of independent spaces are formed inside the cartridge body. The plurality of liquid storage spaces can be formed in a plurality of liquid storage cartridges, that is, a plurality of mounting positions are provided in the cartridge body, and each liquid storage cartridge is detachably mounted on a respective one of the plurality of mounting positions, each liquid storage cartridge stores a detergent, and the detergent can be replenished by replacing the liquid storage cartridge.
[0034] Furthermore, in the present application, the mixing assembly 208 is provided as a mixer. The mixer and the detergent cartridge assembly 207 may be separable structures, and may communicate with each other by a pipeline. The mixer may also be integrated inside the detergent cartridge assembly 207 or on an outer casing of the detergent cartridge assembly 207.
[0035] As shown in FIG. 1, the laundry treatment device 100 includes a box body, a laundry treatment drum 10, a door body, and a door seal 30. The laundry treatment drum 10 is arranged in the box body, and a pick-up port is arranged on the box body and opposite to an opening of the laundry treatment drum 10. The door seal 30 is arranged between the pick-up port and the opening to close a space between the pick-up port and the opening. The door body is pivotally connected to the box body, and the pick-up port is opened or closed through the rotation of the door body relative to the box body. When the pick-up port is closed, the laundry treatment device 100 may perform a laundry treatment action (for example, washing the laundries or the like). When the pick-up port is opened, the user can take out or put the laundries through the pick-up port.
[0036] In addition, the laundry treatment drum 10 includes an inner drum and an outer drum, the outer drum is installed and fixed in the box body, and the inner drum is arranged inside the outer drum and is rotatable relative to the outer drum. The laundry treatment chamber 11 is formed in the inner drum, and an opening of the inner drum and an opening of the outer drum are arranged coaxially, and form the opening of the laundry treatment drum 10. The inner drum is connected to a driving member (a driving motor) of the laundry treatment device 100. The driving member drives the inner drum to rotate, to realize the turning of the laundries and improve the treatment effect of the laundries.
[0037] In the present application, the first nozzle 201 is installed on the door seal 30, and a delivery direction of the first nozzle 201 faces toward the laundry treatment chamber 11, so that the first nozzle 201 can effectively deliver the mixed solution into the laundry treatment chamber 11.
[0038] In some embodiments of the present application, as shown in FIGS. 12 to 15, the mixing assembly 208 includes a mixing chamber 20814, a liquid outlet 20811, and two liquid inlets, and the two liquid inlets are a first liquid inlet 20812 and a second liquid inlet respectively. The mixing chamber 20814 communicates with the first liquid inlet 20812, the second liquid inlet and the liquid outlet 20811 respectively, the detergent cartridge assembly 207 communicates with the first liquid inlet 20812, the water supply pipeline communicates with the second liquid inlet, and the first nozzle 201 communicates with the liquid outlet 20811,
[0039] Specifically, as shown in FIG. 15, the mixing chamber 20814 is formed inside the mixing assembly 208, the first liquid inlet 20812, the second liquid inlet, and the liquid outlet 20811 are formed on an outer surface of the mixing assembly 208, and the first liquid inlet 20812, the second liquid inlet, and the liquid outlet 20811 are arranged spaced apart from each other on the outer surface of the mixing assembly 208. When the mixing assembly 208 is in use, the detergent cartridge assembly 207 injects the detergent into the mixing chamber 20814 through the first liquid inlet 20812, the water supply pipeline injects the clean water into the mixing chamber 20814 through the second liquid inlet, the clean water and the detergent are mixed in the mixing chamber 20814 to form a mixed solution, and the mixed solution is delivered into the laundry treatment chamber 11 through the liquid outlet 20811 and the first nozzle 201. The first liquid inlet 20812 and the second liquid inlet are arranged spaced apart from each other on the surface of the mixing assembly 208, so that the clean water and the detergent entering the mixing chamber 20814 are spaced apart from each other, thereby reducing the resistance generated by the purified water and the detergent entering the mixing chamber 20814, and improving the smoothness of the purified water and the detergent.
[0040] It should be understood that the mixing chamber 20814 is a relatively closed chamber structure. The first liquid inlet 20812 and the second liquid inlet are located upstream of the mixing chamber 20814, and the liquid outlet 20811 is located downstream of the mixing chamber 20814. The mixing chamber 20814 has a certain length between the liquid outlet 20811 and the liquid inlets (the first liquid inlet 20812 and the second liquid inlet). When the clean water and the detergent are injected into the mixing chamber 20814, both the clean water and the detergent flow from upstream to downstream of the mixing chamber 20814. The clean water and the detergent are mixed with each other during the flow process and can be further mixed fully with the flow and form a mixed solution. The fully mixed solution is sprayed into the laundry treatment chamber 11 through the liquid outlet 20811 and the first nozzle 201.
[0041] It should be noted that, as shown in FIG. 15, the mixing assembly 208 is provided with a first joint at the position of the first liquid inlet 20812, a second joint at the position of the second liquid inlet, and a third joint at the position of the liquid outlet 20811.
[0042] The first joint communicates with the detergent cartridge assembly 207 through a first connecting pipe, a connection manner between the first joint and the first connecting pipe is sleeve connection, and a first anti-detachment structure (such as an annular projection or the like) is provided on an outer peripheral surface of the first joint, to improve the strength of the connecting position. A first hoop or the like is provided at the connecting position of the first connecting pipe and the first joint to further improve the connecting strength between the first connecting pipe and the first joint.
[0043] The second joint communicates with the water supply pipeline through a second connecting pipe, the connection manner between the second joint and the second connecting pipe is sleeve connection, and a second anti-detachment structure (such as an annular projection or the like) is provided on an outer peripheral surface of the second joint, to improve the strength of the connection position. A second hoop or the like is provided at the connection position of the second connecting pipe and the second joint to further improve the connection strength between the second connecting pipe and the second joint.
[0044] The third joint communicates with the first nozzle 201 through a third connecting pipe, the connection manner between the third joint and the third connecting pipe is sleeve connection, and a third anti-detachment structure (for example, an annular projection or the like) is provided on an outer peripheral surface of the third joint, to improve the strength of the connection position. A third hoop or the like is provided at the connection position of the third connecting pipe and the third joint to further improve the connection strength between the third connecting pipe and the third joint.
[0045] Further, the mixing assembly 208 may be a metal component or a non-metal component. When the mixing assembly 208 is a metal component, for example, when the mixing assembly 208 is an aluminum component, the mixing assembly 208 can be manufactured by casting or the like. When the mixing assembly 208 is a non-metallic component, for example, when the mixing assembly 208 is a plastic component, the mixing assembly 208 can be manufactured by injection molding.
[0046] In addition, the members of the mixing assembly 208 may be manufactured in one piece or may be manufactured separately and then assembled together. In the present application, the members of the mixing assembly 208 are manufactured separately and then assembled together, thereby improving the convenience and efficiency of manufacturing. The mixing assembly 208 includes a main body 2081 and a lid 2082. The main body 2081 is provided with the first liquid inlet 20812, the second liquid inlet, the liquid outlet 20811, and the mixing chamber 20814 provided with an opening. The lid 2082 is fixedly connected (bonded, welded, screwed, etc.) to the main body 2081, and closes the opening of the mixing chamber 20814. The members of the mixing assembly 208 are manufactured separately, which improves the convenience of manufacturing.
[0047] In some embodiments of the present application, as shown in FIGS. 14 to 15, the mixing chamber 20814 is provided with a first end and a second end, and the first end and the second end are disposed opposite to each other. The mixing chamber 20814 and the first liquid inlet 20812 have a first communication position, and the mixing chamber 20814 and the liquid outlet 20811 have a second communication position. A distance between the first communication position and the second end is greater than a distance between the first communication position and the first end, that is, the first communication position is arranged close to the first end. A distance between the second communication position and the first end is greater than a distance between the second communication position and the second end, that is, the second communication position is arranged close to the second end. The first liquid inlet 20812 is located between the liquid outlet 20811 and the second liquid inlet.
[0048] Specifically, when the mixing assembly 208 is in use, the detergent in the detergent cartridge assembly 207 is injected into the mixing chamber 20814 through the first liquid inlet 20812 and flows toward the liquid outlet 20811, the water supply pipeline is opened, and the clean water in the water supply pipeline is injected into the mixing chamber 20814 through the second liquid inlet and flows toward the liquid outlet 20811. When the clean water flows through the first liquid inlet, the clean water and the detergent are mixed to form a mixed solution. In the process that the mixed solution flows toward the liquid outlet 20811, the detergent and the clean water are further mixed to make the mixed solution more uniform, which improves the uniformity of the mixed solution, thereby effectively improving the treatment effect of the mixed solution on the laundries.
[0049] It should be understood that the first liquid inlet 20812 is arranged between the liquid outlet 20811 and the second liquid inlet, and the clean water flows from the second liquid inlet to the liquid outlet 20811, so that the mixing chamber 20814 can be washed by the clean water, thereby reducing the situation of residual detergent in the mixing chamber 20814.
[0050] In some embodiments of the present application, in the mixing chamber 20814, a direction from the first end to the second end opposite to the first end is defined as a axial direction of the mixing chamber 20814. In the axial direction of the mixing chamber 20814, the first liquid inlet 20812 is arranged between the second liquid inlet and the liquid outlet 20811, a distance between the liquid outlet 20811 and the first liquid inlet 20812 is a first distance, and a distance between the second liquid inlet and the first liquid inlet 20812 is a second distance, in which the second distance is less than the first distance.
[0051] By setting the first distance and the second distance, the first liquid inlet 20812 arranged between the liquid outlet 20811 and the second liquid inlet is arranged closer to the second liquid inlet. When the mixing assembly 208 is in use, the clean water enters the mixing chamber 20814 from the second liquid inlet, and the detergent enters the mixing chamber 20814 from the first liquid inlet 20812. Since the first liquid inlet 20812 and the second liquid inlet are arranged close to each other, the clean water and the detergent entering the mixing chamber 20814 can be quickly mixed to form a mixed solution. The formed mixed solution is mixed again in the process that it flows to the liquid outlet 20811 along the mixing chamber 20814. In this way, the uniformity of mixing the clean water and the detergent is improved, and the uniformity of the mixed solution entering the laundry treatment chamber 11 through the liquid outlet 20811 and the first nozzle 201 can be further improved, so that the washing effect on the laundries can be further improved.
[0052] In some embodiments of the present application, in case that the first liquid inlet 20812 is arranged tangentially to the flow cross section of the mixing chamber 20814, when the detergent in the detergent cartridge assembly 207 is injected into the mixing chamber 20814 through the first liquid inlet 20812, the detergent has a component velocity in a circumferential direction of the mixing chamber 20814. In this way, the detergent has a plurality of flow directions in the mixing chamber 20814, which increases the chance of contact with the clean water, and further improves the mixing uniformity of the detergent and the clean water. In addition, an inlet direction of the first liquid inlet 20812 is disposed at an acute angle with respect to the axial direction of the mixing chamber 20814, and the first liquid inlet 20812 is inclined toward a side of the second liquid inlet, so that the detergent entering the mixing chamber 20814 through the first liquid inlet 20812 has a component velocity from the first end to the second end of the mixing chamber 20814 at the same time.
[0053] In some embodiments of the present application, in case that the second liquid inlet is arranged tangentially to the flow cross section of the mixing chamber 20814 (the two tangent directions are opposite to each other), when the detergent in the detergent cartridge assembly 207 is injected into the mixing chamber 20814 through the first liquid inlet 20812 and the clean water in the water supply pipeline is injected into the mixing chamber 20814 through the second liquid inlet, each of the detergent and the clean water has a component velocity in the circumferential direction of the mixing chamber 20814. In this way, the clean water and the detergent have a plurality of flow directions in the mixing chamber 20814, which increases the chance of contact with the detergent, and further improves the mixing uniformity of the detergent and the clean water. In addition, an inlet direction of the second liquid inlet is disposed at an acute angle with respect to the axial direction of the mixing chamber 20814, and the second liquid inlet is inclined toward a side away from the first liquid inlet 20812, so that the clean water entering the mixing chamber 20814 through the second liquid inlet has a component velocity from the first end to the second end of the mixing chamber 20814 at the same time.
[0054] In some embodiments of the present application, in case that each of the first liquid inlet 20812 and the second liquid inlet is arranged tangentially to the flow cross section of the mixing chamber 20814, when the clean water in the water supply pipeline is injected into the mixing chamber 20814 through the second liquid inlet, the clean water has a component velocity in a circumferential direction of the mixing chamber 20814. In this way, the clean water has a plurality of flow directions in the mixing chamber 20814, which increases the chance of contact with the detergent, and further improves the mixing uniformity of the detergent and the clean water. In addition, an inlet direction of the first liquid inlet 20812 is disposed at an acute angle with respect to the axial direction of the mixing chamber 20814, and the first liquid inlet 20812 is inclined toward a side of the second liquid inlet, so that the detergent entering the mixing chamber 20814 through the first liquid inlet 20812 has a component velocity from the first end to the second end of the mixing chamber 20814 at the same time. An inlet direction of the second liquid inlet is disposed at an acute angle with respect to the axial direction of the mixing chamber 20814, and the second liquid inlet is inclined toward a side away from the first liquid inlet 20812, so that the clean water entering the mixing chamber 20814 through the second liquid inlet has a component velocity from the first end to the second end of the mixing chamber 20814 at the same time.
[0055] In some embodiments of the present application, as shown in FIG. 15, the mixing chamber 20814 is a circular truncated cone structure, the first end and the second end are two ends of the mixing chamber 20814 in the axial direction, the flow cross section of the second end is less than the flow cross section of the first end, and the liquid outlet 20811 is located at the second end and disposed coaxially with the mixing chamber 20814.
[0056] Specifically, when the mixing assembly 208 is in use, the detergent in the detergent cartridge assembly 207 is injected into the mixing chamber 20814 through the first liquid inlet 20812, the clean water in the water supply pipeline is injected into the mixing chamber 20814 only through the second liquid inlet, and the clean water and the detergent entering the mixing chamber 20814 flow from the first end to the second end, and are mixed during the flow process to form a mixed solution. The liquid outlet 20811 is provided at the second end, and the second end is provided so that the flow area of the second end is less than the flow area of the first end. In this way, the mixed solution is in a compressed state during the flow of the mixed solution to the second end, which thus can improve the uniformity of mixing of the detergent, and can further improve the uniformity of the mixed solution.
[0057] It should be understood that the mixing chamber 20814 is a circular truncated cone structure, and the flow cross section of the second end is less than the flow cross section of the first end. In this way, the mixed solution can be compressed by the structural dwindling, so that the flow velocity of the mixed solution can be increased, and the output efficiency of the mixed solution can be improved.
[0058] In some embodiments of the present application, the mixing chamber 20814 is a conical structure, the first end and the second end are two ends of the mixing chamber 20814 in the axial direction, the flow cross section of the second end is less than the flow cross section of the first end, and the liquid outlet 20811 is located at the second end and disposed coaxially with the mixing chamber 20814.
[0059] Specifically, when the mixing assembly 208 is in use, the detergent in the detergent cartridge assembly 207 is injected into the mixing chamber 20814 through the first liquid inlet 20812, the clean water in the water supply pipeline is injected into the mixing chamber 20814 only through the second liquid inlet, and the clean water and the detergent entering the mixing chamber 20814 flow from the first end to the second end, and are mixed during the flow process to form a mixed solution. The liquid outlet 20811 is provided at the second end, and the second end is provided so that the flow area of the second end is less than the flow area of the first end. In this way, the mixed solution is in a compressed state during the flow of the mixed solution to the second end, which thus can further improve the uniformity of mixing of the detergent, and can further improve the uniformity of the mixed solution.
[0060] It should be understood that the mixing chamber 20814 is a conical structure, and the flow cross section of the second end is less than the flow cross section of the first end. In this way, the mixed solution can be compressed by the structural dwindling, so that the flow velocity of the mixed solution can be increased, and the output efficiency of the mixed solution can be improved.
[0061] In some embodiments of the present application, the mixing chamber 20814 is a columnar structure, the first end and the second end are two ends of the mixing chamber 20814 in the axial direction, the liquid outlet 20811 is located at the second end and disposed coaxially with the mixing chamber 20814, and the area of the mixing chamber 20814 at the second end is greater than the area of the liquid outlet 20811. A flow guide structure is provided between a side wall of the mixing chamber 20814 and the second end, and is configured to guide the mixed liquid in the mixing chamber 20814 to the liquid outlet 20811.
[0062] Specifically, the flow guide structure is formed on an inner wall of the mixing chamber 20814 and is a conical surface, the shape of the mixing chamber 20814 between the flow guide structure and the second end is a circular truncated cone structure, the shape of the mixing chamber 20814 between the flow guide structure and the first end is a cylindrical structure, and the mixing chamber 20814 with the flow guide structure is a combined structure formed by the circular truncated cone structure and the cylindrical structure. The structure of the mixing chamber 20814 can be larger in volume than the mixing chamber 20814 with a conical structure and the mixing chamber 20814 with a circular truncated cone structure, thereby improving the mixing capacity of the detergent, and thus effectively satisfying the demand of the laundry treatment chamber 11 for the mixed solution.
[0063] It should be noted that in the axial direction of the mixing chamber 20814, the dimension of the cylindrical structure is greater than the dimension of the circular truncated cone structure, so that the volume of the mixing chamber 20814 can be increased.
[0064] In some embodiments of the present application, as shown in FIGS. 4 to 11, the first nozzle 201 is provided with a discharge port 2012, an inlet port 2011, and a fluid channel 2015, the fluid channel 2015 communicates with the inlet port 2011 and the discharge port 2012 respectively, the liquid outlet 20811 communicates with the inlet port 2011, and the laundry treatment chamber 11 communicates with the discharge port 2012.
[0065] Specifically, the inlet port 2011 of the first nozzle 201 communicates with the liquid outlet 20811 of the mixing assembly 208, and the discharge port 2012 of the first nozzle 201 communicates with the laundry treatment chamber 11.
[0066] When it is necessary to deliver the mixed solution into the laundry treatment chamber 11, the detergent cartridge assembly 207 injects the detergent into the mixing chamber 20814 of the mixing assembly 208, and at the same time, the water supply pipeline also injects the clean water into the mixing chamber 20814 of the mixing assembly 208. The clean water and the detergent are mixed in the mixing chamber 20814 to form a mixed solution, and the mixed solution flows toward the liquid outlet 20811. The detergent and the clean water in the mixed solution are fully mixed, then enter the fluid channel 2015 of the first nozzle 201 through the liquid outlet 20811 and the inlet port 2011 of the first nozzle 201, and then is delivered into the laundry treatment chamber 11 through the discharge port 2012 of the first nozzle 201, so that the mixed solution is delivered into the laundry treatment chamber 11 to meet the laundry washing demand.
[0067] When it is necessary to deliver the clean water into the laundry treatment chamber 11, the detergent cartridge assembly 207 stops running, to stop the injecting of the detergent into the mixing chamber 20814. The water supply pipeline injects the clean water into the mixing chamber 20814 of the mixing assembly 208. The clean water flows toward the liquid outlet 20811, enters the fluid channel 2015 of the first nozzle 201 through the liquid outlet 20811 and the inlet port 2011 of the first nozzle 201, and is then delivered into the laundry treatment chamber 11 through the discharge port 2012 of the first nozzle 201, so that the clean water is delivered into the laundry treatment chamber 11 to meet the laundry washing demand.
[0068] It should be noted that the discharge port 2012 may be a circular port, a square port (the corner position is transitioned through an arc), a flat port (the corner position is transitioned through an arc), a diamond port, an elliptical port, or the like.
[0069] Further, the number of discharge ports 2012 may be one, two, three, four, five, or the like. By providing a plurality of discharge ports 2012, it is possible to increase the amount of the fluid to be delivered, and it is possible to further improve the sufficiency of contact between the laundries and the fluid, so that the treatment effect of the laundries is further improved. When there is a plurality of (two or more) discharge ports 2012, delivery directions of the plurality of discharge ports 2012 may be the same, partially the same, or completely different. Further, when there is a plurality of (two or more) discharge ports 2012, the plurality of discharge ports 2012 may overlap with each other, partially overlap with each other, or be misaligned with each other along a circumferential direction of the first nozzle 201.
[0070] In some embodiments of the present application, as shown in FIG. 11, a flow disturbing structure 2018 is provided in the fluid channel 2015 of the first nozzle 201,
[0071] Specifically, the flow disturbing structure 2018 is provided in the fluid channel 2015 of the first nozzle 201. When the fluid (the mixed solution or clean water) output from the mixing assembly 208 enters the fluid channel 2015 of the first nozzle 201, the fluid is discharged from the inlet port 2011 to the discharge port 2012. When the fluid passes through the flow disturbing structure 2018, the flow disturbing structure 2018 disturbs the fluid, so that the fluid has a component velocity in the circumferential direction of the fluid channel 2015, and at this time, the fluid also has a component velocity in the axial direction of the fluid channel 2015. When the fluid with a component velocity in each of the circumferential direction and the axial direction of the fluid channel 2015 is ejected through the discharge port 2012 of the first nozzle 201, a mist-like structure can be formed, so that the coverage area of the nozzle in the laundry treatment chamber 11 can be increased, and the laundries can be sufficiently in contact with the fluid, thereby improving the treatment effect of the laundries.
[0072] It should be understood that when there is no flow disturbing structure 2018 in the fluid channel 2015, the fluid only has a velocity in the axial direction of the fluid channel 2015. At this time, when the fluid is ejected through the discharge port 2012, a jet will be formed, the coverage area of the jet in the laundry treatment chamber 11 is small, and the laundries cannot be fully in contact with the fluid, which will lead to a poor treatment effect on the laundries.
[0073] It should be noted that the flow disturbing structure 2018 is provided in the fluid channel 2015 of the first nozzle 201, and the flow disturbing structure 2018 may be integrally molded with the first nozzle 201, or may be assembled into the fluid channel 2015 of the first nozzle 201 by assembling.
[0074] The flow disturbing structure 2018 includes, but is not limited to, a swirl plate, a swirl rib, a flow disturbing column, a flow disturbing plate with a via, and the like. In some embodiments of the present application, the flow disturbing structure 2018 is a swirl plate, there are two swirl plates fixedly connected to an inner wall of the fluid channel 2015, and the two swirl plates are arranged facing toward each other. The swirl plates are inclined in the axial direction of the fluid channel 2015, and the inclined directions of the two swirl plates are opposite to each other. A channel formed between the two swirl plates is a swirl channel. When the fluid passes through the two swirl plates, the fluid collides with the two swirl plates, and the collided fluid has a component velocity in each of the axial direction and the circumferential direction of the fluid channel 2015.
[0075] In some embodiments of the present application, the fluid channel 2015 includes a first portion 20151 and a second portion 20152, and the first portion 20151 and the second portion 20152 are connected to each other. The inlet port 2011 communicates with the first portion 20151, the discharge port 2012 communicates with the second portion 20152, the flow disturbing structure 2018 is provided in the first portion 20151, and the flow cross section of at least a part of the first portion 20151 has a gradually dwindling structure in a direction from the first portion 20151 to the second portion 20152.
[0076] Specifically, when the fluid in the mixing assembly 208 enters the fluid channel 2015 from the inlet port 2011 of the first nozzle 201, the fluid first enters the first portion 20151 of the fluid channel 2015, flows along the first portion 20151 to the second portion 20152, and is disturbed by the flow disturbing structure 2018 during the flow process. In this way, the fluid has a component velocity in each of the circumferential direction and the axial direction of the fluid channel 2015, so that the fluid sprayed through the second portion 20152 and the discharge port 2012 is in the form of a mist, thereby increasing the coverage area of the fluid in the laundry treatment chamber 11. Since the flow cross section of at least a part of the first portion 20151 has a gradually dwindling structure in the direction from the first portion 20151 to the second portion 20152, when the fluid passes through the gradually dwindling structure, the gradually dwindling structure compresses the fluid to allow the velocity of the fluid to be increased, so that the fluid flowing out of the second portion 20152 and being delivered into the laundry treatment chamber 11 through the discharge port 2012 has a higher delivery velocity, further increasing the delivery region of the fluid in the laundry treatment chamber 11.
[0077] It should be noted that the flow disturbing structure 2018 is disposed inside the first portion 20151, and the flow disturbing structure 2018 is located between two ends of the first portion 20151 (in which one end is an inlet of the first nozzle 201, and another end is a communication position of the first portion 20151 and the second portion 20152).
[0078] In some embodiments of the present application, as shown in FIG. 11, the fluid channel 2015 further includes a third portion 20153, the discharge port 2012 communicates with the second portion 20152 through the third portion 20153, the third portion 20153 has a flow cross section, and the flow cross section of the third portion 20153 is a gradually expanding structure in a direction from the second portion 20152 to the third portion 20153.
[0079] Specifically, the fluid channel 2015 of the first nozzle 201 includes a first portion 20151, a second portion 20152, and a third portion 20153 which sequentially communicate with each other. A flow disturbing structure 2018 is provided in the first portion 20151, and the first portion 20151 communicates with the inlet port 2011. The third portion 20153 communicates with the discharge port. In a direction from the first portion 20151 to the third portion 20153, the flow cross section of a part of the first portion 20151 has a gradually dwindling structure, and the third portion 20153 has a gradually expanding structure. When the fluid in the mixing assembly 208 enters the fluid channel 2015 through the inlet port 2011 of the first nozzle 201, the fluid firstly passes through the first portion 20151 during the flow process, and is disturbed by the flow disturbing structure 2018, so that the fluid has a component velocity in each of the axial direction and the circumferential direction of the fluid channel 2015. The fluid is compressed by the gradually dwindling structure of the first portion 20151 to increase the flow velocity of the fluid. After the fluid passing through the first portion 20151 enters the third portion 20153 through the second portion 20152, the gradually expanding structure of the third portion 20153 releases the compressed fluid, so that the fluid can have a wider delivery range, thereby improving the coverage range of the fluid delivered by the first nozzle in the laundry treatment chamber 11, and improving the treatment effect of the laundries.
[0080] In some embodiments of the present application, as shown in FIG. 11, the fluid channel 2015 of the first nozzle 201 includes a first portion 20151, a second portion 20152, and a third portion 20153 which sequentially communicate with each other. The second portion 20152 and the first portion 20151 are disposed coaxially, and the second portion 20152 and the third portion 20153 are disposed at an angle.
[0081] Specifically, in the present application, the first nozzle 201 is an L-shaped structure, the first portion 20151 and the second portion 20152 are located on a side of the L-shaped structure, and the third portion 20153 is located on another side of the L-shaped structure, so that the second portion 20152 and the third portion 20153 are disposed at an angle. By disposing the first nozzle 201, the discharge port 2012 of the first nozzle 201 can be better disposed toward the laundry treatment chamber 11, thereby increasing the coverage area of the first nozzle 201 in the laundry treatment chamber 11, and further improving the treatment effect of the laundries.
[0082] It should be noted that an angle between the second portion 20152 and the third portion 20153 is a, where 0 ° < a < 180 °. In particular, the angle a may be 10 °, 20 °, 30 °, 40 °, 50 °, 60 °, 70 °, 80 °, 90 °, 100 °, 110 °, 120 °, 130 °, 140 °, 150 °, 160 °, or 170 °, etc.
[0083] In addition, the flow cross-sections of the first portion 20151, the second portion 20152, and the third portion 20153 are circular, thereby reducing the resistance of the fluid in the fluid channel 2015 and increasing the flow velocity of the fluid.
[0084] In some embodiments of the present application, as shown in FIGS. 8 to 11, the fluid channel 2015 of the first nozzle 201 includes a first portion 20151, a second portion 20152, and a third portion 20153 which sequentially communicate with each other, an air inlet 2017 communicating with the second portion 20152 is arranged on the first nozzle 201, and external air can enter the second portion 20152 through the air inlet 2017.
[0085] Specifically, the first portion 20151, the second portion 20152, and the third portion 20153 sequentially communicate with each other. The first portion 20151 communicates with the inlet port 2011 of the first nozzle 201, and the third portion 20153 communicates with the discharge port 2012 of the first nozzle 201. In the direction from the first portion 20151 to the third portion 20153, the flow cross section of the first portion 20151 is a gradually dwindling structure, and the flow cross section of the third portion 20153 is a gradually expanding structure. The second portion 20152 is arranged between the first portion 20151 and the third portion 20153 for connecting the first portion 20151 and the third portion 20153, and communicates with the outside world through the air inlet 2017, so that the first nozzle 201 forms a "venture" structure. The fluid enters the first portion 20151 through the inlet port 2011, and flows along the first portion 20151 to the second portion 20152. The first portion 20151 compresses the fluid to accelerate the flow velocity of the fluid. When the accelerated fluid passes through the second portion 20152, a negative pressure is generated at the communication position of the air inlet 2017 and the second portion 20152, external air is sucked into the second portion 20152 from the air inlet 2017 under the action of the negative pressure and mixed with the fluid, and the fluid mixed with the air enters the third portion 20153. After the fluid mixed with the air enters the third portion 20153, since the flow cross section of the third portion 20153 is a gradually expanding structure, the velocity of the fluid mixed with the air is reduced. The fluid mixed with the air having the reduced velocity is sprayed out from the discharge port 2012, and the sprayed fluid mixed with the air is in the form of uniform fine foam. The uniform fine foam is uniformly sprayed into the laundry treatment chamber 11, which increases the contact area with the laundries, thereby improving the treatment effect of the laundries.
[0086] It is to be understood that the fluid describe above may be clean water or a mixed solution. When the fluid is clean water, air is mixed into the clean water to form fine foam, which can improve the rinsing effect of the clean water on the laundries, thereby achieving the effect of saving water and shortening the rinsing time. When the fluid is a mixed solution, air is mixed into the mixed solution to form fine foam, which can improve the decontamination effect of the mixed solution on the laundries, thereby achieving the purpose of improving the washing effect.
[0087] It should be pointed out that, as shown in FIGS. 8 to 11, a first limit structure 2013 (for example, a first convex ring, etc.), a second limit structure 2014 (for example, a second convex ring, etc.), and a third limit structure 2016 (for example, a third convex ring, etc.) are provided on an outer surface of the first nozzle 201. One of the second limit structure 2014 and the third limit structure 2016 is located on one of two opposite sides of the first limit structure 2013, and another one of the second limit structure 2014 and the third limit structure 2016 is located on another one of the two opposite sides of the first limit structure 2013. The second limit structure 2014 is located on a side of the inlet port 2011 of the first nozzle 201. One of the third limit structure 2016 and the discharge port 2012 is located on one of two opposite sides of the air inlet 2017, and another one of the third limit structure 2016 and the discharge port 2012 is located on another one of the two opposite sides of the air inlet 2017.
[0088] A mounting hole is provided on the door seal 30 of the laundry treatment device 100. When the first nozzle 201 is assembled, a part of the body of the first nozzle 201 is arranged in the mounting hole, the second limit structure 2014 is located at the outer side of the door seal 30 and is snap-fitted with a pipeline (a pipeline communicating with the liquid outlet 20811 of the mixing assembly 208), the third limit structure 2016 is located at the inner side of the door seal 30, one of the first limit structure 2013 and the third limit structure 2016 abuts against one of two opposite sides of the door seal 30, and another one of the first limit structure 2013 and the third limit structure 2016 abuts against another one of the two opposite sides of the door seal 30. The installation of the first nozzle 201 is realized by the limit of the first limit structure 2013 and the second limit structure 2014, thereby improving the convenience of assembling. After the assembling of the first nozzle 201 is completed, the air inlet 2017 is located at the inner side of the door seal, thereby reducing the overflow of the fluid to the outer side of the laundry treatment device 100 due to the leakage of the fluid from the air inlet 2017.
[0089] Further, as shown in FIG. 11, a communication chamber 2019 is provided in the first nozzle 201, and the communication chamber 2019 includes a first communication portion and a second communication portion. The second portion 20152, the first communication portion, the second communication portion, and the air inlet 2017 sequentially communicate with each other. In the axial direction of the second portion 20152, the dimension L1 of the first communication portion is less than the dimension L2 of the second communication portion, is less than the dimension L3 of the air inlet 2017, and is less than the dimension L4 of the second pipe section.
[0090] Specifically, in the axial direction of the second portion 20152, the air inlet 2017, the second communication portion, and the first communication portion is in the form of a structure in which the dimensions thereof decrease sequentially, so that it is possible to reduce the occurrence of fluid leakage in the second portion 20152 from the air inlet 2017, and thus, it is possible to smoothly perform the laundry treatment.
[0091] It should be pointed out that in the axial direction of the second portion 20152, the first communication portion and the second communication portion is an L-shaped structure. The communication chamber 2019 in the form of the L-shaped structure can increase the complexity of the path, and can further reduce the fluid leakage of the second portion 20152 from the air inlet 2017 while realizing the suction of the air into the second portion 20152.
[0092] In addition, in the circumferential direction of the second portion 20152, the first communication portion is a first arc-shaped chamber, the second communication portion is a second arc-shaped chamber, and the flow cross section of the second communication portion is equal to the flow cross section of the air inlet. In this way, the second portion 20152 can receive sufficient air supply, which can increase the air content in the mixed solution, so that the delivered fluid can be presented as more fine and uniform foam.
[0093] In some embodiments of the present application, as shown in FIGS. 12 and 13, the delivery assembly 20 further includes a suction pump 211, and the mixing assembly 208 communicates with the detergent cartridge assembly 207 through the suction pump 211.
[0094] Specifically, an inlet of the suction pump 211 communicates with the detergent cartridge assembly 207, and an outlet of the suction pump 211 communicates with the first liquid inlet 20812 of the mixing assembly 208. When the detergent needs to be supplied, the suction pump 211 operates, so that the detergent in the detergent cartridge assembly 207 is sucked into the mixing chamber 20814 of the mixing assembly 208, and mixed with the clean water to form a mixed solution, and then the mixed solution is delivered into the laundry treatment chamber 11 through the liquid outlet 20811 and the first nozzle 201, to meet the laundry treatment demands. The arrangement of the suction pump 211 can facilitate effective injection of the detergent into the mixing assembly 208, thereby improving the mixing efficiency of the detergent.
[0095] In the present application, the suction pump 211 may be a variable frequency pump, a peristaltic pump, or the like.
[0096] In addition, the suction pump 211 may communicate with the detergent cartridge assembly 207 through a pipeline, or the suction pump 211 may also cooperate with the detergent cartridge assembly 207 in an insert connecting manner.
[0097] In some embodiments of the present application, as shown in FIG. 12 and FIG. 13, the delivery assembly 20 further includes a control valve 209, and the second liquid inlet communicates with the water supply pipeline through the control valve 209.
[0098] Specifically, the control valve 209 communicates the water supply pipeline with the mixing assembly 208, in which the second liquid inlet of the mixing assembly 208 is connected to the control valve 209. When the clean water needs to be injected into the mixing chamber 20814 of the mixing assembly 208, the control valve 209 is opened, and under the action of water pressure, the clean water in the water supply pipeline enters the mixing chamber 20814 of the mixing assembly 208 through the control valve 209 and the second liquid inlet, to meet the laundry treatment demands.
[0099] By providing the control valve 209, it is possible to effectively control the water supply pipeline, thereby realizing the supply of the clean water according to the demands, and further satisfying the use demand of the laundry treatment device 100.
[0100] In some embodiments of the present application, as shown in FIGS. 1 to 3, the delivery assembly 20 further includes a first pipeline 204, a second pipeline 205, a third pipeline 206, a second nozzle 202, a third nozzle 203, and a water pump 210. One end of the first pipeline 204 is connected (fixed by a hoop) to the liquid outlet 20811 of the mixing assembly 208, and another end of the first pipeline 204 is connected (fixed by a hoop) to the inlet port 2011 of the first nozzle 201. One end of the second pipeline 205 is connected (fixed by a hoop) to the control valve 209 of the water supply pipeline, and another end of the second pipeline 205 is connected (fixed by a hoop) to the second nozzle 202. The second nozzle 202 is mounted on the door seal 30 and faces toward the door body of the laundry treatment device 100. One end of the third pipeline 206 is connected (fixed by a hoop) to a water outlet of the water pump 210, and a water inlet of the water pump 210 is connected to the outer drum and the inner drum of the laundry treatment drum 10 (a water accumulation position between the outer drum and the inner drum). The third nozzle 203 is mounted on the door seal 30 and faces toward the laundry treatment chamber 11 of the laundry treatment device 100. Another end of the third pipeline 206 is connected (fixed by a hoop) to the third nozzle 203.
[0101] When the laundry treatment device 100 is in operation, the detergent cartridge assembly 207 and the water supply pipeline respectively inject the detergent and the clean water into the mixing assembly 208 to allow a mixed solution to be formed. The mixed solution is delivered into the laundry treatment chamber 11 via the first pipeline 204 and the first nozzle 201 to realize the supply of the mixed solution. The water supply pipeline delivers the clean water to the door body through the second pipeline 205 and the second nozzle 202, so that the door body is washed during the laundry treatment process. The washing pump conveys the water between the outer drum and the inner drum to the third nozzle 203 through the third pipeline 206, and delivers the water into the laundry treatment chamber 11 through the third nozzle 203, thereby realizing the rinsing of the laundries.
[0102] It should be noted that the second nozzle 202 and the third nozzle 203 may have the same structure as the first nozzle 201 or different structures from the first nozzle 201.
