Therefore, they should not be construed as limiting this invention.

[0036] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] like Figures 1-5 As shown in the embodiment of the present invention, a clothing processing device is introduced, including: a washing chamber 3 for providing space to accommodate clothing; a dispensing component 2 connected to the washing chamber 3 via a water supply pipe, having a flow channel through which a mixed liquid to be dispensed flows; an acceleration chamber 22 provided on the flow channel for the mixed liquid to be dispensed to flow through; the acceleration chamber 22 is provided with an acceleration structure 221 for pressurizing and accelerating the flowing mixed liquid; and an air inlet 24 for introducing external atmospheric gas into the acceleration chamber 22.

[0038] Through the above arrangement, by opening the air inlet 24 on the plenum chamber of the dispensing assembly 2 with premixing function, the external air is drawn into the dispensing assembly 2 through the acceleration structure 221 and discharged into the washing chamber 3, the washing chamber 3 is ventilated, so that the dispensing assembly 2 has different functions in different use scenarios, thereby reducing the number of functional device settings in the clothes treatment device, reducing the cost of the clothes treatment device, and reducing the overall volume of the clothes treatment device.

[0039] In the embodiment of the application, the acceleration chamber 22 is in communication with the water outlet 202 of the dispensing assembly 2.

[0040] In the embodiment of the application, the dispensing assembly 2 is a columnar structure, and the acceleration chamber 22 is located at one end of the columnar dispensing assembly 2. The outer periphery of the acceleration chamber 22 is radially outwardly convex, and the air inlet 24 is arranged on the first end face of the acceleration chamber 22 close to the middle part of the dispensing assembly. This arrangement avoids affecting the communication between the mixing chamber 21 and the acceleration chamber 22 and reduces the water supply flow of the dispensing assembly 2 due to the arrangement of the air inlet 24.

[0041] In the embodiment of the application, the air inlet 24 is arranged around the outer periphery of the first end face.

[0042] In a further embodiment of the application, each air inlet 24 is equidistantly arranged around the outer periphery of the first end face, so that the air inlets 24 are arranged more regularly, and the gas is uniformly gathered from the outer periphery of the plenum chamber to the center.

[0043] In the embodiment of the application, the water outlet 202 of the dispensing assembly 2 is arranged on the second end face of the acceleration chamber 22, and the second end face is arranged opposite to the first end face. This arrangement enables the plenum chamber to more smoothly guide the gas, and the gas is gathered from the outer periphery of the first end face of the plenum chamber to the center and discharged to the water outlet 202 at the center of the second end face on the opposite side and into the washing chamber 3.

[0044] In the embodiment of the application, the water outlet 202 is coaxially arranged with the acceleration chamber 22.

[0045] In the embodiment of the application, the acceleration structure 221 includes an acceleration impeller 222 rotating around its central axis. The acceleration impeller 222 is arranged on the first end face of the acceleration chamber 22, and the acceleration impeller 222 is coaxially arranged with the water outlet 202.

[0046] In the embodiment of the application, the acceleration impeller 222 is an axial flow impeller. The axial flow impeller better gathers the gas from the outer periphery to the center and pushes the gas to the water outlet 202 opposite to it through the blades of the acceleration impeller 222.

[0047] In the embodiment of the present application, the flow channel is further provided with a mixing cavity 21, and the mixed liquid sequentially passes through the mixing cavity 21 and the acceleration cavity 22; the mixing cavity 21 is provided with a mixing structure 211 for uniformly mixing the flowing mixed liquid; the mixed liquid entering the delivery assembly is first fully stirred through the mixing cavity 21, and then discharged at high speed in the acceleration cavity 22, so that the mixing effect of the mixed liquid by the delivery assembly is better, and the additive is more uniformly distributed in the mixed liquid.

[0048] In the embodiment of the present application, the mixing cavity 21 is in communication with the water inlet 201 of the delivery assembly 2.

[0049] In the embodiment of the present application, the mixing cavity 21 is in communication with the acceleration cavity 22 through a communication channel 236, and the water outlet end of the communication channel 236 is arranged on the first end surface of the acceleration cavity 22; the first end surface of the acceleration cavity 22 is sequentially provided with the water outlet end of the communication channel 236 and the air inlet 24 from the center to the outside.

[0050] Through the above arrangement, when the mixed liquid converges and discharges to the center of the booster cavity through the communication channel 236, the stroke is shorter, and the flow of the mixed liquid is facilitated; at the same time, the water pressure of the mixed liquid at the outer peripheral position of the first end surface is the smallest, the air inlet 24 is opened by adjusting the operating power of the acceleration structure 221, so that gas is mixed into the mixed liquid during water supply, so that the amount of dissolved gas in the mixed liquid is increased, and the delivery assembly 2 can simultaneously pre-mix and micro-bubble process the water, further reducing the number of device settings in the clothes treatment device, saving the internal space occupation of the clothes treatment device; at the same time, when the mixed liquid containing micro-bubbles is sprayed to the surface of the clothes, the micro-bubbles make the mixed liquid foam automatically, which increases the contact area of the mixed liquid and the clothes, and can more uniformly and sufficiently clean and wash the clothes, thereby improving the cleaning effect; and when the gas-containing mixed liquid enters the acceleration cavity 22, the acceleration structure 221 in the acceleration cavity 22 not only accelerates the discharge of the mixed liquid, but also fully stirs the mixed liquid and the gas, so that the gas pre-mixed liquid is uniformly mixed to form gas-soluble water, thereby improving the uniform cleaning of the mixed liquid containing micro-bubbles on the clothes and improving the cleaning efficiency.

[0051] In the embodiment of the present application, the pressure head of the acceleration assembly is greater than that of the mixing assembly; so that when the delivery assembly 2 operates, the negative pressure generated by the acceleration cavity 22 through the liquid discharge of the acceleration assembly mainly sucks the liquid in the communication channel 236 and the mixing cavity 21 upstream.

[0052] In the embodiment of the present application, the mixing structure 211 and the acceleration structure 221 share a set of driving structure 231.

[0053] Through the above setting, through the scheme that the mixed solution first passes through the mixing cavity 21 and then is discharged by pressurization, the type of additive that the feeding assembly 2 can be applied to is improved, and the universality of the feeding assembly 2 with the premixing function is improved. By sharing one driving structure 231 for the mixing structure 211 and the acceleration structure 221, the number of driving structures 231 is reduced, the overall volume of the feeding assembly 2 is reduced, the occupation of the internal space of the clothes treatment device is reduced, and the cost is reduced. At the same time, the mixing structure 211 and the acceleration structure 221 can be started and stopped and the rotating speed can be adjusted at the same time through one set of driving structure 231, so that the control of the clothes treatment device is more accurate and convenient.

[0054] In the embodiment of the application, the mixing cavity 21 of the feeding assembly 2 is communicated with the upstream additive feeding assembly 1 through the water inlet 201. Preferably, the mixing structure 211 and the acceleration structure 221 in the feeding assembly 2 share the same driving structure 231.

[0055] Through the above setting, when the gas is introduced into the washing cavity 3 by driving the acceleration structure 221, the mixing structure 211 also operates at the same time. The mixing structure 211 pushes the gas in the mixing cavity 21 into the communication channel 236, so that a negative pressure is formed in the mixing cavity 21. Therefore, the mixing cavity 21 sucks the gas in the water supply pipeline 101 upstream of the water inlet 201 and the cavity inside the additive feeding assembly 1, and discharges the gas into the washing cavity 3 through the acceleration structure 221. Therefore, the feeding assembly 2 can ventilate the entire water supply pipeline and the additive feeding assembly 1, avoid mold growth in the water supply pipeline due to moisture, and reduce the bacterial content of the mixed solution introduced into the washing cavity 3, thereby affecting the washing effect.

[0056] In the embodiment of the application, the driving cavity 23 is further arranged between the mixing cavity 21 and the acceleration cavity 22, and the driving structure 231 for driving the mixing structure 211 and the acceleration structure 221 is arranged in the driving cavity 23. The communication channel 236 is arranged outside the driving cavity 23. Therefore, the internal structure of the feeding assembly 2 is more reasonable and compact, and space waste is avoided.

[0057] In the embodiment of the application, the driving cavity 23 is coaxially arranged with the cylindrical feeding assembly 2.

[0058] In the embodiment of the application, the driving structure 231 includes a driving shaft 232, which is driven to rotate around the axis thereof by the driving structure 231. The driving structure 231 is connected to the mixing structure 211 and the acceleration structure 221 through the two ends of the driving shaft 232.

[0059] Through the above setting, the two ends of the driving shaft 232 are connected with the mixing structure 211 of the mixing cavity 21 and the accelerating structure 221 of the accelerating cavity 22 located on both sides of the driving cavity 23 respectively, so that the mixing structure 211 and the accelerating structure 221 are simultaneously driven by a group of driving structures 231.

[0060] In the embodiment of the present application, the driving cavity 23 is provided with an opening on the adjacent side wall of the mixing cavity 21 and the accelerating cavity 22 respectively, and a bearing 233 is arranged in each opening. The two ends of the driving shaft 232 extend into the mixing cavity 21 or the accelerating cavity 22 through the central holes of the corresponding bearings 233. The two ends of the driving shaft 232 are supported by the two bearings 233, so that the driving shaft 232 is positioned without increasing the friction during rotation.

[0061] In the embodiment of the present application, the driving structure 231 includes a stator 235 for converting electric energy into an electromagnetic field and a rotor 234 for sensing the electromagnetic field and rotating. The rotor 234 is coaxially installed in the middle of the driving shaft 232. The stator 235 is installed in the driving cavity 23 and coaxially sleeved outside the rotor 234 with a certain distance from the rotor 234.

[0062] In the embodiment of the present application, the middle of the feeding assembly 2 is provided with a mounting base 238, which forms a driving cavity 23 for installing the driving structure 231 inside. The mounting base 238 separates the mixing cavity 21 and the accelerating cavity 22 at the two ends of the feeding assembly 2. The outer periphery of the mounting base 238 is circumferentially distributed with communication channels 236 which are isolated from the driving cavity 23. The mixing cavity 21 is connected with the accelerating cavity 22 through the communication channels 236.

[0063] In the embodiment of the present application, each communication channel 236 is arranged around the axis of the driving cavity 23.

[0064] In the embodiment of the present application, the feeding assembly 2 has an outer shell 203. The mounting base 238 is located in the middle segment of the cavity inside the outer shell 203 and separates the left and right segments of the cavity, so that the cavity is divided into the mixing cavity 21, the driving cavity 23 and the accelerating cavity 22.

[0065] In the embodiment of the present application, the mounting base 238 is integrally arranged with the outer shell 203 of the feeding assembly 2.

[0066] In the embodiment of the present application, the accelerating structure 221 includes an accelerating impeller 222 which rotates around its central axis to mix and stir the mixed liquid and gas flowing through, and pressurize and speed up the mixed liquid to be discharged from the feeding assembly 2 through the water outlet 202. The communication channel 236 is connected with the cavity wall where the accelerating impeller 222 is arranged.

[0067] The liquid outlet end of each communication channel 236 is arranged at the outer circumferential position of the accelerating impeller 222.

[0068] In the embodiment of the present application, the accelerating cavity 22 is further provided with a water outlet 202; the accelerating impeller 222 is an axial flow impeller, and the accelerating impeller 222 and the water outlet 202 are arranged at the opposite two side walls of the accelerating cavity 22.

[0069] In the embodiment of the present application, the accelerating impeller 222 is coaxially arranged with the water outlet 202 of the adding assembly 2.

[0070] In the embodiment of the present application, the two end surfaces of the mounting base 238 are respectively provided with a first wall facing the mixing cavity 21 and a second wall facing the accelerating cavity 22; each communication channel 236 extends from the outer circumferential surface of the first wall to the second wall in parallel with each other; the water inlet 201 and the water outlet 202 are respectively arranged at the center of the two end surfaces of the adding assembly 2; and the directions of the water inlet 201 and the water outlet 202 are respectively arranged in parallel with the axis of each communication channel 236.

[0071] Through the above arrangement, when the additive enters the adding assembly 2, it first enters the mixing cavity 21 to be mixed and dissolved, and then enters the accelerating cavity 22 to be accelerated and discharged into the washing cavity 3, forming a water inlet process of mixing and dissolving first and then adding; when the water in the water inlet assembly 1 is flushed into the water supply channel 101, usually no water pressure can push the water into the mixing cavity 21; the accelerating structure 221 forms a negative pressure in the accelerating cavity 22, which has an accelerating effect on the mixing cavity 21 and the water supply channel 101, so that the water in the water supply channel 101 can enter the mixing cavity 21 under pressure; and such water inlet process enables the adding assembly 2 to be applicable to powder type additives such as washing powder and bleaching powder; when the water in the water inlet assembly 1 is flushed into the adding assembly 2, the water and the additive can be fully mixed through the mixing structure 211, and the water and the powder type additive are fully mixed into a mixed liquid without solid substances, which is then discharged into the clothes treatment device through the accelerating structure 221, so as to realize the essence washing function of the clothes by using the dry powder type additive.

[0072] The water enters the mixing cavity 21 from the middle part of the mixing cavity 21, the first wall has a buffering effect on the water, so that the water is dispersed to the periphery, and then discharged through each communication channel 236, forming a relatively tortuous water channel flow direction, so that the water and the additive are more fully mixed and dissolved.

[0073] In the embodiment of the present application, the first one-way valve 237 is arranged in the communication channel 236, so that the communication channel 236 is unidirectionally communicated from the mixing cavity 21 to the accelerating cavity 22.

[0074] Through the above arrangement, through the arrangement of the first one-way valve 237, the backflow of the water through the dispensing device to the components upstream of the dispensing assembly 2 is effectively prevented, and the first one-way valve 237 can effectively block the overflow of the foam generated by the mixed liquid in the washing cavity 3 and the acceleration cavity 22, and avoid the problem of overflow of the foam.

[0075] In the embodiment of the application, the first one-way valve 237 is arranged at the inlet and outlet of each communication channel 236.

[0076] In the embodiment of the application, the first wall and the second wall have the same thickness, and the thickness is greater than the thickness of other parts of the mounting base 238, so as to facilitate the fixation of the bearing 233.

[0077] In the embodiment of the application, the mixing structure 211 comprises a mixing impeller 212 rotating around a central axis thereof, for stirring the mixed liquid in the mixing cavity 21 and dispersing into each communication channel 236 at the outer periphery; the mixing impeller 212 is coaxially arranged with the water inlet 201; the water is subjected to high-speed rotational mixing through the rotation of the blades of the mixing impeller 212, so that the water moves outward from the center of the mixing impeller 212 to the outer periphery in the form of centrifugal motion, greatly improving the mixing effect.

[0078] In the embodiment of the application, the mixing impeller 212 is a centrifugal impeller; so that the mixed liquid moves outward to the outer periphery better.

[0079] In the embodiment of the application, the mixing structure 211 and the acceleration structure 221 each further comprise a speed changer; the two ends of the driving shaft 232 are connected to the mixing impeller 212 and the acceleration impeller 222 through the speed changers, respectively; the mixing structure 211 and the acceleration structure 221 are respectively operated at different speeds through the speed changers, since the mixing structure 211 is used for stirring the mixed liquid in the mixing cavity 21, and the acceleration structure 221 is used for accelerating the mixed liquid in the acceleration cavity 22 to be discharged, the above two structures have different requirements for the speed due to different use scenarios, through the arrangement of the speed changer, one driving shaft 232 can drive the mixing structure 211 and the acceleration structure 221 to respectively mix and stir the mixed liquid and accelerate the mixed liquid to be discharged at different speeds.

[0080] In the embodiment of the application, the mixing impeller 212 and the acceleration impeller 222 are respectively connected to one end of the driving shaft 232, and a clutch is further arranged between the mixing impeller 212 and the acceleration impeller 222 and the corresponding end of the driving shaft 232; when the laundry treatment device is working, the mixing impeller 212 and the acceleration impeller 222 are connected or separated from the corresponding end of the driving shaft 232 through the corresponding clutch.

[0081] In the embodiment of the present application, the mixing impeller 212 and the accelerating impeller 222 are coaxially arranged with the columnar dispensing assembly 2 respectively; the mounting base 238 is arranged with the communication channel 236 surrounding the axis of the dispensing assembly 2; so that the mixed liquid in the mixing cavity 21 is dispersed outward from the central axis and discharged from the mixing cavity 21 through the communication channel 236, and then gathered to the central axis direction from the outer periphery of the accelerating cavity 22 and discharged from the water outlet 202.

[0082] In the embodiment of the present application, the driving shaft 232 is coaxially arranged with the central axis of the columnar dispensing assembly 2.

[0083] In the embodiment of the present application, the additive dispensing assembly 2 is used for dispensing additives into the water supply channel 101; the additive dispensing assembly 2 is in communication with the mixing cavity 21 of the dispensing assembly 2.

[0084] Through the above arrangement, the mixed liquid in the water supply channel 101 between the additive dispensing assembly 1 and the dispensing assembly 2 is sucked by the accelerating structure 221, so that the mixed liquid in the water supply channel 101 flows under pressure, thereby reducing the pipe diameter of the water supply pipeline based on the conventional water supply pipeline, while ensuring the water inflow, and saving certain cost.

[0085] In use, the water flows into the additive dispensing assembly 1 through the water inlet pipe, mixes with part of the additives in the additive dispensing assembly 1 to form mixed liquid, and flushes the remaining part of the undissolved additives into the water supply channel 101 and then is mixed and discharged into the washing cavity 3 by the dispensing assembly 2.

[0092] In the embodiment of the present application, the working steps of the ventilation program include:

[0093] S1: start the ventilation program;

[0094] S2: start the dispensing assembly 2;

[0095] S7: close the dispensing assembly 2 and end the ventilation program.

[0096] In the embodiment of the present application, the second one-way valve 241 is arranged on each air inlet 24, and when the ventilation program is executed, at least includes a first ventilation state in which the dispensing assembly 2 is started to run at a first power, and in this state, the second one-way valve 241 is opened to aerate the washing cavity 3.

[0102] In the embodiment of the application, when the adding assembly 2 is operated in the first ventilation state, the water content rate of the washing cavity 3 in the washing cavity 3 is obtained, and it is judged whether the water content rate of the washing cavity 3 is greater than or equal to the preset second water content rate; if not, the adding assembly 2 is stopped, and the ventilation program is ended.

[0103] In the embodiment of the application, the further working steps of the ventilation program include:

[0104] S1: start the ventilation program, and execute S2;

[0105] S2: start the adding assembly 2, and execute S3;

[0106] S3: operate the adding assembly 2 in the second ventilation state, and execute S4;

[0107] S4: obtain the water content rate of the pipeline, and judge whether the water content rate of the pipeline is greater than or equal to the first water content rate; if yes, execute S3; if not, execute S5;

[0108] S5: operate the adding assembly 2 in the first ventilation state, and execute S6;

[0109] S6: obtain the water content rate of the washing cavity 3, and judge whether the water content rate of the washing cavity 3 is greater than or equal to the second water content rate; if yes, execute S5; if not, execute S7;

[0110] S7: close the adding assembly 2, and end the ventilation program.

[0111] In the embodiment of the application, when operated in the second ventilation state, the water content rate of the pipeline is obtained in real time; when operated in the first ventilation state, the water content rate of the washing cavity 3 is obtained in real time.

[0112] In the embodiment of the application, during the water inlet process, the adding assembly 2 is operated, and the accelerating structure 221 is controlled to operate to open the air inlet 24, so as to guide the gas into the communication channel 236.
