[0082] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0083] like Figures 1 to 6 As shown, according to the first aspect of the embodiment of the present disclosure, a delivery system 100 is proposed, comprising: a liquid storage component 110, having a liquid storage cavity; a multi-way pipe fitting 120, comprising a first liquid inlet pipe section 121, a second liquid inlet pipe section 122 and a liquid outlet pipe section 123, wherein the first liquid inlet pipe section 121 and the second liquid inlet pipe section 122 are both connected to the liquid outlet pipe section 123, the first liquid inlet pipe section 121 is used for water intake, and the liquid outlet pipe section 123 is used for connecting to a clothing processing cavity of a clothing processing device; a pumping component 150, connected to the second liquid inlet pipe section 122, the pumping component 150 is used to pump fluid from the liquid storage component 110 to the second liquid inlet pipe section 122, or to pump fluid from the second liquid inlet pipe section 122 to the liquid storage component 110; and a control unit, used to control the pumping direction of the pumping component 150.

[0084] It can be understood that the delivery system 100 provided in the embodiment of the present disclosure is provided with a liquid storage component 110, a multi-way pipe fitting 120, a pumping component 150 and a control component. Among them, the multi-way pipe fitting 120 is provided with a first liquid inlet pipe section 121, a second liquid inlet pipe section 122 and a liquid outlet pipe section 123. And the first liquid inlet pipe section 121, the second liquid inlet pipe section 122 and the liquid outlet pipe section 123 are connected to each other. The first liquid inlet pipe section 121 is used for water inlet, and the second liquid inlet pipe section 122 is connected to the liquid storage component 110, so that the detergent in the liquid storage cavity can flow into the second liquid inlet pipe section 122. The liquid outlet pipe section 123 can be connected to the clothing processing cavity of the clothing processing device. With such a configuration, the clothes to be washed are put into the clothes processing chamber, the washing water flows into the first liquid inlet pipe section 121, the detergent flows into the second liquid inlet pipe section 122, and the washing water and the detergent are combined and fully mixed in the liquid outlet pipe section 123, and the mixed liquid of the washing water and the detergent is transported to the clothes processing chamber through the liquid outlet pipe section 123 for subsequent washing operations on the clothes to be washed. The washing water and the detergent can be fully mixed without the need to set up an additional mixing box, and the structure is simple and reliable, so that the delivery system 100 occupies less space in the clothes processing equipment, and can more reasonably plan the internal space of the clothes processing equipment, which is convenient for reducing the overall size of the clothes processing equipment, and is more suitable for miniaturized clothes processing equipment, reducing the space occupied by users, and improving user experience. The pumping component 150 is connected to the second liquid inlet pipe section 122, and the control unit can control the pumping direction of the pumping component 150. With such a configuration, during the stage of adding the cleaning agent, the control unit can control the pumping assembly 150 to pump the cleaning agent in the liquid storage assembly 110 to the second liquid inlet pipe section 122, and the pumping assembly 150 provides power to ensure that the delivery of the cleaning agent is smoother and more stable. In the case where there is residual cleaning agent in the second liquid inlet pipe section 122, the control unit can control the pumping assembly 150 to pump the fluid from the second liquid inlet pipe section 122 to the liquid storage assembly 110, so as to flush the cleaning agent remaining on the inner wall of the second liquid inlet pipe section 122 with the fluid, reduce the residual cleaning agent on the inner wall of the second liquid inlet pipe section 122, avoid clogging of the second liquid inlet pipe section 122, and when replacing the cleaning agent, avoid the new cleaning agent and the cleaning agent remaining in the second liquid inlet pipe section 122 from having a mixed taste, thereby improving the user experience.

[0085] Exemplarily, there is an angle between the first liquid inlet pipe section 121 and the second liquid inlet pipe section 122, and the angle is less than or equal to 90°. With such a configuration, on the one hand, a slope can be formed between the second liquid inlet pipe section 122 and the first liquid inlet pipe section 121, and when the cleaning agent is transported along the second liquid inlet pipe section 122 to the liquid outlet pipe section 123, it can slide along the slope into the liquid outlet pipe section 123, thereby ensuring smoother transportation of the cleaning agent; on the other hand, it ensures that the cleaning agent can be continuously transported and will not stay in the second liquid inlet pipe section 122. In the case where the cleaning agent is thick, it is avoided that the cleaning agent hangs on the inner wall of the second liquid inlet pipe section 122, causing cleaning agent residue, failing to meet the ideal cleaning amount, and subsequent difficult processing; on the other hand, there is no need to set up an additional power source in the second liquid inlet pipe section 122 to promote the flow of the cleaning agent, simplify the structure, and reduce costs.

[0086] For example, the number of liquid storage chambers can be set to two, and correspondingly, the number of second liquid inlet pipe sections 122 is also set to two, and each liquid storage chamber corresponds to one second liquid inlet pipe section 122. With such a configuration, different detergents can be contained in different liquid storage chambers to cope with clothes that require multiple detergents to be washed. Different detergents are placed and stored separately, and mixed with the cleaning water transported by the first liquid inlet pipe section 121 at the liquid outlet pipe section 123 to be placed in the clothing processing chamber, so that the user can accurately judge the amount of various detergents to be placed to ensure the washing effect of the clothes.

[0087] For example, when washing a sweater, laundry detergent and softener are needed. The laundry detergent can clean the sweater, and the softener makes the sweater soft and prevents static electricity. The laundry detergent and softener can be put into a liquid storage cavity respectively, and the laundry detergent flows into the corresponding second liquid inlet pipe section 122 from one liquid storage cavity, and enters the liquid outlet pipe section 123 along the second liquid inlet pipe section 122. The softener flows into the corresponding second liquid inlet pipe section 122 from another liquid storage cavity, and enters the liquid outlet pipe section 123 along the second liquid inlet pipe section 122. In the liquid outlet pipe section 123, the laundry detergent, softener and washing water are fully mixed and flow into the clothing processing cavity to act on the sweater.

[0088] For example, when only one liquid storage chamber and one second liquid inlet pipe section 122 are provided, a three-way pipe fitting 120 can be used. When two liquid storage chambers and two second liquid inlet pipe sections 122 are provided, a four-way pipe fitting 120 can be used. Figure 3 As shown, in order to conveniently display the schematic diagram of the four-way pipe fitting, the schematic diagrams of the supply pipeline 130 and the delivery pipeline 140 are hidden.

[0089] For example, Figures 4 to 6As shown, the liquid storage component 110 is provided with a box body 111 and a box cover 112. Among them, the box body 111 may be formed with a delivery port 1101 and a liquid storage cavity, and the user can deliver detergent into the liquid storage cavity through the delivery port 1101. The delivery interface is connected to the liquid storage cavity and the delivery interface is connected to the delivery pipe section. After starting the clothing processing device and delivering the detergent into the liquid storage cavity from the delivery port 1101, the detergent in the liquid storage cavity is pumped from the delivery interface along the delivery pipe section to the second liquid inlet pipe section 122 through the pump body 152. The box cover 112 is covered on the box body 111, and the delivery port 1101 can be opened by operating the box cover 112 to deliver the detergent into the liquid storage cavity from the delivery port 1101. When the delivery system 100 is not in use, the delivery port 1101 can be covered by operating the box cover 112 to prevent foreign matter from entering the liquid storage cavity and ensure the cleanliness of the clothes processed by the subsequent clothing processing device.

[0090] For example, the box cover 112 may be hinged to the box body 111, so that when the box cover 112 is operated to open the delivery port 1101, the box cover 112 will not be separated from the box body 111, which is convenient for operation. A protrusion may be provided at one end of the box cover 112 away from the hinge, so that the user can operate the box cover 112 through the protrusion. Or a rebound switch may be provided at one end of the box body 111 away from the hinge, and the user can press the end of the box cover 112 away from the hinge to pop up the box cover 112 to open the delivery port 1101. Or the popped-up box cover 112 may be pressed toward the box body 111 to cover the delivery port 1101.

[0091] Exemplarily, the access end of the delivery pipe section may be provided with a joint, and the joint is provided with a through hole. The end of the box body 111 provided with the delivery interface is provided with a threaded hole, and the positions of the threaded hole and the through hole correspond. In this way, when the access end of the delivery pipe section is connected to the delivery interface, a bolt can be passed through the through hole and screwed into the threaded hole, so that the delivery pipe section and the delivery interface are connected and tightened to avoid falling off and improve stability.

[0092] Exemplarily, the dispensing system 100 is also provided with a liquid amount detection device, a controller and a prompt unit, and the amount of detergent in the liquid storage chamber can be monitored by the liquid amount detection device. When the liquid amount detection device detects that the amount of detergent in the liquid storage chamber is less than or equal to the preset amount, the liquid amount detection device sends information to the controller, and the controller controls the prompt unit to issue a prompt, so that the user can add detergent to the liquid storage chamber to ensure the subsequent laundry treatment effect. Exemplarily, the prompt unit can be a display panel and / or a buzzer to issue an audible and visual prompt to the user.

[0093] It is understandable that different liquid level detection devices can be selected according to actual usage. Specifically, the liquid level detection device can be a magnetic levitation sensor, which has a simple structure, is easy to install, easy to maintain, and corrosion-resistant, and is suitable for detecting the detergent level in the liquid storage chamber. Or the liquid level detection device can use a negative pressure sensor. The negative pressure sensor has a small structural size, light weight, and high pressure resolution. The liquid level detection data is more accurate and has better stability, which is conducive to long-term and stable detection operations.

[0094] For example, Fig.11 As shown, the magnetic levitation sensor is provided with a magnetic float 1141, a limit column 113 and a magnetic switch. Among them, the limit column 113 is arranged in the liquid storage cavity and arranged along the depth direction of the liquid storage cavity. The magnetic float 1141 is sleeved on the limit column 113 and can slide along the limit column 113. The magnetic switch is arranged on the outer bottom wall of the box body 111 and corresponds to the arrangement of the magnetic float 1141. The less the amount of detergent in the liquid storage cavity, the closer the distance between the magnetic float 1141 and the magnetic switch. In the stage of adding detergent, when the amount of detergent in the liquid storage cavity is less than or equal to the preset amount, the magnetic float 1141 and the magnetic switch will be turned on to send information that the amount of detergent in the liquid storage cavity is insufficient to the controller. After receiving the information, the controller controls the prompt unit to send a prompt that the amount of detergent in the liquid storage cavity is insufficient.

[0095] In some examples, such as Figure 1 and Figure 2 As shown, the above-mentioned delivery system 100 also includes: a supply pipeline 130, including a liquid inlet pipe section and a liquid injection pipe section, one end of the above-mentioned liquid inlet pipe section is connected to the above-mentioned first liquid inlet pipe section 121, and the other end is used for water intake, one end of the above-mentioned liquid injection pipe section is connected to the above-mentioned liquid outlet pipe section 123, and the other end is used to connect to the above-mentioned clothing processing chamber; a delivery pipeline 140, one end of the above-mentioned delivery pipeline 140 is connected to the above-mentioned liquid storage chamber, and the other end is connected to the above-mentioned second liquid inlet pipe section 122.

[0096] It is understandable that the delivery system 100 is also provided with a supply pipeline 130 and a delivery pipeline 140. Among them, the supply pipeline 130 is used to supply cleaning water to the clothing processing chamber. Specifically, the supply pipeline 130 is provided with a liquid inlet pipe section and a liquid injection pipe section. One end of the liquid inlet pipe section is connected to the first liquid inlet pipe section 121, and the other end can be connected to a water source. Thereby, the cleaning water of the water source is transported to the first liquid inlet pipe section 121 through the liquid inlet pipe section. Exemplarily, the water source can be a faucet. One end of the liquid injection pipe section is connected to the liquid outlet pipe section 123, and the other end can be connected to the clothing processing chamber. Thereby, the liquid of the liquid outlet pipe section 123 is transported to the clothing processing chamber. The delivery pipeline 140 is used to deliver the cleaning agent into the second liquid inlet pipe section 122. Specifically, one end of the delivery pipeline 140 is connected to the liquid storage chamber, and the other end is connected to the second liquid inlet pipe section 122. The user can put the detergent into the liquid storage cavity, and the detergent flows into the delivery pipeline 140 through the liquid storage cavity, and then flows into the second liquid inlet pipe section 122 through the delivery pipeline 140. By setting the supply pipeline 130 and the delivery pipeline 140, on the one hand, the delivery system 100 is more flexible and convenient to deliver the cleaning water and detergent to the clothing processing equipment; on the other hand, the installation position of the delivery system 100 in the clothing processing equipment is more diversified; on the other hand, the cleaning water and the detergent are mixed in the liquid outlet pipe section 123 and transported to the clothing processing cavity through the liquid injection pipe section. In the liquid injection pipe section, the cleaning water and the detergent are further mixed to ensure that the mixing is more sufficient and the cleaning effect is improved.

[0097] For example, the liquid inlet pipe section can be arranged adjacent to the multi-way pipe member 120, so that a shorter liquid injection pipe section can be used to inject a mixture of detergent and washing water into the laundry processing chamber to accurately control the injection amount and avoid excessive detergent remaining in the liquid injection pipe section.

[0098] For example, Figures 4 to 8As shown, the delivery system 100 may also be provided with a liquid mixing unit 160. The liquid mixing unit 160 is provided with a tube body 161 and a spoiler 162. Among them, at least two different fluid media can enter the tube body 161 from the first end of the tube body 161, and enter the clothing processing chamber of the clothing processing device from the second end of the tube body 161. The spoiler 162 is provided in the tube body 161, and the fluid channel in the tube body 161 can be separated by the spoiler 162, and the flow channel extends in a zigzag manner from the first end to the second end. Such arrangement enables at least two different fluid media to advance toward the second end along the fluid channel in the tube body 161, and the fluid channel extends in a zigzag manner, thereby increasing the flow length of the fluid medium and improving the mixing degree of the at least two different fluid media. Furthermore, when the at least two different fluid media flow to the bend of the fluid channel, they will collide with the bend, and the bend will disturb the fluid medium, change the flow direction of the fluid and reduce the flow speed, further improving the mixing degree of the at least two different fluid media, thereby making the mixed fluid medium delivered to the clothing treatment chamber have high mixing uniformity and accurate mixing ratio, thereby ensuring the cleanliness of clothing treatment.

[0099] Exemplarily, the spoiler 162 may be a fan blade, a spiral blade or a protruding structure to separate a tortuously extending fluid channel in the tube body 161 to ensure a cutting spoiler effect on the fluid medium.

[0100] It is understandable that a power source may be provided at the first end of the tube body 161 to push at least two different fluid media into the fluid channel and enable them to pass smoothly through the tortuous fluid channel. The pressure of the fluid medium is increased, the collision strength with the tortuous part of the fluid channel is increased, and the degree of mixing is further improved. For example, the power source may be a peristaltic pump.

[0101] Exemplarily, the tube body 161 may be made of a transparent material to facilitate observation of the spoiler 162 disposed inside the tube body 161 and whether there is residual fluid on the inner wall of the tube body 161 , thereby facilitating subsequent maintenance operations.

[0102] For example, the fluid medium may include a variety of detergents and cleaning water. The detergents and cleaning water may be introduced from the first end of the tube body 161, and then mixed sufficiently through the tortuously extending fluid channel and transported to the clothing processing chamber to ensure a cleaning effect on the clothing.

[0103] For example, Figure 8As shown, the above-mentioned spoiler 162 includes: a first spoiler blade 1621, which is arranged in the above-mentioned tube body 161 and forms a first guide surface. The above-mentioned first guide surface is arranged obliquely relative to the axial direction of the above-mentioned tube body 161, or the above-mentioned first guide surface is a spiral surface extending along the axial direction of the above-mentioned tube body 161; wherein, a first channel section is formed between the above-mentioned first guide surface and the inner wall of the above-mentioned tube body 161, and the above-mentioned fluid channel includes the above-mentioned first channel section.

[0104] It is understandable that the spoiler 162 may be provided with a first spoiler blade 1621. Specifically, the first spoiler blade 1621 is provided in the tube body 161, and the first spoiler blade 1621 forms a first guide surface in the tube body 161, and at least two different fluid media flow from the first end to the second end along the first guide surface. Wherein, when the first guide surface is arranged obliquely relative to the axial direction of the tube body 161, the fluid medium collides with the obliquely arranged first spoiler blade 1621 during the flow process, slowing down the flow speed of the fluid medium, and the power source is the power applied to the fluid medium into the pressure on the first spoiler blade 1621, under the action of the pressure, at least two different fluid media are forced to mix, improving the mixing uniformity, and the collision with the first spoiler blade 1621 can change the flow direction of the fluid medium, flowing along the oblique direction of the first guide surface, thereby extending the flow distance of the fluid medium, further improving the mixing uniformity.

[0105] In the case where the first guide surface is a helical surface extending along the axial direction of the tube body 161, the fluid medium will collide with the helical surface during the flow process, thereby slowing down the flow speed of the fluid medium, and the power source converts the power applied by the fluid medium into pressure on the helical surface. Under the action of pressure, at least two different fluid media are forced to mix, thereby improving the mixing uniformity, and the fluid medium can flow along the spiral direction of the helical surface, the helical surface cuts the fluid medium, and extends the flow distance of the fluid medium, thereby further improving the mixing uniformity.

[0106] It can be understood that, when the first guide surface is arranged obliquely relative to the axial direction of the above-mentioned tube body 161, a plurality of first spoiler blades 1621 can be provided to improve the mixing effect of at least two different fluid media, and the specific number of settings can be selected according to actual conditions. If too few first spoiler blades 1621 are provided, the mixing effect of at least two different fluid media will be poor. If too many first spoiler blades 1621 are provided, the flow resistance of at least two different fluid media will be large, and sufficient power is required to drive the fluid medium to flow, thereby increasing energy consumption.

[0107] For example, Figure 8As shown, the spoiler 162 may be provided with a second spoiler blade 1622. Specifically, the second spoiler blade 1622 is arranged in the tube body 161, and the second spoiler blade 1622 forms a second guide surface in the tube body 161, and at least two different fluid media flow from the second end to the second end along the second guide surface. Wherein, when the second guide surface is arranged obliquely relative to the axial direction of the tube body 161, the fluid medium collides with the obliquely arranged second spoiler blade 1622 during the flow process, slowing down the flow speed of the fluid medium, and the power source is the power applied to the fluid medium into the pressure on the second spoiler blade 1622, under the action of the pressure, at least two different fluid media are forced to mix, improving the mixing uniformity, and the collision with the second spoiler blade 1622 can change the flow direction of the fluid medium, flowing along the oblique direction of the second guide surface, thereby extending the flow distance of the fluid medium, further improving the mixing uniformity.

[0108] In the case where the second guide surface is a helical surface extending along the axial direction of the tube body 161, the fluid medium will collide with the helical surface during the flow process, thereby slowing down the flow speed of the fluid medium, and the power source converts the power applied by the fluid medium into pressure on the helical surface. Under the action of pressure, at least two different fluid media are forced to mix, thereby improving the mixing uniformity, and the fluid medium can flow along the spiral direction of the helical surface, the helical surface cuts the fluid medium, and extends the flow distance of the fluid medium, thereby further improving the mixing uniformity.

[0109] It is understandable that the second spoiler blade 1622 can be arranged on one side of the first spoiler blade 1621, and the fluid medium will pass through the first channel section and the second channel section in sequence, and under the joint action of the first guide surface and the second guide surface, the mixing degree of at least two different fluid media is guaranteed. The first spoiler blade 1621 and the second spoiler blade 1622 are different in at least one of size, shape and setting angle.

[0110] It can be understood that, when the second guide surface is arranged obliquely relative to the axial direction of the above-mentioned tube body 161, a plurality of second spoiler blades 1622 can be provided to improve the mixing effect of at least two different fluid media, and the specific number of settings can be selected according to actual conditions. If too few second spoiler blades 1622 are provided, the mixing effect of at least two different fluid media will be poor. If too many second spoiler blades 1622 are provided, the flow resistance of at least two different fluid media will be large, and sufficient power is required to drive the fluid medium to flow, thereby increasing energy consumption.

[0111] Exemplarily, when the first guide surface and the second guide surface are both arranged obliquely relative to the axial direction of the tube body 161, the inclination angle of the first guide surface relative to the axial direction is the same as the inclination angle of the second guide surface relative to the axial direction and is opposite in direction.

[0112] It can be understood that the first guide surface and the second guide surface can be arranged obliquely relative to the axial direction of the tube body 161. The first spoiler blade 1621 and the second spoiler blade 1622 have the same size, the same inclination angle value and opposite direction relative to the axial direction of the tube body 161, so that the inclination angle of the first guide surface relative to the axial direction of the tube body 161 and the inclination angle of the second guide surface relative to the axial direction of the tube body 161 are the same and opposite in direction. In this way, when the fluid medium passes through the first guide surface and the second guide surface, opposite flow directions will be generated, and the fluid medium in opposite flow directions will collide, thereby increasing the mixing degree of at least two different fluid media. And the flow of the fluid medium in opposite directions further extends the flow distance of the fluid medium, further increasing the mixing degree of at least two different fluid media. Under the action of the power source providing power, the fluid medium as a whole flows from the first end to the second end, ensuring that the mixed fluid medium is stably transported to the clothing processing chamber.

[0113] Exemplarily, the first guide surface is arranged closer to the first end than the second guide surface, and the first guide surface is inclined at 45° to the axial direction of the tube body 161, and the inclination direction is toward the second end. The second guide surface is arranged closer to the second end than the first guide surface, and the second guide surface is inclined at 135° to the axial direction of the tube body 161, and the inclination direction is toward the first end. The number of the first spoiler blades 1621 and the second spoiler blades 1622 are both 4, and the distances between adjacent first spoiler blades 1621 are equal, and the distances between adjacent second spoiler blades 1622 are equal.

[0114] For example, Figure 8 As shown, in the case where both the first guide surface and the second guide surface are helical surfaces extending along the axial direction of the tube body 161, the rotation direction of the first guide surface is opposite to that of the second guide surface.

[0115] It is understandable that the first guide surface and the second guide surface can be set as a spiral surface extending along the axial direction of the tube body 161, and the first spoiler blade 1621 and the second spoiler blade 1622 have the same size and opposite directions, so that the rotation direction of the first guide surface is opposite to the rotation direction of the second guide surface. In this way, when the fluid medium passes through the first guide surface and the second guide surface, opposite spiral motion directions will be generated, and the fluid medium in opposite spiral motion directions will collide. Under the support of the spiral force, the disturbance ability of the first guide surface and the second guide surface on the fluid medium and the cutting ability of the fluid medium are improved, thereby improving the mixing degree of at least two different fluid media. And the flow of the fluid medium in the opposite spiral surface direction further extends the flow distance of the fluid medium, and further improves the mixing degree of at least two different fluid media. Under the action of the power source providing power, the fluid medium as a whole flows from the first end to the second end, ensuring that the mixed fluid medium is stably transported to the clothing processing chamber.

[0116] Exemplarily, the first guide surface is arranged closer to the first end than the second guide surface, and the helix angle of the first guide surface is 45°, and the inclination direction is toward the second end. The second guide surface is arranged closer to the second end than the first guide surface, and the helix angle of the second guide surface is 135° and the inclination direction is toward the first end. The distances between adjacent first spoiler blades 1621 are equal, and the distances between adjacent second spoiler blades 1622 are equal.

[0117] Exemplarily, the number of the first spoiler blade 1621 and the second spoiler blade 1622 is multiple, so as to increase the guide area of ​​the first guide surface and the guide area of ​​the second guide surface. And the first spoiler blade 1621 and the second spoiler blade 1622 are arranged alternately. Each first spoiler blade 1621 and an adjacent second spoiler blade 1622 can form a spoiler joint. When the fluid medium passes through the spoiler joint, a flow effect in the opposite direction can be generated, and a collision can be generated between the fluid medium in different flow directions, and the fluid medium and the first guide surface and the second guide surface all collide, thereby increasing the mixing degree of at least two different fluid media. And such an arrangement extends the flow distance of the fluid medium, further increasing the mixing degree of at least two different fluid media. Under the action of power provided by the power source, the fluid medium as a whole flows from the first end to the second end, ensuring that the mixed fluid medium is stably delivered to the clothing processing chamber.

[0118] Exemplarily, when both the first guide surface and the second guide surface are spiral surfaces, along the circumference of the tube body 161, an angle is formed between an end of the first guide surface close to the second guide surface and an end of the second guide surface close to the first guide surface.

[0119] It is understandable that both the first guide surface and the second guide surface can be selected as spiral surfaces, and the first guide surface and the second guide surface can be arranged alternately, and the spiral angles of the first guide surface and the second guide surface are opposite. Each first spoiler blade 1621 and an adjacent second spoiler blade 1622 can form a spoiler joint, and when the fluid medium passes through the spoiler joint, a flow effect in the opposite direction will be produced, and collisions can be generated between fluid media in different flow directions, and collisions are generated between the fluid medium and the first guide surface and the second guide surface, thereby improving the mixing degree of at least two different fluid media. And so arranged, the flow distance of the fluid medium is extended, and the mixing degree of at least two different fluid media is further improved. An angle is formed between one end of the first guide surface close to the second guide surface and one end of the second guide surface close to the first guide surface, thereby further improving the disturbance and cutting ability of the fluid medium, and ensuring that at least two different fluid media are mixed evenly.

[0120] Exemplarily, the angle formed between one end of the first guide surface close to the second guide surface and one end of the second guide surface close to the first guide surface is 90°, so as to achieve the maximum cutting effect and turbulence effect of the angle on the fluid medium.

[0121] Exemplarily, the spoiler 162 is rotatably disposed in the tube body 161 .

[0122] It is understandable that the spoiler 162 can be actively rotatably arranged in the tube body 161. A driving member can be provided to drive the spoiler 162 to rotate, so as to improve the stirring effect on the fluid medium, thereby improving the mixing degree of at least two different fluid media. And the speed of rotation and the direction of rotation are controllable, so as to achieve the ideal rotation effect. For example, the driving member can be a driving motor, and the output shaft of the driving motor is connected to the rotating shaft of the spoiler 162. Or the spoiler 162 can be passively rotatably arranged in the tube body 161. When the fluid medium collides with the spoiler 162, the spoiler 162 is rotated around the axis direction of the tube body 161 to improve the stirring effect on the fluid medium. The structure is simple and the cost is reduced.

[0123] Exemplarily, the first spoiler blade 1621 and the second spoiler blade 1622 are coaxially connected so that the first spoiler blade 1621 and the second spoiler blade 1622 can rotate synchronously; wherein, when the first guide surface and the second guide surface are both arranged obliquely relative to the axial direction of the tube body 161, the inclination angle of the first guide surface relative to the axial direction is the same as the inclination angle of the second guide surface relative to the axial direction and is opposite in direction; when the first guide surface and the second guide surface are both helical surfaces extending along the axial direction of the tube body 161, the rotation direction of the first guide surface is opposite to that of the second guide surface.

[0124] It is understandable that the first spoiler blade 1621 and the second spoiler blade 1622 can use the same rotating shaft so that the first spoiler blade 1621 and the second spoiler blade 1622 rotate synchronously, which is convenient for setting and has a simple structure. And when the first guide surface and the second guide surface are both arranged obliquely relative to the axial direction of the tube body 161, the inclination angle of the first guide surface relative to the axial direction is the same as the inclination angle of the second guide surface relative to the axial direction and is opposite in direction. When the spoiler 162 rotates, the fluid medium can be stirred in opposite directions, thereby improving the collision effect of the fluid medium flowing in opposite directions to enhance the mixing effect of at least two different fluid media. Under the action of the power source providing power, the fluid medium as a whole flows from the first end to the second end, ensuring that the mixed fluid medium is stably transported to the clothing processing chamber.

[0125] Exemplarily, the first guide surface is inclined at 45° to the axial direction of the tube body 161, and the inclined direction is toward the second end. The second guide surface is inclined at 135° to the axial direction of the tube body 161, and the inclined direction is toward the first end.

[0126] It is understandable that, when both the first guide surface and the second guide surface are spiral surfaces extending along the axial direction of the tube body 161, the rotation direction of the first guide surface is opposite to that of the second guide surface. When the spoiler 162 rotates, the fluid medium can be stirred in opposite directions, thereby improving the collision effect of the fluid medium flowing in opposite directions, so as to enhance the mixing effect of at least two different fluid media. Under the action of the power source providing power, the fluid medium as a whole flows from the first end to the second end, ensuring that the mixed fluid medium is stably delivered to the clothing processing chamber.

[0127] Exemplarily, the first spoiler blade 1621 and the second spoiler blade 1622 can rotate independently, and the first spoiler blade 1621 and the second spoiler blade 1622 turn in opposite directions; wherein, when the first guide surface and the second guide surface are both arranged obliquely relative to the axial direction of the tube body 161, the inclination angle of the first guide surface relative to the axial direction is consistent with the inclination angle of the second guide surface relative to the axial direction; when the first guide surface and the second guide surface are both spiral surfaces extending along the axial direction of the tube body 161, the rotation direction of the first guide surface is consistent with the rotation direction of the second guide surface.

[0128] It is understandable that the first spoiler blade 1621 and the second spoiler blade 1622 can rotate independently, so that the rotation of the first spoiler blade 1621 and the second spoiler blade 1622 does not affect each other, thereby improving reliability. And when the first guide surface and the second guide surface are both arranged obliquely relative to the axial direction of the tube body 161, the inclination angle of the first guide surface relative to the axial direction is consistent with the inclination angle of the second guide surface relative to the axial direction, and the rotation direction is opposite. When the first spoiler blade 1621 and the second spoiler blade 1622 rotate in opposite directions, the fluid medium can be stirred in opposite directions, thereby improving the collision effect of the fluid medium flowing in opposite directions, so as to enhance the mixing effect of at least two different fluid media. Under the action of the power source providing power, the fluid medium as a whole flows from the first end to the second end, ensuring that the mixed fluid medium is stably transported to the clothing processing chamber.

[0129] Exemplarily, the first spoiler blade 1621 is tilted at 45° to the axial direction of the tube body 161, and the tilted direction is toward the second end. The second spoiler blade 1622 is tilted at 45° to the axial direction of the tube body 161, and the tilted direction is toward the second end. The first spoiler blade 1621 and the second spoiler blade 1622 rotate in opposite directions.

[0130] It can be understood that, when both the first guide surface and the second guide surface are spiral surfaces extending along the axial direction of the tube body 161, the rotation direction of the first guide surface is the same as that of the second guide surface, and the rotation direction of the first guide surface is opposite to the rotation direction of the second guide surface. When the spoiler 162 rotates, the fluid medium can be stirred in opposite directions, thereby improving the collision effect of the fluid medium flowing in opposite directions, so as to enhance the mixing effect of at least two different fluid media. Under the action of the power source providing power, the fluid medium as a whole flows from the first end to the second end, ensuring that the mixed fluid medium is stably delivered to the clothing processing chamber.

[0131] For example, the first spoiler blade 1621 and the second spoiler blade 1622 can be set to different shapes. When the fluid medium impacts the first spoiler blade 1621 and the second spoiler blade 1622, the force-bearing parts and force-bearing angles of the first spoiler blade 1621 and the second spoiler blade 1622 are different, and the force change formed in the axial direction of the tube body 161 is easy to generate a circumferential force that causes the spoiler 162 to rotate, so that it is more suitable for the case where the driving member is not used to drive the spoiler 162 to rotate. The spoiler 162 can be passively rotated under the action of the fluid medium.

[0132] Exemplarily, the spoiler 162 includes: a plurality of protrusion structures arranged at intervals on the inner wall of the tube body 161 .

[0133] It is understandable that the spoiler 162 may be provided with a plurality of protrusion structures. Specifically, a plurality of protrusion structures may be provided at intervals on the inner wall of the tube body 161. When the fluid medium passes through the plurality of protrusion structures, it will collide with the protrusion structures, change the flow direction of the fluid medium, play a role in spoiling and cutting the fluid medium, and improve the mixing degree of at least two different fluid media. The provision of a plurality of protrusion structures can increase the flow length of the fluid medium, further improving the mixing degree of at least two different fluid media, so that the mixed fluid medium delivered to the clothing treatment chamber has high mixing uniformity and accurate mixing ratio, thereby ensuring the cleanliness of clothing treatment.

[0134] It is understandable that the intervals between the plurality of protrusion structures can be adjusted according to actual conditions, and the intervals between adjacent protrusion structures can be equal or different. The protrusion structures can be arranged on the same side of the axis of the tube body 161 or on both sides of the axis.

[0135] For example, Figure 6 As shown, the liquid mixing unit 160 further includes a limiting portion 163 for limiting the position of the spoiler 162 relative to the tube body 161 .

[0136] It is understandable that the liquid mixing unit 160 may also be provided with a limiting portion 163, through which the position and angle of the spoiler 162 relative to the tube body 161 may be limited, thereby improving the stability of the spoiler 162. Schematically, the limiting portion 163 may be an "L"-shaped rod, wherein one end of the "L"-shaped rod is connected to the liquid outlet pipe section 123 of the delivery system 100, and the other end is connected to the spoiler 162.

[0137] The injection pipe section may be provided with a liquid mixing unit 160. When the cleaning agent enters the injection pipe section through the second liquid inlet pipe section 122 and the liquid outlet pipe section 123, and the cleaning water enters the injection pipe section through the first liquid inlet pipe section 121 and the liquid outlet pipe section 123, the cleaning agent and the cleaning water are further mixed under the action of the liquid mixing unit 160 to ensure uniform mixing. Specifically, the liquid mixing unit 160 may be provided with a flow spoiler 162, and the flow spoiler 162 may separate a fluid channel at the injection pipe section where the liquid mixing unit 160 is located, and the fluid channel extends in a tortuous direction along the liquid flow direction of the injection pipe section. In this way, when the cleaning agent and the cleaning water pass through the flow spoiler 162, they flow along the tortuous fluid channel, and the cleaning agent and the cleaning water are forced to mix under the disturbance of the flow spoiler 162, so that the mixing is more uniform, the accurate ratio of the mixed washing liquid is ensured, and the cleaning agent is prevented from remaining in the second liquid inlet pipe section 122 and the injection pipe section, resulting in insufficient concentration of the mixed washing liquid.

[0138] In some examples, such as Figure 1 and Figure 2As shown, the pumping assembly 150 includes: a pump housing 151, arranged close to the liquid storage assembly 110; a pump body 152, arranged in the pump housing 151, forming the input end and the output end; wherein the pump housing 151 has a fixed structure 1511, and the multi-way pipe fitting 120 and / or the supply pipeline 130 are arranged on the fixed structure 1511.

[0139] It can be understood that the pumping assembly 150 is provided with a pump housing 151 and a pump body 152. Among them, the pump body 152 is arranged in the pump housing 151, and the pump body 152 is provided with an input end and an output end. Among them, the input end of the pump body 152 is connected to the liquid storage assembly 110, and the output end of the pump body 152 is connected to the second liquid inlet pipe section 122. And the pump housing 151 is arranged close to the liquid storage assembly 110, so that the cleaning agent in the liquid storage cavity of the liquid storage assembly 110 enters the pump body 152 through the input end of the pump body 152, which can reduce the residual amount of the cleaning agent at the input end of the pump body 152, ensure that there is sufficient cleaning agent and cleaning water mixed, and ensure the concentration of the mixed washing liquid. The main part of the pump body 152 is protected by the pump housing 151 to ensure that the pump body 152 can operate continuously and stably, and extend the service life of the pump body 152. And the pump housing 151 is provided with a fixed structure 1511. The fixing structure 1511 can fix the multi-way pipe fitting 120 and the supply pipeline 130 to the pump housing 151, ensuring that the relative positions between the pump body 152 and the multi-way pipe fitting 120 and / or the pump body 152 and the supply pipeline 130 are fixed. This ensures that the cleaning agent and cleaning water in the multi-way pipe fitting 120 are stably transported, and the cleaning agent in the supply pipeline 130 is stably transported, thereby improving the reliability and stability of the delivery.

[0140] It should be noted that the number of pump bodies 152 can be set according to the number of liquid storage chambers. Specifically, when there are at least two liquid storage chambers, each liquid storage chamber corresponds to a second liquid inlet pipe section 122 and a pump body 152, so that the pump body 152 can pump the detergent in the corresponding liquid storage chamber into the corresponding second liquid inlet pipe section 122 in a targeted manner. With such a setting, the pumping time of different pump bodies 152 can be adjusted to pump the detergent in different liquid storage chambers into the second liquid inlet pipe section 122 at a preset time interval, or the pumping power of different pump bodies 152 can be adjusted to adjust the flow rate of the detergent in different liquid storage chambers to the second liquid inlet pipe section 122, so as to meet the various washing strategies of the clothing processing equipment and improve the applicability. And multiple pump bodies 152 can be independently connected to the control unit to ensure that the pumping direction of each pump body 152 is controlled in a targeted manner to improve the control accuracy.

[0141] Exemplarily, the fixing structure 1511 may be provided with a slot, and the shape of the receiving portion of the slot matches the multi-way pipe fitting 120 or the supply pipeline 130, and the receiving portion is interference fit with the multi-way pipe fitting 120 or the supply pipeline 130. The opening of the slot is elastic and the size of the opening is smaller than the size of the receiving portion. In this way, the multi-way pipe fitting 120 or the supply pipeline 130 can be pressed from the opening of the slot into the receiving portion of the slot, and the opening of the slot is restored to its original state, so as to ensure that the slot stably fixes the multi-way pipe fitting 120 or the supply pipeline 130 without damaging the multi-way pipe fitting 120 or the supply pipeline 130.

[0142] Exemplarily, the pump housing 151 may be provided with a fixing foot, which has a through hole, and the installation position of the clothing processing device 300 corresponding to the pump housing 151 is provided with a threaded hole. After aligning the through hole with the threaded hole, a bolt is passed through the through hole and screwed into the threaded hole to fix the pump housing 151 in the clothing processing device 300, thereby ensuring that the pumping assembly 150 works stably and avoiding vibration of the pumping assembly 150 during the pumping process, which may cause the pumping assembly 150 to be misaligned.

[0143] In some examples, the pump body 152 is a peristaltic pump.

[0144] It is understandable that a peristaltic pump can be used for the pump body 152. The use of a peristaltic pump allows the detergent to only contact the pump tube and not the pump body 152, thereby avoiding contamination of the detergent and ensuring the cleaning effect of the detergent on clothes. The peristaltic pump has high repeatability and high stability accuracy. The peristaltic pump has good sealing and low shear force, and is suitable for pumping a variety of detergents. The peristaltic pump has no valves and seals, and the maintenance of the peristaltic pump is simple. The peristaltic pump is bidirectional, and the detergent can be pumped from the liquid storage component 110 to the second liquid inlet pipe section 122, or the detergent can be pumped from the second liquid inlet pipe section 122 to the liquid storage component 110.

[0145] In some examples, the control unit includes: a first control module, for responding to a cleaning agent delivery instruction, controlling the pumping assembly 150 to pump fluid from the liquid storage assembly 110 toward the second liquid inlet pipe section 122 until the fluid output of the pumping assembly 150 reaches a preset output; a second control module, for responding to a backwash start instruction, controlling the pumping assembly 150 to pump fluid from the second liquid inlet pipe section 122 toward the liquid storage assembly 110; and a third control module, for responding to a backwash termination instruction, controlling the pumping assembly 150 to shut down.

[0146] It is understandable that the control unit may be provided with a first control module, a second control module and a third control module to control the pumping direction of the pumping assembly 150. Specifically, the first control module may respond to the detergent delivery instruction. Specifically, when detergent is stored in the liquid storage assembly 110, after the detergent delivery instruction is issued, the first control module responds to the detergent delivery instruction, the pumping assembly 150 is started, and the first control module controls the pumping assembly 150 to pump the detergent from the liquid storage assembly 110 to the direction of the second liquid inlet pipe section 122. The pumping assembly 150 provides kinetic energy for the detergent, and is transported from the liquid storage assembly 110 along the delivery pipeline 140 to the second liquid inlet pipe section 122. At the same time, the cleaning water is transported from the water source along the water inlet pipe section to the first liquid inlet pipe section 121. After the cleaning water and the cleaning agent are fully mixed in the liquid outlet pipe section 123 and the liquid injection pipe section, they are transported to the clothing processing chamber of the clothing processing device. When it is detected that the cleaning agent output of the pumping component 150 reaches the preset output, the cleaning agent delivery instruction can be stopped and the pumping component 150 stops the pumping operation.

[0147] For example, a flow meter may be provided at the second liquid inlet pipe section 122 to detect the flow rate of the cleaning agent pumped by the pumping assembly 150 to count the output amount of the cleaning agent.

[0148] The second control module may respond to a backwash start instruction. Specifically, after the backwash start instruction is issued, the second control module responds to the backwash start instruction, the pumping component 150 is started, and the second control module controls the pumping component 150 to pump fluid from the second liquid inlet pipe section 122 to the direction of the liquid storage component 110 to flush the residual detergent in the second liquid inlet pipe section 122 and the delivery pipeline 140. The pumped fluid may be cleaning water and / or a mixed liquid in the clothing processing chamber. The cleaning water may be transported from the water source along the water inlet pipe section to the first liquid inlet pipe section 121, and the pumping component 150 pumps the cleaning water in the first liquid inlet pipe section 121 to the second liquid inlet pipe section 122 to flush the residual cleaning agent. The mixed liquid in the clothing processing chamber is a cleaning liquid mixed with cleaning water and cleaning agent. The cleaning liquid can be transported to the second liquid inlet pipe section 122 along the liquid injection pipe section and the liquid outlet pipe section 123 to flush the residual cleaning agent transported to the second liquid inlet pipe section 122 by the liquid injection pipe section and the liquid outlet pipe section 123, thereby avoiding blockage of the second liquid inlet pipe section 122. When replacing the cleaning agent, the newly added cleaning agent and the cleaning agent remaining in the second liquid inlet pipe section 122 can be avoided from mixing with each other, thereby improving the user experience.

[0149] It is understandable that the backwash start instruction can be issued by the user, or can be set in the program in combination with the specific timing of the actual laundry treatment process, and is automatically issued when the laundry treatment process reaches the corresponding timing.

[0150] Specifically, the pumping assembly 150 responds to the backwash start instruction, and the pumping assembly 150 pumps the cleaning water at the first liquid inlet pipe section 121 and / or the cleaning liquid at the liquid outlet pipe section 123 to the second liquid inlet pipe section 122 to flush the cleaning agent remaining in the second liquid inlet pipe section 122 to avoid blockage of the second liquid inlet pipe section 122.

[0151] Exemplarily, the timing may be before the first water inflow into the clothing processing chamber is completed. It is understandable that when the clothing processing device processes clothing, it is necessary to deliver cleaning water multiple times. Before the first water inflow into the clothing processing chamber is completed, the pumping assembly 150 responds to the backwash start instruction, and the pumping assembly 150 pumps the cleaning water at the first liquid inlet pipe section 121 and / or the cleaning liquid at the liquid outlet pipe section 123 to the second liquid inlet pipe section 122 to flush the residual cleaning agent in the second liquid inlet pipe section 122 to avoid clogging of the second liquid inlet pipe section 122.

[0152] Exemplarily, the timing may be when the clothing processing chamber is inflowing with water for the second time and during the subsequent water inflows, the pumping component 150 responds to the backwash start instruction, and the pumping component 150 pumps the cleaning water at the first liquid inlet pipe section 121 and / or the cleaning liquid at the liquid outlet pipe section 123 to the second liquid inlet pipe section 122 to flush the cleaning agent remaining in the second liquid inlet pipe section 122 to avoid blockage of the second liquid inlet pipe section 122.

[0153] Exemplarily, the timing may be before the current washing process of the clothing processing chamber is completed, the pumping component 150 responds to the backwash start instruction, and the pumping component 150 pumps the cleaning water at the first liquid inlet pipe section 121 and / or the cleaning liquid at the liquid outlet pipe section 123 to the second liquid inlet pipe section 122 to flush the residual cleaning agent in the second liquid inlet pipe section 122 to avoid blockage of the second liquid inlet pipe section 122.

[0154] Exemplarily, the timing may be before the clothing processing equipment is shut down, and the pumping component 150 responds to the backwash start instruction, and the pumping component 150 pumps the cleaning water at the first liquid inlet pipe section 121 and / or the cleaning liquid at the liquid outlet pipe section 123 to the second liquid inlet pipe section 122 to flush the residual cleaning agent in the second liquid inlet pipe section 122 to avoid blockage of the second liquid inlet pipe section 122.

[0155] Exemplarily, the timing may be after the clothing processing equipment is turned off, the dispensing system 100 may operate independently, and the pumping component 150 responds to the backwash start instruction, and the pumping component 150 pumps the cleaning water at the first liquid inlet pipe section 121 to the second liquid inlet pipe section 122 to flush the residual cleaning agent in the second liquid inlet pipe section 122 to avoid blockage of the second liquid inlet pipe section 122.

[0156] The third control module may control the pumping assembly 150 to close in response to the backwashing termination instruction. Specifically, when the pumping assembly 150 performs the backwashing operation, the residual cleaning agent in the second liquid inlet pipe section 122 may be reduced. When it is determined that the backwashing operation is completed, a backwashing termination instruction may be issued. The third control module controls the pumping assembly 150 to close in response to the backwashing termination instruction, and stops the backwashing operation.

[0157] In some examples, the control unit further includes: a first generation module for generating the backwash start instruction in response to a power off instruction; and / or a second generation module for generating the backwash start instruction in response to a clothing processing termination instruction; and / or a third generation module for generating the backwash start instruction when the fluid output reaches the preset output.

[0158] It is understandable that the control unit is further provided with a first generation module, a second generation module and a third generation module. Among them, the first generation module can respond to a power-off instruction. Specifically, after a power-off instruction is issued to the clothing processing device, the power of the clothing processing device is turned off, and the delivery system 100 can operate independently. The first generation module responds to the power-off instruction and generates a backwash start instruction. The pumping component 150 pumps the cleaning water at the first liquid inlet pipe section 121 to the second liquid inlet pipe section 122 to flush the residual cleaning agent in the second liquid inlet pipe section 122 to avoid blockage of the second liquid inlet pipe section 122.

[0159] The second generation module may respond to the clothing treatment termination instruction. Specifically, after the clothing treatment device completes the clothing treatment, the second generation module responds to the clothing treatment termination instruction and generates a backwashing start instruction, and the pumping component 150 pumps the cleaning water at the first liquid inlet pipe section 121 to the second liquid inlet pipe section 122 to flush the residual cleaning agent in the second liquid inlet pipe section 122 to avoid clogging of the second liquid inlet pipe section 122.

[0160] The third generation module can generate a backwash instruction according to the output of the detergent. Specifically, in the detergent delivery stage, the preset output of the detergent required for washing clothes can be determined according to the amount of clothes processed and the user setting mode. The pumping component 150 pumps the detergent in the liquid storage component 110 to the second liquid inlet pipe section 122, and then enters the clothing processing chamber along the liquid outlet pipe section 123 and the liquid injection pipe section. After the output of the delivered detergent reaches the preset output, the pumping of the detergent is stopped, and a backwash instruction is generated. The pumping component 150 pumps the cleaning water at the first liquid inlet pipe section 121 and / or the cleaning liquid at the liquid outlet pipe section 123 to the second liquid inlet pipe section 122 to flush the residual detergent in the second liquid inlet pipe section 122 to avoid clogging of the second liquid inlet pipe section 122. The preset output can be set by the user. If the user does not set it, it is set according to the factory default setting of the clothing processing equipment. For example, the preset output can be set to 20 ml.

[0161] In some examples, the control unit further includes: a fourth generation module for generating the backwash termination instruction when the running time of the pumping component 150 based on the backwash start instruction reaches a preset time; and / or a fifth generation module for generating the backwash termination instruction according to the running pressure of the pumping component 150 when the pumping component 150 runs based on the backwash start instruction, and the running pressure is positively correlated with the viscosity of the fluid pumped by the pumping component 150; and / or a sixth generation module for generating the backwash termination instruction according to the running speed of the pumping component 150 when the pumping component 150 runs based on the backwash start instruction, and the running speed is positively correlated with the viscosity of the fluid pumped by the pumping component 150.

[0162] It is understandable that the control unit is further provided with a fourth generation module, a fifth generation module and a sixth generation module. The backwashing termination instruction can be generated by the fourth generation module, the fifth generation module and the sixth generation module.

[0163] Among them, the fourth generation module can generate a backwash termination instruction based on the running time of the pumping component 150 based on the backwash start instruction. Specifically, when the pumping component 150 runs for a preset time based on the backwash start instruction, it can be considered that the pumping component 150 pumps the cleaning water and / or cleaning liquid into the second liquid inlet pipe section 122, and has removed the residual cleaning agent in the second liquid inlet pipe section 122 to within the set range, to the extent that the second liquid inlet pipe section 122 will not be blocked. The fourth generation module generates a backwash termination instruction, so that the pumping component 150 stops backwashing pumping. While ensuring that the second liquid inlet pipe section 122 will not be blocked and that another cleaning agent will not cause odor contamination, energy is solved and power consumption is reduced.

[0164] The fifth generation module can generate a backwash termination instruction according to the operating pressure of the pumping component 150 when the pumping component 150 is running based on the backwash start instruction. It can be understood that the viscosity of the cleaning agent is greater than the viscosity of the cleaning water. Therefore, the operating pressure of the pumping component 150 when pumping the cleaning agent and the cleaning water is different, and the operating pressure of the pumping cleaning agent is greater than the operating pressure of the pumping cleaning water. Therefore, the degree of the backwash operation can be judged according to the operating pressure of the pumping component 150. Specifically, during the backwash operation, the operating pressure of the pump body 152 can be detected. As the backwash operation continues, the amount of cleaning agent remaining in the second liquid inlet pipe section 122 gradually decreases, and the detected operating pressure of the pump body 152 gradually decreases. When there is no residual cleaning agent in the second liquid inlet pipe section 122, the pumping component 150 shows that the operating pressure decreases and remains stable. At this time, the backwash termination instruction can be generated by the fifth generation module. The pumping component 150 stops backwashing pumping. While ensuring that the second liquid inlet pipe section 122 will not be blocked and that there will be no odor contamination when another cleaning agent is added, the energy problem is solved and power consumption is reduced.

[0165] The fifth generation module can generate a backwash termination instruction according to the running speed of the pumping component 150 when the pumping component 150 is running based on the backwash start instruction. It can be understood that the viscosity of the cleaning agent is greater than the viscosity of the cleaning water. Therefore, the running speed of the pumping component 150 when pumping the cleaning agent and the cleaning water is different, and the running speed of the pumping cleaning agent is greater than the running pressure of the pumping cleaning water to ensure the pumping effect of the cleaning agent. Therefore, the degree of backwashing operation can be judged according to the running speed of the pumping component 150. Specifically, during the backwashing operation, the running speed of the pump body 152 can be detected. As the backwashing operation continues, the amount of cleaning agent remaining in the second liquid inlet pipe section 122 gradually decreases, and the running speed of the pump body 152 detected gradually decreases. When there is no residual cleaning agent in the second liquid inlet pipe section 122, the pumping component 150 shows that the running speed decreases and remains stable. At this time, the backwash termination instruction can be generated by the fifth generation module. The pumping component 150 stops backwashing pumping. While ensuring that the second liquid inlet pipe section 122 will not be blocked and that there will be no odor contamination when another cleaning agent is added, the energy problem is solved and power consumption is reduced.

[0166] According to a second aspect of an embodiment of the present disclosure, a clothing processing device is proposed, comprising: a housing 200, formed with a water inlet interface for water intake; a processing device 300, arranged in the housing 200, forming a clothing processing chamber; a delivery system 100 as described in any one of the above technical solutions, wherein the multi-way pipe fitting 120 is arranged in the housing 200, and the liquid storage component 110 is slidably arranged in the housing 200 so that the liquid storage component 110 can extend or retract into the housing 200; wherein the first liquid inlet pipe section 121 is fluidically connected to the water inlet interface.

[0167] It is understandable that the clothing treatment device is provided with the above-mentioned delivery system 100, and therefore has all the beneficial effects of the above-mentioned delivery system 100, which will not be repeated here. The clothing treatment device is also provided with a housing 200 and a treatment device 300. Among them, the housing 200 is formed with a water inlet interface, which can be connected to a water source, and the first liquid inlet pipe section 121 can be connected to the water inlet interface through the water inlet pipe section, so that the washing water is transported from the water source to the first liquid inlet pipe section 121. The treatment device 300 is arranged in the housing 200, and the treatment device 300 is formed with a clothing treatment chamber, and the injection pipe section is connected to the clothing treatment chamber. Clothes can be put into the clothing treatment chamber, and the washing water enters the liquid outlet pipe section 123 through the first liquid inlet pipe section 121, and the detergent enters the liquid outlet pipe section 123 through the second liquid inlet pipe section 122. After the liquid outlet pipe section 123 and the injection pipe section are fully mixed, they are transported to the clothing treatment chamber. The liquid storage assembly 110 is slidably disposed on the housing 200. When detergent needs to be added to the box body 111, the liquid storage assembly 110 can be extended out of the housing 200 for easy operation by the user. When the detergent is added, the liquid storage assembly 110 can be retracted into the housing 200 so that the pump body 152 can pump the detergent into the second liquid inlet pipe section 122.

[0168] Exemplarily, the liquid storage component 110 is also provided with a panel, which is connected to the side of the box body 111 away from the delivery interface, and the panel and the outer wall of the clothing treatment device are located in the same plane. A handle or groove is provided on the panel to facilitate the user to pull the liquid storage component 110 out of the clothing treatment device, which is convenient for the subsequent detergent delivery operation. The clothing treatment device can be provided with a slide rail, and a slider is provided at the bottom of the box body 111, and the box body 111 can be slidably connected to the slide rail through the slider. This increases the smoothness of the user pulling out or pushing back the box body 111, thereby improving the user experience.

[0169] In some examples, the clothes processing device further includes: a limiting structure 400 , which is disposed on the housing 200 and is used to limit the sliding stroke of the liquid storage assembly 110 .

[0170] It is understandable that the clothing processing device is also provided with a limiting structure 400, which can limit the sliding stroke of the liquid storage component 110 to prevent the liquid storage component 110 from being pulled out too far and being pulled out of the housing, resulting in damage or inconvenience in installation, so as to facilitate user use. Exemplarily, the limiting structure 400 can be a partition, and when the liquid storage component 110 is pulled out until the partition abuts against the housing 200, the liquid storage component 110 reaches the maximum pull-out stroke.

[0171] like Fig.13 As shown, according to the third aspect of the embodiment of the present disclosure, a control method of a delivery system 100 is proposed, which is used to control the delivery system 100 as described in any one of the above technical solutions, including:

[0172] S110: In response to the cleaning agent delivery instruction, the pumping assembly 150 pumps fluid from the liquid storage assembly 110 toward the second liquid inlet pipe section 122 until the fluid output of the pump body 152 assembly reaches a preset output.

[0173] It can be understood that, when there is detergent in the liquid storage component 110, after issuing a detergent delivery instruction, the pumping component 150 is started, and the detergent is pumped by the liquid storage component 110 in the direction of the second liquid inlet pipe section 122. The pumping component 150 provides kinetic energy for the detergent, and is transported from the liquid storage component 110 along the delivery pipeline 140 to the second liquid inlet pipe section 122. At the same time, the cleaning water is transported from the water source along the water inlet pipe section to the first liquid inlet pipe section 121. After the cleaning water and the detergent are fully mixed in the liquid outlet pipe section 123 and the liquid injection pipe section, they are transported to the clothing processing chamber of the clothing processing device. When it is detected that the detergent output of the pumping component 150 reaches the preset output, the detergent delivery instruction can be stopped, and the pumping component 150 stops the pumping operation.

[0174] For example, a flow meter may be provided at the second liquid inlet pipe section 122 to detect the flow rate of the cleaning agent pumped by the pumping assembly 150 to count the output amount of the cleaning agent.

[0175] S120 : In response to the backwash start instruction, the pumping assembly 150 pumps fluid from the second liquid inlet pipe section 122 toward the liquid storage assembly 110 .

[0176] It is understandable that in response to the backwash start instruction, the pumping assembly 150 is started, and the pumping assembly 150 pumps fluid from the second liquid inlet pipe section 122 to the direction of the liquid storage assembly 110 to flush the residual detergent in the second liquid inlet pipe section 122 and the delivery pipeline 140. The pumped fluid may be cleaning water and / or a mixed liquid in the clothing treatment chamber. The cleaning water may be transported from the water source along the water inlet pipe section to the first liquid inlet pipe section 121, and the pumping assembly 150 pumps the cleaning water in the first liquid inlet pipe section 121 to the second liquid inlet pipe section 122 to flush the residual detergent. The mixed liquid in the clothing processing chamber is a cleaning liquid mixed with cleaning water and cleaning agent. The cleaning liquid can be transported to the second liquid inlet pipe section 122 along the liquid injection pipe section and the liquid outlet pipe section 123 to flush the residual cleaning agent transported to the second liquid inlet pipe section 122 by the liquid injection pipe section and the liquid outlet pipe section 123, thereby avoiding blockage of the second liquid inlet pipe section 122. When replacing the cleaning agent, the newly added cleaning agent and the cleaning agent remaining in the second liquid inlet pipe section 122 can be avoided from mixing with each other, thereby improving the user experience.

[0177] It is understandable that the backwash start instruction can be issued by the user, or can be set in the program in combination with the specific timing of the actual laundry treatment process, and is automatically issued when the laundry treatment process reaches the corresponding timing.

[0178] Specifically, the pumping assembly 150 responds to the backwash start instruction, and the pumping assembly 150 pumps the cleaning water at the first liquid inlet pipe section 121 and / or the cleaning liquid at the liquid outlet pipe section 123 to the second liquid inlet pipe section 122 to flush the cleaning agent remaining in the second liquid inlet pipe section 122 to avoid blockage of the second liquid inlet pipe section 122.

[0179] Exemplarily, the timing may be before the first water inflow into the clothing processing chamber is completed. It is understandable that when the clothing processing device processes clothing, it is necessary to deliver cleaning water multiple times. Before the first water inflow into the clothing processing chamber is completed, the pumping assembly 150 responds to the backwash start instruction, and the pumping assembly 150 pumps the cleaning water at the first liquid inlet pipe section 121 and / or the cleaning liquid at the liquid outlet pipe section 123 to the second liquid inlet pipe section 122 to flush the residual cleaning agent in the second liquid inlet pipe section 122 to avoid clogging of the second liquid inlet pipe section 122.

[0180] Exemplarily, the timing may be when the clothing processing chamber is inflowing with water for the second time and during the subsequent water inflows, the pumping component 150 responds to the backwash start instruction, and the pumping component 150 pumps the cleaning water at the first liquid inlet pipe section 121 and / or the cleaning liquid at the liquid outlet pipe section 123 to the second liquid inlet pipe section 122 to flush the cleaning agent remaining in the second liquid inlet pipe section 122 to avoid blockage of the second liquid inlet pipe section 122.

[0181] Exemplarily, the timing may be before the current washing process of the clothing processing chamber is completed, the pumping component 150 responds to the backwash start instruction, and the pumping component 150 pumps the cleaning water at the first liquid inlet pipe section 121 and / or the cleaning liquid at the liquid outlet pipe section 123 to the second liquid inlet pipe section 122 to flush the residual cleaning agent in the second liquid inlet pipe section 122 to avoid blockage of the second liquid inlet pipe section 122.

[0182] Exemplarily, the timing may be before the clothing processing equipment is shut down, and the pumping component 150 responds to the backwash start instruction, and the pumping component 150 pumps the cleaning water at the first liquid inlet pipe section 121 and / or the cleaning liquid at the liquid outlet pipe section 123 to the second liquid inlet pipe section 122 to flush the residual cleaning agent in the second liquid inlet pipe section 122 to avoid blockage of the second liquid inlet pipe section 122.

[0183] Exemplarily, the timing may be after the clothing processing equipment is turned off, the dispensing system 100 may operate independently, and the pumping component 150 responds to the backwash start instruction, and the pumping component 150 pumps the cleaning water at the first liquid inlet pipe section 121 to the second liquid inlet pipe section 122 to flush the residual cleaning agent in the second liquid inlet pipe section 122 to avoid blockage of the second liquid inlet pipe section 122.

[0184] S130: In response to the backwash termination instruction, the pumping assembly 150 is turned off.

[0185] It can be understood that when the pumping component 150 performs a backwashing operation, the residual cleaning agent in the second liquid inlet pipe section 122 can be reduced. When it is determined that the backwashing operation is completed, a backwashing termination instruction can be issued. In response to the backwashing termination instruction, the pumping component 150 is controlled to close and the backwashing operation is stopped. While ensuring that the second liquid inlet pipe section 122 will not be blocked and that there will be no odor when another cleaning liquid is added, the energy problem is solved and power consumption is reduced.

[0186] In some examples, the control method of the delivery system 100 further includes: generating the backwash start instruction in response to a power off instruction.

[0187] It can be understood that after a power-off command is issued to the clothing processing device, the power of the clothing processing device is turned off, and the dispensing system 100 can operate independently, respond to the power-off command, and generate a backwash start command. The pumping component 150 pumps the cleaning water at the first liquid inlet pipe section 121 to the second liquid inlet pipe section 122 to flush the residual cleaning agent in the second liquid inlet pipe section 122 to avoid blockage of the second liquid inlet pipe section 122.

[0188] In some examples, the control method of the delivery system 100 further includes: generating the backwash start instruction when the fluid output reaches the preset output.

[0189] It is understandable that a backwash instruction can be generated according to the output of the detergent. Specifically, during the detergent delivery stage, the preset output of the detergent required for washing clothes can be determined according to the amount of clothes processed and the user-set mode. The pumping component 150 pumps the detergent in the liquid storage component 110 to the second liquid inlet pipe section 122, and then enters the clothing processing chamber along the liquid outlet pipe section 123 and the liquid injection pipe section. After the output of the delivered detergent reaches the preset output, the pumping of the detergent is stopped, and a backwash instruction is generated. The pumping component 150 pumps the cleaning water at the first liquid inlet pipe section 121 and / or the cleaning liquid at the liquid outlet pipe section 123 to the second liquid inlet pipe section 122 to flush the residual detergent in the second liquid inlet pipe section 122 to avoid clogging of the second liquid inlet pipe section 122. The preset output can be set by the user. If the user does not set it, it is set according to the factory default setting of the clothing processing device. For example, the preset output can be set to 20 ml.

[0190] In some examples, the control method of the above-mentioned dosing system 100 also includes: when the operating time of the above-mentioned pumping component 150 based on the above-mentioned backwash start instruction reaches a preset time, generating the above-mentioned backwash termination instruction; and / or when the above-mentioned pumping component 150 is running based on the above-mentioned backwash start instruction, generating the above-mentioned backwash termination instruction according to the operating pressure of the above-mentioned pumping component 150, and the above-mentioned operating pressure is positively correlated with the viscosity of the fluid pumped by the above-mentioned pumping component 150; and / or when the above-mentioned pumping component 150 is running based on the above-mentioned backwash start instruction, generating the above-mentioned backwash termination instruction according to the operating speed of the above-mentioned pumping component 150, and the above-mentioned operating speed is positively correlated with the viscosity of the fluid pumped by the above-mentioned pumping component 150.

[0191] It is understandable that when the running time of the pumping component 150 based on the backwash start instruction reaches the preset time, a backwash termination instruction is generated. Specifically, when the pumping component 150 runs for a preset time based on the backwash start instruction, it can be considered that the pumping component 150 pumps the cleaning water and / or cleaning liquid into the second liquid inlet pipe section 122, and has removed the residual cleaning agent in the second liquid inlet pipe section 122 to within the set range, to the extent that the second liquid inlet pipe section 122 will not be blocked. At this time, a backwash termination instruction is generated, so that the pumping component 150 stops backwashing pumping. While ensuring that the second liquid inlet pipe section 122 will not be blocked and that there will be no odor when another cleaning agent is added, energy is solved and power consumption is reduced.

[0192] It is understandable that, when the pumping assembly 150 is operated based on the backwashing start instruction, a backwashing termination instruction is generated according to the operating pressure of the pumping assembly 150. Since the viscosity of the cleaning agent is greater than the viscosity of the cleaning water. Therefore, the operating pressure of the pumping assembly 150 when pumping the cleaning agent and the cleaning water is different, and the operating pressure of the pumping cleaning agent is greater than the operating pressure of the pumping cleaning water. Therefore, the degree of the backwashing operation can be judged according to the operating pressure of the pumping assembly 150. Specifically, during the backwashing operation, the operating pressure of the pump body 152 can be detected. As the backwashing operation continues, the amount of cleaning agent remaining in the second liquid inlet pipe section 122 gradually decreases, and the detected operating pressure of the pump body 152 gradually decreases. When there is no residual cleaning agent in the second liquid inlet pipe section 122, the pumping assembly 150 shows that the operating pressure decreases and remains stable. At this time, a backwashing termination instruction can be generated. The pumping assembly 150 stops backwashing pumping. While ensuring that the second liquid inlet pipe section 122 will not be blocked and that there will be no odor contamination when another cleaning agent is added, the energy problem is solved and power consumption is reduced.

[0193] It is understandable that, when the pumping assembly 150 is running based on the backwash start instruction, a backwash termination instruction can be generated according to the running speed of the pumping assembly 150. Since the viscosity of the cleaning agent is greater than the viscosity of the cleaning water. Therefore, the running speed of the pumping assembly 150 when pumping the cleaning agent and the cleaning water is different, and the running speed of the pumping cleaning agent is greater than the running pressure of the pumping cleaning water to ensure the pumping effect of the cleaning agent. Therefore, the degree of backwashing operation can be judged according to the running speed of the pumping assembly 150. Specifically, during the backwashing operation, the running speed of the pump body 152 can be detected. As the backwashing operation continues, the amount of cleaning agent remaining in the second liquid inlet pipe section 122 gradually decreases, and the running speed of the pump body 152 detected gradually decreases. When there is no residual cleaning agent in the second liquid inlet pipe section 122, the pumping assembly 150 shows that the running speed decreases and remains stable. At this time, a backwash termination instruction can be generated. The pumping assembly 150 stops backwashing pumping. While ensuring that the second liquid inlet pipe section 122 will not be blocked and that there will be no odor contamination when another cleaning agent is added, the energy problem is solved and power consumption is reduced.

[0194] like Fig.14 As shown, according to the fourth aspect of the present application, a computer-readable storage medium 401 is proposed, and the computer-readable storage medium 401 stores a computer program 402 to implement the control method described in any of the above technical solutions.

[0195] The computer-readable storage medium 401 provided in the embodiment of the present application, in response to the cleaning agent delivery instruction, the pumping component 150 pumps fluid from the liquid storage component 110 to the direction of the second liquid inlet pipe section 122 until the fluid output of the pump body 152 component reaches the preset output. In response to the backwash start instruction, the pumping component 150 pumps fluid from the second liquid inlet pipe section 122 to the direction of the liquid storage component 110; in response to the backwash termination instruction, the pumping component 150 is closed. This ensures that the second liquid inlet pipe section 122 will not be blocked by the cleaning agent, and that the delivery of another cleaning agent will not cause odor, while solving the energy problem and reducing power consumption.

[0196] Based on this understanding, the technical solution of the present application can be embodied in the form of a software product, which can be stored in a non-volatile storage medium (which can be a CD-ROM, a USB flash drive, a mobile hard disk, etc.), and includes a number of instructions for enabling a computer device (which can be a personal computer, a server, or a network device, etc.) to execute the methods described in each implementation scenario of the present application.

[0197] like Fig.15 As shown, according to the fifth aspect of the present application, a control device 500 is proposed, comprising: a memory 501, storing a computer program; a processor 502, executing the computer program; wherein, when the processor 502 executes the computer program, it implements the control method described in any of the above technical solutions.

[0198] The control device 500 provided in the embodiment of the present application, in response to the cleaning agent delivery instruction, the pumping component 150 pumps fluid from the liquid storage component 110 to the direction of the second liquid inlet pipe section 122 until the fluid output of the pump body 152 component reaches the preset output. In response to the backwash start instruction, the pumping component 150 pumps fluid from the second liquid inlet pipe section 122 to the direction of the liquid storage component 110; in response to the backwash termination instruction, the pumping component 150 is closed. This ensures that the second liquid inlet pipe section 122 will not be blocked by the cleaning agent, and that the delivery of another cleaning agent will not cause odor, while solving the energy problem and reducing power consumption.

[0199] In some examples, the control device may also include a user interface, a network interface, a camera, a radio frequency (RF) circuit, a sensor, an audio circuit, a WI-FI module, etc. The user interface may include a display, an input unit such as a keyboard, etc., and the optional user interface may also include a USB interface, a card reader interface, etc. The network interface may optionally include a standard wired interface, a wireless interface (such as a WI-FI interface), etc.

[0200] In an exemplary embodiment, the control device may further include an input / output interface and a display device, wherein each functional unit may communicate with each other via a bus.
