[0055] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0056] The embodiments of the present application provide a dispensing device and a clothing processing device to solve the problem that the detergent box of the existing washing machine includes a pull-out drawer, which may cause the washing machine to leak if the drawer is not installed in place. The following will be explained with reference to the accompanying drawings.

[0057] The delivery device provided in the embodiment of the present application is applied to a clothes processing device, and the clothes processing device includes a washing drum. Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of the delivery device provided in the embodiment of the present application, Figure 2 for Figure 1 In the cross-sectional view at AA, the delivery device includes a water inlet valve 1, a detergent box 2, a sealing cover 3 and a spray pipe. The detergent box 2 is provided with a connected liquid storage chamber 21 and a delivery port 22, and the liquid storage chamber 21 is used to store detergent; the sealing cover 3 is a detachable cover provided at the delivery port 22; the spray pipe includes a connected pipe body 4 and a liquid extraction part, the pipe body 4 is connected to the water inlet valve 1 and the washing tub, and the liquid extraction part is located between the water inlet valve 1 and the washing tub along the flow direction of the liquid, and the liquid extraction part is used to extract the detergent in the liquid storage chamber 21 into the pipe body 4.

[0058] The dispensing device provided in the embodiment of the present application only needs to remove the sealing cover 3 on the detergent box 2 when adding detergent, and there is no need to pull out the detergent box 2, that is, the position of the liquid storage chamber 21 for storing detergent in the detergent box 2 remains unchanged, and no matter whether the user installs the sealing cover 3 after opening the sealing cover 3, it will not affect the extraction of detergent from the liquid storage chamber 21 by the liquid pumping unit; at the same time, the water inlet valve 1 directly feeds water into the pipe body 4 of the spray pipe, and the liquid pumping unit extracts the detergent in the detergent box 2 into the pipe body 4 to mix with water, which not only realizes the dispensing of detergent, but also avoids the problem of water inflow into the detergent box 2 causing the detergent box 2 to leak.

[0059] Optionally, see Figure 2 , Figure 2 for Figure 1 In the cross-sectional view at AA, the detergent box 2 is further provided with a delivery chamber 23, which is spaced apart from the liquid storage chamber 21, and the liquid pumping part connects the delivery chamber 23 and the tube body 4; the delivery device further includes a delivery pump 6, which connects the liquid storage chamber 21 and the delivery chamber 23, and is used to pump part of the detergent in the liquid storage chamber 21 into the delivery chamber 23. In some examples, the delivery pump 6 can be a peristaltic pump.

[0060] By providing the delivery chamber 23, the pumping part is prevented from being directly connected to the liquid storage chamber 21, and the water introduced into the pipe body 4 of the spray pipe by the water inlet valve 1 is prevented from entering the liquid storage chamber 21 from the pumping part due to damage of the pumping part or other reasons, resulting in the detergent stored in the liquid storage chamber 21 being contaminated. At the same time, part of the detergent in the liquid storage chamber 21 is pumped into the delivery chamber 23 by the delivery pump 6, so that it can be pumped as needed, and the amount of extraction only needs to meet the delivery amount this time, which will realize the accurate delivery of detergent and avoid waste. The delivery chamber 23 provides a temporary storage space for the extracted detergent.

[0061] That is, the liquid storage chamber 21 is used to store detergent, and the delivery chamber 23 is used to store the detergent required for this delivery. The liquid storage chamber 21 and the delivery pump 6 are used in conjunction to realize automatic delivery of detergent, thereby avoiding the need for users to add detergent every time washing, saving operation time, and simplifying the method of use. At the same time, the delivery pump 6 ensures accurate control of the delivery amount, thereby avoiding excessive addition of detergent or some influence on the washing effect due to lack of human experience.

[0062] In some examples, the delivery cavity 23 may be disposed below the liquid storage cavity 21 along the direction of gravity; in other examples, the delivery cavity 23 may also be disposed adjacent to the liquid storage cavity 21 on the same horizontal plane.

[0063] Optionally, see Figure 3 , Figure 3 for Figure 2 In the cross-sectional view at DD in the middle, the liquid storage chambers 21 include multiple and spaced apart arrangements, each liquid storage chamber 21 is used to store a detergent, and multiple delivery ports 22 are provided correspondingly, each liquid storage chamber 21 is connected to a delivery port 22, and the delivery pump 6 includes multiple liquid pumping ends 61 and a liquid outlet end 62, each liquid pumping end 61 is connected to a liquid storage chamber 21, and the liquid outlet end 62 is connected to the delivery chamber 23. Among them, the sealing cover 3 also includes multiple, and each delivery port 22 is equipped with a sealing cover 3 to seal the delivery port 22.

[0064] By setting up multiple liquid storage chambers 21 to store different detergents, such as washing powder, laundry liquid, softener, disinfectant, etc., different types of detergents can be stored separately. When a certain type of detergent needs to be added, a preset volume of the detergent is extracted into the delivery chamber 23 through the corresponding liquid extraction end 61 of the delivery pump 6. When two or more detergents need to be added at the same time, a preset volume of each detergent can be extracted into the delivery chamber 23 through the corresponding liquid extraction end 61 of the delivery pump 6, so that the two or more detergents can be pre-mixed in the delivery chamber 23 for a certain period of time, and then extracted into the pipe body 4 of the spray pipe through the liquid extraction part, thereby increasing the mixing time of multiple detergents and improving the washing effect.

[0065] The number of the liquid storage chambers 21 is not further limited here, for example, it can be two, three, five, etc.

[0066] Optionally, each liquid storage cavity 21 is provided with a liquid extraction port, and the liquid extraction end 61 of the delivery pump 6 is extended into the liquid storage cavity 21 through the liquid extraction port. Further, a sealing ring is provided on the outer periphery of the liquid extraction end 61 to prevent liquid leakage.

[0067] Optionally, the dispensing device provided in the embodiment of the present application further includes a liquid level detection component 7, which is used to detect the liquid level in the liquid storage chamber 21 and alarm when the liquid level is lower than a preset value. By providing the liquid level detection component 7, when the amount of detergent in the liquid storage chamber 21 is low, the user is prompted to add detergent in time to avoid affecting the washing effect due to low detergent content.

[0068] Optionally, the liquid level detection assembly 7 includes a positioning column 71, a liquid level float 72 and a detection member 73. The positioning column 71 is arranged in the liquid storage chamber 21; the liquid level float 72 is sleeved on the positioning column 71, and the liquid level float 72 is used to float on the surface of the detergent; the detection member 73 is arranged on the periphery of the detergent box 2 and corresponds to the positioning column 71, and the detection member 73 is used to detect the position of the liquid level float 72 and alarm when the liquid level float 72 reaches a preset position. Among them, the positioning column 71 is extended along the height direction of the liquid storage chamber 21, that is, the positioning column 71 is extended along the gravity direction.

[0069] The alarm method of the detection member 73 is not further limited here. In some examples, the washing machine includes a main board, and the detection member 73 is connected to the main board in communication. When the liquid level float 72 reaches a preset position, the detection member 73 sends an alarm signal to the main board. After receiving the alarm signal, the main board can send an acoustic signal, a light signal, or a vibration to prompt the user to add detergent. In other examples, the detection member 73 can be connected to a mobile device in communication. When the liquid level float 72 reaches a preset position, the detection member 73 directly sends an alarm prompt to the mobile device, which can be a mobile phone, a tablet computer, or a PAD.

[0070] In some examples, the liquid level float 72 is magnetic, and the detection member 73 is a magnetic signal detection device. The magnetic signal detection device determines the distance between the liquid level float 72 and the magnetic signal detection device by detecting the surrounding magnetic field strength. For example, when the magnetic signal detection device is located at the bottom of the positioning column 71 along the gravity direction, the liquid level float 72 will gradually approach the magnetic signal detection device as the liquid level in the liquid storage chamber 21 decreases. When the distance between the liquid level float 72 and the magnetic signal detection device is less than or equal to a certain set value, that is, when the magnetic signal strength detected by the magnetic signal detection device is greater than or equal to a certain specific value, the magnetic signal detection device will alarm. Alternatively, when the magnetic signal detection device is located at the top of the positioning column 71 along the gravity direction, the liquid level float 72 will gradually move away from the magnetic signal detection device as the liquid level in the liquid storage chamber 21 decreases. When the distance between the liquid level float 72 and the magnetic signal detection device is greater than or equal to a certain set value, that is, when the magnetic signal strength detected by the magnetic signal detection device is less than or equal to a certain specific value, the magnetic signal detection device will alarm.

[0071] When there are multiple liquid storage chambers 21 , a liquid level detection component 7 may be disposed in each liquid storage chamber 21 to detect the liquid level in the corresponding liquid storage chamber 21 .

[0072] Optionally, see Figure 4 and Figure 5 , Figure 4 for Figure 1 Cross-sectional view at the middle BB, Figure 5 This is a front view of the spray head of the delivery device provided in the embodiment of the present application. The delivery device provided in the embodiment of the present application also includes a spray head 8, one end of the spray head 8 is connected to the pipe body 4, and the other end is arranged toward the washing tub; the spray head 8 is recessed with a spray slot 81 on the side facing the washing tub, and the cross-sectional area of ​​the spray slot 81 gradually decreases toward the end away from the washing tub, and a flow cavity 82 is arranged inside the spray head 8, one end of the flow cavity 82 is connected to the pipe body 4, and the other end passes through the spray slot 81 and forms a nozzle 83; wherein the flow area of ​​the flow cavity 82 gradually decreases toward the end close to the spray slot 81. wherein the cross-sectional area of ​​the spray slot 81 refers to the cross section of the spray slot 81 on a plane perpendicular to the flow direction of the liquid in the spray head 8.

[0073] Since the cross-sectional area of ​​the spray slot 81 gradually decreases toward the end away from the washing tub, the diameter of the nozzle 83 gradually increases toward the side close to the washing tub, thereby increasing the spray range of the nozzle 83. Since the flow area of ​​the flow chamber 82 gradually decreases toward the end close to the spray slot 81, the pressure in the flow chamber 82 gradually increases toward the end close to the nozzle 83, thereby increasing the pressure at the nozzle 83, so that the pressure at the nozzle 83 is larger and the spray area is also larger.

[0074] In some examples, the longitudinal section of the spray slot 81 may be triangular, and the end of the flow cavity 82 close to the nozzle 83 may be hemispherical, so that the contour line of the nozzle 83 is roughly elliptical, and the spray shape of the nozzle 83 is roughly fan-shaped.

[0075] The position of the spray head 8 is not further limited here. In some examples, the spray head 8 can extend through the door seal of the washing machine and be positioned above the front end of the washing drum, and spray toward the inner drum of the washing drum; in other examples, the spray head 8 can extend between the outer drum and the inner drum.

[0076] Optionally, the tube body 4 includes a first tube body 41 and a second tube body 42, see Figure 8 , Figure 8 The schematic diagram of the structure of the liquid extraction part of the delivery device provided in the embodiment of the present application, the liquid extraction part includes a venturi tube 5, the venturi tube 5 is connected between the first tube body 41 and the second tube body 42, the venturi tube 5 is also provided with a negative pressure port 521, and the negative pressure port 521 is connected to the delivery chamber 23.

[0077] Furthermore, the venturi tube 5 includes a first pipe section 51, a second pipe section 52 and a third pipe section 53, wherein the diameter of the second pipe section 52 is smaller than the diameters of the first pipe section 51 and the third pipe section 53, and the negative pressure port 521 is arranged on the second pipe section 52, so that after the water in the first tube body 41 enters the venturi tube 5, a negative pressure will be formed in the second pipe section 52, thereby absorbing the detergent in the delivery chamber 23, thereby realizing automatic absorption of the detergent in the delivery chamber 23, without the need for an additional power source, saving energy and reducing the cost of use.

[0078] Optionally, a foaming part 43 is provided in the tube body 4, and the foaming part 43 is located downstream of the liquid extraction part, and the foaming part 43 is used to impact and foam the liquid flowing through to increase the foam content in the liquid. By increasing the foam content in the liquid, the dissolution rate of the detergent is increased, and the washing effect is optimized.

[0079] The structure of the foaming portion 43 is not further limited here. In some examples, please refer to Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the structure of the foaming part of the dispensing device provided in an embodiment of the present application. Figure 7 for Figure 1 In the cross-sectional view at CC, the foaming portion 43 includes a foaming ring, which is arranged in the tube body 4 and downstream of the liquid extraction portion. A plurality of groups of foaming fins are arranged at intervals in the extension direction of the foaming ring, and each group of foaming fins includes a plurality of foaming strips arranged at intervals around the circumference of the foaming ring. Further, the foaming ring may include a plurality of foaming rings and be arranged at intervals along the extension direction of the tube body 4 to further increase the foaming effect.

[0080] In other examples, the foaming portion 43 includes an ultrasonic foamer, that is, foaming is performed by ultrasonic waves. Since ultrasonic waves are sound waves with a relatively high vibration frequency, the frequency range is from 20kHz to 10MHz. When the energy of the ultrasonic waves is high enough, that is, it exceeds the cavitation threshold of the liquid, ultrasonic cavitation will occur. Since sound waves are longitudinal waves, during the propagation of ultrasonic waves in the liquid, a compression phase and a rarefaction phase will be alternately generated in the liquid. The high negative pressure conditions formed by the rarefaction phase can make the gas in the liquid supersaturated and precipitate, generating a large number of microbubbles.

[0081] Optionally, the sealing cover 3 can be screwed, plugged, or snap-connected to the loading port 22.

[0082] Optionally, a diverter ring 44 is further provided in the tube body 4. The diverter ring 44 is located in the sprinkler head 8. A plurality of diverter holes are spaced apart and penetrated on the diverter ring 44. Each diverter hole can allow liquid to pass through. When the liquid passes through the diverter ring 44, it hits the diverter ring 44 and passes through the diverter hole, thereby increasing the foam content in the liquid and further improving the foaming effect.

[0083] The embodiment of the present application further provides a clothes processing device, comprising a washing tub and the above-mentioned feeding device. The feeding device is used to feed liquid into the washing tub.

[0084] Optionally, the laundry processing device provided in the embodiment of the present application further includes a box body 9 and a delivery cover 10. The washing tub and the delivery device of the box body 9 are both arranged in the box body 9, see Fig. 9 , Fig.10 and Fig.11 , Fig. 9 A cross-sectional view showing the connection between the delivery device and the delivery cover provided in an embodiment of the present application. Fig.10 A schematic diagram of a clothes handling device provided in an embodiment of the present application with a placing cover in a closed state, Fig.11 The schematic diagram of the clothing processing device provided in the embodiment of the present application shows that the delivery cover is in an open state, and an adjacent mounting port 91 and a first magnetic attraction portion 92 are provided on the box body 9, and the delivery port 22 is arranged toward the mounting port 91; the delivery cover 10 is rotatably installed on the mounting port 91, and a second magnetic attraction portion 101 is provided on the delivery cover 10. When the delivery cover 10 seals the mounting port 91, the second magnetic attraction portion 101 is magnetically attracted to the first magnetic attraction portion 92.

[0085] By providing the second magnetic portion 101 and the first magnetic portion 92, when the delivery cover 10 seals the installation opening 91, the delivery cover 10 is auxiliary locked by the magnetic attraction between the second magnetic portion 101 and the first magnetic portion 92, so as to prevent the delivery cover 10 from being separated from the installation opening 91 by a slight external force, so that dust falls on the installation opening 91. At the same time, due to the magnetic attraction between the second magnetic portion 101 and the first magnetic portion 92, if the user does not close the delivery cover 10 in place with little force, so that the delivery cover 10 rotates to a smaller angle with the plane where the installation opening 91 is located, the second magnetic portion 101 and the first magnetic portion 92 are automatically attracted to realize the automatic closing of the delivery cover 10, so as to avoid the installation opening 91 being exposed.

[0086] In some examples, the first magnetic attraction portion 92 and the second magnetic attraction portion 101 may both be magnets or electromagnets.

[0087] Optionally, the bottom of the dispensing cover 10 can be hinged to the lower half of the side wall of the box body 9 surrounding the installation opening 91, and the second magnetic attraction portion 101 is provided on the inner side of the top of the dispensing cover 10, and the first magnetic attraction portion 92 is correspondingly arranged on the inner side of the upper half of the side wall of the box body 9 surrounding the installation opening 91. The dispensing cover 10 rotates toward the outside of the box body 9 to open the installation opening 91. At this time, the user can open the sealing cover 3 to add detergent, and the dispensing cover 10 rotates toward the inside of the box body 9 to seal the installation opening 91.
