DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0038] In the various specific technical features described in the specific embodiments, without contradiction, they can be combined in any suitable manner. For example, different embodiments and technical solutions can be formed by combining different specific technical features. To avoid unnecessary repetition, various possible combination methods of the specific technical features in the present utility model will not be described separately.

[0039] In the following description, the terms "first\second\..." only distinguish different objects and do not indicate that there are the same or related aspects between the objects. It should be understood that the described orientation descriptions "above", "below", "outside", "inside" are all orientations in the normal use state, and the "left" and "right" directions represent the left and right directions shown in the specific corresponding schematic diagram, which can be the left and right directions in the normal use state or not.

[0040] It should be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including that element. The term "connection" includes both direct connection and indirect connection without special explanation.

[0041] In some specific embodiments, the liquid dispensing device can be used to hold detergent and dispense a set type and set amount of detergent in a set program step during the washing process. The detergent can include a main detergent or can include a main detergent and an auxiliary detergent. The auxiliary detergent can be a fabric softener. Usually, the liquid dispensing device pre-mixes the detergent with water and then inputs the mixture into the washing tub of the washing machine.

[0042] In some embodiments, in combination with Figure 1 and Figure 2, the liquid dispensing device 10 includes: a liquid separation box 100, a liquid storage box 200, a liquid extraction connector 300, a liquid extraction pump 400, a liquid extraction pipe 500, a liquid return pipe 600, and a liquid extraction tube 700. A liquid separation cavity 110 is formed inside the liquid separation box 100. The liquid separation box 100 is provided with a liquid inlet 150 and a first liquid outlet 111 that communicate with the liquid separation cavity 110. Detergent can enter the liquid separation cavity through the liquid inlet 150 and be output from the first liquid outlet 111. Optionally, the liquid separation box 100 also has a water inlet, and the detergent can be mixed with water in the liquid separation box 100 and then output from the first liquid outlet 111, so that the detergent can contact the clothes in the washing tub of the washing machine more fully. A liquid storage cavity 210 is formed inside the liquid storage box 200. The liquid storage cavity 210 is used to store detergent. The liquid storage box 200 is at least partially located inside the liquid separation cavity 110, and the liquid storage box 200 can slide relative to the liquid separation box 100 in a first direction (the first direction is as shown by the arrow in Figure 1 and Figure 2 ). That is, the liquid storage box 200 and the liquid separation box 100 form a drawer-type structure. When it is necessary to replenish the detergent in the liquid storage box 200, the liquid storage box 200 can be pulled out from the liquid separation box 100 to facilitate replenishing the detergent into the liquid storage cavity 210. After the detergent replenishment is completed, the liquid storage box 200 can be pushed into the liquid separation box 100 so that the liquid separation box 100 can accommodate the liquid storage box 200 to reduce the occupied space of the liquid dispensing device 10; the liquid storage box 200 is provided with a second through hole 220, and the central axis of the second through hole 220 is parallel to the first direction. The liquid extraction connector 300 is detachably connected to the liquid separation box 100. The liquid extraction connector 300 includes a tubular portion 310. The first end of the tubular portion 310 is located outside the liquid separation box 100, and the second end of the tubular portion 310 opposite to the first end extends into the liquid separation cavity 110 through the first through hole 120. The second end of the tubular portion 310 extends in the first direction and can communicate with the second through hole 220. It can be understood that in the state where the liquid storage box 200 is pushed into the inside of the liquid separation box 100, the second end of the liquid extraction connector 300 can extend into the second through hole 220 so that the liquid extraction connector 300 communicates with the liquid storage cavity 210, so that the liquid extraction connector 300 can extract the detergent in the liquid storage cavity 210 to the outside of the liquid separation box 100. Among them, the liquid extraction connector 300 can be detachably connected to the liquid separation box in various ways. Exemplarily, the liquid extraction connector 300 can be detachably connected to the liquid separation box 100 through a connection structure. Exemplarily, the tubular portion 310 can be detachably connected to the liquid separation box 100 by interference fit with the first through hole 120.

[0043] Combined Figure 2 and Figure 3The liquid pump 400 is located outside the liquid separating box 100, and the liquid pumping tube 500 connects the liquid pump 400 and the first end of the tubular portion 310. The liquid pump 400 is connected to the liquid storage chamber 210 through the liquid pumping tube 500 and the tubular portion 310, so that the detergent in the liquid storage chamber 210 can be extracted. The liquid return pipe 600 connects the liquid pump 400 and the liquid inlet 150. The liquid pump 400 arranged outside the liquid separating box 100 can input the detergent from the liquid inlet 150 into the liquid separating chamber 110 through the liquid return pipe 600. The liquid pump 400 is located outside the liquid separation box 100 and is detachably connected to the liquid separation box 100 through the liquid extraction joint 300 and the liquid extraction tube 500. Compared with the structure in which the shell of the liquid extraction pump 400 is integrated with the rear part of the shell of the liquid separation box 100, the liquid extraction pump 400 can be disassembled more conveniently when the liquid extraction pump 400 needs to be repaired or replaced, thereby improving the convenience of maintenance and care of the liquid administration device 10. At the same time, the liquid extraction pump 400 is arranged outside the liquid separation box 100 and is connected to the liquid extraction joint 300 through the liquid extraction tube 500. 0 changes, the liquid pump 400 can still be applied to the liquid separating box 100, which improves the versatility of the liquid pump 400, and the liquid suction tube 500 is also exposed to the outside of the liquid separating box 100 so that a sensor can be set on the outside of the liquid suction tube 500. The sensor enables the liquid delivery device 10 to achieve more functions. For example, by setting a transmittance sensor, the bubble size or bubble density in the liquid suction tube 500 can be obtained, thereby realizing the detection of the detergent residue in the liquid storage chamber 210. For example, by setting a temperature sensor, the temperature of the detergent can be obtained.

[0044] like Figure 1 As shown, the suction tube 700 is located in the liquid storage chamber 210. The suction tube 700 has a third end and a fourth end relative to each other. The third end is connected to the second through hole 220. The suction tube 700 extends from the third end to the bottom surface of the liquid storage chamber 210 to form a fourth end, and the fourth end has a suction port. The detergent in the liquid storage chamber can be sucked through the suction tube 700, and the extracted detergent then enters the tubular portion 310.

[0045] It is understandable that the liquid separation box also has a water inlet pipe (not shown in the figure). The liquid pump pumps out a specific amount of detergent stored in the liquid storage chamber through the liquid pumping pipe and returns it to the liquid separation chamber through the return pipe. The water inlet pipe lets water into the liquid separation chamber, mixes the detergent and water in the liquid separation chamber, and then sends the mixture to the washing drum through the liquid outlet.

[0046] An embodiment of the present utility model provides a liquid dispensing device. The liquid dispensing device includes a liquid separation box having a liquid separation cavity and a liquid storage box having a liquid storage cavity. A part of the liquid storage box is located inside the liquid separation cavity and can move relative to the liquid separation box along a first direction to form a drawer-type structure. The liquid separation cavity has a liquid inlet and a first liquid outlet. The liquid dispensing device further includes a liquid extraction joint, a liquid extraction pump, a liquid extraction pipe, a liquid return pipe, and a suction pipe. The suction pipe is located inside the liquid storage cavity and is connected to a second through hole, and the end of the suction pipe extending towards the bottom of the liquid storage cavity has a suction port. The liquid extraction joint extends into the liquid separation cavity through a first through hole and can extend into the second through hole. The liquid extraction pipe connects the liquid extraction joint and the liquid extraction pump, and the liquid return pipe connects the liquid extraction pump and the liquid inlet, so that the detergent in the liquid storage cavity can flow into the liquid separation cavity. At the same time, the liquid extraction pump is located outside the liquid separation box and is detachably connected to the liquid separation box through the liquid extraction joint. By arranging the liquid extraction pump outside the liquid separation box and detachably connecting it to the liquid separation box through the liquid extraction joint and the liquid extraction pipe, compared with the structure in which the housing of the liquid extraction pump is integrated with the rear part of the housing of the liquid separation box, when the liquid extraction pump needs to be repaired or replaced, the liquid extraction pump can be disassembled more conveniently, thereby improving the convenience of maintenance and care of the liquid dispensing device. At the same time, by arranging the liquid extraction pump outside the liquid separation box and connecting it to the liquid extraction joint through the liquid extraction pipe, when the shape or appearance of the liquid separation box changes, the liquid extraction pump can still be applied to the liquid separation box, improving the versatility of the liquid extraction pump. Moreover, the liquid extraction pipe is also exposed outside the liquid separation box, so that a sensor can be arranged outside the liquid extraction pipe, and the liquid dispensing device can realize more functions through this sensor.

[0047] It can be understood that the liquid extraction pipe and the liquid return pipe can physically be the same pipe. For example, a part of the pipe is located inside the liquid extraction pump and is powered by the liquid extraction pump. The upstream of this pipe is the liquid extraction pipe, which is connected to the detergent storage container; the downstream is the liquid return pipe, which is connected to the water separation box. Exemplarily, the liquid extraction pipe and the liquid return pipe can be integrated with the liquid extraction pump physically, for example, they can be integrated with the outer shell of the liquid extraction pump. Exemplarily, one of the liquid extraction pipe and the liquid return pipe can be integrated with the outer shell of the liquid extraction pump, and the other is not integrated with the outer shell of the liquid extraction pump, so as to facilitate setting a sensor outside the liquid extraction pipe or the liquid return pipe when the liquid extraction pipe or the liquid return pipe is exposed outside the liquid separation box and the liquid extraction pump.

[0048] In some embodiments, such as Figure 4As shown, the liquid extraction joint 300 further includes a connection structure 330 on the outer periphery of the tubular portion 310. The connection structure 330 is detachably fixed to the outer surface of the liquid separation box 100 through a connecting member. By providing the connection structure 330, more installation space can be provided for the connecting member, so that the liquid extraction joint 300 can be more conveniently detachably connected to the liquid separation box 100. Optionally, through holes can be provided on the connection structure 330, and the outer surface of the liquid separation box 100 has threaded holes corresponding to the through holes. The connecting member is a screw. By passing the screw through the through hole and screwing it into the threaded hole, the liquid extraction joint 300 can be detachably connected to the liquid separation box.

[0049] In some embodiments, in combination with Figure 1 and Figure 4 , a first groove 170 is recessed on the outer surface of the liquid separation box 100 and a first protrusion 140 correspondingly protrudes on the inner surface of the liquid separation box 100. It can be understood that the first groove 170 can be formed on the outer surface of the liquid separation box 100 through mechanical processing processes such as stamping, so that the first groove 170 can be formed without reducing the wall thickness of the liquid separation box 100, enabling the liquid separation box 100 to have sufficient structural strength; a first through hole 120 is provided in the first groove 170, and the connection structure 330 is detachably fixed to the first groove 170 of the liquid separation box 100 through a connecting member. By accommodating the connection structure 330 in the first groove 170, the connection structure 330 and a part of the tubular portion 310 can be accommodated inside the first groove 170, thereby reducing the volume of the liquid extraction joint 300 protruding outside the liquid separation box 100, and further reducing the possibility of interference between other parts or structures of the liquid delivery device 10 and the liquid extraction joint 300. Moreover, the part of the connection structure 330 that needs to be connected to the outer surface of the liquid separation box 100 forms a mating surface, and the mating surface has higher requirements for machining accuracy. If the entire outer surface of the liquid separation box 100 is used as the mating surface, it will increase the machining cost and difficulty. By providing the first groove 170 and detachably connecting the connection structure 330 to the inner surface of the first groove 170, the inner surface of the first groove 170 becomes the mating surface and the outer surface of the remaining part of the liquid separation box 100 is the non-mating surface, thereby reducing the machining cost and difficulty of the liquid separation box 100.

[0050] In some embodiments, as Figure 5 shown, a first guiding cylinder 23 is convexly provided on the inner surface of the liquid storage box 200, that is, the first guiding cylinder 230 is located in the liquid storage cavity. A second through hole 220 is formed in the first guiding cylinder 230, and the second end of the tubular portion 310 can extend into the first guiding cylinder 230. The first guiding cylinder 230 can provide guidance for the second end of the tubular portion 310, so that the second end of the tubular portion 310 can be more reliably connected to the second through hole 220.

[0051] In some embodiments, as Figure 6As shown, the third end of the suction pipe 700 is fixedly connected to the first guide cylinder 230. It can be understood that by providing the first guide cylinder 230 protruding from the inner surface of the liquid storage cavity 210, a larger space can be provided for the installation of the suction pipe 700, and the suction pipe 700 can be more reliably connected to the second through hole 220.

[0052] In some embodiments, in combination with Figure 6 and Figure 8 , the suction pipe 700 includes a base 710, a first boss 720, and a second tubular portion 730. The first boss 720 protrudes from the first surface of the base 710. The second tubular portion 730 protrudes from the outer surface of the side wall of the first boss 720. An included angle is formed between the extending direction of the first boss 720 and the extending direction of the second tubular portion 730. That is, the extending directions of the first boss 720 and the second tubular portion 730 are not parallel, thus forming a structure similar to an L shape. The second tubular portion 730 extends toward the bottom surface of the liquid storage cavity 210, and the second tubular portion 730 faces the bottom surface of the liquid storage cavity 210. At the same time, the first boss 720 is sleeved outside the first guide cylinder 230. It can be understood that by making the extending directions of the first boss 720 and the second tubular portion 730 different, the first boss 720 can be facilitated to be connected to the first guide cylinder 230 while the second tubular portion 730 can extend toward the bottom surface of the liquid storage cavity 210. Exemplarily, the first boss 720 can be a stepped structure.

[0053] There is also a suction channel 740 inside the suction pipe 700. The suction channel 740 penetrates through the base 710, the first boss 720, and the second tubular portion 730. The end of the second tubular portion 730 facing the bottom surface of the liquid storage cavity 210 forms a fourth end. A suction port 741 of the suction channel 740 is formed at the fourth end (the suction port 741 can have a certain distance from the bottom surface of the liquid storage cavity to facilitate liquid suction, and this distance is, for example, 2 mm). A third end is formed on the second surface of the base 710 opposite to the first surface, and a first communication port 742 is formed at the third end. The suction pipe 700 is connected to the second through hole 220 through the first communication port 742.

[0054] Among them, the second surface of the base 710 contacts the outer peripheral portion of the first guide cylinder 230 on the liquid storage box 200, so that the third end of the suction pipe 700 can stably abut against the inner surface of the liquid storage box 200. Next, in combination with Figure 7 and Figure 8, an exemplary description is given of the specific structure where the base 710 abuts against the inner surface of the liquid storage box 200. A first convex wall 232 is provided on the inner surface of the liquid storage box 200 around the outer periphery of the first guide cylinder 230. The suction pipe includes a second convex wall 711 and a third convex wall 712. The size and shape of the first convex wall 232 match those of the second convex wall, and the size and shape of the third convex wall 712 match those of the outer surface of the first guide cylinder 230. Thus, in the state where the suction pipe 700 is assembled with the liquid storage box 200, the first convex wall 232 is sleeved outside the second convex wall 711 and contacts the second surface, and the third convex wall 712 is sleeved outside the first guide cylinder 230. It can be understood that through the force between the second convex wall 711 and the first guide cylinder 230, and the force between the third convex wall 712 and the first convex wall 232, the swing of the suction pipe 700 relative to the liquid storage box 200 is further restricted, thereby making the connection between the suction pipe 700 and the first guide cylinder 230 more reliable. At the same time, the outer surface of the first guide cylinder 230, the second convex wall 711, the third convex wall 712, and the first convex wall 232 form a mating relationship, further improving the sealing performance between the suction pipe 700 and the first guide cylinder 230, and reducing the possibility of detergent leakage through the gap between the suction pipe 700 and the first guide cylinder 230.

[0055] Optionally, in combination with Figure 7 and Figure 8 , a gasket 750 is further provided between the second surface of the base 710 and the inner surface of the liquid storage box 200. The gasket 750 abuts against the second convex wall 711 and the third convex wall 712, and the gasket 750 and the first convex wall 232 surround and form an abutment with the second bottom surface, thereby further improving the sealing performance between the base 710 and the first guide cylinder 230.

[0056] Optionally, in combination with Figure 5 and Figure 8 , the second surface of the base 710 further has a base positioning hole 713. Figure 7 A guide cylinder positioning post 233 protrudes from the second bottom surface surrounded by the first convex wall 232 in Figure 6 . The guide cylinder positioning post 233 can extend into the base positioning hole 713. In the state where the guide cylinder positioning post 233 extends into the base positioning hole 713, as shown in Figure 7 , the second through hole 220 and the suction channel 740 in the first boss 720 are coaxial; at the same time, as shown in

[0057] Optionally, as shown in Figure 7As shown, in the first direction, a limiting protrusion 250 protrudes from the outer surface of the liquid storage box 200 on the side with the second through hole 220. The limiting protrusion 250 protrudes from the outer surface of the liquid storage box 200 in the first direction. During the process of the liquid storage box 200 sliding relative to the liquid distribution box 100 in the first direction, the limiting protrusion 250 can abut against the inner surface of the liquid distribution box 100, thereby limiting the movement stroke of the liquid storage box 200 and having a certain distance between the outer surface of the liquid storage box 200 and the inner surface of the liquid distribution box 100, so that the liquid storage box 200 does not completely occupy all the space of the liquid distribution cavity 110, thereby reducing the possibility that the liquid storage box 200 blocks Figure 1 the liquid inlet 150 in it. At the same time, in the first direction, the length of the limiting protrusion 250 extending out of the outer surface of the liquid storage box 200 is greater than the distance between the inner surface of the liquid distribution box 100 and the first liquid outlet 111, thereby reducing the possibility that the liquid storage box 200 blocks the first liquid outlet 111.

[0058] In some embodiments, as Figure 6 shown, the liquid storage box 200 further includes a one-way valve 240. An annular positioning platform 231 protrudes from the inner surface of the first guide cylinder 230. One end of the one-way valve 240 is accommodated in the first guide cylinder 230 and abuts against the bottom surface of the annular positioning platform 231. The other end of the one-way valve 240 is accommodated in the first boss 720, and the other end of the one-way valve 240 abuts against the inner surface of the first boss 720 or the inner surface of the second tubular portion 730. The one-way valve 240 is used to allow the detergent to only flow outwards from the liquid storage cavity 210. The inner surface of the first guide cylinder 230 and the inner surface of the first boss 720 surround the one-way valve 240 in the circumferential direction of the one-way valve 240 to perform circumferential positioning on the one-way valve 240. One of the inner surface of the first boss 720 and the inner surface of the second tubular portion 730, and the bottom surface of the annular positioning platform 231 are located on both sides of the one-way valve 240 in the axial direction of the one-way valve 240, thereby realizing axial positioning of the one-way valve 240.

[0059] In some embodiments, as Figure 10As shown, the liquid dispensing device 10 further includes a Venturi tube 800. The liquid separation box 100 further has a second liquid outlet 160. The Venturi tube 800 includes a Venturi tube main body 820 and a funnel-shaped structure 830. One end of the Venturi tube main body 820 is the water inlet, and the other end is the water outlet. In the direction from this end to the other end, the diameter of the Venturi tube main body 820 decreases to form a contraction section. A throat is formed at a position near the other end of the contraction section. A funnel-shaped structure 830 is connected near the throat of the contraction section. The end of the funnel-shaped structure 830 far from the Venturi tube main body 820 has the largest opening and forms a negative pressure suction port 810. When water flows from the water inlet to the water outlet, a negative pressure will be formed in the contraction section, so that a suction force can be formed at the negative pressure suction port 810. The second liquid outlet 160 is connected to the negative pressure suction port 810, so that the Venturi tube 800 can draw out the detergent in the liquid separation cavity 110 through the second liquid outlet 160 and mix it with water to form a multi-foam washing mixture, and can spray the washing mixture into the washing tub, thereby improving the washing efficiency. Among them, the detergent can include different types. By controlling the distance between the liquid inlet 150 and the second liquid outlet 160, the proportion of the detergent in the washing mixture can be controlled. The following is an exemplary description of the relevant structures of the liquid inlet 150 and the second liquid outlet 160.

[0060] Combined with Figure 2 and Figure 9 As shown, the number of the first through holes 120, the second through holes 220, the liquid inlets 150, the liquid extraction connectors 130, the liquid extraction tubes 500, the liquid return tubes 600 and the liquid extraction pipes 700 is two. The tubular parts 310 of the two liquid extraction connectors 300 respectively pass through the first through holes 120 and can be respectively connected to the two second through holes 220. The two liquid extraction tubes 500 respectively connect the two tubular parts 310 to the liquid extraction pump 400. The two liquid return tubes 600 respectively connect the liquid extraction pump 400 to the two liquid inlets 150. The two liquid extraction pipes 700 are respectively connected to the two second through holes 220. It can be understood that the two first through holes 120, the second through holes 220, the liquid inlets 150, the liquid extraction connectors 130, the liquid extraction tubes 500, the liquid return tubes 600 and the liquid extraction pipes 700 are respectively connected correspondingly to form two independent flow channels.

[0061] Meanwhile, a first chamber 211 and a second chamber 212 that are isolated from each other are formed within the liquid storage box 200. That is, the liquid storage chamber 210 includes the first chamber 211 and the second chamber 212 that are isolated from each other. Two second through holes 220 are respectively connected to the first chamber 211 and the second chamber 212. Meanwhile, the two liquid inlets 150 include a first liquid inlet 151 and a second liquid inlet 152. The first liquid inlet 151 is connected to the first chamber 211 through the above-mentioned one flow passage, and the second liquid inlet 152 is connected to the second chamber 212 through the above-mentioned other flow passage. As a result, the detergents in the first chamber 211 and the second chamber 212 can respectively flow through two independent flow passages and flow into the liquid separation chamber 110 from the first liquid inlet 151 and the second liquid inlet 152 respectively. Among them, the distance between the second liquid outlet 160 and the first liquid inlet 151 is less than the distance between the second liquid outlet 160 and the second liquid inlet 152. The first liquid inlet 151 is connected to the first chamber 211, and the second liquid inlet 152 is connected to the second chamber 212. The first chamber 211 is used to hold the main detergent, and the main function of the main detergent is to clean clothes. The second chamber 212 is used to hold the auxiliary detergent, and the function of the auxiliary detergent is to assist in cleaning clothes or achieve other functions. For example, the auxiliary detergent can be a special detergent for cleaning specific types of dirt. For example, the auxiliary detergent can be a fabric softener for making clothes softer. It can be understood that by connecting the first chamber 211 and the first liquid inlet 151, and the second chamber 212 and the second liquid inlet 152 through two independent liquid flow passages, the main detergent and the auxiliary detergent in the first chamber 211 and the second chamber 212 will not affect each other during the flow process. Meanwhile, by the distance between the first liquid inlet 151 and the second liquid outlet 160 being less than the distance between the second liquid inlet 152 and the second liquid outlet 160, the negative pressure suction port 810 can suck in more main detergent, so that the proportion of the main detergent in the washing mixed liquid output by the venturi tube 800 is increased, thereby improving the cleaning effect on clothes.

[0062] In some embodiments, a second guiding cylinder protrudes from the outer surface of the bottom surface of the liquid separation box 100. The second guiding cylinder has no bottom surface and only has a side surface. One end of the second guiding cylinder is connected to the bottom surface of the liquid separation box 100, and the connection part is the second liquid outlet 160 for guiding the washing mixed liquid out of the liquid separation box 100. The other end is connected to the negative pressure suction port of the venturi tube.

[0063] In some embodiments, such as Figure 10As shown, on the outer surface of the bottom surface of the liquid separation box 100, a second guiding cylinder 162 with a bottom surface and a side surface is convexly provided. In the thickness direction parallel to the bottom surface of the liquid separation box 100 and in the thickness direction perpendicular to the bottom surface of the liquid separation box 100, the second guiding cylinder 162 protrudes from the bottom surface of the liquid separation box 100. A second liquid outlet channel 161 is formed inside the second guiding cylinder 162. The second liquid outlet channel 161 is communicated with the liquid separation cavity 110, and one end of the second liquid outlet channel 161 communicated with the liquid separation cavity 110 forms a second liquid outlet 160. It can be understood that the second guiding cylinder 162 not only protrudes from the liquid separation box 100 in the thickness direction of the bottom surface of the liquid separation box 100, but also protrudes transversely from the bottom surface of the liquid separation box 100 in the direction perpendicular to this thickness direction, so that the second guiding cylinder 162 is not completely located directly below the liquid separation box 100, but is offset transversely in the direction away from the liquid separation box 100, so that the second guiding cylinder 162 and the venturi tube 800 can avoid other parts of the liquid delivery device 10 at the bottom of the liquid separation box 100. These other parts can be, for example, pipelines or wire harnesses.

[0064] The second guiding cylinder 162 is offset transversely in the direction away from the liquid separation box 100, and the second liquid outlet can only be opened in the overlapping area between the projection of the second guiding cylinder 162 on the bottom surface of the liquid separation box and the bottom surface of the liquid separation box 100. Therefore, the second liquid outlet 160 is not completely coaxial with the second guiding cylinder 162. In the thickness direction perpendicular to the bottom surface of the liquid separation box 100, compared with the second guiding cylinder 162, the second liquid outlet 160 is offset towards the side close to the liquid separation box 100. At the same time, due to the second guiding cylinder 162 being offset transversely in the direction away from the liquid separation box 100, a part of the second guiding cylinder does not take the bottom surface of the liquid separation box as the bottom surface, but has its own independent bottom surface. The second liquid outlet 160 can be opened on the side surface or the bottom surface of the second guiding cylinder 162. In order to obtain a larger second liquid outlet, the second liquid outlet 160 can be opened on the side surface and the bottom surface of the second guiding cylinder. In this way, the communication area between the second liquid outlet 160 and the liquid separation cavity 110 is increased, so that more detergent can flow out of the liquid separation cavity 110 through the second liquid outlet 160.

[0065] Moreover, in the thickness direction parallel to the bottom surface of the liquid separation box 100, the part of the funnel-shaped structure 830 close to the negative pressure suction port 810 and close to the liquid separation box 100 is located inside the second guiding cylinder 162 on the side away from the liquid separation box 100, so that the connection between the negative pressure suction port 810 and the second liquid outlet 160 is more reliable.

[0066] Optional, such as Figure 11As shown, an installation plate 165 also protrudes from the outer surface of the bottom surface of the liquid separation box 100. The installation plate 165 extends in a direction perpendicular to the thickness direction of the bottom surface of the liquid separation box 100. In the thickness direction parallel to the bottom surface, a part of the second guide cylinder 162 protrudes from the outer surface of the bottom surface of the liquid separation box 100, and another part protrudes from the outer surface of the installation plate 165. The second liquid outlet 160 is located in the liquid separation box 100, and the outer surface of the installation plate 165 forms at least a part of the bottom surface of the second guide cylinder 162.

[0067] In some embodiments, in combination with and Figure 11 , the Venturi tube 800 is fixedly connected to the liquid separation box 100. Specifically, on the outer surface of the liquid separation box 100, at least one installation cylinder 163 and at least one positioning column 164 protrude outward from the outer circumference of the second guide cylinder 162. The Venturi tube 800 further includes a second connection structure 821 located on the flank of the Venturi tube main body 820. The second connection structure 821 is provided with an installation hole 822 and a positioning hole 823. The positioning column 164 can pass through the positioning hole 823 and make the installation hole 822 and the installation cylinder 163 coaxial. The installation hole 822 can be detachably connected to the installation cylinder 163 through a connecting member. It can be understood that by providing the connection structure 821 on the side wall of the Venturi tube main body 820, the connecting member can have a larger operating space.

[0068] In some embodiments, such as Figure 12As shown, the liquid separation box 100 includes a liquid separation box body 181, a liquid separation box cover 182 and a top cover 183. The liquid separation box body 181 is fixedly connected to the liquid separation box cover 182, and the liquid separation box body 181 and the liquid separation box cover 182 enclose a liquid separation cavity 110. One side of the liquid separation box cover 182 facing away from the liquid separation cavity 110 has a fourth convex wall 1821, and the top cover 183 is fixedly connected to the fourth convex wall 1821. The fourth convex wall 1821 and the top cover 183 enclose a condensation cavity 184; and / or, the side of the top cover 183 facing the liquid separation cavity 110 is formed by the fourth convex wall 1821. The liquid separation box cover 182 is fixedly connected to the fourth convex wall 1821, and the fourth convex wall 1821 and the liquid separation box cover 182 enclose a condensation cavity 184; wherein, the liquid separation box cover 182 and the top cover 183 also enclose a pressure balance channel 186. The pressure balance channel 186 is connected to the washing cylinder through a pressure balance pipe 187. The pressure balance channel 186 is connected to the condensation cavity 184 and is used to condense the moisture in the hot and humid air entering the condensation cavity 184 through the pressure balance pipe 187. It should be noted that when water is injected into the washing cylinder, if the washing cylinder forms a closed cavity, the air pressure in the washing cylinder will continue to increase, ultimately resulting in difficult or even impossible water injection. It is necessary to connect the washing cylinder with the space where the liquid delivery device 10 is located through the pressure balance pipe 187, which will cause the humid air in the washing cylinder to enter the space where the liquid delivery device 10 is located. When the washing cylinder is in the drying state, the hot and humid air connects the washing cylinder with the space where the liquid delivery device 10 is located through the pressure balance pipe 187. In this state, the amount of water vapor in the air is greater. If the humid air directly enters the space where the liquid delivery device 10 is located, the water vapor in the humid air will form droplets in the entire space after condensation. If the droplets adhere to the outer surface of the liquid storage box 200, when the user pulls out the liquid storage box 200, these droplets will drip on the ground or the user's body, resulting in a reduced user experience.

[0069] By forming a condensation cavity 184 between the liquid separation box cover 182 and the top cover 183 and connecting the pressure balance pipe 187 to the condensation cavity 184 through the pressure balance channel 186, in the first direction (the first direction is as Figure 13On the side of the liquid separation box 100 away from the liquid storage box 200 as indicated by the arrow in the figure, the air pressure balance channel 186 is located on the side of the liquid separation box 100 away from the liquid storage box 200, and the fourth condensation chamber 184 is located on the side of the liquid separation box cover 182 close to the air pressure balance channel 186. It can be understood that the fourth convex wall 1821 is located on the side of the liquid separation box cover 182 close to the air pressure balance channel 186, and / or the top cover 183 is located on the side of the liquid separation box 182 close to the air pressure balance channel 186. That is, the condensation chamber 184 is located on the side away from the liquid storage box 200. At the same time, a second communication port 185 is opened inside the liquid separation box cover 182 located in the condensation chamber 184. The second communication port 185 connects the condensation chamber 184 and the liquid separation chamber 110. Thus, after the water vapor in the humid air condenses into droplets in the condensation chamber 184, the droplets fall into the liquid separation chamber 110 through the second communication port 185. And the condensation chamber 184 is located on the side away from the liquid storage box 200, so that the second communication port 185 is far away from the liquid storage box 200, and the condensed droplets fall into the liquid separation chamber 110 from a position far away from the liquid storage box 200. Furthermore, the possibility of the droplets adhering to the surface of the liquid storage box 200 is reduced, and the possibility of the droplets falling on the ground or on the user's body when the user takes out the liquid storage box 200 is reduced, improving the user experience.

[0070] In some embodiments, as Figure 13 shown, the fourth convex wall 1821 includes an outer peripheral convex wall 1822 and an inner convex wall 1823. The outer peripheral convex wall 1822 and the top cover 183 enclose to form the condensation chamber 184, and / or the outer peripheral convex wall 1822 and the liquid separation box cover 182 enclose to form the condensation chamber 184; the inner convex wall 1823 extends along a curve in the condensation chamber 184, and a condensation channel 1842 is formed in the condensation chamber 184. By making the inner convex wall 1823 extend along a curve, a condensation channel 1842 extending along a curve is formed, thereby increasing the surface area of the outer surface of the condensation channel 1842, enabling the condensation channel 1842 to contact the humid air entering the condensation chamber 184 more fully, and thus accelerating the condensation speed of the humid air; at the same time, heat exchange fins 1845 are convexly provided on the side walls of the outer peripheral convex wall 1822 and / or the inner convex wall 1823 adjacent to the condensation channel 1842, and the plurality of heat exchange fins 1845 are arranged at intervals along the extension direction of the condensation channel, thereby further increasing the surface area of the outer surface of the condensation channel 1842 and further accelerating the condensation speed of the humid air.

[0071] In some embodiments, as Figure 14 shown, there are multiple condensation channels 1842, and the distances between the projections of the multiple condensation channels 1842 on the first plane and the projection of the air pressure balance channel 186 on the first plane are different. The condensation channel 1842 with the smallest distance is the first condensation channel 1846. That is, the first condensation channel 1846 is the one closest to the air pressure balance channel 186 among all the condensation channels 1842. Here, the first plane is a plane with the thickness direction of the liquid separation box cover 182 as the normal line.

[0072] Meanwhile, the liquid separation box cover 182 also has a water inlet pipe 188. The water inlet pipe 188 is communicated with the first condensation channel 1846. The number of the second communication ports 185 on the part of the liquid separation box cover 182 located in the first condensation channel 1846 is greater than the number of the second communication ports 185 on the part of the liquid separation box cover 182 located in the second condensation channel 1847. The second condensation channel 1847 is the condensation channel 1842 other than the first condensation channel 1846 in the condensation channel 1842. It can be understood that the water inlet pipe 188 can introduce water into the first condensation channel 1846 and flow into the liquid separation cavity 110 through the second communication ports 185 located in the first condensation channel 1846, so that the detergent in the liquid separation cavity 110 is mixed with water. That is, the first condensation channel 1846 is not only used to achieve the condensation function, but also used to achieve the water inlet function. By arranging more second communication ports 185 in the first condensation channel 1846, the water flowing in from the water inlet pipe 188 can flow into the liquid separation cavity 110 from multiple different positions, so that the detergent can be more fully mixed with water.

[0073] Optionally, as Figure 14 shown, the heat exchange fins 1845 are arranged in the second condensation channel 1847 and are arranged at intervals along the extension of the second condensation channel 1847. While further improving the condensation capacity of the second condensation channel 1847, the heat exchange fins 1845 are not arranged in the first condensation channel 1846, so as to reduce the blocking effect of the heat exchange fins 1845 on the water flow flowing into the first condensation channel 1846 from the water inlet pipe 188 and reduce the flow resistance of the liquid flow in the first condensation channel 1846. Optionally, the projection of the second condensation channel 1847 on the bottom surface of the liquid separation cavity 110 is located in the first liquid outlet 111, so that the liquid droplets condensed in the second condensation channel 1847 can directly drip out of the liquid separation cavity 110 through the first liquid outlet 111 after dripping into the liquid separation cavity 110, thereby further reducing the possibility that the condensed water dripping into the liquid separation cavity 110 splashes and drops on the outer surface of the liquid storage box 200.

[0074] Optionally, as Figure 14 shown, the liquid separation box cover 182 also has a third liquid outlet 189. The third liquid outlet 189 is communicated with the first condensation channel 1846, and the third liquid outlet 189 can guide water to the sealing rubber cup of the washing machine door. The water entering the first condensation channel .....

[0075] In some embodiments, as Figure 14As shown, the outer surface of the side and / or bottom surface of the liquid separation box 100 has a pipeline fixing member 193, and the pipelines of the liquid delivery device 10 and the washing machine can be fixed to the outer surface of the liquid separation box 100 through the pipeline fixing member.

[0076] In some embodiments, as Figure 15 shown, the liquid storage box 200 includes a liquid storage box body 261 and a liquid storage box cover 262. A first chamber 211 and a second chamber 212 that are isolated from each other are formed inside the liquid storage box 200. Different types of detergents can be contained in the first chamber 211 and the second chamber 212 respectively. The liquid storage box body 261 also has a first liquid addition port 263 communicating with the first chamber 211 and a second liquid addition port 264 communicating with the second chamber 212. Users can supplement the corresponding types of detergents into the first chamber 211 and the second chamber 212 through the first liquid addition port 263 and the second liquid addition port 264 respectively.

[0077] One side of the liquid storage box cover 262 is rotatably connected to the liquid storage box body 261, and the rotation axis of the liquid storage box cover 262 is perpendicular to the first direction and perpendicular to the vertical direction. By rotating the liquid storage box cover 262 relative to the liquid storage box body 261, the liquid storage box cover 262 can cover or open the first liquid addition port 263 and the second liquid addition port 264. Moreover, the liquid storage box cover 262 can cover the first liquid addition port 263 and the second liquid addition port 264 simultaneously, that is, the liquid storage box cover 262 is a structure that can cover the first liquid addition port 263 and the second liquid addition port 264. Thus, by rotating the liquid storage box cover 262, the opening or closing of the first liquid addition port 263 and the second liquid addition port 264 can be controlled simultaneously, reducing the operation convenience of the liquid storage box cover 262.

[0078] At the same time, a chamfer 266 is provided on the opposite side of the side of the liquid storage box cover 262 connected to the liquid storage box body 261, thereby reducing the possibility of movement interference between the liquid storage box cover 262 and the liquid storage box body 261.

[0079] In some embodiments, as Figure 16 shown, the liquid storage box 200 further includes a magnetic float 251, and the liquid separation box 100 further includes a magnetic field intensity sensor. The magnetic float 251 is located in the liquid storage chamber 210, the magnetic field intensity sensor is fixed to the outer surface of the liquid separation box 100, the magnetic float 251 faces the magnetic field intensity sensor. The magnetic float 251 can float along with the liquid level of the detergent in the liquid storage chamber 210. The more the remaining amount of the detergent, the higher the liquid level of the detergent, the farther the magnetic float 251 is from the magnetic field intensity sensor. The less the remaining amount of the detergent, the lower the liquid level of the detergent, the closer the magnetic float 251 is to the magnetic field intensity sensor. That is, the remaining amount of the detergent has a negative correlation with the magnetic field intensity obtained by the magnetic field intensity sensor. The remaining amount of the detergent can be determined through the magnetic field intensity obtained by the magnetic field intensity sensor.

[0080] Meanwhile, the liquid storage box 200 further has a limiting column 253 and a pressing plate 252. The limiting column 253 extends along the height direction of the liquid storage cavity 210. One end of the limiting column 253 is fixed to the inner surface of the bottom surface of the liquid storage box 200, and the pressing plate 252 is fixed to the other end of the limiting column 253 opposite to this end. The magnetic float 251 is located between the inner surface of the bottom surface of the liquid storage box 200 and the pressing plate 252, and the magnetic float 251 is limited in the height direction of the liquid storage cavity 210 by this inner surface and the pressing plate 252.

[0081] Meanwhile, there are multiple limiting columns 253, and the multiple limiting columns 253 are arranged at intervals around the outside of the magnetic float 251, so as to perform more reliable circumferential positioning on the magnetic float 251 through the multiple limiting columns 253, so that the displacement of the magnetic float 251 in the direction perpendicular to the height direction is smaller, and further make the measurement of the remaining amount of the detergent more accurate.

[0082] In some embodiments, as Figure 17 shown, a second groove 242 is formed on the inner surface of the bottom surface of the liquid storage box 200. The second groove 242 includes a circular part 2421 and a rectangular part 2422. On this inner surface, the contour of the circular part 2421 is circular, and the contour of the rectangular part 2422 is rectangular. One end of the rectangular part 2422 is communicated with the circular part 2421, and one long side of the rectangular part 2422 is substantially tangent to the circular part 2421, so that the rectangular part 2422 and the circular part 2421 are smoothly transitioned to reduce the flow resistance between the rectangular part 2422 and the circular part 2421.

[0083] The suction port 741 is located in the rectangular part 2422 and close to the other end opposite to the end of the rectangular part 2422 communicated with the circular part 2421, that is, the end of the groove is used to accommodate the suction port 741 of the suction pipe 700, so that the suction port 741 is located at a lower position in the liquid storage cavity 210, which further facilitates the suction port 741 to suck the detergent more fully. At least part of the limiting column 253 and the magnetic float 251 are located in the circular part 2421. The circular part 2421 is used to accommodate the bottom of the limiting column 253 and the magnetic float 251, so that the magnetic float 251 can still measure the remaining amount of the detergent when the liquid level of the detergent is lower than the bottom surface of the liquid storage cavity 210 and is all accommodated in the second groove 242. Exemplarily, the end of the rectangular part 2422 where the suction port 741 is located can be the lower part in the second groove 242, so as to reduce the residue of the detergent in the liquid storage cavity.

[0084] The embodiment of the present invention further provides a washing device. The washing device can be, for example, a washing machine for washing clothes, or can also be a dishwasher for washing dishes. For the convenience of description, the washing device is described as a washing machine below.

[0086] Among them, the housing 20 includes a front panel 22 and a liquid separation box frame 23. The front panel 22 is provided with a liquid storage box opening 221. The liquid storage box 200 can be drawn out from the liquid separation box 100 through the liquid storage box opening 221, so as to facilitate operation when the detergent in the liquid storage box 200 needs to be replenished.

[0087] The front panel 22 is provided with a side wall recessed into the receiving cavity 21 around the liquid storage box opening 221. The side wall has a hook 24 protruding into the liquid storage box opening 221 and a connecting tab 25. The connecting tab 25 is provided with a second mounting hole 26. At the same time, the lower part of the liquid separation box frame 23 is provided with a first mounting hole 27, and the front surface of the liquid separation box 100 is provided with a third mounting hole 180. The hook 24 is used to limit the liquid separation box frame 23. By making the liquid separation box frame 23 abut against the liquid separation box frame 23, the preliminary positioning of the liquid separation box frame 23 can be realized. At the same time, the central axes of the first mounting hole 27, the second mounting hole 26, and the third mounting hole 180 are collinear. The connecting member sequentially passes through the first mounting hole 27, the second mounting hole 26, and the third mounting hole 180 to fixedly connect the liquid separation box frame 23, the front panel 22, and the liquid separation box 100. That is, by connecting, the liquid separation box frame 23, the front panel 22, and the liquid separation box 100 are fixedly connected at the same time, reducing the steps required for the assembly of the liquid separation box frame 23, the front panel 22, and the liquid separation box 100.

[0088] In some embodiments, such as Figures 1 to 17 Figure 20As shown, the liquid storage box 200 includes a liquid storage box body 261 and a handle plate 265. The handle plate 265 is fixed to the liquid storage box body 261. The lower part of the handle plate 265 protrudes from the liquid storage box body 261, and the handle plate 265 and the liquid distribution box 100 are located on both sides of the liquid distribution box frame 23. At the same time, a handle groove 2651 is provided on the surface of the lower part of the handle plate 265 facing away from the liquid distribution box frame 23, so as to facilitate the user to pull out the liquid storage box 200. A buckle 2652 is provided on the surface of the lower part of the handle plate 265 facing the liquid distribution box frame 23. The liquid distribution box frame 23 has a card slot 28. The card slot 28 and the first mounting hole 27 are distributed left and right. An avoidance hole 190 corresponding to the card slot 28 is provided on the front surface of the liquid distribution box 100, so as to reduce the possibility of interference between the buckle 2652 and the liquid distribution box 100. At the same time, the depth direction of the card slot 28 is parallel to the first direction. During the process of pushing the liquid storage box 200 into the liquid distribution box 100, the buckle 2652 can be engaged with the card slot 28, so as to reduce the possibility that the liquid storage box 200 accidentally disengages from the liquid distribution box 100 under the action of external force disturbance, which may be caused by the vibration of the washing machine. When the liquid storage box 200 is pulled out from the liquid distribution box 100, the buckle 2652 disengages from the card slot 28.
