Description

TECHNICAL FIELD

[0001] The present invention belongs to the technical field of washing equipment, and in particular relates to a dispensing device, and also relates to a washing machine equipped with the dispensing device.BACKGROUND

[0002] Detergent dispensing is a crucial component of washing machine operation. With the increasing automation of washing machines, automatic dispensing devices that can pre-store a certain amount of detergent are becoming increasingly popular. These devices typically include a liquid storage box containing detergent. During operation, a predetermined amount of detergent is drawn from the reservoir and dispensed into the washing machine's drum. This stored amount of detergent is sufficient for multiple washes, eliminating the need for users to refill detergent before each wash. This improves the automation level of the washing machine and enhances detergent dispensing accuracy.

[0003] However, the dispensing pump of existing dispensing device is generally installed within the housing, and the liquid storage box is connected to the extraction end of the dispensing pump via a docking valve. This solution easily causes the detergent in the liquid storage box to leak into the interior of the housing during the process of removing and placing the liquid storage box. To avoid this, some dispensing devices have a hose installed within the housing that connects the dispensing pump and the liquid storage box. The hose has a sufficient amount of space to allow the liquid storage box to be withdrawn, so that when the liquid storage box is withdrawn, it remains connected to the dispensing pump, thereby preventing the detergent in the liquid storage box from leaking. However, due to the long length of the hose and its inability to be fixed within the housing, it seriously hinders the withdrawal of the liquid storage box, affecting the user experience. At the same time, prolonged withdrawal and pulling will cause severe wear of the hose, shortening its service life.

[0004] Therefore, designing a dispensing device that can fix the hose in the housing to improve the guidance of the hose and reduce hose wear has become a technical problem that needs to be solved urgently by those skilled in the art.

[0005] In view of this, the present invention is proposed.SUMMARY

[0006] The objective of the present invention is to overcome the shortcomings of the existing technology and provide a dispensing device. By arranging a folding portion on the hose, the position and range of movement of the hose between the liquid storage box and the joint can be guided. At the same time, the guidance of the deformation position and deformation amplitude of the hose can be improved, thereby solving the problems of poor fixing effect and severe wear of the hose in the existing dispensing device.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: A dispensing device includes a housing, a side of which is provided with a connector for dispensing detergent, a liquid storage box that can be pulled out and placed from the side of the housing is provided inside the housing, the liquid storage box and the connector are connected via a dispensing pump and a hose. The hose is deformable for taking out the liquid storage box, and a folding portion is provided on the hose for guiding its deformation.

[0008] Furthermore, the folding portion includes a first guide tube and a second guide tube which are sleeved on the hose and hinged to each other, and the hinged end of the first guide tube and / or the second guide tube is provided with a guiding portion for guiding the bending of the hose.

[0009] Furthermore, the guiding portion is formed by the end portion of the first guide tube and / or the second guide tube expanding outward along an axial direction perpendicular to an axis of the hinge shaft.

[0010] Furthermore, the extension direction of the guiding portion is a curve that expands outward around the axis of the hinge shaft.

[0011] The curvature of the guiding portion gradually increases in a direction approaching the hinge axis.

[0012] Furthermore, the folding portion also includes a limiting portion arranged on the side of the first guide tube and the second guide tube, which is used to limit the line in the housing.

[0013] Furthermore, the limiting portion is provided at the top of the folding portion and includes a bending rib for fixing the line. The bending rib includes: a first bending rib, disposed on a first side of the folding portion and bent toward a second side of the folding portion; a second bending rib, disposed on the second side of the folding portion and is bent toward the first side of the folding portion.

[0014] The first bending rib and the second bending rib are disposed along an axis direction of first guide tube and a second guide tube and in a staggered manner.

[0015] Furthermore, the limiting portion also includes a first limiting groove and a second limiting groove arranged on the side of the guiding portion, with the groove opening facing away from the axis of the hinge shaft, and the bottom of the first limiting groove and the second limiting groove are set as a curved surface for the line to bend and wrap around.

[0016] Furthermore, the first guide tube and the second guide tube each include an accommodating groove for receiving the hose, and a limiting rib for limiting the hose in the accommodating groove.

[0017] The limiting rib is arranged at the notch of the accommodating groove.

[0018] Furthermore, the notches of the accommodating grooves of the first guide tube and the second guide tube are arranged opposite to each other; A plurality of limiting ribs are arranged at intervals at the notch of the accommodating groove on the side of the guiding portion away from the hinge shaft.

[0019] The present invention also provides a washing machine, comprising a washing machine body, on which the above-mentioned dispensing device is installed, and / or a base is detachably installed at the bottom of the washing machine body, on which the above-mentioned dispensing device is installed.

[0020] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: 1. The present invention provides a folding portion on the hose, which can guide the position and range of movement of the hose between the liquid storage box and the joint. At the same time, it can improve the guidance of the deformation position and deformation amplitude of the hose, thereby improving the controllability of the hose deformation, reducing the obstruction of the hose to the liquid storage box, and at the same time, reducing the wear of the hose caused by long-term pulling and drawing, thereby improving the user experience and increasing the service life of the hose. 2. The present invention sets the guiding portion to a shape with a curvature that gradually increases in the direction close to the hinge axis, so that the guiding portion can better adapt to the shape of the deformed position when the hose is bent, thereby further improving the guiding effect on the hose, preventing dead angles when the hose is bent, and improving the working stability of the dispensing device. 3. The present invention can fix the line in the housing by providing a limit portion at the top of the folding portion, which can reduce the influence of the line in the dispensing device on the pulling process of the liquid storage box and reduce the wear on the line.

[0021] At the same time, the present invention has a simple structure, significant effects, and is suitable for popularization and use.

[0029] As shown in FIGS. 1 and 2, in an embodiment of the present invention, a dispensing device is disclosed. The dispensing device can be installed on a washing machine or on an additional device of the washing machine, such as the washing machine base 2, as long as the dispensing device can dispense the detergent stored therein into the drum assembly 101 of the washing machine.

[0030] In this embodiment, the dispensing device includes a housing 5 and a liquid storage box 301. The liquid storage box 301 is removably disposed within the housing 5. Specifically, an opening is provided on one side of the housing 5, through which the liquid storage box 301 can be withdrawn and placed. A connector 203 for dispensing detergent into the drum assembly 101 of the washing machine is provided on the sidewall of the housing 5. The liquid storage box 301 is connected to the connector 203 via a dispensing pump 302. Thus, the dispensing pump 302 can pump the detergent pre-stored in the liquid storage box 301 and squeeze it into the drum assembly 101 of the washing machine through the connector 203.

[0031] In some embodiments, the dispensing pump 302 may be disposed on the liquid storage box 301. As shown in FIG. 2, the extraction end of the dispensing pump 302 is in communication with the liquid storage box 301, and the extrusion end of the dispensing pump 302 is in communication with the connector 203 on the housing 5 via a hose 204. The hose 204 has a sufficient amount of fluid to allow the liquid storage box 301 to be withdrawn. Thus, when the user withdraws the liquid storage box 301, the dispensing pump 302 is withdrawn along with the liquid storage box 301, and the liquid storage box 301 and the connector 203 remain in communication at all times.

[0032] In some embodiments, the dispensing pump 302 is mounted on the inner sidewall of the housing 5. As shown in FIG. 1, the extrusion end of the dispensing pump 302 is connected to the connector 203 from the inner end of the connector 203, and the extraction end of the dispensing pump 302 is connected to the liquid storage box 301 via a hose 204. The hose 204 is deformable for taking out the liquid storage box 301. Thus, when the user withdraws the liquid storage box 301, the liquid storage box 301 and the connector 203 remain connected.

[0033] In some embodiments, the dispensing pump 302 is disposed on the outer sidewall of the housing 5. The extraction end of the dispensing pump 302 is connected to the connector 203 from the outer end thereof. The extraction end of the dispensing pump 302 is connected to the drum assembly 101 of the washing machine. The inner end of the connector 203 is connected to the liquid storage box 301 via a hose 204. The hose is deformable for taking out the liquid storage box 301. Thus, when the user withdraws the liquid storage box 301, the liquid storage box 301 and the connector 203 remain connected.

[0034] In this embodiment, a hose 204 is provided between the dispensing pump 302 and the connector 203 / the liquid storage box 301 and the dispensing pump 302, so that the bottle opening 3015 of the liquid storage box 301 and the extraction end of the dispensing pump 302 can be prevented from being repeatedly separated and connected during the process of drawing the liquid storage box 301, so that the liquid storage box 301 and the dispensing pump 302 are always connected. Thereby preventing the detergent in the liquid storage box 301 from leaking into the interior of the housing 5, reducing detergent leakage, ensuring the cleanliness of the interior of the housing 5, and improving the user experience.

[0035] In this embodiment, the hose 204 may be a corrugated tube or a pressure-resistant tube.

When the bottle opening 3015 of the liquid storage box 301 is connected to the end of the dispensing pump 302 / hose 204 away from the dispensing pump 302, the bottle opening 3015 of the liquid storage box 301 is open. When the bottle opening 3015 of the liquid storage box 301 is separated from the end of the dispensing pump 302 / hose 204 away from the dispensing pump 302, the bottle opening 3015 of the liquid storage box 301 is closed. Therefore, after the liquid storage box 301 is withdrawn, the liquid storage box 301 can be removed separately, and then detergent can be added to the liquid storage box 301, making it more convenient for the user to add detergent.

[0037] Preferably, in this embodiment, the dispensing device further includes a drawer 202, and the drawer 202 is drawably arranged in the housing 5 through an opening on the housing 5, and the liquid storage box 301 is installed inside the drawer 202.

[0063] Specifically, the first guide tube and the second guide tube both include an accommodating groove 2081 and a limiting rib 2082. The accommodating groove 2081 is used to receive the hose 204. The limiting rib 2082 is used to limit the hose 204 in the accommodating groove 2081. The limiting rib 2082 is arranged at the notch of the accommodating groove 2081.

[0064] In this embodiment, the notches of the accommodating grooves 2081 of the first guide tube and the second guide tube are arranged relative to each other, the hose 204 is arranged in the accommodating groove 2081, and a plurality of limiting ribs 2082 are arranged at intervals at the notches of the accommodating groove 2081 to limit the hose 204 in the accommodating groove 2081.

[0065] The limiting ribs 2082 extend from the notch of the accommodating groove 2081 in a direction perpendicular to the direction of the accommodating groove 2081 toward the inside of the notch. The limiting ribs 2082 can be provided on one side of the notch or on both sides of the notch. Preferably, the limiting ribs 2082 are provided on both sides of the notch, and the limiting ribs 2082 provided on both sides of the notch are arranged in a staggered manner.

[0066] In some embodiments, after the folding portion 208 is installed, the hose 204 can move axially relative to the folding portion 208, thereby ensuring relative rotation of the first guide tube and the second guide tube. Preferably, the hose 204 is fixedly connected to one of the first guide tube and the second guide tube, and axially movable with the other of the first guide tube and the second guide tube, thereby ensuring the stability of the relative position between the folding portion 208 and the hose 204 and improving the reliability of the operation of the folding portion 208.

[0067] In other embodiments, the first guide tube and the second guide tube of the folding portion 208 are both axially limitedly connected to the hose 204, that is, the limiting rib 2082 clamps the hose 204 in the accommodating groove 2081, and the hose 204 in the folding portion 208 is at least partially configured to be retractable, or, the hose 204 in the folding portion 208 is provided with a margin for relative rotation of the first guide tube and the second guide tube, as long as it can be ensured that the folding portion 208 can be folded smoothly.

[0068] Preferably, in this embodiment, the hinged end of the first guide tube and / or the second guide tube is provided with a guiding portion 2083 for guiding the bending of the hose 204.

[0069] The guiding portion 2083 is formed by the end of the first guide tube and / or the second guide tube extending outwardly in a direction perpendicular to the axis of the hinge axis. In this embodiment, the provision of the guiding portion 2083 can, on the one hand, prevent the formation of a dead angle at the bend of the hose 204 when the folding portion 208 is bent, and on the other hand, the provision of the guiding portion 2083 can accommodate the excess of the hose 204 for bending deformation, thereby allowing the folding portion 208 to be smoothly deployed and bent.

[0070] Preferably, in this embodiment, the guiding portion 2083 extends in a curve that expands outward about the axis of the hinge shaft, with the curvature of the guiding portion 2083 gradually increasing as it approaches the hinge shaft. This allows the guiding portion 2083 to better adapt to the shape of the hose 204 when it is bent, further enhancing its guiding effect on the hose 204, preventing blind spots when the hose 204 is bent, and improving the operational stability of the dispensing device.

[0071] In this embodiment, the limiting rib 2082 is arranged on the side of the first guide tube and the second guide tube away from the guiding portion 2083, that is, the limiting rib 2082 is only arranged at the notch of the accommodating groove 2081 and does not extend to the corresponding position of the guiding portion 2083.

[0072] In some embodiments, a guiding portion 2083 is provided on both the first guide tube and the second guide tube, and a limiting rib 2082 is provided at the junction of the accommodating groove 2081 of the first guide tube and the second guide tube and the guiding portion 2083. When the folding portion 208 is bent, the limiting rib 2082 at the junction of the accommodating groove 2081 of the first guide tube and the second guide tube and the guiding portion 2083 contacts the hose 204, causing the portion of the hose 204 corresponding to the guiding portion 2083 to bend.

[0073] In other embodiments, the hinged end of the first guide tube is provided with a guiding portion 2083, and the hinged end of the second guide tube is not provided with a guiding portion 2083. A limiting rib 2082 is provided on the first guide tube at the junction of the accommodating groove 2081 and the guiding portion 2083, and a limiting rib 2082 is provided at the hinged end of the second guide tube, so that the excess on the hose 204 is set in the guiding portion 2083 of the first guide tube.

[0074] In this embodiment, the ends of the guiding portions 2083 on the first guide tube and the second guide tube are spaced apart to allow the folding portion 208 to be smoothly unfolded.

[0075] In this embodiment, the bottom of the accommodating groove 2081 can be in any shape, such as a flat surface or an arc shape. Preferably, the bottom of the accommodating groove 2081 is configured to be in an arc shape that fits the outer wall of the hose 204, thereby improving the tightness of the folding portion 208 and the hose 204.

[0076] In some embodiments, there is one hose 204. In this case, the first guide tube and the second guide tube each have an accommodating groove 2081.

[0077] In other embodiments, the hose 204 is provided in multiple pieces, for example, the hose 204 includes a first pipeline 2041 and a second pipeline 2042.

[0094] As shown in FIGS. 1 to 20, in an embodiment of the present invention, a dispensing device is disclosed. The dispensing device can be installed on a washing machine or on an additional device of the washing machine, such as the washing machine base 2, as long as the dispensing device can dispense the detergent stored therein into the drum assembly 101 of the washing machine.

[0095] In this embodiment, the dispensing device includes a liquid storage box 301, a cavity for accommodating the liquid storage box 301, and a dispensing pump 302. The liquid storage box 301 is detachably installed in the cavity. When the liquid storage box 301 is installed in the cavity, the liquid storage box 301 is connected to the dispensing pump 302. When the liquid storage box 301 is taken out, the liquid storage box 301 is disconnected from the dispensing pump 302.

[0096] Specifically, as shown in FIGS. 13 and 15, the liquid storage box 301 is configured in the form of an ink cartridge. An on-off valve is provided at the bottle opening 3015 of the liquid storage box 301. A dispensing pipeline 212 is provided in the cavity. One end of the dispensing pipeline 212 is connected to the extraction end of the dispensing pump 302, and the other end of the dispensing pipeline 212 at least partially extends into the cavity. When the liquid storage box 301 is inserted into the cavity, the bottle opening 3015 of the liquid storage box 301 corresponds to the end of the dispensing pipeline 212. During the insertion process, the end of the dispensing pipeline 212 presses against the valve core of the on-off valve, opening it and achieving communication between the liquid storage box 301 and the dispensing pump 302.

[0097] In this embodiment, the dispensing device may have an independent housing 5, and a cavity is defined by the housing 5. The dispensing device may also not have an independent housing 5, and the cavity may be directly integrated into the washing machine body 1 or the washing machine base 2.

[0098] As shown in FIG. 15, in this embodiment, a connecting groove 4 is further provided inside the cavity, and the dispensing pipeline 212 at least partially extends into the connecting groove 4. The connecting groove 4 is used to accommodate the bottle opening 3015 of the liquid storage box 301 when the liquid storage box 301 is loaded, thereby guiding and positioning the loading of the liquid storage box 301. At the same time, the connecting groove 4 can also collect the detergent leaked from the bottle opening 3015 of the liquid storage box 301 when the bottle opening 3015 of the liquid storage box 301 is connected to the dispensing pipeline 212, thereby preventing the detergent from leaking into the cavity and making the leaked detergent easier to clean.

[0099] The opening of the connecting groove 4 is oriented parallel to the direction in which the liquid storage box 301 is inserted, i.e., the connecting groove 4 is disposed toward the insertion opening of the liquid storage box 301. The internal shape of the connecting groove 4 matches the shape of the bottle opening 3015 of the liquid storage box 301. The end of the dispensing pipeline 212 is disposed within the connecting groove 4. When the liquid storage box 301 is inserted, the outer wall of the bottle opening 3015 abuts against the inner wall of the connecting groove 4, and the end of the dispensing pipeline 212 is inserted into the bottle opening 3015, opening the on-off valve.

[0100] Preferably, in this embodiment, the connecting groove 4 is detachably mounted on the inner wall of the cavity. By arranging the connecting groove 4 to be detachably mounted on the inner wall of the cavity, it is convenient for the user to remove the connecting groove 4 and clean it. Specifically, the user can remove the connecting groove 4 and rinse it with water if it is not too dirty. If it is quite dirty, the user can soak it in water for more than ten minutes, then gently brush the connecting groove 4 with a small brush, and then rinse it with water. This can prevent the dispensing pipeline 212 or the bottle opening 3015 from being blocked, thereby improving the user experience.

[0101] As shown in FIG. 17, in this embodiment, the connecting groove 4 is detachably mounted on the inner wall of the cavity via an elastic buckle 6. Specifically, the connecting groove 4 includes a connecting groove base 402 and a connecting groove body 401, which are interconnected / integrally formed. The connecting groove base 402 is provided with a snap-fit mounting port 406. The elastic buckle 6 engages within the snap-fit mounting port 406 on the connecting groove base 402, causing the connecting groove base 402 to fit tightly against the inner wall of the cavity. The connecting groove body 401 is disposed on the side of the connecting groove base 402 away from the inner wall, with the slot of the connecting groove body 401 oriented perpendicular to the inner wall of the cavity.

[0102] As shown in FIGS. 15 to 17, in this embodiment, the end of the dispensing pipeline 212 extends upward within the cavity. The dispensing pipeline 212 is fixed to the bottom wall of the cavity via screws, bolts, or other connectors. The connecting groove 4 is sleeved over the dispensing pipeline 212, and the end of the dispensing pipeline 212 at least partially extends into the connecting groove body 401. The liquid storage box 301 is installed in the cavity from top to bottom, with the bottle opening 3015 of the liquid storage box 301 facing downward. During installation, the bottle opening 3015 of the liquid storage box 301 is embedded in the connecting groove body 401, and the dispensing pipeline 212 is connected to the liquid storage box 301 via an on-off valve within the bottle opening 3015.

[0103] As shown in FIG. 18, in this embodiment, a through-hole 404 is provided on the bottom of the connecting groove body 401, and the inner diameter of the through-hole 404 is adapted to the diameter of the dispensing pipeline 212. The connecting groove 4 is sleeved on the end of the dispensing pipeline 212, and the outer wall of the dispensing pipeline 212 is fitted with the inner wall of the through-hole 404.

[0104] Preferably, in this embodiment, the through-hole 404 extends upward / downward from the bottom of the connecting groove body 401, so that the through-hole 404 forms a sleeve shape, which makes it easier to seal between the through-hole 404 and the dispensing pipeline 212.

[0105] Preferably, in this embodiment, a boss for fixing is provided at the bottom of the dispensing pipeline 212, the bottom of the boss is fixedly connected to the bottom wall of the cavity by screws / bolts, the top of the boss protrudes from the circumference of the dispensing pipeline 212, and the bottom of the through-port 404 abuts against the top of the boss.

[0106] Preferably, in this embodiment, a sealing ring is provided between the inner wall of the through-hole 404 and the outer wall of the dispensing pipeline 212.

[0107] Further preferably, the sealing ring is sleeved on the dispensing pipeline 212 and has an interference fit with the inner wall of the through-hole 404. Specifically, a groove is formed on the outer wall of the dispensing pipeline 212, and the sealing ring is embedded in the groove. The sealing ring at least partially protrudes from the outer wall of the dispensing pipeline 212. When the connecting groove 4 is installed, the sealing ring elastically abuts against the through-hole 404, further improving the sealing performance and preventing detergent leakage from flowing out of the connecting groove 4 through the gap between the inner wall of the through-hole 404 and the outer wall of the dispensing pipeline 212.

[0108] As shown in FIG. 17, in this embodiment, the elastic buckle 6 includes an elastic portion 601 and a buckle protrusion 602. The elastic wall is generally U-shaped, with one end connected to the circumference of the dispensing pipeline 212, and the other end extending toward the inner wall of the cavity before bending and extending away from the inner wall of the cavity. The buckle protrusion 602 is provided on the side of the elastic portion 601 away from the dispensing pipeline 212. The side away from the elastic portion 601 is configured as an inclined surface that tilts toward the side away from the elastic portion 601 along the insertion direction of the connecting groove 4, while the side close to the inner wall of the cavity is configured as a flat surface parallel to the inner wall of the cavity.

[0109] Thus, when the connecting groove 4 is sleeved on the dispensing pipeline 212 along the installation direction, the bottom of the connecting groove 4 presses against the inclined surface of the buckle protrusion 602, causing the elastic portion 601 to produce elastic deformation in the direction of approaching the dispensing pipeline 212, so that the connecting groove 4 can continue to move downward. When the bottom of the connecting groove 4 is in contact with the inner wall of the cavity, the bottom surface of the buckle protrusion 602 is flush with the bottom surface of the snap-fit mounting port 406, the elastic wall rebounds, and the buckle protrusion 602 enters the snap-fit mounting port 406 on the connecting groove base 402, and the connecting groove base 402 is limited between the buckle protrusion 602 and the inner wall of the cavity.

[0110] When the user wants to remove the connecting groove 4, the user only needs to press the elastic portion 601 and / or the buckle protrusion 602 toward the direction close to the dispensing pipeline 212 to separate the buckle protrusion 602 from the snap-fit mounting port 406.

[0111] In this embodiment, a plurality of dispensing pipelines 212 for connecting to a plurality of liquid storage boxes 301 are provided on the inner wall of the cavity, and the connecting groove base 402 is sleeved on at least two dispensing pipelines 212 and is provided with a connecting groove body 401 corresponding to each dispensing pipeline 212 one by one.

[0112] In some embodiments, the connecting groove 4 has two connecting groove bodies 401, and the connecting groove 4 is simultaneously sleeved on two dispensing pipelines 212. The two connecting groove bodies 401 are respectively sleeved on one dispensing pipeline 212, and an elastic buckle 6 is respectively provided on the two dispensing pipelines 212. After the connecting groove 4 is installed, it is fixed by the two elastic buckles 6 to ensure the stability of the installation of the connecting groove 4.

[0113] In other embodiments, the connecting groove 4 has two or more connecting groove bodies 401, and the connecting groove 4 is simultaneously mounted on multiple dispensing pipelines 212. The number of dispensing pipelines 212 corresponds to the number of connecting grooves 4, and each connecting groove body 401 is mounted on a dispensing pipeline 212. In this embodiment, at least two dispensing pipelines 212 are provided with elastic buckles 6, that is, the connecting groove 4 is mounted on the inner wall of the cavity via at least two elastic buckles 6, thereby ensuring the stability of the installation effect of the connecting groove 4.

[0114] Preferably, in this embodiment, when the connecting groove 4 is correspondingly mounted on two or more dispensing pipelines 212, the dispensing pipelines 212 are arranged side by side, that is, arranged on the same straight line. In this case, the elastic buckles 6 are installed on at least the dispensing pipelines 212 at both ends. Further preferably, the elastic buckles 6 on the dispensing pipelines 212 at the left and right ends face opposite directions, thereby further ensuring the stability of the installation effect of the connecting groove 4.

[0115] In this embodiment, a leakage collection groove 405 is further provided on the connecting groove base 402. The leakage collection groove 405 is communicated with the connecting groove body 401 and is used to collect leaked detergent to facilitate further cleaning by the user.

[0116] Specifically, the leakage collection groove 405 is provided on one side of the connecting groove body 401. The opening of the leakage collection groove 405 is lower than the bottom of the connecting groove body 401, or alternatively, the opening of the leakage collection groove 405 is flush with the bottom of the connecting groove body 401. A flow hole 403 is provided at the bottom of the side wall of the connecting groove body 401 near the leakage collection groove 405. During the process of removing or loading the liquid storage box 301, leaked detergent flows into the connecting groove body 401 and then flows along the bottom of the connecting groove body 401 into the leakage collection groove 405.

[0117] Preferably, in this embodiment, the notch of the connecting groove body 401 is set upward, and the bottom of the connecting groove body 401 is set as an inclined surface inclined downward toward the leakage collection groove 405, so that the leaked detergent can be accelerated to flow into the leakage collection groove 405, preventing the leaked detergent from being retained in the connecting groove body 401.

[0118] Further preferably, in this embodiment, at least the groove wall of the leakage liquid collection groove 405 close to the connecting groove body 401 is configured as an inclined surface inclined from top to bottom toward the leakage liquid collection groove 405 side.

[0119] As shown in FIGS. 17 and 18, in this embodiment, the leakage collection groove 405 is arranged on the side of the connecting groove 4 away from the elastic buckle 6, that is, the leakage collection groove 405 and the elastic buckle 6 are respectively arranged on both sides of the dispensing pipeline 212, thereby making the structural layout of the connecting groove 4 more reasonable.

[0120] In this embodiment, when a plurality of connecting groove bodies 401 are provided on a connecting groove 4, each connecting groove body 401 may be connected to a corresponding liquid leakage collection groove 405, or multiple connecting groove bodies 401 may be connected to a liquid leakage collection groove 405 at the same time.

[0121] Preferably, in this embodiment, each connecting groove body 401 is connected to a corresponding liquid leakage collection groove 405, or a plurality of connecting groove bodies 401 corresponding to the liquid storage box 301 storing the same type of detergent are connected to the same liquid leakage collection groove 405, thereby avoiding the mixing of different types of leaked detergents, allowing users to reuse the detergent collected in the leakage collection groove 405, and avoiding waste of resources.

[0122] In this embodiment, the dispensing device also includes an alarm device, which can be the washing machine's own alarm device or a separate alarm device provided on the dispensing device. A leakage detection device is provided in the leakage collection groove 405. The leakage detection device is communicatively connected to the alarm device and is configured to trigger an alarm when the liquid level in the leakage collection groove 405 reaches a preset value. The provision of the leakage detection device and the alarm device can remind the user to promptly clean up any leaked detergent collected in the connecting tank 4, preventing excessive detergent from accumulating in the leakage collection groove 405 or even leaking into the cavity, further enhancing the user experience.

[0123] In this embodiment, the liquid leakage detection device can be a micro switch, a liquid level sensor, etc.

[0124] In some embodiments, the liquid leakage detection device includes a button, a first pressing plate and a second pressing plate. When there is no leakage in the leakage collection groove 405, the button is pressed down, and the first pressing plate and the second pressing plate are fitted together; as the leakage level in the leakage collection groove 405 rises, the button gradually rises. When the button rises to a certain height, the first pressing plate and the second pressing plate are disconnected, and at this time, the alarm device starts to alarm.

[0125] In this embodiment, the dispensing device includes a housing 5 and a drawer 202. The drawer 202 is retractable and arranged in the housing 5.

When the external dispensing module is in operation, any one or more dispensing pumps 302 are controlled to operate, and the detergent in the corresponding liquid storage box 301 is dispensed into the flushing channel of the distribution box 303, and then flushed and diluted by the incoming water flow and flows into the barrel assembly 101.Embodiment 7

[0221] This embodiment discloses a control method for a washing machine, which specifically includes the following steps: S1: Power on; S2: Obtaining information about clothes to be washed; S3: Selecting detergent according to the information of the clothes to be washed; S3.1: If the selected detergent is stored in the built-in liquid storage box, controlling the built-in dispensing module in the washing machine body 1 to dispense the detergent; S3.2: If the selected detergent is stored in the liquid storage box 301, controlling the external dispensing module to dispense the detergent.

[0222] In this embodiment, a database is established in the system of the washing machine, and when the user fills the detergent into the built-in liquid storage box, the detergent information of the detergent is entered into the system.

[0223] Specifically, the washing machine is provided with an information entry port. When the user needs to add detergent into the built-in dispensing module, the user can align the packaging bottle / packaging bag of the detergent to be filled into the built-in dispensing module with the information entry port. The information entry port on the washing machine scans the QR code, barcode or other identification code on the detergent packaging bottle / packaging bag to obtain the type of detergent and the electronic instruction manual, and obtain the detergent information from them; the user can also enter the detergent information manually.

[0224] In some embodiments, an external dispensing module is installed on the washing machine, and detergent information stored in the external dispensing module's liquid storage box 301 is entered into the washing machine's system database via an information entry port on the washing machine. When the washing machine dispenses detergent, it directly matches the optimal detergent in the washing machine's database based on the laundry information, and controls the internal dispensing module or the external dispensing module to dispense the detergent.

[0225] In some embodiments, the external dispensing module has a separate database. When the external dispensing module is connected to the washing machine, the detergent information stored in the external dispensing module's liquid storage box 301 is entered into the external dispensing module's database through the washing machine's information entry port for separate storage. When the washing machine dispenses detergent, the washing machine's system simultaneously retrieves the detergent information from the external dispensing module's database, matches the optimal detergent between the washing machine's database and the external dispensing module's database based on the laundry information, and controls either the internal dispensing module or the external dispensing module to dispense the detergent.

[0226] In this embodiment, a separate database is established for the external dispensing module, so that when the external dispensing module is removed, there is no need to modify the detergent information written in the database of the washing machine. At the same time, when the external dispensing module that has already stored detergent is installed on the washing machine, there is no need to re-enter the detergent information stored in the external dispensing module, which can make it easier to disassemble and assemble the external dispensing module and ensure the accuracy of the detergent information read by the washing machine system.

[0227] Preferably, in this embodiment, the external dispensing module is also provided with a WIFI unit, and the user can connect the external dispensing module with a mobile terminal such as a mobile phone through the WIFI unit to obtain the detergent information in the external dispensing module and push it to the washing machine end, or the washing machine end can directly connect with the external dispensing module through the WIFI unit to obtain the detergent information stored therein.

[0228] In this embodiment, the external dispensing module can also write the detergent information stored therein through a mobile terminal connected to its WIFI module. Specifically, when a user needs to add detergent to the external dispensing module, the user can use a mobile phone to scan the QR code, barcode, or other identification code on the bottle / bag of detergent to be filled into the built-in dispensing module to obtain the type of detergent and the electronic manual, obtain the detergent information from it, and write the obtained detergent information into the database of the external dispensing module through the WIFI module. After the external dispensing module is installed on the washing machine, when the washing machine needs to add detergent, the washing machine system can synchronously retrieve the detergent information stored in the external dispensing module. As a result, the external dispensing module can be loaded with detergent and the corresponding detergent information can be entered without being connected to the washing machine, thereby improving the user experience.

[0229] Preferably, in this embodiment, the information about the laundry to be washed at least includes the color of the laundry to be washed.

[0230] In this embodiment, the built-in liquid storage box of the built-in dispensing module stores a first detergent for washing light-colored clothes, and the liquid storage box 301 of the external dispensing module stores a second detergent for washing dark-colored clothes.

[0231] After the washing machine is turned on, the drum assembly 101 runs at a preset speed to shake out the clothes to be washed.

[0232] The internal image of the drum assembly 101 is obtained, and the built-in dispensing module and / or the external dispensing module are selected for delivery according to the internal image of the drum assembly 101.Embodiment 8

[0233] In this embodiment, a method for controlling a washing machine is disclosed, which specifically includes the following steps: S1.0: Getting the inlet water temperature when water is entering; S2.0: If the temperature of the inlet water flow is greater than or equal to the preset temperature, the inlet pipe is connected to the built-in dosing module; S3.0: If the temperature of the inlet water flow is lower than the preset temperature, the water inlet pipe is connected to the external dispensing module in the base 2.

[0234] In this embodiment, detergents are stored separately according to their optimal washing temperatures. Specifically, detergents with higher optimal washing temperatures are stored in the built-in liquid storage box of the dispensing device, while detergents with lower optimal washing temperatures are stored in the liquid storage box 301 of the external dispensing module. Directing the higher-temperature inlet water flow directly from the washing machine's first water inlet 102 and the built-in dispensing module into the drum assembly 101 can reduce heat loss from the inlet water flow and improve washing performance. Furthermore, it can prevent the higher-temperature inlet water flow from damaging the piping of the external dispensing module, thereby increasing the service life of the external dispensing module.
