Description

[Technical Field]

[0001] The present invention belongs to the technical field of laundry equipment, and in particular to a discharge device and to a washing machine to which said discharge device is attached. [Background technology]

[0002] Detergent dispensing is an important component of washing machine operation. As washing machines become more automated, automatic dispensers that can store a certain amount of detergent in advance are gradually becoming more common. Automatic dispensers generally include a liquid storage box that stores detergent. During operation of the washing machine, a certain amount of detergent can be drawn from the liquid storage box and dispensed into the drum. The amount of detergent stored in the liquid storage box allows the washing machine to perform multiple washes, eliminating the need for users to add detergent before each wash. This improves the automation level of the washing machine while also improving the accuracy of detergent dispensing.

[0003] However, in conventional dispensing devices, the dispensing pump is typically mounted within a housing, and the liquid storage box is connected to the suction end of the dispensing pump via a connecting valve. This method is prone to the detergent in the liquid storage box leaking into the housing when the liquid storage box is inserted or removed. To avoid this, some dispensing devices have a hose inside the housing connecting the dispensing pump and the liquid storage box. The hose has an extra length to allow the liquid storage box to be pulled out, so that it remains in communication with the dispensing pump when the liquid storage box is pulled out, thereby preventing detergent from leaking from the liquid storage box. However, the hose is long and cannot be fixed within the housing, which seriously hinders the liquid storage box from being pulled out, affecting the user experience. Furthermore, prolonged pulling out of the hose causes serious wear on the hose, affecting its service life.

[0004] Therefore, designing a discharge device that can fix the hose in the housing, thereby improving the guiding of the hose and reducing wear on the hose, is a technical challenge that must be solved as soon as possible by those skilled in the art.

[0005] In view of this, the present invention has been presented. Summary of the Invention [Problem to be solved by the invention]

[0006] The technical problem that the present invention aims to solve is to overcome the shortcomings of the prior art and provide a discharge device that can guide the position and movable range of the hose between the liquid storage box and the joint by installing a folding arm on the hose, while at the same time improving the guiding ability for the deformation position and deformation width of the hose, thereby solving the problems of the prior art that the hose is not fixed effectively in the discharge device and is subject to serious wear. [Means for solving the problem]

Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention according to specific circumstances. [Example]

[0033] 1 and 2, an embodiment of the present invention introduces a discharging device. The discharging device may be mounted on a washing machine or on ancillary equipment of the washing machine. For example, the washing machine base 2 only needs to ensure that the discharging device can discharge the detergent stored in the discharging device into the drum assembly 101 of the washing machine.

[0034] In this embodiment, the discharging device includes a housing 5 and a liquid storage box 301, and the liquid storage box 301 is removably installed in the housing 5. Specifically, an opening is provided on one side of the housing 5, and the liquid storage box 301 can be removed and inserted through the opening. A coupling 203 for delivering detergent into the drum assembly 101 of the washing machine is provided on the side wall of the housing 5, and the liquid storage box 301 is connected to the coupling 203 via a discharging pump 302. As a result, the discharging pump 302 can extract the detergent previously stored in the liquid storage box 301 and pump it into the drum assembly 101 of the washing machine via the coupling 203.

[0035] 2, the discharge pump 302 has a suction end connected to the liquid storage box 301, and a discharge end connected to a fitting 203 on the housing 5 via a hose 204. The hose 204 has an excess length to allow the liquid storage box 301 to be pulled out. Thus, when a user pulls out the liquid storage box 301, the discharge pump 302 is pulled out together with the liquid storage box 301, and communication between the liquid storage box 301 and the fitting 203 is always maintained.

[0036] 1, the discharge pump 302 has a discharge end connected to the joint 203 from the inner end thereof, and a suction end connected to the liquid storage box 31 via the hose 204, and the hose 204 has an excess length for allowing the liquid storage box 301 to be pulled out. This allows the liquid storage box 301 and the joint 203 to always communicate with each other when the user pulls out the liquid storage box 301.

[0037] In some possible embodiments, the discharge pump 302 may also be mounted on the outer wall of the housing 5. The suction end of the discharge pump 302 is connected to the outer end of the joint 203, the suction end of the discharge pump 302 is connected to the drum assembly 101 of the washing machine, and the inner end of the joint 203 is connected to the liquid storage box 301 via the hose 204, and the hose 204 has an excess length to allow the liquid storage box 301 to be pulled out. Thus, when a user pulls out the liquid storage box 301, communication is always maintained between the liquid storage box 301 and the joint 203.

[0038] In this embodiment, the discharge pump 302 and the joint 203, and the liquid storage box 301 and the discharge pump 302 are connected via hoses, thereby preventing the bottle-neck opening 3015 of the liquid storage box 301 and the suction end of the discharge pump 302 from repeatedly separating and joining when the liquid storage box 301 is pulled out, and ensuring that the liquid storage box 301 and the discharge pump 302 are always connected to each other. This prevents the detergent in the liquid storage box 301 from leaking into the housing 5, reduces detergent leakage, ensures the cleanliness of the inside of the housing 5, and improves the user experience.

[0039] In this embodiment, the hose 204 may be a corrugated pipe or a pressure-resistant pipe.

[0040] In this embodiment, there is a detachable connection between the bottle-mouth-shaped opening 3015 of the liquid storage box 301 and the suction end of the discharge pump 302, or there is a detachable connection between the bottle-mouth-shaped opening 3015 of the liquid storage box 301 and an end of the hose 204 that is remote from the discharge pump 302. When the bottle-mouth-shaped opening 3015 of the liquid storage box 301 and an end of the discharge pump 302 / hose 204 that is remote from the discharge pump 302 are connected, the bottle-mouth-shaped opening 3015 of the liquid storage box 301 is opened, and when the bottle-mouth-shaped opening 3015 of the liquid storage box 301 and the end of the discharge pump 302 / hose 204 that is remote from the discharge pump 302 are separated, the bottle-mouth-shaped opening 3015 of the liquid storage box 301 is closed. In this way, after the aforementioned liquid storage box 301 is pulled out, the liquid storage box 301 can be removed separately, and then the detergent can be refilled into the liquid storage box 301 again, which is more convenient for the user to add.

[0041] Preferably, in this embodiment, the discharge device further includes a drawer 202, the drawer 202 is installed in the housing 5 so as to be removable through an opening on the housing 5, and the liquid storage box 301 is installed inside the drawer 202.

[0042] Specifically, the opening is located at the front side of the housing 5, and the drawer 202 includes a panel 2021 and a storage section 2022. The shape of the panel 2021 matches the shape of the front side of the housing 5, and the storage section 2022 is groove-shaped with its groove opening facing upward. The front end of the storage section 2022 is connected to the center of the inside of the panel 2021, and the left and right sides of the storage section 2022 are connected to the left and right inner walls of the housing 5 via slide rails and are slidably fitted together, so that when the drawer 202 is pushed in, the panel 2021 abuts against the front end of the housing 5.

[0043] In this embodiment, the discharge pump 302 can be mounted on the storage section 2022 of the drawer 202. In this case, the suction end of the discharge pump 302 communicates with the liquid storage box 301, and the discharge end of the discharge pump 302 communicates with the joint 203 on the housing 5 via the hose 204. Of course, the discharge pump 302 can be mounted on the inner wall of the housing 5, or on the outer wall of the housing 5.

[0044] As shown in Figures 1 and 2, in this embodiment, a discharge pipe 212 is installed on the drawer 202, one end of the discharge pipe 212 is installed inside the storage section 2022 and connected to the liquid storage box 301 in the storage section 2022, and the other end of the discharge pipe 212 extends outside the storage section 2022 and connected to the suction end of the discharge pump 302.

[0045] 15 and 16, one end of the discharge pipe 212 communicates with the discharge pump 302, and the other end passes through the rear wall of the storage section 2022 and is connected to a bottle-mouth-shaped opening 3015 of the liquid storage box 301 in the storage section 2022. Preferably, one end of the discharge pipe 212 communicates with the discharge pump 302, and the other end passes through the rear wall of the storage section 2022 from the bottom of the rear wall, extends into the interior of the storage section 2022, and is bent upward. In addition, the bottle-mouth-shaped opening 3015 of the liquid storage box 301 is disposed facing downward and corresponds to the position of the discharge pipe 212, and an open / close valve that engages with the discharge pipe 212 is provided in the bottle-mouth-shaped opening 3015 of the liquid storage box 301. As the liquid storage box 301 is loaded from top to bottom into the storage section 2022, the end of the aforementioned discharge pipe 212 is pressed against the valve core of the on-off valve, opening the valve core and establishing electrical communication between the liquid storage box 301 and the discharge pump 302.

[0046] 16 , in this embodiment, the bottom of the liquid storage box 301 is provided with an inwardly recessed recess 3016, and the bottle-mouth-shaped opening 3015 is located protruding downward from the top of the recess 3016. A connecting groove 4 is located on the inner wall of the bottom of the container 2022, with its opening facing upward and conforming to the shape of the bottle-mouth-shaped opening 3015 of the liquid storage box 301. One end of the discharge conduit 212, which faces away from the discharge pump 302, extends upward from the bottom of the connecting groove 4, and the bottle-mouth-shaped opening 3015 is fitted into the connecting groove 4 when the liquid storage box 301 is installed. On the one hand, this improves the sealing effect for the bottle-mouth-shaped opening 3015, and on the other hand, it improves the positioning effect and stability of the installation of the liquid storage box 301.

[0047] Preferably, in this embodiment, the connecting groove 4 is located at the rear of the storage compartment 2022, and the bottle-mouth opening 3015 is located at the rear end of the liquid storage box 301. This prevents the connecting groove 4 from interfering with the user's ability to insert other items after the liquid storage box 301 is removed, improving the user's usability.

[0048] In this embodiment, both ends of the liquid storage box 301 are in close contact with the inner wall of the storage section 2022, and a guide structure for guiding the installation of the liquid storage box 301 is installed between the end face of the liquid storage box 301 and the inner wall of the storage section 2022. The guide structure is installed between at least one end of the liquid storage box 301 that is away from the bottle-mouth-shaped opening 3015 and the inner wall of the storage section 2022.

[0060] Preferably, in this embodiment, the base 2 is detachably attached to the bottom of the washing machine body 1 . [Example]

[0061] 1 to 20, an embodiment of the present invention introduces a discharging device. The discharging device may be mounted on a washing machine or on ancillary equipment of the washing machine. For example, the washing machine base 2 only needs to ensure that the discharging device can discharge the detergent stored in the discharging device into the drum assembly 101 of the washing machine.

[0062] The discharging device includes a housing 5 and a liquid storage box 301. An opening is provided on one side of the housing 5, and the liquid storage box 301 can be inserted or removed by pulling it out through the opening. A joint 203 for delivering detergent into the drum assembly 101 of the washing machine is provided on the side wall of the housing 5, and the liquid storage box 301 is connected to the joint 203 via a discharge pump 302 and a hose 204. As a result, the discharge pump 302 can extract the detergent previously stored in the liquid storage box 301 and pump it into the drum assembly 101 of the washing machine via the joint 203.

[0063] In this embodiment, the hose 204 has an extra length to allow the liquid storage box 301 to be removed. As a result, when the user removes the liquid storage box 301, the discharge pump 302 is removed following the liquid storage box 301, and communication is always maintained between the liquid storage box 301 and the joint 203. This prevents the detergent in the liquid storage box 301 from leaking into the housing 5, reduces detergent leakage, ensures the cleanliness of the inside of the housing 5, and improves the user experience.

[0064] In this embodiment, the hose 204 may be a corrugated pipe or a pressure-resistant pipe.

[0065] Preferably, as shown in Figures 7, 8, 19, and 20, a folding arm 208 for guiding deformation of the hose is provided on the hose 204. By providing the folding arm 208 on the hose 204, it is possible to guide the position and movable range of the hose 204 between the liquid storage box 301 and the joint 203, and at the same time, it is possible to improve the guiding ability for the deformation position and deformation width of the hose 204, thereby improving the controllability of the deformation of the hose 204. In addition, it is possible to reduce the interference of the hose 204 with the liquid storage box 301 being pulled out, and it is also possible to reduce wear on the hose 204 caused by being pulled out over a long period of time, improving the user experience and increasing the service life of the hose 204.

[0066] As shown in Figures 19 and 20, in this embodiment, the folding arm 208 is made of a hard material and includes a first guide tube and a second guide tube that are fitted onto the hose 204, and the first guide tube and the second guide tube are hingedly connected to each other.

[0067] Specifically, the first guide tube and the second guide tube each include a accommodating groove 2081 and a position limiting rib 2082.

[0068] In this embodiment, the groove openings of the accommodating grooves 2081 of the first guide tube and the second guide tube are arranged opposite to each other. The hose 204 is installed in the accommodating groove 2081, and a plurality of position limiting ribs 2082 are arranged at intervals at the groove opening positions of the accommodating groove 2081 to limit the hose 204 within the accommodating groove 2081.

[0069] The position limiting rib 2082 extends from the groove opening of the receiving groove 2081 toward the inside of the groove opening in a direction perpendicular to the direction of the receiving groove 2081. The position limiting rib 2082 may be installed on one side of the groove opening or on both sides of the groove opening. Preferably, the position limiting ribs 2082 are installed on both sides of the groove opening, and the position limiting ribs 2082 installed on both sides of the groove opening are arranged alternately.

[0070] In some possible embodiments, after the folding arm 208 is attached, the hose 204 can move axially relative to the folding arm 208, thereby ensuring that the first guide tube and the second guide tube can rotate oppositely. Preferably, the hose 204 is fixedly connected to either the first guide tube or the second guide tube, and axially movably connected to the other of the first guide tube or the second guide tube, thereby ensuring the stability of the relative position between the folding arm 208 and the hose 204 and improving the reliability of the operation of the folding arm 208.

[0071] In some other possible embodiments, both the first guide tube and the second guide tube of the folding arm 208 are connected to the hose 204 with their positions restricted in the axial direction. That is, the hose 204 is firmly fixed in the receiving groove 2081 by the position restricting rib 2082. At least a portion of the hose 204 in the folding arm 208 may be installed in an extendable form, or the hose 204 in the folding arm 208 may be installed with an excess length to allow the first guide tube and the second guide tube to rotate oppositely, which only needs to ensure that the folding arm 208 can be folded smoothly.

[0072] Preferably, in this embodiment, a guide portion 2083 for guiding the bending of the hose 204 is provided at the hinged connection end of the first guide tube and / or the second guide tube.

[0073] The guide portion 2083 is configured by the end of the first guide tube and / or the second guide tube expanding outward along an axial direction perpendicular to the hinge connection axis. In this embodiment, the provision of the guide portion 2083 prevents the formation of dead space at the bending position of the hose 204 when the folding arm 208 is folded, and also accommodates excess length of the hose 204 for bending deformation, thereby allowing the folding arm 208 to be smoothly unfolded and folded.

[0074] Preferably, in this embodiment, the extending direction of the guide portion 2083 is a curve expanding outward from the axis of the hinge connecting shaft, and the curvature of the guide portion 2083 gradually increases in the direction approaching the hinge connecting shaft, thereby enabling the guide portion 2083 to better adapt to the shape of the deformed position when the hose 204 is bent, further improving the guiding effect on the hose 204, preventing the occurrence of dead space when the hose 204 is bent, and improving the operational stability of the discharge device.

[0098] 1 to 20, an embodiment of the present invention introduces a discharging device. The discharging device may be mounted on a washing machine or on ancillary equipment of the washing machine. For example, the washing machine base 2 only needs to ensure that the discharging device can discharge the detergent stored in the discharging device into the drum assembly 101 of the washing machine.

[0099] In this embodiment, the discharging device includes a liquid storage box 301, a cavity for accommodating the liquid storage box 301, and a discharging pump 302, and the liquid storage box 301 is detachably mounted in the cavity. When the liquid storage box 301 is inserted into the cavity, the liquid storage box 301 communicates with the discharging pump 302, and when the liquid storage box 301 is removed, the liquid storage box 301 is disconnected from the discharging pump 302.

[0100] Specifically, as shown in Figures 13 and 15, the liquid storage box 301 is installed in the form of a cartridge. An on-off valve is installed at the bottle-neck-shaped opening 3015 of the liquid storage box 301, and a discharge pipe 212 is installed in the cavity. One end of the discharge pipe 212 communicates with the suction end of the discharge pump 302, and at least a portion of the other end of the discharge pipe 212 extends into the cavity. When the liquid storage box 301 is inserted into the cavity, the bottle-neck-shaped opening 3015 of the liquid storage box 301 corresponds to the end of the discharge pipe 212. During insertion, the end of the discharge pipe 212 is pressed against the valve core of the on-off valve to open the valve core, thereby realizing communication between the liquid storage box 301 and the discharge pump 302.

[0101] In this embodiment, the discharge device may have an independent housing 5, and a cavity is defined by the housing 5. The discharge device may not have an independent housing 5, and the cavity is directly integrated on the washing machine body 1 or on the washing machine base 2.

[0102] 15 , in this embodiment, a connecting groove 4 is further provided inside the cavity, and at least a portion of the discharge pipe 212 extends into the connecting groove 4. The connecting groove 4 is for receiving the bottle-mouth-shaped opening 3015 of the liquid storage box 301 when the liquid storage box 301 is inserted, thereby guiding and positioning the insertion of the liquid storage box 301. At the same time, the connecting groove 4 can also collect detergent leaking from the bottle-mouth-shaped opening 3015 of the liquid storage box 301 when the bottle-mouth-shaped opening 3015 of the liquid storage box 301 and the discharge pipe 212 are connected, preventing the detergent from leaking into the cavity and making it easier to clean up the leaked detergent.

[0103] The groove opening of the connecting groove 4 is oriented parallel to the loading direction of the liquid storage box 301, i.e., the connecting groove 4 is installed toward the loading opening of the liquid storage box 301. The internal shape of the connecting groove 4 matches the shape of the bottle-mouth-shaped opening 3015 of the liquid storage box 301, and the end of the discharge pipe 212 is installed in the connecting groove 4. When the liquid storage box 301 is loaded, the outer wall of the bottle-mouth-shaped opening 3015 is tightly attached to the inner wall of the connecting groove 4, and the end of the discharge pipe 212 is inserted into the bottle-mouth-shaped opening 3015 to open the on-off valve.

[0104] Preferably, in this embodiment, the aforementioned connecting groove 4 is detachably mounted on the inner wall of the cavity. By detachably mounting the connecting groove 4 on the inner wall of the cavity, the user can easily remove and clean the connecting groove 4. Specifically, the user can remove the connecting groove 4, and if it is not too dirty, simply rinse it with water. If it is dirty, the user can soak it in water, and after soaking it for about 10 minutes, lightly scrub the connecting groove 4 with a small brush and then wash it with water to clean it. This prevents clogging of the discharge pipe 212 or the bottle neck opening 3015 and improves the user experience.

[0105] 17, in this embodiment, the connecting groove 4 is detachably mounted on the inner wall of the cavity via an elastic locking member 6. Specifically, the connecting groove 4 comprises a connecting groove base 402 and a connecting groove body 401 that are connected to each other / molded integrally, and an attachment hole 406 is formed on the connecting groove base 402. The elastic locking member 6 is engaged with the attachment hole 406 on the connecting groove base 402, thereby tightly pressing the connecting groove base 402 onto the inner wall of the cavity. The connecting groove body 401 is installed on one side of the connecting groove base 402 away from the inner wall, and the groove opening of the connecting groove body 401 is installed perpendicular to the inner wall of the cavity.

[0106] 15 to 17 , in this embodiment, the end of the discharge pipe 212 is installed in the cavity and extends upward, and the discharge pipe 212 is fixed to the bottom wall of the cavity via connecting parts such as screws and bolts. The connecting groove 4 is installed over the discharge pipe 212, and at least a portion of the end of the discharge pipe 212 extends into the connecting groove body 401. The liquid storage box 301 is installed in the cavity from top to bottom, with the bottle-mouth-shaped opening 3015 of the liquid storage box 301 facing downward. During installation, the bottle-mouth-shaped opening 3015 of the liquid storage box 301 is fitted into the connecting groove body 401, and the discharge pipe 212 is connected to the liquid storage box 301 via the opening / closing valve in the bottle-mouth-shaped opening 3015.

[0107] 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 discharge pipe 212. The connecting groove 4 is fitted to the end of the discharge pipe 212, and the outer wall of the discharge pipe 212 is in close contact with the inner wall of the through hole 404.

[0108] Preferably, in this embodiment, the aforementioned through hole 404 extends upward / downward from the groove bottom of the connecting groove body 401, and the through hole 404 is formed in a sleeve shape, which makes it easier to seal between the through hole 404 and the discharge pipe line 212.

[0109] Preferably, in this embodiment, a fixing boss is installed at the bottom of the discharge pipe 212, and the bottom of the boss is fixedly connected to the bottom wall of the cavity via a screw / bolt. The top of the boss protrudes from the circumferential surface of the discharge pipe 212, and the bottom of the through-hole 404 abuts against the top of the boss.

[0110] Preferably, in this embodiment, a seal ring is installed between the inner wall of the aforementioned through hole 404 and the outer wall of the discharge pipe line 212 .

[0111] More preferably, the sealing ring is fitted onto the discharge pipe 212 and is press-fitted between it and the inner wall of the through-hole 404. Specifically, a groove is formed around the outer wall of the discharge pipe 212, and the sealing ring is fitted into the groove, with at least a portion of the sealing ring protruding from the outer wall of the discharge pipe 212. When the connecting groove 4 is installed, the sealing ring and the through-hole 404 elastically abut against each other, further improving the sealing performance and preventing leaked detergent from flowing into the connecting groove 4 through the gap between the inner wall of the through-hole 404 and the outer wall of the discharge pipe 212.

[0112] 17 , in this embodiment, the elastic locking device 6 includes an elastic arm 601 and a locking protrusion 602. The elastic arm is U-shaped, with one end connected to the periphery of the discharge pipe 212 and the other end extending toward the inner wall of the cavity and then bending to extend away from the inner wall. The locking protrusion 602 is located on a side of the elastic arm 601 facing away from the discharge pipe 212. The side of the locking protrusion 602 facing away from the elastic arm 601 is inclined toward the insertion direction of the connecting groove 4, and the side of the locking protrusion 602 facing the inner wall of the cavity is flat and parallel to the inner wall of the cavity.

[0113] Thus, when the connecting groove 4 is fitted onto the discharge pipe 212 in the installation direction, the bottom of the connecting groove 4 is pressed against the inclined surface of the locking protrusion 602, causing the elastic arm 601 to elastically deform in a direction approaching the discharge pipe 212, allowing the connecting groove 4 to continue moving downward. When the bottom of the connecting groove 4 is in close contact with the inner wall of the cavity, the bottom surface of the locking protrusion 602 becomes flush with the bottom surface of the locking mounting hole 406, the elastic arm rebounds, the locking protrusion 602 enters the locking mounting hole 406 on the connecting groove base 402, and the connecting groove base 402 is positioned between the locking protrusion 602 and the inner wall of the cavity.

[0114] When the user wants to remove the connecting groove 4, he or she only needs to press the elastic arm 601 and / or the locking protrusion 602 in the direction approaching the discharge pipe line 212 to separate the locking protrusion 602 from the locking attachment opening 406.

[0115] In this embodiment, a plurality of discharge pipelines 212 are installed on the inner wall of the aforementioned cavity to respectively connect to a plurality of liquid storage boxes 301, and the aforementioned connecting groove base 402 is installed to cover at least two discharge pipelines 212, and a connecting groove body 401 is provided which corresponds one-to-one with each discharge pipeline 212.

[0116] In some possible embodiments, the connecting groove 4 has two connecting groove bodies 401, and the connecting groove 4 is simultaneously fitted onto two discharge pipes 212. The two connecting groove bodies 401 are respectively fitted onto one corresponding discharge pipe 212. One elastic fastener 6 is respectively installed on each of the two discharge pipes 212, and the connecting groove 4 is fixed by the two elastic fasteners 6 after installation, which can ensure the stability of the installation of the connecting groove 4.

[0117] In some other possible embodiments, the connecting groove 4 has two or more connecting groove bodies 401, and the connecting groove 4 is simultaneously fitted onto a plurality of discharge pipes 212. The number of discharge pipes 212 corresponds one-to-one with the number of connecting grooves 4, and each connecting groove body 401 is fitted onto one discharge pipe 212. In this embodiment, elastic fasteners 6 are installed on at least two discharge pipes 212. That is, the connecting groove 4 is attached to the inner wall of the cavity via at least two elastic fasteners 6, thereby ensuring the stability of the attachment effect of the connecting groove 4.

[0118] Preferably, in this embodiment, when the connecting groove 4 is provided correspondingly on two or more discharge pipes 212, the discharge pipes 212 are arranged in parallel. That is, the discharge pipes 212 are arranged on the same straight line. In this case, the elastic fasteners 6 are arranged on at least the discharge pipes 212 located at both ends. More preferably, the elastic fasteners 6 on the discharge pipes 212 located at both ends are oriented in opposite directions, thereby further ensuring the stability of the mounting effect of the connecting groove 4.

[0119] In this embodiment, a leaked liquid recovery groove 405 is further provided on the aforementioned connecting groove base 402. The leaked liquid recovery groove 405 communicates with the connecting groove main body 401 and is for recovering leaked detergent, making it easier for the user to clean.

[0120] Specifically, the leakage recovery groove 405 is located on one side of the connecting groove body 401, and the opening of the leakage recovery groove 405 is lower than the bottom of the connecting groove body 401, or the opening of the leakage recovery groove 405 is flush with the bottom of the connecting groove body 401, and a flow hole 403 is opened in the bottom of one side wall of the connecting groove body 401 that is close to the leakage recovery groove 405. When the liquid storage box 301 is being loaded or unloaded, the leaked detergent flows into the connecting groove body 401 and then flows along the bottom of the connecting groove body 401 into the leakage recovery groove 405.

[0121] Preferably, in this embodiment, the groove opening of the connecting groove body 401 faces upward, and the groove bottom of the connecting groove body 401 is configured as a slope that slopes downward toward the leaked liquid recovery groove 405. This allows the leaked detergent to flow into the leaked liquid recovery groove 405 at an accelerated rate, and prevents the leaked detergent from accumulating in the connecting groove body 401.

[0122] More preferably, in this embodiment, at least one groove wall of the leaked liquid recovery groove 405 that is close to the connecting groove body 401 is provided as a slope that slopes downward toward the leaked liquid recovery groove 405 side.

[0123] 17 and 18, in this embodiment, the leakage recovery groove 405 is located on one side of the connecting groove 4, away from the elastic stopper 6. That is, the leakage recovery groove 405 and the elastic stopper 6 are located on both sides of the discharge pipe 212, respectively, which makes the structural layout of the connecting groove 4 more reasonable.

[0124] In this embodiment, when multiple connection groove bodies 401 are installed on one connection groove 4, each connection groove body 401 may be connected to one corresponding leakage recovery groove 405, or multiple connection groove bodies 401 may be connected to one leakage recovery groove 405 at the same time.

[0125] Preferably, in this embodiment, each connecting groove body 401 corresponds to and communicates with one leakage recovery groove 405, or multiple connecting groove bodies 401 corresponding to liquid storage boxes 301 storing the same type of detergent correspond to and communicate with the same leakage recovery groove 405. This prevents different types of leaked detergent from mixing, allows users to reuse the detergent collected in the leakage recovery groove 405, and avoids wasting resources.

[0126] In this embodiment, the discharging device further includes an alarm device. The alarm device may be an alarm device of the washing machine itself or may be an alarm device installed separately on the discharging device. A liquid leakage detection device is installed in the liquid leakage collection groove 405. The liquid leakage detection device is communicatively connected to the alarm device and activates the alarm device to issue an alarm when the liquid level in the liquid leakage collection groove 405 reaches a preset value. The installation of the liquid leakage detection device and the alarm device can prompt the user to quickly clean up any leaked detergent collected in the connecting groove 4 and can also prevent excessive detergent from being collected in the liquid leakage collection groove 405 and leaking into the cavity, further improving the user experience.

[0127] In this embodiment, the leakage detection device may be a microswitch, a liquid level sensor, or the like.

[0128] In some possible embodiments, the leakage detection device includes a key, a first pressing piece, and a second pressing piece. When there is no leakage in the leakage recovery groove 405, the key is pressed down, and the first pressing piece and the second pressing piece are in close contact. As the level of the leakage liquid in the leakage recovery groove 405 rises, the key gradually rises, and when the key rises to a certain height, the first pressing piece and the second pressing piece are separated. At this time, the alarm device starts to sound an alarm.

[0129] In this embodiment, the discharge device includes a housing 5 and a drawer 202, and the drawer 202 is retractably installed in the housing 5. The drawer 202 includes a panel 2021 and a storage section 2022 for storing the liquid storage box 301, and the internal space of the storage section 2022 of the drawer 202 forms the cavity. The discharge pump 302 is attached to one side of the storage section 2022 away from the panel 2021, and one end of the discharge pipe 212 is connected to the suction end of the discharge pump 302. The other end of the discharge pipe 212 passes through one side wall of the storage section 2022 away from the panel 2021 and extends into the storage section 2022, and the end of the discharge pipe 212 away from the discharge pump 302 is bent upward and extends. The connecting groove 4 is detachably installed at a position that is the bottom of the connecting groove 4 and corresponds to one end of the discharge pipe line 212 that is remote from the discharge pump 302 . [Example]

[Example]

[0156] As shown in Figures 3 to 20, this embodiment introduces a washing machine base 2. The washing machine base 2 is attached to the bottom of the washing machine and comprises a base body 201 and a drawer 202. The base body 201 is shaped to fit the bottom of the washing machine and has an opening on one side. The opening is shaped to fit the drawer 202, and the drawer 202 is installed within the base body 201 so that it can be pulled out through the opening. By installing the base 2, the height of the washing machine can be raised to a certain extent, making it easier for users to load and remove clothes, and also providing more storage space in the washing machine, making it convenient for storing items such as liquid detergent and powder detergent.

[0157] In this embodiment, the aforementioned opening may be located on any side of the washing machine base 2. Preferably, the opening is located on the front side of the washing machine base 2, making it easier for users to pull out the drawer 202. Of course, the opening may be located on the left, right, or rear side of the base 2, and can be adjusted according to the actual needs of users. In this embodiment, the opening is located on the front side of the base 2 as an example.

[0158] The washing machine base 2 can be applied to a drum type washing machine, a whirlpool type washing machine, or a clothes dryer with a washing function. In this embodiment, a drum type washing machine will be described as an example.

The front end of the storage compartment 2022 is connected to the center of the inner side of the panel 2021, and the left and right sides of the storage compartment 2022 are connected to the left and right inner walls of the base body 201 via slide rails, and are slidably fitted together. When the drawer 202 is pushed in, the panel 2021 abuts against the front end of the base body 201. Preferably, in this embodiment, after the drawer 202 is pushed in, the front surface of the panel 2021 is flush with the front surface of the washing machine, thereby improving the overall appearance and aesthetics of the washing machine.

[0160] In this embodiment, an external discharging module is mounted within the base 2, and the discharge end 305 of the external discharging module is connected to the drum assembly 101 of the washing machine. By installing the external discharging module within the base 2 and further installing the discharge end 305 of the external discharging module so that it is connected to the drum assembly 101 of the washing machine, the washing machine to which the base 2 is attached can add an automatic discharging function to washing machines that do not have a built-in discharging module, and can expand the types and weights of detergent that can be stored in washing machines that have a built-in discharging module, eliminating the need for users to frequently add detergent to the washing machine and improving the user experience.

[0161] In this embodiment, the external discharging module is specifically mounted on the drawer 202 of the base 2, and includes a liquid storage box 301 for storing detergent and a discharging pump 302 for sucking the detergent. The external discharging module may directly discharge the detergent into the drum assembly 101, or may inject the detergent into the water intake pipeline, mix the detergent with the water intake flow, and then inject the detergent into the drum assembly 101. In this embodiment, the case where the built-in discharging module injects detergent into the water intake flow will be described as an example.

[0162] In this embodiment, the liquid storage box 301 is detachably mounted inside the storage section 2022, and the discharge pump 302 of the external discharge module is mounted outside the storage section 2022. The liquid storage box 301 is mounted inside the drawer 202 of the base 2, and furthermore, the liquid storage box 301 is installed so as to be detachably mounted inside the storage section 2022 of the drawer 202. Therefore, when the detergent in the liquid storage box 301 runs out, the user can first remove the liquid storage box 301 and then add more detergent, which reduces the difficulty for the user in filling the liquid storage box 301 with detergent and improves the user experience.

[0163] In this embodiment, the aforementioned liquid storage box 301 is loaded along the pull-out direction of the drawer 202, the length of the aforementioned liquid storage box 301 is the same as the distance between the front and rear inner walls of the storage section 2022, and the front and rear ends of the liquid storage box 301 are respectively closely adjacent to the front and rear inner walls of the storage section 2022.

[0164] Preferably, the left and right side walls of the liquid storage box 301 can be closely fitted to the left and right inner walls of the storage section 2022, i.e., the liquid storage box 301 occupies the entire interior space of the storage section 2022, thereby ensuring the storage amount of detergent. Alternatively, the liquid storage box 301 can be installed to occupy only a portion of the interior space of the storage section 2022, thereby preserving a certain amount of interior space in the storage section 2022 for storing other items. In this embodiment, the pre-reserved space in the storage section 2022 can be installed on the left, right, or both the left and right sides of the liquid storage box 301. That is, the liquid storage box 301 can be installed on the right, left, or center of the storage section 2022, as long as it is ensured that the storage section 2022 can also store other items.

[0165] In this embodiment, a plurality of the liquid storage boxes 301 can be installed, each used to store the same or different types of detergent. The plurality of liquid storage boxes 301 can be installed in parallel inside the storage section 2022 to occupy the internal space of the storage section 2022. In addition, a space reserved in advance for storing other miscellaneous items can be installed on the left and / or right sides of the plurality of liquid storage boxes 301 installed in parallel.

[0166] Preferably, the base 2 can have a plurality of liquid storage boxes 301 arranged therein to occupy the internal space of the storage section 2022. When the storage section 2022 needs to be used to store other miscellaneous items, one or more liquid storage boxes 301 can be selectively removed, allowing the user to easily adjust according to actual needs.

[0167] In this embodiment, the discharge pump 302 of the external discharge module is installed at one end of the storage section 2022 away from the panel 2021, that is, the discharge pump 302 is attached to the rear side of the storage section 2022, and the discharge pump 302 is connected to the liquid storage box 301 in the storage section 2022 via the discharge pipeline 212.

[0224] Preferably, in this embodiment, different types of detergent are stored in the four liquid storage boxes 301 of the above-mentioned external discharge module, and when the external discharge module is operating, the operation of any one or more discharge pumps 302 is controlled, and the detergent in the corresponding liquid storage box 301 is discharged into the cleaning flow path of the distribution box 303, and after being washed and diluted by the intake water flow, flows into the drum assembly 101. [Example]

[0225] This embodiment discloses a method for controlling a washing machine, which specifically includes the following steps: S1: Turn on the power. S2: Obtain information about the clothes to be washed. S3: Select detergent based on information about the clothes to be washed. S3.1: If the selected detergent is stored in the built-in liquid storage box, the built-in release module in the washing machine main body 1 is controlled to release it. S3.2: If the selected detergent is stored in the liquid storage box 301, control the external discharging module to discharge it.

[0226] In this embodiment, a database is built in the system of the washing machine, and when a user fills the built-in liquid storage box with detergent, the user inputs the detergent information of the detergent into the system.

[0227] Specifically, the washing machine is provided with an information input port. When a user needs to add detergent to the built-in dispensing module, the user can align the detergent packaging bottle / bag prepared for filling the built-in dispensing module with the information input port. The information input port on the washing machine scans an identification code, such as a 2D code or barcode, on the detergent packaging bottle / bag to obtain the detergent type and electronic instruction manual, and then obtains detergent information from there. The user can also manually input detergent information.

[0228] In some possible embodiments, the external dispensing module is installed on the washing machine, and the detergent information stored in the liquid storage box 301 of the external dispensing module is input into the database of the washing machine system through an information input port on the washing machine. When dispensing detergent, the washing machine directly matches the most suitable detergent in the washing machine database based on the information of the laundry to be washed, and controls the built-in dispensing module or the external dispensing module to dispense it.

[0229] In some possible embodiments, the external dispensing module has an independent database, and when the external dispensing module is connected to the washing machine, the detergent information stored in the liquid storage box 301 of the external dispensing module is input into the database of the external dispensing module through an information input port on the washing machine and stored separately. When the washing machine dispenses detergent, the washing machine system synchronously obtains the detergent information in the database of the external dispensing module, matches the most suitable detergent in the database of the washing machine and the database of the external dispensing module according to the information of the laundry to be washed, and then controls the built-in dispensing module or the external dispensing module to dispense.

[0230] In this embodiment, an independent database is established for the external dispensing module, so that when the external dispensing module is removed, there is no need to update the detergent information written in the washing machine database. At the same time, when an external dispensing module that already stores detergent is installed on a washing machine, there is no need to re-enter the detergent information stored in the external dispensing module, making it easier to install and remove the external dispensing module and ensuring the accuracy of the detergent information read by the washing machine system.

[0231] Preferably, in this embodiment, a Wi-Fi unit is further installed on the external dispensing module. A user can connect the external dispensing module to a mobile terminal such as a mobile phone via the Wi-Fi unit to obtain detergent information stored in the external dispensing module and then transmit the detergent information to the washing machine. Alternatively, the washing machine can directly connect to the external dispensing module via the Wi-Fi unit to obtain the detergent information stored in the external dispensing module.

[0232] In this embodiment, the external dispensing module can also write detergent information stored in the external dispensing module via a mobile device connected to the associated Wi-Fi module. Specifically, when a user needs to add detergent to the external dispensing module, they can use their mobile phone to scan an identification code, such as a 2D code or barcode, on the detergent bottle / bag prepared for filling into the built-in dispensing module to obtain the detergent type and electronic instruction manual, and then obtain detergent information from the code. The obtained detergent information can then be written into the external dispensing module's database via the Wi-Fi module. After the external dispensing module is installed on a washing machine, when the washing machine needs to dispense detergent, the washing machine's system synchronously obtains the detergent information stored in the external dispensing module. This allows the external dispensing module to load detergent and input the corresponding detergent information without connecting to the washing machine, improving the user experience.

[0233] Preferably, in this embodiment, the information about the laundry to be washed includes at least the color of the laundry to be washed.

[0234] In this embodiment, a first detergent for washing light-colored clothes is stored in the built-in liquid storage box of the built-in discharging module, and a second detergent for washing dark-colored clothes is stored in the liquid storage box 301 of the external discharging module.

[0235] After the washing machine is turned on, the drum assembly 101 operates at a preset rotation speed to loosen the clothes to be washed.

[0236] An image of the inside of the drum assembly 101 is acquired, and based on the image of the inside of the drum assembly 101, the built-in ejection module and / or the external ejection module is selected and ejected. [Example]

[0237] In this embodiment, a method for controlling a washing machine is disclosed, which specifically includes the following steps: S1.0: At the time of intake, obtain the temperature of the intake water flow. S2.0: If the temperature of the intake water stream is equal to or greater than a preset temperature, the intake line communicates with the built-in discharge module. S3.0: If the temperature of the intake water stream is below a preset temperature, the intake line communicates with the external discharge module in the base 2.

[0238] In this embodiment, detergents are stored according to their optimum washing temperatures. Specifically, detergents with higher optimum washing temperatures are stored in the built-in liquid storage box of the discharging device, and detergents with lower optimum washing temperatures are stored in the liquid storage box 301 of the external discharging module. On the one hand, the high-temperature intake water flow is directly introduced into the drum assembly 101 from the first water inlet 102 of the washing machine and the built-in discharging module, thereby reducing heat loss of the intake water flow and improving washing efficiency. On the other hand, the high-temperature intake water flow can be prevented from damaging the pipes of the external discharging module, thereby improving the service life of the external discharging module.

[0239] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any way. The present invention has been disclosed above through preferred embodiments, but is not intended to limit the present invention. Those skilled in the art can make slight changes or modifications using the technical content shown above to create equivalent embodiments that are equivalently changed within the scope of the technical solutions of the present invention, and can also combine or replace the embodiments in the above embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solutions of the present invention still fall within the scope of the present invention.
