Description

Technical Field

[0001] The utility model belongs to the technical field of washing machines, and in particular relates to an intelligent washing machine with a self-service laundry liquid dispensing device. Background Art

[0002] By installing weight sensors and water level sensors in the washing tub, the smart washing machine can accurately transmit the weight of the clothes and the water level to the self-service laundry detergent dispensing device, so that the self-service laundry detergent dispensing device automatically dispenses laundry detergent into the washing tub according to the detected data, thereby reducing the tedious steps of manually adding laundry detergent and saving time and energy.

[0003] When the self-service laundry detergent dispensing device has been used for a long time, the storage box needs to be extracted from the smart washing machine and cleaned. When extracting the storage box, the delivery pipe needs to be pulled out from the storage box. Since there will be residual laundry detergent inside the delivery pipe, after the delivery pipe is separated from the storage box, the residual laundry detergent inside the delivery pipe will flow into the slot for storing the storage box. This phenomenon causes the storage slot to be cleaned additionally every time the storage box is cleaned, thereby increasing the workload and difficulty of cleaning.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0030] The following will clearly and completely describe the technical solutions in the utility model embodiments in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0031] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0032] See also Figures 1-8 As shown, the utility model is an intelligent washing machine with a self-service laundry detergent dispensing device, comprising a washing machine body 1, a storage assembly 2 is provided inside the washing machine body 1, an extraction assembly 3 is provided on the back of the storage assembly 2, a transfer assembly 4 is provided inside the storage assembly 2, an extraction end of the extraction assembly 3 is provided inside the transfer assembly 4, a pushing assembly 5 is movably connected inside the extraction assembly 3, a pulling assembly 6 is provided on the front of the washing machine body 1, and the pulling assembly 6 is connected to the pushing assembly 5;

[0033] The storage component 2 is used to store laundry liquid, the extraction component 3 extracts the laundry liquid inside the storage component 2 through the transfer component 4, and the pulling component 6 is used to pull the pushing component 5 so that the pushing component 5 pushes the residual laundry liquid inside the extraction component 3 to the inside of the transfer component 4.

[0034] The extraction component 3 can extract the laundry liquid stored in the storage component 2 through the transfer component 4, and the extracted laundry liquid flows directly into the interior of the washing machine body 1 under the guidance of the extraction component 3; when cleaning the storage component 2, the pushing component 5 is first pulled by the pulling component 6, so that the pushing component 5 can move inside the extraction end of the extraction component 3, and the moving pushing component 5 can push the laundry liquid remaining in the extraction component 3 to the interior of the transfer component 4, and then the storage component 2 is extracted from the interior of the washing machine body 1 and cleaned.

[0035] By pulling the pushing component 5 through the pulling component 6, the pushing component 5 can push the laundry liquid remaining at the extraction end of the extraction component 3 into the interior of the transfer component 4. At the same time, the laundry liquid inside the transfer component 4 will not flow out under the cover of the pushing component 5. The above arrangement prevents laundry leakage when the storage end of the storage component 2 is moved out from the interior of the washing machine body 1, so that when cleaning, only the storage end of the storage component 2 needs to be cleaned, thereby reducing the workload and difficulty of cleaning.

[0036] In one embodiment, for the above-mentioned storage component 2, the storage component 2 includes a storage slot 201, the storage slot 201 is opened on the front of the washing machine body 1, the storage slot 201 is movably connected to the storage box 202, and the front of the storage box 202 is fixedly connected to a handle 203.

[0037] By pulling the storage box 202 with the handle 203, the storage box 202 can be moved out from the interior of the storage groove 201. This arrangement allows the interior of the storage box 202 to be cleaned outside the washing machine body 1, making the entire cleaning process more convenient.

[0038] In one embodiment, for the above-mentioned extraction component 3, the extraction component 3 includes an installation cavity 301, the installation cavity 301 is opened inside the body of the washing machine main body 1, and an extraction pump 302 is fixedly installed on the inner wall of the installation cavity 301. An extraction hole 303 is opened on the inner wall of the storage groove 201, and the extraction hole 303 extends to the interior of the installation cavity 301. The interior of the extraction hole 303 is movably connected with a T-shaped extraction tube 304, and the T-shaped extraction tube 304 is fixedly connected to the extraction end of the extraction pump 302. The output end of the extraction pump 302 is fixedly connected with a delivery tube 305, and one end of the delivery tube 305 extends to the interior of the washing machine main body 1.

[0039] When the controller receives the signals transmitted by the weight sensor and the water level sensor, the controller can control the extraction pump 302. At this time, the extraction pump extracts the laundry liquid stored in the storage box 202 through the T-shaped extraction tube 304. The extracted laundry liquid flows directly into the interior of the washing machine body 1 under the guidance of the delivery tube 305.

[0040] In one embodiment, for the above-mentioned transfer component 4, the transfer component 4 includes a transfer cavity 401, and the transfer cavity 401 is opened inside the box body of the storage box 202. A transfer hole 402 is opened on the top of the inner wall of the transfer cavity 401, and the transfer hole 402 extends to the interior of the storage box 202. A transfer tube 403 is fixedly connected to the transfer hole 402 corresponding to the top of the inner wall of the transfer cavity 401. One end of the transfer tube 403 passes through the storage box 202 and is connected to the extraction hole 303. A connecting groove 404 is opened on one end of the transfer tube 403, and the T-shaped extraction tube 304 is movably connected to the connecting groove 404.

[0041] The laundry liquid inside the storage box 202 flows directly to the inside of the transfer pipe 403 through the transfer hole 402, so that the T-shaped extraction tube 304 inside the connecting groove 404 extracts the laundry liquid inside the transfer pipe 403. The above-mentioned extraction method enables the T-shaped extraction tube 304 to better extract the laundry liquid inside the storage box 202; when the storage box 202 moves out from the inside of the storage groove 201, the T-shaped extraction tube 304 also moves out directly from the inside of the connecting groove 404. The setting of the connecting groove 404 makes the diameter of the T-shaped extraction tube 304 larger than that of the transfer pipe 403, so that the pushing end of the pushing component 5 moving out from the inside of the T-shaped extraction tube 304 can better block and seal the transfer pipe 403.

[0042] In one embodiment, for the above-mentioned pushing component 5, the pushing component 5 includes a pushing plate 501, which is movably connected to the T-shaped extraction tube 304, and a pushing rod 502 is fixedly connected to one side of the pushing plate 501. One end of the pushing rod 502 passes through the transfer tube 403 and extends to the interior of the transfer cavity 401. One end of the T-shaped extraction tube 304 is fixedly connected to a pressure relief pipe 503, and one end of the pressure relief pipe 503 extends to the outside of the washing machine body 1. A filter 504 is provided at the pipe mouth of the pressure relief pipe 503.

[0043] After the storage box 202 is moved into the storage groove 201, the other end of the T-shaped extraction tube 304 can be directly moved into the connecting groove 404. At this time, the push rod 502 is moved, and the push plate 501 can be moved into the T-shaped extraction tube 304 under the push of the push rod 502. When the push plate 501 moves to the other end of the T-shaped extraction tube 304, the movement of the push rod 502 is stopped. The setting of the T-shaped extraction tube 304 allows the push plate 501 to remove the residual laundry detergent in the T-shaped extraction tube 304. The pushing plate 501 pushes the laundry detergent, and at the same time, when the T-shaped extraction tube 304 extracts the laundry detergent, the pushing plate 501 does not cause any obstruction; when the pushing plate 501 moves inside the T-shaped extraction tube 304, the gas inside the T-shaped extraction tube 304 can flow out through the pressure relief tube 503, so that the pushing plate 501 can move normally inside the T-shaped extraction tube 304, and at the same time, when the T-shaped extraction tube 304 extracts the laundry detergent, the pressure relief tube 503 does not affect the suction force of the T-shaped extraction tube 304 under the shielding of the moving plate 501.

[0044] In one embodiment, for the above-mentioned pulling assembly 6, the pulling assembly 6 includes a pulling rod 601, the pulling rod 601 is connected to the pushing rod 502, one end of the pulling rod 601 passes through the storage box 202 and is fixedly connected to the pulling plate 602, the inner wall of the transfer cavity 401 is fixedly connected to the guide frame 603, and the pulling rod 601 is movably connected to the guide frame 603.

[0045] When cleaning the storage box 202, first pull the push rod 502 through the pull plate 602 and the pulling rod 601, so that the pushing plate 501 can be moved to the inside of the transfer tube 403 under the drive of the pushing rod 502. At this time, the laundry liquid remaining in the T-shaped extraction tube 304 can be directly pushed into the inside of the transfer tube 403, and then the storage box 202 is moved out from the inside of the storage groove 201. When the pulling rod 601 moves, the guide frame 603 can guide the pulling rod 601, so that the stability of the pulling rod 601 during movement can be guaranteed.

[0046] In one embodiment, for the above-mentioned storage box 202, the front of the storage box 202 is fixedly connected to the installation box 604, the pull rod 601 is movably connected to the installation box 604, and a fixing hole 605 is opened on the top of the installation box 604. The fixing hole 605 passes through the pull rod 601, and two fixing holes 605 are provided on the pull rod 601. The fixing holes 605 on the installation box 604 are movably connected to a T-shaped fixing rod 606 inside, and the outer surface of the T-shaped fixing rod 606 is fixedly connected to a connecting plate 607, and a spring 608 is fixedly connected between the top of the connecting plate 607 and the top of the inner wall of the installation box 604, and a ball 609 is provided at the bottom end of the T-shaped fixing rod 606.

[0047] By pulling the T-shaped fixing rod 606 upward and moving the T-shaped fixing rod 606 out of the fixing hole 605 on the pulling rod 601, the pushing rod 502 and the pushing plate 501 are pulled by the pulling rod 601. In this process, the T-shaped fixing rod 606 can be loosened. When the pushing plate 501 pushes the laundry liquid remaining in the T-shaped extraction tube 304 into the interior of the transfer tube 403, the spring 608 pushes the T-shaped fixing rod 606 downward through the connecting plate 607, so that The T-shaped fixing rod 606 is moved to the inside of another fixing hole 605. With the above arrangement, no matter whether the pushing plate 501 is inside the T-shaped extraction tube 304 or inside the transfer tube 403, the pulling rod 601 will not move at will, thereby ensuring the overall stability of the pushing plate 501; when the pulling rod 601 moves, the ball 609 can roll inside the pulling rod 601, and this arrangement reduces the friction between the pulling rod 601 and the T-shaped fixing rod 606.

[0048] Through the above technical solution, 1. the pushing component 5 is pulled by the pulling component 6, so that the pushing component 5 can push the laundry liquid remaining at the extraction end of the extraction component 3 into the interior of the transfer component 4, and at the same time, the laundry liquid inside the transfer component 4 will not flow out under the cover of the pushing component 5. The above arrangement makes it possible for the laundry to not leak when the storage end of the storage component 2 is moved out from the interior of the washing machine body 1, so that when cleaning, only the storage end of the storage component 2 needs to be cleaned, thereby reducing the workload and difficulty of cleaning; 2. the T-shaped fixing rod 606 is pulled and pulled out from the fixing hole on the pulling rod 601 605 moves out, and then the pushing rod 502 and the pushing plate 501 are pulled by the pulling rod 601. When the pushing plate 501 pushes the laundry liquid remaining in the T-shaped extraction tube 304 to the inside of the transfer tube 403, the spring 608 pushes the T-shaped fixing rod 606 downward through the connecting plate 607, so that the T-shaped fixing rod 606 moves to the inside of another fixing hole 605. With the above arrangement, no matter whether the pushing plate 501 blocks the T-shaped extraction tube 304 or the transfer tube 403, the pulling rod 601 will not move at will, so that the stability of the pushing plate 501 during the blocking operation can be guaranteed.
