Description

Technical Field

[0001] This application relates to the field of washing machines, and more particularly to a feeding device for a washing machine. Background Technology

[0002] Washing machines, as a common type of textile processing equipment, play a vital role in the cleaning process of dark-colored polyester fabrics after dyeing. With the development of the textile industry, the demands for cleaning efficiency and quality are constantly increasing, prompting the emergence of various efficient and reliable washing technologies. These technologies not only improve production efficiency and reduce resource consumption but also significantly enhance product quality and market competitiveness.

[0003] Chinese Patent No. CN219364042U discloses a flat-width washing machine. The flat-width washing machine includes a machine body, a washing tank mounted on the machine body, and multiple washing rollers disposed within the washing tank. The multiple washing rollers are spaced apart along the fabric transport direction, with each washing roller parallel to the others and adjacent washing rollers arranged in a staggered, vertical arrangement.

[0004] Regarding the aforementioned technologies, a certain amount of cleaning agent typically needs to be added to the washing machine during use. This is usually done manually, which relies heavily on the operator's experience and judgment. Therefore, due to the lack of precise measurement methods, manual addition can easily lead to adding too much or too little cleaning agent. Too much cleaning agent results in unnecessary waste and increased production costs; while too little may fail to achieve the desired cleaning effect. Utility Model Content

[0005] In order to accurately add cleaning agent into the washing machine body and reduce the waste of cleaning agent, this application provides a feeding device for a washing machine.

[0006] The feeding device for a washing machine provided in this application adopts the following technical solution:

[0007] A feeding device for a washing machine includes a frame and a storage bin. The frame is connected to the washing machine body, and the storage bins are all connected to the frame. A support block is connected to the bottom of each storage bin, and the length direction of the support block is consistent with the length direction of the storage bin. A feeding rod is rotatably connected to the support block, and the length direction of the feeding rod is consistent with the length direction of the support block. A feeding cavity is formed around the feeding rod, and a discharge port is formed at the bottom of the support block. A connecting port is formed at the bottom of the storage bin. A rotating component is connected to the support block, and the rotating component is used to drive the feeding rod to rotate and cause the feeding cavity to intermittently connect with the connecting port or the discharge port. When the feeding cavity is connected with the connecting port, the feeding cavity is not connected with the discharge port.

[0008] By adopting the above technical solution, when cleaning agent needs to be added to the washing machine, the rotating component drives the feeding rod to rotate, so that the feeding chamber is connected to the connecting port, allowing the cleaning agent in the storage tank to enter the feeding chamber through the connecting port. When the feeding chamber is full of cleaning agent, the rotating component drives the feeding rod to rotate, so that the feeding chamber is connected to the discharge port, and the cleaning agent is discharged from the feeding chamber through the discharge port. The cleaning agent is added to the washing machine through the feeding chamber, thereby quantitatively adding cleaning agent to the washing machine, thereby improving the cleaning effect and reducing the waste of cleaning agent.

[0009] Optionally, the support block has a rotating cavity, the length direction of which is consistent with the length direction of the support block. The feeding rod is rotatably connected to the rotating cavity. The rotating cavity is connected to the connecting port and the discharge port. The length direction of the feeding cavity is consistent with the length direction of the feeding rod. A scraper is connected to the inner wall of the feeding cavity, the length direction of which is consistent with the length direction of the feeding cavity. One end of the scraper is connected to the inner wall of the feeding cavity, and the other end of the scraper is in contact with the inner wall of the rotating cavity.

[0010] By adopting the above technical solution, during feeding, the cleaning agent in the storage tank enters the feeding chamber through the connecting port. The rotating part drives the feeding rod to rotate. When the feeding rod rotates, it brings the cleaning agent closer to the discharge port. The scraper follows the rotation of the feeding rod and cleans the inner wall of the rotating chamber. In this way, the cleaning agent adheres to the inner wall of the rotating chamber and accelerates the discharge of the cleaning agent from the feeding chamber.

[0011] Optionally, the frame is connected to a water outlet pipe, the length direction of which is consistent with the length direction of the discharge port. One end of the water outlet pipe is connected to a water supply source, and the water outlet pipe is connected to a plurality of nozzles. The plurality of nozzles are distributed at intervals along the length direction of the water outlet pipe, and the water outlet of the nozzles faces the discharge port.

[0012] By adopting the above technical solution, when the feeding chamber is connected to the discharge port, the nozzle sprays water towards the discharge port, so that the cleaning agent dissolves in the water and accelerates the discharge of the cleaning agent from the feeding chamber.

[0013] Optionally, the support block is connected to a first motor, and the output shaft of the first motor is connected to a striking plate, which is used to strike the support block.

[0014] By adopting the above technical solution, when the cleaning agent enters the feeding chamber through the connecting port, the first motor drives the striking plate to rotate, causing the striking plate to strike the support block, thereby causing the feeding rod to vibrate. This reduces air bubbles in the cleaning agent in the feeding chamber and speeds up the entry of the cleaning agent into the feeding chamber. When the feeding chamber is connected to the discharge port, the striking plate strikes the support block, causing the feeding rod to vibrate, thereby speeding up the discharge of the cleaning agent from the feeding chamber.

[0015] Optionally, the rotating component is a second motor, which is connected to one end of the support block. The output shaft of the second motor is connected to a connecting rod. The rotating cavity has a moving port at one end along its length. The feeding rod is slidably connected to the rotating cavity and the moving port along its length. The connecting rod is connected to a locking component, and the feeding rod is detachably connected to the connecting rod through the locking component.

[0016] By adopting the above technical solution, when the amount of cleaning agent added changes, it is necessary to replace the feeding rod with a feeding chamber of different sizes. When replacing the feeding rod, the feeding rod is unlocked from the connecting rod and moved along the length of the feeding rod so that the feeding rod is away from the support block. This facilitates the replacement or cleaning of the feeding rod and makes it easier to adapt to different amounts of cleaning agent.

[0017] Optionally, a connecting groove is provided at the end of the rotating cavity away from the moving port. A sleeve is connected to one end of the feeding rod. The central axis of the sleeve is collinear with the central axis of the feeding rod. The sleeve is rotatably connected to the connecting groove. The connecting rod is rotatably connected to the inner wall of the connecting groove. The sleeve is fitted onto the connecting rod. The central axis of the connecting rod is collinear with the central axis of the sleeve. An installation groove is provided on the periphery of the connecting rod. The length direction of the installation groove is consistent with the radial direction of the connecting rod. The locking assembly includes a first spring and a locking block. The length direction of the first spring is consistent with the length direction of the installation groove. One end of the first spring is connected to the inner wall of the installation groove. The other end of the first spring is connected to the locking block. The locking block is slidably connected to the installation groove along the length direction of the installation groove. A locking groove is provided on the inner wall of the sleeve. The locking block is embedded in the locking groove.

[0018] By adopting the above technical solution, when installing the feeding rod, it moves along the length direction of the feeding rod, so that the feeding rod slides along its length direction and is connected to the moving port and the rotating cavity, so that the sleeve is embedded in the connecting groove and the sleeve is fitted onto the connecting rod. When the sleeve slides along its length direction and is connected to the connecting rod, the inner wall of the sleeve drives the locking block to be embedded in the mounting groove. The locking block compresses the first spring and drives the first spring to deform. When the locking block approaches the locking groove, the first spring returns to its shape and pushes the locking block to slide along the length direction of the mounting groove and be connected to the mounting groove. The first spring drives the locking block to be embedded in the locking groove, thereby making the sleeve stably connected to the connecting rod and the feeding rod stably set in the rotating cavity.

[0019] Optionally, the locking block is provided with guide surfaces on both sides along the length of the feeding rod. The guide surfaces are inclined and facilitate the locking block to be embedded in or away from the locking groove.

[0020] By adopting the above technical solution and adding a guide surface, it is easier to embed the locking block into or away from the locking groove, and it is also easier to disassemble and assemble the feeding rod.

[0021] Optionally, a pull rod is connected to the end of the feeding rod near the moving port. The length direction of the pull rod is consistent with the length direction of the feeding rod, and an annular groove is provided at the end of the pull rod away from the feeding rod.

[0022] By adopting the above technical solution and adding a pull rod, when disassembling the feeding rod, the operator can hold the pull rod through the annular groove, which makes it easier for the operator to move the feeding rod and facilitates the disassembly and assembly of the feeding rod.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When cleaning agent needs to be added to the washing machine, the rotating part drives the feeding rod to rotate, so that the feeding chamber is connected to the connecting port, allowing the cleaning agent in the storage tank to enter the feeding chamber through the connecting port. When the feeding chamber is full of cleaning agent, the rotating part drives the feeding rod to rotate, so that the feeding chamber is connected to the discharge port, and the cleaning agent is discharged from the feeding chamber through the discharge port. The cleaning agent is added to the washing machine through the feeding chamber, thus adding a metered amount of cleaning agent to the washing machine, thereby improving the cleaning effect and reducing the waste of cleaning agent;

[0025] 2. During feeding, the cleaning agent in the storage tank enters the feeding chamber through the connecting port. The rotating part drives the feeding rod to rotate. When the feeding rod rotates, it brings the cleaning agent closer to the discharge port. The scraper follows the rotation of the feeding rod and cleans the inner wall of the rotating chamber. In this way, the cleaning agent adheres to the inner wall of the rotating chamber and accelerates the discharge of the cleaning agent from the feeding chamber.

[0026] 3. When the amount of cleaning agent added changes, the feeding rod with a different size feeding chamber needs to be replaced. When replacing the feeding rod, the feeding rod is unlocked from the connecting rod and moved along the length of the feeding rod so that the feeding rod is away from the support block. This makes it easier to replace or clean the feeding rod and adapt to different amounts of cleaning agent. Attached Figure Description

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses a feeding device for a washing machine. (Refer to...) Figure 1 and Figure 2 A feeding device for a washing machine includes a frame 100, a storage bin 200, and a support block 300. The frame 100 is connected to the top of the washing machine body. The length of the storage bin 200 is aligned with the width of the washing machine body, and both ends of the storage bin 200 are connected to the frame 100 along its length. The length of the support block 300 is aligned with the length of the storage bin 200, and the top of the support block 300 is connected to the bottom of the storage bin 200. Both ends of the support block 300 are connected to the frame 100 along its length.

[0035] Reference Figure 1 and Figure 3 The support block 300 has a rotating cavity 310, the length of which is aligned with the length of the support block 300. A feeding rod 400 is connected inside the rotating cavity 310, the length of which is aligned with the length of the support block 300, and the feeding rod 400 is rotatably connected to the rotating cavity 310. A feeding cavity 410 is also formed around the feeding rod 400, the length of which is aligned with the length of the feeding rod 400, and the feeding cavity 410 communicates with the rotating cavity 310. A rotating component is connected to the support block 300, which drives the feeding rod 400 to rotate.

[0036] Reference Figure 1 and Figure 3The rotating cavity 310 has a discharge port 320 at its bottom, with the length of the discharge port 320 aligned with the length of the rotating cavity 310. The storage tank 200 has a connecting port 210 at its bottom, with the length of the connecting port 210 aligned with the length of the rotating cavity 310. The rotating cavity 310 has a connecting port 330 at its top, with the length of the connecting port 330 aligned with the length of the rotating cavity 310, and the connecting port 330 is connected to the connecting port 210. The rotating component drives the feeding rod 400 to rotate and causes the feeding cavity 410 to intermittently connect with either the connecting port 210 or the discharge port 320. When the feeding cavity 410 is connected to the connecting port 210, it is not connected to the discharge port 320.

[0037] In use, the storage tank 200 inputs cleaning agent into the feeding chamber 410. When the cleaning agent fills the feeding chamber 410, the rotating component drives the feeding rod 400 to rotate, so that the feeding chamber 410 is connected to the discharge port 320, thereby facilitating the discharge of the cleaning agent from the feeding chamber 410.

[0038] Reference Figure 1 and Figure 3 The storage bin 200 has an opening at the top, and an opening / closing plate 220 is connected to the top of the storage bin 200. The opening / closing plate 220 is used to open or close the opening at the top of the storage bin 200. The opening / closing plate 220 is detachably connected to the storage bin 200 by bolts. The bolts pass through the opening / closing plate 220 in the vertical direction and are threaded to the processing bin.

[0039] Reference Figure 3 The storage bin 200 has guide plates 230 connected to both sides along its width direction. The two guide plates 230 are located on both sides of the connecting opening 210 along the width direction of the storage bin 200. The length direction of the guide plates 230 is consistent with the length direction of the storage bin 200, and both ends of the guide plates 230 along their length direction are connected to the corresponding inner walls of the storage bin 200. One side of the guide plate 230 along its width direction is connected to the inner wall of the storage bin 200, and the other end of the guide plate 230 is inclined downwards and connected to the bottom inner wall of the storage bin 200.

[0040] Reference Figure 3 A support block 300 is connected to a first motor 340, and the output shaft of the first motor 340 is connected to a striking plate 341, which is used to strike the support block 300. A scraper 411 is connected to one inner wall of the feeding chamber 410 along its width direction, and the length direction of the scraper 411 is consistent with the length direction of the feeding chamber 410. One end of the scraper 411 is connected to the inner wall of the feeding chamber 410, and the other end of the scraper 411 contacts the inner wall of the rotating chamber 310.

[0041] Reference Figure 3 and Figure 4The frame 100 is connected to two water outlet pipes 500, the length of which is aligned with the length of the discharge port 320. The two water outlet pipes 500 are spaced apart along the width of the support block 300, with the discharge port 320 located between them. One end of each water outlet pipe 500 is connected to a water supply source (not shown in the figure), which includes a water delivery pipe and a pressure pump. One end of the water delivery pipe is connected to the water outlet pipe 500, and the other end is connected to the pressure pump. Several nozzles 510 are connected to each water outlet pipe 500, spaced apart along its length. The nozzles 510 connected to the two water outlet pipes 500 are staggered. The water outlets of the nozzles 510 are angled towards the side closest to the discharge port 320, and the water outlets of the nozzles 510 are oriented towards the discharge port 320. When the feeding rod 400 rotates and drives the feeding chamber 410 to connect with the discharge port 320, the nozzle 510 on one side sprays water toward the discharge port 320. When the rotating part drives the feeding rod 400 to rotate, so that the opening of the feeding chamber 410 faces the nozzle 510 on the other side, the nozzle 510 on the other side sprays water toward the discharge port 320, thereby dissolving the cleaning agent in the water and accelerating the discharge of the cleaning agent from the feeding chamber 410.

[0042] Reference Figure 4 and Figure 5 The rotating cavity 310 has a movable opening 311 at one end along its length. A connecting groove 312 is formed on the inner wall of the rotating cavity 310 at the end away from the movable opening 311. The length direction of the connecting groove 312 is consistent with the length direction of the rotating cavity 310. The rotating component is a second motor 110, which is connected to the frame 100 and located at the end of the rotating cavity 310 away from the movable opening 311. A connecting rod 120 is connected to the output shaft of the second motor 110. The length direction of the connecting rod 120 is consistent with the length direction of the support block 300. The connecting rod 120 passes through and rotatably connects to the inner wall of the frame 100 and the connecting groove 312 at the end away from the rotating cavity 310.

[0043] Reference Figure 4 and Figure 5A sleeve 420 is connected to one end of the feeding rod 400 along its length. The central axis of the sleeve 420 is collinear with the central axis of the feeding rod 400. The sleeve 420 is rotatably connected in the connecting groove 312 and slidably connected in the connecting groove 312 and the rotating cavity 310 along its length. The sleeve 420 is slidably sleeved on the connecting rod 120, and the central axis of the connecting rod 120 is collinear with the central axis of the sleeve 420. A locking component 600 is connected to the connecting rod 120, and the sleeve 420 is detachably connected to the connecting rod 120 through the locking component 600. The feeding rod 400 is slidably connected in the rotating cavity 310 and the moving port 311 along its length. A mounting plate 350 is connected to one end of the support block 300 along its length. The mounting plate 350 is used to open or close the movable port 311. The mounting plate 350 is embedded in the movable port 311 and is detachably connected to the support block 300 by bolts. The bolts pass through the mounting plate 350 along the length of the support block 300 and are threaded to the frame 100.

[0044] Reference Figure 4 A pull rod 430 is connected to one end of the feeding rod 400 near the moving port 311. The length direction of the pull rod 430 is the same as that of the feeding rod 400. An annular groove 431 is formed at the end of the pull rod 430 away from the feeding rod 400. A rotating hole 351 is formed at the beginning of the mounting plate 350. The length direction of the rotating hole 351 is the same as that of the pull rod 430. The pull rod 430 passes through and is slidably connected in the rotating hole 351 along its length direction.

[0045] Reference Figure 4 and Figure 5 The connecting rod 120 has a mounting groove 121 on its circumference. The length direction of the mounting groove 121 is consistent with the radial direction of the connecting rod 120. The locking assembly 600 includes a first spring 610 and a locking block 620. The length direction of the first spring 610 is consistent with the length direction of the mounting groove 121. One end of the first spring 610 is connected to the inner wall of the mounting groove 121 along its length direction, and the other end of the first spring 610 is connected to the locking block 620. The locking block 620 is slidably connected to the mounting groove 121 along its length direction. The inner wall of the sleeve 420 has a locking groove 421, and the locking block 620 is embedded in the locking groove 421. The locking block 620 has guide surfaces on both sides along the length direction of the feeding rod 400. The guide surfaces are located at the end of the locking block 620 away from the first spring 610 and are inclined to facilitate the locking block 620 to be embedded in or away from the locking groove 421. When disassembling the feeding rod 400, move the feeding rod 400 along its length so that the locking block 620 is embedded in the mounting groove 121. This makes it easier for the sleeve 420 to move away from the connecting groove 312 and for the feeding rod 400 to move away from the rotating cavity 310, thus facilitating the cleaning and replacement of the feeding rod 400.

[0046] The principle of the feeding device for a washing machine according to an embodiment of this application is as follows: During use, the feeding chamber 410 is connected to the storage tank 200. The cleaning agent in the storage tank 200 enters the feeding chamber 410 through the connecting port 210 and the connection port 330. When the feeding chamber 410 is full of cleaning agent, the second motor 110 drives the connecting rod 120 to rotate, causing the feeding rod 400 and the sleeve 420 to rotate, thereby bringing the feeding chamber 410 closer to the discharge port 320. When the opening of the feeding chamber 410 faces... When one side of the water outlet pipe 500 is open, the corresponding nozzle 510 sprays water towards the discharge port 320. When the feeding rod 400 rotates so that the opening of the feeding chamber 410 faces the other side of the water outlet pipe 500, the corresponding nozzle 510 sprays water towards the discharge port 320. This allows the cleaning agent to dissolve in the water and accelerates the discharge of the cleaning agent from the feeding chamber 410. The washing machine is fed through the feeding chamber 410, which facilitates the quantitative addition of cleaning agent into the washing machine, reduces waste of cleaning agent, and improves the cleaning effect.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
