Description

Technical Field

[0001] This invention relates to the field of garment care machine technology, specifically a water circulation system for garment care machines. Background Technology

[0002] The working principle of a garment care machine is as follows: steam is continuously introduced into a sealed care space through a steam generator. The steam fully contacts and soaks the garments in the care space, achieving the desired care effect. Because garment care machines use a large amount of water during the entire process, most manufacturers recycle the water to conserve water.

[0003] For example, Chinese Patent Publication No. CN217103293U discloses a wastewater filtration device for a garment care machine. By setting up a filtration device between a wastewater tank and a clean water tank, the wastewater generated by the garment care machine during operation flows from the wastewater tank into the clean water tank for purification, thus realizing the recycling of wastewater.

[0004] For example, Chinese Patent Publication No. CN209907070U discloses a self-cleaning water device for a clothing care machine, which achieves water conservation by setting a filter component between the water tank and the water pump.

[0005] However, in actual use, the above-mentioned filter device still has the following drawbacks: Since the wastewater of the nursing machine is often mixed with a large amount of lint, fuzz, etc., the filter device is extremely easy to be clogged. In addition to affecting the steam output, it also requires frequent and cumbersome disassembly and replacement, which brings great inconvenience to users. Summary of the Invention

[0006] The purpose of this invention is to provide a water circulation system for a garment care machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A water circulation system for a garment care machine, comprising

[0009] A water tank is located at the bottom of the tank body. The water tank is connected to the inlet of the water pump through an inlet pipe. The outlet of the water pump is connected to the inlet of the steam generator.

[0010] The air duct is built into the back panel of the box. One end of the air duct is connected to the air outlet of the steam generator, and the other end of the air duct extends to the top of the box and enters the nursing space to form an air outlet.

[0011] The return air vent is located at the bottom of the care space. The return air vent is connected to the return water pipe at the bottom of the box. The lower end of the return water pipe faces the filter device located at the top of the water tank, so that the care water in the care space is filtered by the filter device and then enters the water tank again.

[0012] The filtering device includes a drive roller, a driven roller, and a guide wheel mounted on a mounting frame, forming a rectangular frame. A filter screen is arranged around the drive roller, driven roller, and guide wheel to form a reciprocating conveyor belt. A cleaning roller is arranged inside the rectangular frame and is coaxially mounted on a second rotating shaft. The second rotating shaft is connected to the cleaning roller via a spline, so that the cleaning roller can also move axially during rotation. A motor for driving the rotation is connected to one end of the second rotating shaft. The cleaning roller is provided with bristles that contact the filter screen. A rejection roller is provided outside the cleaning roller, and a rejection groove is provided on the rejection roller for the bristles to pass through. The rejection roller is eccentrically arranged with the cleaning roller so that the distance the bristles travel through the rejection groove is the longest at the highest position and the shortest at the lowest position.

[0013] Preferably, one end of the cleaning roller and the rejection roller is rotatably mounted on the drive sleeve. The drive sleeve is sleeved on one end of the second rotating shaft. A first drive wheel that rotates synchronously with the second rotating shaft is provided on the end of the second rotating shaft near the drive sleeve. The first drive wheel meshes with a second drive wheel on the fixed sleeve. One end of the second drive wheel is connected to a connecting rod, and the other end of the connecting rod is connected to the drive sleeve, so as to drive the cleaning roller and the rejection roller to reciprocate along the axial direction of the second rotating shaft.

[0014] Preferably, it also includes a dust collection roller detachably mounted on the housing, the opening at the top of the dust collection roller corresponding to the bottom of the rejection roller, a cleaning shaft rotatably mounted inside the dust collection roller via a third rotating shaft, and a handle mounted on one end of the third rotating shaft extending to the outside of the dust collection roller.

[0015] Preferably, the cleaning shaft is eccentrically positioned relative to the third rotating shaft.

[0016] Preferably, the dust collection roller is made of sponge material.

[0017] Preferably, both the driving roller and the driven roller include a first rotating shaft, and a first driving wheel is provided at the end of the first rotating shaft, and the diameter of the first driving wheel is larger than the diameter of the first rotating shaft.

[0018] Preferably, the filter screen is provided with drive belts at both ends that cooperate with the first drive wheel, and a side panel is provided on the side of the drive belt away from the filter screen.

[0019] Preferably, the first drive wheel and drive belt are a synchronized pulley and a synchronized belt that cooperate with each other.

[0020] Preferably, the rejection groove is a curved groove.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] This invention features a filter screen with a conveyor belt structure installed between the return water inlet and the water tank. Compared to existing filters with fixed shapes and states, this invention's filter screen offers more efficient filtration, and its reciprocating motion prevents clogging, avoiding tedious cleaning and replacement. Simultaneously, the cleaning roller, aided by brush bristles, cleans and removes impurities from the reciprocating filter screen. Furthermore, the removal roller allows lint, hair, and other foreign objects to directly enter the dust collection roller for collection, ensuring filter screen cleanliness and thus guaranteeing filtration effectiveness. More importantly, the drive device, consisting of a first drive wheel, a second drive wheel, and connecting rods, enables the cleaning roller and brush bristles to rotate while also exhibiting axial movement, further enhancing the cleaning effect on the filter screen.

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

[0031] Please see Figure 1-6 The present invention provides a technical solution:

[0032] A water circulation system for a garment care machine, comprising

[0033] Water tank 2, which is detachably installed at the bottom of the box body 1, is used to hold clean water for generating steam. Water tank 2 is connected to the inlet of water pump 4 through water inlet pipe 3, and the outlet of water pump 4 is connected to the inlet of steam generator 5.

[0034] The air duct 6 is built into the back panel of the housing 1. One end of the air duct 6 is connected to the air outlet of the steam generator 5, and the other end of the air duct 6 extends to the top of the housing 1 and enters the nursing space 7 to form an air outlet 8.

[0035] The return air vent 9 is located at the bottom of the care space 7. The return air vent 9 is connected to the return water pipe 10 at the bottom of the box 1. The lower end of the return water pipe 10 faces the filter device 11 located at the top of the water tank 2, so that the care water (water formed after steam condensation) in the care space 7 is filtered by the filter device 11 and then enters the water tank 2 again.

[0036] When the garment care machine is used to care for garments, the water pump 4 draws the clean water in the water tank 2 into the steam generator 5 to generate steam. The steam is "blown" into the care space 7 through the air outlet 8 under the action of the air duct 6, so that it can fully contact and soak the garments that need to be cared for, thereby achieving the care effects of wrinkle removal, deodorization and shaping. The steam cools down to form condensate, which flows back into the water tank 2 after being filtered by the filter device 11 through the return air vent 9 at the bottom of the box 1 and the return water pipe 10. This realizes the reuse of the care water and achieves the purpose of water conservation.

[0037] The filter device 11 includes a drive roller 12, a driven roller 13, and a guide wheel 15 mounted on a mounting frame 14, forming a rectangular frame that can better accommodate the cleaning device in its center. In this embodiment, both the drive roller 12 and the driven roller 13 include a first rotating shaft 16. A first drive wheel 17 is provided at the end of the first rotating shaft 16, and the diameter of the first drive wheel 17 is larger than the diameter of the first rotating shaft 16. This arrangement is intended to keep the first rotating shaft 16 away from the filter screen 18, preventing the first rotating shaft 16 from pressing against the filter screen 18. This causes foreign objects to adhere tightly to the surface of the filter screen 18, making it difficult to clean; the first drive wheel 17 on the drive roller 12 is connected to the motor drive; the filter screen 18 is arranged around the drive roller 12, the driven roller 13 and the guide wheel 15 to form a reciprocating conveyor belt. By setting the filter screen 18 with a conveyor belt structure, compared with the filter screen with a fixed shape and fixed state in the prior art, the filter screen 18 of the present invention has a highly efficient filtration effect, and the cyclical motion makes it less prone to clogging, avoiding tedious cleaning and replacement, and bringing great convenience to users;

[0038] A cleaning roller 21 is housed inside a rectangular frame. The cleaning roller 21 is coaxially mounted on a second rotating shaft 22, which is connected to the cleaning roller 21 via a spline. This allows the cleaning roller 21 to move axially during rotation. The advantage of this arrangement is that the bristles 25 on the cleaning roller 21 and the filter screen 18 have both radial and axial relative movement, increasing the contact area between the bristles 25 and the filter screen 18, thus achieving more efficient cleaning. One end of the second rotating shaft 22 is connected to a motor 24 via a coupling to drive its rotation. The bristles 25 on the cleaning roller 21, which contact the filter screen 18, effectively remove lint, thread ends, and other foreign matter adhering to the surface of the filter screen 18 through continuous rotation. A rejection roller 26 is provided on the outside of the roller 21. The rejection roller 26 has rejection grooves 27 for the brush bristles 25 to pass through. The rejection roller 26 is eccentrically arranged with the cleaning roller 21 so that the distance the brush bristles 25 travel through the rejection grooves 27 is the longest at the highest position and the shortest at the lowest position. The purpose of this arrangement is that when the brush bristles 25 rotate to the highest position, they can fully contact the upper filter screen 18 to clean the foreign objects on the filter screen 18. When the brush bristles 25 rotate to the lowest position, they can "retract" into the rejection roller 26. It is equivalent to the rejection roller 26 "combing" the brush bristles 25 through the lower rejection grooves 27, thereby transferring the lint and thread ends on the brush bristles to the outside of the rejection roller 26, achieving the purpose of cleaning the foreign objects on the brush bristles 25.

[0039] To allow the brush bristles 25 and the filter screen 18 to have axial relative movement, one end of the cleaning roller 21 and the rejection roller 26 are rotatably mounted on the drive sleeve 23. The drive sleeve 23 is sleeved on one end of the second rotating shaft 22. The drive sleeve 23 does not rotate synchronously with the cleaning roller 21, the rejection roller 26 and the second rotating shaft 22. The drive sleeve 23 can move axially along the second rotating shaft 22 under the action of the drive device, thereby linking the cleaning roller 21 and the rejection roller 26 to produce lateral axial movement. A first drive wheel 33 is provided on the end of the second rotating shaft 22 near the drive sleeve 23 and rotates synchronously with it. The first drive wheel 33 meshes with the second drive wheel 34 on the fixed sleeve 32. The first drive wheel 33 and the second drive wheel 34 are bevel gear structures that mesh with each other. The second drive wheel 34 is connected to one end of the connecting rod 35, and the other end of the connecting rod 35 is connected to the drive sleeve 23 to drive the cleaning roller 21 and the rejection roller 26 to reciprocate axially along the second rotating shaft 22, so that the brush bristles 25 can clean the filter screen 18 more thoroughly.

[0040] It also includes a detachable dust collection roller 28 mounted on the housing 1. The opening at the top of the dust collection roller 28 corresponds to the bottom of the rejection roller 26, allowing the foreign objects that are "sweeped out" to be directly collected into the dust collection roller 28. At the same time, the detachable design of the dust collection roller 28 makes it convenient for users to clean it regularly. Inside the dust collection roller 28, a cleaning shaft 29 is rotatably mounted via a third rotating shaft 30. The cleaning shaft 29 is made of sponge material and is eccentrically mounted to the third rotating shaft 30. A handle 31 is mounted on one end of the third rotating shaft 30 that extends to the outside of the dust collection roller 28. The eccentrically mounted cleaning shaft 29 provides a dust collection space at the top of the dust collection roller 28, which facilitates the collection of foreign objects. At the same time, by rotating the handle 31, the bottom of the cleaning shaft 29 can contact the bottom of the rejection roller 26, thereby effectively cleaning the foreign objects adhering to the bottom of the rejection roller 26 (because the foreign objects become wet during the filtration process, they are easy to adhere to the bottom of the rejection roller 26, and the cleaning shaft 29 made of sponge material has a better cleaning effect).

[0041] To prevent slippage of the first drive wheel 17 during driving, drive belts 19 that cooperate with the first drive wheel 17 are provided at both ends of the filter screen 18. In the technical solution of this embodiment, the first drive wheel 17 and the drive belt 19 adopt a synchronous pulley and a synchronous belt that cooperate with each other. A side wall 20 is provided on the side of the drive belt 19 away from the filter screen 18. Since the care water flows into the filter screen 18, it is easy to overflow from both sides of the filter screen 18. Therefore, by providing side walls 20 on both sides of the filter screen 18, the care water can be effectively "enclosed", so that the care water is not easy to flow out from the side and can only pass through the filter screen 18, thereby improving the filtration effect.

[0042] The removal groove 27 is curved. The purpose of this design is that when the bristles 25 pass through the removal groove 27, the removal groove 27 can have additional left and right "swinging" to better remove foreign objects adhering to the filter screen 18.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
