Description

Technical Field

[0001] The present invention relates to the technical field of washing equipment, in particular to a clothing processing device and a drainage component thereof. Background Art

[0002] With the advancement of science and technology, people's living standards are getting higher and higher, and daily housework is gradually being replaced by machines instead of manual labor. As common household appliances in daily life, washing machines, shoe washers and other clothing processing equipment have brought great convenience to people's lives.

[0003] Currently, clothes processing equipment is mainly divided into pulsator-type and drum-type structures. The drum-type structure is increasingly favored by users due to its advantages such as less wear on clothes, saving water and electricity, and high space utilization.

[0004] Drum-type laundry processing equipment typically uses an upper drainage system, using a drain pump to drive the water. Because a drain pump only drives the water flow and lacks a flow cutoff function, the drain pipe is typically raised to a certain height before being lowered. This structure prevents the water from being completely drained.

[0005] Furthermore, at the end of the drain or spin cycle, when the drain pump runs low on water and there's no more water to drive it, the pump mixes with air, causing noticeably louder noise and requiring it to stop. When the pump stops, water in the raised drain pipe, near the pump, flows back into the pump. Depending on the pipe's inner diameter and the height it's lifted, this can leave around 400-600 ml of residual water. This water, which remains at the bottom of the outer tub for extended periods, creates a damp, dark environment inside, breeding bacteria and odors. This is also the root cause of odors when clothes are not removed promptly after washing.

[0006] In addition, some drum-type clothing processing equipment also uses downward drainage to drain water, that is, a drain valve is used to control the on and off of the drain pipe. However, the drain valve only has an opening and closing function and cannot drive the water flow. Therefore, the downward drainage method has a slow drainage speed and cannot meet the user's demand for products in the context of a faster pace of life.

[0007] Therefore, how to drain the residual water in the drain pipe and reduce the noise of the clothing processing equipment while still saving water and electricity and not increasing the washing time is a difficult problem that needs to be solved urgently for the drum-type clothing processing equipment.

[0008] In view of this, the present invention is proposed. Summary of the Invention

[0009] The technical problem to be solved by the present invention is to at least overcome some of the shortcomings of the prior art, and provide a drainage component of a clothing processing device, which adopts the form of combining upper drainage and lower drainage. By arranging a mechanical valve component between the lower drainage pipe and the upper drainage pipe, when the water flow pressure is large, the water flow pressure is used to push the valve core to block the outlet of the guide pipe, so that the water flows out through the upper drainage pipe, and when the water flow pressure is small, the valve core is reset under the action of the reset component, and the outlet of the guide pipe is opened, so that the water flows out through the lower drainage pipe. It can not only achieve the purpose of accelerating the drainage speed and reducing noise, but also utilize the lower drainage pipe to achieve the purpose of draining residual water, and the mechanical valve component does not require electric drive, and will not increase the energy consumption of the clothing processing device.

[0010] To solve the above technical problems, the present invention provides a drainage assembly for a clothes processing device, comprising a drainage pump, a first lower drainage pipe, a second lower drainage pipe, an upper drainage elbow, and a valve assembly;

[0011] The valve assembly includes a valve body provided with a flow guide tube, a valve core provided in the valve body, and a reset assembly connected to the valve core, wherein the valve core divides the inner cavity of the valve body into a water inlet cavity and a water outlet cavity;

[0012] The two ends of the first lower drain pipe are respectively connected to the water outlet of the drain pump and the water inlet chamber, and one end of the second lower drain pipe is connected to the water outlet chamber;

[0013] The two ends of the upper drainage elbow are respectively connected to the water inlet chamber and the water outlet chamber;

[0014] The valve core is configured to utilize water flow pressure to overcome the restoring force of the reset component to block the outlet of the guide pipe, and is reset to between the inlet and outlet of the guide pipe under the driving of the restoring force of the reset component, so that the water inlet chamber and the water outlet chamber are connected via the guide pipe.

[0015] In some embodiments, a mounting hole is provided on the top of the valve body;

[0016] Wherein, the reset component includes:

[0017] a limiting member, one end of which is sealed and fixedly connected to the mounting hole, and the other end of which is suspended in the valve body;

[0018] A return spring has one end connected to the limit member and the other end connected to the valve core.

[0019] In some embodiments, a through hole is provided on the limiting member, and one end of the return spring extends into the through hole and is fixedly connected to the limiting member.

[0020] In some embodiments, the inlet of the flow guide pipe is arranged at the bottom wall of the water inlet cavity, and the outlet of the flow guide pipe is arranged at the bottom wall of the water outlet cavity.

[0021] In some embodiments, the bottom of the limiting member is not lower than the guide tube.

[0022] In some embodiments, the valve core has a water containing cavity, and the opening of the water containing cavity faces the water inlet cavity.

[0023] In some embodiments, the inner peripheral wall of the water containing chamber is a gradually expanding frustum wall from the water inlet chamber to the water outlet chamber, and an opening end of the water containing chamber coincides with an end face of the valve core.

[0024] In some embodiments, the bottom wall of the valve body is tilted downward from the water inlet chamber to the water outlet chamber, and the tilt angle is a first angle;

[0025] Wherein, the cone angle of the inner peripheral wall of the water containing cavity is a second angle, and the second angle is greater than or equal to the first angle.

[0026] In some embodiments, the valve body is provided with a plurality of connection joints respectively connected to the first lower drain pipe, the second lower drain pipe, the upper drain elbow, and the guide pipe.

[0027] The present invention also provides a clothes processing device, comprising a water container and the drainage assembly of the clothes processing device;

[0028] The water container is connected to the water inlet of the drainage pump via a water diversion pipe.

[0029] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0030] (1) The drainage assembly of the clothing processing equipment provided by the present invention adopts the form of combining upper drainage and lower drainage. By arranging a mechanical valve assembly between the lower drainage pipe and the upper drainage pipe, when the water flow pressure is relatively high, the water flow pressure is used to push the valve core to block the outlet of the guide pipe, so that the water flows out through the upper drainage pipe. When the water flow pressure is relatively low, the valve core is reset under the action of the reset assembly, and the outlet of the guide pipe is opened, so that the water flows out through the lower drainage pipe. It can achieve the purpose of accelerating the drainage speed and reducing noise, and can also use the lower drainage pipe to achieve the purpose of draining residual water. In addition, the mechanical valve assembly does not require electric drive and will not increase the energy consumption of the clothing processing equipment.

[0031] (2) The drainage assembly of the clothing processing device provided by the present invention can still drain the water in the outer drum when the water level in the outer drum is low and the drainage pump is turned off. On the one hand, it can alleviate the problem in the prior art that the drainage pump inhales air and makes a loud noise due to the low water level, and it can also avoid frequently starting the drainage pump, thereby reducing the energy consumption of the clothing processing device.

[0032] (3) The drainage assembly of the clothing processing equipment provided by the present invention has a high degree of integration and can be directly modified on existing products, which is easy to implement and reduces costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0048] Figure 1The following is a schematic diagram of the structure of a laundry processing device 10 provided according to an exemplary embodiment of the present invention. The diagram uses a drum washing machine as an example. To clearly illustrate the principles of the present invention, some components unrelated to the present invention, such as the suspension device, counterweight, water inlet assembly, dispenser box, and display device, are not shown and are partially cut away. The laundry processing device 10 may also be a drum washer-dryer, shoe washer, or the like, without limitation to this invention.

[0049] like Figure 1 As shown, the laundry processing device 10 includes a housing 100 and an outer drum 200 and an inner drum 220 arranged inside the housing 100. A laundry inlet and a door 110 for opening and closing the laundry inlet are provided on the front side of the housing 100. The door 110 is provided with an observation window, and a sealing window gasket is also provided between the laundry inlet and the outer drum 200. The inner drum 220 is connected to a drive unit 230 for driving the inner drum 220 to rotate. The outer drum 200 is the water storage drum of the laundry processing device 10. The outer drum 200 is connected to a drainage assembly 300 for draining water from the outer drum 200. The drainage assembly 300 uses a combination of upper drainage and lower drainage to drain water.

[0050] Specifically, the drainage assembly 300 includes a drainage pump 310, a first lower drainage pipe 320, a second lower drainage pipe 330, an upper drainage elbow 340, and a valve assembly 350. The water inlet of the drainage pump 310 is connected to the outer cylinder 200 through the water diversion pipe 210.

[0051] Figure 2 It shows the state of the valve assembly 350 when the water pressure is high or the water flow is fast according to the first exemplary embodiment of the present invention; Figure 3 Schematic diagram showing the state of the valve assembly 350 when the water pressure is low or the water flow is slow according to the first exemplary embodiment of the present invention; Figure 4 FIG. 3 shows a top view of the valve assembly 350 when the water pressure is low or the water flow is slow according to the first exemplary embodiment of the present invention.

[0052] like Figures 2 to 4As shown, the valve assembly 350 includes a valve body 351 provided with a guide tube 354, a valve core 352 provided in the valve body 351, and a reset assembly 353 connected to the valve core 352. The valve core 352 divides the inner cavity of the valve body 351 into a water inlet chamber 3511 and a water outlet chamber 3512. The two ends of the first lower drain pipe 320 are respectively connected to the water outlet of the drain pump 310 and the water inlet chamber 3511, and one end of the second lower drain pipe 330 is connected to the water outlet chamber 3512. The two ends of the upper drain bend pipe 340 are respectively connected to the water inlet chamber 3511 and the water outlet chamber 3512. The valve core 352 is configured to use the impact force of the water flow or the water pressure to overcome the restoring force of the reset assembly 353 to block the outlet of the guide tube 354 when the water flow is fast or the water pressure is high, so that the water flow is accumulated or discharged through the upper drain bend pipe 340 when the drain pump 310 is turned on. Figure 2 Moreover, when the water flow is small and the water pressure disappears, the restoring force of the reset component 353 drives the reset component 353 to reset between the inlet and outlet of the guide pipe 354, so that the water inlet chamber 3511 and the water outlet chamber 3512 are connected via the guide pipe 354, so that the water flow is discharged through the second lower drain pipe 330. Figure 3 and Figure 4 It should be noted that the bent portion of the upper drain elbow 340 should be a certain distance higher than the highest design water level of the clothes processing device 10 to prevent water leakage.

[0053] Specifically, when the laundry processing apparatus 10 is in the initial stage of water inflow, the water pressure in the first lower drain pipe 320 is insufficient to overcome the restoring force of the reset assembly 353 and push the valve core 352 in the valve assembly 350. At this time, the outlet of the flow guide pipe 354 is not blocked by the valve core 352, and a small amount of water will be discharged through the flow guide pipe 354 and the second lower drain pipe 330. However, the diameter of the flow guide pipe 354 is very small, and therefore the amount of water discharged through the flow guide pipe 354 is also very small, and will not substantially affect the time it takes for water to enter the outer drum 200. By way of example, the diameter of the flow guide pipe 354 is approximately one-third of the diameter of the water inlet pipe and approximately one-sixth of the diameter of the first lower drain pipe 320. As can be understood, during the initial water inflow, the amount of water flowing into the outer cylinder 200 through the water inlet pipe is significantly greater than the amount draining through the diversion pipe 354. Therefore, upon entering the outer cylinder 200, the water rapidly converges and enters the water inlet chamber 3511 through the water diversion pipe 210, the drainage pump 310, and the first lower drainage pipe 320. Under the impact of the water flow, the valve core 352 overcomes the restoring force of the reset assembly 353 and moves toward the water outlet chamber 3512, thereby blocking the outlet of the diversion pipe 354 and shutting off the water flow in the diversion pipe 354, causing water to rapidly accumulate in the outer cylinder 200. After water accumulation, the water flow disappears and the water pressure rises. This pressure forces the valve core 353 to maintain its position blocking the outlet of the diversion pipe 354, thereby maintaining continuous water storage without leakage. During the initial period of rising water pressure, even if the valve core 353 does not completely block the outlet of the diversion pipe 354, due to the relatively thin diversion pipe 354, little water leaks out. As the water pressure rises, the valve core 353 completely blocks the outlet of the guide pipe 354. Since the bend of the upper drain elbow 340 is higher than the maximum water level of the laundry processing apparatus 10, the water in the outer tub 200 will not leak out through the upper drain elbow 340 when the drain pump 310 is turned off.

[0054] When the laundry processing apparatus 10 is in the washing or rinsing stage, the water pressure in the first lower drain pipe 320 continuously overcomes the restoring force of the reset assembly 353 , causing the valve core 352 to continuously block the outlet of the guide pipe 354 to prevent water leakage.

[0055] When the clothing processing device 10 is in the early stage of the drainage stage, there is a large amount of water in the outer drum 200, and the drainage pump 310 starts to drain. The water flow pressure in the first lower drainage pipe 320 continues to overcome the restoring force of the reset component 353, so that the valve core 352 continues to block the outlet of the guide pipe 354. At this time, the water flow with a large water pressure will flow from the water inlet chamber 3511 to the water outlet chamber 3512 through the upper drainage bend 340, and then be discharged through the second lower drainage pipe 330.

[0056] When the laundry processing apparatus 10 is in the late stage of the draining phase or the spin phase, there is no water accumulated in the outer drum 200, and the drain pump 310 is turned off, significantly reducing the noise generated by the drain pump 310 during low water flow. Since the water flow is relatively low at this time, the valve core 352 is reset to between the inlet and outlet of the flow guide 354 by the restoring force of the reset assembly 353. Due to the low water pressure at this time, water can only flow through the flow guide 354 from the water inlet chamber 3511 to the water outlet chamber 3512, and then be discharged through the second lower drain pipe 330. Furthermore, the water in the upper drain bend 340 also flows towards the water inlet chamber 3511 under the action of gravity, thus preventing residual water from remaining in the upper drain bend 340.

[0057] In the above scheme, the drainage component 300 of the clothing processing device 10 adopts the form of combining upper drainage and lower drainage. By setting a mechanical valve component 350 between the lower drain pipe and the upper drain pipe, when the water flow is faster or the water pressure is higher, the water flow pressure discharged by the drainage pump 310 is used to push the valve core 352 to block the outlet of the guide pipe 354, so that the water flow is discharged through the upper drain pipe. When the water flow pressure is lower, the valve core 352 is reset under the action of the reset component 353, and the outlet of the guide pipe 354 is opened, so that the water flow is drained through the lower drain pipe. It can not only achieve the purpose of accelerating drainage speed and reducing noise, but also utilize the lower drain pipe to achieve the purpose of draining residual water. The mechanical valve component 350 does not require electric drive and will not increase the energy consumption of the clothing processing device 10.

[0058] It should be noted that during the drainage process, the control unit of the clothing processing device 10 can obtain the water level height through detection elements such as water level sensors. When the water level height is less than a predetermined water level threshold, the control unit can issue a control instruction to control the drainage pump 310 to stop running. The above-mentioned water level threshold can be data obtained by technicians after a large number of experiments and studies, and is stored in the control unit of the clothing processing device 10 before the clothing processing device 10 leaves the factory. As an example, the water level threshold can be set to the height of the water inlet of the drainage pump 310 to prevent the drainage pump 310 from sucking in air. In addition, it is also possible to determine whether to end drainage based on the power change of the drainage motor of the drainage pump 310. For example, when the monitored drainage motor power decreases, it indicates that the water volume is insufficient. Continuing to drain will discharge a mixture of water and air, causing an abnormal increase in noise. At this time, the drainage motor is controlled to stop running, ending drainage. In addition, the drainage pump 310 can adopt a structure commonly used in the field, and the present invention is not limited to this.

[0059] In some embodiments, the valve body 351 is provided with a plurality of connectors that are respectively connected to the first lower drain pipe 320, the second lower drain pipe 330, the upper drain elbow 340, and the flow guide pipe 354. This makes the pipe connections more reliable, improves the integration of the valve assembly 350, and facilitates assembly production.

[0060] Specifically, the valve body 351 is provided with a first connecting joint 3513, a second connecting joint 3514, a third connecting joint 3515, a fourth connecting joint 3516, a fifth connecting joint 3517, and a sixth connecting joint 3518. The first connecting joint 3513 is connected to the first lower drain pipe 320, the second connecting joint 3514 is connected to the second lower drain pipe 330, the third connecting joint 3515 and the fourth connecting joint 3516 are respectively connected to the ends of the upper drain elbow 340, and the fifth connecting joint 3517 and the sixth connecting joint 3518 are respectively connected to the ends of the diversion pipe 354.

[0061] In addition, annular ribs 3519 are provided on the outer walls of the first connecting joint 3513, the second connecting joint 3514, the third connecting joint 3515 and the fourth connecting joint 3516. During installation, after the first connecting joint 3513, the second connecting joint 3514, the third connecting joint 3515 and the fourth connecting joint 3516 are respectively inserted into the corresponding pipe fittings, a pipe clamp is provided on the outer periphery of the annular rib 3519 to facilitate a firm and reliable connection between the two.

[0062] As an example, the main body of the valve body 351 is a transversely arranged pipe fitting with openings at both ends, and the openings at both ends respectively constitute the above-mentioned first connecting joint 3513 and second connecting joint 3514. The upper part is provided with a third connecting joint 3515 and a fourth connecting joint 3516 for installing and fixing the upper drainage bend pipe 340. The fifth connecting joint 3517 and the sixth connecting joint 3518 are provided near the bottom for installing the guide pipe 354.

[0063] In an alternative solution, the valve body 351 is integrally formed with the flow guide tube 354 , and there is no need to additionally provide the fifth connecting joint 3517 and the sixth connecting joint 3518 for connecting to the flow guide tube 354 .

[0064] In some embodiments, the inlet of the guide tube 354 is arranged at the bottom wall of the water inlet chamber 3511, and the outlet of the guide tube 354 is arranged at the bottom wall of the water outlet chamber 3512, so that the water in the valve assembly 350 can be discharged through the guide tube 354 to prevent residual water from remaining in the valve assembly 350 after drainage is completed.

[0065] In some embodiments, the top of the valve body 351 is provided with a mounting hole for mounting a reset assembly 353. The reset assembly 353 includes a stopper 3531 and a reset spring 3532. One end of the stopper 3531 is sealed and fixedly connected to the mounting hole, while the other end is suspended within the valve body 351. One end of the reset spring 3532 is connected to the stopper 3531, while the other end is connected to the valve core 352. Optionally, the bottom of the stopper 3531 is not lower than the guide tube 354 to prevent the stopper 3531 from blocking the flow of water from the water outlet chamber 3512 within the valve body 351.

[0066] As an example, one end of the stopper 3531 is threadedly mounted to the mounting hole of the valve body 351. During assembly, the stopper 3531 can be installed first, and after adjusting the angle, the return spring 3532 can be secured, and finally the valve core 352 can be installed. Optionally, the return spring 3532 can be fixedly connected to the valve core 352, for example, by providing a mounting groove 3521 on the side of the valve core 352 facing the return spring 3532, and providing a threaded structure within the mounting groove 3521, and the return spring 3532 can be screwed into the mounting groove 3521 to secure it.

[0067] In some embodiments, a through hole is provided on the limiting member 3531 , and one end of the return spring 3532 extends into the through hole and is fixedly connected to the limiting member 3531 .

[0068] As an example, the through hole is a stepped hole 35311. After one end of the reset spring 3532 extends into the small aperture section of the stepped hole 35311, it is connected to the blocking piece 35312 located in the large aperture section of the stepped hole 35311. The blocking piece 35312 is used to realize the fixed connection between the reset spring 3532 and the limit piece 3531.

[0069] In the above solution, extending the return spring 3532 into the stopper 3531 can reduce the length required for the return spring 3532 to expand and contract within the valve body 351, thereby reducing the overall size of the valve assembly 350 and preventing the valve assembly 350 from occupying a large space within the housing 100 of the laundry processing device 10. This allows for direct retrofitting of existing machines, reducing costs. Furthermore, extending the return spring 3532 into the stopper 3531 can prevent the return spring 3532 from bending under pressure and losing its restoring force.

[0070] In some embodiments, as Figure 5As shown, the valve core 352 has a water receiving chamber 3522, the opening of which faces the water inlet chamber 3511. The bottom wall of the water receiving chamber 3522 is connected to the reset assembly 353. When water flows toward the valve core 352, it can enter the water receiving chamber 3522 of the valve core 352, and the water pressure acts on the bottom wall of the water receiving chamber 3522.

[0071] As an example, the valve core 352 can be a cylindrical structure with one end closed and the other open. The outer diameter of the valve core 352 is consistent with the inner diameter of the valve body 351, and the two are clearance-matched. Furthermore, the aforementioned mounting groove 3521 is provided at the center of the end of the valve core 352 opposite the open side for mounting and fixing the return spring 3532.

[0072] In the above solution, setting the valve core 352 as a cylindrical structure can effectively increase the size of the valve core 352 in the expansion and contraction direction of the return spring 3532, so that it can effectively block the outlet of the guide tube 354 without increasing the weight of the valve core 352.

[0073] Optionally, the inner peripheral wall of the water containing cavity 3522 is a gradually expanding frustum wall 3523 from the water inlet cavity 3511 toward the water outlet cavity 3512 , and the opening end of the water containing cavity 3522 coincides with the end face of the valve core 352 . Figure 5 It can be seen in the cross-sectional view that the inner peripheral wall of the water holding chamber 3522 is a downward slope from the water outlet chamber 3512 toward the water inlet chamber 3511 , which can prevent residual water from remaining in the water holding chamber 3522 of the valve core 352 at the end of drainage.

[0074] In some embodiments, the bottom wall of the valve body 351 is tilted downward from the water inlet chamber 3511 to the water outlet chamber 3512, and the tilt angle is a first angle α. Figure 6 As shown, the valve body 351 of the pipe structure is tilted. Figure 6 As can be seen in the cross-sectional view, the bottom wall of the valve body 351 is a downward slope from the water inlet chamber 3511 to the water outlet chamber 3512, which can prevent residual water from remaining in the valve body 351 when drainage is completed.

[0075] It should be noted that the cone angle of the gradually expanding conical wall 3523 of the water containing chamber is a second angle β, which is greater than or equal to the first angle α to prevent the water in the water containing chamber 3522 of the valve core 352 from being unable to be naturally discharged after drainage is completed.
