Description

Technical Field

[0001] This invention belongs to the field of washing technology, and specifically relates to a drainage control method for a washing device. Background Technology

[0002] In daily life, fully automatic washing machines have brought increasing convenience and become an indispensable household appliance. There are two common types of washing machines today: top-loading (pulsator) washing machines and front-loading (drum) washing machines. Top-loading washing machines have a pulsator structure at the bottom of the inner drum. During the washing process, the pulsator rotates in both directions, creating vortices in the water flow. This tumbling of the clothes with the water flow generates friction, achieving the washing effect. Front-loading washing machines, on the other hand, use a motor to rotate the drum. The clothes are repeatedly lifted to higher positions and then tumbled down within the drum, undergoing multiple reciprocating motions to achieve the washing effect.

[0003] However, existing top-loading washing machines have an impeller structure at the bottom of the inner drum. During the washing process, the impeller drives the clothes to rotate back and forth in both directions. This reciprocating rotation makes the clothes easily tangled, requiring manual separation after washing and often causing severe wear and tear. Front-loading washing machines, on the other hand, are relatively less effective at washing clothes.

[0004] Chinese Patent 201822244328.4 discloses a clothing rubbing device that simulates the rubbing method of hand washing. A flexible washing bag, under compression, rotates to achieve rubbing. By changing the direction and speed of rotation of the flexible washing bag, various rubbing methods can be achieved. This allows the clothes inside the flexible washing bag to be rubbed and cleaned during its reciprocating rotation, minimizing damage to the clothes and achieving a good cleaning effect. However, this washing method still differs significantly from the actual rubbing method of hand washing, thus leaving room for improvement in simulating hand washing and achieving better cleaning results. Furthermore, the drainage effect after washing is not ideal.

[0005] Accordingly, there is a need in the art for a new drainage control method for washing devices to solve the aforementioned problems existing in the prior art. Summary of the Invention

[0042] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although the specification describes the kneading drive unit as an electric push rod or linear motor, the present invention can obviously employ other similar means, such as a cylinder, as long as the kneading drive unit can drive the kneading part to cause the flexible washing tub to deform.

[0043] It should be noted that in the description of this invention, terms such as "vertical," "horizontal," "inner," and "outer," indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, terms such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," "equipped," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium, etc. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0045] To address the issues that existing simulated hand-washing methods still differ from actual hand-washing and result in uneven rubbing and washing of clothes, this invention provides a drainage control method for a washing device. This drainage control method relies on a special washing device. Therefore, to more clearly explain the drainage control method, it is necessary to first elaborate on the washing device involved in this invention.

[0046] like Figure 1 As shown, the washing device involved in the drainage control method of the present invention includes a fixedly installed flexible washing tub 1 (which can be a rubber tub) and a kneading assembly 2 disposed outside the flexible washing tub 1. The kneading assembly 2 includes a kneading part 21 and a kneading drive part 22. The kneading part 21 is plate-shaped and can be configured to fit against the outer surface of the flexible washing tub 1. The output end of the kneading drive part 22 is drivenly connected to the kneading part 21, and the kneading part 21 is connected to the flexible washing tub 1. Figure 7 As shown, a kneading groove 112 is provided on the outer surface of the flexible washing tub 1. Figure 3AAs shown, the kneading section 21 is provided with kneading protrusions 212, which enter the kneading groove 112, and can also... Figure 1 and Figure 7 As shown, a kneading block 113 is provided on the outer surface of the flexible washing tub 1, and as... Figure 1 and Figure 2 As shown, the kneading part 21 is provided with a kneading hole 211, and the kneading block 113 is engaged with the kneading hole 211; under the drive of the kneading drive part 22, the kneading part 21 drives the flexible washing tub 1 to perform deformation movement.

[0047] like Figure 1 , 2 As shown in Figure 6, the washing device also includes a squeezing assembly 3 located outside the flexible washing tub 1. The squeezing assembly 3 includes a squeezing part 31 and a squeezing drive part 32. The squeezing part 31 is generally plate-shaped with flanges. The output end of the squeezing drive part 32 is driven to the squeezing part 31. The squeezing part 31 is connected to the kneading assembly 2. The squeezing drive part 32 drives the squeezing part 31 to move the kneading assembly 2 closer to or away from the flexible washing tub 1. A pressure sensor (not shown in the figure) is also provided on the kneading part 21. By setting the squeezing assembly 3, the squeezing force of the kneading assembly 2 on the flexible washing tub 1 can be flexibly adjusted according to the actual usage, and the magnitude of the squeezing force can be fed back by the pressure sensor. For example, depending on the amount of clothes in the flexible washing tub 1, different levels of kneading and washing can be achieved by adjusting the distance between the kneading assembly 2 and the flexible washing tub 1, ensuring that the flexible washing tub 1 can fully contact the clothes.

[0048] like Figure 1 , 2 As shown in Figure 6, the washing device includes a squeezing base 33 and a squeezing drive unit 32, which includes a squeezing motor 321 and a squeezing lead screw 322. The squeezing lead screw 322 is a lead screw with a bidirectional thread. The output end of the squeezing motor 321 is drivenly connected to the squeezing lead screw 322. The squeezing lead screw 322 is rotatable but not axially movable on the squeezing base 33. The squeezing part 31 is threadedly driven connected to the squeezing lead screw 322. To improve the stability of the movement of the squeezing part 31, a squeezing guide rail 323 can also be provided on the squeezing base 33, and the squeezing part 31 is sleeved on the squeezing guide rail 323. The squeezing part 31 is connected to the kneading assembly 2. The direction in which the squeezing drive unit 32 drives the squeezing part 31 to move is perpendicular to the direction in which the kneading drive unit 22 drives the kneading part 21 to move.

[0049] like Figure 1 , 11As shown in Figure -13, the flexible washing tub 1 is further provided with an oscillating part 4 on its exterior. The output end of the oscillating part 4 is connected to the bottom end of the flexible washing tub 1. Under the action of the oscillating part 4, the bottom end of the flexible washing tub 1 oscillates up and down in the vertical direction. The oscillating part 4 includes an oscillating motor 41, an oscillating transfer component 43, and an oscillating head 42. One end of the oscillating head 42 abuts against the bottom end of the flexible washing tub 1, and the other end of the oscillating head 42 is connected to one end of the oscillating transfer component 43. The other end of the oscillating transfer component 43 is drivenly connected to the output end of the oscillating motor 41. The vibrating transfer component 43 has a vibrating protrusion 44 at one end connected to the vibrating head 42, and a vibrating groove 45 at the other end connected to the vibrating transfer component 43. The vibrating motor 41 and the vibrating transfer component 43 are fixedly arranged in the vertical direction. Driven by the vibrating motor 41, the vibrating transfer component 43 rotates. As the vibrating protrusion 44 enters and leaves the vibrating groove 45, the vibrating head 42 periodically moves away from and towards the vibrating transfer component 43, causing the bottom of the flexible washing tub 1 to periodically vibrate up and down. To prevent the vibrating transfer component 43 from detaching from the vibrating head 42 during the rotation of the vibrating transfer component 43 and the periodic movement of the vibrating head 42 away from and towards the vibrating transfer component 43, the vibrating head 42 can be rotatably fitted onto the vibrating transfer component 43.

[0050] like Figure 1 , Figure 7-9 As shown, the flexible washing tub 1 includes an outer tub 11 and an inner tub 12 disposed inside the outer tub 11. The outer tub 11 is fixedly installed and connected to the kneading part 21, while the inner tub 12 is detachably and fixedly connected to the outer tub 11. During use, the inner tub 12 can be removed for cleaning, and multiple tubs can be installed in one machine, avoiding potential cross-contamination and improving hygiene. Figure 9 As shown, the inner side of the outer tub 11 is provided with a transmission protrusion 111, and the outer side of the inner tub 12 is provided with a transmission groove 121. The transmission protrusion 111 enters the transmission groove 121. The transmission protrusion 111 and the transmission groove 121 are used to transmit the force applied by the kneading drive unit 22 through the outer tub 11 to the inner tub 12, thereby improving the kneading and washing effect. The inner side of the inner tub 12 is fixedly provided with a washing protrusion 122, which can further enhance the kneading and washing effect on the washing load inside the inner tub 12 during washing. The flexible washing tub 1 is also provided with an exhaust hole (not shown in the figure). Figure 14 As shown, the flexible washing tub 1 is also provided with a drainage section 5, which includes a drain pipe 51 and a drain pump 52. The drain pipe 51 is connected to the interior of the flexible washing tub 1, i.e., the inner tub 12.

[0051] like Figure 1 , 4As shown in Figure -5, there are two kneading sections 21, located on opposite sides of the flexible washing tub 1. The kneading drive section 22 includes two kneading screws 222 and a kneading motor 221. The output end of the kneading motor 221 is drivenly connected to either of the kneading screws 222. The two kneading screws 222 are respectively located on both sides of the flexible washing tub 1, and each kneading screw 222 is drivenly connected to the adjacent kneading section 21. The kneading screws 222 are rotatable but not axially movable on the flanged portion of the extrusion section 31. To improve the stability of the movement of the kneading section 21, a corresponding kneading guide rail 224 can be provided. The kneading guide rail 224 is fixedly installed on the flanged portion of the extrusion section 31, and the kneading section 21 is sleeved on the kneading screw 222 and the kneading guide rail 224. The kneading screw 222 is threadedly drivenly connected to the kneading section 21. The kneading drive unit 22 also includes a transmission connection part 223, which is a belt. The transmission connection part 223 is drivenly connected to two kneading screws 222 respectively. In this embodiment, two kneading screws 222 are controlled by one kneading motor 221, which facilitates control, improves the synchronous driving effect of the two kneading screws 222, and reduces costs.

[0052] The advantages of the above-described configuration are as follows: Existing pulsator washing machines have a pulsator structure at the bottom of the inner tub. During the washing process, the pulsator drives the clothes to rotate in both directions, which makes the clothes prone to tangling and causing severe wear. In this embodiment, because it is a non-rotating washing method, tangling is less likely. Compared to the washing methods in the prior art, this embodiment is more similar to hand washing and rubbing, resulting in a higher washing efficiency and less damage to clothes. Furthermore, this embodiment also includes a vibration section 4, which periodically vibrates the bottom of the flexible washing tub 1, causing the clothes inside to tumble and thus enabling more thorough and even washing, significantly improving the washing effect.

[0053] The following is a brief description of how to use this embodiment:

[0054] After clothes are placed into the flexible washing tub 1, the squeezing component 3 first moves the two kneading parts 21 towards the center, ensuring full contact between the flexible washing tub 1 and the clothes, and the displacement is determined by a pressure sensor. Then, the reciprocating motion of the two kneading parts 21 achieves a washing method similar to repeated hand washing. The periodic up-and-down oscillation of the bottom of the flexible washing tub 1 by the vibrating part 4 changes the position of the clothes inside, effectively washing different parts of the garments.

[0055] It should be noted that the above embodiments are merely used to illustrate the principle of the washing device of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principle of the present invention, those skilled in the art can adjust the above structure so that the present invention can be applied to more specific application scenarios. These adjustments do not depart from the principle of the present invention and therefore fall within the scope of protection of the present invention.

[0056] For example, in an alternative embodiment, a pressure sensor (not shown) may also be provided on the extrusion section 31.

[0057] For example, in another alternative embodiment, the extrusion drive 32 may also be an electric push rod (not shown) or a linear motor (not shown).

[0058] For example, in another alternative embodiment, the kneading drive unit 22 may also be an electric push rod (not shown) or a linear motor (not shown).

[0059] For example, in another alternative embodiment, the oscillating part 4 is an electric actuator or a linear motor (not shown in the figure).

[0060] For example, in another alternative embodiment, the kneading part 21 can also be configured as a straight plate, and correspondingly, the kneading block 113 and the kneading hole 211 are not provided, such as... Figure 10 As shown.

[0061] For example, in another alternative embodiment, the kneading part 21 may include a plate and a self-rotating roller disposed on the plate, the roller entering a kneading groove disposed on a flexible washing tub (not shown in the figure).

[0062] For example, in another alternative embodiment, the end of the oscillating transducer 43 connected to the oscillating head 42 may be provided with an oscillating groove 45, and the other end of the oscillating head 42 connected to the oscillating transducer 43 may be provided with an oscillating protrusion 44 (not shown in the figure).

[0063] For example, in another alternative embodiment, the kneading drive unit 22 may also include two kneading motors, which are located on both sides of the flexible washing tub 1, and the output of each kneading motor is drivenly connected to the adjacent kneading unit 21 (not shown in the figure).

[0064] For example, in another alternative embodiment, the transmission connection 223 can also be a chain, and each kneading screw 222 has a connecting gear at one end near the transmission connection 223, and the chain meshes with the connecting gear (not shown in the figure).

[0065] For example, in another alternative implementation, such as Figure 3BAs shown, each kneading screw 222 may also have a first bevel gear 2221 at one end near the transmission connection part 223, and a second bevel gear 2231 at both ends of the transmission connection part 223, with the first bevel gear 2221 meshing with the second bevel gear 2231.

[0066] For example, in another alternative embodiment, the squeezing component 3 specifically for squeezing can be omitted, and the washing effect can be achieved by manually adjusting the distance between the two kneading parts 21. In this case, the washing device includes a kneading base (not shown in the figure), and the kneading drive unit 22 includes a kneading motor 221 and a kneading screw 222. The kneading screw 222 is rotatable but not axially movable on the kneading base. The output end of the kneading motor 221 is drivenly connected to the kneading screw 222. The kneading part 21 is sleeved on the kneading screw 222, and the kneading screw 222 is threadedly drivenly connected to the kneading part 21 (not shown in the figure).

[0067] For example, in another alternative embodiment, a transmission groove may be provided on the inner side of the outer barrel 11, and a transmission protrusion may be provided on the outer side of the inner barrel 12.

[0068] For example, in another alternative embodiment, a kneading groove 112 may be provided on the outer surface of the flexible washing tub 1, the kneading part 21 may be provided with the kneading groove 112, and a kneading hole 211 may be provided on the outer surface of the flexible washing tub 1, and the kneading part 21 may be provided with a kneading block 113 (not shown in the figure).

[0069] For example, in another alternative embodiment, the flexible washing tub 1 can also be configured as having no inner tub and outer tub, in which case a protrusion (not shown in the figure) is fixedly provided on the inner wall of the flexible washing tub 1.

[0070] The specific structure of the washing device of the present invention has been described above. The drainage control method of the present invention is designed based on the above scheme or its simple modifications. Next, the first embodiment of the drainage control method of the washing device of the present invention will be described. Figure 15 As shown, the drainage control method for the washing device includes the following steps:

[0071] S1. Control the vent to close.

[0072] S2. Control the extrusion section to extrude to the set position.

[0073] To prevent water from splashing or overflowing during spin-drying, the flexible washing tub is usually sealed. Therefore, in this embodiment, the vent is closed. Furthermore, the vent is controlled to be closed first, ensuring that water cannot exit from any part of the tub except the drain hole, creating a sealed space that facilitates water ejection after squeezing. The squeezing position can be determined by a pressure sensor; any position that allows the flexible washing tub to fully contact the clothes inside is acceptable. Alternatively, the squeezing unit can be controlled to reciprocate, squeezing the flexible washing tub to achieve a certain degree of dehydration.

[0074] S31. Control the kneading section to knead the flexible washing tub while simultaneously controlling the vibration section to vibrate the flexible washing tub.

[0075] S4. Control the exhaust port to open.

[0076] During the drainage process, the continuous operation of the drain pump will cause the pressure inside the flexible washing tub to decrease until it becomes negative. At this point, with the vent closed, it is no longer possible to generate significant pressure through kneading and squeezing. Furthermore, as the drain pump continues to operate, the negative pressure will increase, which will actually affect the operation of the drain pump and hinder drainage. Therefore, opening the vent again after kneading and shaking can prevent the generation of negative pressure.

[0077] S5. Control the drainage section to drain the water from the flexible washing tub.

[0078] In this embodiment, the kneading section mimics the hand-washing method to knead and drain the clothes inside the flexible washing tub. Simultaneously, the vibration section adjusts the position of the clothes, ensuring that different parts of the clothes receive more thorough kneading and effectively improving drainage. After kneading, the remaining water is drained through the drain section, achieving the purpose of dehydration.

[0079] Next, a second embodiment of the control method for the washing apparatus of the present invention will be described. For example... Figure 16 As shown, the control method for the washing device includes the following steps:

[0080] S1. Control the vent to close.

[0081] S2. Control the extrusion section to extrude to the set position.

[0082] The principles and functions of the above two steps are the same as those in the first embodiment, and will not be repeated here.

[0083] S3. Control the kneading section to knead the flexible washing tub and control the shaking section to shake the flexible washing tub alternately.

[0084] S4. Control the exhaust port to open.

[0085] S5. Control the drainage section to drain the water from the flexible washing tub.

[0086] The difference between the second embodiment and the first embodiment is that the rubbing section rubs and drains the clothes inside the flexible washing tub in a manner similar to hand-rubbing. After rubbing for a certain period of time, the rubbing is stopped, the squeezing section relaxes its pressure on the flexible washing tub, and the vibration section effectively adjusts the position of the clothes. Then, the squeezing section squeezes again and the rubbing section rubs, thus separating the rubbing and vibration steps. This allows the rubbed clothes to be shaken apart, and then the rubbing and shaking continue, repeating the cycle. This is closer to the hand-wringing method, and the effect is faster and better than the first embodiment.

[0087] The above embodiments are merely used to illustrate the principle of the drainage method of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principle of the present invention, those skilled in the art can adjust the above methods so that the present invention can be applied to more specific application scenarios.

[0088] For example, in an alternative implementation, in the first embodiment of the drainage method, step S31 can be performed simultaneously with step S5, that is, while controlling the kneading part to knead the flexible washing tub, the shaking part is controlled to shake the flexible washing tub, and at the same time, the drainage part is controlled to drain the water in the flexible washing tub. Accordingly, when step S31 and step S5 are performed simultaneously, the vent can be opened.

[0089] For example, in another alternative implementation, in the second embodiment of the drainage method, step S32 can also be performed simultaneously with step S5, that is, the kneading part is controlled to knead the flexible washing tub and the oscillating part is controlled to oscillate the flexible washing tub alternately, and the drainage part is controlled to drain the water in the flexible washing tub at the same time. Accordingly, the vent can be opened when step S32 and step S5 are performed simultaneously.

[0090] In summary, the washing device of the present invention can achieve a good rubbing and washing effect during washing, and after washing, the drainage control method of the present invention can effectively remove water from the clothes and improve the drainage effect of the flexible washing tub by controlling the squeezing part to squeeze the clothes and the rubbing part to rub the clothes.

[0091] Those skilled in the art will understand that the above-described washing apparatus also includes other known structures, such as processors, controllers, and memories. These memories include, but are not limited to, random access memory (RAM), flash memory, read-only memory (ROM), programmable read-only memory (PROM), volatile memory, non-volatile memory, serial memory, parallel memory, or registers. Processors include, but are not limited to, CPLD / FPGA, DSP, ARM processors, and MIPS processors. To avoid unnecessarily obscuring the embodiments of the present invention, these known structures are not shown in the accompanying drawings.

[0092] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
