Description

Technical Field

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

[0002] In today's daily life, with the continuous development and progress of society, people pay more attention to their hygiene. Correspondingly, people wash their clothes more frequently, but the experience of hand washing is not ideal. Therefore, the emergence of fully automatic washing machines has liberated people from the labor of manual laundry and has become an indispensable household appliance. Currently, there are two common types of washing equipment: top-loading washing machines and front-loading 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 of water flow with different directions. This tumbling of the clothes with the water flow generates friction, thus achieving the washing effect. Front-loading washing machines, on the other hand, use the mechanical work of a motor to rotate the drum. The clothes are repeatedly lifted to a high position and then tumbled down within the drum, and this repeated motion achieves the washing of the clothes.

[0003] Compared to larger garments such as outerwear and trousers, smaller items like underwear are washed more frequently. Traditional washing machines (such as top-loading or front-loading washing machines) have a large capacity, so washing small items frequently would be wasteful of resources. Furthermore, because small items are usually small in size, the washing results may not meet expectations.

[0004] Currently, small washing machines specifically designed for washing small items of clothing have appeared on the market. These machines use a drum to hold the clothes, with protrusions on the drum wall. The drum rotates continuously in one direction, using the protrusions to rub against the clothes and wash small items. However, this friction-based washing method causes significant wear and tear on clothes, making it unsatisfactory.

[0005] To address this issue, the applicant proposed a solution in application No. 202110605197.1 dated May 31, 2021, which achieves washing by squeezing a flexible washing tub through the periodic movement of the squeezing part. However, in actual use, it was found that the impact force of the squeezing part on the flexible washing tub is insufficient, and there is still room for improvement in the washing effect. In order to solve this technical problem, this invention is proposed to make the solution more complete. Summary of the Invention

[0043] 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 connecting transmission component as including a worm gear and a worm, the present invention can obviously employ other similar means, such as the connecting transmission component including two meshing bevel gears, as long as the connecting transmission component can be connected to the stirring transmission component and the extrusion transmission component respectively.

[0044] It should be noted that in the description of this invention, terms such as "upper" and "lower" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0045] 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.

[0046] To address the technical issue of insufficient impact force from the squeezing section on the flexible washing tub in existing washing devices, resulting in room for improvement in washing performance, such as... Figure 1 , 2As shown in Figures 3A and 7, the present invention provides a washing device, including a support 1, a flexible washing tub 2, a squeezing section 3, a stirring section 8, and a driving section 4. The flexible washing tub 2 also has a discharge port 6. The flexible washing tub 2 includes an outer tub 21 and an inner tub 22. The outer tub 21 is fixedly mounted on the support 1, and the inner tub 22 is detachably disposed inside the outer tub 21. The flexible washing tub 2 also has pleats 5, which can provide sufficient deformation during the squeezing process. Figure 3A , 3B As shown, the stirring part 8 includes a pulsator 81 and a pulsator shaft 82 fixedly connected to the pulsator 81. The pulsator 81 is located inside the flexible washing tub 2. The bottom of the flexible washing tub 2 is provided with a through hole (not shown in the figure). The through hole is provided with a bearing seat 83. The bearing seat 83 is provided with a bearing 84 and a sealing block 85. The pulsator shaft 82 passes through the bearing 84 and is driven to the output end of the drive part 4.

[0047] like Figure 1 , 4 As shown in Figure -5, both the squeezing part 3 and the driving part 4 are located outside the flexible washing tub 2. There can be two squeezing parts 3. Each squeezing part 3 is pivotally connected to the support 1. The portion of the squeezing part 3 pivotally connected to the support 1 is located between the two ends of the squeezing part 3, and one end of the squeezing part 3 (specifically as shown in Figure -5) is... Figure 5 The top end of the squeezing part 3 shown in the figure abuts against the flexible washing tub 2, and the other end of the squeezing part 3 (specifically as shown in the figure) Figure 5 The bottom end of the squeezing part 3 (shown in the diagram) is driven to the output end of the driving part 4. A return spring 7 is also provided between the squeezing part 3 and the support 1, with both ends of the return spring 7 connected to the squeezing part 3 and the support 1, respectively. The end of the return spring 7 connected to the squeezing part 3 is located between the position where the squeezing part 3 is pivotally connected to the support 1 and the end where the squeezing part 3 abuts against the flexible washing tub 2. The output end of the driving part 4 is driven to the squeezing part 3 and the stirring part 8, respectively; under the drive of the driving part 4, the squeezing part 3 squeezes or releases the flexible washing tub 2, and the stirring part 8 stirs within the flexible washing tub 2.

[0048] like Figure 6-7 As shown, the drive unit 4 includes a drive component 41 (which may be a motor), a stirring transmission component 42, a pressing transmission component 43 (e.g., a cam), and a connecting transmission component 44. The connecting transmission component 44 includes a worm gear 441 and a worm 442 that is drivenly connected to the worm gear 441. The output end of the drive component 41 is drivenly connected to the worm 442. One side of the worm gear 441 is drivenly connected to the stirring transmission component 42 via a stirring transmission shaft 45, and the other side of the worm gear 441 is drivenly connected to the pressing transmission component 43 via a pressing transmission shaft 46.

[0049] like Figure 3B , 7As shown in Figure 8, the stirring transmission component 42 includes a first transmission wheel 421 and a second transmission wheel 422 that is pulverizedly connected to the first transmission wheel 421. When both the first transmission wheel 421 and the second transmission wheel 422 are gears, they can be meshed together. The first transmission wheel 421 is driven to the output end of the drive component 41, and the second transmission wheel 422 is pulverized to the stirring part 8. The pulverized transmission component 42 and the stirring part 8 are pulverized through the fixed connection between the second transmission wheel 422 and the impeller shaft 82. The first transmission wheel 421 and the second transmission wheel 422 are detachably connected for easy disassembly. The extrusion transmission component 43 also abuts against the end of the extrusion part 3 near the drive part 4.

[0050] like Figure 4-6 As shown, the squeezing part 3 includes two squeezing arms 31, which are detachably connected as a single unit. The adjacent ends of the two squeezing arms 31 are connected by a torsion spring 32, which is pivotally connected to the bracket 1. During normal washing, the two squeezing arms 31 do not move relative to each other due to the torsion of the torsion spring 32. However, if there is too much laundry in the flexible washing tub 2, causing the squeezing arms 31 to jam and fail to squeeze effectively, the lower squeezing arm 31 can overcome the torsion of the torsion spring 32 and continue moving under the action of the squeezing transmission member 43, thus preventing the squeezing transmission member 43 from jamming. The end of the squeezing part 3 that abuts against the flexible washing tub 2 is provided with a rotatable squeezing element 33, which can be a rotatable roller. Thus, during the squeezing process, the squeezing element 33 and the flexible washing tub 2 experience rolling friction, effectively reducing wear. Furthermore, the three squeezing elements 33 are arranged at an angle rather than vertically. This means that initially, not all three squeezing elements 33 need to be in contact with the flexible washing tub 2. At this point, the flexible washing tub 2 is squeezed, but only the bottom squeezing element 33 is in contact with it. This design ensures that the squeezing element 33 is not in contact with the flexible washing tub 2 at all times throughout the entire operating cycle, further reducing wear. In addition, the three angled squeezing elements 33 can also scoop up the clothes inside the flexible washing tub 2 from bottom to top with each squeeze, and then automatically drop the clothes when the squeezing is released, increasing the degree of tumbling of the clothes and improving washing efficiency.

[0051] The washing equipment also includes a position sensor (not shown in the figure), which is configured to provide feedback to the processor of the washing equipment regarding the position of the squeezing part 3 to determine whether the squeezing part 3 is currently squeezing the flexible washing tub 2. The position sensor includes a reed switch (not shown in the figure) and a magnet (not shown in the figure). One of the reed switch and the magnet is fixedly mounted on the bracket 1, and the other of the reed switch and the magnet is fixedly mounted on the squeezing part 3. When the squeezing part 3 pivots, the reed switch periodically opens or closes as the distance between the reed switch and the magnet changes. Thus, when the squeezing part 3 is not squeezing the flexible washing tub 2, the reed switch and the magnet are at their farthest distance. At this time, the processor detects that the reed switch is not open, indicating that the squeezing part 3 is not squeezing the flexible washing tub 2.

[0052] The washing equipment is also equipped with a backup power supply (not shown in the figure), which is connected to the drive unit 4 and the position sensing unit. In the event of an unexpected power outage while the laundry is being squeezed by the squeezing unit 3, the backup power supply can move the drive unit 4 to a position where it does not squeeze the flexible washing tub 2, thus avoiding prolonged squeezing of the laundry and affecting its service life. In addition, if it is anticipated that the power supply cannot be restored for a certain period of time, it is convenient to remove the laundry first.

[0053] The working principle of this invention will be explained below:

[0054] The driving component 41 drives the worm gear 442 to rotate, which in turn drives the worm wheel 441 to rotate. One side of the worm wheel 441 drives the extrusion transmission component 43 to rotate via the extrusion transmission shaft 46, while the other side of the worm wheel 441 drives the impeller 81 to rotate via the sequential connection of the stirring transmission shaft 45, the first transmission wheel 421, the second transmission wheel 422, and the impeller shaft 82. Simultaneously with the rotation of the extrusion transmission component 43, which is a cam, when the part of the extrusion transmission component 43 connected to the bottom end of the extrusion section 3 changes from one end of the short shaft to one end of the long shaft, the extrusion section 3 pivots, and its top end extrudes the flexible washing tub 2. When the part of the extrusion transmission component 43 connected to the bottom end of the extrusion section 3 changes from one end of the long shaft to one end of the short shaft, the extrusion section 3, under the action of the laundry and liquid inside the flexible washing tub 2, pivots again, returning to the position before the extrusion section 3 extrudes the flexible washing tub 2. This cycle repeats to achieve the washing of the laundry inside the flexible washing tub 2.

[0055] It should be noted that the above embodiments are merely used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles 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.

[0056] For example, in an alternative embodiment, the connecting transmission component may not include the worm gear and worm, but may include two meshing bevel gears (not shown in the figure), etc. As long as the connecting transmission component can be connected to the stirring transmission component and the extrusion transmission component respectively, it does not deviate from the principle of the present invention, and therefore will fall within the protection scope of the present invention.

[0057] For example, in another alternative embodiment, the position sensing unit (not shown in the figure) can also be located in other positions. For instance, a magnet (not shown in the figure) is fixedly mounted on the extrusion drive 43, and a reed switch (not shown in the figure) is fixedly mounted on a bracket near the extrusion drive 43. When the extrusion unit 3 pivots, the reed switch periodically opens or closes as the distance between the reed switch and the magnet changes. Magnets are fixedly mounted at both ends of the long shaft of the extrusion drive 43, and a reed switch is mounted on the bracket, so that when the extrusion unit 3 is in the state of not extruding the flexible washing tub 2, the reed switch can be at the closest distance to one of the two magnets. At this time, the processor detects that the reed switch is connected, indicating that the extrusion unit 3 is in the state of not extruding the flexible washing tub 2. In this embodiment, two reed switches can also be used, which does not deviate from the principle of the present invention and therefore all fall within the protection scope of the present invention.

[0058] For example, in the previous alternative embodiment, an infrared sensor (not shown in the figure) can be used instead of a reed switch and a magnet. Specifically, the reed switch and magnet can be omitted, and the infrared sensor can be placed in the position of the reed switch. The infrared sensor is placed on a bracket near the extrusion drive 43, specifically at the bottom end of the extrusion drive 43. Utilizing the structural feature of the extrusion drive 43 as a cam with a long axis and a short axis, when the extrusion drive 43 rotates, there is a difference in the area that the two ends of the long axis and the two ends of the short axis of the extrusion drive 43 can block. When the two ends of the long axis of the extrusion drive 43 block the infrared sensor, the infrared light emitted by the infrared sensor is reflected by the extrusion drive 43 and then received by the infrared sensor again, indicating that the extrusion part 3 is in a state where the flexible washing tub 2 is not extruded. These do not deviate from the principle of the present invention and therefore all fall within the protection scope of the present invention.

[0059] In summary, the washing device of the present invention washes clothes through a reciprocating squeezing washing method. During squeezing, the water absorbed by the clothes is expelled, releasing the water adsorbed during the squeezing process. Simultaneously, a pulsator washes the clothes synchronously, resulting in a better washing effect. Furthermore, the washing device of the present invention is equipped with a position sensor, allowing the squeezing section to remain in an unsqueezed flexible washing tub state after washing, facilitating the removal of clothes from the tub. The present invention also includes a backup power supply, so that even in the event of a power outage, the squeezing section can be adjusted to remain in an unsqueezed flexible washing tub state.

[0060] Those skilled in the art will understand that the above-described washing equipment 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.

[0061] 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.
