Description

Technical Field

[0001] This invention belongs to the field of washing technology, specifically relating to a flexible washing tub and washing equipment. Background Technology

[0002] In today's daily life, with the continuous development and progress of society, people are paying more attention to their personal hygiene. Consequently, people wash their clothes more frequently. Therefore, fully automatic washing machines have brought increasing convenience and become an indispensable household appliance. Currently, there are two common types of washing machines: top-loading washing machines and front-loading washing machines. Compared to outerwear and trousers, smaller items like underwear are washed more frequently. Traditional washing machines (such as top-loading or front-loading machines) have a large capacity, and 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.

[0003] Currently, small washing machines specifically designed for small items of clothing have appeared on the market. These machines use a washing drum to hold the clothes, and the drum wall has protrusions. The washing 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.

[0004] To address this issue, a washing method simulating hand washing has emerged, employing external compression of a flexible washing tub to achieve a good washing effect without damaging clothes. However, the dehydration problem of the flexible washing tub has yet to be effectively solved. Traditional washing machines have a rigid tub structure, allowing for centrifugal dehydration through high-speed rotation. However, flexible washing tubs are typically used in small washing equipment, usually as a single tub. Since a single tub must maintain a sealed structure during washing, designing drainage holes on the side wall, as in conventional washing machine tubs, would lead to leaks and prevent washing from completing. Therefore, current washing equipment with a single flexible washing tub cannot utilize centrifugal dehydration; instead, it relies on creating negative pressure by extracting air from the tub to squeeze and dehydrate. However, this dehydration method is still not ideal, leaving clothes with a high moisture content even after squeezing and dehydration.

[0005] Accordingly, there is a need in the art for a new flexible washing tub and washing equipment to solve the problem of unsatisfactory dehydration effect of the aforementioned flexible washing tubs in the prior art. Summary of the Invention

[0006] To address the problem of unsatisfactory dehydration effect in existing flexible washing tubs, this invention provides a flexible washing tub, including a tub body, a water-removing channel provided on the side wall of the tub body, a water-gathering channel provided on the bottom wall of the tub body, the water-removing channel communicating with the water-gathering channel, the water-gathering channel communicating with the outer bottom of the tub body through a water-gathering port, and the inner side of the tub body communicating with the water-removing channel through a water-removing hole.

[0007] In the preferred embodiment of the above-mentioned flexible washing tub, the flexible washing tub further includes a base, the tub body is fixedly mounted on the base, and the base and the tub body enclose the water collection channel.

[0008] In the preferred embodiment of the above-mentioned flexible washing tub, a first groove is provided on the base, and the first groove and the outer surface of the bottom wall of the tub body form the water collection channel, or...

[0009] The bottom outer surface of the barrel is provided with a second groove, which together with the base forms the water collection channel.

[0010] In the preferred embodiment of the above-mentioned flexible washing tub, one end of the water collection port is connected to the interior of the tub body, the other end of the water collection port passes through the base and is connected to the exterior of the base, and the water collection channel is connected to the exterior of the base through the water collection port.

[0011] In the preferred embodiment of the above-mentioned flexible washing tub, the water collection channel is disposed between the outer and inner sides of the bottom wall of the tub body.

[0012] In the preferred embodiment of the above-mentioned flexible washing tub, the side wall of the tub body is provided with ribs, the water separation channel is located inside the ribs, and the water separation hole is located on the ribs.

[0013] In the preferred embodiment of the above-mentioned flexible washing tub, the greater the distance between the water-discharging hole and the water-discharging channel, the smaller its size, and / or,

[0014] The farther the water-discharging hole is from the water-discharging channel, the farther it is from the bottom of the barrel.

[0015] The present invention also provides a washing device, which includes a flexible washing tub as described in any of the above technical solutions.

[0016] In the preferred embodiment of the washing equipment described above, the washing equipment further includes a drain pipe, which is rotatably and sealingly connected to the water inlet.

[0017] In the preferred embodiment of the above-mentioned washing equipment, the washing equipment further includes a cover, which is disposed on the top of the tub. A roller is also provided on the cover, which is rotatably connected to the cover and abuts against the top edge of the tub.

[0018] Those skilled in the art will understand that, in the technical solution of the present invention, the flexible washing tub includes a tub body, a water-removing channel is provided on the side wall of the tub body, a water-gathering channel is provided on the bottom wall of the tub body, the water-removing channel is connected to the water-gathering channel, the water-gathering channel is connected to the outer bottom of the tub body through a water-gathering port, and the inner side of the tub body is connected to the water-removing channel through a water-removing hole.

[0019] With the above-described configuration, the water removed by centrifugation from the clothes inside the flexible washing tub of the present invention enters the water-removing channel on the side wall of the tub body through the water-removing hole, then enters the water-collecting channel at the bottom of the tub body, and finally exits from the water-collecting outlet to the outside of the flexible washing tub. This ensures that even when the flexible washing tub of the present invention is in a single-tub form, it can still effectively remove moisture from the clothes inside the flexible washing tub through centrifugal rotation while maintaining the tub's airtightness.

Detailed Implementation

[0033] 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 water-removing hole as being located only on one side of the rib near the side wall of the tub, the present invention can obviously employ other similar methods, such as providing the water-removing hole on both sides of the rib near the side wall of the tub, as long as the water-removing hole allows water separated by the centrifugal motion of the clothing to easily enter the water-removing channel.

[0034] It should be noted that in the description of this invention, terms such as "center," "upper," "lower," "left," "right," "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," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] 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 mechanical connection or an electrical 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.

[0036] To address the problem of unsatisfactory dehydration performance in existing flexible washing tubs, such as... Figure 1 As shown, the present invention provides a flexible washing tub, including a tub body 1 and a base 6, wherein the tub body 1 is fixedly mounted on the base 6, as... Figure 2-3B As shown, a rib 8 is also provided on the side wall of the barrel 1. A water separation channel 2 is located inside the rib 8. The inner side of the barrel 1 communicates with the water separation channel 2 through a water separation hole 4, which is located on the rib 8. The rib 8 not only facilitates the installation of the water separation channel 2 and the water separation hole 4, but also, because it is located on the side wall of the barrel 1, increases the thickness of the side wall, acting like a reinforcing plate and improving the structural strength of the barrel 1. Multiple water separation holes 4 can be provided, and to ensure that the water removed by centrifugation can smoothly enter the water separation channel 2 from the water separation holes 4, the water separation holes 4 are usually only located on the same side of the rib 8, such as... Figure 2 and 3B As shown, the water separation hole 4 is located on the right side of the rib 8 when viewed from above. However, if the water separation hole 4 is located on both sides of the rib 8, during the centrifugal dehydration process, water separated by centrifugation may enter the water separation channel 2 from one side of the rib 8 and then leave the water separation channel 2 from the other side of the rib 8, affecting the centrifugal dehydration effect.

[0037] like Figure 3B-5 As shown, a first groove 31 is provided on the base 6, and the first groove 31 and the outer surface of the bottom wall of the barrel 1 form a water-collecting channel 3. The water-discharging channel 2 is connected to the water-collecting channel 3. One end of the water-collecting port 5 is connected to the inside of the barrel 1 through the water-collecting channel 3, the water-discharging channel 2, and the water-discharging hole 4. A passage can also be added to the water-collecting port 5 to connect directly to the bottom of the barrel 1. The other end of the water-collecting port 5 passes through the base 6 and is connected to the outside of the base 6, so that the water-collecting channel 3 is connected to the outside of the base 6 through the water-collecting port 5. This arrangement ensures that the centrifuged water flows into the water-discharging hole 4, the water-discharging channel 2, and the water-collecting channel 3 and then discharges, while excess water is discharged directly from the water-collecting port 5 at the center of the barrel 1.

[0038] The end of the water separation channel 2 that is not connected to the water separation hole 4 passes through the bottom wall of the rib 8 and the barrel 1 in sequence and then connects to the water collection channel 3.

[0039] 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.

[0040] For example, in an alternative embodiment, the water-discharging hole 4 can be provided only on one side of the rib 8 near the side wall of the tub 1, instead of being provided on both sides of the rib 8 near the side wall of the tub 1, as long as the water-discharging hole 4 allows water separated by the centrifugal motion of the clothes to easily enter the water-discharging channel 2. Specifically, the rib 8 can be provided with multiple water-discharging holes 4 and the same number of water-discharging channels 2 as the water-discharging holes 4. Each water-discharging channel 2 communicates with only one water-discharging hole 4, and all multiple water-discharging channels 2 communicate with the water-gathering channel 3 (not shown in the figure). These implementations do not deviate from the principle of the present invention and therefore fall within the protection scope of the present invention.

[0041] For example, in another alternative embodiment, the base 6 may be provided with a first groove 31, and the first groove 31 and the outer surface of the bottom wall of the barrel 1 may form a water collection channel 3. Alternatively, the bottom outer surface of the barrel 1 may be provided with a second groove (not shown in the figure), and the second groove and the base 6 may form a water collection channel. These alternatives do not deviate from the principle of the present invention and therefore all fall within the protection scope of the present invention.

[0042] For example, in another alternative embodiment, a first groove 31 can be provided on the base 6, and a water collection channel 3 can be formed by the first groove 31 and the outer surface of the bottom wall of the barrel 1. A third groove (not shown in the figure) can be provided on the bottom outer surface of the barrel 1. The first groove 31 and the third groove together form a water collection channel. These do not deviate from the principle of the present invention, and therefore all fall within the protection scope of the present invention.

[0043] For example, in another alternative embodiment, the base 6 may be provided with a first groove 31, and the first groove 31 and the outer surface of the bottom wall of the barrel 1 may form a water-gathering channel 3. Alternatively, the base 6 and the first groove 31 may not be provided, and the water-gathering channel 3 may be provided between the outer side (here, the outer side refers to the side closest to the outer side of the barrel 1) and the inner side (here, the inner side refers to the side closest to the inner side of the barrel 1) of the bottom wall of the barrel 1. Specifically, the water-gathering channel 3 may be provided in the middle part of the bottom wall of the barrel 1. In this case, the end of the water-removing channel 2 that is not connected to the water-removing hole 4 passes through the rib 8 and then connects to the water-gathering channel 3. These embodiments do not deviate from the principle of the present invention and therefore all fall within the protection scope of the present invention.

[0044] For example, in another alternative embodiment, the ribs 8 may not be provided on the side wall of the barrel 1, and the corresponding water-removing channel 2 may not be located inside the ribs 8. Instead, the water-removing channel 2 may be directly located in the middle part of the side wall of the barrel 1 (the middle part of the side wall refers to the part between the inner and outer sides of the side wall). Correspondingly, the water-removing hole 4 may also be located in the side wall of the barrel 1. One end of the water-removing channel 2 communicates with the water-removing hole 4 on the side wall of the barrel 1, and the other end of the water-removing channel 2 passes through the side wall of the barrel 1 and communicates with the water-gathering channel 3. These arrangements do not deviate from the principle of the present invention and therefore all fall within the protection scope of the present invention.

[0045] For example, in another alternative embodiment, the water-discharging hole 4 can be configured to decrease in size as it gets farther from the water-discharging channel 2 (not shown in the figure). This is because the water that has detached from the clothes due to centrifugal motion enters the water-discharging hole 4 with a relatively large impact force. Conventional, uniformly sized channel structures may not allow all the water to smoothly enter the water-discharging hole 4 due to excessive impact force, thus affecting the dehydration effect. Therefore, in this embodiment, the water-discharging hole 4 allows the water that has detached from the clothes after centrifugation to smoothly enter the water-discharging channel 2. Since conventional centrifugal dehydration techniques typically use a double-bucket setup, consisting of an outer bucket and a rotatable inner bucket with a dehydration hole, and the dehydration hole is small, no special design is required. However, in this embodiment, the water that has detached from the clothes needs to pass through the water-discharging hole 4 and the water-discharging channel 2, traveling a much longer distance than in a double-bucket setup. Therefore, configuring the water-discharging hole 4 to decrease in size as it gets farther from the water-discharging channel 2 achieves excellent results, a solution that would be difficult for someone skilled in the art to conceive of. These do not deviate from the principles of the present invention, and therefore all fall within the protection scope of the present invention.

[0046] For example, in another alternative embodiment, the water-removing hole 4 can be configured to be farther from the bottom of the tub 1 as it is farther from the water-removing channel 2 (not shown in the figure). In this embodiment, the water-removing hole 4 is tilted upwards. Water that has been separated from the clothes due to the centrifugal motion of the clothes enters the water-removing hole 4 and is less likely to escape. Moreover, it can accelerate the movement speed of water within the water-removing hole 4, thereby improving the centrifugal dehydration effect of the flexible washing tub on the clothes. These all do not deviate from the principle of the present invention and therefore fall within the protection scope of the present invention.

[0047] In existing technologies, the reason why various washing equipment uses flexible washing tubs is precisely to take advantage of their flexibility and deformability. Compared to conventional rigid washing tubs, flexible washing tubs typically employ external force applied to the tub during the washing process to achieve squeezing and washing, resulting in less wear and tear on clothes compared to other washing methods. Flexible washing tubs are usually designed as single-tub units. To ensure the effectiveness of squeezing and washing, the flexible washing tub must be sealed. However, a sealed flexible washing tub obviously cannot perform centrifugal dehydration. Therefore, the current conventional technique involves extracting air from the flexible washing tub to create negative pressure, and then squeezing and dehydrating the clothes. However, this dehydration method is not only less than ideal in terms of dehydration effect, leaving clothes with a high moisture content even after squeezing and dehydration, but also, because of the additional squeezing and dehydration, the clothes are subjected to repeated squeezing and additional external forces unrelated to washing during the final dehydration stage, increasing the likelihood of wear and tear on the clothes.

[0048] In existing technology, many washing machines typically use rigid washing tubs and employ centrifugal spin-drying. This method is effective at dehydrating clothes, and as the clothes rotate in the tub, centrifugal force causes them to adhere to the inner wall of the tub, resulting in minimal relative movement between the clothes and the tub. Consequently, the clothes experience less wear and tear during the centrifugal spin-drying process.

[0049] While centrifugal dehydration is superior to the negative pressure squeezing dehydration method currently used in flexible washing tubs, achieving centrifugal dehydration requires dehydration holes on the side wall of the flexible washing tub. This obviously conflicts with the sealing required for flexible washing tubs during washing, thus conventional flexible washing tubs cannot use centrifugal dehydration. Those skilled in the art, when needing to dehydrate flexible washing tubs using centrifugal dehydration, readily think of using a double-tub form similar to rigid washing tubs in existing technology. That is, setting up two flexible washing tubs, one inner and one outer, with dehydration holes on the side wall of the inner flexible washing tub. While this method can achieve centrifugal dehydration in flexible washing tubs, flexible washing tubs typically use squeezing washing. Setting up two flexible washing tubs not only increases costs, but also, if the two flexible washing tubs are set with a certain gap to facilitate centrifugal dehydration in the inner flexible washing tub, this structure will affect the squeezing washing effect; if the two flexible washing tubs are set with no gap or a very small gap, it will greatly affect the centrifugal dehydration effect of the inner flexible washing tub, making it not much different from a single-tub flexible washing tub.

[0050] Therefore, this invention creatively incorporates a water-discharging channel 2, a water-discharging hole 4, and a water-gathering channel 3, with the water-gathering channel 3 connected to the water-gathering outlet 5. Water removed by centrifugation from the clothes inside the flexible washing tub enters the water-discharging channel 2 on the side wall of the tub body 1 through the water-discharging hole 4, then enters the water-gathering channel 3 at the bottom of the tub body 1, and finally exits from the water-gathering outlet 5 to the outside of the flexible washing tub. This allows the flexible washing tub of this invention, even in a single-tub form, to effectively remove moisture from the clothes inside through centrifugal rotation, just like a conventional rigid washing tub, while maintaining its airtightness. This is something that those skilled in the art would find difficult to conceive of.

[0051] Furthermore, the present invention also provides a washing apparatus having the flexible washing tub described in any of the above embodiments. For example... Figure 2 and 6 As shown, Figure 6 This is a schematic diagram of the washing device of the present invention. Since the improvements to the washing device in this invention involve the flexible washing tub and related parts, other structures of the washing device, such as the squeezing part, are not shown in the diagram and are not described in words. The washing device also includes a drain pipe 9, which is rotatably sealed to the water collection port 5. When the tub body 1 of the flexible washing tub rotates, the drain pipe 9 does not rotate with the tub body 1, so that the water discharged from the water collection port 5 can be discharged through the drain pipe 9. Figure 7 As shown, the washing equipment also includes a cover 10, which is disposed on the top of the tub 1. A roller 11 is also provided on the cover 10, and the roller 11 is rotatably connected to the cover 10, abutting against the top edge of the tub 1. The cover 10 is fixedly disposed to facilitate the introduction of water into the tub 1 of the flexible washing tub through a water inlet pipe (not shown in the figure), and to accommodate an air pipe (not shown in the figure) for maintaining air pressure balance within the tub 1. The roller 11 reduces the friction between the tub 1 and the cover 10 when the tub 1 rotates.

[0052] When it is necessary to drive the barrel 1 to rotate, since the drain pipe 9 does not rotate, a connecting pipe 12 can be installed at the water inlet 5 to facilitate the rotation of the barrel 1. This allows the connecting pipe 12 to rotate synchronously with the barrel 1, and correspondingly, the drain pipe 9 and the connecting pipe 12 are rotatably and sealed together. A worm gear 14 is fitted on the outside of the connecting pipe 12, and the worm gear 14 is connected to the worm 15 for transmission. The worm 15 is then connected to the output end of the motor 13 for driving. Figure 2 As shown, when the water-removing hole 4 is only set on the same side of the rib 8, the rotation direction of the bucket 1 also needs to be set so that the water that is separated from the clothes by centrifugal rotation can enter the water-removing hole 4. And the rotation direction of the bucket 1 is also different depending on the position of the water-removing hole 4 on the rib 8.

[0053] During the washing process of clothes in tub 1, a drain valve (not shown in the figure) is usually installed on the drain pipe 9 to ensure washing effect. When centrifugal spin-drying is required, the drain valve is opened. Specifically, during spin-drying, the drain valve can be opened for 60 seconds to discharge most of the water in tub 1 from the water collection port 5 through the drain pipe 9, after which tub 1 rotates at high speed. The rotation sequence can be 1 second, 2 seconds, 2 seconds, 3 seconds, 2 seconds, etc., until spin-drying is complete. The purpose of stopping the rotation of tub 1 is to allow the water that has been removed from the clothes after centrifugal rotation to enter the water collection channel 3.

[0054] For example, in another alternative embodiment, instead of having rollers 11 on the cover 10, the cover 10 may be detachably connected to the bucket 1, and the cover 10 and the bucket 1 may rotate synchronously. The corresponding water inlet pipe (not shown in the figure) may be configured to pass through the center of the cover 10 and be rotatably connected to the cover 10. These configurations do not deviate from the principles of the present invention and therefore fall within the protection scope of the present invention.

[0055] For example, in another alternative embodiment, the connecting pipe 12 may not be provided. Instead, one end of the water inlet 5 that communicates with the outside of the barrel 1 extends directly to the outside of the barrel 1 and is directly and rotatably sealed to the drain pipe 9. The worm gear 14 is sleeved on the outside of the part of the water inlet 5 located outside the barrel 1 (not shown in the figure). These do not deviate from the principle of the present invention and therefore all fall within the protection scope of the present invention.

[0056] For example, in another alternative implementation, such as Figure 8A-9 As shown, the connection between the water inlet 5 and the barrel 1 can also be in other ways, that is, the water inlet 5 is not directly connected to the barrel 1 from the bottom of the barrel 1, but the water inlet 5 is only connected to the inside of the barrel 1 through the water collection channel 3, the water separation channel 2, and the water separation hole 4. These do not deviate from the principle of the present invention, and therefore all fall within the protection scope of the present invention.

[0057] The washing equipment of the present invention enables a single-tub flexible washing tub to be dehydrated by centrifugal rotation, which significantly improves the dehydration effect.

[0058] 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.

[0059] 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.
