Description

Pulsator washing machine and washing barrel assembly and water channel assembly thereof

Technical Field

The invention belongs to the field of clothes treatment equipment, and particularly provides a pulsator washing machine and a washing barrel assembly and a water channel assembly thereof.

Background

The pulsator washing machine mainly comprises a box body, an outer barrel, an inner barrel and a pulsator. Wherein, the outer barrel is fixedly arranged in the box body, the inner barrel is rotatably arranged in the outer barrel, and the wave wheel is rotatably arranged at the bottom of the outer barrel. When the pulsator washing machine performs washing and rinsing operations, the pulsator drives the washing water and the laundry in the outer tub to rotate, so as to achieve the purpose of washing the laundry. When the rotary drum washing machine performs spin-drying operation, the inner barrel drives the clothes in the inner barrel to rotate at high speed, so that the moisture on the clothes is separated from the clothes under the action of centrifugal force.

The pulsator washing machine often has the following problems in the use process: firstly, washing powder and laundry detergent are deposited at the bottom of an outer barrel and are not easily dissolved by washing water; secondly, when the number of the washed clothes is large, the condition that part of the clothes is not soaked by the washing water is easy to occur; thirdly, the down and other clothes often float above the level of the washing water during washing, and the washing effect is poor.

Accordingly, there is a need in the art for a new pulsator washing machine, and a washing tub assembly and a water passage assembly thereof to solve the above-mentioned problems.

In order to solve the above problems in the prior art, that is, to solve the problem that the conventional pulsator washing machine has a poor washing effect on the clothes floating above the liquid level of the washing water, the present invention provides a washing tub assembly of the pulsator washing machine, which includes a washing tub, a kick channel and a flow guide member, wherein the kick channel is disposed on the washing tub, and a first end of the kick channel is open to the top of the washing tub, and a second end of the kick channel is open to the bottom of the washing tub; the flow guide member is disposed at the top of the washing tub, and the flow guide member is aligned with the first end of the upwelling channel; the upwelling passage can deliver the washing water in the washing tub to the guide member, which can flow the washing water in a radial direction of the washing tub and finally fall back into the washing tub.

In a preferred embodiment of the above washing tub assembly, the flow guide member includes a flow guide plate disposed along a circumferential direction of the washing tub and used for carrying the washing water.

In a preferred technical solution of the above washing tub assembly, a diversion trench is disposed on one side of the diversion plate close to the upwelling channel, the diversion trench is disposed along a circumferential direction of the washing tub, and the diversion trench is used for guiding the washing water along the circumferential direction of the washing tub and uniformly distributing the washing water on the diversion plate.

In a preferred embodiment of the above washing tub assembly, the washing tub assembly further includes a waterway member having a groove, the waterway member is fixedly connected to or integrally formed with the sidewall of the washing tub, and thus the upwelling channel is formed between the waterway member and the washing tub.

In a preferred embodiment of the above washing tub assembly, the waterway member is fixedly connected to or integrally formed with the guide plate.

In a preferred embodiment of the above washing tub assembly, the flow guide member includes a water blocking member disposed along a circumferential direction of the washing tub, and the water blocking member is configured to block and scatter the washing water along an axial direction of the washing tub.

In a preferred technical solution of the above washing tub assembly, the washing tub is an outer tub of the pulsator washing machine, and the water blocking member is an outer tub cover disposed on the outer tub; and/or the washing barrel is an inner barrel of the pulsator washing machine, and the water blocking member is a balance ring arranged on the inner barrel; and/or the upwelling channel is multiple.

In addition, the invention also provides a water channel component for the pulsator washing machine, the water channel component is arranged on an outer barrel or an inner barrel of the pulsator washing machine, the water channel component comprises a water channel component and a guide plate arranged at one end of the water channel component, and the water channel component and the guide plate are fixedly connected or integrally manufactured; the waterway member may transfer the washing water in the outer tub to the guide plate, and the guide plate may carry and make the washing water flow in a radial direction of the outer tub and finally fall back into the outer tub.

In a preferred embodiment of the above water channel assembly, the water channel member is provided with an upwelling channel capable of conveying the washing water; or, the water channel member is provided with a groove, and when the water channel member is mounted on the outer barrel or the inner barrel, an upwelling channel capable of conveying the washing water is formed between the water channel member and the outer barrel or the inner barrel.

In addition, the present invention also provides a pulsator washing machine including the washing tub assembly as set forth in any one of the above preferred embodiments, the upwelling passage being provided such that the washing water in the washing tub enters the upwelling passage and is spouted out from the first end of the upwelling passage when the pulsator rotates.

It should be understood by those skilled in the art that the embodiments of the present invention are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. For example, the pulsator washing machine of the present invention may or may not include an inner tub. When the pulsator washing machine comprises an inner barrel, the water channel assembly is arranged on the inner barrel; when the pulsator washing machine does not comprise an inner barrel, the water channel assembly is arranged on the outer barrel. Those skilled in the art can make modifications as needed to suit a particular application, and such modifications will still fall within the scope of the present invention.

It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicating the directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Furthermore, it should be noted that, in the description of the present invention, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As shown in fig. 1 to 3, the pulsator washing machine of the present invention mainly includes a cabinet 1, an outer tub 2, an inner tub 3, a pulsator 4, and a driving motor 5. Wherein, the outer tub 2 is fixedly disposed inside the cabinet 1, the inner tub 3 is rotatably disposed in the outer tub 2, and the pulsator 4 is rotatably disposed at the bottom of the inner tub 3. The driving motor 5 is fixedly installed on the box body 1 or the outer tub 2, and the driving motor 5 is respectively connected with the inner tub 3 and the pulsator 4 in a driving manner through a rotating shaft. The driving motor 5 can selectively drive the inner tube 3 and the impeller 4 to rotate. Since the technical means of the driving motor 5 selectively driving the inner tube 3 and the pulsator 4 is well known to those skilled in the art, it will not be described herein too much.

As shown in fig. 1, a door cover 11 is pivotally attached to the top of the cabinet 1 of the present invention.

As shown in fig. 2, the top of the outer tub 2 of the present invention is provided with an outer tub cover 21, and the outer tub cover 21 is used for shielding the upper edge of the inner tub 3 to prevent the laundry from entering into the interlayer between the outer tub 2 and the inner tub 3.

As shown in fig. 3, the top of the inner tub 3 of the present invention is provided with a balance ring 31. The balance ring 31 can increase the moment of inertia of the inner tub 3 and reduce the vibration of the inner tub 3 when rotating.

As shown in fig. 3 to 5, the pulsator washing machine of the present invention further includes a water passage assembly 6 disposed inside the inner tub 3. An upwelling channel (not shown) is formed between the water channel assembly 6 and the inner tub 3. Wherein a first end of the upwelling channel (the upper end of the water channel assembly 6 in fig. 3) is open to the top of the inner tub 3, and a second end of the upwelling channel (the lower end of the water channel assembly 6 in fig. 3) is open to the bottom of the inner tub 3. The washing water in the inner tub 3 can flow along the circumferential direction of the inner tub 3 along with the rotation of the pulsator 4, and the flowing washing water enters the upwelling channel from the second end thereof under the action of centrifugal force, and flows toward the first end along the vertical direction, and is then sprayed out from the first end of the upwelling channel. The washing water sprayed from the upwelling passage passes through the guide member and then falls back into the inner tub 3 again.

In a preferred embodiment of the present invention, the flow directing member comprises at least one of a baffle 62 (shown in fig. 6 and 7) and a water retaining member of the waterway assembly 6.

As shown in fig. 3 and 4, a gap H is provided between the upper end of the waterway assembly 6 and the balance ring 31 as a water blocking member. Preferably, 0mm < H < 50 mm. Further preferably, 2mm ≦ H < 10 mm. Still more preferably, 2.5mm ≦ H ≦ 5.5 mm. When the washing water is sprayed from the upwelling path, the washing water hits the balance ring 31 and is scattered by the balance ring 31. The scattered washing water flows out from the gap between the waterway assembly 6 and the balance ring 31, and falls back into the inner tub 3 again.

Although not shown explicitly, in the preferred embodiment of the present invention, the balance ring 31 can block the upper end of the water channel assembly 6 in the axial direction, i.e., looking down along the axial direction of the inner barrel 3, only the balance ring 31 can be seen and the upper end of the water channel assembly 6 can not be seen. So as to prevent the upper end of the waterway assembly 6 from catching the laundry, and the laundry can be smoothly inputted into the inner tub 3. In addition, a person skilled in the art can also shield the upper end of the water channel assembly 6 by the outer tub cover 21, and at this time, the balance ring 31 may shield the upper end of the water channel assembly 6 or not.

It will be appreciated by those skilled in the art that the number of waterway assemblies 6 is not limited to two as shown in fig. 5, but may be any other number, such as one, three, four, five, etc.

As shown in fig. 6 and 7, the waterway assembly 6 of the present invention mainly includes a waterway member 61 and a baffle plate 62. Wherein the waterway member 61 and the baffle plate 62 may be coupled together in any feasible manner, such as snap-fit, screw-fit, etc. Further, those skilled in the art may integrally form the waterway member 61 and the baffle plate 62 as necessary. Or, the skilled person may separately install the water channel member 61 and the guide plate 62 as needed, so that the water channel member 61 and the guide plate 62 are respectively fixed to the inner tub 3.

As shown in fig. 5 and 7, a groove 611 is provided at a side of the waterway member 61 facing the sidewall of the inner tub 3. After the water channel member 61 is mounted on the inner tub 3, the water channel member 61 and the inner tub 3 enclose the groove 611 as the upwelling channel. It will be understood by those skilled in the art that the waterway member 61 and the inner barrel 3 may be connected together by any feasible connection means, such as screw connection, plug connection, snap connection, etc. Or those skilled in the art may integrally form the waterway member 61 and the inner tub 3 as needed.

Further, those skilled in the art may also arrange the groove 611 in a circumferentially closed configuration, even if the upwelling channel is formed directly on the waterway member 61, as desired.

As shown in fig. 3 and 6, a side of the waterway member 61 away from the sidewall of the inner tub 3 is provided with a plurality of friction protrusions 612. The friction protrusion 612 serves to frictionally flap the laundry so as to accelerate dissolution of contaminants on the laundry into the washing water.

As shown in fig. 5 to 7, the guide plate 62 has a curvature matched with the inner tub 3 so that the guide plate 62 can be fixed to the inner tub 3 in a circumferential direction of the inner tub 3. It can be understood by those skilled in the art that the guide plate 62 may also be integrally formed with the inner tub 3 when the waterway member 61 and the guide plate 62 are separately provided. Further, the baffle plate 62 also extends in a radial (or approximately radial) direction of the inner tub 3, so that the baffle plate 62 can carry the washing water sprayed from the upwelling channel (groove 611) and guide the washing water to flow in the radial direction of the inner tub 3. Preferably, the upper surface of the baffle 62 is disposed parallel to the lower surface of the balancing ring 31, and both are disposed horizontally. Or the upper surface of the baffle plate 62 and the lower surface of the balancing ring 31 may be arranged in a non-parallel manner, even if there is a certain included angle therebetween, as required by those skilled in the art. For example, the lower surface of the balancing ring 31 is horizontally disposed, and the upper surface of the baffle plate 62 is obliquely upwardly disposed, so that the washing water is sprayed farther.

With continued reference to fig. 5 to 7, two diversion trenches 621 are symmetrically disposed on the side of the diversion plate 62 near the groove 611. The two guide grooves 621 are respectively formed along the circumferential direction of the inner tub 3. The two guide grooves 621 serve to guide the washing water to be uniformly distributed on the guide plate 62 along the circumferential direction of the inner tub 3, thereby allowing the washing water to uniformly fall back into the inner tub 3 along the circumferential direction of the inner tub 3.

The spraying operation principle of the pulsator washing machine of the present invention will be described in detail with reference to fig. 3, 5 to 7.

When the pulsator washing machine is operated, the rotating pulsator 4 drives the washing water in the inner tub 3 to flow along the circumferential direction of the inner tub 3. The flowing washing water is thrown into the upwelling channel (groove 611) by the centrifugal force. The washing water introduced into the upwelling channel (groove 611) later drives the washing water introduced into the upwelling channel (groove 611) earlier upward until being spouted out from the upper end of the upwelling channel (groove 611). A part of the washing water sprayed from the upwelling channel (the groove 611) is uniformly flowed to the guide plate 62 along the circumferential direction of the inner tub 3 by the guide groove 621. Another portion of the washing water sprayed from the upwelling channel (groove 611) hits the balance ring 31 and is scattered and reflected by the balance ring 31 to the deflector 62. The washing water on the guide plate 62 flows along the radial direction of the inner tub 3 and finally falls back into the inner tub 3 to spray the laundry in the inner tub 3.

Based on the above description, it can be understood by those skilled in the art that the present invention can deliver the washing water from the bottom of the inner tub 3 to the top of the inner tub 3 through the upwelling channel (groove 611), scatter and reflect the washing water sprayed from the upwelling channel (groove 611) to the guide plate 62 through the balance ring 31, and uniformly drop the washing water back into the inner tub 3 along the circumferential direction of the inner tub 3 through the guide plate 62 to spray the laundry in the inner tub 3. As will be understood by those skilled in the art, the washing water can flow in the radial direction of the inner tub 3 and closer to the axial center of the inner tub 3 by the guide plate 62. Therefore, when the washing water flows down from the guide plate 62, the landing point of the washing water can be closer to the axis of the inner tub 3, or the axis position of the inner tub 3 can be directly covered, and the clothes floating above the water level of the washing water can be sprayed three-dimensionally and omnidirectionally.

In addition, a separate water blocking member may be provided instead of the balancing ring 31 to scatter and reflect the washing water to the deflector 62, as needed by those skilled in the art. The water blocking member is a plate-shaped structure disposed on the outer tub 3 and located above the flow guide plate 62, and the plate-shaped structure may be a ring-shaped structure or a semicircular structure.

In addition, the present invention provides a washing tub assembly, which mainly includes the above-described inner tub 3, the balancing ring 31 as a water blocking member, and the water passage assembly 6.

Although not shown in the drawings, in another possible embodiment of the present invention, unlike the above-described preferred embodiment, the pulsator washing machine does not include the inner tub 3, the water channel assembly 6 is mounted to or integrally formed with the outer tub 2, and the guide plate 62 at the upper end of the water channel assembly 6 is shielded by the outer tub cover 21. Correspondingly, the washing tub assembly mainly includes the outer tub 2, the outer tub cover 21 as a water blocking member, and the water passage assembly 6 as described above.

Although not shown in the drawings, in yet another possible embodiment of the present invention, unlike the above-described preferred embodiment, the pulsator washing machine does not include the waterway member 61, and the upwelling channel is directly formed on the inner tub 3. Correspondingly, the washing tub assembly mainly includes the inner tub 3 described above, the balance ring 31 as a water blocking member, and the baffle plate 62.

So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent alterations and substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the alterations and the substitutions falls within the protection scope of the invention.
