The water flow in between is drained out of the casing 4 'through the drain port 7', the drain valve 8 ', and the drain pipe 9' at the bottom of the outer tub 3 ', and the water in the inner tub 2' is discharged through the dewatering hole 21 'and the outer tub 3 'Keep the liquid level consistent until the water in the last inner bucket 2' flows down It moves into the outer tub 3 'from the drain hole 22' at the bottom of the inner tub 2 ', and then discharges from the drain 7' at the bottom of the outer tub 3 '. During dehydration, the driving device 5' drives the inner tub 2 'to rotate at high speed, Under the action of centrifugal force, the moisture is discharged from the dehydration holes 21 'on the side wall of the inner tub 2' and the drain holes 22 'on the bottom to the outer tub 3', and then discharged out of the washing machine through the drainage port 7 'and the drainage pipe 9'.
由于现有的波轮式洗衣机，洗衣时，内桶与外桶的侧壁之间都需充满水，而内外桶之间的这部分水不参与洗涤，真正参与洗涤的水仅是内桶中的那部分，这使得水资源浪费较大，另外，内外桶之间过多的水也会降低洗涤液中洗涤剂/洗衣粉的浓度。Due to the existing pulsator type washing machine, when washing, both the inner and outer side walls need to be filled with water, and this part of the water between the inner and outer buckets does not participate in washing. The water that is actually involved in washing is only the one in the inner bucket. In part, this causes a large waste of water resources. In addition, too much water between the inner and outer buckets will also reduce the concentration of detergent / washing powder in the washing liquid.
很多厂家对上述缺陷作出改进，推出一种节水洗衣机，即内桶的桶壁上没有甩水用的漏空小孔，将洗涤、漂洗用水全部集中在无孔内桶中，使其既是盛水洗涤桶，又是离心脱水桶(也称为无孔内桶)。无孔节水洗衣机的外桶其实只是一个承担汇集无孔内桶在脱水时甩出水的通 道，排水时，提高内桶转速利用离心力，桶内的水沿内桶壁上升，从内桶上部平衡环下方的排水孔排出；或者是内桶下部设有可控开闭的排水口，从该排水口排出大部分水；离心脱水时，无孔内桶高速旋转，衣物中残留的水在离心力的作用下沿着无孔内桶的桶壁向上，通过排水孔甩入外桶，经外桶底的排水口及排水管排出。由于节省了传统洗衣机内外桶“夹层”中的水，节水效果平均可达50％以上。Many manufacturers have improved the above-mentioned defects, and introduced a water-saving washing machine, that is, there are no empty holes in the inner wall of the bucket for throwing water, and all the washing and rinsing water is concentrated in the non-porous inner bucket, so that it is used for washing. The barrel is also a centrifugal dehydration barrel (also called a non-porous inner barrel). The outer bucket of the non-porous water-saving washing machine is actually just a channel for collecting the non-porous inner bucket to throw water during dehydration. When draining, the inner bucket speed is increased by using centrifugal force. The water in the bucket rises along the inner bucket wall and drains water from the upper ring of the inner bucket. Holes can be discharged; or a drain opening with a controlled opening and closing can be provided at the lower part of the inner bucket to discharge most of the water; during centrifugal dehydration, the non-porous inner bucket rotates at high speed, and the residual water in the clothes moves along the non-porous under the action of centrifugal force The inner wall of the inner barrel is upward, and is thrown into the outer barrel through the drainage hole, and is discharged through the drainage outlet and the drainage pipe at the bottom of the outer barrel. Since the water in the "interlayer" of the inner and outer tubs of the conventional washing machine is saved, the water-saving effect can reach more than 50% on average.
但是，该节水洗衣机大多将内桶上部的排水孔设于内桶壁上，由于排水孔数量较少，否则，内桶强度变差，排水孔的总面积较小，排水量有限，在排脱水时，高速转动的离心力使得大部分的水超过排水孔所在高度，最终该部分水落下留存在内桶中，导致衣物内残留水较多，脱水效果很差。有些厂家作出一些改进，如申请号为CN200820003576.3和CN201020691475.7的中国专利公开的一种节水洗衣机内桶及排水孔的结构。However, most of the water-saving washing machines have drainage holes in the upper part of the inner tub on the wall of the inner tub. Because the number of drainage holes is small, otherwise the strength of the inner tub becomes poor, the total area of the drainage holes is small, and the drainage capacity is limited. The centrifugal force of the rotation caused most of the water to exceed the height of the drainage hole. Eventually, this part of the water fell and remained in the inner tub, resulting in more residual water in the clothes and a poor dehydration effect. Some manufacturers have made some improvements, such as the structure of a bucket and a drainage hole of a water-saving washing machine disclosed in Chinese patent applications CN200820003576.3 and CN201020691475.7.
上述结构虽然利用了平衡环配合内桶构成新的排水结构，使得上升的水能够直接排出，但是，在脱水过程，内桶高速转动，内桶中的衣物脱水沿桶壁向上爬升，会从平衡环与内桶之间的安装缝隙中溅出，溅射到外桶外部，造成安全隐患。Although the above structure uses a balance ring to cooperate with the inner bucket to form a new drainage structure, so that the rising water can be discharged directly, during the dehydration process, the inner bucket rotates at high speed, and the laundry in the inner bucket dewaters and climbs up along the wall of the bucket. Spills from the installation gap between them, and splashed to the outside of the outer barrel, posing a safety hazard.
有鉴于此特提出本发明。In view of this, the present invention is proposed.

现有技术中，波轮式洗衣机洗衣时，内桶与外桶的侧壁之间都需充满水，而内外桶之间的这部分水不参与洗涤，真正参与洗涤的水仅是内桶中的那部分，这使得水资源浪费较大，另外，内外桶之间过多的水也会降低洗涤液中洗涤剂/洗衣粉的浓度，很多厂家对上述缺陷作出改进，推出一种节水洗衣机，即内桶的桶壁上没有甩水用的漏空小孔，将洗涤、漂洗用水全部集中在无孔内桶中，使其既是盛水洗涤桶，又是离心脱水桶(也称为无孔内桶)。无孔节水洗衣机的外桶其实只是一个承担汇集无孔内桶在脱水时甩出水的接水装置，排水时，提高内桶转速，在离心力作用下桶内的水沿内桶壁上升，从内桶上部平衡环下方的出水口排出；或者是内桶下部设有可控开闭的排水口，从该排水口排出大部分水；脱水时，无孔内桶高速旋转，衣物中残留的水在离心力的作用下沿着无孔内桶的桶壁向上，通过出水口甩出至外部的外桶，经外桶底的排水口及排水管排出。由于节省了传统洗衣机内外桶“夹层”中的水，节水效果平均可达50％以上。In the prior art, when a pulsator type washing machine washes, water must be filled between the inner and outer side walls of the bucket, and this part of the water between the inner and outer buckets does not participate in washing. In part, this causes a large waste of water resources. In addition, too much water between the inner and outer buckets will also reduce the concentration of detergent / washing powder in the washing liquid. Many manufacturers have improved the above defects and introduced a water-saving washing machine, that is, The inner wall of the inner barrel does not have empty holes for throwing water. All washing and rinsing water is concentrated in the non-perforated inner barrel, so that it is both a water-containing washing barrel and a centrifugal dehydration barrel (also referred to as a non-porous inner barrel). The outer bucket of the non-porous water-saving washing machine is actually a water receiving device that collects the non-porous inner bucket to throw out water during dehydration. When draining, the rotation speed of the inner bucket is increased. Under the action of centrifugal force, the water in the bucket rises along the inner bucket wall and is balanced from the upper part of the inner bucket. The water outlet under the ring is discharged; or a drain opening with a controlled opening and closing is provided at the lower part of the inner tub to discharge most of the water; during dehydration, the non-porous inner tub rotates at a high speed, and the residual water in the clothing runs along the centrifugal force. The barrel wall facing the non-perforated inner barrel is upward, and is thrown out to the outer barrel through the water outlet, and is discharged through the drain outlet and drain pipe at the bottom of the outer barrel. Since the water in the "interlayer" of the inner and outer tubs of the conventional washing machine is saved, the water-saving effect can reach more than 50% on average.
但是，该节水洗衣机大多将内桶上部的出水口设于内桶壁上，由于出水口数量较少，否则，内桶强度变差，出水口的总面积较小，排水量有限，在排脱水时，高速转动的离心力使得大部分的水超过出水口所在高度，最终该部分水落下留存在内桶中，导致衣物内残留水较多，脱水效果很差，针对上述所述的技术问题，本发明提出如下技术方案。However, most of the water-saving washing machines have water outlets in the upper part of the inner barrel on the wall of the inner barrel. Because the number of water outlets is small, otherwise, the strength of the inner barrel is deteriorated, the total area of the water outlet is small, and the drainage capacity is limited. The centrifugal force of rotation makes most of the water exceed the height of the water outlet. Eventually, this part of water falls into the inner bucket, resulting in more residual water in the clothes and poor dehydration effect. In view of the technical problems described above, the present invention proposes the following technology Program.

The balance ring 1 is installed at the upper opening of the barrel body 2, and a circumferential direction is provided on the upper peripheral wall of the barrel body 2. An inner protruding support portion 3 is provided on the outer peripheral wall of the balance ring 1 with an overlap portion 4 overlapping the support portion 3. A seal 5 is sandwiched between the support portion 3 and the overlap portion 4. The seal 5 is clamped between the inner tub and the balance ring 1, and the support portion 3 is squeezed by the overlap portion 4 to realize the seal between the balance ring 1 and the inner barrel, thereby preventing water from flowing back from the gap between the balance ring 1 and the inner barrel to the inner barrel. Medium, resulting in too much residual water in the clothes, which leads to a problem of poor dehydration effect. The sealing member 5 may be a sealing ring, such as a rubber sealing ring, or a sealing structure such as a sealant.
进一步地，本发明提供一种洗衣机内桶，具有上述所述的平衡环安装结构，具体来说，在上述支撑部3下方设置有出水口7，脱水时，桶内水受离心力向上爬升由该出水口7直接或间接向桶外部导水，支撑部3有效的保证了脱水时，水从出水口7流出，而不会向上爬升至支撑部上方的平衡环1与内桶之间的缝隙使得脱水结束又回流至内桶中，导致衣物内残留水过多，进而导致脱水效果差的问题。Further, the present invention provides an inner tub of a washing machine, which has the above-mentioned balance ring mounting structure. Specifically, a water outlet 7 is provided below the support portion 3, and the water in the tub is decelerated by centrifugal force during dehydration. The water outlet 7 directly or indirectly conducts water to the outside of the bucket, and the support portion 3 effectively ensures that when the water is dehydrated, the water flows out of the water outlet 7 without climbing up to the gap between the balance ring 1 and the inner barrel above the support portion, so that the dehydration ends. Returning to the inner tub again, resulting in too much residual water in the clothes, which led to a problem of poor dehydration effect.
更进一步地，一种洗衣机，包括外壳，具有上述所述的洗衣机的内桶，内桶的外部设有接水的接水装置(图中未示出)，脱水时，由内桶出水口7导出的水被接水装置收集后排出洗衣机。Still further, a washing machine includes a casing having the inner tub of the above-mentioned washing machine, and a water receiving device (not shown in the figure) for receiving water is provided on the outside of the inner tub. After being collected by the water receiving device, it is discharged from the washing machine.
所述的接水装置通过减振单元与洗衣机的外壳连接(图中未示出)，接水装置支撑内桶，不仅使得内桶可转动的设置在外壳内，也能够收集内桶排出的洗涤水，由与接水装置连通的排水单元排出至洗衣机外部。该减振单元可采用现有波轮洗衣机的吊杆减振结构，也可采用安装在接水装置下方向上支撑的阻尼减振结构，或者采用上述的组合。The water receiving device is connected to the casing of the washing machine through a vibration damping unit (not shown in the figure). The water receiving device supports the inner tub, which not only enables the inner tub to be rotatably disposed in the outer casing, but also collects washing water discharged from the inner tub. The drainage unit communicating with the water receiving device is discharged to the outside of the washing machine. The vibration damping unit may adopt a boom vibration damping structure of an existing pulsator washing machine, a damping vibration damping structure installed under the water receiving device and supporting upwards, or a combination thereof.
该接水装置为桶状结构、盘状结构，或者由支撑在内桶下方的支撑板和设置在支撑板上方的环形凸筋构成；还可以采用现有洗衣机的外桶或低于内桶上端沿的凹槽结构。The water receiving device is a bucket-like structure, a disc-like structure, or is composed of a support plate supported below the inner tub and an annular rib provided above the support plate; an outer tub of the existing washing machine or a lower edge of the upper end of the inner tub may also be used Groove structure.
脱水时，内桶中的水可由出水口直接甩出至接水装置内，也可在内桶周壁包括内桶周壁内部或外部设有自上向下的导水管道，导水管道与出水口相通，向下导水至接水装置内。During dehydration, the water in the inner bucket can be directly thrown out of the water outlet into the water receiving device, or the inner wall of the inner bucket, including the inner wall of the inner bucket or the outside, is provided with a top-down water-conducting pipe. The water-conducting pipe communicates with the water outlet, and Drain water into the water receiving device.
