Description

洗衣机washing machine 技术领域Technical field
本发明属于洗涤领域，具体地说，涉及一种洗衣机。The invention belongs to the field of washing, and in particular to a washing machine.
背景技术Background technique
传统的全自动波轮洗衣机一般包括内桶、外桶、减振部件和动力***组成，在洗衣和脱水时，内桶相对外桶转动，使衣物与洗涤水产生作用，达到洗净衣物或脱水的目的，其中，外桶安装在内桶的外部，为内桶提供支撑，外桶作为盛水桶，内桶侧壁上均布着排水孔，使内外两桶相通。在洗衣的过程中，衣物放置在内桶中，两桶水位一样高，但外桶不与衣物接触，现有洗衣机的外桶相对内桶的体积较大，造成内外桶之间的洗涤水存量较多，两桶之间的洗涤液不能充分利用，既增加了洗衣的用水量，又降低了洗涤时洗涤液的浓度，而且也造成洗衣机整体的体积偏大。另外，使用一段时间后，外桶内壁和内桶外壁上会附着污垢，甚至会发霉，进而会污染所洗涤的衣物，且桶壁很难清洁。The conventional fully automatic pulsator washing machine generally comprises an inner barrel, an outer barrel, a vibration damping component and a power system. During the washing and dehydration, the inner barrel rotates relative to the outer barrel to make the clothes and the washing water function to achieve the purpose of washing the clothes or dehydrating. The outer tub is installed on the outside of the inner tub to provide support for the inner tub, and the outer tub is used as a water tub, and the inner side wall of the inner bucket is provided with a drainage hole so that the inner and outer two barrels communicate with each other. In the process of washing, the clothes are placed in the inner tub, the water level of the two buckets is as high, but the outer tub is not in contact with the clothes, and the outer tub of the existing washing machine has a larger volume relative to the inner tub, resulting in more storage of washing water between the inner and outer buckets. The washing liquid between the two barrels cannot be fully utilized, which increases the water consumption of the washing machine, reduces the concentration of the washing liquid during washing, and also causes the overall volume of the washing machine to be large. In addition, after a period of use, dirt may be attached to the inner wall of the outer tub and the outer wall of the inner tub, and even mold may be caused, which may contaminate the laundry and the wall of the tub is difficult to clean.
针对该情况，有些厂商做出了改进，为了节省水资源，洗衣机越来越多的采用无孔内桶的方式，如图1所示，使内外桶分离，只用内桶2’储水，而外桶1’无水。在内桶2’侧壁靠上端开设有排水孔3’，这样，当洗衣机脱水时，水由于离心力的作用被甩在内桶内壁上，并沿内桶内壁向上移动，从内桶2’上端的排水孔3’排出，这样提高了洗衣机节水的效果，并节约了洗涤剂的用量。In response to this situation, some manufacturers have made improvements. In order to save water resources, washing machines are increasingly using non-porous inner barrels. As shown in Figure 1, the inner and outer barrels are separated, and only the inner barrel 2' is used for water storage. Bucket 1' is anhydrous. A drain hole 3' is opened at the upper end of the side wall of the inner tub 2', so that when the washing machine is dehydrated, the water is smashed on the inner wall of the inner tub due to the centrifugal force, and moves upward along the inner wall of the inner tub, and the drain hole 3 from the upper end of the inner tub 2' 'Exhaust, this improves the water saving effect of the washing machine and saves the amount of detergent.
但是，在上述方案中存在以下问题，由于洗衣机脱水时高速旋转，衣物中的水通过内桶2’侧壁上的排水孔3’甩出，直接打在外桶1’侧壁上，容易四处飞溅，外桶内壁上长期有水，还是容易滋生细菌，不利于环保。However, in the above solution, there is the following problem. Since the washing machine spins at a high speed during dehydration, the water in the laundry is thrown out through the drain hole 3' on the side wall of the inner tub 2', and is directly hit on the side wall of the outer tub 1', so that it is easy to splash around. There is long-term water on the inner wall of the outer tub, which is easy to breed bacteria, which is not conducive to environmental protection.
申请号为CN99230455.5的中国专利公开了一种单桶式的节水型洗衣机，洗涤桶的桶口处设有一集水装置，集水装置的集水口沿洗涤桶围罩在其的桶口处，集水装置位于桶口处的集水腔与若干排水管相连，它们沿洗涤桶的外壁自上而下对称布置，甩干时，集水装置收集因高速旋转的离心水流并将其向下引导排掉，该结构虽然省去了外桶，但在其洗衣机脱水时，由于洗涤水都先进入集水装置，集水装置为一环形结构，内部填充的洗涤水向下排水速度不同，破坏洗涤桶高速旋转的平衡；另外，洗涤水进入集水装置后引导至洗涤桶下部向中心汇集排出，不利于排水，使得在离心力的作用下集中在集水腔内难以排出，造成洗涤水集中在 洗涤桶的上端，增大洗涤桶上部的重量，更进一步破坏平衡，尤其是洗涤桶残余的水较多时，大部分洗涤水集中在集水腔内不被排出，提高洗涤桶和外桶的总体重心，产生了极大的震动噪音，也增大了脱水电机的工作载荷，易于损坏电机。The Chinese patent application No. CN99230455.5 discloses a single-barrel type water-saving washing machine, and a water collecting device is arranged at the barrel mouth of the washing bucket, and the water collecting port of the water collecting device is covered around the barrel of the washing tub. Wherein, the water collecting device is located at the mouth of the bucket and is connected to a plurality of drain pipes. They are arranged symmetrically from top to bottom along the outer wall of the washing tub. When the tank is dry, the water collecting device collects the centrifugal water flowing due to the high speed and directs it to The lower guide is drained. Although the structure eliminates the outer tub, when the washing machine is dehydrated, since the washing water first enters the water collecting device, the water collecting device has a ring structure, and the internally filled washing water has a different drainage speed. Destroy the balance of the high-speed rotation of the washing tub; in addition, the washing water enters the water collecting device and is guided to the lower part of the washing tub to be collected and discharged to the center, which is not conducive to drainage, so that it is difficult to discharge in the collecting chamber under the action of centrifugal force, resulting in concentration of washing water. At the upper end of the washing tub, the weight of the upper part of the washing tub is increased, and the balance is further broken. Especially when the residual water of the washing tub is large, most of the washing water is concentrated in the collecting chamber and is not discharged. Out, the overall center of gravity of the washing tub and the outer tub is increased, and great vibration noise is generated, and the working load of the dehydrating motor is also increased, which is liable to damage the motor.
有鉴于此特提出本发明。The present invention has been made in view of the above.
