Description

一种洗衣机Washing machine 技术领域Technical field
本发明属于洗衣机领域，具体地说，涉及一种洗衣机。The invention belongs to the field of washing machines, and in particular to a washing machine.
背景技术Background technique
洗衣机被设计成通过使用电来洗涤衣物的装置，一般来说，洗衣机包括：桶，用于容纳洗涤水；旋转桶，可旋转地安装在桶的内部；波轮，可旋转地安装在旋转桶的底部；电机和离合器，被构造成使旋转桶和波轮旋转。当旋转桶和波轮在衣物和洗涤剂被引入到旋转桶中的状态下旋转时，波轮与被引入到旋转桶中的衣物一起搅动洗涤水，从而从衣物去除污渍。The washing machine is designed as a device for washing laundry by using electricity. Generally, the washing machine includes: a tub for accommodating washing water; a rotating tub rotatably installed inside the tub; and a pulsator rotatably mounted in the rotating tub The bottom; the motor and clutch are configured to rotate the rotating barrel and the pulsator. When the rotating tub and the pulsator are rotated in a state where the laundry and the detergent are introduced into the rotating tub, the pulsator agitates the washing water together with the laundry introduced into the rotating tub, thereby removing the stain from the laundry.
为了增加洗衣机的洗涤容量，需要更大的旋转桶，即需要增加旋转桶的高度或直径。如果旋转桶具有更大的尺寸，则容纳旋转桶的桶及容纳桶的机壳也需要随着旋转桶的增大而增大。与洗衣机的外观对应的机壳的增大受到安装洗衣机的区域的空间的限制，一般的用户家中用于方式洗衣机的位置有限，增加洗衣机机壳来达到增加洗衣桶容量的目的不够现实，如如何在不增加洗衣机的机壳的前提下，增加旋转桶的容量成为困扰设计者的一大难题。In order to increase the washing capacity of the washing machine, a larger rotating tub is required, that is, the height or diameter of the rotating tub needs to be increased. If the rotary tub has a larger size, the bucket accommodating the rotary tub and the cabinet accommodating the tub also need to increase as the rotary tub increases. The increase of the casing corresponding to the appearance of the washing machine is limited by the space of the area in which the washing machine is installed. The position of the washing machine for the general user's home is limited, and the purpose of increasing the size of the washing machine to increase the capacity of the washing tub is not realistic, such as how to Increasing the capacity of the rotating drum without increasing the casing of the washing machine becomes a major problem for the designer.
专利CN201610210904.6提供了本发明公开了一种无孔内桶洗衣机，涉及洗衣机技术领域，为在节水的前提下，解决由内桶上方排水时水容易飞溅，外桶滋生细菌的问题，且可以降低洗衣机成本而发明。一种无孔内桶洗衣机，包括内桶和外桶，所述内桶的桶口处设有集水环，所述集水环包括集水腔以及与所述集水腔连通的集水口和排水口，所述集水口朝向所述内桶内部，所述排水口朝向所述内桶和外桶之间的空隙，所述排水口连接有排水管，所述排水管向下延伸至所述外桶的底部，该结构实现了集水效果。但是由于外桶的外檐延伸至内桶以上，使得内桶很容易碰撞到外桶造成损伤，而且由于外檐的存在，不利于内桶容积的增加；另外，在内桶脱水过程中，高速旋转，甩出的水进入到外桶底，很容易飞溅出外桶，时间长了，飞溅出的洗涤水容易腐蚀箱体外壳，也容易引起电路的短路。Patent CN201610210904.6 provides a non-porous inner drum washing machine, relating to the technical field of washing machines, in order to solve the problem that water is easily splashed when the water is drained from above the inner tub, and the outer tub breeds bacteria under the premise of water saving, and can be reduced Invented by the cost of the washing machine. A non-perforated inner tub washing machine includes an inner tub and an outer tub, wherein the inner tub has a water collecting ring at the barrel mouth, and the water collecting ring includes a water collecting chamber and a water collecting port and a drain port communicating with the water collecting chamber. The water collecting port faces the inner tub, the drain port faces a gap between the inner tub and the outer tub, and the drain port is connected with a drain pipe, and the drain pipe extends downward to the bottom of the outer tub. This structure achieves the water collecting effect. However, since the outer raft of the outer tub extends above the inner tub, the inner tub easily collides with the outer tub to cause damage, and due to the presence of the outer cymbal, the volume of the inner tub is not increased; in addition, during the inner tub dehydration process, the high-speed rotation and the squeezing out The water enters the bottom of the outer tub, and it is easy to splash out of the outer tub. For a long time, the splashed washing water tends to corrode the outer casing of the casing, and it is easy to cause short circuit of the circuit.
有鉴于此特提出本发明。The present invention has been made in view of the above.

实施例一 Embodiment 1
如图1-5所示，本实施例提供一种洗衣机,包括箱体1、设置于箱体1内的内桶2、用于驱动所述内桶2转动的驱动装置3以及设置在内桶2底部的集水装置5，在洗涤/漂洗时所述的内桶2为盛水桶，所述内桶2的外壁上设有与内桶2连通的、用于排出内桶2甩出的水的脱水水道4，所述集水装置5包括具有上开口的集水腔501，集水腔501的底壁上具有凹部6，脱水水道4的出水端401向下延伸到凹部6内。As shown in FIG. 1-5, the embodiment provides a washing machine, including a box body 1, an inner tub 2 disposed in the cabinet 1, a driving device 3 for driving the inner tub 2 to rotate, and a bottom portion of the inner tub 2. The water collecting device 5 is a water tub when the washing/rinsing is performed, and the outer wall of the inner tub 2 is provided with a dewatering channel 4 communicating with the inner tub 2 for discharging water drawn from the inner tub 2, The water collecting device 5 includes a water collecting chamber 501 having an upper opening having a recess 6 on the bottom wall thereof, and the water outlet end 401 of the dewatering channel 4 extends downward into the recess 6.
本实施例的洗衣机没有外桶，内桶2可以作为盛水桶，也就是为仅在上部设有脱水孔、中部和下部无孔的内桶2。在内桶2的底部设置集水装置5，一方面当水从内桶2排出时，可以收集内桶2中排出的水，防止水溢出；另一方面，集水装置5对内桶2的扩容不具有限制作用，为内桶2的扩容提供充裕的空间。The washing machine of the present embodiment has no outer tub, and the inner tub 2 can serve as a tub, that is, an inner tub 2 having a dewatering hole, a middle portion, and a bottom portion having no holes only in the upper portion. A water collecting device 5 is disposed at the bottom of the inner tub 2, and on the one hand, when water is discharged from the inner tub 2, water discharged from the inner tub 2 can be collected to prevent water from overflowing; on the other hand, the water collecting device 5 does not limit the expansion of the inner tub 2. The function provides ample space for the expansion of the inner tub 2.
在集水腔501的底壁上设置凹部6，脱水水道4的出水端401延伸***凹部6中，有利于水的收集和排出，还能够防止脱水排水时排出的水飞溅出集水腔501，防止溅出的水腐蚀箱体1，同时防止溅出的水引起电路短路，尤其适用于集水腔501侧壁较低时防止水的飞溅，同时达到最佳的扩容和防止溅水的效果。A recessed portion 6 is provided in the bottom wall of the water collecting chamber 501, and the water outlet end 401 of the dewatering water channel 4 is inserted into the recessed portion 6, which is advantageous for collecting and discharging water, and also prevents water discharged during dehydration and drainage from splashing out of the water collecting chamber 501. The splashed water is prevented from corroding the casing 1 while preventing the water from being splattered to cause short circuit of the circuit, and is particularly suitable for preventing water splashing when the side wall of the water collecting chamber 501 is low, and at the same time achieving optimal expansion and preventing splashing.
所述的凹部6可以由集水腔501的底壁向下凹陷形成，或者，也可以另外底壁上设置单独的件，如在集水腔501的底壁的上设置设有挡水筋502，挡水筋502与集水腔501的底壁共同形成凹部6。The recessed portion 6 may be recessed downwardly from the bottom wall of the water collecting chamber 501, or a separate member may be disposed on the bottom wall, for example, a water retaining rib 502 is disposed on the bottom wall of the water collecting chamber 501. The water retaining rib 502 forms a recess 6 together with the bottom wall of the water collecting chamber 501.
优选的方案，所述集水腔501的侧壁上端低于所述内桶2的桶底。In a preferred embodiment, the upper end of the side wall of the water collecting chamber 501 is lower than the bottom of the inner tub 2.
由于集水腔501的侧壁上端低于所述内桶2的桶底，可以使集水腔501整***于内桶2的桶底以下，使集水腔501的侧壁不具有位于内桶2和箱体1之间的结构，不用在内桶2和集水装置5之间设置一定的安全距离，防止内桶2碰撞到集水装置5造成损坏，同时也不用在集水装置5和箱体1之间再设置安全距离，因此仅设计内桶2与箱体1之间的安全距离即可，可以大大增加内桶2桶径，更好的实现内桶2的扩容。Since the upper end of the side wall of the water collecting chamber 501 is lower than the bottom of the inner tub 2, the water collecting chamber 501 can be entirely located below the bottom of the inner tub 2, so that the side wall of the water collecting chamber 501 does not have the inner tub 2 and the cabinet. The structure between 1 does not require a certain safety distance between the inner tub 2 and the water collecting device 5 to prevent the inner tub 2 from colliding with the water collecting device 5, and is not damaged between the water collecting device 5 and the tank 1. The safety distance is set, so only the safety distance between the inner tub 2 and the cabinet 1 can be designed, and the inner bucket 2 barrel diameter can be greatly increased, and the inner bucket 2 can be better expanded.
优选的方案，所述的集水装置5包括安装底板503和设置在安装底板503上的挡水筋502，所述安装底板503与挡水筋502围合形成具有上开口的集水腔501，所述挡水筋502的上端低于内桶2的桶底，所述的凹部6由安装底板503向下凹陷形成。Preferably, the water collecting device 5 includes a mounting bottom plate 503 and a water retaining rib 502 disposed on the mounting bottom plate 503. The mounting bottom plate 503 is enclosed with the water retaining rib 502 to form a water collecting cavity 501 having an upper opening. The upper end of the water retaining rib 502 is lower than the bottom of the inner tub 2, and the recess 6 is recessed downward by the mounting bottom plate 503.
通过设置安装底板503和挡水筋502，使二者围合形成集水腔501，两者可以一体成型，或者密封固定。凹部6可以在安装底板503上直接设置，凹陷形成，该结构简单，便于加工成型。By providing the mounting bottom plate 503 and the water retaining rib 502, the two are enclosed to form the water collecting chamber 501, and the two can be integrally formed or sealed. The recess 6 can be directly disposed on the mounting bottom plate 503, and the recess is formed. The structure is simple and convenient for processing.
进一步的方案，内桶2在水平方向的投影位于集水腔501在水平方向的投影的内部时，脱水水道4的出水端401可以向下竖直延伸或者弯折延伸，***凹部6中；优选向下竖直延伸，如此不需要计算弯折角度，加工简单，而且水流不受弯折阻挡，更流畅，更利于排水。Further, when the projection of the inner tub 2 in the horizontal direction is located inside the projection of the water collecting chamber 501 in the horizontal direction, the water outlet end 401 of the dewatering channel 4 may extend vertically downward or bend and be inserted into the recess 6; The bottom extends vertically, so that the bending angle is not required to be calculated, the processing is simple, and the water flow is not blocked by the bending, which is smoother and more favorable for drainage.
内桶2在水平方向的投影覆盖所述集水腔501在水平方向的投影时，脱水水道4的出水端401向内弯折，并延伸至凹部6中。此种方案的集水腔501的外径小于内桶2的外径，由 于脱水水道4设置在内桶2的外周壁上，因此需要向内弯折进入，可以经过多道弯折，***到凹部6中。When the projection of the inner tub 2 in the horizontal direction covers the projection of the water collecting chamber 501 in the horizontal direction, the water outlet end 401 of the dewatering channel 4 is bent inward and extends into the recess 6. The outer diameter of the water collecting chamber 501 of this type is smaller than the outer diameter of the inner tub 2. Since the dewatering channel 4 is disposed on the outer peripheral wall of the inner tub 2, it needs to be bent inwardly and can be inserted into the recess 6 through multiple bends. in.
凹部6可以通过管路11与洗衣机的排水管8连通，直接通过排水管8及时排出凹部6中的水，防止水从上部溅出；也可以充分利用集水腔501的底壁，集水腔501的底部设有排水口7；集水腔501的部分底壁低于凹部6的底部，凹部6中的水可以直接汇集到集水腔501中，然后经过排水口7排出。此种方式可以不用再另行设置管路11。The recessed portion 6 can communicate with the drain pipe 8 of the washing machine through the pipeline 11 and directly discharge the water in the recessed portion 6 through the drain pipe 8 to prevent water from splashing from the upper portion; and the bottom wall of the water collecting chamber 501 can be fully utilized, and the water collecting chamber can be fully utilized. The bottom of the 501 is provided with a drain port 7; a part of the bottom wall of the water collecting chamber 501 is lower than the bottom of the recess 6, and the water in the recess 6 can be directly collected into the water collecting chamber 501 and then discharged through the drain port 7. In this way, it is no longer necessary to separately provide the line 11.
实施例二 Embodiment 2
如图1-3所示，本实施例为实施例一的进一步的限定，本实施例的凹部6由集水腔501的底壁向下凹陷形成；所述的凹部6为由集水腔501的底壁沿周向向下凹陷一圈形成的环形凹槽601，脱水水道4的出水端401向下延伸至环形凹槽601的开口内。As shown in FIG. 1-3, the embodiment is further defined by the first embodiment. The recess 6 of the embodiment is formed by recessing the bottom wall of the water collecting chamber 501. The recess 6 is formed by the water collecting chamber 501. The bottom wall is recessed downwardly in a circumferential direction to form an annular groove 601, and the water outlet end 401 of the dewatering channel 4 extends downward into the opening of the annular groove 601.
