Generally speaking, a washing machine includes: a tub for containing washing water; a rotating tub rotationally installed in the tub; impellers rotationally installed at a bottom of the rotating tub; a motor and a clutch which are configured to rotate the rotating tub and the impellers. When the rotating tub and the impellers rotate in a state in which clothing and detergents are put into the rotating tub, the impellers agitate washing water together with the clothing put into the rotating tub, thereby removing stains from the clothing.
- In order to increase the washing capacity of the washing machine, a larger rotating tub is required, that is, a height or diameter of the rotating tub needs to be increased. If the rotating tub is larger, an accommodating tub and a machine shell which are used for accommodating the rotating tub also need to be enlarged as the rotating tub is enlarged.
- The enlargement of the machine shell corresponding to the appearance of the washing machine is limited by the space of an area where the washing machine is installed. General users have a limited space for the washing machine in the home, so that it is not realistic to enlarge the washing machine shell to increase the capacity of the washing tub.

- As shown in
FIGS. 1-6 , a washing machine of the embodiment includes awashing tub 200 for containing water during a washing process and awater collecting device 500 for collecting drain water from the washing tub, wherein thewater collecting device 500 includes awater collecting cavity 503. - The
washing tub 200 of the washing machine in the embodiment is used as a water containing tub, no outer tub is arranged outside thewashing tub 200, only thewater collecting device 500 is arranged at a bottom of thewashing tub 200. Thus washing water in the washing tub is discharged to thewater collecting device 500 and then discharged, and therefore thewater collecting device 500 is provided with thewater collecting cavity 503 to achieve a function of temporarily storing water. - The washing tub of the washing machine in the embodiment is used as the water containing tub, so that the washing tub adopts a “non-porous washing tub” design, meanwhile, an outer tub is omitted and replaced by the water collecting device which only collects and discharges drain water from the washing tub, and therefore the washing machine of the embodiment has the following technical effects.
- 1. The capacity of the washing tub can be increased under the condition that a volume of a shell remains unchanged, and thus a volume expansion effect of the washing machine is achieved.
- 2. Water only exists in the washing tub in the washing process, which avoids the problem of “dirt remaining” on an inner wall of an outer tub and the outer wall of the washing tub caused by water stored between an inner tub and an outer tub of a traditional washing machine, and a better washing effect is achieved.
- 3. The outer tub is omitted, and the washing tub is used as the water containing tub, so that no water is stored between the inner tub and the outer tub during the washing process, the washing water consumption is reduced, and washing water is saved.
- Due to the volume expansion of the washing machine, water is discharged from an opening of a water channel on the washing tub in the dehydration stage, as the outer tub is omitted, water discharged from the water channel enters the water collecting cavity of the water collecting device. Due to the volume expansion demand, a height of the water collecting device is limited, a water level in the water collecting cavity is at a certain height, when the washing tub rotates at a high speed for dehydration, the water level increases, and water flow attaches to the inner wall of the water collecting cavity. If water cannot be discharged in time, water splashes or rises to overflow out of a water drainage channel. Therefore, the embodiment aims to increase the volume in the water collecting cavity as much as possible under the condition that that the height of the water collecting device remains unchanged, so as to avoid the problem of water splashing or overflow in the water collecting device.
- Therefore, the
water collecting cavity 503 of the embodiment is internally provided with a volume expansion structure for expanding the volume. Due to the volume expansion structure, thewater collecting cavity 503 is outward expanded as much as possible to achieve the purpose of volume expansion under the condition of ensuring that the height of the water collecting device remains unchanged, so as to avoid the problem of water splashing or overflow in the water collecting device. - Further, a bottom wall of the
water collecting cavity 503 in the embodiment includes abottom wall body 505 located in the middle and a concavewater collecting groove 502 located on the outer periphery of thebottom wall body 505, thewater collecting device 500 includes adrainage port 504 communicating with the water collecting groove, and the volume expansion structure is located on a side wall, close to thebottom wall body 505, of thewater collecting groove 502, and is used for expanding a volume of thewater collecting groove 502. - The
water collecting groove 502 of the embodiment increases a depth of partial of the water collecting cavity, and meanwhile, outlet ends of drainage channels on the washing tub extend into thewater collecting groove 502 of thewater collecting device 500, in this way, even if the washing tub rotates at a high speed for dehydration, discharged water directly enters the deeperwater collecting groove 502, so that water splashing or overflow is avoided. - It can be seen that since drain water of the washing tub is directly discharged into the
water collecting groove 502 of the water collecting device, water splashing or overflow is avoided by arranging the volume expansion structure on thewater collecting groove 502 for expanding the volume of thewater collecting groove 502 in the present disclosure without overall deepening, and thus the height and strength of the water collecting device are ensured. - As an implementation of the embodiment, the volume expansion structure includes a first
volume expansion part 512, and the firstvolume expansion part 512 is formed by the side wall, close to the bottom wall body, of thewater collecting groove 502 extending obliquely toward the bottom wall body, so that the volume of thewater collecting groove 502 is increased. - In the embodiment, an arrangement mode and an inclination angle of the first
volume expansion part 512 need to ensure the overall height and strength of the water collecting device. - Specifically, the side wall, close to the
bottom wall body 505, of thewater collecting groove 502 extends obliquely toward thebottom wall body 505 in an entire circumferential direction to form a full circle of the firstvolume expansion part 512; or, - the side wall, close to the
bottom wall body 505, of thewater collecting groove 502 partially extends obliquely toward thebottom wall body 505 to form a plurality of firstvolume expansion parts 512 distributed along the outer periphery of thebottom wall body 505. - In the embodiment, inclination angles of the first
volume expansion part 512 at positions in the entire circumferential direction of the bottom wall body are the same, and therefore the volume of thewater collecting groove 502 can be expanded as much as possible. - Alternatively, the inclination angles of the first
volume expansion part 512 at the positions in the entire circumferential direction of the bottom wall body gradually increase, thus, a transition structure is formed between the side wall of the water collecting groove and thebottom wall body 505, a certain water guiding effect is achieved, and water is guided from the bottom wall body to thewater collecting groove 502. - As an implementation mode of the embodiment, the volume expansion structure includes a second
volume expansion part 513, and the secondvolume expansion part 513 is formed by recessing the side wall, close to thebottom wall body 505, of thewater collecting groove 502 toward thebottom wall body 505. - Further, the second
volume expansion part 513 includes a plurality of inward recesses distributed around the outer periphery of the bottom wall body and formed by partially recessing the side wall, close to the bottom wall body, of the water collecting groove toward the bottom wall body, wherein - at least one inward recess corresponds to the position of the drainage port.
- Further, the inward recess corresponding to the drainage port is larger than the other inward recesses.
