BACKGROUND
A washing machine is designed as a device for washing laundry through the use of electricity. Generally speaking, a washing machine includes: a tub for holding washing water; a rotating tub, rotatably mounted inside the tub; an impeller, rotatably mounted at the bottom of the rotating tub; a motor and a clutch, configured to drive the rotating tub and the impeller to rotate. When the rotating tub and the impeller rotate in a state in which laundry and a detergent are introduced into the rotating tub, the impeller agitates washing water together with laundry introduced into the rotating tub, thereby removing stains from laundry. In order to increase the washing capacity of a washing machine, a larger rotating tub is required, i.e. the height or diameter of the rotating tub needs to be increased. If the rotating tub has a larger size, the tub accommodating the rotating tub and a casing accommodating the tub also need to be increased as the rotating tub increases. While in the washing process of the conventional pulsator washing machine, the inner and outer tubs are communicated with each other, with water in both the inner and outer tubs, but only water in the inner tub is actually used for laundry washing, resulting in water wasting. Moreover, during long-term use, dirt accumulates between the inner tub and the outer tub, bacteria grow, and the water exchange process between the inner tub and the outer tub causes secondary contamination to the laundry, so that draining of the washing water inside the washing tub in time and avoiding contamination of the inner space of the washing machine become problems to be solved urgently.

The driving device is connected with the sealing disc and the non-porous inner tub, and is used for driving the non-porous inner tub and the sealing disc to rotate and driving the sealing disc to rotate relative to the non-porous inner tub.

As shown in FIGS. 1 to 10, a washing tub 1 for a washing machine according to the present disclosure includes a body of the washing tub 1, wherein a dewatering port 3 is formed in the top of the tub wall of the washing tub 1 and is configured as an opening structure for guiding out washing water in the washing tub 1, a water guide structure 2 for guiding washing water in the washing tub 1 to a water receiving device 6 at the lower part of the washing tub 1 is arranged corresponding to the dewatering port 3, the water guide structure 2 is arranged on the tub wall of the washing tub 1 and communicated with the dewatering port 3. Due to the capacity enlargement of the washing machine, in the dewatering stage, water is drained from a dewatering port into a water channel. According to the present disclosure, the dewatering port 3 of the washing tub 1 is formed in the tub wall of the washing tub 1, and simultaneously the water guide structure 2 is communicated with the dewatering port 3, the flowing trend of the water flow during dewatering of the washing tub 1 is effectively utilized, and the energy consumption is reduced while the function is guaranteed.
As shown in FIGS. 1 and 2, in order to enlarge the capacity of the washing tub 1 to accommodate more laundry in the process of washing operation, an outer tub originally arranged outside the washing tub 1 is omitted. Without the outer tub, water drained from the water channel enters a drainage trough at the bottom, the capacity of the washing tub 1 is required to be enlarged, and the height of the drainage trough is limited. The water level in the drainage trough is of a certain height, when the inner tub rotates at a high speed for dewatering, the shape structure of the water channel directly influences the water splashing degree. Therefore, the water guide structure 2 is arranged on the outer wall of the washing tub 1. Meanwhile, the water guide structure 2 mainly includes an arc-shaped outer wall 201 arranged at the end far away from the washing tub 1 and an inner wall 202 arranged at the end near the washing tub 1. The inner wall 202 is closer to the washing tub 1, the radius of the outer wall 201 is smaller than the radius of the inner wall 202, the radius of the outer wall 201 is smaller than the radius of the inner wall 202 of the washing tub 1, i.e. the radius of the outer wall 201 is smaller than the radius of the washing tub 1. By setting the outer wall 201 of the water guide structure 2 in a large circular arc shape, the contact area between the water guide structure 2 and water during dewatering is reduced, it is ensured that washing water can be drained from the water guide structure 2 more quickly. In order to prevent washing water from overflowing via the gap between the dewatering port 3 and the water guide structure 2 during washing and dewatering operations of the washing tub 1, a sealing structure is arranged between the tub wall of the washing tub 1 and the water guide structure 2, and the sealing structure can effectively prevent washing water from splashing via the gap between the tub wall of the washing tub 1 and the water guide structure 2.
As shown in FIGS. 1 to 5, the washing tub 1 according to the present disclosure is configured, during washing process, as a tub body for holding washing water. The portion, located below the dewatering port 3, of the tub wall of the washing tub 1 is impermeable, which guarantees that the washing tub 1 is in a non-porous state. Due to this arrangement, the structure of the outer tub is omitted, an inner tub is used as a main body for holding laundry and washing water, and the capacity of the washing tub 1 is increased under the condition that the overall washing machine capacity does not change or changes very little, a capacity enlargement effect of the washing machine is achieved. A conventional washing machine requires to be provided with an outer tub, and the corresponding washing and dewatering process can be done by cooperating use of the outer tub with the inner tub. Thus, stains may remain between the outer tub and the inner tub, and it is disadvantageous to health after long-time use of the washing machine. Water is only stored in the washing tub 1 during washing process according to the present disclosure, so that the problem of “keeping dirt” of the inner wall 202 of the outer tub and the outer wall of the washing tub 1 caused by water storage between the inner tub and the outer tub of a conventional washing machine is solved, and a better washing effect is achieved. Meanwhile, the outer tub is omitted and the washing tub 1 is used as the water holding tub, so that no water is stored between the inner tub and the outer tub during washing, thereby reducing the amount of washing water and saving washing water.
Further, according to the present disclosure, the water guide structure 2 is embedded in the outer wall of the washing tub 1, such arrangement improves the service life of the washing tub 1, and also facilitates maintenance and replacement. Preferably, the water guide structure 2 and the outer wall of the washing tub 1 form a smooth transition curved surface, and the smooth transition curved surface can effectively reduce wind resistance, reduce energy consumption and improve washing efficiency when the washing tub 1 rotates at a high speed.
As shown in FIGS. 4 and 5, in order to further guarantee the effect of drainage, the water guide structure 2 according to the present disclosure further includes a first water guide portion 4 which is closely attached to the outer side of the tub wall of the washing tub 1, the outer wall 201 of the first water guide portion 4 cooperates with the outer wall of the washing tub 1, i.e. the inner wall 202 of the first water guide portion 4, to form a water guide chamber structure for guiding washing water out of the washing tub 1. The benefit of such arrangement is that when the washing machine is in dewatering operation, in a high-speed rotation state of the washing tub 1, if there are too many constituent parts of the washing tub 1, during the rotation, vibration will be generated, and further noise is generated and the user's experience and sense will be affected to a certain degree. The water guide structure 2 cooperates with the outer wall of the washing tub 1 to form a water guide chamber, thus omitting the procedure of secondary processing and improving the service life of the washing tub 1 and improving the resistance to vibration noise of the washing machine at the same time.
As shown in FIG. 8, in order to prevent washing water from overflowing via the dewatering port 3 and the gap of the water guide structure 2 during washing and dewatering operations of the washing tub 1, a sealing structure 9 is arranged between the tub wall of the washing tub 1 and the water guide structure 2. And the sealing structure 9 can effectively prevent washing water from splashing via the gap between the tub wall of the washing tub 1 and the water guide structure 2.
At the same time, the water guide structure 2 also includes a second water guide portion 5 communicated with a water outlet end of the first water guide portion 4. The second water guide portion 5 guides washing water to a water receiving device 6 below the washing tub 1. Since the washing tub 1 is in a high-speed rotation state in the dewatering operation, in order to prevent washing water from flowing back into the washing tub 1 from the water guide structure 2 in the high-speed rotation state of the washing tub 1, the distance between the outer wall 201 of the first water guide portion 4 and the axis of the washing tub 1 is set to show a gradual change trend in the direction from the top of the washing tub 1 to the bottom of the washing tub 1, and the distance between the outer wall 201 of the second water guide portion 5 and the axis of the washing tub 1 is set to show a gradual change trend in the direction from the top of the washing tub 1 to the bottom of the washing tub 1. More preferably, the distance between the first water guide portion 4 and the axis of the washing tub 1 changes in a progressive increase trend; the distance between the second water guide portion 5 and the axis of the washing tub 1 changes in a progressive decrease trend. The washing tub of the present disclosure is provided with a multi-section water guide structure 2 exploiting the flowing trend of water in the washing tub 1 rotating at a high speed, thus avoiding the back flow of the water flow during draining, and guaranteeing the concentrated draining of the water flow during draining.
A section of the water guide structure 2 embedded in the washing tub 1 is designed as a wall structure, which allows the water inside the water guide structure 2 to leave the water guide chamber and enter a larger space inside the water receiving device 6 at the lower part of the washing tub 1 as early as possible, thus avoiding excessive water inside the water guide structure 2 during dewatering, resulting in hazards such as increased noise and vibration. This single wall structure retains the outer side portion and when water presses against the outer wall 201 under the action of centrifugal force, the single wall can block the water, thus reducing the possibility that water splashes out of the water guide structure 2. An arc shape of the single wall is consistent with the dewatering direction, which reduces the shearing force and stressed area applied to the water, thereby reducing the risk of splashing water. In order to maximize the capacity of the inner tub, during dewatering, the water is attached to the outer wall of the water channel under the action of centrifugal force, in order to guarantee the rapid outflow of the water and reduce the vibration and noise generated by the accumulated water, the outer wall of the water channel is in large-arc transition and cannot have noticeable corner transitions.
