The present disclosure relates to a field of household appliances, and more particularly to a washing machine.
In a conventional impeller washing machine, water levels of inner tub and outer tub are the same during the washing, such that the inner tub and the outer tub need to be filled with washing water, thus a relatively large amount of washing water is required. However, the water between the inner tub and the outer tub does not involve in the washing, and only the water in the inner tub actually involves in the washing, such that water resources are wasted. Furthermore, the excessive water between the inner tub and the outer tub will also reduce a concentration of detergent, such that a larger amount of detergent needs to be put in to achieve a good washing effect, which undoubtedly also causes a waste of the detergent.
In order to further improve water saving performance, a washing machine with a holeless inner tub exists in the related art, in which the inner tub is configured as a holeless stainless steel tub, such that a water level difference is formed between the inner tub and the outer tub, and the washing water can be saved. Meanwhile, this washing machine is provided with a water outlet passage above the inner tub, and the washing water flows upwardly along a wall of the inner tub and is discharged via the water outlet passage under the action of a centrifugal force during dehydration, thereby achieving a purpose of discharging the water.

The washing machine 100 according to a specific embodiment of the present disclosure will be described in detail in the following with reference to accompanying drawings
In combination with
The outer wall of the balance ring 4 defines the recess 103 recessed inwardly and extending in the axial direction of the balance ring 4, the recess 103 extends upwardly from the lower end surface of the balance ring 4 beyond the upper end surface of the washing tub 31, and the inner wall of the washing tub 31 and the recess 103 define the water outlet passage 101. The bottom wall of the recess 103 extends obliquely and outwardly in the direction from bottom to top.
The circumferential wall of the washing tub 31 is provided with the water leakage hole 104 communicating the interior of the washing tub 31 and the exterior of the washing tub 31, and the water leakage hole 104 is located below the central area 102 and adjacent to the lower end of the washing tub 31. The upper end of the tub bottom 32 is fitted in the lower end of the washing tub 31, the water leakage hole 104 of the washing tub 31 is covered by the part of the tub bottom 32 fitted in the washing tub 31, and the water leakage hole 104 may be communicated with the interior of the washing tub 31.
Additionally, the washing tub 31 is also provided with the tub bottom positioning hole 105, the tub bottom mounting hole 106, the cover plate mounting hole 107 and the mold process positioning hole. Those holes are only intended to facilitate the mounting and assembling of the washing tub 31, and the tub bottom positioning hole 105, the tub bottom mounting hole 106, the cover plate mounting hole 107 and the mold process positioning hole are covered after the mounting of the washing tub 31 is completed.
Additionally, there are no holes in the visible area when viewed from inside after the balance ring 4, the cover plate and the tub bottom 32 are mounted to the washing tub 31 of the present disclosure. Specifically, at least a majority of the washing tub 31 does not define any holes, and even the washing tub 31 is provided with a hole structure, the hole structure will be covered after the balance ring 4, the water-returning cover plate 5 and the tub bottom 32 or the like have been mounted. It can be seen that the washing tub 31 of the washing tub assembly 3 of the present disclosure has no holes or only a few holes (which are further covered), thus, in the washing machine having the washing tub assembly 3, the water injected into the washing tub assembly 3 will be retained in the washing tub assembly 3 in the washing process, so as to reduce the amount of the water discharged from the washing tub assembly 3 in the washing process, such that the vast majority of the water injected into the washing tub assembly 3 is used to rinse the clothes, and the water consumption in the process of washing the clothes can be properly reduced, which is water-saving and environment-friendly.
In the washing machine 100 according to some embodiments of the present disclosure, in the washing process, the number of the water leakage holes 104 on the washing tub 31 is appropriate and the water leakage hole 104 is located at a bottom of the washing tub 31, the water in the washing tub 31 is not prone to enter the water accommodation tub 2, and even the water in the washing tub 31 enters between the washing tub 31 and the water accommodation tub 2 via the water leakage hole 104, the water level in the washing tub 31 is considerably higher than the water level between the washing tub 31 and the water accommodation tub 2, thereby achieving the dynamic water saving effect; in the dehydration process, the water in the washing tub 31 is discharged out of the washing tub 31 mainly via the water outlet passage 101, and a small amount of the water is discharged out of the washing tub 31 through the water leakage hole 104, thereby improving the dehydrating effect.
Through the design of the washing tub 31 of the present disclosure, a majority of washing water is retained in the washing tub 31, and only a small amount of water will enter between the washing tub 31 and the water accommodation tub 2, such that the water can be greatly saved, and a water saving rate reaches 40% to 50%.
The washing machine provided with this type of washing tub 31 has the same technical effect described above, and the water in the washing tub 31 is discharged out of the washing machine mainly through the water outlet passage 101 at the top of the washing tub 31.
A method for washing clothes using the washing machine with the new washing tub 31 includes discharging water in the washing tub 31 out of the washing tub 31 mainly through the water outlet passage 101 at the top of the washing tub 31 by means of the high-speed rotation of the washing tub 31, thereby achieving the purpose of dehydration, which can shorten the working time of the washing machine and improve the washing efficiency.
Additionally, the circumferential wall of the bottom of the washing tub 31 defines the water leakage hole 104, such that the dehydrating effect of the washing machine 100 can be improved, that is, the problem of partial inadequate dehydration can be improved.
In the conventional washing machine, a lot of dehydration holes are provided at a pattern zone of the inner tub, the number of the dehydration holes ranges from 160 to 3000, and therefore, when the washing inner tub with dehydration holes at the pattern zone of the conventional washing machine performs washing, the water level in the inner tub and the water level in the outer tub are consistent. However, in the washing process, only the water in the washing tub is used for washing, and since the water level in the inner tub and the water level in the outer tub are consistent, a large amount of washing water is present between the inner tub and the outer tub, which will result in a relatively large waste. However, in the present disclosure, there are no dehydration holes at the pattern area of the washing tub, and even in some embodiments of the present disclosure where the water leakage hole 104 is provided, the number of the water leakage holes 104 ranges from 24 to 40, and preferably the number of the water leakage holes 104 is 28, much smaller than the number of the dehydration holes at the center of the conventional washing tub, such that the water level of the inner tub is higher than the water level of the outer tub during the washing, thereby achieving a good dynamic water saving effect.
Other constitutions and operations of the washing machine according to some embodiments of the present disclosure are well known by those skilled in the art, which will not be described in detail herein.
