In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
As shown in fig. 1 and 2, the utility model provides an outer cylinder, which comprises a body 1, a dividing angle 2, a circulating cavity 3 arranged at the bottom of the body 1 and a water outlet arranged at the bottom of the circulating cavity 3, wherein the dividing angle 2 is arranged at the joint of the circulating cavity 3 and any side of the body 1, and a water return section 301 of the circulating cavity 3 is connected with the body 1 through the dividing angle 2;
from the division angle 2 downwards, the horizontal distance between the backwater section 301 and the center of the body 1 gradually increases.
The dividing angle 2 is preferably a round angle, and when the water flow in the washing stage collides with the dividing angle 2, one part moves along the inner wall of the body 1, and the other part moves along the trend of the water return section 301.
The partition angle 2 and the return water section 301 may be provided on either side of the body 1. Specifically, the position of the partition angle 2 and the return water section 301 is related to the rotational direction of the inner cylinder 8. For example, when the inner tub 8 rotates clockwise in the dehydration stage of the washing machine, the partition angle 2 and the return water section 301 are provided on the left side of the main body 1.
During the dehydration stage, after water flow is thrown out from the inner cylinder 8 due to centrifugal action, the water flow moves along the inner walls of the body 1 and the circulating cavity 3, and part of water flow is discharged from a water outlet at the bottom of the circulating cavity 3; the residual water flow moves in the reverse direction at the backwater section 301, and the water flow moving in the anticlockwise direction and the water flow thrown out from the inner cylinder 8 and moving in the clockwise direction are flushed down and discharged from the water outlet at the bottom of the circulation cavity 3.
In the washing stage, since the water level at the bottom of the tub 7 is high, for example, the water level in the washing stage is at least lower than that of the laundry, the circulation of water is different from that in the dehydrating stage. At this time, due to the existence of the dividing angle 2, the water flow moving in the clockwise direction is divided into two parts at the dividing angle 2, and one part continues to circulate in the clockwise direction in the gap between the inner cylinder 8 and the outer cylinder 7; the other part moves along the inner wall of the backwater section 301 of the circulation cavity 3, namely falls down from the partition angle 2, when the backwater section returns to the bottom of the circulation cavity 3, water flows and water flows moving clockwise are flushed, jump up, and circulate at the circulation cavity 3 again along the clockwise direction due to the driving of the rest water flows moving clockwise, so that the bottom of the outer cylinder 7 is circularly flushed, dirt accumulated at the bottom of the outer cylinder 7 is avoided, and the user experience is influenced.
In yet another embodiment of the present utility model, the inner tub 8 is rotated counterclockwise during the dehydration stage of the washing machine, and the partition angle 2 and the return water section 301 are disposed at the right side of the body 1.
During the dehydration stage, after water flow is thrown out from the inner cylinder 8 due to centrifugal action, the water flow moves along the inner walls of the body 1 and the circulating cavity 3, and part of water flow is discharged from a water outlet at the bottom of the circulating cavity 3; the residual water flow moves in the reverse direction at the water return section 301, and the water flow moving clockwise and the water flow thrown out from the inner cylinder 8 and moving anticlockwise are flushed down and discharged from the water outlet at the bottom of the circulation cavity 3.
When in the washing stage, the water circulation condition of the water flow is different from that of the dewatering stage due to the higher water level at the bottom of the outer cylinder. At this time, due to the existence of the dividing angle 2, the water flow moving in the counterclockwise direction is divided into two parts at the dividing angle 2, and one part continues to circulate in the counterclockwise direction in the gap between the inner cylinder 8 and the outer cylinder 7; the other part moves along the inner wall of the backwater section 301 of the circulation cavity 3, namely falls down from the partition angle 3, and water flows are flushed with water flowing along the anticlockwise direction when at the bottom of the circulation cavity 3, jump up and circulate at the circulation cavity 3 again along the anticlockwise direction, so that the bottom of the outer cylinder is circularly flushed, and dirt accumulated at the bottom of the outer cylinder is prevented from affecting user experience.
The water return section 301 may be provided in a straight line, an arc or other form. However, there is a corner when the linear return water section 301 is connected to the second connection section 303 of the circulation chamber 3, and there is a large loss in the speed of the water flow due to the corner when the water flow moves along the second connection section 303 and the return water section 301.
Preferably, the backwater section 301 of the present utility model has an arc structure, and its central angle is less than or equal to 90 °.
Further, the central angle of the water return section 301 may be set to about 60 °, so that the direction of the water return section 3 at the joint of the water return section 301 and the dividing angle 2 is substantially consistent with the tangential direction of the other side body 1, so that the water flow moving along the inner wall of the water return section 301 is as close to 0 as possible when the water flow is in collision with the water flow moving along the tangential direction of the inner barrel 8, the water flow falls to the bottom of the circulation cavity 3, and is discharged from the water outlet arranged at the bottom of the circulation cavity 3, and the water flow is prevented from being scattered by collision when the directions are inconsistent, and the water flow of the rest is prevented from being influenced.
The circulating cavity 3 comprises a backwater section 301 and a second connecting section 303, and further comprises a first connecting section 302, wherein the first connecting section 302 is connected with the body 1, and the second connecting section 303 is arranged between the first connecting section 302 and the backwater section 301.
The first and second connection sections 302, 303 may be rectilinear, arcuate, or otherwise. Considering that when the first connecting section 302 and the second connecting section 303 are arranged in a straight line shape, a corner exists at the joint of the first connecting section 302 and the second connecting section 303, and the speed of water flow can be greatly lost when moving in the circulation cavity 3, the first connecting section 302 and the second connecting section 303 of the utility model adopt arc structures.
Further, the radii of the second connection section 303 and the return water section 301 are equal, and the central angle of the second connection section 303 is set to 90 °.
From the connection between the first connecting section 302 and the body 1 to the connection between the first connecting section 302 and the second connecting section 303, the distance between the first connecting section 302 and the center of the body 1 gradually increases, i.e. the distance between the inner cylinder 8 and the outer cylinder 7 gradually increases.
Preferably, the first connecting section 302 extends along the tangential direction of the connection part between the body 1 and the first connecting section 302, that is, the body 1 and the first connecting section 302 are in smooth transition, so that the phenomenon that the flow of water flow is influenced by the existence of a corner can be avoided, and no sharp angle exists outside the outer cylinder 7, thereby being convenient to carry and install.
The first connection section 302 and the second connection section 303 may also be arranged as a smooth transition, i.e. at the junction of the first connection section 302 and the second connection section 303, the tangential direction of both the first connection section 302 and the second connection section 303 is the same.
The second connection section 303 and the water return section 301 may also be provided with a smooth transition, i.e. at the connection between the second connection section 303 and the water return section 301, the tangential directions of the second connection section 303 and the water return section 301 are the same.
Further, the depth of the circulation chamber 3 is greater than or equal to 1/2 of the depth of the body 1 and less than or equal to the depth of the body 1, and preferably, the circulation chamber 3 of the present utility model is set to 3/4 of the depth of the body 1.
In one or more embodiments of the present utility model, one side of the body 1 is connected with the backwater section 301 of the circulation cavity 3 through the dividing angle 2, and the other joints, including the joint between the first connecting section 302 and the body 1, the joint between the first connecting section 302 and the second connecting section 303, and the joint between the second connecting section 303 and the backwater section 301 are all smooth, so that on one hand, the appearance of the outer cylinder 7 is attractive, and on the other hand, the speed of the water flow in the inner part is not greatly lost when the movement direction is changed, and the local circulation of the water flow at the circulation cavity 3 is not affected, thereby ensuring the flushing and dewatering efficiency of the water flow to the bottom of the outer cylinder 7.
The utility model also provides a drum washing machine, which comprises an inner drum 8 and an outer drum 7 nested outside the inner drum 8, wherein the outer drum 7 is adopted by the outer drum.
Preferably, the inner cylinder 8 and the outer cylinder 7 are coaxially nested, so that gaps between the body 1 of the outer cylinder 7 and the inner cylinder 8 are uniformly distributed, the distance between the first connecting section 302 of the circulation cavity 3 and the inner cylinder 8 is gradually increased, and then the outer cylinder 7 is closed through the second connecting section 303 and the water return section 301.
Fig. 3 is a schematic view of water circulation between the outer tub 7 and the inner tub 8 in the washing stage, and the arrow direction in fig. 3 is the inner tub rotation direction and the water flow direction. As shown in fig. 3, when the inner tub 8 rotates clockwise in the washing stage, the water flow at the bottom is divided into two circulating water flows at the dividing angle 2, which are respectively an upper circulating water flow and a lower circulating water flow.
In the upper circulating water flow, the water flow sequentially passes through the left gap 4, the upper gap 5 and the right gap 6 from the dividing angle 2 due to the centrifugal force, and then returns to the dividing angle 2 again for the next circulation.
In the lower circulating water flow, due to the blocking of the dividing angle 2, the water flow moves along the inner wall of the water return section 301 and the inner wall of the second connecting section 303, but at the bottom of the outer cylinder 7, the part of the counterclockwise water flow collides with the water flow moving clockwise due to the rotation of the inner cylinder 8, and then the water flow is brought to the dividing angle 2 again by the rest of the clockwise water flow, so that the next upper circulation or lower circulation is performed.
In this process, the bottom of the outer tub 7 is continuously washed by the lower circulating water flow, so that dirt cannot adhere to the bottom of the outer tub 7, thereby achieving the effect of cleaning the bottom of the outer tub 7.
When the rotation direction of the inner cylinder 8 is changed in the washing stage, the circulation direction of the water flow between the inner cylinder 8 and the outer cylinder 7 is changed to anticlockwise rotation due to the action of centrifugal force, the water flow sequentially passes through the right gap 6, the upper gap 5 and the left gap 4, and then passes through the right gap 6 again to perform the next circulation, and at this time, the action of the dividing angle 2 can be ignored.
Fig. 4 is a schematic view of water circulation between the outer tub 7 and the inner tub 8 in the dehydration stage, and the arrow direction in fig. 4 is the rotation direction and the water flow direction of the inner tub 8. As shown in fig. 4, the inner cylinder 8 rotates clockwise during the dehydration stage, because the outer cylinder 7 empties the washing water during the dehydration stage, when the inner cylinder 8 rotates at a high speed, the water flow at the right gap 6 moves along the inner wall of the first connecting section 302 of the circulation cavity 3 due to the centrifugal force, and at this time, a part of the water thrown out by the inner cylinder 8 is discharged from the water outlet at the bottom of the circulation cavity 3 after passing through the right gap 6 and the first connecting section 302; part of water flows move along the inner walls of the second connecting section 303 and the water return section 301 after passing through the right gap 6 and the first connecting section 302 due to the inertia effect, then falls to the bottom of the circulating cavity 3, and is discharged from a water outlet arranged at the bottom of the circulating cavity 3; there is also a part of the water flow which, when moving along the inside of the second connection section 303, the return water section 301, is flushed down with the water flow which moves in the clockwise direction due to the centrifugal effect and is discharged from the water outlet at the bottom of the circulation chamber 3.
In a further embodiment of the utility model, when the inner drum 8 rotates anticlockwise during the dehydration stage, the dividing angle 2 and the return water section 301 are arranged on the right side of the body 1, i.e. the circulation chamber 3 in this embodiment is opposite to the circulation chamber 3 in the above embodiment.
When the inner drum 8 rotates counterclockwise in the washing stage, the water flow at the bottom is divided into two circulating water flows at the dividing angle 2, which are respectively an upper circulating water flow and a lower circulating water flow.
In the upper circulating water flow, due to the centrifugal force, the water flow sequentially passes through the right gap 6, the upper gap 5 and the left gap 4 from the dividing angle 2, and then returns to the dividing angle 2 again for the next circulation.
In the lower circulating water flow, due to the blocking of the dividing angle 2, the water flow moves along the inner wall of the water return section 301 and the inner wall of the second connecting section 303, but at the bottom of the outer cylinder 7, the part of the clockwise water flow collides with the water flow moving in the counterclockwise direction due to the rotation of the inner cylinder 8, and then the water flow is brought to the dividing angle 2 again by the rest of the counterclockwise water flow, so that the next upper circulation or lower circulation is performed.
In this process, the bottom of the outer tub 7 is continuously washed by the lower circulating water flow, so that dirt cannot adhere to the bottom of the outer tub 7, thereby achieving the effect of cleaning the bottom of the outer tub 7.
When the rotation direction of the inner cylinder 8 is changed in the washing stage, the circulation direction of the water flow between the inner cylinder 8 and the outer cylinder 7 is changed to clockwise rotation due to the action of centrifugal force, the water flow sequentially passes through the left gap 4, the upper gap 5 and the right gap 6, and then passes through the left gap 4 again to perform the next circulation, and at this time, the action of the dividing angle 2 can be ignored.
The inner cylinder 8 rotates anticlockwise during the dehydration stage, because the outer cylinder 7 empties washing water during the dehydration stage, when the inner cylinder 8 rotates at a high speed, water flow at the left gap 4 moves along the inner wall of the first connecting section 302 of the circulation cavity 3 due to the centrifugal force, and at the moment, part of water thrown out by the inner cylinder 8 is discharged from a water outlet at the bottom of the circulation cavity 3 after passing through the left gap 4 and the first connecting section 302; part of water flows move along the inner walls of the second connecting section 303 and the water return section 301 after passing through the left gap 4 and the first connecting section 302 due to the inertia effect, then falls to the bottom of the circulating cavity 3, and is discharged from a water outlet arranged at the bottom of the circulating cavity 3; there is also a part of the water flow which, when moving along the inside of the second connection section 303, the return water section 301, is flushed down with the water flow moving in the counter-clockwise direction due to the centrifugal effect and is discharged from the water outlet at the bottom of the circulation chamber 3.
In the dehydration stage of the drum washing machine, the rotational speed of the inner drum 8 is higher, the centrifugal effect of water flow is larger, washing water between the outer drum 7 and the inner drum 8 is emptied, and the water flow can be closely clung to the body 1 of the outer drum 7 and the inner wall of the first connecting section 302, so that the water flow is discharged from the water outlet at the bottom of the circulation cavity 3 or is partially circulated once or more times in the circulation cavity 3 and then is discharged from the water outlet, the dehydration efficiency is improved, and the time consumed by repeated circulation of the water flow between the inner drum 8 and the body 1 for a plurality of times due to the action of the centrifugal force is reduced.
The foregoing description is only a preferred embodiment of the present utility model, and the present utility model is not limited to the above-mentioned embodiment, but is not limited to the above-mentioned embodiment, and any simple modification, equivalent change and modification made by the technical matter of the present utility model can be further combined or replaced by equivalent embodiments within the scope of the technical proposal of the present utility model without departing from the scope of the technical proposal of the present utility model.
