The present embodiment provides a tub 1 for a laundry treating apparatus.

Referring to fig. 1 to 3, the tub 1 includes a tub 11, a tub bottom 12, and a baffle 13. The tub bottom 12 closes the bottom end of the tub 11, and referring to fig. 3, 4, 5 and 6, the tub bottom 12 is provided with a drain port 121 through which water in the tub 1 is drained.

Referring to fig. 1 to 3, in a top projection of the tub 1, the guide plate 13 covers the drain port 121. It can be understood that the guide plate 13 does not close the drain opening 121 to ensure that the water in the tub 1 can be drained through the drain opening 121.

Referring to fig. 8, an embodiment of the present application further provides a drum assembly including a washing drum 2, a drum cover 4, a pulsator 3, and a water tub 1 according to any embodiment of the present application. A washing tub 2 rotatably disposed in the water tub 1, and a pulsator 3 rotatably disposed at the bottom of the washing tub 2; the tub cover 4 surrounds the top end of the tub 1, and specifically, the tub cover 4 covers a gap between the top end of the tub 1 and the top end of the washing tub 2.

It will be appreciated that the wash drum 2 is a perforated inner drum, the wash drum 2 being dependent upon a water tub for holding water.

In the process of washing clothes, the impeller 3 and the washing drum 2 rotate, for example, rotate in the same direction at a speed of 150-250 rpm, the impeller 3 and the washing drum 2 can stir a large amount of water in the water containing drum 1, the water in the water containing drum 1 is upwards rolled up along the drum wall of the water containing drum 1, the water flow spirally rises along the drum wall of the water containing drum 1 under the action of centrifugal force, after the water flow rises to a certain height, the water flow is blocked by the drum cover 4 and turns to flow to the bottom surface of the drum cover 4, the water flow flows from the radial outer side of the drum cover 4 to the radial inner side of the drum cover 4, finally the water flows out from the inner edge of the drum cover 4, the water flow after the water flow enters the washing drum 2 from the upper part of the washing drum 2, the clothes in the washing drum 2 are washed, the dissolution of a detergent can be accelerated, and the cleaning effect of the clothes treatment equipment is improved.

It can be understood that the water in the tub 1 is constantly replenished at the bottom side while the washing tub 2 and the pulsator 3 wind up the water current. In the related art, the supplementary water flow at the water outlet 121 at the bottom of the barrel is greatly disturbed, so that a large vortex is generated, the water flow at the water outlet 121 cannot be supplemented in time in a large amount, the water flow at the side of the water outlet 121 cannot rise to the barrel cover, and no water flow or a small amount of water flow is sprayed in a part of the barrel cover.

The water containing barrel of the embodiment of the application, at the washing clothing in-process, when rivers flow to the top region of outlet 121 along circumference, because the water conservancy diversion effect of guide plate 13, partial rivers flow from the surface of guide plate 13, rivers can flow through guide plate 13 comparatively smoothly, consequently, can in time supply upwards to curl up required water yield for the rivers homoenergetic of 1 circumference of water containing barrel each position department can rise to bung 4 departments, improves the homogeneity that bung 4 goes out the water along circumference.

Note that, since the middle region of the tub 1 is provided with the pulsator 3 avoiding region, the drain port 121 is generally disposed outside the pulsator 3 avoiding region.

The drainage port 121 is not limited to be disposed, and in some embodiments, the tub bottom 12 is provided with a recessed area 120, the drainage port 121 is disposed at the bottom of the recessed area 120, and water is collected into the recessed area 120 and then drained from the drainage port 121, so that water can be drained from the drainage port 121 more smoothly during drainage. Since the recessed area 120 may interfere with the flow of the replenishing water in the circumferential direction and affect the upward rolling performance of the water, in some embodiments, the deflector 13 is disposed at the recessed area 120. That is, the flow characteristics of the water flow at the depressed region 120 are improved by the deflector 13. Specifically, when the water flows to the recessed area 120 along the circumferential direction, due to the diversion effect of the diversion plate 13, part of the water flows through the surface of the diversion plate 13, and the water flows can smoothly flow through the diversion plate 13, so that the water amount required by upward rolling can be timely supplemented, the water flows at all positions of the circumferential direction of the water containing barrel 1 can be lifted to the barrel cover 4, and the uniformity of water outflow of the barrel cover 4 along the circumferential direction is improved.

In some embodiments, the length of the guide plate 13 is 1/2 to 4/5 of the length of the recessed area 120 along the circumferential direction of the tub 1, that is, the guide plate 13 covers 1/2 to 4/5 of the length of the recessed area 120 in a top view projection of the tub 1. For example, 1/2, 2/3, 3/4, 4/5, etc., so as not to affect the drainage performance of the tub 1 as much as possible while satisfying the diversion.

It should be noted that the length of the baffle 13 refers to the largest dimension of the baffle 13 in the circumferential direction of the tub bottom 12. The length of the depressed region 120 refers to the largest dimension of the depressed region 120 in the circumferential direction of the tub bottom 12.

In some embodiments, the baffle 13 can be completely embedded within the recessed area 120, i.e., no portion of the baffle 13 extends beyond the recessed area 120; in other embodiments, the baffle 13 may also be disposed above the recessed area 120, that is, the baffle 13 has a height higher than the recessed area 120; in still other embodiments, the baffle 13 may also be partially located within the recessed area 120 and partially located above the recessed area 120, without limitation.

For example, referring to fig. 3, the top surface of the flow guiding plate 13 does not exceed the top side of the corresponding side wall of the depressed area 120, that is, the flow guiding plate 13 is completely embedded in the depressed area 120, so that the flow guiding plate 13 does not protrude from the surface of the non-depressed area of the tub bottom 12, does not generate resistance to the water flow flowing along the circumferential direction, and does not substantially affect the flow path of the water flow, so that the water flow can smoothly flow through the flow guiding plate 13, and the uniformity of the water flow on the inner surface of the tub body 11 is improved.

Note that, in order to ensure that the tub 1 can drain through the drain opening 121, a portion of the edge of the baffle 13 is spaced apart from the corresponding sidewall of the recessed area 120 to form a flow passage 1a therebetween, and water in the tub 1 flows through the flow passage 1a toward the lower portion of the recessed area 120 and reaches the drain opening 121.

In some embodiments, the flow area of the flow channel 1a is not smaller than the flow area of the drain opening 121. When the tub 1 is drained, the overflow passage 1a does not form a throttling effect, and does not extend the draining time of the tub 1 under the same condition, that is, the guide plate 13 does not affect the draining performance of the tub 1.

In some embodiments, referring to fig. 2 and 5 in combination, the baffle 13 contacts the outer sidewall 120a of the recess 120 along the radially outward outer edge 13a of the tub 1. That is, there is no space between the outer edge 13a of the baffle 13 and the outer sidewall 120a corresponding to the depressed area 120, so that the water can smoothly flow through the boundary between the outer edge 13a of the baffle 13 and the outer sidewall 120a corresponding to the depressed area 120 when the water gradually flows toward the edge of the tub bottom 12 by the centrifugal force.

In some embodiments, referring to fig. 2 and 5, the front edge 13b of the baffle 13 on the front side along the rotation direction of the washing drum 2 contacts with the corresponding front sidewall 120b of the depressed area 120. When the washing drum 2 rotates, the water flow is driven to rotate in the same direction, and the water flow can smoothly transit to the top surface of the guide plate 13 from the non-concave area of the tub bottom 12.

In some embodiments, referring to fig. 2 and 5 in combination, the baffle 13 is disposed along the radially inward inner edge 13c of the tub 1 and the inner side wall 120c corresponding to the recessed region 120 at an interval to form at least a portion of the flow passage 1a therebetween. The flow velocity of the water flow at the inner edge 13c of the baffle 13 is relatively small, and therefore, the spacing of the inner edge 13c from the inner side wall 120c has less influence on the flow of the water flow and can also facilitate drainage.

In some embodiments, referring to fig. 2 and 5, the rear edge 13d of the baffle 13 on the rear side along the rotation direction of the washing drum 2 is spaced from the corresponding rear sidewall 120d of the depressed area 120. Specifically, the interval between the rear edge 13d of the deflector 13 and the rear sidewall 120d corresponding to the recessed area 120 is much smaller than the length of the recessed area 120, and when the water flow flows to the rear edge 13d of the deflector 13, the water flow can wash through the interval under the action of the motion inertia without entering the lower space of the recessed area 120 from the interval, the influence of the interval on the flow of the water flow is small, and the drainage of the tub 1 can be facilitated. In addition, most of the water flow is lifted up by the deflector 13 when moving to the deflector 13, and the water flow is less when moving to the rear edge 13d of the deflector, so that the arrangement of the interval does not have a great influence on the water flow.

In some embodiments, referring to fig. 2, the distance d1 between the rear edge 13d of the baffle 13 at the rear side in the rotation direction of the washing drum 2 and the corresponding rear sidewall 120d of the recessed area 120 is not more than 35 mm. The washing drum 2 is, for example, rotated at a speed of 160 to 250 revolutions per minute during the rotation, which is in such a range that the water flow can flush through the gap by means of the inertia of the movement.

Illustratively, the distance d1 between the rear edge 13d of the rear side of the baffle 13 in the rotation direction of the washing drum 2 and the corresponding rear side wall 120d of the recessed area 120 is 15mm to 35mm, for example, 15mm, 18mm, 20mm, 25mm, 28mm, 30mm, 35mm, etc. This distance range enables both a sufficient flow channel 1a area and a water flow to flush through the gap.

The installation manner of the baffle 13 is not limited as long as the baffle 13 can be fixed on the tub bottom 12. For example, in some embodiments, referring to fig. 3 to 6, the barrel bottom 12 includes a plurality of supporting pillars 123 protruding from the bottom surface of the recessed area 120, the baffle 13 is provided with a connecting hole 13f and supported on the top ends of the supporting pillars 123, and a screw passes through the connecting hole 13f and is screwed into the supporting pillars 123. In the assembling process, the guide plate 13 is only required to be placed on the support column 123, and the support column 123 plays a role in positioning and supporting the guide plate 13; and then the screw is screwed from top to bottom, so that the assembly mode is simple and convenient.

The number of the support columns 123 is not limited as long as the baffle 13 can be reliably supported. For example, the number of the support columns 123 is two, three, or more than three. For example, in the embodiment of the present application, the number of the support columns 123 is three, and three support columns 123 form three-point stable support for the baffle 13, without occupying too much installation space.

In some embodiments, referring to fig. 2 and 5, the tub bottom 12 includes a first annular portion 12a and a second annular portion 12b connected to each other in a radial direction of the tub 1, the first annular portion 12a surrounds a radially outer side of the second annular portion 12b, a bottom end of the tub 11 is engaged with the first annular portion 12a, and a height of the first annular portion 12a is higher than a height of the second annular portion 12b, that is, a stepped structure is formed at an intersection of the first annular portion 12a and the second annular portion 12 b. A portion of the recessed region 120 is located on the first annular portion 12a and another portion is located on the second annular portion 12 b.

Referring to fig. 7, the baffle 13 includes a first sub-plate 131 and a second sub-plate 132 connected and bent to each other, the first sub-plate 131 is higher than the second sub-plate 132, the first sub-plate 131 is located in the recess 120 corresponding to the first annular portion 12a, and the second sub-plate 132 is located in the recess 120 corresponding to the second annular portion 12 b. That is, in the radial direction, the shape of the baffle 13 is adapted to the shape of the first annular portion 12a and the second annular portion 12 b.

In some embodiments, the surface of the second annular portion 12b is spirally raised in the rotation direction of the washing tub 2 along the circumferential direction of the tub 1, thus facilitating the water flow to be rolled up.

The first sub-board 131 and the second sub-board 132 may be a split structure and fixedly connected together by welding, bonding, or the like. The first sub-board 131 and the second sub-board 132 may also be an integrally molded structure, for example, an integrally injection molded plastic part; or an integrally formed sheet metal part.

In some embodiments, the tub 11 and the tub bottom 12 may be integrally formed structures, for example, integrally injection molded; or a split structure, and fixedly connected together by ultrasonic welding or the like, without limitation.

The embodiment of the application also provides a clothes treatment device, which comprises a box body, a power mechanism and the barrel assembly in any embodiment of the application, wherein the barrel assembly is arranged in the box body, and the impeller 3 and the washing barrel 2 are in driving connection with the power mechanism.

The clothes treating apparatus includes a water current washing mode, and a power mechanism drives the pulsator 3 and the washing tub 2 to rotate in the same direction. For example, the pulsator 3 and the washing tub 2 are both rotated in a clockwise direction in fig. 2.

According to the clothes treatment equipment provided by the embodiment of the application, in the water flow washing mode, water flow after water is discharged from the barrel cover 4 enters the washing barrel 23 from the upper part of the washing barrel 23, so that a washing effect is generated on clothes in the washing barrel 23, the dissolution of a detergent can be accelerated, and the cleaning effect of the clothes treatment equipment is improved; because the impeller 3 and the washing drum 2 rotate in the same direction, the abrasion to clothes can be reduced, and a certain anti-winding effect can be achieved.

It can be understood that in the water current washing mode, the rotation speeds of the washing tub 2 and the pulsator 3 may be the same, that is, the pulsator 3 and the washing tub 2 rotate in the same direction in synchronization, and there is no relative movement between the pulsator 3 and the washing tub 2; in some alternative embodiments, there may also be a small difference in rotational speed between the pulsator 3 and the washing tub 2.
