The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring first to fig. 1, fig. 1 is a schematic structural view of a first embodiment of a tub assembly of a pulsator washing machine according to the present invention. As shown in fig. 1, the pulsator washing machine of the present invention includes a casing 1 and a tub assembly disposed in the casing 1. The casing 1 is a box structure, and the top of the casing 1 is provided with a throwing opening and a door capable of closing or opening the throwing opening. The tub assembly includes an outer tub 3, an inner tub 4, and a pulsator 5, wherein the outer tub 3 is vertically installed in the cabinet through a vibration damping member 2, and a tub opening of the outer tub 3 and a throwing opening of the casing 1 are aligned with each other. The inner tub 4 is rotatably provided in the outer tub 3, and laundry can be contained in the inner tub 4. The pulsator 5 is rotatably provided at the bottom of the inner tub 4. The power system (not shown in the figure) of the pulsator washing machine comprises a driving device, a first transmission assembly, a second transmission assembly and a clutch assembly. One of the first transmission assembly and the second transmission assembly is connected with the inner barrel 4, and the other one is connected with the impeller 5. The clutch assembly is disposed between the first and second transmission assemblies and the driving device so as to selectively connect the first or second transmission assembly with the driving device indirectly, thereby transmitting the driving force of the driving device to the inner tub 4 or the pulsator 5 through the first or second transmission assembly. Since the power system has the same structure as that of the conventional inner tub and pulsator dual-rotation pulsator type washing machine, detailed description thereof will not be provided.

With continued reference to fig. 1, the barrel assembly further includes a first water-repelling member 6, and the first water-repelling member 6 is disposed on the inner sidewall of the inner barrel 4. Specifically, the first water repelling member 6 is vertically or obliquely arranged, and the thickness of the first water repelling member 6 gradually increases from bottom to top.

In the above embodiment, the arrangement of the first water-repellent member 6 in the vertical direction or the oblique direction specifically means: after the side wall (i.e., the tub ring portion) of the inner tub 4 is cut along a vertical line and unfolded into a rectangle, the first water repelling member 6 is disposed along the height direction (i.e., the vertical line direction) of the rectangle, and this is the first water repelling member 6 disposed vertically on the inner side wall of the inner tub 4. At this time, the first water repelling member 6 is in the same direction as the axis of the inner tub 4. The arrangement mode does not increase the installation difficulty between the first water stirring component 6 and the inner barrel 4, the first water stirring component 6 is not required to adapt to the curvature of the side wall of the inner barrel 4 when being connected with the inner barrel 4, and the first water stirring component 6 is not required to be provided with curvature and is more convenient to produce and process; the first water repelling member 6 is disposed in a height direction which is not parallel to the above-mentioned rectangle (although such a non-preferable case that is perpendicular to the height direction is not included), that is, the first water repelling member 6 is disposed in an inner sidewall of the inner tub 4 in an oblique direction. As an example, the first water repelling member 6 may be inclined at an angle of any angle between 15 ° and 35 ° with respect to the height direction of the rectangle. The arrangement facilitates spiral rising of the washing water along the barrel wall when the first water stirring component 6 stirs the washing water in the inner barrel 4, and improves the capacity of the first water stirring component 6 for lifting the washing water and increasing the overturning degree of the washing water.

In addition, the thickness of the first water repelling member 6 specifically means: the distance between one side of the first water stirring member 6 close to the inner sidewall of the inner tub 4 and one side thereof close to the center of the inner tub 4. In the case of the first water repelling member 6 arranged vertically, as shown in the orientation of fig. 1, the thickness of the first water repelling member 6 is its dimension h1 in the horizontal direction.

In the case of providing the first water repelling member 6, when the inner tub 4 rotates to wash the laundry, the upper portion of the first water repelling member 6 has a large thickness and a large contact area with the washing water, so that the upper portion thereof has a more significant agitating effect on the washing water, and the washing water on the upper portion of the inner tub 4 rotates at a higher speed and has a lower pressure. The lower part of the first water-stirring member 6 has a small thickness and a small contact area with the washing water, so that the lower part of the first water-stirring member has a weak stirring effect on the washing water, and the washing water at the lower part of the inner tub 4 has a slow rotating speed and a large pressure. Under the action of pressure difference, the washing water at the bottom of the inner barrel 4 flows upwards, so that the clothes at the bottom of the inner barrel 4 are promoted to roll upwards, the condition that the clothes are deposited at the bottom of the inner barrel is improved, and the overall washing effect of the clothes in the inner barrel 4 is improved.

Further, the overall shape of the first water repellent member 6 is a long straight strip. As shown in fig. 1, the first water-repellent member 6 having a long shape extends from the bottom of the inner tub 4 to the lower portion of the tub opening, ensuring a washing water agitation range of the first water-repellent member 6.

As an example, the number of the first water repelling members 6 is plural (two or more), and the plural first water repelling members 6 are uniformly distributed along the circumferential direction of the inner tub 4 to uniformly and efficiently agitate the washing water in the inner tub 4.

In a specific embodiment, the first water stirring member 6 is provided with a water passing hole (not shown) having both ends communicated with the inner space of the inner tub 4, so that the first water stirring member 6 can allow a part of the washing water to pass through the water passing hole when stirring the washing water, thereby reducing resistance of the washing water to the first water stirring member 6 and reducing load of the driving device.

In the first embodiment of the present invention, as shown in fig. 1, the first water-stirring member 6 is directly connected to the wall of the inner barrel 4, and the two are connected together by means of screw joint, clamping, welding, etc.

Referring to fig. 2, fig. 2 is a schematic structural view of a tub assembly of a pulsator washing machine according to a second embodiment of the present invention. As shown in fig. 2, in the second embodiment of the present invention, an installation groove 8 is formed on the inner sidewall of the inner barrel 4, and in an assembled state, the first water-stirring member 6 is accommodated in the installation groove 8, that is, one side of the first water-stirring member 6 close to the barrel wall of the inner barrel 4 is installed in the installation groove 8. The mounting groove 8 is provided to hide at least a portion of a mounting gap between the first water repelling member 6 and the inner sidewall of the inner tub 4. Specifically, the mounting groove 8 is a groove having a certain depth. When the first water stirring member 6 is arranged in the mounting groove 8, the first water stirring member 6 is abutted against the bottom of the mounting groove 8, and the wall of the mounting groove 8 can block a mounting gap between the first water stirring member 6 and the bottom of the groove, so that clothes are prevented from being directly contacted with the mounting gap and being clamped and plugged in the mounting gap. In practical implementation, the mounting groove 8 may only accommodate the water facing side of the first water stirring member 6, only hide the mounting gap of the water facing side of the first water stirring member 6, or entirely accommodate one end of the first water stirring member 6 close to the tub wall. For example, when the first water repelling member 6 has an end near the wall of the tub shaped like a rectangular structure, the mounting groove 8 is a rectangular groove recessed to the outside of the inner tub 4, so that the end of the first water repelling member 6 near the wall of the tub is received in the rectangular groove, thereby hiding the mounting gap between the first water repelling member 6 and the inner tub 4.

As shown in fig. 1 or 2, in a third embodiment of the present invention, the tub assembly further includes a second water stirring member 7 provided on the pulsator 5. The second water repellent member 7 is disposed in a radial direction of the pulsator 5, and a thickness of the second water repellent member 7 is gradually reduced from an edge to a center of the pulsator 5.

In the above embodiment, the thickness of the second water repelling member 7 specifically means: the distance between one side of the second water stirring component 7 close to the upper surface of the impeller 5 and one side of the second water stirring component close to the barrel opening of the inner barrel 4. As shown in the orientation of fig. 1, in the case where the upper surface of the pulsator 5 is a horizontal surface, the thickness of the second water-repellent member 7 is a dimension h2 in the vertical direction.

Under the condition of simultaneously arranging the first water stirring component 6 and the second water stirring component 7, when the inner barrel 4 rotates and washes clothes, the thickness of one side of the second water stirring component 7 close to the edge of the impeller 5 is larger, and the contact area with washing water is larger, so that the stirring effect of the part on the washing water is more remarkable, and the washing water at the edge of the bottom of the barrel has higher rotating speed and pressure intensity. And the thickness of one side of the second water stirring component 7 close to the center of the impeller 5 is smaller, and the contact area with the washing water is smaller, so that the stirring effect of the part on the washing water is weaker, and the washing water in the middle of the bottom of the bucket has slower rotating speed and larger pressure. Under the action of pressure difference, the washing water in the middle of the bottom of the barrel can diffuse and flow outwards, so that the washing water at the bottom of the inner barrel 4 is promoted to flow to the barrel wall, and the power of the washing water rising along the barrel wall is increased. Under the combined action of the first water stirring component 6 and the second water stirring component 7, the washing water at the bottom in the barrel can turn over towards the barrel wall and climb to the barrel opening along the barrel wall, so that the clothes in the barrel are driven to continuously and repeatedly roll upwards and then fall off, the friction degree of the clothes with the washing water and the barrel wall is increased, the deposition of parts and clothes is avoided, and the washing effect of the clothes is improved.

Further, the number of the second water stirring members 7 is multiple (two or more), and one ends of the second water stirring members 7 close to the center of the impeller 5 are gathered and connected, so that a large recess is prevented from being formed in the center of the impeller 5, and dirt which is not easy to clean is prevented from being deposited on the upper surface of the impeller 5.

Further, a plurality of second water-repelling members 7 are uniformly distributed on the pulsator 5 and are integrally formed on the pulsator 5, so that the occurrence of mounting gaps between the second water-repelling members 7 and the pulsator 5 and the accumulation of dirt are prevented.

To sum up, the utility model discloses a be provided with first water component 6 of dialling on rotary drum washing machine's the inside wall of interior bucket 4, be provided with second water component 7 of dialling on the impeller 5. The first/second water stirring components are in a structural arrangement form with non-uniform thickness distribution, so that the stirring degree of the washing water in the inner barrel 4 is inconsistent, the washing water is promoted to climb to a rotational flow along the barrel wall by utilizing the principle that pressure difference is generated due to different flow rates, and then clothes are promoted to roll upwards in the barrel, and the clothes are prevented from being deposited at the bottom of the barrel.

So far, the technical solution of the present invention has been described with reference to the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, a person skilled in the art can make equivalent changes or substitutions to the related technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
