Description

Technical Field

[0001] The utility model belongs to the field of washing equipment, and in particular relates to a washing barrel component of the washing equipment and the washing equipment. Background Art

[0002] As a convenient clothes washing device, washing machines have been widely used in people's lives. Existing washing machines are divided into drum washing machines and pulsator washing machines, among which pulsator washing machines are popular with users due to their good washing effect.

[0003] A pulsator washing machine usually includes a washing inner barrel and a pulsator, and the pulsator is arranged at the bottom of the washing inner barrel. When the pulsator washing machine is working, the rotation of the pulsator drives the washing water in the inner barrel to rotate, so as to wash the clothes to be washed in the inner barrel. The existing pulsator is usually a flat circular pulsator. When washing, impurities such as dirt and lint on the clothes are easily accumulated in the gap between the bottom surface of the pulsator and the inner barrel. It is impossible to effectively clean them by simply flushing. In addition, most of the clothes are covered on the pulsator during washing, which easily causes the clothes to be entangled and worn, and increases the energy consumption of the motor. In addition, dirt and lint are easy to breed bacteria when they are in a humid environment for a long time, which brings a bad user experience. If you want to clean it thoroughly, you need to remove the pulsator and scrub the dirt in the gap. This operation is relatively complicated, which further deteriorates the user experience.

[0004] In the prior art, a stirring type washing machine is also proposed, which uses an agitator with a certain size along the axial direction of the washing inner barrel to replace the pulsator in the pulsator washing machine. Figure 1 As shown, the agitator 1 in the existing agitator washing machine is often in an "inverted T" shape, consisting of an axial agitator 2 and a radial agitator 3, wherein the radial agitator 3 is arranged at the bottom of the washing tub 4 and has a larger radial dimension, and the clothes Y can only be washed in the area above the radial agitator 3 in the tub, which still cannot solve the problem that the gap between the agitator 1 and the bottom of the tub is easy to hide dirt and is difficult to clean. Some other agitator washing machines directly install the columnar agitator rod on the impeller at the bottom of the tub, and dirt and bacteria are still easy to accumulate between the impeller and the bottom of the tub.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0062] Embodiment 1

[0063] like Figure 2-17 As shown, this embodiment provides a washing tub 100 assembly of a washing device.

[0064] The washing tub 100 assembly includes a washing tub 100 and a water stirring member 200 rotatably disposed inside the washing tub 100. The water stirring member 200 extends upward from the bottom of the washing tub 100 and has a maximum radius section Dmax at a certain extension height. There is a spacing between the maximum radius section Dmax and the inner surface of the bottom of the tub constituting the washing space, and the height value of the spacing is greater than a preset value.

[0065] The washing tub 100 assembly of this embodiment includes the washing tub 100 and a water stirring member 200 rotatably disposed inside the washing tub 100. The water stirring member 200 can rotate relative to the washing tub 100, and can also rotate with the washing tub 100 in the same direction or in the opposite direction.

[0066] The water stirring member 200 is arranged in the washing tub 100 and extends upward from the bottom of the washing tub 100 along its axial direction. The water stirring member 200 has a maximum radius section Dmax at one of its extension heights. There is a spacing between the maximum radius section Dmax and the inner surface of the bottom of the washing tub 100 constituting the washing space, and the height value of the spacing is greater than a preset value. In the scheme of the present utility model, since the height value of the spacing is set to be greater than a preset value, the clothes C to be washed can be washed within the spacing, and dirt and grime are avoided from being hidden in the spacing. In the existing washing machine, a dial is provided in the washing tub, and the washing space in the washing machine refers to the area above the dial. However, the washing tub of the washing machine in this scheme is not provided with a dial, and an upwardly extending water stirring member is provided at the bottom of the washing tub. The washing space in this scheme refers to the area between the outer periphery of the water stirring member and the inner peripheral wall of the washing tub.

[0067] It should be noted that in the embodiment of the present invention, the radius of the water-stirring member 200 refers to the radius of a circle formed by taking a cross section of the water-stirring member 200 in a direction perpendicular to its rotation axis and taking the rotation center as the center at the maximum distance from the rotation center on the cross section.

[0068] In this solution, no pulsator is provided at the bottom of the washing tub 100 , and the clothes C to be washed directly contact the inner surface of the bottom of the washing tub 100 .

[0069] In the present embodiment, since a pulsator is not provided at the bottom of the washing tub 100 and a gap is provided between the maximum radius section Dmax and the inner surface of the bottom of the washing tub 100, during the process of washing clothes C, the water flow can flush the gap, thereby avoiding dirt accumulation between the water stirring member 200 and the bottom of the washing tub 100.

[0070] The solution of this embodiment also includes: the preset value is 10 cm. That is, the minimum distance between the maximum radius section on the water stirring member and the inner surface of the bottom of the washing tub is 10 cm, thereby ensuring that the clothes C have enough washing space.

[0071] More specifically, the washing tub includes a tub bottom 100-a disposed at the bottom and a tub body 100-b disposed above the tub bottom, and the maximum radius section of the water stirring member is disposed above the highest point of the tub bottom 100-a. That is, the maximum radius section is disposed in the tub body 100-b and is at a certain distance from the highest position of the tub bottom 100-a.

[0072] The solution of this embodiment also includes: the water stirring member 200 includes a mounting portion 210-1 coaxially arranged with the bottom of the barrel and a water stirring portion 240 arranged above the mounting portion 210-1, and the mounting portion 210-1 cooperates with the bottom of the barrel;

[0073] The water stirring portion 240 includes a support column 210 and a water stirring rib 220 disposed on the support column 210 along an extending direction of the support column, and the water stirring rib 220 extends toward the peripheral wall of the washing tub 100;

[0074] The support column 210 extends upward from the top of the assembly portion 210 - 1 , and the radius of the connection between the support column 210 and the assembly portion 210 - 1 is similar;

[0075] The maximum radius section Dmax is at a distance from the top end of the fitting portion 210 - 1 .

[0076] The central area of ​​the washing tub 100 is recessed downward to form a groove-like structure 250, and the assembly portion 210-1 is disposed in the groove-like structure 250, with its upper end protruding from the groove-like structure 250 and being higher than the inner surface of the tub bottom or being flush with the inner surface of the tub bottom;

[0077] The bottom surface of the groove-shaped structure is provided with an installation opening, and the stirring shaft passes through the installation opening and is inserted into the assembly part 210 - 1 to be connected with the water stirring part 240 ;

[0078] The support column 210 and the assembly portion 210 - 1 have the same radius at the connection point, and the two are integrally formed.

[0079] The water stirring portion 240 further includes a water stirring plate 230 , which is installed above the water stirring ribs 220 and at the extended end of the water stirring member 200 ;

[0080] The water stirring tray 230 has an extension height in the central axis direction of the washing tub 100 , and the maximum radius section Dmax is located at any extension height position of the water stirring tray 230 .

[0081] The water stirring ribs 220 first extend obliquely toward the edge of the mouth of the washing bucket 100, and then extend upward toward the mouth of the washing bucket in a direction parallel to the support column 210;

[0082] The length of the maximum radius section Dmax does not exceed the radius length of the washing tub.

[0083] In the scheme of this embodiment, the water stirring member 200 includes an assembly portion 210-1 coaxially arranged with the bottom of the barrel and a water stirring portion 240 arranged above the assembly portion 210-1. The water stirring portion 240 includes a support column 210 coaxially arranged with the bottom of the barrel, a water stirring rib 220 arranged on the outer periphery of the support column 210, and a water stirring plate 230 arranged at the end of the support column 210. That is, one end of the support column 210 is connected to the top of the assembly portion 210-1, and the other end extends upward. The water stirring plate 230 is arranged at its extended end. The water stirring rib 220 extends obliquely from the outer periphery of the connection between the support column 210 and the assembly portion 210-1 to the top of the washing barrel 100.

[0084] The support column 210 is cylindrical, and is coaxially arranged with the assembly portion 210 - 1 , and the support column 210 extends upward from the top of the assembly portion 210 - 1 . That is, the upper end of the assembly portion 210 - 1 is connected to the lower end of the support column 210 .

[0085] In a specific solution of this embodiment, the radius of the connection between the assembly part 210-1 and the support column 210 is the same, and the two are an integrally formed structure. Of course, in other solutions of this embodiment, the shape of the assembly part 210-1 can be other shapes besides cylindrical, and its inner diameter is slightly larger than the inner diameter of the support column 210, which is within the protection scope of this utility model.

[0086] In a specific solution of this embodiment, the support column 210 is a cylindrical structure, and the radius of the cylindrical structure is the same along its extension direction. The support column 210 extends upward from the top of the assembly portion 210-1, and a water stirring plate 230 is provided at the extension end. In the solution of this embodiment, the maximum radius section Dmax is provided on the water stirring plate 230.

[0087] In another specific scheme of the present embodiment, the support column 210 includes two parts, namely, a first extension section 211 and a second extension section 212 connected to each other. The first extension section 211 extends upward from the bottom of the washing tub 100, and its side wall forms a second guide surface 214. The second extension section 212 extends upward from the first extension section 211, and the radius of the second extension section 212 gradually increases with the increase of height, and its side wall forms a first guide surface 213. In other words, the inner diameters of the first extension section 211 and the second extension section 212 are not the same. The radius of the first extension section 211 remains unchanged, and the radius of the second extension section 212 gradually increases with the increase of height. By providing the first extension section 211 and the second extension section 212, the angle between the side wall of the upper end of the support column 210 and the lower surface of the water stirring plate 230 is greatly increased, thereby effectively reducing the problem of a cleaning dead angle between the upper end of the support column 210 and the lower surface of the water stirring plate 230 that the clothes C cannot touch. In this solution, the contact area between the end cap and the support column 210 is increased, so that the two are fixed more firmly. In this solution, the assembly portion 210-1, the first extension section 211 and the second extension section 212 are integrally formed, and the assembly portion 210-1 and the first extension section 211 have the same radius.

[0105] The sealing groove 210-4 includes a first section and a second section with increasing diameters from top to bottom. The lower end of the plug-in portion is provided with a limiting protrusion protruding from the outer wall of the lower end of the plug-in portion in a direction away from the axis of the water-stirring member 200, and the limiting protrusion is engaged at the junction between the first section and the second end.

[0106] Preferably, the inner wall of the first section and the inner wall of the second section of the sealing groove 210-4 are transitionally connected by a conical surface that is inclined from top to bottom in a direction away from the axis of the water stirring member 200, the shape of the limiting protrusion is adapted to the shape between the first section and the second section of the sealing groove 210-4, the outer peripheral surface of the limiting protrusion is in contact with the inner wall of the second section, and the top of the limiting protrusion is in contact with the conical surface between the first section and the second section of the limiting groove. Preferably, the bottom of the limiting protrusion is set as a conical surface with a gradually decreasing outer diameter from top to bottom, and the outer diameter of the bottom of the limiting protrusion is smaller than the inner diameter of the notch of the sealing groove 210-4.

[0107] In this embodiment, a sealing ridge extending along the circumference of the plug-in portion is provided in the middle of the plug-in portion, and the plug-in portion elastically abuts against the inner wall of the first section of the sealing groove 210-4 through the sealing ridge. Preferably, the sealing ridge extends along the circumference of the plug-in portion and is provided with multiple circles arranged at intervals along the axial direction of the plug-in portion.

[0108] Preferably, in this embodiment, the sealing ridge is inclined upward along the extension direction away from the axis of the water-stirring member 200 to improve the smoothness of the insertion of the sealing cover 210 - 5 .

[0109] The washing device is provided with a driving device, and a stirring shaft is installed on the driving device. A mounting opening is provided on the bottom of the washing tub 100, and the mounting opening is an opening that penetrates the bottom of the tub. The stirring shaft of the driving device is inserted into the interior of the assembly part 210-1 through the mounting opening and connected to the water stirring part 240. When the washing device performs a washing operation, the stirring shaft drives the mounting part to rotate the water stirring part 240.

[0110] In one scheme of the present embodiment, the bottom of the washing barrel has a groove-like structure extending downward, and a mounting opening is provided on the bottom surface of the groove-like structure. The stirring shaft of the driving device is inserted through the mounting opening into the assembly part 210-1 vertically arranged in the groove-like structure and connected to the water stirring part 240. The upper end of the assembly part 210-1 is arranged flush with the inner surface of the barrel bottom. That is to say, in this scheme, the lower end of the support column 210 is also flush with the inner surface of the barrel bottom. Since the water stirring rib 220 is arranged on the support column 210 and connected to one end of the support column 210, the lower end of the water stirring rib 220 abuts against the inner surface of the barrel bottom.

[0111] like Figure 7As shown, in another scheme of this embodiment, the bottom of the washing barrel is almost flush with the horizontal plane, and the central area of ​​the bottom of the washing barrel is recessed downward to form a groove-like structure 250. A mounting opening is provided on the bottom surface of the groove-like structure 250, and the stirring shaft of the driving device is inserted through the mounting opening into the assembly part 210-1 vertically arranged in the groove-like structure and connected to the water stirring part 240. Among them, the assembly part 210-1 is vertically arranged to protrude from the groove-like structure 250 and is higher than the inner surface of the barrel bottom. The assembly part includes two parts, namely, a first part and a second part connected to each other. Among them, the first part is vertically arranged in the groove-like structure and connected to the stirring shaft, and the second part protrudes from the inner surface of the barrel bottom and is connected to the support column 210. In this scheme, the radius of the groove-like structure 250 is slightly larger than the radius of the assembly part. More specifically, the radius of the groove-like structure 250 is slightly larger than the radius of the assembly part installed therein, that is, the radius of the first part.

[0112] That is to say, in this solution, the upper end of the second part of the assembly portion is at a certain distance from the inner surface of the barrel bottom, so the lower end of the water stirring rib 220 is also at a certain distance from the inner surface of the barrel bottom.

[0113] In the solution provided in this embodiment, the lowermost end of the water stirring rib 220 does not directly contact the bottom of the washing tub, but is spaced between the assembly portion and the inner surface of the bottom of the tub. Therefore, during use, when the stirring shaft drives the water stirring member to rotate, the water stirring rib 220 does not rub against the inner surface of the bottom of the washing tub, thereby not increasing the friction between the water stirring member and the bottom of the washing tub when rotating.

[0114] Of course, in other solutions of this embodiment, the bottom of the washing tub may not have a groove structure, and the installation opening may be directly opened on the surface of the bottom of the tub, and the assembly portion may be directly protruded from the inner surface of the bottom of the tub. In other words, the lower end of the supporting rib is at a certain distance from the inner surface.

[0115] The water stirring rib 220 in this embodiment is a plate-like structure with one end arranged on the support column 210 along the extending height direction of the support column 210 and the other end extending outwardly along the radial direction of the support column 210 .

[0116] It is worth noting that the extension length of the water-stirring rib 220 is different at different height positions of the support column 210. In other words, the outer contour of the water-stirring rib 220 is an arc.

[0117] It is worth noting that the water stirring rib 220 in this solution first extends obliquely toward the edge of the barrel opening of the washing tub 100, and at the end of the extension, it tends to extend parallel to the support column 210 toward the upper side of the barrel opening of the washing tub 100. The end of the extension abuts against the water stirring plate 230. In the above preferred embodiment, the initial inclination angle is the angle between the barrel bottom of the washing tub 100 and the straight line connecting the end of the water stirring rib 220 and the barrel opening edge of the washing tub 100.

[0118] In a specific solution of this embodiment, the water stirring member 200 includes a plurality of water stirring ribs 220, and the plurality of water stirring ribs 220 are arranged at equal intervals along the circumference of the support column 210. The ends of the water stirring ribs 220 at the same height position of the support column 210 form a circle, and the radius of the circle formed by the ends of the water stirring ribs 220 increases along the upward extension direction of the support column 210. The radius of the circle formed by the ends of the water stirring ribs 220 may increase gradually, or may increase gradually first and then decrease, or the radius may have a small change range at the beginning and then a large change range.

[0119] For example, the dimension of the water stirring rib 220 along the radial direction of the washing tub 100 increases first and then decreases from the lower end to the upper end. As a specific embodiment, the cross-sectional shape of the water stirring rib 220 along the radial direction parallel to the washing tub 100 is close to a shuttle shape, and the peripheral edge of the water stirring rib 220 extends from bottom to top, and the angle between the extension direction and the vertical direction gradually decreases, so that the peripheral edge of the water stirring member 200 forms a curve that bends toward the barrel wall of the washing tub 100. The upper end of the peripheral edge of the water stirring rib 220 coincides with the periphery of the water stirring tray 230. In this solution, the number of water stirring ribs can be set according to demand.

[0120] The water-stirring ribs 220 have the above-mentioned structure, which can form a Coanda effect during washing, driving the water flow to flow along the outer peripheral edge of the water-stirring ribs 220, so that in the area close to the axis of the washing tub 100, the water flow has a flow tendency to fit the outer peripheral edge of the water-stirring ribs 220, and as the height increases, the flow direction of the water flow is closer to upward rather than flowing toward the periphery. In this way, the lifting force of the water flow on the clothes C in the area close to the axis can be enhanced, driving the clothes C to move upward along the second guide surface 214 to the first guide surface 213, and finally forming a circular motion path.

[0121] It can be understood that the clothes C moving along the bottom of the barrel toward the central area can also be lifted along the outer edge of the water-stirring ribs 220 after contacting the water-stirring ribs 220. After moving to the maximum radius section Dmax of the water-stirring member 200, they move toward the periphery under the action of inertia and centrifugal force, and finally fall to the bottom of the barrel along the wall of the washing barrel 100.

[0122] In the above structure, the radius of any horizontal section of the water stirring portion 240 specifically refers to the distance from the farthest end of the water stirring rib 220 from the axis to the central axis on the horizontal section. When the number of the water stirring ribs 220 is an even number, the length of the line connecting the farthest ends of two relative water stirring ribs 220 from the axis is the diameter of the horizontal section of the water stirring portion 240. When the number of the water stirring ribs 220 is an odd number, there are no relatively arranged water stirring ribs 220, and at this time, the horizontal section of the water stirring portion 240 does not form an axisymmetric figure, but the diameter of the horizontal section of the water stirring portion 240 is still twice the radius determined above.

[0123] In another specific embodiment, the water stirring ribs extend spirally along the side wall surrounding the support column. In this case, the horizontal cross section of the water stirring portion may not form a regular geometric shape, but the radius of the horizontal cross section of the water stirring portion is still the distance from the farthest end of the water stirring ribs from the axis to the central axis on the cross section.

[0124] In the above solution, the lowermost end of the water stirring rib 220 is not in direct contact with the bottom of the washing tub 100, but is spaced apart from the inner surface of the bottom. Therefore, during use, when the stirring shaft drives the water stirring member 200 to rotate, the water stirring rib 220 will not rub against the inner surface of the bottom of the washing tub 100, thereby not increasing the friction between the water stirring member 200 and the bottom of the washing tub 100 when rotating. In addition, it can also avoid the existence of a cleaning dead angle between the water stirring rib 220 and the bottom of the tub.

[0125] In the present embodiment, the water stirring tray 230 has an extended height in the central axis direction of the washing tub 100 , and the maximum radius section Dmax is located on the water stirring tray 230 .

[0126] In a specific solution of this embodiment, the water stirring ribs 220 are umbrella-shaped structures, the support column 210 is equivalent to the umbrella handle, and the water stirring plate 230 is equivalent to the umbrella cover. In the water stirring member 200, the radius of the water stirring plate 230 decreases from bottom to top, and the maximum radius section Dmax on the water stirring plate 230 is located at the lowermost end of the water stirring plate 230. Since the water stirring ribs 220 are arranged at intervals along the circumference of the support column 210, the uppermost end of the water stirring ribs 220 is arranged below the water stirring plate 230.

[0127] The upper surface of the water stirring plate 230 is a curved surface with a middle area higher than the outer peripheral area. In order to further increase the contact area between the water stirring member 200 and the laundry C to be washed, a protruding stirring portion 231 is provided on the curved surface.

[0128] like Fig. 9 As shown, the stirring part 231 is in the shape of a rocket, one end of the rocket body is arranged near the central area of ​​the upper surface of the water stirring tray 230, and the end of the rocket head is arranged to extend toward the edge of the water stirring tray 230. In this solution, a plurality of stirring parts 231 are arranged at intervals on the upper surface of the water stirring tray 230. Therefore, during the washing process of the clothes C, the stirring parts 231 rotate with the water stirring member 200 to stir the washing water above the water stirring tray 230, and the clothes C can be fully rubbed against the surfaces of the plurality of stirring parts 231, so that the clothes C are washed more cleanly.

[0129] In a preferred embodiment, the uppermost end of the water stirring rib 220 is fixedly abutted against the inner surface of the water stirring plate 230 .

[0130] It is worth noting that, in the present embodiment, the distance between the outermost contour of the water-stirring rib 220 and the mounting column is smaller than the radius of the maximum radius section Dmax of the water-stirring plate 230 .

[0131] It should be noted that in the embodiment of the present invention, the maximum radius section refers to the radius of the horizontal cross section of the water stirring portion 240. The water stirring portion 240 is taken along the horizontal direction (see Fig.10 ), the distance from the farthest point on the horizontal section to the center of rotation.

[0132] Specifically, if the horizontal cross section of the water stirring portion 240 is Fig.11 If the horizontal cross section of the stirring portion 240 is Figures 12 to 17 For a non-circular shape as shown, the radius is the distance R2 from the farthest point on the cross section from the center of rotation to the center of rotation (i.e. the position marked with "×" in the figure).

[0133] In the solution of this embodiment, the maximum radius section Dmax can be set at any extension height position of the water stirring tray 230. The water stirring tray 230 can be divided into three parts along the extension direction of the height of the water stirring tray 230, namely the lower area, the middle area and the upper area, and the maximum radius section Dmax can be set in any area of ​​the lower area, the middle area and the upper area. That is to say, along the extension direction of the height of the water stirring tray 230, the radius of the end cover can gradually decrease, can also gradually increase, or can first gradually increase and then gradually decrease.

[0134] For example, the water stirring plate 230 is composed of two parts. One part is a cylindrical structure that abuts against the water stirring rib 220 and extends upward, and the other part is a conical structure whose inner diameter gradually decreases at the end of the cylindrical structure. In this solution, the maximum radius section Dmax is still located in the lower area of ​​the water stirring plate 230.

[0135] For example, Figure 4 As shown, the water stirring plate 230 is a disc-shaped structure arranged above the water stirring ribs.

[0136] For example, the water stirring plate 230 is a structure in which the radius gradually increases from bottom to top and then gradually decreases. In this solution, the maximum radius section Dmax is equivalent to being located in the middle area of ​​the water stirring plate 230.

[0137] For example, Figure 6 As shown, the water stirring plate 230 is composed of two parts. One part is a truncated cone structure that abuts against the water stirring rib 220 and extends upward, and the other part is a conical structure whose inner diameter gradually decreases at the end of the truncated cone structure. In this solution, the maximum radius section Dmax is still located in the lower area of ​​the water stirring plate 230.

[0138] The water stirring plate can also be Figure 5 Irregular shape shown.

[0139] In other solutions of this embodiment, the shape of the water stirring plate 230 may also be regular or irregular. For example, the cross section of the water stirring plate 230 at a certain height position may be a circle, an ellipse, a triangle, a square, a rectangle, a polygon with equal sides, a polygon with unequal sides, or an irregular shape composed of semicircles with different radii.

[0140] Of course, since the water stirring plate 230 has a certain thickness, the cross-sectional shapes at different thickness positions may be different.

[0141] The solution of this embodiment also includes: the projection of any position of the outer edge of the water stirring rib 220 vertically to the bottom of the barrel is directly located on the inner surface of the bottom of the washing barrel 100.

[0142] With the vertical distance between any position on the outer edge of the water stirring rib 220 and the support column 210 as the radius, draw a circle with the axis of the support column parallel to the outer edge as the center, and the projection of any position on the circumference of the circle vertically to the bottom of the barrel is directly located on the inner surface of the bottom of the washing barrel 100.

[0143] The projection of any position of the maximum radius section Dmax vertically toward the bottom of the barrel is directly located on the inner surface of the bottom of the washing barrel 100.

[0144] In the scheme of this embodiment, the outer edge of the water stirring rib 220 is arc-shaped, and the projection of the outer edge at any position vertically to the bottom of the barrel is directly and unobstructedly located on the inner surface of the bottom of the washing barrel 100. Any position of the outer edge of the water stirring rib 220 extends vertically downward to the bottom of the inner barrel, and contacts the inner surface of the inner barrel bottom. In other words, the position of the projection of the edge of the maximum radius of the water stirring rib 220 vertically to the bottom of the barrel and the straight area between the outer periphery of the support column 210 are not provided with a dial. In this scheme, there is no bottom disc-shaped stirring part.

[0145] Since the water-stirring ribs 220 in this embodiment are arranged at circumferential intervals along the support column 210, a circle is drawn with the vertical distance between any position of the outer edge of the water-stirring rib 220 and the support column 210 as the radius and the axis of the support column parallel to the outer edge as the center. The projection of any position on the circumference of the circle vertically to the bottom of the barrel is directly located on the inner surface of the bottom of the washing barrel 100.

[0146] In the scheme of this embodiment, a circle is drawn with the vertical distance between the edge where the maximum radius of the water-stirring rib 220 is located and the support column 210 as the radius, and the center of the support column 210 parallel to the edge where the maximum radius of the water-stirring rib 220 is located as the circle. No dial is set in the circular area formed between the position where the circular edge is projected vertically to the bottom of the barrel and the outer periphery of the support column 210.

[0147] Similarly, the circular area formed by the edge of the maximum radius segment Dmax on the water stirring plate 230, where the projection of the circular edge vertically to the bottom of the barrel is located, and the circular area formed between the outer periphery of the support column 210, is not provided with a dial.

[0148] The solution of this embodiment also includes: the depth of the washing tub 100 is H, and there is a distance between the maximum radius section Dmax on the water stirring plate 230 of the water stirring member 200 and the inner surface of the bottom of the tub, and the height of the distance is h. The above distance h and the depth H of the washing tub 100 satisfy: h / H ≥ 1%. Through a large number of tests conducted in advance, it is found that when the distance h and the depth H of the washing tub 100 satisfy the above proportional relationship, the effect of preventing dirt and grime from accumulating between the water stirring member 200 and the washing tub 100 is the best.

[0149] Of course, in other solutions of this embodiment, the ratio of the height h of the interval to the height H of the washing tub 100 may also be greater than or equal to other values.

[0150] In this solution, in order to ensure the washing space of the clothes C, the maximum radius section Dmax on the water stirring tray 230 cannot be too large. Specifically, the length of the maximum radius section Dmax can be set to not exceed the radius length of the washing tub.

[0151] The solution provided in this embodiment, by providing the water stirring member 200 in the washing tub 100, can not only prevent dirt from being hidden between the water stirring member 200 and the bottom of the tub, thus improving the user experience, but also save energy consumption.

In addition, this solution enables the clothes C to be washed within the distance between the maximum radius section Dmax of the water stirring member 200 and the inner surface of the bottom of the washing tub 100.
