Description

Technical Field

[0001] The present invention belongs to the technical field of household appliances, and in particular, relates to a control method for a washing device and the washing device. Background Art

[0002] As a washing device for washing clothes, 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 cleaning 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] A stirring washing machine is also proposed in the prior art, 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 size in the radial direction. During washing, the clothes Y can only be washed in the area above the radial agitator 3 in the tub, and 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 cannot be solved.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a method and a washing device for washing clothes. By extending the mounting portion outward to the inner surface of the barrel bottom of the inner peripheral wall of the barrel to form a washing surface, the clothes are washed in the washing space formed by the washing surface and the space above the washing surface, so that the radius of the bottom end surface of the water stirring member is small enough, and the connection between the water stirring member and the barrel bottom without an impeller is realized, so that more washing space is exposed inside the washing barrel for washing clothes, so as to avoid the problem that dirt and grime are easily hidden between the existing stirring device and the barrel bottom and are difficult to clean, and to avoid clothes covering the impeller during washing, reduce the entanglement and wear of clothes and reduce the energy consumption of the motor, and fully wash the clothes.

[0056] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but are intended to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0057] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0058] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0059] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0060] like Figure 2-20 As shown, an embodiment of the present invention provides a washing tub 100 assembly of a washing device, and a washing device having the washing tub 100 assembly. The washing device may be a washing machine, a washer-dryer, a care machine, or other washing device with a clothes washing function. When the washing device is a washing machine, the washing machine is preferably a pulsator washing machine.

[0061] Specifically, the washing tub 100 assembly includes the washing tub 100 and the water stirring member 200 rotatably disposed inside the washing tub 100. The washing device also includes a driving device, which is transmission-connected to the washing tub 100 and the water stirring member 200.

[0062] More specifically, the output shaft of the driving device is respectively connected to the stirring shaft 300 and the dehydrating shaft. The stirring shaft 300 is connected to the water stirring member 200 and relatively fixed, and is used to drive the water stirring member 200 to rotate. The dehydrating shaft is fixed to the bottom 100-3 of the washing tub 100, and is used to drive the washing tub 100 to rotate.

[0063] During the washing process, the driving device drives the water stirring member 200 to rotate alone, or drives the water stirring member 200 and the washing tub 100 to rotate in opposite directions, so as to utilize the relative rotation trend between the water stirring member 200 and the washing tub 100 to stir the clothes C and the washing water in the tub, thereby achieving a cleaning effect on the clothes C. During the dehydration process, the driving device drives the water stirring member 200 and the washing tub 100 to rotate synchronously at a high speed, and utilizes centrifugal force to spin dry the clothes C in the tub.

[0064] However, when the lint and dirt shed from the clothes C during the washing process are mixed into the washing water, if there is a relatively narrow gap structure between the water stirring member 200 and the washing tub 100, these lint and dirt are easily hidden in the gap structure and are difficult to be taken out by the impact force of the water flow during the washing process, and the user needs to manually disassemble the water stirring member 200 for cleaning. If the user does not clean it for a long time, a large amount of dirt will accumulate in the gap between the water stirring member 200 and the washing tub 100, which is easy to breed bacteria, causing the problem of secondary contamination of the clothes C.

[0065] The present embodiment provides a washing tub assembly of a washing device, and a washing device having the washing tub 100 assembly, which is used to solve the problem that there is a dead corner between the water stirring device and the washing tub 100 of the existing equipment where dirt and grime are hidden and difficult to clean.

[0066] Specifically, the washing tub 100 assembly described in this embodiment includes a washing tub 100, a water stirring member 200, and a stirring shaft 300 that drives the water stirring member 200 to rotate relative to the washing tub 100. The bottom 100-3 of the washing tub 100 has a mounting portion 100-2 rotatably assembled with the stirring shaft 300. The stirring shaft 300 passes through the mounting portion 100-2 and is connected to the water stirring member 200. The bottom of the water stirring member 200 is arranged opposite to the mounting portion 100-2. The radius of the bottom end face of the water stirring member 200 is equal to or substantially equal to the radius of the mounting portion 100-2. The inner surface of the bottom of the washing tub from the washing tub mounting portion 100-2 to the inner peripheral wall is exposed as a washing surface. The washing surface and the internal space of the washing tub above the washing surface form a washing space. Figure 2 As shown, the washing method is: controlling the water stirring member to rotate relative to the bottom of the barrel so that the clothes are washed in the washing space.

[0067] The water-stirring member 200 and the washing tub 100 described in the present embodiment have the above-mentioned matching structure. Compared with the traditional pulsator washing machine or the agitator washing machine with a radial agitator, the radius of the bottom end face of the water-stirring member 200 of the present application is small enough to achieve a connection between the water-stirring member 200 and the tub bottom 100-3 without an impeller, so that the washing tub has no bottom disc-shaped stirring portion, thereby exposing more washing space inside the washing tub 100 for washing clothes, and can avoid the problem that dirt and grime are easily hidden between the stirring device and the tub bottom 100-3 of the existing washing equipment, which is difficult to clean. It can prevent clothes from covering the impeller during washing, reduce the entanglement and wear of clothes, reduce the energy consumption of the motor, and can fully wash the clothes.

[0068] The mounting portion 100-2 of the present application is for the stirring shaft 300 to pass through and connect with the water stirring member 200. Since the radius of the stirring shaft 300 is small enough, in order to adapt to the stirring shaft 300, the radius of the mounting portion 100-2 is also small enough. The radius of the bottom end face of the water stirring member 200 is set to be equal to or substantially equal to the radius of the mounting portion 100-2. Then, the radius of the bottom end face of the water stirring member 200 will be small enough. In the prior art, the radius of the impeller set on the barrel bottom 100-3 is much larger than the radius of the mounting portion 100-2. Therefore, it can be considered that the barrel bottom 100-3 of the present application has no impeller, and there is no impeller connection between the water stirring member 200 of the present application and the barrel bottom 100-3, so that most of the area of ​​the barrel bottom 100-3 is exposed to form a washing surface 100-31 that is in direct contact with the clothes, so that the washing surface 100-31 formed by the barrel bottom 100-3 is in contact with the clothes during washing, which can be distinguished from the direct contact between the clothes and the impeller during washing in the prior art.

[0069] It should be noted that the radii of the various components involved in the present application are all radii along the radial direction of the washing tub 100; the water stirring member 200 of the present application rotates relative to the bottom of the tub, and during washing, the water stirring member 200 rotates and the washing tub does not rotate, or the water stirring member rotates and the washing tub also rotates. When only the water stirring member rotates, the water stirring member rotates along the circumference of the washing tub to form a rotating water flow.

[0070] The radius of the bottom end surface of the water stirring member 200 is substantially equal to the radius of the mounting portion 100-2, including that the radius of the bottom end surface of the water stirring member 200 is slightly larger than the radius of the mounting portion 100-2, or that the radius of the bottom end surface of the water stirring member 200 is slightly smaller than the radius of the mounting portion 100-2;

[0071] Further, the mounting portion 100-2 is a mounting through hole 100-21 provided on the barrel bottom 100-3. The mounting through hole 100-21 may be circular, square, etc. The mounting through hole 100-21 passes through the barrel bottom 100-3. The way in which the water stirring member 200 is connected to the mounting through hole 100-21 includes: when the bottom end face of the water stirring member 200 is equal to or greater than the radius of the mounting through hole 100-21, the bottom end face of the water stirring member 200 is overlapped on the upper end face of the mounting through hole 100-21 and abuts against the upper end face of the mounting through hole 100-21; or, when the bottom end face of the water stirring member 200 is smaller than the radius of the mounting through hole 100-21, the bottom end face of the water stirring member 200 is inserted into the mounting through hole 100-21.

[0072] Further specifically, the stirring shaft 300 of the present application extends from the mounting through hole 100-21 to the inside of the washing barrel 100, and the stirring shaft 300 is coaxially arranged with the washing barrel 100; the water stirring member 200 of the present application includes an assembly portion 210-1 coaxially arranged with the barrel bottom 100-3 and a support column arranged above the assembly portion, and the support column 210 is assembled with the stirring shaft 300 through the assembly portion 210-1; the assembly portion 210-1 of the water stirring member 200 is sleeved on the upper end of the stirring shaft 300, and the assembly portion 210-1 and the stirring shaft 300 are key-connected, and the assembly portion 210-1 and the stirring shaft 300 are specifically circumferentially positioned by a spline. Preferably, the assembly portion 210-1 of the water stirring member 200 and the stirring shaft 300 are axially positioned by a clamping structure or screws.

[0073] The assembly part 210-1 corresponds to the installation through hole 100-21 in the middle of the barrel bottom 100-3. The inner side of the barrel bottom 100-3 is provided with an installation groove 100-1. The lower end of the assembly part 210-1 can be rotatably inserted into the installation groove 100-1. The installation groove 100-1 is arranged around the stirring shaft 300. The installation through hole 100-21 is arranged on the bottom of the installation groove 100-1. The stirring shaft 300 passes through the installation groove 100-1 and extends to the inside of the washing barrel 100. The radius of the bottom of the assembly part 210-1 is adapted to the radius of the installation groove 100-1.

[0074] In an embodiment of the present invention, the water stirring member 200 has a maximum radius at a certain distance from the washing surface 100-31;

[0075] The washing method is as follows: the water stirring member 200 rotates so that the clothes can be washed in the washing space below the maximum radius of the water stirring member 200, and / or the clothes are guided from the washing space below the maximum radius of the water stirring member 200 to the washing space above, and washed in the washing space above the maximum radius of the water stirring member 200.

[0076] In the embodiment of the present invention, the rotation of the water stirring member 200 can form a rotating water flow. Depending on the intensity of the rotating water flow and the water level in the washing tub 100, the clothes can be washed below the maximum radius of the water stirring member 200 or above the maximum radius of the water stirring member 200, thereby achieving sufficient washing of the clothes.

[0077] Specifically, the radius of the mounting portion 210-1 is the minimum radius of the water stirring member 200 below the maximum radius of the water stirring member 200, so that the radius of the mounting portion 210-1 is small enough to expose most of the area of ​​the barrel bottom 100-3 to form a washing surface 100-31 that contacts the clothes.

[0078] The assembly part 210 - 1 may be cylindrical, may be a cylindrical shape with a radius that changes from top to bottom, or may be a cylindrical shape with a constant radius from top to bottom; the assembly part 210 - 1 has a cavity inside for inserting the stirring shaft 300;

[0079] It should be noted that the radius of the water stirring member 200 refers to the cross section of the water stirring member 200 taken along the horizontal direction (see Figure 5 ), the distance from the farthest point on the horizontal section to the center of rotation.

[0080] Specifically, if the cross section of the water stirring member 200 is Figure 6 If the cross section of the water stirring member 200 is Figures 7 to 12 For a non-circular shape as shown, the radius is the distance R 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).

[0081] The radius of any horizontal cross section of the water stirring member 200 specifically refers to the distance from the farthest end of the water stirring member 200 from the axis to the central axis on the horizontal cross section. When the number of the water stirring ribs 220 is an even number, the length of the line connecting the farthest ends of the two water stirring ribs 220 from the axis is the diameter of the horizontal cross section of the water stirring member 200.

[0082] When the number of water-stirring ribs 220 on the water-stirring component 200 is an odd number, there are no relatively arranged water-stirring ribs 220. At this time, the horizontal cross-section of the water-stirring component 200 does not constitute an axially symmetrical figure, but the radius of the horizontal cross-section of the water-stirring component 200 is still the distance from the farthest end of the water-stirring rib 220 on the cross-section from the axis to the central axis.

[0083] The maximum radius of the water stirring member 200 is disposed on the support column 210 , and the radius of the support column 210 below the maximum radius of the water stirring member 200 is greater than or equal to the radius of the mounting portion 210 - 1 .

[0084] The support column 210 may be columnar, specifically, Figure 1-15 As shown, the support column 210 may be in a columnar shape with a constant radius from bottom to top, and the radius of the support column 210 is set to be greater than or equal to the radius of the mounting portion 210 - 1 , so that the radius of the mounting portion 210 - 1 can be sufficiently small.

[0085] In the embodiment of the present invention, the radius of the water stirring member 200 decreases from the maximum radius, the washing space below the maximum radius of the water stirring member 200 is the first space 100a, and / or the washing space between the maximum radius and the minimum radius above the water stirring member 200 is the second space 100b;

[0086] The washing method is as follows: using a first guide surface 213 formed below the maximum radius of the water stirring member 200 to guide the clothes in the first space 100a to the maximum radius of the water stirring member 200, and / or using a third guide surface 215 formed between the maximum radius of the water stirring member 200 and the minimum radius above to guide the clothes at the water stirring member 200 to the second space 100b.

[0087] In the embodiment of the present invention, the washing space below the maximum radius of the water stirring member 200 is the first space 100a, and the washing space between the maximum radius and the minimum radius above the water stirring member 200 is the second space 100b;

[0088] Specifically, a first guide surface 213 extending from bottom to top and away from the outer periphery of the axis of the washing tub 100 is formed below the maximum radius of the water stirring member 200; a third guide surface 215 extending from bottom to top and close to the axis of the washing tub 100 is formed between the maximum radius of the water stirring member 200 and the minimum radius above;

[0089] After guiding the clothes in the first space 100a to the maximum radius of the water stirring member 200 by the first guiding surface 213, the clothes are then guided in the peripheral direction away from the axis of the washing tub 100, and the clothes at the maximum radius of the water stirring member 200 are guided into the second space 100b by the third guiding surface 215, and the clothes are guided upward and close to the axis of the washing tub 100;

[0090] By setting the first guide surface 213, the clothes C can move from the central area to the periphery below the maximum radius Dmax of the water stirring member 200, and move a certain distance to the periphery, and the clothes C will fall under the action of gravity and the water flow. In this way, the effect of the water stirring member 200 rotating to drive the clothes C to move to the periphery and flip during the washing process is enhanced, thereby improving the washing effect and preventing the clothes C from gathering at the center and getting tangled.

[0091] More specifically, the clothes can be divided into a first part of clothes and a second part of clothes. The rotating water stirring member 200 forms a rotating water flow, and the rotating water flow causes the clothes moving toward the center of the barrel bottom 100-3 to roll upward and contact the first guide surface 213. The first guide surface 213 guides the clothes to the maximum radius of the water stirring member 200, and then guides the first part of clothes to the peripheral direction away from the axis of the washing barrel 100, so that the clothes are turned over and thrown down to the barrel bottom 100-3.

[0092] Under the action of the rotating water flow, the third guide surface 215 guides the second part of the clothes at the maximum radius of the water stirring member 200 into the second space 100b, and guides the second part of the clothes upward and close to the axis of the washing tub 100 to the minimum radius above, and then flips the clothes and throws them down to the bottom 100-3 of the tub;

[0093] Under the guidance of the rotating water flow, the first guide surface 213 and the third guide surface 215, the clothes move upward from the washing surface 100-31 of the barrel bottom 100-3, turn over, and then fall to the washing surface 100-31 of the barrel bottom 100-3, forming a circulation path.

[0094] See also Fig.16 and Fig.17 During washing, the circulation path of the clothes moving below the maximum radius Dmax of the water stirring member 200 includes: the clothes move toward the central area along the bottom 100-3 of the washing tub 100, move upward along the side of the water stirring member 200 in the central area to below the maximum radius Dmax and then move toward the periphery, and move downward in the area close to the wall of the washing tub 100.

[0095] The distance h between the maximum radius Dmax of the water stirring member 200 and the bottom 100-3 is greater than 5 mm, thereby ensuring that the clothes C can be washed below the maximum radius Dmax. The depth of the washing tub 100 is H, and the 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 from accumulating between the water stirring member 200 and the washing tub 100 is the best.

[0096] like Figures 13 to 16 The structure satisfies that clothes can be washed in the first space 100a and the second space 100b respectively. It should be noted that the water stirring member 200 has several maximum radii distributed at intervals in the axial direction of the washing tub 100, and the maximum radius of the topmost water stirring member 200 is the maximum radius of the water stirring member 200.

[0097] The maximum radius of the stirring member 200 is located at the position of the supporting column 210 of the stirring member 200, including the maximum radius of the stirring member 200 being located at the top of the supporting column 210 of the stirring member 200; or, the maximum radius of the stirring member 200 is spaced from the top of the supporting column 210 of the stirring member 200.

[0098] As a specific implementation method, Figure 3 ,as well as Figures 13 to 15As shown, the water stirring member 200 has a single maximum radius Dmax in the height direction. Further, at least below the maximum radius Dmax, as the height increases, the distance between the side of the water stirring member 200 and the inner peripheral wall of the washing tub 100 decreases as the height increases.

[0099] It should be noted that the single maximum radius Dmax may refer to the water-stirring member 200 having the maximum radius Dmax at a specific height position, or may refer to the water-stirring member 200 having the maximum radius Dmax within a certain continuous height range.

[0100] In the first specific solution, the maximum radius Dmax of the agitating member 200 is set at the top of the agitating member 200, that is, the top surface of the agitating member 200 is the cross section with the largest radius, forming only the first space 100a and the first guiding surface 213.

[0101] In the second specific scheme, if Fig.13 As shown, the maximum radius Dmax of the water stirring member 200 is close to the top of the water stirring member 200, but has a certain distance from the top of the water stirring member 200. Specifically, the upper side surface of the water stirring member 200 at its maximum radius Dmax is an upwardly convex curved surface, the highest point of the curved surface forms the top of the water stirring member 200, and can form the first space 100a and the second space 100b, and is formed with a first guide surface 213 and a third guide surface 215.

[0102] In the third specific scheme, if Fig.14 and Fig.15 As shown, the maximum radius Dmax of the water-stirring member 200 is located in the middle of the water-stirring member 200 along the height direction.

[0103] In a detailed scheme, Fig.14 As shown, the distance between the side of the water stirring member 200 and the barrel wall of the washing tub 100 changes continuously in the height direction. Specifically, as the height increases, the radius of the water stirring member 200 gradually increases from the barrel bottom 100-3 of the washing tub 100 upward until the maximum radius Dmax is formed, and then the radius of the water stirring member 200 gradually decreases and finally reaches the top of the water stirring member 200, so that the first space 100a and the third space 100c can be formed, and the first guide surface 213 and the third guide surface 215 are formed.

[0104] In another detailed scheme, Fig.15As shown, the distance between the side of the water stirring member 200 and the barrel wall of the washing tub 100 has a sudden change at at least one height position. Specifically, as the height increases, the radius of the water stirring member 200 first gradually increases from the barrel bottom 100-3 of the washing tub 100 upwards, and when reaching a certain height, the radius suddenly increases to form the maximum radius Dmax, and then the radius of the water stirring member 200 remains constant within a certain height range, then suddenly decreases, and then continues to gradually decrease, and finally forms the top of the water stirring member 200. In this solution, the distance h from the maximum radius Dmax on the water stirring member 200 to the barrel bottom 100-3 of the washing tub 100 refers to the distance from the lowest height in the height range where the radius of the water stirring member 200 remains constant to the barrel bottom 100-3 of the washing tub 100, which can form the first space 100a and the second space 100b, and form the first guide surface 213 and the third guide surface 215.

[0105] As another specific implementation, Fig.16 As shown, the water stirring member 200 has a plurality of maximum radius points Dmax distributed at intervals in the axial direction of the washing tub 100. Specifically, as the height increases, the radius of the water stirring member 200 increases and decreases alternately, each time increasing to the same radius size and then decreasing, thereby forming a plurality of maximum radius points Dmax distributed at intervals, forming the first space 100a and the second space 100b, and forming the first guide surface 213 and the third guide surface 215.

[0106] In the specific scheme of this embodiment, the water stirring member 200 includes a water stirring plate 230 arranged perpendicularly to the axis of the support shaft. The support shaft is used to transmit the driving device connected to the washing device, so that the water stirring member 200 can be rotated under the drive of the driving device. The outer periphery of the water stirring plate 230 forms the maximum radius Dmax of the water stirring member 200, and the first guide surface 213 is formed on the lower side of the water stirring plate 230, extending horizontally or obliquely upward from the area close to the center of the water stirring plate 230 to the outer periphery; the upper side of the water stirring member 200 is formed with a protrusion 215a extending upward, the radius of the protrusion 215a decreases upward, and the third guide surface 215 is formed on the protrusion 215a.

[0107] The radius of the connection between the support shaft and the lower surface of the water stirring plate 230 is smaller than the radius of the water stirring plate 230; the first guide surface 213 includes at least a portion of the lower surface of the water stirring plate 230, and a transition curved surface for smooth transition is provided at the connection between the side wall of the support shaft and the lower surface of the water stirring plate 230, and the first guide surface 213 also includes the transition curved surface. The extended end of the first guide surface 213 coincides with the outer periphery of the water stirring plate 230.

[0108] The water stirring plate 230 is connected to the upper end of the support shaft. Specifically, the upper end of the support shaft is connected to the center of the lower surface of the water stirring plate 230, and the area of ​​the lower surface of the water stirring plate 230 that is not covered by the upper end surface of the support shaft forms the first guide surface 213. The side wall of the support shaft extends upward from the bottom of the washing tub 100 in a vertical direction or a nearly vertical direction until it is connected to the lower surface of the water stirring member 200.

[0109] The water stirring member 200 further includes a water stirring rib 220 protruding from the side wall of the support shaft. The water stirring rib 220 has a certain extension length along the axial direction of the washing tub 100 at the lower side of the water stirring plate 230. The upper end of the water stirring rib 220 is connected to the first guide surface 213. The bottom end of the water stirring rib 220 is connected to the side wall of the assembly portion 210-1 located in the washing tub 100. The bottom end of the water stirring rib 220 is separated from the barrel bottom 100-3 by the side wall of the assembly portion 210-1, or the bottom end of the water stirring rib 220 is connected to the bottom end of the side wall of the assembly portion 210-1 located in the washing tub 100.

[0110] Specifically, when the bottom end of the water-stirring rib 220 is separated from the barrel bottom 100-3 by the side wall of the assembly portion 210-1, the method described includes: after the clothes in the first space 100a move along the washing surface 100-31 toward the center of the barrel bottom 100-3, the clothes move upward along the outer edge of the water-stirring rib 220 to the first guide surface.

[0111] When the bottom end of the water stirring rib 220 is connected to the bottom end of the side wall of the assembly part 210-1 located in the washing barrel 100, the method includes: after the clothes in the first space 100a move along the washing surface 100-31 toward the center of the barrel bottom 100-3, the clothes are moved upward along the outer edge of the water stirring rib 220 to the first guide surface.

[0112] The protruding direction of the water stirring rib 220 coincides with the radial direction of the washing tub 100, or is at a certain angle to the radial direction of the washing tub 100. In this way, when the water stirring rib 220 rotates with the water stirring member 200, the water stirring rib 220 has a surface arranged opposite to the rotation direction, which can effectively stir the clothes C and the water flow in the tub. The upper end of the water stirring rib 220 is connected to the first guide surface 213, that is, the lower surface of the water stirring plate 230, which can prevent the existence of a dead corner between the water stirring rib 220 and the water stirring plate 230 that cannot contact the clothes C and is easy to hide dirt.

[0113] A plurality of water stirring ribs 220 are arranged at intervals along the circumferential direction on the side wall of the support shaft, and the plurality of water stirring ribs 220 are preferably arranged symmetrically with respect to the rotation axis. The clothes are mainly removed and move upward along the outer edge of the water stirring ribs 220, and the clothes C can also be washed in the interval area between two adjacent water stirring ribs 220, thereby contacting the two side surfaces of the water stirring ribs 220 and the area between the two water stirring ribs 220 on the side wall of the support shaft.

[0114] The side of the water stirring member 200 includes both the side wall of the support shaft and the surface of the water stirring rib 220 farthest from the rotation axis, and the radius of the water stirring member 200 is twice the distance between the farthest point on the water stirring rib 220 from the rotation axis and the rotation axis.

[0115] Furthermore, in this embodiment, the radial dimension of the water stirring ribs 220 along the washing tub 100 increases with increasing height, thereby forming a structure in which the distance between the side of the water stirring member 200 and the wall of the washing tub 100 decreases with increasing height.

[0116] As a specific embodiment, the upper end of the water stirring rib 220 is aligned with the outer periphery of the water stirring plate 230 away from the axis of the support shaft, so that the radial dimension of the water stirring rib 220 along the washing tub 100 is maximized as much as possible, which can enhance the stirring force of the washing water and improve the washing effect.

[0117] In the embodiment of the present invention, the minimum radius above the maximum radius of the water stirring member 200 is at a certain distance from the barrel opening of the washing tub 100, and the washing space between the minimum radius above the maximum radius of the water stirring member 200 and the barrel opening forms a third space 100c;

[0118] The washing method includes: when the water level in the washing tub 100 is higher than a set water level, the water stirring member 200 rotates to guide part of the clothes from the first space 100a and the second space 100b to the third space 100c for washing.

[0119] In the embodiment of the present invention, the washing tub 100 can accommodate clothes C for washing both above and below the maximum radius Dmax of the water-stirring member 200. On the one hand, the volume of the washing tub 100 that can accommodate clothes C is increased. On the other hand, the outer surface of the water-stirring member 200 can basically contact the clothes C to be washed and generate friction with the clothes C. By increasing the surface area in contact with the clothes C, the washing effect can be enhanced.

[0120] In a further embodiment, the height at which the maximum radius Dmax of the water stirring member 200 is located is set between the highest water level and the lowest water level of the washing device. In this way, when the washing device uses different water levels for washing, the water stirring member 200 rotates relative to the washing tub 100 to generate different water flow modes to drive the clothes C to move for washing.

[0121] At the lowest water level, the laundry may be washed in the first space 100a and the second space 100b, and at the highest water level, the laundry may be washed in the first space 100a, the second space 100b, and the third space 100c.

[0122] Specifically, the washing bucket 100 assembly of this embodiment is applied to washing equipment, such as Fig.17As shown, when operating at a low water level W1 lower than the maximum radius Dmax of the water stirring member 200, the laundry moves along a reverse circular path in the water.

[0123] In detail, during the washing process, relative rotation occurs between the water stirring member 200 and the washing tub 100, and the clothes move along the path indicated by the arrow in the figure in the first space 100a below the maximum radius Dmax of the water stirring member 200, move toward the central area along the bottom 100-3 of the washing tub 100, and then are lifted to the bottom of the first guide surface 213 along the water stirring ribs 220, and then move toward the periphery along the first guide surface 213, and then fall to the bottom 100-3 in the area close to the wall of the washing tub 100, forming a circular motion.

[0124] like Fig.18 As shown, when a high water level W2 higher than the maximum radius Dmax of the water stirring member 200 is used, in an area lower than the maximum radius Dmax of the water stirring member 200, the clothes move in the water along the above-mentioned circular path; and in an area at a minimum radius higher than the maximum radius of the water stirring member 200, the clothes are close to moving circumferentially along the washing tub 100, that is, the clothes are washed in the third space 100c.

[0125] In detail, during the washing process, the water stirring member 200 and the washing tub 100 rotate relative to each other, and in the area below the maximum radius Dmax of the water stirring member 200, the movement path of the clothes is basically the same as the movement path under the low water level W1. In the area above the minimum radius Dmax of the water stirring member 200, the clothes move alternately forward and reverse along the circumference of the washing tub 100100 as the water stirring member 200 rotates alternately forward and reverse.

[0126] In the above scheme, when different washing water levels are used, the water stirring member 200 can drive the clothes in the barrel to move in different ways for washing, providing a more diverse selection of washing methods. Moreover, in the area below the maximum radius Dmax of the water stirring member 200, since the clothes move along a reverse circular path, on the one hand, the turning of the clothes can be strengthened, the washing effect can be enhanced, and on the other hand, the problem that the existing pulsator washing machine easily drives the clothes to gather toward the center, causing the clothes to be entangled, can be avoided. It should be noted that the upper end of the water stirring rib 220 is connected to the first guide surface 213, and the first guide surface 213 in the first embodiment can be formed on the water stirring rib 220.

[0127] Embodiment 2

[0128] like Figure 19-21 As shown, the difference between the second embodiment and the first embodiment is that the upper end of the water stirring rib 220 is connected to the first guide surface 213 , and the first guide surface 213 can be formed on the support column 210 .

[0129] In this embodiment, the water-stirring member 200 includes an assembly portion 210-1 and a water-stirring portion 240 extending upward from the assembly portion 210-1. The assembly portion 210-1 is configured as a solid structure, and the water-stirring portion 240 is at least partially configured as a hollow structure. For example, the water-stirring portion 240 is a cavity configured from the top end axially toward the assembly portion 210-1.

[0130] Specifically, in this embodiment, the assembly part 210-1 is a solid column, which can increase the connection strength of the water stirring member 200. The water stirring part 240 has an integrally formed hollow structure, and the water stirring part 240 is formed on the top of the assembly part 210-1, and the assembly part 210-1 can also block the lower end of the hollow structure of the water stirring part 240.

[0131] As a specific embodiment, the water-stirring member 200 includes a support column 210, and a water-stirring rib 220 arranged on the side wall of the support column 210 and protruding along the radial direction or near radial direction of the support column away from the axis of the support column 210. The water-stirring rib 220 extends along the axial direction of the support column in the length direction, and extends in the width direction away from the peripheral direction of the support column. The water-stirring rib 220 can be arranged radially or deviate from the radial direction.

[0132] In this embodiment, the support column 210 includes an assembly portion 210-1 and a hollow column 210-8 coaxially connected to the upper portion of the assembly portion 210-1. The assembly portion 210-1 is a solid column, preferably a cylindrical body, and the hollow column 210-8 extends upward from the upper end surface of the assembly portion 210-1. The outer diameter of the connection between the hollow column 210-8 and the assembly portion 210-1 can be greater than the radius of the assembly portion 210-1, or less than or equal to the radius of the assembly portion 210-1; the outer peripheral wall of the hollow column 210-8 and the outer peripheral wall of the assembly portion 210-1 smoothly transition and extend upward.

[0133] The water stirring portion 240 has a horizontal cross section with the largest radius at a certain height from the upper end of the assembly portion 210-1. A water stirring plate 230 is provided at the top of the support column 210. The maximum radius Rmax of the water stirring portion 240 is formed by the outer periphery of the water stirring plate 230. The top surface of the water stirring plate 230 is a curved surface convex upward. A cavity 210-9 similar to the outer shape of the support column 210 is formed inside the hollow column 210-8.

[0134] Preferably, the water stirring ribs 220 are also configured as hollow structures.

[0135] Further preferably, the inner space of the water stirring rib 220 is connected to the cavity 210 - 9 inside the hollow column 210 - 8 .

[0136] Further preferably, the lower end of the water-stirring rib 220 at least partially extends to the outer peripheral wall of the assembly portion 210 - 1 and is integrally formed with the assembly portion 210 - 1 , thereby further strengthening the strength of the connection between the assembly portion 210 - 1 and the water-stirring portion 240 .

[0137] In this embodiment, the water stirring portion 240 is connected to the stirring shaft 300 rotatably passing through the bottom of the washing tub 100 through the assembly portion 210 - 1 , so that the water stirring member 200 can rotate relative to the washing tub 100 .

[0138] Specifically, the assembly part 210-1 and the stirring shaft 300 are circumferentially positioned by splines, rotate together, and are axially positioned by screws 210-7. In this embodiment, the assembly part 210-1 is provided with a spline groove 210-6 extending upwardly coaxially from the bottom end face of the assembly part 210-1, and the spline groove 210-6 is at least partially sleeved on the upper end of the stirring shaft 300 and key-connected with the stirring shaft 300. The spline groove 210-6 is formed on the assembly part 210-1 of the water stirring member 200.

[0139] In this embodiment, the top of the water stirring member 200 is provided with an opening communicating with the cavity 210-9 inside the hollow column, and the screw 210-7 enters the cavity 210-9 through the opening and downwardly connects with the stirring shaft 300 key-connected in the assembly portion 210-1, thereby axially fixing the water stirring member 200 with the stirring shaft 300. In order to prevent water from entering the cavity 210-9, a blocking component is installed at the opening.

[0140] Preferably, a sealing groove 210-4 is provided on the top of the water stirring member 200, and the sealing groove 210-4 is formed by being coaxially recessed downward from the top surface of the water stirring plate 230. An opening communicating with the mold cavity 210-9 is provided on the bottom of the sealing groove 210-4.

[0141] Specifically, the upper end of the assembly part 210-1 is provided with a through hole, preferably a threaded hole, the rod of the screw 210-7 passes through the top of the assembly part 210-1 and is tightened in the threaded hole, and the head of the screw 210-7 abuts against the top of the assembly part 210-1. The operator disassembles and assembles the screw 210-7 through the opening on the bottom of the sealing groove 210-4 and the cavity 210-9 of the hollow column 210-8. The screw is preferably a countersunk screw.

[0142] The sealing groove 210 - 4 is provided with a sealing cover 210 - 5 for sealing the upper end of the water stirring member 200 to prevent washing water from entering the interior of the water stirring member 200 .

[0143] Specifically, the sealing cover 210-5 includes a flat plate portion and an inserting portion. The flat plate portion covers the notch of the sealing groove 210-4 and is embedded in the top of the water stirring member 200. The inserting portion is inserted into the sealing groove 210-4 and has an interference fit with the sealing groove 210-4.

[0144] The top of the flat plate portion and the top of the water stirring member 200 are in the same plane.

[0145] 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.

[0146] 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.

[0147] 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.

[0148] 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 .

[0149] Specifically, in this embodiment, the side wall of the support shaft extends upward from the bottom surface of the washing tub 100 to a certain distance from the lower surface of the water stirring tray 230, extends upward toward the periphery from there, and finally connects with the lower surface of the water stirring tray 230 to form a first guide surface 213.

[0150] In the above solution, the support shaft includes a first extension section 211 and a second extension section 212 connected to each other, wherein the first extension section 211 extends upward from the bottom of the washing tub 100, and 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 the height, and its side wall forms a first guide surface 213. Through the above structure, the angle between the side wall of the upper end of the support shaft 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 shaft and the lower surface of the water stirring plate 230 that cannot be touched by clothes.

[0151] As a specific embodiment, the first extension section 211 extends upward in a straight line and is inclined outward at a small angle relative to the vertical direction, so that as the height of the support shaft increases, the distance between the first extension section 211 and the wall of the washing tub 100 gradually decreases. As the height increases, the angle between the first guide surface 213 and the vertical direction gradually increases, forming a curved surface that bends toward the side where the water stirring tray 230 is located.

[0152] In a specific solution, at the position where the first guide surface 213 and the first extension section 211 are connected, the two have the same inclination angle, thereby achieving a smooth transition connection.

[0153] In another specific solution, the first guide surface 213 has a slightly higher inclination angle at the position where the first guide surface 213 is connected to the first extension section 211, thereby forming an angle less than but close to 180° at the position where the first guide surface 213 is connected to the first extension section 211. In this way, when the clothes move on the first guide surface 213, a certain buffering effect can be exerted on the clothes, thereby strengthening the tendency of the clothes to move toward the periphery in a tumbling manner.

[0154] In a detailed scheme of this embodiment, the upper end of the side wall of the second extension section 212, that is, the extended end of the first guide surface 213 located at the periphery coincides with the periphery of the water stirring plate 230, so that the lower side surface of the water stirring plate 230 is completely covered by the upper end surface of the support shaft.

[0155] In the preferred embodiment of this embodiment, Fig. 22 As shown, the upper side surface of the water stirring tray 230 is a curved surface with a middle area higher than the outer peripheral area, and a protruding stirring portion 231 is provided on the curved surface. When the water level in the washing tub 100 is higher than the top of the water stirring tray 230, the stirring portion 231 rotates with the water stirring member 200 to stir the washing water above the water stirring tray 230, and can also rub the clothes above the water stirring tray 230, thereby enhancing the washing effect.

[0156] In this embodiment, a plurality of water stirring ribs 220 are also provided on the side wall of the support shaft. Specifically, the water stirring ribs 220 have a certain extension length along the axial direction of the washing tub 100, extending from the side wall of the first extension section 211 to the side wall of the second extension section 212. The plurality of water stirring ribs 220 are distributed at intervals along the circumference of the support shaft, and the interval angle between two adjacent water stirring ribs 220 enables the clothes to be washed in the interval area between the two adjacent water stirring ribs 220, and the clothes can contact the side wall of the first extension section 211 and move upward.

[0157] In this way, the area between two adjacent water-stirring ribs 220 of the side walls of the first extension section 211 and the second extension section 212 can contact the clothes without generating dead corners where dirt is easily accumulated.

[0158] Furthermore, in the present embodiment, the radial dimension of the water stirring rib 220 along the washing tub 100 increases first and then decreases from the lower end to the upper end.

[0159] As a specific embodiment, the cross-sectional shape of the water stirring rib 220 parallel to the radial direction of 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 outer periphery of the water stirring plate 230.

[0160] 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 in the area close to the axis can be enhanced, driving the clothes to move upward to the first guide surface 213, and finally forming a circular motion path.

[0161] It can be understood that the clothes moving along the bottom 100-3 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 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 100-3 of the barrel along the wall of the washing barrel 100.

[0162] More preferably, a smoothly transitioned rounded corner structure is provided at the connection position between the water stirring rib 220 and the support shaft, so that there are almost no cleaning dead corners on the water stirring component 200 where dirt is easily accumulated, thereby ensuring the cleanliness and hygiene of the inside of the washing barrel 100 to the greatest extent.

[0163] Further preferably, there is a rounded transition between the outer edge of the water-stirring rib 220 and the two side surfaces of the water-stirring rib 220 to avoid the existence of sharp corners that may scratch and damage clothes.

[0164] As a specific implementation, the thickness of the water-stirring rib 220 in the circumferential direction gradually decreases radially outward, and along the axial direction, the thickness of the middle area of ​​the water-stirring rib 220 is greater than the thickness at the upper and lower ends.

[0165] In this embodiment, the first guide surface 213 for guiding the clothes is formed by the change of the cross-sectional size of the support shaft itself in the water stirring member 200, so that the clothes are guided to form a circular path around the water stirring member 200 during the washing process, which improves the washing effect and prevents the clothes from being entangled. In addition, the structure in which the first guide surface 213 extends upward obliquely and finally completely covers the lower surface of the water stirring plate 230 is adopted. The position where the first guide surface 213 is connected to the first extension section 211 is more likely to contact the clothes during the washing process, thereby preventing the problem of a cleaning dead angle at this location.

[0166] It should be noted that, regardless of embodiment one or embodiment two, during washing, most of the clothes move upward along the outer edge of the water-stirring ribs 220 to the first guide surface 213, and a small number of clothes move upward within the area formed by two adjacent water-stirring ribs 220 and the support shaft to the first guide surface 213.

[0167] like Fig.18 As shown, in this embodiment, the water stirring member 200 includes a mounting portion 210-1 and a water stirring portion 240 extending upward from the mounting portion 210-1. The stirring shaft 300 rotatably passes through the mounting portion 100-2 of the barrel bottom 100-3 and is connected to the mounting portion 210-1.

[0168] As a specific embodiment, the distance from the side wall of the mounting portion 210- to the inner surface of the peripheral wall of the washing tub 100 is close to the distance from the side wall of the stirring shaft 300 to the inner surface of the peripheral wall of the washing tub 100. More specifically, the distance from the side wall of the mounting portion 210- to the inner surface of the peripheral wall of the washing tub 100 is slightly smaller than the distance from the side wall of the stirring shaft 300 to the inner surface of the peripheral wall of the washing tub 100.

[0169] In this way, the washing surface 100 - 3 of the barrel bottom 100 - 3 extending outward from the mounting portion 100 - 2 is completely exposed to the washing space above, thereby avoiding the problem of dirt and grime accumulating in the barrel bottom 100 - 2 .

[0170] In this embodiment, the dehydration shaft 110 connected to the washing barrel 100 is mounted on the stirring shaft 300. At the upper end of the dehydration shaft 110, a sealing structure 120 is arranged between the dehydration shaft 110 and the stirring shaft 300, so that the dehydration shaft 110 and the stirring shaft 300 can be sealed and connected relatively rotatably to prevent water from entering between the dehydration shaft 110 and the stirring shaft 300.

[0171] Specifically, the sealing structure 120 is sleeved on the stirring shaft 300 , and the outer peripheral wall of the sealing structure 120 is relatively fitted with the inner peripheral wall of the dehydration shaft 110 .

[0172] As a specific implementation, the upper end surface of the sealing structure 120 is flush or substantially flush with the inner surface of the barrel bottom 100 - 3 , thereby preventing a gap that is easy to harbor dirt and grime from being formed between the dehydration shaft 110 and the stirring shaft 300 .

[0173] The above-mentioned “substantially flush” means that the upper end surface of the sealing structure 120 may be slightly higher than the inner surface of the barrel bottom 100 - 3 , or slightly lower than the inner surface of the barrel bottom 100 - 3 .

[0174] For the structure where the upper end surface of the sealing structure 120 is slightly higher than the inner surface of the barrel bottom 100-3, no concave gap is formed between the dehydration shaft 110 and the stirring shaft 300. For the structure where the upper end surface of the sealing structure 120 is slightly lower than the inner surface of the barrel bottom 100-3, although a concave gap is formed, the concave size of the gap is very small, and the flushing force of the water flow passing through this place during washing is sufficient to remove the lint and dirt there, and no dirt will remain.

[0175] As a specific embodiment, the lower end surface of the water stirring member 200, that is, the lower end surface of the assembly portion 210-1, is at least partially arranged opposite to the upper end surface of the sealing structure 120. The assembly portion 210-1 is mounted on the upper end of the stirring shaft 300, and the lower end radius of the assembly portion 210-1 is greater than the radius of the stirring shaft 300.

[0176] Furthermore, a radius of a lower end of the fitting portion 210 - 1 is greater than an outer diameter of the sealing structure 120 .

[0177] In a specific embodiment, the difference between the radius of the lower end of the assembly portion 210 - 1 and the outer diameter of the sealing structure 120 is close to the wall thickness of the assembly portion 210 - 1 in the radial direction.
