Description

Technical Field

[0001] The invention belongs to the technical field of washing equipment, and specifically provides a washing machine and a pulsator structure thereof. Background Art

[0002] Current washing machines mainly include pulsator type washing machines and drum type washing machines.

[0003] The pulsator washing machine mainly includes a box body, an outer barrel, an inner barrel and a driving motor arranged in the box body. A pulsator is arranged at the bottom of the inner barrel. The driving motor is connected to the pulsator and can drive the pulsator to rotate. When the washing machine is running, the driving motor drives the pulsator to rotate forward and backward periodically, driving the clothes to move and achieve the purpose of washing.

[0004] The structure of the impeller is directly related to the cleaning efficiency of the washing machine. The existing impeller structure has a poor effect on moving clothes, resulting in a low cleaning efficiency of the washing machine.

[0005] Therefore, this field needs a new technical solution to solve the above problems. Summary of the invention

[0006] In order to solve the above-mentioned problems in the prior art, that is, to solve the problem that the existing pulsator structure has a poor effect of moving clothes, resulting in a low washing rate of the washing machine, the present invention provides a pulsator structure of a washing machine, the pulsator structure comprising: a pulsator plate, having a first annular area and a second annular area, the first annular area being located radially inward of the second annular area; a first water deflector component located in the first annular area, the first water deflector component comprising at least one first water deflector blade; a second water deflector component located in the second annular area, the second water deflector component comprising at least one second water deflector blade; wherein the guiding directions of the first water deflector component and the second water deflector component are opposite.

[0007] In a preferred technical solution of the above-mentioned impeller structure, the radial width of the first annular region is greater than the radial width of the second annular region.

[0008] In a preferred technical solution of the above-mentioned impeller structure, the radial width of the first annular region is twice the radial width of the second annular region.

[0009] In a preferred technical solution of the above impeller structure, the first water-repelling blade includes a first base, the second water-repelling blade includes a second base, and both the first base and the second base are arc-shaped convex structures.

[0010] In a preferred technical solution of the above-mentioned impeller structure, the first base body rises in a clockwise direction or a counterclockwise direction, and the second base body rises in a direction opposite to the rising direction of the first base body.

[0011] In a preferred technical solution of the above-mentioned impeller structure, the first base is widened along its ascending direction, and / or the second base is widened along its ascending direction.

[0012] In the preferred technical solution of the above-mentioned impeller structure, a plurality of arc-shaped ribs are arranged on the upper surface of the first substrate.

[0013] On the other hand, the present invention further provides a washing machine, comprising the above-mentioned pulsator structure.

[0014] In the preferred technical solution of the above-mentioned washing machine, it includes: a box body; an outer barrel, which is arranged in the box body; an inner barrel, which is arranged in the outer barrel, and the impeller structure is arranged in the inner barrel; a motor, which is located below the inner barrel, and the output shaft of the motor is connected to the impeller structure; wherein the outer barrel includes a water holding part and a supporting part, the water holding part is fixedly connected to the bottom plate of the box body through the supporting part, the water holding part is sealingly connected to the outer shell of the motor, and the inner barrel is freely accommodated in the accommodation space formed by the water holding part.

[0015] In a preferred technical solution of the above washing machine, the water holding part includes a water tub and a flexible connector, and the water tub is sealedly connected to the housing via the flexible connector.

[0016] Those skilled in the art can understand that, in the preferred technical solution of the present invention, the impeller structure includes a first water-deflecting component, a second water-deflecting component and a wave plate, the wave plate includes a first annular area and a second annular area, the first annular area is located radially inward of the second annular area, the first water-deflecting component is located in the first annular area, the second water-deflecting component is located in the second annular area, the first water-deflecting component includes at least one first water-deflecting blade, the second water-deflecting component includes at least one second water-deflecting blade, and the guiding directions of the first water-deflecting component and the second water-deflecting component are opposite. By arranging two groups of water-deflecting components on the wave plate and making the guiding directions of the two groups of water-deflecting components opposite, the impeller structure can move the clothes regardless of whether it rotates forward or backward, so that the clothes can be better agitated, and the washing rate of the washing machine can be improved.

[0017] Furthermore, the radial width of the first annular area is greater than the radial width of the second annular area. Through such an arrangement, the size of the first annular area along the radial direction of the wave disc is greater than the size of the second annular area along the radial direction of the wave disc. In this case, the size of the first water-repelling blade along the radial direction of the wave disc can be greater than the size of the second water-repelling blade along the radial direction of the wave disc. In this way, the moving ability of the first water-repelling blade is greater than the moving ability of the second water-repelling blade. In other words, the first water-repelling blade plays a major role, and the second water-repelling blade plays an auxiliary role. During the operation of the washing machine, under the action of the second water-repelling blade, the clothes can be prevented from sticking to the inner wall of the inner barrel. On this basis, the clothes can be kept as far away from the center of the wave disc as possible, thereby achieving a better washing effect.

[0018] Furthermore, the radial width of the first annular region is twice the radial width of the second annular region. By such an arrangement, the washing machine has the highest cleaning efficiency.

[0019] Furthermore, the first arc-shaped protrusion structure is widened along its rising direction. This arrangement is more conducive to stirring the clothes, thereby improving the washing efficiency of the washing machine.

[0020] Furthermore, a plurality of arc-shaped convex ribs are provided on the first arc-shaped convex structure, and the arc-shaped convex ribs can increase the friction with the clothes, thereby improving the washing rate of the washing machine.

[0021] Furthermore, the second arc-shaped protrusion structure is widened along its rising direction. This arrangement is more conducive to stirring the clothes, thereby improving the washing efficiency of the washing machine.

[0022] In addition, the present invention further provides a washing machine based on the above technical solution. Since the washing machine adopts the above impeller structure, it has the technical effects of the above impeller structure. Compared with the washing machine in the prior art, the washing machine of the present invention has a better cleaning rate.

[0023] Furthermore, the outer barrel of the washing machine includes a water holding part and a supporting part, and the water holding part is fixedly connected to the bottom plate of the casing through the supporting part. Through such an arrangement, the volume of the casing can be reduced, thereby reducing the occupied space of the washing machine; specifically, the outer barrels of existing washing machines with a pulsator structure are connected to the casing through a plurality of vibration-damping suspension rods, generally 4 vibration-damping suspension rods, which are evenly arranged along the circumference of the outer barrel, the top ends of the vibration-damping suspension rods are connected to the casing, and the bottom ends of the vibration-damping suspension rods are connected to the outer barrel. However, the outer barrel of the washing machine of the present invention is directly fixedly connected to the casing, eliminating the vibration-damping suspension rods, reducing the occupied space, thereby reducing the volume of the casing, and, in the operation of the existing washing machines with a pulsator structure, in order to prevent the outer barrel from colliding with the casing, it is necessary to have a sufficient safety gap between the outer barrel and the casing. However, the outer barrel of the washing machine of the present invention is fixedly connected to the casing. During the operation of the washing machine, the outer barrel will not move relative to the casing, so there is no need to worry about the outer barrel colliding with the casing. Therefore, the gap between the outer barrel and the casing can be made as small as possible, thereby further reducing the volume of the casing.

[0024] Furthermore, the water holding part includes a water holding tub and a flexible connector, and the water holding tub is sealed and connected to the housing of the motor through the flexible connector. Through such an arrangement, it is possible to prevent water in the water holding tub from leaking and allow the housing to move relative to the water holding tub. BRIEF DESCRIPTION OF THE DRAWINGS

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] First refer to Figure 1 and Figure 2 ,in, Figure 1 is a schematic structural diagram of a washing machine of the present invention; Figure 2 It is a partial cross-sectional view of the washing machine of the present invention.

[0040] like Figure 1 and Figure 2 As shown, the washing machine of the present invention mainly includes a housing 1 and an outer tub 2, an inner tub 3 and a motor 4 arranged in the housing 1.

[0041] Among them, the outer barrel 2 includes a water holding part and a supporting part. The water holding part is fixedly connected to the bottom plate 11 of the box body 1 through the supporting part, and the water holding part is also sealedly connected to the outer shell 41 of the motor 4; the inner barrel 3 is freely accommodated in the accommodating space formed by the water holding part, the motor 4 is installed under the inner barrel 3, and the output shaft of the motor 4 is fixedly connected to the inner barrel 3.

[0042] It should be noted that, by fixedly connecting the outer tub 2 to the housing 1 , the volume of the housing 1 can be reduced, thereby reducing the space occupied by the washing machine.

[0043] Specifically, the outer drum of an existing pulsator washing machine is generally mounted on the casing via a plurality of vibration-damping hangers, which occupy a large space. However, the washing machine of the present invention directly fixes the outer drum 2 to the casing 1, eliminating the vibration-damping hangers and reducing the occupied space, thereby reducing the volume of the casing 1 and further reducing the occupied space of the washing machine.

[0044] Continue reading Figure 1 and Figure 2 , the water holding part includes a water tub 21 and a flexible connector 22, the inner barrel 3 is arranged in the water tub 21, the water tub 21 is sealedly connected to the outer shell 41 of the motor 4 through the flexible connector 22, and the water tub 21 is fixedly connected to the bottom plate 11 of the box body 1 through the supporting part. In other words, the bottom of the water tub 21 is the outer shell 41 of the motor 4, the bottom end of the water tub 21 is sealedly connected to the outer shell 41 through the flexible connector 22, and the water tub 21, the flexible connector 22 and the outer shell 41 together form a water holding space. Among them, the flexible connector 22 is made of a flexible waterproof material, such as rubber.

[0045] Continue reading Figure 1 and Figure 2 The supporting part includes a plurality of supporting frames 23, which are distributed along the circumference of the water tub 21, the top of the supporting frame 23 is connected to the outer wall of the water tub 21, and the bottom of the supporting frame 23 is fixedly connected to the bottom plate 11 of the box body 1. The supporting frame 23 and the water tub 21 can be fixedly connected or set as one body.

[0046] Continue reading Figure 1 In a possible case, the number of the support frames 23 is four, and the four support frames 23 are evenly distributed along the circumference of the water tub 21 .

[0047] Continue reading Figure 2 , and then see Figure 3 ,in, Figure 3 yes Figure 2 A partial enlarged view of the .

[0048] like Figure 2 and Figure 3As shown, a first connecting groove 211 is formed on the outer wall of the water tub 21, and a first U-shaped connecting structure 221 is formed at the top end of the flexible connecting member 22. The first connecting groove 211 is adapted to the first U-shaped connecting structure 221, and the top end of the flexible connecting member 22 is sealedly connected to the water tub 21 via the first connecting groove 211 and the first U-shaped connecting structure 221.

[0049] When installed, the first U-shaped connection structure 221 can be tightly fixed in the first connection groove 211 by a clamping piece, so that the first U-shaped connection structure 221 can be tightly fitted on the inner wall of the first connection groove 211. Figure 3 As shown, the first U-shaped connection structure 221 and the first connection groove 211 can be tightly fixed by the clamp 5 .

[0050] By configuring the top end of the flexible connector 22 to be a U-shaped connection structure, it is possible to effectively prevent it from falling out of the first connection groove 211 , thereby improving the connection stability and sealing reliability between the flexible connector 22 and the water tub 21 .

[0051] Continue reading Figure 2 and Figure 3 A second connecting groove 411 is formed on the housing 41 of the motor 4, and a second U-shaped connecting structure 222 is formed at the bottom end of the flexible connecting member 22. The second connecting groove 411 is adapted to the second U-shaped connecting structure 222, and the bottom end of the flexible connecting member 22 and the housing 41 are sealed and connected via the second U-shaped connecting structure 222 and the second connecting groove 411.

[0052] When installed, the second U-shaped connection structure 222 can be tightly fixed in the second connection groove 411 by a clamping piece, so that the second U-shaped connection structure 222 can be tightly fitted on the inner wall of the second connection groove 411. Figure 3 As shown, the second U-shaped connection structure 222 and the second connection groove 411 can be tightly fixed by the clamp 5.

[0053] By configuring the bottom end of the flexible connector 22 to be a U-shaped connection structure, it is possible to effectively prevent it from falling out of the second connection groove 411 , thereby improving the connection stability and sealing reliability between the flexible connector 22 and the housing 41 .

[0054] Continue reading Figure 2 , and then see Figure 4 ,in, Figure 4 It is a top view of the inner barrel of the washing machine of the present invention.

[0055] like Figure 2 and Figure 4As shown, a pulsator structure is provided in the inner barrel 3 , and the pulsator structure is fixedly connected to the output shaft of the motor 4 . The pulsator structure includes a first water-deflecting component, a second water-deflecting component and a pulsator disc 33 .

[0056] Among them, the wave plate 33 includes a first annular area 331 and a second annular area 332, the first annular area 331 is located radially inside the second annular area 332, the first water deflector component is located in the first annular area 331, the second water deflector component is located in the second annular area 332, the first water deflector component includes at least one first water deflector blade 31, the second water deflector component includes at least one second water deflector blade 32, and the guiding directions of the first water deflector component and the second water deflector component are opposite.

[0057] By arranging two groups of water-repelling components on the wave disc 33 and making the guiding directions of the two groups of water-repelling components opposite, the impeller structure can move the clothes regardless of whether it rotates forward or backward, thereby better stirring the clothes and further improving the washing rate of the washing machine.

[0058] Continue reading Figure 4 , the radial width d1 of the first annular region 331 is greater than the radial width d2 of the second annular region 332 .

[0059] Through such an arrangement, the size of the first annular area 331 along the radial direction of the wave disc 33 is larger than the size of the second annular area 332 along the radial direction of the wave disc 33. In this case, the size of the first water-repelling blade 31 along the radial direction of the wave disc 33 can be larger than the size of the second water-repelling blade 32 along the radial direction of the wave disc 33. In this way, the shifting ability of the first water-repelling blade 31 is greater than the shifting ability of the second water-repelling blade 32. In other words, the first water-repelling blade 31 plays a major role, and the second water-repelling blade 32 plays an auxiliary role. During the operation of the washing machine, under the action of the second water-repelling blade 32, the clothes can be prevented from sticking to the inner wall of the inner barrel 3. On this basis, the clothes can be kept as far away from the center of the wave disc 33 as possible, thereby achieving a better washing effect.

[0060] Furthermore, the inventors have repeatedly tested and verified that the washing machine has the highest cleaning efficiency when the radial width d1 of the first annular region 331 is twice the radial width d2 of the second annular region 332. That is, when d1=2×d2, the washing machine has the highest cleaning efficiency.

[0061] Continue reading Figure 4 The first water-repelling blade 31 includes a first base, and the second water-repelling blade 32 includes a second base. Both the first base and the second base are arc-shaped convex structures.

[0062] Among them, the first substrate rises in a counterclockwise direction, that is, the vertical height of the starting end A1 of the first substrate is smaller than the vertical height of the terminal end A2 of the first substrate, and the second substrate rises in a clockwise direction, that is, the vertical height of the starting end B1 of the second substrate is smaller than the vertical height of the terminal end B2 of the second substrate. In other words, the rising directions of the first substrate and the second substrate are exactly opposite.

[0063] It should be noted that the first base may also be raised in a clockwise direction, and correspondingly, the second base may be raised in a counterclockwise direction.

[0064] Continue reading Figure 4 The first substrate is widened along its rising direction, that is, the horizontal width of the starting end A1 of the first substrate is smaller than the horizontal width of the terminal end A2 of the first substrate. This arrangement is more conducive to stirring the clothes, thereby improving the washing rate of the washing machine.

[0065] Continue reading Figure 4 A plurality of arc-shaped convex ribs 34 are provided on the first substrate, and the arc-shaped convex ribs 34 can increase the friction with the clothes, thereby improving the washing rate of the washing machine.

[0066] Continue reading Figure 4 The second base is widened along its rising direction, that is, the horizontal width of the starting end B1 of the second base is smaller than the horizontal width of the terminal end B2 of the second base. This arrangement is more conducive to stirring the clothes, thereby improving the washing rate of the washing machine.

[0067] Continue reading Figure 4 Three first water-repelling blades 31 are arranged in the first annular area 331 , and six second water-repelling blades 32 are arranged in the second annular area 332 .

[0068] It should be noted that the number of the first water-repelling blades 31 is not limited to three. For example, the number of the first water-repelling blades 31 can also be two or four. Similarly, the number of the second water-repelling blades 32 is not limited to six. For example, the number of the second water-repelling blades 32 can also be five or seven. Such adjustments and changes to the specific numbers of the first water-repelling blades 31 and the second water-repelling blades 32 do not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention.

[0069] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
