DETAILED DESCRIPTION

[0041] 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.

[0042] In the description of the present invention, it should be noted that the terms "up", "down", "left", "right", "vertical", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0043] 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.

[0044] The pulsator structure 10 and the clothing processing device according to some embodiments of the present invention are described below with reference to the accompanying drawings.

[0045] like Figures 1 to 9 As shown, an embodiment of the first aspect of the present invention provides a pulsator structure 10, and the pulsator structure 10 is used in a clothing processing device, more specifically, the pulsator structure 10 is used in a washing machine. For example, the washing machine includes a washing drum for holding laundry, and the pulsator structure 10 is installed on the washing drum. A driving device (such as a motor) drives the pulsator structure 10 to rotate so that the pulsator structure 10 stirs the washing water and / or the laundry to achieve washing clothes; or, the washing drum and the pulsator structure 10 can also be set as an integrated structure. In detail, a plurality of protruding structures protruding toward the washing drum opening 210 are formed on the bottom wall of the washing drum, and the bottom wall of the washing drum and the plurality of protruding structures define the pulsator structure 10. The driving device drives the washing drum to rotate so that the pulsator structure 10 rotates synchronously to stir the washing water and / or the laundry to achieve washing clothes.

[0046] Of course, the impeller structure 10 is not limited to the above examples, and those skilled in the art can design the impeller structure 10 into other structural forms according to specific usage requirements.

[0047] like Figure 1 and Figure 2 As shown, the impeller structure 10 provided by the embodiment of the present invention includes an impeller 100 and an impeller plate 200 .

[0048] Specifically, Figure 1 and Figure 7 As shown, the impeller 100 has a stirring blade 110, and the impeller disk 200 is provided with an opening 210 adapted to the stirring blade 110. The impeller disk 200 can be movably inserted into the stirring blade 110 through the opening 210. For example, the impeller 100 is roughly disc-shaped, and a plurality of protruding blades 111 extending from the center along the radial direction of the impeller 100 are formed on the impeller 100. The plurality of blades 111 jointly define the stirring blade 110. The impeller disk 200 is provided with an opening 210 adapted to the plurality of blades 111, so that the impeller disk 200 can be sleeved on the stirring blade 110 and can move up and down relative to the stirring blade 110.

[0049] The impeller 200 of this embodiment can move up and down along the stirring blade 110, thereby changing the height of the stirring blade 110 relative to the washing water and the washings. If the impeller 200 moves to a position above and below the stirring blade 110, such as Figure 2 As shown, at this time, the stirring blade 110 is higher than the washing water and the laundry, so that the stirring blade 110 has a greater stirring force, can generate a stronger water flow, the washing water and the laundry are more fully stirred, the washing ratio is improved, and the washing effect is better, and the impeller 200 moves to the upper position of the stirring blade 110, as shown in FIG. Figure 1 As shown, at this time, the stirring blade 110 is at a lower height relative to the washing water and the laundry, so that the stirring blade 110 stirs more gently. On the one hand, it can achieve gentle washing of clothes such as silk and wool, avoid deformation and damage of silk, wool and other clothes, and enhance the protective effect of clothes. On the other hand, the driving force required by the low stirring blade 110 is smaller, which reduces product energy consumption and achieves energy saving and power saving.

[0050] In some embodiments, in order to increase the strength of the stirring blade 110, the blade 111 of the stirring blade 110 is set to be wide at the bottom and gradually narrowed upward, and the opening 210 of the impeller 200 is adapted to each blade 111. In this way, the impeller 200 can simultaneously change the height and width of the blade 111 when it moves up and down. In detail, if the impeller 200 moves to a lower position on the stirring blade 110, the blade 111 is relatively higher and wider, and the stirring force is further increased. If the impeller 200 moves to an upper position on the stirring blade 110, the blade 111 is relatively lower and narrower, the stirring force is further weakened, and the washing is gentler.

[0051] Furthermore, if Figure 7 As shown, the opening 210 of the impeller 200 is arranged to match the maximum width of the blade 111 to avoid the impeller 200 being stuck in the middle area of ​​the stirring blade 110, so that the impeller 200 can move up and down along the stirring blade 110 more freely and smoothly.

[0052] In some embodiments, Figure 3 As shown, the impeller 100 has a base 120 adapted to the inner barrel, the stirring blade 110 is arranged on the base 120, the impeller plate 200 is located above the base 120 and can move toward or away from the base 120, wherein the shape of the edge of the impeller plate 200 is adapted to the base 120 or the side wall 1121 of the inner barrel.

[0053] For example, the stirring blade 110 is detachably connected to the base 120. In more detail, the stirring blade 110 is connected to the base 120 by fasteners. During the assembly process, the impeller 200 is first put on the stirring blade 110, and then the stirring blade 110 and the impeller 200 are installed on the base 120 together, and the stirring blade 110 and the base 120 are locked with fasteners.

[0054] In some embodiments, the position of the impeller disk 200 relative to the stirring blade 110 can be manually set by the user according to usage requirements. For example, the impeller 100 is provided with a plurality of positions in sequence in the longitudinal direction. After the impeller disk 200 is inserted into the impeller 100, the user can push the impeller disk 200 so that the impeller disk 200 is located at any position, thereby realizing manual adjustment of the height of the stirring blade 110.

[0055] In other embodiments, the impeller structure 10 also includes an adjusting structure, which is used to apply force to the impeller disk 200. The impeller disk 200 moves up and down relative to the stirring blade 110 under the action of the adjusting structure. The adjusting structure is used to automatically adjust the position of the impeller disk 200 relative to the stirring blade 110, thereby avoiding the inconvenience of manual operation and improving the automation of the product.

[0056] Moreover, the impeller 200 can also realize reciprocating up and down motion along the stirring blade 110 under the action of the adjustment structure. Compared with the existing impeller 100 that can only generate circumferential rotational force by rotation, this embodiment increases the longitudinal force in the washing of clothes, helps to tumble the clothes, reduces the entanglement of clothes, and improves the cleaning ratio and washing uniformity.

[0057] In some embodiments, an adjustment structure is provided to actively adjust the movement of the impeller 200. For example, the adjustment structure is a motor, a hydraulic device, a bubble generating device, etc. The adjustment structure is controlled to apply a force to the impeller 200. Under the action of the force, the impeller 200 moves up and down along the stirring blade 110. In this way, the position of the impeller 200 relative to the stirring blade 110 is controllable, so that the impeller 200 can be adjusted accordingly according to the washing intensity requirement of each washing task, and the adjustment accuracy is high.

[0058] In some other embodiments, an adjustment structure may also be provided to passively adjust the movement of the impeller 200. For example, the adjustment structure is an elastic member (please refer to the elastic member). Figures 5 to 7 The spring 310 shown in FIG. Figure 8 and Fig. 9 The elastic air cushion 320 is shown in the figure, the elastic member is connected to the impeller 100, and the elastic member is deformed under the pressure of washing water and washings. The elastic deformation of the elastic member drives the impeller 200 to move up and down relative to the stirring blade 110, eliminating the driving member and making the product structure simpler.

[0059] In detail, the impeller 200 is set to be under pressure so that the elastic member is elastically compressed and drives the impeller 200 to move downward, and the elastic member recovers elastically to move the impeller 200 upward. It can be understood that the more laundry there is, the more water it inlets, so that the greater the gravity that the impeller 200 bears, and the greater the elastic deformation of the elastic member, the more the impeller 200 moves downward, and the higher the height of the stirring blade 110 relative to the washing water and the laundry, the stirring blade 110 has a greater stirring force and can generate a stronger water flow, so that the washing water and the laundry are more fully stirred, the washing ratio is improved, and the washing effect is better; and the less laundry there is, the less water it inlets, so that the gravity that the impeller 200 bears is reduced, and the elastic deformation of the elastic member is reduced, and the more the impeller 200 moves upward, the lower the height of the stirring blade 110 relative to the washing water and the laundry, the stirring blade 110 stirs more gently, reduces product energy consumption, and achieves energy saving and power saving.

[0060] Among them, Figure 8 and Fig. 9 As shown, the impeller 200 may not be connected to the elastic member, and the two only need to be able to contact each other. Alternatively, in order to reduce the risk of misalignment or loosening of the impeller 200, the impeller 200 may be connected to the elastic member.

[0061] In more detail, Figure 7 and Fig. 9 As shown, a plurality of elastic members are provided, and the plurality of elastic members are distributed at intervals along the circumference of the impeller 200. The plurality of elastic members increase the overall elasticity of the elastic members. Furthermore, the plurality of elastic members are evenly distributed.

[0062] Furthermore, a plurality of elastic members are located in a region of the impeller disk 200 close to the edge.

[0063] For example, the elastic member is any one or more of a spring 310 , an elastic air cushion 320 , an elastic rubber member, and an elastic silicone member.

[0064] In some embodiments, an elastic member is disposed below the impeller 200. For example, the impeller 200 has a first surface facing the upper end of the stirring blade 110 and a second surface facing away from the upper end of the stirring blade 110. The elastic member is disposed below the impeller 200 and is in contact with or connected to the second surface. The elastic member is designed to be hidden, so as to prevent the elastic member from directly contacting the laundry and avoiding the laundry from being entangled with the elastic member. This prevents the laundry from being scratched by the elastic member, thereby protecting the laundry and ensuring the reliability of the elastic deformation of the elastic member.

[0065] In some specific embodiments, the impeller 100 has a base 120 adapted to the inner barrel, the stirring blade 110 is disposed on the base 120 , and the impeller plate 200 is located above the base 120 , wherein the elastic member is located between the base 120 and the impeller plate 200 and connected to the base 120 .

[0066] In detail, Figure 8 and Fig. 9 As shown, the elastic member is an elastic air cushion 320, and a plurality of elastic air cushions 320 are fixed on the base 120. The impeller 200 is inserted into the stirring blade 110. When the stirring blade 110 and the impeller 200 are installed on the base 120 together, and the impeller 200 can contact the elastic air cushion 320, the impeller 200 moves downward under the pressure of washing water and laundry, and causes the elastic air cushion 320 to undergo elastic deformation. After washing is completed, the pressure on the impeller 200 is reduced, and the elastic air cushion 320 recovers elastically, causing the impeller 200 to move upward.

[0067] Furthermore, the base 120 is provided with a receiving groove 121, and the impeller 200 is provided with a plurality of guide columns 220. The base 120 is provided with receiving grooves 121 corresponding to the plurality of guide columns 220 one by one, and the impeller 200 is guided by the cooperation between the guide columns 220 and the receiving grooves 121.

[0068] In other specific embodiments, the impeller 100 has a base 120 adapted to the inner barrel, the stirring blade 110 is arranged on the base 120, and the impeller disc 200 is located above the base 120, wherein the base 120 is provided with a receiving groove 121, at least part of the elastic member extends into the receiving groove 121, and the elastic member is connected to the base 120. By installing the elastic member in the receiving groove 121, the impeller disc 200 can contact the upper surface of the base 120 after the elastic compression of the elastic member, and the impeller disc 200 has a larger activity space. When the impeller disc 200 contacts the base 120, the height of the stirring blade 110 relative to the washing water and the washings reaches the highest, and has a higher stirring force.

[0069] For example, Figure 5 , Figure 6 and Figure 7 As shown, the elastic member is a spring 310, a part of the spring 310 extends into the accommodating groove 121 and is connected to the base 120, and the other part extends out of the accommodating groove 121 and is connected to the impeller 200, the impeller 200 is inserted into the stirring blade 110, and then the stirring blade 110 and the impeller 200 are installed on the base 120 together, the impeller 200 moves downward under the pressure of washing water and washings, and the spring 310 is elastically compressed, and after washing is completed, the pressure on the impeller 200 is reduced, the spring 310 elastically recovers, and the impeller 200 moves upward.

[0070] Furthermore, there are multiple elastic members, and the base 120 is provided with accommodating grooves 121 corresponding to the multiple elastic members one by one.

[0071] An elastic member may also be arranged to extend into the receiving groove 121 and be connected to the base 120. A guide column 220 adapted to the receiving groove 121 may be provided on one side of the impeller 200 facing the base 120. The guide column 220 may be movably extended into the receiving groove 121 and guided by the receiving groove 121. The elastic member may be fixedly connected to the guide column 220. For example, the elastic member may be in a hollow ring shape, and part of the guide column 220 may extend into the elastic member and be connected to the elastic member. Alternatively, the elastic member may not be fixedly connected to the guide column 220. The receiving groove 121 has the functions of accommodating the elastic member and guiding and limiting. This increases the activity space of the impeller 200 while guiding and circumferentially limiting the up and down movement of the impeller 200, thereby ensuring the smoothness of the up and down movement of the impeller 200.

[0072] In detail, the elastic member is elastically compressed so that the guide post 220 extends into the receiving groove 121 and can move up and down in the receiving groove 121 , and the elastic member is elastically released so that at least part of the guide post 220 extends out of the receiving groove 121 .

[0073] Preferably, the elastic member is elastically released so that part of the guide post 220 extends out of the receiving slot 121 , and part of the guide post 220 remains in the receiving slot 121 , thereby preventing the guide post 220 from being separated from the receiving slot 121 .

[0074] Furthermore, a plurality of guide posts 220 are disposed on the impeller disk 200 , and a plurality of receiving grooves 121 corresponding to the plurality of guide posts 220 are disposed on the base 120 , wherein elastic members are disposed in at least some of the receiving grooves 121 .

[0075] In some specific embodiments, the accommodating groove 121 is a through groove that passes through the base 120 from top to bottom. In this way, the space between the impeller 200 and the base 120 is connected to the space between the inner and outer barrels through the through groove. The through groove is used to balance the internal and external pressures between the impeller 200 and the base 120, thereby ensuring the reliability and smoothness of the up and down movement of the impeller 200.

[0076] In some embodiments, the impeller 100 is provided with an axial limiting structure, and the impeller disc 200 is provided with an axial limiting matching structure. When the impeller disc 200 moves to the upper end area of ​​the stirring blade 110, the axial limiting structure is limited and matched with the axial limiting matching structure to prevent the impeller disc 200 from separating from the impeller 100. Among them, the upper end area of ​​the stirring blade 110 is not absolutely limited to the upper end surface of the stirring blade 110, and can also be a partial area below the upper end surface of the stirring blade 110. In this way, when the axial limiting structure and the axial limiting matching structure are limited and matched, a part of the stirring blade 110 is located above the impeller disc 200 to provide a certain stirring force.

[0077] In some specific embodiments, Figure 6 , Figure 7 and Fig. 9 As shown, a local area of ​​the stirring blade 110 is recessed from the outside to the inside to form a recessed portion 112, and the recessed portion 112 has a side wall 1121 and an upper wall 1122 connected to the side wall 1121. During assembly, the impeller 200 is inserted into the recessed portion 112 through the opening 210 from bottom to top and moves up and down along the side wall 1121, wherein the upper wall 1122 is formed as an axial limiting structure, and the opening 210 is formed as an axial limiting matching structure, which has a simple structure and reliable limiting.

[0078] Furthermore, an elastic member is provided on the impeller 100, and the elastic member is in contact with the impeller disc 200. When the elastic member is elastically compressed, the axial limiting structure and the axial limiting matching structure are separated. When the elastic member is elastically restored, the axial limiting structure and the axial limiting matching structure are limited and matched.
