Description

Technical Field

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

[0002] Washing equipment such as washing machines, shoe washers, etc. can greatly reduce the time users spend on doing housework, provide convenience for users' lives, and have become essential electrical appliances in modern life.

[0003] However, in common pulsator washing machines, the pulsator is an integral structure. During the washing process, the pulsator can only exert a force in a single direction on the laundry through its upper end surface. The laundry will rotate along with the pulsator in the water flow, resulting in a decrease in the relative movement speed between the laundry and the upper end surface of the pulsator, reducing the contact and friction between the laundry and the pulsator, thereby reducing the washing efficiency of the washing machine.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The object of the present invention is to provide a washing device, by arranging a pulsator assembly into first and second wheels that can directly contact the laundry and rotate them respectively, so that the pulsator can generate positive and negative torques on the laundry at the same time, avoiding the laundry and the pulsator from rotating at the same speed, so as to achieve the purpose of increasing the relative movement rate between the pulsator and the laundry and enhancing the washing efficiency of the washing device.

[0006] Another object of the present invention is to provide a control method applied to the above-mentioned washing equipment to achieve the purpose of controlling the first and second wheels to rotate in the same direction or in opposite directions according to the action requirements of the washing equipment, thereby ensuring that the various components in the washing equipment cooperate with each other and operate smoothly.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] A washing device comprises a reducer and a pulsator assembly, wherein the pulsator assembly comprises a first wheel disc and a second wheel disc located above the first wheel disc; the first and second wheel discs are respectively sleeved on the output part of the reducer, and the output part can drive the first and second wheel discs to rotate respectively.

[0009] Furthermore, the first wheel disc includes a washing part and a connecting part, the washing part is annular and sleeved on the outer circumference of the connecting part, the connecting part is lower than the upper end surface of the washing part to form a groove on the first wheel disc, and the second wheel disc is concentrically embedded in the groove.

[0010] Furthermore, a main brush is provided on the upper end surface of the washing part, and the main brush extends from its root to the top along the axial direction of the washing part, and the top of the main brush is higher than the upper end surface of the second wheel disc.

[0011] Furthermore, the second wheel disc is provided with auxiliary brushes, which are evenly distributed at the center of the upper end surface of the second wheel disc and form an annular interval with the main brush on the upper end surface of the second wheel disc.

[0012] Furthermore, the output part includes a central rotating shaft and a first flange shaft concentrically sleeved on the outside of the central rotating shaft. The central rotating shaft and the first flange shaft can rotate in the same direction or in opposite directions. The central rotating shaft passes through the first wheel disc and is fixedly connected to the second wheel disc. The first flange shaft is fixedly connected to the first wheel disc.

[0013] Furthermore, it also includes a barrel body, the impeller assembly is located in the cavity of the barrel body, the reducer is installed below the barrel body, and the output part passes through the bottom wall of the barrel body and is respectively connected to the barrel body and the impeller assembly.

[0014] Furthermore, the output part comprises a second flange shaft coaxially sleeved on the outside of the first flange shaft, and the central rotating shaft, the first flange shaft and the second flange shaft can rotate in the same direction or in opposite directions;

[0015] The central rotating shaft passes through the bottom wall of the barrel body and the first wheel disc and is fixedly connected to the second wheel disc. The first flange shaft passes through the bottom wall of the barrel body and is fixedly connected to the first wheel disc. The second flange shaft is fixedly connected to the bottom wall of the barrel body.

[0016] Furthermore, a brush seat protruding from the end surface of the second wheel disc is provided at the center thereof, the upper end surface of the brush seat is hemispherical, and the auxiliary brushes are evenly distributed on the upper end surface of the brush seat.

[0017] The present invention also provides a control method applied to the above-mentioned washing device, which controls the first wheel disc and the second wheel disc to rotate in opposite directions during the washing stage and / or the drainage stage;

[0018] The first wheel disc and the second wheel disc are controlled to rotate in the same direction and at the same speed during the dehydration stage.

[0019] Furthermore, during the washing stage, the first wheel disc and the second wheel disc are controlled to change their rotation directions once at a certain interval.

[0020] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0021] 1. By arranging the pulsator assembly with the first wheel disc and the second wheel disc which can rotate separately, the end surface of the pulsator assembly which contacts and rubs with the laundry to be washed is divided into two parts, so that the first wheel disc and the second wheel disc can be used to apply force to the laundry respectively, and the first wheel disc and the second wheel disc are connected to the output part of the reducer separately, the first wheel disc and the second wheel disc can rotate in the same direction or in the opposite direction, and the opposite rotation of the first wheel disc and the second wheel disc can generate clockwise and counterclockwise torque on the laundry at the same time, which can avoid the problem that the laundry is driven by the pulsator assembly and gradually rotates at the same speed, thereby enhancing the relative friction and contact effect between the pulsator assembly and the laundry, and improving the washing efficiency of the laundry.

[0022] 2. The first wheel is set as a connecting part and a washing part. The connecting part is located in the center and forms two high and low end faces relative to the washing part, so that a sink capable of accommodating the second wheel is formed in the center of the first wheel. In this way, the gap between the second wheel and the first wheel is eliminated, avoiding the problem that clothes are stuffed between the first and second wheels, causing malfunction or even damage to the washing equipment.

[0023] 3. During the rotation of the washing part, the bristles of the main brush are constantly bent and straightened due to the contact with the clothes, which is helpful to loosen and remove the stubborn stains attached to the clothes, and improve the cleanliness of the impeller assembly for washing clothes.

[0024] 4. By respectively arranging the main brush and the auxiliary brush on the first wheel and the second wheel, and with a gap between the main brush and the auxiliary brush, the clothes can come into contact with the main brush and the auxiliary brush from multiple angles. At the same time, the clothes constantly adjust their posture as the first wheel and the second wheel rotate, which greatly increases the proportion of the area of ​​the impeller assembly that scrubs the clothes to the overall area of ​​the clothes.

DETAILED DESCRIPTION

[0031] 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.

[0032] In the description of the present invention, it should be noted that the terms "inside", "outside", etc. indicate orientations or positional relationships based on the orientations 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 orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "contacted", 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 directly connected or indirectly connected 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.

[0034] In the present invention, "washing equipment" refers to a general term for a type of household appliances that can perform washing, dehydration, drying and other programs, such as washing machines, shoe washing machines, etc.

[0035] like Figure 1 and Figure 2 As shown, in an embodiment of the present invention, a washing device capable of increasing the friction between clothes and a pulsator is introduced.

[0036] The washing device comprises a reducer 200 and a pulsator assembly 300. The pulsator assembly 300 is a rotating body structure, and its end surface is circular. The pulsator assembly 300 is sleeved on the output part 210 of the reducer 200, and is arranged to coincide with the central axis of the output part 210.

[0037] Specifically, the impeller assembly 300 includes a first wheel disc 320 and a second wheel disc 310 located above the first wheel disc 320. The first wheel disc 320 and the second wheel disc 310 are both configured as circular flat plates. The outer diameter of the first wheel disc 320 is greater than the outer diameter of the second wheel disc 310.

[0038] In the axial direction of the impeller assembly 300, the lower end surface of the first wheel 320 constitutes the lower end surface of the impeller assembly 300, and the annular portion of the second wheel 310 extending from the upper end surface of the first wheel 320 and the upper end surface of the second wheel 310 together constitute the upper end surface of the impeller assembly 300.

[0039] Thus, the upper end surface of the pulsator assembly 300 has a circular area at the center and an annular area at the periphery. During the washing process, the pulsator assembly 300 rubs and touches the laundry through the circular area and the annular area to achieve the effect of washing the laundry.

[0040] In addition, the reducer 200 includes an output part 210 having at least two rotating shafts. The two rotating shafts are arranged with overlapping central axes and can rotate in the same direction or in the opposite direction. The first wheel disc 320 and the second wheel disc 310 are respectively sleeved on the output part 210 and are respectively connected to the two rotating shafts in a one-to-one correspondence. Under the drive of the motor, the reducer 200 can rotate in different directions and / or at different speeds through the transmission and distribution of the internal transmission gears, thereby driving the first wheel disc 320 and the second wheel disc 310 to rotate respectively.

[0041] Preferably, the impeller assembly 300 includes a plurality of wheels with different diameters. These wheels are stacked from top to bottom in the order of diameter from small to large. Moreover, the diameters of any two adjacent wheels have a difference of more than 5 cm. In this way, the end surface of the impeller assembly 300 facing upward can form a plurality of annular areas, and the adjacent wheels are driven to rotate in the opposite direction by the reducer 200, so as to form a local scrubbing effect on the clothes.

[0042] In this embodiment, by setting the agitator assembly 300 as a first disk 320 and a second disk 310 that can rotate independently, the end faces of the agitator assembly 300 that contact and rub against the laundry are separated into two parts, so that forces can be applied to the laundry by the first disk 320 and the second disk 310 respectively. Moreover, the first disk 320 and the second disk 310 are separately connected to the output part 210 of the speed reducer 200. The first disk 320 and the second disk 310 can rotate in the same direction or in opposite directions. When the first disk 320 and the second disk 310 rotate in opposite directions, torques in both the clockwise and counterclockwise directions can be generated on the laundry simultaneously, which can avoid the problem that the laundry is driven by the agitator assembly 300 and gradually rotates at the same speed, enhancing the relative friction and contact effect between the agitator assembly 300 and the laundry and improving the washing efficiency of the laundry.

[0043] As Figure 1 and Figure 2 shown, in another embodiment of the present invention, an agitator assembly 300 that can prevent the laundry from being caught between the first disk 320 and the second disk 310 is introduced.

[0044] Since the first disk 320 and the second disk 310 are arranged vertically, there is a relatively large gap between their end faces. When the first disk 320 and the second disk 310 rotate, the laundry is often brought into the gap and wound around the rotating shaft of the output part 210, resulting in the stop of the rotation of the agitator assembly 300.

[0045] To eliminate the gap between the first disk 320 and the second disk 310, the second disk 310 can be embedded in the center of the first disk 320. It is provided that the first disk 320 includes an annular washing part 321 and a connecting part 322 located in the annular hole of the washing part 321.

[0046] Specifically, the washing part 321 is annular, and an annular hole penetrating the washing part 321 is provided in its center.

[0047] The connecting part 322 includes several brackets 323 and a center flange 324. A through hole for connecting the connecting part 322 is provided in the center of the center flange 324. The outer periphery of the center flange 324 is connected to the brackets 323.

[0048] In the connecting part 322, at least two brackets 323 are symmetrically distributed on the outer periphery of the center flange 324. And the connecting part 322 is connected to the side wall of the annular hole by the brackets 323.

[0049] In addition, the upper end surface of the connection portion 322 is recessed in the annular hole. Furthermore, the lower end surface of the connection portion 322 is flush with the lower end surface of the washing portion 321, thereby forming a sink groove on the upper end surface of the first wheel disc 320. When the second wheel disc 310 is concentrically sleeved in the annular hole, the lower end of the second wheel disc 310 is at least embedded in the sink groove and can rotate freely relative to the first wheel disc 320.

[0050] In this embodiment, the first wheel 320 is configured as a connecting portion 322 and a washing portion 321. The connecting portion 322 is located at the center and forms two high and low end surfaces relative to the washing portion 321, so that a sink capable of accommodating the second wheel 310 is formed in the center of the first wheel 320. This eliminates the gap between the second wheel 310 and the first wheel 320, thereby preventing clothes from being stuffed between the first wheel 320 and the second wheel 310, causing the washing device to malfunction or even be damaged.

[0051] like Figure 1 and Figure 2 As shown, in another embodiment of the present invention, a pulsator assembly 300 capable of better processing clothes is introduced.

[0052] In order to enhance the contact and washing effect of the pulsator assembly 300 on the clothes, the upper end surface of the washing part 321 is provided with a main brush 325 evenly distributed on the entire end surface.

[0053] The bristles of the main brush 325 extend upward along the central axis of the washing portion 321 until they are flush with the upper end surface of the second wheel disc 310. Preferably, the top surface of the main brush 325 is higher than the end surface of the second wheel disc 310, so that the main brush 325 touches the clothes when washing them, thereby increasing the interaction force between the main brush 325 and the clothes.

[0054] In this embodiment, the bristles of the main brush 325 are constantly bent and straightened due to the contact with the clothes during the rotation of the washing part 321, which is conducive to loosening and removing stubborn stains attached to the clothes, thereby improving the cleanliness of the impeller assembly 300 for washing clothes.

[0055] like Figure 1 and Figure 2 As shown, in another embodiment of the present invention, a pulsator assembly 300 is introduced that can scrub clothes from multiple angles.

[0056] In order to better drive the clothes to move relative to the pulsator and adjust the contact position and angle between the clothes and the pulsator, an auxiliary brush 311 is provided at the center of the end surface of the second wheel disc 310. The auxiliary brush 311 can be provided in a strip shape extending along the diameter of the second wheel disc 310, or in a circular shape.

[0057] Preferably, the auxiliary brush 311 is distributed in a circular shape at the center of the upper end surface of the second wheel disc 310. Moreover, the diameter of the auxiliary brush 311 is smaller than the diameter of the end surface of the second wheel disc 310. The outer periphery of the auxiliary brush 311 and the inner periphery of the main brush 325 form an annular interval at the upper end surface of the second wheel disc 310.

[0058] In this embodiment, by correspondingly arranging the main brush 325 and the auxiliary brush 311 on the first wheel 320 and the second wheel 310 respectively, and a gap is provided between the main brush 325 and the auxiliary brush 311, the clothes are brought into contact with the main brush 325 and the auxiliary brush 311 from multiple angles, and the clothes continuously adjust their postures with the rotation of the first wheel 320 and the second wheel 310, which greatly increases the ratio of the area of ​​the impeller assembly 300 for scrubbing the clothes to the overall area of ​​the clothes.

[0059] like Figure 1 and Figure 2 As shown, in another embodiment of the present invention, an output portion 210 is introduced that can better drive each wheel in the impeller assembly 300 to rotate independently.

[0060] In order to conveniently control the rotation direction and rotation speed ratio of each wheel in the impeller assembly 300 and simplify the structure of the impeller assembly 300, the output part 210 of the reducer 200 is set as a multi-shaft sleeve structure. Each shaft is provided with a corresponding gear in the reducer 200. Through the meshing and mutual transmission of multiple gears, each shaft is driven to rotate, and the speed and rotation direction of the shaft are distributed.

[0061] Specifically, the output part 210 includes a central rotating shaft 211 and a first flange shaft 212. The central rotating shaft 211 is set as a solid shaft, and the first flange shaft 212 is set as a hollow shaft. The central rotating shaft 211 is concentrically sleeved in the first flange shaft 212. In addition, a sliding bearing or a rolling bearing is provided between the outer circumference of the central rotating shaft 211 and the hollow inner circumference of the first flange shaft 212.

[0062] In addition, the central rotating shaft 211 and the first flange shaft 212 can rotate in the same direction or in the opposite direction under the drive of the reducer 200. The first flange shaft 212 and the first wheel disc 320 are arranged to coincide with the central axis, and the central flange 324 of the connecting portion 322 is fixedly connected to the end surface of the first flange shaft 212. The central rotating shaft 211 passes through the through hole of the connecting portion 322 and is fixedly connected to the second wheel disc 310.

[0063] In this embodiment, the output part 210 is configured as two rotating shaft structures that are socketed together and rotate independently, so that the wheels in the impeller assembly 300 are correspondingly connected to each rotating shaft, which can conveniently control the rotation direction and rotation speed ratio of each wheel, thereby optimizing the overall structure and washing function of the washing equipment.

[0064] like Figure 1 and Figure 2 As shown, in another embodiment of the present invention, a washing device is introduced which can drive the barrel body 100 and the impeller assembly 300 to rotate and control the barrel body 100 and the impeller assembly 300 to rotate smoothly and coordinately with the washing function.

[0065] The washing device includes a barrel 100. The pulsator assembly 300 is located in the cavity of the barrel 100, and the reducer 200 is installed below the barrel 100. The output part 210 passes through the bottom wall of the barrel 100 and is connected to the barrel 100 and the pulsator assembly 300 respectively.

[0066] The output part 210 includes a central rotating shaft 211, a first flange shaft 212 concentrically sleeved on the outside of the central rotating shaft 211, and a second flange shaft 213 concentrically sleeved on the outside of the first flange shaft 212. The central rotating shaft 211 is fixedly connected to the second wheel disc 310, the first flange shaft 212 is fixedly connected to the first wheel disc 320, and the second flange shaft 213 is fixedly connected to the bottom wall of the barrel body 100.

[0067] The central rotating shaft 211 , the first flange shaft 212 , and the second flange shaft 213 can rotate in the same direction or in opposite directions.

[0068] Specifically, the central shaft 211 passes through the bottom wall of the barrel body 100 and the first wheel disc 320 and is fixedly connected to the second wheel disc 310. The first flange shaft 212 passes through the bottom wall of the barrel body 100 and is fixedly connected to the first wheel disc 320. The second flange shaft 213 is fixedly connected to the bottom wall of the barrel body 100.

[0069] Further, the barrel body 100 includes an inner barrel 120 and an outer barrel 110. The inner barrel 120 is sleeved in the cavity of the outer barrel 110, and the central axis of the inner barrel 120 and the outer barrel 110 are arranged to coincide. The reducer 200 is installed below the outer barrel 110. The impeller assembly 300 is installed in the cavity of the inner barrel 120.

[0070] Specifically, the central shaft 211 passes through the bottom wall of the inner barrel 120, the bottom wall of the outer barrel 110 and the first wheel disc 320, and is fixedly connected to the second wheel disc 310. The first flange shaft 212 passes through the bottom wall of the inner barrel 120 and the bottom wall of the outer barrel 110, and is fixedly connected to the first wheel disc 320. The second flange shaft 213 passes through the bottom wall of the outer barrel 110, and is fixedly connected to the bottom wall of the inner barrel 120.

[0071] In this embodiment, the output part 210 is configured as three rotating shaft structures that are socketed together and rotate independently, so that the wheels in the inner barrel 120 and the impeller assembly 300 are correspondingly connected to each rotating shaft, which can conveniently control the driving of the inner barrel 120 and the impeller assembly 300 to rotate, thereby controlling the coordinated rotation of the inner barrel 120 and the impeller assembly 300 to achieve the effect of improving the smoothness and coordination of the washing equipment.

[0072] like Figure 1 and Figure 2 As shown, in another embodiment of the present invention, a pulsator assembly 300 is introduced that can scrub clothes from multiple angles.

[0073] In order to better drive the clothes to move relative to the pulsator and adjust the contact position and angle between the clothes and the pulsator, a brush seat 312 protruding from the end surface of the second wheel disc 310 is provided at the center of the second wheel disc 310.

[0074] In addition, the upper end surface of the brush holder 312 is hemispherical. The auxiliary brushes 311 are evenly distributed on the upper end surface of the brush holder 312 , and the outer peripheral surface of the auxiliary brushes 311 is higher than the top of the main brush 325 .

[0075] In this embodiment, by arranging the brush holder 312 on the second wheel disc 310, the auxiliary brush 311 protrudes from the main brush 325, so that during the washing process, the clothes can contact the main brush 325 and the auxiliary brush 311 at multiple angles. At the same time, the clothes continuously adjust their postures as the first wheel disc 320 and the second wheel disc 310 rotate, which greatly increases the ratio of the area of ​​the pulsator assembly 300 that scrubs the clothes to the overall area of ​​the clothes.

[0076] The present invention also provides a control method applied to the above-mentioned washing device. In the washing device, at least the output part 210 includes a central rotating shaft 211 and a first flange shaft 212 concentrically sleeved on the outside of the central rotating shaft 211. In addition, the central rotating shaft 211 is fixedly connected to the second wheel disc 310, and the first flange shaft 212 is fixedly connected to the first wheel disc 320.

[0077] During the washing process, the transmission and distribution paths of the transmission gears inside the reducer 200 are controlled and adjusted so that the central shaft 211 and the first flange shaft 212 of the reducer 200 rotate in opposite directions, thereby driving the first wheel 320 and the second wheel 310 to rotate respectively.

[0078] In this embodiment, by controlling the first wheel and the second wheel to rotate in opposite directions according to the washing action requirements, the relative friction and contact effect between the first wheel and the second wheel and the clothes is improved, thereby improving the washing efficiency of the clothes.

[0079] like Figure 1 and Figure 2As shown, in another embodiment of the present invention, a control method is introduced that can ensure that the impeller assembly 300 and the barrel body 100 in the washing device cooperate with each other and operate smoothly.

[0080] The washing device comprises a barrel body 100. The output part 210 comprises a second flange shaft 213 which is concentrically sleeved on the outer side of the first flange shaft 212. The second flange shaft 213 is fixedly connected to the bottom wall of the barrel body 100.

[0081] During the dehydration of the clothes, the transmission and distribution paths of the transmission gears inside the reducer 200 are controlled and adjusted so that the central shaft 211, the first flange shaft 212 and the second flange shaft 213 of the reducer 200 rotate in the same direction and at the same speed.

[0082] In this embodiment, by controlling the first wheel 320 and the second wheel 310 to rotate in the same direction as the barrel body 100, torque in the same direction can be generated on the clothes at multiple positions, thereby preventing the dehydration time of the clothes from being prolonged due to the uncoordinated rotation of the impeller assembly 300 and the barrel body 100. The clothes can be driven by the first wheel 320, the second wheel 310 and the barrel body 100 to rotate at the same speed as the barrel body 100 in the shortest time, thereby reducing the running time of the dehydration stage and improving the dehydration efficiency.

[0083] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
