Description

Technical Field

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

[0002] Washing machines are essential household appliances in modern family life. The washing machine uses a washing tub to drive the clothes and water flow to rotate to achieve the purpose of cleaning clothes. However, due to the unevenness of the clothes in the washing machine, or the imbalance of the washing machine, the washing machine will inevitably vibrate during operation. Especially during the spin start and spin operation, the outer tub will swing as the motor starts, causing greater vibration and noise.

[0003] At present, in order to solve the problem that washing machines vibrate and generate noise, some washing machines are equipped with vibration damping springs. One end of the vibration damping spring is suspended on the washing machine body, and the other end is suspended on the suspension seat of the washing machine body. When the outer tub shakes or swings, the eccentricity of the outer tub is buffered by the buffering effect of the vibration damping spring, thereby achieving the purpose of vibration reduction.

[0004] However, when the washing machine has a large eccentricity, the vibration cannot be effectively reduced if only the vibration-damping effect of the spring is relied upon; in addition, the vibration of the washing machine cannot be specifically adjusted according to the offset direction and offset amplitude during the vibration process of the washing machine, resulting in low vibration-damping efficiency of the washing machine and long-lasting noise.

[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 problems that the existing washing machines are prone to vibrate and generate noise, and have poor vibration reduction effect and low efficiency, and to provide a washing machine and a control method thereof, so that the washing machine has good vibration reduction effect, high vibration reduction efficiency and generates little noise.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a washing machine, including an inner barrel for holding clothes and washing water, including:

[0008] The vibration reduction device comprises a vibration reduction plate arranged in the inner tub, the vibration reduction plate can move relative to the inner tub to drive the clothes and washing water in the inner tub to move in the horizontal direction;

[0009] A position sensor is provided on the washing machine to detect the displacement direction and displacement amplitude of the washing machine during vibration;

[0010] The controller is electrically connected to the vibration reduction device and the position sensor respectively, and controls the movement of the vibration reduction plate of the vibration reduction device according to the offset direction and offset amplitude detected by the position sensor.

[0011] Furthermore, the vibration damping device also includes a plurality of lifting mechanisms which are circumferentially arranged on the bottom wall of the inner barrel and can move up and down in the vertical direction. The vibration damping plate is arranged relative to the bottom wall of the inner barrel and abuts against the top of the lifting mechanism. The controller is electrically connected to the plurality of lifting mechanisms respectively and controls the movement of the plurality of lifting mechanisms to drive the vibration damping plate to tilt in different directions.

[0012] Furthermore, a plurality of the lifting mechanisms are circumferentially arranged on the edge of the bottom wall of the inner barrel, the shape of the vibration damping plate matches the bottom wall of the inner barrel, and the top of the lifting mechanism abuts against the edge of the vibration damping plate.

[0013] Furthermore, the lifting mechanism includes a lifting rod and a lifting motor, the lifting motor is arranged outside the inner barrel, one end of the lifting rod passes through the bottom wall of the inner barrel and is connected to the vibration damping plate, and the other end is connected to the lifting motor, and the lifting motor drives the lifting rod to move up and down.

[0014] Further, the position sensor is arranged on the upper part of the washing machine;

[0015] Preferably, a balance ring is arranged on the upper part of the inner barrel, and the position sensor is arranged on the balance ring.

[0016] Furthermore, a gravity sensor is provided at the bottom of the inner barrel for detecting the weight of the clothes and washing water in the inner barrel. The gravity sensor is electrically connected to the controller, and the controller controls the movement of the vibration damping plate according to the detected weight, the displacement direction and the displacement amplitude of the washing machine.

[0017] Furthermore, the position sensor is controlled to detect the deviation direction and deviation amplitude of the washing machine, and the vibration damping plate is controlled to move according to the detected deviation direction and deviation amplitude.

[0018] Further, the projection direction of the offset direction on the bottom wall of the inner barrel is determined according to the detected offset direction.

[0019] The lifting mechanism corresponding to the projection direction among the plurality of lifting mechanisms is controlled to rise and / or the lifting mechanism corresponding to the direction opposite to the projection direction is controlled to descend, so as to tilt the vibration reduction plate.

[0020] Further, according to the detected deviation amplitude, the lifting mechanism is controlled to be raised and / or lowered to a height proportional to the deviation amplitude, so that the inclination angle of the vibration damping plate is proportional to the deviation amplitude.

[0021] Furthermore, the gravity sensor is controlled to detect the weight of the clothes and washing water in the inner barrel, and according to the detected weight of the clothes and washing water, the lifting mechanism is controlled to rise and / or fall to a height proportional to the weight of the clothes and washing water.

DETAILED DESCRIPTION

The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0036] 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.

[0037] like Figures 1 to 4 As shown, the present invention discloses a washing machine and a control method thereof. The washing machine comprises an inner tub 1 for holding clothes and washing water, and further comprises:

[0038] A vibration damping device, the vibration damping device comprises a vibration damping plate 2 arranged in the inner tub 1, the vibration damping plate 2 is movably connected to the inner tub wall. The vibration damping plate 2 can move relative to the inner tub 1 to drive the clothes and washing water in the inner tub 1 to move in the horizontal direction;

[0039] The position sensor is arranged on the washing machine and is used to detect the displacement direction and displacement amplitude of the washing machine during vibration.

[0040] The controller is electrically connected to the vibration reduction device and the position sensor respectively. The controller controls the vibration reduction plate 2 of the vibration reduction device to move according to the offset direction and offset amplitude detected by the position sensor.

[0041] Specifically, the position sensor can detect the offset direction and offset amplitude of the washing machine relative to a preset position. The preset position is the position of the washing machine when it does not vibrate. The offset direction refers to the direction of the washing machine relative to the preset position; the offset amplitude refers to the offset degree of the washing machine in the offset direction. The larger the offset amplitude of the washing machine, the greater the offset degree of the washing machine; and vice versa.

[0042] The present invention controls the movement of the vibration damping plate 2 according to the offset direction and offset amplitude of the washing machine, so that the clothes and washing water in the washing machine move in the horizontal direction, the center of gravity shifts in the opposite direction of the offset direction of the washing machine, and the offset amount matches the offset amplitude of the washing machine, thereby effectively reducing the vibration of the washing machine, reducing the noise of the washing machine, and improving the vibration reduction efficiency.

[0043] As an embodiment of the present invention, the vibration damping plate 2 is vertically arranged in the inner tub 1 and can move relative to the peripheral side wall of the inner tub 1. When the position sensor detects the offset direction of the washing machine, the vibration damping plate 2 is controlled to move in the opposite direction of the offset direction to push the clothes and water in the inner tub 1 to move in the opposite direction of the offset direction. Further, the center of gravity is offset in the opposite direction of the offset direction to keep the washing machine balanced and reduce the vibration of the washing machine.

[0044] Specifically, in this embodiment, the vibration reduction device includes a plurality of vibration reduction plates 2. The plurality of vibration reduction plates 2 are circumferentially arranged on the peripheral side wall of the inner tub 1. The plurality of vibration reduction plates 2 are movably connected to the peripheral side wall of the inner tub 1 and can respectively move radially relative to the peripheral side wall of the inner tub, so that the clothes and washing water in the inner tub 1 can move in different directions according to the offset direction and offset amplitude of the washing machine, thereby reducing the vibration of the washing machine and the noise generated by the vibration.

[0045] More specifically, a telescopic rod is provided on the peripheral side wall of the inner tub 1, passing through the peripheral side wall of the inner tub 1 and connected to the vibration damping plate 2. The telescopic rod can be extended relative to the peripheral side wall of the inner tub 1. When the telescopic rod is extended, the vibration damping plate 2 moves to reduce the vibration of the washing machine; when the telescopic rod is retracted, the vibration damping plate 2 is arranged in contact with the peripheral side wall of the inner tub 1, so that the vibration damping plate 2 does not occupy the space of the inner tub 1.

[0046] Furthermore, one end of the telescopic rod is connected to the vibration damping plate 2, and the other end is connected to the output shaft of the telescopic motor. The telescopic motor can drive the telescopic rod to extend and retract, and further drive the vibration damping plate 2 to move. By setting the telescopic motor to drive the telescopic rod to extend and retract, the telescopic efficiency of the telescopic rod is high and easy to control.

[0047] In this embodiment, the vibration damping plate 2 and the telescopic rod are arranged to control the movement of the vibration damping plate 2 of the vibration damping device according to the offset direction and offset amplitude detected by the position sensor to maintain the balance of the washing machine, reduce the vibration of the washing machine, and reduce the noise of the washing machine.

[0048] As another embodiment of the present invention, Figure 1 and Figure 2 As shown, the vibration damping device also includes a plurality of lifting mechanisms 3 which are circumferentially arranged on the bottom wall of the inner tub 1 and can move up and down in the vertical direction. The vibration damping plate 2 is arranged opposite to the bottom wall of the inner tub 1 and abuts against the top of the lifting mechanism 3. The controller is electrically connected to the plurality of lifting mechanisms 3 respectively, and controls the movement of the plurality of lifting mechanisms 3 to drive the vibration damping plate 2 to tilt in different directions. The tilting of the vibration damping plate 2 drives the clothes and washing water in the inner tub 1 to move horizontally, shifts the center of gravity, corrects the vibration of the washing machine, and reduces the generation of noise.

[0049] As an implementation method of this embodiment, a plurality of lifting mechanisms 3 are circumferentially arranged on the bottom wall edge of the inner barrel 1. The shape of the vibration damping plate 2 matches the bottom wall of the inner barrel 1. The top of the lifting mechanism 3 abuts against the edge of the vibration damping plate 2.

[0050] For example, the bottom wall of the inner tub 1 is circular, and the vibration damping plate 2 matches the shape of the bottom wall of the inner tub 1 and is circular. The cross section of the vibration damping plate 2 is smaller than the area of ​​the bottom wall of the inner tub 1. The vibration damping plate 2 is subjected to the force of different lifting mechanisms 3 and can be tilted in different directions to maintain the balance of the washing machine and reduce the generation of noise.

[0051] As an embodiment of the present invention, the lifting mechanism 3 includes a lifting rod 31 and a lifting motor 32. The lifting motor 32 is arranged outside the inner barrel 1. One end of the lifting rod 31 passes through the bottom wall of the inner barrel 1 and is connected to the vibration damping plate 2, and the other end is connected to the output shaft of the lifting motor 32. The lifting motor 32 drives the lifting rod 31 to move up and down.

[0052] The lifting motor 32 can be arranged at the bottom outside the inner tub 1 or on the side wall outside the inner tub 1. The installation position of the lifting motor 32 can be selected according to the actual installation requirements, which not only ensures the normal lifting of the lifting rod 31, but also makes the installation of the washing machine diversified.

[0053] In the present invention, the vibration damping plate 2 matches the bottom shape of the inner tub 1. In addition, the vibration damping plate 2 is in active contact with the inner peripheral side wall of the inner tub 1 and is sealed. This arrangement prevents the washing water and clothes in the inner tub 1 from entering the area between the vibration damping plate 2 and the bottom wall of the inner tub 1, affecting the washing effect. At the same time, the vibration damping plate 2 has a good effect on the washing water and clothes. When the vibration damping plate 2 moves, the center of gravity of the washing water and clothes is more obviously offset, and the vibration damping effect is better.

[0054] As an embodiment of the present invention, the lifting mechanism is a hydraulic lifter. The hydraulic lifter includes a hydraulic column. The hydraulic column passes through the side wall of the inner tub 1 and is connected to the vibration damping plate 2 to drive the vibration damping plate 2 to move and reduce the vibration of the washing machine.

[0055] As another embodiment of the present invention, the position sensor is arranged on the upper part of the washing machine. Since the center of gravity of the washing machine is close to the lower part of the washing machine, the vibration of the upper part of the washing machine is more obvious during the vibration of the washing machine, and the deviation angle and deviation amplitude are relatively large. Therefore, the position sensor is arranged on the upper part of the washing machine, so that the position sensor is more sensitive and can detect the vibration of the washing machine faster and more accurately.

[0056] Preferably, a balance ring is provided on the upper part of the inner tub 1. The position sensor is provided on the balance ring. At present, some washing machines are provided with a balance ring, and the position of the balance ring often represents the position state of the washing machine. The position sensor is provided on the balance ring, so that the position information of the washing machine detected is more accurate.

[0057] As another embodiment of the present invention, a gravity sensor is provided at the bottom of the inner tub 1 for detecting the weight of the clothes and washing water in the inner tub 1. The gravity sensor is electrically connected to the controller, and the controller controls the movement of the vibration damping plate 2 according to the detected weight, the deflection direction and the deflection amplitude of the washing machine.

[0058] Specifically, in a washing machine, when the weight of the clothes and washing water is large, the inertia generated is large, and when the washing machine starts to spin and spins, the deviation amplitude of the washing machine during vibration is large. Therefore, controlling the inclination angle of the vibration-damping plate 2 to be proportional to the weight of the clothes and washing water can effectively reduce the vibration of the washing machine, and the vibration-damping effect is good and the efficiency is high.

[0059] like Figure 3 and Figure 4 As shown, the present invention also provides a control method for a washing machine according to any of the above schemes. The controller of the washing machine controls the position sensor to detect the offset direction and offset amplitude of the washing machine, and controls the movement of the vibration damping plate 2 according to the detected offset direction and offset amplitude. The present invention controls the movement of the vibration damping plate according to the detected offset direction and offset angle, so that the vibration damping effect of the washing machine is better and the vibration damping efficiency is higher.

[0060] Alternatively, a separate server is provided outside the washing machine, and the server is respectively connected to the controller and the position sensor of the washing machine for communication. The position sensor sends information about the detected offset direction and offset amplitude to the server. The server determines whether the vibration damping plate 2 moves based on the information about the offset direction and offset amplitude, and transmits a signal indicating the movement of the vibration damping plate 2 to the controller of the washing machine. The controller controls the movement of the vibration damping plate 2 based on the received information.

[0061] Specifically, the washing machine is turned on, and the position sensor is further turned on to determine whether the washing machine is offset. If the washing machine is offset, the position sensor is controlled to detect the offset direction and offset amplitude of the washing machine. If the washing machine is not offset, the detection is continued.

[0062] The projection direction of the offset direction on the bottom wall of the inner tub 1 of the washing machine is obtained according to the detected offset direction.

[0063] The lifting mechanism 3 corresponding to the projection direction among the plurality of lifting mechanisms 3 is controlled to rise, so that the vibration reduction plate 2 is tilted and the center of gravity is shifted in the opposite direction of the projection direction, so as to keep the balance of the washing machine.

[0064] Alternatively, the lifting mechanism 3 corresponding to the direction opposite to the projection direction is controlled to descend, so that the vibration reduction plate 2 is tilted and the center of gravity is shifted to the direction opposite to the projection direction, so as to maintain the balance of the washing machine.

[0065] Alternatively, the lifting mechanism 3 corresponding to the projection direction among the plurality of lifting mechanisms 3 is controlled to rise and the lifting mechanism 3 corresponding to the opposite direction of the projection direction is controlled to fall at the same time. This effectively shortens the vibration reduction time and has high vibration reduction efficiency.

[0066] Through the above control method, the tilting direction of the vibration-damping plate 2 can be controlled, which effectively reduces the vibration of the washing machine and reduces the noise generated by the washing machine.

[0067] As an embodiment of the present invention, according to the detected deviation amplitude, the lifting mechanism 3 is controlled to be raised and / or lowered to a height proportional to the deviation amplitude, so that the inclination angle of the vibration damping plate 2 is proportional to the deviation amplitude.

[0068] Specifically, when the detected deviation is small, it indicates that the vibration of the washing machine is light, and the lifting height / lowering height / raising and lowering height of the lifting mechanism 3 is controlled to be small, so the washing machine can be effectively controlled to maintain balance, effectively avoiding excessive deviation of the center of gravity, reducing the balancing effect and vibration reduction efficiency, and wasting electric energy.

[0069] When the detected deviation is large, it indicates that the washing machine vibrates more seriously. The lifting height / descending height / lifting and descending height of the lifting mechanism 3 is controlled to be large, which can achieve rapid balancing of the washing machine, effectively improve the vibration reduction efficiency of the washing machine, and reduce the noise generated by the washing machine.

[0070] In this embodiment, according to the detected deviation amplitude, the height to which the lifting mechanism 3 is raised and / or lowered is controlled to be proportional to the deviation amplitude, so that the vibration of the washing machine is reasonably controlled, which not only has a good vibration reduction effect and high efficiency, but also saves energy consumed by vibration reduction, reduces the loss of the washing machine itself, and further improves the user experience.

[0071] As another embodiment of the present invention, the gravity sensor is controlled to detect the weight of the clothes and washing water in the inner barrel 1, and according to the detected weight of the clothes and washing water, the lifting mechanism 3 is controlled to rise and / or fall to a height proportional to the weight of the clothes and washing water.

[0072] Specifically, in a washing machine, when the weight of the clothes and washing water is large, the inertia generated is large, and when the washing machine starts to spin and spins, the deviation amplitude of the washing machine during vibration is large. Therefore, controlling the inclination angle of the vibration-damping plate 2 to be proportional to the weight of the clothes and washing water can effectively reduce the vibration of the washing machine, and the vibration-damping effect is good and the efficiency is high.

[0073] 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, 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.
