The cleaning equipment is used for cleaning dirt. A washing machine is a typical washing apparatus, which generally has an inner tub for loading laundry or the like to be washed, and an outer tub nested outside the inner tub. When the washing machine washes or dehydrates, the inner drum rotates, because the mass distribution of clothes loaded in the inner drum is uneven, the inner drum vibrates, and the inner drum transmits the vibration to the outer drum through the driving device.

The traditional damper has constant damping value, the damping value can not be correspondingly changed along with the difference of the running state of the washing machine, the washing machine adopts the same damping value in the washing stage and the dehydration stage, the damping effect is poor, the low damping characteristics of high damping and dehydration high-speed stages at the initial washing and dehydration stages can not be ensured, and the washing and dehydration noises are large. The long-term large vibration will cause the washing machine to have a fatigue structure, reduce the service life of the product, and affect the user experience.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The damping device 100 is disposed on the cleaning apparatus and is used for damping the cleaning apparatus. The cleaning device may be a washing machine, and for convenience of description, the washing machine is taken as an example to be described below, and it should be noted that the present invention does not imply that the cleaning device is only a washing machine, and may also be other devices capable of cleaning dirt.
As shown in fig. 1, the damper device 100 is used to damp the outer tub 220 of the washing machine. The washing machine has an inner tub 210 for loading washing materials and an outer tub 220 fitted over the inner tub 210. The motion states of the inner tub 210 and the outer tub 220 are influenced by the driving device, and the outer tub 220 is driven to vibrate when the inner tub 210 vibrates, so that the operation state of the inner tub 210 tends to be stable when the outer tub 220 is damped.
As shown in fig. 2 to 3, the shock absorbing device 100 includes a damping motor part 110 and a transmission part. The damping motor part 110 is similar to a motor in structural principle, and all components which are similar to the existing motor in structure and operation principle and can realize the same function can be called as the damping motor part 110, and the damping motor part 110 can be a complete whole or a plurality of dispersed components (that is, the damping motor part 110 can be a motor which is already processed into a whole, or can be a general term of dispersed components which only have the rotor 111 and the stator 112 and do not have a housing).
As shown in fig. 4, the damping motor part 110 includes a rotor 111 having a rotation shaft 1112 and a stator 112 relatively fixed in position. Specifically, the rotor 111 is provided with the coil 1111, and the stator 112 is provided with a structure capable of generating a magnetic field such as a permanent magnet or an electromagnet (the rotor 111 may be provided with the structure generating a magnetic field, and the stator 112 may be provided with the coil 1111, and only the structure in which the rotor 111 is provided with the coil 1111 and the stator 112 is provided with the structure generating a magnetic field will be described below as an example). The end of the coil 1111 is led out of the stator 112 by carbon brush or other means to form the terminal 1113, the number of the terminals 1113 may be two or more, and the coil 1111 has only two terminals 1113 for example. The two terminals 1113 are connected to each other, and specifically, the two terminals may be directly shorted or connected by using other conductive members. After the terminal 1113 is connected, the coil 1111 cuts magnetic induction lines to generate electromotive force when the rotor 111 rotates, and because the two terminals 1113 are electrically connected, the generated electromotive force forms current in the coil 1111, the current enables the coil 1111 to generate a magnetic field, and the direction of the magnetic induction lines of the magnetic field generated by the coil 1111 is the same as the direction of the magnetic induction lines of the magnetic field generated by the stator 112, so that a repulsive action is generated, and the rotating shaft 1112 is damped in the direction opposite to the current rotating direction when the rotating shaft 111 rotates. Meanwhile, as the angular velocity at which the rotor 111 rotates is greater, the greater the generated current is, the greater the repulsive force is.
The transmission structure is respectively connected with the outer tub 220 and the rotation shaft 1112, and is configured to convert the vibration of the outer tub 220 into the rotation of the rotation shaft 1112, and transmit the damping received after the rotation of the rotation shaft 1112 to the outer tub 220. That is, the transmission mechanism can make the rotation shaft 1112 rotate synchronously when the outer barrel 220 vibrates, and the vibration frequency of the outer barrel 220 is higher or lower corresponding to the rotation angular velocity of the rotation shaft 1112, when the vibration frequency of the outer barrel 220 is higher, the rotation angular velocity of the rotation shaft 1112 is higher, and when the vibration frequency of the outer barrel 220 is lower, the rotation angular velocity of the rotation shaft 1112 is lower. The amplitude of the outer tub 220 per unit time also corresponds to the angular velocity of the rotation of the shaft 1112.
The transmission structure may be any known mechanical structure capable of achieving the above-mentioned functions, and specifically may include the gear 123 and the rack 121. The rack 121 is connected to the outer tub 220, and may be hinged, and the rack 121 vibrates along with the outer tub 220 when the outer tub 220 vibrates. The gear 123 is sleeved on the shaft 1112 and is used for driving the shaft 1112 to rotate, that is, the shaft 1112 rotates along with the gear 123 when the gear 123 rotates. The gear 123 is engaged with the rack gear 121, and the gear 123 is configured to rotate with the vibration of the rack gear 121. That is, when the outer tub 220 vibrates, the rack 121 generates a linear reciprocating motion corresponding to the vibration of the outer tub 220, the rack 121 drives the gear 123 to rotate when performing the linear reciprocating motion, the rotating shaft 1112 of the damping motor part 110 rotates to be damped when the gear 123 rotates, and the generated damping is transmitted to the outer tub 220 by the rack 121 and the gear 123, thereby damping the outer tub 220. The motion transmission process of the gear 123 and the rack 121 structure is very stable, and the motion conversion is uniform (i.e. the magnitude of the vibration displacement of the outer tub 220 has a relatively obvious linear corresponding relationship with the angular speed of the rotation shaft 1112). In other embodiments, the transmission structure may also be a link mechanism, and although the motion conversion of the link mechanism is not uniform enough, the motion transmission process of the link mechanism is stable.
When the rack 121 is fixedly connected with the outer tub 220, the rack 121 can form a linear reciprocating motion along with the vibration of the outer tub 220, but the rack 121 may obstruct the vibration direction of the outer tub 220, so that the joint of the rack 121 and the outer tub 220 is stressed greatly when the outer tub 220 vibrates, and the connection failure is easy to occur. When the rack 121 is hinged to the outer tub 220, the rack 121 does not affect the movement of the outer tub 220, but the rack 121 cannot make a linear reciprocating movement, so that other parts are required to guide the movement of the entries. In one embodiment, the transmission structure further includes a guide 122, the guide 122 is connected to the housing 230 of the washing machine (specifically, the guide 122 may be hinged to the housing 230 of the washing machine), and is formed with a guide groove 1221 for guiding the rack 121, the rack 121 is embedded in the guide groove 1221 and has a stroke moving in a length direction of the guide groove 1221, that is, the rack 121 may linearly reciprocate in the guide groove 1221 with respect to the guide 122. The rack 121 and the outer tub 220 are fixedly connected or hinged, and a guide 122 may be provided to guide the rack 121.
The damping motor part 110 may be positioned at a relatively fixed position of the washing machine, and preferably, the damping motor part 110 may further be fixedly connected to a guide 122, a positioning flange may extend from the guide 122, the stator 112 is positioned on the positioning flange, the rotor 111 may be positioned on the stator 112 or the positioning flange, and the gear 123 on the rotating shaft 1112 of the rotor 111 is engaged with the rack 121 in the guide groove 1221. After the damping motor 110 is fixedly connected to the guide 122, the rack 121 linearly reciprocates relative to the guide 122, so that the gear 123 on the rotating shaft 1112 of the rotor 111 is more compactly engaged with the rack 121, and the motion conversion process between the two is more stable.
In one embodiment, the two terminals 1113 are connected by a controller 113, and the controller 113 is configured to adjust the magnitude of the resistance between the two terminals 1113, so that the magnitude of the damping experienced by the rotor 111 during rotation can be adjusted. When the controller 113 makes the resistance between the two terminals 1113 zero, which is equivalent to the two terminals 1113 being short-circuited, the shaft 1112 will obtain the maximum damping when the shaft 1112 is rotated. When the controller 113 sets the resistance between the two terminals 1113 to infinity, which is equivalent to the disconnection of the two terminals 1113, after the two terminals 1113 are disconnected, no current is generated in the coil 1111 when the rotor 111 rotates, so that the coil 1111 does not excite the magnetic field, and the rotor 111 does not receive damping when rotating. In particular, when the controller 113 controls the resistance between the two terminals 1113 to change from infinity to zero, the damping experienced by the rotor 111 at the same rotation speed will gradually become larger.
When the resistance between the two terminals 1113 can be adjusted, the damping generated by the damping motor part 110 can be adjusted in real time according to the vibration state of the washing machine. For different vibration states of the outer tub 220, an optimal damping value with the best damping effect is corresponding to each vibration state, but the damping value is larger, and the damping effect is better. In a preferred embodiment, a sensor may be provided to monitor the vibration state of the washing machine and give an optimal resistance value corresponding to the vibration state to the controller 113, so that the damping motor 110 generates an optimal damping value to optimize the damping effect of the damping device 100.
Since the vibration source of the washing machine is the inner tub 210 and the rotation state of the inner tub 210 corresponds to the vibration state of the washing machine, the purpose of monitoring the vibration state of the washing machine, particularly the rotation speed of the inner tub 210, can be achieved by monitoring the rotation state of the inner tub 210. The vibration state of the washing machine is related to the rotation speed of the inner tub 210, the inner tub 210 rotates with a resonance rotation speed interval, when the rotation speed of the inner tub 210 of the washing machine is within the interval, the operation state of the inner tub 210 is most unstable, and a large damping is required to be applied to the inner tub 210, so the controller 113 is further configured to minimize the resistance between the two terminals 1113 when the rotation speed of the inner tub 210 is within the resonance rotation speed interval, and to maximize the damping received by the inner tub 210 when the resistance between the two terminals 1113 is minimized. When the rotation speed of the inner tub 210 exceeds the resonant rotation speed range, the operation state of the inner tub 210 tends to be stable, and the resistance value between the two terminals 1113 can be properly increased, thereby reducing the damping of the outer tub 220.
It should be noted that the above-mentioned "the resistance between the two terminals 1113 is minimum" merely means that the resistance value is minimum with respect to all the adjustment values of the controller 113, and may not be zero, that is, a value with zero resistance may not be included in all the adjustment values of the controller 113. In one embodiment, the resonance speed interval may be in a speed range of 120r/min to 200r/min, such as 120r/min, 180r/min, 200 r/min. When the rotation speed of the inner tub 210 reaches this interval, the resistance value between the two terminals 1113 is minimized by adjusting the controller 113. When the rotation speed of the outer tub 220 is in the resonance rotation speed range, the controller 113 may make the resistance between the two terminals 1113 a constant value, or may make the resistance have a variation within a certain range, only when the rotation speed of the outer tub 220 is in the resonance rotation speed range, the resistance between the two terminals 1113 has a minimum value. When the rotation speed of the inner barrel 210 is in other intervals, the resistance value between the two terminals 1113 can be controlled to be changed in a stepwise manner or in a continuous manner.
Since the vibration amplitude of the inner tub 210 is large when the inner tub 210 is just started, and the vibration amplitude of the outer tub 220 is also large when the vibration amplitude of the inner tub 210 is large, the outer tub 220 is required to bear large damping at this time, so that the whole operation of the washing machine is more stable. In one embodiment, the resistance between the two terminals 1113 can be minimized by adjusting the controller 113 when the inner barrel 210 is just started, so as to obtain the maximum damping value for the outer barrel 220. When the inner tub 210 is started for a certain time and the rotation speed is continuously increased, the operation state of the inner tub 210 is relatively stable, and the damping of the outer tub 220 can be properly reduced.
In another aspect, the present invention further provides a drum washing machine including the damping device 100 of any one of the above embodiments. In other embodiments, the damping device 100 in any of the above embodiments may also be disposed in a pulsator washing machine.
The outer tub 220 of the drum washing machine is transversely disposed, one end of the outer tub 220 is used for positioning, the other end of the outer tub 220 is in a suspended state, in order to reduce the bending moment of the positioning end of the outer tub 220, the upper end of the outer tub 220 is connected with a hanging spring 240 (in other embodiments, other bearing components may be provided), the hanging spring 240 is used for bearing the outer tub 220 on one hand, and on the other hand, the outer tub 220 can be properly damped. When the hanging spring 240 is disposed at the upper end of the outer tub 220, the damper device 100 may be disposed at the lower end of the outer tub 220, such that the circumferential force of the outer tub 220 is more uniform. It should be noted that the damper device 100 is disposed at the lower end of the outer tub 220 only means that the connection point between the damper device 100 and the outer tub 220 is located at the lower end of the outer tub 220, and the "lower end of the outer tub 220" is defined as follows: the horizontal plane passing through the axis of the outer tub 220 divides the outer tub 220 into upper and lower parts, the part above the horizontal plane is referred to as the upper end of the outer tub 220, and the part below the horizontal plane is referred to as the lower end of the outer tub 220.

When the direction facing the opening of the outer tub 220 is taken as a reference direction, if the inner tub 210 is rotated clockwise, two damper devices 100 are provided on the left side of the outer tub 220 (here, the left side of the lower end of the outer tub 220 based on the above-mentioned reference direction, the same applies hereinafter), and one damper device 100 is provided on the right side of the outer tub 220; if the inner tub 210 is rotated counterclockwise, two shock-absorbing devices 100 are provided at the right side of the outer tub 220, and one shock-absorbing device 100 is provided at the left side of the outer tub 220.
