Detailed Description
The utility model will be further described with reference to the accompanying drawings.
The self-leveling system of the present utility model can be used for automatic leveling of the washing tub 11 of the washing machine 10, and can also be used for automatic control leveling of other suspended tub bodies, and the washing tub 11 of the pulsator washing machine 10 will be described as an example. As shown in fig. 1, the washing machine 10 includes a washing tub 11, the washing tub 11 includes an outer tub and an inner tub, which are nested together, and the inner tub is generally rotated to perform a washing operation, the outer tub is relatively fixed, and the washing tub 11 is suspended in the washing machine 10 by a plurality of suspension rods 20, for example, suspended inside an outer cabinet by a plurality of suspension rods 20. The self-leveling system of the present utility model further comprises a boom 20 controller and an inclination sensor, wherein the inclination sensor can detect the inclination angle of the washing tub 11 and transmit signals to the boom 20 controller, the boom 20 is controlled by the boom 20 controller to move, and further the height of the hanging washing tub 11 of the boom 20 is increased or decreased so as to correct the height of the washing tub 11 until the washing tub 11 is horizontal, and the boom 20 is in a vertical state, so that the boom 20 is controlled by the boom 20 controller to move so as to realize the automatic leveling of the washing tub 11.
The tilt sensor is preferably disposed on the outer tub of the washing tub 11, and since the inner tub and the outer tub of the washing tub 11 are nested together, wherein the outer tub is fixedly provided, the inner tub is provided with a washing function, the inner tub and the outer tub are concentric with each other, the tilt sensor detects a tilt angle of the washing tub 11 and transmits a detection signal to the boom 20 controller, the boom 20 controls a moving direction and distance of the plurality of booms 20 according to the detected tilt angle, and the boom 20 performs simultaneous leveling of the inner tub and the outer tub during the moving process.
The tilt sensor operates according to basic physical principles, and the velocity is not measurable inside the system, but the acceleration can be measured. If the initial velocity is known, the line speed can be calculated by integration, and thus the linear displacement can be calculated. The inclination angle sensor is an acceleration sensor applying the principle of inertia. When the inclination sensor is stationary, that is, the side surface and the vertical direction have no acceleration, only gravity acceleration acts on the inclination sensor, and the included angle between the vertical axis of gravity and the sensitive axis of the acceleration sensor is the inclination angle detected by the inclination sensor.
As shown in FIG. 3, the self-leveling system of the present utility model further includes a boom span control device 30, where boom span control device 30 may control the direction of movement of boom 20 to ensure that boom 20 is moving within the span range, preventing out-of-span movement of boom 20 and thus out-of-system connection, e.g., out-of-span disengagement of boom 20 from a gear. Boom span control device 30 comprises a drive means, an upper limit 32, a lower limit 33, a limit sensor 31, and possibly a transmission means, when limit sensor 31 detects that boom 20 is moving closer to the lower limit, limit sensor 31 transmits a signal to boom 20 controller, boom 20 controller controls the drive means, and the drive means drives boom 20 to move away from the lower limit; when limit sensor 31 detects that boom 20 is moving closer to the upper limit position, limit sensor 31 transmits a signal to boom 20 controller, and boom 20 controller controls a drive device that drives boom 20 away from the upper limit position.
The boom span control apparatus 30 further includes a shock-absorbing buffer connected to one end of the boom 20 to ensure smoothness during the movement of the boom 20, for example, the shock-absorbing buffer is a shock-absorbing spring 37, and the shock-absorbing spring 37 is connected to one end of the boom 20 to be brought to the shock-absorbing spring 37 to be compressed or pulled up during the movement of the boom 20, thereby enabling the boom 20 to move smoothly.
As shown in fig. 3, the driving device may be a rotation driving device or a linear motion driving device, for example, the driving device may be a motor 34, the transmission device is a transmission gear 35 and an adjusting gear 36, the limit sensor 31 is a distance detection sensor, the limit sensor 31 may detect a distance between an end of the boom 20 and an upper limit or a lower limit, the motor 34 rotates forward or backward to drive the transmission gear 35 to rotate forward or backward, so as to drive the adjusting gear 36 to rotate forward or backward, and the adjusting gear 36 rotates forward or backward to drive the boom 20 to move downward or upward. When the positions of the plurality of suspension rods 20 are close to the lower limit, in order to avoid the suspension rods 20 from being disconnected, the suspension rod 20 controller controls the plurality of suspension rods 20 to move in the direction away from the lower limit, so that the suspension rods 20 move upwards to drive the washing tub 11 to ascend. When the positions of the plurality of suspension rods 20 are close to the upper limit, in order to avoid the suspension rods 20 from being disconnected, the suspension rod 20 controller controls the plurality of suspension rods 20 to move in the direction away from the upper limit, so that the suspension rods 20 move downwards integrally to drive the washing tub 11 to descend integrally. Since the washing tub 11 is generally in a substantially horizontal state, the controller of the boom 20 generally controls the plural booms 20 to move up and down synchronously at the same time when the whole span adjustment is performed. Furthermore, when a portion of boom 20 has approached the span limit value and the remaining booms 20 are in the mid-position, boom 20 controller may also control movement of only boom 20 in which a portion has approached the limit such that boom 20 is away from the limit and in the mid-position, avoiding decoupling boom 20.
As shown in fig. 2 and 4, the method of leveling the washing tub 11 using the self-leveling system of the present utility model or the operation of the self-leveling system of the present utility model includes the following procedures:
detection flow
Taking the pulsator washing machine 10 as an example, when the washing machine 10 leaves a factory, the reference horizontal plane is calibrated first, so that the washing machine is ensuredWhen the washing tub 11 is delivered from the factory, the washing tub 11 is in a horizontal state, the initial inclination angle detected and output by the inclination angle sensor is about xc=0, namely, the factory default leveling is horizontal without inclination angle, namely, the default leveling is horizontal. After the washing machine 10 is installed in a user's home, the washing machine 10 is powered on in a stationary and empty state, and the inclination angle sensor measures the inclination angle of the washing tub 11 with respect to the horizontal plane, and the inclination angle X is output from the inclination angle sensor 0 Filtering to obtain stable inclination angle X 1 。
Reminding process
When an excessive tilt angle is detected, i.e. X 1 When Xmax has been exceeded, i.e., the inclination angle is too large, then the controller of boom 20 acquires the signal from the inclination sensor and outputs a signal to stop adjusting boom 20, and a signal to adjust the installation position of washing machine 10 is sent to the user, for example, by means of a control panel or a voice connected to the controller of boom 20, to alert the user that the installation position of washing machine 10 needs to be adjusted first. Therefore, the self-leveling system or the leveling method of the present utility model is mainly applied to cleaning in which the inclination angle of the washing tub 11 or the suspension rod 20 is not very large, and when the inclination angle is too large, it is necessary to manually move the washing machine 10 to a flatter position, as described above, because the movement of the suspension rod 20 is limited by the range, the inclination angle is too large, the precise leveling cannot be achieved by moving the suspension rod 20 within the range, and only manual rough adjustment can be performed, and the value of Xmax is related to the length of the suspension rod 20, the size of the washing tub 11, and the like.
Adjustment flow
When X1 is<Xmax, the main control board of the washing machine 10 is shown in the range of adjustable range of the boom 20 according to the inclination angle X 1 Comparing Xc, calculating control amounts of lengths of multiple suspenders 20 (for example, four), converting into specific driving or rotating directions (forward rotation or reverse rotation) of the driving device, and finally sending control commands by the suspender 20 controller to enable the driving device to drive the suspender 20 to move, wherein the detection output value X of the inclination angle is always detected in the control process 1 Up to X 1 ≈X 0 (i.e., |X 0 -xc|/|xc|≡1% -3%, i.e. error allowance a). The suspension rods 20 are preferably each individually connected to a controller of the suspension rod 20 for individually connecting the suspension rods 20The moving distance of each boom 20 is controlled. As shown in fig. 3 and 4, due to the travel limit on the boom 20, when the control motor 34 reaches the maximum control travel, the control motor 34 does not execute the tilt angle adjustment action, readjusts the control scheme, for example, the upper limit 32 switch is triggered, then all the boom 20 control motors 34 are stopped, then the motors 34 are reversed, all the booms 20 are moved upwards, the control scheme is executed again, the leveling control is continued, and the leveling control is ensured to be performed within the travel range of the boom 20.
According to the self-leveling system of the utility model, an inclination sensor is arranged on the outer barrel of the washing barrel 11, and a boom 20 which can be controlled to move by a boom 20 controller is arranged, the boom 20 controller controls the moving direction and the moving distance of the boom 20 according to the detection data of the inclination sensor, and the length of the boom 20 is automatically adjusted according to the installation condition, so that the washing barrel 11 is automatically adjusted to reach the level. During the process of adjusting the boom 20 to correct the inclination angle, when the upper limit 33 switch and the lower limit 33 switch are met through a travel limit device arranged on the boom 20, the control motor 34 is powered off, continuous operation is not performed, the control scheme is readjusted, and the process of exceeding the travel of the boom 20 in the control length process is avoided.
While the utility model has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the utility model. In particular, the technical features mentioned in the respective embodiments may be combined in any manner as long as there is no structural conflict.
