Description
Technical Field
The invention belongs to the technical field of clothes treatment equipment, and particularly relates to washing equipment and a dehydration method thereof.
Background
The washing process of the existing washing apparatus generally includes washing, rinsing and dehydrating stages. In the washing or rinsing stage, the washing water and the laundry are turned over together with the rotation of the washing drum, so that the laundry can rub against the washing water and the drum wall, thereby washing the laundry. In this case, different clothes or different parts of the same clothes may be entangled during tumbling and are difficult to be disentangled in a subsequent tumbling action, thereby causing the weight of the entire clothes to be unevenly distributed in the washing drum, causing the washing drum to be eccentric, and affecting the high-speed rotation of the washing drum during dehydration. Not only reduces the dewatering efficiency, but also generates larger working noise when the washing drum rotates.
At present, when the washing drum is eccentric in the dewatering stage, the existing washing equipment tries to improve the winding condition of the clothes by means of speed reduction or water re-feeding rotation. The disadvantages of this adjustment approach are: the above-mentioned adjustment step needs to be carried out at least once in the dehydration process, which not only can generate the energy consumption caused by the rotation of the washing drum, but also can increase the water consumption of the washing equipment and reduce the energy-saving effect of the washing equipment.
Accordingly, there is a need in the art for a new washing apparatus and a dehydration method thereof to solve the above problems.
Disclosure of Invention
In order to solve the above problems in the prior art, i.e. to solve the problem that the existing washing equipment needs to perform at least one speed reduction rotation step or water inlet rotation step in the dehydration process, and the energy consumption and water consumption parameters of the washing equipment are increased, the invention provides a dehydration method for the washing equipment, wherein the washing equipment comprises a washing drum, the washing drum comprises an outer drum and an inner drum arranged in the outer drum, and the dehydration method comprises the following steps: step S1: rotating the inner drum at a spin-drying rotational speed after the washing device drains water; step S2: judging whether the inner cylinder has a cylinder collision condition: step S3: and selectively enabling the inner cylinder to suddenly stop and level according to the judgment result of whether the inner cylinder has a cylinder collision condition or not.
In a preferred embodiment of the above dehydration method, the step S3 includes: step S31: and if the inner cylinder has a cylinder collision condition, the inner cylinder is suddenly stopped and leveled.

In a preferred embodiment of the above dehydration method, after step S31, the dehydration method further includes: step S4: so that the inner cylinder rotates forwards and backwards alternately.
In a preferred embodiment of the above dehydration method, after step S31, the dehydration method further includes: step S5: accumulating the once sudden stop leveling times, and judging whether the current sudden stop leveling times reach a first set time; step S6: if the current scram leveling times do not reach the first set times, returning to the step S1; step S7: if the current sudden stop leveling times reach the first set times, resetting the sudden stop leveling times, simultaneously accumulating the one-time sudden stop leveling failure times and judging whether the current sudden stop leveling failure times reach the second set times; step S8: and selectively enabling the washing equipment to execute a water inlet balance command according to the judgment result of whether the current sudden stop leveling failure times reach the second set times.
In a preferred embodiment of the above dehydration method, the step S8 includes: step S81: if the current scram leveling failure times do not reach the second set times, enabling the washing equipment to execute a water inlet balance command and returning to the step S1; step S82: and if the current scram leveling failure times reach the second set times, enabling the washing equipment to send leveling request information.

The present invention also provides a washing apparatus including a controller for performing any one of the above-described dehydration methods.
As can be understood by those skilled in the art, the dewatering method of the present invention can shake down the top-level clothes in the stacked clothes by leveling the inner drum of the washing device, so as to shake up the entangled clothes, thereby adjusting the uniform distribution of the clothes in the inner drum. The wound and stacked clothes are shaken off by utilizing the sudden stop inertia of the inner drum, so that the clothes do not need to be shaken off by rotating the inner drum for a long time, and the power consumption of the clothes uniformly distributed in the inner drum is reduced. Meanwhile, the emergency stop leveling mode does not need to immerse the clothes, so that the step of water re-feeding before uniform distribution of the clothes is omitted, the integral operation time of the washing equipment is shortened, the water consumption of the washing equipment is reduced, and the waste of water resources is avoided.

fig. 2 is a detailed step flow diagram of a preferred embodiment of the dehydration method for a washing apparatus of the present invention.
Detailed Description
It will be appreciated by those skilled in the art that in the description of the invention, although the steps of the control method of the invention are described in a particular order in the present application, the order is not limiting and that the steps may be performed in a different order by those skilled in the art without departing from the basic principles of the invention.
Based on the problems that the prior washing equipment needs to carry out at least one speed reduction rotation step or water inlet rotation step in the dehydration process and the energy consumption and water consumption parameters of the washing equipment are increased, the invention provides a dehydration method for the washing equipment, which aims to promote clothes to be uniformly distributed in an inner cylinder in an emergency stop mode and avoid consuming a large amount of electric energy and water when the washing equipment is uniformly distributed as far as possible.
Referring first to fig. 1, fig. 1 is a flow chart illustrating major steps of a dehydration method for a washing apparatus according to the present invention. As shown in fig. 1, the present invention relates to a dehydration method for a washing apparatus, wherein the washing apparatus includes a washing tub including an outer tub and an inner tub disposed in the outer tub. The dehydration method for the washing apparatus includes:
step S1: after the washing equipment drains water, the inner cylinder rotates at a dehydration rotating speed;
step S2: judging whether the inner cylinder has a cylinder collision condition:
step S3: and selectively enabling the inner cylinder to suddenly stop and level according to the judgment result of whether the inner cylinder has a cylinder collision condition or not.
In step S1, the "spin-drying rotation speed" is the set maximum rotation speed that can be achieved during the inner drum spin-drying. If the dewatering speed is 150r/min, the inner drum needs to increase the rotating speed from zero to 150/min at a set increasing speed rate, and then continuously rotates at the rotating speed of 150 r/min.
When the washing machine starts to dehydrate, the washing water introduced when the laundry is washed or rinsed in the drum is first drained from the drum. After the washing water in the inner drum is discharged, the inner drum is increased to the set dehydration speed at a certain speed increasing rate and continuously rotates, so that the clothes can be dehydrated.
In step S2, it is determined whether the rotation state of the inner cylinder is balanced by determining whether the inner cylinder has hit the inner cylinder. In the process that the inner cylinder rotates at a certain speed or at the maximum rotating speed, if the rotating state of the inner cylinder is balanced and the situation of cylinder collision does not occur, the gravity center of the inner cylinder is stable, and the cylinder body of the inner cylinder cannot be inclined during rotation. If the rotating state of the inner cylinder is unbalanced, the gravity center position of the inner cylinder is changed along with the rotating action, the gravity center is unstable, and the cylinder body of the inner cylinder can be inclined when rotating and collide with the inner wall of the outer cylinder.
The detection method used when judging whether the inner cylinder has a cylinder collision condition is not limited. As an example, an offset amount between the inner cylinder with respect to its original installation position may be acquired and whether the rotation state of the inner cylinder is balanced may be judged by a specific value of the offset amount. Specifically, the displacement sensor can be arranged between the outer cylinder and the inner cylinder, so that the displacement offset of the inner cylinder can be acquired through the displacement sensor, and whether the inner cylinder collides with the inner cylinder or not can be judged.
In step S3, the phrase "leveling the inner drum by suddenly stopping" refers to shaking off the laundry in the inner drum so that the inner drum stops rotating in a short time, and scattering the wound and stacked laundry in the inner drum by using the inertia of the inner drum at the time of sudden stop of the inner drum, so as to improve the condition that the laundry is locally stacked in the inner drum and the center of gravity of the inner drum containing the laundry is deviated from a set position.
In the above steps S1 to S3, when the inner drum rotates at a high speed to dehydrate the clothes, the rotation state of the inner drum is monitored and judged so as to selectively make the inner drum stop suddenly according to the specific rotation condition whether the inner drum collides with the drum, thereby adjusting the eccentric state of the inner drum, improving the collision condition of the inner drum, and adjusting the unbalance condition of the inner drum in a water-saving and electricity-saving leveling manner.
Further, the step S3 specifically includes:
step S31: if the inner cylinder has a cylinder collision condition, the inner cylinder is stopped suddenly and leveled.
In step S31, if the inner cylinder hits the inner cylinder, it is described that the inner cylinder is unbalanced and the center of gravity is unstable. At the moment, the inner drum is made to make an emergency stop action, so that the clothes are uniformly distributed in the inner drum again by using the inertia effect when the inner drum is in the emergency stop.
In a possible implementation, the step S3 further includes:
step S32: if the inner cylinder does not collide with the cylinder, the inner cylinder is not scram and leveled and the process returns to the step S1.
In the above step S32, if the inner cylinder does not collide with the inner cylinder, it indicates that the inner cylinder is rotating well, at the expected speed-up state or continuously rotating at the maximum rotating speed, and the inner cylinder is in a balanced rotating state, and it is sufficient to directly return to the step S1 to maintain the current state of the inner cylinder without any adjustment, so as to detect and determine the subsequent rotating state of the inner cylinder.
In another possible embodiment, the step S3 further includes:
step S33: if the inner cylinder does not collide, judging whether the washing equipment completes dehydration;
step S34: if the washing apparatus does not complete the dehydration, returning to step S1;
step S35: if the washing apparatus completes the dehydration, the dehydration process of the washing apparatus is finished.
In the above-described steps S33 to S35, before returning to step S1, it is necessary to determine the progress of dehydration of the washing apparatus. If the dehydration process of the washing equipment is about to be terminated, even if the last rotation of the washing equipment is taken as a cylinder collision action, no leveling action is needed after the dehydration is judged to be finished, and whether the rotation state of the inner cylinder in the dehydration process is good or not is not needed to be continuously monitored, so that the process is not needed to return to the step S1, and the operation of the program is finished. If the dehydration process of the washing apparatus is not completed, it is required to return to step S1 to continuously monitor the rotation state of the inner tub in order to opportunistically level the inner tub which is out of balance rotated.
As an example, the manner of determining whether the washing apparatus completes the dehydration may be: the remaining dehydration time period of the washing apparatus is acquired so as to judge whether the dehydration is completed by judging whether the remaining dehydration time period is equal to zero. And if the residual dewatering time length is zero, finishing dewatering, and if the residual dewatering time length is more than zero, finishing dewatering.
Preferably, after the above step S31, the dehydration method for a washing apparatus of the present invention further comprises:
step S4: so that the inner cylinder rotates forward and backward alternately.
In the above step S4, the alternating forward and reverse rotation of the inner cylinder means that the inner cylinder is rotated forward at least once and then rotated backward at least once. The inner drum is repeatedly subjected to positive and negative alternate rotation actions for a plurality of times, so that the clothes in the inner drum are shaken after the inner drum stops suddenly, the uniform distribution effect of the clothes is further promoted, and the shaken clothes are further dispersed. As an example, the steps may specifically be: the inner cylinder is rotated in the forward direction for one circle and then rotated in the reverse direction for one circle, and the inner cylinder is continuously rotated for three times in an alternating manner, so that the step is completed. The number of revolutions of the inner cylinder in forward/reverse rotation and the number of alternate rotation actions of the inner cylinder can be set according to actual leveling requirements.
In a more specific embodiment, after step S31, the dehydration method for a washing apparatus of the present invention further comprises:
step S5: accumulating the once sudden stop leveling times, and judging whether the current sudden stop leveling times reach a first set time;
step S6: if the current scram leveling times do not reach the first set times, returning to the step S1;
step S7: if the current sudden stop leveling times reach a first set time, resetting the sudden stop leveling times, simultaneously accumulating one sudden stop leveling failure time and judging whether the current sudden stop leveling failure time reaches a second set time;
step S8: and selectively enabling the washing equipment to execute a water inlet balance command according to the judgment result of whether the current sudden stop leveling failure times reach the second set times.
In the above steps S5 to S8, the "water inlet balance command" is to adjust the position of the center of gravity of the inner tub by the buoyancy of the washing water in the immersed state of the laundry in conjunction with the leveling operation of the inner tub after the washing tub is again filled with water.
After the inner cylinder is suddenly stopped and leveled each time, the sudden stop leveling times are accumulated. Meanwhile, by taking the first set frequency as a boundary, if the frequency of leveling the inner drum by sudden stop does not reach the first set frequency, the current scattered state of the clothes is easy to level, whether the inner drum collides with the outer drum can be continuously monitored, and the first set frequency is reached when the inner drum collides with the outer drum, the current scattered state of the clothes is difficult to level, and when the inner drum collides with the outer drum, the balance state of the inner drum is difficult to adjust by continuously and repeatedly making the inner drum suddenly stop, namely the sudden stop leveling mode fails. At the moment, accumulating the times of once scram leveling failure, taking the second set time as a limit, judging whether the inner cylinder with serious gravity center offset has the possibility of promoting the clothes to be uniformly distributed in the inner cylinder in an automatic leveling mode according to the judgment result of whether the times of scram leveling failure reaches the second set time, and combining with a water inlet balancing command to try to level the inner cylinder again when the inner cylinder has the possibility of promoting the clothes to be uniformly distributed in the inner cylinder in an automatic leveling mode according to the specific judgment result.
Further, the step S8 includes:
step S81: if the current scram leveling failure times do not reach the second set times, the washing equipment executes a water inlet balance command and returns to the step S1;
step S82: and if the current sudden stop leveling failure times reach a second set time, the washing equipment sends leveling request information.
In the above step S81, if the current scram leveling failure frequency does not reach the second set frequency, it indicates that the inner drum has the possibility of promoting the uniform distribution of the clothes in the inner drum through the automatic leveling manner, at this time, the washing device executes the water inlet balancing command, tries to level the inner drum again in combination with the leveling action of the inner drum after the water is fed, and returns to step S1 after the water inlet balancing command is ended, and the inner drum continues to perform the rotation action during the dehydration during the attempt, so as to continue to monitor the rotation state of the inner drum.
In the above step S82, the "leveling request information" is information issued by the washing apparatus to remind the user that the drum is in a serious unbalance state currently, and to request the user to manually adjust the distribution state of the laundry in the drum. In practical application, the leveling request message may include at least one of light message, sound message (special sound prompt message such as voice broadcast message or buzzer sound), and image-text message. Depending on the specific type of leveling request information, this may be issued by a corresponding module of the washing apparatus. For example, when the leveling request message is light message/sound message/image-text message, the message may be sent through a sound module/display module such as an indicator light/voice broadcast module or a buzzer. Or, the leveling request information can also be data information which is transmitted to the Bluetooth sound box or the mobile device through the communication module of the washing device to prompt the user.
If the current sudden stop leveling failure times reach the second set times, the possibility that the inner drum does not force the clothes to be uniformly distributed on the inner drum in an automatic leveling mode is indicated, and at the moment, the uniform distribution of the clothes in the inner drum cannot be realized even if the inner drum rotates in any mode. Therefore, the user is reminded to carry out manual leveling by sending out leveling request information so as to enable the inner cylinder to continuously complete the dehydration process, and the phenomenon that the dehydration process is laid aside and the running time of the washing equipment is prolonged unconsciously is avoided.
Further, as an example, the above step S81 includes:
step S811: feeding water into the washing equipment;
step S812: the inner cylinder is rotated at a leveling rotation speed.
In the above steps S811 to S812, after the water is completely supplied into the washing tub, the closely entangled laundry is dispersed by rotating the inner tub at a suitable rotation speed for easily shaking the laundry. For example, the leveling rotation speed may be set to 93 r/min. Of course, the operation of the inner cylinder rotation in the intake water balance command is not limited, and for example, in addition to the above examples, the inner cylinder may be rotated alternately left and right for a set time.
Continuing again with fig. 2, fig. 2 is a detailed step flow diagram of a preferred embodiment of the dewatering method for a washing apparatus of the present invention. As shown in fig. 2, as a most preferred embodiment, the dehydration method for a washing apparatus of the present invention specifically includes:
step S1: after the washing equipment drains water, the inner cylinder rotates at a dehydration rotating speed;
step S2: judging whether the inner cylinder has a cylinder collision condition or not;
step S31: if the inner cylinder has a cylinder collision condition, the inner cylinder is stopped suddenly and leveled;
step S33: judging whether the washing equipment completes dehydration or not;
step S34: if the washing apparatus does not complete the dehydration, returning to step S1;
step S35: if the washing equipment finishes the dehydration, the dehydration process is finished.
In the case of scram leveling of the inner barrel:
step S4: the inner cylinder rotates forwards and backwards alternately;
step S5: accumulating the once sudden stop leveling times, and judging whether the current sudden stop leveling times reach a first set time;
step S6: if the current scram leveling times do not reach the first set times, returning to the step S1;
step S7: if the current sudden stop leveling times do not reach the first set times, resetting the sudden stop leveling times, simultaneously accumulating the sudden stop leveling failure times and judging whether the previous sudden stop leveling failure times reach the second set times;
step S811: if the front scram leveling failure times do not reach the second set times, the washing equipment is enabled to be supplied with water;
step S812: rotating the inner cylinder at a leveling rotation speed;
in the case where step S811 or step S812 is executed, returning to step S1 at the same time;
step S82: and if the number of times of the previous scram leveling failure reaches a second set number of times, enabling the washing equipment to send leveling request information.
In summary, the dewatering method for the washing device of the present invention can cause the top-layer clothes to shake down and scatter the entangled clothes in the stacked clothes by making the inner drum of the washing device suddenly stop, so as to adjust the uniform distribution of the clothes in the inner drum. The stacked clothes are shaken off by utilizing the inertia of the sudden stop of the inner drum, so that the clothes do not need to be shaken off by rotating the inner drum for a long time, and the power consumption of the clothes uniformly distributed in the inner drum is reduced. Meanwhile, the emergency stop leveling mode does not need to immerse the clothes, so that the step of water re-feeding before uniform distribution of the clothes is omitted, the integral operation time of the washing equipment is shortened, the water consumption of the washing equipment is reduced, and the waste of water resources is avoided. In addition, under the condition that the leveling can not be carried out in an emergency stop mode, the success rate of automatic leveling of the washing equipment can be further increased by combining a water inlet balance mode, a leveling request is sent to a user when the washing equipment can not be automatically leveled, and the multiple leveling modes are combined, so that the time that the inner cylinder is continuously unbalanced and can not be normally dewatered is shortened to the maximum extent, and the integral operation efficiency of the washing equipment is ensured.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
