Description
Technical Field
The invention belongs to the technical field of washing equipment, and particularly relates to washing equipment and a control method thereof.
Background
With the continuous progress of science and technology, more and more types of washing equipment appear on the market, and people also begin to put higher and higher requirements on the comprehensive performance of the washing equipment. Taking washing machine as an example, in order to effectively improve washing machine's security performance and use and experience, current washing machine all is provided with vibration detection switch. Generally, when the washing machine is operated smoothly, the vibration detection switch is in a closed state; when the load in the washing machine is eccentric, the washing tub of the washing machine will vibrate to impact the casing of the washing machine, and the vibration detecting switch will be in off state. The control mode of the existing washing machine is that the washing machine stops running as long as the vibration detection switch is in an off state; however, the control method is easy to have misjudgment in the application process through user feedback. For example, in the operation process of the washing machine, if a user accidentally taps the upper cover of the washing machine, the vibration detection switch may be in an off state, so that the washing machine stops operating, and the user experience is seriously affected.
Accordingly, there is a need in the art for a new washing apparatus and a control method thereof to solve the above-mentioned problems.

In a preferred technical solution of the above control method for a washing apparatus, the washing apparatus includes a pulsator, and the step of "operating the washing apparatus in a vibration correction mode" includes: causing the washing apparatus to perform a water intake operation; rotating the impeller at a preset rotating speed for a first preset time; enabling the impeller to operate for a second preset duration at a first preset rotation-stop ratio; enabling the impeller to operate at a second preset rotation-stop ratio for a third preset time; causing the washing apparatus to perform a draining operation.
In a preferred embodiment of the above control method for a washing apparatus, the control method further comprises: and if the frequency of the washing equipment running the vibration correction mode reaches the preset frequency, enabling the washing equipment to send an abnormal prompt.
In a preferred embodiment of the above control method for the washing apparatus, the step of "acquiring the duration of the first vibration detection switch being in the off state" and the step of "acquiring the duration of the second vibration detection switch being in the off state" are performed within a third preset time.
In a preferred embodiment of the above method for controlling a washing apparatus, the step of "acquiring a duration of the first vibration detection switch being in the off state" includes: acquiring the duration of the first vibration detection switch at a low level; the step of "acquiring the duration of the second vibration detection switch in the off state" specifically includes: acquiring the duration of the second vibration detection switch at a low level.
In a preferred technical solution of the above control method for a washing apparatus, the first vibration detection switch is a shake switch, and the second vibration detection switch is a safety switch.
The invention also provides washing equipment which comprises a controller, wherein the controller can execute the control method in any one of the preferable technical scheme.
As can be understood by those skilled in the art, in the technical solution of the present invention, the washing apparatus of the present invention includes a first vibration detection switch and a second vibration detection switch, both of which are capable of detecting a vibration condition of the washing apparatus, and when the washing apparatus is operated smoothly, both of which are in a closed state; when the washing device generates a vibration phenomenon, whether instantaneous or continuous, the first vibration detection switch and the second vibration detection switch can be changed from a closed state to an open state. In order to effectively ensure the accuracy of the detection result, the washing equipment is provided with two vibration detection switches, and the operation of the washing equipment is controlled by the detection results of the two vibration detection switches. The control method of the invention comprises the following steps: acquiring the duration of the first vibration detection switch in an off state; acquiring the duration of the second vibration detection switch in an off state; and selectively stopping the washing equipment from operating the current washing mode according to the duration of the first vibration detection switch in the off state and the duration of the second vibration detection switch in the off state. According to the invention, the duration time of the first vibration detection switch in the off state and the duration time of the second vibration detection switch in the off state are jointly used as basic parameters, on one hand, the duration time is used as the basic parameter, so that the condition that the washing equipment generates instantaneous vibration can be effectively eliminated, namely, if the washing equipment generates instantaneous vibration due to certain special conditions, such as the condition that a user carelessly beats the upper cover of the washing equipment, the washing equipment cannot generate a misjudgment phenomenon, and the accuracy of the washing equipment in judging the vibration condition is effectively ensured; on the other hand, the control method further effectively improves the accuracy of the vibration condition judgment of the washing equipment by simultaneously adopting the detection results of the two vibration detection switches, so that the user experience is improved to the maximum extent.
Further, in a preferred technical solution of the present invention, the control method of the present invention can determine whether the washing device really cannot run smoothly according to a comparison result between the duration of the off state of the first vibration detection switch and the first preset time and a comparison result between the duration of the off state of the second vibration detection switch and the second preset time, so that the control method can selectively stop the washing device from running in the current washing mode according to the real running condition of the washing device, thereby effectively ensuring the safe running of the washing device.
Further, in a preferred embodiment of the present invention, if the duration of the first vibration detection switch being in the off state is greater than or equal to the first preset time and the duration of the second vibration detection switch being in the off state is greater than or equal to the second preset time, the controller of the washing device can determine that the washing device does have a continuous vibration phenomenon during the operation process; at this time, the controller can control the washing apparatus to stop operating the current washing mode, so as to effectively protect the washing apparatus.
Furthermore, when the controller determines that the washing equipment has continuous vibration phenomenon in the operation process, the controller can also control the washing equipment to operate a vibration correction mode, so that the washing equipment can automatically solve the problem that the washing equipment cannot stably operate under the condition that a user does not need to perform any operation, and the automation degree of the washing equipment is further improved to the maximum degree.
Further, the controller may control the washing apparatus to perform a water supply operation first when the washing apparatus operates a vibration correction mode during the washing apparatus performs a dehydration operation so that the laundry can be sufficiently spread in water; then, the controller controls the impeller to operate at the preset rotating speed for the first preset time so that clothes can be fully contacted with water; then the controller controls the impeller to operate for the second preset time at the first preset rotation-stop ratio and then operate for the third preset time at the second rotation-stop ratio so as to enable the clothes to be dispersed in water as much as possible and to be uniformly distributed, and therefore the problem of eccentricity caused by the winding of the clothes is effectively solved; finally, the controller controls the washing apparatus to perform a draining operation so that the washing apparatus can continue to perform a dehydrating operation.
Further, in a preferred technical solution of the present invention, if the number of times that the washing apparatus operates in the vibration correction mode reaches a preset number of times, it indicates that the laundry entangled in the washing apparatus cannot be separated only by the vibration correction mode of the washing apparatus, and at this time, in order to effectively ensure the safe operation of the washing apparatus, the controller controls the washing apparatus to send an abnormal reminder so as to remind a user to rearrange the laundry in the washing apparatus, thereby effectively ensuring the stable operation of the washing apparatus.
Further, in a preferred embodiment of the present invention, the step of "acquiring the duration of the first vibration detection switch being in the off state" and the step of "acquiring the duration of the second vibration detection switch being in the off state" need to be completed within the third preset time; it can be understood that, within a third preset time, if the duration of the first vibration detection switch in the off state, which is acquired by the controller, is greater than or equal to the first preset time and the duration of the second vibration detection switch in the off state is greater than or equal to the second preset time, it is more specific that the washing device has started to generate a continuous and rapid vibration phenomenon, so that the accuracy of the determination result is further improved.
Further, in a preferred technical solution of the present invention, the controller obtains a duration time that the first vibration detection switch is at a low level and a duration time that the second vibration detection switch is at a low level as basic parameters; it can be understood that, when the vibration detection switch is in the off state, the vibration detection switch is also in the low level state, and the controller is equivalent to obtaining the time that the vibration detection switch is in the off state by obtaining the duration time that the vibration detection switch is in the low level state, and this obtaining mode has the advantages of accuracy and high efficiency, and the accuracy of the judgment result can be further effectively ensured by obtaining the basic parameters through this mode.
Furthermore, in a preferred technical solution of the present invention, the first vibration detection switch is a shake switch, and the second vibration detection switch is a safety switch; as can be understood by those skilled in the art, the shaking switch and the safety switch have different structures, so that the shaking switch and the safety switch have different sensitivity degrees to different types of vibration modes.

Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. For example, although the steps of the method of the present invention are described herein in a particular order, these orders are not limiting, and one skilled in the art may perform the steps in a different order without departing from the underlying principles of the invention. The control method of the present invention will be described in detail below by taking the washing apparatus as a washing machine as an example; it will be understood by those skilled in the art that although the preferred embodiment is described in connection with the case where the washing apparatus is a washing machine, it is apparent that the washing apparatus may be other apparatuses having a washing function as long as the washing apparatus includes a vibration detection switch.
Specifically, in the preferred embodiment, the washing machine includes a box, a washing tub disposed in the box, and a tray connected to the box, wherein a shaking switch and a safety switch are disposed on the tray, and both the shaking switch and the safety switch are used for detecting the vibration condition of the washing machine. In the using process of the shaking switch and the safety switch, when the washing machine runs stably, the shaking switch and the safety switch are both in a closed state and output a high level; when the washing tub generates a vibration phenomenon and reaches the respective set maximum vibration amplitudes, both the shaking switch and the safety switch may be turned off to output a low level. It can be understood by those skilled in the art that although the shaking switch and the safety switch are described in the preferred embodiment as being disposed on the base of the washing machine; however, the shaking switch and the safety switch may be disposed at other positions of the washing machine, as long as the shaking switch and the safety switch can detect the vibration of the washing machine. Further, although the first vibration detection switch described in the present preferred embodiment is a shake switch, the second vibration detection switch is a safety switch; however, it is obvious to the skilled person that other types of vibration detection switches can be selected according to the actual use requirement, i.e. the present invention does not set any limit to the specific types of the first vibration detection switch and the second vibration detection switch.
Further, the washing machine further comprises a controller, and the controller can operate the control method of the invention, namely the controller can acquire the vibration condition of the washing machine through the shaking switch and the safety switch. As a preferable mode, the controller can acquire the durations of the open state and the closed state of the vibration switch and the safety switch by acquiring the durations of the low level and the high level of the vibration switch and the safety switch, respectively, and can also control the operation of the washing machine according to the detection results of the vibration switch and the safety switch. Of course, this description is not limiting, and the controller may obtain the durations of the open state and the closed state of the shaking switch and the safety switch in other manners; for example, the controller may further obtain the duration of the rocking switch in the open state and the closed state by obtaining a distance between two contacts of the rocking switch. It should be noted that the controller may also only obtain the duration of the shaking switch and the safety switch in the off state, and not obtain the duration of the shaking switch and the safety switch in the on state. It can be understood by those skilled in the art that the present invention does not impose any limitation on the specific structure and model of the controller, and the controller may be an original controller of the washing machine or a controller separately provided to perform the control method of the present invention.
Referring first to fig. 1, a flow chart of main steps of the control method of the present invention is shown. As shown in fig. 1, based on the washing machine described in the preferred embodiment, the control method of the present invention mainly includes the following steps:
s1: acquiring the duration of the shaking switch in the off state;
s2: acquiring the duration of the safety switch in the off state;
s3: and selectively stopping the washing machine from operating in the current washing mode according to the duration of the shaking switch in the off state and the duration of the safety switch in the off state.
Further, during the operation of the washing machine, the controller may control the washing machine to perform steps S1 and S2; in step S1, the controller can obtain the duration of the shaking switch being in the off state in real time; in step S2, the controller can acquire the duration of time that the safety switch is in the off state in real time; of course, the execution order of steps S1 and S2 may be changed. It should be noted that, the invention does not limit the manner of obtaining the duration time of the off state of the shaking switch and the safety switch by the controller, and a technician can select the obtaining manner by himself according to the use requirement; for example, the controller may obtain the duration of the shaking switch being in the off state by obtaining the duration of the shaking switch being at a low level, or the controller may also obtain the duration of the shaking switch being in the off state by obtaining a distance between two contacts of the shaking switch, that is, as long as the controller can obtain the duration of the shaking switch and the safety switch being in the off state. It should be noted that although the shaking switch and the safety switch are described as being in the off state in the present application, this is not a limitation to the present invention, and those skilled in the art may also describe the shaking switch and the safety switch as being in the on state as needed, that is, the shaking switch and the safety switch are off in the normal state and are on when the washing machine vibrates in a large amplitude, and such changes do not depart from the basic principle of the present invention and thus will fall within the protection scope of the present invention.
Further, in step S3, the controller can selectively stop the washing machine from operating in the current washing mode according to the duration of the shaking switch being in the off state and the duration of the safety switch being in the off state, and of course, a technician can set specific conditions for stopping the washing machine from operating in the current washing mode by himself; for example, the controller may compare the durations of the shaking switch and the safety switch in the off state with different preset times, or the controller may compare the durations of the shaking switch and the safety switch in the off state with different preset mapping relationships, so that the controller may selectively stop the washing machine from operating in the current washing mode according to the durations of the shaking switch and the safety switch in the off state. It can be understood by those skilled in the art that it is within the scope of the present invention as long as the control method controls the current operation state of the washing machine with the duration of the shaking switch and the safety switch in the off state as its basic parameters.
Reference is now made to fig. 2, which is a flow chart of the steps of a preferred embodiment of the control method of the present invention. As shown in fig. 2, based on the washing machine in the preferred embodiment, the preferred embodiment of the control method of the present invention specifically includes the following steps:
s101: acquiring the duration of the shaking switch at a low level;
s102: acquiring the duration of the safety switch at a low level;
s103: if the duration time of the shaking switch at the low level is greater than or equal to the first preset time and the duration time of the safety switch at the low level is greater than or equal to the second preset time within the third preset time, stopping the washing machine from executing the dewatering operation;
s104: causing the washing machine to perform a water supply operation;
s105: rotating the impeller at a preset rotating speed for a first preset time;
s106: the impeller is driven to rotate at a first preset rotation-stop ratio for a second preset time;
s107: enabling the impeller to operate at a second preset rotation-stop ratio for a third preset time;
s108: causing the washing machine to perform a draining operation;
s109: the washing machine is caused to continue to perform the dehydrating operation.
Further, the controller may control the washing machine to perform steps S101 and S102 during the operation of the washing machine for dehydration; in step S101, the controller can obtain the duration of the low level of the shaking switch in real time; in step S102, the controller can obtain the duration of the safety switch at the low level in real time; of course, the execution order of step S101 and step S102 may be changed, and step S101 and step S102 may also be executed simultaneously. It should be noted that, although the preferred embodiment obtains the duration of the shake switch and the safety switch in the off state by obtaining the duration of the shake switch and the safety switch in the low level respectively; however, it is obvious to a skilled person that other modes can be selected by himself according to the use requirement, as long as the controller can obtain the duration of the off state of the shaking switch and the safety switch. It can be understood that, in the preferred embodiment, when the controller acquires that the shaking switch or the safety switch is at a low level, the controller collects the duration of the shaking switch or the safety switch; of course, the controller may also obtain the duration of time that the shaking switch or the safety switch is at the low level by calculating the time difference between two times of high level. It should also be noted that although the preferred embodiment is described with reference to the process of the washing machine performing the spinning operation, it is obvious that the control method of the present invention can also be used in the process of the washing machine performing other operations, without departing from the basic principle of the present invention.
Further, in step S103, if the duration of the shaking switch being at the low level is greater than or equal to the first preset time and the duration of the safety switch being at the low level is greater than or equal to the second preset time within a third preset time, the controller controls the washing machine to stop operating the current washing mode, i.e., to stop the washing machine from performing the dehydration operation, and to operate the washing machine in the vibration correction mode, which in the preferred embodiment includes steps S104 to S108. It should be noted that, although the vibration correction mode described in the present preferred embodiment includes steps S104 to S108; however, it is obvious that such description is exemplary, i.e., a skilled person can set the specific operation performed by the vibration correction mode at will according to the actual situation.
Further, as a preferred embodiment, in step S103, if the duration of the low level of the shaking switch is greater than or equal to the first preset time, the counter of the shaking switch counts once; if the duration time of the safety switch at the low level is greater than or equal to the second preset time, the counter of the safety switch counts once; and if the controller judges that the counts of the counter of the shaking switch and the counter of the safety switch are both greater than 1 within a third preset time, the controller judges that the washing machine really generates continuous strong vibration, at the moment, the controller controls the washing machine to stop executing the dehydration operation, and the counts of the counter of the shaking switch and the counter of the safety switch are both reset to zero so as to be counted again later. It should be noted that if the controller does not detect that the duration time of the low level of the shaking switch is greater than or equal to the first preset time and the duration time of the low level of the safety switch is greater than or equal to the second preset time within the third preset time, the controller controls the washing machine to maintain the current washing mode. As will be understood by those skilled in the art, the first preset time and the second preset time are both preferably 48 milliseconds, and the third preset time is 200 milliseconds; of course, the technician can set the first preset time, the second preset time and the third preset time according to the actual use condition, as long as the controller can accurately distinguish whether the washing machine really appears the continuous vibration phenomenon through the first preset time, the second preset time and the third preset time. In addition, it should be noted that, although the third preset time is used in the preferred embodiment, it is obvious that the control method may also stop the washing machine from performing the spin-drying operation when the controller detects that the duration of the shaking switch being at the low level is greater than or equal to the first preset time and the duration of the safety switch being at the low level is greater than or equal to the second preset time.
Further, as a preferred embodiment, in step S103, if the counter of the shake switch counts before the counter of the safety switch, the washing machine is caused to execute a first vibration correction mode; and if the counter of the shaking switch does not count before the counter of the safety switch, causing the washing machine to perform a second vibration correction mode. Of course, this is just a preferred embodiment, and the first vibration correction mode may also perform the same operation as the second vibration correction mode, i.e., the controller directly controls the washing machine to perform the vibration correction mode. In addition, a technician can set the specific operation of the first vibration correction mode and the second vibration correction mode according to the actual use requirement.
Further, in step S104, the controller controls the washing machine to perform a water supply operation; preferably, the controller controls the washing machine to supply water to the rinsing water level, but this is not limitative, and a technician may set the water supply level by himself/herself. Next, in step S105, the controller controls the pulsator of the washing machine to operate at the preset rotation speed for the first preset time period, so that the clothes can be sufficiently spread in the water. It should be noted that, preferably, the preset rotation speed is the washing rotation speed of the pulsator; in addition, when the washing machine operates in a first vibration correction mode, the first preset time period is 2 minutes; when the washing machine operates in the second vibration correction mode, the first preset time period is 1 minute. In step S106, the controller controls the pulsator of the washing machine to operate at the first preset rotation/stop ratio for the second preset time period so that the laundry can be sufficiently contacted with water. It should be noted that, preferably, the first rotation-stop ratio is that the impeller rotates at the washing speed for 0.6 second, and then stops rotating for 0.6 second; in the first vibration correction mode and the second vibration correction mode, the second preset time period is preferably 2 minutes. In step S107, the controller controls the pulsator of the washing machine to operate at the second preset rotation/stop ratio for the third preset time period so as to disperse the laundry as much as possible in the water to be uniformly distributed. It should be noted that, preferably, the second rotation/stop ratio is that the impeller rotates at the washing speed for 0.5 second, and then stops rotating for 0.5 second; in the first vibration correction mode and the second vibration correction mode, the third preset time period is preferably 1 minute. It will be understood by those skilled in the art that the specific time periods mentioned above are exemplary, and the skilled person can set the time periods according to actual use requirements. Finally, in step S108, the controller controls the washing machine to perform a water discharge operation so that the washing machine can continue to perform a dehydration operation in step S109.
Further, based on the above preferred embodiment, the control method further includes: when the frequency of the washing machine running vibration correction mode reaches the preset frequency, the washing machine can also send an abnormal prompt to a user. It can be understood that, after the washing machine operates the vibration correction mode for a plurality of times, if the washing machine still generates the phenomenon of continuous vibration, it means that the laundry entangled in the washing machine cannot be separated only by means of the vibration correction mode of the washing machine; therefore, the washing machine needs to send an abnormal prompt to a user, even prompts the user that the user needs to manually unwind the wound clothes, so that the user can accurately and efficiently solve the problem, and the safe operation of the washing machine is further ensured to the greatest extent. The skilled person in the art can understand that the skilled person can set the specific value of the preset times according to the actual use condition; preferably, the preset number of times is 4.
Finally, it should be noted that the above examples are all preferred embodiments of the present invention, and should not be construed as limiting the scope of the present invention. When the present invention is actually used, a part of the steps may be added or deleted as needed or the order between the different steps may be changed by those skilled in the art. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
So far, the preferred embodiments of the present invention have been described in conjunction with the accompanying drawings, but it is apparent to those skilled in the art that the scope of the present invention is 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.
