Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
In the related art, the laundry treating apparatus often determines whether defoaming is required in the dehydration stage based on an operation current of the dehydration motor or a torque value of the dehydration motor.
The embodiment of the invention provides a novel foam detection method of clothes treatment equipment, which can detect foam in a dehydration barrel in the dehydration stage of the clothes treatment equipment. The laundry treating apparatus may be a washing machine, a washing and drying all-in-one machine having a drying function, or a dehydrator for dehydrating laundry alone. The laundry treating apparatus includes: a dewatering barrel for dewatering clothes and a driving motor for driving the dewatering barrel to rotate. Here, the dehydration barrel may be separately provided, or the dehydration barrel may be a barrel body having a washing function, that is, the same barrel body as the washing barrel. In some embodiments, the driving motor may be driven by a frequency converter, and the frequency converter adjusts the rotation speed of the driving motor by controlling the voltage and frequency of the output power source, so as to drive the dewatering tub to rotate.
As shown in fig. 1, a method for detecting bubbles in a laundry machine according to an embodiment of the present invention includes:
Here, if there are more bubbles in the dehydration tub of the laundry treating apparatus during the dehydration stage, a certain amount of detergent and water may remain in the dehydration tub, thereby increasing the damping of the dehydration tub, resulting in an increase in the acceleration time required for the dehydration acceleration stage. Therefore, the excessive foam in the dewatering barrel can be judged if the acceleration duration is greater than or equal to the duration reference value by acquiring the acceleration duration of the dewatering acceleration stage and comparing the acceleration duration with the duration reference value. It can be understood that the reference value of the time length can be reasonably determined based on experiments to be used as a basis for judging whether the foam in the dewatering barrel is excessive or not.
According to the embodiment of the invention, based on the acceleration duration of at least one dehydration acceleration stage in the dehydration stage of the clothes treatment equipment, the foam in the dehydration barrel of the clothes treatment equipment is detected, so that the detection of the foam in the dehydration barrel can be realized, the clothes treatment equipment can be controlled to perform defoaming treatment when the foam in the dehydration barrel is excessive, the dehydration reliability is prevented from being influenced by dehydration with water, and the influence of foam overflow on the clothes treatment equipment can be effectively prevented
In some embodiments, the dehydration phase of the laundry treatment apparatus comprises: the dewatering device comprises a first dewatering acceleration stage, a first dewatering maintenance stage, a second dewatering acceleration stage and a second dewatering maintenance stage, wherein the driving motor drives the dewatering barrel to climb to a first dewatering rotating speed from an initial rotating speed, the driving motor drives the dewatering barrel to continuously run at the first dewatering rotating speed, the driving motor drives the dewatering barrel to climb to the second dewatering rotating speed from the first dewatering rotating speed, and the driving motor drives the dewatering barrel to continuously run at the second dewatering rotating speed. Wherein, the first dehydration rotating speed and the second dehydration rotating speed can be set according to the actual situation. For example, the first dehydration rotation speed may be 400rpm (revolutions per minute) and the second dehydration rotation speed may be 600rpm. The initial rotation speed may be zero or may be a lower initial rotation speed, for example, the initial rotation speed may be 90rpm. Illustratively, the first dehydration acceleration phase is a rotation speed increasing phase that the driving motor drives the dehydration barrel to climb from 90rpm to 400rpm, and the second dehydration acceleration phase is a rotation speed increasing phase that the driving motor drives the dehydration barrel to climb from 400rpm to 600rpm. Accordingly, the duration reference value includes: a first duration reference value corresponding to the first dehydration acceleration stage and a second duration reference value corresponding to the second dehydration acceleration stage.
In some embodiments, for the first dehydration acceleration stage, the detecting of bubbles in the dehydration tub of the laundry treating apparatus based on the acceleration duration of at least one of the dehydration acceleration stages of the laundry treating apparatus includes:
acquiring a first acceleration duration corresponding to a first dehydration acceleration stage of the laundry treatment apparatus;
and determining that the first acceleration time length is greater than or equal to a first time length reference value, and judging that excessive foam is generated in the dewatering barrel.
In some embodiments, for the second dehydration acceleration stage, the detecting of bubbles in the dehydration tub of the laundry treating apparatus based on the acceleration duration of at least one of the dehydration acceleration stages of the laundry treating apparatus includes:
acquiring a second acceleration duration corresponding to a second dehydration acceleration stage of the clothes treatment equipment;
and determining that the second acceleration time length is greater than or equal to a second time length reference value, and judging that excessive foam is generated in the dewatering barrel.
Here, the clothes treatment apparatus often has many times of dehydration acceleration in the dehydration process, and if the excessive foam in the dehydration barrel cannot be detected in time in the subsequent dehydration acceleration stage, the operation reliability of the clothes treatment apparatus in the high-speed dehydration stage is often affected, that is, there are risks of barrel collision and the like of the dehydration barrel caused by dehydration with water, and also there is a risk of foam overflow. Based on this, the laundry treatment apparatus of the embodiment of the present invention determines whether the bubbles in the spin-drying tub are excessive based on the comparison result of the first acceleration duration and the first duration reference value, not only for the first dehydration acceleration stage; and also for the second dehydration acceleration stage, judging whether the foam in the dehydration barrel is excessive or not based on the comparison result of the second acceleration duration and the second duration reference value. It is understood that if the laundry treating apparatus further has a dehydration acceleration stage climbing from the second dehydration rotation speed to a higher dehydration rotation speed, a corresponding time duration reference value may be further set, and whether the bubbles in the dehydration tub are excessive may be determined based on a result of comparing the acceleration time duration of the corresponding dehydration acceleration stage with the corresponding time duration reference value. Therefore, the foam in the dewatering barrel can be detected in different operation stages of the clothes treatment equipment in the dewatering process.
It is understood that the foam detection method according to the embodiment of the present invention may be performed by a controller (e.g., a main control board of a computer of a washing machine) of a laundry treatment apparatus, and the controller may receive the rotation speed of the spin-drying tub detected by the speed sensor in real time, so as to determine a first acceleration duration of the first spin-drying acceleration stage and a second acceleration duration of the second spin-drying acceleration stage. The first duration reference value and the second duration reference value may be calibrated through experiments. Exemplarily, the first dehydration acceleration stage corresponds to a rotation speed increasing stage of the dehydration barrel from 90rpm to 400rpm, and the value range of the first time length reference value is 35 to 40 seconds; the second dehydration acceleration stage corresponds to a rotation speed climbing stage of the dehydration barrel from 400rpm to 600rpm, and the value range of the second duration reference value is 27-30 seconds.
In practical application, because the types of the driving motors of the clothes treatment equipment are more, the setting of the first time length reference value and/or the second time length reference value is difficult to meet the detection requirements of different driving motors, and the detection result of the foam in the dehydration barrel is unreliable. Based on this, in some embodiments, the driving motor is driven by a frequency converter, and the foam detection method of embodiments of the present invention further includes:
determining the first time period reference value based on an acceleration step size of a frequency converter of the laundry treating apparatus in the first dehydration acceleration stage.
Here, the acceleration step may be understood as an increment of the rotation speed of the dehydration tub per unit time, for example, the acceleration step may be an increment of the rotation speed of the inverter-driven dehydration tub per unit time which is set by default, and thus, the first time period reference value may be determined based on the acceleration step and a difference between the first dehydration rotation speed of the first dehydration acceleration stage and the initial rotation speed (i.e., an increment of the rotation speed of the first dehydration acceleration stage). Therefore, the calibration process of the first time length reference value can be omitted, the precision of the first time length reference value can be improved, and the reliability of the detection result of the foam in the dewatering barrel is improved.
In some embodiments, the foam method of embodiments of the present invention further comprises:
determining the second duration reference value based on an acceleration step size of a frequency converter of the laundry treating apparatus in the second dehydration acceleration stage.
Similarly, the second duration reference value may be determined according to the acceleration step of the second dehydration acceleration stage and the difference between the second dehydration rotation speed of the second dehydration acceleration stage and the first dehydration rotation speed (i.e. the rotation speed increment of the second dehydration acceleration stage). Therefore, the calibration process of the second duration reference value can be omitted, the precision of the second duration reference value can be improved, and the reliability of the detection result of the foam in the dewatering barrel is improved.
In order to reduce the consumption of computational resources of the controller of the laundry treatment apparatus, in some embodiments, the foam detection method of embodiments of the present invention is performed by a frequency converter of the laundry treatment apparatus. Therefore, the resource consumption of the controller can be reduced, and the frequency converter independently realizes the detection of the foam in the dehydration barrel. Specifically, the frequency converter can receive a dehydration instruction sent by the controller, and the frequency converter controls the dehydration barrel to operate in a first dehydration acceleration stage, a first dehydration maintenance stage, a second dehydration acceleration stage and a second dehydration maintenance stage based on the dehydration instruction. The frequency converter can determine a first time length reference value based on the acceleration step length of the first dehydration acceleration stage and the rotation speed increment of the dehydration barrel in the first dehydration acceleration stage, and can also acquire the first acceleration time length based on the rotation speed of the dehydration barrel fed back by the speed sensor, so that whether the foam in the dehydration barrel is excessive or not is determined according to the comparison result of the first acceleration time length and the first time length reference value. Accordingly, the frequency converter may determine the second duration reference value based on the acceleration step of the second dehydration acceleration stage and the rotation speed increment of the dehydration barrel in the second dehydration acceleration stage, and the frequency converter may further acquire the second acceleration duration based on the rotation speed of the dehydration barrel fed back by the speed sensor, so as to determine whether the foam in the dehydration barrel is excessive according to the comparison result of the second acceleration duration and the second duration reference value.
In some embodiments, the frequency converter determines that the foam in the dehydration barrel is excessive, and sends a prompt message indicating the foam removal to a controller of the clothes treatment apparatus; the controller controls the clothes treatment device to perform defoaming treatment based on the prompt information. So, the converter can in time send the suggestion information and give the controller when monitoring that there is too much the condition of foam in the dehydration bucket, and the controller of being convenient for in time controls clothing treatment facility and carries out the defoaming and handle.
In some embodiments, the controller controls the laundry treating apparatus to perform the bubble removing treatment based on the prompt information, including:
responding to the prompt information, and acquiring the water level in the dewatering barrel;
and determining that the water level is higher than a preset water level threshold value, and controlling the clothes treatment equipment to perform defoaming treatment.
Here, in order to prevent the misinformation of the prompt information, the controller can also acquire the water level in the dehydration barrel detected by the liquid level sensor, determine that the water level is higher than a preset water level threshold value, and then control the clothes treatment equipment to perform defoaming treatment, so that the accuracy of the clothes treatment equipment entering the defoaming treatment is improved. The preset water level threshold may be determined through experimentation.
In order to implement the method of the embodiment of the present invention, the embodiment of the present invention further provides a foam detection device of a clothes treatment apparatus, the foam detection device of the clothes treatment apparatus corresponds to the method for controlling the clothes treatment apparatus, and the steps in the method for controlling the clothes treatment apparatus are also fully applicable to the embodiment of the foam detection device of the clothes treatment apparatus.
