The following provides a detailed description of the spin-drying control method of the washing machine according to the present invention with reference to the specific embodiments.
Fig. 1 schematically shows a structural view of a washing machine.
As shown in fig. 1, the washing machine includes at least a cabinet 10, a dehydration tub 20, a motor driving device 30, a door 40, and a drain pump 50. Wherein the dehydration tub 20 includes an outer tub and an inner tub rotatably fixed in the outer tub. The door 40 is pivotably provided on the cabinet 10 for opening or closing the inner tub.
In the dehydration process, a controller of the washing machine sends a dehydration command to the motor driving device 30, the motor driving device 30 drives the motor to drive the inner barrel to rotate, the inner barrel is provided with small holes which are distributed at intervals, when the inner barrel rotates, clothes in the inner barrel generate centrifugal force, and moisture in the clothes is thrown out of the small holes of the inner barrel under the action of the centrifugal force, so that the clothes are dehydrated.
Fig. 2 is a flowchart of a dehydration control method of a washing machine according to an embodiment of the present application. The control method is specifically performed by a controller of the washing machine, and in this embodiment, the washing machine dehydration method includes at least the following steps S210 to S240.
Step S210, determining the highest dehydration speed of the washing machine according to the load parameter in the dehydration barrel.
In one embodiment, the load parameters include load amount and eccentricity amount. The loading amount of the inner tub is a loading amount of a driving device of the washing machine. The loading capacity can be the weight of the object to be dehydrated and the contained moisture in the inner barrel. The eccentricity is the eccentric mass due to uneven load distribution. It is easily understood that the amount of load, eccentricity and the magnitude of the dewatering noise are generally proportional. Specifically, the larger the weight of the object to be dehydrated and the moisture contained therein, the larger the amount of load, and in the case of the larger amount of load, the larger the dehydration noise will be generated. The larger the eccentricity is, the larger the noise at the same rotation speed is. Generally, the gap between the dehydration tub and the washing machine cabinet is fixed, and in order to prevent the dehydration tub from hitting the cabinet, the load amount and the eccentricity amount limit the rotation speed of the dehydration tub, and thus, according to the load amount and the eccentricity amount, the maximum dehydration rotation speed of the washing machine can be determined.
In another embodiment, the load parameter may further include a material of the clothes, illustratively, the cotton clothes is easy to absorb water, in order to ensure the dehydration effect, a higher maximum dehydration rotation speed may be set for dehydration, and the silk material is easy to damage, in order to not damage the clothes, save energy and reduce noise, a lower maximum dehydration rotation speed may be set for dehydration.
And S220, acquiring state parameters, wherein the state parameters comprise airing environment parameters and/or user parameters in a room where the washing machine is located.
Wherein the drying environment parameter is the drying environment of the dehydrated clothes. The airing environment parameter may include at least one of the airing environment temperature, a heat radiation degree parameter, and a wind speed. It is easy to understand that if the airing environment is a high-temperature and ventilated environment, the maximum dehydration speed can be reduced by a certain amount, so that the energy consumption and the dehydration noise can be reduced on the basis of not influencing the clothes drying effect.
Finally, the dewatering noise of the washing machine is reduced to reduce interference to users, and therefore, in the embodiment, user parameters in a room where the washing machine is located can be obtained to determine whether to reduce the dewatering parameters according to the user parameters. In one embodiment, the mechanical vibration sound and the sound of the user activity can be distinguished through the sound sensor, and the number of the users who are active in the room can be obtained in real time according to the sound of the user activity. In one embodiment, typically, when the user is in a room, the connection will be through a local area communication means such as wifi. Therefore, the number of users in the room can be determined according to the number of users connected by the local area communication method. In another embodiment, an equipment management platform can be installed on an intelligent terminal of a user, the equipment management platform is used for managing intelligent equipment such as a washing machine, and the user can selectively set dehydration noise through the equipment management platform, so that the dehydration rotating speed can be managed according to the independent desire of the user.
And step S230, determining the rotating speed reduction amount based on the highest dehydration rotating speed based on the state parameters.
As mentioned before, the status parameters include the airing environment parameters and/or the user parameters in the room where the washing machine is located.
Illustratively, if the user has a greater tolerance for noise, the amount of reduction in rotational speed may be set to zero; if the drying environment is an environment with larger heat radiation, the rotating speed reduction can take a larger value, and if the drying environment is an environment with better ventilation condition, the rotating speed reduction can also take a larger value, in other words, the dehydration rotating speed is adjusted according to the drying environment parameters and/or the user parameters in the room where the washing machine is located.
And step S240, calculating a target dehydration rotating speed according to the highest dehydration rotating speed and the rotating speed reduction amount so as to perform dehydration through the target dehydration rotating speed.
The target spinning speed is easily obtained from the maximum spinning speed and the reduced amount of the spinning speed. It should be noted that the washing machine usually has a uniform distribution stage, a shaking stage and a high-speed dewatering stage when dewatering. The target dehydration rotating speed is the maximum rotating speed in a high-speed dehydration stage, and can also be the maximum rotating speed in each stage such as an even distribution stage, a shaking and dispersing stage, a high-speed dehydration stage and the like.
Therefore, in the application, the maximum dehydration rotating speed is determined according to the load parameters, the generation of noise such as barrel collision is guaranteed, the dehydration safety can be guaranteed, and then the target dehydration rotating speed of the dehydration barrel is matched with the air-drying environment parameters and/or the user parameters in the room where the washing machine is located, on one hand, the dehydration rotating speed can be adjusted in real time according to the natural clothes drying effect of the air-drying environment, the energy conservation and the noise reduction are realized, on the other hand, the dehydration rotating speed can be adjusted in real time according to the user condition, and therefore the energy conservation and the noise reduction are realized under the condition that the user experience is guaranteed.
In one embodiment, the washing machine may have an intelligent communication unit for establishing a connection relationship with an intelligent terminal of a user to acquire the state parameters through the connection relationship. Specifically, the intelligent communication unit may be connected to an external network, and establish a connection with an intelligent terminal of a user based on the external network, thereby implementing communication. The intelligent terminal can be a portable device such as a user mobile phone and a tablet personal computer. It is easy to understand that the mobile phone can be provided with an intelligent management platform, a user can obtain environmental parameters such as weather and wind speed through the intelligent management platform, and can also input air-drying environmental parameters, schematically, the user can input information such as ' air-drying environment is indoor with warm air, indoor temperature is 22 ℃, and ' no person is in the room during washing and dehydration ', so that the intelligent management platform obtains the air-drying environmental parameters and/or the user parameters, the intelligent management platform can calculate the dehydration parameters according to the obtained parameters, and can also send the obtained parameters to the washing machine, and the washing machine calculates and obtains the dehydration parameters such as rotating speed, and therefore, the air-drying environmental parameters and/or the user parameters can be conveniently and reliably obtained.
Fig. 3 is a flowchart of a dehydration control method of a washing machine according to another embodiment of the present application. As shown in fig. 3, in this embodiment, the user parameter includes a static user parameter, and the rotation speed reduction based on the maximum dehydration rotation speed is determined based on the state parameter, which may specifically include the following steps:
step S310, at least one static user parameter of the age, the sex, the work and rest time and the dehydration habit of the user is obtained.
Step S320, determining the dehydration noise tolerance of the user according to the obtained static user parameters;
and step S330, determining the rotating speed reduction amount on the basis of the highest dehydration rotating speed according to the dehydration noise tolerance degree.
Specifically, at least one static user parameter of the age, sex, work and rest time and the dehydration habit of the user can be obtained according to the information of the registered management user of the washing machine on the intelligent management platform running on the intelligent terminal of the user. The registration management user may be one or more, and thus, static user information is available.
After obtaining the static user parameters, the dehydration noise tolerance of the user may be determined. Specifically, the tolerance degree of users in all ages, male users and female users, users with regular work and rest time and users with disordered work and rest time to noise can be obtained according to big data. In addition, the dehydration habit of a specific user can be acquired during long-term use. According to the information, the tolerance level of the dehydration noise of the specific user corresponding to the washing machine can be obtained, and then the dehydration rotating speed is generated according to the tolerance level of the dehydration noise, so that under the condition of ensuring the experience of the user, energy conservation and noise reduction are realized.
Further, in one embodiment, the user parameters also include dynamic user parameters.
The method for determining the rotating speed reduction amount based on the highest dehydration rotating speed based on the state parameter specifically comprises the following steps: acquiring the dynamic user parameters in real time, wherein the dynamic user parameters comprise the number of real-time users in a room where the washing machine is located; and under the condition that the number of the real-time users is zero, determining that the rotating speed reduction amount is zero, and dehydrating at the highest dehydration rotating speed.
It should be noted that the dynamic user parameters characterize real-time user parameters, which have a higher priority than the static user parameters. Illustratively, under the condition that the number of the real-time users is zero, the rotating speed reduction amount is determined to be zero, so that the quick dehydration can be realized under the condition of no influence on the users. In another embodiment, if the number of real-time users is not zero, but if the on-site users are noise insensitive, the same maximum spin rate can be used for spinning.
In order to further realize the energy conservation and noise reduction under the condition of ensuring the experience of the user. In one embodiment, the washing machine dehydration control method may further include at least the steps of:
according to the state parameters, generating and sending dehydration suggestions corresponding to the state parameters to a user;
and determining the rotation speed reduction amount on the basis of the highest dehydration rotation speed on the basis of the state parameter under the condition that the user agrees to the dehydration suggestion.
Illustratively, after the drying parameters, the user parameters, the season parameters, the weather parameters and other state parameters are obtained, the dewatering advice corresponding to the state parameters can be sent to the user.
Specifically, in order to fully guarantee the right of the user for independent selection, the related dehydration suggestion can be generated and sent to the intelligent terminal of the user, the adoption result of the user for the dehydration suggestion is received, and then the dehydration rotating speed of the washing machine can be determined according to the adoption result.
In one embodiment, the method for controlling dehydration of a washing machine may further include the steps of: monitoring the dehydration noise of the dehydration barrel in the dehydration process; and when the dewatering noise is greater than a set threshold value, controlling the dewatering barrel to reduce the speed for dewatering.
Specifically, in the dewatering process, a noise upper limit value can be set, a dewatering real-time noise value is obtained through the sound sensor, the dewatering real-time noise value is compared with the noise upper limit value, if the dewatering real-time noise value is larger than the noise upper limit value, the rotating speed of the dewatering barrel is reduced to the rotating speed corresponding to the next gear, the situation that the noise is too high is prevented, the rotating speed of the dewatering barrel can be gradually reduced until the dewatering real-time noise value is reduced to be lower than the noise upper limit value, therefore, the situation that the noise is too high is prevented, and the dewatering safety is guaranteed.
In one embodiment, the sunning environmental parameter includes at least one of a sunning environmental temperature, a degree of heat radiation, and a wind speed. If any one of the airing environment temperature, the heat radiation degree and the wind speed meets a preset speed reduction dehydration condition, reducing a second rotation speed amount on the basis of the highest dehydration rotation speed; and dewatering is performed based on the reduced rotation speed to reduce dewatering noise.
Specifically, sunning ambient temperature, thermal radiation degree parameter and wind speed are the representative parameter of representation sunning ambient parameter, and when sunning ambient temperature, thermal radiation degree parameter and wind speed any one of them reach and predetermine the speed reduction dehydration condition, can be at the reduction second rotational speed volume on the basis of the highest dehydration rotational speed, dewater with lower rotational speed. Therefore, the dewatering rotating speed can be adjusted in real time according to the natural clothes drying effect of the airing environment.
Fig. 4 is a flowchart of a dehydration control method of a washing machine according to another embodiment of the present application. As shown in fig. 4, in this embodiment, the acquiring of the state parameters includes acquiring the drying parameters after dehydration, the season parameters, and the weather parameters. The method for determining the rotating speed reduction amount based on the highest dehydration rotating speed based on the state parameters specifically comprises the following steps:
and S410, if any one of the drying parameters, the seasonal parameters and the weather parameters meets the preset high-speed dehydration condition, determining that the reduction of the rotating speed is zero, and dehydrating at the highest dehydration rotating speed.
Specifically, if any one of the drying parameter, the seasonal parameter and the weather parameter meets a preset high-speed dehydration condition, the rotation speed reduction is determined to be zero, and dehydration is performed at the highest dehydration rotation speed. In this embodiment, the status parameters include a drying parameter after dehydration, a season parameter, and a weather parameter. And if any one of the drying parameters, the seasonal parameters and the weather parameters meets the preset high-speed dehydration condition, determining that the reduction of the rotating speed is zero, and dehydrating at the highest dehydration rotating speed. Specifically, the preset high-speed dehydration conditions corresponding to the drying parameters, the seasonal parameters and the weather parameters can be preset, so that the speed reduction treatment is not carried out under special conditions, and the dehydration effect is preferentially ensured. The drying parameters are used for representing whether drying operation is carried out after dehydration. Illustratively, if the drying parameter is 1, drying is performed, in which case the deceleration process may not be performed, and the load may be put into the drying process in a state where the moisture content is low. In winter, the heat radiation in the airing environment is usually less, so that in winter, the speed reduction treatment is not needed, the load is aired in a state of low water content, and the clothes drying effect is ensured. The weather parameters are used for indicating cloudy days, sunny days or rainy days, and the speed reduction treatment can be omitted under the condition that the weather parameters are in cloudy days or rainy days, so that the load is aired in a state with low water content, and the clothes drying effect is ensured.
Further, in an embodiment, determining the rotation speed reduction amount based on the maximum dehydration rotation speed based on the state parameter may further include the steps of:
step S420, acquiring time interval parameters, temperature parameters and age parameters of a user in a room where the washing machine is located;
and step S430, if any one of the time interval parameter, the temperature parameter and the age parameter meets a preset speed reduction dehydration condition, reducing a first rotation speed amount on the basis of the highest dehydration rotation speed.
In particular, this step is specifically considered from the user parameter point of view. Wherein. The time period parameter is used to indicate whether it is morning, afternoon or evening. Because the user usually has a rest at night, the tolerance of the user to the noise is low, and therefore if the time period parameter indicates that the user is at night, the time period parameter meets the preset deceleration dehydration condition. The temperature parameter is indicative of a real-time temperature in a room in which the washing machine is located. If the temperature is lower or higher and is out of the comfortable temperature sensed by the user, the tolerance degree of the user to the dehydration noise is lower, so that when the temperature parameter is out of the set range, the temperature parameter can be determined to meet the preset deceleration dehydration condition. In addition, if the user is older, the user is usually more sensitive to sound, so when the user is older than the preset age, the age parameter conforms to the preset deceleration dehydration condition. And when any one of the time period parameter, the temperature parameter and the age parameter meets a preset speed reduction dehydration condition, reducing the first rotation speed amount on the basis of the highest dehydration rotation speed, and performing dehydration by using a lower rotation speed.
From this, can simplify the control process, can carry out real-time adjustment to the dehydration rotational speed according to the nature dry clothing effect of sunning environment on the one hand, realize energy-conservation and fall and make an uproar, on the other hand can also adjust the dehydration rotational speed according to the user's condition in real time to under the condition of guaranteeing user experience and feeling, realize energy-conservation and fall and make an uproar.

step S503, if any one of the total load mass M and the eccentricity N is less than or equal to the corresponding threshold value, the clearance between the dewatering barrel and the box body is obtained in real time in the rotating process of the barrel;
step S504, judge whether the clearance is less than or equal to the preset clearance threshold value P, if less than or equal to, carry out step S507, dehydrate with the lower dehydration rotational speed; if yes, go to step S505;
step S505, judging whether drying is needed after dehydration, whether the drying is in winter or not and whether the drying is in cloudy days or not, if any one of the drying, the drying and the drying meets the preset high-speed dehydration condition, executing step S508, and dehydrating at a higher rotating speed;
step S506, judging whether the temperature is at night, whether the temperature is high indoors or not and whether the old people are at home or not, if any one of the three meets the preset speed reduction dehydration condition, executing step S507, and dehydrating at a lower dehydration rotating speed;
step S507, dehydrating at a second rotating speed, wherein the second rotating speed is less than the first rotating speed;
and step S508, dewatering at the first rotating speed.

In this embodiment, the washing machine is provided with a mass threshold M0 and an eccentricity threshold N0, and if any one of the total mass M and the eccentricity N of the load exceeds the corresponding threshold, the washing machine performs spin-drying at a lower rotation speed.
The box body clearance is used for monitoring the distance between the dewatering barrel and the box body so as to prevent the barrel from impacting the box body, if the monitored box body clearance is smaller than a preset clearance threshold value P, the clearance value is too small, the eccentric centrifugal force is large, and the lower rotating speed can be used for dewatering.
If the monitored box body clearance is larger than or equal to the preset clearance threshold value P, acquiring the state parameters of whether drying is needed after dehydration, whether the drying is in winter and whether the drying is in cloudy days, and dehydrating at a high rotating speed if any one of the three meets the preset high-speed dehydration condition so that the water content of the clothes after dehydration is less and the clothes are convenient to be dried or aired.
If the drying is needed, whether the drying is in winter and whether the drying is in cloudy days, if the drying, the drying and the dehydrating are not in accordance with the preset high-speed dehydrating condition, whether the drying is in the evening, whether the indoor temperature is high, and whether the old people are at home are judged, if any one of the drying, the indoor temperature is high, and the old people are at home are in accordance with the preset speed reduction dehydrating condition, the dehydrating is carried out at a lower rotating speed, otherwise, the dehydrating is carried out at a higher rotating speed. In this embodiment, the lower rotation speed is the second rotation speed, the second rotation speed can be configured to be any one of 1000-.
From this, can simplify the control process, can carry out real-time adjustment to the dehydration rotational speed according to the nature dry clothing effect of sunning environment on the one hand, realize energy-conservation and fall and make an uproar, on the other hand can also adjust the dehydration rotational speed according to the user's condition in real time to under the condition of guaranteeing user experience and feeling, realize energy-conservation and fall and make an uproar.
