Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without any creative efforts shall fall within the protection scope of the embodiments of the present invention.
In the prior art, in the use process of the clothes dryer, because the weights of clothes are different, the required drying time is also different, and the clothes dryer can set the parameters of a drying program according to the weights of the clothes. The existing clothes dryer usually needs to be provided with a sensor for detecting weight in the clothes dryer so as to detect the weight of clothes, so that the cost of the clothes dryer is increased, the structure of the clothes dryer is complicated, and the stability of the clothes dryer is poor. Therefore, in the embodiment of the invention, the sensor for detecting the weight is not arranged in the clothes dryer, and the difference of the humidity data detected by the clothes with different weights in the clothes drying process is considered, and the humidity data has certain commonality, so the clothes weight is roughly judged according to the humidity data collected by the humidity sensor, and the clothes weight is classified, thereby the cost of the clothes dryer can be effectively reduced, the structure of the clothes dryer can be simplified, and the stability of the clothes dryer can be improved.
The dryer load weight acquiring process will be explained and explained in detail with reference to specific embodiments.
Fig. 1 is a flowchart of a method for acquiring a load weight of a clothes dryer according to an embodiment of the present invention. The embodiment provides a clothes dryer load weight obtaining method, which comprises the following specific steps:
s101, after a preset drying program is started, humidity data are collected in real time through a humidity sensor arranged in a clothes drying barrel.
In this embodiment, after the user puts the clothes to be dried into the clothes dryer, the preset drying program may be started for drying, optionally, the user may further select different clothes drying modes, for example, a sterilization mode, modes corresponding to different material types of the clothes, and the like, where the preset drying programs corresponding to different modes may be different.
In the embodiment, for the sake of cost and stability of the dryer, the dryer is not provided with a sensor for detecting weight, and the weight of the clothes in the dryer is obtained by using a humidity sensor, wherein the humidity sensor is arranged inside the dryer, preferably, the humidity sensor can be arranged in front of the drying barrel and below the opening of the drying barrel. After the preset drying program is started (for example, within a preset time after the preset drying program is started, such as within 2 minutes), the humidity data is collected in real time through the humidity sensor, and then grading can be carried out according to the weight of the clothes in the clothes drying barrel. Wherein the humidity data may include, but is not limited to, at least one of a laundry humidity value, a frequency at which the laundry contacts the humidity sensor, and a difference variation amount between adjacent humidity values.
S102, classifying the weight of the clothes in the clothes drying barrel according to the humidity data and a preset judgment rule to obtain the weight grade of the clothes.
In this embodiment, after the humidity data collected by the humidity sensor is obtained, the weight of the clothes in the clothes drying barrel can be classified according to the humidity data and the preset judgment rule.
Because the humidity data detected by the clothes with different weights in the clothes drying process are different and have a certain commonality, for example, the larger the weight of the clothes is, the larger the humidity value of the clothes collected by the humidity sensor is, wherein the humidity data collected by the humidity sensor may not be in contact with the clothes at all times, and therefore the humidity value of the clothes needs to be obtained by performing certain processing on the humidity data collected by the humidity sensor (for example, a filtering algorithm or a weighted average value is adopted, and the like, which is not described herein again); for another example, the larger the weight of the laundry, the more chance of contacting the humidity sensor, the more frequent the laundry contacts the humidity sensor, while the smaller the weight of the laundry, for example, the less chance of contacting the humidity sensor during the rotation of the clothes drying tub by one or two pieces of underwear and socks, the less frequent the laundry contacts the humidity sensor; for another example, the greater the weight of the laundry, the greater the chance of contacting the humidity sensor, the less the variation of the difference between the adjacent humidity values among the humidity values collected in real time by the humidity sensor changes, and the smaller the weight of the laundry, the greater the variation of the difference between the adjacent humidity values among the humidity values collected in real time by the humidity sensor, the less the chance of contacting the humidity sensor, changes. Therefore, in the present embodiment, based on the above-mentioned commonalities, the weight range of the laundry can be roughly determined from the humidity data, that is, the laundry weight can be classified to obtain the laundry weight grade.
In an optional embodiment, the classifying the weight of the laundry in the laundry drying tub according to the humidity data and a preset judgment rule to obtain a laundry weight grade may specifically include:
comparing the laundry humidity value with a preset humidity threshold value; and/or
Comparing the frequency of the clothes contacting the humidity sensor with a preset frequency threshold; and/or
Comparing the difference variation between the adjacent humidity values with a preset difference variation threshold;
determining a laundry weight grade according to the comparison result;
the clothes weight grades at least comprise two grades, wherein the clothes humidity value of the grade with larger clothes weight is larger, the frequency of the clothes contacting the humidity sensor is larger, and the difference change quantity between the adjacent humidity values is smaller.
In this embodiment, the weight of the laundry may be divided into at least two laundry weight levels in advance, and optionally, the weight of the laundry may be divided into three laundry weight levels, where the weight range of the small load level is 0.5 to 1.5 kg, the weight range of the medium load level is 1.5 to 4 kg, the weight range of the large load level is greater than 4 kg, each laundry weight level corresponds to different preset humidity thresholds, preset frequency thresholds, and preset difference variation thresholds, and the preset thresholds may be obtained in advance through a test or the like.
According to the method for acquiring the load weight of the clothes dryer, after the preset drying program is started, humidity data are acquired in real time through the humidity sensor arranged in the clothes drying barrel; and classifying the weight of the clothes in the clothes drying barrel according to the humidity data and a preset judgment rule to obtain the weight grade of the clothes. In the embodiment, the weight of the clothes is roughly judged according to the humidity data acquired by the humidity sensor, the weight of the clothes is classified, a sensor for detecting the weight is not required to be arranged in the clothes dryer, the cost of the clothes dryer can be effectively reduced, the structure of the clothes dryer can be simplified, and the stability of the clothes dryer is improved.
As a further improvement of the above embodiment, as shown in fig. 2, after the step of classifying the weight of the laundry in the laundry drying tub according to the humidity data and the preset judgment rule and obtaining the weight grade of the laundry in S102, the method may further include:
s201, adjusting the preset drying program according to the clothes weight grade, wherein at least one of the drying time length, the rotating mode of the clothes drying barrel and the drying ending humidity value of the preset drying program is adjusted.
In this embodiment, in order to ensure that the small-weight laundry is not excessively dried and the large-weight laundry is not completely dried, the preset drying program may be adjusted according to the obtained laundry weight level, wherein the adjusting of the preset drying program may include, but is not limited to, adjusting at least one of a drying time period, a laundry drum rotation manner, and a drying end humidity value of the preset drying program.
In an optional embodiment, the adjusting the preset drying program according to the weight grade of the laundry in S201 may specifically include:
for the grade with larger weight of the clothes, increasing the drying time, and/or controlling the clothes drying barrel to rotate in a positive and negative rotation mode after the preset drying time, and/or reducing the humidity value of the drying end; for a grade in which the weight of laundry is small, the drying time period is decreased, and/or the drying end humidity value is increased.
In this embodiment, for the clothes with a large weight, because the clothes cannot be unfolded in the clothes drying barrel, a winding phenomenon may occur, and a phenomenon that the clothes on the surface layer are dry and the clothes wrapped in the clothes are wet may also occur, so that the drying time period may be increased for the grade with a large weight, the clothes drying barrel may be controlled to rotate in a forward and reverse alternating manner after the predetermined drying time period, and the drying end humidity value may be reduced. For the clothes with smaller weight, the clothes can be unfolded in the clothes drying barrel, the longer drying time is not needed, the humidity value after drying is not too low, the excessive drying can be prevented, the forward and reverse rotation of the clothes drying barrel is not needed, and the drying efficiency can be improved.
As an example, for the above three laundry weight levels, the preset drying program may be adjusted as follows:
the small load grade (0.5-1.5 kg) is short in drying time on the basis of a preset drying program, the clothes drying barrel does not need to rotate in a positive and negative mode alternatively, the humidity value after drying is not too low, when the humidity value is up to the humidity value, clothes are dried uniformly, and the drying efficiency is high;
the drying time of the medium load grade (1.5-4 kg) is slightly longer on the basis of a preset drying program, the drying time can be within the range of 15-30 minutes, and the back section of the drying time needs to be that the clothes drying barrel rotates forward and backward alternately, and the back rotation is carried out once every 10-15 minutes; in addition, the humidity value of the drying end can be reduced;
the heavy load grade (more than 4 kg) needs longer drying time on the basis of a preset drying program, can be within the range of 30-60 minutes, the clothes drying barrel needs to rotate in a positive and negative rotation mode in the later period of drying, and the clothes drying barrel rotates in a positive and negative rotation mode once every 5-10 minutes, namely, the larger the weight of clothes is, the higher the positive and negative rotation frequency of the clothes drying barrel is, the winding can be effectively removed; in addition, the humidity value of the drying end can be reduced.
On the basis of the foregoing embodiment, optionally, the method further includes:
monitoring the variation of the humidity value of the clothes after the humidity value of the clothes reaches the drying end humidity value;
if the variation of the humidity value of the clothes in the preset time is smaller than a preset variation threshold, finishing drying;
if the variation of the humidity value of the clothes is not less than the preset variation threshold value in the preset time, the drying is continued according to the variation of the humidity value of the clothes.
In this embodiment, when the humidity value of the laundry reaches the humidity value at the end of drying, monitoring for a predetermined time may be performed again, and monitoring obtains a variation of the humidity value of the laundry, and if the variation of the humidity value of the laundry is smaller than a preset variation threshold value within the predetermined time, it is determined that the humidity value of the laundry has become stable, it is determined that the drying of the laundry is completed, and then the drying may be ended; if the variation of the humidity value of the clothes is not less than the preset variation threshold value within the preset time, it is indicated that only the surface layer clothes are dry and the clothes wrapped in the clothes are still wet, and the clothes wrapped in the clothes can permeate moisture to the outside, so that the humidity rises again, and the drying can be continued until the variation of the humidity value of the clothes is less than the preset variation threshold value, and the drying is finished. In an alternative embodiment, cold air can be introduced into the clothes drying barrel when drying is finished, so that the temperature of the clothes is reduced.
On the basis of any one of the above embodiments, in step S101, after humidity data is collected in real time by a humidity sensor arranged in the clothes drying barrel, empty barrel judgment can be performed, so as to avoid that the clothes drying machine operates in an empty barrel due to mistaken touch of a clothes drying machine switch, which causes waste of energy consumption, damage to the clothes drying machine, and the like. Specifically, as shown in fig. 3, the empty bucket determining process is as follows: comparing the humidity value acquired by the humidity sensor with a preset empty barrel humidity threshold (for example, the empty barrel humidity threshold is 200% rh), that is, performing S301 to determine whether the humidity value acquired by the humidity sensor is lower than the preset empty barrel humidity threshold; if the humidity value of the humidity sensor is lower than a preset empty barrel humidity threshold value, determining that no clothes are placed in the clothes drying barrel, and ending the preset drying program; if the humidity data is not lower than the preset empty barrel humidity threshold value, it is determined that the clothes are placed in the clothes drying barrel, and the method flow in the above embodiment can be continued.
