Detailed Description
The technical solutions of the present invention will be clearly and completely described in connection with the embodiments, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1, an embodiment of the present invention provides a drying control method, including:
s101, supplying power to a heating structure for heating the wall of a drying roller according to initial power;
s102, collecting temperature values of at least one temperature sensor on the drying roller in real time, wherein the temperature sensor is used for detecting the roller wall temperature of the drying roller;
s103, analyzing and judging the temperature values acquired in real time, or analyzing and judging the temperature values acquired in real time in a first preset time every interval after processing:
if the drying roller is judged to be in a cooling stage according to the temperature value acquired in real time or the value obtained after the treatment, controlling to continuously supply power to the heating structure according to the initial power;
if the drying roller is in a heating stage according to the temperature value acquired in real time or the value obtained after the treatment, determining a power value corresponding to the temperature value acquired in real time or the value obtained after the treatment according to the corresponding relation between the preset temperature value or the value obtained after the treatment and the power value, controlling the power supply of the heating structure according to the power value, and setting the power value in a decreasing trend in the heating stage;
if the drying roller is judged to enter a temperature constant state according to the temperature value acquired in real time or the processed temperature value, the heating structure is controlled to stop being powered according to the ending power for a second preset time or the heating structure is directly controlled to stop being powered.
By executing S101, when the drying drum is started up, the heating structure for heating the drum wall of the drying drum is controlled to supply power according to the initial power, and the drying drum is rapidly heated.
Since there is a certain relationship between the humidity of the object to be dried (e.g., wet laundry) and the temperature of the drying drum, by executing S102, the temperature of a certain place fixed on the drying drum or a certain place is monitored in real time as data for analyzing the drying condition of the object to be dried (e.g., wet laundry) in the drying drum in real time, so as to control the drying power and the drying time according to the drying condition.
When the drying drum is in contact with the wall of the heated drying drum in the rotating process, the lower-temperature dried object (such as wet clothes) can take away the heat of the contact part of the wall, so that the temperature of the contact part of the wall can be reduced, and therefore, in the initial operation stage of the drying drum, the temperature value fed back by the temperature sensor on the drying drum can be in a cooling stage. That is, when this cooling stage is detected, the humidity of the object to be dried (e.g., wet laundry) is relatively high, and the heating structure needs to be powered with a relatively high initial power to improve the drying efficiency.
Along with the lapse of drying time, the moisture on the dried object (such as wet clothes) is less and less, and the heat of the drum wall is taken away, so that the drying drum has a heating stage after the cooling stage, and the drum wall temperature is higher and higher because the moisture on the dried object (such as wet clothes) is less and less, the heating structure is not required to be powered by larger initial power, therefore, the power can be correspondingly regulated according to the heating condition in the heating stage, and the effect of energy conservation can be realized while the clothes can be dried rapidly.
When the drying enters the tail sound, the moisture on the dried object (such as wet clothes) is completely dried, and the dried object (such as wet clothes) does not take away the heat of the cylinder wall any more, so that the drying cylinder can have a constant temperature state after the temperature rising stage, at the moment, the dried object (such as wet clothes) is dried, and the heating structure is controlled to stop after the second preset time of power supply according to the end power. By executing S103, the real-time temperature collected at a certain place fixed on the drying drum is analyzed and judged, or the real-time temperature collected at a certain place fixed on the drying drum is analyzed after being processed, so that the current stage of the drying drum is judged, and the power for supplying power to the heating structure is correspondingly adjusted. And the power supply of the heating structure is regulated according to the drying degree of clothes at each stage, so that the energy-saving effect can be achieved while the clothes are dried rapidly.
The following description will be made by taking an example of analyzing and judging temperature values collected in real time by collecting temperature values on at least two temperature sensors on the drying drum in real time.
As shown in fig. 2, temperature values of at least two temperature sensors on the drying drum are collected in real time, and analysis and judgment are performed on the temperature values collected in real time.
At least two positions are temperature sensors which can be arranged to collect two positions on the drying roller in real time, and temperature values on three positions or four positions or five positions and other temperature sensors can also be arranged to collect the temperature values on the three positions or five positions in real time, but as a preferable mode, the temperature values of the three temperature sensors arranged on the drying roller are collected in real time to be optimal, the detection is more accurate, and the three temperature sensors are further preferable to be uniformly distributed on the drying roller.
S201, if at least one of temperature values fed back by all temperature sensors acquired in real time is within a first preset threshold range, controlling to continuously supply power to the heating structure according to initial power.
S202, if all temperature values fed back by all temperature sensors collected in real time are higher than the highest value in the first preset threshold range, judging that the drying roller is in a heating stage, determining a power value corresponding to a temperature average value collected by all the temperature sensors in real time by comparing with the corresponding relation between the preset temperature values and the power values, controlling the power to supply power to the heating structure according to the power value, and in the heating stage, the power values are in a decreasing trend.
And S203, if the temperature values fed back by all the temperature sensors acquired in real time are unchanged, judging that the drying roller enters a temperature constant state, and controlling to stop supplying power to the heating structure according to the second preset time after the power supply of the heating structure is finished or directly controlling to stop supplying power to the heating structure.
In S201, the first preset threshold range may be designed according to experimental data, for example, set to be in a range of 58 ℃ to 62 ℃, and since the heating structure is powered according to the initial power when the drying drum is started up, the initial power is generally set to be full power, i.e. power is supplied according to the maximum power, for example 1700W, so that the drum wall temperature of the drying drum is higher, and when the object to be dried (such as wet clothes) contacts with the portion of the drying drum where the temperature sensor is provided, heat is taken away, thereby causing the data detected by the temperature sensor at the portion to be reduced; therefore, if only one temperature value is within the first preset threshold value range, the drying drum is proved to be in a cooling stage, and the humidity of the dried object (such as wet clothes) is high, so that the power supply needs to be continued according to the initial power.
In S202, if the temperature values fed back by all the temperature sensors collected in real time are higher than the highest value in the first preset threshold range, it is proved that the moisture of the dried object (such as wet clothes) is decreasing, and the heat on the drum wall is reduced, so as to determine that the drying drum is in the temperature raising stage. The water content of the dried object (such as wet clothes) is reduced, power supply is not needed according to initial power, the power value corresponding to the temperature average value acquired by all temperature sensors in real time can be determined according to the corresponding relation between the preset temperature value and the power value, the power supply to the heating structure according to the power value is controlled, the corresponding relation between the preset temperature value and the power value can be set according to experimental data, for example, when the average temperature value is about 70 ℃, the power value is 1500W; when the average temperature value is 75 ℃, the power value is 1300W, etc.
In S203, if the temperature values fed back by all the temperature sensors collected in real time are unchanged, it is proved that the moisture on the object to be dried (such as wet clothes) is already dried, and it is determined that the drying drum enters a constant temperature state, and at this time, the heating structure can be controlled to stop supplying power for a second preset time after the power supply is finished or the heating structure can be controlled to stop supplying power.
As shown in fig. 3, the following description will be given by taking an example of acquiring a temperature value on a temperature sensor at a position on the drying drum in real time, and analyzing and judging the temperature value acquired in real time in a first preset time every interval after processing.
S301, acquiring a temperature value of a temperature sensor on the drying roller in real time, selecting a preset number of temperature maximum values from the temperature values acquired in real time within a first preset time interval, calculating an average value t1 of the temperature maximum values, selecting a preset number of temperature minimum values, calculating an average value t2 of the temperature minimum values, and analyzing and judging the temperature difference value Deltat.
S302, if the temperature difference value delta t is within a second preset threshold range, judging that the temperature of the drying roller is continuously low, and controlling the drying roller to continuously dry according to the initial power.
S303, if the temperature difference value delta t is smaller than the lowest temperature value in the second preset threshold range, determining a power value corresponding to the temperature difference value delta t according to the corresponding relation between the preset temperature difference value and the power value, controlling the heating structure to be powered according to the power value, and setting the power value in a descending trend in the heating stage.
S304, if the temperature difference delta t is approximately equal to 0 and the third preset time is maintained, judging that the drying roller enters a temperature constant state, controlling the heating structure to stop supplying power according to the second preset time after the power supply of the heating structure is finished or directly controlling the heating structure to stop supplying power.
In S301, since the drying drum is not always in contact with the portion of the drum wall of the drum where the temperature sensor is disposed during rotation of the drying drum, the temperature value detected when the drying object (e.g., wet laundry) contacts the portion is low, and the temperature value detected when the drying object (e.g., wet laundry) does not contact the drum wall is high; therefore, in the first preset time every interval, the stage of the drying roller can be judged through the temperature difference value delta t between the average value t1 of the preset number of the highest temperature values and the average value t2 of the preset number of the lowest temperature values; the first preset time per interval may be set according to experimental data, such as 0.5 minutes per interval.
In S302, a second preset threshold range may be set according to experimental data, such as 38 ℃ to 42 ℃. At the beginning of drying, the humidity of the object to be dried (e.g., wet laundry) is large, and thus, the temperature difference Δt is large.
In S303, if the temperature difference Δt is smaller than the lowest temperature value within the second preset threshold range, it is proved that the temperature of the drying drum is increased, the temperature difference Δt is decreased, and the corresponding relationship between the preset temperature difference Δt and the power value may be set according to the experimental data.
In S304, the temperature difference value Deltat is approximately equal to 0, which proves that the moisture of the dried object (such as wet clothes) is completely dried, the temperature on the wall of the drying drum is not changed any more, and the temperature is in a constant state. At this time, the power supply may be continued for a second preset time, or may be immediately stopped.
For setting one temperature sensor or a plurality of temperature sensors on the drying roller, the rotating speed of the drying roller is preferably adjusted every time the power is adjusted, and the rotating speed is adjusted according to an increasing trend. Therefore, the speed of the drying drum can be reduced when the object to be dried (such as wet clothes) is in a wet initial state, so that the object to be dried (such as wet clothes) can be fully contacted with the wall of the drying drum to take away moisture, the moisture of the object to be dried (such as wet clothes) is reduced along with the drying time, and the drying drum can be accelerated to operate so that the object to be dried (such as wet clothes) is heated and dried as uniformly as possible.
Meanwhile, it is preferable that the initial power is full power and the end power is the lowest power. The initial power, the preset temperature value or the corresponding relation between the preset processed value and the power value and the ending power can be set according to actual needs, for example, a plurality of drying modes are set according to the material of the dried clothes, and different drying modes correspond to different initial powers, preset temperature values or the corresponding relation between the preset processed value and the power value and the ending power.
Further, the heating structure can be various, such as a heating wire wound around the drying drum, and in this embodiment, the heating structure is preferably a heating film, and the heating film is used as the heating structure of the drying drum, so that the drying drum is safe, easy to set, and rapid to heat, and can improve the drying efficiency.
