The present invention has been made in view of this situation.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a control method of a quick clothes dryer and the quick clothes dryer, wherein the control method judges the drying degree of clothes according to the temperature of the clothes and the temperature of drying air.
In order to solve the technical problems, the invention adopts the technical scheme that:
a control method of a quick clothes dryer is characterized in that the clothes dryer judges the drying degree of clothes according to the temperature of the clothes and the air temperature of drying air, and controls the clothes drying process.
In the clothes drying process, moisture in the clothes is heated and evaporated, and a large amount of heat can be taken away by the moisture evaporation, so that the temperature of the clothes is in a lower range. The temperature of the clothes gradually rises along with the reduction of the moisture in the clothes, when the moisture in the clothes is totally or almost totally evaporated, the temperature of the clothes is close to the temperature of the drying air to mark that the clothes is dried, and the clothes dryer judges the drying degree of the clothes according to the temperature of the clothes and the air temperature of the drying air. The clothes dryer has the advantages that the temperature is preset in the clothes dryer, the clothes temperature is compared with the preset temperature, the setting mode (numerical value) is single, the clothes temperature cannot be adjusted according to actual use conditions or environment conditions, the adaptability is poor, the clothes temperature is compared with the gas temperature of drying air, the principle is more reasonable, and the control is more accurate.
The clothes dryer calculates the temperature difference between the air temperature and the clothes temperature, judges the drying degree of the clothes according to the temperature difference, and controls the wind speed of drying air and/or the temperature of the drying air and/or the closing of the clothes dryer in the clothes drying process.
Through calculating the temperature difference between the air temperature and the clothes temperature, when the temperature difference is large, the clothes are indicated to be not dry, the temperature difference can be used as the basis for controlling the air speed and the temperature, the drying process is more intelligent, the clothes drying speed is higher, when the difference is 0 or the difference is very small, the clothes are indicated to be dried, the clothes dryer is controlled to be closed, the control method is more accurate in controlling the clothes drying process, and the application range of the clothes dryer is wider.
The clothes dryer presets a difference value delta T between the air temperature and the clothes temperature, calculates T1-T2 according to the air temperature value T1 and the clothes temperature T2 and compares the calculated value with the delta T, if T1-T2 is larger than or equal to the delta T, clothes drying is continued, and if T1-T2 is smaller than the delta T, the clothes drying is finished.
The difference value delta T is preset in the clothes dryer, so that the actual temperature difference between the calculated gas temperature value T1 and the clothes temperature T2 is compared with the preset delta T, the automatic closing of the clothes dryer is realized, and the clothes dryer is more intelligent and more convenient to use.
The dryer presets a time threshold or a temperature threshold for starting to calculate the difference between the air temperature T1 and the laundry temperature T2, and when the time reaches the time threshold or the temperature rises to the temperature threshold, the dryer calculates the temperature difference T1-T2.
In the stage of starting the clothes dryer, the temperature of the clothes and the temperature of the air of the drying air are both in a low temperature range, and the difference between the clothes and the air is possibly small, so that the clothes dryer is easily judged by mistake. Through presetting a time threshold or a temperature threshold, when the temperature or the time reaches the threshold, calculating T1-T2, reducing the possibility of error judgment of the clothes dryer, enabling the judgment to be more accurate and reasonable, and enabling the clothes dryer to be more intelligent.
The clothes dryer is preset to perform calculation of the lowest temperature Tc of drying air from T1 to T2, if T1 is less than or equal to Tc, the clothes dryer does not calculate T1 to T2 and continues to dry the clothes, and if T1 is more than Tc, the temperature difference T1 to T2 is calculated.
After the machine is started for a period of time, the drying air is heated to Tc, and the difference between T1 and T2 is very large, so that the possibility of erroneous judgment generated when the temperature is low is eliminated.
The dryer judges whether the drying air is overheated according to the air temperature T1, and reduces the temperature of the drying air if overheated.
The dryer judges whether the temperature of the drying air is too low according to the air temperature T1, and if so, raises the temperature of the drying air.
During the whole drying process, the drying speed is increased due to the overhigh drying temperature, but the clothes can be damaged. For the clothes dryer which dries clothes through the air bag, the temperature of drying air is too high, when a person touches or is close to the clothes dryer, the clothes dryer is easily scalded by the drying air or hot steam brought out by the drying air, and the temperature of the drying air is controlled to be a proper temperature by judging whether the air temperature of the drying air in the clothes dryer is too high or too low, so that the requirement of quickly drying clothes can be met, and the clothes dryer can be prevented from being scalded.
The clothes dryer comprises a heating device for heating drying air and an air blowing device for conveying the drying air, when clothes are dried, the heating device is controlled to be closed firstly by the clothes dryer, and the air blowing device is closed later.
When the drying is finished, the heating device is firstly closed, and the air blowing device is then closed, so that the heated drying air is completely discharged, and the damage to the heater or the clothes dryer is reduced.
The control method comprises the following steps:
s10, starting the clothes dryer;
s20, detecting the air temperature T1 of the drying air by the clothes dryer;
s30, comparing the T1 with Tc, continuing to heat when the T1 is less than or equal to Tc, and operating S40 when the T1 is more than Tc;
s40, detecting clothes temperature T2 by the clothes dryer, comparing the difference delta T between preset gas temperature and clothes temperature with T1-T2, when T1-T2 is larger than or equal to delta T, continuously comparing the sizes of T1-T2 and delta T, and when T1-T2 is smaller than delta T, closing a heating device and a blowing device of the clothes dryer, and finishing clothes drying.
A quick clothes dryer with the control method comprises a base, an air bag arranged on the base and used for drying clothes, a drying device used for providing drying air for the air bag, a first temperature detection device used for detecting the temperature of the drying air, a second temperature detection device used for detecting the temperature of clothes and a control device, wherein the first temperature detection device, the second temperature detection device and the drying device are all electrically connected with the control device, and the control device controls the drying device according to the temperature of the drying air and the temperature of the clothes.
The drying method is particularly suitable for the clothes dryer with the air bag, and because the drying air passes through the air bag to dry the clothes and takes away the moisture on the clothes, the drying air in the air bag has little influence on the detection of the temperature of the clothes. For the drum type clothes dryer, the clothes are located in the drying air, the influence of the drying air on the temperature of the clothes is large, and the judgment error is large. The structure is provided with a first temperature detection device and a second temperature detection device which are used for respectively detecting the gas temperature of the drying air and the temperature of the clothes, and the control device controls the drying device according to the temperature of the drying air and the temperature of the clothes.
After adopting the technical scheme, compared with the prior art, the invention has the following beneficial effects: in the clothes drying process, moisture in the clothes is heated and evaporated, and a large amount of heat can be taken away by the moisture evaporation, so that the temperature of the clothes is in a lower range. The temperature of the clothes gradually rises along with the reduction of the moisture in the clothes, when the moisture in the clothes is totally or almost totally evaporated, the temperature of the clothes is close to the temperature of the drying air to mark that the clothes is dried, and the clothes dryer judges the drying degree of the clothes according to the temperature of the clothes and the air temperature of the drying air. The temperature is preset in the clothes dryer, the clothes temperature is compared with the preset temperature, control is achieved, but the control method completely discharges environmental factors, adaptability is poor, the clothes temperature is compared with the air temperature of drying air, the principle is more reasonable, and control is more accurate; through calculating the temperature difference between the air temperature and the clothes temperature, when the temperature difference is large, the clothes are indicated to be not dry, the temperature difference can be used as the basis for controlling the air speed and the temperature, the drying process is more intelligent, the clothes drying speed is higher, when the difference is 0 or the difference is very small, the clothes are indicated to be dried, the clothes dryer is controlled to be closed, the control method is more accurate in controlling the clothes drying process, the actual environment and various factors are considered, and the application range of the clothes dryer is wider.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and the following embodiments are used for illustrating the present invention and are not intended to limit the scope of the present invention.
The first embodiment is as follows:
as shown in fig. 1 to 2, a control method of a quick dryer, which judges a drying degree of laundry according to a temperature of the laundry and a temperature of air of drying air, controls a drying course.
In the clothes drying process, moisture in the clothes is heated and evaporated, and a large amount of heat can be taken away by the moisture evaporation, so that the temperature of the clothes is in a lower range. As the moisture in the laundry is reduced, the temperature of the laundry is gradually increased, and when the moisture in the laundry is completely or almost completely evaporated, the temperature of the laundry approaches the temperature of the drying air, indicating that the laundry has been dried.
The clothes dryer judges the drying degree of the clothes according to whether the temperature of the clothes is equal to the temperature of the air of the drying air or whether the temperature of the clothes is close to the temperature of the air, and detects whether the drying is finished.
The structure is particularly suitable for a clothes dryer with the air bag 8, the clothes dryer comprises the air bag 8 for supporting and drying clothes and a drying device for blowing drying air into the air bag 8, the detected air temperature is the air temperature in the air bag 8 or the air temperature in an air duct of the drying device, the clothes temperature is the clothes temperature on the air bag 8, in the clothes drying process, the drying air takes away moisture from the clothes, so that the temperature of the clothes is reduced, the device for detecting the air temperature is generally arranged at a position far away from the air bag, the detection end of the device for detecting the clothes temperature is generally abutted against the clothes or inserted into the clothes, the influence of the air temperature in the air bag 8 on the clothes temperature is small, and the judgment is more accurate.
The clothes dryer calculates the temperature difference between the air temperature and the clothes temperature, judges the drying degree of the clothes according to the temperature difference, and controls the wind speed of drying air and/or the temperature of the drying air and/or the closing of the clothes dryer in the clothes drying process.
The clothes dryer calculates the temperature difference between the air temperature and the clothes temperature, when the temperature difference is equal to 0, namely the air temperature is equal to the clothes temperature, the clothes is marked to be completely dried, the clothes drying is judged to be completed, and the clothes dryer is controlled to be closed.
The clothes dryer can also calculate the temperature difference between the air temperature and the clothes temperature according to the air temperature and the clothes temperature, then compare the temperature difference calculated twice, and when the temperature difference calculated twice is not changed, the clothes are marked to be dried.
The clothes dryer can also calculate the temperature difference between the air temperature and the clothes temperature, when the temperature difference is larger, the air speed of the drying air and/or the temperature of the drying air are/is increased, the drying speed is accelerated, and when the temperature difference is smaller, the air speed of the drying air and/or the temperature of the drying air are/is reduced, and the clothes drying process is controlled.
Or a smaller temperature difference range or temperature value can be preset, and when the difference value between the air temperature and the clothes temperature is within the preset temperature range or is smaller than the preset temperature value, the clothes drying is marked to be finished, and the clothes dryer is controlled to be closed.
Further, the clothes dryer presets a difference value delta T between the air temperature and the clothes temperature, according to the air temperature value T1 and the clothes temperature T2, T1-T2 is calculated and the obtained result is compared with the preset delta T, if T1-T2 is larger than or equal to the delta T, clothes drying is continued, and if T1-T2 is smaller than the delta T, the heating device 4 and the air blowing device 2 of the clothes dryer are closed, and clothes drying progress control is achieved.
The control device 5 of the clothes dryer calculates T1-T2 and compares the obtained result with the delta T, when T1-T2 is more than or equal to the delta T, the clothes are not dried, the clothes are continuously dried, the air temperature detected by the clothes dryer is differed from the clothes temperature at intervals, the obtained value of T1-T2 is compared with the delta T, if T1-T2 is more than or equal to the delta T, the clothes are continuously dried until T1-T2 is less than the delta T, the water content in the clothes is less, the evaporation of the water is less, the clothes are dried, and the heating device 4 and the blowing device 2 of the clothes dryer are turned off by the control device 5 of the clothes dryer.
Further, when the clothes dryer is turned off, the control device 5 controls the heating device 4 to be turned off firstly, then controls the air blowing device 2 to be turned off, if the air blowing device 2 is turned off firstly or the air blowing device and the air blowing device are turned off simultaneously, the temperature near the heating device 4 is not easy to diffuse, the service life of the heating device 4 is influenced, the heating device 4 is turned off firstly, and the residual temperature of the heating device 4 is discharged through the air blowing device 2, so that the heating device 4 and the clothes dryer are prevented from being damaged.
Further, prior to the calculation of T1-T2, preconditions for performing the above calculations are preset: the preset starting calculation of the time threshold or temperature threshold of the difference T1-T2 between the air temperature T1 and the laundry temperature T2, when the time reaches the time threshold or the temperature reaches the temperature threshold, the dryer calculates T1-T2 and compares T1-T2 with DeltaT.
In the initial starting stage of the clothes dryer, the clothes temperature and the air temperature of the drying air are both in the low temperature range, and the values of the two are very close to each other, which may cause the judgment result to be T1-T2 <. DELTA.T, so that the clothes dryer makes a wrong judgment, the heating device 4 and the blowing device 2 of the clothes dryer are turned off, and therefore, the prerequisite condition for performing the calculation of T1-T2 needs to be set.
The prerequisite condition may be a temperature threshold value preset in the dryer, and when the temperature of the drying air of the dryer is less than the temperature threshold value, the calculation of T1-T2 is not performed, and when the temperature of the drying air is greater than the temperature threshold value, the calculation of T1-T2 is performed.
Specifically, the lowest temperature Tc of the drying air of T1-T2 is preset to be calculated, if T1 is not more than Tc, the calculation of T1-T2 is not performed, the clothes are continuously dried, if T1 is more than Tc, the calculation of T1-T2 is performed, and T1-T2 is compared with DeltaT.
The prerequisite condition may also be a temperature threshold preset in the dryer, and when the temperature of the laundry is less than the temperature threshold, the calculation of T1-T2 is not performed, and when the temperature of the laundry is increased to be greater than the temperature threshold, the calculation of T1-T2 is performed.
The prerequisite condition can also be that a preset time threshold value is preset in the clothes dryer, the drying time T of the clothes dryer after the clothes dryer is started is calculated, and when T is greater than the preset time threshold value, T1-T2 is calculated; when T is less than the time threshold, the temperature of the dryer may not be stabilized, and the dryer does not calculate T1-T2 and continues to dry the laundry.
During the whole drying process, the drying speed is increased due to the overhigh drying temperature, but the clothes can be damaged. There is another drawback in the case of the clothes dryer which dries clothes through the air bag 8, that the user easily gets burned when touching the air bag 8 or clothes when the air temperature is too high, and that the danger is too high especially for children.
The clothes dryer judges whether the drying air is overheated or not according to the air temperature T1, and then controls the on-off of the heating device 4 of the clothes dryer or adjusts the heating power of the heating device 4 of the clothes dryer;
further, a maximum temperature Tb is preset, and when T1 > Tb, the heating device 4 is turned off or the heating power of the heating device 4 is reduced.
In the clothes drying process, the highest temperature Tb is preset, and when the air temperature T1 is greater than Tb, the heating device 4 is closed or the heating power of the heating device 4 is reduced, so that the air temperature of the drying air is reduced.
The clothes dryer judges whether the temperature of the drying air is too low according to the air temperature T1, and then controls the on-off of the heating device 4 or adjusts the heating power of the heating device 4 of the clothes dryer;
further, when the gas temperature T1 < the minimum gas temperature Ta, the heating power of the heating device 4 is increased or the heating device 4 is restarted.
When the heating device 4 is turned off or the heating power of the heating device 4 is reduced for a period of time, the gas temperature of the drying air is reduced, and if the gas temperature is too low, it is not beneficial to dry the clothes quickly, therefore, by setting the minimum gas temperature Ta, when the gas temperature T1 < the minimum gas temperature Ta, the heating power of the heating device 4 is increased or the heating device 4 is restarted, the temperature of the drying air is increased.
Through foretell accommodation process, can be with the control of stoving gas temperature at a comparatively suitable temperature range, can satisfy the requirement of fast drying clothing and can not produce danger because of the high temperature again.

s40, detecting clothes temperature T2 by the clothes dryer, comparing the temperature difference delta T between the preset air temperature and the clothes temperature with T1-T2, when T1-T2 is larger than or equal to the delta T, continuously comparing the sizes of T1-T2 and the delta T, when T1-T2 is smaller than the delta T, closing the heating device 4 and the air blowing device 2 of the clothes dryer, and finishing clothes drying.
