Furthermore, the drying degree of the clothes in the drum is detected through a humidity sensor arranged at the air outlet of the drum, and the humidity sensor detects the humidity value of the clothes in the drum in real time or detects the humidity value once every certain time after the clothes in the drum enter a drying program. And acquiring the humidity in the drum through a humidity sensor, judging the current humidity value and the set humidity value, and when the current humidity value is judged to be smaller than the set humidity value, controlling the drum to rotate at a third rotating speed V3 for a certain time, turning off the power supply, and finishing the drying program. The set humidity value is between 10% and 20%, and the humidity values of clothes made of different materials are different according to practical application, for example, the set humidity value of cotton and linen is 20%, the set humidity value of chemical fiber is 16%, the set humidity value of blended fabric is 16%, and the like. When the current humidity value of the clothes in the drum reaches the set humidity value and the water content of the clothes is low, the clothes are controlled to slowly rotate for a certain time to be in full contact with air in the drum, and the clothes are dried by using the waste heat of the air in the drum, so that the resource waste is avoided, and the function of protecting the fibers of the clothes is also achieved. After the current humidity value reaches the set humidity value, the time for controlling the rotation of the drum can be fixed time (such as 5-10 minutes), or the time for controlling the rotation of the drum to stop can be controlled according to the drying degree of the clothes detected by the humidity sensor, and when the clothes in the drum are detected to reach the drying standard, the power supply is controlled to be disconnected, and the drying program is ended.
Further, after the electromagnetic heating module is controlled to be turned off, if the temperature of the gas in the cylinder is detected to be reduced to the set temperature Tmin and the current humidity value is still greater than the set humidity value, the electromagnetic heating module is controlled to be started again and rotate at the first rotating speed V1. After the electromagnetic heating module is closed, the temperature in the drum is too low, the water content of the clothes is high, and the phenomenon that the clothes can not be dried by waste heat is avoided.
As an alternative to the above method, the electromagnetic heating module is provided with a first heating power P1, a second heating power P2 and a third heating power P3, wherein P1> P2> P3:
when the drying program starts, when the roller rotates at a first rotating speed V1, the electromagnetic heating module is controlled to heat at a first heating power P1, the heating temperature is quickly reached, and the drying efficiency is improved; when the temperature in the drum reaches the set temperature Tmax, and the drum rotates at a second rotating speed V2, the electromagnetic heating module is controlled to be switched to a second heating power P2 for heating, so that the heating temperature in the drum is reduced, and the damage to clothes caused by overhigh temperature is avoided; when the current humidity value of the clothes is smaller than the set humidity value, the drum is controlled to rotate at a third rotating speed V3, and meanwhile, the electromagnetic heating module is controlled to be switched to a third heating power P3 for heating, so that the water content of the clothes is low, too high heating temperature is not needed, and electric energy is saved.
The second control method comprises the following steps: the difference from the first control method is that after the temperature in the drum reaches the set temperature, the electromagnetic heating module is controlled to always maintain the temperature to heat the drum, and the electromagnetic heating module is not controlled to be powered off.
Specifically, as shown in fig. 7, the electromagnetic heating module is activated, and the drum is controlled to rotate at a first rotation speed V1, and when the temperature of the gas in the drum is raised to a set temperature T0, the electromagnetic heating module is controlled to maintain the set temperature T0 to heat the drum, and the drum is controlled to rotate at a second rotation speed V2, wherein the set temperature T0 is between Tmin and Tmax. When the clothes are heated to the set temperature T0, the water content of the clothes is obviously reduced, if the clothes are always attached to the cylinder wall, the fibers of the clothes are easy to damage, and therefore the clothes are subjected to speed reduction treatment, so that the clothes are not attached to the cylinder wall any more, the clothes are in better contact with the clothes, the position of the clothes and the contact position of the clothes and the cylinder wall can be conveniently adjusted, and the clothes can be more effectively dried. The set temperature T0 has no possibility of scalding clothes between Tmin and Tmax, and has no problem of low heating speed due to too low temperature.
Further, when the electromagnetic heating module is controlled to keep the set temperature T0 to heat the roller, the current humidity value in the roller is obtained, and when the current humidity value is smaller than the set humidity value, the roller is controlled to rotate at the third rotating speed V3 for a certain time, then the power supply is cut off, and the drying program is finished. The drum is controlled to slowly rotate at a third rotating speed V3 to be in full contact with air in the drum, and the residual heat of the air in the drum is fully utilized to dry the clothes. The detection of the current humidity value, the setting of the set humidity value, and the time for which the drum rotates at the third rotation speed V3 are the same as those of the first control method, and will not be described herein again.
The advantages of the second method over the first method are: in the method, when the temperature in the drum reaches a set temperature T0, the electromagnetic heating module is always controlled to be kept at the set temperature T0 to heat the drum, the set temperature T0 is far smaller than a limit temperature Tmax borne by clothes, the risk of scalding the clothes is reduced, the problem of low heating speed due to too low temperature is solved, and meanwhile, the situation that the clothes cannot reach the drying standard after the electromagnetic heating module is cut off in the first control method and the electromagnetic heating module needs to be restarted is avoided, so that electric energy is wasted and the drying time is prolonged.
In the method, the heating modes of the electromagnetic heating module include the following two modes:
first, the electromagnetic heating module is provided with a first heating power P1, a second heating power P2 and a third heating power P3, wherein P1> P2> P3:
when the drying program starts, when the roller rotates at a first rotating speed V1, the electromagnetic heating module is controlled to heat at a first heating power P1, the drying temperature is quickly reached, and the drying efficiency is improved; when the temperature in the drum reaches the set temperature T0 and the drum rotates at a second rotating speed V2, controlling the electromagnetic heating module to switch to a second heating power P2 for heating, so that the electromagnetic heating module is always kept at the set temperature T0 for heating the drum; when the current humidity value of the laundry is less than the set humidity value, and the drum rotates at the third rotation speed V3, at this time, the magnetic heating module may be controlled to maintain the second heating power P2 at the set temperature T0 to heat the drum, or the electromagnetic heating module may be controlled to switch to the third heating power P3 to heat the laundry, because the moisture content of the laundry is less at this time, the heating power is reduced, and the waste of electric energy is reduced.
In a second mode, the electromagnetic heating modules at least include a first electromagnetic heating module, a second electromagnetic heating module, and a third electromagnetic heating module:
when the drying program starts, the three electromagnetic heating modules are controlled to heat simultaneously when the roller rotates at a first rotating speed V1, the drying temperature is quickly reached, and the drying efficiency is improved; when the temperature in the drum reaches the set temperature T0, the drum rotates at a second rotating speed V2, and the drum is controlled to rotate at a second rotating speed V2, two of the electromagnetic heating modules are controlled to heat, and the electromagnetic heating modules are controlled to be kept at the set temperature T0 to heat the drum; when the humidity of the clothes is smaller than the set humidity value, when the drum rotates at the third rotating speed V3, the two electromagnetic heating modules can be controlled to keep the temperature at the set temperature T0 to heat the drum, or only one of the electromagnetic heating modules can be controlled to heat the clothes, because the water content of the clothes is less at the moment, one electromagnetic heating module can work to reach the drying standard, and the waste of electric energy is reduced.
In this mode, the quantity of electromagnetic heating module is unrestricted, and the producer can set up a plurality of electromagnetic heating modules according to the temperature demand of different grades, and the structure of electromagnetic heating module, the mode of setting are the same with the second kind of scheme in the embodiment one, just do not give unnecessary details here, perhaps, also can adopt the structure and the mode of setting of electromagnetic heating module in the first kind of scheme of embodiment, through the cooperation or the independent work of controlling a plurality of arc heating members, realize the control to a section of thick bamboo internal temperature.
In this embodiment, the first rotation speed V1 is greater than or equal to 80 rpm, the second rotation speed V2 is 50-60 rpm, the third rotation speed V3 is 20-30 rpm, and the control unit of the clothes dryer controls the drum to rotate at different rotation speeds by controlling the motor.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
