Description
Technical Field
The invention relates to the technical field of clothes treatment with a drying function, in particular to a clothes drying method and a clothes treatment device applying the method.
Background
The drying principle of most clothes treatment devices in the market at present is similar, and the air is heated through a set of heating element, and the air after heating is brought into a section of thick bamboo by the fan again, and the clothing is heated in a section of thick bamboo and the moisture evaporates into the steam of high temperature and high humidity, and steam is condensed after being contacted with cooling medium directly or indirectly in the interchanger, becomes the comdenstion water and flows out along the interchanger inner wall.
Under the action of a damp and hot environment and a washing reagent, wool fibers or fabric scales can be opened, if the wool fibers or the fabric scales are repeatedly rubbed and extruded at the same time, entangled fibers can slowly creep in a certain direction under the directional friction effect, so that the wool fibers are meshed into a felt, the wool fabric shrinks tightly and is also known as shrinkage, and the shrinkage is aggravated under the condition of friction at higher drying temperature.
In the existing clothes processing device with drying function, the fabric is in a stacking state for a long time in the drying process, the drying uniformity is relatively poor, the surface temperature of the fabric is very high, and the phenomenon of shrinkage is obvious.
In view of the above, the present invention is particularly proposed.
Disclosure of Invention
The present invention is directed to overcoming the disadvantages of the prior art, and provides a clothes drying method and a clothes processing apparatus using the same, which adjust the time, speed, and cycle of rotation of a drum according to the load of clothes, and adjust the drying temperature according to the temperature obtained in real time.
In order to solve the technical problems, the invention adopts the technical scheme that:
the invention provides a clothes drying method, which comprises the following steps: the clothes treatment device controls the drum to intermittently stop rotating and accelerate starting within the drying time according to the clothes load, so that the clothes are uniformly distributed on the inner wall of the drum; the clothes treatment device controls the heat supply of the circulating air according to the temperature of the air outlet of the roller at the same time, so that the surface temperature of the clothes is equal to the preset drying temperature.
In the method, the rotating speed and the rotating period of the roller are adjusted according to the load of clothes, so that the friction between fabrics and the friction between the fabrics and the wall of the roller are reduced, the rotating speed of the roller is set to enable wool fabrics to be uniformly attached to the wall of the roller, relative friction between the wool fabrics and the roller is avoided, and meanwhile, the wool fabrics are in an extended state, so that the drying is facilitated; the air outlet temperature detected in real time is closest to the drying temperature of the surface of the clothes, so that in order to prevent the felting of the wool fabric accelerated by high temperature, the air outlet temperature is used for controlling the supply of the heat of the circulating air, the fabric is controlled to be in a stable temperature range in the whole drying process, and the felting of the wool fabric can not be caused.
According to the method, the clothes processing device selects drying time according to clothes load, and controls the drum to circularly execute a high-speed stage, a stop stage and an accelerated start stage in sequence within the drying time so as to realize intermittent stop and accelerated start of the drum within the drying time; the drum runs at a first rotating speed in a high-speed stage, is kept static in a stalling stage, and runs at a second rotating speed and a third rotating speed in sequence in an acceleration starting stage after stalling, wherein the centrifugal force generated by the drum at the first rotating speed is not less than the gravity of the clothes, the centrifugal force generated at the second and third rotating speeds is not less than the gravity of the clothes, and the third rotating speed is not less than the second rotating speed.
In the method, the drum can enable clothes to be attached to the inner wall of the drum at a first rotating speed at which the centrifugal force is greater than the gravity of the clothes, so that the clothes are prevented from being rubbed and abraded due to relative motion between the clothes and the drum, and the clothes can be stacked in the process of attaching to the drum wall under the condition of more clothes, so that the drying effect is influenced.
According to the method, the acceleration starting stage comprises the steps that the drum rotates at a second rotating speed at least once from the standstill state, the clothes are shaken out and fluffed, then the drum stops rotating, the drum rotates at a third rotating speed, meanwhile, the drum is lifted to the first rotating speed from the third rotating speed at an acceleration a, and the clothes are uniformly distributed on the inner wall of the drum; preferably, the drum is operated at a first rotation speed in a high speed stage, and a centrifugal force generated by the rotation is not less than a weight of the laundry, so that there is no relative movement between the laundry and an inner wall of the rotating drum.
In the method, in order to enable the wool clothes to be more smoothly spread on the inner cylinder wall, the invention also comprises a rotating speed climbing scheme when the drum is accelerated and started. When the drum is started from a static state, the motor firstly runs at least once at a lower second rotating speed for shaking and loosening the clothes, and then runs at a third rotating speed, so that the shaken and loosened clothes are gradually attached to the drum wall, and simultaneously rises to the first state at a higher acceleration a for short time, and the uniformly distributed clothes are thrown to the drum wall with a higher force and are kept attached to the drum wall.
According to the method, the rotating directions of the roller at the first rotating speed, the second rotating speed and the third rotating speed are the same or different; preferably, the drum rotates in the same direction or in the opposite direction at the first rotation speed and the second rotation speed, and the drum rotates in the same direction at the first rotation speed and the third rotation speed.
In the method, the rotating directions of the roller at the first rotating speed, the second rotating speed and the third rotating speed are adjusted, so that on one hand, the shaking, scattering and uniform distribution effects can be further improved, and on the other hand, when the clothes rotating at the first rotating speed are tightly attached to the roller wall and cannot be separated from the roller wall, the clothes can be effectively separated from the roller wall by adopting reverse low-speed rotation.
According to the method, the clothes treatment device adjusts the heating element according to the temperature of the air outlet of the drum, changes the heat supplied to the circulating air in the drum, and enables the surface temperature of the clothes to be equal to the preset drying temperature.
According to the method, the clothes processing device obtains preset drying temperature and air outlet temperature threshold values according to clothes loads, and adjusts the heating element to increase or reduce the heat supply of the circulating air in the drum when the air outlet temperature exceeds the threshold value range; preferably, the upper limit of the air outlet temperature threshold is not higher than the preset drying temperature.
In the method, the clothes processing device obtains the preset drying temperature and the air outlet temperature threshold according to the clothes load, monitors the temperature of the air outlet in real time, and when the air outlet exceeds the upper threshold limit or is lower than the lower threshold limit, changes the heat supply of the drying circulating air in the roller by adjusting the heating element, maintains the surface temperature of the clothes to be equal to the preset drying temperature, and does not continuously rise.

In the method, during the period that the roller stops rotating at the first rotating speed in a deceleration way and starts at the second rotating speed again in an acceleration way, the clothes are shaken and loosely distributed in the roller, compared with the wall attached at the first rotating speed, the volume occupied by the clothes is increased, and the area for receiving the circulating air is also increased, so that the circulating drying air blowing through the roller brings more heat to the clothes, and the surface temperature of the clothes and the temperature of the air outlet are increased. Therefore, the preset drying temperature should be properly reduced in the process, and the upper limit and the lower limit of the temperature threshold of the air outlet are correspondingly reduced, so that the phenomenon of felting caused by the too fast rise of the surface temperature of the clothes in the process is prevented.
