Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. And can be adjusted as needed by those skilled in the art to suit particular applications. For example, although the description has been given taking a dryer to dry laundry as an example, it is apparent that the present invention can be applied to a drum washing machine with a drying function to dry laundry.
First, referring to fig. 1, a drying control method of a dryer of the present invention will be described. Wherein, fig. 1 is a logic diagram of a drying control method of a dryer of the present invention.
As shown in fig. 1, in order to solve the problem of how to reduce the abrasion when the laundry in the drying process collides with the drum during the falling process in the drum, the dryer of the present invention includes a drum, and the drying control method of the dryer includes:
s100, controlling the roller to rotate at a first rotating speed V1Rotate for a first set time T1So that the drum rotates by a set angle; for example, after putting the laundry into the drum, the control unit of the dryer controls the drum to first rotate at a first rotation speed V1Rotate for a first set time T1。
S200, controlling the roller to stop rotating for a second set time T2Or at a second speed V2Rotate for a second set time T2So as to reduce friction between the laundry inside the drum and the drum; wherein, V1＞V2. For example, the laundry operation T1After the time, the speed is reduced to V at a faster speed2Or stop rotating for T2Time to reduce the relative speed of the laundry when it falls into contact with the drum, thereby reducing wear between the laundry and the drum.
The setting mode has the advantages that: when the clothes are dried, the two stages of rising and dropping can be generated in each cycle along with the rotation of the rotary drum, and when the clothes fall in the dropping stage, the larger the relative speed between the rotary drum and the clothes is, the abrasion of each cycle to the clothes isThe larger the rotation speed of the drum is, the higher the first rotation speed V of the drum is in the ascending stage1Rotating to save drying time, stopping the rotation of the drum or rotating at a second lower speed V in the throwing stage2The motion reduces the friction between the clothes and the roller, and protects the clothes.
The contribution of the present invention to the prior art is also: in the prior art, the speed is changed in another time period after the drum rotates for many circles, but no one attempts to change the speed in one circular motion of the drum, so that the wear degree of the clothes is reduced. Through a plurality of trials and experiments, the inventor finds that the modified program is particularly important for the clothes with extremely small abrasion, especially under the operation of drying the clothes, because no buffer medium (such as washing water) exists between the clothes and the drum, and the inventor proposes a control method which is simple but completely different from the invention direction of the skilled person. In addition, in order to guarantee the service life of the motor, a person skilled in the art cannot change the rotating speed rapidly, the method changes the rotating speed rapidly, the partial service life of the motor is sacrificed, but the effect of reducing the abrasion which can be achieved is far beyond the effect which can be achieved by the existing control mode. And, through changing ordinary motor into the servo motor that has more the flexibility, can reduce the drying by a wide margin to the adverse effect of motor damage, this can be realized on the dryer, and the clothing processing capacity to the dryer promotes greatly.
The drying control method of the laundry treating apparatus of the present invention will be described in detail with further reference to fig. 1 and 2.
The specific process of the clothes rising and dropping is shown in fig. 2, the initial position of the clothes is the position of the first in fig. 2, the rising stage is from the first to the second, the dropping stage is from the second to the third to the first, and then the steps are circulated in sequence.
In one possible embodiment, as shown in fig. 2, the set angle is an angle rotated by (i) to (ii), and preferably the set angle is in a range of 150 ° to 180 °. The set angle can be adjusted according to the rotation angle of different clothes during rising so as to meet the requirements of different clothes on the control of the wear degree.
Because the cylinder needs to switch over the rotational speed fast, consequently drying fan should avoid using one with the motor of cylinder to make drying fan can the independent operation, preferably, in order to make the stoving more high-efficient, in the stoving in-process, drying fan is operation all the time, does not carry out midway pause.
Specifically, through the design that the drying fan and the drum operate independently, the drying fan can still dry clothes with high power during the non-rotation period of the drum, particularly during the falling process of the clothes, the drum starts to decelerate, and the drying fan can increase the power to dry the clothes, so that the effect is better.
In a possible embodiment, the first set time T1And a second set time T2May be selected based on the weight and/or texture of the garment. For example, the weight of the laundry may be acquired by weighing the laundry in the drum. When the clothes are light, the rising time can be selected to be shorter, the dropping time is longer, and the first set time T is set1Correspondingly shorter, second set time T2Correspondingly, if the clothes are heavy, the rising time is longer and the dropping time is shorter, and the first set time T is1Correspondingly extended, second set time T2Correspondingly shorter, more preferred options enable less wear on the laundry. Preferably, the first set time T1Preferably 0.35. ltoreq. T1Less than or equal to 0.75 second, T2The value range time of (1) is preferably not less than 0.45 and not more than T20.85 sec or less, more preferably, T1Set to 0.55 seconds, T2Set to 0.65 seconds.
For another example, the material of the clothes can be known by scanning the RFID tag on the clothes. During the movement of the roller, due to T2The short time inevitably occurs that when the clothes fall, the roller is already at V2To V1In the case of an acceleration state, the effect of reducing wear is reduced. Due to different clothes materials, for example, the material of the woolen sweater is easier to wear, at the moment, the second set time T can be properly prolonged2So that the woolen sweater can be rotated at the speed of the roller at every time as V2The time drop is reduced, and when the woolen sweater falls, the roller is already positioned at the V position2To V1The number of acceleration states in time.
In a more preferred embodiment, V1The value range of the rotating speed is preferably that V is more than or equal to 40rpm160rpm or less, more preferably, V is selected1The rotating speed of the rotary drum is 50rpm, the overturning and beating effect of the clothes can be optimal, and the heat and moisture exchange between the clothes and the air is the most sufficient. V2Preferably 0rpm<V235rpm or less, more preferably, V is selected2The rotating speed of the motor is 25rpm, so that the motor is not too fast in speed change on the premise of ensuring that the abrasion is reduced, the running pressure of the motor is reduced, and the service life of the motor is prolonged.
In summary, the dried clothes can reduce the wear of the clothes when the clothes impact the drum in the falling process in the drum by controlling the drum to reduce the rotating speed or stop rotating during the falling process of the clothes. Selecting different T according to the weight and material of clothes1And T2The control method disclosed by the invention is more suitable for practical application, and different controls are realized for different clothes. The drying fan and the roller operate independently, so that the drying is not influenced by the change of the speed of the roller.
It should be noted that the above-mentioned embodiments are only used for illustrating the principle of the present invention, and are not intended to limit the protection scope of the present invention, and those skilled in the art can modify the above-mentioned structure so that the present invention can be applied to more specific application scenarios without departing from the principle of the present invention.
For example, in an alternative embodiment, "controlling the operation of the dryer at all times" is not necessary, and those skilled in the art can reasonably control the operation of the dryer to achieve better drying effect, such as prolonging the drying time, reducing wrinkles, etc., without departing from the principle of the present invention, and thus, all will fall within the scope of the present invention.
Finally, although the present invention is described by taking a dryer as an example, it is obvious that the drying control method of the laundry processing apparatus of the present invention can also be applied to other apparatuses, such as a drum washing machine with drying function.
