Example 1
As shown in fig. 1, the present embodiment provides a down feather drying control method, as shown in fig. 1 to 4, in the down feather drying process, air temperature in a clothes processing tub is alternately heated and cooled, so that down feather drying is realized while the fluffiness of down feather is maintained. The down feather material is used for down jackets in real life, and the drying process of the down jackets is elaborated in detail in the embodiment, so that the technical scheme in the embodiment is clearer.
The down drying control method comprises a fluffing stage, wherein in the fluffing stage, down in the down jacket can be kept fluffy better while the down jacket is dried; the specific puffing stage comprises a heating stage and a cooling stage; when a user needs to dry the down jacket after washing the down jacket, the down jacket is dried to enter a heating stage through program control of a clothes treatment barrel, and the heating stage is a stage of heating air in the clothes treatment barrel; the down jacket is dried by heating the air in the barrel to raise the temperature in the barrel to reach the temperature required by drying the clothes, so that the aim of drying the down is fulfilled; the heating stage of the fluffing stage is switched to the cooling stage through the program control of the washing machine, the cooling stage cools the air in the clothes treatment barrel, and the environment of the down jacket is cooled after the down jacket is kept at a higher temperature for a certain time through cooling the air temperature in the clothes treatment barrel, so that the down jacket is cooled; by controlling the temperature in the clothes treatment barrel, the temperature in the clothes treatment barrel is not too high, so that the down feather is in a high-temperature and high-humidity state for a long time, and the down feather is curled under the influence of high temperature, and the fluffiness of the down feather is influenced. Certainly, in the cooling stage in this embodiment, the temperature in the laundry processing tub is not higher than a certain value only for controlling the temperature in the tub, the down jacket is cooled after being heated to a certain temperature, and the fluffy characteristic of the down is maintained through temperature transition while the down is dried through high-temperature and low-temperature conversion. Furthermore, the heating stage and the cooling stage in the down feather drying process are controlled to alternately operate, so that the temperature of the down jackets to be dried is alternately switched between high temperature and low temperature, and the down feathers in the down jackets can reach better fluffy characteristic compared with the down feathers before washing by the aid of the alternately changed temperature while the fluffy characteristic of the down feathers is not damaged. Furthermore, the down jacket is cooled before the down jacket is possibly damaged in the drying process, so that the down jacket is cooled to return to the normal temperature, the material property of the down jacket is recovered to the material property in the normal state, the temperature rise in the clothes treatment barrel is controlled again to dry the down jacket, the material property of the down jacket is combined, the temperature in the clothes treatment barrel is controlled to repeatedly change within the bearable range of the material property of the down jacket through matching, and the surface material of the down jacket and the fluffy effect of the down jacket are protected to the greatest extent.
By aiming at the special material and the strict requirement of the down feather material on the drying process, the environment temperature of the down feather is alternately changed between high temperature and low temperature in the drying process; this embodiment when down coat reaches anticipated stoving effect, avoided the material and the fluffy characteristic of stoving back eiderdown to lead to its material and fluffy characteristic to receive the damage because of the stoving operation among the stoving process, solved the difficult technical problem of eiderdown stoving.
Furthermore, the embodiment provides an optimization scheme in the down jacket drying process, wherein the maximum value and the minimum value of the temperature in the clothes treatment barrel are controlled in the down jacket drying process, so that the problem that the material of the down jacket is damaged due to overhigh temperature is further prevented; in the specific implementation process, the temperature in the laundry processing tub can be controlled to reach the maximum value and/or reach the minimum value, and the temperature in the laundry processing apparatus can also be controlled to fluctuate between the maximum value and the minimum value, and the specific temperature, the temperature reaching mode and the fluctuation mode between the maximum value and the minimum value in the temperature variation process are not limited herein.
Further optimally, the temperature in the clothes processing barrel is controlled to reach the first set temperature in the heating stage; reaching a second set temperature during the cooling phase; further controlling the air temperature in the clothes processing barrel to reach a first set temperature within a first preset time period; and reaching a second set temperature within a second preset time period. According to different materials of the down jacket and different down materials, the time for the down jacket to reach the first temperature and the second temperature in the drying process is further optimized, so that the surface material of the down jacket and the fluffy characteristic of down in the down jacket are better protected. In the specific implementation process, the first preset time and the second preset time which reach the set temperature in the down feather drying process are further optimized, namely the first temperature and the second temperature are controlled to be reached in a short time in the clothes treatment barrel, so that the fluffy drying process which is alternately carried out by instantaneous high temperature and instantaneous cooling in the down feather drying process is realized, the fabric of the down feather jacket is not damaged in the drying process of the down feather jacket, the original fluffy characteristic of the down feather jacket can be recovered after the down feather jacket is dried, the fluffy characteristic of down feather materials can be further improved through the alternation of the instantaneous high temperature and the instantaneous cooling, and the problem that the fluffy characteristic of the down feather materials is reduced because a user wears the down feather jacket for a long time but does not well care the down feather materials is solved. In the specific implementation process, when the air temperature in the clothes treatment barrel in the heating stage reaches a first set temperature, the air temperature in the clothes treatment barrel is cooled, and the washing machine is controlled to enter a cooling stage; when the air temperature of the clothes processing barrel in the cooling stage reaches the second set temperature, the air temperature in the clothes processing barrel is heated, and the washing machine is controlled to enter the heating stage. The scene that the temperature in the clothes processing barrel is rapidly changed in a short time due to instantaneous high temperature and instantaneous cooling is realized, the drying process of the down jackets is completed under the scene, and the down characteristic is protected to the greatest extent.
The embodiment also provides an alternative scheme for controlling the temperature holding time in the down feather drying stage, when the air temperature in the clothes treatment barrel in the heating stage reaches the first set temperature, the temperature in the clothes treatment barrel is controlled to be maintained at the first set temperature for a third preset time, and then the washing machine is controlled to enter the cooling stage; and when the air temperature in the clothes treatment barrel reaches a second set temperature in the cooling stage, controlling the temperature in the clothes treatment barrel to be maintained at the second set temperature for a third preset time period, and then controlling the washing machine to enter the heating stage. When the temperature of the air in the clothes treatment barrel reaches a first set temperature, the temperature of the clothes treatment barrel is controlled to maintain the first set temperature for a third preset time, so that the down jacket can achieve a better heating and drying effect at the temperature, and the third preset time is selected differently according to the difference between the surface fabric of the down jacket and the down material filler, and is specific. And meanwhile, when the air in the clothes processing barrel reaches a second set temperature, maintaining the second set temperature for a fourth preset time, so that the down jacket to be dried can be further cooled to the second set temperature for a set time, further selecting the second set temperature according to the material characteristics of the outer surface fabric of the down jacket or the down filler of the down jacket, and maintaining the down jacket at the second set temperature for a certain time so that the material characteristics of the down jacket can be restored to the material characteristics before drying and heating. The temperature of the down jacket fluctuates between a higher temperature which can damage the characteristics of the down jacket and a lower temperature which recovers the characteristics of the down jacket through the heating and cooling processes, and the stay duration of the down jacket at different temperatures is further controlled, so that the fluffy characteristic of down in the down jacket is greatly maintained while the drying process is realized; and further protects the surface fabric of the down jacket.
In a specific implementation process, the cycle number of the heating stage and the cooling stage which alternately operate is set, the specific cycle number can be set according to the drying duration of the down jacket, and can be optionally set according to the attribute of the clothes to be dried, and for the down jacket in the embodiment, the attribute of the clothes to be dried can be the material of the clothes; the weight of the down jacket can be the weight of the down jacket before wetting or after dehydration, and is not limited herein. The drying duration of the down jacket and the cycle times of the down jacket at the first set temperature and the second set temperature are controlled by controlling the cycle times of the alternate operation, so that the down jacket is further ensured not to be damaged, and particularly, although the temperature of the down jacket is controlled to periodically change between the first set temperature which possibly damages the down jacket and the second set temperature which ensures that the materials forming the down jacket are recovered to a better characteristic in the drying process, the down jacket keeps the fluffy characteristic to a certain extent and does not damage the fabrics of the down jacket; however, any process needs a certain limit, and if the heating stage and the cooling stage are controlled to operate all the time or operate for too many times periodically, the down jacket can be damaged, so that different cycle times are set for different down jackets, the drying requirement of the down jacket is met, and meanwhile, the material characteristics of the down jacket are further protected from being damaged.
In the above embodiment, focusing on the control and control method of the temperature inside the laundry processing tub during the down jacket drying process, in the drying process described in the above embodiment, the laundry processing tub may rotate according to the drying rotation mode in the existing drying process of the laundry processing tub, or in another way, the laundry processing apparatus performs the rotation drying according to the set drying rotation mode, thereby completing the drying of the down jacket. Meanwhile, the heating and cooling processes in different stages can be matched with a set rotation mode, namely, the down feather drying process controls the clothes treatment barrel to rotate in a first mode, and the first mode comprises that the clothes treatment barrel rotates in a first rotating speed and a first rotation-stop time sequence ratio which are adaptive to the heating stage and/or the cooling stage in the heating stage and/or the cooling stage; further optionally, the first rotation speed and the first rotation stop sequence ratio of the heating stage and/or the cooling stage control the laundry treatment tub to rotate in a first mode according to a temperature profile in the laundry treatment tub, the rotation mode including adjusting the first rotation stop sequence ratio according to a first rotation speed of the temperature profile corresponding to a rise or fall of the temperature profile with a rise or fall of the temperature profile and/or corresponding to a rise or fall of the temperature profile with a fall of the temperature profile. In the specific implementation process, the transfer-stop time sequence ratio is the ratio of the time length of the rotation process and the time length of the stop process, and the larger the transfer-stop time sequence ratio is, the longer the corresponding time length of the rotation process is.
Further optimally, the puffing stage described in the above embodiment further includes a pre-drying stage; the pre-drying stage is a preparation stage before the down jacket enters the fluffing stage; the down jacket can better adapt to the temperature and/or rotating speed change process of the subsequent pre-drying stage through the pre-drying stage of the down jacket, and meanwhile, as the water content of the down jacket is more when the down jacket is just dried, the periodic heating and cooling drying process of the down jacket in the subsequent fluffy stage can be influenced, and the pretreatment is carried out on the down jacket to be dried, so that the fluffy stage of the down jacket can achieve a better drying effect. In the specific implementation process, air in the clothes processing barrel is preheated; and controlling the laundry treating tub to rotate in a second mode, the second mode being that the laundry treating tub rotates at a second rotation speed and a second rotation-stop timing ratio; the second rotating speed is greater than the first rotating speed of the clothes processing barrel in the fluffing process, and the second rotation-stop time sequence ratio is higher than the first rotation-stop time sequence ratio of the clothes processing barrel in the fluffing process; further optimally, the preset operation time length of the pre-drying stage is controlled, the preset operation time length is a third preset operation time length in the embodiment, and when the pre-drying stage reaches the third preset operation time length, the washing machine is controlled to enter the fluffing stage; in the specific implementation process, the third set time range is 3min-10 min.
Optionally, a weighing detection stage is further included before the pre-drying stage, the weighing detection is to weigh down to be dried, and the moisture content of the down jacket entering the drying stage is further controlled by controlling the weight of the down jacket entering the drying stage; in the washing and drying process of an actual down jacket, the down jacket may contain more water before being dried due to the material characteristics of the down jacket, when the water content in the down jacket is too much, the drying time of the down jacket is increased, and further, the water content of the down jacket entering the drying stage is too high, so that the clothes processing device is influenced to perform more professional processing on the down jacket in the fluffy stage, and the purpose of protecting the fabric of the down jacket and recovering the fluffy characteristic of the down jacket in the fluffy stage can not be achieved. In the specific implementation process, judging whether the weight of the down feather is less than a set limit value; if yes, entering a pre-drying stage; if not, dehydrating the down to be dried and entering a weighing detection stage again; the set limit value is determined according to the processing capacity of the clothes processing barrel and/or the weight and/or the water content required by the down jacket entering the drying stage in the subsequent down drying process.
Further, when the clothes processing barrel is controlled to alternately run in the heating stage and the cooling stage, the clothes processing barrel is controlled to enter the drying and cooling stage; the drying and cooling stage stops heating the air of the clothes processing barrel and controls the clothes processing barrel to rotate in a third mode, and the third mode is that the clothes processing barrel rotates at a third rotating speed and a third rotating-stopping time sequence ratio; the third rotating speed is less than the first rotating speed of the clothes processing barrel in the fluffing process, and the third rotating-stopping time sequence ratio is less than the first rotating-stopping time sequence ratio of the clothes processing barrel in the fluffing process.
