- the drying process is further refined by using this threshold (ie, the first moisture content threshold), and the drying cylinder is controlled to rotate alternately in the forward and reverse directions only in the second heating stage.
- This control method is compared with the entire drying process to control the drying process. In terms of the forward and reverse rotation of the dry cylinder, it can not only avoid the knotting and entanglement of heavy loads during the drying process, but also shorten the drying time and improve the user experience.

- FIG. 2 is a flowchart of the control method of the clothes drying equipment of the present invention.
- a clothes dryer usually includes a body and a drying cylinder and a heating device arranged in the body.
- the drying cylinder can accommodate loads to be dried (such as clothes, bedding, towels, blankets, etc.), and pass through its own Rotation drives the load to keep turning inside it.
- the heating device can provide hot air flow into the drying cylinder, and the flow of the hot air flow can evaporate and disperse the loaded moisture. Through the combined action of the drying drum and the heating device, the drying of the load is finally realized.
- the existing clothes dryer has a simple control method. When drying a large load, the load is easily knotted and entangled. When drying a small load, if the load includes a load with a high moisture content, it is easy to cause uneven drying. In other words, the existing clothes drying equipment cannot perform targeted control based on the size of the load, resulting in a poor user experience.
- the clothes drying process of the clothes dryer of the present application mainly includes the following five stages: load determination stage, first The heating stage, the second heating stage, the heating stage and the cold air stage, and the five stages are executed in sequence.
- the heating device When the clothes dryer runs in the load determination phase and the cold air phase, the heating device emits cold air, and when the clothes dryer runs the remaining first heating phase, second heating phase, and drying phase, the heating device emits hot air.
- the heating device when the heating device is turned on, its specific heating power, air outlet temperature and other parameters are not described in detail in this application.
- Those skilled in the art can make selections based on the specific dryer model, operation mode, and clothing type. The specific value does not limit the application.
- control method of the clothes dryer of the present application mainly includes the following steps:
- the drying drum can be controlled to rotate in one direction, and the heating device can be controlled to blow cold air, by setting a humidity sensor (such as a resistive humidity sensor or (Capacitive humidity sensor) detects the length of time the load is in contact with the humidity sensor to determine the size of the load; or determines the size of the load by collecting the current size and current change rate of the driving motor when the drying drum rotates.
- a humidity sensor such as a resistive humidity sensor or (Capacitive humidity sensor
- the drying drum is controlled to rotate in one direction during the first heating stage, and the drying drum is controlled to rotate positively and negatively during the second heating stage; for example, in this step, after the load is determined, it is necessary to Perform different drying controls for different load sizes.
- the drying cylinder is controlled to rotate in one direction throughout the first heating stage, alternately rotate forward and backward during the entire second heating stage, and then rotate again in one direction during the heating stage.
- the control method of the present application can effectively prevent the load from knotting and entanglement while ensuring the drying effect, reducing the drying time, and improving user experience .
- FIG. 3 is a logic diagram of a control method of a clothes drying device in a possible embodiment of the present invention.
- the process of determining the load size may be: controlling the drying drum to rotate forward and the heating device to emit cold air; obtaining multiple humidity values one after another within the first preset time ; Calculate the number of humidity values greater than or equal to the first humidity threshold among the multiple humidity values; when the number is greater than or equal to the preset number or the proportion of the total number is greater than the preset ratio, the load is judged to be a heavy load; otherwise, the load is judged For a small load.
- the sequential acquisition may be continuous acquisition or acquisition at a certain time interval, the same below.
- a resistive humidity sensor is installed at the opening of the drying cylinder.
- the sensor has a pair of metal strip electrodes.
- the resistance between the two electrodes can be detected.
- the moisture content of the load is different
- the resistance value is also different, but the moisture content is approximately proportional to the resistance value.
- the resistance value increases as the moisture content of the load decreases. Therefore, the resistance value can be used to judge the moisture content of the load. In the same way, the resistance value can also be used to determine the humidity value of the load.
- both the load and the air are in contact with the two metal electrodes, and the resistance between the load and the air and the electrodes is measured through the conduction of the two metal strips.
- the load is large, the area is relatively large, and the frequency of contact with the metal strip electrode is high. That is, the metal strip electrode has more contact times with the load and less contact with the air. Therefore, the metal electrode The number of resistance values (humidity values) generated by load contact is large, and the number of resistance values (humidity values) exceeding the resistance threshold (first humidity threshold) is large.
- the load area is relatively small, and the frequency of contact with the metal strip is low, that is, the number of times the metal strip electrode contacts the load is less, and the number of contacts with the air is more. Therefore, the measured metal electrode and the load per unit time
- the number of resistance values (humidity values) generated by contact is small, and the number of resistance values (humidity values) exceeding the resistance threshold (first humidity threshold) is small.
- first humidity threshold the number of humidity values greater than or equal to the first humidity threshold among the multiple humidity values collected within the first preset time, and comparing the number with the preset number or the proportion of the total number, that is The size of the load can be determined.
- the resistance value is collected every 0.4s within 2 minutes, and a total of 300 resistance values are collected.
- the number of resistance values greater than the resistance threshold is 240, which is greater than the preset number of 200, so it is determined that the current load is a heavy load. Determining the load size by the proportion is the same as this, so I won't repeat it.
- the first preset time, interval time, preset number, etc. are all examples, which can be adjusted by those skilled in the art.
- the first heating stage, the second heating stage, and the baking stage switch between different stages based on the moisture content of the load.
- the drying drum is controlled to rotate forward in the first heating stage, and In the second heating stage, the positive and negative rotations are alternately rotated to prevent the load from being twisted.
- control method further includes: when the load is a small load, determining whether the load includes a high moisture content load during the first heating stage of the dryer operation; When the load includes a high water content load, the first heating stage is controlled to run for at least a second preset time.
- the drying time is relatively short, once the small load includes a load with a higher moisture content, uneven drying is likely to occur. Therefore, when it is determined that the load is a small load, it is necessary to further determine whether the load includes a load with a high moisture content during the operation of the first heating stage. If the load includes a load with a higher moisture content, control the first heating stage to run at least the first heating stage. 2. Preset time to ensure that the load with higher moisture content is fully dried, and then determine whether to enter the next stage based on the moisture content of the load.
- the drying drum can be controlled to rotate forward, and the first heating stage can be controlled to run for at least a second preset time, such as at least 30 minutes.
- the second preset time is not restrictive, and it can be adjusted based on the specific model of the clothes dryer.
- the second preset time can also be any value within 20-40 minutes.
- judging whether the load includes a high-moisture content load can be performed in the following manner: successively obtain multiple humidity values of the load; when there is a difference between the latter humidity value and the previous humidity value among the multiple humidity values When the difference between the two is greater than or equal to the second humidity threshold, it is determined that the load includes a high moisture content load.
- the inventor's experimental research found that during the operation of the first heating stage, with the passage of time, the humidity and moisture content of the load are decreasing, but because the moisture content of different materials is different, their decreasing speed is also There is a big difference, especially when there is a load with a higher moisture content in the mixed load (that is, a load with a high moisture content), the humidity value collected by the humidity sensor does not form a continuous decline curve, but in the high moisture content load and humidity When the sensor is in contact, there will be a reverse sudden change in the humidity value, or the humidity curve will show a beating similar to an electrocardiogram in the descending stage.
- the humidity value of the load that is, the humidity value greater than the first humidity threshold
- the multiple humidity values meet the above characteristics, that is, whether there is a next humidity value and a previous humidity value. If the difference between the humidity values is greater than the second humidity threshold, it can be determined whether the load includes a high moisture content load.
- FIG. 4 is a load humidity curve diagram of the drying process in a possible embodiment of the present invention.
- the abscissa is the drying time
- the ordinate is the collected humidity value.
- the humidity value has obvious reverse fluctuations during the decline, and the difference between the next humidity value and the previous humidity value at this fluctuation is greater than 300, so it can be determined that the load includes a high moisture content load.
- the above-mentioned second humidity threshold 300 is only an example, and those skilled in the art can adjust it.
- the drying phase is entered. Specifically, after entering the heating stage, first determine the heating time based on the operating time of the first heating stage, the operating time of the second heating stage and the heating coefficient, and then use the control drying drum to rotate in one direction and continue the heating Bake time.
- the running time length of the first heating stage and the second heating stage can be recorded when the two start to run, and be stored separately at the end of the two stages.
- the heating time can be calculated as follows: first determine the heating coefficient based on the load type, the determination of the load type can be determined in the first heating stage or the second heating stage, and the determination method is the same as the above judgment whether the load includes high water content
- the method of rate load is similar, by obtaining the humidity value or moisture content of the load during the heating phase, and analyzing the change of the humidity value or moisture content, such as calculating the humidity change rate, calculating the difference between the humidity, etc., and Compare with the standard thresholds of different types of loads determined by experiments to determine the current type of load.
- the size of the bake coefficient can be further determined based on the comparison between the load type and the bake coefficient.
- the relationship between the load type and the drying coefficient can be determined through experiments, for example, the cotton and linen load has a larger drying coefficient, while the fiber load has a smaller drying coefficient.
- the method for determining the drying coefficient is not unique. Those skilled in the art can also use other possible methods, such as determining based on the drying mode selected by the user before the drying starts, the type of drying clothes, etc., or based on the load size in advance. Setting etc.
- the bake time can be calculated according to the following formula (1):
- t represents the bake time
- T 1 represents the operating time of the first heating stage
- T 2 represents the operating time of the second heating stage
- ⁇ represents the bake coefficient
- the drying cylinder can be controlled to rotate forward and continue the drying time.
- the cold air stage is operated. Specifically, the drying drum is controlled to rotate in one direction and the heating device emits cold air until the temperature of the outlet air of the heating device is less than the temperature threshold. Since the load is in a high temperature state after the bake stage is over, it is necessary to cool the load to prevent users from being burned when picking up the load. For example, the drying drum can be controlled to continue to rotate in the positive direction, and the heating device can be controlled to change to cool air to cool the load. During the cooling process, the outlet air temperature of the heating device is collected in real time. When the outlet air temperature is lower than 50°C, the dryer is controlled to stop and the drying process ends.
- the temperature threshold is not limited to 50°C, and it can also be any value between 30-50°C.
- the advantage of the above embodiment is that the drying process is further refined by using the first moisture content threshold and the second moisture content threshold, and the drying drum is controlled to rotate forward and backward alternately only in the second heating stage when the load is large. Compared with the method of controlling the forward and reverse rotation of the drying drum during the whole drying process, this control method can effectively avoid the knotting and entanglement of the heavy load during the drying process, and can shorten the drying time and improve the user experience.
- the drying drum is controlled to rotate positively and negatively in the second heating stage.
- the load is a small load
- select The operating time of the first heating stage is extended, so that the present application overcomes the defect that the prior art cannot perform targeted control based on the load size, and improves the drying effect and the user experience.
- this application fully takes into account the baking required for different loads.
- the difference between the drying time can dynamically control the drying time, avoid the phenomenon of incomplete drying of clothes, and ensure that different loads have roughly the same drying effect.
- the drying drum and the heating device are controlled to maintain the current operating state until the operating time of the current stage Reach 30min ⁇ After reaching 30min, collect the humidity value of the load at intervals and determine whether the water content of the load is less than or equal to 20%. ⁇ When the water content of the load is less than or equal to 20%, record the operating time of the first heating stage, re-time and control The drying drum continues to rotate in the positive direction, and the heating device is controlled to continue to emit hot air ⁇ during the drying process, continue to collect the moisture content of the load at intervals to determine whether the moisture content of the load is less than or equal to 6% ⁇ when the moisture content of the load is less than or equal to 6%, Record the running time of the second heating stage, use formula (1) to calculate the bake time t 2 , and control the drying drum to continue to rotate forward, control the heating device to emit hot air, and bake the load ⁇ when bake when the time reaches the time t 2, the control flow dryer drum continues

Description
本发明涉及衣物处理技术领域,具体涉及一种干衣设备的控制方法。
干衣机是利用电加热来使洗好的衣物中的水分即时蒸发干燥的清洁类家用电器,对于北方的冬季和南方的“回南天”衣物难干的情况特别需要。
现有的滚筒式干衣机或洗干一体机在烘干衣物时烘干筒一般都是单向转动,这种控制方式成本低、操作简单。但是,随着生活质量的提高,人们对干衣机的要求更多的体现在对衣物的烘干效果上。对于上述低成本的设备来说,在对大负载进行烘干时,负载容易打结缠绕,烘干效果十分差。
相应地,本领域需要一种新的干衣设备的控制方法来解决上述问题。
发明内容
为了解决现有技术中的上述问题,即为了解决现有干衣设备对大负载烘干时存在的负载易缠绕的问题,本发明提供了一种干衣设备的控制方法,所述干衣设备包括烘干筒和加热装置,所述干衣设备的干衣过程包括依次进行的负载确定阶段、第一加热阶段、第二加热阶段、加烘阶段和冷风阶段,所述控制方法包括:
在所述负载确定阶段确定负载的大小;
当所述负载为大负载时,在所述第一加热阶段控制所述烘干筒单向转动,在所述第二加热阶段控制所述烘干筒正反交替转动。
在上述干衣设备的控制方法的优选技术方案中,“确定负载的大小”的步骤进一步包括:
控制所述烘干筒单向转动且所述加热装置出冷风;
在第一预设时间内先后获取多个湿度值;
计算所述多个湿度值中大于等于第二湿度阈值的湿度值的数量;
当所述数量大于等于预设数量或所述数量相对于全部数量的占比大于预设比值时,判定所述负载为大负载;
否则,判定所述负载为小负载。
在上述干衣设备的控制方法的优选技术方案中,所述控制方法进一步包括:
当所述干衣设备运行所述第一加热阶段时,获取所述负载的含水率;
当所述含水率小于等于第一含水率阈值时,控制所述干衣设备运行所述第二加热阶段。
在上述干衣设备的控制方法的优选技术方案中,所述控制方法进一步包括:
当所述干衣设备运行所述第二加热阶段时,获取所述负载的含水率;
当所述含水率小于等于第二含水率阈值时,控制所述干衣设备运行所述加烘阶段。
在上述干衣设备的控制方法的优选技术方案中,“控制所述干衣设备运行所述加烘阶段”的步骤进一步包括:
基于所述第一加热阶段的运行时长、所述第二加热阶段的运行时长和加烘系数,计算加烘时间;
控制所述烘干筒单向转动并持续所述加烘时间。
在上述干衣设备的控制方法的优选技术方案中,所述控制方法进一步包括:
当所述加烘阶段的运行时间达到所述加烘时间时,控制所述干衣设备运行所述冷风阶段。
在上述干衣设备的控制方法的优选技术方案中,“控制所述干衣设备运行所述冷风阶段”的步骤进一步包括:
控制所述烘干筒单向转动且所述加热装置出冷风,直至所述加热装置的出风温度小于温度阈值。
在上述干衣设备的控制方法的优选技术方案中,所述控制方法进一步包括:
当所述负载为小负载时,在所述干衣设备运行所述第一加热阶段的过程中,判断所述负载中是否包括高含水率负载;
当所述负载中包括高含水率负载时,控制所述第一加热阶段至少运行第二预设时间。
在上述干衣设备的控制方法的优选技术方案中,“判断所述负载中是否包括高含水率负载”的步骤进一步包括:
先后获取所述负载的多个湿度值;
当所述多个湿度值中存在后一湿度值与前一湿度值之间的差值大于等于第一湿度阈值时,判定所述负载中包括所述高含水率负载。
在上述干衣设备的控制方法的优选技术方案中,所述控制方法进一步包括:
当所述负载为小负载时,在所述第一加热阶段和所述第二加热阶段控制所述烘干筒单向转动。
本领域技术人员能够理解的是,在本发明的优选技术方案中,干衣设备包括烘干筒和加热装置,干衣设备的干衣过程包括依次进行的负载确定阶段、第一加热阶段、第二加热阶段、加烘阶段和冷风阶段,控制方法包括:在负载确定阶段确定负载的大小;当负载为大负载时,在第一加热阶段控制烘干筒单向转动,在第二加热阶段控制烘干筒正反交替转动。
通过在负载为大负载时控制烘干筒在第二加热阶段正反交替转动,本申请的控制方法能够在保证烘干效果的同时,有效防止负载打结缠绕,减少烘干时间。
发明人通过研究发现,在对大负载烘干时并非在整个烘干过程中都容易产生缠绕,而是在负载含水率低至一定阈值时才容易出现缠绕现象。通过利用该阈值(即第一含水率阈值)将烘干过程进一步细化,并且仅在第二加热阶段时控制烘干筒正反交替转动,这种控制方式相比于烘干全过程控制烘干筒正反转的方式来说,既可以避免大负载在烘干过程中打结缠绕,又能缩短烘干时间,提升用户体验。

现有技术中,干衣机通常包括机体和设置在机体内的烘干筒和加热装置,烘干筒能够容纳待烘干的负载(如衣服、床被、毛巾毛毯等),并通过自身的转动带动负载在其内部不停翻转。加热装置能够向烘干筒内提供热气流,热气流的流动可以将负载的水分蒸发和散出。通过烘干筒和加热装置的联合作用,最终实现负载的烘干。但是,现有的干衣机控制方式简单,在烘干大负载时负载容易打结缠绕,烘干小负载时如果负载中包括含水率较高的负载容易造成烘干不均匀。也即是说,现有干衣设备无法基于负载的大小进行有针对性的控制,造成用户的使用体验不佳。
如图1所示,为解决现有干衣设备对大负载烘干时存在的负载易缠绕的问题,本申请的干衣机的干衣过程主要包括以下五个阶段: 负载确定阶段、第一加热阶段、第二加热阶段、加烘阶段和冷风阶段,并且五个阶段按先后顺序依次执行。当干衣机运行负载确定阶段和冷风阶段时,加热装置出冷风,当干衣机运行其余第一加热阶段、第二加热阶段和加烘阶段时,加热装置出热风。其中,加热装置开启时,其具体加热功率、出风温度等参数在本申请中不作具体描述,本领域技术人员可以基于具体干衣机的型号、运行模式和衣物种类等进行选择,上述参数的具体数值不对本申请构成限制。
如图2所示,本申请的干衣机的控制方法主要包括如下步骤:
S100、在负载确定阶段确定负载的大小;例如,在本步骤中,可以控制烘干筒单向转动,并且控制加热装置吹冷风,通过在干衣机中设置湿度传感器(如电阻式湿度传感器或电容式湿度传感器)检测负载与湿度传感器接触时间的长短来确定负载的大小;或通过在烘干筒转动时,采集驱动电机的电流大小、电流变化率等方式确定负载的大小。
S200、当负载为大负载时,在第一加热阶段控制烘干筒单向转动,在第二加热阶段控制烘干筒正反交替转动;例如,在本步骤中,确定出负载大小后,需要针对不同的负载大小执行不同的烘干控制。在负载为大负载时,控制加热装置吹热风的同时,控制烘干筒在整个第一加热阶段单向转动,在整个第二加热阶段正反交替转动,而后在加烘阶段再次单向转动。
通过在负载为大负载时控制烘干筒在第二加热阶段正反交替转动,本申请的控制方法能够在保证烘干效果的同时,有效防止负载打结缠绕,减少烘干时间,提升用户体验。
下面参照图3,对本申请的一种较为优选的实施方式进行描述。其中,图3为本发明的一种可能的实施方式中干衣设备的控制方法的逻辑图。
如图3所示,在一种较为优选的实施方式中,确定负载大小的过程可以为:控制烘干筒正向转动且加热装置出冷风;在第一预设时间内先后获取多个湿度值;计算多个湿度值中大于等于第一湿度阈值的湿度值的数量;当数量大于等于预设数量或相对于全部数量的占比大于 预设比值时,判定负载为大负载;否则,判定负载为小负载。其中,先后获取既可以是连续获取,也可以是间隔一定时间获取,下同。
举例而言,在烘干筒的投放口处设置电阻式湿度传感器,该传感器具有一对金属条电极,烘干筒在转动过程中负载同时接触两电极时,能够检测到两电极之间的电阻值,负载的含水率不同,电阻值也不同,但含水率与电阻值近似成比例关系。同一组分的负载,电阻值随着负载的含水率降低而增大,因此,可以通过电阻值的大小来判断负载的含水率高低。同理,利用该电阻值也可以判断负载的湿度值大小。
当烘干筒正向转动时,负载和空气都与两金属电极接触,通过两条金属条导通分别测出负载和空气与电极之间的电阻值。当负载较大时,面积相对较大,与金属条电极接触的频率较高,即金属条电极与负载接触的次数多,与空气接触的次数少,因此,单位时间内测得的金属电极与负载接触产生的电阻值(湿度值)的次数较多,则超过电阻阈值(第一湿度阈值)的电阻值(湿度值)的数量较多。当负载较小时,负载面积相对较小,与金属条接触的频率较低,即金属条电极与负载接触的次数少,与空气接触的次数多,因此,单位时间内测得的金属电极与负载接触产生的电阻值(湿度值)的次数较少,则超过电阻阈值(第一湿度阈值)的电阻值(湿度值)的数量较少。此时,通过计算在第一预设时间内采集的多个湿度值中大于等于第一湿度阈值的湿度值的数量,并比较该数量与预设数量的大小或相对于全部数量的占比即可确定负载的大小。
例如,在2min内每隔0.4s采集一次电阻值,共采集300个电阻值。通过比较和统计,300个电阻值中大于电阻阈值的电阻值数量为240个,大于预设数量200个,因此判定当前的负载为大负载。通过占比的方式确定负载大小与此同理,不再赘述。其中,第一预设时间、间隔时间、预设数量等均为为举例说明,本领域技术人员可以对其进行调整。
继续参照图3,在一种较为较为优选的实施方式中,第一加热阶段、第二加热阶段和加烘阶段基于负载的含水率进行不同阶段之间的切换。
申请人通过试验发现,当对大负载进行烘干时,并非整个烘干过程中大负载均存在容易缠绕现象,而是负载在特定的含水率20%-6% 的范围内这种现象更为明显,因此本申请中,可以将20%和6%作为三个阶段的分段标准,当第一加热阶段运行过程中,负载的含水率小于等于20%时,则进入至第二加热阶段运行。同样地,在第二加热阶段运行过程中,当负载的含水率小于等于至6%时,则进入加烘阶段运行。其中,在第一加热阶段和第二加热阶段运行过程中,可以通过上述的电阻式湿度传感器对含水率进行检测,当然也可以另外在干衣机内设置专门用于检测负载含水率的湿度传感器进行检测。再者,上述20%和6%并非是限制性地,本领域技术人员可以基于本申请的原理对该数值进行调整,这种调整并未偏离本申请的保护范围。
由于大负载在烘干过程中,更容易在含水率处于20%-6%的范围时产生缠绕,因此当确定出负载为大负载时,控制烘干筒在第一加热阶段正向转动,而在第二加热阶段正反交替转动,以此来防止负载产生缠绕。
继续参照图3,在一种较为优选的实施方式中,控制方法进一步包括:当负载为小负载时,在干衣设备运行第一加热阶段的过程中,判断负载中是否包括高含水率负载;当负载中包括高含水率负载时,控制第一加热阶段至少运行第二预设时间。
具体地,小负载在烘干过程中,由于烘干时间相对较短,一旦小负载中包括含水率较高的负载时,容易产生烘干不不均匀。因此,当确定出负载为小负载时,需要在运行第一加热阶段时进一步判断是否负载中包括高含水率负载,如果负载中包括含水率较高的负载,则控制第一加热阶段至少运行第二预设时间,保证含水率较高的负载得到充分烘干,而后再基于负载的含水率确定是否进入下一阶段。
举例而言,在负载为小负载且负载中包括高含水率负载时,可以控制烘干筒正向转动,并且控制第一加热阶段至少运行第二预设时间,如至少运行30min等。其中,第二预设时间并非限制性的,其可以基于干衣机的具体型号进行调整,如该第二预设时间还可以是20-40min内的任意值等。
作为一种较为优选的实施方式,判断负载中是否包括高含水率负载可以按照如下方式进行:先后获取负载的多个湿度值;当多个湿度值中存在后一湿度值与前一湿度值之间的差值大于等于第二湿度阈值 时,判定负载中包括高含水率负载。具体地,发明人试验研究发现,在第一加热阶段运行过程中,随着时间的推移,负载的湿度和含水率都在下降,但是由于不同材质的衣物含水率不同,因此它们的下降速度也存在很大区别,尤其是在混合负载中存在含水率较高的负载(即高含水率负载)时,湿度传感器先后采集到的湿度值并非形成一条连续下降曲线,反而在高含水率负载与湿度传感器接触时会出现湿度值的逆向突变,或者说湿度曲线在下降阶段会出现类似于心电图的跳动。此时通过连续获取或间隔一定时间获取负载的湿度值(即上述的大于第一湿度阈值的湿度值),并判断多个湿度值中是否符合上述特征,即是否存在后一湿度值与前一湿度值之差大于第二湿度阈值,便可确定是否负载中包括高含水率负载。
下面参照图4对上述判断过程进行说明,其中图4为本发明的一种可能的实施方式中烘干过程的负载湿度曲线图。如图4所示,横坐标为烘干时间,纵坐标为采集到的湿度值。在图4中的A处,湿度值在下降过程中出现明显的逆向跳动,并且该跳动处后一湿度值与前一湿度值之差大于300,因此可以判定该负载中包括高含水率负载。当然,上述第二湿度阈值300仅为举例说明,本领域技术人员可以对其进行调整。
返回参照图3,无论是大负载还是小负载,在运行第二加热阶段时,通过获取负载的含水率,当含水率小于等于6%时,进入加烘阶段。具体地,当进入加烘阶段后,首先基于第一加热阶段的运行时长、第二加热阶段的运行时长和加烘系数,确定加烘时间,然后用控制烘干筒单向转动并持续该加烘时间。
其中,第一加热阶段和第二加热阶段的运行时长可以在二者开始运行时开始记录,并在两阶段结束时分别存储下来。其中,加烘时间可以按照如下方式进行计算:首先基于负载类型确定加烘系数,负载类型的确定可以在第一加热阶段或第二加热阶段确定,其确定方法与上述判断负载中是否包括高含水率负载的方法类似,通过获取加热阶段运行过程中负载的湿度值或含水率,通过分析该湿度值或含水率的变化状况,如计算湿度变化速率、计算湿度之间的差值等方式,并与试验确定的不同种类的负载的标准阈值进行比较,从而确定当前的负载种类。当负载种类确定后,可以基于负载种类与加烘系数的对照关系进一步确定 加烘系数的大小。其中,负载种类与加烘系数之间的关系可以通过试验确定,如棉麻类负载的加烘系数较大,而纤维类负载的加烘系数较小等。当然,加烘系数的确定方式并不唯一,本领域技术人员还可以采用其他可能的方式,比如基于用户在烘干开始前选择的烘干模式、烘干衣物种类等确定,或者基于负载大小预先设定等。
在确定好上述参数后,可以按照如下公式(1)计算加烘时间:
t=(T
1+T
2)/μ (1)
公式(1)中,t代表加烘时间,T
1代表第一加热阶段的运行时长,T
2代表第二加热阶段的运行时长,μ代表加烘系数。
当确定出加烘时间后,可以控制烘干筒正向转动,并持续该加烘时间。
继续参照图3,当加烘阶段的运行时长达到加烘时间后,运行冷风阶段。具体地,控制烘干筒单向转动且加热装置出冷风,直至加热装置的出风温度小于温度阈值。由于加烘阶段结束后,负载处于高温状态,需要将负载冷却以防用户拿取负载时被烫伤。例如,可以控制烘干筒继续保持正向转动,并且控制加热装置改为出冷风,对负载进行降温。降温过程中,实时采集加热装置的出风温度,当该出风温度低于50℃时,控制干衣机停机,烘干过程结束。其中,温度阈值不限于50℃,其还可以是30-50℃之间的任意值。
上述实施方式的优点在于:通过利用第一含水率阈值和第二含水率阈值将烘干过程进一步细化,并且在负载为大负载时仅在第二加热阶段时控制烘干筒正反交替转动,这种控制方式相比于烘干全过程控制烘干筒正反转的方式来说,既可以有效避免大负载在烘干过程中打结缠绕,又能缩短烘干时间,提升用户体验。
在负载为小负载时,通过在第一加热阶段运行过程中判断负载中是否有含水率较高的负载,如果有则在进入第二烘干阶段之前,延长第一加热阶段的运行时间,使该阶段至少运行第二预设时间,从而让含水率较高的负载能够得到充足的烘干时间,提高烘干效果,避免烘干不均匀的情况出现。
也就是说,通过将烘干阶段分为第一加热阶段和第二加热阶段,当负载为大负载时,控制烘干筒在第二加热阶段正反交替转动,当负载为小负载时,选择性地延长第一加热阶段的运行时长,使得本申请克服了现有技术无法基于负载大小进行有针对性的控制的缺陷,提升了烘干效果了用户体验。
此外,通过针对不同种类的负载设置不用的加烘系数,并且基于加烘系数、第一加热阶段和第二加热阶段的运行时长共同计算加烘时间,本申请充分考虑到了不同负载所需的烘干时长之间的差异性,能够动态控制加烘时长,避免衣物烘干不彻底的现象,保证不同负载均有大致相同的烘干效果。
下面结合图3,对一种可能的实施方式中干衣机的控制过程进行描述。
如图3所示,在一种可能的实施方式中,干衣机启动运行后,首先控制烘干筒正向转动、加热装置出冷风,并在2min内每间隔0.4s采集一个湿度值,共采集300个湿度值→经判断,300个湿度值中对应于负载的湿度值的数量为240个,超过阈值200个,因此判定负载为大负载→确定负载类型后,开始计时,控制烘干筒继续正向转动,控制加热装置出热风,对负载进行烘干→烘干过程中,间隔采集负载的湿度值,一方面基于湿度值的变化判断负载的类型,另一方面判断负载的含水率是否小于等于20%→在负载的含水率小于等于20%时,记录第一加热阶段的运行时长,重新计时,并控制烘干筒正反交替转动,控制加热装置继续出热风,对负载进行防缠绕处理→烘干过程中,继续间隔采集负载的含水率,判断负载的含水率是否小于等于6%→在负载的含水率小于等于6%时,记录第二加热阶段的运行时长,利用公式(1)计算加烘时间t
1,并控制烘干筒正向转动,控制加热装置出热风,对负载进行加烘处理→当加烘处理的运行时间达到时间t
1时,控制烘干筒继续正向转动,控制加热装置出冷风,对负载进行降温→当加热装置的出风温度小于等于50℃时,控制烘干筒停止转动,控制加热装置关闭,烘干过程结束。
仍然参照图3,在另一种可能的实施方式中,干衣机启动运行后,首先控制烘干筒正向转动、加热装置出冷风,并在2min内每间隔0.4s采集一个湿度值,共采集300个湿度值→经判断,300个湿度值中对 应于负载的湿度值的数量为120个,小于阈值200个,因此判定负载为小负载→确定负载类型后,开始计时,控制烘干筒继续正向转动,控制加热装置出热风,对负载进行烘干→烘干过程中,间隔采集负载的湿度值,基于湿度值的变化判断负载中是否有高含水率负载→经比较,采集的湿度值中存在后一湿度值与前一湿度值之差为350,大于阈值300,因此判定负载中含有高含水率负载,此时控制烘干筒和加热装置保持当前运行状态直至当前阶段的运行时间达到30min→达到30min后,间隔采集负载的湿度值并判断负载的含水率是否小于等于20%→在负载的含水率小于等于20%时,记录第一加热阶段的运行时长,重新计时,并控制烘干筒继续正向转动,控制加热装置继续出热风→烘干过程中,继续间隔采集负载的含水率,判断负载的含水率是否小于等于6%→在负载的含水率小于等于6%时,记录第二加热阶段的运行时长,利用公式(1)计算加烘时间t
2,并控制烘干筒继续正向转动,控制加热装置出热风,对负载进行加烘处理→当加烘处理的运行时间达到时间t
2时,控制烘干筒继续正向转动,控制加热装置出冷风,对负载进行降温→当加热装置的出风温度小于等于50℃时,控制烘干筒停止转动,控制加热装置关闭,烘干过程结束。
需要解释的是,虽然在本申请的各实施方式中并未就烘干筒的正反转方向进行具体限定,但这并非是不清楚的,相反,本领域技术人员可以将烘干筒的任意旋转方向作为其正向,这种设置方式不会对本申请的控制方法的执行带来影响。例如,本领域技术人员可以将烘干筒的顺时针旋转作为正向,而将逆时针旋转作为其反向等。
