Description

一种干衣机的控制方法及干衣机
本申请要求在2021年8月5日提交中国专利局、申请号为202110895705.4的中国专利申请的优先权,该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及家用电器技术领域,例如涉及一种干衣机的控制方法及干衣机。
背景技术
干衣机虽然具有高密封性,但是干衣机毕竟烘干的是经过洗衣机脱水的衣物,所以水不会在干衣机内流动或者滴注,并且考虑成本的因素,干衣机的滚筒以及内循环风道的密封性远低于滚筒洗衣机。所以在烘干过程中,会有湿热空气从滚筒内泄漏出来到箱体内,这些湿热空气遇到干衣机上温度相对较低的塑料件或者金属板材,就会发生凝露,凝露多了以后就会形成水滴,凝结于干衣机的箱体上甚至滴落到地板上,影响用户体验甚至会造成用户经济损失。
相关技术中通改善干衣机的密封性,即在运行部件和静止部件之间增加密封件,虽然改善了密封性,但是要求密封件具有耐磨、耐高温等特性,并且增大了运行部件与静止部件之间的摩擦,会给滚筒电机增加了负荷,提高了干衣机的能耗。还可以通过将泄露的湿热空气排出干衣机箱体内的方式以降低干衣机箱体内形成的冷凝水,通常是在干衣机上设置风扇使干衣机的内外空气进行交换,但是相关技术中风扇通常会随干衣机的启动而启动,随干衣机的关闭而关闭,不能精确控制风扇是否需要开启以及风扇的启停时间,该方式虽然降低了干衣机上形成的冷凝水,但是会增加干衣机的能耗。
因此,亟需提供一种干衣机的控制方法以解决上述技术问题。

响应于需要开启所述风扇,根据烘干时长td确定所述风扇开启的时间节点,并根据所述环境温度Ti确定所述风扇的工作模式;
烘干开始,实时检测衣物含水率,响应于烘干时长达到所述时间节点,开启所述风扇;
响应于检测到所述衣物含水率小于预设含水率,关闭所述风扇。

实施例一
干衣机的箱体内设有滚筒,由于滚筒以及内循环风道的密封性远低于滚筒洗衣机。所以在烘干过程中,会有湿热空气从滚筒内泄漏出来到箱体内,为了避免泄露的湿热空气在箱体内凝结甚至凝结的水流到地面上,本实施例提供了一种干衣机,如图1所示,干衣机包括箱体1,箱体1上设有进气口2和排气口4,进气口2处设有风扇3。风扇3能使外部环境中的空气通过进气口2进入到箱体1内,进而使箱体1内的湿热空气通过排气口4排出,避免湿热空气在箱体1内凝结甚至流到地面上。可选地,将进气口2设置于箱体1的前板上,排气口4设置于箱体1与前板相对的后板上,以增大空气交换的速度,降低湿热空气的冷凝率。
示例性地,为了提高箱体1内湿热空气排出的顺畅性,将进气口2和风扇3设置于底盘位置的前板上,排气口4设置于底盘位置的后板上,即使进气口2、风扇3和排气口4低于滚筒的最低位置设置,滚筒不会阻挡箱体1内外空气的 交换。
本申请提供的干衣机,在箱体上设置风扇、进气口和排气口,风扇能使箱体内与箱体外的空气进行交换,以将箱体内的湿热空气排出,避免冷凝流到箱体上甚至流到地面上,提高了用户使用的满意度,且能精确控制风扇的启停,在有效排出箱体内湿热空气的同时,降低了干衣机的能耗。
实施例二
本实施例提供了一种干衣机的控制方法,应用于实施例一提供的干衣机中,使用该控制方法能精确控制风扇3的启停,在有效排出箱体1内湿热空气的同时,降低干衣机的能耗,提高用户使用的满意度。
示例性地,如图2所示,本实施例提供的干衣机的控制方法主要包括:
获取烘干时长td和环境温度Ti,根据烘干时长td和环境温度Ti判断风扇3是否需要开启。
根据烘干时长和环境温度确定风扇3是否需要开启,若是烘干时间短,则在短时间内不会泄露湿热空气到箱体1内或者泄露很少的湿热空气到箱体1内,则不需要开启风扇3,或者环境温度很高,滚筒内泄露到箱体1内的湿热空气不会冷凝,也不需要开启风扇3,以降低能耗。
响应于需要开启风扇3,根据烘干时长td确定风扇3开启的时间节点,并根据环境温度Ti确定风扇3的工作模式。
若是需要开启风扇3,由于随着烘干时间的加长,从衣物中烘干出来的水分会增多,根据烘干时长确定风扇3开启的时间节点,以确保在烘干出来的水分比较多的时候使用风扇3将湿热空气排出,精确控制风扇3的开启;环境温度低,湿热空气更容易冷凝,环境温度高,湿热空气则不容易冷凝,根据环境温度控制风扇3的工作模式,以在实现有效排出湿热空气的同时,降低能耗。
烘干开始,实时检测衣物含水率,在烘干时长达到时间节点时,开启风扇3。
响应于检测到衣物含水率小于预设含水率,关闭风扇3。
在衣物含水率小于预设含水率时,产生的湿热空气会减少,泄露的湿热空气也会减少,因此关闭风扇3即可,降低干衣机的能耗。
图3是本实施例提供的干衣机的控制方法的详细步骤流程图,下面结合图3详细介绍本实施例提供的干衣机的控制方法。
干衣机的控制方法包括以下步骤:
步骤一、获取烘干时长td和环境温度Ti,判断烘干时长td是否大于预设烘干时间。
示例性地,在本实施例中,根据待烘干衣物的重量和选定的烘干的程序确定烘干时长td。用户根据衣物的材质选择相应的烘干程序,衣物的材质可以为棉麻、丝绸、毛衣、羽绒等,不同的材质对应不同的烘干程序,烘干时长也不同,避免衣物烘不干或者过烘。将待烘干衣物放置于干衣机的滚筒内,通过电机称重的方式获取待烘干衣物的重量,由于电机称重的方式为常规技术,在此不再详细介绍。
环境温度Ti即为干衣机所处环境的温度,一般情况下在干衣机进行烘干工作前,冷凝器出口温度和压缩机排气口的温度与环境温度基本相同,并且冷凝器出口处和压缩机排气口处会设置温度传感器,所以在采集外部环境温度时,无需在干衣机上额外设置温度采集的传感器,将冷凝器出口处的温度或者压缩机排气口处的温度作为环境温度Ti即可。
在本实施例中,在确定完烘干时长td后,判断烘干时长td是否大于预设烘干时间,若烘干时长td小于或等于预设烘干时间,则干衣机的工作时长比较短,不会产生大量的湿热空气泄漏到箱体1内,为了降低能耗,选择不启动风扇3。可以将预设烘干时间设定为40min,在此不作限定。
步骤二,响应于烘干时长td大于预设烘干时间,判断环境温度Ti是否小于预设环温值T。
示例性地,环境温度低,湿热空气更容易冷凝,环境温度高,湿热空气则不容易冷凝,因此,在烘干时长td大于预设烘干时间后,则再根据环境温度Ti 确定是否需要开启风扇3,提高了风扇3控制的精确性。
步骤三、响应于环境温度Ti小于预设环温值,开启风扇3。
在本实施例中,预设环温值可设定为15℃,在环境温度Ti大于或等于预设环温值时,外界温度高,箱体1内的湿热空气不容易冷凝,因此,则不需要开启风扇3,以降低干衣机的能耗。
步骤四、根据烘干时长td确定风扇3开启的时间节点,并根据环境温度Ti确定风扇3的工作模式。
在本实施例中,烘干时长td大于预设烘干时间,若是预设烘干时间设定为40min,则在干衣机工作20min-30min后启动风扇3,通常情况下干衣机的热泵系统升温需要20min-30min,在热泵系统升温达到烘干温度后,滚筒内的湿度变大,泄露的湿热空气也会增多,所以在干衣机工作的20min-30min后启动风扇3。
在本实施例中,预设环温值设定为第一预设环温值Ti1,将小于第一预设环温值Ti1的温度值划分为三个温度区域,在每个温度区域下对风扇3的控制方式不同。响应于环境温度Ti小于第一预设环温值Ti1且大于等于第二预设环温值Ti2,风扇3以启动和停止交替的方式工作,且每次启动的工作时长tw和每次停止的停止时长ts的总和为第一预设时间t1;响应于环境温度Ti小于第二预设环温值Ti2且大于等于第三预设环温值Ti3,风扇3以启动和停止交替的方式工作,且每次启动的工作时长tw和每次停止的停止时长ts的总和为第二预设时间t2;响应于环境温度Ti小于第三预设环温值Ti3,风扇3一直启动;其中,Ti3<Ti2<Ti1,t2<t1。
示例性的,第一预设环温值Ti1可设定为15℃,将低于15℃的温度划分成三个区间,第二预设环温值Ti2设定为10℃,第三预设环温值Ti3设定为5℃,在环境温度Ti大于等于10℃且小于15℃时,箱体1内会出现轻微的冷凝水,将风扇3以启动和停止交替的方式工作,在排出湿热空气的同时降低能耗。在环境温度Ti大于等于5℃且小于10℃时,箱体1内会出现中度冷凝水,风扇3可选以启动和停止交替的方式工作,每次启动和每次停止设定为风扇3运转的 一个循环,在该温度划分方式下,风扇3的一个循环的第二预设时间t2小于第一预设时间t1,例如第一预设时间t1设定为10min,第二预设时间t2设定为4min,以增加风扇3运行的频率,加快湿热空气的排出。在环境温度Ti小于5℃时,箱体1内会出现重度冷凝水,风扇3需要一直打开,以尽快排出箱体1内的湿热空气,避免冷凝。
在每个温度区间下,风扇3每次启动和每次停止的时间也是不同的,在风扇3运行的每个循环下,环境温度Ti高时,湿热空气凝结率低,风扇3每次的工作时长可以短于风扇3每次的停止时长,在环境温度Ti低时,湿热空气凝结率高,风扇3的每次的工作时长可以长于风扇3每次的停止时长。
在本实施例中,在环境温度Ti小于第一预设环温值Ti1且大于等于第二预设环温值Ti2,风扇3的工作时长tw为第一预设时间t1的35%-44%,可选占比为35%、36%、37%、38%、39%、40%、41%、42%、43%或44%,第一预设时间t1减去工作时长tw即为停止时长ts。
响应于环境温度Ti小于第二预设环温值Ti2且大于等于第三预设环温值Ti3,风扇3的工作时长tw为第二预设时间t2的45%-55%,可选占比为45%、46%、47%、48%、49%、50%、51%、52%、53%、54%或55%,第二预设时间t2减去工作时长tw即为停止时长ts。
步骤五、烘干开始,实时获取衣物含水率,在烘干时长达到时间节点时,开启风扇3。
在本实施例中,干衣机内设置有用于检测衣物含水率的湿度传感器,在干衣机烘干开始后,湿度传感器实时检测衣物含水率。风扇3按照步骤四设定的工作模式进行工作。
步骤六、响应于衣物含水率小于预设含水率,关闭风扇3。
在本实施例中,一般衣物含水率低于20%后,泄露的湿热空气比较少,可以关闭风扇3,降低能耗,因此通过衣物含水率确定风扇3关闭的时间点。
本申请提供的干衣机的控制方法,根据烘干时长和环境温度确定风扇是否 需要开启,若是烘干时间短,则在短时间内不会泄露湿热空气到箱体内或者泄露很少的湿热空气到箱体内,则不需要开启风扇,或者环境温度很高,滚筒内泄露到箱体内的湿热空气不会冷凝,也不需要开启风扇,以降低能耗;若是需要开启风扇,由于随着烘干时间的加长,从衣物中烘干出来的水分会增多,根据烘干时长确定风扇开启的时间节点,以确保在烘干出来的水分比较多的时候使用风扇将湿热空气排出,精确控制风扇的开启;环境温度低,湿热空气更容易冷凝,环境温度高,湿热空气则不容易冷凝,根据环境温度控制风扇的工作模式,以在实现有效排出湿热空气的同时,降低能耗;在衣物含水率小于预设含水率时,产生的湿热空气会减少,泄露的湿热空气也会减少,因此关闭风扇即可,降低干衣机的能耗。本申请提供的干衣机的控制方法能精确控制风扇的启停,在有效排出箱体内湿热空气的同时,降低了干衣机的能耗,提高了用户使用的满意度。

实施例七
如图4所示,本实施例提供的干衣机的控制方法包括以下步骤:
步骤一、获取烘干时长td和环境温度Ti,判断烘干时长td是否大于预设烘 干时间。
示例性地,在本实施例中,根据待烘干衣物的重量和选定的烘干的程序确定烘干时长td。用户根据衣物的材质选择相应的烘干程序,衣物的材质可以为棉麻、丝绸、毛衣、羽绒等,不同的材质对应不同的烘干程序,烘干时长也不同,避免衣物烘不干或者过烘。将待烘干衣物放置于干衣机的滚筒内,通过电机称重的方式获取待烘干衣物的重量,由于电机称重的方式为常规技术,在此不再详细介绍。
环境温度Ti即为干衣机所处环境的温度,一般情况下在干衣机进行烘干工作前,冷凝器出口温度和压缩机排气口的温度与环境温度基本相同,并且冷凝器出口处和压缩机排气口处会设置温度传感器,所以在采集外部环境温度时,无需在干衣机上额外设置温度采集的传感器,将冷凝器出口处的温度或者压缩机排气口处的温度作为环境温度Ti即可。
在本实施例中,在确定完烘干时长td后,判断烘干时长td是否大于预设烘干时间,若是烘干时长td小于或等于预设烘干时间,则干衣机的工作时长比较短,不会产生大量的湿热空气泄漏到箱体1内,为了降低能耗,选择不启动风扇3。可以将预设烘干时间设定为40min,在此不作限定。
步骤二,响应于烘干时长td大于预设烘干时间,判断环境温度Ti是否小于预设环温值T。
示例性地,环境温度低,湿热空气更容易冷凝,环境温度高,湿热空气则不容易冷凝,因此,在烘干时长td大于预设烘干时间后,则再根据环境温度Ti确定是否需要开启风扇3,提高了风扇3控制的精确性。
步骤三、响应于环境温度Ti小于预设环温值,需要开启风扇3。
在本实施例中,预设环温值可设定为15℃,在环境温度Ti大于或等于预设环温值时,外界温度高,箱体1内的湿热空气不容易冷凝,因此,则不需要开启风扇3,以降低干衣机的能耗。
步骤四、根据烘干时长td确定风扇3开启的时间节点,并根据环境温度Ti 确定风扇3的工作模式。
在本实施例中,烘干时长td大于预设烘干时间,若是预设烘干时间设定为40min,则在干衣机工作20min-30min后启动风扇3,通常情况下干衣机的热泵系统升温需要20min-30min,在热泵系统升温达到烘干温度后,滚筒内的湿度变大,泄露的湿热空气也会增多,所以在干衣机工作的20min-30min后启动风扇3。
在本实施例中,预设环温值设定为第一预设环温值Ti1,将小于第一预设环温值Ti1的温度值划分为三个温度区域,在每个温度区域下对风扇3的控制方式不同。响应于环境温度Ti小于第一预设环温值Ti1且大于等于第二预设环温值Ti2,风扇3以启动和停止交替的方式工作,且每次启动的工作时长tw和每次停止的停止时长ts的总和为第一预设时间t1;响应于环境温度Ti小于第二预设环温值Ti2且大于等于第三预设环温值Ti3,风扇3以启动和停止交替的方式工作,且每次启动的工作时长tw和每次停止的停止时长ts的总和为第二预设时间t2;响应于环境温度Ti小于第三预设环温值Ti3,风扇3一直启动;其中,Ti3<Ti2<Ti1,t2<t1。
示例性的,第一预设环温值Ti1可设定为15℃,将低于15℃的温度划分成三个区间,第二预设环温值Ti2设定为10℃,第三预设环温值Ti3设定为5℃,在环境温度Ti大于等于10℃且小于15℃时,箱体1内会出现轻微的冷凝水,将风扇3以启动和停止交替的方式工作,在排出湿热空气的同时降低能耗。在环境温度Ti大于等于5℃且小于10℃时,箱体1内会出现中度冷凝水,风扇3可选以启动和停止交替的方式工作,每次启动和每次停止设定为风扇3运转的一个循环,在该温度划分方式下,风扇3的一个循环的第二预设时间t2小于第一预设时间t1,例如第一预设时间t1设定为10min,第二预设时间t2设定为4min,以增加风扇3运行的频率,加快湿热空气的排出。在环境温度Ti小于5℃时,箱体1内会出现重度冷凝水,风扇3需要一直打开,以尽快排出箱体1内的湿热空气,避免冷凝。
上述风扇每次启动和每次停止的时间可以根据实施例二至实施例六中的任 一个方式进行确定,在此不再详细赘述。
步骤五、烘干开始,实时检测衣物含水率,在烘干时长达到时间节点时,开启风扇3。
在本实施例中,干衣机内设置有用于检测衣物含水率的湿度传感器,在干衣机烘干开始后,湿度传感器实时检测衣物含水率。风扇3在启动起初按照步骤四设定的工作模式进行工作。
步骤六、根据检测的衣物含水率实时调整风扇3第一次启动的工作时长tw并作为新的工作时长tw。
随着衣物含水率的下降,烘干产生的湿热空气也会减少,进而泄露的湿热空气也会减少,随着湿热空气的减少,可以随之降低风扇3每次启动的工作时长tw,以降低能耗。
在本实施例中,以步骤四中确定的工作时长tw为风扇3第一次启动的工作时长tw。示例性地,获取待烘干衣物的初始含水率,将初始含水率与设定的烘干完后衣物需要达到的最终含水率之间的数值划分成多个区间,将每个区间的最小值与最大值的比值作为该区间的比例系数a。将风扇3的第一次启动的工作时长tw与第一预设时间t1或第二预设时间t2的比值再乘以比例系数a,作为每个区间对应的风扇3的工作时长tw的占比。实时检测衣物含水率,确定衣物含水率所在区间,获取与该区间对应的风扇3的工作时长tw的占比,并调整风扇3的工作时长tw。使用该方式调整风扇3的工作时间,具有针对性,调整精确性高。上述的衣物的初始含水率是在干衣机启动前通过湿度传感器检测到的数值,最终含水率是在干衣机工作前用户会选择所需要的烘干程度,根据用户的设定确定最终含水率。
示例性的,设定衣物的初始含水率为65%,最终含水率为5%,且划分为5%-15%、15%-25%、25%-35%、35%-45%、45%-55%和55%-65%,计算每个区间的最小值与最大值的比值作为比例系数a,风扇3第一次启动的工作时长tw为4min,第一预设时间t1为10min,在获取衣物含水率,确定衣物含水率所 在区间后,计算与该区间对应的工作时长tw的占比,然后调整风扇3新的工作时长tw。
在另一实施例中,以步骤四中确定的工作时长tw为风扇3第一次启动的工作时长tw。示例性地,将衣物含水率10%-100%的范围划分成多个区间,且每个区间对应设定比例系数为a,示例性的,区间100%-80%,对应的比例系数a为1.2,区间80%-60%,对应的比例系数a为1.1,区间60%-40%,对应的比例系统a为1,区间40%-20%,对应的比例系数a为0.9,区间20%-10%,对应的比例系数为0.8。区间的划分以及对应的比例系数a的设定是在干衣机出厂前设定好的,示例性地划分方式以及比例系数a的设定在此不作限定。
将风扇3的第一次启动的工作时长tw与第一预设时间t1或第二预设时间t2的比值再乘以上述的比例系数a,作为每个区间对应的风扇3的工作时长tw的占比。实时检测衣物含水率,确定衣物含水率所在区间,获取与该区间对应的风扇3的工作时长tw的占比,并调整风扇3的工作时长tw。使用该方式调整风扇3的工作时间,具有针对性,调整精确性高。
步骤七、响应于衣物含水率小于预设含水率,关闭风扇3。
在本实施例中,一般衣物含水率低于20%后,泄露的湿热空气比较少,可以关闭风扇3,降低能耗,因此通过衣物含水率确定风扇3关闭的时间点。
