本申请涉及干燥设备的技术领域，特别涉及一种干燥设备和控制方法。
背景技术
干燥设备能够输出加热气流，加速目标物的水分蒸发以实现干燥的目的。例如人在洗发之后，使用吹风机用热风吹干头发。
现有技术中的干燥设备中一般通过风温反馈的方式进行温控，即在出风口附近设置温度传感器采集风温，然后根据采集到的风温调节发热功率。这种温度控制的方式至少存在以下缺点：
(1)由于温控过程需要采集已经加热的气流的温度作为反馈调节的依据，使得温控存在滞后性，尤其干燥设备初始风温过高时，即使后续能够将风温调节降低，但已经输出的高温气流仍然有可能烫伤用户。
(2)受限于安装空间、电路设计等因素，现有技术中一般采用热敏电阻(NTC)作为检测风温的元件。热敏电阻的电阻与温度变化是非线性的，并且在高温区间(例如100℃以上)检测精度还会大幅下降，热敏电阻自身也具有安装误差，这些原因共同导致热敏电阻检测精度较差，只能给出大致的风温区间。因此，现有技术中对风温的控制仅限于设置高温阈值以避免风温过高，而不能精确控制实现某特定风温。

如图1和图4所示，本申请的实施方式中提供了一种干燥设备10，包括风力组件11、加热组件12、气压模块13和主控模块14。
风力组件11可包括电机和叶轮。风力组件11在运行时，由电机驱动叶轮转动，转动的叶轮对空气做功而使空气流动形成气流(气流方向如图4中箭头所示)。
加热组件12可包括一组或多组电热丝、电热片等结构。向加热组件12输入电流后，加 热组件12向外散热量发至附近的空气中，使空气被加热升温。将加热组件12至少部分设置在风力组件11形成的气流中，加热组件12产生的热量对流经的空气，从而使干燥设备10能够输出热气流对目标物进行干燥。
气压模块13是一种用于获取气体压强的结构。
在某些实施方式中，气压模块13自身可直接检测获得气压，例如气压模块13为气压传感器(或称海拔传感器、高度传感器)、气压计等。将气压模块13设置在非密闭空间中时，通过与空气接触能够检测获得所在位置的环境气压。
在某些实施方式中，气压模块13亦可为GPS模块，能够通过GPS信号获所在位置的海拔高度，根据海报高度换算后得到环境气压。亦或者，通过GPS信号获得所在位置，例如所在位置为北京市，根据预设的地图数据查询得到北京市的环境气压。
在某些实施方式中，气压模块13也可与其他结构通信获得环境气压。例如，干燥设备10能够与手机、平板电脑等智能终端通过蓝牙、wifi等方式建立通信，气压模块13从智能终端上直接获得所在位置的环境气压。亦或者气压模块13从智能终端上获得所在位置，根据预设的地图数据查询得到所在位置的环境气压。亦或者，气压模块13直接与相关的气压计进行通信获得环境气压。
在某些实施方式中，气压模块13也可与网络连接后获得环境气压。例如干燥设备10本身能够通过wifi或移动网络接入互联网，通过网络定位其位置后，根据预设的地图数据查询得到所在位置的环境气压。亦或者，干燥设备10接入网络后，气压模块13能够接收到从服务器端发送的环境气压信息。
在某些实施方式中，气压模块13也可以为例如按键、触摸屏等输入模块，用户自行查询环境气压后通过输入模块输入环境气压值。
在某些实施方式中，也可按批次对干燥设备12的气压模块13预标定环境气压，气压模块13仅作为存储装置，存储预标定的环境气压。在销售网络中出售干燥设备12时，将预标定的环境气压运送至对应的地区进行售卖，用户在当地购买的干燥设备12中，已经标定了对应当地的环境气压。
以上列举了气压模块13的各种实施方式，下文中如无特别说明，气压模块13指气压传感器(或称海拔传感器、高度传感器)，直接与空气接触并检测获得环境气压。
主控模块14是一种能够进行数据运算的电学结构，例如MCU(单片机)、CPU(中央处理器)等。在干燥设备10运行时，主控模块14能够从气压模块13获得环境气压，并且控制干燥设备10的控制参数，控制参数具体包含风力组件11中电机的转速和/或加热组件12的功率值。通过改变控制参数，能够改变风力组件11输出气流的风速和/或加热组件12的发热量，也即改变干燥设备10的风温和风速。
相应地，如图1和图7所示，本申请的某些实施方式中提供了一种控制方法，用于控制上述的干燥设备10，包括以下步骤：
S10通过气压模块13获取环境气压；
环境气压由气压模块13获取，指的是干燥设备10当前所处的开放环境的气压值，也即用户在使用干燥设备10时所处地区的气压值。气压模块13获取环境气压的方式可参考前文中列举的多种实施方式，不在重复。
S20根据环境气压控制风力组件11和/或加热组件12的运行。
主控模块14以环境气压作为改变控制参数的依据之一，根据不同的环境气压相应地改变控制参数，例如增加或减少加热组件12的功率值、增加或减少风力组件11的转速，从而使干燥设备10的运行能够根据环境气压的变化而调整。
上述实施方式的干燥设备10和控制方法中，主控模块14通过检测环境气压的变化对应改变干燥设备10的控制参数，从而使处于不同海拔地区的用户使用干燥设备10时能够有相似且符合设计预期的使用体验。尤其是，还能够避免由于气压变化导致的风温过高、干燥速度过慢等问题，具体的控制过程将会在下文中详述。
在某些实施方式中，如图7和图8所示，在步骤S20中，根据环境气压控制加热组件12和/风力组件11的运行，具体包括：
S21确定工作模式。
干燥设备10一般预设有一个或多个工作模式，各工作模式具有不同的设计目的，对应不同的控制参数。
例如干燥设备10为吹风机，可按照吹发速度预设三个工作模式：冷风档、中热档、高热档；亦或者按照干燥时间预设三个工作模式：低速挡、中速档、高速档。用户开启并使用干燥设备10时，干燥设备10必然处于某一个工作模式中。在干燥设备10的设计过程中，根据工作模式的设计目的确定所需的风速、风温，并且对加热组件12和/风力组件11进行标定确定该工作模式的控制参数。具体地，控制参数包括风力组件11的转速和/或加热组件12的功率值。干燥设备10在不同的工作模式中时，主控模块14按照对应的控制参数控制风力组件11和/或加热组件12的运行。
容易理解的是，在某些实施方式中，干燥设备10可能没有多个工作模式，例如干燥设备10为干手机，其只有开启和关闭两种状态。干手机在开启运行时的风速、风温也会在前期设计过程中确定，并且标定了对应控制参数，亦可理解为其工作模式即指干手机的开启的状态。
S22获取预设功率，预设功率为干燥设备10在预设气压中以工作模式运行时，加热组件12的功率值。
在干燥设备10的设计过程中，基于预设气压对各个工作模式中的运行参数进行了标定，其中至少包含了加热组件12的功率值，即对应预设气压的预设功率。
例如，干燥设备10的一个工作模式的设计目的是输出风温为60℃的气流，在预设气压中通过模拟、实验测试等方式确定了该工作模式中加热组件12的预设功率为W 1。即表明，在预设气压环境下，干燥设备10在该工作模式中输出的气流风温为60℃时，加热组件12的功率值为预设功率W 1。
S23根据环境气压和预设气压的关系，基于预设功率得到控制功率。
用户在不同地区使用干燥设备10时，环境气压和预设气压可能存在差异，例如环境气压大于预设气压，或者环境气压小于预设气压。在这些情况中，如果主控模块14依然采用预设功率控制加热组件12，会因气压变化而导致实际的风温变化，从而无法实现该工作模式的设计目的。因此，主控模块14需要根据环境气压和预设气压的关系对预设功率进行调整而得到控制功率，以使干燥设备10在不同环境气压中以同一工作模式运行时，都能够实现与预设气压中相同的设计目的。
容易理解的是，如果环境气压和预设气压相同(二者差值的绝对值小于阈值，即可认为二者相同)，则主控模块14直接以预设功率为控制功率即可。
S24根据控制功率控制加热组件12的运行。
主控模块14以适应当前环境气压的控制功率控制加热组件12的运行，干燥设备10在对应工作模式运行时即可实现与预设气压中相同的设计目的。
在上述实施方式的控制方法中，干燥设备10的设计过程中在预设气压标定了各工作模式的控制参数，亦可理解为，干燥设备10中预存的相关数据中包含了控制参数以及与控制参数对应的预设气压。在干燥设备10的使用过程中，主控模块14根据实际检测到的环境气压和预设气压的关系，基于预设功率得到适应环境气压的控制功率。
换言之，干燥设备10的控制过程中引入了环境气压作为控制依据之一，使得干燥设备10在各种环境气压中适应性调整运行参数，从而实现用户在任意地区使用干燥设备10的同一工作模式时，干燥设备10都能够实现该工作模式的设计目的，并且用户的使用体验也大致相同。
如图9所示，在某些实施方式的控制方法中，不同工作模式具有不同的风温，风温用于表征干燥设备10输出气流的温度。
干燥设备10多个工作模式的设计目的为输出气流具有不同的风温。在一个具体的实施例中，根据风温的不同预设了三个工作模式：冷风档(风温即环境气温)、中热档(风温60℃)、高热档(风温80℃)，在说明书、包装盒、显示屏等位置告知用户此三个工作模式的风温，用户根据自身需要选取工作模式使用。在干燥设备10的设计过程中，在预设气压中对上述 的三个工作模式中加热组件12的功率值进行了标定，其中冷风档对应的预设功率为0，中热档对应的预设功率为W 1，高热档对应的预设功率为W 2。即可理解为，在预设气压中，主控模块14以预设功率W 1控制加热组件12运行时，干燥设备10输出气流的风温为60℃，主控模块14以预设功率W 2控制加热组件12运行时，干燥设备10输出气流的风温为80℃。用户在使用干燥设备10时，各个工作模式中的实际风温越接近上述值，则用户的使用体验越佳。反之，如果不同地区的用户使用干燥设备10时，各个工作模式中的风温偏离上述值，用户会感觉到干燥设备10的实际风温与宣称的风温明显存在差别，从而带来较差的使用体验。
为此，在步骤S23中，基于预设功率得到控制功率，具体包括：
S231若环境气压大于预设气压，则基于预设功率增加以得到控制功率；
S232若环境气压小于预设气压，则基于预设功率减少以得到控制功率。
根据相关气体方程可知，环境气压的变化会影响干燥设备10输出气流的风温，具体原理为：在不同环境气压下，同体积气体所包含气态物质的总质量不同。向同体积气体输入相同总热量时，如果气体包含了较多质量的气态物质，则气体被加热后升温幅度较小；如果气体包含了较少质量的气态物质，则气体被加热后升温幅度较大。
例如，在环境气压为P 1的地区A使用干燥设备10时，在单位时间内，干燥设备10输出气流的总体积为S，加热组件12的功率值为W a，干燥设备10输出气流的风温为T 1。而在环境气压为P 2(P 2<P 1)的地区B使用干燥设备10时,保持相同的控制参数，同样在单位时间输出总体积为S的气流，加热组件12的发热功率也为W a，干燥设备10输出气流的风温为T 2。
由于两个地区的环境气压不同，在地区A，体积为S的气体中包含气态物质的质量较多；在地区B，体积为S的气体中包含气态物质的质量较少。因此，用户在这两个地区使用干燥设备10时，在加热组件12功率值W a不变的前提下，单位时间内加热组件12向体积为S的气体输入的总热量相同，但由于所包含的气态物质的质量不同，会导致风温T 1<风温T 2。
也即，用户在不同地区使用干燥设备10时，即使干燥设备10的运行参数完全相同，也可能会感受到不同的风温。具体为，环境气压越低则风温越高，环境气压越高则风温越低。
风温不仅会影响用户使用的体感，过高的风温还可能烫伤皮肤或引燃易燃物。如果在地区A完成干燥设备10的设计和生产，在风温最高的工作模式中，风温为略低于可能烫伤皮肤或引燃易燃物的温度。如果不考虑环境气压对风温的影响，则用户在地区B使用干燥设备10的该工作模式时，输出气流的实际风温会超出上述温度，从而造成高温危险。
基于上述原理可知，在控制参数保持不变的前提下，干燥设备10在气压较大的环境中输出的风温会下降，在气压较小的环境中输出的风温会上升。为了在同一个工作模式中，干燥设备10位于任意环境气压状态下输出的气流都具有相同的风温，本申请的上述实施方式 中，在环境气压大于预设气压时，则基于预设功率增加以得到控制功率，从而增加加热组件12对气流的输入热量，起到增加实际风温的目的。同理，若环境气压小于预设气压，则基于预设功率减少以得到控制功率，从而减少加热组件12对气流的输入热量，起到减少实际风温的目的。如此能够实现对风温的精确控制，位于任何地区的用户在使用干燥设备10的相同工作模式时，感受到的气流具有相同的风温，且该风温符合干燥设备10该工作模式所标称的风温，从而给用户带来较佳的使用体验。
尤其是，在较低环境气压地区使用时，用户选择干燥设备10最高风温的工作模式时，如不考虑气压对风温的影响，则可能出现干燥设备10风温过高的危险。虽然现有技术中能够通过检测风温来调节对气流的加热功率，但这种调节方式对风温的调节具有滞后性，无法避免初始风温过高导致的危险。而本申请上述实施方式中的控制方法，在检测到环境气压较低时直接降低了加热组件12的功率值，从而彻底避免了初始风温过高的危险。同理，在较高环境气压地区使用时，本申请上述实施方式中的控制方法亦可根据环境气压提高加热组件12的功率值，从而使其输出气流的风温不会过低，而同等情况中现有技术的干燥设备10输出气流的风温较低，可能使用户感觉到寒冷。
如图10所示，在某些实施方式的控制方法中，不同工作模式具有不同的干燥时间，干燥时间用于表征干燥设备10将目标物从第一含水量干燥至第二含水量的耗时。
例如干燥设备10为吹风机，选取的目标物为中等长度的头发(长度大致为30cm左右)。一般而言，头发完全沾湿并擦去表面水珠的状态下，水分重量占头发总重量百分比大致为30％，头发大致吹干的状态下，水分重量占头发总重量百分比大致为15％。将目标物(头发)的第一含水量设为30％，第二含水量设为15％，干燥时间即干燥设备10将头发从含水量30％的状态干燥至含水量15％的状态所消耗的时间。
多个工作模式的设计目的为对应不同的干燥时间，例如预设三个工作模式：慢速档(干燥时间15分钟)、中速档(干燥时间10分钟)、高速档(干燥时间7分钟)，在说明书、包装盒、显示屏等位置告知用户此三个工作模式的干燥时间。用户根据需要选择工作模式吹干头发，并且使用时用户期待能够以对应的干燥时间完成吹发过程，实际吹发耗时越接近工作模式对应的干燥时间，则用户体验越佳。反之，如果不同地区的用户使用干燥设备10时，各个工作模式中干燥设备10完成吹发过程耗时与宣称的干燥时间存在明显差别，会带来较差的使用体验。
需要说明的是，在吹发过程中干燥时间越短则表明头发失水速度越快，头发越容易出现过度失水、高温损伤发质等情况。基于不同的发质差别和使用习惯，不同的用户在使用干燥设备10对头发进行干燥时，会倾向于选择不同的干燥时间。例如，短发或对发质不敏感的用户倾向于快速吹干以节省时间，倾向于选择干燥时间最短的工作模式。而中长发或对发质 敏感程度高的用户倾向于慢速吹干，倾向于选择干燥时间较长的工作模式。多个工作模式的设计目的即为了满足这些不同用户的使用需要。
在步骤S23中，基于预设功率得到控制功率，包括：
S233若环境气压大于预设气压，则基于预设功率减少以得到控制功率；
S234若环境气压小于预设气压，则基于预设功率增加以得到控制功率。
根据相关气体方程可知，在不同环境气压下同体积气体所包含气态物质的总质量不同，而气体中气态物质的总质量与其吸水能力呈正比。换言之，对于同体积的气体，在环境气压较大时，其吸水能力较强，因此对目标物的干燥效率较高；而在环境气压较小时，其吸水能力较若，因此对目标物的干燥效率较低。
例如，在环境气压为P 1的地区A使用干燥设备10时，在单位时间内干燥设备10输出气流的总体积为S，加热组件12的功率值为W b，中等长度的湿头发从含水量30％干燥至含水量15％所消耗的时间为干燥时间t 1。而在环境气压为P 2(P 2<P 1)的地区B使用干燥设备10时,在单位时间内干燥设备10同样输出气流的总体积为S，加热组件12的发热功率也为W b，中等长度的湿头发从含水量30％干燥至含水量15％所消耗的时间为干燥时间为t 2。
由于两个地区的环境气压不同，在地区A，体积为S的气体中包含气态物质的质量较多，吸水能力更强；在地区B，体积为S的气体中包含气态物质的质量较少，吸水能力弱。因此，用户在这两个地区使用干燥设备10时，在加热组件12功率值W b不变的前提下，由于气态物质的质量不同而导致吸水能力差异，会出现干燥时间为t 1>干燥时间为t 2。
也即，用户在不同地区使用干燥设备10时，即使干燥设备10的控制参数完全相同，也可能会感受到不同的干燥时间。具体为，环境气压越低则干燥时间越长，环境气压越高则干燥时间越短。
基于上述原理可知，在控制参数保持不变的前提下，干燥设备10在气压较大的环境中干燥时间会减少，在气压较小的干燥时间会增加。为了在同一个工作模式中，干燥设备10位于任意环境气压状态下都具有相同的干燥时间，本申请的上述实施方式中，在环境气压大于预设气压时，则基于预设功率减少以得到控制功率，从而起到增加干燥时间的目的。同理，若环境气压小于预设气压，则基于预设功率增加以得到控制功率，从而起到减少干燥时间的目的。如此能够实现对干燥时间的精确控制，位于任何地区的用户在使用干燥设备10的相同工作模式时，完成吹发过程所耗费的干燥时间都大致相同，且干燥时间符合用户对干燥设备10该工作模式所标称的干燥时间，从而给用户带来较佳的使用体验。
需要指出的是，上述的多个实施方式中，各种工作模式之间并非互斥。例如在某些实施方式中，干燥设备10具有三个工作模式：冷风档(输出常温气流)、高速档(干燥时间7分钟)、高温档(风温80℃)，用户在选取不同工作模式后，按照前述的控制方法中对应的步 骤得到对应的控制功率。在另一些实施方式中，工作模式的设计目的也可结合前述两种方式，例如工作模式为：护发档，该档位的设计目的为兼顾快速吹干和减少对发质的损坏，其控制逻辑为，第一阶段为持续输出t1时间风温80℃的气流，第二阶段以t2时间完成干燥过程，则在上述两个阶段中，亦可根据前述的实施方式采用不同的控制逻辑得到对应的控制功率。
如图11所示，在某些实施方式的控制方法中，在步骤S20中，即根据环境气压控制风力组件11和/或加热组件12的运行，还包括：
S235若控制功率大于加热组件12的功率上限；
在前述的某些实施方式中基于预设功率增加后得到控制功率，如果预设功率本身已经是一个接近加热组件12功率上限的功率值(例如在最高风温的工作模式中)，进一步增加后所得到的控制功率有可能会超出加热组件12的功率上限，加热组件12无法以该控制功率运行，从而导致干燥设备10不能实现工作模式的设计目的，例如在气压较高的地区无法达到对应的风温或干燥时间。
S236获取工作模式中的预设转速，预设转速为干燥设备10在预设气压中以工作模式运行时，风力组件11的转速。
干燥设备10的设计过程中，在预设气压中，标定的各工作模式的控制参数包含了预设功率和预设风速。也即，在预设气压中，主控模块14按照预设功率控制发热组件运行，按照预设转速控制风力组件11运行，干燥设备10即可实现对应工作模式的设计目的。
S237基于预设转速减少以得到控制转速。
根据相关气体方程可知，在气压不变的前提下，风温与气体体积也相关。例如加热组件12的功率值为W c，风力组件11在单位时间内形成气流的气体体积为S 1，对应的风温为T c1。如果保持加热组件12的功率值为W c不变，减少风力组件11的转速使其在单位时间内形成气流的气体体积为S 2，对应风温为T c2。由于气体体积S 2<气体体积S 1，因此在输入总热量相同的前提下，会导致风温T c2>T c1。换言之，对于干燥设备10输出气流的风温控制，既可以通过改变加热组件12的功率值实现，也可以通过改变风力组件11的转速实现。
基于上述原理，当控制功率超过加热组件12的功率上限时(例如在步骤S234、步骤S231中)，基于预设转速减少以得到控制转速，主控模块14以控制转速控制风力组件11的运行，减少单位时间内形成气流的气体体积。
S238以功率上限控制加热组件12的运行，以控制转速控制风力组件11的运行。
主控模块14以控制转速控制风力组件11运行，以功率上限控制加热组件12的运行，使得干燥设备10在该工作模式中减少输出气流的总体积，在一定程度上提高风温，间接实现控制功率所对应的理论风温或干燥时间。
在某些实施方式的控制方法中，可只设置一个预设气压和对应的一组控制参数，在获取 环境气压后，根据环境气压与预设气压差值的大小，以预设的函数计算得到对应的控制功率和/或控制转速。
在如图12所示的一些实施方式中，控制方法中预设气压的数量为多个，各个预设气压都有对应的预设功率。例如在能够改变气压的实验室中对干燥设备10的各个工作模式在不同的预设气压中进行标定。亦或者通过软件模拟、在多个海拔不同的实验室中标定等方式，在多个预设气压中对干燥设备10的各个工作模式的控制参数进行标定。
相应地，在步骤S22中，获取预设功率，包括：
S221计算环境气压与各个预设气压差值的绝对值。
S222选取绝对值最小的预设气压，以其对应的预设功率为控制功率。
在上述的实施方式中，在干燥设备10的设计过程中设置多个预设气压，覆盖人类居住的气压范围，并且分别在这些预设气压中对干燥设备10各个工作模式的控制参数进行标定。用户使用干燥设备10切换至某工作模式时，主控模块14根据实施检测的环境气压，通过计算与各个预设气压插值的绝对值，选取并调用最接近的预设气压中的预设功率作为控制功率，以干燥设备10适应实际的环境气压。
在上述实施方式中，预设气压的数量越多，则理论上对干燥设备10的控制越精确，但也会带来数据量大、前期工作量大等问题。
如图13所示的另外一些实施方式中，控制方法中预设气压的数量为多个，各个预设气压都有对应的预设功率。
在步骤S22中，即获取预设功率，包括：
S223根据多个预设气压与对应预设功率获得拟合函数；
拟合是把平面上一系列的点用一条光滑的曲线连接起来，该曲线亦可用函数表示，即拟合函数。拟合函数是一种数据处理方式，以有限的预设数据建立数学模型。常用的拟合方法有如最小二乘曲线拟合法等。
例如，在干燥设备10的设计过程中，在多个预设气压中获得对应的预设功率后，在平面坐标系中以气压值为横坐标，功率值为纵坐标，绘制多个点，各点的坐标为(预设气压，预设功率)，然后以光滑曲线连接各个点获得拟合函数f(p)＝w，其中自变量p为气压值，w为对应的功率值。
S224根据拟合函数，获取环境气压对应的控制功率。
获得拟合函数后，将气压模块13测得的环境气压带入拟合函数，即可计算得到对应的控制功率。例如在用户使用干燥设备10时，气压模块13所检测到环境气压为p x，带入前述拟合函数f(p x)计算得到与环境气压p x对应的控制功率w x。
在其他的实施方式中，也可以采用插值计算的等方式获得对应的函数，根据环境气压获 得对应的控制功率。
在上述实施方式中，可减少预设气压的数量，通过函数的方式实时计算获得控制功率，数据量较小，并且前期工作量较小。
在其他的实施方式中的控制方法也可结合上述两种方式。例如在干燥设备10的设计过程中，在多个预设气压P x1、P x2、P x3……中标定对应的预设功率W x1、W x2、W x3……，干燥设备10运行时检测到环境气压P x后，通过差值的绝对值计算匹配最接近的预设气压P xn和对应的预设功率W xn，根据环境气压P x与预设气压P xn的差值，对参考预设功率W xn进行修正计算，例如按照预设的函数f(P x-P xn)计算修正值，按照修正值对参考预设功率W xn进行修正后得到控制功率W x。如此，可结合前述两种方式的优缺点，减少数据量和前期设计的工作量。
如图1和图2所示，在某些实施方式中的干燥设备10，其加热组件12包括多组发热结构121，发热结构121可以预设长度的电热丝或预设面积的电热片等结构。多组发热结构121具有相同或不同的额定功率，多组发热结构121可以采用串联或者并联的方式组合，亦或者各自分别独立。主控模块14能够通过下列两种方式中的任一种对加热组件12控制：
(1)主控模块14控制任意发热结构121的启闭。例如加热组件12包括4组完全相同的发热结构121，当主控模块14关闭其中1组发热结构121、开启剩余3组发热结构121时，则加热组件12以最大功率的75％运行。或者，加热组件12包括1组额定功率为W a的发热结构121和1组额定功率为2W a的发热结构121；主控模块14关闭一组额定功率为W a的发热结构121、开启另一组额定功率为2W a的发热结构121，加热组件12以最大功率的67％运行。
(2)主控模块14控制任意发热结构121的功率值。例如，加热组件12包括2组完全相同的发热结构121，当主控模块14控制其中1组发热结构121的功率值为其最大功率的50％，另1组发热结构121功率值为其最大功率的100％，则加热组件12以最大功率的75％运行。
主控模块14对于加热组件12的控制，也可结合上述两种方式。例如加热组件12包括完全相同的两组发热结构121，则主控模块14对加热组件12的控制方式还可以为：关闭其中一组发热结构121，另一组发热结构121的输入功率为其最大功率的50％，则加热组件12以最大功率的25％运行。
在某些实施方式中，如图1和图4所示，干燥设备10还包括壳体16，壳体16内设有气流通道164，风力组件11被配置为在气流通道164中产生气流。气流通道164是由侧壁围合而成的空间，限定了干燥设备10内部形成的气流截面大小。相应地，风力组件11中的叶轮直径略小于气流截面，以在气流通道164内对空气充分做功。结合风力组件11中叶轮转速和气流截面尺寸，即可计算出单位时间流经干燥设备10的气流体积。
气压模块13检测环境气压时需要接触外部空气，如果将气压模块13直接设置在壳体16外表面，虽然能够满足接触外部空气的要求，但破坏了干燥设备10的外观一致性，而且外露的气压模块13还存在容易损坏的风险。因此，在一些实施方式中，气压模块13设置在气流通道164中，使其能够与气流通道164中的气流接触而检测环境气压，而且气压模块13隐藏在壳体16的内部，不会影响干燥设备10外观一致性，气压模块13也不易被损坏。
在某些实施方式中，风力组件11采用的超高速电机，在运行时会在气流通道164内形成高速气流，高速气流流经气压模块13时会对其测得的环境气压造成影响，偏离实际的环境气压。为此，在某些实施方式中的控制方法，在步骤S10之前，即通过气压模块13获取环境气压之前，还包括：
在风力组件11未运行或运行时间小于预设值的状态下，通过气压模块13获取环境气压。
在某些实施方式中，在风力组件11未运行的状态下，气流通道164中没有高速气流，气压模块13能够精确的检测获取环境气压。
在某些实施方式中，可在干燥设备10启动后设置一个较短的延迟时间，例如0.1秒、0.3秒、0.5秒、0.8秒、1秒、1.5秒、2秒、3秒等，在经过延迟时间后风力组件11开始运行，也即延迟了干燥设备10启动后出风的时间。在此延迟时间内，气流通道164中尚未产生气流，气压模块13也能够准确的检测到环境气压。
在某些实施方式中，将气压模块13的检测时间设定在干燥设备10启动后一个较短的预设时间内，例如预设时间设置为干燥设备10启动后0.1秒、0.3秒、0.5秒、0.8秒、1秒、1.5秒、2秒、3秒等。在预设时间内，风力组件11形成的高速气流尚未达到最大风速，对环境气压的影响较小。因此气压模块13在该预设时间段内检测环境气压时，能够避免受高速气流影响，从而测得较为精确的环境气压。
如图1、图2和图4所示，在某些实施方式中，加热组件12包括第一组件124和第二组件123，并且，沿着气流的方向(图4中箭头方向)，第一组件124位于风力组件11的上游，第二组件123位于风力组件11的下游。第一组件124可以为一个或多个前述的发热结构121通过串联和/或并联构成，第二组件123也可以为一个或多个前述的发热结构121通过串联和/或并联构成。第一组件124和第二组件123的结构、发热功率可以相同，也可以不同，二者主要差别在于在气流中相对风力组件11的位置。容易理解的是，主控模块14对加热组件12的控制，也可包括控制第一组件124、第二组件123各自的启闭或输入功率。在第一组件124和第二组件123同时工作时，相当于在气流的两个位置对空气进行加热，因而使加热组件12具有更大的换热面积、更高的加热效率。
然而，在第一组件124工作时，其所加热的气流会经过风力组件11，从而导致风力组件11运行在被热气流中，可能会影响风力组件11的性能和使用寿命。因此，在主控模块14 按照控制功率对加热组件12控制时，如果控制功率低于第一阈值(第一阈值大致相当于第二组件123的最大功率)时，控制功率可完全由第二组件123实现。此时，主控模块14的控制策略为关闭第一组件124，只开启第二组件123并控制其运行达到控制功率。如此，能够使得在某些工况中主控模块14优先关闭第一组件124，以使这些工况下风力组件11不会工作在被加热气流中，以延长风力组件11的使用寿命。
在更具体的实施方式中，如图5或图6所示，干燥设备10的壳体16上具有第一进风口161、第二进风口162、出风口163。气流通道164包括第一风道164a和第二风道164b，第一风道164a连接在第一进风口161、出风口163之间。风力组件11设置在第一风道164a内，运行时直接在第一风道164a内产生气流，气流从第一进风口161进入壳体16内并沿着第一风道164a流动，从出风口163流出壳体16。
在图5所示的实施方式中，第二风道164b的上游连接至第二进风口162，下游连接至第一风道164a。风力组件11在第一风道164a内产生气流后，会在第二风道164b的下游形成负压，从而将壳体16外部的气体从第二进风口162吸入并沿着第二风道164b流动，最终汇入第一风道164a。
在图6所示的实施方式中，第二风道164b的上游连接至第二进风口162，下游连接至出风口163，风力组件11在第一风道164a内产生气流后，也会在出风口163形成负压，从而将壳体16外部的气体从第二进风口162吸入后沿着第二风道164b流动，最终从出风口163流出。
图5、图6所示的实施方式中，由于风力组件11设置在第一风道164a中，第二风道164b内的空气间接受到风力组件11影响而形成气流，因此第二风道164b的气流流速小于第一风道164a的气流流速。
如图1、图5、图6所示，在某些实施方式中的干燥设备10，气压模块13设置在第二风道164b中，由于第二风道164b气流的流速较小，对环境气压的影响也较小，从使气压模块13能够到较为精确的检测到环境气压。在某些实施方式中，也可将气压模块13设置在第一风道164a中，由于第一风道164a气流的流速较大，为了流速对检测到的环境气压的影响，可参考前文的控制方法，即在风力组件11未运行或运行时间小于预设值的状态下，通过气压模块13获取环境气压。
容易理解的是，在某些实施方式中，第二风道164b中的气流也可能对气压造成影响，从而使气压模块13检测到的环境气压存在误差。同样可采用与前述相似的方式，例如在风力组件11未运行或运行时间小于预设值的状态下检测等，从而避免高速气流对气压模块13检测准确度的影响。
如图1、图5、图6所示，在更具体的实施方式中，干燥设备10还包括设置在第二风道 164b中的控制电路15。气压模块13、主控模块14均设置在控制电路15上，并且控制电路15电连接于风力组件11、加热组件12。控制电路15构成干燥设备10内部主要的电路结构。在干燥设备10运行时，第二风道164b中的气流流经整个控制电路15，除了使气压模块13更加精确的检测到环境气压以外，气流还能够对控制电路15起到散热作用，避免控制电路15过热。由于第二风道164b中的气流流速相较第一风道164a中的气流更低，因此控制电路15设置在第二风道164b中不会产生明显的风噪。
如图3所示，在某些实施方式中，干燥设备10还包括能够输出红外辐射的辐射组件17，辐射组件17与主控模块14连接，且主控模块14被配置为能够根据环境气压调整辐射组件17的运行功率。辐射组件17在输入电流后能够产生预设波段的红外辐射，直接作用于目标物进行干燥。
相应地，在本申请的某些实施方式中的控制方法，还包括以下步骤：
确定环境气压是否低于阈值。
由于辐射组件17在工作时自身也会发热。根据前述的环境气压对风温的影响可知，在环境气压较低的环境中，辐射组件17更容易将附近的气流加热较高的温度，使得辐射组件17的散热效率降低。不仅辐射组件17容易过热，还有可能提进一步使得整个干燥设备10过热，存在烫伤用户的可能性。而且，根据黑体辐射的原理，辐射组件17运行在较高温度时会还可能发生光谱漂移，使发出的红外辐射波长发生变化，而影响干燥时间。因此，预先通过模拟仿真、实验测试等方式，确定辐射组件17出现散热效率过低的环境气压，存储为阈值。
若低于阈值，则降低辐射组件17的运行功率。
干燥设备10运行过程中，当气压模块13检测到的环境气压低于阈值时，主控模块14对应减少辐射组件17当前的运行功率。如此，一方面避免了辐射组件17过热、干燥设备10整体发烫，另一方面也能使辐射组件17保持在适合工作温度区间，从而保证辐射组件17的发出预设波长的红外辐射。
容易理解的是，与上述的辐射组件17类似，在其他实施方式中干燥设备10还可设有其他耗电组件，例如负离子组件、护发精油组件等，这些耗电组件本身运行时也必然伴随发热，从而提高整个干燥设备10的发热量。由于在环境气压较低时，干燥设备10散热效率会下降。因此，主控模块14需要根据环境气压调整干燥设备10上所有耗电组件的功率，以保证整个干燥设备10的散热效率，避免壳体16过热。
本申请的某些实施方式中还提供一种可读存储介质，可读存储介质存储有程序，程序被处理器执行时实现前述控制方法的各个步骤。

尽管上面已经示出和描述了本申请的实施方式，可以理解的是，上述实施方式是示例性的，不能理解为对本申请的限制，本领域的普通技术人员在本申请的范围内可以对上述实施方式进行变化、修改、替换和变型。
