具体实施方式
以下结合附图对本申请的示范性实施例做出说明，其中包括本申请实施例的各种细节以助于理解，应当将它们认为仅仅是示范性的。因此，本领域普通技术人员应当认识到，可以对这里描述的实施例做出各种改变和修改，而不会背离本申请的范围和精神。同样，为了清楚和简明，以下的描述中省略了对公知功能和结构的描述。
图1为相关技术中热泵干衣机的原理示意图。参照图1，热泵干衣机100包括箱体10、滚筒20、电机30、风机40、风道和热泵系统50，至少滚筒20、电机30和热泵系统50设置在箱体10内，箱体10对滚筒20、电机30和热泵系统50形成防护。其中，电机30用于驱动滚筒20转动，滚筒20用于盛装衣物，滚筒20的筒底设置有干热风进口(图1中位于滚筒20的右端)，滚筒20的筒口设置有湿热风出口(图1中位于滚筒20的左端)，风道与滚筒20连通，风机40用于驱动空气在风道和滚筒20内循环流动，热泵系统50够用于对滚筒20内的衣物进行烘干。
热泵系统50包括压缩机51、冷凝器52以及蒸发器53，滚筒20的湿热风出口与蒸发器53的进气口连通，压缩机51位于蒸发器53的出气口与冷凝器52的进气口之间，冷凝 器52的出气口与滚筒20的干热风进口连通，蒸发器53、压缩机51和冷凝器52依次相连并构成用于供制冷剂循环流动的热泵回路。
热泵干衣机100的干衣过程为：从滚筒20的湿热风出口进入风道内的湿热空气从蒸发器53的进气口进入蒸发器53内，并与蒸发器53的制冷剂进行热交换，湿热空气的热量交换给蒸发器53内的制冷剂，使得制冷剂升温气化，湿热空气中的水汽由于温度降低而凝结成冷凝水并在重力作用下从空气中分离，失去大量水汽的干冷空气则从蒸发器53的出气口排出，随后从冷凝器52的进气口进入到冷凝器52中。
在蒸发器53内升温气化后的制冷剂在压缩机51的作用下变成高温高压气体，然后流入冷凝器52内，并与除湿后的干冷空气进行热交换，干冷空气在吸收高温高压气相制冷剂的大量热量后变成干热空气从冷凝器52的出气口排出，随后从滚筒20的干热风进口流入滚筒20内，以便对滚筒20内的衣物进行干燥。
干热空气在将湿衣物中的水气化以后变成湿热空气，随后再一次从滚筒20的湿热风出口进入风道内，从而开始下一次循环。冷凝器52内失去热量的制冷剂则流回到蒸发器53内，以便开始下一次循环。如此，最终可以实现衣物的烘干。
为了改善衣物烘干效果，热泵干衣机100还包括检测装置和与检测装置电连接的控制器，检测装置用于检测衣物的湿度，控制器根据检测装置检测到的湿度控制滚筒20的转速。当衣物湿度较大时，滚筒20的转速增大，以使衣物与热空气的接触面积增大，进而有利于提高衣物烘干效率。
但是，烘干过程中，衣物的湿度会发生很大的变化，根据衣物的湿度仅控制电机转速，此时热泵干衣机100的控制策略比较单一，热泵干衣机100无法发挥最佳效果，导致烘干效率较低且耗能较高。
有鉴于此，本申请可以考虑根据衣物的含水率来协同控制电机、风机40和加热丝60，以使电机、风机40和加热丝60的运行状态均与衣物的含水率相适应，有利于使得热泵干衣机发挥最佳效果，则热泵干衣机具有较高的烘干效率的同时耗能较低。
图2为本申请实施例提供的热泵干衣机的原理示意图，图3为本申请实施例提供的一种热泵干衣机的控制方法的流程示意图。参照图2和图3，本实施例提供一种热泵干衣机的控制方法，该控制方法主要应用于热泵干衣机100的整个烘干过程中，用于检测热泵干衣机100的滚筒20内的衣物的含水率，并根据含水率控制热泵干衣机100。
本申请实施例提供的热泵干衣机的控制方法的执行主体可以是热泵干衣机100，也可以是能够控制热泵干衣机的控制设备，例如服务器或者终端设备。下述实施例以热泵干衣机100为例，对本申请实施例提供的热泵干衣机的控制方法进行示意说明。
本实施例提供的热泵干衣机的控制方法，主要包括如下步骤：
步骤101：获取热泵干衣机的滚筒内衣物的当前含水率。
滚筒20内的衣物是待烘干衣物，含水率是指待烘干衣物中所含水分与待烘干衣物的重量之比。具体的，获取热泵干衣机100的滚筒20内衣物的当前含水率的可能实现步骤可以包括如下步骤1-步骤2：
步骤1：获取滚筒内衣物的重量以及湿度。
该步骤可通过获取模块来实现，具体的，获取模块可以包括湿度传感器和称重传感器，湿度传感器可以设置在滚筒20的内部或者滚筒20的湿热风出口处，用于采集衣物的湿度； 称重传感器可以设置在滚筒20的外壁上，用于采集滚筒20与滚筒20内待烘干衣物的总重量。其中，滚筒20的重量是常数，将称重传感器检测到的总重量减去滚筒20的重量即可得到衣物的重量。
当然，湿度传感器还可以替换为金属条电极，金属条电极用于检测衣物的阻抗值，由于衣物的阻抗值与湿度成正比，因此金属条电极也能够检测衣物的湿度。
步骤2：根据衣物的重量以及湿度，获取衣物的当前含水率。
由前文可知，含水率是指待烘干衣物中所含水分与待烘干衣物的重量之比，故将获取到衣物的湿度与衣物的重量相比，得到的比值即为衣物的当前含水率。
步骤102：根据当前含水率确定衣物的烘干阶段，其中，烘干阶段包括前期干衣阶段、中期干衣阶段和后期干衣机阶段。
可以理解，热泵干衣机100会按时间顺序依次进入前期干衣阶段、中期干衣阶段和后期干衣机阶段。前期干衣阶段时，衣物被烘干的时间较短，则衣物的含水率较高；后期干衣阶段时，衣物被烘干的时间较长，则衣物的含水率较低；衣物在中期干衣阶段时的含水率位于衣物在前期干衣阶段时的含水率和衣物在后期干衣阶段时的含水率之间。由此，烘干过程中，衣物的含水率是变化的，因此通过分析衣物的含水率，可以准确的确定衣物所处的烘干阶段。
具体而言，根据当前含水率确定衣物的烘干阶段的可能实现方式为：获取第一预设含水率和第二预设含水率；根据当前含水率、第一预设含水率和第二预设含水率，确定衣物的烘干阶段。其中，第一预设含水率大于第二预设含水率。
在一种示例中，第一预设含水率和第二预设含水率可以通过多次实验分析得到，并可以预置在热泵干衣机100的处理器中。此时，热泵干衣机100可以直接获取预设的第一预设含水率和第二预设含水率。举例而言，第一预设含水率可以为60％，第二预设含水率可以为10％。
在另一种示例中，热泵干衣机100在获取到衣物的当前含水率后，也可以通过如下步骤1-步骤3来获取第一预设含水率和第二预设含水率。
步骤1：获取热泵干衣机在历史时长内的历史数据组，历史数据组是热泵干衣机每运行一次时衣物的历史含水率和与历史含水率对应的时刻。
示例性地，在历史时长内，热泵干衣机100在烘干衣物的过程中将获取到的当前含水率上报给服务器，服务器获取到热泵干衣机100上报的含水率并将其作为历史含水率存储，与此同时，服务器记录上报的时间点，该时间点即为与历史含水率对应的时刻。
历史时长是非限制性的，比如，历史时长可以是1个月，也就是说，获取热泵干衣机100在过去一个月内运行的历史数据组。可以理解，若过去一个月内用户2次利用热泵干衣机100来烘干衣物，则服务器能够获取到2个历史数据组。
步骤2：将每个历史数据组的历史含水率按照时间顺序进行排序，获取每个历史数据组中由最初时刻经过第一预设时长所对应的第一初始含水率，获取每个历史数据组中由最初时刻经过第二预设时长的时刻所对应的第二初始含水率。其中，第一预设时长小于第二预设时长。
该步骤的目的在于通过对热泵干衣机100以往的数据进行分析，以获取热泵干衣机100烘干过程中运转第一预设时长时衣物的第一初始含水率，以及运转第二预设时长时衣物的 第二初始含水率。其中，第一预设时长可以理解为热泵干衣机100的前期干衣阶段结束所需的大体时长，第二预设时长可以理解为热泵干衣机100的中期干衣阶段结束所需的大体时长。
第一预设时长和第二预设时长可以根据实际经验进行设计，并可以通过更新热泵干衣机100的程序代码来进行预置。并且，第一预设时长以及第二预设时长与热泵干衣机100运行的总时长相关。举例而言，热泵干衣机100运行的总时长为45min时，第一预设时长可以为10min、第二预设时长可以为30min。
这里，还需说明的是，最初时刻指的是每个历史数据组中最先记载的时刻。例如，获取到的一个历史数据组按时间顺序排列后如表1所示，此时，最初时刻为15：03，以第一预设时长为10min、第二预设时长为30min为例说明，第一初始含水率即为70％，第二初始含水率即为30％。
表1
时刻 15：03 15：08 15：13 15：18 15：23
含水率 90％ 80％ 70％ 60％ 50％
时刻 15：28 15：33 15：38 15：43 15：48
含水率 40％ 30％ 20％ 10％ 2％
热泵干衣机100具有多种运行模式，例如快速烘干模式、标准烘干模式、羊毛烘干模式等，当用户选中其中一种运行模式时，热泵干衣机100执行与该运行模式对应的程序，则热泵干衣机100运行的总时长是确定的。并且，热泵干衣机100以不同的运行模式对衣物进行烘干时，其运行的总时长也不同。
因此，不同的运行模式下，热泵干衣机100的前期干衣阶段结束所需的时长以及中期干衣阶段结束所需的时长均不同，则不同运行模式所对应的第一预设时长和第二预设时长也可以不同。
进一步地，在将每个历史数据组的历史含水率按照时间顺序进行排序之前，可以先对历史数据组进行分类，具体是将热泵干衣机100以同样的运行模式运行所得到的历史数据组划分到同一类别，然后在获取第一初始含水率和第二初始含水率时，同一类别的历史数据组采用相同的第一预设时长和第二预设时长，不同类别的历史数据组采用不同的第一预设时长和第二预设时长。
步骤3：将所有第一初始含水率的平均值作为第一预设含水率，将所有第二初始含水率的平均值作为第二预设含水率。
该步骤是将热泵干衣机100在历史时长内运行了第一预设时长时衣物的含水率的平均值作为第一预设含水率，运行了第二预设时长时衣物的含水率的平均值作为第二预设含水率，上述第一预设含水率和第二预设含水率作为判断衣物的烘干阶段的参数。
如此设置，与直接预设第一预设含水率和第二预设含水率相比，本示例通过对热泵干衣机100的历史数据进行分析，以计算得出第一预设含水率和第二预设含水率，进而能够更准确的用来判断衣物的烘干阶段。
在获取第一预设含水率和第二含水率后，再根据当前含水率、第一预设含水率和第二预设含水率，确定衣物的烘干阶段。
可选的，当衣物的当前含水率大于或等于第一预设含水率时，确定衣物的烘干阶段为前期干衣阶段。
可选的，当衣物的当前含水率介于第一预设含水率与第二预设含水率之间时，确定衣物的烘干阶段为中期干衣阶段。
可选的，当衣物的当前含水率小于或等于第二预设含水率时，确定衣物的烘干阶段为后期干衣机阶段。
以第一预设含水率为60％、第二预设含水率为10％为例进行说明，当衣物的当前含水率为70％时，衣物的烘干阶段则为前期干衣机阶段；当衣物的当前含水率为40％时，衣物的烘干阶段则为中期干衣阶段；当衣物的当前含水率为10％时，衣物的烘干阶段则为后期干衣阶段。
步骤103：根据烘干阶段调整热泵干衣机的工作参数，其中，工作参数包括电机转速、风机转速和风道内的加热丝的启停状态。
需要指出的是，如图2所示，电机30仅与滚筒20传动连接，以使滚筒20能够被单独驱动。也即，本实施例中热泵干衣机100的滚筒20和风机40不是通过同一个驱动器来驱动的，这样，才能够分别调整电机转速和风机转速，进而能够分别调整滚筒20转动的速度和风道内的风速。
风道包括连通冷凝器52的出气口与滚筒20的干热风进口的第一部分A1，加热丝60位于第一部分A1风道内。从冷凝器52的出气口排出的干热空气流经加热丝60时可以进行二次加热，使得流入滚筒20内部的干热空气温度再次升高，从而加快烘干速度，提高了烘干效率。
可选的，当衣物处于前期干衣阶段时，将电机转速调整至第一电机转速区间、将风机转速调整至第一风机转速区间，并将加热丝60调整为加热状态。
可选的，当衣物处于中期干衣阶段时，将电机转速调整至第二电机转速区间、将风机转速调整至第一风机转速区间，并根据滚筒20的出风温度调整加热丝60的启停状态，第二电机转速区间中的转速大于第一电机转速区间中的转速。
可选的，当衣物处于后期干衣机阶段时，将电机转速调整至第一电机转速区间、将风机转速调整至第二风机转速区间，并将加热丝60调整为停止加热状态，第一风机转速区间中的转速大于第二风机转速区间中的转速。
本实施例对第一电机转速区间和第二电机转速区间不做限制，只要第一电机转速区间小于第二电机转速即可。并且，本实施例对第一风机转速区间和第二风机转速区间也不做限制，只要第一风机转速区间大于第二风机转速区间即可。
举例而言，第一电机转速区间可以为40rpm～60rpm，第二电机转速区间可以为60rpm～75rpm，第一风机转速区间可以为1100rpm～1400rpm，第二风机转速区间可以为700rpm～1100rpm。
结合前文描述的内容可知，衣物处于前期干衣阶段时，电机30处于相对较低的转速、风机40处于相对较高的转速。由此，衣物的湿度最高，通过将风机转速提高，以使得空气循环速度快，进而能够促使干热空气能够更快流入滚筒20，以提高衣物被烘干的效率；与此同时，因为衣物的湿度最高，所以风机40驱动的空气便能快速带走衣物上的水，故将滚筒20设置为低转速，一方面，在确保烘干效率的同时还可以避免热泵干衣机的能耗 过高，另一方面，滚筒20内的空气流通能够更顺畅，则湿热空气能够更快的排出滚筒20。并且，衣物处于前期干衣阶段时，热泵系统50的运行处于起始阶段，干热空气的温度上升较慢，通过将加热丝60调整为加热状态，可以加快温度上升的速度，有利于提高烘干效率。
衣物处于中期干衣阶段时，电机30和风机40均处于相对较高的转速。由此，衣物的湿度较高，水分子主要存在于衣物接触的位置，通过将风机转速调高，使得空气循环的速度提高，以利于提高衣物被烘干的效率；通过将电机转速提高，使得滚筒高速转动以抖散衣物，有助于使衣物分离，则干热空气能够吹至衣物之间，以使得衣物接触的位置能够变干，有利于提高衣物被烘干的效率。
衣物处于后期干衣阶段时，电机30和风机40均处于相对较低的转速。由此，衣物的湿度较低，水分子主要存在于衣物的纤维上，此时即便往滚筒内送入温度较高或者风速较大的干热空气也无法祛除衣物纤维上的水分子，故通过将风机转速和电机转速都调低，有利于在热泵系统仍然能烘干衣物同时还可以避免热泵干衣机的能耗过高。并且，衣物处于后期干衣阶段时，衣物的湿度已经大幅降低，从滚筒20的干热风进口流入滚筒20内的干热空气的温度下降幅度明显变小，使得从滚筒20的湿热风出口排出的湿热空气的温度会有明显的增加，通过将加热丝60调整为不加热状态，加热丝60不再对干热空气进行二次加热，进而有利于降低进入蒸发器53的湿热空气的温度，以利于降低压缩机51的排气温度，从而避免压缩机51高负荷工作而频繁启停。
图4为本申请实施例提供的另一种热泵干衣机的控制方法的流程示意图。参照图4，在上述实施例中，当衣物处于中期干衣阶段，根据滚筒20的出风温度调整加热丝60的启停状态的具体实现过程为：
步骤201：获取滚筒的出风温度。
具体的，风道还包括连通滚筒20的湿热风出口与蒸发器53的进气口的第二部分A2，滚筒20的湿热风出口处或者第二部分A2内设有温度传感器，温度传感器用于检测滚筒20的出风温度。
步骤202：若出风温度大于或等于第一预设温度，则将加热丝调整为停止加热状态。
步骤203：若出风温度小于或等于第二预设温度，则将加热丝调整为加热状态，第二预设温度小于第一预设温度。
示例性地，热泵干衣机100可以先将出风温度与第一预设温度进行比较，当出风温度不小于第一预设温度时，则控制加热丝60停止加热；当出风温度小于第一预设温度时，再将出风温度与第二预设温度进行比较，当出风温度不大于第二预设温度时，则控制加热丝60加热。
在其他实施例中，热泵干衣机100也可以先将出风温度与第二预设温度进行比较，若出风温度不大于第二预设温度时，则控制加热丝60加热，若出风温度大于第二预设温度，再将出风温度与第一预设温度进行比较，若出风温度不小于第一预设温度，则控制加热丝60停止加热。当然，热泵干衣机100还可以同时将出风温度与第一预设温度及第二预设温度进行比较，然后根据比较结果执行步骤202或者执行步骤203。
还可理解，若出风温度位于第二预设温度和第一预设温度之间，加热丝60可以为加热状态，或者，加热丝60也可以为停止加热状态，此时，热泵干衣机100仅依赖于热泵 系统50对衣物进行烘干。其中，第一预设温度和第二预设温度均不受限制，举例来说，第一预设温度可以为75℃，第二预设温度可以为70℃。
通过上述设置，衣物处于中期干衣阶段时，滚筒20的出风温度可以维持在第二预设温度和第一预设温度之间，以免滚筒20内的温度过高或过低。
综合上文内容，本申请实施例提供的热泵干衣机的控制方法，通过获取滚筒20内衣物的当前含水率，由当前含水率可以推断出衣物所处的烘干阶段，根据烘干阶段来调整电机转速、风机转速和加热丝的启停状态，而不仅仅是控制调节电机转速，热泵干衣机100的控制策略不单一，有利于使热泵干衣机100发挥最佳效果，从而有助于在提高热泵干衣机100的效率时还避免耗能过高。
应理解，虽然上述方法实施例均以热泵干衣机100为例进行了示例说明，但是上述方法实施例也可以由能够控制热泵干衣机的控制设备来实现。当由控制设备实现时，控制设备可以基于获取到的衣物的当前含水率进行上述处理，并控制热泵干衣机100调整相应的参数，对此不再赘述。

图7为本申请实施例提供的热泵干衣机的后视图，图8为本申请实施例提供的热泵干衣机的立体示意图。结合图2、图7和图8，本申请一个实施例提供一种热泵干衣机100，该热泵干衣机100包括箱体10、滚筒20、电机30、风机40、风道和热泵系统50，电机30与滚筒20传动连接，以驱动滚筒20在箱体10内转动，滚筒20的筒底设置有干热风进口，滚筒20的筒口设置有湿热风出口，风道与滚筒20连通，风机40用于驱动空气在风道和滚筒20内循环流动，热泵系统50够用于对滚筒20内的衣物进行烘干。
热泵系统50包括压缩机51、冷凝器52以及蒸发器53，滚筒20的湿热风出口与蒸发器53的进气口连通，压缩机51位于蒸发器53的出气口与冷凝器52的进气口之间，冷凝器52的出气口与滚筒20的干热风进口连通，蒸发器53、压缩机51和冷凝器52依次相连并构成用于供制冷剂循环流动的热泵回路。
热泵系统50可以设置在滚筒20外周的任意位置，考虑到热泵系统50重量大，热泵系统50可以设置在滚筒20的底部，避免因热泵系统50支撑不牢固而掉落。
在图2中，风道包括第一部分A1、第二部分A2和第三部分A3，第一部分A1连通冷凝器52的出气口与滚筒20的干热风进口，第二部分A2连通滚筒20的湿热风出口与蒸发器53的进气口，第三部分A3连通蒸发器53的出气口与冷凝器52的进气口。结合上述内容可知，第一部分A1、滚筒20的干热风进口、滚筒20内、滚筒20的湿热风出口、第二部分A2和第三部分A3依次连通。
该热泵干衣机100还包括加热丝60、检测装置和至少一个处理器，加热丝60设置在风道的第一部分A1内并通过电路为加热丝60供电，从冷凝器52的出气口排出的干热空气流经加热丝60时可以进行二次加热；检测装置用于获取滚筒20内衣物的当前含水率，处理器用于根据检测装置检测的当前含水率确定衣物的烘干阶段，并根据烘干阶段调整热泵干衣机100的工作参数，其中，烘干阶段包括前期干衣阶段、中期干衣阶段和后期干衣机阶段，工作参数包括电机转速、风机转速和加热丝60的启停状态。
如此设置，热泵干衣机100可以根据衣物的含水率来协同控制电机30、风机40和加热丝60，以使电机30、风机40和加热丝60的运行状态均与衣物的含水率相适应，有利于使得热泵干衣机100发挥最佳效果，则热泵干衣机100具有较高的烘干效率的同时耗能较低。
具体的，该热泵干衣机100还包括防火护板80，防火护板80与箱体10连接并共同围 成能够与第一部分A1连通的安装空间，加热丝60位于安装空间内，且加热丝60固定在防火护板80上。也就是说，防火护板80设置在第一部分A1并与箱体10连接，加热丝60固定在防火护板80上。这样，防火护板80能够起到防护作用，有利于在加热丝60过热形成火花时阻隔火花与箱体10，以免火花对箱体10进行加热而导致箱体10受热损坏。
在第一种可实现的方式中，风道的第一部分A1可以位于箱体10内。具体的，热泵干衣机100还可以包括导风板，导风板设置在箱体10内，且导风板与箱体10连接并共同围合形成第一部分A1。在该示例中，防火护板80也设置在箱体10内并与箱体10的内侧面连接。
在第二种可实现的方式中，如图7和图8所示，第一部分A1包括依次连通的第一段和第二段，第一段位于箱体10内，第二段位于箱体10外。在该示例中，防火护板80可以设置在第二段内，并与箱体10的外侧面连接。
具体而言，箱体10的后侧板11上设有与滚筒20的干热风进口正对的进风口，风机40设置在后侧板11上，热泵干衣机100包括通风罩壳70，通风罩壳70罩设在后侧板11上，且通风罩壳70与后侧板11共同限定出连通进风口与风机40的风机出口的连通风道。连通风道即为第二段，相应的，冷凝器52的出气口与风机40的风机进口之间形成第一部分A1的第一段。
热泵干衣机100工作时，风机40驱动由冷凝器52的出气口流出的干热空气从风机出口流入到通风罩壳70内，再从通风罩壳70流入到箱体10的进风口，在此期间，加热丝60对干热空气加热，使得干热空气的温度升高，之后，升温的空气从滚筒20的干热风进口流入滚筒20内。
第二种可实现的方式中，加热丝60位于箱体10外，这样，加热丝60的温度较高时，有利于避免高温对设置在箱体10内的热泵系统50的性能造成影响。
还需注意的是，加热丝60的数量是非限制性的。举例来说，加热丝60可以为一根、也可以为多根。当加热丝60为多根时，多根加热丝60均固定在防火护板80上。通过增加加热丝60的数量，提高了加热丝60给空气传导的热量，使得流经加热丝60的干热空气能够更快的升温。
图9为本申请实施例中防火护板与加热丝连接的立体示意图。图9所示的示例中，防火护板80包括第一围壁81、第三围壁83以及位于第一围壁81和第三围壁83之间的第二围壁82，第二围壁82与第一围壁81以及第三围壁83垂直连接，第一围壁81和第三围壁83均与箱体10的后侧板11连接。当防火护板80安装在箱体10上时，第二围壁82与箱体10的后侧板11平行。
继续参照图9，第一围壁81背离第二围壁82的一端可以凸出设置有朝向第三围壁83的第一连接边810，第三围壁83背离第二围壁82的一端可以凸出设置有朝向第一围壁81的第二连接边830，第一连接边810和第二连接边830均与后侧板11连接。通过形成第一连接边810和第二连接边830，使得防火护板80更容易与后侧板11进行连接，则防火护板80的安装更方便。
其中，第一连接边810以及第二连接边830与箱体10的连接方式是非限制性的。较佳的，第一连接边810以及第二连接边830与箱体10的后侧板11均可拆卸连接，则防火护板80能够从箱体10上拆卸下来，便于对热泵干衣机100进行维护。举例来说，第一连 接边810上设有连接通孔，后侧板11上设有螺孔，螺孔与连接通孔正对，将螺接件穿过连接通孔后与螺孔螺纹连接。
防火护板80和加热丝60可以设置在第二段的任意位置，本实施例对此不做限制。较佳的，防火护板80可以设置在通风罩壳70内并靠近风机出口，也即设置在风机40与通风罩壳70的连通处。这样，加热丝60也靠近风机出口，进而使得由风机出口流出的干热空气均能流经加热丝60，以使尽可能多的干热空气能够被二次加热。
进一步地，第二围壁82的下端朝下凸出设置有下导流板821，下导流板821倾斜延伸，下导流板821由下至上与后侧板11之间的距离逐渐增大。如此设置，当防火护板80靠近风机出口设置时，可以使下导流板821与风机出口相接触，下导流板821能够引导从风机出口流出的干热空气进入通风罩壳70内。
更进一步地，第二围壁82的上端朝上凸出设置有上导流板820，上导流板820倾斜延伸，且上导流板820由下至上与后侧板11之间的距离逐渐增大。通过设置上导流板820，上导流板820能够起到导流作用，以引导流经加热丝60的空气由安装空间流出并往进风口流动。需要指出的是，此时，第二围壁82与通风罩壳70之间存在一定的间隙。
在上述实施例中，防火护板80可以为金属板，例如钢板、镀锌板，防火护板80也可以为涂油防火涂料的护板，本实施例对此不做限制。
