具体实施方式
为使本申请的上述目的、特征和优点能够更加明显易懂，下面结合附图对本申请的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本申请。但是本申请能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本申请内涵的情况下做类似改进，因此本申请不受下面公开的具体实施的限制。
需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。
除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请。以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
如图1和图2所示，在一个实施例中提供了一种取暖设备10，包括壳体11以及设置在所述壳体11中的电热膜片12和风机13，所述风机13位于所述电热膜片12的底部，所述风机13的进风口朝上，所述风机13的出风口朝前，所述壳体11上与所述出风口对应的位置设有通风孔1111。
使用时，通过所述电热膜片12和所述风机13的协同作用使得所述取暖设备10前方的人体感温效果较好。具体地，如图2所示，基于所述电热膜片12的高辐射能力，向所述取暖设备10的前方辐射大量热量。而所述风机13位于所述电热膜片12的底部，且风机13的出风口朝前，在实现地毯式供暖的同时，出风口吹出的气流也将取暖设备10前方辐射的大量热量向前引导推进，如图2所示，使得所述取暖设备10前方近地位置的温度 较高，整体上提升所述取暖设备10前方的人体感温效果。
如图3所示，相对于非电热模片式的取暖设备而言，即使在非电热膜片式的取暖设备中设置风机进行地毯式供暖，但是基于没有电热膜片能够向取暖设备前方辐射大量热量，从而没有大量热量向前推进，无法达到上述提升人体感温的效果。如图3所示，在人体高度1m～0.4m范围内，相对于非电热膜片式取暖设备即使设置了风机，在没有大量热量向前推进的情况下，也无法达到本申请中所述取暖设备10所能达到的温度。而单纯的电热模式取暖设备只能够通过辐射和自然对流供暖，但是基于自然对流热量上浮，也无法达到本申请所述取暖设备10能够实现的人体感温效果。
在一实施例，如图1所示，所述壳体11可以是由上板112、底板和两个侧板114围成的框架结构，所述电热膜片12和所述风机13设置在所述壳体11围成的框架结构内；或如图4所示，所述壳体11由上板112、底板、前板111、背板113和两个侧板114围成，所述电热膜片12和所述风机13则被所述壳体11保护在内，避免外界的误触碰。或者所述壳体11可以为其他框架结构形式，只要能够对所述电热膜片12和风机13起到支撑固定的作用即可。
进一步地，在一个实施例中，如图2、图4至图6所示，所述壳体11包括前板111，这里所述的前板111即所述壳体11所包含的位于所述电热膜片12和风机13前方的挡板，所述通风孔1111则设置在所述前板111上与所述风机13对应的位置。当所述壳体11不包括前板111时，所述风机13的出风口则没有物体遮挡，则所述壳体11自然围成了一个敞口，所述通风孔则为所述敞口的一部分。
进一步地，在一个实施例中，当所述壳体11包括前板111时，如图2、图4至图6所示，可以在所述通风孔1111处设置通风格栅。而且进一步地，可以将所述通风格栅的叶片14设置为转动的形式，调整从所述通风格栅吹出的风的走向。具体地，所述通风格栅的叶片14沿所述壳体11的横向设置，所述叶片14的两端与所述壳体11转动连接，从而使得所述叶片14的角度可调节。
可选地，所述通风孔1111也可以由多个条形孔间隔设置而成，多个条形孔在所述壳体11的纵向上间隔设置。
可选地，所述通风格栅中相邻两个叶片14的转轴之间的间距为5mm～10mm。
进一步具体地，所述风机13可以为贯流风机，或者为其他形式的风机13，在这里不做具体限制。
如图1、图2和图4至图6所示，当所述风机13为贯流风机时，所述贯流风机的轴线沿所述壳体11的横向设置，所述贯流风机的出风口朝前。如此，可以较好的将壳体11中 经过换热的空气吹出，形成地毯式供热的效果。
进一步地，当所述风机13为贯流风机时，为提升整体的通风效果，所述通风孔1111在所述壳体11横向上的长度不小于所述贯流风机轴向上的长度。自然，当所述通风孔1111设有通风格栅时，所述通风格栅的叶片14在壳体11横向上的长度不小于所述贯流风机轴向上的长度。
在所述壳体11的纵向上所述通风孔1111的最高点位于所述贯流风机的最高点与所述电热膜片12的最低点之间，所述通风孔1111在所述壳体11的纵向上的高度不小于所述贯流风机的直径，即所述通风孔1111的最低点不高于所述贯流风机的最低点，保障了通风孔1111对贯流风机导风的目的。
进一步地，在一个实施例中，如图1、图5和图6所示，所述电热膜片12为多个，多个电热膜片12在壳体11中依次间隔设置，多个电热膜片12横向分布，辐射的热量直接被人体表面吸收。在所述壳体11中形成换热空间，进入所述壳体11中换热空间的空气与所述电热膜片12之间进行换热，如图2所示，携带热量的空气被风机13吸入，然后从风机13的出风口排出。风机13在将热空气排出实现地毯式供暖的同时，将电热膜片12辐射的大量热量向前推进。
具体地，这里的电热膜片12为高发射率的膜片。在一个实施例中，所述电热膜片12的发射率为0.9。
进一步地，在一个实施例中，如图5和图6所示，所述壳体11包括前板111，所述通风孔1111设置在所述前板111上与所述风机13对应的位置，所述前板111上与所述电热膜片12对应的位置为辐射位，所述辐射位设有多个导热孔1112，电热膜片12产生的热量通过所述导热孔1112向前辐射。
进一步地，在一个实施例中，多个导热孔1112在所述辐射位均匀间隔分布。具体地，如图5和图6所示，所述导热孔1112为菱形孔或圆孔。可选地，所述导热孔1112也可以为其他形状的孔，在这里不做具体限制。
进一步可选的，如图4所示，所述前板111上的辐射位也可以不设置所述导热孔1112，通过将辐射位采用热量易穿透的板材制作，形成热量易穿透板，能够保障电热膜片12产生的热量向前辐射即可。
进一步地，如图7所示，在一个实施例中，所述壳体11包括上板112，所述上板112上设有多个上吸风口1121。在使用的过程中，如图2所示，外界空气从所述上吸风口1121进入所述壳体11中进行换热。进一步地，可以将多个上吸风口1121在上板112上均匀间隔分布。
进一步地，如图8所示，也可以在所述壳体11的所述背板113上设置多个后吸风口1131，以达到外界空气进入壳体11的目的。
具体地，如图8所示，多个后吸风口1131位于所述背板113的上端，如此进入壳体11中的外界空气能够较好的与电热膜片12进行换热后向下流动，被风机13吹出。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
