具体实施方式
本公开提出了一种空调，包括壳体100、换热器200、电加热器300、风机400和驱动部500。该空调可有效改善空调内部电加热器300的凝露情况。
其中，壳体100为本公开内容的空调的基础构件，壳体100可以为本公开内容的空调的其它至少部分部件提供安装基础，并起到保护空调的其它至少部分部件的目的。为了使空调的自重相对较轻，且具有较佳的结构强度，壳体100可采用工程塑料与金属材料组合拼接形成。对于壳体100的具体材质，本公开内容不作限制。
壳体100内具有风道110，壳体100开设有进风口120和出风口130，进风口120和出风口130设置于风道110的两端，环境中的空气可通过壳体100的进风口120进入至壳体100的进风通道内，并在空调内换热降温或升温后，通过壳体100的出风口130排出。
风机400设置于壳体100，风机400启动后可在壳体100的风道110内形成风压，使得环境中的空气可通过壳体100的进风口120进入至风道110内，并通过出风口130排出。
换热器200设置于壳体100的风道110内，应理解的是，换热器200为空调的制冷制热的基础构件，环境中的空气进入至壳体100的风道110内后，可通过换热器200与换热器200接触换热，换热器200为内部具有供冷却剂流通的管路，且表面开设有供气流通过的间隙的结构件。在空调的制冷模式下，低温液态冷却剂通过换热器200的管路，空气在通过换热器200表面的间隙的过程中可与换热器200管路内的冷却剂换热，从而使得空气温度降低，进而使得通过壳体100的出风口130排出冷风；在空调的制热模式下，高温气态的冷却剂通过换热器200的管路，空气在通过换热器200表面的间隙的过程中可与换热器200管路内的冷却剂换热，从而使得空调的温度升高，进而使得通过壳体100的出风口130排出热风。
在一些实施方式中，换热器200具有进风面和出风面230，进风面和出风面230位于换热器200相背的两侧，壳体100的风道110内的气流由换热 器200的进风面穿过换热器200，并由换热器200的出风面230排出。
电加热器300设置于壳体100的风道110内，因此流经壳体100的风道110内的气流可与电加热器300接触，电加热器300可采用热敏电阻，当电加热器300通电后可产生大量的热，这样在空调处于制热模式的情况下，电加热器300可对壳体100的风道110内的空气进一步加热，从而使得空调在制热模式下具有更好的制热效果。电加热器300具有加热面310，电加热器300所产生的热量主要分布于电加热器300的加热面310上。
加热面310为电加热器300表面面积相对最大的部分，当电加热器300为矩形体结构时，电加热器300在其长度方向上的横截面为矩形，加热面310即为矩形横截面长边所在的面，以使电加热器300的加热面310的面积相对最大，在空调处于制热模式时，电加热器300的加热面310可设置为与壳体100的风道110内的气流的流向相对，这样壳体100的风道110内通过的气流可与电加热器300的加热面310充分接触，以使电加热器300可充分加热壳体100的风道110内的气流，最终可使得空调处于制热模式下具有更好的制热效果。
当本公开内容的空调处于制冷模式下，电加热器300关闭，电加热器300不再发热，换热器200内的管路内流经低温的冷却剂，因此电加热器300表面的温度相对较低，为了防止电加热器300的表面出现凝露，可使得电加热器300的加热面310与换热器200的出风面230相对，这样低温的换热器200可对电加热器300的加热面310的各部分充分降温，从而可使得电加热器300的加热面310的各部分的温差相对较小，以达到改善电加热器300出现凝露的状况。此外，由换热器200的出风面230排出的气流可直接作用于电加热器300的加热面310上，并使得换热器200的出风面230排出的气流可充分作用于电加热器300的加热面310的各个部分，从而使得电加热器300的加热面310的各部分的温差相对较小，从而可避免电加热器300的加热面310的部分因温度相对较低而出现凝露的状况。
本公开内容中的驱动部500设置于壳体100，驱动部500与电加热器300连接，驱动部500可驱动电加热器300活动，驱动部500可驱动电加热器300在第一位置和第二位置之间切换。在本公开内容的空调处于制热模式下时，驱动部500可驱动电加热器300处于第一位置，在第一位置下，电加热器300的加热面310与壳体100的风道110内的气流流向相对，即电加热器300的加热面310与壳体100的进风口120相对，以使得壳体100的风道110内的气流可充分地与电加热器300的加热面310接触，进而使得壳体100的风道110内的气流可被充分地加热。
在本公开内容的空调处于制冷模式下时，驱动部500可驱动电加热器300处于第二位置，在第二位置下，电加热器300的加热面310与换热器200的出风面230相对，这样可使得通过换热器200的出风面230排出的冷气流可 充分地作用于电加热器300的加热面310，进而使得电加热器300的加热面310的各部分温差相对较小，从而可有效地改善电加热器300因其局部温度过低而产生凝露的状况。
本公开内容提出的空调中，驱动部500设置为与电加热器300连接，使得驱动部500可驱动电加热器300活动，从而使得电加热器300可在第一位置和第二位置之间切换，在空调处于制热模式下，电加热器300通电产生热量，驱动部500驱动电加热器300处于第一位置，即电加热器300的加热面310与壳体100的风道110内的气流的流向相对，以使得壳体100的风道110内的气流可充分地与电加热器300的加热面310接触，进而使得壳体100的风道110内的气流可被充分地加热。在空调处于制冷模式下，电加热器300关闭，驱动部500驱动电加热器300处于第二位置，即电加热器300的加热面310与换热器200的出风面230相对，这样可使得通过换热器200内的低温冷却剂以及由出风面230排出的冷气流可充分地作用于电加热器300的加热面310，进而使得电加热器300的加热面310的各部分温差相对较小，从而可有效地改善电加热器300因其部分温度过低而产生凝露的状况。
因此，通过设置驱动部500，使得本公开内容的空调在制热模式下具有良好的制热效果，在制冷模式下可有效地改善电加热器300上产生凝露的状况。
在一些实施方式中，为了便于将驱动部500设置为与电加热器300连接，本公开内容的空调还可设置有安装部600，安装部600可设置于换热器200的侧部，电加热器300的至少一端可与安装部600可转动连接，以使电加热器300可固定于空调的壳体100内，驱动部500可设置于安装部600并与电加热器300的端部连接。
在一些实施方式中，为了使本公开内容的驱动部500驱动电加热器300在第一位置和第二位置之间切换更加效率，可设置驱动部500驱动电加热器300转动，电加热器300在转动过程中实现在第一位置和第二位置之间的相互切换，可使得电加热器300在第一位置和第二位置之间切换的过程中切换效率更高，且使得电加热器300的活动幅度相对更小，从而可达到节省壳体100内空间的目的。
本公开内容的换热器200的出风面230可设置为与壳体100的风道110内的气流方向具有一定的夹角，换热器200的出风面230与壳体100的风道110内的气流方向的夹角具体为锐角，这样使得壳体100的风道110内的气流方向与换热器200的出风面230的朝向不同。当壳体100的风道110内的气流的流向为竖直向下流动时，换热器200相对壳体100的风道110内的气流流向倾斜设置于风道110内，这样在换热器200表面积一定的情况下，可使得换热器200占用的壳体100内的风道110的宽度空间相对更小。
当换热器200的出风面230设置为与壳体100的风道110内的气流流向 相垂直时，即为换热器200水平设置于壳体100的风道110内，这样若需要使换热器200具有更大的表面积以使空气与换热器200充分换热，换热器200在壳体100的风道110的水平方向上所占用的空间更大，进而使得壳体100的整体宽度尺寸更大，而当换热器200的出风面230相对壳体100的风道110内的气流方向倾斜设置后，可使得换热器200倾斜设置于壳体100的风道110内，这样在换热器200的表面积一定的情况下，可使得换热器200占用的风道110的宽度尺寸更小，进而使得壳体100的宽度尺寸可设置更小，达到使得本公开内容的空调的结构更加紧凑的目的。
在换热器200的出风面230的朝向与壳体100的风道110内的气流流量不一致的情况下，通过驱动部500转动电加热器300，可在电加热器300的位移幅度相对较小的情况下使得电加热器300的加热面310分别与换热器200的出风面230和壳体100的风道110内的气流流向相对，从而达到使得驱动部500更高效地驱动电加热器300在第一位置和第二位置之间切换的目的。
当然，在其它实施方式中，本公开内容的驱动部500还可设置为可驱动电加热器300移动，以使电加热器300的加热面310与换热器200的出风面230相对，或使电加热器300的加热面310与壳体100的风道110内的气流流向相对，当本公开内容的换热器200为异形结构的情况下，可使得壳体100的风道110内的气流与换热器200的部分表面区域直接接触。当本公开内容的空调处于加热模式下时，驱动部500可驱动电加热器300移动至与壳体100的风道110内的气流的流向相对，而当本公开内容的空调处于制冷模式下时，驱动部500可驱动电加热器300移动至与换热器200上气流流经的部分相错开，这样可使得电加热器300的加热面310与换热器200充分接触，以改善电加热器300产生凝露的问题。
在一些实施方式中，为了使驱动部500可驱动部电加热器300转动，驱动部500可采用电机，电加热器300可架设于壳体100的风道100内，电机的输出端可与电加热器300的一端连接，从而驱动电加热器300转动。驱动部500可设置于壳体100的侧壁上，电加热器300的两端可转动的与壳体100的两侧侧壁连接。
在一些实施方式中，为了使本公开内容的壳体100的风道110内气流可经过换热器200和电加热器300，换热器200和电加热器300可沿壳体100的风道110内的气流流向依次分布于壳体100的风道110内。这样壳体100的风道110内的气流可先经过换热器200后再与电加热器300接触，本公开内容的空调处于制热状态时，换热器200的管道内流经高温的冷却剂，风道110内的气流可先与换热器200接触换热，使得风道110内的气流可形成高温气流，高温气流随后再与电加热器300接触，以使电加热器300可更进一步加热壳体100的风道110内的气流，进而使得壳体100的风道110内的气流的温度更高，最终可使得本公开内容的空调在制热模式下具有更好的制热效果。
在一些实施方式中，当本公开内容的空调处于制冷模式时，电加热器300处于第二位置，电加热器300的加热面310与换热器200的出风面230相对，为了使换热器200作用于电加热器300的加热面310的效果更佳，进而使得电加热器300的加热面310的各部分温差更小，可设置电加热器300的加热面310与换热器200的出风面230的夹角为0度-10度，在这一角度范围内，可使得电加热器300的加热面310的各部分与换热器200的出风面230的间距较为一致，从而可使得换热器200对电加热器300的加热面310的各个部分的作用效果较为一致，进而使得本公开内容的空调具有更好的改善电加热器300凝露的效果。
当电加热器300的加热面310与换热器200的出风面230的夹角设置为0度时，可使得电加热器300的加热面310与换热器200的出风面230相互平行，这样可使得加热面310与换热器200的出风面230之间的各部分的间距一致，这样在本公开内容的额空调处于制冷模式下，换热器200对电加热器300的加热面310的各部分的降温效果一致，可使得电加热器300的加热面310的各部分的温差更小，从而可有效地改善电加热器300的凝露问题。
当然，应理解的是，在电加热器300的加热面310与换热器200的出风面230的夹角为0度-10度这一范围内，均可使得电加热器300的加热面310的各部分与换热器200的出风面230的间距较为一致，从而均可达到改善电加热器300的凝露的效果。
在一些实施方式中，为了使本公开内容的换热器200具有更大的表面积，进而具有更好的换热效果，本公开内容的换热器200可设置为包括中蒸部210和后蒸部220，中蒸部210和后蒸部220连接为一体结构，且中蒸部210和后蒸部220可分布设置于壳体100的风道110的两侧，壳体100的风道110内的气流可穿过中蒸部210和后蒸部220，这样中蒸部210和后蒸部220均可加热或冷却气流，从而使得本公开内容的空调的制热和制冷效果更佳。电加热器300可设置于中蒸部210和后蒸部220之间，驱动部500可驱动电加热器300转动，使得电加热器300的加热面310可与中蒸部210的出风面230或后蒸部220的出风面230相对。
应理解的是，中蒸部210和后蒸部220为换热器200处于壳体100的风道110内不同位置的部分，因此冷却剂在中蒸部210和后蒸部220内的管路流动时，因中蒸部210后蒸部220的安装位置以及具体结构差异的影响，会使得中蒸部210和后蒸部220无法保持完全一致的温度，因此中蒸部210和后蒸部220之间会具有一定的温差。还应理解的是，在空调制冷模式下，电加热器300产生凝露的主要原因为换热器200内的低温冷却剂作用于壳体100的风道110内的气流，使得气流温度降低而产生附着于电加热器300上的凝露，因此若电加热器300的温度可提高，那么可有效地解决电加热部凝露的问题。
当空调处于制冷模式下，可通过驱动部500驱动电加热器300的加热面310与中蒸部210和后蒸部220中温度相对更高的一个的出风面230相对，这样可使得电加热部受到换热器200内的低温冷却剂的影响相对更小，从而可使得电加热器300的加热面310的温度相对更高，从而可更进一步地改善电加热器300的凝露问题。
在一些实施方式中，为了使本公开内容中的驱动部500可驱动电加热器300的加热面310更快地转动至与中蒸部210的出风面230相对，或是与后蒸部220的出风面230相对，电加热器300的加热面310可设置为两个，两个加热面310可设置于电加热器300相背的两侧。当驱动部500驱动电加热器300处于第一位置时，电加热器300的两个加热面310中的任意一个加热面310可与壳体100的风道110内的气流的流向相对，以加热壳体100的风道110内的气流；当驱动部500驱动电加热器300处于第二位置时，电加热器300的两个加热面310中的任意一个加热面310可与中蒸部210的出风面230或后蒸部220的出风面230相对。
应理解的是，在中蒸部210和后蒸部220非对称地设置于壳体100的风道110内的情况下，电加热器300的两个相背的加热面310转动至与中蒸部210的出风面230相对或转动至与后蒸部220的出风面230相对时所需转动的角度不同，因此，在电加热器300上设置两个加热面310后，当中蒸部210的温度相对更高后，可通过驱动部500驱动两个加热面310中转动至与中蒸部210的出风面230相对所需转动角度更小的加热面310转动至与中蒸部210的出风面230相对，当后蒸部220的温度相对更高后，可通过驱动部500驱动两个加热面310中转动至与后蒸部220的出风面230相对所需转动角度更小的加热面310转动至与后蒸部220的出风面230相对，这样可减小驱动部500驱动电加热器300转动的角度，可使得电加热器300的加热面310可更快地与中蒸部210的出风面230或后蒸部220的出风面230相对。
在一些实施方式中，本公开内容的电加热器300设置有旋转中心，驱动部500可驱动电加热器300绕旋转中心转动，电加热器300还具有穿过旋转中心并且与中蒸部210和后蒸部220的连接处连接的预设连线330，中蒸部210的出风面230与预设连线330之间可形成第一夹角，后蒸部220的出风面230与预设连线330之间可形成第二夹角，第一夹角和第二夹角之间的差值不超过15度，这样可使得中蒸部210的出风面230和后蒸部220的出风面230可相对平衡地设置于电加热器300的相对两侧，从而可使得中蒸部210的出风面230和后蒸部220的出风面230与电加热器300的间距较为接近，从而可在一定程度上使得中蒸部210和后蒸部220对电加热器300的作用效果较为一直，以更进一步地改善电加热器300的凝露问题。
在一些实施方式中，由于壳体100的风道110内设置有风机400和换热器200，为了防止驱动部500驱动电加热器300移动或转动过程中电加热器 300与换热器200和风机400碰撞，可将电加热器300与风机400的间距设置为大于等于15mm，在这一间距范围内使得风机400与电加热器300不会相互干涉，且风机400可将经过电加热器300加热的空气充分地由壳体100的出风口130排出。
本公开内容中可将电加热器300与中蒸部210的间距以及电加热器300与后蒸部220的间距均设置为至少20mm，在这一间距范围可可使得电加热器300与中蒸部210和后蒸部220不会相互干涉，且在空调处于制热模式下时，可使得穿过中蒸部210和后蒸部220的气流可更快的与电加热器300接触，在空调处于制冷模式下，可使得中蒸部210和后蒸部220可充分作用于电加热器300，以达到改善电加热器300凝露问题的效果。
实施例二
基于本公开内容的空调，本公开内容还提出了一种空调控制方法，该方法可应用于本公开内容的空调中。本公开内容的空调控制方法可设置为包括以下步骤。
首先，可通过设置于换热器200的温度传感器检测换热器200的温度，并通过设置于环境中的温度传感器检测环境内的温度，这样可获取换热器200的温度数值和环境中的温度数值。
随后，可将环境中的温度数值与换热器200的温度数值比较，当环境温度低于换热器200的温度时，表明环境温度相对较低，此时换热器200内流动的冷却剂为高温气态冷却剂，换热器200可将穿过换热器200的气流加热，从而使得空调的出风口130排出的气流为热气流，热气流可提升环境中的温度，因此此时空调处于制热模式。
在制热模式下，驱动部500可驱动电加热器300处于第一位置，即电加热器300的加热面310与壳体100的风道110内气流的流向相对，以使壳体100的风道110内的气流可被电加热器300的加热面310充分加热，进而使得本公开内容的空调具有更好的制热效果。
当环境温度大于换热器200的温度时，表明环境温度相对较高，此时换热器200内流动的冷却剂为低温液态冷却剂，换热器200可将穿过换热器200的气流冷却，从而使得空调的出风口130排出的气流为冷气流，冷气流可提升环境中的温度，因此此时空调处于制冷模式。
在制冷模式下，驱动部500可驱动电加热器300处于第二位置，即电加热器300的加热面310与换热器200的出风面230相对设置，这样可使得换热器200内的低温冷却剂以及通过换热器200的冷气体可较为均匀地作用于电加热器300的加热面310，以使电加热器300的加热面310各部分的温度较为一致，从而可有效地改善空调制冷模式下电加热器300的凝露问题。
在一些实施方式中，为了更进一步地精确控制电加热器300，使得在空调制冷模式下电加热器300的凝露问题进一步改善，本公开内容可设置第一 温度传感器、第二温度传感器和第三温度传感器，第二温度传感器和第三温度传感器分别设置于中蒸部210和后蒸部220，第二温度传感器可检测中蒸部210的温度，第三温度传感器可检测后蒸部220的温度，第一温度传感器可检测环境中的温度。
通过比较环境温度、中蒸部210的温度和后蒸部220的温度，可获取空调的具体的模式，当环境温度同时高于中蒸部210的温度和后蒸部220的温度时，空调处于制冷模式，当环境温度同时低于中蒸部210的温度和后蒸部220的温度时，空调处于制热模式。
随后可比较中蒸部210的温度和后蒸部220的温度，当中蒸部210的温度相比于后蒸部220的温度更高后，可通过驱动部500驱动电加热器300的加热面310与中蒸部210的出风面230相对，进而使得中蒸部210和通过中蒸部210的气流作用于电加热器300的加热面310，可使得电加热器300的加热面310的温度相对更高，从而可更进一步地改善电加热器300的凝露问题。
当后蒸部220的温度相对于中蒸部210的温度更高后，可通过驱动部500驱动电加热器300的加热面310与后蒸部220的出风面230相对，进而使得后蒸部220和通过后蒸部220的气流作用于电加热器300的加热面310，可使得电加热器300的加热面310的温度相对更高，从而可更进一步地改善电加热器300的凝露问题。
通过检测中蒸部210和后蒸部220的温度并比较两者的温度高低，可更为精确地控制电加热器300的加热面310，使得电加热器300的加热面310可与中蒸部210和后蒸部220中温度相对更高的一个的出风面230相对，从而可使得电加热器300的温度相对更高，进而更进一步地改善电加热器300的凝露问题。
在一些实施方式中，为了更精细化地控制本公开内容的空调，本公开内容的空调控制方法中，在比较中蒸部210和后蒸部220之前，可先获取中蒸部210和后蒸部220之间的温差，并且将中蒸部210和后蒸部220之间的温差与预设温差比较，当中蒸部210和后蒸部220的温差大于预设温差，说明中蒸部210和后蒸部220的温差过大，进而表明空调的内部结构件出现了问题，如中蒸部210和后蒸部220中管路堵塞导致冷却剂无法顺畅通过。中蒸部210和后蒸部220的温度差值过大会导致设置于中蒸部210和后蒸部220之间的电加热器300更进一步地受中蒸部210和后蒸部220的作用不均匀，从而加重电加热器300的凝露问题。
因此，在中蒸部210和后蒸部220的温度大于预设温差的情况下，可控制空调，以使空调的压缩机的频率降低，这样可在一定程度上提升换热器200的温度，从而在一定程度上改善电加热器300的凝露问题。此外，在中蒸部210和后蒸部220的温度大于预设温差的情况下，还可设置空调可提醒用户对空调进行检修。本公开内容实施例中，预设温差可设置为不大于5摄氏度。
在一些实施方式中，为了使得本公开内容的空调在高温高湿的环境下，仍可改善电加热器300的凝露问题，本公开内容的空调还可设置湿度传感器，可通过第一温度传感器检测环境温度后，将获取的环境温度与预设温度对比，通过湿度传感器检测环境湿度后，将获取的环境湿度与预设湿度对比，在环境温度大于预设温度，且环境湿度大于预设湿度的情况下，可判定环境为高温高湿环境，因此可通过调节空调的导风板，使得空调的出风口130扩大，这样可扩大空调的出风量，进而使得壳体100的风道110内的气流的流量增大，进而使得壳体100内的气流温度提高，从而可有效地改善电加热器300的凝露问题。本公开内容中，预设温度为28摄氏度，预设湿度为85％。
