具体地，如图1所示，在第一实施例中，该绝缘板100包括用于与热水器的内壁挂板200相连的底座110、面向热水器壳体内壁的顶壁120，底座110及顶壁120均呈板面状间隔设置，板面状可以是实心的板面或空心的板面，以使底座110及顶壁120之间具有有效的隔热面，此外，底座110及顶壁120间隔设置是指：顶壁120距离底座110之间具有一定的距离，可以使该隔热面在顶壁120与底座110之间形成以隔热面为截面的隔热空间，该隔热空间的厚度为顶壁120到底座110之间的距离。为了对该隔热空间形成围合，绝缘板100还包括连接底座110及顶壁120的侧壁130，此处的侧壁130可以是一个或多个。当侧壁130的数量为一个时，绝缘板100具有开口的腔体140，侧壁130的数量也可以为多个用以连接底座110及顶壁120以围合成一密闭的腔体140，本领域技术人员可以通过本发明实施例及附图，获得相应的解决方案，在此不一一赘述。该腔体140内可以通过设置具有一定厚度的隔热件，该隔热件容置在腔体140内并填满该腔体140，以增大绝缘板100的有效隔热体积；也可以通过向腔体140内注入发泡的隔热料来填满该腔体140，以增大绝缘板100的有效隔热体积，随着隔热体积的增大，绝缘板100的隔热性能越好，并且，隔热件或隔热料为导热系数小于0.12瓦/米•度的保温材料，需要阐明的是，此处所述的隔热件或隔热料的种类可以有多种，如聚氨酯、酚醛、发泡聚丙烯EPP等，以提高绝缘板100的整体隔热性能，阻隔热水器内胆的热量通过内壁挂板200往外散失，使热水器更节能。
参照图1所示，第一实施例中，绝缘板100的侧壁130为多个，多个侧壁130围合形成腔体140，用于容置隔热料。为便于隔热料在腔体140内填充，并达到较好的隔热效果，绝缘板100的腔体140内填充有聚氨酯发泡料。便于使隔热料在腔体140内定型及稳固，在本实施例中，绝缘板100的腔体140内设有筋板150，筋板150可以为一个或多个，该筋板150将腔体140划分为若干个内腔，筋板150的凸起高度低于侧壁130的高度，可以使聚氨酯发泡料顺利地在内腔之间发泡以注满腔体140。此外，该筋板150可以加强绝缘板100的刚性。
参照图2所示，第二实施例中，绝缘板100的侧壁130为一个，该侧壁130位于底座110的一侧与顶壁120相连以形成侧边开口的腔体140，该侧边开口的腔体140便于放入隔热件，或/及内壁挂板200，隔热件的种类可以是前述的保温材料。优选地，出于获得较好的隔热效果，绝缘板100的腔体140内设置有气凝胶毡211，气凝胶毡211是导热系数较低的高保温材料，可以通过设置成薄毡形式插入该开口的腔体140内，当然，该气凝胶毡211可以是通过胶接、捆扎或卡接等多种形式固定在腔体140内，本领域技术人员可以通过本发明实施例及附图获得相应的技术方案，在此不作赘述。出于简化组装的目的，气凝胶毡211与绝缘板100一体复合成型以节省隔热件在腔体140内的安装步骤。
本发明还提出一种壁挂安装结构。
该壁挂安装结构包括内壁挂板200、连接件300及前述的绝缘板100，内壁挂板200固定在热水器的内胆外；绝缘板100与内壁挂板200连接；连接件300穿过绝缘板100固定在内壁挂板200上。
具体地，如图1和图3所示，在第一实施例中，该壁挂安装结构包括内壁挂板200、连接件300及绝缘板100，内壁挂板200固定在热水器的内胆外，固定连接的方式可以有多种，如焊接、铆接或螺接等，出于降低成本的因素考虑，主要采用焊接方式。通过固定连接，使内胆的重量可以通过内壁挂板200实施承重，绝缘板100与内壁挂板200连接，此处所述的连接可以是固定连接及可拆卸连接等，其中，绝缘板100通过连接件300穿过并固定在内壁挂板200上，可以使绝缘板100更为牢固地安装在内壁挂板200上，并且，通过连接件300与内壁挂板200固定连接，通过连接件300承重后挂壁安装，从而使内胆安装在墙上。该绝缘板100具有较高的电阻率，并且，由于该绝缘板100具有上述实施例中的所有效果，绝缘板100具有较好的隔热性能，可以阻隔内胆的热量往外散失，改善了热水器内胆的保温性能，使热水器更节能。
为了使发泡的隔热料更容易进入绝缘板100的腔体140内，便于隔热料填充，使隔热效果较为理想。如图3所示，第一实施例中，绝缘板100的底座110具有与内壁挂板200贴合的安装面111，以对内壁挂板200实施良好的绝缘隔离作用。该安装面111上设有卡扣112，使绝缘板100可以通过卡扣112卡接固定在内壁挂板200上。安装面111上设有开口113，该开口113与所述腔体140连通，内壁挂板200设有第一通孔210，第一通孔210与开口113连通，以令隔热料可以通过该第一通孔210流经绝缘板100及填充腔体140，发泡的隔热料在腔体140内凝固形成隔热层，获得较理想的隔热效果。
为了更为稳固地将绝缘板100安装在内壁挂板200上，本实施例中，绝缘板100设有第一安装孔150，内壁挂板200设有第一镶嵌螺母220，连接件300为螺栓。该螺栓穿过第一安装孔150后，固定在第一镶嵌螺母220上，通过螺接固定使绝缘板100进一步抵靠并固定在内壁挂板200上，使安装方式更为稳固。
考虑到绝缘板100在内壁挂板200上的安装定位，本实施例中，绝缘板100的底座110设有连接柱114，该连接柱114朝内壁挂板200方向凸设，连接柱114穿过第一通孔210。为了使隔热料更为顺利进入到绝缘板100的顶壁120与热水器壳体的内壁之间的间隙，连接柱114设有连通顶壁120的第二通孔115，以使隔热料可以通过第二通孔115注入到该间隙内。
为了更进一步对内壁挂板200进行隔热，参照图2所示，在第二实施例中，内壁挂板200的挂壁安装面320设置在绝缘板100的底座110与顶壁120之间并位于腔体140内，通过绝缘板100的底座110与顶壁120相互包夹住该挂壁安装面320，以使挂壁安装面320的法向形成双面阻隔，使内壁挂板200的热量较难通过挂壁安装面320散失。绝缘板100的顶壁120向腔体140内凸设有凸起部121，该凸起部121的形状可以有多种，如柱状、楔形或其它形状等，内壁挂板200上设有第三通孔230，该凸起部121插入第三通孔230内，以使绝缘板100固定在内壁挂板200上。
为了更稳固地将绝缘板100安装在内壁挂板200上，本实施例中，绝缘板100的顶壁120设有第二安装孔122，内壁挂板200上设有第三安装孔240，底座110设有第二镶嵌螺母116，连接件300为螺栓，该螺栓穿过第二安装孔122及第三安装孔240固定在第二镶嵌螺母116上，将内壁挂板200及绝缘板100螺接在一起，使安装方式更为稳固。为了减薄绝缘板100的厚度，在本实施例中，底座110朝顶壁120方向凸设有凸包117，使第二镶嵌螺母116可以容置在凸包117内，以减薄绝缘板100的整体厚度。
本发明还提出一种热水器，该热水器包括多个前述的壁挂安装结构，该壁挂安装结构的具体结构参照上述实施例，由于本热水器采用了上述所有实施例的全部技术方案，因此同样具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
