具体实施方式
以下将结合附图所示的具体实施方式对本发明进行详细描述。但这些实施方式并不限制本发明，本领域的普通技术人员根据这些实施方式所作出的结构、方法、或功能上的变换均包含在本发明的保护范围内。
本发明提供一种制冷电器，制冷电器可以是冰箱1、冷柜、商用展示柜等。下面将以冰箱1为例对该制冷电器进行说明。
参照图1-图4，在本实施方式中，冰箱1，可以包括蒸发器间室2，所述蒸发器间室2可以包括开口3，其中，所述冰箱1还可以包括：第一壁板4，其封闭环绕于所述开口3外侧且内接于所述开口3；第二壁板5，其封闭环绕于所述第一壁板4外侧，且相对于所述第一壁板4朝远离所述蒸发器间室2方向凸出并和所述第一壁板4之间形成台阶；保温盖板6，其封闭所述开口3；所述保温盖板6可以包括外壳7、内壳8、设置于所述内壳8和所述外壳7之间的VIP板9，所述内壳8可以包括覆盖所述第一壁板4的外周部81，覆盖所述第二壁板5和所述开口3的中间部82，所述中间部82相对于所述外周部81向所述蒸发器间室2凸出，所述VIP板9朝向所述内壳8的一侧呈与所述外周部81及所述中间部82配合的阶梯状。
VIP板9是真空隔热板的简称，是真空保温材料中的一种，由填充芯材与真空保护表层复合而成，它有效地避免空气对流引起的热传递，因此导热系数可大幅度降低，具有环保和高效节能的特性。保温盖板6相对于其他保温材料而言，占据的空间体积更小，保温效能更高，因而在保温盖板6中使用VIP板9，能够减少保温盖板6的厚度的同时，提高保温盖板6的保温效果。
在蒸发器间室2开口3处设置形成台阶的第一壁板4和第二壁板5，第二壁板5相对于第一壁板4向外凸出，保温盖板6覆盖开口3的同时，也覆盖在开口3外侧的第一壁板4和第二壁板5上。VIP板9不仅和内壳8的外周部81配合，覆盖在第一壁板4处，而且和内壳8的中间部82配合，朝向蒸发器间室2凸出，覆盖在第二壁板5和开口3处。
如此设置，能够使保温盖板6更好的封闭蒸发器间室2的开口3，隔绝保温盖板6外部空间和蒸发器间室2之间的热量传输，阻挡蒸发器 间室2内的冷气向外扩散，提高蒸发器间室2的保温效果，能够有效提高VIP板9的覆盖范围，增加VIP板9的厚度，提高保温盖板6的保温效果，同时能够减少保温盖板6对蒸发器间室2外部空间的占用。
参照图1-图2，进一步的，在本发明另一实施方式中，所述冰箱1可以包括冷藏间室10，所述蒸发器间室2设置于所述冷藏间室10，所述开口3朝向所述冷藏间室10内，所述保温盖板6设置于所述冷藏间室10内；其中，所述冷藏间室10可以包括用于开闭所述冷藏间室10的冷藏门11，所述冷藏门11设置有制冰间室12，所述制冰间室12设置有进风口13和回风口14，所述进风口13和所述蒸发器间室2之间连接有进风风道，所述回风口14和所述蒸发器间室2之间连接有回风风道。
在本实施方式中，冰箱1可以包括箱体15，箱体15内部可以形成有多个用于存储物品的储物间室，例如冷藏间室10、冷冻间室16等。冷藏间室10可以设置于箱体15的上部，冷冻间室16可以设置于箱体15的下部。
制冰间室12可以设置于冷藏门11上，以便于用户取冰。为了保证向制冰间室12的供冷效果，减少因供冷风道过长等造成的能量损耗，可以将蒸发器间室2设置于冷藏间室10内，通过进风风道和回风风道实现蒸发器间室2和制冰间室12之间的冷气互通。
在本实施方式中，蒸发器间室2、第一壁板4、第二壁板5可以由冷藏间室10的内胆一体形成。也可以单独制造蒸发器间室2，在冷藏间室10内胆上开设用于安装蒸发器间室2的安装口，将蒸发器间室2安装在冷藏间室10的安装口处，然后将蒸发器间室2固定在冷藏间室10内。
如此设置，能够保证门体制冰间室12的供冷效果，减少因供冷风道过长等造成的能量损耗,减少设置于冷藏间室10的蒸发器间室2和冷藏间室10之间的热量传输，阻挡蒸发器间室2内冷气向冷藏间室10内扩散，提高蒸发器间室2的保温效果，同时能够减少保温盖板6对冷藏间室10空间的占用，提高冷藏间室10空间的利用率。
进一步的，在本发明另一实施方式中，所述VIP板9贴设于所述外壳7且与所述内壳8间隔设置形成发泡空间，所述发泡空间内填充有发泡材料。
VIP板9的形状一般呈规则的板型，由于保温盖板6内壳8往往需 要和蒸发器间室2内的蒸发器结构等配合，内壳8往往具有不规则的形状，而保温盖板6的外壳7往往是规则的平板状，因而将VIP板9贴设于外壳7上，能够使VIP板9的结构更加简单，且便于VIP板9的安装。
由于VIP板9很难实现和保温盖板6外壳7和内壳8紧密结合，通过在VIP板9内部填充发泡材料，能够弥合VIP板9和内壳8和外壳7之间的间隙，提高保温盖板6的保温效果，同时，能够将VIP板9稳定的固定在保温盖板6内部。
参照图4，进一步的，在本发明另一实施方式中，所述VIP板9可以包括呈阶梯状连接的第一平板91和第二平板92，所述第一平板91设置于所述外壳7侧，所述第二平板92设置于所述内壳8侧，所述第一平板91的尺寸大于所述第二平板92，所述第一平板91和所述第二平板92一体成型或分体式连接。
在本实施方式中，VIP板9可以由两个平板即第一平板91和第二平板92结合形成。第一平板91可以贴设于外壳7上且和外壳7尺寸相配合。第二平板92可以相对于第一平板91向蒸发器间室2凸出，和保温盖板6的内壳8的尺寸相互配合。第二平板92可以和第一平板91是一体式的制造，也可以是分别制造出，通过胶水等将第二平板92连接在第一平板91上。
如此设置，能够提高保温盖板6中VIP板9占据的空间以及VIP板9的厚度的同时，使VIP板9的结构较为简单，便于VIP板9的加工和制造，降低生产成本。
参照图4-图5，进一步的，在本发明另一实施方式中，所述外壳7可以包括呈平面状的板主体71，所述板主体71周缘朝向所述内壳8延伸形成外周壁72，所述外周壁72内侧平行间隔设置有内周壁73，所述内周壁73设置有若干间隔设置的第一卡接结构76，所述内壳8设置有延伸至所述外周壁72和所述内周壁73之间的中周壁83，所述中周壁83设置有和所述第一卡接结构76配合的第二卡接结构84。
第一卡接结构76可以是形成在内周壁73上的卡接开口3，第二卡接结构84可以是形成在中周壁83上的卡接凸起。内周壁73的上侧、下侧、左侧、右侧均可以形成有若干第一卡接结构76。
如此设置，能够实现外壳7和内壳8之间的紧密连接，能够形成VIP 板9的安装空间以及发泡材料的填充空间，避免填充发泡材料时出现发泡材料泄露等情形，提高保温盖板6的保温效果，结构简单，组装方便，可靠性高。
参照图2、图4、图5，进一步的，在本发明另一实施方式中，所述第一壁板4形成有若干间隔设置的第一孔41，所述外周部81形成有和所述第一孔41配合的第二孔84，所述外壳7形成有和所述第二孔84配合的第三孔74，所述外周壁72、所述内周壁73、所述中周壁83在所述第二孔84、所述第三孔74处相适应的向内凹弯曲形成弯曲部61，所述弯曲部61形成用于装配连接件的让位区，所述连接件用于将所述保温盖板6连接至所述第一孔41。
第一壁板4的左侧、右侧、下侧均可以形成有若干第一孔41。如此设置，能够实现保温盖板6和第一壁板4之间的稳固连接，保证保温盖板6和第一壁板4、第二壁板5的配合，提高保温盖板6对蒸发器开口3的封闭效果，结构简单，拆装方便，可靠性高。
参照图5，进一步的，在本发明另一实施方式中，所述内周壁73的左侧壁、右侧壁、下侧壁均分别间隔形成有若干所述弯曲部61，所述VIP板9的左侧壁或右侧壁、下侧壁分别与所述内周壁73对应的所述弯曲部61相接。
如此设置，能够通过弯曲部61对VIP板9进行限位，便于将VIP板9装配在外壳7内，同时，使VIP板9在保温盖板6中的固定更加稳固、可靠，防止VIP板9产生位移、晃动。
参照图5，进一步的，在本发明另一实施方式中，所述外壳7还设置有和VIP板9左侧壁或右侧壁相接的突起75。
如此设置，能够实现对VIP板9进行限位，便于将VIP板9装配在外壳7内，同时，使VIP板9在保温盖板6中的固定更加稳固、可靠，防止VIP板9产生位移、晃动。
参照图3-图4，进一步的，在本发明另一实施方式中，所述蒸发器间室2内设置有蒸发器21、设置于所述蒸发器21上方的风扇22，所述中间部82对应所述风扇的区域朝向所述风扇22凸出。
如此设置，能够增加保温盖板6的厚度，提高保温盖板6中保温材料的填充量，进而提高保温盖板6对蒸发器间室2的保温效果。
参照图3-图4，进一步的，在本发明另一实施方式中，所述蒸发器间室2内设置有用于所述蒸发器22化霜的加热装置，所述内壳8朝向所述加热装置的表面贴附有散热板24或隔热板24。
在本实施方式中，散热板24或隔热板24可以采用耐高温的散热或隔热材料制成，如铝板等。如此设置，能够避免加热装置产生的热量集中在保温盖板6特定位置，造成保温盖板6融化、保温性能降低等情形。
参照图4，进一步的，在本发明另一实施方式中，所述中间部82和所述第二壁板5之间设置有密封件。所述中间部82朝向所述密封件内缘延伸形成限位壁85。所述限位壁85高度和所述密封件厚度配合。所述密封件粘贴于所述中间部82。所述密封件可以采用EPDM材质。
通过设置限位壁85可以便于密封件的安装和固定，有利于密封件和内壳8之间的连接。密封件采用EPDM塑胶，能够使密封件具有一定的耐氧化、抗侵蚀的能力，提高密封件的使用寿命和可靠性。
如此设置，能够减少保温盖板6和第二壁板5之间的装配间隙，减少设置于冷藏间室10的蒸发器间室2和冷藏间室10之间的热量传输，阻挡蒸发器间室2内冷气向冷藏间室10内扩散，提高蒸发器间室2的保温效果。
参照图4，进一步的，在本发明另一实施方式中，所述限位壁85间隔设置有若干向所述蒸发器间室2延伸的卡扣86，所述蒸发器间室2侧壁设置有和所述卡扣86配合的卡合结构23。
如此设置，能够连接保温盖板6和蒸发器间室2，使保温盖板6和蒸发器间室2之间的连接更加稳固、可靠、紧密，能够减少蒸发器间室2内冷气泄露，提高蒸发器间室2的保温效果，结构简单，组装方便，可靠性高。
综上所述，本发明中的制冷电器，通过在蒸发器间室2开口3周围设置形成台阶的第一壁板4、第二壁板5，在保温盖板6内设置呈阶梯状的VIP板9，能够解决现有技术中蒸发器间室2和冷藏间室10的温差比较大，若闭合蒸发器间室2开口3的盖板保温效果不好，会使蒸发器间室2内的冷气泄露到冷藏间室10内，造成冷藏间室10内的温度过低的问题。
采用本申请中的技术方案能够使保温盖板6更好的封闭蒸发器间室 2的开口3，隔绝保温盖板6外部空间和蒸发器间室2之间的热量传输，阻挡蒸发器间室2内的冷气向外扩散，提高蒸发器间室2的保温效果，能够有效提高VIP板9的覆盖范围，增加VIP板9的厚度，提高保温盖板6的保温效果，同时能够减少保温盖板6对蒸发器间室2外部空间的占用。
另外，能够保证门体制冰间室12的供冷效果，减少因供冷风道过长等造成的能量损耗,减少设置于冷藏间室10的蒸发器间室2和冷藏间室10之间的热量传输，阻挡蒸发器间室2内冷气向冷藏间室10内扩散，提高蒸发器间室2的保温效果，同时能够减少保温盖板6对冷藏间室10空间的占用，提高冷藏间室10空间的利用率。
