Description

[根据细则37.2由ISA制定的发明名称]  密封箱 技术领域
本发明所涉及的是中央空调设备的密封箱体,特别是涉及一种由密封板、金属型材构成的接合部件、以及高分子复合材料构成的密封条组合拼装而成的密封箱体。
背景技术
空调系统依照用途不同可分为家用空调、中央空调、冷冻冷藏设备、车用空调等。其中,中央空调又称集中式空调和半集中式空调,是一种通过主机集中提供热源或冷源,并根据设计要求向不同房间输送冷量或热量的复杂控制系统。中央空调系统主要包括中央空调主机、末端设备以及相关的配套设备。中央空调主机为产生冷热源的设备,主要包括活塞式冷水机组、螺杆式冷水机组、离心式冷水机组、溴化锂吸收式冷热水机组,风冷式冷热水机组、水源热泵机组和工商用单元式空调机组等。中央空调末端设备为将冷热源转化为冷热风并进行相关空气处理的设备,主要包括组合式空调机组、风机盘管等。组合式空调机组则是由各种空气处理功能段组装而成的不带冷、热源,冷媒为水,热源为水或蒸汽的一种空气处理设备。具有对空气进行一种或几种处理功能的单元体。这些机组功能段包括:空气混合、均流、粗效过滤、中效过滤、高中效或亚高效过滤、冷却、一次和二次加热、去湿、加湿、送风机、中间、喷水、消声等。中央空调主机、空气处理机组(AHU)或风机盘管等、水管、风管、冷却塔、阀门等共同组成了中央空调系统。
通常空气处理机组是将冷热盘管安装于密封的保温板组成的箱体内, 以保证整个机组设备的制冷或制热功效,而一般冷桥结构的存在将直接影响到密封箱体的隔热效果。为了提高密封箱体的隔热效果,各种形式的无冷桥设计已经为业内所知,例如中国发明专利 ZL01278833.3 公开了一种内框式无冷桥净化空调箱体,包括内框架、以及通过螺钉固定于内框架上的外层保温板。但这种结构相对比较复杂,需要内框架和外保温层结合,使材料的成本上升,且安装费时。
中国实用新型专利 ZL 200420081591.1 公开了另一种无冷桥组合式密封板。这种设计的组合式密封箱体,采用了无框架的结构设计,通过由铝合金型材和密封板构成的盖板、底板及侧板,辅以塑料构件、自攻螺钉、加强筋等构件组合拼装而成。但其缺陷在于安装时的工艺要求高,步骤多,拼接板之间的水平及垂直对准精度难以控制,密封效果较差。
因此,确实需要一种新的结构简单的组合式无冷桥密封箱结构,能够克服上述现有技术的不足,提高安装效率,保证密封效果。
发明内容
本发明的主要目的是提供一种新的中央空调设备的组合式无冷桥密封箱,由可快速组装的密封保温板及其铝合金接合构件,密封保温门板及其门框构件,以及密封条和紧固件组合而成,结构简单,容易拆装,具有优化的无冷桥设计,密封效果好。
根据本发明上述目的所提供的组合式无冷桥密封箱主要由密封保温板、密封板接合构件、接合构件密封条、密封门、门框构件、门框构件密封条,以及紧固件组合而成。其中,所述密封保温板包括内侧面板、外侧面板、和介于内外侧面板之间的隔热层;所述密封门包括内侧面板、外侧面板、介于内外侧面板之间的隔热层,以及套在密封门板周边的包边套;所述密封板接合构件为一体成型的金属构件,包括一种用于使两块成一直线对接的密封板相连接的类型,以及一种用于使两块成直角对接的密封板相连接的类型;所述门框构件为一体成型的金属构件,包括一种用于与成一直线对接的密封板相连接的类型,以及一种用于与成直角对接的密封板相连接的类型。
有利的是,所述接合构件的一部分形成设有母接合部或公接合部的接合端,其另一部分包括外侧壁和内侧壁,形成用于连接密封板的连接端;所述门框构件的一部分形成有母接合部或公接合部的接合端,其另一部分包括由内外侧壁和左右端壁形成的中空柱体以及水平延伸的门框边;因此,接合构件通过其连接端与密封板相连接,密封板与密封板之间成一直线或成直角关系的对接可以通过接合构件之间的接合端的对应母接合部或公接合部相结合,密封门的门框构件与密封板之间成一直线或成直角关系的对接可以通过门框构件的接合端与密封板接合构件的接合端之间的对应母接合部或公接合部相结合,从而实现密封板之间的快速组装。
进一步地,所述接合构件密封条为一体成型的高分子复合材料构件,例如 PVC 塑料,其基本上呈 L 形截面,包括较长的一段和较短的一段,该较短一段内侧定义了扣合结构,例如凸榫槽或钩扣槽,其形状对应于在所述接合构件的端面靠近内侧壁的部分形成的扣合结构,例如凸榫或钩扣,该较长一段内侧所定义的形状与所述接合构件的内侧壁的形状相一致,特别地,所述接合构件的 II 型密封条较短一段的外侧表面还设有至少两个相间隔的软质凸起,因此所述接合构件密封条基本上平行地夹设于所述接合构件的内侧壁与密封板的内侧面板之间。
其有利之处在于,当上述结构的密封板及密封板组合之后,所述接合构件之间通过对应的母接合部或公接合部相互咬合结合,而接合构件密封条则将接合部位的内侧全面封闭,特别是通过 II 型密封条上的软质凸起,将 II 型接合构件内侧与成直角对接的密封板内侧面板之间的缝隙全面封闭,实现了这两种接合部位的无冷桥结构设计,获得良好的密封效果。
另外,所述门框构件密封条为一体成型的高分子复合材料构件,其基本上呈 L 形截面,包括较长的一段和较短的一段,该较短一段内侧定义了扣合结构,例如凸榫槽或钩扣槽,其形状对应于在所述接合构件的端面靠近内侧壁的部分形成的扣合结构,例如凸榫或钩扣,该较长一段内侧所定义的形状与所述门框构件的内侧壁及门框边的形状相一致,特别地,所述门框构件密封条朝向密封门的外表面上也设有多个软质的凸起,对应于密封门边套内侧表面上所设的软质凸起,而且所述门框构件的 II 型密封条较短一段的外侧表面还设有至少两个相间隔的软质凸起,因此所述门框构件密封条基本上平行地紧贴于所述门框构件的内侧表面并基本上包覆所述门框边的周边。
有利的是,当上述结构的密封门、门框构件与密封板组装后,所述门框构件通过对应的母接合部或公接合部相互咬合结合,而门框构件密封条则将其接合部位的内侧全面封闭,特别是,通过 II 型密封条上的软质凸起,将 II 型门框构件内侧与成直角相对接的密封板内侧面板之间的缝隙全面封闭,更特别的是,门框密封条门框边上的软质凸起与密封门包边套上的软质凸起之间相互交错间隔配合,令密封门与门框的接合部位实现无冷桥密封良好的结构设计。
本发明的其它方面和特征及其优点,将在下面结合附图中的具体实施例通过举例的方式在说明书中进行更为详细的介绍。

具体实施方式
以下结合附图详细描述本发明的具体实施方式。
如图 1 所示,根据本发明的组合式无冷桥密封箱 10 主要由密封板 110 、密封板 110 之间的接合构件 120 、密封门 130 、门框构件 140 、直角连接件 150 (见图 5 、 6 、 18 )、接合构件密封条 160 (见图 5 、 14 、 15 )、门框构件密封条 170 (见图 16-17 、图 21-23 )以及紧固件 180 (见图 9 、 10 )组合而成,其详细结构描述如下:
密封箱 10 底部通过紧固螺栓固定于由 C 形钢构成 的 矩形底座 20 上,底座 20 可以通过焊接或者其它任何适当的方式固定于地基上。
作为举例而不是对本发明的限制,图 1 中所示的密封箱 10 为长方体,包括左右两块侧板、一块密封门板、两块前侧板、三块后侧板、三块顶侧板、和三块底侧板。图 2 为图 1 所示的密封箱 10 的主视图,图 3 为沿图 2 中的 A-A 线的剖视图,图 4 为沿图 2 中的 B-B 线的剖视图。其中,成一直线对接的密封板与密封板之间的接合形式应用于,举例来说,如图 3 中所示出的结构部位 I ,其放大的示意图参见图 5A-5B 和图 6A-6B 所示。 左右侧板与前后侧板之间 , 顶板与侧板之间以及底板与侧板之间为成直角连接 ,具体应用于,举例来说,如图 4 中所示出的结构部位 II 与结构部位 III ,其放大的示意图参见后面的图 9A-9B 以及图 10 所示。另外,密封门板与侧密封板成一直线对接的形式应用于图 3 中所示出的结构部位 IV ,而密封门板与侧密封板成直角连接的形式则应用于图 3 中所示出的结构部位 V ,分别如后面的图 21-23 所示。
现参考图 5A -5B ,两块成一直线对接的密封板 110 的端缘分别套有两种对应的 I 型接合构件 120 ,在密封板 110 与接合构件 130 之间采用了一种 I 型密封条 160 。如图所示,密封板 110 的结构主要包括内侧面板 111 、外侧面板 112 、以及内外侧面板之间的隔热层 113 ,举例来说,可以采用 PVC 聚氨酯发泡层。其中,内外侧面板 111 、 112 可以采用金属面板,或任何适当材料的面板。
参考图 6A-6B ,立体示意显示了两块成一直线对接的密封板 110 组合前与组合后的对照,对于密封板直角两边的接合构件 120 ,其水平方向和垂直方向的接合构件 120 和密封条 160 均被切成 45 度斜角,使直角两边的接合构件 120 和密封条 160 的端部可以拼接成直角,于相邻两个接合构件 120 的内部还设有直角连接件 150 ,用于固定连接该密封板 110 直角两边相邻的水平及垂直接合构件 120 ,参考后面的附图 20A-20B 可以更为直观地理解该直角连接件 150 与接合构件 120 之间的连接方式。
第一种 I 型接合构件 120 的结构具有如图 7A -7D 中所示的公接合部 121a ;相对应的,第二种 I 型接合构件 120 的结构具有如图 8A -8D 所示的母接合部 121b 。公接合部 121a 被设计成可咬合于对应的母接合部 121b 之中。这两种 I 型接合构件 120 均为一体成型的铝合金构件,基本上呈 C 形截面,包括形成于接合端上的接合部 121a 、 121b ,还包括面向箱体外部的外侧壁 122 和面向箱体内部的内侧壁 123 形成用于连接密封板 110 的连接端。从这些图中可以看出,沿这些接合构件 120 的长度方向延伸的结构还有:于外侧壁 122 内表面形成有楔形卡槽 124 ;于内侧壁 123 内表面形成有向外凸起的定位条 125 ;内侧壁 123 的自由端还形成大约 45 度向内的斜缘;另外,分别于端面上靠近内侧壁 123 的部位形成有梯形凸榫 126 。该 I 型接合构件 120 的梯形凸榫 126 以及内侧壁 123 的形状和大小对应于 I 型接合构件密封条 160 的内侧形状大小设计,使 I 型接合构件 120 的梯形凸榫 126 以及整个内侧壁 123 外侧被包覆在 I 型接合构件密封条 160 之内。
I 型接合构件密封条 160 由高分子复合材料一体成型,例如 PVC 硬质材料,其结构参考图 14A 和 14B 所示,其基本上呈 L 形截面,包括较长的一段和较短的一段。较长的一段与 I 型接合构件 120 的内侧壁 123 形状大小相配合的,且于该较长一段自由端的内侧形成有斜槽 161 对应于内侧壁 123 的斜缘。较短的一段与 I 型接合构件 120 的端面一部分形状大小相配合,且于该较短一段内侧形成对应于凸榫 126 的榫槽 162 。从图中可以看到,该 I 型密封条 160 较长一段的外侧面,还设有略微向上隆起的挡缘 163 ,可以形成对密封板 110 内侧面板 111 边缘的止挡。
安装时,首先将 I 型铝合金接合构件 120 的内侧壁 123 沿着 I 型密封条 160 内侧的斜槽 161 和榫槽 162 沿长度延伸方向插入,令密封条 160 整个包覆在接合构件 120 的内侧壁 123 和凸榫 126 的外部,然后再将密封板 110 的外侧面板 112 插入 I 型铝合金接合构件 120 的楔形卡槽 124 中时,同时令密封板 110 内侧面板 111 紧贴于 I 型密封条 160 较长一段外侧并止靠于挡缘 163 。如图 5A 所示,可以看出,密封板 110 的内侧面板 111 的预留长度比其外侧面板 112 的长度略长。正如图 5A 和 5B 所示,在将成一直线对接的两块密封板接合时,只需将两种 I 型铝合金接合构件 120 相对应的公接合部 121a 与母接合部 121b 对接咬合即能实现其快速连接。参考图 6A 和 6B ,可以更容易而直观地理解板与板之间对接的关系,图中面板已被去掉以方便观察接合构件之间的连接关系。
在密封板 110 的直角边位置,水平方向的接合构件 120 与垂直方向的接合构件 120 相互成直角对接。密封板直角两边的接合构件 120 和密封条 160 的对应端部被切成互余的 45 度角,相互对接后由设置于内部的直角连接件 150 将直角两边的接合构件 120 相互连接在一起。直角连接件 150 的结构如图 18A 至 18D 所示,其中,图 18A 为直角连接件 150 的主视图;图 18B 和 18C 为该直角连接件 150 的立体图;图 18D 为该直角连接件 150 的剖视图。直角连接件 150 的宽度方向尺寸比接合构件 120 的内外侧壁之间的距离略小,使两者之间可形成一定的间隙配合,直角连接件 150 的直角两边的长度基本相同。非常有利的方面在于,该直角连接件 150 的一侧表面形成两条相互垂直并连通的沿直角两边长度方向延伸的定位槽 151 ,其另一侧表面形成与接合构件外侧壁 122 的内侧的形状相一致的凸台 152 。连接时,又如图 20A 和 20B 所示意的,先将直角连接件 150 的直角两边分别插入水平方向的接合构件 120 以及垂直方向的接合构件 120 的内外两侧壁之间的空间中,令接合构件 120 上的定位条(未见)插入直角连接件 150 的定位槽 151 中,从而令两个接合构件 120 互为直角地固定对接在一起。
接下来,参考图 9A-9B 为图 4 中所示出的结构部位 II 的放大示意图 , 图 10 为图 4 中所示出的结构部位 III 的放大示意图。在这两种结合部位,其中一侧密封板(如顶板、底板、及前或后侧板)的边缘都采用了一种如图 11A-11B 所描述的 II 型接合构件 120' ,其形状呈' h '形。与 I 型接合构件 120 的结构相类似,它也包括形成有接合部 121' 的接合端,还包括外侧壁 122' 和内侧壁 123' 形成的用于连接密封板 110 的连接端。所不同的地方在于,其接合端为外侧壁 122' 向外水平延伸的一段,并于该延伸段的内侧形成接合部 121' ,如图中所示的较佳实施例为母接合部 121b' ,但在另外的实施例中,该 II 型接合构件 120' 的接合端也可以形成公结合部。也就是说, II 型接合构件 120' 与 I 型接合构件 120 的区别仅在于它们的接合部的开口方向不同,分别与接合构件 120 、 120' 的侧壁延伸方向成 180 度和 90 度。进一步地,图 11A-11B 还详细描述了 II 型接合构件 120' 的结构的剖视图和立体图。与 I 型接合构件 120 的结构相类似,该 II 型接合构件 120' 还包括设在外侧壁 122' 内表面上的楔形卡槽 124' ,以及设其内侧壁 123' 内表面上的定位条 125' ,并且于该内侧壁 123' 的自由端形成 45 度向内的斜缘。作为选项之一,另一个区别在于,取代 I 型构件 120 端面内侧部位的梯形凸榫 126 , II 型构件 120' 的端面内侧部位形成一钩扣 126' 。 II 型接合构件 120' 的整个内侧壁 123' 和钩扣 126' 的形状和大小对应于 II 型接合构件密封条 160' 的内侧形状大小设计,使 II 型接合构件 120' 的整个内侧壁 123' 和钩扣 126' 可被完全包覆在 II 型接合构件密封条 160' 之内。
如图 12 所示,在成直角关系的密封板连接当中,其中一侧密封侧板边缘可采用 I 型接合构件 120 和 I 型密封条 160 ,垂直于第一侧的另一侧密封板的边缘则采用 II 型接合构件 120' 和 II 型密封条 160' ,两者组装之后即如图 13 所示。最后,通过紧固螺栓,可以将其中一块密封板 110 的 II 型接合构件 120' 与垂直的另一块密封板 110 的 I 型接合构件 120 相互固定连接,如图 10 所示,紧固螺栓 180 从 C 形钢底座 20 向上穿过底部密封板的 II 型接合构件 120' 的延伸段以及侧密封板的 I 型接合构件 130 的接合端面,将底座、底板和侧板三者固定连接在一起。
该 II 型接合构件密封条 160' 的结构,参考图 15A 和 15B 所示,与 I 型接合构件密封条 160 相类似,其基本上呈 L 形截面,也包括较长的一段和较短的一段。其较长的一段与 II 型接合构件 120' 的内侧壁 123' 形状大小相配合,且该较长一段自由端的内侧形成有斜槽 161' 对应于内侧壁 123' 的斜缘。其较短的一段与 II 型接合构件 120' 的端面部分形状大小相配合,且于该较长一段内侧形成对应于钩扣 126' 的钩扣槽 162' 。从图中还可以看到,除了与 I 型密封条 160 相类似的挡缘 163' 之外,该 II 型密封条 160' 较短一段的外侧还形成两个相间隔的凸起 164' ,该凸起部 164' 最好是采用较软的材质,其优点在于,在安装之后,该 II 型密封条 160' 的软质凸起 164' 正好紧贴于相邻侧密封板 110 的内侧面板 111 上,起到良好的密封效果。
接下来,参考图 21-23 来介绍密封门与箱体的结构,图 3 中指出的结构部位 IV 为密封门 130 通过 I 型门框构件 140 与前侧密封板 110 之间成一直线对接的结构部位,如放大的图 21 及 / 或图 22 所示,而结构部位 V 则为密封门 130 通过 II 型门框构件 140' 与左侧密封板 110 之间成直角连接的结构部位,如图 23 所示。
首先参见图 21 和 22 所示,密封门板 130 的四周边缘采用了如图 19A 和 19B 所示的 C 形包边套 131 ,一般采用 PVC 材质,并且,优选的是,在该包边套 131 朝向门框的侧面设有软质的凸起 132 。 I 型门框构件 140 配合 I 型门框密封条 170 与 I 型密封板接合构件 120 成一直线相连接。图 21 所示的实施例中所采用的是如图 24A-24B 所示的第一种 I 型门框构件 140 的结构,图 22 所示的实施例中所采用的是如图 25A-25B 所示的第二种 I 型门框构件 140 的结构。
图 21 中所采用的第一种 I 型门框构件 140 的结构,与 I 型接合构件 120 的部分结构相类似,如图 24A 和 24B 所示,包括形成一公接合部 141a 的接合端,以及由内侧壁 142 、外侧壁 143 和左右端壁形成的中空柱体,其内侧壁 142 内表面上形成有一凸台 144 对应于直角连接件 150 的凸台 152 ,其外侧壁 143 内表面上形成有定位条 145 对应于直角连接件 150 的定位槽 151 ,其接合端靠近内侧壁 143 的部分设有一凸榫 146 ,其接合端相对的另一端设有一水平延伸段,形成门框边 147 。图 22 中所采用的第二种 I 型门框构件 140 的结构,与 I 型接合构件 120 的部分结构相类似,如图 25A 和 25B 所示,与第一种 I 型门框构件 140 的结构的差别仅在于其接合端形成一母接合部 141b 。这两种 I 型门框构件 140 的整个内侧壁 143 包括凸榫 146 和门框边 147 形状和大小,对应于一种 I 型门框构件密封条 170 的内侧形状大小设计,其结构如图 16A 和 16B 所示,使该 I 型门框构件 140 的整个内侧壁 143 包括凸榫 146 及延伸段门框边 147 完全包覆在该 I 型门框构件密封条 170 之内。
这种 I 型门框构件密封条 170 的结构如图 16A 和 16B 所示,与 I 型结合构件密封条 160 的部分结构相类似,呈较长的 L 形截面,其较长的一段与 I 型门框构件 140 的内侧壁 143 、凸榫 146 和门框边 147 的形状大小相配合,其较长的一段外端形成一门框边包覆部,其内部定义一容纳门框边 147 的槽 171 ;其较短的一段内侧形成对应于 I 型门框构件 140 的凸榫 146 的榫槽 172 ,相似地,还设有挡缘 173 。特别的是,在该 I 型门框构件密封条 170 的包覆部内侧表面上还设有两个相间隔的软质凸起 174 。
接下来,请参见图 23 ,结构部位 V 是密封门板 130 与侧面的密封板 110 成直角连接的结构部位。这里所采用的是 II 型门框构件 140' , 配合 II 型门框密封条 170' 与 I 型密封板接合构件 120 成直角连接。该 II 型门框构件 140' 的结构如图 26A-26B 所示,其中空柱体及门框边的部分与 I 型门框构件 140 的结构相同,其接合端的部分则与 II 型接合构件 120' 的接合端结构相同。如图所示,它包括形成一母接合部 141b' 的接合端,以及由内侧壁 142' 、外侧壁 143' 和左右端壁形成的中空柱体,其内侧壁 142' 内表面上形成有一凸台 144' 对应于直角连接件 150 的凸台 152 ,其外侧壁 143' 内表面上形成有定位条 145' 对应于直角连接件 150 的定位槽 151 ,其接合端靠近内侧壁 143' 的部分设有一钩扣 146' ,其接合端相对的另一端设有一水平延伸段,形成门框边 147' 。如图中所示的较佳实施例为母接合部,但在另外的实施例中,该 II 型接合构件 140' 的接合端也可以形成公结合部。该 II 型门框构件 140' 的整个内侧壁形状和大小对应于 II 型门框构件密封条 170' 内侧的形状大小设计,使 II 型门框构件 140' 的整个内侧壁 143' 包括钩扣 146' 和门框边 147' 被完全包覆在该 II 型门框构件密封条 170' 之内,其结构参见图 17A 和 17B 所示。
这种 II 型门框构件密封条 170' 的结构,一部分与 II 型接合构件密封条 160' 的相似,另一部分与 I 型门框构件密封条 170 的结构类似,见图 17A 和 17B ,其基本上呈较长的 L 形截面,其较长的一段与 I 型门框构件密封条 170 的完全相同,其内侧形状与对应的门框构件的内侧壁 143 、 143' 和门框边 147 、 147' 的形状大小相配合,其外端也形成一包覆部,于该包覆部内部定义一容纳门框边 147' 的槽 171' ;其较短的一段内侧形成对应于 II 型门框构件 140' 的钩扣 146' 的钩扣槽 172' ,相似地,还设有挡缘 173' 。同样,在该 II 型门框构件密封条 170' 的包覆部内侧表面上还设有两个相间隔的软质凸起 174' 。另外,从图中还可以看到,该 II 型门框构件密封条 170' 较短一段的外侧形成有两个相间隔的凸起 175' ,该凸起部 175' 最好是采用较软的材质,其优点在于,在安装之后,该 II 型门框构件密封条 170' 的软质凸起 175' 正好紧贴于相邻侧密封板 110 的内侧面板 111 上,从而起到良好的密封效果。
当密封门 130 被固定于门框时,如图 21-23 所示,密封门包边套 131 上的软质凸起 132 正好位于该密封条 170 或 170' 两个相间隔的软质凸起 174 或 174' 之间,交错间隔配合形成密封门板 130 与门框 140 、 140' 之间的三重密封。
相对于现有技术来说,本发明具有如下优势:
  • 实现了优化的无冷桥设计,结构简单,容易组合和安装,成本低而效率高;
  • 在无冷桥结构设计基础上,配合新的接合构件及门框构件的设计优化了密封条的结构,强化了密封保护,进一步提高了密封箱体的整体密封性能;
  • 利用直角连接件的定位结构设计,有利地提高了构件之间安装的精度,提高了安装效率。
尽管上面通过举例说明,已经描述了本发明较佳的具体实施方式,本发明的保护范围并不仅限于上述说明,而是由所附的权利要求给出的所有技术特征及其等同技术特征来定义。本领域一般技术人员可以理解的是,在不背离本发明所教导的实质和精髓前提下,任何修改和变化可能仍落在本发明权利要求的保护范围之内。
