技术领域
本发明涉及空调技术领域，特别涉及一种空调及其室内机、蒸发器、蒸发器管板。
背景技术
现有的蒸发器左塑料管板起着固定蒸发器以及连接蒸发器与骨架的作用，蒸发器左塑料管板与发卡管相配合。蒸发器左管板位于蒸发器的左端。
通常，蒸发器分为两段式蒸发器与三段式蒸发器(两段与三段分别指蒸发器翅片的段数)，对应的蒸发器左塑料管板上，也分为不同的区域与蒸发器发卡管相配合。对于三段式蒸发器，对应的左塑料管板上设置三块区域，分别是上部区域，中间区域，下部区域。每一区域部分开设发卡管容纳腔，用于容纳与固定发卡管部分，每一区域的发卡管容纳腔与单根发卡管相匹配且只能适应一种发卡管的装配，其角度及尺寸与单根发卡管完全匹配。
其中，发卡管的插入方式是由整个系统的分流来决定的。然而，现有的左塑料管板的通用性差，只能对应一种插接方式，也就是说只能适用一种或者抽管后的分流方案；当系统的分流方案发生改变时，这就需要新开左塑料管板，这无疑会拉长其的设计周期，同时也会增加其的设计费用与开模费用。
发明内容
有鉴于此，本发明提供了一种蒸发器管板，能够使得蒸发器管板适应多种插接方式，进而也可兼容多种分流方式，以此大大提高了蒸发器管板的通用性和灵活性，从而当分流方式发生改变时，蒸发器管板无需新开，可大大缩短了产品设计周期，同时也节 约了模具设计与开模费用。

具体实施方式
本发明公开了一种蒸发器管板，其通用性较强，可以适应多种分流方式，灵活性较高且可以缩短新设计塑料管板的周期，有利于缩短产品设计时间，同时也无需新增设计费用与开模费用，具有一定的经济优势与时间优势。
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例提供的蒸发器管板，如图1所示，包括：管板本体1000；
管板本体1000包括：灵活容纳区域；灵活容纳区域设有容纳槽，容纳槽的至少第一对相对的侧壁之间的距离大于或等于发卡管弯曲部位的长度尺寸，容纳槽的至少第二对相对的侧壁之间的距离大于或等于发卡管弯曲部位的长度尺寸。如图13所示，发卡管弯曲部位的长度尺寸L＝发卡管两平行管轴心距+单管直径。
在本方案中，不难理解的是，在容纳槽的第一对相对的侧壁之间容纳发卡管弯曲部位成为一种发卡管弯曲部位的容纳姿态(第一种容纳方式)，在容纳槽的第二对相对的侧壁之间容纳发卡管弯曲部位成为另一种发卡管弯曲部位的容纳姿态(第二种容纳方式)，也就是说容纳槽至少有两种容纳方式，其可至少用于容纳两种不同的发卡管弯曲部位。如此一来，本方案的容纳槽能够适应多种插接方式，从而可适应于多种分流方式，其通用性较强、灵活性较高。此外，管板本体1000的功能区域包括：上部区域和下部区域；或者上部区域、中间区域和下部区域；其中，灵活容纳区域可位于功能区域中的一个子区域，或者功能区域的全部子区域。
从上述的技术方案可以看出，本发明实施例提供的蒸发器管板中，发卡管弯曲部位至少有两种容纳方式，可分别对应容纳在第一对相对的侧壁之间和第二对相对的侧壁之间，也就是说容纳槽能够至少容纳一个发卡管弯曲部位，且其的容纳方式至少有两种；本方案如此设计，则使得容纳槽能够适应于多种插接方式，进而也可兼容于多种分流方式，如此一来，可大大提高了蒸发器管板的通用性和灵活性，继而使得当分流方式发生改变时，蒸发器管板无需新开，从而可大大缩短了产品设计周期，同时也节约了模具设计与开模费用，具有一定的经济效益。此外，本方案适用于蒸发器左管板，特别适用于蒸发器左塑料管板。
进一步地，由上述方案可知，发卡管弯曲部位可容纳在容纳槽不同的相对侧壁之 间，以便于实现发卡管弯曲部位在容纳槽的内部容纳；为了拓宽容纳槽的容纳方式，还可以将发卡管弯曲部位容纳在容纳槽的槽边侧壁，以便于实现发卡管弯曲部位在容纳槽的边缘容纳。相应地，容纳槽为多边形容纳槽，多边形容纳槽的若干槽边侧壁的边长大于或等于发卡管弯曲部位的长度尺寸，且相对的槽边侧壁之间的距离大于或等于发卡管弯曲部位的宽度尺寸，如图13所示，发卡管弯曲部位的宽度尺寸D等于单管直径。本方案如此设计，可使得发卡管弯曲部位紧挨着容纳槽的若干槽边侧壁分布，以便于实现容纳槽容纳方式的最大化，从而可进一步提高了容纳槽的通用性。
再进一步地，多边形容纳槽为平行四边形容纳槽1300，平行四边形容纳槽1300的短槽边侧壁的边长大于或等于发卡管弯曲部位的长度尺寸。为了便于更好地理解上述设计，现举例进行说明，如图13所示，平行四边形容纳槽1300的第一短槽边侧壁1310的边长等于斜插发卡管弯曲部位2300的长度尺寸L，也就是说，平行四边形容纳槽1300的第一短槽边侧壁1310的边长也等于固定容纳区域中的容纳腔单体的槽长；本方案如此设计，以使得平行四边形容纳槽1300的每一个槽边侧壁均可用于容纳发卡管弯曲部位，如此一来，可大大拓宽了容纳槽的容纳方式。此外，本方案选用平行四边形容纳槽1300作为容纳槽，还以便于实现斜插发卡管弯曲部位和平行发卡管弯曲部位的边缘容纳。
为了便于理解上述的设计，现以平行四边形容纳槽1300容纳三个发卡管弯曲部位的情况进行说明；具体地，在第一种插接方式中，如图13和图14所示，平行四边形容纳槽1300的第一短槽边侧壁1310用于容纳单根斜插发卡管弯曲部位2300，第一长槽边侧壁1330和第二长槽边侧壁1340远离第一短槽边侧壁1310的一侧用于分别对应容纳第一平行发卡管弯曲部位2100和第二平行发卡管弯曲部位2200；
或，在第二种插接方式中，如图15和图16所示，平行四边形容纳槽1300的第二短槽边侧壁1320用于容纳单根斜插发卡管弯曲部位2300，第一长槽边侧壁1330和第二长槽边侧壁1340远离第二短槽边侧壁1320的另一侧用于分别对应容纳第一平行发卡管弯曲部位2100和第二平行发卡管弯曲部位2200。
在本方案中，容纳槽的侧壁设有用于同发卡管弯曲部位配合的容纳槽弹性定位结构，如此一来，以便于实现发卡管弯曲部位的弹性定位和固定的作用，以达到快速定位和防止发卡管弯曲部位发生容纳晃动的效果。
具体地，容纳槽弹性定位结构包括：
开设于容纳槽的侧壁的容纳槽弹性通孔；
设置于容纳槽的侧壁的容纳槽弹性舌，容纳槽弹性舌末端位于容纳槽弹性通孔内；
设置于容纳槽弹性舌的末端内壁的容纳槽定位凸。本方案如此设计，以便于实现了对发卡管弯曲部位的快速定位，以及对发卡管弯曲部位在轴线方向(垂直方向)的弹性卡紧作用，从而以便于达到快速容纳和容纳紧固的效果。为便于更好地理解上述的容纳槽弹性定位结构，现还是以平行四边形容纳槽1300容纳三个发卡管弯曲部位的情况为例进行说明：
在第一种插接方式中，如图13所示，平行四边形容纳槽1300的第一长槽边侧壁1330(靠近其第二短槽边侧壁1320的一侧)开设有第一弹性通孔(倒凹形结构)，第一长槽边侧壁1330设有第一弹性舌1331(如图5所示)，且第一弹性舌1331的末端位于第一弹性通孔内，第一弹性舌1331的末端内壁设有第一楔形定位凸1332(如图4和图5所示)；
在第二种插接方式中，如图15所示，平行四边形容纳槽1300的第二长槽边侧壁1340(靠近其第一短槽边侧壁1310的一侧)开设有第二弹性通孔1343(倒凹形结构)，第二长槽边侧壁1340设有第二弹性舌1341(如图8所示)，且第二弹性舌1341的末端位于第二弹性通孔1343内，第二弹性舌1341的末端内壁设有第二楔形定位凸凸1342(如图10所示)。
进一步地，容纳槽的槽底开设有可视窗口，且可视窗口与容纳槽弹性定位结构相对应设置。更为具体地，该容纳槽为平行四边形凹槽；
平行四边形内槽的槽底1350(如图7所示)分别开设有第一可视窗口1351(如图2所示)和第二可视窗口1352(如图10所示)，第一可视窗口1351与第一楔形定位凸1332位于同一侧，第二可视窗口1352与第二楔形定位凸1342位于同另一侧。即为第一楔形定位凸1332位于第一可视窗口1351的可视范围内，第二楔形定位凸1342位于第二可视窗口1352的可视范围内。本方案如此设计，以便于工人进行插接方式的快速校对，从而保证生产节拍。比如当为第一可视窗口1351无发卡管，第二可视窗口1352有发卡管的情况(图15)，则说明发卡管的插接方式是斜插管在上(图16)；相反的，如果通过第一可视窗口1351可以看到发卡管，则说明发卡管的斜插管在下面。
在本方案中，管板本体1000还包括：固定容纳区域；固定容纳区域设有多组发卡管容纳腔；每组发卡管容纳腔均包括若干个用于同发卡管弯曲部位对应配合的容纳腔单体；
每组发卡管容纳腔中有一个容纳腔单体包括：侧腔和端盖；侧腔的内壁形状与发 卡管弯曲部位的外侧周面形状配合，侧腔的一端开放用于发卡管弯曲部位出入，另一端由端盖闭合。本方案如此设计，以使得每组发卡管容纳腔中有一个容纳腔单体为封顶腔体，进而以便于通过封顶腔体实现对发卡管弯曲部位弯部的限位，以起着固定发卡管弯曲部位并以防其发生左右位移(沿发卡管轴向的位移)的作用。如图7所示，管板本体的下部区域设有一个封顶的斜插发卡管容纳腔单体，和四个漏空的平行发卡管容纳腔单体。
进一步地，如图1所示，固定容纳区域设有上部发卡管容纳腔组1100、中部发卡管容纳腔组1200和下部发卡管容纳腔组1400；每组发卡管容纳腔包括：斜插发卡管容纳腔单体和平行发卡管容纳腔排；其中，中间区域的发卡管容纳腔只包括：平行发卡管容纳腔排；
平行发卡管容纳腔排包括：至少内外两排平行发卡管容纳腔，每排平行发卡管容纳腔包括：至少两个平行发卡管容纳腔单体；斜插发卡管容纳腔单体和平行发卡管容纳腔单体均为用于同单个发卡管弯曲部位相匹配；即为固定容纳区域内的发卡管容纳腔单体用于同单个发卡管弯曲部位为一一对应匹配；具体地，如图3所示，上部发卡管容纳腔组1100包括：上部平行容纳腔单体1110和上部斜插容纳腔单体1120；中部发卡管容纳腔组1200包括：中部平行容纳腔单体1210；下部发卡管容纳腔组1400包括：下部平行容纳腔单体1410和下部斜插容纳腔单体1420；
在每一个区域中，斜插发卡管容纳腔单体和平行发卡管容纳腔单体两个中的一个为封顶腔体，另一个为漏空腔体。本方案如此设计，以便于通过封顶腔体实现对发卡管弯曲部位弯部的限位，以起着固定发卡管弯曲部位并以防其发生左右位移(沿发卡管轴向的位移)的作用。如图7所示，管板本体的下部区域设有一个封顶的斜插发卡管容纳腔单体，和四个漏空的平行发卡管容纳腔单体。
进一步地，容纳腔单体设有用于同发卡管弯曲部位配合的容纳腔弹性定位结构，即为每排平行发卡管容纳腔中的一个平行发卡管容纳腔单体设有用于同发卡管弯曲部位(左侧面或右侧面)配合的容纳腔弹性定位结构。本方案如此设计，不仅以便于实现平行发卡管弯曲部位的弹性定位容纳，而且还能以防平行发卡管弯曲部位出现左右晃动，以确保其容纳的平稳性。
再进一步地，容纳腔弹性定位结构包括：
开设于容纳腔单体的侧壁的容纳腔弹性通孔；
设置于容纳腔单体的侧壁的容纳腔弹性舌，容纳腔弹性舌末端位于容纳腔弹性通 孔内；
设置于容纳腔弹性舌的末端内壁的容纳腔定位凸。为了便于更好地理解上述设计，现以平行发卡管容纳腔单体为例进行说明。如图12所示，平行发卡管容纳腔单体的侧壁开设有第三弹性通孔，平行发卡管容纳腔单体的侧壁设有第三弹性舌1421，且第三弹性舌1421位于第三弹性通孔内，第三弹性舌1421的末端内壁设有第三楔形定位凸1422。本方案中的第三弹性舌1421如此设计，以使得其具有左右方向的伸缩余量，然后再配合第三楔形定位凸1422的夹持作用，从而以达到了对平行发卡管弯曲部位的弹性卡紧式的容纳效果。
本发明实施例还提供了一种蒸发器，包括：蒸发器管板，所述蒸发器管板为如上所述的蒸发器管板。由于本方案采用了上述的蒸发器管板，因此其也就具有相应的有益效果，具体可以参照前面说明，在此不再赘述。
本发明实施例还提供了一种室内机，包括：蒸发器2000，所述蒸发器2000为如上所述的蒸发器。由于本方案采用了上述的蒸发器，因此其也就具有相应的有益效果，具体可以参照前面说明，在此不再赘述。
本发明实施例还提供了一种空调，包括：室内机，所述室内机为如上所述的室内机。由于本方案采用了上述的室内机，因此其也就具有相应的有益效果，具体可以参照前面说明，在此不再赘述。
下面结合具体实施例对本方案作进一步介绍：
本发明技术方案的详细阐述：
本发明提出一种蒸发器左塑料管板，其上分为三个区域，分别是上部区域，中间区域与下部区域。
如图17所示，上部区域最多容纳五根发卡管，中间区域最多容纳七根发卡管，下部区域最多容纳五根发卡管。
图1中圈起的地方是灵活容纳区域，采用平行四边形凹槽容纳发卡管，此凹槽与发卡管的匹配可以至少有两种匹配方式(不包含抽管的方式)，如图13和图15所示，即为显示了两种插接方式，也就是可以有两种分流方式，再加上抽管方式，抽一根管的情况下，有6种分流方式，抽2根管的情况下，还有6种分流方式，此左塑料管板理论上可适用的分流方式多达14种分流，通用性大大增加。
进一步地，上部区域与下部区域的发卡管容纳腔主要特点有两个：
1、U型截面封顶腔体；
2、左右定位容纳腔；
其中，上部区域与下部区域的发卡管容纳腔分别可最多容纳5根发卡管，每个区域含四个普通U型截面漏空腔体与一个U型截面封顶腔体，U型截面封顶腔体起着固定发卡管左右位移的作用，此腔体分别设置在最上端与最下端。四个普通U型截面漏空腔体平行分布，分内外两排，每一排有两个发卡管容纳腔，每一排的容纳腔有两种：一个是普通容纳腔，另一个是左右定位容纳腔，内壁设置有楔形定位凸点(即为第三楔形定位凸点)及左右方向的伸缩余量。其中，该楔形定位凸点由外往里沿着与发卡管配合的方向逐渐紧固发卡管。
再进一步地，平行四边形凹槽特点：
1、位置：不局限于设置在中间区域，也可以设置在下部区域与上部区域；
2、容纳数量：可容纳奇数根发卡管，发卡管数量不局限于3根，可以是5根，7根等；如图13或图15所示，本发明以3根发卡管为例，3根发卡管包含1根斜插管，2根平行管。同样的，如果腔体容纳5根发卡管，那么包含1根斜插管，4根平行管；
3、可视窗口：数量为2个，分别贴左/右侧壁，分别称为左上可视窗(第一可视窗口)与右下可视窗(第二可视窗口)；通过此可视窗，可以帮助工人快速判断发卡管的插接方式有没有问题；例如：当左上可视窗无发卡管，右下可视窗有发卡管的情况(图15)，说明发卡管的插接方式是斜插管在上(图16)；相反的，如果通过左上可视窗可以看到发卡管，那么说明发卡管的斜插管在下面。即为此可视窗的作用是方便工人进行插接方式的快速校对，从而保证生产节拍。
4、弹性定位区域及楔形定位凸：在每个可视窗的侧边，设置弹性定位结构，此弹性定位结构可以在两个方向上进行发卡管的弹性定位。图10是在发卡管的垂直方向上设置有第二矩形槽，当塑料管板扣在发卡管上时，此矩形槽对垂直方向的变形设置有弹性余量，从而保证垂直方向的卡紧。图8是发卡管方向上的开槽，此开槽可以对发卡管方向上的弹性变形留有余量。当左塑料管板装配到位后，发卡管顶部带来的变形得以缓解，从而保证发卡管方向上的卡紧。其中，楔形定位凸(第一楔形定位凸点和第二楔形定位凸点分别设置在左右壁的两侧)设置在弹性定位结构的内壁上，楔形定位凸的小端面在外，沿着与发卡管配合的方向逐渐紧固发卡管。此外，在上中下三个区域里，都设置有弹性定位区域及楔形定位凸，其分布规律是每一组发卡管(一行)设置一个，如图3所示。上部区域有3个，中部有2个，下部有2个。
本发明的优点：
本发明提出一种左塑料管板结构，可以兼容多种分流方式，当分流方式发生改变时，蒸发器的左塑料管板无需新开，大大缩短了产品设计周期，同时也节约了模具设计与开模费用，具有一定的经济效益。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
