冰箱风道结构、冰箱冷藏风道、冰箱冷冻风道和冰箱 技术领域
本发明涉及冰箱及其制造技术领域，具体地涉及冰箱风道结构、冰箱冷藏风道、冰箱冷冻风道和冰箱。
背景技术
随着科学技术的进步，冰箱逐渐向大容积、薄壁化趋势发展，相比同尺寸普通发泡层厚度冰箱，有效容积更大、性价比较高的冰箱越来越受消费者的青睐。
大容积的冰箱对冰箱各零部件的要求更高，例如冷藏风道/冷冻风道的体积更小、盖板更薄且强度更高。但是现有的冷藏风道/冷冻风道由多个子件组装而成，图1是现有技术中的冰箱冷藏风道的结构示意图，如图1所示，将盖板组装完成后再通过人工将冷藏箱胆5在进风口6处进行拼接密封，形成风道流路，而盖板又包括金属盖板1、塑料盖板2、泡沫风道3、密封海绵4，由此可见，现有的冰箱冷藏风道具有以下缺点：(1)子件多、装配复杂，自动化效率低；(2)风道与箱胆通过卡扣配合，在流通运输过程中局部易脱落；(3)风道组件与冷藏箱胆在拼接处存在密封不良导致的漏冷，进而造成冷藏室底部结冰。
图2是现有技术中的冰箱冷冻风道的结构示意图，如图2所示，现有的冰箱冷冻风道由冷冻胆1、冷冻送风口2、送风风道4、冷藏进风口7、冷藏箱胆6、冷藏回风口8、回风管5(也可以是EPS泡沫风道)、冷冻回风口3组成，且回风管5结构复杂，由多个件拼接而成，拼接处均需要密封，还会导致冷冻室出现凝露和结霜现象。
CN102287990A公开了一种冰箱及其内胆，但是该冰箱的冷藏内胆向冰 箱内凹陷，占用了冰箱的容积，此外，由于该冰箱冷藏内胆的凹槽较大，这就要求凹槽盖板必须有一定的厚度以保证其强度。
发明内容
本发明的目的是为了克服现有技术存在的冰箱冷藏冷冻风道的子件多、装配复杂、制冷效果差且有效容积小的问题，提供冰箱风道结构、冰箱冷藏风道、冰箱冷冻风道和冰箱。
为了实现上述目的，本发明第一方面提供一种冰箱风道结构，包括一体化成型在冰箱箱胆上的凹槽及盖设在所述凹槽上的盖板围合而成，
所述的凹槽连通送风风道，包括一主路凹槽及与其连通的若干支路凹槽，所述的若干支路凹槽间隔布置在所述的冰箱箱胆上；
所述盖板上设有通孔供冷风流入冰箱的箱体内。
优选地，所述的支路凹槽有两个，分别为平行间隔布置的第一支路凹槽和第二支路凹槽。
优选地，所述第一支路凹槽的导风方向与所述主路凹槽的导风方向一致，所述的第二支路凹槽与所述主路凹槽之间设有一倾斜凹槽供冷风流通。
优选地，所述倾斜凹槽的槽长方向与所述主路凹槽的槽长方向的夹角为20°-80°。
优选地，所述第一支路凹槽和第二支路凹槽的截面积之比为0.7:1-1.5:1。
优选地，所述冰箱箱胆的侧部设有一沉槽供所述盖板搭靠。
优选地，所述盖板的厚度为0.5mm-3mm。
本发明第二方面提供一种冰箱冷藏风道，包含前述的冰箱风道结构。
优选地，位于盖板上的通孔的孔径自主路凹槽方向逐渐向支路凹槽方向变大。

本发明第四方面提供一种冰箱，其具有冷藏内胆和冷冻内胆，所述的 冷藏内胆内设有前述的冰箱冷藏风道；和/或所述冷冻内胆内设有前述的冰箱冷冻风道。
通过上述技术方案，具有以下技术效果：
(1)通过盖板与箱胆吸塑凹槽自然形成冰箱风道结构，降低冷藏风道以及冷冻风道的装配子件，使得风道装配时操作步骤简单；
(2)取消了传统风道与送风口的箱内拼接操作，减少了因密封不良而导致的漏冷，降低了冷藏室底部以及冷冻室结冰的风险；

具体实施方式
以下结合附图对本实用新型的具体实施方式进行详细说明。应当理解 的是，此处所描述的具体实施方式仅用于说明和解释本实用新型，并不用于限制本实用新型。
在本发明中，在未作相反说明的情况下，使用的方位词如“上、下、左、右”通常是指参考附图所示的上、下、左、右；“内、外”通常是指相对于各部件本身的轮廓的内外；“远、近”通常是指相对于各部件本身的轮廓的远近。
如前所述，本发明第一方面提供一种冰箱风道结构，包括一体化成型在冰箱箱胆上的凹槽5及盖设在所述凹槽5上的盖板1围合而成，
所述的凹槽5连通送风风道，包括一主路凹槽50及与其连通的若干支路凹槽，所述的若干支路凹槽间隔布置在所述的冰箱箱胆3上；
所述盖板1上设有通孔11供冷风流入冰箱的箱体内。
本发明通过吸塑时在冰箱箱胆3的后方吸出凹槽5，该凹槽5能够和盖板1围合形成风道结构，一方面取消了传统风道与送风口的箱内拼接操作，减少了子件的数量，装配简单；另一方面，由于减少了拼接件的数量，能够减少漏冷的风险，还能够增大冰箱的有效容量。
本发明中，支路凹槽的数量至少有两个，例如可以是2个、3个、4个、5个或者更多，为了合理分配分量兼顾降低凹槽的成型难度，优选条件下，所述的支路凹槽有两个，分别为平行间隔布置的第一支路凹槽51和第二支路凹槽52。
在本发明的一些优选实施方式中，可以通过调整第一支路凹槽51和第二支路凹槽52中的风量使冷风均匀的分布在箱胆3内，本发明通过两种途径调整进入第一支路凹槽51和第二支路凹槽52的风量，(1)通过调整第一支路凹槽51和第二支路凹槽52与主路凹槽50槽长方向的夹角，(2)通过调整第一支路凹槽51和第二支路凹槽52与主路凹槽50连通部分的截面积。
根据本发明，优选条件下，所述第一支路凹槽51的导风方向与所述主 路凹槽50的导风方向一致，所述的第二支路凹槽52与所述主路凹槽之间设有一倾斜凹槽53供冷风流通。进一步优选地，所述倾斜凹槽53的槽长方向与所述主路凹槽的槽长方向的夹角为20°-80°，优选为30°-50°，最优选为35°。
根据本发明，优选条件下，所述第一支路凹槽和第二支路凹槽52的截面积之比为0.7:1-1.5:1，更优选为0.9:1-1.1:1，最优选为1:1。
根据本发明，为了使所述盖板1能够完全围合所述凹槽5，优选地，所述冰箱箱胆的侧部设有一沉槽供所述盖板1搭靠，从而能够在装配时，将所述盖板1限定在所述沉槽内，避免盖板1的移动，同时还可以减小盖板1与箱胆的配合间隙，提高箱胆的保温性能。
本发明的发明人发现，如果凹槽5的截面积太大，且凹槽5中没有支撑件时，那么就要求盖设在所述凹槽5上的盖板1具有高强度，一般情况下采用加厚的板材，例如厚度为3.5mm或有加强筋结构的板材。
根据本发明，由于本发明提供的凹槽5由多个支路凹槽组成，多个支路凹槽之间形成了凸台(相对于凹槽)，所述凸台与冰箱内胆在同一平面上，能够对盖板1起到支撑作用，因此，盖板1无需采用高厚度高强度的板材，采用常规的盖板即可，优选地，所述盖板的厚度为0.5mm-3mm，更优选为0.5mm-2mm，即可以降低盖板的成本，也可以降低盖板的体积，进一步增大冰箱的有效容积。
本发明中，对所述盖板的种类没有特殊的要求，可以是用于冰箱内胆的常用材质，例如可以是塑料盖板，也可以是金属盖板。为了进一步提高所述冰箱内胆的保温性能，优选条件下，所述盖板1包括面板和保温层，所述保温层的种类可以为所属领域技术人员所知，例如可以为海绵。
本发明中，所述风道结构的装配方法简单，例如所述装配方法可以包括以下步骤：
(1)将保温层粘接在面板的背部(面板表面为外观面)上，制得盖板 1，将盖板1送到产线后，由机器人进行抓取作业；
(2)在箱胆后背和/或盖板1上四周预先设定位置进行涂胶，按压牢固后完成装配，形成风道结构。
本发明第二方面提供一种冰箱冷藏风道，包含前述的冰箱风道结构。
图5是根据本发明一实施方式的盖板的结构示意图，如图5所示，根据本发明，优选条件下，位于盖板1上的通孔的孔径自主路凹槽50方向逐渐向支路凹槽方向变大，可以调节进入箱胆内的风量，使冷风均匀的进入冰箱内胆各位置。
