交叉引用
本申请引用于2018年11月28日提交的专利名称为“带制冰机的冰箱”的第2018114360000号中国专利申请，其通过引用被全部并入本申请。
技术领域
本公开涉及家用电器技术领域，特别是涉及一种带制冰机的冰箱。
背景技术
目前，用于给制冰机提供冷量的制冰蒸发器通常位于制冰室的内部。由于制冰室外形尺寸不能过大(过大占用容积，且会影响用户正常使用)，制冰蒸发器的外形尺寸也会受限，不能更好的匹配制冰机的热负荷需求，进而影响制冰速度以及制冰量。
同时，较小的制冰蒸发器外形尺寸，会造成制冰蒸发器的有效面积偏小，导致制冰蒸发器的容霜能力差，在实际制冷过程中，需要频繁进入加热除霜以恢复制冰蒸发器的制冷能力。制冰蒸发器的频繁化霜会严重影响制冰机的制冰速度，造成能耗损失；同时会造成储冰桶内的冰块表面温度上升，而引起冰块冻结在一起，影响冰块质量。

本公开的制冰风机5工作时，经制冰送风风道4，将制冰蒸发器7上部的冷空气吸过来，再经制冰送风风道4送到制冰室2内的制冰机3与储冰桶6内，冷空气给制冰机3与储冰桶6制冷后，温度上升，再经制冰回风风道8，回到制冰蒸发器7的底部，再被制冰风机5牵引，经过制冰蒸发器7，同时与制冰蒸发器7进行换热，被制冰蒸发器7冷却过后的空气，再次被制冰风机5牵引进入制冰送风风道4，完成一次送风与回风的制冷循环。
本公开实施例中，所述制冰风道盖板11的内侧设有冷藏箱胆密封板，此处所说的内是相对于冷藏室16而言，指向冷藏室16内的空间为内，背离冷藏室16内的空间为外，所述冷藏箱胆密封板与所述制冰风道盖板11之间留有间隙，形成所述制冰回风风道8，制冰回风风道8位于制冰风道盖板11的内侧，充分利用冷藏箱胆的内表面空间。

当制冰蒸发器请求制冷时，如系统蒸发器没有制冷请求，则控制阀通向制冰毛细管，制冰蒸发器单独制冷，制冰蒸发器可以提供较低的蒸发温度，有利于加快制冰速度；
当制冰蒸发器请求制冷时，如系统蒸发器也请求制冷，则控制阀通向系统毛细管，系统蒸发器与制冰蒸发器同时制冷；既可以满足系统蒸发器的制冷需求，也可同时让制冰蒸发器进行制冷；
当制冰蒸发器不请求制冷时，如系统蒸发器请求制冷，则控制阀通向系统毛细管，系统蒸发器制冷，同时控制制冰风机关闭，虽然制冰蒸发器内部流过制冷剂进行制冷，但由于制冰风机为关闭状态，制冰蒸发器没有向制冰室制冷，此时，制冰蒸发器仅起到连接系统蒸发器与回气管的作用；
当制冰蒸发器没有请求制冷时，如系统蒸发器也没有请求制冷，则控 制阀向不变，整个制冷系统停止制冷；
或，如图5所示，经过所述系统蒸发器后的所述第一分支管路与所述回气管连通，经过所述制冰蒸发器后的所述第二分支管路与所述回气管连通，系统蒸发器与制冰蒸发器形成纯并联的方式。当制冰蒸发器请求制冷，且系统蒸发器也请求制冷时，则控制阀通向系统毛细管，系统蒸发器制冷，此时，可以使系统蒸发器提供相对较高的蒸发温度，提升系统效率，降低能耗；

当制冰蒸发器请求制冷，且系统蒸发器不请求制冷时，如此时制冰机请求制冰，则控制阀通向第一制冰毛细管，制冰蒸发器制冷，此时，可以调整第一制冰毛细管的规格，让制冰蒸发器提供相对较低的蒸发温度，提高制冰速度；
当制冰蒸发器请求制冷，且系统蒸发器不请求制冷时，如此时制冰机不请求制冰，则控制阀通向第二制冰毛细管，制冰蒸发器制冷，此时，可以调整第二制冰毛细管的规格，让制冰蒸发器提供相对较高的蒸发温度， 制冰蒸发器制冷仅维持制冰室温度即可，提高系统效率，降低能耗；
当制冰蒸发器无制冷请求，且系统蒸发器有制冷请求时，则控制阀通向系统毛细管，系统蒸发器制冷，此时，可以使系统蒸发器提供相对较高的蒸发温度，提升系统效率，降低能耗；
