具体实施方式
下面结合附图和实施例，对本公开的具体实施方式作进一步详细描述。以下实例用于说明本公开，但不用来限制本公开的范围。
在本公开的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本公开中的具体含义。
实施例1：
如图1至图6所示，图中示意性地显示了该冰箱包括冷藏室和设置在该冷藏室内的制冰室。当然，在该冰箱的内部还可以设有冷冻室和变温室等间室，对于冰箱的具体形式不做具体限定，可以是上面为冷藏室，下面是两个间室的十字对开门冰箱等等。
在该制冰室内设有制冰机1，该制冰室由制冰制冷系统供冷，该制冰制冷系统包括制冰蒸发器2、制冰送风风道3、制冰风机4和制冰回风风 道5，该制冰送风风道3与该制冰回风风道5呈并排式设置，该制冰蒸发器2设置在该冷藏室内并位于该制冰室的外部，该制冰蒸发器2通过该制冰送风风道3和该制冰回风风道5与该制冰机1连通并形成制冷循环回路。具体地，制冰蒸发器2的冷气通过制冰送风风道3由制冰风机4送入制冰机1的内部，冷气传递到制冰机1内后，会与制冰机1内的空气进行热交换，热交换后的冷气由制冰回风风道5送回到制冰蒸发器2内，重新进行热交换，依次循环。
制冰风机4的设置，能够加快冷气流动速度，加快制冷循环，提高制冷效率。
本公开由于将制冰蒸发器2设置在冷藏室内并位于该制冰室的外部，通过使得制冰送风风道3和制冰回风风道5均与制冰机1相连，制冰蒸发器2中的如下所述的化霜加热管10远离了制冰室以及制冰室内的储冰桶，减少了制冰蒸发器2加热除霜时往制冰室内的传热，特别是往储冰桶内的传热，避免了储冰桶的冰块在加热除霜时冰块表面融化，进一步地，有效地提高了制冰效率。
此外，由于冷藏室内的空间远大于制冰室2的空间，从而便于制冰蒸发器2的安装和便于增大制冰蒸发器2的有效面积，更合理的匹配制冰机1的热负荷与制冰蒸发器2的面积，提高制冰机1的制冰速度，提高制冰蒸发器2的容霜能力，降低制冰蒸发器2的加热除霜频率，减小能耗，提升冰块表面质量。
本公开在冰箱的冷藏室内分别设有制冰机1与制冰蒸发器2，通过设置在该制冰室背部的制冰风机4将冷气经较短的制冰送风风道3输送到制冰室中的制冰机1的内部进行制冰，冷量在途中损失较小，制冰效率得到保证。
另外，由于申请中的制冰送风风道3与制冰回风风道5在冷藏室内并排排布，因而，可以使制冰送风风道3与制冰回风风道5做薄，减小冰箱冷藏室内的占用空间，增大冰箱的可用容积。
在本申请的实施例中，该制冰送风风道3与制冰回风风道5的位置可以进行互换，也就是说，该制冰送风风道3可以位于该制冰回风风道5的左侧，也可以位于该制冰回风风道5的右侧。
如图1和图2所示，为进一步优化上述技术方案中的冰箱，在上述技术方案的基础上，该冰箱还包括设置在该冷藏室内的冷藏制冰风道，该冷藏制冰风道包括从前至后依次设置的风道前盖板6、风道泡沫7以及风道后盖板8，其中，在该风道泡沫7和该风道后盖板8之间构造有制冰回风风道5，该风道前盖板6设置在冷藏箱胆9的后侧壁的外侧面。具体地，该冷藏制冰风道可以为如下所述的冷藏送风风道13、冷藏回风风道、制冰送风风道3以及制冰回风风道5所共用。由此可见，这便大大地提高了结构件间的通用性，节省了安装空间、节省了原材料、降低了制作工艺难度。
需要说明的是，本申请的制冰送风风道3和制冰回风风道5的左右两侧以及下侧可通过风道后盖板8与冷藏箱胆9进行固定，该制冰送风风道3和制冰回风风道5的上侧可通过如下所述的制冰机后盖板113进行固定，实现制冰制冷系统中的制冰送风风道3和制冰回风风道5与冷藏室的密封，避免制冰制冷系统中的冷气窜入到冷藏室内。进一步地，避免影响冷藏室内的正常温度，确保冷藏室的正常工作。
如图3和图5所示，在本申请的一个实施例中，在该风道后盖板8和该冷藏箱胆9的后侧壁之间构造有该制冰送风风道3，在该制冰送风风道3内安装有该制冰蒸发器2。具体地，在该风道后盖板8与冷藏箱胆9的后侧壁之间会形成有风腔，该制冰送风风道3属于风腔中的一部分。通过将制冰蒸发器2设置在制冰送风风道3内，从而可以便于将制冰蒸发器2内的冷气经该制冰送风风道3直接、快速地输送到制冰室内的制冰机1的内部，以便于使制冰机的冰格内的水快速地转变为全固态的冰块，大大地提高了制冰效率。
如图3所示，为进一步优化上述技术方案中的冰箱，在上述技术方案的基础上，该冰箱还包括设置在该制冰蒸发器2的下方并靠近该制冰送风风道3和该制冰回风风道5的外侧的化霜加热管10。需要说明的是，在进行化霜工作时，可使化霜加热管10的热量同时传递到制冰进风风道3与制冰回风风道5中进行化霜，避免制冰回风风道5发生冰堵的情况。
另外，由于制冰送风风道3与制冰回风风道5呈并列式排布，因而，有效地减少了与制冰机1的密封配合面，使得密封结构更加的简单、可靠。
如图1、图2、图3、图4和图5所示，在本申请的另一个实施例中， 该制冰送风风道3和该制冰回风风道5均位于该制冰蒸发器2和该制冰机1之间。
该制冰风机4通过制冰风机座16设置在该制冰送风风道3和该制冰回风风道5之间。该制冰风机座16的设置，能够提高制冰风机4的固定强度和固定稳定性，避免制冰风机4发生掉落的情况。
在该制冰机1内构造有制冰内风道1a，该制冰送风风道3、该制冰内风道1a以及该制冰回风风道5依次连通并形成该制冷循环回路。这样，就可以将冷气持续不断地传送到制冰机1的内部，与制冰机1内的空气进行换热，从而达到给制冰机1的内部进行降温的目的，使得制冰机1的冰格中的水能够尽快地转变为全固态的冰块，提高制冰效率。
如图2所示，为进一步优化上述技术中的冰箱，在上述技术方案的基础上，该冰箱还包括设置在该制冰机1的后侧并能将该制冰机1的内部进行密封的盖板组件11，该盖板组件11包括从前至后依次设置的制冰机前盖板111、制冰机后盖泡沫112以及制冰机后盖板113。需要说明的是，该制冰机前盖板111、制冰机后盖泡沫112以及制冰机后盖板113可通过螺钉的方式紧固为一体，然后将整体安装在该制冰机1的后侧，实现对该制冰机1的内部的密封。
该制冰蒸发器2安装在该冷藏箱胆9的后侧壁的外侧面。具体地，该制冰蒸发器2可通过螺钉等紧固件固定安装在该冷藏箱胆9的后侧壁的外侧面。
如图2所示，在另一个实施例中，图中还示意性地显示了该冰箱还包括设置在该冷藏室内的冷藏制冷系统，该冷藏制冷系统包括冷藏蒸发器12、冷藏送风风道13、冷藏风机14和冷藏回风风道，其中，在该风道泡沫7和该风道后盖板8之间构造有该冷藏送风风道13，该冷藏风机14将冷风引流到该冷藏送风风道13内。该冷藏制冷系统是为冷藏室进行制冷的，确保冷藏室的温度能够一直可以保持在恒定的状态，冷藏室内的温度可为零上5度。
由此可见，本申请的给冷藏室进行制冷的冷藏制冷系统与为制冰机1进行制冷的制冰制冷系统是相互独立并且不连通的两套独立制冷系统。因而，在制冰的过程中，完全不会影响到冷藏室内的温度，可以确保冷藏室 的正常使用。
在该风道后盖板8和该冷藏箱胆9的后侧壁之间构造有该冷藏回风风道。也就是说，该冷藏回风风道是属于由冷藏箱胆9的后侧壁和风道后盖板8所构成的风腔的一部分。
在一个实施例中，该风道前盖板6和该风道后盖板8通过螺钉安装在该冷藏箱胆9的后侧壁的外侧面上。也就是说，该风道前盖板6和风道后盖板8为可拆卸式连接，并通过螺钉或铆钉紧固在冷藏箱胆9的后侧壁的外侧面上。
如图4、图5和图6所示，在本申请的一个实施例中，在该制冰送风风道3中，该风道泡沫7与该制冰机后盖泡沫112通过第一配合面3-9-2进行凹凸咬合密封。
该风道后盖板8与该制冰机后盖板113通过第二配合面5-10-2进行前后搭接密封。
该风道泡沫7与该冷藏箱胆9通过第三配合面3-13-1进行下部密封。
该风道后盖板8与该冷藏箱胆9通过第四配合面5-13-1进行左侧螺钉的固定密封。
在另一个实施例中，在该制冰回风风道5中，该风道泡沫7与该制冰机后盖泡沫112通过第五配合面3-9-1实现凹凸咬合密封。
该风道泡沫7与该制冰机后盖板113通过第六配合面3-10-1进行搭接密封。
该风道后盖板8与该制冰机后盖板113通过第七配合面5-10-1进行前后搭接密封。
该风道后盖板8与该冷藏箱胆9通过第八配合面5-13-2进行右侧海绵的密封。
需要说明的是，上述第四配合面5-13-1的形成，可以有效地防止制冰制冷系统中的冷气窜入到冷藏进风风道13中，造成冷藏蒸发器12发生结霜的情况。
上述第八配合面5-13-2的形成，可以防止冷气窜入到冷藏室内，进一步地，避免冷藏室内的温度过低，造成冷藏室的温度无法保持在合适的范围内，从而影响冷藏室的正常工作的情况。
还需要说明的是，上述第一至第八配合面5-13-2的形成，均是为了起到密封的作用，防止冷气发生泄露的情况，即，防止冷气在冷藏制冷系统和制冰制冷系统间发生互窜的情况，同时，防止冷气向冰箱外部发生泄露的情况。这样，便大大地提高了制冰效率以及有效地确保了冰箱的冷藏室内的制冷效率。
综上所述，制冰蒸发器2的冷气通过制冰送风风道3由制冰风机4送入制冰机1的内部，冷气传递到制冰机1内后，会与制冰机1内的空气进行热交换，热交换后的冷气由制冰回风风道5送回到制冰蒸发器2内，重新进行热交换，依次循环。
制冰风机4的设置，能够加快冷气流动速度，加快制冷循环，提高制冷效率。
本公开由于将制冰蒸发器2设置在冷藏室内并位于该制冰室的外部，通过使得制冰送风风道3和制冰回风风道5均与制冰机1相连，制冰蒸发器2中的如下所述的化霜加热管10远离了制冰室以及制冰室内的储冰桶，减少了制冰蒸发器2加热除霜时往制冰室内的传热，特别是往储冰桶内的传热，避免了储冰桶的冰块在加热除霜时冰块表面融化，进一步地，有效地提高了制冰效率。
此外，由于冷藏室内的空间远大于制冰室2的空间，从而便于制冰蒸发器2的安装和便于增大制冰蒸发器2的有效面积，更合理的匹配制冰机1的热负荷与制冰蒸发器2的面积，提高制冰机1的制冰速度，提高制冰蒸发器2的容霜能力，降低制冰蒸发器2的加热除霜频率，减小能耗，提升冰块表面质量。
本公开在冰箱的冷藏室内分别设有制冰机1与制冰蒸发器2，通过设置在该制冰室背部的制冰风机4将冷气经较短的制冰送风风道3输送到制冰室中的制冰机1的内部进行制冰，冷量在途中损失较小，制冰效率得到保证。
另外，由于申请中的制冰送风风道3与制冰回风风道5在冷藏室内并排排布，因而，可以使制冰送风风道3与制冰回风风道5做薄，减小冰箱冷藏室内的占用空间，增大冰箱的可用容积。
以上该仅为本公开的较佳实施例而已，并不用以限制本公开，凡在本 公开的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
