 具体实施方式
以下将结合附图所示的具体实施方式对本发明进行详细描述。但这些实施方式并不限制本发明，本领域的普通技术人员根据这些实施方式所作出的结构、方法、或功能上的变换均包含在本发明的保护范围内。
参照图1至图5，本发明第一具体实施方式中，冰箱1可以包括门体3、设置于所述门体3的制冰室31、设置于所述制冰室31内的制冰机5，所述制冰室31侧壁设置有进风口32和回风口33，进风口32置于所述制冰机5的一侧。
冰箱1可以包括箱体2。箱体2内部可以设置有冷藏室21和冷冻室，门体3可以是可枢转的设置于箱体2上并用于开闭冷藏室21。冷藏室21的后壁处可以设置有用于向制冰室31供冷的蒸发器室，蒸发器室内可以设置有蒸发器和风扇。
进风口32和蒸发器室之间可以设置有进风风道22，回风口33和蒸发器室之间可以设置有回风风道23。蒸发器室内的冷风经进风风道22从进风口32流入制冰室31，制冰室31内的冷风从回风口33经回风风道23流回蒸发器室。
所述制冰机5进风口32端处设置有挡风件4，所述进风口32可以包括正对所述制冰机5的第一部分以及未被所述制冰机5遮挡的第二部分，所述挡风件4遮挡所述第二部分的至少部分，所述制冰机5侧壁与所述制冰室31侧壁之间形成第一风道34，所述挡风件4与所述制冰室31侧壁之间形成第二风道35，所述第一风道34与所述第二风道35连通。
由于冰箱1门体3大小是受限制的，因而制冰室31空间的大小是有限的。而为了保证能够从蒸发器室向制冰室31输送充足的冷气，进风口32需要满足一定的尺寸大小，且其安装位置还需要配合门体3的其他结构，因而进风口32可能无法完全正对制冰机5设置，从而造成从进风口32未被制冰机5遮挡的部分进入的冷风扩散至制冰室31内而无法向制冰机5供冷，影响制冰机5的制冰效率。
通过设置挡风件4，挡风件4至少部分遮挡未被制冰机5遮挡的第二部分，并和第二部分形成连通制冰机5第一风道34的第二风道35，通过第二风道35的设置能够有效阻挡从进风口32进入的冷风直接扩散至制冰室31内，保证冷风能够充分与制冰机5内水进行热交换，从而提高制冰机5的制冰效率。
制冰机5可以和制冰室31后壁间隔设置，制冰机5后壁可以于制冰室31后壁之间形成第三风道36。第三风道36可以与第一风道34、第二风道35连通。从进风口32进入的冷风可以经第一风道34、第二风道35、第三风道36流经制冰机5的侧壁和后壁处，以实现向制冰机5供冷。
因而，如此设置，能够有效阻挡从进风口32进入的冷风直接扩散至制冰室31内，保证制冰机5的冷量供应，能够提高从进风口进入的冷风的利用率，提高制冰机5的制冰效率，能够增加制冰机5和制冰室31、进风口32、进风风道22等结构的适配性，使同一尺寸的制冰机5能够适用于多种尺寸的制冰室31，实现制冰机5的模块化，降低生产成本。
参照图3至图5，进一步的，在本实施方式中，所述进风口32的前壁相对于所述制冰机5的前壁置于靠近所述制冰室31开口侧，所述挡风件4件至少部分遮挡所述进风口32的前部。
为了有效利用制冰室31的空间，制冰机5一般靠近制冰室31的顶壁及后壁设置，导致制冰机5一般处于制冰室31的上部和后部。为了保证进风口32的尺寸、便于进风口32的设置和形成进风风道22等组件的安装，进风口32可以设置于制冰室31侧壁的中部。
制冰机5可以遮挡进风口32的后部并形成第一风道34，挡风件4可以遮挡进风口32的前部并形成第二风道35。第二风道35和第一风道34连通，从而使从进风口32前部进入的冷风能够经第二风道35进入第一风道34。
如此设置，能够有效阻挡从进风口32进入的冷风直接扩散至制冰室31内，保证制冰机5的冷量供应，提高制冰机5的制冰效率，能够保证进风口32的尺寸大小，同时便于进风口32的设置以及形成进风风道22等组件的安装，能够增加制冰机5和制冰室31、进风口32、进风风道22等结构的适配性。
参照图3至图5，进一步的，在本实施方式中，所述进风口32的下壁置于所述制冰机5下壁的下方，所述挡风件4至少部分遮挡所述进风口32的下部。
由于制冰机5位于制冰室31的上部，进风口32上壁可以靠近制冰室31顶壁的设置。为了保证进风口32的尺寸、便于进风口32的设置和形成进风风道22等组件的安装，进风口32的下壁可以位于制冰机5下壁的下方。
制冰机5可以遮挡进风口32的上部并形成第一风道34，挡风件4可以遮挡进风口32的下部并形成第二风道35，第二风道35和第一风道34连通，从而使从进风口32下部进入的冷风能够经第二风道35进入第一风道34。
如此设置，能够有效阻挡从进风口32进入的冷风直接扩散至制冰室31内，保证制冰机5的冷量供应，提高制冰机5的制冰效率，能够保证进风口32的尺寸大小，同时便于进风口32的设置以及形成进风风道22等组件的安装，能够增加制冰机5和制冰室31、进风口32、进风风道22等结构的适配性。
参照图3至图6，进一步的，在本实施方式中，所述挡风件4可以包括连接于所述制冰室31侧壁的第一挡风板41，所述第一挡风板41自所述进风口32前壁处延伸至所述制冰机5进风口32端的前壁，并至少部分遮挡所述进风口32前部。
挡风件4可以是可拆卸的独立部件。用于固定挡风件4的连接结构可以位于制冰室31的侧壁、顶壁或后壁，当然，也可以位于制冰机5。
第一挡风板41可以与制冰机5前侧相接，以便于第一挡风板41的限位和定位。第一挡风板41可以与制冰室31侧壁相接。第一挡风板41可以沿制冰机5的上下方向竖直设置。第一挡风板41的上端可以高于进风口32的上端，第一挡风板41的下端可以位于第一进风口32下壁的下方，以充分遮挡进风口32。从而保证从进风口32进入的冷风能够流入第一风道34，尽量避免冷风直接扩散至制冰室31。
第一挡风板41的上端可以直接抵接于制冰室31的顶壁，阻挡冷风扩散的同时，能够便于挡风件4的安装，增强挡风件4安装的稳固性，避免防风件晃动。
如此设置，能够有效阻挡从进风口32进入的冷风直接扩散至制冰室31内，保证制冰机5的冷量供应，提高制冰机5的制冰效率，结构简单，安装方便。
参照图3至图6，进一步的，在本实施方式中，所述挡风件4可以包括连接于所述制冰室31侧壁的第二挡风板42，所述第二挡风板42自所述进风口32下壁处延伸至所述制冰机5近风口端的下壁，并至少部分遮挡所述进风口32下部。
第二挡风板42可以与制冰机5下侧相接，以便于第二挡风板42的限位和定位。第二挡风板42可以与制冰室31侧壁相接。第一挡风板41可以沿制冰机5的前后方向水平设置。第二挡风板42的前端可以位于进风口32前壁的前侧，第一挡风板41的后端可以位于进风口32后壁的后侧，以充分遮挡进风口32。从而保证从进风口32进入的冷风能够流入第一风道34，尽量避免冷风直接扩散至制冰室31。
第二挡风板42的后端可以直接抵接于制冰室31的后壁，第二挡风板42的后端也可以设置有插入制冰室31后壁的突起421，制冰室31可以相应的设置有用于容置该突起421的开口，阻挡冷风扩散的同时，能够便于挡风件4的安装，增强挡风件4安装的稳固性，避免防风件晃动。
如此设置，能够有效阻挡从进风口32进入的冷风直接扩散至制冰室31内，保证制冰机5的冷量供应，提高制冰机5的制冰效率，结构简单，安装方便。
参照图3至图7，进一步的，在本实施方式中，所述制冰机5可以包括制冰盘51、设置于所述制冰盘51下方的导风件52、设置于制冰盘51和导风件52之间的加热丝，所述导风件52具有与所述进风口32相对的导风口54，所述挡风件4遮挡所述导风口54外部或所述导风口54设置有防触电格栅。
制冰盘51内部可以容纳用于制造冰块的水，冷气可以和制冰盘51内的水进行热交换从而制造冰块。导风件52可以连接于制冰盘51。导风件52朝向制冰盘51底壁部分可以呈开口设置。
导风件52朝向制冰盘51底壁的开口可以和导风口54相连通形成第四风道37，以使经导风口54进入导风件52的冷风能够吹向制冰盘51的底部，和制冰盘51内的水进行热交换，提高制冰机5的制冰效率。
为了便于制冰盘51脱冰，制冰盘51底壁往往设置有加热丝，加热丝能够将电能转化成热能加热制冰盘51。
为了避免用户因将手伸入导风口54触电，需要在导风口54处设置遮挡。
可以在导风口54处设置网格状的防触电格栅以阻挡用户伸入导风口54内。
由于防触电格栅在一定程度上会阻挡冷气的流通，从而影响制冰机5的制冰效率。因而也可以不在导风口54设置防触电格栅，导风口54为一个整体的无遮挡的贯通口，通过挡风件4遮挡导风口54外部，能够有效阻挡用户伸入导风口54的同时，能够避免影响制冰机5的制冰效率。
如此设置，能够保证向制冰机5的冷量供应，提高制冰机5的制冰效率，保证用户的使用安全，避免用户触电。
参照图2至图5，进一步的，在本实施方式中，所述门体3可以包括设置于所述制冰室31外部的门壳38，所述门壳38与所述制冰室31侧壁间隔有用于填充保温材料保温空间，所述制冰室31侧壁设置有向门壳38凹陷的第一凹陷部311，所述制冰机5部分置于所述第一凹陷部311内。
为了保证制冰机5和制冰室31及门体3的适配，可以通过在制冰室31的侧壁设置向门壳38凸出的凹陷部来为制冰机5提供足够的安装空间，保证制冰机5安装的同时，减少制冰室31对门体3空间的占用，使门体3结构更加紧凑，实现门体3的小型化设计，使制冰机5沿门体3宽度方向的尺寸可以大于制冰间室沿门体3宽度方向的尺寸。
所述进风口32设置于所述第一凹陷部311，所述第一凹陷部311可以包括主壁312、连接于主壁312和制冰室31侧壁之间的倾斜周壁313，所述进风口32至少部分设置于所述第一凹陷部311的周壁313。
周壁313倾斜设置，能够便于第一凹陷部311制造、加工、脱模，也便于制冰机5的安装。
将进风口32设置于周壁313，能够保证进风口32和制冰机5的配合的同时，避免增加第一凹陷部311的尺寸，减少第一凹陷部311对门体3空间的占用。且周壁313朝向制冰机5倾斜，也能够使进风口32自然朝向制冰机5，使冷气向制冰机5的方向流动。
挡风件4的第一挡风板41和第二挡风板42可以和第一凹陷部311的周壁313配合设置并抵接与周壁313，第一挡风板41和第二挡风板42的外缘可以与第一凹陷部311外侧边缘贴合，以便于挡风件4安装限位的同时，实现第一凹陷部311的隐蔽式设置。
参照图4、图5、图7至图9进一步的，在本实施方式中，与所述第一凹陷部311相对的所述制冰室31侧壁设置有向室外凹陷的第二凹陷部314，所述制冰机5部分设置于所述第二凹陷部314内。
所述第二凹陷部314侧所述制冰室31顶壁设置有向室外凹陷的第三凹陷部315，所述制冰机5部分设置于所述第三凹陷部315，所述第二凹陷部314的凹陷深度小于所述第一凹陷部311。
由于制冰机5远离进风口32端一般会设置制冰马达55。制冰盘51上方设置有用于拨动冰块使冰块脱离制冰盘51的翻冰件53。制冰马达55用于驱动翻冰件53转动。
因而设置第二凹陷部314和第三凹陷部315能够有效增大制冰机5的安装空间。由于第二凹陷部314和第三凹陷部315相邻且于第一凹陷部311相对，为了便于凹陷部的加工、制造、脱模，便于制冰机5的安装，第二凹陷部314的深度可以小于第一凹陷部311。
参照图8至图10，进一步的，在本实施方式中，所述门壳38可以设置有与所述进风口32配合的第一开口381，所述进风口32和所述第一开口381之间设置有形成进风风道22的风道件61，所述风道件61可以包括连接于所述第一凹陷部311的连接板62，所述连接板62卡接于所述第一凹陷部311的主壁312及周壁313。
风道件61内部可以设置有用于冷气流通的通道。蒸发器室的冷气可以经第一开口381、风道件61、进风口32进入制冰室31。风道件61可以是中部分体式设置，可以包括设置于进风风道22一侧的第一件63和设置于进风风道22另一侧的第二件64。第一件63和第二件64可以通过螺纹连接件连接，如螺钉。
由于第一凹陷部311的主壁312和周壁313不在同一平面上，为了实现风道件61的稳固安装，连接板62可以和主壁312和周壁313贴合设置，并可以在主壁312和周壁313上向四周延伸。第一凹陷部311的主壁312和周壁313可以设置用于卡接风道件61的连接板62的卡接件316，卡接件316可以卡接在连接板62边缘处。主壁312的卡接件316和周壁313的卡接件316可以位于连接板62的相对侧。
如此设置，能够实现向制冰室31的供冷，能够便于风道件61安装，保证风道件61安装的稳固性。
参照图9至图10，进一步的，在本实施方式中，所述连接板62位于所述保温空间，所述第一凹陷部311设置有遮挡所述连接板62外缘的凸缘317。
由于保温空间内需要填充保温材料，通过在连接板62外缘设置凸缘317，能够防止保温材料自连接缝隙渗入连接板62和凹陷部的之间。
参照图8至图10，进一步的，在本实施方式中，进一步的，在本实施方式中，所述门壳38可以设置有与所述回风口33配合的第二开口382，所述进风口32和所述第二开口382之间可以设置有形成回风风道23的第二风道件65。
第二风道件65可以包括连接于制冰室31侧壁的第二连接板67，第二连接板67与制冰室31侧壁的配合面为平整面。制冰室31侧壁可以设置具有插槽的插接件318，使第二连接板67可以滑动插接于制冰室31侧壁。插接件318可以先自制冰室31侧壁向门壳38延伸然后翻边形成插槽，第二风道件65的第二连接板67边缘可以设置有向门壳38延伸并和插槽配合的突出边66，以实现第二风道件65和制冰室31侧壁的稳固连接。
参照图3、图4、图6，进一步的，在本实施方式中，所述第一挡风板41设置有若干自所述进风口32向所述导风口54倾斜延伸导风筋43。所述挡风件4通过螺纹连接件固定连接于所述制冰室31侧壁。
导风筋43的设置能够引导冷气流向导风口54，提高制冰机5的制冰效率，同时，能够增强第一挡风板41的强度，提高第一挡风板41的使用寿命。挡风件4通过螺纹连接件固定，连接结构简单，便于挡风件4的安装，同时能够保证挡风件4和制冰室31侧壁连接的稳固性。
进一步的，在本发明第二具体实施方式中，其与第一具体实施方式的区别在于第一具体实施方式中的挡风件4可以是独立的零部件，而本实施方式的挡风件4可以由储冰盒7侧壁形成。
参照图2、图4、图7，在本实施方式中，所述制冰机5下方设置有储冰盒7，所述储冰盒7位于所述制冰机5前侧的侧壁向上延伸并至少部分遮挡所述进风口32以形成所述挡风件4。
储冰盒7可以是可取放的设置于制冰室31内。储冰盒7朝向制冰室31底部呈敞开设置，以使制冰机5制造的冰块能够进入储冰盒7。储冰盒7侧壁位于制冰机5前侧的部分上端可以高于进风口32，且可与制冰机5前壁相接，储冰盒7侧壁的前端可以相对于进风口32前壁靠近制冰室31开口。
如此设置，结构简单，制造加工方便，成本低廉，能够有效阻挡从进风口32进入的冷风直接扩散至制冰室31内，保证制冰机5的冷量供应，提高制冰机5的制冰效率。
参照图2、图4、图7，进一步的，在本实施方式中，所述制冰机5下方设置有储冰盒7，所述储冰盒7位于所述制冰机5下方的侧壁向上延伸至所述制冰机5底壁，并至少部分遮挡所述进风口32的下部以形成所述挡风件4。
所述储冰盒7位于所述制冰机5下方的侧壁向上延伸至所述制冰机5底壁相接。如此设置，结构简单，制造加工方便，成本低廉，能够有效阻挡从进风口32进入的冷风直接扩散至制冰室31内，保证制冰机5的冷量供应，提高制冰机5的制冰效率。
综上所述，本发明中的冰箱1，通过在所述制冰机5进风口32端处设置有挡风件4，并和进风口32未被所述制冰机5遮挡部分形成风道，能够解决进风口32的开口位置和制冰机5的安装位置往往存在一定程度的偏差，导致从进风口32进入制冰室31的一部分冷风扩散到制冰室31内而无法吹到制冰机5上，从而影响制冰机5的换热效率的问题。
采用本申请中的技术方案，能够有效阻挡从进风口32进入的冷风直接扩散至制冰室31内，保证制冰机5的冷量供应，能够提高从进风口进入的冷风的利用率，提高制冰机5的制冰效率，能够增加制冰机5和制冰室31、进风口32、进风风道22等结构的适配性，使同一尺寸的制冰机5能够适用于多种尺寸的制冰室31，实现制冰机5的模块化，降低生产成本。
