Description

本发明涉及一种冷空气供给导槽装置，该装置用鼓风机强制循环，将蒸发器的冷空气分流，供入一个冷冻室和一个冷藏室，具体涉及一种冷空气供给导槽装置，防止将湍流的冷空气涡流带入冷藏室，而在不使用冷藏室时，将层流的冷空气送入冷冻室。
在电冰箱的传统冷空气供给导槽装置中，导槽装置有一闸门，当冷藏室不使用时，闸门将冷空气吸入通道关闭。
参看图1及图2，将蒸发器4产生的冷空气，用导槽装置1的鼓风机5，分流吹入冷冻室的进气通道6和冷藏室的进气通道7。冷冻室与冷藏室都使用时，将减速系统8中的一控制板9打开，将进入进气通道7的冷空气供给冷藏室3，进入进气通道6的冷空气供给冷冻室2。不需使用冷藏室3时，将控制板9关闭，使进气道7中的冷空气回流，通过进气道6供给冷冻室2。上述结构在美国专利第4，614，092号有详细介绍。
然而，由控制板关闭的进气通道7，是一个封闭的窄通道。进入封闭窄通道的冷空气成为湍流，在进气通道7成螺旋形，回流到一个吸入腔10，使吸入腔10中的冷空气成为涡流。涡流对鼓风机5有阻力，增加电冰箱的负荷，而减小鼓风机5的旋转力，从而使鼓风机5失去平衡，造成导槽装置中的噪音。
鉴于上述问题，本发明的目的是提出一种冷空气供给导槽装置，将进气通道7的进口阻挡，使吸气腔10中的冷空气是层流流动。
本发明的另一目的，是提出一种导槽装置，由于冷空气在吸入腔中是层流，减小对涡流流动的阻力，并减小电冰箱的负荷，从而提高鼓风机5的旋转力。
本发明的另一目的，是提出一种导槽装置，可减小涡流的阻力，使鼓风机平衡旋转，从而降低噪音。
本发明冷空气供给导槽装置，利用鼓风机的强制循环，将蒸发器的冷空气分流吹入一冷冻室和一冷藏室，有一闸门套，闸门套有吸入腔的第一外壁，包围鼓风机部分，有一其顶端与第一外壁顶端一体形成的内壁，有第二外壁面向第一外壁，使鼓风机处在第二外壁与第一外壁之间，两外壁互相对齐，一闸门有一控制推钮安装在上面，用控制推钮推动闸门，推钮夹在内壁和第一外壁之间。一开槽有一在第二外壁末端形成的肩台，和横过第二外壁开槽的内侧，开槽内容纳闸门的下端部。
由于闸门的特点为其结构可造成冷空气的层流，吸入腔中的冷空气沿有特殊表面特征的第一外壁，闸门，与第二外壁流过，从而吸入腔内有层流发生。

图2为现有冷空气供给导槽装置的立体图。
图3为本发明冷空气供给导槽装置的立体图。
图4为本发明闸门件的立体图。
图5为闸门将冷空气吸入件打开的前视图。
图6为闸门将冷空气吸入件关闭的前视图。
图7为安装在电冰箱中的本发明的装置的局部透视图。
图3显示本发明实施例冷空气供给导槽装置11。导槽装置有一鼓风机5，将蒸发器的冷空气分流，引入一冷冻室和一冷藏箱，一个吸入腔10有鼓风机5安在中心上，第一外壁12和第二外壁18包围鼓风机5部分，一冷藏室进气道7和一冷冻室进气道6，分别向冷藏室及冷冻室供给冷空气，一个内壁17其顶端与第一外壁12的顶端一体形成，闸门套13有吸入腔10的第一外壁12围绕鼓风机5部分，并有内壁17，内壁17顶端与第一外壁12的顶端形成一体，第二外壁18面向第一外壁12，使鼓风机5处在第二壁18与第一壁12之间，外壁12和18互相对齐，一有控制推钮16的闸门15安装在上面，用推钮16推动，推钮16放在内壁17与第一外壁12之间，一开槽14有在第二外壁18下末端形成的肩台，和横过外壁18开槽的内侧，开槽内容纳闸门15的下端部。
进气道6，进气道7，鼓风机5，吸入腔10和第二外壁18为与先有技术相似的部件，故略去不作叙述。
内壁17的曲率中心与半径与第二外壁18相同。内壁17的上端与进气道6的底壁21及第一外壁12的顶端连为一体，下文中将叙述。
内壁17从进气道6的底壁21上伸出，伸到进气道7的第一进口壁22的附近。第一外壁12的曲率中心与内壁17相同。第一外壁的曲率半径大于内壁17的曲率半径。与第一进口壁22一体连接的第一外壁12，从底壁21伸到进气道7的第一进口壁22。闸门套13与内壁17与第一外壁12的曲率中心相同。闸门套13的曲率半径小于第一外壁12的曲率半径，长度预定，但大于内壁17的曲率半径长度。
闸门套13在第一外壁12与内壁17之间，形成封闭的底壁21，在第一进口壁22的部分开口，从底壁21向第一进口壁部22全长延伸，有均匀的预定间隙。
在进气道7第二进口壁23上形成开槽14，曲率半径与闸门套13相同，均匀的预定间隙与闸门套相同，有预定深度的开槽容纳闸门15的端部，下文中将有说明。
图4显示本发明的闸门15。
闸门15有预定的厚度，可在闸套13中滑动，闸门15的曲率半径与中心和闸门套13相同，并且闸门15的宽度与内壁17，第一外壁12及第二外壁18等的宽度相同。因此，可将闸门15的端部20放在槽14内，推动闸门15用的推钮16，用螺纹安装在闸门上滑动部的一个预定位置上。有上述特点的闸门15插在闸门套13中滑动。
图5及图6为前视图，显示闸门15的开闭状态。
同时使用冷冻室及冷藏室时，将控制推钮沿图5中的逆时针方向移动，于是将冷空气分流送入进气道7及进气道6。
仅使用冷冻室时，将控制推钮沿图6中的顺时针方向移动，于是闸门15将进气道7阻挡，将送入进气道7的冷空气沿闸门15与第二外壁18的结构，供入进气道6。
并且，需将要求量的冷空气，送入要求容积的冷藏室时，将控制推钮16放到图7所示的冷藏后壁上的冷却程度上，如“最高”，“停”等，从而达到冷藏室中的要求的状态。
在本发明中，闸门阻挡进气道的进口，防止冷藏室进气道中发生涡流，并防止鼓风机旋转阻力及电冰箱的负荷增高，于是鼓风机的旋转平衡，噪声降低。并且，供给的冷空气的量，取决于冰箱的要求的状态。
