图2是图1的A-A剖面示意图；
图3是本发明一具体实施方式中风量调节装置的结构剖视图；
图4是本发明一具体实施方式中送风风道的俯视图。
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做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。
本文使用的例如“上”、“上方”、“下”、“下方”等表示空间相对位置的术语是出于便于说明的目的来描述如附图中所示的一个单元或特征相对于另一个单元或特征的关系。空间相对位置的术语可以旨在包括设备在使用或工作中除了图中所示方位以外的不同方位。例如， 如果将图中的设备翻转，则被描述为位于其他单元或特征“下方”或“之下”的单元将位于其他单元或特征“上方”。因此，示例性术语“下方”可以囊括上方和下方这两种方位。设备可以以其他方式被定向(旋转90度或其他朝向)，并相应地解释本文使用的与空间相关的描述语。
参图1-4所示为本发明冰箱(未图示)的一较佳实施方式。本发明的冰箱包括箱体(未图示)、风道组件10及控制器(未图示)。箱体内限定有冷藏室(未图示)和冷冻室(未图示)。在冷冻室和冷藏室内均设有分别与控制器电性连接的温度传感器(未图示)。
风道组件10包括风道盖板和送风风道，其中，风道盖板包括第一盖板11和第二盖板12，第一盖板11和第二盖板12共同限定出送风风道13，该送风风道13连通冰箱的冷藏室和冷冻室。故，送风风道13又包括冷藏室风道131和冷冻室风道132。
进一步地，在冷冻室风道132还设有风机15，风机15将冰箱蒸发器(未图示)所产生的冷气吹出，并沿送风风道13通过冷藏室和冷冻室的出风口吹出以实现冷藏室和冷冻室的制冷。风量调节装置14穿设于风道组件上，风量调节装置14靠近风机15设置。
作为一优选的实施方式，风量调节装置14包括调节件141、风门142及与控制器电性连接的电磁阀143。具体地，调节件11设于第一盖板11的外侧，电磁阀143设于第二盖板12的外侧，风门142设于送风风道13中。风门142包括一转动轴1421和与转动轴1421固定的挡片1422，其中，第一盖板11上设有第一安装孔111，调节件141的一端穿过第一安装孔111与转动轴1421的一端插接，第二盖板12上设有第二安装孔121，电磁阀143的一端穿过第二安装孔121与转动轴1421的另一端插接。第二盖板12外侧还设有一用来收容电磁阀143的收容部16。用户手动旋转调节件141即可带动风门142在送风风道13内转动以调节送往冷藏室的风量，并进而驱动电磁阀143接通或断开，控制器被设置为根据电磁阀143反馈的位置信号及冷冻室内的温度传感器反馈的温度信号控制压缩机的启停，使得冷冻室的温度逐渐趋近于冷藏室的温度。优选地，电磁阀143为继电器。
调节件141带动风门142转动，风门142在转动过程中至少具有二个预设位置。在本实施方式中，风门142在转动过程中具有四个预设位置。用户可通过调节件141将风门142从一个预设位置旋到另一个预设位置，优选地，在第一盖板11上与调节件141对应的位置设有刻度表(未图示)，相邻的两个预设位置之间的旋转角度为30度，当然，在本发明的其他实施方式中，两个预设位置之间的旋转角度可以为任意的合适的角度。在本实施方式中，调节件为旋钮，旋钮在从一个预设位置旋转到另一个预设位置的的过程中没有停顿，只有到达用户想要预设位置时才停止旋转。
继续参图4所示，四个预设位置从冷藏风道131到冷冻风道132的方向上依次对应调节件141的“强”档位、“中”档位，“弱”档位和“转换”档位。当调节件141位于“强”档位时，冰箱的冷冻室制冷效果最强，冷藏室温度相对较高；当调节件141位于“中”档位时，冰箱的冷冻室制冷效果较强，冷藏室温度相对较合适，此档位为初始档位，是用户使用最多的；当调节件141位于“弱”档位时，冰箱的冷冻室制冷效果最弱，冷藏室温度相对较低；当档位为“强”、“中”、“弱”时，电磁阀143均位于断开状态，其向控制器反馈位置信号，告诉控制器，此时是冷藏＝冷冻室状态。当调节件141继续旋转并位于“转换”档位时，电磁阀143位于接通状态，其向控制器反馈位置信号，告诉控制器，冷冻室开始加热，并且冷冻室将按照低温冷藏室运行，冷藏室温度正常，控制器会根据冷冻室的温度传感器反馈的温度信号控制冰箱压缩机的启停，使得冷冻室的温度逐渐趋近于冷藏室的温度，以实现冷冻室转换成为冷藏室。
上文所列出的详细说明仅仅是针对本发明的可行性实施方式的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施方式或变更均应包含在本发明的保护范围之内。
