图1为根据一些实施例的冰箱的整体结构示意图。如图1所示，一种冰箱，包括限定出隔热储藏间室103的箱体；箱体包括内胆101、外壳102及设于内胆101与外壳102之间的保温层；其中，储藏间室103由内胆101围成，内胆101的前端形成取放口104；箱体上设有箱门，以打开或关闭取放口104。内胆101包括与取放口104正对设置的胆后壁。
储藏间室103靠近胆后壁设有主送风风道及位于主送风风道下侧的定向送风风道。其中，主送风风道与定向送风风道能够断开或连通。主送风风道包括位于其上部的导向送风风道、位于其下部的摆风送风风道、位于摆风送风风道的相对两侧的微感送风风道。定向送风风道位于摆风送风风道的下侧。
图2为根据一些实施例的冰箱的送风单元的分解结构示意图；图3为根据一些实施例的冰箱的送风单元的整体结构示意图；图4为根据一些实施例的图3沿A-A方向的冰箱剖视图。如图2所示，导向送风风道内设有多个竖向设置的导向送风口41，导向送风口41处设有第一导风件42，以将冷空气导向送风至储藏间室103顶部，以确保储藏间室103顶部区域的冷却。
摆风送风风道内形成有连通摆风送风风道与储藏间室103的第一风口21及第二风口22。其中，第一风口21与第二风口22均呈波浪型。在一些实施方式中，第一风口21与第二风口22轴对称；即第一风口21的波峰与第二风口22的波谷相对应，第一风口21的波谷与第二风口22的波峰相对应。以上波浪型的第一风口21与第二风口22形成轴对称的设置，使沿竖直方向第一风口21与第二风口22之间的距离不断变化，从而使通过第一风口21与第二风口22进入储藏间室103内的冷空气相互对流影响，加快气流扰动，加快储藏间室103内的温度均匀化。摆风送风风道内设有具有摆风组件，摆风组件包括摆风板23及用于驱动摆风板23移动的摆风驱动机构；在摆风驱动机构的作用下，摆风板23能够沿波浪型风口的波长方向往复移动，控制第一风口21与第二风口22的有效出风面积，以对储藏间室103的主体空间进行摆动送风，有效加快储藏间室103内的气流流动，实现迅速降温。
微感送风风道内设有多排的微孔出风口32，以将微感送风风道内的气流 梳理后送入储藏间室103。微感送风风道对摆风送风风道起辅助送风作用，并改善摆风送风风道两侧局部区域的温度均匀性。
定向送风风道设于摆风送风风道的下侧，且定向送风风道与设于储藏间室103内的变温室等特定控温或控湿的储藏装置相连通，以对其进行定向送风。
本公开的一些实施例，导向送风风道位于微感送风风道上侧，且导向送风风道与微感送风风道的下端始终保持连通，有效确保气流流动的流畅性。通过将主送风风道分为多个送风区，以进行区域差别化送风，并确保送风流畅。
图5为根据一些实施例的冰箱的送风单元另一视角的整体结构示意图。参考图1-图5所示，主送风风道与定向送风风道通过第一连通口11a相连通；摆风送风风道内的摆风板23移动以打开或封堵第一连通口11a。
具体的，冰箱内设有冷却风道，冷却风道内设有蒸发器，以对经过冷却风道的空气进行降温。需要说明的是，对于现有具有冷藏室与冷冻室的冰箱，对于单个蒸发式制冷系统的冰箱，冷却风道设于冷冻室的后侧；对于具有两个蒸发式制冷系统的冰箱，送风风道及冷却风道均设于冷藏室的后侧。
当摆风板23移动至第一连通口11a的位置时，摆风板23封堵第一连通口11a，摆风送风风道与定向送风风道断开时，经过冷却风道的冷空气进入定向送风风道，并通过定向送风风道向储藏间室103内送风；当摆风板23移动离开第一连通口11a时，主送风风道与定向送风风道相连通，经过冷却风道的冷空气进入定向送风风道，一部分通过定向送风风道向储藏间室103送风，另一部分通过第一连通口11a进入主送风风道，并由摆风送风风道、微感送风风道、导向送风风道其中至少一个由储藏间室103的后侧对储藏间室103进行横向与纵向的全方位送风。
在一些实施方式汇总，胆后壁上设有送风单元9，送风单元9包括风道盖板91、位于风道盖板91与胆后壁之间的风道板93；风道盖板91靠近取放口104一侧设有匀温板92。
其中，风道板93上形成有位于其底部的定向风区1、位于定向风区1上部的主风区。风道板93下部设有与定向风区1相对应的背板7，背板7与位于风道板93下部的定向风区1配合共同限定出定向送风风道；风道板93的主风区与胆后壁相配合，并与胆后壁共同限定出主送风风道；定向送风风道与主送风风道通过第一连通口11a相连通。其中，风道板93与胆后壁之间设有环绕主风区的密封条94，以使风道板93与胆后壁密封连接。在一些可能的实施方式中，风道板93设置为泡沫件，其成型简单，且具有保温效果。
具体的，风道板93上设有用于分隔主风区与定向风区1的第一隔板11，第一连通口11a形成于第一隔板11上。
风道板93上于主风区内设有竖向的第二隔板12及第三隔板13、横向的连接第二隔板12与第三隔板13的上端部的顶隔板14；第二隔板12、第三隔板13、顶隔板14共同限定出摆风风区2；第二隔板12与第三隔板13的下端 与第一隔板11之间的区域形成有过渡区5，且第二隔板12的下端部与第三隔板13的下端部共同限定出第二连通口15。其中，第一连通口11a与第二连通口15在竖向正对设置。第二隔板12、第三隔板13及顶隔板14将主风区位于过渡区5以上的区域分隔为摆风风区2、位于摆风风区2相对两侧的微感风区3，及位于顶隔板14上侧的导向风区4。
其中，过渡区5与定向风区1通过第一连通口11a相连通，且过渡区5与摆风风区2通过第二连通口15相连通，过渡区5与微感风区3通过第三连通口16相连通。在一些实施方式中，过渡区5与微感风区3始终相连通；
波浪型的第一风口21及第二风口22设于摆风风区2内，且第一风口21与第二风口22轴对称。本实施例中，第一风口21与第二风口22呈正弦型；正弦型的第一风口21与第二风口22设置能够增强对气流横向和纵向的扰动效果，加快储藏间室103内的温度均匀化。另外，在一些实施方式中设置的第一风口21与第二风口22长度为正弦波的一个波长，例如波浪型的第一风口21及第二风口22均呈S型。
参考图2和图5所示，背板7的顶部形成有安装座71；摆风驱动机构包括固定于安装座71上的摆风电机24。在一些实施方式中，摆风电机24设置为步进电机；摆风电机24安装于背板7上的安装座71上。摆风电机24的输出轴上设有第一齿轮25，第一齿轮25相邻位置设有与之相啮合的第二齿轮26，第二齿轮26连接有螺杆27。摆风电机24工作，并带动第一齿轮25转动，第一齿轮25与第二齿轮26相啮合，并带动第二齿轮26轮动，第二齿轮26带动螺杆27旋转。通过设置第一齿轮25与第二齿轮26的传动比，能够控制螺杆27的转动快慢，从而控制摆风板23的移动速度。
图7为根据一些实施例的冰箱的摆风板的结构示意图。参考图2和图7所示，摆风板23安装于螺杆27上，且摆风板23上设有与螺杆27相配合的连接螺孔231，摆风电机24工作并带动螺杆27旋转运动，在螺杆27的旋转作用下，摆风板23沿螺杆27向上或向上移动。位于摆风风区2上侧的顶隔板14能够有效限定摆风板23的上移极限位置。
在一些实施例中，第一风口21与第二隔板12的最小距离记为L 1，第一风口21与螺杆27的最小距离为L 2，L 1∈[5，10]，L 2∈[5，10]，单位：mm。记第一风口21的波峰靠近第二隔板12，第一风口21的波谷靠近螺杆27，波峰与第二隔板12的距离为L 1，波谷与螺杆27的距离记为L 2。
以摆风板23封堵第一连通口11a的位置记为第一极限位置进行送风说明；具体如下：
摆风板23在第一极限位置时，其封堵第一连通口11a，定向风区1与过渡区5相断开，此时仅通过定向风区1向储藏间室103内进行定向送风。
摆风板23在螺杆27的旋转作用下向上移动，摆风板23移动至第二连通口15时，定向风区1与过渡区5相连通，过渡区5与微感风区3相连通，微感风区3与导向风区4相连通；冷却气流由冷却风道进入定向风区1，然后通过第一连通口11a进入过渡区5；过渡区5内的气流通过第三连通口16进入 位于摆风风区2相对两侧的微感风区3，再由微感风区3进入对应侧的导向风区4。以实现定向风区1、微感风区3及导向风区4同时送风。
摆风板23在螺杆27的旋转作用下由第二连通口15向上移动，摆风板23移动至摆风风区2内时，随着摆风板23向上移动的距离增加，第一风口21与第二风口22的有效出风面积增大，摆风风区2向储藏间室103送入的气流量增加；过渡区5内的冷却气流分流进入微感风区3、摆风风区2；并由微感风区3进入导向风区4；其中，部分冷却气流通过第二连通口15进入摆风风区2，并由波浪型的第一风口21和第二风口22向储藏间室103送风，形成大面积的横向送风效果。此时，定向风区1、摆风风区2、微感风区3、导向风区4同时送风。另外，随着摆风板23的纵向往复移动，由波浪型的第一风口21与第二风口22送出的气流在横向形成摆风效果；并带动其它区域送风的变化，以实现储藏间室103全区域的动态送风效果。
在一些实施例中，如图7所示，摆风板23的横向两端部设有导向孔232，导向孔232内安装有固定连杆28；在摆风板23移动过程中，固定连杆28对摆风板23进行限定和导向，以确保摆风板23运动的有效性。具体的，固定连杆28的上端与顶隔板14固定，固定连杆28的下端与第一隔板11固定连接；两个固定连杆28分居于第一连通口11a的两侧。本实施例中，两个固定连杆28其中之一位于第二隔板12的相邻位置，另一个位于第三隔板13的相邻位置。且固定连杆28不影响微感风区3与过渡区5的连通性。
在一些实施例中，安装座71设于背板7靠近风道板93的一侧。进入定向风道内的气流由安装座71的相对两侧流出。风道板93上设有导风块17，导风块17位于固定于安装座71上的第一齿轮25的上方；导风块17的横截面由下向上逐渐减小，即导风块17呈上窄下宽的样式，以使导风块17避让螺杆27设置；导风块17一方面能够有效遮挡第一齿轮25及摆风电机24，使由定向风道向上流动经过安装座71的空气沿导风块17的侧面流动，对经过安装座71的气流进行整理，然后再汇聚，有效避免经过安装座71后的气流紊乱；并确保由定向风区1进入主风区内的气流稳定性。另一方面，使冷空气由安装座71的侧壁流过，而避开安装座71的上方，有效避免在摆风电机24上方产生冷凝水并滴落于摆风电机24上而影响摆风电机24的性能。导风块17的侧面呈弧形变化，能够更为舒缓地对气流进行整理。
另外，导风块17的上端面与第一隔板11的上端面共面，导风块17能够配合第一隔板11有效限定摆风板23的下移极限位置，在摆风板23与导风块17相抵接时，摆风板23封堵第一连通口11a，断开了定向风区1与主风区的连通。
在一些实施例中，定向送风风道内设有风门组件，风门组件用于控制定向送风风道与冷却风道的连通或断开。其中，风门组件包括风门72及驱动风门72打开或关闭的风门驱动73。具体的，定向送风风道内形成有位于安装座71下侧的收容部，风门驱动73安装于收容部内，以充分利用安装座71的下侧空间；且风门驱动73与安装座71相配合将定向送风风道的气流分流。气 流从风门驱动73和安装座71的侧面流过时，将风门驱动73及摆风驱动机构所产生的热量携带走，确保风门驱动73及摆风驱动机构保持高性能工作，并延长其作用寿命。在一些实施方式中，风道板93设有分居于螺杆27的相对两侧的两个定向送风口10。定向送风风道内设有两个独立控制的风门72，能够单独控制相应侧的定向送风口10与冷却风道的连通与断开，并在风门72打开时通过定向送风风道将冷却气流导向定向送风口10，并通过定向送风口10进入储藏间室103。
图6为根据一些实施例的冰箱的风道板及风门组件的结构示意图。如图6所示，微感风区3内设有气流通道31。在一些实施例中，气流通道31竖向设置；风道盖板91上与气流通道31相对应的区域设有多排微孔出风口32，以使通过气流通道31的气流由微孔出风口32流出进入储藏间室103。具体的，由胆后壁向取放口104的方向，即气流方向，气流通道31呈渐扩式；渐扩式的微感送风风道能够将微感风区3位于气流通道31周围的气流聚集于气流通道31内，然后通过风道盖板91上的微孔出风口32梳理气流，微感风区3内的部分气流通过微孔出风口32进入储藏间室103，其风量小，且风速较低，但具有一定的冷量，能够维持局部区域的温度恒定。在一些实施方式中，气流通道31的横截面呈锥台状，且其靠近取放口104一端的尺寸小于其靠近胆后壁一端的尺寸。风道盖板91上的微孔出风口32的孔径d 1∈[3，5]，单位：mm；相邻两微孔出风口32的间距s 1∈[15，20]，单位：mm。

以上随着导风板的位置不同，各风区的出风量和风速不同，联合作用下，形成差异化送风效果。在使用过程中，随着摆风板23的旋转运动，摆风及微感复合风区30形成摆风及微感送风效果；并带动其它区域送风的变化，以实现储藏间室103全区域的动态送风效果。
本公开另一些实施例与图15-图22所示实施例原理相同，其主要区别在于：仅设置摆风风区2、定向风区1。
图23为根据一些实施例的冰箱的送风单元的整体结构示意图；图24为根据一些实施例的冰箱的送风单元的整体结构示意图。
如图23-图24所示，摆风风区2内设有摆风组件，其结构与实施例四中的摆风组件结构相同，通过旋转对气流进行控制，在此不再赘述。其主要在于摆风风区2内的气流流道设置不同。摆风组件的旋转区域设有多个气流流道，各气流流道一端与摆风组件的旋转区域相连通，另一端与储藏间室103相连通；摆风组件的摆风板旋转运动以将气流送风至与其相连通的各个气流流道。需要说明的是，本实施例以图15-图22所示的实施例为基础进行说明，其实质不局限于图15-图22所示的实施例的摆风组件设置，其亦可选用图2-图21所示实施例中的摆风组件。
具体的，主风区仅设置为摆风风区2。摆风风区2内设有第一分流板81、第二分流板82、第三分流板83、第四分流板84、第五分流板85及第六分流板86。由胆后壁一侧面向风道板93，第一分流板81、第二分流板82、第三分流板83、第四分流板84、第五分流板85及第六分流板86顺时针排布。垂直于风道板93且过摆风电机24输出轴的平面记为纵向中心面M；第一分流板81、第二分流板82及第三分流板83位于纵向中心面M的一侧，第四分流板84、第五分流板85及第六分流板86位于纵向中心面M的另一侧。且第一分流板81、第二分流板82及第三分流板83依次与第六分流板86、第五分流板85及第四分流板84关于纵向中心面M形成轴对称。
第一分流板81、第二分流板82、第三分流板83、第四分流板84、第五分流板85及第六分流板86各自靠近摆风电机24输出轴的一端依次记为第一分流端K 1、第二分流端K 2、第三分流端K 3、第四分流端K 4、第五分流端K 5 及第六分流端K 6。第一分流端K 1、第二分流端K 2、第三分流端K 3、第四分流端K 4、第五分流端K 5及第六分流端K 6均在以O为圆心的同一圆周上。其中，第一分流板81、第二分流板82向上延伸、第三分流板83向下延伸。
对应的，摆风及微感复合风区30内与∠K 1OK 2相对应的区域记为第一流道8a；摆风及微感复合风区30内与∠K 2OK 3相对应的区域记为第二流道8b；摆风及微感复合风区30内与∠K 3OK 4相对应的区域记为第三流道8c；摆风及微感复合风区30内与∠K 4OK 5相对应的区域记为第四流道8d；摆风及微感复合风区30内与∠K 5OK 6相对应的区域记为第五流道8e；摆风及微感复合风区30内与∠K 6OK 1相对应的区域记为第六流道8f。以上第一流道8a、第二流道8b、第四流道8d、第五流道8e、第六流道8f环绕摆风板23的运动区域设置，并与之相连通；第一风板61与第二风板62旋转时，将气流导入以上各流道。
其中，第六流道8f由下向上延伸，第一流道8a与第五流道8e分居于第六流道8f的相对两侧，并向上延伸。第三流道8c向下延伸，第二流道8b与第四流道8d分居于第三流道8c的相对两侧。由胆后壁一侧面向风道板93，第一流道8a、第二流道8b、第三流道8c、第四流道8d、第五流道8e及第六流道8f顺时针分布。其中，第一流道8a、第二流道8b、第四流道8d及第五流道8e内均设有导流片87。导流片87设置为翼型，导流片87的入口角为气流方向；导流片87的出口角θ向上或向下设置；本实施例中，θ∈[30°，50°]。具体的，第一流道8a与第五流道8e内均设置有两个导流片87，且两个导流片87均向上设置；第二流道8b与第四流道8d内均设置有两个导流片87，且其中一个导流片87向上设置，另一个导流片87向下设置。导流片87的设置能够增加侧面出风面积，使气流更均匀地进入储藏间室103。本实施例中，第一流道8a、第二流道8b、第四流道8d及第五流道8e内的导流片87均设于其所在气流流道的靠近出风端的位置。
第一分流板81向上并向其邻近的风道板93的侧壁延伸，第一分流板81的出风端与风道板93的顶壁之间形成第一出风口80a，第一出风口80a的长度记为L` 1；第二分流板82的出风端与第一分流板81的出风端的形成第二出风口80b，第二出风口80b的长度记为L` 2；第二分流板82的出风端与第三分流板83的出风端之间形成第三出风口80c，第三出风口80c长度记为L` 3；第三分流板83的出风端与第一分隔板之间形成第四出风口80d，其长度记为L` 4。L` 2：L` 1∈[1.5，2.5]，L` 2：L` 4∈[1.5，2.5]；L` 3：L` 1∈[1.5，2.5]，L` 3：L` 4∈[1.5，2.5]。本实施例中，设置L` 3＝L` 2＝2L` 1＝2L` 4。以上设置合理分布流道，能够合理分配储藏间室103内的气流。
第一风板61远离摆风电机24的输出轴的一端记为第一自由端B 1，第二风板62远离摆风电机24的输出轴的一端记为第二自由端B 2；其中，OB 1＝OB 2＝OK 1＝OK 2＝OK 3＝OK 4＝OK 5＝OK 6。以使第一自由端B 1或第二自由端B 2能够与第一分流端K 1、第二分流端K 2、第三分流端K 3、第四分流端K 4、第五分流端K 5及第六分流端K 6其中任意一个对接配合，以在第一摆风板61和第二摆风板62旋转过程中，有效地将气流送往其所经过的流道内。
本实施例中，第一分流端K 1、第二分流端K 2、第三分流端K 3、第四分流端K 4、第五分流端K 5及第六分流端K 6用于与第一自由端B 1或第二自由端B 2相配合的端面均设置为弧形；且第一分流端K 1、第二分流端K 2、第三分流端K 3、第四分流端K 4、第五分流端K 5及第六分流端K 6的弧形端面共圆；第一分流端K 1、第二分流端K 2、第三分流端K 3、第四分流端K 4、第五分流端K 5及第六分流端K 6的弧形端面所在圆周与第一自由端B 1或第二自由端B 2的端面运行轨迹圆为同一个圆，以确保第一自由端B 1或第二自由端B 2的旋转运动及其与第一分流端K 1、第二分流端K 2、第三分流端K 3、第四分流端K 4、第五分流端K 5及第六分流端K 6其中任意一个配合。
以上随着摆风组件的导风板所在位置不同，各风区的出风量和风速不同，联合作用下，形成差异化送风效果。在使用过程中，随着摆风板23的旋转运动，摆风及微感复合风区30形成摆风效果，以实现储藏间室103全区域的动态送风效果。
作为另一种可实施的方式，沿第一摆风板61的旋转区域设置有m个流道，则设置m个流道所对应的圆心角为360°/m；对应的∠B 1OB 2＝n*(360°/m)，n整数。其中，∠B 1OB 2≤180°。以上设置，在第一风板61和第二风板62在旋转至其自由端与分流端相配合时，能够封堵或打开流道，从而控制气流所流经的流道。其原理与图15-图22所示的实施例的原理相同，在此不再赘述。例如，设置六个流道，且∠K 1OK 2＝∠K 2OK 3＝∠K 3OK 4＝∠K 4OK 5＝∠K 5OK 6＝∠K 6OK 1＝60°，∠B 1OB 2＝n*60°，n＝1或2或3；第一风板61和第二风板62在旋转至其自由端与分流端相配合时，部分流道被打开通入气流，部分流道被封堵。
需要说明的是，冰箱内的多个储藏间室103包括冷藏室，以上实施中的储藏间室103为冷藏室，送风单元9设于冷藏室的后壁上。
本公开设置多个不同形式的送风风道，并设置多样化的正面出风口。在以上多个实施例中，向储藏间室103送风的出风口设置为不等长直线型或弧形，且送风风道分区域设置不同的出风口形式，增加了储藏间室103的出风面积，减少出风死角。另外，还设置有多个微孔出风口32，实现微孔出风，出风的风道补充。在主送风风道内，设置移动的摆风组件，在摆风驱动机构作用下往复运动，配合出风口结构，实现横向和纵向(上下、左右)摆风以及定向送风。通过本公开的结构设计，减小储藏间室103的温度波动，改善储藏间室103的温度均匀性，还可根据需要在储藏间室103内设置干区或湿区，满足多样化的用户需求。本公开进行分区送风，从而进行差异化和针对性的送风，便于风量和风向的调节，实现精细化存储；并解决了传统冰箱送风方式单一的问题；本公开实现了分区送风、定向送风、微孔送风、摆风等多样化送风方式，达成分区分送、干湿分储、温湿精控的用户体验目标。
以上所述，仅是本公开的较佳实施例而已，并非是对本公开作其它形式的限制，任何熟悉本专业的技术人员可能利用上述揭示的技术内容加以变更或改型为等同变化的等效实施例应用于其它领域，但是凡是未脱离本公开技 术方案内容，依据本公开的技术实质对以上实施例所作的任何简单修改、等同变化与改型，仍属于本公开技术方案的保护范围。
