Description

一种旋转射流吹吸式涡旋吸油烟机 技术领域
本发明涉及一种吸油烟机，尤其是涉及一种旋转射流吹吸式涡旋吸油烟机。
背景技术
对于家庭及餐饮行业来说，目前，厨房内普遍安装的油烟机是一种能将烹饪过程中产生的油烟迅速抽走排到室外，而净化厨房环境的厨房电器，主要分为顶吸式油烟机和侧吸式油烟机。传统吸油烟机的吸油烟过程为点汇式抽吸，以负压吸气流作为控制气流，吸气口轴线上的速度随着控制点距离增大而衰减极快,有效吸气作用距离和吸气范围较小，导致油烟吸净率比较低。现有的顶吸式和侧吸式油烟机存在以下目前还未解决的缺点：
1、单纯以点汇式抽吸形式的负压吸气型油烟机使用时的油烟吸净率较低，一般只有60％-80％，未排出的油烟污染物对室内环境造成污染，危害使用者的身体健康；
2、一般油烟机的离心风机功率在160-260W之间，耗电量大，而通过加大离心风机功率来提高风量以实现较好的吸油烟效果的，导致出现油烟机更高耗能和更大噪音；
3、传统的吸油烟机因采用大功率的离心风机，工作时风噪声较大，尤其是使用一段时间后，油污在离心风机叶片上的不均匀粘积，造成离心风机的叶片动平衡变差，从而引起油烟机更大的噪音和抖动；
4、顶吸式油烟机因为需要较大的拢烟范围而造成尺寸较大，且有方形棱角，使用者在烹饪时容易碰头撞痛，而为了避免碰头把油烟机安装较高位置时，又容易产生油烟分散现象，油烟吸净率更低；
5、侧吸式油烟机离燃气灶炉盘过近，会将燃气灶火苗吸歪，使部分燃气燃烧产生的热能被油烟机吸走，浪费燃气，而且一旦吸入火苗，有引燃油烟机内的油污导致火灾发生的安全隐患。

一种优选方案，密封旋转盘驱动电机使环槽密封旋转盘与环齿密封固定盘之间有微小间隙，在凸型密封齿与凹型密封槽之间形成迷宫密封。
一种实施方案，旋转射流上罩和旋转射流下罩同轴固定安装在所述的环槽密封旋转盘的底面上。
一种优选方案，所述的旋转射流上罩具有上小下大的圆锥筒型特征，同轴固定安装在环齿密封固定盘的底面上。
一种优选方案，所述的旋转射流下罩具有上小下大的圆锥筒型特征，下端筒壁位开有按同轴心依次均匀排列的导烟射流喷口，每个孔口与旋转射流圈上的条缝导流槽同位对应，导烟射流喷口的射流指向为中心轴水平方向。

4)因所述的旋转射流吹吸式涡旋吸油烟机的底部具有较小尺寸的圆盘形状，因此不易碰头；
5)因沿纵向轴线气旋龙卷风吸气作用距离较远，因而可安装在炉具较高处位置，可使厨房更整洁美观；
6)因设有静电式油雾净化器，因而可大幅减少油烟排放对环境的影响，具有良好的环保意义。

具体实施方式
为使本发明的目的、方案以及有益效果更加清楚明了，下面结合附图和实施例对本发明作进一步说明。
在发明实施例的描述中，需要理解的是，术语“上”、“下”、“顶面”、“底面”、“内圈”、“外圈”等指示的方位或位置关系为基于图1、图2、图3所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
请结合图1至图7所示，本发明提供的一种旋转射流吹吸式涡旋吸油烟机，是由进气增压风机1、排烟离心风机2、进气均流均压筒3、中心吸气管6、密封旋转盘驱动电机7、环齿密封固定盘8、环槽密封旋转盘9、旋转射流上罩10、旋转射流下罩11、旋转射流圈12、射流约束罩17、电机控制电路模块18、电源开关19、静电油雾净化器21、导油管22、集油盒23、机罩壳24、安装支架25组成，所述的进气增压风机1固定安装在机罩壳24上，进气增压风机1的排风口连接进气均流均压筒3上的进气均流均压筒进气口4，密封旋转盘驱动电机7同轴固定安装在环齿密封固定盘8上，密封旋转盘驱动电机7的输出轴由联轴器30同轴连接环槽密封旋转盘9，旋转射流圈12设置在旋转射流下罩11与旋转射流上罩10之间的间隙层中，所述旋转射流下罩11底沿与旋转射流上罩10底沿持平，且容置于旋转射流上罩10内；射流导烟槽16设置在旋转射流下罩11底部，排烟离心风机2的进风口与进气均流均压筒3上口固定连接，并与进气均流均压筒3形成集油腔5。
所述的进气增压风机1是用于提高排入空气的压力并排送到进气均流均压筒3内，空气在进气增压风机1的高速旋转作用下，空气压力被提高并排送到进气均流均压筒3内，高压空气排入进气均流均压筒3后，进入的进气紊流在进气均流均压筒3内进行风量和风压的均匀分布，为向下流入旋转射流下罩11与旋转射流上罩10之间的旋转射流圈12上的条缝导流槽13提供均匀稳定的射流气流。
所述的进气增压风机1提供的高压空气排入进气均流均压筒3后，流通过环齿密封固定盘流通开口26及环槽密封旋转盘流通开口27，继续向下排送到环槽密封旋转盘9下底面安装的旋转射流下罩11与旋转射流上罩10之间的风道中，在经过旋转射流圈12上的条缝导流槽13后，高压空气被分成两路排送，一路由所述风道内的旋转射流圈12的条缝导流槽13由条缝射流喷口14射出，另一路由所述导烟射流喷口15射出。
排入的高压空气经旋转射流上罩10与旋转射流下罩11之间的条缝导流槽13分别引流到条缝射流喷口14纵下方向射出、导烟射流喷口15向轴心方向水平射出，在由密封旋转盘驱动电机7带动的环槽密封旋转盘9的高速旋转状态下，旋转射流形成油烟机下部漩涡气流的水平旋转切向速度。
由进气增压风机1提供的漩涡气流的水平旋转切向射流配合中心轴区域的旋转吸气流，产生向上旋吸的龙卷风气旋涡场效果，在射流与吸气流的联合作用下的轴线吸气作用距离增加,且吸气具有定向性，因此用较小的排风量即可有效将位于下方的烹饪过程中产生的油烟迅速向中心汇聚抽走外排，从而可有效克服油烟仅靠自身热浮升力上升和横向气流对油烟上升的扰动问题，进而达到理想的排烟效果，有效地净化厨房环境。
作为优选方案，所述的进气增压风机1固定在机罩壳24内部，所述进气增压风机1的进风口与油烟机外部空间相连通。
所述的排烟离心风机2是用于吸排风，以使吸油烟中心轴区域为负压。所述排烟离心风机2的蜗壳上部与静电式油雾净化器21接口连接，蜗壳下部与进气均流均压筒3同轴连接。
集油腔5内壁喷涂有特氟龙涂层，在油烟螺旋上升到集油腔5内时，在离心力的作用下，大颗粒的油脂被甩向集油腔5内壁，累积后的液体油污可通过导油管22流到集油盒23中。
所述中心吸气管6按同轴心设置在环槽密封旋转盘9的下底面中心。
所述的密封旋转盘驱动电机7同轴固定安装在环齿密封固定盘8上，密封旋转盘驱动电机7的输出轴由联轴器30同轴固定连接环槽密封旋转盘9，环齿密封固定盘8底面与环槽密封旋转盘9顶面之间存在微小的间隙距离，环槽密封旋转盘9可以无摩擦的自由转动。
所述的环齿密封固定盘8具有圆板形状，平面上开有3个贯穿的环齿密封固定盘流通开口26，作为高压空气的空气流道，下底面设有6个按同轴心依次均匀排列的环状的凸型密封齿28，在环齿密封固定盘流通开口26两侧各设3个，且环齿密封固定盘8中心开有大于密封旋转盘驱动电机7的输出轴直径的孔。
所述的环槽密封旋转盘9具有圆板形状，平面上开有3个贯穿的环槽密封旋转盘流通开 口27，上顶面上设有6个按同轴心依次均匀排列的环状的凹型密封槽29，在环槽密封旋转盘流通开口27两侧各设3个，且环槽密封旋转盘9中心开有大于密封旋转盘驱动电机7的输出轴直径的孔。环状的凸型密封齿28顶面径向尺寸略小于环状的凹型密封槽29的径向尺寸，装配完成后，环状的凸型密封齿28与环状的凹型密封槽29之间存在间隙，在凸型密封齿28与凹型密封槽29之间形成迷宫密封，以对被密封空气流体通过曲折迷宫的间隙时产生节流效应而起密封作用，阻止由进气均流均压筒3进入的正压气流泄漏到大气中，同时阻止正压气流向集油腔5下部负压区域泄漏。
作为优选，所述环齿密封固定盘8、所述环槽密封旋转盘9可以互换。
所述的旋转射流上罩10具有上小下大的圆锥筒型特征，下端具有喇叭口形状，固定安装在环槽密封旋转盘9下底部。
所述的旋转射流下罩11具有上小下大的圆锥筒型的特征，由上到下具有纵向向外倾斜15～20°的角度，旋转射流下罩11下部内侧位开有按同轴心依次均匀排列的导烟射流喷口15，每个孔口与旋转射流圈12上的条缝导流槽13同位对应，导烟射流喷口15的射流为向中心轴水平方向。所述旋转射流下罩11底沿与旋转射流上罩10底沿持平，且容置于旋转射流上罩10内，射流导烟槽16设置在旋转射流下罩11底部。所述的旋转射流下罩11的筒壁、旋转射流上罩10的筒壁、射流导烟槽16的筒壁互为平行，所述筒壁向外倾斜角度都为优选为15～20°。基于康达效应，上述设计可使在旋转射流下罩11范围内所有上升的飘散油烟都被引流向中心轴负压区域。
所述旋转射流圈12设置在旋转射流下罩11与旋转射流上罩10之间的间隙层中，在旋转射流圈12上设有沿着圆周方向间隔均匀分布的18～24个条缝导流槽13(本实施例中设为24个)，其中12个按同轴心依次均匀排列的贯通的条缝状的条缝导流槽13，12个为不贯通的条缝状的条缝射流喷口14，条缝射流喷口14的射流方向为向纵下，12个条缝射流喷口14导流槽位作为与旋转射流下罩11侧壁部位的导烟射流喷口15位置对应。
所述的旋转射流圈12的条缝导流槽13为矩形细条缝，该结构对风道内气流具有一定的良好的导向和加速作用，且气流阻力小，可使出口气流加速，以用于形成较强的旋转风幕。
作为优选方案，所述的射流导烟槽16设置在旋转射流下罩11底部下沿。
所述的射流约束罩17下沿低于旋转射流下罩11和旋转射流上罩10的下沿，这样可形成效果更好的旋转风幕，同时也能避免射流喷射到使用者。
所述的静电式油雾净化器21可根据静电场正负电吸附原理使细小的油雾粒子随气流进 入高压电场中带上正电。当带正电粒子到达净化器收集盘间的负电场时，正电油雾粒子受负电金属盘的吸引而粘附到金属盘上，从而使得油雾与空气分离，累积后的液体油污通过导油管22流到集油盒23中，从而达到油烟净化效果，以减小油烟排放对环境的影响，保护大气环境。
当电源开关19打开开机后，由电机控制电路模块18同时启动进气增压风机1、密封旋转盘驱动电机7和静电油雾净化器21，排烟离心风机2延时20-40秒后启动。所述的密封旋转盘驱动电机7驱动环槽密封旋转盘9，使固定安装于环槽密封旋转盘9上的旋转射流上罩10和旋转射流下罩11的共同旋转，条缝射流喷口14和导烟射流喷口15，射流导烟槽16的射流和内圈中心旋转吸气流共同形成复合向上吸气气流为控制气流，使由进气增压风机1排入的具有一定风压的空气在条缝射流喷口14喷射时旋转起来，射出的空气流体形成的旋转射流不仅有纵向速度，而且还有径向力和切向力。随着旋转射流气旋向下部的台面延伸，配合中心部的旋转吸气流共同产生龙卷风气旋涡场效果。在射流与吸气流的联合作用下的轴线吸气作用距离增加，且吸气具有定向性，因此用较小的排风量即可有效将烹饪过程中产生的油烟迅速汇聚抽走外排，能够做到真正的符合家庭烹饪需求的净化厨房环境的抽油烟机。在需要进行吸尘、有害物捕集的工厂均可使用本发明提供的一种旋转射流吹吸式涡旋吸油烟机。
最后需要附加说明的是，本发明不应该被理解为仅限于以上所描述的实施方式，而是应该被理解为覆盖了本发明权利要求结合说明书揭示内容而确定的所有可能的实施情况。因此，凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化及修饰，均属于本发明技术方案的保护范围。
