背景技术Background technique
吸油烟机是常用的厨房设备,在使用过程中,将油烟吸走排除室内。油烟机上通常设有滤网,油烟经过滤网时,油会附着在滤网、电机、以及风叶上。随着油烟机使用时间的增加,附着的油变多,会增加风机系统的负载,使油烟机的工作效率降低。并且由于越来越多的油附着在滤网上,使滤网的实际开孔面积变小,从而增大油烟进入的阻力,使滤网吸风时受力增大,震动增大从而增大了油烟机工作时产生的噪音。Range hoods are commonly used kitchen equipment. During use, the range hoods are sucked out of the room. The range hood is usually equipped with a filter. When the oil fume passes through the filter, the oil will adhere to the filter, motor, and fan blades. As the use time of the range hood increases, more oil is attached, which will increase the load of the fan system and reduce the working efficiency of the range hood. And because more and more oil adheres to the filter screen, the actual opening area of the filter screen becomes smaller, thereby increasing the resistance of oil fume entering, so that the strain on the filter screen increases when the air is sucked, and the vibration increases, thereby increasing The noise produced by the range hood when it is working.
相关技术提出一种新型吸油烟机,将滤网设置成可转动的动态滤网,滤网可受控于驱动机构发生自转,当油烟经过时,油渍附着在转动的滤网上。由于滤网是转动的,因此油渍会受到离心力而沿着滤网的圆周边缘被甩出,不易收集处理。The related art proposes a new type of range hood, in which the filter screen is set as a rotatable dynamic filter screen. The filter screen can be controlled to rotate by a driving mechanism. When oil fume passes by, oil stains adhere to the rotating filter screen. Since the filter screen is rotating, the oil stains will be thrown out along the circumferential edge of the filter screen by centrifugal force, making it difficult to collect and process.
发明内容Summary of the invention
因此,本公开要解决的技术问题在于克服相关技术中油渍被转动的滤网甩出不易收集缺陷,从而提供一种导油环及带有该导油环的吸油烟机。Therefore, the technical problem to be solved by the present disclosure is to overcome the defect that the oil stains are thrown out by the rotating filter in the related art and are not easy to collect, thereby providing an oil guide ring and a range hood with the oil guide ring.

本公开技术方案,具有如下优点:The technical solution of the present disclosure has the following advantages:
1.本公开提供的导油环,包括:集油部,所述集油部设置有环形挡油部,以及与挡油部相连接的引油槽,所述引油槽的入口设于所述集油部的内表面上;连接部,设于所述集油部上并朝向远离所述集油部方向延伸。1. The oil guide ring provided by the present disclosure includes: an oil collecting portion provided with an annular oil retaining portion, and an oil guiding groove connected to the oil retaining portion, and an inlet of the oil guiding groove is provided in the collecting portion On the inner surface of the oil part; the connecting part is arranged on the oil collecting part and extends in a direction away from the oil collecting part.
环形挡油部环绕包围在滤网四周,滤网转动时,油液从滤网上被甩出,油油液被集油部阻挡。集油部为环形,油烟沿集油部的内表面流动汇聚,最终通过引油槽集中流出。环形的集油部具有一定宽度,因此形成两端开口的形状,其中一端开口上设有用于与油烟机连接的连接部。The annular oil retaining part surrounds the filter screen. When the filter screen rotates, the oil is thrown out from the filter screen and the oil is blocked by the oil collecting part. The oil collecting part is annular, and the oil fume flows and converges along the inner surface of the oil collecting part, and finally flows out through the oil guide groove. The annular oil collecting part has a certain width, so it forms a shape with two ends open, and one end of the opening is provided with a connecting part for connecting with the range hood.
2.本公开提供的导油环,还包括:引风翻边,所述引风翻边设于所述集油部远离所述引油槽的一端,所述引风翻边向所述引油槽方向延伸并形成引导油烟的引流通道。2. The oil guide ring provided by the present disclosure, further comprising: a draft flange, the draft flange is provided at an end of the oil collecting part away from the oil guide groove, and the draft flange faces the oil guide groove Extend in the direction and form a drainage channel for guiding oil fume.
集油部上两端开口,引油槽靠近连接部的一端设置,另一端延伸出引风翻边,引风翻边向集油部包围的范围内弯折,并形成一个引导油烟进入集油部范围的引流通道。油烟通过引流通道穿过集油部进入油烟机。The two ends of the oil collecting part are open, the oil guiding groove is set close to one end of the connecting part, and the other end extends out of the wind-inducing flanging. The wind-inducing flanging bends into the range surrounded by the oil collecting part and forms a guide oil fume into the oil collecting part. Range of drainage channels. The oil fume enters the range hood through the oil collecting part through the drainage channel.
3.本公开提供的导油环,所述引流通道的轴向截面面积沿靠近所述连接部的方向逐渐变小。3. In the oil guide ring provided by the present disclosure, the axial cross-sectional area of the drainage channel gradually decreases in the direction close to the connecting portion.
由于滤网与集油部之间留有一定间隙,滤网受控于电机转动,油烟尽可能的通过滤网进行过滤。因此引流通道引导油烟向滤网中心方向聚拢,减少油烟未经过滤而从滤网和集油部之间的间隙穿过的情况。Because there is a certain gap between the filter screen and the oil collecting part, the filter screen is controlled by the motor to rotate, and the oil fume is filtered through the filter screen as much as possible. Therefore, the drainage channel guides the oil smoke to gather in the center of the filter screen, reducing the situation that the oil smoke passes through the gap between the filter screen and the oil collecting part without being filtered.
4.本公开提供的导油环,所述引风翻边与所述集油部一体连接,且所述引风翻边与所述集油部相连处由圆角过渡。4. In the oil guide ring provided by the present disclosure, the draft flanging is integrally connected with the oil collecting part, and the connecting part of the draft flanging and the oil collecting part is transitioned by rounded corners.
油烟机工作时引导外部气流进入油烟机内部,首先经过导油环,本方案中带有油烟的气流通过导油环上引风翻边构成的引流通道进入油烟机内部。由于气流高度通过导油环,因此气流与导油环接触时发生撞击,本方案中通过圆角过度的引风翻边和集油部,减小空气撞击的阻力,并引导空气聚集进入引流通道。减小了油烟机工作时产生的噪音。When the range hood is working, it guides the external airflow into the range hood, and first passes through the oil guide ring. In this solution, the airflow with oil smoke enters the range hood through the drainage channel formed by the wind guide flange on the oil guide ring. Since the airflow passes through the oil guide ring at a high level, the airflow collides with the oil guide ring. In this solution, excessive rounded corners are used to reduce the resistance of air impact and guide the air to gather into the drainage channel. . Reduce the noise generated when the range hood is working.
5.本公开提供的导油环,所述挡油部的至少一部分凸出设置并形成收集槽。5. In the oil guide ring provided by the present disclosure, at least a part of the oil retaining portion is protrudingly provided and forms a collecting groove.
油渍从滤网上被甩出后,受到环形的挡油部的阻碍,但是由于集油部为环形,因此油液依靠自身的动能和势能沿集油部表面向引油槽流动。但是单个油液的体积小,在贴合流动过程中因摩擦而不断损失,针对体积较小的油液来说,挡油部上的移动路径较长,因此单一的油液不易被引油槽收集。本方案中,由于挡油部凸出设置,因此油液在被挡油部捕获时,挡油部凸出形成斜面或弧面,由于油液自身依然具有一定动能,油液向挡油部凸出的位置汇聚,从而使油液的体积汇聚增大,并沿挡油部凸出的部位向引油槽内流动。After the oil stains are thrown out from the filter screen, they are hindered by the annular oil retaining part. However, because the oil collecting part is annular, the oil relies on its own kinetic energy and potential energy to flow along the surface of the oil collecting part to the oil guide groove. However, the volume of a single oil is small, and it is constantly lost due to friction during the process of fitting and flowing. For the smaller oil, the moving path on the oil retaining part is longer, so a single oil is not easy to be collected by the oil tank . In this solution, because the oil baffle is arranged protruding, when the oil is captured by the oil baffle, the oil baffle protrudes to form a slope or arc. Since the oil itself still has a certain kinetic energy, the oil protrudes toward the oil baffle. Converges at the exiting position, so that the volume of the oil converges and increases, and flows into the oil guide groove along the protruding part of the oil baffle.
6.本公开提供的导油环,所述收集槽的倾斜度沿靠近所述引油槽的方向逐渐增大。6. In the oil guide ring provided by the present disclosure, the inclination of the collecting groove gradually increases in the direction close to the oil guide groove.
油液的流动方向为向引油槽方向流动,由于收集槽为环形,因此环形在靠近引油槽的部位倾斜度逐渐变缓。本方案中使收集槽沿靠近引油槽方向的倾斜度增大,使油液不易在倾斜度相对平缓的部位停留,提高油液的收集效率。The flow direction of the oil is toward the oil guide groove. Since the collecting groove is annular, the inclination of the ring near the oil guide groove gradually becomes slower. In this solution, the inclination of the collection tank in the direction close to the oil introduction tank is increased, so that the oil is not easy to stay at the relatively flat slope, and the collection efficiency of the oil is improved.
7.本公开提供的导油环,还包括:导油件,设于所述引油槽上并向所述连接部外侧方向延伸。7. The oil guide ring provided by the present disclosure further includes: an oil guide member, which is arranged on the oil guide groove and extends toward the outer side of the connecting portion.

The oil collecting part 1 is ring-shaped, and the oil fume flows and converges along the inner surface of the oil collecting part 1, and finally flows out through the oil guiding groove 11 in a concentrated manner. The annular oil collecting part 1 has a certain width, so it forms a shape with two ends open, and one end of the opening is provided with a connecting part 2 for connecting with a range hood.
对于导油环的结构不做具体限制,本实施例中,如图1、图2、图3所示,还包括:引风翻边3,所述引风翻边3设于所述集油部1远离所述引油槽11的 一端,所述引风翻边3向所述引油槽11方向延伸并形成引导油烟的引流通道。集油部1上两端开口,引油槽11靠近连接部2的一端设置,另一端延伸出引风翻边3,引风翻边3向集油部1包围的范围内弯折,并形成一个引导油烟进入集油部1范围的引流通道。油烟通过引流通道穿过集油部1进入油烟机。作为可替换的实施方式,集油部1远离连接部2的一端为止口。There are no specific restrictions on the structure of the oil guide ring. In this embodiment, as shown in Figure 1, Figure 2, and Figure 3, it also includes: an induced air flanging 3, which is provided in the oil collecting The portion 1 is far away from one end of the oil guiding groove 11, and the air guiding flange 3 extends in the direction of the oil guiding groove 11 and forms a drainage channel for guiding oil fume. The two ends of the oil collecting part 1 are open, the oil guiding groove 11 is set close to one end of the connecting part 2, and the other end extends out of the air guiding flanging 3, which bends in the range enclosed by the oil collecting part 1, and forms a The oil fume is guided into the drainage channel within the scope of the oil collecting part 1. The oil fume enters the range hood through the oil collecting part 1 through the drainage channel. As an alternative embodiment, one end of the oil collecting portion 1 away from the connecting portion 2 is closed.
对于引流通道的形状不做具体限制,本实施例中,如图1、图3、图4所示,所述引流通道的轴向截面面积沿靠近所述连接部2的方向逐渐变小。由于滤网7与集油部1之间留有一定间隙,滤网7受控于电机转动,油烟尽可能的通过滤网7进行过滤。因此引流通道引导油烟向滤网7中心方向聚拢,减少油烟未经过滤而从滤网7和集油部1之间的间隙穿过的情况。作为可替换的实施方式,引流通道的内径沿油烟进入的方向不变。作为另一种可替换的实施方式,引流通道的内径沿油烟进入的方向逐渐变大。There is no specific restriction on the shape of the drainage channel. In this embodiment, as shown in FIGS. 1, 3 and 4, the axial cross-sectional area of the drainage channel gradually decreases in the direction close to the connecting portion 2. Since there is a certain gap between the filter screen 7 and the oil collecting part 1, the filter screen 7 is controlled by the motor to rotate, and the oil fume is filtered through the filter screen 7 as much as possible. Therefore, the drainage channel guides the oil fume to gather in the center direction of the filter screen 7, reducing the situation that the oil fume passes through the gap between the filter screen 7 and the oil collecting part 1 without being filtered. As an alternative embodiment, the inner diameter of the drainage channel does not change along the direction in which the oil fume enters. As another alternative embodiment, the inner diameter of the drainage channel gradually becomes larger along the direction in which the oil fume enters.
对于引风翻边3与集油部1的连接方式不做具体限制,本实施例中,如图3、图4所示,所述引风翻边3与所述集油部1一体连接,且所述引风翻边3与所述集油部1相连处由圆角过渡。油烟机工作时引导外部气流进入油烟机内部,首先经过导油环,本方案中带有油烟的气流通过导油环上引风翻边3构成的引流通道进入油烟机内部。由于气流高度通过导油环,因此气流与导油环接触时发生撞击,本方案中通过圆角过度的引风翻边3和集油部1,减小空气撞击的阻力,并引导空气聚集进入引流通道。减小了油烟机工作时产生的噪音。作为可替换的实施方式,引风翻边3焊接在集油部1上。作为另一种可替换的实施方式,引风翻边3通过螺栓固定在集油部1上。There is no specific restriction on the connection mode of the induced air flanging 3 and the oil collecting part 1. In this embodiment, as shown in Figs. 3 and 4, the induced air flanging 3 is integrally connected with the oil collecting part 1. In addition, a rounded corner transitions at the connection between the induced draft flange 3 and the oil collecting portion 1. When the range hood works, it guides the external airflow into the range hood, and first passes through the oil guide ring. In this solution, the airflow with oil smoke enters the inside of the range hood through the drainage channel formed by the wind guide flange 3 on the oil guide ring. Since the airflow passes through the oil guide ring at a high level, the airflow collides when it comes into contact with the oil guide ring. In this solution, the excessive rounded corners of the draft flange 3 and the oil collecting part 1 are used to reduce the resistance of air impact and guide the air to gather Drainage channel. Reduce the noise generated when the range hood is working. As an alternative embodiment, the draft flange 3 is welded to the oil collecting part 1. As another alternative embodiment, the draft flange 3 is fixed on the oil collecting part 1 by bolts.
对于挡油部的形状不做具体限制,本实施例中,如图3、图4所示,所述挡油部的至少一部分凸出设置并形成收集槽。油渍从滤网7上被甩出后,受到环形的挡油部的阻碍,但是由于集油部1为环形,因此油液依靠自身的动能和势能沿集油部1表面向引油槽11流动。但是单个油液的体积小,在贴合流动过 程中因摩擦而不断损失,针对体积较小的油液来说,挡油部上的移动路径较长,因此单一的油液不易被引油槽11收集。本方案中,由于挡油部凸出设置,因此油液在被挡油部捕获时,挡油部凸出形成斜面或弧面,由于油液自身依然具有一定动能,油液向挡油部凸出的位置汇聚,从而使油液的体积汇聚增大,并沿挡油部凸出的部位向引油槽11内流动。作为可替换的实施方式,挡油部朝向滤网7的内表面为平面。There is no specific restriction on the shape of the oil blocking portion. In this embodiment, as shown in Figs. 3 and 4, at least a part of the oil blocking portion is protruding and forms a collecting groove. After the oil stains are thrown from the filter screen 7, they are hindered by the annular oil retaining part. However, because the oil collecting part 1 is annular, the oil flows along the surface of the oil collecting part 1 to the oil guiding groove 11 by its own kinetic energy and potential energy. However, the volume of a single oil is small, and it is constantly lost due to friction during the process of fitting and flowing. For the smaller oil, the moving path on the oil retaining part is longer, so a single oil is not easy to be led into the oil groove 11 collect. In this solution, because the oil baffle is arranged protruding, when the oil is captured by the oil baffle, the oil baffle protrudes to form a slope or arc. Since the oil itself still has a certain kinetic energy, the oil protrudes toward the oil baffle. Convergence at the exiting position, so that the volume of the oil converges and increases, and flows into the oil guide groove 11 along the protruding part of the oil baffle. As an alternative embodiment, the inner surface of the oil retaining portion facing the filter screen 7 is flat.

In this embodiment, as shown in FIG. 1, the inclination of the collecting groove gradually increases in the direction close to the oil guiding groove 11. The flow direction of the oil is toward the oil guide groove 11, and since the collecting groove is annular, the inclination of the ring near the oil guide groove 11 gradually decreases. In this solution, the inclination of the collecting trough in the direction close to the oil guiding trough 11 is increased, so that the oil is not easy to stay at the position with a relatively gentle slope, and the oil collection efficiency is improved. In this embodiment, the specific shape of the increased inclination is that the lower half of the collecting groove, the corresponding arc radius, gradually increases in the direction close to the oil guide groove 11. As an alternative embodiment, the lower half of the collection tank is a broken line structure formed by successively connecting multiple line segments. The inclination angles between different line segments are different, and the inclination angle between each line segment gradually increases in the direction close to the oil guide groove 11. Big.
