Description
【技术领域】【Technical field】
本发明涉及抽油烟机领域。The invention relates to the field of range hoods.
【背景技术】【Background technique】
目前，已有设置有可封闭的进风口的抽油烟机出现。该种抽油烟机的进风口处于开启状态时，该进风口供油烟流过进而流入该种抽油烟机。该种抽油烟机的进风口处于被封闭状态时，油烟则不能流入该种抽油烟机。事实上，现有的设置有可封闭的进风口的抽油烟机，其进风口的开启及封闭方式较为单一，缺乏改进。At present, existing range hoods that are provided with closable air inlets appear. When the air inlet of the range hood is in an open state, the air inlet allows oil smoke to flow through and then flow into the range hood. When the air inlet of the range hood is in a closed state, oil fumes cannot flow into the range hood. In fact, the existing range hoods provided with closable air inlets have a single way of opening and closing the air inlets, which lacks improvement.
除非有充足的证据支持，否则这里所述的现有技术并不意味着承认这些现有技术在本申请的申请日之前为本发明所涉及领域的普通技术人员公知。References to prior art herein are not intended to be an admission that such prior art was known to those of ordinary skill in the art to which the present invention pertains prior to the filing date of this application, unless supported by sufficient evidence.

为使本发明的目的、方案以及有益效果更加清楚明了，下面结合附图和优选实施例对本发明作进一步说明。个别附图可能不够精准，此种情况下，请以文字描述为准。In order to make the object, scheme and beneficial effect of the present invention more clear, the present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments. Individual drawings may not be accurate enough, in this case, please refer to the text description.
实施例1Example 1
本发明提出的一种抽油烟机实施例，为侧吸式抽油烟机，其包括机壳1、风机2、板体件3、限位装置和可封闭的进风口4。风机2设置于机壳1内。板体件3被设置为可在封闭位置与开启位置之间切换，板体件3处于封闭位置时其封闭进风口4，板体件3处于开启位置时进风口4开启。可见，板体件3用于控制进风口4的开闭。An embodiment of a range hood proposed by the present invention is a side suction range hood, which includes a casing 1 , a fan 2 , a plate body 3 , a limiting device and a sealable air inlet 4 . The fan 2 is arranged in the casing 1 . The plate body part 3 is configured to be switchable between a closed position and an open position. When the plate body part 3 is in the closed position, it closes the air inlet 4, and when the plate body part 3 is in the open position, the air inlet 4 is opened. It can be seen that the plate body part 3 is used to control the opening and closing of the air inlet 4 .
板体件3，被设置为可在风机2产生的气流的作用下绕其转轴5转动从而自封闭位置切换至开启位置，且在气流的作用消失时板体件3可在自身重力的作用下复位(即，在自身重力的作用下绕其转轴5转动从而自开启位置切换至封闭位置)。该抽油烟机实施例的限位装置，用于限定板体件3绕转轴5转动的极限位置。具体地，板体件3绕转轴5转动的极限位置有两个，一个为如图1所示的封闭位置，另一个为如图2所示的开启位置。The plate body part 3 is arranged to be able to rotate around its rotating shaft 5 under the action of the airflow generated by the fan 2 so as to switch from the closed position to the open position, and when the effect of the airflow disappears, the plate body part 3 can be under the action of its own gravity Reset (that is, rotate around its rotating shaft 5 under the action of its own gravity to switch from the open position to the closed position). The limiting device of this embodiment of the range hood is used to limit the limit position of the rotation of the plate body part 3 around the rotating shaft 5 . Specifically, there are two limit positions for the plate body 3 to rotate around the rotating shaft 5 , one is the closed position as shown in FIG. 1 , and the other is the open position as shown in FIG. 2 .
板体件3的数量为两个。两个板体件3均呈片状结构，两个板体件3的工作原理相同。各板体件3均包括连接在一起的一体成型的第一板体6和第二板体7，转轴5设置于第一板体6与第二板体7的连接处，第一板体6位于对应的第二板体7的上方。第二板体7用作对应的第一板体6的配重。每个板体件3均对应设置有一个转轴5，该转轴5贯穿所对应的板体件3。各板体件3的重心均临近其转轴5。The number of plate body parts 3 is two. The two board parts 3 both have a sheet structure, and the working principles of the two board parts 3 are the same. Each plate body part 3 all comprises the integrally formed first plate body 6 and the second plate body 7 that are connected together, and the rotating shaft 5 is arranged on the junction of the first plate body 6 and the second plate body 7, and the first plate body 6 It is located above the corresponding second plate body 7 . The second plate body 7 is used as the counterweight of the corresponding first plate body 6 . Each plate part 3 is correspondingly provided with a rotating shaft 5 , and the rotating shaft 5 passes through the corresponding plate part 3 . The center of gravity of each plate body part 3 is close to its rotating shaft 5 .
两个板体件3均处于封闭位置时，该两个板体均倾斜设置，如图1所示。此时，若风机2运行，两个板体件3的内侧产生负压，因而形成如图2中的箭头所示的气流，在该气流的推动力的作用下，两个板体件3的第一板体6均绕转轴5朝向抽油烟机的内部转动(同时，两个板体件3的第二板体7均绕转轴5朝向抽油烟机的外部转动)，直至第一板体6绕转轴5朝向抽油烟机的内部转动到达极限位置，此时两个板体件3均处于开启位置，如图2所示，此时两个板体件3与水平面的夹角均为a＜90°，如图2所示。若风机2停止运行，则两个板体件3均在自身重力的作用下绕其转轴5转动从而自开启位置切换至封闭位置，具体地，两个板体件3的第一板体6均绕转轴5朝向抽油烟机的外部转动(同时，两个板体件3的第二板体7均绕转轴5朝向抽油烟机的内部转动)，直至切换至如图1所示的封闭位置，此时，两个板体件3与水平面的夹角相同，均为锐角，且小于a。When the two plate parts 3 are in the closed position, the two plate bodies are arranged obliquely, as shown in FIG. 1 . At this moment, if the blower fan 2 operates, the inner sides of the two plate parts 3 will generate negative pressure, thereby forming the airflow shown by the arrow in Figure 2. Under the action of the driving force of the airflow, the two plate parts 3 will The first plates 6 all rotate around the rotating shaft 5 towards the inside of the range hood (at the same time, the second plates 7 of the two plate parts 3 all rotate around the rotating shaft 5 towards the outside of the range hood), until the first plate 6 Rotate around the rotating shaft 5 toward the inside of the range hood to reach the limit position. At this time, the two plate parts 3 are in the open position, as shown in Figure 2. At this time, the angles between the two plate parts 3 and the horizontal plane are a< 90°, as shown in Figure 2. If the blower fan 2 stops running, the two plate parts 3 all rotate around their rotating shafts 5 under the action of their own gravity so as to switch from the open position to the closed position. Specifically, the first plates 6 of the two plate parts 3 are Rotate around the rotating shaft 5 toward the outside of the range hood (at the same time, the second plates 7 of the two plate parts 3 rotate toward the inside of the range hood around the rotating shaft 5), until switched to the closed position as shown in Figure 1, At this time, the included angles between the two plate parts 3 and the horizontal plane are the same, both are acute angles, and are smaller than a.
以上仅是本发明的优选实施例，对某些技术特征进行增加、删减、修改或替换还可以得到其他的实施例。如，也可以是，抽油烟机还包括锁定装置，被设置为可将板体件锁定在开启位置。锁定装置将板体件锁定在开启位置时，若风机停止运行，板体件也保持在开启位置，只有解除锁定装置对板体件的锁定，板体件方可在自身重力的作用下复位，自开启位置切换至封闭位置。再如，也可以是，每个板体件均对应设置有两个转轴，该两个转轴设置于所对应的板体件的两端，且该两个转轴在延伸方向上相重合。事实上，转轴的结构还有其它的可能，只要其能够实现供板体件绕其转动的功能即可。再如，也可以是，板体件在风机产生的气流的作用下绕其转轴转动从而自封闭位置切换至开启位置时，板体件的第一板体朝向抽油烟机的外部转动(同时，板体件的第二板体朝向抽油烟机的内部转动)。再如，也可以是，板体件的数量为一个、三个、四个或更多。The above are only preferred embodiments of the present invention, and some technical features can be added, deleted, modified or replaced to obtain other embodiments. For example, it is also possible that the range hood further includes a locking device configured to lock the plate body in the open position. When the locking device locks the board body in the open position, if the fan stops running, the board body remains in the open position. Only when the locking device locks the board body is released, the board body can be reset under the action of its own gravity. Switch from open position to closed position. For another example, it is also possible that each board member is correspondingly provided with two rotating shafts, the two rotating shafts are arranged at both ends of the corresponding board member, and the two rotating shafts overlap in the extending direction. In fact, there are other possibilities for the structure of the rotating shaft, as long as it can realize the function of allowing the plate body to rotate around it. For another example, it may also be that when the plate body rotates around its rotating shaft under the action of the airflow generated by the fan to switch from the closed position to the open position, the first plate of the plate body rotates toward the outside of the range hood (at the same time, The second plate of the plate body rotates toward the inside of the range hood). For another example, it is also possible that the number of plate body parts is one, three, four or more.
