Abstract

本实用新型公开一种烟道装置,旨在提供一种既能防止他家油烟通过公共烟道串入,又能方便拆装清洗的装置。其外框安装在烟道口内,内框通过罗纹安装在外框内,阀板以铰链与内框连接,内框上有限位板限制阀板的开启,阀板以重力自动关闭。内框可通过罗纹拆装,以便于清洗。

Description

烟道装置
技术领域
本实用新型涉及一种油烟排入公用烟道的装置。
背景技术
现有的经油烟机排入烟道的装置,不能有效阻止他家的油烟经烟道串入,固定在烟道口,油烟日久堆积,难于清洗。
实用新型内容
本实用新型克服了现有技术的上述不足,提供一种既能阻止他家油烟经烟道串入,又能方便地拆下清洗的装置。
本实用新型采用如下技术方案:一种烟道装置,由外框,内框,阀板,限位板,铰链组成。
外框的一端固定在烟道口,另一端的外圈连接油烟机,其内圈有内罗纹,内框上的罗纹与之配合,内框伸入烟道的一端有铰链,连接有阀板,阀板关闭时在垂直方向小于90度,在开启时有限位板限位,使最大开启位阀板不超过垂直位,以便阀板在重力作用下复位。
需清洗时,可拧开罗纹,拆下内框进行清洗,确保阀板灵活开合。
本实用新型的有益效果是:有效阻断油烟串味,清洗方便。
附图说明
附图是本实用新型的示意图;
具体实施方式
下面结合附图对本实用新型作进一步描述:
附图是本实用新型的一个实施例,首先将外框1的方口插入烟道口,并密封固定,内框2与外框1以罗纹连接,内框2一端伸入烟道,内框2端口上短下长,呈倾斜平面,下边装有铰链5和限位板4,阀板3通过铰链5与内框2连接,油烟机不工作时,阀板3在重力作用下关闭;阀板3开启时,受限位板4限制,阀板3在垂直方向不超过90度,以便阀板3靠重力复位。需清洗时,只要拧开罗纹,拆下内框2,就能方便地清洗阀板3和内框2。将油烟机排烟管与外框1外圈连接,即可有效工作。
