取暖器进风口大小

请各位大侠帮忙看看

附图是取暖器的进风口,红色是发热体

现进风口宽度是9mm, 听说2012标准要求实验指是8.6mm,

那么这个开口不合格吗?

大于8.6的话,要距离足够才可以,所以还是建议最好小于8.6;

谢谢马蹄,不知道这8.6mm是不是出自EN 60335-1 的8.1.11(2012版)这是客户跟我说的,不过我看不到呢?

另外2-30 的2012版有个22.z101这条会不会有影响呢,谢谢!

测试指模拟小孩手指部分长度57.9带关节,直径8.6,前端SR4.3;
标准60335-1   2012   8.1.1   8.220.2

2-30的22.101 主要是41#测试棒,比这个大很多,不会有影响;

EN标准的22.Z101是有影响的,一般不能超过5.5mm,除非满足下面提供的a)-c)的条件的其中一条:
22.Z101
Stationary appliances part or all of the body of which are positioned at a height below 850 mm from the floor and portable appliances that can be used on the floor shall not have accessible openings with a minor dimension exceeding 5,5 mm.
This requirement does not apply to:
a) openings that have a bigger dimension where live parts or moving parts are positioned beyond an arc of 30 mm centred on a perpendicular point 14 mm behind the face of the opening;
b) openings below 100 mm from the floor if they are not directly visible in normal use unless the
appliance generates glow or a continuous noise to attract attention;
c) on the rear/back surface that is parallel to the wall of appliances which, according to the instructions,
shall be placed against a wall or have a wall clearance of less than 30 mm when wall-mounted.

出风口的宽度最好不要开那么大,另外这里还要考虑冲击后能否接触发热体。
