what you thought was 为了清扫方便. that i think is unnessasary. the cleaners have to clean the 马桶sit, so basicly it would be easier to go in the stall and clean. 用较少的柱子来支撑, well, some people like to kick things so 柱子 propably won't be such a good choice because it might bend or change shape over time. Using a special type of metal might not change shape, but that is too expensive.
prevent loosing up, by that i meant people slam the door very hard and that could cause 螺丝 to loose up.
i don't know much on this question. the answer, better described as guess, was made by the look of the pipe in the pictures you had, so i have no idea how to answer "special-made pipes是什么" or "水流如何产生".www.ddhw.com
those questions are not so hard if you been in 美国 for a while.
1) 为什么有许多公共卫生间之间的隔板往往是从上面吊下,而悬空?为什么不是用地面来支撑? you want to see if anyone is in there because some times people just forget to lock the door. this way you can see the feet.www.ddhw.com
2) 公共卫生间门上的一些螺丝。这些“一”字形的螺丝与我们常见到的不同,这些螺丝只能拧紧,不能拧松。也就是说,只能用螺丝刀顺时针旋转,不能逆时针。请问,为什么要这么设计?(尽管一些公共卫生间螺丝不是这样,但是我在美国见多有许多卫生间都是这样) what i think is that they design it like that is to prevent the door from loosening up. imagine that you sit there and the door goes open by itself because the 螺丝 fell loose.www.ddhw.com
3) 1。无水缸马桶的工作原理是什么?为什么没有水缸也可以使用? 2。无水缸马桶能解决漏水问题吗?(也就是说至少保证3,5年不漏水吗?) 3。无水缸马桶很好用,冲刷一次可以立即冲刷第二次而不需要象有水缸马桶那样需要一段时间的等待。那么为什么在个人家庭里很少见?为什么没有推广? 1. those kind of 马桶 has a pipe that connect to the wall which connect to the water dirctly. when you 冲刷, the water comes out of the pipe instead of the 水缸. 2. i don't really know this but i think that it can. 3. this is because of the pipe. not so many private buildings have those special-made pipes.
