[建议]请大家注意卫生间的0区1区2区问题

han2003

<P>新民规对于卫生间分区的规定改变了，但是规定写得很有问题，产生了很多疑义。比如对于无盆淋浴来说，规范的图没有画出2区的范围，说明却写出了2区的定义方法。假如真的考虑这个2区的话，竟然要半径1.8m的2.25m以下区域无法安装插座，这对于普通住宅来讲实在是很困难了。带着问题查看了iec规范原文，发现iec规范其实说明的已经很清楚了：以下引自IEC 60364-7-701-2006</P>
<P>701.30.3 Description of zone 1<BR>Zone 1 is limited<BR>a) by the finished floor level and the horizontal plane corresponding to the highest fixed<BR>shower head or water outlet or the horizontal plane lying 225 cm above the finished floor<BR>level, whichever is higher,<BR>NOTE 1 In Belgium, Denmark, Hungary and Italy, if the bottom of the bath tub or shower basin is located<BR>higher than 15 cm from the floor level, the horizontal plane is located 225 cm above the bottom of bath tub or<BR>shower basin.<BR>NOTE 2 In the Netherlands 225 cm is replaced by 260 cm.<BR>NOTE 3 In the Czech Republic and in Spain the zone 2 is considered above the zone 1 as far as the ceiling or<BR>the horizontal plane lying 300 cm above the finished floor level, whichever is higher.<BR>b) by the vertical surface:<BR>– circumscribing the bath tub or shower basin (see Figure 701.1),<BR>– at a distance of 120 cm from the centre point of the fixed water outlet on the wall or<BR>ceiling for showers without basin (see Figure 701.2 ).<BR>Zone 1 does not include zone 0.<BR>The space under the bath tub or shower is considered to be zone 1.<BR>NOTE 4 In Spain, and for showers without basin, where the water outlet is fixed the vertical limit is fixed at 60 cm<BR>around the water outlet.<BR>NOTE 5 In Spain, the space under the bath tub or shower basin accessible without the use of a tool is considered<BR>to be zone 1. If it is accessible only with the use of a tool, it is considered to be neither zone 0, nor 1 nor 2.</P>
<P>701.30.4 Description of zone 2<BR>Zone 2 is limited<BR>a) by the finished floor level and the <FONT color=#ff0033>horizontal plane corresponding to the highest fixed<BR>shower head or water outlet</FONT> or the horizontal plane lying 225 cm above the finished floor<BR>level, whichever is higher,<BR>NOTE 1 In the Netherlands, 225 cm is replaced by 260 cm.<BR>b) by the vertical surface at the boundary of zone 1 and the parallel vertical surface at a<BR>distance of 60 cm from the zone 1 border ( see Figure 701.1).<BR><FONT color=#ff0033>For showers without basin, there is no zone 2</FONT> but an increased zone 1 is provided by the<BR>horizontal dimension of <FONT color=#ff0033>120 cm</FONT> mentioned in the second dash of 701.30.3 b) (see Figure<BR>701.2).<BR>NOTE 2 In Spain, zone 2 exists in any case.</P>

顺便说一下，规范取消了过去的3区。目前新的建筑物电气装置 第7部分：特殊装置或场所的要求 第701节：装有浴盆或琳浴盆的场所 应该还尚未出版，大家画图时我建议可以先按IEC的上述条文执行。卫生间的洗衣机插座或者开关，只需要距离喷头1.2m外就可以了。另外说一下，规范提到的2.25m应该是距建筑物完成面的高度，鉴于今后仍有住户自行改造或者施工误差的因素，如有需要，大家标注高度时最好稍微提高一些，比如写2.3m或者2.4m，不要卡在2.25m上。

深刻！关于新民规卫生间分区重新修订的内容，依然不够严密。不知道全国的审图员有没有去研究IEC 60364-7-701-2006的相关内容。

强烈建议规范编制组对此问题做出补充说明，以免引起设计混乱

<P>民规里面自相矛盾的很多，</P>
<P>2区装设插座是有限制的，比如IP54，加30mA漏电保护或SELV供电。</P>
<P>照明开关往往装在门外，不存在这个问题，热水器插座可以装到2.3m，这之前也是这样设计的。</P>
<P>住宅设计中“<STRONG><FONT color=#000080>3.4.2</FONT></STRONG>  无前室的卫生间的门不应直接开向起居室（厅）或厨房。”</P>
<P>建筑专业往往都设了前室，至于剃须插座、一般都设在这里。</P>
<P>至于设置洗衣机插座，那卫生间面积很大才行。(删除部分内容，以免误导)</P>
<P>另外，个人认为防溅型、防水灯、防水防潮灯、防尘灯、尘密灯，虽然对应了各自的IP等级，但这些说法不够严谨，</P>
<P>没研究过的，根本不清楚其具体的防护含义，还是以IPXX说清楚比较好。</P><BR><BR>

IEC中，无盆淋浴已经没2区的概念了

wosuwoxing

<P>翻了一下民规实施指南，</P>
<P>0区——只允许安装装用于浴盆的电器；</P>
<P>1区——只可装设水加热器</P>
<P>2区——只可装设水加热器和II类灯具；</P>
<P>.............</P>

HAN2003真是一个细心人

<P>哈哈哈，顶出去。</P>
<P>要是IEC的英文能翻译成中文就更好了。。。</P>
