Parts such as the door 6 in the toilet, air outlet 7, observation window 8, water pipe 9 all adopt modularized design, after making according to certain specification in advance, are mounted on the body of wall 1 according to certain mounting structure.
Accompanying drawing 4 is the structural representation that is provided with the door 6 of observation window 8 with accompanying drawing 5.Wherein, the detailed mounting structure between door 6 and the body of wall 1 is shown in accompanying drawing 6.This door 6 is made up of doorframe 10 and door leaf 20, is hinged through hinge 14 between doorframe 10 and the door leaf 20, and door leaf 20 can be opened and closed.Except a pair of door knob 24 that is positioned at the indoor and outdoor both sides, it is smooth that remaining surface keeps, to reduce the laying dust point as far as possible on the door leaf 20.
Implement double-layer seal between doorframe 10 and the door leaf 20.The ground floor sealing utilizes the sealing ring 15 that is clipped between the two to realize.One side of sealing circle 15 is fixed on the door leaf 20, continuously around 20 1 weeks of door leaf.When door was closed, the opposite side of sealing ring 15 was fitted with doorframe 10 mutually continuously, does not stay the gap.
The implementation of second layer sealing is following: on the indoor surface of facing of doorframe 10, be fixed with decorative panel 40, this decorative panel 40 is the complete covering of inner surface of doorframe 10, and covered the part of color steel 5 and door leaf 20 simultaneously.On the surface that faces doorframe 10 of decorative panel 40, be fixed with a pair of sealing gasket 41.This a pair of sealing gasket 41 is all around whole 10 1 weeks of doorframe, and its opposite side surface fits with the door leaf 20 of color steel 5 when closing respectively mutually continuously, do not stay the gap.Decorative panel 40 is fixed on the doorframe 10 through stainless steel self tapping screw 42; This screw 42 is a flat head screw; Its tack face is lower than the surface of decorative panel 40 after installing; In this depression, attach a stainless cosmetic sheet 43, make the surfacing of whole decorative panel 40 not have depression, better realize cleaning function.Simultaneously, the junction between decorative panel 40 and color steel 5 applies a small amount of silica gel, realizes better sealing.
Adopt door leaf 20 behind the double-layer seal, doorframe 10, sidewall 3 threes to face indoor surface in the same plane basically, make and satisfy the requirement of toilet by not laying dust of whole surfacing.
Function of shielding between doorframe 10 and the door leaf 20 has adopted double layer screen to realize equally.
Conduction between the side wall surface of the ground floor shielding side wall surface through door leaf 20 and doorframe 10 contacts and realizes.On the sidewall inwardly of doorframe 10, intactly pasted a circle copper coin 13, this copper coin 13 does not have seam welding mutually with secondary shielding body 11, thereby conduct electricity to contact without interruption mutually with secondary shielding body 11.On the sidewall of door leaf 20, intactly being fixed with the arciform metal spring sheet 22 of a circle, arches upward up in the top of this spring leaf 22, and with the surperficial seamless applying mutually of copper coin 13.On the other hand, spring leaf 22 is depressed when contacting with doorframe 10 slightly, has played simultaneously tightening the effect of door leaf 20 at closing time, guarantees that door leaf 20 can be embedded in the doorframe 10 securely, makes the sealing reliability of door promote to some extent.
The implementation of second layer shielding is comparatively complicated.In the outdoor side of facing of doorframe 10, indent offer slot 16, this slot 16 is offered around whole doorframe 10 continuously, is that the elastic sheet metal 17 by a pair of ring-type constitutes.Face an indoor side at door leaf 20, protrusion is provided with the metal insert 25 of a ring-type, and this inserted sheet 25 is around whole door leaf.When door was closed, inserted sheet 25 inserted in the slot 16s, and the both side surface of inserted sheet 25 contacts with the slot 16 inwall respectively mutually without interruption, made the contact of continuous conduction mutually between secondary shielding body 11 and the 3rd shield 21.Sheet metal 17 must be processed with the good metal of elasticity, could guarantee door like this after opening and closing repeatedly, and slot 16 still has better elastic, makes door the slit that can't contact after closure, can not occur.
In traditional double layer screen toilet, must cooperate shielding body of wall and clean wall, Yishanmen respectively is installed on two-layer body of wall, accomplish shielding and clean effect respectively.The method complex structure makes airtight reliability decrease, and cost is also higher.And the individual layer door through being designed in the present embodiment just can be realized sealing efficiently and shielding simultaneously.When door was closed, door leaf 20, doorframe 10, shield shell 1 three seamlessly connected into as a whole, had both satisfied the requirement that the screened room needs are processed a closure casing with conductor, and the nothing that has also satisfied the toilet is leaked clean requirement.And this sealing and shielding construction are dual fail-safe, and connection reliability is quite high.
Accompanying drawing 7 is for being opened in the mounting structure sketch map of the observation window 8 on the door 6.Observation window 8 is made up of window frame of metal 60, lucite luffer boards 50, and window frame 60 is embedded in the door leaf 20.Window frame 60 is the metal frame of an annular, and its external boundary and door leaf 20 adopt the full weld welding, thereby guarantee the complete free of discontinuities of connection between the two.
At first, adopt wire netting 52 to accomplish the function of shielding of luffer boards 50.Wire netting 52 closely is attached to the inner surface of luffer boards 50, luffer boards 50 are intactly covered, and its whole circle edge all turns over to the outer surface of luffer boards 50, thereby the whole circle edge of luffer boards 50 is all wrapped.Between the surfaces externally and internally of the edge of wire netting 52 and luffer boards 50, all sandwich double faced adhesive tape, play temporary fixed effect.
In order further to avoid electromagnetic exposure, on the ring-type contact-making surface between cutting ferrule 61 and the installed surface 65, also accompany one deck and wire netting 52 identical wire netting pads, thereby realize the shielding dual fail-safe of 60 of cutting ferrule 61 and window frames.The wire netting 52 that is adopted in the said structure is the special-purpose copper mesh of electromagnetic shielding, and is different according to the requirement of shielding grade, can select different nets.Under the prerequisite that does not influence shield effectiveness, can select the transparency high net of trying one's best.
Hermetically-sealed construction between luffer boards 50 and window frame 60 and the door leaf 20 is realized through a decoration panel 70.This panel 70 is a ring-type, and intactly covers on the outer surface of seam between luffer boards 50 and the door leaf 20.Interior boundary connects with luffer boards 50 mutually hermetically, and external boundary connects with door leaf 20 mutually hermetically.The outer surface of inner and outer boundary is smooth inclined-plane, thereby reduces dust-collecting point.Panel 70 and luffer boards 50 and and door leaf 20 between seam crossing, all scribble sealing silica gel 72.
The inner boundary of panel 70 and external boundary have formed first installed surface of facing mutually with the outer surface of luffer boards 50 75 and second installed surface of facing mutually with the outer surface of door leaf 20 76 respectively all towards panel 70 inboard bendings.Between the outer surface of first installed surface 75 and luffer boards 50, accompany the sealing gasket 41 of a loop, thereby realize sealing.Second installed surface 76 fits tightly with the outer surface of door leaf 20 mutually, and from the outer surface of panel 70, directly penetrates screw 73, and this screw 73 passes second installed surface 75, door leaf 20 and window frame 60, and the three is fixedly connected.Screw 73 is after passing panel 70; Therefore its upper surface can need to paste a fritter cosmetic sheet 74 at the upper surface of screw 73 a little less than the outer surface of panel 70, makes the smooth nothing depression of outer surface of whole front panel 70; Avoid control of dust, and play the effect of avoiding occurring leakage point.
Existing various shielding windows generally are only to design its structure from the angle that shields, and are difficult to directly use in the toilet.Therefore if in toilet of the present invention, directly adopt commercially available shielding windows, also must pass through repacking.Such as setting up decoration panel 70 and sealing gasket 41 realizing sealing, and the inner surface of luffer boards 50 is adjusted to the inner surface of shield shell on every side as far as possible and flushes.
The ventilating system of toilet is its very important part.On the body of wall 1 of toilet, be provided with a plurality of air outlet pipelines and exhaust outlet pipeline.In simple terms, when all kinds of airducts pass shield shell, must be through the transition of below-cutoff wave guide window 35, and must boxing between cut-off waveguide window 35 and the shield shell, in case electromagnetic-wave leakage.Below be that example details its mounting structure with air outlet 7.
Shown in accompanying drawing 8, the main body of air outlet 7 is a casing 30 that is embedded in the ceiling 2.In the inside of casing 30 filter 33 is installed.The mounting structure of the filter 33 of the mounting structure of this filter 33 and common toilet inner wind outlet is as good as, so do not give unnecessary details at this.The air inlet 31 of casing 30 is connected with airduct outside the toilet through flange, and the bottom of air outlet 32 is equipped with diffuser plate.And improvements of the present invention are, the cut-off waveguide window 35 that plays electromagnetic shielding action are installed in the inside of casing 30.
The shell of casing 30 adopts the metallic plate bending to be welded, and the whole continuous welding in the border of interior boundary and cut-off waveguide window 35 is not stayed the gap together.Cut-off waveguide window 35 is made up of cellular board, and its waveguide cutoff frequency is greater than the frequency of required shielding, thereby plays electromagnetic shielding action.
Cut-off waveguide window 35 is installed in the top of filter 33, and between the two, closely seamlessly is folded with a circle sealing gasket 41, plays the clean effect of sealing, thereby makes and set up the clean usefulness that cut-off waveguide window 35 can not influence clean air outlet.
The bottom of casing 30 turn on one's side out outwardly one the circle fixed edge 45, this fixed edge 45 is attached on the lower surface of ceiling 2.
This air outlet 7 also comprises the metal connection box 36 of a ring-type, and the section of this connection box 36 is the L font, possesses rectangular first joint face and second joint face each other.Wherein, first joint face is close on the outer wall of casing 30, and dead through the full weld weldering.Second joint face is close on the upper surface of ceiling 2, and is also dead through full weld weldering, thereby makes contacting of realization continuous conduction between ceiling 2 and the casing 30, and then makes the connection of continuous conduction mutually between ceiling 2 and the cut-off waveguide window 35.
Pass second joint face, ceiling 2, fixed edge 45 and be provided with many group bolts, and through with realize being fixedly connected between casing 30 and the ceiling 2 cooperating of nut.
Through above-mentioned connected mode, the weight of whole air-supply 7 can directly not born by the point of having fixed bolt on the ceiling 2, but passes through connection box 36 indirect securement on ceiling 2, makes weight disperse.Shown in accompanying drawing 1; At the top of casing 30 a plurality of suspension ring 46 can also be set, in suspension ring 46, draw and establish lacing wire, be dissipated on other bearing walls through the weight fraction of lacing wire with whole air-supply 7; Alleviate the load-bearing burden of ceiling 2 more, strengthened the reliability of sealing.
All seam crossings all adopt full weld to connect in the whole box body 30, and the finally necessary all zinc-plated or copper plating treatment of product, guarantee its shield effectiveness.
Air outlet in the shielding toilet of traditional double-deck body of wall; Its cut-off waveguide window 35 is installed in the shielding body of wall in the outside; Clean filter is arranged in the clean wall of internal layer; Connection airduct length between the two-layer body of wall is longer, all has the installation slit on the double-deck body of wall, has increased risk of leakage.In the air outlet 7 in the present embodiment, the 35 direct boxing of cut-off waveguide window are in the inside of casing 30, reduced and body of wall 1 between the installation slit.Simultaneously, through fixed edge 45 and connection box 36 are set, the further perfect clean usefulness of whole air outlet 7.
In the occasion that need inside and outside the toilet, carry out fluid exchange, the water pipe 9 that passes body of wall 1 need be installed also.The shielding mode of water pipe 9 is identical with air outlet 7, on the pipeline cross section, sets up a cut-off waveguide 35, and this cut-off waveguide window 35 is connected with the shield shell boxing, can realize shielding.
Shown in accompanying drawing 9, electric wire 81 and cable that all pass in the body of wall 1 introducing toilet all must filter through wave filter 80.
After designing toilet according to mentioned above principle, also need calculate and check its shield effectiveness with shielding action.The validity of shield is measured with shield effectiveness.Shield effectiveness SE satisfies following formula:
SE＝A+R+B
A＝1.314*t(f*σ
r*μ
r)
1/2
R＝168-10log(μ
r*f/σ
r)
B＝20log{1-[(Zm-Zw)/(Zm+Zw)]
210
-0.1A(cos0.23A-jsin0.23A)}
In the formula:
A---absorption loss
R---reflection loss
B---reflection loss repeatedly
F---wave frequency Hz
σ
r---relative conductivity
μ
r---relative permeability
T---shielding material thickness, the cm of unit
The electromagnetic wave impedance of Zm---shielded metal
The electromagnetic wave impedance of Zw---air
When A＞10dB, generally can disregard repeatedly reflection loss.So the shielding efficiency can be reduced to:
SE＝A+R
Parameter is according to t=0.5mm; σ r=0.17; μ r=1000 substitution estimation; The shield effectiveness verification characteristics frequency far field result of calculation of pressing the GB/T12190-2006 recommendation is as shown in table 1, and visible its effectiveness of toilet by this structural design is goodish, can use as the standard shielded chamber fully.
