Description

A kind of Airshower chamber

Technical field

The utility model relates to air cleaning facility, is specifically related to a kind of Airshower chamber.

Background technology

Existing Airshower chamber is mostly simpler and cruder, such as a kind of Airshower chamber related among the Chinese patent ZL200420044672.4, comprise shell, enter, go out, blower fan, high efficiency particulate air filter, some gas nozzles and air return system, gas nozzle is arranged on the interior side wall body of Airshower chamber, and air return system is arranged on the body of wall of the relative side of gas nozzle.Though under the situation of normal running, also can satisfy the use needs, because operating personnel's maloperation, cause the relatively poor even situation that can not effectively play a role of the dust removing effects of Airshower chamber to happen occasionally.Such as when not closing the door in the outside, having opened inboard door, cause the dust in the outside air to enter in the toilet with air as the people who enters Airshower chamber.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of Airshower chamber and overcomes the deficiencies in the prior art.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of Airshower chamber comprises the room and the wind of drying in the room is drenched system that the room has left side wall, right side wall, ceiling, floor, external door, inside door, also is provided with the interlock that prevents that inside door and external door from opening simultaneously.

In the optimized technical scheme, described interlock comprises that being arranged on external door first switch and first electromagnetic force on one side locks, and is arranged on inside door second switch and second electromagnetic force lock on one side; And the programmable logic controller (PLC) that is electrically connected with described blower fan, first switch, the first electromagnetic force lock, second switch, second electromagnetic force lock; Programmable logic controller (PLC) makes the moving part of second electromagnetic force lock withdraw when first switch closure, and the blower fan entry into service; And the moving part of the electromagnetic force lock of winning is withdrawn.

Further, described wind pouring system comprises the blower fan that is electrically connected with described programmable logic controller (PLC), and is electrically connected with blower fan, the timing unit of control blower fan duration of runs.

Further, also be included in and make second electromagnetic force lock delay-action delay unit after blower fan shuts down.

Further again, also comprise reminding unit; Described reminding unit is electrically connected with programmable logic controller (PLC), sends prompting after the action of second electromagnetic force lock.

Concrete, described reminding unit is loudspeaker or indicator lamp.

Described reminding unit also can both comprise loudspeaker, also comprised indicator lamp.

In the optimized technical scheme, also be provided with air inlet on the described ceiling.

The beneficial effect that Airshower chamber of the present utility model is compared with the prior art is:

Owing to be provided with interlock, make inside door and external door can not open simultaneously, the possibility of effectively having avoided the toilet to be polluted by outdoor air.

Owing to adopt programmable logic controller (PLC) to cooperate switch and electromagnetic force lock to realize electromagnetism interlocking, simple in structure, reliable operation.

Owing to comprise timing unit, can control the running of blower fan by setting-up time, also effectively guaranteed dust removing effects.

Owing to be provided with delay unit, also make indoor remaining small amount of dust fall for some time after making blower fan stop, dust removing effects is better.

Owing to be provided with alarm set, remind the staff can open inside door after the dedusting end-of-job and enter the toilet, thereby convenient and hommization.

On ceiling, also be provided with air inlet, can comprehensive dedusting, because dust removing effects is high better.

Description of drawings

Fig. 1 is the Airshower chamber structural representation of the utility model specific embodiment;

Fig. 2 is the schematic diagram of the utility model specific embodiment.

The specific embodiment

As shown in Figure 1, the Airshower chamber of this specific embodiment comprises the room 1 of square frame shape, and room 1 has left side wall 2 and right side wall 3, and ceiling 4 and floor 5, offers a plurality of air inlets 6 on the top of ceiling 4 and left side wall 2, right side wall 3.Air enters room 1 by air inlet 6 under the driving of blower fan 8, and from the air outlet 7 of left side wall 2 and right side wall 3 bottoms the particulate matters such as dust on the article and the person the room 1 is taken away.Can also in the gas circuit that air is flowed through air cleaner be set, the air that comprises dust is gone into blower fan 8 and recycling through air cleaner is laggard.

By Figure 2 shows that this Airshower chamber principle schematic, as seen from Figure 2, the outside in room 1 is provided with external door 9 inboards and is provided with inside door 10, one side at non-hinged first switch 11 and first electromagnetic force lock 12 of being provided with of external door 9; The corresponding second switch 15 and second electromagnetic force lock 14 that also is provided with on one side of inside door 10.First switch 11, first electromagnetic force lock 12, second switch 15 and second electromagnetic force lock 14 all are electrically connected with programmable logic controller (PLC) 13.Programmable logic controller (PLC) 13 also is electrically connected with blower fan 8, the work of control blower fan 8.First switch 11 and second switch 15 can be travel switch, when door is closed, trigger its action, programmable logic controller (PLC) 13 is controlled the action of first electromagnetic force lock, 12, second electromagnetic force lock 14 and blower fan 8 according to the state of first switch 11 and second switch 15.

Timing unit of this Airshower chamber and delay unit all are included among the programmable logic controller (PLC) 13, when the people enters room 1 and closes external door 9, and first switch, 11 closures, blower fan 8 is started working simultaneously, to room 1 air-supply.When air-supply that programmable logic controller (PLC) 13 is set after time is up, out-of-blast such as blower fan 8 after 30 seconds; Again through certain hour time-delay, stopped for ten seconds such as blower fan 8 after, programmable logic controller (PLC) 13 makes 14 actions of second electromagnetic force lock, its moving part withdrawal, this moment, inside door 10 was in openable state.In addition, programmable logic controller (PLC) 13 also is connected with reminding unit.Described reminding unit is loudspeaker 16 herein.When the moving part of second electromagnetic force lock 14 was withdrawn, programmable logic controller (PLC) 13 made loudspeaker 16 send prompt tone, and the people's dedusting in the prompting room 1 finishes, and can open inside door 10 and enter the toilet.Reminding unit also can adopt indicator lamp, can certainly indicator lamp also be arranged existing loudspeaker 16, then can carry out acousto-optic and remind better effects if.

And entering into room 1 when the people of the inside opens inside door 10, external door 9 is in locking state, cannot be opened.Close after the inside door 10, programmable logic controller (PLC) 13 can't make blower fan 8 open, but makes the moving part withdrawal of the electromagnetic force lock 12 of winning when inside door 10 is closed, and this moment, external door 9 promptly can be opened.

Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
