Description
Technical field
The present invention relates to toilet's technical field, it is more particularly related to the energy-conserving cleaning chamber of a kind of air-flow equilibrium.
Background technology
The pollutant such as the micropartical in air, noxious air, antibacterial are reduced to specify in the range of referring to certain space by toilet
Below index, and by indoor temperature, humidity, cleanliness factor, air velocity and air flow method, noise and vibration and illumination, quiet
Electric control is specially designed room in a certain range of needs.Toilet has a wide range of applications in modern production technology,
In occupation of very important status, but the air flow method in the most a lot of toilet is uneven, and the air after purified treatment is from cleaning
Upper end, room is from top to bottom sent to inside toilet, and the air pressure near air outlet slit is higher than the air pressure of peripheral space air,
Cause near air outlet slit, entering the air-flow velocity within toilet and enter the flow velocity within toilet more than surrounding, thus exist
Vortex phenomenon, causes indoor gas circulation not thorough, causes cleanroom cleanliness grade to decline, in order to improve cleanliness factor,
The rate of ventilation of toilet must be increased, namely add the intake of new wind, so that the energy consumption of Fresh air handling units is greatly
Increase;
On the other hand, if the air used is the occupation mode of full process, full discharge, its wasting of resources is very big, because of
And after the air in the general employing circulated air that all needs in toilet, i.e. collection toilet carries out humid heat treatment, again return to cleaning
Indoor are circulated utilization, and this is accomplished by Cycle Unit.Thus, the effect of Cycle Unit is the clean Interior Space that will collect
After gas carries out humid heat treatment, return again to be circulated use to toilet.But the power saving of toilet's air cleaning and conditioning system
One of return air stream in toilet not science is set, typically result in indoor-outdoor air circulation thorough, occur cross-ventilation,
Eddy current, affects ventilation effect, needs that ceaselessly carrying out takes a breath and can be only achieved the cleaniliness classs of indoor, add returning of indoor
Air quantity, needs substantial amounts of new wind to replace indoor original air, increases the energy consumption of Cycle Unit and Fresh air handling units simultaneously,
If the intake of resh air requirement is excessive, and in air cleaning and conditioning system, energy consumption is mainly on new wind, will make the energy consumption of air conditioning system
Increase further.
Summary of the invention
It is an object of the invention to solve at least the above, and the advantage that at least will be described later is provided.
It is a still further object of the present invention to provide the energy-conserving cleaning chamber of a kind of air-flow equilibrium, bottom toilet, be provided with first

Avoid air at indoor generation eddy current, optimize the air flow path of indoor;And
Silenced fan 150, it is arranged on described ceiling center, and the air inlet of described silenced fan goes out with described Cycle Unit
Mouth connection, the gas outlet of described silenced fan connects with toilet's headroom, and new wind exports with ventilation mouth after treatment
After circulation air mixing, after Cycle Unit processes, enter into indoor from silenced fan.
Being provided with the first return air channel bottom toilet, described first return air channel bottom center is provided with and described first time
The return air unit of wind channel connection, for emitting indoor dirty gas;Top, toilet is provided with the second return air
Passage, toilet's side wall of top board surrounding offers return air inlet, and the center of top at the second return air channel is provided with ventilation mouth,
Ventilation mouth essentially identical with the distance of the return air inlet being arranged on surrounding, the gas at top, toilet can equalize from return air inlet
Being pumped in the second return air channel, the air of extraction is after preliminary filtration, by being arranged on changing of the second return air channel central authorities
QI KOU is taken in and is carried out senior filtration in Cycle Unit, mixes with new wind afterwards and takes in toilet, thus fully circulates profit
With indoor air resource, ensure indoor air-changing number of times and cleanliness factor in advance under, reduce the intake of new wind, from
And save the energy consumption of Fresh air handling units.And the upper end of toilet is provided with current-sharing air outlet, is provided with bottom toilet
Inside setting the base plate that leaks out of equal wind net, the air intake of toilet, by the top, entrance toilet of the post-equalization of current-sharing air outlet, is assembled
Dirty gas bottom toilet is extracted out by return air unit by base plate equilibrium of leaking out, say, that air is by all flowing out
Air port and base plate equilibrium of leaking out by inner space, toilet, it is to avoid eddy current produces and the deposition of dirty gas, and indoor change
Gas is in hgher efficiency.Toilet's surrounding and bottom are provided with heat exchanger channels simultaneously, are internally provided with heat exchanger tube, from the bottom of toilet
The dirty gas that portion extracts out is discharged in heat exchanger channels and carries out heat exchange, afterwards new wind quilt with the circulation new wind in heat exchanger tube
Take in Cycle Unit, make full use of the energy consumption discharging waste gas, save the energy consumption of Fresh air handling units.
In a kind of embodiment, described crown wall, side wall and end side within the walls is provided with certain thickness heat-insulation layer, and heat-insulation layer serves
Insulation effect, decreases the energy consumption of air conditioning system, and return air inlet is opened in described heat-insulation layer, it is to avoid directly contact with side wall,
Reduce heat radiation.
In a kind of embodiment, described in leak out and be provided with equal wind net on base plate, the air inlet of described silenced fan is from described crown wall

Being provided with current-sharing air outlet, set the base plate that leaks out of equal wind net bottom toilet in being provided with, the air intake of toilet passes through current-sharing
The top, entrance toilet of the post-equalization of air outlet, is gathered in the quilt by base plate equilibrium of leaking out of the dirty gas bottom toilet
Return air unit is extracted out, air by current-sharing air outlet and base plate equilibrium of leaking out by inner space, toilet, it is to avoid eddy current
Producing and the deposition of dirty gas, indoor air-changing is in hgher efficiency, decreases the energy consumption of Fresh air handling units and improves toilet's cleaning
Degree grade.
In another kind of embodiment, being provided with confined space between described current-sharing air outlet and described base plate, silenced fan is discharged
Air is taken in confined space, forms malleation space, and the air in confined space is taken in room after current-sharing air outlet current-sharing
In, thus the entrance of air equilibrium is indoor, it is to avoid air-swirl, convection current in forming chamber, described return air inlet connection described second
Return air channel and the clean room space of described current-sharing air outlet lower end, the air of current-sharing air outlet lower end is back to by return air inlet
In second return air channel.
In another kind of embodiment, described return air inlet is provided with primary filter, described ventilation mouth is provided with middle rank filter,
Described Cycle Unit is provided with senior filter, carries out, progressively after purified treatment, again carrying from the air of return air inlet backflow
