Description

For the channel switching device and airhandling equipment in fluid line

Technical field

The present invention relates to airhandling equipments, and in particular, to a kind of channel switching device in fluid line, this Outside, the invention further relates to a kind of airhandling equipments.

Background technology

Atmosphere polluting problem has increasingly been highlighted in today's society, seriously endangers the health of people, in order to cope with Worsening atmosphere polluting problem, all kinds of airhandling equipments are widely used in family, office building, hospital, school etc., Middle aeration device is to apply a kind of airhandling equipment more stronger than wide, practicability.Product is main in fresh air industry at present Based on central fresh air system, in addition to this, wall-hanging, cabinet type new wind turbine, the new wind turbine of wall-penetrating type are also applied more.

Central fresh air system includes being installed on the host and blast pipe and discharge pipe of indoor top, foul indoor air warp Discharge pipe discharge is indoor, and outdoor fresh air is sent into interior through blast pipe after the main emission controls by improving combustion of fresh air.One inside fresh air host As setting wind turbine and filter screen, wind turbine includes air-introduced machine and exhaust blower to realize two-way circulating for air-flow, some further include full heat Exchanger realizes that the portion temperature of room air and outdoor air exchanges simultaneously adjusting air humidity.

Wall-hanging and cabinet type new wind turbine are that the components such as wind turbine and strainer are integrated in a machine to be formed on host, the host It is typically mounted at interior, by being connected into and out of pipeline with outdoor, general pipeline is shorter, is hidden in invisible in wall.Wind Machine is divided into air-introduced machine and pressure fan, and air-introduced machine, which passes through the air port around host shell and introduces foul indoor air, when work is discharged room Outside, pressure fan introduces outdoor fresh air feeding interior after filter assemblies (generally multistage strainer) by admission line. In addition, higher wall-hanging is configured and cabinet type new wind turbine generally installs total-heat exchanger additional, to realize room air and outdoor air Portion temperature exchange and adjusting air humidity.

The new wind turbine of wall-penetrating type, is generally mounted on wall or glass, by punching (general diameter on wall or glass 15cm or more) so that new wind turbine is positioned over wall or inside glass, introducing outdoor air by inner fan passes through filter assemblies (strainer) is sent into interior, and this new wind turbine of wall-penetrating type is generally the one-way flow of air-flow, some products are by controlling fan just The a degree of intermittent interior of reversion realization is exchanged with outdoor air.

Above-mentioned center fresh air system, needs to install a large amount of blast pipes and exhaust duct, destroys family's interior trim, greatly occupy house Front yard space.For wall-hanging and cabinet type new wind turbine, although saving ventilation shaft to a certain degree, its take up space it is larger, Machines cumbersome, power is also larger, and energy consumption is excessively high, uses very uneconomical.The new wind turbine of wall-penetrating type generally by strainer into Row filtering, the efficiency once filtered are low, it is difficult to meet the requirement of fresh air, and due to needing integral installation in wall hole, for The diametric requirements of wall hole are excessively high, and practicability reduces, and seriously affects the selection of consumer.

In addition, above-mentioned center fresh air system, wall-hanging and cabinet type new wind turbine are in addition to using strainer as air deduster Except, it is some of also to use electrostatic dust collection equipment as air deduster, but these electrostatic dust collection equipments be confined to it is quiet The natural mode that electric field is formed uses the plate of traditional parallel interval opposed type to form electrostatic field, leads to these new wind turbines It is bulky, occupied space is excessive, and wait for the air stream of dedusting it is straight quickly through, frequently result in air cleaning efficiency compared with Low, the New atmosphere quality of introducing is often inferior, influences health, this causes the new wind turbine using these electrostatic dust collection equipments in city Acceptance is relatively low on field.In addition, using electrostatic dust collection equipment new wind turbine there is also some influence health, those skilled in the art Long-term indiscoverable recessive hazard factor, leading to these new wind turbines, there are larger security risks.

More seriously, the defect that the new wind turbine generally existing of the above-mentioned type has a single function only has air outer circulation Function not only aggravated the work load of new wind turbine filter assemblies in the case of extraneous air serious haze, make its be easy Damage, and from external suction and by filtered air quality even not as good as indoor original air quality.In view of this, existing There is the new wind turbine with interior circulatory function there is also some relative coarseness in technology, for example, some new wind turbines are interior in order to be formed Circulating working mode, using two wind turbines it is respectively relatively independent form interior circulation pattern and outer circulation pattern, this is not only not gram The above-mentioned existing defect of existing new wind turbine is taken, and causes new blower fan volume huger, structure is more complicated, and air duct is laid with more Add complicated.In addition, also having some wall-hangings and cabinet type new wind turbine directly to open up an indoor air inlet on body indoors, pass through The switching cover board of internal body selectively blocks the external air inlet of indoor air inlet or the external intake stack of connection, to realize The switching of outer circulation operating mode and interior circulating working mode, still, there is no change wall-hanging and cabinet type for this structure type The essence of new wind turbine, the interior space is big, heavy, and the excessively high defect that consumes energy does not change, even more serious for intrinsic occupying It is this coarse way for directly opening up indoor air inlet in wall-hanging and on the indoor body of cabinet type new wind turbine, can causes to bang The major defects such as ring, filtration members damage, air endless loop.Specifically, due to the indoor host computer of wall-hanging and cabinet type new wind turbine Inlet chamber is generally large, directly opens up indoor air inlet on host indoors, indoor air inlet is closer apart from wind turbine distance, through wind The room air of machine suction can be buffered unlike outside air inlet via external intake stack, directly get in host at a high speed Inlet chamber in, cause indoor body to tremble, even thunder, simultaneously because room air via wind turbine powerful suction not Buffered high-speed impact filtration members, cause filtration members to be easily damaged, and can not play good filtration.Once filtration members are damaged Bad, filtration members can not effectively act as the effect of limitation air outlet velocity, and the flow velocity of air inlet and the outlet tends to be close, verifies, Easily form the endless loop of room air in the subrange around host indoors at this time, i.e. wall-hanging and cabinet type fresh air at this time The interior circulating working mode of machine can not effectively purify the air of a room substantially, be in invalid state.

The drawbacks described above of new wind turbine has formed and has restricted the technical bottleneck that new wind turbine further develops, some hazard factors Those skilled in the art are unaware that there are hidden troubles so far, specifically how so that new wind turbine is having both inside and outside circulation industrial On the basis of operation mode, it is effectively saved the interior space, working performance is well reliable, has become the technical barrier of this field.

In preferred embodiment below, the channel switching device of the present invention is applied to a kind of with double working modes Airhandling equipment wall pipe in, wherein the present invention channel switching device the advantages of will more specifically be shown.

As previously mentioned, to realize double working modes, and compact integral structure, occupying little space, working performance is steadily reliable, Wall hole formula airhandling equipment is embedded the present invention provides a kind of novel air processing equipment, especially Two-way Cycle, at the air Reason equipment includes air hose and is exposed to indoor indoor body, as shown in figure 17.Particularly, the present invention is formed with outdoor in air hose Air by purification air hose internal channel and room air circulation Interior Space tracheae internal channel, from may be not present it is at random into Air hose, exhaust duct etc., complete machine structure is simple, compact, as shown in Figures 3 to 5.At this point, indoor body is equipped with the outlet of purification wind, room Interior air intake and air suction device 15.Wherein, air hose can be the common blast pipe of various airhandling equipment, but with In lower description taken in conjunction with the accompanying drawings, air hose is preferably the wall pipe in wall hole.

Wherein, airhandling equipment further includes air duct switching device and air cleaning unit, and air duct switching device is for selecting Interior Space tracheae internal channel or purification air hose internal channel is uniquely connected to selecting property, to make airhandling equipment correspondingly switch Work in interior circulating working mode or air inducing operating mode；I.e.：

Under interior circulating working mode, room air is under the effect of air suction device 15 from indoor air inlet into entering the room Interior air hose internal channel is simultaneously expelled to interior after air cleaning unit purifies from the outlet of purification wind；

Under air inducing operating mode, outdoor air under the effect of air suction device 15 from the axially outer end of air hose (i.e. Fig. 1, Paper right end shown in Fig. 2, similar below) enter purification air hose internal channel and after air cleaning unit purifies from purification Wind outlet is expelled to interior.

After forming purification air hose internal channel and Interior Space tracheae internal channel in air hose, the circulation path of air-flow is longer, Even if purification air hose internal channel or Interior Space under the strong pumping effect of air suction device 15 if air-flow in air hose Comfort cushioning is obtained in tracheae internal channel, it is small to the impact of complete machine, it is mainly reflected in wall-penetrating type generating impact and fixes and pacify It is small to the impact endurance test shock of complete machine in the air hose of dress.

In addition, the air suction device 15 in the embodiment of Fig. 1 is preferably single aerofoil fan, airhandling equipment The outlet of purification wind and aerofoil fan are axially aligned in the interior shaft end of air hose, this is because purification air hose internal channel and room air Pipe internal channel is integrated in air hose, and air stream outlet need to only be arranged single all in the interior shaft end of air hose in the interior shaft end of air hose A wind turbine, and the two fans structure of unconventional Two-way Cycle airhandling equipment, in other words, wind turbine can share so that structure assembly Degree is high.In addition, following will also address, since purification air hose internal channel and Interior Space tracheae internal channel compact Layout are in air hose Interior, air flow path is long, and air cleaning unit is also able to compact Layout.

For realize design compact-sized, path length in air hose and the purification air hose internal channel that can switch in due course and Interior Space tracheae internal channel, those skilled in the art are readily apparent that the shape using built-in double parallel pipe or more pipe in air hose Formula, however this certainly will require the caliber of air hose big, disclosure satisfy that air quantity demand.For accomplish it is compact-sized and maximize increase into Air quantity, embedded wall hole formula airhandling equipment of the invention use the sleeve structure including inner tube 1 and outer tube, inner tube tube chamber and Any one of perimetrical lumen 6 between inner and outer pipes is purification air hose internal channel, i.e. outdoor air can be from the outer shaft of air hose End enters inner tube tube chamber or perimetrical lumen 6, is then flowed out from corresponding interior shaft end.

At this point, the other of inner tube tube chamber and perimetrical lumen 6 constitute Interior Space tracheae internal channel or at least constitute indoor A part for air hose internal channel.When due under double working modes, purifying the connection of air hose internal channel to enter outdoor air, room Interior air hose internal channel needs to close, and similarly, when Interior Space tracheae internal channel is connected to, purification air hose internal channel needs to close. At this point, in view of in the indoor air inlet setting under interior circulation pattern indoors body, thus relatively reasonable air duct arrangement Mode is can only to enter then to wrap to interior shaft end outflow from the interior shaft part of air hose.Therefore, Interior Space tracheae internal channel may include The inner tube tube chamber and perimetrical lumen 6 of inner tube 1, the room air that indoor air inlet enters is via inner tube tube chamber and perimetrical lumen 6 One of interior shaft end enter in air hose, then from axially outer end can enter another one intracavitary, preferably out of this another one It flows out shaft end.Not only flow is longer in this way, but also under either interior cycle or air inducing operating mode, at least part is logical in air hose Road be room air and outdoor air share flow through place jointly, to also just facilitate the densification cloth of air cleaning unit It sets, needs be only arranged in shared runner.

On this basis, to realize Interior Space tracheae internal channel and purifying the in due course switching of air hose internal channel, from function It is divided in principle, air duct switching device should include two switching valves controllably, can open in due course to introduce outdoor air It citation damper and can open in due course to be connected to inner tube tube chamber and perimetrical lumen 6 (to be constituted complete Interior Space tracheae internal channel) Communicating valve.Wherein, citation damper should be arranged in the axially outer end end face of purification air hose internal channel, purify air hose internal channel at this time Interior shaft end be connected to air suction device 15, with provide power suction air enter.Meanwhile in inner tube tube chamber and perimetrical lumen 6 Another one interior shaft end communication chamber in air intake, axially outer end and perimetrical lumen 6 in inner tube tube chamber should be arranged in communicating valve Between axially outer end.
