In addition, in patent documentation 4, disclose and in the off-premises station of air conditioner, be equipped with for exhaust apparatus, and have and to supply the exhaust converting member by rotation, switch for the exhaust passage, outdoor air is drawn into indoor air feed function and room air is discharged to outdoor degassing function, and with the separate type air conditioner of humidification for exhaust apparatus.
Be documented in the humidification among first embodiment of above-mentioned patent documentation 1, ventilation, dehydrating unit, be provided with the whole heat exchanger of rotation lentamente is divided into, the humidification part in following two districts and dehumidifying part, with pressure fan (usefulness of will taking a breath, the fan of using for exhaust is referred to as pressure fan, the fan that will ventilate to the heat exchanger of the indoor set of air conditioner is referred to as primary air fan) room air is sent in these two parts, room air is after dividing by humidification part or dehumidification portion, in the part return chamber, another part is sent outdoor, thereby can outside the exhaust ventilation, realize the function of humidification or dehumidifying simultaneously.
The switching of humidification or dehumidifying is that the butterfly by the downstream that is arranged on total heat exchanger carries out, when on the position that butterfly is placed humidification, the humidification part of total heat exchanger is communicated with exhaust outlet to indoor exhaust, simultaneously, dehumidifying part by making total heat exchanger is communicated with the exhaust outlet to outdoor exhaust, thereby it is indoor that air behind the humidification is turned back to, and make the air after the dehumidifying be discharged to outdoor.When on the position that butterfly is placed dehumidifying, the humidification part of total heat exchanger is communicated with exhaust outlet to outdoor exhaust, simultaneously, dehumidifying part by making total heat exchanger is communicated with the exhaust outlet to indoor exhaust, thereby it is indoor that air after the dehumidifying is turned back to, and make the air behind the humidification be discharged to outdoor.
Usually, carrying out air feed when running, though the importing of air that will be outdoor is indoor, outdoor air by the situation that various material polluted under, the air that is imported can make to be lived in indoor people and feels bad.In order to eliminate this condition of poor, the most handy filter purifies importing indoor air.The air conditioner of first embodiment of above-mentioned patent documentation 1, its ventilatory only is a degassing function, have only two kinds of selections the air channel being carried out humidification or dehumidifying, to the air feed problem but without any consideration, as air interchanger, in air feed and this two big function of exhaust, only has the function of half.
In addition, in the air conditioner of first embodiment of patent documentation 1,, must estimate that the passage that sucks air strengthened necessary size is installed when mounted, thereby lose the free degree of installing interior because the suction inlet of ventilation air is arranged on the side.Also have, owing to the exhaust outlet of outwards exhaust is arranged on the top of machine body, so, just need be different with refrigerant tubing, the condensing water conduit of drawing from the bottom of the common machine body of wall air conditioner in addition in the hole that wall is offered, it is pretty troublesome that installation exercise becomes.In addition, humidification, ventilation, dehumidifying parts are given prominence to a lot to the side of the indoor set of air conditioner, make the whole width size of air conditioner increase.
In addition, in the air conditioner of first embodiment of patent documentation 1, when the ventilation running stops, not cutting off indoor and outdoor mechanism, under outdoor situation such as blow hard, will produce strong wind and blow into indoor next problem.
The pressure fan of the ventilation usefulness in the air conditioner of above-mentioned patent documentation 2 is by the direction of rotation of pressure fan is converted to reverse rotation and changes air supply direction from being rotated in the forward, to carry out the running of exhaust running and air feed.
When carrying out air feed when running, outdoor air is imported indoor, outdoor air by the situation that various material polluted under, the air that is imported can make to be lived in indoor people and feels bad.In order to eliminate this condition of poor, the most handy filter purifies importing indoor air.The air conditioner of above-mentioned patent documentation 2, no matter pressure fan is when just changeing or when counter-rotating, all allows air by being arranged on the filter of the usefulness that purifies air in the pipeline.
; as the air conditioner of this patent documentation 2; the ventilating surface of the filter of the usefulness that purifies air is arranged to parallel with the driving shaft of pressure fan; when making the performance that filter has with ventilation volume conforms to of this usefulness that purifies air, in order to ensure the area of the filter of the usefulness that purifies air, the width of the pipeline of ventilation usefulness becomes very big; and the heat exchanger that matches therewith must be done very for a short time; as a result, as the basic purpose of original air conditioner, the ability of promptly regulating temperature and humidity has but reduced.Under the situation of the size that does not change heat exchanger, there is the too big such unsuitable problem of shape of indoor set again.
In addition, under the situation of room air being sent outdoor exhaust running because to the air of outdoor discharge will be by the usefulness that purifies air filter, exhaust the time flowing resistance increased, the air capacity of discharge can reduce, and also wishes to improve this situation.
In addition, under situation with the running of the air feed in the outdoor air suction chamber, when turning round, exhaust is captured in all contaminations in the room air on the air cleaning filter, just owing to air cleaning filter is left in the counter-rotating of air supply direction, along with the air of confession send into indoorly, be very bad situation.
In addition, in the air conditioner of patent documentation 2, because the pressure fan of ventilation is a vortex flow fan, noise is very big, if increase the diameter of pressure fan in order to reduce noise, then the overall dimensions of air conditioner will increase, and occupy the whole section of indoor set.Like this, just the control part of the employed electrical equipment of the indoor set necessary part that grades has not been contained in the space on the bottom of ventilation pressure fan and top, has had to do indoor set very greatly.

In addition, though be not described in detail, the switching of various operation modes under manual situation, can be carried out with the operation part of remote control switch, or carry out with the operation part of indoor set 1.In addition, under situation about automaticallying switch, then the instruction of sending according to control section 17 is carried out.The running of air-supply arrangement 20 both can be carried out with the refrigeration heating running of indoor set 1, also can be carried out separately by air-supply arrangement 20.Also have, also timer can be set in air-supply arrangement, behind the certain hour that turned round, can shut down automatically.
As shown in Figure 8, because air-supply arrangement 20 employed pressure fans 33, be to the rotation of certain direction, make air flow, so make air mobile just passable to a direction as long as consider suction chamber 31, the shape of sending chamber 32, import ring 31b made to the direction shown in the arrow.Like this, not only can improve the air-supply efficient of pressure fan 33, the noise in the time of can also reducing pressure fan 33 runnings.
By making 40 rotations of air channel switching device shifter, the air channel that sucks air is switched to the air channel that sucks room air from suction inlet 21a, or switch to the air channel of sending piping connection portion 23a suction chamber outer air from suction; Simultaneously, the air channel of discharging air switch to from air feed send mouthfuls 13 air to the indoor air channel of sending, or send the air channel of piping connection portion 23a to outdoor discharge air from suction; Just can switch to any pattern in air feed running, exhaust running and these three kinds of patterns of cycle operation to the operation mode of air-supply arrangement 20.
Promptly, in the air feed running, because air channel switch piece 41 is on the A of position, be cut off between suction chamber 31 and the suction subsidiary conduit 21, be communicated with and send subsidiary conduit 23 with suction, institute is so that send subsidiary conduit 23, prefilter 24, air intake filter 36 and inlet channel 35 suction chamber outer air by suction.Have again owing to send chamber 32 and send subsidiary conduit 22 and be communicated with, so the outdoor air that is sent just wind is delivered to send subsidiary conduit 22, send piping connection portion 22a, air feed sends in the pipeline 12, send mouth 13 from air feed and deliver to indoor.
Under the situation of present embodiment, the outdoor air that is sucked by pressure fan 33, by yard piping 15, send piping connection portion 23a from suction again and send pipeline 23 suctions by suction, remove after the dust contained in the air by the surface of prefilter 24, remove dust contained in the air and harmful material by the surface of air intake filter 36 again, after passing through air intake filter 36, introduce in the inlet channel 35, sucked by pressure fan 33, then, just by send subsidiary conduit 22 from air feed send mouthfuls 13 pass out to indoor.
In addition, in exhaust running, air channel switch piece 41 is on the B of position, because suction chamber 31 is communicated with sucking between the subsidiary conduit 21, institute is so that by filter by suction 21b, suction subsidiary conduit 21 suction room airs.Then, owing to send chamber 32 and send partition between the subsidiary conduit 22, send pipeline 23 with suction and be communicated with, flow into the yard piping 15 and be discharged to outdoor so the room air that is sent is sent piping connection portion 23a by going into to send pipeline 23, prefilter 24 from suction.
In addition, in cycle operation, air channel switch piece 41 is on the C of position because suction chamber 31 is communicated with sucking between the subsidiary conduit 21, institute so as to pass through filter by suction 21b, suction subsidiary conduit 21, with in the room air suction draft machine 33.Have again owing to send chamber 32 and send subsidiary conduit 22 and be communicated with, so the outdoor air of sending out from pressure fan 33 just wind is delivered to send subsidiary conduit 22, send piping connection portion 22a, air feed sends the pipeline 12, send mouth 13 from air feed again and deliver to indoor.
In addition, when shutting down, air channel switch piece 41 is on the D of position, prevents that outdoor air is by sucking subsidiary conduit 21, sending in subsidiary conduit 22 inlet chambers.Like this, just there is no need when shutting down, to be set to prevent that outdoor air from sending the contrary wind that pipeline enters by suction and preventing parts such as valve.
Then, mainly with reference to Figure 10, Figure 15 and Figure 16, the details when the air feed running is described.
During the air feed running, as Figure 10, Figure 15 and shown in Figure 16, drive 41 rotations of air channel switch piece by drive unit 47, make respectively to suck and send dual-purpose opening 46c and air inlet suction opening 44a, the opening 46f that air inlet sucking-off opening 44b and air intake filter are used, send into dedicated openings 46e and send into opening 44c, and send opening 43b and send dedicated openings 46b and be on the position that is communicated with.
Adopt such structure, suction chamber 31 just is communicated with following each several part by inlet channel 35: dual-purpose opening 46c is sent in the opening 46f that air intake filter 36, air intake filter are used, air inlet sucking-off opening 44b, airintake wind-tunnel 45c, air inlet suction opening 44a, suction, suction is sent subsidiary conduit 23, prefilter 24, sucked and send piping connection portion 23a, yard piping 15.On the other hand, sending chamber 32 is communicated with following each several part: send into dedicated openings 46e, send into opening 44c, send air channel 45d, send opening 43b, send dedicated openings 46b, send subsidiary conduit 22, send piping connection portion 22a, air feed is sent pipeline 12, air feed sends mouthfuls 13.
Under such state, by pressure fan 33 rotations that make air-supply arrangement 20, outdoor air is just by yard piping 15, sending piping connection portion 23a by suction sucks, enter to be connected and suck the suction send on the dual-purpose opening 46c and send in the subsidiary conduit 23, suck the prefilters of sending in the subsidiary conduit 23 24 and carry out dedusting by being arranged on.Outdoor air after the dedusting flows into to suck and sends in the subsidiary conduit 23, sends dual-purpose opening 46c from suction and enters the air channel switching device shifter 40, and the air inlet suction opening 44a by air channel switch piece 41 flows through airintake wind-tunnel 45c.
Flow into the outdoor air of airintake wind-tunnel 45c, by air inlet sucking-off opening 44b, the opening 46f that uses from air intake filter flows out air channel switching device shifter 40.The outdoor air that the opening 46f that uses from air intake filter flows out enters the adjacent air intake filter holding portion 36c of the opening 46f that uses with air intake filter, again by being contained in the air intake filter 36 among the air intake filter holding portion 36c.In the present embodiment, though air inlet suction opening 44a and air inlet sucking-off opening 44b are independent respectively the settings, but, because each opening is near each other, all same air channel upper shed, and, on each position of rotation of air channel switch piece, can not hinder flowing of air, so these two openings also can be linked to be a big opening.
Enter the outdoor air in the air intake filter 36, utilize the surface of air intake filter 36 to remove dust contained in the air and harmful material, sucking-off from the inlet channel 35 that is communicated with air intake filter holding portion 36c and suction chamber 31, enter suction chamber 31, by being arranged in the import ring 31b suction draft machine 33 on the dividing plate 31a, in pressure fan 33, passing out to after the pressurization and send chamber 32 again.Outdoor air after sending enters the air channel switching device shifter 40 once more from sending into dedicated openings 46e, send into opening 44c by air channel switch piece 41, flow through and send air channel 45d, again by air channel switch piece 41 send opening 43b, flow out air channel switching device shifter 40 from sending dedicated openings 46b.
Flowed out the outdoor air of air channel switching device shifter 40, flow through to be connected to send and send subsidiary conduit 22 on the dedicated openings 46b, piping connection portion 22a is sent in arrival, flow through again and be connected the air feed of sending on the piping connection portion 22a and send pipeline 12, send mouthfuls 13 from air feed and pass out to indoor as fresh outside gas sky.
By such process, from yard piping 15 suction chamber outer air, carry out dedusting with prefilter 24, remove dust contained in the air and harmful material with the surface of air intake filter 36, realized sending mouthful 13 air feed runnings of sending from air feed.Like this, in the transverse width dimension part that following two air channels is contained in air channel switching device shifter 40, thereby can reduce the size of the transverse width of air-supply arrangement 20; These two air channels are, the airintake wind-tunnel 45c from the air inlet suction opening 44a of the suction side of the pressure fan 33 of conveying chamber outer air to air inlet sucking-off opening 44b and send air channel 45b to what send opening 43b from the opening 44c that sends into that sends side of pressure fan 33.
At this moment, though suction chamber 31 is also sent opening 44f with sucking-off dedicated openings 46d, exhaust, exhaust duct 45f is communicated with, owing to do not have the opening of connection before this, so except piping connection portion 23a is sent in suction, can be from other partial-air admissions.
Then, mainly with reference to Figure 11, Figure 17, the details when the exhaust running is described.
During the exhaust running, as Figure 11 and shown in Figure 17, drive 41 rotations of air channel switch piece by drive unit 47, make respectively and suck dedicated openings 46a and suction opening 43a, sucking-off opening 44d and sucking-off dedicated openings 46d send into dedicated openings 46e and exhaust and send into opening 44e and exhaust and send opening 44f and send dual-purpose opening 46c and be on the position that is communicated with sucking.
So, suction chamber 31 just is communicated with following each several part: sucking-off dedicated openings 46d, sucking-off opening 44d, suction air channel 45e, suction opening 43a, suction dedicated openings 46a, suction subsidiary conduit 21, filter by suction 21b, suction inlet 21a.On the other hand, sending chamber 32 is communicated with following each several part: send into dedicated openings 46e, send into opening 44e, exhaust duct 45f, exhaust send opening 44f, suck and send dual-purpose opening 46c, suck and send subsidiary conduit 23, suck and send piping connection portion 23a.
Under such state, by pressure fan 33 rotations that make air-supply arrangement 20, room air just sucks from main suction inlet 5, enters the air-supply arrangement 20 from the suction inlet 21a at indoor set 1 inside opening, by being arranged on the filter by suction 21b that sucks in the subsidiary conduit 21, carry out dedusting.
Room air after the dedusting, enter the air channel switching device shifter 40 from connecting the suction dedicated openings 46a that sucks subsidiary conduit 21, suction opening 43a by air channel switch piece 41, flow through and suck air channel 45e, by the sucking-off opening 44d of air channel switch piece 41, flow out air channel switching device shifter 40 from sucking-off dedicated openings 46d.Room air after sucking-off dedicated openings 46d sucking-off enters the suction chamber 31, is inhaled in the pressure fan 33 by the import ring 31b that is arranged on the dividing plate 31a, and sends chamber 32 by passing out to after pressure fan 33 pressurizations.
The outdoor air of sending out enters the air channel switching device shifter 40 from sending into dedicated openings 46e once more, exhaust suction opening 44e by air channel switch piece 41, flow through exhaust duct 45f, send opening 44f by the exhaust of air channel switch piece 41 again, send dual-purpose opening 46c from suction and flow out air channel switching device shifter 40.Send the room air that dual-purpose opening 46c sends from suction, flow to suck and send subsidiary conduit 23, after prefilter 24, send piping connection portion 23a, be discharged to outdoor by yard piping 15 from suction.
By such process, suck room air from main suction inlet 5, carry out dedusting with filter by suction 21b, realized being discharged to outdoor exhaust running from yard piping 15.Like this, in the transverse width dimension part that following two air channels is contained in air channel switching device shifter 40, thereby can reduce the transverse width dimension of air-supply arrangement 20; These two air channels are, send into opening 44e sends opening 44f to exhaust exhaust duct 45f from the suction opening 43a of the suction side of the pressure fan 33 of carrying room air to the suction air channel 45e of sucking-off opening 44d with from the exhaust of sending side of pressure fan 33.
At this moment, though suction chamber 31 also be communicated with by inlet channel 35 with the opening 46f that air intake filter 36, air intake filter are used,, since before this not have the connection opening, so except suction inlet 21a, can be from other partial-air admissions.At this moment, gathered in the air feed operation process dust under from outdoor air, removing though send piping connection portion 23a one side in the suction of prefilter 24, but, because the room air in exhaust when running flows through prefilter 24, send dust on piping connection portion 23a one side surface thereby can remove the suction that is collected at prefilter 24 effectively.
Therefore, air-supply arrangement 20 can make prefilter 24 clean voluntarily, thereby can reduce the number of times of cleaning prefilter 24 by carrying out air feed running and exhaust running repeatedly.In addition, in the process of air feed running, by automatically switching to the exhaust running of certain hour, the direction of the air stream of prefilter 24 is flow through in conversion, just can prevent that mesh from stopping up.
In addition, when exhaust is turned round,, reduced the flowing resistance when exhaust is turned round, can increase the amount of the room air of discharging, can carry out the exhaust running effectively because the room air of discharging does not pass through air intake filter 36.
More than, though air feed running and exhaust running are illustrated, in addition, by adding an indoor opening, the suction that makes one of them be exclusively used in room air, another is exclusively used in sends, just can carry out following said cycle operation, expand to colourful purposes.
Then, mainly with reference to Figure 12, Figure 18, the details when cycle operation is described.
During cycle operation, as Figure 12 and shown in Figure 180, drive 41 rotations of air channel switch piece by drive unit 47, make respectively and suck dedicated openings 46a and circulation openings 43c, circulation sucking-off opening 44a and sucking-off dedicated openings 46d send into dedicated openings 46e and circulation and send into opening 44d and circulation and send opening 43a and send dedicated openings 46b and be on the position that is communicated with.
So, suction chamber 31 just is communicated with following each several part: sucking-off dedicated openings 46d, circulation sucking-off opening 44a, circulation suck air channel 45c, circulation openings 43c, suck dedicated openings 46a, suck subsidiary conduit 21, filter by suction 21b, suction inlet 21a.On the other hand, sending chamber 32 is communicated with following each several part: send into dedicated openings 46e, circulation and send into that opening 44d, circulation send air channel 45e, circulation is sent opening 43a, sends dedicated openings 46b, sends subsidiary conduit 22, sent piping connection portion 22a.
Under such state, by pressure fan 33 rotations that make air-supply arrangement 20, room air just sucks from main suction inlet 5, enters the air-supply arrangement 20 from the suction inlet 21a at indoor set 1 inside opening, by being arranged on the filter by suction 21b that sucks in the subsidiary conduit 21, carry out dedusting.
Room air after the dedusting, enter the air channel switching device shifter 40 from connecting the suction dedicated openings 46a that sucks subsidiary conduit 21, suction opening 43c by air channel switch piece 41, flow through circulation and suck air channel 45c, by the circulation sucking-off opening 44a of air channel switch piece 41, flow out air channel switching device shifter 40 from sucking-off dedicated openings 46d.Room air after the sucking-off dedicated openings 46d sucking-off enters in the suction chamber 31, is inhaled in the pressure fan 33 by the import ring 31b that is arranged on the dividing plate 31a, and by after pressure fan 33 pressurizations, buries to pass out to and send in the chamber 32.
The outdoor air of sending out enters the air channel switching device shifter 40 from sending into dedicated openings 46e once more, send into opening 44d by the circulation of air channel switch piece 41, flow through circulation and send air channel 45e, send opening 43a by the circulation of air channel switch piece 41 again, flow out air channel switching device shifter 40 from sending dedicated openings 46b.Flowed out the outdoor air of air channel switching device shifter 40, flow through and be connected the subsidiary conduit of sending on the dedicated openings 46b 22 sent and arrive and send piping connection portion 22a, be connected after the air feed of sending on the piping connection portion 22a sends pipeline 12 flowing through, send mouth 13 from air feed, pass out to indoor as circulating air.
By such process, suck room air from main suction inlet 5, carry out dedusting with filter by suction 21b, realized sending mouthful 13 cycle operation of sending from air feed.Like this, in the transverse width dimension part that following two air channels is contained in air channel switching device shifter 40, just can reduce the size of the transverse width of air-supply arrangement 20; These two air channels are, circulation from the circulation openings 43c of the suction side of the pressure fan 33 of carrying room air to circulation sucking-off opening 44a sucks air channel 45c and sends into the circulation that opening 44d sends opening 43a to circulation from the circulation of sending side of pressure fan 33 and send air channel 45e.
At this moment, though opening 44e, exhaust duct 45f are sent in opening 46f, exhaust that suction chamber 31 is used by inlet channel 35 and air intake filter 36, air intake filter, exhaust is sent opening 44f and all is communicated with, but, owing to there is not the opening of connection before this, so except suction inlet 21a, can be from other partial-air admissions.And, be docked at and send on the piping connection portion 22a because air feed is sent pipeline 12, thereby, from send air that piping connection portion 22a sends just former state all enter air feed and send in the pipeline 12.
Though in above explanation is the situation of having only a suction subsidiary conduit 21, sending subsidiary conduit 22, but also for example can make, some suction subsidiary conduits 21 are set respectively, send subsidiary conduit 22, any one suction inlet from several suction inlets of indoor set 1 sucks, or send the mouth any one from several and send and mouthful send, make ventilatory have the structure of close grain shape.In addition, in the present embodiment, though the outer circle wall 43 of rotor 45 is made cylindrical shape, by on each position of rotation of air channel switch piece to and inner surface of outer cover between sealing work hard, also can make polygonal to it, also can play same effect.
In addition, because pressure fan 33 is to the fixed-direction rotation, the shape of import ring 31b and suction chamber 31 and the shape of sending chamber 32 can adopt the rational shape that adapts with pressure fan 33, thereby can obtain air-supply efficient height, the air-supply arrangement 20 that running noise is low.Further, the pressure fan motor 34 that drives pressure fan 33 is arranged in the recess that is arranged on the pressure fan 33, constituted the very thin wind pushing mechanism of width dimensions, air intake filter 36 is arranged in the bottom of pressure fan part 50, attenuate the width dimensions of air-supply arrangement 20, so, needn't increase the width dimensions of indoor set 1, just can be contained in air-supply arrangement 20 in the indoor set 1.
As mentioned above, according to present embodiment, air-supply arrangement 20 of the present invention has the pressure fan part 50 of carrying air and switches the air channel in the outdoor air supply chamber and room air is discharged to the air channel switching device shifter 40 in outdoor air channel.Pressure fan part 50 wherein has: from axial suction air and pass out to the centrifugal blower 33 of circumferencial direction; Be communicated with the suction chamber of doing greatlyyer 31 than this suction inlet with the suction inlet of pressure fan 33; Pressure fan 33 send that side forms send chamber 32.Air channel switching device shifter 40 wherein has: the shell 46 that a plurality of openings are arranged; Be arranged in the shell 46, can rotate, and the air channel switch piece 41 that inside is separated into the dividing plate in some air channels is arranged; Drive 41 rotations of air channel switch piece, with the drive unit that is communicated with 47 between a plurality of openings of many air channels of switching air channel switch piece 41 and shell 46.Because air channel switching device shifter 47 overlaps on the suction chamber 31 of pressure fan part 50 abreast, so it is simple in structure, can realize miniaturization, when can switch, can improve its reliability to air feed and exhaust.
