End plate T is connected and be fixed on the plate 4 of back by fastener or with screw, thereby fix the position of heat exchanger part 5a to 5c.

Back again referring to Fig. 2 to 4, a preceding rhone 6 is set below preceding heat exchanger part 5a.And after being provided with one below the heat exchanger part 5b of back rhone 7.Rhone 6 and 7 and the back plate 4 make integral body.

The one indoor hair-dryer with cross flow fan 8 is set between preceding heat exchanger part 5a and back heat exchanger part 5b.And between back plate 4 and preceding rhone 6 lower surfaces, form a ventilating duct 9.

Form air outlet 10 in header board 20 bottoms.In air outlet 10, pivotally supporting polylith airflow direction guide plate 11.Last air intake grill 3 has an air entry 3a.

On the other hand, on the upper front surface of preceding heat exchanger part 5a, air purifier 12 is set, so that air purifier 12 is provided with by ten fens approaching preceding heat exchanger part 5a of fixture K.

Therefore, the top of header board 20 is at its horizontal protrusion, to form protuberance 2a.In protuberance 2a, form the first air entry 15a, and below this protuberance, form the second air entry 15b.

Air purifier 12 comprises the electric cleaner 13 that the preceding heat exchanger part 5a of a vicinity is provided with; An odor removal filter 14 that is arranged in electric cleaner 13 sides; And casing 50 that is used for holding electric cleaner 13 and odor removal filter 14.

Electric cleaner 13 and odor removal filter 14 are provided with in parallel to each other, and integrally are contained among the casing 50.Electric cleaner 13 has a known structure that comprises dust collection filter and discharge portion.And dust collection filter and odor removal filter 14 are made removable open type so that clear up when needed.The discharge portion that is made of steel wire or spun gold also can break away from casing 50 when needed.

Air purifier 12 with said structure reaches forward on the preceding heat exchanger part 5a, and the width of air purifier 12 is identical with the width of preceding heat exchanger part 5a.

Figure 1A and 1B represent a kind ofly with fixture K air purifier 12 and indoor heat converter 5 to be connected to structure on the plate 4 of back.

Fixture K is made of a binding 21 and a plurality of hold-down screw 22a and 22c, and binding is the tabular component of a metal and makes by a for example crooked block plate; And hold-down screw is to fasten part.

Air purifier 12 integrally is connected with indoor heat converter 5 and is fixed on the binding 21 with hold-down screw 22a to 22c.And indoor heat converter 5 also is connected by binding 21 with air purifier 12 and is fastened on the plate 4 of back.

Should be noted that binding 21 is placed in indoor heat converter 5 tops.That is to say that binding 21 begins to be provided with from the preceding heat exchanger part 5a front surface top that constitutes indoor heat converter 5, and extend to upper lateral part behind the secondary heat exchanger part 5c by heat exchanger part 5b top, back.

Binding 21 is bent, so that be shaped along the end plate T that is arranged on each heat exchanger part 5a to 5c two ends.End plate T and the binding 21 usefulness hold-down screw 22a of preceding heat exchanger part 5a interconnect and fix.

Because the top of preceding heat exchanger part 5a recedes, hold-down screw 22a inserts from an acclivitous position.

Back plate 4 have one tiltedly to tilt to top 23.Be placed on the binding 21 on the end plate T, its sweep end 21a at secondary heat exchanger part 5c rear side is bent, so that this sweep end 21a can be placed on the upper surface on top 23.The sweep end 21a of binding 21 and back plate 4 usefulness hold-down screw 22b interconnect and fix.

Because top 23 is tiltedly to tilting, and the sweep end 21a of binding 21 is placed on the upper surface on top 23, and hold-down screw 22b is inserted into from the position that is inclined upwardly as hold-down screw 22a.

Because indoor heat converter 5 has preceding heat exchanger part 5a and back heat exchanger part 5b forms the such structure of a upset " V " shape, must form a space S at the rear portion of back heat exchanger part 5b.Space S can be used as a working space that inserts or take out at binding 21 and the hold-down screw 22b between top 23.

On the other hand, binding 21 ends of contiguous preceding heat exchanger part 5a are bent, so that contact and air purifier 12 integrally formed flange connectors 25.Hold-down screw 22c is used to the sweep end 21b of flange connector 25 and binding 21 is interconnected and fixes.

Flange connector 25 is upright according to the direction of vertical roughly.Certainly, the sweep end 21b of binding 21 that is set for contact flange connector 25 is also bent by vertical ground.Therefore, be used for connecting and fixedly connected the hold-down screw 22c of sweep end 21b of flange 25 and binding 21 and insert along the direction of cardinal principle level.

As mentioned above, air purifier 12 and indoor heat converter 5 are interconnected to integral body by the fixture K that comprises binding 21 and hold-down screw 22a to 22c.And air purifier 12 is connected by binding 21 with indoor heat converter 5 and is fixed on the plate 4 of back.

The form location of the bottom that should be noted that air purifier 12 closely contact with the end plate T of preceding heat exchanger part 5a, and by hold-down screw 22d connection be fixed on the end plate T.Because preceding heat exchanger part 5a has shape mentioned above, hold-down screw 22d inserts towards the direction of approximate horizontal.Consequently, be used for connecting with each hold-down screw 22d of fixed air clarifier 12 upper and lowers all level insert.

On the other hand, integrally form two claws 51 along its length at the other end place of air purifier 12, these two claws stretch out on casing 50 towards the preceding heat exchanger part 5a that is arranged on casing 50 rear portions.That is to say that claw 51 is being made facing to fixing some positions of the direction of insertion of binding 21 usefulness screws.Each claw 51 has a little elasticity, so that can insert and fix when an anterior position pushes a position between two vertical heat-exchange tube P at claw 51.

Introduce the operation of air regulator indoor set now with structure mentioned above.When the operation of the kind of refrigeration cycle of indoor heat converter 5 is performed and cross flow fan 8 when rotating, the air of the house interior that must be conditioned by preceding air intake grill 2 the first and second air entry 15a, 15b and on the air entry 3a of air intake grill 3 be inhaled into main body 1.

The air that imports by the first air entry 15a is introduced into air purifier 12.That is to say, make air carry out deodorizing by odor removal filter 14 by odor removal filter 14.On the other hand, make showy dust thin in the air by electric cleaner 13 charged so that be captured and accumulate in live part.Consequently, be introduced into the preceding heat exchanger part 5a that constitutes indoor heat converter 5 through the air that purifies, so that carry out heat exchange.

Directly imported preceding heat exchanger part 5a by the second air entry 15b inhaled air, thereby carried out heat exchange.And be imported into secondary heat exchanger part 5c and back heat exchanger part 5b, thereby carry out heat exchange by air entry 3a inhaled air.

The air that lives through heat exchange in heat exchanger part 5a to 5c is directed into ventilating duct 9 from cross flow fan 8, makes it then by air outlet 10, so that be blown out among the room that must be conditioned.The air that lives through heat exchange is along channel cycle mentioned above, so that be introduced into air purifier 12 and indoor heat converter 5.Therefore air can be cleaned and regulate as required.

Because both integrally are connected on the plate 4 of back the fixture K that comprises binding 21 and hold-down screw 22a to 22c indoor heat converter 5 and air purifier 12, can reduce the member of many original needs.And the appropriate intervals between indoor heat converter 5, air purifier 12 and back plate 4 can be held.

Because binding 21 is metallic plates, can obtain gratifying intensity.If the employing steel plate can also reduce the cost of this member.And can obtain gratifying durability and intensity.

Because binding 21 is arranged on indoor heat converter 5 tops, the discharge water that produces in indoor heat converter 5 can not arrive binding 21.Thereby can prevent from binding 21, to produce corrosion.

Hold-down screw 22c between binding 21 and air purifier 12 inserts along the direction of cardinal principle level.Therefore, even close on the wall portion surface that must be conditioned the room ceiling and cause top working space deficiency, also can be easily when keeping in repair take air purifier 12 away or the latter is connected on the main body 1 from main body 1 owing to indoor set is connected to.

The upper and lower of air purifier 12 is fixed on the preceding heat exchanger part 5a with hold-down screw 22d.Consequently, air purifier 12 is fixed on two positions, i.e. upper and lowers by screw.Therefore, air purifier 12 can be connected and fix securely.Because hold-

down screw

22c and 22d insert along the direction of cardinal principle level, can load onto or throw off air regulator 12 easily when keeping in repair.

The other end of air purifier 12 is provided with like this, a position before claw 51 can insert easily between the heat-exchange tube P of heat exchanger part 5a, thus be fixed.So, after the hold-down screw 22d that takes off fixed air clarifier 12 these ends, pull out casing 50 forward, just can make claw 51 leave heat-exchange tube P.Therefore, can carry out the overall pulling down of air purifier 12 very easily.

And, at the end plate T of preceding heat exchanger part 5a and the hold-down screw 22a between the binding 21, and the hold-down screw 22b both between top 23 and binding 21 of back plate 4 according to direction on being tilted to, that is to say that identical direction inserts.Therefore, when keeping in repair, can carry out installation or separation easily.

Indoor heat converter 5 is made upset " V " shape, and at back heat exchanger part 5b and back the space S between the plate 4 be used to be screwed binding 21 and back plate 4 to top 23.Therefore, when keeping in repair and so on work, can keep a big working space.Therefore space S can obtain utilizing effectively.

Except fixture K, the present invention also has following characteristics.

Refer back to Fig. 2, form the opening 30 that pipeline is used on each of header board 20 left and right ends, described left and right end is the turning between header board 20 sides and the bottom surface.Embed liner plate 31 at pipeline with one of admittance in the opening 30, thereby close pipeline opening 30.

Fig. 6 draws and embeds the detailed structure of liner plate 31.Embedding liner plate 31 usefulness makes with header board 20 identical materials.And the color that embeds liner plate 31 is also identical with header board 20 with thickness.Described embedding liner plate 31 is L-shaped.

On each surface, have the groove 32 that to pound out when needing, and a hook 33 stretches out on each surperficial leading end.In addition, also integrally make guide 34 in the both sides of hook 33.

Each hook 33 and guide 34 all are dismountable for pipeline tapping 30 ends of header board 20.Therefore, if desired, can from header board 20, take out and embed liner plate 31.

That is to say that according to the mounting condition of indoor set, subsidiary conduit and electric wire can any one part be pulled out from main body 1 left and right part.As an alternative, any one can be pulled out from any one lateral parts in subsidiary conduit or the electric wire, and other members can be pulled out from the another side part.

So, the left end and the right-hand member both of header board 20 embedding liner plate 31 is housed, in case need and can remove.Therefore, these pipelines can be opened with opening 30, thereby allow in right hand square tube road and line construction and left-hand pipeline and the line construction any one to pass through.

When having only subsidiary conduit or electric wire to be drawn out, the groove 32 usefulness abate methods that being utilized as embedding liner plate 31 provides are made an opening.Yet the embedding liner plate 31 that is connected with header board 20 still is retained.

As shown in Figure 7, can adopt a kind of structure to prevent because that the repulsive interaction of auxiliary piping H causes in the indoor assembly is loosening.

That is to say that the lower end of back plate 4 is to front curve, thereby formation arrives the ventilating duct 9 of air outlet 10.Back plate 4 is connected on the anchor plate 35, and described anchor plate 35 is connected on the room metope that must be conditioned in advance.Between anchor plate 35 and back plate 4 bottom rear sides, form a space S a.

From the subsidiary conduit H that indoor heat converter stretches out, a scupper hose D or a wire (drawing in the end) that the past rhone 6 stretches out are contained among the space S a in parallel to each other.

When carrying out the kind of refrigeration cycle operation, the outer surface cooling of subsidiary conduit H, so the easy frosting of this outer surface.Because scupper hose D is flow through in the low temperature discharge water, the outer surface of scupper hose D also can cool off and frosting easily.

If subsidiary conduit H contacts with back plate 4 with scupper hose D, because plate 4 can cool off after the heat conduction undesirablely.So packing into one between the plate 4 in subsidiary conduit H, scupper hose D and back is bonded in thermal insulation member 36 on plate 4 outer surfaces of back.

When subsidiary conduit H and scupper hose D are received within when being above described state among the space S a, subsidiary conduit H and scupper hose D are accommodated in little the unusually little space.Because subsidiary conduit H is a metal tube, and anchor plate 35 is connected and is fixed on the wall surface W in a room that must be conditioned, the bottom of plate 4 after the repulsive interaction of subsidiary conduit H focuses on.That is to say that the lower end of back plate 4 can be left and be the above anchor plate 35 of described state.That is to say, take place loosening.

Loosening for the lower end that prevents back plate 4, the lower end of anchor plate 35 not only bends forward but also bends backward according to an incline direction, thereby forms a support lug 37.

On the other hand, the lower end of back plate 4 extends back, and makes the space S a closure of admitting subsidiary conduit H and scupper hose D.The end of this extension is bent, to form a curved part 38 that closely contacts with support lug 37.

Curved part 38 and support lug 37 usefulness hold-down screws 22 interconnect and fix.Therefore, hold-down screw 22 is fixed to the lower end of back plate 4 on the lower end of anchor plate 35 reliably.So,, also can prevent the loosening of plate 4 lower ends, back even produce from the repulsive interaction that is contained in the subsidiary conduit H among the space S a.

Because hold-down screw 22 can cause presentation quality to worsen must being conditioned to expose in the room, stretch out front shield 20 lower ends, till the wall surface W in this room of this time end in contact, so that cover hold-down screw 22.
