Description
The present invention relates to have the air-conditioner of the inverted V-shaped indoor heat converter of being formed by front side heat exchanger and rear side heat exchanger in the indoor set body interior.
Air-conditioner in the past tie up to the front and last the face machine have respectively suction inlet body interior, hold the air-conditioner that forms the inverted V-shaped indoor heat converter by front side heat exchanger and rear side heat exchanger.In this air-conditioner, be set to assemble drain pan respectively from the sluicing of each heat exchanger generation in the bottom of front side heat exchanger and rear side heat exchanger, in addition, for dwindling the size up and down of indoor set body, pressure fan is configured between front side heat exchanger and rear side heat exchanger, is covered by these heat exchangers making it.
Yet, owing to make compact conformation, and, make air velocity become big through heat exchange by the rear side heat exchanger with the close rear side heat exchanger arrangement of pressure fan.Therefore, make the sluicing that produces at the rear side heat exchanger flow to the air-supply pusher side, sluice when refrigeration etc. more occasion takes place, this sluicing does not flow to the drain pan that is arranged on rear side heat exchanger bottom, and from the rear side heat exchange of flowing through midway just to the air-supply pusher side drip, disperse in the air conditioning chamber.
Therefore, the object of the invention is to provide the air-conditioner that drips to the air-supply pusher side that can prevent from really to sluice from the rear side heat exchanger of flowing through midway.
The present invention in order to achieve the above object, for its body front and above form suction inlet respectively, in body, hold with forming the indoor heat converter of inverted V-shaped, simultaneously pressure fan by these front side heat exchangers and the covering of rear side heat exchanger is set in the face of the front side heat exchanger of above-mentioned each suction inlet and rear side heat exchanger respectively, and the air-conditioner of drain pan is set, the downwind side shutter that it is characterized in that between above-mentioned rear side heat exchanger and pressure fan, setting is positioned at the rear side heat exchanger respectively in the bottom of above-mentioned front side heat exchanger and rear side heat exchanger.
Adopt said structure, make the suction inlet above body stopped by shutter through the part that the rear side heat exchanger flows to pressure fan through heat exchange air.Specifically because shutter is arranged on the downwind side of rear side heat exchanger, promptly be configured in the rear side heat exchanger near the highest part of the wind speed of pressure fan.Therefore, the wind speed of this part that original wind speed has to uprise is reduced because of shutter,, flow to the air-supply pusher side can not resembling originally again, and normally flow to the drain pan side downwards in the sluicing that the rear side heat exchanger produces.
In addition, also can with the bottom of above-mentioned shutter in an overlapping shape be arranged on the inboard of the drain pan of rear side heat exchanger.In view of the above, even the sluicing of rear side heat exchanger is dripped downwards for the moment to the air-supply pusher side, the sluicing of dripping is stopped by above-mentioned shutter, is directed to the drain pan of rear side heat exchanger through shutter.
In addition, also can between the bottom of above-mentioned shutter and drain pan inboard, form the gap.In view of the above, owing to the heat exchange air through rear side heat exchanger lower end flows to the air-supply pusher side by above-mentioned gap, the mobile plate that is not blocked of air stops fully, thereby the characteristic of avoiding blowing descends.In addition, consider because of the cooling of rear side heat exchanger to shutter can sluice on the face of the air-supply pusher side of shutter in generation, but owing to be formed with the gap between shutter bottom and drain pan inboard, this sluicing is drawn towards drain pan and reclaims.
In addition, also above-mentioned shutter can be arranged to sheltering from from the roughly middle downside of rear side heat exchanger.With shutter the rear side heat exchanger is all sheltered from just nonsensically, in addition,, top-down sluicing is dripped from the pars intermedia more than the change to a certain degree as sluicing following place.Therefore, only downside is covered for good.
In addition, also can make the coiling beginning portion of above-mentioned shutter double as pressure fan, like this,, the coiling beginning portion of pressure fan be moved to the suction side, make and discharge the expansion of territory, lateral areas because of shutter.Like this, discharge the expansion of territory, lateral areas, suction side and the blast of discharging side are more tended to balance, make original incidental surge phenomenon (suction side and the reverse phenomenon of discharging side) disappearance, when improving the air-supply characteristic, air-supply sound is reduced by making.
In addition, also can with the heat-exchange fan of the not aspectant rear side heat exchanger of above-mentioned shutter part on form (cutting forms) slit.Like this, can make the sluicing that does not produce be stopped, be drawn towards the part that downside has shutter along the slit by above-mentioned slit in the face of the part of shutter at the rear side heat exchanger.Therefore, can prevent not the dripping to the air-supply pusher side that sluice downwards from the rear side interchanger in the face of the part of shutter.
In addition, the roughly pars intermedia of above-mentioned shutter vertically can be formed convex along it.Like this, the intensity of shutter can be improved, the installation strength between heat exchanger and shutter can be improved simultaneously.
In addition, can form stator, make this stator by rear side heat exchanger end plate and the clamping of pressure fan bearing block at vertical both ends of described shutter.Thus, can shutter is fixing reliably.

Below, with reference to accompanying drawing one embodiment of the invention is described.
Fig. 1 is the sectional view of expression air conditioner room unit body 1.As shown in the figure, this indoor set body 1 is made up of the back plate body 2 that forms back part, the grid 4 that forms facial front panel 3 and form face portion.Form upside suction inlet 5 on the above-mentioned front panel 3, sucking formation front side suction inlet 6 on the grid 4.
Hold the indoor heat converter 7 that forms inverted V-shaped in the inside of such indoor set body 1.This heat exchanger 7 has in the face of the front side heat exchanger 8 of front side suction inlet 4 with in the face of the rear side heat exchanger 9 of upside suction inlet 5, with the top of front side heat exchanger 8 and rear side heat exchanger 9 in accordance with regulations angle connect into the inverted V-shaped shape.In addition, secondary unit 10, each heat exchanger 8,9,10 being set above rear side heat exchanger 9 is made of heat-exchange fan 11 that separates predetermined distance configuration and the refrigerant piping 12 that passes these blower fans 11 respectively.
Dispose drain pan 13,14 respectively in the bottom of front side heat exchanger 8 and the bottom of rear side heat exchange 9, the pressure fan 15 that configuration covers with this two heat- exchanger 8,9 between front side heat exchanger 8 and rear side heat exchanger 9.Adopt this structure, by driving pressure fan 15, room air is inhaled into through front side suction inlet 6 and upside suction inlet 5, is blown to indoor by front side heat exchanger 8 and rear side heat exchanger 9 and ventilating duct 16 from outlet 17 again.At that time, the sluicing that takes place at each heat exchanger 8,9 is collected in the drain pan 13,14 respectively.In addition, at outlet 17 transom window 18 and left and right sides transom window up and down are set.
The characteristics of present embodiment are at rear side heat exchanger 9 and 15 in pressure fan, downwind side (rear side heat exchanger 9 is near the part of the pressure fan 15) shutter 20 that is positioned at rear side heat exchanger 9 are set.As shown in Figure 4, shutter 20 has the length length about equally with the horizontal direction of rear side heat exchanger 9, be configured to from rear side heat exchanger 9 roughly in the middle of downside is blocked.The roughly pars intermedia 21 of shutter 20 is formed the convex protruded along its longitudinally, is self intensity and the installation strength that improves shutter 20 for reaching.
As Fig. 2, shown in Figure 3, utilize shutter 20 to be installed on the rear side heat exchanger 9 at the installation sheet 22 that is provided with on the one side.As shown in Figure 4, with installation sheet 22 along shutter 20 vertically by separating the predetermined distance setting, have the engaging claw 23 that engages with the refrigerant piping 11 of rear side heat exchanger 9 on it.Engaging claw 23 has the arc sections 24 that refrigerant piping 11 can be embedded, and forms two one group, refrigerant piping 11 is sandwiched its inboard or the outside.
As shown in Figure 4, on vertical both ends of shutter 20, form stator 25, so that these stators 25 are by the end plate of rear side heat exchanger 9 (not shown) with putting bearing base (not shown) clamping of the pressure fan 15 of this end plate on it.By installation fixing with this stator 25 and with described installation sheet 22, installation sheet 22 because of coming off from refrigerant piping 11, the vibration grade is also taken into account, and can be with shutter 20 secure fixation.
As Fig. 2, shown in Figure 3, have the flat part 20a with the 9 parallel formation of rear side heat exchanger in the bottom of shutter 20, have rake 20b open above rear side heat exchanger 9 on top.The oblique 20b of portion is configured to from the roughly middle of rear side heat exchanger 9 downside be covered, assembles the sluicing of dripping from rear side heat exchanger 9.Flat part 20a is configured to inboard overlapping with the drain pan 14 of rear side heat exchanger 9, with the oblique 20b of portion the sluicing guiding drain pan of assembling 14.
As shown in Figure 2, between the inboard of flat part 20a and drain pan 14, form gap 26.In addition, at rear side heat exchanger 9 and 27 of the plates in back heat-insulating material 28 is set.Horizontal direction along rear side heat exchanger 9 is provided with heat-insulating material 28 at interval, becomes the lower end that makes rear side heat exchanger 9 and 27 of the plates in back and does not produce air and flow.Make the air of back, edge plate 27 1 side flow flow into rear side heat exchanger 9 reliably with this structure, carry out there flowing to pressure fan 15 1 sides by the flat part 20a of shutter 20 and the gap 26 between drain pan 14 inboards after the heat exchange.
In addition, as shown in Figure 5, the coiling portion that begins of shutter 20 double as pressure fans 15.The roughly pars intermedia 21 that is used in shutter 20 exactly forms convexs, makes near the part of pressure fan 15, makes the zone of the discharge side 29 of pressure fan 15 only enlarge the θ angle to the suction side exactly.In addition, as shown in Figure 2, rear side heat exchanger 9 not in the face of the heat-exchange fan 12 of the part 9a of shutter 20 on form slit 31.By with one one of heat-exchange fan 12 along its vertically cutting form slit 31.In addition, in Fig. 2, in drawing of rear side heat exchanger 9 in the face of on the part 9b of shutter 20 slit being set also, yet, not not establish yet.
Now the effect by this example that said structure constituted is described.
Making above body 1 suction inlet 5 flow to pressure fan 15 by rear side heat exchanger 9 slows down because of stopping of shutter 20 through the part of air of heat exchange.Specifically, because shutter 20 is configured in the downwind side of rear side heat exchanger 9, promptly becomes it is configured in the highest part of wind speed near the rear side heat exchange 9 of pressure fan 15.Therefore, the wind speed of this part that original wind speed has to uprise is slowed down because of shutter 20, do not flow to pressure fan 15 1 sides the sluicing that produces can not resemble originally on rear side heat exchanger 9, and normally flow to drain pan 14 downwards.
In addition, owing to make drain pan 14 inboard overlapping of the lower flat board 20a of shutter 20 and rear side heat exchanger 9, even temporarily drip to pressure fan 15 1 sides in the sluicing that rear side heat exchanger 9 produces, the sluicing of dripping is blocked that the oblique 20b of portion of plate 20 blocks and the flat part 20a that flows through is directed to heat exchanger 9 and drain pan 14.
In addition since between the inboard of the flat part 20a of shutter 20 bottoms and drain pan 14 formation gap 26, make the air that passes through from back plate 27 sides of rear side heat exchanger 9 by shutter 20 flat part 20a and the gap 26 of 14 of drain pans flow to pressure fan 15 sides.Like this, because air flows not because of shutter 20 is obstructed fully, the characteristic of just avoiding blowing descends.
In addition, considering also that shutter 20 produces on the face of pressure fan 15 1 sides of shutter 20 because of rear side heat exchanger 9 is cooled sluices, yet, this sluice because of in the inboard of the flat part 20a of shutter 20 bottoms and drain pan 14 to the above-mentioned gap 26 of formation, and the drain pan 14 that leads through the surface of shutter 20 is recovered again.
In addition, shutter 20 is configured to be from the roughly middle reason that downside is blocked of rear side heat exchanger 9: a direction, block on ventilating whole rear side heat exchanger 9 meaningless with shutter 20, on the other hand as the following place that sluices, top-down sluicing, be from increasing to following of pars intermedia to a certain degree.Therefore, shutter 20 is arranged on from rear side heat exchanger 9 roughly in the middle of downside.
In addition, by shutter 20 is set, with the coiling portion that begins of pressure fan 15 to only mobile θ angle, suction side 30, the zone of discharging side 29 is enlarged.Like this, by enlarging the zone of discharging side 29, suction side 30 and the blast of discharging side 29 are more tended to balance, original incidental surge phenomenon (suction side 30 and the reversing phenomenon of discharging side 29) is disappeared, when improving the air-supply characteristic, air draft sound is reduced.
In addition, since with the heat-exchange fan 12 of the not aspectant rear side heat exchanger 9 part 9a of shutter 20 on form the slit (cutting forms 31, make rear side heat exchanger 9 with the not aspectant part 9a of shutter 20 on the sluicing that produces by 31 hurdles, slit cut, along the slit shutter 20 of 31 guiding downsides part 9b, on shutter 20, drip.Therefore, can prevent that the part 9a that sluices from the not aspectant heat exchanger 9 of shutter 20 from dripping to pressure fan 15 sides.
In sum, adopt air-conditioner of the present invention, can reliably prevent the dripping to pressure fan 15 sides that sluice midway from the rear side heat exchange of flowing through.
