Implement optimal mode of the present invention

Referring to accompanying drawing embodiments of the invention are described.

One outdoor unit of the first embodiment of the present invention is at first described referring to Fig. 1.This outdoor unit has a main body or housing 1.See that from above this housing is rectangular.This outdoor unit comprises a heat exchanger 2, a vertical compression machine 3 and a fan unit 4.Heat exchanger 2, vertical compression machine 3 and fan 4 are arranged in the housing 1.(compressor 3 has a compressing mechanism, and it has a vertical axis, and therefore, height dimension is greater than width dimensions.)

Housing 1 has an axis 5.Its left and right sides two halves are symmetrical in axis 5.Heat exchanger 2, vertical compression machine 3 and fan unit 4 are arranged along the axis 5 of housing 1.The axis of heat exchanger 2, vertical compression machine 3 and fan unit 4 all aligns with the axis 5 of housing 1 basically.Therefore, the left and right sides two halves separately of these parts all are symmetrical in the axis 5 of housing 1.

Fig. 1 is a plane of this outdoor unit.As shown in Figure 1, housing 1 has an antetheca 1a, a rear wall 1b and two side 1c.When this outdoor unit was installed, rear wall 1b separated a predetermined distance with for example outer wall of a shell.Have the hole (not shown) on antetheca 1a, rear wall 1b and the sidewall 1c.When fan unit turned round, air sucked housing 1 by the hole that processes on rear wall 1b and the sidewall 1c, and sends from housing 1 by the hole that processes on the antetheca 1a.

Heat exchanger 2, vertical compression machine 3 and fan unit 4 distribute according to described order from the upstream side of the air-flow that fan unit 4 is produced.Like this, the effect of ingate is played in the hole relative with heat exchanger 2 of making on rear wall 1b and sidewall 1c, and the hole of the relative fan unit of making on antetheca 1a 4 is as outlet opening.

Heat exchanger 2 is a U-shaped substantially, and it comprises a long part 2a and two short part 2b.Long part 2a is relative with the rear wall 1b of housing, and short part 2b is relative with two side 1c respectively.In other words, long part 2a is between rear wall 1a and vertical compression machine 3, and short part 2b is between fan unit 4 and sidewall 1c.(that is, heat exchanger) pipeline (not shown, i.e. inlet ductwork and export pipeline) is connected with vertical compression machine 3 to be connected in the kind of refrigeration cycle parts of heat exchanger 2 and indoor unit.These pipelines are arranged in the space that is limited by heat exchanger 2, vertical compression machine 3 and fan unit 4.In housing 1, there is not unnecessary space.In other words, obtainable space all has been utilized in housing 1.

Fan unit 4 comprises a fan electromotor 4a and blade fan 4b (back becomes " fan ").Fan 4b is fixed on the axle of fan electromotor 4a.Fan 4b is positioned at the air-flow upstream, and fan electromotor 4a is arranged on its downstream.Fan 4b is between the short part 2b of heat exchanger 2.Therefore, a short part 2b is between a fan 4b and a sidewall 1c, and another short part 2b is between fan 4b and another sidewall 1c.

In the running, vertical compression machine 3 is driven, compressed refrigerant.The cold-producing medium that is compressed circulates in the refrigerating circuit that comprises heat exchanger 2.Like this, the outdoor unit running is carried out air conditioning to the room that indoor unit is housed.

Be driven at compressor 3, cold-producing medium is circulation time in refrigerating circuit, and fan unit 4 also is driven, and by the discharge orifice of making on rear wall 1b and sidewall 1c of going into air is sucked housing 1.Air flows into housing 1, passes heat exchanger 2.Heat exchanger 2 carries out heat exchange between air and cold-producing medium.Part air contact compressor 3 cools off compressor.Then, fan unit 4 is discharged housing 1 by the flow-out hole made from air on antetheca 1a.

In said structure,, just can determine the suitable width of housing 1 as long as determined the diameter of the fan 4b of fan unit 4.Compressor 3 still is the width that pipeline all can not limit housing 1.So just can reduce the width of housing 1, reduce the installing space of outdoor unit.

In addition, housing 1 sees it is rectangle from above, and is very simple on the structure.

Because heat exchanger 2, vertical compression machine 3 and fan unit 4 are provided with along the axis 5 of housing 1, their axis all aligns with axis 5 basically, so their left side and right-hand parts separately are symmetrical in axis 5.Therefore, the weight balancing of this outdoor unit is fine, can keep stable well when a place moves to another place.

And, because heat exchanger 2 is positioned at the upstream extremity of air-flow, so air one just contacts heat exchanger 2 immediately through mouthful suction housing 1 that becomes a mandarin.This means that heat exchanger 2 works efficiently.

One outdoor unit of the second embodiment of the present invention is described below with reference to Fig. 2.Except the shape of housing 1A and heat exchanger 2A, the same with first embodiment at second embodiment aspect other.As in first embodiment, heat exchanger 2A, vertical compression machine 3 and fan unit 4 are provided with along the axis 5 of housing 1A, and the axis of these parts and axis 5 align.And air flows with the direction identical with first embodiment in housing 1A, all concerns identical at go into discharge orifice and the flow-out hole made on the wall of housing 1A with position in first embodiment.Therefore, from these architectural features, second embodiment has obtained the advantage identical with first embodiment.

The rear wall of housing 1A is crooked, comprises flat middle body 1d and the sidepiece 1e that tilts.Middle body 1d is parallel to antetheca 1a.Left and right sides sidewall 1e tilts towards sidewall 1c respectively.Though housing 1A is identical with the degree of depth of housing 1 shown in Figure 1, its rear wall has a left side and the right half of inclination.

Heat exchanger 2A is essentially U-shaped, but its long part 2c is an arc, has a predetermined radius of curvature.Long part 2c roughly extends along the middle body 1d and the sidepiece 1e of the rear wall of housing 1A.

Because the rear wall of housing 1A is with aforesaid mode bending, so when outdoor unit is mounted to middle body 1d when contacting with the outer wall 6 of shell, the discharge orifice of making on sidepiece 1e of going into is not related to and closes.Therefore, air not only can be by the discharge orifice of making on the 1c of the two side of housing 1A of going into, and can suck housing 1A swimmingly by the discharge orifice of making on sidepiece 1e of going into.

In other words, outdoor unit shown in Figure 2 can be mounted to the outer wall 6 of shell and contact.This means the reducing of installing space of outdoor unit.In addition, it is dark like that housing 1A seems not resemble its reality, because its rear wall has the sidepiece 1e to sidewall 1c inclination from flat middle body 1d.

Be driven and cold-producing medium circulation time in refrigerating circuit at compressor 22, fan unit 24 also is driven, by going into discharge orifice with air suction housing 21 on the rear wall 21b.Air flows in housing 21.Portion of air contacts with vertical compression machine 22, cools off this compressor 22, flows through heat exchanger 23 then.Remaining air directly flows through heat exchanger 23.Therefore, heat exchanger 23 carries out heat exchange between air and cold-producing medium.Then, fan unit 24 is discharged air by the flow-out hole on the antetheca 21a from housing 21.

Among superincumbent the 11 embodiment,, just can determine the suitable diameter of housing 21 as long as the diameter of the fan 24b of fan unit 24 one is definite. be the width that compressor 22 or the pipeline that links with it all can not limit housing 21.Therefore, the width of housing 21 can reduce, thereby reduces the installing space of outdoor unit.In addition, housing 21 is seen as rectangle from above, and structure is also very simple.

Vertical compression machine 22, heat exchanger 23 and fan unit 24 are arranged on the axis of housing 1, and their axis aligns with axis 25 basically.The left and right sides halves separately of these parts is symmetrical in axis 25.As a result, get finely according to the weight balancing of the outdoor unit of the 11 embodiment, it can kept stable when one moves to another place.

And portion of air is contacting with vertical compression machine 22 immediately after discharge orifice is introduced housing 21 by going into, because compressor 22 is positioned at the upstream extremity of air-flow.This means that vertical compression machine 22 has played the effect that improves cooling effectiveness.

Vertical compression machine 22 is positioned at the upstream of fan unit 24, and its center O is on the axis of fan 24b, and the axis 25 of this axis and housing 21 aligns.Air is mobile with lower speed in the zone of the axis of fan 24b one.Therefore, fan 24b is flowing air with lower speed in the zone of axis Q.So if exist any barrier in this zone, it can not play drag effect to air-flow, also can not weaken the air blast efficient of fan 24b greatly.

Figure 12 illustrates the outdoor unit according to an air-conditioner of the 12nd embodiment of the present invention.Those with the 11 embodiment (Figure 11) in the identical numbering of parts in Figure 12 as before, no longer go through.Shown in Figure 12 as the plane, vertical compression machine 22 is provided on a jiao of housing 21.In other words, the center O of compressor 22 is positioned at outside the axis 25 of housing 21 or near a side of heat exchanger 3.

This outdoor unit fully on weight imbalance but airflow direction do not change.Therefore, the heat exchange efficiency of heat exchanger is improved.In addition, can reduce the width of housing 21, thereby reduce the installing space of outdoor unit, because compressor 22 still is the width that connected pipeline can not limit housing 21.And housing 21 is seen as rectangle from above, and structure is very simple.

Figure 13 illustrates the outdoor unit according to an air-conditioner of the 13rd embodiment of the present invention.As shown in figure 13, a vertical compression machine 22, a heat exchanger 23A and a fan unit 24 be according to said sequence, is provided in the housing 21 of outdoor unit along the axis 25 of housing 21.Or rather, the center of compressor 22, heat exchanger 23A and fan unit 24 is all on the axis 25 of housing 21.

Housing 21A sees from above and is roughly rectangle, but form a projection 26 on rear wall 21b.Projection 26 is integrally formed with housing 21A, and stretches out on the axis 25 of housing 21A.

The degree of depth of housing 21A, that is, the degree of depth of the housing 21 among the distance between the antetheca 21a of housing 21A and projection 26 the far-end and 11 and 12 embodiment (Figure 11 and 12) is identical.Projection 26 has a curved surface, and this curved surface has a predetermined radius of curvature.The two ends of projection 26 are roughly straight, and favour the rear wall 21b of housing 21A.Vertical compression machine 22 is arranged in the projection 26.That is, compressor 22 is arranged in the back of the heat exchanger 23A that is provided at housing 21A and extends along the inner surface of rear wall 21b.

Heat exchanger 23A sees from above and is roughly U-shaped.Its long part 23a is relative with the rear wall 21b of housing 21A, and its left side is relative with the sidewall 21c of housing 21A with right two short part 23b.In other words, long part 23a is provided in the space that rear wall 21b, vertical compression machine 22 and fan unit 24 by housing 21A limited, and short part 23b is arranged in the space that is limited by sidewall 21c and fan unit 24.

On the wall of antetheca 21a, the rear wall 21b of housing 21A, sidewall 21c and projection 26, make the through hole (not shown).The hole of making on antetheca 21a is as flow-out hole.Be used as into discharge orifice on wall 21b and the 21c and the hole of making on the wall of projection 26.Vertical compression machine 22, heat exchanger 23A and fan unit 24 are set in sequence in the housing 21A with described from the upstream of air-flow.

The 13 embodiment gets into smooth identical with the first to the 12 embodiment.The width of housing 21A descends, thereby reduces the installing space of outdoor unit.Each

parts

22,23A and 24 left and right sides halves all are symmetrical in axis 25.Therefore, fine according to the weight balancing of the outdoor unit of the 13 embodiment, in the local time that moving to another, a place can keep stable.

And then, owing to vertical compression machine 22 is arranged in the projection 26, and go into discharge orifice on the wall of projection 26, so, a big space provided round projection 26.A large amount of air can suck housing 21A from this big space.

The air capacity of contact vertical compression machine 22 increases, thereby has strengthened cooling effectiveness.

The air capacity that is applied on the heat exchanger 23A has also increased, and heat exchanger 23A is seen as U-shaped from above.This helps the raising of heat exchanger effectiveness.

Figure 14 illustrates the outdoor unit according to an air-conditioner of the 14th embodiment of the present invention.Be provided at except projection 26 on the right-hand part of rear wall 21b of housing 21B, rather than beyond on the axis 25 of housing 21B, the 14 embodiment and the 13 embodiment (Figure 13) are just the same.(projection 26 also can be arranged on the left side of rear wall 21b).As the 13 embodiment, a vertical compression machine 22 is provided on the projection 26.

Because projection 26 is provided on the right-hand part of rear wall 21b, the weight of this outdoor unit is inevitable uneven.Yet the direction of air-flow can not change.Therefore, heat exchanger effectiveness is improved.And then the width of housing 21B can descend, thereby reduces the installing space of outdoor unit, because compressor 22 still is the width that connected pipeline can not limit housing 21B.So just the installing space with outdoor unit reduces, and housing 21B is structurally very simple.

And then, when outdoor unit is installed to such an extent that projection 26 is determined according to the outer wall of a shell, provide a big space around protruding 26.A large amount of air can suck projection 26 from this big space, also suck housing 21B.Because vertical compression machine 22 and heat exchanger 23A are separately positioned in projection 26 and the housing 21B, so as in the 13 embodiment, cooling effectiveness and heat exchanger effectiveness all are improved.

Figure 15 A and 15B illustrate an outdoor unit of the 15th embodiment of the present invention.Except the shape of housing 21C and heat exchanger 23B, the 15 embodiment and the 13 embodiment shown in Figure 13 are identical.

Vertical compression machine 22, heat exchanger 23B and fan unit 24 are arranged on the same axis, that is, on the axis 25 of housing 21C, this is identical with the 13 embodiment.In other words, the axis of the core of compressor 22, heat exchanger 23B and fan unit 24 and axis 25 align.Fan unit 24 sucks housing 21C with air along the direction identical with the 13 embodiment, and discharges in it.Identical among the position relation of going into discharge orifice and flow-out hole of on the wall of housing 21C, making and the 13 embodiment.Therefore, the 15 embodiment has obtained the advantage identical with the 13 embodiment.
