Described fan main body 41 is tube-axial fans, is positioned at fan and is connected with motor 42 with the top of motor 42 and this fan.That is to say that described fan main body 41 is arranged in the up and down altitude range of electric and electronic components and parts unit 60.
Described horn-like parts 43 are installed on the casing 20, to cover the peripheral part of fan main body 41.Described horn-like parts 43 comprise guide part 43a cylindraceous and guard section 43b.This guard section 43b follows the upper end of this guide part 43a, enlarges gradually toward the outside towards the top.
Described horn-like parts 43 are installed in casing 20 so that the lower end of these horn-like parts 43 be the lower end of guide part 43a at described fan with between the upper and lower side of motor 42.That is to say that described fan is arranged in the central part of guide part 43a with motor 42.
As shown in Figure 6, described outdoor fan 40 is arranged in this fan center A from the center of the overlooking B of described casing 20 towards away from the residing position after the direction skew of the opening 3a on the described outdoor heat converter 30.
Particularly, described fan center A connects the center FC (with reference to Fig. 4) of axle of fan main body 41 of two outdoor fans 40 and the center of the line that forms in top view.Described casing 20 is to connect four angles of this casing 20 and cornerwise intersection point of forming at the center B of overlooking.In the present embodiment, this fan center A is displaced to the rear side of the center of the overlooking B of casing 20.
Further specifically, as shown in Figure 1, the position of described outdoor fan 40 is displaced to the trailing flank direction of the traverse SL that passes through its left and right directions of overlooking center B of described casing 20, is displaced to space one side of being surrounded by outdoor heat converter 30 in top view.That is to say that as shown in Figure 4, outdoor fan 40 is supported by casing 20, so that in the side view of described outdoor unit 10, the axle center FC of described fan main body 41 is displaced to the rear side that it overlooks the vertical centre BC of center B that passes through of described casing 20.Described outdoor fan 40 is established near outdoor heat converter 30.Because the position of outdoor fan 40 is displaced to the rear, so described electric and electronic components and parts unit 60 just is disposed between the horn-like parts 43 of the leading flank of described casing 20 and described outdoor fan 40.Described air outlet 26 forms the rear side that is positioned at central authorities.
-running action-
Next, the working condition of described outdoor unit 10 explained.
At first, drive after described compressing mechanism 50 and the drive chamber's external fan 40, outdoor air is just sucked the lower space 2a of casing 20 from air entry 25.Because outdoor air passes through outdoor heat converter 30 in the way that flows into lower space 2a, so outdoor air can carry out heat exchange with cold-producing medium in outdoor heat converter 30.Outdoor air in the described lower space 2a flows into upper space 2b, and the fan main body 41 by outdoor fan 40 blows to the outside from air outlet 26.
On the other hand, for example condensation in outdoor heat converter 30 of compressed cold-producing medium in described compressing mechanism 50, flow into afterwards indoor unit, in indoor heat converter, return compressing mechanism 50 after the evaporation, repeat this refrigerant circulation to carry out cooling operation etc.
The effect of the-the first embodiment-
As mentioned above, in this first embodiment, supporting described outdoor fan 40 by described casing 20, so that described fan is positioned at the below of the upper end of described outdoor heat converter 30 with the lower end of motor 42, described fan is positioned at the top of the upper end of described outdoor heat converter 30 with the upper end of motor 42.Therefore, according to this first embodiment, can shorten the air flue between outdoor heat converter 30 and the fan main body 41, thereby can reduce flowing resistance.Consequently, the air quantity of the fan of described outdoor fan 40 is reduced.
Because described fan is positioned at the central part of horn-like parts 43 with motor 42, can reduce passage resistance.
Because described support component 70 comprises cave in the to get motor fixed part 73 of more past below of the installation portion 72 than both sides, so can reduce the resistance of air stream, compared with prior art can make fan lower with the position of motor 42.
Because described electric and electronic components and parts unit 60 is arranged in the top of outdoor heat converter 30, so can effectively utilize the wasted space around the outdoor fan 40.
Because described outdoor fan 40 is arranged on the position away from the opening 3a on the outdoor heat converter 30, that is to say that described outdoor fan 40 is away from the side choking portion of described casing 20, thereby can be that suction resistance is reduced.Consequently, the air quantity of the fan of described outdoor fan 40 is reduced.
Because described outdoor fan 40 near outdoor heat converter 30, increases so pass through the air capacity of this outdoor heat converter 30, thereby can improve the heat exchanger effectiveness of described outdoor heat converter 30.
Because described electric and electronic components and parts unit 60 is arranged between the leading flank and outdoor fan 40 of casing 20, thus can to outdoor fan 40 positions inclined to one side after the wasted space that produces effectively utilize.
Particularly, because described outdoor fan 40 also can be reliably attracted air from the upper part of the outdoor heat converter 30 that is positioned at 60 belows, electric and electronic components and parts unit, descend so can suppress the heat exchanger effectiveness of outdoor heat converter 30.
(the second embodiment of utility model)
Next, with reference to the accompanying drawings the second embodiment of the present utility model is described in detail.
Such as Fig. 7～shown in Figure 10, in the present embodiment, compressing mechanism 50 only comprises that a compressor 5a and fan 4a only comprise an outdoor fan 40, has replaced that compressing mechanism 50 comprises that two compressor 5a, 5b and fan 4a comprise two outdoor fans 40 in the first embodiment.
Particularly, described compressing mechanism 50 comprises a compressor 5a, and on the other hand, electric and electronic components and parts unit 60 is arranged in the left surface of casing 20.
Though not shown, outdoor fan 40 in this second embodiment is the same with the first embodiment, described fan is supported by described casing 20 with motor 42, so that described fan is positioned at the below of the upper end of described outdoor heat converter 30 with the lower end of motor 42, described fan is positioned at the top of the upper end of described outdoor heat converter 30 with the upper end of motor 42, and the lower end of described horn-like parts 43 at described fan with between the upper and lower side of motor 42.
As shown in figure 10, to be arranged in axle center FC be fan center A to described outdoor fan 40 from the center of the overlooking B of described casing 20 towards away from the residing position after the direction skew of the opening 3a on the described outdoor heat converter 30.
Particularly, as shown in Figure 7, skew has occured from the slitter line LL that passes through its fore-and-aft direction of overlooking center B of described casing 20 towards the right flank direction in described outdoor fan 40, that is to say, skew has occured in the direction towards the second side, is displaced to space one side of being surrounded by outdoor heat converter 30 in top view.
Because it is right-hand that outdoor fan 40 is displaced to, so described electric and electronic components and parts unit 60 is arranged between the horn-like parts 43 of the left surface of described casing 20 and described outdoor fan 40.Described air outlet 26 forms from middle position and is displaced to the right side.Other structure, effect and effect are the same with the first embodiment.
(other embodiment)
The utility model can also adopt following structure in the above-described first embodiment.
In the first embodiment, compressing mechanism 50 comprises two compressor 5a, 5b, but in addition, compressing mechanism 50 can comprise a compressor 5a.That is to say that in the outdoor unit 10 in the first embodiment, it is constant electric and electronic components and parts unit 60 can be arranged on front one side, is one and make compressor 5a.
