Be configured with axial-flow fan (air blast portion) 8 and guiding wall 10 in the inside of main body 1, axial-flow fan 8 has impeller 8a.Axial-flow fan 8 is configured between suction side wind path E1 and blowout crosswind road E2, sucks air from suction inlet 2a, 2b, and to blow-off outlet 3 blow out air.Guiding wall 10 extends to below from the rear of axial-flow fan 8, the air of discharging from axial-flow fan 8 is guided to blow-off outlet 3.
Further, be configured with in the inside of main body 1: remove the filter (flowing resistance body) 5 of the dust etc. the air sucked from suction inlet 2a, 2b, by the heat of cold-producing medium or be coldly passed to air and generate the heat exchanger (heat exchange department, flowing resistance body) 7 of Air Conditioning and divide the stabilizer 9 of suction side wind path E1 and blowout crosswind road E2.
Guiding wall 10 coordinates with the lower face side of stabilizer 9 parts forming and blow out crosswind road E2.Guiding wall 10 forms helicoid from axial-flow fan 8 throughout to blow-off outlet 3.
Filter 5 is such as formed as mesh-shape, removes the dust etc. the air sucked from suction inlet 2a, 2b.Filter 5 is being arranged at the downstream of suction inlet 2a, 2b and the upstream side of heat exchanger 7 from suction inlet 2a, 2b to the wind path of blow-off outlet 3.In addition, filter 5 extends to front from the top of heat exchanger 7.
Heat exchanger 7 (indoor heat converter), cooling air for playing function as evaporimeter during blowdown firing, playing function when warming operation as condenser (radiator) and heating air.This heat exchanger 7 is arranged at the downstream of filter 5 and the upstream side of axial-flow fan 8 in the wind path (central portion of main body 1 inside) from suction inlet 2a, 2b to blow-off outlet 3.In addition, in fig. 2, the shape of heat exchanger 7 is formed as surrounding the front portion of axial-flow fan 8 and the shape on top, but this only example, this is not particularly limited.
Heat exchanger 7 is connected with the off-premises station having compressor, outdoor heat converter and throttling arrangement etc. and can be known pattern, thus forms kind of refrigeration cycle.In addition, for heat exchanger 7, such as, use the fin tube heat exchanger of the cross-fin formula be made up of heat pipe and multiple fin.
Blowout wind path 3a is provided with upper and lower wind direction blade (vane) 4a and left and right wind direction blade 4b.Left and right wind direction blade 4b is rotatably arranged between upper and lower wind direction blade 4a and axial-flow fan 8.Upper and lower wind direction blade 4a carries out for the above-below direction in the direction of the air blown out from axial-flow fan 8 parts that adjust, and left and right wind direction blade 4b carries out for the left and right directions in the direction of the air blown out from axial-flow fan 8 parts that adjust.
Upper and lower wind direction blade 4a comprises the 1st fin 4a1 and the 2nd fin 4a2.Above-mentioned 1st fin 4a1 and the 2nd fin 4a2 has drive source alone respectively, thus rotates individually.
1st fin 4a1 closes blow-off outlet 3, the outer surface of constituent apparatus body when operating and stopping.In other words, the 1st fin 4a1 doubles as wind direction control part and main body gabarit design portion.When stopping when operating, the upper surface (wind path side) of the 1st fin 4a1 is formed as convex form.In addition, the 1st fin 4a1 is set to rotate, and the turning cylinder of the 1st fin 4a1 is positioned near the guiding wall of the bottom of blowout wind path 3a.
2nd fin 4a2 is accommodated in when operating and stopping in blowout wind path 3a, and is configured between the 1st fin 4a1 and axial-flow fan 8.2nd fin 4a2 is formed as the 2nd fin 4a2 entirety when operating and stopping and is accommodated in main body 1.On the other hand, the 2nd fin 4a2 is protruding from blow-off outlet 3 in the running.That is, the 2nd fin 4a2 plays function as wind direction control part, and does not play function as main body gabarit design portion.
In addition, though be described in detail afterwards, but in brief, 2nd fin 4a2 (during cross blowing) when level is dried forms a line with the 1st fin 4a1 as shown in Figure 3, being arranged side by side with the 1st fin 4a1 as shown in Figure 4 to while drying (longitudinally) during canyon.
In addition, the turning cylinder of the 2nd fin 4a2 is positioned at the top of blow-off outlet 3 and the position of close stabilizer.And the 2nd fin 4a2 moves to the what is called blowout direct of travel of air-flow that is the front of the 1st fin 4a1 when level is dried, and forms a line with the 1st fin 4a1.In addition, as shown in Figure 3 when side-looking is observed, the configuration formed a line for the 1st fin 4a1 and the 2nd fin 4a2 needs to be formed as following state, that is: linked by the downstream B of the upstream extremity A of the 1st fin 4a1 and the 2nd fin 4a2 and form imaginary line V, then the upstream extremity C of the 2nd fin 4a2 is positioned at and compares above-mentioned imaginary line V position more on the lower (the upstream extremity C being formed as the 2nd fin 4a2 is positioned at the state of the side left from main body 1 relative to imaginary line V).Thus, 1st fin 4a1 and the 2nd fin 4a2 becomes an imaginary fin when level is dried, wherein, this imaginary blade has than the 1st fin 4a1 and the longer imaginary chord length of the 2nd fin 4a2 chord length separately, then playing function as two with respective chord length independent fins to during canyon.That is, can obtain and change fin chord length according to wind direction and the such form of fin itself need not be changed.
In addition, when level is dried, between the 1st fin 4a1 of the configuration that forms a line and the 2nd fin 4a2, guarantee there is gap 20.Particularly, in present embodiment 1, when forming a line, be convex form (being formed as convex form towards main body) upward with the upper surface of the 1st fin 4a1 (face of main body side), the lower surface (with the face of main body opposition side) of the 2nd fin 4a2 is that the mode of convex form (being formed as convex form towards with main body opposition side) down makes the 1st fin 4a1 and the 2nd fin 4a2 rotate respectively to move.
In addition, as shown in Figure 4,2nd fin 4a2 locally more protruding than blow-off outlet 3 to canyon phase, and as shown in Figure 3, the 2nd fin 4a2 when level is dried from blow-off outlet 3 completely protruding (entirety of the 2nd fin 4a2 is protruding from blow-off outlet 3).
On the other hand, the 2nd fin 4a2 is moving to the position between the 1st fin 4a1 and the downstream portion of diffuser 3a1 described later to canyon time shift, and, the mobile posture almost parallel for the downstream portion of above-mentioned 1st fin 4a1 and diffuser 3a1.That is, the 2nd fin 4a2 to during canyon and the 1st fin 4a1 be arranged side by side.In addition, now, the face opposed with the 1st fin 4a1 in 2nd fin 4a2 is formed as towards the outstanding convex form of the 1st fin 4a1, the face opposed with the 2nd fin 4a2 in 1st fin 4a1 is formed as, towards the outstanding convex form of the 2nd fin 4a2, in above-mentioned such mode, the 1st fin 4a1 and the 2nd fin 4a2 being rotated respectively and moving.
Stabilizer 9 divides suction side wind path E1 and the parts blowing out crosswind road E2, and illustrated in Fig. 2 ~ Fig. 4, it is arranged at the downside of heat exchanger 7.Suction side wind path E1 is positioned at the top of stabilizer 9, and blowout crosswind road E2 is positioned at the below of stabilizer 9.
Stabilizer 9 has: be separated suction side stream E1 and blow out the tongue 9a of effluent road E2, temporarily store the diffuser 3a1 of the water-collecting tray 9b of the water droplet dripped from heat exchanger 7 and the upper wall surface (front-surface side wall) as the blowout wind path 3a of blow-off outlet 3.
The upstream portion of diffuser 3a1 extends towards the direction identical with the bearing of trend of the downstream portion of guiding wall 10, and the upstream portion of diffuser 3a1 arranges substantially in parallel with the downstream portion of guiding wall 10 under side-looking.In addition, the upstream portion of diffuser 3a1 has straight line portion under side-looking.As shown in Figure 3 when carrying out side-looking and observing, if the extending direction of the straight line portion of the upstream portion of diffuser 3a1 is set to imaginary line S, then the front portion of this imaginary line S extends in the mode of intersecting with the front surface 1a of main body 1.In addition, the downstream portion 3a1 ' of diffuser 3a1 is to leave from imaginary line S and to extend from the mode that front surface 1a leaves.Downstream portion 3a1 ' bending or inclination under side-looking of diffuser 3a1.And the downstream portion 3a1 ' of diffuser 3a1 more downstream just more leaves imaginary line S.That is, diffuser 3a1 has as lower part under side-looking, that is: this part is the closer to the downstream of diffuser 3a1, just more leaves the imaginary line S of the extending direction of the upstream portion as diffuser 3a1.The end of the downstream portion of diffuser 3a1 arrives lower surface 1d, and thus, the forefront of blow-off outlet 3 is positioned at the scope of lower surface 1d and can not arrives front surface 1a.
In the air conditioner with as above structure, blow-off outlet only main body lower surface opening and not at front surface opening, therefore, it is possible to suppress the situation of the noise (the cold-producing medium circulation sound in the CD-ROM drive motor sound of such as axial-flow fan, the wind noise of axial-flow fan, heat exchanger) that produces from the functional part of body interior directly leakage toward the front.
In addition, in present embodiment 1, the 2nd fin 4a2 is accommodated in when operating and stopping in blowout wind path 3a, and protruding from blow-off outlet 3 in the running.Therefore, the 2nd fin 4a2 can have and is suitable for shape that wind direction controls and do not restrict by the design condition required by body outer surface, thus reliably guarantees to be suitable at least one wind direction control fin of the shape that wind direction controls.Do not improve wind direction controlling by the fin of design condition restriction thereby, it is possible to realize utilizing, and realize the suppression to above-mentioned noise simultaneously.In addition, as mentioned above, the 2nd fin stretches out and forms a line with the 1st fin outside main body, even if thus not there is at the front surface of main body the form of blow-off outlet, also suitably can realize level blowing, and then can also realize taking into account noise suppressed and comfortableness.
In addition, as the evaluation of the appearance design of the outer surface to main body, when operating stopping, under outward appearance is observed, part that can be identified as opening/closing portion is more few better, and in present embodiment 1, a kind of use two fins can be provided and only can pick out the design of an opening/closing portion when operating and stopping.In addition, consider operate stop time the situation about invading from the outer rim of opening/closing portion to body interior such as dust more, and in present embodiment 1, opening/closing portion when using two fins and running stopped suppresses to be one, thus can also expect to suppress the situation that harmful dust etc. invades to body interior.
In addition, in present embodiment 1, the 2nd fin 4a2 and the 1st fin 4a1 forms a line.Therefore, 1st fin 4a1 and the 2nd fin 4a2 becomes an imaginary fin when level is dried, wherein, this imaginary fin has than the 1st fin 4a1 and the longer imaginary chord length of the 2nd fin 4a2 chord length separately, and when to canyon, the 1st fin 4a1 and the 2nd fin 4a2 as two with respective chord length independent fins to play function.That is, can be described as to obtain and change fin chord length according to wind direction and the form of fin itself need not be changed.By obtaining the imaginary fin with the imaginary chord length longer than the chord length of each fin like this, so longer imaginary chord length can be applied flexibly when level is dried, the air-flow of the air of discharging from axial-flow fan is significantly forwards turned to downwards, thus wind direction controlling can be increased substantially.
In addition, when level is dried, between the 1st fin 4a1 configured in the mode formed a line and the 2nd fin 4a2, guarantee there is gap 20.Like this, guaranteeing under the state having gap 20,1st fin 4a1 and the 2nd fin 4a2 is configured in the mode formed a line, so wind during cooling is after passing through the 1st fin 4a1, flow from the gap 20 of the 1st fin 4a1 and the 2nd fin 4a2 along the upper and lower surface both sides of the 2nd fin 4a2, thus the temperature difference on two surfaces of the 2nd fin 4a2 is diminished, thus suppress condensation, can quality be improved thus.Particularly, in present embodiment 1, when forming a line, the upper surface (face of main body side) of the 1st fin 4a1 is convex form (being formed as convex form towards main body) upward, the lower surface (with the face of main body opposition side) of the 2nd fin 4a2 is convex form (being formed as convex form towards with main body opposition side) down, makes the 1st fin 4a1 and the 2nd fin 4a2 rotate respectively to move by this way.By the effect in this bending direction in the face of the 1st fin 4a1 and the 2nd fin 4a2, such that air-flow is easier to flow between the 1st fin 4a1 and the 2nd fin 4a2, and then improve the inhibition of condensation further.
In addition, as shown in Figure 4,2nd fin 4a2 protruding for blow-off outlet 3 local to canyon phase, and as shown in Figure 3, the 2nd fin 4a2 when level is dried from blow-off outlet 3 completely protruding (entirety of the 2nd fin 4a2 is protruding from blow-off outlet 3).Therefore, for the part that the 2nd fin 4a2 stretches out from blow-off outlet 3, the freeing in the suppression of air-flow of side of its always side 1e of autonomous agent 1 can be made, therefore, it is possible to obtain the advantage of easily carrying out wind direction control.
In addition, the 2nd fin 4a2 to during canyon and the 1st fin 4a1 be arranged side by side.And, the face opposed with the 1st fin 4a1 in 2nd fin 4a2 is towards the outstanding convex form of the 1st fin 4a1, the face opposed with the 2nd fin 4a2 in 1st fin 4a1 is towards the outstanding convex form of the 2nd fin 4a2, makes the 1st fin 4a1 and the 2nd fin 4a2 rotate respectively to move by this way.Therefore, when heating, the region that the airflow passes flowed between the 1st fin 4a1 and the 2nd fin 4a2 is impaled by the convex form of the 1st fin 4a1 and the convex form of the 2nd fin 4a2, therefore gently contracted flow is passed through, thus control separation whirlpool, afterwards, by being gently formed as further expanding air-flow, thus the disorder of air-flow is suppressed.Therefore, all in all, the craspedodrome of air-flow is improved, the distance that air-flow arrives floor is extended, thus the effect for the foot being warmed to user can be made to increase.
Above, with reference to preferred embodiment having carried out specific description to content of the present invention, but obviously, as long as those skilled in the art, just various mode of texturing can be adopted based on basic technological thought of the present invention and enlightenment.
