The configuration relation of up-down wind direction board when then representing each operating condition.
Fig. 6 is the side view of state and the stereogram of Air blowing mouth when representing that the running of indoor set stops, and (a) is the side view of indoor set, and (b) is the stereogram observed from oblique downside indoor set.Suitable to Fig. 2, Fig. 4.
When the running of not using air-condition machine A stops, as shown in Figure 6, utilize that control part 60 controls upside up-down wind direction board 170, downside up-down wind direction board 180 makes Air blowing mouth 109b close.Thus, upside up-down wind direction board 170 turns to the anterior position above blowout air channel 109a and is contained, and is hidden upper surface 109c side, blowout air channel, and associating downside up-down wind direction board 180 makes Air blowing mouth 109b close.
Now, left and right blade 170a, 170c of upside up-down wind direction board 170 and central vane 170b, downside up-down wind direction board 180 can form the profile to bottom surface before machine 100 indoor continuously smooth in the wind direction face as outer surface.Therefore, when not using air-condition machine A, become and there is no unnecessary concavo-convex, soft harmony outward appearance, can not interior atmosphere be upset.
Like this, the indoor set 100 of embodiment be closed be divided into multiple upside up-down wind direction boards 170 in the horizontal direction time, the bottom surface of machine 100 is formed smoothly to the wind direction face becoming lower surface during cooling operation by up-down wind direction board of the profile of front panel 106 indoor.
Thus, when stopped air conditioner A, its outer faceplate panels 106 in the past that is formed as, continuously to the level and smooth shape of bottom, becomes and does not have unnecessary concavo-convex clean appearance.Even if therefore, it is possible to provide the air conditioner also can not upsetting interior decoration atmosphere when operating and stopping.
In the present embodiment, the cross-directional length Lb of central vane 170b is made to grow up about 10% than the cross-directional length La of left and right blade 170a and the cross-directional length Lc of left and right blade 170c.If this be in order to prevent making length La, Lb, Lc are equal length, the length of central vane 170b looks short.In addition, be the air quantity that can control to increase central vane 170b.
The side view of state and the stereogram of Air blowing mouth when Fig. 7 is the cooling operation representing indoor set, (a) is the side view of indoor set, and (b) is the stereogram observed from oblique downside indoor set.Suitable to Fig. 2, Fig. 4.
When air conditioner A carries out cooling operation, make upside up-down wind direction board 170 (left and right blade 170a, 170c, central vane 170b), downside up-down wind direction board 180 become with the almost parallel posture of blowout air channel upper surface 109c or level towards using.The cold wind of blowout directly blows to indoor occupant (user) and then can produce uncomfortable sensation, therefore by above-mentioned such operation, suitably change the direction of up-down wind direction board with remote controller 40, make the cold wind of blowout directly not blow to indoor occupant, indoor are kept comfortable temperature humidity.
Now, observe indoor set 100, because indoor set 100 is arranged on the eminence of indoor wall, therefore left and right blade 170a, 170c, the lower surface of central vane 170b, i.e. wind direction face (time closed, becoming the wind direction face of outer surface) is seen, if the front end of blade does not line up, then user may entertain turned position precision and there is the inharmonious sensations such as error.
In the present embodiment, due to the turned position controlling misplacing from the initial front position by the above-below direction of central vane 170b and left and right blade 170a, 170c, therefore, it is possible to do not accepted with there is no inharmonious sensation by user.Such as, in Fig. 7 (a), the front position of central vane 170b gives prominence to about 3mm (position with reference to the state C2 of above-mentioned Figure 15) relative to the front position of left and right blade 170a, 170c in accompanying drawing left.User can be made to coincide for the impression of the wind direction do not expected with having inharmonious sensation during cooling operation with wind direction during observation up-down wind direction board.
In addition, usual up-down wind direction board is retained as approximate horizontal posture, and the distortion therefore caused due to the deadweight of up-down wind direction board becomes large.Owing to easily receiving publicity near indoor set 100 hollow air-blowing outlet 109b, therefore consider the material of up-down wind direction board, shape, do not make the distortion of up-down wind direction board become excessive.In the present embodiment, because upside up-down wind direction board 170 is formed by three wind direction boards, therefore weight is disperseed, and the distortion caused owing to conducting oneself with dignity is few, and this is its feature.
Fig. 8 be represent indoor set heat running time the side view of state and the stereogram of Air blowing mouth, (a) is the side view of indoor set, and (b) is the stereogram observed from oblique downside indoor set.Suitable to Fig. 2, Fig. 4.
When air conditioner A carries out heating running, the posture that upside up-down wind direction board 170 (left and right blade 170a, 170c, central vane 170b) is become close to vertical shown in Fig. 8 uses.In addition, downside up-down wind direction board 180 posture that to become relative to vertical guide be predetermined angular is made to use.Like this, the warm braw flowed in the 109a of Air blowing air channel indoor machine 100 blows out downward, arrives Near Ground, and near warm vola, making indoor is a home from home.
Now, observe indoor set 100, because indoor set 100 is arranged on the eminence of indoor wall, therefore left and right blade 170a, 170c, the upper surface of central vane 170b, i.e. wind direction face (time closed, becoming the wind direction face of inner surface) is seen, if the front end of blade does not line up, then user may entertain turned position precision and there is the inharmonious sensations such as error.
In the present embodiment, due to the turned position controlling misplacing from the initial front position by the above-below direction of central vane 170b and left and right blade 170a, 170c, therefore, it is possible to do not accepted with there is no inharmonious sensation by user.Such as, the difference in height d (gap) of central vane 170b and left and right blade 170a, 170c side-looking in Fig. 8 (a) is viewed as about 13mm (predetermined distance).User can be made to coincide for the impression of the wind direction do not expected with having inharmonious sensation when heating running with wind direction during observation up-down wind direction board.Compared with Fig. 7, when Fig. 8, the difference in height d of central vane 170b and left and right blade 170a, 170c is larger.Due to the dislocation relation of the axle of central vane 170b and left and right blade 170a, 170c, along with aperture increases, the dislocation of blade increases.
Usually, the difference of the room temperature when difference of the warm braw temperature of room temperature when heating and blowout is greater than refrigeration and the cold wind temperature of blowout.Therefore, the temperature difference between the wind direction face in the table of downside up-down wind direction board 180 becomes large, and the difference due to thermal expansion produces the bending phenomenon of downside up-down wind direction board 180.Especially consider when heating because temperature difference causes the phenomenon that bends.Therefore, downside up-down wind direction board 180 such as makes hollow bulb play the function of air heat insulation by becoming hollow, and the heat reduced between the wind direction face in the table of up-down wind direction board moves.
Warm braw when heating running blows out down, and making rapidly indoor is comfort conditions.Now, warm braw blows to the upside central vane 170b of up-down wind direction board 170 and the wind direction face of left and right blade 170a, 170c, makes air-flow down.Now, owing to there is difference in height d at central vane 170b and between left and right blade 170a, 170c, the air-flow of the lower surface of central vane 170b is therefore blown to around the upper surface to left and right blade 170a, 170c.Therefore, the upper surface of left and right blade 170a, 170c and the temperature difference of lower surface reduce, the bending effect diminished that the difference with the thermal expansion in the table of left and right blade 170a, 170c causes.
And, when cooling operation, make up-down wind direction board situation down can think little as mentioned above, but in this situation, owing to there is difference in height d at central vane 170b and between left and right blade 170a, 170c, therefore blow to the air-flow of the lower surface of central vane 170b also around the upper surface to left and right blade 170a, 170c.Therefore, the upper surface of left and right blade 170a, 170c and the temperature difference of lower surface reduce, and have the effect suppressing to produce condensation at the upper surface of left and right blade 170a, 170c.
As discussed above, even if the air conditioner A that also well can keep Air blowing mouth 109b outward appearance in operation process can be provided.
