In addition, although also not shown in the drawings, aircondition 10 also is provided with left and right sides wind direction change blade, heat exchanger temperature detector, and has the off-premises station that inside is provided with compressor, expansion valve and outdoor heat converter etc.

Use Fig. 3~Fig. 7 that the detail operations situation is described below.Longitudinal section when Fig. 3 to Fig. 7 carries out the air draft operation for the aircondition in the expression present embodiment.

At first, the operation of carrying out air draft of subtend horizontal direction or top is described.

Horizontal air draft in the present embodiment or top air draft are meant that discharging air-flow blows distant place to the room on the height on the crown that is higher than the occupant, be mainly used in and discharge cold wind (cooling operation pattern).

What Fig. 3 represented is the state that aircondition 10 shuts down, and Fig. 5 represents is state to horizontal direction or top air draft.

When carrying out horizontal direction or top air draft operation, enter state shown in Figure 4 from state shown in Figure 3 earlier, arrive state shown in Figure 5 again.

As shown in Figure 3, under the state that aircondition 10 shuts down, panel 20 all is in closed condition with wind direction change blade 30.

With the air draft direction setting is when restarting aircondition 10 after level or top air draft (such as refrigerating operation), and as shown in Figure 4, panel 20 moves towards the direction of leaving air inlet 5 under the effect of panel driving mechanism 21, until reaching state B.In addition, when operation took place board driving mchanism 21, support arm 31 was also operated under the driving of support arm drive motors 34, made wind direction change blade 30 towards the direction motion of leaving exhaust outlet 6.

Next, as shown in Figure 5, wind direction change blade 30 rotates under blade driving motor 35 drives, and withstands mutually with the end of downstream side 6a of exhaust outlet 6 until the end near the wind direction change blade 30 of body 10a one side of aircondition 10.Like this, under the state shown in Fig. 5, just can be to horizontal direction or top air draft.

Under this state, owing to withstand mutually with the end of downstream side 6a of exhaust outlet 6 near the end of body 10a one side in the wind direction change blade 30, basically this part is closed, so the cold wind of discharging can not flow to the below from this position.

In addition, the straight line of the opposite side (away from the side of body 10a) of the lower end of the end of downstream side 6a of connection exhaust outlet 6 and wind direction change blade 30 is in same position or is positioned at its top with the horizontal line of the lower end of the end of downstream side 6a that passes exhaust outlet 6, so the air-flow of discharging from exhaust outlet 6 can change blade 30 guiding horizontal direction or top reliably by wind direction.

In addition, the vertical line of straight line and the upper end of the end of downstream side 6a that passes exhaust outlet 6 of upper end and the opposite side (away from the side of body 10a) of wind direction change blade 30 that connects the end of downstream side 6a of exhaust outlet 6 is in same position or than the position in the more approaching discharge wind of described vertical line downstream, so the air-flow of discharging from exhaust outlet 6 can change blade 30 guiding horizontal direction or tops by wind direction reliably.

In addition, because the end of downstream side of wind direction change blade 30 is crooked upward, so air-flow can not flow to oblique below, but guiding horizontal direction or top effectively.

Adopt after the said structure, can refrigeration the time make air-flow do not remain to level or above discharge, so it is temperature lower discharge wind can directly not blow on one's body the occupant, indoor too cold and the indoor mistake of h.d. is cold and the various disadvantages brought in the time of can avoiding room temperature to decline to a great extent.

In addition, because when being positioned at state B in the position of panel 20, the below of the top of exhaust outlet 6 that is panel 20 is closed by the lower end of panel 20, thus can prevent to be inhaled into the air inlet 5 from the part air that exhaust outlet 6 is discharged, thus can eliminate the air-flow short circuit phenomenon.

In addition, when air is inhaled among the body 10a of aircondition 10, when being imported into, also be imported into from the air inlet 5 on the body leading flank by the top of panel 20 and the space of both sides at air inlet 5 from the body 10a end face of aircondition 10.

From to the state of level or top air draft to the operating process of halted state being: the state from level shown in Figure 5 or top air draft enters state shown in Figure 4 earlier, arrives the halted state shown in Fig. 3 again.This a series of operation is just in proper order just in time opposite with the operation from halted state to horizontal air draft state, so in the explanation of this omission to it.

Below the operation of carrying out air draft downwards is described in detail.In the present embodiment, air draft downwards is meant and allows the discharge air-flow blow to the underfooting, is mainly used in and discharges warm braw (the warm operation mode of system).

What Fig. 3 represented is the state that above-mentioned aircondition 10 shuts down, and what Fig. 7 represented is the state of below air draft.

When carrying out below air draft operation, enter state shown in Figure 4, pass through state shown in Figure 6 again from state shown in Figure 3 earlier, arrive state shown in Figure 7 at last.

The operation that arrives Fig. 3 and state shown in Figure 4 is because consistent during with above-mentioned level or top air draft operation, so in the repeat specification of this omission to it.

After state shown in Figure 4, it is state C that panel 20 moves to from air inlet position farthest from air inlet 5 under the driving of panel driving mechanism 21 earlier, as shown in Figure 6.On the other hand, support arm drive motors 34 is further driving, is making wind direction change blade 30 to move to after exhaust outlet 6 position farthest to support arm 31, ordering about wind direction change blade 30 by blade driving motor 35 again on this position rotates, make the body 10a that in refrigerating operation, disembarked just now in the wind direction change blade 30 side end far away near or withstand the end of downstream side 6a of exhaust outlet 6, as shown in Figure 7.

And, by allowing support arm 31 move (bending) by support arm drive motors 34 like that shown in as shown in Figure 7, wind direction change blade 30 is moved to the direction near exhaust outlet 6, just can make the body 10a side end far away of in refrigerating operation, disembarking just now in the wind direction change blade 30 withstand or compress the upper end of the end of downstream side 6a of exhaust outlet 6.

Under state shown in Figure 7, just can carry out air draft downwards.

Because the air-flow of discharging from exhaust outlet 6 changes blade 30 guiding belows by wind direction, and thereby the end of downstream side of wind direction change blade 30, so air draft can not blow to oblique below can blow the below of air to the room effectively to body 10a one lateral bending song.

In addition, because panel is in from air inlet 5 state C farthest for 20 this moments, the below of the top of exhaust outlet 6 that is panel 20 is not closed, so when the body 10a of aircondition 10 sucks air, air not only imports from the top and the both sides of panel 20, but also imports from the air inlet 5 of the leading flank of body 10a by the space of panel 20 bottoms.In addition, because the air-flow of discharging from exhaust outlet imports the below by wind direction change blade 30, so, also can not be imported into air inlet 5 and cause the air-flow short circuit from discharging the air that wind 6 discharges even without the blocking of panel 20.

In addition, the operating sequence from below air draft state to halted state is: earlier enter Fig. 6, state shown in Figure 4 from the state of below air draft shown in Figure 7, arrive halted state shown in Figure 3 at last.Operation during owing to this a series of operation and from halted state to below air draft state is a reversed in order, so just no longer describe at this.

Adopt the words of the present invention embodiment recited above, rely on the wind direction change blade 30 and the position relation of exhaust outlet 6 just can realize the wind direction control of the operation mode of suitable aircondition 10, and can prevent the discharge air-flow reliably from the air-flow short circuit phenomenon that air inlet 5 is inhaled into, realize high efficiency operation.

In sum, the aircondition among the present invention can prevent to discharge the short circuit phenomenon that air-flow enters air inlet reliably, so except being applicable to indoor cooling/heating operation, can also be widely applicable in the aircleaning facility with dehumidifying or dedusting function.
