To the ruuning situation of air-conditioner indoor unit according to the present invention be described below.
In case air-conditioner moves under refrigerating mode, air just flows into the inside of air-conditioner by cross flow blower 192, that is to say blower motor 194 runnings and the voltage generation torque that applies by the outside.When torque is rotated cross flow blower 192, just produce suction.Therefore, by suction grille 140 air is introduced indoor unit 100 from outside (regulating the space of air).
The outdoor air that flows into indoor unit 100 passes heat exchanger 190.Make the air cooling of passing heat exchanger 190 by cold-producing medium in heat exchanger 190 internal flows.
Air themperature through heat exchange in heat exchanger 190 becomes relatively low, and flows into cross flow blower 192.
The Cryogenic air that flows into cross flow blower 192 is discharged and is guided in the bottom compartment along the cylinder direction of cross flow blower 192.
The air that is directed passes the exhaust port 202 of air discharge grille 200.At this moment, the emission direction of air is by the exhausting blade 204 and blinds 206 controls that are installed in the exhaust port 202, and air is discharged in the space of carrying out air conditioning then.
To describe the rotation situation of exhausting blade 204 below in detail.Fig. 7 illustrates according to the present invention the rear view the when exhausting blade in the air-conditioner indoor unit and auxiliary blade are closed.Fig. 8 illustrates according to the present invention the rear view the when exhausting blade in the air-conditioner indoor unit and auxiliary blade move under refrigerating mode.Fig. 9 illustrates according to the present invention the rear view the when exhausting blade in the air-conditioner indoor unit and auxiliary blade move under heating mode.
When indoor unit under situation about moving under the refrigerating mode, when exhausting blade 204 is in as shown in Figure 7 closed condition, exhausting blade 204 because sliding-vane motor 204 ' driving and rotate in the counterclockwise direction.At this moment, because guiding boss 226 is arranged on the A place, top of guiding groove 234, so if exhausting blade 204 rotates in the counterclockwise direction, then auxiliary blade 208 also rotates together in the counterclockwise direction in company with exhausting blade 204.
Therefore, the guiding air discharged is discharged towards the part that the interior space makes progress relatively.Because blade 204 (in Fig. 8 with the direction shown in the arrow) in the counterclockwise direction rotates predetermined angular, so upwards the air of exhausting blade 204 is passed in guiding, and the surface of air discharged contact-impact exhausting blade 204, thereby make the air of relatively large amount be directed upwards.
Like this, air is upwards discharged in refrigerating mode, so that the principle of utilizing cold air to flow downward makes the circulation of air trim ground.
In addition, in refrigerating mode, auxiliary blade 208 also rotates in the counterclockwise direction as exhausting blade 204.Therefore, upwards guide a large amount of air, thereby cool off the interior space more apace in the interior space.
Below with reference to Fig. 7 and Fig. 9 the heating ruuning situation of indoor unit is described in detail.
When air-conditioner began to move under heating mode, sliding-vane motor 204 ' make exhausting blade 204 rotated (in Fig. 9 with the direction shown in the arrow) along clockwise direction.Thereby, as shown in Figure 9, the guiding boss 226 of exhausting blade 204 from the top A of guiding groove 234 to lower slider.
When the guiding boss 226 that slides along guiding groove 234 arrives the bottom B of guiding groove 234, exhausting blade 204 stops operating, that is to say, owing to the mode of auxiliary blade 208 being arranged to do not rotate along clockwise direction, so guiding groove 234 plays brake component by exhausting blade 204.
Like this, when exhausting blade rotates along clockwise direction, discharge downwards in the interior space by the air that exhaust port 202 is discharged.Because exhausting blade 204 (in Fig. 9 with the direction shown in the arrow) along clockwise direction rotates predetermined angular, so the air of discharging by exhausting blade 204 is guided downward, and by the surface of exhausting blade 204 guiding discharged air downwards.
As mentioned above, when indoor unit moves under heating mode, compare with the situation of refrigerating mode, air along relatively by under the direction discharge.In heating mode, discharge air downwards, thereby so that the principle of utilizing the hot-air tendency to rise makes air circulate reposefully in the interior space.
Simultaneously, in heating mode, auxiliary blade 208 does not rotate together with exhausting blade 204 and remains on halted state.Its former because: be interconnected such as the operating unit of display unit 210 and the such parts of motor that are arranged on auxiliary blade 208 back.In order to make these parts move to other position, must increase the size of indoor unit, thereby not choose this mode.In addition, the air that in heating mode, makes downward discharge to more by under direction discharge, therefore because air capacity is little, so need not to make auxiliary blade 208 to rotate.
By to guiding more substantial air, can upwards guide more air than auxiliary blade 208 direction more up.On the other hand, can utilize following space, thereby this space is because sealing and utilized and cause making quantitative air break-in by auxiliary blade 208.Therefore, can improve the turning efficiency of above-mentioned air containment greatly.
