  • the fixing groove 244 is concaved upward from the bottom of the panel supporting unit 240 to receive the lower end of the connecting slit 198. That is, when the air exhaust panel 170 moves downward and the lower end of the connecting slit 198 is inserted into the fixing groove 244, the air exhaust panel 170 cannot move downward any more.
  • a plurality of panel projections 250 are further formed on the front portion of the air exhaust panel 170. That is, the panel projections 250 functions to space the front panel 160 away from the air exhaust panel 170 when the air exhaust panel 170 moves upward and downward. That is, during the vertical motion of the air exhaust panel 170, an extreme end of the panel projection 250 slides along the rear surface of the front panel 160.
  • Fig. 14 is a partial perspective view of the rear portion of the air exhaust panel according to an embodiment of the present invention.
  • the frame projection 252 is formed on the rear surface of the air exhaust panel 170. That is, the frame projection 252 allows the front frame 130 to be spaced away from the air exhaust panel 170 when the air exhaust panel 170 moves upward and downward. That is, when the air exhaust panel 170 moves in the vertical direction, the rear end of the frame projection 252 contacts the front frame 130.
  • the panel projection 250 and the frame projection 252 are formed on the front and rear portions of the air exhaust panel 170, respectively, the contact area of the front panel 160 with the front frame 130 is minimized during the movement of the air exhaust panel 170. Therefore, the frictional force between the front panel 160 and the front frame 130 is minimized during the movement of the air exhaust panel 170.
  • an end of the panel link 196" is pivotally coupled to the link coupling hook 242 of the panel supporting unit 240.
  • a first fixing hook 196'a having a shape identical to that of the link coupling hook 242 is formed on the lower end of the shaft link 196'.
  • a second fixing hook 196'b is formed on an upper end of the shaft link 196'. That is, a second link shaft 196"b of the panel link 196" is inserted in the first fixing hook 196"a. Then, the driving shaft 194 is fixedly inserted in the second fixing hook 196'b. Therefore, the shaft link 196' integrally rotates together with the driving shaft 194.
  • Fig. 15 shows a perspective view of the indoor unit for the air conditioner, when the front panel is opened.
  • the front panel 160 is opened.
  • the supporting links 230 is in close contact with the rear surface of the front panel 160 and received in the link seating portions 210 of the front frame 130. Then, the supporting ribs 222 of the front panel 160 maintain their inserted states in the supporting grooves 182 of the front frame 130.
  • the coupling ribs 220 of the front panel 160 rotate in a state where they are inserted in the coupling grooves 180 of the front frame 130. Then, the supporting end 232 of the supporting link 230 slides along the link seating portion 210 of the front frame 130. At this point, the supporting end 232 of the supporting link 230 is not removed from the link seating portion 210 by the link projection 232' of the supporting end 232.
  • the front panel 160 moves as shown in Fig. 15.
  • the supporting end 232 of the supporting link 230 is disposed at a location lower than the hinge unit 234.
  • the supporting end 232 of the supporting link 230 is hooked by the stopper projection 214 of the link seating portion 210. Therefore, the front panel 160 is supported by the supporting link 230 and thus it maintains its opened state as shown in Fig. 15 even when the outer force is released.
  • the front panel 160 When the front panel 160 is opened, the user can replace or repair the internal components.
  • the process is done in a reverse direction to the above-described opening process. That is, the supporting end 232 of the coupling rib 220 is pushed upward. Then, the supporting end 232 of the coupling rib 220 slides upward along the link seating portion 210.
  • the front panel 160 As the supporting end 232 of the supporting link 230 slides upward, the front panel 160 is gradually closed. At this point, when the front panel 160 is further pushed rearward, the supporting rib 222 of the front panel 160 is inserted in the supporting groove 182 of the front frame 130. Then, the front panel 160 is not removed frontward unless predetermined outer force is applied thereto. When the front panel 160 is fully closed, the hinge unit 234 of the supporting link 230 is received in the hinge receiving groove 212.
  • the air conditioner When the air conditioner is turned on, it operates according to a preset mode.
  • the blower fan 114 rotates by the motor assembly 116 to generate air intake force. Then, the room air is introduced into the indoor unit 100 through the air intake grill 132.
  • the introduced air passes through the air filter 144 and the electric dust collector 146, in the course of which the foreign objects contained in the air is filtered off. Then, the air is heat-exchanged with the refrigerant of the heat exchanger 118.
  • the air is forcedly discharged by the blower fan 114 and then guided toward the air outlet by the air exhaust vane 122.
  • the air guided by the air exhaust vane 114 is exhausted downward or frontward of the indoor unit 100. Since the air exhaust panel 170 and the air exhaust vane 122 can be simultaneously or independently driven, the air can be selectively exhausted frontward and/or downward.
  • the frontward air exhaust is controlled by selectively opening and closing the frontward air outlet 174 using the air exhaust panel 170 and the downward air exhaust can be controlled by the air exhaust vane 122. That is, when the air exhaust vane 122 is opened downward, the air forcedly driven by the blower fan 114 is exhausted downward. On the contrary, when the air exhaust vane 122 is not opened and the air exhaust panel 170 is moves upward, the air is exhausted frontward of the indoor unit 100.
  • the present invention since the front panel is opened by pivoting about its upper end, the replace and repair of the internal components of the indoor unit located at a relatively high position on the inner wall of the room can be easily performed. Therefore, the present invention is very likely to be applied to the industry.
