As Fig. 9 and even shown in Figure 13, reducing gear 22 has: two minutes shell 50, be housed in the 1st gear the 52, the 2nd gear unit and the 3rd gear unit 54,56 in the shell 50.Shell 50 constitutes by the 1 half shell 50a that is fixed on heat exchanger 10 with respect to the 2 half shell 50b of the 1 half shell detachable, and the 1 half shell 50a is towards the central authorities of heat exchanger 10 and install, and on the other hand, the 2 half shell 50b is installed in the end side of heat exchanger 10.

In addition, the inner face at the 1 half shell 50a is formed with: with the 2nd gear support member 58 of the driving shaft 20a adjacency of CD-ROM drive motor 20, with the 3rd gear support member 60 of the 2nd gear support member 58 adjacency.As shown in figure 13, the outstanding face 50c that is provided with half shell 50a of the 2nd gear support member 58 and the 3rd gear support member 60, form tabular surface, this tabular surface extends to the direction vertical with the installed surface 50d of the relatively hot interchanger 10 of the 1 half shell 50a, and CD-ROM drive motor 20 is fixed the outer surface of this tabular surface 50c.

On the other hand, the 2 half shell 50b has the 1st tabular surface 50e that the tabular surface 50c with the 1 half shell 50a extends in parallel, and face is formed with within it: with the 1st gear support member 62 of the driving shaft 20a concentric arrangement of CD-ROM drive motor 20, with the 2nd gear support member 64 of the 2nd gear support member 58 concentric arrangement of the 1 half shell 50a.In addition, clipping on the 2nd tabular surface 50g that aftermentioned peristome 50f ground and tabular surface 50e extend in parallel the 3rd gear support member 66 of the 3rd gear support member 60 concentric arrangement of integrally formed and the 1 half shell 50a.

Have, the 1st gear 52 forms as individual gears again, and the 2nd gear unit 54 and the 3rd gear unit 56 form as 2 grades of gears with small-diameter gear and large diameter gear.The 1st gear 52 is installed on the driving shaft 20a of the CD-ROM drive motor 20 that is fixed in the 1 half shell 50a top, and is freely being supported by the 1st gear support member 62 rotations that are formed on the 2 half shell 50b.On the other hand, the 2nd gear unit, the 3rd gear unit 54,56 are freely being supported by the 2nd gear support member 58,64 and 60,66 rotations of the 3rd gear support member that are formed on the 1 half shell and the 2 half shell 50a, the 50b respectively.

In addition, the 1st gear 52 that is installed on the driving shaft 20a of CD-ROM drive motor 20 is meshed with the large diameter gear 54a of the 2nd gear unit 54, the small-diameter gear 54b of the 2nd gear unit 54 is meshed with the large diameter gear 56 of the 3rd gear unit 56, and the small-diameter gear 56b of the 3rd gear unit 56 is meshed with sector gear 36.For this reason, the face of tooth of the tooth bottom surface of the small-diameter gear 56b of the 3rd gear unit 56 and the gear part 44 of sector gear 36 has complementary shape, the tooth bottom surface semicircular in shape of small-diameter gear 56b.In addition, (when front panel 14 is installed) interfered gear part 44, the face of tooth of small-diameter gear 56b to form to be predetermined angular () convex face for example, 90 degree, different with involute gear, there is not smooth face of tooth in it for fear of with sector gear 36 engagement the time.Have, the large diameter gear 56a of the big footpath of the 1st gear the 52, the 2nd gear unit 54 and small-diameter gear 54a, 54b, the 3rd gear unit 56 forms involute gear again.

Have, the small-diameter gear 56b of the 3rd gear unit 56 is meshed with sector gear 36 again, therefore, forms peristome 50f going up corresponding to the shell 50 (the 2 half shell 50b) of the engaging piece of small-diameter gear 56b and sector gear 36.In addition, front panel 14 sides at heat exchanger 10 are provided with filter (not shown), invade in order to the dust that prevents from the peristome 14a of front panel 14 inhaled air, to be contained, but, reducing gear 22 is directly exposed in the peristome 14a of front panel 14 inhaled air, therefore, suck the dust that is contained in the air and might invade the inside of reducing gear 22 through the peristome of shell 50.If invade dust in the reducing gear 22, bring harmful effect then can for the work etc. of reducing gear 22, for this reason, between the large diameter gear 56a and small-diameter gear 56b that constitute the 3rd gear unit 56, the dust that prevents of integrally formed circle is invaded flange (partitions) 56c.This prevents dust intrusion flange 56c, form roughly concordant with the 1st tabular surface 50e of above-mentioned the 2 half shell 50b, peristome on this face is rounded as the complementary shape that prevents dust intrusion flange 56c, other reducing gears 22 except that the small-diameter gear 56b of the 3rd gear unit 56, be housed in by the dust that prevents of shell 50 and the 3rd gear unit 56 and invade in the formed roughly airtight space of flange 56c, therefore, can prevent that dust is to this space intrusion.

In addition, the 1 half shell 50a, have two installation portions 68,70 that are used to be installed on the heat exchanger 10, one installation portion 68, inserting near the end of heat exchanger 10 between a plurality of fin (not shown) that constitute heat exchanger 10, and its leading section is buckled in a plurality of copper pipes part that connects fin, and another installation portion 70, screwed togather to be fixed on one of 2 end plates being configured in a plurality of fin two ends.

In addition,, for example use stepping motors as CD-ROM drive motor 20, but in order to set the driving force that is activated motor 20 angle of oscillation of the sector gear of swinging 36, need to set the anglec of rotation of CD-ROM drive motor 20.Therefore, at the limiting section 72 of the gear part 44 end butts of above-mentioned the 1st tabular surface 50e of the 2 half shell 50b local integrally formed and sector gear 36, the position of sector gear 36 and limiting section 72 butts when setting initial point and closing in order to be positioned at moveable panel 18.

Also have, only in respect to the predetermined angular scope of oscillation center, form the gear part 44 of sector gear 36, moveable panel 18 swing to from the release position closed position, with basket 4 butts (with reference to Figure 10), the face of tooth of tooth that then is positioned at gear part 44 ends of sector gear 36 carries out face with the tooth bottom surface of the small-diameter gear 56b of the 3rd gear unit 56 and contacts.At this moment, the 20 further short time of CD-ROM drive motor rotate, and the small-diameter gear 56b of the 3rd gear unit 56 are further counterclockwise rotated, therefore in Figure 10, if there is not limiting section 72, then may remove the slippage phenomenon of the engagement of sector gear 36 and small-diameter gear 56b.Therefore, limiting section 72 is not only set sector gear 36 location and is used initial point, also plays the effect that prevents to jump the tooth device.

In addition, consider the disassembly of the small-diameter gear 56b of 36 pairs of gear units 56 of sector gear, set the position of limiting section 72, so that when moveable panel 18 is closed, limiting section 72 is connected to the side that is positioned at the tooth of the opposition side end of the tooth of gear part 44 ends of small-diameter gear 56b butt.

Have again, sector gear 36 is installed in a end at long driving shaft 24, at driving shaft 24 with constitute and have a little gap between the long connecting rod 16a driving shaft jack of each linkage 16, therefore, be positioned at moveable panel 18 ends of sector gear 36 sides and the end of opposition side and can fully do not open and close simultaneously.When moveable panel 18 is closed, compare with the end of the moveable panel 18 that is positioned at sector gear 36 sides, the delay of closing of a little takes place in the end of opposition side, if set limiting section 72 the position so that when the butt basket 4 of the end of the moveable panel 18 that is positioned at sector gear 36 sides, sector gear 36 abuts to limiting section 72, then also sometimes the opposition side end of moveable panel 18 not with basket 4 butts, outward appearance is bad.Therefore, the location of limiting section 72 positions, make after the end butt basket 4 of the moveable panel 18 that is positioned at sector gear 36 sides, be further rotated the end that makes moveable panel 18 and the moment of basket 4 butts at CD-ROM drive motor 20, sector gear 36 is connected to limiting section 72.

Below, the effect of the indoor set 2 of the air conditioner of the present invention of above-mentioned formation is described.

As shown in Figure 2, when air-conditioner operation stopped, moveable panel 18 and front panel 14 driving fits were closed the peristome 14a of front panel 14 by moveable panel 18.At this moment, sector gear 36 and limiting section 72 butts that are formed on the 2 half shell 50b, the long connecting rod 16a and the linearly approximate vertical of short connecting rod 16b that constitute each linkage 16 are arranged, and simultaneously, are housed among connecting rod accepting hole (rectangular aperture portion) 14b of front panel 14.

If connect the running switch by remote control, then utilize interconnective off-premises station of coolant piping and indoor set 2 work, in indoor set 2, in the time of pressure fan 11 work, open control break-in blade 12 (with reference to Fig. 3).Simultaneously, CD-ROM drive motor 20 rotates specified quantities, makes sector gear 36 swing the state of predetermined angular to Fig. 3 from the state of Fig. 2 via reducing gear 22.Consequently, in the time of sector gear 36 swings, driving shaft 24 rotation predetermined angulars, therefore, via linkage 16 open moveable panel 18.At this moment, the long connecting rod 16a that constitutes each linkage 16 is the center swing with the axle center of driving shaft 24, slides along the circular-arc slotted hole 32a of short connecting rod installation portion 32 and the slotted hole 34a of timber 34 in the both ends of short connecting rod 16b.Its result, moveable panel 18 forwards almost parallel moves, consider the outward appearance when moveable panel 18 is opened, as shown in Figure 3, set the length of long connecting rod 16a and short connecting rod 16b so that the opening at rear, moveable panel 18 upper end is bigger than the opening interval at bottom rear at interval.

Next, disconnect the running switch by remote control, the running of off-premises station and indoor set 2 stops, in the indoor set 2, and when pressure fan 11 stops, closing control break-in blade 12 (with reference to Fig. 2).Simultaneously, CD-ROM drive motor 20 rotation specified quantities, make the state of sector gear 36 from the state swing predetermined angular of Fig. 3 to Fig. 2 via reducing gear 22, after the end of sector gear 36 abutted to limiting section 72 on the 2 half shell 50b, CD-ROM drive motor 20 stopped.Consequently, in the time of sector gear 36 swing, driving shaft 24 rotation predetermined angulars, therefore, by linkage 16 moveable panel 18 rearward almost parallel move, close with basket 4 driving fits.

Air conditioner of the present invention has and opens and closes moveable panel freely, adopted and prevented that the dust intrusion is installed in the method for the reducing gear between drive source and the moveable panel, therefore can make that the running of reducing gear is bad anti-ly to terminate in possible trouble, can be used as uses such as general home-use air conditioner.
