The specific embodiment

Below, embodiments of the present invention are described with reference to the accompanying drawings.

Fig. 1 to Fig. 3 is the longitudinal section of wall hanging air conditioner.1 expression air conditioner main body, described main body 1 is installed on the wall 3.In described main body 1, be provided with indoor side heat exchanger 5 and cross flow fan 7.Top air entry 9 forms grille-like on the 1A of the top of described main body 1, at the exterior region 1B of described top 1A, the upper end 11A of suction grille 11 is that center hinge connects with fulcrum 12, under this state, from main body 1 front lower end 11B can be installed with freely opening wide.

In the inboard of described suction grille 11, lifting is installed with the breathing filter 13 with filter material freely.

Fig. 4 is the stereoscopic figure of the state after breathing filter 13 that corresponding diagram 3, expression have a filter material 14 descends.

In the bottom of air conditioner main body 1, form the air blow-off outlet 21 that is surrounded by scroll portion 17 and tongue 19, configuration wind direction alteration board 23 in described air blow-off outlet 21.Described wind direction alteration board 23 is by being provided with following structure: the lower horizontal plate 23A of the narrow width of extending along its length at the downside of air blow-off outlet 21, the upper horizontal plate 23B that extends along its length at the upside of air blow-off outlet 21 and many vertical panel 23C that extend at the short side direction of air blow-off outlet 21.

Fig. 5 A～Fig. 5 C represents the elevating mechanism of breathing filter 13.

In the present embodiment, described elevating mechanism is provided with following structure: at the fixing guider 41 of the inner face of suction grille 11, by freely filter holding section 43 of described guider 41 guiding liftings, can freely insert the taking-up portion 45 of described filter holding section 43 and be installed in filter material 14 in the described taking-up portion 45.Guider 41 is configured in the both sides of suction grille 11, from two side directed filter holding sections 43.And, the 47th, upper guide, described upper guide 47 only guides the upper end 14A of filter material 14, and with reference to Fig. 1, described upper guide 47 bendings extend between the top of the top 1A of main body 1 and indoor side heat exchanger 5.

The drive system of breathing filter 13 then, is described.

Described breathing filter 13 is fixed on the inner face of suction grille 11 by the guider 41 of pair of right and left, simultaneously, fixed part 51 is configured in each lower end of a pair of guider 41.Pinion 52 is configured on each fixed part 51, connects each pinions 52 by connecting axle 53 it is rotated simultaneously, on each pinion 52, connecting can positive and negative rotation dc stepper motor.

Tooth bar 43A engagement on each pinion 52 and the outer wall that is fixed on filter holding section 43, when dc stepper motor drove, pinion 52 rotated synchronously, made the rotation direction of filter holding section 43 and pinion 52 correspondingly carry out lifting.

In addition, end 54A at the upper end of fixed part 51 fixing belt 54, the other end 54B of described belt 54 twists on the upper cylinder 56 that is fixed in filter holding section 43 upper ends, extends downwards, the roughly pars intermedia 54C of belt 54 is fixed on the upper end of taking-up portion 45, further extend downwards then, twist on the lower cylinder 57 of the lower end of being fixed in filter holding section 43, extend upward, be fixed on the bottom of fixed part 51.Like this, when dc stepper motor just changes, engagement by above-mentioned tooth bar 43A and pinion 52, filter holding section 43 descends, simultaneously, because the roughly pars intermedia 54C of belt 54 is fixed on the upper end of taking-up portion 45, so, when filter holding section 43 dropped to the minimum point of filter holding section 43, shown in Fig. 5 C, taking-up portion 45 further dropped to the minimum point of this taking-up portion 45 of below.On the other hand, when dc stepper motor reverses,, guide filter holding section 43 into top, simultaneously, rise to taking-up portion 45 in the filter holding section 43 and be accommodated in assigned position by belt 54 by the engagement of tooth bar 43A and pinion 52.

Present embodiment, for example corresponding signal input from remote controller (not shown), as mentioned above, when breathing filter 13 begins to descend, as shown in Figure 2, with described down maneuver linkedly from the open at its front suction grille 11 of air conditioner main body 1, between the lower end of suction grille 11 and air conditioner main body 1, form a certain size gap 100, breathing filter 13 drops to assigned position by described gap 100.

That is, as shown in Figure 6, cam part 61 is set near the lift path of filter holding section 43 (breathing filter), an end 61A of described cam part 61 is connected the fixed part of suction grille 11 by fulcrum 62 hinges.

On the other end 61B of described cam part 61, form abutting part 63 outstanding in the mobile route of filter holding section 43.And filter holding section 43 descends, and as shown in Figure 7, when the lower end of filter holding section 43 43A and abutting part 63 butts, abutting part 63 is open, and cam part 61 is the direction rotation of middle mind-set arrow A with fulcrum 62.When filter holding section 43 further descends, as Fig. 8 and shown in Figure 9, abutting part 63 unclamps from the lower end 43A of filter holding section 43, cam part 61 is that fixed part 65 butts of the press section 61C of cam part 61 and air conditioner main body 1 are further rotated to the direction of arrow A in the center with fulcrum 62.

In the present embodiment,,, set the fixed part 65 of air conditioner main body 1 and the size between the filter holding section 43 narrower along with the decline of filter holding section 43 as Fig. 8 and shown in Figure 9.Therefore, when filter holding section 43 drops to assigned position, the cam part 61 that suction grille 11 is positioned between fixed part 65 and the filter holding section 43 is pushed open, and from the open at its front of air conditioner main body 1, form gap 100 between the lower end of suction grille 11 and air conditioner main body 1, this gap 100 has the size that breathing filter 13 is descended.

Because above-mentioned formation is provided with following structure: the signal input of corresponding remote controller, when breathing filter 13 begins to descend, suction grille 11 is with described down maneuver interlock and from main body 1 open at its front, breathing filter 13 is by dropping to assigned position by the gap 100 that described opening produced, therefore has following effect: the elongated open portion of breathing filter decline usefulness and the cover part that stops up described peristome need not be set in the bottom of air conditioner main body 1, thereby make simple for structureization, reduced number of components, can reduce production costs.In addition, owing to do not had cover part in appearance, so, can obtain product attractive in appearance.

More than, according to an embodiment the present invention has been described, but the present invention is not limited to this significantly.

Because correspondence of the present invention is from the signal input of remote controller etc., suction grille is from the main body open at its front, and breathing filter drops to assigned position by its gap, so, complicated structure that need not be as prior art just can make breathing filter drop to assigned position.
