Filter unit 20 is by being provided with filter 21 integratedly, making mobile member 30 that filter 21 moves and constitute along the ways 40 of mobile route guiding filter 21.

At first, if ways 40 is described, then this ways 40 has guide frame 22a, the 22b of the pair of right and left of the mobile route that constitutes filter 21, filter 21 with the mode that can move be bearing in respectively each guide frame 22 (below, under the situation about not distinguishing especially, represent guide frame with label 22) on.

As shown in Figure 3, guide frame 22 has main part 23 that is positioned at the bottom and the arm 24 that extends obliquely upward from main part 23.In main part 23, be equipped with the mobile member 30 of filter 21 described later, and, arm 24 side within it is formed with groove shape guide 25 (with reference to Fig. 2), when common use filter 21 is held in a predetermined position, and has the function that is led in its both sides when filter 21 moves.

And then the front face side of the mobile member 30 in each main part 23 becomes movable guide 41.For this movable guide 41, to be supported around transverse axis 42 rotations mode freely, its bottom can be opened wide towards the place ahead via locking (latch) mechanism in its upper end.That is, movable guide 41 can switch between the closed condition (with reference to Fig. 3 and Fig. 5) that constitutes mobile route and unlimited mobile route are with the open mode (with reference to Fig. 4 and Fig. 6) that can load and unload filter 21.

As shown in Figure 8, filter 21 is bonded at cancellate framework 21a and goes up and to form by netting 21b, and integral body has flexible.On the both ends along the longitudinal of framework 21a, be provided with a plurality of projections 35 so that identical spacing is outstanding in the vertical in its rear side.

As Fig. 5 and shown in Figure 9, mobile member 30 has: along the up and down a pair of toothed belt of the moving direction devices spaced apart of filter 21 configuration with

belt wheel

31,32; Be used to drive the motor 26 (with reference to Fig. 3) of downside belt wheel 31 rotations; And coiling is arranged on the toothed endless belt 33 between two belt wheels 31,32.And then downside belt wheel 31 is being driven by motor 26 and is rotating, upside belt wheel 32 driven rotations thus, endless belt 33 rotations.This mobile member 30 member as pair of right and left in each guide frame 22 disposes each two.

As shown in Figure 9, on endless belt 33, spread all over its complete cycle and be formed with embedded hole 34 with predetermined interval (equidistantly).And then, be entrenched in by the projection 35 that makes filter 21 in the embedded hole 34 of endless belt 33, thereby filter 21 is fastened on the endless belt 33, deviate from from the embedded hole 34 of endless belt 33 by the projection 35 that makes filter 21, thereby filter 21 is disengaged with engaging of endless belt 33.

In this case, as initial position (common use location), install near the mode of downside belt wheel 31 with the lower end part of filter 21.And then under this state, as shown in Figure 5, the upside of filter 21 is directed to arm 24 guiding of framework 22 and is supported from its both sides.And, the downside of filter 21 from its front face side by the back side of movable guide 41 guiding and be supported.And then same with existing air conditioner for filter 21, the roughly whole zone that it covers the weather side of indoor heat converter 12 prevents the dust pollution indoor heat converter 12 that swims in air.

Filter unit 20 for such formation, as shown in Figure 2, to be arranged on guide frame 22a along being spaced laterally apart proper spacing, engaging pawl 28 fastenings of the upper end of the arm 24 of 22b are in the upper end of the bottom framework 11 of main unit 10, and, the installation sheet 29 that utilizes Screw 16 will give prominence to the bottom that is arranged on main part 23 is fixed near the air blow-off outlet 15 of bottom framework 11 of main unit 10, thus, the front face side and the upper face side of the indoor heat converter 12 of these filter unit 20 main body covered unit 10 are installed in the mode that can load and unload on the bottom framework 11 of main unit 10.

Therefore, by filter unit 20 is disassembled from main unit 10, replace filter for example only being installed or filter and other filter units with deodorization functions being installed in this, type can be changed to air conditioner thus with automatic cleaning function, can shared main unit 10 and can deal with different types of machines with low cost.

External packing housing 50 is from outer side covers main unit 10 and filter unit 20, and is installed on the filter unit 20 in the mode that can load and unload.This external packing housing 50 has the front panel 60 that can open and close in its front face side, disposes the movable guide 41 of filter unit 20 in the rear side of this front panel 60.Therefore,,, movable guide 41 is exposed and carry out opening and closing operations, can carry out the loading and unloading of filter 21 by front panel 60 being opened wide or it being disassembled even external packing housing 50 integral demountings are not got off.

Cleaning unit 70 is by being provided with dust-collecting box 71 integratedly and rotating brush 72 constitutes, and described dust-collecting box 71 is taken in the dust of removing from filter 21, and described rotating brush 72 is configured in this dust-collecting box 71, scrapes the dust of getting attached on the filter 21.As shown in Figure 2, dust-collecting box 71 is opening wide below the mobile member 30 and is being exposed between plate 60 and the air blow-off outlet 15 in front under the state of outer surface of air conditioner, be installed in the bottom of external packing housing 50 in the mode that can load and unload making its dust be taken into mouthfuls 76.In addition, rotating brush 72 is driven by drive member such as not shown drive motors and rotates.

In above-mentioned air conditioner, make filter 21 be positioned at Fig. 2 and common position shown in Figure 5 and carry out the air conditioning running.And then, when running finishes or when having carried out running after the running of the scheduled time and finishing etc., carry out the automatic cleaning work of filter 21.Below, with reference to Fig. 5 and Fig. 7 this step is described.In addition, for convenience of explanation, the lower portion of the filter 21 under the state (state when turning round usually) of Fig. 5 is called the initial end of reeling, the upper front end of filter 21 partly is called the coiling terminal part.

At first, each motor 26 of state-driven from Fig. 5 moves endless belt 33, and simultaneously, the rotating brush 72 that drives cleaning unit 70 makes its rotation.Like this, filter 21 descends with endless belt 33, and the initial end of reeling is by also side (rear side of circulation of air direction) rising overleaf around the downside belt wheel 31.At this moment, rotating brush 72 rotates towards the direction opposite with the direction of rotation of downside belt wheel 31, the dust on filter 21 surfaces is scraped fall.

And at this moment, in the part midway of filter 21, projection 35 is chimeric with the embedded hole 34 of endless belt 33 successively.And then, as shown in Figure 7, when the coiling terminal part contacts, finishes cleaning to this part with rotating brush 72, stop endless belt 33 move and the rotation of rotating brush 72 drives, finish to go to the cleaning work in path.

Next, carry out the cleaning work of return path, at this moment, the direction of rotation that makes the moving direction of endless belt 33 and rotating brush 72 is with above-mentioned to go to the path opposite.In this case, by moving of endless belt 33, the coiling terminal part of filter 21 rises, and breaks away from from endless belt 33.

To this, endless belt 33 passes through upside belt wheel 32 towards the rear side bending, but filter 21 is kept erectility by the rigidity of himself, therefore both intervals become big gradually, and then, when filter 21 returns common use location shown in Figure 5, finish the cleaning work of return path.

The dust that is scraped by so automatic cleaning work is taken into mouthfuls 76 from dust and falls in the dust-collecting box 71, and is accommodated in the dust-collecting box 71.When the dust in the dust-collecting box 71 accumulates, be that external packing housing 50 disassembles dust-collecting box 71 from main body side, abandon the dust in the dust-collecting box 71.

In addition, because dust-collecting box 71 is installed between front panel 60 and the air blow-off outlet 15 with the state of the outer surface that is exposed to air conditioner, therefore need not open wide or dismantle front panel 60 just can load and unload this dust-collecting box 71, that is, can dismantle this dust-collecting box 71 in the mode that does not interfere with the front panel 60 of closed condition (common state).

When owing to long-term use to wait need to be serviced, i.e. when the cleaning of indoor heat converter 12, filter 21 and the replacing, repairing etc. of parts on every side thereof, filter simple eye 20 is disassembled from main unit 10.

When carrying out this dismounting, at first external packing housing 50 is disassembled from filter unit 20, the Screw 16 with the installation sheet 29 of Fixed-Filter unit 20 disassembles then.At this moment, even Screw 16 is disassembled, because the engaging pawl 28 on the top of filter 20 is fastened on the top of main unit 10, filter unit 20 forms temporary fixed state, so filter unit 20 can not split away off from main unit 10, can guarantee security.

And then, after Screw 16 is disassembled, unload from main unit 10, thereby filter unit 20 can be disassembled by engaging pawl 28 with filter unit 20.In addition, when being installed to filter unit 20 on the main unit 10, be fastened on the main unit 10 and under the temporary fixed state at engaging pawl 28, the installation sheet 29 usefulness Screws 16 of filter unit 20 are fixed on the main unit 10 get final product filter unit 20.

The front face side by will covering indoor heat converter 12 like this and the filter unit 20 of upper face side disassemble from main unit 10, thereby indoor heat converter 12 exposes to the outside, can easily carry out the washing and cleaning operation of indoor heat converter 12 thus, also can easily carry out the repairing of filter unit 20 and change such maintenance.

And, as Fig. 4 and shown in Figure 6, if make the movable guide 41 of the filter unit 20 that disassembles become open mode, the mobile route of filter 21 is opened wide, then only by deviating from while the projection 35 of the initial end side of coiling that makes filter 21 from the embedded hole 34 of endless belt 33, filter 21 being pulled out towards the below, just can simply filter 21 be disassembled, can carry out the replacing or the cleaning of filter 21.At this moment,, therefore can keep open mode, can easily not carry out extracting of filter 21 with movable guide 41 interference owing on movable guide 41, have retaining mechanism.In addition, when filter 21 is installed, make movable guide 41 become open mode with the state that opens wide mobile route under, on one side the coiling terminal part of filter 21 is got final product in the embedded hole 34 of endless belt 33 is sent into, the projection 35 of the initial end side of coiling of filter 21 is embedded successively to arm 24 on one side.

Dismounting for such filter 21, even filter unit 20 is not disassembled from main unit 10, also can be as mentioned above like that by making front panel 60 open wide or it is disassembled, make the movable guide 41 of its back side be exposed to the outside and open wide and carry out.Therefore, do not carrying out the cleaning of indoor heat converter 12, only carrying out not needing filter unit 20 is disassembled under the situation of the replacing of filter 21 or cleaning.

More than the specific embodiment of the present invention is illustrated, but the present invention is not limited to aforesaid way, can implement various changes within the scope of the invention.

For example, air conditioner of the present invention be not limited to suck room air and freeze, heat, the air conditioner of dehumidifying etc., also can be the air conditioner that only has the air-cleaning function of catching the dust that is comprised in the room air.

And, as the mobile member that filter is moved, being not limited in and using the above-mentioned belt wheel up and down and the mobile member of endless belt, for example also can be to make the tooth bar that is formed on the filter and pinion and the rotation driving by this pinion so that the mobile member of the structure that the mode that filter reverses towards the back side from the front face side of filter unit is transferred.
