The specific embodiment

Below, use accompanying drawing that embodiments of the invention are described.Same-sign among the figure is represented same thing or suitable thing.

At first, use Fig. 1, Fig. 2, Fig. 3, Fig. 5 that the overall structure of air conditioner is described.Fig. 1 is the structure chart of the air conditioner of embodiment.Fig. 2 is the sectional view of the indoor set of air conditioner.Fig. 3 is refrigeration, the sectional view when dehumidifying is turned round of indoor set.Fig. 5 is the takeoff stereogram of state of the front panel of expression indoor set.

Air conditioner 1 usefulness connecting pipings 8 connects indoor set 2 and off-premises stations 6, carries out air conditioning to indoor.Indoor set 2 is placed indoor heat exchanger 33 at the central portion of chassis base 21, at the Air Blast fan 311 of the downstream of heat exchanger 33 configuration with the cross flow fan mode of the width length about equally of heat exchanger 33, the installation dish 35 etc. that uncovers, and with escutcheon 23 they are covered, front panel 25 is installed in the front of escutcheon 23.On this escutcheon 23, on have the air suction inlet 27 of air in the suction chamber and blow out the air blow-off outlet 29 of the air of having adjusted humiture.

Indoor heat exchanger 33 makes heat transfer area become big for the space of using indoor set 2 as far as possible effectively and makes outstanding upward shape, and is provided with in the mode of crossing over Air Blast fan 311.Air Blast fan 311 make blow out air flow direction have with the length width about equally of Air Blast fan 311 blow out air channel 29, blow out air-flow and blow out the left and right directions deflection that air channel 290 left and right sides wind direction board 295 midway makes air-flow, and then make the above-below direction deflection of air-flow and be blown out to indoor with the up-down wind direction board 291 that is configured on the blow-off outlet 29 with being configured in.

If Air Blast fan 311 rotations, then room air blows out from air blow-off outlet 29 by indoor heat exchanger 33, Air Blast fan 311 from the air suction inlet 27 that is arranged on the indoor set 2.

Air Blast fan 311, filter 231, indoor heat exchanger 33 are installed on chassis base 21, the basic internal structure body of uncover dish 35, up-down wind direction board 291, left and right sides wind direction board 295 etc.And these basic internal structure bodies are installed in the cabinet that is made of chassis base 21, escutcheon 23, front panel 25 20 and constitute indoor set 2.

In addition, bottom one side of plate 25 in front as shown in Figure 5, disposes the display part 397 that shows operational situation and receives light accepting part 396 from the ultrared operation signal of the remote controller 5 of other one.

The following air blow-off outlet 29 that is formed at escutcheon 23 disposes in abutting connection with the cutting part with front panel 25, and is communicated with the air channel 290 that blows out of depths.Up-down wind direction board 291 constitutes under closed state, roughly covers to blow out air channel 290 and have the bigger curved surface continuous with the bottom surface of indoor set 2.These up-down wind direction boards 291 are fulcrum with the turning cylinder that is arranged on both ends, according to the indication from remote controller 5, utilize CD-ROM drive motor to rotate needed angle when air conditioner 1 running and open air blow-off outlet 29 as shown in Figure 3 and keep this state.When the running of air conditioner 1 stops, controlling these up-down wind direction boards 291 and close air blow-off outlet 29.

Indoor set 2 possesses control circuit board in the electrical box of inside, be provided with microcomputer on this control circuit board.This microcomputer receives the signal from various sensors such as indoor temperature transmitter, indoor humidity sensors, and by means of the operation signal of light accepting part 396 receptions from remote controller 5.This microcomputer is based on these signals, Air Blast fan 311, up-down wind direction board CD-ROM drive motor, left and right sides wind direction board CD-ROM drive motor etc. in the control room, and administer with off-premises station 6 communicate by letter unified control indoor set 2.

Filter 231 is the parts that are used for removing the contained dust of the room air that is inhaled into, is configured in air suction inlet.The dish 35 that uncovers is configured in the bottom below of the both sides, front and back of indoor heat exchanger 33, the condensate water that produces in indoor heat exchanger 33 when being received in cooling operation or during the dehumidifying running and being provided with.The condensate water that receives and compile is discharged to outdoor by drainage piping 37.

Secondly, use Fig. 2~Fig. 4 that the folding and unfolding structure for improving the additional functional part of air quality that present embodiment possesses is described.Fig. 4 is the takeoff sectional view of state of the front panel of expression indoor set.

As mentioned above, the humiture in the nearest air conditioner in conditioning chamber, also expectation improves indoor air quality.Method as the raising that realizes air quality, various functions such as the air purifying function of anaphylactogens such as pollen or house moss or deodorization, additional anion, additional charged fine water droplet, humidification have been considered to remove, but, here with can be capturing the dust more than the particle diameter 10 μ m near 99.9% high efficiency, and the air cleanness filter with deodorization function be that example describes.

Air cleanness filter 331 is to make nonwoven contain deodorant and be converted into pleated to make it have the filter of static, has air purifying function.Make this air cleanness filter 331 towards the bottom of heat exchanger 33 upstream sides and be arranged on air channel between the filter 231 of suction inlet 27.Specifically, on the packaged unit 333 that constitutes this air channel, form the carriage 333c that ventilates freely, suspension and folding and unfolding air cleanness filter 331 on this carriage 333c.

Thus, in running during air conditioner, the air-flow that is caused by Air Blast fan 311 is shown in the arrow of Fig. 3, and its part is by air cleanness filter 331, catch the foul smell composition when removing anaphylactogen such as pollen contained in the air-flow that passes through or house moss, embody deodorization functions.This air cleanness filter 331 can accumulate dust such as above-mentioned pollen or house moss because of long-term use, so the cleaning that need wash etc. with 2~3 years frequencies about once.

Therefore, in order the opening 333a of air cleanness filter 331 loading and unloading usefulness to be set at the suitable position of packaged unit 333 from the air cleanness filter 331 of front panel 25 sides loading and unloading folding and unfolding among the 333b of folding and unfolding portion of air cleanness filter 331.On the opening 333a of this loading and unloading usefulness, load and unload mounting cover parts 335 freely.In addition, front panel 25 is supported on upper axis the last forequarter of escutcheon 23 as shown in Figure 4, and utilizes the elasticity etc. of material to make the bottom takeoff on the packaged unit 333 and open and close freely and constitute.By making this structure, when cleaning air cleanness filter 331, needn't just can load and unload air cleanness filter 331 simply by tool using.

Like this, even cover 335 and front panel 25 are are all loaded and unloaded formation freely, not only size is little for one side's cover 335, and the loading and unloading object has only packaged unit 333, and form with the contact site of packaged unit 333 at grade etc., improved adaptation, can reduce air and leak, to this, not only size is big for the opposing party's front panel 25, and if will make the main body driving fit of itself and indoor set 2, then the parts of the object of institute's driving fit are of all kinds, and, in order to make the outward appearance sight that beautifies, shape also complicates easily, can not make their driving fits eventually and reduce the air leakage with the less power of freely loading and unloading usefulness.

In general, if the running pressure fan then produces air-flow between the suction oral-lateral of pressure fan and suction inlet, produce pressure differential by this air-flow, ambient air is inhaled into from minimum gap between pressure fan and the suction inlet, and the air by suction inlet is not inhaled in the pressure fan yet and is blown.In air conditioner, this is not by the air of filter by the air of suction inlet, contains more dust, so on the ventilating duct attached to heat exchanger or cabinet, become the reason of dirt.In addition, pass through the air of suction inlet owing to fully accept to use the effect of the filter cleaning room air of air conditioner, so weakened the catharsis of room air.Therefore, wish to get rid of as much as possible the suction of not passing through the air of suction inlet, but owing to the restriction in the aforesaid manufacturing is difficult to eradicate.

On the other hand, owing to be easy to the machine of installing an air-conditioner maintenance operation afterwards, and can keep initial performance and undertake the important function that alleviates the load of environment, so the strong request part relevant with the maintenance operation just can freely be loaded and unloaded without instrument.Therefore, make the maintenance operation that the instrument that does not use front panel just takeoffs and carries out inside.This occasion is loaded and unloaded easily in order to make the big front panel of area, can not make front panel and main body side driving fit, and main body side between produce the gap.The air by suction inlet is not inhaled into from this gap, has promoted inner dirt.

Simplicity when responding above-mentioned maintenance operation and suppress these two opposite requirements of adaptation that air leaks, the present invention is provided with packaged unit 333 between plate 25 and the heat exchanger 33 in front.Packaged unit 333 in dish 35 and the fastening of uncovering, with lead-frame 234 and the fastening of top driving fit at the cleaning agency of filter 231 described later, almost completely interdicts the leakage air that enters into heat exchanger 33 from the front with the bottom driving fit.Thus, the leakage air that flows directly in the heat exchanger 33 by filter 231 does not tail off, and has alleviated the dirt in heat exchanger 33 or the indoor set 2, can not weaken the air cleaning effect of filter 231 yet.

At this moment, though in order to load and unload freely fastening front panel 25 and cover 335 and hole etc. is set on packaged unit 333, but the gap that produces between the main body of the area in these holes and plate and indoor set 2 is in front compared much smaller, and, because the fastening portion of front panel 25 and cover 335 is entrenched in these holes, so the area in gap further reduces, therefore the air from these holes leaks considerably less.But preferably the area in these holes is reduced to required minimum, should vainly not leave required above big hole.

Use Fig. 5~Fig. 7 that the handling operation of a series of air cleanness filter is described.Fig. 6 is the loading and unloading key diagram of the cover of indoor set.Fig. 7 is the replacing job description figure of the air cleanness filter of indoor set, (b) is the stereogram of the disposal box of cleaning agency, (c) is the stereogram of the cleaning of cleaning agency with hairbrush.

In the occasion that air cleanness filter 331 is installed, at first, front panel 25 is opened as shown in Figure 5, catch the handling knob of cover 335 of exposing to pull to the front, unload lower cover member 335 as shown in Figure 6.Insert air cleanness filter 331 as shown in Figure 7 and air cleanness filter 331 is installed in the 333b of folding and unfolding portion from opening 333a.Its occasion of cleaning with opposite order dismounting air cleanness filter 331, is returned the 333b of folding and unfolding portion after washing and the drying.Like this, needn't tool using just can carry out the cleaning work of air cleanness filter 331, its frequency also be 2~3 years once about, so can not become user's burden.

Secondly, use Fig. 8 that the cleaning member of filter is described.Fig. 8 is the stereogram of the portion of filter cleaning mechanism of indoor set.

In an embodiment, at air suction inlet 27 plane filter 231 is set.Filter 231 engages with lead-frame 234, and lead-frame 234 possesses guide rail at rear portion and front portion, and possesses arranged side by side with anterior guide rail and the cardan shaft parallel with guide rail.

Cardan shaft has the polygon section, and axle is supported on the bearing that is arranged on the lead-frame 234, by being installed on the gear on the end that connects a side bearing, be fixed on lead-frame 234 on move and be connected with motor.Lax screw rod, the balladeur train of being equipped with on cardan shaft, screw rod and the tooth bar engagement that is parallel to cardan shaft that is arranged on the lead-frame 234.

Between balladeur train and guide rail, cross over filter 231 suspension hairbrush carriages 262, the cleaning hairbrush 267 that scavenge filter 231 is cleared away is installed on hairbrush carriage 262.

So, move with the motor rotation by making, thus cardan shaft, screw rod rotation, and screw rod moves along the corresponding direction that moves with the direction of rotation of motor to the left and right of tooth bar, and balladeur train is moved.Thus, cleaning with hairbrush 267 with filter 231 sliding-contacts in clean and move, the dust on the filter 231 is swept to is cleared away on the usefulness hairbrush 267, and move it the dust removal brush 270 of lead-frame 234 left parts.

Cleaning is used soft hair with the hair of hairbrush 267, be chosen to be suitable with the rigidity of filter 231 identically, so that will clear away with hairbrush 267 by being pressed on 231 of the filters and when mobile, filter 231 also can be guaranteed the suitable amount of repetition because of cleaning after being out of shape with pushing of hairbrush 267.Here, the amount of repetition be meant hypothesis cleaning with the hair of hairbrush 267 the length during indeformable but straight condition from filter plane to high-quality green tea.

Like this, because cleaning is used furs with hairbrush 267, institute only gets final product from a side scavenge filter 231 so that the power that filter 231 is out of shape diminishes, even also can not sweep off dust on the filter 231 from rear side supporting filter 231.Therefore, only the driving mechanism when a side of filter 231 is provided with the utilization cleaning with hairbrush 267 scavenge filters 231 gets final product, and driving mechanism is simplified significantly.

Secondly, use Fig. 9 that the structure and the action of cleaning agency are described.Fig. 9 be cleaning agency trap debris sweep off the action details drawing.

Has when cleaning action cleaning on filter 231 right-hand with the standby portion 238 of hairbrush 267 standbies.Standby portion 238 is provided with the depressed part F234f that the face than filter falls in shown in the F portion of Fig. 9, with filter 231 sliding-contacts the time shown in the E portion of Fig. 9, crooked cleaning open and return to straight condition shown in the F portion of Fig. 9 with hairbrush 267.

Therefore, cleaning is used during hairbrush 267 standbies, can not act on the power of cleaning with hairbrush 267 bendings that makes, and does not have crooked character on clearing away with hairbrush 267.In addition, the mesh that is filtered device 231 on filter 231 when mobile reverses and the distortion of the high-quality green tea that produces is also restored, put in order.

Therefore, cleaning state and filter 231 sliding-contacts of hairbrush 267 in each cleaning action with regulation, the cleaning action is stable, can bring into play desired cleaning performance.Have again, in standby portion 238, because cleaning uses the high-quality green tea of hairbrush 267 by opening, so compare with the occasion of the state that does not have depressed part F234f and high-quality green tea bending, eliminated cleaning to begin turning high-quality green tea disorder when mobile and applied the situation of unnecessary power with hairbrush 267, so can not apply unnecessary load to the driving mechanism of clearing away with hairbrush 267, the reliability of driving mechanism improves.

In addition, high-quality green tea is not applied unnecessary power when overturning with hairbrush 267,, can prolong and change the interval that hairbrush 267 is used in cleaning so be difficult to produce the deterioration of high-quality green tea owing to cleaning.In addition, at filter 231 with remove brush and be provided with depressed part C234c between 271.The degree of depth of depressed part C234c is made and is being removed the turned position of removing brush 271 of brush finish 27a when cleaning is exposed maximum with hairbrush 267 sides, remove the top, top of brush finish 271a and filter 231 faces about equally, thereby make the scope that makes cleaning arrive the bottom of depressed part C234c with the high-quality green tea of hairbrush 267.

By making this structure, need not make cleaning with hairbrush 267 be deformed to when sweeping filter 231 above just can make to clear away to remove with hairbrush 267 sliding-contacts brush 271, can not give and excessive distortion with hairbrush 271, can suppress to clear away deterioration with hairbrush 271 to cleaning.In addition, can make and remove brush 271 and only expose with the degree of depth of depressed part C234c with hairbrush 267 sides to cleaning and measure accordingly, the area of removing brush finish 271a becomes greatly, the dust 236 that can play stably remove performance.

Cleaning when action, it is mobile like that shown in the D portion of Fig. 9 that the running driving mechanism makes the F portion as Fig. 9 be shown in the cleaning usefulness hairbrush 267 of standby portion 238 standbies, thereby sweep filter 231.At this moment, cleaning is gradually making the high-quality green tea diastrophic filter simultaneously more given prominence to 231 from the open state of depressed part F234f by inclination F233f with the high-quality green tea of hairbrush 267, and with filter 231 sliding-contact securely.

Cleaning is swept filter 231 with hairbrush 267 when the direction to dust removal brush 270 moves, sweep dust dust 236.The cleaning of sweeping of filter 231 of being through with arrives the C portion position of Fig. 9 with hairbrush 267 with the dust of sweeping 236, distortion at the open a little high-quality green tea of depressed part C234c, and arrive dust removal brush 270, and remove brush finish 271a and dust 236 reprinted sliding-contact the time effectively and remove brush 271.

Mark 268 is hairbrush pressing plates, is arranged on the one or both sides of hairbrush, and the hairbrush front end during to the cleaning action is given and suitable elasticity, keeps the performance of sweeping the dust dust well and prevented to be made hairbrush from the root bending to the root of hairbrush with the distortion of transition.In a side occasion of hairbrush pressing plate is set, for the above reasons, one side of the high-quality green tea distortion of hairbrush is advisable when being arranged on the cleaning action.In addition, if be arranged on both sides, then the distortion of hairbrush high-quality green tea is roughly the same when the cleaning action and during return action, can prevent that hairbrush from becoming inhomogeneous easily.

Hairbrush carriage 262 stops when bar projection 269 1 is crossed dwang 271c, and this position becomes the depressed part A234a more recessed than above-mentioned depressed part C234c.At depressed part A234a, the depressed part F234f of the high-quality green tea of cleaning usefulness hairbrush 267 and above-mentioned standby portion 238 is similarly open, and begins to move to filter 231 directions after the upset.Thus, cleaning stop with hairbrush 267 during, cleaning usefulness hairbrush 267 from the recovering state of bending to straight condition.The mesh that is filtered device 231 on filter 231 when having moved in addition, reverses and the distortion of the high-quality green tea that produces is also restored, put in order.
