Below, describe one embodiment of the present of invention with reference to the accompanying drawings.Fig. 1 is illustrated in the indoor set that inside has negative oxygen ion generator.The framework of the indoor set 1 of air conditioner constitutes with decorative panel 2.Formed the air entry 2a of room air on decorative panel 2,2a is adjacent with air entry, has arranged the heat exchanger 3 for room air refrigeration and heating, is made from air entry 2a inhaled air by fan 4 and passes through heat exchanger 3, is sent to indoor from exhaust outlet 5.Fan 4 uses DC fan in the present embodiment.

The control air supply direction control panel of air supply direction up and down 6 is up or down arranged on exhaust outlet 5, and the air of sending from DC fan 4 in order to control is flowing of direction up and down.In addition, also control the left and right directions (horizontal direction) of the air of sending from DC fan 4 with left and right directions control panel 7.In addition, the back side in indoor set inside is provided with rear side housing 8, to constitute the inner space.

In the present embodiment, negative oxygen ion generator 9 has been arranged in exhaust outlet 5 the place aheads.In addition; at the sparking electrode 9a that has also suitably represented to be arranged on the generation negative oxygen ion on the negative oxygen ion generator 9 on Fig. 1～Fig. 9; do not allow hand touch the sparking electrode over cap 9b of sparking electrode 9a, and be arranged on electrode cap narrow slit 9c on the electrode protection lid 9b etc.

In the present embodiment, on the backboard 11 of air conditioner, form opening portion 11a, and between the opening portion 11a at this back side and rear side housing 8, be provided with the pipeline 10 of maintenance usefulness.In addition, the pipeline in the wall 12 is inserted in the through hole that forms on the wall of the installation indoor set relative with backside openings part 11a, and link to each other with the pipeline 10 of maintenance usefulness.

Like this, from outdoor cleaning sparking electrode 9a the time, can be the bar of cleaning usefulness and brush 14 (Fig. 2) passes

pipeline

12 and 10 from the outside inside.

In the present embodiment, as shown in Figure 1, because the sparking electrode 9a of the negative oxygen ion generator from outdoor to air conditioner is communicated with a straight through hole (pipeline 12 and 10), if indoor dust is attached on the sparking electrode 9a, when its performance is descended, just can ask the maintainer to come, brush 14 grades of cleaning sparking electrode 9a are put in the pipeline 10, clean.

At this moment,, also can directly clean, stay the people so needn't discuss in advance to be in from outdoor even there is no one at home, in addition, owing to the maintainer can overhaul in any time that he thinks fit, so also improved the efficient of maintenance activity.For this reason, preferably the direction towards easy cleaning such as installation direction of sparking electrode.

Fig. 3 is exactly for the ease of be built in the sparking electrode parts 9 the indoor set 1 from outdoor cleaning, utilize the mode of the socket 15 that can freely insert and extract, the insertion of the part of the connection power supply of sparking electrode parts 9 and the direction of extracting, be set in pipeline 12 in the wall and maintenance axis direction with pipeline 10.

As shown in Figure 4, the part 16 (crocodile mouth) that can bite plug 15a (sparking electrode one side) is contained on the front end of the rod that inserts from pipeline 10, at first, the plug 15a that sparking electrode 9a is housed is pulled up from (power supply one side) socket 15b, make it by after the pipeline 10 that overhauls usefulness, clean in the outdoor sparking electrode 9a that directly is clear that, then, the pipeline 10 by maintenance usefulness installs on the socket 15b again again.

In addition; this moment as shown in Figure 4; front end by making sparking electrode 9a is towards the back side of indoor set; and then the narrow slit 15a in the plug 15 of double as electrode protection lid is on the position of above-below direction; then be easy to be inserted into and extract, and, because plug portion 15 does not hinder the cooling air stream of discharging from DC fan 4; it can be by becoming sparking electrode the narrow slit 15a of plug 15 of over cap flow out, thereby many negative oxygen ions after overdischarge just can be arranged in the air-flow.

The example of another kind of negative oxygen ion generator has been installed in expression among Fig. 5, Fig. 6 (the section A-A of Fig. 5) and Fig. 7.For the ease of be contained in the discharge electrode part 9 of indoor set 1 inside from outdoor cleaning, discharge electrode part 9 that produces negative oxygen ion and the outdoor opening portion 12a on the wall interior conduit 12 are coupled together with track 17.Discharge electrode part 9 is contained on the sliding part 19, so that discharge electrode part 9 can move freely on track 17.

Therefore, when from outdoor cleaning discharge electrode part 9,, just pull out, just can disassemble sparking electrode 9a from outdoor at an easy rate to the wall outside direction by backward the sliding part 19 that discharge electrode part 9 is housed.Like this, just can in the very short time, finish cleaning (cleaning) work reliably.In addition, after the cleaning, again it is put back on the original position of track 17, like this,, do not need to enter within doors, also can clean sparking electrode 9a reliably even there is no one at home.

Fig. 8 is another example that negative oxygen ion generator is installed, the same with the example of front, for the ease of be installed in the discharge electrode part 9 of indoor set 1 inside from outdoor cleaning, the electric wire of discharge electrode part 9 has used flexible cord 20, so the discharge electrode part 9 of indoor set inside just can freely rearward move.Therefore, discharge electrode part 9 after standing part disassembles, is taken out by pipeline 10 opening 12a from behind behind, do not taking electric wire apart, allow it also connect under the superincumbent situation, seeing cleaning discharge electrode part 9 with eyes at an easy rate.

Fig. 9 is another example that negative oxygen ion generator is installed.In order to clean discharge electrode part 9 easily, negative oxygen ion generating device (discharge electrode part 9) is installed on the front end 21a of pole 21, again pole 21 is inserted by the opening (pipeline 12) that is arranged on the wall that indoor set 1 is installed, just can be arranged on discharge electrode part 9 in the cold air of being discharged by DC fan 4.

The other end 21b of pole 21 is screwed and is being provided with near the hole of opening on the wall of indoor set, unload screw, just can freely pull out outdoor negative oxygen ion generating device 9, perhaps inject in the indoor set, thereby can see with eyes easily outdoor, clean negative oxygen ion transmitting apparatus 9 reliably.

Below, with reference to each later accompanying drawing of Figure 10, illustrate from the example of the maintenances such as the outside filter of changing indoor set of wall of indoor set that air conditioner is set.In this example, air entry 2a one side that is installed in indoor set 1, remove filter 22 that house dust uses and do and become band, the one end can be wound on the mandrel 22a, and the other end can be wound on another mandrel 22b.By means of this structure, the dirty rolled-up while of filtering surface, can spread out new filtering surface, in case of necessity, can also oppositely reel.

In addition, because the mandrel at two ends can take out by the left and right mandrel conveying end of being opened 25 and 26, and after inserting, become the structure that has assembled again on the back side of indoor set and wall, so, in the moment of batching filtering surface to the end, when the maintainer wants scavenge filter 22, unclamping just the filter that winds up, connecting mandrel 22b takes out together, the filter that winds up is pulled out from mandrel 22b, fall to be attached to top dust, clean with brush and so on brush.

The filter of cleaning after being over is wound on the original mandrel 22b again, then, the last filtering surface of filter is wound on the mandrel 22a, again mandrel 22a taken out the wall outside, dirt filtering surface pull out and clean.When cleaning is over, be wound up into again on the mandrel 22a, return to original state.Then, suitably rotate two mandrels, fix on the initial filtering surface.Like this, filter just can continue to have used., because these operations can be finished outdoor,, also can carry out the maintenance work of scavenge filter even there is no one at home.

In addition, the mounting structure of each mandrel 22a, 22b is shown in Figure 11 (the A-A view of Figure 10) and Figure 12 (the B-B section of Figure 10), the depth D u of the length L u of upper axis core and bearing 22c is long than the length L d of lower shaft core, and also the length L d than lower shaft core is big for the gap Su of upper axis bearing surface and the upper end of filter 22.

Like this, the filter 22 that is wound on the mandrel is moved upward, again them to drawing at one's side, the bottom mandrel is disassembled from the hole of lower bearing 22d, just can take out the mandrel of the filter 22 of reeling.Filter is spread out, remove after the dirt, wind up again, on the contrary, earlier the top mandrel is inserted in the hole of upper bearing 22c, and then the bottom mandrel is turned back in the hole of lower bearing 22d, reinstalled mandrel, 22 tensions of lax filter, be wound on each root mandrel again, just can be arranged on the filter 22 of tensioning on the air entry 2a.

Below, utilize Figure 13 and Figure 14 that another example of the suction side filter of cleaning indoor set is described.Shown in Figure 13 (A), the filter 22 in this example is made the shape of a strap.Shown in Figure 13 (B), be provided with hook part 22c at the left end of filter, be provided with the hook hole 22d that accepts another piece filter left end hook at the right-hand member of filter.

Shown in Figure 13 (A), when factory state, filter 22 has been installed in indoor set,, has been provided with respectively in the left and right sides from front that filter is housed up to filter 22 spatial accommodations at the back side of indoor set in order also to clean in use by black filter 22 from outdoor.In addition, on the wall 13 that indoor set is installed, also opened opening 25,26 in the face of above-mentioned spatial accommodation.

Shown in Figure 13 (B), in this structure, when the left of filter 22 on figure drawn, suction face just moved.At this moment, be ready to a new filter again, the hook portions 22c of the new filter 22 shown in the right side among the figure be hooked among the hook hole 22d of old filter (in use black filter 22).

Like this, along with pulling out old filter (left side), new filter (right side) has just drawn in.When the hook hole 22d on the old filter when opening 26 pulls out, new filter has just covered suction face, just can be replaced by the new filter 22 that does not have dust to adhere to.

In addition, shown in Figure 14 (A), also can prepare the filter 22 of new costliness in addition, and the ribbon (belt 32) that uses two ends to be respectively equipped with hook 32c and hook hole 32d replaces new filter 22.In the time will cleaning the filter 22 that is now using, before pulling out, earlier the hook 32c of belt 32 is hooked among the hook hole 32d of filter 22, only filter 22 is pulled out then, cleaning is over, and belt 32 is retracted, so filter 22 just has been in again on the position of suction face of indoor set again, like this, also can obtain same effect.

In addition, shown in Figure 14 (B), can only prepare the frame 33 of filter 22, replace belt 32.Be connected on the filter 22 with this frame 33, also can obtain same effect.Because these methods can both only be changed in an outdoor side, thereby identical with above-described example, overhaul activity at home when can have no talent.

Below, Figure 15 represents an example of the mounting structure of indoor set of the present invention.In the present embodiment, expression to be indoor set 1 be installed in example on the exterior wall 28 by installing component 27.On the backboard 11 that constitutes indoor set 1, offered the opening 11a of maintenance usefulness, so that the part that can need to change is changed from the part of an outdoor side to the indoor set 1 of air conditioner.And, on the installing component 27 that indoor set 1 is installed, also offered opening 27a over against above-mentioned opening 11a.Further, on the exterior wall 28 of fixed installation parts 27, also over against same position on offered and led to outdoor through hole 28a.Like this, just can carry out the dismounting and the installation of part, carry out various maintenance from outdoor from the opening 28a of exterior wall 28.

Figure 16 is the example that lid 23 is installed on the wall coil road 12 outside.For indoor set 1 from outdoor cleaning air conditioner, when pipeline 12 is set on wall within the walls, invade indoor in order to prevent wind and rain from the opening portion of pipeline 12, be provided with the lid 23 of shutoff opening portion, so that outside the repair time of cleaning and so on, can not be from the external touch to the discharge electrode part 9, for example, unlikely generation is the such thing of harassing and wrecking deliberately.

In addition, expression has been installed and has been locked 24 example among Figure 17 and Figure 18, make where necessary between outside, lid 23 can not be unloaded down.The structure of lock 24 can illustrate with Figure 17 and Figure 18.

As shown in figure 17, be provided with block 23a in the inboard of lid 23, the below of its leading section forms hook-type (lock), when the front end 23b of block 23a contact ratchet 29, because ratchet 29 is rotating shaft with fulcrum 29a, compression and its be the helical spring 30 of end in contact down, can temporarily subdue block.After the front end 23b of block 23a passes through,,, lid do not gone back so just drawing because helical spring elastic force embeds among the hook portions 23b ratchet 29.That is, pinned with lock handle lid 23.

Then, as shown in figure 18, in the time will unblanking, unclamp the screw 31 that pushes away on one side downwards from below compression spring 30 on one side, this moment, helical spring 30 also descended, because the hook portions 23b disengaging of ratchet 29 and block 23a, unloaded down so just can pull out lid 23 from the outside.

Therefore,, man-hour is arranged at home, just can screw down indoor screw 31, lock is opened as long as know that in advance the maintainer will come.When going home Deng the family members, maintenance is finished, and screw 31 is twisted go back again, and helical spring is risen, and just can make ratchet 29 pin block 23a effectively, just can make the lid 23 can not be from external opening.

In addition, owing to added lid, outdoor air can't be invaded indoor, just can not make the decrease in efficiency of air conditioner.Even if the powerful wind that typhoon and so on is arranged to opening portion, also can not influence the air-flow of indoor set exhaust, can stably discharge air-flow.

Below, the effect of embodiments of the invention is described.Describe in detail as above,, the outside of the wall of installation indoor set is communicated to always owing to used the through hole (pipeline) that is straight line, for example, produce the discharge electrode part of negative oxygen ion, so, even outdoor, also can clean discharge electrode part.

In addition; when discharge electrode part is installed; discharge electrode part is made female type; the direction that pulls the plug out of the socket is the direction towards the through hole at the indoor set back side; and on the over cap direction of narrow slit be upper and lower to; so can utilize the bite bar of discharge electrode part (band crocodile mouth) at an easy rate, discharge electrode part is pulled out from the through hole insertion at the back side.And, owing to do not hinder the air stream that flows to sparking electrode, be convenient to flowing of a large amount of air, can make in the air of discharge and contain a large amount of negative oxygen ions.

In addition, owing to the air openings of the discharge electrode part of indoor set inside and perforation pipeline is coupled together between partly with track, and sparking electrode is loaded on this track, can move freely, so can be from outdoor pulling out after the discharge electrode part dismounting, can be clear that with the naked eye and to clean discharge electrode part reliably under the situation of discharge electrode part.

In another example, make the power line of discharge electrode part owing to adopt flexible material, make indoor set inside sparking electrode freely the opening portion to the back side move, so do not need to cut off the electricity supply and the operation that is connected power supply, can carry out service work easily, improve efficiency of operation.

Further, owing to negative oxygen ion generator has been installed at the front end of pole, and the other end of pole is screwed outside near the wall opening of indoor set is set the wall, as long as unclamp hold-down screw, just can pull out cleaning to negative oxygen ion generator from the outside.Like this, even there is no one at home, the maintainer also can see with eyes and clean, overhaul reliably.

In addition, owing to lid is installed at the opening portion of outdoor wall, and lock has been installed, just needn't worry the wind and rain intrusion, even wind-force is very big, also can not invade in the indoor set by the pipeline that connects, so can not upset exhaust airstream, can obtain stable duty.In addition, because lock has been installed, when there is no need, can not also have the effect of delinquency prevention from the outdoor parts such as discharge electrode part that touch.

In addition, part with filter of needs maintenances and so on, all be arranged to carry out from the back side installation and removal operation of part, just can overhaul from the back side of indoor set, and, owing on the installing plate of the back side of indoor set, indoor set and wall, be provided with through hole, even unmanned in the family, also can overhaul, can overhaul activity expeditiously.

More than all, the maintenance to negative oxygen ion generator and filter mainly has been described, according to the present invention, other electric parts of indoor set inside also can be used as the object of maintenance.For example, also can be used as the object of maintenance to the air of indoor discharge from indoor set.Attempt an example, for the parts of additional cypress fragrance in the air of discharging, also can be the same with negative oxygen ion generator, carry out regular replacing at home when also can have no talent from the outside.

Equally, ozone generator, deodorant, bactericide or the like for the inside of indoor set, also can be provided with from the outside, service work such as replacing.In addition, for example, can insert a dust catcher that front end is very thin,, can carry out regular cleaning and maintenance, just can make indoor set often remain on clean state in order to dust of sopping up indoor set inside or the like from the outside.

Below, in Figure 19, represented a kind of comparative example with indoor set of negative oxygen ion generator.The sparking electrode 109 of negative oxygen ion generator is in order to sneak into negative oxygen ion in entering indoor air, to be arranged on by DC fan 104 air-supply backs by in the air-flow of heat exchanger 103.

If negative oxygen ion generator (sparking electrode 109) is by contamination by dust, when cleaning, can open the trim 102 of front, pull down air supply direction control panel 106 and 107, again the front end of negative oxygen ion generator (sparking electrode 109) is removed, after cleaning, installing on the original position.

; because negative oxygen ion generator (sparking electrode 109) is the part through high-precision processing; must come by the maintainer who repairs household electrical appliance; the lid 102 of indoor set is disassembled; air supply direction control panel 106 and 107 is also disassembled, clean at taking-up sparking electrode 109 then.Like this, in the time that the maintainer comes, must the people be arranged family, very inconvenient.In addition, can't clean in the optimal time, negative oxygen ion generator mostly will turn round under the state of its poor efficiency.

As mentioned above, according to the present invention, owing to be provided for overhauling the opening portion of maintenance at the back side of indoor set, and through hole by on the wall of above-mentioned opening and installation indoor set, forming, can be from the outside indoor set inner body be changed and maintenance maintenance work such as cleaning, so,, also can regularly overhaul maintenance work at home even when having no talent.
