The specific embodiment
Below, the air regulator of use description of drawings one embodiment of the present of invention.
At first, use the overall structure of the air regulator 1 of Fig. 1～3 explanation the present embodiment.Fig. 1 is the structure chart of the air regulator of the present embodiment, and Fig. 2 is the escutcheon 23 of indoor set 2 of dismounting Fig. 1 and the stereogram seen from left, and Fig. 3 is the side sectional block diagram of the indoor set 2 of Fig. 1.
In Fig. 1, air regulator 1 use connecting pipe 8 connects indoor set 2 and off-premises station 6 consists of, the air in conditioning chamber.Be equipped with on the cabinet 21 of indoor set 2 DC fan 311, filter 231,231 ', heat exchanger 33, the basic inner structural members such as dish 35, up-down wind direction board 291, left and right wind direction board 295 uncover.And the basic inner structural members such as DC fan 311 grades that is arranged on cabinet 21 inboards is enclosed in indoor set 2 by escutcheon 23 is installed.In the front of escutcheon 23, front panel 25 is installed.The below of plate 25 disposes the display part 397 that shows operational situation and the light accepting part 396 that receives from the ultrared operation signal of independent in addition remote controller 5 in front.
On indoor set 2, be provided with the air suction inlet 27 that sucks room air and the Air blowing mouth 29 that blows out the air that regulates humiture at upper-lower position.And it constitutes, the blow flow that blows out from DC fan 311 is flowed to have with the length width about equally of DC fan 311 blow air channel 290, with being configured in the left and right directions that blows the left and right wind direction board 295 deflection air-flows in 290 ways, air channel, recycling is arranged on the above-below direction of the up-down wind direction board 291 deflection air-flows on Air blowing mouth 29, and is blown into indoor.
The following Air blowing mouth 29 that is formed at escutcheon 23 and is communicated with the air channel 290 that blows of the inside on the cutting part that is configured in front panel 25.Two up-down wind direction boards 291 form the large curved surface continuous with the bottom surface of indoor set 2 with the blocking hidden air channel 290 that blows roughly.And up-down wind direction board 291 is to be located at turning cylinder on both ends as fulcrum, and the indication according to from remote controller 5 utilizes CD-ROM drive motor, rotates required angle and open Air blowing mouth 29 when air regulator turns round, and keep this state.When the air regulator running stops, controlling Air blowing mouth 29 it is closed.
In addition, the constituting of left and right wind direction board 295 to be located at turning cylinder on the bottom as fulcrum, can utilize not shown CD-ROM drive motor to rotate; According to rotating from the indication of remote controller 5 and keeping this state, make blow air be blown into the required direction of left and right.In addition, by sending indication from remote controller 5, up-down wind direction board 291, left and right wind direction board 295 are periodically swung, periodically carry blow air indoor on a large scale.
In addition, the movable platen 251 of suction side is by making CD-ROM drive motor rotation, thereby rotates take the turning cylinder that is located at the bottom as fulcrum.This movable platen 251 is controlled, make the front side air intake section 230 that opens when air regulator turns round ', also from front side air intake section 230 ' room air is sucked in indoor set, when air regulator stops, closing front side air intake section 230 '.
And, according to the indoor set 2 of the present embodiment, when stopping with up-down wind direction board 291 and the hidden air of movable platen 251 blow air channel 290 and front side air intake section 230 ' and with indoor coordination.Up-down wind direction board 291, left and right wind direction board 295 are rotated according to the indication from remote controller 5.Meanwhile, open movable platen 251 and from front side air intake section 230 ' and upside air intake section 230 suck room airs.Can the room air that suck be become cold wind or warm braw and blow out from above-mentioned Air blowing mouth 29 with the heat exchanger 33 of inside.
When this air regulator 1 of running, switch on power and remote controller 5, carry out the running of required cold air, dehumidifying, heating installation etc.
In the occasion of the runnings such as cold air, for room air being led to the heat exchanger 33 of the place ahead part of DC fan 311, as shown in Figure 3, make the movable platen 251 that consists of front panel 25 parts rotate and open.Make the front side air intake section 230 of room air by the escutcheon 23 of the inside of upside air intake section 230 and the movable platen 251 opened ' be passed to heat exchanger 33.
In a word, micro computer makes not shown CD-ROM drive motor work, and up-down wind direction board 291, left and right wind direction board 295 are turned to the blow out angle corresponding with the indication of remote controller 5.And micro computer makes the movable platen CD-ROM drive motor work of opening linkedly movable platen 251 with the action of above-mentioned up-down wind direction board 291.
Then, micro computer is controlled, make DC fan 311 rotation, from the air intake section 230,230 of upside and front side ' suck room air, this room air is become hot blast or cold wind with heat exchanger 33 or do not carry out heat exchange and blow out from Air blowing mouth 29.On the other hand, when shutting down, micro computer is controlled, and after DC fan 311 is stopped, making the CD-ROM drive motor counter-rotating of CD-ROM drive motor and the up-down wind direction board 291 of movable platen 251, returns to the state of closing.
The dish 35 that uncovers is configured in the below, bottom of the both sides, front and back of heat exchanger 33, accepts the condensate water that heat exchanger 33 produces when turning round with dehumidifying when cold air operation.The condensate water of accepting collection is discharged to outdoor by discharge line 37.
Thus, form the main air duct that makes the indoor air flows through regulating.That is, by the running of DC fan 311, room air sucks from air suction inlet 27, by filter 231,231 ', after carrying out heat exchange with heat exchanger 33, blow out to indoor from Air blowing mouth 29.
Then, use Fig. 4～Fig. 8 that filter 231 is described.Fig. 4 means the state diagram of the resin fibre net of filter having been carried out sputter processing.Fig. 5 is that the resin fibre net to filter has carried out sputter processing, then carries out the key diagram of the state of calendering processing.Fig. 6 is the key diagram of the proper range of filter parameter.Fig. 7 means the curve map of the relation of the wire diameter of filter and mesh.The antibacterial tests result of the resin fibre net of sputter that Fig. 8 is applying of filter processing.
If adhere to a lot of dust on filter 231, descend because the resistance that becomes Air Flow makes the heat exchange performance of heat exchanger 33, so the ability of freeze cycle descends.Therefore, need scavenge filter 231 termly.The cleaning of filter 231 after using deduster etc. to remove dust, then is dipped in upper washing agent etc. with sponge or soft brush etc., and the dust or the dirt that are not sopped up are washed off.
Generally, filter 231 with block circular air regulator 1 positive and above air intake section 230,230 ' whole modes install, because needs are cleaned termly, the user frequently carries out handling operation.At this moment, make filter slide to load and unload along the mounting guide rail to air regulator 1.Therefore, the operation in order easily to load and unload with less power the time, even and repeated deformation can not rupture yet, filter frame 232, resin fibre net 231a need to be used the resin formings such as PP, PET, ABS.
In addition, the installed surface of resin fibre net 231a to filter frame 232, also the inspiratory airflow of room air is arranged on the either side in upstream side, downstream relatively.But, as mentioned above, in the past when loading and unloading for the cleaning of carrying out filter 231, because the surface of filter 231 contacts with guide rail and easily damage, therefore filter frame 232 is arranged on the upstream side of the inspiratory airflow of room air, thereby has prevented the damage of resin fibre net 231a.
In addition, the net of existing filter 231 is the surfaces of having exposed the resins such as PP, PET, ABS.The forming method that consists of the net of this filter 231 is that the resin that will melt penetrates from nozzle, and the method for cooling curing.Therefore, the net surface that has exposed resin seems smoothly but a lot of pores.Because the smog of swim aerial dust or cigarette etc. is attached on these pores, and enter into pore, even therefore clean termly filter 231, the dirts such as dust that enter into pore also are difficult to remove.
In addition, with the net that resin fibre is made, its wire diameter is very thin, easily damages during wiping.Therefore, need to clean to remove dust with the hairbrush of softness.In addition, in recent years, the cleaning purpose improves, and sells the instrument that hand mop etc. can clean easily, has occurred using the hand mop promptly to wipe the demand of dirt.And, develop the cleaning agency that automatic sucking is attached to the dirt on filter.The attraction of this cleaning agency with the cleaning ground dust catcher more very a little less than.With this weak attraction also need to make be attached to filter 231,231 ' on dirt peel off.Like this, require namely to use weak power scavenge filter 231 that the dirt that is attached on filter 231 is peeled off, and remove the filter 231 of dirt.
In addition, except this cleaning purpose, safe purpose is also improving, and the market that wherein has the antibiotic converted products of antibacterial functions also enlarges year by year.In recent years, the high sealing of following dwelling house becomes the easily living environment of breeding of bacterium gradually due to reasons such as the increase of moisture or hypoventilations.Living environment health in order to realize comfortable, the antibiotic demand of air regulator are also increasing.
The filter 231,231 of the present embodiment ' structure as shown in Figure 3, comprise resin fibre net 231a, 231a ' and be used for to support the filter frame 232,232 of fixing resin fleece 231a '.The resin fibre net 231a of existing filter 231 is the surfaces of having exposed the resins such as PP, PET, ABS, due to the forming method of fiber be will fusing resin penetrate from nozzle, and the method for cooling curing, thereby the surface of having exposed resin seems a lot of pores is smoothly but arranged.Due to the dust that swims adhere to air in these holes in and the smog of cigarette etc. and in entering pore, though therefore obligingly scavenge filter 231 can not remove the dirts such as dust that enter into pore.
So; cutaway view according to resin fibre net 231a shown in Figure 4; make ionization in a vacuum the inert gases such as argon gas collisions on the metals such as stainless steel; form the sputter processing of film by the metallic that bullet is flown on resin fibre net 231a, form the metal protective film 231d such as stainless steel on resin fibre net 231a surface.Thus, by burying the pore on resin fibre net 231a surface, make the surface reach the level and smooth of nano-grade size, thus dust, dirt easily peel off, can prevent the infiltration of dirt.
At this, the face that applies sputter processing becomes the whole surface of resin fibre net 231a on the two sides in upstream, downstream and carries out sputter processing by the inspiratory airflow to relative room air, can further improve the fissility of dust, and can suppress the permeability of dirt, but, even only the upstream side of the inspiratory airflow of relative room air is processed also and can fully be obtained effect, can also realize cost degradation.
Again as shown in Figure 5, by on one side resin fibre net 231a being heated, carry out the calender processing of conquassation on one side with roll, can form planar portions in the intersection of longitudinal fiber 231b and horizontal fibers 231c, can easily peel off dust by further making resin fibre net 231a become level and smooth.
In addition, use resinous filter 231, the transfer of the resinous principle that causes when the cleaning thing of the soft resins such as sponge, brush or hand mop is contacted with resin fibre net 231a is for a long time partly stoped by stainless sputter, does not also cause the danger of the unfavorable conditions such as distortion of the coarse or high-quality green tea of 231 of filters.
At this, in Fig. 6 take the spacing of the line of resin fibre net 231a as transverse axis, take wire diameter as the longitudinal axis, the permissible range of expression aperture opening ratio, net intensity and mesh.Wire diameter is more thick more can improve net intensity.For suitably cleaning, more than net intensity is necessary for 8.5N/cm.If the net undercapacity, the distortion of filter 231 increases and produces the part that can not clean when cleaning, stays the not part of cleaning.
In addition, in order to ensure the pressure loss of air regulator 1, the aperture opening ratio of mesh on the whole area of resin fibre net 231a must be made more than 55%.This be because, the filter 231 that air regulator is used with the larger dust of the mesh of removing blocking heat-exchanger 33 as main purpose.Thereby, can not be set as the aperture opening ratio of the ability that reduces heat exchanger 33.In the occasion that has determined aperture opening ratio, if add the wire diameter of heavy wire, mesh (line of resin fibre net 231a and the distance of line, the size of mesh) enlarges, and large dust is passed through.Fig. 7 represents that this aperture opening ratio is 60% wire diameter and the relation of mesh.
Following content as can be known from Fig. 6 and Fig. 7.If if the certain overstriking wire diameter of aperture opening ratio, the intensity of resin fibre net 231a improves, but mesh becomes large, thereby large dust is passed through.On the contrary, if wire diameter attenuates, though mesh diminishes, the intensity of current resin fibre net 231a descends and the distortion of netting increases.
For example, if wire diameter surpasses 230 μ m, although the intensity of the resin fibre net 231a of filter 231 is good, mesh becomes 800 μ m and the arresting efficiency decline of dust.
Therefore, if the wire diameter of filter 231 is set as 230 μ m, the following dust of 800 μ m can be by the mesh of filter 231 in theory.But bad is, adheres to the above long fibre (broken line) of 800 μ m etc. on filter 231, although the broken line that adheres to also can adhere to and capture trickle dust, the above dust of 800 μ m is passed through.This be because, the distance between the fin of general heat exchanger 33 is the 1.2mm left and right, 800 μ m are sizes than the gap between fin 65% also large be 67% dust.Large like this dust becomes the reason of the mesh obstruction of heat exchanger 33 simultaneously by more difficult between 2 fin.So in the present embodiment, the mesh 765 μ m that will calculate with the wire diameter 220 μ m under a grade are as the upper limit of mesh.This be between fin distance 64%.
According to these contents, as resin fibre net 231a preferably the tensile strength of resin fibre net 231a be more than 8.5N/cm and aperture opening ratio is, mesh is below 765 μ m more than 55%.
The tensile strength of resin fibre net 231a is lower than 8.5N/cm, and the undercapacity of resin fibre net 231a is easily crooked and obstacle occurs in cleaning.Situation take the material of resin fibre net 231a as PET is as example, if it is shown in Fig. 6, suitable scope is the scope of the upside of A curve.In addition, the A curve moves up and down according to the material of resin fibre net 231a, roughly changes according to the tensile strength of material.
If aperture opening ratio is lower than 55%, the fluctuation of speed of the air-flow by resin fibre net 231a is large, and flowing resistance increases and undesirable.If suitable scope is shown in Fig. 6, it is the scope of the downside of B curve.
If mesh surpasses 765 μ m, be stuck in dust between the fin of heat exchanger 33 by filter 231 and improper.And, if mesh is large, when carrying out automatic cleaning, each root resin fibre cleaning thing is crossed it move stiffly, can not smoothly move, become the reason of noise or vibration, be not intended to make the dust on filter 231 to fall, around pollution.If suitable scope is shown in Fig. 6, it is the scope in the left side of C curve.
According to above content, the scope of suitable resin fibre net 231a becomes the zone of the use curve A of Fig. 6, B, C encirclement.Like this, net intensity is more than 8.5N/cm by making, mesh is below 765 μ m, aperture opening ratio is more than 55%, the good filter 231 of dedusting decontamination that a kind of suitable maintenance net intensity can be provided and large dust is passed through.
In addition, the processing of above-mentioned sputter processing and calender also can be applied on any of honeycomb knitmesh as the general structure of resin fibre net 231a, plain net.
At this, if the ojosa of the structure stereo weaving of resin fibre net 231a, though dust easily collision on resin fibre net 231a and the arresting efficiency of dust is high, due to unsmooth, namely use cleaning thing wiping dirt, dust also remains on concavo-convex negative area.
So, by the structure of filter 231 being made the plain weave structure, can make the surface of filter 231 become more level and smooth, easily clean.
In addition, the installed surface of the relative filter frame 232 of resin fibre net 231a, the inspiratory airflow of room air is arranged on the either side in upstream side, downstream relatively.But, filter 231 generally be mounted to block circular air regulator 1 positive and above air intake section 230,230 ' whole, because needs are regularly clean, the user frequently carries out handling operation.At this moment, along the mounting guide rail to air regulator 1, filter is loaded and unloaded slidably, but easily injured because the surface of filter 231 contacts with guide rail, therefore filter frame 232 is arranged on the upstream side of the inspiratory airflow of room air, thereby has prevented that resin fibre net 231a's is injured.
As shown in the Examples, carry out sputter processing by the slipper to the resin fibre net 231a, the 231a ' that contact with guide rail at least, can with metal protective film 231d protection, can prevent that resin fibre net 231a, 231a's ' is injured; Have again, owing to filter frame 232 can being configured in the downstream of the inspiratory airflow of room air, therefore do not exist on the face that dust adheres to by filter frame 232 cause concavo-convex, thereby the advantage of easily cleaning is arranged.
Fig. 8 be based on JISZ2801 regulation sputter processing stainless steel material resin fibre net 231a and do not carry out the result that the anti-microbial property of the resin fibre net 231a of sputter processing is estimated.This mensuration entrusts office of official to carry out.
According to this result as can be known, satisfy staphylococcus aureus and coliform as a reference value of antibacterial activity value more than 2.0, the effect of the breeding of the above-mentioned bacterium that can be inhibited.Thus; by being processed to form the metal coating mould 231d of stainless steel and can accessing antibacterial effect with sputter on the surface of resin fibre net 231a; thereby corresponding with the antibiotic demand in recent years safe purpose, a kind of air regulator for the living environment that realizes comfortable health can be provided.
Then, with reference to Fig. 9, Figure 10, DC fan 311 is described.Fig. 9 is the stereogram of DC fan 311, and Figure 10 is that comparison sheet is shown with the enlarged photograph without the DC fan surface of stainless sputter.
Generally, on the indoor set 2 of air regulator 1, the DC fan 311 that use is driven by air supply motor 313, to the result of time under the blade shape of blade 311a, the front end that popular is forms blade shape has more and more thinner so-called streamlined of circle and rear portion in order to reduce the air-supply noise.For this reason, the material of DC fan 311 is used synthetic resin, with method moulding such as ejection formations, obtained the blade 311a of required wing shape.
But the forming method that uses synthetic resin is owing to being that resin with fusing penetrates from nozzle, and through the method for cooling curing, so the exposing surface of resin seems a lot of pores are smoothly but arranged.Especially, DC fan 311 requires the thickness of blade 311a thin as far as possible on performance, and on the other hand due to High Rotation Speed, also requirement can be stood its centrifugal intensity of force.Therefore, add glass fibre etc. in moulding material and improve intensity.Like this, use products formed with the resin of the reinforcements such as glass fibre to produce in its surface concavo-convex, further increased pore.The dust that swims be attached to air in these pores in enters pore, and the dust that enters into pore can not remove easily.Like this, the dust that is attached on resin surface adheres to as mentioned above as time goes by more firmly, is deposited on DC fan 311, and the spore of fungi is disperseed or the generation stench.
In addition, DC fan 311 is due to the narrow blade 311a that is spaced a plurality of above-mentioned fairshaped wing shapes, therefore in its occasion of cleaning, wiping or cleaning blade 311a one by one, make blade 311a distortion or the possibility that fractures very large.And because DC fan 311 is laterally long shape, therefore in the operation when cleaning, the situation of distortion or distortion is also many, and in this occasion, the spin balancing of DC fan 311 is destroyed, produces very large vibration when turning round in the indoor set 2 of packing into.Like this, be difficult to carry out the cleaning of DC fan 311.
In the present embodiment, DC fan 311 is made resin and carry out stainless sputter.In sputter processing, as mentioned above because stainless particle pours in no direction, so form stainless thin layer in the all-round scope of the aerofoil of the blade 311a of DC fan 311.
As shown in figure 10, if apply stainless sputter, the pore on the surface of DC fan 311 is buried, by making concavo-convex tail off and the roughness on surface reduces to 2.8 μ m from 6.0 μ m, becomes level and smooth, thereby has reduced the pore that dust enters, and is difficult to adhere to.And the dust that with great difficulty enters into pore does not have other as the pore of social connections due to neighbouring yet, thus easily peel off with less power, and the air-flow that produces during by DC fan 311 rotation dispels.Like this, because the dust that adheres to is also peeled off rapidly, and the antibacterial action of stainless sputter protection mould, can suppress to be contained in the growth of fungi in dust etc., also can not elongate mycelia and be fixed on DC fan 311.And, owing to not piling up dust on the surface of DC fan 311, so kept the aerodynamic quality of DC fan 311, can not cause the increase of noise or the decline of air quantity yet.
Then, use Figure 11～Figure 14 that the scroll portion 289 in DC fan 311 downstreams is described.Figure 11 is the stereogram of cabinet, and Figure 12 is the scroll portion stereogram in DC fan air channel, and Figure 13 is that Figure 14 is the sectional view of indoor set from the exploded perspective view of the surperficial stainless steel parts in DC fan downstream.
As shown in figure 11, the scroll portion 289 in the downstream of DC fan 311 is continuously level and smooth downwards from the back edge 287 that is located on cabinet 21, and forms and can stably blow out air-flow from DC fan 311.This scroll portion 289 is along with the distance near back edge 287 and the blade 311a of DC fan 311 becomes near, even also be difficult to put in order to clean finger to be put into, if clean obstinately, makes the possibility of blade 311a distortion of DC fan 311 large.
In the present embodiment, scroll portion 289 is stressing folded corrosion resistant plate and is consisting of in the air channel one of continuous resin scroll portion downwards from back edge 287.This corrosion resistant plate adopt can absorb and resin scroll portion between thermal expansion difference installation constitution and many places are installed.Specifically being constructed as follows of this installation constitution namely, connects screw corrosion resistant plate and is screwed into resin scroll portion from the air channel side, inserts pad between corrosion resistant plate and screw head, and makes the diameter of the screw through hole of corrosion resistant plate larger than the external diameter of screw.Thus, even the variation of indoor temperature is arranged or because of the variation of the vent air temperature due to the running of cold air operation, heating installation, also can absorb the thermal expansion difference between corrosion resistant plate and resin scroll portion, can keep reliability and keep stationary state.
Utilize corrosion resistant plate scroll portion 289 to be made the even surface of metal, dust just is difficult to adhere to, and is also dispelled by the air-flow that causes when DC fan 311 rotates even adhered to.Like this, because the dust that adheres to is also peeled off rapidly, and stainless antibacterial action, can suppress to be contained in the growth of fungi in dust etc.And, because dust can not be deposited on the surface of scroll portion 289, so the resistance of ventilating duct can not increase, can keep the aerodynamic quality of DC fan 311, can not cause the increase of noise or the decline of air quantity yet.
In addition, cabinet 21 made resin and cabinet scroll portion 215 also is set on cabinet 21, overlapping the scroll portion 289 of corrosion resistant plate as shown in figure 12 at this.
Thus, because of complex-shaped, the ventilating duct surface of the cabinet 21 that forms by moulding resin covers with corrosion resistant plate, therefore produces and above-mentioned same effect.Have, cabinet 21 use corrosion resistant plates are strengthened again, so cabinet 21 becomes firm, easily carry, operate.And the inside of corrosion resistant plate also consists of with the resin of cabinet 21, so can utilize corrosion resistant plate to suppress heat conduction, the heat of waste reduces.In addition, at the back side of corrosion resistant plate, opening is not set, can spill between corrosion resistant plate and cabinet 21 so regulate air, can not have the situation of dewfall around gas leakage or wasted heat.
Then, use Figure 13～Figure 17 that the Air blowing mouth 29 of indoor set 2 is described.Figure 15 is the stereogram that the escutcheon 23 of dismounting indoor set 2 is seen from right, and Figure 16 is that uncovering of seeing from the below coiled 35 stereogram, and Figure 17 is that uncovering of seeing from the top coiled 35 stereogram.
Generally, the Air blowing mouth 29 of air regulator 1 owing to being the part that the user can see when using air regulator 1, therefore need to have the fluent and elegant shape of having used a lot of curves.The upper wall 290a that blows air channel 290 comprises: continuous from the leading edge 286 of DC fan 311, and be located at dish 35 the pallet lower surface 35b that uncovers of condensate water of the below of heat exchanger 33; And with the continuous ceiling face 290e of the opening top edge 290d of blow-off outlet.The lower wall 290b that blows air channel 290 comprises: vortex leading section 298 and support the wind direction board pedestal 294 etc. of left and right wind direction board 295.The left and right sidewall 290c, the 290c ' that blow air channel 290 are made of connecting portion 297, this connecting portion 297 is used for connecting by the pallet lower surface 35b of the dish 35 that uncovers and the upper wall 290a that blows the air channel and the wind direction board pedestal 294 that ceiling face 290e consists of, and has the shaft supporting part of up-down wind direction board 291.Be provided with up-down wind direction board 291, left and right wind direction board 295 and uncover the lower surface 35b of dish 35 and the middle interconnecting piece 297a of wind direction board pedestal 294 etc. in blowing air channel 290.Like this, except complex-shaped and, the dewfall due to the cold wind when alleviating by cold air operation due to needs, so the component parts of blow-off outlet is often used the resin injection moulding.
On the outside of the side of the sidewall 290c, the 290c ' that blow air channel 290, be provided with the installation portion 297b of the up-down wind direction board motor 111 that drives above-below direction plate 291.On ceiling face 290e and on the part of dish 35 the front that uncovers, be provided with the installation portion 35c that shows related electric component etc.
In the present embodiment, to the upper wall 290a (pallet lower surface 35b, ceiling face 290e), the lower wall 290b (vortex leading section 298, wind direction board pedestal 294) that blows the air channel that blow the air channel, the carrying out stainless sputter and form metal protective film with the resin parts that blows the part of facing in air channel 290 of left and right sidewall 290c, 290c ' (connecting portion 297) etc. that blow the air channel.
Thus, the pore on the surface by burying Air blowing mouth 29 becomes smoothly the surface, thereby the pore that dust enters is reduced sharply, and is difficult to adhere to.The dust that with great difficulty enters into pore does not have other as the pore of social connections due to neighbouring yet, thus easily peel off with less power, and the air-flow that produces during by DC fan 311 rotation dispels.Like this, because the dust that adheres to is also peeled off rapidly, and the antibacterial action of stainless sputter protection mould, can suppress to be contained in the growth of fungi in dust etc., also can not make mycelia elongate and be fixed on blow-off outlet.And, be not deposited in due to dust on the surface of blow-off outlet, can not increase so blow the resistance in air channel 290, kept the aerodynamic quality of DC fan 311, can not cause the increase of noise or the decline of air quantity yet.
At this, explanation need not apply the good part of stainless sputter.Generally, if with air regulator 1 ground connection, heat exchanger 33 becomes this earthing potential.This be because, because heat exchanger 33 component parts that is freeze cycle relates to from indoor set 2 to off-premises station 6, and connect with connecting pipe 8, therefore can easily contact with ground terminal, and can be with the conductor utilization of the connecting pipe 8 between connection indoor set 2 and off-premises station 6 as ground connection.In addition, the ground connection of electric component is generally the part made from the ground terminal same potential of main body.Like this, because the earthing potential of electric component is identical with the earthing potential of heat exchanger 33, so incomplete occasion of ground connection in the main body of air regulator 1, can think that the electrostatic potential of heat exchanger 33 rises because of stray capacitance, even contact with heat exchanger 33 in this occasion, also be in the state of the energising amount that is limited in being safe from danger.
But, in recent years, be widely used small-sized impulse motor as the driver that drives various parts, such as using the motor 111 that drives up-down wind direction board 291, the motor that the left and right part drives respectively left and right wind direction board 295, the motor of driving movable platen 251 etc.These all use the dc source of low pressure to drive, when insulation distance short, when for example its housing reaches the high potential of 100V unit, discharge between housing and internal terminal, its clutter easily transmits along lead-in wire, thereby be delivered on the electronic unit of controlling motor, might again cause in the little place of insulation distance discharge or cause misoperation.
In the present embodiment, the parts that consist of Air blowing mouth 29 do not have stainless sputter section on the face with the tray portion 35a that receives the condensate water that flows down from heat exchanger 33 or electric component installation portion.
Thus, even the incomplete occasion of ground connection in the main body of air regulator 1, the earthing potential of heat exchanger 33 stays in the level of the condensate water in tray portion 35a, and does not reach the state that blows air channel upper wall 290a of the pallet lower surface 35b that has applied stainless sputter.In addition, owing to not applying the stainless steel sputter on the installed surface of electric component, so can prevent that clutter from arriving on the housing of electric component etc., can prevent misoperation.
Therefore, even the contact application that catches has added the blow-off outlet of stainless sputter, also can avoid electrostatic shock.
Then, with reference to Figure 14, up-down wind direction board 291 is described.Up-down wind direction board 291 consists of the rear side that corrosion resistant plate 291a overlaps resin wind direction board 291b.Utilize corrosion resistant plate 291a to make wind direction board 291 become the even surface of metal, dust is difficult to adhere to, even the air-flow that has caused when having adhered to also by DC fan 311 rotation dispels.Like this, because the dust that adheres to is also peeled off rapidly, and stainless antibacterial action, thereby can suppress to be contained in the growth of fungi in dust etc.And, be not deposited in due to dust on the surface of up-down wind direction board 291, so the resistance of ventilating duct can not increase, can keep the aerodynamic quality of DC fan 311, can not cause the increase of noise or the decline of air quantity yet.
This corrosion resistant plate 291a adopt can absorb and resin wind direction board 291b between the structure of thermal expansion difference install.Specifically being constructed as follows of this installation constitution, namely, the side end of corrosion resistant plate 291a is bent into hook-shaped and installs in the mode of a side end of clamping resin wind direction board 291b, the end side of corrosion resistant plate 291a is turned back and is formed two-layerly, makes the structure of this leading section engaging of turning back near the end difference the end side that is formed at resin wind direction board 291b.Thus, even the variation of indoor temperature is arranged or because of the variation of the vent air temperature due to the running of cold air operation, heating installation, also can absorb the thermal expansion difference between corrosion resistant plate and resin scroll portion, can keep reliability and keep stationary state.
In addition, also can be on up-down wind direction board 291, left and right wind direction board 295 sputter stainless steel and form metal protective film.Thus, by the pore of burying up-down wind direction board 291, left and right wind direction board 295 surfaces, the surface is become smoothly, thereby the pore that dust enters is reduced sharply, and be difficult to adhere to.The dust that with great difficulty enters into pore does not have other as the pore of social connections due to neighbouring yet, thus easily peel off with less power, and the air-flow that produces during by DC fan 311 rotation dispels.Like this, because the dust that adheres to is also peeled off rapidly, and the antibacterial action of stainless sputter protection mould, thereby can suppress to be contained in the growth of fungi in dust etc., also can not elongate mycelia it is fixed on up-down wind direction board 291, left and right wind direction board 295.And, be not deposited in due to dust on the surface of up-down wind direction board 291, left and right wind direction board 295, so the resistance of the ventilating duct of up-down wind direction board 291, left and right wind direction board 295 can not increase, can keep the aerodynamic quality of DC fan 311, can not cause the increase of noise or the decline of air quantity yet.
