The specific embodiment
Below, with reference to drawing explanation embodiments of the present invention.
Fig. 1 represents the air conditioner in the embodiment of the present invention 1, represents the indoor set of ceiling embedded type air conditioner especially.
Air conditioner shown in Fig. 1 under the state of (downwards), is disposed at base frame 9 embeddings that contain heat exchanger 2 and pressure fan 3 in the ceiling in sucking grid 1 and blow-off outlet 4 faced chamber.During the refrigeration running, by sucking the air in grid 1 suction chamber, inhaled air cools off (adjusting temperature) and dehumidifying by the heat exchanger 2 that is disposed in from suction grid 1 to the ventilating duct of blow-off outlet 4, blow by pressure fans 3 such as cross-current fans, from blow-off outlet 4 with cold air to indoor discharge.In order to improve the efficient of heat exchange performance, and heat exchanger 2 has the structure that vertical slit is set, the water of dewfall drips on the drip tray (discharge dish) 6 along aluminium radiator fin in aluminium radiator fin and the formed space of slit on the heat exchanger 2, simultaneously, a part of water flows into drip tray 6 by water receiving conduit 5.The water that is accumulated in the drip tray 6 is finally discharged to the outside via discharge pipe (not shown) by draining pump (not shown).Draining pump is not operation all the time, signal is delivered to controller by switch but detect the water that accumulated in the drip tray 6 by switch (not shown) when arriving specified standard, and draining pump is moved by the control of controller.
In drip tray 6, be formed with the discharge outlet 7 that penetrates into an indoor side, on this discharge outlet 7, sealing bolt 8 be installed.Blow-off outlet 4 is formed at the bottom of drip tray 6, and near the of blow-off outlet 4 generally covered by heat-insulating materials such as expanded polystyrene (EPS)s.Discharge outlet 7 connects heat-insulating material and drip tray 6 both sides, and sealing bolt 8 is mounted freely on the discharge outlet 7 with the mode dismounting that is pressed into or screw is fixing.For example, its installation can be that sealing bolt 8 is fixed with the screw that discharge outlet 7 both sides are carved with screw thread, or the part that sealing bolt 8 inserts discharge outlet 7 is elastomer, makes sealing bolt 8 and discharge outlet 7 fluid-tight engagement.
And then sealing bolt 8 has can be to the antiseptic of drip tray 6 side strippings, owing to can easily carry out the exchange of antiseptic by the installation and removal of sealing bolt 8, so effect that can the long term maintenance antiseptic prevents the generation by assorted microbial foul smell.
Also have, so-called leachable antiseptic can be organic system antiseptic, inorganic series antibacterial agent, also can be their mixing antiseptic.As the organic system antiseptic, can use known 2,4,4 '-three chloro-2-dihydroxy diphenyl ethers, 2-P-aminobenzene-sulfonamide pyrimidine etc.And, in polypropylene, polyethylene, polystyrene, ABS resin etc., contain when having an appointment these antiseptics of 0.5～1%, form leachable antiseptic.And then, can be in resin disperse well in order to make antiseptic, can also in resin, sneak into oxides such as about 10～40% aluminium oxide, zinc oxide, hydroxide such as magnesium hydroxide, aluminium hydroxide, carbonate such as calcium carbonate, magnesium carbonate etc. as filler.
And preferred antimicrobial agents comprises at least a in zinc, copper, the silver, metal ion that can stripping stably has antibiotic property in discharge water.These metals can be processed into sheet material or wire rod shape and use, and also metal dust can be blended in the resin and use.The metal of wire rod or coiled type is processed in use, not only increases with the contact site of discharge water on drip tray 6, but also can use the amount of metal to increase, and this viewpoint from easy maintenance antibiotic property sees it is desirable.The direction of insertion that preferably is processed into the relative sealing bolt 8 of metal of wire rod or coiled type roughly is bent into the surface that the right angle is arranged on drip tray near sealing bolt, make metal wire rod or coil contact the stripping metal ion effectively with water.And, roughly be bent into the function that the right angle also has the brake that prevents that sealing bolt 8 from coming off.In order to be controlled at the stripping quantity in the discharge water, what employed metal can alloying, also can protection tunic or chemical treatment be set by rete at metallic surface.
And, constitute contacting with the metal littler than these metal ion tendencies by zinc or kirsite can stripping antiseptic the time, form internal cell by two kinds of metals, because zinc ion continues stripping in water easily, so can keep long-term antibiotic property.As than zinc or the little metal of kirsite ionization tendency, can use nickel, aluminium alloy, copper, silver, gold etc., particularly the processability of aluminium alloy and copper is good, uses easily.
Here, the concrete structure with reference to the sealing bolt 8 that is adopted in the air conditioner of Fig. 2～Fig. 4 to embodiment of the present invention 1 is illustrated.
Sealing bolt 8A shown in Figure 2 has rubber system body 10, forms recess 10a in the central authorities of drip tray 6 sides (top) of body 10, and dismounting freely is embedded with the antiseptic 11 of tabletization in recess 10a.There is no need to use binding agent etc. that sealing bolt body 10 and antiseptic 11 is integrated, by sealing bolt 8A can make in the tablet antimicrobial component at leisure stripping in discharge water.And, by sealing bolt 8A is taken off, can easily change antiseptic 11.
And, sealing bolt 8B shown in Figure 3 has rubber system body 10, central authorities in drip tray 6 sides (top) of body 10 form recess 10a, dismounting freely is embedded with cylindrical element 12 made of copper in recess 10a, simultaneously, an end of coiling into the coiled type member 13 of coiled type by galvanized iron wire etc. is clamped between cylindrical element 12 and the body 10.
As shown in Figure 3, since coiled type member 13 at one end be held on its with body 10 between before be bent into slightly 90 and spend, so insert coiled type members 13 from discharge outlet 7, when body 10 is installed on discharge outlet 7, coiled type member 13 can keep slightly level on the drip tray 6.And, because the zinc that coil surface is electroplated is bigger than the ionization tendency of copper, so can constantly zinc ion be emitted in discharge water.And then, because by sealing bolt 8B is extracted and anti-biotic material also can be taken off, so the replacing of coiled type member 13 also is easy to.
And sealing bolt 8C shown in Figure 4 has rubber system body 10, forms slit 10b at the central portion of drip tray 6 sides (top) of body 10, and metallic plates 14 such as copper coin are freely inserted in dismounting in slit 10b.

Fig. 5～Fig. 7 has represented the air conditioner in the embodiment of the present invention 2, has represented the indoor set of ceiling embedded type air conditioner especially.
The basic structure of the air conditioner in the basic structure of the air conditioner in the present embodiment and the embodiment 1 is identical substantially, but near the structure difference the drip tray 6, below difference is illustrated.
As shown in Figure 6, the dew of drip tray 6 flows into and is stranded in the water-accepting part 6a that drip tray 6 is set to concavity and forms, and the dew that accumulates is attracted from the lower end of draining pump 15, discharges to the outside via discharge pipe (not shown).Be provided with switch 16 in draining pump 15, when the water arrival specified standard of being accumulated among the water-accepting part 6a was above, switch 16 actions started draining pump 15, and the water that is accumulated among the water-accepting part 6a is discharged to the outside.
And, there is the lower portion that is positioned at draining pump 15 among the water-accepting part of the dew 6a to dispose metallic plates (ion discharge plate) such as kirsite plate accumulating.Simultaneously, be provided with metalworks 18 such as aluminium alloy at the 15a place, surface, water sucking mouth of draining pump 15.
Fig. 7 has represented the variation of structure shown in Figure 6, disposes ion and discharge plate 17 on the drip tray 6 below the float 20 that is positioned at switch 16, simultaneously, metalwork 18 is installed on float 20.
On the other hand, ion is discharged plate 17 so long as have than the big metal of metalwork 18 ionization tendencies, whatsoever the material of sample can, for example can use zinc, magnesium, titanium and their alloy.Zine plate, galvanized steel plain sheet, kirsite plate are the most cheap, and processability is good.Under the situation of using the kirsite plate, hope can use the high kirsite of corrosion resistance to form.If corrosion resistance is low, long-term use can make the zinc stripping, just can not reach and suppress vegetative effect.Suitable copper and the titanium composition kirsite of interpolation can improve its corrosion resistance in zinc, so preferred the employing.
And, preferably form chemical treatment by rete on the surface of kirsite plate.Chemical treatment by rete be utilize sulfuration in the solution or oxidation reaction and form on the surface of material thin sulfide or oxide tunicle by rete.Owing to can suppress the generation of excessive zinc oxide by this chemical treatment tunicle, be covered by granular metal oxide so can prevent the surface of kirsite plate.Thereby can make zinc stripping for a long time, the long-term vegetative effect of inhibition that keeps.Because chemical treatment is to utilize chemical reactions such as sulfuration or oxidation, so various methods are arranged.So long as do not change the stripping of Ionized tendency and inhibition ion, can adopt arbitrary method such as the processing of phosphoric acid tunicle, chromate processing.The phosphoric acid tunicle is handled simple, and the burden that earth environment is caused is less, so preferred the employing.
About the thickness of chemical treatment tunicle, because the stripping minimizing of metal ion, antibiotic property are descended, so the most suitable during the 1 μ m left and right sides.And then; for the breeding of the bacterium that suppresses to concentrate on kirsite plate surface, guarantee the long-term reliability of kirsite plate, and diaphragm preferably is set; because with on the side of metalwork opposite face diaphragm be not set can not damage antibacterial effect of kirsite plate, so be fit to.Can suppress the stripping of zinc by diaphragm, can make ion discharge plate 17 and reach long-life purpose from the back side of kirsite plate.The thickness of diaphragm is preferably more than 10 μ m.Thickness is during less than 10 μ m, and zinc ion has unnecessary stripping, so be undesirable.And about diaphragm, so long as can suppress the stripping of zinc ion, it is also unrestricted that it is formed.The diaphragm that for example can use known resin such as acrylic resin, urethane resin to form.
And, discharge the stripping of ion on the plate 17 in order to suppress ion, contact, guarantee its state of insulation with metalwork 18 and not short circuit is provided with the spin laced fabric that is about 1mm as the thickness of electric insulation layer.As long as it is hydrophilic that ion is discharged the electric insulation layer that is provided with on the plate 17, and can prevent that metal from getting final product with contacting of metal.For example can use the spin laced fabric of cotton or polyester, poly-urethane, nylon, polyvinyl alcohol etc.Spin laced fabric is because capillarity can fully keep moisture.Accumulate dew for a long time owing to adopt hydrophilic electric insulation layer that ion is discharged on the plate 17,, they are killed so can concentrate more bacterium, inhibition activity.And then, have under the situation of antibacterial action at the metal ion self of discharging plate 17 strippings from ion, because can the more metal ion of stripping, so can access the vegetative effect of higher inhibition.
