Abstract

An air clarifier for air conditioner is composed of heater, heating controller and catalyzer, and features that said heater is a finned square body with metal frame around the fin and is attached to front of evaporator in air conditioner, and said catalyzer comprises the absorbent consisting of SiO2, or aluminium oxide, or their mixture and the active component composed of La, or Ce, or their mixture and Rh, or Pd, or Pt, or Ru, or Ir, or their mixture. It serves to both absorb harmful gas in air and oxidize and decompose it to make air fresh.

Description

Air conditioner air purification device and catalytic body thereof

The present invention relates to air cleaning unit, particularly a kind of air cleaning unit and the catalytic body thereof that effectively to remove pernicious gas in the air in the air-conditioner that be arranged on.

In the air-conditioning field of employment, because all kinds of article of smoking and place placement all can cause air pollution to surrounding environment artificially, and continuous circulation is gathered in this closed space, cause containing pernicious gas in the air in the air-conditioning field of employment, the harm people's is healthy.By a large amount of data-searching, the domestic and international market does not have this series products that can remove pernicious gas to appear on the market at present.

The objective of the invention is to provide a kind of and can thoroughly remove and absorb airborne pernicious gas, simultaneously air conditioner air purification device that again can fresh air at the problems referred to above.

Technical solution of the present invention is; Purifier is made of heater, heating control circuit and catalytic body, and heater is the square body with wavy fin, the flow front end of evaporimeter in the passage of the circulating air that is arranged on return air inlet in the air-conditioner after having the fin fixed frame fixing around the fin.Said catalytic body is arranged on fin and the fin fixed frame, adds middle part and the fin fixed frame that Thermal Control Element is arranged on heater and connects together.

Catalytic body of the present invention is by silica (SiO ₂) or aluminium oxide (Al ₂O ₃) or the absorbent that constitutes of above the two mixture; The active ingredient of being made by the 8th family (VIII) elemental rhodium (Rn) in rare-earth elements of lanthanum (La) or cerium (Ce) or its mixture and the periodic table or palladium (Pd) or platinum (Pt) or nail (Ru) or iridium (Ir) or its mixture constitutes jointly.By the catalytic body that above-mentioned two parts constitute, can adsorb effectively and the airborne pernicious gas of oxidation Decomposition.

Do not have metal frame around the said heater fin of the present invention and fix, fin directly is fixed on the heating element heater surface, and catalytic body forms on fin.

Heater element of the present invention is made by PTC heating material or heating wire.

The invention has the advantages that: after effective catalytic body oxidation processes, can thoroughly remove and absorb the pernicious gas of closed space inner accumulated, utilize the mobile passage of return air inlet circulating air in the air-conditioner simultaneously, send into the interior space by air outlet after making the purified treatment of pernicious gas that circulates in the air, reach the purpose of air cleaning by the band catalytic body.Have advantages such as simple in structure, reasonable in design, enforcement convenience.

Below in conjunction with accompanying drawing the present invention is illustrated

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the partial enlarged drawing of Fig. 1;

Fig. 3 is another enforcement illustration of Fig. 1;

Fig. 4 is principle of electric-heating figure of the present invention;

Fig. 5, Fig. 6 are two kinds of different user mode reference diagrams;

Fig. 7 is another enforcement illustration of Fig. 1.

As shown in Figure 1 and Figure 2, this heater is the square body with wavy fin 8, and it is made of stratiform catalytic body 6, metal fixed frame 7, fin 8, heating control circuit.The flow front end of evaporimeter 3 in the passage of the circulating air that is arranged on return air inlet in the air-conditioner after having fin metal frame 7 fixing around the fin 8.Catalytic body 6 is arranged on the outer surface (as shown in Figure 2) of fin and fin fixed frame, and the heater element PTC of heater is arranged on this calandria middle part, connects together with the fin fixed frame.Because heater has fin, the contact-making surface of heater and air is increased, that is be that the catalyst of additional heat device and fin surface contacts increase with the gas that flavor is arranged, thereby raising is adsorbed and the ability of oxidation Decomposition greatly.

As shown in Figure 3, this heater is finned tetragonal body, does not establish metal frame all around and fixes, and fin directly is fixed on the surface of heating element heater 9, divides two-layer formation up and down, and its stratiform catalytic body 6 forms at fin surface.

As shown in Figure 7, this heater is finned tetragonal body, establishing metal frame all around fixes, fin directly is fixed on the surface of heating element heater 9, forms in its graininess catalytic body 6 space between fin and fin, is sealed by wire netting 10 before and after the fin, prevent that the graininess catalyst runs off, because the appendix amount of catalyst increases, catalyst and the increase that contacts that flavor gas is arranged further improve absorption and oxidative decomposition capacity.

As shown in Figure 4, be the control and the safety protective circuit of this device, the wiring I of heater is connected in the circuit; J is a bimetal release, and this switch is in the normal open duty at low temperatures, reach uniform temperature after; auto-cutout treats to recover again when temperature drops to rated value normal open state.K is a metal fuse, and work keeps normal open under the fusing-off temperature point as long as be in.After temperature surpasses striking point, will open circuit, play the circuit protection effect.H is a heater element 9, and it can be the PTC exothermic material, also can be that heating wire (resistance wire) is made.

Catalytic body 6 of the present invention is by silica (SiO ₂) or aluminium oxide (Al ₂O ₃) or the absorbent that constitutes of above the two mixture, the pernicious gas composition in the absorbed air effectively; The active ingredient of being made by the 8th family (VIII) elemental rhodium (Rn) in rare-earth elements of lanthanum (La) or cerium (Ce) or their mixture and the periodic table or palladium (Pd) or platinum (Pt) or ruthenium (Ru) or iridium (Ir) or their mixture can promote airborne pernicious gas oxidation to separate when heating effectively in addition.Catalyst is cut out on the surface of the radiating fin 8 and the fin fixed frame 7 of heater by coating after the sinter molding or dress, and the fin of the placement of fin and air-conditioner evaporator 3 is arranged balance.This catalytic body is a vesicular texture, can adsorb the pernicious gas composition of being with peculiar smell effectively.

As Fig. 5, shown in Figure 6: 1 is the air intake vent airstrainer, and room air enters into air conditioner through the airborne suspension of screen pack elimination.2 is air cleaning unit, and the heater of this device is that Kai Heguan is controlled, can close automatically after energising a period of time, above-mentioned repeatedly then start-stop action.3 is the evaporimeter in the air-conditioner, is arranged on the rear side of air cleaning unit, enters evaporator cools through cleaned air passes.4 is the Air Blast fan of air circulation, sends into the interior space through air outlet 5 under the driving of the fresh air after the evaporative cooling at fan.
