Abstract

The utility model relates to an automotive air purifying device. The front part of an air conditioning evaporator for an automobile is provided with an air filtering partition board which forms a plurality of accommodating chambers in which a plurality of filtering materials are filled. The indoor and the outdoor air of the automobile is filtered by the filtering materials, and then the air-conditioning evaporator conducts the heat exchange for the air so as to generate purified air.

Description

Automotive air purifying device

The utility model relates to a kind of Vehicular air clean-up device, and particularly relating to a kind of turnover a/c system evaporator that filters provides the air purification unit that purifies air and use for air-conditioning.

The a/c system of general automobile is provided with an evaporator (being commonly called as cold type), oneself in the a/c system in car is circulated, also can be from the extraneous air that imports, see also Fig. 1, evaporator 1 has a plurality of evaporating tubes 11 and fin 12, when inner air outflow or air outside inflow evaporator 1, because of the refrigerant (not shown) heat absorption of the evaporating tube 11 of evaporator 1 is evaporated, in this endothermic process, air via evaporator 1 is passed to evaporating tube 11 and fin 12 with heat, for refrigerant heat absorption evaporation, make air obtain cooling, and aqueous vapor contained in the air is also because of cooling is condensed on the evaporator 11, so can be cooled and dehumidify by the air of evaporator 11, the passenger used in the air of formation cool drying was bought car in installments.

If someone is smoking in car, though cigarette can pass through evaporator 1 and the condenser (not shown) is discharged outside the car, but still can second-hand-cigarette be flow back in the car again because of evaporator 1 and the continuous ringing of condenser, cause in the car full of smoke.And if the outside air poor quality, regular meeting makes in the car passenger be drawn onto to contain a large amount of impurity and the unpleasant air of stench.

Main purpose of the present utility model provides a kind of air purification unit that filters turnover a/c system evaporator, uses for a/c system to provide to purify air.

Feature of the present utility model is that a filter air bound plate is installed in A/C evaporator the place ahead of vehicle, filters the air of leading through A/C evaporator by filter air bound plate, purifies air for using with generation.

For this reason, a kind of Vehicular air clean-up device of the present utility model, mainly comprise an A/C evaporator and a filter air bound plate that has a plurality of evaporating tubes and be consolidated in fin on the evaporating tube, A/C evaporator is installed in the a/c system place in the car body, A/C evaporator the place ahead is arranged with and forms an inside casing, sets filter air bound plate in the inside casing, and filter air bound plate is provided with a plurality of regular hexagon accommodating chambers, fill the filter material as active carbon granule in the accommodating chamber, each is with an adhesive-bonded fabric sealing for forward and backward of filter air bound plate.

When air recirculation car outer air enters A/C evaporator in the car, elder generation is the adhesive-bonded fabric of air bound plate after filtration, adhesive-bonded fabric can intercept oarse-grained impurity in the air, again via other impurity of activated carbon absorbing and filtering and the airborne peculiar smell of accommodating chamber, then, pass another side adhesive-bonded fabric 24, flow out A/C evaporator at last.Import in the car through cleaned air passes, can provide peace and quiet air to passenger in the car, and, few via filtered air impurity, also improved air cooled efficient.

Below by most preferred embodiment and accompanying drawing Vehicular air clean-up device of the present utility model is elaborated, in the accompanying drawing:

Fig. 1 is the plan sketch of a/c system evaporator in the past.

Fig. 2 is the exploded perspective view of the utility model preferred embodiment.

Fig. 3 is the assembled sectional view of the utility model preferred embodiment.

See also Fig. 2, Vehicular air clean-up device of the present utility model mainly comprises an A/C evaporator 10 and a filter air bound plate 20.

Being installed in the A/C evaporator 10 at a/c system place in the car body has a plurality of evaporating tubes 11 and is consolidated in a plurality of fins 12 on the evaporating tube 11, A/C evaporator 10 the place aheads are arranged with a rectangle inside casing 13 that forms appropriate depth, and inside casing 13 top peripheries are provided with most lockholes 14.

In the inside casing 13 of A/C evaporator 10, set a filter air bound plate 20 that utilizes plastic-steel to make the rectangle framework, filter air bound plate 20 just can embed in the inside casing 13, filter air bound plate 20 peripheries are provided with the lock ear 21 of similar number with respect to lockhole 14 places, and be example with the screw with lock-connecting piece 30(present embodiment) the locking location, form most orthohexagonal accommodating chambers 22 on the filter air bound plate 20, filling most filter material 23(present embodiments in the accommodating chamber 22 is example with the active carbon granule), before filter air bound plate 20 outsides, it is example with the adhesive-bonded fabric that ventilative cloth 24(present embodiment of sealing is distinctly pasted in the back).

See also Fig. 3, when assembling the utility model, will filter air bound plate 20 earlier and embed in the inside casing 13 of A/C evaporator 10, again with lock-connecting piece 30 lockings, after use a period of time, the filter air bound plate 20 that detachably changes the outfit new, quite easy in assembly and dismounting.

Please continue to consult Fig. 3, during use, when air recirculation in the car or car outer air are desired to enter A/C evaporator 10, must be earlier air bound plate 20 after filtration, at this moment, air passes adhesive-bonded fabric 24 earlier, adhesive-bonded fabric 24 can intercept oarse-grained impurity in the air, again via other impurity of activated carbon 23 absorbing and filterings and the airborne peculiar smell of accommodating chamber 22, then, pass another side adhesive-bonded fabric 24, flow out A/C evaporator 10 at last.Import in the car through cleaned air passes, can provide peace and quiet air to passenger in the car, and, few via filtered air impurity, also improved air cooled efficient.

The utility model is the filter material main body with active carbon granule 23, be because active carbon granule 23 surfaces have numerous pore, improve area of contact with air, so the effect of filtration, purification is good, the utility model will be filtered air bound plate 20 and place A/C evaporator 10 the place aheads, be because if filter air bound plate 20 places A/C evaporator 10 rears, the water droplet that air is condensed into via A/C evaporator 10, during air bound plate 20, can be stained with the surface that overlays on active carbon granule 23 after filtration, and lower the effect that active carbon granule 23 purifies air, so, filter air bound plate 20 must be placed in the place ahead of evaporator 10, in addition, hexagon accommodating chamber 22 fills for active carbon granule 23, can improve the capacity of unit area, increase the filtering effect, and adhesive-bonded fabric 24 also has the function that intercepts impurity except active carbon granule 23 being locked in the filter air bound plate 20.In sum, device of the present utility model is quite simple, purifies air but but can reach, and the effect of impurity screening peculiar smell is used with passenger in buying car in installments, and impurity screening, also can increase air cooling (or heating) effect.
