Abstract

The utility model provides an air exchanger which absorbs in the outdoor fresh air and exhausts the air after filtering for the indoor using. At the same time, the indoor turbid air is exhausted out of the room so as to make the indoor air continuously flow, cycle and exchange and thus make the indoor air always fresh, comfortable and pollution-free. A casing which is provided with an air fan and an air outtake pipe is fixed on the air absorbing plate to form an air fan general. The air fan general is arranged in the machine case and is externally connected with a protective cover fixed on the machine case and a panel with an indication light; furthermore, the machine case is connected with a filter and an air outtake channel, and the air outtake pipe on the casing is connected in the air intake pipe of the machine case to form a dual-pipe that is communicated with the outside. Besides, the machine case is fixedly connected with a ventilation fan of the filter. As the air outtake pipe and the air intake pipe are concentric dual-pipes, the utility model has the advantages of compact structure and small occupation as well as better air purifying effect.

Description

Brethaid

Technical field

The utility model relates to a kind of air purifier, a kind of with the outdoor fresh air inspiration, discharge after filtering for indoor use, meanwhile indoor useless dirt, foul air are discharged into outdoorly, the brethaid that make that room air constantly flows, circulation, exchange is used, suitable especially just through the new home of finishing, quicken absorption, discharging, the processing of pernicious gas, and to using the room of air-conditioning, will circulate to exchange to its air and handle, it is fresh pure and fresh, pollution-free to remain room air.

Background technology

Along with improving constantly of people's living standard; people recognize; protect the environment and the space of oneself depending on for existence; improve the quality of life of controlling oneself, environmental requirement is placed on the agenda, the patent of relevant indoor air cleaner is arisen at the historic moment for this reason; though some is effective; but complexity as a result, the price height also is not suitable for general family and uses.

The patent No. 91227135.3 " air cleaner " provides a kind of branner that utilizes indoor self air to circulate, purify use, though it is simple in structure, cost is low, help keeping indoor environment temperature, but the time is with after long, because of no fresh air constantly replenishes, pure and fresh degree is poor, and result of use will be subjected to certain influence.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of brethaid is provided, and it is simple in structure, cost is low, and use, install, clean convenient, safety, and good purification, make room air pure and fresh, comfortable.

The utility model solves above-mentioned technology: brethaid is fixed on by the housing that blower fan is installed and has a discharge pipe and constitutes the blower fan assembly on the air draught plate, be installed in the cabinet, the panel that it is externally connected with the protective cover that is fixed on the cabinet and has indicator lamp, also be connected with filter on the cabinet and the exhaust passage constitutes, and the discharge pipe on the described housing is connected in the blast pipe of cabinet, constitute and outdoor communicate two-tube also fixedly connected ventilation fan in the described cabinet facing to filter.

Compared with prior art: advantage of the present utility model is: so the fresh air that will come in by blast pipe of interchanger, indoor through delivering to after the filter filtration, and after the inspiration of blower fan assembly, be discharged into indoor foul air outdoor from discharge pipe, because of there being external air constantly to replenish, quickened circulation, exchange, the convection current of room air, thus make room air more pure and fresh, feel more comfortable, pollution-free.

In addition, because of discharge pipe and blast pipe are concentric double pipe, its compact conformation, the shared confined space are little, and select for use installation in different directions blower fan and ventilation fan each play not same-action, make the exchange effect better.And the lower end of blower fan assembly also has a discharge pipe, the air sent is dammed through deep bead reclaim 10%, again after its terminal return air filter that connects filters, flows to indoorly, helps keeping indoor environment temperature.

The specific embodiment

Below in conjunction with the embodiment accompanying drawing the utility model is described in further detail:

In the middle of the cabinet (1) lateral partitions (7) is arranged, be divided into upper and lower two chambeies, the bottom surface is that the louver board of cover plate (21) in addition is exhaust passage (8), and respectively there is a joint hinge (19) rear surface for four jiaos, and a blast pipe (3) is arranged in the middle of the sidewall.

Protective cover (14) is the shutter cover plate, and outdoor protective cover (2) is the middle rectangular box that through hole is arranged, and cover cap (5) is a louver board.

Air draught plate (16) has the thin plate of bringing the air port into that cooperates with blower fan (18) interstitial hole for the centre.

Filter (9) is a drawer type, by nonwoven (10) doubling, build up 4 layers of filter course, is clamped on the bottom of drawer.

Filter (12) is fixed on the middle formation of deckle board by the filter course that nonwoven is folded into.

Housing (17) is a scroll casing type, its lower end and a side respectively have a discharge pipe (13), (4), and by lower end discharge pipe (13) air inlet, are fixed with a return air plate (15), in the air outlet place slide rail, go back drawer type and connect and the identical filter (12) of filter (9) effect.

Blower fan (18) is a centrifugal fan, is installed in the housing (17), is screwed at air draught plate (16) and goes up formation blower fan assembly.

Extension pipe (22) is middle two concentric tubes that gripper shoe is arranged.

The blower fan assembly is screwed in the epicoele of cabinet (1), the discharge pipe of one side (4) passes blast pipe concentric on the sidewall (3) hole, stretch out outside the cabinet (1), extend in cabinet (1) cavity of resorption and lower end discharge pipe (13) passes dividing plate (7), ventilation fan (6) is screwed on the lower surface of dividing plate (7).

The panel (1) that has indicator lamp (20), be screwed on cabinet (1) outer surface that ventilation fan (6) is located, again filter (9) is installed in following cabinet (1) chamber of ventilation fan (6), outdoor protective cover (3) is fixed on the end face and cabinet (1) of blast pipe (3), cover cap (5) is fixed on the end face of discharge pipe (4), and brethaid is assembled into.

This interchanger is hung on the indoor overhead wall more than 1.6 meters, and by-pass cock is installed on the wall of lower position, is convenient to operation, and discharge pipe (4), blast pipe (3) extend to outdoor, because of the difference of installation site, available extension pipe (22) spreading is regulated.

During use, opening power, blower fan (18) sucks the chamber in the fan blade assembly with muddy air, discharge outdoor through housing (17) and discharge pipe (4), meanwhile outdoor air enters cabinet (1) from blast pipe (3), enters filter (9) through ventilation fan (6), after treatment in the inlet chamber of exhaust passage (8), so constantly convection current, circulation, exchange, the purpose of reach air cleaning, improving the quality of living.

Because of indoor and outdoor temperature has difference, especially in winter, the inhaled air temperature is very low, and indoor warmer is arranged, and it is bigger that temperature differs, and indoor temperature can be reduced.Thereby a discharge pipe (13) has also been designed in the interchanger lower end, the hot-air of discharging can be dammed through return air plate (15) and reclaim about 10%, and through after filter plate (12) processing, entering filter (9) handles in the inlet chamber once more, promptly made full use of the recovery energy, and it is too many that indoor air temperature is reduced, and influences people's life.

Time can be pulled down the nonwoven (10) in the filter (9) with after long, with the impurity of absorption on it, filtration, after the thorough cleaning treatment of water, reuses again.
