Abstract
The invention provides a kind of novel ventilation fan, be characterized in air scavenger fan of the present invention, be provided with the airintake wind-tunnel and the exhaust duct that lead to indoor and outdoors respectively, and movable air door is housed also in the air channel, by can accomplish the two-way ventilation of indoor and outdoor to this air scavenger fan of adjustment of movable damper positions, carry out circularly purifying with indoor air, and allow the air of indoor and outdoor in this ventilation fan, carry out air heat exchange, with the difference in air temperature of convenient indoor and outdoor when too big, air heat exchange by this machine, can make outdoor air temperature near or the temperature that reaches indoor air advance indoor row then, air-filtering and purification plant also are housed in this machine, can effectively stop outdoor mosquito dust etc. and indoor again pure and fresh air being entered after the air purification.
Description
The present invention relates to a kind of ventilation fan, particularly a kind of novel ventilation fan.
The ventilation fan that present people generally use has 2 kinds of situations, a kind of is axial fan type, the big very little phenomenon that downdraught when being everlasting outdoor blowing, occurs of blast of this kind ventilation fan volume simple in structure, so people often are contained in this kind ventilation fan and do air draft in the environment such as kitchen, dining room and use.And the another kind of little blast of this kind of structure ventilation fan volume of centrifugal fan type that adopts is very high.Therefore but function singleness often is installed in the building of building structure complexity and uses in the toilet.Also having the people above-mentioned ventilation fan to be contained in the environment such as parlor, room uses, but but make troubles to people, as summer people when outdoor temperature is lower than indoor temperature dare not enter outdoor refrigerant air indoor, because above-mentioned ventilation fan can't blocks dust and mosquito because of the restriction of its structure, also enter dust and mosquito indoor when in indoor row.Therefore people dare not be installed in this ventilation fan graceful room easily, use in the environment such as parlor.
For the not enough Chinese patent notification number CN2105636U3 that overcomes the above problems provides " air cleaner " its principle is that the air-filtering layer is housed on the suction port in fan air channel, to the air stream that passes through produce filter absorption do with and utilize indoor self air to carry out circularly purifying and with outdoor irrelevant.Therefore above-mentioned device can only make indoor air circulate and purify indoor, and outdoor pure and fresh air can not be entered indoorly, and air that can not indoor a large amount of dirts is discharged, and therefore makes troubles equally to the user.
At above the deficiencies in the prior art, the objective of the invention is to provide the little function of a kind of volume to have two-way ventilation more, the indoor air circulation also has multifunctional novel ventilation fans such as air-filtering, air heat exchange.
The present invention such as following mode are finished, in casing of the present invention, be respectively equipped with the airintake wind-tunnel and the exhaust duct that communicate with indoor and outdoors, and by the wind direction that is located at the movable air door control air channel apoplexy in the air channel, movable air door is also established the neutral position so that make the air of indoor and outdoors be inhaled into and be mixed into the heat exchange of line space gas simultaneously in airintake wind-tunnel, so as to make outdoor air near or the temperature that reaches indoor air enter indoor.Conversion by movable air door can also be carried out indoor air circulation.On indoor mouthful and outdoor mouthful of airintake wind-tunnel, the air filtration and purification apparatus that can take out cleaning is housed also, can stop also simultaneously that outdoor mosquito and dust make it can not arrange and into indoorly pure and fresh air is being entered indoor then so that can be effectively air be filtered, just reach purpose of the present invention according to the above.
Below with reference to drawings and Examples the present invention is done further detailed description.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of positioning work piece among the present invention.
With reference to Fig. 1 motor (4) motor being housed in casing (1) is fixed in the casing (1) by electric machine support (5), being provided with the heat that produces when heat radiation air grid (12) is worked motor (4) in the back of motor is dispersed into outdoor, centrifugal cutter (2) is housed on motor (1) and is provided with centrifugal cutter air channel (3), after centrifugal cutter is by driven by motor work, in centrifugal cutter air channel (3), produced wind-force, at this moment air is inhaled into from airintake wind-tunnel (6), in airintake wind-tunnel (6), be provided with movable air door (19), the position that the position of movable air door selects movable air door (19) to be set by the air door positioning work piece (20) that is contained on the airintake wind-tunnel by adjusting hand lever (21), when movable air door (19) is transferred to the position of wind passage mouth air door shelves (22), movable air door this moment (19) has been closed and has been led to indoor air channel in the airintake wind-tunnel (16) partly, this moment, air was inhaled into airintake wind-tunnel from outdoor suction port (9), when movable air door is transferred to the position of wind passage mouth air door shelves (24), at this moment air is inhaled into the air channel in the suction port (8) of indoor end, and when movable air door (19) is transferred to the position of wind passage mouth air door shelves (23), at this moment air is inhaled into airintake wind-tunnel (6) simultaneously and enters from the outdoor suction port (9) of indoor suction port (8) respectively and is mixed into the heat exchange of line space gas in the centrifugal cutter air channel (3), by centrifugal cutter (2) heat-exchanged air is entered in the exhaust duct (7) then, in exhaust duct (7), also be provided with movable air door (4) and air door positioning work piece (15) and movable air door (14) be transferred to the position of setting by regulating hand lever (16), when movable air door (14) is arrived the position of exhaust duct one's intention as revealed in what one says door shelves (18) by height, movable air door this moment (14) has been closed exhaust duct and has been led to outdoor part, at this moment air can only be discharged into from exhaust duct and lead to the indoor air channel, and air is entered indoor from the movable air grid (10) that is located on the indoor exhaust mouth, when movable air door (14) is arrived the position of exhaust duct mouth register shelves (17) by height, air door has been closed exhaust duct and has been led to indoor part, at this moment air is arranged again in leading to outdoor exhaust duct, by be contained in air grid (11) on the outdoor exhaust outlet air is discharged to outdoor, on outdoor mouthful (9) and indoor mouthful (8) of airintake wind-tunnel (6), also be equipped with respectively air filtration and purification apparatus (13) in order to stop mosquito and dust and with air-filtering purify afterwards pure and fresh air is arranged into indoor.
On air door positioning work piece (20), be provided with positioning hole (25) and air door adjustable lever (21) be fixed on the position of setting with reference to Fig. 2, positioning shaft (27) is housed on the position that air door positioning work piece and adjustable lever (21) join movable air door (19) is housed and decides device (20) by adjusting hand lever (21) and air door movable air door (19) is transferred on the position of setting at the other end of adjustable lever by positioning bead (26).Just reached purpose of the present invention according to the above.
