Abstract
The present invention provides a novel scavenger fan which is characterized in that an air inlet channel and an air discharge channel leading to the inside and the outside of a room are respectively arranged in the novel scavenger fan of the present invention. A movable air door is also respectively arranged in each of the air channels. The novel scavenger fan can realize indoor and outdoor bidirectional air exchange, circularly purify indoor air and make indoor and outdoor air carry out air heat exchange in the scavenger fan by regulating the positions of the movable air doors. When temperature difference between indoor and outdoor air is too large, the temperature of outdoor air can be made to approach or reach the temperature of indoor air by the air heat exchange of the scavenger fan, and then the outdoor air is discharged into the room. An air filter and purification device is also arranged in the scavenger fan to effectively block outdoor mosquitoes, insects, dust, etc., and fresh air is discharged into the room after purified by the air filter and purification device.
Description
The present invention relates to a kind of ventilation fan, particularly a kind of air scavenger fan.
The ventilation fan that present people generally use has 2 kinds of situations, a kind of is axial fan type, the big blast of this kind ventilation fan volume simple in structure is very little, occurs the phenomenon of downdraught when being everlasting outdoor blowing, 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 structure that adopts centrifugal fan type, this kind ventilation fan volume is little, blast is very high, but therefore 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 when outdoor temperature is lower than indoor temperature, people dare not arrange outdoor refrigerant air into indoor, because above-mentioned ventilation fan can't blocks dust and mosquito because of the restriction of its structure, when to indoor exhaust, also arrange dust and mosquito into indoor.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 bulletin CN2105636U that overcomes the above problems provides " air cleaner " its principle is on the suction port in fan air channel air filter to be housed, to the air stream that passes through produce filter absorption do with and utilize, indoor self air carries 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 that a kind of volume is little, function is many, have two-way ventilation, 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, and are respectively equipped with airintake wind-tunnel and exhaust duct that indoor and outdoors communicates in casing of the present invention, and by the movable air door that is located in the air channel, the wind direction of control air channel apoplexy.Movable air door also is provided with the neutral position in airintake wind-tunnel so that make the air of indoor and outdoors be inhaled into and be mixed into the heat exchange of line space gas simultaneously so that make outdoor air near or reach the temperature of indoor air after, advance indoor row.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 filter that can take out cleaning is housed also, so that can effectively filter air, simultaneously can stop that also outdoor mosquito and dust make it can not arrange into indoor, pure and fresh air is being arranged into indoor then, just reached purpose of the present invention according to the above.
The present invention has been owing to adopted above-mentioned principle and structure, so the present invention compares with common ventilation fan, has the ventilation of air-filtering ventilation and air heat exchange, indoor air filtration circuit function, will arrange into indoor near room temperature and pure and fresh air then.
Is to do further detailed description below with reference to drawings and Examples to this.
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 will produce when the air grid (12) that dispels the heat will be machine (4) work 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 in the airintake wind-tunnel (6) and has been led to indoor air passage portion, 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 from indoor suction port (8) and outdoor suction port (9) respectively, and enter and be mixed into the heat exchange of line space gas in the centrifugal cutter air channel (3), by centrifugal cutter (2) heat-exchanged air is arranged in the intake and exhaust air channels (7) then, in exhaust duct (7), also be provided with movable air door (4) and air door positioning work piece (15) and logical adjusting hand lever (16) and movable air door (14) be transferred to the position of setting, when movable air door (14) is transferred to the position of exhaust duct one's intention as revealed in what one says door shelves (18), 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 arranged into indoor from the movable air grid (10) that is located on the indoor exhaust mouth, when movable air door (14) is transferred to the position of exhaust duct one's intention as revealed in what one says door shelves (17), 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 the air grid (11) that is contained on the outdoor exhaust outlet air is arranged to outdoor, on outdoor mouthful (9) and indoor mouthful (8) of airintake wind-tunnel (6), air filter (13) is housed respectively also, in order to stop mosquito and dust and into indoor with arranging at pure and fresh air after the air-filtering.
