Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
As shown in Figure 1: a kind of simple and easy new blower fan, including casing 1, air exhaust passage 2, fresh air channel 3 and the heat exchanger 4 being located between air exhaust passage 2 and fresh air channel 3 in described casing 1, it are provided with；Described fresh air channel 3 includes new wind entrance 31 successively along inlet air flow path, for the low efficient filter 33 that outdoor air is filtered and electrostatic precipitator 34, for the high efficiency particulate air filter 35 that the new wind after sequentially passing through described low efficient filter 33, electrostatic precipitator 34 is filtered again, for being entered by the new wind after described high efficiency particulate air filter 35 to indoor fresh-air fan 32 and new wind outlet；Described air exhaust passage 2 includes air draft entrance successively along inlet air flow path, for indoor old wind is discharged to exhaust fan 21 and the wind exhausting outlet 24 of outdoor；Described air exhaust passage 2 is located at the lower section of high efficiency particulate air filter 35；Described electrostatic precipitator 34 is placed in the front side of heat exchanger 4.Air exhaust passage 2 is located at the lower section of high efficiency particulate air filter 35 by the present embodiment so that set structure is compacter, reduces package size.Electrostatic precipitator 34 is placed in the front side of heat exchanger 4, the dust entered in heat exchanger 4 can be reduced, improve the service life of heat exchanger 4.
As shown in Figure 2: in the present embodiment, the two ends of high efficiency particulate air filter 35 connect fixing by two inwalls that connector 36 is relative with casing 1 with bolt 361, and by connector, high efficiency particulate air filter 35 is spacing.Bolt 361 can be routine bolt, it is also possible to be wing nut.One end of connector 36 is fastened by bolt 361, the other end engaging high efficiency particulate air filter 35 of connector 36, loosens to avoid high efficiency particulate air filter 35 to produce.By loosering a bolt 361, high efficiency particulate air filter 35 can be taken off and be replaced, time saving and energy saving.It is appreciated that the attachment structure of high efficiency particulate air filter 35 can also is that other Demountable, such as clamping between the inwall of casing 1, hinged, riveted joint etc..High efficiency particulate air filter 35 is directly connected by the present embodiment with the inwall of casing 1, reduces machine packet size, reduces cost.
In the present embodiment, low efficient filter 33 adopts stainless steel cloth to make, and compared to existing cloth-bag type low efficient filter, stainless steel cloth can clean repeatedly, can improve filter effect, can reduce again cost.Described low efficient filter 33, electrostatic precipitator 34 are detachable connection, such as clamping, inlay, be spirally connected, rivet or hinged etc., to facilitate low efficient filter 33, electrostatic precipitator 34 change in time or clean.Low efficient filter 33, electrostatic precipitator 34, high efficiency particulate air filter 35 surrounding be all tightly connected, there is no filtered phenomenon to prevent from there is partial air.
PM10 can be filtered to about 70% by described low efficient filter 33, and can stop winged insect entrance.Electrostatic precipitator 34 by infinitesimal dust-filtering to 98%, can make high efficiency filter burden only have 2%；If not having electrostatic precipitator 34 between high efficiency filter, high efficiency particulate air filter 35 will soon block, and strainability is good also null(NUL) again, adds electrostatic precipitator 34 and not only can prevent high efficiency particulate air filter from blocking, also can killing pathogenic bacteria.On the basis of electrostatic precipitation, high efficiency particulate air filter 35 makes PM2.5 filter to more than 99.9%, is greatly improved New atmosphere quality.
The quantity of described fresh-air fan 32 is one, arranges a fresh-air fan 32 and can reduce the size of unit, reduces cost.Being appreciated that the quantity of fresh-air fan 32 can also for multiple, fresh-air fan 32 as shown in Figure 3 is two, it is symmetricly set on same level line, air output is increased, it is to avoid cause, due to the stop of high efficiency particulate air filter 35, the phenomenon that windage is big, significantly ensure that the smooth and easy of fresh-air fan 32 air-out.
Described heat exchanger 4 is heat-exchangers of the plate type, is shaped as the hexagon of rule relatively, it is preferred to regular hexagon, so can not be subject to the impact of putting position.Two inclined planes respectively new wind heat switching access and the exchange of new wind heat that regular hexagon is parallel export, and form fresh air channel 3；Regular hexagon parallel two other inclined plane respectively air exhaust heat exchange outlet and air exhaust heat switching access, formed air exhaust passage 2.When air draft and the new wind of entrance, the shape of heat exchanger 4 and structure can not only ensure the Uniform Flow of air draft, windage is little, air draft is smooth and easy, and when new wind enters in heat exchanger 4, forming the airflow convection heat exchange moved diagonally downward that the air-flow tilted upward to move is formed with air draft, utilization rate of waste heat is high, and energy-saving effect is much better than the heat exchanger of prior art.It is appreciated that heat exchanger 4 can also be other shape, such as irregular hexagon, as long as can guarantee that air exhaust heat exchange outlet communicates with between air exhaust heat switching access, communicates between new wind heat switching access and new wind heat exchange outlet.If heat exchanger is irregular hexagon, can be laterally disposed, it is possible to vertically place, it is preferred to laterally disposed, so enable to the structure in casing more compact, decrease package size.
Being appreciated that air draft entrance can be located at bottom and/or the sidewall of casing 1, the arrangement with air exhaust passage 2 is relevant.Air draft entrance is preferably located at the bottom of casing 1 by the present embodiment, old wind along inlet air flow path through over-heat-exchanger 4, particularly as follows: inlet air flow path is opened in the side-walls of casing 1, old wind enters the air exhaust heat switching access of heat exchanger 4 along the air exhaust passage 2 of sidewall.The air of air draft entrance can come from the contaminated high place of the air such as toilet, kitchen.Air exhaust passage 2 is located at side-walls, is located between heat exchanger 4 and fresh air channel 3 by air exhaust passage compared to existing, it is possible to the structure making casing 1 inner chamber is more compact, reduces the volume of complete machine.Described exhaust fan 21 is located at air exhaust heat exchange exit, and wind exhausting outlet 24 is located at the back side of casing 1, and air draft entrance connects with wind exhausting outlet 24.Described new wind entrance 31 is located at the back underside of casing 1, and the top of casing 1 is located in the outlet of new wind, and the outlet of new wind connects with new wind entrance 31.
It is provided with return air dividing plate 6 between described air exhaust passage 2 and fresh air channel 3, heat exchanger 4, is used for preventing from leaking out, stop to contact between old wind with new wind, it is to avoid reduce filter efficiency.
The inwall of described casing 1 is filled with acoustical cotton 11, has the advantage such as sound-absorbing, heat insulation, fire-retardant, high temperature resistant, light weight.
Described casing 1 is provided with safety switch 8, can cut off main power when the gate of unit is opened, play safety effect.
