Description
Technical field
The utility model relates to a kind of exhaust fan, especially a kind of exhaust fan with magnetic switch.
Background technique
Traditional exhaust fan for being set to kitchen, exhaust fan are a kind of using extremely wide household electronic products, master
Wanting function is to exclude indoor oil smoke, the especially oil smoke in kitchen with outdoor air displacement, or pressure for indoor.Institute at present
The exhaust fan for producing and using is mostly covering and partition type axis stream exhaust fan for household, and the screening partition window leaf of this kind of exhaust fan is mostly shutter window
Leaf.This kind of exhaust fan is considered when designing: when energization, motor drives flabellum rotation by air pusher, opens blinds window cover.
Meanwhile indoor oil smoke is extracted outdoor, after motor power-off, flabellum stops operating, and back pressure disappears, and shutter due to repeating certainly
Position, is automatically closed indoor outer tunnel.However, from the point of view of present user is using middle the case where generally reflecting, by shutter
Oil smoke becomes tobacco tar after cooling, in addition impurity and dust that burning generates, gradually becomes greasy filth, paste is full cover in shutter and
In its shaft and mounting bracket, so that the opening and closing of shutter just less flexibly, cause to be powered within the not too long of time
Smoke extraction area greatly reduces.Since blinds apparatus is in the rearmost end of exhaust fan, cannot wipe, thus oil smoke is more and more thicker, very
To the blade that crushes, the function of movable louvre window lid is caused finally to lose.In addition, since the inner cone of pod is to indoor direction
It is widened, the cooling tobacco tar on rotation flabellum by centrifugal force effect, it is past along the conical surface after being thrown on the conical surface of pod
It flows down, although setting up oily bucket in the lower part of cover, effect is bad, still has many oil streams to the lower part of exhaust fan, often in box
There is oil, the outer drip of box is also oil.The deficiency as present in venetian blind type exhaust fan, and make people in further research row
When the development design of gas fan, it has to consider how to remove shutter, and use other cover board mode.
Traditional exhaust fan is contacted with power switch by direct hand and is opened, but in places such as kitchens, hand holds
Easy wet water, if directly contacting the danger for being easy to happen electric leakage with power switch.
The general exhaust fan for using clamshell, having part in the market is the exhaust fan using cover board, and cover board and exhaust fan are cut with scissors
Link, hinge socket part have touch switch, when cover board is opened, connect the touch switch, so that exhaust fan starts running,
But the structure is needed trace arrangements to hinge socket part, has certain difficulty to trace arrangements, while manufacturing not
It is convenient, it is also inconvenient to being replaced and cleaned for flip lid.
