Abstract

The bottom surface and bottom plate of wind box of cooking fume exhauster are made into the form of backward-inclined identical angle, and are respectively communicated with oil-dirt hole, dirt-leaking hole and oil-dripping hole by means of three-way discharge pipe, so that the dirt oil can be automatically discharged into oil-collecting cup. It has simple structure, reduces the cleaning difficulty caused by the deposition of oil dirt on the air box and the bottom plate, thereby reducing the cleaning times and facilitating the cleaning.

Description

A kind of waste oil collections tructure of smoke exhaust

A kind of waste oil collections tructure of smoke exhaust, it relates to the architecture advances of smoke exhaust.

Smoke exhaust to manufacture and design development in recent years very fast, structure is updated function and is gradually improved, but it is obvious inadequately to getting rid of sump oil minimizing alluvial degree, particularly bellows and smoke exhaust base plate generally all are designed to plane form, allow in its free blowdown person who lives in exile catchment cup,, promptly can remain in the bellows bottom surface very soon because greasy dirt is than thickness, just be set on the bottom surface after time is permanent, the sump oil that it not only influences is afterwards drained the cleaning difficulty that more can cause in the future.

The purpose of this utility model is the waste oil collections tructure that proposes a kind of smoke exhaust, and bellows and smoke exhaust base plate are all made the plane of being with gradient, reduces the alluvial of sump oil on base plate and bellows bottom surface, reduces pollution level and reduces wash number and clean difficulty.

The utility model is realized in the following way, all make by the α angle that preceding recedes identical and in they extreme lower positions with base plate the bottom surface of bellows, be shaped on smudged oil hole pipe and oil dripping hole, be enclosed within the smudged leakage hole tube outside of smudged oil hole pipe and draw-off tray respectively by the mouth of pipe of threeway blow-off pipe, the scope that another mouth of pipe stretches into the tilt angle alpha of bellows and base plate in the oil dripping hole of base plate is the 0-15 degree.

The advantage of the waste oil collections tructure of a kind of smoke exhaust of this utility model is, owing to bellows baseplane and smoke exhaust are all made the inclination equal angular make their reduce long-pending oil or contamination oil reduced the alluvial degree, thereby reduced the regular wash number of smoke exhaust and cleaned difficulty.

Accompanying drawing 2 is a kind of waste oil collections tructure cutaway view of smoke exhaust

In conjunction with the accompanying drawings the waste oil collections tructure of a kind of smoke exhaust of the utility model is described further below by embodiment: it is made up of shell, bellows, motor, fan, draw-off tray, base plate, catchment cup and threeway blow-off pipe.Wherein, shell 1, bellows 2, motor 3, fan 4, draw-off tray 5 is a conventionally form, the α angle that recedes is then made in the bottom surface of bellows 2, the α angle is that 0 ° to 15 ° present embodiment is chosen as 8, be equipped with smudged oil hole pipe 9 in its lowest position: its three mouths of pipe of threeway blow-off pipe 6 in one plane respectively are separated by 90 °, smoke exhaust base plate 2 is the shell 1 dustpan-shaped rectangular slab that is complementary down, two inlet scoops 12 are arranged above it, the angle that he tilts is identical with the bellows angle of inclination also to be 8, extreme lower position at it is shaped on oil dripping hole 13, periphery is shaped on the edge 11 that matches with shell 1 all around, their assembling is the bellows 2 of packing in the shell 1, motor 3, fan 4, draw-off tray 5, smoke exhaust base plate 7, edge 11 is stuck in below the shell 1, and its three mouths of pipe of threeway blow-off pipe 6 are set in the smudged oil hole pipe 9 of bellows lower end, adorn a catchment cup 8 formations outside the aperture of the smudged leakage hole pipe 10 of draw-off tray and in the hole of the oil dripping hole 13 on the base plate and in oil dripping hole 13 lower ends.

Claims (2)

1, a kind of waste oil collections tructure of smoke exhaust, it is characterized in that, all make by the α angle that preceding recedes identical with base plate (7) bottom surface of bellows (2), and be shaped on smudged oil hole pipe (9) and oil dripping hole (13) in extreme lower position, they are enclosed within smudged leakage hole pipe (10) outside of smudged oil hole pipe (9), draw-off tray (5) respectively by the mouth of pipe of threeway blow-off pipe (6), and another mouth of pipe is stretched the people in the oil dripping hole (13) of base plate (7).

2, by the waste oil collections tructure of the described a kind of smoke exhaust of claim 1, it is characterized in that the scope of the tilt angle alpha of bellows (2) and base plate (7) is 0-15 °.
