Problems solved by technology
[0002] At present, from the structural point of view, the traditional models are all designed by using the method of direct oil fume absorption by the electric fan in the oil fume suction and exhaust channel. The associated problems caused by this (unbalanced fan blades with oil sticking, increased noise and reduced air suction volume) are the most annoying and need to be solved.
It is difficult to unify the mesh and air flow. Although the fan power of some foreign models of range hoods has been increased to more than 200 watts, it still cannot prevent the fan from being polluted by oil and effectively solve the problem of difficult cleaning.
[0003] Patent ZL200520101717.1 discloses a complete machine structure of an outer ring jet type range hood. Its shortcoming is that its outer ring air jet entrainment sleeve protrudes out of the wall and is perpendicular to the outer wall. The distance is too long , the adaptability of its structure and shape is not strong

Embodiment Construction
[0014] The outer ring jet nozzle is formed by the interlayer between the annular outer body of the oil suction pipe 3 and the annular inner body of the jet sleeve 4 . The air jet generated by the fan 1 is ejected from the above-mentioned outer ring jet nozzle through the flexible air jet output pipe 2, and the entrained oil fume passes through the oil suction hood 7, the flexible connecting pipe 6, and finally passes through the oil suction pipe 3 on the wall 5 The outer horizontal rotation angle is about 90 degrees and is sucked out in the jet entrainment sleeve 4 again, and is discharged out in a direction substantially parallel to the outer wall 5 together with the air jet. ——The jet entrainment sleeve 4 is located on the upper edge of the window, and its outlet direction can be slightly inclined downward (for example: 3 degrees), which is convenient for outdoor oil collection.
[0015] The air jet flow ejected from this outer annular nozzle has a stronger power to entrain ...

This invention relates to an abnormal outer circle fluidic absorbing and exhausting set composed of a lampblack cover, a centrifugal fan and an inject entrainment device including an fluidic entrainment sleeve and an oil absorption tube in it, in which, the air blown out from the centrifugal fan is sprayed from the spraying tube composed of the outer circle interlayer of the inject entrainment sleeve and the absorption tube, the part extending out of the door of the tube is in a 90deg. corner, so that the sleeve is parallel to the wall basically, the tolerance sphere of said 90deg. is from 90 to 110 deg. the centrifugal fan can be set outdoor that will not influence indoor.
Description
Technical field: [0001] The invention relates to kitchen range hood technology. Background technique: [0002] At present, from the structural point of view, the traditional models are all designed by using the method of direct oil fume suction by the electric fan in the oil fume suction and exhaust channel. The associated problems caused by this (unbalanced fan blades with oil sticking and increased noise and reduced air suction volume) are the most annoying and need to be solved. The current latest model design at home and abroad is to add oil fume filter screen: small mesh, good filtration efficiency, and small air flow; while large mesh, poor filtration efficiency, large air flow. It is difficult to unify the mesh and air flow. Although the fan power of some models of range hoods abroad has increased to more than 200 watts, it still cannot prevent the fan from being polluted by oil and effectively solve the problem of difficult cleaning.
