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 250 watts, it still cannot prevent the fan from being polluted by oil and effectively solve the problem of difficult cleaning.

Embodiment Construction

[0015] The annular jet nozzle (nozzle) of the present invention is composed of an annular interlayer between the annular outer body at the mouth of the oil fume pipe 3 and the annular inner body of the jet sleeve 4. As long as the electric fan 1 is turned on, air suction can be generated. The jet flow is drawn from the 3 channels of the oil fume suction pipe in the center. In the structure of the present invention, the gas source input pipe 2 and the oil fume connecting pipe 6 are both very short.

[0016] The air-inducing jet ejected from the outer annular nozzle, after leaving the annular nozzle, spreads in a centripetal compression type (the loss of injection force is small), and forms a low pressure, which is entrained by the smoke in the oil fume pipe 3 from its central position. Oil fume, the strength of its roll to absorb oil fume is stronger. In addition, although the double-walled surface in the above-mentioned interlayer has a relatively large flow resistance to the...

Abstract

The invention consists of a cooking fume removing hood made of plastics, a centrifugal fan and a jet entrainment member made of plastics consisting of a jet sleeve and a cooking fume removing tube inside. There is an outer ring jet nozzle in the outer ring sandwich of the jet sleeve and the cooking fume removing tube, and the air jet-flow is jetted from the said sandwich. The said jet sleeve and the centrifugal fan are located outside the room.

Description

Technical field: [0001] The present invention relates to the technology of kitchen range hood. Background technique: [0002] At present, from the structural point of view, the traditional models are all designed by the method of directly sucking the oil fume by the electric fan in the oil fume suction and discharge channel. The disadvantages are: cleaning is difficult, especially the problem of difficult cleaning caused by oil pollution of the electric fan, and the problems caused by the oil pollution of the electric fan. The associated problems caused by this (the fan blades are out of balance after sticking to the oil, the noise is increased and the air suction volume is reduced) are the most annoying and need to be solved. The latest model design at home and abroad is to add a fume filter: small mesh, good filtering efficiency, and small airflow; while large mesh, poor filter efficiency, and large airflow. It is difficult to unify the mesh and airflow. Although the fan ...
