Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] Such as figure 1 As shown, the jet generator for range hood provided by the present invention includes an outer casing 1 and an inner casing 2 arranged inside the outer casing 1, and the materials of the inner and outer casings can be made of plastics, iron sheets and other materials.

[0024] Both the outer shell 1 and the inner shell 2 are trumpet-shaped and the outer shell 1 is provided with an air inlet 3, the top edges of the inner and outer shells 1, 2 are connected to each other as one, and the bottom edge of the inner shell 2 is provided with an air inlet facing the outer shell. 1, the lower edge of the outer casing 1 is provided with a second hemming portion 5 facing the inner casing 2, and the gap between the second hemming portion 5 and the first hemming portion 4 forms a jet channel 6 . The angle α between the tangent direction at the opening of ...

Abstract

The invention discloses a fluidic generator applied on a smoke exhaust ventilator, comprising an outer shell and an inner shell arranged in the outer shell, wherein the inner shell and the outer shell are both in broadening formation, and the outer shell is provided with an air intake; the top edges of the inner shell and the outer shell are mutually connected into a whole; the bottom edge of the inner shell is provided with a first edgefold part towards the outer shell; and the lower edge of the outer shell is provided with a second edgefold part towards the inner shell, and a jet flow path is formed in a gap formed between the second edgefold part and the first edgefold part. The invention also discloses a jet flow type smoke exhaust ventilator adopting the fluidic generator. The invention is characterized in that the fluidic generator generates jet flow air flow, the air flow is mixed with soot gas to be discharged from a fume exhaust pipeline; vane wheels and the motor are completely separated from soot gas so as to solve the problem that vanes and fans are polluted by the soot gas, and realizing the purpose that the vanes and the fan are free from disassembling and washing for lives.

Description

technical field [0001] The invention relates to household kitchen equipment, in particular to a jet-flow range hood and a jet-flow generator thereof. Background technique [0002] The working principle of household range hoods commonly used at present is to directly place an axial-flow centrifugal fan on the exhaust passage to realize extracting oily fumes. Oil fume, cleaning after use is very troublesome, and even damage the centrifugal fan, greatly shortening the life of the machine. [0003] Chinese invention patents 98107575.4, 00134096.4, 01102828.9 and Chinese utility model patent 200620079304.2 respectively provide technical solutions for jet range hoods. The negative pressure generated by the jet gas is used to absorb oil fume, and the fan is completely isolated from the oil fume gas, thereby solving the above-mentioned common range hood. Existing defects, however, in the above-mentioned scheme, the injection ports of the jet gas produced by the jet range hood are a...
