Description
Technical field
The utility model is related to a kind of machine for kitchen use, especially a kind of range hood.
Background technology
Traditional range hood is considered as the suction of point sink formula, the energy attenuation of inspiratory airflow quickly, with leaving meeting point
The increase of distance, flow velocity is decayed in quadratic power, causes the smoking areas very little of the actual control of range hood.Current some fume-exhaustings
Machine realizes preferable smoke absorption effect by improving air quantity, causes to aspirate substantial amounts of air to discharge little oil smoke,
Namely the actual fume-exhausting of lampblack absorber is inefficient.
In order to solve above-mentioned deficiency, propose to form air curtain so as to the range hood for preventing oil smoke excessive, such as application number
A kind of concealed-type wind-curtain range hood disclosed in 201110327839.2 Chinese patent application, including outer cover, exhaust fume collecting hood and master
Cabinet, sets air curtain module between outer cover and exhaust fume collecting hood, air curtain module includes blower fan and air channel portion, the air outlet of blower fan and air channel
Portion is connected, and air channel portion includes air duct cover board and air channel base plate, and the air channel of flat is formed between air duct cover board and air channel base plate.
However, this range hood, because air curtain module is positioned only at front side, formation is single air-out air-flow, thus causes easily to exist
Both sides formation oil smoke is excessive, and smoke absorption effect is still waited to improve.
Additionally, also have proposing a kind of range hood for forming artificial spout, such as Application No. of the applicant
A kind of range hood for forming artificial spout disclosed in 201410176912.4 Chinese patent, including air intake blower fan, give
Wind blower fan and cyclone, are provided with the longitudinal air intake passage and the ring being trapped among outside longitudinally through passage positioned at middle part on cyclone
Shape air-supply passage, longitudinal air intake passage is connected with the air inlet of air intake blower fan by blast pipe, the upper end of annular air supply channel
It is connected by discharge pipe with the air outlet of breeze fan, the bottom of annular air supply channel forms the gas blowed out for breeze fan
Flow the gas outlet of oblique outer ejection.However, this range hood, its complex structure is relatively difficult with merging for existing lampblack absorber,
The feasibility for being applied to actual product is not high.
