Problems solved by technology

[0005] However, the air blown out from the air supply port will gradually weaken the effect of the air curtain during the descent process, and diverge as the distance away from the air supply port 7 increases, see Figure 2, without the suction of the exhaust fan, it is usually a trapezoidal cross-section Divergent air curtain ( Figure 2a ) or drop-shaped cross-section air curtain ( Figure 2b ), under the action of the suction of the exhaust fan 5, the trapezoidal cross-section divergent air curtain or the water-drop-shaped cross-section air curtain deflects to the bott

Embodiment 1

[0055] Figure 5 (a) shows an embodiment of the air supply opening with an inwardly expanding inner side, in which: on the bottom wall of the smoke collecting hood 4 at the lower inner side of the air supply opening, a curved baffle 8 is provided; in Figure 5 (a) In the specific embodiment shown in (a), the arc-shaped deflector is a semi-arc deflector, and the deflector can be injection molded into a hollow plastic or metal part. The deflector 8 is curved downward from the air supply cavity 6 and toward the inner working area of ​​the smoke collecting hood. The tangent direction of the deflector toward the air supply port is 5-35° from the vertical. Is 5-10°. The outer side wall 10 of the air supply outlet is a vertical plane, preferably set as a plane inclined toward the working area, and the angle between the outer side wall inclined toward the inside of the hood and the vertical plane is 5-20°, preferably Is 5-10°. The purpose of this arrangement is to make the wind curtain incl...

Embodiment 2

[0057] Figure 5(d) shows a second embodiment of the air outlet with an inwardly expanding inside, in which: on the bottom wall of the smoke collecting hood 4 at the lower part of the air outlet, a curved baffle 8 is provided; in the figure In the specific embodiment shown in 5(d), the curved baffle is a semi-circular arc baffle, and the baffle 8 is curved downward from the air supply cavity 6 and toward the inside of the smoke collecting hood. , The tangent direction of the arc surface of the baffle facing the air supply opening is 5-35°, preferably 5-10° from the vertical. The outer side wall 11 of the air supply port is a vertical plane, and is preferably set as a plane inclined toward the inside of the hood. The angle between the outside side wall inclined toward the inside of the hood and the vertical plane is 5-20°, preferably It is 5-10°, the outer side wall 11 extends downward from the end of the smoke collecting hood 4 to the lower end of the curved baffle, and the plane o...

Embodiment 3

[0059] Figure 5(e) shows a third embodiment of the air supply opening with an inwardly expanding inside, in which: on the bottom wall of the smoke collecting hood 4 at the lower part of the air supply opening, a curved baffle 8 is provided; in the figure In the specific embodiment shown in 5(e), the arc-shaped baffle is a 1 / 4 arc baffle, and the baffle 8 is formed downward and toward the inside of the smoke collecting hood from the air supply cavity 6 The arc surface is curved, and the tangent direction of the arc surface of the deflector toward the air supply opening is 5-35°, preferably 5-10° from the vertical. The outer side wall 10 of the air supply port is a flat surface, and is preferably set as a plane inclined toward the inside of the hood. The angle between the outside side wall slanted toward the inside of the hood and the vertical plane is 5-20°, preferably 5-10°. The purpose of this setting is to make the wind curtain inclined inward to facilitate the formation of an a...

Abstract

The present invention provides one kind of kitchen fume sucking wind curtain method and corresponding kitchen fume exhauster. Narrow slot is formed in the edge of at least one side of the kitchen fume collecting hood to spray air flow forming wind curtain inwards deviating to the work area, with the inwards deviating airflow being turbulent airflow formed with the so-called arced inwards airflow or laminar airflow formed with multiple nozzle thin airflow. Meanwhile, the exhauster of the kitchen fume exhauster makes the kitchen fume rolled into the exhauster. The kitchen fume exhauster can form separating wind curtain between the cook and the fume while exhausting kitchen fume effectively.

Description

Technical field [0001] The present invention relates to a method for sucking and discharging oil fume by an air curtain and a range hood adopting the method. Specifically, the present invention is an air curtain formed by using laminar, turbulent or divergent airflow towards a working area, and is compatible with the prior art The suction power of the conventional exhaust fan entrains the oil fume to be sucked and discharged, and forms an air curtain between the oil fume and the user, so that the oil fume does not enter the user’s area due to the divergence of the airflow, and is used to achieve the Method of extractor hood. Background technique [0002] Cooking food will produce a lot of oily fume. The absorption of oily fume by the human body will harm your health. The earlier range hoods are generally passive range hoods, that is, an exhaust fan is set in a certain position in the range hood shell, and the bottom center of the fume hood The suction port is set, and the oily fu...
