Referring to fig. 1 to 3, in the present embodiment, a smoke collecting hood 100 is fixedly disposed at a lower side of the smoke collecting hood inclined plane air curtain device, the smoke collecting hood 100 has an opening 110, and the opening 110 provides oil smoke to enter the interior of the device for purification treatment and discharge. The smoke-collecting hood 100 includes a far end 120 and a near end 130 which are oppositely disposed, the far end 120 referring to that when the smoke-collecting hood ramp curtain device is installed in a kitchen or other place, when a user cooks, the end of the smoke-collecting hood ramp curtain device far away from the user is the far end 120, and correspondingly, the end close to the user is the near end 130.
More, the inclined air curtain device of the smoke collecting hood of the embodiment can be installed on a wall and can also be used in the environment of a kitchen.
Referring to fig. 2, the exhaust hood 100 is provided with an exhaust plate 200 at the lower inner side near the man end 130, which is equivalent to the exhaust plate 200 provided at the lower position near the inner side of the exhaust hood 100 near the opening 110, and the exhaust plate 200 is provided with a first air curtain hole group 300. The orientation of the first air curtain hole group 300 is controlled by adjusting the distribution of the air outlet plate 200 in the smoke collecting hood 100, so as to increase the temporary storage area of the oil smoke.
Referring to fig. 1, the inclined air curtain device of the fume collecting hood has a longitudinal section 400, and the longitudinal section 400 is distributed along the vertical direction of the far end 120. The longitudinal section 400 corresponds to a plane obtained by splitting the exhaust fume collecting hood inclined plane air curtain device along the vertical direction from the user to the installed wall surface. The lowermost end of the inner side of the distal end 120 and the lowermost end of the inner side of the proximal end 130 have a first direction 500 on the longitudinal section 400, the air outlet panel 200 is distributed on the longitudinal section 400 along a second direction 600 which is upward, and the first direction 500 and the second direction 600 are arranged at an acute angle.
Referring to fig. 4 and fig. 6 in combination, fig. 4 and fig. 6 are partial schematic views of the air-out plate 200 on the longitudinal section 400, in which the air-out plate 200 has an extending direction, that is, the air-out plate 200 extends and is distributed along the straight direction, and the upward direction of the straight direction is the second direction 600.
Please refer to fig. 3 for a smoke blocking area corresponding to an existing air curtain hole. The existing air outlet plate 200 of the first air curtain hole set 300 is disposed in a manner equivalent to a manner under the condition that the first direction 500 is perpendicular to the second direction 600, when the first direction 500 is perpendicular to the second direction 600, the direction of the first air curtain hole set 300 is parallel to the first direction 500, at this time, the air coming out from the first air curtain hole set 300 moves from the far end 120 to the near end 130 along the first direction 500, so as to form an existing air curtain wall, and the spatial area of the air duct 800 enclosed by the air curtain wall in the inclined air curtain device of the smoke collecting hood is the current temporary storage area of the oil smoke. Wherein fig. 4 shows a relationship of the existing oil smoke blocking area in which the air outlet plate 200 is perpendicular to the first direction 500.
In the present embodiment, the first direction 500 and the second direction 600 form an acute angle, please refer to fig. 6. The second direction 600 generates a rotation angle compared to the prior art, with the first direction 500 not being the reference direction. The air outlet direction of the first air curtain hole group 300 is perpendicular to the second direction 600 of the air outlet plate 200, i.e. the process that the original air outlet direction is parallel to (coincident with) the first direction 500 is changed into the process that an included angle exists. The air-out direction of first air curtain pore group 300 rotates the skew downwards this moment, has enlarged original oil smoke temporary storage area to obtain bigger oil smoke temporary storage area, thereby can hold more oil smoke gas at the same time, improve kitchen environmental pollution's problem.
More specifically, referring to fig. 6, when the second direction 600 rotates (counterclockwise in the figure), the included angle between the first direction 500 and the second direction 600 is an acute angle, and the included angle decreases with the rotation. When the second direction 600 is rotated continuously, so that the air outlet plates 200 are arranged in parallel in the longitudinal section 400, until the second direction 600 is approximately coincident with the first direction 500, the obtained temporary storage area of the oil smoke is in the maximum state, but the blocking capacity (suction capacity) of the temporary storage area of the oil smoke to the oil smoke is also the weakest. When the second direction 600 continues to rotate in the same circumferential direction, the first direction 500 and the second direction 600 are obtuse-angled, which does not satisfy the above-mentioned acute-angled arrangement of the first direction 500 and the second direction 600.
More, when the first direction 500 and the second direction 600 form an obtuse angle, the first air curtain hole set 300 is discharged in a direction perpendicular to the second direction 600 toward the air duct 800, so that a smaller temporary oil smoke storage area is obtained, and the oil smoke is locked in the smaller area.
Further, referring to fig. 2, the first air curtain hole set 300 includes a plurality of air curtain holes, the air-out plate 200 is disposed along the inner side of the lower portion near the human end 130, and the plurality of air curtain holes are uniformly disposed on the air-out plate 200 in a penetrating manner along the distribution direction of the air-out plate 200. A plurality of air curtain holes are arranged on the air outlet plate 200 at certain intervals in sequence, and an air curtain with strong stability can be provided.
More specifically, referring to fig. 1, the present embodiment provides a method for arranging a smoke collecting hood 100 in the smoke collecting hood inclined plane air curtain device. Specifically, the lower end of the fume collecting cover 100 is rectangular, the lower end of the fume collecting cover 100 is provided with an opening 110, the two ends of the lower end of the fume collecting cover 100, which are different from the far end 120 and the near end 130, are respectively a left end and a right end, and the left end and the right end are both provided with a second air curtain hole group 700. Accordingly, the left and right ends are provided with the second air curtain hole group 700 at the lower inner side. Wherein the left end and the right end are arranged in a mode of being parallel to each other, which is favorable for the stability of the space region enclosed by the exhaust fume collecting hood 100 under the condition of air outlet. The second air curtain hole set 700 and the first air curtain hole set 300 are matched with each other to exhaust air together to form a temporary oil smoke storage area.
Further, referring to fig. 3 and 5, an air duct 800 is disposed in the oblique air curtain device of the smoke collecting hood, the air duct 800 is communicated with the opening 110, and the oil fume collected in the temporary oil fume storage area moves into the air duct 800 through the opening 110 to be purified and discharged correspondingly.
To sum up, the utility model discloses to some produce a large amount of oil smoke in the twinkling of an eye and lock the oil smoke better, only through the angle setting that changes air-out plate 200, and then change the air-out direction of first air curtain punch combination 300, just obtain bigger oil smoke temporary storage area, can hold more oil smoke gas at the same time, improve kitchen environmental pollution's problem.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
