New description: [New technical field] This creation is related to a kind of range hood, especially a kind of disturbing airflow from all directions to eliminate soot pollutants and prevent soot and harmful gases from outward. Maolu, suitable for use in home kitchens, restaurant kitchens and other workplaces that generate polluting gases. [Prior Art] The "traditional kitchen hood" is not much different from the top suction hood that is used in the workplace. In the green (four) distance of the suction port, the speed of the fluid upwards has become very small, so that the upward grapefruit is insufficient in suction, so it is very easy to be driven by people walking around, fans or air-conditioning. The effect of the moving airflow makes the effective soot capture _ into a very small range. In this way, the soot near the suction port will escape the flow of the disturbing airflow, which will endanger the health of the kitchen cooker. Therefore, the creator has used the principle of gas dynamics to develop a range hood with a "gas curtain" to overcome the above problems. The main technical details are the forward forging of the flow-stage, the airflow that is blown back obliquely upwards, and a slit-shaped suction hood above the table, and the left and right sides of the table top are completely transparent. Empty as a qi, use, and make the airflow of blowing and suction form a nearly two-dimensional air curtain. This scale, which conforms to the aerodynamic principle, will cause the soot and toxic gas between the oblique and the back wall to be discharged to the upper suction hood by the airflow. When implemented, the above-mentioned range hood can effectively remove and block soot and harmful gases without strong disturbance of |L airflow, and can move people in front of the flow table and slightly disturb the airflow (about 2〇) The disturbance speed below cm/s) causes the 3 M440418 to have a long and narrow grapefruit mouth, and a long vertical plate structure is arranged under the left side, the right side surface and the rear end surface of the suction hood, which can block the coming from The lateral disturbance of the airflow creates a complete upward directed airflow to remove soot and harmful gases and prevent soot and harmful gases from leaking out under the rear end face of the suction hood. The secondary purpose of this creation is to provide a range hood with a structure that can be seen through the rear end face of the suction hood with a see-through elongated vertical plate that can be used in an island-mounted kitchen when the range hood is used. Can form a line of sight to create a wide visual effect. For the purpose of the above creation, the hood of the creation is located above the platform _ above the platform of the platform is provided with a gas generating device, and the hood includes a suction hood and a rear hood A plate, an elongated left vertical plate and an elongated right vertical plate.

When implemented, the back panel is a see-through panel. In order to facilitate a deeper understanding of the creation, it is described in detail later: [Embodiment] 凊 Refer to Figure 2, which is a preferred embodiment of the creation of the range hood i, the rear end face is installed in a wall 11 is located above a platform 12, and the platform 12 is provided on the table top. The upper part of the platform 12 can be provided with a head, and the head is set as a production rolling device 13, and t, the gas generating device 13 faces the wall. One side of the eleven is defined as the rear ten edge 131' and the opposite side of the trailing edge 131 and away from the wall u is defined as the leading edge 132. In practice, the gas generating device 13 may also include a pot or other appliance that can generate harmful gases. The range hood 1 includes a suction hood 2, an elongated left vertical plate 3, an elongated right vertical plate 4, and a rear plate 5. The suction hood 2 includes a wind collecting box 21 which is a substantially rectangular housing having a space 2U formed therein, and the bottom plate 212 of the wind collecting box 21 is provided with parallel and narrow sides. a suction port 22 with a downward opening and a narrow blowing groove 221 ' with a downward opening and a narrow suction port 22 and a blowing groove 221 are located between the front end face 23 and the rear end face 24 of the suction hood 2, and The front end face 23 and the rear end face 24 are parallel. The elongated air blowing slot 221 is in communication with an air blowing device 222 for blowing air downward; in practice, the air blowing device 222 is a blower or a cross flow fan, and as shown in the figure, the narrow length The shape blowing groove 221 may also be composed of a left blowing air groove 2211 and a right blowing air groove 2212 which are located on the same straight line; or the elongated blowing groove η, the left blowing air groove 2211 or the right blowing air groove 2212 is formed by arranging a plurality of spaced air holes. In addition, the bottom surface 212 of the wind collecting box 21 is provided with an oil absorbing frame 213, and the oil retaining frame 213 is protruded from the surface of the bottom plate 212, and is framed under the narrow suction port M440418 i. The box 25 can also be disposed below or at the side of the front end of the board of the thief board 212. The top surface of the wind box 21 is connected to the upper side through a suction inlet 214 and the inlet 214 is offset from the narrow suction port. The upper fluid machine i ^ pumping 26 of the system is implemented by a fan, a blower or other pumpable map, and the wind box 21 can also be a generally bell-shaped housing, and 3 Bribe money σ 22 fine _ stealing; as shown in Figure 4, the narrow to suction port 22 is oriented away from the rear end face ^ of the wind box 21. The glazed surface-shaped vertical plate 3 has a substantially rectangular shape, and its top end is fixed below the left side of the wind collecting box 21 so as to extend downward from the lower side of the left side surface of the wind collecting box 21, and to make the long left vertical tσ 22 _ straight. _ Zuo Xiong 3 _ right-side diversion section 31, the elongate left vertical (four) horizontal width w is not small: the horizontal distance w between the trailing edge 131 of the oxygen set 13 to the wall u, that is, the long 2 vertical plate 3 At least the phase block of the money device 〖3; and the length of the long façade H is not less than the top end of the platform 12 to the bottom end of the elongated left vertical plate 3, the long right vertical plate 4 and the long left The left and right sides of the plate 3 __ bellows 21, the top end of the elongated right vertical plate 4 is fixed below the right side surface of the wind collecting box 21 so as to be extended by ==ΤΓΤ and the elongated right vertical plate 4 and the elongated shape are drawn In addition, the left side of the front end of the elongated right vertical plate 4 is provided with a curved shape 2 - a guide 41 '. The horizontal width of the elongated right vertical plate 4 is not less than the level between the gas generating device 13 and the edge 131 to the wall U. The distance, that is, the elongated right vertical plate 4 at least blocks the right side portion of the gas generating device 13, and the length M440418 of the elongated right vertical plate 4 is not less than a flat (four) top end to an elongated right vertical plate. 4 the height of the bottom end. In this way, the front end surface of the elongated left vertical plate 3 and the lower end of the left side surface of the suction hood 2 are formed into a substantially rectangular first air supply clock 27, and the rigid end surface of the elongated right vertical plate 4 and the suction hood A lower portion of the front end of the right side surface of the second portion is formed as a second rectangular air supply portion 8 having a substantially rectangular shape. And a third qi space 29 is formed between the bottom end of the left vertical plate 3 and the left side of the platform 12, and the bottom side of the right vertical plate 4 is connected to the right side of the impact η. The fourth complement of the rectangle is %. The rear plate 5 is a rectangular flat plate whose top end is fixed under the rear end surface 24 of the wind collecting box 21. The length of the vertical surface of the rear plate 5 is not less than the height of the platform 12 to the bottom end of the rear plate, and the left side of the rear plate 5 The surface abuts the rear end surface of the elongated left vertical plate 3, and the right side surface of the rear plate 5 abuts the rear end surface of the elongated right vertical plate 4. Thereby, as shown in Figures 5 and 6, when the creation is fixed on the biliary wall and the gas generating device 13 starts to generate soot or other harmful gas, the operation of the suction device will cause the elongated suction π 22 _ upward Pure, and through the high-speed gettering action of the narrow-shaped domain port 22, an oblique airflow is formed below the front end of the wind collecting box 21 to drive the soot or other Wei body rise generated by the gas generating device 13 and After passing through the space 211 inside the wind (4), it is discharged to the outside through the air suction device 26. Since the suction inlet 214 of the air extracting device 26 is offset directly above the elongated suction port 22, the accumulated waste oil will not directly be bribed, and the domain is on the surface of the bottom plate 212. Since the oil retaining frame 213 is framed around the narrow suction port r for four weeks to block the waste oil from dripping downward from the suction groove 22, the waste oil flows downward into the oil storage case 25. Due to the _ of the elongated left vertical plate 3 and the elongated right vertical plate 4, the disturbing airflow in the lateral direction can be resisted to prevent the oblique airflow structure from being damaged, and the barrier of the rear plate 5 can be prevented. The soot or other harmful gas is Γ from the left side of the M440418 24 of the windbox a to the left side of the left vertical plate 3 and the right side of the long standing plate 4, thereby (4) complete upward air flow, and the oil smoke and harmful gases are removed. When implemented, the rear panel 5 can also be a see-through panel. When the creation is installed in the kitchen of the island=configuration, the effect of visual penetration can be produced in addition to the sifting of soot or other harmful gas. Furthermore, since the front end of the left vertical plate 3 is provided with a curved first flow guiding portion 31, and the left side of the front end of the right vertical plate 4 is provided with a curved second guiding flow correction, when the air passes through the first-intake section When the seventh and second air supply ducts 8 enter the space below the wind collecting box 21, the separation points (3U, 411) of the air fluid from the first flow guiding portion 31 and the second flow guiding portion 41 are delayed. In this way, the return flow created by the air fluid can be reduced to ensure a smooth exhaust flow. As shown in FIG. 7, when the gas generating device 13 generates a high-temperature gas, the phenomenon of the gas expansion will cause the soot to diffuse toward the front end surface 23 of the suction hood 2, and the air blown downward by the blowing groove 221 at this time may be The high temperature inflation gas is prevented from escaping from the front end of the bottom portion of the suction hood, and the high temperature gas is guided to enter the narrow suction port 22 to prevent the exposed gas line from being exposed. Therefore, 'this creation has the following advantages: 1. This creation uses the narrow-shaped suction port to carry out the pomelo gas, and the long left and right vertical plates block the disturbing airflow from the lateral direction. Therefore, a complete upward guide can be formed. Introduce airflow to remove soot and harmful gases. 2. This creation system reduces the backflow bubble entering the space under the suction hood by the flow of the front end of the elongated left and right vertical plates. Therefore, it is possible to prevent the backflow bubble from protruding outward and the soot is easily diffused and affected. The integrity of the gas flow is directed upwards to ensure that Figure 7 is a diagram of the state of use of the gas producing apparatus of the preferred embodiment of the present invention in the production of high temperature gases.
