Description

Fume barrier

This creation is about a fume barrier baffle group, especially one that can be assembled on both sides of the suction hood of the oil exhaust fumes to effectively prevent the leakage of soot pollutants, and is applicable to factories, laboratories and kitchens.

"Traditional oil-discharge soot" is not much different from the top suction suction hood generally used in the workplace. The flange of such oil-discharged soot may be a flat, downwardly arched or box-shaped shape, while the suction port may be round, square, rectangular or elongated. When such a range hood is inhaled, air and contaminants will flow from under the rim to the underside of the hood, into the suction port, and then through the conduit to the outside. Among them, the air flow rate near the position of the suction port is large, and the air flow rate away from the position of the suction port will rapidly decrease as the distance from the suction port increases. Therefore, within a short distance below the suction port, the speed of the air upwards has become small, so that the upward suction force is insufficient, and it is highly susceptible to disturbance airflow from the movement of people, fans or air-conditioning operations. Allows soot or contaminants to escape as the flow of disturbed air flows.

When the above-mentioned range hood is used in an environment that generates high-temperature gas, although a large buoyancy effect is generated due to the high temperature of the fire, the velocity of the ascending airflow is increased, but the turbulent diffusion and expansion effect due to high temperature , so that the soot pollutants can easily escape from the front, rear and side of the fume barrier group. Therefore, the general range hood often increases the suction In order to increase the amount of inhalation, however, this method will not only increase noise, waste energy, but also completely prevent leakage.

In view of the above problems, a common improvement method is as shown in Fig. 7, in which the baffles are respectively added to the left and right sides and the rear of the range hood a. However, in actual use, the boundary layer of the gas stream is easily separated at the leading edge of the two side plates b to generate a large return bubble c, which will roll the soot pollutants near the front edge of the two side plates b and diffuse through the molecules. Leaks with turbulent flow, or is exposed to the environment due to environmental disturbances. Furthermore, at the junction of the flange d of the range hood a and the side panel b, due to the three-dimensional effect, complex three-dimensional eddy currents and strong turbulence will be generated, and the pollutants will be rolled up to the exhaust hood a. Leakage occurs at the junction of the edge d and the side plate b. Therefore, simply adding the side plates b to the left and right sides of the range hood a can not completely achieve the effect of preventing leakage.

In view of this, in order to provide a structure different from the conventional technology and to improve the above-mentioned shortcomings, the creator has accumulated many years of experience and continuous research and development improvements, and this creation has not been produced.

One of the purposes of the present invention is to provide a fume damper baffle group structure which is provided with first and second vertical plates and left and right deflecting plates at the front ends of the left and right vertical plates, respectively, and can solve the conventional range hood. The leading edge of the side plate is prone to the problem of large backflow bubbles, and the large return bubble can be kept away from the front edge of the side plate to prevent leakage of contaminants.

One of the purposes of the present invention is to provide a fume barrier plate having left and right deflecting plates respectively at the front ends of the left and right vertical plates, and left and right top plates respectively at the upper portions of the left and right deflecting plates. The group structure can solve the problem of three-dimensional eddy current and strong turbulence at the junction of the flange and the side plate of the conventional range hood, and can keep the vortex away from the opening of the front end of the oil fume to prevent pollutants. leakage.

One of the purposes of the present invention is to provide a fume damper baffle assembly structure that can be assembled on both sides of a suction hood of a general range hood, which can be flexibly applied to a general range hood to reduce the need to repurchase the entire set of fume damper baffles. The cost of the range hood.

For upward pumping; the stack of fume barriers includes a left baffle and a right baffle. Wherein, the left barrier plate comprises a left vertical plate, a first vertical plate, a left deflecting plate and a left top plate, and a top connecting portion is provided at a top end of the left vertical plate for being coupled to the lower side of the left side surface of the suction cover, and the left vertical plate The front end is bent to the left to extend the first vertical plate, and the front end of the left vertical plate is bent to the right rear to extend the left deflecting plate to form a first angle between the left deflecting plate and the left side plate, and the free end of the left deflecting plate The upper part is bent to the right in the direction away from the left vertical plate.
