Description

Hood-guided fume exhaust device

This creation relates to a fume extraction device, and more particularly to a hood-oriented exhaust fume device.

Press, when cooking food in the kitchen, especially in the process of frying and frying, soot is often produced. Fume can adhere to walls or kitchen utensils, and it has a major disadvantage of causing mess and becoming a breeding ground for bacteria or pests. On the other hand, soot has a major impact on human health and may cause diseases in the lungs or trachea. Therefore, how to export soot in the cooking process becomes an important issue.
A prior art such as the new patent No. M483393 in China, which uses the top plate of the baffle plate and the deflecting plate to generate a large backflow, and pushes the soot to the inside and the upper part, but the propulsion force is weakened in the middle part, so the soot is difficult to be completely restricted to the left. In the right barrier, the soot will still scatter from the front and rear of the stove, causing the above problems. In addition, the conventional structure adopts a fixed left and right baffle plate, which is not only less beautiful, but also hinders the user's cooking action.
The second prior art, such as China's new patent publication No. 582530, is mainly to provide a jet flow discharge device around the stove, and a gas wall can be formed between the stove and the range hood to separate the inside and outside air, and then the soot The suction range sent to the range hood. However, there is no obstruction structure at the rear of the stove, so the surrounding wall and the surrounding area will cause the problem of soot pollution, and the thrust of the gas wall forming the end of the jet gas is insufficient, and the soot will still be scattered around.
The third prior art, such as the Chinese invention patent No. I375776, utilizes a smoke exhauster casing that is inclined from the middle to the left and right sides, so that the soot flows toward the middle and is discharged to the outside by the smoke exhaust port. However, the distance from the smoking port to the stove of this conventional structure is still too long, so that the suction end of the exhaust fan of the range hood is insufficient, and the soot will still be scattered toward the surroundings.
The fourth prior art, such as the invention patent No. I361263 of China, its main mechanism includes a blowing device, a suction hood, a long suction end and a long blowing end, so as to make a long pumping when the air pump is running. A two-dimensional oblique air curtain is formed between the end and the long blowing end to eliminate the fumes between the inclined single air curtain and the wall to reduce the dissipation of contaminants. However, the wall behind the device will cause serious dirt pollution, and the blowing force of the airflow from the air blowing end will be insufficient in the second half of the flow, which will still cause the oil smoke to scatter around.
The fifth prior art, such as the Chinese invention patent No. I409420, is mainly composed of components related to storage, and the top cover, the blower, the waste guide plate and the ventilation contact portion are connected to the exhaust through the left guide plate. The enveloping effect causes the fumes to be discharged from the exhaust vent. However, the soot will scatter from the back, front and right sides of the conventional structure, which will also cause pollution of the walls and the surrounding environment.

The main purpose of the present invention is to provide a hood-guided fume exhausting device which utilizes a gas flow to form an invisible gas wall and is combined with a solid cover to form a channel for guiding the soot, thereby achieving the effect of preventing the flue freely dispersed. .

Please refer to Figures 1 and 2 for the hood-oriented fume extraction device provided by the creation, which is arranged in conjunction with a stove 1 to guide the use of the stove 1 to produce soot when cooking food. The exhaust fume device comprises a row of hoods 2, a jet ring 3, a cover 4 and at least one blower 5. The details are as follows.
The range hood 2 is disposed above the stove 1 and has an air suction port (not shown) and an air outlet 21 from which the soot can be sucked and discharged from the air outlet 21. The air ring 3 is formed in a ring shape and surrounds the periphery of the stove 1. The inside of the air ring 3 is provided with a first-class track (not shown), and the flow path is provided with at least one air inlet 31 on the circumferential side of the air ring 3. In the present embodiment, two air inlets 31 are provided on the circumferential side of the air ring 3. The flow path is further provided with a plurality of gas outlets 32 on the top surface of the jet ring 3, wherein the gas outlets 32 are arranged along the jet ring 3 to form a ring shape.
The blower 5 is connected to the air inlet 31 of the air ring 3 by a supply duct 51. In the present embodiment, the number of the blowers 5 is two, and is respectively disposed on the left and right sides of the range hood 2. Each of the blowers 5 is connected to the intake port 31 of the jet ring 3 in a one-to-one manner by a blow pipe 51. The blower 5 is for generating an air flow, and the air flow is input into the air ring 3 via the air supply duct 51. When the airflow is input into the air ring 3, it flows in the flow path of the air ring 3, and is ejected upward from each of the air outlets 32 to form a ring-shaped air wall.
The cover body 4 has a connecting end 41 and a control end 42. The connecting end 41 is provided with a fixing portion 43 for fixing the connecting end 41 to the air inlet of the range hood 2; The fixing portion 43 may be a screw. The cover 4 is of a retractable structure, and the expansion and contraction of the cover 4 can be controlled by operating the control end 42. On the structure of the detail, a handle 44 is respectively disposed on both sides of the control end 42 for the user to pull the cover 4 through the handles 44, thereby pulling the cover 4 downward. After the cover 4 is elongated, the bottom end is still at an appropriate distance from the stove 1.
With the above configuration, after the air blower 5 inputs the airflow into the air-jet ring 3, as shown in FIGS. 3 and 4, the airflow is ejected from the air outlet 32 of the air-jet ring 3, since each of the air outlets 32 is formed in a circular arrangement, The peripheral side of the oven 1 produces an invisible annular wall 6 whereby the space between the inside and the outside of the wall 6 can be isolated. On the other hand, when the cover 4 is pulled down, the cover 4 and the annular gas wall 6 are coupled to each other to form a passage for guiding the soot, thereby guiding the soot to the range hood 2. In actual use, when the soot is generated and raised on the stove 1, it is restrained by the gas wall 6 and cannot be scattered toward the side, and can only float upward along the exhaust passage formed by the gas wall 6. After entering the cover 4, it is restrained by the physical structure of the cover 4, and is less likely to be scattered toward the side, and finally sucked by the range hood 2.
The advantages of this creation are:
First, the environment is clean and hygienic: the cover body 4 and the gas wall 6 form a closed exhaust passage, the catching efficiency of the soot can reach more than 98%, so the kitchen wall, ceiling, stove, dining table, cabinet and kitchen Most of the other equipment will not be contaminated with oil, which will keep the overall environment clean and hygienic.
Second, the protection of human health: Same as above, because the capture efficiency of soot is high, users will not inhale hazardous fumes during cooking, to avoid harm to human health.
Third, extend the life of the stove: Because the capture efficiency of the soot is high, soot or grease will not splash to the stove 1 below, so the service life of the stove 1 can be effectively extended, reducing the repurchase for the user The cost of the stove.
4. The operation is simple and convenient: the user only needs to pull down the cover 4 to connect to the gas wall 6 generated by the jet ring 3 to form a passage for guiding the soot; on the other hand, the gas wall 6 is invisible. The air is formed, so it is very convenient without hindering the user's cooking action.
However, the disclosure of the above embodiments is intended to illustrate the present invention and is not intended to limit the present invention, so the replacement of equivalent elements should still be within the scope of this creation.
In summary, it can be made clear to the skilled person that the creation can achieve the aforementioned objectives, and it has already met the requirements of the Patent Law and submitted an application according to law.
