In addition, through the eaves above the discharge hole, insects, foreign objects and rainwater can be drained out to avoid entering the fume discharge hood, and the opposite sides of the ㄇ frame surround are provided with a plurality of guides And the exhaust ports with multiple openings facing backwards, as the openings of the exhaust openings are facing backwards and are covered by the guide pieces, the same also has to keep insects, foreign objects and rainwater out to avoid entering the fume exhaust hood The effect within.

Description

Fume exhaust hood

This new creation is about a cover body, especially a fume exhaust cover.

Because the indoor air is often closed, it needs to communicate with the outdoor to improve the indoor stagnant heat, scorching heat, or oil fume, especially the oil fume produced during the cooking process must be discharged. In the process of discharge, on the one hand, it is necessary to achieve internal and external communication, on the one hand, it is necessary to avoid the wind/rain from the outside. Therefore, the industry has designed a fume exhaust hood, which is used as an emission, while avoiding the entry of external wind/rain or mixed dust. In general, the general oil fume discharge hood is mainly used for guiding a fume discharge pipe. The main body includes an outer plate (A1), and a frame panel (A2) is provided on the edge of the outer plate (A1). In order to allow the release of hot gas and gas, designers often provide a plurality of holes (A3) on the left and right opposite sides of the frame enclosure (A2) to prevent the infiltration of wind/rain, and the rainwater that will enter the fume discharge hood 、Foreign matter and insects are discharged, a discharge port (A4) will be provided at the bottom of the frame enclosure (A2). However, since the characteristics of the smoke are naturally upward, the above-mentioned conventional fume exhaust hood will prevent the smoke from being discharged upwards, resulting in a poor overall exhaust effect. In this regard, the creator of this new model believes that this problem really needs to be improved and starts thinking about the way to improve.

In view of the deficiencies described in the prior art, the creator of this new type proposes a solution, which relates to a fume hood, including: On the back side of a plate body, there is a ㄇ-shaped frame enclosure with an opening facing down. The opposite sides of the ㄇ frame-shaped enclosure are provided with a plurality of exhaust ports, and a guide plate is provided on the edge of each exhaust port. The guide plate and the frame-shaped frame surrounding sheet respectively define an exhaust port with the opening facing backward, and a discharge hole is arranged on the top surface of the frame-shaped frame surrounding sheet and an eave sheet is arranged above the discharge hole. In this way, through the above-mentioned structure, the oil fume discharge hood can discharge the oil fume generated in the room upward through the discharge hole to improve the overall efficiency of the oil fume discharge. In addition, through the eaves above the discharge hole, insects, foreign objects and rainwater can be drained out to avoid entering the fume discharge hood, and because the opening of each exhaust port faces backward, the same 、Foreign matter and rain water are drained out to avoid the effect of entering into the fume exhaust hood.

The structure, characteristics and embodiments of the new creation will be explained below with the aid of the drawings, so that your reviewers will have a better understanding of the new creation. Please refer to the first picture, this new creation is about a fume hood, including: One board (1): As shown in the first picture, when the creative cover is installed at the fume exhaust port, the side facing the fume exhaust port is defined as the rear side, and otherwise the front side. One round frame frame (2): Please refer to the first figure, the ㄇ frame frame sheet (2) is arranged on the back side of the plate body (1) with the opening facing down, and the opposite sides of the ㄇ frame frame sheet (2) are provided with a plurality of rows For the air port (21), please refer to the second figure. Each exhaust port (21) is provided with a guide plate (22) at the edge, and each guide plate (22) is surrounded by the frame The sheet (2) jointly defines the exhaust port (21) with the opening facing backward, so that each exhaust port (21) also has the function of draining insects, foreign objects and rainwater through the guide plate (22) to The effect of avoiding entering the fume exhaust hood. The top surface of the frame frame sheet (2) is provided with a discharge hole (23), so that the original oil smoke generated in the room can be discharged upward through the discharge hole (23) to improve the overall efficiency of the oil smoke discharge. In addition, an eaves piece (24) is provided above the discharge hole (23), which can discharge insects, foreign objects and rain water to avoid entering the fume discharge hood. So, through the above, we can see that this creation has the following advantages: 1. Improve the efficiency of oil smoke emission: Since the characteristics of the fume are naturally scattered upwards, the creation of the discharge hole on the top surface of the frame frame helps the fume discharge to improve the overall fume discharge efficiency. 2. Prevent insects, foreign objects and rain from entering the fume exhaust hood: When rainwater, insects, and foreign objects want to enter the fume exhaust hood, the eaves piece (24) and the guide plates (22) can produce a blocking effect. In summary, this new creation is indeed in line with industrial utilization, and it has not been seen in publications or public use prior to the application, nor is it known to the public, and it is non-obvious and easy to understand, and meets the requirements of patentability. Application. However, what has been stated above is a preferred embodiment of the new creation in the industry, and any equal changes made in the scope of patent application for this new creation are within the scope of the appeal of this case.
