Description

Diversion structure of windshield

This creation is related to a diversion structure of a windshield, especially a windshield diversion structure that can prevent backflow caused by strong external winds, make the exhaust smoother, and prevent the accumulation of water in the exhaust pipe from affecting the exhaust effect.

Press; general range hoods or bathroom exhaust fans are usually attached to the top edge of the exhaust pipe to discharge the exhaust gas to the outside. In order to prevent the exhaust gas from being poured back by the external wind, it is usually installed on the end wall of the exhaust pipe A windshield is installed on the surface. The conventional windshield is shown in Figure 1. It is equipped with a fume exhaust hood 11, which is a hemispherical shell. The size of the fume exhaust hood 11 and the exhaust pipe The caliber of 12 is the same size, and the diversion mesh 13 is set at the joint of the two calibers. The spherical surface of the fume exhaust hood 11 has an exhaust port 14 facing the ground, and the indoor oil fume passes through the exhaust pipe 12. Passes through the guide mesh 13 and is discharged to the outdoors through the exhaust port 14. The outdoor wind and rain and foreign objects are blocked by the exhaust hood 11. Although the windshield can prevent the vertical inflow of external rainwater, due to the structural design Among them, the louver design of the guide mesh 13 makes the cross-sectional area smaller, resulting in unsmooth exhaust, and generating back pressure, which affects the indoor gas or oil fume emission effect. Furthermore, this kind of structural design makes it easy for strong outdoor wind to directly pour into the exhaust pipe or even into the room, which affects the exhaust effect, and may even cause the smoke and greasy phenomenon of the house due to poor exhaust. In view of this, after continuous research and experimentation, the applicant came up with a design of a windshield structure, which can prevent backflow caused by strong external winds, make the exhaust smoother, and prevent water accumulation in the exhaust pipe from affecting the exhaust effect.

The main purpose of this creation is to provide a diversion structure of the windshield for fixing to the end of the exhaust pipe of the range hood. With the barrier-free fully open and diversion design, it can prevent backflow caused by strong external winds. Qi is smoother.

The diversion structure of the aforementioned windshield is provided with a cover. The cover system at least includes a surrounding horizontal part and a vertical part connected to the horizontal part. The upper and lower edges of the horizontal part are respectively provided with a plurality of The upper vent hole and the lower vent hole, the inner edge of the vertical part is provided with a round protrusion with an appropriate circular diameter and an appropriate height. To match the cover with an inner frame for fixing on the wall at the end of the exhaust pipe of a range hood or bathroom exhaust fan, so that the exhaust gas can be discharged from the upper and lower exhaust holes through the diversion of the round protrusions , In order to prevent backflow caused by strong external wind, which helps the exhaust gas to be quickly diverted and discharged, so that the exhaust is smoother.

In the aforementioned flow guiding structure of the windshield, the round protrusion is protruded from the inner edge of the cover in an appropriate arc.

In the aforementioned flow-guiding structure of the windshield, the round protrusion can be a round protrusion-shaped disc body, and the disc body is fixed to the inner edge of the vertical part of the cover body.

Please refer to Figure 2 and Figure 3 at the same time, which are the three-dimensional and cross-sectional views of this creation. As shown in the figure, this creation is provided with a cover body 2, which at least includes a surrounding horizontal part 21 and a vertical part 22 connected to the horizontal part 21, making the cover roughly shaped like a round cap or a square cap. . Among them, the upper edge and the lower edge of the horizontal portion 21 are respectively provided with a plurality of upper vent holes 211, a first lower vent hole 212, and a second lower vent hole 213. The vertical portion 22 is provided with an appropriate circle. A round protrusion 221 with a diameter and an appropriate height. In this embodiment, the vent holes 211 provided on the upper edge of the horizontal portion 21 of the cover 2 are rectangular holes arranged at intervals; the first lower vent is located on the lower edge of the horizontal portion 21 of the cover 2 The hole 212 is a large rectangular hole. The second lower vent hole 213 is composed of a plurality of small rectangular holes; the round protrusion 221 is bulged from the inner edge of the cover 2 with a proper arc, which is also It can be a round protruding disk body, which is fixed to the inner edge of the vertical portion 22 of the cover body 2.

The cover 2 is matched with an inner frame for fixing on the wall at the end of the exhaust pipe of a range hood or bathroom exhaust fan, so that the exhaust gas can be guided by the round protrusion 221 to the upward exhaust hole 211 and the first The lower exhaust hole 212 and the second lower exhaust hole 213 are discharged to prevent backflow caused by strong external wind, which helps the exhaust gas to be quickly diverted and discharged, making the exhaust smoother.

Please refer to Figure 4, which is the assembly state diagram of this creation. As shown in the figure, when this creation is used, 3 sets of inner frames with a long hole 31 on the bottom edge are placed behind the cover body 2, forming a complete windshield A for installation and fixing on the range hood or The wall at the end of the exhaust pipe of the bathroom exhaust fan is connected with the exhaust pipe of the range hood.

Please refer to Figure 5 and Figure 6 at the same time, which are the state diagrams of the smoke exhaust action created for this creation. As shown in the figure, the windshield A of this creation is installed on the wall of the exhaust pipe end of the range hood or bathroom exhaust fan. When the exhaust gas of the range hood is discharged along the exhaust pipe 4, it will pass through first The inner frame 2 of the windshield enters into the cover body 2. As the inner edge of the cover body 2 is provided with a round protrusion 221, the exhaust gas is caused by the round protrusion 221 after touching the round protrusion 221. The arc surface diffuses outward in the circumferential direction, and the exhaust gas is respectively directed to the upper exhaust hole 211, the first lower exhaust hole 212, and the second lower exhaust hole 213 of the outer cover body 2 to discharge outwards, thereby helping the exhaust gas to be quickly diverted and discharged. , The oil or water contained in the exhaust gas drips down from the long hole 31 of the inner frame 3 to prevent it from accumulating in the windshield A. In this way, with the barrier-free fully open design, the exhaust will be smoother, and because the round protrusion 221 can prevent the oil in the exhaust gas from accumulating in the windshield A and the pipeline, so that the windshield A Maintain a good exhaust effect.

The foregoing embodiments are merely illustrative of the preferred implementation of this creation, rather than limiting the scope of this creation. All minor modifications and changes will still not lose the essence of this creation, nor deviate from the spirit of this creation.

To sum up, this creation uses a cover with upper and lower exhaust holes, and the round protrusions arranged on the inner edge of the cover form the diversion structure of the windshield for fixing to the exhaust fumes with an inner frame. The end of the exhaust pipe of the machine prevents backflow caused by strong external winds, and through the diversion of the round protrusion, it helps the exhaust gas to be quickly diverted and discharged, making the exhaust smoother. For a practical design, it is truly a creation of novelty. I file an application for a patent according to the law. I pray that the Bureau will review it and grant the patent as soon as possible, which is very convenient.
