Description

Ventilation hood airflow structure

The invention relates to a ventilating hood airflow structure, in particular to a method capable of providing indoor exhaust airflow to the outside, and can appropriately block the external upwind airflow from entering the room to avoid obstructing the original exhaust gas flow.

Generally, a plurality of air outlets are usually reserved in the structure of the building, and the air outlets can be used for various spaces or devices in the room, such as a kitchen hood air outlet or a bathroom air outlet. In this way, the indoor and outdoor air can be circulated and circulated, and the indoor air can be exhausted to the outside. However, if only the air outlet is provided at the outer wall of the building and there is no other shielding device, it will easily cause the wind and rain outside the house to be poured into the indoor environment. Therefore, the outer wall of these air outlets is usually equipped with an outer air hood, and the structure is mostly an elbow-shaped elbow, one end of which is disposed in the air outlet of the outer wall, and the other end is exposed outside.

However, the external air hood of this structure is easy to leak from the elbow exposed to the outdoor end due to the wind pressure of the outer wall, which causes the resistance to be excessively discharged when the room is to be exhausted, and cannot be discharged to the outside, but instead flows to the interior. Air quality in the home environment. In addition, in the case of violent storms and severe weather, such as typhoons, often accompanied by an abnormal spiral upward airflow, often the spiral rising airflow entrains rainwater through the curved pipe, which dirty the indoor environment. Therefore, it is necessary for the relevant industry to think further, how to improve and improve to be more in line with the use of the public.

In view of the above situation, the inventors invested a lot of time to research relevant knowledge, and compared various advantages and disadvantages, carried out research and development of related products, and conducted numerous experiments and tests, and finally introduced a "ventilation cover airflow structure" improvement. The above missing is in line with the needs of the public.

In order to achieve the above object and effect, the present invention provides a ventilating hood airflow structure, comprising: a cover body having an air guiding passage therein, and a bottom of the hood is provided with a flow guiding port and communicating with the air guiding channel; One side of the cover body is provided with a communication end, and one end of the communication end is connected to the other end of the air guide channel to communicate with the room, and the end face of the communication end is provided with a plurality of air guiding holes, and each air guiding hole is connected to the air guiding channel and the indoor, The cover body is provided with at least one venting hole, and the at least one venting hole is in communication with the air guiding channel; and a base is disposed at the inner edge of the air guiding opening, and the base is provided with a plurality of air guiding holes, And each of the air guiding holes is in communication with the air guiding channel, and the wall of one side of each of the air guiding holes has a guiding piece extending inward and upward; wherein the indoor air flow is diverted from the air guiding holes and the air guiding channel to each The diversion holes or the exhaust holes are discharged outward, and the rainwater entrained by the outdoor updraft is first blocked by the baffles and the baffles to prevent the rainwater from directly invading the outdoor wall by the influence of the rising airflow. In the gas passage, and the outdoor updraft is affected by Each of the guide fins, so that rising air upward along the guiding channel and outwardly through the respective vent holes.

According to a further feature of the present invention, a connector is further provided, and One end of the connecting member is disposed at the other end of the communicating end to communicate with the room.

According to a further feature of the present invention, the hole wall below each of the air guiding holes has a slanting guide piece extending outward in the direction of the communicating end and extending upward.

According to a further feature of the present invention, the cover body has a baffle extending outwardly from a side of the bottom end relative to the base, and the baffle is in the same lateral direction as the communication end.

According to a further feature of the present invention, the baffle extends from the wall of the flow guiding hole toward the air guiding passage.

According to a further feature of the present invention, the at least one venting hole is disposed at a top end of the cover.

Therefore, the present invention can be said to be a practical and progressive invention, which is quite worthy of promotion by the industry and is publicized to the public.

In order to clearly illustrate the above objects and effects of the present invention, the features and effects of the present invention will be described in detail with reference to the accompanying drawings. Please refer to the picture As shown in the first to sixth figures, the figure shows a ventilating airflow structure, comprising: a cover body 1 having an air guiding passage 11 therein, and a bottom opening 12 is provided at the bottom of the cover body 1 and The communicating body 13 is provided with a communicating end 13 , and one end of the communicating end 13 is connected to the other end of the air guiding passage 11 to communicate with the chamber, and the connecting end 13 is provided with a plurality of air guiding holes. 131, each of the air guiding holes 131 is connected to the air guiding passage 11 and the indoor, and the cover body 1 is provided with at least one venting hole 14, and the at least one venting hole 14 is connected with the air guiding passage 11; and a base 2 The group 2 is disposed at the inner edge of the air inlet 12, and the base 2 is provided with a plurality of air guiding holes 21, and each of the air guiding holes 21 communicates with the air guiding channel 11, and the wall of each of the air guiding holes 21 has a direction a guide vane 211 extending inwardly and upwardly; wherein the indoor airflow is diverted from the air guiding holes 131 and the air guiding passages 11 to the respective guiding holes 21 or the exhaust holes 14 to be discharged outward, and the outdoor rising air is entrained The rainwater is first blocked by the baffle 3 and each baffle 211 to prevent the rainwater from being directly affected along the outdoor wall by the updraft. Invasive guiding channel 11, and is guided outside the updraft of each baffle 211, so that rising air along the air guide passage 11 is discharged upwardly and outwardly through the respective vent 14.

The foregoing is a main technical feature of the main embodiment of the present invention, which corresponds to the content of the first item of the patent application scope of the present application, and the object and the implementation form of the present invention are known in detail, and the technical features described in the remaining subsidiary patent scopes are The detailed description or additional technical features of the first content of the patent application scope, and not to limit the scope of the first paragraph of the patent application scope, it should be noted that the first item of the patent application scope of the present application does not necessarily include the scope of the remaining subsidiary patents. Technical characteristics.

It is worth mentioning that a plurality of vent holes 14 are provided at the top end of the cover body 1 and are in communication with the air guiding passages 11, and each of the vent holes 14 is in the form of a long transverse direction. In addition, the cover body 1 has a baffle 3 extending outwardly from a side of the bottom end opposite to the base 2, and the baffle 3 is disposed on the same side of the communication end 13 and is located at each of the guide holes 21 of the base 2. The side baffle 211 extends from the hole wall of the air guiding hole 21 toward the air guiding channel 11, and the hole wall below each air guiding hole 131 has a slanting guide 4 extending upward toward the outer side of the communicating end 13 (eg, Figure 2 and Figure 4).
