Description

Roof heat dissipation and ventilation cover structure

The invention relates to an indoor heat dissipation and ventilation structure, especially a roof heat dissipation and ventilation cover structure.

According to the theory, the existing tin houses usually install ventilators and other equipment on the roof of the factory to exhaust the stuffy air from the factory, increase the coolness and comfort inside the factory, and avoid the accumulation of hot air in the factory. The discomfort of the staff.

However, the common vent hood structure currently on the market is to erect a vent hood on the roof. The roof is provided with a preset exhaust vent, and an exhaust fan can be installed inside the exhaust vent. Using the internal design of the exhaust hood, It can not only achieve indoor heat dissipation and ventilation effects when the exhaust fan is actually in operation, but also prevent rainwater from entering the room and maintain the drainage function of the ventilating hood.

However, when the above-mentioned ventilation hood is installed and used, since the ventilation hood is fixed on the outside of the roof, and the roof is only preset with an exhaust vent and an exhaust fan installed inside the exhaust vent, the exhaust fan is directed toward the room to guide and exhaust air. As a result, the type of air that is preferentially discharged cannot be controlled when the exhaust fan is activated, so that cold air and hot air are discharged equally, reducing the amount of cold air and the time spent in the room, greatly reducing the efficiency of heat dissipation and ventilation of the hood, and lacking practicality In addition, when the exhaust fan is replaced or repaired, the exhaust fan can only be disassembled and installed from the room up due to the difficulty of dismantling the exhaust fan. The operator is looking up to work, which is not only difficult to apply force, but also The exhaust fan is more likely to fall and hurt others, and lacks the safety of disassembly and assembly. Therefore, the above-mentioned ventilation cover is really necessary to be improved.

In view of this, the inventor of the present invention has been engaged in the manufacturing, development and design of related products for many years. Aiming at the above-mentioned goals, after detailed design and careful evaluation, he finally obtained a practical invention.

The two side plates and the two parallel sides of the upper bracket are assembled and combined, and the two shield portions of the upper cover plate both exceed the upper bracket, and two guide ports and two outlets are formed between the two shield portions and the upper bracket. The diversion space is connected, thereby completing the roof heat dissipation and ventilation cover structure, and exhausting the diversion of indoor air to achieve the effect of heat dissipation and ventilation.

Preferably, two of the combined rod systems are used to install an exhaust fan.

Preferably, the exhaust fan is assembled from top to bottom on the two combined rods of the frame.

Preferably, the two shield portions correspond to the side of the upper bracket provided with the arc-shaped shield, and the two arc-shaped shields extend to the middle section of the diversion space.

Preferably, both the outlets are provided with a net plate.

Preferably, the above-mentioned arc-shaped shield is integrally formed by two parallel top ends of the shield.

Preferably, the arc-shaped shutters are each matched with a mesh plate set at the top of two parallel baffles, and the mesh plates are horizontally shielded at each of the outlets.

Comparing the effects of the prior art: (1) The heat dissipation and ventilation hood frame system restricts the lower bracket to the building room, and uses the inlets around the lower bracket to attract and export indoor air. Based on the principle of hot air rising, it rises to The hot air around the roof will also be guided and sucked in by the inlets, which can reduce the indoor temperature reliably and effectively. In addition, the bottom of the lower bracket is closed with a bottom plate to avoid intuitive attraction and prevent cold air from being led out, increasing The amount of cold air in the room and the time spent in the room greatly enhance the coolness of the room and increase the efficiency of indoor heat dissipation and ventilation.

(2) Furthermore, when the exhaust fan is disassembled and assembled, the disassembly and assembly operations can be carried out from the upper bracket from top to bottom, which makes the replacement or maintenance of the exhaust fan more convenient and convenient, and it can completely prevent the exhaust fan from falling to the ground or It is the risk of hurting others, helps to improve the safety of the structure, and increases consumers' willingness to buy and use.

A bottom plate 121 is provided at the bottom, and a plurality of inlets 122 are formed on the periphery of the lower bracket 12; the outer cover 20 is composed of an upper cover plate 21 and two side plates 22, and the area of the upper cover plate 21 is larger than the The frame body 10 has a horizontal cross-sectional area, and both ends extend downwards with a shield portion 211. The two side plates 22 are connected to both sides of the upper cover plate 21 in parallel, and a shield portion is defined inside the outer cover 20 Diversion space 23. The outer cover 20 has two shield portions 211 corresponding to the sides of the upper bracket 11 provided with the arc shield 112, and extends the two arc shields 112 to the diversion space 23 In the middle section, two side panels 22 and the upper bracket The other two parallel sides of 11 are assembled and combined, whereby both of the upper cover plate 21 and the cover portion 211 exceed the upper support 11, and two guide openings are formed between the two cover portions 211 and the upper support 11 212 communicates with the diversion space 23, and the second diversion outlet 212 is provided with a net plate 213, thereby completing the roof heat dissipation and ventilation cover structure, which is used as a diversion and exhaust of indoor air to achieve the effect of heat dissipation and ventilation.

The arc-shaped shield 112 is formed by integrally forming the top ends of the two parallel baffles 111.

The arc-shaped shutters 112 are each paired with a mesh plate 213 and are arranged at the tops of the two parallel baffle plates 111, and the mesh plates 213 are horizontally shielded at the outlets 212, as shown in FIG.

For the actual installation state of the structure, please refer to Figures 3, 4, and 5. The heat dissipation and ventilation hood is installed on the roof 30 of a building, and the roof of the building is preset with a vent 31. The frame 10 is assembled at the vent 31 from top to bottom, and the lower bracket 12 is restricted to the building room, and the upper bracket 11 is protruding outside the roof, and the upper bracket 11 is outside the block The plate 111 is closely attached to the roof, and it can also be glued and sealed with waterproof tape to avoid rainwater infiltration. The exhaust fan 14 is assembled from top to bottom on the second combined pole 13 of the frame 10, and finally The outer cover 20 is assembled on the upper support 11, and the outer cover 20 faces the opening 113 of the upper support 11 with the diversion space 23, and the two shield portions 211 correspond to the two arc-shaped shields 112, Then the two side plates 22 are combined and fixed with the upper bracket 11, and the inner walls of the two side plates 22 can be provided with a parallel limit frame 221, and the upper frame is straddled through the two limit frames 221.
