Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a ridge ventilation system, and more specifically, to a ridge ventilation system installed on the roof of a house.
This invention relates to an improvement of a ridge ventilation system that is provided with a passage and an exhaust port that communicate with a ventilation opening provided in the roof, and that ventilates the attic area through the ventilation opening, passage, and exhaust opening.

[Conventional technology]

Generally, the roof of a house has a closed structure using a heat insulating material, with emphasis on rain protection and heat retention/insulation in winter.

[The problem that the idea aims to solve]

Therefore, when a room is heated, the warmed air rises and brings moisture into the attic. If this is left untreated, condensation water will not only corrode wood and damage insulation, but also seep onto ceilings and walls, causing damage to household goods.

Therefore, as a means to solve the above problem, a ridge ventilation system is used to ventilate the roof. This ridge ventilation system removes moisture from the attic through a natural ventilation flow that takes advantage of the temperature difference between indoors and outdoors. A good ventilation effect can be obtained. In other words, the forced ventilation system shown in Fig. 6 is a ventilation tower c that is installed at the top of a house a to communicate between an attic b and the outdoors, and a ventilation fan d consisting of a motor and a fan is installed within this ventilation tower c. Also,
It had a structure in which a solar cell f was installed on a part of the roof e, and this solar cell f was connected to a storage battery g, and was also connected to the ventilation fan d via an inverter h and a control section i. (See Publication No. 59-60138).

[The problem that the idea aims to solve]

However, with this kind of structure, the equipment is large-scale and not only expensive, but also difficult to install in an existing house.

[Means to solve the problem]

Here, this invention provides a ridge ventilation body attached to the roof of a house with a passage and an exhaust port that communicate with a ventilation hole provided in the roof, and these ventilation holes,
In a ridge ventilation system that ventilates the attic through passages and exhaust ports, on the top surface of the top plate of the ridge ventilation body, which is composed of a member that is substantially continuous in the longitudinal direction,
A pair of parallel guide grooves are formed that are continuous in the longitudinal direction, and a solar cell is inserted between these guide grooves, and a pair of concave grooves that are continuous in the longitudinal direction are formed in the inner wall of the ridge ventilation body. The present invention proposes a ridge ventilation system in which an electric fan having a shape elongated in the longitudinal direction of the ridge ventilation body is inserted between these grooves.

[Effect]

That is, in this invention, a solar cell is inserted into a guide groove formed on the top plate of the ridge ventilation body, and an electric fan driven by this solar cell is inserted between the grooves formed on the inner wall of the ridge ventilation body. This system automatically controls the amount of ventilation during the day and at night, by performing forced ventilation using solar cells as a driving source during sunshine and by natural convection at night.

(not shown), and an inner wall that extends in a bent direction from the upper end of this seating part 6 in a direction approaching each other, and between them constitutes the ventilation opening 5 and a passage 2 communicating therewith. 7, a side plate part 8 located outside the inner wall part 7 with a gap, and a top plate part 9 that covers the upper surfaces of the inner wall part 7 and the side plate part 8, and the top plate part 9 Solar cells 11, 11... are fitted into a pair of mutually parallel guide grooves 10, 10 provided on the top side, and a part of the top plate portion 9 is constituted by these solar cells 11, 11... ing. Further, on the upper vertical piece 7a of the inner wall portion 7 and on the outer side of the top plate portion 9, a plurality of press-hole-shaped exhaust ports 12, 12...; 12',
12'... are arranged in a row at appropriate intervals. Note that 13 is a water drain port provided between the inner wall portion 7 and the lower end side of the side plate portion 8, and 14 is a water drain port provided to prevent a short circuit between the exhaust port 12 of the inner wall portion 7 and the exhaust port 12' of the top plate portion 9. These water drain openings 13 and blocking pieces 14 allow for good rain protection.

On the other hand, as shown in FIG. 2, the electric fan 3 has a fan cover 18 that includes a horizontal mounting member 16 having a ventilation hole 15 in the center thereof, and a cover portion 17 extending in a curved manner below the mounting member 16. It has a unit structure in which the motor 19 and the motor 19 are integrally attached therein, and grooves 20, 20 forming a pair formed in opposing parts of the upper vertical pieces 7a, 7a of the inner wall parts 7, 7 are provided.
