Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> This invention relates to a ventilation system operated by sunlight.

<Prior Art and Its Problems> Much research has been conducted to ventilate automobiles by installing ventilation devices operated by sunlight (ie, solar cell ventilation devices).

These studies involved placing solar panels in the roof of a car to run a fan, which is a part of a normal car air conditioner. The solar panel and ventilation fan needed to be electrically and/or mechanically connected to the car, requiring modifications to the car and thus also reducing the safety of the car. Ventilation in other locations (eg rooms or buildings) was also investigated by installing solar ventilators.

These ventilators require installation of the ventilator in a barrier (e.g., wall or roof) outside the installation site or modification by drilling holes to provide the necessary airflow.

Means for Solving the Problems According to the present invention, a solar cell ventilation device has been proposed that can be attached to the edge of a movable window of a car, that is, a window that can move upwards and downwards.The installation is simple. It can be used without impairing the normal opening and closing operation of the window, and generally on either edge (e.g. on the movable edge of a barrier), regardless of whether the edge belongs to the window side or the car side. It is suggested that it can be installed.

The ventilation system does not require any external electrical connection work, and no modification or other installation work is required to install the ventilation system in a car or other location.

<Operation> A first feature of the invention is that support means for supporting the ventilator from the edge so as to be adjacent to a first region on a first side of the edge, at least one inlet and at least one outlet;
at least one inlet for admitting air from the first region; at least one outlet for discharging air into the second region; at least one outlet for inlet air (or vice versa); a housing with an inlet and at least one outlet), a fan integrated in the housing that allows air to be taken in and removed, and a solar generator that drives the fan depending on the irradiation of the sun's rays; This relates to ventilation equipment installed in

A second feature of the invention defines an edge provided with at least one solar ventilator according to the first feature of the invention. The invention may be embodied in any suitable manner depending on the nature of the edges.

An example of an edge is the edge of a barrier, i.e. a movable window in a motor vehicle or building.

Preferably, the solar ventilator is a one-piece device.

The support means may be extendable laterally depending on the dimensions of the window or other barrier. The support means may have a specially designed end shape and a telescoping member. The support means may comprise first and second extensions adjustably extendable from first and second sides thereof, such as, for example, opposite ends of the top of the window. at least one part of the support means comprises, for example, an overhanging part that acts as the point of engagement;
It may be constituted by a housing optionally with at least one fitting or mounting on the edge.

At least a portion of the support means may fit into at least one optional mating portion of the frame or other portion proximate to the barrier (and the housing itself may constitute the support portion; the housing may at least one protrusion corresponding to an optional recess in at least one of a frame or the like, such as an architectural window frame or an automobile window frame, the at least one protrusion being received by the at least one recess; Preferably, the fan is integrated into the housing. Examples of the fan include a rotating fan or a vertical fan. The solar generator includes at least one photovoltaic generator, i.e.
It consists of one photovoltaic cell or photovoltaic element mounted on the inside or outside of a plate (ie photovoltaic cell array plate) or window.

Generally, photovoltaic generators are mounted and arranged so that they can receive sunlight directly and/or indirectly. In the case of direct light reception, at least one photovoltaic generator is located externally, i.e. adjacent to the area of the external surface of the window, at a location such as adjacent to the window part and/or to the external part of the support means, e.g. It is placed in a place where it can be combined with the overhanging part of the

<Example> The present invention will be described below based on the accompanying drawings showing specific examples thereof.

In FIGS. 1 and 2, the solar ventilator 1 is a downwardly/upwardly movable edge 2 of a window 3, or whether the barrier is a window or belongs to a motor vehicle or another vehicle. It is a one-piece device that fits onto the edge of any other suitable barrier regardless.

The ventilation device 1 comprises a housing 4 with an overhang 5 that fits into the edge 2. The housing 4 has an upward channel 6 that fits into a recess 7 in an adjacent frame, e.g. a car frame.
It is equipped with The first and second lateral extensions 8.9 are telescoped into the respective side edges of the channel 6 to ensure safety in any window size. In order to prevent the extension 8.9 from being pushed back into the interior of the channel 6, a fixing rod 10 is provided in the middle of the extension 8.9 inside the channel 6. The housing 4 is provided with a plurality of air circulation holes 11, for example in the case of an automobile. The housing 4 has a vertically elongated exhaust port 1 leading to the outside of the car.
