Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a vent device for passing air from one of the vents to the other.

[0002]

[Prior art]

 Ventilation is provided to exchange indoor dirty air with outside air. Conventional ventilation openings consist of openings and lodges to prevent the invasion of animals, etc. is there. The ventilation openings are basically based on natural ventilation. However, in some places, the desired ventilation effect may not be obtained, and it is costly and time-consuming to adopt forced ventilation completely.

[0003]

[Problems to be solved by the invention]

 The present invention has been made in view of the above points, and an object of the present invention is to provide a ventilating device with a fan which has a forced ventilation function as well as natural ventilation.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a fan in a forced air vent that is attached to a vent, installs a solar cell that converts light energy into electric energy in the main body so that it can catch light easily, and a motor that drives the fan. And a means to electrically connect the solar cell.

[0005]

[Embodiment of the invention]

 The ventilating device of the present invention is for allowing air to pass from one side of the vent to the other side, thereby providing ventilation. The air vent here is provided for the purpose of natural ventilation, and a forced air vent for forced ventilation is also provided. A fan is provided in the forced ventilation port.

A solar cell that converts light energy into electric energy is installed in the main body of the ventilating device as a power source for driving the fan. Solar cells can be said to be functional devices that directly convert the light energy of sunlight into electrical energy, but they can also generate power using not only sunlight but also other light sources.

The solar cell is installed on the main body so as to easily catch light throughout the year, but the most efficient method is to incline the solar cell so as to face the sun. In such a case, it is desirable to install the solar cell at an angle that is orthogonal to (ie, directly opposite to) the sunbeams in the middle of summer and winter, that is, southern as the equinox or autumn equinox.

[0008] The solar cell may be provided with a battery support on a main body and installed on the main body. As the battery support, a lower frame plate (or an upper frame plate may be extended) of the frame plates constituting the main body can be extended. Since the lower frame plate or the upper frame plate and the battery support have a structure in which the outside is inclined downward, they also have a function of receiving and flowing down rainwater.

[0009]

【Example】

 The present invention will be described in more detail with reference to examples. The illustrated ventilating device with fan 10 has a frame-shaped main body 11 in which a rectangular venting hole 12 is formed as viewed from the front, and a plurality of armor plates 13 are provided between the left and right frame plates. It is designed to maintain ventilation and block rainwater intrusion. The lower frame plate 14 of the main body 11 is inclined outward and downward, and an eave-shaped portion extending outward is used for the battery support 15. See FIG.

[0010] The forced ventilation port 16 is provided alongside a part of the main body ventilation port 12, and has a configuration in which forced ventilation covers a part of natural ventilation. An electric fan 17 is provided in the forced vent 16, and the fan 17 is electrically connected to the solar cell 20. Reference numeral 18 denotes the code, and reference numeral 19 denotes a switch. The switch 19 can be set to be used, for example, for switching the wind direction or as an on / off switch for the fan 17.

The solar cell 20 is installed on the battery support 15 in the direction of the sun. Strictly following the condition of facing the sun at the vernal equinox, the rising angle A of the battery support 15 is the same 36 degrees when the latitude of Tokyo is 36 degrees. However, the difference in electromotive force due to the difference of several degrees is small, and in the case of the mid-latitude region, the angle should be between 30 degrees and 40 degrees.

When the device 10 of the present invention having such a configuration is installed in the opening 21 of the installation portion, it is suitable for rain and allows rainwater to flow in to the outside. See FIG. In the case of illustration, the solar cell 20 receives the solar radiation, drives the fan 17, takes out the inside air, and has a function of taking in the outside air from another ventilation port (or a function of taking in the outside). If the solar radiation is weak, the starting power is small and the forced ventilation function is stopped at night, but the natural ventilation function is left, so the ventilation performance as a whole is greatly improved.

[0013]

[Effect of the invention]

 Since the present invention is constructed and operates as described above, it is possible to drive the fan with light energy to forcibly ventilate and simultaneously ventilate by natural ventilation, thereby significantly improving the ventilation performance. Since it operates automatically, there is no need for labor, and there is no need for wiring and electricity, and it is easy to use.
