JP2000304319A - Ventilation fan for ventilation opening - Google Patents

Abstract

PROBLEM TO BE SOLVED: To utilize effectively a ventilation opening and thereby to ensure ventilation of a room, by fitting a ventilation fan by providing a frame having such a shape as to cover an opening part frame of the ventilation opening intended for natural ventilation. SOLUTION: In order to provide a ventilation fan 1 for a ventilation opening formed for natural ventilation and provided with a glass pane 5 which can be opened and closed, a frame having such a shape as to cover a frame 4 forming an opening part of a ventilation opening is provided. Then, a ventilation fan 1 wherein a motor fan 2 having propeller-shaped vanes is incorporated is so fitted as to cover that frame, by using fitting means, e.g. a plurality of Velcro fasteners 3A and 3B. By driving this ventilation fan 1, polluted air containing cigarette smoke in a living room where smoking is made, for instance, can be exhausted rapidly and the effect of ventilation is increased.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Industrial applications] Usually, small ventilation windows are glass sliding doors with ventilation small windows that are frequently used on the terrace side of collective housing in the form of buildings. Two horizontal rectangular glass plates are drawn above the inner sliding door. As a difference, it is a small window incorporated with the same structure as a glass shoji.

[0002]

2. Description of the Related Art Usually, small ventilation windows are intended for natural ventilation. However, due to a difference in temperature between the inside and outside, when the outside air flows in or the temperature inside and outside is equal, the small window for ventilation is usually used. Its ventilation capacity is questionable. In particular, it is hopeless for rapid outdoor ventilation of smoking.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a ventilation fan for forced ventilation at the opening of a small ventilation window for natural ventilation. Conventionally,
This ventilation small window is provided for the purpose of natural ventilation,
The effect is questionable depending on conditions such as the temperature difference between indoor and outdoor. In particular, the smoking caused by smoking is quicker,
As for ventilation, it is hopeless. The present inventor is also a smoker who lives in a house using this small ventilation window, but is a member of the fireflies who glow on the terrace in the evening, smoking and smoking on the terrace at night because of the care of the family, It denies the ventilation capacity of small windows.

[0004]

SUMMARY OF THE INVENTION The present invention is provided with a frame having a shape such that a frame of a ventilation fan corresponding to the inside dimensions of the frame forming the opening portion covers the frame of the opening portion frame. To install the opening frame and the frame of the ventilation fan, use multiple Velcro on the opening frame without using parts such as bolts, screws, screws, etc. And realized by the method of attaching.

[0005] With this mounting method, the function of the ventilation small window to form the target opening can be impaired, but can be avoided, and when the ventilation fan is removed, it can be performed without leaving a trace on the frame of the opening.

FIG. 1 is a perspective view of a frame constituting an opening portion of a small ventilation window and a ventilation fan for a small ventilation window of the present invention mounted so as to cover the frame. Reference numeral 2 denotes a motor fan having a prolera type blade found in a normal ventilation fan.

FIG. 2 is a perspective view of a ventilation fan for a small ventilation window using a cylindrical fan motor used in a room air conditioner or the like in the frame of the ventilation fan of the present invention.

[0008] In addition, there is a blower fan or the like having a shape that strongly sucks in air and sends it out as wind. The main subject of the present invention is a frame for mounting a ventilation fan that matches a size inside the opening and a method of mounting the same. Therefore, the description of the electric and mechanical systems is omitted.

[0009]

As described above, the ventilation fan for a small ventilation window according to the present invention has been realized as a result of finding an opening for natural ventilation as an installation port of the ventilation fan. As a result, in our living room, where smoking was prohibited in the past, smoke was promptly discharged, and smoking was recognized by the family, and the effect was enormous. In addition, this ventilation fan
It is very useful if you devise the ventilation of the closet, cupboard, storage room, etc.

[Correction contents]

As described above, by using the attaching method of attaching, it is easy to remove the ventilation fan when cleaning it. In particular, in the case of a rental house, there is no processing damage due to the removal of the ventilation fan, so this is an ideal method that does not contribute to the cause of trouble when canceling the rental.

Claims (2)
