Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a component for attaching a small fan for forcedly ventilating indoor air to a small ventilation window at the top of a door where the sash is misplaced.

[0002]

[Prior art]

 Traditionally, most ventilation fans are used in kitchens, toilets, and washrooms, and are rarely used for ventilation in living rooms. So-called ventilation fans for windows are also sold, but they are not widely used because they are limited to large-scale ventilation fans, and there are problems with opening and closing of windows and door locks, and problems with the interior. Absent. Even if you want to use the ventilation fan for ventilation in the living room, there is no easy way to install it, except when there is a dedicated mounting hole at the time of construction. It is possible to construct a new mounting hole after construction in a wooden house, but it is almost impossible to construct a new mounting hole in a concrete house where ventilation is highly required.

[0003]

[Problems to be solved by the device]

 In concrete houses such as highly airtight condominiums, measures against moisture are a major concern for residents. Especially during the winter, water generated indoors has no place to escape, so it will condense on glass windows, walls, and other places with low temperatures. This tendency is particularly noticeable in the north room, which causes stains on the walls and causes mold and ticks. Futons should be damp, and tatami mats and carpets should be closed. Of course, even in the rainy season, there is no end to the worries of moisture. In public housing, etc., a small glass door for natural ventilation may be attached to the upper part of the sash window, but the opening is small and it is hardly useful. Hygroscopic agents such as calcium chloride are also commercially available, but their effects are not sufficient.

[0004]

[Means for Solving the Problems]

 Forced ventilation is a powerful means to solve this problem, but in many cases other than kitchens and bathrooms, ventilation fan mounting holes have not been prepared in advance, which has become a major concern for people living in concrete houses. Unlike kitchens, bathrooms, and toilets, general living rooms and sleeping rooms do not generate much water, so it is sufficient to use a very small ventilation fan to force ventilation. Simply installing a small ventilation fan with a blade diameter of 8 cm to 12 cm and power consumption of 5 W to 15 W is surprisingly effective. The problem is where to install. Except for the case where there is a mounting hole for ventilation fans at the time of construction, new construction is not possible in concrete houses such as apartments, so there is no target place other than windows. The inventor focused on a small window for natural ventilation above the sash window, which is often found in public housing, and studied the method of easily installing a small ventilation fan on this small window, resulting in the present invention. It is a thing.

[0005]

[Action]

 The present invention relates to a component for easily attaching a small fan for forcedly ventilating indoor air to a small window for ventilation at the top of a sash. Most of the small windows for natural ventilation above the sash windows, which are often found in public housing, have a distance between the upper and lower sills of the small window of about 12 cm. Therefore, a suitable ventilation fan is a so-called household fan. The most suitable is not a commercially available ventilation fan, but a small and thin fan with a blade diameter of about 10 cm, which is widely used for cooling computers, printers, and other electronic devices. This fan consumes less power, has a lower noise level and is surprisingly cheap. Since the thickness of the fan is extremely thin, around 25 mm to 38 mm, it does not interfere with the opening and closing of the windows and internal shoji, and there are no problems in terms of crime prevention or interior decoration. Attach this fan to the square or near square support plate with screws. At this time, it is better to insert a rubber packing for vibration isolation between the support plate and the fan. When installing on a small window, first open the glass door of the small window by the width of the support plate, then insert the support plate between the upper and lower sill and fix it.

The fitting of the present invention is characterized in that half of the thickness of both the upper and lower sides of a rectangular support plate, which is close to a square, is cut so that it fits into the sill of the small ventilation window. This allows the fan to be installed without using any tools, just as if the door were fitted into the sill.

[0007]

【Example】

 An embodiment of the present invention shown in the accompanying drawings will be described. As shown in the figure, the present invention comprises a square or rectangular-shaped rectangular support plate having a side of about 14 cm and a thickness of about 10 mm, and has a hole having a diameter of about 8 to 12 cm through which a wind passes. Drill four screw holes around the hole to attach the fan. Cut one half of the thickness of both the upper and lower sides of the support plate into the sill of the small ventilation window. The depth of the cut depends on the depth of the sill, but is generally about 8 to 12 mm for both the upper side and the lower side. FIG. 1 b. And d. The space between them is the most important, and if this is not smaller than the space between the upper and lower thresholds, the support plate cannot be fitted. Instead of cutting the upper and lower sides of the support plate, prepare two 5 mm thick plates, one of which is 16 to 24 mm shorter in the vertical direction than the other in the vertical direction and approximately the same size in the horizontal direction, and glued so that the center lines overlap. Wind holes may be formed at the top and center, and screw holes may be formed at the four corners. A small and thin fan is attached to this support plate with a screw, and it is fitted into the sill of a small window for ventilation just as if the door was to be fitted into the sill.

[0008]

[Effect of device]

 The present invention has the following effects by being configured as described above. In other words, there is no conventional method for easily installing a commercially available ventilation fan in a concrete house such as a mansion, except when a dedicated ventilation fan mounting hole is provided, and residents suffer from moisture, condensation, and mold. It was However, according to the present invention, as long as there is a small window for ventilation on the upper part of the sash sliding door, anyone can install a small fan easily and at very little cost, so that a comfortable living space is immediately available. Can be created, and the effect obtained is extremely large.
