By the way, in the case of buildings such as public housing and private rental housing, for example, the period between the move of the resident and the next person, the period after the construction, or the long-term absence, etc. Depending on the circumstances, the vacancy may continue.
In addition, villas and warehouses that are not normally used are also vacant.

  The dwelling where the person does not live is quickly hurt. Therefore, it is difficult to manage the house until it is delivered and maintained without being uncomfortable. For example, when a curtain or the like is not used, the tatami mat and the inner wall are burnt by sunlight and become discolored and dirty. Therefore, the light is usually shielded by a curtain made of black paper or the like.

However, when a curtain or the like is used, discoloration such as tatami due to sunlight can be prevented. However, since the room is closed, the air cannot be circulated with the outside air, and the room air stagnates. In recent years, buildings are particularly airtight, and in summer, etc., the outside air temperature is high, so the room temperature rises remarkably, and there is no escape from the raised air. As a result, there is a problem that mold adheres to the inner wall or the like due to moisture or the wallpaper is damaged.
There is a built-in ventilation fan in the kitchen and bathroom of the building, but it cannot be used because electricity is not available in the vacant room.

  In order to solve this problem, for example, a person in charge of the management company regularly checks and opens all windows and puts air into the room. For example, if there is only one vacancy, the difficulty of management will be somewhat reduced, but it will not be possible to omit the trouble of ventilating, etc. Management is difficult, and as a result, labor costs are bulky and burdensome.

  In the vacant room, as soon as the next occupant moves in, daily life begins and the built-in ventilation fan operates, so the room is also ventilated at all times. Therefore, a ventilator with a structure that can be removed quickly and easily once the ventilator is released is temporarily attached and a ventilator that provides sufficient ventilation effect is temporarily installed before it is released. If there is, the above problem can be solved. In addition, a configuration that can be attached using the attached part of the building without crafting the building for attachment is preferable. For this purpose, a ventilation fan that is small and has a simple structure and can be easily carried is desirable.

However, the ventilating fan 100 of Patent Document 1 is for indoor ventilation and uses a solar panel. However, the ventilating fan 100 has a complicated structure and cannot be easily attached or detached. Can not.

It has been. Therefore, it is impossible to remove the coaxial pipe 101 and the like from the wall 110 because the wall 110 must be broken. Solar panels are installed outdoors.

Therefore, if the ventilation fan 100 of Patent Document 1 is used for ventilation for a short period of time in a building such as a public housing as described above, it must be newly constructed for installation or removed. In such a case, it is necessary to fill the part and return it to the original state. Thus, since attachment and removal are difficult, there arises a problem that much labor, time and labor are required.
Therefore, it is conceivable to install the ventilation fan 100 from the beginning when constructing a building such as a public housing. However, there is a problem of the site and the like, for example, it is difficult to install a solar panel.

Hereinafter, embodiments of a ventilation fan with a solar panel (hereinafter simply referred to as a ventilation fan) according to the present invention will be described with reference to the drawings.
1 to 6 show a first embodiment of the ventilation fan 1. FIG. 1 is a basic system diagram of the ventilation fan 1. FIG. 2 is an overall schematic diagram of the ventilation fan 1. FIG. FIG. 4 is a longitudinal sectional view taken along line IV-IV in FIG. 3, FIG. 5 is a perspective view of the ventilation fan 1, and FIG. 6 is a perspective view of the outside air intake fan 30. .

First, the basic system of the ventilation fan 1 will be described with reference to FIG.
The ventilation fan 1 includes a power generation unit 10 that supplies electric power generated by taking in sunlight, and a ventilation fan main body unit 20 that performs ventilation using the electric power supplied from the power generation unit 10.

  The power generation unit 10 includes a solar panel 11 that takes in sunlight to generate power, a capacitor 12 that stores electricity generated by the solar panel 11, a circuit 15 that connects the power generation unit 10 and the ventilation fan main body 20, and this circuit. 15 is provided with a resistor 13 provided in 15 and a switch and a light detection sensor (not shown).

  The ventilation fan main body 20 holds a motor 21 that is rotated by the power generation of the solar panel 11, a fan 22 that is rotated by the rotation of the motor 21, the motor 21 and the fan 22, and the first of the building. The sliding door sash 50 (see FIGS. 2, 5, and 6), which is an attachment site, includes a frame body 23 that is detachably mounted.

The size of the solar panel 11 is, for example, a vertical dimension of 180 to 190 mm, a horizontal dimension of 250 to 260 mm, a thickness dimension of 15 to 20 mm, and a planar size of B4 size, which is a paper standard. It is formed in almost the same size.
The output of the solar panel 11 is set to be 4.5 W at MAX, the current is 250 mA at MAX, and the current is 18 V at MAX. However, during normal use, that is, in actual use, it is operated at 70 to 75% of the above numerical values when viewed from experimental data, and a sufficient effect can be obtained in this state.

A small DC fan motor 21 is used as the motor 21, and the size thereof is, for example, 80 mm × 80 mm × thickness 25.5 mm. The maximum air volume is 0.73m ³ /min~1.2m ³ / min, the driving voltage is 8.4～13.8V (DC), the drive current has become 80 mA.

The size of the fan 22 is formed to have a diameter that is substantially the same as a height dimension of a small window portion 53 (see FIG. 5) described later, for example, 100 to 120 mm. The fan 22 has a current of 160 mA, a rotation of 2150 min, and a power of 1 W.
The battery 12 is, for example, a lithium ion battery that can be charged and discharged, and a battery with a DC of 12 V and a capacity of 1000 mAh to 1600 mAh is used.

  As described above, when the current of the solar panel 11 is 250 mA at MAX, the capacitor 12 is 170 mA, and the drive current of the motor 21 is 80 mA, the power of the motor 21 generated by the solar panel 11 (at the time of fine weather) is 18V, 250 mA. The battery 12 is charged while driving 80 mA. When this is expressed by a mathematical formula, it can be understood that 250-80 = 170 mA, and the charging current is 170 mA.

  In addition, when calculating how long it takes to fully charge when using the capacitor 12 having a capacity of 1000 mAh, it becomes 1000 ÷ 170≈5.9, and it can be fully charged in 5.9 hours within the sunshine hours. It is.

  When solar power generation stops, such as in the shade during charging, the ventilation fan 1 is driven by the already charged battery 12. In this case, 1000 ÷ 80 = 12.5, and only the battery 12 operates for 12.5 hours.

  From the above, the daily power generation operation time of the solar panel 11 is calculated. For example, when the sunshine time in which the most efficient power generation can be expected in the solar panel 11 is 9 hours from 7:00 to 16:00, it can be operated for about 20 hours by adding the above 12.5 hours to the 9 hours. . Although this operation time does not reach the full operation for 24 hours, the operation for about 20 hours has a sufficient effect as the capacity of the small and light ventilation fan 1 as described above.

Next, the structure of the ventilation fan 1 will be described with reference to FIG.
The ventilation fan 1 includes the power generation unit 10 and the ventilation fan main body 20.
The power generation unit 10 includes the solar panel 11 that takes in sunlight to generate power, and a capacitor 12 that is integrally provided on the back surface of the solar panel 11 and stores electricity generated by the solar panel 11. ing.

Further, a panel support 17 is provided on, for example, the upper surface of the solar panel 11.
The panel support 17 supports the solar panel 11 at a predetermined position where the sunlight hits. The panel support 17 is a string-like member having one end fixed to the upper surface of the solar panel 11 and the other free. , And a hook member 19 provided at the tip of the chain 18.

The length of the chain 18 is adjustable, and the hook member 19 is formed, for example, in a bowl shape. As a result, when the solar panel 11 is arranged at a predetermined position where the sunlight H hits, the hook-shaped hook member 19 is hooked on the second attachment site (specifically, a curtain rail 57 described later), and the chain 18 Thus, the solar panel 11 can be arranged in a suspended state.
A rope or the like may be used instead of the string 18 as the string-like member, and the hook member 19 may not be hook-shaped and may be, for example, a clothespin shape that can be fixed at the position.

The ventilation fan main body 20 includes a frame body 23 that is detachably attached to a sliding door sash 50 that is a first attached site of a building.
The frame body 23 has a main body portion 23A inserted into a small window portion 53 (see also FIGS. 5 and 6) provided on the upper part of the sliding door sash 50 of the building, and a motor support for supporting the motor 21 and the fan 22. The unit 23B is provided with a hood 23C that prevents wind and rain from entering the room of the building.

As shown in detail in FIG. 3, the main body portion 23 </ b> A is formed of a rectangular plate, and an opening 23 </ b> D for discharging air sent from the fan 22 is formed in a substantially central portion thereof. The opening 23D is rectangular.
Both end portions in the short side direction of the main body portion 23A are window frame insertion portions 23E along the long side direction with a predetermined width dimension. The window frame insertion portion 23E is used when the frame body 23 is attached to an upper small window portion 53 of a sliding door sash 50 installed in a public house, for example, as an attachment site of a building. It can be inserted into the groove 55A.
In addition, an insect screen 24 for preventing insects from entering the room from the outside is stretched in the opening 23D.

  The motor support portion 23B is provided on the indoor side surface of the main body portion 23A. The motor support 23B is formed in a shape that keeps the fan 22 at an appropriate distance from the opening 23D and does not hinder the rotation of the fan 22. In order to reduce the weight, for example, four plate-like members formed with a predetermined width are arranged in a hooked shape, for example, as shown in FIG. Yes.

  The hood 23C is for preventing rain, snow, strong winds and the like from blowing into the room through the opening 23D, and is formed to protrude to the front side of the main body 23A, that is, the outdoor side. The hood 23C has a projected area that is large enough to cover the opening 23D, and has a side cross-section that has a gentle arc shape and projects forward. The hood 23 </ b> C can be inserted through the opening space when the glass small window 54 of the upper small window portion 53 is opened.

The above description is the description of the ventilation fan 1 that discharges indoor air to the outside, but FIG. 4 shows the outside air intake fan 30 that takes outside air into the room.
The outside air intake fan 30 can ventilate the room air only with the ventilation fan 1, such as when the vacant state extends for a long period of time, and particularly when the temperature of the room rises markedly when the temperature in summer increases. Since the room temperature cannot be lowered, the outside air is inhaled and ventilated, so that the room temperature is lowered.

  As shown in FIG. 4, the outside air suction fan 30 includes a frame main body 31 formed of a rectangular plate and a hood 32 provided on the outdoor surface of the frame main body 31. A rectangular opening 31A is formed at a substantially central portion of the frame body 31, and an insect screen 33 is stretched on the opening 31A. Further, both ends in the short side direction of the frame body 31 are window frame insertion portions 31E along the long side direction with a predetermined width dimension. The window frame insertion portion 31E can be inserted into the groove 55A of the small window frame portion 55 when the frame main body 31 is attached to the upper small window portion 53 of the sliding door sash 50.

As can be seen from FIGS. 3 and 4, the outside air intake fan 30 has substantially the same shape as the shape in which the hood 23 </ b> C is provided on the main body 23 </ b> A of the frame body 23 of the ventilation fan 1.
The outside air suction fan 30 as described above is also easily attached to the small window portion 53 of the sliding door sash 50B different from the sliding door sash 50A (see FIG. 5), similarly to the frame 23 of the ventilation fan 1. It comes to be detachable.

  Next, based on FIGS. 5 and 6, a state in which the ventilation fan 1 and the outside air suction fan 30 as described above are attached to a sliding door sash 50 in a public housing, for example, will be described.

First, the room R in the building will be described.
In the room R of the building, for example, two sliding door sashes 50 are provided as slidable left and right as boundaries with the outside. The sliding door sash 50 includes a frame member 51 formed of aluminum or the like with a predetermined standard dimension, and a window glass 52 fitted into the frame member 51.
Further, a small window portion 53 formed in a frame shape is provided on the upper portion of the sliding door sash 50, and a slide opening / closing type glass small window 54 is fitted in the small window portion 53. The glass small window 54 is inserted into the groove 55A of the small window frame section 55 in the small window section 53, and can slide within the groove section 55A.
Furthermore, a curtain rail 57 that is a second attached site of the building is laid on the wall portion 56 of the building above the sliding door sash 50.

The ventilation fan 1 is attached across the small window portion 53 of one sliding door sash 50A and the curtain rail 57 among the two sliding door sashes 50 shown in FIG.
That is, the glass small window 54 of the small window part 53 is opened, and the insertion part 23E of the frame body 23 of the ventilation fan 1 is inserted into the open space, and one of the upper and lower sides is inserted into the groove part 55A first, and the other The frame body 23 is attached by inserting the opposite side into the groove portion 55A on the opposite side while adjusting the position. At this time, the hood 23C is located on the outdoor side.
The attachment of the frame body 23 is performed by the above-described operation in a room with the hood 23C inserted through the open space where the glass small window 54 is opened with the frame body 23 held in both hands.

On the other hand, the said solar panel 11 is arrange | positioned facing the glass 52 in which the electric power generation side takes in sunlight. That is, the solar panel 11 is provided in a state where the hook member 19 at the tip is hooked on the curtain rail 57 and then suspended from the chain 18, and the length of the chain 18 is set so that the solar panel 11 is in the optimum position. For example, it is opposed to the glass 54 on the upper part of the frame member 51.
Although the solar panel 11 is suspended from the chain 18, it has a predetermined weight because the battery 12 is also provided integrally, and the air in the vacant room has a flow of air for ventilation. Since it is only there, the solar panel 11 will not be in an unstable state.

Further, for example, the outside air suction fan 30 is attached to the sliding door sash 50B of the adjacent room R with respect to the single sliding door sash 50A to which the ventilation fan 1 is attached.
That is, the outside air intake fan 30 is provided in an open space in which the glass small window 54 of the small window portion 53 of the sliding door sash 50B is opened. The room R with the sliding door sash 50A to which the ventilation fan main body 20 including the motor 21 and the like is attached and the room R with the sliding door sash 50B to which the outside air suction fan 30 is attached are for good indoor ventilation of the building. In addition, it is better to leave the doors open.

When the outside air suction fan 30 is attached, the procedure is substantially the same as the attachment of the frame body 23 described above.
Therefore, outside air is sucked into the room R from the outside air suction fan 30 and is discharged outside by the ventilation fan 1 in a state where the outside air and room air are mixed. The ventilation fan 1 is driven by electricity from the solar panel 11 that generates power from sunlight H incident from the window glass 52.

According to the ventilation fan 1 of 1st Embodiment as mentioned above, the following effects are acquired.
(1) The ventilation fan 1 is configured to include a power generation unit 10 and a ventilation fan body 20, and the power generation unit 10 includes a solar panel 11 and a capacitor 12, and the ventilation fan body 20 includes a motor 21, a fan 22, and these Since the motor 21 and the frame 23 that holds the fan 22 are configured, the structure is simple, and the air chamber can be automatically ventilated while being easily portable.

  (2) The ventilation fan main body 20 is attached to the sliding door sash 50, which is the first attached part of the building, through the frame body 23, and the power generator 10 is connected to the curtain rail, which is the second attached part of the building, by the chain 18. The ventilation fan 1 can be attached by being supported by 57. The removal can also be performed in the reverse procedure, and after the removal, it can be used in another place. By using this, the curtain rail 57 can be easily attached and detached, and can be reused.

  (3) By inserting the insertion portion 23 </ b> E of the frame body 23 into the groove 55 </ b> A of the small window frame portion 55 of the sliding door sash 50, the ventilation fan main body portion 20 can be attached to the small window portion 53. As a result, since it is installed using the existing one, it is not necessary to perform a new construction or the like to install the ventilation fan 1, and it is not necessary to repair after the removal. In particular, in buildings such as public housings, the standard of the sliding door sash 50 is standardized, and the size of the small window part 53 is also uniform, so one type of ventilation fan main body 20 and eventually the ventilation fan 1 is prepared. Since it is sufficient, production and management are easy.

  (4) Since the hood 23 provided integrally with the frame body 23 is formed in such a size that the small window portion 53 can be inserted, the ventilation fan main body portion 20 can be attached from the indoor side.
