Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to a drying rack for drying laundry, etc., and in particular, by being rotationally driven by the electromotive force of a solar cell.
This relates to a clothes drying rack that quickly dries clothes using uniform sunlight conditions and wind generated by rotational motion. [Prior art and problems to be solved by the invention] Conventionally,
The most common types of clothes drying racks are the stationary type with a ball on a stand, the hanging type that hangs from the ceiling, and the wall-mounted type that is attached to the balcony railing. Some have a rotatable structure for convenient attachment and removal of laundry. No matter which drying rack is used, the laundry is dried by the heat of sunlight or by the action of wind. Also, in case of rainy or cloudy weather, warm air dryers that use electricity or gas as an energy source have become popular for home use in recent years.
Due to the complicated structure, the machine is expensive and has not been widely used, and the electricity and gas costs are high.
Many households use a drying rack. Under these circumstances, there is a need for an inexpensive and quick-drying means for drying laundry and the like that does not require electricity or gas costs. [Object of the Invention] The object of the present invention is to dry laundry at low cost and quickly by effectively utilizing natural wind and sunlight without using commercial power sources, dry batteries, gas, or other costly energy. It's about getting the means. [Means and operations for solving the problems] As a means for achieving the above-mentioned object, the present invention includes a rotatable clothes drying rack body, a rotating means for performing the rotation, and a solar cell. The present invention provides a multi-rotation clothes drying rack with a solar battery, characterized in that the clothes drying rack main body is rotationally driven by supplying electromotive force of the solar battery to the rotating means. According to the present invention, laundry can be efficiently dried and uniformly sterilized by sunlight by automatically rotating the laundry and using the generated wind without any human intervention. Moreover, it is possible to realize a clothes drying rack with a simple structure and low maintenance costs. In addition, once the rotation drive itself starts rotating by -degrees, it can maintain rotation with a small amount of driving force due to inertia, so even on cloudy days, it can be easily rotated by a combination of a small motor and a small solar cell. can be carried out.

【Example】

Hereinafter, the present invention will be explained in more detail based on drawings and various embodiments. (Example 1) FIG. 1 is a drawing that best represents the features of the present invention,
The rotational drive is not only based on the electromotive force of the solar cells, but also uses the electromotive force of the solar cells to use the force that causes the drying rack itself to start rotating due to a slight wind as a starting force and maintain rotation in the direction of rotation. It is configured to transmit the driving force of the supplied motor. In the figure, 1 is a hook for hanging the clothes drying rack, 2 is a solar battery, 3 is a motor with gears, 4 is the clothes drying rack itself, and 5 is a hook for urging rotation by the wind when natural wind is blowing. It is an impeller. Fig. 2 is an example of the electric circuit of the embodiment shown in Fig. 1, in which 2 is a solar cell, 3 is a motor with gears, and 6 is a motor when the clothes drying rack main body 4 is rotated forward by the wind. Zener diode 7 prevents the generated electromotive force from being too strong and destroys the solar cells, and conversely protects the motor when the electromotive force of the solar cells becomes excessive for the motor. This diode prevents the electromotive force generated by the motor from destroying the solar cells when the motor rotates in reverse. With the above-described configuration, when the solar cell 2 is exposed to sufficient sunlight on a clear day and the generated power is supplied to the motor 3, the geared motor 3 drives the clothes drying rack main body 2 through a reduction gear (not shown). , generates a driving force for rotation in the direction of the arrow in FIG. This driving force rotates the drying rack main body 2, thereby making it possible to expose the laundry to sunlight uniformly and to accelerate drying by the airflow caused by the rotation. When equipped with a motor that can rotate in either direction, if it is rotated by the wind or by hand, the electromotive force generated by the motor will be applied to the solar cells in the forward and reverse directions, causing deterioration or damage to the solar cells. There is a risk that it will be destroyed. The diode 6.7 is provided to prevent this. Under the scorching sun, the electromotive force of the solar cell becomes too large, and as a result of supplying excessive power to the motor 3, the diode 6 A Zener diode is used to prevent the wire from burning out. With this configuration, it looks no different from a conventional clothes drying rack, and can be rotated automatically without the use of human hands or commercial power, allowing for efficient drying and sunlight disinfection. Even if a large number of laundry items are attached to a hanging clothes drying rack, all the weight is applied to the hook l, and the force required for rotation is extremely small, so a sufficient rotation speed can be obtained even with a very low output motor. In addition, as for the motor, it is preferable to use a motor that can be driven with a minute current and is as small as possible.
pm) with various reduction gearboxes. In addition, since these devices are used outdoors, suitable exterior materials include corrosion-resistant metals such as stainless steel and brass, resins such as polyethylene, polypropylene, and vinyl chloride, and motors and gearboxes encapsulated in glass. Possible solar cells include gallium arsenide solar cells, crystalline selenium solar cells, monocrystalline silicon solar cells, polycrystalline silicon solar cells, and amorphous silicon solar cells, but they are expensive due to their use on a drying rack. Amorphous silicon solar cells are the most preferable because they are unacceptable and do not require a particularly large output power as mentioned above.
An amorphous silicon solar cell manufactured by CS Co., Ltd. and rated at 16V was used. As for the material of the main body of the drying rack, one of the factors is that it is light, so resin such as ABS resin, polyamide, etc.
Preferred are polyamideimide, polypropylene, polystyrene, polyvinyl chloride, and the like, and in this example, polypropylene was used. As mentioned above, if there is large frictional resistance in the rotation drive part, the drive torque will increase in response to the load of the hanging laundry, and the rotation speed of the drying rack body will decrease. A ball bearing, a roller bearing, a sliding member made of a low frictional resistance resin such as a fluororesin, or a sliding member made of an oil-impregnated metal such as oil metal is used for the joint portion. Here, ball bearings were used. (Comparative Example 1) As Comparative Example 1, the drying rack of Example 1 was manufactured in which the connection wire from the solar cell to the motor was cut to prevent rotational driving force from being transmitted. Four wet towels were attached to both Example 1 and Comparative Example 1, and a laundry drying experiment was conducted on a cloudy day with almost no wind. Since there was almost no wind, the drying rack of Comparative Example 1 did not rotate at all, and the towels in the shade did not dry even after 5 hours. On the other hand, the drying rack of Example 1 started rotating slowly (about 15 r, p, m) even after the laundry was attached, and all the laundry was dried in the drain for 3 hours. (Embodiment 2) Fig. 3 is a diagram showing a second embodiment, in which human power or external starting force such as wind is used to start the rotation, and the motor is controlled to maintain rotation in the rotation direction. A switch configured to supply the electromotive force of the solar cell is provided so that the starting rotation direction can be arbitrarily determined. In the figure, l is a hook for hanging the clothes drying rack, 2 is a solar battery, 3 is a motor with gears, 4 is the clothes drying rack itself, 8 is a drive supply polarity switch, and there is a slight friction between the upper and lower units. A resistance is provided, and when the lower part begins to rotate due to human power, wind, etc., the rotation direction switch is closed and lightly locked. FIG. 4 shows an electric circuit of the embodiment shown in FIG. 3, where 2 is a solar cell, 3 is a motor, and 6 is an electromotive force generated by the motor when the laundry rack main body 4 is rotated in the wind. Zener diode 7 protects the motor from being too strong and destroying the solar cells, and conversely protects the motor when the electromotive force of the solar cells becomes too strong for the motor. A diode 8 is used to prevent the electromotive force generated by the motor from destroying the solar cells when the motor rotates, and 8 is a drive supply polarity changeover switch that uses wind power. With the above-described configuration, the clothes drying rack main body 4 generates a driving force to rotate in the arrow direction a shown in FIG. 3, using an external force such as wind as a driving force. This driving force causes the lower unit of the drive supply polarity changeover switch 8 to rotate, for example, in the a direction, and the electromotive force of the solar cell 2 is supplied to the motor 3 with a polarity that maintains rotation in the a direction. As a result, the drying rack that had been stopped starts rotating and continues to rotate. With this configuration of this embodiment, there are no restrictions on wind direction or installation location, making it even easier to use. Also, if the wind is strong, the drying rack itself may rotate too quickly. In the configuration of this embodiment, which allows rotation in either direction, the electromotive force generated by the motor is applied to the solar cells in both forward and reverse directions, so a diode is installed to prevent the solar cells from deteriorating or being destroyed. 6.7 shall be provided. As for the diode 6, a Zener diode is used to prevent the electromotive force of the solar cell from becoming too large under the scorching sun, supplying excessive power to the motor 3, and thereby preventing the motor 3 from being burnt out. With this configuration, it does not look any different from a conventional clothes drying rack, and it can rotate automatically and perform efficient drying and sunlight disinfection without worrying about wind direction or using human hands or commercial power. It becomes possible. With a hanging clothes drying rack, even when many laundry items are attached, all the weight is applied to hook 1, and the force required for rotation is extremely small, so a sufficient rotation speed can be obtained even with a very low output motor. . (Comparative Example 2) As Comparative Example 2, a clothes drying rack of Example 2 was manufactured in which the connection wire from the solar cell to the motor was cut to prevent rotational driving force from being transmitted. Four wet towels were attached to both Example 2 and Comparative Example 2, and a laundry drying experiment was conducted on a sunny winter day with a wind force of 2. Because the wind was blowing a little, the clothes drying rack of Comparative Example 2 rotated occasionally, but it took 4 hours for all the towels to dry. On the other hand, the clothes drying rack of Example 2 has laundry attached thereto and continuously rotates while occasionally changing the direction of rotation depending on the direction of the wind and efficiently utilizing the natural wind.
It took a while for everything to dry. (Example 3) FIG. 5 is a diagram showing a third example, in which the electromotive force of a solar cell is used for the rotational driving force, and when the electromotive force of the solar cell is supplied to the motor, the turning on, A switch is provided to turn off the laundry by detecting the weight of the laundry, and an LED is provided that lights up when the laundry is dry and light, so that the time of completion of drying can be determined by the LED. In the figure, 1 is a hook for hanging the clothes drying rack, 2 is a solar battery, 3 is a motor with gears, 4 is the clothes drying rack itself, 9 is a switch that switches the power supply according to the load, and the upper unit 9a and the lower unit 9b A spring (
(not shown), and when heavy wet laundry is hung, the switch 9 is turned on, supplies power to the motor 3, and starts rotating.
When it dries and becomes lighter, the return force of the spring turns off the switch 9, stopping rotation, and the LED II lights up. 10 is a spring strength adjustment screw. FIG. 6 is an electric circuit of the embodiment shown in FIG. 5, where 2 is a solar cell, 3 is a motor, and 6 is an electromotive force generated by the motor when the clothes drying rack main body 4 is rotated by the wind. The Zener diode 7 prevents the solar cells from being destroyed due to too strong electromotive force, and conversely protects the motor when the electromotive force of the solar cells becomes excessive for the motor. Diode that prevents the electromotive force generated by the motor from destroying the solar cells when the motor rotates in reverse, 9
is a switch that changes the power supply depending on the weight of the laundry. With the above-described configuration, when the clothes drying rack main body 4 is hung with wet and heavy laundry, a spring (not shown) stretches, and in FIG. 5, 9b extends in the direction of the arrow relative to 9a, turning on the switch. This generates rotational driving force. This driving force makes it possible to automatically rotate the device for efficient drying and sunlight disinfection without using human hands or commercial power. When the laundry gets dry and becomes lighter, the spring contracts and 9b becomes narrower in the direction of arrow B with respect to 9a in Figure 5, the switch is turned off and rotation stops, and the LED II indicates that drying is complete. lights up. This operation allows you to check from inside the room that the laundry is dry. (Embodiment 4) Figure 7 is a drawing showing the fourth embodiment, which is a stationary type that is used not only for drying laundry but also for drying insects on clothes and as a display for clothes etc. in front of a store. It belongs to In the figure, 1 is a support ball that supports a clothes drying rack;

The electric circuit is exactly the same as in the second embodiment. Although the embodiments of the present invention have been described above, the present invention is not limited to the above-mentioned embodiments, and a structure in which the solar cells are placed at a remote location and connected with electric wires can also be adopted. Further, the same effect can be obtained by using a buzzer or the like instead of the LED. [Effect of the Invention J According to the present invention, as a power source for rotating the clothes drying rack,
