JPH02271899A - Clothes-drying platform with solar battery - Google Patents

Abstract

PURPOSE:To automatically move a clothes-drying platform between the outdoor and a part under the eaves according to the weather and to efficiently execute drying or disinfection by sunning the laundry or the like by utilizing driving force, which is fluctuated according to the light reception quantity of a solar battery, as motive power source for moving the stand of the clothes-drying platform or the clothes-drying platform itself. CONSTITUTION:When a solar battery 2 is irradiated with enough solar light at the time of fine weather and power to be generated by the solar battery 2 is supplied to a motor 3, the motor 3 is rotated and a torque limiter 6 is driven through a reduction gear. This torque limiter 6 drives a clothes-drying pole holder 1 in an arrow B direction and a clothes-drying pole, to which the laundry or the like is hung, loaded on the clothes-drying pole holder 1 is moved to an outdoor side. On the other hand, when the intensity of the solar light is decreased, the generated power of the solar battery 2 is lowered and the elastic force of a spring 5 is larger than the force of the motor 3 for feeding out the clothes-drying pole. Then, the clothes-drying pole holder 1 is pulled back in an arrow A direction. At such a time, since the power to be generated by the inverse rotation of the motor 3 goes to be forward bias to the solar battery 2, there is danger that the solar battery 2 is degraded. A diode is provided to prevent this degradation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a clothes drying rack that uses solar energy to move between under the eaves and outdoors.

[Prior Art] Conventionally, common types of drying racks include a stationary type with a ball on a stand, a hanging type suspended from the ceiling, and a wall-mounted type attached to a balcony railing. Currently, there are very few things that can be moved. Therefore, when the weather is nice, people dry their laundry on drying racks in sunny places, and when it rains or in the evening, they move it under the eaves or other roofs.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional example, there is a drawback that if a person leaves the laundry outside and goes out, the laundry gets wet due to sudden rain. However, if you leave it until night, it will become damp or wet with night dew.Also, if you leave it under the eaves or other roof all the time, it will not be able to dry sufficiently or be disinfected by sunlight.

These drawbacks can be solved by a device that automatically moves between under the eaves and outdoors, which has a moving device powered by a light sensor, humidity sensor, etc., and a commercial power supply or dry cell battery. The problem is that it becomes complicated and increases electricity costs.

Therefore, an object of the present invention is to automatically move between outdoors and under the eaves depending on the outside weather without any human intervention.
To realize a clothes drying rack which can efficiently dry laundry etc., disinfect by sunlight, etc., has a simple structure, and does not require maintenance costs.

[Means for Solving the Problems] As a means for solving the above-mentioned problems, the present invention provides a clothes drying rack that includes: a movable clothes drying rack or the clothes drying rack itself; a moving means for moving the clothes drying rack; The present invention provides a clothes drying rack with a solar cell, characterized in that it has a solar cell, and uses electromotive force that varies depending on the amount of light received by the solar cell as a power source for the movement.

[Function] A movable drying rack or rack with moving means,
? It becomes possible to move Ic laundry etc. between outdoors and under the eaves. Furthermore, by directly inputting power from the solar cells that varies depending on the amount of light received into the moving means, it becomes possible to automatically carry out moving operations according to the weather. That is, when the weather is good, the sunlight is strong and the amount of power generated by the solar cells increases, and when it is rainy or when dry weather is not suitable, such as at night, the sunlight becomes weak and the amount of power generated by the solar cells is reduced.

Therefore, if you move according to this change in power generation,
It becomes possible to automatically move laundry etc. efficiently.

[Example] (Example 1) Figure 1 is a drawing that best represents the features of the present invention, and in the figure, 1 is the amount of clothesline, 2 is a solar cell, 3 is a motor with a gear, 4 is a stopper that stops clothesline 1 from moving too much, 5 is a spring that pulls back clothesline 1 when the power of motor 3 is off, and 6 is a spring that prevents clothesline 1 from moving too much. A torque limiter 17, which operates so that the motor 3 rotates idly when the clothesline is running, is a gear for supporting the clothesline 1, and 8 is a support for supporting the entire clothesline holder 1.

FIG. 2 is an electrical circuit diagram of the embodiment shown in FIG.
3 is a solar cell, 3 is a motor, 201 is a diode for preventing the electromotive force generated during reverse rotation of the motor from being applied as a forward bias to the solar cell, and 204 is a switch.

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 motor 3 rotates and is transmitted to the torque limiter 6 via a reduction gear (not shown). to drive. This torque limiter
Reference numeral 6 drives the clothesline 1 in the direction of arrow B, and moves the clothesline with laundry (not shown) placed on the clothesline 1 to the outdoor side.

The details of this torque limiter 6 are not shown, but it is composed of two coaxial gears, and a torque greater than the elastic force of the spring 5 is transmitted by a known means interposed between one gear and the shaft. When the stopper 4 comes into contact with a stop member (not shown) and the clothesline rod amount 1 stops, it acts to rotate idly. Therefore, as long as the solar cell 2 is generating sufficient power, the motor 3 will rotate and the clothesline 1 will always be kept extended in the direction B. On the other hand, when the intensity of sunlight decreases, the power generated by the solar cell 2 decreases, and the elastic force of the spring 5 becomes greater than the force of the motor 3 that sends out the clothesline, and the clothesline 1 moves in the direction A. be drawn back to.

At this time, since the electric power generated by the reverse rotation of the motor 3 becomes a jIt bias for the solar cell 2, there is a possibility that the solar cell 2 will deteriorate. Diode 201 is provided to prevent this.

Normally, a pair of clothesline 1 is installed with the side in the direction of arrow 6 in Figure 1 facing under the eaves and the direction of arrow B facing outdoors, and the clothesline is hung with laundry etc. to make it 1. When the switch 204 is turned on and the solar cell 2 is not exposed to sufficient light, the spring 5 stores the clothesline 1 under the eaves (in the direction A). When the solar cell 2 is exposed to sufficient light, the electric motor 3 operates to send out the clothesline 1 outdoors (in the direction B), and the clothesline 1 is stopped at a predetermined position by the action of the dork limiter. Also, if sufficient light does not hit the solar cell 2 (when the spring 5 causes the clothesline 1 to be retracted under the eaves (in six directions). It will be possible to move it so that it can be dried, disinfected by sunlight, etc.

Further, if the switch 204 is turned off, the clothesline 1 can be taken under the eaves at any time by the action of the spring 5.

When we prototyped the above clothesline and conducted an experiment on a sunny day during the winter solstice when the sun's altitude was low, we found that the clothesline was outside from around 100 a.m. to around 2 p.m. By this time, they were under the eaves, allowing sufficient drying and sunlight disinfection without getting damp from the night dew.

(Example 2) Fig. 3 is a diagram showing a second embodiment, in which the clothesline rods shown in Figs. 1 and 2, which were separated into a pair of left and right in Embodiment 1, are integrated. This is a view from above.

In the figure, 301 is the amount of clothesline, 302 is the solar battery, and 3
04 is a stopper, 308 is a support, and the motor 3, spring 5, torque knob 6, etc. shown in FIG. 1 are also provided, although not shown, and the electric circuit shown in FIG. 2 was also used.

When we prototyped the above clothesline and conducted an experiment similar to Example 1, we found that the clothesline was carried outdoors from around 8 a.m. to around 4 p.m., and at other times. The solar cells were stored under the eaves, and as in Example 1, they did not get wet with night dew (and were able to be sufficiently dried and disinfected by sunlight automatically. In Example 2, the solar cells 302 that is larger than that in the first embodiment, the generated power is also large, making it suitable for moving a heavy clothesline.

Further, the present invention is not limited to the above-described embodiments, and a structure in which the solar cells are placed at a separate location and connected by electric wires can be adopted, and the same effect can be obtained.

Furthermore, it is possible to obtain the effect that maintenance costs such as electricity charges are not required.
