JP2019118780A - Automatic laundry rain-proof device - Google Patents

Abstract

To provide an automatic laundry rain-proof device which can be used for two purposes of rain-proof and light-shielding with one device by connecting a motor to a drive shaft of a roll screen.SOLUTION: An automatic laundry rain-proof device uses a screen made of a waterproof and light-shielding material. A drive shaft of a roll screen and a shaft of a motor are connected to each other, and when a detection signal from a rain sensor is received, a motor control device operates, the drive shaft of the roll screen rotates by the motor rotating, the screen is rolled out to a preset position above laundry, and it stops automatically and protects the laundry from rain. In the case of winding up the screen and rolling out the screen for light-shielding, the light-shielding can be adjusted by using a chain of the screen drive shaft. Also, as the device can be mounted on a veranda, a balcony and a window frame, it can widely correspond to the condition of an installation place, and can play two roles of automatic rain-proof and light-shielding with one device.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a laundry automatic rainproof device that automatically rolls out a screen from a roll screen storage unit when rainfall starts and covers the top of the laundry to prevent the laundry being wet from being wet by rain.

In the case of outdoor drying of the laundry on the veranda, there is a device technology (see Patent Document 1 and Patent Document 2) for automatically rainproofing, but all those technologies use the roof of the balcony to receive rainfall from above It is necessary to have existing facilities to prevent.
The invention of the prior art is made for the purpose of rain protection to rain which is blown from an oblique direction.
There is also a technology (see Patent Document 1) that operates only for rain protection.

Utility model registration No. 3008751 Unexamined-Japanese-Patent No. 2017-031602

Therefore, there were the following problems and problems.
(A) Roll screens are devices designed only for shading, and can not be used for rain protection.
(B) Since all prior art rainproofing devices are rainproofing devices assuming only raining from an oblique direction, the installation location of the equipment is limited to a veranda etc. with a roof.
(C) In the prior art, installation costs are also required in addition to the installation because the installation involves special installation work to attach the rainproof device to the outer edge of the roof of the veranda.
The present invention has been made to solve these problems.

The automatic rain-proofing device of the present invention assumes a problem of outdoor drying of laundry on a veranda or balcony, and uses a screen of a material that is both waterproof and opaque to cause sudden rainfall or blowing from an oblique direction. Can prevent the laundry from getting wet.
The present invention processes a part of the roll screen unrolling take-up drive shaft (hereinafter referred to as "drive shaft") and directly connects the motor shaft to the part, thereby detecting the detection signal from the rain sensor installed outdoors. The control device operates, and the rotation of the drive shaft with the rotation of the motor causes the screen to be unwound, and the bottom pipe fixed to the end face of the screen covers the top of the laundry while lowering along the guide string and is preset. It stops automatically at the same position to prevent rain from getting wet from above and from rain from diagonal directions.
When winding up the screen after use, or unrolling the screen for shading, the shading of the screen can be adjusted by using a chain of the drive unit, and one device plays the role of both rain protection and shading. be able to.
In addition, the device according to the present invention can be attached not only to the place where there is a roof of a veranda, but also to a balcony without a roof part or a window frame part of a building.

(A) By changing the screen to a material that is both waterproof and opaque, it can be used for rain protection in addition to the original purpose of rolling screen with one device, resulting in low cost and increased utility value.
(B) The installation of the rainproof device is not limited to the place with the roof, but it can be installed anywhere as long as the lightweight roll screen can be fixed.
(C) The installation cost can be reduced because special installation work is not required for fixing the rainproof device.

  It is explanatory drawing which showed the state which unwound the screen of this invention.   It is a perspective view of the roll screen main body and drive part of this invention.

Hereinafter, embodiments of the present invention will be described.
When rainfall starts, a detection signal (not shown) from a rain sensor (5) installed outdoors is transmitted to the motor control device (6), and the motor (4) rotates.
A drive shaft (11) directly joined to a pulley (10) attached to the motor shaft (9) rotates in synchronization with the motor (4).
By rotation of the drive shaft (11), the screen (2) wound around the drive shaft (11) is unwound, and the bottom pipe (3) attached to the end face of the screen unwinding and also serving as a weight is along the guide cord (8). Cover the upper part of the laundry while falling down, and automatically stop at a preset position by the timer (not shown) of the motor control unit (6), and the laundry is rained from above and blown down from an oblique direction Prevent getting wet.
Guide cords (8) are stretched one by one from the both ends of the frame (1) to the veranda handrails (7), serving both as a vertical movement guide of the bottom pipe (3) and preventing the screen (2) from flying off by wind. Play a role.
A waterproof cover (14) covers the entire motor (4) to prevent waterproofing in order to prevent failure of the electrical system due to rainfall or the like.
The present invention is configured as described above.
When using the present invention, first attach the frame (1) to the outer edge of the roof, roof or window frame of the veranda, and then attach the bottom pipe (12) to the hanging hooks (12) attached to both ends of the bottom pipe (3). Pass the guide cords (8) of 3), and draw one guide cord (8) between each end of the frame (1) and the veranda handrail (7).
The rain sensor (5) is fixed at an appropriate place outside where rain can be directly detected, and is connected to the motor control device (6) by wiring.
The motor control unit (6) is connected to the motor (4) by wiring, placed in a place where it can be protected from rain or indoors, etc. to turn off the power, and turn it on when it is used.
If it starts to rain slightly, the motor control device (6) works by the detection signal from the rain sensor (5), and the screen (2) is unwound along the guide cord (8) by the rotation of the motor (4) Cover the top of the and stop at a preset position to prevent the laundry from getting wet due to rainfall.
When taking in the laundry, turn off the motor control unit (6) and use the chain (13) to wind up the screen (2).
When using for the purpose of shading, turn off the motor control device (6) and adjust the unwinding width of the screen (2) using the chain (13).
Remove the guide cord (8) from the veranda hand rub (7) and wind up the screen (2) with the chain (13) if strong wind is expected or it will not be used for rain protection because it is installed outdoors .
