Abstract

To provide an automatic rainproof device for laundry capable of automatically preventing laundry from getting wet by rainfall and being used for two purposes of sunshade and rainproof by mounting a canvas switch automatic device in an awning originally used as a sunshade.SOLUTION: In an automatic rainproof device for laundry, a canvas switch automatic device can be easily detached with only a butterfly nut without requiring mounting construction and a tool and has a structure in which a canvas can be opened/closed on both sides of a canvas roll. When rainfall starts, a detection signal from a rain sensor is transmitted to a motor control circuit of the automatic device, a canvas switch automatic handle mounted on one side of the canvas roll is rotated and the canvas is automatically drawn, and an upper part of laundry is covered and laundry is prevented from getting wet by rainfall. When the canvas is stored and is used as a sunshade, the canvas can be opened/closed using a canvas switch manual handle mounted on the other side.SELECTED DRAWING: Figure 1

Description

The present invention relates to a laundry automatic rainproof device that automatically pulls out a canvas from a canvas roll when rainfall starts and prevents wet laundry from being wet due to rain.

There is a device technology (see Patent Document 1 and Patent Document 2) for automatically rainproofing against rain that laundry that has dried on a veranda etc. blows obliquely, but all of these techniques Installation work of the rainproof device is necessary. There is also a technology (see Patent Document 1) that operates only during rainfall.

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

In the case of drying laundry on a balcony or veranda or the like, it has been a problem that the dry laundry gets wet due to rainfall or blowing down because the weather suddenly changes while going out. The present invention solves the problem of outdoor drying and has been made as having a structure that can be used as a sunshade.

The automatic rainproofing device of the present invention does not require installation work and tools, and can easily attach the automatic rainproofing device to the canvas roll attachment leg, and by attaching canvas switches on both sides of the canvas roll, The canvas has a structure that can serve two purposes: rain protection and awning. A canvas switch automatic device attached to one of the two canvas roll attachment legs is activated by the detection signal from the rain sensor, and the canvas is automatically pulled out from the canvas roll for rain protection. When the canvas is stored or opened as a sunshade, the canvas can be opened and closed by the canvas handle manually attached to the other side. The structure of the canvas switchgear automatic device is connected to the motor by the rotation of the motor of the automatic device, the detection signal from the rain sensor which detects the rainfall installed outdoors when the rainfall starts is sent to the motor control circuit of the automatic device By rotating the bolt and rotating the canvas switch automatic handle connected with the bolt, the canvas is pulled out of the canvas roll and automatically stops at the set position covering the top of the laundry, and the laundry by rainfall Prevent getting wet.

When the laundry is dried outdoors, it is possible to prevent the laundry from getting wet from rainfall caused by sudden change in the weather, and to go out with peace of mind while keeping the laundry dry. In addition, the present invention can be used as a sunshade while preventing the laundry from getting wet due to rainfall with a single canvas, and it can serve two purposes at low cost, increasing its utility value.

Hereinafter, embodiments of the present invention will be described.
(A) When rainfall starts, a detection signal (not shown) from the rain sensor (14) installed outdoors is transmitted to the motor control circuit (FIG. 3), and the cross section of the drive unit of the present invention is "「 " The motor (12) attached to the V-shaped metal rod (13) rotates. Rotation of the bolt (9) joined to the rotation shaft of the motor (12) rotates the canvas switch automatic handle (5) joined to the bolt (9), and the canvas roll (2) ) Is pulled out and covers the top of the laundry to prevent the laundry from getting wet due to rainfall. Also, the pulled out canvas (1) automatically stops at the position set by the timer of the motor control circuit (Fig. 3).
(B) In order to prevent breakdown of the automatic system electrical system due to rainfall etc., the entire automatic system section (6) is covered with the waterproof cover (6) of the appliance and waterproofing measures are taken. However, to ensure the safety of the automatic device (6) from strong winds and lightning strikes, the automatic device (6) is fixed to the canvas roll mounting leg (3) with a U-shaped bolt and a wing nut for complete safety. The bolt-handle joint (8) of the automatic unit (6) is also joined with a wing nut, so that the automatic unit (6) can be easily attached and detached without the need for installation work and tools.

When using the present invention, the automatic device portion (6) is fixed to the canvas roll mounting leg (3), and the bolt-handle joint (8) of the automatic device portion (6) is fixed with a wing nut. Next, a rain sensor (14) wired to the motor control circuit box (15) is fixed at an appropriate place outdoors where rain can be directly detected. The motor control circuit box (15) makes an electrical circuit connection with the automatic device unit (6) with a connector, places it in a place where it can be protected from rain or indoors, and turns off the power, and turns it on when used. If it starts to rain slightly, the motor control circuit (Fig. 3) is activated by the detection signal from the rain sensor (14), the canvas (1) is pulled out from the canvas roll (2), and the laundry is covered Prevent getting wet. Also, the pulled out canvas (1) automatically stops at the set position by the function of the timer of the motor control circuit (FIG. 3). After taking in the laundry, use the canvas handle manual handle (7) and store it on the canvas roll (2). When using for the purpose of sun protection, adjust the opening and closing of the canvas (1) according to the strength of the sun using the canvas switch manual handle (7).

Claims (1)

In the automatic rain protection system, the canvas switch automatic device works by the control signal of the motor control circuit that receives the detection signal from the rain sensor due to rainfall, and the canvas is automatically pulled out from the canvas roll to cover the upper part of the laundry. The automatic rain-proof device for laundry that is characterized by using a handlebar for canvas opening when storing the canvas after use or opening and closing it as a sunshade by preventing the laundry from getting wet by standing still.
