CONSTITUTION:A wiper intermittent driver B of a wiper motor 20 is fitted with a frosting prevention time relay 12 adapted to conduct current from a battery 16 at an interval to the extent free from exerting adverse effect on the start up of the engine by discharge of the battery 16, a frosting prevention switch 13 adapted to conduct current to the time relay 12 from the battery and a outside air temperature sensor 22 for actuating the relay 12 when the temperature of air outside a car lowers below a specified value. With such an arrangement, only if the switch 13 is closed before-hand, the time relay 12 is actuated with the sensor 22 to drive the motor 20 intermittently at said interval when the temperature of outside air lowers below a specified value.

Description

[Detailed Description of the Invention] The present invention is to prevent frost from forming on the windshield when parking at night, etc., and to prevent it from freezing and hindering visibility when starting to drive. There is *M, 411 in a cold region, when 1 is outside at night, 4 falls on car 111, it freezes due to the drop in temperature, and the outside surface of the windshield Kd [Kid] is formed.
Sticking may occur. In this case, even if you try to start driving, you will not be able to drive because the outer surface of the window is frozen and the visibility is being used. Therefore, this frozen layer must be removed, or a direct connection layer can be used to do so. 4. This requires extremely troublesome and time-consuming work, such as preparing plkdIk for solving the problem.

As a conventional A1 that prevents this 4 attachment, the actual N5j-7
As disclosed in Japanese Patent No. 050, when necessary, as shown in Figure 7, an adhesive anti-freeze 11) such as 4 is applied to the front window uO [covering and fixing].

When there is a risk of food being loaded, this is done by forming a planar body on the front pillar (9) of the vehicle as shown in Figure 7. ) are fixed with screws through the ball holes +311ml in both layers, and the main body (attached to the inside of the case - 11) is
The main body (pulled out from the wound, this 4 etc.) Ft-4 anti-tilting d 111 is a layered layer on the outer surface of the front windscreen, and it is fixed to the 4 of 4 + 11. Place the attached front pillar (4) on the other front pillar +91i
There are so many things that make me stop.

However, this conventional muzzleloader had several drawbacks.

First, KV′i using the conventional key 11 (g) written as
At the time of starting the Red Army and when starting the run, pull out the 1g +11 from inside the main body (2) of the -fold, and rewind the jItI/-h and insert it into the main body (inside the main body). Is it necessary to store it in
A11) If there is 4J Sugi no Hoku d+1 on the top, it must be rewound and stored in the main body of the #L removed, that is, a troublesome operation to use it. is necessary.

In addition, this conventional equipment d≠) has been changed to one front pillar (
9) Once it is fixed with screws, it will remain unattached during the winter due to mold from use. For this reason, outside of iL@
And the driver's field of vision is greatly affected.

Furthermore, since this conventional installation 7) is used as a Vc outside the vehicle, someone else may not be able to install it while the vehicle is parked. You can easily remove +C4 by loosening the screw 131.

Therefore, there was a risk of theft.

Therefore, the present invention takes account of the above-mentioned conventional drawbacks, and will be explained in detail below.

Book) A Ming is a shiver (mult) as shown in Figure 7, which is installed on the front window etc. for the purpose of wiping off rain and dirt.
) is used, and when the temperature of the company's middle and outer part drops, the window VC does not stick, and the MD of the battery discharges or the engine starts. ．． Set Jl14 and drive intermittently to prevent the formation of freezing 1- of 4 in the area wiped by the wiper, so that the visibility necessary for driving at the start of single-wheel drive is lost. That's what I did.

In order to achieve the above object of the present invention, a configuration for giving the wiper a number of nights is, for example, a conventional wiper intermittent supply system as shown in FIG. When the battery is discharged to the engine, the 4-inch prevention time relay (121) and the 4-inch prevention time relay (121) that causes the exhaust from the battery to evaporate, and the battery to the prevention time relay with the upper DID ( A seeding prevention switch V that makes the flow 14, and a foreign temperature sensor 1j2t that disturbs the above 1 prevention time relay 112+ when the external air 1 becomes low F immediately after a predetermined value are installed. In addition, ill
To increase the robustness, it is possible to set a humidity level on the glass surface and attach it to the outer fifji sensor 4 and the AND condition. α41 fuse, tlil is a backflow prevention diode. .

In addition, the conventional wiper access roller shown in Figure 2)
(Same as those with the same reference numerals in Figure 3)
u61 is the battery installed in iL, *711d ignition switch, ustIi fuse, μmari is the wiper switch, Ako is the wiper motor that helps the wiper, d
is a conventional control circuit that supplies current to the wiper motor IA from the battery U-.

Next, the operation of A1 shown in FIG. 3, which is one of the J columns of the present invention, will be explained.

Conventional wiper production dJA, 〆(B
), the wiper 1 of the 4th generation, which is a 4th generation wire, has the ignition switch dη connected to the ignition position d (It)), and turns on the wiper switch theory, and the conventional city U-circuit 12υ This is done by supplying current from the battery U. The conventional city U control circuit 1l causes the wiper motor to apply a drive current 1 to a predetermined brush to assist the wiper.

In addition, #IJ prevents frosting, which is a feature of the present invention.
To explain the operation, this is done by turning on the 4-inch prevention switch t14 when there is a risk of a 4-inch collision, such as when parking. Since this 4th station is parked, the ignition switch I and wiper switch tlii
Is 1 OF? Since the vertical position is 1/1, the time relay with 4 is supplied with current from the battery II-, so the JIL outside air I is blown out by the outside temperature sensor 12i5. At 9 o'clock, tIJt started after falling below the predetermined 1st shift (for example, Ko OC), and Aki, who was in the middle of the peak, was on the wind. The windshield wiper motor is energized from the battery l181 at intervals that do not affect the temperature.In addition, in order to accommodate one-time tilting, an extra Vc voltage sensor Tcl!31 is installed to sense the outside temperature. Jun and Ando 4k17F- were connected 4 times, at intervals of 4 degrees so that the food of the 4 guns did not stick to the windshield, and when the battery was discharged.
It may be possible to energize the wiper motor at intervals of Vhi degrees without causing any adverse effects on the first pongee. Make it go back and forth to wipe out the wind.

Here, we will explain the specific flow of the wiper motor that satisfies the above conditions to prevent seeding and discharge the battery.

If you let the wiper motor run for 2 seconds, let the wiper move once at a rate of VclI, and if this continues for m hours, the battery will discharge (it is about 93kkK). This is also the same as −j
At kV+, when the wiper is used for 70 minutes, the discharge of the battery is approximately o, /Jd.
On the other hand, the photoelectric capacity of nine batteries installed in a small car is
In general, the JON da is 0■, and if the approximately 50 width is charged, the engine starting aid is Roe Tiger. Therefore, if the windshield wiper is operated properly within the range of 2 to 70 minutes mentioned above, the battery number range will be 1 without affecting engine start #K, -4 and 4. can be prevented.

The anti-frost device of the present invention is particularly needed in 47
In the cold climate headquarters, the battery is exposed to 50*1 light of the same type, so the radiation by VC (congratulations to the characteristics, 7& is danced almost entirely from the outside.

Also, when there is a strong wind at Makei Pond, the phenomenon marked with ■ above occurs @
Since VC is more likely to occur, several layers of antifreeze can be sprayed onto the window 1 at the same time as the 4-position IJJ to prevent seeding according to the present invention, as an auxiliary feature of the device of the present invention. In this case, install an antifreeze washer (not shown) separately.
As shown in FIG. 7, the washer motor is connected so that it is supported by the IE time relay force. In addition, in Figure 65, the same reference numerals as those in the Kagu diagram indicate the same book. As a result, the washer motor ring is assembled in conjunction with the 4VC wiper motor, which prevents damage from occurring, and antifreeze can be applied to the outside surface of the window.

As explained above, according to the present invention, it is possible to
When the vehicle is parked outside, the windshield wiper wiper 4d can be prevented from turning 4d by simply turning on the anti-frost switch. Therefore, you can enjoy the visibility necessary for driving by 4 degrees and drive quickly by 19 degrees. 1. Also, by setting the time interval for intermittent operation of the windshield wiper so that the resulting battery discharge does not cause the engine to start @VC-t4, and by providing an outside temperature sensor, the outside temperature of the vehicle can reach the predetermined temperature plate F. mFt, because the wiper VC 4-inch preventive operation is performed only occasionally, there is no need to increase the charging capacity of the battery or install a separate power station!
In addition, if antifreeze can be sprayed onto the windshield in synchronization with the wiper maintenance prevention L) + aid 1, an even better trend prevention effect can be obtained.
Even when the 14 is downwind and the 9 is the 9, it will be a great success if you use it on the F.
