The washer fluid instantaneous water heater 10 is a conventional washer fluid pump. Attached in the middle using a hose between the nozzle and the nozzle, the automatic start and defroster control device 30 is integrally integrated, and is operated by a clock and an operation button switch installed on the operation panel 20.

FIG. 5 is a block diagram of an apparatus for automatically starting and defrosting the present invention. As shown therein, a power supply unit 100 for supplying power to a system and a 24-hour clock T _{24 are} provided at a predetermined time (10). Startup signal unit 200 operated for a minute), a startup start unit 300 for repeating the start three times for a predetermined time (15 seconds), and a startup completion operation for detecting the startup completion operation of the startup start unit 300 completion detecting section 400, and the heating unit 500, the generator power detection relay (X _G) for the start-up completion detecting section 400 is excited to be heating after confirming completion of start-up, (on the temperature detection relay (THR) on ) And a washer fluid pump operating part 600 for pumping the washer fluid, and a wiper operation part 700 for discharging the washer fluid by the washer fluid pump operating part 600 and operating the wiper after 1 second. Referring to Figure 6 in detail as follows.

After connecting washer liquid pump outlet and washer liquid nozzle hose at both ends of washer liquid instantaneous water heater 10, and connecting heating element terminal to control device 30, the clock is connected to the control device 30 in the clock operation panel. Setting at time excites a 24-hour clock [T ₂₄ (On for 10 minutes at the setting point) a contact On cell motor starting relay (X ₁ ) at the set time. The generator power detection relay (X _G ) indicates the condition without starting, indicates the defrosting main relay (X ₂ ) heater stop state, and powers on the starting time relay [T _S (15 sec On)]. The supplied time limiting relay (T _S ) a contact is turned on for a time (15 seconds) that the starting operation can be repeated up to three times.

On the other hand, the power is supplied to the cell motor start-up flicker relay device (T / FR Unit) by the cell motor starting relay (X ₁ ) a contact, so that the cell-motor start-up flicker relay (T / FR) a contact point When on (on time: 1 second), the side brake must be braked (S _LS acontact on), and the transmission parking (P) or neutral (N) positioning switch S ₉₉ (AUTO) or manual transmission When the N position check switch S _PT (photoelectric switch) is in a normal state, the cell motor (SM) is started and started.In this case, if the first start fails, the motor starts again after 4 seconds (starting again twice). When the engine is started (800 rpm), the generator power detection relay (X _G ) is excited (generator voltage generation) to stop the cell motor (SM).

In addition, when the cell motor starting frieker relay T / FR is first excited, the cell motor SM is driven and power required for driving the engine (fuel pump power and spark plug power) is a starting auxiliary relay (X _S). Excitation and supply power to 15 wires, in which the starter auxiliary relay (X _S ) is self-maintained as a contact and the starter auxiliary relay (X _K ) is a relay operated by a car key.

In addition, since 15a is a power source for generating generator power and an accessory power supply such as an air conditioner of a vehicle, a security device is secured by a contactor for cell motor starter relay (T / FR) so that the battery does not become excessive during startup. When the b contact point of the start time relay (T _S ) is completed after completion, the heater start time relay [T _H (contact point of off characteristic after 1 second on)] is excited and the defrosting operation is performed by turning on the instantaneous water heater heater power. In this case, the cell motor starting relay (X ₁ ) must be demagnetized and defrost completion timer (T ₁ ) must also be decomposed, and when the washer fluid shortage detection switch (WS) is normal (washer fluid sufficient), the defrost main relay ( X ₂ ) is excited and defrost indicator lamp (PL) is turned on.

In addition, when the heater is heated and the temperature of the washer fluid reaches 60 ° C. (temperature controllable), the temperature detection relay (THR) a contact is closed, so that the defrosting completion timer (T ₁ ) and the washer pump motor time flickr relay (PM) T / FR) and wiper motor delay timer (WPM TD 1.0).

When the power is supplied, the washer fluid pump motor operates at periodic [1 sec On, 1 sec Off] to inject washer fluid, and when the frost melts, the wiper motor delay timer (WPM) prevents wiper braid burnout. Defrosting completed after ₁ second (time adjustable) by wiper motor (WPM) by TD 1.0) After defrosting timer (T ₁ ), defrosting is completed and afterwards, only wiper operates and stops for 4 seconds. Completely remove the remaining washer fluid to prevent re-freezing.

And, as shown in Figure 6 was installed a washer fluid detection switch (WS) to install the security device so that the heater is not heated if there is no washer fluid, the vehicle was left to operate the washer fluid and the wiper manually (wiper manual lever of the car) It is possible to clean the glass again with the washer liquid hot water, and also get on the vehicle and the start switch auxiliary relay (X _K ) is excited by the key switch, and the start auxiliary relay (X _S ) is demagnetized to complete the preparation of the next control circuit operation. In addition, the power consumption of the battery is prevented when the keyswitch ON, and when the key is inserted, the power supply required for driving the engine is applied through the keys, thus not affecting the function of the vehicle at all.

Also, except for the winter season, open the selector switch [S _S (Summer Off)] to prevent unnecessary heater operation, and if the generator power detection relay (X _G ) is energized after starting the engine when you want to remove it by hand only, When the heater input button switch (H-ST) is On (On), the heater is heated to remove the frost momentarily, accordingly the frost removal is completed automatically.

In addition, the manual defrosting is not interfered with the automatic start and the frost is removed in about 40 seconds, and the manual defrosting is made possible so that the battery is protected so that the battery does not interfere with other functions. , The start control circuit fuse [F _S (30A)] and the heater circuit fuse [F _H (30A)] protect the circuit, and if an abnormality occurs in the system, the main switch (MS) is opened, which does not interfere with the vehicle function. Do not give.
