FR2503411A1 - Electrical controller for high pressure water jet sanitary cleaner - includes low voltage remote controls for water and soap pumping motors with variable setting switch-off timer - Google Patents

Abstract

The electrical control system includes an electric water pump which is remotely controlled by a push-button, and an electric soap pump similarly controlled by a push-button. A transformer is included so that the push-buttons use only 24v to control relay switches and indicator lights. A water level sensor is included in the circuit which controls the water pump. A timer is also included in the circuit, to allow operation of the machine for a certain number of minutes before automatically switching off. The system isused for high pressure spray nozzle type sanitary cleaning with a rinsing and sudsing cycle.

Description

b / The present invention relates to sanitary washing machines, by udder
high pressure tolet-jet, using soap and water.

c / In known devices of this kind, the washing system must stop
after stopping the pistdlet> jet, after 2 minutes. But the time relay, must stop the system, does not work, after some time, which causes the wear of the machine, which works without stopping. Also, the control switches, deteriorate by humidity, and by themselves, put the system E on, which causes the wear of the belt, the pump, and the valve c discharge, and burns the motor and pump. Also therefore, the labor and spare parts are too expensive for the user.

 On the other hand, the spray gun-lance is provided at its end with a double nozzle, which often breaks, and the disadvantage is, that the user cannot distinguish, what is the position of the nozzle for the - SOAP -, from that of - RINSING -, and sometimes, the user is showered himself, by a manufacturing defect, of the pistol-lance with double nozzle.

Also, despite the warning, the operator always forgets to stop the machine by the switch on his station, after using the jet,
if the time relay is broken, the system continues to operate without stopping d / According to the invention the wiring of the device is simple and easily repaired much less expensive, of simple use and functioning better than existing systems.

 According to the invention, the pistol-lance is with a single nozzle, and the operator chooses either the "SOAP" washing cycle or the "RINSING" cycle, using the remote control push-button of his station. This operation can be carried out from each cleaning station.

The device according to the invention comprises a timer, and if for example the timer being set for 10 minutes, the operator chooses the "SOAP" washing cycle and stops after having used it for 7 minutes, according to the invention , the important thing is that the soap pump-motor will stop after 3 seconds, by 1 float device, while the water-pump motor will stop after 3 minutes by the circuit cycle of the timer, if the operator forgets to stop the system by pushing button 1 on his station, as soon as he has finished using it, this operation can be carried out from each washing station
To restart the machine, simply reset the push button
"ON" (1) command of the timer cycle.

e / The attached drawing is the diagram of the FLOAT STOP system.

To start the machine, first put it in position
ON - the main switch (14) on the control box.

 Then turn on the switch (13), (where the switches, if applicable), which controls the motor-soap pump, on the control unit.

 To use the remote control device, a cleaning station, simply press the push button (1), indicating - ON -, which by the circuit of the remote control switch (2) and the timer (3) supplies the coil of the contactor (4) which starts the water pump motor. Immediately the 24 V occupancy indicator (6) will light up on all stations, to warn that the system is in operation. The motor-pump unit is thus started, and you can wash without soap.

 Then, if the user chooses to wash with soap, it suffices to press the push button (7) indicating "SOAP or RINSING"; immediately, the 24 V warning light (9) will light up, indicating that the SOAP cycle is on.

 Pressing the push button (7) again returns to the - RINSING - position where, washing without soap, and the indicator (9) will go out.

 For the user, the indicator (9) is a benchmark, to know if the "SOAP" cycle is running or not. If the light (9) is not lit, that is to say that the "SOAP" cycle is stopped. What is - IMPORTANT - is that, even if the indicator (9) of the "SOAP" cycle is on, the soap motor-pump will not operate as long as the spray gun remains closed.

 At the start of washing, the soap pump-motor will be supplied by the float (10) and contactor (11) cycle.

 the "SOAP" control push button (7) cannot be used before the start push button (1).

 This device - FLOAT - is mounted on the machine's water tank.

 For the washing by "SOAP" cycle, by pressing the trigger of the gun, the motor-pump (5) draws water from the tank, the level of which drops, and the float (10), falling, makes contact and feeds the coil switch (11) which in turn supplies the soap pump motor (12).

The device, object of the invention, can be applied to any machine
sanitary washing, by high pressure jet, with soap or detergent.

This electrical wiring diagram will be easily performed on all machines of this kind, in industry, supermarkets, garages and all positions
Sanitary, Laboratories, Hospitals etc ...
