Definitions

  • the invention relates to an additional device for washing machines, which is arranged externally without intervention in a control existing in the washing machine and which has a mains connection for the washing machine.
  • a very simple way of saving detergent and energy is to interrupt the main washing process again and again at fixed intervals. As a result, the detergent dissolves better, so that detergents based on soap can be used. You can also wash with a lower water temperature.
  • the additional equipment available on the market only has a timer, which is set to a certain time after the prewash has ended, so that warm water can run in until the end of the expiring time (without temperature control).
  • the invention has for its object to provide an additional device of the type mentioned so that the greatest possible optimization of the consumption of energy, water and detergent is achieved without intervention in the control of the washing machine.
  • a mixer with a hot water connection and cold water connection and further a pressure sensor and a temperature sensor are provided for connection to the water inlet of the washing machine, that the additional device has a control unit in which an ammeter determining the current consumption of the washing machine is arranged and that the control device has a computer for interrupting the power supply of the washing machine on the basis of the information about its current consumption and the pressure signals.
  • Such an additional device is able to optimally control the washing machine on the basis of the information supplied to it about the power requirement of the washing machine and the pressure surges in the water inlet, without having to intervene in the control existing in the washing machine.
  • the additional device can, for example, by controlling solenoid valves of the mixer on the basis of temperature signals from an additional temperature sensor, ensure that the washing machine is supplied with water at the correct temperature for its desired washing program, so that the electric heating of the washing machine does not have to work. Only if the water temperature at the hot water connection is not sufficient will the washing machine's heating switch on automatically.
  • the hot water connection can be supplied by oil heating or a solar roof, for example.
  • the additional device can thereby easily recognize whether, for example, the prewash program or main wash program is running in the washing machine, that the pressure sensor is designed to register the pressure peaks occurring when the water inlet closes, and a counter is provided in the control unit for counting the pressure surges. As a result, the additional device is able to decide whether the washing machine must be supplied with water at a low temperature for the prewash or at a high temperature for the main wash.
  • the washing machine programs are usually designed so that a desired washing process can be started at any point within the washing machine program. For example, you can start directly with the main wash and then run the normal washing program with the rinsing and spinning processes. In such cases, it is of course necessary that the additional device takes into account the entry point into the washing program. This can be done in a simple manner in that the control device is designed to be adjustable to the washing program of the washing machine selected in each case.
  • a washing machine can work in a particularly environmentally friendly manner with the additional device according to the invention if the additional device is at the same time designed to control a rainwater connection for the washing machine.
  • the desired extension of the main wash cycle through interval intervals can be set in a simple manner in that the control device has a time selector switch for setting the desired total duration of the interruptions in the main wash cycle.
  • control device has a temperature selection switch for setting the water temperature desired during the main washing cycle.
  • the additional device has a water monitor for detecting water collecting on the floor and the computer is designed to switch off any water supply and power supply to the washing machine.
  • the invention allows numerous embodiments. To further clarify its basic principle, one of them is shown schematically in the drawing and is described below.
  • the drawing shows the outline of a washing machine 1, which has a conventional water inlet 2 and a power cord 3 with a power plug 4.
  • a mixer 5 is connected, which is connected to a hot water connection 6 and a cold water connection 7.
  • Solenoid valves 8, 9 can control the amount of cold and warm water flowing in.
  • a temperature sensor 10 and a pressure sensor 11 are also connected in the connection from the mixer 5 to the water inlet 2.
  • control unit 12 which has a mains plug 13 and a plug contact 14.
  • the mains plug 4 of the washing machine 1 can be plugged into this plug contact 14 so that it can be supplied with electrical energy via the control device 12.
  • a computer in the control unit 12 which controls the power supply to the washing machine 1 on the basis of the temperature signals of the temperature sensor 10, the pressure signals of the pressure sensor 11 and the information about the power consumption of the washing machine, which is supplied by an ammeter installed in the control unit.
  • a selector switch 15 is provided on the front of the control device 12, with which one can set the washing process with which the program is to start, in accordance with the setting made on the washing machine 1. Furthermore, the control device 12 has a timer 16, with which the total duration of the interruptions in the main washing process can be set. In addition, a temperature switch 17 is provided, which allows the temperature of the water supplied to the washing machine 1 to be adjusted.
  • a rainwater connection 18 is provided on the mixer 5, via which, controlled by a solenoid valve 19, rainwater can be supplied from the cold water connection 7 to the washing machine instead of drinking water. Drinking water is then only used for the last rinsing process.
