Definitions

  • the invention relates to a safety device for connecting a water-carrying household appliance to a water supply network with a network-side connection fitting.
  • the current practice foresees a solenoid valve at the beginning of the aquastop and thus at the tap. From there, the water runs in a pressure hose, which in turn is guided in a hose, to the back wall of the water.
  • This solenoid valve is supplied with voltage via two control lines.
  • Two further solenoid valves which can be controlled for prewashing on the one hand and the main wash on the other hand and thus for a demand-oriented water supply, are located on the back of the appliance. Of these Both solenoid valves each have a hose to the local water switch in the dispenser tray. These hoses running in the household appliance no longer have to be pressure-resistant, since they are open at the end which opens into the dispensing bowl.
  • the known safety devices are relatively expensive material and therefore costly.
  • a safety device is designed to connect a water-conducting domestic appliance to a water supply network with a mains-side connection fitting. At the connection fitting a first waterway shut-off element and a second waterway shut-off element are arranged. Each of these waterway shut-off is connected to an associated, formed for water supply hose, these hoses lead to the household appliance.
  • a component-reduced safety device is provided, since only two waterway shut-off elements are required. In comparison to known safety devices, therefore, at least one waterway shut-off element can be saved. As a result, a solution that is as cost-effective as possible and mountable with a reduced outlay is made possible, and a safety device designed with at least the same aquastop functionality in comparison with the prior art is provided. Reliable protection against water damage can be guaranteed.
  • the two hoses which lead from the waterway shut-off to the household appliance and continue in the home appliance, designed as non-pressure-loaded hoses.
  • non-pressure-loaded hoses are therefore not understood pressure hoses.
  • These non-pressure-loaded hoses are designed to withstand low pressures or no pressure compared to pressure hoses. For the water supply Thus, such non-pressure-loaded hoses are used throughout, so that a cost savings can be achieved here as well.
  • the risk of bursting of the hoses as may occur in the case of pressure hoses, can be excluded.
  • the two separate, leading from the two waterway shut-off to the home appliance hoses are performed with their opening into the household appliance ends in a container of the household appliance and formed open to these opening into the household appliance ends.
  • these ends of the two hoses are guided in a water switch of this container. If the domestic appliance is designed as a washing machine, these two open ends open into a water separator in an induction bowl. This also at least supports the non-pressure-resistant design of the hoses.
  • the container in the domestic appliance comprises an overflow system. This can further reduce the risk of water damage.
  • the two waterway shut-off elements are electrically controllable valves, in particular solenoid valves.
  • the two electrically controllable valves are controllable by means of a control unit arranged in the household appliance. Even more preferably, it is provided that at least one control line for controlling the waterway shut-off elements, in particular of the valves, runs from the domestic appliance, in particular the control unit, to the waterway shut-off elements.
  • the hoses designed for the water supply and the at least one control line between the connection fitting and the household appliance are surrounded by a protective hose, in particular a double-walled protective hose.
  • a protective hose in particular a double-walled protective hose.
  • the control line and the two tubes designed for water supply can be protected from damage.
  • a high-quality and a compact tidy impression can be conveyed outside the household appliance by this attachment of a protective tube.
  • the first waterway shut-off and the associated hose for a water supply during a first phase of operation of the domestic appliance and the second waterway shut-off and the associated hose for a water supply during a second phase of operation of the domestic appliance are formed and controlled in particular for the corresponding water release or water shut-off.
  • the first operating phase of the household appliance is preferably a prewash and the second operating phase is a main wash. This is particularly advantageous in a configuration as a household appliance for the care of laundry items, especially as a washing machine.
  • the domestic appliance can also be designed, for example, as a dishwasher.
  • the safety device according to the invention advantageously now also makes it possible to use hoses that are not pressure-loaded on the entire waterway.
  • This compared to explicitly designed as pressure hoses not loaded with high pressure hoses are preferably designed so that in a design of the household appliance as a washing machine, the detergent is still relatively well rinsed and works the water diverter for the fabric softener in the dispenser well accordingly. Since the inlet system is open on the dispenser, no permanently high pressures can occur in the tubes and they must therefore not meet increased pressure requirements.
  • the safety device according to the invention or an advantageous embodiment thereof are also suitable for the guidance of hot water.
  • a safety device 1 for connecting a water-carrying household appliance 2, which is formed in the embodiment as a washing machine, to a water supply network 3 with a network-side connection fitting 31, which is designed as a faucet shown.
  • a first solenoid valve 11 and a second solenoid valve 12 are arranged.
  • the outside and separately to the domestic appliance 2 arranged solenoid valves 11 and 12, which are arranged on the connection fitting 31, are each connected to a hose formed for water supply.
  • the first solenoid valve 11 is connected to a first hose 13 and the second solenoid valve 12 is connected to a second hose 14.
  • the two tubes 13 and 14 are guided via an insertion device 15 in the interior of the household appliance 2 and open there in a water diverter, not shown, a dispenser 16.
  • the two ends 13a and 14a of the tubes 13 and 14 opening into the dispensing tray 16 are open.
  • the two tubes 13 and 14 are designed as non-pressure-loaded hoses.
  • the dispenser tray 16 also has an overflow system, not shown.
  • the two solenoid valves 11 and 12 are electrically controlled via a control unit 21 arranged in the household appliance 2.
  • a control unit 21 arranged in the household appliance 2.
  • at least one control line 22 is provided in the exemplary embodiment, which extends from the control unit 21 to the solenoid valves 11 and 12. In the embodiment, a wired control is thus provided.
  • control line 22 is led out in the region of the element 15 from the domestic appliance 2 and laid to the solenoid valves 11 and 12.
  • Both the control line 22 and the two tubes 13 and 14 are surrounded by a double-walled protective tube 17, so that both the at least one control line 22 and the two tubes 13 and 14 are protected outside the domestic appliance 2.
  • the exemplary illustrated control line 22 may also be a multi-line system and include, for example, two or three or more control lines.
  • the first solenoid valve 11 and the associated hose 13 for a water supply during a first operating phase, which corresponds to a prewash of the domestic appliance 2 in the embodiment, by means of the control unit 21 can be controlled.
  • the second solenoid valve 12 and the associated second hose 14 are for controlling the water during a second operating phase, which corresponds in the embodiment of a main wash of the domestic appliance 2, controlled by the control unit 21.
