Definitions

  • the invention relates to a device for protection against water damage in dishwashers and the like., With an inlet hose and an enveloping hose that surrounds it at a distance, which opens via a connecting hose in the washing container of the machine, and a valve connected upstream of the inlet hose, which via a program control device and a level monitor which detects the water level in the machine is controlled.
  • the envelope tube is also connected to the machine inner container, specifically with a chamber for level monitoring. From this level monitoring chamber, a pressure-dependent, Valve arranged on the machine side to shut off the inlet and, via a switching contact assigned to this valve, also controls a solenoid valve connected upstream of the inlet hose.
  • the invention has for its object to ensure beyond the damage described in DE-A 36 04 673.6 that the machine switches off when it reaches a maximum permissible level just as safely and defined as in the case of leaks in the enveloping tube.
  • the solenoid valves per se belong to the elements that can be regarded as very reliable. However, since these valves work on a pipeline network that is not always without additives, such as sand, a malfunction of such valves cannot be completely ruled out. Another object of the invention is to largely rule out damage from such faults.
  • the objects are achieved in a device of the type described above in that the machine is assigned a second level monitor, which closes at least one of two electrical valves arranged in front of the inlet hose when a maximum water level is exceeded, this level monitor is connected to a wind boiler on the rinsing tank and the connecting hose to the cladding hose via an air line that is routed above the maximum permissible water level.
  • the valve is advantageously designed as a serial double valve which is equipped with two electrically controllable elements, e.g. Solenoid coils is equipped. If you place both solenoid valves in series with the usual control elements, such as the program control unit and the level monitor for the operating level, the second level monitor for the maximum level as well as a damage event in the supply hose can be looped in with a control contact.
  • two electrically controllable elements e.g. Solenoid coils is equipped.
  • the air line and the connecting hose As a hairpin-shaped curved component, in which the connections are introduced at the front on the legs. It is also advantageous to insert the connecting hose into the air line in the region of the bend and then to bend the component twice in such a way that the connections to the level monitor, the air tank and the connecting hose are arranged side by side. This results in a compaction edge, through which pressure is built up on the level monitor in the event of a fault in the inlet, even when the machine tank is empty. A level monitor is sufficient to record the accidents.
  • the washing compartment 2 with its front door 3 is arranged in the housing 1 of a dishwasher.
  • the rinsing tank is equipped in a known manner with a sump 4, to which two air tanks 5 and 6 are connected.
  • the housing 1 On the bottom, the housing 1 is provided with a collecting trough 7, which has a float 8 and a switch 9 assigned.
  • the wastewater pump assigned to the sump 4 is not shown here.
  • the level monitor 10, which switches off the water inlet when the working level 11 is reached, is connected to the wind boiler 5.
  • the wind boiler 6 is connected via the air line 12 and the component 13 on the one hand to the connecting hose 14 and on the other hand via the air line 15 to the level monitor 16, which responds to the maximum permissible level 17.
  • the component 13 is arranged in the machine in such a way that the connection to the level monitor 16 both from the connecting hose 14 and from the air hose 12 is above the maximum permissible level 17.
  • connection unit 19 and the double valve 20 with the magnetic coils 21 and 22 are provided, which are connected by the hose lines 23, 24.
  • the tubing consists of an inlet hose 23, an enveloping hose 24 and a protective hose 25.
  • the inlet hose 23 is tightly connected to the double valve 20.
  • the enveloping tube 24 is fastened to the connection unit 19 in such a way that the closed space between the inlet tube 23 and the enveloping tube 24 has an air connection to the connecting tube 14.
  • the envelope tube 24 is enclosed by a protective tube 25 which is fastened to the connection unit 19 and the housing 26 of the valve 20.
  • the electrical wiring 27 is laid between the enveloping tube 24 and the protective tube 25.
  • the connection unit 19 has a recess for leading out the wiring 27, which are connected to control the magnetic coils 21 and 22 with the program control device and the level monitors 10 and 16 and the contact 9 of the float switch.
  • solenoids 21 and 22 are individually controlled, e.g. the valve associated with the coil 21 is opened when the main switch is actuated.
  • the valve associated with the coil 22 is switched as a function of the program control device and the level monitor 10.
  • the level monitor 16 is acted upon with a corresponding air pressure via the wind boiler 16 and the air lines 12, 15, which partly run in the component 13, so that it switches and the magnetic coil independently of the level monitor 10 21 de-excited.
  • the corresponding valve part closes.
  • the pressure at the level monitor 16 drops, so that the valve 21 can open again.
  • the component 13 according to FIG. 3 is designed as part of a water supply device in such a way that it is flat can be mounted on the side wall of the washing compartment 3.
  • a water supply device in such a way that it is flat can be mounted on the side wall of the washing compartment 3.
  • Such a unit consists of the water supply line 30, which leads via the free air gap 31 and the outlet 32 to the water softener, not shown.
  • the housing 33 forms chambers from which a certain amount of water can be passed through a valve 34 through the outlet 35 for regeneration in a salt vessel, not shown.
  • the component 13 is designed as a flat plastic body and has molded-in ribs such that the air lines 12, 15 and the connecting hose 14 can be mounted side by side.
