Definitions
- the invention relates to a water-bearing household appliance according to the preamble of claim 1.
- a sensor in the form of a floatable body Switch that responds when leak water occurs and one into a feed line for filling one Shut-off valve in the Closed state controls and, if applicable, one of the liquid containers switches on the assigned drain pump.
- the liquid container is also a level control device associated with a predetermined fluid level corresponding control of the shut-off valve. Failed a level sensor of the level control device so the liquid container overflows and the overflowing Liquid is drained from the drain pan fed. The liquid collected there actuates the float controlled switch, eliminating the safety measures mentioned be started.
- This monitoring device has the disadvantage that it cannot be reset automatically after a response is because the amount of liquid in the drip pan only by appropriate assembly measures, preferably can be removed by a specialist.
- the level control relevant factors e.g. unfavorable constructive Design of the device, unfavorable tolerance or extreme Installation conditions of the device, it may under certain circumstances overflow of the liquid container too come with properly functioning level control. This can be the case in particular if the level control in a parallel to the liquid container Level control vessel takes place in which after the principle of communicating tubes the same liquid level as set in the liquid container.
- the operator opens during a The device, e.g. for further wash items and then closes the machine again, an overpressure arises in the liquid container, which Liquid displaced into the level control vessel, causing there the liquid level rises and when it reaches the level control vessel arranged safety overflow edge liquid is directed into the drip pan.
- the object of the invention is therefore a water-bearing Specify household appliance, at which a security level assigned monitoring device only then responds when a level control setting an operating level fails.
- This object is achieved according to the invention with a water-bearing household appliance with a security level assigned monitoring device, which according to a response cannot be reset automatically, that another filling quantity monitoring device is provided which one between an operating level and assigned to the security level lying monitoring level is. If there is a temporary operational or increases caused by the operator of the machine the liquid level, so speaks the other Filling quantity monitoring device and takes measures in progress, which cause the fluid level does not continue to rise to the safety level, so that also not the one assigned to the security level automatically resettable monitoring device responds.
- the further filling quantity monitoring device preferably comprises a storage container, which when the Monitoring levels the further rising liquid can be supplied is. This way there will be a further increase of the level up to the security level prevented.
- this storage container due to the existing in the device constructive conditions are not large enough can be dimensioned, it is advantageous in the storage container to arrange a float body on one assigned switch acts.
- This switch can then a drain pump can be switched on, which the At least the amount of liquid in the liquid container partially reduced by pumping.
- a drain pump also an inlet valve through which the liquid container Fresh water can be supplied, switched off. This is particularly effective when the further Filling quantity monitoring device during the filling phase appeals.
- the invention is based on the drawing of a Embodiment explained in more detail.
- the drawing shows schematically a water inlet vessel a household dishwasher with one arranged therein Liquid level control.
- a not shown liquid container Household dishwasher is by means of a water supply line 2 and a water inlet tank connected to it 1 fed with fresh water.
- the water supply vessel 1 is by means of a connecting pipe 6 with the liquid container connected to conduct liquid. That in Liquid tank is reflected in the operating level itself in the water supply vessel 1 due to the law of communicating tubes arranged in a water inlet vessel 1 Level control reflected.
- the level control comprises a safety level monitoring device 5, 13, which with an impermissibly increasing Amount of liquid and reaching a safety level 4 responds. This is done by that the security level 4 is assigned an overflow edge 5 over which the rising liquid passes. The spilled liquid is then piped 13 and a sump not shown fed. In this collecting pan sits in a known manner a float switch, which is also known Initiates security measures.
- the level control also includes a further filling quantity monitoring device 7, 8, 9, 10, which in one between operating level 3 and security level 4 lying monitoring level 14 addresses.
- the surveillance level 14 is assigned a second overflow edge 7, whose exceeding a filling of a reservoir 8 for Consequence.
- a float body sits in this reservoir 8 9, which floats when filling the reservoir 8.
- the drain pump then pumps liquid for as long out of the liquid container until the float body 9 due to automatic removal of the liquid in the reservoir 8 drops again and the microswitch 10 restored to its original state.
- the storage container 8 is emptied via a siphon-like suction lifter 11, which when the Operating levels 3 simultaneously the liquid in the reservoir 8 removed.
