Definitions
- the present invention relates to washing machines or dishwashers provided with a flood-preventing device, and in particular to such a machine provided with a member which allows to check the working of said device.
- washing machines or dishwashers for domestic use are generally provided with a flood-preventing device whose function is to stop the entrance of water coming from the hydraulic network in case of leakage from any component of the machine.
- This device substantially consists of a tray located at the bottom of the machine, where the possible leak is collected, and a float placed in the tray which activates a microswitch when raised.
- the activation of the microswitch causes the closure of the water inlet valve and usually also the activation of the drain pump, so as to prevent the risk of flooding.
- the object of the present invention is to provide a washing machine or dishwasher suitable to overcome the above-mentioned drawbacks.
- the main advantage of the machine according to the present invention is to allow a simple and safe way for a systematic check of the working of the flood-preventing device. This obviously results in a dramatic increase in the reliability of said device.
- a further advantage of the present machine is that it does not require significant changes in order to achieve said function, whereby the costs and production processes remain substantially unchanged.
- a dishwasher conventionally includes a bottom tray 1 wherein, at an almost central position, there is placed a float 2.
- the tray I can collect a possible water leak from any component of the machine, such as the pump 3, the duct which feeds the sprinkler 4, the chamber 5 at the bottom of the tank, etc.
- the microswitch 6 is mounted above the float 2 so as to be activated as soon as the water collected in the tray 1 causes a little raising of the latter (dotted line in fig.2).
- the novel aspect of the machine according to the present invention is a deformable diaphragm-shaped member 7 which water-tightly closes a hole formed in the tray 1, preferably at the center of the float 2.
- This hole allows to check the working of the flood-preventing device by simply mechanically pushing upwards the float 2 through deformation of the diaphragm 7. This type of check can easily be made automatic and carried out directly on the production line in a systematic manner, that is on 100% of the machines.
- the member 7 in particular is provided with a peripheral crown 7a having a seat for the fitting thereof on the thickness of the tray 1, as well as a central peg 7b projecting upwards close to the float 2 so as to minimize the deformation required for the check.
