Definitions
- the present invention relates to dishwashers, and in particular to a cleaning cycle for a dishwasher provided with a device for recycling the rinse water and/or the wash water.
- the normal operating cycle substantially consists of the pre-wash, wash, intermediate rinse, final rinse and drying phases.
- the initial pre-wash phase is useful to remove the largest residues from the dishes and the water used in said phase is then drained and replaced with clean water for the subsequent wash phase.
- dishwashers provided with such a rinse water recycling system are found in US 2007-0277854A1 and DE 4243605A1 , that disclose hydraulic connecting systems between the storage reservoir and the wash tank in which there is provided a specific valve that closes and opens the access to the reservoir or a two-way valve that directs the rinse water towards the reservoir or towards the drain pipe.
- said cleaning cycle provides the empty operation of the dishwasher with the load of the same amount of water used in the normal operating cycle and without recycling the rinse and/or wash water. Therefore the cleaning cycle affects only the parts usually contacted by the water in the normal operating cycle such as the wash tank, wash and drain pumps, load and drain pipes but not the rinse water storage reservoir that thus keeps accumulating dirt.
- the object of the present invention is to provide a cleaning cycle, for a dishwasher that performs the water recycling function, which overcomes the above-mentioned drawbacks.
- This object is achieved by means of a cycle that provides also the opening of the hydraulic connection towards the storage reservoir as well as the loading of an amount of water sufficient to guarantee the correct operation of the wash pump without cavitation even when said reservoir is full.
- Other advantageous features of the present cleaning cycle for dishwasher are disclosed in the dependent claims.
- the main advantage of this cleaning cycle resides in the fact that by loading the water also in the storage reservoir without having this cause the cavitation of the wash pump it is possible to remove the dirt residues from said reservoir so as to achieve a complete and accurate cleaning of the machine.
- a dishwasher implementing a cleaning cycle according to the present invention is conventionally provided with a wash pump 1 that draws the water from the collecting sump and sends it, through a pipe 2, towards a storage reservoir 3 extending in the side portion of the dishwasher, between the wash tank and the external casing.
- Said reservoir 3 includes an inlet passage 4 separate from an outlet passage 5, each passage being controlled by a respective valve 6 and 7, which converge downwards into the single connection to pipe 2.
- Reservoir 3 further includes a load duct 8 extending from the inlet passage 4 to the top of reservoir 3.
- a flowmeter e.g. in the form of a turbine 9, is preferably arranged in the load duct 8 to precisely measure the amount of water loaded in reservoir 3 and consequently control the stopping of the wash pump 1. It should be noted that, upon entry of the water, the air present in reservoir 3 is vented through the vent duct 10 connected to the wash tank through collar 11.
- valves 6, 7 are usually driven by thermoactuators that must not exceed given operating times, it is possible that the flow of water through reservoir 3 is interrupted and restored during the cleaning cycle in order to allow the closing and re-opening of valves 6, 7 so as to comply with said operating times. This does not affect the cleaning effectiveness in that, in designing the cycle, the correct valve operating times are obviously taken into consideration so as to obtain a sufficient duration of the wash and rinse steps of reservoir 3.
