Definitions

  • the present invention relates to a dishwasher comprising a three-way valve suitable for use in the dishwasher which has a water softening unit for softening tap water and a salt container for regenerating an ion exchange material, in particular a resin of the softening unit.
  • Tap water for use in the washers, for instance the dishwashers, the laundry washing machines, etc. is usually relatively hard. Hard water adversely affects the washing process. For instance if the dishes are washed with hard water, white precipitates are formed on the dishes so that they appear cloudy in a dishwasher. In addition, hard water causes scale formation and damages the dishwasher. Therefore, it is generally important to use soft water in dishwashers.
  • an ion exchange material in particular a resin is utilized to absorb calcium and magnesium ions in the tap water. It is customary to provide dishwashers with built-in water softening units which use resin for softening tap water.
  • the softening capacity of a resin is limited. Therefore, the resin must be replaced from time to time. Alternatively, the softening capacity of the resin can be restored by treating the resin with brine. This treatment is also referred to as "regeneration".
  • Dishwashers in which the resin can be regenerated have a refillable salt container for supplying brine to the softening unit. Such dishwasher are controlled to intermittently perform a regeneration process.
  • EP 0 741 991 A1 discloses a dishwasher which has a resin container for storing resin to reduce the degree of water hardness.
  • the dishwasher also includes a salt container for storing salt which is required for the regeneration of the resin.
  • the resin container is fluidly connected with the washing tub by a pipe which opens into a sump that is located on the bottom of the washing tub.
  • the sump is fluidly connected to a discharge line for drainage and two sprayer arms.
  • GB1462952 A discloses a dishwasher comprising a valve.
  • An objective of the present invention is to provide a cost-effective and operationally reliable valve for use in a dishwasher for the purpose of selectively feeding the regeneration water and the softened water which are output by a water softening unit to separate lines.
  • Another objective of the present invention is to provide a dishwasher in which the valve of the present invention is specifically used for protecting the washing tub from the corrosive effect of the regeneration water which is output by a softening unit.
  • the three-way valve of the present invention comprises a valve chamber which includes an inlet port, a first outlet port and a second outlet port.
  • the inlet port is suitable for receiving softened water or regeneration water delivered from a water softening unit of a dishwasher.
  • the first outlet port and the second outlet port are both in fluid communication with the inlet port.
  • the first outlet port is arranged at a first position.
  • the second outlet port is arranged at a second position which is higher than the first position.
  • the three-way valve of the present invention further comprises a valve member which is provided in form of a float. The valve member is movably arranged within the valve chamber between the first position and the second position. At the first position, the first outlet port is entirely obstructed by the valve member and the second outlet port is open.
  • the first outlet port is open and the second outlet port is entirely obstructed by the valve member.
  • the mass and the volume of the valve member are configured such that when the valve chamber is filled with softened water, the gravity force which acts on the valve member exceeds the buoyancy force which acts on the valve member so that the valve member is held at the first position.
  • the mass and the volume of the valve member are also configured such when the valve chamber is filled with the regeneration water, the buoyancy force which acts on the valve member exceeds the gravity force which acts on the valve member so that the valve member is held at the second position.
  • valve member is movably supported by a guide means which is arranged inside the valve chamber.
  • valve member is guided upwards through the resultant action of gravity and buoyancy when the valve chamber is filled with the regeneration water.
  • the valve member is guided downwards through the resultant action of gravity and buoyancy when the valve chamber is filled with softened water.
  • the walls of the valve chamber configure a guide which guides the valve member upwards or downwards.
  • the valve member has a shape which fits between the walls of chamber. A small clearance is provided between the walls of the valve chamber and the valve member. Thereby, the valve member can smoothly move upwards or downwards like a shuttle between the outlet ports.
  • the valve chamber has two subchamber which are maintained in fluid communication.
  • the inlet port opens into a first subchamber.
  • the outlet ports branch off from the second subchamber into which the valve member is movably arranged.
  • the first subchamber and the second subchamber function like a floodgate. Thereby, a response of the valve member to the incoming water is improved.
  • each of the outlet ports has a seat.
  • the valve member has a sealing means which is configured to abut against a respective seat so as to inhibit the flow through the respective outlet port.
  • the seats and the sealing member have a matching form. Thereby, a leak-tight engagement between the valve member and the respective outlet ports is attained.
  • valve member is provided in form of a block-shaped float.
  • the sealing means is configured by two seal members which are respectively arranged on an upper surface and a lower surface of the block-shaped float.
  • valve member is provided in form of a ball-shaped float.
  • the sealing means is configured by an outer surface of the ball-shaped float.
  • the ball-shaped float easily abuts against the outlet ports which are respectively formed at the deepest and the highest locations of the valve chamber.
  • the dishwasher of the present invention includes a softening unit for softening tap water, and a salt container for regenerating an ion exchange material, in particular a resin within the softening unit.
  • the dishwasher of the present invention further includes the three-way valve of the present invention.
  • the three-way valve is arranged on a downstream side of the water softening unit to selectively conduct the regeneration water and the softened water which are output by the softening unit to different lines.
  • the three-way valve specifically conducts the regeneration water directly into a sump of the dishwasher to be drained off outside the dishwasher by a pump without being circulated within a washing tub. Thereby, the washing tub is protected from the corrosive effects of the regeneration water.
  • the dishwasher of the present invention further includes a water inlet for delivering the softened water into the washing tub.
  • the water inlet is arranged on a wall of the washing tab at a location above the sump.
  • the three-way valve specifically conducts the softened water to the water inlet. Thereby, softened water can be directly delivered into the washing tub without being mixed with any residual water in the sump.
  • the water inlet has a nozzle which sprays the softened water towards a detergent dispenser.
  • a content of the detergent dispenser can be completely flushed into the washing tub. Consequently, a decrease in the cleaning performance is avoided.
  • a risk that any residual detergent in the detergent dispenser mixes later on with the rinsing water is also avoided. Consequently, the rinsing performance is improved.
  • the three-way valve of the present invention operates through the action of gravity and buoyancy. Therefore, the three-way valve is trouble-free and easy-to-install in comparison to a conventional valve system which is electrically driven by additional control equipment.
  • the three-way valve of the present invention enables feeding the regeneration water and the softened water output by the softening unit to different lines. Thereby, the dishwasher can be protected from the corrosive effects of the regeneration water. In addition the softened water can be separately utilized at other stations in the dishwasher without being initially passed through the sump. Thereby, the dishes are treated hygienically.
