Definitions
- the present invention relates to a compartment for the proportioning of the regeneration liquid in a dishwasher, equipped with a flow rate meter.
- the flow rate meter measures the flow of water flowing into the compartment in such a way that predefined quantities of water are fed to the dishwasher according to the preset washing program.
- the configuration of the walls of the compartment wherein the flow rate meter is integrated must also be suitable for containing the wheel in such a way that it can rotate freely without risks of jamming.
- an additional insert part is used, to be inserted tightly between the walls of the compartment.
- the object of the present invention is thus that of providing a compartment for proportioning the regeneration liquid in a dishwasher, equipped with a flow rate meter which eliminates the disadvantages suffered by a traditional device.
- the object of the present invention is that of providing a compartment for the proportioning of the regeneration liquid in a dishwasher, equipped with a flow rate meter, wherein the flow meter is accessible for simple inspection, maintenance or replacement.
- Another object of the present invention is that of providing a compartment for proportioning the regeneration liquid in a dishwasher, equipped with a flow rate meter which can be attached simply and rapidly to the compartment without complicating the manufacture of the compartment itself.
- Yet another object of the present invention is that of providing a compartment for proportioning the regeneration liquid in a dishwasher, equipped with a flow rate meter which creates a perfect and safe seal in relation to the body of the compartment.
- a compartment for proportioning the regeneration liquid in a dishwasher equipped with a flow meter, characterised in that the flow meter is snap-fastened outside of the compartment.
- the snap-engaging provides the possibility of adjusting insertion also for other types of meter, and not necessarily wheel meters.
- Sealing of the device is achieved through an O-ring or toroidal ring or one of another shape attached between the pipette for entrance of the water into the regeneration compartment and the delivery mouth of the wheel.
- the seal ring is simple, safe, reliable, practical to apply, economical and can be easily inspected from the outside in order to assess its structural intactness.
- Figures 1-4 illustrate the assembly of the present preferred embodiment of the invention, comprising a compartment 1 for proportioning the regeneration liquid, that is to say the liquid intended for regenerating the ion exchange resins after decalcification of the washing water, a wheel flow rate meter 3 outside of the regeneration compartment 1, and a seal member 2 of the O-ring or toroidal gasket type or the like for engaging between the inlet mouth 21 of the regeneration compartment 1 and the delivery mouth 24 of the wheel flow meter 3.
- a compartment 1 for proportioning the regeneration liquid that is to say the liquid intended for regenerating the ion exchange resins after decalcification of the washing water
- a wheel flow rate meter 3 outside of the regeneration compartment 1
- a seal member 2 of the O-ring or toroidal gasket type or the like for engaging between the inlet mouth 21 of the regeneration compartment 1 and the delivery mouth 24 of the wheel flow meter 3.
- the compartment 1 is composed of two half-shells in polypropylene, welded one to the other by means of a hot blade, and has the inlet mouth 21 on the lower end wall of the regeneration compartment 1 in a position upstream of the safety device against the return of contaminated water to the water supply system, also known as "air break", provided in a point not shown in the regeneration compartment 1.
- This positioning of the wheel meter 3 upstream of the air break is advantageous due to the fact that it allows accurate measurement of all the water entering the regeneration compartment 1, both of the water which goes beyond the air break towards the decalcifier (not shown) of the dishwasher, and of the minimal quantity of water which, via the air break, is conveyed directly towards the washing tub without passing through the decalcifier.
- the wheel flow meter 3 in a known manner, comprises a containing body formed by two half-shells 11 and 12 welded one to the other or attached for rotation with a seal gasket and a "bayonet" coupling between the two half-shells 11 and 12.
- the rotor or wheel 13, true and proper, is placed inside the containing body and which rotor or wheel in turn is composed of a plastic part, with the blades for submitting to and measuring the passing flow, and of a magnet 14, snap-fastened to the centre of the wheel.
- the flow meter 3 is clamped to the regeneration compartment 1 by special means which can be coupled reciprocally, formed on the body of the compartment 1 near the inlet mouth 21 of the compartment 1 and on the half-shell 11 of the body for containing the flow meter 3.
- the reciprocal coupling means comprise a male element defined by guide ribbing 23, formed on the body of the compartment 1, and a female element defined by a groove 27 sliding on the ribbing 23, formed on the half-shell 11 of the body for containing the flow meter 3.
- the reciprocal coupling means also comprise a retainer 22 formed on the body of the compartment 1 and a striker member 28 which can be snap-hooked by the retainer 22 formed on the half-shell 11 of the body for containing the flow meter 3.
- the housing 27 of the body for containing the meter 3 is made to slide axially on the guide ribbing 23 until it rests against the retainer 22. In this way rotation of the flow meter 3 in relation to the regeneration compartment 1 is blocked.
- the retainer 22 is snap-inserted in the corresponding striker member 28 in such a way as to block also axial translation of the flow meter 3 in relation to the regeneration compartment 1.
- the retainer 22 can be actuated manually or by means of a special tool so as to disengage from the corresponding striker member 28 in such a way as to allow release and subsequent separation of the flow meter 3 from the regeneration compartment 1.
- the regeneration compartment designed in this way is suitable, in a versatile manner, for the use of any system of metering the flow, also operatively different from that illustrated above.
- snap-fastening can also be different from that illustrated, providing male parts and female parts for coupling either on the flow meter or on the body of the regeneration compartment.
