Definitions

  • the present invention relates to a dispenser device for dispensing service liquid, such as a liquid cleanser, into the flush water of a sanitary fixture flush tank.
  • Sanitary fixture flush tanks for WCs, urinals, etc.
  • a drain valve which is activated to drain the water from the tank into the bowl of the sanitary fixture to flush it; and a feed mechanism, which fills the tank back up to a predetermined level each time the drain valve is operated.
  • Some flush tanks are equipped with cleaning systems for adding liquid detergent/cleanser to the water drained from the tank into the bowl.
  • a dispenser device for dispensing service liquid in particular a liquid cleanser, into the flush water of a sanitary fixture flush tank, substantially as defined in the accompanying Claim 1.
  • the invention also relates to an assembly comprising the dispenser device and a flush tank drain valve, and as defined in the accompanying Claim 5; and to a flush tank comprising the dispenser device, and as defined in Claim 7.
  • the dispenser device according to the invention provides for easily, effectively and reliably dispensing service liquid (e.g. liquid detergent/cleanser) into the flush water of a flush tank. More specifically, the dispenser device according to the invention is extremely straightforward and reliable by having no moving parts or complicated mechanisms.
  • service liquid e.g. liquid detergent/cleanser
  • Number 1 in Figure 1 indicates a dispenser device for dispensing service liquid, such as (but not necessarily) liquid detergent and/or cleanser or any other type of water processing liquid, into the flush water of a sanitary fixture flush tank 2.
  • service liquid such as (but not necessarily) liquid detergent and/or cleanser or any other type of water processing liquid
  • dispenser device 1 is associated with a drain valve 3 of tank 2 to dispense the service liquid into the flush water drained from tank 2 by drain valve 3.
  • Drain valve 3 is a known type and only shown schematically in Figure 1 . Roughly speaking, drain valve 3 comprises a supporting structure 5; a slide 6 fitted to structure 5 and which slides vertically along an axis X; and an actuating mechanism 7, which acts on slide 6.
  • Structure 5 is connectable to a bottom wall 8 of tank 2, e.g. by means of a substantially tubular drain sleeve 9, which is inserted inside an opening 10 in bottom wall 8, and defines a drain hole 11 of tank 2; sleeve 9 is bounded by a lateral.wall 12, and has a top annular edge 13 defining a sealing seat 14; and sleeve 9 defines a first portion of a drain pipe 15 (the rest not shown) connecting tank 2 to the sanitary fixture.
  • Slide 6 extends along axis X, and slides inside a guide 16 formed on structure 5.
  • slide 6 comprises an open tubular body 17, which also acts as an overflow pipe of tank 2.
  • slide 6 has a shutter 18 which cooperates' with sealing seat 14 to close drain hole 11.
  • Slide 6 is raised by mechanism 7, which is substantially known and not shown in detail for the sake of simplicity.
  • dispenser device 1 comprises a feed tank 20 containing a measure of service liquid; a delivery pipe 21 connecting feed tank 20 to drain hole 11; and an inlet pipe 22, which connects feed tank 20 to a service liquid reservoir (not shown), and feeds service liquid to feed tank 20.
  • Feed tank 20 extends parallel to axis X, between two opposite longitudinal ends 23 and 24.
  • feed tank 20 is bounded by a lateral wall 25 and a bottom wall 26, and is open at the top end 24.
  • Feed tank 20 is housed, for example; inside flush tank 2, and is so positioned as to prevent the water in flush tank 2 from entering feed tank 20 through open top end 24.
  • the top end 24 of feed tank 20 is therefore located above a level L1 constituting the maximum fill level of flush tank 2.
  • Feed tank 20 is also located higher than sleeve 9 and at least partly below level L1, i.e. is partly immersed in the water inside flush tank 2 in normal operating conditions (when the flush tank is full and ready for use).
  • Feed tank 20 has an inner chamber 27 containing the measure of service liquid to be dispensed into the flush water from flush tank 2; and a channel 28. connecting chamber 27 to delivery pipe 21.
  • Channel 28 has an inlet 31 located at bottom end 23 of feed tank 20 and communicating with chamber 27; and an outlet 32 located at top end 24 of feed tank 20 and connected to delivery pipe 21. Outlet 32 is located higher than inlet 31.
  • channel 28 comprises a bottom base portion 33 located inside feed tank 20 and having inlet 31 close to bottom wall 26 of feed tank 20; and a top fitting 34, e.g. an elbow fitting, having outlet 32.
  • Fitting 34 has a connecting portion 35 that fits in fluidtight manner inside a top seat 36 of base portion 33; and a connecting portion 37 that is engaged by (fits inside) delivery pipe 21.
  • Delivery pipe 21 defined for example by a hose, connects outlet 32 to drain hole 11, and more specifically connects connecting portion 37 of fitting 34 to a lateral branch opening 38 formed in lateral wall 12 of sleeve 9 and bounded by a collar 39 onto which delivery pipe 21 fits.
  • Branch opening 38 is formed downstream from (i.e. is axially lower than) sealing seat 14 and shutter 18.
  • Channel 28 and delivery pipe 21 define a siphon system 40 connecting chamber 27 to drain hole 11.
  • Inlet pipe 22 communicates with chamber 27 through a hole 41 formed, for example, in lateral wall 25 of feed tank 20 and located at an intermediate height between inlet 31 and outlet 32.
  • flush tank 2 when full and ready for use, contains water up to level L1; and feed tank 20 contains a measure of service liquid occupying chamber 27 and channel 28 up to a level L2, which may for example (though not necessarily) be substantially equal to level L1.
  • drain valve 3 When the water is drained from flush tank 2 by activating drain valve 3 (by raising slide 6 and shutter 18 by means of mechanism 7 to open drain hole 11), the water flows out of flush tank 2 through drain hole 11.
  • the water flowing into sleeve 9 flows up along delivery pipe 21. More specifically, the water flows through branch opening 38 and up along delivery pipe 21 to a predetermined height, i.e. to substantially the same (falling) level as the water inside flush tank 2.
  • the water flowing into delivery pipe 21 pushes the air in delivery pipe 21 along channel 28 into chamber 27 and the service liquid.
  • the water does not reach outlet 32, however, and so does not flow into chamber 27 or feed tank 20.
  • the out-flowing water siphons the service liquid from chamber.27 through the siphon system 40 formed by channel 28 and delivery pipe 21.
  • the service liquid is fed into the flush water inside sleeve 9 (i.e. into drain pipe 15) through branch opening 38, i.e. downstream from drain valve 3.
  • Siphon system 40 therefore defines a hydraulic path for selectively:
  • chamber 27 is practically empty or only contains a residual amount of service liquid.
