Definitions
- the present invention relates to a household drip coffee maker comprising a cold water tank supplying a continuous circulation water heater, and a device intended to treat the water contained in the tank from an anti-scale agent. soluble or in solution.
- the water treatment device comprises a cartridge which is arranged in the filling mouth of the tank while being entirely maintained above the maximum filling level of the tank, which has a cover and a perforated bottom, and which contains a soluble anti-scale agent, of the type usually constituted by one or more polyphosphate crystals, the dissolution of which can only take place during the rapid flow of water when filling the tank.
- a soluble anti-scale agent of the type usually constituted by one or more polyphosphate crystals, the dissolution of which can only take place during the rapid flow of water when filling the tank.
- the amount of phosphorus added comes to exceed the value authorized by the legislation currently in force according to which the phosphorus concentration in water must be lower than 5 mg / 1 expressed in P 2 0 5 .
- the object of the invention is in particular to remedy these drawbacks and to produce a household drip coffee maker equipped with a water treatment device from a soluble or solution-free anti-scale agent, the amount of which added in the water is perfectly controlled in accordance with the legislation in force, regardless of the frequency of use of the coffee maker and the solubility of the anti-scale agent.
- the water treatment device comprises a device for micro-dosing of a quantity of anti-scale agent which is determined as a function of the volume of water supplied to the water heater and which is injected into water. .
- the quantity of anti-scale agent injected into the water is now controlled with high reliability and, moreover, following its injection at a very low dose, has the unexpected effect of delaying considerably in time the scaling of the coffee maker water heater.
- FIG. 1 is a partial schematic view. in vertical section of a coffee maker according to the invention comprising a water treatment device, the tank of the coffee maker being filled with water;
- FIG. 2 is a view similar to Figure 1, showing the partially emptied water tank;
- FIG. 3 is a view similar to Figure 2, after complete emptying of the tank;
- FIG. 4 shows, depending on the number of li- very water poured into the tank of the same coffee maker, the evolution of the time of passage of water in the coffee maker when the latter does not include a device for water treatment (curve A), when the coffee maker has a water treatment device maintained above the maximum filling level of the tank (curve B), and when the coffee maker has a water treatment device conforming to the invention (curve C); and
- FIGS. 5 and 6 show an embodiment of a water treatment cartridge comprising a flask of anti-scale agent in liquid form and a cap, respectively before assembly ( Figure 5) and after assembly ( Figure 6) of the cap on the bottle.
- FIGS. 1 to 3 only part of a drip-type household coffee maker has been represented, comprising a cold water tank 1 with a capacity defined by a maximum filling level referenced by N and of which the outlet 2 forming a mouth made in the bottom wall 4 is connected, via a non-return valve 5, to the inlet of an electric heating body formed by a water heater 6 with continuous circulation, the outlet of which feeds by an ascending tube 7 a watering spout a filter (not shown) intended to receive ground coffee and placed above an infusion collecting jug (not shown).
- the coffee maker illustrated in FIGS. 1 to 3 is further equipped with a water treatment device, designated by the general reference 9, using a soluble or solution-resistant anti-scale agent, such as a complexing agent based on polyphosphates, intended to be added to water to delay scaling of the coffee maker.
- a soluble or solution-resistant anti-scale agent such as a complexing agent based on polyphosphates
- the complexing agent based on polyphosphates is preferably in solid form (crystal, granules), but can also be in powder or liquid form.
- the water treatment device 9 comprises a micro-dosing device 10 of a quantity of anti-scale agent which is determined as a function of the volume of water supplied to the water heater 6 and which is injected into water.
- the micro-dosing device 10 is preferably removably mounted inside the tank 1 by being arranged near the outlet 2 for emptying the tank, and is suitable for rapidly injecting a low dose of anti-scale agent in the water supplied to the water heater 6 ( Figure 2).
- the micro-dosing device 10 comprises a cartridge 12 of predetermined volume, for example of 30 cm 3 , which contains the anti-scale agent, for example a single polyphosphate crystal 14 of predetermined weight, for example 1.66 gram, and which has at its upper part a calibrated orifice 16 as well as a capillary tube
- the capillary tube 18 preferably has a cylindrical shape, of predetermined diameter, for example equal to 1.5 millimeters.
- the poured water enters the cartridge 12 through the orifice 16 and comes into contact with the polyphosphate crystal 14 which, by dissolution, generates a solution concentrated in phosphorus, identified at 23 in Figures 1 to 3; the capillary tube 18 is filled with this concentrated phosphorus solution at substantially the same level as the water level in the tank 1, see FIG. 1.
- the tank 1 begins to empty, and if the user decides to stop the emptying in progress of the tank, for example after a height of water emptied h ⁇ r as illustrated in the figure 2, which is equal to (Hh) where h is the height of water remaining in the tank from the zero reference level and varying from 0 to H, the level of the capillary tube 18 drops by the same height h x and the solution concentrated in phosphorus 23 is ejected at a low dose through the calibrated orifice 16 of the cartridge to be mixed there with the water supplied to the water heater 6, by the known phenomenon of pumping the water heater.
- the volume of concentrated phosphorus solution 23 which is added to the water supplied to the water heater during this emptying, FIG. 2, is proportional to the height of the emptied water h ⁇ .
- V volume (V) of concentrated phosphorus solution 23 which is added to 1 'water' during the emptying of the tank 1 is given by the expression:
- - H is the water height in the number of cups of coffee selected
- - h is the water height at filling and emptying of the tank, and varies from 0 to H.
- the zero reference level defined by the orifice 16 of the cartridge 12 is situated, relative to the bottom wall 4 of the reservoir 1, at a predetermined height h _, for example of the order of 10 millimeters, so as to take from the cartridge 12, when emptying the tank ( Figure 2), a perfectly homogeneous phosphorus solution.
- the cartridge 12 After complete emptying of the reservoir 1 of the coffee maker, as shown in FIG. 3, the cartridge 12 remains full of solution concentrated in phosphorus 23, the level of the capillary tube 18 balancing at the zero reference level.
- this micro-dosing device 10 advantageously constitutes a simple, economical, precise and particularly reliable device.
- it makes it possible to deliver or diffuse in water an amount of complexing agent based on polyphosphates which is perfectly controlled, moreover very low, which is independent of the solubility of the polyphosphate crystal 14, and which is proportional to a water height of the tank, therefore advantageously independent of the volume of water in the tank.
- this micro-dosing device 10 makes it possible, on the one hand, to maintain a concentration or level of phosphorus in water at a value of the order of 1 mg / 1 expressed as P 2 0 5 , thus respecting fully the legislation currently in force according to which the phosphorus concentration in the treated water, at the outlet of the spout of the coffee maker, must be lower than 5 mg / 1 expressed in P 2 0 5 , and on the other hand, to delay considerably in time the scaling of the water heater at least up to 500 liters of water.
- a very low concentration of phosphorus in the water supplied to the water heater of the coffee maker using this micro-metering device 10 makes it possible, surprisingly, to treat efficiently a very large number of liters of water without reaching the scale of the water heater, therefore significantly increasing the life of the coffee maker.
- Curve A has been noted for a coffee maker not equipped with a water treatment device and shows that scaling of the coffee maker is achieved for approximately 100 liters of water (point E).
- Curve B has been noted, for its part, for the same coffee maker, but equipped with a water treatment device according to the prior art, namely a perforated cartridge maintained above the maximum level of filling of the tank and containing a 1.66 gram weight polyphosphate crystal. This curve B shows that the scaling of the coffee maker is reached for approximately 200 liters of treated water (point F).
- curve C it was always taken for the same coffee maker, but equipped with the micro-dosing device 10, according to the invention, as described above.
- the volume of the cartridge 12 of the micro-dosing device 10 is chosen equal to 30 cm 3
- said cartridge 12 contains a single polyphosphate crystal 14 of weight equal to 1.66 grams
- the capillary tube 18 is cylindrical in shape, with a diameter equal to 1.5 millimeters. Thanks to this micro-dosing device allowing precise control of the amount of phosphorus added to the water supplied to the water heater of the coffee maker, curve C clearly shows that scaling of the water heater is not reached for 500 liters of treated water.
- the tests thus carried out showed the effectiveness of the micro-dosing device according to the invention, within a drip coffee maker, both in terms of the considerable delay in the scaling of the water heater of the coffee maker (by scaling to 500 liters of water), only in terms of maintaining the phosphorus concentration in water at a low value (of the order of 1 mg / 1 expressed as P 2 0 5 ) , and this by implementing a simple and reliable technology.
- the cartridge 12, FIG. 5, consists of a bottle 26 hermetically sealed by itself at its upper part 27 and filled, under a controlled atmosphere, with a liquid solution 29 of polyphosphates at a given concentration, and a cap 30 which is removably mounted, for example by screwing, on the bottle 26.
- the stopper 30 is provided at its upper part with the calibrated orifice 16 and with the capillary tube 18, and internally comprises a perforating member 32 intended to pierce the upper part 27 of the bottle 26 during the screwing the cap 30, so that the orifice 16 and the capillary tube 18 both open into the perforated part of the bottle 26 (see FIG. 6).
- the cartridge 12 thus produced is mounted inside the tank 1 of the coffee maker, as shown in FIG. 6.
- the liquid solution 29 contained in the sealed bottle 26 is advantageously homogeneous in phosphorus and perfectly aseptic.
