Definitions
- the present invention relates to filters intended to equip boiling water containers, in particular kettles and arranged in the filling orifice of said containers.
- Such filters have, for example, been described in French patent application FR-2 712 474. These filters include a demineralization material such as an ion exchange resin and are well suited to retain lime. On the other hand, it can be seen that in the presence of running water containing organic matter in suspension, pesticides, chlorine, etc. and having a high hardness, there occurs, after boiling, a transformation of the water aimed at greatly degrading its optical quality, or even causing the user a certain aversion to using this boiled water to prepare tea infusions or of coffee.
- a demineralization material such as an ion exchange resin
- the invention therefore aims to provide a filter which eliminates the drawbacks set out above.
- the filter comprises a sheet of activated carbon.
- the filter is arranged in a boiling vessel, the wall of which is made of a plastic material, preferably polypropylene.
- the clarification problems amplified by the degradation or diffusion of the components of the plastic material are solved and one notes an attenuation of this degradation which contributes to obtaining water of very satisfactory optical quality.
- FIG. 1 shows a filter according to the invention fitted to an electric kettle
- FIG. 2 is a graph illustrating measurements of the percentage of light transmitted by untreated water and by water treated by a filter according to the invention
- FIG. 3 shows another embodiment of a kettle equipped with a filter according to the invention.
- the container 1 for boiling water represented in FIG. 1 is, for example, a kettle comprising a body 2, the bottom 3 of which carries a heating means such as, for example, an immersed resistance 4, and the filling orifice 5 is equipped with a support 6 in which a filter 7 is arranged.
- the immersed resistance 4 is of the tubular type with chromium coating and has for example a power of 2200 Watts under a voltage of 240 V thus allowing very quickly to bring 1.5 liters of water to a boil.
- the support 6 is integral with a flange 8 forming a partial cover of the orifice 5 to provide a pouring spout 9.
- the support 6 has the general shape of a basin whose the bottom 10 is perforated and is located at a distance from the maximum level N of liquid authorized for filling. Thus the filter 7 is always kept above this maximum level N.
- This level is shown in broken lines in FIG. 1 and is generally indicated to the user by a marking (not shown) produced on the internal wall of the body 2.
- the filter 7 comprises a sheet 11 of activated carbon.
- this activated carbon is treated with silver.
- the sheet 11 is enclosed in a bag 12 of filter material, for example, of a so-called non-woven material. Thanks to this arrangement, the bag 12 is removable and easily changeable.
- the sheet 11 of activated carbon has a thickness close to 10 mm for a height corresponding to approximately 20 grams of this activated carbon.
- Activated carbon is, for example, either in the form of granules or in the form of a nonwoven mattress impregnated with activated carbon.
- the body 2 of the container 1 is made of a plastic material, of preferably polypropylene of the type having the properties of being in particular heat resistant, not loaded with talc, antistatic and food.
- the polypropylene used for the tests illustrated in FIG. 2 is a HOSTALEN PPU 4080 ASTL from the company HOECHST.
- the water used to carry out the tests has a hardness close to 40 TH.
- Curve A represents the measurement of the visual appearance of boiled water from a kettle not equipped with a filter
- curve B is that of water boiled in a kettle, made of polypropylene and equipped with a filter according to the invention.
- the value of the light transmission according to curve A remains substantially between 80% T and 87% T from 10 liters to 30 liters and therefore has a cloudy appearance.
- curve B after passing cold water through the filter 7, it can be seen, on curve B, that the optical quality of the water remains higher than that according to curve A, and can on average be considered as crystalline water.
- the container 15 comprises a body 16 made of a plastic material such as polypropylene, preferably a HOSTALEN PPU 4080 ASTL from the company HOECHST, of which the bottom 17 carries a heating means 18 and which has a filling orifice 19 fitted with a filter 20, as well as a cover 21 partially closing said orifice and providing a pouring spout 22.
- a plastic material such as polypropylene, preferably a HOSTALEN PPU 4080 ASTL from the company HOECHST, of which the bottom 17 carries a heating means 18 and which has a filling orifice 19 fitted with a filter 20, as well as a cover 21 partially closing said orifice and providing a pouring spout 22.
- the filter 20 comprises a sheet 23 of activated carbon enclosed in a bag 24 of filtering material thus constituting a removable cartridge and maintained by a support 25 above the maximum level (N) authorized during the filling of the container and materialized in lines interrupted, this level being indicated by a marking 26 produced on the internal wall of the body 16.
- the support 25 is formed in the cover 21, presently made in one piece with this cover, and has the shape of a basin whose bottom 27 has a restricted opening 28 for flow.
- this restricted opening 28 in the present case a circular hole of approximately 1.5 cm in diameter relative to the circular bottom 27 of diameter 8 cm, the reliability of the sheet 23 of activated carbon is guaranteed (treated or not with silver) by minimizing the passage of hot water vapor to said sheet 23 and thus promoting the escape of this vapor by the pouring spout 22.
- the bottom 27 In order to satisfy the conditions for a good flow of cold water through the filter 20 and prevention of penetration of the steam into the support 25, provision is also made for the bottom 27 to have a series of ribs 29 on which the bag 24 of the filter 20 rests and which also extend above the restricted opening 28, thus providing a space between said bag and said bottom of the basin.
- the support 25 in the form of a basin is equipped with a cover 30 mounted articulated at 31 on the cover 21.
