DESCRIPTION:
BRIEF SUMMARY
The invention concerns an infusion machine having an infusion collection receptacle delimited by a lateral wall and a base wall and capable of being placed beneath the outlet orifice of a filter of an infusion machine, such as a coffee maker of the drip type, for example. The said collection receptacle generally rests on a base of the said infusion machine.
The infusion collection receptacle comprises a handle fixed to the said lateral wall by attachment means, a spout through which the infusion is poured out of the receptacle and a lid with an opening through which the infusion flows into the receptacle.
The lid of an infusion collection receptacle of a known type has a central opening capable of being placed beneath the outlet orifice of the filter, through which the infusion may drip. Such a receptacle with several openings, namely the spout and the said central opening, allows a significant amount of air to circulate, which is detrimental to the obtaining of a good infusion aroma and leads to heat losses which change the nature of the infusion obtained.
The aim of the invention is to remedy the aforementioned drawbacks by using an infusion machine having an infusion collection receptacle which thus preserves most of the characteristics of the infusion that it contains.
According to the invention, the opening is situated opposite the spout and the outlet orifice of the filter is arranged so as to hang over the said spout in an infusion position.
According to another characteristic of the invention, the infusion collection receptacle has a grille positioned close to the spout, designed to close off the opening situated opposite the spout at the end of the infusion process.
By means of such an infusion collection receptacle, most of the aroma of the infusion is preserved within the receptacle without the use of a sealing joint. Moreover, the reduction in the number of openings at the upper periphery of the infusion collection receptacle limits heat losses, thereby improving the temperature of the infusion.
Furthermore, owing to the airtightness of the receptacle, air does not filter into the inside of the receptacle, and no oxidation of the infusion is therefore produced, and the steam formed within the receptacle does not escape, thereby preventing any caramelization of the infusion.
The characteristics and advantages of the invention will, moreover, emerge from the following description, taken as a non-limitative example, with reference to the accompanying drawings in which:
FIG. 1 is a schematic view of an infusion machine in which an infusion collection receptacle according to the invention is positioned,
FIG. 2 is a vertical section, to a larger scale, of the infusion collection receptacle of FIG. 1.
According to FIG. 1, an infusion machine 7, such as a coffee maker of the drip type, for example, comprises, inside a casing 6, a cold-water reservoir 16 and a water heater 17 supplied by this reservoir 16 and itself supplying, via an ascending hot-water tube 18, a spray nozzle 19 designed to spray a removable filter 5 known per se, fitted inside the said casing 6 and designed to receive ground coffee.
The filter 5 has an outlet orifice 4 beneath which is placed an infusion collection receptacle 1 resting on a base 8 of the said infusion machine 7.
The infusion collection receptacle 1 is delimited by a lateral wall 2 and a base wall 3. The said receptacle 1 comprises a handle 9 fixed to the lateral wall 2 by attachment means, a spout 10 through which the infusion can be poured out of the receptacle 1 and a lid 11 with an opening 12 through which the infusion flows into the said collection receptacle 1.
In our example embodiment, the lid 11 is fixed to the handle 9.
According to the invention, the opening 12 is situated opposite the spout 10 and the outlet orifice 4 of the filter 5 is arranged so as to hang over the said spout 10 in an infusion position.
The infusion collection receptacle 1 has a locating means 13 suitable for positioning the spout 10 opposite the outlet orifice 4 of the filter 5 in the i
