The invention relates to a device for preparing a beverage by injection of water through a capsule containing a substance to be dissolved and/or to be extracted. The device comprises at least one water-injection system for introducing water inside the capsule. The injection system can be switched in order for a selection to be made between at least two different modes of wetting the substance so as to adapt wetting in accordance with the type of capsule and/or with the nature of the substance contained in the capsule. The invention aims to propose a device suitable for the preparation of a wider range of beverages, foaming or non-foaming, from substances to be extracted and/or soluble substances.

The invention claimed is: 1. A device for preparing a beverage by injecting water through a capsule containing a substance comprising at least one water-injection system for introducing water inside the capsule, wherein the water-injection system can be switched allowing for a selection to be made
The invention claimed is: 1. A device for preparing a beverage by injecting water through a capsule containing a substance comprising at least one water-injection system for introducing water inside the capsule, wherein the water-injection system can be switched allowing for a selection to be made between at least two different modes of wetting the substance so as to adapt wetting in accordance with the type of capsule and/or the nature of the substance contained in the capsule, wherein the water-injection system comprises at least one perforation and injection element that can be displaced in the capsule into at least two distinct positions with reference to a perforated surface of the capsule, wherein the perforation element can be displaced in accordance with two different depths in the capsule, and wherein the perforation element can be displaced into a first, upper position in the capsule in which at least one injection spike is uncovered in the capsule and a second, lower position in the capsule in which a greater number of injection spikes are uncovered in the capsule. 2. A device for preparing a beverage by injecting water through a capsule containing a substance comprising at least one water-injection system for introducing water inside the capsule, wherein the water-injection system can be switched allowing for a selection to be made between at least two different modes of wetting the substance so as to adapt wetting in accordance with the type of capsule and/or the nature of the substance contained in the capsule, wherein the water-injection system comprises at least one perforation and injection element that can be displaced in the capsule into at least two distince positions with reference to a perforated surface of the capsule, and wherein the water-injection system comprises at least a first perforation and injection element and at least a second perforation and injection element, distinct from the first perforation and injection element, which elements can be displaced relative to one another, each affording a different mode of wetting the substance in the capsule. 3. A device according to claim 2, wherein the first and second elements can be displaced in phase opposition relative to one another into at least a first position in which the first element is in engagement in the capsule and the second element is retracted from the capsule and, conversely, a second position in which the first element is retracted from the capsule and the second element is in engagement in the capsule. 4. A device according to claim 2, wherein the second injection element is a multi-spike plate for perforating, upon its engagement in the capsule, the surface of the capsule at multiple locations. 5. A device according to claim 2, wherein the second element is an injection spike located substantially in a center of the capsule and configured so as to produce multidirectional, divergent sprinkling in the form of at least one thin layer of water. 6. A device according to claim 2, wherein the first element comprises at least one injection point inside the capsule in the form of a jet configured so as to create, in the capsule, a swirling movement that mixes the liquid with the substance. 7. A device for preparing a beverage by injecting water through a capsule containing a substance comprising at least one water-injection system for introducing water inside the capsule, the water-injection system can be switched allowing for a selection to be made between at least two different modes of wetting the substance so as to adapt wetting in accordance with the type of capsule and/or the nature of the substance contained in the capsule, wherein the water-injection system comprises at least one perforation and injection element that can be displaced in the capsule into at least two distinct positions with reference to a perforated surface of the capsule, wherein an actuating means is provided for displacing at least said perforation and injection element selectively into the two positions by recognizing at least one of a size on a geometry of the capsule, and wherein the actuating means comprises at least one support integral with said perforation and injection element, which support can be displaced elastically relative to a head base, the actuating means comprising at least one detection means for moving the actuating means relative to the head base by complementary engagement of an edge of the capsule. 8. A device according to claim 7, wherein the injection system comprises a single, central injection spike integral with the actuating means so as to be positioned in a low position in the capsule when the detection means does not encounter a complementary edge of the capsule and an upper position in the capsule when the detection means encounters and engages a complementary edge of the capsule. 9. A device according to claim 8,wherein the central injection spike is configured so as to produce multidirectional, divergent sprinkling in the form of at least one thin layer of water. 10. A device according to claim 9, wherein the thin layer extends continuously over the periphery of the spike and sprinkles the substance in the capsule substantially circularly. 11. A device according to claim 9, wherein a number of discontinuous layers of water extend substantially distributed over the periphery of the spike. 12. A device according to claim 9, wherein the thin layer of water has a thickness of less than of equal to 0.5 mm. 13. A device according to claim 8, wherein the spike is configured so as to open due to water pressure against an elastic element, so as to free a passage having a thickness that is determined as a function of the pressure and thereby to create said layer of water. 14. A device according to claim 7, wherein the water-injection system comprises a first injection and perforation element in the form of an off-center injection spike integral with the actuating means and a second injection and perforation element in the form of a multi-spike plate connected to the actuating means by a rocker-type command means and is mounted so that it can be displaced relative to the head base, said multi-spike plate thus being moved into a position for perforation of the surface of the capsule when the detection means of the actuating means encounters and engages a complementary edge of the capsule and is moved into a position of retraction relative to the surface of the capsule, consequently allowing the entry of the injection spike into the capsule when the detection means does not encounter the complementary edge of the capsule. 15. A device according to claim 14, wherein the head base forms a hollow assembly for guiding the multi-spike plate and has sealing rims that close over a collector for receiving the capsule, the injection spike being in communication with said assembly in order to distribute the water in the hollow assembly through or substantially at the level of the multi-spike plate.
