An O-ring (56), located in the portion (57) internally seals the cover (14), when the closing cover (58) is embedded by means of clips (59) in the areas (60) of the cover (14), leaving the cover fixed and watertight. A closing cover (61) is embedded by clips (62) by means of the holes (63), leaving both the button (10) of the indicator (39) and the drinking button (11) fixed. Upper recesses (64) of the closing cover (61) help in holding the button (10) of the indicator (39) and the drinking button (11), by means of a surplus (65) thereof.

[0102] To prepare an infusion (27) of coffee, or another substance, an adequate amount of water (16) is introduced into the upper tank (8) without exceeding the area (54) thereof, pouring said quantity of water (16) inside the tank (1) through the upper area (55), the level being below the valve (3), the funnel (5) is inserted, with the bottom seal (4.1), upper seal (4.2) and with the seal (4), inside the water tank (1) (16), the coffee capsule (6) is embedded, in the seal (33) of the upper infusion tank (8), it is screwed the screw (9), of the infusion tank (8), on the thread (2) of the tank (1), sealing the invention, and then presses the button (10) of the indicator (39) of infusion level (27), and drinking button (11), fixing the surplus (65) with the upper recesses (64) of the closing cover (61) of cover (14), introducing the invention inside the microwave (38), applying medium heat or medium-high heat.

[0103] The water (16) from the tank (1) is heated, increasing the pressure, which drives part of the water (16) from the tank (1) upward through the lower inlet (28) of the funnel (5), the flow (16) entering the internal duct (29), directing the water (16), towards the needle (32), which distributes the water (16), inside the coffee capsule (6), by means of the needle (32), with perforations (50), until it comes into contact with coffee (37), or another substance, impregnating it and extracting the infusion (27), by means of the ring (6.2) by the upper portion (34) of the capsule (6), filtering the infusion (27) the filter (6.1) and leading it towards the outlet duct (35) of the upper tank (8), leading to the infusion (27), inside (15) of the Infusion tank (8), by means of end holes (12), the mast (66) of the float (40) reports the quality and quantity of infusion (27), by entering the infusion (27) through the inlet (67) located in the bottom of the spoon (14.2) obtaining in real time in the tank (8) the quantity and quality of infusion that is being generated.

[0104] Due to the effect of heat, and consequently, an increase in pressure and temperature inside the tank (1), a thermal shielding (1.1) is exhibited, which in the tank (1) and a thermal shielding (12) in the cover (14), allowing the extraction of the invention from the microwave, after a certain time interval, and drinking directly, from the button (11) of the cover (14) of the upper tank (8), the coffee infusion (27) by a solid-liquid-vapour extraction by microwave (38).

[0105] In the extraction phase, the infusion flow (27) produced inside the capsule (6) is filtered through the ring (6.2) through the upper portion (34) of the capsule (6), filtering the filter (6.1) the infusion (27) and leading it towards the outlet conduit (35) of the upper tank (8), leading to the infusion (27) inside (15) of the tank (8), through end holes (12).

[0106] In this way, it is avoided that the beverage fraction obtained by the solid-liquid-vapour extraction, is mixed with impurities in said process, also the thermal shields 1.1 and 12 and the shielding (1.2) of the tank (1) with the shielding (13) of the cover (14), protects the interior of the invention from electromagnetic waves (1.4) and high temperatures, obtaining an infusion of coffee, or another substance of first quality, allowing drinking from the same device.
