DETAILED DESCRIPTION OF THE DRAWINGS

(7) When referring to FIG. 1, we can see a cleaning apparatus according to the invention. It includes: an outer jacket 1, preferably made of a heat-insulating material, or provided to be associated with a layer of such heat-insulating material, a water tank 2, a metal block 3, arranged above the tank 2, capable of being heated by an electrical means for producing heat, in this case a resistor 30, one or several tubes 20, in this case two, which plunge into the tank 2, which pass through the metal block 3, in order to emerge at one end of the apparatus, not shown, in order to diffuse there the steam being produced, a base 10 to which the jacket 1 can be adapted in order to permit to reversibly connect the resistor 30 to an electric power supply 11.

(8) In practice, the resistor 30 brings the metal block 3 to temperature, then, when the required temperature is reached, for example 160°, which is controlled by suitable means, the apparatus can be separated from the base 10, in order to be capable to be brought to the place of use where a means, not shown, for pumping water is pushed into the tubes 20, until the portion thereof that passes through the metal block 3, where it is converted into steam, which is expelled under pressure out of the pipes 20 by a diffuser, not shown. This water can be pushed simply under the action of the pressure contained in its tank due to its preheating and through an opening valve placed between the tank and the heating body the metal block constitutes, which will finish the transformation of the water into steam. It should be noted that the pressure obtained in the water tank will be limited to the resistance to the pressure of the tank, but can easily be of about 1 bar, which will provide a greater autonomy. This valve device operating under pressure will permit the apparatus not to include any electrically operating element, a pump for example, and thus permits to omit the presence of a battery.

(9) The supply of the metal block with water from the tank can also occur by gravity and a valve for opening the tank in the case the tank would be placed above the metal block.

(10) The cleaning apparatus according to the invention thus permits to use the cleaning properties of steam, without the drawbacks of the wired apparatus currently used.

(11) Of course, the duration of steam generation is limited to the capability of the metal block to retain a sufficiently high temperature.

(12) When referring to FIG. 2, it can be seen, in a variant of the cleaning apparatus according to the invention, that the tank 2 includes a resistor 21 also likely to be connected to the base 10 in order to be electrically powered, and which permits to preheat the water contained in the tank 2, about 70° C. for example, or even more depending on the resistance provided to the construction of this tank 2 so as to increase the duration of use.

(13) Indeed, due to the storage of an already hot water, the calories stored in the block 3 are used only to raise the temperature of this water up to its vaporization.

(14) Referring now to FIG. 3, we can see another variant of the cleaning apparatus according to the invention, shown in a non-restrictive way with the previous variant, where the metal block 3 is provided with a resistor 4, powered by a battery 40 likely to be connected to the base 10 in order to be electrically recharged. This resistor 4 is aimed at being implemented after separation from the base 10, in order to maintain the heat of the block 3, such as to increase the duration of use. This battery 40 can also be associated with a remote power transmission apparatus, since this technique is applicable today.

(15) Referring now to FIG. 4, we can see another variant of the cleaning apparatus according to the invention, wherein the peripheral jacket 1 is comprised of two skins 12 and 13, which delimit a space 14 aimed at constituting the water tank.

(16) This configuration permits to preserve an inner space in which are placed the metal block 3 and the electric means for producing heat 30, which has several advantages, namely that the electrical means for producing heat 30 can be used to preheat the water contained between the two skins 12 and 13, and that this water and the two skins 12 and 13 created by an insulating wall permit to omit the use of a layer of insulating material.

(17) Furthermore, we can see that tubes 20 that traverse the metal block 3 do not follow a rectilinear path, but spiral through them. It should be noted that the tubes 20 can adopt many shapes, such as to increase the surface of exchange.

(18) It should also be noted that it is possible to integrate one or more resistors into the space 14, such as to carry out the preheating of the water.

(19) When referring now to FIGS. 5 and 6, we can see another variant of the cleaning apparatus according to the invention.

(20) In these figures, we see the outer jacket 1 made of a heat-insulating material, a water tank 2 arranged centrally and provided with a safety valve 22, a solid body 3 capable of storing calories and preferably consisting of a metal block, preferably aluminum, a resistor 30 that traverses the solid body 3, a tube 20 that passes through the solid body 3 and through which passes the water proceeding from the tank 2 in order to be transformed into steam.

(21) In this embodiment, the outer jacket 1 is, non-restrictively but preferably, of a general cylindrical shape, as well as the body 3 and the tank 2, which are concentric.

(22) The body 3 is arranged in two concentric tubular portions 31 and 32 delimiting a tubular space 33, in which is closely arranged a spiral structure 34, which can consist of a spiral spring, which creates, between the windings, a spiral passage 35 for the passing through of the water proceeding from the tank 2 through a valve 23, and which ends into the tube 20.

(23) On the other hand, the block 3 is traversed by an electric resistor 30 comprising two spiral segments 36 and 37, each associated with one of the concentric tubular portions 31 and 32, respectively, and united through a bridge 38, visible in 6, which passes through the tubular space 33.

(24) It should be noted that according to a variant not shown, the tank 2 can be arranged externally to the block 3.

(25) Generally speaking, the cleaning apparatus according to the invention can consist of a combination of several of the variants described above.

(26) Finally, for an easy use, the cleaning apparatus according to the invention can include a removable modular portion, which can comprise at least the tank and the metal block 3 its resistor 30.

(27) It is thus possible to be able to have several modules, permitting one of them to be prepared while another one is used.
