FR 3 053 444 - A1 (54 / WIRELESS STEAM PRODUCTION APPARATUS

©) Wireless steam generating device comprising a water tank, means (32) for extracting the steam produced by steam generating means, which comprise means (1) for storing previously generated calories to said cleaning operation, by electrical means for producing heat reversibly connectable to an electrical supply, and where the storage means (1) consists of a metallic mass.

The steam generation means are in the form of a cavity (3) formed in the metallic mass (1), interposed between on the one hand means (20; 30) for conveying the water coming from the tank and on the other hand the steam extraction means (32), the cavity (3) comprising at least one receiving wall (31) on which the water is projected through projection means associated with the means for routing (30).

i

The present invention relates to a wireless apparatus for producing steam.

The present invention relates in particular, but not limited to the field of cleaning by spraying of vapor.

We already know, from document WO 2014/009666 in the name of the present applicant, a wireless cleaning device, comprising a solid metal body, designed capable of storing calories, and crossed by at least one channel or the like which connects a water tank to vapor extraction means.

The object of the present invention is to improve the aforementioned device, so as to increase its efficiency, in particular to allow the diffusion of a vapor of practically constant temperature throughout its use.

The wireless steam generating device according to the invention comprises a water tank, means for extracting the steam produced by steam generating means, which comprise means for storing calories generated, prior to said cleaning operation, by electrical means for producing heat reversibly connectable to an electrical supply, and where said storage means consists of a metallic mass, characterized in that said steam generation means are in the form of a cavity formed in said metallic mass, interposed between on the one hand means for conveying water coming from said tank and on the other hand said means for extracting steam, said cavity comprising at least one receiving wall on which water is sprayed through projection means associated with said conveying means.

Getting a constant temperature vapor remains complex. In the case of a wireless generator, the metal mass, which constitutes the reserve of calories, is heated to the highest possible temperature in order to be able to conserve calories as long as possible. However, if the steam remains in the chamber for a long time, it will reach a temperature too high to be usable.

It is therefore necessary to control the quantity of vapor created, as well as its rapid extraction.

This is achieved in the present invention, because the area of the bottom of the chamber on which the water is projected is large in proportion to the water flow.

According to an additional characteristic of the device according to the invention, the cavity is formed inside the metallic mass and is in the form of a chamber.

According to another additional characteristic of the device according to the invention, the cavity is formed at the periphery of the metallic mass and is hermetically closed by a cover.

According to another additional characteristic of the apparatus according to the invention, the means for projecting water are configured to project it into fine droplets on the receiving wall.

According to another additional characteristic of the apparatus according to the invention, the wall or walls on which water is projected, has roughness.

Asperities have the function of slowing the movement of water droplets entrained by the flow of steam.

According to another additional characteristic of the apparatus according to the invention, the roughness is in the form of a multiplicity of alternately concave and / or convex zones.

According to another additional characteristic of the apparatus according to the invention, the means for extracting the vapor are associated with a filter to be demistered.

It is possible that the quantity of water is not completely controllable depending for example on the shapes of the device, also, the use of a filter to be deveiculated, placed at the level of the steam outlet, allows to retain a possible excess of water by capillary action of the water.

According to another additional characteristic of the device according to the invention, the filter to be de-dewedding consists of iron or stainless steel straw.

The advantages and characteristics of the apparatus according to the invention will emerge more clearly from the description which follows and which relates to the appended drawing, which represents several non-limiting embodiments.

In the attached drawing:

- Figure 1 shows a schematic sectional view of the steam generator of an apparatus according to the invention.

- Figure 2 shows a schematic sectional view of another embodiment of the steam generator of an apparatus according to the invention.

- Figure 3 shows a partial schematic perspective view of a steam generator of an apparatus according to the invention.

FIG. 4 represents a schematic sectional view of the steam generator of FIG. 3.

With reference to FIG. 1, it can be seen that a steam generator of a wireless cleaning device according to the invention comprises, in a similar manner to document WO 2014/009666, a solid metallic body 1, designed capable of store calories, within which is formed a chamber 2, connected on one side to a pipe 20 for supplying water and on the opposite side to a pipe 21 for extracting steam.

Between the two mouths of the conduits 20 and 21 extends the bottom 22 of the chamber 2.

In operation, water is sprayed through line 20 onto the bottom 22 kept warm, in contact with which water is vaporized to escape under pressure through line 21.

With reference to FIG. 2, one can see, according to another embodiment, a solid metallic body 1 at the periphery of which is formed a chamber 3, open to the outside, and into which a water supply conduit 30 opens. , while a cover 4 closes the chamber 3, said cover comprising a duct 40 for extracting steam.

As for the embodiment of FIG. 1, the water is sprayed through the pipe 30 onto the bottom 31 of the chamber 3, in contact with which it is vaporized to exit under pressure through the pipe 40.

With reference to FIGS. 3 and 4, one can see a part of a steam generator, and more particularly the solid metallic body 1, at the periphery of which is formed a chamber 3, open on the outside, intended to be hermetically sealed by a cover 4 not shown in FIG. 3, and into which opens on the one hand a water supply duct 30, and on the other hand a steam extraction duct 32, not visible in FIG. 4.

The bottom 31 of the chamber 3 comprises a multiplicity of convex asperities 33 which, as shown in FIGS. 4 and 5, can also be concave, knowing that it is also possible that the bottom 31 has concave asperities and asperities convex.
