- the Venturi device 15 comprises a body 150 defining in its rear part an annular chamber 153 into which opens a nozzle 151 connected by a pipe 14 to the outlet 12 of the steam generator 103, to receive pure water vapor.
- a nozzle 152 also located at the rear of the Venturi 15 device allows the connection of the flexible pipe 16 for the supply of additive product and the application of this additive product to a central duct 155.
- a central part 156 comprising a part convergent for example frustoconical is arranged in the body 150 and allows the passage of steam from the annular chamber 153 in a converging annular space defined between the central part 156 and a external part of complementary shape 157.

- the cleaning device according to the invention has an efficiency increased compared to portable devices of the prior art, by the fact that it can, while remaining light, handy and inexpensive, produce instantaneous a significant flow of steam (for example 30 g of steam per minute), safely, regardless of the position of the device, and without scaling problems do not affect the operating capabilities of the device.
- An important aspect of the invention lies in the realization particularity of the steam generator 103 which, while being light, can provide a power greater than 1000 Watts.
- FIGS. 3, 4, 6, 7, the space 3 has been identified in which finds the capillary body for storing, in divided form, the water reserve to evaporate, without representing this capillary body, for the clarity of the drawing.
- the Figure 10 shows an example of implementation of capillary body 3 constituted, for example, by rock wool fibers resistant to high temperatures. The fibers of the capillary body 3 are compressed by the perforated box 6, 7 around the heater 20 and provide a role at a time for storage of water to evaporate and thermal insulation between the heating body 20 and the plastic elements such as the housing 6, 7 itself.
- the steam generator 103 constitutes a generator of instantaneous production of steam, working at atmospheric pressure and comprises a heating body 20 constituted by an armored resistor 2 overmolded in a metallic material which conducts heat well, such as of aluminum, to favor the heat dissipation of the resistance 2.
- the armored resistor 2 has the shape of a U with two straight branches 21, 22 and an elbow 23 for connecting the two rectilinear branches 21, 22.
- the body heater 20 has a plate 25 located in a mean plane defined by armored resistor 2 and having a V shape flaring outward at the free ends of the straight branches 21, 22 of the armored resistance 2.
- This plate 25 which promotes the diffusion of heat and forms a unit with the semi-cylindrical metal parts overmolded on the armored resistor 2, may include an appendage 24, located for example in the vicinity of the curved part 23 of the resistor 2, for positioning in the housing 6, 7.
- the heating body 20 comprises ribs 26 (FIG. 8) arranged in the vicinity of the elbow 23 of the resistor 2, between the rectilinear branches 21, 22 of the resistor 2, in a zone 4 near the elbow 23 which constitutes the zone of greatest power density, in which warms up most quickly in the event of drying of the body capillary 3.
- zone 4 is highly exposed to premature drying due to the downward flow of water by gravity, by the action of the vapor formed below this zone and rising towards the steam outlet 12 by taking water in transit or by heating the water of the capillary body 3 coating this part 4.
- the capillary body of storage 3 may include a first layer 131 of oriented fibers in a plane parallel to the plane defined by the armored resistance 2 and perpendicular to the two straight branches 21, 22 of this resistor armored 2 in the zone 4 near the elbow 23 of the resistor 2 and corresponding to the presence of the ribs 26 of FIG. 8. This contributes to limit drying by simply flowing water from top to bottom.
- the capillary body 3 advantageously comprises a second sheet 132 of fibers oriented perpendicular to the plane defined by the resistance 2, in areas close to the two straight branches 21, 22 and away from the elbow 23 of the armored resistance.
- the shape of the two half-housings 6, 7 is complementary to that of the heating body 20 surrounded by the capillary body 3. It can thus be seen that the case 6, 7 flares outwards on the side opposite the elbow 23, to hold account of the widening of the plate 25 in the form of V.
- an element of rectilinear thermal transmission 51 is connected to the heater 20 vicinity of the internal part of the elbow 23 of the resistor 2, and ends by an end provided with a housing 53 in which a sensor is disposed thermal 55, which has been shown in Figure 7 but has been omitted in Figure 4 and FIG. 8.
- the thermal sensor has two pins 59 for connection for connection to regulating elements of the power supply resistance 2, which can be arranged in a separate compartment 104 adjacent to the sealed enclosure 10 of the steam generator 103.
- An elbow heat transfer element 52 is connected to the heating body 20 in the vicinity of the external part of the elbow 23 of the shielded resistor 2 and ends, outside the sealed enclosure 10, by one end provided with a housing 54 in which a sensor is disposed thermal 56, provided with two connection pins 58 for connection to elements for regulating the supply of resistor 2, placed in compartment 104, into which the power cord opens cleaning appliance (not shown in the drawings).
- the thermal sensor 56 has not been shown in FIG. 8.
- the thermal transmission elements 51, 52 constitute appendages which arise closest to the elbow 23 and may be produced by overmolding in the same material as the plate 25, as for example aluminum.
- the thermal sensors 55 and 56 such as thermostats, have different setpoints for better regulate the supply of the heating resistor 2 whose temperature increases rapidly as soon as the capillary body dries up in the zone 4 adjacent to the elbow 23.
- At least the rectilinear thermal transmission element 51, and the if necessary also the angled thermal transmission element 52 is advantageously thermally insulated by an external sheath made of a material thermally insulating, such as silicone, to avoid cooling by water not evaporated in the lower part possibly contained in the body capillary surrounding this thermal transmission element 51.
- the rectilinear branches 21, 22 of the resistor 2 pass through the wall of the enclosure 10 in a sealed manner using seals such as the seal 84, illustrated in Figure 7, in a material such as vitton or silicone.
- the compartment cover 104 can be ultrasonically welded to enclosure 10, once assembly is complete.
- the thermal sensors 55, 56 can be constituted by for example by thermostats, thermal probes, limiters or fuses.
- thermal sensors 55, 56 and elements of thermal transmission 51, 52 associated with a simple regulation circuit supply allows to implement a shielded resistance 2 in U of current type and of a power for example of 1200 Watts, without it an excessive risk of overheating ensues, even if in operation a part of the capillary body 3 dries up.
- the whole of the waterproof enclosure 10 and of the separate compartment 104 which constitutes the steam generator 103 is removable and allows easy replacement. Electrical connections within compartment 104 are well separated from the enclosure 10 where the water is stored in the body capillary 3 compressed by the perforated housing 6, 7 around the heater 20.
- Tap water is introduced by the input 13 which with the channel 13A is integral with the enclosure 10. Water permeates the capillary body 3 disposed in the perforated housing 6, 7 and excess water can be discharged through the inlet 13 by returning and shaking the device. After closing the plug 13B and connecting the electrical cord, the appliance is ready to operate.
- the regulation of resistor 2 can be supplied automatically so safe without operator intervention, thanks to the measures explained more high. After pressing the on-off button allowing regulated power supply of resistor 2 and therefore the production of steam, the operator simply has to decide whether or not to press the trigger 32, whether or not he wishes to have a mixture of steam and the product optional additive desired placed in tank 19 which may be transparent to check its contents and removable to facilitate its replacement.
- the user can at any time cut off the emission of steam by interrupting the electrical supply to resistor 2 using the button On Off.
