Description

Apparatus for treating fabrics comprising an instantaneous steam generator
Technical Field
The present invention relates to the field of devices for treating fabrics with steam, comprising an instantaneous vaporization steam generator comprising a vaporization passage and an injection opening in the vaporization passage, the vaporization passage comprising an end connected to a steam distribution circuit having a steam output hole to allow diffusion of the steam outside the device.
Background
From the application WO200227246 is known an iron comprising an instantaneous evaporation steam generator constituted by an evaporation passage of helical shape having a first end where water is injected by means of a pump and a second end connected to a steam distribution circuit to supply steam to steam output holes provided on the soleplate of the iron. In this document, the pump is controlled by a button located on the handle of the iron and when the user actuates the button, steam is produced on demand.
An advantage of an iron equipped with such an instantaneous steaming steam generator is that it is simpler and more economical than conventional irons equipped with a tank for generating steam under pressure, while also allowing a large supply of steam to be continuously produced.
However, a disadvantage of irons equipped with such a vaporisation passage is that steam can also be expelled from the holes of the soleplate for a few seconds after the pump has stopped, which is hardly noticeable by the user and can lead to burns in the latter. In fact, when the pump is stopped, part of the water previously injected by the high-pressure pump is quickly vaporized in the vaporization passage and a small portion of the water accumulates in the circuit without being quickly vaporized, so that the steam escapes only slowly through the steam outlet hole, since the steam present in the vaporization passage and in the distribution circuit is therefore no longer immediately driven outside the iron by the generation of a new steam flow.
Disclosure of Invention
The invention proposes, in particular, to overcome these drawbacks, a device equipped with an instantaneous vaporization steam generator in which the inertial phenomena of steam diffusion are reduced when the water injection is stopped.
The object of the invention is achieved by a household appliance, in particular for treating fabrics, the household appliance device comprises a steam generator comprising a vaporizing passage, means for heating the vaporization passage, and injection means for injecting water into the vaporization passage, the injection means comprising at least one injection opening to the vaporization passage, said evaporation passage comprising an end communicating with a vapour distribution circuit having at least one vapour output hole allowing said vapour to diffuse outside the device, characterized in that the vaporization passage comprises a blind portion (une partial bore) extending upstream of the injection opening, the blind part forms a dead passage (inpase) in which air is confined when water is injected into the vaporization passage through the injection opening.
Such a blind portion of the vaporization passage upstream of the water injection opening has the advantage of locking the air pocket which is trapped in the vaporization passage during steam generation, the latter occurring downstream of the water injection opening in the vaporization passage. Therefore, when steam is produced, the air trapped in the blind portion rises in pressure by the effect of heat, and when the injection of water into the vaporization passage is stopped, the steam present in the vaporization passage is quickly expelled out of the apparatus by the pressurized air stored upstream of the water injection opening.
According to another characteristic of the invention, the blind part of the vaporisation channel has a length greater than 5 cm.
This feature allows to obtain a large volume of air trapped in the blind part of the vaporisation passage and thus improves the effect of the pressure air to expel the vapour.
According to another characteristic of the invention, the vaporization passage extends over a total length greater than 50cm and advantageously has a spiral shape.
Such a feature allows to obtain a very good vaporization effect while maintaining a reduced volume.
According to another feature of the invention, the blind portion of the vaporisation passage occupies at least 10% of the total length of the vaporisation passage.
According to another characteristic of the invention, the passage section of the vaporization passage is less than 50mm2And preferably about 25mm2。
Such a feature allows reducing the volume of the vaporization passage and thus the time taken for the steam to leave the steam generator. Such a feature also allows for an increase in the speed of the steam flow in the steam generator. The waiting time between the moment of injection of water through the injection opening to the evaporation passage and the moment of exit of the steam through the steam outlet hole is therefore very short.
According to another characteristic of the invention, the passage section of the vaporization passage is substantially constant.
Such a feature allows to obtain a steam flow having a substantially constant velocity in the steam generator.
According to another characteristic of the invention, the injection means for injecting water into the evaporation circuit comprise a pump, advantageously an electric pump.
Such a feature allows to obtain a regular water supply to produce a steam flow continuously and substantially constant. The use of an electric pump also allows pressurized air to be injected into the vaporization passage for greater vapor supply.
According to another feature, the injection means comprise a flexible tube which enables a hydraulic connection between the pump and the injection opening, the wall thickness of the tube being adapted so that the passage section of the tube does not increase by more than 2% when it is subjected to the pressure of the liquid pumped by the pump.
Such a feature allows to avoid that, when the tube naturally contracts after being elastically deformed under the effect of the fluid pressure, a large increase in volume of water, for example greater than 0.5ml, is not injected into the vaporisation path when the pump is stopped.
According to another characteristic of the invention, the means for injecting water into the evaporation passage comprise a water reservoir.
According to another characteristic of the invention, the means for heating the vaporization passage comprise an electric resistance, the power of which is advantageously greater than 2000W and preferably about 2800W.
Such a feature allows for rapid heating of the vaporization passage and continuous steam supply of greater than 50 gr/min.
According to another characteristic of the invention, the vaporization passages are arranged in a heating body which encloses the electrical resistance, the heating body being advantageously made of an aluminum casting.
According to another feature of the invention, the resistance has a shape matching the path of the vaporization passage.
Such a feature allows the vaporization passages to be heated in a uniform manner for optimum performance.
According to another feature of the invention, the blind portion extends around the resistor.
Such a feature allows the air present in the blind to be heated more and thus allows the air to have a greater pressure.
According to another characteristic of the invention, the heating body is arranged in an iron and has a lower surface in thermal contact with a soleplate equipped with steam outlet holes, the evaporation passages being arranged on the upper surface of the heating body.
According to another feature of the invention, the device has a water reservoir carried by a base connected to the iron by a connecting cord.
Such a feature allows having a water reservoir that is remote from the iron, so that the iron is lighter and therefore easier to handle.
According to another characteristic of the invention, the device has a means for treating the water before it is injected into the steam generator to avoid the formation of scale, such as an ion resin exchange cartridge, or a means for injecting a scale inhibitor, such as a polyphosphate compound.

fig. 5 shows a top view of the heating body of fig. 4.
Detailed Description
Only the elements necessary for an understanding of the present invention are shown. To facilitate reading of the drawings, like elements are designated by like reference numerals throughout the various figures.
It is noted that in the present context, the terms "horizontal", "vertical", "lower", "upper", "front" and "rear" used to describe the iron refer to the device when it is laid flat on its ironing base plate.
Fig. 1 shows an iron 1, said iron 1 comprising a soleplate 2, said soleplate 2 being flat and being provided with steam outlet holes 20, a housing 10 made of plastic material being provided above said soleplate 2, said housing 10 comprising a gripping handle 11.
The iron 1 is connected to a base (not shown in the figures) by a connecting cord 3 in the form of a solenoid, the base enclosing a water reservoir and an electric pump, the operation of which is controlled by a pin 12, said pin 12 being provided on a grip handle 11 of the iron, the actuation of said pin 12 allowing the transport of water from the water reservoir through the connecting cord 3 in the direction of the iron 1 at a pressure of about 5 to 6 bar.
The connecting cord 3 is realized by a flexible tube, the thickness of the wall of which is adjusted so that the section of the passage of the tube does not increase by more than 2% when the tube is subjected to the pressure of the liquid pumped by the pump. As an example, the tube may be made of the material EPDM (ethylene-propylene-diene monomer) and have a thickness of 3mm for an inner diameter of 2 mm. In one variant, the tube made of EPDM can be reinforced with glass fibres or with an outer fabric.
According to fig. 2 to 5, the housing 10 encloses a heating body 4, the heating body 4 being in thermal contact with the base plate 2, the heating body 4 comprising an aluminum casting having a mass of approximately 300g and enclosing a shielded and isolated resistor 40 having a power of approximately 2800W.
Said resistance 40 advantageously extends according to a spiral form and has a first end 40A, which opens substantially horizontally to the rear of the heating body 4, and a second end 40B, which opens substantially vertically to the centre of the base plate 2, the supply of power to the resistance 40 being achieved, in a manner known per se, by a thermostat (not shown in the figures), which can be constituted by an electromechanical assembly or by an electronic thermostat of the NTC probe type associated with an electronic module, and which is fixed on the column 47.
The heating body 4 has a steam generator constituted by a vaporizing passage 41 in the form of a spiral, the upper part of this vaporizing passage 41 being closed by a closing plate 42 attached to the heating body 4, said closing plate 42 being equipped with an injection opening 43, at which injection opening 43 a connecting cord 3 is connected.
As shown in fig. 2 and 5, said vaporization passage 41 has a first end 41A, called open end, said first end 41A being advantageously located in the vicinity of the front end of the heating body 4, this open end 41A communicating with the vapor distribution circuit through a vapor output opening 45, said vapor output opening 45 being provided on the closing plate 42, as can be seen in fig. 3.
The steam distribution circuit ensures the diffusion of steam in the direction of the steam outlet holes 20 of the soleplate 2 and therefore has a connecting conduit 5, said connecting conduit 5 connecting an opening 45 with a conduit 44, said conduit 44 passing vertically through the heating body 4 to open into a steam diffusion chamber 46 arranged on the lower surface of the heating body, said steam diffusion chamber 46, in a manner known per se, supplying steam to the steam outlet holes 20 of said soleplate.
More specifically, according to the invention, the vaporization passage 41 has a closed end 41B through which the steam cannot escape, and the injection opening 43 opens into the vaporization passage 41 at an injection point a, which is remote from the closed end 41B.
The result is therefore that a portion of said vaporisation path 41, called blind portion 41C, is produced upstream of the injection opening a, illustrated by the corrugation in figure 5. This blind portion 41C is not open and forms a dead path in which an air bag is confined when water is injected into the vaporizing passage 41 through the injection opening 43, the air being pressurized by the pressure rise of the steam generated when the water is vaporized in the vaporizing passage 41 (due to the small passage section and the large length of the vaporizing passage 41).
The closed end 41B of the vaporization passage 41 is advantageously in close proximity to the electrical resistance 40, so that the blind portion 41C of the vaporization passage 41 is subjected to intense heating from the electrical resistance 40.
In the embodiment shown in the figures, the closed end 41B of the vaporisation passage 41 is located near the centre of the soleplate 2, at the base of the second end 40B of the electrical resistance 40, and the vaporisation passage 41 extends helically in three successive loops, which follow the contour of the soleplate 2.
Preferably, the length of the vaporisation passage 41 is greater than 50cm and the length of the blind portion 41C of the vaporisation passage 41 is at least 5cm, the passage section of the vaporisation passage 41 advantageously being less than 50mm2。
By way of example, the length of the vaporization passage 41 is approximately 90cm and the channel cross-section is 25mm2The channel cross-section advantageously has a square shape with a side length of 5 mm.
The operation of the device thus made will now be described.
At the start of the apparatus, the steam generator is cold and the thermostat controls the operation of the heating resistor 40, then an indicator light may be lit on the device to signal the user of the heating phase.
When the indicator light indicating the heating phase is off, the user can press the pin 12 of the iron 1 to cause the pump to operate and thus to inject water into the vaporisation passage 41 through the injection opening 43. The injected water is therefore immediately vaporized due to the thermal energy stored in the aluminium mass of the heating body 4. During this initial phase of steam production, the steam produced cannot escape towards the blind portion 41C of the vaporisation passage 41, since the vaporisation passage 41 is not open at the closed end 41B and due to the air present in the blind zone 41C.
Due to the small passage cross-section of the vaporizing passages 41, the generated steam thus momentarily escapes in the direction of the steam distribution circuit and then passes through the steam outlet holes 20 of the soleplate 2.
During the initial phase of heating before the water is injected, the air located in the blind portion 41C is heated and during the evaporation phase, it is compressed by the vapour of increased pressure in the evaporation passage 41. Thus, when the user releases the pin 12, the injection of water into the evaporation passages 41 is interrupted and the steam and the residual water present in the evaporation passages 41 are driven to the dry area and overheated by the evaporation passages 41 and then driven by the pressurized air present in the blind portion 41C to the direction of the steam output holes 20 of the soleplate, which allows to greatly reduce the inertial phenomenon of the steam when the pin 12 stops actuating, in other words, the iron tends to further diffuse the steam through the steam output holes 20 of the soleplate after the user stops actuating the pin 12.
An iron equipped with such a steam generator therefore has the advantage that the inertia of the steam is reduced when the pump is stopped, while also having a very good steaming effect, such an iron allowing to obtain a continuous steam supply of 50 g/min.
The invention is of course not limited to the embodiments described and illustrated, which are given as examples only. Variants are also possible, in particular from the point of view of the construction of the various elements or by substitution of technical equivalents, without going beyond the scope of protection of the invention.
In a variant embodiment, not shown, the vaporisation passage may therefore comprise a safety valve, advantageously carried by a closed cover and calibrated, for example, at 8 bar, to avoid the risk of excessive pressure in the vaporisation passage and damage to the iron, in particular in the event of excessive limescale (entry) in the steam distribution circuit.
Thus, in a variant embodiment, not shown, the iron may comprise a plurality of water injection openings distributed along the vaporization path to improve the ability of the steam generator to rapidly vaporize a large amount of water.
Thus, in a variant embodiment, not shown, the soleplate of the iron may comprise two separate vaporisation channels, one of which is designed to continuously produce steam at a supply rate of 50g/min and the other of which is designed to generate a steam pulse of 5 seconds at a flow rate of more than 70 g/min. As an example, these passages may have 9mm2And are square with a side length of 3mm and are each supplied with steam by a separate pump, these passages each advantageously having, upstream of the injection opening, a blind portion in which air is confined when water is injected into the evaporation passage. Preferably, the two vaporization passages are nested one within the other for greater compactness.
In another variant embodiment, not shown, the reservoir may therefore advantageously enclose a water treatment device that allows to avoid the formation of scale, such as an ion resin exchange cartridge or a device that ensures the diffusion of lime scale inhibitors, such as polyphosphates.
