Description

Technical Field

[0001] This invention relates to the field of small household appliances, and more specifically to ironing devices. Background Technology

[0002] Irons are typically used to iron clothes. However, due to limitations of irons (e.g., the need for an ironing board), portable ironing devices have been developed that eliminate the need for an ironing board and offer greater convenience and speed of use. These devices are often called "steam irons" or "steam irons." When clothes are hung on hangers, the ironing device irons them by applying heat to the ironing surface, combined with the release of steam. Ironing devices allow for the ironing of clothes under proper conditions.

[0003] In practice, it has been observed that users do not stretch the garments sufficiently and do not press the ironing surface firmly enough, thus limiting the device's operation. Consequently, garments are not ironed as well as when the device is used correctly. Therefore, ironing devices that suck up the garments in addition to heating and releasing steam have been proposed. These improved devices require a motor to achieve the suction, which may overheat. Summary of the Invention

[0036] It should be noted that in this article, the terms “vertical,” “down,” “up,” “front,” and “back” used to describe the ironing device refer to the device when it is laid flat on its base.

[0037] Figure 1 An ironing device 1 with a portable housing 10 is shown. The portable housing includes a handle 4, on which an ironing head 2 is provided. The ironing head includes a processing surface 20 facing the fabric sheet to be ironed. The side of the portable housing 10 with the processing surface 20 corresponds to the front of the portable housing 10.

[0038] The ironing device is characterized in that it also includes a base 6 in the extension of the handle 4 on the opposite side of the ironing head 2.

[0039] See Figure 2 and Figure 3 The portable housing 10 also includes an air suction circuit comprising a fan 21 driven to rotate by a motor 23, and including at least one air suction outlet 201. The fan 21 and the motor 23 are preferably arranged in the ironing head 2.

[0040] The portable housing 10 also includes a steam circuit with a steam generator 61. This steam generator 61 is preferably arranged in the base 6.

[0041] The steam circuit is adapted to allow steam to be discharged at the processing surface 20, and the air suction circuit is adapted to allow air to be drawn from the processing surface 20.

[0042] Preferably, the portable casing is made of a plastic material. For example, the portable casing can be made of polypropylene or polycarbonate.

[0043] As the name suggests, the casing is portable. Therefore, it is designed to be carried by an individual, and the device is designed to be operated with one hand, specifically by being held by the handle 4.

[0044] The portable housing 10 preferably includes control devices 8 (e.g., in the form of buttons) configured to control steam discharge and air suction. The control devices 8 are preferably located on the handle 4. These control devices 8 are preferably designed to be actuated by the user's hand using the portable housing carrying the ironing device.

[0045] In addition, handle 4 is designed to accommodate cables, for example, for powering motor 23.

[0046] The handle 4 preferably has a weight of about 50 grams.

[0047] The base 6 includes a flat outer surface 60, which is designed to be in Figure 4 In the so-called resting position shown, the device is placed on a substantially flat surface S. This surface 60 is preferably the distal surface of the base 6.

[0048] When device 1 is in its rest position, the longitudinal axis P of handle 4 (as shown) Figure 4 (As shown) Preferably slightly tilted forward. Specifically, the portable housing 10 is configured such that the longitudinal axis P forms a non-zero angle with the axis perpendicular to the outer surface 60 (corresponding to the parking surface S of the device), for example, an angle of about 15°.

[0049] According to another embodiment, the longitudinal axis P of the handle 4 is perpendicular to the outer surface 60.

[0050] Preferably, the base 6 has a rear surface equipped with a button that allows the device to be powered on.

[0051] Preferably, the base 6 also includes a power cord that allows it to be connected to the household power grid. The power cord may be detachable.

[0052] The length of the power cord is preferably greater than 200cm. When the user carries the device 1 to a height of about 1.5 meters above the ground, the weight of the power cord is preferably about 150 grams.

[0053] According to an embodiment not shown, the ironing device 1 does not include the base 6. Therefore, the power button can be arranged, for example, on the portable housing 10, more precisely on the ironing head 2. Similarly, a power cord can be connected to the portable housing 10, more precisely to the ironing head 2.

[0054] The ironing device 1 preferably includes a steam generator 61 forming part of a steam circuit. The steam generator 61 is adapted to generate steam from liquid from a reservoir 62. The steam generator 61 defines a cavity for receiving liquid, and preferably includes at least one shielded heating element 65 that allows heating of the liquid from the reservoir 62 within the cavity. The steam generator 61 is preferably connected to a conduit 41 of the steam circuit, the conduit being arranged to allow steam to flow from the steam generator 61 to the ironing head 2.

[0055] The steam generator 61 is typically made of a metal body, such as aluminum, and preferably has a mass of about 250 grams. This mass typically includes the mass of the aluminum structure, the shielded heating element 65, the electrical safety and thermal regulation elements, and the mass of the concentrator preferably included in the steam generator 61.

[0056] The reservoir 62 is preferably included in the portable housing 10 and arranged in the base 6. According to an embodiment not shown, the reservoir 62 is removable.

[0057] according to Figure 2 In the illustrated embodiment, the reservoir 62 is arranged in the front of the portable housing 10, or more specifically in the front of the base 6.

[0058] The reservoir 62 preferably includes a transparent sleeve defining the outer wall of the reservoir 62, the transparent sleeve being equipped with a removable plug 620 that allows filling of the reservoir 62. The reservoir 62 is adapted to contain a liquid, typically water or a liquid solution diluted in water.

[0059] The reservoir 62 preferably has a capacity of about 100 mL. When empty, the reservoir preferably has a mass of about 50 grams. For example, when the reservoir 62 contains about 100 grams of water and is therefore 100% filled, it has a mass of about 150 grams.

[0060] Also preferably, the steam circuit includes a pump 63 arranged to allow liquid to flow from the reservoir 62 to the steam generator 61, and the pump 63 is advantageously arranged in the base 6.

[0061] Pump 63 preferably has a mass of about 50 grams.

[0062] according to Figure 2 In one possible implementation shown, the steam generator 61, the liquid reservoir 62, and the pump 63 are included in the portable housing 10, or more precisely, in the base 6.

[0063] According to another embodiment not shown, the steam generator 61, the reservoir 62, and the pump 63 are not included in the portable housing 10, but are instead included in a base offset relative to the portable housing 10. This base is preferably connected to the portable housing 10 via a flexible conduit that allows steam to flow from the steam generator 61 to the ironing head 2.

[0064] The ironing head 2 is connected to the upper end of the handle 4, and the base 6 is connected to the lower end of the handle 4 opposite to the upper end. According to... Figure 1 In the embodiment shown, the lower part of the handle 4 has a flared shape, and its cross-section gradually increases as it approaches the base 6.

[0065] The ironing head 2 includes a front end equipped with a treatment surface 20 facing the fabric sheet to be ironed. The ironing head 2 also preferably has a rear end opposite the front end and is equipped with a rear surface opposite the treatment surface 20. Furthermore, the ironing head 2 preferably has a side surface extending between the rear surface and the treatment surface 20.

[0066] The processing surface 20 preferably includes a processing plate 200, which is preferably metallic, such as an aluminum processing plate 200.

[0067] The processing plate 200 may be, for example, a heated plate 200 for improving ironing, as described below. Such a heated plate 200 may be heated by one or more heating elements 26 arranged in an ironing head near the processing surface 20.

[0068] The processing surface 20 includes at least one steam outlet hole 24 connected to the steam circuit and at least one suction hole 22 connected to the air suction circuit.

[0069] The processing surface 20 can have different shapes, such as rectangular or triangular. Preferably, it includes multiple steam outlet holes 24 and multiple suction holes 22.

[0070] Different steam outlet holes and suction holes can be in the form of holes or slits. Figure 1 In the example shown, the steam outlet hole 24 is in the form of a hole, and the suction hole 22 is in the form of a slit.

[0071] Advantageously, a secondary steam generator 25 is arranged within the ironing head 2. The secondary steam generator 25 forms part of the steam circuit. The secondary steam generator 25 is preferably connected to the conduit 41. In fact, the secondary steam generator 25 allows the re-evaporation of liquid from the steam generator 61 (referred to as the "primary steam generator"), which has already flowed in the conduit 41. Indeed, as steam flows in the conduit 41, it can be cooled to the point of partial condensation. Therefore, the steam condensate flows to the secondary steam generator 25. The secondary steam generator 25 preferably allows the evaporation of these condensates so that no liquid is discharged through the steam outlet hole 24. It is particularly advantageous to avoid liquid discharge through the steam outlet hole 24, as this would wet the treated fabric sheet and prevent it from being properly ironed. For evaporating the condensate, the secondary steam generator 25 preferably includes at least one PTC thermistor type heating element 26 or a shielded heating element. The secondary steam generator 25 can also be referred to as an "evaporator" because it allows the reheating of the steam already generated by the steam generator 61.

[0072] Preferably, the heating element 26 of the secondary steam generator 25 is in thermal contact with the processing surface 20. Therefore, the processing surface 20, preferably more precisely the heating plate 200, can be heated by one or more heating elements 26 of the secondary steam generator 25, which allows for more efficient ironing when the processing surface 20 is arranged facing the fabric sheet.

[0073] According to an embodiment not shown, the silicone component is placed between the heating element 26 and the processing surface 20 of the secondary steam generator 25, such that the temperature of the processing surface 20 does not exceed a certain temperature threshold, typically 150°C.

[0074] The secondary steam generator 25 is typically made of a metal body, such as aluminum.

[0075] The secondary steam generator 25 also preferably includes electrical safety and thermal regulation elements.

[0076] Therefore, the assembly including the processing surface 20 and the secondary steam generator 25 preferably has a mass of about 100 grams.

[0077] The ironing head 2 includes an air suction circuit extending between a suction port 22 and a suction air outlet port 201. The suction air in the air suction circuit flows in... Figure 5 The solid arrows indicate this. The air suction circuit also includes a fan 21 and a motor 23. The fan 21 and motor 23 are arranged in the ironing head 2.

[0078] Preferably, the motor 23 is arranged inside the ironing head 2 in the axial extension of the processing surface 20. The motor 23 moves along... Figure 4The longitudinal axis M shown extends as follows.

[0079] like Figure 4 As shown, the ironing head 2 has an elongated shape extending transversely to the handle 4, preferably forming an angle α of approximately 65° with respect to the longitudinal axis P of the handle. Preferably, the handle 4 extends along an axis passing through at least a portion of the motor 23. The axes P and M advantageously intersect.

[0080] Motor 23 is adapted to drive fan 21 to rotate. Fan 21, which forms part of the air suction circuit, allows air to be drawn from air suction port 22.

[0081] The assembly including motor 23 and fan 21 preferably has a mass of about 300 grams.

[0082] Preferably, the air suction circuit is configured to allow a range greater than 10m. 3 / h and less than 60m 3 An air suction flow rate of / h is preferred, and more preferably greater than 20m / h. 3 / h and less than 50m 3 Air suction flow rate of / h.

[0083] The air suction outlet 201 is preferably located on the rear surface. "Rear surface" should be understood as the air suction outlet 201 being located on the rear surface or on a side surface close to the rear surface. If the air suction outlet 201 is located on a side surface, it is preferably located at a distance of less than 9 cm from the rear surface.

[0084] The ironing head 2 includes an air cooling circuit for the motor 23, extending between at least one cooling air inlet hole 203 and at least one cooling air outlet hole 202 disposed in the ironing head 2. Cooling air flows in the cooling circuit... Figure 5 The dashed arrows indicate this. The air cooling circuit for motor 23 is designed to allow for the cooling of motor 23, which generates heat during operation. If motor 23 reaches a certain critical temperature threshold, it may fail, and therefore cooling is desirable. Preferably, the ironing head 2 includes at least two main cooling air inlet holes 203 and at least two cooling air outlet holes 202.

[0085] like Figure 5 As shown, the cooling circuit and the air suction circuit are separate and distinct. This advantageous arrangement allows the motor 23 to be effectively cooled while preventing any damage to the motor caused by the flow of steam-containing air within it.

[0086] like Figure 5As shown, the cooling air inlet hole 203 is preferably arranged on the side surface of the ironing head 2. It is also preferred that the cooling air outlet hole 202 is arranged on the rear surface. If the cooling air outlet hole 202 is arranged on the side surface, it is preferably arranged at a distance of less than 8 cm from the rear surface. It is also preferred that it is arranged at a distance of more than 1 cm from the rear surface.

[0087] According to an embodiment not shown, the cooling air outlet 202 of the cooling circuit leads into the air suction circuit at the suction air outlet 201 of the air suction circuit. "At the suction air outlet" should be understood as the cooling air outlet 202 being located near the suction air outlet 201, for example, at a distance of less than 2 cm. This allows for the generation of the Venturi effect and increases the flow velocity of the suction air and cooling air (thus optimizing cooling within the device).

[0088] Advantages, such as Figure 3 As shown, the cooling circuit also includes a rotatably mounted propeller 27 to direct air entering through the cooling air inlet port 203 toward the cooling air outlet port 202. The propeller 27 allows air to flow along... Figure 5 The path indicated by the dashed arrow guides the air. Propeller 27 can be axial, helical-centrifugal, or centrifugal.

[0089] The propeller 27 can be arranged in different positions relative to the motor 23. The motor 23 extends longitudinally along its axis from a first end to a second end. The first end is closer to the processing surface 20 than the second end. The propeller 27 can be arranged, for example, at either the first or second end of the motor 23, in other words, in front of or behind the motor. However, it is preferred that the propeller be located at the rear of the motor 23, which particularly allows for optimization of airflow in the cooling circuit. In particular, positioning the propeller at the rear of the motor 23 allows for limiting pressure drop.

[0090] Preferably, the portable housing 10 includes a receiving member 29, which includes an inner wall defining a cavity in which the motor 23 is disposed. Therefore, the receiving member 29 is preferably included in the ironing head 2. The receiving member is in... Figure 7 As shown in the figure, it represents a portion of the cross-sectional view CC of device 1, the section of which is in Figure 6As shown in the diagram. The receiving component 29 includes blades 204 extending from the inner wall to form at least one suction air flow channel between the air suction port 22 and the suction air outlet port 201 on the one hand, and at least one cooling duct on the other hand to allow cooling air entering through at least one cooling air inlet port 203 to flow into the cavity. Therefore, the receiving component 29 is cleverly designed to allow for separate and distinct cooling circuits and air suction circuits. Furthermore, the receiving component 29 allows cooling air to flow near the motor 23 while preventing the flow of suction air (containing steam) near the motor 23. Advantageously, as... Figure 5 and Figure 7 As shown, the air suction circuit and cooling circuit are designed so that the suction air flows in a direction orthogonal to the cooling air flow direction at the fabric sheet.

[0091] Preferably, each blade 204 is hollow in order to define at least one cooling duct. Also preferably, the suction airflow channel is defined between two blades 204.

[0092] Preferably, the receiving component 29 has an air-rectifying function. More precisely, each blade 204 preferably has a curved shape to rectify the suction air flowing between at least one air suction port 22 and the suction air outlet 201. Thus, the suction air is guided and flows more rapidly.

[0093] The operation of the device will now be described.

[0094] When the user wishes to use the device, he fills the reservoir 62 with liquid (preferably water) and then starts the device 1 by pressing a button to power it on. It is assumed that the device has previously been connected to the household power grid via electrical wires. Power is then supplied to the heating elements of the primary steam generator 61 and, if necessary, the secondary steam generator 25 to reach their operating temperatures, advantageously regulated by a thermostat.

[0095] When the user wishes to use the device in the vertical ironing position, he makes the processing surface 20 face vertically toward the fabric to be ironed, and then presses the control device 8 (preferably a button), which has the function of running the pump 63 and allowing liquid to flow from the reservoir 62 to the primary steam generator 61.

[0096] The steam generated in the primary steam generator 61 then escapes through the conduit 4 toward a possible secondary steam generator 25, and then through the steam outlet hole 24. The steam then diffuses onto the fabric sheet, which, combined with the heating and drying effect of the treatment plate 200, allows it to be ironed.

[0097] Simultaneously, a control device 8 can be provided to activate air suction in conjunction with steam emission. For example, a press control device 8 can allow power to be supplied to the motor 23, thereby starting the motor. The fan 21 is then driven to rotate, and air is drawn in through the suction port 22. Suction specifically allows the fabric sheet to be pressed against the processing surface 20. Therefore, the combination of steam emission and suction allows for optimized ironing. Furthermore, air suction also allows for faster drying of the portion of the fabric sheet that has just been steamed. It has been found that this specific method allows for a longer period of ironing effect to be maintained over time after processing the fabric sheet.

[0098] According to another embodiment, the control device 8 allows the user to control the suction in a manner independent of the control of steam discharge. Therefore, the user can control steam discharge alone or in combination with suction control.

[0099] During processing, the user can move the device 1 vertically, for example from top to bottom, to process all or part of the fabric sheet.

[0100] The device 1 can also be used occasionally in a horizontal ironing position, for example, by placing the processing surface 20 horizontally above the fabric sheet to iron a fabric sheet placed horizontally on a table.

[0101] This invention is not limited to the embodiments described and shown in the accompanying drawings. Modifications are still possible without departing from the general teachings, particularly in terms of the configuration of various technical features, or by substitution with technical equivalents.
