Definitions
- the present invention refers to an iron, both for professional use and for domestic use, in particular a steam iron in which steam is generated inside the iron itself.
- Irons provided with a water tank and a boiler, or an evaporation chamber, in which, by means of an electrically heated element, the water coming from the tank is transformed into steam, which is then delivered to the outside through an ironing sole plate provided with holes for the delivery of the steam itself, in order to improve the ironing, are known.
- the tank and the evaporation chamber are fluidically communicating and a selector is normally interposed between them which, if operated by a user, allows the water contained in the tank to pass towards the evaporation chamber.
- the evaporation chamber is in turn communicating with the holes on the ironing sole plate from which the generated water steam can exit, which then spreads onto the garment being treated.
- the aforesaid selector has only two functioning positions, namely a closed position, in which it completely prevents the passage of water from the tank to the evaporation chamber, and an open position, in which it allows it.
- the passage from the closed position to the open position, and vice versa, takes place suddenly and no intermediate positioning is possible.
- steam can only be delivered in fixed and predefined amounts and do not allow a user to modify the amount of steam it is wished to deliver.
- a first drawback of such irons of known type is therefore due to the fact that it is not possible for the user to modulate the steam flow rate generated and delivered on the garment.
- a further drawback of the known solutions is due to the fact that with the passage of water, when the selector is in the open position, water continues to be consumed even when the iron is at rest during ironing and is positioned horizontally.
- a valve operated by a bimetallic sheet that deforms as a function of the temperature inside the evaporation chamber.
- the aforesaid sheet deforms by bending on one side and opening the valve when a certain working temperature sufficient to instantly vaporize the water is reached and exceeded.
- a drawback is due to the fact that the opening for the passage of the water towards the plate is controlled by the bimetallic sheet, whose behaviour depends on the temperature and therefore the user must necessarily adhere to a certain time, which can also be a few minutes, in order to be able to use the steam, effectively increasing the time required to perform the ironing operations.
- valve and the bimetallic sheet need to be calibrated and finely tuned for the desired effect to be obtained. These calibration and tuning operations have a negative impact on the production cost of the iron.
- Document GB2456303A discloses an iron provided with a control device configured to control the energizing current of a solenoid valve to deliver a first steam jet through an ironing plate, followed by a succession of further steam jets having reduced flow rate and/or volume, delivered at certain time intervals when the user presses a steam delivery button.
- the number of jets, the time interval between them and the amount of steam delivered are managed independently by the control device and the user can only change the volume of the second steam jet, or the duration of the energization interval of the solenoid valve, by acting on appropriate knobs.
- Such solution is intended to prevent excessive cooling of the plate due to an excess of water fed to it rather than to allow a quick and intuitive adjustment of the amount of steam by the user during ironing.
- Other irons are described in FR2570098A and FR2766214A.
- An object of the present invention is to realize an iron that allows a user to directly adjust the steam flow rate generated and delivered on the garment to be ironed even during ironing operations.
- Another object of the present invention is to realize an iron that is inexpensive and easy to produce.
- a further object of the present invention is to realize an iron which makes it possible to reduce the time that elapses from switching it on to the moment in which it is possible to generate and deliver steam.
- an iron which overcomes the drawbacks of the prior art and eliminates the defects present therein, comprises: a tank suitable for containing water, steam generating means configured to receive a part of the aforesaid water from the aforesaid tank and to transform it into steam.
- the iron also comprises an adjusting device to allow a user to manually adjust the amount of the aforesaid water transferred from the aforesaid tank to the aforesaid steam generating means from time to time.
- the aforesaid adjusting device comprises a control element configured to generate an electrical signal when it is manually actuated by the user and electrical actuating means controlled by an electronic control unit in response to the aforesaid electrical signal and configured to move a shutter member associated with an outlet opening of the aforesaid tank.
- the electrical signal is variable in a manner proportional to an action exerted by the user on the control element
- electrical actuating means are configured to move the shutter member associated with an outlet opening of the tank in a manner proportional to the electrical signal, to adjust the amount of water fed to the steam generating means and therefore the flow rate of generated steam.
- the adjusting device is configured to allow the user to progressively vary, during ironing, the flow rate of the water transferred to the steam adjusting means.
- control member that generates a variable electrical signal as a function of an action exerted on it, such solution allows an easy and intuitive adjustment of the amount of water.
- “Action” here and below in the description means in general an interaction with the control member such that a force or a contact exerted on it can be varied in order to change the intensity or position thereof, and in which such variation involves a variation in the intensity of the signal.
- the action may be a pressure exerted on a button, or a stroke or a different contact position of a user's finger with respect to touch- sensitive means.
- the iron also comprises a containment structure that defines a handle and in which the aforesaid tank is mounted, and, according to another aspect of the present invention, the aforesaid control element is arranged substantially at the aforesaid handle.
- the aforesaid shutter member is connected to the aforesaid electrical actuating means and is progressively movable with respect to an outlet opening for the water to modify the passage section and adjust the water flow rate.
- the shutter member may assume any intermediate position between a fully closed position, in which it prevents the aforesaid water from exiting the aforesaid tank, and a fully open position, in which the aforesaid water is fed to said steam generating means with the maximum available flow rate.
- said adjusting device further comprises elastic means configured to normally keep the aforesaid shutter member in the aforesaid fully closed position. In this way, when no action is exerted on the electrical actuating means, the shutter member closes the outlet opening and consequently when the iron is not in use it does not deliver steam and no water leakage occurs through the ironing sole plate.
- the aforesaid shutter member has a shuter end, to which there is associated a shuter member cooperating with the aforesaid outlet opening of the aforesaid tank, and an operating end, opposite to aforesaid shuter end, and operable by the aforesaid electrical actuating means to cause a translation of the aforesaid shuter member and consequently move the aforesaid shuter member away from the aforesaid outlet opening and bring it towards at least any desired intermediate position between the aforesaid closed position and the aforesaid fully open position.
- the aforesaid shuter member comprises an oblong stem having, at the aforesaid shuter end, a cavity whose depth is progressively variable along the longitudinal axis of the aforesaid stem.
- the depth of the cavity is increasing in the direction opposite to the direction of the stroke that the stem travels between the fully closed position and the fully open position.
- the aforesaid electrical actuating means comprise a linear actuator having, or consisting of, a solenoid of the type called "push-pull”.
- the aforesaid control element comprises touch-sensitive means suitable for detecting the presence and the position of a user's hand, or a part thereof, and the aforesaid electrical signal is variable as a function of the position of the aforesaid user's hand on the aforesaid touch-sensitive means.
- the aforesaid control element comprises a buton suitable for detecting the pressure exerted by a user who contacts it and the aforesaid electrical signal is variable as a function of the aforesaid pressure exerted by the user on the aforesaid buton.
- the adjusting device is therefore very simple and intuitive to use.
- the aforesaid steam generating means comprise an evaporation chamber having an inlet opening, and a distribution manifold is interposed between the aforesaid outlet opening of the aforesaid tank and the aforesaid inlet opening of the aforesaid evaporation chamber.
- the iron comprises a manually operable selector, arranged upstream of the aforesaid inlet opening of the aforesaid evaporation chamber and configured to selectively obstruct the aforesaid manifold.
- An object of the present invention is also a method of using an iron according to the invention, comprising feeding water from a tank to steam generating means and transforming it into steam.
- the method comprises adjusting the amount of said water transferred from said tank to said steam generating means, wherein to regulate said amount of water it involves regulating an electrical signal proportional to an action exerted by a user on said control element, and controlling by said control unit said electrical actuating means in response to said electrical signal to move said shutter member associated with an outlet opening of said tank in a manner proportional to said electrical signal.
