Abstract
An adjustable temperature electric iron (1) comprises a bimetallic strip temperature sensor (3) located at the ironing plate (20) and a temperature display dial (10) for reading the temperature sensed by the temperature sensor (3), this latter being coiled inside a metal tubular housing (4) terminated on the body (24) of the electric iron at the display dial (10). <IMAGE>
Description
SPECIFICATION
Adjustable temperature electric iron
This invention relates to an electric iron including a device for adjusting the ironing temperature, particularly as a household appliance.
Widespread use is made in household electric irons of thermostats to adjust the heat delivered to the ironing hot plate in proportion to the fabric type being ironed. When the ironing temperature must be changed, the iron thermostat is manipulated, and after a while, the hot plate of the iron will assume a different operating temperature; currently, the user has no means to effectively ascertain whether the iron plate has actually achieved the desired temperature.
That situation has obvious disadvantages, especially when shifting from a high temperature to a reduced one to process delicate garments; in such condition, there exists indeed a danger of damaging the garment beyond repair if the time allowed is insufficient.
This invention sets out to provide an electric iron, particularly for household use, including an ironing temperature adjusting device which ensures that the hot plate has reached a desired pre-set operating temperature.
Within that general aim, it is possible to arrange that the electric iron according to the invention has a temperature dial which can be easily read even by an unskilled or absent-minded user, upon inspection.
It is further possible to arrange that the electric iron according to the invention achieves the objects set forth above through a simple construction, relatively easy to manufacture, reliable in operation, as well as effective and of comparatively low cost.
According to one aspect of the present invention, there is provided an electric iron including an ironing temperature adjusting device, particularly for household use, characterized in that it comprises a temperature sensing element located proximate to the ironing plate, and an exposed temperature display dial for reading the temperature sensed by said sensing element.
Further features will be more readily understood from the following description of a preferred, though not limitative, embodiment of this electric iron, with reference to the accompanying exemplary drawing, where:
Figure 1 is a front view, in section, of the electric iron according to this invention; and
Figure 2 is a top plan view of the temperature dial of the temperature adjusting device.
With reference to the figures there is generally indicated at 1 an electric iron according to this invention, and at 2 a device for adjusting the ironing temperature level.
In the particular embodiment shown schematically in Figure 1, said device has been inserted in the area usually occupied by the thermostat in a conventional steam electric iron, the thermostat having been moved to another location.
In Figure 1, the reference numeral 20 designates the ironing plate, the numeral 21 designates the water tank which is penetrated in sealed relationship by a pipe 22 and is supported by a bridge 23 screw fastened to the plate 20, the water tank providing support for the plastics body 24 of the appliance. The device 2 comprises a temperature sensing element consisting of a thermometer 3 of the bimetallic strip type, which is coiled in the configuration of a cylindrical helix inside the metal tubular body or housing 4. To the bottom of the body 4, there is force fitted a metal cap 5, whereto one end of said strip is attached to a stub member 6, whereon a cap 7 is anchored which carries a radially arranged pointer 8.
At the top of the body 4, suitably machined to present a seat 9, there is arranged a dial 10 which is secured to the body 4 by riveting the top of the body 4 onto the dial. Onto the mouth of the body 4, there is force fitted a closing bushing 11 which is centrally penetrated by a bore for the passage of the stub member therethrough.
To protect the pointer 8, there is provided a rounded off corner square dome 12 which is transparent and somewhat flattened, and turned slightly outwards along the edge 1 2a. The dome 12 is attached to the dial 10 as by glueing the cited turned edge 1 2a to the edge of the dial 10.
To anchor the thermometer onto the electric iron, an elastically deformable thin plate 13 is used which is formed with a centrally located opening for the dome 12 to protrude therethrough and snap engages peripherally a frame 14 formed in the plastics portion 24 of the electric iron body.
To the bridge 23, there is attached an aluminum bushing 16, into which bushing the base of the body 4 is inserted to a force fit which effectively delivers heat to the body 4 itself, thereby the thermometer is enabled to accurately read the temperature reached by the plate 20.
The visible side of the dial 10 is advantageously divided into several colored sectors or ranges 1 7a, 1 7b, 1 7c, 1 7d, etc., with colors equal to those on the thermostat, such as to provide intuitive evidence of the ironing temperature; suitably, said dial may be calibrated with graduations for a more accurate reading of the temperature.
The graduated dial 10 may be attached to the top of the bimetallic strip 3, in which case the dome 12 will only include a transparent or clear sector.
The invention achieves its objects, and specifically affords the possibility of ascertaining by a simple inspection when the iron has reached the desired operation temperature.
The invention as described in the foregoing is susceptible to many modifications and variations, all of which are intended to fall within the purview of the instant inventive concept.
Moreover, all of the details can be replaced with other technically equivalent ones.
In practicing the invention, the materials employed, as well as the shapes and dimensions, may be any ones to suit individual applicational requirements, without departing from the scope of the appended claims.
