DESCRIPTION

Field of the Invention [0001] The present invention relates to irons.

Background to the Invention [0002] For convenience of operation, steam irons include internal reservoirs to hold liquid water for boiling to create steam. A user needs to replace the water in the reservoir as it is used up during ironing. To enable this replacement a filling hole is provided in liquid communication with the reservoir. The filling hole can be located on the handle of the iron so that it is above the reservoir in normal use when the iron is horizontal for ironing and when the iron is generally vertical, stood on its rear when awaiting use. This has the advantage that during normal use, water will not tend to run out of the reservoir and so a valve arrangement is not required.

[0003] In an alternative filling arrangement, more recently a product has been offered with a filling hole mounted in the rear of the iron with a closable door to stop the water coming out of the hole in use. This is intended to make filling the iron from a tap easier. However, in practice, this leaves several problems for the user. First, if the reservoir is overfilled then the excess water quickly runs over the iron. Exacerbating this problem, if the iron is being filled in a sink, then it can sometimes have to be angled to get it under the tap, making visibility of the maximum fill marker difficult. Secondly, although the fill-hole in the rear of the iron is intended to make filling from a tap practicable, it is still difficult to maintain the iron suitably oriented under the flow of water to avoid spillages.

[0006] It is an aim of preferred embodiments of the present invention to obviate or overcome a disadvantage of the prior art, whether such disadvantage or prior art is referred to herein or otherwise.

Summary of the Invention [0007] An iron comprising a filling funnel, characterised in that the funnel is large in that the funnel has an opening and the cross-sectional area of the plane of the opening is at least 50cm^ and wherein the funnel is at the rear of the iron, wherein the exterior of the funnel forms a channel to receive a power cord to enable the exterior of the funnel to function as a cord-wind.

[0008] Further features of the present invention are set out in the appended claims.

Description of the Preferred Embodiments [0010] Referring to figures 1-6 of the accompanying drawings, there is shown an iron 2 comprising a main body 4 and a large funnel 6 at the rear of the iron 2. Externally the main body 4, except for the absence of a filling hole and the presence of a valve trigger 8, is substantially similar to a common steam iron and so will only be described briefly.

[0011] The iron 2 comprises a sole plate 10 on the bottom of the iron 2, a handle 12 at the top of the iron 2, a controller 14, steam buttons 16, 18 and a power chord (only part shown) 20.

[0012] Referring to Figure 7 of the accompanying drawings, internally only those elements of the iron relevant to an explanation of the features of the present invention are shown. Internally, the iron 2 comprises a water reservoir 22 from which extends a tube 24 in liquid communication with the funnel 6. Between the funnel 6 and tube 24 is a valve 26 operable by the valve trigger 8 by a connecting rod 28. The valve 26 is biased to the closed position by a spring 30.

[0013] The funnel 6 shown in Figures 1-7 has an opening 32 into which water can be poured, that is 13cm high and 13cm wide at its widest. The surface area of the opening is approximately 113cm2. The surfaces 34, 36, 38 of the funnel 6 are shaped to provide a generally concave exterior 40 to the funnel 6 providing a suitable chord-wind.

[0014] In use, therefore, a user can fill the water reservoir 22 from a tap, so a jug is not required, and does not need a maximum fill marker because the reservoir 22 can be overfilled, with the excess staying in the funnel 6. The valve trigger 8 is activated by the user to open the valve 26. The reservoir 22 is then filled from a tap. Since the funnel 6 has a large volume, a user has plenty of time to turn off the filling tap before it overflows. The valve trigger 8 is released to allow the valve to close. The excess water is in the funnel 6 and can be discarded at the user's convenience, typically into the sink associated with the tap being used to fill the reservoir 22.

[0015] The opening 32 of the funnel 6 forms a stand for the iron 2 winen it is in a generally vertical position.
