DETAILED DESCRIPTION

(21) Referring to the drawings and in particular to FIG. 1, an exemplary embodiment of a clothing iron according to the present disclosure is shown and is generally referred to by reference numeral 10. Advantageously, clothing iron 10 has a soleplate 12 with a curved edge so that a user can freely iron in any direction without being trapped by collar, buttons or pockets. This curved edge design of soleplate 12 allows for smooth gliding on any area of a garment. Another advantage of clothing iron 10 is that soleplate 12 has a construction that applies sheet metal to form soleplate 12 and a steam boiler assembly 1200 (FIG. 12) that can be mounted on soleplate 12.

(22) Referring to FIGS. 1-11, clothing iron 10 heats soleplate 12 for ironing a garment. Referring to FIGS. 1 and 2, soleplate 12 has an edge wall 15 that extends from a horizontal plate 17. Edge wall 15 extends around the entire perimeter of horizontal plate 17. Edge wall 15 forms a left edge 14, a right edge 16 and a back edge 18. Left edge 14, right edge 16 and back edge 18 are rounded. Left edge 14 has a first fillet radius R1, right edge 16 has a second fillet radius R2 and back edge 18 has a third fillet radius R3. First fillet radius R1, second fillet radius R2 and third fillet radius R3 are each more than 3 millimeters (mm), preferably between 3 mm to 10 mm. The first fillet radius R1 of left edge 14, second fillet radius R2 of right edge 16 and third fillet radius R3 of back edge 18 can have varying radii edges so that first fillet radius R1, second fillet radius R2 and third fillet radius R3 are different. First fillet radius R1 can vary along left edge 14. Second fillet radius R2 can vary along right edge 16. Third fillet radius R3 can vary along back edge 18. First fillet radius R1 and second fillet radius R2 can form a radii edge of greater radius ranges toward a front section 19 of soleplate 12 relative to a rear section 21 of soleplate 12.

(23) Referring to FIG. 3, edge wall 15 has an edge height H1 of at least 6 mm, preferably, 6 mm to 100 mm, along left edge 14, right edge 16 and back edge 18. Edge height H1 can vary along each of left edge 14, right edge 16 and back edge 18. This edge height H1 of left edge 14, right edge 16 and back edge 18 is significantly different from traditional one piece die-cast soleplate irons. Accordingly, soleplate 12 has a sharp corner at a corner 13 with high walls and negative vertical angle (e.g. the angle of edge wall 15 to horizontal plate 17 is greater than 90 degrees if an inside angle is measured). As shown in FIG. 4, edge wall 15 forms a left seam 113a where corner 13 intersects with left edge 14 and a right seam 113b where right edge 16 intersects with corner 13. Edge wall 15 comprises an apex 115 at front section 19. Left edge 14 is adjacent to apex 115 and extends to back section 21. Right edge 16 is adjacent to apex 115 and extends to back section 21. Back edge 18 is located at back section 21 adjacent to and located between left edge 14 and right edge 16. Apex 115 forms a tip edge that is angularly offset from each of left edge 14 and right edge 16 so that left seam 113a separates the tip edge from left edge 14 that extends from soleplate 12 toward the top 117 of edge wall 15, and right seam 113b separates the tip edge from right edge 16 that extends from soleplate 12 toward the top 117 of edge wall 15. Corner 13 can push wrinkles away. Advantageously, soleplate 12 having left edge 14, right edge 16 and back edge 18 forms a front end geometry including corner 13, which is more like the bow of a ship cutting thought water, in contrast to a flat edge that can snag a button.

(24) Referring to FIG. 11, soleplate 12 can be modified to soleplate 12a that is the same as soleplate 12 except soleplate 12a has a corner 13a that is modified from corner 13 so that corner 13a is curved to be wider and more rounded than corner 13. Soleplate 12a has the same advantages as soleplate 12, and, in particular, neither soleplate 12 nor soleplate 12a is a flat edge that snags a button. Corner 13a allows for smooth gliding of clothing iron 10 on any area of the garment being ironed.

(25) Advantageously, left edge 14, right edge 16 and back edge 18 of the soleplate are of a more rounded radius than typical clothing irons, and that they have a taller vertical height than the typical clothing irons. The radii profile of soleplates 12, 12a and the radii/corner curves of first fillet radius R1, second fillet radius R2 and third fillet radius R3 are much more gradual. These rounded radii of first fillet radius R1, second fillet radius R2 and third fillet radius R3 permit smooth passing over seams and no snagging on buttons.

(26) Referring to FIG. 1, clothing iron 10 has soleplate 12, a temperature indicator 20, a water spray button 22, a steam dial 24, a steam burst button 26, a water tank 28, a nozzle spray 30 and a power cord 31 that is partially shown.

(28) Referring to FIG. 12, clothing iron 10 has soleplate 12, a hand cover assembly 1202, a printed circuit board (PCB) 1204, a handle base 1206, an upper housing 1208, water tank 28, a fluid pump 1212, and steam boiler assembly 1200 that are connected when assembled. PCB 1204 can have a controller, for example, a microcontroller unit that controls operation of clothing iron 10. Water tank 28 receives water through a water inlet 1217.

(29) Still referring to FIG. 12, water tank 28 has a first water tank outlet 1211, a second water outlet 1213 and a third water outlet 1215. Steam burst button 26 can open and close first water tank outlet 1211 either mechanically, for example, by a valve, or steam burst button 26 can provide input to the controller of PCB 1204 to activate and deactivate a structure to open and close first water tank outlet 1211. First water tank outlet 1211 is connected to a burst steam water inlet 1218 by tubing 1233. Water spray button 22 can open and close second water outlet 1213 either mechanically, for example, by a valve, or water spray button 22 can provide input to the controller of PCB 1204 to activate and deactivate a structure to open and close second water outlet 1213. Second water outlet 1213 is connected to nozzle spray 30 by tubing 1235. Third water outlet 1215 of water tank 28 is connected to fluid pump 1212 through by tubing 1237.

(30) Referring to FIGS. 13 and 14, steam boiler assembly 1200 can be connected to soleplate 12 by brackets 1214. Brackets 1214 are connected to both steam boiler assembly 1200 and soleplate 12 by fasteners, for example, screws, or welding, adhesive or other connector.

(31) Referring to FIG. 15, steam boiler assembly 1200 has a boiler 1201 and a cover 1203. Steam boiler assembly 1200 has a continuous steam water inlet 1216 and burst steam water inlet 1218 through cover 1203. Steam boiler assembly 1200 receives water through continuous steam water inlet 1216 and burst steam water inlet 1218. Steam boiler assembly 1200 further has a heater 1220 and thermostat 1222 through cover 1203. Referring to FIG. 16, steam boiler assembly 1200 has continuous steam outlets 1224, 1226 and a boiler burst steam outlet 1228 through boiler 1201.

(32) Referring to FIGS. 17 and 18, boiler assembly 1200 has cover 1203, a boiler side wall 1230, a boiler lower wall 1231 (FIG. 16) and interior walls 1232 that form a continuous steam path 1234 and a burst steam path 1236 so that boiler assembly 1200 has two steam chambers, one for continuous steam and the other for burst steam. Continuous steam path 1234 is shown by solid arrows 1239 and burst steam path 1236 is shown by arrows 1241 having broken lines. Continuous steam path 1234 is separated from burst steam path 1236.

(33) During operation of clothing iron 10, a user connects power cord 31 to a power source to provide power to PCB 1204, fluid pump 1212 and/or heater 1220 during operation. Heater 1220 increases in temperature during operation. The temperature of heater 1220 is controlled by thermostat 1222 and/or the controller of PCB 1204. Fluid pump 1212 can operate to generate a flow of water from water tank 28 through third water outlet 1215, through tubing 1237, through fluid pump 1212, through tubing 1243, through continuous steam water inlet 1216 into continuous steam path 1234 of boiler assembly 1200. As shown by solid arrows 1239, water in continuous steam path 1234 that is heated by heater 1220 to form steam flows from continuous steam water inlet 1216 to continuous steam outlets 1224, 1226 and through continuous steam outlets 34 to contact fabric that is being ironed by the user. PCB 1204 can control fluid pump 1212 to provide water to continuous steam water inlet 1216 to continuously provide steam through continuous steam outlets 1224, 1226 during operation of clothing iron 10. Thus, fluid pump 1212 can draw water or fluid from water tank 28 to continuous steam path 1234 to generate continuous steam. Steam dial 24 can adjust an amount of steam through continuous steam outlets 1224, 1226, for example, by adjusting the speed of fluid pump 1212.

(34) As shown by arrows with broken lines 1241, water in burst steam path 1236 that is heated by heater 1220 to form steam flows from burst steam water inlet 1218 to boiler burst steam outlet 1228. The user can selectively depress steam burst button 26 to open the valve allowing water to flow from water tank 28 through first water outlet 1211, through tubing 1233, through burst steam water inlet 1218 into burst steam path 1236 of boiler assembly 1200. As shown by arrows 1241 having broken lines, water in burst steam path 1236 that is heated by heater 1220 to form steam flows from burst steam water inlet 1218 to boiler burst steam outlet 1228 and through burst steam outlet 32 to contact fabric that is being ironed by the user to provide steam on demand during operation of clothing iron 10, for example, water and/or steam flows from water tank 28 to boiler burst steam outlet 1228 by gravity. When the user releases steam burst button 26, then the valve closes blocking water from flowing out of first water outlet 1211.

(35) The user can selectively depress water spray button 22 to open the valve allowing water to flow from water tank 28 through second water outlet 1213, through tubing 1235, through nozzle spray 30 to provide a water spray on demand during operation of clothing iron 10. For example, water flows from water tank 28 to nozzle spray 30 by gravity. When the user releases water spray button 22, then the valve closes blocking water from flowing out of second water outlet 1213.

(36) Alternatively, boiler assembly 1200 can be modified to have only one steam chamber without burst steam function. Another alternative is clothing iron 10 can omit fluid pump 1212 and the water can drip into continuous steam path 1234 by gravity.

(37) Advantageously, boiler assembly 1200 is a small sized die-cast boiler that is light weight and with a high steam rate. Boiler assembly 1200 can be a small size die-cast boiler that is the same as a garment steamer that is light weight and with a high steam rate.

(38) Referring to FIGS. 19 and 20, another embodiment of the present disclosure is directed to a clothing iron 10b. Clothing iron 10b is similar to clothing iron 10 of the first embodiment except the soleplate 12b has a different geometry in certain components. Also, clothing iron 10b has an elongated nozzle spray 30b of a different shape than nozzle spray 30 of the first embodiment. The corner 13b of soleplate 12b defines a sharp center ridge as compared to a flattened bevel defined by corner 13 in the first embodiment of soleplate 12. Corner 13b forms a single seam 1113 at the tip/point at the front of corner 13b.

(39) While the present disclosure has been described with reference to one or more exemplary embodiments, it will be understood by those skilled in the art that various changes can be made and equivalents may be substituted for elements thereof without departing from the scope of the present disclosure.
