PURPOSE:To enable a foot warmer to heat effectively one's legs including soles and thighs, by flowing hot air from a hot air generating apparatus, and inflating a hot air bag by the pressure of said warm air. CONSTITUTION:The fresh air taken from an air inlet 4 by a blower 7 is passed via an air channel 8 and is heated by a heater 9. The thus heated air is discharged into a hot air discharging space 6 in a housing 1, and while it heats a foot bearing section 2, it is forced via hot air blowing outlet 3, 3' into the hot air bag 12 to inflate the bag 12. The hot air is discharged through the meshes of the fabric composing the hot air bag 12. The hot air bag 12 can prevent the fresh air from entering the inside of the bag 12, and as the hot air bag 12 is flexible, one's legs can be readily put in the bag 12, and when the foot warmer is not in use, it can be easily stored. |
