PROBLEM TO BE SOLVED: To solve problems that a conventional foot warmer is used around feet in a bed and can warm up a lower half body but can not warm up an upper half body, shoulders are cooled down to cause to catch cold especially when it gets cold or a cold wave comes, and a conventional electric blanket warms up a whole body with an exothermic body to bring a sense of incompatibility against natural sleeping causing to be unsatisfiable. SOLUTION: A low temperature upper half body electric warmer under temperature much lower than a conventional foot warmer is used. Air warmed with the low temperature upper half body electric warmer performs a role of air curtain function and can warm up hot the shoulder, the neck, the back, the chest, or the like through a night. Because the electric blanket applies the warmer theory like the low temperature upper half body electric warmer, the blanket can solve conventional defects. COPYRIGHT: (C)2011,JPO&INPIT |
