Title:
MULTIPURPOSE HEATING PAD
Document Type and Number:
WIPO Patent Application WO/2011/068304
Kind Code:
A3
Abstract:
The present invention relates to a multipurpose heating pad that can be placed atop a chair, mat, or other surface and used or placed below same and used, and more particularly, to a multipurpose heating pad formed as a standalone heating pad including a heating element controlled and operated by a controller that is selectively connectable to an AC power supply or a DC power supply, and one of various types of cover materials in which the heating element is entirely enclosed, wherein the heating pad can be used while placed atop or under any one of various objects that require heating, or can be directly attached to an object and used, such that through a simple adjustment of the size thereof, there are no restrictions with regard to the type of object with which the pad can be used, thus making the pad highly useful. Also, as the pad can be selectively used with an AC power supply, DC power supply, or a rechargeable power supply as required, it can be effectively used indoors, outdoors, and in moving vehicles. Further, when the inner heating element is formed in sections and the sections are sequentially operated, a significant amount of power is saved due to the heating effects of latent heat, thereby enabling a reduction in the power consumed, so as to provide a highly economical heating pad with low power consumption and a greatly extended operating time in the case of a rechargeable power supply.
