Title:
ELECTRIC HOT-WATER BAG HAVING PTC HEATING PAD
Document Type and Number:
Japanese Patent JP2021041028
Kind Code:
A
Abstract:
To provide an electric hot-water bag having an improved PTC heating pad.SOLUTION: An electric hot-water bag includes a main body and an attachment base 2. A PTC heating pad 1 is fixed to the attachment base 2, the attachment base 2 and the main body are joined to each other in a sealing manner, the PTC heating pad 1 is connected to the attachment base 2, and the PTC heating pad 1 is located in the main body. The main body has further higher sealing performance, and hardly causes leakage. When heating, further equal heat generation becomes possible by the PTC heating pad 1, and occurrence of malfunctions such as water leakage and breakage of the electric hot-water bag caused by a pressure rise in the main body resulting from the unequal heating of the electric hot-water bag due to generation of minute air bubbles can be remarkably avoided, thus achieving further higher safety.SELECTED DRAWING: Figure 1
