<p>A primary object of the present invention is to prevent danger, such as an abnormal rise in temperature due to the deterioration of elements of a warmer, such as an electric blanket, when it is erroneously dry-cleaned. To this end, the warmer is provided with a safety device which prevents the supply of electric power to a heater (6) when melted by a dry-cleaning solvent. The safety device is arranged so that a cord end casing (2) is formed from, for example, a resin which is melted by a dry-cleaning solvent when dry cleaning is carried out, so that when it is dry-cleaned, a thin-walled portion (10a) of the cord end casing (2) dissolves so that a leaf spring (3) can project and prevent the insertion of a plug (9) of a controller (11) into the cord end casing (1), (2), thereby preventing the supply of electric power to the heater (6). </p> |
