Abstract
PURPOSE:To prevent freezing by remaining water by forming the holder into the shape which is appropriate to wind around the drain valve of the washer by cutting soft thermoplastic sheet, and by welding the soft tube with the sealed-in heating wire to the holder. CONSTITUTION:The heating pipe 26, which is formed by water-tightly sealing the soft thermoplastic tube 33 in which the freeze preventive heater 23 heating wire 34 is installed, is fitted on the soft thermoplastic holder sheet which is cut into the shape appropriate to be mounted on the drain valve 9. Although the heating wire 34 is connected in series with the heating pipe body 36,36' which is divided into two, if it is connected to each heating pipe 36,36' in parallel, the freeze preventive function can be made the most of when the heating wire 34 on one side is disconnected. Also, for such wide application, dividing the heating pipe 36,36' into two is extremely effective for freeze prevention.
