1. In addition to heating performance, the electric heating tube has over-temperature abandonment performance: (1) Under normal conditions, the electric heating tube is energized to generate heat and the heating should heat the task medium; (2) When the electric heating tube is dehydrated, and other protective devices ( Temperature control. When the installation of liquid level control fails, the electric heating tube will automatically cut off in about 3 minutes after the power is turned on, thereby eliminating the occurrence of low-temperature burnout of other parts outside the washing machine and ensuring safety.
The geometric shape of the electric heating tube is not only suitable for the liquid heating requirements of the inner tub of the washing machine, but also an installation sleeve. Specifically, the bending and forming of ordinary electric heating tubes are all around the length of the heating zone and the shape of the barrel. The heating tube is determined by the depth of the heated liquid and other conditions. In addition to referring to the above conditions, the middle of the tube body has been designed as a fixed ferrule. During installation, the middle of the heating tube will be matched with the inside of the barrel. The core is fixed. This structure can ensure that the electric heating tube is fixed and fixed (because the washing machine will constantly vibrate when it is running). At the same time, a fixed frame (clamp) is omitted from the design, and the connection is simple and the action is quick.
