Description

Technical Field

[0001] This utility model relates to a device for an electric water heater, and more particularly to an electrical isolation wall that also serves as a water outlet. Background Technology

[0002] The existing technology, Chinese patent 202321081623.7, describes a water outlet with an electric insulator, a heating element, and a water heater. The water heater includes a heating element, which includes a water outlet with an electric insulator. The water outlet with the electric insulator includes a water outlet pipe and an inner core. The upper end of the water outlet pipe is a water inlet, and the lower end is a water outlet. The inner core includes an upper end plate, a lower end plate, and N partitions, where N is an odd number greater than or equal to 3. Each partition is disposed between the upper end plate and the lower end plate, and one side of each partition is connected to the others. The upper end plate, the lower end plate, the inner wall of the water outlet pipe, and the partitions of two adjacent partitions form a water flow channel. The upper and lower ends of two adjacent water flow channels are connected sequentially. The upper end plate has an upper notch for connecting the water inlet to the upper end of the first water flow channel, and the lower end plate has a lower notch for connecting the water outlet to the lower end of the last water flow channel. Each partition 23 on the inner wall of the water outlet pipe 1 is provided with a limiting groove 13, and each partition 23 is slidably connected to the limiting groove 13. The limiting sliding cooperation between the limiting groove 13 and the partition 23 facilitates the assembly and positioning of the inner core 2 and the water outlet pipe 1, preventing relative rotation of the inner core 2 inside the water outlet pipe 1. The problem is that the structure is complex, and there is a risk of interconnected water channels leading to a shortened water path. Utility Model Content
