Detailed Description

As shown in fig. 2, the color-changing display screen electric water heater capable of sensing temperature comprises a shell 1, an inner container 2, a control chip 11, a temperature sensor 12, an LED lamp set and a display screen 3. The inner container 2 is of an upper and lower double-layer structure which are mutually communicated, and a sewage outlet 8, a water inlet 9 and a water outlet 10 are sequentially arranged at the joint of the lower part and the shell 1 from left to right. Cold water enters from a water inlet 9 of the water heater, the water inlet 9 is connected with the lower-layer liner 2, hot water flows out from a water outlet 10, the top end of the water outlet 10 is positioned in the upper-layer liner 2, two through holes are formed between the double-layer liners 2, and exchange between the hot water and the cold water can be carried out. And a heat preservation layer is arranged between the inner container 2 and the shell 1, so that the inner container 2 can be preserved when the heating rod stops heating. The display 3 and the mechanical knob 7 are both positioned at the lower left of the front of the housing 1. As shown in fig. 1, the three LED lamp sets are a green LED lamp set 4, a blue LED lamp set 5 and a red LED lamp set 6, which are all circumferentially surrounding the display screen 3.
