Problems solved by technology

In this way, the amount of hot water in the inner tank displayed by the temperature change measured by the temperature sensor is also inaccurate.
[0005]The installation position of this kind of temperature sensor makes it very inconvenient to repair or replace once the temperature sensor fails or the connection line has problems

Embodiment approach

[0054] In the second embodiment of the water heater of the present invention, the number of temperature sensors of the water heater of the present invention is four. The four temperature sensors are located in the same cross-section of the outer surface of the inner container 2 near one end of the heating tube 6 .

[0055] The four temperature sensors are specifically the temperature sensor three 12 located at the lowest point on the outer surface of the inner tank of the water heater, the temperature sensor four 10 located in the axial horizontal plane of the inner tank, and symmetrically distributed on the inner tank located at the temperature Temperature sensor one 9 and temperature sensor two 11 on both sides of sensor four 10 .

[0056] The cross section of the inner tank 2 is circular, and the vertical distance between the first temperature sensor 9 and the second temperature sensor 11 and the fourth temperature sensor 10 is preferably 1 / 2 of the radius of the inner tank...

Abstract

The invention discloses a water heater comprising an outer casing and an inner container arranged in the outer casing and a thermal insulation layer positioned between the inner container and the outer casing; the water heater further comprises a controller and a display which is connected with the controller; a temperature sensor which is connected with the controller is arranged on the outer surface of the inner container which is close to one end of a heating pipe, and the temperature sensor transmits real-time measured temperature values to the controller. The invention provides the water heater, thereby facilitating the maintenance and the replacement of the temperature sensor in the water heater and being capable of accurately measuring water temperature of the water heater.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a water heater capable of displaying the amount of hot water. Background technique [0002] In the existing water heater, a temperature sensor is installed at the axial center of the inner tank, and the temperature sensor transmits the measured water temperature to the water heater computer board control system connected with the temperature sensor, and the control system drives the display device to directly display the measured water temperature. [0003] see figure 1 , an existing water heater, five temperature sensors T1, T2, T3, T4, T5 are axially distributed in the central part outside the inner tank. The temperature change measured by the above 5 temperature sensors shows the amount of hot water in the existing inner tank. Since the temperature sensors T1, T2, T3, T4, and T5 of the existing water heater are distributed in the central position of the inner tank, there is a pr...
