Water heater control method

Abstract

A water heater and a control method thereof are disclosed. A water heater includes a pressure-bearing water tank, a manual operation device and a detection controller. The pressure-bearing water tank includes a shell and temperature sensing elements mounted on the shell. A hot water outlet is mounted on the upper portion of the shell and a supplementary water inlet is mounted on the lower portion of the shell. The number of the temperature sensing elements mounted on the shell is n, wherein n is an integer and n=2. There exists a difference of height between the installation positions of the two adjacent temperature sensing elements. The detection controller has a single chip and includes a control circuit and a display circuit. The control circuit includes a detection module, a judgment module and an on / off control module for the water heating unit.

Description

technical field [0001] The invention belongs to the technical field of water heaters, and in particular relates to a water heater control method. Background technique [0002] The pressurized water tank is a common part of the water heater, which includes a tank body and a temperature sensing element. The existing pressurized water tank generally has only one temperature sensing element. When working, the temperature sensing element outputs the temperature signal it senses to the control The circuit is used to control whether the water heater is heated, and the temperature sensing element also displays and outputs the temperature signal sensed at the same time, so that the user can know the temperature of the hot water in the water heater and the amount of available hot water. [0003] The characteristics of the water tank when under pressure are: the water tank communicates with the water pipe, so the water tank also bears the pressure in the water pipe at the same time, an...

AI Technical Summary

Problems solved by technology

Since the traditional pressurized water tank has only one temperature sensing element, which is located in the middle of the water tank, its sensing accuracy is low, and it cannot accurately sense the water temperature in various places inside the water tank, and at the same time, it cannot accurately sense the remaining available hot water in the water tank For example, there is obviously hot water inside the tank, but the temperature of the displayed hot water is very low, and it is not convenient to control the water heater

Therefore, the temperature displayed by the temperature of the pressure-bearing water tank used in the existing ordinary water heaters sometimes cannot be consistent with the temperature display of the hot water outlet of the pressure-bearing water tank. The display is low, but at this time, there is still hot water in the upper part of the water tank, resulting in the presence of hot water in the water tank, but the user-side wire controller shows that the water temperature of the water tank is very low, which causes the user to misunderstand the hot water output of the unit and the water temperature of the water tank. misunderstandings and complaints
