Intelligent control system of water heater

Abstract

The invention discloses an intelligent control system of a water heater. According to the system, the water temperature value in a water storage tank is obtained in real time through a temperature sensor, and whether water flows at a water inlet pipe or a water outlet pipe of the water heater is detected through a water flow sensor, so that whether the water heater is in a water outflow state or not is judged; a first rated temperature value and a second rated temperature value are preset in a controller; and if the water heater is in the water outflow state, as long as the water temperature value in the water storage tank is not higher than the larger first rated temperature value, a heater is in a starting state all the time. In this way, when the water heater is discharging water, the condition for triggering the heater to stop heating is high, then the heater can be continuously kept in the starting state, and repeated starting and stopping are not likely to occur.

Description

technical field [0001] The invention relates to an intelligent control system for a water heater. Background technique [0002] As a new type of household appliance, water heaters are mostly classified by the energy used to heat water, such as natural gas water heaters, gas water heaters, solar water heaters, and electric water heaters. And the electric water heater wherein is liked by users because of its simple installation and easy to use on the one hand. [0003] In actual use, the water heater will set a temperature value that can be adjusted by the user. When the water temperature in the water storage tank in the water heater is greater than or equal to the temperature value, the water heater will stop heating, thereby avoiding the waste of electric energy caused by the continuous heating of the water heater. , but also to avoid scalding the user due to excessive water temperature. [0004] However, when the water heater is in the water outlet state, since the water ...

AI Technical Summary

Problems solved by technology

[0004] However, when the water heater is in the water outlet state, since the water storage tank will continuously replenish new cold water, the water temperature in the water storage tank will drop rapidly when the heater stops working; therefore, even if the heater makes the water temperature in the water storage tank rise to not less than The preset temperature value, if the user uses water faster, the water temperature in the water storage tank will drop rapidly to less than the preset temperature value, which will cause the heater to start and stop repeatedly, which will shorten the life of the heater
