Device and method for measuring temperature of water in water heater

Abstract

The invention discloses a device and method for measuring temperature of water in a water heater. The device comprises a semiconductor thermoelectric generator and a single chip microcomputer work device. The semiconductor thermoelectric generator generates electromotive force using temperature difference between water outlet of the water heater and the water inlet of the water heater, so the semiconductor thermoelectric generator is used as a power supply. The single chip microcomputer work device is used for measuring the present temperature of water in the water heater / or residual volume of hot water, and sending measured results to a display device to display. According to the device and method for measuring temperature of water in the water heater, electric power is generated through temperature difference, and low-voltage power is supplied during the whole course, dangers caused by high-voltage power can be prevented, a user can know the present temperature of water and the volume of residual hot water if the water heater is powered down during usage, and the safety can be ensured if the water heater is used when the water heater does not need powering on, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of detection and household appliances, in particular to a detection device and method for water temperature of a water heater. Background technique [0002] At present, when most users use a water heater with a single heating function, they usually cut off the power when using it, so as to avoid safety problems during live use. Among the existing water heaters, some do not have any display function, so the user cannot know the current water temperature and the remaining hot water volume, etc.; there is also a type of water heater with display function, which only has the function of displaying the water temperature. When using a water heater, the corresponding display function cannot be used. [0003] When the user uses the water heater in the above-mentioned prior art, he does not know whether he needs to plug in the power supply to reheat in order to use hot water enough; It is only plugged in and used when the wa...

Problems solved by technology

[0005] The present invention provides a detection device and method for water temperature of a water heater, which is used to solve the problem in the prior art that the current water temperature and the remaining hot water volume cannot be known when the water heater is in use when the power is turned off. Plug-in use increases user safety hazards and lower user experience
