Water heating device

Abstract

A water heating device comprises a heating body (1), a water inlet system, a water outlet system and a control system. The water inlet system comprises a water inlet pipeline (2). The water outlet system comprises a water outlet pipeline (3), a water outlet valve (9) and a water use completing button (7). The control system comprises a power switch (6), a power switch timer (8), a temperature sensor (5) and a processor (4). The temperature sensor (5) is arranged outside the heating body (1), is connected with the water outlet pipeline (3), and is used for sensing the temperature of water which is discharged from the water outlet pipeline (3). The processor (4) is connected with the power switch timer (8), the temperature sensor (5) and the water outlet valve sensor (7) respectively. The water heating device has two working states which are the training mode and the automatic mode.

Description

[0001] technical field [0002] The present application relates to a water heating device, in particular to a water heating device capable of automatically controlling heating time. Background technique [0003] Water heating systems can be used in various fields, typically water heaters. Generally, the water temperature during bathing is the human body temperature plus 3 degrees Celsius, which is about 40 degrees Celsius. And the temperature of tap water is generally about 15 degrees Celsius, and it needs to expend a lot of energy to heat tap water from 15 degrees Celsius to 40 degrees Celsius, and the cost is relatively large. In real life, it often happens that the water heater is overheated due to various reasons. For example, the user is worried that there is not enough hot water when taking a bath and would rather prolong the heating time of the water heater, or the user leaves the water heater for some reason after turning on the water heater, causing the water he...

The temperature of tap water is generally about 15 degrees Celsius, and it takes a lot of energy to heat tap water from 15 degrees Celsius to 40 degrees Celsius, and the cost is relatively high.

In real life, it often happens that the water heater is overheated due to various reasons. For example, the user is worried that there is not enough hot water when taking a bath and would rather prolong the heating time of the water heater, or the user leaves the water heater for some reason after turning on the water heater, causing the water heater to run infinitely. Heating until it automatically trips. What is more common is that people usually cannot accurately calculate the heating time required each time. Often, the temperature of the water is still relatively high after use. If things go on like this, it will inevitably lead to huge waste of electricity.

The existing water heating system does not measure the water temperature accurately enough through the temperature sensor
