Intelligent time-sharing control method of hot water circulation and gas water heater

Abstract

The invention relates to the technical field of household appliances, in particular to an intelligent time-sharing control method of hot water circulation and a gas water heater. The intelligent time-sharing control method of hot water circulation comprises the steps that through an intelligent circulation mode, the heating time and preheating temperature of water are recorded and updated at different times in a preheating procedure so as to optimize the preheating procedure, the optimized preheating procedure is started during re-preheating at the same time period, and preheating at different times during many times of water utilization and preheating suspension carried out when no water is utilized are achieved. The gas water heater is further provided. The intelligent time-sharing control method of hot water circulation is adopted for preheating. The gas water heater comprises a shell. A heat exchange device, a circulation device, a water flow regulation device, a control device and a temperature induction device are mounted in the shell. The control device is connected with the heat exchange device, the circulation device, the water flow regulation device and the temperature induction device. Time-sharing control can be intelligently achieved according to the living habits of users when a hot water system operates, and energy and water are saved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an intelligent time-sharing control method for hot water circulation and a gas water heater. Background technique [0002] A water heater refers to a device that raises the temperature of cold water into hot water within a certain period of time through various energy exchanges. According to different principles, it can be divided into electric water heaters, gas water heaters, solar water heaters, magnetic energy water heaters, and air energy water heaters. [0003] Most of the existing domestic hot water is supplied by water heaters. Among them, in the domestic hot water supply system, in order to prevent the inconvenience caused by the cold water in the pipeline caused by the excessive length of the water supply pipeline and the natural heat dissipation of the pipe wall, etc., heat source heat is usually used. The method of continuously circulating water in the p...

AI Technical Summary

Problems solved by technology

[0005] The disadvantage of manual control is that it needs to be operated every time water is used, and it needs to wait for a period of time, which is inconvenient

The disadvantage of timing control is that it needs to adjust the time interval according to the user's water habits and ambient temperature, which does not solve the problem of cold water when a small amount of water is used irregularly

[0006] The disadvantage of temperature control is that the water point (or on the circulation pipeline) is affected by the accuracy of the sensor, the installation location, the living environment and the installation method, and it is inconvenient to install; in addition, due to the difference in temperature drop between day and night, when the machine is not used at night, the machine frequently starts to pre-set heat, causing thermal energy loss and noise at night
