AI Technical Summary

Technical Problem

After the existing water heater stops use of water, the water continues to heat up due to the residual heating effect of the heating parts, resulting in the problem of high water temperature at the moment of starting up, which reduces the safety of use.

Method used

A water heater is designed, including a heating chamber, a buffer water tank and a connecting water pipe. The hot water discharged from the heating chamber is initially cooled by the buffered cooling water in the buffer water tank, and then mixed with the cold water in the connecting water pipe for secondary cooling to ensure that the hot water reaches a safe temperature before exiting the water.

Benefits of technology

Through the two-stage cooling mechanism, the problem of water heater closed water temperature rise is effectively solved, the safety of use is improved, and the constant temperature water outlet effect is ensured.

Abstract

The invention relates to the technical field of hot water equipment, in particular to a water heater and a constant-temperature water outlet method of the water heater. The water heater comprises a water inlet pipe, a heating cavity, a buffering water tank and a communicating water pipe, the heating cavity communicates with the water inlet pipe and is used for storing hot water, buffering cooling water is stored in the buffering water tank, and the water inlet end of the communicating water pipe communicates with the water inlet pipe; hot water discharged from the heating cavity is introduced into the buffer water tank to be mixed with the buffer cooling water, then is mixed with the cold water introduced into the communicating water pipe and then is discharged, or the hot water discharged from the heating cavity is mixed with the cold water introduced into the communicating water pipe, then is introduced into the buffer water tank to be mixed with the buffer cooling water and finally is discharged. According to the water heater provided by the invention, through the combined action of the buffer water tank and the communicating water pipe, the problem that the water temperature rises when the water heater is closed is more timely, continuously and effectively solved. The constant-temperature water outlet method of the water heater is applied to the water heater, and the problem that the water temperature rises when the water heater is closed is solved more timely, continuously and effectively.
