System for precisely controlling water outlet temperature of quick-heating module and construction method of system

Abstract

The invention relates to a system for precisely controlling the water outlet temperature of a quick-heating module. A preheating water circulation device comprises a preheating water tank, and a wateroutlet end of the preheating water tank is connected with a water inlet end of the quick-heating module through a water pump; a water outlet end of the quick-heating module is divided into two paths,wherein one path is connected with a water return end of the preheating water tank through a third electromagnetic valve, and the other path is connected with a water outlet through a fourth electromagnetic valve; a first temperature sensor is arranged at the water outlet end of the quick-heating module; a second liquid level switch is arranged in the preheating water tank; a water outlet end ofa water purifying tank is connected with a water inlet end of the preheating water tank through a second electromagnetic valve; a control system controls a third electromagnetic valve and the fourth electromagnetic valve to be switched on and switched off according to feedback signals of the first temperature sensor, and controls the second electromagnetic valve to be switched on and switched offaccording to feedback signals of the second liquid level switch. According to the system, electric power of the quick-heating module is not increased, and electrical safety is guaranteed; the temperature and flow of outlet water of water drinking equipment can be greatly increased; the temperature value of the temperature of the outlet water can be precisely controlled, and the user experience isimproved.

Description

technical field [0001] The invention relates to a system for precisely controlling the outlet water temperature of a fast heating module and a construction method thereof. Background technique [0002] The fast heating module has been widely used in drinking water equipment, and its main advantage is to raise the water temperature to the required temperature in a relatively short period of time. When a higher water temperature is required, the temperature difference is too large, and it is difficult for the fast heating module to rise to the required temperature in a short time. The requirements will be higher, which will increase the potential safety hazard; the existing drinking water equipment generally uses the water pump to control the water flow to ensure the outlet water temperature, the water flow is small, resulting in a small hot water flow, and the user has to wait a long time For a long time, it also affects the user experience.
