Constant-temperature quantitative instant heating type water dispenser

Abstract

The invention provides a constant-temperature quantitative instant heating type water dispenser. The constant-temperature quantitative instant heating type water dispenser comprises a shell body, a water tank, a water pump, a touch panel, a PLC, a heater set, a hot water pipe, a water outlet pipe, a circulating water pipe, a cold water pipe, a flow detector and a temperature sensor, wherein the heater set comprises a first-stage heater, a second-stage heater, a third-stage heater, a fourth-stage heater, a fifth-stage heater, a sixth-stage heater and a seventh-stage heater; and water heating temperature ranges of the seven heaters are respectively 30-40 DEG C, 40-50 DEG C, 50-60 DEG C, 60-70 DEG C, 70-80 DEG C, 80-90 DEG C and 90-100 DEG C. According to the water dispenser, the water outlettemperature and the water outlet amount can be intelligently set, water can be heated in a graded and layered mode, the heating speed can be increased, the accuracy of the water outlet temperature can be improved, and accurate temperature control can be achieved; and the circulating water pipe can circularly heat the retained cold water in the pipeline, so that the retained cold water in the pipeline can be prevented from directly entering the water receiving container through the water outlet pipe to influence the water receiving temperature.

Description

technical field [0001] The invention belongs to the technical field of water dispensers, and in particular relates to a fixed-temperature and quantitative instant-heat water dispenser. Background technique [0002] The instant hot water dispenser can use a heating body with strong thermal conductivity under high power state to convert electric energy into heat energy, and then transfer the heat to the water, so that the water can be heated rapidly by using powerful heat. The working principle of the instant water dispenser is to use the control module to control the water pump to continuously inject cold water into the heater. At the same time, the control module is connected to the heating power of the heater. When the cold water flows through the heater, it is heated and flows out through the pipe. All that is hot is hot water. [0003] However, when the existing instant water dispenser heats cold water, the cold water flows through the heater and there are problems that ...
