Constant temperature instant hot water dispenser

Abstract

The invention discloses a constant-temperature instant water drinking machine, which comprises a water pump, a water tank, a shell, an electric heater and a main control circuit board, wherein the interior of the water tank, by virtue of a partition board A, a partition board B and a partition board C, is divided into a water storage cavity, a balancing cavity, a heating cavity and a water outlet cavity; the heating cavity and the balancing cavity, at the lower ends, are communicated by virtue of a water inlet hole on the partition board B; the heating cavity and the balancing cavity, at the upper ends, communicate with a gap in the top wall of the water tank by virtue of the partition board B; the heating cavity and the water outlet cavity, at the upper ends, communicate with the gap in the top wall of the water tank by virtue of the partition board A; and the water storage cavity and the balancing cavity, at the upper ends, communicate with the gap in the top wall of the water tank by virtue of the partition board C; when water inside the balancing cavity overflows the maximum water level of the balancing cavity, the overflowing water completely flows into the water storage cavity, and the water in the heating cavity, when reaching the maximum water level of the heating cavity and becoming boiling, turns over the partition board A and enters the water outlet cavity. The water drinking machine disclosed by the invention has the advantages that water-outlet temperature is constantly kept at the boiling point of the water and is free from the interference of environment and water source temperature; the entire water drinking machine adopts integrated design, so that the external connection of a water barrel is avoided; and the water drinking machine is convenient for carrying and beautiful in appearance.

Description

technical field [0001] The invention relates to an electric heating water dispenser, in particular to a constant temperature instant hot water dispenser. Background technique [0002] The instant hot water dispenser is a water dispenser in which hot water can be dispensed immediately without waiting. At present, the common instant hot water dispenser includes a control circuit board, a water pump, a temperature sensor, a water level sensor, a heater and a water tank. The water level in the water tank is used to start heating. The heater heats the water in the water tank instantaneously and then flows out from the water outlet. The parameters obtained by the water inlet temperature sensor and the water outlet temperature sensor are comprehensively calculated by the control circuit board, and then the control circuit board adjusts the water pump and Heating body power, to achieve the set water temperature value. [0003] The disadvantage of the existing instant hot water dis...
