Drinking machine

Abstract

The invention discloses a water dispenser, which comprises a main body, a hot tank positioned in the main body of the water dispenser, a heating device arranged on the hot tank, and a liquid level control device. The liquid level control device comprises an upper limit trigger device that is not lower than the upper limit water level line of the hot tank and is electrically connected with a startunit of the heating device. When the water in the hot tank is higher than or equal to the upper limit water level line, the upper limit trigger device transmits a trigger signal to the start unit of the heating device to trigger the heating device to heat water. The water dispenser can heat the water in the hot tank only when the water in the hot tank is not lower than the upper limit water levelline, thus obviating frequent heating of water stored in the hot tank. Meanwhile, the water dispenser also includes a water inlet solenoid and a lower limit trigger device of the liquid level controldevice. The upper and the lower limit trigger devices of the liquid level control device can be cooperated with the water inlet solenoid to prevent repeated input of water in the hot tank.

Description

technical field [0001] The invention relates to the technical field of water dispensers, in particular to a water dispenser capable of avoiding repeated heating. Background technique [0002] Common water dispensers currently on the market include: single hot, cold and hot water dispensers. Water dispensers of the type described have a thermal bladder for heating water. A conventional water dispenser includes a hot tank, a heating plate, and a temperature controller. The temperature controller controls the water temperature in the hot tank. When the existing water temperature is lower than a preset value, the temperature controller will trigger the heating The pan heats the water in the bladder. Simultaneously, the water intake of the conventional water dispenser is also usually to supply water successively, as long as the existing water in the described heat bladder is lower than the preset water level, the described water purification bottle will continuously store water...

AI Technical Summary

Problems solved by technology

Even if no one is taking water, it will continue to be heated repeatedly due to natural cooling. In this way, if drinking water is heated repeatedly, harmful substances will be produced, which will affect people's health.
