Instant heat adjustable water dispenser and its control method

Abstract

The invention provides an instantaneous temperature-adjustable drinking water dispenser and a control method thereof. The drinking water dispenser comprises a machine body (1), a heating device (2), a water outlet valve (4), a water storage tank (7) and a control system, wherein the water storage tank (7) is arranged on the upper part of the machine body (1), the water storage tank (7) is communicated with the water inlet of the heating device (2) through a water tank water outlet (8) arranged at the bottom of the water storage tank, a water inlet valve (10) is arranged on a pipeline connecting the water tank water outlet (8) and the heating device (2), the water outlet of the heating device (2) is connected with the water outlet valve (4), a water pump (11) is also arranged between the water tank water outlet (8) and the heating device (2). As the mode of using the water pump to feed water is adopted for the drinking water dispenser, the discharged water is more stable, the water temperature can be adjusted freely and the different demands of consumers on the water temperature can be met; and the water-discharging time is shortened to 2-5 seconds and the defects of the instantaneous drinking water dispenser such as long water-discharging time and low dosage of the discharged water can be overcome. The control method of the instantaneous temperature-adjustable drinking water dispenser is simple in operation and convenient in control.

Description

technical field [0001] The invention belongs to the technical field of water dispensers, and in particular relates to an instant hot water dispenser capable of adjusting the outlet water temperature and a control method thereof. Background technique [0002] At present, some instant water dispensers use multiple electric heating film heating tubes for heating, such as a kind of instant water dispenser for supplying fresh boiling water disclosed in Chinese Patent Publication No. CN201260606, which includes a body, a bucket, a heater, A water vapor separator, a solenoid valve and a water outlet, the water bucket communicates with the water outlet of the water tank of the heater, the water outlet of the heater is connected with the lower part of the hot water pipe, and the upper part of the hot water pipe is separated from the water vapor The water outlet of the steam separator is connected with the water outlet pipe, and the water outlet pipe is connected with the water outlet...

AI Technical Summary

Problems solved by technology

The beneficial effect of using this quick-heating drinking water heater is that the heating water tank is a flat grid groove with one-way backflow, and the groove and the back of the electric heating film heating plate are sealed and fastened to form a hot water heater with parallel backflow and gradual heating. With a suitable heating controller, the temperature rises quickly, and 150ml of boiling water at 95-99°C can be heated in a short period of 3-5 seconds. However, this heating method is easy to accumulate scale in the pipeline, and the scale cannot be cleaned at the same time.
