Water dispenser airtight heating device and method

Abstract

The invention relates to a device and a method for an airtight heating device of a water dispenser. The device comprises an inner container, a heating plate, a water inlet pipe, and a water outlet pipe. The heating plate is used to heat the inner container. The inner container is provided with a water inlet and a water outlet. The water inlet is connected with the water inlet pipe. The water outlet is connected with the water outlet pipe. The device is characterized in that the inner container is airtight, and the device for an airtight heating device of a water dispenser also comprises a water inlet switch, a water outlet switch, and a controller. The water inlet switch is connected with the water inlet pipe, and the water outlet switch is connected with the water outlet pipe. The controller controls on-off of the water inlet switch and the water outlet switch. The inner container of the airtight heating device of a water dispenser can prevent external air from entering, and back surge phenomenon would not occur when liquid is heated to temperature above boiling.

Description

technical field [0001] The invention relates to a heating technology, in particular to a water dispenser airtight heating device and method. Background technique [0002] One end of the heating liner of the existing water dispenser is directly connected to the bucket, and the other end is connected to the ventilation pipe, and the ventilation pipe is connected to the atmosphere. When the heating liner is working, as long as the liner is not full, the water in the water bucket will continue to enter the liner , The heating plate of the liner heats the inner plate according to the temperature control, and the gas or expansion generated by heating is discharged from the ventilation pipe, so that the pressure in the liner will not be too high and the water will flow back to the bucket. But this kind of water dispenser has the following problems: 1. Because the inner tank is not sealed, harmful substances in the air can enter the inner tank through the ventilator to pollute the w...

AI Technical Summary

Problems solved by technology

But this kind of water dispenser has the following problems: 1. Because the inner tank is not sealed, harmful substances in the air can enter the inner tank through the ventilator to pollute the water source, and the ventilator is exposed to the air for a long time, and if it is not cleaned regularly, dust will accumulate Blockage affects ventilation; 2. The inner tank is directly connected to the water tray and the air, so that the inner tank cannot heat the water to boiling. Once boiling, the water will flow back from the water receiving bucket and the ventilation pipe; 3. The heating plate only depends on the temperature Controlling the heating of the inner tank will cause repeated heating of the same water source. If the heating power is not turned off, the water in the inner tank will be continuously heated repeatedly. Frequent changes in water temperature will cause the water quality to fail to meet drinking health requirements, and when the inner tank is dry The heating plate will still work when the heating plate is used, and there is a potential safety hazard
