Temperature control method of water heating electric appliance

Abstract

The invention relates to a temperature control method of a water heating electric appliance. The control method comprises the steps that water is controlled to flow into a waterway in the water heating electric appliance, and a heater in the water heating electric appliance is controlled to work so as to stabilize the water outlet temperature at a set preset temperature T0; then the heating poweris improved, the outlet water temperature is controlled to stably rise, the outlet water temperature T is detected in real time, when the temperature rising speed of the outlet water temperature T suddenly changes, it is judged that water in the heating electric appliance is boiled, and then the temperature before the temperature rising speed suddenly changes is determined as the boiling temperature W. According to the temperature control method of the water heating electric appliance, the actual boiling point of the water heating electric appliance can be accurately determined, that is, the water heating electric appliances installed in different areas can obtain more accurate actual boiling point temperature values, and compared with a boiling point temperature value simply calculated according to altitude information of the place where the water heating electric appliance is located, the method has the advantages that the influence of other factors on the boiling point temperature can be avoided, and the accuracy is higher.

Description

technical field [0001] The invention relates to a temperature control method of a water heating appliance. Background technique [0002] Under the influence of air pressure in different regions, water will have different boiling points. This is relatively difficult for various electrical appliances with water heating functions. Different boiling points in different regions will cause boiling water vapor to appear at different temperature points when water is heated. For example, in high-altitude areas, the boiling point of water is relatively low. When the water is heated, it is easy to exceed the boiling point and generate steam. Especially for countertop instant water purifiers, steam will appear once the user receives the water. , can easily cause burns to the user. In addition, steam occurs when the user receives water, which also affects the user experience. It is also for this reason that the sales of water heating appliances in the high sea wave area are restricted...

Problems solved by technology

For example, in high-altitude areas, the boiling point of water is relatively low. When the water is heated, it is easy to exceed the boiling point and generate steam. Especially for countertop instant water purifiers, steam will appear once the user receives the water. , can easily cause users to burn

In addition, steam appears when the user receives water, which also affects the user experience

It is also for this reason that the sales of water heating appliances in the high sea wave area are restricted

However, if a condensing structure is used to condense the water outlet to eliminate steam, it will cause waste of energy, increase product volume and increase product cost
