Scale detection method and scale detection device for water boiling utensil

Abstract

The invention provides a scale detection method and a scale detection device for a water boiling utensil. The scale detection method comprises the steps as follows: obtaining the total energy consumption for heating water in the water boiling utensil to a designated temperature; calculating the unit energy consumption for heating the unit quantity of water to the designated temperature by the water boiling utensil according to the total energy consumption and the water quantity in the water boiling utensil; when the unit energy consumption is larger than or equal to a predetermined value, judging that scale exists in the water boiling utensil. By the aid of the scale detection method and the scale detection device, the scale in the water boiling utensil can be detected accurately, so that whether the scale is required to be removed or not can be judged accurately.

Description

technical field [0001] The invention relates to the technical field of water boilers, in particular to a scale detection method for water boilers and a scale detection device for water boilers. Background technique [0002] At present, water heating appliances such as electric kettles are usually provided with an electric heating element (heating pipe) at the bottom or side wall of the pot body. Heat is transferred to the water inside the jug, raising the temperature of the water to a boil or to a temperature set by the user. [0003] As the electric heating element heats the water, the calcium carbonate contained in the water will gradually accumulate and condense on the inner wall of the pot body, especially the part where the inner wall of the pot body contacts the heating pipe, forming scale. When the scale accumulates to a certain thickness, it will affect the heat transfer and reduce the effective utilization rate of electric energy into heat energy, that is, the more...

Problems solved by technology

However, since the amount of water boiled by the water boiler is different each time, and the accumulative speed of scale is also different due to the difference in water quality, therefore, only using the number of times of boiling water or the amount of boiled water as the basis for judging whether to remove scale will lead to judgment If the result is not accurate, there may be a problem that there is already a lot of scale in the water boiler, but there is still no reminder, or there is very little scale in the water boiler, but the user has been reminded to remove the scale
