Method and apparatus for reminding cleaning of electric heater

Abstract

The invention discloses a method for prompting the cleaning of an electric heating apparatus. The method comprises the steps as follows: during the process of heating liquid, the temperature of the liquid in a vessel is measured by a preset time interval and the actual average temperature variation quantity of the liquid is calculated; the actual average temperature variation quantity is compared with a preset reference value, if the actual average temperature variation quantity reaches or is larger than the reference value, a cleaning prompt is sent; the reference value is determined according to the average temperature variation quantity of the pure liquid or the liquid with preset impurity quantity. The invention also provides a corresponding cleaning prompting device of the electric heating apparatus. The embodiment of the invention realizes that the cleaning prompt generates automatically according to the impurity content in a heating vessel, thus being convenient and accurate.

Description

technical field [0001] The invention relates to the field of small household appliances, in particular to a cleaning prompt method and device for an electric heating appliance. Background technique [0002] Existing electric heaters currently on the market for heating drinking water, such as electric kettles, coffee pots or similar devices, are generally equipped with temperature sensors to detect and control the temperature of the water, but the electric heaters have been used for a long time. After a long period of use, residues such as impurities or scale will be produced in the heating vessel, which will adhere to the inner wall of the heating vessel, which will not only affect hygiene and health, but also affect the water flow and function of electric heating appliances. However, in the prior art, it is only cumbersome and inaccurate to determine whether the heating vessel needs to be cleaned only through the user's visual inspection or empirical judgment.

[0002] Existing electric heating appliances currently on the market for heating drinking water, such as electric kettles, coffee pots or similar devices, are generally equipped with temperature sensors to detect and control the temperature of water, but the electric heating appliances have passed through a long period of time. After a long period of use, residues such as impurities or scale will be produced in the heating vessel, which will adhere to the inner wall of the heating vessel, which will not only affect hygiene and health, but also affect the water flow and function of electric heating appliances

However, in the prior art, it is only cumbersome and inaccurate to determine whether the heating vessel needs to be cleaned through visual inspection or empirical judgment by the user.
