Description

Technical Field

[0001] The utility model relates to the technical field of step-by-step water boilers, in particular to a program-controlled variable-temperature step-by-step water boiler. Background Art

[0002] Traditional constant temperature and quantitative water boilers usually use a direct water addition method to set the temperature. This method not only has large temperature fluctuations and poor stability, but also makes it difficult to meet the user's high requirements for precise temperature control. At the same time, in terms of quantitative water output, traditional water boilers also face the challenge of low precision and cannot accurately meet the user's drinking volume needs. In order to solve the above technical problems, those skilled in the art continue to explore and innovate, trying to find a high-performance water boiler that can simultaneously achieve precise temperature control and quantitative water output. For example, in Chinese patent CN207963131U, an intelligent water boiling device with a hot water heat recovery control function is disclosed. The device controls the on and off of the electromagnetic flow valve through a single-chip microcomputer, thereby accurately controlling the flow through the electromagnetic flow valve, and realizing the output of multiple water qualities to meet the diverse needs of students' daily water. However, the constant temperature and quantitative water boiler of the above scheme uses a direct water addition method to set the temperature.
