Description

Electric water heater that calculates heating time data based on the water temperature in the barrel

This creation is related to electric water heaters, especially an electric water heater that calculates heating time data based on the water temperature in the barrel.

Conventional electric water heaters are mainly preset with a predetermined temperature. When the actual temperature of the electric water heater does not reach the predetermined temperature, the electric water heater will start heating, and stop heating when the actual temperature reaches the predetermined temperature.

However, current electric water heaters do not have the function of calculating the time data required for the actual temperature to rise to the predetermined temperature. The applicant believes that if an electric water heater is developed that can calculate the time required for the actual temperature to rise to the predetermined temperature, it can provide time. The data is for reference (for example: when the user can know how long the electric water heater can be used normally, the user can effectively use this waiting time without waiting), so if it can provide a way to calculate the actual temperature rise Electric water heaters with data on the time required to reach a predetermined temperature can improve the convenience of use.

The main purpose of this creation is to provide an electric water heater that calculates heating time data based on the water temperature in the barrel, which can obtain data on the time required for the electric water heater to heat to a preset temperature, which can improve the convenience of use.

The calculation unit sets a preset temperature. The calculation unit receives the first temperature and the second temperature by the first sensor. When the first temperature or the second temperature is If the second temperature or both are less than the preset temperature, the control unit controls the heater to start, and the calculation unit uses an arithmetic logic to calculate the first temperature and the second temperature, and then the heater stores the temperature When the water in the bucket is heated to the preset temperature, when the first temperature or the second temperature or both are greater than or equal to the preset temperature, the control unit controls the heater not to start.

In this way, the electric water heater provided by this creation calculates the heating time data according to the water temperature in the barrel, which can obtain the time data required for the electric water heater to heat to the preset temperature, which can improve the convenience of use. .

In addition, in other preferred embodiments, the calculation unit 51 calculates the time data for the heater 30 to heat the water in the water storage bucket 20 to the preset temperature, which can also be applied to data statistics, not necessarily displayed on The display panel is for the user to view, so the calculation unit 51 calculates the usage of the time data for the heater 30 to heat the water in the water storage bucket 20 to the preset temperature, which is not limited by this preferred embodiment.

In this preferred embodiment, a second sensor 60 is further included. The second sensor 60 is disposed in the water storage bucket 20 and is electrically connected to the control chip 50. The second sensor 60 A third temperature and a fourth temperature are measured. When the third temperature and the fourth temperature are less than the preset temperature, the control unit 53 controls the heater 30 to start, and the calculation unit 51 uses the arithmetic logic Calculate the third temperature and the fourth temperature, the calculation logic is based on the time difference and temperature difference between the third temperature and the fourth temperature, and the heater 30 is calculated to heat the water in the water storage bucket 20 based on the principle of heat calculation The time data of the preset temperature is prepared. When the third temperature and the fourth temperature are equal to the preset temperature, the control unit 53 controls the heater 30 not to start, thereby improving the calculation of the water in the water storage bucket 20 The accuracy of the time data when the temperature rises to the predetermined temperature.
