Problems solved by technology
The water temperature distribution and water flow in the water heater are greatly affected by factors such as the shape of the container, the position of the water inlet and outlet, and the flow rate. The inner tank volume and size of the water heater are different, and the installation positions of the water inlet and outlet pipes and heating pipes are different. Differences will have a great impact on the water temperature distribution and water flow in the tank, reducing the accuracy of the calculation results

The invention belongs to the technical field of household appliances, and discloses a method used for calculating remaining bathing time of an electric water heater. The electric water heater comprises a total water inlet pipe and a total water outlet pipe, and further comprises an inner container provided with a first water inlet pipe, a first water outlet pipe and an electric water heater body,the total water inlet pipe communicates with the first water inlet pipe, and the total water inlet pipe and the first water outlet pipe communicate with total water outlet pipe through a first water mixing valve. The method comprises the steps that at the starting moment when a user uses the electric water heater, the instant water temperature T1 of water in the inner container is detected; in theprocess that the user uses the electric water heater, water temperature data in the total water inlet pipe are collected multiple times, the water temperature T2 in the total water inlet pipe is calculated, the power consumption P of the electric water heater is detected periodically, and the remaining bathing time t of the electric water heater is calculated. The embodiment of the invention further discloses the electric water heater.
Description
technical field [0001] The invention relates to the technical field of household appliances, in particular to a method for calculating the remaining bathing time of an electric water heater and an electric water heater. Background technique [0002] Storage-type electric water heaters have entered thousands of households, and users hope to know the amount of hot water remaining in the electric water heater during bathing with the electric water heater. An existing method for detecting the amount of hot water in the inner tank of an electric water heater is to install a water flow sensor on the water inlet pipe or outlet pipe of the inner tank of the water heater, and the control system calculates the size of the water outlet flow, and the water flow is multiplied by time to calculate Get the actual flow of water flowing into the inner tank of the electric water heater, and then use the formula to convert to get the remaining hot water in the inner tank. During the user's ba...
