Description

Technical Field

[0001] This utility model relates to a storage-type electric water heater. Background Technology

[0002] The existing technology, Chinese patent 201721114857.1, describes an electric water heater with a high hot water output rate, including an inner tank, an inlet pipe, and a heating element. It also includes a baffle plate at the bottom of the inner tank, with the outlet of the inlet pipe located below the baffle plate. The heating element is positioned on both sides of the baffle plate, near the bottom of the inner tank. This invention, by using a baffle plate and placing the outlet of the inlet pipe below it, reduces the flow rate of cold water entering the inner tank, preventing damage to the stratified hot water in a static state. This prevents mixing of cold and hot water in the inner tank, improving the hot water output rate and reducing energy consumption. By positioning the heating element on both sides of the baffle plate near the bottom of the inner tank, sufficient convection between the hot and cold water in the inner tank is achieved, reducing the temperature difference between different locations within the tank and ensuring that as much water as possible is heated. This results in a more uniform overall temperature of the water in the inner tank, meeting the user's hot water usage requirements. However, a problem exists: the ends of the cold water inlet pipe and the hot water outlet pipe are exposed, posing a risk of loosening during handling and transportation. Utility Model Content
