Abstract
Description
Technical Field
[0001] This application relates to the field of electric water heater technology, and specifically to an electric water heater that heats water evenly. Background Technology
[0002] Traditional electric water heaters, due to the lower density of hot water compared to cold water, exhibit significant hot water stratification within the tank: hot water accumulates at the top, while cold water settles at the bottom. When a user uses hot water, the outlet pipe first discharges the hot water from the top layer, followed by the gradually rising cold water from the bottom, resulting in a fluctuating water temperature – initially scalding hot, then cooling. This unstable temperature output necessitates frequent, manual adjustments to the mixing valve to maintain a comfortable water temperature, especially during showering. This inconvenience significantly impacts ease of use and user experience. Utility Model Content
[0003] To address the problem of uneven heat distribution in the inner tank of existing electric water heaters, this application provides an electric water heater with more uniform heating. The specific technical solution of this application is as follows:
[0004] An electric water heater with uniform heating includes: a water heater inner tank, a water storage cavity provided in the water heater inner tank, an outlet pipe and an inlet pipe respectively provided on the water heater inner tank for connecting the water storage cavity and the outside of the water heater inner tank, the outlet pipe opening in the water storage cavity is located at the upper end of the water storage cavity, the inlet pipe opening in the water storage cavity is located at the lower end of the water storage cavity, a rotating bracket is provided above the inlet pipe and outlet pipe openings in the water storage cavity, a propeller is provided in the rotating bracket, and a heating component extending into the water storage cavity is provided on one side of the water heater inner tank.
[0005] Furthermore, the outer wall of the inlet and outlet pipes located in the water storage cavity is provided with a first screw hole, and the rotating bracket is provided with a second screw hole that mates with the first screw hole.
[0006] Furthermore, a rotating pin is provided at the bottom of the rotating bracket, and the propeller is mounted on the rotating pin.
[0007] Furthermore, the top of the rotating pin is provided with a threaded portion.
[0008] Furthermore, the rotating bracket, propeller, and rotating pin are made of plastic.
[0009] Furthermore, the heating assembly includes two heaters arranged vertically.
[0010] Furthermore, the inner tank of the water heater has a recessed groove on the opposite side from the heating component, which is recessed into the water storage chamber, and a temperature sensor is installed in the groove.
[0011] This invention effectively solves the problem of water temperature stratification by introducing a passive stirring mechanism at the inlet and outlet of the inner tank, resulting in the following significant technical effects:
[0012] To promote uniform water temperature and achieve stable water output: This invention features propellers installed above the inlet and outlet pipes. When cold water is injected through the bottom inlet pipe or hot water is discharged through the top outlet pipe, the water flow naturally drives the propellers to rotate. The rotating propellers effectively agitate the water in the inner tank, breaking up the original stratification of hot and cold water, promoting mixing, and resulting in a more uniform water temperature throughout the inner tank. Therefore, users can obtain consistently hot water throughout the entire water usage process, eliminating the need for frequent temperature adjustments and greatly improving comfort and convenience.
[0013] Passive drive, safe and energy-saving: The propeller's rotation relies entirely on the power of the water flow itself, requiring no external electricity or complex transmission mechanisms. This purely mechanical passive stirring method offers high safety performance, eliminates electrical risks, and generates no additional energy consumption, achieving energy savings while improving performance.
[0014] Simple structure and easy to implement: This solution only adds a rotating bracket and a propeller to the existing pipeline structure. The structure is simple and reliable, the modification cost is low, and it is easy to apply and promote on existing products, which can effectively improve the overall performance of electric water heaters.
