High-hot-water-output antibacterial water heater

Abstract

The invention discloses a high-hot-water-output antibacterial water heater. The high-hot-water-output antibacterial water heater comprises an outer shell, an inner container arranged in the outer shell, a water inlet assembly and a water outlet tube, wherein the water inlet assembly and the water outlet tube are arranged on the inner container. The water inlet assembly comprises a tube body and a flow guide part which are arranged in a concentric manner. A sealing cover is arranged at one end of the tube body. Water outlet parts are arranged on the side wall of the tube body. The flow guide part comprises a support and a plurality of flow guide fins which are arranged on the support and correspond to the water outlet parts in position. Compared with the prior art, the high-hot-water-output antibacterial water heater has the beneficial effects that the water inlet assembly is simple in structure, small in part number and convenient to assemble; and in the process that cold water flows through the water inlet assembly to enter the inner container, the cold water can be slowly and smoothly injected into the inner container through the water inlet assembly under the condition that the existing flow of the injected cold water is kept, the cold water is accumulated at the lower portion of the inner container, the hot water output rate of the high-hot-water-output antibacterial water heater is greatly increased accordingly, a user can use more hot water, and the energy saving effect is obvious.

Description

technical field [0001] The invention relates to an electric water heater, in particular to an antibacterial water heater with high hot water output. Background technique [0002] Since the implementation of the energy efficiency mandatory requirements of GB21519-2008 "Energy Efficiency Limits and Energy Efficiency Grades for Water Storage Electric Water Heaters" of existing water storage electric water heaters, various enterprises have improved their indicators through various technologies. The energy efficiency limit value and energy efficiency grade of water storage electric water heater mainly assess the 24-hour inherent loss and hot water output rate, and mark the energy efficiency according to the lowest item. Among them, the technical way to increase the hot water output rate is to minimize the turbulent flow of the water heater to cause the rapid mixing of cold and hot water inside the water heater, so that the water level in the upper part of the water heater will dr...

Problems solved by technology

[0003] The first one improves the hot water output rate by improving the diameter of the water inlet pipe and using a thicker pipe diameter for buffering. The structure of the electric wall is generally only 3 / 4, and the improvement margin is greatly limited

[0004] The second is to adjust the size and direction of the water flow by improving the diameter or opening size of the drainage hole of the water inlet pipe. After years of improvement, the effect has reached the limit, especially when the water flow rate is very high, the improvement effect has dropped significantly.

Although this type of water heater improves the hot water output rate, when the water consumption is large, that is, when the water flow in the water inlet pipe is fast, the flow guide member has a large area of ​​obstruction to the water flow, which affects the water outlet efficiency of the water heater.
