Anti-cooling electric water heater

Abstract

The invention discloses an anti-cooling electric water heater. The anti-cooling electric water heater comprises a shell, a mounting groove is formed in the inner bottom of the shell, a heating block is arranged on the inner side of the mounting groove, a water inlet and a water outlet are formed in the side wall of the shell, and a sliding groove is formed in the water inlet. The design is reasonable, by arranging a driving assembly, when water flows out of the water outlet, waterflow impacts a fixing plate to drive a first rotating shaft to rotate, the first rotating shaft enables a first protrusion and a second protrusion to continuously rub under the transmission action of a first bevel gear, a second bevel gear and a second rotating shaft, then the temperature of low-boiling-point evaporated liquor rises, the low-boiling-point evaporated liquor is heated and gasified, the air pressure of an inner cavity is increased to drive a piston and a first magnet to move upwards, and a second magnet drives a limiting block to block the water inlet under the repulsive force effect of the first magnet, so that the purpose that the water inlet is temporarily blocked after water flows out is achieved.

Description

technical field [0001] The invention relates to the technical field of electric water heaters, in particular to an electric water heater with cooling prevention. Background technique [0002] An electric water heater refers to a device that generates a large amount of heat after the heating block is energized, and transfers this heat to the water to increase the temperature of the cold water into hot water within a certain period of time. [0003] When people use hot water, cold water will be continuously added, and the amount of water injected is the same as the amount of water flowing out when using water. Synchronous heating, so that the water temperature will not drop too low, but as more and more hot water is used, the proportion of cold water will increase, and the speed of water heating is mostly slower than the speed of use. When the remaining amount accounts for less than 1 / 2 of the total water amount, the water temperature after mixing the remaining hot water and ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the following shortcomings in the prior art. As hot water is used more and more, the proportion of cold water will increase, and the speed of water heating is mostly slower than the speed of use. When the water accounts for a small part, the temperature of these mixed water is not enough for people to use, so there is a situation of inconvenience in use, and a kind of anti-cooling electric water heater is proposed
