Electric water heater with water outlet flow rapid changing function

Abstract

The invention discloses an electric water heater with a water outlet flow rapid changing function. The electric water heater comprises a liner, electric heating tubes, a water inlet tube, a water outlet tube and a control panel. A water outlet of the liner communicates with the water outlet tube; the water inlet tube communicates with a water inlet of the liner through a water inlet control part;the water inlet control part comprises a shell; a water inlet channel and a water outlet channel are formed in the shell, and the water inlet channel communicates with the water outlet channel througha first water path and a second water path which are connected in parallel; a first electromagnetic gate valve and a first flow stabilizer are mounted on the first water path, a second electromagnetic gate valve and a second flow stabilizer are mounted on the second water path, and a third flow stabilizer is mounted on the water outlet channel; and the water outlet flow of the third flow stabilizer is larger than that of the second flow stabilizer, the water outlet flow of the second flow stabilizer is larger than that of the first flow stabilizer, and the sum of the water outlet flow of thefirst flow stabilizer and the water outlet flow of the second flow stabilizer is larger than the water outlet flow of the third flow stabilizer. The water outlet flow of the water outlet tube can be changed rapidly, each kind of water outlet flow is stable, and thus using is convenient.

Description

technical field [0001] The invention relates to the technical field of electric water heater manufacturing, in particular to an electric water heater capable of rapidly changing the water flow rate. Background technique [0002] Traditional quick-heating or heat-storage electric water heaters usually need to use an external water mixing valve to change the outlet water flow. However, adjusting the outlet water flow through the water mixing valve is troublesome to adjust, and the outlet water temperature will change with the outlet water flow. Changes have changed and are more troublesome to use. At present, some high-end fast-heating electric water heaters use flow valves in conjunction with stepping motors and control boards to adjust the water flow. Although this kind of fast-heating electric water heater is more convenient to use, its manufacturing cost is high and maintenance is difficult. Larger and difficult to popularize.
