Novel instant constant-temperature electric water heater

Abstract

The invention discloses a novel instant constant-temperature electric water heater. The novel instant constant-temperature electric water heater comprises an electric control module, a water heating module, a water inlet flow adjusting module and a water pressure difference safety control module; the water heating module comprises a cylindrical membrane type heater, a water inlet electricity insulation wall and a water outlet electricity insulation wall, the water inlet electricity insulation wall and the water outlet electricity insulation wall are arranged in a water channel of the membrane type heater, a spiral water channel is arranged on the outer wall of the water channel, a metal pipe is arranged outside the spiral water channel in a sleeving mode, and a membrane type heating circuit is arranged on a wall of the metal pipe in a laid mode; and the water pressure difference safety control module comprises a first plastic base, a water channel in the plastic base and a differential pressure switch, the differential pressure switch is installed on the plastic base, and a high pressure bin and a low pressure bin of the differential pressure switch communicate with a water inlet channel and a middle water channel in the plastic base respectively. The novel instant constant-temperature electric water heater can effectively solve the problems that occupied space of the electricity insulation walls is large and the electricity insulation effect is not ideal and has the advantages of being ingenious in structure, convenient to use, safe and reliable.

Description

technical field [0001] The invention relates to an electric water heater, in particular to a novel instantaneous constant temperature electric water heater. Background technique [0002] The current instant water heater temperature regulation generally uses silicon controlled silicon to adjust the input power to meet the water temperature regulation method, which has defects. When the water volume fluctuates greatly, the temperature is difficult to meet the user's requirements; Usually, some anti-electricity walls are set up for anti-electricity treatment. This type of anti-electricity wall is generally separated from the heating device, so that the anti-electricity wall will occupy the internal space of the electric water heater. Such external anti-electricity walls are all connected to the water outlet. , the anti-electric effect is lacking. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new type of instant...
