Abstract

The invention discloses an instantaneous electric water heater with a non-metallic pipe inner wall plated with silicon dioxide heating elements. The instantaneous electric water heater comprises a shell, water tanks, electrical heated pipes, a water inlet pipe, a water outlet pipe, a water flow switch, a gear switch and the like; the water flow switch is of a water flow pushing type structure and is composed of a water flow switch main body, a cover plate, a sealing piece, a pushing piece, a spring or a leaf spring, an installation cover plate, a microswitch, stationary contacts, a movable contact, terminals and a pushing pin of the microswitch; a water inlet channel and a water outlet channel are separated by the cover plate instead of directly communicating with each other; when water flows, a circuit is connected, and when the water does not flow, the circuit is disconnected; the water flow switch and the gear switch need to work in a matched mode; and when water in the water tanks needs to be preheated, a preheating switch is pressed. Heating is conducted in the mode that the non-metallic pipe inner wall is plated with the silicon dioxide heating elements, and a metal heating pipe can be adopted at the same time.

Description

technical field [0001] The invention relates to a fast-heating electric water heater with a silicon dioxide heating element coated on the inner wall of a non-metallic tube. Background technique [0002] Patent Application Publication No. CN104236106A discloses "Electric Water Heater Controlled by Water Flow Switch", which mainly relates to storage water heaters. Although it also involves fast heating water heaters, the expression is not perfect and there are still deficiencies. This patent application provides a new structure . Contents of the invention [0003] The present invention is improved on the basis of CN104236106A, and after improvement, it is a fast-heating electric water heater with a silicon dioxide heating element plated on the inner wall of a non-metallic tube. Shell 17, physical water resistance 22, water tank pressure control part 23, etc.; the water flow switch 20 is composed of a main body 1, a cover plate 2, a seal 3 and a pusher 4, a spring or spring ...
