A vertical instantaneous electric water heater controlled through a water flow switch and provided with a metal electric heating pipe for heating comprises an outer shell, a water tank, the electric heating pipe, a water inlet pipe, a water outlet pipe, the water flow switch, a gear switch and the like, wherein the water flow switch is of a water flow pushing type structure and is composed of a main body, a covering plate, a sealing part, a pushing part, a spring or a leaf spring, an installation covering plate, a micro switch, a static contract, a movable contact, a terminal and a pushing pin of the micro switch; and a water inlet passage and a water outlet passage do not communicate directly but are separated by the covering plate. When water flows, a circuit is connected, and when water does not flow, the circuit is disconnected. The water flow switch and the gear switch are matched to work, and a preheating switch is pressed when water in the water tank needs to be preheated.
Description
technical field [0001] The invention relates to a vertical fast-heating electric water heater heated by a metal electric heating tube controlled by a water flow switch. 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 improves on the basis of CN104236106A, and the electric water heater heated by the vertical fast-heating metal electric heating tube controlled by the improved water flow switch consists of a water flow switch 20, a water tank 12, an electric heating tube 13, a water inlet pipe 14, a water outlet pipe 15, and a shell 17. Physical water resistance 22, water tank pressure control part 23, etc.; the...
