Instant water heater

Abstract

Provided is an instant water heater. The instant water heater includes a housing, a water inlet pipe, a water outlet pipe, a mounting member, and an electric controller. The housing has a heating container inside. The heating container includes a cap and a water tank detachably connected to the cap. A heating pipe is disposed within the water tank. The water inlet pipe is in communication with a first side of the cap. The water outlet pipe is in communication with a second side of the cap. The water inlet pipe and the water outlet pipe are connected to two sides of the housing, respectively. The mounting member is configured for securing the water tank to the housing. The electric controller is configured for controlling the heating pipe. By providing stability of the heating container, the provided instant water heater can optimize distribution and installation of components.
