Abstract

The invention relates to an electric water heater for an instant electric water heater or an electric fireplace. The electric water heater comprises an electric water heater body, a dry burning-resistant protection temperature controller, a control device and an operation display panel, wherein the electric water heater body comprises a plurality of electric heating pipes, a water guiding pipeline, and a metal shell covering the electric heating pipes and the water guiding pipeline; a mains supply, the dry burning-resistant temperature controller, the control device and the electric heating pipes are sequentially connected. The electric water heater is characterized by also comprising a storage battery and a charger, wherein the mains supply, the charger, the storage battery, the dry burning-resistant temperature controller and the control device are sequentially connected. By adopting the structure, the electric water heater only needs to be powered by a common circuit with the mainssupply meeting the national standard, so that the defect that in the prior art, independent wiring is needed, so that the inconvenience in use is caused is overcome; the trouble that a consumer needsto carry out independent wiring is eliminated.

Description

technical field [0001] The invention relates to a device for an instant electric water heater or an electric fireplace, especially an electric water heater. Background technique [0002] In the current prior art, an electric water heater for an instant electric water heater or an electric fireplace includes an electric water heater body, a dry-burn protection temperature controller, a control device, and an operation display panel. The electric water heater body includes several electric heating tubes , the water pipe and the metal shell covering the electric heating pipe and the water pipe; the mains power supply, the anti-dry thermostat, the control device and the electric heating pipe are connected in sequence. Existing problems are: the power of the electric heating tube is large, and the diameter of the power supply line is large. When in use, it needs to be wired separately; it is inconvenient to use, which directly affects sales. Contents of the invention [0003] ...
