The invention discloses an energy-saving safe electric water heater or a drinking water device, which comprises a controller, a transformer, at least one low-voltage heating fuse and a water pipe, wherein one end of the water pipe is provided with a water inlet, the other end of the water pipe is provided with a water outlet, and a tap water pipe is connected with the water inlet; a mains supply is electrically connected with the input end of the transformer; the transformer reduces the mains supply of 220V to a safe voltage of below 30V; the output end of the transformer is electrically connected with the input end of the controller, and the output end of the controller is electrically connected with the low-voltage heating fuse through a cable; a water isolation pipe made of a material with good heat conduction performance is arranged in the water pipe, the low-voltage heating fuse is arranged in the water isolation pipe, and the water isolation pipe is arranged in the water pipe; and the transformer reduces the mains supply voltage to 30V, and then the mains supply voltage is connected with the low-voltage heating fuse so that the low-voltage heating fuse works in a safe voltage range, and the human body is not injured even if the heating fuse leaks current or the outer wall of the water pipe is overheated.
Description
technical field [0001] The invention relates to the technical field of water heating devices, in particular to an energy-saving and safe electric water heater and a drinking water device. Background technique [0002] In the prior art, the electric water heater or the pure water machine with heating function directly use the mains power supply. After the power supply passes through the heating wire, the heating wire heats up, and the heating wire heats the water again, so that the water reaches a temperature suitable for bathing or Suitable temperature for drinking. However, because the electric water heater directly uses the mains power supply, as we all know, the current standard of the mains voltage in our country is 220V. If people are directly exposed to the 220V power supply, people's bodies will be injured, and in severe cases, people will be electrocuted. died. At present, electric water heaters have entered people's homes, because electric water heaters directly u...
