Water heater and pipe electric heating device for water heater

Abstract

The invention relates to a heater and a pipeline electric heating device for the heater. The pipeline electric heating device is arranged at a water outlet pipe of the heater, is used for further heating effluent water of the heater, and comprises a heating pipe and a spiral flow guiding rod, wherein the heating pipe is connected with the water outlet pipe of the heater, and is used for heating water flowing through the heating pipe; the spiral flow guiding rod is arranged in the pipe cavity of the heating pipe, is axially arranged along the heating pipe, and is provided with a spiral part abutted against the inner wall of the heating pipe, so that a spiral flow channel is jointly defined by the spiral part and the inner wall of the heating pipe; and the flowing water spirally flows through the heating pipe, so that the heat exchanging area is enlarged. The pipeline electric heating device for the heater disclosed by the invention can be used for further heating the water flowing inwards from the water outlet pipe of the heater, so that the instant heating performance of the heater is realized, and the heating efficiency of the heater is improved.

Description

technical field [0001] The invention relates to a water heater, in particular to a water heater and a pipeline electric heating device for the water heater. Background technique [0002] The existing water heater mainly includes a water tank, a heating device, a pipeline and a valve. In order to improve the instant heating performance of the water heater, a three-way mixing valve is generally installed in the water outlet pipeline of the water heater, and the tap water is mixed with the hot water in the water tank to provide users with hot water of suitable temperature. [0003] This kind of water heater generally uses an electric heating rod to go deep into the water tank of the water heater, and the water in the water tank is heated by the electric heating rod to provide hot water for the three-way mixing valve. inconvenience. In addition, due to the large amount of water in the water tank, the heating efficiency of the electric heating rod is low, and the waiting time i...

AI Technical Summary

Problems solved by technology

[0003] This type of water heater generally uses electric heating rods to go deep into the water tank of the water heater, heat the water in the water tank through the electric heating rods, and provide hot water for the three-way mixing valve, resulting in a large volume of the required water tank, which takes up a large space and brings troubles to the user. Inconvenience

Moreover, due to the large amount of water in the water tank, the heating efficiency of the electric heating rod is low, and the waiting time is long, which brings certain troubles to the user
