Double energy collection stepping water boiler

Abstract

The invention discloses a double energy collection stepping water boiler which comprises a shell, an electric control device, a water inlet solenoid valve, high and low water level electrodes and a heat energy recoverer, wherein a water tank is arranged in the shell, and the bottom and side walls of the water tank are respectively provided with a thermal insulation layer. The invention is characterized in that the top of the water tank is additionally provided with a thermal insulation layer; the high and low water level electrodes are installed in the water tank; the upper part of the water tank is provided with a steam outlet; the heat energy recoverer is composed of a heat exchange body formed by sheathing an outer tube on an inner tube; one end of the inner tube is communicated with the steam outlet of the water tank, and the other end extends out of the shell through a guide tube; one end of the outer tube is communicated with a water inlet on the bottom of the water tank, and the other end is connected with a water supply pipeline on the shell; and the water inlet solenoid valve is arranged on the water supply pipeline and electrically connected with the high and low water level electrodes and the electric control device. The periphery of the entire water tank (including bottom, top and side walls) is provided with a thermal insulation layer for sealing and thermal insulation, and the water boiler recovers steam heat by cooperating with the heat energy recoverer, thereby realizing the effect of double energy collection. In addition, the water level electrodes are used instead of floating ball water level with poor stability and reliability, thereby obviously enhancing the stability and reliability of the overall system of the water boiler.

Description

technical field [0001] The present invention relates to the technical field of water boilers, in particular to a dual energy-gathering step-by-step water boiler that can significantly save electric energy and effectively improve heating efficiency. Background technique [0002] The ordinary water boiler in the prior art is provided with a water tank in the housing, and the bottom, top and side walls of the water tank are generally not provided with an insulating layer. The tap water enters the water tank from the upper part through the float valve. Turn off the tap water, after the water is boiled, turn on the faucet, as much boiling water flows out, the water tank will inject as much tap water from the upper part to form a mixture of raw water; the water boiler with this structure has the following disadvantages: (1) because the water tank is not provided with an insulation layer , After the water is boiled, the steam will rise, and the steam will be directly discharged to ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcomings of energy waste, low thermal efficiency, and float ball control water level in the above-mentioned prior art, and provide a simple and reasonable structure, which can obviously save electric energy and improve heating efficiency by recycling steam. And effectively improve the stability and reliability of the dual-energy stepping water boiler
