Stepping water boiler

Abstract

The invention relates to a stepping water boiler. The stepping water boiler comprises an electric control device, a stepping heating water liner, a steam heat exchange water liner, a heat exchange water liner, a hot water outlet and a warm boiled water outlet; the steam heat exchange water liner is arranged below the stepping heating water liner and above the heat exchange water liner; a water purifier is arranged on one side of the heat exchange water liner; the water purifier and the heat exchange water liner, the steam heat exchange water liner and the stepping heating water liner, the steam heat exchange water liner and the heat exchange water liner, as well as the heat exchange water liner and the stepping heating water liner are connected with each other by adopting water pipes; a water inlet is formed in the bottom of the stepping heating water liner; an electronic pressure relief valve is arranged at the water inlet. Boiling water is introduced into a heat exchange water pipe; the boiling water is subjected to physical cooling by using unheated water so that the unheated water becomes warm water; the drinking safety of the warm water is ensured; the boiling water and steam are utilized to exchange heat with the water which does not enter a heating liner; when the water enters the heating liner for heating, the heat energy consumption when the water is boiling is reduced, so that full utilization of steam heat energy is realized.

Description

technical field [0001] The invention relates to a water boiler, in particular to a step-by-step water boiler. 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. After the tap water is turned off and the water is boiled, turn on the faucet, and 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: since the water tank is not equipped with an insulation layer, it is difficult to boil water. After opening, the steam is steaming, and the steam is directly discharged to the outside, which greatly wastes energy. Moreover, the raw water in the water tank is mixed with boiling water, which...

[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. After the tap water is turned off and the water is boiled, turn on the faucet, and 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: since the water tank is not equipped with an insulation layer, it is difficult to boil water. After opening, the steam is steaming, and the steam is directly discharged to the outside, which is a great waste of energy. Moreover, the raw water in the water tank is mixed with boiling water, which is unhygienic and not conducive to human health.
