Description
Technical Field
The utility model relates to a water heater of electricity and gas heating, electric gas water heater or electric water heater for short.
Background
At present, two types of completely different commodities, namely an electric water heater and a gas water heater, exist all over the world, the electric water heater is an appliance for heating water and storing the water, the long-time heating is needed, and the power consumption is high; the gas water heaters all adopt atmospheric direct-injection combustion to pollute the atmosphere; at present, Chinese families must have a power supply and gas, in different areas and at different time, the price of electricity and gas is different, if one electric appliance uses electricity or gas, the electric appliance can be freely selected, and the market demand is better met; the application of the patent provides a new structure, the heating mode of electricity and gas is adopted, the using condition and the installation mode are completely the same as those of the existing gas water heater, and both electricity connection and gas connection are required; the electric water heater and the gas water heater are integrated into a whole, and the electric water heater can gradually replace the electric water heater.
SUMMERY OF THE UTILITY MODEL
The utility model aims to improve the prior various gas water heaters, and provides an electric gas water heater heated by electricity and gas, which realizes instant heating all year round and realizes no current limiting and hot water discharging, 2/3 time all year round and zero discharge; the electric water heater consists of casing, heat exchange water container, combustor, gas valve, igniting and flameout protector, electrothermal pipe, water switch or water flow sensor.
The technical measure of the utility model is that a heat exchanger 11 is arranged in a shell 1, an electric heating pipe is arranged on a hot water outlet pipeline or a water inlet pipeline of the heat exchanger, the electric heating pipe is a thin film electric heating pipe, an insulating layer is printed on the outer surface of a metal pipe, and the electric heating pipe is made by high-temperature sintering, and water circulates in the pipe; or the aluminum electric heating pipe is provided with a water flow channel outside the metal electric heating pipe, and the metal electric heating pipe are cast into a whole by melting aluminum metal and are heated 3-2 in a water-proof way; a metal or nonmetal electric heating tube 3-1 is arranged in the water container 2; also comprises a burner or fire grate 4, a gas mixing and combustion chamber 12 and an ignition and flameout protection device 9; a water switch or a water flow sensor 8 is arranged on the water inlet pipeline, and the water flowing through the water inlet pipeline can be heated immediately when the water inlet pipeline is connected; the control button can select electricity or gas, or electricity and gas work simultaneously when the electricity and gas are connected.
In summer or spring and autumn, the water switch or the water flow sensor is started, the electric heating pipe is connected to heat the flowing water instantly, and electricity and gas are required to be simultaneously connected only when the temperature of tap water is extremely low in winter; therefore, in one year, electricity is used in summer, spring and autumn, and the emission is 2/3 time '0' all the year; when two kinds of energy are used, the power line is thin for users in families, and the power line is also suitable for users without gas pipelines; meanwhile, the user can use electricity or gas in summer, spring and autumn, and can select the electricity or gas by himself.
The utility model has the advantages that the electric water heater and the gas water heater are integrated, namely, one water heater can simultaneously use electricity and gas for heating, mainly uses electricity, has low power consumption, uses gas for auxiliary heating in winter, or conversely, uses electricity for auxiliary heating in a region with low gas price; the difficulty that the hot water of the electric water heater is insufficient in winter is fundamentally solved.
Drawings
FIG. 1 is a schematic diagram of an electric water heater; an electric heating pipe is arranged in the water outlet pipeline;
fig. 2 is a structural view of an electric water heater having a water container above a heat exchanger and an electric heating tube therein.
Detailed Description
The following description is made with reference to the accompanying drawings, in which, a shell 1, a water container 2, an electric heating tube including a thin film electric heating tube or an aluminum electric heating tube 3-2, a metallic or non-metallic electric heating tube 3-1 in the water container, a burner or fire grate 4, a water inlet tube (or port) 6, a water outlet tube (or port) 7, a water switch or water flow sensor 8, an ignition and flameout protection device 9, a gas valve 10, a heat exchanger 11, a gas mixing and combustion chamber 12, water 13, a gas inlet 14, a flue 15, a housing 16, a control button 17, a temperature limit switch 19, a three-way water mixing valve 33, a domestic water point 34, a pressure relief and water outlet 35, a tap water tube 36,
FIG. 1 is a schematic structural view of an electric water heater, wherein a thin-film electric heating tube or an aluminum electric heating tube is mounted at a hot water outlet of a heat exchanger, a water container 2 is arranged above the heat exchanger in FIG. 2, one or more groups of electric heating tubes are mounted in the water container, the electric heating tubes are metal electric heating tubes or non-metal electric heating tubes, when the non-metal electric heating tubes are adopted, the outer metal or non-metal sleeves are isolated from water, the sleeves are connected with the water container in a sealing manner, when a water switch or a water flow sensor is connected to drain water, the electric heating tubes are automatically connected, only in winter, the electric water heater or the gas heater or the electric water heater and the; if summer spring autumn, start gas or gas and electricity start simultaneously, also be in this patent protection.
The structure is suitable for the existing gas water heaters of any type, any variety and any specification, only the electric heating pipe is added, the electric heating pipe and the gas heating are integrated, the electricity consumption is only about 3KW in summer, spring and autumn, and the gas consumption is reduced by 40% in winter; the cheap gas area only uses gas, and the electricity is used for assisting in winter, and the functions are the same.
