Energy-saving water heater

Abstract

The invention discloses an energy-saving water heater which comprises a solar energy water heater, an instantaneous heating electric heater, a temperature sensor and a water heater electric control unit, wherein the energy-saving water heater also comprises an electric control water quantity control valve and a water heater electric control unit (ECU), wherein the instantaneous heating electric heater is provided with two water inlets and a water outlet, one water inlet is connected to the solar energy water heater; the water heater electric control unit is connected wit the instantaneous heating electric heater, the temperature sensor and the electric control water quantity control valve, and is used for processing a signal transmitted by the temperature sensor, controlling the working states of the control valve and the electric heater, and regulating the water quantity and the water temperature. According to the energy-saving water heater, the traditional household water heater is improved and characteristics of the solar energy water heater and the instantaneous heating electric heater are saved, thus a large quantity of electric energy and water resources are saved; meanwhile, the energy-saving water heater has the advantages of simple structure, low required cost and convenience for operation.

Description

technical field [0001] The invention belongs to the technical field of water heaters, and in particular relates to an energy-saving water heater which is convenient for household use. Background technique [0002] In the current prior art, domestic water heaters are mainly divided into solar water heaters, water storage electric water heaters, gas water heaters and instant electric heaters. Among them, solar water heaters can effectively use solar energy to heat tap water and save a lot of electric energy, but they need to have a sunny outdoor space to arrange solar collectors, and the pipeline layout is long, which is easily affected by the weather. In cloudy days or when there is no sunlight at night , the solar water heater cannot heat the tap water, and the location where the solar water heater is installed is far away from the water place. waste of water resources.

Problems solved by technology

Among them, solar water heaters can effectively use solar energy to heat tap water and save a lot of electric energy, but they need a sunny outdoor space to arrange solar collectors, and the pipeline layout is long, which is easily affected by the weather. In cloudy days or when there is no sunlight at night , the solar water heater cannot heat the tap water, and the location where the solar water heater is installed is far away from the water place. waste of water

The storage type electric water heater needs to be turned on in advance when it is in use, which cannot meet the requirements of instant heat and use, and it will waste electric energy if it is turned on for a long time for preheating.

Gas water heaters can meet the requirements of instant use, but due to geographical limitations, they can only be installed in the kitchen. If the kitchen is too far away from the bathroom, it is not conducive to the layout and use of pipelines. At the same time, if the environment is closed, it is easy to cause personnel Gas poisoning, and gas water heaters are prone to heat instability

The instant electric heater can be used immediately without geographical restrictions, but it has a large power and consumes a lot of electricity
