Instant electric water heater

Abstract

The invention discloses an instant electric water heater; a vertical shunting clapboard is arranged in the middle part between the front and back sides of a box body to form a first cavity and a second cavity, a group of stream guidance holes are arranged at top part of the shunting clapboard, a group of stainless steel thermal energy pipes are uniformly distributed in the first cavity and the second cavity horizontally or vertically, and ports of the stainless steel thermal energy pipes are welded with the corresponding side plates of a box body in a penetrating way, a group of carbon fiber far infrared heating tubes are respectively arranged in the group of the stainless steel thermal energy pipes and are fixed by fixed clamping plates, a power supply input end of each carbon fiber far infrared heating tube body is electrically connected with an automatic thermostat by a wiring groove circuit board. the instant electric water heater has rapid heating, low power consumption, high hotwater yield, high electric-heating conversion efficiency, good safety and long service life and is energy saving and environmental protection.

Description

technical field [0001] The invention relates to the technical field of electric water heaters, in particular to an instant electric water heater. Background technique [0002] Current water heaters are divided into gas-fired water heaters, storage-type electric water heaters, instant electric water heaters and solar water heaters in terms of application methods. Gas-fired water heaters are heated by gas, with a wide range of applications, fast heating, large water output, stable water temperature, less scaling, and a small footprint, not controlled by water volume. However, toxic gases will be emitted due to insufficient combustion during use , it is easy to cause safety accidents and form a vicious greenhouse effect; and the starting water pressure is high, and some high-rise residents cannot start without a booster pump; the installation is inconvenient, and holes need to be drilled on the wall to install exhaust fans, etc. ; Different types of gas have different burner s...

Problems solved by technology

Gas-fired water heaters are heated by gas, with a wide range of applications, fast heating, large water output, stable water temperature, less scaling, and a small footprint, not controlled by water volume. However, toxic gases will be emitted due to insufficient combustion during use , it is easy to cause safety accidents and form a vicious greenhouse effect; and the starting water pressure is high, and some high-rise residents cannot start without a booster pump; the installation is inconvenient, and holes need to be drilled on the wall to install exhaust fans, etc. ; Different types of gas have different burner shapes, nozzle sizes, and gas channel cross-sectional areas; and the price of natural gas continues to rise, which also increases the cost of use

Water storage electric water heaters can adapt to any weather changes, but they must be powered on for a long time to supply hot water with a large flow, and they are bulky, occupy a large amount of indoor space, are prone to scale, and waste a lot of electric energy

Although the existing instant electric water heater has a built-in anode magnesium rod descaling device, which solves the problem that the product is easy to scale, but the anode magnesium rod must be replaced every two years, which brings trouble to maintenance; instant electric water heater Relatively speaking, the volume is small, the space is small, and it is more beautiful, but the power consumption is very large. Generally, it needs more than 10KW to have instant heating effect. It has high requirements for interior decoration electrical materials and consumes a lot of consumables. The use of other high-power electrical appliances in the home is affected, and the safety of electricity use needs special treatment; and the solar water heater with auxiliary electric heating device is mainly based on solar heating, supplemented by electric heating. It is used all year round, but the installation is complicated, which may affect the appearance and quality of the housing and the appearance of the city. Maintenance is more troublesome. Because solar water heaters are installed outdoors, most of them are on the roof, so compared with electric water heaters and gas water heaters For water heaters, maintenance is more difficult, and lightning protection facilities need to be installed
