Description
Technical field
The present invention relates to a kind of water heater, particularly relate to a kind of energy-saving water heater.
Background technology
The water tank of existing water heater is square, the casing of the shapes such as circle, simultaneously, located therein be all common metal heating rod and this heating rod is also all used to directly insert in water, this makes it can be regarded as point type heating from inside to outside to the mode of heating that water provides, power consumption is large, heating is slow, waste energy, simultaneously, the water tank of existing water heater is subject to the impact of delivery port Position Design, usually the state of trunkful water-filling cannot be reached, so, time one is of a specified duration, the part that water tank does not contact with water for a long time will corrode because being oxidized, cause corrupted, use inconvenience, life-span is short.
Summary of the invention
In view of this, technical problem to be solved by this invention is: provide the energy-saving water heater that a kind of energy consumption is little, heating is fast, the life-span is long.
In order to achieve the above object, the present invention adopts following technical scheme to realize:
A kind of energy-saving water heater, comprise water heater body, described water heater body has tubular type water tank and is electrically connected the electric heating element of external power source, described electric heating element is located in described tubular type water tank, described tubular type water tank has water inlet and delivery port, wherein, the shape of described tubular type water tank is U-tube, described water inlet is positioned at one end of described U-tube, described delivery port is positioned at the other end of described U-tube, described electric heating element is coil the carbon fiber pipe be connected on described U-tube inwall in the shape of a spiral, and the outer wall of described carbon fiber pipe is coated with thermal insulation layer.
As preferably, described water heater body also has the control circuit board be electrically connected between described electric heating element and external power source, described water inlet is provided with water flow sensing unit, be provided with cooling-water temperature sensor in described tubular type water tank, described water flow sensing unit, cooling-water temperature sensor are electrically connected between described control circuit board and external power source.
As preferably, described water inlet is connected with water inlet pipe, described delivery port is connected with outlet pipe, described water flow sensing unit is located in described water inlet pipe.
As preferably, described tubular type water tank is the stainless steel tube that inwall is covered with insulated thermal insulating layer.
As preferably, described thermal insulation layer is Teflon, and described insulated thermal insulating layer is ceramic fibre.
As preferably, between described carbon fiber pipe and described thermal insulation layer, be also connected with nickel-chrome alloy layer.
As preferably, the thickness of described nickel-chrome alloy layer is 0.6mm.
As shown from the above technical solution, the invention has the beneficial effects as follows:
Compared to existing technology, energy consumption of the present invention is little, heating is fast, economize energy, easy to use, the life-span is long.Specifically, coil the carbon fiber pipe be connected on U-tube inwall in the shape of a spiral and obviously can promote the efficiency of heating surface, this is on the one hand because carbon fiber pipe has the characteristic that heating is fast, thermal conversion efficiency is high, simultaneously also because the helical coil design within it on wall of the U-shaped structure of tubular type water tank and carbon fiber pipe.With regard to the former, the carbon fiber pipe of 500 watts of power can realize the heating effect being equivalent to existing 2000 watts of power common heating pipes, can effectively energy-conservation 40% to 60%.With regard to the latter, the flow direction of water that the carbon fiber pipe of helical coil design can hold along U-tube institute carries out the continuous heating of whole process, full enclosed to it, this has become face formula heating from inside to outside with regard to making it to the mode of heating that water provides, revolutionize the defect of original point type heating, energy consumption is little, heating also more saves the energy soon.Moreover, the structural advantage of U-tube is also: during use, and hot water continuously outflows, cold water constantly flows into, and the water in tubular type water tank can keep full pipe condition all the time, water-filling thoroughly can be avoided to be discontented with and cause pipe type water upper box part to be oxidized, the problem of rapid wear of a specified duration, easy to use, the life-span is long.
In addition, owing to being provided with control circuit board, water flow sensing unit and cooling-water temperature sensor, it is then made also to have the function of intelligent temperature control.Water flow sensing unit can by the signal transmission having non-water flow to pass through to control circuit board and control under the control of circuit board electric heating element heating switch, be specially water by time heating, do not have water by time do not heat.In like manner, cooling-water temperature sensor is that water temperature signal is passed to control circuit board, water temperature reaches and heats lower than during a certain value, do not heat higher than during a certain value, the position as cooling-water temperature sensor arranges and the setting of sample magnitude is as the criterion to make the water temperature of outflow tubular type water tank can remain between 40 degree to 100 degree, can be arranged in case everywhere, restriction is not added at this, when temperature being located at 100 degree, water outlet also can be drunk for daily, very convenient.
