Description
Technical field
The utility model relates to a kind of electric heater.Relate in particular to a kind of electromagnetic water heater.
Technical background
Electric heater in the known technology is electric heating element to be placed on after by insulation processing carry out preheating in the water tank, pass through aqueduct shower nozzle then or pass through a series of water temperature controling circuit, incrustation scale processing unit, hydraulic pressure circuit breaker, or the intelligent control of computer controller realizes the heating to water.The electric heating element that they adopt all is that the power conversion with resistance heating directly contacts with water tank water.Its weak point is the power consumption height, and the heat efficiency is low.Water tank takes up room greatly, the preheating stand-by period is long, the water tank moisture storage capacity is limited, can not guarantee enough use hot water flows, therefore regularly heating controller or two-way heating anode stub layering heating technique heat the supply that guarantees hot water in advance to the water that it is stored in the inner water tank, the pre-warmed time needs of the electric heater of common 1500W 1～2 hour at times to have to adopt Computerized intelligent.At secure context,, must adopt proof and electric leakage-proof safety device and electricity-preventing wall device to solve the safety issue of power utilization environment for stopping forward, converse electrical leakage.
In nearly thousand the electric heater patents of invention and utility model patent that openly relates at Chinese patent, almost having accounted for 99% electric heater all is the version of forming with water tank and resistance electric heating element.The electromagnetic water heater more approaching with the utility model, comprise that No. 90224501.5 disclosed a kind of safe electric water heaters of Chinese patent, No. 98216667.2 disclosed magnetic induction type electric heaters of Chinese patent, No. 01206416.5 disclosed quick continous way electric heater of Chinese patent and No. 0117368.5 disclosed induction-type instantaneous electric water heater of Chinese patent have adopted iron core, primary coil and secondary coil, have almost utilized the short circuit heating system of secondary coil to realize the water that flows into its pipeline is heated simultaneously.Wherein the structure of No. 98216667.2 magnetic induction type electric heater Chinese patents is the cold water that flows into becket with the short circuit current heating of one group of entrance point of secondary coil and port of export short circuit weld metal ring successively; 01206416.5 linking to each other with some series connection heating tubes with the short circuit secondary coil in parallel of closed loop, number disclosed quick continous way electric heater heats running water by in its pipe; 0117368.5 number disclosed induction-type instantaneous electric water heater is made heater element with unshakable in one's determination and electromagnetism winding, it utilizes secondary pipeline heating realization that induction produces in the iron core eddy current and multiturn metal tube induction winding head and the tail two terminal shortcircuits the connect heating to water.This class electric heater all is to rely on the secondary short circuit heating of closed loop as load in sum, the potential difference that is reflected at load is almost nil, in theory still, in the utilization of reality, all can not realize the conversion of energy, because there is not the load of the voltage power that is equal to nothing to produce.Actual result can be described as infeasible, or even impracticable.A mode that has also adopted the rectification heating is wherein arranged, rely on the DC heating load, such heating can be described as the heat energy that can not satisfy water heater.Wherein rely on eddy current unshakable in one's determination heating and the secondary heating of short circuit, short circuit secondary actual be not produce heat energy, and the heat energy of eddy current generation also is not enough.The heating element that they structurally need is also many, and structure is more complicated also.Heating element is many, and the electric current shunting is also many, and the hot merit effect is also low.Wherein adopt electric current that heating element in parallel obtains can with heating element increase and declines that is directly proportional, the speed of electric heating is slack-off thereupon, and the cost height, power loss is big, use power height.
Summary of the invention
Big in order to overcome existing water tank electric heater volume, warm-up time is long, can not supply with the deficiency of hot water immediately and overcome to rely on secondary short circuit heating magnetic induction electric heater heating link many, complex structure, the cost height, power consumption is big, defective, it is a kind of simple in structure that the utility model provides, and heating load is direct, and shunt current is few, low-voltage and high-current, safe, power consumption is low, the no water tank electric heater that the heat efficiency is high.
The purpose of this utility model is to realize like this, a kind of no water tank electric heater, the unshakable in one's determination elementary line bag and the secondary spool that comprise an electric connection of power supply, it is characterized in that described iron core is closely around the ring-shaped core that forms by metallic conductor sheet band, but center on the ring-shaped core helix bag of with good grounds heating power size and tap on it, the ring-shaped core centre bore that the metallic conductor hollow pipe that has at least a circle to constitute secondary spool passes described ring-shaped core helix bag directly constitutes heating load, and the water inlet end of this heating load is connected water inlet pipe and outlet pipe respectively with the water side.
The utility model has following useful good effect than prior art.
The utility model is closely tight than the rectangular core that is laminated around the ring-shaped core that forms, and the gap is little, the magnetic flux density height, and eddy current loss is little.Magnetic field line as the ring-shaped core helix packet generation of elementary transformation is concentrated, and magnetic flux density is big, and the load current that obtains by Ampere circuit law is big.The metallic conductor hollow pipe that constitutes secondary spool heating load has made full use of the big electric current heat energy that metallic conductor electric current " kelvin effect " produces and has been collected in heating load, the power height, and power loss is little, power consumption is low, and heating is rapid, heat efficiency height, water temperature is permanent steady, does not have sometimes hot and sometimes cold phenomenon.Operating voltage only has several volts, and environment for use is safe, can not consider that almost proof and electric leakage-proof safety device and electricity-preventing wall device solve the safety issue of power utilization environment.Directly constitute heating load as secondary metallic conductor hollow pipe, overall structure is simple, convenient for installation and maintenance, it is big and wait as long for the problem of heating fundamentally to have solved the existing water tank type electric heater volume that takes up space, overcome and used secondary short circuited load heating electric heater heating link many, complex structure, cost height, power loss is big, uses the high deficiency of power.Wherein cut magnetic field that its spool self the produces formation magnetized drinking water that is magnetized, thereby it is little to produce the probability of incrustation scale by the flow of hot water of secondary spool.
In order to further specify rather than limit above-mentioned way of realization of the present utility model, provide most preferred embodiment below in conjunction with accompanying drawing, thereby make details of the present utility model and advantage become more obvious.
