Abstract
The utility model discloses an electric water heater belonging to a heating device for domestic water. The electric water heater uses electricity as energy resource and directly uses water as a heating element to be automatically heated. The electric water heater is structurally provided with an electric heater core which is composed of two sets of metal electrode slices. The two sets of metal electrode slices are staggered and laminated. The two sets of metal electrode slices are not mutually contacted. The two sets of metal electrode slices are fixed by an insulating frame. In order to solve the problem that the water which enters or leaves the electric water heater is possibly provided with electricity, the set of metal electrode slices which comprising the outermost layer of the electric heater core needs to be connected with the zero line of a power. Therefore, the water which flows into and flows out the electric water heater is provided with zero potential. The utility model has the advantages of high thermal efficiency, low cost and wide use. The electric water heater can be used as a shower.
Description
The invention belongs to the domestic water heater.
At present, multiple hot-water heater is arranged, but come branch to mainly contain two kinds by the mode of conducting heat, a kind of is immersion, and a kind of is external-heat.Dual mode all with heating wire as heater, heating wire converts electric energy to heat energy, thermal energy transfer is fed water again, this hot-water heater has the loss of part heat in heat transfer process.
Electric heater provided by the invention, be a kind of be the energy with the electricity, be the self-heating device of heater with water, and guarantee flow into and the water that flows out electric heater is zero potential from structure.
The present invention includes a metal shell body, its upper and lower side is lined with a rigid interior cover of insulation of bringing apopore into respectively by a water inlet and a delivery port in the metal shell body, and cover is made up of body and end cap in it.The feature of said electric heater is in the cover electric heater core to be arranged in insulation is rigid, the electric heater core is made up of two groups of metal pole pieces, two groups of metal pole piece intersectings, do not contact mutually, by bolt, insulating sleeve and insulation locating shim it is fixed on the end cap, the metal pole piece has the hole, and most of water is flow through in the hole of metal pole piece, and total sheet number of two groups of metal pole pieces is an odd number.Make electric heater core outermost layer up and down two metal pole pieces be same group, include the zero line that the requirement of the outermost one group of metal pole piece of electric heater core connects power supply, so just guaranteed that from structure the water inlet of electric heater and the water of delivery port are zero potential.Because two groups of metal pole pieces butt joint phase line of power and zero line have certain requirement, so a live wire indicator is arranged on the plug of electric heater, said live wire indicator is made up of neon bulb and resistance.Be connected to desired ground wire of plug and phase line two ends, lamp is bright when plug meets instructions for use with cooperating of socket, otherwise lamp does not work.
In order further to guarantee a detailed catalogue wire netting is arranged personal safety in the metal shell body delivery port, seal delivery port, make the water of delivery port outwards to flow out by the mesh of detailed catalogue wire netting.The detailed catalogue wire netting directly contacts with the metal shell body; and shell body is the requirement reliable ground; promptly require to use the single-phase three-wire plug of band earth connection; the water inlet of the metal shell body of electric heater is to be connected with running water pipe simultaneously, has also utilized this natural grounding substance of metallic conduit to carry out ground protection except the protection of plug ground connection like this.Under the reliable situation of ground protection; when causing phase line and zero line reversal connection owing to improper use or other reason; the major loop of electric current is still by the metal pole piece; has only the small part electric current by detailed catalogue wire netting ground connection; the electrified voltage of the water that flows out from delivery port is still safe and reliable less than 0.5 volt to the person.
Low power electric heater has a wireway in the metal shell body, a delivery port end face that is located on or near the metal shell body of pipe, and the other end is positioned at the top of electric heater core, and wireway makes electric heater core top and the bottom air pressure balance.
Distance dependent between the watt level of electric heater and the metal pole piece gross area and the two groups of metal pole pieces under certain condition of water quality, increases the gross area of metal pole piece and reduces by two groups of distances between the metal pole piece power is increased.
Electric heater is compared with existing hot-water heater, has advantage simple in structure, that volume is little, the thermal efficiency is high, firing rate is fast, and after measured, its electric conversion efficiency reaches more than 91.15%.Generally can obtain 100 ℃ boiling water in second at 4-6, safe and reliable, electrified voltage is less than 0.5 volt in the water.
Being of wide application of electric heater by the control power and the water yield, can be produced multi-purpose electric heater, for example, be used for the shower of toilet, be used for the boiler of diet, the steam generator that is used for steam bath also can be made evaporation-type seawater desalination device peculiar to vessel etc.
Accompanying drawing is above-mentioned electric heater schematic diagram.Electric heater includes a metal shell body (1), its upper and lower side has threaded mouthful intake-outlet respectively, water inlet can be connected with running water pipe, delivery port can be connected with the parts that are applicable to various occasions (as shower head), in the metal shell body, be lined with an insulation of bringing apopore into rigid in cover, cover is made up of body (3) and end cap (2) in it, a wireway (6) is arranged in the metal shell body, in metal shell body delivery port, there is a detailed catalogue wire netting (7) to seal delivery port, in rigid, in the cover electric heater core (4) is arranged, by bolt (8), insulating sleeve (9) and insulation locating shim (5) are fixed on the electric heater core on the end cap (2), and the power line that connects the metal pole piece is drawn through outlet plug (10), and (11) are ground joint, during use, attaching plug correctly uses on request.
Claims (5)
1, a kind of electric heater, comprise metal shell body [1], its upper and lower side has a water inlet and a delivery port respectively, be lined with rigid interior [2], [3] overlapped of insulation of bringing apopore in the metal shell body, the feature of said electric heater be in insulation is rigid, overlapping by an electric heater core [4] of forming by two groups of metal pole pieces, including the outermost one group of metal pole piece of electric heater core is the zero line that connects power supply.
2, according to the said electric heater of claim 1., it is characterized in that said metal pole piece has the hole, total sheet number of two groups of metal pole pieces is an odd number, two groups of metal pole piece intersectings do not contact mutually, are fixed by insulating support.
