Abstract
The utility model relates to a heat exchanger for an electric water heater, which comprises a casing on which a water inlet tap and a water outlet tap are arranged, wherein, an electric heating apparatus which is connected to power supply by conducting wires is arranged in the casing. The utility model is characterized in that a hot water pipe coil is connected between the water inlet tap and the water outlet tap, and the water pipe is arranged in a circle in the casing; an insulating and sealing apparatus is arranged between the electric heating apparatus and the casing in which oil is filled. The utility model has better insulating performance and can provide security in use and higher heat efficiency; meanwhile, the phenomenon of dry combustion does not exist, and hot water can be continuously supplied for a long time.
Description
The utility model relates to a kind of electric heating shower, specifically a kind of heat-exchange device of electric heating shower.
The water heater of electroheating type is at present employed a kind of convenient and swift, and does not have a kind of electric equipment products commonly used in the family of any pollution.And present electric heating shower both domestic and external is divided into two kinds of forms: a kind of is the heat storage type water heater, and another is a directly-heating type water heater.The principal character of two kinds of water heater structures all is to utilize an electric heater unit directly the water in the housing to be heated.Because this electric heater unit conducts electricity, and the water that it directly heats also conducts electricity, therefore must install various safety devices additional to this kind electric heater, although manufacturer is taking strict security means aspect the manufacturing assembling of electric heater, and installed earth leakage circuit-breaker additional in the automatically controlled part of electric heater, but because the inadequate natural endowment of traditional various electric heater structural designs, and make the error of assembling on the link, still exist the phenomenon of many unsafe factors and electric leakage; Owing to raw-material reason, the water in the water heater housing often is being under the effect of heater under the situation of boiling, the very easily oxidation fouling of the inwall of housing, and the service life of not only having reduced water heater, and seriously influenced the heat exchange efficiency of water heater; If in water heater, do not have in addition to be in the state of dry combustion method under the situation of water, heater can be burnt out, make water heater therefore lose the function of using.
The purpose of this utility model is to provide a kind of heat-exchange device of electric heater, makes it have the good insulation performance, and security in the use and higher heat exchange efficiency are provided, and does not have the phenomenon of dry combustion method simultaneously, serially hot-water supply for a long time.
The purpose of this utility model is achieved in that a kind of heat-exchange device of electric heater, include a housing, housing is provided with a water inlet tap and faucet, be equiped with an electric heater unit in the housing, this electric heater unit is connected in power supply by lead, it is characterized in that being provided with a hot-water coil pipe between described water inlet tap and the faucet, this water pipe is located on enclosure interior; Be provided with insulation seal device between described electric heater unit and the housing; Be filled with oil in the housing.
The purpose of this utility model also can be realized by following measure, described electric heater is made up of support and the electrical heating wire that is fixed on this support, this electrical heating wire is connected in lead, wall of housing is provided with a through hole, prop up and be set up in this through hole, the upper end of support is provided with a bulge loop, and this bulge loop is bolted on the housing; Described insulation seal device is for being located between through hole and the support, the lower surface of support bulge loop and the insulated enclosure pad between the shell wall side, this support is a hollow cylinder, be filled with the insulated enclosure medium in this hollow cylinder, above-mentioned electrical heating wire plug-in mounting is gone in the interior insulated enclosure medium of this hollow cylinder, and is connected in lead.Be located at the water pipe between faucet and the water inlet tap, can be located at enclosure interior in the helical form domain.Be provided with U type insulator seal ring between water inlet tap and faucet and the housing.Loading in the oil of housing is insulating oil.
Effect of the present utility model is significant, it has overcome the method that existing electric heater adopts electric heater directly water to be heated fully, but utilize electric heater that the oil that has insulating properties in the housing is heated, by insulating oil the heat of electric heater is conducted to hot-water coil pipe again, a kind of like this method of indirect has fundamentally solved the electric leakage hidden danger of electric heater.And in the utility model at electric heater, water inlet tap and faucet all and be in fully the state of insulation between the housing of water heater, and hot-water coil pipe do not contact fully with housing, so security performance is fabulous.Because hot-water coil pipe is fully immersed in the insulating oil of high temperature, can the oxidation fouling on tube wall, heat conductivility is fabulous, therefore has higher heat exchange efficiency; Electric heater is to be immersed in the insulating oil in addition, so the phenomenon of dry combustion method can not occur, guarantees the normal use of water heater, and prolongs its service life.
