Abstract
The utility model discloses an electricity leakage protection and scaling protection electrical heating tube for water heater, which comprises calorigenic heating wire, a protective sleeve of heating wire; an outer casing keeping certain of space from the protective sleeve, the end of outer casing has a flange for fixing; the clearance between the outer casing and the protective sleeve is sealed and filled with heat conduction oil; by adopting the above structure, the temperature of the outer casing can be controlled below 80 degrees to avoid surface scale of the outer casing, meanwhile, the heat dissipation surface can be increased; because the transformer oil between the outer casing and the protective sleeve has insulating function, the electrical leakage of electrical heating tube can also be avoided.
Description
Technical field
The utility model belongs to a kind of water heater, particularly relates to a kind of water heater with anticreep, good antiscale property electric heating tube.
Background technology
General water heater according to the difference of mode of heating, is divided into electric heater, gas water heater, solar water heater usually.
At present, electric heater generally includes the storage tank that the outside is formed with the certain thickness heat-insulation layer, and to the electric heating tube that the storage tank internal water heats, temperature controlled temperature control parts are carried out in heating to the storage tank internal water.Electric heating tube generally is made of heating wire and protective sleeve, by the water heating of protective sleeve with storage tank inside.
But above-mentioned electric heating tube; owing to be that protective sleeve directly contacts with water; protective sleeve surface transient temperature is very high; long-time use can cause the protective sleeve surface scale; cause the protective sleeve radiating efficiency to reduce, simultaneously, long-time use can cause the protective sleeve surface corrosion; produce electric leakage, damage to the user.
Summary of the invention
The utility model provides a kind of water heater with anticreep, good antiscale property electric heating tube for solving the technical problem that exists in the above-mentioned technology.
The utility model is that the technical scheme that the technical problem that exists in the above-mentioned technology of solution is taked is:
A kind of water heater of the present utility model includes the heating wire that produces heat with anticreep, good antiscale property electric heating tube; The protective sleeve of protection heating wire; Protective sleeve also is formed with outward apart from the overcoat of protective sleeve certain space; The overcoat end is formed with the fixing flange of using; Sealing and falling heat-transfer oil between overcoat and the protective sleeve; Be formed with the tripod ceramics bracket between overcoat and the protective sleeve; Outer cover inwall place is provided with the temperature control rod; The place, space that flange is communicated with between overcoat and the protective sleeve is provided with the compensation oil pipe that compensates conduction oil; Be provided with slidably buckling sealing plug in the compensation oil pipe of compensation conduction oil; The compensation oil pipe end is formed with sealing cap; Be provided with the sealed insulation pad between protective sleeve and the flange; Conduction oil adopts transformer oil usually.
Advantage and the good effect that the utlity model has are: a kind of water heater of the present utility model is with anticreep, good antiscale property electric heating tube, owing to adopt said structure, outer sheath temperature can be controlled at and prevent the sleeve surface fouling below 80 ℃, simultaneously, increase area of dissipation.Owing to be formed with the effect that transformer oil plays insulation between overcoat and the protective sleeve, prevent the electric heating tube electric leakage, damage to the user.

The specific embodiment
For further understanding content of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
A kind of water heater of the present utility model includes the heating wire (not shown) that produces heat with anticreep, good antiscale property electric heating tube; The protective sleeve 1 of protection heating wire; Protective sleeve also is formed with the overcoat 2 apart from the protective sleeve certain space outward; Overcoat 2 ends are formed with fixing with flange 3; Sealing and falling heat-transfer oil 4 between overcoat 2 and the protective sleeve 1; Be formed with tripod ceramics bracket 5 between overcoat 2 and the protective sleeve 1; Outer cover inwall place is provided with temperature control rod 6; The place, space that flange 3 is communicated with between overcoat 2 and the protective sleeve 1 is provided with the compensation oil pipe 7 that compensates conduction oil 4; Be provided with slidably buckling sealing plug 8 in the compensation oil pipe 7 of compensation conduction oil 4; The compensation oil pipe end is formed with sealing cap 11; Be provided with sealed insulation pad 9 between protective sleeve 1 and the flange 3; Conduction oil 4 adopts transformer oil usually.
Connect power supply when heating wire, produce heat, conduct heat in the conduction oil 4 by protective sleeve 1, with the heating of the water in the water heater, because water does not directly contact with protective sleeve 1, therefore, protective sleeve 1 can not corroded by overcoat 2 in conduction oil 4 heating backs.Owing in conduction oil 4, be provided with the temperature control rod, conduction oil 4 temperature are controlled at below 80 ℃, overcoat 2 contacts also non flouling behaviour with water.Simultaneously, overcoat periphery area is big, is beneficial to heat radiation.Because expanding with heat and contract with cold, compensation oil pipe 7, conduction oil 4 can not cause overcoat 2 distortion.Be provided with sealed insulation pad 9 between protective sleeve 1 and the flange 3, electric heating tube can not leaked electricity.Protective sleeve 1, overcoat 2 and flange 3 adopt copper material corrosion-resistant, that heat conduction is fast or stainless steel material to constitute usually.In 7 li in compensation oil pipe, according to the thermal coefficient of expansion of conduction oil 4, when buckling sealing plug 8 slides into certain position, set up a temperature switch, control the temperature of conduction oil 4 simultaneously.
The utility model only exemplifies an embodiment, only be provided with the electric heating tube of in-line heater block in the overcoat 2, certainly, electric heating tube also can be designed to form in the overcoat 2 many group heater blocks or U font heater block as required, and be transmitted on the overcoat 2 heating of the water in the water heater by conduction oil 4 this media, the shape of overcoat 2 and flange 3 also changes.
