Description
The utility model belongs to a kind of Electric heating bar.
Electric heating bar is mainly used in the electric heater, usually put the cold water that in the water of the water tank of electric heater, is used to heat this jar, Electric heating bar uses heating wire as heating element, because Electric heating bar is put in the water of conduction, this just require Electric heating bar must sealing and housing must insulate with its interior heating wire.Electric heating bar normally coils heating wire in Stainless Steel Shell, with the fixedly heating wire of magnesium powder that insulate, but facts have proved the insulating material of magnesium powder as the parcel heating wire, expands in heating back easily oxidation, thereby causes electric leakage and puncture insulating barrier, therefore Electric heating bar is short useful life, though also have heating wire is put the Electric heating bar existence that is fixed on metal shell in magnetic tube again, this Electric heating bar power is little, can not change and repair, cost of manufacture is big, and useful life is short.
The purpose of this utility model is a kind of Electric heating bar of design, with the fixedly heating wire of watt frame that insulate, makes Electric heating bar have easy making, and easily replacing and easily repairing inner member are safe and reliable, the advantage of perfect heat-dissipating and long service life.
The utility model is made up of resistance wire and housing, in the housing of Electric heating bar, be provided with insulation watt frame, an insulation watt frame is the cylinder bodily form, an insulation watt frame is provided with perforation, perforation vertically is distributed in the periphery of insulation watt frame, the outer end periphery of boring a hole communicates less than the periphery of the distance of the diameter insulation watt frame corresponding with it, the one end middle part of insulation watt frame is provided with boss, other end middle part is provided with the groove that can block the boss that crouches, fixing hole connects boss and groove, screw rod is located in each insulation watt frame is fixed as one, and heating wire is located in the perforation of each insulation watt frame perforation.The said structure design has realized the purpose of this utility model.
The utility model has the advantages that with the fixedly heating wire of watt frame that insulate, make Electric heating bar have easy making, easily change and repair inner member, safe and reliable, the advantage of perfect heat-dissipating and long service life.The more traditional hot water speed of the electrically heated rod of the same after tested power of the utility model is fast 20 percent, prolongs 2～3 times useful life, and it is short to change and repair the inner member time, and cost of manufacture is low.
Below in conjunction with Figure of description structure of the present utility model is further described.
Fig. 1, be the utility model schematic diagram.
Fig. 2, be insulation of the present utility model watt frame schematic diagram.
As depicted in figs. 1 and 2, the housing 2 of Electric heating bar of the present utility model is identical with the housing of traditional Electric heating bar, it is barrel-shaped also to make cylinder with stainless steel, it is arranged in the water tank of electric heater, be usually located at the bottom of water tank, 1 of the sealing panel of Electric heating bar one end is positioned at outside the water tank, and panel and housing are fixed as one, also available bolt connects, and is used for unloading at any time lower panel and changes inner member outside water tank.
In the housing of Electric heating bar, be provided with insulation watt frame 3, an insulation watt frame is the cylinder bodily form, an insulation watt frame is provided with perforation 5, perforation vertically is distributed in the periphery of insulation watt frame, the outer end periphery of boring a hole communicates less than the periphery of the distance of the diameter insulation watt frame corresponding with it, the one end middle part of insulation watt frame is provided with boss 9, other end middle part is provided with the groove that can block the boss that crouches, fixing hole 10 connects boss and groove, screw rod is located in each insulation watt frame is fixed as one, and heating wire 6 is located in the perforation of each insulation watt frame perforation.Each insulation watt frame headtotail, the boss of front end just in time withstands in the respective slot of another insulation watt frame rear end, the screw rod that runs through in each fixing hole is fixed as one supporting disk around the interior heating wire of perforation on each insulation watt frame, because heating wire is positioned at perforation, the perforation again with the insulation watt frame periphery metric space is arranged, can guarantee that again heating wire does not contact housing so can guarantee the heat radiation of heating wire, thus effectively insulation.Two ends in housing also are provided with insulating trip 4, and in order to the heating wire that expose at the insulation two ends, an insulation watt frame is made with heat proof material, and the perforation on it is 4～9, and the best is 6, can be provided with heating wire length as required.
The two ends of heating wire are enclosed within the insulation magnetic tube 7 and are drawn the Electric heating bar case panel and joined with power supply by lead 8, and the face of opening when needing to change element is pulled the damage element that the insulation watt frame that takes out bunchiness changes on it and got final product.
In a word, the utlity model has easy making, easily change and repair inner element, safe and reliable, heat radiation The advantage of the good and long service life of performance. The utility model can be widely used in the various electric heaters.
