Abstract
The utility model relates to a heater, specifically say the heater that is used in the thermos, it comprises steel pipe, electric stove silk, iron wire, air vent, base, bottle plug, plastics handle, power cord, and its characteristics are that the outside sintering one deck enamel glaze of steel pipe, its inside packing have porcelain tube, and the steel pipe is bent into the U-shaped after the draw processing, has increased density for heat transfer rate has prolonged the life of heater. The utility model discloses changed the outside direct and water contact of traditional heater, but enamel glaze at first contacts with water, and inner structure is reasonable, is the more ideal heater of being used in on the thermos flask at present.
Description
The utility model is a kind of heater with relating to, belongs to electrical heated appliance, more particularly is the heater that is used in the thermos flask.
Existing heater (being commonly called as immersion heater), internal structure is after with insulating material electric furnace heating wire being wrapped, pack in the copper pipe of certain specification, the major defect of its structure is that inside has two layer of air heat transmission belts, because the heat transfer efficiency of air is low, the internal heat of heater can not be spread out of very soon, thereby inner heat reach 1000C ° more than the degree.Because of electric furnace heating wire is often at high temperature worked, so electric furnace heating wire often is blown, influence the life-span, the heater that installs directly contacts with water,, corrosion oxidized in water because of the normal phase of copper pipe, indivedual copper pipes have sand holes dew to occur oozing through corrosion, make the electric furnace heating wire short circuit.
The purpose of this utility model is to overcome above-mentioned disadvantage, and a kind of reasonable in internal structure is provided, the heater that the outside sintering one deck of heating tube vitreous enamel and water directly contact.
In order to achieve the above object, the utility model is to realize like this, constituted by steel pipe 7, electric furnace heating wire 9, iron wire 6, air vent hole 4, base 3, bottle stopper 5, plastic handles 2, power line 1, be characterized in steel pipe 7 outside sintering one deck vitreous enamels 8, its inner filler 10 of filling, electric furnace heating wire 9 strings have porcelain tube 11.
The utility model is simple in structure, and is easy for installation, heat efficiency height, and long service life is a kind of more satisfactory heater that is used at present on the thermos flask.
Description of drawings:
Fig. 1 is a front view of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the B-B cutaway view of Fig. 1.
The explanation of accompanying drawing drawing:
1 power line; 2 plastic handles; 3 bases; 4 air vent holes; 5 bottle stoppers; 6 iron wires; 7 steel pipes; 8 vitreous enamels; 9 electric furnace heating wires; 10 fillers; 11 porcelain tubes.
In order to understand better and to implement, it is as follows with the accompanying drawing to be that embodiment further specifies below: heater is based on steel pipe 7, externally sintered one deck vitreous enamel 8, interior envelope electric furnace heating wire 9, iron wire 6, electric furnace heating wire 9 spirality are in steel pipe, in order to make between electric furnace heating wire and the electric furnace heating wire, insulation between electric furnace heating wire and the steel pipe, porcelain tube 11 on the string, by the diameter of porcelain tube electric furnace heating wire pitch evenly separated, and guarantee that heating evenly; In order to make electric furnace heating wire motionless at the steel pipe internal fixation, heat transfer efficiency is good, guarantee the insulation, in filler 10.Two terminations of two termination iron wires 6 of electric furnace heating wire, bottle stopper 5 is passed at the two ends of steel pipe, is injection-moulded in base 3, and two terminations in addition of iron wire exceed steel pipe slightly, so that weld mutually with power line 1.Steel pipe exceeds base 2-3mm slightly, opens the air vent hole 4 of a φ 3-5mm on bottle stopper.It is 9mm that steel pipe can adopt diameter, and wall thickness is the steel pipe of 1mm, and handling φ through the place pipe is 7mm, has so just increased the density of steel pipe, and heat transfer efficiency is increased, and has reduced the dew that oozes of steel pipe sand holes.The steel pipe middle part can curve and U type shown in Figure 2, the vitreous enamel of the outside sintering one deck of curved good back steel pipe 0.3-0.5mm, electric furnace heating wire available iron chrome-aluminium wire, diameter is 0.3mm, iron wire φ is 5mm, opens a seam with the electric furnace heating wire joint, electric furnace heating wire is clipped in the inside fixes, iron wire is got about long 150mm, filler can adopt magnesia powder, and the specification of porcelain tube is long 20mm, external diameter 6.5mm, internal diameter 4.5mm, air vent hole is selected diameter 3～5mm for use, and the steel pipe of wall thickness 1mm gets final product, and bottle stopper is general vacuum bottle plug, base can be injection-moulded in the two ends of ambroin with steel pipe, be threaded on the external diameter, plastic handles 2 outsides are six prismatics, and internal diameter is threaded, on stay a hole, can adopt injection molded of insulating material.Power line is passed the last hole of plastic handles, connect an attaching plug, plastic handles is screwed on the base gets final product.The power supply of heater is 220V, and power is 700～800W, as long as heater is positioned in the thermos flask, plugs in during use, and one bottle of cold water is as long as can reach 100C ° of degree in 12-15 minute.
Claims (4)
1, a kind of heater is made up of steel pipe 7, electric furnace heating wire 9, iron wire 6, air vent hole 4, base 3, bottle stopper 5, plastic handles 2, power line 1, it is characterized in that steel pipe 7 outside sintering one deck vitreous enamels 8, its inner filler 10 of filling, and electric furnace heating wire 9 strings have porcelain tube 11.
2, by the described heater of claim 1, it is characterized in that steel pipe 7 curves the U type behind the draw.
