Application number is 01207751, and the applying date is March 23 calendar year 2001, and denomination of invention is the patent of far infrared tubular type electric heater; comprise water storage tank, end cap, far infrared induction tube; electrothermal tube, instrument, safety guard etc.; it is characterized in that: water storage tank is divided into outer water storage room, interior water storage room, and the two is provided with one heart; outer water storage room two ends are threaded with end cap, and the middle part in its outside is provided with instrument, and the side is provided with electric source connecting box; the bottom side of outer water storage room is provided with blowoff valve, and outer water storage room communicates with water inlet pipe.By said structure as can be known, heat exchange area is big inadequately, and heat exchanger effectiveness is undesirable; Because heat-insulation layer is not set, can not reduce the loss of heat energy to greatest extent again; Because the restriction of structure can not a plurality ofly be used in combination.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of safe, efficient, energy-conservation, ultra-thin and can many far infrared fast electric heating water-heating devices that are used in combination in order to solve above-mentioned deficiency.
The utility model is realized above-mentioned purpose by following technical proposals:
The utility model is to comprise power unit, heat-insulation layer, and it also comprises hot-water line and the far infrared electro-thermal tube of bringing delivery port into, and described hot-water line is a helical form, described far infrared electro-thermal tube be arranged in the helical form hot-water line inner chamber and and inner chamber between have the gap.
Described far infrared electro-thermal tube is concentric with hot-water line, and far infrared electro-thermal tube is quartzy far infrared electro-thermal tube; The hot-water line surface is sprayed with the far infrared coating; The intake-outlet place of described hot-water line is furnished with connecting bolt and attaching nut; quartzy far infrared electro-thermal tube both ends have been provided with the flexible high temperature resistant circle of cushioning effect respectively; the hot-water line arranged outside has the overtemperature prote device; the heat-insulation layer outside and inside thereof are provided with locking device, and locking device comprises locating flange, end cap, screw rod, nuts and washers.
Advantage of the present utility model is: rationally novel in design, technology is simple, makes easily, is fit to produce in batches; Because intake-outlet is horizontally disposed with and can connects, therefore can be as required with they many be used in combination water-heating device such as water heater; Because the far infrared electro-thermal tube temperature raises fast, and high insulating effect, therefore not only energy-saving efficiency but also high; Owing to adopt contactless heating means, be not easy fouling, more safe and reliable; Since simple and reasonable, ultra-thin structure can be made, convenient and practical;
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments
Fig. 1 is the structural representation of the utility model embodiment;
Structural representation when Fig. 2 is used in combination for many of the utility model.
Specific embodiment
As Fig. 1, the utility model comprises that power unit, heat-insulation layer 12, surface are sprayed with the spiral helicine hot-water line 11 and the quartzy far infrared electro-thermal tube 2 of nano-far-infrared coating 15.Electrothermal tube 2 is arranged in the inner chamber of hot-water line 11 and has 3 to 5 mm clearance with hot-water line 11 inner chambers, and hot-water line 11 is concentric with electrothermal tube 2.Hot-water line 11 is a copper tube, also can be aluminum pipe; Heat-insulation layer 12 is positioned at hot-water line 11 outsides, and hot-water line 11 diameters are 6 to 10 millimeters.Electrothermal tube 2 two ends have been provided with the flexible high temperature resistant circle 4 and the spacing axle sleeve 3 of cushioning effect, and hot-water line 11 arranged outside have overtemperature prote device 14.Heat-insulation layer 12 outsides and inside are provided with the fixing and locking device, comprise locating flange 9, end cap 8, screw rod 5, nut 6 and packing ring 7, end cap 8 is positioned at heat-insulation layer 12 two ends, locating flange 9 is positioned at the hot-water line two ends, screw rod 5 is through between locating flange 9 and the end cap 8, and nut 6 is spun on screw rod 5 and packing ring 7 and nut 6 supporting uses.Heat-insulation layer 12 outsides are shells 10; The intake-outlet place of hot-water line 11 is furnished with connecting bolt 1 and nut 13, and water inlet becomes 180 ° of levels with delivery port, so the utility model can many be used in combination, thereby satisfies different users's needs.As Fig. 2, be the structural representation of the water heater that is used in combination of three the utility model.Certainly, the use that also can combine more than two or three.
Operation principle of the present utility model is: connect power supply, quartzy far infrared electro-thermal tube 2 is only with just reaching 600 ℃ to 700 ℃ of design temperatures a second, cold water enters spiral hot-water line 11 simultaneously, carries out heat exchange with quartzy far infrared electro-thermal tube 2, and exchange process is that heat radiation is main comprehensive exchange; Because the effect of heat-insulation layer 12, heat-energy losses is very little; The specific heat C of copper is 0.057, spiral hot-water line 11 weight 0.24Kg, and the thermal energy consumption of hot-water line 11 is 1 kilocalorie, about 1/859 degree electricity can be ignored; Spiral hot-water line 11 about 2 meters long, about 32 circles of helically coiling, heat exchange area is enough big; Spray nano-far-infrared coating 15 has strengthened 2.5 μ to 15 μ absorptivities, and above condition makes its thermal efficiency more than 98%.
Adopting flexible high temperature resistant circle 4 is in order to prevent vibrations or to fall and cause damage, can making quartzy far infrared electro-thermal tube obtain buffering when shaking or falling.The effect of overtemperature prote device 14 is: when having air or lack of water to cause equilibrium temperature to raise in the pipe with spiral pipe 11,14 actions of overtemperature prote device are cut off the electricity supply.Because quartzy far infrared electro-thermal tube 2 does not directly contact with water with hot-water line 11, is electricity separation truly.As from the foregoing, the utility model temperature raises fast, and is energy-conservation, the efficient height; Be not easy fouling, more safe and reliable; Simple and reasonable, can make ultra-thin structure.
