Description
Affiliated technical field
Novel hot water liner of the present invention and production method thereof are to belong to add the environment-friendly type novel hot water liner pollution-free, energy-efficient, rational in infrastructure, that scaling, acid-alkali-corrosive-resisting, safe and reliable, long service life, manufacturing cost are not moderate of hot water and the method for production thereof in the household electrical appliances series such as cold, hot two-purpose water dispenser.
Background technology
Since water dispenser came out, it was that electric pyrotoxin, magnesia powder are that insulator, stainless steel are the electric heating tube that containment vessel is made that the thermal source of the most crucial parts hot water liner of water dispenser adopts with heating wire always.The power density of this electric heating tube is usually up to 30-80 watt/square centimeter, and energising is done work under high like this power density, and electric heating tube itself produces a series of performance deficiencies that are difficult to overcome.As: power consumption is high, the life-span lacks (working life only 2000-5000 hour), the heat that electrothermal tube surface knot porcelain incrustation scale, porcelain incrustation scale obstruction Electrothermic wire send when adding hot water is dispersed into rapidly in the heated water, make heating wire operating temperature excess load, cause fracture of heating wire overtemperature or the explosion of electrothermal tube overtemperature, cause the electric leakage accident simultaneously and take place.
According to an international practice, to the apparatus parts that are used for direct and Food Contact, the very strictness of content restriction of container material Cd cadmium/Pb lead/Hg mercury/heavy metals such as Cr6+ Cr VI.The requirement of the heater surfacing that particularly contacts with water under the condition of high temperature is more harsh, and the U.S. and European Union even do not allow to contain above heavy metal.But the at present domestic content that is used for the stainless steel protection layer material heavy metal chromium of the metallic heating body on the low price water dispenser hot water liner surpasses international standard.People's long-term drinking will have a strong impact on healthy with the water of the heater heating of defective sanitary standard.This is electricity heating industry and the water dispenser industry unsolved always technical barrier that continues into the present.
Summary of the invention
In view of above-mentioned problems of the prior art, the invention provides a kind of energy-efficient, simple in structure, cost is moderate, safe and reliable, life-span length, sanitation and hygiene, acidproof, alkaline-resisting, solid-state dirty body is not tied on the heater surface when particularly adding hot water, does not discharge any novel hot water liner and production method thereof to person harmful substance to heated water yet.Thereby for cold/hot shot water machine etc. paddle the electric heating household electrical appliances and need thermal source other use hot water liner industries to increase a kind of electrical heating hot water liner device of brand new.
The technical solution adopted for the present invention to solve the technical problems is; On the inwall of quartzy tubular body (2), establish Electric radiant Heating Film (3), two silver conductive electrodes of ring-type (4) are established at the two ends of Electric radiant Heating Film (3), a butterfly of squeezing a bloated part (9) and an activity by a butterfly fixing with squeezing bloated screw rod (22) that goes up installation at the crowded screw rod (22) that expands respectively is installed on two electrodes then squeezes bloated part (8), squeeze the part (9 that expands two butterflies, 8) the elastic electrode jam-packed spare of placing in the middle of (7), go up the annular thermal insulation barriers (6) that cover is put at elastic electrode jam-packed spare (7), upward overlap the electrode of putting at annular thermal insulation barriers (6) and draw part (5), the butterfly that is used for the jam-packed activity is squeezed the crowded expansion nut (10) of the part (8) that expands, connect the electrode fixing device that electrode is drawn part (5) and temperature controller (18) and led to electrode wires (15) composition of metal flange line outlet (23) with high temperature resistant wire, and the quartz ampoule electric heating body assembly that is assembled into; The total bunchiness of quartz ampoule electric heating body is provided with to the sidepiece lower end on the metal can (1) of circular hole of installation quartz ampoule electric heating body assembly of two symmetries, heater seal (11) is installed between quartz ampoule electric heating body assembly and metal can (1), heater seal (11) is fixing with metal flange (12), the line outlet (23) of metal flange (12) is with moisture seal spare (13) and fixedly tighten sealing nut (14) sealing of moisture seal spare (13), connect electrode with high temperature resistant wire and draw part (5) and the temperature controller (18) of anti-overtemperature and the electrode wires (15) that is connected with power supply, reach purpose with water in the quartz ampoule electric heating body assembly heating of metal tank body.
Production method of the present invention is, establishes Electric radiant Heating Film (3) on the tubular body inwall of quartzy tubular body (2), establishes the silver conductive electrode of the ring-type that is no less than two (4) on the two ends of Electric radiant Heating Film (3); Install additional under the room temperature environment then with the electrode of conductive electrode (4) equal number and draw assembly.It is by squeezing the crowded part (9) that expands of the butterfly fixing with squeezing the screw rod (22) that expands that the screw rod (22) that expands is upward installed that electrode is drawn assembly, squeeze the part (8) that expands with a unfixed butterfly, with the part (8 that squeeze to expand two butterflies, 9) place elastic electrode jam-packed spare (7) in the middle of, go up cover at elastic electrode jam-packed spare (7) and put annular thermal insulation barriers (6), be mounted on annular thermal insulation barriers (6) top electrode and draw part (5), with squeeze the part (8) that expands with the butterfly of squeezing expansion nut (10) jam-packed activity, and is connected the method that electrode draws part (5) and temperature controller (18) and be extended for electrode wires (15) with high temperature resistant wire and makes; Ready-made electrode is drawn assembly be placed on the position of conductive electrode (4) also with the fastening quartz ampoule electric heating body assembly that is assembled into of specific purpose tool; The total bunchiness of quartz ampoule electric heating body to the circular hole of the installation quartz ampoule electric heating body assembly of two symmetries that are located at metal can (1) sidepiece lower end, a heater seal (11) is respectively overlapped at the two ends of quartz ampoule electric heating body assembly, use metal flange (12) to be mounted on the heater seal (11) again, the fixedly circular hole (24) of metal flange (12) and flange pull bar (17) coordination; With pull-rod nut (16) fastening metal flange (12), the slit between sealing metal tank body (1) and the quartz ampoule electric heating body assembly prevents that the water in the metal can (1) from flowing out outside tank body; Electrode wires (15) is gone here and there moisture seal spare (13) and moisture seal spare (13) is placed in the tubulose line outlet (23), use get lines crossed hole and steam vent on fixing also pressurization tubulose line outlet (23) of sealing nut (14) and the moisture seal spare (13) again; Electrode wires (15) gives over to power supply and is connected.
The present invention has following distinguishing feature:
