Abstract
The utility model relates to an energy-saving electric heating tube which is applied to electric heating appliances, such as water heaters, electric boilers, electric air curtains, electric radiators, etc. A high-temperature ceramic tube is arranged in a stainless steel protective sleeve, and an insulating layer of heat-conductive powder is arranged between the ceramic tube and the protective sleeve. The interior of the high-temperature ceramic is provided with four long through holes, and a spiral resistance wire passes through the four through holes of the high-temperature ceramic tube in W shape. Inner interstices of the through holes are filled with fillers which can energize for heating, and both ends of the protective sleeve are sealed. The leading end of a conducting wire is in screw thread connection with the stainless steel protective sleeve for the conducting wire, and the led conducting wire is connected with a power supply through passing through the protective sleeve for the conductor wire. The product can increase heat effect, and the outward dissipation of the heat is prevented. The heating time is short, the heating is quick, and constant heating time is long. The led conducting wire is provided with a protecting tube, the depth of the electric heating tube in the water can be regulated according to the requirement of users, and the purposes of safely and insulating property are played.
Description
The utility model relates to a kind of energy saving electric heating pipe that is applied on the electroheat equipments such as water heater, electric boiler, electric wind curtain, electric heater.
The electrothermal tube structure that generally uses in the market is " U " type as resistance wire and is arranged in the metallic sheath; filling insulating heat-conductive powder between resistance wire and stainless steel sleeve; this product by heating time is long; heat radiation is very fast; power consumption is big; the heat efficiency is low, and electrothermal tube lead-out wire unprotect device can't be provided with the heat penetration of electrothermal tube in water by customer requirements.
The purpose of this utility model provides a kind of in the utmost point rapidly heating and can keep the energy saving electric heating pipe of higher temperature under outage condition for a long time in the short time.
For achieving the above object; the technical solution of the utility model is: a kind of energy saving electric heating pipe; comprise the stainless steel protection cover; the conductive powder insulating barrier; spiral resistance wire; in the stainless steel protection cover, be provided with high-temperature ceramic; it between earthenware and the protective sleeve conductive powder insulating barrier; high-temperature ceramic can be several side's bodies or the circle ceramic block is formed; be provided with four long through-holes in each ceramic block; the hole, hole is relative; spiral resistance wire is four through holes that " W " type passes high-temperature ceramic; its through hole internal pore is filled with the filler that can encourage heating; the protective sleeve two ends are airtight, and wherein the wire terminals end is provided with screw thread, and do not lure steel wire-protecting cover to be screw thread to be connected; draw lead and be with porcelain ring insulating barrier, pass the wire-protecting cover.
The utility model spiral resistance wire adopts " W " type to pass through high-temperature ceramic; pass the electrothermal tube protective sleeve four times; the electric induction that produces can excite the filler heating in the earthenware; increase thermal effect; it is short to reach heating time; heat up rapidly; continuous long effect of hot time; this product energising 4 minutes, temperature can reach 1000 ℃, during the room temperature appropriateness; can keep high temperature after the outage 40 minutes; draw lead and be provided with protection tube, can regulate the degree of depth of electrothermal tube in water, play the purpose of safety, insulating properties by customer requirements.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the schematic diagram that " W " type passes electrothermal tube for the utility model spiral resistance wire.
Fig. 3 is a refractory ceramics tube side body drawing in side sectional elevation.Fig. 4 is a high-temperature ceramic circle drawing in side sectional elevation.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further: a kind of energy saving electric heating pipe; comprise stainless steel protection cover 1; conductive powder insulating barrier 2; spiral resistance wire 3; in stainless steel protection cover 1, be provided with high-temperature ceramic 4; be conductive powder insulating barrier 2 between earthenware 4 and the protective sleeve 1; high-temperature ceramic 4 can be several side's bodies or the circle ceramic block is formed; be provided with four long through-holes 5 in each ceramic block; the hole, hole is relative; spiral resistance wire 3 is four through holes 5 that " W " type passes high-temperature ceramic 4; its through hole 5 internal pores are filled with the filler 6 that can encourage heating; protective sleeve 1 two ends are airtight; wherein the wire terminals end is provided with screw thread; be screw thread with stainless steel wire-protecting cover 7 and be connected, draw lead 8 and be with porcelain ring insulating barrier 9, pass wire-protecting cover 7.Energized during use; spiral resistance wire heating in the protective sleeve; and generation electric induction; excite the filler heating in the earthenware; make the filler gluing, play the effect of conduction fast of protective resistance silk and heat simultaneously again, draw lead and be provided with protection tube; can regulate the degree of depth of electrothermal tube in water by customer requirements, play the purpose of safety, insulating properties.
