Abstract
The utility model discloses a heating device for electric water heaters. Four small through holes at least are arranged between a through hole and an outer circle which are arranged on an electric heating core 1, and are distributed along the direction of the through hole. An electric furnace wire 8 is hermetically fixed on the small through holes by filling material 9. One end of the electric heating core 1 is connected with a tail end 3, and the other end of the electric heating core 1 is connected with a heat insulation cushion 4 and a heat end 2. Both ends of the electric furnace wire 8 are connected with a terminal 16 of the heat end 2. The utility model solves the short circuit and the burnout caused by the heating and the deformation of the electric furnace wire, and the service life improves two to three times. As the electric heating core is provided with the through hole, the heat dissipation area is increased, and the heat efficiency improves 20-40%.
Description
The utility model relates to electric heater unit, is specifically related to the heating apparatus of electric water heater that people are used in family, hotel, dining room and enterprises and institutions.
Heating apparatus of electric water heater of the prior art, mainly be to constitute by heating core and electric furnace heating wire, have a plurality of grooves at the heating core outer round surface along centerline direction, electric furnace heating wire places in its groove, and it exists not enough: the one, place electric furnace heating wire in the heating core fluting in the heating use, because of heating produce deformation displacement cause adjacent disc around electric furnace heating wire link to each other, cause electric furnace heating wire to reduce because of contraction in length resistance, electric current strengthens, and electric furnace heating wire is burnt, and reduces useful life; The 2nd, heating core does not have the heat radiation mesopore, and area of dissipation is little and the heat efficiency is low.
The heating apparatus of electric water heater that the purpose of this utility model is to provide a kind of long service life and improves the heat efficiency.
The technical solution of the utility model is achieved in that this heating apparatus of electric water heater mainly is made of heating core and electric furnace heating wire, and improvements are: heating core is provided with the hollow form through hole; On the circular heating core between its through hole and the cylindrical, be provided with 4 small through hole that distribute along the through hole direction at least, electric furnace heating wire is sealingly fastened in the small through hole by inserts; The not termination that is provided with the hollow form through hole equally is connected in heating core one end; The heating core other end is connected with heat insulating mattress and head end head; The electric furnace heating wire two ends link to each other with terminals on the head end head respectively.
When implementing technique scheme, adopting the heat insulating mattress and the head end head that are connected in the heating core other end usually also can be the hollow form through hole.On heating core cylindrical and through-hole surfaces that pottery constitutes, difference sintering one glazed layer.
Electric furnace heating wire of the present utility model is sealed in the small through hole of heating core, and is provided with the inserts sealing and fixing, has prevented electric furnace heating wire heating deformation displacement and causes that the electric furnace heating wire short circuit burns.After tested, improve useful life more than 2 times than original heating apparatus of electric water heater.Heating core is provided with the hollow form through hole, and not only cylindrical can dispel the heat, and its endoporus also can dispel the heat, and has increased area of dissipation, test comparison: improve 20～40% than the original electric heater electric calorifie installation heat efficiency.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Fig. 1 has the syndeton schematic diagram of section for the utility model;
Fig. 2 looks enlarged diagram for the left side of Fig. 1;
Fig. 3 for the A-A of Fig. 1 to analysing and observe enlarged diagram;
Fig. 4 is a kind of embodiment user mode syndeton schematic diagram;
Fig. 5 is another kind of embodiment user mode syndeton schematic diagram.
Embodiment 1, with reference to Fig. 1, shown in Figure 4.Heating core 1 is provided with the hollow form through hole; On the circular heating core 1 between its through hole and the cylindrical, be provided with 14 along the equally distributed small through hole of through hole direction, electric furnace heating wire 8 is filled by modified oxidized magnesium granules inserts 9 and is fixed in 12 small through hole, and 10 sealings (shown in Figure 3) of sealing material are adopted at the small through hole two ends.2 bolts 5 run through respectively in the small through hole, and the not termination 3 that also is the hollow form through hole is connected in heating core 1 one ends, and heat insulating mattress 4 and head end head 2 are connected in heating core 1 other end.Electric furnace heating wire 8 two ends link to each other with terminals 16 on the head end head 2 respectively (shown in Figure 2).Described heating core 1, termination 3, heat insulating mattress 4, head end head 2 do not adopt ceramic sintering respectively.Be to increase radiating effect, on the surface of the cylindrical of heating core 1 and through hole, sintering one glazed layer 6 and 7 respectively except preventing that pottery from easily the moisture absorption, also having played the effect of far-infrared radiation layer, has strengthened the radiating effect of heating core.
During use, referring to Fig. 4.The utility model is connected in water tank 11 inner chambers, and left end cap upper shield 12 is connected the 220V power supply, and electric furnace heating wire 8 makes the cylindrical and the endoporus distribute heat of heating core 1, and the water in the water tank 11 is fully heated, and running water enters from water inlet 14, discharges from delivery port 17 after heating.
Embodiment 2, and is shown in Figure 5.With embodiment 1 different be that referring to Fig. 1, the heat insulating mattress 4 and the head end head 2 that are connected in heating core 1 other end also are the hollow form through holes.
During use, enter the running water heating of water tank 11 inner chambers from water inlet 14 after, discharge from the delivery port 15 that runs through heating core 1 hollow form through hole.
According to different use occasion needs, heating core 1 can be designed to multi-segmental and axially connect, and is concatenated into one by electric furnace heating wire 8, bolt 5; Inserts 9 can also be oxide particles such as silicon dioxide, aluminium oxide; These variations all belong within the protection range of the present utility model.
