Abstract

The utility model relates to a heating device of a quick-heat type electric water heater, which can effectively utilize heat efficiency and decrease electric leakage and has the structure that an electric heating wire heater is embedded into a coiled pipe, an electric heating wire sleeved by heat resistant insulating bushes with certain spacings is sealed in a box-shaped double-layer spiral coiled pipe with a minimum space, the box-shaped double-layer spiral coiled pipe is formed by coiling one cupper pipe, the upper layer of the box-shaped double-layer spiral coiled pipe is provided with a water outlet, and the lower layer is provided with a water inlet. The utility model prolongs the time needed by water to absorb heat energy because the box-shaped double-layer spiral coiled pipe is formed by coiling the cupper pipe, thereby enhancing the heat efficiency. In addition, the electric heating wire with the heat resistant insulating bushes is sealed in the box-shaped double-layer spiral coiled pipe, the heat energy is the water which is baked and then flows through the box-shaped double-layer spiral coiled pipe, and the electric heating wire is not directly contacted with water so as to effectively decrease the electric leakage.

Description

The embedded electrothermal wire heating's device of coil pipe

Affiliated technical field

The utility model relates to a kind of electro-heat equipment of quick-heating electric water heater.Especially can efficiently utilize the electro-heat equipment of the thermal efficiency.

Background technology

The electro-heat equipment of present known quick-heating electric water heater is that heating wire is penetrated metal tube, fills the quartz particles insulation in the pipe and the electro-heat equipment of composition.Electro-heat equipment is directly placed water, reach purpose the water heating.Quick-heating electric water heater is the device that can flow out hot water fast, and it is shorter that water absorbs the time of existing electro-heat equipment heat energy, so the thermal efficiency is lower, so must use more powerful electro-heat equipment.Electro-heat equipment directly places water, if the electro-heat equipment electric leakage can directly be conducted by water, causes shock hazard.

Summary of the invention

In order to overcome the electro-heat equipment of existing quick-heating electric water heater, can not efficiently utilize the thermal efficiency, the deficiency of the electric leakage hidden danger that the bigger and electro-heat equipment of power directly places water and brought.The utility model provides a kind of electro-heat equipment of quick-heating electric water heater.The embedded electrothermal wire heating's device of coil pipe, this utility model can not only efficiently utilize the thermal efficiency, and power is less, can also effectively reduce the generation of electric leakage accident.

The technical scheme that its technical problem that solves the utility model adopts is: the double-deck box-like spiral coil that is coiled to form by a copper pipe, one of the upper strata is delivery port, one of lower floor is water inlet, one determining deviation is with the heating wire of high temperature insulation cover, be sealed between the two-layer spiral coil that scribbles heat resistant varnish with minimum space, central authorities of spiral coil lower floor reserve the round mouth place, put into the power supply insulator and introduce power supply, water inlet is connected the water source, after the energising, the heat energy of heating wire, the water that is flow through in the spiral coil absorbs.Because spiral coil is to be coiled to form by a copper pipe, prolong water and absorbed the time of heat energy, so can efficiently utilize the thermal efficiency, also correspondingly reduced the power of the heating element of the embedded heating wire of coil pipe simultaneously.Have the heating wire of high temperature insulation cover, be sealed in the middle of the spiral coil that scribbles heat resistant varnish, the heat energy of heating wire is that the water in the spiral coil is flow through in baking, and direct contact water does not so just greatly reduce the shock hazard that causes because of electric leakage.

The beneficial effects of the utility model are: can efficiently utilize the thermal efficiency, effectively reduce electric leakage hidden danger, technology is simple, and spiral coil can be reused.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified

Fig. 1 is circuit theory diagrams of the present utility model

Fig. 2 is an embodiment vertical profile structural map of the present utility model

Fig. 3 is a plane of the present utility model

Among the figure: water inlet (6) delivery port (1) spiral coil (2) high temperature insulation cover (3) heating wire (4) power supply insulator 5)

The specific embodiment

In the embodiment of Fig. 2, heating wire (3) is that dish is made circular member, and round member central authorities are stayed at two of heating wire (3), so that introduce power supply.Along the line every spacing 30 millimeter at heating wire (3) are with a high temperature insulation cover (2).With heating wire (3) with minimum space be sealed in by a copper pipe dish system form two-layer up and down, there is delivery port (6) on the upper strata, lower floor has in the box-like spiral coil (1) of water inlet (5).Spiral coil scribbles heat resistant varnish in (1), and lacquer can be fixed high temperature insulation cover (2) after doing, and heating wire (3) can not be gone here and there.Also play simultaneously the effect of two minor insulation, central authorities of lower floor reservation round mouth place at spiral coil (1) puts into power supply insulator (4), introduce power supply, water inlet (5) connects the water source, the heat energy of energising back heating wire (3) is absorbed by the water that spiral coil (1) flows through, and has been heated to finish when delivery port (6) flows out again.

Claims (2)

1, the embedded electrothermal wire heating's device of a kind of coil pipe, heating wire is sealed in the box-like spiral coil, central authorities of spiral coil lower floor reserve the round mouth place, put into the power supply insulator, introduce power supply, it is characterized in that: the heating wire that a determining deviation is with the high temperature insulation cover, be sealed in minimum space and be coiled to form by a copper pipe, one on upper strata is a delivery port, and one of lower floor is a water inlet, in the middle of the box-like two-layer spiral coil.
