Abstract

The utility model discloses a structure for arranging and connecting electrical heating tubes, which is mainly composed of the electrical heating tubes and a metal row. The utility model adopts the methods that electrical heating tubes are in equidistant arrangement in groups, and the wire connection mode is triangular connection. With the structure, the utility model can make the electrical heating tubes connected more conveniently, prevent water leakage, and reduce the volume of an electric heating water-heating machine. In addition, the electric heating water-heating machine with a high power and gradual-heating design is manufactured.

Description

A kind of electrothermal tube is arranged and wiring construction

The utility model relates to a kind of arrangement and wiring construction of electrothermal tube, belongs to electric heating hot water facility class.

The electrothermal tube of existing various electric heating hot water machines is arranged general not grouping, common series or parallel connection method are adopted in wiring, the material of wiring is to adopt cable, the shortcoming of this structure and wiring is the comparison confusion, the phenomenon that easily is short-circuited, and can not realize that classification is progressively heated and the design and the manufacturing of high-power hot water machine.

The purpose of this utility model be a kind of easy-to-connect of design, reliable, be difficult for short circuit, prevent seepage, handling ease, and can realize that classification is progressively heated, the electrothermal heater's of high-power, small size electrothermal tube is arranged and wiring construction.

The purpose of this utility model is achieved in that electrothermal tube 2 is placed in the electric hot water machine body of heater 1, and simultaneously electrothermal tube 2 is fixed on the mounting panel 4 of electric hot water machine one side, and a plurality of electrothermal tubes are divided into several groups, is made up of three electrothermal tubes for every group.For easy to use in the practical application, electrothermal tube 2 is made generally in " U " shape, certainly, also can make " Ω " shape or other shape according to the difference requirement of body of heater.The delta connection in the electrotechnics is adopted in wiring between every group three the electrothermal tube, every electrothermal tube is with other two electrothermal tubes head and the tail are relative on the same group, adopt metal row 6 as the wiring material therebetween, every group electrothermal tube and copper bar constitute an equilateral spill hexagon jointly.

Because the utility model has adopted the delta connection mode, can use the 380V commercial power to power easily, and mounting panel 4 processing of electrothermal tube are than being easier to the debugging convenience of the installation of electrothermal tube, wiring and hot water machine, reliable.Adopt metal row 6 as connecting line between the electrothermal tube, easy to connect reliable, overcome the bad or shortcoming such as come off easily of use common cable wiring contact, also avoid the short circuit phenomenon that causes owing to wiring is improper.Metal row 6 can adopt copper bar or aluminium row, and is preferred material with the copper bar.Has good prospect in actual use.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 2 is the A-A cutaway view;

Fig. 3 is that electric heating hot water machine electrothermal tube is arranged and the wiring construction schematic diagram;

Fig. 4 is the electrothermal tube structure schematic diagram;

Fig. 5 is the copper bar structural representation;

All there is stator 8 two terminations of every electrothermal tube, with holding screw 5 lockings After electrothermal tube can be fixed on the installing plate 4, on the termination of electrothermal tube outer terminal is arranged 3, the fixing hole 7 of arranging two ends with metal is used and metal can be arranged by the wiring requirement Be fixed on the termination of electrothermal tube. In actual applications, the installation of electrothermal tube trend with The direction of current is generally consistent, can slow down like this electrothermal tube owing to water impact produces Vibrations, thereby greatly reduced the drainage of breaking of electrothermal tube. New in this practicality In the type, because every group of electrothermal tube is relatively independent, thus can jointly work, also can be separately Work independently, in actual applications, every group of electrothermal tube all has controller control, works as usefulness When family hot water requirement reduces, can be according to the size of actual amount, electricity that need not be whole Heat pipe but add the water yield in the electric heating hot water machine container with several groups of electrothermal tubes, like this Power consumption is reduced, and saves the energy, and the utility model can also be realized classification progressively Heating makes the distribution of the energy in the whole heating process more reasonable.

Embodiment: according to the above, electrothermal tube 2 adopts " U " pipe, every power is 6KW, and copper bar is adopted in the wiring between the electrothermal tube, and it is 10 groups that electrothermal tube is divided into, every group be shaped as equilateral matrix hexagon, length of side 8cm, electrothermal tube are fixed on the mounting panel 4, and mounting panel is made with boiler steel, electrothermal tube adopts the power supply of 380V delta connection, can realize electrothermal tube arrangement of the present utility model and wiring construction.
