Adopt horizontal couple of courage water storage formula electric water heater of non -metal casing electrothermal tube, the shell of used electrothermal tube are the non -metallic material preparation, and its one end or two ends have the stick of drawing (1), are in through type or blind hole non -metallic pipe (7) or (8) is equipped with the electrothermal tube in, and draw stick (1) and stretch to the outside of tubes through nonmetal end cap (6), the electrothermal tube is carbon fiber electrothermal tube or halogen electrothermal tube or non -metal casing electrothermal tube or dry combustion method electrothermal tube, it is equipped with circuit breaker (12) to open one end at the non -metal casing electrothermal tube simultaneously.

Description

Adopt horizontal pair of courage storage-type electric water heater of non-metal shell electrothermal tube

Technical field

The present invention relates to electric heater, relate generally in electric heater, the non-metal shell electrothermal tube be immersed in water adopted.

Background technology

Existing for the electrothermal tube in electric heater, 100% is the tubular electrothermal element produced by technical standard JB/T4088-1999 " daily tubular electrothermal element " or JB/T2379-1993 " tubular metal electric heating element ", be " take metal tube as shell, heating alloy make heater; at one end or two ends have eduction rod; in metal tube, load closely knit magnesium oxide powder dielectric, with the element of fixing heater; " be the existing heating generally used; This metal shell heating, is fully immersed in water, and after long-time use, meeting scaling, reduces heating efficiency, and corrosion punctures, and making water-band electricity, is world-famous puzzle.

Summary of the invention

The object of the invention is to improve existing horizontal pair of courage storage-type electric water heater.

Technical measures of the present invention are: water tank is by metal or nonmetal making, built with non-metal shell electrothermal tube 11: be built with heating wire 3 at metal tube 5, with magnesium oxide powder 4, metal tube 5 and heating wire 3 are carried out isolated insulation, at the two ends of heating wire, eduction rod 1 is installed, by outside nonmetal plug 6 protruded tube, become heater 9; Then heater 9 is contained in non-metallic pipe 7, and non-metallic pipe two ends and heater are fixed, become non-metal shell electrothermal tube 11; Or at metal tube 5 built with heating wire 3, with magnesium oxide powder 4, metal tube 5 and heating wire 3 are carried out isolated insulation, at the two ends of heating wire 3, eduction rod 1 is installed, and bends to U-shaped, make two eduction rods at one end, become heater 9, then heater 9 is contained in one end close become in blind hole non-metallic pipe 8, in unlimited one end, non-metallic pipe 8 and heater 9 are fixed, become non-metal shell electrothermal tube 11; Or in blind hole non-metallic pipe 8, loading electrothermal tube described in electrothermal tube is carbon fiber pipe or halide torch or non-metal shell electrothermal tube or dry combustion method electrothermal tube, and by the eduction rod 1 in blind hole one end, bending turning back to the other end makes eduction rod in same one end, becomes non-metal shell electrothermal tube.

Simultaneously, in straight-through non-metallic pipe 7 or blind hole non-metallic pipe 8 open end bottom, breaker 12 is housed, described breaker, to be one end be two exposed and wires of isolation, the other end is connected with the control element of control circuit board, when two one metal wires run into water conducting simultaneously, just notify control element, circuit is disconnected.

Described non-metallic pipe 7 or 8, no matter first-selected quartz glass tube is blind hole pipe or straight pipe, and what inside filled is electrothermal tube, reaches double insulated standard.

The invention has the beneficial effects as follows that the horizontal pair of courage storage-type electric water heater adopts non-metal shell electrothermal tube, to be immersed in water not scaling, heating corrodes never and punctures, and can not leak electricity.

Accompanying drawing explanation

Fig. 1 is that two ends have eduction rod, outside metal tube 5, also has the electrothermal tube of non-metal shell 7;

Fig. 2 is that one end has eduction rod, outside metal tube 5, also has the electrothermal tube of blind hole non-metal shell 8;

Fig. 3 Fig. 4 is that blind hole non-metal shell 8 and straight-through non-metallic pipe 7 are built with electrothermal tube;

Fig. 5 Fig. 6 is the horizontal pair of courage storage-type electric water heater structural representation that non-metal shell electrothermal tube is housed, and Fig. 6 can fast hot water outlet;

Detailed description of the invention

In accompanying drawing, eduction rod or claim terminal 1, sealing ring or high-temp glue 2, heating wire 3, magnesia powder or non-metallic insulation thing or air 4, metal tube 5, nonmetal plug 6, straight-through non-metallic pipe 7, blind hole non-metallic pipe 8, heater or claim electrothermal tube 9, non-metallic insulation spacer 10, non-metal shell electrothermal tube 11, breaker 12, metal or nonmetal water tank 15, shell 16, the out-of-date i.e. water-heating device 17 of current, have the container 18 of intake-outlet.

Fig. 1 to Fig. 4 be in horizontal pair of courage storage-type electric water heater one end of filling or two ends have the employing non-metal shell electrothermal tube of eduction rod, there is nonmetal plug 6 termination, and eduction rod 1 is by outside plug 6 protruded tube;

Fig. 3 Fig. 4 is at blind hole non-metallic pipe 8 and straight-through nonmetal 7, interior loading electrothermal tube, and described electrothermal tube refers to carbon fiber pipe or halide torch or non-metal shell electrothermal tube; Described dry combustion method electrothermal tube refers in metal tube have heating wire, heating wire and metal pipe-wall is insulated with magnesia powder; This kind of structure, the eduction rod in blind hole one end will bend turns back to the other end;

Fig. 5 Fig. 6 is the horizontal pair of courage electric heater structural representation that non-metal shell electrothermal tube is housed, in Fig. 6, water tank is built with the out-of-date i.e. water-heating device 17 of current, be in the container 18 having intake-outlet, non-metal shell electrothermal tube 11 is housed, the out-of-date electrothermal tube 11 of current must be connected.
