Description

Adopt the vertical water storage type electric water heater of non-metal shell electrothermal tube

Technical field

The present invention relates to vertical water storage type electric water 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, 95% 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 vertical water storage type electric water heater.

Technical measures of the present invention be the water tank of vertical water storage type electric water heater by metal or nonmetal making, built with non-metal shell electrothermal tube 11, the electrothermal tube filled in water tank:

Be at metal or non-metallic pipe 5 built with heating wire 3, with magnesium oxide powder 4, metal or non-metallic pipe 5 and heating wire 3 carried out isolated insulation, at the two ends of heating wire, eduction rod 1 is installed, by outside nonmetal plug 6 protruded tube; And fix at two ends of metal or non-metallic pipe 5, become heater 9; Then heater 9 is contained in non-metallic pipe 7, and heater is fixed, become non-metal shell electrothermal tube 11; Or at metal or non-metallic pipe 5 built with heating wire 3, with magnesium oxide powder 4, metal or non-metallic pipe 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, load electrothermal tube, described 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, and there is support pads at electrothermal tube two ends; 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, first-selected quartz glass tube, no matter be blind hole pipe or straight pipe, internal heating wire has one or more, isolates, prevent short circuit between heating wire with non-metallic insulation thing 10.

The invention has the beneficial effects as follows that vertical water storage type electric water heater adopts non-metal electric heating pipe, 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 or non-metallic pipe 5, also has the electrothermal tube of non-metal shell 7;

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

Fig. 3 is the structure of the in-built electrothermal tube of blind hole non-metallic pipe, and Fig. 4 is the structure of straight-through non-metallic pipe built with electrothermal tube;

Fig. 5 to Fig. 7 is the vertical storage-type electric water heater structural representation that non-metal shell electrothermal tube is housed;

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 or non-metallic pipe 5, nonmetal plug 6, straight-through non-metallic pipe or claim shell 7, blind hole non-metallic pipe or claim shell 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, blind flange 17, mount pad 18, friction top 19.

Fig. 1 to Fig. 4 be in vertical water 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 is blind hole non-metallic pipe 8, Fig. 4 is straight-through non-metallic pipe 7, interior loading electrothermal tube, and described electrothermal tube refers to carbon fiber pipe or halide torch or non-metal shell electrothermal tube; Described metal electric heat pipe 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 and turn back to the other end.

Fig. 5 to Fig. 7 is vertical electric water heater with water tank structure chart, and water tank 15 is built with electrothermal tube 11, and its outside is water, the shell of this electrothermal tube is made up of nonmetal, and inside has heating wire and water glass to isolate, never scaling, never puncture, Fig. 5 is single water tank, and Fig. 6, Fig. 7 are double water tank.
