Description

Adopt horizontal single 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 single courage storage-type electric water heater.

Technical measures of the present invention be the water tank of horizontal single courage storage-type electric water heater by metal or nonmetal making, built with non-metal shell electrothermal tube 11; Described non-metal shell electrothermal tube refers to that the shell of electrothermal tube is that nonmetallic materials make: be built with heating wire 3 at metal or non-metallic pipe 5, 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, 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 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 bend 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, become non-metal shell electrothermal tube 11; Or at straight-through non-metallic pipe 7 or blind hole non-metallic pipe 8, interior loading electrothermal tube, described electrothermal tube is carbon fiber pipe or halide torch or non-metal shell electrothermal tube or dry combustion method electrothermal tube, 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, just notify control element when two one metal wires run into water conducting simultaneously, circuit is disconnected.

Described non-metallic pipe 7 or 8, first-selected quartz glass tube.

The invention has the beneficial effects as follows that horizontal single courage 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 that blind hole non-metal shell is interior, Fig. 4 is the structure chart of straight-through non-metallic pipe built with electrothermal tube;

Fig. 5 to Fig. 7 is horizontal single courage storage-type electric water heater structural representation that non-metal shell electrothermal tube is housed, Fig. 5 is horizontal, Fig. 6 be electrothermal tube downwards tilting, Fig. 7 be that electrothermal tube is upwards tilting;

Fig. 8 is the out-of-date i.e. water-heating devices of current;

Fig. 9 is the out-of-date i.e. water-heating devices of semi-open-type current;

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 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, the out-of-date i.e. water-heating device 20 of current, have the container 21 of intake-outlet.

Fig. 1 Fig. 2 be in horizontal single 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, eduction rod 1 is by outside plug 6 protruded tube, there is 1 or more heating wire 3 in non-metal shell, between heating wire, have non-metallic insulation thing 10 isolated; In non-metal shell, there are magnesia powder or non-metallic insulation thing or air 4.

Fig. 3 be in blind hole non-metallic pipe 8, Fig. 4 loads non-metal electric heating pipe 11 in straight-through non-metallic pipe, described non-metal electric heating pipe refers to carbon fiber pipe or halide torch or ceramic package 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 is electrothermal tube 11 horizontal, and Fig. 6 Fig. 7 is that electrothermal tube is tilting;

Fig. 8 is equipped with the out-of-date i.e. water-heating device 20 of current in water tank, be in the container 21 having intake-outlet, it is closed structure that non-metal shell electrothermal tube 11 is housed; Fig. 9 is semi-open-type structure.

In Fig. 5 to Fig. 7, two electrothermal tubes are installed, also only with an electrothermal tube, during with an electrothermal tube, only can need be arranged on the electrothermal tube of bottom; When employing two electrothermal tubes, be exactly Quick-heating electric water heater, only need top electrothermal tube work in summer, season in spring and autumn, and be namely open namely to carry out hot water; Winter, with bottom electrothermal tube preheating, makes whole box water be preheating to the temperature of sets itself, and during boiling water, bottom electrothermal tube does not work, and is heated the water flow through by top electrothermal tube again, very energy-conservation.
