Description

Adopt the electric heater in the combined cabinet of non-metal shell electrothermal tube

Technical field

The present invention relates to the electric heater in combined cabinet.

Background technology

Electrothermal tube in electric heater set in existing combined cabinet, 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 makes water-band electricity.

Summary of the invention

The object of the invention is to improve electric heater set in existing combined cabinet, at water tank 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.

Technical measures of the present invention be the water tank of electric heater in combined cabinet by metal or nonmetal making, the electrothermal tube adopted:

Be at metal tube 5 built with heating wire 3, with magnesium oxide powder 4, metal tube 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, becomes heater 9; Then heater 9 is contained in straight-through non-metallic pipe 7, and non-metallic pipe two ends and heater are fixed, have magnesium oxide powder or air 4 therebetween simultaneously, become non-metal shell electrothermal tube 11 (Fig. 1); Or at metal tube 5 built with metal or non-metal electric heating silk 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, bend to U-shaped, make two eduction rods at one end, become heater 9, then heater 9 is contained in one end to close and become in blind hole non-metallic pipe 8, between bending heating wire, has magnesium oxide powder or air 4 or insulant 10; In unlimited one end, non-metallic pipe 8 and heater 9 are fixed, become non-metal shell electrothermal tube 11 (Fig. 2); Or in the in-built electrothermal tube of straight pipe 7 or blind hole non-metallic pipe 8, load 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; Described electrothermal tube is carbon fiber pipe or halide torch, or non-metal shell electrothermal tube or dry combustion method metal electric heat pipe (Fig. 3 Fig. 4).

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, by two connecting lines, the other end is connected with the control element of control circuit board, when two one metal wires run into water simultaneously, conducting just notifies control element, and circuit is disconnected.

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

The invention has the beneficial effects as follows and adopt 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 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 is the structural representation having electrothermal tube in blind hole non-metallic pipe;

Fig. 4 is the structural representation having electrothermal tube in through type non-metallic pipe;

Fig. 5 is the electric heater structural representation be equipped with in the combined cabinet of non-metal shell electrothermal tube;

Fig. 6 to Fig. 9 is the installation method in the electric heater of non-metal shell electrothermal tube in combined cabinet;

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 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, combined cabinet 20, pond 21, tap 22, flush handle 23, toilet 24, gondola water faucet 25.

Fig. 1 to Fig. 4 be electric heater in combined cabinet one end of filling or two ends have the employing non-metal shell electrothermal tube of eduction rod.

Fig. 4 is that straight pipe 7 is interior, Fig. 3 is in blind hole non-metallic pipe 8, and load electrothermal tube, described electrothermal tube refers to carbon fiber pipe or halide torch, or non-metal shell electrothermal tube, and the eduction rod in blind hole one end will bend and turn back to the other end.

Fig. 5 is equipped with electric heater structural representation in combined cabinet, refer to and electric heater is set in the bottom, pond of combined cabinet (also known as integral cabinet), its water tank is by metal or nonmetal making, water tank 15 is built with electrothermal tube 11, and its outside is water, and the shell of this electrothermal tube is made up of nonmetal, there is heating wire inside, isolate with water glass, never scaling, never puncture.
