Central air conditioning electricity auxiliary heater who has electrothermal tube of heating wire in non -metallic pipe is equipped with, the shell of used electrothermal tube is non -metallic material, 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), are equipped with heating wire (3), and magnesia or nonmetal insulating thing or air (4) are drawn stick (1) and are stretched to the outside of tubes through nonmetal end cap (6) in addition, heating wire (3) are dry combustion methods in the air of dress in non -metallic pipe (7) or (8), open the end lower part in direct non -metallic pipe (7) or blind hole non -metallic pipe (8) simultaneously, be equipped with circuit breaker (12), the circuit breaker is that one end is two exposed and keep apart wires, and the other end and control circuit board's controlling element is connected, meets water simultaneously when two wires and switches on, just infories controlling element, and messenger's circuit breaks off.

Description

The central air-conditioning electric heating device of the electrothermal tube having heating wire is housed in non-metallic pipe

Technical field

The present invention relates to central air-conditioning electric heating device, relate generally in central air-conditioning electric heating device, adopt the electrothermal tube having heating wire in the non-metallic pipe that is immersed in water.

Background technology

Existing for the electrothermal tube in central air-conditioning electric heating device, 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 electric heating element generally used; This metal shell electric heating element, is fully immersed in water, and after long-time use, meeting scaling, reduces heating efficiency, and corrosion punctures, and makes water-band electricity; And to water softening device be supported the use.

Summary of the invention

The object of the invention is to improve existing central air-conditioning electric heating device.

Technical measures of the present invention are that the water tank of central air-conditioning electric heating device is by metal or nonmetal making, electrothermal tube 11 built with there being heating wire in non-metallic pipe: be built with heating wire 3 and magnesium oxide powder or air 4 at straight-through non-metallic pipe 7, and heating wire 3 is fixed in non-metallic pipe 7, eduction rod 1 is installed by nonmetal plug 6 at the two ends of heating wire, outside protruded tube, become in non-metallic pipe the electrothermal tube 11 having heating wire; Or at one end close and become blind hole non-metallic pipe or shell 8 built with heating wire 3 and magnesium oxide powder or air 4; By nonmetal plug 6, the blind hole non-metallic pipe other end is blocked, at the two ends of heating wire 3, eduction rod 1 is installed, and heating wire 3 is bent to U-shaped, make two eduction rods 1 at one end, by outside nonmetal plug 6 protruded tube, become in non-metallic pipe the electrothermal tube 11 having heating wire; Described heating wire 3 is dry combustion methods in air in non-metallic pipe 7 or 8.

For realizing double insulation, one deck non-metallic pipe can be set again between heating wire 3 and non-metallic pipe 7 or 8.

Simultaneously in straight-through non-metallic pipe 7 or blind hole non-metallic pipe 8 open end bottom, circuit breaker 12 is housed, described circuit 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 central air-conditioning electric heating device adopts in non-metallic pipe the electrothermal tube having heating wire, to be immersed in water not scaling, electric heating element corrodes never and punctures, and can not leak electricity.

Accompanying drawing explanation

Fig. 1 is that two ends have eduction rod, has the electrothermal tube of heating wire in non-metallic pipe;

Fig. 2 to Fig. 4 is that one end has eduction rod, has the electrothermal tube of heating wire in blind hole non-metallic pipe;

Fig. 5 is the central air-conditioning electric heating device of existing metal electric heat pipe;

Fig. 6 Fig. 7 is the structural representation of the central air-conditioning electric heating device that the electrothermal tube having heating wire is housed in non-metallic pipe;

Embodiment

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 7, blind hole non-metallic pipe or claim shell 8, heater 9, non-metallic insulation spacer 10, non-metal shell electrothermal tube or metal electric heat pipe 11, circuit breaker 12, metal or nonmetal water tank 15, shell 16.

Fig. 1 to Fig. 4 be in central air-conditioning electric heating device one end of filling or two ends have the electrothermal tube having heating wire in the employing non-metallic pipe of eduction rod, there is nonmetal plug 6 termination, eduction rod 1 is by outside plug 6 protruded tube, there is the heating wire 3 of heating wire in non-metallic pipe, between heating wire, have non-metallic insulation thing 10 isolated; In non-metallic pipe, the diameter having magnesia powder or non-metallic insulation thing or air 4, Fig. 4 heating wire often to enclose is comparatively large, heating wire can be pressed close to tube wall.

Because heating wire 3 can dry combustion method in atmosphere, therefore can directly be contained in non-metallic pipe, if when filling with magnesia powder, the position of heating wire can not be moved.

Fig. 6 Fig. 7 is the structural representation of the central air-conditioning electric heating device described by present patent application, central air-conditioning electric heating device power has several kilowatts to tens kilowatts, the quantity of electrothermal tube is many, can horizontal dress or perpendicular dress, 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, inside has heating wire and water glass to isolate, and never scaling, never punctures.
