Abstract

Direct light wave electrothermal tube mounting structure of nonmetal water tank electric water heater heater -type, in two semi -circular cambered surfaces of nonmetal water tank 1, the system has threaded to connect 2, with 3 dresses of metal sleeve in connect 2 hole with the axle center, there is sealing member 4 at both ends, consume 5 with the spiral shell and compress tightly, 6 both ends of electrothermal tube have mica sheet 7 and non - metal support 8 to install in the air in the metal sleeve 3, glass manages 9 electrothermal tube 6 and metal sleeve have the one deck between 3 in the middle of, metal sleeve 3 and middle glass pipe between 9 the gapped hot -air that receives can flow, the mica sheet 7 and the porose or clearance of non - metal support 8 at 6 both ends of electrothermal tube communicate with each other with the outside air.

Description

Nonmetal water-tank electric water heater heater-type leads directly to Optical wave electric heating tube mounting structure

Technical field

The present invention relates to electric heater, relate generally to the mounting structure of optical wavelength radiation heating electrothermal tube.

Background technology

The patent of invention of Chinese Guangdong Shuande Guang Sheng electrical equipment limited company numbers 200810091347.6 and patent application 2009101315082.X are electric heating tube side heat type heating.

Another number of patent application 201510261254.3 Optical wave electric heating tube has two kinds: one to be semi-conductor electricity heat pipe 6-1, be by semiconductor heating material, be coated in glass tube inner wall surface, form one deck conducting film, and have binding post, infra-red radiation and heat energy can be produced after energising; Two is luminous energy electrothermal tube 6-2, at the in-built carbon fiber of glass tube or metal heating wire, produce infra-red radiation and heat energy after energising: be all above to electrothermal tube around water heat, also heater-type is referred to as, its mounting means is welded with metal water tank by metal sleeve, ensures water tank pressure-bearing, and electrothermal tube is passed through mounting mat, be placed in sleeve pipe, in practice, find following defect:

1. because electrothermal tube is glassware, long again, in long-distance transport, electrothermal tube glass breakage occurred, and heating wire still can be energized work, likely make water-band electricity by metal sleeve; Meanwhile, meeting scaling;

2. mounting mat is for a long time by after high warm, and produce carbonization, electrothermal tube departs from center, produces displacement;

3. two ends sealing, expands after inner air heating, is squeezed by mounting mat, even draw bad electrothermal tube.

Summary of the invention

The object of the invention is to propose improvement project for above-mentioned defect, eliminate the shortcoming found completely; Technical measures are: water tank adopts non-metallic plastic material, make by blowing or Shooting Technique; In two semicircle cambered surfaces of nonmetal water tank 1, be shaped with joint or flanged (FLGD) joint 2 of threaded (comprising inside/outside screw thread), by metal sleeve 3, be contained in the endoporus of coaxial fitting 2, there is seal 4 at two ends, compress, guarantee that seal 4 makes water tank 1 water-tight with nut or lid 5; Electrothermal tube 6 has mica sheet 7 and non-metal frame 8 by two ends, is arranged in the air in metal sleeve 3; One deck intermediate glass pipe 9 is had between electrothermal tube 6 and metal sleeve 3; Have gap between metal sleeve 3 and intermediate glass pipe 9, two ends high-temperature seal adhesive clings, but do not stop two-layer between be heated after air flowing; The mica sheet 7 at electrothermal tube 6 two ends and non-metal frame 8 is porose or gap, communicates with outside air; Useable glass pipe alternative metals sleeve pipe 3, then do not need glass tube 9, and to be electrothermal tube 6 be another feature is contained in when filling water in air 11 in water tank 1, can take out or install.

The invention has the beneficial effects as follows that heating wire is contained in glass tube that electrothermal tube integral installation is in air 11, also have one deck glass tube outside electrothermal tube, security is very high; Simultaneously when electrothermal tube damages, also replaceable when filling water in water tank.

Accompanying drawing explanation

Fig. 1 is the water tank schematic diagram being welded with joint;

Fig. 2 is the liner for water tank of water heater structure chart that electrothermal tube is housed;

Fig. 3 Fig. 4 is the Local map of Fig. 1 Fig. 2 joint;

Detailed description of the invention

In accompanying drawing, water tank 1, there is screw thread or have the joint 2 of flange, metal or non-metallic casing 3, seal 4, nut or lid 5, electrothermal tube 6 (semi-conductor electricity heat pipe 6-1, luminous energy electrothermal tube 6-2), mica sheet 7, non-metal frame 8, intermediate glass pipe 9, air 11.

In Fig. 1 Fig. 2, described straight-through Optical wave electric heating tube refers to and arbitrarily can insert from two ends, has screw thread for this reason or has the joint 2 of flange, on two semicircles, must keep concentric, guarantee that metal sleeve 3 installation site is correct, by nut 5, seal 4 is compressed, make tank seal; Position and the quantity of joint set on demand.

Described metal sleeve or glass bushing 3 can be selected, and are all to be sleeved on outside electrothermal tube 6, and when adopting metal sleeve 3, between metal sleeve 3 and electrothermal tube 6, dress intermediate glass pipe 9 improves security, does not fill intermediate glass pipe 9 also within this patent protection; If directly with glass bushing 3, require the wall thickness > 2mm of glass bushing 3; When this mounting means electrothermal tube damages, do not discharge water, i.e. replaceable electrothermal tube.

Described mica sheet 7 can play the heat insulation and effect of centering.

Described water tank 1 comprises horizontal or vertical, comprises single barrel or twin-tub.

Described electrothermal tube 6 is one or more.
