Abstract

Metal water tank electric water heater side heating formula blind pipe light wave electric heating tube mounting structure is on metal water tank 1's semicircular arc surface middle part mouthful, and the lid 12 of installation nonmetal or metal preparation has threaded to connect 2, electrothermal tube 6 -1 dress and in connecting 2 hole, has sealing member 4 on it, compresses tightly with nut 5, and there is nonmetal blanking cover 8 electrothermal tube 6 -1 hole outer end, and porose or clearance 11 communicates with each other with the external world on it.

Description

Metal water tank electric heater heater-type blind pipe Optical wave electric heating tube mounting structure

Technical field

The present invention relates to electric heater, relate generally to the mounting structure of light 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, 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, is at the in-built carbon fiber of glass tube or metal heating wire, produces infra-red radiation and heat energy after energising; Below be all to electrothermal tube around water heat, be also referred to as heater-type, its mounting means is welded with metal water tank by metal sleeve, ensures water tank pressure-bearing, and by electrothermal tube by mounting mat, be placed in sleeve pipe, find following defect in practice:

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; Simultaneously can 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 improve for above-mentioned defect, eliminate the shortcoming produced completely; Technical measures of the present invention are: on the semi-circular arc Middle face mouth of existing metal water tank 1, install on lid 12 that nonmetal or metal makes, it there is the joint 2 of threaded (comprising inside/outside screw thread), electrothermal tube 6, be contained in the endoporus of joint 2, have seal 4, compress with nut 5, guarantee seal 4, make water tank water-tight; Be characterised in that: the lid installing electrothermal tube 6 makes of nonmetal or metal material, with thermometric and the warm probe mounting holes of limit; In electrothermal tube 6, outer end of hole has nonmetal blanking cover 8, and porose or gap 11 on it, the air be heated communicates with the external world.

The invention has the beneficial effects as follows existing metal water tank electric heater, install electrothermal tube by present patent application and need not carry out the water heater that any repacking just can become infrared radiation heating, electrothermal tube can not corrode and punctures, also can not scaling.

Accompanying drawing explanation

Fig. 1 Fig. 2 is blind pipe semi-conductor electricity heat pipe scheme of installation (Fig. 1 is vertical, and Fig. 2 is horizontal) in the middle part of water tank;

Fig. 3 is the tilting schematic diagram of electrothermal tube;

Fig. 4 Fig. 5 is outside electrothermal tube, and closed or semi-open-type cover are housed, and realizes fast hot schematic diagram;

Detailed description of the invention

In accompanying drawing, water tank 1, threaded joint 2, seal 4, nut 5, electrothermal tube 6 (comprising semi-conductor electricity heat pipe or luminous energy electrothermal tube), nonmetal blanking cover 8.Thermometric or the lid 12 limitting warm pipe 9, air 10, hole or gap 11, nonmetal or metal to make, semi-open-type cover 13, sealed tube 14, water inlet or outlet pipe 15.

Fig. 1 is vertical water tank, and Fig. 2 is horizontal water tank; Blind pipe semiconductor heating electrothermal tube 6, is be contained in the hole of the lid 12 that nonmetal or metal makes, realizes installing firmly and sealing with nut 5 press seal part 4; The lid 12 that described nonmetal or metal makes, apart from outside electrothermal tube 6 installation position it on, also has thermometric or limits warm pipe 9 (install in it and pop one's head in) also can arrange Inlet and outlet water joint; Due to complex structure, with nonmetal making as well, adopt metal material cost of manufacture high.

The hole of Fig. 3 joint 2 is oblique, and electrothermal tube is tilting, can increase and hot water amount; Described blind pipe refers to that one end is closed, and the other end opens wide.

Fig. 4 has a sealed tube 14 outside electrothermal tube 6, and is provided with water inlet and delivery port, is that delivery port is connected with water nozzle from water tank upper water inlet.

Fig. 5 is in electrothermal tube 6 upper outside, is provided with semicircle semi-open-type cover 13, lower open, and the water of electrothermal tube heating delivers to top by pipe 15, immediately releases; Fig. 3 and Fig. 4 structure can be selected mutually.

Described nonmetal blanking cover 8, for installing wiring and terminal, and porose 11 make to be communicated with outside air in electrothermal tube.
