Abstract

The utility model relates to an efficient electric water heater, in particular to a home-use electric water heater, which comprises a shell with a stent and a shell cover. An elbow pipe arranged on the shell stent is formed from the muff coupling of a plurality of quartz glass straight pipeline sections and a plurality of silica gel syphon sections, wherein the outer wall of the quartz glass straight pipeline section is in splicing with a heating membrane. The outer surface of both end parts of the heating membrane are respectively pasted with the conductive membranes, while two part conductive membranes are respectively jacketed with a conductive copper bar. Thus the water container and the insulation facility of the water container are not required. With a small size and low power consumption, the utility model is in isolation with the water channel at the same time, which is safe and reliable to use.

Description

Efficient electric water heater

The utility model relates to a kind of electric heater, especially refers to the electric heater that family uses.

At present, common water heater has two kinds: a kind of is gas heater, can only could use in the city that has fuel gas supply and running water to supply with, and being connected and also more complicated is installed of gas heater and gas-fired equipment; A kind of is electric heater, utilizes electrical bar heating mostly, and is behind the water preheat, and this hot water enters in the tank for use, and not only volume is big, and heat is constantly lost, causes the waste of electric power.

In view of this, the purpose of this utility model provides a kind of efficient electric water heater, and the conductive heating layer energising to paste on the bending quartz glass tube outer wall is constantly heated the water in this pipe, and directly supplied with hot water incessantly.

The purpose of this utility model is achieved in that and comprises housing and the cap with support, on the support of housing, do not put the bending pipe, this bending pipe is to be socketed to form by several quartz glass straight lengths and several silica gel bend loss, bonding heating film on the quartz glass straight length outer wall wherein, paste conducting film respectively in the appearance of this heating film two-end part again, and on these two sections conducting films, distinguish sheathed conducting copper.

Described bending Guan Yiduan connects a water inlet pipe, and the other end connects an outlet pipe.

Described silica gel bend loss is the flexible pipe that is socketed in two adjacent quartz glass straight length terminations.

Because adopt such scheme: do not need tank and lagging facility thereof, not only volume is little, and power saving, while and aquaporin are isolated, and be safe and reliable.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model exemplary embodiments cross-sectional schematic.

Fig. 2 the utility model exemplary embodiments power control circuit and aquaporin schematic diagram.

Among the figure: 1, housing, 11, support, 2, cap; 3, bending pipe, 31, the quartz glass straight length, 311, heating film; 312, conducting film, 313, conducting copper, 32, the silica gel bend loss; 33, water inlet pipe; 331, hydraulic pressure protector, 34, outlet pipe, 4, power control circuit; 41, earth leakage protective device, k, switch.

Present embodiment comprises housing 1, cap 2, bent pipe 3 and power control circuit 4, as shown in Figure 1, 2, and wherein:

Housing 1 and cap 2 are all metal shell, complement each other to form the rectangular box body of a sealing, belong to prior art; Two row's supports 11 are set, for supporting upper and lower two row's bending pipes 3 on housing 1 base plate.

Bending pipe 3 is to be formed by connecting by several quartz glass straight lengths 31 and several silica gel bend loss 32, wherein: quartz glass straight length 31 is transparent rigid pipes heat-resisting, electric insulation, bonding heating film 311 (as: resistive films on its pipe outer wall, resistance is 220 ohm, have more weak electric conductivity and stronger conduction effect, reach more than 90%), also stick on one deck conducting film 312 (as: aluminium film in heating film 311 appearances of pipe end positions, be commonly called as masking foil, have good electrical conductivity), sheathed conducting copper 313 (bend form with scale copper) on this conducting film 312 again.

Silica gel bend loss 32 is adiabatic flexible pipes, is convenient to adjacent quartz glass straight length 31 terminations of socket two, and can reduce the thermal loss of hot water in the pipe, and is supported on the support 11 of housing 1 with the end of the silica gel bend loss 32 of bending pipe 3.

End at this bending pipe 3 connects a water inlet pipe 33 again; cooling water enters (pressing the direction of arrow among Fig. 2); also be connected in series a hydraulic pressure protector 331 on it; in case when stopping into cold water; this hydraulic pressure protector 331 can be cut off the electricity supply automatically; so that do not damage main body (genus prior art), and the other end of bending pipe 3 connects an outlet pipe 34, can flow out for continual hot water.

Power control circuit 4 is provided with earth leakage protective device 41 and switch k (genus prior art); one end O connects a conducting copper 313 with earth leakage protective device 41 outputs; and other end N connects another conducting copper 313 through hydraulic pressure protector 331; make conducting weak current on the heating film 311; produce fuel factor, promptly the water in the quartz glass straight length 31 directly is heated.

In sum:

Efficient electric water heater of the present utility model, need only at power connection in 8 seconds, outlet pipe just can output water temperature 30 ℃～80 ℃ hot water, directly supply with and use, and do not need tank, not only volume is little, and do not need preheating, the loss of insulation, so save the energy about 35% than existing electric heater; Structurally conducting element and current are in complete isolation again, so guarantee safety.
