The specific embodiment

Below in conjunction with drawings and Examples in detail the utility model is described in detail.

Shown in Fig. 1-4; a kind of full-automatic instant electric water heater; comprise by shell 1; heating component 3 in the shell chamber; assembly heat-insulation layer 2; water inlet pipe 6; pipe joint 4; water flow switch 5 between water inlet pipe 6 and the pipe joint 4; outlet pipe 7; the magnetic valve 802 of outlet pipe 7; cooling-water temperature sensor 803; power connection 10 on the shell; last tuning knob 11; release knob 12; following tuning knob 13 reaches and magnetic valve 802; water flow switch 5; cooling-water temperature sensor 803; temperature display controller 801; multiple detection and protection apparatus for leakage 804; computer control panel 8 that overtemperature protection system 805 links and VFD display screen 9 constitute; its heating component 3 outer copper pipe 301 of serving as reasons; copper heating rod 303 in the copper pipe; be enclosed within the copper fin 304 on the heating rod 303 and the plastic spacer 302 of copper pipe end and be assembled into, the copper fin 304 that is enclosed within on the copper heating rod 303 is provided with for equidistant.Because metallic copper has that heat conductivility is strong, the thermal efficiency is high, anti-Zhang Xingqiang, corrosion-resistant, high voltage bearing characteristics, therefore the heating rod that has fin can make water heating equably rapidly, after closely cooperating with the outer copper pipe that has heat-insulation layer 2, the superelevation heating efficiency of heating rod can be fully used, the heat that water is taken away is many and heat leakage is few, and the usefulness of anti-incrustation scale, sterilization is arranged.In addition, the copper pipe of employing is totally-enclosed no seam welding, and once-forming has been stopped drainage.Generally, 2-3 heating component of assembling in the casing just can be suitable for Various Seasonal weather, area use.The heat-insulation layer 2 of its heating component is made of asbestos 201 and insulating paper 202, and it helps the assembly adiabatic heat-insulation.

The course of work of the present utility model is as follows: the back is installed connects the water source, connect power supply 10 then, 12 starts of Push switch button, temperature display controller 801 demonstrates initial temperature, open by computer plate 8 control water valves 5, cold water enters in the heating component copper pipe 301 along water inlet pipe 6, copper heating rod 303 is started working, the cold water heating rod copper fin 304 of evenly flowing through when cold water covers fin 304, is taken away the superelevation heat that heating rod forms rapidly, cold water is heated, enter second group of copper pipe heating again,, the water that has heated is heated again with same mode of heating.Water by second group of copper pipe heating back outflow, its water temperature becomes about high-temperature water of about 65 by low temperature, demonstrates actual temperature by temperature display controller 801, and hot water is regulated by magnetic valve 802, flow to the water heater shower nozzle through outlet pipe 7, but carry out bathing with regard to the bather.The height of water temperature can be regulated upper and

lower accent button

11,13 on the housing face-plate as required by the bather, and its adjusting information is passed to computer control panel 8, and 3 work of control heating component reach the water temperature that is fit to the bather.Owing to adopted this mode of heating of even fin 304 on the heating rod, it is according to the difference of season temperature, territory of use, one of select in heating power 31 (1100w), 32 (2700w) or 33 (3800w) third gear of heating component 3 heating, just can reach the thermal efficiency that common 10000w electric heater just can have, thereby be suitable for general family and install and use, it has saved the energy, reduced the expense expenditure, plug and play, the user is very convenient, has saved the bathing time.When leaving water temperature surpasses 65 ℃, turn down the heating gear by overtemperature protection system 805 single-phase charactrons flickers, when treating that water temperature reduces, again under the cooperation of relay J 1-J5 and transformer B according to early stage pattern work on.In the course of the work as when following situation occurring: when heating such as anhydrous supply, faulty sensor, insulating properties reduction are not worked, by the VFD display screen 9 flicker digital E0 * warnings of computer plate control, prompting user.When the following leakage current of 25mv occurring outside heater section, at 0.1 second internal cutting off power supply, machine was no longer worked by the multiple detection and protection apparatus for leakage 804 that is provided with, and had therefore guaranteed safety and reliability.
