Description
Technical field
The utility model relates to a kind of kitchen guarding of family electrical equipment, relates in particular to a kind of full-automatic energy-saving electric heater.
Background technology
In the existing market, the electric heater in household appliance technical field kitchen guarding's electrical equipment mainly comprises electricity separation heated type, pre-heated or solar energy type.Electricity separation mode of heating wherein is about to the heater element resistance silk, is contained in length copper tube suitable with resistance wire, adopts method and the copper pipe of filling with silica flour to insulate.The electric heater of this mode of heating, service life is not long, and have more than is needed how long just may the electric leakage caused short circuit and burnt.Reason is: one, and copper pipe is elongated, and it is inhomogeneous that silica flour is filled, and having thickly has thin, thin place insulation Strong degree low, and electricity is easy to produce electric leakage from puncturing here, if the electric leakage of two places is arranged, will produce short circuit by copper pipe; Two, heating element heater in the market is mainly U font, screwed pipe shape, vortex flow shape, their line from very close to, when leak electricity simultaneously in high voltage place and low-voltage place, will conduct electricity the generation current short circuit by copper pipe, all electric elements (such as wire, switch, socket, plug etc.) are burnt out simultaneously; Three, the silica flour of filling in the copper pipe, on the one hand will be as insulating materials, stop between the existing copper pipe of resistance wire and switch on, need it that insulating properties is arranged, the heat that by it resistance wire is produced again on the other hand conducts to copper pipe and then to water and heats, these two performances are conflicting on being reasonable in one's demand and discussing, if silica flour is too many, then affect heat conduction, the heat that causes resistance wire to produce is difficult to spread out of, the excess Temperature of resistance wire can affect its service life, if silica flour is too thin, then because silica flour at high temperature can burn agingly, reduces its dielectric strength and produce the electric leakage problem.
Preheating type namely adopts the tank about 50 ~ 80 liters to fill in advance cold water, will could use after heating a period of time with electric heater in advance when needing.This water heater, volume is large, and manufacturing, transportation, installation cost are all very high, although tank is provided with heat-insulation layer outward in addition, can't accomplish absolute insulation after all, and hot water can only be preserved one day substantially, easily caused power wastage.
The solar water heater cost is high, will wait long time that water is just arranged when putting hot water, and cloudy day, rainy day will be used electrical heating, also want timely supplementing water after being finished, heat is somewhat opposite with hot requirement for amount, when calorific requirement is few and heat supplies to measure greatly, heating load was few just when calorific requirement was large, imbalance between supply and demand.
The utility model content
The full-automatic energy-saving electric heater that provides a kind of firing rate fast, energy-conservation, safe, simple in structure is provided the purpose of this utility model.
This full-automatic energy-saving electric heater that the utility model provides, comprise the insulation heating pipe, heating element heater, insulation outlet pipe, insulation admitting pipe, live wire connection jaws and zero line connection jaws, described live wire connection jaws and zero line connection jaws are separately fixed at insulation heating pipe's two ends, described heating element heater is installed among the insulation heating pipe, its two ends are connected with live wire and the zero line of live wire connection jaws and zero line connection jaws respectively, also cover has a stainless steel tube outside described insulation heating pipe, at described zero line connection jaws one hydraulic electric switch is installed, described heating element heater comprises the resistance wire of four parallel connections, respectively is furnished with a gear on-off on this resistance wire, be provided with an intake tunnel at the live wire connection jaws, be provided with an exhalant canal at the zero line connection jaws, described insulation outlet pipe is communicated with exhalant canal, and described insulation admitting pipe is communicated with intake tunnel by a straight-through valve.
Described resistance wire adopts between different resistances and adjacent resistor silk and is provided with isolating pad.
Also comprise A.C. contactor, this A.C. contactor is installed in the loop of heating element heater.
Described insulation outlet pipe adopts the metal hose of insulation to make.
Compared with prior art, the utlity model has following advantage:
One, owing to adopting the water power mixed flow, water directly contacts with resistance wire, at first, heat transfer soon, do not need heat-insulation layer, volume with regard to little, cost is low; Secondly, the heat of resistance wire is absorbed by water immediately, causes the temperature of resistance wire can be not too high, so that lengthen the service life of resistance wire; Again, the heat of resistance wire is easily absorbed by water, makes like this resistance wire of same diameter, and the electric current that passes through can strengthen, and also just can improve power; At last, capacity is unrestricted;
Two, can not need first water storage with putting instant heating, lightweight, convenient transportation is installed simple; And owing to putting instant heating, do not need first heat tracing to do the consumption of distributing that ， Jiu No for subsequent use has heat energy, therefore very energy-conservation;
Three, owing to passing through four electric-heating-wire-heatings that power is different in the ambroin pipe, one can access a plurality of class, adds that the water yield of straight-through valve is regulated, and the water temperature adjustable range is wide.And the bucket formula, boxly turn down passablely, and but cross when low when temperature in the bucket, just heightened inconvenience; Its two, effectively reduce volume and the cost of water heater;
Four, owing to the Bian tube designs, electricity is advanced by the water inlet head end, and water outlet brings out, and adds that water is very large at plastic tube resistance, is not just depositing short circuit, only opens circuit, and has effectively protected the electrical equipment such as switch, circuit, socket, plug, can not burn because of short circuit; And because the voltage drop of resistance wire so that delivery port is exactly no-voltage, uses with regard to safety;
Five, owing to adopting hydraulic electric switch and contactor to be used in conjunction with, both realized that operation automatically, has improved again security greatly.When zero line disconnected, control circuit can't be connected, and had effectively controlled electricity and had entered water heater.Meeting autoshutdown power supply effectively prevents dry combustion method when hydraulic pressure is low, and Accident prevention occurs;
Even six resistance wires blow, earth leakage protective is malfunctioning, and the connecting to neutral line also disconnects; three kinds of situations occur simultaneously, also can be owing to the resistance value of water in the insulation heating pipe is large, also because the large effect of resistance value of water in the plastic tube; go to survey water temperature with hand, also can not get an electric shock, use safety.
