Abstract
The utility model relates to a safe electric heater and comprises an electric heated tube which is provided with an electric heated wire. The electric heated tube and the electric heated wire are insulated by filling with magnesia powder between the electric heated tube and the electric heated wire. The electric heated tube is also provided with a stainless steel outer shell. An insulated fixing frame is arranged and magnesia powder is filled between the electric heated tube and the stainless steel outer shell. A double-layer absolute insulation is realized in the utility model. The insulated performance is good and the use is safe and reliable. The utility model is mainly used on an electric shower apparatus.
Description
The utility model relates to a kind of safe electric heater, is mainly used in electric shower-bath.
Electric shower-bath has obtained applying widely for people's life provides great convenience.But, the electric leakage problem of electric shower-bath is the hot issue that people pay close attention to always, uses the corrosion pin hole of appearance easily to cause infiltration short circuit electric leakage, electric heating tube or electrical heating wire easily to cause the company's electricity between components and parts or the electric leakage or the like of breaking through expanding with heat and contract with cold repeatedly for a long time as electric heating tube.In practice, people have taked multiple mode to overcome this problem, have played security protection effect to a certain degree, but still can not fundamentally stop this hazards, and therefore, people use this series products still to have certain danger.
The purpose of this utility model is to provide a kind of good insulation preformance, electric heater that safety in utilization is good.
Safe electric heater described in the utility model, comprise the electric heating tube that electrical heating wire is housed, isolate mutually by the magnesia powder of filling between electrical heating wire and electric heating tube, its electric heating tube is set up a stainless steel casing outward, is filled with magnesia powder between electric heating tube and stainless steel casing and is provided with the isolation fixed mount.
The utility model has been realized double-deck absolute insulation isolation, and good insulation preformance is safe and reliable.
In order further to improve the insulation isolation performance, establish the insulation fixed head at the terminals of electric heater, and between insulation fixed head and electric heating tube, add thermal insulation layer, guarantee the utilance of heat.The water proof rubber plug can be set up in the insulation fixed head outside at electric heater, and rubber stopper is provided with wire hole, and the water proof rubber plug has prevented that the water that water smoke produces from flowing on the power supply wiring rod, avoided connecting electric dangerous phenomenon.
Below in conjunction with the embodiment accompanying drawing the utility model is further described.
Fig. 1, the utility model one example structure schematic diagram.
Among the figure: 1 stainless steel casing, 2 is isolated fixed mount, 3 electrical heating wires, 4 electric heating tubes, 5 thermal insulation layers, 6 insulation fixed heads, 7 conductive connection rods, 8 rubber stoppers, 9 wire holes, 10 magnesia powders.
As shown in the figure, safe electric heater described in the utility model, comprise the electric heating tube 4 that electrical heating wire 3 is housed, isolate mutually by the magnesia powder 10 of filling between the tube wall of electrical heating wire 3 and electric heating tube 4, electric heating tube 4 outer stainless steel casings 1 in addition, 1 of electric heating tube 4 and stainless steel casing are filled with magnesia powder 10 and are provided with isolates fixed mount 2.The terminals of electric heater are provided with insulation fixed head 6, add thermal insulation layer 5 between insulation fixed head 6 and electric heating tube, and insulation fixed head 6 outsides of electric heater are provided with water proof rubber plug 8, and rubber stopper 8 is provided with wire hole 9.
The utility model in use if electric heating tube goes wrong, then also has its outer field safeguard procedures, has realized double-deck absolute insulation isolation, and the setting of in addition insulate fixed head and water proof rubber plug has further improved insulation property, and is safe and reliable.
Claims (3)
1, a kind of safe electric heater, comprise the electric heating tube that electrical heating wire is housed, isolate mutually by the magnesia powder of filling between electrical heating wire and electric heating tube, it is characterized in that electric heating tube also has a stainless steel casing outward, is filled with magnesia powder and is provided with the isolation fixed mount between electric heating tube and stainless steel casing.
2, safe electric heater according to claim 1 is characterized in that the terminals of electric heater are provided with the insulation fixed head, adds thermal insulation layer between insulation fixed head and electric heating tube.
