Abstract
The utility model discloses a safety electric heater. The utility model adopts two to three electric furnace wires which are arranged adjacently and coiled in the same direction from the same beginning on a furnace plate, so that no potential difference is between the adjacent electric furnace wires and no partial short circuit is resulted from sundries falling in the furnace. The utility model has simple structure, and easy operation, and can not increase fabrication cost.
Description
The utility model belongs to consuming device, is specifically related to a kind of civilian electric furnace.
The electric furnace that uses mostly is to adopt coiling electric furnace heating wire formation on the stone or metal plate for standing a stove on as a precaution against fire at present, adds certain voltage at the electric furnace heating wire two ends, can make electric furnace heating work done.Because the groove of coiling electric furnace heating wire is at a distance of nearer on the stone or metal plate for standing a stove on as a precaution against fire, common disk is around the electric furnace of mode, all exist potential difference between the electric furnace heating wire in the adjacent trenches, so in using electric process, when having foreign material (the charcoal ash below for example various cookers, dirt, oxide and metal fillings etc.) to fall in the stove, more easily cause partial short-circuit, cause reducing electric furnace service life, electrification is used in also can causing of having.
The purpose of this utility model provides a kind of Safety electric heater that can reduce the electric furnace heating wire partial short-circuit between the adjacent trenches.
For achieving the above object, the solution that the utility model adopts is: Safety electric heater comprises stone or metal plate for standing a stove on as a precaution against fire and electric furnace heating wire, be covered with the equally spaced groove of laying electric furnace heating wire above the stone or metal plate for standing a stove on as a precaution against fire, electric furnace heating wire is coiled in the groove of stone or metal plate for standing a stove on as a precaution against fire, the utility model adopts 2-3 root electric furnace heating wire, and the initiating terminal of this 2-3 root electric furnace heating wire is in the same position of stone or metal plate for standing a stove on as a precaution against fire edge, and electric furnace heating wire is contained on the stone or metal plate for standing a stove on as a precaution against fire in the adjacent grooves successively, equidirectional coiling, and end at another location on the stone or metal plate for standing a stove on as a precaution against fire jointly.The initiating terminal of this 2-3 root electric furnace heating wire connects the live wire of power supply respectively through switch, the other end connects the zero line of power supply jointly.
Electric furnace by above scheme making, because the each point current potential of electric furnace heating wire is equal substantially in the adjacent trenches, so when foreign material are costed, also not having electric current passes through, can significantly reduce with the stove silk partial short-circuit phenomenon in the electric process, thereby can prolong the service life of electric furnace, avoid with electrification and economic loss.The utility model is simple in structure, and implementing does not increase cost of manufacture easily.
Further specify structure of the present utility model below in conjunction with drawings and embodiments.
Fig. 1 is a structural representation of the present utility model.
The circular stone or metal plate for standing a stove on as a precaution against fire that the electric furnace pan 1 of embodiment adopts refractory insulating material to make, two electric furnace heating wires 2 and 3 initial by the same position of stone or metal plate for standing a stove on as a precaution against fire 1 periphery are placed in ecto-entad coiling in first, second groove of the outside respectively, and the other end finishes near stone or metal plate for standing a stove on as a precaution against fire 1 center of circle.The initiating terminal of electric furnace heating wire 1 and electric furnace heating wire 2 inserts the live wire of 220 volts AC powers respectively through K switch 1 and K2, the zero line of electric furnace heating wire 2 and 3 other end access power supply.
Claims (1)
- A kind of Safety electric heater, comprise stone or metal plate for standing a stove on as a precaution against fire and electric furnace heating wire, be covered with the equally spaced groove of laying electric furnace heating wire above the stone or metal plate for standing a stove on as a precaution against fire, electric furnace heating wire is coiled in the groove of stone or metal plate for standing a stove on as a precaution against fire, it is characterized in that adopting 2-3 root electric furnace heating wire, the initiating terminal of this 2-3 root electric furnace heating wire is in the same position of stone or metal plate for standing a stove on as a precaution against fire edge, electric furnace heating wire is contained on the stone or metal plate for standing a stove on as a precaution against fire in the adjacent grooves successively, equidirectional coiling, and end at another location on the stone or metal plate for standing a stove on as a precaution against fire jointly, the initiating terminal of electric furnace heating wire connects power firestreak, another termination zero-power line through switch respectively.
