Existing electric heater divides two kinds, and a kind of is storage-type displacement type electric heater, and a kind of is quick-heating type electric water heater; Family of the less relatively suitable domestic consumer of storage-type electric water heater power demand, but volume is bigger, heat time heating time is long, and user's stand-by period of having a bath is also just long more, particularly big volume storage-type electric water heater product.Little volume storage-type electric water heater is shorter heat time heating time, and the same bathing time is also shorter.Quick-heating type and quick-heating electric water heater while heat bathing, do not need the stand-by period, and volume are small and exquisite, but only are suitable for the certain customers of coincident circuit requirement because power is bigger, on one side and one side water outlet heat and have potential safety hazard.For solving an above difficult problem, a kind of water outlet is fast all puted forth effort to develop by many producers, energy-conserving and environment-protective again, the electric heater that is suitable for the ordinary consumer demand, adopt the top layer heating method of heater as some producers around outlet pipe, this method is the frame mode that adopts around outlet pipe around heater, utilize Fast Heating outlet pipe top warm water on every side, so that storage-type electric water heater is realized the temperature fast lifting, though this method has reached energy-conservation and the requirement fast lifting hot water temperature, owing to adopt heater to be looped around outlet pipe structure on every side, during installation or after long-time the use, can cause owing to the distortion of outlet pipe and produce interference with heater, in addition, for considering safety factor, the outlet pipe of part producer adopts the structure of plastic tube, because it is bigger around the heater power of outlet pipe, heater is with after outlet pipe contacts, and outlet pipe can be because delivery port be blocked in thawing, when intake pressure is excessive, inner bag will be burst, even the danger that can blast.
The utility model content:
The purpose of this utility model is to consider the problems referred to above and a kind of electric heater is provided.The utility model is not only saved the space, cost is low, safe in utilization, easy to operate, long service life.
The technical solution of the utility model is: include inner bag, be fixed on water inlet pipe, outlet pipe and main heating tube on the inner bag, wherein main heating tube is contained in the bottom of inner bag hollow cavity, wherein the side around the water inlet of outlet pipe or the bottom be provided with the hot water that inner bag is in keeping warm mode carry out post bake and with the discontiguous secondary heating tube of outlet pipe.
Above-mentioned secondary heating tube is done curl or is managed bar-shapedly, and it places the side around the bottom of water inlet of outlet pipe.
The side of above-mentioned secondary heating tube is provided with thermostat.
Above-mentioned secondary heating tube and thermostat are fixed on the inner bag by flange.
Above-mentioned main heating tube also is fixed on the inner bag by flange.
The water inlet of above-mentioned water inlet pipe is provided with water flow sensing unit; Or the delivery port of outlet pipe is provided with water flow sensing unit.
Above-mentioned secondary heating tube is connected with the water-electricity linkage device of electric heater.
Above-mentioned water-electricity linkage device is served as reasons on the water inlet that is arranged on water inlet pipe or is arranged on the relay of the water flow sensing unit control on the delivery port of outlet pipe.
What kind of mounting means is the utility model therefore, adopt can not have interference with outlet pipe regardless of secondary heating tube owing to adopt secondary heating tube and the discontiguous structure of outlet pipe, thereby guarantee that the user's is safe in utilization.The utility model is simple in structure, and is safe in utilization, efficiency of heating surface height, hot water delivery rate height, conserve energy.The utility model is that a kind of design is ingenious, function admirable, convenient and practical electric heater.
