Abstract
The utility model relates to electric water heater structure, in particular to improved electric water heater water tank heating structure. The heater structure is characterized in that an electric heating member is arranged outside a water container which is set to be a serpentine tube, the electric heating member is arranged in a 'U'-shaped clearance outside the serpentine tube, the electric heating member is a PTC heating unit, the cross section shape of the 'U'-shaped clearance is a rectangular flat tube which is internally provided with strengthening ribs along the tube direction, and the number of the strengthening ribs is not less than 1. An external electric heating device of the embodiment of the utility model is arranged in the electric water heater, thereby not only fundamentally stopping the safety hazard as a result of electricity leakage, but also having the characteristics of large heat exchange area, high heat efficiency, no scale formation, energy conservation and long service life. The electric water heater structure has reasonable structure and beneficial improvement.
Description
Technical field
The utility model relates to the structure of electric heater, and particularly relevant a kind of improved electric heater water tank adds thermotectonics.
Background technology
The water tank in the existing electric heater and the structure of heating part thereof are to adopt heater element is arranged at structure among the water tank substantially.No matter electric heating device is to select electrical bar, Electric radiant Heating Film or other heater element for use, and its topmost weak point is easily to leak, easily fouling, perishable, the processing technology complexity of the water tank of stainless steel, and cost is higher.After corrosion or fouling take place calandria, can produce that electrothermal efficiency reduces or produce potential safety hazard because of electric leakage.
The utility model content
The purpose of this utility model is, for at the bottom of overcoming existing electric heater electrothermal efficiency, the defective of perishable, easy fouling, and propose a kind of electric heating device to be placed the novel thermotectonics that adds outside the water tank, the utility model adopts following technical scheme to be achieved: a kind of improved electric heater water tank adds thermotectonics, comprise water receptacle and electric heating part, it is characterized in that electric heating part is located at outside the water receptacle, water receptacle is arranged to coiled pipe, be provided with electric heating part in " U " shape gap outside the coiled pipe, electric heating part is the PTC heater; The section configuration of coiled pipe is set to the flat tube of rectangle, be provided with in the flat tube along pipe to reinforcement, the number of reinforcement is no less than 1.
The electric heating device of the external that this programme is implemented is installed on electric heater, not only can stop the potential safety hazard that produces because of electric leakage up hill and dale, and have that heat exchange area is big, the thermal efficiency is high, the characteristics of non-scaling, energy-conservation and long service life.The utility model is rational in infrastructure, is a kind of useful improvement.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is that the E of coiled pipe 1 among Fig. 1 is to enlarged diagram.
The specific embodiment
Be described in further detail in conjunction with the accompanying drawings.Water receptacle in the present embodiment, by be provided with 4 along pipe to reinforcement 11 rectangular tube that constitutes 5 passages be bent into coiled pipe 1, in " U " of coiled pipe 1 shape gap, be provided with a kind of commercially available finished product device---PTC heater 2.The PTC heater is a kind of novel insulation thermostatic heater spare, only need draw two leads, 6 access power supplys and get final product heat production.That this device has is simple in structure, easy to use, power stability, the flames of anger, safe and reliable, economize on electricity, the life-span is long and working voltage is wide characteristics.Because heater members is located at outside the water body, be that PTC heater 2 does not contact with water in the coiled pipe 1 fully, so, the corrosion and the structure problem of heater avoided thus fully, also therefore prevent the potential safety hazard of electric leakage, and therefore prolonged the service life of water heater.During use, water is entered in the pipe by water inlet 10, when in coiled pipe 1, making a circulation to flow, be switched on the heat heating that the PTC heater 2 of power supply is produced, as long as this structure is turn-on current, water in the pipe can be heated, that is to say that well below the heat time heating time of existing tubular water tank the thermal efficiency of the present utility model is higher than the tubular cisten mechanism of internal heater its heat time heating time.For guaranteeing the safe operation of water pipe; be provided with the control circuit 5 that comprises dropout type temperature protector 3 and Fuse Type temperature protector 4; dropout type temperature protector 3 is bimetal leafs; when temperature is higher than the water temperature (as 75 °) of setting; circuit is opened and cut off to bimetal leaf because of the bending of being heated, to prevent scald.Otherwise, promptly connect circuit after the bimetal leaf cooling closure and continue heating.And Fuse Type temperature protector 4 is devices of a similar fuse, and when temperature was higher than 120 °, fuse was promptly by the scaling loss water pipe that fuses to prevent dry combustion method.
Claims (6)
1, a kind of improved electric heater water tank adds thermotectonics, comprises water receptacle and electric heating part, it is characterized in that electric heating part is located at outside the water receptacle.
2, add thermotectonics by the described improved electric heater water tank of claim 1, it is characterized in that water receptacle is arranged to coiled pipe, coiled pipe is provided with electric heating part in outer " U " shape gap.
3, add thermotectonics by claim 1 or 2 described improved electric heater water tanks, it is characterized in that electric heating part is the PTC heater.
