The specific embodiment
Referring to Fig. 1~Fig. 4, electric heater of the present utility model comprises installing plate 1, buck plate 2 and organizes electric heating part 3 more; This installing plate 1 can adopt plastic plate, metallic plate or have other material plate of waterproof effect, as bamboo clappers etc.Buck plate 2 is assembled together with installing plate 1 by fastening bolt etc., for electric heater of the present utility model being assemblied in to heating container, with the water in heating container, heats; This buck plate 2 is for installing other accessory (switch etc. as will be described below) of the utility model or being assemblied in airtight water tank or container simultaneously.The groove that has cavity or pass through for wire etc. between buck plate 2 and installing plate 1, is convenient to conducting wire.This many groups electric heating part 3 is vertically contained on installing plate 1, and when easy to use, this electric heating part can stretch in the container that fills water.And be connected with external wire after this many groups electric heating part 3 is parallel with one another.By this external wire and external power supply (as with 220V alternating current) be connected, make electric heating part heating.The utility model further includes spray pipe 8, and this spray pipe 8 is assemblied on installing plate 1 and in many groups electric heating part 3 central authorities, is evenly equipped with spray-hole 81 (consulting Fig. 8) on this cleaning hose, and its spray-hole 81 injection directions are towards many groups electric heating part 3.The import of this spray pipe is positioned at outside buck plate, by import and connecting water pipe etc., is connected with external water source, after connecting external water source, can make the water in spray pipe spray from spray-hole, for rinsing the dirt on electric heating part.When particularly this electric heater is arranged on closed tank or container, can selectively incrustation scale accompanying on electric heating part be rinsed, guarantee its thermal energy conduction ability, and extend its service life.
Referring to Fig. 1, Fig. 4 and Fig. 5, described every group of electric heating part is comprised of heat-transfer pipe 31 and resistance wire 32, and resistance wire 32 is placed in heat-transfer pipe 31 (consulting Fig. 4).This heat-transfer pipe 31 is arranged on installing plate 1.In order to prevent heat-transfer pipe conduction, between resistance wire and heat-transfer pipe, there is insulating barrier, as table in heat-transfer pipe is coated with insulating barrier or resistance wire is wrapped with insulating barrier.Each is connected (consulting Fig. 5) with power switch 34 after organizing the parallel with one another and protector for connection 33 of resistance wire in electric heating part, and this power switch is connected with external power supply (generally adopting the 220V civil power in electrical network) by wire.This protector 33 and power switch 34 are arranged on buck plate (consults Fig. 1), is convenient to change fuse and operating power switch in protector; Also can concentrated setting in control cabinet.
Referring to Fig. 2, Fig. 3 and Fig. 4, this electric heating part 3 is three, height differs, arranged in a crossed manner on installing plate 1, to guarantee the water of first heating container central part, water temperature raises steadily, makes hydrone to external diffusion, too much with the heat energy of avoiding being scattered and disappeared by container outer wall too soon because of the rising of external container water temperature as far as possible, cause heat energy loss.This is furnished with the water being beneficial in small container and heats.
Referring to Fig. 7, this electric heating part 3 is three, along circumference successively uniform being arranged on installing plate 1, for the water to bulk container, heats, and is convenient to unified processing, can effectively prevent heat energy loss described above simultaneously.
Referring to Fig. 4, the bottom of this installing plate 1 is provided with buoyancy aid 7, is convenient to this electric heater to be directly placed in compared with large heating container the water of container is heated and do not sunk.This buoyancy aid 7 is assemblied in the bottom of installing plate by dismountable structure, be convenient to dismounting, easy to use.
Referring to Fig. 6, this electric heating part also includes controller 4, described power switch 34 is connected with controller 4, this controller 4 is connected with buzzer 6 with temperature inductor 5, this temperature inductor 5 is for detection of the water temperature of institute's heating water, it is arranged on (or concentrated setting is in control cabinet) on installing plate, and this buzzer 6 is reminded user for sounding, and it is arranged on (or concentrated setting is in control cabinet) on buck plate.During use, by temperature inductor, detected the water temperature of heated water and reached controller 4, controller compares with default value after receiving water temperature data, to control buzzer and power switch.As 100 ℃ of the temperature of boiled water, be generally set as 95 ℃, after reaching this temperature, controller is controlled buzzer and is sounded and report to the police to remind user, controls power switch 24 simultaneously, cuts off the electricity supply, and stops water heating.
