Description

Quick eddy current water heater

The utility model relates to water heater, particularly relates to the heater technology of electric heater.

Existing water heater by its heat supply energy difference, can be divided into gas heater and electric heater.The major defect of gas heater is generally to need liquefied gas as fuel, the carrying trouble, and especially skyscraper must be paid able-bodied labour, and contaminated environment, uses dangerous; Existing electric heater is to adopt dissimilar electrothermal tubes or electrical bar etc., and its major defect is the thermal efficiency low (utilization rate of electrical is about 46%), and same security is relatively poor, and casualty accident appears in serious meeting.

The purpose of this utility model is to adopt different materials, utilizes the material difference and the resistance difference, produces the eddy current heat by the heating board induction, water to overcurrent heats, and firing rate is fast, thermal efficiency height, flow is big, eddy current water heater safe in utilization, reliably quick.

The technical scheme of the quick eddy current water heater of the utility model is: the water heater housing is arranged, heater and water pipe etc. are formed, its so-called heater be as a winding step-down transformation coil, iron core and as the sliver of Secondary Winding, the coil joining power, sliver connects the eddy-current heating plate, and the heating water channel is arranged in the heating board.

Quick eddy current water heater of the present utility model has insulating barrier between sliver and a winding, between eddy-current heating plate and a winding thermal insulation layer is arranged.

Quick eddy current water heater of the present utility model, its so-called sliver are optimum electric conductor red copper bars.

Quick eddy current water heater of the present utility model, its so-called eddy-current heating plate is that cast iron is made.

Heating water channel in the quick eddy current water heater of the present utility model, its eddy-current heating plate is the shaped form water channel, and heating is abundant, and watercourse port taps into water pipe or outlet pipe.

Quick eddy current water heater of the present utility model, adopt specific transformer type,, the water in the eddy-current heating plate is heated by the different eddy current heats that produce of the resistance of sliver, heating board, compared with the prior art, have heating rapidly, thermal efficiency height (reaching more than 85%), discharge is big, but amount of heat regulated at will, volume little (not having water tank), long service life, characteristics such as safe and reliable.

Fig. 1 is the quick eddy current water heater organigram of the utility model;

Fig. 2 is that the quick eddy current water heater A of the utility model is to sectional view;

Fig. 3 is a heating water channel schematic diagram in the quick eddy current water heater heating board of the utility model;

Fig. 4 is the quick eddy current water heater circuit of a utility model schematic diagram.

Below in conjunction with Fig. 1-Fig. 4 an embodiment of the present utility model is elaborated.

1, housing; 2, support; 3, insulating barrier; 4, coil; 5, sliver; 6, switch; 7, support; 8, water inlet pipe; 9, thermal insulation layer; 10, eddy-current heating plate; 11, heating water channel; 12, outlet pipe; 13, indicator lamp; 14, electrical network is isolated (step-down); 15, electrical network is isolated (heating); 16, sliver and heating plate joint.

The utility model relates to a kind of quick eddy current electric heater, so that heating, heater to be installed in the housing 1.Concrete structure is the line bag that coil 4, iron core composition are installed on support 2,7, can be considered winding one time, and power supply is played transformation (step-down) effect, online bag is installed sliver 5 outward, sliver is good electric conductor, generally selects red copper bar etc., can be used as Secondary Winding, between sliver and the line bag insulating barrier 3 is arranged, sliver connects eddy-current heating plate 10, and heating board is made with cast iron, and resistance is big, and sliver resistance is very little, so produce inductive loop.Voltage is very low on the sliver, adding that the bag of reaching the standard grade is outer to have electrical network 14,15 to isolate, and is safe in utilization, cast iron heating board resistance is very big, so be eddy-current heating plate 10, heating water channel 11 is arranged in the eddy-current heating plate, and the water of water inlet pipe 8 heats water channel to outlet pipe 12 through shaped form, can be without water storage tank.For the heat that makes heating board does not influence the line bag, thermal insulation layer 9 can be installed.Entire circuit has switch-box 6, beacon lamp 13.
