Description

The electromagnetic induction heating shower

The utility model is a kind of electromagnetic induction heating shower, belongs to sanitary installation, uses for family's washing and shower.

At present, shower miscellaneous is a lot of on the market, can be divided into two types substantially: a kind of is flow-type, adopt directly and conduct, promptly the heating liberated heat is directly passed to cold water, and cold water is flowed through and become hot water behind the heater, generally be with exposed resistance wire, directly soak in heated cold water,, heat characteristics rapidly though it is little to have thermal inertia, but the electrothermal load amount is big, electric quantity consumption is many, and the electrical power of heating element heater generally will be more than 3 kilowatts, and safety coefficient is low.Another kind is a storage type, must install water tank ability stored hot water additional, generally adopts tubular electrothermal element, can reduce electrical power, improve safety coefficient, but in use be subjected to the restriction of water tank capacity again, and also complex structure, the cost height.In sum, no matter be flow-type or storage type, ubiquity problems such as power consumption is many, and electric conversion efficiency is low, and heating easily punctures, and easily leaks electricity, and water temperature is wayward.

In view of above-mentioned problems of the prior art, the purpose of this utility model is that a kind of little power consumption will be provided, thermal conversion efficiency height, firing rate

Fig. 1 is a general structure schematic diagram of the present utility model

Fig. 2 is a line map of the present utility model.

In the accompanying drawing: the 1st, shell 2 is that sponge 3 is that inner bag 4 is that electromagnetic induction coil 5 is that coil brace 6 is that iron core 7 is that outlet pipe 8 is that inlet opening 9 is that water inlet pipe 10 is that cover plate 11 is that power supply indicator 12 is that power switch K 13 is that capacitor C 14 is that lid 15 is that attaching plug 16 is sealing rings.

As shown in Figure 1 and Figure 2, this shower is by shell, inner bag and electromagnetism Induction heater three parts form.

Shell 1 is a cylinder, and water inlet pipe 9 is arranged at top, so that connect the water source.

Inner bag 3 also is a cylinder, and inlet opening 8 is arranged at the bottom, and cold water orifice flow is thus gone into iron core.

Electromagnetic induction heater: by electromagnetic induction coil 4, coil brace 5 and iron core 6 are formed, and coil 4 has two to be L1 and L2, all on coil brace 5.Iron core 6 is inside spin iron cores, and fin is promptly arranged in iron core, and surfaces externally and internally all scribbles insulating barrier, and iron core 6 is contained in 5 li of coil braces, promptly is heater.Its circuit is to connect like this; 11 groups of resistance R and indicator lamps are fast, not limited by water tank capacity, and electromagnetic induction heating shower safe in utilization.

In order to achieve the above object, the utility model realizes that by following proposal shower has shell, heater, water inlet pipe and outlet pipe, its design feature is: this shower is cylindric, is made up of shell, inner bag and electromagnetic induction heater three parts, and water inlet pipe 9 is arranged at shell 1 top.Inlet opening 8 is arranged at inner bag 3 bottoms.Electromagnetic induction heater is made up of coil 4 and iron core 6, coil on support 5, two termination AC powers of coil, iron core 6 is contained in the support 5.Heater cartridge is 3 li of inner bags, and inner bag 3 is contained in 1 li on shell, between shell 1 and the inner bag 3 sponge 2 is arranged, and outlet pipe 7 is contained in the iron core 6, shell and inner bag, and inner bag all is connected with screw with iron core, and cover plate 10 is arranged at the top, and lid 14 is arranged on the cover plate.

Adopt the shower of said structure to have following advantage: reasonable in design, easy to use, power consumption is few, can not leak electricity, safe and reliable, heating is rapid, and energy loss is little, the thermal conversion efficiency height, not limited by water tank capacity, boiler and complicated pipeline need be installed, not be subject to seasonal restrictions environmentally safe.

Below in conjunction with accompanying drawing the utility model is elaborated into a series arm; Capacitor C and coil L ₁Form a series arm, this branch road and coil L ₂Parallel connection, the two ends of the two ends of coil and resistance and indicator lamp series arm also are connected on the AC power.

Heater cartridge is 3 li of inner bags, inner bag 3 is contained in 1 li on shell, between inner bag 3 and the shell 1 sponge 2 is arranged, outlet pipe 7 is contained in 6 li of the iron cores of heater, outlet pipe 7 adds ○Xing Mifengquan 16 with the shell junction, tightens together with sealing nut, all adds ○Xing Mifengquan 16 between shell and inner bag, inner bag and the iron core, connect with screw, become as a whole.Cover plate 10 is arranged at the top, and lid 14 is arranged on the cover plate, and power switch 12 and power supply indicator 11 are contained on the lid, and capacitor 13 is contained on the cover plate, and the lower end of outlet pipe is connected to flowing water Valve, coiled pipe and shower nozzle.

During use, earlier water inlet pipe 9 is connected the water source, attaching plug 15 is connected power supply, turns on the power switch 12 again, and power supply indicator 11 is luminous, and heater is started working, at this moment alternating current flowing through coil L ₁The branch road of connecting and this branch road and coil L with capacitor C ₂The shunt circuit of forming produces alternating magnetic field in the iron core 6, alternating magnetic field generates eddy current at the iron core internal induction, because eddy current flows in iron core, can cause eddy-current loss, moreover flowing through coil L ₁Current phase lag behind coil L ₂90 ° of current phases also can cause magnetic hystersis loss, and both produce heat-flash jointly, for cold water heating water provides heat energy.Cold water flows in the shell 1 from water inlet pipe 9, process sponge 2 is lentamente in the 8 inflow iron cores 6 of inlet opening, and upwards flow to the top along the inside spin fin, cold water is heating gradually, open the flowing water Valve of outlet pipe lower end, hot water just flows out through outlet pipe, coiled pipe and shower nozzle, this shower little power consumption, heating is fast, and is safe in utilization.
