Abstract
The utility model relates to a spiral resistance wire quick miniature water-heater, which is in daily use. The utility model comprises a casing, a nozzle, a core body, a central water inlet pipe, a return hood, and a resistance wire seat. The internal parts of annular chambers between the external circle of the resistance wire seat and the internal circle of the casing are provided with a naked spiral type resistance wire which is externally connected with a power supply through lead-out leading wires. The naked resistance wire of the utility model can directly heat to refluxing tap water; heating is rapid; heat efficiency is high, and usage is safe, reliable, and convenient.
Description
The utility model relates to a kind of quick miniature hot-water device of electric heater used in everyday, particularly a kind of spiral resistance wire.
In the prior art, the micro-electric heating hydrophone of armouring heating wire is arranged, because of its resistance wire through armouring, need to increase its volume cavity, and heating is slowed down and reduce the thermal efficiency.
The purpose of this utility model is to provide a kind of spiral resistance wire quick miniature hot-water device.It can improve firing rate, and has the higher thermal efficiency.
In order to achieve the above object, the utility model adopts following technical scheme: the same housing, shower nozzle, core body, center water inlet pipe, backflow cover and the resistance wire seat of including with prior art of the utility model.It is characterized in that settling in the annular chamber between the circle in resistance wire seat cylindrical and the housing the spiral resistance wire of nude, resistance wire is by drawing the lead external power supply.During use, the running water of the backflow in water heater is flowed through bare resistance wire and directly is heated, and heat exchange effect is good, and heating is rapid, thermal efficiency height.
The utility model can be equipped with the current electric switch in the water inlet of center water inlet pipe, an external again relay and switch.During use, current make resistance wire connect power supply through the current electric switch; Cut off the water supply when stopping using, then the current electric switch is cut off the electricity supply, and makes water heater not charged, guarantees safe in utilization.
Housing of the present utility model can be designed to connect a handle body, can be used for connecting flexible pipe and hand-held shower.Housing, core body, backflow cover and resistance wire seat etc. all adopt the engineering plastics injection mo(u)lding of electric insulation.
The utility model has following conspicuous advantage compared with the prior art: the utility model adopts the directly running water heating to refluxing of bare resistance wire, and heating is rapid, thermal efficiency height; Water inlet is equipped with the current electric switch, and is safe, easy to use.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the circuit theory diagrams of Fig. 1 example.
An optimum implementation of the present utility model is: referring to Fig. 1 and Fig. 2, the quick miniature hot-water device of this spiral resistance wire includes housing 1, shower nozzle 10, core body 4, center water inlet pipe 6, cover 7 and resistance wire seat 8 reflux, settle the spiral resistance wire 9 of nude in the annular chamber in resistance wire seat 8 cylindricals and the housing 1 between the circle, resistance wire 9 is by drawing lead 3 external power supplys.Current electric switch 5 is equipped with in the water inlet of center water inlet pipe 6.Current electric switch 5 is hard-wired two sheet metals 11,12 of spaced and parallel, and wherein a slice sheet metal 12 has central through hole, and another sheet sheet metal 11 has the through hole of decentered distribution, constitutes the current loop.When current were arranged, two sheet metals electricity was connected, during no current then TURP break.Referring to Fig. 2, drawing an external relay J and K switch on the lead 3 of connecting power supply, its circuit structure is: one tunnel a slice sheet metal 12 of AC power live wire 13 through K switch and relay coil J connection current electric switch 5, and an end of spiral resistance wire 9 is connected on live wire 13 another roads through relay contact JK; A road of AC power zero line 14 is connected another sheet sheet metal 11 of current electric switch 5, and the other end of spiral resistance wire 9 is connected on another road.Housing 1 connects a handle body 2.Housing 1, core body 4, reflux cover 7, resistance wire seat 8, shower nozzle 10 and handle body 2 are by the engineering plastics injection mo(u)lding.When bringing into use, first Closing Switch K, the tap of fetching boiling water again makes water heater connect water source from the beginning, the running water current electric switch 5 of flowing through earlier, then relay coil J energising and make its contact JK closure, resistance wire 9 energising heating; Current flow into the annular chamber that resistance wire 9 is installed from center water inlet pipe 6 lower ends, flow into the cover 7 that refluxes again from annular chamber top, flow into shower nozzle 10 back ejections by cover 7 lower ends of refluxing.Like this, current are through whole resistance wire 9 and by directly effectively heating.Cut off the water supply when stopping using, relay coil J outage, then its contact JK opens and cuts off the resistance wire power supply.
