When system brought into operation, this moment, boiler was interior anhydrous.Upper and lower temperature controller is serially connected with in the water pump circuit, and this temperature controller is the type of automatically replying, and its contact is a normally opened contact.Near the following electrothermal tube 2-1 boiler tube wall is by dry combustion method, conduct heat and the rapid heat conduction of following thermal sensitive piece 3-1 by boiler tube wall, after making down the temperature of thermal sensitive piece rise to down temperature controller 3-2 to set the take-off temperature, the contact by often open transfer to normally closed, connect the power supply of water pump 3-11, water descends temperature by in the water pump 3-11 suction boiler.Water level in the boiler rises after the water filling, make down near the tube wall temperature of electrothermal tube 2-1 begin to descend, temperature is by the rapid conduction of boiler tube wall and following thermal sensitive piece 3-1, when temperature drops to the recovery temperature of temperature controller 3-2 setting, the contact was opened by normally closed often transferring to, cut off pump power, water pump stops to draw water in water tank.
The length that adds the water time depends on take-off temperature and the recovery temperature that upper and lower temperature controller is set.
Drain plug 1-5 is installed on the drain connection 1-4, can back out drain plug when the needs boiler rinsing or when discharging in the boiler remaining water.
The water storage situation of control circuit board 5-2 monitoring water tank 3-11.Can realize anhydrous warning and realize other control functions by modes such as light, sound.
Operation principle:
When use for the first time or boiler rinsing after, anhydrous in this moment boiler.Press power switch 5-1, therefore do not have enough steam pressures, the pressure that this moment, the boiler internal pressure set less than pressure switch 4-4 because of there being water in the boiler.Pressure switch is in and the electrothermal tube on-state.Upper and lower electrothermal tube is connected power supply.Because anhydrous in the boiler, electrothermal tube heating this moment produces heat makes the boiler tube wall dry combustion method.Following electrothermal tube 2-1 is bigger because of power, the heat that produces is bigger, near its boiler tube wall heats up faster than near the tube wall last electrothermal tube 2-2, the heat that following electrothermal tube 2-1 produces passes through down, and thermal sensitive piece 3-1 conducts temperature to the temperature-sensitive face of following temperature controller 3-2, under the acting in conjunction of tube wall heat conduction and following thermal sensitive piece conduction temperature, when following thermal sensitive piece 3-1 temperature rises to down the take-off temperature that temperature controller 3-2 sets rapidly, this temperature controller contact by often open transfer to normally closed, thereby make water pump connect power supply.Water pump draws water from water tank, by water inlet system water is injected in the boiler.
Water level is risen, because the good heat conductivity of metal, the temperature of following thermal sensitive piece 3-1 begins to descend.When dropping to the recovery temperature of electric heating temperature control device 3-2, the contact is cut pump power by the normally closed normally open that turns to again thereby break, and stops to add water.Electrothermal tube 2-1 switches on always down in adding the water process, and the water in the boiler is transformed into water vapour owing to absorbing heat.
Do not reach the water level that electrothermal tube 2-2 will control owing to the water yield that adds for the first time is less, at this moment, last electrothermal tube produces heat always after energising, near its boiler side walls temperature is also rising gradually, and a heat part that goes up electrothermal tube generation itself simultaneously is transmitted to the temperature-sensitive face of temperature controller 3-5 by last thermal sensitive piece 3-4.When temperature rises to certain value, when being enough to reach the take-off temperature that temperature controller 3-5 sets, the contact transfers normally off to by normally open, thereby makes water pump connect power supply.Water is injected in the boiler.Because water constantly injects in the boiler, make water level begin to rise, near the boiler side walls temperature the last electrothermal tube begins to descend.Drop to when going up the recovery temperature that electric heating temperature controller 3-5 sets up to the temperature of last thermal sensitive piece, the contact of last temperature controller just transfers normally open to by normally off, cuts off the power supply of water pump this moment, and water stops injection.Finish the water filling first time of system's operation.
Be converted into water vapour along with water absorbs heat energy, water level descends gradually, and near the tube wall the upper and lower electrothermal tube is by dry combustion method, and upper and lower thermal sensitive piece temperature raises rapidly.By last temperature controller 3-5 and following temperature controller 3-2 parallel connection, when wherein any temperature controller temperature arrived the preset action temperature, this temperature controller contact was by transferring normally off to from often opening, thus the connection pump power.Water pump draws water from water tank and injects in the boiler, and along with the injection of water, water level in the boiler begins to rise, along with the rising of water level, tube wall temperature begins to descend, when temperature drops to the numerical value that sets, its temperature controller transfers normally open again to by normally off, cuts off pump power at this point, and water stops to inject.So circulation is gone down.Only quit work up to system.
(otherwise often reach normally closed or) that temperature controller is provided with makes the temperature of contact conversion, answers steam sufficient and stable in the As soon as possible Promising Policy boiler and constant compression force as far as possible, for this reason, water level in the boiler remained within a certain height.Each water injection rate can not be too big.Constant as far as possible to guarantee steam and pressure.
Following electrothermal tube 2-1 is mainly used to produce high temperature continuously.Automatically added in the process of water by temperature controller control water pump above-mentioned, electrothermal tube constantly produces heat, and a heat part is used for heating boiler body 1, and a part is directly conducted to temperature controller by upper and lower thermal sensitive piece, and then realizes the automatic control of moisturizing.After boiler body reached a kind of thermal balance, its most of heat was used for the water in the heating boiler, makes water be converted into water vapour.Along with the generation of steam, the boiler internal pressure increases, after pressure increases to pressure switch 4-4 capping, pressure switch contact NC and NB disconnect, contact NC and NA connect (referring to Fig. 3), thereby upper and lower two electrothermal tubes and general supply are disconnected, and electrothermal tube stops heating.Connected indicator lamp 5-4 simultaneously, by light, acoustic alarm.Because after upper and lower electrothermal tube and power supply disconnected, electrothermal tube no longer produced heat, near the temperature its boiler wall descends gradually, and quantity of steam reduces naturally.If disconnecting the long water that makes of the time of electrothermal tube can't continue to heat, this moment, the boiler internal pressure descended, and after pressure dropped to certain value, pressure switch 4-4 contact NC and NA disconnected, contact NC and NB reclose, and upper and lower electrothermal tube has disconnected indicator lamp 5-4 power supply again with power connection the time.Electrothermal tube energising back is continued heating and is produced steam.Circulation so repeatedly is in the safe range that pressure is controlled at set.The steam that ensures hand device ejections such as flatiron or shower nozzle simultaneously has certain pressure.
When pressure switch 4-4 damaged, pressure switch can't be finished the translation function of contact, at this moment, when the boiler internal pressure has reached the limiting value that safety valve 4-2 sets, the safety valve tripping, increased pressure is just discharged from the safety valve outlet.
Control pressurer system and temperature controller control water pump add water automatically to carry out simultaneously.When not pressing microswitch 5-3 for a long time, (do not consume steam), sealing fully in the boiler tube.Because electrothermal tube 2-1 power is bigger down, the water in the continuous heating boiler, steam constantly produces, steam pressure constantly increases, and along with the generation of steam, water level is also descending, when water level drops to when going up the water level that electrothermal tube 2-2 will control, last temperature controller is controlled the water pump water adding.Water filling a moment, the last temperature controller power supply that switches off the pump stops water filling.And the water that injects constantly is heated the generation steam, and water level begins again to descend, and when water level drops to when going up the water level that electrothermal tube will control once more, connects pump power as previously mentioned, begins to add water again.Circulation 2-3 all after dates like this, the steam pressure in the boiler is enough big, and pressure switch and safety valve play duplicate protection, make automatic water-adding system misoperation can not take place, and promptly refer to water filling when should not adding water.
In the utility model most preferred embodiment, boiler body adopts stainless pipe, tube wall external diameter 50mm.
The pressure switch that the utility model uses be adopt public use already on the market, be exclusively used in pressure switch general on the steam generating ironing machine.The made from aluminium profile that thermal sensitive piece adopts good heat conductivity and has certain pliability.Temperature controller adopts the ceramic material of stable performance.
In order to adapt to the needs that beautify family and office space, the utility model profile packing can be made exquisiteness and unique all kinds of moulding.Making it the utility model promptly is industrial products, does not also lose to have and beautifies and decorative effect.
The foregoing description is only for the usefulness that the utility model is described; and be not to be to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model, other variations done and the technical scheme that all are equal to also should belong to the category of the utility model protection.
