Description
Technical field
The present invention relates to " a kind of solid-state contactless long-life electric kettles ".Be for family boil water field, its
Advantage is that service life is several times longer than common insulating pot.
Background technology
In everyday home life, it is most usual thing that people, which have tea and boil water, from initial baked wheaten cake kettle to electrothermal tube
Water small pot with a handle and a spout for boiling water or herbal medicine, developing deeply to current Portable kettle are regenerated by constantly updating, and existing Portable kettle is strictly best
, it not only heats up water express also light handy, but also have disadvantage, ropy to be just broken with three or four months, high-quality is most
With being also broken less than 2 years, from the point of view of the insulating pot situation repaired for colleague and family through me, main problem goes out in temperature control bullet
On piece and energization contact switch, because the power of insulating pot is usually in 1800W or so, electric current is 8 amperes or more, each time
Can all occur high temperature electric spark in galvanization on contact switch, electric spark will appear two kinds of accidents, and one, contact burnt production
Sheng Jue Vela no powers；Two, the high temperature generated can allow the plastics of surrounding to burn deformation and cause malfunctioning switch.Present maintenance cost
Very high, accessory is not also complete, send and repaiies the time and also grow, I is the technical staff for doing electronic engineering, finds many to scrap kettle liner
All be 304 food-grade stainless steels, main part electrothermal tube neither one be it is bad, appearance it is very new be all because small part damage becomes
Scrap is too unfortunate.

Be scheduled in the heat dissipation aluminium dish (9) in bottom of the pot seat (5), be inserted into the recessed deck (11) of connection electricity connection projection seat (7-2) afterwards, connect electric contact
(11-1) with connect circuit in projection seat be connected, temperature detect switch (TDS) (11-2) be mounted on connect on the recessed deck (11) of electricity, the aluminium cap of switch
It is in direct contact with aluminium backing (2-1).
Circuit part forms temperature measurement circuit, resistance R3, R4, R5, triode Q2, light by resistance R1, RT, R2, triode Q1
Coupling U forms latching circuit, and capacitance C1, C2, C3, inductance L form L.C filter circuits, integrated circuit TL431, resistance R8, R9, electricity
Hold C4 and form regulator circuit, diode D1, D2, capacitance C5, resistance R10 form step-down rectifying circuit, resistance R6, bidirectional triode thyristor
G, heating tube EH, red flashing light pipe LED, resistance R11 compositions power drive, fever, display circuit, fuse FU, touching switch
S, resistance R7, the security protection of temperature detect switch (TDS) EK compositions, start-up circuit.
Operation principle is：About 80% water is added in pot liner 2, presses pot lid 3 with hand and is laid flat for mechanical part,
The cervical rotation connector 3-2 of pot lid is rotated by 90 ° on rotary shaft 3-3, at this moment stuck point 3-5 to be to go on the 4-6 of card face, by
It uncaps the support of holder 4, pot lid is closed, then kettle body is put on power supply base 7, presses and starts key 6 in it
The LED light in portion, which shines, illustrates way circuit to connect, and electrothermal tube 2-2 fevers are heated up water, (note：It is not to start key 6 and start key with existing pot
Equally, existing pot is pressed down to be sucked to water to have opened and just be unclamped, and one pine of this startings key pressing hand that gone lamp bright falls down again but lamp
Still bright, because there is a triggering latching circuit in inside) when water temperature slowly rises to 98 degree, signal is passed to control electricity by sensor 8
Road, control circuit, which is started to work, cuts off general supply, end of heating up water.Next lid-opening button 4-1 is pressed with hand thumb, branch of uncapping
In the pressure lower bracket axis 4-4 of button, revotating card face 4-6 is detached from stuck point 3-5, effect of the pot lid 3 in torsional spring 3-4 to frame 4 to the right
Rotate up opening automatically down, holder 4 of uncapping is restored to original state under the elastic force rebound for the spring 4-2 that uncaps, entire to work
Flow terminates.Circuit part, principle are：220V AC powers firewire is connected to temperature controller EK and resistance R11 by fuse FU
And optocoupler U, because bidirectional triode thyristor G A1, A2 under no driving power are obstructed can not form back in cut-off state power circuit
The entire circuit in road does not work, and when human hand presses touching switch S, alternating current is on one side by touching switch S in capacitance C5, resistance
It is carried out on R10 after decompression is released by exporting about 30 volts or so of direct current after diode D1, D2, rectification, then passes through integrated electricity
Become 12V DC electricity after road TL431, resistance R8, R9, the partial pressure of capacitance C4, voltage stabilizing, passes through the filter of capacitance C1, C2, C3, inductance L
Become the entire circuit of pure direct current power supply after wave, triode Q2 is connected after obtaining coming the branch pressure voltage of self-resistance R3, R4, light
Coupling U it is primary it is electric after shine, internal controlled silicon conducting after secondary light, alternating current is at this time by controllable inside optocoupler
The through capacitance C5 of silicon, resistance R7, resistance R10 substitute touching switch S, A1, A2 conducting, the heating of the silicon-controlled G of power driving circuit
Pipe EH electrified regulations, LED light shine after resistance R11 current limlitings makees the instruction that is powered, the thermistor RT when water temperature heating is to 98 degree
Resistance value, which becomes smaller, allows the base voltage of triode Q1 to increase, and at conducting state, the base voltage for sponging triode Q2 is kept it turned off,
Optocoupler U ends entire circuit because of dead electricity and disconnects closing, and temperature detect switch (TDS) EK plays safety effects, and logical state is kept in 150 degree,
It is disconnected automatically when circuit breaks down, temperature is higher than 150 degree.
The effect of critical component：Circuit control box (10) is fixed on heat dissipation aluminium dish (9) above, the power device in circuit
Silicon-controlled G, BTA30 when being powered on generated hot temperature be that cooling to put is released by the aluminium dish (9) that radiates.
The beneficial effects of the invention are as follows：One, the extremely simple convenience of method of pot lid 3 is opened by lid-opening button 4-1 using hand,
By boiling hot danger of burning when human hand being avoided directly to uncap.It strikes sparks when two, being powered using contactless solid-state and solve energization in power circuit
Caused parts damages and the key core technology for reducing product service life so that life of product increases considerably.Both facilitated
Consumer reduces the duplication of production of product again, and design advantage advantage as above is obvious.
