Description

The multiplex electric food warmer of AC/DC temperature control
Technical field
The present invention relates to a kind of cooker, especially with the temp .-control electric pot of AC/DC.
Background technology
At present, known electric food warmer all uses 220V AC-powered, it does not have a kind of electric food warmer is that AC/DC is powered. in order to energy-conserving and environment-protective, units concerned now progressively promote my patent, family's doubletracks system power supply need not, few use, straight system (ZL201220245052.1), now it is called for short " directly using formula photovoltaic generation ", volts DS 220V, high-power household electrical appliance, when using powered by direct current, arcing is wanted when switch is opened and breaks, switch contact is caused to blow or adhesion, I solves arcing problem with the DC operation rly. of 220V, effect is fine, and applied for patent, (ZL201520607376.9), but when directly by formula photovoltaic generation electric power deficiency, need by AC-powered, when multiplex for direct current temperature control electric food warmer attaching plug is inserted into 220V alternating-current, when sensor is connected, find the magnetic deficiency of DC operation rly. because producing, under the contact of rly. is not inhaled, can not work, the alternating-current relay afterwards the DC operation rly. being contained in electric food warmer being used instead 220V is tested, find that result of use is also fine in alternating-current, also protect the contact of sensor, 220V direct current is tested and can work, but less than five minutes, alternating-current relay just coil burn out, development solves multiplex electric food warmer AC/DC with how facilitating, very urgent.
Summary of the invention
When using in 220V alternating-current to solve the DC operation rly. of 220V, because producing the main problem that magnetic deficiency can not work and 220V alternating-current relay to be burnt out in 220V direct current, the present invention provides one to not be used in any manual switch on the multiplex electric food warmer of temperature control, power plug wire is directly inserted in alternating-current or galvanic supply socket, it is achieved that AC/DC.
The technical solution adopted for the present invention to solve the technical problems is: it is made up of multiplex electric food warmer, temp controlled heating stove two portions. Multiplex electric food warmer, is made up of the pot being placed on body of heater, bowl, food steamer, and bowl food steamer external diameter is equally big, steam box bottom can be fixed on bowl with a step, external diameter is less than pot, loads onto pot ear, handle and food steamer ear on their both sides, steamer cover is loaded onto a son and is convenient to taking and placing.Temp controlled heating stove is in body of heater, the long pipe dish of heating is become mosquito-repellent incense type, it is placed on above the reflecting layer thermofin of upwards reflecting heat, improve device in heat-generating pipe efficiency and protection body of heater, DC operation rly. is installed, temperature controller, pilot lamp, supply socket, between temperature controller and DC operation rly., a bridge rectifier that adds one, need not change, solve AC/DC problem easily, in order to the noise suppressing DC operation rly. to produce when alternating-current uses, add line filter circuit, the two is combined composition filter rectification device, two wires of temperature controller, a positive pole connecing filter rectification device and exporting, another root connects one end of DC operation relay1 coil, the other end of DC operation relay1 coil, connect the negative pole of filter rectification device, the electrode of electric heating cooker plug socket, except supply filter rectifier, also it is electrically connected the AB of DC operation rly., DE two is to the half AD contact of contact, second half BE contact electrical connection heat-generating pipe, the break-make of DC operation relay1 coil is controlled with temperature controller, thus control the break-make of heat-generating pipe, because of DC operation rly., quick action, contact stroke is big, open when being again positive and negative electrodes in same or turn off, not arcing in direct current uses. its principle of work process is as follows: when an alternating current is used, alternating-current exports through filter rectification device, the coil of electrical connection sensor and DC operation rly., thus controls the contact of DC operation rly., DC operation makes the contact of rly., half sending and receiving heat pipe, second half electric connection of power supply inlet wire, reduces filter rectification device load and loss, heat directly to heat-generating pipe with alternating-current, when arriving the temperature of setting, temperature controller disconnects, and does not reheat. when in-furnace temperature is lower than lower valve value, connecting again DC operation and make rly., heat-generating pipe is electricity continuation heating again. when using powered by direct current, direct current is directly by filter rectification device, and loss is very little, other principles and the same alternating-current of process. here illustrate a bit, filter capacitor must not be increased after bridge rectifier, otherwise when alternating-current uses, volts DS is no longer 220V, rise to immediately and lie prostrate 300 more, very soon burn out DC operation rly..
The invention has the beneficial effects as follows, this kind of multiplex electric food warmer, adopt filter rectification device, not be used on electric food warmer and do any operation, it is achieved AC/DC, not arcing. Pot, bowl, food steamer are multiplex, can arbitrary combination, automatic temperature-control, convenience.
