Abstract

The utility model provides a multi -purpose control by temperature change electric heat pot of photovoltaic direct current. It comprises multi -purpose electric heat pot, the furnace body two parts that generate heat. The furnace body that generates heat is in the furnace body, becomes mosquito -repellent incense pot type to the long tube dish that generates heat, puts on upwards reflect thermal reflection stratum insulating layer, carries high heat generation pipe efficiency and the interior device of protection furnace body, installs direct current contactor in the furnace body, and temperature controller, supply socket are with the stove foot fixed furnace body. Multi -purpose electric heat pot comprises the pot that is greater than the furnace body, the bowl that is less than the pot external diameter, food steamer, loads onto pot ear, handle and food steamer ear on their both sides, and the food steamer is covered to load onto and is dripped the son, is convenient for take and puts. The multi -purpose control by temperature change electric heat pot of this kind with photovoltaic power generation's direct current, energy -concerving and environment -protective low carbon, with the break -make that the direct current operational relay comes control to generate heat and coil, can not draw the arc. Pot, bowl, food steamer are multi -purpose, can make up automatic temperature adjustment, convenience wantonly. Be fit for directly unit and family's use with formula photovoltaic power generation.

Description

The multiplex temp .-control electric pot of photovoltaic DC

Technical field

The utility model relates to a kind of cooker, especially uses the temp .-control electric pot of photovoltaic direct current supply.

Background technology

At present, known electric food warmer is all use 220V AC-powered, does not have a kind of electric food warmer to be that photovoltaic DC is powered.In order to energy-conserving and environment-protective, units concerned are my patent of step popularization then now, family's dual track system power supply need not, few with, directly use system (ZL201220245052.1), now referred to as " directly using formula photovoltaic generation ", DC voltage 220V, during high-power electric appliance powered by direct current, arcing is wanted when switch opens and power cutoff, electrical equipment cannot be used, because temperature controller and heat-generating disc are series connection, cause temperature controller contact to be blown and adhesion.

Summary of the invention

During in order to solve electric food warmer photovoltaic powered by direct current, want arcing when temperature controller is opened and close power supply, cause temperature controller contact to be blown and adhesion, cause the problem that temp .-control electric pot cannot use, the utility model provides a kind of temp .-control electric pot of photovoltaic direct current supply, inhibits arcing.

The utility model solves the technical scheme that its technical problem adopts: it is made up of multiplex electric food warmer, heating body of heater two parts.Heating body of heater becomes mosquito-repellent incense pot type in body of heater, heating long tube dish; above the reflecting layer thermal insulation layer being placed on upwards reflecting heat, improve device in heat-generating pipe efficiency and protection body of heater, in body of heater, D.C. contactor is installed; temperature controller, supply socket, fix body of heater with stove pin.Multiplex electric food warmer, is made up of the pot be placed on body of heater, bowl, food steamer, and bowl food steamer external diameter is equally large, steam box bottom one step can be fixed on bowl, and external diameter is less than pot, loads onto pot handle, handle and food steamer ear on their both sides, steamer cover is loaded onto and drips son, be convenient to taking and placing.Temperature control principle is as follows: when the temperature of temperature controller sensing is lower than design temperature, D.C. contactor is connected, contacts of contactor A and B, C and D connect, mosquito-repellent incense heat-generating pipe obtains electric work, when temperature controller arrives design temperature, D.C. contactor discharges, and its contact A and B, C and D disconnect, and mosquito-repellent incense pot type heat-generating pipe does not work.

The beneficial effects of the utility model are, use the direct current of photovoltaic generation, energy-conserving and environment-protective low-carbon (LC), controls the break-make of heat-generating pipe with DC operation relay, can not arcing, and pot, bowl, food steamer are multiplex, can be combined, automatic temperature-control, convenience.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated.

The multiplex temp .-control electric pot structure chart of Fig. 1.

Fig. 2 mosquito-repellent incense heat-generating pipe, reflecting layer insulating layer structure figure.

Fig. 3 temperature control circuit schematic diagram.

In figure 1, body of heater 2, stove pin 3, temperature controller 4, indicator lamp 5, supply socket 6, D.C. contactor 7, reflecting layer 8, mosquito-repellent incense pot type heat-generating pipe 9, pot 10, bowl 11, handle 12, food steamer 13, food steamer ear 14, lid 15, drip son 16, thermal insulation layer 17, pot ear.

Detailed description of the invention

Fix at body of heater (1) bottom stove pin (2) in FIG, the front temperature controller (3) of stove, indicator lamp (4) supply socket (5), loading onto D.C. contactor (6) thermal insulation layer (16) reflecting layer (7) in stove above it is mosquito-repellent incense pot shape heat-generating pipe (8), be pot (9) above mosquito-repellent incense pot type heat-generating pipe (8), pot ear (17) bowl (10) handle (11), food steamer (12) food steamer ear (13) lid (14) drip son (15).In fig. 2, reflecting layer (7) be above mosquito-repellent incense pot type heat-generating pipe (8) be thermal insulation layer (16) below it.

In figure 3, positive source, connect temperature controller (3) contacts (6) coil with direct current and get back to negative pole, when DC operation relay (6) energising work, under relay is inhaled, A and B, C and D conducting, mosquito-repellent incense pot type heat-generating pipe (8) works, and indicator lamp (4) is bright.When temperature controller (3) arrives design temperature, disconnect DC operation relay (6) coil power, contact tripping, deenergization, indicator lamp goes out.
