Description

Temperature Control Type intelligence is used electric cooker more

The utility model relates to a kind of family expenses electric cooker, and particularly a kind of frame for movement type intelligence with plesichronous and temperature control heating function at intermittence is used electric cooker more.

In the prior art, electric cooker mainly contains two major types, and a class is popular and timing type electric cooker, and another kind of is computer control electric cooker, the former is cheap, universal wide, but function is simple, can not satisfy people's instructions for use, the latter is multiple functional, easy to use, but involve great expense, be difficult to popularize.

The purpose of this utility model is to use electric cooker for the shortcoming that overcomes above-mentioned prior art provides a kind of improved Temperature Control Type intelligence more, multi-functional selection, preset electric cooker cut-in time and boil the time, the analogue computer fuzzy logic control, the realization automation of cooking, cook congee, stew, the convenient use.

The purpose of this utility model can realize by following measure: this electric cooker is based on common electric cooker, set up the plesichronous circuit, temperature control timing control circuit and temperature control intermittent oscillation circuit, the temperature control timing control circuit is composed in parallel by two thermoswitches, the temperature control intermittent oscillation circuit is formed in parallel by thermoswitch and pause switch, the plesichronous circuit is provided with and regularly plays pot switch and the switch that regularly boils, the straight-through contact that regularly plays pot switch connects the switch that regularly boils, timing contact connects the temperature control timing control circuit, the straight-through contact of switch of regularly boiling connects heat-generating pipe, the timing contact of switch of regularly boiling connects the temperature control intermittent oscillation circuit, the temperature control intermittent oscillation circuit is connected with heat-generating pipe, heat-generating pipe and temperature limiter, warmer connects; Another timing contact connects the temperature control timing control circuit, and the temperature control timing control circuit connects timing motor.When regularly playing pot switch connection timing contact, send electricity to give regularly motor through the temperature control timing control circuit, be timed to a little, timing contact disconnects, and connects straight-through contact and begins to send electrical heating; The time switch that boils is connected when leading directly to point to cooking shelves, electric current flows directly into heat-generating pipe and gives the heating of pot courage, when the time switch that boils is connected two timing contacts, electric current send heat-generating pipe by a timing contact through the temperature control intermittent oscillation circuit, as about 97 ℃ of pot courage Nei Wenduda, the thermoswitch of temperature control intermittent oscillation circuit disconnects, electric current send heat-generating pipe through pause switch, carry out the heating at intermittence, electric current send timing motor by another timing contact through the temperature control timing control circuit simultaneously, and a thermoswitch of temperature control timing control circuit is the normal temperature closure, heat up and more disconnect, another thermoswitch is that normal temperature disconnects, and is warmed up to closure about 97 ℃, so heat-generating pipe heats up, the temperature control timing control circuit is obstructed, timing motor stops, and when pot courage temperature was raised to 97 ℃ of left and right sides, temperature control timing control circuit one thermoswitch was connected, timing motor moves once more, up to presetting the time of boiling to point, timing contact disconnects, and finishes the process of boiling automatically.

Concrete structure of the present utility model and embodiment are provided by the following drawings:

Fig. 1 is the circuit structure diagram that Temperature Control Type intelligence is used electric cooker more.

The utility model is described in further detail below with reference to accompanying drawing: the basic composition of electric cooker has pot body, pot courage, pot lid, heat-generating disc, plesichronous circuit, temperature control timing control circuit, temperature control intermittent oscillation circuit, automatic temperature control circuit, with reference to Fig. 1, the plesichronous circuit is provided with two time switch K ₁, K ₂, one has been pot time switch K ₁, another is the time switch K that boils ₂, preferably adopt a dual timer, also can adopt two single timers to connect to form; The temperature control timing control circuit is by thermoswitch K ₅, K ₆Compose in parallel K ₅Be normally closed thermoswitch, after temperature is higher than 50 ℃, K ₅Be off state, K ₅The contact heating dish is installed is carried out the temperature sampling, after electric cooker heating power dish is warmed up to 50 ℃, K ₅Open circuit thermoswitch K ₆Be often to drive thermoswitch, after temperature reaches 98 ℃, K ₆Connect K ₆Be installed in pot body in to, can contact pot courage; The temperature control intermittent oscillation circuit is by thermoswitch K ₄With pause switch K ₃Compose in parallel, thermoswitch is normally closed thermoswitch, after temperature reaches 98 ℃, and K ₄Open circuit K ₄Be installed in pot body in to, can contact pot courage, pause switch K ₃After the energising, repeat to do intermittent conduction; Play pot time switch K ₁Straight-through contact A ₁Connect the time switch K that boils ₂, K ₁Timing contact A ₂With K ₂Timing contact C ₂, thermoswitch K ₅, K ₆Connect, timing motor M connects K ₅, K ₆, K ₂Another timing contact C ₁Connect thermoswitch K ₄, pause switch K ₃, K ₃, K ₄Again with heat-generating pipe R and K ₂Straight-through contact B ₁Connect temperature limiter K ₈With warmer K ₇Back in parallel connects heat-generating pipe R.

In the application, K ₁Connect straight-through some A ₁, K ₂Connect straight-through some B ₁, temperature limiter K ₈Connecting, promptly is the shelves of cooking, and electric current is through K ₁, K ₂Supply with heat-generating pipe R, heating pot courage, after meal was cooked, temperature limiter was jumped the insulation of pulling automatically; Regularly play pot as need, can be K ₁Be preset to institute and fix time, electric current is through A ₂, normally closed thermoswitch K ₅Power supply motivation M running is timed to some A ₂Disconnect, connect A ₁Play pot.Work as K ₂Connect timing contact C ₁, C ₂, the shelves of promptly cooking congee, electric current is through normally closed thermoswitch K ₄Flow into heat-generating pipe R and give the heating of pot courage, when reaching 98 ℃ in pot, K ₄Automatic disconnection, electric current flows into heat-generating pipe through pause switch, and pot courage is carried out the intermittence heating; Normally closed thermoswitch K of while ₅Probe temperature reaches 50 ℃, K ₅Automatic disconnection, time motor M is out of service, when temperature reaches 98 ℃ in pot, often opens thermoswitch K ₆Automatically connect, motor M turns round once more, up to preset time, and K ₂Disconnect C ₁, C ₂, boil and finish automatically.

Intermittently heating technique of plesichronous, temperature control timing, temperature control has been adopted in the design of this practical full mold, major tuneup the function of common electric cooker, the soup automation is cooked, cooks congee, is boiled in realization, has analogue computer fuzzy logic control function, the reliability height of automatic control, good stability, that uses is safe, wide adaptability, and production cost of products is low, thermal efficiency height is the many electric cookers of a kind of cheap and good-quality intelligence.
