The utility model has the advantages that the circuit design is simple, the cooking vessel has the functions of intermittent oscillation switching and timing boiling, the automation of cooking rice and porridge, decocting soup, steaming and stewing is realized, work is sensitive and reliable, the use is easy, clean and sanitary, and the cost is low.

Description

Multi-purpose energy-saving and temp. controlled electric cooking vessel

The utility model relates to a kind of family expenses electric cooker, particularly a kind of temperature control energy-saving multi-purpose meal pot with intermittent oscillation switching function.

At present, electric cooker mainly contains two types, and a class is common electric cooker, has only automatic rice-cooking function, and the water of cooking congee, stew soup, stew all can not be jumped automatically and be pulled, overflows easily, the inconvenience of boiling, function singleness; Second class is luxury fully automatic rice cooker, and computer is controlled automatically, timing automaticly cook, cook congee, stew soup, multiple functional, but the control structure complexity involves great expense, and is difficult to promote.The applicant has " electric energy-saving is used electric cooker more ", " two-tube energy-saving multi-purpose electric cooker ", " buck multifunctional electric rice cooker automatically " patent, the multi-form automatic step-down temperature control technique of main employing, electric cooker is had automatically cook, cook congee, stew soup, steam stewed function, the scope of application is big, the automaticity height.

The purpose of this utility model provides a kind of improved temperature control energy-saving multi-purpose electric cooker, utilizes time switch, thermoswitch and intermittent oscillation switch to jointly control, and can heat by continuous or automatic conversion timing intermittently power-on, realizes multifunctional self-regulating.

The purpose of this utility model can realize by following measure: this electric cooker is based on the common electrical meal, set up timer and temperature control pause switch circuit, timer is connected with temperature control pause switch circuit, temperature control pause switch circuit connects heat-generating disc, heat-generating disc is connected with temperature limiter, warmer, and temperature control pause switch circuit is made up of thermoswitch and intermittent oscillation switch in parallel.When cooking, timer is screwed into feed-through locations, more can finish the insulation of cooking automatically, in the time of need cooking congee or steam the boiled dinner thing, timer is screwed into scheduled time position, when seething with excitement in pot, thermoswitch disconnects, and electric current is gone into heat-generating pipe through the intermittent oscillation switch, and conducting at the intermittence heating of intermittent oscillation switch periods ground makes and keeps little boiling in pot, Preset Time finishes, and boils and finishes automatically.

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

Fig. 1 is the circuit diagram of the utility model embodiment one;

Fig. 2 is the circuit diagram of the utility model embodiment two.

Below with reference to accompanying drawing one utility model is described in further detail: this electric cooker covers heat-generating disc, temperature limiter, warmer by pot body, pot courage, pot, and timer and temperature control pause switch circuit are formed, and the circuit diagram of embodiment one, two is seen Fig. 1, Fig. 2, heat-generating disc R ₁With temperature limiter K ₄, warmer K ₅Connect the timer K of embodiment one ₁Straight-through contact A connect heat-generating disc R ₁, K ₁Timing contact B connect heat-generating disc R through temperature control pause switch circuit ₁, temperature control pause switch circuit is by thermoswitch K ₂With the intermittent oscillation K switch ₃Compose in parallel, only in timer timing on-state, temperature control pause switch circuit just works the sort circuit structure; The timer K of embodiment two ₁Timing contact B all be connected heat-generating disc R with straight-through contact A through temperature control pause switch circuit ₁In the design of intermittent oscillation switch preferably per 60 seconds, conducting 12 seconds was by 48 seconds, the time ratio of promptly connecting power supply and powered-down is 1:4, and during the electric cooker intermittently power-on, its heating power is equivalent to 1/4 of former power like this, make congee in pot, soup etc. outwards do not overflow.

Control circuit simplicity of design of the present utility model, have regularly boil, automatic control intermittent oscillation switching function, work is sensitive, reliable, can cook, cook congee, stew soup, steam stewed automatically, easy to use, food can be not excessive, clean hygiene, energy-saving effect is remarkable, and the product cost is low, implements to promote easily.
