Description

Multi-purpose pot controlled by one-chip computers

The utility model belongs to the family kitchen utensil, particularly electric heating boiling apparatus.

With the immediate prior art of the utility model be so-called " post bake formula pot for cooking rice " (seeing Yu Guoping chief editor " household electrical appliance complete works "), best heat time heating time of the curve that the simulation large stove is cooked heats, promptly earlier little fire heating, under the temperature of 30 degree, allow rice suction moisture content, and then make temperature rise to 98 degree, and be controlled at boiling under this temperature, and make β starch fully change α starch into, finish and cook through mending process such as cook a meal, cook rice over a slow fire again.This " post bake formula pot for cooking rice " compares with general electric cooker, and not only energy efficient, and the meal flavor look U.S. that cooks is one of at present senior kitchen utensils.The concrete technical scheme of this pot is used thermistor temperature detecting more, again by the control circuit temperature control, have in addition control with computer.But the greatest drawback of this pot is a function singleness, promptly can only be used for cooking, can not be used for the boiling of other food simultaneously, as cook congee, steam stewed, Baoshang etc., also have only a kind of pattern of cooking even cook, i.e. a heating curves, consumer for different taste can not select, simultaneously can not differentiated treatment for rice matter difference, as steamed rice, steamed brown rice, glutinous rice even kedgeree etc., obviously can not finish and cook with same heating curves.Owing to this pot function singleness costs an arm and a leg, therefore functional price popularizes and is subjected to certain restriction than low.

The purpose of this utility model provides a kind of multiple cooking function that has, can select the many of best heating curves automatically according to different needs and different situations again with pot, and possess the various advantages of existing senior electric cooker, electronic pot simultaneously, and cost is basic identical with existing senior electric cooker cost, and its functional price ratio is much higher than existing senior electric cooker.

The purpose of this utility model is achieved in that

Comprise pot shell 11 and enclosing cover 12 with pot more than of the present utility model, interior pot 13 and inner cap 14, thermoelectric heating device 21,22,23, thermistor 31,32 and composition such as control circuit, it is characterized in that having solidified 8 single-chip microcomputers 1 controlling software by a slice controls, be respectively equipped with thermistor 31 and 32 on the pot cover and the bottom of a pan, and connect with the digital translation interface of single-chip microcomputer 1, as mentioned above, for realizing multiple cooking function, at least being provided with five input control ends on the keyboard interface of single-chip microcomputer 1 connects with operating key 4, to realize that to many selections single-chip microcomputer 1 output control interface has at least two control output ends to control main thermoelectric heating device 21 and insulation thermoelectric heating device 22 respectively with the pot cooking function, 23.Certainly, above-mentioned 8 single-chip microcomputers 1 that solidified control software also can be replaced by single-chip microcomputer and a memory of having stored control software.Because function of the present utility model is more, identification when selecting and carry out for convenience, single-chip microcomputer 1 is provided with display interface and connects with LCD 2, to show the various functions and the duty of pot, is provided with the buzzer control end and connects with audible alarm with buzzer 3

The utility model adopts 8 single-chip microcomputers to control, hundreds of kind control mode can be provided, promptly can design hundreds of kind cooking control scheme, satisfy the needs of the various cookings, so many cooking needs are not necessarily arranged certainly at present, but along with growth in the living standard, various new cooking requirements will occur, and the utility model can also further expand according to new needs.The utility model is except increasing a slice singlechip chip and LCD, the parts of other pots do not need to increase, the various functions of pot then can realize by the design of software, and selectable leeway is bigger, so how the utility model is much higher than existing senior electric cooker with the functional price ratio of pot.

Description of drawings of the present utility model is described as follows in conjunction with the embodiments together:

Fig. 1 is the schematic appearance that present embodiment is used pot more;

Fig. 2 is the control circuit figure of present embodiment.

As shown in the figure, these many shells 11 with pot are the square of band cambered surface, enclosing cover 12 hinges are coupled on the shell 11, shell 11 is provided with heat-insulation layer, interior pot 13 surfaces are through oxidation processes, the inside coated fluororesin, inner cap 14 is installed on the installation shaft 15 on the enclosing cover 12, main thermoelectric heating device 21 is located at the bottom of shell 11, internally pot 13 heats, insulation thermoelectric heating device 22,23 are located at the middle part of enclosing cover 12 and shell 11 respectively, realize the internally comprehensive insulation of pot 13, operating key 4 and LCD 2 are positioned on the front of shell 11, the ST6041 chip that the single-chip microcomputer 1 of present embodiment adopts Thomson Co. to produce, keyboard interface are provided with five input control ends and connect with operating key 4, realize many with nine kinds of selections of pot; Thermistor 32 is located in the middle of the main thermoelectric heating device and is close to the interior the bottom of a pan, thermistor 31 is located at outer covering, two thermistors are realized the internally temperature measuring of pot 13, and two control output ends of single-chip microcomputer 1 are passed through relay 43 and controllable silicon 44 main thermoelectric heating devices 21 of control and insulation thermoelectric heating device 22,23 respectively after triode 41,42 amplifies; For avoiding being incubated of the influence of the civil power of electric heater, between triode 42 and controllable silicon 44, be provided with photoisolator 45 to single-chip microcomputer 1 and triode 42; When disconnecting, occur spark in order to eliminate relay 43, also be provided with the detection interface on the single-chip microcomputer 1, continue out or closure with the zero crossing of control relay 43 at civil power with closure; For guaranteeing many operate as normal with pot, below the thermistor 32 of shell 11 bottoms, be provided with the bottom of a pan switch 46, when interior pot 13 is placed on shell 11 in, depress thermistor 32(spring for interior pot 13) make the bottom of a pan switch closure, when interior pot 13 took out, the bottom of a pan switch 46(was by spring) disconnect; When making the outage when the short time, single-chip microcomputer 1 can be remembered the situation of boiling, can continue boiling when energising, rather than start anew again, can establish an accumulate electric capacity 47 in circuit, so that power to single-chip microcomputer 1 when outage.48 is integrated voltage stabilizers in the circuit, the 49th, and wave filter.In addition, because the clocking capability of single-chip microcomputer 1, how this can be designed to have timing function etc. with pot.

How present embodiment is work like this with pot: interior pot put into shell, by the gravity of interior pot with the bottom of a pan switch opens, select the scheme of the cooking again from the operating key input, single-chip microcomputer will according to the speed that temperature in the unit interval rises judge the material that will boil how much, selected then best heating curves, and contrast heating curves and the temperature of being measured by thermistor are high or low comes the disconnected or logical of control relay, boil thereby finish, then by the electric heat preservation of insulation.
