Description

Electric cooker with phonetic warning device

The utility model relates to a kind of computer multifunction speech prompting electric cooker, belongs to the domestic electric heating cooker.

Electric cooker on the market has a spot of automatic control and adjustment in the process of cooking at present, give birth to ripe difficult grasp, cook congee or soup excessive easily, lack the precautionary measures, 93209170.9 of China Patent No. are called the voice electric cooker, on it by the sound circuit device of adorning an energy sounding, be subjected to the automatic control of electric cooker magnetic steel temperature limiter and gauge tap, the reminds people preparation of having a dinner from the voice, but it can not do the voice suggestion of multifunctional usage aspect, and function singleness only disappears in specified temp lower magnetic steel magnetic, just cut off the electricity supply, the cooking time started can not be set in advance.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provide a kind of computer multifunction speech to point out electric cooker, with the microprocessor is core, 12 kinds of cooking function characteristics are become number be stored on the microprocessor chip, comprise the voice restoration circuit, combine speech synthesis technique, make cooking overall process cooperate corresponding voice suggestion, carry out function corresponding and select and screen display, the combination of this integrated circuit makes peripheral cell minimum, and reliability improves.

Computer multifunction speech prompting electric cooker is made up of ectonexine pot body, microprocessor, electric heating plate, heating plate control circuit, LCDs, function key and loudspeaker; With the microprocessor is core, and wherein memory comprises that with various functional characteristics address voice and mutual contact process store in it, accesses corresponding program by function key, sets the different cooking project and the scheduled time with function key F1, F2, F3.There is venthole in the external portion of covering of electric cooker, inner cap is equipped with in its inboard, functional switch F4 is arranged between the exterior and interior cover, inner pot cover is pushed down following aluminum pot courage, makes its stressed following heating plate in its bottom that presses, and temperature sensor is equipped with in the center on the heating plate, inner cap is buckled in the outside wall surface place, upper end of hollow plastics pot body simultaneously, LCDs is equipped with in its front, and the computer microprocessor plate is contained in thereafter, and supply socket, loudspeaker and transformer also are equipped with in pot body hollow lumen bottom.Automatically controlled part is core with the microprocessor, it comprises microcomputer CPU, memory, controller, I/O interface, voice restoration circuit and amplifier, temperature, the time characteristic data of 12 kinds of cooking functions, 12 kinds of cooking titles and the voice of stage prompting and the various programs of this electric cooker operation are arranged, all be stored in the memory.

Be furnished with various speech explanations and prompting with speech synthesis technique in the microprocessor, cooperation by F1, F2, three keys of F3, from memory access voice through the I/O interface again to the voice restoration circuit, arrive loudspeaker Y1 again through amplifier again, along with each stage is arrived in the work of this electric cooker, just there are the speech or the sound that show this job specification to broadcast, up to end-of-job.

Temperature sensor detects the temperature of pot when the cooking, and with temperature value by I/O interface input microprocessor, microprocessor is made comparisons with these data and cooking data, make heating whether judgement through computing, as judge that heating then sends instruction, export the base stage that a high potential is given triode T1 by the I/O interface, T1 conducting in the heating control circuit has electric current to pass through the coil of relay J 1, the contact adhesive of relay J 1, heating plate is connected by the circuit of fastp-acting fuse B, should not heat as judging, microprocessor then sends instruction and exports the base stage that an electronegative potential is given T1 by the I/O interface, T1 ends, not adhesive of J1, the heating plate dead electricity, pot is known from experience the nature cooling.

By F1, F2, F3 function key various parameters are presented on the LCDs.This electric cooker adopts fuzzy control technology, and heated perimeter is enlarged, the control accuracy height, thus cooking function, power saving capability and the effect of electric cooker are significantly increased.

Advantage and effect:

1. the needed temperature of various cooking functions, time deposit in the microprocessor memory, and sensor thermometric is at any time arranged, and do fuzzy logic control by computer.

2. the electric cooker outer pan body is that plastics are made, and can not get rusty, and has prevented the accident of human electric shock simultaneously, and is safe and reliable, and interior pot courage inwall scribbles teflon coating, and pot inwall coefficient of friction reduces, and makes the food non-stick pan.

3. utilize the characteristics of the thermal capacity of object, change the constant interrupted heating that is heated to be, saved energy consumption.

4. the dry combustion method accident can not take place, safe in utilization, open pot cover, functional switch F4 disconnects, and it is electric that heating plate can not be got, and in the heating process, no matter when which kind of reason overtemperature to occur owing to, fastp-acting fuse will cut off heater circuit, play a protective role.

5. multiple functional, 12 kinds of cooking functions are arranged, see shown in the LCDs, can select multiple cooking method arbitrarily, can be scheduled to the cooking time, easy to operate, be suitable for popularization.
