The technical problem that the utility model solves realizes by the following technical solutions:
A kind of controller that shows electric kettle based on the number of baroceptor, comprise microcontroller, temperature sensor, baroceptor, display unit, keyboard, nonvolatile memory, alarm and heating plate, the synthermal sensor of described microcontroller, baroceptor, display unit, keyboard, nonvolatile memory, alarm and heating plate link to each other, and described microcontroller provides operating voltage by the resistance-capacitance depressurization circuit.
Further, described display unit includes the charactron of indicator lamp and displays temperature.
Further, described microcontroller adopts MC20P24B single-chip microcomputer, 17 universaling I/O ports, 8 road reusable A/D mouths.
Beneficial effect:
The utility model is simple in structure, adopts the heating part of microprocessor control electric kettle, has overtemperature protection, anti-dry power down function, and must not normal water the boil shortcoming of outage of solution has multiple heat insulation function combination and personal settings.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model resistance-capacitance depressurization electrical block diagram.
The specific embodiment
In order to make realization technological means of the present utility model, creation characteristic, to reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of controller that shows electric kettle based on the number of baroceptor, comprise microcontroller MCU, temperature sensor, baroceptor, display unit, keyboard, nonvolatile memory, alarm and heating plate, the synthermal sensor of described microcontroller MCU, baroceptor, display unit, keyboard, nonvolatile memory, alarm and heating plate link to each other, and described microcontroller provides operating voltage by the resistance-capacitance depressurization circuit.Described display unit includes the charactron of indicator lamp and displays temperature.Described microcontroller MCU adopts MC20P24B single-chip microcomputer, 17 universaling I/O ports, 8 road reusable A/D mouths.
The electric kettle of microcontroller MCU in the utility model control shows by keyboard input and charactron, can receive multiple independent assortment setting or give tacit consent to Default Value, shows the temperature of water in real time, has dry combustion method warning, the water electric work energy of autotomying that boils.The utility model utilizes baroceptor to measure local air pressure, table look-up the boiling point of water outlet, adjust the temperature of water boiling automatically, by the different demands that different parameters adapts to different crowd are set.
In the utility model, provide operating voltage 5V by the resistance-capacitance depressurization circuit for microcontroller MCU, as shown in Figure 2, provide electric current I by the C1 decompression capacitor to load
0, in fact be exactly the charging and discharging currents I that flows through C1
C, the C1 capacity is more big, capacitive reactance X
CMore little, the charging and discharging currents that then flows through C1 is more big.As load current I
0Less than I
CThe time, unnecessary electric current flows through voltage-stabiliser tube ZD1.R1 is bleeder resistance should guarantee when selecting to release in the time that requires behind the power cutoff electric charge on the C1.R3 plays anti-surge breakdown effects, often selects metal oxidation resistance or the cement resistor in tens Europe.D1, D2, D3, D4 form full-wave rectification, and C2, C3, C4, C5 form filter capacitor.Model is the three terminal regulator U of 78L05
1For microcontroller MCU provides 5V power supply.
Embodiment 1, and the user can be directly strong by heating, and microcontroller MCU adopts the acquiescence mode to heat, and also can select functions such as automatic heat preserving, circulation heating, can also revise heating process parameters such as the time of boiling, and is arranged to personalized heating mode.In case heating process is selected, microcontroller MCU utilizes A/D port processing baroceptor numerical value, converts local water boiling point value to, opens the heating plate heating then, and detected temperatures sensor values in real time simultaneously converts temperature value to and is transferred to charactron and shows synchronously.After water boiling, spend the time of boiling and begin countdown, in order to evaporate more chlorine, when spending the time of boiling and being zero, close heating plate, alarm begins warning reminding simultaneously, reminds once 3 times altogether every 10 seconds.Nonvolatile memory is preserved the normal heating curve data, when water seldom or during dry combustion method, microcontroller MCU can close heating plate in the extremely short time.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
