Description
Technical field:
The utility model relates to the energy-saving daily necessities of a kind of digitlization.
Background technology:
The traditional electrical fire-box is made up of " casing " and " simple and easy thermosistor ", and casing comprises paling frame, protection network, heating resistance wire, glass tube, glass tube installing rack, anti-hot plate and tank tower.The electricity fire-box powers up, the heating resistance wire heating, and the temperature inside the box raises, thereby arrives the purpose of heating.
But the traditional electrical fire-box is merely able to carry out coarse adjustment and temperature value the unknown of temperature, in use also exposes many problems:
1, simple and easy thermosistor needs continuous adjustment size repeatedly, just makes the temperature inside the box reach temperature required; Use very inconvenient.
2, because simple and easy thermosistor can not be regulated the temperature in the electric fire-box automatically, thereby hidden danger exists again, can cause fire, causes the loss of life and property.
Summary of the invention:
In order to solve above some deficiency, this use is novel to provide a kind of digitlization temperature control electric fire-box.This electricity fire-box is by the adjustment of carrying out of digitizing technique intelligence; temperature is carried out real-time monitoring display, set stationary temperature and show that constant temperature value, timing are warmed oneself, the automatic power-off protection of selection, high temperature and the high temperature alarm of intelligent heat energy diffusion temperature controlling point by keyboard input temp value; thereby improved the quality of heating in winter; improve heating comfort level and convenience, improved the security of warming oneself winter.
The scheme that its technical problem that solves the utility model adopts is:
The utility model digitlization temperature control electricity fire-box includes digitlization temperature control system and casing.The digitlization temperature control system comprises constant voltage source module, resistance wire control module, digital temperature sensor, keyboard, charactron display module, intelligent control module, buzzer warning and status indicator lamp.
The real time temperature acquisition scheme: utilizing intelligent control module that digital temperature sensor is carried out Temperature numerical must read.Digital temperature sensor is installed in box inside near protection network, and links to each other with conducting strip, increases the temperature acquisition area.Transmit the binary system temperature value by data wire and handle, thereby finish than the real-time collection of large tracts of land temperature and the transmission of data to the intelligent control module outside the casing.
Temperature shows and steady temperature is provided with displaying scheme: intelligent control module is passed to charactron and is driven the temperature binary numeral after reading, and drives charactron and shows decimal system Temperature numerical, thereby show real-time temperature value.Constant temperature numerical value is imported and is presented on the charactron by keyboard.
The selection scheme of constant temperature and intelligent heat energy diffusion temperature controlling point: before not reaching design temperature, the heating of the omnidistance controlling resistance silk of digitlization temperature control system control module, when temperature reaches more approaching temperature, carry out the PID modulation, through after stable with the accurate Toshiba of temperature within preset range, that is: change between design temperature-2 °＜design temperature＜design temperature+2 °, temperature can be controlled in the stable scope like this, and consider the influence of environment temperature to body metabolism, intelligent limiting temperature is below maximum 50 degree.By the rough calculation thermal expansion load degree that adds up of PID modulation and time, determine the temperature spot of cutting off the electricity supply, spend thereby make the maximum temperature that reaches after the heat energy diffusion of accumulation in early stage can not surpass the temperature value 65 that safety limits.
Buzzer warning and state indication scheme: intelligent control module is compared with the safety limiting temperature after gathering the digital temperature sensor temperature, drives the chimes of doom that buzzer sends " tick---ticking---" then; The state indication is by 5V voltage-stabilized power supply red led, system works green indicating lamp.When red led was bright, the supply of expression system power supply was normal; When red led goes out, system's non-transformer, whole digitlization temperature control system can't be worked, and can't heat in the casing, and is the same with indoor temperature.The system works green indicating lamp is bright or continually coruscate, and the expression whole system is working properly, if long-time long bright or long going out more than 5 minutes, the expression whole system goes wrong.When whole system went wrong, the resistance wire control module can't be worked, thereby can not give electricity, and guaranteed the safety of whole system.
Timing heating scheme: the timer of intelligent control module inside regularly to resistance wire control module switch regularly, thereby reaches the regularly purpose of heating.
Quantize energy-saving scheme: under the constant temperature situation,, thereby quantized energy-conservation by the selection of pid algorithm modulation and intelligent heat energy diffusion temperature controlling point.
The utility model digitlization temperature control electricity fire-box can be fixed on temperature control device on the electric fire-box case limit, can arbitrarily be placed on from the not far place of casing, can be placed on desktop or the like, and is convenient, flexible, quantized energy-conservationly on function, makes energy-conservation precision.
