Description
Technical field
The utility model relates to a kind of electric heating appliance, especially can automatically regulate the electric blanket of temperature and heating position.
Background technology
Along with the raising of people's living standard, the people of use in winter electric blanket is more and more.Electric blanket energising can the evolution of heat can improve bed clothes temperature, can to bed clothes, go tide to dry in wet weather simultaneously, and its power consumption is few, easy to use, has become the selection in winter of more and more families.
Existing electric blanket is most of adopts special soft cable-styled heating to be in the gap that snake-coiled type inweaved or sewed up electric blanket, and energising gets final product the evolution of heat.The general method that adopts different gear regulation heating amounts.
Due to when sleep, most people the most comfortable temperature is 32 ℃ of left and right, and occurs small size variation along with people's age and condition and climate change.
The common electric blanket that sell in market now has two problems, is first to open all heat-generating units of rear electric blanket all at persistent fever, no matter whether has people in sleep, even if surpassed the best sleep of human body temperature, still continues heating.Cause like this waste of electric energy, while also allowing people sleep, produce uncomfortable sense, also easily cause bed clothes to burn out simultaneously, even occur the danger of fire.
When next is existing electric blanket work, heating position, all in heating, can not accurately be controlled in all positions of electric blanket, can cause like this waste of electric energy, also can cause components and parts and electric blanket Acceptable life to reduce simultaneously.
So need to design a kind of novel electric blanket that can automatically regulate temperature and heating position, solve the problems referred to above, in use crowd due to electric blanket, have is much old man and child simultaneously, when realizing above function, operation can not be too complicated loaded down with trivial details, so need to design a kind of electric blanket simple to operate with easy to use.
Summary of the invention
In order to address the above problem, the utility model provides a kind of electric blanket that can automatically regulate temperature and heating position, when opening electric blanket, bed clothes temperature is controlled within the scope of 25 ℃-30 ℃, makes bed clothes insulation; When there being people in bed, the bed clothes temperature of people position is controlled within the scope of 28 ℃-33 ℃, according to the change of human body sleep posture, change heating position simultaneously, make human body position temperature all-the-time stable in the suitableeest sleep temperature left and right.When realizing the accurate control of temperature and heating position, the operation of electric blanket is still simple and convenient.
The utility model solves the technical scheme that its technical problem adopts: a kind of electric blanket that can automatically regulate temperature and heating position, comprises AC-DC circuit, relay, system control unit, temperature sensor, pressure sensor, heat-generating units, indicator lamp, amplifier, switch, city's plug, resistance; AC-DC circuit is electrically connected to city's plug; System control unit is electrically connected to relay, and relay is electrically connected to heat-generating units; System control unit is electrically connected to indicator lamp; Temperature sensor is electrically connected to system control unit; Pressure sensor is connected with system control unit electricity through amplifier; Switch is electrically connected to AC-DC circuit.
Indicator lamp: show that whether electric blanket is in running order.
System control unit: according to the working condition of the Data Control relay of temperature sensor and pressure sensing collection, thus the duty of change heat-generating units.
Temperature sensor: detected temperatures.
Pressure sensor: detected pressures.
Amplifier: the signal of pressure sensor collection is amplified and transfer to system control unit to process.
Switch: circuit general switch.
The beneficial effects of the utility model are: heating position and the heating temp that can accurately control electric blanket; Open after electric blanket, can realize the in the situation that of unmanned sleep bed clothes temperature is controlled to 25 ℃-30 ℃, keep the warm of bed clothes; When there being people in bed, along with the variation of human body sleep posture, change the heating position of electric blanket, make regional temperature all-the-time stable that people sleeps at 28 ℃-33 ℃.The utility model can be controlled temperature, not only can reduce the possibility that burns out sheet or fire, can also allow user more comfortable, safer, more power saving simultaneously, and electric blanket is used more convenient.
Accompanying drawing explanation
Below in conjunction with structural representation and physical circuit figure, the utility model is further illustrated.
Fig. 1 is embodiment schematic diagram of the present utility model.
Fig. 2 is the utility model embodiment circuit part schematic diagram.
Fig. 3 is the partial circuit schematic diagram of the utility model embodiment.
1. heat-generating units in figure, 2. pressure sensor, 3. temperature sensor, 4. system control unit.
The specific embodiment
In Fig. 1, system control unit is positioned at electric blanket outside, with user-friendly; Electric blanket is similar to and is divided into a plurality of regions, and there are heat-generating units, pressure sensor and temperature sensor in each region; A plurality of pressure sensors and temperature sensor are evenly distributed in electric blanket, send to system control unit to process the data of collection; Whether system control unit changes the duty of relay, thereby control heat-generating units, work.
In Fig. 2, AC-DC circuit becomes 220V alternating current into 5V direct current; System control unit is mainly single-chip microcomputer STC90C58AD, packing forms SOP-40; Indicator lamp is selected common low power LED; Relay uses JQC-3f.
In Fig. 3, temperature sensor is selected DS18B20, packing forms TO-92; Pressure sensor uses FlexiForce A201-100, and through amplifier MCP6001, by signal input system control module, when pressure sensor output voltage surpasses setting value, amplifier is output as low level (0V); When pressure sensor output voltage is less than setting value, amplifier is output as high level.
With the bright of indicator lamp D1, represent that electric blanket is in duty.
Whether switch S 1 is controlled and to single-chip microcomputer, is powered.
Specific works mode is as follows: as turn on-switch S1, electric blanket enters duty.AC-DC circuit is converted to 5V direct current supply circuit by 220V alternating current and uses, and indicator lamp D1 is bright; Now bed clothes temperature is lower, temperature sensor detects temperature now lower than 25 ℃ of the minimum holding temperatures of setting, thereby control relay is closed, make resistance wire RH1, RH2, RH3, the RH4 heating of heat-generating units, when bed clothes temperature reaches 30 ℃, Single-chip Controlling relay disconnects, and the heat-generating units in this region quits work, and then bed clothes are stabilized within the scope of 25 ℃-30 ℃.
When people lies on electric blanket in bed, pressure sensor detects pressure position, first detects this regional temperature, if this regional temperature lower than 28 ℃, system control unit control relay is closed, near heat-generating units heating.When temperature sensor detects temperature and reached 33 ℃, control relay disconnects, and near heat-generating units quits work.Along with the change of people's sleeping posture, pressure sensor detects the position of people on electric blanket, controls corresponding electrothermal wire heating, makes people's region temperature of sleeping maintain all the time 28 ℃-33 ℃.
Nobody is incubated in bed to reach bed clothes by the way, has near the people's object of the temperature temperature of optimum sleep quality in bed.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only; and part embodiment; for the person of ordinary skill of the art; do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, all belong to protection domain of the present utility model.
