Description
Technical field
The electric blanket of heating power supply is automatically controlled based on temperature change in quilt the utility model is related to a kind of, belongs to house
Electro-technical field.
Background technology
Electric blanket, also known as electrical blanket, are a kind of contact electric heating appliances, it will be special, and insulating properties reaches the soft rope of standard
Formula heating element is woven into disk serpentine or sews up in woollen blanket, and when energization gives off heat.When being mainly used for people's sleep, quilt is improved
Temperature in nest achievees the purpose that heating, it may also be used for bedding removes moisture dehumidifying.Its power consumption is few, and temperature can be adjusted, and be made
With facilitating, using extensive.At present, existing various electric blankets acquisition national patents, old man, pregnant woman, child can pacify
It entirely uses.
With the development of science and technology, sensor, temperature controller is widely used.Sensor substitutes people and obtains various letters
Breath, when receiving information change, passes information to control section, so as to the reception condition feedback control according to signal.This
Technology has very extensive application in China, it may be said that quite ripe.
The great development of temperature controller and the one of scientific and technological progress stride greatly.The measurement control model of temperature controller is wider,

100%, return difference：1 ~ 30 DEG C of temperature, sensor error amendment：- 50 DEG C of temperature~150 DEG C.The display mode of temperature controller is three
Position LED charactrons show there is a decimal, and it is convenient to read, and control is simple.
Now there are two types of electric blankets on the market, one kind is temperature-adjusting type, and one kind is temperature control type.
So-called temperature-adjusting type, that is, we saw most, common, heating method used is thermal balance
Formula, belongs to opened loop control, and under this mode, the effect of heating is influenced by environment temperature.Because temperature regulating type electrothermic mattress tune is
Output power, the heat that it is sent are constant.This electric blanket is generally not suitable for using whole night.Therefore temperature adjustment before sleeping
It is too high in evil case, but do not heighten, it often just has to morning and is frozen awake situation.
Temperature control type belongs to closed-loop control, is constant temperature degree rather than determines caloric value.It is less than your setting value in blanket temperature
When, setting value can be heated to automatically, when reaching setting value, can be automatically stopped heating, so your quilt temperature is by extraneous temperature
The influence of degree is not very big, lies substantially in a fixed temperature range set by you.Use the sense of temperature control type electric blanket
Feel, just as sleeping on heated kang.

The operation principle of the utility model is：
The temperature sensor IC1 is used for detecting quilt temperature, the output voltages of 3 feet with the rising of environment temperature and
Increase.
When temperature is 30 DEG C in quilt, the output voltage of N4 is 2V, and each output terminals of IC5 export low level, VL1~
VL10 is all lighted, and instruction temperature is 30 DEG C.
S is temp control switch.When S is placed in " 1 " position, temperature controller 2 shows environment temperature in quilt, and S is put
When " 2 " position, control temperature can be set by adjusting the resistance value of potentiometer RP2.
Such as the temperature if desired controlled is 25 DEG C, then should S first be placed in " 2 " position, adjust RP2, the positive for making N5 is defeated
People end (12 feet of IC3) voltage is 1V, and VL1~VL5 is made to light；Then S is placed in " 1 " position, temperature controller again
The environment temperature in quilt is controlled according to the temperature value of setting (should set control temperature according to actual needs during use
Degree).
When environment temperature is less than 25 DEG C in quilt, N4 output voltages are less than 1V, and N5 output high level turns on VD1, double
Trigger Al inside time-base integrated circuit IC4 is overturn due to 2 feet and 6 feet add people's high trigger pulses, and 5 feet export low electricity
Flat, K is attracted, and normally opened contact connects the working power of electric heating equipment, and environment temperature is made to increase.VL11 is lighted simultaneously, is referred to
Show that electrical heating is set respectively working.8 feet of IC4 and 12 feet are low level at this time, and 9 feet export high level, and VL2 does not shine.
When environment temperature is more than 25 DEG C in quilt, the output voltage of N4 is higher than 1V, and N5 is made to export low level, and VD1 ends,
IC4 internal triggers A1 is overturn again, and the working power of electric heating equipment is cut off and stops heating by 5 feet output high level, K releases,
VL11 also extinguishes.At the same time, IC4 internal triggers A2 is overturn due to 8 feet and 12 feet generation high trigger pulses, the output of 9 feet
Low level, VL12 are lighted, and instruction electric heating equipment is in off-position.
After electrical heating sets each power-off, environment temperature is begun to decline again, and when temperature is less than 25 DEG C, K is attracted again, makes electrical heating
Equipment energization work starts to heat, and so in cycles, temperature in quilt is made to be maintained at 25 DEG C or so, human body is more comfortable ripe
Sleep environment.
It when using electric blanket, whether test temperature controller can work normally, can adjust the resistance value of RP2, setting 25
S after temperature, is placed in " 1 " position by DEG C temperature in order to control, then is heated with hair dryer against IC1, if VL1~VL6 light one by one and
After VL6 is lighted, K is discharged rapidly, and VL12 shines, then illustrates that the temperature controller can work normally.
Specific embodiment of the utility model is explained in detail above in conjunction with attached drawing, but the utility model and unlimited
