Abstract
The utility model belongs to a domestic appliance product. Most of the past electrical blankets can not adjust the range of the temperature and keep the constant temperature automatically. The important technical characteristic of the utility model is that a temperature induction circuit is composed of an electronic element and a temperature sensor. The temperature of the electrical blanket can be adjusted within the range of 28 DEG C-45 DEG C, wherein, the utility model keeps the constant temperature at the arbitrary temperature scale automatically.
Description
This utility model belongs to household electronic products.
Mostly existing electrical blanket is can not mode or power control formula, can not mode to have temperature non-adjustable, temperature rise, comfortableness difference and waste electric power easily cause the weakness of fire.Though power control formula improves to some extent in design, but can not be implemented in homothermic requirement on a certain temperature.
The purpose of this utility model is to design a kind of new electrically heating blanket, and this blanket has temperature can be in harmonious proportion the function of automatic constant-temperature.Can be between 28 ℃-45 ℃ arbitrarily adjust, and homothermic characteristics on the arbitrary temp betwixt.For realizing this characteristics, this utility model has used electronic control circuit and the temperature sensor of TM-1 type.Its operation principle is as shown in drawings: K be double-pole switch, R2 be heating wire, 1 for diode, 2 for thyratron, 2EF be that light emitting diode, R1 are that dropping resistor, RW are that potentiometer, TM-1 are temperature sensor.When connecting K switch, alternating current comes and goes conducting by 1.2 two pipe fittings.When temperature rises to uniform temperature.The increase of temperature sensor resistance makes the not conducting of pin current potential rising thyratron of thyratron 2, temperature sensor resistance reduces pin voltage and descends when making circuit only form the unidirectional conducting of KRL1 to be reduced to uniform temperature, thyratron is resumed work, thereby reaches homothermic purpose.
Adopting circuit shown in the accompanying drawing, will be to implement this novel best approach.
Claims (1)
- A kind of electric blanket is characterized in that temperature-control circuit is in parallel by divider resistance, light emitting diode, potentiometer, temperature sensor series connection back and diode, thyratron, is composed in series with heating wire, switch more at last.
