Description

The hot electric blanket of speed

Described technical field

It is electric blanket that the utility model relates to an a kind of flexible electric heating that is used for the last heating of bed, particularly a kind of this hot electric blanket.

Background technology

Existing electric blanket by attaching plug, control switch, be uniformly distributed in heating wire in the flexible blanket and be electrically connected and be connected into the loop and constitute.For guarantee electric blanket in use temperature can be in the scope of human comfort, maximum temperature must not exceed the tolerant degree of human body, the power of heating wire is that Electric heat matress for double bed the most very much not exceeds 150W, single electric blanket the most very much not exceeds 75W, long especially under such power from energising begin to generate heat time of needing when reaching the comfortable temperature of human body sensory, generally more than half an hour, it is very inconvenient that the user feels, must open electric blanket in advance, if hora somni(hs) is just opened electric blanket, can only icyly fall asleep, just warm as to get up for a long time.

Summary of the invention

In order to overcome existing electric blanket long shortcoming warm-up time, the utility model provides a kind of speed hot electric blanket, can be in the short time (such as 4-10 minute), and reach human body and feel the humidity of warming up, exempt preheating and rise the trouble of wet difficult stand-by period, can promptly open promptly sleeping.

The technical scheme that its technical problem that solves the utility model adopts is: by attaching plug, control switch, be uniformly distributed in heating wire in the flexible blanket and be electrically connected and be connected in the existing electric blanket in loop, its heating wire is changed into two and is uniformly distributed in side by side in the flexible blanket by single being uniformly distributed in the flexible blanket, its control switch be with by high-grade (power supply lead directly to heating wire), low gear (power supply by diode series connection rectification then switch on heated filament), close and keep off the existing general control circuit of the path of heating wire (cut off the electricity supply with), change into fast thermal control circuit.After changing fast thermal control circuit into, when opening electric blanket, heating wire in the electric blanket is connected into series connection by fast thermal control circuit, when depressing fast hot button, the speed thermal control circuit becomes two heating wire into state in parallel by series connection, in the heating wire of the logical people's parallel connection of power supply, in 4-10 minute, the speed thermal control circuit is two series connection with heating wire by two recovering states in parallel automatically, in the heating wire of logical two series connection of people of power supply, power during two heating wire series connection is the same with the power of existing electric blanket, power when two heating wire are in parallel is 4 times of power of existing electric blanket, reach the purpose of rapid intensification, and the length of heating wire is the twice of former heating wire substantially, unit length power constant substantially, heating wire is evenly to distribute in flexible blanket, the power of unit are improves 4 times when starting, not influence of safety to heating wire and flexible blanket, and the starting time is very short, reduce to the power of existing common electric blanket behind the proceed-to-send, fast thermal control circuit in its control switch adopts delay circuit, flexible blanket 1 interior two heating wire arranged side by side 2 are with an end of 3 and connect the back and be connected with an end of switch 4 among Fig. 1, the other end of switch 4 is connected with an end of switch 5, and be connected with the input 7 of 220V power supply, the other end of heating wire 2 arranged side by side is connected with an end of the other end of switch 5 and switch 6, being connected of the other end of the other end of switch 6 and heating wire arranged side by side 3, and be connected with another input 8 of 220V power supply simultaneously.Electric blanket is when the hot state of speed, and fast thermal control circuit is the time-delay state, and switch 5 disconnects, and switch 4,6 is connected, and in 4-10 minute, delay time finishes, and delay circuit reverts to normality, and switch 5 is connected, and switch 4,6 disconnects.Switch 4,5,6 can be relay, controllable silicon, etc., its time-delay control section can be electronic delay circuit (comprising analog circuit, digital circuit or single chip machine controlling circuit), produce time delayed signal by electronic delay circuit, drive relay or trigger controllable silicon, make relay adhesive or disconnection or controllable silicon conducting or end, reach switch 4,5,6 and be switched on or switched off by the delay time of setting up.

The beneficial effects of the utility model are: overcome existing electric blanket long shortcoming warm-up time, used this fast hot electric blanket, can just open electric blanket at hora somni(hs), brought great convenience to the user.
