Fig. 1 is that the energy of heating blanket in first embodiment of the invention supplies the circuit diagram that control unit, operating unit and each unit are connected to each other；
Fig. 2 is the schematic diagram of the second embodiment, in the operating unit that some of them change is embedded in Fig. 1；
Fig. 3 is the detailed perspective view of the heating element heater included in the operating unit shown in Fig. 1 and Fig. 2.
Detailed description of the invention
The following detailed description relates to the specific embodiment of the heating blanket in a present invention, is not limiting as its content.
As shown in Figure 1, depict a circuit, realizing connecting by a connection cable only comprising two conductors 510 and 520 between one of them energy supply control unit 300 and operating unit 400, wherein said operating unit 400 provides an AC voltage, if frequency is 50-60Hz.Operating unit 400 is made up of fabric sheet, has a heating element heater 100 wherein, and this heating element heater 100 is had the conductor 101 and 102 of 4 relevant end component A, B, A1, B1 and constitutes successively by two other.It is shown specifically as in Fig. 3, heating element heater 100 is made up of the polyester fiber 105 in fabric fibre, first conductor 101 it is wound with on it, it is coated with the first electric heating insulation component 103 being made up of polyethylene, on it, spiral winding has the second conductor 102, and the electric heating insulation component 104 that entirety is made up of PVC by is wound around.The first conductor 101 in heating element heater 100 and realize electrically connect by respective end component A and B between the second conductor 102 with energy supply control unit 300, and each relative to end component A1, B1 between realize electrically connecting a common node 110.
Described heating element heater 100 is electrically connected according to the scheme provided in Fig. 1, and only with two end component A and B for driving；The first end component A(in heating element heater 100 passes through conductor 520) electrically connect with an energy supply stage, the second end component B(in heating element heater 100 passes through conductor 510 simultaneously) electrically connect with node 209, to connect into three network H1, the circuit of the energy supply control unit 300 of H2 and H3, described energy supply control unit 300 is provided energy by and off switch 301, and has the feature that
A) first network H1 provides the supply of negative electrode half-wave and an electric mechanical switch 202 and diode 201 to be connected in series wherein,
B) the second network H2 passes through a switch element 203 and the series connection of diode 205, it is provided that the supply of anelectrode half-wave,
C) the 3rd network H3 has the characteristic that the position signalling the being switched on or switched off conversion of electric mechanical switch 202 is switched to circuit 206.
In the first paragraph Preset Time of TPH time, heating blanket operates, and such as 30 minutes, during this period of time, electric mechanical switch 202 is in the position of connection, and circuit 206 maintains switch element 203 to be constantly in on-position.So, two half-waves (positive and negative) are provided to heating element heater, to obtain its peak power.
In this way, heating blanket (being 28 degrees Celsius already provided with preset temperature threshold value T2) in the present invention has been idle at least 15 degrees Celsius, and providing in the case of above-mentioned with by the heating element heater 100 of bipolar electrode peak power already provided with electric mechanical switch 202 and switch element 203, heating blanket only just reached 30 degrees Celsius needed in 10 minutes.
Once terminating preheating time and electric mechanical switch 202 is in on-position, circuit 206 meeting roof-cut resistence element 203, interruption bipolar electrode is to the supply of heating element heater 100, and allows single electrode to supply, and so causes the half of power to be provided to heating element heater 100.Therefore, until electric mechanical switch 202 keeps the position being in connection, it is only possible to reduce the power being supplied to heating element heater 100 with less than the 50% of normal value.
Contrary, when electric mechanical switch 202 is in open position, it is provided that to the power of heating element heater 100 can between 5% ~ 50%, and may by button 207 send a signal to circuit 206 with activate with alternate cycles switch on and off switch element 203.It is supplied to the change between 5% ~ 50% of the percentage ratio of power of heating element heater 100 and is the type by heating blanket and specification determines.The power in the present invention use type of heating blanket less than 50%, is especially advantageous, when user is intended to be placed in one order the position of one continuous use, uses such as night.
The most also depicting NTC type temperature sensor 208 and be embedded in energy supply control unit 300, it measures the internal temperature T1 being positioned in control unit 300.By presetting a critical temperature value T2 in energy supply control unit 300, such as 28 degrees Celsius, measured when on and off switch 301 is in on-position, this makes the temperature value T1 and this critical temperature value T2 of comparison detection be possibly realized.When T1 is more than T2, being i.e. exceeded when critical temperature, and simultaneously electric mechanical switch 202 is in on-position, circuit 206 will not activate switch element 203 to avoid providing like this anelectrode to heating blanket and therefore to increase the power of heating blanket and reach its maximum.Inventor is surprised to find that an advantage, service time according to heating blanket, internal temperature in control unit increases to a certain temperature value exceeded, by the internal temperature in measure-controlling unit, avoid the danger that the overtemperature situation on the heating blanket surface caused due to mistake is brought, but, can suitably predict, the use of the heating blanket in the present invention is closed mistakenly by user or resets the function of peak power (such as, he/her selects electric mechanical switch 202 to be in on-position), when heating blanket is in the case of the most awfully hot；Or under other same cases, when electric mechanical switch 202 is already at on-position, he/her closes and resets on and off switch 301 in a short period of time.
The further feature of the temperature value T1 measured, when being detected by sensor 208, it allows to change the TPH time to supply positive half-wave to switch element 203.
Such as, when a critical temperature value T2 is preset, such as 28 degrees Celsius, further, when at the internal temperature measured by cabinet interior, when on and off switch 301 and electric mechanical switch 202 are switched on, can be less than 15 degrees Celsius, the electrode supply of the second network H2 has the TPH time of lasting 45 minute；When temperature T1 includes the temperature between 16 degrees Celsius and 20 degrees Celsius, this persistent period can allow to be 30 minutes；When T1 includes the temperature between 21 degrees Celsius and 25 degrees Celsius, this persistent period can allow to be 20 minutes；When T1 includes the temperature between 26 degrees Celsius and 28 degrees Celsius, this persistent period can allow to be 10 minutes, and finally, when T1 is higher than 28 degrees Celsius, this persistent period can allow to be 0 minute.
It will be evident that the time-quantum method of reference temperature and initial value are to change according to about the model of heating blanket or the particular requirement of its energy supply control unit size.
Also show the current insurance silk 204 position in energy supply control unit 300 in FIG, and the position that current insurance silk 204 is in operating unit 400, connect with heating element heater 100, this electric fuse can control any possible abnormal conditions relevant with overload, such as, due to incorrect use or superheated the first electric heating insulating barrier 103 of causing due to the aging of thin plate, the heating element heater in described thin plate may be caused to migrate, thus reach to overcome its fusing or softening temperature, and form the short circuit between two conductors 101 and 102.
In FIG, the electric mechanical switch 202 of the heating blanket in user selects the present invention is in open position to continue or evening hours use, circuit 206 meeting closing switch element 203 after a predetermined TASO time cycle, heating blanket is in use in the meantime, such as 6 hours regular time.Once the TASO time cycle terminates, and heating blanket can decommission, and this is the reason for safety and node.
Be automatically switched off the calculating of time cycle to be designed in circuit 206, by two different schemes: a) when by and off switch 301 supply energy to control unit 300 open time, the time of being automatically switched off starts counting up；Or b) when electric mechanical switch 202 is closed by user, the TASO time starts counting up, thus the use cycle that persistently use or night use starts.By above-mentioned layout, heating blanket is only closed by TASO intervalometer when electric mechanical switch 202 is in open position.
In fig. 2, except switch element 302 in addition to 303 consistent with Fig. 1, for the heating blanket being automatically switched off in the present invention, as a replacement of the embodiment shown in above-mentioned Fig. 1.In chart in fig. 2, when control unit 300 being connected by and off switch 301, the TASO time starts counting up.Chart in Fig. 2 depicts two different embodiments that the TASO time arranges, depends on whether that switch element 302 or switch element 303 are used for connecting valve element 203.
It practice, in the first embodiment, Fig. 2 depicts the switch element 302 of a bipolar electrode type, such as TRIAC or rele, is controlled by circuit 206.The TASO time is controlled by circuit 206 by switch element 302；No matter electric mechanical switch is selected at on-position or open position, and heating blanket all completely closes.
In a second embodiment, Fig. 2 depicts another switch element 303, and this switch element is connected with diode 201.Switch element 303 opens the supply circuit (negative half-wave) of network H1.Once the TASO time cycle terminates, and electrical control circuit 206 simultaneously closes off switch element 303 and switch element 203, thus heating blanket completely closes, and no matter electric mechanical switch 202 is selected at on-position or open position.
Under any circumstance, the described TASO time can simply be a predetermined time cycle (such as 6 or 9 hours), or the most not in energy supply control unit 300, this makes to arrange the different TASO time in control circuit 206 and is possibly realized (such as 3 hours, 6 hours, 9 hours).Under any circumstance, close the control circuit 206 of switch element 203 and 303 while heating blanket is worked as TASO time-interleaving and guaranteed electric blanket closedown to be also switched off.
Certainly, for those persons skilled in art, deformation and the change of many preferred embodiments are apparent from, and it still irons within the scope of the invention.
Therefore, the present invention is not limited to the preferred embodiment described, and is only described by embodiment and is not intended to, but is defined by claims below.
