Description
Technical field
The utility model relates to a kind of constant temperature wax melter, particularly relates to a kind of control circuit of constant temperature wax melter.
Background technology
Constant temperature dewaxing candle stove is the special equipment that hearing aid industry making audiphone shell and ear-drum dip in ceroplastic, it adopts the heating of PTC element heating element usually, there is the feature rapidly that heats up, there is again automatic constant-temperature function, the flames of anger simultaneously, use safety, reliability are high, the feature of long working life.
Chinese patent Authorization Notice No. is CN2693775Y, authorized announcement date is that the utility model patent on April 20th, 2005 discloses a kind of paraffin melter, include base, shell, heater element, resistance, its housing is fixed on base, heater element is contained in the hollow cavity of shell, resistance is fixedly mounted on heater element, and is connected with power supply by power line.Although the paraffin melter of said structure can control the heating-up temperature of dewaxing in actual use easily, grasp the thawing degree of wax stone, but there is hot overshoot phenomenon in use in it, heating is stopped even if cutting off the electricity supply, but the inertia that heater element brings can make temperature continue to leap high, the amplitude of leaping high is variant because of the factor such as power and environment temperature of heater element, to be heated overshoot effect, temperature fluctuation amplitude is large, frequently need carry out temperature control adjustment, therefore there is the lower defect of temperature-controlled precision and problem in the paraffin melter of said structure.
Utility model content
Technical problem to be solved in the utility model is to provide the control circuit of the higher constant temperature wax melter of a kind of temperature-controlled precision.
For solving the problems of the technologies described above, the utility model provides a kind of control circuit of constant temperature wax melter, comprise temperature control unit, power supply indicator, bidirectional triode thyristor, burner on light, main heating group, auxiliary heating group and thermocouple;
Wherein: described power supply indicator, described bidirectional triode thyristor, described main heating group, described auxiliary heating group are connected with described temperature control unit respectively with described thermocouple;
Described bidirectional triode thyristor is serially connected in the ac circuit at described auxiliary heating group place for controlling the duty of described auxiliary heating group;
Described heating instruction is in parallel with described auxiliary heating group.
Described temperature control unit also has and multiple exercisable button is set.
Described temperature control unit also has the display screen for displays temperature.
Described temperature control unit is also connected with switch and the supply socket with insurance.
Temperature detect switch (TDS) is in series with between the positive electrode of described supply socket and described temperature control unit.
Compared with prior art, the beneficial effects of the utility model are: because the utility model has main heating group and auxiliary heating group, when bringing into use, main heating group and auxiliary heating group work simultaneously and wax melter are rapidly heated, after reaching uniform temperature, close main heating group and stop heating, only deposit auxiliary heating group and continue to be heated to preset temperature, thus waste heat and thermal inertia can be reduced, to reduce the impact of hot overshoot, thus accurate temperature controlling.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model.
In figure: temperature control unit 10, power supply indicator 5, bidirectional triode thyristor 7, burner on light 8, main heating group 4, auxiliary heating group 9, supply socket 1, switch 2, temperature switch 3, thermocouple 6.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with embodiment and accompanying drawing, the utility model is described in further details.At this, exemplary embodiment of the present utility model and illustrating for explaining the utility model, but not as to restriction of the present utility model.
Shown in Figure 1, the control circuit of a kind of constant temperature wax melter of the present utility model, comprise temperature control unit 10, this temperature control unit 10 has and multiple exercisable button and the display screen for displays temperature is set, also be connected with power supply indicator 5 simultaneously, bidirectional triode thyristor 7, main heating group 4, auxiliary heating group 9 and thermocouple 6, burner on light 8 is connected in parallel on auxiliary heating group 9 in addition, bidirectional triode thyristor 7 is serially connected in the ac circuit at auxiliary heating group 9 place for controlling the duty of 9 auxiliary heating groups 9, in work, the temperature that thermocouple 6 records can clearly be presented on the display screen on temperature control unit 10, in addition, for improving the supply socket 1 that security of the present utility model is also connected with switch 2 and has insurance on temperature control unit 10, temperature switch 3 is in series with between this supply socket 1 and positive electrode of temperature control unit 10.
In actual use, main heating group 4 is different with the heating power of auxiliary heating group 9, auxiliary heating group 9 adopts PTC element, this is because ptc material has positive temperature coefficient, heating power and temperature raises the also corresponding increase of its resistance, so the electric current passed through reduces, caloric value reduces, be easy to A.T.C, based on above-mentioned design, principle of the present utility model is: after energising, bidirectional triode thyristor 7 is triggered conducting, power supply indicator 5 and burner on light 8 are lit, main heating group 4 and auxiliary heating group 9 work simultaneously and are rapidly heated, after reaching uniform temperature (can according to actual conditions free setting), the switch opens of connecting with main heating group 4, thus the loop at main heating group 4 place is closed, main heating group 4 stops heating, only deposit auxiliary heating group 9 to continue to be heated to preset temperature, thus waste heat and thermal inertia can be reduced, to reduce the impact of hot overshoot.
