Abstract
The utility model discloses a plug-in temperature regulator which is matched with an electric heating appliance. The plug-in temperature regulator is mainly composed of a temperature sensitive probe, a thermoregulator, driving reeds, conductive inserting reeds and a power supply line, wherein, the temperature of the utility model can be higher than the maximum operation temperature of the thermoregulator. The utility model has the advantages of simple structure, good safety, superthermal protection to electric heating appliances, circuit break protection under abnormal conditions, etc., suitable to be an ideal plug-in temperature regulator.
Description
The utility model relates to a kind of temperature regulator, relates in particular to a kind of and the matching used plug-in type temperature regulator of temperature-adjusting type electric heating appliance.
Common in the market plug-in type temperature regulator is mainly inserted spring, thermosistor knob and shell by temperature-sensing probe, thermosistor, pilot lamp parts, conduction and is formed.Its principle of work is: open close by the contact on the temperature-sensing probe expanded by heating drivening rod control thermosistor spring leaf.Thereby reach the temperature control purpose.But after this plug-in type temperature regulator length service time, its contact meeting oxidation or sintering, thus cause thermosistor out of control, damage supporting electric heating appliance, serious also can cause fire.Also have in the plug-in type temperature regulator and installed thermal cut-off additional, in order to play the second protection effect.But the hot melt fracture of wire in the thermal cut-off is subjected to the influence of voltage fluctuation and rush of current easily, and is very unstable.
The purpose of this utility model is to provide the plug-in type temperature regulator that a kind of temperature-sensitive condition is good, have superthermal protection and abnomal condition break protecting.
The utility model is a kind of plug-in type temperature regulator, mainly by temperature-sensing probe, thermosistor, the transmission reed, conduction inserts spring and power lead is formed, between slotting spring of conduction and power lead, temperature limiter is housed, temperature limiter is by set screw, the temperature limiter knob, big reed and less reed are formed, and have a contact right on big reed and the less reed correspondence position, have aperture on the temperature limiter knob, the big reed of temperature limiter is corresponding with the top porcelain on the transmission reed, and spacing is greater than the big reed of thermosistor and the distance between the porcelain of top.
The utility model adopts said structure, guaranteed that not only the temperature-sensitive condition is good, and out of control at thermosistor, during the temperature superelevation, temperature limiter can be cut off the electricity supply automatically, thereby protect and the matching used electric heating appliance of temperature regulator, really plays the second protection effect.
Below in conjunction with the drawings and Examples formula the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model plug-in type temperature regulator.
Fig. 2 is a kind of structural representation of temperature limiter of the present utility model.
Fig. 3 is the another kind of structural representation of temperature limiter of the present utility model.
Fig. 4 is the wiring diagram of the utility model plug-in type temperature regulator.
The plug-in type temperature regulator is inserted spring 4 and 5, pilot lamp parts etc. by temperature-sensing probe 1, thermosistor 2, temperature limiter 3, conduction and is formed, the pilot lamp parts comprise pilot lamp 8 and ensconce the interior current-limiting resistance 9 of lead that this plug-in type temperature regulator is by connecting above-mentioned each device by wiring diagram shown in Figure 4.Temperature-sensing probe 1 among Fig. 1 is a kind of garden shape pencil shape bulged tube, be welded on below it on the support 20, above with transmission reed 10 welding of centre band concave indentation, be connected by connecting rod 11 between the projecting point of the concave shape breach of and transmission reed 10 inner at temperature-sensing probe 1.Respectively there are two top porcelain 12 and 13 in B side on two jiaos of transmission reed 10.The less reed 15 of thermosistor 2 connects power lead 6, and big reed 14 is inserted spring 5 by lead and conduction and is connected, and a contact is arranged to 16 on the two reed correspondence positions.The less reed 18 of temperature limiter 3 connects power lead 7, and big reed 17 is inserted spring 4 by lead with another conduction and is connected.Temperature limiter 3 is fixed on the support 20 side by side with thermosistor 2, the big reed 17 of temperature limiter 3 and the reed 14 greatly of thermosistor respectively with transmission reed 10 on top porcelain 12 and top porcelain 13 corresponding.From Fig. 2, temperature limiter 3 is made up of the set screw 23 that runs through support 20 and big reed 17 and less reed 18, the lifting that comes regulating and controlling screw 23 by the garden shape aperture 22 on the temperature limiter knob 21.Thereby drive reed 17 and reed 18 actions, regulate the longer reed 17 of temperature limiter 2 and the distance between the top porcelain 13 on the transmission reed 10, can set the outage temperature of temperature limiter 3.The outage temperature of temperature limiter 3 is generally preestablished and is higher than the maximum operation (service) temperature of thermosistor 2 by manufacturer, this point realizes greater than the big reed 14 of thermosistor 2 and the distance between the top porcelain 12 by big reed 17 and the distance between the top porcelain 13 of setting temperature limiter 3.A contact is arranged to 19 on big reed 17 and less reed 18 correspondence positions.
During use, temperature regulator inserts electric heating appliance, and after the energising, pilot lamp 8 is bright, expression energising heating; When reaching temperature required, temperature-sensing probe 1 expanded by heating drives transmission reed 10 by connecting rod 11, and the big reed 14 of top porcelain 12 compressing thermosistors on the transmission reed 10 makes the contact on big reed 16 correspondence positions disconnect 16.At this moment, pilot lamp 8 extinguishes and represents outage insulation; Temperature required when following when being cooled to, the contact is connected again 16, continues heating, so repeatedly circulation.After 2 service times of thermosistor were long, the contact can oxidation or sintering to 16, caused thermosistor 2 short circuits and out of control.Because temperature limiter 3 replaces thermosistor 2 work, pilot lamp 8 is still bright, continue the energising heating, when reaching the outage temperature of temperature limiter 3, temperature-sensing probe 1 expanded by heating drives by connecting rod 11 and passes a reed 10, top porcelain 13 on the transmission reed 10 is oppressed the big reed 17 of temperature limiters 3, and the contact on big reed 17 and less reed 18 correspondence positions is disconnected 19, cuts off the electricity supply.At this moment, pilot lamp 8 extinguishes, and when the outage temperature that is cooled to temperature limiter 3 was following, the contact was to 19 connection/continuation heating again, and pilot lamp 8 is bright again, and so forth.Finally reach the warm purpose of limit.
Certainly; above-mentioned temperature limiter 3 can also adopt other structures, is the another kind of structure of temperature limiter as shown in Figure 3, and the reed shape of this kind structure and the reed shape of thermosistor are basic identical; also can do some other conversion, this this conversion all drops in the utility model protection domain.
