Description
Technical field
The present invention relates to domain of control temperature more particularly to a kind of double-metal sheet type temperature controls with overtemperature protection system
Device.
Background technique
Temperature controller refers to the temperature change according to working environment, physical deformation occurs in switch internal, to generate certain
Special effects generate a series of Automatic Control Components for being switched on or off movement, are also temperature detect switch (TDS), temperature protector, temperature
Spend controller, abbreviation temperature controller.Or temperature is passed to by temperature controller by temperature protector, temperature controller issues switch
Order, to control the operation of equipment to reach ideal temperature and energy-saving effect, application range is very extensive, according to difference
The temperature controller of type is applied in numerous products such as household electrical appliances, motor, refrigeration or heating.
Currently, general bimetal strip thermostat includes adjusting shaft, insulation assembly, double gold including mounting bracket, temperature
Belong to piece, elastic plate mechanism and porcelain knob.When temperature controller temperature-sensitive reaches preset temperature, bimetal leaf is heated to be bent to porcelain knob, passes through porcelain
The moving contact piece of elastic plate mechanism is played in capital, makes dynamic and static contact point separately achieve the purpose that cut off thermoelectric generator, heat source temperature reduces
To the recovery temperature of setting, bimetal leaf automatically resets, and the dynamic and static contact point of elastic plate mechanism is connected to again, and power supply is connected.But
The product of this structure fails after using more than projected life, can not disconnect after leaking copper bottom such as contact, bimetallic temperature drift
More than initial range, bimetal leaf is indeformable, is unable to control cutting circuit, and the circuit device controlled is overheating always, exists very
Big security risk, therefore in addition the bimetal strip thermostat of traditional structure is generally required using chemical fuse, production cost
It is high.
Therefore, how existing bimetal chip thermostat is improved, so that it is overcome drawbacks described above is this field skill
An art personnel problem urgently to be resolved.
Summary of the invention
In view of the above-mentioned state of the art, a kind of with overheat guarantor technical problem to be solved by the present invention lies in providing
The bimetal chip thermostat of protection unit eliminates porcelain bar, increases supporting lug, when accelerating the response of overtemperature protection system
Between, it is combined into one by temperature controller and insurance, reduces production cost, and easy for installation, it is reliable and stable under hot environment.
The technical scheme of the invention to solve the technical problem is:
A kind of bimetal chip thermostat with overtemperature protection system, including mounting bracket, temperature adjust shaft, insulation
Component, bimetal leaf, elastic plate mechanism and porcelain knob, insulation assembly and temperature adjust shaft and are installed in mounting bracket, elastic slice machine
Structure is mounted on insulation assembly, and porcelain knob both ends are separately connected elastic plate mechanism and bimetal leaf, further includes being mounted on insulation assembly
Overtemperature protection system, overtemperature protection system is arranged in series with elastic plate mechanism, the heated kick operating temperature of overtemperature protection system
Not less than the heated kick operating temperature of elastic plate mechanism, overtemperature protection system includes the first movement elastic slice, static contact piece, kick pair
Gold plaque is provided with the first movement contact and support convex on the first movement elastic slice, and static contact on piece is provided with and the first movement is touched
The first static contact point for matching of point, the double gold plaques of kick be located at the lower section of the first movement elastic slice and with its companys of offseting, kick is double golden
Piece is contacted with support convex.
Preferably, the first movement elastic slice is fixedly installed the bending part to match with the double gold plaques of kick.
Preferably, elastic plate mechanism include the spring leaf being arranged on insulation assembly and static contact on piece is set it is second quiet
Contact point is fixedly installed the second movement elastic slice on spring leaf, is provided on the second movement elastic slice and the second static contact point matches
The the second movement contact closed, the both ends of porcelain knob are separately connected bimetal leaf and spring leaf.
Preferably, the insulation resistance of insulation assembly is 100M Ohm.
The utility model has the advantages that
When bimetal leaf failure can not deform or elastic plate mechanism failure can not flick, overtemperature protection system temperature is after of continuing rising
The high double gold plaques movement kicks of the kick after reaching preset temperature, since the porcelain bar eliminated in existing overtemperature protection system is set
Meter, and the double gold plaques of kick are located at the lower section of the first movement elastic slice and contact with support convex, therefore the double gold plaques of kick are in its movement
The first movement elastic slice can be pushed directly on when kick, promote the first movement contact and the first static contact point quick separating, therefore shorten
The disengaging time of the two, accelerates the response time of overtemperature protection system, meanwhile, bending part can play the double gold plaques of kick solid
Fixed and stable effect, ensure that the first movement contact and the first static contact point quick separating, therefore overtemperature protection system is effective
Electric heater is protected, prevents electric heater from burning out and even causes fire, temperature controller and insurance are closed two by temperature controller provided by the invention
It is one, reduces the production cost of temperature controller, and easy for installation, it is reliable and stable under hot environment.
