Description
Technical field
The invention belongs to electrical equipment temperature control technology field, be related specifically to the Kick type temperature controller of the overheated safeguard protection of home electrical heater.
Background technology
At present, power-off automatically resets Kick type temperature controller than traditional hand-reset Kick type temperature controller complex structure, install also inconvenient, therefore, price is higher, a kind of power-off Automatic-reset bimetallic temperature controller as disclosure of the invention that application number is 201220420573.6, this temperature controller comprises pedestal, be installed on first in pedestal, two contact chips, be installed on first of base bottom, two lug plates and the inlay card upper cover on pedestal and the bimetal leaf be installed in upper cover, wherein, movable contact spring on second contact chip and the first contact chip are formed and are electrically connected, form the first path, pedestal is provided with the aluminium lid for bimetal leaf and upper cover being packaged in pedestal, the insulation of also installing in pedestal performs bar one end and movable contact spring is conflicted, and the other end is conflicted through upper cover and bimetal leaf, the bottom of upper cover is provided with conducting strip and the thick film between conducting strip, and this conducting strip and thick film are electrically connected, and conducting strip is electrically connected respectively by short spring and long spring and first and second lug plate, forms alternate path, this alternate path connects with the first path in parallel.Because said temperature controller needs installation two little springs, therefore its assembling and quality control all more difficult.
Summary of the invention
The object of the invention is to propose that a kind of structure is simple, easy to assembly, the Kick type temperature controller of the overheated safeguard protection of service-strong, this kind of Kick type temperature controller is after overtemperature protection, and having to pass through power-off could reset work, has good fail safe.
The Kick type temperature controller of overheated safeguard protection of the present invention comprises housing, aluminium lid, leading truck, bimetal leaf, actuating strut, fixed contact assembly, moving contact assembly and two binding posts; Described fixed contact assembly, moving contact assembly are pressed in both sides inside and outside housing bottom surface respectively by rivet with corresponding binding post; Key is to be provided with one deck resistive film between the bottom surface of described housing and binding post, and described two binding posts are electrically connected by described resistive film.
The operation principle of above-mentioned Kick type temperature controller is as follows:
Its internal structure is the same with common Kick type temperature controller with operation principle, and its difference is that two binding posts are electrically connected by the resistive film of the bottom surface of housing.During work, the closing of contact of Kick type temperature controller, between two binding posts, resistance is zero, when temperature raises, when bimetal leaf makes Kick type temperature controller contact disconnect, because the resistance of resistive film is far longer than load resistance, voltage between two binding posts equals the voltage of incoming call power supply substantially, electric current passes through binding post, resistive film flows to another binding post and flows through load again and form loop, heat and heated shell can be produced during resistive film energising, as long as the resistance of appropriate design resistive film, the temperature of bimetal leaf just can be made to be kept above reset temperature, therefore, only otherwise cut off the electricity supply, two contacts will disconnect always.Resistance due to resistive film is general all more than thousands of Europe, and the electric current flowing through load is little, therefore applies very reliable in overtemperature protection.
After cutting off the electricity supply, resistive film stops heating because of not having electric current to flow through, and automatically reset after the bimetal leaf of Kick type temperature controller is cooled to reset temperature, two contacts close again, does not so just need manual reset as manual thermostat.
Further, described housing is that pottery is made, and resistive film covers a layer electrode membrane in the position contacted with binding post, and described resistive film, electrode film burn till through high temperature together with housing.Electrode film makes contact resistance between binding post and resistive film very little, thus ensures to keep good electrical connection between binding post and resistive film.Concrete technology is as follows: ceramic shell is by silk screen printing resistive film, electrode film, and then high temperature burns till, and electrode film covers on resistive film, and electrode film is silver slurry, can make resistance stabilization by high temperature sintering.
The above-mentioned rivet force of rivet that only utilizes depends on the size of rivet force in the mode compressing binding post and resistive film (electrode film) in reliability, reliability is slightly low, for addressing this problem, the present invention proposes following structure: described binding post is embedded in the groove that housing bottom surface is provided with, described binding post is pressed with shell fragment by described rivet, and the end of described shell fragment is pressed on described electrode film.Shell fragment remains the contact with binding post, electrode film under himself elastic force effect, and shell fragment inherently good conductor, therefore can ensure that the electrical connection between binding post and electrode film, resistive film is reliable.
Further, be provided with mica sheet between described shell fragment and electrode film, resistive film, a part for described shell fragment end is pressed on described mica sheet.Mica sheet has good insulating properties, thermal insulation, therefore can reduce resistive film heat and outwards distribute, and improve fail safe.
Further, for ensureing insulation and improving heat-insulating property, and then reduce the power requirement of resistive film, this Kick type temperature controller also comprises the fluid sealant bottom covering shell.
Compared to the Kick type temperature controller in background technology; the position of resistive film has been arranged on the bottom surface of housing by the Kick type temperature controller of overheated safeguard protection of the present invention; and utilize rivet resistive film, electrode film and binding post to be compressed; eliminate the mounting structure of spring compression; therefore assemble more simple, quality is also more reliable.
