Description
Technical field
The utility model relates to thermostat, and particularly a kind of home electrical heater is with the disconnecting apparatus of toppling over of adjustable thermostat.
Background technology
It is slow-motion temperature control (K: bimetallic thermostat that the action form of adjustable thermostat in the market is KMT; M: responsiveness is a slow motion; T: adjustable thermostat), some product is also subsidiary topples over break function, but the slow motion temperature control can only be used in the low-voltage region of 100～130V, and it is when being used in 200～250V high voltage district, and the arcing situation is serious during action, easily causes use dangerous.
The purpose of this utility model is to provide a kind of adjustable thermostat, has the break function of toppling over, and can be in high voltage district operate as normal.
Summary of the invention
For achieving the above object, the utility model has adopted following technical scheme: the utility model is made up of bimetal leaf, the reed that drives the contact, band fixed contact reed and temperature-adjusting device etc., reed lower end position vertical hanging one weight of band fixed contact, described weight connect one can stir the plectrum that drives the contact reed.
Extend a foil on the reed of drive described in the utility model contact, a salient point is set on the foil.Described salient point is placed on the same side of moving contact, and is close proximity to the upper end of the plectrum of weight connection.Described plectrum lower end is hook solid, and the weight intermediate groove of Cylinder is placed on the plectrum crotch.Described plectrum has an aperture in the middle of the upper end, and aperture is connected plectrum on the sheet metal of band fixed contact reed extension downwards by rivet.There is the spacing double wedge of a restriction weight oscillator arc aperture lower end on the described plectrum.
The porcelain rod that is connected two ends band point between the one end aperture of drive described in the utility model contact reed and bimetal leaf, the other end that drives contact reed, bimetal leaf and drive the contact reed connects the insulation porcelain ring.
Described in the utility model with drive the contact reed against temperature-adjusting device form by porcelain rod and thermoregulation knob axle etc., the excellent and thermoregulation knob axle of porcelain is arranged on the top board.The suspension reed of the porcelain rod that is advanced by the thermoregulation knob axle in the middle of the long shell fragment, the suspension reed in the middle of the long shell fragment is abutted against the middle arc spring leaf of drive contact reed again.Described top board is connected with long shell fragment by the porcelain ring.
Advantages such as the utility model compared with prior art has topples over quick disconnection, safe and reliable.

Embodiment
Below in conjunction with drawings and Examples utility model is described in further details:
Fig. 1 to Fig. 4 shows a preferred embodiment of the present utility model, mainly is used in home electrical heater, as electric heating appliances such as filling type electric heater, Hot-air fans.The utility model is made up of reed 3 that is installed in the bimetal leaf 1 on the rivet 7 that is with porcelain logical 70, the reed 2 that drives contact 21, band fixed contact 31 and temperature-adjusting device 4 etc.Separate by insulation porcelain ring 72 between bimetal leaf 1, reed 3, reed 2 and the temperature-adjusting device 4.Band fixed contact reed 3 lower end position vertical hangings one weight 5, weight 5 connects one can stir the plectrum 6 that drives contact reed 2.
Drive and extend a foil 270 on the contact reed 2 downwards, one salient point 272 is set on the foil 270, salient point 272 is placed on the same side of moving contact 21, and be close proximity to the upper end of the plectrum 6 that weight 5 connects, when plectrum 6 swings, can promote salient point 272, contact 21 is separated with contact 31.Plectrum 6 lower ends are hook solid, weight 5 intermediate groove 51 of Cylinder are placed on plectrum 6 crotches, one aperture 61 is arranged in the middle of plectrum 6 upper ends, aperture 61 is connected plectrum 6 on the sheet metal 33 of band fixed contact reed 3 extensions downwards by rivet 63, and there is the spacing double wedge 65 of a restriction weight 5 oscillator arcs aperture 61 lower ends on the plectrum 6.Drive the porcelain rod 74 that is connected two ends band point between the end aperture of contact reed 2 and bimetal leaf 1.
With drive contact reed 2 against temperature-adjusting device 4 form by porcelain rod 76 and thermoregulation knob axle 43 etc., porcelain rod 76 and thermoregulation knob axle 43 are installed on the top board 45 by copper seat 47.The porcelain rod 74 that is advanced by thermoregulation knob axle 43 is against the suspension reed 25 of long shell fragment 23 centres that drive contact reed 2, suspension reed 25 in the middle of the long shell fragment 23 is abutted against the arc spring leaf 27 in the middle of the drive contact reed 2 again, and top board 45 is connected with long shell fragment 27 by porcelain ring 72.
The utility model rotates earlier inwardly the suspension reeds 25 that thermoregulation knob axle 43 (design temperatures) drive in the middle of the long shell fragment 23 and moves inward in use, hangs reed 25 drive reeds 2 moving contact 21 is communicated with fixed contact 31, and electric heating appliance begins heat temperature raising.Thermal sensitive piece 1 is along with the rising of temperature is outwardly-bent gradually, and it is outwards mobile to drive shell fragment 2 by porcelain rod 74.When temperature rose to design temperature, the amplitude of thermal sensitive piece 1 bending made the moving contact 21 that drives on the shell fragment 2 separate with fixed contact 31, thereby stopped heating.When the utility model was in normal operating conditions, the top that connects the plectrum 6 of weight 5 was horizontal, plectrum 6 with drive on the reed 2 of contact salient point 272 near, but do not produce active force.And when abnormal conditions such as electric heating appliance appearance inclination, plectrum 6 meetings swing under the effect of the gravity of weight 5, make the top of plectrum 6 occur tilting, two jiaos of ends of plectrum 6 push salient point 272 laterally, the moving contact 21 of shell fragment 2 is separated with moving contact 31 and cut off the load of electric heater, thereby guaranteed the safe in utilization of electric heating appliance.
