Abstract
The utility model relates to a non-resettable disc bimetal thermoregulator, which increases a passive elastic disc in the existing thermoregulator, and the existing thermoregulator is composed of a cover, a moving contact, a fixed contact, a push rod, a base and a bimetal disc; when the temperature sensitivity of the thermoregulator reaches the set temperature, the bimetal disc turns over, and the moving contact is pushed, and simultaneously the passive elastic disc is driven to turn over; when the temperature is dropped, the bimetal is recovered, and the moving and the fixed contacts are still separated because of the support of the passive elastic disc. The non-resettable disc bimetal thermoregulator can be reset as long as the push rod is pressed by external force; thus, the temperature controlling and external force resetting purposes are reached. The design is widely used for electric heating appliances which have to use the non-resettable disc bimetal thermoregulator.
Description
The utility model relates to a kind of temperature controller tool, especially the electric heating temperature controller of bimetallic strip control.
At present, the structure of general butterfly shaped dual metal sheet temperature controller is to be combined by lid, pedestal, movable contact spring, static contact and butterfly shaped dual metal sheet.When the thermostat temperature-sensitive reached design temperature, the butterfly shaped dual metal sheet upset by catch bar, separated dynamic and static contact and reaches the purpose of cutting off heating power supply; Heat source temperature reduces, and butterfly shaped dual metal sheet restores, power connection.This automatically reset temperature controller can not be fit to the non-normal working requirement of GB4706.1-92 " safety general of family expenses and similar applications electrical equipment requires ".
The purpose of this utility model provides the temperature controller that a kind of energy is suitable for the requirement of electric heater non-normal working.
The utility model is its task that realizes like this: the pedestal that the heatproof insulating material system of chute is arranged in it comprises, be placed in the crown cap of its end face, in pedestal, can freely overturn and be close to the bimetal disk of lid, the porose passive spring disk in center in place in the draw-in groove in the middle of base internal wall, there is draw-in groove the middle and lower part and penetrates screens top, passive spring disk center has the both wings of perforation to have sliding tenon to be positioned the catch bar of the insulating temperature resistant meterial system of pedestal chute, be fixed in pedestal top on one side on the ear and riveting the conduction static contact of silver contact is arranged, be fixed on the another side ear of pedestal top and overpunching that riveting has the elastic conduction movable contact spring of silver contact to pass catch bar, moving contact and stationary contact join.It is characterized in that: because bimetal disk is close to crown cap, temperature-sensitive fast and before it reaches the equilibrium point of design temperature the temperature-sensitive face be one and expand maximum process gradually to, so its response speed is similar dish-shaped temperature controller prostatitis; Its feature also is: bimetal disk reaches and will promote catch bar after the design temperature upset and make the passive spring disk upset of screens on it, and the while catch bar is also pushed movable contact spring open, and dynamic and static contact is disengaged; Its feature also is: when thermal source left or lowers the temperature the bimetal disk recovery, because the support of passive spring disk, dynamic and static contact still broke away from.Have only when external force be added under the catch bar by, just can make the passive spring disk of screens on it reply original state, and make the contact of dynamic and static contact again; Its feature also is: thermometal dish sheet temperature control action element separates from the flexible member passive spring disk that resets with restriction.
Owing to adopt above scheme, can make by the electric heater of butterfly shaped dual metal sheet temperature controller control and break away from automatically heating repeatedly.Control the heating that resets and add external force by needs.
Fig. 1 is utility model example 1 structural representation.
Fig. 2 is utility model example 2 structural representations.
Fig. 3 is utility model example 3 structural representations.
Its lower surface of pedestal (6) of non-automatic-reset butterfly shaped dual metal sheet temperature controller is fastened with the crown cap (1) of temperature-sensitive, inside be close to lid be equipped with can freely overturn the dish-shaped sheet (7) of thermometal, the draw-in groove passive spring disk (2) that center pit is arranged in place in the middle of its inwall, there is draw-in groove the middle and lower part and penetrates passive spring disk center pit screens, there is perforation the middle and upper part, two wing slip tenons are positioned the catch bar (4) of pedestal chute, pedestal top is fixed with on one side the conduction static contact (5) of band silver contact on the ear, is fixed with the band silver contact on another top ear of pedestal, and pass the catch bar overpunching, make, stationary contact joins, elastic conduction movable contact spring (3).
According to producing and service condition, the lid of non-automatic-reset butterfly shaped dual metal sheet temperature controller can be perforate, and thermal source stretches into the lid life size that is removed, and its function is constant, and because directly its effect of conduction will be better.
According to producing and service condition, the dynamic and static contact of non-automatic-reset dish bimetallic temperature controller can be contained in the pedestal, by conductive fastener connector is drawn, and its function is constant, and can prevent the pollution of dynamic and static contact.
With Fig. 1 is that example is used elaboration: when the heat of thermal source reaches thermometal dish sheet (7) by lid (1), force its deformation to be stretched to equilibrium point (design temperature) upset epirelief, moved dish-shaped sheet (2) upset of drive is also pushed movable contact spring (3) open simultaneously and is made dynamic and static contact separation; When thermal source is withdrawn or the thermometal dish sheet (7) of lowering the temperature resets, but because the support of passive spring disk, still separate the sound contact; Have only when pressed by external force catch bar (4), the passive spring disk of screens on it resetted, rubber-like conduction movable contact spring (3) is bullet down, and dynamic and static contact resumes contacts, and resets.
With Fig. 2 is that example is set forth: stretch into lid (1) removed life size as thermal source, thermal source directly contacts with thermometal dish sheet (7), and then heat-transfer effect is better.
With Fig. 3 is that example is set forth: be contained in the pedestal (6) as elastic conduction movable contact spring (3) and conduction static contact (5), and draw with conductive fastener, then can significantly reduce the pollution of dynamic and static contact, function still.
Claims (3)
1. non-automatic-reset butterfly shaped dual metal sheet temperature controller, it comprises pedestal, its lower surface is fixed with crown cap, inside is close to lid butterfly shaped dual metal sheet is housed, pedestal top is fixed with the static contact of being with silver contact on the ear on one side, be fixed with the movable contact spring of band silver contact on the another side ear, moving, stationary contact can join, it is characterized in that: the base internal wall draw-in groove is in place the quilt of the center hole clipping dish-shaped sheet of moving, that there is a draw-in groove middle and lower part and penetrate the hole clipping screens of passive spring disk center, there is perforation the middle and upper part, two wing slip tenons are positioned the catch bar of pedestal sidewall chute, and movable contact spring passes wherein overpunching and static contact joins.
