Below in conjunction with accompanying drawing the utility model is described further.
Shown in Fig. 1-4, the temperature-sensitive housing of present embodiment is a circular metal housing 1, make by the metallic aluminium sheet stamping, and also can be other metal materials as required, as stainless steel, copper etc.For effective temperature-sensitive, the contact-making surface shape of temperature-sensitive housing also can be other shapes that match with the heating combined equipment surface configuration.
Bimetal leaf is a Kick type bimetal disk 2, and the temperature spot of its rotary movement is to preestablish according to the supporting safe temperature that heating combined equipment limited.Bimetal disk 2 is arranged on the annular tongue 1.1 of circular metal housing inside bottom surface, so that leave the space for the rotary movement at bimetal disk 2 middle parts.
The insulating base housing is circular plastic casing 5, ceramics seat is circular stair-stepping ceramics seat 3, its adapting device is provided with between ceramics seat 3 and circular metal housing 1 bottom surface and makes bimetal disk 2 carry out the cavity of rotary movement with design temperature in circular metal housing 1.The interlock insulating part is columniform ceramic push rod 4, and the one end is against bimetal disk 2 surfaces, and the other end stretches out the centre bore 3.1 of ceramics seat 3.
Circular plastic casing 5 is divided into upper chamber and lower chambers, and its lower chambers is arranged on the described ceramics seat 3, is connected by staged interface 3.3 with ceramics seat 3.On the plastic casing 5 of circle, also be provided with the centre bore 5.1 that passes for ceramic push rod 4.The connecting through hole (not shown) of electrical connection module is set on the partition wall of upper chamber and lower chambers.
Electrical connection module comprises first binding post 6, second binding post 7, moving contact 8, decides contact 9 and moving contact spring sheet 10, and they are arranged in the upper chamber of plastic casing 5.Wherein the stiff end of first binding post 6 is fixedlyed connected with the bottom surface of plastic casing 5 upper chamber respectively by second tubular rivet 16 by the stiff end of first tubular rivet 15, second binding post 7.First tubular rivet 15, second tubular rivet 16 pass the connecting through hole that is arranged between upper chamber and the lower chambers respectively.The stiff end of moving contact reed 10 is fixedlyed connected with first binding post 6, the free end of moving contact reed 10 is provided with moving contact 8, be provided with and corresponding circular contact 10.1, the termination of ceramic push rod 4 at the middle part of moving contact reed 10, relative with moving contact 8 contact 9 of deciding be set in the termination portion of second binding post 7.
On plastic casing 5, capping is set, capping is circular plastic closure 17, location hole 17.1 and butt joint tooth 17.2 are set on plastic closure 17, on plastic casing 5, be provided with the location hole 17.1 of plastic closure 17 and dock tooth 17.2 corresponding alignment pin 5.2 and docking port 5.3, this fit system tightly is sealed on electrical connection module in the insulating base, only expose the terminals of first binding post 6 and the terminals of second binding post 7, not only connect firm and sealing better, can avoid dust, external environment conditions such as steam are to the temp-limiting thermostat inner body especially harmful effect of electrical connector.
The course of work of present embodiment is as follows:
The temperature-sensitive housing of temp-limiting thermostat is placed on the heating surface of heating combined equipment, when the working temperature of heating combined equipment is in limited range, bimetal disk 2 is recessed state, this moment moving contact 8 and decide contact 9 and be in closure state, electric current passes through moving contact reed 10, moving contact 8 and decides contact 9 to arrive second binding post 7 from first binding post 6, makes the electric heating element 18 of heating combined equipment be in the energising heated condition.
When surpassing limiting temperature owing to improper reason heating combined equipment, the temp-limiting thermostat is sensed the operating temperature that the temperature that contacts the temperature-sensitive surface of shell reaches setting, 2 winks of bimetal disk turn over promptly, become the epirelief state, promotion is against bimetal disk 2 lip-deep ceramic push rods 4 and moves upward, and the corresponding circular contact 10.1 of an end of pushing tow moving contact reed 10 middle parts and ceramic push rod 4 moves upward, and is in off-state thereby make moving contact 8 and decide contact 9.But this moment, electric current still arrived second binding post 7 from first binding post 6 by the first compression spring 13, PTC heater 11, conducting strip 12, the second compression spring 14, made PTC heater 11 still be in "on" position.At this moment PTC heater 11 forms with the electric heating element 18 of heating combined equipment and connects, referring to Fig. 5.Because the resistance of PTC heater 11 is thousands of ohms, the resistance that is higher than the electric heating element 18 of heating combined equipment far away, therefore power source voltage is fallen all at the two poles of the earth of PTC heater 11, and the electric heating element 18 of heating combined equipment is in stops heated condition, and PTC heater 11 persistent fevers.Because the heat of PTC heater 11 reaches bimetal disk 2 by ceramics seat 3, make it continue to keep the epirelief state, thereby make moving contact 8 and decide contact 9 and still be in off-state, even heating combined equipment cooling, but bimetal disk 2 can not replied, after the whole device outage of manual intervention, the 11 outage coolings of PTC heater, bimetal disk 2 just returns back to initial recessed state.
