Description
Technical field
This utility model relates to a kind of overheat protector temperature sensitive control device, is specifically related to a kind of energy temperature sensitive controller for cut-off automatic recovery.
Background technology
In order to protect household electrical appliance, prevent household electrical appliance from damaging because components and parts are overheated in using, a temp sensing controller is often installed in household electrical appliance.Along with popularizing of household electrical appliance, temp sensing controller is in household electrical appliance already, especially in small household appliances, such as the most frequently used mechanical temperature-control and electric actuator parts such as water dispenser, water heater, small power electric heaters.And existing overheat protector temp sensing controller is the most all arranged in electric equipment; must cut off the electricity supply during reset; and use hand-reset form, i.e. open household appliances shell hands and make the contact in temp sensing controller contact by SR could to reset.So general layman just cannot operate, and Xu Song specialized maintenance department goes to repair, very inconvenient, practical.Power-off restoration temperature controller heater element on existing market is PTC, easily causes the decay of caloric value, can reset under special circumstances in the case of being electrified for a long time.
Summary of the invention
Goal of the invention of the present utility model is: have to the inconvenience of hand-reset and PTC instability under being electrified for a long time in order to solve existing temp sensing controller, this utility model provides a kind of temperature sensitive controller for cut-off automatic recovery, this temperature sensitive controller for cut-off automatic recovery simple in construction, easily operates.Only need to disconnect corresponding power supply a little while, temp sensing controller just can be automatically obtained reset and heating is stable.
The technical solution adopted in the utility model is such that a kind of temperature sensitive controller for cut-off automatic recovery, it is characterized in that: include insulation crust, fixed component, push rod, bimetal leaf, first assembly, second assembly, aluminum lid, heater element and bonnet, described first assembly and described second attached components are touched and are fixedly mounted in insulation crust by fixed component, described heater element is connected with fixed component by conductive wafer, it is provided with centre bore in described insulation crust, a push rod is placed in described centre bore, one end contacts with bimetal leaf, the other end and the first component touch being arranged in housing.
In order to solve the heater element of original PTC material, easily causing the decay of caloric value, the problem that will not reset under special circumstances in the case of being electrified for a long time, described heater element is the glaze resistance alloy sintered on ceramic substrate.
Further, for simple in construction, convenient installation, described first assembly includes movable contact, movable contact spring and lug plate, described movable contact, movable contact spring and lug plate are fixing by riveting, described second assembly includes stationary contact, quiet lug plate, described stationary contact and described quiet lug plate are fixing by riveting, and described quiet lug plate contacts with movable contact.
For effective fixing and connection heater element in the confined space, fixed component selects rivet.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are: this temperature sensitive controller for cut-off automatic recovery simple in construction, easily operate, and heater element uses the glaze resistance alloy sintered on ceramic substrate, generate heat more stable, as long as deenergization can automatically reset after excess temperature tripping, it is not necessary to manual operation, there is the plurality of advantages such as stability is high, safety is high, service life is high, and very convenient to use, and cost is relatively low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
Labelling in figure: 1 is insulation crust, 2 is rivet, and 3 is push rod, and 4 is bimetal leaf, and 5 is aluminium lid, and 6 is heater element, and 7 is bonnet, and 8 is conductive wafer, and 9 is movable contact, and 10 is movable contact spring, and 11 is lug plate, and 12 is stationary contact, and 13 is quiet lug plate.
Detailed description of the invention
Below in conjunction with the accompanying drawings, this utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
Such as Fig. 1, shown in Fig. 2, a kind of temperature sensitive controller for cut-off automatic recovery, including insulation crust 1, fixed component, push rod 3, bimetal leaf 4, first assembly, second assembly, aluminium lid 5, heater element 6 and bonnet 7, first assembly and described second attached components are touched and are fixedly mounted in insulation crust 1 by fixed component, described heater element 6 is connected with fixed component by conductive wafer 8, it is provided with centre bore in described insulation crust 1, a push rod 3 is placed in described centre bore, one end contacts with bimetal leaf 4, the other end and the first component touch being arranged in housing.Heater element 6 selects the glaze resistance alloy sintered on ceramic substrate, first assembly includes movable contact 9, movable contact spring 10 and lug plate 11, movable contact 9, movable contact spring 10 and lug plate 11 are fixing by riveting, second assembly includes stationary contact 12, quiet lug plate 13, described stationary contact 12 and described quiet lug plate 13 are fixing by riveting, and described quiet lug plate 13 contacts with movable contact 9.Fixed component selects rivet 2.
During installation, first by movable contact 9, movable contact spring 10 constitutes the first assembly with lug plate 11 by riveting is fixing, stationary contact 12 constitutes the second assembly with quiet lug plate 13 by riveting is fixing, , heater element 6 selects the glaze resistance alloy sintered on ceramic substrate to put into insulation crust 1, rivet 2 respectively penetrates conductive wafer 8 and penetrates in shell, the first assembly on the other end of rivet 2 overlaps respectively, second assembly is fixed by riveting, push rod 3 is put in shell centre bore, bimetal leaf 4 is put on upper edge, buckle aluminium lid 5 spinning to fix, at other end rivet 2, on point, glue adds that bonnet 7 is by whole controller good seal.
When power-off restoration temp sensing controller temperature be increased to bimetal leaf 4 beat critical time, bimetal leaf 4 kick, just push rod 3 is promoted, thus promote movable contact spring 10 to make movable contact 9 disconnect with stationary contact 12, the least electric current is just through heater element, heater element 6 generates heat, and makes bimetal leaf 4 maintain tripping state, even if two contacts maintain off-state.Working as deenergization, temperature declines, and bimetal leaf 4 kick becomes initial condition, drives push rod 3 so that movable contact 9 contacts with stationary contact 12, i.e. resets, and circuit ON plugs in the most again, and electric equipment can normally use.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
