Abstract
The utility model relates to a wholly enclosed bimetal temperature limiter, having a housing (1), a bimetal sheet (2), a cover (3), a fixing sheet combination (5), a moving sheet combination (6) and a base (7). The moving sheet combination (6) and the fixing sheet combination (5) are positioned in the base (7); a ceramic bar (4) passes through a hole in the cover (3); the bimetal sheet (2) is placed on a concave part step on the cover (3); the lower end of the ceramic bar (4) can contact the moving sheet combination (6), and the upper end can contact the bimetal sheet (2); a periphery of the lower part of the housing (1) is sealed on the upper end of the base (7) and under the step. The utility model has the advantages of simple structure, sensitive response, shock resistance, wet resistance, etc., can be used for domestic appliance products, and has temperature limiting and heat protective functions.
Description
The utility model relates to a kind of temperature limiter.
Temperature limiter is widely used on household electrical appliance and the electric heating appliance, and Chinese patent once disclosed " hand-reset one way quick-action temperature limiter " (ZL86103184), needs manually could restore; " clapper-type magnetic temperature limiter " (ZL86205922) (ZL87202571) do not adopt bimetal leaf with " temperature limiter resets ", and being quick on the draw property is not strong; " temperature limiter " (94236701) are made up of ceramic package, loam cake, lug plate, moving plate combination, stator combination and rivet etc., it is characterized in that the bimetal leaf structure that adopts, and its whole moving plate is not more than or equal to 90 ° bending.The temperature limiter of these structures exist anti-ly shake, the defective of moisture-resistance difference.
In order to overcome the defective that above-mentioned technology exists, the purpose of this utility model is to provide a kind of totally-enclosed bimetal leaf temperature limiter, and it is simple in structure, be quick on the draw, anti-ly shake, humidity.
For achieving the above object, the solution that the utility model is taked is: a kind of totally-enclosed bimetal leaf temperature limiter, have shell, bimetal leaf, lid, stator combination, moving plate combination, seat, mid-moving plate combination of seat and stator combination, the porcelain rod is by the hole in the lid, bimetal leaf is placed on and covers on the recess step, and porcelain rod lower end can contact with the moving plate combination, upper end can contact with bimetal leaf, below the upper end step that outer casing underpart one all press seals are present.
Operation principle of the present utility model is: the controlled device heat temperature raising, shell is heated to conduct heat and gives bimetal leaf, and the energy delivery that bi-metal plate deformed produces is given the porcelain rod, when temperature rises to institute's controlling temperature, the energy of its generation is enough to make movable contact spring to leave fixed touching plate, cuts off heater power source; When temperature descended, bimetal leaf restored, and movable contact spring and fixed touching plate are closed again.So played the gentle heat protective effect of automatic limit; because in the utility model; bimetal leaf, porcelain rod, lid, movable contact spring and fixed touching plate all are in sealing state; so characteristics of tool humidity; and shell and seat be press seal together again in the top under the protuberance (step) tightly; and other part all is in sealing state, therefore has very high vibration-resistant property.The utility model can be widely used in household electrical appliance.
The utility model will be further described below in conjunction with accompanying drawing.
Accompanying drawing is a front portion of the present utility model cutaway view.
As shown in the figure, present (7) mid-moving plate combinations (6) and stator combination (5), moving plate combination (6) and stator combination (5) are in normally off, male blade is inserted in and stretches out outside the seat (7) in the seat (7) in male blade in the moving plate combination (6) and the stator combination (5), and seal with high temperature insulation glue, seat (7) is gone up and is placed lid (3), on the lid (3) recess is arranged, step is arranged in the recess, through hole in the lid (3), porcelain rod (4) is by lid (3) mesopore, bimetal leaf (2) is placed on lid (3) the upper recess step, porcelain rod (4) lower end can make up (6) and contact with moving plate, upper end can contact with sheet metal (2), below the step of the upper end of shell (1) bottom one all press seals present (7).In the utility model, seat (7) and lid (3) preferably adopt ceramic material to make, and shell (1) adopts the good corrosion resistant sheet metal of heat conductivility to make.
Claims (2)
1, a kind of totally-enclosed bimetal leaf temperature limiter, have shell (1), bimetal leaf (2), lid (3), stator combination (5), moving plate combination (6), seat (7), it is characterized in that: mid-moving plate combination of seat (7) (6) and stator combination (5), porcelain rod (4) is by lid (3) mesopore, bimetal leaf (2) is placed on lid (3) the upper recess step, porcelain rod (4) lower end can make up that (6) contact, upper end can contact with bimetal leaf (2) with moving plate, below the upper end step of shell (1) bottom one all press seals present (7).
2, a kind of totally-enclosed bimetal leaf temperature limiter according to claim 1 is characterized in that: seat (7) and lid (3) all adopt ceramic material to make.
