Description
Technical field
The utility model relates to thermostat technical field, especially a kind of sensitive-type compression-type temperature controller, is applicable in refrigerator for controlling the compression-type temperature controller of refrigerant compressor break-make.
Background technology
Compression-type temperature controller is widely used in refrigerator refrigeration control.Existing compression-type temperature controller, primarily of shell, cover plate, camshaft, cam bit, Clip Reed, L shape master arm, extension spring, adjustment plate, push rod, touch spring, spring leaf, pin C, pin L, moving contact, fixed contact and bellows composition.Camshaft and cam bit by Clip Reed clamping on the cover board, become an entirety.One end of adjustment plate leans against in cam bit outer rim, and one end of extension spring is hung in the middle of adjustment plate by adjustment screw, and the other end hangs on L shape master arm; By adjusting the direction of camshaft, the position of adjustment plate can be changed, thus adjustment extension spring is to the pulling force of L shape master arm; Be provided with a through hole in dividing plate middle and upper part, push rod is through this through hole, and its two ends are connected with spring leaf, L shape master arm respectively; L shape master arm, under the acting in conjunction of bellows and extension spring, carries out reciprocating rotation, thus promotes push rod and carry out shift reciprocately; When falling at temperature, push rod moves to right, and when reaching critical break-off signal, push rod promotes spring leaf and produces kick, drives moving contact, fixed contact to throw off, circuit is disconnected, and temperature starts to rise; When temperature rises, push rod moves to left, and when reaching critical connection temperature, push rod drives spring leaf to produce kick, moving contact, fixed contact is bonded, makes circuit ON, and temperature starts to decline.The movement locus of the salient point under L shape master arm is centered by the rotating shaft of L shape master arm, with salient point to the distance of rotating shaft for radius, but the rising of bellows is vertical rising, at the uniform velocity move upward in process at salient point, the movement velocity of salient point on its arching trajectory reduces gradually, make its reaction speed slack-off, sensitivity step-down.
Utility model content
The technical problems to be solved in the utility model is: existingly at the uniform velocity to move upward in process at salient point to solve, the movement velocity of salient point on its arching trajectory reduces gradually, make its reaction speed slack-off, the problem of sensitivity step-down, the utility model provides a kind of sensitive-type compression-type temperature controller, by bellows end face is arranged to inclined plane, salient point is at the uniform velocity moved upward in process, the movement velocity of salient point on its arching trajectory is relatively at the uniform velocity, thus improve the reaction speed of thermostat, add its sensitivity.
The utility model solves the technical scheme that its technical problem adopts: a kind of sensitive-type compression-type temperature controller, comprise shell, cover plate, camshaft, cam bit, Clip Reed, L shape master arm, extension spring, adjustment plate, push rod, touch spring, spring leaf, pin C, pin L, moving contact and fixed contact, also comprise bellows, described L shape master arm bottom is provided with a salient point, described salient point contacts with bellows and connects, and the end face that described bellows contacts with salient point is an inclined plane.
Particularly, the angle of described inclined plane and horizontal plane is α, described α=10-15 °.
As preferably, described α=10 °.
The beneficial effects of the utility model are: a kind of sensitive-type compression-type temperature controller that the utility model provides, by bellows end face is arranged to inclined plane, salient point is at the uniform velocity moved upward in process, the movement velocity of salient point on its arching trajectory is relatively at the uniform velocity, thus improve the reaction speed of thermostat, add its sensitivity, when the angle of inclined plane and horizontal plane is 10 °, its sensitivity is best.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of a kind of sensitive-type compression-type temperature controller of the present utility model;

Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1 and Figure 2, a kind of sensitive-type compression-type temperature controller, comprise shell 1, cover plate 2, camshaft 3, cam bit 4, Clip Reed 5, L shape master arm 6, extension spring 7, adjustment plate 8, push rod 9, touch spring 10, spring leaf 11, pin C12, pin L13, moving contact 14 and fixed contact 15, also comprise bellows 16, L shape master arm 6 bottom is provided with a salient point 17, salient point 17 contacts with bellows 16 and connects, the end face that bellows (16) contacts with salient point 17 is an inclined plane 18, and inclined plane 18 is 10 ° with the angle of horizontal plane 19.
Its principle is: at the uniform velocity moving upward in process at salient point 17, the movement velocity of salient point 17 on its arching trajectory reduces gradually, compensate the slack-off speed of movement velocity on arching trajectory by arranging inclined plane 18, thus its reaction speed is increased, sensitivity uprises.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to right.
