Description
Technical field
The present invention relates to the mechanical temperature controller technical field, particularly a kind of compression-type temperature controller that is used for refrigerator control refrigerant compressor start and shutdown and other auxiliary circuit.
Background technology
Compression-type temperature controller is widely used in the control of refrigerator refrigeration, and existing a kind of compression-type temperature controller with auxiliary switch is made up of the bellows in the main body, bearing plate, temperature adjustment spring, regulating shaft assembly and switch enclosure assembly, referring to Fig. 1, shown in Figure 2.Wherein the switch enclosure assembly is made up of switch enclosure 1, C terminal 2, L terminal 3, H terminal 4, movable contact spring 5, auxiliary contact 6, bow spring 7, moving contact 8, H fixed contact 9, L fixed contact 10, auxiliary contact 11, auxiliary push-rod 12.C terminal 2, moving contact 8, movable contact spring 5, bow spring 7 have constituted the main switch that is subjected to temperature control and the kick action takes place with L terminal 3, L fixed contact 10, and auxiliary contact 6 is riveted on the L terminal 3, auxiliary contact 6 tool elasticity and predeformation is arranged, and by being riveted on auxiliary contact 11 on the auxiliary contact 6 contact formation with H fixed contact 9 closed circuit.When rotating regulating shaft to the forced shutdown position, the cam of regulating shaft assembly promotes auxiliary contact 6 actions by auxiliary push-rod 12, making auxiliary contact 6 is fulcrum flexural deformation with its riveting point on L terminal 3, make auxiliary contact 11 break away from H fixed contact 9, realize forced shutdown function the control main line.Because H terminal 4 is used to realize the forced shutdown function,, can only be confined to the form of single-pole single-throw(SPST so this three terminals switch enclosure can not be realized the function of single-pole double throw.This switch form can adopt " closed tripper " form, by adopt 2 cylindrical push rods and boss cooperate and " n " type explosion prevention function is realized in the junction of glue envelope switch enclosure, terminal, dividing plate.The patent No. be ZL02249191.0's " a kind of explosion-proof type compression-type temperature controller " with auxiliary switch disclose this technical scheme.
The electrical schematic diagram of the compression-type temperature controller of above-mentioned single-pole single-throw(SPST band auxiliary switch constitutes the main switch that is subjected to temperature control and the kick action takes place as shown in Figure 3 between C terminal 2 and the L terminal 3; And H terminal 4 is connected on the L terminal 3 by auxiliary contact 11 and auxiliary contact 6, constitutes auxiliary switch, can realize the forced shutdown function between L terminal 3 and the H terminal 4 when rotating regulating shaft to the forced shutdown position.Because H terminal 4 is used to auxiliary switch and realizes the forced shutdown function, so the structure that this three terminals switch enclosure is a kind of single-pole single-throw(SPST band auxiliary switch.A kind of application example of compression-type temperature controller in refrigerator of single-pole single-throw(SPST band auxiliary switch is referring to shown in Figure 4, refrigerator generally all is provided with and heats compensating resistance R winter now, be used to prevent that the winter environment temperature is low, the phenomenon that may cause refrigerator not started shooting takes place.The solution that adopts is a heating resistor R in parallel between C terminal 2 and L terminal 3, and add and change hand switch or automatic thermal sensitive K switch a summer in winter, when ambient temperature was higher, summer in winter, change over switch K disconnected, when ambient temperature was low, summer in winter, change over switch K connected.When summer in winter, change over switch K disconnected, the main switch that is connected between C terminal 2 and the L terminal 3 was normally controlled compressor D work.Change over switch K connects when summer in winter, when main switch is connected, summer in winter, change over switch K and heating resistor R were because of inoperative by short circuit, and compressor D starts refrigeration, when reaching the setting shutoff temperature, main switch disconnects, heating resistor R begins heating, because heating resistor R resistance is chosen very greatly, electric current is very little, by the undercurrent of compressor D, compressor D is just quit work.Heating resistor R heats to turn-on temperature, and then the main switch closure makes compressor D restart the start refrigeration.The weak point that this kind technical scheme exists is; because compressor alives for a long time, the one, compressor there is detrimental effect, the 2nd, the design that has the part compressor to adopt does not have Weak current to pass through when not allowing to shut down; otherwise just can not normally start start, cause and generally to promote the use of.
