The utility model relates to mechanical type temperature control technology field, particularly a kind of manual subzero temperature compression-type temperature controller that automatically resets.
At present, be used as the compression-type temperature controller of temperature control in refrigerator, the refrigerator, when the strong cooling rate of needs is frozen, by what manually realize.This is because the interior nothing of temperature controller is set up automatic reset mechanism and can not be automatically reset.When needs reset, also need by manually hand-reset once more, it is very inconvenient therefore to use.
The purpose of this utility model is to provide a kind of manual subzero temperature compression-type temperature controller that automatically resets, and it can realize manual quick-frozen to set point of temperature, need not manually just can automatically reset once more.
Another purpose of the present utility model is that also being provided with a manual parallel-moving type for the ease of refrigerator, refrigerator production testing and daily use maintenance forces shut-down mechanism.
The purpose of this utility model is achieved in that a kind of manual subzero temperature compression-type temperature controller that automatically resets, it comprises: sensor, constitute by interior corrugated tube 12, kapillary bulb 13 of filling temperature-sensitive working medium, be used for transferring controlled temperature variation around the bulb to the corrugated tube displacement; Topworks is made up of push rod 14, microswitch K, is used to control compressor M work; The first lever balance mechanism between push rod 14 and corrugated tube 12, is made of bearing plate 11, extension spring 9, set screw 8, fulcrum 0, housing 7, is used for changing the corrugated tube displacement into the push rod displacement; The second lever balance mechanism between push rod 14 and bearing plate 11, is made of flat transverse slat 10, extension spring 5, adjustable plate 3, regulating wheel 2, set screw 6, fulcrum 01; Between balance plate 10 and adjustable plate 3, be provided with quick-frozen---resetting-mechanism, form by switch shaft 1, connecting rod 17, bent axle 4, pivot pin 15, small extension spring 16, spacing point 19, housing 7, it has constituted two revolute pairs and a moving sets, is used to control contacting and released state of balance plate 10 and bearing plate 11; Also be provided with parallel-moving type simultaneously and force shut-down mechanism, form, be used for forcing to turn-off microswitch K by banking stop 18, regulating wheel 2, adjustable plate 3, housing 7.
The principle of the present utility model and the course of work are such: a confined space that constitutes by corrugated tube 12, kapillary bulb 13, in fill temperature-sensitive working medium, form saturated vapour.The vapor pressure size is with proportional by controlling temperature around the bulb, controlled variation of temperature is changed into pressure change, cause the variation of corrugated tube displacement, its variation acts on the push rod 14 by two cover lever balance mechanisms, promote microswitch K, realize temperature control.Bulb is placed controlled temperature field, and when bulb temperature ratio was high by controlling temperature, saturated vapour pressure was big, the corrugated tube displacement increases, and makes push rod 14 forward by lever balance mechanism, and microswitch K contact is connected, the compressor M refrigeration of working descends the controlled device temperature.Thereupon, saturated vapour pressure descends, and corrugated tube 12 displacements reduce, and by lever balance mechanism, push rod 14 are retreated, and microswitch K contact disconnects, and compressor M quits work, and finishes temperature control just often, shown in following accompanying drawing 1.
When the manual depression quick-frozen---during switch shaft 1 in the resetting-mechanism, two revolute pairs and a moving sets motion that connecting rod 17, bent axle 4, pivot pin 15 and housing 7 constitute are stretched, and limited site 19 is spacing locked, promotes balance plate 10 around fulcrum 0
1Rotation makes balance plate 10 separate with bearing plate 11.Only be subjected to controlling the pulling force of spring 9 on the bearing plate 11, referring to shown in Figure 2.At this moment, because the bulb environment temperature is than by the controlling temperature height, line line pipe 12 displacements increase, and make push rod 14 forward by bearing plate 11, promote microswitch K contact and connect, compressor M work refrigeration quick-frozen.Along with the controlled device temperature descends, saturated vapour pressure descends, and corrugated tube 12 shrinks, and displacement reduces, and bearing plate 11 also rotates around fulcrum 0 thereupon.When quick-frozen during to the negative temperature of regulation, bearing plate 11 touches the G point of connecting rods 17, and locked connecting rod 17, bent axle 4, pivot pin 15 are threaded off, and under the effect of small extension spring 16 power, returns to tortuous state, quick-frozen---and resetting-mechanism and leverage break away from fully.Temperature controller returns to foregoing normal temperature control state.When connecing down quick-frozen---behind the resetting-mechanism,, at this moment,, recover normal temperature control state as long as can stop quick-frozen with portable switch shaft 1 if do not think quick-frozen.This is the ultimate principle that realizes this temperature controller logic function.
It is manually microswitch to be forced to turn-off that parallel-moving type is forced the effect of shut-down mechanism, is convenient to refrigerator, refrigerator production testing and daily use maintenance.When needs were forced to turn-off, as long as regulating wheel 2 is screwed into the pressure cut-off point, banking stop 18 spurred bearing plate 11 by force push rod 14 is retreated because of being subjected to adjustable plate 3 tractives at this moment, and microswitch K forces to turn-off.At whole course of action is that 18 of banking stops are done translation motion, thereby the volume that takes up room is little.
Advantage of the present utility model is:
(1) adopt corrugated tube---pressure---displacement transducer of making temperature, displacement is big, good linearity, and assembly technology is easy, the yield rate height.
(2) compact overall structure, volume are little, use very convenient.
