Abstract
A constant-temperature reset-type pressure-type temperature controller possessing balance adjustment is disclosed. A gantry-type balance plate is arranged between a tail part of a horizontal section of a bearing plate and a lower hook portion of a balance tension spring. A central section of any side door post of the balance plate is extended inwardly so as to form a cantilever which is bent and deformed under stress. A top of a tail end of the cantilever is provided with an upward spur which is located on a vertical center axis 00' of the balance plate. Tappets of two sides of the door post are arranged in locating slots of two sides of a main body. The tail part of the horizontal section of the bearing plate is inserted into the balance plate and a lower part is contacted with the spur. The spur is located in the middle of two crosspoints of the tail part of the horizontal section of the bearing plate and vertical center axis 00' when the temperature controller is in an ON state and an OFF state. The temperature controller can rapidly and reliably adjust a balance critical position of the balance plate of the each temperature controller into an optimum balance position so that a long-term constant-temperature reset function is realized and accuracy, stability and reliability of a motion temperature are greatly increased.
Description
Technical field
The utility model relates to the mechanical temperature controller technical field, particularly a kind of constant temperature reset pressure type temperature controller with balanced adjustment.
Background technology
Compression-type temperature controller is widely used in the refrigeration control of refrigerator etc., and the gradient of temperature by the induction box house makes its sensitive switch break-make, thus the start-stop of control refrigerant compressor and realize temperature control.Wherein constant temperature reset pressure type temperature controller has changeless switch connection (resetting) action (ON) temperature and the user can disconnect by the switch that knob adjustment cam axle is regulated action (OFF) temperature, is mainly used in the two-door derect refrigerated refrigerator of automatic defrosting.The Chinese patent communique disclose notification number be CN201698960U, name is called the technical scheme of " constant temperature reset type temperature controller ".This thermostat is made of main body 1, construction of switch 2.Shown in this patent application specification accompanying drawing 3 ~ 5, wherein main body 1 is made of shell 3 and inner bellows 5 thereof, L-type master arm 4, portable plate 7, adjustable plate 6, two extension springs and adjustment cam shaft assembly.Described L-type master arm 4 one sides contact with bellows 5 by tappet, and pass the opening 61 of adjustable plate 6, opposite side links to each other with extension spring 82, the switching system of push rod 9 one ends and construction of switch 2 inside links together, it is outside but need be in contact with one another the on-off of pull switch system that the other end passes a side of L-type master arm 4 or a side.Adjustable plate 6 fluted 62 is used for fixedly extension spring 81, and extension spring 81 1 ends link to each other with adjustable plate 6, and the other end links to each other with portable plate 7.When thermostat temperature-sensitive section temperature begins to reduce from high temperature, bellows 5 shrinks, and the L-type master arm 4 that contacts with bellows 5 produces to bottom offset, because L-type master arm 4 passes adjustable plate 6 inside, can drive simultaneously adjustable plate 6 and move downward, extension spring 81 is in tensioning state.The opposite side of L-type master arm 4 then moves upward and swings left, drives push rod 9 to left movement, so that the switch that is connected with push rod 9 disconnects, thermostat is in the off state.Otherwise, when thermostat temperature-sensitive section temperature raises, bellows 5 is upheld, one side of the L-type master arm 4 that contacts with bellows 5 produces to top offset, and adjustable plate 6 moves upward under the effect of L-type master arm 4, bounces back under the effect of extension spring 81, L-type master arm 4 opposite sides move down and swing to the right, drive connected push rod 9 counter motions, so that the switch closure that is connected with push rod 9, thermostat is in the ON state.As seen, 5 need of bellows overcome the pulling force of extension spring 82 during the ON state, and extension spring 82 other ends are fixed on the shell 3, so ON state temperature immobilizes; Bellows 5 shrinks the pulling force that also need overcome extension spring 81 during the OFF state, and the pulling force of extension spring 81 is adjustable by portable plate 7 and adjustment cam shaft assembly, so OFF state temperature can be conditioned.
From the course of action of the ON state of above-mentioned thermostat and off state again in conjunction with its accompanying drawing 3 ~ 5 as seen, the relative altitude between the upper plane of the bottom contact-making surface of the opening 61 of adjustable plate 6 and adjustable plate 6 both sides boss is extremely important.If this relative altitude is too high, adjustable plate 6 still contacts L-type master arm 4 one side afterbodys in the time of will causing the ON state, and ON state temperature also can be changed with the diverse location of adjustment cam axle, forfeiture constant temperature function; If this relative altitude is excessively low, the opening 61 bottom contact-making surfaces of adjustable plate 6 still can not touch L-type master arm 4 one side afterbodys in the time of will causing the OFF state, and OFF state temperature can not be conditioned.Best relative altitude should be that balance critical localisation (being that opening 61 bottom contact-making surfaces just contact with L-type master arm 4 and the plane just contacts above with the groove of shell 3 on the adjustable plate 6 both sides boss position) is adjusted in the ON state of L-type master arm one side afterbody and the centre position of OFF state.This process of adjusting to optimum height is called the balanced adjustment process.
In sum, there is following shortcoming in above-mentioned constant temperature reset pressure type temperature controller: because the size of above-mentioned construction of switch 2, the length of push rod 9, the position of salient point, 90 ° of bending errors of L-type master arm 4, the accumulation of adjustable plate 6 aperture position foozles etc., thereby there is larger high and low position difference L-type master arm 4 afterbody positions when the ON state of each thermostat and OFF state, because it lacks the balanced adjustment link, therefore adjustable plate 6 openings 61 positions of its batch production can not guarantee that the balance critical localisation of each thermostat is the optimum position, and it is too high or too low and can not realize its electric temperature regulator function the balance critical localisation in most cases can to occur.Realize the electric temperature regulator function even can work during the product export that has, if but the too close ON state position of balance critical localisation or OFF state position, thermostat is (10 years designed lives of thermostat in long-term the use, about 200000 times) because wearing and tearing, distortion, the displacement of part, small variation will cause thermostat to lose efficacy.
Summary of the invention
