Abstract
The utility model relates to an ordinary pressure type temperature controller of which the on-off temperature differential can reach 10 DEG C to 25DEG. C. A balance mechanism is additionally arranged above a bearing plate arranged in a main body of the existing ordinary pressure type temperature controller. When the temperature of a temperature sensing part rises, and a switch approaches to the on-state time, the balance mechanism is connected with the bearing plate so as to have effect. When the temperature of the temperature sensing part drops, and a switch approaches to the off-state time, the balance mechanism disengages from the bearing plate so as to have no effect. Thereby, the stress state of a control mechanism is effectively changed, and the on-off temperature differential range is enlarged. The utility model has the advantages of compact structure, no change on the exterior sizes and electric performance of the original temperature controller, convenient operation, and favorable safety performance.
Description
The utility model relates to temperature automatic control technology field, particularly a kind of large on-off temperature difference plain edition compression-type temperature controller.
Existing a kind of refrigerator, refrigerator are controlled usefulness as temperature plain edition compression-type temperature controller that is used for, by switch enclosure, corrugated tube, temperature-sensitive portion and control gear is formed, control gear is made up of main body and the bearing plate, adjustable plate, extension spring, the set screw that are contained in the main body, bearing plate drives push rod and makes switch motion.The start-stop temperature difference of the plain edition compression-type temperature controller of this kind structure realizes by adjusting the switch contact gap.Because the restriction of structure, there is certain limit in the switch contact gap, thereby in general its start-stop temperature difference is no more than 10 ℃.When the required start-stop temperature difference during greater than 10 ℃, the compression-type temperature controller of this kind structure just can not satisfy the demands.
The purpose of this utility model is to provide a kind of large on-off temperature difference plain edition compression-type temperature controller, and it can obtain the start-stop temperature difference of 10 ℃ of-25 ℃ of scopes.
The purpose of this utility model is achieved in that a kind of large on-off temperature difference plain edition compression-type temperature controller, comprise control gear, switch enclosure, corrugated tube, temperature-sensitive portion, control gear is by main body and be loaded on bearing plate and extension spring thereof in the main body, set screw, adjustable plate is formed, bearing plate drives push rod and makes switch motion, it is characterized in that: above bearing plate, be provided with balance plate, this balance plate one end is fixed on the main body with pivot pin, in riser upper end, balance plate middle part extension spring is housed, be connected to expansion screw between the extension spring other end and the main body, with the corresponding bearing plate of the balance plate other end on the adjustment screw is housed.
The member that reflects above-mentioned distinguishing characteristics technology all is contained in the main body of original plain edition compression-type temperature controller, and compression-type temperature controller physical dimension of the present utility model and installation dimension are identical with the plain edition compression-type temperature controller of original same model specification.
The course of work of the present utility model is such: when constantly being raise by controlling temperature, bellows expansion, produce one and go up thrust, the bearing plate fulcrum is rotated counterclockwise, by push rod pull switch closure, when switch closes on connection, adjusting the screw upper end contacts with balance plate, at this moment, by the controlling temperature bigger numerical that need continue to heat up, promptly produce a bigger last thrust, just can overcome the pulling force of balance plate and extension spring thereof, make bearing plate continue to rotate counterclockwise, switch closure, thereby the effect of the acquisition large on-off temperature difference around fulcrum.Behind the switch closure, the compressor starts refrigeration is constantly descended by controlling temperature, bellows contract, and last thrust constantly reduces, and when switch closed on off-state, balance plate separated with adjustment screw upper end.Thereby, by adjusting the pulling force of extension spring on the balance plate, just can correspondingly obtain the different large on-off temperature difference.
Advantage of the present utility model is:
(1) can obtain the large on-off temperature difference of 10 ℃ of-25 ℃ of scopes.
(2) member that is increased is installed in the plain edition compression-type temperature controller main body of original same model same specification, need not change the overall dimensions and the installation dimension of former temperature controller, thereby, compact conformation, easy to use.
(3) need not change the switch enclosure part of former plain edition compression-type temperature controller, thereby security performance is good.
Fig. 1 is the utility model structural representation.
Fig. 2 is original plain edition compression-type temperature controller principle of work synoptic diagram.
Fig. 3 is the utility model principle of work synoptic diagram.
By following embodiment the utility model is further elaborated.
Referring to Fig. 1, Fig. 2, shown in Figure 3, the present embodiment product is a WP series large on-off temperature difference plain edition compression-type temperature controller, and it is to improve to form on the basis of existing WP series plain edition compression-type temperature controller.Existing plain edition compression-type temperature controller is made up of control gear, switch enclosure 1, corrugated tube 13, temperature-sensitive portion 14, and control gear is by main body 12 and be loaded on the interior bearing plate 7 of main body 12 and extension spring 6, set screw 9, adjustable plate 8 are formed.Improvement part is: balance plate 4 is housed above bearing plate 7, these balance plate 4 one ends are fixed on the main body 12 with pivot pin 2, balance plate 4 medium positions are provided with a riser, extension spring 5 one ends are contained in its upper end, between extension spring 5 other ends and the main body 12 expansion screw 10 is housed, with the corresponding bearing plate 7 of balance plate 4 other ends on be equipped with and adjust screw 11, by adjusting screw 11 screw 11 is contacted with balance plate 4.Bearing plate 7 drives push rod 3 and makes switch motion.
