Embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment.
Fig. 1 is the structural representation of the temperature controller that provides of the utility model embodiment.
A kind of temperature controller that is applicable to low temperature environment, comprise shell 1, heat compensation assembly, be located at described shell 1 inside mechanical component 2, be located at the temperature sense assembly 3 of described shell 1 bottom, described temperature sense assembly 3 comprises corrugated tube and the kapillary 4 that is connected with described corrugated tube.Wherein, described heating compensation assembly can effectively strengthen the low temperature tolerance of temperature controller, has solved the defective that can't normally start in the existing temperature controller low temperature environment simultaneously.
Described heating compensation assembly comprises temperature sense switch 61 and well heater 62, and described well heater 62 is located at described enclosure, and links to each other with the terminals of electric interfaces assembly 5 inside, and described electric interfaces assembly 5 is positioned on the sidewall of described shell 1.
Described temperature sense switch 61 can be magnetic switch, also can be temperature switch, and its effect is to detect temperature controller whether to need temperature compensation, if need temperature compensation, then temperature sense switch 61 is connected; Otherwise then temperature sense switch 61 disconnects.Described temperature sense switch 61 can be located at the outside surface of described shell, also can be located at the responsive to temperature district outside the described temperature controller, and the temperature variation that the position of its installation can accurately detect temperature controller gets final product.
Described well heater 62 is resistance wire or resistance electric heating piece, is used for the heating temperature control device, and described well heater 62 is located at the inside of described shell 1.
Fig. 2 and 3 is respectively the structural representation of electric interfaces assembly of the temperature controller that provides of the utility model embodiment and the circuit diagram of heating compensation assembly.
Described electric interfaces component internal is provided with the L terminals that link to each other with Compressor Group, the C terminals that link to each other with power supply, reaches common port H terminals.Be provided with between described L terminals 52 and the described C terminals 53 for the normally closed switch 54 that manually disconnects, and the on-off switch 55 that is connected in series with described normally closed switch 54.The two ends of described well heater 62 link to each other with H terminals 51 and C terminals 53 respectively, and described well heater 62 is in parallel, namely in parallel with temperature controller with the concatermer that normally closed switch 54 and on-off switch 55 are formed.The two ends of described temperature sense switch 61 link to each other with H terminals 51 lead-in wires and L terminals 53 lead-in wires of described housing exterior respectively.
As shown in Figure 3, on-off switch 55 is connected, i.e. during described L terminals 52 and described C terminals 53 conductings, and Compressor Group 6 work, well heater 62 is not worked by short circuit.On-off switch 55 disconnects, when being described L terminals 52 and 53 disconnections of described C terminals, if described temperature sense switch 61 is connected, namely be positioned at described H terminals 51 lead-in wires and described L terminals 53 lead-in wire conductings of described temperature controller outside, well heater 62 is connected temperature controller is implemented to add thermal compensation; If described temperature sense switch 61 disconnects, described H terminals 51 lead-in wires that namely are positioned at described temperature controller outside disconnect with described L terminals 53 lead-in wires, and described well heater 62 is disconnected, and does not work.
