Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the temperature controller that the specific embodiment of the invention provides.
A kind of temperature controller with temperature-compensating, comprise shell 1, heating compensation assembly, be located at described shell 1 inside mechanical component 2, be located at warming assembly 3 bottom described shell 1, the capillary 4 that described warming assembly 3 comprises bellows and is connected with described bellows.Wherein, described heating compensation assembly effectively can enhance the low temperature tolerant ability of temperature controller, solves the defect that cannot normally start in existing temperature controller low temperature environment simultaneously.
Described heating compensation assembly comprises temperature sense switch 61 and heater 62, and described enclosure is located at by described heater 62, and is connected 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 detects temperature controller the need of temperature-compensating, if desired temperature-compensating, then temperature sense switch 61 is connected; Otherwise then temperature sense switch 61 disconnects.Described temperature sense switch 61 can be located at the outer surface of described shell, also can be located at the responsive to temperature district outside described temperature controller, and its position of installing accurately can detect the variations in temperature of temperature controller.
Described heater 62 is resistance wire or resistance electrothermal sheet, and for heating temperature control device, the inside of described shell 1 is located at by described heater 62.
Fig. 2 and 3 is the structural representation of the electric interfaces assembly of the temperature controller that the specific embodiment of the invention provides and the circuit diagram of heating compensation assembly respectively.
Described electric interfaces component internal is provided with the L terminals be connected with Compressor Group 6, the C terminals be connected with power supply and common port H terminals.The on-off switch 55 being provided with the normally closed switch 54 for manually disconnecting between described L terminals 52 with described C terminals 53 and being connected in series with described normally closed switch 54.The two ends of described heater 62 are connected with H terminals 51 and C terminals 53 respectively, and described heater 62 is in parallel with the concatermer that normally closed switch 54 and on-off switch 55 form, namely in parallel with temperature controller.The two ends of described temperature sense switch 61 go between with the H terminals 51 of described housing exterior respectively and L terminals 52 go between is connected.
As shown in Figure 3, on-off switch 55 is connected, and when namely described L terminals 52 are with 53 conducting of described C terminals, Compressor Group 6 works, and heater 62 is shorted, and does not work.On-off switch 55 disconnects, namely when described L terminals 52 disconnect with described C terminals 53, if described temperature sense switch 61 is connected, the described H terminals 51 being namely positioned at described temperature controller outside go between the conducting that to go between with described L terminals 52, and heater 62 is connected and implemented heating compensation to temperature controller; If described temperature sense switch 61 disconnects, described H terminals 51 lead-in wire being namely positioned at described temperature controller outside goes between with described L terminals 52 and disconnects, and described heater 62 is disconnected, and does not work.
Fig. 4 is the method flow diagram of the temperature-compensating of temperature controller.
A method for temperature controller temperature-compensating, implement as follows:
S00: preset starting point temperature value, i.e. the starting point temperature value at temperature-sensitive position.
S10: if during the starting point temperature value of the temperature of temperature controller body lower than temperature-sensitive position, temperature sense switch 61 closes, and heater 62 is worked, carries out temperature-compensating to described temperature controller body.
S20: if during the starting point temperature value of the temperature of temperature controller body higher than temperature-sensitive position, temperature sense switch 61 disconnects, and described heater 62 does not work.
During concrete use, when environment temperature is higher, such as: spring, summer, autumn, temperature sense switch 61 can not be connected, and no matter whether described L terminals 52 disconnect with described C terminals 53, and heater 62 all can not work, now, the temperature of temperature controller is not less than the starting point at temperature-sensitive position.
When environment temperature is lower, such as: the eastern season that temperature is lower, the temperature of temperature controller is lower than the starting point at temperature-sensitive position, temperature controller cannot start, and when namely refrigerator cannot start, described L terminals 52 disconnect with described C terminals 53, namely on-off switch 55 disconnects, temperature sense switch 61 is connected, and heater 62 is started working, and starts heating to temperature controller.After heating, the temperature that temperature controller temperature is progressively increased to temperature controller is equal to or higher than the starting point at temperature-sensitive position, now, if refrigerator needs to start, on-off switch 55 is connected, and namely described L terminals 52 are connected with described C terminals 53, Compressor Group 6 starts, refrigerator normally works, and heater 62 two ends are shorted simultaneously, quit work.Therefore, because heater 62 exists, when ensure that refrigerator needs to start, the temperature of temperature controller is not less than the starting point at temperature-sensitive position, and refrigerator can normally start.
The present invention is described by preferred embodiment, and those skilled in the art know, without departing from the spirit and scope of the present invention, can carry out various change or equivalence replacement to these characteristic sum embodiments.The present invention is not by the restriction of specific embodiment disclosed herein, and other embodiments fallen in the claim of the application all belong to the scope of protection of the invention.
