Description
The utility model relates to a kind of refrigerator attemperator, particularly a kind of refrigerator auto thermal compensation device.The technique for temperature compensation field that belongs to refrigerator.
Technique for temperature compensation is mainly used in the single control of two temperature refrigerators, and (the single control of so-called two temperature refrigerators are meant: refrigerator is provided with freezing and two or more humidity provinces such as refrigeration, and only with the work of temperature controller control compressor), in the single control of two temperature refrigerator, the unlatching of control of the temperature of refrigerator and compressor or out of service be to finish by the temperature controller in the refrigerating chamber, when the temperature in the refrigerating chamber reaches the setting controlling value of temperature controller, temperature controller is just cut off the electricity supply, compressor is quit work, and this moment, refrigerating chamber and refrigerating chamber all stopped refrigeration.In winter; because environment temperature is lower; temperature and environment temperature in the refrigerating chamber are more approaching; always refrigerate indoor temperature prior to reaching setting value in the refrigerating chamber, and after placing the detected temperature of temperature-sensitive head of refrigerating chamber to reach setting value, temperature controller moves immediately; cut off the electricity supply; compressor shutdown, refrigeration system stop refrigeration, cause the temperature of refrigerating chamber can not reach setting value.Given this; in order to make the temperature of freezer compartment of refrigerator reach setting value in winter; a kind of effective way is to take technique for temperature compensation; one compensation thermal source promptly is set on the next door of temperature controller; the temperature-sensitive head of temperature controller is unlikely detects desired temperature too early, thereby avoid that compressor is shut down too early, freezer temperature can not reach setting value.
What use in refrigerator at present is manual technique for temperature compensation, the principle of this manual technique for temperature compensation: set up a temperature-compensating thermal source (resistive heater or bulb etc.) at refrigerating chamber, this thermal source is by a manual switch control, in winter, hand switch closes, the thermal source heating, the temperature of compensation refrigerating chamber, make the unlikely design temperature that reaches too early of temperature controller, prolong the available machine time of compressor, refrigerating chamber can reach design temperature; In summer, hand switch disconnects, and thermal source does not generate heat, and temperature controller is pressed design temperature and detected, the compressor operate as normal.Also there is following shortcoming in this manual technique for temperature compensation: many users fail to read over the refrigerator operation instructions, do not know the effect of temperature-compensating switch, do not carry out the switching conversion of switch when being everlasting seasonal variations, causing the winter refrigerating chamber can not reach design temperature, food rots; Summer refrigerating chamber cold excessively, the waste electric energy.
The purpose of this utility model is to need the shortcoming of artificial change-over switch state in order to overcome prior art, and a kind of refrigerator auto thermal compensation device is provided.
The purpose of this utility model can reach by taking following measure: refrigerator auto thermal compensation device, comprise the temperature controller of forming by temperature-sensitive head and temperature adjustment knob, its design feature is: also comprise with temperature sensitive automatic switch and be positioned at the temperature-compensating thermal source on temperature controller next door, the temperature-compensating thermal source, temperature-sensitive head and temperature adjustment knob are fixedly set in the inner chamber of cold compartment of refrigerator, temperature sensitive automatic switch is series at the electric power loop of temperature-compensating thermal source, the power supply of control temperature-compensating thermal source, temperature sensitive automatic switch is arranged at outside the refrigeratory body or the inboard of refrigerator outer wall, the automatic testing environment temperature of temperature sensitive automatic switch, and according to the on-off of the power circuit of environment temperature control temperature-compensating thermal source.
The purpose of this utility model also can reach by taking following measure:
The temperature-compensating thermal source is resistive heater, bulb or fluorescent tube.
Compared with prior art, the utlity model has following outstanding advantage:
1. in winter, environment temperature is lower, temperature sensitive automatic switch auto-closing, and temperature-compensating thermal source heating power, the refrigerator temperature compensator enters the temperature-compensating state automatically; Summer, environment temperature is higher, temperature sensitive automatic switch automatic disconnection, the outage of temperature-compensating thermal source is not generated heat, and the refrigerator temperature controller enters not temperature compensated state automatically, thereby the compressor that guarantees refrigerator is all to move time enough in summer or winter, promptly winter freezing indoor temperature can reach design temperature, prevent that food from rotting, summer refrigerating chamber only cold, saves energy.
2. simple in structure, with low cost, function admirable, easy to use.
Below in conjunction with accompanying drawing the utility model is described in detail:
Fig. 1 is the structural representation of the utility model embodiment 1.
As can be seen from Figure 1, present embodiment 1 comprises temperature sensitive automatic switch 1, temperature-compensating thermal source 2, temperature controller 3, temperature controller 3 is made up of temperature-sensitive head 4 and temperature adjustment knob 5, temperature-compensating thermal source 2, temperature-sensitive head 4 and temperature adjustment knob 5 are fixedly set in the inner chamber of cold compartment of refrigerator 6, it is external and connect with the power circuit of temperature-compensating thermal source 2 that temperature sensitive automatic switch 1 is positioned at refrigerating chamber 6, thereby the on-off of the power circuit of control temperature-compensating thermal source 2, temperature-compensating thermal source 2 adopts incandescent lamp bulb.
Other embodiment of the present utility model are: temperature-compensating thermal source 2 adopts resistive heater or fluorescent tube, and all the other are with embodiment 1.
As can be seen from Figure 1, because the effect of temperature-compensating thermal source 2, when its heating power, the temperature around the temperature-sensitive head 4 can corresponding rising, have only extraneous temperature around it is reduced, so temperature-sensitive head 4 to detect time of design temperature longer.Because temperature sensitive automatic switch 1 has the function of automatic testing environment temperature and automatic on-off, therefore, in winter, environment temperature is lower, temperature sensitive automatic switch 1 auto-closing, temperature-compensating thermal source 2 heating powers, the temperature compensator 3 of refrigerator enters the temperature-compensating state automatically, thereby guarantee that freezing indoor temperature can reach design temperature, prevent that effectively food from rotting; In summer, environment temperature is higher, temperature sensitive automatic switch 1 automatic disconnection, and 2 outages of temperature-compensating thermal source are not generated heat, and refrigerator temperature controller 3 enters not temperature compensated state automatically, thereby guarantees that refrigerating chamber is only cold, saves energy.
