Preferably, it also comprises general supply and controls contact, and described general supply controls contact and is connected with described temperature adjustment knob, and the disconnection of described general supply control contact is controlled by described temperature adjustment knob with being connected.
Preferably, the multiple gear of described temperature adjustment knob, when being transferred to lowest gear, described temperature adjustment knob controls contact by general supply described in the protruding jack-up of adjustment makes its two ends separately.
Preferably, the second end of described 3rd lever also connects one second adjustment screw by a spring, and described second adjustment screw is for adjustment temperature of starting shooting.
Preferably, freon is full of in described steam bellows.
The present invention has following beneficial effect:
The present invention can regulate the temperature in refrigerator, also can complete switch to whole refrigerator power supply by temperature adjustment knob, complete the major control to whole refrigerator by means of only a knob;
To temperature coarse adjustment simultaneously when the present invention adjusts screw for starting shooting by second, finely tune temperature when the first set screw is for shutting down, scope and the precision of adjustment are well ensured.
Certainly, implement arbitrary product of the present invention might not need to reach above-described all advantages simultaneously.
Accompanying drawing explanation
The refrigerator thermostat principle schematic that Fig. 1 provides for the embodiment of the present invention.
Embodiment
Embodiment
As shown in Figure 1, a kind of refrigerator thermostat, it comprises temperature adjustment knob 1, first lever 10, second lever 9, the 3rd lever 8 and compressor control contact 3, steam bellows 7, first lever 10 is connected with the second lever 9 by a spring, second lever 9 is connected with the 3rd lever 8 by the first set screw 4, regulates temperature when the first set screw 4 is for shutting down; In the present embodiment, the first set screw 4 is for fine setting.
3rd lever 8 is L-type, and comprise first end and the second end, its first end is connected with steam bellows 7, and its second end is connected with compressor control contact 3;
One end of kapillary temperature-sensitive head 6 is connected with steam bellows 7, and the other end of kapillary temperature-sensitive head 6 is connected with refrigerator inwall, gassy in steam bellows 7.Freon is full of in the steam bellows that the present embodiment provides.Certain the present invention also can adopt other gases to replace freon, and the present embodiment is only described for freon.
The refrigerator thermostat that the present embodiment provides also comprises general supply and controls contact 2, and general supply controls contact 2 and is connected with temperature adjustment knob 1, and the disconnection of general supply control contact 2 is controlled by temperature adjustment knob 1 with being connected.
The multiple gear of temperature adjustment knob, when being transferred to lowest gear, described temperature adjustment knob controls contact by general supply described in the protruding jack-up of adjustment makes its two ends separately.Be divided into 0 to 5 grades for the temperature adjustment knob of the present embodiment, when temperature adjustment knob selects 0 grade, general supply controls two ends, contact and disconnects, and the power supply of refrigerator is cut off; 1-5 shelves are selected to represent different Temperature numerical respectively.
