Abstract
The utility model discloses a fuzzy controlled direct cooling refrigerator, which is characterized in that a display operating plate is arranged on the front surface of the refrigerator, and a signal line penetrates through a rotating shaft of a refrigerator door and is led to a master controller on the back of a refrigerator body; the utility model is also characterized in that a liquid crystal display is adopted, and the setting of the function is completed by different magnitudes of voltage. In the fuzzy controlled direct cooling refrigerator provided by the utility model, the display operating plate is arranged on the front surface of the refrigerator door, the display of the state of the utility model is definite, and setting of the function is simple and convenient.
Description
The utility model relates to direct cooling refrigerator, a kind of fuzzy control direct cooling refrigerator of more specifically saying so.
Direct cooling refrigerator of the prior art, because of its contour structures and controller circuit structure are limit, on state shows, generally all can only be by on the frame of casing top, charactron being set or luminous tube is finished, demonstration information is very limited; In function control, no matter be to adopt the steam pressure temperature controller, still adopt electronic temperature controller, all have control function singleness, unhandy defective jointly.Above-mentioned state shows and the function control mode can not satisfy especially the employing fuzzy control technology intellectuality refrigerator.
At present, also do not have the display operation plate is arranged on fuzzy control direct cooling refrigerator on the door of refrigerator.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part, provide a kind of state show clear and definite, feature operation is convenient, the display operation plate is arranged on fuzzy control direct cooling refrigerator on the door of refrigerator.
The purpose of this utility model is achieved through the following technical solutions:
The utility model comprises chamber door, casing, door pivot and the fuzzy controller that is made of display operation plate and main controller.
Of the present utility model being characterised in that:
(1), described display operation plate is arranged on the face of chamber door, the holding wire that is connected between display operation plate and the main controller is drawn from the display operation plate, passes door pivot to the main controller that is positioned at the casing rear portion.
(2), described display operation plate adopts LCDs, at LCDs and main control chip IC

The utility model is compared prior art and is had following advantage:
1, the utility model ingenious, reasonably utilized the door pivot of refrigerator, make display screen be arranged on the door of refrigerator, its state shows clear wash rice, eye-catching.
2, the utility model changes charactron or luminous tube is a LCDs, shows that information content improves greatly, show state is intuitive, clear.
3, the utility model function setting is to finish with different partial pressure value.Because this particular structure is provided with, and can make the holding wire of main controller reduce to minimum, is 7.Therefore, the function setting key can be arranged on the chamber door as the display operation plate together with display screen, whereby, and handled easily greatly.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model circuit theory diagrams.
By the following examples, in conjunction with the accompanying drawings, the utility model is further described.
Embodiment:
Referring to Fig. 1, main controller 3 is positioned at casing 2 rear portions, and display operation plate 4 is arranged in chamber door 1 face, and the holding wire 5 that comes from display operation plate 4 passes door pivot 6 to main controller 3, so lead-in wire is arranged under the prerequisite that guarantees the casing heat-insulating property, does not influence the overall structure of casing.
