Described Based Intelligent Control plate also includes standby port.
The utility model with respect to the beneficial effect of prior art is:
(1) the utility model can guarantee to improve to greatest extent refrigerator refrigerating efficiency, energy saving;
(2) the utility model can be avoided frequency-changeable compressor to start shooting continually and shut down the service life of prolongation frequency-changeable compressor;
(3) the utility model makes refrigerator refrigeration system running time still less, reaches quiet effect.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the schematic diagram of the utility model control device structure;
Fig. 2 is the composition block diagram of the utility model control device;
The specific embodiment
See figures.1.and.2, the control device of a kind of frequency conversion refrigerator of the utility model, comprise VFC plate 3 and the Based Intelligent Control plate 2 that is connected with VFC plate 3, the input of described Based Intelligent Control plate 2 is connected with temperature sensor 1, and the output of Based Intelligent Control plate 2 is connected with the input of VFC plate 3.

When using the utility model control device, the refrigerator energising begins refrigeration, control device is according to the unlatching of the temperature control frequency-changeable compressor of the temperature of refrigerating chamber and refrigerating chamber and setting respectively, system is after operation a period of time, according to the rate temperature change and the environment temperature of refrigerating chamber, refrigerating chamber, regulate the operating frequency of frequency-changeable compressor automatically, repeat this process at set intervals, make refrigerating chamber, refrigerating chamber keep the temperature of setting, can keep refrigerating efficiency the highest like this; Specifically comprise the steps:
(1) control program with refrigerator frequency-changeable compressor 4 deposits in the program storage master chip of VFC plate 3;
(2) refrigerator energising starts refrigerator, frequency-changeable compressor 4 runnings, this moment VFC plate 3 and also POST of Based Intelligent Control plate 2;
(3) Based Intelligent Control plate 2 by the program setting of VFC plate 3, need to determine rotating speed by temperature sensor 1 perception ambient temperature, drives frequency-changeable compressor 4 runnings;
(4) VFC plate 3 by program setting, is adjusted the rotating speed of frequency-changeable compressor 4 according to the running cumulative time of the temperature information and the frequency-changeable compressor 4 of Based Intelligent Control plate 2 automatically.
Described Based Intelligent Control plate 2 passes through temperature sensor 1 sense ambient temperature, and by VFC plate port 23 temperature information is sent to VFC plate 3, drives frequency-changeable compressor 4 and rotates; By rotary speed instruction port 24 rotary speed parameter of frequency-changeable compressor 4 is imported intelligent control chip 21 simultaneously.
Described intelligent control chip 21 is according to the control program of inner setting, according to the environment temperature of input and the accumulated running time of frequency-changeable compressor 4, be sent to VFC plate 3 by VFC plate port 23, adjust the operating frequency and the rotating speed of frequency-changeable compressor 4 automatically.
, by program debugging port 25 write-in programs the control program of intelligent control chip 21 inner settings is adjusted according to the model of refrigerator and function.
Adopt the refrigerator of the utility model control device, on the basis of original VFC plate 3, increase Based Intelligent Control plate 2, environment temperature and frequency-changeable compressor accumulated running time are increased in the control of refrigerator operation, by the control device of refrigerator according to the temperature of refrigerating chamber, refrigerating chamber, cooling rate, environment temperature and compressor accumulated running time, control the operating frequency of frequency-changeable compressor 4 in real time, avoid high frequent start and shutdown, guarantee accurately control compressor rotary speed, prolong the service life of compressor; The utility model can improve the refrigerating efficiency of refrigerator to greatest extent, and cooling is fast, and energy consumption is little, is easy to energy-conservation; The utility model makes refrigerator refrigeration system running time still less, reaches quiet effect; Use refrigerator food cold storing and fresh-keeping of the present utility model effective.
