Below with reference to the accompanying drawings refrigerator according to the embodiment of the present invention is described.
According to the refrigerator of the embodiment of the present invention, comprising: casing (not shown), door body (not shown), trigger switch 110 and controller 120.
Particularly, be limited with a room in casing, a room includes but not limited to: refrigerating chamber, refrigerating chamber and/or fresh-keeping chamber.Door body is arranged on casing for room between opening and closing.Trigger switch 110 is for switching refrigerator between normal mode of operation and rotational speed monitor pattern.
It should be noted that, rotational speed monitor pattern ordinary circumstance does not use, and just uses when generally user or tester, the performance to refrigerator is tested.Particularly, when user or tester need to test the power consumption of refrigerator, when needing monitoring compressor 140 real-time rotate speed, just can enable rotational speed monitor pattern, refrigerator enters compared to normal mode of operation after this pattern, and the operation of its refrigerator controls constant, just than the many detection of normal mode of operation and the rotating speed of the compressor 140 of display refrigerator, and the control mode of refrigerator in normal mode of operation is prior art, do not repeat herein.
In one embodiment of the invention, in order to prevent maloperation, trigger switch 110 is Macintosh.Such as, pin freezing temperature adjustment key simultaneously and refrigerate temperature adjustment key and enter rotational speed monitor pattern in more than 5 seconds.As shown in Figure 1, in this example, trigger switch 110 is integrated in display unit 10, and the display of display unit 10 can be liquid crystal display.Be understandable that, selecting rotational speed monitor pattern or normal mode to be not limited to the mode of combination button, can also be other implementations.
Controller 120 runs for controlling compressor 140, and when trigger switch 110 will be switched to rotational speed monitor pattern at refrigerator, obtain the rotating speed of compressor 140 according to the square-wave signal of controller 120 output, and sent to by the rotating speed of compressor 140 display unit 10 of refrigerator to show.Can calculate the rotating speed of compressor 140 according to the square-wave signal of controller 120 output, specifically, the frequency dependence of the square-wave signal 2 that compressor 140 rotating speed and controller 120 export joins.Such as: the frequency * N of the rotating speed=square-wave signal of compressor 140, wherein, N is positive integer.
Particularly, controller 120 export the frequency of square-wave signal 2 and the running speed of compressor 140 be all generally linear relationship.Common compressor operating rotating speed=controller exports the frequency * 30 of square-wave signal 2.Such as, the frequency of the square-wave signal 2 that controller 120 exports is 1K, then the speed of service of compressor 140 is 30K.And the corresponding relation of the square-wave signal 2 that compressor 140 running speed and controller 120 export is realized by frequency conversion plate 130 as described in Figure 1, namely frequency conversion plate 130 pairs of square-wave signals 2 carry out frequency conversion, meet above-mentioned corresponding relation with the square-wave signal 2 making compressor 140 running speed and controller 120 export.
The general principle that compressor 140 realizes different rotating speeds is specifically described below with reference to Fig. 1.
As shown in Figure 1, the general principle that compressor 140 realizes different rotating speeds is: controller 120 is communicated by communication bus 1 with display unit 10, the square-wave signal of the exportable different frequency of controller 120, after frequency conversion plate 130 is changed, send the three-phase ac signal 3 of different frequency to drive compressor 140, compressor 140 runs different rotating speeds according to this signal.Wherein, the communication mode of communication bus 1 can be UART asynchronous communication means or single line communication mode, thus provides multiple choices for communication between controller 120 and display unit 10, and UART asynchronous communication means or single line communication mode communication stability strong.Particularly, controller 120 export the frequency of square-wave signal 2 and the running speed of compressor 140 be all generally linear relationship.Common compressor 140 running speeds=controller 120 exports square-wave signal 2 frequency * 30.Therefore, only need to know that square-wave signal 2 frequency that controller 120 exports just can know the running speed of compressor 140.
It should be noted that, the communication information between controller 120 and display unit 10 has a lot, comprises the communication information under normal mode, i.e. the temperature information of each room of refrigerator.When refrigerator is in rotational speed monitor pattern, need the running speed of display compressor 140 in real time, in order to transmit the communication information better, in one embodiment of the present of invention, add a communication byte D, for transmitting the real-time rotate speed of compressor 140, to show in display unit 10 better.Wherein, the rotating speed of this byte representation is D, unit: 1000rpm.Display unit 10 just reads this communication byte D after entering rotational speed monitor pattern, and is shown by display unit 10.
Embodiments of the invention make refrigerator switch between normal mode of operation and rotational speed monitor pattern by trigger switch, and when rotational speed monitor pattern, the rotating speed of compressor real time execution is obtained according to the square-wave signal of controller output, achieve the monitoring of compressor real time execution rotating speed, the display unit being simultaneously sent to refrigerator shows, save the testing tool of compressor rotary speed, there is the high and convenient and time-saving advantage of accuracy of detection, carry out performance calibration tape to user or tester to refrigerator to facilitate, there is high applicability.
As shown in Figure 2, the refrigerator of one embodiment of the invention enter rotational speed monitor pattern and the process run in rotational speed monitor pattern as follows:
Step S201, judges whether to enter rotational speed monitor pattern.Particularly, judge whether to trigger trigger switch, if trigger trigger switch, then refrigerator enters another pattern from present mode, if enter rotational speed monitor pattern, then performs step S202, if judge not enter rotational speed monitor pattern, then perform step S203.
Step S202, the rotary speed data of Read Controller communication byte D.
Under rotational speed monitor pattern, communication byte D sends display unit 10 to by communication bus 1, and then reads the rotary speed information of communication byte D.
Step S203, normally shows.In the normal mode, the temperature information of the normal each warm area of display refrigerator of display unit 10.
Step S204, display compressor 140 operates rotating speed.After execution of step S202, be presented at the real-time motion rotating speed of compressor 140 under rotational speed monitor pattern by display unit 10.
The Systematical control under the rotational speed monitor pattern of the embodiment of the present invention is specifically described below with reference to Fig. 3.
As shown in Figure 3, the step run under rotational speed monitor pattern according to the refrigerator of the embodiment of the present invention comprises:
Step S301, trigger switch 110 enters or exits rotational speed monitor pattern.
By entering rotational speed monitor pattern by the trigger switch 110 in display unit 10.If when being in rotational speed monitor pattern, then exit rotational speed monitor pattern by trigger switch 110.In order to prevent maloperation, in a preferred embodiment of the invention, trigger switch 110 is Macintosh.In other words, by entering by Macintosh or exiting rotational speed monitor pattern.
Step S302, if rotational speed monitor pattern is by rotational speed monitor mode flags position 1, sets to 0 rotational speed monitor pattern during normal mode.
Particularly, in order to more easily distinguish normal mode and rotational speed monitor pattern, in the software of display unit 10, a rotational speed monitor mode flags is set.If be in rotational speed monitor pattern, this is masked as 1; During normal mode, this is masked as 0.
Step S303, display unit 10 display module judges, whether is in rotational speed monitor pattern.During rotational speed monitor pattern, display compressor 140 rotating speed; Under normal circumstances, normal temperature is shown.
Particularly, when judging in display unit 10 control software design whether user requires to be in rotational speed monitor pattern, if under rotational speed monitor pattern, the display module of display unit 10 is the rotary speed data D(unit that runs through the compressor 140 that asynchronous communication or single line communication send of Read Controller 120 then: 1000rpm), display unit 10 is again by rotating speed that display module display compressor 140 runs.If when being in non-rotational speed monitor pattern, then the display module of display unit 10 normally shows the temperature of each warm area.Wherein, in order to distinguish display under rotational speed monitor and normal display, preferably, doing one and simply distinguishing display, as by degree Celsius icon flickering display.
Thus, the present invention adds than control in the past the difficulty that scm software writes, thus not needing the actual speed recording compressor operating under detecting instrument, can bring convenience to performance test.
According to the refrigerator of the embodiment of the present invention, add communication byte D, rotational speed monitor pattern is entered by the trigger switch of Macintosh mode, and pass to display unit by UART asynchronous communication or single line communication, thus the real-time rotate speed of display compressor, bring conveniently to performance test, thus make user or tester can under not using the instrument situations such as oscillograph, the real time execution rotating speed of direct reading compressor, more humane.
