Below with reference to the refrigerator of accompanying drawing description according to the embodiment of the invention.
Refrigerator according to the embodiment of the invention comprises: casing (not shown), door body (not shown), trigger switch 110 and controller 120.
Particularly, be limited with a chamber in the casing, a chamber includes but not limited to: refrigerating chamber, refrigerating chamber and/or fresh-keeping chamber.Chamber between the door body is installed in and is used on the casing opening and closing.Trigger switch 110 is used for refrigerator is switched between normal mode of operation and rotational speed monitor pattern.
Need to prove, rotational speed monitor pattern ordinary circumstance is not used, and generally just uses when user or tester test the performance of refrigerator.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 the rotational speed monitor pattern, refrigerator enters after this pattern than normal mode of operation, and the operation of its refrigerator control is constant, just manys the rotating speed of compressor 140 of detection and display refrigerator than normal mode of operation, and the control mode of refrigerator in normal mode of operation is prior art, do not do herein and gives unnecessary details.
In one embodiment of the invention, in order to prevent maloperation, trigger switch 110 is Macintosh.For example, pin simultaneously freezing temperature adjustment key and enter the rotational speed monitor pattern more than 5 seconds with refrigeration temperature adjustment key.As shown in Figure 1, in this example, trigger switch 110 is integrated in display unit 10, and the demonstration of display unit 10 can be liquid crystal display.Be understandable that, select rotational speed monitor pattern or normal mode to be not limited to the mode of combination button, can also be other implementations.
Controller 120 is used for 140 operations of control compressor, and will be when refrigerator switches to the rotational speed monitor pattern at trigger switch 110, obtain the rotating speed of compressor 140 according to the square-wave signal of controller 120 output, and the display unit 10 that the rotating speed of compressor 140 sends to refrigerator is shown.Can calculate the rotating speed of compressor 140 according to the square-wave signal of controller 120 outputs, particularly, the frequency dependence connection of the square-wave signal 2 of compressor 140 rotating speeds and controller 120 outputs.For example: the frequency * N of the rotating speed=square-wave signal of compressor 140, wherein, N is positive integer.
Particularly, the frequency of the square-wave signal 2 of controller 120 outputs and the running speed of compressor 140 generally all are linear relationships.The frequency * 30 of common compressor operating rotating speed=controller output square-wave signal 2.For example, the frequency of the square-wave signal 2 of controller 120 outputs is 1K, and then the speed of service of compressor 140 is 30K.And the corresponding relation of the square-wave signal 2 of compressor 140 running speeds and controller 120 outputs is realized by frequency conversion plate 130 as described in Figure 1, be that 130 pairs of square-wave signals of frequency conversion plate 2 carry out frequency conversion, so that the square-wave signal 2 of compressor 140 running speeds and controller 120 outputs satisfies above-mentioned corresponding relation.
Specifically describe the basic principle that compressor 140 is realized different rotating speeds below with reference to Fig. 1.
As shown in Figure 1, compressor 140 realizes that the basic principle of different rotating speeds is: controller 120 communicates by communication bus 1 with display unit 10, the square-wave signal of controller 120 exportable different frequencies, come drive compression machine 140 through the three-phase ac signal 3 that sends different frequency after 130 conversions of frequency conversion plate, compressor 140 is according to the different rotating speed of this signal operation.Wherein, the communication mode of communication bus 1 can be UART asynchronous communication means or single line communication mode, thereby for the communication between controller 120 and the display unit 10 provides multiple choices, and UART asynchronous communication means or single line communication mode communication stability are strong.Particularly, the frequency of the square-wave signal 2 of controller 120 outputs and the running speed of compressor 140 generally all are linear relationships.Common compressor 140 running speeds=controller 120 output square-wave signals 2 frequency * 30.Therefore, square-wave signal 2 frequencies that only need to know controller 120 outputs just can be known the running speed of compressor 140.
Need to prove, the communication information between controller 120 and the display unit 10 has a lot, comprises the communication information under the normal mode, i.e. the temperature information of each chamber of refrigerator.When refrigerator is in the rotational speed monitor pattern, need to show in real time the running speed of compressor 140, in order to transmit better the communication information, in one embodiment of the present of invention, increased a communication byte D, be used for the real-time rotate speed of transmission compressor 140, better shown in display unit 10.Wherein, the rotating speed of this byte representation is D, unit: 1000rpm.Display unit 10 just reads this communication byte D after entering the rotational speed monitor pattern, and shows by display unit 10.
Embodiments of the invention switch refrigerator by trigger switch between normal mode of operation and rotational speed monitor pattern, and when the rotational speed monitor pattern, obtain the rotating speed of compressor real time execution according to the square-wave signal of controller output, realized the monitoring of compressor real time execution rotating speed, the display unit that sends to simultaneously refrigerator shows, save the testing tool of compressor rotary speed, has the high and convenient and time-saving advantage of accuracy of detection, refrigerator is carried out performance test for user or tester and bring convenience, have high applicability.
As shown in Figure 2, the refrigerator of one embodiment of the invention enter the rotational speed monitor pattern and the process in the rotational speed monitor pattern, moved as follows:
Step S201 judges whether to have entered the rotational speed monitor pattern.Particularly, judge whether to have triggered trigger switch, if triggered trigger switch, then refrigerator enters another pattern from present mode, if entered the rotational speed monitor pattern, and execution in step S202 then, do not enter rotational speed monitor pattern, then execution in step S203 if judge.
Step S202, the rotary speed data of Read Controller communication byte D.
Under the 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, the normal demonstration.Under normal mode, the temperature information of display unit 10 normal each warm area of display refrigerator.
Step S204 shows compressor 140 running rotating speeds.After execution of step S202, be presented at the real-time motion rotating speed of rotational speed monitor pattern lower compression machine 140 by display unit 10.
Specifically describe the system's control under the rotational speed monitor pattern of the embodiment of the invention below with reference to Fig. 3.
As shown in Figure 3, the step of moving under the rotational speed monitor pattern according to the refrigerator of the embodiment of the invention comprises:
Step S301, trigger switch 110 enters or withdraws from the rotational speed monitor pattern.
By entering the rotational speed monitor pattern by the trigger switch 110 on the display unit 10.If when being in the rotational speed monitor pattern, then withdraw from the rotational speed monitor pattern by trigger switch 110.In order to prevent maloperation, in a preferred embodiment of the present invention, trigger switch 110 is Macintosh.In other words, by enter or withdraw from the rotational speed monitor pattern by Macintosh.
Step S302 is if the rotational speed monitor pattern during normal mode sets to 0 rotational speed monitor mode flags position 1 with the rotational speed monitor pattern.
Particularly, in order more easily to distinguish normal mode and rotational speed monitor pattern, in the software of display unit 10, set a rotational speed monitor mode flags.If be in the rotational speed monitor pattern, this is masked as 1; During normal mode, this is masked as 0.
Step S303, display unit 10 display modules are judged, whether are in the rotational speed monitor pattern.During the rotational speed monitor pattern, show compressor 140 rotating speeds; Under normal circumstances, show normal temperature.
Particularly, judge when whether the user requires to be in the rotational speed monitor pattern in the display unit 10 control softwares, if under the rotational speed monitor pattern, the display module of display unit 10 is the rotary speed data D(unit of compressor 140 operations that send through asynchronous communication or single line communication of Read Controller 120 then: 1000rpm), display unit 10 shows the rotating speed of compressor 140 operations again by display module.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 demonstration and normal demonstration the under the rotational speed monitor, preferably, do a simple differential display, as with degree centigrade icon flickering display.
Thus, the control that the present invention compares has in the past increased the difficulty that scm software is write, thereby can in the actual speed that does not need to record under the detecting instrument compressor operating, bring convenience to performance test.
Refrigerator according to the embodiment of the invention, increased communication byte D, trigger switch by the Macintosh mode enters the rotational speed monitor pattern, and pass to display unit by UART asynchronous communication or single line communication, thereby show the real-time rotate speed of compressor, brought convenience to performance test, thereby user or tester can not used in the instrument situation such as oscillograph, directly read the real time execution rotating speed of compressor, more humane.
