Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Fig. 1 shows the realization flow of the dish-washing machine stand-by power consumption control method that the embodiment of the present invention provides, and for convenience of explanation, illustrate only part related to the present invention, details are as follows:
In step sl, after dish-washing machine powers on, judge whether power button is pressed, and is, then perform step S2, no, then perform step S4.
In step s 2, the power supply output to the signal deteching circuit in dish-washing machine and display circuit is opened.
Wherein, step S2 is specially: export the direct current that the direct supply of dish-washing machine exports to signal deteching circuit and display circuit.
In step s3, in dish-washing machine operational process, carry out timing, and judge whether the lighting time of the display of dish-washing machine is greater than prefixed time interval, is, then perform step S4, no, then perform step S2.
In step s 4 which, the power supply output to the signal deteching circuit in dish-washing machine and display circuit is turned off.
Wherein, step S4 is specially: stop exporting the direct current that the direct supply of dish-washing machine exports to signal deteching circuit and display circuit.
Below in conjunction with example, above-mentioned dish-washing machine stand-by power consumption control method is described further:
After the power-up, dish-washing machine enters holding state, if power button is not pressed, then the direct current that direct supply exports is not exported to the signal deteching circuit in dish-washing machine and display circuit, so signal deteching circuit and display circuit cannot work on power, and then reduce the stand-by power consumption of dish-washing machine; If power button is pressed, then export direct current to the signal deteching circuit in dish-washing machine and display circuit, signal deteching circuit and display circuit work on power.
Realize in the process of operation at dish-washing machine according to the setting of user, if the lighting time of display is greater than prefixed time interval (as 3 minutes), then show that dish-washing machine enters holding state, so stop exporting direct current, to reduce power consumption to the signal deteching circuit in dish-washing machine and display circuit; If the lighting time of display is not more than prefixed time interval (as 3 minutes), then show that dish-washing machine is also in operational process, so continue to export direct current to signal deteching circuit and display circuit, with ensure signal deteching circuit and display circuit normal electric work.
Fig. 2 shows the structure of the dish-washing machine stand-by power consumption control device that the embodiment of the present invention provides, and for convenience of explanation, illustrate only part related to the present invention, details are as follows:
Dish-washing machine stand-by power consumption control device comprises:
Start judge module 100, for judging after dish-washing machine powers on whether power button is pressed;
Time judgment module 200, for carrying out timing in dish-washing machine operational process, and judges whether the lighting time of the display of dish-washing machine is greater than prefixed time interval;
Power supply output control module 300, for when start the judged result of judge module 100 be or the judged result of time judgment module 200 is no time, open and the power supply of the signal deteching circuit in dish-washing machine and display circuit is exported, when to start the judged result of judge module 100 be no or the judged result of time judgment module 200 for being time, turn off and the power supply of the signal deteching circuit in dish-washing machine and display circuit exported.
Wherein, power supply output control module 300 is opened and is exported the power supply of signal deteching circuit in dish-washing machine and display circuit, specifically exports the direct current that the direct supply of dish-washing machine exports to signal deteching circuit and display circuit; And power supply output control module 300 turns off the power supply output to the signal deteching circuit in dish-washing machine and display circuit, specifically stop exporting the direct current that the direct supply of dish-washing machine exports to signal deteching circuit and display circuit.
In actual application, as shown in Figure 3, startup judge module 100 and time judgment module 200 can be integrated in a single-chip microcomputer 10, this single-chip microcomputer 10 can be the model that NEC Corporation produces is the single-chip microcomputer of μ PD78F9234 or μ PD78F0511, be connected with the output delivery outlet of single-chip microcomputer 10 respectively by resistance by one or more power supply output control module 300, and each power supply output control module 300 can be used for driving one or more signal deteching circuit 30 or one or more display circuit 40, all from the direct supply 20(dish-washing machine, it can be AC/DC changeover switch to each power supply output control module 300) obtain direct current (as 5V high level), when direct supply 20 is AC/DC changeover switch, its positive input terminal+with live wire end L and the zero line side N of negative input end-be connected respectively electrical network, and between the positive input terminal+and live wire end L of direct supply 20, can be accessed by a fuse F1 to realize electrical network overvoltage protection to dish-washing machine.When dish-washing machine is in holding state, Opportunity awaiting control for linear signal (as low level) is exported through resistance (R1 ~ Rn) to power supply output control module 300 by single-chip microcomputer 10, stop making power supply output control module 300 direct current (as 5V high level) exported by direct supply 20 to export signal deteching circuit 30 and display circuit 40 to, thus reach the object reducing stand-by power consumption; And when dish-washing machine is in normal operating condition, then single-chip microcomputer 10 exports and runs control signal (as high level) through resistance (R1 ~ Rn) to power supply output control module 300, export signal deteching circuit 30 and display circuit 40 to the direct current making power supply output control module 300 be exported by direct supply 20 (as 5V high level), then signal deteching circuit 30 and display circuit 40 perform corresponding work according to the control signal that single-chip microcomputer 10 exports.
The embodiment of the present invention is by judging after dish-washing machine powers on whether power button is pressed, if, then show dish-washing machine startup work, so open, the power supply of the signal deteching circuit in dish-washing machine and display circuit is exported, if not, then show that dish-washing machine is in holding state, so turn off, the power supply of the signal deteching circuit in dish-washing machine and display circuit is exported, and in dish-washing machine operational process, the lighting time of display is judged, if lighting time exceedes prefixed time interval, show that dish-washing machine enters holding state, then turn off and the power supply of the signal deteching circuit in dish-washing machine and display circuit is exported, thus the shutoff control achieved when dish-washing machine is standby signal deteching circuit and display circuit, to reach the object effectively reducing dish-washing machine stand-by power consumption, the stand-by power consumption of dish-washing machine can be made to meet the requirement of industry power consumption standard, solve prior art existence and cannot reduce the stand-by power consumption of dish-washing machine to meet the problem of industry power consumption standard.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
