Embodiment 1

[0037] According to an embodiment of the present invention, an embodiment of an LED control method is provided. It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and, although A logical order is shown in the flowcharts, but in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0038] figure 2 is a flow chart of an LED control method according to an embodiment of the present invention, such as figure 2 As shown, the method includes the following steps:

[0039] Step S202, obtaining a plurality of LEDs to be controlled, wherein the plurality of LEDs to be controlled need to be controlled simultaneously.

[0040] Specifically, such as figure 1 As shown, the aforementioned plurality of LEDs to be controlled may be any number of LED1 to LED16, for example, may be LED1-LED8.

[0041] Step...

Embodiment 2

[0074] According to an embodiment of the present invention, an embodiment of an LED control system is provided.

[0075] image 3 is a schematic diagram of an LED control system according to an embodiment of the present invention, such as image 3 As shown, the system includes: a plurality of LEDs 32 to be controlled and a control device 34 .

[0076] Wherein, the control device is connected to a plurality of LEDs to be controlled, and is used to control the lighting time of the plurality of LEDs to be controlled to be different, so as to reduce the instantaneous maximum current of the circuit.

[0077] Specifically, such as figure 1 As shown, the aforementioned plurality of LEDs to be controlled may be any number of LED1 to LED16, for example, may be LED1-LED8. By changing the lighting time and order of the LEDs, the lighting time of multiple LEDs to be controlled is staggered, thereby reducing the number of LEDs that are lit at the same time, and reducing the instantaneou...

Embodiment 3

[0089] According to an embodiment of the present invention, an embodiment of a cooking appliance is provided, including: the LED control system in Embodiment 2 above.

[0090] Optionally, the above-mentioned cooking appliance is an electric pressure cooker.

[0091] Specifically, the above-mentioned cooking appliance may be an appliance such as an electric pressure cooker, an electric rice cooker, or a cooking machine that needs to display and control LEDs. In the embodiment of the present invention, an electric pressure cooker is used as an example for illustration.

Abstract

The invention discloses an LED control method and system and a cooking utensil. The method comprises the following steps: acquiring a plurality of LEDs to be controlled, wherein the LEDs to be controlled need to be controlled at the same time; and controlling the lightening time of the plurality of LEDs to be controlled to be not completely the same so as to reduce the instantaneous highest current of a line. The technical problem that in the prior art, when multiple LEDs are controlled to be lightened at the same time, the instantaneous current of a circuit is high is solved.

Description

technical field [0001] The invention relates to the field of household electrical appliances, in particular to an LED control method and system, and improvements to cooking utensils. Background technique [0002] Existing cooking utensils, such as electric pressure cookers, LED displays include constant on, off, or display with effects such as breathing lights, while some electric pressure cooker LEDs need to display full brightness, no brightness, or half brightness (or other brightness), such as , for the hidden menu, when the function cannot be selected, the LED is off, when the function can be selected, the LED is half bright (or other brightness), when the function is selected, the LED is fully bright. [0003] like figure 1 As shown, assume that there are 16 LEDs, each group of 8 LEDs, a total of two groups, SEG_LED1 ~ SEG_LED8, and COM1_LED ~ COM2_LED are respectively connected to different pins of the main control chip. by figure 1 As an example, the following ins...
