[0034] The technical scheme in this embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in this embodiment of the present invention. Obviously, the described embodiment is one embodiment of the present invention, not all embodiments of the present invention. Based on this embodiment of the present invention, all other embodiments of the present invention obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative blocking relationship, movement status, etc. between the components under a certain specific posture (as described in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0036] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

[0037] See also Figures 1 to 4 , an embodiment of the present invention provides a control method for a light-emitting knob lamp, the control method comprising:

[0038] Get the working status of the oven;

[0039] Under the corresponding working state of the oven, the gear position of each luminous knob is detected;

[0040] According to the gear position of each luminous knob, the two light sources of the corresponding luminous knob are controlled and switched.

[0041] In this embodiment, there are three working states of the oven, namely, an off state, a standby state, and an on state. The gear positions of the luminous knob include an ON gear and an OFF gear. The two light sources of the luminous knob include a first light source and a second light source. The colors of the first light source and the second light source are different. For example, the light color of the first light source is red, and the light color of the second light source is white.

[0042] The following is the control of the illuminated knob light in different working conditions:

[0043] The working state of the oven obtained is the shutdown state. In the shutdown state, the gear positions of all the light knobs are in the OFF gear, and the first light source and the second light source are both in the off state;

[0044] When it is detected that any luminous knob is turned to the ON position, the first light source of the corresponding luminous knob is turned on, and the oven enters the power-on state. At the same time, the corresponding second light sources of other luminous knobs that are in the OFF position are turned on. In this way, the first light source of the luminous knob in the ON position is lit, and the second light source of other luminous knobs in the OFF position is turned on. Through the first light source and the second light source of different colors, consumers can better distinguish the luminous knobs in different working states, which facilitates them to select different functional effects.

[0045] When the working state of the oven obtained is the power-on state, in the power-on state, at least one luminous knob of the oven is in the ON position, the first light source of the luminous knob in the ON position is turned on, and the other luminous knobs are in the OFF position, and the corresponding second light sources are turned on;

[0046] When it is detected that the luminous knob in the OFF position is turned to the ON position, the second light source is controlled to be turned off and the first light source is turned on at the same time. The other luminous knobs remain unchanged and the oven is still in the on state.

[0047] When it is detected that all the light-emitting knobs in the ON position are twisted to the OFF position, the first light source is turned off and the second light source is turned on at the same time. At this time, all the light-emitting knobs are in the OFF position and enter the standby state;

[0048] When the working state of the oven obtained is the standby state, in the standby state, the oven has just finished working, and all the light knobs are in the OFF state, all the first light sources are turned off, and the second light sources are turned on;

[0049] After entering the standby state, the light-emitting knobs are detected. When it is detected that all the light-emitting knobs are in the OFF position and are not in the shutdown state, the first timer is started to count, and the time t1 that the light-emitting knob stays in the OFF position is obtained. When t1≥t, all light sources are turned off and the shutdown state is entered, where t is a preset time threshold;

[0050] Preferably, after starting the first timer, continue to detect whether the gear position of the luminous knob changes. When t1<t, the gear position change of the luminous knob is detected, that is, before t is reached, any one or all of the luminous knobs are turned to the ON gear, then the first timer stops timing, all luminous knobs in the ON gear turn on the first light source and turn off the second light source, and other luminous knobs in the OFF gear turn on the second light source, and the oven enters the power-on state;

[0051] When no change of the light knob is detected within the preset time t, all light sources are turned off and the system enters the shutdown state.

The power supply port of the control chip MCU1, the power supply port of N knob switches HALL, the power supply port of the first light source control branch L1 on any one of the N knob switches HALL, and the power supply port of the second light source control branch L2 on any one of the N knob switches HALL are respectively connected to the DC output port of the rectifier BR1.

[0058] Rectifier BR1 is an ABS210 rectifier chip.

[0059] A linear regulator IC1 is connected between the power supply port of the control chip MCU1, the power supply ports of the N knob switches HALL, and the DC output port of the rectifier BR1.

[0060] Linear regulator IC1 is a 78M05 voltage regulator chip.

[0061] The potential signal output pin O of the N knob switches HALL, the control input pin of the first light source control branch L1 on any one of the N knob switches HALL, and the control input pin of the second light source control branch L2 on any one of the N knob switches HALL are respectively connected to the IO interface of the control chip MCU1.

[0062] The first light source control branch L1 includes a plurality of LED lamp beads connected in series and a transistor, one end of the plurality of LED lamp beads connected in series is connected to the collector pin C of the transistor, the power supply port of the first light source control branch L1 is the interface between the other end of the plurality of LED lamp beads connected in series and the emitter pin K of the transistor, and the control input pin of the first light source control branch L1 is the base pin B of the transistor.

[0063] The second light source control branch L2 includes a plurality of LED lamp beads connected in series and a transistor, one end of the plurality of LED lamp beads connected in series is connected to the collector pin C of the transistor, the power supply port of the second light source control branch L2 is the interface between the other end of the plurality of LED lamp beads connected in series and the emitter pin K of the transistor, and the control input pin of the second light source control branch L2 is the base pin B of the transistor.

[0064] The N rotary switch HALLs are potentiometers respectively, and the power supply port of any one of the N rotary switch HALLs is an interface between the positive fixed end pin V and the negative fixed end pin G of the rotary switch HALL.

[0065] A filter capacitor is connected between the positive fixed end pin V and the negative fixed end pin G of any one of the N knob switches HALL, and the filter capacitor plays a role in stabilizing the signal of the potential signal output pin O of the knob switch HALL.

[0066] The power supply port of the control chip MCU1 is an interface between a VDD pin and a VSS pin of the control chip MCU1.

[0067] The working principle of the above control circuit is:

[0068] S0: A control circuit of a light-emitting knob lamp in an embodiment of the present invention is specifically applied to an electric oven, wherein the control chip MCU1 is installed on a circuit integrated board inside the electric oven, and the knob switch HALL is installed on a mounting panel on a side wall of the electric oven. The inner cavity of any knob switch HALL is sequentially surrounded by a plurality of LED lamp beads connected in series of a first light source control branch L1 and a plurality of LED lamp beads connected in series of a second light source control branch L2. The electric oven has three working states, namely: working state, standby state and shutdown state. The knob switch HALL has two gears, namely, ON gear and OFF gear.

[0069] If the control chip MCU1 detects that at least one knob switch HALL is in the ON position, it is determined to be in the working state.

[0070] When all the knob switches HALL are turned to OFF, the control chip MCU1 is first determined to be in standby state, and then the control chip MCU1 is in countdown state. If any knob switch HALL is turned to ON during the countdown, the control chip MCU1 is determined to be in working state. Otherwise, the countdown ends and the control chip MCU1 is determined to end the working state.

[0071] S1: When at least one knob switch HALL is in the ON position, the control chip MCU1 determines that it is in the working state. At this time, the knob switch HALL in the ON position sends the first control signal to the control chip MCU1 through its control input pin. After receiving the first control signal, the control chip MCU1 controls the first light source control branch L1 corresponding to the knob switch HALL to turn on through the control input pin of the first light source control branch L1. Several LED lamp beads connected in series on the first light source control branch L1 show white light, so that the user can know that the knob switch HALL is in the working state.

[0072] When other knob switches HALL are in the OFF position, the knob switch HALL in the OFF position sends the second control signal to the control chip MCU1 through its control input pin. After receiving the second control signal, the control chip MCU1 controls the second light source control branch L2 corresponding to the knob switch HALL to turn on through the control input pin of the second light source control branch L2. Several LED lamp beads connected in series on the second light source control branch L2 light up red, so that the user can know that the knob switch HALL is in an inoperative state.

[0073] S2: When the gear of all the knob switches HALL is changed to OFF gear, the control chip MCU1 is first determined to be in standby state. At this time, the control chip MCU1 will be in countdown state. In the countdown state, all the knob switches HALL in OFF gear send the second control signal to the control chip MCU1 through its control input pin. After receiving the second control signal, the control chip MCU1 controls the second light source control branch L2 corresponding to the knob switch HALL to turn on through the control input pin of the second light source control branch L2. Several LED lamp beads connected in series on the second light source control branch L2 are red, so that the user can know that all the knob switches HALL are in standby state.

[0074] If in the countdown state, any knob switch HALL is adjusted to the ON position, the control chip MCU1 determines that it is in the working state, and jumps to step S1;

[0075] If the countdown is over, the control chip MCU1 determines that the working state has ended. At this time, the control chip MCU1 disconnects the control of all the first light source control branch L1 and the second light source control branch L2, so that several series-connected LED lamp beads on the first light source control branch L1 and several series-connected LED lamp beads on the second light source control branch L2 are all off, so that the user can know that all the knob switches HALL are in the off state.

[0076] A computer-readable storage medium stores a computer program, which, when executed by a processor, enables the processor to execute the above-mentioned control method for a light-emitting knob lamp.
