[0071] Figure 1 This is an application scenario diagram of the kitchen appliance linkage control method provided by the present invention. Figure 1 As shown, the kitchen appliance linkage control method provided in this embodiment is applied to a kitchen appliance linkage control system, wherein the kitchen appliance linkage control system may include only two kitchen appliances or multiple kitchen appliances. In this embodiment, two kitchen appliances are used as an example. Figure 1 The kitchen appliance linkage control system may include a kitchen appliance 2 and a smoke extractor 1. The communication connection between the kitchen appliance 2 and the smoke extractor 1 may be wired or wireless. The wireless connection may be any of WiFi, Bluetooth, or 433 RF, which is not specifically limited in this embodiment. It is worth noting that the kitchen appliance 2 may be any household appliance that generates fumes or steam during operation, such as an electric oven, microwave oven, electric griddle, grill, steamer, or electric hot pot. The smoke extractor 1, for example, may be a range hood or exhaust fan that extracts fumes or steam from the room during operation and discharges them outdoors.

[0072] Figure 2 FIG. 1 is a signaling interaction diagram of a kitchen appliance linkage control method according to an exemplary embodiment of the present invention. Figure 2 As shown, the kitchen appliance linkage control method provided in this embodiment includes:

[0073] S101: Obtain a door opening signal of a kitchen appliance.

[0074] Specifically, when the operating door of the kitchen appliance is opened, the door opening detection module can acquire a door opening signal. For example, if the kitchen appliance is an oven, a sensor can be provided on the oven door or the oven housing to detect the door opening state. After acquiring the door opening signal of the kitchen appliance, the door opening signal can also be fed back to the first controller of the kitchen appliance.

[0075] S102: Generate and send a trigger instruction according to the door opening signal.

[0076] When the first controller in the kitchen appliance receives the door opening signal, it generates a trigger instruction according to the door opening signal and controls the first wireless communication module in the kitchen appliance to send the trigger instruction to the connected smoking appliance.

[0077] S103: Work according to the trigger instruction.

[0078] After the second wireless communication module in the smoke extraction appliance receives the trigger instruction sent by the kitchen appliance, it operates according to the trigger instruction to extract the oil smoke and / or steam generated when the kitchen appliance is in operation.

[0079] Among them, when the smoke extraction device is a range hood, when the second wireless communication module in the range hood receives the trigger signal sent by the oven, it will feed back the trigger signal to the second controller in the range hood, so that the second controller controls the fan system of the range hood to operate to absorb the oil smoke and / or steam generated when the kitchen appliance is working.

[0080] Optionally, when the operating door of the kitchen appliance is closed, the kitchen appliance may also send a stop instruction to the smoke extraction appliance by detecting a door closing signal, so that the fan system of the smoke extraction appliance stops working.

[0081] Furthermore, to conserve energy and prevent the linked smoke extraction appliance from operating unnecessarily when the kitchen appliance's door is opened while it's not operating, the operating state of the kitchen appliance can be determined to be operational. If the operating state of the kitchen appliance is determined to be operational, the linked smoke extraction appliance will be triggered to operate upon receiving a door-opening signal. If the operating state of the kitchen appliance is determined to be inoperative, the linked smoke extraction appliance will not be triggered upon receiving a door-opening signal. It should be understood that the operating state of the kitchen appliance can be one that generates fumes and / or steam during heating, such as when an oven is grilling.

[0082] In this embodiment, by first obtaining the door opening signal of the kitchen appliance, and then generating and sending a trigger instruction based on the door opening signal, the smoke extraction appliance operates according to the received trigger instruction to extract the oil smoke and / or steam generated when the kitchen appliance is working, and discharge the oil smoke and / or steam to the outside, thereby realizing intelligent linkage between appliances, greatly improving the convenience of users in operating multiple appliances in the kitchen scene.

[0083] In order to explain in detail the technical effects of the kitchen appliance linkage control method provided by this embodiment, an example can be given in conjunction with a specific scenario in which a user uses the kitchen appliance:

[0084] When baking, users' fingers can easily come into contact with media such as cooking oil, flour, and water, and the operation often requires both hands. However, most current range hood controls on the market use keyboard switches or touch buttons. Using stained fingers to manipulate the smoke inevitably stains the surface of the range hood. Furthermore, using the range hood with both hands is even more inconvenient. By utilizing the kitchen appliance linkage control method provided in this embodiment to establish an intelligent linkage between the oven and the range hood, when the user turns on the oven, the range hood is automatically triggered to extract the smoke from the oven and discharge it outdoors, improving user convenience.

[0085] Figure 3 FIG. 1 is a signaling interaction diagram of a kitchen appliance linkage control method according to another exemplary embodiment of the present invention. Figure 3 As shown, the kitchen appliance linkage control method provided in this embodiment includes:

[0086] S201: Obtain a door opening signal of a kitchen appliance.

[0087] S202: Generate and send a trigger instruction according to the door opening signal.

[0088] S203: Work according to the trigger instruction.

[0089] It is worth noting that the specific implementation of S201-S203 in the kitchen appliance linkage control method provided in this embodiment can refer to Figure 2 The description of steps S101-S103 in the illustrated embodiment will not be repeated here.

[0090] S204: Determine whether the current smoke concentration in the air is greater than a preset safety concentration.

[0091] In order to further improve the safety of kitchen appliances, when the smoke extraction appliance is working, the smoke concentration detection module can also monitor the current smoke concentration in the air in real time or at time intervals. When the smoke concentration in the current air is detected to be greater than the preset safety concentration, it is considered that the kitchen appliance has been overheated, for example, the oven has burnt the food.

[0092] S205: Generate and send a heating stop instruction.

[0093] After detecting that the current smoke concentration in the air is greater than the preset safety concentration, a stop heating instruction can also be generated and sent to the kitchen appliances.

[0094] S206: The kitchen appliance switches the working state to the stopped operation state according to the stop heating instruction.

[0095] When the kitchen appliance receives a stop heating instruction, the first controller in the kitchen appliance switches the working state of the kitchen appliance to a stop operation state.

[0096] For example, when the range hood detects that the concentration of oil smoke in the air is greater than the preset safety concentration, it can send a stop heating instruction to the oven that is linked with it, thereby stopping the oven from continuing to heat and avoiding safety accidents caused by overheating.
