[0056] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0057] In order to facilitate the understanding of this embodiment, the application scenarios and design concepts of the embodiments of the present application are briefly introduced below.

[0058] During actual operation, the range hood is limited by its own operating limit, and the oil fume absorption and purification effects are limited. However, the prior art does not provide a control method that can automatically adjust the oil fume absorption and purification effects of the range hood.

[0059] Based on this, an embodiment of the present application provides a range hood control method, device and system, which is applied to a control unit in a range hood control system.

[0060] Example 1

[0061] The present application provides a range hood control method, combined with Figure 1 As shown, the method includes:

[0062] S110, during the cooking process, obtaining the current temperature of each cooking zone.

[0063] S120, determining a target cooking area where the cooking task is being performed in combination with all current temperatures.

[0064] S130, according to the number and position of the target cooking area, controlling the target air supply device to move to the target position and then operate.

[0065] In the present application, the target cooking area currently being cooked and the target air supply device to be adjusted are determined based on the current temperature of each cooking area. The target air supply device is then adjusted based on the number of target cooking areas to adjust the air intake volume for different cooking situations, thereby improving the oil fume purification effect.

[0066] The cooking area refers to the smoke collecting port 11 of the range hood in the kitchen space (combined with Figure 3 The cooking area corresponding to the cooking device (as shown) is usually divided into multiple cooking areas according to the number of burners in the cooker, and you can light a fire and cook in each cooking area. Usually there are one or two cooking areas. It is understandable that the current temperature of the cooking area is detected by a temperature sensing component. The temperature sensing component can be set in a kitchen space close to the cooking area, and can also be set on the cooker body. The setting position is not limited, as long as the temperature of the cooking area can be detected. When the detected temperature is greater than the preset temperature threshold, it indicates that the cooking area is performing a cooking task, and the cooking area that is performing the cooking task is used as the target cooking area. It is understandable that different detection methods correspond to different temperature thresholds, which can be adjusted according to actual conditions. The temperature sensing component is communicatively connected to the control unit.

[0067] In combination with the first aspect, there are two cooking areas. Figure 4As shown, the smoke collecting chamber 1 of the range hood is provided with air replenishers 7 corresponding to the number of cooking zones, and the air replenishers can move along a moving track 8 provided in the smoke collecting chamber. It can be understood that the air replenisher 7 is slidably connected to the moving track 8 through a connecting member, and the connecting member is also connected to a driving assembly, and the driving assembly drives the connecting member to slide along the moving track 8, thereby driving the air replenisher 7 to move.

[0068] Step S130 includes:

[0069] S131, determining whether the number of target cooking zones is greater than one.

[0070] If not, execute steps S132-S133; if so, execute step S134.

[0071] S132, determining a target position corresponding to the position of the target cooking area, and taking all the air supply devices as target air supply devices.

[0072] S133, control the target air supply device to move to the target position and then operate.

[0073] S134, controlling the two air supply devices to move to target positions corresponding to the positions of the two target cooking areas and then operate.

[0074] After the target cooking area is determined in step S120, it is first determined whether the number of target cooking areas is greater than 1. If the number is greater than 1, it means that there are two target cooking areas, that is, all cooking areas are performing cooking tasks. At this time, step S134 is executed to correspond the two air supply devices to the two target cooking areas one by one, and the oil smoke of the two cooking areas is captured and purified respectively. In S132, if the number is not greater than 1, and the cooking process is in progress at this time, it means that there is one target cooking area, that is, one of the cooking areas is performing a cooking task. At this time, the cooking area that performs the cooking task is used as the target cooking area, and the position corresponding to the position of the target cooking area is used as the target position. After that, the air supply device with a position deviation from the target position is used as the target air supply device. After that, the target air supply device is controlled to move to the target position and then run, so that both target air supply devices correspond to the target cooking area, and the ability to capture and purify the oil smoke of the target cooking area is improved.

[0075] Example 2

[0076] The present application provides another range hood control method, which is applied to a control unit in a range hood control system, wherein a plurality of air supply devices 7 corresponding to the number of cooking areas are provided in the smoke collecting chamber 1 in the range hood control system, and the air supply devices 7 can be moved in the smoke collecting chamber 1. The range hood control system also includes a temperature sensing component and an environmental parameter detection component, wherein the environmental parameter detection components corresponding to different types of environmental parameters are also different. In the present embodiment, the environmental parameters at least include a PM value, and correspondingly, the environmental parameter detection component at least includes a PM sensor, which is also communicatively connected to the control unit. Among them, the PM value refers to the concentration of particulate matter in the air. For example, for fine particulate matter with a diameter less than or equal to 2.5 microns in the air, when its concentration (ie, the PM value) is between 35-75ug / m 3 It is considered light pollution when its concentration is 75-115ug / m 3 When the concentration is between 115-150ug / m 3 When the concentration is greater than 150ug / m 3 It is considered serious pollution.

[0077] Combination Figure 2 As shown, in the present embodiment, the outlet end of the smoke collecting chamber 1 is connected to the fan assembly 3 via the airflow pipeline 2, and a plurality of air inlets 4 are arranged along the height direction on the outside of the airflow pipeline 2, and the air inlets 4 are connected to the high-pressure air intake device 5 arranged on the smoke collecting chamber 1, and the outlet of the air inlet 4 is connected to the airflow pipeline 2 via the delivery pipe 6 to deliver high-pressure gas to the airflow pipeline 2.

[0078] Combination Figure 5 As shown, the method includes:

[0079] S210, during the cooking process, obtaining the current temperature of each cooking zone.

[0080] S220, determining a target cooking area where the cooking task is being performed in combination with all current temperatures.

[0081] S230, according to the number and position of the target cooking area, control the target air supply device to move to the target position and then operate.

[0082] S240, obtaining a first environmental parameter during the operation of the target air supply device, where the first environmental parameter at least includes a first PM value.

[0083] S250: Determine whether the first PM value is greater than a preset PM threshold.

[0084] If yes, go to step S260. If no, go to step S270.

[0085] S260, opening an air inlet connected to the range hood pipeline.

[0086] S270, maintain the current running status.

[0087] During the cooking process, adjusting the position of the target air supply device based on the number and position of the target cooking area and starting the target air supply device can improve the oil fume purification effect of the target cooking area. Then, the PM value of the target air supply device during operation is collected. If it is greater than the preset PM threshold, it means that there is smoke leakage in the target cooking area, that is, the oil fume purification does not meet the requirements. At this time, an air inlet 4 connected to the range hood pipeline is turned on to further improve the oil fume capture effect. It can be understood that if the first PM value is less than or equal to the PM threshold, it means that there is no smoke leakage in the target cooking area, and the current operating state can be maintained at this time.

[0088] In combination with the first aspect, after step S260, the method further includes:

[0089] S270, after a preset time period, obtain a second environmental parameter.

[0090] S280, determining whether the second PM value in the second environmental parameter is still greater than the PM threshold.

[0091] If not, execute step S291, and if so, execute step S292.

[0092] S291, close an air inlet.

[0093] S292, opening one air inlet at a time until the third PM value in the third environmental parameter is less than the PM threshold, or opening all air inlets.

[0094] That is, after the first addition of an air inlet 4 for operation for t time, the PM value is obtained again. If it is still greater than the PM threshold, it means that the oil fume purification effect has not been effectively improved, that is, the improvement effect is not obvious. At this time, another air inlet 4 is turned on and the detection process is repeated until the oil fume purification effect that meets the requirements is obtained, or all air inlets 4 are turned on. If it is determined after the PM detection that the expected oil fume purification effect has been achieved, one air inlet 4 can be turned off to reduce power loss, which is beneficial to energy saving.

[0095] In combination with the first aspect, step S292 opens one air inlet at a time until all the air inlets are opened, and further includes:

[0096] S293, obtaining a fourth environmental parameter.

[0097] S294: If the fourth PM value in the fourth environmental parameter is still greater than the PM threshold, increase the operating power of the air inlet.

[0098] When all the air inlets 4 are turned on, the maximum oil fume purification effect that can be achieved under the current operating power has been obtained. At this time, the PM value is detected again. If it is still greater than the PM threshold, it means that the expected requirements are still not met. At this time, the operating power of the air inlet 4 is increased to increase the operating limit and improve the oil fume purification effect.

[0099] In a second aspect, the present application provides a range hood control device, Figure 6 As shown, the device includes: an acquisition module 10, a determination module 20 and a control module 30.

[0100] The acquisition module 10 is used to acquire the current temperature of each cooking zone during the cooking process.

[0101] The determination module 20 is used to determine the target cooking zone where the cooking task is being performed, based on all current temperatures.

[0102] The control module 30 is used to control the target air supply device to move to the target position and then operate according to the number and position of the target cooking area.

[0103] In a third aspect, the present application provides a range hood control system, which includes: a range hood body, an air inlet 4, a temperature detection component and a control unit.

[0104] Range hood body, combined Figure 2 As shown, the range hood body includes a smoke collecting chamber 1, an airflow pipeline 2 and a fan assembly 3 which are connected in sequence; a plurality of air inlets 4 are arranged in sequence on the outside of the airflow pipeline 2 along the extension direction of the airflow pipeline 2, and the air inlets of the plurality of air inlets 4 are respectively connected to the high-pressure air intake device 5 through the conveying pipe 6, and the air outlets are connected to the airflow pipeline 2.

[0105] Combination Figure 3 , Figure 4 As shown, the air replenisher 7 is arranged in the smoke collecting chamber 1 and close to the smoke collecting port 11 of the smoke collecting chamber 1 .

[0106] The temperature detection component corresponds to each cooking area one by one and is used to detect the temperature of the cooking area.

[0107] A control unit is connected to the temperature detection component, and the control unit is used to execute the above method.

[0108] In conjunction with the third aspect, the system further includes:

[0109] The position adjustment component includes a movable track 8 and a connecting piece that slidably cooperates with the movable track 8, and the connecting piece is fixedly connected to the air replenisher 7.

[0110] The drive component has an output end connected to the connecting piece, and the drive component is connected to the control unit, and is used to drive the connecting piece to move to adjust the position of the air replenisher 7.

[0111] It is understandable that the moving track 8 in the position adjustment assembly provides a fixed path for the connector, and the connector can slide with the moving track 8, that is, it can slide freely on the moving track 8. At the same time, the connector is fixedly connected to the air replenisher 7, and when the connector slides on the moving track 8, it drives the air replenisher 7 to move linearly along the moving track 8, so that the air replenisher 7 can be adjusted in position within a preset range. It is understandable that when the number of air replenishers 7 is greater than 1, the number of position adjustment assemblies corresponds to the number of air replenishers 7, and multiple position adjustment assemblies are adjacently arranged along a direction perpendicular to the linear movement direction of the air replenisher 7, and the spacing between two adjacent position adjustment assemblies can be set according to actual conditions, which is not limited here.

[0112] In order to realize automatic control, the embodiment of the present application connects the output end of the driving component to the connecting member directly or through an intermediate transmission mechanism. When the driving component receives a control instruction, it will output power, and transmit the power to the connecting member through this connection method, thereby driving the air replenisher 7 to move along the movable track 8. In addition, in order to realize precise control of the position of the air replenisher 7, the driving component also needs to be connected to a control unit. The control unit can receive signals from the operator or other systems (such as temperature changes, airflow requirements, etc.), and then send corresponding action instructions to the driving component based on this information. For example, in the actual cooking process, there are two cooking areas (cooking area A and cooking area B). Based on temperature detection, it is determined that only cooking area A is in working state. At this time, the control unit sends a control instruction, and the driving component responds to the control instruction to output power to move both air replenishers 7 to the target position corresponding to cooking area A and then operate.

[0113] In a fourth aspect, an embodiment of the present application provides an electronic device, Figure 7 As shown, the electronic device includes a memory 131 and a processor 130. The memory 131 is used to store computer programs, and the processor 130 runs the computer programs to enable the electronic device to perform the above method.

[0114] Furthermore, combined with Figure 7 The electronic device shown further includes a bus 132 and a communication interface 133 , and the processor 130 , the communication interface 133 and the memory 131 are connected via the bus 132 .

[0115] The memory 131 may include a high-speed random access memory (RAM), and may also include a non-volatile memory, such as at least one disk storage. The communication connection between the system network element and at least one other network element is realized through at least one communication interface 133 (which may be wired or wireless), and the Internet, wide area network, local area network, metropolitan area network, etc. may be used. The bus 132 may be an ISA bus, a PCI bus, or an EISA bus, etc. The bus can be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Figure 7 Only one bidirectional arrow is used in the diagram, but this does not mean that there is only one bus or only one type of bus.

[0116] The processor 130 may be an integrated circuit chip with signal processing capabilities. In the implementation process, each step of the above method can be completed by the hardware integrated logic circuit or software instructions in the processor 130. The above processor 130 can be a general-purpose processor, including a central processing unit (CPU), a network processor (NP), etc.; it can also be a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components.
