[0056] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the present application will be described clearly and completely below in combination with the drawings. Obviously, the described embodiments are some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0057] In order to facilitate the understanding of the present embodiment, the application scenario and design idea of the present embodiment are introduced briefly as follows.

[0058] The oil fume collector is limited by its own operation limit in actual operation, and the oil fume absorption and purification effect is limited, and the prior art does not provide a control method capable of automatically adjusting the oil fume absorption and purification effect of the oil fume collector.

[0059] Based on this, the present embodiment provides an oil fume collector control method, device and system, which is applied to a control unit in an oil fume collector control system.

[0060] Embodiment 1

[0061] The present application provides an oil fume collector control method, which combines Figure 1 As shown in the figure, the method comprises:

[0062] S110, in the cooking process, the current temperature of each cooking area is acquired.

[0063] S120, in combination with all the current temperatures, the target cooking area that is performing a cooking task is determined.

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

[0065] In the present application, the target cooking area that is currently cooking and the target air supplement device to be adjusted are determined based on the current temperature of each cooking area, and then the target air supplement device is adjusted based on the number of target cooking areas, so as to adjust the air intake amount for different cooking conditions, thereby improving the oil fume purification effect.

[0066] Among them, the cooking area refers to the area used for cooking corresponding to the smoke collecting port 11 (in combination with Figure 3 The cooking area is usually divided into multiple cooking areas according to the number of middle burners of the cooking appliance, and fire can be ignited and cooking can be performed in each cooking area. Usually, there is one or two cooking areas. It can be understood that the current temperature of the cooking area is detected by a temperature sensing component, which can be arranged in the kitchen space close to the cooking area, or can be arranged on the cooking appliance 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 a cooking task is taken as the target cooking area. It can be understood that the temperature threshold corresponding to different detection methods is different, which can be adjusted according to the actual situation. The temperature sensing component is in communication connection with the control unit.

[0067] In combination with the first aspect, the cooking area has two. In combination with Figure 4As shown, the smoke exhaust hood has a smoke collecting cavity 1, and a plurality of air supplementers 7 corresponding to the number of cooking areas are arranged in the smoke collecting cavity 1. The air supplementers 7 are movable along a moving track 8 arranged in the smoke collecting cavity 1. It can be understood that the air supplementers 7 are slidably connected with the moving track 8 through a connecting member, and the connecting member is connected with a driving assembly. The driving assembly drives the connecting member to slide along the moving track 8, so as to drive the air supplementers 7 to move.

[0068] Step S130 comprises:

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

[0070] If not, steps S132-S133 are executed; if yes, step S134 is executed.

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

[0072] S133, controlling the target air supplementers to run after moving to the target position.

[0073] S134, controlling two air supplementers to run after moving to the target positions corresponding to the positions of the two target cooking areas.

[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 one. If the number is greater than one, it means that there are two target cooking areas, i.e., all cooking areas are performing cooking tasks. At this time, step S134 is executed to correspond two air supplementers to two target cooking areas respectively, and to capture and purify the oil fume of the two cooking areas. In step S132, if the number is not greater than one, and at this time the cooking process is in progress, it means that there is one target cooking area, i.e., one cooking area is performing a cooking task. At this time, the cooking area performing the cooking task is taken as the target cooking area, and the position corresponding to the position of the target cooking area is taken as the target position. Then, the air supplementer having a position deviation from the target position is taken as the target air supplementer. After that, the target air supplementer is controlled to run after moving to the target position, so that the two target air supplementers correspond to the target cooking area, and the ability to capture and purify the oil fume of the target cooking area is improved.

[0075] Example 2

[0076] The application provides another range hood control method, which is applied to a control unit in a range hood control system. A plurality of air supplementers 7 corresponding to the number of cooking areas are arranged in a smoke collecting cavity 1 in the range hood control system, and the air supplementers 7 can move in the smoke collecting cavity 1. The range hood control system further comprises a temperature sensing assembly and an environmental parameter detection assembly. Different environmental parameter detection assemblies correspond to different types of environmental parameters. In this embodiment, the environmental parameters at least include a PM value, and the corresponding environmental parameter detection assembly at least includes a PM sensor which is in communication connection with the control unit. The PM value refers to the concentration of particulate matter in the air. For example, when the concentration (i.e. the PM value) of fine particulate matter with a diameter less than or equal to 2.5 microns in the air is 35-75ug / m 3 , it belongs to light pollution; when the concentration is 75-115ug / m 3 , it belongs to moderate pollution; when the concentration is 115-150ug / m 3 , it belongs to heavy pollution; and when the concentration is greater than 150ug / m 3 , it belongs to serious pollution.

[0077] As shown in Figure 2 , in this embodiment, the outlet end of the smoke collecting cavity 1 is connected to a fan assembly 3 through an air flow pipeline 2. A plurality of air inlets 4 are arranged on the outer side of the air flow pipeline 2 along the height direction. The air inlets 4 are connected to high-pressure air inlet devices 5 arranged on the smoke collecting cavity 1. The outlets of the air inlets 4 are in communication with the air flow pipeline 2 through conveying pipelines 6 to convey high-pressure gas to the air flow pipeline 2.

[0078] As shown in Figure 5 , the method comprises the following steps.

[0079] In S210, the current temperature of each cooking area is obtained during cooking.

[0080] In S220, the target cooking area performing a cooking task is determined in combination with all the current temperatures.

[0081] In S230, the target air supplementer is controlled to move to a target position and then run according to the number and position of the target cooking area.

[0082] In S240, a first environmental parameter during the running of the target air supplementer is obtained, and the first environmental parameter at least includes a first PM value.

[0083] In S250, it is judged whether the first PM value is greater than a preset PM threshold value.

[0084] If yes, S260 is performed. If no, S270 is performed.

[0085] S260, turn on an air inlet device connected with the pipeline of the range hood.

[0086] S270, keep the current running state.

[0087] In the cooking process, adjusting the position of the target air supplement device and starting the target air supplement device based on the number and position of the target cooking area can improve the oil fume purification effect for the target cooking area. Then, the PM value during the operation of the target air supplement device is collected. If the PM value is greater than the preset PM threshold value, it indicates that the target cooking area has a smoke running phenomenon, i.e., the oil fume purification does not meet the requirements. At this time, an air inlet device 4 connected with the pipeline of the range hood is turned on to further improve the oil fume capturing effect. It can be understood that if the first PM value is less than or equal to the PM threshold value, it indicates that the target cooking area does not have a smoke running phenomenon. At this time, the current running state can be kept.

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

[0089] S270, after a preset time length, a second environmental parameter is acquired.

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

[0091] If not, step S291 is executed, and if yes, step S292 is executed.

[0092] S291, an air inlet device is turned off.

[0093] S292, an air inlet device is turned on one by one until a third PM value in a third environmental parameter is less than the PM threshold value, or all air inlet devices are turned on.

[0094] That is, after the first newly added air inlet device 4 runs for t time, the PM value is acquired again. If the PM value is still greater than the PM threshold value, it indicates that the oil fume purification effect has not been effectively improved, i.e., the improvement effect is not obvious. At this time, another air inlet device 4 is turned on and the detection process is repeated until the oil fume purification effect meeting the requirements is obtained, or all air inlet devices 4 are turned on. If it is determined that the expected oil fume purification effect is reached after the PM detection, an air inlet device 4 can be turned off to reduce power consumption, which is conducive to energy saving.

[0095] In combination with the first aspect, after step S292, the method further includes:

[0096] S293, a fourth environmental parameter is acquired.

[0097] S294, if a fourth PM value in the fourth environmental parameter is still greater than the PM threshold value, the running power of the air inlet device is increased.

[0098] In the case that all the air inlets 4 are opened, the limit oil fume purification effect that can be achieved under the current operation power has been obtained, and the PM value is detected again. If the PM value is still greater than the PM threshold value, that is, the expected requirement is still not met, the operation power of the air inlets 4 is increased to improve the operation limit and the oil fume purification effect.

[0099] In a second aspect, the present application provides an oil fume extractor control device, which is combined with Figure 6 As shown in the figure, the device comprises an acquisition module 10, a determination module 20 and a control module 30.

[0100] The acquisition module 10 is configured to acquire the current temperature of each cooking area during cooking.

[0101] The determination module 20 is configured to determine the target cooking area that is performing a cooking task in combination with all the current temperatures.

[0102] The control module 30 is configured to control the target air inlet 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 an oil fume extractor control system, which comprises an oil fume extractor body, air inlets 4, a temperature detection assembly and a control unit.

[0104] The oil fume extractor body is combined with Figure 2 As shown in the figure, the oil fume extractor body comprises a smoke collecting cavity 1, an air flow pipeline 2 and a fan assembly 3 connected in sequence; a plurality of air inlets 4 are arranged on the outer side of the air flow pipeline 2 along the extension direction of the air flow pipeline 2 in sequence, the air inlets 4 are connected with a high-pressure air inlet device 5 through a conveying pipeline 6, and the air outlets are in communication with the air flow pipeline 2.

[0105] The air inlets 4 are combined with Figure 3 , Figure 4 As shown in the figure, the air inlets 4 are arranged in the smoke collecting cavity 1 and close to the smoke collecting port 11 of the smoke collecting cavity 1.

[0106] The temperature detection assembly is in one-to-one correspondence with the cooking areas and is configured to detect the temperature of the cooking areas.

[0107] The control unit is connected with the temperature detection assembly, and the control unit is configured to execute the method as described above.

[0108] In combination with the third aspect, the system further comprises:

[0109] The position adjustment assembly comprises a moving track 8 and a connecting piece in sliding cooperation with the moving track 8, and the connecting piece is fixedly connected with the air inlets 7.

[0110] The driving assembly is connected with the connecting piece at the output end, the driving assembly is connected with the control unit, and the driving assembly is configured to drive the connecting piece to move to adjust the position of the air inlets 7.

[0111] It can be understood that the moving track 8 in the position adjusting assembly provides a fixed path for the connecting piece, and the connecting piece can be in sliding fit with the moving track 8, that is, can freely slide on the moving track 8. At the same time, the connecting piece is fixedly connected with the air supplement device 7, and the connecting piece drives the air supplement device 7 to move linearly along the moving track 8 when the connecting piece slides on the moving track 8, so that the air supplement device 7 can be adjusted in position within a preset range. It can be understood that when the number of air supplement devices 7 is greater than 1, the number of position adjusting assemblies corresponds to the number of air supplement devices 7, and the plurality of position adjusting assemblies are arranged adjacent to each other in a direction perpendicular to the linear motion direction of the air supplement device 7. The spacing between the adjacent two position adjusting assemblies can be set according to actual conditions, which is not limited here.

[0112] In order to realize automatic control, the output end of the driving assembly is directly connected or connected through an intermediate transmission mechanism with the connecting piece. When the driving assembly receives a control instruction, it will output power, and the power is transmitted to the connecting piece through this connection mode, so as to drive the air supplement device 7 to move along the moving track 8. In addition, in order to realize accurate control of the position of the air supplement device 7, the driving assembly also needs to be connected with a control unit. The control unit can receive signals (such as temperature change, air flow demand, etc.) from the operator or other systems, and then send corresponding action instructions to the driving assembly according to these information, for example, in the actual cooking process, there are two cooking areas (cooking area A and cooking area B), and it is determined that only the cooking area A is in working state based on temperature detection. At this time, the control unit sends a control instruction, and the driving assembly outputs power in response to the control instruction to move both air supplement devices 7 to the target positions corresponding to the cooking area A and then run.
