[0027] Unless otherwise specified, the term "a plurality of" means two or more.

[0028] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0029] In combination Figures 1-6 As shown, the present disclosure provides an oil fume exhaust fan, which comprises a fan part 200, a side suction part 300 and a driving device 400. The fan part 200 comprises a negative pressure cavity 201 and a fan 202 arranged in the negative pressure cavity 201; the side suction part 300 is slidably connected with the negative pressure cavity 201 and is arranged to be extendable or retractable into the negative pressure cavity 201, and a side surface of the side suction part 300 is provided with an air inlet 301 penetrating through the side surface along the extension direction of the side surface; the driving device 400 is arranged between the inner wall of the negative pressure cavity 201 and the side suction part 300 and is configured to drive the side suction part 300 to extend or retract into the negative pressure cavity 201.

[0030] The range hood provided by the embodiment of the present disclosure is provided with a telescopic side suction part 300, the distance between the side suction part 300 and the cooking bench is controllable, the side suction part 300 is provided with an air inlet, the more the side suction part 300 extends, the smaller the distance between the side suction part 300 and the cooking bench, and the more the air inlet is exposed, so that more oil fume can be sucked, the adjustability of the range hood is improved, and the smoke exhaust efficiency of the range hood is optimized.

[0031] Optionally, the fan 202 is a centrifugal fan. In this way, the centrifugal fan can increase the negative pressure in the negative pressure cavity 201, and the oil fume suction efficiency is improved.

[0032] Optionally, the air inlet of the centrifugal fan faces one end of the side suction part 300, and the air outlet is communicated with the outside of the negative pressure cavity 201 through the upper side of the negative pressure cavity 201. In this way, the air inlet of the centrifugal fan is opposite to the side suction part 300, which is beneficial to the suction of the oil fume in the side suction part 300 into the centrifugal fan, and the oil fume suction efficiency is improved.

[0033] Optionally, the side suction part 300 is vertically arranged. In this way, the vertical arrangement of the side suction part 300 facilitates the telescopic movement of the side suction part 300 in the vertical direction, so that the lower end of the side suction part 300 can be closer to the cooking bench, and the oil fume can be better absorbed, and the space occupation is smaller when the side suction part 300 is vertically arranged.

[0034] Optionally, the lower side of the side suction part 300 is provided with an oil collecting groove 302. In this way, the oil stains flowing down the side suction part 300 can be collected.

[0035] Optionally, the side surface where the air inlet 301 is located has an included angle with the vertical surface. In this way, since the oil fume is generated on the lower side of the air inlet 301, the included angle between the side surface where the air inlet 301 is located and the vertical surface is beneficial to the collection of the oil fume.

[0036] Optionally, the included angle is greater than or equal to 5 degrees and less than or equal to 15 degrees. In this way, the included angle is set to be between 5 degrees and 15 degrees, so that the angle of the air inlet 301 is kept within a reasonable range, the oil fume can be better absorbed, and the oil fume absorption capacity is improved.

[0037] Optionally, the included angle is 10 degrees. In this way, the included angle between the side surface where the air inlet 301 is located and the vertical surface is 10 degrees, the oil fume on the lower side can be better absorbed, and the oil fume absorption capacity is improved.

[0038] Optionally, the negative pressure cavity 201 is provided with a movable opening 203, and the side suction part 300 is arranged to extend out of or retract into the negative pressure cavity 201 through the movable opening 203. In this way, the side suction part 300 retracts into the negative pressure cavity 201 through the movable opening 203, so that the side suction part 300 and the inside of the negative pressure cavity 201 are always communicated, and the oil fume can be easily absorbed through the side suction part 300.

[0039] Optionally, the movable opening 203 is arranged at the bottom of the negative pressure cavity 201. In this way, the side suction part 300 can be telescoped at the bottom of the negative pressure cavity 201, so that the side suction part 300 is closer to the cooking table, i.e. the position where the oil fume is generated, thereby improving the oil fume absorption efficiency.

[0040] Optionally, the periphery of the movable opening 203 is provided with a sealing member. In this way, the sealing property between the side suction part 300 and the negative pressure cavity 201 can be improved.

[0041] Optionally, the sealing member is a rubber gasket. In this way, the rubber gasket has simple structure, low cost and good sealing effect.

[0042] Optionally, the side of the movable opening 203 in contact with the air inlet 301 is provided with a baffle 204. In this way, the airflow passing through the air inlet 301 is guided upward by the baffle 204, thereby improving the oil fume absorption capacity of the air inlet 301 and further improving the oil fume absorption efficiency.

[0043] Optionally, the baffle 204 has the same inclination angle as the side surface on which the air inlet 301 is located. In this way, the airflow is guided along the inclination direction of the air inlet 301 by the baffle 204, so that the oil fume is better guided into the negative pressure cavity 201 through the air inlet 301, thereby improving the oil fume absorption efficiency.

[0044] Optionally, the baffle 204 comprises a flow guiding part 205 and a sliding part 206. The sliding part 206 is horizontally slidably connected to one side of the movable opening 203. In this way, the baffle can be horizontally slid, and when the side suction part 300 slides upward, the baffle 204 slides leftward to close the movable opening 203 due to the inclination angle of the side surface on which the air inlet 301 is located, so that the airflow can be guided into the negative pressure cavity 201 through the air inlet 301, thereby improving the oil fume absorption efficiency of the side suction part 300.

[0045] Optionally, the sliding connection comprises a structure connected by a sliding groove and a sliding rail. In this way, the structure is simple, has low cost, and can better realize the sliding connection.

[0046] Optionally, the side of the baffle 204 away from the side suction part 300 is provided with a push spring 207. In this way, the baffle 204 is pushed to the side of the side suction part 300 by the push spring 207, so that the baffle 204 is always in close contact with the side suction part 300, thereby improving the sealing property of the movable opening 203 and further improving the oil fume absorption efficiency.

[0047] Optionally, the negative pressure cavity 201 and the side suction part 300 are connected by a sliding rail assembly. In this way, the sliding between the side suction part 300 and the negative pressure cavity 201 is more stable by the sliding rail assembly, so that the stability of the telescoping movement of the side suction part 300 can be improved.

[0048] Optionally, the sliding assembly comprises a sliding rail 501 and a sliding groove 502. The sliding rail 501 is arranged on the inner side wall of the negative pressure cavity 201, and the sliding groove 502 is arranged on the side suction part 300. In this way, the sliding between the side suction part 300 and the negative pressure cavity 201 is more stable by virtue of the structure of the sliding rail 501 and the sliding groove 502.

[0049] Optionally, the driving device 400 comprises a strip tooth 401 arranged on the side suction part 300, and a power part comprising a motor 402 and a gear connected with the motor 402, the gear being engaged with the strip tooth 401. In this way, the side suction part 300 is driven to extend and retract by virtue of the engagement between the gear and the strip tooth 401, thereby improving the stability of the extension and retraction of the side suction part 300.

[0050] In combination with Figure 7 As shown in the drawings, the embodiment of the present disclosure provides a method for controlling an extractor hood, comprising:

[0051] S01, in the case that the cooking top is in an open state, controlling the side suction part to extend out of the fan part;

[0052] S02, controlling the distance between the side suction part and the cooking top according to the rotating speed of the fan part.

[0053] By virtue of the method for controlling an extractor hood provided by the embodiment of the present disclosure, the distance between the side suction part and the cooking top is controlled according to the rotating speed of the fan part. The faster the rotating speed of the fan part, the stronger the suction capacity required for the extractor hood, and at this time, the distance between the side suction part and the cooking top is made closer, so that the air inlet is closer to the source of the oil fume, and the oil fume can be better sucked, the adjustability of the extractor hood is improved, and the smoke exhaust efficiency of the extractor hood is optimized.

[0054] Optionally, the controlling the distance between the side suction part and the cooking top according to the rotating speed of the fan part comprises: determining the distance corresponding to the rotating speed of the fan part according to a preset corresponding relationship; and adjusting the distance between the side suction part and the cooking top based on the determined distance. In this way, the distance between the side suction part and the cooking top is adjusted by virtue of the corresponding relationship, the adjustment mode is simplified, and the control is more reliable.

[0055] Optionally, the controlling the distance between the side suction part and the cooking top according to the rotating speed of the fan part comprises: obtaining a speed regulation instruction of the fan part, judging the rotating speed of the fan part according to the speed regulation instruction of the fan part, and controlling the distance between the side suction part and the cooking top according to the rotating speed of the fan part. In this way, when the user adjusts the rotating speed of the fan part, the speed regulation instruction of the fan part is obtained, the distance between the side suction part and the cooking top is adjusted at the same time as the rotating speed of the fan part is adjusted, the distance between the side suction part and the cooking top is coordinated with the adjustment of the rotating speed of the fan part, and the efficiency of sucking the oil fume is improved.

[0056] Optionally, the distance between the side suction part and the cooking table is controlled according to the rotating speed of the fan part, which includes detecting the air pressure at the air inlet or air outlet of the fan part, judging the rotating speed of the fan part according to the air pressure, and then controlling the distance between the side suction part and the cooking table according to the rotating speed of the fan part. In this way, the air pressure at the air inlet or air outlet of the fan part is different when the rotating speed of the fan part is different, and the rotating speed of the fan part can be more intuitively and accurately adjusted in the working state of the range hood through the air pressure. For example, when the air pressure of the air outlet of the fan part is high, it indicates that the rotating speed of the fan is high, and the distance between the side suction part and the cooking table is controlled to be closer at this time.

[0057] Optionally, the greater the rotating speed of the fan part is, the smaller the distance between the side suction part and the cooking table is. In this way, when the rotating speed of the fan part is high, the side suction part is closer to the cooking table, and the oil fume suction port exposed outside is larger. The oil fume suction port on the side suction part can quickly suck oil fume into the range hood, improve the oil fume suction capacity, and improve the oil fume suction efficiency.

[0058] Optionally, the rotating speed of the fan part and the distance between the side suction part and the cooking table are both divided into multiple levels, and each level corresponds to a distance between the side suction part and the cooking table. In this way, the rotating speed of the fan part is divided into levels, which is convenient for simplifying the control. For example, the rotating speed of the fan part is divided into high speed, medium speed and low speed, and the distance between the side suction part and the cooking table is divided into close distance, medium distance and far distance. When the rotating speed of the fan part is high speed, the corresponding distance between the side suction part and the cooking table is close distance; when the rotating speed of the fan part is medium speed, the corresponding distance between the side suction part and the cooking table is medium distance; and when the rotating speed of the fan part is low speed, the corresponding distance between the side suction part and the cooking table is far distance.

[0059] Optionally, the rotating speed of the fan part is determined according to the oil fume concentration. In this way, the rotating speed of the fan part is determined according to the oil fume concentration, the rotating speed of the fan part can be directly controlled according to the size of the oil fume concentration, and the oil fume suction capacity of the entire range hood is controlled, and the control is more stable.

[0060] Optionally, the higher the oil fume concentration is, the greater the rotating speed of the fan part is. In this way, when the oil fume concentration is high, the rotating speed of the fan part is increased to improve the oil fume suction capacity of the fan, and after the rotating speed of the fan part is increased, the distance between the side suction part and the cooking table is closer, and the oil fume suction port on the side suction part is closer to the oil fume source, the oil fume suction port is exposed more, and the suction efficiency can be increased by cooperating with a larger suction force.

[0061] Optionally, the oil fume concentration is divided into multiple levels, each level corresponds to a rotating speed of the fan unit, and each rotating speed of the fan unit corresponds to a distance between the side suction unit and the cooking table. In this way, when dealing with different levels of oil fume concentration, different rotating speeds of the fan unit are adopted, and the distance between the side suction unit and the cooking table is different, thereby improving the oil fume suction efficiency for oil fume of different concentrations. For example, the oil fume concentration is divided into three levels: high concentration, medium concentration, and low concentration; the rotating speed of the fan unit is divided into three levels: high speed, medium speed, and low speed; and the distance between the side suction unit and the cooking table is divided into three levels: close distance, medium distance, and far distance. When the oil fume concentration is high, the corresponding rotating speed of the fan unit is high speed and the distance between the side suction unit and the cooking table is close distance; when the oil fume concentration is medium, the corresponding rotating speed of the fan unit is medium speed and the distance between the side suction unit and the cooking table is medium distance; and when the oil fume concentration is low, the corresponding rotating speed of the fan unit is low speed and the distance between the side suction unit and the cooking table is far distance.

[0062] Optionally, the method for controlling the range hood further comprises: detecting the temperature of the cooking table; and determining the working state of the cooking table according to the temperature. In this way, the working state of the cooking table is determined according to the temperature of the cooking table, which is simple, convenient, and relatively accurate.

[0063] Optionally, the temperature of the cooking table is detected as the temperature of a region within 5 cm from the heating area of the cooking table. In this way, the temperature within 5 cm from the heating area of the cooking table is sensed, and the working state of the cooking table is determined more stably according to the temperature.

[0064] Optionally, the heating area of the cooking table is the position of the cooking head.

[0065] Optionally, determining the working state of the cooking table according to the temperature comprises: determining that the cooking table is in an open state when the temperature exceeds a preset temperature. In this way, when the temperature of the cooking table exceeds the preset temperature, it indicates that the cooking table starts to work, and it is more accurate to determine that the cooking table is in the open state at this time.

[0066] Optionally, the preset temperature is greater than or equal to 50 degrees. In this way, the room temperature generally does not exceed 50 degrees. Setting the preset temperature value to be greater than 50 degrees can avoid misjudgment caused by the influence of the room temperature.

[0067] Optionally, the method for controlling the range hood further comprises: detecting the flow condition of the gas, and determining the working state of the cooking table according to the flow condition of the gas. For example, when the gas flowing to the cooking table is detected, it is determined that the cooking table is in the working state. In this way, it is more accurate to determine that the cooking table is in the working state according to the flow condition of the gas, and the side suction unit can be extended to work as soon as the cooking table enters the working state, thereby improving the response speed of the control of the extension of the side suction unit.

[0068] Optionally, the method for controlling the range hood further comprises: in the case that the cooking zone is in the off state, controlling the side suction part to retract into the fan part according to the oil fume concentration. In this way, after the cooking zone stops being used, the side suction part is retracted into the fan part when the oil fume concentration drops to a certain value, thereby reducing the residual oil fume in the kitchen.

[0069] Optionally, controlling the side suction part to retract into the fan part according to the oil fume concentration comprises: controlling the side suction part to retract into the fan part when the oil fume concentration is lower than a preset value. In this way, the oil fume concentration is kept at a lower level when the side suction part is retracted into the fan part after the oil fume concentration drops to the preset value, thereby reducing the residual oil fume in the kitchen.

[0070] In combination Figure 8 As shown in the accompanying drawings, the embodiment of the present disclosure provides a device for controlling a range hood, which comprises a first control module 600 and a second control module 700. The first control module 600 is configured to control the side suction part to extend out of the fan part in the case that the cooking zone is in the on state; and the second control module 700 is configured to control the distance between the side suction part and the cooking zone according to the rotating speed of the fan part.

[0071] By using the device for controlling a range hood provided by the embodiment of the present disclosure, the distance between the side suction part and the cooking zone is controlled according to the rotating speed of the fan part. The faster the rotating speed of the fan part, the stronger the suction capacity required for the oil fume, at which time the distance between the side suction part and the cooking zone is made shorter, so that the air inlet is closer to the source of the oil fume, and the oil fume can be better sucked, thereby improving the adjustability of the range hood and optimizing the exhaust efficiency of the range hood.

[0072] Optionally, the device for controlling a range hood further comprises a detection module 800. The detection module 800 is configured to detect the working state of the cooking zone and the rotating speed of the fan part.

[0073] Optionally, the detection module 800 comprises a temperature detection unit 801. The temperature detection unit 801 is configured to detect the temperature of the cooking zone and determine the working state of the cooking zone according to the temperature. In this way, whether the cooking zone is in the working state is determined by the temperature of the cooking zone, which is simple, convenient and relatively accurate.
