[0111] The embodiment of the present disclosure provides a range hood 100, and the range hood 100 includes an oil net assembly 30 for the range hood 100 according to any one of the above embodiments.

[0112] The range hood 100 provided in the embodiment of the present disclosure includes the oil net assembly 30 for the range hood 100 of any one of the above-mentioned embodiments, and thus has the beneficial effects of any one of the above-mentioned oil net assemblies 30 for the range hood 100, which will not be elaborated herein.

[0113] Alternatively, if Figure 3 As shown, the oil net assembly 30 is located at the connection point between the smoke collecting chamber 1011 and the smoke exhaust passage 1023, and the oil smoke in the smoke collecting chamber 1011 flows into the smoke exhaust passage 1023 through the oil net assembly 30. In this way, the oil net assembly 30 can adjust the opening area from the smoke collecting chamber 1011 to the smoke exhaust passage 1023, thereby adjusting the air volume in the oil smoke passage, so that the air volume in the oil smoke passage can be adjusted without adjusting the fan 1021, thereby adjusting the air suction volume of the range hood 100, and saving the energy consumption of the range hood 100.

[0114] Optionally, the range hood 100 includes a controller, which is electrically connected to the driving device 305 , and the controller is configured to control the operation of the driving device 305 , thereby controlling the movement of the first cover plate 302 and the second cover plate 303 .

[0115] In the disclosed embodiment, the controller is electrically connected to the driving device 305 , so that the first cover plate 302 and the second cover plate 303 can move automatically, thereby improving the intelligence level of the range hood 100 .

[0116] Optionally, the range hood 100 further includes a first detection device 40, which is used to detect the thermal radiation value of the stove; the controller is electrically connected to the first detection device 40, and the controller is configured to control the movement of the first cover plate 302 and the second cover plate 303 according to the thermal radiation value of the stove.

[0117] In the disclosed embodiment, the controller can accurately identify the heat radiation value on the surface of the stove, and then control the movement of the first cover plate 302 and the second cover plate 303, thereby changing the opening area of ​​the oil net 301. The change in the opening area of ​​the oil net 301 can change the wind speed in the smoke collection chamber 1011, so that the air volume at the entrance of the smoke collection chamber 1011 can be adjusted without adjusting the rotation speed of the fan 1021, thereby providing a smoke collection effect.

[0118] Optionally, the first detection device 40 is a far infrared sensor.

[0119] Optionally, the first detection device 40 is disposed on the front side of the bottom of the smoke collecting hood 101, so that the heat radiation value of the stove can be better detected.

[0120] The range hood 100 is located above the cooker, and the cooker includes a gas stove 503. There are multiple gas stoves 503, and the multiple gas stoves 503 include a first gas stove 501 and a second gas stove 502. The second gas stove 502 is located on the left side of the first gas stove 501; wherein the first gas stove 501 corresponds to the first smoke collection area 1012, and the second gas stove 502 corresponds to the second smoke collection area 1013.

[0121] When the first gas stove 501 is started, when the first detection device 40 detects that the thermal radiation value of the oil smoke generated by the first gas stove 501 is greater than or equal to the first preset value, the controller controls the first cover plate 302 to move to the first position, and controls the second cover plate 303 to move to the fourth position, so that the first through hole 3011 of the oil net 301 is opened and the second through hole 3012 of the oil net 301 is closed. At the same time, the controller controls the fan 1021 to work, so that the first smoke collecting area 1012 starts to collect smoke.

[0122] When the second gas stove 502 is started, when the first detection device 40 detects that the thermal radiation value of the oil smoke generated by the second gas stove 502 is greater than or equal to the second preset value, the controller controls the second cover plate 303 to move to the second position, and controls the second cover plate 303 to move to the third position, so that the first through hole 3011 of the oil net 301 is closed and the second through hole 3012 of the oil net 301 is opened. At the same time, the controller controls the fan 1021 to work, so that the second smoke collecting area 1013 starts to collect smoke.

[0123] When the first gas stove 501 and the second gas stove 502 are working at the same time, the first detection device 40 detects the heat radiation value of the oil smoke generated by the first gas stove 501 and the second gas stove 502. When the heat radiation value is greater than or equal to the third preset value, the controller controls the first cover plate 302 to move to the first position, and controls the second cover plate 303 to move to the third position, so that the first through hole 3011 and the second through hole 3012 are opened. At the same time, the controller controls the fan 1021 to work, so that the first smoke collecting area 1012 and the second smoke collecting area 1013 start working at the same time.

[0124] The range hood 100 also includes a fan 1021 and a second detection device. The fan 1021 is located in the smoke exhaust channel 1023, and is used to drive the smoke in the smoke collection chamber 1011 to flow through the oil net assembly 30 and then be discharged from the range hood 100; the second detection device is used to detect the concentration of particulate matter in the environment where the range hood 100 is located; wherein the second detection device and the fan 1021 are both electrically connected to the controller, and the controller is configured to control the operation of the fan 1021 according to the concentration of particulate matter in the environment where the range hood 100 is located.

[0125] In the disclosed embodiment, the range hood 100 can control the operation of the fan 1021 according to the concentration of particulate matter in the environment in which the range hood 100 is located, thereby adjusting the suction force of the fan 1021 to reduce the concentration of particulate matter in the environment.

[0126] When the concentration of particulate matter in the environment where the range hood 100 is located is greater than or equal to the first preset concentration, the controller controls the fan 1021 to operate at a first speed, increases the air volume of the fan 1021, and increases the decreasing speed of the concentration of particulate matter in the environment where the range hood 100 is located. When the concentration of particulate matter in the environment where the range hood 100 is located is less than the first preset concentration, the controller controls the fan 1021 to operate at a second speed to save energy consumption of the fan 1021, wherein the first speed is greater than the second speed.

[0127] Here, when the concentration of particulate matter in the environment where the range hood 100 is located is greater than or equal to the first preset concentration, it means that the range hood 100 has smoke leakage and overflow, and the speed of the fan 1021 is increased to increase the falling speed of the particles. When the concentration of particulate matter in the environment where the range hood 100 is located is less than the first preset concentration, it means that the range hood 100 does not have smoke leakage and overflow, and the controller controls the fan 1021 to operate at the second speed to maintain the exhaust volume of the fan 1021, which can ensure that the concentration of particulate matter in the environment is less than the preset concentration and save the energy consumption of the fan 1021.

[0128] Optionally, when the first gas stove 501 is working and the first through hole 3011 is opened, when the heat radiation value of the first gas stove 501 is less than or equal to the fourth preset value, the controller controls the first cover plate 302 to move to the fifth position to reduce the opening area of ​​the first through hole 3011, wherein the fourth preset value is less than the first preset value. In this way, when the heat radiation value of the first gas stove 501 becomes smaller, the first cover plate 302 is controlled to move to reduce the opening area of ​​the first through hole 3011, thereby ensuring the air intake of the range hood 100.

[0129] Optionally, when the second gas stove 502 is working and the second through hole 3012 is opened, when the heat radiation value of the second gas stove 502 is less than or equal to the fifth preset value, the controller controls the second cover plate 303 to move to the sixth position to reduce the opening area of ​​the second through hole 3012, wherein the fifth preset value is less than the second preset value. In this way, when the heat radiation value of the second gas stove 502 becomes smaller, the second cover plate 303 is controlled to move to reduce the opening area of ​​the second through hole 3012, thereby ensuring the air extraction volume of the range hood 100.

[0130] Optionally, when the heat radiation value of the first gas stove 501 is greater than the heat radiation value of the second gas stove 502, the controller controls the first cover plate 302 and the second cover plate 303 to move, and makes the opening area of ​​the first through hole 3011 greater than the opening area of ​​the second through hole 3012. In this way, the air suction volume of the first smoke collecting area 1012 is greater than the air suction volume of the second smoke collecting area 1013, so that the range hood 100 can adjust the air suction volume on both sides according to different working conditions of the gas stove 503, thereby improving the smoke extraction effect and flexibility of the range hood 100.

[0131] Optionally, when the concentration of particulate matter in the environment of the range hood 100 is greater than or equal to a second preset concentration, the controller controls the movement of the first cover plate 302 and the second cover plate 303 to open the first through hole 3011 and the second through hole 3012, and at the same time controls the fan 1021 to rotate at a third speed to increase the exhaust volume and exhaust speed of the range hood 100 and accelerate the descending speed of the particles in the environment, wherein the second preset concentration is greater than the first preset concentration, and the third speed is greater than the first speed.

[0132] For example, Fig.16 As shown, the embodiment of the present disclosure provides a control method for a range hood:

[0133] S101, the controller controls the operation of the range hood according to the heat radiation value of the gas stove;

[0134] S102, when the first gas stove is turned on and the heat radiation value of the first gas stove is greater than or equal to the first preset value, the controller controls the first cover plate to move to the first position, and controls the second cover plate to move to the fourth position, so as to open the first through hole and close the second through hole;

[0135] S103, when the second gas stove is turned on and the heat radiation value of the second gas stove is greater than or equal to the second preset value, the controller controls the first cover plate to move to the second position, and controls the second cover plate to move to the third position, so as to close the first through hole and open the second through hole;

[0136] S104, when the first gas stove and the second gas stove are both turned on, and the heat radiation values ​​of the first gas stove and the second gas stove are both greater than or equal to a third preset value, the range hood controls the first cover plate to move to the first position, and controls the second cover plate to move to the third position, so as to open the first through hole and the second through hole;

[0137] S105, the range hood controls the operation of the fan according to the concentration of particulate matter in the environment where the range hood is located;

[0138] S106, when the concentration of particulate matter in the environment where the range hood is located is greater than or equal to a first preset concentration, the range hood controls the fan to operate at a first speed;

[0139] S107: When the concentration of particulate matter in the range hood environment is less than a first preset concentration, the range hood controls the fan to operate at a second speed, and the first speed is greater than the second speed.

[0140] The disclosed embodiment further provides an integrated stove 50, which includes the range hood 100 of any one of the above-mentioned embodiments.

[0141] The integrated stove 50 provided in the embodiment of the present disclosure includes the range hood 100 of any one of the above embodiments, and therefore has the beneficial effects of the range hood 100 of any one of the above embodiments.

[0142] The integrated stove 50 includes a gas stove 503, which is located below the integrated stove 50. There are multiple gas stoves 503, including a first gas stove 501 and a second gas stove 502. The second gas stove 502 is located on the left side of the first gas stove 501; wherein the first gas stove 501 corresponds to the first smoke collection area 1012, and the second gas stove 502 corresponds to the second smoke collection area 1013. Here, as Fig.14 As shown, the first gas stove 501 corresponds to the first smoke collecting area 1012, which means that the first smoke collecting area 1012 matches the smoke diffusion area generated by the first gas stove 501. The second gas stove 502 corresponds to the second smoke collecting area 1013, which means that the second smoke collecting area 1013 matches the smoke diffusion area generated by the second gas stove 502.

[0143] In the disclosed embodiment, a large negative pressure area lower than the cabinet countertop is generated above the corresponding gas stove, and the oil fume diffusion area is effectively gathered and collected according to the oil fume rising and diffusion mechanism, thereby preventing the occurrence of smoke leakage / overflow during cooking.
