In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

Referring to fig. 1, a range hood 100 according to an embodiment of the present disclosure includes a box assembly 1, a smoke collecting hood assembly 2, a fan, an electric control system, a lighting system, and a power switch.

Wherein, box subassembly 1 includes decorative board 11, box 12 and check valve, and decorative board 11 is installed in the outside of box 12, and the check valve is installed in the top air outlet department of box 12, and above-mentioned fan is installed in box 12.

Referring to fig. 1 and 2, the above-described smoke collecting hood assembly 2 includes a smoke collecting hood 21 and a shutter 22, the smoke collecting hood 21 being installed below the case 12, and a smoke intake chamber being formed in the smoke collecting hood 21. For the top-suction type range hood, the bottom plate of the fume collecting hood 21 is provided with a fume inlet 210 communicated with the fume inlet cavity; for the side-draft range hood, the side surface of the fume collecting hood 21 is provided with a fume inlet 210 communicated with the fume inlet chamber. The shutter 22 is installed at the smoke inlet 210 to close the smoke inlet 210.

For the top-suction range hood, the distance between the smoke inlet 210 of the range hood 100 and the pot on the cooking range is large, so that the problems that the oil smoke on one side cannot be discharged timely and the oil smoke escapes easily occur; if a near-suction range hood is adopted, although the distance between the smoke inlet 210 of the range hood 100 and the cookware on the cooking range is small, the oil smoke discharge efficiency is improved, the steamer adopting the large height is cooked, and when the shielding piece 22 installed at the smoke inlet 210 of the range hood 100 is opened, the shielding piece 22 easily touches the steamer, so that the user experience is poor.

Therefore, in order to solve the above problem, referring to fig. 3, 4 and 7, the smoke inlet in the embodiment of the present application is elongated, and the elongated smoke inlet 210 extends in the same direction as the longitudinal direction P of the smoke collecting hood 21. The number of the shielding pieces 22 is multiple, the shielding pieces 22 are all arranged at the smoke inlet 210 and are sequentially distributed along the length direction of the smoke inlet 210, and the shielding pieces 22 are used for corresponding to a plurality of cooking ranges on the gas stove one by one; the range hood 100 further comprises a driving device 3, a plurality of pot position detecting devices 5 shown in fig. 6, a receiver and a controller, wherein the driving device 3 can drive one or more shielding pieces 22 to close or open in an outward rotating manner; the plurality of pot position detection devices 5 are all arranged outside the smoke collecting hood and are used for corresponding to a plurality of cooking range heads on the gas stove one by one; the receiver is used for receiving opening information of a plurality of cooking ranges sent by the gas stove, wherein the opening information comprises position information of the cooking ranges in an opening state; the controller is electrically connected with the driving device, the pot position detection device 5 and the receiver. The controller is used for controlling the driving device to open or keep closed the corresponding shielding piece 22 according to the opening information received by the receiving module and the height value of the cookware detected by the cookware height detecting device 5. The longitudinal direction P of the smoke collecting hood 21 is parallel to the direction in which the burner of the gas range is arranged.

Because a plurality of shielding pieces 22 are installed at the smoke inlet 210 of the smoke collecting cover 21 in the range hood 100 of the embodiment of the present application, the plurality of shielding pieces 22 are sequentially distributed along the length direction of the smoke inlet 210 and are in transmission connection with the driving device 3, a plurality of cookware height detection devices 5 and receivers are further installed on the smoke collecting cover 21, the plurality of cookware height detection devices 5, the plurality of shielding pieces 22 are all used for corresponding to a plurality of burners on the gas stove one to one, the receivers can receive opening information of the plurality of burners sent by the gas stove, namely, position information of the burners in an opening state is received. According to the opening information received by the receiver and the height value of the cooker detected by the cooker height detection device, the controller controls the driving device to open or keep closed the corresponding shielding piece. For example, when the height value of a pot placed on any cooking range in an open state is higher than a set height threshold (for example, the pot is a steamer with a large height), the controller controls the driving device 3 to keep the shielding piece 22 at the smoke inlet corresponding to the cooking range closed, so that the shielding piece 22 does not interfere with the pot, and the user experience is good; when the height value of the pot placed on any cooking range in the opening state is lower than a set height threshold (if the pot is a low-height frying pan), the controller controls the driving device 3 to open the shielding piece 22 corresponding to the cooking range, and because the cooking range is short in distance from the smoke inlet 210, the oil smoke generated at the cooking range can be rapidly pumped away, so that the problem of oil smoke escape caused when the oil smoke on one side is not discharged in time is reduced. The control process of the shielding piece 22 on the range hood 100 of the embodiment of the application can be automatically completed, and the automation degree of the range hood is improved.

It should be noted that the structural form of the above-mentioned shielding member 22 can be selected according to actual needs, for example, the shielding member 22 is a baffle plate, the shape of the baffle plate is the same as the shape of the smoke inlet 210, and the length of the baffle plate is smaller than the length of the smoke inlet 210. Of course, the shutter 22 may have other configurations such as a stopper. The receiver comprises a receiving module, the receiving module is any one of a WIFI module, a Bluetooth module, a 433m wireless module and a 2.4G module, and the receiver is low in cost and high in efficiency.
