Therefore, based on the bracket 42 of the movable assembly, the telescopic cover 30 can be stably connected to the air inlet 11 without additional structural members for fixing the telescopic cover, and the structure is simple. It should be understood that the bracket 42 is fixed to the bottom of the chassis 10, and the telescopic cover 30 may be fixed to the bracket 42 by a fixing block, for example.

As an exemplary embodiment, the support 42 includes a first support 421 and a second support 422, the first support 421 is located at a left end of the inlet 11, for example, the second support 422 is located at a right end of the inlet 11, a screw 43 driven by a driving member 44 is disposed between the first support 421 and the second support 422, the driving member 44 is a motor, for example, the driving member 44 is mounted on the first support 421, and the movable support 41 is disposed on the screw 43. Thus, when the driving member 44 drives the screw 43 to rotate, the moving frame 41 can move along the axial direction of the screw 43, and the structure is simple.

Further, a guide rail 45 parallel to the screw 43 is further disposed between the first support 421 and the second support 422, and the moving frame 41 has a guide frame body 411 connected to the guide rail 45.

Thus, the distance from the smoke collecting hood assembly 50 to the cooker can be conveniently detected, and the principle that the first sensor 71 and the second sensor 72 detect the distance belongs to the prior art, so that the repeated description is omitted here.

It will be appreciated that range hoods will typically have a controller (the controller is not shown in the figures) to which the first sensor 71, the second sensor 72 and the telescopic drive member are electrically connected respectively. In this way, the controller can adjust the position of the smoke collecting hood assembly 50 based on the values fed back by the first sensor 71 and the second sensor 72, so as to prevent the air guide duct 20 from touching the pot during movement. Of course, the driver 44 is also electrically connected to the controller. Specifically, when the range hood is in the closed state, the air duct 20 is located on the center line of the chassis 10, and the middle position of the bottom of the chassis 10 is located on the center line (as shown in fig. 3). As shown in fig. 6, the distance between the bottom of the smoke collecting hood assembly 50 and the first sensor 71 is H1, since the second sensor 72 and the first sensor 71 are located on the same horizontal plane, and H1 is also the distance between the bottom of the smoke collecting hood assembly 50 and the second sensor 72, when a cooker on one side is used, the sensor on the side detects the distance H2 of the pot 200, as shown in fig. 7, when a cooker on the left side is used, the first sensor 71 detects the distance H2 of the pot 200 and transmits the signal to the controller, the controller compares the data with the preset most suitable distance H3, and if H2-H1 > H3, the controller drives the telescopic driving member to extend the telescopic rod 61 downwards; if H2-H1 is less than H3, the controller drives the telescopic driving piece to enable the telescopic rod 61 to contract upwards, so that the distance between the bottom of the smoke collecting hood assembly 50 and the highest point of the pot is H3, and H3 is set to be 25 cm-50 cm, for example, good smoking effect can be achieved, and the sight of a user is not affected. When the telescopic driving member stops moving, the controller can also control the driving member 44 to drive the air guiding pipe 20 to move to the side S1, and then the fan is started. That is, in the adjustment, the height of the hood assembly 50 is generally adjusted first, and then the left and right positions of the air guide duct 20 are adjusted to prevent the air guide duct 20 from touching the pot during movement.

Because the conventional kitchen range is provided with the left and right kitchen ranges, the left and right kitchen ranges respectively correspond to the first cooking range 91 and the second cooking range 92 which are described later, the distance between the left and right kitchen ranges is generally 42cm, and when the S1 is set to be 21cm +/-10 cm, the smoke collecting hood assembly 50 can be enabled to be opposite to the cooker 200.

Thus, the smoke collecting hood assembly 50 can collect oil stains and has an illumination function. Further, the illumination lamp 52 is a ring-shaped body, which is not only easy to install but also has a larger irradiation area.

As an exemplary embodiment, the smoke collecting cover body 51 is in a circular truncated cone shape, and the outer diameter of the distal end 511 is smaller than that of the annular proximal end 512; the oil screen 53 is circular truncated cone-shaped, and the outer diameter of the first end 531 is smaller than the outer diameter of the second end 532. Therefore, the smoke collecting hood body 51 is more convenient to collect smoke, and the oil screen 53 can also conveniently guide oil stains into the oil cup 54 at the bottom of the oil screen 53.

Referring to fig. 6, 7 and 8 again, the smoke collecting hood body 51 has the maximum outer diameter D1, the first cooking range 91, the second cooking range 92 and the pan center 93 are arranged below the case, a distance L1 is provided between the pan center 93 and the wall 300 for fixing the case 10, a distance D3 is provided between the first cooking range 91 and the second cooking range 92, the pan 200 with the diameter D2 can be arranged on the first cooking range 91 or the second cooking range 92, wherein D3-D2 is not less than D1 is not less than 2 × L1. Therefore, the smoke collecting cover body 51 can be over against the center of the cooker, and a good smoking effect can be achieved when the cooker corresponding to the first cooking range 91 and the cooker corresponding to the second cooking range 92 are opened simultaneously.

It should be understood that, when the left and right cookers are used simultaneously, as shown in fig. 7, the first sensor 71 and the second sensor 72 respectively detect the distance from the bottom of the smoke collecting hood assembly 50 to the cooker, the controller compares the data fed back by the first sensor 71 with the data fed back by the second sensor 72, compares the smaller value with the preset optimal distance H3, and controls the telescopic driving member to move to control the telescopic rod 61 to extend and retract, after the telescopic driving member stops moving, the fan is directly started, and the air guiding pipe 20 is not moved at the center of the smoke machine (i.e., the center of the cabinet).
