Modifying the specific implementation manners of the present invention or equivalently replacing some technical features without departing from the spirit of the present invention shall be covered within the scope of the technical solutions claimed by the present invention.

[0036] Please refer to Figure 1 and Figure 2 , the present invention provides a range hood, which includes a chassis 1, a left smoke gathering structure 2, a right smoke gathering structure 3, a left driving structure (not shown in the figure) and a right driving structure (not shown in the figure). A left smoke inlet 100 and a right smoke inlet 200 are provided at the lower end of the chassis 1. The left smoke gathering structure 2 and the right smoke gathering structure 3 are both installed in the chassis 1. The left driving structure and the right driving structure are both installed in the chassis 1. The left driving structure is in transmission connection with the left smoke gathering structure 2, and the left driving structure can drive the left smoke gathering structure 2 to extend out of and retract into the chassis 1 through the left smoke inlet 100. The right driving structure is in transmission connection with the right smoke gathering structure 3, and the right driving structure can drive the right smoke gathering structure 3 to extend out of and retract into the chassis 1 through the right smoke inlet 200.

[0037] The range hood provided by the utility model is provided with a left drive structure drivingly connected to the left smoke collecting structure 2 and a right drive structure drivingly connected to the right smoke collecting structure 3 separately, so that the left smoke collecting structure 2 and the right smoke collecting structure 3 can extend out of the chassis 1 separately or simultaneously to adapt to different cooking conditions, while saving resources and achieving an aesthetic effect. Specifically, when only the left burner is cooking, the left drive structure drives the left smoke collecting structure 2 to extend out of the chassis 1 and descend to a preset position, so that the left smoke collecting structure 2 is close to the left burner, thereby better absorbing the oil fume at the left burner. At the same time, the right smoke collecting structure remains retracted in the chassis 1, which can avoid the right smoke collecting structure blocking the cooking view and is beneficial for the user to cook; when only the right burner is cooking, the right drive structure drives the right smoke collecting structure to extend out of the chassis 1 and descend to a preset position, so that the right smoke collecting structure 3 is close to the right burner, thereby better absorbing the oil fume at the right burner. At the same time, the left smoke collecting structure remains retracted in the chassis 1, which can avoid the left smoke collecting structure blocking the cooking view and is beneficial for the user to cook; when the left burner and the right burner are cooking simultaneously, the left drive structure and the right drive structure operate simultaneously to drive the left smoke collecting structure 2 and the right smoke collecting structure 3 to extend out of the chassis 1 simultaneously and descend to a preset position, thereby absorbing the oil fume at the left burner and the right burner simultaneously; after the cooking operation is completed, the left drive structure and the right drive structure drive the left smoke collecting structure 2 and the right smoke collecting structure 3 to retract into the chassis 1, thereby realizing the hiding of the left smoke collecting structure 2 and the right smoke collecting structure 3 in the chassis 1 and achieving a better aesthetic effect.

[0038] Optionally, both the left smoke collecting structure 2 and the right smoke collecting structure 3 include a smoke collecting hood 101 and an oil net 102. A smoke collecting cavity is arranged in the smoke collecting hood 101. The oil net 102 is arranged in the smoke collecting cavity and is used for filtering oil fume.

[0039] Optionally, the left smoke collecting structure 2 and the right smoke collecting structure 3 further include an oil cup 103. The oil cup 103 is detachably installed in the smoke collecting cavity and is located on the lower side at the rear end of the oil net 102. The oil cup 103 is used for receiving the oil stains in the oil net 102 and the smoke collecting hood 101, and the user can clean the oil cup 103 regularly by detaching the oil cup 103.

[0040] Optionally, the left smoke collecting structure 2 and / or the right smoke collecting structure 3 can extend out of the chassis 1 by a first distance L1 and a second distance L2 to achieve different smoke collecting effects.

[0041] Optionally, the first distance L1 is 120 mm and the second distance L2 is 200 mm, which can meet the general cooking needs.

[0042] Optionally, it further includes a fan. The fan is installed in the chassis 1. The air inlet of the fan is communicated with the left smoke collecting structure 2 and the right smoke collecting structure 3, and the air outlet of the fan is communicated with the public flue of the building.

[0043] Optionally, the blower includes a low - speed gear and a high - speed gear.

[0044] Specifically, the range hood provided in this embodiment includes the following four - gear oil - fume extraction modes:

[0045] I. Low - speed gear mode

[0046] The blower operates at a low - speed gear, and the left smoke - gathering structure 2 and / or the right smoke - gathering structure 3 extend from the chassis 1 by a first distance L1, forming a smoke - gathering shape for downward - probing smoke extraction, with relatively low noise.

[0047] II. Medium - speed gear mode

[0048] The blower operates at a high - speed gear, and the left smoke - gathering structure 2 and / or the right smoke - gathering structure 3 extend from the chassis 1 by a first distance L1, forming a smoke - gathering shape for downward - probing smoke extraction. The blower speed is higher than that in the low - speed gear mode, so the oil - fume extraction effect is better than that in the low - speed gear mode.

[0049] III. High - speed gear mode

[0050] The blower first operates at a low - speed gear, and the left smoke - gathering structure 2 and / or the right smoke - gathering structure 3 extend from the chassis 1 by a second distance L2 to focus on the oil - fume generation area. At this time, the blower speed is adjusted according to the oil - fume concentration. That is, when the oil - fume concentration is low, the blower still operates at a low - speed gear, and when the oil - fume concentration is high, the blower speed is adjusted to a high - speed gear, thus achieving the effect of improved oil - fume extraction ability and possible reduction in noise.

[0051] IV. Stir - frying gear mode

[0052] The blower operates at a high - speed gear, and the left smoke - gathering structure 2 and / or the right smoke - gathering structure 3 extend from the chassis 1 by a second distance L2 to focus on the oil - fume generation area, achieving an efficient smoke - exhaust effect of low - suction type.

[0053] Optionally, it further includes an optical oil - fume concentration monitor (not shown in the figure). The optical oil - fume concentration monitor is installed at the lower end of the chassis 1 and is communicatively connected to the blower, and is used to detect the oil - fume concentration at the left burner and the right burner.

[0054] Optionally, it further includes a flue and a flexible smoke pipe. The flue is arranged inside the chassis 1, the blower is arranged inside the flue, the air outlet of the flue is communicated with the common flue, and the air inlet of the flue is communicated with the left smoke - gathering structure 2 and the right smoke - gathering structure 3 through the flexible smoke pipe. By setting the flexible smoke pipe, the left smoke - gathering structure 2 and the right smoke - gathering structure 3 can be connected to the flue both when extending and retracting from the chassis 1, ensuring the smoke - exhaust effect.

[0055] Optionally, it further includes a wind deflector (not shown in the figure), which is arranged in the flue and used to open and close the flue. When the left smoke collecting structure 2 and / or the right smoke collecting structure 3 extends out of the machine case 1, the wind deflector opens the flue to facilitate smoke exhaust; while when the left smoke collecting structure 2 and the right smoke collecting structure 3 retract into the machine case 1, the wind deflector closes the flue to prevent the oil fume in the common flue from flowing back.

[0056] Optionally, it further includes a control panel driving structure and a control panel 5 installed in the machine case 1. A control panel opening is also provided at the lower end of the machine case 1, and the control panel opening is arranged on the front side of the left smoke inlet 100 and / or the right smoke inlet 200. The control panel driving structure is in transmission connection with the control panel 5, and the control panel driving structure can drive the control panel 5 to extend out of and retract into the machine case 1 through the control panel opening.

[0057] Specifically, when the range hood is turned on, the control panel driving structure drives the control panel 5 to extend out of the machine case 1 to facilitate the user to operate the range hood through the control panel 5. When the range hood is turned off, the control panel driving structure drives the control panel 5 to retract into the machine case 1 so that the control panel 5 is hidden in the machine case 1, achieving a better aesthetic effect.

[0058] Optionally, it further includes a gesture switch sensor 4. The gesture switch sensor 4 is communicatively connected with the control panel driving structure, and the control panel driving structure drives the control panel 5 to extend and retract according to the sensing signal of the gesture switch sensor 4. The user can instruct the control panel driving structure to drive the control panel 5 to extend out of the machine case 1 through the gesture switch sensor 4 to facilitate the user to operate the range hood.

[0059] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the inventive concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
