All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

As described in the background art, the range hood with the turning plate in the related art comprises a shell, a turning plate and an oil cup, wherein the oil cup is arranged at the rear end of the bottom of the shell, the bottom of the shell is provided with a smoke collecting cavity, and the turning plate is hinged to the bottom of the shell. The turning plate is opened to expose the smoke collecting cavity so as to be convenient for sucking the oil smoke, and the effect of collecting the oil smoke can be improved after the turning plate is opened. The cigarette collecting cavity is shielded after the turning plate is folded, and the turning plate is obliquely arranged relative to the horizontal plane after being folded, so that oil drops on the inner side of the turning plate flow into the oil cup under the action of self gravity.

However, after the flap is retracted, oil drops on the inner side of the flap are easy to drop from a gap between the flap and the oil cup, so that the cooking surface is polluted. The inventor researches have found that the reason for this problem is that, in order to avoid interference between the turning plate and the oil cup during rotation, a certain gap is formed between the turning plate and the oil cup after the turning plate is retracted, so that the turning plate can rotate freely.

The principles and features of embodiments of the present application are described below with reference to the drawings, the examples being provided for the purpose of illustrating the embodiments of the present application and not for the purpose of limiting the scope of the embodiments of the present application.

Fig. 1 is a schematic structural diagram of a range hood according to an embodiment of the present application, fig. 2 is a schematic structural diagram of the range hood according to an embodiment of the present application when a flap is in a retracted state, and fig. 3 is a schematic structural diagram of the range hood according to an embodiment of the present application when the flap is in an open state.

Referring to fig. 1-3, the range hood provided in the embodiment of the application includes a housing 10, a fan, an oil cup 20, a turning plate 30 and an oil guide plate 40, wherein a smoke inlet is formed at the bottom of the housing 10, the fan is arranged in the housing 10, and when the fan works, negative pressure is formed at the smoke inlet, so that gases such as oil smoke generated in the cooking process enter the housing 10 from the smoke inlet and are discharged outdoors, so that the air quality of a kitchen is improved.

Referring to fig. 1 and 2, when the flap 30 is in a retracted state, the flap 30 may be disposed obliquely with respect to the vertical direction, and the flap 30 may be attached to the bottom of the housing 10, the top end of the flap 30 is closer to the user side of the housing 10 than the bottom end, and the top end of the flap 30 is disposed rotatably with respect to the housing 10, so as to shield the smoke inlet, so that, on one hand, the smoke can be prevented from flowing backward into the kitchen, and on the other hand, the decorative effect of the range hood can be improved after shielding the smoke inlet.

During the gradual opening of the flap 30 from the stowed position, the flap 30 rotates in a direction away from the housing 10, and the bottom end of the flap 30 rotates toward the user side of the housing 10.

When the flap 30 is in the open state, referring to fig. 3, the bottom end of the flap 30 is rotated to the outside of the user side of the housing 10, so as to improve the smoke collecting effect of the range hood.

The oil cup 20 is disposed at the bottom of the housing 10, the oil cup 20 may extend along the length direction of the housing 10, and the opening of the oil cup 20 is upward. When the flap 30 is in the stowed state, the cup 20 is proximate the bottom end of the flap 30.

When the flap 30 is in the open state, oil droplets or the like in gas such as oil smoke or the like generated during cooking adhere to the oil guide plate 40 and the inner side of a part of the flap 30, and since the oil guide plate 40 is shielded below a part of the flap 30, the oil droplets adhere to the inner wall of the oil guide plate 40 and do not adhere to the flap 30 facing the oil guide plate 40. The inner side of the partial flap 30 where the oil guide plate 40 is not provided is directly released from the gas such as the oil smoke, and therefore, oil droplets are also adhered.

After cooking, the turning plate 30 is gradually retracted from the open state, and when the turning plate 30 is in the retracted state, as the turning plate 30 and the oil guide plate 40 are both extended obliquely downwards, oil drops on the inner side of the turning plate 30 flow downwards to the oil guide plate 40, and the oil drops on the oil guide plate 40 flow downwards into the oil cup 20 along the oil guide plate 40 so as to avoid the oil drops from polluting the table top.

The range hood in the embodiment comprises a shell 10, an oil cup 20, a turning plate 30 and an oil guide plate 40, wherein the turning plate 30 and the oil cup 20 are arranged at the bottom of the shell 10, one end of the turning plate 30 is rotatably arranged relative to the shell 10, and the other end of the turning plate 30 is arranged close to the oil cup 20; the oil guide plate 40 is obliquely arranged relative to the horizontal plane, and an included angle is formed between the oil guide plate 40 and the turning plate 30, one end of the oil guide plate 40 in the width direction is connected to one side of the turning plate 30 facing the shell 10, and the other end of the oil guide plate 40 in the width direction is located above the opening of the oil cup 20. Through the arrangement, when the turning plate 30 is in the retracted state, one end of the oil guide plate 40, which is far away from the turning plate 30, extends to the upper side of the opening of the oil cup 20, so that oil drops on the inner side of the turning plate 30 flow into the oil cup 20 along the oil guide plate 40, and the oil drops are prevented from polluting a table top.

In some embodiments, the range hood may further include a drive mechanism configured to drive rotation of flap 30 relative to housing 10.

In some specific implementations, an end of the flap 30 facing away from the oil cup 20 may be provided with a rotation shaft, which is rotatably inserted on the housing 10. The driving mechanism may include a driving motor, a motor shaft of the driving motor is in transmission connection with the rotating shaft, and the rotating shaft rotates along with the rotation of the motor shaft.

The turning plate 30 is driven to rotate by the driving motor, so that the device is more convenient and quick, and saves time and labor.

When the turning plate 30 is in the retracted state, the included angle between the oil guide plate 40 and the horizontal plane can be 6 degrees, so that the oil guide plate 40 can freely rotate along with the turning plate 30, and oil drops on the inner side of the oil guide plate 40 can flow into the oil cup 20 along the included angle.

In other embodiments, when flap 30 is in the stowed state, flap 30 may extend in a horizontal direction; when the turning plate 30 is in an open state, the turning plate 30 is obliquely arranged relative to the vertical direction, the top end of the turning plate 30 is rotatably arranged relative to the shell 10, and the bottom end of the turning plate 30 is far away from the oil cup 20 than the top end, so that the smoke collecting effect of the range hood is improved. The oil guide plate 40 is arranged on the inner side of the turning plate 30, when the turning plate 30 is in a retracted state, the oil guide plate 40 is obliquely arranged relative to the horizontal plane, the top end of the oil guide plate 40 is connected to the inner side of the turning plate 30, and the bottom end of the oil guide plate 40 extends to the upper side of the opening of the oil cup 20, so that oil drops on the inner side of the turning plate 30 flow into the oil cup 20 along the oil guide plate 40, and the oil drops are prevented from polluting a table top.

In some embodiments, the oil guide plate 40 has a first end near the oil cup 20, the oil cup 20 has a second end near the oil guide plate 40, and a radius of rotation of the first end of the oil guide plate 40 relative to the rotation axis of the flap 30 is less than or equal to a distance between the second end of the oil cup 20 and the rotation axis, so that the oil guide plate 40 does not collide with the oil cup 20 during rotation of the flap 30 around the rotation axis, and the like, so that the oil guide plate 40 can normally rotate with the flap 30.

In the implementation that the rotation radius of the end of the oil guide plate 40 near the oil cup 20 with respect to the rotation axis of the flap 30 is smaller than the distance between the end of the oil cup 20 near the oil guide plate 40 and the rotation axis, when the oil guide plate 40 rotates to be near the oil cup 20, a gap is formed between the end of the oil guide plate 40 and the oil cup 20, so that the oil guide plate 40 does not make any contact with the oil cup 20, and the oil guide plate 40 can freely rotate along with the flap 30.

In the implementation manner that the rotation radius of the end, close to the oil cup 20, of the oil guide plate 40 relative to the rotation axis of the turning plate 30 is equal to the distance between the end, close to the oil guide plate 40, of the oil cup 20 and the rotation axis, when the oil guide plate 40 rotates to be close to the oil cup 20, the tail end of the oil guide plate 40 just contacts with the edge of the oil cup 20, and when the oil guide plate 40 rotates, only slight friction occurs with the oil cup 20, collision cannot occur with the oil cup 20, and the oil guide plate 40 can still rotate freely along with the turning plate 30.

In some embodiments, when the flap 30 is in the retracted state, one end of the flap 30, which is close to the oil cup 20, abuts against the edge of the opening, so that the flap 30 can not only rotate freely relative to the oil cup 20, but also block the gap between the flap 30 and the oil cup 20, and prevent the oil drops on the inner side of the flap 30 or the oil guide plate 40 from dripping from the gap between the flap 30 and the oil cup 20 to the table top.

The two ends of the end surface of the turning plate 30 near to the end of the oil cup 20 may be provided with chamfers, and the end of the end surface near to the oil guide plate 40 may be provided with a first chamfer, which may be a chamfer angle or a rounded corner. The first chamfer reduces the radius of rotation of one end of the turning plate, which is close to the oil guide plate 40, relative to the rotation axis, and when the turning plate 30 rotates from bottom to top relative to the oil cup 20, the first chamfer enables the turning plate 30 not to collide with the edge of the oil cup 20 easily.

The end of the end surface facing away from the oil guide plate 40 may be provided with a second chamfer, which may be a rounded corner or a chamfer. The second chamfer reduces the radius of rotation of one end of the turning plate, which is away from the oil guide plate 40, relative to the rotation axis, and when the turning plate 30 rotates from top to bottom relative to the oil cup 20, the second chamfer also makes the turning plate 30 not easy to collide with the edge of the oil cup.

Referring to fig. 6 and 7, the end of the oil guide plate 40 facing away from the oil cup 20 may be provided with a connection plate 50, the connection plate 50 is attached to the flap 30, and when the flap 30 is in an open state, oil droplets generated during cooking are adhered to the connection plate 50 and the inner side of the oil guide plate 40, and only the inner side of the flap 30 close to the rotation axis is adhered to the oil droplets. When the turning plate 30 is in the retracted state, oil drops on the inner side of the turning plate 30 flow to the inner side of the connecting plate 50, and then the oil drops on the inner side of the connecting plate 50 flow to the oil guide plate 40 and flow into the oil cup 20 along the oil guide plate 40, so that the oil drops are prevented from polluting the table top.

The connecting plate 50 can be integrally arranged with the oil guide plate 40, so that no gap exists between the connecting plate 50 and the oil guide plate 40, and compared with the split arrangement of the connecting plate 50 and the oil guide plate 40, the oil can be prevented from dripping into the gap between the connecting plate 50 and the oil guide plate 40, and the cleaning of the oil adhered to the inner sides of the connecting plate 50 and the oil guide plate 40 is facilitated.
