In a specific implementation, the bearing member 110 can be an L-shaped plate structure which is integrally formed on the inner side of the back plate 103.

[0058] According to an embodiment of the present application, the first oil guide plate 104 is detachably assembled in the rack 100. Figure 10 An assembly schematic view of the first oil guide plate and the rack 100 is shown, Figure 11 An enlarged schematic view of the A of the range hood is shown, Figure 10 For the purpose of clear display, Figure 10 The back plate 103 of the rack 100 is omitted. In combination with Figure 10 and Figure 11In the embodiment, the rack 100 further comprises two side plates 112, which are oppositely connected to the length direction of the back plate 103, and the two side plates 112 and the back plate 103 form a U-shaped structure. The first oil guide plate 104 is assembled between the two side plates 112, and the length direction of the first oil guide plate 104 is slightly smaller than the size between the two side plates 112. The side of the first oil guide plate 104 facing the side plate 112 is connected with a second flange 111, which can be integrally formed with the first oil guide plate 104. The second flange 111 extends downward of the first oil guide plate 104 and is attached to the inner side of the side plate 112 on the same side.

In another embodiment, the second flange 111 can extend upward of the first oil guide plate 104, which is not limited in the present application.

[0059] Figure 12 The structure diagram of another view of Figure 1 is shown, in order to show clearly, Figure 12 the back plate 103 of the rack 100 is omitted. In combination with Figure 12 , according to an embodiment of the present application, the second side of the first oil guide plate 104 is higher than the first side, i.e. the front side of the first oil guide plate 104 is higher than the back of the first oil guide plate 104, and the first oil guide plate 104 is inclined to the front side of the rack 100 to ensure the internal space of the rack 100. In the embodiment, the slope of the first oil guide plate 104 can be 20-30°.

[0060] In combination with Figure 12 , according to an embodiment of the present application, the range hood comprises a fan assembly 200 arranged in the rack 100, and the fan assembly 200 comprises a fan housing 201 provided with an air inlet 202 facing the back (back plate 103) of the rack 100.

The second side (front side) of the first oil guide plate 104 of the present application is arranged above the air inlet 202, so as to prevent the airflow from escaping above the first oil guide plate 104 and forming oil droplets on the top surface of the first oil guide plate 104.

[0061] Combination Figure 11 And Figure 12 According to an embodiment of the present application, the rack 100 further comprises a top plate 113, which is arranged above the fan housing 201, the top plate 113 is connected to the top of the back plate 103 and the two side plates 112, and the second side (front side) of the first oil guide plate 104 abuts on the bottom of the top plate 113 to avoid the airflow generated when the range hood is working from escaping through the gap between the second side of the first oil guide plate 104 and the bottom of the top plate 113.

[0062] Combination Figure 11 And Figure 12 According to an embodiment of the present application, the second side (front side) of the first oil guide plate 104 is provided with a third flange 114, the third flange 114 is bent upwards from the first oil guide plate 104, the third flange 114 is arranged horizontally, and the third flange 114 abuts on the bottom of the top plate 113 to ensure that there is no gap between the second side of the first oil guide plate 104 and the bottom of the top plate 113, thereby avoiding the airflow generated when the range hood is working from escaping through the gap between the second side of the first oil guide plate 104 and the bottom of the top plate 113, in addition, the third flange 114 can also be provided with a bolt hole to connect the third flange 114 with the top plate 113 through a bolt, thereby improving the reliability of the assembly of the first oil guide plate 104 in the rack 100.

[0064] According to another embodiment of the present application, the first oil guide plate 104 can also be integrally formed on the back of the rack 100, or connected to the back of the rack 100 by clamping or other means, which is not limited in the present application.

[0065] Based on the same design idea, the present application also provides a range hood, which comprises the above-mentioned rack 100, through the arrangement of the first oil guide plate 104, the phenomenon that the airflow generated when the range hood is running escapes through the hanging hole 105 of the back plate 103 of the rack 100 and drips on the cooking bench can be prevented, and through the additional flanges around the first oil guide plate 104, it is ensured that the airflow will not escape from the gap between the first oil guide plate 104 and the rack 100, thereby avoiding the oil droplets on the top surface of the first oil guide plate 104 to improve the user experience, which has good practicability.

[0066] In the related art, the air outlet of the fan assembly 200 of the range hood extends to the air outlet 102 provided on the top plate 113 of the rack 100 through a pipeline, and the air outlet 102 is connected to the air exhaust pipeline through the adapter 116, so that the airflow generated when the range hood is running is discharged from the air exhaust pipeline. However, the air outlet 102 of the range hood and the adapter 116 are usually fixedly connected by screws, which causes the air outlet 102 of the top plate 113 of the rack 100 to be easily deformed, resulting in poor sealing effect between the air outlet 102 of the rack 100 and the air exhaust pipeline, and the air outlet 102 of the rack 100 is prone to oil leakage.

[0067] Based on the above technical problems, the rack 100 provided by the present application aims to at least prevent the air outlet 102 of the top plate 113 of the rack 100 from being easily deformed, resulting in poor sealing effect between the air outlet 102 of the rack 100 and the air exhaust pipeline, and the air outlet 102 of the rack 100 is prone to oil leakage.

A connector 115 is connected to the edge of the exhaust vent 102 on the top plate 113, and an adapter 116 is connected to it. That is, the adapter 116 is connected to the top of the top plate 113 of the rack 100 via the connector 115, which strengthens the edge of the exhaust vent 102 on the top plate 113 and prevents deformation of the exhaust vent 102 on the top plate 113 to a certain extent. Furthermore, because the adapter... The sealing part 118 at the bottom of the connector 116 is interference-fitted into the vent 101 of the top plate 113. Through the interaction between the top plate 113 and the connector 116, deformation of the sealing part 118 of the connector 116 and the vent 101 of the top plate 113 can be prevented, thereby improving the sealing effect between the connector 116 and the connector 115 and avoiding oil leakage caused by deformation of the connector 116 and the exhaust vent 102 of the top plate 113. It has good practicality.
