DETAILED DESCRIPTION

[0030] In order to make the purpose, scheme and beneficial effects of the present application more clear and obvious, the present application is further described below in combination with the drawings and preferred embodiments.

[0031] Referring to Figure 1 , a range hood includes a fan housing 1, a smoke collecting hood 2 arranged below the fan housing 1, and a wire 3 extending from outside the fan housing 1 to inside the fan housing 1. Referring to Figure 3 , the fan housing 1 includes a wiring passage 10 allowing the wire 3 to enter inside the fan housing 1.

[0032] Thus, the problem that oil accumulated on the inner wall of the fan housing 1 or the wire 3 flows out of the wiring passage 10 after the range hood is used for a period of time, causing pollution of the smoke collecting hood 2 or other components, is caused.

[0033] ​​​To this end, the present application makes certain improvements to the wiring channel 10 to limit the flow of oil from the fan housing 1 to the hood 2.

[0034] According to an exemplary embodiment of the present application, as shown in Figure 3 The fan housing 1 further comprises a fixed frame 11 for connecting the hood 2, which is located or at least partially located at the outer periphery of the bottom edge 12 of the fan housing 1. Optionally, the bottom edge 12 is provided with a horizontal outward flange 121, and the fixed frame 11 is fixed to the flange 121. The fixed frame 11 is formed with a recess 110 corresponding to the position of the wire 3, and the recess 110 and the bottom edge 12 together form the above-mentioned wiring channel 10 at this position.

[0035] According to an exemplary embodiment of the present application, as shown in Figure 3 The recess 110 comprises a bottom plate 111 and a barrier wall 112 fixedly connected to the bottom plate 111 and limiting the flow of oil out of the recess 110 in a direction away from the interior of the fan housing 1. When oil from the inner wall of the fan housing 1 or the wire 3 accumulates on the bottom plate 111, the barrier wall 112 should be able to prevent the oil from further flowing to the hood 2 or other components located outside the fan housing 1.

[0036] Generally, as shown in Figure 5 The wire 3 passes through the top of the barrier wall 112 and the bottom plate 111 in turn when entering the interior of the fan housing 1. In order to prevent oil from the interior of the fan housing 1 from flowing out of the recess 110 along the wire 3, the height of the barrier wall 112 should be designed to be higher than any position of the wire 3 when passing through the bottom plate 111 when the wire 3 is lapped on the top of the barrier wall 112. It should be noted that the passage through the bottom plate 111 here can mean that the wire 3 contacts the bottom plate 111, or passes through from above the bottom plate 111 without contact.

[0037] Further, the bottom plate 111 gradually decreases in the direction close to the interior of the fan housing 1, which can make the oil flowing to the bottom plate 111 move inward and downward, through the oil screen, oil guide plate and other components to the oil cup of the range hood.

[0038] According to an exemplary embodiment of the present application, the recess 110 gradually decreases in the direction close to the interior of the fan housing 1, which can make the oil flowing to the recess 110 move inward and downward, through the oil screen, oil guide plate and other components to the oil cup of the range hood.

[0039] According to an exemplary embodiment of the present application, as shown in Figure 2As shown, the fan casing 1 includes a front plate 13 and side plates 14 on both sides of the front plate 13, and the wiring channel 10 is located below the front plate 13. In a general range hood, the control panel is usually located on the front side of the hood 2 and is electrically connected to the electrical box through the wire 3, which enters the inside of the fan casing 1 from a position close to the front plate 13 and enters the electrical box above, which helps to reduce the amount of consumables and structural complexity; further, as shown, Figure 7 As shown, a blocking surface 141 is provided at a position close to the front plate 13 below the side plate 14 to restrict the flow of oil to the wiring channel 10, which can prevent oil from the side plate 14 from entering the wiring channel 10.

[0040] According to an exemplary embodiment of the present application, as shown, Figure 5 The fan casing 1 further includes a wire fixing member 113 rotatably connected to the fixed frame 11, and the wire fixing member 113 has a first position and a second position. When installing the wire 3, the wire fixing member 113 is rotated to the first position, at which time the wiring channel 10 is in a fully open state, facilitating the wire 3 to enter the inside of the fan casing 1; after installation is complete, the wire fixing member 113 is rotated to the second position and partially blocks the wiring channel 10 in the wiring direction, so that the wire 3 is tightly fixed; the wire fixing member 113 gradually lowers in a direction close to the inside of the fan casing 1, which can make the oil flowing to the wire fixing member 113 move inward and downward to the oil cup of the range hood through the oil screen, oil guide plate and other components.

[0041] According to an exemplary embodiment of the present application, as shown, Figure 1 The hood 2 includes an upper cover 21 and a lower cover 22, and the fan casing 1 passes through the upper cover 21 and is connected to the lower cover 22 through the fixed frame 11; the wire 3 is drawn from the control panel on the front side, passes through the inside of the hood 2 formed by the upper cover 21 and the lower cover 22, and reaches the connection between the fixed frame 11 and the bottom edge of the front plate 13, at which the fixed frame 11 is recessed downward to form or at least partially form the wiring channel 10.

[0042] According to an exemplary embodiment of the present application, the range hood further includes an oil screen, an oil guide plate and an oil cup located below the fan casing 1 for receiving oil from the inside of the fan casing 1. Based on the design of the present application, the oil in the wiring channel 10 will flow inward and downward to the oil screen and the oil guide plate, and eventually be collected in the oil cup, improving the ease of cleaning of the range hood.

[0043] The components of different embodiments can be combined with each other in any feasible manner to achieve the purpose of the present application.

[0044] It should be noted that the present application should not be limited to the above-described embodiments, but should be understood to cover all possible implementations within the scope of the present application as defined by the claims in conjunction with the description. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application, without departing from the content of the present application, shall fall within the protection scope of the present application.
