[Specific implementation method]

[0034] In order to make the purpose, scheme and beneficial effects of the present application more clear, the present application is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0035] See also Figure 1 A range hood includes a detachable wind cabinet 1 and a fume hood 2. The wind cabinet 1 can refer to a cabinet with a fan installed inside, or a smoke exhaust passage connecting the fan and the fume hood 2, which is not limited here. In one embodiment of the present application, the wind cabinet 1 with a fan installed inside is taken as an example for description:

[0036] like Figure 2 and Figure 4 As shown, the wind cabinet 1 is formed by a front panel 11, two side panels 12, a back panel 13 and a cover plate 14, wherein the front panel 11, the two side panels 12 and the back panel 13 form a cylindrical structure, the cover plate 14 is arranged on the top of the cylindrical structure, and the bottom of the cylindrical structure forms an air inlet 3. A smoke outlet 4 is arranged at a position corresponding to the air inlet 3 on the upper part of the smoke hood 2, and the air inlet 3 is plugged with the smoke outlet 4 to install the smoke hood 2 and the wind cabinet 1 together.

[0037] Specifically, Figure 3 and Figure 5 As shown, the air inlet 3 is provided with an elastic connector 5, and the smoke outlet 4 is provided with a clearance hole 41 corresponding to the elastic connector 5. During the plugging process, the elastic connector 5 is elastically deformed and enters the clearance hole 41 to achieve the plugging and fixing of the air inlet 3 and the smoke outlet 4. Compared with the prior art that requires the use of tools to install the wind cabinet 1 and the smoke hood 2 together, the embodiment of the present application has a simple structure and is easy to operate.

[0038] According to an exemplary embodiment of the present application, the smoke outlet 4 is provided with a guide surface 42 corresponding to the elastic connector 5, and the guide surface 42 presses against the elastic connector 5 during the plugging process to cause it to deform elastically. During installation, the smoke outlet 4 is aligned with the air inlet 3, and the smoke hood 2 moves from bottom to top to achieve connection with the wind cabinet 1, and the guide surface 42 begins to squeeze the elastic connector 5 during the upward movement. The clearance hole 41 is arranged adjacent to the guide surface 42, which is conducive to the elastic connector 5 entering the clearance hole 41 after leaving the guide surface 42.

[0039] According to an exemplary embodiment of the present application, Figure 7 and Figure 8 As shown, the elastic connector 5 includes a limit end 51, and the limit end 51 includes a first position protruding from the side wall of the air inlet 3, and a second position substantially flush with the side wall of the air inlet 3. The first position is the initial position of the limit end 51, and during the plug-in process, as the guide surface 42 moves upward, the limit end 51 is pressed by the guide surface 42 and moves toward the side wall of the air inlet 3 until it is flush with the side wall, i.e., reaches the second position. The limit end 51 is flush with the side wall of the air inlet 3, which is conducive to the continued upward movement of the smoke hood 2. Then, the positioning hole 41 comes to a position flush with the limit end 51, and the limit end 51 is no longer pressed. Figure 8 That is, it shows that the limit end 51 is in this position and is about to enter the clearance hole 41. Finally, the limit end 51 returns to the first position. Figure 7 As shown, the connection between the smoke hood 2 and the wind cabinet 1 is realized.

[0040] According to an exemplary embodiment of the present application, Figure 3 As shown, the elastic connecting member 5 includes a supporting member 52, a return spring 53 and a sliding rod 54. The supporting member 52 is fixedly connected to the side wall of the air inlet 3 to form a spring cavity for accommodating the return spring 53 and the sliding rod 54. The side wall of the air inlet 3 is provided with a first through hole (not shown) for the sliding rod 54 accommodated in the spring cavity to pass through. The limiting end 51 is located on the sliding rod 54, and the limiting end 51 can pass through the first through hole and protrude from the side wall of the air inlet 3. When the limiting end 51 is pressed by the guide surface 42, the sliding rod 54 moves and compresses the return spring 53.

[0041] Furthermore, the support member 52 is in a "J" shape, including a top plate 521, waist plates 522 located on both sides of the top plate 521, and lower edge wings 523 extending outward from the bottom of the waist plate 522, and the lower edge wings 523 are provided with mounting holes 524 for connecting with the side walls of the air inlet 3. The spring cavity is surrounded by the top plate 521, the waist plate 522 and the side walls of the air inlet 3. The support member 52 of the "J" shape structure is conducive to maintaining the stability of the spring cavity space.

[0042] Furthermore, a boss 541 is provided on the slide bar 54, and the return spring 53 is sleeved on the slide bar 54 and located between the boss 541 and the top plate 521. The slide bar 54 compresses the return spring 53 through the boss 541. In addition, the top plate 521 is provided with a second through hole 525 corresponding to the first through hole for the slide bar 54 to pass through, and the first through hole and the second through hole 525 together limit the slide bar 54 in a horizontal plane.

[0043] According to an exemplary embodiment of the present application, Figure 5As shown, the guide surface 42 includes a guide proximal end 421 located at the side wall of the smoke outlet 4 and a guide distal end 422 away from the side wall of the smoke outlet 4. Specifically, the guide surface 42 originates from the guide proximal end 421 and extends upward and in a direction away from the side wall of the smoke outlet 4. During the plugging process, the guide surface 42 moves upward with the smoke outlet 4, and the guide distal end 422 and the guide proximal end 421 contact the limit end 51 respectively.

[0044] Further, the guide proximal end 421 is located directly above the clearance hole 41. Thus, when the guide proximal end 421 leaves the height where the limiting end 51 is located, the clearance hole 41 comes to the height and allows the limiting end 51 to pass through.

[0045] Furthermore, in the movement direction of the limiting end 51, the distance between the guide distal end 422 and the side wall of the smoke outlet 4 is not less than the distance between the limiting end 51 and the side wall of the air inlet 3 when the limiting end 51 is in the first position. Therefore, when the guide distal end 422 reaches or approaches the height of the limiting end 51, it can press the limiting end 51 and make it move toward the side wall of the air inlet 3.

[0046] According to an exemplary embodiment of the present application, Figure 2 As shown, the elastic connector 5 is located inside the air inlet 3. Here, it means that the main body of the elastic connector 5 is located inside the air inlet 3, which is beneficial to reduce the influence of the connection structure on the appearance of the range hood.

[0047] According to an exemplary embodiment of the present application, Figure 2 As shown, the wind cabinet 1 includes a front panel 11, two side panels 12, a back panel 13 and a cover plate 14, and the elastic connecting member 5 is located at the bottom of the side panels 12 and the back panel 13, realizing the installation connection between the wind cabinet 1 and the smoke hood 2 from at least three sides.

[0048] Further, refer to Figure 4 and Fig.10 The side wall of the smoke outlet 4 corresponding to the back plate 13 is provided with an L-shaped flange 43 extending toward the center of the smoke outlet 4, the back guide surface 42' is located on the L-shaped flange 43, the clearance hole 41 is located directly below the back guide surface 42', and the distance between the clearance hole 41 and the side wall of the smoke outlet 4 corresponding to the back plate 13 allows the limit end 51 to be accommodated. Fig. 9 and Fig.11 As shown, after the plugging is completed, the limiting end 51 will not protrude from the outside of the back plate 13, and the back plate 13 and the wall can be installed seamlessly.

[0049] According to an exemplary embodiment of the present application, since the control panel of the range hood is usually integrated on the smoke hood 2, the wind cabinet 1 and the smoke hood 2 are also connected through an electric coupler (not shown) and a water connection joint (not shown), and the electric coupler and the water connection joint include two parts, one part of the electric coupler and the water connection joint is arranged on the wind cabinet 1, and the other part of the electric coupler and the water connection joint is arranged on the smoke hood 2.

[0050] The components of different embodiments may be combined with each other in any feasible manner to achieve the purpose of this application.

[0051] It should be noted that the present application should not be understood as being limited to the above-described implementation methods, but should be understood as covering all possible implementations determined by the claims of the present application in combination with the disclosure of the specification. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present application without departing from the content of the technical solution of the present application shall fall within the protection scope of the technical solution of the present application.
