[0036] 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.

[0037] The present application proposes a housing member embodiment for a range hood, such as Figure 1 and 2 As shown, the rear side wall 6 of the housing is configured to be suitable for being close to the wall 1 on which the hook 3 is fixed. The rear side wall 6 is provided with a hanging hole 9 suitable for being hung on the hook 3. When the hanging hole 9 is hung on the hook 3, the range hood is hung on the wall 1. Figure 7 and 8 shown.

[0038] The rear side wall 6 is integrally formed with a guide slope 7. Figure 1 and 2 As shown. The guide slope 7 is configured to guide the hook 3 to slide from bottom to top relative to the guide slope 7 and move toward the hanging hole 9 and finally insert into the hanging hole 9 when the hanging hole 9 is hung on the hook 3. In other words, during the installation operation of hanging the range hood on the wall 1, the guide slope 7 is suitable for guiding the hook 3 to move toward the hanging hole 9 until the hanging hole 9 is inserted to realize the hanging of the range hood on the wall 1. The setting of the guide slope 7 can improve the hanging installation efficiency of the range hood at a lower cost. It should be noted here that "guiding the hook 3 to move toward the hanging hole 9" is a figurative expression of relative motion. In fact, during the installation operation of hanging the range hood on the wall 1, it is the hanging hole 9 that moves, and the hook 3 fixed to the wall 1 is stationary. Specifically, during the installation operation of hanging the range hood on the wall 1, it is the range hood that moves, and the rear side wall 6 and its hanging hole 9 move with the range hood.

[0039] The guide slope 7 is located below the hanging hole 9. Figure 1 and 2 When the hook 3 is inserted into the hanging hole 9, that is, the hanging hole 9 is hung on the hook 3, the range hood is hung on the wall 1. Figure 7 and 8 Specifically, when the hook 3 is inserted into the hanging hole 9, the rear side wall 6 of the housing member is pressed against the wall 1, and the guide inclined surface 7 extends obliquely from the front to the back and downward toward the wall 1.

[0040] The top edge of the guide slope 7 coincides with the lower edge of the hanging hole 9. Figure 1 and 2 Thus, during the installation operation of hanging the range hood on the wall 1, the hook 3 first touches the bottom edge of the guide slope 7, as shown in FIG. Figure 5 and 6 Then, the range hood is moved down, and the hook 3 is moved up relative to the guide slope 7 until the hook 3 is separated from the top edge of the guide slope 7 and inserted into the hanging hole 9 to hang the range hood on the wall 1, as shown. Figure 7 and8 shown.

[0041] The rear side wall 6 is integrally formed by stamping a metal plate. The rear side wall 6 is integrally formed with a vertically arranged load-bearing wall body 8. A hanging hole 9 is arranged on the load-bearing wall body 8. Specifically, the hanging hole 9 is a through hole formed by cutting the load-bearing wall body 8. The outer surface of the load-bearing wall body 8 is connected to the guide slope 7 located below it. It should be explained here that "the outer surface of the load-bearing wall body 8 is connected to the guide slope 7 located below it" is a figurative expression. In fact, the load-bearing wall body 8 and the guide slope 7 are an integral part. Specifically, a fold is formed by stamping the corresponding metal plate, and the fold is the connection between the outer surface of the load-bearing wall body 8 and the guide slope 7. The outer surface of the load-bearing wall body 8 is located above the fold, and the guide slope 7 is located below the fold. Figure 1 and 2 shown.

[0042] The outer surface of the load-bearing wall 8 forms an obtuse angle with the guide slope 7, such as Figure 1 and 2 When the hook 3 is inserted into the hanging hole 9, the bottom edge of the guide slope 7 is against the wall 1, as shown in FIG. Figure 7 and 8 As shown, the obtuse angle formed by the outer surface of the load-bearing wall 8 and the guide inclined surface 7 opens toward the wall surface 1 .

[0043] The rear side wall 6 is integrally formed with a groove opening toward the wall 1; in other words, when the hook 3 is inserted into the hanging hole 9, the groove opens toward the wall 1. The groove is in the shape of a long strip, such as Figure 1 As shown. The groove is formed by punching the rear side wall 6 inwards; specifically, "punching inwards" can be figuratively understood as punching in the direction of the interior of the range hood. When the rear side wall 6 is punched inwards to form the groove, the above-mentioned "crease" is also formed.

[0044] The hanging hole 9 is arranged at the bottom of the groove. Figure 1 and 2 As shown. The bottom of the groove is vertically arranged. The bottom of the groove is the above-mentioned load-bearing wall 8. The guiding inclined surface 7 extends obliquely from the bottom edge of the groove bottom to the lower groove edge of the groove; specifically, when the hook 3 is inserted into the hanging hole 9, the guiding inclined surface 7 extends obliquely from the bottom edge of the groove bottom from the front to the back and downward toward the wall surface 1 to the lower groove edge of the groove, as shown in FIG. Figure 7 and 8 As shown, the range hood is located in front of the wall 1. The obtuse angle formed by the outer surface of the load-bearing wall 8 and the guide inclined surface 7 is arranged in the groove.

[0045] When the hook 3 is inserted into the hanging hole 9, the groove edge of the groove is close to the wall 1, and the hook 3 is completely placed in the groove. Figure 7 and 8Specifically, the hook 3 passes through the opening of the groove and is placed in the groove. It should be noted that the setting of the groove can play the role of reinforcing ribs, improve the load-bearing effect of the load-bearing wall 8, and make the cooperation between the hanging hole 9 and the hook 3 more stable.

[0046] When the hook 3 is inserted into the hanging hole 9, the upper hole edge of the hanging hole 9 is placed on the hook 3. Figure 8 As shown, the hook 3 can lift the range hood, thereby hanging the range hood on the wall 1. It should be noted that the outer convex portion is formed by punching the upper edge of the hanging hole 9 outward, such as Figure 1 , 2 , 6 and 8, it plays the role of reinforcing ribs, so that the upper hole edge of the hanging hole 9 and the hook 3 cooperate more firmly. Specifically, "outward pressing" can be figuratively understood as pressing in the direction of the outside of the range hood.

[0047] There are two hanging holes 9. The two hanging holes 9 are symmetrically arranged and are respectively arranged at the left and right ends of the rear side wall 6 of the housing. When the hook 3 is inserted into the hanging hole 9, the two hanging holes 9 are located at the same height. Figure 1 It is a partial structural cross-sectional view of only the hanging hole 9 provided at the left end of the rear side wall 6 of the shell member among the two hanging holes 9. As for the specific structure of the hanging hole 9 provided at the right end of the rear side wall 6 of the shell member, the structure of the hanging hole 9 provided at the left end of the rear side wall 6 of the shell member can be referred to.

[0048] The number of hooks 3 is also two. The two hooks 3 correspond to the two hanging holes 9 one by one. Specifically, the two hooks 3 are integrally formed on a hanger 2. The hanger 2 is made by stamping a long strip of metal plate. Figure 4 The hanger 2 is provided with a plurality of mounting holes for screws to pass through to fix the hanger 2 to the wall 1. When the hanger 2 is fixed to the wall 1, the rear wall of the hanger 2 is close to the wall 1, and the two hooks 3 extend obliquely from the back to the front and upward.

[0049] The present application also proposes an embodiment of a range hood, comprising a centrifugal fan 10, a fume collecting hood 4, a housing 5, an electrical box 11 and a duct seat 12. Figure 3 , 5As shown in and 7. The centrifugal fan 10 is arranged in the casing 5; specifically, the centrifugal fan 10 is arranged in the inner cavity of the casing 5. The smoke collecting hood 4 is suspended below the casing 5. The smoke collecting hood 4 is provided with a smoke collecting chamber. The smoke collecting chamber is configured to be suitable for gathering the oil smoke airflow and guiding the oil smoke airflow to flow into the inner cavity of the casing 5. The electrical box 11 and the air duct seat 12 are both arranged on the top wall of the casing 5. The air duct seat 12 is suitable for connecting to the air inlet port of the exhaust pipe. The exhaust port of the exhaust pipe is connected to the common flue. The casing 5 is the above-mentioned shell member embodiment. It should be noted that the rear side wall 6 is integrally stamped and formed from a metal plate; the metal plate is also integrally stamped and formed into the top wall of the casing 5, as shown in FIG. Figure 1 shown.

[0050] When cooking on the stove, the range hood is started, and the centrifugal fan 10 runs to generate negative pressure, forming an oil fume airflow. The smoke collecting chamber of the smoke collecting hood 4 gathers the oil fume airflow and guides the oil fume airflow into the inner cavity of the casing 5, and then flows through the air duct seat 12 and the exhaust pipe in sequence, and then is discharged into the public flue.

[0051] When hanging the range hood on the wall 1, first, fix the bracket 2 to the wall 1 with screws, and place the range hood in front of the wall 1 so that the rear side wall 6 of the housing of the range hood faces the wall 1. Figure 3 Then, keep the rear side wall 6 of the range hood housing member facing the wall 1, and move the range hood upward and backward toward the hook 3, so that the guide slope 7 is higher than the hook 3; then, move the range hood downward, and let the hook 3 contact the rear side wall 6 of the range hood housing member and slide along the outer surface of the rear side wall 6 until the hook 3 contacts the bottom edge of the guide slope 7, as shown in FIG. Figure 5 and 6 Then, continue to move the range hood downward, the hook 3 slides along the guide slope 7 until the hook 3 is inserted into the hanging hole 9 to achieve the range hood hanging on the wall 1, such as Figure 7 and 8 shown.

[0052] The components of different embodiments may be combined with each other in any feasible manner to achieve the purpose of this application.

[0053] The above are only optional embodiments of some implementation scenarios of the present application. It should be noted that, for ordinary technicians in this technical field, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application without departing from the technical concept of the present application also fall within the protection scope of the present application.
