[0048] 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.

[0049] An embodiment of a range hood proposed in the present application includes a body and a decorative hood. The decorative hood is configured to be placed on the body from top to bottom. The body includes a casing 9, a smoke hood 10 and an oil cup 14 arranged in sequence from top to bottom. A fan is arranged in the casing 9. The casing 9 and the smoke hood 10 are connected and fixed together. When the fan is running, negative pressure is generated to form an oil fume airflow, and the smoke hood 10 guides the oil fume airflow upward into the casing 9 and then discharged into the public flue. The grease filtered out by the casing 9 and the smoke hood 10 eventually flows into the oil cup 14 suspended at the bottom of the smoke hood 10.

[0050] The decorative cover includes a front plate 1, a left side plate 2 and a right side plate 3. The front plate 1 is connected and arranged between the left side plate 2 and the right side plate 3. The decorative cover is U-shaped as a whole. Figures 3 to 12 As shown. The decorative cover is provided with a hook portion, which is configured to be suitable for hooking on the convex part of the range hood when the decorative cover is assembled on the range hood, so as to prevent the decorative cover from moving forward and leaving the range hood. In other words, if the decorative cover has a tendency to move forward due to various reasons such as vibration, the hook portion is hooked on the convex part of the range hood, so that the decorative cover cannot move forward, thereby preventing the decorative cover from moving forward and leaving the range hood. The convex part is provided on the machine body.

[0051] The hook portion includes a left hook portion 4 and a right hook portion 5, such as Figure 3 and 10 As shown. The left hook portion 4 is arranged at the rear end edge of the left side plate 2. The rear end edge of the left side plate 2 extends in the vertical direction. The rear end edge of the left side plate 2 is bent toward the inner cavity of the decorative cover to form the left hook portion 4. The left hook portion 4 is open toward the front plate 1. The left hook portion 4 is U-shaped.

[0052] The right hook portion 5 is disposed at the rear end edge of the right side plate 3. The rear end edge of the right side plate 3 extends in the vertical direction. The rear end edge of the right side plate 3 is bent toward the inner cavity of the decorative cover to form the right hook portion 5. The right hook portion 5 is open toward the front plate 1. The right hook portion 5 is U-shaped, as shown in FIG. Fig.11 shown.

[0053] The convex part includes a left convex part 11 and a right convex part 12, such as Figure 1 As shown. The left protrusion 11 corresponds to the left hook 4 and matches with the left hook 4. The right protrusion 12 corresponds to the right hook 5 and matches with the right hook 5. When the decorative cover is placed on the body, if the decorative cover is moved forward, the left hook 4 is hooked on the left protrusion 11, and the right hook 5 is hooked on the right protrusion 12, thereby preventing the decorative cover from moving forward and leaving the range hood.

[0054] When the decorative cover is placed on the machine body, the housing 9 is partially placed in the inner cavity of the decorative cover and is covered and shielded by the decorative cover. Figure 5 Specifically, the housing 9 placed in the inner cavity of the decorative cover is covered and shielded by the decorative cover, so that in normal use, the housing 9 covered and shielded by the decorative cover is not visible to the user. The housing 9 is in the shape of a rectangular parallelepiped. The inner cavity of the decorative cover is adapted to the shape of the housing 9, as shown in FIG. Figure 5 and 6 shown.

[0055] The housing 9 includes an upper wall and a lower wall arranged in sequence from top to bottom. The lower wall is convex relative to the upper wall. A U-shaped step surface 13 is connected between the lower wall and the upper wall. Figures 1 to 3 It should be noted that the U-shaped step surface 13 is U-shaped as a whole, matching the U-shaped decorative cover.

[0056] The protrusion is integrally formed on the U-shaped step surface 13 and tilted upward from the U-shaped step surface 13. The left protrusion 11 is integrally formed at the left end of the U-shaped step surface 13. The right protrusion 12 is integrally formed at the right end of the U-shaped step surface 13. The decorative cover is configured to be suitable for Figure 3 When the decorative cover is placed on the machine body, the decorative cover is placed on the U-shaped step surface 13. At this time, the left hook 4 is hooked on the left protrusion 11, and the right hook 5 is hooked on the right protrusion 12. The upper wall of the housing 9 is placed in the inner cavity of the decorative cover and covered by the decorative cover, and the lower wall of the housing 9 is exposed. Figure 4 , 5 As shown in 6, the U-shaped step surface 13 is covered by the U-shaped decorative cover located above it, and the outer surface of the lower wall of the casing 9 is connected to the outer surface of the decorative cover, and a U-shaped connection seam is formed between the lower wall of the casing 9 and the decorative cover. Under normal use, the upper wall covered and blocked by the decorative cover is not visible to the user. The front panel 1 is located directly in front of the casing 9. In the horizontal direction from front to back, the front panel 1 blocks the upper wall of the casing 9. The left side panel 2 is located on the left side of the casing 9. In the horizontal direction from left to right, the left side panel 2 blocks the upper wall of the casing 9. The right side panel 3 is located on the right side of the casing 9. In the horizontal direction from right to left, the right side panel 3 blocks the upper wall of the casing 9.

[0057] The left protrusion 11 and the right protrusion 12 are both in the shape of inserts with their free ends extending upward. The left protrusion 11 is spaced apart from the housing 9 to form a first gap into which the free end of the left hook 4 is inserted. Figure 2 Specifically, when the decorative cover is placed on the machine body, the free end of the left hook portion 4 is placed in the first gap, and the left hook portion 4 is hooked on the left protrusion 11, as shown in FIG. Figure 8 shown.

[0058] The free end of the left protrusion 11 extends upward and away from the housing 9, so that the first gap is wide at the top and narrow at the bottom. Figure 2 As shown; thus, the free end of the left protrusion 11 is suitable for guiding the free end of the left hook 4 into the first gap, so as to realize the convenient installation of the decorative cover. Figure 2 As shown in the figure mark "T". The left protrusion 11 includes a vertically arranged first sheet and a free end extending from the top of the first sheet. The free end of the left protrusion 11 is bent at an angle α relative to the first sheet in a direction away from the housing 9; in other words, the position of the free end of the left protrusion 11 before bending and the position of the free end of the left protrusion 11 after bending form an angle α. α is an acute angle, preferably, α=5°. Before the free end of the left protrusion 11 is bent, it is also vertically arranged like the first sheet. When the decorative cover is placed on the body, the free end of the left hook 4 is hidden in the inner cavity of the decorative cover and is not visible to the user.

[0059] The right protrusion 12 and the left protrusion 11 are arranged in mirror symmetry with each other. A second gap is formed between the right protrusion 12 and the housing 9 for the free end of the right hook 5 to be placed in; specifically, when the decorative cover is placed on the body, the free end of the right hook 5 is placed in the second gap, and the right hook 5 is hooked on the right protrusion 12. The free end of the right hook 5, such as Fig.11 As shown by the reference numeral "P" in the figure. The free end of the right protrusion 12 extends obliquely upward in a direction away from the housing 9, so that the second gap is wide at the top and narrow at the bottom; thus, the free end of the right protrusion 12 is suitable for guiding the free end of the right hook 5 to be placed in the second gap, so as to realize the convenient installation of the decorative cover. The right protrusion 12 includes a second sheet body arranged vertically and a free end extending from the top of the second sheet body. The free end of the right protrusion 12 is bent at an angle β relative to the second sheet body in a direction away from the housing 9; in other words, the position of the free end of the right protrusion 12 before bending and the position of the free end of the right protrusion 12 after bending form an angle β. β is an acute angle, preferably, β=5°. Before the free end of the right protrusion 12 is bent, it is also arranged vertically like the second sheet body. When the decorative cover is placed on the body, the free end of the right hook 5 is hidden in the inner cavity of the decorative cover and is not visible to the user.

[0060] The bottom end of the left side plate 2 is bent toward the inner cavity of the decorative cover to form a left folded edge 6. When the decorative cover is placed on the body, the left folded edge 6 abuts against the outer wall of the housing 9. Figure 8 and 9 When the decorative cover is placed on the machine body, the left folded edge 6 abuts against the outer wall of the housing 9, which helps to reduce the swing of the decorative cover relative to the housing 9. It should be noted here that "abutting against the outer wall of the housing 9" can be directly abutting against the outer wall of the housing 9, or the distance between the left folded edge 6 and the outer wall of the housing 9 is small enough to reduce the swing of the decorative cover relative to the housing 9.

[0061] The bottom end of the right side plate 3 is bent toward the inner cavity of the decorative cover to form a right folded edge 7. When the decorative cover is placed on the machine body, the right folded edge 7 abuts against the outer wall of the housing 9. Fig.12 When the decorative cover is placed on the machine body, the right folded edge 7 abuts against the outer wall of the housing 9, which helps to reduce the swing of the decorative cover relative to the housing 9. It should be noted here that "abutting against the outer wall of the housing 9" can be directly abutting against the outer wall of the housing 9, or the distance between the right folded edge 7 and the outer wall of the housing 9 is small enough to reduce the swing of the decorative cover relative to the housing 9.

[0062] The bottom end of the front plate 1 is bent toward the inner cavity of the decorative cover to form a front fold 8. When the decorative cover is placed on the body, the front fold 8 abuts against the outer wall of the housing 9. Fig. 9 and 12When the decorative cover is placed on the machine body, the front fold 8 abuts against the outer wall of the housing 9, which helps to reduce the swing of the decorative cover relative to the housing 9. It should be noted here that "abutting against the outer wall of the housing 9" can be directly abutting against the outer wall of the housing 9, or the distance between the front fold 8 and the outer wall of the housing 9 is small enough to reduce the swing of the decorative cover relative to the housing 9.

[0063] The range hood embodiment is configured to be suitable for hanging on a wall, located above the stove, to exhaust the fumes generated when cooking on the stove. When the decorative cover is placed on the body, the U-shaped opening of the overall U-shaped decorative cover faces the wall. Specifically, the opening of the decorative cover is close to the wall, and the left hook 4 and the right hook 5 are close to the wall. The right protrusion 12 and the left protrusion 11 are also close to the wall.

[0064] The left hook portion 4 extends vertically from the top of the rear end edge of the left side plate 2 to the bottom of the rear end edge of the left side plate 2. Figure 3 The right hook portion 5 extends vertically from the top of the rear edge of the right side plate 3 to the bottom of the rear edge of the right side plate 3. Figure 3 It should be noted that if the left hook 4 is only provided at the bottom end of the rear edge of the left side plate 2, and the right hook 5 is only provided at the bottom end of the rear edge of the right side plate 3, the corresponding function can also be achieved, which is also feasible.

[0065] For example, Fig.13 As shown, the present application proposes another embodiment of a range hood, wherein the free end of the left protrusion 11 extends upwardly and away from the housing 9, so that the first gap is wide at the top and narrow at the bottom, and the bottom of the left protrusion 11 is adjacent to the housing 9. Since the bottom of the left protrusion 11 is adjacent to the housing 9, when the decorative cover is placed on the body, the free end of the left hook 4 is squeezed between the left protrusion 11 and the housing 9. The left protrusion 11 itself has a certain elasticity. The free end of the right protrusion 12 extends upwardly and away from the housing 9, so that the second gap is wide at the top and narrow at the bottom, and the bottom of the right protrusion 12 is adjacent to the housing 9. Since the bottom of the right protrusion 12 is adjacent to the housing 9, when the decorative cover is placed on the body, the free end of the right hook 5 is squeezed between the right protrusion 12 and the housing 9. The right protrusion 12 itself has a certain elasticity. Thus, when the decorative cover is placed on the machine body, the free end of the left hook 4 is squeezed between the left protrusion 11 and the machine housing 9, and the free end of the right hook 5 is squeezed between the right protrusion 12 and the machine housing 9, so that the decorative cover is more securely fixed. This embodiment focuses on the differences from the above embodiment, and the same and similar parts of this embodiment can be referred to the above embodiment.

[0066] For example, Figures 14 to 17As shown, the present application proposes another embodiment of a range hood, when the decorative hood is placed on the machine body, the decorative hood is placed on the top wall of the smoke hood 10. The convex piece is integrally formed on the top wall of the smoke hood 10 and tilts upward from the top wall of the smoke hood 10; specifically, the left convex piece 11 is integrally formed on the top wall of the smoke hood 10 and tilts upward from the top wall of the smoke hood 10, and the right convex piece 12 is integrally formed on the top wall of the smoke hood 10 and tilts upward from the top wall of the smoke hood 10. When the decorative hood is placed on the machine body, the housing 9 is completely placed in the inner cavity of the decorative hood and is covered and shielded by the decorative hood, as shown in FIG. Fig.17 As shown, therefore, in normal use, the entire housing 9 is covered and shielded by the decorative cover and cannot be seen by the user. This embodiment focuses on the differences from the above embodiment, and the same and similar parts of this embodiment can refer to the above embodiment.

[0067] The components of different embodiments may be combined with each other in any feasible manner to achieve the purpose of this application.

[0068] 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.
