[0033] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific implementation of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed for protection in the present invention.

[0034] refer to Figure 1-3 The present embodiment provides a guide plate mounting structure for a range hood, comprising a smoke collecting hood 1, a guide plate 2 and a hook assembly (not shown in the figure). The smoke collecting hood 1 has a smoke collecting cavity 10 which is recessed inward and open downward, an air inlet 11 is arranged at the top of the smoke collecting cavity 10, and a rear cavity wall of the smoke collecting cavity 10 constitutes a first mounting surface 12.

[0035] The guide plate 2 is arranged in the smoke collecting chamber 10 and below the air inlet 11. The guide plate 2 has a first end 21 and a second end 22 arranged opposite to each other. In this embodiment, the first end 21 is the rear end or lower end of the guide plate 2, and the second end 22 is the front end or upper end of the guide plate 2. Further, in order to facilitate the discharge of oil stains on the guide plate 2 and prevent the guide plate 2 from accumulating oil, the guide plate 2 is arranged from back to front and tilted upward. In addition, at least one oil leakage port 211 is provided at the rear end of the guide plate 2, so as to facilitate the discharge of oil stains on the top of the guide plate 2 through the oil leakage port 211.

[0036] The first end 21 is detachably connected to the first mounting surface 12 via at least one hook assembly. In this embodiment, the first end 21 is detachably connected to the first mounting surface 12 via two hook assemblies so that the rear end of the guide plate 2 can be detachably mounted on the smoke hood 1 in a stably and reliably manner. The cam 322 is a substantially parallelogram of the first and second projections on the first and second projections on the first and second projections on the second surfaces 321 of the second cam 32. The cam 322 is a substantially parallelogram of the first and second projections on the first and second projections on the second surfaces 321 of the second cam 32.

[0037] Furthermore, the fixing seat 32 is arranged above the guide plate 2, and the hook 31 is installed on the top of the first end 21 of the guide plate 2 and arranged close to the first mounting surface 12. In this way, the entire hook assembly is hidden at the top of the guide plate 2 and is not exposed on the outside or bottom of the guide plate 2, making the whole machine more beautiful and tidy.

[0038] Further, the hook 31 and / or the fixing seat 32 are made of plastic, preferably POM. In the present embodiment, the fixing seat 32 is made of POM, and the hook 31 is made of alloy material, so that it can be ensured that no friction noise and wear occur when the guide plate 2 is installed and rotated.

[0039] refer to Figure 1-2 and Figure 4-7 Further, the hook 31 includes a base 311 and a connecting arm 312, and the base 311 is fixedly installed on the top of the first end 21. The connecting arm 312 is arranged above the base 311 and its fixed end is fixedly connected to the base 311. In this embodiment, the base 311 and the fixed end of the connecting arm 312 are integrally formed, and the free end of the connecting arm 312 is inserted into the card slot 322 backwards and abuts or fits with the bottom of the limiting portion 321. At this time, the free end of the connecting arm 312 is limited and fixed between the limiting portion 321 and the card slot 3221, which effectively prevents the rear end of the guide plate 2 from rotating further upward and automatically falling off and scratching the smoke hood 1.

[0040] Furthermore, the hook 31 also includes a rotating shaft 313, and the rotating shaft 313 is fixedly provided at the free end of the connecting arm 312, and the rotating shaft 313 and the connecting arm 312 are enclosed to form a "T" or "L" shape. In the present embodiment, the rotating shaft 313 and the free end of the connecting arm 312 are integrally formed, and the two are enclosed to form a "T" shape. The rotating shaft 313 is inserted into the slot 322, and its opposite ends are respectively abutted or gap-fitted with the opposite side walls of the slot 322. In this way, the rotating shaft 313 cooperates with the opposite side walls of the slot 322 to limit the left and right movement of the connecting arm 312 in the slot 322, and at the same time, the contact area between the limiting portion 321 and the hook 31 is increased, and the reliability of the connection between the hook 31 and the fixing seat 32 is further improved.

[0041] It is particularly noted that the rotating shaft 313 can be omitted. In this case, in order to prevent the connecting arm 312 from moving left and right in the slot 322, the width of the free end of the connecting arm 312 in the left and right direction can be increased, or the width of the slot 322 in the left and right direction can be reduced, so that the free end of the connecting arm 312 is just matched with the slot 322. Of course, the width of the limiting portion 321 in the left and right direction can also be increased. In this case, even if the connecting arm 312 moves left and right in the slot 322, the limiting portion 321 can still limit and fix the free end of the connecting arm 312 in the slot 322, effectively preventing the connecting arm 312 from rotating upward and automatically leaving the slot.

[0042] refer to Figure 4-5 Furthermore, the hook assembly further includes a bracket 33. The end of the hook 31 away from the fixing seat 32 is provided with a concave cavity 3111 opening toward the guide plate 2.

The first end 21 of the guide plate 2 is connected and fixed to the hook 31 through the bracket 33, so that the hook 31 is fixedly installed on the top of the first end 21 of the guide plate 2.

[0043] The bracket 33 is in the shape of an inverted "Ω", including a "U"-shaped bottom plate and two side plates. The bottom plate is fixed to the top of the first end 21 by bonding or welding, and the two side plates are formed by bending the upper ends of the opposite side walls of the bottom plate outward. Screw holes 3112 are respectively provided at the left and right ends of the top of the base 311, and the screw holes 3112 are connected to the concave cavity 3111. During installation, fasteners (such as screws) are used to penetrate the screw holes from top to bottom and fasten them to the side plates of the bracket 33, so that the hook 31 is detachably fixed to the side plates of the bracket 33 through the fasteners.

[0044] refer to Figure 1-2 and Figure 7-8Furthermore, the lower end of the limiting portion 321 extends downward into the slot 322 to reduce the distance between the limiting portion 321 and the free end of the hook 31, thereby reducing the installation rotation space of the hook 31, and effectively ensuring that the free end of the hook 31 is reliably limited and fixed in the slot 322 by the limiting portion 321. In this embodiment, a lower guide surface 3211 is formed at the bottom of the limiting portion 321, and an upper guide surface 3212 is formed on a side of the limiting portion 321 away from the first installation surface 12. The lower guide surface 3211 and the upper guide surface 3212 both extend from the hook 31 toward the first installation surface 12 and are arranged to be inclined upward, and the inclination of the upper guide surface 3212 is greater than the inclination of the lower guide surface 3211. Therefore, through the cooperation between the upper guide surface 3212 and the lower guide surface 3211, the free end of the hook 31 can be quickly disassembled and assembled in the slot 322. In this embodiment, the lower guide surface 3211 is not only used for guiding, but also can be used to press the free end of the hook 31 to prevent the free end of the hook 31 from rotating upward.

[0045] Furthermore, the upper end surface of the slot 322 extends from the first mounting surface 12 toward the hook 31 and is arranged to be tilted downward, so that the upper end surface of the side slot wall 3222 of the slot 322 is arranged to be tilted downward from the back to the front, and the upper end surface of the front slot wall 3221 of the slot 322 is lower, so that it is more convenient to guide the free end of the hook 31 to be inserted into the slot 322. In addition, in order to save materials and facilitate demoulding, a notch 323 arranged corresponding to the limiting portion 321 is provided on the bottom surface of the slot 322, and the notch 323 connects the inside and outside of the slot 322.
