[0024] 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.

[0025] Example 1

[0026] refer to Figure 1-3 This embodiment provides a flow guide mechanism, including a panel 1 and an oil guide plate 2, wherein the panel 1 is preferably made of glass or stainless steel, and is provided with an opening 11 for allowing oil smoke to pass through. The oil guide plate 2 is fixedly mounted on the back of the panel 1 and located below the opening 11, and is used to guide the fluid on the back of the panel 1 to the inside of the smoke hood, wherein the fluid includes oil or cleaning water.

[0027] Furthermore, drainage recesses 211 that are recessed downward and used for fluid to pass through are respectively provided on the left and right sides of the upper end of the oil guide plate 2. In this way, when the fluid flows down from the back of the fluid panel 1, the fluid will expand to the left and right along the oil baffle plate after flowing to the position of the oil guide plate 2. When the fluid flows into the drainage recess 211 of the oil guide plate 2, because the bottom position of the drainage recess 211 is relatively low, the fluid will flow out to the lower end of the oil guide plate 2 along the drainage recess 211. The oil guide plate 2 will guide the fluid to the inside of the smoke hood of the range hood, and converge to the oil cup or water cup of the range hood along the internal structure. It can be seen that by using the drainage recess 211 of the oil guide plate 2 to converge the fluid to the inside of the smoke hood of the range hood, the fluid is prevented from flowing out from both sides of the oil guide plate 2, the problem of automatic cleaning leakage of the range hood is solved, and the user experience is improved.

[0028] In this embodiment, the oil guide plate 2 includes a mounting section 21 and a guide section 22. The mounting section 21 is fixedly mounted on the lower end of the back of the panel 1 by bonding and is in contact with the back of the panel 1. When the panel 1 is made of stainless steel, the mounting section 21 can be fixed on the lower end of the back of the panel 1 by welding and is in contact with the back of the panel 1. The left and right ends of the mounting section 21 are respectively provided with drainage recesses 211. The upper end of the guide section 22 is fixedly connected to the lower end of the mounting section 21 and is arranged at an obtuse angle. At this time, the guide section 22 is arranged at an acute angle with the back of the panel 1. The guide section 22 is used to guide the fluid flowing out of the drainage recess 211 to the inside of the smoke hood.

[0029] Furthermore, the angle θ between the guide section 22 and the mounting section 21 is 110 to 170°, preferably 150±10°. Figure 2 , and the guide section 22 is formed by the lower end of the mounting section 21 being bent toward the oblique rear. The guide recess 211 is in a "V" shape, referring to Figure 3 Of course, the drainage recess 211 may also be designed to be in any of the shapes of "U", "W" or "mountain".

[0030] refer to Figure 1-4 In this embodiment, the guide mechanism also includes two fixed brackets 3, which are fixedly installed on the back of the panel 1 and are respectively located on the left and right outer sides of the oil guide plate 2. The oil guide plate 2 is abutted or gap-matched with each fixed bracket 3. Through the two fixed brackets 3, the panel 1 can be detachably installed on the front of the smoke hood.

[0031] Furthermore, a convex edge 31 extending outward is fixedly provided on one side of the fixed bracket 3 close to the oil guide plate 2, and the convex edge 31 is located above the oil guide plate 2, so that the convex edge 31 can prevent the fluid on the back of the panel 1 from flowing to the two sides of the oil guide plate 2, and at the same time facilitate the fluid to be directed to the oil guide plate 2. Furthermore, an upper flange 311 bent backward is fixedly provided at the free end of the convex edge 31, so as to strengthen the strength of the fixed bracket 3 and further improve the water blocking effect.

[0032] Furthermore, a lower flange 32 bent backward is fixedly provided at the lower end of the fixed bracket 3 near the oil guide plate 2, and the lower flange 32 is in contact with or gap-fitted with the oil guide plate 2 to enhance the strength of the fixed bracket 3 and improve the water-blocking effect. In addition, two hooks 33 arranged at intervals in the upper and lower directions are provided on the side of the fixed bracket 3 away from the oil guide plate 2, so as to facilitate the detachable installation of the panel 1 on the front of the smoke hood.

[0033] The present embodiment also provides a range hood, comprising a smoke hood and a guide mechanism as described above, wherein the panel 1 is detachably mounted on the smoke hood, and the oil guide plate 2 is used to guide the fluid on the back of the panel 1 to the inside of the smoke hood to solve the problem of water leakage during automatic cleaning of the range hood.

[0034] Example 2

[0035] refer to Figure 5 The difference between this embodiment and the embodiment 1 is that the structure of the oil guide plate 2 is different. Specifically, a plurality of water retaining portions 212 extending upward are integrally formed on the top of the oil guide plate 2. More specifically, water retaining portions 212 extending upward are integrally formed on the left and right sides of the top of the mounting section 21. A drainage recess 211 for fluid to pass through is formed between adjacent water retaining portions 212. In this way, when the fluid flowing down from the back of the panel 1 flows to the position of the oil guide plate 2, it will expand to the left and right along the oil retaining plate. Due to the blocking effect of the water retaining portions 212, the fluid cannot flow through the two sides of the oil retaining plate 2, and can only flow out to the lower end of the oil guide plate 2 along the drainage recess 211 between the two adjacent water retaining portions 212, that is, along the drainage recess 211 between the two adjacent water retaining portions 212 to the drainage section 22. The drainage section 22 will guide the fluid to the inside of the smoke collecting hood of the range hood, thereby preventing the fluid from flowing out from the two sides of the oil guide plate 2 and solving the problem of automatic cleaning leakage of the range hood.

[0036] In other embodiments, a plurality of water retaining portions 212 extending upward may be evenly spaced at intervals on the top of the oil guide plate 2, so that the upper edge of the oil guide plate 2 is wavy. In this case, once the fluid flows to the drainage recesses 211 between adjacent water retaining portions 212, it will not spread to the left and right along the oil retaining plate, but can only flow downward along the drainage recesses 211 to the diversion section of the oil guide plate 2. Of course, the left and right ends of the oil guide plate 2 may also be integrally bent backward to form water retaining ribs to prevent the fluid from flowing to both sides of the guide plate 2 when flowing through the oil guide plate 2.

[0037] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
