Detailed implementation manners
[0026] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.
[0027] Embodiment 1
[0028] Referring to the attached Figures 1-8 drawings, a range hood includes a box body 1. A fan 4 is installed inside the box body 1, a smoke collecting hood 2 is installed at the bottom of the box body 1, and an oil net 3 is installed on the front side of the smoke collecting hood 2. The fan 4 is used to suck air from the oil net 3, the smoke collecting hood 2, and the box body 1 in sequence and discharge it from the upper end of the box body 1 (as shown by the arrows in Figure 4 and Figure 8 ). A separator 5 is fixedly installed inside the box body 1. The separator 5 divides the box body 1 into two spaces, a front side space and a rear side space. The fan 4 is installed in the front side space, and the air inlet of the fan 4 faces the rear side space of the box body 1.
[0029] It should be noted that by dividing the space inside the box body 1 into two spaces, a front side space and a rear side space (i.e., the two spaces on the left and right of the separator 5 in Figure 4 ), when air enters the inside of the box body 1, it can only flow from the rear side space into the fan 4 and will not enter the front side space, thus greatly reducing the situation of ineffective flow of air in the box body 1 and further reducing the loss of air volume.
[0030] Further, the spacer 5 includes a partition board 51. The upper and lower ends of the partition board 51 are respectively provided with an upper folding plate 52 and a lower folding plate 53. The upper folding plate 52 and the lower folding plate 53 are respectively installed on the upper side and the lower side of the box body 1.
[0031] It should be noted that both the upper folding plate 52 and the lower folding plate 53 are connected to the box body 1 by screws.
[0032] Further, a top plate cover 7 is installed on the top of the box body 1. The top plate cover 7 is provided with an air outlet for installing an air duct 8.
[0033] It should be noted that by providing the top plate cover 7, the components exposed at the upper end of the box body 1 can be covered for protection.
[0034] In this embodiment, as Figure 3 and Figure 4 shown, the front side of the box body 1 is an open structure, and a closing assembly is provided on the front side of the box body 1 for closing the open structure on the front side of the box body 1. Specifically, the closing assembly includes a U-shaped cover plate 11, and both sides of the U-shaped cover plate 11 are fixedly installed on the outer side walls on both sides of the box body 1.
[0035] It should be noted that the open structure on the front side of the box body 1 facilitates the installation of the fan 4. After the installation is completed, it is closed by the U-shaped cover plate 11.
[0036] In this embodiment, as Figure 2 shown, the side panels 21 on both sides of the smoke collecting hood 2 and the rear panel 22 at the rear of the smoke collecting hood 2 are inclined towards the rear side of the box body 1.
[0037] It should be noted that by adopting the above technical solution, the space inside the smoke collecting hood 2 can be reduced, so as to reduce the situation of the ineffective flow of air in the smoke collecting hood 2, thereby reducing the loss of air volume.
[0038] Embodiment Two
[0039] Different from Embodiment One, in this embodiment, as Figures 5-8 shown, the closing assembly includes a front plate 12 and a fixing plate 13. The fixing plate 13 is arranged inside the box body 1 and fixedly connected to the box body 1. The fixing plate 13 is also fixedly installed with the fan 4. The front plate 12 is fixedly installed at the position of the open structure on the front side of the box body 1.
[0040] It should be noted that by providing the fixing plate 13, on the one hand, it is installed with the box body 1, and on the other hand, it is installed with the fan 4, so as to improve the installation stability of the fan 4. The open structure on the front side of the box body 1 can be closed by the front plate 12.
[0041] Embodiment Three
[0042] Different from the first and second embodiments, in this embodiment, as Figures 5-8 shown, the side panels 21 on both sides of the smoke collecting hood 2 and the rear panel 22 at the rear of the smoke collecting hood 2 are vertically arranged. Air guide plates 6 are arranged on both sides inside the smoke collecting hood 2. The air guide plate 6 includes a lower guide plate 61, and the upper end of the lower guide plate 61 has an upper guide plate 62 which is bent towards the middle of the upper end of the smoke collecting hood 2. When air enters the inside of the smoke collecting hood 2 from the oil screen 3, it is located in the space between the two air guide plates 6.
[0043] It should be noted that arranging the side panel 21 and the rear panel 22 vertically can reduce dust dead corners when installed in the kitchen. However, this setting will increase the internal space of the smoke collecting hood 2 and cause ineffective air flow inside the smoke collecting hood 2. Therefore, two air guide plates 6 are provided to limit the actual air flow space inside the smoke collecting hood 2 between the two air guide plates 6, so as to reduce the air flow space inside the smoke collecting hood 2 and reduce the ineffective air flow situation.
[0044] The above embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation to the scope of the patent of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
