Specific embodiments

[0042] The following will Figures 1-6 further describe the present application in detail with reference to the attached

[0043] The embodiment of the present application discloses a downdraft range hood. Referring to Figure 1 , a downdraft range hood is arranged inside the cooking range 1, and it includes an air suction port 11 and an air suction duct 12 opened on the cooking range 1 tabletop. The air suction port 11 vertically penetrates the cooking range 1 tabletop, and the air suction duct 12 inside the cooking range 1 body is connected to the air suction port 11. Thus, the oil fume and smoke on the cooking range 1 tabletop are sucked into the air suction duct 12 and discharged from the air suction duct 12.

[0044] Referring to Figure 1 and Figure 2 , a plurality of stoves 13 are distributed on the cooking range 1, and the stoves 13 are distributed on multiple sides of the air suction port 11 to surround the air suction port 11. Relevant personnel cook on the stoves 13, and the air suction port 11 sucks away the oil fume generated by cooking on the stoves 13. The stoves 13 are arranged inside the tabletop, and a rack plate 2 is laid above the cooking range 1 corresponding to the stoves 13 and the air suction port 11. The rack plate 2 is horizontally arranged on the tabletop to prevent the internal components of the stoves 13 from being exposed to the outside.

[0045] Referring to Figure 1 and Figure 3An oil guide groove 21 is provided on the surface of the rack plate 2 outside the air inlet 11. The oil guide groove 21 is provided between the air inlet 11 and the stove 13. The oil guide groove 21 is door-shaped, and both ends extend to the edge of the rack plate 2, so that the oil guide groove 21 completely surrounds the air inlet 11. The oil guide groove 21 is used to protect the oil on the stove 1 from entering the air inlet 11. The bottom wall of the oil guide groove 21 is an arc surface to prevent the oil from accumulating in the side corners of the oil guide groove 21. The two ends of the oil guide groove 21 connected to the edge of the rack plate 2 are tilted downward, so that the oil entering the oil guide groove 21 slides out of the oil guide groove 21 by itself under the action of gravity, and it is also convenient for users to clean up when the oil accumulates.

[0046] Reference Figure 1 and Figure 4 A closed groove 22 is provided inside the plate body of the frame plate 2, and the closed groove 22 is provided horizontally. A closed plate 23 is slidably connected inside the closed groove 22. The plate surface of the closed plate 23 is not less than the area of the air suction port 11. The closed plate 23 can slide along the closed groove 22 to the air suction port 11 to close the air suction port 11; to facilitate the sliding of the closed plate 23, in this embodiment, the closed groove 22 is penetrated by one side edge of the frame plate 2, and a push-pull block 24 is formed on one side edge of the closed plate 23. One end of the push-pull block 24 extends out of the closed groove 22 and extends out of the interior of the frame plate 2. Therefore, the user can slide the closed plate 23 along the closed groove 22 to the air suction port 11 to close it by tossing the push-pull block 24.

[0047] Reference Figure 3 and Figure 5 Two slide grooves 25 are provided at each end of the air inlet 11, and a total of four slide grooves 25 are provided in parallel. A slider 26 is slidably connected in each slide groove 25. The length of the slide groove 25 is not less than the length of the end of the air inlet 11, so that the slider 26 can slide along the slide groove 25 to both sides of the end of the air inlet 11. An adjusting rod 27 is hinged on the sliders 26 of the two slide grooves 25 in the middle part of the four slide grooves 25, and an adjusting rod 27 is hinged on the sliders 26 of the two slide grooves 25 in the two side parts. The two adjusting rods 27 have different lengths. The two adjusting rods 27 are door-shaped and rotate around the hinged part to any reasonable angle. In the initial state, both adjustment rods 27 are in a horizontal state, and two adjustment grooves for accommodating the adjustment rods 27 are provided on the surface of the stove 1 corresponding to the adjustment rods 27, and each adjustment groove is in a door-shaped groove shape suitable for the corresponding adjustment rods 27; a soft film 28 is fixedly connected to the bottom wall of the adjustment rod 27, and one end of the soft film 28 is fixedly connected to the rod body of the adjustment rod 27. As the adjustment rod 27 rotates, the soft film 28 gradually unfolds, and when the rotation angle of the adjustment rod 27 is an obtuse angle, that is, the adjustment rod 27 is in an inclined state, the soft film 28 is fully unfolded. Therefore, when only one side of the stove 13 is turned on, the adjustment rod 27 on the other side rotates to make the air inlet 11 face different sides.

[0048] Reference Figure 5 and Figure 6, to fix the adjusting rod 27 after rotation, a receiving groove 29 is formed on the slider 26 corresponding to the adjusting rod 27, and the side wall of the receiving groove 29 is inclined so that the adjusting rod 27 abuts against the inclined side wall.

[0049] Look back Figure 1 , to endow the air suction port 11 with basic and preliminary object filtering ability, a grille is formed inside the cooking range 1 corresponding to the air suction port 11 to prevent large-particle objects from entering the inside of the air suction port 11.

[0050] The implementation principle of a down-draft range hood according to an embodiment of the present application is as follows: when only one or the stove 13 on one side of the air suction port 11 is turned on, the adjusting rod 27 on the opposite side can be rotated and the slider 26 on the opposite side can be slid to open the soft film 28 and change the orientation of the air suction port 11 to enhance the air suction ability of the air suction port 11.

[0051] When the down-draft range hood is not operating, the sliding closing plate 23 can be slid to close the air suction port 11.

[0052] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
