[0034] Reference Figures 1 to 3According to the first embodiment of the utility model, the housing structure of the range hood includes a housing body 100, the housing body 100 is provided with an inner cavity 100a, the front side of the housing body 100 is provided with an opening 100b communicating with the inner cavity 100a, the bottom wall of the inner cavity 100a includes a bottom plate 110, an oil guide groove 111 is provided on the bottom plate 110, the inner walls around the oil guide groove 111 are inclined to extend to the bottom wall of the oil guide groove 111, and the bottom wall of the oil guide groove 111 is provided with two oil outlet holes 112. Therefore, through the guiding effect of the inclined inner wall of the oil guide groove 111, the oil on the bottom plate 110 can flow smoothly to the oil outlet holes 112 on the bottom wall of the oil guide groove 111 and enter the oil cup of the range hood, reducing the oil residue on the bottom plate 110, which is conducive to the cleaning of the inner cavity 100a in the later stage. In addition, since the residual oil on the bottom plate 110 is reduced, when the oil cup of the range hood is removed for cleaning, the situation where the oil drips from the oil outlet 112 onto the kitchen stove and pollutes the environment can be reduced.

[0035] It should be noted that, in a specific implementation process, only one oil outlet hole 112 may be provided, or three or more oil outlet holes 112 may be provided.

[0036] Reference Figure 1 and Figure 2 The bottom plate 110 is horizontally arranged around the oil guide groove 111 to facilitate installation of the oil cup, so that the periphery of the oil cup fits with the bottom plate 110 around the oil guide groove 111, thereby ensuring that the oil cup is firmly installed and reducing the gap between the oil cup and the bottom plate 110, thereby reducing the leakage of oil odor.

[0037] Reference Figure 1 , Figure 2 , Figure 4 According to some embodiments of the utility model, the oil outlet hole 112 is circular, and the peripheral wall of the oil outlet hole 112 extends downward to form a tapered flange 113, and the tapered flange 113 protrudes relative to the lower side of the bottom plate 110. By setting the oil outlet hole 112 to be circular and setting the tapered flange 113 protruding toward the peripheral wall of the oil outlet hole 112, the problem of oil hanging on the oil outlet hole 112 can be solved, and the setting of the oil guide groove 111 reduces the residual oil on the bottom plate 110, thereby effectively reducing the situation of oil dripping from the oil outlet hole 112 when the oil cup of the range hood is removed.

[0038] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, the side wall of the oil guide groove 111 protrudes downward relative to the bottom plate 110 to form a tapered step 114. Therefore, in the specific production process, the oil guide groove 111 can be formed on the bottom plate 110 by a stamping process, and the tapered step 114 is also formed when the oil guide groove 111 is formed. The above arrangement facilitates production and reduces manufacturing costs.

[0039] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, the bottom wall of the inner cavity 100a includes an inclined plate 120, and the bottom plate 110 is connected to the rear wall of the inner cavity 100a through the inclined plate 120, so that the oil on the back of the inner cavity 100a can flow smoothly into the oil guide groove 111 on the bottom plate 110 through the guidance of the inclined plate 120. In addition, when the front-to-back width of the lower end of the inner cavity 100a is large, due to the setting of the inclined plate 120, the width of the bottom plate 110 does not need to be the same as the front-to-back width of the lower end of the inner cavity 100a, which is conducive to controlling the width of the bottom plate 110 and reducing the oil residue on the bottom plate 110.

The setting of the second folded edge 116 can guide the oil stains that fall on the second folded edge 116 to flow back into the inner cavity 100a.

[0041] It is conceivable that, in some embodiments, a filter is provided at the opening 100b, and the oil stains generated on the filter can flow onto the second folded edge 116 and be guided into the inner cavity 100a by the second folded edge 116, thereby reducing the situation where the oil stains flow to the outer surface of the box body 100.

[0042] It is conceivable that, in some embodiments, a panel that can be opened and closed is provided at the opening 100b. During the operation of the range hood, the panel is opened to allow the external oil smoke to be drawn into the inner cavity 100a by the wind cabinet. After the range hood is finished working, the panel is closed. At this time, the oil stains generated on the inner surface of the panel will flow to the second folded edge 116 and be guided into the inner cavity 100a by the second folded edge 116, thereby reducing the situation where the oil stains flow to the outer surface of the box body 100.

[0043] Reference Figure 1 and Figure 3 According to some embodiments of the utility model, a wind cabinet installation hole 131 is opened on the top wall of the inner cavity 100a, and a baffle 132 is extended upward from the peripheral wall of the wind cabinet installation hole 131.
