[0026] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0027] This utility model discloses a smoke hood. Please refer to [link / reference]. Figures 1 to 4 The present invention proposes a range hood comprising a housing 1, an exhaust device 2, and an oil cup 3. The housing 1 has a first part extending from front to back and a second part extending from top to bottom. The first part has a bottom plate 11, and the second part has a front plate 12. There is a gap between the rear edge of the bottom plate 11 and the upper edge of the front plate 12, forming a first air intake a. The housing 1 has a smoke collection chamber located on the upper side of the bottom plate 11 and the rear side of the front plate 12. The exhaust device 2 draws in oil fumes through the first air intake a and discharges the oil fumes from the smoke collection chamber. The oil cup 3 is connected to the housing 1 and is used to collect the oil discharged from the smoke collection chamber.

[0028] In this embodiment, the second part is located below the first part, and the rear end of the first part is connected to the top end of the second part. The smoke collection chamber is partially located inside the first part and partially located inside the second part. The range hood also includes an exhaust box installed above the first part, which is connected to the smoke collection chamber. An exhaust device 2 is installed inside the exhaust box, and an exhaust vent is provided at the top of the exhaust box. The exhaust device 2 is used to provide the power required for the range hood to extract oil fumes. After the exhaust device 2 is activated, it will generate negative pressure in the smoke collection chamber, causing air to flow. The oil fumes in the kitchen will be drawn into the smoke collection chamber from the first air intake a, and then flow further to the exhaust box before being discharged from the exhaust vent.

[0029] The oil cup 3 can be connected to the bottom of the second part. The opening of the receiving cavity of the oil cup 3 faces upward and is connected to the smoke collection cavity. The oil accumulated in the smoke collection cavity and the oil dripping from the exhaust device 2 into the smoke collection cavity will flow to the oil cup 3 under the action of gravity, so as to realize the oil cup 3 to receive and collect the oil.

[0030] The base plate 11 and the front plate 12 together constitute the panel portion of the housing 1. The base plate 11 and the front plate 12 are respectively processed and formed. The first air intake a is formed by the gap between the rear edge of the base plate 11 and the upper edge of the front plate 12. In this way, the base plate 11 and the front plate 12 forming the first air intake a can be made of different materials, thereby making the appearance and function of the base plate 11 and the front plate 12 more diversified. For example, the front plate 12 can be made of glass to provide a certain aesthetic effect; or, the front plate 12 can be movable relative to the base plate 11 to control the opening and closing of the first air intake a or to adjust the opening degree of the first air intake a. This improves the appearance and performance of the range hood.

[0031] The smoke hood of this utility model, such as Figure 4 As shown, the rear edge of the base plate 11 is located behind the upper edge of the front plate 12 in the front-rear direction, and the downward projection of the rear edge of the base plate 11 falls into the smoke collection chamber.

[0032] The base plate 11 extends downwards from front to back. The oil dripping from the exhaust device 2 onto the base plate 11 will flow backwards. When the oil flows to the rear edge of the base plate 11, it will drip down. Since the downward projection of the rear edge of the base plate 11 falls into the smoke collection chamber, the oil dripping from the rear edge of the base plate 11 will also drip into the smoke collection chamber. In this way, the oil in the smoke collection chamber can be prevented from dripping out of the first air intake a or dripping onto the front side of the front plate 12, so as to ensure the oil leakage prevention effect of the range hood.

[0033] The smoke hood of this utility model, such as Figures 3 to 4 As shown, the front panel 12 has a notch 121 that extends upward to the upper edge of the front panel 12. The width of the part of the first air intake a that is aligned with the notch 121 in the vertical direction is greater than the width of the part that is aligned with the two sides of the notch 121.

[0034] The gap between the front plate 12 and the bottom plate 11, together with the notch 121, constitutes the first air intake a. The notch 121 can increase the air intake area of ​​the first air intake a, thereby increasing the air intake flow of the first air intake a, so as to improve the extraction efficiency of oil fumes.

[0035] The smoke hood of this utility model, such as Figure 1 As shown, a second air intake b is also provided on the front panel 12, located in the lower half of the front panel 12. When the range hood is working, negative pressure is generated at both the first air intake a and the second air intake b. Under the action of negative pressure, the fumes rush towards the front panel 12. Some of the fumes are drawn in by the second air intake b, while some of the fumes flow upward along the front panel 12 and are drawn in by the first air intake a. The second air intake b is connected to the smoke collection chamber. The second air intake b can work in conjunction with the first air intake a to increase the air intake volume of the range hood per unit time, thereby improving the efficiency of fume extraction.

[0036] The smoke hood of this utility model, such as Figure 1 As shown, the air intake volume of the second air intake b is greater than that of the first air intake a. The air intake area of ​​the second air intake b is greater than that of the first air intake a, so that the air intake volume of the second air intake b is greater than that of the first air intake a. When the range hood is working, the fumes rushing towards the front panel 12 are mainly drawn in by the second air intake b, while the upward-flowing oil is drawn in by the first air intake a, thus ensuring the effective extraction of fumes.

[0037] The smoke hood of this utility model, such as Figures 1 to 4 As shown, the housing 1 includes a top plate 13, a back plate 14, a side plate 15, a bottom plate 11, and a front plate 12. The rear side of the top plate 13 is connected to the upper side of the back plate 14. The left and right sides of the top plate 13 are connected to the upper side of the side plate 15. The rear side of the side plate 15 is connected to the corresponding side of the back plate 14. The left and right sides of the bottom plate 11 are connected to the corresponding side plate 15. The left and right sides of the front plate 12 are connected to the corresponding side plate 15. An oil cup 3 is connected to the lower end of the housing 1. The downward projection of the lower edge of the front plate 12 falls into the oil cup 3. The top plate 13, back plate 14, side plate 15, bottom plate 11 and front plate 12 together form a smoke collection chamber. Some of the oil fumes entering the smoke collection chamber will adhere and accumulate on the back of the front plate 12, forming oil flowing downwards. Since the downward projection of the lower edge of the front plate 12 falls into the oil cup 3, the oil flows downwards along the front plate 12 to the lowest point and then flows into or drips into the oil cup 3, thereby collecting the oil adhering to the front plate 12 and preventing the oil from overflowing.

[0038] The smoke hood of this utility model, such as Figure 4As shown, a connecting plate 122 is provided at the bottom of the front plate 12, and an oil receiving groove 16 is provided at the bottom of the back plate 14. The connecting plate 122 is connected to the bottom of the oil receiving groove 16, and the oil receiving groove 16 is connected to the oil cup 3. The connecting plate 122 is connected to the lower back of the front plate 12, and the front end of the oil receiving groove 16 is connected to the connecting plate 122. Thus, the connecting plate 122 can support the oil receiving groove 16 and improve the structural stability of the oil receiving groove 16. The oil cup 3 is located below the oil receiving groove 16. An oil dripping hole is opened at the bottom of the oil receiving groove 16. Most of the oil adhering and accumulating in the smoke collection chamber will flow to the oil receiving groove 16 under the action of gravity, and then flow to the oil cup 3 through the oil dripping hole to achieve oil collection.

[0039] The smoke hood of this utility model, such as Figure 3 and Figure 5 As shown, the front edge of the side plate 15 extends to the opposite side along its outline with an extension surface 151. The extension surface 151 includes a first segment extending from front to back, a second segment extending from top to bottom, and a third segment connecting the first and second segments. The second segment is located below the first segment, and the third segment connects the upper end of the second segment to the rear end of the first segment. The first segment corresponds to the first part of the housing 1, and the second segment corresponds to the second part of the housing 1. The extension surface 151 can abut and limit the sides of the front plate 12 and the bottom plate 11, thereby making the overall structure of the housing 1 more stable and compact.

[0040] The smoke hood of this utility model, such as Figures 1 to 3 As shown, the range hood also includes side baffles 4, which are located on both sides of the housing 1 and connected to the corresponding side plates 15. There are two side baffles 4, which are respectively connected to the two side plates 15. The area between the two side baffles 4 is the smoke collection area. The side baffles 4 play a certain role in blocking and guiding the fumes, preventing the fumes from moving directly away from the smoke collection area, thereby prolonging the residence time of the fumes near the air inlet and allowing the fumes to be fully drawn into the air inlet.

[0041] By directly connecting the side baffle 4 to the side plate 15, the side baffle 4 can be installed on the housing 1. Since the side baffle 4 is directly connected to the side plate 15 rather than to the front plate 12 or bottom plate 11 of the housing 1, the shear force on the front plate 12 or bottom plate 11 can be reduced, preventing the front plate 12 or bottom plate 11 from easily deforming. As for the side plate 15, connecting the side baffle 4 to the side plate 15 does not increase the shear force on the side plate 15, and therefore it will not easily deform. Thus, the structural stability of the housing 1 of the range hood is improved.

[0042] The smoke hood of this utility model, such as Figures 3 to 5As shown, the front edge of the side plate 15 is provided with a mounting groove 152, and the side baffle 4 is connected to the mounting groove 152. The mounting groove 152 extends along the front edge of the side plate 15, and the mounting groove 152 can increase the mating area between the side baffle 4 and the side plate 15, thereby improving the connection stability between the side baffle 4 and the side plate 15. The groove wall of the mounting groove 152 can also play a positioning role for the side baffle 4, preventing the side baffle 4 from easily shifting.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
