Description

[0001] This application is a divisional application of the invention patent application filed by the applicant on November 29, 2024, with application number "2024229504053" and title "Tobacco Machine". Technical Field

[0002] This utility model relates to the field of kitchen appliance technology, specifically to a range hood. Background Technology

[0003] When users cook, a large amount of oily fumes are generated. These fumes spread throughout the cooking space, polluting it. Cooks working in such a fume-filled environment will suffer health consequences from prolonged inhalation of these fumes. A range hood, located above the cooktop, is an appliance designed to remove these cooking fumes from the kitchen, providing a healthy cooking environment. Existing side-draft range hoods have side-draft vents on their suction panel, which are closer to the cooktop and can remove fumes more quickly. However, when stir-frying, the fumes are generated rapidly, and a large amount of fumes rushes towards the side-draft vents. Fumes that cannot be drawn in quickly escape upwards along the suction panel, affecting the range hood's fume purification effect and reducing the user experience. Utility Model Content

[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] Please see Figure 1 This utility model discloses a range hood, which includes a range hood body 1. The range hood body 1 has a front panel 11 and a top panel 12. The front panel 11 is arranged in the vertical direction and a fourth air intake 111 is provided on the front panel 11 in the horizontal direction. The top panel 12 is arranged in the front and back direction and a first air intake 121 is provided on the left and right sides of the top panel 12. The first air intake 121 is arranged in the front and back direction of the top panel 12. The fourth air intake 111 and the first air intake 121 are both connected to the smoke collection chamber 13 of the range hood body 1.

[0028] In this embodiment, the top side of the front panel 11 is connected to the rear side of the top plate 12. A smoke exhaust fan is installed in the smoke collection chamber 13. When the smoke exhaust fan is running, it can generate negative pressure at the fourth air intake 111 and the first air intake 121. The cooking fumes generated by the user are drawn into the smoke collection chamber 13 through the fourth air intake 111 and the first air intake 121, and are finally discharged by the smoke exhaust fan. The fourth air intake 111 is elongated and extends along the left and right directions of the front panel 11. There are two first air intakes 121, which are located near the left and right sides of the top plate 12, respectively, and both first air intakes 121 are elongated strips extending along the front and back directions.

[0029] First air inlets 121 are set on the left and right sides of the top plate 12 of the range hood, which enhances the air intake range on the left and right sides of the top plate 12. When the range hood is working, negative pressure is generated at both the fourth air inlet 111 and the first air inlet 121. The fourth air inlet 111 is closer to the stove. When the oil fumes are generated quickly, a large amount of oil fumes rush to the fourth air inlet 111. Some of the oil fumes are sucked into the smoke collection chamber 13 by the fourth air inlet 111. The oil fumes that cannot be sucked in by the fourth air inlet 111 will flow upward along the front panel 11. After the oil fumes flow to the top plate 12, they will flow to the front and left and right sides. Finally, they can be sucked into the smoke collection chamber 13 by the first air inlets 121 set on the left and right sides of the top plate 12. Since the first air inlets 121 extend in the front and back direction, the oil fumes can be continuously sucked in by the first air inlets 121 as they flow forward. In this way, the fumes flowing through the main body 1 of the range hood can be fully drawn into the fume collection chamber 13, reducing the escape of fumes and improving the fume extraction effect of the range hood, thus improving the user experience.

[0030] The smoke hood of this utility model, such as Figure 1 and Figure 2 As shown, a second air intake 122 is also provided on the top plate 12. The second air intake 122 is arranged along the left and right direction of the top plate 12 and is located between the two first air intakes 121. The second air intake 122 is connected to the smoke collection chamber 13 of the main body 1 of the range hood. The second air intake 122 is strip-shaped, and negative pressure can be generated at the second air intake 122 when the exhaust fan is running. After the oil fumes flow to the top plate 12, the oil fumes flowing forward between the fourth air intake 111 and the first air intake 121 can be sucked into the smoke collection chamber 13 by the second air intake 122 when they flow through it. In this way, the escape of oil fumes can be further reduced, thereby further improving the smoke extraction effect of the range hood.

[0031] The smoke hood of this utility model, such as Figure 1 and Figure 2As shown, the top plate 12 is also provided with a third air intake 123 located between the two first air intakes 121. There are two third air intakes 123. The dimensions of the two third air intakes 123 along the left and right directions of the top plate 12 are smaller than the dimensions of the second air intakes 122 along the left and right directions of the top plate 12. The two third air intakes 123 are located near the left and right ends of the top plate 12 and are located behind the second air intakes 122. The third air intakes 123 are strip-shaped, and negative pressure can be generated at the third air intakes 123 when the exhaust fan is running. The length of the third air intakes 123 is less than that of the second air intakes 122, which is equivalent to increasing the air intake area of ​​the portion of the second air intakes 122 corresponding to the left end and the portion corresponding to the right end of the top plate 12. After the fumes flow to the top plate 12, the fumes flowing forward between the fourth air intake 111 and the first air intake 121 first pass through the third air intake 123. Some of the fumes are drawn into the smoke collection chamber 13 by the third air intake 123. The fumes that cannot be drawn in by the third air intake 123 continue to flow forward and are eventually drawn into the smoke collection chamber 13 by the second air intake 122. In this way, the escape of fumes can be further reduced, thereby further improving the fume extraction effect of the range hood.

[0032] The smoke hood of this utility model, such as Figure 3 and Figure 4 As shown, a cavity is provided on the top plate 12, with the second air intake 122 and the third air intake 123 located within the cavity, and the first air intake 121 located on the portions of the top plate 12 on both sides of the cavity. The cavity can collect the oil fumes flowing to the top plate 12, increasing the difficulty for the oil fumes to escape from the top plate 12 and prolonging the time the oil fumes flow along the top plate 12, thereby providing sufficient time for the second air intake 122 and the third air intake 123 to fully draw the oil fumes into the smoke collection chamber 13. The cavity is located between the two first air intakes 121. If the oil fumes in the cavity flow out from the left and right sides, the two first air intakes 121 can promptly draw this portion of the oil fumes into the smoke collection chamber 13, further reducing the escape of oil fumes.

[0033] In some embodiments, such as Figure 1 As shown, there is one cavity, and there are one, two, or more second air inlets 122. One second air inlet 122 extends to both sides of the cavity in the left-right direction, with its left side extending to the left end of the corresponding third air inlet 123 and its right side extending to the right end of the corresponding third air inlet 123; or, two or more second air inlets 122 are arranged in the left-right direction of the cavity, with the left end of the leftmost second air inlet 122 extending to the left end of the corresponding third air inlet 123 and the right end of the rightmost second air inlet 122 extending to the right end of the corresponding third air inlet 123.

[0034] In one embodiment, there is one second air intake 122, which extends to both sides of the cavity along its width. The left end of the second air intake 122 is flush with the left end of one of the third air intakes 123, and the right end of the second air intake 122 is flush with the right end of the other third air intake 123. This improves the overall appearance of the main body 1 of the range hood and allows for a reasonable arrangement of the second air intake 122 and the third air intake 123, ensuring that the fumes flowing to the top plate 12 are fully drawn into the smoke collection chamber 13.

[0035] In another embodiment, such as Figure 1 As shown, there are two or more second air intakes 122, which are arranged along the width of the top plate 12. The leftmost second air intake 122 extends to the left end of the corresponding third air intake 123, and the rightmost second air intake 122 extends to the right end of the corresponding third air intake 123. Figure 1 As shown, taking two second air intakes 122 as an example, the left end of one second air intake 122 is flush with the left end of one of the third air intakes 123, and the right end of the other second air intake 122 is flush with the right end of the other third air intake 123. Since the length of the second air intake 122 is greater than the length of the third air intake 123, the ends of the two second air intakes 122 that are close to each other can be close to the middle of the cavity bottom plate. In this way, the appearance of the main body 1 of the range hood can be improved, and the distribution of the second air intakes 122 and the third air intakes 123 can be reasonably set to ensure that the oil fumes flowing to the top plate 12 are fully drawn into the smoke collection chamber 13.

[0036] In the smoke hood of this utility model, such as Figure 1 As shown, the top plate 12 is also provided with a lighting window 124, which is located on the front wall of the cavity. The main body 1 of the range hood also has an electrical control cavity 14, in which a lighting lamp 15 is installed. The lighting lamp 15 is installed in the electrical control cavity 14, and its lighting side is aligned with the lighting window 124. The lighting window 124 is set downwards, and the lighting lamp 15 is installed in the lighting window 124. The light emitted by the lighting lamp 15 can shine downwards through the lighting window 124, thereby illuminating the area where the user is located, providing auxiliary lighting for the user's cooking process, and thus improving the performance of the range hood.

[0037] In other embodiments, such as Figure 3 As shown, there are two cavities, and each cavity is provided with a second air inlet 122 and a third air inlet 123. The second air inlet 122 extends along the left and right direction of the cavity, and the third air inlet 123 is located near the left / right side of the left / right cavity and extends to the left / right side of the second air inlet 122.

[0038] Two cavities are distributed along the width of the top plate 12. These cavities can be defined as a left cavity and a right cavity. The third air intake 123 in the left cavity is close to the left wall of the left cavity, and the third air intake 123 in the right cavity is close to the right wall of the right cavity. The left end of the third air intake 123 in the left cavity is flush with the left end of the second air intake 122 in the left cavity. The right end of the third air intake 123 in the right cavity is flush with the right end of the second air intake 122 in the right cavity. By setting the number of cavities to two, the fumes can be diverted when they reach the top plate 12, preventing turbulent airflow when the fumes turn upon contact with the top plate 12. This allows the diverted fumes to be drawn more promptly and fully into the smoke collection chamber 13 by the second air intake 122 and the third air intake 123 in both cavities.

[0039] In the embodiments of the two cavities mentioned above, such as Figure 3 As shown, the top plate 12 is also provided with a lighting window 124, which is located between the two cavities. The main body 1 of the range hood also has an electrical control cavity 14, in which a lighting lamp 15 is installed. The lighting lamp 15 is installed in the electrical control cavity 14, and its lighting side is aligned with the lighting window 124. The lighting window 124 is set downwards, and the lighting lamp 15 is installed in the lighting window 124. The light emitted by the lighting lamp 15 can shine downwards through the lighting window 124, thereby illuminating the area where the user is located, providing auxiliary lighting for the user's cooking process, and thus improving the performance of the range hood.

[0040] In the smoke hood of this utility model, such as Figure 2 and Figure 4 As shown, the fourth air intake 111 is a concealed air intake. A notch is provided on the front panel 11, and a baffle plate 16 extends from the lower edge of the notch into the smoke collection chamber 13. The baffle plate 16 is inclined backward from bottom to top, and the height of the upper edge of the baffle plate 16 is not lower than the height of the upper edge of the notch. The gap between the upper edge of the baffle plate 16 and the upper edge of the notch forms the fourth air intake 111. In this range hood, the projection of the notch backward falls onto the baffle plate 16. When looking at the front panel 11 from the user's side, the user sees only the baffle plate 16 and cannot see the back panel of the smoke collection chamber 13 through the notch. Oil stains on the back panel of the smoke collection chamber 13 will not be visible to the user, ensuring the range hood's aesthetics and improving the user experience.

[0041] In this utility model of a smoke hood, the baffle plate 16 extends from the lower edge of the notch toward the inner side of the notch. The distance between the baffle plate 16 and the front panel 11 increases from the lower edge to the upper edge. A flow channel is formed between the baffle plate 16 and the flow section of the notch. The flow channel connects the notch and the fourth air intake 111. After the airflow flows into the notch, it first hits the baffle plate 16, then flows along the flow channel to the fourth air intake 111, and then flows into the smoke collection chamber 13 through the fourth air intake 111.

[0042] When the user looks at the notch on the front panel 11, the baffle 16 can block the user's view, preventing the user from directly seeing the back panel of the smoke collection chamber 13 through the notch, thus avoiding affecting the user's visual perception of the range hood. Since the baffle 16 is set to tilt backward from bottom to top, the gap between the upper edge of the baffle 16 and the upper edge of the air intake forms a hidden fourth air intake 111. After the oil fumes flow into the notch and hit the baffle 16, they can continue to flow upward through the fourth air intake 111 into the smoke collection chamber 13, thereby avoiding the baffle 16 affecting the process of oil fumes flowing into the smoke collection chamber 13 and ensuring the oil fume intake effect of the range hood.

[0043] The smoke hood of this utility model, such as Figure 2 and Figure 4 As shown, according to one embodiment of the present invention, the baffle plate 16 has connecting plates 17 on both sides. The connecting plates 17 are connected to the side edges of the corresponding sides of the notch. The connecting plates 17 are arc-shaped, and the upper edge of the connecting plates 17 is a first arc-shaped edge protruding in the direction away from the user side. There are two connecting plates 17, which are respectively provided at both ends of the baffle plate 16. Each connecting plate 17 connects the end side edge of the baffle plate 16 to the side edge of the notch. In this way, the baffle plate 16 and the front panel 11 can be visually connected as a whole to improve the appearance of the range hood. In addition, the connecting plates 17 can increase the connection position between the baffle plate 16 and the front panel 11 to improve the connection stability between the baffle plate 16 and the front panel 11. The side of the connecting plate 17 near the notch is a concave arc surface, and the upper edge of the connecting plate 17 forms a concave arc edge, which can maximize the distance between the upper edge of the connecting plate 17 and the upper edge of the notch, thereby increasing the flow area of ​​the fourth air intake 111 and improving the air intake volume of the fourth air intake 111.

[0044] The baffle plate 16 and the connecting plate 17 are integrally formed with the front panel 11. The front panel 11 is a sheet metal part, and both the baffle plate 16 and the connecting plate 17 are cut and stamped on the front panel 11. The connection between the connecting plate 17 and the front panel 11 and the baffle plate 16 is smooth, ensuring the appearance of the front panel 11. Furthermore, because the connection between the connecting plate 17 and the front panel 11 and the baffle plate 16 is smooth, oil stains adhering to the baffle plate 16 and the connecting plate 17 are easy to clean.

[0045] 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.
