Description

Technical Field

[0001] This utility model relates to the field of smoke hood technology, specifically to a smoke hood. Background Technology

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. Installed above the stove, it quickly removes cooking fumes and harmful oil fumes from the stove and vents them outdoors. When the range hood's fan starts, the cooking fumes are drawn into the inner air chamber through the air inlet. After entering the inner air chamber, some of the airflow first flows towards the bottom plate and then rises. In current technology, the bottom plate of the inner air chamber is relatively close to the air inlet, causing the airflow to hit the bottom plate at a high velocity, resulting in significant noise.

[0014] Compared with the prior art, the smoke hood of this utility model has the following advantages:

[0015] This utility model of a range hood divides the inner air box into an upper box and a lower box. By reasonably setting the depth of the lower box, the distance between the bottom plate of the lower box and the air inlet can be increased. This increases the flow distance of the airflow before it hits the bottom plate of the lower box, causing the airflow velocity to decrease during this process. This results in the airflow hitting the bottom plate of the lower box at a lower velocity, thereby reducing the generated noise. Furthermore, because the bottom plate of the lower box is farther from the air inlet, noise generated at the bottom plate of the lower box is also attenuated more during its transmission to the air inlet, further reducing the noise transmitted from the air inlet. In addition, when manufacturing the inner air box, the bottom plate of the original, shallower air box structure can be removed to form the upper box, and the newly added lower box can be connected to the upper box. Therefore, when manufacturing the new version of the inner air box, there is no need to re-mold, thus reducing manufacturing costs. Attached Figure Description

[0023] 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:

[0024] This utility model discloses a smoke hood. Please refer to [link / reference]. Figures 1 to 2The smoke hood proposed in this utility model includes a housing 1, an inner air box 2, and an outer air box 3. The housing 1 has an air intake panel 11 and an installation cavity 12 located behind the air intake panel 11. The air intake panel 11 is provided with an air intake port 111. The inner air box 2 is installed in the installation cavity 12 of the housing 1. The inner air box 2 includes an upper box 21 and a lower box 22. The lower box 22 is connected to the lower part of the upper box 21 and communicates with the interior of the upper box 21. The upper box 21 is provided with an air collection port 211. The air intake port 111 communicates with the interior of the upper box 21 through the air collection port 211. The outer air box 3 is connected to the inner air box 2 and is located above the housing 1. The outer air box 3 is provided with an exhaust fan 4 and an exhaust port.

[0025] In this embodiment, the housing 1 and the outer air box 3 form the overall appearance structure of the range hood. The inner air box 2 forms the inner lining structure of the housing 1 within the mounting cavity 12. The portion of the suction panel 11 with suction ports 111 is connected to the upper housing 21, so that the suction ports 111 and the air collection ports 211 are correspondingly connected. The suction ports 111 are connected to the interior of the upper housing 21 through the air collection ports 211, and the outer air box 3 is also connected to the interior of the upper housing 21. When the exhaust fan 4 is running, the negative pressure generated by the exhaust fan 4 within the inner air box 2 causes external airflow to enter the inner air box 2 through the suction ports 111, thus allowing the range hood to normally extract fumes. After entering the inner air box 2, the airflow flows to the outer air box 3 and then exits from the exhaust port.

[0026] After the airflow enters the inner air box 2, part of it will first flow to the bottom plate of the inner air box 2 and then flow upward. The inner air box 2 is divided into an upper box 21 and a lower box 22. By reasonably setting the depth of the lower box 22, the distance between the bottom plate of the lower box 22 and the air intake 111 can be increased. In this way, the flow distance of the airflow before it hits the bottom plate of the lower box 22 can be increased, so that the airflow velocity will be reduced in this process, and the airflow will hit the bottom plate of the lower box 22 at a lower velocity, thereby reducing the noise generated. Furthermore, since the distance between the bottom plate of the lower box 22 and the air intake 111 is greater, the noise generated at the bottom plate of the lower box 22 can also be attenuated more in the process of being transmitted to the air intake 111, thereby further reducing the noise transmitted from the air intake 111.

[0027] The smoke hood of this utility model, such as Figure 1 and Figure 2 As shown, an opening is provided on the bottom plate of the upper box 21, and the lower box 22 communicates with the upper box 21 through the opening. The size of the opening is smaller than the size of the bottom plate of the upper box 21. When processing the inner air box 2, the bottom plate of the original air box structure with a smaller depth can be removed to serve as the upper box 21, and the newly added lower box 22 can be connected to the opening of the upper box 21. Therefore, when processing the new version of the inner air box 2, it is not necessary to re-make the mold, thereby reducing processing costs.

[0028] The smoke hood of this utility model, such as Figure 1 and Figure 2 As shown, the rear panel of the lower box 22 is connected to the rear panel of the upper box 21, the left and right side panels of the lower box 22 are connected to the left and right side panels of the upper box 21, the upper edge of the front panel of the lower box 22 is folded forward to form a connecting part 221, the connecting part 221 is connected to the bottom plate of the upper box 21, and the connecting part 221 is connected to the bottom of the bottom plate of the upper box 21.

[0029] The rear panel and left and right side panels of the lower housing 22 are connected to the rear panel and left and right side panels of the upper housing 21, respectively, so that the upper housing 21 and the lower housing 22 can be combined to form a complete bellows structure. This also increases the connection points between the upper housing 21 and the lower housing 22, improving the connection strength. The lower housing 22 is connected to the bottom plate of the upper housing 21 through the connecting part 221, which increases the connection area between the front panel of the lower housing 22 and the upper housing 21, thereby improving the connection stability. Furthermore, the lower housing 22 can support the upper housing 21 through the connecting part 221, making the overall structure of the inner bellows 2 more stable.

[0030] The smoke hood of this utility model, such as Figure 1 and Figure 2 As shown, the bottom plate of the lower housing 22 is provided with an oil outlet 222, which communicates with the mounting cavity 12 of the housing 1. Oil accumulated inside the upper housing 21 and lower housing 22, as well as oil dripping from the exhaust fan 4 into the inner air cavity, will flow under gravity to the bottom plate of the lower housing 22, and then flow from the oil outlet 222 to the mounting cavity 12 located below the lower housing 22. This prevents oil from accumulating on the walls inside the lower housing 22. Multiple oil outlets 222 can be provided, spaced apart along the length of the bottom plate of the lower housing 22, so that the oil flowing to the bottom plate of the lower housing 22 can flow more quickly and fully to the mounting cavity 12 below.

[0031] The smoke hood of this utility model, such as Figure 1 and Figure 2 As shown, the bottom of the mounting cavity 12 is provided with an oil drip hole 121, and also includes an oil cup 5. The oil cup 5 is installed below the housing 1, and the opening of the receiving cavity of the oil cup 5 faces the oil drip hole 121. The oil flowing from the oil outlet 222 to the mounting cavity 12 can further flow through the oil drip hole 121 to the oil cup 5, so as to realize the collection of oil by the oil cup 5. The length of the oil cup 5 is the same as the length of the housing 1 to increase the capacity of the oil cup 5. There are multiple oil drip holes 121, which are spaced apart along the length direction of the housing 1, so that the oil flowing into the mounting cavity 12 can flow into the oil cup 5 more quickly and fully.

[0032] The smoke hood of this utility model, such as Figure 1 and Figure 2As shown, the suction panel 11 has a panel reinforcement plate 6 on the side facing the inner air box 2. The panel reinforcement plate 6 has a first connecting plate 61 and a second connecting plate 62. The first connecting plate 61 is connected to the front plate of the upper box 21, and the second connecting plate 62 is connected to the bottom plate of the upper box 21.

[0033] The panel reinforcement plate 6 can improve the overall structural strength of the suction panel 11 and prevent the suction panel 11 from being easily deformed or damaged. The first connecting plate 61 and the second connecting plate 62 can realize the effective connection between the panel reinforcement plate 6 and the upper box 21, so that the panel reinforcement plate 6 can directly share part of the weight of the upper box 21, thereby enabling the panel reinforcement plate 6 to more effectively play its reinforcing and supporting role.

[0034] The smoke hood of this utility model, such as Figure 1 and Figure 2 As shown, the front panel of the upper housing 21 abuts against the suction panel 11. The front panel of the upper housing 21 has a connecting position 212 on the side facing the suction panel 11. The connecting position 212 forms a groove on the front panel of the upper housing 21. The first connecting plate 61 extends into the groove and connects with the upper surface.

[0035] The first connecting plate 61 extends rearward, and the groove can accommodate and accommodate the first connecting plate 61. The upper surface of the first connecting plate 61 is connected to the downward groove wall of the groove, so that the first connecting plate 61 can provide upward support for the upper box 21.

[0036] The smoke hood of this utility model, such as Figure 1 and Figure 2 As shown, the second connecting plate 62 is parallel to the bottom plate of the upper box 21 and supports the upper box 21 upwards. The second connecting plate 62 extends backwards and is located below the upper box 21. The upper surface of the second connecting plate 62 is connected to the lower surface of the bottom plate of the upper box 21, so that the second connecting plate 62 can provide upward support for the upper box 21.

[0037] The smoke hood of this utility model, such as Figure 1 and Figure 2 As shown, the panel reinforcement plate 6 has a clearance opening that surrounds the air intake 111. The first connecting plate 61 is located above the clearance opening, and the second connecting plate 62 is located below it. The clearance opening avoids the air intake 111 and the air collection port 211, allowing for effective communication between them. The first connecting plate 61 and the second connecting plate 62 are located on the upper and lower sides of the clearance opening, respectively, resulting in a more rational distribution of their positions.

[0038] The smoke hood of this utility model, such as Figure 1 and Figure 2As shown, a connector 7 is connected to the back plate of the housing 1. The connector 7 has at least a first connecting surface parallel to the back plate of the housing 1 and a second connecting surface parallel to the bottom plate of the lower box 22. The first connecting surface is connected to the back plate of the housing 1, and the second connecting surface is formed by folding down the upper edge of the first connecting surface. The second connecting surface is connected to the bottom plate of the lower box 22 and supports the lower box 22 upward.

[0039] The connector 7 is connected to the back plate of the housing 1 and the bottom plate of the lower housing 22 via a first connecting surface and a second connecting surface, respectively, to achieve an indirect connection between the lower housing 22 and the back plate of the housing 1, making the internal structure of the range hood more compact and stable. The upper edge of the first connecting surface is folded forward and downward to form a second connecting surface. The second connecting surface can not only be connected to the bottom plate of the lower housing 22, but also provide upward support for the lower housing 22, thereby improving the installation stability of the lower housing 22 in the mounting cavity 12.

[0040] 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.
