The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.
[0029] The terms “a,” “one,” “the,” and “” are used to indicate the existence of one or more elements / components / etc.; the terms “include” and “have” are used to indicate an open-ended meaning of inclusion and that there may be other elements / components / etc. in addition to the listed elements / components / etc.
[0030] See Figures 1 to 5 This utility model provides a range hood housing, including a smoke collection chamber assembly 1 and two oil guide plates 2. The smoke collection chamber assembly 1 forms a smoke collection chamber 11, and has a smoke inlet 111 and a smoke outlet 112 communicating with the smoke collection chamber 11. The smoke inlet 111 slopes downward from front to back, and the smoke outlet 112 is located at the top of the smoke collection chamber assembly 1. Under the action of the fan assembly 4, the fumes enter from the smoke inlet 111 and flow out from the smoke outlet 112, and are finally discharged through the pipe.
[0031] Two oil guide plates 2 are symmetrically arranged inside the smoke collection chamber 11, one on the first side and the other on the second side, opposite to each other. Each oil guide plate 2 includes a first plate 21, which is connected to the top surface and rear wall of the smoke collection chamber 11. The connection point between the first plate 21 and the top surface of the smoke collection chamber 11 is located at the edge of the smoke outlet 112. The first plates 21 of the two oil guide plates 2 are inclined from top to bottom in opposite directions and from front to back downwards. The two oil guide plates 2 and the smoke collection chamber assembly 1 together define the channel for absorbing oil fumes, allowing the oil fumes to enter from the smoke inlet 111, flow through the channel defined by the two oil guide plates 2 and the smoke collection chamber assembly 1, and exit from the smoke outlet 112 into the smoke collection chamber 11.
[0032] In this embodiment of the invention, the first plates 21 of the two oil guide plates 2 are inclined from top to bottom in directions opposite to each other. For example, the first plate 2 of the oil guide plate 2 on the first side is inclined from top to bottom in a direction opposite to the second side, and the first plate 2 of the oil guide plate 2 on the second side is inclined from top to bottom in a direction opposite to the first side. This creates a funnel-shaped space between the two oil guide plates 2, which can effectively guide the oil fumes into the adsorption area, significantly improving the smoke extraction efficiency. Furthermore, the oil fume gas enters the channel more smoothly, reducing airflow resistance and effectively guiding the oil fume gas into the fan section inside the air box assembly 3, where it can be quickly sucked away and promptly discharged to the common flue, further improving the efficiency of oil fume extraction and ensuring that the equipment operates efficiently while maintaining low noise.
[0033] The range hood in this embodiment of the utility model can be a side-suction range hood, and the smoke inlet 111 formed by the smoke collection chamber assembly 1 is inclined downward from front to back to form a side-suction range hood.
[0034] The smoke collection chamber assembly 1 may include a top plate, a rear plate, a bottom plate, a front plate, a left side plate, and a right side plate, which together form the smoke collection chamber 11. The top plate, rear plate, bottom plate, and front plate may be formed by bending a single plate. The vertical dimension of the front plate is smaller than that of the rear plate, causing the smoke inlet 111 to tilt forward, forming a side-suction smoke inlet 111.
[0035] In some embodiments, the first plate 21 is inclined downwards from front to back, forming a spatial shape that is higher in the front and lower in the back. The oil sludge condensed on the oil guide plate 2 can flow backwards along the first plate 21 and eventually be guided into the oil sludge collection device 12 located at the bottom. The forward and backward inclined design of the oil guide plate 2 allows the oil sludge condensed on the surface of the oil guide plate 2 to be guided into the oil sludge collection device 12 in a timely manner, which is convenient for cleaning.
[0036] In some embodiments, see Figure 4 and Figure 5 The first plate 21 includes an adjacent first side and a second side. The first side is located near the smoke outlet 112, and the second side is located near the rear wall of the smoke collection chamber 11. The first side is bent upward to form a first folded edge 211, which is connected to the edge of the smoke outlet 112. The first plates 21 of the two oil guide plates 2 can be connected to the two opposite edges of the smoke outlet 112, respectively. The first folded edge 211 can be basically vertically positioned.
[0037] The top surface of the smoke collection chamber 11 may be provided with a connecting frame, and the first folded edge 211 is connected to the connecting frame. The connecting frame may extend from front to back along the top surface of the smoke collection chamber 11. The inner surface of the top plate constitutes the top surface of the smoke collection chamber 11, and the first folded edge 211 may be directly connected to the top plate or connected to the connecting frame. In an exemplary embodiment, the connection method between the first folded edge 211 and the connecting frame may be one or more of welding, riveting, and screw connection.
[0038] In some embodiments, see Figure 2 , Figure 4 and Figure 5 The second side of the first plate 21 is bent downwards to form a second folded edge 212, which is connected to the rear wall of the smoke collection chamber 11. The first plate 21 is connected to both the top and rear wall of the smoke collection chamber 11, allowing for a stable connection between the oil guide plate 2 and the smoke collection chamber assembly 1. The inner surface of the rear plate forms the rear wall of the smoke collection chamber 11. The first plate 21 is connected to the rear wall via the second folded edge 212, allowing for flexible use of various connection methods. In an exemplary embodiment, the second folded edge 212 and the rear wall can be connected by welding, riveting, or screws, or by one or more of these methods.
[0039] In some embodiments, see Figure 2 , Figure 4 and Figure 5 The oil guide plate 2 also includes a second plate 22, which is connected to the side of the first plate 21 away from the smoke outlet 112. The second plate 22 is inclined downwards from front to back and gradually inclines upwards in the direction away from the first plate 21. The downward inclining design of the second plate 22 creates a space that is higher in the front and lower in the back, allowing the oil condensed on the oil guide plate 2 to flow backwards along the second plate 22 and eventually be guided into the oil collection device 12 located at the bottom. The forward and backward inclining design of the oil guide plate 2 allows the oil condensed on its surface to be promptly guided into the oil collection device 12 for easy cleaning.
[0040] In some embodiments, the surface of the oil guide plate 2 is coated with an anti-adhesion material, which can effectively reduce the probability of oil stains adhering, improve the oil guiding effect, and facilitate cleaning.
[0041] In some embodiments, see Figure 2 , Figure 4 and Figure 5 The first plate 21 is triangular or trapezoidal, and its cross-sectional area gradually increases from front to back. The side connecting the first plate 21 and the second plate 22 is inclined downwards from front to back. The triangular or trapezoidal shape of the first plate 21 allows the side connecting it to the second plate 22 to be inclined, enabling oil sludge accumulated on the first plate 21 to flow from front to back and ultimately be guided into the oil collection device 12. Furthermore, the triangular or trapezoidal shape of the first plate 21 facilitates the forward and backward inclination of the second plate 22.
[0042] In some embodiments, see Figure 2 , Figure 4 and Figure 5The second plate 22 is triangular or trapezoidal. In the exemplary embodiment, the cross-sectional area of the second plate 22 gradually decreases from front to back. The triangular or trapezoidal shape of the second plate 22 can complement the shape of the first plate 21, so that the two oil guide plates 2 can be substantially parallel on the side near the smoke inlet 111.
[0043] In some embodiments, see Figure 4 and Figure 5 The oil guide plate 2 also includes a third plate 23, which is connected to the side of the second plate 22 away from the first plate 21. The third plates 23 of the two oil guide plates 2 are inclined from top to bottom in opposite directions. By tilting the third plates 23 to both sides, the flared shape can be further expanded, increasing the area of the smoke inlet 111. This allows the oil fumes to enter the channel more smoothly, reduces airflow resistance, and effectively guides the oil fumes into the fan section inside the air box assembly 3, where they can be quickly sucked away and promptly discharged to the common flue, further improving the efficiency of oil fume extraction and ensuring that the equipment maintains low noise while operating efficiently.
[0044] In some embodiments, see Figure 4 and Figure 5 The oil guide plate 2 also includes a fourth plate 24, which is connected to the side of the third plate 23 away from the second plate 22. The fourth plate 24 is connected to the bottom surface and the front wall surface of the smoke collection chamber 11. The fourth plate 24 extends to the smoke inlet 111 and is connected to the bottom surface and the front wall surface. The inner surface of the front plate forms the front wall surface of the smoke collection chamber 11, and the inner surface of the bottom plate forms the bottom surface of the smoke collection chamber 11.
[0045] In some embodiments, see Figure 4 and Figure 5 The fourth plate 24 is bent upward on the side near the smoke inlet 111 to form a third fold 241, which is flush with the smoke inlet 111. The third fold 241 is formed by bending on the fourth plate 24 to facilitate the connection of the fourth plate 24 with other components.
[0046] In some embodiments, see Figures 1 to 3 The housing of this embodiment also includes an oil collection device 12, which is located at the bottom of the smoke collection chamber assembly 1. The oil guide plate 2 can guide oil to the oil collection device 12, facilitating oil treatment and reducing the long-term deposition of oil in the range hood.
[0047] In some embodiments, see Figures 1 to 3The housing of this utility model embodiment also includes a bellows assembly 3, which is located at the top of the smoke collection chamber assembly 1 and connected to the edge of the smoke outlet 112. A fan assembly 4 can be installed inside the bellows assembly 3. The fan assembly 4 can create a negative pressure, thereby drawing the oil fumes from the smoke inlet 111 into the smoke collection chamber 11, and then into the bellows assembly 3 through the smoke outlet 112, and finally discharging them through the pipe.
[0048] In some embodiments, see Figure 1 The housing of this utility model embodiment also includes a smoke collection hood 13, which is disposed at the smoke inlet 111. Multiple smoke inlets can be provided on the smoke collection hood 13. In an exemplary embodiment, a main smoke inlet 131 can be provided on the smoke collection hood 13, and a left smoke inlet 132 and a right smoke inlet 133 can be respectively provided on both sides of the main smoke inlet 131.
[0049] In some embodiments, see Figure 1 The housing of this utility model embodiment also includes an oil mesh 14, which is disposed on the smoke collection hood 13. In an exemplary embodiment, the oil mesh 14 may be disposed at the main smoke inlet 131 of the smoke collection hood 13.
[0050] In some embodiments, see Figure 1 and Figure 3 The housing of this utility model embodiment also includes a smoke baffle assembly. In specific implementations, the smoke baffle assembly may include an upper smoke baffle 15 and a lower smoke baffle 16.
