Description

Technical Field

[0001] The utility model relates to the technical field of oil fume purification equipment, in particular to a range hood. Background Art

[0002] The range hood is a device used to absorb and exhaust the oil smoke generated during the cooking process. The oil smoke is sucked in from the air inlet and begins to condense when it comes into contact with the inner cavity of the range hood, forming oil stains that are difficult to clean in the inner cavity. When the oil stains are not cleaned for a long time, a solidified layer will form, which increases the difficulty of cleaning the cavity. At the same time, the rotation of the impeller collides with the oil smoke particles and the centrifugal separation of the oil smoke particles causes oil stains to adhere to the surface of the blades and the volute. Over time, the impeller will become heavier, the blade path will become narrower, and there will be problems with the dynamic balance of the impeller. The roughness of the inner wall of the volute will increase, and the resistance of the air duct will increase, which will reduce the suction and exhaust performance of the range hood and increase the noise. Adding an oil net at the front end of the air inlet of the range hood can improve grease separation and reduce oil pollution in the internal cavity of the range hood to a certain extent.

[0003] In the prior art, a side-suction range hood with two air inlets has an oil net disposed at the upper air inlet to separate grease from the oil fume, but the grease separation effect is poor, and it is inconvenient to clean, which easily leads to a reduction in the service life of the range hood.

DETAILED DESCRIPTION

[0029] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] Reference Figures 1 to 5 As shown, the utility model proposes a range hood, comprising a fan assembly 2 and a smoke collecting chamber 1, the fan assembly 2 is located above the smoke collecting chamber 1 and is connected to the smoke collecting chamber 1, the front side plate 11 of the smoke collecting chamber 1 is provided with a first air inlet 111 and a second air inlet 112 from top to bottom, and the first air inlet 111 and the second air inlet 112 are arranged at intervals; an oil net assembly 13 is provided in the smoke collecting chamber 1, one end of the oil net assembly 13 is located above the first air inlet 111 and connected to the front side plate 11, the other end of the oil net assembly 13 is located below the first air inlet 111 and connected to the back plate 12 of the smoke collecting chamber 1, the oil net assembly 13 is inclined from bottom to top toward one side of the front side plate 11, so that the oil smoke flowing through the first air inlet 111 and the second air inlet 112 must pass through the oil net assembly 13 to enter the fan assembly 2.

[0034] Specifically, by opening a first air inlet 111 and a second air inlet 112 on the front side panel 11, the air intake volume is increased, one end of the oil net assembly 13 is located above the first air inlet 111 and connected to the front side panel 11, and the other end of the oil net assembly 13 is located below the first air inlet 111 and connected to the back panel 12 of the smoke collecting chamber 1, and the oil net assembly 13 is inclined from bottom to top toward one side of the front side panel 11, so that the oil smoke flowing through the first air inlet 111 and the second air inlet 112 must pass through the oil net assembly 13 to enter the fan assembly 2, and the oil net assembly 13 can not only separate and filter the oil smoke of the first air inlet 111 and the second air inlet 112 at the same time, but also can filter the oil smoke separately when any one of the air inlets is used. Compared with separately setting up oil nets at respective air inlets, the present solution sets the oil net assembly at an angle, which can not only filter the oil smoke at the two air inlets but also makes the setting and installation more convenient. At the same time, the inclined setting of the oil net assembly 13 can also increase the contact area of ​​the oil smoke, so that the oil smoke can be fully separated and filtered by the oil net assembly 13, thereby improving the grease separation effect.

[0035] Reference Figures 6 to 8As shown, in some embodiments of the utility model, the oil net assembly 13 includes a mounting bracket 131 and a separation oil net 132, the upper end of the mounting bracket 131 is fixedly connected to the front side plate 11, the lower end of the mounting bracket 131 is fixedly connected to the back plate 12, the separation oil net 132 is detachably arranged on the mounting bracket 131, and a first oil leakage hole 1311 is opened on the lower end plate 1312 of the mounting bracket 131.

[0036] Specifically, the mounting bracket 131 provides mounting support for the separation oil net 132, and the separation oil net 132 is detachably mounted on the mounting bracket 131 for easy disassembly and cleaning. In addition, a first oil leakage hole 1311 is provided on the lower end plate 1312 of the mounting bracket 131, so that the grease separated and filtered by the separation oil net 132 is discharged from the first oil leakage hole 1311, thereby preventing grease from accumulating on the separation oil net 132 and the mounting bracket 131, thereby affecting the separation effect. In addition, when too much grease accumulates on the mounting bracket 131, it will drip onto the condensation plate 14 through the gaps in the separation oil net 132, thereby affecting the user experience.

[0037] Reference Figure 7 and Fig. 9 As shown, in some embodiments of the utility model, a first oil guide plate 133 is provided at the lower end of the mounting bracket 131, the upper end of the first oil guide plate 133 is fixedly connected to the front side of the lower end plate 1312 of the mounting bracket 131, the lower end of the first oil guide plate 133 abuts against the back plate 12, the first oil guide plate 133 is inclined from top to bottom toward one side of the back plate 12, and a plurality of second oil leakage holes 1331 are opened on the first oil guide plate 133, and a first spacing H1 is provided between the front end hole wall of the second oil leakage hole 1331 and the back plate 12.

[0038] Specifically, a first oil guide plate 133 is arranged at the lower end of the mounting bracket 131, the upper end of the first oil guide plate 133 is fixedly connected to the front side of the lower end plate 1312 of the mounting bracket 131, the lower end of the first oil guide plate 133 is in contact with the back plate 12, and the first oil guide plate 133 is tilted from top to bottom toward one side of the back plate 12, and the grease separated and filtered by the separation oil net 132 flows downward from the first oil leakage hole 1311, and under the guidance of the first oil guide plate 133, flows to the second oil leakage hole 1331, and the first oil guide plate 133 is tilted backward from top to bottom, which accelerates the flow of grease and allows the grease to flow smoothly into the second oil leakage hole 1331, avoiding oil drops from falling on the condensation plate. In addition, the first oil guide plate 133 can support the mounting bracket 131, so that the connection between the mounting bracket 131 and the back plate 12 is more firm and stable. The second oil leakage hole 1331 is provided on the first oil guide plate 133. The shapes of the first oil leakage hole 1311 and the second oil leakage hole 1331 can be round holes or long holes, which are not specifically limited here, as long as the oil droplets can drip smoothly.

[0039] Reference Figure 8 As shown, in some embodiments of the present invention, the oil separation net 132 includes a first net body and a second net body that are interlocked and connected, the first net body is provided with a plurality of first condensation pieces, the second net body is provided with a plurality of second condensation pieces, and the plurality of first condensation pieces and the plurality of second condensation pieces are arranged in an interlaced and interlocked manner.

[0040] Specifically, the oil separation net 132 is a double-layer net structure, including a first net body and a second net body that are interlocked and connected to each other. A plurality of first condensation pieces are provided on the first net body, and a plurality of second condensation pieces are provided on the second net body. The first condensation pieces and the second condensation pieces are interlocked so that the oil droplets condensed in the second condensation pieces fall into the first condensation pieces to prevent the oil droplets from penetrating. At the same time, the first net body and the second net body are interlocked to improve the separation effect.

[0041] In the example, the first net body and the second net body are both cast aluminum parts with a large weight. During the installation process, the second net body is first installed on the mounting bracket 131, and then the first net body is installed on the mounting bracket 131. The first net body, the second net body and the mounting bracket are fixedly connected by means of a bayonet buckle. For easy taking, a handle is provided on the front side of the first net body.

[0042] Reference Figure 5 As shown, in some embodiments of the present invention, the oil net assembly 13 is formed with a bend away from the front side plate 11 and is designed at an obtuse angle. One end of the oil net assembly 13 is located above the first air inlet 111 and connected to the front side plate 11, and the other end of the oil net assembly 13 is located below the first air inlet 111 and connected to the back plate 12 of the smoke collecting chamber 1.

[0043] Specifically, the oil net assembly 13 is provided with a bending structure, so as to increase the area of ​​the oil net assembly 13, thereby increasing the contact area between the oil smoke and the oil net assembly 13, reducing resistance, and improving the grease separation efficiency.

[0044] It is understandable that the obtuse angle of the oil net assembly 13 is conducive to the upward flow of the smoke oil, while avoiding the occurrence of cleaning dead corners that affect the cleaning efficiency. The obtuse angle of the oil net assembly 13 can guide the grease, allowing the grease to slide smoothly along the direction of the oil net assembly 13 into the oil cup 16, and preventing the grease from dripping directly onto the condensation plate 14 through the gap of the oil net assembly 13, affecting the user experience.

[0045] In some embodiments of the present invention, the upper end of the bent portion abuts against the front side plate 11 , and the bent portion is disposed below the first air inlet 111 .

[0046] Specifically, the upper end of the bend is in contact with the front side plate 11, and the bend is arranged below the first air inlet 111. While ensuring that both air inlets can filter the oil fumes, the separation oil net 132 above the bend is moved forward to be close to the first air inlet 111, thereby increasing the resistance of the first air inlet 111 and thus increasing the oil fume flux of the second air inlet 112.

[0047] Reference Figure 2 , Figure 4 and Figure 6 As shown, in some embodiments of the utility model, the range hood also includes a condensation bracket 15 and a condensation plate 14 both arranged in the lower wind chamber, the condensation bracket 15 includes a horizontal section 151 and an inclined section 152, the rear end of the horizontal section 151 is fixedly connected to the bottom of the back plate 12, the lower end of the inclined end is connected to the front end of the horizontal section 151 and is designed at an acute angle, the inclined section 152 is inclined from bottom to top toward one side of the back plate 12, the condensation plate 14 is inclined from bottom to top toward one side of the back plate 12 and is arranged on the inclined section 152, and the second air inlet 112 is arranged opposite to the condensation plate 14.

[0048] Specifically, the condensation bracket 15 provides installation support for the condensation plate 14. The condensation plate 14 is inclined from bottom to top toward the side of the back plate 12 along the inclined section 152, thereby forming an upward and backward guiding slope. The condensation plate 14 is opposite to the second air inlet 112. The condensation plate 14 guides the oil smoke flowing through the second air inlet 112 so that the oil smoke flows upward and is separated through the oil smoke component.

[0049] In some embodiments of the present invention, a second oil guide plate 153 connected to the back plate 12 is disposed at the upper end of the inclined section 152, the front end of the second oil guide plate 153 is fixedly connected to the inclined section 152, the second oil guide plate 153 is inclined from top to bottom toward one side of the back plate 12 and abuts against the back plate 12 at its rear side, and a third oil leakage hole 1531 is opened on the second oil guide plate 153. Figure 6 As shown, the oil mesh assembly 13 separates the oil smoke and the oil droplets generated flow through the first oil leakage hole 1311, the second oil leakage hole 1331 and the third oil leakage hole 1531 in sequence.

[0050] Reference Figure 3 and Fig. 9 As shown, in some embodiments of the present invention, along the vertical direction, the projection of the second oil leakage hole 1331 is located inside the third oil leakage hole 1531, and there is a second spacing H2 between the front hole wall of the third oil leakage hole 1531 and the back plate 12, the second spacing H2 is greater than the first spacing H1, and H2 ≥ H1 + 6. Therefore, when the oil droplets drip downward from the second oil leakage hole 1331, they can directly drip into the third oil leakage hole 1531, avoiding the oil droplets from dripping onto the condensation plate 14 and affecting the appearance.

[0051] Reference Figure 2, Figure 4 and Figure 5 As shown, in some embodiments of the utility model, the range hood also includes an oil cup 16 arranged at the bottom of the smoke collecting chamber 1, the oil cup 16 is detachably connected to the back plate 12, the oil cup 16 is provided with an oil collecting chamber, and a plurality of fourth oil leakage holes 1511 are opened on the horizontal section 151, and the oil collecting chamber is connected to the fourth oil leakage holes 1511.

[0052] Specifically, a plurality of fourth oil leakage holes 1511 are opened on the horizontal section 151, the oil cup 16 is arranged at the bottom of the smoke collecting chamber 1 and is located below the horizontal section 151, the oil cup 16 has an oil collecting chamber, and the fourth oil leakage holes 1511 are connected to the oil collecting chamber, so that oil droplets drip from the fourth oil leakage holes 1511 into the oil cup 16.

[0053] It should be noted that there are multiple first oil leakage holes 1311 , second oil leakage holes 1331 , third oil leakage holes 1531 and fourth oil leakage holes 1511 , and the specific numbers are not intended to be a limitation of the present invention.

[0054] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
