Description

Technical Field

[0001] This utility model relates to the technical field of oil fume extraction equipment, specifically to a novel oil guiding component and an oil fume extractor. Background Technology

[0002] A range hood, also known as a kitchen exhaust hood, is a kitchen appliance that purifies the kitchen environment. It is typically installed above the stove and quickly removes harmful fumes and grease produced during cooking, venting them outdoors. It also condenses and collects these fumes, reducing pollution and purifying the air, and provides safety features such as protection against toxic substances and explosions.

[0003] Cooking fumes typically contain grease, and after being expelled outdoors by a range hood, grease usually remains on the hood. Range hoods generally have dual air inlets on the top side, each equipped with an air intake mesh. A glass baffle assembly further separates the hood from the main body, creating a long air inlet at the bottom that runs the same length as the hood. When the range hood is operating, cooking fumes enter the hood body simultaneously through the upper and lower air inlets of the baffle assembly. There, they are centrifugally separated and collected into grease by the duct system, then flow into the grease cup through a grease guide structure, thus achieving grease drainage.

[0004] However, in the relevant range hood technology, the grease separated by the air duct system can easily drip through the upper air inlet onto the stovetop, and the grease on the rectifier glass assembly cannot be effectively guided to the grease cup, which can easily cause stovetop contamination.

[0044] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0045] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this applies. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0047] The following is combined Figures 1 to 6The embodiments of this utility model will be described below. It should be understood that the following description is merely an illustrative embodiment of this utility model and does not constitute any limitation on this utility model.

[0048] Combination Figures 1 to 6 The range hood includes a duct system 1, a smoke collection box 2, and a baffle glass assembly 3. The smoke collection box 2 has a smoke collection chamber 21, an upper air inlet, and a lower air inlet. The baffle glass assembly 3 is located on the side of the smoke collection box 2. The smoke collection box 2 is located below the duct system 1. The duct system 1 can draw oil fumes into the smoke collection chamber 21 from the lower air inlet and exhaust them to the outside environment from the upper air inlet.

[0049] An embodiment of this utility model provides a novel oil guiding assembly, which includes an upper oil guiding plate assembly 100, an oil cup 200, and a lower oil guiding plate 300.

[0050] The upper oil guide plate assembly 100 is positioned above the smoke collection box 2 and is located between the air duct system 1 and the smoke collection box 2, so that the grease separated from the air duct system 1 can drip onto the upper oil guide plate assembly 100 and be guided into the smoke collection box 2.

[0051] The oil cup 200 is located at the lower end of the smoke collection box 2. Under the action of gravity, the oil cup 200 can collect the grease that flows out from the smoke collection box 2, preventing the grease from dripping onto the stove and causing pollution.

[0052] The lower oil guide plate 300 is located below the rectifier glass assembly 3, which can guide the grease collected in the rectifier glass assembly 3 to the oil cup 200.

[0053] It is understood that the novel oil guiding component provided in the embodiments of this utility model, by setting an upper oil guiding plate assembly 100 between the air duct system 1 and the smoke collection box 2 to receive the grease separated by the air duct system 1, can prevent the grease from dripping onto the stovetop through the upper air inlet of the smoke collection box 2; and by setting a lower oil guiding plate 300 below the rectifier glass assembly 3 to guide the grease collected by the rectifier glass assembly 3 to the oil cup 200, further preventing the grease collected by the rectifier glass assembly 3 from dripping onto the stovetop; the oil cup 200 is set at the lower end of the smoke collection box 2, and under the action of gravity, the oil cup 200 can collect the grease guided from the smoke collection box 2, so that the grease from the air duct system 1 and the rectifier glass assembly 3 can be effectively guided and converged into the oil cup 200, avoiding stovetop contamination.

[0054] Combination Figure 1 Furthermore, in order to guide the grease above and below the outside of the air duct system 1 to the oil guide groove 121 and prevent grease from dripping and contaminating the stove, in some embodiments of this utility model, the upper oil guide plate assembly 100 includes an upper oil guide plate 110 and a smoke collection box top plate 120.

[0055] The top plate 120 of the smoke collection box is inclinedly installed on the top of the smoke collection box 2. The top plate 120 of the smoke collection box is provided with an oil guide groove 121 that penetrates the smoke collection chamber 21. The top plate 120 of the smoke collection box can guide the grease above the outside of the air duct system 1 to the smoke collection chamber 21. For example, the end of the top plate 120 of the smoke collection box with the oil guide groove 121 is inclined along the bottom of the smoke collection box 2 and abuts against the side wall of the smoke collection box 2, so that the grease above the outside of the air duct system 1 drips onto the top plate 120 of the smoke collection box under the action of gravity. After being guided by the oil guide groove 121 and the side wall of the smoke collection box 2, it can finally flow into the oil cup 200.

[0056] The upper oil guide plate 110 is inclinedly connected to the top plate of the smoke collection box 2. The vertical projection of the lower part of the air duct system 1 is located on the upper oil guide plate 110, which can guide the grease in the lower part of the air duct system 1 to the oil guide groove 121. For example, the first end of the upper oil guide plate 110 is connected to the top of the smoke collection box 2, and the second end of the upper oil guide plate 110 is inclined towards the oil guide groove 121 of the top plate 120 of the smoke collection box. The top plate 120 of the smoke collection box is located below the upper oil guide plate 110 and is connected to the top and back of the smoke collection box 2 with screws. In the vertical direction, the height of the first end of the upper oil guide plate 110 is higher than that of the second end of the upper oil guide plate 110, so that the grease in the lower part of the air duct system 1 is guided to the oil guide groove 121 under the action of gravity.

[0057] Of course, combined Figure 3 In one specific embodiment of this utility model, the upper oil guide plate 110 includes an oil guide base plate 111.

[0058] An oil guide flange 112 is provided on the edge of the oil guide base plate 111. The oil guide flange 112 can be formed by rolling the edge of the oil guide base plate 111. An oil guide port 113 is provided on the oil guide flange 112. The oil guide port 113 faces the oil guide groove 121, which can make the grease falling into the oil guide base plate 111 fall into the oil guide groove 121 better, and prevent the grease from overflowing onto the upper oil guide plate 110 and causing pollution.

[0059] In addition, combined Figure 1 and Figure 2 In some embodiments of this utility model, the novel oil guiding assembly further includes an oil receiving component 400. The oil receiving component 400 is disposed below the air duct system 1. Under the action of gravity, the oil receiving component 400 can guide the grease collected below the air duct system 1 to the smoke collection chamber 21. That is, the first end of the oil receiving component 400 can be connected to the lower part of the air duct system 1, and the second end of the oil receiving component 400 can be inclined towards the side wall of the smoke collection chamber 2, so that most of the grease in the air duct system 1 can fall into the smoke collection chamber 21 through the oil receiving component 400, thereby preventing grease from accumulating on the upper oil guiding plate assembly 100 and causing overflow pollution.

[0060] In this embodiment, the oil receiving component 400 can be a volute oil receiving groove. The volute oil receiving groove and the air duct system 1 can be connected by rivets to form an integral whole, while the upper oil guide plate 110 is located at the bottom of the air duct system 1.

[0061] Combination Figure 1 In some embodiments of this utility model, the rectifier glass assembly 3 includes a rectifier back plate 31 and a glass plate 32. The rectifier back plate 31 is fixed to the outer wall of the smoke collection box 2, and the glass plate 32 is disposed on the rectifier back plate 31.

[0062] The lower oil guide plate 300 has its first end mounted on the back plate 31 of the baffle plate, and its second end extending into the cavity of the oil cup 200. That is, in the vertical direction, the first end of the lower oil guide plate 300 is higher than its second end. Under the influence of gravity, the grease collected in the baffle plate glass assembly 3 can be guided into the oil cup 200 through the lower oil guide plate 300, further preventing the baffle plate glass assembly 3 from dripping onto the stovetop.

[0063] In this embodiment, the lower oil guide plate 300 can be formed by extending the rectifier back plate 31, so that the lower oil guide plate 300 and the rectifier back plate 31 can be integrally formed, thereby simplifying the structure of the new oil guide assembly and saving manufacturing costs.

[0064] Combination Figure 1 , Figure 2 and Figure 6 Furthermore, in order to prevent grease from splashing out during the process of guiding grease from the lower oil guide plate 300 to the oil cup 200, in some embodiments of the present invention, the novel oil guiding assembly also includes an oil baffle plate 500. The second end of the oil baffle plate 500 extends into the cavity of the oil cup 200, and the first end of the oil baffle plate 500 is connected to the second end of the lower oil guide plate 300, so that the grease on the lower oil guide plate 300 can flow into the oil cup 200 after passing through the oil baffle plate 500.

[0065] Specifically, in combination Figure 4 and Figure 5 In some embodiments of this utility model, the lower oil guide plate 300 is provided with a first air inlet 310 and a second air inlet 320, so that a first baffle plate 330, a second baffle plate 340 and a third baffle plate 350 can be formed on the lower oil guide plate 300.

[0066] The second baffle 340 is located between the first air inlet 310 and the second air inlet 320, the first baffle 330 is located next to the first air inlet 310, and the second baffle 340 is located next to the second air inlet 320.

[0067] When the duct system 1 is working, cooking fumes can be drawn into the smoke collection chamber 21 of the smoke collection box 2 from the first air inlet 310 and the second air inlet 320, and then discharged from the upper air inlet and exhausted to the outside environment by the fan in the duct system 1. The first baffle 330, the second baffle 340, and the third baffle 350 can prevent more cooking fumes from entering the smoke collection chamber 21. In other words, by increasing the shielding area on both sides and in the middle of the lower oil guide plate 300, the negative pressure at the lower air inlet is effectively increased, enhancing the fume extraction effect, preventing fumes from escaping upwards, reducing the difficulty of smoke collection, preventing smoke escape, and improving the user experience.

[0068] In some embodiments of this invention, the widths of the first baffle plate 330 and the third baffle plate 350 are 80mm to 120mm, and the width of the second baffle plate 340 is 50mm to 100mm. For example, when the widths of the first baffle plate 330 and the third baffle plate 350 are both 100mm, the width of the second baffle plate 340 is 75mm; or, when the widths of the first baffle plate 330 and the third baffle plate 350 are both 95mm, the width of the second baffle plate 340 is 65mm. This allows the lower oil guide plate 300 to not only guide oil but also reduce the air intake area of ​​the lower air inlet, increasing the negative pressure effect. When applied to a range hood, this can increase the upward airflow of the range hood to 0.5 to 1m³. 3 / s, effectively enhances the smoking effect.

[0069] Combination Figure 4 and Figure 5 In order to prevent grease from dripping from the first air inlet 310 and the second air inlet 320 and contaminating the stove, in some embodiments of this utility model, the lower oil guide plate 300 and the oil baffle plate 500 are both inclinedly arranged in the smoke collection chamber 21 of the smoke collection box 2.

[0070] Moreover, the projections of the first air inlet 310 and the second air inlet 320 onto the oil baffle 500 are smaller than the area of ​​the oil baffle 500, so that even if grease drips from the first air inlet 310 and the second air inlet 320, it can fall onto the oil baffle 500.

[0071] Combination Figures 1 to 6 In an embodiment of this utility model, a range hood is also provided, which includes the novel oil guiding component, smoke collection box 2 and air duct system 1 described above.

[0072] The smoke collection box 2 has a smoke collection chamber 21. An upper air inlet is provided above the smoke collection box 2 to connect with the smoke collection chamber 21. The air duct system 1 is located above the upper air inlet and can draw the oil fumes in the smoke collection chamber 21 to the outside through the upper air inlet.

[0073] The new oil guiding component is installed in the smoke collection box 2.

[0074] It is understood that the range hood provided in the embodiments of this utility model, due to including the aforementioned novel oil guiding component, inevitably possesses all the advantages of that component. That is, the range hood can also effectively guide and collect grease from the duct system 1 and the rectifier glass assembly 3 into the oil cup 200, avoiding stovetop contamination.
