Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen appliances, and specifically to a range hood with a built-in oil guiding device. Background Technology
[0002] A range hood, also known as a cooking hood, is a kitchen appliance used to purify the kitchen environment. Installed above the stove, it quickly removes waste from combustion and harmful fumes produced during cooking, expelling them outdoors. It also condenses and collects these fumes, reducing pollution, purifying the air, and providing safety features such as protection against toxic substances and explosions.
[0003] A range hood typically includes a smoke extraction chamber and a fan box. When the smoke extraction chamber has an inclined structure, its oil cup is located at the bottom of the smoke extraction chamber. The filter screen and the oil accumulated on the filter screen are guided into the oil cup by the smoke guide plate.
[0004] However, the nature of the filter screen dictates that it must have gaps, which may allow oil stains to fall into the stove below through the gaps in the filter screen. Using a double-layer filter screen cannot eliminate the above possibility and will affect the smoke extraction efficiency of the range hood.
[0005] Therefore, the inventors conducted further research and developed a range hood with a built-in oil guiding device, which led to this invention. Utility Model Content
[0006] The purpose of this utility model is to provide a range hood with a built-in oil guiding device, which can prevent oil stains from dripping and is easy to clean and install.
[0007] To achieve the above objectives, the technical solution of this utility model is as follows:
[0008] A range hood with a built-in oil guiding device, including
[0009] The smoking chamber has an inclined bottom, with a filter screen on the upper half of the bottom surface and a smoke guide plate on the lower half surface. An oil cup is located on the lower edge of the smoke guide plate.
[0010] An oil guide plate is installed at the connection between the smoke chamber and the air box and is located in the smoke chamber. The oil guide plate is inclined and the inclination direction is the same as that of the smoke guide plate, and the lowest point of the oil guide plate is located above the smoke guide plate.
[0011] An oil guide plate is installed inside the smoking chamber so that the oil produced in the bellows falls onto the oil guide plate and then into the smoking chamber on the back of the smoke guide plate, and finally into the oil cup.
[0012] Furthermore, the oil guide plate is provided with a first folded edge, a second folded edge, and a third folded edge around its perimeter. The first folded edge and the third folded edge are L-shaped structures and are connected to the top plate of the smoking chamber. The second folded edge is located on both sides of the oil guide plate and is not connected to the top plate of the smoking chamber.
[0013] The first and third folds mainly serve a connecting function, while the second fold is used to guide the oil stains.
[0014] Furthermore, the first and third folds are L-shaped structures, with mounting holes provided on the side that contacts the top plate of the smoking chamber, and the height of the third fold is greater than that of the first fold.
[0015] Furthermore, a gap is left between the second and third folds, and an oil leakage hole is provided in this gap.
[0016] Furthermore, a flap glass is installed below the filter screen, and the flap glass is pivotally connected to the smoking chamber.
[0017] When the range hood is not in use, the flip-up glass is used to close the smoke inlet where the filter is located.
[0018] Furthermore, the connection angle between the oil guide plate and the third fold is 70-80°.
[0019] By adopting the above solution, this utility model has the following advantages compared with the prior art:
[0020] The oil guide plate is made of sheet metal and can be independently processed and installed without welding; the large angle design of the oil guide plate avoids oil leakage. Attached Figure Description

[0027] Oil guide plate 1, first fold 11, second fold 12, third fold 13, oil drain hole 14.
[0028] 2. Smoking chamber; 3. Filter screen; 4. Smoke guide plate; 5. Oil cup; 6. Flip glass; 7. Air box. Detailed Implementation
[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0030] like Figure 1 As shown, a range hood with a built-in oil guiding device includes a blower box 7 and a smoke extraction chamber 2. The blower box 7 is located above the smoke extraction chamber 2. The bottom of the smoke extraction chamber 2 is inclined. A smoke extraction port is opened on the upper half surface of the bottom, and a filter screen 3 is provided at the smoke extraction port. A smoke guide plate 4 is provided on the lower half surface, and an oil cup 5 is provided on the lower edge of the smoke guide plate 4.
[0031] like Figure 2 As shown, an oil guide plate 1 is provided above the filter screen 3 and at the connection between the smoke chamber 2 and the air box 7. The oil guide plate 1 has the same tilt angle as the filter screen 3 and the smoke guide plate 4. In this embodiment, its tilt angle is 78°. Figure 5 ).
[0032] refer to Figure 4 As shown, the oil guide plate 1 has a first folded edge 11, a second folded edge 12, and a third folded edge 13 around its perimeter. The first folded edge 11 and the third folded edge 13 are L-shaped and are bolted to the top plate of the smoking chamber 2. The heights of the first folded edge 11 and the second folded edge 12 are not the same, thus creating an angled inclination of the oil guide plate 1. The second folded edge 12 is located on both sides of the oil guide plate 1 and is not connected to the top plate of the smoking chamber 2. That is, the first folded edge 11 and the third folded edge 13 serve as the mounting edges of the oil guide plate 1, while the second folded edge 12 prevents oil dripping onto the oil guide plate 1 from flowing out to both sides. A gap is left between the second folded edge 12 and the third folded edge 13, so that the second folded edge 12 is slightly recessed relative to the oil guide plate 1, and an oil leakage hole 14 is provided at this gap. This allows the oil on the oil guide plate 1 to be guided to the smoking chamber 2 without a smoking port, and finally introduced into the oil cup 5.
[0033] Preferably, a hinged glass panel 6 is provided on the outside of the filter screen 3. The hinged glass panel 6 is closed when the range hood is not in operation. Figure 3 As shown.
[0034] The above are merely specific embodiments of this utility model. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in this utility model are for reference only and are not absolute limitations. Any non-substantial modifications made to this utility model shall be considered as infringing upon the protection scope of this utility model.
