[0002] A range hood, also known as a range hood, is a kitchen appliance that purifies the kitchen environment. It is installed above the kitchen stove and can quickly remove the waste from stove combustion and the oil smoke that is harmful to the human body produced during cooking and discharge it outdoors. At the same time, it condenses and collects the oil smoke, reduces pollution, purifies the air, and has a safety guarantee function of anti-toxicity and explosion-proof.

[0003] At present, the oil suction rack of existing range hoods is generally an outward convex fan-shaped structure, and the oil smoke will be condensed on the oil suction rack to form oil that flows into the oil cup; however, due to the complex structure of the oil suction rack, during the process of disassembling and cleaning (the disassembly process is also difficult, and there are more screw installation positions), there are many gaps and hidden surfaces on the inside, which makes cleaning difficult (need to use a rag to wipe it bit by bit), takes a long time, and reduces the use effect of the range hood; for this reason, we propose a double-cavity concave range hood.

After the oil smoke contacts the cold plate 6, it can be condensed to form oil liquid; the mounting plate 5 is fixedly installed inside the smoke hood 2, and the mounting plate 5 is provided with a plug-in hole 7 and a butt surface 8, and the cold plate 6 is provided with a protrusion 9 and a convex ridge 10, the protrusion 9 is plugged into the plug-in hole 7, and the convex ridge 10 is abutted against the top surface of the butt surface 8; in this embodiment, when the mounting plate 5 and the cold plate 6 are plugged in, the protrusion 9 is plugged into the plug-in hole 7, and the convex ridge 10 is on the top surface of the butt surface 8, and the up-and-down plug-in structure has a strong pressing force, so that the cold plate 6 can form a better initial fixation.

[0033] As a preferred embodiment; the cold plate 6 is inclined, and one end of the cold plate 6 close to the mounting plate 5 is an arc-shaped structure; it can be understood that the cold plate 6 is inclined to facilitate the downward flow of oil, and the arc-shaped setting of one end of the cold plate 6 can greatly reduce the occurrence of oil dripping.

[0034] As a preferred embodiment; a filter screen 11 is also fixedly installed inside the smoke hood 2, and a magnet column 12 is fixedly installed on the bottom surface of the filter screen 11, and the magnet column 12 is magnetically connected to the cold plate 6; the setting of the filter screen 11 has a protective effect to prevent the user's hand from reaching into the exhaust device, and secondly, it can continue to filter the oil smoke (after the oil smoke contacts the filter screen 11, it will also form oil droplets on the top surface of the cold plate 6) to reduce air pollution; in addition, the magnet column 12 is provided to further firmly fix the cold plate 6.

[0035] As a preferred embodiment, cards 13 are fixedly installed at both ends of the inner side of the bottom surface of the smoke hood 2, a gap is set between the card 13 and the smoke hood 2, and two symmetrical limiting columns 14 are set on the top surface of the card 13; it can be understood that by providing the card 13, it is convenient to connect the oil groove 15 with it, and at the same time, the limiting columns 14 are provided to further clamp the oil groove 15.

[0036] As a preferred embodiment; the smoke hood 2 is connected to the oil groove 15 through the card 13, and blocks 16 are fixedly installed at both ends of the top surface of the oil groove 15 and corresponding to the card 13, and the block 16 is provided with a connecting hole 17 for connecting the limiting column 14; when the oil groove 15 is engaged with the card 13 through the block 16, the block 16 will be inserted into the gap between the card 13 and the smoke hood 2, and under the action of external force, the block 16 will be slightly deformed, so that the limiting column 14 is engaged with the connecting hole 17 of the block 16.

[0037] As a preferred embodiment; a gasket 18 is connected to one end of the card 13, and the card 13 and the gasket 18 are an integrally formed structure. The gasket 18 is fixed to the smoke hood 2 by bolts, and a limited surface 19 is set at the front end of the gasket 18. The gasket 18 and the card 13 are a step structure; it can be understood that setting the gasket 18 and the card 13 as a step structure can create a gap between the card 13 and the smoke hood 2, and the setting of the limiting surface 19 can block one end of the block 16, so as to facilitate the precise installation of the oil tank 15.

[0038] As a preferred embodiment; an oil guide block 20 is provided inside the hood 2 and directly opposite the oil tank 15, and a plurality of oil drain holes 21 are provided on the oil guide block 20; by providing the oil guide block 20 and the oil drain holes 21, it is convenient for the oil to drip into the oil tank 15;

[0039] It is worth mentioning that when the oil on the top surface of the cold plate 6 is discharged, it can pass through the top surface of the cold plate 6 and the top surface of the mounting plate 5 to reach the oil guide block 20, and be discharged into the oil tank 15 through the oil discharge hole 21; when the oil on the bottom surface of the cold plate 6 is discharged, it can pass through the bottom surface of the cold plate 6 and the plug hole 7 at the mounting plate 5 (the plug hole 7 is an open structure) to reach the oil guide block 20, and be discharged into the oil tank 15 through the oil discharge hole 21.

[0040] As a preferred embodiment; the exhaust device includes a volute 22, a variable frequency motor (not shown) and fan blades (not shown), the volute 22 is fixedly installed inside the casing 1, the volute 22 is tilted, an air inlet 23 and an air outlet 24 are provided on the volute 22, a variable frequency motor is fixedly installed on the rear side of the volute 22, and the output end of the variable frequency motor is connected to the fan blades; it can be understood that the volute 22 is tilted, that is, the air inlet 23 is tilted to face the filter 11, so that the air suction effect is greatly improved, and the use of a variable frequency motor can make it quieter.

[0041] The working principle of the utility model is as follows: start the variable frequency motor, turn on the smoking mode, the oil smoke will continuously enter the hood 2 through the smoking port, the oil smoke will condense after contacting the cold plate 6, and the oil will flow through the cold plate 6 to the oil guide block 20 and the oil discharge hole 21, and finally be discharged into the oil tank 15;

[0042] The disassembly and installation principle of the cold plate 6 of the utility model is: the user puts both hands into the inside of the smoking port, and under the action of external force, pulls out the cold plate 6. The cold plate 6 is magnetically connected to the magnet column 12 and can be separated under the action of external force. Therefore, the disassembly process of the cold plate 6 is extremely simple, and the installation process is the opposite. In addition, the cold plate 6 is a plate-like structure, and can be directly soaked and cleaned after disassembly. There are no excessive gaps and hidden surfaces on the inside, and the cleaning difficulty is greatly reduced. The cold plate 6 can be cleaned quickly, which has an excellent use effect for "lazy" users.

[0043] It should be pointed out that the main problems in the prior art are: the existing oil suction rack has a relatively complex structure. During the process of disassembling and cleaning, due to the large number of gaps and hidden surfaces inside, it is difficult to clean and takes a long time, thereby reducing the use effect of the range hood;

[0044] Therefore, through the improvement of the present application, a cold plate 6 is used to replace the oil suction rack with an outwardly convex fan-shaped structure in the prior art. The cold plate 6 is a plate-like structure. After disassembly, it can be directly immersed and cleaned. The difficulty of cleaning is greatly reduced, and the cleaning time can be greatly shortened, thereby improving the use effect of the range hood.
