Description

Technical Field

[0001] The utility model relates to the technical field of kitchen and bathroom equipment, in particular to an oil leakage-proof range hood. Background Art

[0002] In the existing range hood, the shell encloses an exhaust cavity, and the fan is located in the exhaust cavity. When the fan is running, kitchen fumes enter the exhaust cavity from the exhaust port, and are then driven by the fan to be discharged to the outside from the exhaust pipe. However, some fumes are still driven by the wind flow to accumulate on the top surface of the exhaust cavity. As the fumes accumulate, they condense into oil droplets, and then pass through the exhaust port and drip onto the stove, polluting the kitchen environment.

[0003] Some manufacturers will set the top surface of the exhaust cavity to be inclined so that the oil droplets flow along the top surface to the side wall of the exhaust cavity. However, due to the presence of other components such as the fan in the exhaust cavity, the oil droplets may reach the connection position between the components and the shell when flowing along the top surface. At this time, the top surface is not flat, and there is a greater probability of dripping. This dripping position is usually not near the inner wall of the shell, but is likely to be above the smoke outlet, thereby dripping into the kitchen and causing pollution. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figure 1-Figure 5 As shown, an oil leakage-proof range hood according to an embodiment of the first aspect of the utility model comprises a shell 100, a fan 200 and an oil guide member 300, an exhaust cavity 110 is provided in the shell 100, a smoke collecting hood 400 is provided at the bottom of the shell 100, a plurality of smoke extraction ports 410 are provided on the smoke collecting hood 400, and the smoke extraction ports 410 are communicated with the exhaust cavity 110, the fan 200 is arranged in the shell 100 and located in the exhaust cavity 110, the oil guide member 300 is arranged on the top surface of the exhaust cavity 110, the oil guide member 300 is provided with an oil loading groove 310 for receiving oil droplets, and in the gravity direction, the projection of the oil outlet end 320 of the oil loading groove 310 is located outside the position where the smoke collecting hood 400 is provided with the smoke extraction port 410.

[0031] The range hood may be a T-shaped range hood, a wall-mounted range hood, etc. The housing 100 encloses an exhaust cavity 110. A control panel is disposed on the front end surface of the bottom of the housing 100. There may be multiple smoke hoods 400, which are also disposed on the bottom surface of the housing 100. Generally speaking, Figure 1-Figure 3As shown, the smoke collecting hood 400 can be rectangular, circular, etc. Taking a rectangle as an example, the smoke collecting hood 400 is concave to form an inward-shaped smoke collecting cavity. When the oil smoke rises to the smoke collecting hood 400, it will gather in the smoke collecting hood 400 and enter the exhaust cavity 110 through the smoke outlet 410. The front and rear side walls of the smoke collecting cavity can both be inclined surfaces, and the smoke outlet 410 is distributed on the inclined surfaces, and the edge of the smoke collecting hood 400 is used to connect with the shell 100, and the smoke outlet 410 is usually not provided.

[0032] Therefore, in some embodiments of the present invention, the projection of the oil outlet end 320 of the oil loading tank 310 is located at the edge of the smoke hood 400, so that the oil droplets can drip directly or along the inner wall of the shell 100, reducing the risk of dripping from the smoke outlet 410.

[0033] The fan 200 is arranged in the exhaust cavity 110. The fan 200 can be a cross-flow fan 200. A smoke exhaust port 120 is usually arranged on the top of the exhaust cavity 110. The fan 200 is installed in the smoke exhaust port 120, and one end of the smoke pipe 210 is connected to the smoke exhaust port 120, and the other end of the smoke pipe 210 extends to the outside.

[0034] In the oil leakage-proof range hood of the utility model, the fan 200 is running, which can drive the wind flow from the smoke outlet 410 into the exhaust cavity 110, and the oil smoke will enter the exhaust cavity 110 with the wind flow, and part of the oil smoke will accumulate on the top surface of the exhaust cavity 110. It should be noted that, since other components will be installed on the top surface of the exhaust cavity 110, the lower part of the position where the other components are located may be directly opposite to the smoke outlet 410. Even if the top surface is set as an inclined surface, oil droplets will flow to the connection position of other components and drip, and there is a risk of dripping into the smoke outlet 410. The oil guide 300 can be set At the connection position close to other components, the oil loading groove 310 plays a receiving role, and the oil droplets can flow to the oil loading groove 310. Even if the oil droplets drip in the oil loading groove 310, they will fall into the oil loading groove 310 instead of dripping from the smoke exhaust port 410. Then the oil droplets flow along the oil loading groove 310 to the oil outlet end 320, and the oil outlet end 320 is located outside the smoke exhaust port 410. Therefore, the oil droplets can only drip into the inside of the shell 100 and will not fall onto the stove. This design can guide the oil droplets and prevent the oil droplets from dripping during the flow, and is clean and reliable to use.

[0035] In some embodiments of the present invention, the cross-section of the oil guide member 300 is "L"-shaped, and the top of the oil guide member 300 is connected to the top surface of the exhaust cavity 110. The oil droplets can flow along the top surface of the exhaust cavity 110. After reaching the oil guide member 300, they flow down along the vertical part of the "L"-shaped oil guide member 300, and then flow in the horizontal wall surface. The horizontal wall surface here supports the oil droplets, and the oil droplets will not fall, but flow along the oil loading tank 310 to a suitable position and then drip.

[0036] In some embodiments of the present invention, Figure 4 , 5 As shown, the oil guiding member 300 includes a baffle 330 and an oil carrying member 340 , the baffle 330 is close to the top surface of the exhaust cavity 110 , the cross section of the oil carrying member 340 is “L” shaped, and the top end of the oil carrying member 340 is connected to the baffle 330 to form an oil carrying groove 310 .

[0037] The baffle 330 can be close to the top surface of the exhaust cavity 110, and can even completely cover the top surface of the exhaust cavity 110. Therefore, when part of the oil smoke rises to the top of the exhaust cavity 110, it condenses on the baffle 330 without polluting the shell 100 or corroding the shell 100. The baffle 330 and the oil carrier 340 are integrally connected, and the oil droplets flow along the baffle 330 to the oil carrier 340. Similarly, the oil droplets will also flow down along the vertical part of the "L"-shaped oil guide member 300, and then flow in the horizontal wall. The horizontal wall here supports the oil droplets, and the oil droplets will not fall.

[0038] In some embodiments of the present invention, Figure 5 As shown, the bottom wall of the oil carrying groove 310 is inclined downward along the extension direction of the oil carrying groove 310. Under the action of gravity, the oil droplets on the bottom wall of the oil carrying groove 310 will flow along the extension direction of the oil carrying groove 310, so that they can smoothly flow to the oil outlet end 320 for discharge without being deposited in the oil carrying groove 310. Generally speaking, the oil carrying groove 310 can extend along the edge of the connection position between the wall surface and the component in the exhaust cavity 110, so that when the oil droplets flow through the connection position between the component and the wall surface in the exhaust cavity 110, the convexity and concavity of the wall surface changes, so that the oil droplets can be carried by the oil carrying groove 310 after falling, and will not drip directly into the smoking port.

[0039] In some embodiments of the present invention, Figure 5 As shown, in order to prevent the oil droplets in the oil loading tank 310 from dripping from the end away from the oil outlet end 320, a stopper 350 is provided at the end of the oil loading tank 310 away from the oil outlet end 320. The stopper 350 can block the port of the end of the oil loading tank 310 away from the oil outlet end 320, so that the oil droplets are not easy to fall from there.

[0040] In some embodiments of the present invention, Figure 3 As shown, the top surface of the exhaust cavity is an inclined surface and is inclined downward toward the location of the oil guide member 300 , so that the oil droplets can more easily stay in the oil carrying groove 310 along the top surface of the exhaust cavity.

[0041] Specifically, the top surface of the exhaust cavity may be inclined relative to the installation surface where the fan 200 is installed, while the installation surface of the fan 200 is parallel to the horizontal plane; or, the top surface of the exhaust cavity is parallel to the installation surface where the fan 200 is installed. During the installation process, the range hood is installed on the wall through the installation bracket. In order to allow the oil smoke to enter from the smoke outlet 410 better, the installation bracket will make the range hood tilt from top to bottom toward the front, so that the top surface of the exhaust cavity is tilted relative to the horizontal plane. It can be understood that when the top surface of the exhaust cavity is tilted, the oil guide 300 installed on the top surface of the exhaust cavity will also tilt accordingly. Therefore, the lateral wall of the oil guide 300 will also tilt upward accordingly, which can further prevent oil dripping. .

[0042] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the housing 100 is provided with an oil storage cup 500 , and the smoke hood 400 is provided with an oil discharge port 420 , and the oil discharge port 420 corresponds to the oil storage cup 500 .

[0043] The oil storage cup 500 is usually located outside the exhaust cavity 110. The oil storage cup 500 can be in a long strip or barrel shape, etc., and is used to store oil smoke. The oil storage cup 500 is generally detachably connected to the housing 100 by screws or buckles, so that the user can remove the oil storage cup 500 for cleaning. Due to the guidance of the oil loading groove 310, the oil drops fall on the back of the smoke hood 400. The oil drops on the back of the smoke hood 400 can drip from the oil discharge port 420 to the oil storage cup 500 for collection, and will not overflow to other locations, so as to keep the use environment of the range hood clean and tidy.

[0044] In some embodiments of the utility model, the oil storage cup 500 has an oil storage tank 510 with an opening facing upward, and the oil drain port 420 is located above the notch position of the oil storage tank 510. The oil storage cup 500 and the smoke hood 400 are arranged in the air to facilitate disassembly and cleaning of the oil storage cup 500, and the oil drain port 420 is located above the notch position of the oil storage tank 510, so that oil droplets can accurately fall into the oil storage tank 510.

[0045] In some embodiments of the present invention, an oil guide groove 430 is provided on the back side of the smoke hood 400 facing the exhaust cavity 110, and the oil guide groove 430 is connected with the oil discharge port 420. The oil guide groove 430 on the back side of the exhaust cavity 110 has a certain depression, which can prevent oil droplets from leaking from the exhaust port 410 during the process of flowing along the surface of the back of the smoke hood 400. Specifically, the oil guide groove 430 can be surrounded by a rib arranged along the edge of the smoke hood 400 and the edge of the exhaust port 410. Due to the obstruction of the rib, oil droplets are not easy to overflow from the rib.

[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
