The oil screen is used as a front-end filtering device of the range hood and is used for realizing oil-smoke separation in the process of entering smoke, and reducing environmental pollution caused by oil-smoke entering the volute impeller and being discharged outdoors. And in the oil smoke separation process, along with attached to the long-term accumulation of oil fat on the oil net, can block up the oil net through-hole, influence the filter effect.

In order to solve the above technical problem, an embodiment of the present disclosure provides an oil screen, which is shown in fig. 1 to 6 and is disposed at a smoke suction port of a range hood, and includes an oil screen body 10 and a self-cleaning layer 20. The oil net body 10 is provided with a plurality of first net holes 11; the self-cleaning layer 20 is arranged on the oil net body 10 and is provided with second meshes 21 corresponding to the first meshes 11; the self-cleaning layer 20 includes a substrate layer 23 and an electrothermal layer 22 disposed outside the substrate layer 23.

In this embodiment, the oil screen is a metal oil screen, such as a stainless steel oil screen, an aluminum alloy oil screen, an alloy steel wire fiber oil screen, or the like. The metal oil net has better heat conductivity, and the cleaning effect on the oil net in the embodiment of the disclosure can be improved.

Here, the first mesh 11 refers to through holes of the oil net for oil smoke separation. The oil net is a barrier for blocking oil smoke, and a plurality of first meshes 11 on the oil net are used for filtering the oil smoke rising from the pot to the smoke machine direction, so that the filtered oil smoke continuously rises in the smoke machine and is discharged out of the machine body under the action of other components, and oil stains in the oil smoke can stay on the oil net.

The self-cleaning layer 20 is a layer structure arranged on the surface of the oil screen, and the oil stain on the oil screen is cleaned by arranging the self-cleaning layer 20. The second mesh 21 is a through hole on the self-cleaning layer 20 for avoiding the flue gas, so as to avoid the influence on the flue gas flow path after the self-cleaning layer 20 is arranged.

The substrate layer 23 is an insulating layer structure for realizing an insulating connection with a mounting position. Alternatively, the substrate layer 23 may be a nanoceramic layer structure. When the base layer 23 is of the nano ceramic layer structure, due to the characteristic of low heat conductivity, the heat insulation function is achieved, the self-cleaning layer 20 can be prevented from transferring heat to the cigarette machine body in a large amount when cleaning the oil screen, and self-cleaning efficiency is reduced.

The electric heating layer 22 is a structural layer arranged outside the substrate layer 23, and the electric heating layer 22 generates heat in a power-on state to clean the oil net.

Therefore, the oil smoke passes through the first meshes 11 and the second meshes 21 which are correspondingly arranged through the self-cleaning layer 20 structure which is attached to the oil net body. This automatically cleaning layer 20's base member layer 23 laminating oil net body 10 sets up, and base member layer 23 has insulating effect, can protect the user, avoids appearing the potential safety hazard. The electric heating layer 22 of the self-cleaning layer 20 is attached to the surface of the base layer 23 and used for heating in a power-on state, oil stains can be melted, the oil net can be comprehensively cleaned, the heating area is large, no cleaning blind area exists, and a good cleaning effect is achieved.

Alternatively, there is a one-to-one correspondence between the second meshes 21 and the first meshes 11, or one second mesh 21 corresponds to a plurality of first meshes 11.

For example, as shown in fig. 5, when the second mesh openings 21 corresponding to the first mesh openings 11 one by one are provided on the self-cleaning layer 20, the projections of the first mesh openings 11 and the second mesh openings 21 on the horizontal plane are overlapped, and this one-to-one correspondence makes the self-cleaning layer 20 and the oil net body 10 contact more sufficiently, and the self-cleaning effect is better.

For another example, as shown in fig. 6, the second mesh 21 provided on the self-cleaning layer 20 corresponds to at least two first mesh 11. The projection area of the plurality of first mesh openings 11 in the horizontal plane does not exceed the projection area of the second mesh openings 21 in the horizontal plane. This corresponding manner makes the self-cleaning layer 20 simple in structure and reduces manufacturing costs.

Optionally, the self-cleaning layer 20 is distributed continuously or at intervals on the oil network. When the self-cleaning layer 20 is continuously distributed on the oil net, the self-cleaning layer 20 can be set to be in the same shape as the oil net, the design cost of the template is reduced, and the cleaning effect is good. When the self-cleaning layers 20 are distributed on the oil screen at intervals, the oil screen cleaning schemes with multiple cleaning areas or different cleaning degrees can be realized by arranging the plurality of unconnected self-cleaning layers 20 on the oil screen.

Optionally, the electrothermal layer 22 comprises: graphene layer 221 and electrode layer 222. The electrode layer 222 is disposed outside the graphene layer 221 and connected to a power source through a wire.

The electrode layer 222 is a layered structure, and an electrode anode and an electrode cathode are disposed on the electrode layer 222 and are used for connecting two ends of a power supply. Here, the positive electrode and the negative electrode may be disposed on the same side of the graphene layer 221, or may be disposed on different sides.

The graphene layer 221 has a layer structure including graphene components, and has characteristics of high thermal conductivity, high electrical conductivity, and high strength.

When the positive electrode and the negative electrode in the electrode layer 222 are respectively electrified, the heat energy generated by the graphene layer 221 is uniformly radiated in a planar mode, so that the whole oil net can be uniformly heated, and the total effective electric heating energy conversion rate can reach more than 99%.

Optionally, self-cleaning layer 20 further comprises: the protective layer 24 is disposed outside the electrode layer 222. The electrode layer 222 can be protected, and the service life of the electrode layer 222 can be prolonged.

Optionally, the protective layer 24 includes an oleophobic scratch resistant layer. The oleophobic and scratch resistant layer can be made of nano silicon dioxide, the stability of the nano silicon dioxide is good, the scratch resistant effect can be achieved, and meanwhile, the nano silicon dioxide has an oleophobic function and can reduce oil stain adhesion.

Optionally, the self-cleaning layer 20 is disposed on a side of the oil screen body 10 away from the smoke suction port of the range hood, that is, the self-cleaning layer 20 is disposed on the smoke overflow side of the oil screen body 10.

After the power is switched on, the graphene layer 221 of the self-cleaning layer 20 can heat the oil net, so that oil stains adhered to the oil net are heated and softened or liquefied, and the oil net is discharged; or the heating temperature reaches the temperature for gasifying the grease, and the grease is directly gasified and discharged outdoors. The purpose of automatic cleaning is achieved.

Optionally, the self-cleaning layer 20 is disposed on both sides of the oil mesh body 10, i.e., the self-cleaning layer 20 is disposed on both the smoke-entering side and the smoke-overflowing side of the oil mesh body 10.

The self-cleaning layer 20 is arranged on the oil smoke inlet side of the oil screen body 10, and the outermost layer of the self-cleaning layer is a protective layer 24. Thus, the attachment of oil stains on the oil net can be reduced, the protection effect can be achieved, and the self-cleaning layer 20 is not easy to damage.

Optionally, the self-cleaning layer 20 is evenly distributed over the oil screen body 10. Thus, when the oil screen is electrified and self-cleaned, the self-cleaning layer 20 is uniformly distributed on the oil screen body 10, so that heat generated during heating can be uniformly distributed and radiated on the oil screen, and the oil screen is cleaned completely without dead angles.

Optionally, the thickness of the self-cleaning layer 20 becomes gradually larger from the middle of the oil net to the edge. The oil stain in the middle of the oil screen is more than that at the edge, so the design that the thickness of the self-cleaning layer 20 is gradually increased from the middle of the oil screen to the edge can ensure that the cleaning is more in place.

Optionally, the thickness of the self-cleaning layer 20 is 3-10 μm. Therefore, the cost can be reduced, the material waste can be reduced, the cleaning effect can be ensured not to be weakened, and the optimal cleaning effect can be achieved.

Optionally, the thickness of the electro-thermal layer 22 is 20-40% of the thickness of the self-cleaning layer 20. Therefore, the proportion of the electric heating layer 22 in the total structure of the self-cleaning layer 20 is ensured, the self-cleaning layer 20 has a better heating effect, and meanwhile, the self-cleaning layer 20 can be well protected during installation and use.

Fig. 2 is a structural diagram of an oil screen provided in an embodiment of the present disclosure, and as shown in fig. 2, the oil screen includes four side plates, namely a first side plate 121, a second side plate 122, a third side plate 123, and a fourth side plate 124.

Here, the first mesh 11 may be provided on one or more of the first side plate 121, the second side plate 122, the third side plate 123, and the fourth side plate 124.

Alternatively, the first mesh 11 is a bar-shaped mesh having both ends in a semicircular shape. Like this, filter the oil smoke through first mesh 11, when realizing the oil smoke filter effect, from structural appearance of having avoided clean dead angle. After the self-cleaning layer 20 is arranged on the oil net, the cleaning efficiency and the cleaning effect are further improved. In other embodiments of the present disclosure, the first mesh 11 may be a circular mesh or other polygonal mesh.

Alternatively, the oil screens are arranged in parallel between the first mesh holes 11 on the same side plate. Therefore, the oil smoke driven by the airflow can more uniformly and stably pass through the oil screen, a stable and uniform negative pressure area is formed at the lower side of the oil screen, and the oil smoke absorption efficiency is improved.

Optionally, in the case that the self-cleaning layer 20 is disposed on both the first side plate 121 and the second side plate 122 of the oil screen body 10, the thickness of the self-cleaning layer 20 gradually increases from the intersection line of the first side plate 121 and the second side plate 122 to the other edge side. Generally, when contacting the oil screen, the oil screen will contact the middle part first according to the direction of the oil smoke ascending path, so the oil dirt in the middle part of the oil screen is more than the oil dirt at the edge. Like this, through set up the self-cleaning layer 20 that thickness is thinner in intersect department, can obtain higher electric heat conversion efficiency for more heat is cleaned oil net middle part, and is clean more in place.
