[0003] The oil cup of the side-suction range hood disclosed in the prior art usually adopts an external design. The oil cup is installed at the bottom end of the outside of the smoke hood. The smoke hood is provided with a smoke inlet window. An oil mesh plate for separating grease is positioned at the smoke inlet window. The oil mesh plate is arranged at an angle. The oil condensed by the oil mesh plate will flow along the outer wall or inner wall of the smoke hood and finally drip into the oil cup in the form of oil droplets.
[0004] The above-mentioned external oil cup design requires that oil stains must pass through the outer wall or inner wall surface of the smoke hood before flowing into the oil cup, which extends the length of the oil path, causing grease to flow on the surface of the smoke hood and dirty the surface of the smoke collector shell, increasing the cleaning burden. In addition, the oil cup is located outside the smoke hood, and there is an obvious assembly gap between the oil cup and the smoke hood, which affects the overall consistency of the side-suction range hood, resulting in the problem that the side-suction range hood is not beautiful enough in appearance and the surface cleaning is not smooth. Moreover, since the oil cup is exposed, it is easy for dust to be contaminated on the oil cup and form oil stains, which increases the difficulty of cleaning. Utility Model Content

[0026] In order to make the technical problems solved by the utility model, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the utility model will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

Among them, the terms "first position" and "second position" are two different positions.
[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0029] The first preferred embodiment of the present invention is:
[0030] refer to Figure 1 to Figure 4 The oil collecting structure is the same as the structure of the existing side-suction range hood, and both include a smoke collecting hood 1. The smoke collecting hood 1 is hollow inside and is connected to the fan of the range hood. A side wall at one end of the smoke collecting hood 1 gradually tilts backward from top to bottom to form an inclined surface 11, and a smoke inlet window 12 is formed on the inclined surface 11. The smoke collecting hood 1 can suck the oil smoke into the fan through the smoke inlet window 12. An oil mesh plate 2 is connected to the smoke inlet window 12, and the oil mesh plate 2 is detachably connected to the smoke inlet window 12 by buckles, screws, magnetic attraction, etc. A plurality of mesh holes 21 are arranged on the oil mesh plate 2 to allow oil smoke to enter the smoke collecting hood 1. The grease particles absorbed by the oil mesh plate 2 will gather on the surface of the oil mesh plate 2 to form an oil flow, and the formed oil flow will flow downward along the surface of the oil mesh plate 2 under the action of gravity; the oil mesh plate 2 is made of flexible silicone material by hot pressing or injection molding into a mesh hollow shape, and an oleophobic layer is sprayed on the surface to give it a good oil guiding effect.
[0031] Compared with the prior art, the present invention has the following improvements:
[0032] refer to Figure 1 , Figure 2The oil collection structure also includes an oil cup 3, which is connected to the smoke inlet window 12 and positioned below the oil mesh plate 2. An oil storage tank 31 is provided on the oil cup 3. The notch of the oil storage tank 31 is upwardly aligned with the bottom of the oil mesh plate 2 and is connected to the bottom of the oil mesh plate 2, so that the oil flow gathered on the surface of the oil mesh plate 2 can drip downward along the surface of the oil mesh plate 2 into the oil storage tank 31.
[0033] From the perspective of oil circuit design, compared with the existing side-suction range hood which places the oil cup 3 outside the bottom of the smoke hood 1, the oil flow of the oil mesh plate 2 enters the oil cup 3 in the form of "external leakage" (the oil flows through the outer wall surface of the smoke hood 1) or "internal leakage" (the oil flows through the inner wall surface of the smoke hood 1). In the present disclosure, the oil cup 3 is built into the smoke inlet window 12, so that the oil cup 3 is directly connected to the oil mesh plate 2, and the grease separated and collected by the oil mesh plate 2 can directly enter the oil cup 3, thereby shortening the length of the oil circuit, avoiding the surface of the smoke hood 1 from contacting the oil flow to generate oil stains, and reducing the difficulty of cleaning.
[0034] From the perspective of product consistency: the oil cup 3 is built into the smoke inlet window 12, which improves the overall consistency of the smoke hood 1, makes the outer surface of the smoke hood 1 smoother to clean, and makes the range hood more beautiful. At the same time, since the existing side-suction range hood has an openable and closable smoke baffle, the smoke inlet window 12 can be closed when the range hood is idle to prevent external dust from entering the oil cup 3 and generating oil stains, thereby reducing the difficulty of cleaning.
[0035] In this embodiment, the oil mesh plate 2 and the oil cup 3 are arranged in the smoke inlet window 12 and completely cover the smoke inlet window 12 together, so that there is no gap between the oil cup 3, the oil mesh plate 2 and the smoke inlet window 12, ensuring that the oil smoke enters the smoke hood 1 alone through the oil mesh plate 2, so that the oil mesh plate 2 can fully filter the oil smoke.
[0036] For the convenience of cleaning and maintenance, in this embodiment, the oil cup 3 is detachably positioned in the smoke inlet window 12, so that the oil cup 3 can be removed and cleaned separately, reducing the difficulty of cleaning. There are generally two ways to implement "the oil cup 3 is detachably positioned at the smoke inlet window 12". In the first way, the oil cup 3 is detachably connected to the oil mesh plate 2 and then positioned on the smoke inlet window 12, or the oil cup 3 is detachably connected to the smoke inlet window 12 and then positioned on the smoke inlet window 12.
[0037] There are various forms in which the oil cup 3 can be detachably connected to the smoke inlet window 12 or the oil mesh plate 2. For example, the oil cup 3 can be detachably connected to the smoke inlet window 12 by connecting the smoke hood 1 or the oil mesh plate 2 through fasteners such as screws and bolts, or magnetic suction parts are installed on the oil cup 3, the smoke hood 1 or the oil mesh plate 2, respectively, so that the oil cup 3 can be detachably installed on the smoke inlet window 12 in the form of magnetic suction. However, when the former detachable connection method based on fasteners is adopted, considering that the fasteners used by the oil cup 3 are usually threaded fasteners such as bolts and screws, such fasteners are small in size and have many grooves on the surface, oil stains will be deposited on the fasteners and parts installation holes after long-term use, which is difficult to completely remove, which will seriously affect the user experience during secondary loading and unloading, and the installation is more troublesome, which is easy to cause the loss of parts; and when the latter detachable connection method based on magnetic suction is adopted, since the magnetic suction parts need to be additionally installed in the oil cup 3 or the oil storage tank 31, the production cost is indirectly increased.
[0038] In order to simplify the installation process, reduce the cleaning difficulty, improve the user's experience in installing the oil cup 3 and reduce the production and assembly cost, this implementation case improves the structure and specific positioning method of the oil cup 3 based on the technical solution that the oil cup 3 is built into the smoke inlet window 12.
[0039] refer to Figure 2 , Figure 4 The oil cup 3 includes a bottom plate 32 and a plurality of side plates 33 that are enclosed and connected to the edge of the bottom plate 32. The bottom plate 32 and the plurality of side plates 33 together enclose the above-mentioned oil storage tank 31. The notch of the oil storage tank 31 is formed with a first buckle 34. The bottom of the oil mesh plate 2 is provided with a second buckle 24 that is adapted to be engaged with the first buckle 34. During installation, the oil mesh plate 2 can be first installed on the top of the smoke inlet window 12. The bottom of the oil mesh plate 2 and the part of the smoke inlet window 12 that is not covered by the oil mesh plate 2 form a new window with a smaller area. Then, one end of the oil cup 3 can be tilted downward and pushed horizontally into the smoke inlet window 12 as a whole, and the first buckle 34 on the oil storage tank 31 is engaged with the second buckle 24, so that the oil cup 3 can be fixed to the bottom of the oil mesh plate 2.
[0040] refer to Figure 2 In order to make the oil cup 3 more stable when detachably connected to the oil screen plate 2 and reduce the vertical support pressure between the first buckle 34 and the second buckle 24, in this embodiment, a support surface 13 is provided in the smoke inlet window 12, and the support surface 13 can vertically limit the oil cup 3 by abutting against the bottom plate 32 of the oil cup 3. In order to facilitate production and make the contact between the oil cup 3 and the smoke inlet window 12 closer, the support surface 13 is directly formed on the bottom edge of the smoke inlet window 12.
[0041] refer to Figure 2In this embodiment, the first buckle 34 is formed on the inner wall of one end of the oil storage tank 31, and the second buckle 24 is formed on the outer side surface 22 of the oil mesh plate 2 (the side of the oil mesh plate 2 away from the smoke inlet window 12 and exposed to the user's field of vision is the outside). When in use, since the second buckle 24 is exposed on the outer side surface 22 of the oil mesh plate 2, the blind area of the field of vision is small, and it is more convenient for the user to snap the first buckle 34 onto the second buckle 24 from the outside to the inside during the installation process, which helps to reduce the difficulty of operation. In addition, since the oil cup 3 is snapped onto the oil mesh plate 2 from the outside to the inside through the first buckle 34, the notch of the oil storage tank 31 can completely cover the oil mesh plate 2. The bottom of the oil mesh plate 2 is formed with the first oil circuit and the second oil circuit to match the oil discharge form of the oil mesh plate 2 at different smoke intake amounts, specifically: when the smoke intake amount of the smoke intake window 12 is large, the oil flow is mainly formed on the inner side surface 23 of the oil mesh plate 2, and the oil flows along the inner side surface 23 of the oil mesh plate 2 and passes through the bottom of the oil mesh plate 2 into the oil storage tank 31 in the form of oil droplets, that is, the first oil circuit 4; and when the smoke intake amount of the smoke intake window 12 is small, the oil flow is mainly formed on the outer side surface 22 of the oil mesh plate 2, and the oil flows along the outer side surface 22 of the oil mesh plate 2 and passes through the bottom of the oil mesh plate 2 into the oil storage tank in the form of oil droplets, that is, the second oil circuit 5.
[0042] When the smoke intake of the smoke inlet window 12 is small, the oil flow on the outer side 22 of the oil mesh plate 2 needs to pass through the engagement gap between the first buckle 34 and the second buckle 24 and then enter the oil cup 3 when flowing through the second oil passage 5 and the bottom of the oil mesh plate 2. When the first buckle 34 and the second buckle 24 are closely engaged or the indoor temperature is low and the oil fluidity is poor, the oil passage is easily blocked, which may cause oil overflow. Figure 4 In this embodiment, a first notch 35 is formed at one end of the first buckle 34 away from the side plate 33 for the oil flow to pass directly, and the second buckle 24 is provided with a second notch 25 which is adapted to be connected with the first notch 35. When the smoke intake of the smoke inlet window 12 is small, when the oil mesh plate 2 discharges oil through the second oil passage 5, the oil flow can be directly and smoothly discharged into the oil storage tank 31 through the first notch 35 and the second notch 25, thereby preventing grease from clogging and overflowing and polluting the stove environment.
[0043] The second specific implementation of the present invention is:
[0044] refer to Figure 1 , a side suction range hood, the range hood specifically includes the oil collection structure in the first preferred embodiment. Through the above design, the side suction range hood has strong overall consistency and the exterior is easy to clean.
[0045] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
