Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to an oil guiding component and an oil fume treatment device for a range hood. Background Technology

[0002] An integrated cooktop is a kitchen appliance that combines a range hood, gas stove, disinfection cabinet, steam oven, or storage cabinet into one unit. It has advantages such as saving space and being energy-efficient and environmentally friendly, and is very popular among users.

[0003] Currently, the oil cup for collecting grease in integrated cooktops is located below the oil fume separator, inside the cabinet. Users often cannot easily check if the cup is full, frequently resulting in grease overflow and staining the cabinet. In existing technology, an oil collection trough is located below the oil fume separator, connected to the oil cup assembly at the bottom of the cooktop via an oil guide pipe. Grease flows into the oil cup assembly for collection through the guide pipe. The guide pipe uses a flexible hose, but due to the large horizontal distance between the oil outlet of the collection trough and the oil cup assembly, the guide pipe needs to be bent to achieve the connection. However, if the flexible hose is bent at a large angle during installation, it increases the resistance to oil drainage, causing poor drainage. Utility Model Content

[0004] The first technical problem solved by this utility model is to provide an oil guiding component that can effectively solve the problem of poor oil drainage caused by large bending angles during the installation of existing oil guiding pipes; and ensure the smooth flow of oil in the oil guiding component.

[0005] The second technical problem solved by this utility model is to provide an oil fume treatment device for a range hood, which can effectively solve the problems of high oil discharge resistance and poor oil discharge in existing oil fume treatment devices, so as to reduce oil discharge resistance and avoid oil stains from contaminating the cabinet.

[0006] The first technical problem mentioned above is solved by the following technical solution:

[0007] Oil guiding assembly, including:

[0008] Oil guide tube, wherein the oil guide tube is a flexible tube;

[0009] A bellows is fitted over the oil guide pipe, and the radius difference between the bellows and the oil guide pipe is less than or equal to 10 mm.

[0010] The oil guiding component described in this utility model has the following advantages compared with the prior art:

[0011] The oil guiding assembly provided by this utility model includes an oil guiding pipe and a corrugated pipe. The corrugated pipe is sleeved outside the oil guiding pipe, and the radius difference between the corrugated pipe and the oil guiding pipe is controlled to be less than or equal to 10mm. By controlling the radial fit clearance between the corrugated pipe and the oil guiding pipe, a uniform circumferential constraint force can be applied to the oil guiding pipe through the corrugated pipe, while avoiding support failure caused by excessive clearance. This ensures that the oil guiding pipe can bend within a certain range, so that during the installation process, it can meet the installation requirements when the connection positions at both ends of the oil guiding pipe are widely spaced in the horizontal direction, and also avoid large bending of the oil guiding pipe during installation, which would reduce the flow cross-sectional area of ​​oil and increase the flow resistance, resulting in poor oil drainage.

[0012] In one embodiment, the oil guiding assembly further includes a heating element disposed between the bellows and the oil guiding pipe.

[0013] In one embodiment, the oil guiding assembly further includes an insulating component wrapped around the outer wall of the oil guiding pipe, and the heating component wrapped around the insulating component. The radius difference between the corrugated pipe and the oil guiding pipe is 5mm to 10mm.

[0014] In one embodiment, the oil guiding assembly further includes an oil pipe connector, which includes a first connector and a second connector arranged at an obtuse angle. The first connector is used to connect to an oil receiving groove, and the second connector is connected to the oil inlet end of the oil guiding pipe.

[0015] In one embodiment, the oil outlet end of the oil guide pipe is suspended inside the bellows.

[0016] In one embodiment, the corrugated pipe includes a corrugated section and a smooth section, the smooth section being close to the oil outlet end of the oil guide pipe, and the oil outlet end of the oil guide pipe being suspended between the corrugated section and the smooth section.

[0017] In one embodiment, the oil guiding assembly further includes an oil guiding seat, one end of which is provided with a first connecting pipe connected to the optical tube segment, and the other end is provided with a second connecting pipe, which is located at the bottom of the oil guiding seat and extends downward.

[0018] The second technical problem mentioned above is solved by the following technical solution:

[0019] The range hood's fume treatment device includes an oil guiding component as described in the above scheme, wherein the oil outlet of the oil guiding component is connected to a drain pipe.

[0020] The fume treatment device for a range hood includes an oil cup assembly and an oil guiding assembly as described in any of the above embodiments, wherein the oil guiding assembly is connected to the oil cup assembly.

[0021] In one embodiment, the oil cup assembly includes an oil cup and an oil cup support. The oil cup is removably disposed within the oil cup support. A communication port is provided on the top plate of the oil cup support. The length of the top plate is greater than the length of the oil cup, and the communication port is located above the oil cup.

[0022] The oil fume treatment device for the range hood described in this utility model has the following advantages compared with the prior art:

[0023] The oil fume treatment device for the range hood provided by this utility model includes the aforementioned oil guiding component, which can prevent the oil guiding pipe from undergoing large bends during installation, thus avoiding increased oil drainage resistance.

[0037] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] This utility model provides an oil fume treatment device for a range hood. This oil fume treatment device can be applied to an integrated range hood or to a range hood in an integrated cooktop. The specific embodiment of this utility model is described using an integrated cooktop range hood as an example.

[0040] Example 1:

[0041] like Figures 1-3As shown, the range hood includes a body 200. The fume treatment device of the range hood provided in this embodiment includes an oil collecting trough 1, an oil guiding assembly 2, and an oil cup assembly 3. The oil collecting trough 1 is located inside the body 200, and the body 200 is provided with a smoke inlet. An oil fume separation screen is installed on the smoke inlet, and the extracted oil fumes are separated under the action of the oil fume separation screen. The oil collecting trough 1 is located at the bottom of the oil fume separation screen to receive the separated oil. The oil cup assembly 3 is located at the bottom of the body 200. The oil accumulated in the oil collecting trough 1 is guided by the oil guiding assembly 2 to the oil cup assembly 3 located at the bottom of the body 200 for collection. The oil cup assembly 3 is located outside the cabinet 100, so even if oil overflows from the oil cup assembly 3, it will not contaminate the cabinet 100.

[0042] In addition, for integrated cooktops, placing the oil cup assembly 3 at the bottom of the body 200, compared to placing the oil cup assembly 3 inside the body 200, means that the oil cup assembly 3 does not occupy the height space of the cabinet 100, making it easier to embed larger appliances into the body 200.

[0043] This embodiment also provides an oil guiding assembly, applied to the oil fume treatment device of the aforementioned range hood. The oil guiding assembly 2 includes an oil guiding pipe 21 and a corrugated pipe 22. The oil guiding pipe 21 is a flexible hose, and the corrugated pipe 22 is sleeved outside the oil guiding pipe 21, with the radius difference between the corrugated pipe 22 and the oil guiding pipe 21 being less than or equal to 10 mm. By controlling the radial fit clearance between the corrugated pipe 22 and the oil guiding pipe 21, a uniform circumferential constraint force can be applied to the oil guiding pipe 21 through the corrugated pipe 22, while avoiding support failure caused by excessive clearance, thus ensuring that the oil guiding pipe 21 can bend within a certain range. During the installation of the oil guiding pipe 21, it can meet the installation requirements when the connection positions at both ends of the oil guiding pipe 21 are widely spaced in the horizontal direction, while also preventing large bends in the oil guiding pipe 21 during installation, which would reduce the flow cross-sectional area of ​​oil within the oil guiding pipe 21, increase flow resistance, and cause poor oil drainage.

[0044] Furthermore, the oil inlet end of the oil guide pipe 21 is located outside the bellows 22, and the oil outlet of the oil receiving groove 1 is connected to the oil inlet end of the oil guide pipe 21. Since the oil inlet end of the oil guide pipe 21 is located outside the bellows 22 and is not rigidly constrained by the bellows 22, when the installation space is narrow or there are obstacles, the installer does not need to forcibly match the angle of the bellows 22; the oil circuit can be connected through the natural bend of the oil inlet end of the oil guide pipe 21.

[0045] The oil guiding assembly provided in this embodiment achieves a balance between installation flexibility and oil circuit smoothness while ensuring structural stability through a composite design of rigid support and flexible connection. It is particularly suitable for oil circuit system scenarios with limited space or requiring frequent maintenance.

[0046] The oil guide tube 21 is a smooth, flexible hose. The surface of the flexible hose is treated with plasma polishing or a polymer coating to make the surface smoother, thereby reducing the resistance to oil flow. Preferably, the flexible hose is made of fluororubber composite material.

[0047] In one embodiment, the oil guiding assembly 2 further includes a heating element 23, which is disposed between the bellows 22 and the oil guiding pipe 21. The heating element 23 is a heating wire, which generates heat to ensure that the oil guiding pipe 21 is always in an environment of 40°C to 50°C, preventing oil from solidifying and clogging the oil passage, and further ensuring smooth oil drainage.

[0048] In one embodiment, the oil guiding assembly 2 further includes an insulating element 24, which wraps around the outer wall of the oil guiding pipe 21. The heating element 23 is wound around the insulating element 24, and the radius difference between the corrugated pipe 22 and the oil guiding pipe 21 is 5mm to 10mm. The insulating element 24 isolates the heating wire from the oil guiding pipe 21, preventing direct contact and heating between the heating wire and the oil guiding pipe 21, which could cause the oil guiding pipe 21 to melt due to high temperature and leak oil. At the same time, the insulating element 24 wraps around the oil guiding pipe 21, providing insulation and preventing rapid heat loss from the oil guiding pipe 21. In this embodiment, the radius difference between the corrugated pipe 22 and the oil guiding pipe 21 is 5mm to 10mm, ensuring sufficient clearance for the installation of the insulating element 24 and avoiding excessive clearance that could lead to the failure of the corrugated pipe 22's support.

[0049] Optionally, the insulating element 24 can be insulating cotton. The corrugated pipe 22 is located outside the heating element 23, which can further prevent heat loss from the oil guide pipe 21, reduce energy consumption, and provide an outer layer of protection for the heating wire.

[0050] In one embodiment, the oil guiding assembly 2 further includes an oil pipe connector 25, which includes a first connector 251 and a second connector 252 arranged at an obtuse angle. The first connector 251 is used to connect to the oil receiving groove 1, and the second connector 252 is connected to the oil inlet end of the oil guiding pipe 21. The obtuse-angled oil pipe connector 25 connects the oil receiving groove 1 and the oil inlet end of the oil guiding pipe 21, forming a smooth oil guiding path. At the same time, the obtuse-angled oil pipe connector 25 can also compensate for the bending angle of the oil guiding pipe 21, avoiding excessive bending of the oil guiding pipe 21 when the oil inlet end of the oil guiding pipe 21 is connected to the oil receiving groove 1, which would increase the resistance to oil flow.

[0051] In one embodiment, the oil outlet end of the oil guide pipe 21 is suspended inside the corrugated pipe 22. Preferably, the corrugated pipe 22 is made of metal and has a certain rigidity. After the corrugated pipe 22 is fitted onto the oil guide pipe 21, there is a certain gap between the end of the corrugated pipe 22 near the oil receiving groove 1 and the oil inlet end of the oil guide pipe 21. This end is not connected to the oil guide pipe 21 and the oil receiving groove 1 and is a free end. The end of the corrugated pipe 22 away from the oil receiving groove 1 is connected to the oil cup assembly 3, and the oil flows into the corrugated pipe 22 through the oil outlet end of the oil guide pipe 21. Since one end of the corrugated pipe 22 is not sealed, it avoids the formation of air pressure between the corrugated pipe 22 and the oil cup assembly 3 due to the good sealing of the oil cup assembly 3, which would hinder the discharge of oil sludge and ensure that the oil sludge in the oil guide pipe 21 can flow smoothly into the corrugated pipe 22.

[0052] In one embodiment, the bellows 22 includes a corrugated section 221 and a smooth section 222. The smooth section 222 is located near the oil outlet of the oil guide pipe 21, and the oil outlet of the oil guide pipe 21 is suspended between the corrugated section 221 and the smooth section 222. The corrugated section 221 mainly supports the oil guide pipe 21, and the smooth section 222 is connected to the oil cup assembly 3, which ensures the sealing of the connection between the corrugated pipe 22 and the oil cup assembly 3, preventing oil leakage from the connection between the corrugated pipe 22 and the oil cup assembly 3. Suspending the oil outlet of the oil guide pipe 21 between the corrugated section 221 and the smooth section 222 can prevent oil from being unable to flow out of the oil guide pipe 21 due to air pressure resistance, and also prevent oil from flowing into the folds of the corrugated section 221 and accumulating.

[0053] Furthermore, the corrugated pipe 22 is a stainless steel corrugated pipe. Stainless steel corrugated pipes are corrosion-resistant and rigid, providing both support and resistance to aging, thus extending their service life.

[0054] In one embodiment, such as Figures 4-6 As shown, the oil guiding assembly 2 also includes an oil guiding seat 26. One end of the oil guiding seat 26 is provided with a first connecting pipe 261 that connects to the light tube section 222, and the other end is provided with a second connecting pipe 262. The second connecting pipe 262 is located at the bottom of the oil guiding seat 26 and extends downward. The oil guiding seat 26 serves as a connecting bridge between the corrugated pipe 22 and the oil cup assembly 3, which can smoothly guide the oil in the oil guiding pipe 21 to the oil cup assembly 3 for collection, and can prevent oil from spilling during the process of cleaning the oil collected in the oil cup assembly 3.

[0055] In this embodiment, the oil cup assembly 3 includes an oil cup 31 and an oil cup support 32. The oil cup 31 is retractably disposed within the oil cup support 32. A connecting port 3221 is provided on the top plate 322 of the oil cup support 32. The length of the top plate 322 is greater than the length of the oil cup 31, and the connecting port 3221 is located above the oil cup 31. Specifically, along the width direction of the body 200, the first connecting pipe 261 extends into the smooth section 222 of the corrugated pipe 22 and is sealed to the corrugated pipe 22. The oil outlet end of the suspended oil guide pipe 21 is directly opposite the first connecting pipe 261, allowing oil to drip directly into the first connecting pipe 261. The oil guide seat 26 is fixed to the top plate 322 of the oil cup support 32 by screws. The second connecting pipe 262 is inserted into the connecting port 3221, allowing the oil in the oil guide seat 26 to drip directly into the oil cup 31. Figure 5 As shown, without the oil guide seat 26, the length of the oil cup 31 is D2; with the oil guide seat 26, the length of the oil cup 31 is D1. D1 is much smaller than D2, making it easier for the user to maintain balance when pulling out the oil cup 31 and preventing oil spillage from the oil cup 31.

[0056] Continue to refer to Figure 1 and Figure 3 A baseboard 300 is installed between the front of the machine body 200 and the ground. The baseboard 300 has a notch. An oil cup support 32 is fixed to the bottom of the machine body 200, and one end of the oil cup support 32 is engaged with the notch. An accommodating groove 321 is provided inside the oil cup support 32, and the oil cup 31 is retractable and installed in the accommodating groove 321. The oil cup support 32 also includes two side plates 323 and a front plate 324 communicating with the accommodating groove 321. The top plate 322 and the two side plates 323 enclose the accommodating groove 321. The two side plates 323 are fixedly connected to the machine body 200 by fastening screws. The front plate 324 is engaged in the notch. The front end of the oil cup 31 is set as a push-pull plate 311. The push-pull plate 311 has a hand latch groove 3111. The user can place their hand in the hand latch groove 3111 to pull out or push in the oil cup 31 for easy operation. Oil stains are collected by an oil cup 31 located at the bottom of the unit 200. Users can pull out the oil cup 31 from the notch in the baseboard 300, empty the oil cup 31, and then push the cleaned oil cup 31 into the oil cup support 32 for easy cleaning. Even if the oil cup 31 overflows when full, it will only stain the floor and will not stain the cabinet 100.

[0057] Furthermore, the oil cup 31 is made transparent so that users can observe whether the oil cup 31 is full of oil and clean the oil cup 31 in time after it is full to avoid overflow and contamination of the ground.

[0058] Example 2:

[0059] like Figure 7As shown, this embodiment provides an oil fume treatment device for a range hood, which has a structure that is basically the same as the oil fume treatment device provided in Embodiment 1. For the same structure, it will not be described in detail here.

[0060] The difference lies in the fact that the oil fume treatment device of the range hood provided in this embodiment has the oil guiding component 2 connected to the drain pipe 400. The drain pipe 400 is located between the bottom of the body 200 and the ground, and behind the baseboard 300. The bare section 222 of the corrugated pipe 22 is directly inserted into the drain pipe 400. After the oil sludge generated by the body 200 accumulates in the oil receiving tray 1, it is directly discharged into the drain pipe 400 of the user's kitchen through the oil guiding component 2, without any oil accumulation.

[0061] The oil fume treatment device for the range hood provided in this embodiment does not require the installation of the oil cup assembly 3, does not require cleaning of oil stains, and will not contaminate the cabinet 100 and the floor, saving time and effort while reducing costs.

[0062] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
