Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and in particular to range hoods. Background Technology

[0002] In modern kitchen environments, range hoods are typically used to exhaust fumes and other gases outdoors to reduce pollution. In related technologies, an oil cup is used to collect droplets from the smoke collection component. A certain gap exists between the oil cup and the smoke collection component. In moving range hoods, the gap between the oil cup and the smoke collection component becomes inconsistent due to uneven stress on the moving component. Summary of the Invention

[0003] Embodiments of this application provide a range hood that can improve the problem of uneven gaps when the range hood is closed.

[0004] This application provides a range hood. The range hood includes a frame, a smoke collection assembly, and an oil cup. The smoke collection assembly is mounted on the frame. The oil cup is mounted on the smoke collection assembly. When the range hood is in the open state, in the arrangement direction of the frame and the smoke collection assembly, the portion of the oil cup closer to the front of the range hood is closer to the smoke collection assembly than the portion of the oil cup closer to the rear of the range hood.

[0005] Optionally, the oil cup includes a main body and a side plate. The main body is bent and the side plates are located at both ends of the main body. The main body and the side plates form an accommodating space with an opening facing the smoke collection assembly. When the range hood is in the open state, the distance between the end face of the side plate with the opening and the smoke collection assembly gradually decreases in the direction from the rear to the front of the range hood.

[0006] Optionally, the range hood also includes a mounting bracket, which is fixedly connected to the smoke collection assembly, and the oil cup is detachably connected to the mounting bracket. The mounting bracket includes a main body and a mounting part disposed on the side of the main body near the smoke collection assembly. The height of the part of the mounting part near the rear of the range hood protruding from the main body is greater than the height of the part of the mounting part near the front of the range hood protruding from the main body. The oil cup is mounted on the main body, and the mounting part is installed and cooperates with the smoke collection assembly.

[0007] Optionally, the range hood also includes a mounting bracket, which is fixedly connected to the smoke collection assembly, and the oil cup is detachably connected to the mounting bracket. The mounting bracket is provided with a mounting groove with an opening facing the front of the range hood. The oil cup is installed in the mounting groove from the opening. When the range hood is in the open state, the portion of the mounting groove near the rear of the range hood is further away from the smoke collection assembly than the portion of the mounting groove near the front of the range hood.

[0008] Optionally, the smoke collection assembly includes a smoke collection body and a lifting body, the lifting body being movably connected to the smoke collection body to open or close the smoke machine; the smoke machine also includes a drive device, the drive device being installed on the smoke collection body and drivenly connected to the lifting body, the drive device being connected to the rear part of the lifting body near the smoke machine.

[0009] Optionally, there is a gap between the lifting body and the smoke collection body, and a seal is installed inside the smoke collection body to seal the gap.

[0010] Optionally, the smoke collection body is fitted outside at least part of the lifting body, and the seal has an assembly part and a sealing part. The assembly part is installed on the part of the lifting body located inside the smoke collection body, and the sealing part extends obliquely from the assembly part toward the smoke collection body in the direction of the assembly part toward the smoke collection body.

[0011] Optionally, the smoke collection body has a bent portion, which includes an installation section, an extension section, and a connecting section connecting the installation section and the extension section. The extension section is closer to the interior of the smoke collection assembly than the installation section, and the distance between the sealing portion and the installation section is smaller than the distance between the extension section and the installation section.

[0012] Optionally, the drive device includes a first mounting part and a second mounting part. The first mounting part is used to cooperate with the smoke collection body, and the second mounting part is used to cooperate with the lifting body. The first mounting part cooperates with the smoke collection body through at least two different first mounting surfaces, and the second mounting part cooperates with the lifting body through at least two different second mounting surfaces.

[0013] Optionally, the smoke collection body is provided with a slide rail, and the lifting body is provided with a sliding part. The sliding part cooperates with the slide rail to realize the movable connection between the lifting body and the smoke collection body; wherein, the end of the slide rail near the frame is provided with a buffer pad facing the sliding part.

[0014] The beneficial effects of this application are as follows: Unlike the prior art, by setting the oil cup closer to the front of the range hood than the oil cup closer to the rear of the range hood when the range hood is open, it can compensate for the technical problem that when the range hood is closed, the gap between the oil cup closer to the front of the range hood and the smoke collection assembly is larger than the gap between the oil cup closer to the rear of the range hood and the smoke collection assembly due to uneven driving force. This improves the technical problem of uneven gap between the oil cup and the smoke collection assembly and also helps to enhance the aesthetics of the range hood when it is closed.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0026] In related technologies, sport-type range hoods can be opened or closed via methods such as lifting. These range hoods utilize a drive mechanism for lifting. The front of the range hood needs to form the main air inlet to draw in cooking fumes, so the drive connection of the drive mechanism needs to be close to the rear to allow more space for air intake at the front. However, this rearward drive connection results in a greater driving force on the grease cup near the rear of the range hood compared to the front during closing and lifting. Consequently, when the range hood is closed, the portion of the grease cup near the front is lower than the portion near the rear, leading to uneven gaps between the grease cup and the fume collection assembly. To address these technical problems, this application provides the following embodiments.

[0027] Combination Figure 1This application provides a range hood 1. The range hood 1 includes a frame 10, a smoke collection assembly 20, and an oil cup 30. The smoke collection assembly 20 is mounted on the frame 10 and connected to the frame 10. The range hood 1 can be mounted on a wall via the frame 10 or the smoke collection assembly 20. The frame 10 is provided with an air outlet (not shown), which can be connected to an external flue via a pipe. The frame 10 includes a housing, a volute (not shown), and a centrifugal impeller (not shown) disposed within the housing. The centrifugal impeller is disposed within the volute. The volute can communicate with the interior of the smoke collection assembly 20, and the negative pressure generated by the rotation of the centrifugal impeller can drive the gas in the smoke collection assembly 20 to the air outlet for discharge. A main air inlet 201 is provided on the front side of the smoke collection assembly 20, which is correspondingly arranged with the stove. The main air inlet 201 can draw in the oil fumes generated during cooking, and then discharge them through the air outlet after passing through the smoke collection assembly 20 and the frame 10. The oil cup 30 is installed on the smoke collection assembly 20. The oil cup 30 can collect the dripping liquid inside the smoke collection assembly 20, thereby reducing the dripping liquid onto the stove and splashing everywhere.

[0028] Combination Figure 1 and Figure 2 In some embodiments, the smoke collection assembly 20 includes a smoke collection body 21 and a lifting body 22, the lifting body 22 being movably connected to the smoke collection body 21 to open or close the smoke machine 1. Figure 1 and Figure 2 The structure of the range hood 1 in the open state is shown. The lifting body 22 and the smoke collection body 21 enclose a main air inlet 201. The main air inlet 201 is correspondingly positioned to the cooktop, and it draws in cooking fumes, which are then discharged through the exhaust vent after passing through the smoke collection assembly 20 and the frame 10. The lifting body 22 can control the opening and closing of the main air inlet 201 by raising and lowering it. Optionally, the lifting body 22 can also control the distance between the main air inlet 201 and the cooktop by raising and lowering it. The lifting body 22 can also improve the aesthetics of the range hood 1 when closed by moving the main air inlet 201. The oil cup 30 is installed on the side of the lifting body 22 away from the smoke collection body 21.

[0029] In some embodiments, an air collecting port 202 is also formed on the smoke collecting body 21, and the air collecting port 202 is located on the side of the main air inlet 201 near the frame 10. The air collecting port 202 can draw in gas that has not been drawn in by the main air inlet 201, thereby increasing the smoke extraction capacity of the smoke hood 1. The air collecting port 202 may be oriented in the same direction as the main air inlet 201. The air collecting port 202 may also be oriented at an angle to the main air inlet 201.

[0030] In some embodiments, the smoke collection body 21 includes a side suction section and a top suction section that cooperate with the lifting body 22. The main air inlet 201 formed by the side suction section and the lifting body 22 can draw in cooking fumes from the side of the stove. The top suction section extends from the side suction section toward the front of the range hood 1 and is provided with an air collection port 202, which is downwardly positioned, and can draw in cooking fumes from the top surface of the stove. Optionally, in some embodiments, a guide plate is provided corresponding to the air collection port 202, which can improve the negative pressure distribution at the air collection port 202, thereby improving the smoke collection capacity of the air collection port 202.

[0031] In some embodiments, the range hood 1 has a front side and a rear side, and the rear side of the range hood 1 can abut against a wall or a flat surface. When the range hood 1 is in the open state, the smoke collection body 21 is disposed between the frame 10 and the lifting body 22, and the main air inlet 201 is farther away from the frame 10 than the air collection inlet 202. This arrangement brings the main air inlet 201 closer to the cooktop, enabling it to quickly draw in most of the cooking fumes. The air collection inlet 202, being farther away from the cooktop than the main air inlet 201, can draw in any cooking fumes that the main air inlet 201 fails to completely draw in. Through this method, cooking fumes can be drawn in in sections, improving the smoke extraction effect of the range hood 1.

[0032] In some embodiments, combined with Figure 8 The range hood 1 also includes a drive unit 70, which is mounted on the smoke collection body 21 and drivenly connected to the lifting body 22. The drive shaft of the drive unit 70 is connected to the portion of the lifting body 22 near the rear of the range hood 1. The drive unit 70 can drive the lifting body 22 to move relative to the smoke collection body 21. By connecting the drive shaft of the drive unit 70 to the portion of the lifting body 22 near the rear of the range hood 1, space can be freed up on the front side of the range hood 1, thereby allowing the range hood 1 to have a larger air intake area.

[0033] In some embodiments, combined with Figure 3 When the range hood 1 is in the open state, in the arrangement direction of the frame 10 and the smoke collection assembly 20, the portion of the oil cup 30 near the front of the range hood 1 is closer to the smoke collection assembly 20 than the portion of the oil cup 30 near the rear of the range hood 1. By setting the portion of the oil cup 30 near the front of the range hood 1 closer to the smoke collection assembly 20 when the range hood 1 is open, the technical problem that the gap between the portion of the oil cup 30 near the front of the range hood 1 and the smoke collection assembly 20 is larger than the gap between the portion of the oil cup 30 near the rear of the range hood 1 and the smoke collection assembly 20 due to uneven driving force when the range hood 1 is closed can be compensated for. This improves the technical problem of uneven gap between the oil cup 30 and the smoke collection assembly 20 and also helps to improve the aesthetics of the range hood 1 when it is closed.

[0034] Specifically, when the range hood 1 is in the open state, that is, when the lifting body 22 is extended relative to the smoke collecting body 21, the shortest distance between the surface of the oil cup 30 near the smoke collecting assembly 20 and the portion of the smoke collecting assembly 20 near the rear of the range hood 1 is greater than the shortest distance between the surface of the oil cup 30 near the smoke collecting assembly 20 and the portion of the smoke collecting assembly 20 near the front of the range hood 1. In this way, when the range hood 1 is in the open state, the gap between the portion of the oil cup 30 near the rear of the range hood 1 and the smoke collecting assembly 20 is greater than the gap between the portion of the oil cup 30 near the front of the range hood 1 and the smoke collecting assembly 20. Thus, after the range hood 1 is turned off, that is, after the lifting body 22 is housed in the smoke collection body 21, since the drive device 70 is connected to the portion of the lifting body 22 near the rear of the range hood 1, the driving force on the portion of the lifting body 22 near the rear of the range hood 1 is greater than the driving force on the portion of the lifting body 22 near the front of the range hood 1 during the process of the lifting body 22 being housed in the smoke collection body 21. Therefore, the portion of the lifting body 22 near the rear of the range hood 1 will rise a greater distance than the portion near the front of the range hood 1. The oil cup 30 is installed on the lifting body 22, and the portion of the oil cup 30 near the rear of the range hood 1 will also rise a greater distance than the portion near the front of the range hood 1. When the range hood 1 is closed, the portion of the grease cup 30 near the rear of the range hood 1 rises a greater distance than the portion near the front of the range hood 1. This compensates for the larger gap between the portion of the grease cup 30 near the rear of the range hood 1 and the smoke collection assembly 20, resulting in a more uniform gap between the grease cup 30 and the smoke collection assembly 20 when the range hood 1 is closed. Optionally, the distance between the grease cup 30 and the smoke collection assembly 20 can refer to the distance between the grease cup 30 and the lower end face of the smoke collection body 21. In other words, when the range hood 1 is open, the rear position of the grease cup 30 is relatively low, and the front position is relatively high, thus compensating for the issue of the rear being higher and the front lower when the range hood 1 is closed, making the gap between the grease cup 30 and the smoke collection assembly 20 as equal as possible.

[0035] In some embodiments, combined with Figure 1 and Figure 3The oil cup 30 includes a main body 31 and side plates 32. The main body 31 is bent to form a space for accommodating droplets. The side plates 32 are located at both ends of the main body 31, closing the space formed by the main body 31. The main body 31 and the side plates 32 together form an open accommodating space facing the smoke collection assembly 20, allowing droplets generated by the smoke collection assembly 20 to enter the oil cup 30 through the opening. The main body 31 of the oil cup 30 forms the front and rear sides of the oil cup 30. On the one hand, the front side of the oil cup 30 does not interfere excessively with the smoke collection assembly 20, and the distance between the front side of the oil cup 30 and the smoke collection assembly 20 is not limited. On the other hand, the rear side of the oil cup 30 is obscured, preventing the user from directly observing it, and the distance between the rear side of the oil cup 30 and the smoke collection assembly 20 is also not specifically limited. On the other hand, since the main board 31 has sufficient length, the technical problems caused by the uneven driving force of the aforementioned drive device 70 are almost negligible on the front and rear sides of the oil cup 30. The technical problems caused by the aforementioned uneven driving force are mainly concentrated on the two side plates 32 of the oil cup 30. By setting the distance between the end face of the side plate 32 with the opening and the smoke collection assembly 20 in the direction from the rear to the front of the range hood 1 when the range hood 1 is in the open state, the gap between the oil cup 30 and the smoke collection assembly 20 can be made more uniform in the aforementioned manner when the range hood 1 is closed.

[0036] In some embodiments, when the range hood 1 is in the open state, the distance between the portion of the oil cup 30 near the rear side of the range hood 1 and the smoke collection body 21 is 1-2 mm more than the distance between the portion of the oil cup 30 near the front side of the range hood 1 and the smoke collection body 21, for example, 1.3 mm, 1.5 mm or 1.8 mm.

[0037] In some embodiments, combined with Figures 3 to 5 The range hood 1 also includes a mounting bracket 40, which is fixedly connected to the smoke collection assembly 20. The oil cup 30 is detachably connected to the mounting bracket 40. The mounting bracket 40 allows the oil cup 30 to be installed. The detachable connection of the oil cup 30 allows the user to disassemble the oil cup 30 for cleaning and also facilitates the packaging of the range hood 1. In the aforementioned embodiment, the portion of the oil cup 30 at the rear of the range hood 1 that is lower than the portion at the front of the range hood 1 can be achieved in various ways. Two specific implementation methods are given below.

[0038] In some embodiments, the mounting bracket 40 includes a body portion 41 and a mounting portion 42 disposed on the side of the body portion 41 near the smoke collection assembly 20. The portion of the mounting portion 42 near the rear side of the range hood 1 protrudes from the body portion 41 at a greater height than the portion of the mounting portion 42 near the front side of the range hood 1 protrudes from the body portion 41. In related technologies, during the mold-making process of the range hood 1, the lower end of the smoke collection assembly 20 is generally flat, and the upper end of the oil cup 30 is also generally flat. In this case, by making the above-described modification to the structure of the mounting bracket 40, after installation, the portion of the body portion 41 near the rear side of the range hood 1 can be lower than the portion of the body portion 41 near the front side of the range hood 1. Since the oil cup 30 is mounted on the body portion 41, the portion of the oil cup 30 at the rear side of the range hood 1 in the aforementioned embodiment can be lower than the portion of the oil cup 30 at the front side of the range hood 1. The tilting of the oil cup 30 can be achieved simply by modifying the structure of the mounting bracket 40, without changing the manufacturing processes of the smoke collection assembly 20 and the oil cup 30, which helps to reduce costs.

[0039] In some embodiments, the mounting bracket 40 is provided with a mounting groove 43, which has an opening facing the front of the range hood 1. The oil cup 30 is installed into the mounting groove 43 through the opening. The portion of the bottom of the mounting groove 43 near the rear of the range hood 1 is further away from the smoke collection assembly 20 than the portion of the bottom of the mounting groove 43 near the front of the range hood 1. By making the above-mentioned modifications to the structure of the mounting bracket 40, the oil cup 30 is installed at an angle when it enters the mounting groove 43. The angle of the mounting groove 43 allows the oil cup 30 to be tilted at both the front and rear of the range hood 1 as described in the previous embodiments. The tilting of the oil cup 30 can be achieved simply by modifying the structure of the mounting groove 43, without changing the manufacturing processes of the smoke collection assembly 20 and the oil cup 30, which helps to reduce costs.

[0040] In some embodiments, combined with Figures 6 to 8 The lifting body 22 needs to be housed within the smoke collection body 21 via lifting. To reduce interference, a gap exists between the lifting body 22 and the smoke collection body 21. However, this gap allows fumes to enter through it, causing condensation and oil droplets that are extremely difficult to clean. Furthermore, the gap can cause oil droplets inside the smoke collection assembly 20 to drip out through it. Since the gap is located at the edge of the assembly, the oil cup 30 cannot effectively collect the droplets, resulting in oil droplets falling outside the range hood 1. To address this issue, this application provides a sealing element 50 installed inside the smoke collection body 21 on the lifting body 22. This sealing element 50 seals the gap. By sealing the gap, fumes are prevented from entering the smoke collection assembly 20, and oil droplets inside the assembly are prevented from dripping out through the gap.

[0041] In some embodiments, the smoke collection body 21 is sleeved outside at least a portion of the lifting body 22. The seal 50 has an assembly portion 51 and a sealing portion 52. The assembly portion 51 is installed on the portion of the lifting body 22 located inside the smoke collection body 21. In the direction of the assembly portion 51 toward the smoke collection body 21, the sealing portion 52 extends obliquely from the assembly portion 51 toward a direction away from the frame 10. The oblique arrangement of the sealing portion 52 allows oil droplets to be smoothly guided to other locations inside the smoke collection assembly 20 when they fall onto the sealing portion 52, and then drip into the oil cup 30. This reduces the time oil droplets remain on the sealing portion 52, thereby further reducing the amount of oil droplets falling from the moving gap.

[0042] In some embodiments, combined with Figure 7 The smoke collection body 21 has a bent portion 60, which includes an installation section 61, an extension section 63, and a connecting section 62 connecting the installation section 61 and the extension section 63. The extension section 63 is closer to the interior of the smoke collection assembly 20 than the installation section 61, and the distance between the sealing part 52 and the installation section 61 is smaller than the distance between the extension section 63 and the installation section 61. The smoke collection body 21 has a front plate and a rear plate spaced apart, and the bent portion 60 is located at the end of the rear plate away from the frame 10. The installation section 61 of the bent portion 60 is connected to the rear plate. In this way, the bent portion 60 can form a space for accommodating oil droplets dripping from the sealing part 52, and the installation section 61, the connecting end, and the extension section 63 can prevent oil droplets from leaking from the moving gap. Furthermore, by setting the distance between the sealing part 52 and the installation section 61 to be smaller than the distance between the extension section 63 and the installation section 61, the leakage of oil droplets can be further reduced, reducing the oil droplet leakage problem that may be caused by the deformation of the seal 50. Optionally, the distance between the end of the sealing portion 52 near the mounting section 61 and the extension section 63 (combined) Figure 7 The distance L in the figure is greater than or equal to 3mm. For example, 3mm, 4mm or 5mm. Optionally, the distance between the orthographic projection of the end of the sealing part 52 near the connecting section 62 on the extension section 63 and the end of the extension section 63 near the frame 10 is between 0-2mm, for example 0.5mm, 1mm or 1.8mm.

[0043] In some embodiments, the extension 63 may also be provided with an oil drain, and an oil guide portion may be provided at the oil drain extending toward the interior of the smoke collection assembly 20, thereby guiding the oil droplets remaining in the bend 60 to the oil cup 30. Optionally, in order to reduce interference between the oil guide portion and the lifting body 22, the oil guide portion may be provided in the portion of the lifting body 22 with a recessed structure. For example, the lifting body 22 is slidably connected to the smoke collection body 21, the smoke collection body 21 is provided with a slide rail 81, and the lifting body 22 is recessed with a sliding portion 82 that cooperates with the slide rail 81. The oil guide portion may be correspondingly provided with the recessed sliding portion 82.

[0044] In some embodiments, combined with Figure 8 and Figure 9 The drive device 70 includes a first mounting portion 71 and a second mounting portion 72. The first mounting portion 71 cooperates with the smoke collection body 21, and the second mounting portion 72 cooperates with the lifting body 22. The first mounting portion 71 cooperates with the smoke collection body 21 through at least two different first mounting surfaces 711, and the second mounting portion 72 cooperates with the lifting body 22 through at least two different second mounting surfaces 721. Cooperating with the smoke collection body 21 through two different first mounting surfaces 711 further restricts the degrees of freedom of the drive device 70, thereby increasing the installation stability of the drive device 70. Cooperating with the smoke collection body 21 through two different second mounting surfaces 721 further restricts the degrees of freedom of the drive device 70, thereby increasing the installation stability of the drive device 70. Optionally, the two different first mounting surfaces 711 can be arranged in parallel, and the different first mounting surfaces 711 can be installed and cooperated with different positions of the smoke collection body 21. For example, one of the mounting surfaces can be cooperated with a high-strength crossbeam of the smoke collection body 21, thereby further increasing the installation stability. Optionally, the two different second mounting surfaces 721 can be set vertically to further restrict the freedom of installation.

[0045] In some embodiments, combined with Figure 10 The smoke collecting body 21 is equipped with a slide rail 81, and the lifting body 22 is equipped with a sliding part 82. The sliding part 82 cooperates with the slide rail 81 to realize the movable connection between the lifting body 22 and the smoke collecting body 21. Among them, the end of the slide rail 81 near the frame 10 is provided with a buffer pad 83 facing the sliding part 82. By setting the buffer pad 83, the impact of the slide rail 81 on the sliding part 82 can be buffered during the closing process of the smoke machine 1, thereby reducing the noise generated during the closing process of the smoke machine 1.

[0046] The above are merely embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
