Description

Technical Field

[0001] This utility model relates to the field of home appliance technology, and in particular to a range hood with side panels. Background Technology

[0002] A range hood is an appliance that collects and exhausts cooking fumes from indoor spaces. It mainly consists of a housing and a fan. The housing has an air inlet. When the fan is working, it creates a negative pressure inside the housing, drawing the cooking fumes into the housing through the air inlet, thus collecting and exhausting the fumes.

[0003] Some existing range hoods also feature a smoke guide plate. When the range hood is working, the smoke guide plate opens the air inlet, allowing cooking fumes to enter. When the range hood is not working, the smoke guide plate covers the air inlet, improving its appearance and preventing dust and foreign objects from entering. To prevent cooking fumes from escaping from the sides of the smoke guide plate, some existing range hoods have flaps on the left and right sides. These flaps, the smoke guide plate, and the outer casing abut or connect to each other, forming a smoke collection chamber.

[0004] The drawbacks of existing range hoods with flip-up flaps include: the moving parts that control the state of the smoke guide plate are usually located on or inside the outer casing. During the collection and exhaust process, the fumes pass through the moving parts, and the fumes will condense into oil stains on the moving parts. The oil stains will cause pollution and corrosion to the moving parts, shortening their service life. Utility Model Content

[0005] The purpose of this invention is to propose a range hood with side panels, which solves the problem that oil stains in existing range hoods can cause pollution and corrosion to moving parts, and extends the service life of the moving parts.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., 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, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium.

[0034] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0035] This embodiment discloses a range hood with side panels, such as... Figures 1 to 3 As shown, the range hood includes a housing 1, an air guide plate assembly 2, a side baffle assembly, and a motion assembly. The air guide plate assembly 2 is connected to the housing 1 via a hinge. The housing 1 has a smoke inlet 11, and the motion assembly can drive the air guide plate assembly 2 to block or open the smoke inlet 11.

[0036] The side baffle assembly includes an inner baffle and an outer baffle spaced apart, forming a fume protection space between them. The moving components are positioned within this fume protection space. While they cannot completely isolate the fumes from the moving components, they significantly reduce the amount of contact between the fumes and the moving components, resulting in a noticeable protective effect. Specifically, the inner baffle is closer to the center of the fume inlet 11 and primarily serves to block the fumes; the outer baffle is closer to the outer wall of the outer casing 1 and primarily serves a decorative function.

[0037] The inner baffle prevents oil fumes from contacting the moving parts, reducing the condensation of oil on these parts and solving the problem of oil contamination and corrosion of moving components in existing range hoods. This extends the lifespan of the moving parts, improves the overall safety of the range hood, and provides a better user experience. The outer baffle conceals the moving parts, preventing them from protruding and enhancing the overall aesthetics of the range hood. Furthermore, the side baffles prevent oil fumes from escaping, improving smoke collection and resulting in better smoke extraction.

[0038] like Figure 3 As shown, the inner baffle includes a first inner baffle 31 and a second inner baffle 32. One of the first inner baffle 31 and the second inner baffle 32 is mounted on the outer casing 1, and the other of the first inner baffle 31 and the second inner baffle 32 is mounted on the air guide plate assembly 2. When the air guide plate assembly 2 opens and closes, the first inner baffle 31 and the second inner baffle 32 can move relative to each other to avoid affecting the normal opening and closing of the air guide plate assembly 2.

[0039] The outer baffle includes a first outer baffle 41 and a second outer baffle 42. One of the first outer baffle 41 and the second outer baffle 42 is mounted on the outer casing 1, and the other of the first outer baffle 41 and the second outer baffle 42 is mounted on the air guide plate assembly 2. When the air guide plate assembly 2 is opened and closed, the first outer baffle 41 and the second outer baffle 42 can move relative to each other to avoid affecting the normal opening and closing of the air guide plate assembly 2.

[0040] In this embodiment, an air inlet assembly is provided on the outer casing 1, and a smoke inlet 11 is opened on the air inlet assembly. One of the first inner baffle 31 and the second inner baffle 32 is fixed on the air inlet assembly, and one of the first outer baffle 41 and the second outer baffle 42 is also fixed on the air inlet assembly, which makes it easier to install the moving components and makes the air guide plate assembly 2 open and close more smoothly.

[0041] To improve processing efficiency and facilitate the installation of moving components, the first inner baffle 31 is parallel to the first outer baffle 41, and the second inner baffle 32 is parallel to the second outer baffle 42. The fume protection space has a more regular shape and higher space utilization, allowing moving components of various models and sizes to be installed in the fume protection space between the inner and outer baffles.

[0042] To prevent collisions between the first inner baffle 31 and the second inner baffle 32 during relative movement, in this embodiment, the first inner baffle 31 and the second inner baffle 32 are staggered. Correspondingly, the first outer baffle 41 and the second outer baffle 42 are also staggered to prevent collisions between them during relative movement.

[0043] After misalignment, an inner baffle air passage gap 33 is formed between the first inner baffle 31 and the second inner baffle 32, and an outer baffle air passage gap 43 is formed between the first outer baffle 41 and the second outer baffle 42. The inner baffle air passage gap 33 and the outer baffle air passage gap 43 can connect the outer space of the side baffle assembly to the smoke collection channel inside the outer shell 1. Under negative pressure, oil fumes located outside the range hood may enter the outer shell 1 through the outer baffle air passage gap 43 and the inner baffle air passage gap 33, thereby improving the oil fume collection effect.

[0044] During the process of absorbing cooking fumes, more fumes will enter the outer casing 1 through the smoke inlet 11. The amount of fumes entering through the air passage gaps 33 and 43 of the inner and outer baffles is relatively small. The amount of oil stains condensed on the moving parts by these fumes is small and its impact can be ignored.

[0045] The widths of the air passage gaps 33 and 43 of the inner and outer baffles are not limited, as long as they can prevent the side baffles from colliding with each other when moving and facilitate the passage of oil fumes. In this embodiment, the width of the air passage gap 43 of the outer baffle is in the range of 5mm ± 2mm; and / or, the width of the air passage gap 33 of the inner baffle is in the range of 3mm ± 2mm.

[0046] In order to increase the capacity of the fume protection space, in this embodiment, the range hood includes two sets of side baffle assemblies, which are respectively set at the left and right ends of the range hood. Each set of side baffle assemblies can be equipped with a moving component in the fume protection space, and the moving components can be different.

[0047] The specific shape and composition of the moving components are not limited, as long as they can meet the movement requirements of components such as the air guide plate assembly 2 on the range hood. In this embodiment, for example... Figures 4 to 9 As shown, the motion component includes a drive motor 51 and a motor bracket 52 connected to each other. The output end of the drive motor 51 is hinged to the air guide plate assembly 2. When the output end of the drive motor 51 extends or retracts, it can drive the air guide plate assembly 2 to swing relative to the outer shell 1.

[0048] The drive motor 51 is connected to the top plate of the outer casing 1 via the motor bracket 52, resulting in a more stable installation structure. The drive motor 51 is located between the first inner baffle 31 and the first outer baffle 41, both of which are fixed to the air guide plate assembly 2. This allows the drive motor 51 to apply force more directly to the air guide plate assembly 2, resulting in smoother opening and closing of the air guide plate assembly 2.

[0049] Based on the above structure, the motion assembly also includes a geared motor 61, a lower hinge 62, and a middle hinge 63. The air guide plate assembly 2 includes two air guide plates, with the middle hinge 63 connecting the two air guide plates, allowing the two air guide plates to rotate relative to each other around the middle hinge 63. Preferably, the lower hinge 62 is a four-bar linkage structure, and the output end of the geared motor 61 is connected to the lower air guide plate via the lower hinge 62.

[0050] The geared motor 61 is located between the first inner baffle 31 and the first outer baffle 41 and is fixedly connected to the air guide plate assembly 2. During the extension and retraction of the output end of the geared motor 61, the lower hinge 62 can push the air guide plate to swing around the central hinge 63, thereby opening and closing the smoke inlet 11.

[0051] To improve the stability of the movement, in this embodiment, the motion assembly further includes a slide rail seat 53, a slide rail 54, a connecting rod 55, and a lower rotating shaft bracket 56 fixedly connected to the outer casing 1. The lower end of the air inlet assembly is hinged to the lower rotating shaft bracket 56, which is fixed to the inner bottom of the outer casing 1. The slide rail 54 is fixed to the air guide plate assembly 2 via the slide rail seat 53. One end of the connecting rod 55 is connected to the slide rail 54, and the other end is hinged to the air inlet assembly. When the air guide plate assembly 2 opens and closes, the connecting rod 55 pulls the air inlet assembly to rotate around the rotation axis on the lower rotating shaft bracket 56 to open and close, preventing the movement from getting stuck.

[0052] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
