Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and in particular to a range hood with a sliding cover. Background Technology

[0002] Compared to top-mounted range hoods, side-mounted range hoods have advantages such as smaller footprint, easier cleaning, and more aesthetically pleasing design, making them widely used in home environments. However, as individual users place higher demands on the aesthetics and size of range hoods, many side-mounted range hoods have further reduced their size. This means their intake duct can only handle the amount of smoke from light cooking, leading to smoke leakage during more intense cooking. To address this, some side-mounted range hoods have adopted an openable cover design to widen the intake duct when smoke volume is excessive, achieving stronger smoke extraction. However, the covers of side-mounted range hoods are often made of stainless steel or tempered glass, making them relatively heavy and prone to accumulating grease during use. The joint between the cover and the body can also become stuck, making it difficult to open, especially for shorter users or those with weaker limbs. This significantly impacts the user experience.

[0027] Detailed Implementation

[0028] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Please see Figures 1-5 This embodiment discloses a range hood with a sliding cover, comprising:

[0030] The internal housing 1 is equipped with the fan F. The control compartment 11 is mounted on the front of the housing 1, and guide slots 12 are set on both sides.

[0031] A smoke inlet 13 is provided below the control chamber 11, and several pulleys 14 are installed on both sides;

[0032] Based on a number of pulleys 14, the positioning post 21 of the cover plate 2 is slidably inserted into the guide groove 12;

[0033] A ratchet 22 is provided on the outer side of the positioning post 21, and a pawl 3 that is inserted into the guide groove 12 is installed on the side of the housing 1.

[0034] Pawl 3 locks the positioning pin 21.

[0035] In this embodiment, compared with the shortcomings of existing products that need to overcome the weight of the cover plate 2, the adhesive resistance and the static friction between the cover plate 2 and the box 1 when opening the cover, the pulley 14 is used to guide the cover plate 2 to slide, which transforms the static friction that needs to be overcome into sliding friction, greatly improving the user experience.

[0036] As an optional implementation, the side of the housing 1 is provided with an arc-shaped track 4 and a rotating handle 5, and the end of the rotating handle 5 is equipped with a pawl 3.

[0037] As an optional implementation, when the rotating handle 5 is rotated to the upper end of the rotating arc track 4, the front end of the pawl 3 is placed into the guide groove 12, locking the positioning pin 21.

[0038] As an optional implementation, when the rotating handle 5 is rotated to the lower end of the rotating arc track 4, the front end of the pawl 3 disengages from the guide groove 12 and releases the positioning pin 21.

[0039] As an alternative implementation, the pawl 3 rotates unidirectionally relative to the end of the rotating handle 5.

[0040] As an optional implementation, the pawl 3 slides on the positioning post 21 of the cover plate 2 and rotates unidirectionally relative to the end of the rotating handle 5.

[0041] As an optional implementation, the pawl 3 is fixed relative to the end of the rotating handle 5 when the positioning post 21 of the cover plate 2 slides down, thus locking the cover plate 2.

[0042] Here, the rotating handle 5 is used to adjust the position of the pawl 3. When the pawl 3 is placed in the guide groove 12, the positioning post 21 of the cover plate 2 is locked, ensuring that the cover plate 2 can only slide upward and not slide downward.

[0043] Furthermore, when it is necessary to reset the cover plate 2, the pawl 3 is removed from the guide groove 12 by turning the rotating handle 5, and it is disengaged from the positioning post 21, so that the cover plate 2 can slide down freely to reset.

[0044] As an optional implementation, the extreme position of the bottom sliding of the cover plate 2 is not higher than the upper edge of the smoke inlet 13.

[0045] Here, the bottom limit of the cover plate 2 is not higher than the upper edge of the smoke inlet hole 13 to ensure that no loosening accident occurs.

[0046] As an alternative implementation, a flue 23 is provided in the middle of the cover plate 2.

[0047] Here, the smoke inlet 23 of the cover plate 2 is used to extract oil fumes when the amount of oil fumes is small, while when the amount of oil fumes is large, such as when stir-frying, the cover plate 2 is slid up to open the smoke inlet 13 to achieve high-efficiency extraction of oil fumes.

[0048] As an optional implementation, the top of the fan F is equipped with a flue 6.

[0049] Compared with the prior art, this embodiment has the following beneficial effects:

[0050] In this embodiment, the cover slides relative to the box based on the pulley, and is locked by the pawl after sliding up, so it does not slide down. The opening process is simple and effortless, and there is no difficulty in use due to oil stains sticking to it, resulting in a good user experience.
