Description

Technical Field

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

[0002] The distance between the range hood's suction vent and the stovetop affects the smoke extraction effect. In the current technology, most range hoods are not height-adjustable after installation, and a few lift-type range hoods have increased costs due to the addition of a lift motor.

[0003] Secondly, after installation, the range hood often cannot be completely flush with the bottom of the cabinet, which greatly reduces the product's aesthetic appeal.

[0004] In addition, the installation method without cabinets often requires the purchase of an extended duct cover to extend the height of the duct cover to the ceiling for an aesthetic effect. However, the extended duct cover is a custom-made product, so its color will differ from the range hood. At the same time, the stability of the installation needs to be improved. Summary of the Invention

[0005] This utility model aims to at least partially solve one of the problems existing in the existing related technologies. To this end, this utility model proposes a range hood with a simple structure.

The components of the embodiments of this utility model can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of the claimed invention.

[0030] Example:

[0031] like Figure 1 and 2 As shown, a range hood includes:

[0032] Inner box 1;

[0033] The outer casing 2 is movably fitted onto the outside of the inner casing 1, and a smoke collection hood 3 is provided at the bottom of the outer casing 2.

[0034] The slide rail assembly 4 allows the outer housing 2 to slide up and down along the inner housing 1.

[0035] Limiting component 5 is installed on inner box 1;

[0036] The limiting part 6 is provided on the side wall of the outer casing 2, and the limiting component 5 is connected to the limiting part 6 to limit the up and down sliding of the outer casing 2.

[0037] In this embodiment, the rear wall of the inner box 1 is fixedly mounted on a fixed wall. An outer box 2 is movably fitted onto the outside of the inner box 1. A smoke hood 3 is provided at the bottom of the outer box 2, and an air inlet is provided on the smoke hood 3, so that the air inlet communicates with the internal space of the inner box 1 after passing through the outer box 2. A slide rail assembly 4 is provided between the outer box 2 and the inner box 1. Under the action of external force, the outer box 2 slides up and down along the inner box 1 through the slide rail assembly 4. At the same time, the sliding of the outer box 2 drives the smoke hood 3. Synchronous sliding is achieved by providing a limiting part 6 on the side wall of the outer casing 2 and a limiting component 5 on the side wall of the inner casing 1 that cooperates with and connects to the limiting part 6. When the outer casing 2 slides up and down along the inner casing 1 to a suitable height position, the limiting component 5 and the limiting part 6 cooperate to limit the up and down sliding of the outer casing 2, thereby keeping the smoke hood 3 at the current height position. Its structure is simple, and by adjusting the height between the smoke inlet and the stove according to the actual oil fume concentration, it can meet the user's required smoke extraction effect.

[0038] More preferably, within the vertical sliding range, the sliding limit of the outer casing 2 shall not exceed the upper and lower ends of the inner casing 1, so that the outer casing 2 always encloses the inner casing 1 within it.

[0039] Furthermore, there are multiple limiting parts 6, which are arranged at intervals along the vertical direction on the side wall of the outer casing 2. The limiting components 5 are connected to the limiting parts 6 at different height positions to adjust the height of the outer casing 2.

[0040] Preferably, the limiting component 5 includes a mounting base 51, a telescopic ball 52, and a spring 53. A through hole is provided on the front side wall of the outer housing 2 to form a limiting part 6. The mounting base 51 is disposed on the front side wall of the inner housing 1 and defines a mounting hole with an open front end. The telescopic ball 52 and the spring 53 are respectively disposed in the mounting hole. The rear end of the spring 53 abuts against the closed end of the mounting hole, and its front end abuts against the rear end of the telescopic ball 52. Under the elastic force of the spring 53, the front end of the telescopic ball 52 extends forward out of the mounting hole and into the through hole to limit the sliding of the outer housing 2.

[0041] Specifically, it also includes screws, and protruding plates 55 are respectively provided at the left and right ends of the mounting base 51. Assembly holes 56 are provided on the protruding plates 55, and mating holes are provided on the front side wall of the inner box 1. Screws are used to connect the mating holes and the assembly holes 56 together.

[0042] Preferably, an opening is provided on the front side wall of the inner housing 1, and the rear end of the mounting base 51 passes through the opening.

[0043] Furthermore, a mounting groove 13 is recessed on the front side wall of the inner box 1, and the mounting seat 51 is disposed in the mounting groove 13.

[0044] In this embodiment, since there are multiple limiting parts 6, through holes are provided on the front side wall of the outer casing 2 to form the limiting parts 6. That is, multiple through holes are provided at intervals along the vertical direction on the front side wall of the outer casing 2, so that multiple limiting parts 6 are provided at intervals along the vertical direction on the side wall of the outer casing 2. In this way, there are multiple limiting parts 6 at different height positions. Under the action of external force, the outer casing 2 slides up and down along the inner casing 1 through the slide rail assembly 4. When the outer casing 2 slides up and down along the inner casing 1 to a suitable height position, the limiting assembly 5 cooperates with the limiting parts 6 at different height positions to limit the up and down sliding of the outer casing 2, so that the smoke hood 3 is kept at the current height position, and the height adjustment of the outer casing 2 can be completed, thus meeting the user's need for different installation heights.

[0045] In this embodiment, multiple limiting portions 6 are respectively provided on the left and right sides of the front sidewall of the outer casing 2, and mounting seats 51 are correspondingly provided on the left and right ends of the front sidewall of the inner casing 1. Each mounting seat 51 has a mounting hole with an open front end; that is, the front end of the mounting seat 51 is open, and its rear end is closed. One end of the spring 53 abuts against the closed end of the mounting hole, and the other end abuts against the rear end of the telescopic ball 52, thereby enabling the telescopic ball 52 to telescopically extend under the elastic force of the spring 53. Since at least a portion of the telescopic ball 52 is confined within the internal space of the mounting seat 51, the front end of the telescopic ball 52 is subject to the elastic force of the spring 53. Under the action of the spring 52, the spring 52 extends forward from the mounting hole and into the through hole. In this way, during the adjustment of the installation height of the smoke hood 3, after the height is adjusted, the front end of the compression ball 52 extends into the corresponding through hole. That is, the telescopic ball 52 and the corresponding limiting part 6 are connected together, thereby limiting the vertical sliding of the outer box 2 and keeping the smoke hood 3 at the current height position. Alternatively, the front end of the telescopic ball 52 applies pressure to the spring 53 under the action of external force, thereby disconnecting the front end of the telescopic ball 52 from the through hole and retracting it into the internal space of the mounting base 51, so that the outer box 2 slides up and down along the inner box 1 under the action of external force.

[0046] More preferably, a mounting groove 13 is recessed on the front side wall of the inner housing 1, and an opening is formed on the front side wall of the inner housing 1. This allows the opening to be located within the mounting groove 13. The rear end of the mounting base 51 passes through the opening from front to back until the protruding plates 55 on the left and right sides of the mounting base 51 abut against the front side wall of the inner housing 1. At the same time, the mounting base 51 is also confined within the mounting groove 13. Then, the screw passes through the mating hole and engages with the assembly hole 56 to connect together, thereby fixing the mounting base 51 on the inner housing 1, which can effectively improve the stability of the mounting base 51 assembly.

[0047] Furthermore, the slide rail assembly 4 includes a first slide rail 41 and a second slide rail, wherein the first slide rail 41 is respectively disposed on the outer side walls at the left and right ends of the inner box 1, and the second slide rail is correspondingly disposed on the inner side wall of the outer box 2, and the first slide rail 41 and the second slide rail are slidably connected together.

[0048] Specifically, it also includes a fan 7, which is installed inside the inner casing 1.

[0049] Specifically, an installation part 8 is provided at the rear end of the inner box 1, and the installation part 8 is connected to the fixed wall to install the inner box 1 on the fixed wall.

[0050] In this embodiment, first slide rails 41 are respectively provided on the outer side walls at both ends of the inner box 1, and second slide rails are correspondingly provided on the inner side walls at both ends of the outer box 2. The first slide rails 41 and the second slide rails are slidably connected together, thereby enabling the outer box 2 and the inner box 1 to slide together, which facilitates the user to slide the outer box 2 up and down. In addition, a fan 7 is provided in the internal space of the inner box 1. The fan 7 rotates to discharge the cooking fumes sequentially through the air inlet of the fume hood 3, the outer box 2, the inner box 1, and the fan 7. An installation part 8 is provided at the rear end of the inner box 1. The installation part 8 is connected to the fixed wall by screws, thereby fixing the inner box 1 to the wall, which facilitates the installation of the inner box 1.

[0051] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
