Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a range hood. Background Art

[0002] A range hood is an electrical appliance widely used in the kitchen for discharging the oil fume generated during cooking. The range hood usually includes a smoke collecting hood and a flap. An air inlet is formed on the smoke collecting hood. When the range hood is not working, the flap is in a closed state that blocks the air inlet; when the range hood is working, the flap is in an open state that turns outward and opens the air inlet. At this time, the flap can play the role of gathering the fume.

[0003] For a double-flap structure, the upper flap and the lower flap are driven by a driving mechanism. The upper flap can turn outward relative to the smoke collecting hood by a certain angle, and the lower flap can further turn outward relative to the upper flap. Both the upper flap and the lower flap are connected to the driving mechanism. However, due to the error in their movement trajectories, the movement of the lower flap is unstable during the movement process, and problems such as interference with the upper flap or too large a gap between the lower flap and the upper flap are likely to occur.

[0004] In addition, at present, most range hoods are provided with atmosphere lights and lighting lights on the flap. For a double-flap structure, since the lower flap can move relative to the upper flap, it is not convenient for wiring, and it is difficult to set the atmosphere lights and lighting lights.

[0043] The technical solution of the present utility model will be further described below with reference to the accompanying drawings and through specific embodiments.

[0044] See Figures 1 to 11 , this embodiment provides a range hood, which includes a smoke collecting assembly 10, a flap assembly 20 and a duct assembly 30. The smoke collecting assembly 10 includes a smoke collecting hood 11, and the smoke collecting hood 11 has a smoke collecting cavity with an opening at the front; the flap assembly 20 is movably arranged on the smoke collecting hood 11 to open or close the smoke collecting cavity; the duct assembly 30 includes a housing and a fan, a smoke guiding channel communicating with the smoke collecting cavity is formed inside the housing, and the fan is used for sucking oil fumes and discharging them through the smoke guiding channel.

[0045] The flap assembly 20 includes a first flap 21 and a second flap 22. The first flap 21 is movably connected to the smoke collecting hood 11 and can move between a closed position and an open position. The second flap 22 is movably connected to the first flap 21, and the second flap 22 can be turned outwards relative to the first flap 21 by a certain angle. After the second flap 22 is turned outwards relative to the first flap 21, an included angle exists between the second flap 22 and the first flap 21. When the second flap 22 is not turned relative to the first flap 21, the second flap 22 and the first flap 21 are coplanar.

[0046] The first flap 21 can open or close at least part of the smoke collecting cavity, and the second flap 22 can open or close at least part of the smoke collecting cavity. When the first flap 21 is in the closed position and the second flap 22 is not turned relative to the first flap 21, the first flap 21 and the second flap 22 jointly close the smoke collecting cavity. The sizes of the first flap 21 and the second flap 22 can be set according to actual needs.

[0047] In this embodiment, the second flap 22 is rotatably connected to the first flap 21. Specifically, the flap assembly 20 further includes a rotating shaft assembly 23. The rotating shaft assembly 23 is disposed between the first flap 21 and the second flap 22. The rotating shaft assembly 23 includes a rotating shaft 231 and a rotating arm 232. The rotating shaft 231 is fixedly connected to the first flap 21, and an accommodating space 2301 is formed inside the rotating shaft 231; one end of the rotating arm 232 is nested in the rotating shaft 231 and can rotate around the axis of the rotating shaft 231, and the other end of the rotating arm 232 is fixedly connected to the second flap 22.

[0048] The rotating shaft 231 and the rotating arm 232 are connected by nesting, so as to connect the second flap 22 and the first flap 21, enabling the second flap 22 to rotate around the axis of the rotating shaft 231 relative to the first flap 21, which can ensure the stability of the movement of the second flap 22.

[0049] The range hood further includes a lamp assembly 40. The lamp assembly 40 includes an ambient light 41 and a lighting lamp 42. The ambient light 41 and the lighting lamp 42 are disposed in the accommodating space 2301. It is equivalent to integrating the lamp assembly 40 on the rotating shaft 231. Since the rotating shaft 231 is fixedly connected to the first flap 21, during the rotation of the second flap 22 relative to the first flap 21, the rotating shaft 231 is relatively fixed, thereby ensuring the stability of the lamp assembly 40. The rotating shaft 231 can also prevent the lamp assembly 40 from contacting oil fumes, water vapor, etc., playing a protective role for the lamp assembly 40, making full use of the space to realize the coexistence of the ambient light 41 and the lighting lamp 42 and facilitating wire routing.

[0050] Based on the front-back, left-right, and up-down directions of the smoke collecting hood 11, the axis of the rotating shaft 231 extends in the left-right direction. Both the first flap 21 and the second flap 22 can be flipped forward and upward to open the smoke collecting cavity, and flipped backward and downward to close the smoke collecting cavity.

[0051] The rotating arm 232 is nested and rotatably connected to the rotating shaft 231. It can be that lugs are provided on the rotating shaft 231, and the rotating arm 232 is connected to the lugs through a pin shaft. It can also be that mounting holes are provided on the rotating shaft 231, and part of the rotating arm 232 is inserted into the mounting holes to be rotatably connected to the rotating shaft 231.

[0052] In this embodiment, the rotating shaft 231 includes a shaft body 2311, an end cover 2312 and a first connecting frame 2313. The end cover 2312 has a step surface. The rotating arm 232 is sleeved on the end cover 2312. The end cover 2312 is inserted into the end of the shaft body 2311. The rotating arm 232 is located between the step surface and the end surface of the shaft body 2311. One end of the first connecting frame 2313 is fixedly connected to the end cover 2312, and the other end of the first connecting frame 2313 is fixedly connected to the first flap 21. The step surface and the end surface of the shaft body 2311 play a limiting role on the rotating arm 232, that is, the rotating arm 232 is nested between the shaft body 2311 and the end cover 2312. When installing, the rotating arm 232 is first sleeved on the end cover 2312, and then the end cover 2312 is inserted into the shaft body 2311.

[0053] The rotating arm 232 includes a sleeve 2321, a connecting portion 2322, and a second connecting frame 2323. The sleeve 2321 is nested in the rotating shaft 231. The connecting portion 2322 and the second connecting frame 2323 are spaced apart around the circumference of the sleeve 2321. The connecting portion 2322 is used to connect the driving mechanism. The second connecting frame 2323 is fixedly connected to the second flap 22. Specifically, the sleeve 2321 is sleeved on the end cover 2312, and the sleeve 2321 is located between the step surface and the end surface of the shaft body 2311. The second connecting frame 2323 and the second flap 22 can be fixed by a plurality of screws.

[0054] The driving mechanism can drive the rotating arm 232 to rotate around the axis of the rotating shaft 231. In an achievable embodiment, the driving mechanism includes a push rod motor, which is rotatably arranged on the first flap 21, and the push rod of the push rod motor is hinged with the adapter 2322. The push rod extends or retracts to drive the rotating arm 232 to rotate around the axis of the rotating shaft 231. The first flap 21 and the second flap 22 can be driven separately. For the first flap 21, the existing driving mechanism of a single flap structure can be adopted, which will not be described in detail here.

[0055] The shaft body 2311 has an accommodating space 2301 formed inside, and the end cap 2312 is provided with a lead groove 2302 communicating with the accommodating space 2301 and a lead hole 2303 communicating with the lead groove 2302, and the first connecting frame 2313 is provided with a threading groove 2304 communicating with the lead hole 2303. The lamp assembly 40 also includes a wire 47, and the lead groove 2302, the lead hole 2303 and the threading groove 2304 guide the wire 47, facilitate the routing and limit the position of the wire 47. The wire 47 can pass through the threading groove 2304 and then be connected to the electrical components on the first flap 21, for example, the wire 47 is connected to the button on the first flap 21.

[0056] The wire trough 2304 is located on the side where the first connecting bracket 2313 abuts against the first flap 21, and the first connecting bracket 2313 shields the wire 47 in the wire trough 2304. After being fixed between the first connecting bracket 2313 and the first flap 21, the wire 47 in the wire trough 2304 is shielded by the first connecting bracket 2313. While ensuring a clean appearance, the smooth installation of the wire 47 is achieved, meeting the safety regulation requirements.

[0057] The first connecting bracket 2313 is fixedly connected to the end cover 2312, which is convenient for installation and disassembly. Specifically, it can be fixed by multiple screws. The first connecting bracket 2313 and the first flap 21 can also be fixed by multiple screws. As Figure 5 and Figure 8 shown, a notch is provided on the outer peripheral surface of the shaft body 2311. The first connecting bracket 2313 is located at the notch, and the lead hole 2303 provided on the end cover 2312 is arranged opposite to the notch, which is convenient for aligning the wire trough 2304 on the first connecting bracket 2313 with the lead hole 2303 on the end cover 2312, and then locking the first connecting bracket 2313 and the end cover 2312 with screws. The two screws are distributed on both sides of the lead hole 2303, making the first connecting bracket 2313 and the end cover 2312 receive balanced forces.

[0058] During installation, the rotating arm 232 is sleeved on the end cover 2312, the end cover 2312 is inserted into the shaft body 2311, and the first connecting bracket 2313 is placed at the notch of the shaft body 2311, so that the lead hole 2303 is aligned with the wire trough 2304, and the screws lock the first connecting bracket 2313 and the end cover 2312, and the screws lock the first connecting bracket 2313 and the first flap 21.

[0059] There are two end covers 2312, first connecting brackets 2313 and rotating arms 232, which are distributed at both ends of the shaft body 2311. There are two end covers 2312, which are inserted into the left and right ends of the shaft body 2311. There are two first connecting brackets 2313, and each first connecting bracket 2313 is connected to one end cover 2312. There are two rotating arms 232, and each rotating arm 232 is sleeved on one end cover 2312, making the second flap 22 receive balanced forces.

[0060] The lamp assembly 40 includes an ambient light 41 and a lighting lamp 42. The ambient light 41 includes color - changeable LED lamp beads and can emit ambient light. The lighting lamp 42 includes lighting LED lamp beads and can illuminate the cooking area.

[0061] The ambient light 41 and the lighting lamp 42 emit light towards the opposite sides of the rotating shaft 231. The light emitted by the ambient light 41 is directed towards the lower end surface of the first flap 21. The gap between the rotating shaft 231 and the lower end surface of the first flap 21 is not on the main movement path of the oil fume, so that most of the oil fume and steam can be avoided, and the phenomenon that the oil fume blocks the light can be improved.

[0062] The light emitted by the illuminating lamp 42 is downward. After the first flap 21 is in the open position relative to the smoke collecting hood 11 and the second flap 22 is turned outwards relative to the first flap 21, the second flap 22 shields the illuminating lamp 42 from the outside. As Figure 11 shown, the ambient light lamp 41 emits ambient light, and the ambient light irradiates the lower end surface of the first flap 21. The light emitted by the illuminating lamp 42 shines completely downward on the cooking area, giving the user a better experience. At the same time, standing at the position of the cook, the illuminating lamp 42 cannot be seen, which not only solves the problem of insufficient illumination in the cooking area, but also solves the problem of dazzling illumination light.

[0063] Exemplarily, the lamp assembly 40 further includes a lamp board 43. The ambient light lamp 41 is disposed on one side of the lamp board 43, and the illuminating lamp 42 is disposed on the other side of the lamp board 43. The ambient light lamp 41 and the illuminating lamp 42 share one lamp board 43, reducing the number of components and the space occupied.

[0064] Card slots communicating with the accommodation space 2301 are provided on both opposite sides of the rotating shaft 231. The lamp assembly 40 further includes an ambient light cover 44 and an illuminating lamp cover 45. The ambient light cover 44 is disposed in one card slot and is directly opposite to the ambient light lamp 41, and the illuminating lamp cover 45 is disposed in the other card slot and is directly opposite to the illuminating lamp 42. The ambient light lamp 41 emits ambient light through the ambient light cover 44, and the illuminating lamp 42 irradiates the cooking area through the illuminating lamp cover 45. Among them, the ambient light cover 44 is a light-transmitting plate with a frosted surface, making the light emitted by the ambient light lamp 41 more uniform and the internal lamp beads cannot be directly seen.

[0065] The lamp assembly 40 further includes a lamp bracket 46. The lamp bracket 46 is disposed in the accommodation space 2301. A plurality of positioning slots are provided on the lamp bracket 46. The lamp board 43, the ambient light cover 44 and the illuminating lamp cover 45 are all inserted into the positioning slots. The lamp bracket 46 plays a supporting role for the lamp board 43, the ambient light cover 44 and the illuminating lamp cover 45. During installation, first insert the ambient light cover 44 and the illuminating lamp cover 45 into the shaft body 2311 respectively and snap them into the corresponding card slots. Then insert the lamp bracket 46 into the shaft body 2311. During the insertion process, align the ambient light cover 44 and the illuminating lamp cover 45 with the positioning slots on the lamp bracket 46 and insert them. Then insert the lamp board 43 into the corresponding positioning slots, and then install the end caps 2312 at both ends.

[0066] As Figure 11As shown in the figure, the first flap 21 includes a plate body and a first glass disposed on the outer surface of the plate body. The atmosphere lamp cover 44 is located below the first glass. The atmosphere lamp 41 emits atmosphere light through the atmosphere lamp cover 44, and the atmosphere light irradiates the first glass to form an atmosphere light band. The lighting lamp cover 45 is disposed on the side of the rotating shaft 231 away from the first flap 21. The light emitted by the lighting lamp 42 is downward. After the first flap 21 is in the open position relative to the smoke exhaust hood 11 and the second flap 22 is flipped outward relative to the first flap 21, the second flap 22 shields the lighting lamp 42 from the outside, so that the light emitted by the lighting lamp 42 completely irradiates the cooking area through the lighting lamp cover 45. The user can see the light but not the lamp, which gives the user a better experience. It not only solves the problem of insufficient illuminance in the cooking area, but also solves the problem of dazzling lighting.
