DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

Therefore, they cannot be understood as limitations on the present invention.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] In the prior art, the transmission structure for lifting and retracting the glass panel 2 of the range hood is generally divided into two ends, one end is the power end, and the other end is the mechanical driven end. Due to the uneven power distribution on both sides, the two sides of the glass panel 2 will move inconsistently and the glass on the driven end cannot be tightened.

[0040] In view of this, if Figure 1-5 As shown, the utility model provides a range hood, comprising:

[0041] A range hood casing 1, wherein the range hood casing 1 defines a smoke collecting chamber 10;

[0042] The glass panel 2 can be rotatably set on the front end surface of the range hood casing 1. When the range hood is not started, the glass panel 2 is set in contact with the front end surface of the range hood casing 1 to ensure the beautiful appearance of the range hood. When the range hood is working, the glass panel 2 of the utility model forms a smoke inlet channel between the range hood casing 1 after rotation. When the range hood stops working, the glass panel 2 returns to the state of being in contact with the front end surface of the range hood casing 1.

[0043] Correspondingly, in order to realize the lifting and recovery action of the glass panel 2, the range hood of the present invention is also provided with a transmission device, which includes an active part 4, and at least one driven part 5 is respectively provided on both sides of the active part 4. The driving end of the active part 4 is connected to the glass panel 2 to drive the glass panel 2 to rotate relative to the range hood housing 1, and the end of the driven part 5 is connected to the glass panel 2 to limit the rotation path of the glass panel 2, that is, in the utility model, the rotation center of the glass panel 2 is adjusted from the active part 4 to the driven part 5.

[0044] When only two driven parts 5 are provided, considering that the glass panel 2 can be opened from any direction to form a smoke inlet channel, the two driven parts 5 are respectively provided at both ends of any side of the glass panel 2 , and the active part 4 is provided between the two driven parts 5 .

[0045] At this time, the active part 5 only plays the role of providing rotational power, and the driven part 5, as the rotation center, plays a guiding role in the lifting and recovery process of the glass panel 2, thereby avoiding the problem of inconsistent movement on both sides of the glass panel 2 due to inconsistent power on both sides of the glass panel 2 and the glass panel 2 cannot be tightened.

[0046] On the other hand, in the present invention, since at least two driven parts 5 are provided, the weight of the glass panel 2 is dispersed, so that the driven parts 5 can be made of lighter and thinner materials to reduce production costs.

[0047] When three or more follower parts 5 are provided, two follower parts 5 still need to be provided at the two ends of any side of the glass panel 2 to ensure the consistency of displacement on both sides of the glass panel 2 and avoid the problem that the glass panel 2 cannot be tightened. The remaining follower parts 5 can be provided between the follower parts 5 at both ends to further increase the stability of the glass panel 2 during the lifting and recovery process.

[0048] If active parts 4 are provided at both ends of any side of the glass panel 2, there may still be deviations due to the inconsistency of the speed, force and working time of the active parts 4 at both ends. If only one active part 4 is provided in the middle of the glass panel 2, on the one hand, since the range hood casing 1 is connected to the smoke outlet channel 3 here, the fixing of the active part 4 is more complicated. On the other hand, at this time, both ends of the glass panel 2 are free ends, which is not conducive to the positioning of the glass panel 2 during the lifting and recovery process.

[0049] Therefore, the utility model arranges two driven parts 4 at the two ends of any side of the glass panel 2 to limit its rotation path, and arranges the active part 4 between the two driven parts 5 to drive the glass panel 2 to rotate, which can not only ensure the positioning of the glass panel 2 during the lifting and recovery process to avoid it from being unable to be tightened, but also reduce the production cost of the driven part 5.

[0050] Specifically, to ensure that the active part 4 is only used to provide rotational power for the glass panel 2, the active part 4 in the utility model includes a power unit 41, a first swing arm 42 and a second swing arm 43, wherein the power unit 41 is arranged in the smoke collecting chamber 10, and is used to provide power for the glass panel 2 to rotate, one end of the first swing arm 42 is hinged to the power unit 41, and the other end is hinged to the second swing arm 43, and the other end of the second swing arm 43 is fitted and connected to the glass panel 2.

[0051] When the power unit 41 is working, since the first swing arm 42 is hinged to the power unit 41 and the second swing arm 43 is also hinged to the first swing arm 42, the active part 4 is only used to provide rotational power for the glass panel 2 and cannot limit its rotation direction. The rotation center of the glass panel 2 is transferred to the driven parts 5 on both sides of the active part 4.

[0052] To further ensure the consistency of displacement on both sides of the glass panel 2, the two driven parts 5 in the present invention need to be symmetrically arranged at both ends of any side of the glass panel 2, and the connection between the driven parts 5 at both ends and the glass panel 2 is at the same distance from the side.

[0053] Furthermore, to prevent the connection between the active part 4 and the glass panel 2 from limiting the displacement of the glass panel 2 , the distance between the connection between the active part 4 and the glass panel 2 and the side edge needs to be greater than the distance between the connection between the driven part 5 and the glass panel 2 and the side edge.

[0054] In an embodiment of the present invention, the driven parts 5 are disposed at two ends of the upper side of the glass panel 2 , and correspondingly, the active part 4 is disposed between the two driven parts 5 in the length direction of the glass panel 2 .

[0055] In this embodiment, the top of the range hood housing 1 is connected with a smoke outlet channel 3 , and any side wall of the smoke outlet channel 3 extends toward the smoke collecting chamber 10 to form a first fixing member 6 .

[0056] One end of the active part 4 is connected to the first fixing member 6 , and the other end is bonded to the glass panel 2 .

[0057] Specifically, the active part 4 includes a power unit 41 , a first swing arm 42 and a second swing arm 43 , wherein the power unit 41 is used to provide power for the glass panel 2 to rotate, and the first swing arm 42 and the second swing arm 43 transmit the power provided by the power unit 41 to the glass panel 2 .

[0058] One side of the power unit 41 is fixed to the first fixing member 6, for example, by screws, and the other side is hinged to the first swing arm 42;

[0059] One side of the first swing arm 42 is hinged to the power unit 41 , and the other side is hinged to the second swing arm 43 . The end of the second swing arm 43 is in close contact with the glass panel 2 .

[0060] Furthermore, considering that under the action of the power unit 41, the second swing arm 43 directly acts on the glass panel 2 to lift or recycle it, in order to ensure the service life of the glass panel 2, a contact plate is also provided at the end of the second swing arm 43. The contact plate is fitted and connected to the glass panel 2 and has a plate-like structure. The contact area between the contact plate and the glass panel 2 is larger than the contact area between the end of the second swing arm 43 and the glass panel 2. As the contact area increases, the stress on the glass panel 2 decreases accordingly, thereby increasing the safety of the glass panel 2 during the lifting and recycling process.

[0061] Furthermore, in order to ensure that the active part 4 in this embodiment is only used to provide rotational power, the second swing arm 43 and the contact plate are also hinged.

[0062] In this embodiment, the two driven parts 5 are symmetrically arranged at two ends of the upper side of the glass panel 2, and the distance between the connection points between the driven parts 5 at the two ends and the glass panel 2 and the upper side is the same.

[0063] On the other hand, to prevent the connection between the active part 4 and the glass panel 2 from limiting the displacement of the glass panel 2, the distance between the connection between the active part 4 and the glass panel 2 and the upper side edge must be greater than the distance between the connection between the driven part 5 and the glass panel 2 and the upper side edge.

[0064] In another embodiment of the present invention, the two driven parts 5 are disposed at two ends of the upper side of the glass panel 2 , and correspondingly, the active part 4 is disposed between the two driven parts 5 in the length direction of the glass panel 2 .

[0065] The top of the range hood casing 1 is connected to a smoke outlet channel 3, and any side wall of the smoke outlet channel 3 extends toward the smoke collecting chamber 10 to form a first fixing member 6. The power unit 41 of the active part 4 is arranged on the first fixing member 6. In other words, the active part 4 is suspended in the smoke collecting chamber 10 through the first fixing member 6. In order to ensure the structural strength of the first fixing member 6, the first fixing member 6 in this embodiment is also provided with a flange 61.

[0066] Preferably, the flange 61 extends in a direction close to the power unit 41, that is, the flange 61 does not occupy the smoke outlet channel 3, so as to avoid affecting the smoke exhaust efficiency of the range hood.

[0067] Furthermore, in this embodiment, the top of the range hood casing 1 and the top of the glass panel 2 are spaced apart to form an installation space 8 with a single-side opening, and the opening faces the smoke collecting chamber 10. Here, the installation space 8 can be used to install related components of the range hood control panel.

[0068] A third fixing member 9 is further provided at the opening of the installation space 8 toward the smoke collecting chamber 10 . In addition to the first fixing member 6 , the power unit 41 can also be fixed by the third fixing member 9 , thereby further increasing the stability of the active part 4 in the smoke collecting chamber 10 .

[0069] Furthermore, in the present embodiment, the extension direction of the third fixing member 9 is consistent with the inclination angle of the front end surface of the range hood casing 1, that is, it is consistent with the extension direction of the glass panel 2 when the smoke inlet channel is closed. If the active part 4 falls, the third fixing member 9 can also play a guiding role, so that the active part 4 slides along the third fixing member 9 instead of falling directly onto the glass panel 2 and damaging the glass panel 2.

[0070] Preferably, in this embodiment, there is a gap between a portion of the bottom edge of the first fixing member 6 and the bottom of the installation space 8 .

[0071] If the first fixing member 6 contacts the bottom of the installation space 8 , the installation spaces 8 on both sides of the first fixing member 6 are separated, which is not conducive to the smoke in the smoke collecting chamber 10 being discharged from the smoke outlet channel 3 , thereby reducing the smoke discharge efficiency.

[0072] In this embodiment, there is a gap between part of the bottom edge of the first fixing member 6 and the bottom of the installation space 8, so that the installation spaces 8 on both sides of the first fixing member 6 remain connected, and the smoke can directly enter the smoke outlet channel 3 from this gap, and this part of the bottom edge is arranged parallel to the bottom of the installation space 8, that is, the gap height is consistent, which further ensures the exhaust efficiency of the smoke.

[0073] In one embodiment of the utility model, the top of the range hood casing 1 and the top of the glass panel 2 are spaced apart to form an installation space 8. In addition to accommodating related components of the control panel, this installation space 8 can also be used to accommodate the driven part 5. The driven part 5 is an integrated structure and is used to limit the rotation path of the glass panel 2 during the lifting and recovery process.

[0074] Specifically, when the smoke inlet channel is closed, the driven part 5 is an inverted U-shaped structure, part of which is arranged in the installation space 8 and is hinged to the second fixing member 7 arranged in the installation space 8, and the other end is fitted and connected with the glass panel 2. At this time, the hinge point between the driven part 5 and the second fixing member 7 is the rotation center of the glass panel 2.

[0075] Furthermore, in this embodiment, the distance between the top of the driven part 5 and its hinge point needs to be smaller than the height of the installation space 8, thereby increasing the rotation angle of the driven part 5 and avoiding contact between the driven part 5 and the top of the installation space 8, that is, the top of the range hood casing 1, during the recovery process of the glass panel 2, thereby ensuring the smoothness of the rotation of the glass panel 2 driven by the active part 4.

[0076] Furthermore, considering that the end of the driven portion 5 is closely connected to the glass panel 2, in order to prevent the glass panel 2 from being subjected to greater stress, in this embodiment, the end of the driven portion 5 is also connected to a pushing member 51, and the pushing member 51 is a plate-like structure, which is closely arranged to the glass panel 2, and the contact area between the pushing member 51 and the glass panel 2 is greater than the contact area between the end of the driven portion 5 and the glass panel 2, thereby reducing the stress on the glass panel 2.

[0077] Preferably, in this embodiment, the contact area between the pushing member 51 and the glass panel 2 is larger than the contact area between the contact plate of the active part 4 and the glass panel 2 .

[0078] When the installation space 8 is provided with a third fixing member 9 , the third fixing member 9 needs to be provided with a corresponding avoidance gap in the rotation direction of the driven part 5 to avoid affecting the stability of the lifting and recovery actions of the glass panel 2 .

[0079] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0080] In the present invention, at least one driven part 5 is respectively arranged on both sides of the driving part 4 of the transmission device. The driving part 4 is only used to drive the glass panel 5 to rotate. At this time, the rotation center of the glass panel 2 is adjusted to the driven parts 5 on both sides of the driving part 4. The driven parts 5 are used to limit the rotation path of the glass panel 2 during its rotation, thereby ensuring the consistency of the displacement of both sides of the glass panel 2 and avoiding the situation of not being able to be tightened.

[0081] In addition, since the utility model is provided with at least two driven parts 5 to share the force, under the premise of ensuring that the glass panel 2 is tightened, the driven part 5 can also be made of a lighter and thinner material to reduce the production cost.

[0082] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
