They are only for the convenience of describing the present invention and do not require that the present invention be constructed and operated in a specific orientation. Therefore, they should not be understood as limiting the present invention. The terms "connected", "connected" and "disposed" used in the present invention should be understood in a broad sense. For example, they can mean fixed connection or detachable connection; direct connection or indirect connection through an intermediate component; wired electrical connection, radio connection, or wireless communication signal connection. For those skilled in the art, the specific meanings of the above terms can be understood according to the specific circumstances.

[0038] like Figure 1 As shown, the embodiment of the present invention provides a wall-mounted lifting range hood, comprising a fan assembly 1, a smoke collecting chamber assembly 2 and a lifting assembly 3. For the convenience of description, the definition Figure 1The upper part is defined as up, and the lower part is defined as down; the direction of the range hood facing the user is defined as front, and the direction facing away from the user is defined as back. The fan assembly 1 is fixed on the side of the wall, and a first air duct 11 is provided at the bottom of the fan assembly 1. A second air duct 21 is provided at the top of the smoke collecting chamber assembly 2, and the first air duct 11 and the second air duct 21 can be relatively slidably plugged in. The lifting assembly 3 includes a fixed portion and a lifting portion that moves vertically relative to the fixed portion, the fixed portion is fixed on the side of the wall, and the lifting portion is connected to the smoke collecting chamber assembly 2.

[0039] When the wall-mounted lifting range hood provided by the embodiment of the present invention is in use, the smoke collecting chamber assembly 2 can move vertically along with the lifting portion of the lifting assembly 3, while maintaining the sealed connection between the first air duct 11 and the second air duct 21, and can efficiently absorb oil smoke according to different heights. For example, when stir-frying over a high fire, the oil smoke height is high, and the smoke collecting chamber assembly 2 can be raised; when stir-frying over a low fire, the oil smoke height is low, and the smoke collecting chamber assembly 2 can be lowered. At the same time, after being raised or lowered, the smoke collecting chamber assembly 2 can adapt to the user's needs for user comfort of different heights, so that the air inlet of the smoke collecting chamber assembly 2 is kept at a comfortable position for the user, such as below the head, to prevent oil smoke from entering the user's mouth and nose and affecting the user experience.

[0040] In order to adapt to the up and down movement of the second air duct 21, when the second air duct 21 is at the top of the lifting height, the first air duct 11 and the second air duct 21 overlap by a certain length L in the vertical direction, and the lifting distance of the second air duct 21 is less than the overlapping length L of the first air duct 11 and the second air duct 21, so as to ensure that the oil circuit of the range hood (the first air duct 11 and the second air duct 21) is in a relatively closed space.

[0041] like Figure 2 As shown, in one embodiment of the present invention, the fan assembly 1 includes a wind cabinet 12 and a fan 13 located in the wind cabinet 12. The first air duct 11 is vertically arranged at the bottom of the wind cabinet 12 and communicates with the wind cabinet 12. The wind cabinet 12 can be hung on a wall via a hanging plate 121.

[0042] like Figure 2 As shown, in one embodiment of the present invention, the smoke collecting chamber assembly 2 includes a housing 22 and the second air duct 21. The housing 22 is provided with an air inlet 23 at the bottom. The second air duct 21 is vertically provided at the top of the housing 22 and communicates with the housing 22. Furthermore, the smoke collecting chamber assembly 2 is in an inverted T-shape, and the air inlet 23 is in a horizontal bar shape to enhance the smoking effect.

[0043] In one embodiment of the present invention, the lifting component 3 can be an electric push-pull rod. In this case, the fixed part is the main body of the electric push-pull rod, which is fixed on the wall; the lifting part is a retractable push-pull rod, which is fixedly connected to the smoke chamber component.

[0044] like Figure 3 As shown, in one embodiment of the present invention, the lifting assembly 3 is a screw-slider structure, wherein the fixed portion includes a mounting plate 31, a screw 32 and a motor 33, and the lifting portion is a slider 34. Specifically, the mounting plate 31 includes a top plate 311 and a bottom plate 313. The top plate 311 and the bottom plate 313 are fixed to the wall, the screw 32 is vertically arranged between the top plate 311 and the bottom plate 313, and the two ends of the screw 32 are rotatably connected to the top plate 311 and the bottom plate 313, respectively, for example, pivotally connected. In this embodiment, the mounting plate 31 also includes a side plate 312, and the top plate 311 and the bottom plate 313 are both fixedly connected to the side of the side plate 312. By fixing the side plate 312 to the wall, the fixed portion of the lifting assembly 3 can be fixed to the wall. The motor 33 is connected to one end of the screw 32 through a structure such as a gear, so that the motor 33 can drive the screw 32 to rotate. The slider 34 is internally threaded onto the lead screw 32 and is connected to the rear side of the smoke collecting chamber assembly 2. Because the slider 34 is threadedly connected to the lead screw 32 and is fixedly connected to the smoke collecting chamber assembly 2, when the lead screw 32 rotates, the slider 34 can move up and down, thereby driving the smoke collecting chamber assembly 2 up and down. Preferably, a fixing plate 341 is provided on the outside of the slider 34 for connecting to the rear side of the smoke collecting chamber assembly 2 to improve the stability of the connection and the stability of the smoke collecting chamber assembly 2 during up and down movement.

[0045] like Figure 1 、 Figure 2 As shown, in order to further ensure the stability and accuracy of the smoke collecting chamber assembly 2 when it moves up and down, in a preferred embodiment of the present invention, the lifting assembly 3 also includes a vertical slide rail 35, which is fixed to the wall, and the rear side of the smoke collecting chamber assembly 2 is provided with a slide groove matching the slide rail 35, and the two sides of the slide rail 35 that can slide relative to each other are respectively fixedly connected to the wall and the rear side of the smoke collecting chamber assembly 2. In this embodiment, two vertical mounting grooves 24 are designed on the rear side of the smoke collecting chamber assembly 2 for installing the lifting assembly 3. One of the mounting grooves 24 is used to install the screw slider structure, and the other mounting groove 24 is used to install the slide rail 35. The slide rail 35 is used to assist in positioning to ensure that the smoke collecting chamber assembly 2 is in a vertical lifting process, and the motor 33 provides the lifting power for the smoke collecting chamber assembly 2 through the screw slider structure.

[0046] In a preferred embodiment of the present invention, the first air duct 11 is located inside the second air duct 21, that is, the air inlet of the fan assembly 1 is inside the air outlet of the smoke chamber assembly 2, which can ensure that the accumulated oil on the inner wall of the first air duct 11 can flow smoothly into the oil cup in the smoke chamber assembly 2 and will not drip onto the stove surface below.

[0047] like Figure 1 、 Figure 2 As shown, in a preferred embodiment of the present invention, the cross-sections of the first air duct 11 and the second air duct 21 are rectangular, so as to realize the ultra-thin design of the smoke collecting chamber component 2 and the design of the large-sized air inlet 23 .

[0048] With the advancement of technology and the improvement of people's living standards, consumer demand for kitchen appliances is also increasing. In this context, integrated cooking centers have become a highly sought-after technology area. An integrated cooking center integrates multiple cooking appliances (such as an oven, steamer, or steam oven) into a single device, aiming to improve kitchen utilization and efficiency. Existing integrated cooking centers primarily integrate an oven and range hood. This design maximizes kitchen space and makes the entire device more compact. However, existing integrated cooking centers are typically fixed, typically floor-standing, mounted on the ground. Users cannot adjust the oven's position according to their needs, and these integrated cooking centers occupy countertop space, limiting user convenience and user experience. Furthermore, the flue gas duct of existing integrated cooking centers is complex when the range hood is operating, which may affect the oven's temperature, thereby affecting cooking results and limiting the device's performance and practicality. Furthermore, the oil circuitry of existing integrated cooking centers is complex, resulting in high maintenance costs and limiting reliability and ease of maintenance.

[0049] In order to improve some existing problems of the existing integrated cooking center in terms of space utilization, operation convenience, performance, reliability and maintenance convenience, such as Figure 4 、 Figure 5As shown, in one embodiment of the present invention, the wall-mounted lift range hood has a relatively simple flue structure that does not affect the temperature of the oven. The wall-mounted lift range hood also includes a cooking device 4, which is fixedly mounted in front of the smoke chamber assembly 2. Preferably, the cooking device 4 is fixedly mounted in front of the second air duct 21. The cooking device 4 can be an oven, a steamer, or a steam oven. The wall-mounted lift range hood provided in this embodiment integrates the cooking device 4 and is mounted on the wall. Users can adjust the position of the cooking device 4 (e.g., an oven) according to their needs, making full use of kitchen space, making the entire device more compact and not occupying counter space, saving kitchen space and improving user convenience and user experience. Furthermore, the wall-mounted lift range hood does not affect the cooking effect during operation, fully utilizing the device's performance and practicality. Furthermore, the wall-mounted lift range hood has a relatively simple oil circuit, low maintenance costs, and improved device reliability and maintenance ease. Furthermore, the cooking device 4 is located in front of the smoke chamber assembly 2, effectively blocking the escape of oil smoke from below, thereby collecting the oil smoke and further improving the smoke extraction effect of the smoke chamber assembly 2. In order to obtain the best smoke collection effect, the distance between the bottom of the cooking device 4 and the air inlet 23 of the smoke collection chamber assembly 2 is less than or equal to 80 cm.

[0050] In this embodiment, the cooking device 4 is an oven, which is composed of a cavity assembly, an electrical component assembly, an insulation layer, an oven cover assembly, and a door assembly. This is a prior art and will not be described in detail. Figure 6 、 Figure 7 As shown, the oven of this embodiment is different from the existing oven in that the whole machine presents an F-shaped structure. Seen from the front, the oven is located at the lower part of the fan assembly 1 and the upper part of the smoke chamber assembly 2; seen from the side, the oven is located at the right part of the smoke chamber assembly 2. Since the second air duct 21 on the back of the smoke chamber assembly 2 occupies part of the space, in order to ensure that the cavity of the oven has sufficient depth, the thickness of the whole machine is relatively large, and the fan assembly 1 needs to be hidden in the kitchen cabinet, and its thickness is limited. In order to make the top of the oven level with the thickness of the fan assembly 1, the cross-section of the oven presents an L-shaped structure, that is, the outer side surface of the top of the oven is flush with the outer side surface of the fan assembly 1, and the outer side surface of the bottom of the oven protrudes from the outer side surface of the fan assembly 1, so that the electrical components on the top of the oven are all within the depth of the kitchen cabinet. Furthermore, in order to reduce the height of the whole machine, as Figure 4 、 Figure 5 As shown, a recessed portion 41 is provided in the middle of the top of the cooking device 4, and a raised portion 14 corresponding to the recessed portion 41 is provided in the middle of the bottom of the fan assembly 1, so that the fan assembly 1 can be embedded and installed in the recessed portion 41. The electrical component components of the cooking device 4 are arranged on both sides of the recessed portion 41, and the fan 13 of the fan assembly 1 is arranged in the raised portion 14, which greatly reduces the height of the entire machine.

[0051] The present invention also provides an integrated cooking center, comprising a stove on a table and the above-mentioned wall-mounted lift range hood. The stove can be a gas stove, etc., and is located below the smoke chamber assembly 2.

[0052] In one embodiment of the present invention, the integrated cooking center includes the aforementioned wall-mounted lift range hood with cooking equipment. By mounting a cooking device 4 (e.g., an oven) in front of the smoke chamber assembly 2 of the wall-mounted lift range hood and employing a sliding lift assembly 3, the oven can be raised and lowered. Furthermore, since the oven is mounted in front of the range hood, raising and lowering the oven and range hood is more convenient. The fan assembly 1 is a fixed structure. This design integrates the oven onto the wall-mounted lift range hood, utilizing wall space instead of kitchen countertop space, significantly saving kitchen space. This solves the problem of existing integrated cooking centers typically being fixed to the countertop, occupying countertop space and preventing users from adjusting the oven's position as needed, thereby improving user convenience and user experience. The integrated cooking center provided by this embodiment utilizes independent air duct structures (first air duct 11 and second air duct 21), addressing the problem of existing integrated cooking centers with complex flue gas ducts when the range hood is operating, which can affect the oven's temperature and thus the cooking effect, thereby improving the performance and practicality of the device. The integrated cooking center provided by this embodiment employs a sliding lift assembly 3, which is simple in structure, low in cost, and less prone to failure. The sliding lifting assembly 3 allows the oven to move up and down. When the oven is needed, it can be lowered, making it easier for the user to access the baking tray and start cooking. When not in use, the oven rises to align with the bottom of the fan assembly 1, making the kitchen aesthetically pleasing and unobstructed. To enhance the smoking effect, the bottom of the smoke chamber assembly 2 in this embodiment has a larger shoulder width, which is the same as the width of a traditional cabinet, and its height is no less than the lifting height of the oven, so that the air inlet 23 is not blocked when the oven is lowered. The second air duct 21 has a smaller shoulder width, and its width and height correspond to the size of the oven.

[0053] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
