They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. The terms "connected", "connected" and "set" used in the present invention should be understood in a broad sense. For example, they can be fixedly connected or detachably connected; they can be directly connected or indirectly connected through an intermediate component; they can be wired electrical connections, radio connections, or wireless communication signal connections. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to 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 the upper part, and the lower part is the lower part; the direction of the range hood facing the user is defined as the front, and the direction facing away from the user is defined as the rear. The fan assembly 1 is fixedly arranged on the side of the wall, and a first air duct 11 is arranged at the bottom of the fan assembly 1. A second air duct 21 is arranged 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. The lifting assembly 3 includes a fixed portion and a lifting portion that moves vertically relative to the fixed portion, and 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 hood provided by the embodiment of the present invention is in use, the smoke collecting chamber assembly 2 can move vertically with the lifting part 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 the 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 meet the needs of users of different heights for comfort, 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 the 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 located 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 the wall through 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 bottom of the housing 22 is provided with an air inlet 23, and the second air duct 21 is vertically arranged at the top of the housing 22 and communicated with the housing 22. Further, 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 collecting 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 part includes a mounting plate 31, a screw 32 and a motor 33, and the lifting part 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 on 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, 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 on the wall, the fixed part of the lifting assembly 3 can be fixed on the wall. The motor 33 is connected to one end of the screw 32 through a structure transmission connection such as a gear, so that the motor 33 can drive the screw 32 to rotate. The slider 34 is sleeved on the lead screw 32 through an internal thread, and the slider 34 is connected to the rear side of the smoke collecting chamber assembly 2. Since the slider 34 is threadedly connected to the lead screw 32 and 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 to move up and down. Preferably, a fixing plate 341 is provided on the outer side 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 when it moves up and down.

[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 on 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 relatively are respectively fixedly connected to the wall and the rear side of the smoke collecting chamber assembly 2. In this embodiment, the rear side of the smoke collecting chamber assembly 2 is designed with two vertical mounting grooves 24 for mounting the lifting assembly 3. One of the mounting grooves 24 is used to mount the lead screw slider structure, and the other mounting groove 24 is used to mount 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 lead 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 collecting chamber assembly 2, which can ensure that the accumulated oil on the inner wall of the first air duct 11 can smoothly flow into the oil cup in the smoke collecting chamber assembly 2 and will not drip onto the stove top 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 assembly 2 and the design of the large-sized air inlet 23 .

[0048] With the development of science and technology and the improvement of people's living standards, consumers' demand for kitchen appliances is also increasing. In this case, the integrated cooking center has become a highly concerned technical field. The integrated cooking center is a solution that integrates multiple cooking devices (such as ovens, steamers or steam ovens, etc.) into one device, aiming to improve the utilization and efficiency of the kitchen. The existing integrated cooking center mainly integrates the oven and the range hood. This design can make full use of the space in the kitchen and make the entire device more compact. However, the existing integrated cooking center is usually fixed, and its form is basically floor-standing, installed on the ground. Users cannot adjust the position of the oven according to their needs, and this integrated cooking center occupies the space on the countertop, limiting the user's operating convenience and experience. Secondly, when the range hood of the existing integrated cooking center is working, its flue is relatively complex, which may affect the temperature of the oven, thereby affecting the cooking effect and limiting the performance and practicality of the equipment. In addition, the oil circuit of the existing integrated cooking center is relatively complex, and the protection cost is high, which limits the reliability and maintenance convenience of the equipment.

[0049] In order to improve some existing problems of the 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, its flue structure is relatively simple, will not affect the temperature of the oven, the hanging lift hood also includes a cooking device 4, the cooking device 4 is fixedly arranged on the front side of the smoke chamber assembly 2. Preferably, the cooking device 4 is fixedly arranged on the front side of the second air duct 21. The cooking device 4 can be an oven, a steamer or a steam oven. The wall-mounted lift hood provided in this embodiment integrates the cooking device 4 and is installed on the wall. The user can adjust the position of the cooking device 4 (such as an oven) according to their needs, and can make full use of the kitchen space, making the entire device more compact, not occupying the space of the counter top, saving the kitchen space, and improving the user's operation convenience and experience. Secondly, the wall-mounted lift hood affects the cooking effect when the hood is working, giving full play to the performance and practicality of the equipment. In addition, the oil circuit of the wall-mounted lift hood is relatively simple, the protection cost is low, and the reliability and maintenance convenience of the equipment are improved. In addition, the cooking device 4 is arranged on the front side of the smoke chamber assembly 2, which can effectively block the escape of the oil smoke below, play the role of collecting the oil smoke, and further improve the smoking 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, which are prior arts 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 collection chamber assembly 2; seen from the side, the oven is located at the right part of the smoke collection chamber assembly 2. Since the second air duct 21 on the back of the smoke collection 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 component 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, such as Figure 4 , Figure 5 As shown, a recessed portion 41 is provided at the middle position of the top of the cooking device 4, and a raised portion 14 corresponding to the recessed portion 41 is provided at the middle position 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 embodiment of the present invention further provides an integrated cooking center, comprising a stove arranged on a table and the above-mentioned wall-mounted lifting range hood. The stove can be a gas stove, etc., and is located below the smoke collecting chamber assembly 2.

[0052] In one embodiment of the present invention, the integrated cooking center includes the above-mentioned wall-mounted lifting range hood with cooking equipment. By installing the cooking equipment 4 (such as an oven) on the front of the smoke chamber assembly 2 of the above-mentioned wall-mounted lifting range hood, and using a sliding lifting assembly 3, the oven can be lifted and lowered. At the same time, since the oven is installed in the front of the range hood, the lifting and lowering of the oven and the range hood is more convenient. The fan assembly 1 is a fixed structure. This structure integrates the oven on the wall-mounted lifting range hood, uses the space on the wall without occupying the kitchen counter space, thereby greatly saving the kitchen space, solving the problem that the existing integrated cooking center is usually fixed on the countertop, occupying the countertop space and the user cannot adjust the position of the oven according to their needs, and improving the user's operation convenience and experience. The integrated cooking center provided in this embodiment adopts an independent air duct structure (the first air duct 11 and the second air duct 21), which solves the problem that the existing integrated cooking center has a relatively complex flue when the range hood is working, which may affect the temperature of the oven and thus affect the cooking effect, and improves the performance and practicality of the equipment. The integrated cooking center provided in this embodiment adopts a sliding lifting assembly 3, which has a simple structure, low cost, and is not prone to failure. The sliding lifting assembly 3 can realize the up and down movement of the oven. When the oven needs to be used, the oven can be lowered to facilitate the user to take the baking tray and cook. When not in use, the oven will rise up and be flush with the bottom of the fan assembly 1, making the kitchen beautiful as a whole and not blocking the place. In order 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 not less than the lifting height of the oven, so that the oven will not block the air inlet 23 when it 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 only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
