Range hood is worked using the principle of fluid dynamics, and oil fume is sucked and discharged by centrifugal fan installed in the range hood, and filter screen is used to filter part of oil particles. However, since range hood is usually large in size, it is easy to cause strong oppression when used by user in smaller kitchen space, and use experience is poor, and since cabinet can only close and hide fan box, machine body below fan box is usually exposed in kitchen, so that overall appearance and coordination are still poor, and overall kitchen aesthetics is lacking.

[0003] Therefore, a lifting type range hood appears in prior art, i.e. machine body is hidden in upper cabinet, when range hood works, machine body is lowered from cabinet to meet the demand of smoke inlet height, smoke gathering range and negative pressure height of oil fume suction, and when range hood does not work, machine body is lifted up to be hidden in cabinet together with fan box, as shown in Figure 5 However, the above structure mainly has the following three problems:

[0004] (1) since the horizontal dimension of machine body is usually long, it leads to that cabinet needs to leave enough space to accommodate machine body, so that cabinet needs to sacrifice more storage space, and this is undoubtedly a big defect for kitchen which urgently needs storage space;

[0005] (2) since part of machine body is used together with fan after being lifted up, due to certain size of fan itself and machine body behind it, it makes the longitudinal depth of cabinet be relatively deep, leads to that cabinet depth is different from conventional size of cabinet, occupies upper space of kitchen, i.e. still exists certain degree of oppression, and cost of cabinet is increased for user;

[0041] Referring to Figure 1 The range hood provided by the embodiment of the present application comprises a body 1 and a fan box 2, the body 1 is arranged in an accommodating groove 51 formed in the mounting wall 5, the body 1 is arranged below the fan box 2, the vertical projection of the body 1 and the fan box 2 at least partially does not overlap, and the body 1 and the fan box 2 are connected through a connecting part 3. Specifically, the body 1 is located below the fan box 2, the fan box 2 is provided with a fan 4 for generating negative pressure, and the body 1 is used for allowing oil fume to enter. Different from the traditional range hood, the body 1 of the present application is outwardly protrudingly arranged near the side of the mounting wall 5, so that the body 1 and the fan box 2 are arranged in a staggered manner near the side of the mounting wall 5, while the body 1 and the fan box 2 of the traditional range hood are usually arranged in the same vertical plane near the side of the mounting wall 4. Therefore, the body 1 and the fan box 2 are directly connected, and there is usually no transition section between the body 1 and the fan box 2, or even if there is a transition section, the transition section is also connected in the same vertical plane with the body 1 and the fan box 2. In the present application, the body 1 is arranged in a staggered manner with the fan box 2 near the side of the mounting wall 5, the accommodating groove 51 is formed in the mounting wall, and the body 1 is embedded in the accommodating groove 51, so that the body 1 is hidden in the mounting wall 5. In order to better connect the fluid communication between the fan box 2 and the body 1 and ensure the oil fume suction effect, the connecting part 3 is arranged between the body 1 and the fan box 2, and the vertical projection of at least part of the connecting part 3 in the horizontal direction does not overlap with the fan box 2. In the present application, the body is embedded in the accommodating groove, and the surface of the body is flush with the surface of the mounting wall when the range hood is not working, so that the body is hidden and arranged, and the overall appearance and coordination of the kitchen are maintained.

[0042] In some specific embodiments, referring to Figure 1, the connecting part 3 comprises a first connecting part 31 and a second connecting part 32, the first connecting part 31 and the second connecting part 32 are oppositely arranged to form a fluid channel between the machine body 1 and the fan box 2. Specifically, the first connecting part 31 and the second connecting part 32 can be arranged in a circular arc shape, a straight line shape, a broken line shape (including a right angle) or other shapes, and when they are arranged in a circular arc shape, they are convex to the fluid channel; preferably, when the first connecting part 31 and the second connecting part 32 adopt the shape of being convex to the fluid channel, the fluid channel is narrowed in the middle region, and the oil fume immediately enters the wide flow channel after passing through the narrow flow channel in the middle of the fluid channel, thereby forming a Venturi effect structure, so that the flow rate of the oil fume in the fluid channel is accelerated, and the smoke exhaust efficiency is improved. Further, for the first connecting part 31 arranged in a circular arc shape or a broken line shape convex to the fluid channel, it is beneficial to accumulate oil stains at the convex position from the back plate 21 of the fan box 2 and drop into the oil cup 62 arranged in the lower region of the machine body, facilitating the collection of oil stains. For the second connecting part 32 arranged in a circular arc shape or a broken line shape, it has a flow guiding effect, avoiding the formation of vortex of oil fume in the area close to the fluid channel of the bottom plate 23 of the fan box 2.

[0043] In some specific embodiments, the connecting part 3 is integrally formed with the fan box 2 or integrally formed with the machine body 1.

[0044] In some specific embodiments, the connecting part 3 is a detachable structure, thereby facilitating the installation of the range hood, especially the installation when the machine body 1 is embedded in the accommodating groove 51; wherein the connecting part 3 can be a part of the accommodating groove 51, that is, the connecting part 3 is also formed by slotting the installation wall 5, in order to prevent oil leakage at both ends of the second connecting part 52, a sealing strip can be arranged at both ends of the second connecting part 52 respectively.

[0045] In some specific embodiments, please refer to Figure 2 The machine body 1 comprises a first machine body 11 and a second machine body 12, the first machine body 11 and the second machine body 12 are oppositely arranged, a fluid channel is formed between the first machine body 11 and the second machine body 12, and the shapes of the first machine body 11 and the second machine body 12 are rectangular.

[0046] The fan box 2 comprises a back plate 21 and a bottom plate 23, the back plate 21 is arranged close to the installation wall 5 side, the bottom plate 23 is arranged close to the machine body 1 side and perpendicular to the back plate 21; specifically, the fan box 2 further comprises a front plate 22, the front plate 22 is arranged in parallel with the back plate 21, and the bottom plate 23 is vertically arranged on the side close to the machine body 1 of the front plate 22 and the back plate 21.

[0047] The first machine body 11 is connected with the back plate 21 through the first connecting part 31, and the second machine body 12 is connected with the bottom plate 23 through the second connecting part 32, so as to realize the fluid communication between the machine body 1 and the inside of the fan box 2.

[0048] In some specific embodiments, the fan box 2 is provided with a fan 4, and the fan 4 is obliquely arranged in the fan box 2; wherein the air inlet of the fan 4 is directed to the side of the connecting part 3. Thus, a straight channel is formed between the connecting part 3 and the air inlet of the fan 1, and the oil fume is discharged from the inlet without multiple large-angle turning in the range of the smoke machine, thereby reducing the risk of vortex formation in the range of the smoke machine, reducing the loss of air volume, and reducing the noise of the smoke machine to a certain extent.

[0049] In some specific embodiments, please refer to Figure 3 , the angle α between the connecting line between the center of the connecting part 3 and the center of the air inlet and the central axis of the fan 4 is -30°≤α≤30°. Specifically, the center of the connecting line between the first connecting part 31 and the second connecting part 32 is A, the center of the air inlet of the fan is O, the connecting line between the two points is AO, the central axis of the fan 1 is BC, and the angle between the connecting line AO and BC is α, wherein the range of the angle α is -30°≤α≤30°; since the shape of the first connecting part 31 and the second connecting part 32 is determined, the connecting line AO is also determined, therefore, the size of the angle α is mainly affected by the inclination angle of the fan 1. If α is less than -30°, it means that the inclination angle of the fan 1 is relatively large, and the connection design between the air outlet of the fan and the flue will increase the complexity, and may also affect the air outlet effect; moreover, the more the fan 1 is inclined, the longer the longitudinal depth of the fan box 2 will be, which will cause the upper area of the range hood to be too large, increasing the sense of oppression; in addition, for the cabinet users, it will cause the user to be unable to package the cabinet or need to make a large cabinet body; if α is greater than 30°, it means that the inclination angle of the fan is small, and it tends to be placed vertically, at this time, since the air inlet is no longer directed to the connecting part 3, the oil fume flowing through the connecting part 3 needs to turn and enter the fan 5 from the air inlet when entering the fan box 2, which causes the oil fume to be discharged from the inlet.

[0050] In some specific embodiments, please refer to Figure 4, another fan 5 is set in an inclined angle, the line segment DO is perpendicular to the back plate 21 and passes through the center O of the fan air inlet, the central axis of the fan 1 is BC, the angle between the line segment DO and BC is β, wherein the angle β is in the range of 15°≤β≤75°; since the connecting line DO is determined, the size of the angle β is mainly affected by the inclined angle of the fan 5. If β is greater than 75°, it means that the fan is inclined at a larger angle, and the design complexity of the connection between the fan air outlet and the flue will increase, which may also affect the air outlet effect. Moreover, the more inclined the fan is, the longer the longitudinal depth of the fan box will be, which will cause the upper area of the range hood to be too large and increase the sense of oppression. In addition, for cabinet users, it will cause the user to be unable to package the cabinet or need to make a large cabinet body. If β is less than 15°, it means that the fan 5 is inclined at a smaller angle and tends to be placed vertically. At this time, since the air inlet is no longer directed towards the connecting segment, the oil fume flowing through the connecting segment needs to turn around and enter the fan from the air inlet when entering the fan box, which causes the oil fume extraction effect to be poor.

[0051] In some specific embodiments, the thickness D of the machine body 1 is 10mm≤D≤40mm; the depth H of the accommodating groove 51 is 0.9D≤H≤1.1D. Specifically, the machine body 1 is a rectangular body, and the thickness D of the machine body is in the range of 10-40mm; when the thickness D of the machine body is less than 10mm, the inner cavity space of the machine body is too small, which will cause the oil fume extraction channel to be too narrow, and a large amount of oil fume cannot be timely removed, thereby causing poor oil fume extraction effect; when the thickness D of the machine body is greater than 40mm, since the machine body needs to be embedded in the installation wall and be flush with the installation wall plane, the depth of the accommodating groove 51 is too deep, which may affect the structure of the wall. Therefore, the preferred range of the thickness D of the machine body is 20-30mm, which can ensure the oil fume extraction effect while avoiding a large impact on the structure of the installation wall 5. Preferably, the depth H of the accommodating groove 51 is in the range of 0.9D≤H≤1.1D; when the depth H is greater than 1.1D, since the accommodating groove 51 is too deep, the machine body 1 will appear concave, which on the one hand will cause the machine body 1 to be farther away from the smoke source, resulting in poor oil fume extraction effect, and on the other hand will cause the concave part around the machine body 1 to accumulate oil fume, resulting in poor appearance; when H is less than 0.9D, since the accommodating groove 51 is too shallow, the machine body 1 will be too protruding on the wall surface, which will cause the overall kitchen wall surface to be less coordinated, and at the same time, the machine body 1 and the accommodating groove 51 will be easy to hide dirt and difficult to clean; therefore, the preferred range of the depth H of the accommodating groove 51 is 0.9D≤H≤1.1D, which can not only satisfy the better embedding of the machine body 1 in the accommodating groove 51, but also avoid affecting the appearance and coordination of the kitchen wall surface and the structure of the installation wall 5.

[0052] In some specific embodiments, please refer to Figure 1 and Figure 2The second body 12 is provided with an oil fume inlet close to the second connecting part 32, and the oil fume inlet is provided with a first panel 13. The first panel 13 is in a closed state when the range hood is not working, and the first panel 13 is opened to form a fume gathering area when the range hood is working. In the application, the whole body 1 is hidden in the mounting wall 5, and the oil fume inlet is farther away from the pot compared with the oil fume inlet of the conventional range hood. Therefore, preferably, when the first panel 13 is opened to the limit position, the farthest end of the first panel 13 away from the second body 12 should be beyond the center line of the vertical projection plane of the fan box 2, so as to ensure sufficient fume gathering range, prevent oil fume from escaping, and improve the oil fume suction effect.

[0053] In some specific embodiments, a decorative piece is arranged between the body 1 and the accommodating groove 51. By arranging the decorative piece between the body 1 and the accommodating groove 51, on the one hand, the decorative piece can play a role in connecting decoration and improve the appearance of the kitchen, and on the other hand, the decorative piece can fill the gap between the body 1 and the accommodating groove 51, prevent oil stains from accumulating in the gap, and facilitate cleaning and maintenance for the user.

[0054] In some specific embodiments, the second body 12 is provided with an accommodating cavity 6 away from the fan box 2, and the accommodating cavity 6 is provided with a second panel 61 covering the accommodating cavity 6. By arranging the accommodating cavity 6, it is convenient to store articles, and the second panel 61 can also be opened and closed.

[0055] In some specific embodiments, the accommodating cavity 6 is provided with an oil cup 61 and an oil stain measuring device 62, and the oil stain measuring device 62 is used to measure the oil stain capacity in the oil cup 61. Preferably, the oil stain measuring device 62 can be a microswitch, a weighing sensor or a liquid sensor, etc. By arranging the oil stain measuring device 62, when the oil stain capacity in the oil cup 61 reaches the upper limit of the capacity, the user is reminded to clean the oil cup 61 in time to prevent oil stains from overflowing.
