[0031] See Figure 1 and Figure 2The oil fume extractor provided by the embodiment of the application comprises a machine body 1, a fan box 2 and a first air duct 21; the machine body 1 is arranged below the fan box 2, and the first air duct 21 is arranged in the fan box 2 and used for connecting the machine body 1 and the fan box 2; the machine body 1 and the first air duct 21 are arranged in a receiving groove 41 of a mounting wall 4. Specifically, the machine body 1 and the first air duct 21 are arranged on the same axis, and the machine body 1 and the first air duct 21 are flushly arranged on the side of the mounting wall 4; preferably, the outer contour of the machine body 1 and the first air duct 21 on the side close to the mounting wall 4 is the same in size as the outer contour of the receiving groove 41, so that the machine body 1 and the first air duct 21 are completely embedded in the receiving groove 4 and are arranged in close contact with the inner wall of the receiving groove 4. When the oil fume extractor is not working, the surface of the machine body 1 is flush with the surface of the mounting wall 4, so that the machine body 1 is hidden and arranged, and the overall appearance and coordination of the kitchen are maintained; and compared with the traditional oil fume extractor, the air duct is moved backward, so that the space on the air inlet side of the fan is larger, and the oil fume extraction effect is improved.

[0032] In some specific embodiments, the thickness D of the machine body 1 is 10mm≤D≤40mm, and the depth H of the receiving groove 41 is 0.9D≤H≤1.25D. 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 1 is too small, which leads to a narrow oil fume extraction channel, and a large amount of oil fume cannot be timely removed when entering, so that the oil fume extraction effect is poor; when the thickness D of the machine body 1 is greater than 40mm, the machine body 1 needs to be embedded in the mounting wall 4 and flush with the mounting wall 4, so that the depth of the receiving groove 41 is too deep, which may affect the structure of the wall. Therefore, the preferred range of the thickness D of the machine body 1 is 20-30mm, which can ensure the oil fume extraction effect and avoid affecting the structure of the mounting wall 4. At the same time, according to the thickness D of the machine body 1 being 10mm≤D≤40mm, preferably, the depth H of the receiving groove 41 is in the range of 0.9D≤H≤1.25D; when the depth H of the receiving groove 41 is greater than 1.25D, the receiving groove 41 is too deep, which leads to the machine body 1 being concave, on the one hand, the machine body 1 is farther away from the smoke source, leading to poor oil fume extraction effect, and on the other hand, the concave part around the machine body 1 accumulates oil fume, leading to poor appearance; when the depth H of the receiving groove 41 is less than 0.9D, the receiving groove 41 is too shallow, leading to the machine body 1 being too protruding from the surface of the mounting wall 4, the overall coordination of the kitchen wall surface is poor, and the machine body 1 and the receiving groove 41 are prone to dirt accumulation and difficult to clean.

[0033] In some specific embodiments, please refer to Figure 1The fan box 2 is provided with a fan 3, and the length L of the fan blade of the fan 3 is (80+H)≤L≤(200+H). Specifically, in the case of keeping the size of the air duct and the size of the fan box same as those of the conventional low-suction range hood, the size of the fan is increased, so that the air volume of the fan is increased, thereby improving the oil fume suction effect. Compared with the conventional low-suction range hood, the space at the rear side of the fan box is equivalent to extending a certain size backward, that is, in the case of keeping the size of the fan box same as that of the conventional low-suction range hood, the length L of the fan blade of the present application can be (80+H)mm≤L≤(200+H)mm, while the length L of the conventional fan blade is in the range of 80mm≤L≤200mm. It should be noted that if the fan is a double-inlet fan, the length of the fan blade refers to the sum of the lengths of the left and right fan blades.

[0034] In some specific embodiments, please continue to refer to Figure 1 The bottom plate of the fan box 2 is provided with a second smoke inlet close to the second air duct 22. By arranging the second air duct 22 on the other side of the fan 3 and opening the second smoke inlet on the bottom plate of the fan box 2, the oil fume that escapes from the smoke gathering area of the first smoke gathering plate 11 to the bottom area of the fan box 2 can enter the second smoke inlet and be discharged in the second air duct 22, thereby avoiding the escape of oil fume and improving the oil fume suction efficiency of the range hood.

[0035] In some specific embodiments, the fan 3 is a double-inlet fan. Specifically, when the first air duct 21 and the second air duct 22 are arranged on the left and right sides of the fan 3 respectively, the fan 3 is a double-inlet fan, so that the oil fume that escapes from the smoke gathering area of the first smoke gathering plate 11 to the bottom area of the fan box 2 can still be sucked by the fan, enter the second smoke inlet and be discharged in the second air duct 22, thereby avoiding the escape of oil fume and improving the oil fume suction efficiency of the range hood.

[0036] In some specific embodiments, the second smoke inlet is provided with a second smoke baffle 23, and the rotation angle γ of the second smoke baffle 23 is 70°≤γ≤120°. Specifically, the rotation angle of the second smoke baffle 23 from the closed state to the open state is denoted as γ, and the range is 70°≤γ≤120°. Since the first smoke baffle 11 is arranged on the machine body 1, when γ is less than 70°, the opening angle of the second smoke baffle 23 is too small, which may cause the second smoke baffle 23 to be blocked by the first smoke baffle 11 (i.e., the vertical projection of the second smoke baffle 23 overlaps the first smoke baffle 11), and there is no effective gap in the vertical direction for the oil fume to flow. Therefore, when the opening angle of the second smoke baffle 23 is too small, the second smoke inlet cannot play the effect of top smoke suction; and when γ is greater than 120°, since the second smoke inlet is relatively close to the user, if the opening angle is too large, the outward opening range of the second smoke baffle 23 will be large, which will block the user's line of sight and affect the user's cooking experience. Therefore, the rotation angle γ of the second smoke baffle is 70°≤γ≤120°, which can not only avoid blocking the user's line of sight in the open state of the second smoke baffle 23, but also improve the oil fume suction effect of the range hood.

[0037] In some specific embodiments, please refer to Figure 1 , the top plate of the fan box 2 is arranged on the side close to the accommodating groove 41 relative to the accommodating groove 41. Specifically, the top plate of the fan box 2 is parallel to the bottom plate of the fan box 2, and a predetermined distance is arranged between the top plate of the fan box 2 and the bottom plate of the fan box 2 for accommodating the fan 3. The top plate of the fan box 2 is arranged downwardly inclined relative to the accommodating groove 41 on the side close to the accommodating groove 41, which can be connected by an inclined line or an arc, so as to avoid a small amount of oil fume accumulating at the top right angle of the accommodating groove 41, preventing vortex or whistling.

[0038] In some specific embodiments, please continue to refer to Figure 1 , the bottom plate of the fan box 2 is arranged downwardly inclined relative to the machine body 1 on the side close to the machine body 1, which can be connected by an inclined line or an arc, so as to make the oil fume enter, and due to the guiding effect of the inclined line or the arc, avoid the oil fume forming vortex at the area of the bottom plate of the fan box 2 close to the fluid passage.

[0039] In some specific embodiments, the side of the fan box 2 away from the first air duct 21 is provided with a storage part, and the storage part is detachably connected with the fan box 2. As a preferred, in the case of keeping the size of the air duct, the size of the fan and the size of the traditional low suction type range hood being the same, since the air duct is moved to the accommodating groove 41 opened in the installation wall 4, the front side space of the same size fan box 2 is necessarily empty. Therefore, the detachable seasoning cabinet and other storage parts for placing articles can be arranged in the empty area, thereby providing more storage space for the kitchen which is already narrow; wherein the storage part is detachably connected with the fan box 2, which can also facilitate the installation and removal of the storage part.

[0040] In some specific embodiments, a heat insulation layer is arranged between the machine body 1 and the accommodating groove 41. Since the temperature of the oil fume is generally high, if no heat insulation layer is arranged between the machine body 1 and the accommodating groove 41, the high-temperature oil fume will be transmitted to the accommodating groove 41 through the machine body 1, thereby causing the temperature of the wall around the accommodating groove 41 to be too high, and the wall around the accommodating groove 41 will be bulged due to thermal expansion and contraction, or the tiles covered on the wall will be warped and detached. Therefore, by arranging the heat insulation layer between the machine body 1 and the accommodating groove 41, the wall around the accommodating groove 41 is prevented from being bulged or the tiles covered on the wall from being warped and detached.

[0041] In some specific embodiments, a decorative piece can be further arranged between the machine body 1, the first air duct 21 and the accommodating groove 41. By arranging the decorative piece between the machine body 1, the first air duct 21 and the accommodating groove 41, on the one hand, the decorative piece can play a role in connection and decoration, thereby improving the appearance of the kitchen, and on the other hand, the decorative piece can fill the gap between the machine body 1, the first air duct 21 and the accommodating groove 41, thereby preventing oil stains from accumulating in the gap and facilitating the user to clean and maintain.

[0042] In some specific embodiments, a first smoke inlet is arranged on the machine body 1 close to the fan box 2, and a first smoke plate 11 is arranged on the first smoke inlet. The first smoke plate 11 is in a closed state when the extractor hood is not working, and the first smoke plate 11 is opened to form a smoke gathering area when the extractor hood is working. In the present application, since the machine body 1 is entirely hidden in the installation wall 5, the first smoke inlet is farther away from the cooking utensils than the smoke inlet of a conventional extractor hood. Therefore, preferably, when the first smoke plate 11 is opened to the limit position, the farthest end thereof away from the second machine body 12 should be beyond the center line of the vertical projection plane of the fan box 2, so as to ensure a sufficient smoke gathering range and prevent the oil fume from escaping, thereby improving the oil fume extraction effect.

[0043] The present application discloses an extractor hood. The extractor hood provided by the present application comprises a machine body, a fan box and a first air duct; the machine body is arranged below the fan box, the first air duct is arranged in the fan box and is used for communicating the machine body with the fan box; and the machine body and the first air duct are arranged in an accommodating groove formed in an installation wall. By hiding the machine body and the first air duct in the accommodating groove formed in the installation wall, the space on the rear side of the fan box is equivalent to being extended by a certain size compared with a conventional low-suction extractor hood, that is, the space of the air duct on the side of the fan inlet is larger under the condition that the size of the fan box is the same as that of the conventional low-suction extractor hood, so that the oil fume extraction effect can be effectively improved.
