UTILITY MODEL CONTENTS

[0005] The utility model solves the technical problems existing in the prior art, provides an oil fume extractor, which does not occupy the space above the stove, is not hit when the pot is overturned, and is easy to clean.

[0006] The utility model adopts the technical scheme that an oil fume extractor includes an air inlet assembly and a smoke baffle assembly, the air inlet assembly includes a first box body and a second box body arranged on the inner side of the first box body, the second box body is provided with an air inlet on the upper side, the second box body can be lifted relative to the first box body, the second box body can be in a first position in which the air inlet is exposed to the first box body and a second position in which the air inlet is hidden in the first box body, the smoke baffle assembly includes a smoke baffle arranged on the front side of the first box body, and the smoke baffle can be lifted relative to the first box body, so that the smoke baffle can be in a third position when the air inlet is in the first position and a fourth position when the air inlet is in the second position, and the third position is lower than the fourth position.

[0007] By setting the smoke baffle assembly to be liftable, the smoke baffle can be lifted to a suitable height when the pot is overturned, so as to prevent the smoke baffle from being hit. When the range hood is in a non-working state, the smoke baffle is located on the upper front side of the first cabinet. Since the smoke baffle itself is relatively thin in thickness, and the upper front and rear space itself has a fan frame and a storage cabinet, the smoke baffle placed on the upper side basically does not occupy too much space on the upper side, so as to ensure the space size of the front side of the first cabinet as a whole, improve the space utilization rate, and relatively to the range hood with a fixed smoke baffle structure, the range hood is more simple in appearance and has fewer cleaning dead angles.

[0008] In order to drive the smoke baffle assembly to lift, the range hood further comprises a moving mechanism arranged on the inner side of the first cabinet and used for driving the smoke baffle assembly to lift, and the smoke baffle assembly further comprises a connecting piece used for connecting the smoke baffle and the moving mechanism.

[0009] In order to enable the connecting piece to lift on the first cabinet, the connecting piece is arranged on the left and right sides of the smoke baffle respectively, and the left and right sides of the first cabinet are respectively provided with first sliding grooves for the connecting piece to lift.

[0010] In order to enable the connecting piece to lift on the first cabinet, the connecting piece is arranged on the left and right sides of the smoke baffle respectively, and the left and right sides of the rear side of the first cabinet are respectively provided with first sliding grooves for the connecting piece to lift.

[0011] In order to monitor the height of the pot, the range hood further comprises a sensor arranged on the smoke baffle assembly and capable of sensing the distance of the pot below.

[0012] In order to better realize the storage function on the smoke baffle, the smoke baffle is parallel to the horizontal plane.

[0013] In order to facilitate the arrangement of the fan, a fan frame for arranging the fan is arranged above the air inlet assembly.

[0014] Further, when the second cabinet is in the second position, the lower edge of the air inlet is not lower than the lower edge of the first cabinet in the vertical projection from front to back, so as to ensure that the air inlet can be completely shielded by the front side of the first cabinet in the non-working state of the range hood, and reduce the problem of smoke smell caused by the oil smoke in the flue.

[0015] Compared with the prior art, the range hood has the following advantages:

[0016] By setting the smoke baffle assembly to be liftable, the smoke baffle can be lifted to a suitable height when the pot is being stirred, so as to prevent the smoke baffle from being hit. When the range hood is in a non-working state, the smoke baffle is located on the upper front side of the first box body. Since the smoke baffle itself is relatively thin in thickness, and the upper front and rear space itself has a fan frame and a storage cabinet, the smoke baffle placed on the upper side basically does not occupy too much space on the upper side, so as to ensure the space size of the front side of the first box body, improve the space utilization rate, and relatively, the range hood with the fixed smoke baffle structure is more simple in appearance and has fewer cleaning dead angles.

[0017] By setting the sensor on the smoke baffle, when the pot is detected to move up and down, the smoke baffle can be lifted synchronously, so as to avoid the smoke baffle from being hit when the pot is stirred. The smoke baffle and the air inlet can be synchronously linked. When the user operates with a small amplitude, the smoke baffle is close to the lower side of the first box body, at this time, the air inlet is large, and since the negative pressure of the smoke baffle is expanded outward, the oil fume suction effect at this time is ensured. When the user operates with a large amplitude, the smoke baffle and the air inlet are both moved upward, at this time, since the distance between the smoke baffle and the lower edge of the first box body is relatively far, the negative pressure outward expansion effect is reduced, but since the air inlet is moved upward, the air inlet area of the air inlet is reduced, and the negative pressure is enhanced, so as to ensure the oil fume suction effect at this time. The linkage coupling of the smoke baffle and the air inlet can more effectively ensure the oil fume suction effect. BRIEF DESCRIPTION OF DRAWINGS

[0025] Embodiment one

[0026] Referring to Figs. 1-2 An extractor hood comprises a fan frame 1 and an air inlet assembly arranged below the fan frame 1. The fan frame 1 is arranged to accommodate a fan, and the air inlet assembly comprises a first box body 21 and a second box body 22 arranged inside the first box body 21. The front side of the second box body 22 is provided with an air inlet 221. The second box body 22 is capable of ascending and descending relative to the first box body 21, and the second box body 22 can be in a first position of downward movement to expose the air inlet 221 out of the first box body 21, and a second position of upward movement to hide the air inlet 221 in the first box body 21.

[0027] When the extractor hood is in a working state, the air inlet 221 is lowered to expose the first box body 21, in the first position, to meet the functional requirements of the extractor hood; when the extractor hood is in a non-working state, the air inlet 221 is moved upward to the inside of the first box body 21, in the second position, and from the front to the rear direction, the lower edge of the air inlet 221 is not lower than the lower edge of the first box body 21, so as to ensure that the air inlet 221 can be completely shielded by the front side of the first box body 21 in the non-working state of the extractor hood, and the structure of the air inlet 221 is open on the front side, and the left and right sides, the rear side and the bottom are all connected with the surrounding plate structure, and the front side and the inner wall of the first box body 21 have a small movement gap, so as to ensure the relative sealing of the air inlet 221 and reduce the problem of smoke backflow and odor caused by oil smoke in the flue.

[0028] The range hood further comprises a baffle plate assembly 3 and a moving mechanism for driving the baffle plate assembly 3 to move up and down, the baffle plate assembly 3 being capable of moving up and down relative to the first cabinet 21 so as to be in a third position and a fourth position, the baffle plate 31 being in the third position when the air inlet 221 is in the first position, and the baffle plate 31 being in the fourth position when the air inlet 221 is in the second position, and the third position being lower than the fourth position.

[0029] The baffle plate assembly 3 comprises a baffle plate 31 arranged at the front side of the first cabinet 21 and a connecting piece 32 for connecting the baffle plate 31 with the moving mechanism. The baffle plate 31 plays a role of gathering smoke in a working state and facilitates the oil fume to enter the air inlet 221, and can be arranged at the front side of the first cabinet 21 in a manner parallel to the horizontal plane (allowing a certain error due to installation or manufacturing process, such as having a tilt of ±10° relative to the horizontal plane), so as to ensure that the object placed will not slide by itself and meet the object placing requirement. The connecting piece 32 is arranged at the left and right sides of the baffle plate 31 respectively, and the first cabinet 21 is provided with first sliding grooves 211 for the connecting piece 32 to move up and down, and the connecting piece 32 and the first sliding grooves 211 are in sliding fit. The moving mechanism is not shown in the figure, and is arranged inside the first cabinet 21, and the connecting piece 32 passes through the first sliding grooves 211 and is in transmission connection with the moving mechanism.

[0030] When the range hood is in a non-working state, the baffle plate 31 is located at the upper part of the front side of the first cabinet 21 (the fourth position), and since the baffle plate 31 itself is relatively thin in thickness, and the upper part has the fan frame 1 and the object placing cabinet, the baffle plate 31 placed at the upper side will not occupy much space at the upper part, so as to ensure the space size of the front side of the first cabinet 21, improve the space utilization, and relative to the range hood provided with a fixed baffle plate structure, the range hood is more simple in appearance and has fewer cleaning dead angles.

[0031] The range hood further comprises a sensor 4 arranged on the baffle plate assembly 3 and capable of sensing the distance of the lower pot.

[0032] In this embodiment, the sensor 4 is arranged at the bottom of the smoke baffle 31, and when the movement of the pot is detected, the smoke baffle 31 can be lifted synchronously to avoid the pot from touching the smoke baffle 31 when the pot is being turned upside down. The smoke baffle 31 and the air inlet 221 can be coupled synchronously. When the user operates with a small amplitude, the smoke baffle 31 is close to the lower side of the first cabinet 21, and at this time, the air inlet 221 is large, and due to the negative pressure expansion effect of the smoke baffle 31, the oil fume extraction effect at this time is ensured. When the user operates with a large amplitude, the smoke baffle 31 and the air inlet 221 are both lifted, and at this time, due to the relatively large distance between the smoke baffle 31 and the lower edge of the first cabinet 21, the negative pressure expansion effect is reduced, but due to the lifting of the air inlet 221, the air inlet area of the air inlet 221 is reduced, and the negative pressure is increased, thereby ensuring the oil fume extraction effect at this time. The linkage coupling of the smoke baffle 31 and the air inlet 221 can more effectively ensure the oil fume extraction effect. In order to realize the linkage coupling of the smoke baffle assembly 3 and the second cabinet 22, the two can adopt the same movement mechanism, or can be controlled to realize synchronous lifting.

[0033] Embodiment two

[0034] Referring to Figs. 3-5 The difference between this embodiment and the above-mentioned embodiments is that the left and right sides of the rear side of the first cabinet 21 are respectively provided with a second sliding groove 212 for the lifting of the connecting piece 32, thereby replacing the first sliding groove 211. The connecting piece 32 extends through the left and right sides of the first cabinet 21, is bent, and passes through the second sliding groove 212.

[0035] The second sliding groove 212 is arranged at the rear side of the first cabinet, thereby ensuring the integrity of the side of the first cabinet and being more beautiful.
