[0035] In the range hood, the range hood further comprises a driving assembly 3, the driving assembly 3 is arranged in the telescopic inner cavity 13 and is used for driving the telescopic panel assembly 2 to slide in the telescopic inner cavity 13. When the range hood is started, the driving assembly 3 drives the telescopic panel assembly 2 to extend out of the telescopic inner cavity 13, so that the functional devices in the mounting cavity extend out of the telescopic inner cavity 13 and are normally used, so as to achieve the effect of assisting the user in cooking or other functions. When the range hood is turned off, the driving assembly 3 drives the telescopic panel assembly 2 to retract into the telescopic inner cavity 13, so as to reduce the occupation of the kitchen space by the telescopic panel assembly 2 when the range hood is in an idle state.

[0036] In the range hood, as shown in the drawings, Figures 5 to 7 The driving assembly 3 comprises a driving motor 31, a driving gear 32, a rack 33 and a panel connecting piece 34, the driving gear 32 is connected to the output end of the driving motor 31, the driving gear 32 is engaged with the rack 33, the rack 33 is connected to the panel connecting piece 34, and the panel connecting piece 34 is connected to the telescopic panel assembly 13.

Specifically, the panel connectors 34 are fixedly connected to the telescopic panel assembly 13 and the slide bars 36. The drive motor 31 drives the drive gear 32 to rotate, driving the racks 33 to move, thereby moving the telescopic panel assembly 13 connected to the racks 33 through the panel connectors 34. The slide bars 36 are slidably connected within the slide rails 35, indirectly guiding the telescopic panel assembly 13 to extend or retract into the telescopic inner cavity 13 through the slide rails 35, thereby making the telescopic panel assembly 13 more smooth and the movement path more stable.

[0038] In the range hood of the present invention, the functional devices include an air curtain assembly and / or an air quality detection module and / or a lighting module. The top plate of the telescopic panel assembly 2 is provided with an air curtain suction port 21 and / or a detection hole 22, and the bottom plate of the telescopic panel assembly 2 is provided with an air curtain outlet 23 and / or a lighting window 24. The air curtain assembly draws air through the air curtain suction port 21 and exhausts air through the air curtain outlet 23, or / and the air above the telescopic panel assembly 2 enters the air quality detection module through the detection hole 133 and is detected by the air quality detection module, or / and the light-emitting side of the lighting module faces the lighting window 24.

[0039] In the embodiment, the functional device comprises a curtain air assembly, an air quality detection module and an illumination module, the top plate 12 of the telescopic panel assembly 2 is provided with a curtain air suction port 21 and a detection hole 22, the bottom plate of the telescopic panel assembly 2 is provided with a curtain air outlet 23 and an illumination window 24, the curtain air assembly sucks air through the curtain air suction port 21 and discharges air through the curtain air outlet 23, air above the telescopic panel assembly 2 enters the air quality detection module and is detected by the air quality detection module through the detection hole 22, and the light-emitting side of the illumination module faces the illumination window 24. When the telescopic panel assembly 2 is extended out of the telescopic inner cavity 13, the illumination assembly, the curtain air assembly and the air quality detection module are extended out of the telescopic inner cavity 13 with the telescopic panel assembly 2, and when the smoke machine is turned off, the telescopic panel assembly 2 is retracted into the telescopic inner cavity 13, so that the telescopic panel assembly 2 is hidden. When the smoke machine is started, the illumination assembly, the curtain air assembly and the air quality detection module are operated according to the setting or user selection, and the functional part can make the curtain air module and the illumination module play a function. When the curtain air assembly is started, air above the telescopic panel assembly 2 enters through the curtain air inlet hole and is discharged by the curtain air assembly through the curtain air outlet hole, so as to form a curtain air below the bottom plate of the telescopic panel assembly 2, the curtain air is located between the user and the stove, and can block the oil fume to avoid the escape of the oil fume. When the illumination assembly is operated, the light emitted by the illumination assembly is irradiated downward through the illumination window 24, so as to provide an illumination environment for the user. When the air quality detection module is started, air above the telescopic panel assembly 2 enters the air quality detection module through the detection hole 22 and is detected by the air quality detection module, the air quality detected by the air quality detection module represents the air quality in the kitchen, when the smoke machine is operated, the air quality detection module can detect the suction effect of the smoke machine on the oil fume, and when the smoke machine is turned off, the air quality detection module can play a cruise role to detect whether the oil fume backflows in the kitchen.

[0040] As shown in the smoke machine of the utility model, Figure 10 and Figure 11 The number of top suction air inlets is two groups, and the two groups of top suction air inlets are symmetrically arranged on the left and right sides of the top plate 12. One group of top suction air inlets is arranged on the left side and the right side of the top plate 12 of the smoke machine, so that the air suction range of the left side and the right side of the top plate 12 is enhanced. The two groups of top suction air inlets are symmetrically arranged, which can improve the appearance integrity of the top plate 12 and reasonably arrange the distribution positions of the top suction air inlets, so as to ensure that the oil fume flowing to the top plate 12 is fully sucked into the smoke collecting cavity.

[0041] As shown in the smoke machine of the utility model, Figure 4As shown, each group of top suction ports includes a second suction port 121 and a third suction port 122, which are arranged along the width direction of the top plate 12, the length of the second suction port 121 is less than that of the third suction port 122, and the second suction port 121 is located at the rear side of the third suction port 122. After the oil fume flows to the top plate 12, the oil fume flowing forward first flows through the second suction port 121, part of the oil fume is sucked into the smoke collecting cavity by the second suction port 121, and the oil fume that cannot be sucked by the second suction port 121 continues to flow forward and is finally sucked into the smoke collecting cavity by the third suction port 122, so that the oil fume escaping can be further reduced, and the suction effect of the range hood on the oil fume can be further improved. The length of the second suction port 121 is less than that of the third suction port 122 and is located at the rear side of the third suction port 122, which is equivalent to increasing the suction area of the part corresponding to the left end of the top plate 12 and the part corresponding to the right end of the top plate 12 of the third suction port 122, thereby reducing the oil fume escaping to the left and right sides of the top plate 12, and improving the suction effect of the range hood on the oil fume.

[0042] In the range hood of the utility model, as shown in the figure, Figure 4 The left side edge of the second suction port 121 of the left top suction port is aligned with the left side edge of the third suction port 122, and the right side edge of the second suction port 121 of the right top suction port is aligned with the right side edge of the third suction port 122. Since the length of the third suction port 122 is greater than that of the second suction port 121, the two ends of the third suction port 122 close to each other can be close to the middle part of the top plate 12 along the left and right directions, so that the appearance integrity of the range hood body 1 can be improved, and the distribution positions of the second suction port 121 and the third suction port 122 can be reasonably arranged to ensure that the oil fume flowing to the top plate 12 is fully sucked into the smoke collecting cavity.

[0043] In the range hood of the utility model, as shown in the figure, Figure 4 The distance between the left side edge of the left top suction port and the right side edge of the right top suction port is not less than the width of the first suction port 111. The distance between the left side edge of the left top suction port and the left side edge of the top plate 12 is not greater than the distance between the left side edge of the first suction port 111 and the left side edge of the front panel 11, and the distance between the right side edge of the right top suction port and the right side edge of the top plate 12 is not greater than the distance between the right side edge of the first suction port 111 and the right side edge of the front panel 11. When the oil fume enters the smoke collecting cavity through the first suction port 111, part of the oil fume escapes through the two sides of the first suction port 111 and is sucked by the top suction ports on the upper left and right sides, so that the purification effect of the range hood on the oil fume can be improved.

[0044] In the range hood of the utility model, as shown in the figure, Figure 4As shown, the distance between the right side edge of the left top air inlet and the left side edge of the right top air inlet is not greater than the width of the first air inlet 111. In this way, the left top air inlet and the right top air inlet can be guaranteed to overlap with the first air inlet 111 in the flow path of the oil fume, so that the oil fume that is not sucked into the smoke collecting cavity by the first air inlet 111 can be sucked into the smoke collecting cavity by the left and right top air inlets after flowing to the top plate 12, thereby further reducing the escape of the oil fume and improving the suction effect of the range hood on the oil fume.

[0045] In the range hood of the utility model, as shown in Figure 11 As shown, each group of top air inlets includes a plurality of second air inlets 121, and the second air inlets 121 in the same group of top air inlets are arranged in a plurality of rows in the front-rear direction of the top plate 12, and each second air inlet 121 extends in the left-right direction of the top plate 12. For example, the total number of second air inlets 121 can be 6, and the 6 second air inlets 121 are distributed in two groups of three rows, that is, there are 3 second air inlets 121 in each group of top air inlets, and the 3 second air inlets 121 are divided into 3 rows in the front-rear direction. The second air inlets 121 are divided into two groups and arranged on the left side and the right side of the top plate 12 of the range hood, thereby enhancing the air suction range of the left side and the right side of the top plate 12.

[0046] When the range hood is working, the oil fume that is not sucked by the first air inlet 111 will flow upward along the front panel 11, and after flowing to the top plate 12, the oil fume will flow towards the front side and the left and right sides, and finally can be sucked into the smoke collecting cavity by the second air inlets 121; the oil fume flowing towards the front can be sucked by the second air inlets 121 in the front row even if it is not sucked by the second air inlets 121 in the rear row during the continuous flow. In this way, the oil fume flowing through the range hood body 1 can be fully sucked into the smoke collecting cavity, thereby reducing the escape of the oil fume and improving the suction effect of the range hood on the oil fume, and improving the user experience.

[0047] In the range hood of the utility model, as shown in Figure 10 and Figure 11 As shown, the range hood body 1 further includes a side baffle assembly 14 arranged on the left and right sides of the range hood body 1. The side baffle assembly 14 includes two side baffles arranged on the left and right sides of the range hood body 1, respectively. Among them, the top side edge of the side baffle is connected with the top plate 12, the rear side edge of the side baffle is connected with the front panel 11, and the connection between the top side edge and the rear side edge of the side baffle is connected with the connection between the front panel 11 and the top plate 12. The part of the oil fume that is not sucked by the first air inlet 111 will be divided into two parts towards the left and right sides of the front panel 11, and the oil fume flowing towards the left and right sides will be blocked by the side baffles, thereby avoiding the oil fume from easily diffusing away from the range hood body 1, prolonging the residence time of the oil fume near the front panel 11 and the top plate 12, and enabling the oil fume to be more fully sucked into the smoke collecting cavity by the first air inlet 111. In this way, the escape of the oil fume can be reduced, thereby improving the suction effect of the range hood on the oil fume and improving the user experience.

[0048] The above merely preferred embodiments of the present application are not used to limit the present application, any modification, equivalent replacement or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
