[0041] In the related art, by controlling the movement of the guide plate, the opening and closing of the air inlet of the range hood and the change of the size of the air inlet gap can be controlled, but the change of the smoke suction mode of the range hood cannot be realized, and different use environments cannot be adapted.

[0042] The embodiments of the present application provide a range hood, please refer to Figures 1 to 6 , comprising a body 10, a movement assembly 20 and a guide plate assembly 30.

[0043] The body 10 of the range hood is internally provided with a gas suction device and an air duct for discharging oil fume, and the bottom of the body 10 is constructed with an air inlet 11. The gas suction device reduces the air pressure at the air inlet 11, so that the oil fume can be discharged outdoors along the air inlet 11.

[0044] The air inlet 11 is arranged at the bottom of the body 10. In the absence of shielding, the high-temperature oil fume enters the air inlet 11 below the center position of the air inlet 11, that is, the oil fume is discharged by top suction mode.

[0045] The gas suction device and the air duct structure inside the body 10 can be designed as needed, which can discharge the oil fume outdoors, and is not limited here.

[0046] The movement assembly 20 is installed on the body 10, and the movement assembly 20 can change the position of the guide plate assembly 30.

[0047] In one embodiment, the moving assembly 20 is arranged near the air inlet 11 of the machine body 10, which can reduce the overall size of the range hood and make the range hood more compact.

[0048] The deflector plate assembly 30 is horizontally arranged below the air inlet 11 and connected to the moving assembly 20. The moving assembly 20 can change the position of the deflector plate assembly 30 relative to the air inlet 11, so that the deflector plate assembly 30 can be switched between the avoidance position and the shielding position.

[0049] In the avoidance position, the deflector plate assembly 30 avoids the central position of the air inlet 11, so that the deflector plate assembly 30 does not block the high-temperature oil fume rising below to the air inlet 11, and the oil fume is discharged outdoors in the top suction mode. The noise during the oil fume discharge process is small, and the smoke discharge rate is high.

[0050] In the shielding position, the deflector plate assembly 30 is located below the central position of the air inlet 11, so that the oil fume rising to the deflector plate assembly 30 is shielded, and the oil fume cannot directly enter the air inlet 11. At this time, the position between the side of the deflector plate assembly 30 and the machine body 10 is open, and the air inlet 11 is in communication with the outside along the side of the deflector plate assembly 30. The oil fume enters the air inlet 11 along the side of the deflector plate assembly 30, and is discharged outdoors in the side suction mode. The covering area during the oil fume discharge process is large, and the oil fume discharge efficiency is high, which can create a zero-oil-fume kitchen environment.

[0051] The range hood provided by the embodiment of the present application can switch between the top suction mode and the side suction mode through the linkage of the moving assembly 20 and the deflector plate assembly 30, so as to adapt to different use environments.

[0052] According to one embodiment of the present application, the moving assembly 20 includes a first end and a second end moving in opposite directions, and the deflector plate assembly 30 includes a first deflector plate assembly and a second deflector plate assembly.

[0053] The first deflector plate assembly is hinged to the first end of the moving assembly 20, and the second deflector plate assembly is hinged to the second end of the moving assembly 20. The first deflector plate assembly and the second deflector plate assembly are symmetrically arranged below the air inlet 11.

[0054] When the moving assembly 20 works, the first deflector plate assembly and the second deflector plate assembly can be simultaneously close to or away from each other.

[0055] In the avoidance position, the moving assembly 20 makes the first deflector plate assembly and the second deflector plate assembly away from each other, and the gap between the first deflector plate assembly and the second deflector plate assembly avoids the central position of the air inlet 11, so that the oil fume can be discharged outdoors along the central position of the air inlet 11.

[0056] In the shielding position, the movement assembly 20 makes the first deflector assembly and the second deflector assembly contact each other, and the first deflector assembly and the second deflector assembly are located below the center of the air inlet 11 together, so that the oil fume can enter the air inlet 11 along the side of the first deflector assembly and the second deflector assembly.

[0057] In an embodiment, the movement assembly 20 can be two independent movement devices, and the positions of the first deflector assembly and the second deflector assembly are adjusted respectively when the position of the deflector assembly 30 is adjusted.

[0058] It should be noted that the first deflector assembly and the second deflector assembly can be moved simultaneously or in sequence when the positions of the first deflector assembly and the second deflector assembly are adjusted.

[0059] According to an embodiment of the present application, the range hood further comprises a support assembly 40, and the movement assembly 20 is installed on the support assembly 40.

[0060] The support assembly 40 provides a stable mounting position for the movement assembly 20, which is conducive to ensuring the stability of the deflector assembly 30 during movement.

[0061] The support assembly 40 is further provided with a sliding device 50, and the deflector assembly 30 is connected to the support assembly 40 through the sliding device 50. The sliding device 50 can make the first deflector assembly and the second deflector assembly move horizontally. In an embodiment, the sliding device 50 comprises a sliding rail 51 and a sliding piece 52 slidingly connected to the sliding rail 51, and one of the sliding rail 51 and the sliding piece 52 is connected to the support assembly 40, and the other is connected to the deflector assembly 30.

[0062] The deflector assembly 30 is constrained by the sliding device 50 during movement, so that the position accuracy is high and the operation is stable.

[0063] In an embodiment, the sliding device 50 adopts a ball sliding rail, and the resistance and noise of the deflector assembly 30 during movement along the ball sliding rail are small.

[0064] The movement assembly 20 can drive the deflector assembly 30 to switch between the avoiding position and the shielding position, so as to change the smoke suction mode of the range hood to adapt to different use environments.

[0065] According to an embodiment of the present application, the movement assembly 20 comprises a driving device 21, a driving rod 22, a first curved arm 23, and a second curved arm 24.

[0066] The driving device 21 is installed on the support assembly 40, and the driving device 21 is used to drive the rotation of the driving rod 22.

[0067] The driving rod 22 comprises a first movement end and a second movement end arranged oppositely, and the center of the extension direction of the driving rod 22 is connected to the driving device 21. When the driving device 21 rotates, the opposite ends of the driving rod 22 move reversely.

[0068] The two ends of the first curved arm 23 are respectively hinged to the first driving end and the first guide plate assembly, and the two ends of the second curved arm 24 are respectively hinged to the second driving end and the second guide plate assembly. When the driving rod 22 rotates, the first curved arm 23 and the second curved arm 24 move reversely at the same time, so that the first guide plate assembly and the second guide plate assembly can approach or move away at the same time.

[0069] It should be noted that the driving device 21 can adopt a motor or a swing cylinder.

[0070] When the driving device 21 is a motor, the rotation direction and rotation angle of the motor are controlled, so that the driving rod 22 rotates, the first movement end and the second movement end of the driving rod 22 move reversely, and the first guide plate assembly and the second guide plate assembly can approach or move away at the same time.

[0071] In an embodiment, the motor is connected with a speed reducer, and the speed reducer can change the rotation direction and rotation torque of the motor. When the speed reducer is adopted, a motor with smaller power can be adopted, so that the energy consumption of the range hood is reduced.

[0072] When the driving device 21 is a swing cylinder, the swing direction and swing amplitude of the swing cylinder are controlled, so that the driving rod 22 rotates, and then the first guide plate assembly and the second guide plate assembly can approach or move away at the same time.

[0073] In an embodiment, a strip-shaped hole is arranged at the center of the extension direction of the driving rod 22, and the driving shaft of the driving device 21 is a prism structure. When the driving shaft is inserted into the strip-shaped hole, the driving rod 22 and the driving device 21 will not slide relatively, so that the movement precision is improved.

[0074] In an embodiment, the guide plate assembly 30 is hinged to the first curved arm 23 or the second curved arm 24 by using an elastic pin, so that the installation and disassembly are relatively convenient.

[0075] In another embodiment, the driving device 21 is connected to the guide plate assembly 30 through a gear structure, and the guide plate assembly 30 is driven to move through the rotation of the gear.

[0076] When the guide plate assembly 30 switches between the avoiding position and the shielding position, it can move below the air inlet 11. Due to the size limitation of the body 10, the movement distance of the guide plate assembly 30 is limited.

[0077] According to one embodiment of the present application, the movement assembly 20 further comprises a limiting structure 25 for limiting the stroke of the driving rod 22.

[0078] When the movement assembly 20 works, the driving device 21 drives the driving rod 22 to rotate, and the swinging distance of the driving rod 22 will determine the movement distance of the deflector plate assembly 30.

[0079] The limiting structure 25 can limit the swinging range of the driving rod 22, and further limit the movement distance of the deflector plate assembly 30, so as to avoid the collision between the deflector plate assembly 30 and the machine body 10, and improve the safety of the structure.

[0080] In one embodiment, the movement stroke of the first deflector plate assembly and the second deflector plate assembly is between 33mm and 37mm.

[0081] It can be understood that the movement stroke of the first deflector plate assembly and the second deflector plate assembly can be adjusted according to the size of the range hood.

[0082] In one embodiment, the support assembly 40 comprises a support 41 and a mounting seat 42, the mounting seat 42 is arranged on the support 41, and the driving device 21 is connected to the mounting seat 42.

[0083] The driving device 21 is fixed on the support 41 through the mounting seat 42, and the mounting seat 42 improves the position stability of the driving device 21 during work, so as to avoid the noise of the driving device 21 during work.

[0084] When the support 41 and the first curved arm 23 or the second curved arm 24 intersect, a avoiding slot is arranged on the support 41, and the first curved arm 23 or the second curved arm 24 is inserted in the avoiding slot. When the movement assembly 20 moves, the support 41 will not hinder the movement of the first curved arm 23 or the second curved arm 24.

[0085] When the position of the deflector plate assembly 30 is adjusted, the smoke suction mode of the range hood can be changed to adapt to different use environments.

[0086] According to one embodiment of the present application, the first deflector plate assembly and the second deflector plate assembly each comprise a deflector plate 31 and a first support 32.

[0087] The deflector plate 31 can adopt a stainless steel panel or a glass panel, and is arranged below the machine body 10. The first support 32 is connected to the deflector plate 31 and the movement assembly 20, and can drive the deflector plate 31 to move horizontally.

[0088] In one embodiment, the first support 32 comprises a panel connecting part, the panel connecting part has a certain length and width, and the structure is relatively stable when the panel connecting part is adhered to the deflector plate 31.

[0089] According to one embodiment of the present application, the first and second deflector assemblies further comprise a second support 33, which is arranged between the moving assembly 20 and the first support 32, and the first support 32 is hinged to the second support 33.

[0090] The first support 32 is provided with a sliding groove 34 at one end away from the second support 33, and the sliding groove 34 is connected to the machine body 10 through a pulley assembly 35.

[0091] The first support 32 is hinged to the second support 33, and the deflector 31 can rotate along the second support 33, which reduces the difficulty of assembling the deflector 31.

[0092] The first support 32 is provided with a sliding groove 34 at one end away from the second support 33, and the sliding groove 34 is connected to the machine body 10 through a pulley assembly 35.

[0093] The sliding groove 34 has a certain size, and the pulley assembly 35 can move in the sliding groove 34, and the pulley assembly 35 can cooperate with the position adjustment of the deflector 31.

[0094] When assembling the deflector assembly 30, first install the deflector 31 on the first support 32, and then hinge it to the second support 33. After adjusting the deflector 31 to be in a horizontal state, insert the pulley assembly 35 into the sliding groove 34, and finally fix the pulley assembly 35 to the machine body 10, thereby completing the installation of the deflector assembly 30.

[0095] The bottom of the machine body 10 is provided with an air inlet 11, and the position of the deflector assembly 30 can be adjusted to change the smoke suction mode of the range hood.

[0096] According to one embodiment of the present application, the machine body 10 is formed with a smoke gathering cavity 12 at the air inlet 11, and the size of the smoke gathering cavity 12 gradually increases away from the air inlet 11.

[0097] The inner wall of the smoke gathering cavity 12 is inclined outward to form a horn-shaped opening structure, and the area of the opening is larger, which helps the oil fume to flow into the air inlet 11.

[0098] In the side suction mode, the deflector assembly 30 is located below the center position of the air inlet 11, and the inner wall of the smoke gathering cavity 12 forms an oil fume channel with the side of the deflector assembly 30. The inclined inner wall increases the area of the smoke gathering, and improves the efficiency of the range hood in discharging oil fume.

[0099] In summary, the range hood provided by the embodiment of the application comprises a body 10, a moving assembly 20 and a deflector assembly 30. The bottom of the body 10 is configured with an air inlet 11, and the oil fume in the kitchen is discharged outdoors along the air inlet 11. The moving assembly 20 is connected to the body 10 and the deflector assembly 30, and the deflector assembly 30 is horizontally arranged below the air inlet 11. The moving assembly 20 can change the position of the deflector assembly 30 relative to the air inlet 11, so that the deflector assembly 30 is switched between an avoiding position and a shielding position. In the avoiding position, the deflector assembly 30 avoids the central position of the air inlet 11, the air inlet 11 inhales along the central position, and the oil fume is discharged outdoors in a top suction mode. In the shielding position, the deflector assembly 30 is located below the central position of the air inlet 11, and the oil fume enters the air inlet 11 from the side of the deflector assembly 30, and the oil fume is discharged outdoors in a side suction mode. The range hood can be switched between the top suction mode and the side suction mode under the joint action of the moving assembly 20 and the deflector assembly 30, so as to adapt to different use environments.

[0100] In the case that the smoke collection cavity 12 is arranged at the air inlet 11, the smoke collection area of the range hood is large, the efficiency is high, and the oil fume in the kitchen can be quickly discharged.

[0101] When the high-temperature oil fume rises to the smoke collection cavity 12, it is blocked by the inner wall of the smoke collection cavity 12, and the oil fume will not spread to the surrounding area, avoiding the spread of the oil fume to other areas in the kitchen.

[0102] The smoke collection cavity 12 forms a horn-shaped structure, and the inner wall arranged obliquely reduces the resistance when the oil fume is sucked from the side, which helps the oil fume to flow smoothly to the air inlet 11.

[0103] When the deflector assembly 30 comprises a first deflector assembly and a second deflector assembly, the first deflector assembly and the second deflector assembly are symmetrically arranged.

[0104] When the first deflector assembly and the second deflector assembly are away from each other at the same time, there is a gap between them, which can avoid the central position of the air inlet 11.

[0105] When the first deflector assembly and the second deflector assembly are in contact, the oil fume can be blocked from entering the air inlet 11 along the central position. At this time, the air inlet 11 is connected to the air in the kitchen through the side of the deflector assembly 30, and the oil fume is discharged outdoors in a side suction mode.

[0106] The above only describes the preferred embodiments of the application and is not intended to limit the application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the application shall be included in the protection scope of the application.
