An air inlet 112 is provided on an air inlet surface 111 of the smoke collecting hood 11 facing the cooker, and the guide member 13 is arranged between the smoke baffle 12 and the first area of ​​the air inlet surface 111, so that the smoke baffle 12 is slidably connected with the air inlet surface 111, and the smoke baffle 12 is used to adjust the size of the air inlet 112; a first stopper 14 is connected with the air inlet surface 111 and arranged on the moving path of the smoke baffle 12, and the first stopper 14 is used to abut against the smoke baffle 12; wherein the first area is an area on the air inlet surface 111 close to the air inlet 112.

The above structure improves the stability and reliability of the movement of the smoke baffle 12. In addition, the smoke baffle 12 can be limited by the first limiting member 14 to prevent the smoke baffle 12 from moving beyond the range of the guide member 13.

[0061] See also Figures 2 to 7 It is understood that the guide member 13 includes a sliding portion 131 and a first guide portion 132, the sliding portion 131 and the first guide portion 132 are slidably matched, the first guide portion 132 is arranged on the air inlet surface 111, and the sliding portion 131 is arranged on the smoke damper 12; for the extension direction of the sliding portion 131 and the first guide portion 132, there can be the following implementation modes, in a first implementation mode, the extension direction of the sliding portion 131 is the moving direction of the smoke damper 12; in a second implementation mode, the extension direction of the first guide portion 132 is the moving direction of the smoke damper 12; in a third implementation mode, the extension directions of the sliding portion 131 and the first guide portion 132 are both the moving directions of the smoke damper 12. In this embodiment, the extending direction of the sliding part 131 is the moving direction of the smoke shield 12, so that the sliding connection between the smoke shield 12 and the air inlet surface 111 is realized through the sliding cooperation of the sliding part 131 and the first guide part 132, and then the size of the air inlet 112 on the air inlet surface 111 can be adjusted by sliding the smoke shield 12 relative to the air inlet surface 111, so that the size of the air inlet 112 can match the amount of oil smoke generated. With the above-mentioned structural form, through the cooperation of the sliding part 131 and the first guide part 132, the first guide part 132 can provide guidance for the movement of the sliding part 131, so that the sliding part 131 can move according to a certain preset path, thereby improving the stability and reliability of the movement of the smoke shield 12.

[0062] like Figure 6 and Figure 7As shown, one of the sliding part 131 and the smoke shield 12 has a slot 134, and the other is engaged in the slot 134, so that the sliding part 131 is connected to the smoke shield 12. In addition, by adopting the above structure, if one of the sliding part 131 and the smoke shield 12 is damaged, only the damaged sliding part 131 and the smoke shield 12 need to be replaced, and the sliding part 131 and the smoke shield 12 can be used normally, which reduces the use cost.

[0063] like Figures 5 to 7 As shown, the range hood 1 further includes a second stopper 15, and the second stopper 15 can be implemented in the following ways. In the first way, the sliding part 131 is connected to the second stopper 15, and the second stopper 15 is used to limit the sliding part 131 or the smoke baffle 12 disposed in the slot 134 from moving in the slot 134; in the second way, the smoke baffle 12 is connected to the second stopper 15, and the second stopper 15 is used to limit the sliding part 131 or the smoke baffle 12 disposed in the slot 134 from moving in the slot 134; in the third way, the sliding part 131 and the smoke baffle 12 are both connected to the second stopper 15, and the second stopper 15 is used to limit the sliding part 131 or the smoke baffle 12 disposed in the slot 134 from moving in the slot 134. With the above-mentioned structural form, the second limiting member 15 can prevent the sliding portion 131 and the smoke baffle 12 from being separated, thereby improving the stability and reliability of the connection between the sliding portion 131 and the smoke baffle 12 .

[0064] It should be noted that, in this embodiment, a slot 134 is provided on the sliding portion 131, and the smoke shield 12 is engaged in the slot 134. The second stopper 15 is provided on the sliding portion 131, and is located at the opening of the slot 134 and abuts against the smoke shield 12, so as to prevent the smoke shield 12 from moving along the extending direction of the slot 134 and escaping from the slot 134. In order to prevent the smoke shield 12 from escaping from the slot 134 along the extending direction perpendicular to the slot 134, the second stopper 15 is preferably provided at one end of the smoke shield 12 extending out of the slot 134, and the second stopper 15 abuts against the surface of the slot 134.

[0065] See also Figure 6 and Figure 7It is understood that the guide member 13 also includes a second guide portion 133, the second guide portion 133 and a sliding portion 131, one of which is provided with a protrusion 1331, and the other is provided with a sliding groove matched with the protrusion 1331; there are several embodiments for the protrusion 1331 and the sliding groove; in the first embodiment, the extension direction of the protrusion 1331 is the moving direction of the smoke baffle 12; in the second embodiment, the extension direction of the sliding groove is the moving direction of the smoke baffle 12; in the third embodiment, the extension direction of the protrusion 1331 and the sliding groove is the moving direction of the smoke baffle 12. In this embodiment, the extension direction of the protrusion 1331 and the sliding groove is the moving direction of the smoke baffle 12, and the sliding connection between the smoke baffle 12 and the air inlet surface 111 is realized through the cooperation of the protrusion 1331 and the sliding portion 131, so that the second guide portion 133 can provide guidance for the movement of the sliding portion 131, so that the sliding portion 131 can move according to a certain preset path, thereby improving the stability and reliability of the movement of the smoke baffle 12.

[0066] In addition, it should be noted that, by the first guide portion 132 and the second guide portion 133 both cooperating with the sliding portion 131, the stability and reliability of the movement of the sliding portion 131 are improved, thereby facilitating the stability and reliability of the movement of the smoke shield 12. Furthermore, the first guide portion 132 and the second guide portion 133 are respectively connected to the opposite sides of the sliding portion 131, facilitating the connection between the first guide portion 132 and the second guide portion 133 and the sliding portion 131. In addition, the above form further improves the stability and reliability of the movement of the sliding portion 131, thereby facilitating the further improvement of the stability and reliability of the movement of the smoke shield 12.

[0067] It should be specifically explained that, in the present embodiment, the upper surface of the sliding part 131 is a rack. The rack is driven by a motor, and the meshing of the gear and the rack enables the sliding part 131 to drive the smoke baffle 12 to move, and the size of the air inlet 112 is adjusted by controlling the number of turns of the gear, which is approximately stepless adjustment, so that the range hood 1 can adapt to different cooking scenes. The second guide part 133 includes a main body and a protrusion 1331 protruding upward from the main body, and the end of the main body away from the protrusion 1331 is connected to the air inlet surface 111. A slide groove is provided on the lower surface of the sliding part 131, so that the sliding part 131 can be guided by the cooperation of the protrusion 1331 and the slide groove.

[0068] like Figure 1 , Figure 3 and Figure 4As shown, in addition, the air inlet 112 has a length a1 and a width d1, and the smoke baffle 12 has a length a2 and a width d2, a2>a1, d2>d1, so that the smoke baffle 12 can completely block the air inlet 112. The height of the flanging of the air inlet 112 is h, the height of the sliding groove close to the air inlet 112 is h1, the lowest height is h2, and the height of the rack slot is h3. 0.5h>h2+h3>h1, h1>h.

[0069] Along the moving direction of the smoke baffle 12 , guide members 13 are provided on both sides of the smoke baffle 12 , thereby improving the stability and reliability of the movement of the smoke baffle 12 .

[0070] In this embodiment, the sliding direction of the smoke baffle plate 12 is the width direction of the smoke collecting hood 11. In other embodiments, the sliding direction of the smoke baffle plate 12 may also be the length direction of the smoke collecting hood 11.

[0071] There are multiple air inlets 112, and the smoke shields 12 are arranged one-to-one with the air inlets 112. With the above-mentioned structural form, the smoke shields 12 are arranged one-to-one with the air inlets 112, so that the corresponding smoke shields 12 can be adjusted according to the different amounts of oil smoke at the multiple air inlets 112, so that the suction force can be mainly concentrated in the heavy oil smoke area, avoiding the problem of oil smoke escaping, and improving the oil smoke capture ability of the range hood 1.

[0072] It should be specifically explained that the range hood 1 may also include a control unit and an oil fume detection unit, and the oil fume detection unit is provided in a one-to-one correspondence with each air inlet 112. When the oil fume detection unit detects that there is oil fume at the air inlet 112, the control unit can drive the sliding part 131 to move and open the air inlet 112. When the amount of oil fume at each air inlet 112 is different, the amount of oil fume at each air inlet 112 detected by the oil fume detection unit can be compared, and the air inlet 112 with the largest amount of oil fume can be adjusted so that the opening size of this air inlet 112 is larger than the opening sizes of the other air inlets 112, so that the suction force can be mainly concentrated in the heavy oil fume area, avoiding the problem of oil fume escaping, and improving the oil fume capture ability of the range hood 1.

[0073] In addition, the smoke baffle 12, the sliding portion 131, the first guide portion 132 and the second guide portion 133 are disposed in the smoke collecting hood 11, so that the above structure can be protected by the smoke collecting hood 11, thereby increasing the service life of the above structure.

[0074] like Figure 1As shown, the air inlet 112 includes a main air inlet 1121 and an auxiliary air inlet 1122. The suction force of the main air inlet 1121 is greater than that of the auxiliary air inlet 1122. The auxiliary air inlet 1122 is arranged on both sides of the main air inlet 1121. An inwardly recessed cavity 113 is provided on the air inlet surface 111. The main air inlet 1121 and the auxiliary air inlet 1122 are both arranged in the cavity 113. Specifically, the suction force of the main air inlet 1121 is greater than that of the auxiliary air inlet 1122, so that the main air inlet 1121 has a greater pulling capacity for oil smoke than the auxiliary air inlet 1122, and thus the main air inlet 1121 has a greater ability to capture oil smoke than the auxiliary air inlet 1122. With the above-mentioned structure, when the oil smoke generated by cooking reaches the concave cavity 113, since the suction force of the main air inlet 1121 is greater than the suction force of the auxiliary air inlet 1122, the oil smoke is firstly adsorbed to the inside of the smoke collecting hood 11 through the main air inlet 1121. When the amount of oil smoke is large, the oil smoke in the concave cavity 113 cannot be immediately and completely captured from the main air inlet 1121, so that the excess oil smoke will diffuse to the surroundings, and the diffused and escaped oil smoke will be captured by the auxiliary air inlet 1122, thereby ensuring that the oil smoke cannot break through the auxiliary air inlet 1122 to escape, thereby improving the oil smoke capture capacity of the range hood 1, so that the main air inlet 1121 and the auxiliary air inlet 1122 can surround the oil smoke to prevent the oil smoke from escaping, thereby improving the user experience of the operator. In addition, when the amount of oil smoke is large, the oil smoke is first captured by the main air inlet 1121, and the oil smoke not captured by the main air inlet 1121 spreads to the surroundings along the top wall of the concave cavity 113, so that the escaped oil smoke is captured by the auxiliary air inlet 1122. In other words, the range hood 1 of the present application can improve the oil smoke capture capability of the range hood 1 through graded adsorption.

[0075] This embodiment further provides a kitchen system, which includes a range hood 1. With the above-mentioned structural form, the smoke baffle 12 can adjust the size of the air inlet 112 according to the amount of oil smoke, so that the suction force of the air inlet 112 can be adjusted according to the amount of oil smoke, so that the suction force of the air inlet 112 can be matched with the amount of oil smoke, thereby improving the user experience of the operator. With the above-mentioned structural form, the stability and reliability of the movement of the smoke baffle 12 are improved. In addition, the smoke baffle 12 can be limited by the first limiter 14 to prevent the smoke baffle 12 from moving beyond the range of the guide member 13.

[0076] In actual use, the kitchen system is a range hood 1 and a stove commonly used in daily kitchens, and the range hood 1 and the stove usually exist in pairs.
