[0031] Please refer to Figure 1 , Figure 2 and Figure 3 , the present application first provides a range hood, comprising a shell 100, a receiving cavity is formed in the shell 100, a partition plate 10 is fixedly arranged in the shell 100 to divide the receiving cavity into two fan cavities 20, one fan 21 is arranged in each of the two fan cavities 20, and the air outlet pipes of the two fans 21 are communicated with each other and extend to the outside of the shell 100; each of the two fan cavities 20 has an air inlet 22 communicated with the outside, and an air inlet baffle 30 is movably arranged on the shell 100, the air inlet baffle 30 can open or close the first air inlet 22a of the first fan cavity 20a; the partition plate 10 is provided with a through hole 11 communicated with the two fan cavities 20, and a ventilation baffle 40 is movably arranged on the shell 100, the ventilation baffle 40 can open or close the through hole 11.

[0032] For the convenience of description, in the present application, the two fan cavities 20 are respectively a first fan cavity 20a and a second fan cavity 20b, the first fan cavity 20a is provided with a first fan 21a inside, and the first fan cavity 20a has a first air inlet 22a, the second fan cavity 20b is provided with a second fan 21b inside, and the second fan cavity 20b has a second air inlet 22b.

[0033] In the present application, by arranging two fan cavities 20 and two fans 21 inside, on the one hand, each air inlet 22 can face one cooking bench for air suction, the air speed is more uniform and the smoke suction effect is more stable, on the other hand, the two fans 21 of the double-fan structure are smaller than the single-fan structure and produce less noise, which can effectively improve the user experience.

[0034] It is worth mentioning that since the fans 21 of the double-fan structure are smaller than the single-fan, the independent smoke exhaust effect of each fan 21 will also be weakened compared with the single-fan structure, for this reason,

[0035] In the present application, the ventilation baffle 40 capable of opening or closing the through hole 11 and the air inlet baffle 30 capable of opening or closing the first air inlet 22a are arranged, so that the user can adjust the oil fume suction mode according to the actual use demand to meet the two demands of double-cooking bench smoke suction or single-cooking bench large suction force smoke suction.

[0036] Specifically, in the double suction state, the air inlet baffle 30 is opened, the ventilation baffle 40 is closed, and the two fans 21 independently operate to suck the oil fume generated by the corresponding cooking table into the fan cavity 20 through the respective air inlet 22 and discharge it through the air outlet pipe to meet the oil fume suction demand of the double cooking table.

[0037] In the single suction state, the air inlet baffle 30 is closed, and the ventilation baffle 40 is opened. At this time, the range hood can only intake air through the second air inlet 22b, and the oil fume sucked into the inside of the shell 100 through the second air inlet 22b is divided into two paths. One path is sequentially discharged along the second fan cavity 20b, the second fan 21b and the air outlet pipe, and the other path is sequentially discharged along the second fan cavity 20b, the through hole 11, the first fan cavity 20a, the first fan 21a and the air outlet pipe. That is, through the cooperative work of the first fan 21a and the second fan 21b, a stronger negative pressure is formed in the second fan cavity 20b to suck oil fume, so as to solve the problem of weak wind force of a single fan and meet the demand of single-cooking-table large suction force.

[0038] As can be easily understood, whether in the single suction state or the double suction state, the air inlet 22 is directly opposite to the cooking table, and the smoke suction area is more concentrated and stable, thereby solving the problem of oil fume escaping from both sides due to uneven air speed of the smoke suction port during cooking.

[0039] Please refer to Figure 1 , Figure 2 and Figure 3 , in some embodiments, the linkage assembly 50 is arranged in the shell 100 to connect the air inlet baffle 30 and the ventilation baffle 40, so that when one of the air inlet baffle 30 and the ventilation baffle 40 moves, the other one is driven to move through the linkage assembly 50.

[0040] The range hood has a single suction state and a double suction state. In the single suction state, the air inlet baffle 30 is closed and the ventilation baffle 40 is opened. In the double suction state, the air inlet baffle 30 is opened and the ventilation baffle 40 is closed.

[0041] Please refer to Figure 1 , Figure 2 and Figure 3 , in some embodiments, the guide rail 12 is fixedly arranged on the partition plate 10, and the ventilation baffle 40 is slidably connected with the guide rail 12; the air inlet baffle 30 is hingedly connected with the shell 100.

[0042] The ventilation baffle 40 is slidably connected with the guide rail 12, so that the opening area of the through hole 11 can be infinitely adjusted with the movement of the ventilation baffle 40. Similarly, the air inlet baffle 30 is hingedly connected with the shell 100, so that the area of the first air inlet 22a can be infinitely adjusted with the rotation of the air inlet baffle 30.

[0043] Thus, the user can adjust the state of the air inlet baffle 30 and the ventilation baffle 40 according to the actual needs to meet the oil fume suction demand in more different scenarios, thereby improving the versatility of the oil fume suction assembly.

[0044] Specifically, with the opening of the ventilation baffle 40, the air inlet baffle 30 gradually closes, and the oil fume suction effect of the second air inlet 22b gradually increases, and the oil fume suction effect of the first air inlet 22a gradually decreases. Conversely, the same applies.

[0045] Of course, in other embodiments, the ventilation baffle 40 and the air inlet baffle 30 can also be connected to the shell 100 through other commonly used connecting structures, as long as they can be infinitely adjusted relative to the shell 100 and can open and close the corresponding openings. This application does not exemplify one by one.

[0046] Please refer to Figure 1 and Figure 4 In some embodiments, the linkage assembly 50 includes a first connecting rod 51, a second connecting rod 52, a third connecting rod 53, a fourth connecting rod 54, and a fifth connecting rod 55 connected in turn, wherein the second connecting rod 52 and the fourth connecting rod 54 are both rotationally connected to the inner wall of the shell 100, the two ends of the third connecting rod 53 are respectively hinged to the second connecting rod 52 and the fourth connecting rod 54, the two ends of the first connecting rod 51 are respectively hinged to the air inlet baffle 30 and the second connecting rod 52, and the two ends of the fifth connecting rod 55 are respectively hinged to the ventilation baffle 40 and the fourth connecting rod 54.

[0047] Taking the upward sliding of the ventilation baffle 40 as an example, the ventilation baffle 40 drives the fifth connecting rod 55 to drive the fourth connecting rod 54 to rotate counterclockwise, the fourth connecting rod 54 pulls the third connecting rod 53 to the right, thereby driving the second connecting rod 52 to rotate counterclockwise through the third connecting rod 53, and finally the second connecting rod 52 controls the opening and closing angle of the air inlet baffle 30 through the first connecting rod 51.

[0048] Of course, in other embodiments, the linkage assembly 50 can also use other commonly used transmission structures, as long as it can drive one to move cooperatively through the other of the ventilation baffle 40 or the air inlet baffle 30. This application does not exemplify one by one.

[0049] Please refer to Figure 2 and Figure 3In some embodiments, the two air inlets 22 are parallel to each other in the orientation direction, the air inlet baffle 30 is hinged to one end of the first air inlet 22a away from the second air inlet 22b, so that the opening formed between the air inlet baffle 30 and the first air inlet 22a is oriented towards the second air inlet 22b; during the switching of the range hood from the double suction state to the single suction state, due to the opening formed between the air inlet baffle 30 and the first air inlet 22a being oriented towards the second air inlet 22b, the oil fume corresponding to the cooking bench on the second air inlet 22b side can also be sucked in through the first air inlet 22a, thereby increasing the oil fume suction effect on the cooking bench on the second air inlet 22b side.

[0050] Please refer to Figure 1 , Figure 2 and Figure 3 , in some embodiments, the second fan 21b is located on the side close to the second air inlet 22b compared to the through hole 11, and the first fan 21a is located on the side close to the through hole 11; to reduce the air flow path distance between the two fans 21 and the second air inlet 22b in the single suction state, to improve the wind speed at the position of the second air inlet 22b, and to improve the oil fume suction effect in the single suction state.

[0051] Please refer to Figure 1 , Figure 2 and Figure 3 , in some embodiments, the air outlet pipe of the first fan 21a extends through the partition plate 10 and the second fan cavity 20b to the outside of the shell 100, and the air outlet pipe of the second fan 21b extends to the side away from the second air inlet 22b to communicate with the air outlet pipe of the first fan 21a.

[0052] Please refer to Figure 1 , Figure 2 and Figure 3 , in some embodiments, the shell 100 is further provided with a driving member 60, the output end of the driving member 60 is in power connection with one of the ventilation baffle 40 or the air inlet baffle 30, to drive the air inlet baffle 30 and the ventilation baffle 40 to move.

[0053] Specifically, the driving member 60 is a telescopic motor fixed to the partition plate 10, and the telescopic end is fixed to the ventilation baffle 40 to drive the air inlet baffle 30 to slide along the guide rail 12.

[0054] In some embodiments, the second air inlet 22b of the second fan cavity 20b is provided with a smoke concentration sensor (not shown in the figure), which is in electrical connection with the driving member 60.

[0055] The smoke concentration sensor can sense the smoke concentration at the position of the second air inlet 22b and control the driving member 60 to start, so as to adjust the oil fume suction effect at the position of the second air inlet 22b to an appropriate intensity by adjusting the moving state of the air inlet baffle 30 and the ventilation baffle 40.

[0056] Specifically, the first fan 21a and the second fan 21b are electrically connected with the smoke concentration sensor, and are divided into strong and weak two gears. When the range hood starts to work, the smoke concentration sensor detects the real-time smoke concentration C at the position of the second air inlet 22b. The smoke concentration sensor is pre-set with multiple smoke concentration gears T1, T2 and T3.

[0057] When C < T1 is detected, the range hood is adjusted to a double suction state, at which time both cooking tables can work, and the user can adjust the corresponding fan 21 gear according to the oil fume concentration generated by the two cooking tables;

[0058] When T1 < C < T3 is detected, the air inlet baffle 30 and the ventilation baffle 40 are adjusted between the single suction state and the double suction state. At this time, the corresponding cooking table of the first air inlet 22a can still work. In order to ensure the smoke suction effect, the smoke concentration sensor controls the first fan 21a to be in the strong gear;

[0059] When T1 < C < T3 is detected, the included angle between the air inlet baffle 30 and the first air inlet 22a is adjusted to 65°;

[0060] When T2 < C < T3 is detected, the included angle between the air inlet baffle 30 and the first air inlet 22a is adjusted to 45°;

[0061] When C > T3 is detected, the range hood is adjusted to a single suction state. At this time, the smoke concentration sensor controls the second fan 21b to be in the strong gear to ensure the smoke suction effect, and the user can further adjust the smoke suction effect of the second air inlet 22b through the gear of the first fan 21a;

[0062] Of course, in other embodiments, more smoke gears can also be pre-set, and different included angles can be corresponded. As long as the included angle gradually decreases with the increase of the smoke concentration, the present application does not exemplify one by one.

[0063] The second aspect of the present application provides a multifunctional cooking equipment, which comprises an equipment main body, two cooking tables and the above-mentioned range hood. The two cooking tables and the range hood are arranged on the equipment main body, and the two cooking tables correspond to the two air inlets 22 respectively.

[0064] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described. However, as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the present application.

[0065] The above embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are within the scope of protection of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
