For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] like Figure 1 As shown, the smoke inlet device provided by the utility model comprises: a smoke collecting hood 100 and a flow distribution mechanism. The smoke collecting hood 100 comprises an upper hood body 110 and a lower hood body 120, which are in a "7" shape as a whole.

[0046] like Figure 6 As shown, the smoke collecting hood 100 is provided with a top smoke inlet 111, a side smoke inlet 121, a first smoke outlet 210, and a second smoke outlet 220. The smoke collecting hood 100 has a first flow channel 310 connecting the top smoke inlet 111 and the first smoke outlet 210, and a second flow channel 320 connecting the side smoke inlet 121 and the second smoke outlet 220. The first flow channel 310 and the second flow channel 320 are relatively independent, and the oil smoke inside the first flow channel 310 and the second flow channel 320 will not flow to each other.

[0047] like Figure 6 As shown, the first smoke outlet 210 and the second smoke outlet 220 are both connected to the fan assembly 400, that is, the total negative pressure generated by the fan assembly 400 will be applied to the first smoke outlet 210 and the second smoke outlet 220 at the same time. The fan assembly 400 has a fan inside, and the inlet of the fan assembly 400 is located at the lower end surface, and the outlet is located at the upper end surface.

[0048] The flow distribution mechanism is connected to the smoke hood 100, and is used to adjust the opening of the first smoke outlet 210 and the second smoke outlet 220 respectively, so that the negative pressure ratio distributed by the fan assembly 400 to the first smoke outlet 210 and the second smoke outlet 220 is adjustable. The change of the opening of the first smoke outlet 210 and the second smoke outlet 220 can be achieved by blocking the baffle or opening and closing the smoke inlet. When the total negative pressure value generated by the fan assembly 400 is a fixed value, the negative pressure distributed to the first smoke outlet 210 and the second smoke outlet 220 will be inversely proportional, that is, the larger the opening of the first smoke outlet 210, the more negative pressure is distributed, and the less negative pressure is distributed to the second smoke outlet 220, and vice versa.

[0049] When cooking, the user can adjust the opening of the first smoke outlet 210 and the second smoke outlet 220 according to different cooking conditions. The larger the opening, the greater the negative pressure distributed by the fan assembly 400, thereby changing the smoking effect of the corresponding smoke inlet. For example, when the oil smoke is mostly concentrated at a higher position, the opening of the first smoke outlet 210 can be increased and the opening of the second smoke outlet 220 can be reduced; conversely, when the oil smoke is concentrated at a lower position, the opening of the second smoke outlet 220 can be increased and the opening of the first smoke outlet 210 can be reduced. Since the first flow channel 310 and the second flow channel 320 are relatively independent, the two will not affect each other, avoiding the occurrence of partial pressure, and the negative pressure can be concentrated to the required smoke inlet, so it can adapt to different cooking conditions.

[0050] like Figure 6 As shown, in this embodiment, the flow distribution mechanism includes a movable baffle 510, which is disposed between the first smoke outlet 210 and the second smoke outlet 220. The movable baffle 510 can rotate or slide in the front-to-back direction relative to the smoke collecting hood 100, and is used to adjust the openings of the first smoke outlet 210 and the second smoke outlet 220, respectively, so that the openings of the first smoke outlet 210 and the second smoke outlet 220 are inversely proportional. When the movable baffle 510 moves toward the front side, the opening of the first smoke outlet 210 decreases, and the opening of the second smoke outlet 220 increases. Conversely, when the movable baffle 510 moves toward the rear side, the opening of the first smoke outlet 210 increases, and the opening of the second smoke outlet 220 decreases.

[0051] Specifically, Figure 6 As shown, a smoke inlet channel is provided inside the smoke hood 100. A total smoke outlet is provided on the smoke hood 100, and the total smoke outlet is provided on the top surface of the upper cover body 110 of the smoke hood 100. The inlet of the fan assembly 400 is tightly connected with the total smoke outlet of the smoke hood 100. The movable baffle 510 is located in the smoke inlet channel, and the movable baffle 510 divides the smoke inlet channel into a first channel 310 and a second channel 320, and the movable baffle 510 divides the total smoke outlet into a first smoke outlet 210 and a second smoke outlet 220. The lower edge of the movable baffle 510 can be movably connected to the bottom surface of the upper cover body 110, and after the movable baffle 510 moves forward and backward, the opening of the first smoke outlet 210 and the second smoke outlet 220 can be changed.

[0052] like Figure 7 As shown, in this embodiment, the movable baffle 510 is rotatably connected to the upper cover body 110, and the movable baffle 510 can be rotatably connected to the corner of the bottom plate of the upper cover body 110 and the front plate of the lower cover body 120. The movable baffle 510 can swing back and forth at the main smoke outlet to separate the main smoke outlet. In other feasible solutions, a sliding connection method can also be adopted, and the movable baffle 510 moves in a straight line in the front and rear directions.

[0053] In this embodiment, Figure 7 As shown, the smoke hood 100 is provided with side panels 520 located on the left and right sides of the movable baffle 510, respectively. The side panels 520 are located in the upper cover body 110, and the lower edge of the side panels 520 is connected to the inner surface of the bottom plate of the upper cover body 110. The front edge of the side panels 520 is connected to the inner surface of the front plate of the upper cover body 110. The upper edge of the side panels 520 can directly extend upward and connect to the inlet of the fan assembly 400, and the rear edge of the side panels 520 extends backward all the way into the lower cover body 120. The movable baffle 510 is located between the gaps between the two side panels 520. The movable baffle 510 should be able to cover the gap between the left and right side panels 520, and should always be adjacent to the side panels 520 without gaps during its movement. The movable baffle 510 separates the front and rear spaces and forms the first flow channel 310 and the second flow channel 320. The left and right edges of the movable baffle 510 are in contact with the left and right side plates 520 respectively, so as to prevent the first flow channel 310 and the second flow channel 320 from being connected from the left and right sides of the movable baffle 510 .

[0054] Furthermore, the setting of the movable baffle 510 is not limited to the corners of the upper cover body 110 and the lower cover body 120. It only needs to meet the requirement that one side of the movable baffle 510 is tightly connected to the upper cover body 110 and is adjacent to the side panel 520 without a gap, forming a closed space on the remaining five sides except the top and the main smoke outlet.

[0055] like Figure 7 As shown, the flow distribution mechanism further includes a driving module 600 connected to the movable baffle 510, and the driving module 600 may include, but is not limited to, a connecting rod assembly and a push rod motor, as long as it can drive the baffle to rotate relative to the smoke hood 100. In this embodiment, the left and right sides of the lower end of the movable baffle 510 have rotating shafts, and the rotating shafts pass through the side plates 520 on both sides thereof, and the side plates 520 are fixed relative to the upper cover body 110, so that the movable baffle 510 can rotate relative to the smoke hood 100.

[0056] In this embodiment, the driving module 600 is located in a gap between the side plate 520 on the right side of the movable baffle 510 and the right side wall of the smoke collecting hood 100 .

[0057] In other feasible solutions, the flow distribution mechanism includes a first flow valve and a second flow valve, wherein the first flow valve is disposed at the first smoke outlet 210 and is used to adjust the opening of the first smoke outlet 210; the second flow valve is disposed at the second smoke outlet 220 and is used to adjust the opening of the second smoke outlet 220. In this solution, the openings of the first smoke outlet 210 and the second smoke outlet 220 can be independently controlled to separately adjust the openings of the first smoke outlet 210 and the second smoke outlet 220, thereby cooperating to complete the distribution of the combined force of the negative pressure.

[0058] like Figure 6As shown, a first smoke sensor 710 is disposed in the first flow channel 310, and a second smoke sensor 720 is disposed in the second flow channel 320. The first smoke sensor 710 and the second smoke sensor 720 are respectively connected to the flow distribution mechanism through a controller.

[0059] The first smoke sensor 710 can be arranged in the upper housing 110 and at a distance from the front side of the top smoke inlet 111. The second smoke sensor 720 can be arranged in the lower housing 120 and at a distance from the upper side of the side smoke inlet 121. The two smoke probes are used to realize the automation of air volume adjustment, eliminating the need for users to adjust the air volume by themselves. For example, if the smoke concentration detected by the first smoke sensor 710 is greater than the smoke concentration detected by the second smoke sensor 720, the first smoke outlet 210 can be adjusted to be larger.

[0060] The smoke inlet device has a first state, a second state and a third state. Figure 4 and Figure 5 As shown, in the first state, the second smoke outlet 220 is completely closed, and the first smoke outlet 210 is completely open, and smoke is completely fed in through the top smoke inlet 111. When the movable baffle 510 rotates to the rearmost side and contacts the rear plate of the upper cover 110, it is the first state, the second smoke outlet 220 is completely blocked, and no negative pressure can be generated. The oil smoke cannot be drawn away through the side smoke inlet 121, and can only enter the range hood from the top smoke inlet 111, thereby realizing a separate top air intake.

[0061] like Figure 2 and Figure 3 As shown, in the second state, the first smoke outlet 210 is completely closed, and the second smoke outlet 220 is completely open, and smoke is completely fed in through the side smoke inlet 121. When the movable baffle 510 rotates to the frontmost side and contacts the front edge of the main smoke outlet, it is the second state, in which the first smoke outlet 210 is completely blocked, the top smoke inlet 111 cannot generate negative pressure, and the oil smoke cannot be drawn out through the top smoke inlet 111, and can only enter the range hood from the side smoke inlet 121, thereby realizing a separate lower air intake.

[0062] like Figure 6As shown, in the third state, the first smoke outlet 210 and the second smoke outlet 220 are partially opened, and the top smoke inlet 111 and the side smoke inlet 121 are simultaneously inletting smoke. When the movable baffle 510 is between the above two states, it is the third state at this time, and the total smoke outlet is divided into two parts with areas A and B respectively, then the total negative pressure generated by the fan assembly 400 is distributed to the top smoke inlet 111 and the side smoke inlet 121 according to the area ratio (A: B), when the movable baffle 510 is in different positions after the rotation movement, the divided areas A and B are also different in size, thereby realizing the allocation of the air intake of the top smoke inlet 111 and the side smoke inlet 121 to adapt to the different air intake conditions required for different working conditions. The user can control the switch panel to make the push rod motor extend and retract to drive the rotation of the movable baffle 510, thereby realizing the switching use of the above three states.

[0063] The range hood provided by the utility model comprises the above-mentioned smoke inlet device. Since the range hood provided by the utility model adopts the above-mentioned smoke inlet device, the range hood provided by the utility model also has the advantages of the smoke inlet device.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
