The oil screen disclosed in the prior art has a plurality of air inlets. However, the air inlet area of the oil screen in the prior art is fixed and cannot be adjusted, so the air intake cannot be adjusted according to different cooking scenarios. If the air inlet area is large, the inlet air velocity decays quickly, the effective smoke suction area is small, and the overall capture ability of the rising oil fume is poor. In addition, the air inlet position is fixed, and the capture ability of the oil fume generated by the edge of the pot under harsh working conditions is weak, and the smoke may escape. Therefore, the prior art needs to be further improved. SUMMARY

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] like Figures 1 to 5 As shown, this embodiment discloses an oil filter assembly and a range hood using the oil filter assembly. Figure 1 As shown, the range hood in this embodiment includes a housing 7, a smoke inlet 71 is provided on the housing 7, and an oil filter assembly 8 is provided at the smoke inlet 71.

[0029] like Figures 2 to 5 As shown, the oil mesh assembly in this embodiment includes a filter plate 1, a baffle 2, and a drive mechanism 3. The filter plate 1 has air inlets 11 distributed on it. The baffle 2 is constrained on the filter plate 1 in a way that allows it to move relative to the filter plate 1. The baffle 2 changes the air inlet area and air inlet position as its position changes. The drive mechanism 3 is constrained on the filter plate 1 and is drivenly connected to the baffle 2 to drive the baffle 2 to move.

[0030] like Figure 2 As shown, the air inlets 11 are divided into x groups, each group of air inlets 11 is arranged side by side along the length of the filter plate 1, and each group of air inlets 11 includes N air inlets 11 arranged side by side at intervals along the width of the filter plate 1, where x is a positive integer and N is a positive integer greater than or equal to 2. There are x groups of baffles 2, all of which are located on the back of the filter plate 1; and each group of baffles 2 corresponds to one group of air inlets, each group of baffles 2 includes M baffles 2 arranged at intervals, where M is a positive integer greater than or equal to 1 and M < N. In this embodiment, x = 2.

[0031] Each set of baffles 2 has the following two states under the drive of the drive mechanism 3:

[0032] In the first state, each baffle 2 in each group of baffles 2 corresponds to closing one air inlet 11, and NM air inlets 11 in each group of air inlets are in the open state; for example Figure 2As shown, N=3, M=2, that is: each group of air inlets 11 in this embodiment has 3 air inlets, and each group of baffles 2 has 2 baffles;

[0033] In the second state, each baffle 2 in each group of baffles 2 is positioned between two adjacent air inlets 11, and all air inlets 11 in each group of air inlets 11 are in the open state; such as Figure 5 As shown, each air inlet 11 is in the open state;

[0034] M baffles 2 in each set of baffles 2 are connected by brackets 4, and the drive mechanism 3 is driven by the brackets 4. A guide rod 6 extending along the width direction is provided on the back of the filter plate 1, and the bracket 4 has an insertion hole 42 for the guide rod 6 to pass through; and in this embodiment, the drive mechanism 3 is a drive motor, the power output shaft of the drive motor is provided with a gear 51, and the bracket 4 is provided with a rack 41 that meshes with the gear 51, the rack 41 extending along the width direction of the filter plate 1. Figure 2 As shown, the bracket 4 in this embodiment is U-shaped, and the two ends of the U-shaped bracket are fixedly connected to two baffles 2 respectively.

[0035] The working process of the oil mesh assembly in this embodiment is as follows:

[0036] By driving a single set of baffles 2 to move by a drive motor, the air inlet is at least partially blocked, thereby changing the air intake area of ​​the air inlet and changing the flow ratio of the left and right sets of air inlets to achieve flow distribution.

[0037] When the oil fume concentration at both the left and right air inlets is low, by moving both the left and right baffles 2 to the upper part of each air inlet, the oil fume can be drawn in through the lower part of the air inlet, thus precisely controlling the smoke.

[0038] When the oil fume concentration at the left and right air inlets is high or the oil fume rises quickly, both sets of baffles 2 are moved to the lower half of each air inlet, and air is drawn in through the upper half of the air inlet to control the spread of oil fumes and the escape of oil fumes from the edge area.

[0039] When the oil fume concentration of one group of air inlets is relatively low, while the oil fume concentration of another group of air inlets is relatively high or the oil fume rises faster, the baffle 2 of the group with lower oil fume concentration is moved to the upper part of the air inlet, and the baffle 2 of the group with higher oil fume concentration is moved to the lower part of the air inlet, so as to control the oil fume diffusion in the corresponding area respectively.

[0040] When the left and right baffles 2 are respectively located in the upper or lower half of each air inlet, the air intake area is smaller than that of the baffle 2 in the center position, the air intake wind speed is increased, and the control effect of oil fume is improved by narrow air intake.

[0041] When the oil fume concentration at both the left and right air inlets is low, and there is no oil fume diffusion around the edge of the cookware, then move both sets of baffles 2 to the middle position of each air inlet (e.g., Figure 5 As shown in the image, the range hood can effectively control cooking fumes. Compared to narrow air inlets, the range hood has a larger air intake area and therefore operates with lower noise.

However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
