[0002] Range hood is a commonly used kitchen appliance. Range hood works by using fluid dynamics principle, and negative pressure suction is generated by centrifugal fan installed in the range hood, so that the oil fume below the range hood is sucked into the centrifugal fan, and then is guided to be discharged outdoor after acceleration of the fan, so as to purify the kitchen environment. In the process of discharging the oil fume flow, most of the oil is separated out, so an oil collecting cup is usually installed at the bottom of the smoke collecting cover of the range hood to collect the separated oil.

[0003] At present, there are several ways to check the oil amount in the oil cup of the range hood, but each has its own shortcomings: one is to directly disassemble the oil cup to check, which is very inconvenient. The second is to set a transparent plastic area in the middle of the oil cup for users to check, but the display effect is not obvious, and users need to tilt their heads and necks to check, and the transparent plastic in the middle is easy to turn yellow and dark after long-term contact with oil stains, affecting the user's judgment. The third is to add a sensor on the oil cup to detect whether the oil amount reaches the warning line, but the addition of the sensor increases the production cost, on the other hand, the sensor is contaminated by the oil fume, which not only easily causes recognition error, but also may be damaged for a long time, such as the oil cup structure and the range hood applying the same disclosed in application No. 202222494762.4.

After the insertion piece 151 of the oil cup main body 15 is inserted into the insertion slot 200, the limiting protrusion 201 abuts against the bottom wall of the insertion piece, so as to ensure the stability of the insertion and installation of the insertion piece of the oil cup, and avoid the problem of shaking or easy detachment from the insertion slot 200.

[0042] The bottom wall of the casing 10 is further provided with a moving mechanism for moving the hangers 20 relative to the casing 10 along the left-right direction. The oil cup body 15 is installed on the hangers 20 and changes the position with the hangers 20 at least in a first state and a second state: in the first state, the left or right side of the top open of the oil cup body 15 moves out of the vertical projection of the casing 10 so that the oil in the oil cup body 15 is visible externally, in combination with Figure 1 and Figure 6 It is shown that the oil cup body 15 of the embodiment is moved to the right to expose from the right side of the casing 10. In the second state, the whole of the oil cup body 15 is located below the casing 10, and the top opening of the oil cup body 15 is blocked by the casing 10 and is not visible externally. Similarly, the oil cup body 15 of the embodiment is moved from the right to the left to switch from the first state to the second state. In the second state, the oil cup body 15 is hidden in the bottom of the casing 10, which ensures the overall aesthetics of the range hood.

[0043] The moving mechanism includes a driving motor 31, a first swing arm 321, a second swing arm 322 and a linkage rod 34.

[0044] The driving motor 31 is arranged in the casing 10, and the output shaft thereof extends vertically and is connected with a first shaft 331 arranged vertically, so as to drive the first shaft 331 to rotate about the axis thereof. Specifically, the first shaft 331 extends through the bottom wall of the casing 10 from bottom to top and extends into the casing 10 to be connected with the output shaft of the driving motor 31, and the lower end of the first shaft 331 is connected with the first end of the first swing arm 321, so as to drive the first swing arm 321 to rotate about the first shaft 331. The driving motor 31 is arranged in the casing 10, so that the oil cup body 15 can be as close to the bottom of the casing 10 as possible, which ensures the overall aesthetics of the range hood. The first swing arm 321 and the second swing arm 322 are both arranged horizontally. The first end of the first swing arm 321 is connected with the first shaft 331, and the second end is rotatably connected with the left hanger 20. The first end of the second swing arm 322 is rotatably connected to the casing 10 through a second shaft 332 extending vertically, and the second end is rotatably connected with the right hanger 20.

The whole oil cup body 15 is also slightly backward, hidden in the bottom of the casing 10. As shown in Figure 7 As shown, when the oil cup body 15 is in the second state, the first swing arm 321 and the second swing arm 322 are both extended forward and backward, and the second end of the first swing arm 321 is located on the front side of the first end, and the second end of the second swing arm 322 is located on the front side of the first end. The design of the above-mentioned movement mechanism makes the hanging rack 20 and the oil cup not only moveable in the left-right direction, but also moveable in the front-back direction. When the oil cup body 15 is in the first state, the position of the oil cup body 15 can also be moved forward by a certain distance, which facilitates the user to contact the oil cup and remove it.

[0045] In order to avoid the oil cup from falling off due to being too heavy, a support bracket 121 can be provided on the left side or the right side of the bottom of the casing 10. The support bracket 121 has a receiving groove for receiving one end of the oil cup body 15. Figure 6 As shown, the support bracket 121 of the present embodiment is one, which is provided on the left side of the bottom of the casing 10, i.e. on the side where the driving motor 31 of the movement mechanism is located. The front side and the right side of the support bracket 121 are both provided with openings to facilitate the left end of the oil cup body 15 to move rightward and forward, avoiding interference problems.

[0046] When it is necessary to check the oil amount in the oil cup, the movement mechanism can drive the oil cup body 15 to offset relative to the casing 10 by a certain distance to the side, so that the oil amount in the oil cup body 15 can be clearly and intuitively observed, and the disassembly and installation of the oil cup are also facilitated. At the same time, when it is not necessary to check the oil amount in the oil cup or disassemble and install the oil cup, the oil cup body 15 is hidden in the bottom of the casing 10, which ensures the overall aesthetics of the range hood.
