When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0033] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0034] See also Figures 1 to 9The utility model discloses a range hood with a hidden oil cup. The range hood with a hidden oil cup disclosed by the utility model comprises a range hood body 1, an oil cup assembly 2 and a driving assembly 3. The range hood body 1 has a back plate 11 and an oil collecting chamber a located at the rear side of the back plate 11; the oil cup assembly 2 comprises a lifting frame 21 and an oil cup 22, and the oil cup 22 is detachably connected to the lifting frame 21; the driving assembly 3 is arranged in the oil collecting chamber, and the driving end of the driving assembly 3 is connected to the lifting frame 21, and is used to drive the lifting frame 21 to slide in the oil collecting chamber a, so that the oil cup 22 extends out from under the back plate 11 or retracts behind the back plate 11. After the oil cup 22 is connected to the bottom of the range hood body 1, the oil cup cannot be seen from the front side of the range hood body 1, and the gap at the connection between the oil cup and the range hood body cannot be seen, which will not affect the appearance of the range hood. When the oil cup needs to be cleaned, the drive component 3 is started, and the drive component 3 moves the lifting frame 21 downward from the oil collecting chamber a, and the oil cup 22 descends with the lifting frame 21 and is exposed from under the back plate 11. When the oil cup 22 is completely exposed from under the back plate 11, the user can easily remove the oil cup 22 from the lifting frame 21; and after the oil cup 22 is cleaned, since the height to which the lifting frame 21 is lowered is relatively low, it is convenient to connect the oil cup 22 to the lifting frame 21, making the installation of the oil cup 22 more convenient. After the oil cup 22 is connected to the lifting frame 21, the drive component 3 is started again, and drives the lifting frame 21 to move into the oil collecting chamber a, and the oil cup 22 rises with the lifting frame 21 and is hidden behind the back plate 11 again.

[0035] See also Figures 6 to 8 In the utility model of the range hood with hidden oil cup, the lifting frame 21 is provided with an oil cup hanging ear 211, and the oil cup 22 is provided with an oil cup hanging ear 221 corresponding to the oil cup hanging ear 211, and the oil cup hanging ear 221 is clamped with the oil cup hanging ear 211. When the oil cup 22 is connected to the lifting frame 21, the oil cup hanging ear 221 is clamped with the oil cup hanging ear 211, and the oil cup 22 is connected to the lower part of the lifting frame 21. When the oil cup 22 needs to be removed from the lifting frame 21, the oil cup 22 is pulled toward the user side, and the oil cup hanging ear 221 is separated from the oil cup hanging ear 211, and the oil cup 22 can be removed from the lifting frame 21. The clamping structure can not only make the oil cup 22 and the lifting frame 21 detachable, but also ensure the firmness of the connection between the oil cup hanging ear 211 and the oil cup hanging ear 221, so as to prevent the oil cup 22 from falling due to the loosening of the connection between the oil cup 22 and the lifting frame 21.

[0036] Since the oil cup 22 is connected to the lifting frame 21 through the oil cup hanger 221 and the oil cup hanging ear 211, if the oil cup hanger 221 and the oil cup hanging ear 211 are not properly connected, the oil cup 22 may be tilted, or the downward projection of the front side wall of the oil cup is located in front of the projection of the lower line of the back plate 11. In this way, when the driving component 3 drives the lifting frame 21 to rise and the oil cup 22 rises with the lifting frame 21, the oil cup 22 will interfere with the back plate 11 and collide with the back plate 11. If the driving component 3 does not stop, not only will the back plate 11 be damaged, but the oil cup 22 will also be deformed. Please refer to Figures 4 to 8 In view of this, in the utility model of the range hood with a hidden oil cup, the oil cup assembly 2 also includes a position detection member 23, which is used to detect whether the oil cup hanger 221 is connected to the oil cup hanging ear 211. After the oil cup hanger 221 is connected to the oil cup hanging ear 211, the position detection member 23 sends a signal to the control system of the range hood, and the control system of the range hood starts the driving assembly 3, and the driving assembly 3 starts and drives the lifting frame 21 to rise, and the lifting frame 21 drives the oil cup 22 to rise, and the oil cup 22 is hidden behind the back plate 11; when the oil cup hanger 221 is not connected to the oil cup hanging ear 211, the position detection member 23 sends a signal to the control system of the range hood, and the control system of the range hood sends a warning signal to remind the user that the oil cup 22 is not installed in place, and the user reinstalls the oil cup 22 until the oil cup hanger 221 is connected to the oil cup hanging ear 211. Setting the position detection member 23 can protect the oil cup 22 and the back plate 11.

[0037] See also Figures 4 to 8 In the range hood with a hidden oil cup of the present utility model, the in-place detection member 23 is arranged on the left and right sides of the lifting frame 21, and the oil cup hanger 221 is provided with a starter 222. After the oil cup hanger 221 is connected to the oil cup hanging ear 211, the starter 222 contacts the in-place detection member 23 and starts the in-place detection member 23. When the oil cup 22 is installed on the lifting frame 21, the oil cup hanger 221 is connected to the oil cup hanging ear 211. When the oil cup hanger 221 is connected to the oil cup hanging ear 211, the starter 222 on the oil cup hanger 221 contacts the in-place detection member 23 and starts the in-place detection member 23. The in-place detection member 23 sends a signal to the control system of the range hood, and the control system of the range hood starts the driving component 3 according to the signal. At this time, when the driving component 3 drives the oil cup 22 to move upward, the oil cup 22 will not interfere with the back plate 11. In addition, an in-place detection member 23 is simultaneously provided on both sides of the lifting frame 21 to prevent the oil cup hanger 221 on one side of the oil cup 22 from being connected to the oil cup hanging ear 211 while the oil cup hanger 221 on the other side is not connected to the oil cup hanging ear 211. In this way, the oil cup 22 is tilted relative to the lifting frame and will still interfere with the back plate 11.

[0038] See also Figures 6 to 8In the range hood with a hidden oil cup of the utility model, the in-place detection member 23 is a micro switch, the spring piece of the micro switch is arranged on the lower surface of the micro switch and the height of the lowest end is lower than the height of the starting member 222. After the oil cup hanger 221 is connected to the oil cup hanging ear 211, the starting member 222 presses the spring piece of the micro switch upward and starts the micro switch. When the oil cup 22 is installed on the lifting frame 21, the starting member 222 on the oil cup moves toward the micro switch with the oil cup 22. In the process of the oil cup hanger 221 on the oil cup 22 being connected to the oil cup hanger 211 on the lifting frame 21 and moving relative to the oil cup hanger 211, the starting member 222 gradually approaches the micro switch. When the oil cup hanger 221 is connected to the oil cup hanger 211 in place, the starting member 222 pushes the spring of the micro switch upward into place, and the micro switch is activated. The micro switch sends a signal to the control system of the range hood, and the control system of the range hood starts the drive component 3. The drive component 3 starts and drives the oil cup 22 to rise.

[0039] See also Figures 6 to 8 In the range hood with a hidden oil cup of the utility model, the spring piece of the micro switch is tilted downward, and its height is lowest on the side facing the oil cup hanging ear 211. The starting member 222 has a horizontally set starting surface, and the height of the starting surface is higher than the height of the lowest end of the spring piece of the micro switch. After the oil cup hanging ear 221 is connected to the oil cup hanging ear 211, the starting member 222 abuts against the lowest end of the spring piece of the micro switch. During the movement of the oil cup hanger 221 toward the oil cup hanger 211, the starting surface of the starting member 222 is closer and closer to the spring of the micro switch. When the oil cup 22 moves backward with respect to the lifting frame 21, due to the downward tilt of the spring, the lowest end of the spring begins to contact the starting surface. As the starting member 222 continues to move backward with the oil cup 22, the starting surface moves backward with the oil cup 22 and pushes the spring upward. When the oil cup hanger 221 is connected to the oil cup hanger 211, the starting member 222 pushes the spring of the micro switch upward into place, the micro switch is activated, and the micro switch sends a signal to the control system of the range hood. The control system of the range hood starts the drive component 3, and the drive component 3 starts and drives the oil cup 22 to rise.

[0040] See also Figures 3 to 5 In the utility model of the range hood with hidden oil cup, the width of the lifting frame 21 is smaller than the width of the oil cup 22. The oil cup 22 is arranged at the lower end of the oil collecting chamber a, and the downward projection of the lower surface of the oil collecting chamber a needs to fall into the opening of the oil cup 22 completely, so that no oil will fall to the outside of the oil cup 22. The lifting frame 21 needs to move in the oil collecting chamber a with the driving member 21, so the width of the lifting frame 21 is set smaller than the width of the oil cup 22, which does not affect the movement of the lifting frame 21 in the oil collecting chamber a, and can make the downward projection of the lower surface of the oil collecting chamber a fall into the opening of the oil cup 22 completely.

[0041] See also Figures 6 to 8 The utility model of the range hood with hidden oil cup has oil cup hanging ears 211 on the left and right sides of the bottom of the lifting frame 21, and the outer edges of the oil cup hanging ears 211 are flush with the corresponding sides of the lifting frame 21; two oil cup hangers 221 corresponding to the oil cup hanging ears 211 are arranged in the oil cup 22, and each oil cup hanger 221 includes a connecting part connected to the inner wall surface of the oil cup 22 and a hanging part hanging on the oil cup hanging ear 211, and the starter 222 is formed by stamping and folding the connecting part to form a flange, and the formed flange is located on the outer side of the connecting part. When the oil cup hanger 221 is connected to the oil cup hanging ear 211, the hanging part of the oil cup hanger 221 begins to move relative to the oil cup hanging ear 211. After the oil cup hanger 221 is connected to the oil cup hanging ear 211, the starter 222 is located directly below the micro switch and pushes the spring of the micro switch upward to the position, and the micro switch is started.

[0042] See also Figure 2 , Figure 4 , Figure 5 and Fig. 9 The utility model has a range hood with a hidden oil cup, and the range hood body 1 also includes a back plate frame 12, the back plate frame 12 has an oil collecting chamber a, the back plate 11 is connected to the front side of the back plate frame 12, and the bottom of the back plate frame 12 has a receiving groove b for accommodating the oil cup 22.
