[0045] The present invention provides a range hood, such as Figure 1-3As shown, the range hood includes a range hood shell 1, an oil cup 2 and a limiting assembly 3. The range hood shell 1 includes an upper shell 11 and a lower shell 12. The upper shell 11 and the lower shell 12 are independent of each other and correspond to each other up and down. A smoke collecting chamber 110 is formed inside the upper shell 11, and an installation chamber 120 is formed inside the lower shell 12. An oil leakage channel that is interconnected is provided between the smoke collecting chamber 110 and the installation chamber 120; the oil cup 2 is inserted into the installation chamber 120 and is detachably connected to the lower shell 12, and its open end is located below the outlet end of the oil leakage channel to collect oil stains in the smoke collecting chamber 110; the limiting assembly 3 is provided on the front side of the lower shell 12 for limiting the installation position of the oil cup 2. The present application divides the range hood housing 1 into two parts, the upper housing 11 and the lower housing 12, which are independent of each other and form a smoke collecting chamber 110 and an installation chamber 120, respectively. In this way, all the oil and dirt are intercepted in the upper housing 11. The upper housing 11 is used to collect the oil and dirt, and the lower housing 12 is used to place the oil cup 2. The oil leakage channel is used to guide the oil and dirt in the smoke collecting chamber 110 into the oil cup 2. It should be noted that the present application uses the upper housing 11 and the lower housing 12 to form a combination to meet the requirements of the range hood shell appearance. In addition, the upper housing 11 and the lower housing 12 are not connected by any other gaps except the oil leakage channel, which reduces the risk of oil leakage from the range hood shell. In other words, while meeting the appearance requirements, the present application can collect all the oil and dirt into the oil cup 2. It has a simple structure, low cost, and a complete and novel oil circuit layout, which solves the problem that the bottom of the ultra-thin range hood shell is narrow and not suitable for setting the oil cup 2 and oil leakage.

[0046] In a preferred embodiment of the present invention, Figure 1-6 The upper shell 11 shown includes a bottom plate 111, and the lower shell 12 includes a top plate 121. The bottom plate 111 and the top plate 121 are arranged in a close-fitting manner. The bottom plate 111 is provided with a first oil leakage hole 1110, and the top plate 121 is provided with a second oil leakage hole 1210 corresponding to the first oil leakage hole 1110. The first oil leakage hole 1110 and the second oil leakage hole 1210 are connected to form an oil leakage channel, so that oil in the smoke collection chamber 110 can enter the oil cup 2 through the oil leakage channel. The bottom plate 111 and the top plate 121 have the same structure and correspond to each other from top to bottom. In addition, except for the first oil leakage hole 1110 and the second oil leakage hole 1210, the bottom plate 111 and the top plate 121 have no other holes, so as to facilitate the assembly of the upper shell 11 and the lower shell 12 and prevent oil leakage.

[0047] In a preferred embodiment of the present invention, Figure 1-6The front ends of the upper and lower shells 11, 12 are both open and connected to a glass panel 4. The glass panel 4 has openings 40 corresponding to the smoke collection chamber 110 and the mounting chamber 120. The openings 40 and the upper shell 11 form a smoke inlet 401 connected to the smoke collection chamber 110. The openings 40 and the lower shell 12 form a mounting port 402 connected to the mounting chamber 120. The oil cup 2 is inserted into the mounting chamber 120 through the mounting port 402. The size of the openings 40 is controlled according to design requirements to meet the requirements of smoke exhaust and oil cup 2 installation. The structure is simple, aesthetically pleasing, and easy to clean.

[0048] In a preferred embodiment of the present invention, Figure 3 、 4 The front end of the top plate 121 shown in FIG6 is provided with a bent portion 1211 extending inward and rearward. The front end of the bottom plate 111 is bent upward to form a first flange 1111. The inward and rearward extension of the bent portion 1211 enhances the structural strength and load-bearing capacity of the top plate 121 and also facilitates the installation and removal of the oil cup 2. The first flange 1111 also increases the structural strength of the bottom plate 111.

[0049] In a preferred embodiment of the present invention, Figure 3-6 The illustrated limiting assembly 3 includes a limiting plate 31, which is provided on the rear side of the glass panel 4, with both ends connected to the front end of the lower shell 12, and a top portion thereof extending upward to the first flange 1111 and bending inward and downward to form a second flange 311. A through hole 310 for inserting the oil cup 2 is provided in the middle of the limiting plate 31; wherein, the height of the front side wall of the oil cup 2 is greater than the height of the through hole 310, so that when the oil cup 2 is configured in the installation position, the inner side of the front side wall of the oil cup 2 abuts against the outer side of the limiting plate 31. The limiting plate 31 of the present application is provided with a through hole 310 for inserting the oil cup 2, and can also define the insertion position of the oil cup 2. When the oil cup 2 is inserted into the set installation position, the interior of the oil cup 2 is fully inserted into the lower shell 12 and is located below the second oil leakage hole 1210, for receiving oil and dirt discharged from the smoke collecting chamber 110. In addition, the second flange 311 can not only enhance the structural strength of the limiting plate 31, but also cooperate with the first flange 1111 to facilitate the installation of the limiting plate 31 and improve assembly efficiency.

[0050] In a preferred embodiment of the present invention, Figure 1-3 The range hood shown in the figure further includes a flap assembly 5 and a drive assembly 6. The flap assembly 5 is located in front of the through hole 310 and is hinged to the upper shell 11. The drive assembly 6 is connected between the flap assembly 5 and the upper shell 11 to drive the flap assembly 5 to open and close the through hole 310. When the flap assembly 5 is configured to be in the closed position, the flap assembly 5 covers the outer side of the oil cup 2. Figure 1-2As shown, when the range hood is not working, the oil cup 2 is hidden behind the flap assembly 5. When the oil cup 2 needs to be removed, it is only necessary to open the flange assembly 5 and pull the oil cup 2 outward to remove it. The oil cup 2 is located under the flap assembly 5. The flap can be opened by the drive assembly 6 to directly remove the oil cup 2. No additional decorative panels are required, saving costs.

[0051] In a preferred embodiment of the present invention, Figure 5 The illustrated range hood also includes a mounting bracket 7, which includes a mounting block 71 and an elastic sheet 72. The mounting block 71 is removably connected to the lower housing 12 and is configured to connect to the oil cup 2 in a slot. The elastic sheet 72 is connected to the slot and can abut against the oil cup 2. The oil cup 2 is mounted within the lower housing 12 via the mounting bracket 7, eliminating the need for a mounting platform or cover for the oil cup 2, resulting in a simple structure and low cost. Furthermore, the oil cup 2 can be provided with a connection portion that mates with the slot, allowing the oil cup 2 to be installed by simply inserting it into the slot. A limiting rib is provided on one side of the elastic sheet 72, near the interior of the slot. When the connection portion of the oil cup 2 is inserted into the slot, the limiting rib abuts against the connection portion. Otherwise, if the oil cup 2 is dislodged or shakes, this prevents oil stains from falling into the interior of the lower housing 12.

[0052] In a preferred embodiment of the present invention, Figure 5-6 The top plate 121 is shown as protruding upward to form a boss 1212. Boss 1212 has a cavity with an open bottom. Mounting block 71 is inserted into the cavity and fixedly connected to boss 1212. When molding lower housing 12, boss 1212 can be simply pressed out of top plate 121. The lug 7 is inserted into the cavity and fixed to boss 1212 by various means, such as bolting, welding, or gluing, without limitation.

[0053] In a preferred embodiment of the present invention, Figure 5-6 The boss 1212 shown also has a mounting hole 12120, to which the mounting lug 7 is bolted. The base plate 111 has a groove 1112 corresponding to the boss 1212, into which the boss 1212 can be inserted. The insertion of the boss 1212 into the groove 1112 prevents oil leakage caused by the connection between the mounting hole 12120 and the first and second oil leakage holes 1110, 1210. Furthermore, the coordination between the boss 1212 and the groove 1112 ensures proper alignment of the upper and lower housings 11, 12, facilitating assembly of the upper and lower housings 11, 12 and improving production efficiency.

[0054] In a preferred embodiment of the present invention, Figure 3 、 5The top wall of the upper housing 11 shown in FIG6 is provided with an air outlet 112. The air inlet end of the air outlet 112 is connected to the oil screen 8, and the air outlet end of the air outlet 112 is connected to the fan assembly 9. This allows oil smoke and other gases that enter the upper housing 11 to be discharged more quickly, improving the range hood's extraction efficiency and user experience.
