Description

Technical Field

[0001] The utility model relates to the technical field of kitchen household appliances, in particular to an oil mesh installation structure and a range hood applying the installation structure. Background Art

[0002] A range hood is a kitchen appliance installed above a gas stove, which can quickly extract the oil fume generated during cooking, thus preventing the interior of the kitchen from being polluted by oil fume; an oil mesh is usually provided at the smoke inlet of the range hood. After long-term use, a large amount of oil stains will adhere to the oil mesh, making it difficult to clean. Generally, the oil mesh of a range hood is roughly rectangular in structure. Such an oil mesh has a large volume and is installed on the range hood using bolts. When cleaning, the bolts need to be disassembled, which is rather inconvenient; and without disassembling the oil mesh, only its outer surface can be wiped during daily use, and the inner side of the oil mesh cannot be cleaned, easily forming stubborn stains.

[0003] Therefore, currently, there are range hoods that are convenient for disassembling the oil filter mesh. For example, the "Range Hood with Layer-by-Layer Purification Function" disclosed in the Chinese utility model patent with the application number CN202222807556.4. In this patent, an installation groove is opened on the lower surface of the smoke collecting hood. An installation frame is installed inside the installation groove, and an oil filter mesh is fixedly connected inside the installation frame. The installation frame and the installation groove are detachably connected: a limiting card slot is symmetrically opened at the lower part of the installation frame, and a limiting block adapted to the limiting card slot is provided on the inner bottom wall of the installation groove; sliding limiting structures are symmetrically provided on the installation frame, and limiting circular grooves are symmetrically opened on the inner wall of the installation groove. The sliding limiting structure includes a limiting rod that can slide into the limiting circular groove. When the oil filter mesh needs to be disassembled, the limiting rod is removed from the inside of the limiting circular groove and the limitation between the limiting card slot and the limiting block is released, and the installation frame and the oil filter mesh can be disassembled, thus facilitating the cleaning of the oil filter mesh and solving the problem that the oil filter mesh is not easily disassembled and cleaned due to the fixed connection method.

[0004] However, the above technical solution still has the following deficiencies: only a pair of sliding limiting structures are symmetrically arranged between the installation groove and the installation frame. After removing the limiting rod from the limiting circular groove, only the installation frame and the oil mesh can be taken down for cleaning. It is rather inconvenient to take down the installation frame and the oil mesh as a whole for cleaning, and the cleaning method of the oil mesh is single. Summary of the Utility Model

[0005] The first technical problem to be solved by the utility model is to provide an oil mesh installation structure that is convenient for cleaning the oil mesh and has various cleaning methods according to the current situation of the prior art.

[0006] The second technical problem to be solved by the utility model is to provide a range hood applying the above oil mesh installation structure according to the current situation of the prior art.

[0007] The technical solution adopted by the present utility model to solve the above first technical problem is as follows: This oil screen installation structure includes an oil screen, a mounting frame, and a mounting plate provided on the range hood and having a smoke inlet. The oil screen is installed on the mounting frame, and the mounting frame is installed at the smoke inlet. A limiting hole is provided on the inner side wall of the smoke inlet of the mounting plate, and a limiting device is provided on the mounting frame corresponding to the limiting hole. There are two pairs of the limiting devices, and each limiting device includes a limiting shaft that can penetrate into or withdraw from the limiting hole. The extension lines of the two limiting shafts in each pair of limiting devices coincide with each other in the length direction. In the state where the two limiting shafts in one pair of limiting devices withdraw from the corresponding limiting holes, the mounting frame can rotate with the straight line where the limiting shafts of the other pair of limiting devices are located as the axis.

[0008] Preferably, the two limiting holes corresponding to each pair of limiting devices are symmetrically arranged on the left inner wall and the right inner wall of the smoke inlet. This structure enables the mounting frame to rotate upward or downward, and rotating the mounting frame downward is more convenient for users to clean the inner side of the oil screen.

[0009] In order to reduce the possibility of the limiting device withdrawing from the limiting hole, the limiting device includes a chute and a limiting shaft partially located in the chute. The limiting shaft penetrates through the side wall of the chute so as to be able to penetrate into the limiting hole, and a pushing structure is connected to the inner end of the limiting shaft to keep the outer end of the limiting shaft always in a tendency to penetrate into the limiting hole.

[0010] In order to facilitate the user to slide the limiting shaft, the chute is opened on the front side of the mounting frame.

[0011] In order to reduce the pollution of the pushing structure by oil fumes and improve the aesthetics, a movable cavity for hiding the pushing structure is provided inside the chute.

[0012] In order to facilitate the connection between the first elastic member and the limiting shaft, the pushing structure includes a first elastic member and a movable plate. The inner end of the first elastic member is connected to the inner wall of the movable cavity, and the first elastic member, the movable plate, and the limiting shaft are connected in sequence from the inside to the outside.

[0013] In order to limit the movement range of the first elastic member and extend the service life of the first elastic member, the diameter of the movable cavity is slightly larger than the diameter of the first elastic member.

[0014] In order to facilitate the user to slide the limiting shaft, the limiting device further includes a connecting rod and a slider slidably disposed in the chute. The pushing structure, the connecting rod, the slider, and the limiting shaft are connected in sequence from the inside to the outside.

[0015] Preferably, an operation groove is provided on the surface of the slider.

[0016] In order to further reduce the pollution of the driving structure by oil fumes, a relief hole through which the connecting rod can pass is provided in the movable cavity, and the sliding groove is communicated with the movable cavity through this relief hole. The diameter of the relief hole is slightly larger than the diameter of the connecting rod.

[0017] In order to let the user know that the limit shaft slides to the target position and prevent the limit shaft from sliding out of the limit hole, a locking structure for locking the limit shaft is provided in the limit hole.

[0018] Preferably, a connecting portion in the shape of a frustum of a cone is provided at the outer end of the limit shaft, and the locking structure locks this connecting portion. The connecting portion in the shape of a frustum of a cone facilitates the locking by the locking structure, and the connecting portion in the shape of a frustum of a cone can rotate within the locking structure without affecting the flipping of the mounting bracket.

[0019] The technical solution adopted by the present utility model to solve the above-mentioned second technical problem is as follows: This range hood is applied with the above-mentioned oil mesh installation structure.

[0020] Compared with the prior art, the advantages of the present utility model are as follows: Two pairs of limit devices can slide into the limit holes on the mounting plate. When the connection between one pair of limit devices and the corresponding limit hole is released, the mounting bracket can rotate around the other pair of limit devices, facilitating the user to perform daily cleaning on the inner side of the oil mesh on the mounting bracket. The cleaning is convenient and stubborn stains are not easily formed; and after the connection between the two pairs of limit devices and the corresponding limit holes is released, the mounting bracket can be detached from the mounting plate, facilitating the user to perform in-depth cleaning on the oil mesh. The oil mesh can be cleaned daily and in-depth, and the cleaning methods are diverse. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] like Figures 1 to 7 The figure shows a preferred embodiment of the oil net installation structure of the utility model, which includes an oil net 1, a mounting frame 2 and a mounting plate 3 arranged on the range hood and having a square smoke inlet 3a. The oil net 1 is installed on the mounting frame 2, and the mounting frame 2 is installed at the smoke inlet 3a of the mounting plate 3.

[0030] The mounting frame 2 is detachably connected to the mounting plate 3. Two pairs of limiting holes 31 are symmetrically arranged on the left and right inner walls of the smoke inlet 3a of the mounting plate 3. Correspondingly, two pairs of limiting devices 21 are symmetrically arranged on the mounting frame 2. Each limiting device 21 can be inserted into or out of the corresponding limiting hole 31. When one pair of limiting devices 21 is out of the corresponding limiting hole 31, the mounting frame 2 can be turned over around the other pair of limiting devices 21. Figure 1 As shown, by removing the pair of limiting devices 21 located at the lower side from the corresponding limiting holes 31, the mounting frame 2 can be flipped upward; similarly, by removing the pair of limiting devices 21 located at the upper side from the corresponding limiting holes 31, the mounting frame 2 can be flipped downward.

[0031] like Figures 2 to 4 As shown, the limiting device 21 includes a slide groove 211, a limiting shaft 212, a connecting rod 213 and a slider 214. The slide groove 211 is opened on the front side of the mounting frame 2. A slider 214 that can slide along the slide groove 211 is provided in the slide groove 211. The inner end of the slider 214 is connected to the connecting rod 213, and the outer end of the slider 214 is connected to the limiting shaft 212. The limiting shaft 212 passes through the side wall of the slide groove 211 so as to be inserted into the above-mentioned limiting hole 31.

[0032] In addition, an active cavity 23 is provided on the inner side of the slide groove 211, and a pushing structure 22 is hidden in the active cavity 23. The pushing structure 22 enables the outer end of the limiting shaft 212 to always maintain a tendency to penetrate into the limiting hole 31. Specifically, the pushing structure 22 includes a first elastic member 221 and a movable plate 222. The inner end of the first elastic member 221 is connected to the inner wall of the active cavity 23, and the first elastic member 221, the movable plate 222, the connecting rod 213, the slider 214 and the limiting shaft 212 are sequentially connected from the inside to the outside; the active cavity 23 is provided with a clearance hole 231 connected to the slide groove 211, and the connecting rod 213 can pass through the clearance hole 231, and the diameter of the clearance hole 231 is slightly larger than the diameter of the connecting rod 213. The user slides the slider 214 inward, and the slider 214 compresses the first elastic member 221, and at the same time the slider 214 drives the limiting shaft 212 to disengage from the limiting hole 31. Figure 5When the user does not apply force to the slider, the first elastic member 221 changes from the compressed state to the extended state and then pushes the slider outwards. The limiting shaft 212 penetrates into the limiting hole 31 under the push of the slider, as shown in Figure 4 .

[0033] Among them, the first elastic member 221 is a spring; in order to limit the movement range of the first elastic member 221 and extend the service life of the first elastic member 221, the diameter of the activity cavity 23 is slightly larger than the diameter of the first elastic member 221. In this embodiment, when viewed from the front of the mounting bracket 2, only the chute 211, the connecting rod 213, the slider 214, and the limiting shaft 212 can be seen, and the first elastic member 221 and the movable plate 222 are hidden in the activity cavity 23, making the structure more beautiful. In addition, an operation groove 215 is provided on the surface of the slider 214.

[0034] In order to let the user know that the limiting shaft slides to the target position to improve the operation feeling and further prevent the limiting shaft from sliding out of the limiting hole, a locking structure 32 for locking the limiting shaft 212 is provided in the limiting hole 31; among them, a connecting portion 2121 in the shape of a frustum of a cone is provided at the outer end of the limiting shaft 212, and the locking structure 32 locks the connecting portion 2121. The frustum-shaped connecting portion 2121 facilitates the locking of the locking structure 32, and the frustum-shaped connecting portion 2121 can rotate in the locking structure 32 without affecting the flipping of the mounting bracket 2.

[0035] The present utility model also provides a range hood applying the above oil screen installation structure.
