Description

Technical Field

[0001] This utility model relates to an oil fume purification device, and in particular to an installation structure for a range hood. Background Technology

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. It can quickly remove waste from the stove and fumes produced during cooking and exhaust them outdoors, reducing pollution and purifying the air.

[0003] Currently, range hoods are generally installed on the wall using a hanging assembly. For example, Chinese utility model patent application number 202221532601.3 discloses an installation device for a kitchen appliance, which includes: a hanging assembly for connecting to the external position where the kitchen appliance body is installed, including a hook for connecting to the corresponding installation part on the kitchen appliance body, the hook having a hook body formed thereon; and an adapter plate, which has a first mounting hole that is adapted to fit the hook body and can be engaged, and a connecting part for connecting to the corresponding installation part on the kitchen appliance body.

[0004] The following problems exist with range hoods that are simply hung on the wall using a suspension assembly: 1. There is a risk of them falling off; 2. Existing range hoods are designed to be compact and lightweight, resulting in small overall size and light weight. When installed on the wall, the overall vibration during operation can easily cause the smoke baffle to shake, and the kitchen lights reflected off the smoke baffle can easily dazzle customers; 3. There is a gap between the back of the range hood and the wall, allowing cooking fumes to easily seep up through the gap and condense on the wall, eventually flowing down the wall. Furthermore, the back of the range hood is difficult to clean. Utility Model Content

[0005] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a range hood installation structure that can prevent the range hood from falling off, effectively reduce the overall shaking of the range hood, and prevent oil fumes from rising from the back of the range hood, thus preventing the problem of oil stains that are difficult to clean.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a range hood installation structure, including a range hood and a hook, wherein the upper rear side of the range hood is connected to an external installation base through the hook, characterized in that: the range hood installation structure further includes a fixing plate disposed between the bottom of the range hood and the external installation base.

[0007] By adding a fixing plate at the bottom of the fume hood, and with the hooks on the fan frame providing restraint, the bottom of the fume hood is further secured to the wall, preventing the range hood from falling off. This effectively reduces the shaking of the entire range hood and isolates the fumes, preventing them from escaping through the gap between the back of the fume hood and the external mounting base, making cleaning easier.

[0008] In order to install hooks and fixing plates, the range hood includes a smoke collection hood, a fan frame installed above the smoke collection hood, and an oil cup installed at the bottom of the smoke collection hood. The hooks are installed between the fan frame and the external mounting base, and the fixing plates are installed between the bottom of the smoke collection hood and the external mounting base.

[0009] To form a fixing plate, the fixing plate includes a first connecting part that connects to an external mounting base, a second connecting part that connects to the bottom of the range hood, and a third connecting part for connecting the first connecting part and the second connecting part.

[0010] To ensure effective oil drainage and allow the rising fumes to condense at the bottom of the mounting plate and flow smoothly downwards, the first connecting part is fitted to the external mounting base, the second connecting part is fitted to the bottom of the range hood, and the first connecting part is higher than the second connecting part. The third connecting part includes a first segment and a second segment. The first segment is connected to the bottom of the first connecting part, and the other end of the first segment gradually extends forward from top to bottom. One end of the second segment is connected to the end of the first segment away from the first connecting part, and the other end of the second segment gradually extends upward from bottom to top. The end of the second segment away from the first connecting segment is connected to the rear end of the second connecting part. The connection between the first segment and the second segment is located inside the oil cup.

[0011] To further improve the oil guiding effect, the range hood includes a smoke collection hood and an oil cup set at the bottom of the smoke collection hood. The fixing plate is set between the bottom of the smoke collection hood and the external mounting base. The fixing plate also includes a flange for guiding oil set on the front side of the second connecting part. The flange gradually extends forward from top to bottom and is located inside the oil cup.

[0012] To ensure the oil guiding effect, so that the oil fumes rising from the bottom can flow down smoothly after condensing at the bottom of the fixed plate, the first section has an inclination angle α relative to the horizontal direction, where α ≥ 20°.

[0013] To ensure that the oil can flow smoothly into the oil cup, the distance between the connection between the first and second sections and the external mounting base is L, and the distance between the rear side of the oil cup and the external mounting base is M, where L > M.

[0014] To ensure smooth installation of the oil cup, the range hood includes a smoke collection hood and an oil cup located at the bottom of the smoke collection hood. The fixing plate is located between the bottom of the smoke collection hood and the external mounting base. The top of both sides of the oil cup has hanging ears extending towards the inside of the oil cup. The bottom of the smoke collection hood is provided with a hanging component that engages with the hanging ears. The distance between the bottom of the hanging component and the bottom of the smoke collection hood is K. The distance between the connection point of the first and second segments and the bottom of the smoke collection hood is N, where N < K.

[0015] Compared with the prior art, the advantages of this utility model are as follows: by adding a fixing plate to the bottom of the fume hood, and with the constraint of hooks on the fan frame, the bottom of the fume hood is further constrained with respect to the wall, thereby fixing the bottom and preventing the range hood from falling off. This effectively reduces the shaking of the entire range hood and isolates the fumes, preventing them from rising from the gap between the back of the fume hood and the external mounting base, making cleaning and maintenance easier.

[0027] The first connecting part 301 is fitted to the external mounting base 100. The second connecting part 302 is fitted to the bottom of the smoke hood 1. The first connecting part 301 and the second connecting part 302 can be connected to the external mounting base 100 and the smoke hood 1 respectively by screws. The first connecting part 301 is higher than the second connecting part 302. The third connecting part 303 includes a first segment 3031 and a second segment 3032. The first segment 3031 is connected to the bottom of the first connecting part 301, and the other end of the first segment 3031 gradually extends forward from top to bottom. One end of the second segment 3032 is connected to the end of the first segment 3031 away from the first connecting part 301. The other end of the second segment 3032 gradually extends upward from bottom to top, and the end of the second connecting segment 3032 away from the first connecting segment 3031 is connected to the rear end of the second connecting part 302. The connection between the first segment 3031 and the second segment 3032 is located inside the oil cup 3. To ensure the oil guiding effect, so that the oil fumes rising from the bottom can flow down smoothly after condensing at the bottom of the fixed plate 300, the first section 3031 has an inclination angle of α relative to the horizontal direction, where α ≥ 20°.

[0028] The fixing plate 300 also includes a flange 304 for guiding oil, which is provided on the front side of the second connecting part 302. The flange 304 extends gradually from top to bottom towards the front and is located inside the oil cup 3.
