Description

Technical Field

[0001] This utility model relates to an oil fume purification device, and more particularly to an oil fume extractor. Background Technology

[0002] Range hoods have become an indispensable kitchen appliance in modern homes. They operate on the principles of fluid dynamics, using a centrifugal fan inside to draw in cooking fumes and a filter to remove some grease particles. The centrifugal fan consists of a casing, an impeller housed within the casing, and a motor that drives the impeller. As the impeller rotates, a negative pressure is generated at the center of the fan, drawing in the cooking fumes from below. After being accelerated by the fan, the fumes are collected by the casing and guided outdoors.

[0003] To prevent cooking fumes from escaping and thus improve the fume extraction effect, traditional range hoods usually have a smoke guide plate at the air inlet to guide the flow of cooking fumes. Adding a smoke guide plate can block the escape of cooking fumes and improve the fume extraction effect. Existing top-mounted range hoods usually include an upper box and a smoke collection hood installed at the bottom of the upper box. The upper box contains a fume extraction fan, and the smoke guide plate is installed at the bottom of the smoke collection hood. The smoke guide plate is usually fixed to the bottom of the smoke collection hood by a bracket. For example, the Chinese invention patent No. 201910431483.3 (authorized public number CN 110160099 B) discloses a range hood and integrated cooktop. The range hood has a smoke guide plate below the air inlet of the smoke collection hood, and a rotating bracket is located on the side of the smoke guide plate facing the air inlet. The rotation axis formed by the rotating shaft is arranged along the front-back direction of the smoke guide plate and is located in the middle of the smoke guide plate. A drive mechanism is used to drive the rotating shaft to rotate, thereby causing the smoke guide plate and the rotating bracket to rotate around the rotating shaft. One end of the rotating shaft is connected to the drive mechanism, and the other end is connected to the rotating bracket. Alternatively, common smoke guide plates are fixed using ordinary spring clips, which mainly rely on spring-loaded balls and other structures for locking. That is, the connection between the smoke guide plate and the smoke collection hood is fixed by clips and claws. The steel balls on the clips rely on the elastic force provided by the spring to contact the claws. The exterior is fixed and decorated with plugs and decorative plug stickers. Because the top plate of the smoke hood is flat and large, the above-mentioned smoke guide plate installation structure does not solve the problem of top plate twisting, which affects the overall stability of the range hood. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a range hood that can avoid the twisting phenomenon at the four corners of the top plate of the smoke collection hood, in view of the above-mentioned existing technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a range hood, including an upper box and a smoke collection hood installed at the bottom of the upper box, a smoke guide plate installed on the smoke collection hood, the smoke guide plate being fixed to the top plate of the smoke collection hood by a mounting bracket, and an air inlet being opened in the middle of the top plate of the smoke collection hood, characterized in that: the mounting bracket is located on the left and right sides of the air inlet and is symmetrically distributed on the left and right, and the mounting bracket is inclined outward from front to back.

[0006] To improve the bending resistance of the mounting bracket, preferably, the mounting bracket has a bracket body, the top of the bracket body has a first bending portion, the bottom of the bracket body has a second bending portion, the first bending portion is fixed to the top plate of the smoke collection hood, and the second bending portion is installed on the smoke guide plate.

[0007] To further enhance the structural strength of the mounting bracket, the bending directions of the first and second bending portions are opposite.

[0008] To ensure the mounting bracket can be fixed to the lamp holder and the smoke guide plate, the front side of the bracket body has a third bend and a fourth bend. The lamp holder is installed inside the front side of the smoke hood, and the third bend is fixed to the lamp holder. A connecting bracket is fixed to the back of the smoke guide plate, and the fourth bend is fixed to the connecting bracket. This design further improves the stability of the smoke guide plate mounting structure.

[0009] In order to fasten the smoke guide plate to the mounting bracket, the back of the smoke guide plate is fixed with a locking foot, and the second bent part is provided with a locking hole, and the locking foot is inserted into the locking hole.

[0010] To enhance the corner strength of the mounting bracket and prevent top plate deformation when the entire machine falls, the top of the bracket body has a forward-extending extension that extends forward from the front plate of the upper housing.

[0011] To enhance the corner strength of the mounting bracket and prevent top plate deformation when the entire unit falls, a light bracket is installed inside the front side of the smoke hood. The top of the bracket body has a forward-extending extension that extends forward from the front plate of the upper housing and extends above the light bracket.

[0012] As a preferred embodiment of any of the above schemes, when the mounting bracket is installed, the first bending portion is arranged horizontally, and the second bending portion is arranged obliquely downward from front to back.

[0013] More preferably, the inclination angle of the second bent portion relative to the horizontal plane is the same as the inclination angle of the smoke guide plate relative to the horizontal plane.

[0014] Further preferably, the inclination angle of the smoke guide plate relative to the horizontal plane is the same as the inclination angle of the lower edge of the smoke collection hood relative to the horizontal plane.

[0015] Compared with existing designs, the advantages of this utility model are as follows: the guide plate of the range hood is fixed to the top plate of the smoke collection hood by the mounting bracket. The mounting bracket is located on the left and right sides of the air inlet of the top plate of the smoke collection hood and is symmetrically distributed. The mounting bracket is distributed from front to back and outward, which can not only ensure that the mounting bracket is invisible to the user, but also solve the problem of the top plate of the smoke collection hood twisting, and improve the structural strength of the top plate of the smoke collection hood.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 6 As shown, the range hood in this embodiment includes an upper housing 1 and a smoke collection hood 2 installed at the bottom of the upper housing 1. A smoke guide plate 3 is installed on the smoke collection hood 2, and the smoke guide plate 3 is fixed to the top plate 21 of the smoke collection hood by a mounting bracket 4. An air inlet 22 is opened in the middle of the top plate 21 of the smoke collection hood. The mounting bracket 4 is located on the left and right sides of the air inlet 22 and is symmetrically distributed. The mounting bracket 4 is inclined outward from front to back, and the outward inclination angle can preferably be set between 20° and 40°. In this way, on the one hand, the mounting bracket is completely covered by the smoke guide plate and cannot be seen by the user, and on the other hand, the four corners of the top plate 21 of the smoke collection hood are prevented from twisting.

[0024] The mounting bracket 4 in this embodiment has a bracket body 40. The top of the bracket body 40 has a first bent portion 41, and the bottom of the bracket body 40 has a second bent portion 42. The first bent portion 41 is fixed to the top plate 21 of the smoke hood. In this embodiment, the mounting bracket 4 and the top plate 21 of the smoke hood are welded together and cannot be disassembled by the user. The second bent portion 42 is installed on the smoke guide plate 3. In order to improve the structural strength of the mounting bracket, the bending directions of the first bent portion 41 and the second bent portion 42 are opposite. The use of the first bent portion 41 and the second bent portion 42 can improve the bending resistance of the mounting bracket 4. In the installed state of the mounting bracket 4, the first bent portion 41 is arranged horizontally, and the second bent portion 42 is arranged obliquely downward from front to back. Moreover, the inclination angle of the second bent portion 42 relative to the horizontal plane is the same as the inclination angle of the smoke guide plate 3 relative to the horizontal plane, and also the same as the inclination angle of the lower edge of the smoke hood 2 relative to the horizontal plane.

[0025] The front side of the bracket body 40 has a third bend 43 and a fourth bend 44. A lamp bracket 5 is installed inside the front side of the smoke hood 2. The third bend 43 is fixed to the lamp bracket 5 with screws (not shown in the figure). A connecting bracket 31 is fixed to the back of the smoke guide plate 3, and the fourth bend 44 is fixed to the connecting bracket 31 with screws (not shown in the figure). The use of the third bend 43 and the fourth bend 44 makes the installation structure of the smoke guide plate 3 and the mounting bracket 4 more robust.

[0026] The top of the bracket body 40 has a forward-extending extension 45, which extends forward from the front plate 11 of the upper housing 1 and extends above the lamp bracket 5. The extension 45 can improve the corner strength of the mounting bracket and prevent the top plate 21 of the smoke hood from deforming when the whole machine is dropped.

[0027] In this embodiment, a retaining foot 32 is fixed to the back of the smoke guide plate, such as... Figure 4 As shown, there are four locking feet 32 ​​distributed on the left and right sides of the smoke guide plate. The second bent part 42 of the mounting bracket 4 on the left and right sides has two locking holes 421 respectively, and the locking feet 32 ​​are inserted into the corresponding locking feet 32 ​​holes.

[0028] This range hood can be controlled by a voice module, which is equipped with a control module, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the range hood to perform corresponding operations, thereby realizing intelligent control of the range hood and improving the user experience.

However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
