Description

Technical Field

[0001] The invention relates to the technical field of range hoods, and in particular to a smoke guide plate assembly and a range hood. Background Art

[0002] At present, the common methods of disassembling and assembling the smoke guide plate of the range hood on the market include magnetic steel attraction, plastic bead and metal lock. If the magnetic steel attraction fixing method is adopted, the installation position is usually located at the bottom of the smoke guide plate, and the operator often needs to observe from the side whether it is correctly hung. The magnet attraction position is prone to installation dislocation due to the magnet's misattraction, causing inconvenience to the installer. In addition, after long-term use, the magnetic force of the magnet will gradually decay so that it cannot resist the gravity and cause the smoke guide plate to loosen. If the installation method of plastic bead or metal lock is adopted, after the smoke guide plate is repeatedly disassembled and assembled, the locking mechanism will be worn and there is a risk of loose installation and loosening. In addition, the disassembly and assembly structures of other existing smoke guide plates generally have defects such as too many parts, relatively complex structure, fixed disassembly and assembly process, which is difficult for one person to operate, and relatively large installation space.

[0003] The prior art discloses an easily detachable oil guide plate type range hood, comprising a housing, a fan installed in the housing, an oil guide plate connected to the housing at both ends, and an oil cup arranged below the oil guide plate, wherein one end of the oil guide plate is connected to the housing through a rotary mechanism, and the other end is connected to the housing through a locking mechanism. The locking mechanism comprises a housing suitable for connecting to the oil guide plate, a spring arranged in the housing, a clip used in conjunction with the spring and snapped with the housing, and the clip comprises a snap-fitting portion suitable for snapping with the housing and a pressing portion arranged perpendicularly to the snap-fitting portion. During installation, since the locking mechanism is installed on the back of the oil guide plate, it is difficult to accurately determine the position during disassembly, and it can only be done by manual blind exploration, which is inconvenient for actual operation. During use, the oil guide plate needs to be frequently disassembled and cleaned due to the adhesion of oil stains, and needs to be disassembled and assembled repeatedly, while the oil guide plates in the prior art are not conducive to repeated disassembly and assembly.

[0057] Example 1

[0058] This embodiment provides a smoke guide plate assembly, such as Figure 1 -10, which is suitable for installation on the machine body 1, and includes a rotating bracket and a smoke guide plate 4.

[0059] The rotating bracket is rotatably connected to the body 1, and the rotating bracket extends out of the body 1. In this embodiment, the rotating bracket includes a mounting base 2 and a bearing base 3, wherein two mounting bases 2 are provided and are connected to the rotating shaft of the body 1 at intervals, including a first end suitable for connecting to the rotating shaft in the body 1, and a second end located outside the body 1, such as Figure 3 and Figure 8 As shown, the first end and the second end form an L shape, the bearing base 3 is connected to the second end of the mounting base 2, and the size of the first end is smaller than the size of the second end. In order to facilitate the mounting base 2 to be conveniently mounted on the rotating shaft in the body 1, the size of the first end of the mounting base 2 needs to be smaller, so that the user can adjust the angle of the mounting base 2 at any time. At the same time, in order to ensure the bearing strength of the mounting base 2 on the bearing base 3, the mounting base 2 is provided with at least two, and is connected to the rotating shaft at intervals.

[0060] The smoke guide plate 4 is detachably connected to the rotating bracket via a connecting structure 5, and the connecting structure 5 is connected to the portion of the rotating bracket extending outside the body 1. Preferably, the connecting structure 5 is connected to the side portion of the rotating bracket extending outside the body 1. In this embodiment, the smoke guide plate 4 is a rectangular parallelepiped structure, and the portion where the rotating bracket is connected to the smoke guide plate 4 is also a rectangular parallelepiped structure. Preferably, the connecting structure 5 is connected to the two sides of the rotating bracket extending outside the body 1, and the two sides correspond to the short sides of the rectangular parallelepiped structure. Of course, in an alternative embodiment, when the smoke guide plate 4 presents other shapes, the connecting structure 5 is connected to the side portion of the rotating bracket extending outside the body 1 for easy observation by the human eye.

[0061] The smoke guide plate 4 includes a body 41 and a connecting portion 42 protruding from the body 41. The rotating bracket is provided with a positioning space 33 suitable for accommodating the connecting portion 42. When the connecting portion 42 is located in the positioning space 33, the rotating bracket supports the body 41. The positioning space 33 can position the connecting portion 42 of the smoke guide plate 4, and there is no need to repeatedly adjust and calibrate the position of the smoke guide plate 4, which facilitates the installation of the smoke guide plate 4. The positioning space 33 of this embodiment is a positioning hole that passes through the rotating bracket, so that the rotating bracket is a hollow frame structure, which can reduce the weight of the rotating bracket and facilitate manual installation of the rotating bracket. Of course, as an alternative embodiment, the positioning space 33 is a positioning groove.

[0062] The supporting base 3 includes two first side walls 31 arranged opposite to each other, the positioning space 33 is arranged between the two first side walls 31, a first hole is penetrated through the first side wall 31, and a second hole is arranged at a position opposite to the first hole on the connecting part 42, and the connecting structure 5 connects the rotating bracket with the connecting part 42 by connecting in the first hole and the second hole.

[0063] In this embodiment, the connecting structure 5 includes a pin structure slidably disposed in the first hole, and the pin structure has a first position of being inserted into the second hole to connect the smoke guide plate 4 to the rotating bracket, and a second position of leaving the second hole to separate the smoke guide plate 4 from the rotating bracket.

[0064] One end of the pin structure that is suitable for being inserted into the second hole is the first end. A step surface is provided on the pin structure near the first end. A spring 52 is provided between the step surface and the first side wall 31 of the rotating bracket.

[0065] Specifically, the pin structure includes a guide column 51 and a screw 53. The guide column 51 is provided with the step surface near the first end. The guide column 51 is provided with the spring 52. One end of the spring 52 abuts against the first side wall 31, and the other end abuts against the step surface. The end of the guide column 51 located at the first side wall 31 is the second end. The second end is provided with a threaded hole. The screw 53 is arranged outside the side wall and connected to the threaded hole. Since the contact area of ​​the head of the screw 53 is small, the human hand will feel uncomfortable when pulling the screw 53. Therefore, in order to facilitate the movement of the pin structure, the pin structure also includes a sliding paddle 54 arranged between the screw 53 and the guide column 51. The sliding paddle 54 has a large contact area with the human hand. In this way, when the pin structure needs to be moved, the pin structure can be moved by toggling the sliding paddle 54.

[0066] In this embodiment, if Figure 4 As shown, the supporting substrate 3 includes a plate-like structure in the form of a rectangular ring, the outer edge of the plate-like structure extends upward to form a rectangular ring-shaped side wall, the short side of the rectangular ring-shaped side wall is the first side wall 31, and the short side of the inner edge of the plate-like structure also extends upward to form a second side wall 32, and the positioning space 33 is formed between the two opposite second side walls 32, and the second side wall 32 is provided with a third hole connected to the second hole. When the pin structure is in the second position, the first end of the pin structure is located in the third hole. This arrangement makes it possible for the pin structure to be pulled out of the second hole. Figure 7 As shown, the pin structure is located in the first hole and the third hole, the force on the pin structure is balanced, and no shaking or swinging occurs, which is conducive to the insertion and removal of the pin structure in the second hole.

[0067] When installing the pin structure, first pass the second end of the guide column 51 through the third hole, put the spring 52 on the outside of the guide column 51, then move the guide column 51 so that its second end passes through the first hole, put the sliding paddle 54 on the outside of the screw 53, and tighten the screw 53 in the threaded hole.

[0068] To ensure that the connecting structure 5 firmly connects the smoke guide plate 4 to the rotating bracket, the connecting structure 5 also includes a snap structure connecting one end of the smoke guide plate 4 located outside the body 1 and the rotating bracket, and the snap structure includes a snap 6 arranged on the end of the smoke guide plate 4 located outside the body 1, and a snap hole 7 arranged on the rotating bracket, and the snap 6 is suitable for extending into the snap hole 7.

[0069] When installing the smoke guide plate assembly on the body 1, first fix the mounting base 2 of the rotating bracket to the rotating shaft inside the body 1, then fix the supporting base 3 to the mounting base 2 by screws, and insert the buckle 6 on the end of the smoke guide plate 4 located outside the body 1 into the clamping hole 7 on the outermost end of the rotating bracket, rotate the smoke guide plate 4 so that the connecting part 42 on the smoke guide plate 4 is accommodated in the positioning hole on the supporting base 3. At this time, the first hole and the third hole on the supporting base 3 are aligned with the second hole on the smoke guide plate 4. Before the connecting part 42 is accommodated in the positioning hole, move the sliding paddle 54 so that the connecting part 42 can smoothly enter the positioning hole, and then release the sliding paddle 54. Under the action of the restoring force of the spring 52, the guide column 51 will be inserted into the second hole, and the rotating bracket will be fixedly installed on the supporting base 3. When the smoke guide plate 4 is greasy and needs to be cleaned after use, the sliding paddle 54 is moved to make the guide column 51 leave the second hole. At this time, the end of the smoke guide plate 4 close to the body 1 can be lifted up, and then the buckle 6 on the front end of the smoke guide plate 4, that is, the end away from the body 1, is disengaged from the clamping hole 7 on the supporting base 3. The disassembly is completed and the smoke guide plate 4 is cleaned. Since it is only necessary to disassemble the smoke guide plate 4 from the rotating bracket without disassembling the rotating bracket, the smoke guide plate assembly is convenient for repeated disassembly and assembly of the smoke guide plate 4, and is convenient for users to install and use.

[0070] As a first replaceable implementation of the above embodiment, the connecting structure 5 can adopt threaded fasteners. Since the connecting structure 5 is connected to the part of the rotating bracket extending outside the body 1, it still has the advantage of convenient disassembly and assembly compared with the prior art, which is conducive to the repeated disassembly and assembly of the smoke guide plate 4 on the mounting bracket.

[0071] As a second alternative implementation of the above embodiment, the connecting structure 5 is connected to the top or bottom of the rotating bracket.

[0072] As a third alternative implementation of the above embodiment, two groups of connection structures 5 are connected to the same side of the connection portion 42 of the rotating bracket and the smoke guide plate 4, so that the rotating bracket and the smoke guide plate 4 do not need to be connected by the buckle 6.

[0073] As a fourth alternative implementation of the above embodiment, the number of the mounting bases 2 is 3 or more.

[0074] Example 2

[0075] This embodiment provides a range hood, comprising a body 1, and the smoke guide plate assembly provided in the above embodiment is installed on the body 1. The smoke guide plate 4 of the range hood can be easily removed from the body 1 for cleaning, which is convenient for users to use.

[0076] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
