[0029] like Figure 1-3 As shown, a hinged range hood frame structure includes a support 10, with a flow guiding component 20 at its lower part and a purification component 30 at its upper part, wherein:

[0030] The bracket 10 is an L-shaped bracket, including a longitudinal plate 11 and a transverse plate 12, and sealing plates 13 are provided on two opposite parallel side walls; the bracket 10 is provided with a support plate 14 parallel to the transverse plate 12, and the support plate 14 and the two sealing plates 13 divide the bracket 10 into an upper cavity and a lower cavity. The flow guiding component 20 is provided in the lower cavity, and the purification component 30 is provided in the upper cavity. The upper cavity has one or more exhaust slots on its wall.

[0031] The flow guiding assembly 20 includes a flow guiding plate 21 inclined between the two ends of the longitudinal plate 11 and the support plate 14. The two ends of the flow guiding plate 21 are respectively connected to a sealing plate 13. An oil box 22 is provided at the lower end of the lower cavity.

[0032] The purification assembly 30 includes a purification box 31 mounted on the support plate 14. The purification box 31 contains a plurality of purification devices 32 connected in sequence. One of the purification devices 32 is connected to an air intake channel, the opening of which is located on the support plate 14. A door panel 33 is hinged to the front end of the transverse plate 12. The door panel 33 is equipped with a control center that is electrically connected to a power source. The control center and the plurality of purification devices 32 are each equipped with a connector 34 that can be matched, connected, and conduct circuits.

[0033] This invention hinges a door panel 33 at the front end of the bracket 10 and provides a control center and connector 34 connected to the power supply on the door panel 33. Without disassembling any parts or manually connecting the power supply, the power supply connection of the purification device 32 can be directly disconnected when the door panel 33 is opened. This makes it convenient for users to view or replace the internal purification devices 32. It is safe to use and easy to operate.

[0034] Furthermore, the door panel 33 or the guide plate 21 is provided with one or more slots, and the guide plate 21 or the door panel 33 is provided with a plurality of buckles 25 that can match them one by one.

[0035] Understandably, the matching snap-on and slot-locking structure ensures that the door panel 33 is properly locked when closed, and that the connector 34 on the door panel 33 can maintain continuous and stable contact with the connector 34 on the purification device 32, thereby ensuring that the range hood maintains a continuous and good purification effect.

[0036] Furthermore, the guide plate 21 includes two or more guide plates 23 arranged side by side, and each guide plate 23 is provided with a plurality of parallel ventilation grooves 24 extending toward the oil box 22.

[0037] Furthermore, such as Figure 4-5As shown, each guide plate 23 includes an outer plate 1 and an inner plate 2 with a frame-shaped structure and matching and fastening of the four walls. Each outer plate 1 and each inner plate 2 has a plurality of ventilation slots 24 arranged alternately. Each ventilation slot 24 has an oil baffle 3 symmetrically provided on two opposite side walls, extending outward at an inclined angle. The end of each oil baffle 3 is located in a guide plate 23. Each guide plate 23 has a buckle 25.

[0038] Understandably, the staggered ventilation slots 24 on the inner plate 2 and outer plate 1 can prolong the time that the oil fumes stay in the guide plate 21, and the oil baffle plate 3 can initially cool down the high-temperature oil fumes and guide the precipitated oil mist to the oil box 22 below it, thus achieving the first purification of the oil fumes, reducing the purification load of subsequent purification devices, extending their maintenance cycle and service life.

[0039] Furthermore, the end of the longitudinal plate 11 is provided with a horizontally or inclined diversion plate 15. The side ends of the diversion plate 15 are respectively connected to the guide plate and the two sealing plates 13. The bottom end of the diversion plate 15 is provided with the oil box 22. The diversion plate 15 is provided with several through holes above the oil box 22.

[0040] In this embodiment, the diversion plate 15 is horizontally arranged and serves as a connection and fixation mechanism, and the oil box 22 is installed at its lower end, which facilitates disassembly and assembly and does not affect the stability of other structural components.

[0041] As a specific application of the above embodiments:

[0042] like Figure 1-2 As shown, an easy-to-clean range hood includes the hinged range hood frame structure described in the above embodiments. Each of the purification devices 32 is slidably mounted on the purification box 31. Elastic support rods 40 are provided on both sides of several purification devices 32 between the door panel 33 and the bracket 10. A fan 50 is provided on the horizontal plate 12, and the air inlet of the fan 50 is connected to an exhaust slot.

[0043] The present invention provides an elastic support rod 40 and slides the purification device 32 onto the purification box 31, so that it can be automatically supported and fixed after the door panel 33 is opened, so that the purification device 32 can be safely and quickly taken out for cleaning or replacement. It is safe to use and easy to operate.

[0044] In some embodiments of the present invention, the purification box 31 is provided with a slide and / or partition that matches each of the purification devices 32.

[0045] Understandably, the installation of slides or partitions can guide the loading direction and position of different purification devices 32, and ordinary users can directly perform disassembly and assembly operations without having to consider the problem of oil fume airflow blockage after loading.

[0046] In application, appropriate slides or partitions can be set according to different types of purification devices 32, and necessary pipelines can be set at appropriate positions in the purification box 31 or partitions to ensure that the airflow flows sequentially and unidirectionally between each purification device 32 under the drive of the fan 50. This structural setting is common knowledge to those skilled in the art, and its specific structure will not be described in detail here.

[0047] Furthermore, the connector 34 includes a plurality of matched first conductive elements and second conductive elements, each of the first conductive elements being disposed on the control center, and each of the second conductive elements being disposed on a purification device 32.

[0048] Furthermore, the door panel 33 is also equipped with a display screen 35 and a warning device 36, both of which are electrically connected to the power supply and the control center.

[0049] In application, when the second conductive component cannot be tightly connected to the first conductive component after the panel 33 is fastened, resulting in an abnormal operation of the purification device 32, the control center will receive a feedback signal and instruct the warning device 36 to issue an alarm signal to remind the user, ensuring that the range hood always maintains a stable working state and purification effect.

[0050] The above does not limit the technical scope of the present invention in any way. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the technical scope of the present invention.
