TECHNICAL FIELD
[0001] The present application relates to the technical field of range hood motor installation, in particular to a silent range hood motor installation structure. BACKGROUND
[0002] The range hood is a household kitchen for sucking oil fume and the like generated during cooking. It not only has a good functional role, but also has a decorative concept that integrates the modern kitchen layout. After the development of the range hood, the range hood has not been limited to a simple tool for removing oil fume in the kitchen, but has increased more entertainment functions and use functions, such as an entertainment range hood with a television display, a range hood with a security system integrated with a smart home, a network range hood with network control, etc. The range hood needs to be cleaned regularly. Simple cleaning cannot remove oil stains. The range hood must be cleaned with professional cleaning agents. The most important part of the range hood is the motor that drives the fan. The bearing is an important part of the motor. When purchasing, attention should be paid to selecting a motor with double-ball bearings, which has a long service life and low noise. In addition, a full-metal plastic-injected fan should be selected, which is solid, durable, stable in performance, and conducive to oil fume separation. The smaller the noise after the motor starts and stops, the better.
[0003] For example, the patent document with the announcement number CN 107332375 B discloses a range hood motor, which includes a motor shell, a stator, a rotor, and a motor shaft. The two ends of the shell are provided with end covers. The rotor includes a rotor core and a plurality of magnetic steel sheets. The rotor core is provided with a plurality of magnetic steel sheet mounting through holes extending along the axial direction of the rotor. The magnetic steel sheets are one-to-one correspondingly arranged in the magnetic steel sheet mounting through holes. The two ends of the rotor core are provided with a plurality of insertion holes extending along the axial direction of the rotor and distributed in a circumferential direction. The motor shaft includes two half shafts. One end of each half shaft is supported on the end cover through a support bearing, and the other end of each half shaft is provided with a plurality of driving claws one-to-one correspondingly arranged in the insertion holes. The rotor and the half shafts are connected together and separated conveniently only through the driving claws to transmit torque. The present application has the advantages that the magnetic steel sheets are not easily hit, and the rotor and the motor shaft can be connected together without large pressure extrusion and separated conveniently.

The top of the protective cover 1 is movably connected to the connecting seat 36. The surface of the connecting seat 36 is fixedly connected to the exhaust pipe 37. The inner wall of the exhaust pipe 37 is provided with a noise reduction inner liner 38. The bottom of the connecting seat 36 is fixedly connected to the ventilation seat 39 on both sides. The ventilation seat 39 is provided with a plug-in groove 40. Normally, the connecting seat 36 can be plugged into the top of the protective cover 1, so that the plug-in groove 40 of the ventilation seat 39 at the bottom of the connecting seat 36 is adapted to the plug-in strip 34 inside the top of the protective cover 1. The ventilation seat 39 and the exhaust top groove 35 are adapted to each other. Then, by rotating the air control roller 31 up and down, and in conjunction with the partitioned air ducts on both sides inside the protective cover 1, the range hood and the single stove can be adapted and adjusted for operation, so as to complete the operation of the range hood more quietly.
[0022] The mounting assembly includes a pull-out plate 5, which is movably connected to the front of the protective cover 1. A pull-out seat 6 is fixedly connected to the bottom of the pull-out plate 5. A drive frame 7 is mounted on the top of the back of the pull-out plate 5. A motor body 8 is housed inside the drive frame 7. A fan body 9 is mounted on the bottom of the drive frame 7 via the motor body 8. Three partitioned inner liner 10s are evenly arranged on the back of the pull-out seat 6. The suction assembly includes a suction frame 11, which is fixedly connected to the bottom of the protective cover 1. A fan body 9 is fixedly connected to the back of the suction frame 11. The wall-mounted bracket 12 and the suction bracket 11 have side sloping covers 13 on both sides of their surfaces. The inner walls of the side sloping covers 13 have inclined sound-absorbing covers 14. The bottom of the suction bracket 11 is fixedly connected to a suction base cover 15. The inner wall of the suction base cover 15 has a suction sound-absorbing cover 16, and the inner bottom wall of the suction base cover 15 has a suction grille 17. A mounting base 18 is fixedly connected to the front of the suction bracket 11. A rotating shaft 19 is located at the bottom of the mounting base 18. A rotating bracket 20 is movably connected to the front of the mounting base 18 via the rotating shaft 19. A control panel 21 is located at the center of the front of the rotating frame 20. Fixing bolts 22 are located at both ends of the front of the rotating frame 20. Air collection hoods 23 are evenly distributed on the surface of the partitioned inner liner 10.

A top exhaust grille 27 is provided at the top of both the first and second insertion covers 25. Side exhaust grilles 28 are provided on both sides, and the pull plate 5 is connected to the pull seat 6 at the bottom, which allows the inner liner 10 to be pulled out from inside the suction frame 11. This pull-out design facilitates the cleaning and maintenance of the range hood at any time. In daily life, the rotating frame 20 is simply rotated along the rotating shaft 19 of the mounting base 18, and then the pull plate 5 and the pull seat 6 are locked and fixed by the fixing bolts 22 at both ends of the front of the rotating frame 20, ensuring the quiet operation inside at all times.
[0023] Working principle: In use, the user first assembles the motor body 8 and the impeller body 9 inside the drive frame 7, and then fixes the drive frame 7 as a whole to the center of the back of the pull plate 5. Next, the first insertion cover 25 and the second insertion cover 26 are connected and installed on both sides of the back of the pull plate 5, performing a fitting limiting cover connection operation on the drive frame 7. Afterwards, the drive frame 7 can be directly inserted into the protective cover 1 through the limiting insertion of the pull plate 5. At this time, the drive frame 7 at the center of the back of the pull plate 5 can be directly fitted and inserted into the inner motor cover 2 and the inner impeller cover 3 at the center of the protective cover 1. Daily operation is performed inside the inner motor cover 2 and the inner impeller cover 3. During operation, the inner motor cover 2 and the inner impeller cover 3... The inner wall's four inner soundproof covers allow for deep sound absorption and noise reduction. The first and second plug-in covers 25 and 26 are fitted into the gaps between the protective outer cover 1, the motor inner cover 2, and the impeller inner cover 3. Through the top and side exhaust grilles 27 and 28 of the first and second plug-in covers 25 and 26, a two-layer sound absorption and noise reduction operation is achieved for the motor body 8 and impeller body 9 inside the drive frame 7. Combined with the outermost protective outer cover 1, this achieves a three-layer efficient and quiet range hood motor installation. Simultaneously, the pull-out seat 6 connected to the bottom of the pull plate 5 allows for the movable extraction of the partitioned inner liner 10 within the suction frame 11. This pull-out design facilitates easy extraction of oil fumes. For internal cleaning and maintenance, the rotating frame 20 is simply rotated along the rotating shaft 19 of the mounting base 18, and then the pull plate 5 and pull seat 6 can be pulled out and locked by the fixing bolts 22 at both ends of the front of the rotating frame 20, ensuring a quiet internal operation at all times. During daily use, the range hood can be quickly wall-mounted using the wall-mounting bracket 12 inside the suction frame 11. The two sets of side slant covers 13 and the suction bottom cover 15 can be combined and installed on the sides and bottom of the suction frame 11 respectively. The vertical adjustment can be achieved by starting the drive motor 30 at the upper and lower center adjustment seat 29 between the protective outer cover 1, the motor inner cover 2, and the impeller inner cover 3. The air control roller 31 controls the airflow on both sides inside the protective cover 1, controlling the air intake at the side exhaust vent plates 32 on both sides of the protective cover 1. Combined with the side slanted covers 13 installed on both sides of the protective cover 1, this enables air intake within the suction frame 11. Inside the suction frame 11, the airflow is also enhanced by the air collection hood 23 and air inlet 24 within the three-section inner liner 10, allowing the range hood to operate in sections at the bottom of the suction frame 11, resulting in quieter smoke extraction. Furthermore, the bottom suction cover 15 at the bottom of the suction frame 11 is equipped with a noise reduction cover 16 and a suction grille 17, while the side slanted covers 13 are equipped with an internal slanted noise reduction cover 14.The side exhaust vent plate 32 can also be noise-reduced through the side soundproof cover 33, making the entire fume extraction duct a stable, quiet, and noise-reducing structure, greatly improving the quiet operation of the equipment. Simultaneously, the connecting seat 36 can be plugged into the top of the protective cover 1, with the insertion slot 40 of the ventilation seat 39 at the bottom of the connecting seat 36 fitting into the insertion strip 34 inside the top of the protective cover 1. The ventilation seat 39 and the exhaust top groove 35 are then matched and connected. By rotating the air control roller 31 up and down, in conjunction with the partitioned air ducts on both sides inside the protective cover 1, the range hood can be adjusted for operation with or without a single stove, resulting in quieter operation. The above describes the entire working principle of this invention.
[0024] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
