Description

Mounting structure of range hood

Technical Field

The invention relates to an oil fume purification device, in particular to an installation structure of a range hood.

Background

The range hood works by utilizing the fluid dynamics principle, sucks and exhausts oil smoke through a centrifugal fan arranged in the range hood, and filters partial grease particles by using a filter screen. The centrifugal fan comprises a volute, an impeller arranged in the volute and a motor driving the impeller to rotate. When the impeller rotates, negative pressure suction is generated in the center of the fan, oil smoke below the range hood is sucked into the fan, accelerated by the fan and then collected and guided by the volute to be discharged out of a room.

At present, most of the extractor hood on-hook structures on the market adopt a traditional mode, namely, a hook is arranged on a wall body, and an on-hook hole is designed on the whole extractor hood, so that the extractor hood can be stably hung on the wall body. The utility model discloses a novel range hood's mounting structure as chinese patent application No. 201120248712.7, including locating the wind channel back plate on the range hood wind channel, the hanger plate with locate the link plate on the wall, way back plate and hanger plate fixed connection, the hanger plate is located the link plate, through having guide structure and heavy platform's wind channel back plate and locating the link plate that the wall just has certain inclination couple, when installing range hood, the couple on the link plate can make the link plate hang the hanger plate with wind channel back plate fixed connection under the effect of guide structure on the inclination of self and the wind channel back plate, thereby make the accurate installation of range hood target in place. The device is convenient to install, and the installation efficiency of the range hood can be greatly improved.

This kind of mode often can not satisfy user's individualized demand, mainly embodies and installs the wall cabinet at part user's home range hood, and because the problem of installation stroke (need raise the lampblack absorber earlier to the highest position value of couple during the installation, the complete machine can move down a section distance after hanging well), can have great installation gap with the wall cabinet after the complete machine installation, and the installation accuracy is poor, still can influence the whole outward appearance of range hood.

Furthermore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Referring to fig. 1 to 3, an installation structure of a range hood includes a hook assembly 1 disposed on a rear side of the range hood 100 and a hook assembly 2 for connecting with an external installation base, such as a wall, and through cooperation of the hook assembly 1 and the hook assembly 2, seamless installation of the range hood 100 and a wall cabinet can be achieved.

The hook component 1 comprises a first limiting hook 11 and a second limiting hook 12 which are arranged at an interval up and down, and the first limiting hook 11 is positioned above the second limiting hook 12. The first limit hook 11 is in the shape of an upward extending hook, the second limit hook 12 is in the shape of a downward extending hook, and both limit hooks protrude backwards from the rear side of the range hood 100 so as to be connected with the hook assembly 2.

The hook assembly 2 comprises a hook body 21, a first latch axis pin 22, a second latch axis pin 23 and a support swing arm 24. The first hook shaft pin 22 and the second hook shaft pin 23 are arranged at an interval up and down on one side of the hook body 21 facing the range hood 100 (hook assembly 1), and preferably, the two hook shaft pins are parallel. The first hook shaft pin 22 extends transversely in the left-right direction, and both ends of the first hook shaft pin are respectively connected with the hook body 21 through the first support frame 25 in a rotating manner (the first support frame 25 is fixed with the hook body 21, and the first hook shaft pin 22 is connected with the first support frame 25 in a rotating manner), or can be fixedly connected. The second hook shaft pin 23 extends transversely in the left-right direction, and both ends of the second hook shaft pin 23 are respectively rotatably connected with the hook body 21 through the second support frame 26 (the second support frame 26 is fixed with the hook body 21, and the second hook shaft pin 23 is rotatably connected with the second support frame 26), or can be fixedly connected.

The support swing arm 24 includes a swing arm body 241, a support groove 242 formed on the top surface of the swing arm body 241, and a slide groove 243 formed in the swing arm body 241. The support groove 242 is formed by the top surface of the swing arm body 241 being depressed downward, the front side of the support groove 242 gradually extends downward from the front to the rear, and the front side surface of the support groove 242 may be an inclined surface or a curved surface. The sliding grooves 243 extend in the left-right direction and penetrate the left and right sides of the swing arm body 241. The second hooking shaft pin 23 passes through the sliding groove 243 so that the supporting swing arm 24 is rotatably disposed on the second hooking shaft pin 23. The longitudinal length of the sliding slot 243 is greater than the longitudinal length of the second latching shaft pin 23, so that the supporting swing arm 24 can slide up and down relative to the second latching shaft pin 23. A limiting column 211 extending towards the extractor hood 100 (forwards) is arranged at the position of the hook body 21 below the supporting swing arm 24.

In the present embodiment, the sliding groove 243 has a kidney-shaped longitudinal section. Due to the adoption of the structure of the hook assembly 2, the longitudinal length of the sliding groove 243 is only about 3mm approximately, and the locking anti-falling function is realized, so that compared with the hanging groove (about 10mm in length) in the prior art, the length is greatly reduced, the sinking distance of the range hood 100 is greatly reduced, and the seamless installation with a hanging cabinet can be met.

Before the range hood 100 is installed, the support swing arm 24 in the hook assembly 2 is pulled out upwards and rotated forwards, so that the bottom end of the support swing arm 24 is placed on the limiting column 211 of the hook body 2, as shown in fig. 4 to 6; then, the range hood 100 is installed, the first limit hook 11 on the range hood 100 is inserted upwards between the first hook shaft pin 22 and the hook body 21 of the hook assembly 2, so that the first hook shaft pin 22 is supported on the first limit hook 11, thereby preventing the range hood 100 from tilting forwards; the second limit hook 12 on the range hood 100 is placed downwards at the front side of the support groove 242 of the support swing arm 24, the range hood 100 is continuously pushed backwards, the support swing arm 24 is pushed downwards, meanwhile, the support swing arm 24 rotates around the second hook shaft pin 23, so that the bottom end rotates forwards, until the bottom end of the support swing arm 24 rotates forwards out of the limit column 211 and slides off the limit column 211, the back side of the bottom end of the support swing arm 24 abuts against the limit column 211, the back side of the top end of the support swing arm 24 abuts against the hook body 21, and the rotation of the support swing arm 24 is avoided, so that the support swing arm 24 supports the whole weight of the range hood 100, and at this time, the range hood 100 can be fixed on an external installation base by means of self gravity, see.

When the range hood 100 needs to be disassembled, the range hood 100 is lifted upwards for a short distance, then the support swing arm 24 is pushed upwards to the limit column 211 of the hook body 21, and the range hood 100 is pulled outwards to disassemble the range hood 100.

The mounting structure of the invention has simple and stable structure, convenient mounting, safety and reliability, effectively reduces the clearance between the range hood and the hanging cabinet after mounting, can be used repeatedly and has good economical efficiency.
