Description

Technical Field

[0001] This utility model belongs to the field of range hood technology, and specifically relates to a range hood. Background Technology

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. It is installed above the stove in a healthy and energy-saving kitchen and can quickly remove the waste from the stove and the harmful fumes produced during cooking, exhausting them outdoors, reducing pollution, purifying the air, and providing safety protection against poisoning and explosion.

[0003] As people's living standards continue to improve, range hoods are gradually becoming a part of people's lives. Range hoods require mounting brackets during installation. The current installation method involves using expansion screws to fix the mounting bracket to the wall. The mounting bracket has two hooks for fixed connection, and two corresponding hanging holes are made on the back of the range hood casing. After fixing the mounting bracket, the range hood needs to be lifted up, and the two hanging holes are connected to the two hooks. Because range hoods are generally heavy, a certain degree of precision is required during connection, making the operation quite difficult.

[0004] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Utility Model Content

[0005] The purpose of this utility model is to provide a range hood that can be quickly hung on the hook of the mounting bracket, reducing the difficulty of operation.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A range hood includes a range hood body and a mounting assembly. The mounting assembly includes a fixing plate fixedly connected to a wall and a mounting mechanism mounted on the fixing plate. The mounting mechanism includes a mounting plate connected to the fixing plate and two hooks slidably mounted on the mounting plate. The back of the range hood body has a hanging groove that mates with the hooks. The mounting plate has a sliding groove for the hooks to slide, the length of which is equal to the length of the hanging groove. A pull rope is connected to the side of the hook near the end of the sliding groove, and a through hole is formed on the side of the mounting plate for the pull rope to pass through.

[0008] Further specifying, the hook includes a sliding plate slidably connected to the slide groove, a support plate located outside the mounting plate, and a connecting plate connecting the sliding plate and the support plate. The connecting plate is located above the slide groove, and the bottom of the support plate forms an upwardly bent hanging plate that passes through the hanging groove. A locking element is also provided on the side of the connecting plate near the end of the slide groove. This structural design enhances the load-bearing capacity of the hook and improves installation safety.

[0009] Furthermore, the bottom of the slide plate forms a limiting slider, and the bottom of the slide groove forms a limiting cavity that mates with the limiting slider. The pull rope is fixedly connected to the limiting slider. This structural design, through the limiting slider and the limiting cavity, enhances the connection strength between the hook and the mounting plate.

[0010] Furthermore, the top of the mounting plate is provided with a mounting groove parallel to the sliding groove, and a plurality of first pulleys are arranged in the mounting groove along its length, with the connecting plate in rolling contact with the first pulleys. This structural design reduces friction between the hook and the mounting plate through the first pulleys, making it easier to pull the hook.

[0011] Furthermore, a plurality of second pulleys are provided between the hanging plate and the supporting plate, and the inner top wall of the hanging groove makes rolling contact with the second pulleys. This structural design reduces friction between the hook and the hanging groove through the second pulleys, making it easier to pull the hook.

[0012] Further specifying, the locking component includes an elastic strip fixedly connected to one side of the connecting plate and a limiting block located at the bottom end of the elastic strip, the bottom surface of the limiting block being an arc-shaped surface; the end face of the slide groove forms a groove for the locking component to enter, the front end of the groove forms a guide surface, and the rear end forms a locking slot that mates with the limiting block. This structural design allows the limiting block to easily engage with the locking slot via the elastic strip.

[0013] Furthermore, the mounting plate is slidably mounted on the fixed plate, and the fixed plate is also provided with an adjustment mechanism for adjusting the height of the mounting plate; a limiting groove is formed on the fixed plate, and a limiting slide block is formed on the mounting plate that slidably engages with the limiting groove. This structural design allows for appropriate adjustment of the mounting plate's height during installation by sliding the mounting plate onto the fixed plate.

[0014] Further specifying, the adjustment mechanism includes a screw rotatably mounted on the fixed plate, a drive seat formed on the mounting plate that threadedly engages with the screw, and a sliding cavity formed on the fixed plate that slidably engages with the drive seat. The screw is rotatably mounted within the sliding cavity. This structural design simplifies operation by adjusting the height of the mounting plate via the screw.

[0015] Furthermore, the back of the range hood body is also equipped with a shock-absorbing pad. This structural design, using the shock-absorbing pad, can reduce the vibration between the range hood and the wall during use.

[0016] Furthermore, the range hood body also includes a gesture control module; the gesture control module includes an infrared transmitter that generates infrared signals and an infrared receiver that receives infrared signals. This structural design allows for easier control of the range hood's start and stop via the gesture control module.

[0017] The utility model employing the above technical solution has the following advantages:

[0018] 1. This utility model involves sliding two hooks onto a mounting plate and creating only one hanging groove on the range hood body, the same length as the sliding groove. Before hanging the range hood, the two hooks are brought together and pressed against each other. Then, the range hood body is lifted so that the hanging groove is hooked onto the two hooks. The range hood is then secured by pulling the two hooks to the sides with a pull rope. Since the two hooks are pressed against each other and there is only one hanging groove, it is not necessary to match each hook with the hanging groove when hanging the range hood body, greatly reducing the difficulty of installation.

[0019] 2. This utility model, through the first pulley and the second pulley, can reduce the friction between the hook and the mounting plate and the hanging groove, making it easier to pull the hook to both sides.

[0020] 3. This utility model allows for easy and quick adjustment of the mounting plate height via a screw, eliminating the need for precise measurement and positioning of the mounting plate during installation, thus enabling rapid installation and increasing the tolerance for errors.

[0021] 4. This utility model utilizes shock-absorbing pads to reduce vibration between the range hood and the wall during use. Attached Figure Description

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0049] In the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating the connection relationship between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0050] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model relates to a range hood, which includes a range hood body 1 and an installation assembly. The installation assembly includes a fixing plate 2 that can be fixedly connected to the wall by expansion bolts, and an installation mechanism 3 mounted on the fixing plate 2. The installation mechanism 3 includes an installation plate 31 connected to the fixing plate 2 and two hooks 32 that are slidably mounted on the installation plate 31. The back of the range hood body 1 has a hanging groove 11 that cooperates with the hooks 32. The installation plate 31 has a sliding groove 311 for the hooks 32 to slide, and the length of the sliding groove 311 is equal to the length of the hanging groove 11. A pull rope 321 is connected to the side of the hooks 32 near the end of the sliding groove 311, and a through hole is formed on the side of the installation plate 31 for the pull rope 321 to pass through. In addition, the fixing plate 2, the installation plate 31 and the hooks 32 are all made of metal materials. The fixing plate 2 and the hooks 32 are made of stainless steel to ensure high strength and high load-bearing capacity, while the installation plate 31 is made of lightweight and high-strength aluminum alloy to reduce weight while ensuring performance.

[0051] By sliding two hooks 32 onto the mounting plate 31, and starting only one hanging groove 11 of the same length as the sliding groove 311 on the range hood body 1, before hanging the range hood, the two hooks 32 are brought together and attached to the center, and then the range hood body 1 is lifted so that the hanging groove 11 is attached to the two hooks 32. Then, the range hood is fixed by pulling the two hooks 32 to the sides with the pull rope 321. Since the two hooks 32 are attached and there is only one hanging groove 11, it is not necessary to match each hook 32 with the hanging groove 11 when hanging the range hood body 1, which greatly reduces the difficulty of installation.

[0052] Specifically, the pull rope 321 is a steel wire rope or nylon rope, with a pull ring at the end. After fixing the fixing plate 2 to the wall with expansion bolts, the two hooks 32 are brought together and pressed tightly. After hooking the hooks 32 into the hanging groove 11, the two hooks 32 are pulled to both sides by the pull rope 321 until they are in contact with both ends of the sliding groove 311. Using this structure for installation, both hooks 32 can be quickly hooked into the hanging groove 11 at the same time, greatly reducing the difficulty of installation and improving the efficiency of installation.

[0053] like Figures 9 to 11As shown, the hook 32 includes a sliding plate 322 slidably connected to the slide groove 311, a support plate 323 located outside the mounting plate 31, and a connecting plate 324 connecting the sliding plate 322 and the support plate 323. The connecting plate 324 is located above the slide groove 311. The bottom of the support plate 323 forms an upwardly bent hanging plate 325, which passes through the hanging groove 11. The bottom of the sliding plate 322 forms a limiting slider 3221, and the bottom of the slide groove 311 forms a limiting cavity 3111 that cooperates with the limiting slider 3221. The pull rope 321 is fixedly connected to the limiting slider 3221. This structure can enhance the load-bearing capacity of the hook 32, prevent the hook 32 from detaching from the mounting plate 31, enhance the connection strength between the hook 32 and the mounting plate 31, and improve the safety of installation. Additionally, a locking member 326 is provided on one side of the connecting plate 324 near the end of the slide groove 311. The locking member 326 includes an elastic strip 3261 fixedly connected to one side of the connecting plate 324 and a limiting block 3262 located at the bottom of the end of the elastic strip 3261. The bottom surface of the limiting block 3262 is an arc-shaped surface. The end face of the slide groove 311 forms a groove 316 for the locking member 326 to enter. The front end of the groove 316 forms a guide surface 3161, and the rear end forms a slot 3162 that cooperates with the limiting block 3262. The elastic strip 3261 can be made of stainless steel, and the limiting block 3262 can be made of plastic. When the hook 32 is pulled to both sides, the limiting block 3262 can tilt upwards through its cooperation with the guide surface 3161, enter the slot 316, and then enter the bayonet 3162. The hook 32 is limited by the cooperation between the bayonet 3162 and the limiting block 3262, so as to prevent the hook 32 from moving during the use of the range hood.

[0054] like Figure 7 , Figure 8 As shown, the top of the mounting plate 31 is also provided with a mounting groove 312 parallel to the sliding groove 311. Several first pulleys 313 are arranged along the length of the mounting groove 312, with equal spacing between them. The first pulleys 313 are rotatably connected to the mounting groove 312, and the bottom of the connecting plate 324 makes rolling contact with the first pulleys 313. When the hook 32 is pulled, the bottom plate and the first pulleys 313 are in rolling contact, greatly reducing friction and making the operation easier and less strenuous.

[0055] like Figure 11 As shown, a plurality of second pulleys 327 are provided between the hanging plate 325 and the supporting plate 323. The plurality of second pulleys 327 are installed at equal intervals along their moving direction, and the inner top wall of the hanging groove 11 makes rolling contact with the second pulleys 327. The second pulleys 327 can reduce the friction between the hook 32 and the hanging groove 11, making it easier and less strenuous to pull the hook 32.

[0056] like Figure 5 , Figure 6As shown, the mounting plate 31 is slidably mounted on the fixed plate 2. The fixed plate 2 is also provided with an adjustment mechanism for adjusting the height of the mounting plate 31. A limiting groove 21 is formed on the fixed plate 2, and a limiting slide 314 that slides with the limiting groove 21 is formed on the mounting plate 31. The adjustment mechanism includes a screw 4 rotatably mounted on the fixed plate 2. A drive seat 315 that is threadedly engaged with the screw 4 is formed on the mounting plate 31. A threaded hole that engages with the screw 4 is formed on the drive seat 315. A sliding cavity 22 that slides with the drive seat 315 is formed on the fixed plate 2. The screw 4 is rotatably mounted in the sliding cavity 22. There are two limiting grooves 21, and the sliding cavity 22 is located between the two limiting grooves 21.

[0057] Specifically, the limiting groove 21 is a T-shaped groove, and the top of the screw 4 has an internal hexagonal countersunk hole. When adjusting the height of the mounting plate 31, a ratchet wrench can be used to turn the screw 4 to adjust the height of the mounting plate 31. In addition, it should be noted that the height adjustment is done before the range hood body 1 is hung on the hook 32.

[0058] like Figure 2 As shown, a shock-absorbing pad 12 is also provided on the back of the range hood body 1. The shock-absorbing pad 12 can reduce the vibration between the range hood and the wall during use.

[0059] like Figure 3 , Figure 4 As shown, a gesture control module is also installed inside the range hood body 1; the gesture control module includes an infrared transmitter 5 that can generate infrared signals and an infrared receiver 6 that receives infrared signals. The center line of the infrared transmitter 5 makes an angle of 10° with the horizontal plane; the infrared transmitter 5 emits infrared signals, and if the infrared signals are blocked by a hand, they will be reflected back to the infrared receiver 6, realizing the range hood functions such as opening, closing, and adjusting the speed by gesture.

[0060] The method of using this utility model is as follows:

[0061] First, after fixing the mounting plate 2 to the wall with expansion bolts, adjust the mounting plate 31 to a suitable height using screw 4. Then, bring the two hooks 32 close together. Next, the worker can lift the range hood body 1 so that the two hooks 32 can be hooked into the hanging groove 11 at the same time. Finally, pull the two hooks 32 to both sides using the pull rope 321 until the locking piece 326 is engaged in the locking groove 316 to limit and fix the hooks 32. The pull rope 321 can also be fixed to the hooks on both sides of the mounting plate 2.
