Description

Technical Field

[0001] The utility model relates to the technical field of smoke hoods, in particular to a variable frequency smoke hood with a flap structure. Background Art

[0002] The variable frequency fume hood is an intelligent and energy-saving kitchen equipment, which is mainly used to collect, filter and discharge the fume and odor generated in the kitchen. It adopts the variable frequency technology, which can automatically adjust the fan speed according to the actual situation of the kitchen, so as to achieve the effect of energy saving. At the same time, the variable frequency fume hood is also equipped with an efficient filtering system, which can effectively filter out the fume and odor, and ensure the freshness and hygiene of the kitchen air.

[0003] In the prior art, for example, a Chinese patent with publication number CN216384321U discloses a range hood with a flap at the bottom, which includes a range hood body and a fume collecting hood fixed at the bottom of the range hood body, wherein an air inlet is arranged at the bottom of the fume collecting hood; a flap is arranged at the air inlet, and two connecting rod assemblies are arranged inside the fume collecting hood, and the two connecting rod assemblies are respectively hinged to the two ends of the flap in the length direction; through the rotation of the connecting rod assembly, the flap has a closed state and an open state; when the flap is in the closed state, the flap covers the air inlet; when the flap is in the open state, the flap opens the air inlet. The flap of the utility model can cover the air inlet when the range hood is not working, thereby reducing the pollution of impurities such as dust to the range hood.

[0004] However, the above patent has some shortcomings. In actual use, in order to obtain a larger smoke cage cavity and improve the smoke absorption effect of the range hood, the patent uses an air guide plate with a large flap structure. However, the area of ​​this type of air guide plate structure is roughly equal to the overall area of ​​the smoke inlet surface of the smoke hood. When this type of air guide plate structure is in a closed state, it can completely cover the smoke inlet surface of the smoke hood, and the appearance is neat and generous. However, in the open state, the large size of the flap will generally affect the cook's line of sight. Even when the installation space is small, the air guide plate will interfere with cooking during the opening or closing process, seriously reducing the cook's experience. Therefore, a variable frequency hood with a flap structure is proposed to solve the above problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model proposes a variable frequency smoke hood with a flap structure. By setting the flap structure in a flat opening manner, the size of the air inlet can be adjusted at will, which has better adaptability and can avoid the problem of cooking restrictions due to the opening of the flap.

[0006] The technical solution to achieve the purpose of the utility model is: a variable frequency smoke hood with a flap structure, including a body, a plurality of fixed blocks are fixedly connected to the lower surface of the body, the opposite surfaces of the plurality of fixed blocks are fixedly connected to slide rails, the inner walls of the two slide rails are slidably connected to two pulleys, the opposite surfaces of the plurality of pulleys are fixedly connected to the same fixed frame, a flap body is arranged on the fixed frame, the lower surface of the fixed frame is fixedly connected to a rack, the lower surfaces of the two slide rails are fixedly connected to mounting blocks, the opposite surfaces of the two mounting blocks are rotatably connected to the same rotating rod, a gear is sleeved and installed on the surface of the rotating rod, the gear is meshed with the rack, and one end of the rotating rod is fixedly connected to a turning handle.

[0007] In some embodiments, the two sides of the body are fixedly connected with a same protective cover, and the handle is arranged outside the protective cover.

[0008] In some embodiments, a frequency conversion module is provided on the machine body, and an oil collecting box is detachably connected to the inner wall of the machine body.

[0009] In some embodiments, a plurality of first fixing rods are fixedly connected to the inner wall of the fixing frame, and surfaces of the plurality of first fixing rods are rotatably connected to rotating rods.

[0010] In some embodiments, a plurality of connecting plates are fixedly connected to the lower surface of the flap body, a second fixing rod is fixedly connected to one side of each of the connecting plates, and an end of each of the rotating rods away from the first fixing rod is respectively rotatably connected to the surface of the corresponding plurality of second fixing rods.

[0011] In some embodiments, a limiting plate is fixedly connected to the lower surface of the body, a limiting slot is penetrated through one side of the limiting plate, and a roller is rotatably connected to the surface of one of the second fixing rods, and the roller is adapted to the limiting slot and is slidably connected.

[0012] Compared with the prior art, the present invention has the following significant advantages:

[0013] The utility model drives the rotation of the rotating rod by rotating the turning handle, and then drives the rotation of the gear. The rack can be driven by the rotation of the gear, thereby driving the fixed frame to slide on the slide rail through the pulley. The movement of the fixed frame can make the flap body move synchronously through the connection of the first fixed rod, the second fixed rod and the rotating rod. When the rotating rod rotates, the roller will be stuck in the limiting groove and slide inside, thereby achieving limitation in the movement process and improving the stability of the movement. The problem of inconvenient installation due to excessive size can be solved by opening and closing horizontally.

[0014] The invention solves the problem that when the flap is opened, the flap is too large, which affects the cook's sight. Even when the installation space is small, the air guide plate may interfere with cooking during the opening or closing process, which seriously reduces the cook's experience.

[0024] The utility model provides a variable frequency smoke hood with a flap structure through improvement. The technical solution of the utility model is:

[0025] like Figure 1As shown, the variable frequency smoke hood with a flap structure includes a body 1, a plurality of fixed blocks 4 are fixedly connected to the lower surface of the body 1, and the opposite surfaces of the plurality of fixed blocks 4 are fixedly connected to slide rails 5, and the inner walls of the two slide rails 5 are slidably connected to two pulleys 6, and the pulleys 6 and the inner parts of the slide rails 5 are adapted to provide support for the movement of the fixed frame 7, and the opposite surfaces of the plurality of pulleys 6 are fixedly connected to the same fixed frame 7, and the fixed frame 7 is composed of four rectangular square tubes, and a flap body 16 is arranged on the fixed frame 7, and a rack 12 is fixedly connected to the lower surface of the fixed frame 7, and the lower surfaces of the two slide rails 5 are fixedly connected to mounting blocks 8, and the opposite surfaces of the two mounting blocks 8 are rotatably connected to the same rotating rod 9, and a gear 11 is sleeved and installed on the surface of the rotating rod 9, and the gear 11 is meshed with the rack 12, and one end of the rotating rod 9 is fixedly connected to a turning handle 10, and the turning handle 10 is extended to the outside of the protective cover 3 through the rotating rod 9 for installation, so as to facilitate the adjustment of the opening and closing work.

[0026] like Figure 1 and 2 As shown, in one embodiment, the same protective cover 3 is fixedly connected to both sides of the body 1. The protective cover 3 can prevent the internal components from being affected by oil stains. The protective cover 3 is made of a smooth mirror material, which saves effort when cleaning the oil stains. The handle 10 is arranged on the outside of the protective cover 3.

[0027] The machine body 1 is provided with a frequency conversion module 2 , and the inner wall of the machine body 1 is detachably connected with an oil collecting box 13 , which can be arranged to be connected to the inside of the machine body 1 in a plug-in manner.
