Description

Technical Field

[0001] The utility model relates to a range hood, in particular to a Chinese-style range hood, and belongs to the technical field of range hoods. Background Art

[0002] Chinese-style range hoods are simple, lightweight and economical. European-style range hoods are more luxurious in appearance, but the price is slightly higher. Families with smaller kitchens mainly choose "Chinese-style" range hoods, which pay more attention to cost-effectiveness and practicality. The price of Chinese-style range hoods on the market is only about one-third of that of European-style range hoods. After years of development, the technology of "Chinese-style" range hoods is quite mature. The depth of the smoke collection chamber is 2.5 times that of ordinary European-style range hoods, which is more conducive to collecting rising oil smoke and has a more ideal smoke exhaust effect. In addition, the motor fan of the Chinese-style range hood is vertically facing the oil smoke sucked in, which can quickly exhaust the oil smoke. There will be no oil smoke stagnation and overflow in the smoke collection chamber, so grease will not remain in the smoke collection chamber.

[0025] The embodiment of the utility model provides a Chinese-style range hood.

[0026] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The Chinese-style range hood comprises a range hood body 1, on which a first guide mechanism and a second guide mechanism 3 for limiting the diffusion of smoke are installed. The first guide mechanism comprises an air curtain machine 2 fixed at the front end of the range hood body 1. The air curtain machine 2 is started to blow air vertically downward to form an air curtain, and the front end of the range hood body 1 is blocked by the air curtain to block the smoke.

[0027] Please refer again Figure 1 and Figure 2 The second air guide mechanism 3 includes two side baffles 31 and a rear baffle 32. The rear baffle 32 is fixedly connected between the two side baffles 31. The two side baffles 31 slide at the two ends of the range hood body 1 respectively. The wind curtain formed by the air curtain machine 2 and the cooperation with the side baffles 31 and the rear baffle 32 form a shield around the bottom of the range hood body 1 to gather the smoke and prevent the smoke from diffusing outward, thereby increasing the suction force on the smoke under the range hood body 1. A connecting slide 4 is fixedly connected to the side baffle 31. Slide grooves adapted to the connecting slide 4 are provided at both ends of the range hood body 1. The connecting slide 4 slides inside the slide groove. The stability of the lifting process of the second air guide mechanism 3 is increased by setting the connecting slide 4 and the slide groove.

[0028] Please refer again Figure 1 , Figure 3 and Figure 4 A limiting mechanism for limiting the side baffle 31 from sliding downward is provided at the top of the range hood body 1. The limiting mechanism includes a fixed seat 5 fixedly connected to the range hood body 1, one end of the fixed seat 5 is slidably connected to a movable plug plate 51, and a rectangular frame 6 is fixedly connected to the top of the second air guide mechanism 3. One end of the movable plug plate 51 is plugged into the inside of the rectangular frame 6. By inserting one end of the movable plug plate 51 into the inside of the rectangular frame 6, the side baffle 31 is limited from sliding on the side of the range hood body 1. A plurality of rectangular slots 7 are provided on the side surfaces of the two side baffles 31 that are close to each other. Each group of rectangular slots 7 is partially on the side baffle 31 in a linear array. By inserting one end of the movable plug plate 51 into the rectangular slot 7 or the inside of the rectangular frame 6, the sliding of the second air guide mechanism 3 is limited. The distance value between the bottom of the second air guide mechanism 3 and the stove can be adjusted according to on-site installation requirements or usage conditions through the provision of the plurality of rectangular slots 7.

[0029] Please refer again Figure 1 , Figure 3 and Figure 4A sliding groove is provided inside the fixed seat 5, and one end of the movable plug plate 51 slides inside the sliding groove. One end of the movable plug plate 51 is fixedly connected to a connecting rod 52, and the other end of the connecting rod 52 extends to a side of the fixed seat 5, and the other end of the connecting rod 52 is fixedly connected to a connecting plate 53. A spring 54 is installed inside the sliding groove, and the spring 54 is sleeved on the connecting rod 52. By pulling the connecting plate 53 away from the fixed seat 5, one end of the movable plug plate 51 is pulled out from the inside of the rectangular frame 6 or the rectangular slot 7 under the connection action of the connecting rod 52, so that the side baffle 31 can slide freely on the two sides of the range hood body 1. By removing the side baffle 31 and the rear baffle 32 from the range hood body 1, it is convenient to clean and maintain the second guide mechanism 3. Under the action of the spring 54, the movable plug plate 51 can quickly slide and reset when it is not subjected to force.

[0030] Please refer again Figure 1 , Figure 3 and Figure 4 The top of the range hood body 1 is rotatably connected with a rotating rod 8, one end of the rotating rod 8 is fixedly connected with a connecting rope 81, and the other end of the connecting rope 81 is fixedly connected to the connecting plate 53. By driving the rotating rod 8 to rotate around the rotating shaft at one end of the rotating rod 8, the connecting rope 81 pulls the connecting plate 53 away from the fixed seat 5 to slide at the other end of the rotating rod 8. The range hood body 1 is provided with an air curtain machine 2. One end of the control panel 11 is fixedly connected to the control panel 11. The control panel 11 is provided to facilitate the operation and control of the device. One end of the movable plug plate 51 is in an arc shape. The arc-shaped movable plug plate 51 can squeeze the arc end of the movable plug plate 51 when the side baffle 31 rises, so that the other end of the movable plug plate 51 is retracted into the sliding groove. When the movable plug plate 51 passes through the next rectangular slot 7, the spring 54 rebounds and quickly slides back to limit the downward sliding of the second air guide mechanism 3.

[0031] Working principle: The device is installed at a suitable location and connected to the municipal power supply. The air curtain machine 2 is started to blow air vertically downward to form an air curtain. The formed air curtain cooperates with the side baffle 31 and the rear baffle 32 to form a protection around the bottom of the range hood body 1 to prevent the oil smoke generated by cooking from spreading outward, so that the smoke gathers at the bottom of the range hood body 1. The fan inside the range hood body 1 is started to absorb the smoke, thereby increasing the suction force on the smoke below the range hood body 1. The movable plug 51 is inserted at one end to form a protective film. The side baffle 31 is inserted into the rectangular frame 6 to limit the downward sliding of the side baffle 31. By driving the rotating rod 8 to rotate around the rotating axis at one end of the rotating rod 8, the connecting rope 81 pulls the connecting plate 53 away from the fixed seat 5 at the other end of the rotating rod 8 to slide, so that one end of the movable plug plate 51 is pulled out from the inside of the rectangular frame 6 or the inside of the rectangular slot 7, and the side baffle 31 is free to slide at both ends of the range hood body 1, so that it is convenient to adjust the depth value of the smoke gathered at the bottom of the range hood body 1 according to the on-site installation requirements, and the adaptability is good.
