DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-3 The utility model provides a technical solution: a commercial kitchen noise-reducing and oil fume purification device, comprising a smoke hood 1, a conical frame 2 is fixed to the top of the smoke hood 1, two fixing rods 3 are fixed inside the conical frame 2 by bolts, a fan 4 is fixed between the opposite ends of the two fixing rods 3, a smoke exhaust pipe 5 is fixed to the top of the conical frame 2, a noise-reducing and purification component 200 for purifying and silencing oil fume is installed inside the smoke exhaust pipe 5, and an oil suction component 300 for sucking oil from the oil fume is installed inside the smoke hood 1;

[0024] Through the coordinated use of the smoke hood 1, the fan 4, the smoke exhaust pipe 5, the silencer and purification component 200 and the oil suction component 300, in actual use, while effectively eliminating oil smoke, it can also effectively avoid the commercial kitchen oil fume purification device from generating noise and causing secondary pollution during use, thereby avoiding the human body from being in an environment with excessive noise for a long time, causing noise disease, neurasthenia and other diseases, ensuring that there will be no physiological and psychological effects on the human body, and after a period of use, the structure used for silencer and purification can be conveniently and effectively removed from the device for cleaning and replacement, thereby improving the practicality of the commercial kitchen oil fume purification device.

[0025] In this embodiment, the silencing and purification component 200 is a structure for purifying and silencing oil smoke.

[0026] like Figure 1 、 Figure 2 and Figure 3 As shown, the silencer and purification assembly 200 includes a purification cylinder 201 fixed to the top of the fan 4 by bolts, an annular plate 202 is fixed to the inside of the purification cylinder 201 by bolts, two first silencer plates 203 are fixed to the inside of the annular plate 202, two second silencer plates 204 are fixed to the inside of the annular plate 202, an annular block 205 is fixed to the inside of the purification cylinder 201, and two fixed plates 206 are slidably connected to the inside of the purification cylinder 201, the bottom of the top fixed plate 206 is slidably connected to the second filter layer 208, and the top of the bottom fixed plate 206 is slidably connected to the first filter layer 207.

[0027] It should be noted that the purification cylinder 201 is slidably connected to the inside of the smoke exhaust pipe 5, and the outer diameter of the purification cylinder 201 is equal to the inner diameter of the smoke exhaust pipe 5, so that the purification cylinder 201 slides more stably in the smoke exhaust pipe 5, while also ensuring that the purification cylinder 201 can silence and purify all oil smoke entering the smoke exhaust pipe 5.

[0028] In addition, the first silencer plate 203 is located on the top of the second silencer plate 204. Both the first silencer plate 203 and the second silencer plate 204 are foam aluminum plates, and ventilation holes are provided on the tops of the first silencer plate 203 and the second silencer plate 204. The diameter of the ventilation holes on the top of the second silencer plate 204 is larger than the diameter of the ventilation holes on the top of the first silencer plate 203, ensuring that the coordinated use of the first silencer plate 203 and the second silencer plate 204 can effectively silence the oil smoke.

[0029] In addition, the first filter layer 207 is a scouring pad layer, and the second filter layer 208 is a cotton cloth layer. The first filter layer 207 and the second filter layer 208 are located between the opposite sides of the two fixed plates 205. The top of the top fixed plate 206 is in close contact with the bottom of the annular block 205. Bolts are threadedly connected between the insides of the two fixed plates 206, and the bolts are threadedly connected to the annular block 205, thereby realizing the fixing of the first filter layer 207 and the second filter layer 208 by the fixed plate 206 and the annular plate 205, and subsequent disassembly is also more convenient.

[0030] In this embodiment, the oil absorption assembly 300 is a structure for absorbing oil from cooking fumes.

[0031] like Figure 1As shown, the oil suction assembly 300 includes two sliders 301 respectively slidably connected to the left and right inner walls of the smoke hood 1, a first collection frame 302 is fixed to the top of the slider 301, a second collection frame 303 is fixed to the opposite side of the two sliders 301, an oil suction plate 304 is fixed to the opposite side of the two first collection frames 302, and a movable groove 305 is provided on the left and right inner walls of the smoke hood 1.

[0032] It should be noted that the slider 301 slides inside the movable groove 305, and the first collection frame 302 slides inside the movable groove 305, ensuring that when the oil absorption plate 304 needs to be cleaned, the slider 301 and the first collection frame 302 can be slid out of the smoke collection hood 1 from the movable groove 305. During use, the slider 301 is fixed to the smoke collection hood 1 by bolts to ensure the stability of the oil absorption plate 304 during use.

[0033] In addition, the top of the second collection frame 303 is fixed to the bottom of the oil absorption plate 304, so that the second collection frame 303 is installed more stably, and the opposite sides of the two oil absorption plates 304 are fixed to ensure that the oil absorption plates 304 can absorb all the oil smoke entering the smoke hood 1.

[0034] In addition, the width of the oil absorption plate 304 is equal to the width inside the smoke hood 1, ensuring that the oil absorption plate 304 can absorb the oil smoke entering the smoke hood 1. The outer diameter of the annular plate 202 is equal to the inner diameter of the purification cylinder 201, so that the annular plate 202 is more stably fixed in the purification cylinder 201 by bolts.

[0035] The working principle of the above embodiment is:

[0036] When in use, the fan 4 is turned on to suck the oil smoke generated in the kitchen into the smoke collecting hood 1, and the oil in the oil smoke is effectively absorbed by the oil absorption plate 304, and the oil absorption plate 304 is installed in an inclined manner. The oil attached to the oil absorption plate 304 will flow downward along the oil absorption plate 304, and then flow into the first collection frame 302 and the second collection frame 303 respectively. Then, the smoke after the oil absorption treatment will enter the purification cylinder 201, and through the cooperation of the first filter layer 207 and the second filter layer 208, the purpose of removing the oil smoke is achieved. Then, through the cooperation of the first silencer 203 and the second silencer 204, the noise generated during the emission of the oil smoke can be effectively reduced. The oil absorption is carried out to avoid the noise affecting people's normal life. After a period of use, the slider 301 is made to slide in the movable groove 305, and the oil absorption plate 304 can be taken out from the smoke hood 1 for cleaning, and the oil in the first collection frame 302 and the second collection frame 303 can be cleaned. Then, by loosening the bolts, the fan 4 can be removed from the conical frame 2, so that the purification cylinder 201 can be taken out from the exhaust pipe 5, and the first silencer plate 203, the second silencer plate 204, the first filter layer 207 and the second filter layer 208 can be taken out for cleaning or replacement, thereby ensuring that the device can achieve the expected silencer and purification effect in the future.

[0037] Compared with the existing technology, the commercial kitchen noise-absorbing and fume purification device, through the coordinated use of the fume hood 1, the fan 4, the exhaust pipe 5, the noise-absorbing and purification component 200 and the oil absorption component 300, can effectively eliminate the fume during actual use while effectively avoiding the secondary pollution caused by the noise generated by the commercial kitchen fume purification device during use, thereby avoiding the human body from being in an environment with excessive noise for a long time, causing noise diseases, neurasthenia and the like, ensuring that there will be no physiological and psychological effects on the human body. Moreover, after a period of use, the structure used for noise reduction and purification can be conveniently and effectively removed from the device for cleaning and replacement, thereby improving the practicality of the commercial kitchen noise-absorbing and fume purification device and solving the problem of low practicality of the existing commercial kitchen fume purification device.
