Description

Technical Field

[0001] The invention relates to a wet-type smoke exhaust purification device for a kitchen, belonging to the technical field of range hoods. Background Art

[0002] The simplest existing range hoods use centrifugal fans to extract the oil smoke and discharge it to the outside. As the oil smoke cools, oil droplets form and adhere to the air, and there are oil stains in the air passages inside the machine, and there are also oil stains on the air outlet and flue. These oil stains not only pollute the environment, but also cause fire alarms, which has defects.

[0003] In addition, existing advanced oil fume cleaning equipment, such as the Chinese invention patent "Authorization Announcement No.: CN103394253B; Authorization Announcement Date: April 8, 2015; Name: An Oil Fume Cleaning Device", uses a layer of water curtain and a layer of filter plate to achieve two-stage impurity removal of oil fume, and is combined with an electrode dust removal device to effectively achieve oil and gas separation and smoke removal. However, its air intake channel can only use two water coolings for oil and gas separation, and does not have the function of automatically cleaning the inside of the device. There are defects such as incomplete oil and gas separation and inability to achieve self-cleaning. Summary of the Invention

[0004] The purpose of the present invention is to address the above-mentioned defects of the prior art and provide a kitchen wet fume exhaust purification device. The kitchen wet fume exhaust purification device optimizes the design of the air intake channel of the fume suction structure. The air intake channel is arranged obliquely as a whole, and has up to four layers of water curtain filtration inside. Combined with the electrostatic field purification device, it can more thoroughly extract and purify kitchen fumes.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A kitchen wet fume exhaust purification device includes a box body, a fume suction structure is provided in the middle of the lower front side of the box body, and a horizontal water trough arranged in the left and right directions is provided directly below the inlet of the fume suction structure. The fume suction structure cooperates with the exhaust fan to discharge the air passing through the fume suction structure to the electrostatic field purification device; the air intake channel of the fume suction structure is a channel inclined obliquely to the rear and downward, and the air intake channel is composed of a front oblique plate, left and right vertical plates and a rear side plate. A plurality of nozzles are provided on the top of the rear side plate. The top water curtain formed by the water sprayed simultaneously by the nozzles is sprayed onto the front oblique plate in the form of an oblique front and downward direction, and the air intake channel below the top water curtain is sequentially provided with a first mesh plate arranged obliquely to the rear and downward direction and a second mesh plate arranged obliquely to the front and downward direction from top to bottom.

At the same time, the splash prevention structures such as the brush or the steel brush adopted also have a certain filtering function, which can further ensure the purification effect of the oil fume.

[0010] A further setting of the present invention is that the left and right side edges of the first net plate and the second net plate are both folded downwards, and the folding angle is greater than 30° and less than 60°. The left and right side edges of the first net plate and the second net plate are in contact with the left and right vertical plates.

[0011] By adopting the above technical solution, the left and right side edges of the first net plate and the second net plate are both folded downwards, so that the liquid on the two net plates can be drained to the left and right vertical plates, and then a water curtain is generated at the three edges of the air inlet of the intake channel, forming a closed water curtain at the air inlet of the intake channel, which can further improve the impurity removal ability.

[0012] A further setting of the present invention is that the rear side plate and the rear side wall and the left and right side walls of the box body form a water storage cavity. An electric heating device is provided in the water storage cavity, and a detergent adding device is provided at the top of the water storage cavity.

[0013] A further setting of the present invention is that the water in the water storage cavity is pumped from the water tank by the main water pump.

[0017] By adopting the above technical solution, an upper grid plate and a sliding grid plate are configured for the oil fume suction structure, which is not only beautiful but also effectively improves the oil fume suction ability of the oil fume suction structure.

[0018] A further setting of the present invention is that the top of the air inlet channel is connected to the electrostatic field purification device, the electrostatic field purification device is connected to the fan, and the fan is directly connected to the atmosphere.

[0019] By adopting the above technical solution, the subsequent specific components of the air inlet channel are defined, and the electrostatic field purification device and the multi-layer water curtain filtration method can achieve thorough cleaning of the oil fume.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the scope of protection of the present invention. Embodiment

[0030] As Figures 1 to 2As shown in the figure, a kitchen wet smoke exhaust purification device includes a box body 1. In the middle below the front side of the box body 1, there is an oil fume suction structure 8. Right below the inlet of the oil fume suction structure 8, there is a horizontal water tank 6 arranged horizontally from left to right. Through the cooperation with the exhaust fan 3, the oil fume suction structure 8 discharges the air passing through it to the electrostatic field purification device 2; the air intake channel of the oil fume suction structure 8 is a channel inclined obliquely backward and downward. The intake channel is formed by a front inclined plate 81, left and right vertical plates, and a rear side plate 82. At the top of the rear side plate 82, there are several nozzles 83. The top water curtain 84 formed by the water sprayed simultaneously by the nozzles 83 is sprayed onto the front inclined plate 81 in a form inclined obliquely forward and downward. Inside the intake channel below the top water curtain 84, a first mesh plate 85 arranged obliquely backward and downward and a second mesh plate 86 arranged obliquely forward and downward are successively arranged from top to bottom. The left and right side edges of the first mesh plate 85 and the second mesh plate 86 are both folded downward, and the folding angle is greater than 30° and less than 60°. The left and right side edges of the first mesh plate 85 and the second mesh plate 86 are in contact with the left and right vertical plates. The rear side plate 82 and the rear side wall and left and right side walls of the box body 1 form a water storage cavity 16. An electric heating device is arranged in the water storage cavity 16, and a detergent adding device is arranged at the top of the water storage cavity 16. At the front side of the top of the oil fume suction structure 8, there is an upper grid plate 4. A sliding grid plate 5 is arranged as a slideway between the lower edge of the upper grid plate 4 and the outer edge of the water tank 6. The top of the intake channel is connected to the electrostatic field purification device 2, the exhaust pipe of the electrostatic field purification device 2 is connected to the fan 3, and the fan 3 is directly connected to the atmosphere. In the water tank 6 directly below the air intake of the intake channel, there is a liquid splash prevention structure 9, and the liquid splash prevention structure 9 is a brush or a steel brush.

[0031] Principle of use: The first mesh plate 85 first diverts the uniform water sprayed by the top water curtain 84 onto the front inclined plate 81 to the rear side plate 82, and then the second mesh plate 86 diverts the water flowing down from the first mesh plate 85 evenly onto the front inclined plate 81. At the same time, since the left and right edges of the first mesh plate 85 and the second mesh plate 86 are both folded downward by a certain angle, part of the water passing through the first mesh plate 85 and the second mesh plate 86 will also flow down from the left and right vertical plates. Finally, the water flowing out of the intake channel forms a closed water curtain through the lower edge of the left and right vertical plates and the front inclined plate 81, and the water of the closed water curtain directly drains into the water tank 6.

[0032] When the kitchen wet smoke exhaust purification device is in the operating state, the main water pump directly pumps the water in the water tank 6 into the water inlet pipe of the nozzle 83, and the nozzle 83 directly sprays to form a normal-temperature top water curtain 84; when the kitchen wet smoke exhaust purification device is in the cleaning state, the main water pump pumps the water in the water tank 6 into the water storage cavity 16. After the water in the water storage cavity 16 is heated to the set temperature and mixed sufficiently with the cleaning agent, the cleaning water pump sends the cleaning liquid in the water storage cavity 16 to the water inlet pipe of the nozzle 83, and the nozzle 83 directly sprays to form a high-temperature top water curtain to clean the inner wall of the intake channel and the first mesh plate 85 and the second mesh plate 86.
