Description

[0002] In the modern kitchen environment, the range hood as an important air purification equipment, its main function is to absorb and handle the oil fume and peculiar smell generated in the cooking process. However, the traditional range hood often faces a significant problem when dealing with oil fume: because the oil fume contains a large amount of oil gas medium, and these media are gaseous at high temperature, so after the range hood preliminarily absorbs the oil fume, it is difficult to effectively separate these oil gas media from the air.

[0003] When the oil fume is sucked into the range hood, it usually goes through one or more filter screens for preliminary filtration. However, these filter screens can only filter out large particles of oil fume and impurities, and are difficult to effectively intercept tiny oil gas media. These tiny oil gas media remain gaseous at high temperature, and flow into the centrifugal fan part of the range hood with the oil fume.

[0004] Under the action of the centrifugal fan, the oil fume is further compressed and accelerated, making it more difficult to separate the oil gas medium. When these oil gas media cool down in the subsequent process, they are easily attached to the blades of the centrifugal fan, forming a layer of oil dirt that is difficult to remove. This not only reduces the purification efficiency of the range hood, but also may cause obstacles to the normal operation of the range hood, and even shorten the service life of the range hood.

[0005] Therefore, it is necessary to invent a kitchen air purification device. UTILITY MODEL CONTENTS

For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0025] As shown in the accompanying Figure 1 to the accompanying Figure 4 illustrated:

[0026] The kitchen air purification device provided by the utility model, including the range hood cover 1, the oil smoke fan 2, the cover panel 3, the panel clamping cover 4, the filter screen plate 5, the water film coagulator 6 and the cooling water tank 7, the oil smoke fan 2 is arranged in the range hood cover 1, the cover panel 3 integrally arranged on the range hood cover 1 is externally provided with the panel clamping cover 4, the filter screen plate 5 and the water film coagulator 6 are arranged at the panel clamping cover 4, and the water film coagulator 6 is communicated with the cooling water tank 7 arranged on the cover panel 3.

[0027] Further, the filter screen plate 5 is ingeniously arranged outside the water film coagulator 6, and a certain spacing is maintained between the two. Such design not only ensures that the oil fume can smoothly enter the water film coagulator 6 for further purification treatment after being preliminarily filtered through the filter screen plate 5, but also avoids direct contact between the filter screen plate 5 and the water film coagulator 6, reducing the performance decline caused by blockage or wear.

[0028] Further, the water film coagulator 6 includes a fixed seat 61, a water injection box 62, a backflow water box 63, a water film cooling pipe A 64, a water film cooling pipe B 65 and a cooling water film 66, two fixed seats 61 are firmly clamped in the cover panel 3, which provides stable support for the water injection box 62 and the backflow water box 63. Each fixed seat 61 is provided with a clamping slot for clamping the water injection box 62 and the backflow water box 63. The water injection box 62 and the backflow water box 63 are both hollow rectangular box structures, which are communicated with the cooling water tank 7, ensuring the circulation of cooling water.

[0029] Further, the water injection box 62 is transversely arranged with a plurality of water film cooling pipes A 64 and water film cooling pipes B 65, one end of which is connected with the backflow water box 63. The water film cooling pipes A 64 and the water film cooling pipes B 65 are the same structure, and they are arranged on the opposite side of each other. Such a layout not only optimizes the cooling effect, but also ensures the uniform distribution of cooling water. The liquid medium in the water injection box 62 flows to the backflow water box 63 through the water film cooling pipes A 64 and the water film cooling pipes B 65, forming a complete cooling water circulation.

[0030] Further, the cooling water film 66 is another key component, which is provided with two, and a certain interval is maintained between the two cooling water films 66. The cooling water film 66 is composed of a sleeve part and a main body part, and a plurality of through holes are uniformly distributed on the main body part. These through holes enable the cooling water film 66 to fully contact the oil fume, thereby improving the separation efficiency of the oil and gas medium. The sleeve part of the cooling water film 66 allows the water film cooling pipe A 64 or the water film cooling pipe B 65 to pass through, ensuring that the cooling water can smoothly flow through the cooling water film 66, achieving efficient heat exchange.

[0031] Further, the cooling water tank 7 pumps the liquid medium in itself to the water injection box 62 through the pump body, and the liquid medium in the water injection box 62 flows to the backflow water box 63 through the water film cooling pipes A 64 and the water film cooling pipes B 65. The liquid medium in the backflow water box 63 finally flows back to the cooling water tank 7, forming a complete cooling water circulation system. This design not only ensures the continuous supply of cooling water, but also improves the efficiency and stability of oil fume purification.

[0032] The working principle is as follows: first, start the oil smoke fan 2, the oil smoke fan 2 inside the hood 1 starts to work, generates strong suction, and absorbs the oil smoke generated in the cooking process from the kitchen. The oil smoke first encounters the filter screen plate 5 outside the hood panel 3, which preliminarily filters the oil smoke, intercepts larger oil smoke particles and impurities, and ensures that the oil smoke entering the water film coagulator 6 is relatively pure.

[0033] Then, the preliminarily filtered oil smoke passes through the gap between the filter screen plate 5 and the water film coagulator 6, and enters the inside of the water film coagulator 6. Here, the oil smoke encounters the cooling water film 66, which is composed of two cooling water films 66 with a certain interval. Each cooling water film 66 is composed of a sleeve part and a main body part, and a plurality of through holes are uniformly distributed on the main body part. These through holes enable the cooling water film 66 to fully contact the oil smoke, increasing the area and efficiency of heat exchange.

[0034] At the same time, the cooling water tank 7 pumps the cooling water in itself to the water injection box 62 through the pump body. The cooling water in the water injection box 62 flows to the backflow water box 63 through the transversely arranged water film cooling pipe A 64 and the water film cooling pipe B 65. The water film cooling pipe A 64 and the water film cooling pipe B 65 are the same structure, and they are arranged opposite to each other on the side of the other. Such arrangement ensures that the cooling water can be uniformly distributed, and optimizes the cooling effect. In the process of flowing, the cooling water penetrates into the pipe sleeve part of the cooling water film 66, exchanges heat with the oil fume, condenses and adsorbs the oil gas medium in the oil fume on the cooling water film 66.

[0035] With the continuous circulation of the cooling water, the condensed oil gas medium and the cooling water flow into the backflow water box 63 together. The liquid medium in the backflow water box 63 finally flows back to the cooling water tank 7, forming a complete cooling water circulation system. In the cooling water tank 7, the cooling water can be restored to its cooling capacity through appropriate treatment (such as filtration, cooling, etc.) so as to be pumped into the water injection box 62 for use again.

[0036] In the whole working process, the filter screen plate 5 and the water film condenser 6 cooperate together to realize efficient purification of the oil fume. The preliminary filtering effect of the filter screen plate 5 reduces the oil fume particles and impurities entering the water film condenser 6, and the water film condenser 6 condenses and adsorbs the oil gas medium in the oil fume on the cooling water film 66 through the circulation of the cooling water film 66 and the cooling water, realizing effective separation of the oil gas medium. This design not only improves the efficiency and stability of oil fume purification, but also prolongs the service life of the range hood.

[0037] The technical scheme disclosed in the utility model, or the technical scheme designed by the person skilled in the art under the inspiration of the technical scheme of the utility model, and the similar technical scheme achieving the above technical effects all fall within the protection scope of the utility model.
