Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0028] In the description of this application, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on this application.

[0029] In the description of this application, "a plurality" means more than two, and "greater than," "less than," "exceed," etc. are understood to exclude the number itself. The terms "first" and "second" are used solely to distinguish technical features and are not to be construed as indicating or implying relative importance, or implicitly specifying the number or order of the technical features indicated.

[0030] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0031] 1 to 3 , a built-in range hood includes a main housing 100, a fan 300, an air outlet duct 400, and a purification component 500; the main housing 100 extends upward to an air inlet housing 200, and the main housing 100 is divided into a first housing chamber 110 and a second housing chamber 120, the first housing chamber 110 and the second housing chamber 120 are connected through a ventilation hole, and the second housing chamber 120 leads to the inner cavity of the air inlet housing 200; the fan 300 is installed in the first housing chamber 110, and the air inlet of the fan 300 is connected to the ventilation hole; the air outlet duct 400 is installed at the air outlet at the bottom of the fan 300; and the purification component 500 is installed on the air outlet duct 400.

[0032] First, during installation, the embedded range hood is installed as a whole in a cabinet. The cabinet countertop is provided with an air intake vent, which is located behind the cooker. The air intake vent of the air intake housing 200 is located below the air intake vent. At the same time, the volume of the main housing 100 embedded in the cabinet is very small, so that the front of the main housing 100 can accommodate other embedded products such as a steam oven, a dishwasher, a disinfection cabinet, and a drawer cupboard without increasing the width of the cabinet. Existing standard-sized cabinets can be used, which will not be affected during installation and can adapt to the installation and placement requirements of cabinets in different areas.

[0033] Secondly, when sucking oil smoke, the oil smoke passes through the "L"-shaped air duct 501, that is, enters the inner cavity of the air inlet shell 200, is laterally sucked in by the fan 300 in the second shell chamber 120, and is then discharged through the air outlet pipe 400 installed at the bottom of the fan 300, making it have the characteristics of high wind pressure, low speed and low noise.

[0034] Again, the purification component 500 filters, removes odors, sterilizes, dries, etc. the oil smoke that passes through, making the exhaust gas very clean.

[0035] As shown in Figure 4, since the air inlet of the air inlet housing 200 is located below the air suction port, soup can easily flow into the air inlet housing 200 and the main body of the main body 100 through the air suction port, which can easily cause damage to the circuit. At the same time, since it is difficult to clean, it leads to the generation of odor. Therefore, a first water receiving box 600 is also movably installed in the air inlet housing 200. The first water receiving box 600 receives the incoming soup and is convenient for cleaning.

[0036] At the same time, a filter screen 900 is installed in the first water receiving box 600. The filter screen 900 is made of multi-layer stainless steel wire filter screen. The filter screen 900 can separate the passing oil smoke and grease. After separation, the filtered oil and water are received by the first water receiving box 600. When cleaning, you only need to take out the first water receiving box 600 for cleaning.

[0037] 4 , an upper water leakage hole 130 and a lower water leakage hole 140 are further provided on the main body shell 100. The upper water leakage hole 130 is located below the first water receiving box 600, and a second water receiving box 700 is detachably installed below the lower water leakage hole 140. The second water receiving box 700 is used to receive soup overflowing from the first water receiving box 600, or to collect oil and water accidentally poured in or accumulated over a long period of use, and to clean it in a timely manner.

[0038] As shown in Figure 2, the purification component 500 is divided into a first purification component 510 and a second purification component 520; the first purification component 510 is installed between the air outlet of the fan 300 and the air inlet of the air outlet pipe 400, and the second purification component 520 is detachable and installed at the air outlet of the air outlet pipe 400. Because the second purification component 520 is filled with activated carbon, the second purification component 520 can be replaced after long-term use, and can be removed, cleaned with water, dried, and reused, which increases the service life and is very environmentally friendly.

[0039] 5 , specifically, the first purification component 510 includes a first housing 511 , a UV lamp 512 , and an ionized ozone generator 513 . An air duct 501 is provided in the first housing 511 . The air duct 501 is used to connect the fan 300 and the air outlet pipe 400 . The light emitted by the UV lamp 512 is directed toward the air duct 501 . The ionized ozone generator 513 is used to deliver ozone into the air duct 501 .

[0040] An electrical chamber 502 is also provided in the first housing 511, and an ionization ozone generator 513 is installed in the electrical chamber 502. An oxygen outlet 503 is provided on the electrical chamber 502, and the oxygen outlet 503 leads to the air duct 501; an irradiation hole 504 is provided on the side wall of the air duct 501, and a UV lamp 512 is installed on the outside of the first housing 511. The light emitted by the UV lamp 512 is emitted into the air duct 501 through the irradiation hole 504.

[0041] The ionization ozone generator 513 can ionize the air to form ozone; ozone is a strong oxidant that can destroy the cell walls of bacteria, thereby diffusing into the cells and oxidizing and decomposing the glucose oxidase necessary for bacteria to oxidize glucose. It can also directly react with bacteria and viruses, thereby destroying the metabolism and reproduction process of bacteria; in addition, ozone can decompose odorous gases such as ammonia, benzene, and hydrogen sulfide, thereby playing a deodorizing role. The sterilization, disinfection and deodorization of ozone are short in time and strong in effect.

[0042] The UV lamp 512 can generate ultraviolet rays, thereby killing bacteria and viruses in the air duct 501, and decomposing ozone so that it can be discharged indoors or outdoors after purification. The ultraviolet rays can generate 254nm ultraviolet rays.

[0043] When the oil smoke enters the air duct 501 from the range hood, the ozone-containing gas will continue to enter the UV lamp 512. Under the synergistic effect of ultraviolet light, the ozone-containing gas effectively destroys the molecular structure of organic matter and eventually decomposes it due to the formation of hydroxyl free radicals. After the ozone is deodorized, the ultraviolet light kills bacteria and viruses, and the ultraviolet light decomposes the ozone, the clean gas is discharged indoors or outdoors. The gas is cleaner and the gas after decomposition of the ozone will not be harmful to the human body.

[0044] 6 , specifically, the second purification component 520 includes a second housing 521 , a first filter screen 522 , and a second filter screen 523 . The first filter screen 522 and the second filter screen 523 are respectively installed at both ends of the second housing 521 . The first filter screen 522 is filled with zeolite, and the second filter screen 523 is filled with activated carbon.

[0045] The oil smoke first passes through the zeolite in the first filter screen 522 and then passes through the activated carbon in the second filter screen 523, which adsorbs odor molecules such as ozone, sulfur dioxide, hydrogen sulfide, etc. in the gas, oxidizes and separates them, thereby eliminating the odor and making the exhausted gas cleaner.

[0046] First of all, zeolite is an inorganic crystalline material with a regular pore structure, strong acidity and high hydrothermal stability. There are many uniformly sized pores distributed in the middle of zeolite, which can screen various fluid molecules according to their effective pore size. When gases containing ozone and odor flow through, some ozone and odor molecules in the gas move irregularly and collide with its surface and are adsorbed on its surface, resulting in molecular concentration on the surface. At the same time, under the application of catalysts, they are decomposed and catalyzed, thereby achieving the purpose of eliminating ozone and removing odors.

[0047] Secondly, honeycomb activated carbon can effectively remove harmful gases, odors and pollutants in the air, such as sulfide, ammonia, formaldehyde, etc.

[0048] 1 , the bottom of the main body housing 100 is provided with adjustable support legs 1000 , and the installation height of the entire machine can be adjusted by adjusting the support legs 1000 according to cabinets of different heights.

[0049] 2 to 4 , a filter screen 900 is installed in the first water receiving box 600, and an air inlet grille 800 is installed on the top opening of the first water receiving box 600. In addition, a glass panel is installed on the surface of the cabinet, and a glass windshield is also installed on the glass panel. The glass panel is located behind the air inlet grille 800, and the glass panel can be quickly docked and locked with the air inlet housing 200, thereby solving the problem of complicated installation steps.
