Description

Technical Field

[0001] The utility model belongs to the field of oil fume purification integrated machines, and relates to an automatic cleaning type fume hood integrated machine. Background Art

[0002] The hot processing area of ​​the kitchen is the core area of ​​cooking activities. Under high temperature and high humidity, a large amount of oil smoke is generated. These oil smoke not only contains grease particles, but also contains a variety of harmful substances, such as volatile organic compounds (VOCs), carbon monoxide, nitrogen oxides and polycyclic aromatic hydrocarbons. If these oil smoke are not removed or purified in a timely and effective manner, they will accumulate in the kitchen environment, forming difficult-to-clean oil stains and may penetrate into the walls, floors and ceilings. Long-term exposure to such an environment will not only affect the hygiene of the kitchen, but also pose a potential threat to the health of the staff, including respiratory diseases, skin problems and other related health risks.

[0003] Traditionally, range hoods are used to initially degrease oil fumes before exhausting them to the outdoors through a flue. However, this method has significant limitations, as conventional range hoods have low removal efficiency and are unable to completely remove fine particulate matter and harmful gases from oil fumes. With rising environmental awareness and technological advancements, more efficient oil fume purification equipment has gradually been introduced to the market, particularly in commercial kitchens, where its use is growing. Integrated systems that combine fume hoods and oil fume purification functions are gaining popularity due to their space-saving, easy installation, and relatively simple maintenance.

[0004] Despite this, existing fume hood and fume purification systems still face challenges during use. One of the most prominent issues is the accumulation of oil smoke and dirt on internal components. Due to the equipment's prolonged operation in a highly greasy environment, a large number of tiny oil droplets that are not fully captured gradually deposit on the surfaces of filters, impeller blades, and other key components, forming stubborn stains. This not only reduces fume purification efficiency but can also lead to frequent mechanical failures, shorten equipment lifespan, and increase energy consumption.

[0005] To address this challenge, the current common practice is to periodically manually disassemble and clean the interior of the equipment. However, this approach has numerous drawbacks: first, it is extremely time-consuming and labor-intensive; second, it requires the use of a strong alkaline detergent to effectively remove grease, which can cause secondary environmental pollution. Furthermore, the cleaning effect is poor, making it difficult to thoroughly clean the interior of the housing and purification components. Furthermore, the complex structure makes it difficult to fully and thoroughly clean every corner. Therefore, the development of a new integrated fume hood system that can automate the cleaning process has become particularly important. Summary of the Invention

[0007] a housing, wherein an air inlet and an air outlet are provided on the housing;

[0009] A purification component, disposed in the housing, for purifying oil smoke;

[0010] The oil smoke enters the shell from the air inlet, is purified by the purification component, and is discharged from the air outlet.

Based on the embodiments in 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.

[0036] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the scope of protection of the present invention. The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings.

[0037] An automatic cleaning type smoke hood integrated machine, such as Figures 1-13 As shown, it includes a housing 1, a purification component arranged in the housing 1, and a cleaning structure inside the housing 1. The housing 1 is provided with an air inlet and an air outlet, and a fan is provided at the air outlet. The purification component includes an electric field component 3 for purifying oil smoke. Of course, the purification component can also be provided with a wire mesh demister for water removal and filtration and a UV lamp for removing odors. The wire mesh demister is configured as an SP wire mesh demister. The electric field component 3 includes a primary charging electric field and a two-stage adsorption electric field. A cyclone plate 11 is provided at the air inlet. The oil smoke in the space enters the housing 1 through the cyclone plate 11. When the wire mesh demister and UV lamp are provided, the oil smoke first passes through the wire mesh demister to filter the water and particulate matter on the oil smoke. The electric field component 3 then performs a three-stage filtration. After being deodorized by the UV lamp, it is finally discharged from the housing 1 by the fan. When only the electric field component 3 is provided, the oil smoke enters the cyclone plate 11 and directly passes through the three-stage filtration of the electric field component 3 before being discharged from the housing 1. The cleaning structure provided in this solution is mainly used to clean the electric field component 3.

[0038] like Figure 1 、 Figure 2 As shown, the shell 1 includes a first chamber, a second chamber and a third chamber arranged in sequence, the cleaning structure and the wire mesh demister are both arranged in the first chamber, the electric field component 3 is arranged in the second chamber, the UV lamp and the blower are arranged in the third chamber, the air outlet of the third chamber is the air outlet of the shell, and the cleaning structure is arranged in the first chamber to facilitate flushing of the electric field component 3. At the same time, because the first chamber is the first chamber through which the oil smoke passes, the oil content will be greater than that of the other two chambers. Being arranged in the first chamber can also clean the first chamber. During the cleaning process, it is necessary to ensure that the interior of the shell 1 is closed to prevent the steam from cooling or escaping from the shell 1. Therefore, an automatic air valve 4 is provided on the shell 1. The automatic air valve 4 is provided at the bottom of the first chamber, between the second chamber and the third chamber. When cleaning is required, the automatic air valve 4 is closed, and when the oil smoke needs to be purified, the automatic air valve 4 is opened. Of course, it can also be provided at the inlet and outlet ends of each chamber, but the provision is cumbersome and consumes a large amount of materials.

[0039] like Figure 2 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 as well as Figure 13As shown, the automatic damper 4 is configured as a louver type, including four enclosed fixed rods 41, a rotating rod 43 provided on the fixed rods 41, and a plurality of blades 42 fixed on the rotating rod 43. The more blades 42 are provided, the more uniform the air intake is, but the flow of oil smoke is less likely to occur. The fewer blades 42 are provided, the easier the oil smoke is to flow, but the flow of oil smoke is more uneven. The blades 42 include a windshield 421 and a connecting portion connected to the windshield 421. The connecting portion includes a first connecting portion 422 and a second connecting portion 423 provided at an angle. The angle between the first connecting portion 422 and the second connecting portion 423 is less than or equal to 90°. The first connecting portion 422 is connected to the windshield 421. When the automatic damper 4 is closed, one end of the blade 42 will be placed on the adjacent blade 42 to ensure the sealing effect and prevent the blade 42 from swinging downward due to gravity and being unable to be closed. Reinforcing ribs are provided on the blades 42.

[0040] like Figure 10 、 Figure 12 as well as Figure 13 As shown, a first limiting rod 44 and a second limiting rod 45 are provided on the fixed rod 41. The rotating rod 43 is provided at the angle where the wind shield 421 and the first connecting portion 422 are connected, so as to facilitate the rotation of the blade 42 and the swing of the blade 42 around the rotating rod 43. The first limiting rod 44 is provided on one side of the closing direction of the blade 42, and the second limiting rod 45 is provided on the side of the first connecting portion 422 away from the first limiting rod 44. The position of the first limiting rod 44 needs to be within the rotation range of the second connecting portion 423, and the position of the second limiting rod 45 needs to be within the rotation range of the first connecting portion 422. The first limiting rod 44 and the second limiting rod 45 jointly limit the rotation angle of the blade 42. When the automatic air valve 4 is opened, the blade 42 rotates following the wind direction, and the second connecting portion 423 abuts against the first limiting rod 44 to limit the opening angle of the blade 42. When the automatic air valve 4 is closed, the blade 42 rotates against the wind direction, and the first connecting portion 422 abuts against the second limiting rod 45 to limit the angle of the blade 42 when it is closed.

[0041] like Figure 13 As shown, in order to better protect the blade 42, a fixing member is fixed on the blade 42, and the fixing member includes a first side and a second side connected at an angle. The first side of the fixing member is connected to the wind shield portion 421 by rivets, and the second side is connected to the first connecting portion 422 by rivets. The rotating rod 43 is set at the bend of the fixing member.

[0042] When the range hood needs to extract oil smoke, the fan is turned on. Due to the suction force of the fan, the automatic air valve 4 opens, and the blades 42 rotate following the wind direction to start the purification operation. When the range hood needs to be cleaned, the fan is turned off, and the blades 42 naturally drop due to gravity. The automatic air valve 4 is closed, and the interior of the shell 1 is closed, thereby ensuring the temperature of the steam in the shell 1 and further ensuring the cleaning efficiency of the range hood.

[0043] During the long-term use of the smoke hood all-in-one machine, a large amount of oil and dirt will stick to the shell 1 and the electric field component 3 that plays the main purification role. If there is too much oil and dirt on the electric field component 3, it will affect the subsequent purification effect. It is difficult to remove the electric field component 3 for cleaning. Therefore, a cleaning structure is set to clean the electric field component 3 and the shell 1.

[0044] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 Figure 7 as well as Figure 8 As shown, the cleaning structure includes a delivery main pipe 21 for delivering steam, a rotating shaft 23 rotatably connected to the delivery main pipe 21, a connecting pipe 25 connected to the rotating shaft 23, and a steam nozzle 23 connected to the connecting pipe 25; the steam nozzle 23 rotates around the center point to form a circular surface 5, the line passing through the center point and perpendicular to the circular surface 5 is the central axis, the plane passing through the jet outlet of the steam nozzle 23 and the central axis is the first plane, and the plane perpendicular to the first plane and passing through the jet outlet is the second plane; the steam injection direction forms a first angle with the central axis in the orthographic projection view of the first plane, and forms a second angle with the radial direction of the circular surface 5 in the orthographic projection view of the second plane. The steam injection direction in this scheme will have two directional components after the steam is ejected, one is the first component toward the electric field component 3, and the other is the second component toward the rotation direction. The components in two directions can ensure that the steam nozzle 23 sprays steam toward the electric field component while rotating without power; when the steam is ejected toward the electric field component 3, it drives the steam nozzle 23 and the connecting pipe 25 to rotate around the rotation axis 22, and the steam rotates forward, so that the cleaning area is larger and the cleaning effect is better.

[0045] A nozzle bevel 231 is provided at the end of the steam nozzle 23. The nozzle bevel 231 is configured as a fan-shaped surface and is disposed on a side close to the electric field assembly 3. The nozzle bevel 231 is disposed perpendicular to the steam ejection direction. The jet port 232 of the steam nozzle 23 is disposed on the nozzle bevel 231. The provision of the bevel allows for a better arrangement of the jet port of the steam nozzle 23. Steam is ejected from the jet port 232 toward the electric field assembly 3, and the steam cleans the electric field assembly 3 and the housing 1 in a rotating manner, resulting in a high cleaning efficiency. A support beam is provided in the first cavity, the support beam being connected to the housing 1. The transport manifold 21 is detachably connected to the support beam near the steam nozzle 23 to prevent shaking when the steam nozzle 23 rotates.

[0046] A plurality of steam spray heads 23 are provided, each connected to a connecting pipe 25, and the connecting pipes 25 are evenly arranged on the rotating shaft 22. In this embodiment, three steam spray heads 23 are provided. Two main delivery pipes 21 are provided, each connected to three steam spray heads 23 to ensure a good cleaning effect.

[0047] When the steam nozzle 23 is directed toward the electric field assembly 3 for cleaning, the central portion of the electric field assembly 3 is mainly cleaned. The two ends of the electric field assembly 3 may not be cleaned thoroughly, especially the insulators that are greasy and easily cause malfunctions. Therefore, at least one delivery branch pipe 24 is extended from the delivery main pipe 21. The length of the delivery branch pipe 24 covers the entire electric field assembly 3. The delivery branch pipe 24 is provided with a plurality of spray holes 241 for spraying steam toward the electric field assembly 3. The plurality of spray holes 241 are evenly arranged. In this solution, two delivery branch pipes 24 are provided. The two delivery branch pipes 24 are arranged at both ends of the purification assembly to clean the two ends of the electric field assembly 3 and the insulators. Through the dual coordination of the cleaning structure and the delivery branch pipe 24, the housing 1 and the entire electric field are fully cleaned, and the cleaning effect is guaranteed.

[0048] The transport main pipe 21 is externally connected to a steam generator.

[0049] The utility model is an automatic cleaning type smoke hood integrated machine, which can achieve the following technical effects: a rotatable steam nozzle 23 is provided, steam is ejected from the jet port of the steam nozzle 23, and the steam ejection direction is set between the first direction and the second direction, so that after the steam is ejected, there is a component force toward the electric field component 3 and a component force toward the rotation direction, so that the steam nozzle can rotate, so that the steam enters the shell 1 in a rotating form to clean the oil smoke in the shell 1, and the rotating nozzle rotates 360 degrees to cover every corner inside the shell 1 to avoid cleaning dead corners. By spraying high-temperature steam, the oil smoke and dirt are effectively dissolved, and the cleaning effect is improved. By steam cleaning, no chemicals are needed, and the cleaning process is simple and pollution-free. The switch of the automatic air valve 4 is directly controlled by the fan to ensure that the shell 1 is closed during cleaning, and the steam temperature is controlled. The higher the temperature of steam, the better the cleaning effect. The automatic air valve 4 is controlled to open during purification, with a high degree of automation and easy operation. At the same time, two automatic air valves 4 are provided to isolate and clean the cavity and purification component contaminated with oil and dirt, ensuring the purification effect.
