Description

Technical Field

[0001] The present application relates to the technical field of kitchen fume purification, and in particular to a kitchen and bathroom lamp with an oil fume purification function. Background Art

[0002] As the most fume-producing area in a home, the kitchen's removal is a key consideration during renovations and kitchenware installation. This lingering fumes not only impact the environment, but also corrode and damage walls, appliances, and other fixtures over time. Furthermore, inhaling large amounts of fumes can cause serious harm to the human body. Therefore, removing kitchen fumes is essential to maintaining a comfortable kitchen environment and enhancing residential comfort.

[0003] Currently, kitchen fumes are primarily handled through range hoods, which extract and exhaust them as they are generated, preventing them from stagnating in the kitchen and causing choking or breathing difficulties. There are also many range hoods and other devices with fume extraction functions available on the market. Furthermore, some home designs and decorating practices incorporate fresh air systems in the kitchen, supplying fresh air and exhausting fumes through windows or ventilation points.

[0004] Range hoods, equipment with exhaust functions, and fresh air systems are generally effective only when large quantities of oil smoke are present in the kitchen. Small amounts of oil smoke may not be effectively exhausted. Furthermore, small amounts of oil smoke permeate the kitchen space, accumulating over time to form oil and breed bacteria. To combat bacterial growth caused by small amounts of oil smoke, UV lamps are often installed on lighting fixtures for disinfection. However, this only provides superficial disinfection and does not eliminate the underlying cause of bacterial growth.

[0005] Therefore, designing a kitchen and bathroom lamp that can purify the oil smoke, thoroughly purify the oil smoke, and eliminate the breeding of bacteria from the source is a problem that needs to be solved urgently. Summary of the Invention

[0006] The present application provides a kitchen and bathroom lamp with an oil fume purification function. The ultraviolet lamp is arranged on the inner side of the outer panel, which can prevent the ultraviolet lamp from being exposed to the outside and causing long-term exposure of the ultraviolet lamp to people, which affects human health. A special oil fume purification channel is opened, and the ultraviolet lamp is installed on the lamp holder set in the channel. The ultraviolet lamp is moved by the lamp guide device, thereby increasing and decreasing the area and intensity of the ultraviolet lamp irradiation, which can purify the oil fume in a reasonable manner and improve the energy utilization and purification efficiency to a certain extent. The smoke baffle can buffer and absorb the incoming oil fume to a certain extent, avoiding the situation where the oil fume flow is too large and cannot be completely purified. It thoroughly purifies the oil fume and eliminates the breeding of bacteria at the source.

[0007] The present application provides a kitchen and bathroom lamp with an oil fume purification function, comprising an outer panel, an inner top panel, a lamp holder, an exhaust device, a lamp guiding device, an ultraviolet lamp, a smoke shield, a smoke inlet pipe, a smoke exhaust pipe and an electrified connecting piece; the outer panel and the inner top panel are arranged opposite to each other; the lamp holder is arranged between the outer panel and the inner top panel, and is close to the inner top panel; a lamp guiding space is formed between the lamp holder and the inner top panel; a purification space is formed between the lamp holder and the outer panel; a smoke inlet and a smoke exhaust port are respectively provided at opposite ends of the outer panel; the smoke inlet is connected to the purification space through the smoke inlet pipe; the smoke exhaust port is connected to the purification space through the smoke exhaust pipe; the lamp guiding device is located in the lamp guiding space; the lamp guiding device is arranged on the lamp holder, and is close to the smoke exhaust port; the ultraviolet lamp is arranged in the lamp guiding space, and the ultraviolet lamp is connected to the lamp guiding device; the exhaust device is arranged in the purification space, and is close to the smoke exhaust port; the smoke shield is arranged in the purification space, and is close to the smoke inlet; the electrified connecting piece is located in the lamp guiding space, and is arranged on the inner top panel.

[0008] During the above implementation process, the UV lamp is set on the inner side of the outer panel to avoid the UV lamp being exposed to the outside and causing ultraviolet light leakage, which can affect human health due to long-term exposure. A special oil fume purification channel is opened between the outer panel 01 and the inner top plate 02, in which the lamp holder is located, and the UV lamp is installed on the lamp holder. The UV lamp can be moved by the lamp guide device to increase or decrease the area irradiated by the UV lamp, which can purify the oil fume accordingly, thereby improving the energy utilization and purification efficiency to a certain extent. The smoke baffle can buffer and absorb the incoming oil fume to a certain extent, avoiding the situation where the oil fume flow is too large and cannot be completely purified.

[0009] Optionally, in one embodiment, the ultraviolet lamps are arranged in sequence on the lamp holder and connected to each other to form an ultraviolet lamp group; one end of the ultraviolet lamp group is close to the lamp guide device and connected to the lamp guide device, and the other end extends to a position corresponding to the smoke inlet; the power connection piece is located in the lamp guide space, and the power connection piece corresponds to the purification space.

[0010] During the above implementation process, the ultraviolet lamps are connected to each other to form a lamp group, and the lamp guiding device controls the amount of ultraviolet light irradiated to the purification space. It can achieve efficient and energy-saving purification for oil smoke of different concentrations and flow rates, which not only improves the utilization rate of energy, but also fully realizes the purification of oil smoke.

[0011] Optionally, in one embodiment, the ultraviolet light emitted by the ultraviolet lamp has a wavelength of 185 nm and 254 nm.

[0012] During the above-mentioned implementation process, the ultraviolet lamp in this band produces ultraviolet rays and ozone, and further generates hydroxyl free radicals. The synergistic effect of these three factors (ultraviolet rays, ozone, and hydroxyl free radicals) completely decomposes the organic matter in the oil smoke into water and carbon dioxide. The purified air is discharged through the outlet. Due to the action of the ultraviolet lamp, the air is also sterilized and disinfected at the same time.

[0013] Optionally, in one embodiment, the lamp guiding device includes a hydraulic actuator, a hydraulic source and a controller; the piston rod of the hydraulic actuator is connected to the ultraviolet lamp group; the hydraulic source is connected to the hydraulic actuator; and the controller is connected to the hydraulic source and the exhaust device at the same time.

[0014] During this process, the lamp guide mechanism uses a hydraulic actuator to move the UV lamp assembly. Simultaneously, a controller collects parameters and controls the movement of the UV lamp based on the exhaust system's operating conditions, achieving efficient and energy-saving fume purification. Furthermore, the hydraulic actuator provides stable movement, preventing violent shaking during movement, which could prevent the UV lamp assembly from losing contact with the power connector or damaging the assembly.

[0015] Optionally, in one embodiment, the diameter of the smoke inlet pipe gradually increases from the end close to the smoke inlet to the end close to the purification space; the end of the smoke inlet pipe close to the purification space is connected to the lamp holder and the outer panel at the same time to close the purification space.

[0016] During the above implementation, the diameter of the smoke inlet pipe is increased from small to large, which can further slow the flow rate of oil smoke into the purification space, ensuring that the oil smoke can be fully purified in the purification space. At the same time, the diameter of the smoke inlet pipe near the smoke inlet is smaller, and the air intake volume is relatively small, which can also play a role in flow control to a certain extent.

[0017] Optionally, in one embodiment, the smoke shield is arranged at one end of the smoke inlet pipe close to the purification space; the smoke shield is spaced apart from the lamp holder; and the smoke shield is spaced apart from the outer panel.

[0018] During the above implementation process, the smoke baffle is located at the position of the smoke inlet pipe close to the purification space. It can play a certain flow limiting role when the smoke intake is large. At the same time, it can also absorb and block part of the oil smoke, achieving a certain degree of oil control and purification effect.

[0019] Optionally, in one embodiment, an oil accumulation groove is embedded in the outer panel at a position corresponding to the smoke shield; a drainage column is provided at one end of the smoke shield close to the oil accumulation groove, and the end of the drainage column away from the smoke shield is located in the oil accumulation groove.

[0020] In the above implementation process, the oil trough is used to collect the oil blocked by the smoke shield, preventing the oil on the smoke shield from dripping onto the outer panel and causing corrosion to the outer panel. The drainage column can play a guiding role, preventing the oil from dripping onto the outer panel and splashing onto the outer panel.

[0021] Optionally, in one embodiment, the diameter of the smoke exhaust pipe gradually decreases from the end close to the exhaust device to the end close to the smoke exhaust port; the smoke exhaust direction of the smoke exhaust pipe at the smoke exhaust port is toward the side away from the smoke inlet.

[0022] During this implementation, the diameter of the exhaust pipe gradually decreases along the direction of the airflow, which can increase the flow rate to a certain extent, allowing the purified air to be discharged quickly, avoiding accumulation in the oil exhaust pipe and preventing the purified air from flowing back. At the same time, due to the accelerated air flow, after the purified air is discharged away from the smoke inlet, it can accumulate oil smoke in the exhaust area in other spaces, forming a certain degree of spatial circulation and enhancing the purification effect.

[0023] Optionally, in one embodiment, the exhaust device includes a guide plate and an exhaust fan; the exhaust fan is connected to the lamp holder; the guide plate is located in the purification space; the guide plate is arranged at an angle, and one end is connected to the outer panel, and the other end is connected to the end of the exhaust fan away from the lamp holder.

[0024] During the above implementation, the exhaust fan is connected to the lamp holder to prevent oil smoke from entering the lamp space through the gap between the exhaust fan and the lamp holder, thereby affecting the lamp device and UV lamp. The deflector not only guides the purified air in the space below the exhaust fan to be discharged through the exhaust fan, preventing stagnation and improving the purification effect, but also provides a certain support function, strengthening the outer panel structure.

[0025] Optionally, in one embodiment, in the direction from the smoke inlet pipe to the smoke exhaust pipe, the exhaust fan is closer to the smoke exhaust pipe than the light guide device.

[0026] During the above-mentioned implementation process, the exhaust fan is closer to the smoke exhaust pipe than the lamp guide device. In this way, the purification space below the lamp guide device provides sufficient purification reaction area for the generated ozone and hydroxyl free radicals, so that the purification reaction can occur better and efficient purification can be achieved, avoiding the situation where the ozone and hydroxyl free radicals formed by the ultraviolet lamp are discharged by the exhaust fan before they have time to undergo purification reaction.

[0038] The present embodiment provides a kitchen and bathroom lamp with an oil fume purification function. The kitchen and bathroom lamp with an oil fume purification function can completely purify a small amount of oil fume remaining in the kitchen space, thereby eliminating bacterial growth at the source.

[0039] See Figure 1 , Figure 1 This is a structural schematic diagram of a kitchen and bathroom lamp with oil fume purification function provided by an embodiment of the present invention.

[0040] The kitchen and bathroom lamp with oil fume purification function provided by the embodiment of the present invention includes an outer panel 01, an inner top panel 02, a lamp holder 03, an exhaust device 04, a lamp device 05, an ultraviolet lamp 61, a smoke shield 100, a smoke inlet pipe 08, a smoke exhaust pipe 09 and an electric connection piece 07; the outer panel 01 is arranged opposite to the inner top panel 02; the lamp holder 03 is arranged between the outer panel 01 and the inner top panel 02 and is close to the inner top panel 02; a lamp space 31 is formed between the lamp holder 03 and the inner top panel 02; a purification space 13 is formed between the lamp holder 03 and the outer panel 01; smoke inlets 11 are respectively opened at opposite ends of the outer panel 01 and the smoke exhaust port 12; the smoke inlet 11 is connected to the purification space 13 through the smoke inlet pipe 08; the smoke exhaust port 12 is connected to the purification space 13 through the smoke exhaust pipe 09; the lamp guiding device 05 is located in the lamp guiding space 31; the lamp guiding device 05 is arranged on the lamp guiding seat 03 and is close to the smoke exhaust port 12; the ultraviolet lamp 61 is arranged in the lamp guiding space 31, and the ultraviolet lamp 61 is connected to the lamp guiding device 05; the exhaust device 04 is arranged in the purification space 13 and is close to the smoke exhaust port 12; the smoke baffle 100 is arranged in the purification space 13 and is close to the smoke inlet 11; the power connecting piece 07 is located in the lamp guiding space 31 and is arranged on the inner top plate 02.

[0041] The ultraviolet lamp is set on the inner side of the outer panel 01, which can prevent the ultraviolet lamp 61 from being exposed to the outside and causing ultraviolet light leakage, and long-term exposure to human health. A special oil fume purification channel is opened between the outer panel 01 and the inner top plate 02, and the lamp holder 03 is located therein. The ultraviolet lamp 61 is installed on the lamp holder 03. The ultraviolet lamp 61 can be moved by the lamp guide device 05 to increase or decrease the area irradiated by the ultraviolet lamp 61, which can purify the oil fume accordingly, thereby improving the energy utilization and purification efficiency to a certain extent. The smoke baffle 100 can buffer and absorb the incoming oil fume to a certain extent, avoiding the situation where the oil fume flow is too large and cannot be completely purified.

[0042] The following is a detailed introduction to each substructure:

[0043] The ultraviolet lamps 61 are arranged in sequence on the lamp holder and connected to each other to form an ultraviolet lamp group 06; the ultraviolet lamp group 06 is close to the lamp device 05 and connected to the lamp device 05 along the direction from the smoke inlet pipe 08 to the smoke exhaust pipe 09, and the other end extends to the position corresponding to the smoke inlet 11; the power connecting piece 07 is located in the lamp space 31, and the power connecting piece 07 corresponds to the purification space 13.

[0044] In this way, the ultraviolet lamps 61 are connected to each other to form an ultraviolet lamp group, and the lamp guiding device 05 controls the amount of ultraviolet light irradiated to the purification space 13, which can achieve efficient and energy-saving purification for oil smoke of different concentrations and flow rates, thereby improving the utilization rate of energy and fully realizing the purification of oil smoke.

[0045] It is understood that when a certain number of ultraviolet lamps 61 are needed to irradiate and purify cooking fumes, the lamp guide device 05 will drive the ultraviolet lamp group 06 to move closer to the lamp guide device 05, thereby causing a certain number of ultraviolet lamps 61 to enter the lamp guide space 31 corresponding to the purification space 13. At the same time, the ultraviolet lamps 61 located in the lamp guide space 31 corresponding to the purification space 13 will be connected to the power connection piece 07, and then powered on to irradiate with ultraviolet light, thereby achieving the effect of purifying cooking fumes.

[0046] It is worth noting that, on the one hand, the lamp guide device 05 can control the number of UV lamps 61 in operation. Furthermore, since the UV lamp assembly 06 is composed of multiple UV lamps 61, forming a modular product, the number of UV lamps 61 in the UV lamp assembly 06 can be set based on the actual kitchen space size, the amount of oil smoke, and customer needs. Furthermore, since the UV lamps 61 are not fixedly mounted on the lamp guide holder 03, replacement and maintenance of the UV lamps 61 are very convenient. The connection between the UV lamps 61 and the lamp guide holder 03 can be a sliding connection, a transmission connection, or other forms. In this embodiment, the connection between the UV lamps 61 and the lamp guide holder 03 is a sliding connection.

[0047] Even if ordinary ultraviolet lamp 61 is arranged on the lamp holder 03, it can only produce the effect of disinfection and cannot purify the oil smoke. In this embodiment, the ultraviolet light wavelengths emitted by ultraviolet lamp 61 are 185nm and 254nm.

[0048] The ultraviolet lamp 61 in this band produces ultraviolet rays and ozone, and further generates hydroxyl free radicals. The synergistic effect of these three factors (ultraviolet rays, ozone, and hydroxyl free radicals) completely decomposes the organic matter in the oil smoke into water and carbon dioxide. The purified air is discharged through the air outlet. Due to the action of the ultraviolet lamp 61, the air is also sterilized and disinfected at the same time.

[0049] Specifically, according to the third law of photochemistry, chemical bonds can only be broken when the energy of a photon is greater than or equal to the bond energy of the chemical bond in the molecule. The bond energy of the O〓O double bond in an oxygen molecule is 498 kJ / mol. According to the formula for calculating photon energy, the ultraviolet photon energy required to break the O〓O double bond in an oxygen molecule is at least the energy of ultraviolet light with a wavelength of 240 nm or less. Ultraviolet light with a wavelength of 185 nm has a wavelength shorter than 240 nm. Ultraviolet light of this wavelength can produce ozone when it acts on oxygen molecules, which in turn decomposes under the action of photons. This is a cyclical photochemical process.

[0050] When using UV lamp 61 to purify cooking fumes, high-energy ultraviolet radiation cleaves the chemical bonds of organic matter in the fume, forming free atoms or radicals. Furthermore, vacuum ultraviolet radiation (VUV) with a wavelength of 185 nm decomposes oxygen (O2) in the air, generating oxygen free radicals (O·). These oxygen free radicals combine with oxygen (O2) to produce ozone (O3), which, through its strong oxidizing properties, oxidizes organic matter. Ozone exhibits strong oxidizing properties because the oxygen atoms in ozone molecules are strongly electrophilic or protonic. The newly generated oxygen atoms from ozone decomposition react with water in a certain humidity environment to form hydroxyl radicals (·OH), which have even stronger oxidizing power. These highly active hydroxyl radicals can destroy the structure of organic matter, oxidizing and degrading cooking fumes into low-molecular substances, water, and carbon dioxide, thus achieving complete decomposition.

[0051] The lamp guiding device 05 has various forms and structures. In this embodiment, the lamp guiding device 05 includes a hydraulic actuator 51, a hydraulic source 52 and a controller 53; the piston rod of the hydraulic actuator 51 is connected to the ultraviolet lamp group 06; the hydraulic source 52 is connected to the hydraulic actuator 51; and the controller 53 is connected to the hydraulic source 52 and the exhaust device 04 at the same time.

[0052] Lamp guide device 05 uses a hydraulic actuator 51 to move UV lamp assembly 06. Controller 53 collects parameters and controls the movement of UV lamp 61 based on the operating conditions of exhaust device 04, achieving efficient and energy-saving fume purification. Furthermore, hydraulic actuator 51 provides stable movement, preventing violent shaking during movement, thus preventing poor contact between UV lamp assembly 06 and energized connector 07 or damage to UV lamp assembly 06.

[0053] The setting method of the smoke inlet pipe 08 also plays a certain role in the purification of oil smoke. In this embodiment, the diameter of the smoke inlet pipe 08 gradually increases from the end close to the smoke inlet 11 to the end close to the purification space 13; the end of the smoke inlet pipe 08 close to the purification space 13 is connected to the lamp holder 03 and the outer panel 01 at the same time to close the purification space 13.

[0054] The diameter of the smoke inlet pipe 08 is changed from small to large, which can further slow down the flow rate of oil smoke into the purification space 13, ensuring that the oil smoke can be fully purified in the purification space 13. At the same time, the diameter of the smoke inlet pipe 08 near the smoke inlet 11 is smaller, and the air intake volume is relatively small, which can also play a role in flow limiting to a certain extent.

[0055] In order to prevent the oil smoke from entering the purification space 13 too quickly and failing to complete the purification, a smoke shield 100 is set on the smoke inlet pipe 08 at one end of the pipe opening close to the purification space 13; the smoke shield 100 is spaced apart from the lamp holder 03; and the smoke shield 100 is spaced apart from the outer panel 01.

[0056] The smoke baffle 100 is located at the position of the smoke inlet pipe 08 close to the purification space 13. It can play a certain flow limiting role when the smoke intake is large. At the same time, it can also absorb and block part of the oil smoke, achieving a certain degree of oil control and purification effect.

[0057] Correspondingly, an oil trough 102 is embedded in the outer panel 01 at the location corresponding to the smoke deflector 100. A drainage column 101 is installed on the end of the smoke deflector 100 closest to the oil trough 102, with the end of the drainage column 101, further away from the smoke deflector 100, located within the oil trough 102. The oil trough 102 collects oil blocked by the smoke deflector 100, preventing it from dripping onto the outer panel 01 and potentially corroding it. The drainage column 101 guides the oil, preventing it from spilling onto the outer panel 01 and potentially affecting it.

[0058] Similarly, the structure of exhaust pipe 09 also has a certain impact on the purification of oil smoke. In this embodiment, the diameter of exhaust pipe 09 gradually decreases from the end near exhaust device 04 to the end near exhaust port 12; the exhaust direction of exhaust pipe 09 at exhaust port 12 is toward the side away from smoke inlet 11.

[0059] The diameter of the exhaust pipe 09 gradually decreases along the direction of airflow, which can increase the flow rate to a certain extent, allowing the purified air to be discharged quickly, avoiding accumulation in the exhaust pipe and preventing the purified air from flowing back. At the same time, due to the accelerated air flow, the purified air is discharged away from the smoke inlet 11, which can push the oil smoke in the exhaust area to other areas, forming a certain degree of spatial circulation and enhancing the purification effect.

[0060] The exhaust device 04 has various structures and forms. In this embodiment, the exhaust device 04 includes a guide plate 41 and an exhaust fan; the exhaust fan is connected to the lamp holder 03; the guide plate 41 is located in the purification space 13; the guide plate 41 is tilted, and one end is connected to the outer panel 01, and the other end is connected to the end of the exhaust fan away from the lamp holder 03.

[0061] The exhaust fan is connected to the lamp holder 03, isolating the lamp space 31 from the purification space 13. This prevents oil smoke from entering the lamp space 31 through the gap between the exhaust fan and the lamp holder 03, potentially affecting the lamp device 05 and the UV lamp 61. The guide plate 41 not only guides the purified air below the exhaust fan through the exhaust fan to be discharged, preventing stagnation and improving the purification effect, but also provides support and strengthens the structure of the outer panel 01.

[0062] It is also worth noting that, in the direction from smoke inlet pipe 08 to smoke exhaust pipe 09, the exhaust fan is closer to smoke exhaust pipe 09 than the lamp guide device 05. This provides the purification space 13 below the lamp guide device 05 with ample purification reaction space for the generated ozone and hydroxyl radicals, allowing for a better purification reaction and achieving efficient purification. This prevents the ozone and hydroxyl radicals formed by the ultraviolet light from being exhausted by the exhaust fan before they have time to undergo a purification reaction.

[0063] In summary, the ultraviolet lamp is arranged on the inner side of the outer panel 01, which can prevent the ultraviolet lamp 61 from being exposed to the outside and causing ultraviolet leakage, thereby eliminating the damage of ultraviolet rays to human health. A special oil fume purification channel is opened between the outer panel 01 and the inner top plate 02, in which the lamp holder 03 is located, and the ultraviolet lamp 61 is installed on the lamp holder 03 set in the channel. The ultraviolet lamp 61 is moved by the lamp guide device 05, thereby increasing or decreasing the area irradiated by the ultraviolet lamp 61, and the oil fume can be purified accordingly, which improves the energy utilization and purification efficiency to a certain extent. The smoke baffle 100 can buffer and absorb the incoming oil fume to a certain extent, avoiding the situation where the oil fume flow is too large and cannot be completely purified.

[0064] The ultraviolet lamps 61 are connected to each other to form an ultraviolet lamp group, and the lamp guide device 05 controls the amount of ultraviolet light irradiated to the purification space 13. It can achieve efficient and energy-saving purification for oil smoke of different concentrations and flow rates, which not only improves the utilization rate of energy, but also fully realizes the purification of oil smoke.

[0065] The ultraviolet lamp 61 in the 185nm and 254nm bands produces ultraviolet rays and ozone, and further generates hydroxyl free radicals. The synergistic effect of these three factors (ultraviolet rays, ozone, and hydroxyl free radicals) completely decomposes the organic matter in the smoke into water and carbon dioxide. The purified air is discharged through the air outlet. Due to the action of the ultraviolet lamp 61, the air is also sterilized and disinfected at the same time.

[0066] Lamp guide device 05 uses a hydraulic actuator 51 to move UV lamp assembly 06. Controller 53 collects parameters and controls the movement of UV lamp 61 based on the operating conditions of exhaust device 04, achieving efficient and energy-saving fume purification. Furthermore, hydraulic actuator 51 provides stable movement, preventing violent shaking during movement, thus preventing poor contact between UV lamp assembly 06 and energized connector 07 or damage to UV lamp assembly 06.

[0067] The diameter of the smoke inlet pipe 08 is changed from small to large, which can further slow down the flow rate of oil smoke into the purification space 13, ensuring that the oil smoke can be fully purified in the purification space 13. At the same time, the diameter of the smoke inlet pipe 08 near the smoke inlet 11 is smaller, and the air intake volume is relatively small, which can also play a role in flow limiting to a certain extent.

[0068] The smoke baffle 100 is located at the position of the smoke inlet pipe 08 close to the purification space 13. It can play a certain flow limiting role when the smoke intake is large. At the same time, it can also absorb and block part of the oil smoke, achieving a certain degree of oil control and purification effect.

[0069] The oil collecting groove 102 is used to collect the oil blocked by the smoke shield 100, preventing the oil on the smoke shield 100 from dripping onto the outer panel 01 and causing corrosion to the outer panel 01. The drainage column 101 can play a guiding role, preventing the oil dripping from the oil shield from splashing onto the outer panel 01 and affecting the outer panel 01.

[0070] The diameter of the exhaust pipe 09 gradually decreases along the direction of airflow, which can increase the flow rate to a certain extent, allowing the purified air to be discharged quickly, avoiding accumulation in the exhaust pipe and preventing the purified air from flowing back. At the same time, due to the accelerated air flow, the purified air is discharged away from the smoke inlet 11, which can push the oil smoke in the exhaust area to other areas, forming a certain degree of spatial circulation and enhancing the purification effect.

[0071] The exhaust fan is connected to the lamp holder 03, isolating the lamp space 31 from the purification space 13. This prevents oil smoke from entering the lamp space 31 through the gap between the exhaust fan and the lamp holder 03, potentially affecting the lamp device 05 and the UV lamp 61. The guide plate 41 not only guides the purified air below the exhaust fan through the exhaust fan to be discharged, preventing stagnation and improving the purification effect, but also provides support and strengthens the structure of the outer panel 01.

[0072] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
