Description

Technical Field

[0001] The utility model relates to the field of oil fume separation and purification equipment, in particular to an environmentally friendly oil fume separation and purification range hood. Background Art

[0002] An environmentally friendly range hood with oil fume separation and purification is a kitchen appliance designed to reduce environmental pollution from cooking fumes. It improves air quality by separating and purifying cooking fumes. The filter and purification system within the appliance effectively remove grease and other harmful substances from cooking fumes, reducing pollution to the air and kitchen environment while also improving the appliance's energy efficiency.

[0003] After searching, a Chinese patent with the publication number CN220567326U discloses an environmentally friendly oil fume separation and purification range hood. The patent records that by starting a motor, the motor can drive the exhaust fan to rotate. The rotation of the exhaust fan will generate suction to discharge the sucked gas into the exhaust port, so that the oil fume generated during cooking will be sucked in. Due to the difference between oil and smoke in the oil fume, the smoke will pass through the smoke filter without any obstacles, but the oil carried by the smoke will be filtered out. The oil will slide along the inclined surface into the oil collection tank below. The oil collection tank is then taken out regularly through the chute. The sealing cover at the bottom is unscrewed to discharge the oil fume more conveniently.

[0004] In this solution, oil and impurities will adhere to the smoke filter net after a long time, causing the smoke filter net to be blocked, resulting in poor filtering effect in the later stage. When disassembling and assembling the device, the isolation plate and the smoke pipe must be removed first before the smoke filter net can be taken out. The process is time-consuming and labor-intensive, affecting work efficiency. In order to solve this technical problem, the utility model proposes an environmentally friendly oil fume separation and purification range hood. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] See also Figure 1-4 , the utility model provides a technical solution:

[0025] Example 1: An environmentally friendly oil fume separation and purification range hood, including an outer box 1, a smoke inlet pipe 5 is provided at the left end of the outer box 1, an air inlet fan 7 is fixedly connected to the inside of the smoke inlet pipe 5, an air outlet pipe 13 is provided at the right end of the outer box 1, an exhaust pipe 14 is fixedly connected to the inside of the air outlet pipe 13, a smoke filter 12 is fixedly connected to the inside of the outer box 1, and slides 17 are fixedly connected to both sides of the smoke filter 12. The upper and lower ends of the slides 17 on both sides are fixedly connected to fixed columns 22, and the other end of the fixed column 22 is fixedly connected to a spring 19. The other end of the spring 19 is fixedly connected to a connecting ball 20. A pair of slide grooves 15 are opened inside the outer box 1. At the same time, a pair of limiting holes 16 are opened inside the outer box 1 on both sides. At the same time, the slide 17 corresponds to the slide groove 15, and the connecting ball 20 corresponds to the limiting hole 16. The slide 17 is slidably connected in the slide groove 15, and the connecting ball 20 is slidably connected in the limiting hole 16. A handle 21 is fixedly connected to the top of the smoke filter 12, and a pair of sealing blocks 18 are fixedly connected to the top of the slides 17 on both sides.

[0026] During the long-term use of the smoke filter 12, the accumulated oil smoke and impurities may cause the smoke filter 12 to be blocked. In order to facilitate maintenance and cleaning, the system is designed with a convenient disassembly and installation mechanism for the smoke filter 12. The user can directly pull the handle 21 to take the smoke filter 12 out of the outer box 1. The design of the smoke filter 12 includes slides 17. These slides provide stable guidance in the slide groove 15 to ensure that the smoke filter 12 maintains the correct moving direction during the disassembly and installation process. After cleaning the smoke filter 12, when installing it again, the user only needs to align the slide 17 of the smoke filter 12 with the slide groove 15 and then slide it into the predetermined position. During the installation process, the connecting ball 20 will be compressed. Since the spring 19 behind it is in a compressed state, when the slide plate 17 slides to the bottom of the installation, the connecting ball 20 will move to the position of the limiting hole 16. At this time, the spring 19 pushes the connecting ball 20 out and accurately positions it in the limiting hole 16 through the rebound effect. This design not only ensures that the smoke filter 12 is firmly fixed in the outer box 1, but also prevents displacement problems during the installation process. At the same time, the sealing block 18 can tightly close the top gap of the outer box 1 after installation to prevent smoke leakage. The cooperation of this design enables the smoke filter 12 to be installed and disassembled quickly and efficiently, greatly improving the maintenance efficiency of the system and the convenience of the work process.

[0027] Embodiment 2: The difference between this embodiment and embodiment 1 is that, a water tank 2 is provided on the outside of the outer box 1, a water pump 3 is fixedly connected to the top of the water tank 2, a water pipe 4 is fixedly connected to the output end of the water pump 3, and the water pipe 4 passes through the water pump 3 and extends into the water tank 2, a connecting plate 8 is provided on the upper part of the inner part of the outer box 1, the other end of the water pipe 4 is fixedly connected to the connecting plate 8, and a number of nozzles 9 are provided on the bottom of the connecting plate 8, an inclined plate 11 is fixedly connected to the bottom end of the inner part of the outer box 1, and a water outlet 10 is opened at the bottom of the outer box 1, and the inclination angle of the inclined plate 11 corresponds to the water outlet 10, and a filter plate 6 is fixedly connected to the inside of the smoke inlet pipe 5.

[0028] Start the air inlet fan 7, so that the oil smoke is effectively sucked into the outer box 1 through the smoke inlet pipe 5. At the same time, start the water pump 3 on the top of the water tank 2. The water pump 3 draws out the water inside the water tank 2 and transports it to the nozzle 9 through the water pipe 4. The nozzle 9 sprays the water onto the oil smoke. This spraying action makes part of the oil in the oil smoke combine with the water and fall onto the inclined plate 11 with the water flow. On the inclined plate 11, the attached oil and water will continue to flow and be discharged from the system through the water outlet 10, thereby reducing the residual oil. At the same time, the residual oil is discharged through the exhaust pipe 1 3 and the internal exhaust pipe 14, the smoke is effectively blown out, and the smoke will pass through the smoke filter 12 before being discharged. This process captures and adsorbs oil through the filter 12, thereby further purifying the smoke. The function of the smoke filter 12 is to ensure the separation of oil and smoke, making the discharged gas cleaner. The entire system realizes the effective separation and treatment of oil smoke through the three steps of spraying, exhausting and filtering, significantly improves the air quality, and reduces the pollution of oil smoke to the environment and equipment, thereby achieving efficient oil smoke cleaning and treatment effects.

[0029] Working principle: when the staff needs to separate the oil smoke, first start the air inlet fan 7 to draw the oil smoke into the outer box 1 through the smoke inlet pipe 5, then start the water pump 3 on the top of the water tank 2, and under the action of the water pump 3, the water inside the water tank 2 is pumped out and transported to the nozzle 9 through the water pipe 4, and the oil smoke is sprayed through the nozzle 9. At this time, some oil adheres to the water and falls onto the inclined plate 11, and is discharged through the water outlet 10. At this time, the smoke is blown out through the exhaust pipe 14 inside the air outlet pipe 13, and the smoke is filtered through the smoke filter 12, so that the oil is adsorbed on the smoke filter 12, thereby achieving the separation effect. The smoke filter 12 will be blocked for a long time. At this time, the smoke filter 12 can be taken out by directly pulling up the handle 21. The smoke filter 12 can be removed by sliding The plate 17 is limited in the slide groove 15, thereby ensuring that the movement direction of the smoke filter 12 is consistent. The quick release of the smoke filter 12 is convenient for cleaning. After cleaning is completed, when installing, the slides 17 on both sides of the smoke filter 12 are directly aligned with the slide groove 15 and slide directly in. During the sliding process, the connecting ball 20 will be squeezed, causing the spring 19 to be in a compressed state. When the slide 17 slides to the bottom, the connecting ball 20 slides to the position of the limiting hole 16. At this time, the spring 19 will directly push the connecting ball 20 into the limiting hole 16 through the rebound type, thereby positioning the smoke filter 12 in the outer box 1. At the same time, the sealing block 18 can block the gap at the top of the outer box 1 to prevent smoke from being discharged. Through the cooperation between them, the effect of rapid installation and disassembly is achieved, which greatly improves work efficiency.
