[0021] Schematic diagram of a range hood that eliminates water vapor, reference Figures 1 to 9 According to a preferred embodiment of the present invention, a range hood for eliminating water vapor includes a housing 10, an oil filter plate 20, two heat-resistant water filters 30, an exhaust component 40 and an oil collecting box 50.
[0022] Specifically, if Figure 1 and Figure 2 As shown, the shell 10 has a lower chamber and an upper chamber 101; the oil filter plate 20 is tiltedly arranged in the lower chamber, and divides the lower chamber into a smoke collecting chamber 102 and an intermediate chamber 103, and the two ends of the intermediate chamber 103 are respectively connected to the upper chamber 101; the heat-resistant water filter 30 is arranged at the connection between the upper chamber 101 and the intermediate chamber 103; the exhaust component 40 is arranged between the two heat-resistant water filters 30, and the exhaust component 40 includes a fan 401 and a smoke exhaust channel 402, one end of the smoke exhaust channel 402 is connected to the air outlet of the fan 401, and the air inlet of the fan 401 is connected to the upper chamber 101; the oil collecting box 50 is connected to the shell 10, and the oil collecting box 50 is located at the lowest point of the intermediate chamber 103, and the first opening at the top of the oil collecting box 50 is connected to the intermediate chamber 103.
[0023] It should be noted that, when the oil fume flows into the smoke collecting chamber 102 and passes through the oil filter plate 20, most of the oil in the oil fume is filtered to the surface of the oil filter plate 20 by the oil filter plate 20, and the blocked oil flows along the inclined oil filter plate 20 to the oil collecting box 50; and after the smoke passes through the oil filter plate 20, when it passes through the heat-resistant water filter 30, the moisture in the smoke is filtered out, and the remaining gas flows from the fan 401 into the smoke exhaust channel 402 and is discharged.
[0024] Specifically, in order to achieve the barrier to moisture in the flue gas, refer to Figure 3 and Figure 5 The heat-resistant water filter 30 includes a side plate 301, absorbent paper 302 and an aluminum foil member 303. The absorbent paper 302 extends in a serpentine shape to form a plurality of first accommodating grooves 3021 and second accommodating grooves 3022. Each of the first accommodating grooves 3021 and the second accommodating grooves 3022 is provided with an aluminum foil member 303. The aluminum foil member 303 is bent in a wave-like manner. The heat-resistant water filter 30 is arranged horizontally, and the aluminum foil member 303 is arranged vertically.
[0025] It should be noted that the moisture in the smoke is blocked when passing through the bottom wall and side wall of the first receiving groove 3021 and the second receiving groove 3022. By extending the absorbent paper 302 in a serpentine shape, the overall surface area of the absorbent paper 302 is increased within a limited length, so as to block more moisture per unit time. In addition, by bending the aluminum foil 303 in a wave-like shape, the surface area of the aluminum foil 303 is increased. In addition, by making the aluminum foil 303 and the absorbent paper 302 extend in a serpentine shape, the surface area of the aluminum foil 303 is increased. When the aluminum foil 303 and the absorbent paper 302 are against each other, a guide channel is formed between the wavy aluminum foil 303 and the absorbent paper 302, thereby guiding the flow of the water-containing smoke. In addition, as the smoke moves toward the bottom of the first and second accommodating grooves 3021 and 3022, the temperature of the water-containing smoke gradually decreases, causing a portion of the water vapor to condense on the aluminum foil 303. Since the aluminum foil 303 is arranged vertically, the water molecules condense into water droplets and naturally slide down along the aluminum foil 303. It is obvious that compared with the prior art, the present application filters the oil in the smoke by providing the oil filter plate 20. By providing the heat-resistant water filter 30, the water vapor generated by the stove during "steaming" can be blocked by the heat-resistant water filter 30. Compared with the prior art that filters the oil in the smoke through an electric field and is not suitable for "steaming", the present application has the advantage of being able to eliminate water vapor for both steaming and frying.
[0026] Furthermore, in order to prevent the water droplets sliding downward from directly dripping onto the oil filter plate 20, the moisture content of the smoke passing through the oil filter plate 20 is increased, such as Figure 6As shown, the range hood for eliminating water vapor also includes a water guide member 60, which includes a snap-in end 601, two extended water guide rods 602 and a plurality of wave-shaped water guide strips 603. A wave-shaped water guide strip 603 is provided directly below each of the aluminum foil members 303, and the two ends of the wave-shaped water guide strip 603 are respectively connected to the two extended water guide rods 602. The extended water guide rod 602 has a first water guide groove 6021, and the wave-shaped water guide strip 603 has a second water guide groove 6031. The two ends of the second water guide groove 6031 are respectively connected to the two first water guide grooves 6021. The extended water guide rod 602 is arranged at an angle, and the lowest point of the extended water guide rod 602 is located directly above the oil collecting box 50.
[0027] It should be noted that, by providing the water guide member 60, when the water droplets slide down along the aluminum foil member 303, they will fall into the second water guide groove 6031 of the wave-shaped water guide strip 603, and because the second water guide groove 6031 is connected to the first water guide groove 6021, and the extended water guide rod 602 is arranged at an angle, the water droplets will eventually flow out from the end of the extended water guide rod 602 above the oil collecting box 50 after flowing from the second water guide groove 6031 into the first water guide groove 6021, that is, by providing the wave-shaped water guide strip 603 and the extended water guide rod 602, the water droplets not on the aluminum foil member 303 are collected, and the risk of the water droplets sliding vertically freely and re-humidifying the flue gas is effectively avoided; in addition, during installation, the water guide member 60 is fixed by inserting the embedded end 601 into the gap between the oil filter plate 20 and the outer shell 10.
[0028] Furthermore, if Figure 7 and Figure 8As shown, the range hood for eliminating water vapor further includes a water storage module 70 and a feeding module 80, and the water storage module 70 and the feeding module 80 are located between the water guide 60 and the oil collecting box 50 in the height direction, and the water storage module 70 includes a water storage box 701 and a heating element 702, the water storage box 701 has a water storage chamber 7011, and the top and bottom of the water storage chamber 7011 respectively have a second opening and a first water outlet 7012, and the heating element 702 is placed in the water storage chamber 7011, and the feeding module 80 includes a sliding member 801 and a material box 802, and the material box 802 is installed on the sliding member 801, and the sliding member 801 has a notch groove 8011, and the bottom of the notch groove 8011 has a second water outlet. Hole 8012, a first oblique wedge 7013 is provided at the mouth of the water storage chamber 7011, the discharge port of the material box 802 is located at the bottom of the material box 802, and the discharge port of the material box 802 is closed by a lifting member 8021, and the bottom of the lifting member 8021 has a second oblique wedge 8022. When the sliding member 801 slides, the first oblique wedge 7013 and the second oblique wedge 8022 contact or separate, and the discharge port of the material box 802 is opened or closed, and the second water outlet 8012 is opposite to the first water outlet 7012, or the second water outlet 8012 is staggered with the first water outlet 7012, and cleaning particles or cleaning fluid, such as detergent or sodium metasilicate, are provided in the material box 802.
[0029] In addition, if Figure 9 As shown, an oil collecting box 50 is provided directly below each of the heat-resistant water filters 30, and each of the oil collecting boxes 50 has an oil collecting chamber 501. One end of the oil collecting chamber 501 is provided with a liftable baffle 502, and the baffle 502 is lifted and lowered by a third linear drive device. The range hood for eliminating water vapor also includes two scrapers 901 and a second linear drive device 902. A scraper 901 is slidably provided in each of the oil collecting chambers 501, and the scraper 901 is slidable in the oil collecting chamber 501 by the corresponding second linear drive device 902. In addition, an external channel 503 connected to the kitchen drain pipe is provided between the two oil collecting boxes 50.
[0030] It should be noted that the water storage box 701 is located directly below the end of the two extended water guide rods 602 away from the embedded end 601. When water drops are discharged along the end of the first water guide groove 6021, they fall into the water storage cavity 7011 and are collected in the water storage cavity 7011. It should be noted that at this time, the second water outlet 8012 and the first water outlet 7012 are staggered in the height direction, so that the water in the water storage cavity 7011 will not be discharged from the first water outlet 7012. In addition, Figure 7As shown, the water storage module 70 further includes a first liquid level sensor 703, a temperature sensor 704 and a first linear drive device. The first linear drive device is mounted on the housing 10 and connected to the sliding member 801. When the push rod of the first linear drive device moves, the sliding member 801 moves. It should be noted that when the water contained in the water storage chamber 7011 reaches a specified height, the first liquid level sensor 703 receives a signal and activates the first linear drive device, causing the sliding member 801 to slide a predetermined distance toward the oil filter plate 20. When the sliding member 80 After sliding a predetermined distance, the second oblique wedge portion 8022 contacts the first oblique wedge portion 7013, and as the sliding member 801 slides further, the second oblique wedge portion 8022 moves upward by a predetermined distance, and the discharge port of the material box 802 is opened, so that the cleaning particles or cleaning fluid in the material box 802 falls downward and falls into the water storage box 701 located just below the material box 802, and mixes with the condensed water in the water storage box 701. In addition, a contact sensor is provided on the water storage box 701. When the sliding member 801 slides to the point where the second oblique wedge portion 8022 contacts the first oblique wedge portion 7013, the cleaning particles or cleaning fluid in the material box 802 falls downward and falls into the water storage box 701 located just below the material box 802, and mixes with the condensed water in the water storage box 701. In addition, a contact sensor is provided on the water storage box 701. When the first inclined wedge portion 7013 contacts, the contact sensor transmits a signal and the heating element 702 is energized, and the heating element 702 heats the solution in the water storage box 701, specifically, raising its temperature to 60°C. When the temperature sensor 704 detects that the solution temperature has risen to a specified position, the push rod of the first linear drive device is further extended. After the sliding member 801 slides a predetermined distance again, the second water outlet 8012 is opposite to the first water outlet 7012 in the height direction, and the solution passes through the first water outlet 7012 and the second water outlet 8012. 012, and falls into the oil collecting chamber 501 of the oil collecting box 50 below. At this time, the water level in the water storage chamber 7011 drops and sends an electrical signal, which enables the second linear drive device 902, and the scraper 901 slides in the oil collecting chamber 501. It should be noted that at this time, the cleaning solution with a higher temperature just falls into the oil collecting chamber 501 to dissolve the solidified oil. After the scraper 901 reciprocates a predetermined number of times, the third linear drive device is activated and causes the baffle 502 to move upward a predetermined distance, and the sewage flows into the external channel 503 and is finally discharged to the kitchen drain pipe. It is obvious that compared with the prior art, the present application makes full use of the condensed water in the water filtration process, and periodically cleans the oil collecting box 50 after collection to achieve self-cleaning, which can effectively delay the time of cleaning the oil collecting box 50. In addition, a second liquid level sensor 705 is provided at the bottom of the water storage chamber 7011. When the solution in the water storage chamber 7011 flows out, the second liquid level sensor 705 sends a signal, activates the first linear drive device, and resets the sliding member 801 to its initial position.
[0031] Furthermore, in order to avoid the sliding member 801 from resetting, Figure 8 As shown, the second oblique wedge portion 8022 interferes with the movement of the first oblique wedge portion 7013, the water storage chamber 7011 has a supporting column 706, the first oblique wedge portion 7013 is rotatably mounted on the supporting column 706, the end of the first oblique wedge portion 7013 close to the oil filter plate 20 is the first supporting plane 7014, and the end of the second oblique wedge portion 8022 away from the oil filter plate 20 is the second supporting plane 8023. When the sliding member 801 slides in the direction away from the oil filter plate 20 and makes the second supporting plane 8023 and the first supporting plane 7014 abut, the first oblique wedge portion 7013 rotates a predetermined angle. In addition, the water storage module 70 also includes a torsion spring, and the feeding module 80 also includes a spring. The torsion spring is provided at the rotational mounting position of the first oblique wedge portion 7013 and the abutment column 706, and the two ends of the spring are respectively connected to the second oblique wedge portion 8022 and the material box 802.
[0032] It should be noted that, during the resetting process of the sliding member 801, the second abutting plane 8023 abuts against the first abutting plane 7014. As the sliding member 801 slides further away from the oil filter plate 20, the first oblique wedge portion 7013 is forced to rotate by a predetermined angle to facilitate the passage of the second oblique wedge portion 8022. At the same time, this process does not cause the lifting member 8021 to move upward and open the discharge port of the material box 802. It should also be added that, by setting the spring, in the When the sliding member 801 slides toward the oil filter plate 20, after the second oblique wedge 8022 passes through the first oblique wedge 7013, the lifting member 8021 is reset under the action of the spring and closes the discharge port of the material box 802, thereby preventing excessive outflow of cleaning particles or cleaning fluid in the material box 802; in addition, during the resetting process of the sliding member 801, after the second oblique wedge 8022 passes through the first oblique wedge 7013, the first oblique wedge 7013 is reset under the action of the torsion spring.
[0033] In addition, in order to guide the condensed water to flow into the water storage box 701, Figure 7 As shown, the top of the material box 802 has a water diversion slope 8024.
[0034] In summary, the range hood for eliminating water vapor based on the embodiment of the present application is explained, which provides the range hood for eliminating water vapor with advantages such as dual-purpose for steaming and frying and the ability to eliminate water vapor.
