Description

  The present invention relates to a forced exhaust device such as a range hood for forcibly exhausting oil smoke generated indoors, for example, in a kitchen or a food processing plant.

  Ventilation fans and range hoods are installed as local exhaust devices in places where cooking is performed, such as kitchens in the kitchen and restaurants, and steam, oily smoke, or various odors generated by heating food during cooking. The comfort of the work environment is maintained by forcibly exhausting the composite gas. However, when steam, oily smoke, or various complex odor gases generated during cooking adhere to the wall, the forced exhaust system itself is contaminated, and if the attached dirt is not removed, the ventilation performance deteriorates. Malfunctions such as odor generation and mold breeding occur, and the comfort of the work environment cannot be maintained. In order to maintain a comfortable working environment, it is necessary to remove contaminants adhering to the surfaces of the ventilation fan and the range hood, and perform maintenance to maintain ventilation performance and hygienic conditions. In particular, when oil smoke adheres and the wall surface is contaminated with oil, not only does it look dirty, but also the fatty acids and aldehydes that are components of the attached oil diffuse as malodorous substances, widely affecting not only kitchens but also living spaces. Therefore, countermeasures for adhering oil are a major issue.

  Normally, a filter made of glass fiber is installed in the vicinity of the inlet of a ventilation fan or range hood, and the generated oil smoke is adsorbed to prevent oil stains inside the vent. Oil that has not been absorbed by the filter is trapped by a ventilation fan or grease filter inside the range hood, and then dripped near the cooking area to collect oil such as an oil catch so as not to expand contamination. It is devised to be collected in the department. Then, replace the filter that has become soiled by adsorbing oil with a new filter, remove the oil attached to the grease filter by washing, and discard and wash the oil that has accumulated on the oil catch. Maintenance is performed.

  Thus, in order to use a ventilation fan or range hood for a long period of time, it is necessary to perform maintenance for oil decontamination, but the work of cleaning oil stains is cumbersome and tends to be avoided because of the work time. It happens that the oil is left without being removed by the cleaning operation. If the oil cleaning operation is neglected, the accumulated oil will be oxidized by reacting with oxygen in the air, and the oil will harden due to oxidation, and the cleaning operation will be complicated. A system that could be removed was eagerly desired. Therefore, in order to improve the maintainability of the ventilation fan and the range hood, a forced exhaust device that decomposes and removes oil has been devised (see, for example, Patent Document 1).

  Hereinafter, such a forced exhaust device will be described with reference to FIG.

As shown in FIG. 15, the range hood 101 has a hood case 102 with an inner surface coated with TiO 2, a fan 103 with a surface coated with TiO 2, a metal filter 104 with a surface coated with TiO 2, and a surface coated with TiO 2. A light source 105 is provided. When oil is attached to the inside using the range hood 101, the attached oil is efficiently decomposed by the photocatalytic action of TiO2 by irradiating UV light having a wavelength of 300 nm or more from the light source 105. This makes it easy to decompose and remove the attached oil without washing.

The part 15 is arranged. The lower surface of the cleaning liquid reservoir 15 is connected to the cleaning liquid waste tank 18 through the filtration membrane 16 and the lid 17.

  Further, the water supply channel 19 communicates with the cleaning liquid reservoir 15 to the outside, and the water supply channel 19 is provided with an opening / closing means 20. In addition, a liquid supply inlet 21 connected to the liquid supply pump 12 is communicated with the cleaning liquid reservoir 15. The oil collecting means 5 is connected to an oil detecting means 22, an antioxidant means 23 and a vibration generating means 24. The switching lid 6, the air blowing means 8, the liquid feed pump 12, the lid portion 17, the opening / closing means 20, the oil detection means 22, the antioxidant means 23, and the vibration generating means 24 are connected to the control means 25 by wiring.

  Any vibration generating means may be used as long as vibration can be generated, and examples thereof include a piezoelectric element. The oil detection means only needs to detect the collected oil, and includes, for example, a weight sensor. Antioxidation means 23 only needs to be able to prevent oil from being oxidized. For example, electrostatic reduction method, high-frequency hydrogen atom generation method, oxidation prevention by generating negative ions using a semiconductor, or titanium oxide, There is an oxidation prevention using a reduced ion from a ceramic carrier. The oil collecting means 5 only needs to be able to collect oil, and includes, for example, a filter, preferably nonflammable, and includes a glass fiber filter, a metal filter, a honeycomb filter formed of diatomaceous earth, and the like. As the air blowing means 8, it is sufficient if air can be blown, and for example, there is a sirocco fan. The opening / closing means 20 may be an opening / closing means such as an electromagnetic valve.

  The material of the collection hood 1, the front duct 4 and the rear duct 7 is preferably a hard material such as metal or plastic, and any material that does not exhibit plasticity against the heat generated during cooking should be used.

As shown in FIG. 1B, the air blowing means 8 includes a sirocco fan 26 and a motor 27.

  In the above configuration, the switching lid 6 is opened, the front duct 4 and the rear duct 7 are communicated, and the motor 27 is rotated to drive the sirocco fan 26, whereby air is sent from the suction port 3 to the discharge port 11, Oil smoke generated near the suction port 3 is sucked into the front duct 4 together with air. The sucked oil smoke is collected by adhering to the oil collecting means 5, and the air, from which the oil smoke has been removed and purified, passes through the rear duct 7 and is discharged from the discharge port 11 to the outdoors 10.

  When the oil detection means 22 detects that oil has been collected in the oil collection means 5, the control means 25 controls the antioxidant means 23 and the oil decomposition means to drive. A method for decomposing and washing the oil collected by the oil collecting means 5 by the oil decomposing means will be described with reference to FIG.

  In FIG. 1 (c), the oil decomposing means includes a liquid feed pump 12, a liquid feed pipe opening 14, and a cleaning liquid reservoir 15, and an enzyme holding means 28 is provided inside the cleaning liquid reservoir 15. Water can be supplied from the water supply channel 19 into the cleaning liquid reservoir 15 in advance to prepare for oil decomposition. Both the water in the cleaning liquid reservoir 15 and the enzyme holding means 28 are sucked from the liquid feeding inlet 21 by the liquid feeding pump 12, pass through the liquid feeding pipe 13, and discharged from the liquid feeding pipe opening 14. The discharged water and the oil-degrading enzyme such as lipase held in the enzyme holding means 28 such as activated carbon, zeolite, or silicon earth fall while contacting the surface of the oil collecting means 5, and again enter the cleaning liquid reservoir 15. At the same time, the oil is removed from the oil collecting means 5 such as a filter and collected in the cleaning liquid reservoir 15.

  The oil recovered in the cleaning liquid reservoir 15 is decomposed by an oil-degrading enzyme such as lipase held in enzyme holding means 28 such as activated carbon or zeolite, and the mixture of the decomposed oil and water passes through the filtration membrane 16. Then, it is discharged to the cleaning liquid disposal tank 18. In addition, only water is discharged from the liquid feed pipe opening 14 onto the surface of the oil collecting means 5 such as a filter, the oil is removed from the oil collecting means 5 by washing with water, and activated carbon or zeolite is washed in the washing liquid reservoir 15. Alternatively, it can be decomposed by reacting an oil-degrading enzyme such as lipase retained in the enzyme retaining means 28 such as diatomaceous earth with the removed oil.

  Examples of the enzyme holding means include carriers such as silica gel and ion exchange resin on which an oil-degrading enzyme such as lipase is adsorbed and fixed.

  The control means 25 controls a series of operations of the oil decomposition means. This operation will be described with reference to the operation flowchart of FIG.

  After the operation of the blowing means 8 is started by a switch operation or a timer (S1), the switching lid is opened (S2), and indoor oil smoke is sucked from the suction port 3. Then, the air blowing means 8 is again stopped by a switch operation or a timer (S3), and the switching lid is closed (S4). Next, the oil detection means 22 such as a weight sensor detects the amount of oil collected by the oil collection means 5 such as a filter (S5), and the detected amount of oil serves as a reference for starting cleaning. If it is less than G1 and greater than the amount of oil G2, which is the operating reference for the antioxidant means 23, then the antioxidant means 23 continues to operate until the blower means 8 such as a sirocco fan is operated (S6).

  By operating the oxidation preventing means 23 such as an electrostatic reduction method, the oil collected in the oil collecting means 5 can be prevented from being oxidized, and the oil can be stored in a dry state for a long period of time. Therefore, the oil can be easily removed and washed without having to wash the oil every time it is collected, and the oil washing efficiency is improved, so the number of times of oil washing is also reduced. Therefore, the cost of oil cleaning is reduced. Also, the bad odor caused by the oxidation of oil is not generated, so that the indoor environment can be kept comfortable.

  If the amount of oil detected by the oil detection means 22 such as a weight sensor is less than G2, the system waits until the next time the air blowing means 8 such as a blower is operated (S7).

  When the detected amount of oil is larger than G1, the opening / closing means 20 such as a solenoid valve is opened to supply water into the cleaning liquid reservoir 15 (S8), and the opening / closing means 20 is closed after a preset time (S9). ). For example, it is possible to supply water into the cleaning liquid reservoir 15 by connecting the water supply channel 19 to the water supply in advance and opening the closing means 20 for a preset 1 to 5 minutes. As long as the time can be secured within 15, the time is not limited.

  Next, the liquid feeding pump 12 is driven, and the water in the cleaning liquid reservoir 15 and the enzyme holding means 28 are discharged from the liquid feeding pipe opening 14 (S10). Next, by operating the vibration generating means 24 (S11), the oil collecting means 5 such as a filter directly vibrates with the enzyme holding means 28 such as activated carbon or zeolite while vibrating, that is, the lipase held by the enzyme holding means 28, etc. The oil comes into direct contact with the oil-degrading enzyme and frees the attached oil. When the enzyme holding means 28 having oil decomposition activity directly collides with the vibrating oil collecting means 5 in this way, the energy of re-collision increases, and as a result, energy is expended in peeling off the attached oil. As a result, it becomes easy to release the adhered oil, so that the cleaning time is shortened and the cost is reduced.

  The liberated oil is collected in the cleaning liquid reservoir 15 and decomposed by an oil-degrading enzyme such as lipase held in the enzyme holding means 28. After operating for a predetermined time, the operation of the liquid feeding pump 12 is stopped (S12), the cleaning is stopped, and the switching lid 6 is opened (S13).

  For example, in order to decompose 1 to 3 g of oil collected by one cooking in a general household with an oil-degrading enzyme such as lipase, 3.4 to 10.2 millimoles of oil decomposing activity is required. When using 10 g of an oil-degrading enzyme such as lipase having a unit (micromol / min) / g oil-decomposing activity, all the collected oil is decomposed by operating the oil-decomposing means for 6 to 20 hours. Will be able to.

  Moreover, the time required for oil decomposition can be set in advance according to the oil-decomposing activity and the amount of oil-degrading enzyme such as lipase held in enzyme holding means 28 such as activated carbon or zeolite, and all oils can be decomposed. If it is time, it can be set as a predetermined time. After opening the switching lid 6, the operation of the blowing means 8 is started (S14), and the water adhering to the oil collecting means is completely removed. At this time, by operating the air blowing unit 8 while the vibration holding unit 24 is operated, moisture attached to the oil collecting unit can be quickly removed, so that the drying time is shortened and the cost is reduced. After operating for a predetermined time, the operation of the air blowing means 8 is stopped (S15), the switching lid 6 is closed (S16), and the drying of the oil collecting means is finished. Then, after stopping the vibration generating means 24 (S17), the lid 17 is opened (S18), and water and oil decomposition products in the cleaning liquid reservoir 15 are drained to the cleaning liquid waste tank 18. Finally, the lid 17 is closed (S19), and the operation of the oil decomposing means is terminated by stopping the oxidation preventing means (S20).

  The switching lid 6 is an openable and closable lid that blocks the communication between the front duct 4 and the rear duct 7 and prevents the cleaning liquid from leaking into the rear duct 7. The air blowing means 8 includes, for example, a motor 27 and a sirocco fan 26. Any means can be used as long as it can generate static pressure and discharge indoor air outdoors. It doesn't matter.

  The liquid feed pump 12 may be a small tube pump or a piston pump, for example. Further, as the liquid feeding tube 13, for example, a tube made of silicon or rubber can be used. Further, the liquid supply pipe opening 14 is, for example, a portion opened in a rubber tube that is the liquid supply pipe 13, and a distributed shower structure can be used to discharge the cleaning liquid to the oil collecting means 5 without unevenness. . The cleaning liquid reservoir 15 is, for example, a resin container having a drain hole opened in the lower portion, and communicates with the front duct 4. Further, the filtration membrane 16 can use, for example, a mesh formed of stainless steel or synthetic resin, and the decomposition product of water and oil used for washing can be obtained while the enzyme holding means 28 is held in the washing liquid reservoir 15. It can be discarded in the cleaning liquid disposal tank 18.

The cleaning cost can be reduced. The lid 17 is for holding the cleaning liquid in the cleaning liquid reservoir 15 by covering the filtration membrane 16, and for example, an openable / closable lid or an electromagnetic valve can be used. The cleaning liquid disposal tank 18 can hold an aqueous solution such as a plastic tank and can be larger than the volume in the cleaning liquid reservoir 15, but can be used as a wastewater treatment facility such as a sewerage facility or a combined septic tank. You can also connect to.

  The water supply channel 19 can be made of, for example, a tube made of silicon, rubber, or metal. Moreover, the opening / closing means 20 can use a solenoid valve, for example. Further, the liquid feeding inlet 21 can be a tube made of silicon, rubber or metal.

  Further, the oil detection means 22 uses, for example, a weight sensor, stores an initial weight value to which the collected oil is not attached, and subtracts the initial weight value from the weight value after the oil collection, thereby reducing the attached oil amount. Can be calculated as a value. Further, for example, by using an electrostatic capacity detection device, an electrode whose surface is electrically insulated is installed on the oil collecting means 5, and a change in the electrostatic capacity on the oil collecting means 5 is detected. The collected oil can be detected. Further, for example, an orguster type oil sensor can be used. When the oil comes into contact with the polymer film in which the carbon conductive fine particles are dispersed and the polymer film swells, the contact resistance between the conductive fine particles increases, and the oil can be detected instantaneously.

  Further, as the oxidation preventing means 23, for example, an electrostatic reduction type oxidation prevention device, a high frequency type hydrogen atom generation type oxidation prevention device, or a device that prevents oxidation by generating negative ions using a semiconductor. However, it is also possible to prevent oxidation by using reduced ions from titanium oxide or a ceramic carrier. The control means 25 can use, for example, a microcomputer having the operation flow program of FIG. The enzyme holding means 28 is a carrier such as silica gel or ion exchange resin on which lipase, which is an oil-degrading enzyme, is adsorbed and fixed, for example, and can remain in the cleaning liquid reservoir 15 without passing through the filtration membrane 16. You can use the same thing. Further, the size of the enzyme holding means 28 can be changed by changing the mesh of the filtration membrane 16.

  The enzyme holding means 28 can also be obtained by adsorbing and fixing lipase, which is an oil-degrading enzyme, to ion exchange resin, activated carbon, zeolite, diatomaceous earth, or silica gel, for example. For example, a high yield of lipase can be obtained by adsorbing and fixing a lipase produced by a strain belonging to either Candida rugosa or Pseudomonas cepacia to a hydrophobic carrier with a wide selectivity to oil. A carrier adsorbed with can be obtained. By using these types of lipases, enzyme holding means 28 having high oil decomposing activity can be obtained regardless of the type of oil collected. In addition, a lipase-immobilized carrier that is easily compatible with oil can be obtained by preliminarily adsorbing and fixing the lipase to a hydrophobic carrier. For example, high oil It becomes the enzyme holding means 28 having a decomposition activity.

A forced exhaust device that can be removed and cleaned is obtained. In addition, since the cleaning efficiency is improved, the time and cost spent for cleaning can be reduced. Moreover, since the oil is decomposed using an enzyme for oil washing, the oil can be efficiently decomposed and the environmental load can be reduced. Further, it is possible to reduce the troublesomeness of the oil cleaning work for a person who uses the forced exhaust device.
