  The present invention relates to a garbage processing apparatus or a set-free garbage processing apparatus that is mainly built in a household sink, and in particular, a garbage that can be input into a garbage processing chamber below from an input port. The present invention relates to a waste disposal apparatus.

  Conventionally, this kind of garbage processing apparatus is built in the sink unit, and a stirring blade is provided in the garbage processing tank of this garbage processing apparatus. The garbage treatment tank is filled with a garbage treatment material, and the garbage is decomposed by the action of microorganisms such as bacteria that inhabit the garbage treatment material. The sink top plate, which is the upper surface of the sink, is provided with an input port for garbage input, and an openable / closable lid is provided at the input port. The inlet and the garbage treatment tank are connected by a duct.

  In addition, an outdoor exhaust port is provided outside the outdoor wall of the building, and the outdoor exhaust port and the garbage disposal tank communicate with each other through an exhaust path. In the middle of the exhaust path, a blower fan for exhaust and a catalyst heating type deodorizer are arranged. When opening the lid and throwing in garbage from the inlet, in order to prevent odors from flowing back into the kitchen through the duct and inlet, increase the air volume of the blower fan when opening the inlet, The flow rate is increased by increasing the air volume to be sucked so that the odor does not flow backward (see, for example, Patent Document 1).

  Further, in other conventional garbage processing apparatuses, a deodorizing means for adsorbing and deodorizing the odors in the cracked gas is provided in the exhaust system, and the heating and regeneration operation of the deodorizing means by the heating means is excluded except during a period when decomposition is active. Therefore, it is performed when there is little odor generation (for example, see Patent Document 2).

JP 2002-66500 A Japanese Patent Laid-Open No. 9-47744

  However, in the configuration of the conventional garbage processing apparatus, when the blower fan is driven, outside air is sucked in through the air suction port of the overflow container of the garbage processing tank, and fresh air is sent to the garbage processing tank, It is deodorized by the deodorizer and discharged to the outside. In the deodorizer, the deodorized exhaust gas is mixed with the air from the air suction port, diluted, and discharged to the outside. The configuration communicated with the outside, for example, the kitchen, and had a problem that the odor generated from the garbage treatment tank could not be reliably blocked.

  In addition, the catalyst heating type deodorizer has a problem that it is necessary to heat and maintain the catalyst at a temperature of 300 ° C. or higher, and the running cost increases.

  In addition, when the deodorizing means for adsorbing and deodorizing is heated and regenerated, it has a problem that it is performed at night when the odor does not cause unpleasant feeling to the user, or it is decomposed and deodorized by a separate oxidation catalyst or the like. It was.

The present invention solves the above-described conventional problems, and sucks garbage so that odor does not leak into the room when the garbage is introduced from the garbage inlet, and the sucked odor is externally converted into odor through a deodorizing material. It is an object of the present invention to provide a garbage disposal apparatus capable of performing a regeneration operation for maintaining the deodorizing performance of the deodorizing material at low cost.

  In order to solve the above-described conventional problems, a garbage disposal apparatus according to the present invention includes a garbage input port for inputting garbage, and a food waste reducing process that is provided below the garbage input port. A waste treatment chamber, an intake duct provided around the garbage input port and communicating with the garbage input port at least when the garbage is input, a suction unit communicating with the intake duct, the suction unit and the intake unit A deodorizing material provided between the ducts, and in order to regenerate the deodorizing material, air different from the air in the garbage processing chamber is allowed to flow through the deodorizing material, and the garbage is thrown in. At this time, odor is sucked from the intake duct provided around the garbage input port, and this odor is adsorbed by the deodorizing material, so that the odor of the garbage does not flow out from the garbage processing chamber. In addition, the deodorizing material can be efficiently regenerated and the deodorizing performance can be maintained by flowing air different from odor-rich air in the garbage disposal chamber to the deodorizing material. Moreover, since the electric power for heating is unnecessary for the reproduction | regeneration operation | movement of a deodorizing material, the raise of a running cost can also be prevented.

  The garbage disposal apparatus of the present invention can prevent odor from being generated in the room when the garbage is introduced into the garbage treatment chamber from the garbage input port, and can maintain the deodorizing performance by the regenerating operation. . Further, the regeneration operation of the deodorizing material can prevent an increase in running cost because no heating power is required.

In addition, the deodorizing material can be efficiently regenerated and the deodorizing performance can be maintained by flowing air different from odor-rich air in the garbage disposal chamber to the deodorizing material. Moreover, since the electric power for heating is unnecessary for the reproduction | regeneration operation | movement of a deodorizing material, the raise of a running cost can also be prevented.

In the second invention, in particular, the deodorizing material of the first invention is a hybrid deodorizing material, and the regeneration operation performed to maintain the adsorption and deodorizing performance of the deodorizing material is performed by removing the odor component adsorbed from the deodorizing material. Since it is gradually desorbed, it is possible to create a state where the operator cannot recognize it as an odor. In addition, since the regeneration operation of the deodorizing material does not require heating power, an increase in running cost can be prevented. Moreover, the state which a user cannot recognize as an odor can be made by the reproduction | regeneration operation | movement which removes | desorbs the odor component adsorbed from a deodorizing material gradually with the fresh air which does not contain an odor.

  In particular, the third invention is provided with a condensing deodorization device that communicates with the garbage processing chamber via a circulation path separately from the deodorizing material of the first or second invention, and the condensation deodorizing is performed during the garbage reduction process. The device is designed to deodorize, and since a large amount of water vapor and odor generated from the garbage during the drying process are removed by the condensation deodorizer, the odor components adsorbed by the deodorizer when the garbage is put in should be reduced. Thus, the regeneration time of the deodorizing material can be shortened.

  In the fourth invention, in particular, the deodorizing material according to any one of the first to third inventions is arranged upstream of the suction means so that all of the air sucked by the suction means passes through the deodorizing material.

  In particular, the sixth invention is provided with a suction hose that communicates the intake duct of any one of the first to fifth inventions with the deodorizing material, and the air for regenerating the deodorizing material is branched to the suction hose. The fresh air is supplied from the introduction passage while one suction means is fixed, and the regeneration operation can be performed efficiently.

  In particular, the seventh invention is provided with a passage switching damper for switching between the suction hose and the introduction passage of the sixth invention. The introduction passage can be easily opened and the suction hose is closed to close the suction hose side. Can be sealed to isolate the odorous air in the air intake duct from fresh outside air, so that the regeneration operation can be performed efficiently.

  In the eighth invention, in particular, the deodorizing material is regenerated by introducing the air in the sink in which the garbage processing apparatus according to any one of the first to seventh inventions is installed. Various odors accumulated inside the sink, not the air containing the odor generated from the drying process, are adsorbed by the deodorizing material, and since the concentration is very small, it can be removed while adsorbing. Odor can be reduced when the door is opened.

Reference numeral 2 denotes a sink of the sink 1 having a drain port 3 into which raw garbage or water (tap water or the like) is introduced or mixed. Usually, such a drain outlet 3 is provided with a strainer (such as a garbage basket). Reference numeral 4 denotes a garbage input port for garbage input provided on the top plate 5 at the upper end of the sink 2.

  The top plate 5 is molded integrally with the sink 2 from a material such as stainless steel (some of which may be resin), and when the drain port 3 is clogged with clogging, the water from the faucet 6 becomes the upper end of the top plate 5. Can be stored up to.

  The garbage input port 4 is provided with an input port lid 7. The inlet cover 7 is configured to be substantially flush with the upper end of the top plate 5 when closed. Since the arrangement of the garbage input port 4 with respect to the sink 2 is configured on the right side toward the sink 2, the sink 2 has a shape in which the molding of the portion protrudes.

  A cylindrical charging passage 8 is provided below the garbage charging port 4. A garbage processing chamber 9 for drying and reducing the input garbage 10 is provided below the input passage 8. The input passage 8 and the garbage processing chamber 9 are resin-molded and configured as an integral container. The input passage 8 and the garbage processing chamber 9 are configured in a sealed container using the input port lid 7 so that the vapor and odor of the input garbage 10 do not leak to the outside. The resin material of the input passage 8 and the garbage processing chamber 9 is molded from a heat-resistant resin that can withstand the drying temperature (for example, 70 to 100 ° C.) of the input garbage 10.

  The garbage disposal chamber 9 is disposed below the bottom 11 of the sink 2, and the shape thereof is formed in a substantially semi-ellipsoidal cross-section in which the upper part is substantially flat and the lower part is curved. The passage 8 is connected. The garbage disposal chamber 9 is provided with an opening 12 in the direction in which the user faces the sink 2 (the side on which the housework work is performed in front of the sink). From the opening 12, the garbage container 13 is accommodated in the garbage processing chamber 9 like a drawer so as to fit the curved shape of the garbage processing chamber 9.

  The garbage container 13 is formed of a heat-resistant resin that can withstand the drying temperature (for example, 70 to 100 ° C.) of the input garbage 10, similarly to the resin material of the garbage processing chamber 9. The inner surface is coated to prevent the collected garbage 16 from sticking. The garbage agitation means 14 for agitating the input garbage 10 in the garbage container 13 is configured around a drive shaft 15 provided in the garbage container 13. The drive shaft 15 in the garbage container 13 collects the collected garbage 16 (the input garbage 10 and the dried garbage, etc.) in the garbage container 13 and disposes the garbage container 13 in the garbage processing chamber 9 when it is discarded. It is configured to be detachable from the drive shaft 18 of the drive means 17 of the garbage agitation means 14 so that the work can be easily performed when being drawn out.

  The drive means 17 is coupled to the drive shaft 15 via the drive shaft 18 from the outside of the garbage processing chamber 9. The drive means 17 is comprised with the geared motor. The garbage agitation means 14 agitates the collected garbage 16 while repeating normal rotation and inversion at 5 to 20 revolutions per minute while providing a stop time at regular intervals by this geared motor.

  When the garbage container 13 is stored in the garbage processing chamber 9, the drive shaft 18 and the drive shaft 15 come into contact with each other so that rotation can be transmitted. The drive shaft 18 is attached to the garbage processing chamber 9 by using a bearing portion 19 composed of a bearing and a mechanical seal to improve the sealing performance. Further, the sealing performance is enhanced with respect to the drive shaft 15 in the garbage container 13 by using a bearing portion 20 constituted by a bearing and a mechanical seal. The bearing portion 20 is also provided on the side wall of the garbage container 13 on the side opposite to the driving means 17 and supports the rotation of the driving shaft 15.

  The garbage container 13 is configured to have a substantially semi-circular circular cross-sectional shape in accordance with the garbage processing chamber 9 having a substantially semi-elliptical cross-sectional shape, and is larger than the substantially semi-elliptical cross-section of the garbage processing chamber 9 on the near side of drawing. An outer front plate 21 is provided, and the front plate 21 is pressed against the wall surface of the garbage processing chamber 9 with a lever or the like (not shown) through a packing 22 (sealing material or the like) so as to improve the sealing performance. .

The upper part of the garbage container 13 is opened like a drawer, and receives and stores the input garbage 10 introduced from the garbage input port 4 through the input passage 8. The garbage agitation means 14 is composed of a plurality of rods or spatula-like plates, and the tip of the garbage agitation means 14 rotates along the substantially semicircular inner wall of the garbage container 13 to agitate the collected garbage 16. I have to. The operation of the stirring means 14 is continuously performed with a fixed stop time, and the collected garbage 16 is stirred while repeating normal rotation and inversion.

  In the present embodiment, the front plate 21 of the garbage container 13 is inserted into the front plate (decorative plate) 23 of the sink 1 from above, and the garbage container 13 is pulled out from the garbage processing chamber 9 and collected. When discarding the garbage 16, the front plate 23 of the sink 1 is pulled out from the front plate 23 of the sink 1 using a rail structure (not shown) like a drawer (not shown) provided in the sink 1. The garbage container 13 can be taken out freely. 24 is a heating means provided in the lower part of the garbage processing chamber 9 to raise the temperature inside the garbage processing chamber 9, and performs a certain temperature adjustment using a general sheathed heater or mica heater, or a plate The PTC heater is used for automatic adjustment (the plate-like PTC can be attached to an aluminum or copper plate having good thermal conductivity and heated uniformly).

  The recovered garbage 16 is heated by the heating means 24 and the recovered garbage 16 is inverted by the garbage agitating means 14 to promote the drying process. Reference numeral 25 denotes air supply means for sending air 26 into the garbage processing chamber 9, and is composed of an air pump or a high-pressure blower such as a turbo fan or radial fan. The air supply means 25 ejects air 26 into the garbage processing chamber 9.

  Reference numeral 27 denotes a condensing deodorization device, which is configured by using bubble generating means in the liquid described later in order to reduce water vapor and odor generated when the collected garbage 16 is dried. A hermetic circulation path 28 is formed between the condensing deodorization device 27 and the garbage processing chamber 9, and air 26 is circulated by the air supply means 25 therebetween.

  In the garbage processing chamber 9, an exhaust port 29, which sucks water vapor in the garbage processing chamber 9 so as to be pushed out by the air 26 supplied by the air supply means 25, is provided at the upper portion of the garbage processing chamber 9. 30 to the condensation deodorization device 27 via the return pipe 31 of the circulation path 28. The return pipe 31 constitutes a circulation path 28 from the exhaust port 30 of the garbage processing chamber 9 to the inlet of the condensation deodorizing device 27.

  In the condensation and deodorization device 27, the water 33 stored in the liquid tank 32 of the condensation and deodorization device 27 (the water 33 includes water obtained by condensing tap water and water vapor of the input garbage 10) at the tip of the return pipe 31. A nozzle 34 is provided for ejecting the exhaust 29 as bubbles. The nozzle 34 is provided with a large number of fine holes (not shown) in order to create fine bubbles. By passing the bubbles of the exhaust gas 29 through the water 33, a large amount of water vapor contained in the exhaust gas 29 having a high temperature is cooled by the water 33, condensed and contained in the water 33, and removed. It becomes a small air 26. Further, the odor contained in the exhaust gas 29 (for example, main bad odors generated when the input garbage 10 is dried include hydrogen sulfide, trimethylamine, methyl mercaptan, aldehydes, etc.) are often water-soluble. Therefore, the air 26 is absorbed in the water 33 and deodorized.

  A space 35 having a constant volume is provided above the liquid tank 32, and the water 33 and the air 26 are separated by the space 35. In order to manage the amount of water 33 in the liquid tank 32 or the volume of the space 35, a water level detection unit 36 that detects the water level of the stored water 33 is provided in the liquid tank 32. The water level detection unit 36 is configured by a liquid level detection switch (not shown) such as a float type or an electrode type.

A suction inlet 38 of the outgoing pipe 37 of the circulation path 28 is provided in the upper part of the space 35 of the liquid tank 32. The leading end of the outgoing pipe 37 is opened as an air supply port 39 in the garbage processing chamber 9. The outgoing pipe 37 constitutes a circulation path 28 from the outlet of the condensation deodorizing device 27 to the intake port 39 of the garbage processing chamber 9. An air supply means 25 is provided in the middle of the outgoing pipe 37 so as to suck the air 26 having a lowered temperature from the suction inlet 38. An upper heating means 40 is provided in the middle of the outgoing pipe 37 between the air supply means 25 and the air supply port 39. The upper heating means 40 performs a certain temperature adjustment using a general sheathed heater or a mica heater, or performs an automatic adjustment using a PTC heater. As a result, the air 26 supplied from the air supply port 39 is heated and formed as dry air 26 having a reduced relative humidity, and it becomes easy to collect water vapor from the input garbage 10.

  The air supply port 39 is opened in the rear surface 41 on the driving means 17 side of the garbage processing chamber 9, and the tip thereof is disposed through the notch 43 on the side surface 42 on the driving means 17 side of the garbage container 13. It is provided to protrude downward so that the heated air 26 is directed downward.

  In the condensing deodorization device 27, in order to condense and condense the water vapor generated from the input garbage 10 in the garbage processing chamber 9, the difference from the drying temperature (for example, 70 to 100 ° C.) of the garbage processing chamber 9 is maintained. Thus, new water 33 is periodically injected into the liquid tank 32 from the water supply path 44. The new water 33 has dropped to the water temperature at that time. A water temperature detector 45 is provided in the liquid tank 32 in order to inject the new water 33. The water temperature detection unit 45 is composed of a thermocouple or a thermistor, and the temperature of the water 33 in the liquid tank 32 rises due to the water vapor from the input garbage 10, and the condensation capacity (for example, If the temperature of new water starts from 20 ° C. and rises to about 60 ° C., the temperature at which the condensing capacity is reduced by half) is detected.

  The configuration for replacing the water 33 in the liquid tank 32 of the condensing and deodorizing device 27 includes a water supply path 44 provided in the upper part of the liquid tank 32 and a drainage path 46 provided in the lower part of the liquid tank 32. Based on the signal from the water temperature detection unit 45, the controller 47 instructs to replace the water 33. The tip of the drainage channel 46 communicates with a drainage pipe 48 connected to the drainage port 3 of the sink 2, and a trap 49 is provided just before the drainage pipe 48 is connected to prevent bad odors and pests from entering the drainage pipe 48. I try to prevent it.

  A drain valve 50 and a drain check valve 51 are connected to the drain path 46 from the liquid tank 32 side. The drainage check valve 51 prevents the sewage from entering the liquid tank 32 and the drainage valve 50 even if a part of the water distribution pipe 48 is clogged and the sewage rises and flows back through the trap 49. The drain valve 50 is configured by an electromagnetic open / close valve, and is opened when the temperature of the water 33 in the liquid tank 32 rises as instructed by the controller 47, and discharges the water 33 into the sewage through the drain pipe 48.

  End of drainage is performed by a timer provided in the controller 47 or detection by the water level detection unit 36, and after closing the drainage valve 50 again, the water supply valve 52 provided in the middle of the water supply path 44 is opened and the liquid tank 32 is opened. Inject new water 33.

The position where the water supply path 44 is connected to the liquid tank 32 is located above the space 35 of the liquid tank 32. This is to prevent the water 33 stored in the liquid tank 32 from flowing back and entering the water supply path 44. The water supply path 44 branches off from a part of the water supply pipe 53 for the faucet 6 of the kitchen 1. The water supply path 44 connects a water supply valve 52, a water supply check valve 54, and a vacuum breaker 55 from the water supply pipe 53 side. The water supply check valve 54 prevents a part of the water distribution pipe 48 from being clogged, so that sewage rises and flows backward through the trap 49, so that it does not flow from the liquid tank 32 to the upstream of the water supply path 44. Furthermore, by providing a vacuum breaker 55 between the liquid tank 32 and the water supply check valve 54 as a double safety device for preventing sewage backflow, when the water supply pipe 53 side becomes negative pressure for some reason, The air 26 and the water 33 in the space 35 on the liquid tank 32 side are prevented from entering the water supply path 44.

  In the vacuum breaker 55, when negative pressure is generated in the water supply pipe 53, air (in this case, air in the kitchen or the sink 1) is introduced to equalize the atmospheric pressure to prevent backflow from the liquid tank 32 side. Like to do. Further, a receiving container 57 is provided on the side of the vacuum breaker 55 that is open to the atmosphere via a discharge pipe 56, and the water 33 that partially leaks from the liquid tank 32 to the open side of the atmosphere is received by the receiving container 57 and externally To prevent leakage. In the receiving container 57, the leaked water 33 is either naturally dried in the receiving container 57 or informed of the storage state of the water 33 and instructed to the user to be discarded.

  4 is a cross-sectional view showing the configuration of the garbage processing apparatus when the garbage is being fed, and FIG. 5 is a cross-sectional view taken along the line BB of FIG.

  4 and 5, 58 is an intake duct provided around the charging passage 8. The intake duct 58 communicates with a box-shaped intake passage 59 that constitutes an independent space so as to cover the upper portion of the garbage processing chamber 9. A plurality of intake ports 60 that open toward the input passage 8 and communicate with the garbage input port 4 and the intake duct 59 are provided in the upper portion of the intake duct 58. When the inlet lid 7 is placed on the garbage inlet 4 and closed, the inlet 60 is closed by the inlet lid 7 so that the intake duct 58 becomes a sealed space.

  A suction hose 61 is communicated with a part of the intake passage 59, and suction means 62 is provided at the end thereof. The suction means 62 is composed of a high-pressure blower such as a turbo fan or a radial fan. A hybrid deodorizing material 63 is provided in the middle of the suction hose 61 upstream of the suction means 62. When the garbage 10 is dropped from the garbage input 4 into the garbage container 13 via the input passage 8, if the drying process is performed in the garbage processing chamber 9, water vapor and odor generated from the collected garbage 16 , The suction passage 62 is actuated in accordance with an instruction from the controller 47, and the water vapor and odor are sucked from the intake port 60 provided in the vicinity of the garbage input port 4 to thereby remove the hybrid deodorizing material. Deodorized at 63, and discharged from the exhaust port 64 as odorless air 65, for example, to the kitchen or under the floor.

  The hybrid deodorizing material 63 uses a honeycomb body formed of fiber ceramic as a carrier. In this honeycomb body, a composite compound of manganese, copper and cobalt and a hydrophobic synthetic zeolite are supported using colloidal silica as a binder. The hybrid deodorizing material 63 has a metal complex oxide, and chemically adsorbs hydrogen sulfide, which is an odor component, by the adsorption action of the metal complex oxide. In addition, methyl mercaptan, which is an odor component, is converted into dimethyl disulfide by catalytic action.

  Further, the hydrophobic zeolite constituting the hybrid deodorizing material 63 physically adsorbs odor components such as ammonia in addition to the converted dimethyl disulfide, and is generated during the drying treatment of the input garbage 10 by these combined actions. I try to remove odors. In the hybrid deodorizing material 63, hydrogen sulfide is adsorbed by chemical adsorption. Therefore, if an adsorption site exists in the composite oxide, the adsorption is promoted regardless of the concentration. Therefore, since the lifetime of the hybrid deodorizing material 63 is until this adsorption site disappears, the generation amount of hydrogen sulfide is assumed depending on the amount of the input garbage 10 and the type of the input garbage 10, and the hybrid deodorizing material 63 The timing of replacement etc. is grasped.

  On the other hand, since dimethyl disulfide and ammonia are physically adsorbed, the adsorption capacity changes depending on the concentration and reaches the adsorption capacity in several days to several tens of days. I have to.

  Reference numeral 66 denotes an input cylinder provided in the input passage 8. The input cylinder 66 is molded of a heat-resistant resin that can withstand the drying temperature (for example, 70 to 100 ° C.) of the input garbage 10, as with the input passage 8, and a protrusion 67 provided on the input passage 8. It is detachably provided in the form of being hooked on.

  Further, since the inner wall of the input cylinder 66 is soiled by the input garbage 10, the input port lid 7 of the garbage input port 4 is easily opened to the outside by a handle (not shown) so that the worker can clean it at any time. It can be pulled out. Further, the upper portion of the charging tube 66 is pressed against the lower portion 68 of the charging port lid 7 so that the sealing property of the entire charging passage 8 is maintained. The lower portion 68 of the insertion port lid 7 is made of an elastic heat-resistant material (for example, rubber or silicon) so as to improve the sealing performance. Further, the lower wall 68 of the inlet lid 7 and the inner wall surface of the inlet cylinder 66 are coated with a water-repellent material, and the odor generated during the drying process of the input garbage 10 is contained in the water vapor, It does not stick and remain.

  Reference numeral 69 denotes a top panel display unit which is provided on the top plate 5 in the vicinity of the garbage input port 4 and is composed of an input instruction switch for the input garbage 10 and a confirmation lamp (not shown). Reference numeral 70 denotes a front plate display unit configured by a take-out instruction switch (not shown) and a confirmation lamp (not shown) when the front plate 23 of the kitchen 1 is pulled out and the garbage container 13 is taken out.

  Reference numeral 71 denotes an exterior that accommodates all the above-described components and constitutes the garbage disposal device 72.

  FIG. 6 is a diagram showing a state in which the garbage container 13 is pulled out from the opening 12 of the garbage processing chamber 9 and the collected garbage 16 is discarded.

  In FIG. 6, the garbage container 13 is attached to the front plate (decorative plate) 23 of the sink 1 such that the front plate 21 of the garbage container 13 is inserted from above. The front plate 23 of the sink is generally pulled out to the front side of the sink 1 using a rail structure (not shown) in the same manner as the drawer provided on the sink 1. By pulling out the front plate 23, the garbage container 13 can be taken out freely. By pushing the front plate 23 into the sink 1, the packing 22 attached to the front plate 21 of the garbage container 13 is pressed against the side wall of the garbage processing chamber 9, and the garbage container 13 is sealed in the garbage processing chamber 9. It is made to store in the state where it was done.

  FIG. 7 is a diagram illustrating an operation when the regeneration operation of the hybrid deodorizing material 63 is being performed.

  In FIG. 7, the suction hose 61 is closed by a passage switching damper 73 provided in the middle of the suction hose 61 that is closed from the inlet cover 7 and communicated from a part of the intake passage 59. 59 is sealed. An inlet passage 74 is provided by branching to the suction hose 61 on the downstream side of the passage switching damper 73, and external air 75 from the inside of the exterior 71 or the kitchen flows into the suction hose 61 from an inlet 76 communicating with the introduction passage 74. I try to let them.

The passage switching damper 73 opens and closes the suction hose 61 or the introduction passage 74 by rotating a stepping motor (not shown) or a solenoid (not shown) in the plate-like operating portion. The sucked external air 75 passes through the hybrid deodorizing material 63 by the operation of the suction means 62. When the inlet lid 7 is opened, the passage switching damper 73 opens the suction hose 61, closes the introduction passage 74, and sucks the steam and odors of the collected garbage 16 from the intake port 60. The material 63 is deodorized. The inlet 76 is provided with a filter (not shown) so as to prevent dust and dust from entering the hybrid deodorizing material 63.

  In the present embodiment, the condensation deodorizing device 27 provided between the garbage processing chamber 9 and the intake passage 58 via the circulation path 28, the intake duct 58 provided around the charging passage 8, and intake air into the intake duct 58. The suction means 62 communicated through the passage 59 and the hybrid deodorizing material 63 provided between the suction means 62 and the intake duct 58 were mounted on the sink 1, and they were separated into independent garbage processing devices (stand-alone type). ). In this case, a water tank (not shown) for replacing the water 33 in the liquid tank 32 of the condensing deodorization device 27 and a tank (not shown) for storing moisture generated from the input garbage 10 are added. With this configuration, the worker can perform the drying process of the garbage while preventing odor at an appropriate place.

  The operation and action of the garbage processing machine in the present embodiment configured as described above will be described.

  First, in order to process the garbage generated in the kitchen sink 1, the operator looks at the top panel display unit 69 in the vicinity of the insertion port lid 7 and confirms the current operating state of the garbage processing device 72. For example, if the drying process of the input garbage 10 put on the previous day is completed, the worker discards it in a garbage bag or puts a new input garbage on the input garbage 10 after drying. It is determined whether 10 is added and the drying process is performed.

  When it is desired to newly add the input garbage 10 and perform the drying process, an instruction to open the input port lid 7 is given by the instruction switch of the top panel display unit 69. An operator who has received permission to open the inlet cover 7 (in this case, a notification lamp is lit) informs the inside of the input cylinder 66 from the garbage inlet 4 by opening the inlet lid 7. Along with this, new input garbage 10 is charged into the garbage container 13.

  At this time, if an instruction to open the inlet cover 7 is given by the instruction switch of the top panel display unit 69, the suction means 62 is actuated by the instruction of the controller 47, and the intake duct 58 provided around the inlet passage 8. A system for sucking the air 26 in the garbage processing chamber 9 from a plurality of intake ports 60 is entered. When the input port lid 7 is opened during the drying process in the garbage processing chamber 9, water vapor and odor generated from the collected garbage 16 rises in the input cylinder 66, and this rises. The air 26 and the air in the vicinity of the sink 1 are sucked from the intake port 60 so that the odor does not reach the operator.

  The water vapor and odor sucked from the suction port 60 pass through the suction duct 58 from the suction duct 58 while being diluted with the air in the vicinity of the sink 1, and the hybrid deodorizing material 63 provided in the middle of the suction hose 61 upstream of the suction means 62. The deodorized air is discharged from the exhaust port 64 to the kitchen as odorless air 65. The flow rate of air in the vicinity of the sink 1 including water vapor and odor sucked by the suction means 62 is set to approximately 200 to 300 L / min, and suction is performed from the intake port 60 at a flow rate exceeding the flow rate of the rising air 26. So that the odor is not missed.

  When the input operation of the input garbage 10 is completed and the input port lid 7 is closed, the suction means 62 is stopped by an instruction from the controller 47. When the operator closes the loading port lid 7, the drying process of the charged garbage 10 in the garbage processing chamber 9 is automatically started, or an operation switch provided on the top panel display unit 69 is turned on. Then, the drying process of the new input garbage 10 is started. When the operation switch is turned on, the drive means 17 is actuated by the instruction of the controller 47, the garbage agitation means 14 in the garbage container 13 is rotated, and the collected garbage 16 is inverted and agitated.

Moreover, the heating means 24 provided in the lower part of the garbage processing chamber 9 act | operates, the garbage container 13 is heated, and the temperature of the collection | recovery garbage 16 inside is raised. Further, the air supply means 25 is activated, and the air 26 circulates in the circulation path 28.

  Since the amount of water vapor varies depending on the amount of input garbage 10, the circulation amount of the air 26 by the air supply means 25 needs to be assumed to be a capacity that is desired to be stored in the garbage container 13. For example, assuming that the daily input garbage 10 is 700 g in an ordinary household and the drying processing time is about half a day, the circulation rate can be set to approximately 2 to 20 L / min. Further, in the outgoing pipe 37 of the circulation path 28, the air 26 pushed out by the air supply means 25 is heated by the upper heating means 40, and the collected garbage 16 is collected from the air supply port 39 as dry air 26 having a reduced relative humidity. To spout toward

  When the recovered garbage 16 is dried, a large amount of water vapor and odor is generated from the recovered garbage 16, and this is absorbed by the air 26, and the maximum is exhausted as saturated steam with a relative humidity of 100%. 30 is sent as exhaust 29 to a condensation deodorization device 27 provided in the middle of the return pipe 31 of the circulation path 28. In the condensing deodorization device 27, the exhaust gas 29 is ejected as bubbles through the nozzle 34 into the water 33 stored in the liquid tank 32. Since the bubbles of the exhaust gas 29 pass through the water 33, a large amount of water vapor contained in the exhaust gas 29 having a high temperature is cooled by the water 33, condensed, contained in the water 33 and removed, and air having a small absolute humidity. 26.

  Further, the odor contained in the exhaust gas 29 (for example, main bad odors generated when the input garbage 10 is dried include hydrogen sulfide, trimethylamine, methyl mercaptan, aldehydes, etc.) are often water-soluble. Therefore, they are absorbed in the water 33 and become deodorized air 26. The air 26 is again sucked into the air supply means 25 from the suction inlet 38 of the condensing deodorization device 27 and flows through the circulation path 28.

  In the condensation deodorization device 27, the temperature of the water 33 in the liquid tank 32 rises as the drying process in the drying process chamber 9 proceeds. Further, the water vapor generated from the input garbage 10 is dissolved in the water 33 and the amount of water 33 is increased. This state is monitored by a water temperature detection unit 45 provided in the liquid tank 32, and the temperature of the water temperature detection unit 45 is a temperature at which the condensing capacity decreases (for example, the temperature of new water starts from 20 ° C. and 60 ° C. When it is detected that the condensing capacity is reduced by half), the water 33 in the liquid tank 32 is replaced by an instruction from the controller 47.

  In order to replace the water 33, first, the drain valve 50 of the drain passage 46 provided in the lower part of the liquid tank 32 is opened, and the water 33 in the liquid tank 32 is discharged into the sewage through the drain pipe 48. After confirming the end of drainage of the water 33 by detecting the timer provided in the controller 47 or the water level detection unit 36 and closing the drain valve 50 again, the water supply valve 52 provided in the middle of the water supply path 44 is opened and the liquid is discharged. Fresh water 33 is poured into the tank 32.

  The amount of water 33 to be supplied is detected by a timer provided in the controller 47 or the detection of the water level detection unit 36, and is necessary for condensing the water vapor generated from the input garbage 10 in the garbage processing chamber 9 for condensation. After confirming that the temperature (in this case, the water temperature at that time) and the amount of water 33 have been stored, the water supply valve 52 is closed to end the replacement work of the water 33, and thereafter this operation is repeated as appropriate. .

  Further, the operator looks at the front plate display unit 70 provided on the front plate 23 of the sink 1 and confirms the current operation state of the garbage disposal device 72. For example, when the drying process of the input garbage 10 put on the previous day is completed, the operator gives an instruction to pull out the front plate 23 in order to put it in the garbage bag and discard it. Use the indicator switch.

An operator who has received permission that the front plate 23 may be pulled out (in this case, notification is made by turning on the confirmation lamp) pulls out the front plate 23 from the sink 1, and the garbage container 13 fitted into the front plate 23. The collected garbage 16 after the drying process in the garbage container 13 is discarded.

  Further, when the deodorizing function of the hybrid deodorizing material 63 is regenerated, the controller 47 first checks the current operating status of the garbage disposal device 72. For example, if the drying process of the input garbage 10 has been completed, the controller 47 determines that the input port lid 7 cannot be opened, operates the passage switching damper 73 provided in the suction hose 61, and performs intake air. The intake hose 61 on the passage 59 side is shut off. Thereby, when the introduction passage 74 is opened and the suction means 62 is operated, the external air 75 in the exterior 71 flows in from the inlet 76 and passes through the hybrid deodorizing material 63 through the introduction passage 74.

  In the hybrid deodorizing material 63, when the external air 75 passes, the physically adsorbed dimethyl disulfide, ammonia, aldehydes and the like are desorbed to regenerate the physical adsorption function. Further, even during the drying process of the input garbage 10, the controller 47 causes the input port lid 7 to keep the next time (for example, 30 minutes to 1 hour after the input garbage 10 has been inserted) After confirming that the input garbage 10 cannot be opened), the passage switching damper 73 is operated to open the introduction passage 74 and the suction means 62 is operated to operate the external air 75 in the exterior 71. Is sent to the hybrid deodorizing material 63 through the introduction passage 74. In this way, since most of the odor generated during the drying process of the input garbage 10 is physically adsorbed, the deodorizing performance can be maintained for a long time by frequently performing the regeneration operation of the hybrid deodorizing material 63.

  As described above, in the present embodiment, the garbage input port 4, the garbage processing chamber 9 provided at the lower part of the garbage input port 4, and the intake duct provided around the garbage input port 4. 58, a suction means 62 communicating with the intake duct 58, and a hybrid deodorizing material 63 provided between the suction means 62 and the intake duct 58. In order to regenerate the hybrid deodorizing material 63, Since the external air 75 different from the air 26 in the garbage processing chamber 9 is circulated to the hybrid deodorizing material 63, when the garbage is introduced, the garbage input port 4 and the input passage 8 connected thereto are connected. Odor is sucked from the intake duct 58 provided in the periphery, and this odor is adsorbed to the hybrid deodorizing material 63, so that the odor of the garbage can be prevented from flowing out from the garbage processing chamber 9.

  Further, the regeneration operation performed in order to maintain the performance of the adsorption and deodorization of the hybrid deodorizing material 63 gradually desorbs the odor component adsorbed from the hybrid deodorizing material 63, so that a state in which the operator cannot recognize it as an odor can be created. . Moreover, since the heating power is not required for the regeneration operation of the hybrid deodorizing material 63, an increase in running cost can be prevented.

  Moreover, the garbage processing apparatus 72 of this Embodiment performs deodorizing during garbage drying processing with the condensation deodorizing apparatus 27 provided in the garbage processing chamber 9 via the circulation path 28 separately from the hybrid deodorizing material 63. Thus, a large amount of water vapor or odor generated from the garbage during the drying process is removed by the condensation deodorization device 27, so that the odor component adsorbed by the hybrid deodorizer 63 when the garbage is introduced is reduced, and the hybrid deodorizer 63 is removed. Playback time can be shortened.

  In addition, since the hybrid deodorizing material 63 in the present embodiment is disposed upstream of the suction means 62, all of the air sucked by the suction means 62 passes through the hybrid deodorizing material 63, and the regenerating operation. Can always supply the necessary air.

Further, by taking in external air 75 for regenerating the hybrid deodorizing material 63 from the outside, air that may contain odor components contained in the air around the garbage treatment chamber 9 is eliminated. In the regeneration operation of the hybrid deodorizing material 63, fresh external air 75 is always used.
Can be supplied and the reproduction operation can be performed efficiently.

  Further, the external air 75 for regenerating the hybrid deodorizing material 63 is supplied from the introduction passage 74 that branches to the suction hose 61 that communicates with the intake duct 58 upstream of the hybrid deodorizing material 63. Since the fresh external air 75 is supplied from the introduction passage 74 while the one suction means 62 is fixed, the regeneration operation can be performed efficiently.

  In addition, the regeneration operation of the hybrid deodorizing material 63 according to the present embodiment can easily open the introduction passage 74 and perform suction by switching the suction hose 61 and the introduction passage 74 with the passage switching damper 73. The hose 61 is closed and the suction hose 61 side is hermetically sealed to isolate the odorous air 26 in the intake duct 58 from the fresh external air 75, so that the regeneration operation can be performed efficiently.

  In addition, the regeneration operation of the hybrid deodorizing material 63 according to the present embodiment is generated from the drying process of garbage by introducing the air in the sink 1 and performing the regeneration operation while deodorizing the interior of the sink 1. It is possible to adsorb various odors accumulated in the sink 1 instead of the air 26 containing the odor to be absorbed by the hybrid deodorizing material 63 and remove it while adsorbing because the concentration is very small. The odor that leaks when the door is opened can be reduced.

  Further, the garbage processing chamber 9 of the present embodiment constitutes a closed path and a closed container when the inlet cover 7 provided in the garbage inlet 4 is closed and the garbage container 13 is stored, By providing the condensation deodorization device 27 and the air supply means 25 in the middle of the circulation path 28, all of the water vapor and odor generated from the garbage container 13 pass through the condensation deodorization device 27, and the water vapor is condensed. While being recovered, the odor component can also be reduced by dissolving or condensing in the liquid tank 32.

  Moreover, the garbage processing apparatus 72 of this Embodiment provides the condensation deodorizing apparatus 27 upstream of the air supply means 25 provided in the middle of the circulation path 28, and supplies the exhaust 29 discharged | emitted from the garbage processing chamber 9 by air. Since the suction action of the means 25 leads to the liquid tank 32 of the condensing deodorization device 27, all the water vapor and odor discharged from the garbage processing chamber 9 are allowed to flow into the liquid tank 32 without leaking outside. The drying performance and deodorizing performance during the drying process can be improved.

  In addition, the garbage processing chamber 9 of the present embodiment is provided with the upper heating means 40 in the circulation path 28 and supplies the air 26 heated by the upper heating means 40 to the garbage processing chamber 9. Since the relative humidity of the air 26 whose absolute humidity has been reduced by the condensation deodorization device 27 is lowered, the transport performance of the water vapor generated in the garbage treatment chamber 9 can be improved.

  Moreover, the condensation deodorization apparatus 27 in this Embodiment condenses and removes the water vapor generated during the drying process of the garbage processing chamber 9 in the liquid tank 32, dissolves and removes the generated odor in the liquid tank 32, and removes the solution. By discharging to the sewage, the moisture generated from the input garbage 10 and the odor generated during the drying process can be caused to flow into the sewage as waste water, so that no bad odor is generated in the kitchen.

The suction means 62 in the present embodiment starts to operate when receiving an instruction to open the inlet cover 7 or when the inlet cover 7 is opened, and the air sucked from the intake duct 58 is converted into the hybrid deodorizing material. Since the steam containing the odor that has risen from the garbage processing chamber 9 through the input passage 8 flows out from the garbage input port 4 into the kitchen, the air in the vicinity of the garbage input port 4 can be obtained. At the same time, the air is sucked into the intake duct 58 and sent to the hybrid deodorizing material 63, so that odor during the drying process from the garbage input port 4 can be prevented from being generated in the kitchen.

  Further, the exhaust gas 29 discharged from the garbage processing chamber 9 in the present embodiment is guided to the liquid tank 32 of the condensing and deodorizing device 27 by the suction action of the air supply means 25, so that the air supply means 25 has Since the air 26 having passed through the condensation deodorizing device 27 has a small absolute humidity and a low temperature and is purified in the liquid tank 32, the air supply means 25 is deteriorated due to odor-containing water vapor or high temperature. And the durability of the air supply means 25 can be improved.

  Moreover, the garbage input port 4 in the present embodiment is configured by providing the input port lid 7 on the top plate 5 of the sink 1, so that it is easy for an operator to throw away the garbage in the sink 2 and clean up after cooking. The housework time such as can be shortened.

  In addition, the exhaust gas 29 from the garbage processing chamber 9 in the present embodiment is ejected as bubbles to the liquid tank 32 of the condensation deodorizing device 27 through the nozzles 34, so that the water 33 and the exhaust gas 29 in the liquid tank 32 contact each other. Increase opportunities and promote removal of odors in exhaust 29 (for example, the main bad odors generated when drying raw garbage is hydrogen sulfide, trimethylamine, methyl mercaptan, aldehydes, etc.) Can do.

  In addition, the condensation deodorization device 27 of the present embodiment condenses the temperature of the water temperature detection unit 45 when the temperature of the condensation temperature decreases (for example, when the temperature of new water starts from 20 ° C. and increases to about 60 ° C. When the controller 50 detects that the water 33 in the liquid tank 32 is replaced, the temperature of the water 33 in the liquid tank 32 is always kept low. It is possible to improve the condensing ability to condense water vapor contained in the exhaust 29 from the garbage processing chamber 9. Moreover, by dew condensing an odor component having a high boiling point (for example, methyl sulfide, aldehydes, etc.), the amount generated can be reduced by liquefying or dissolving.

  As described above, the garbage processing apparatus according to the present invention can prevent a bad smell from being emitted to the kitchen even when the garbage is thrown in or during the garbage drying process. It can also be applied to other garbage disposal devices.
