Description

  The present invention relates to a garbage disposal apparatus built in a sink.

  2. Description of the Related Art Conventionally, this type of garbage processing apparatus is used for drying and reducing the amount of garbage generated in a sink in a general household, and is used in a sink (see, for example, Patent Document 1). FIG. 8 shows a conventional garbage disposal apparatus described in Patent Document 1. In FIG.

  This garbage disposal apparatus includes a heater 3 and a blower fan 4 for heating the garbage in the garbage disposal container 2 disposed in the main body 1 with warm air, and a stirring means 5 for agitating the garbage. In order to attach and detach the garbage processing container 2, an openable / closable lid 6 and a packing 7 are provided. The exhaust fan 8 is for exhausting the exhaust gas such as steam and odor components generated at the time of drying loss of the garbage to the outside of the main body 1. It is discharged out of the main body 1 through a catalyst deodorizing device 11 that removes odorous components in the exhaust.

  In addition, the catalyst deodorizing apparatus 11 is provided with a plate carrying a substance such as platinum and an electric heater for heating the plate in order to deodorize the odor of the exhaust passing therethrough by an oxidation reaction. The intake port 12 is for introducing outside air into the garbage disposal container 2. The main body 1 is configured to be pulled out by a slide rail 15 or the like into a storage portion 14 stored in a sink 13. Further, the front panel 16 is located on the front surface of the main body 1 and becomes an appearance portion when stored, and an air supply port 17 is provided in a part thereof. Further, the storage unit 14 is provided with an air supply / exhaust means 18 and an exhaust passage 19 leading from the storage unit 14 to the outdoors.

  The operation of the garbage disposal apparatus configured as described above will be described.

  In the garbage processing apparatus configured as described above, the garbage in the garbage processing container 2 is heated by the heater 3 and the blower fan 4 and simultaneously dried while being agitated and pulverized by the agitating means 5. Vapor and odor components generated in the garbage drying step are sucked by the discharge fan 8, pass through the discharge path 10, and are sent from the garbage processing container 2 to the catalyst deodorization apparatus 11.

  In the catalyst deodorizing device 11, the odor component in the exhaust gas is deodorized by the catalytic reaction and discharged out of the main body 1. At this time, since the inside of the garbage processing container 2 is depressurized at the same time, outside air is introduced from the outside through the air inlet 12. Exhaust gas discharged to the outside of the main body 1 passes through an exhaust passage 19 by an air supply / exhaust means 18 and is discharged outdoors. As described above, since the catalyst deodorization device 11 deodorizes and discharges it to the outside, almost no odor is felt, and it is sufficient to mix it with the outside air and exhaust it with the air supply / exhaust means 18.

Japanese Patent No. 4162983

However, in the conventional garbage processing apparatus, the air supply / exhaust means 18 provided in the storage unit 14 has little effect of exhausting to the outside through the exhaust passage 19 when the main body 1 is pulled out. Therefore, when the user throws in the garbage, if the lid 6 is opened during the drying process, the steam containing the odor component filled in the garbage treatment container 2 is diffused at once, and the odor spreads in the room. It had the problem that.

  This invention solves the said subject, and it aims at providing the garbage drying processing apparatus with which an odor does not spread | diffuse indoors even if it throws in garbage during a drying process.

  In order to solve the above-described conventional problems, a garbage processing container for storing garbage according to the present invention, a garbage processing container for storing garbage, and opening and closing the garbage processing container to input the garbage A charging lid, an adsorption deodorizing unit that removes odor components generated from the garbage by adsorption, a suction passage connecting the garbage processing container and the upstream of the adsorption deodorizing unit, the outside, and an upstream of the adsorption deodorizing unit And an air passage connecting the downstream of the adsorption deodorizing unit and the outside, a suction means provided in the exhaust passage, and an upstream of the adsorption deodorizing unit are connected to the suction passage or the Switching means for switching to the air passage, and starts to drive the suction means in response to the opening operation of the charging lid and connects the suction passage and the upstream of the adsorption deodorizing unit by the switching means for a predetermined suction period. Your The exhaust from the processing container is deodorized, and after the predetermined suction period has elapsed, the switching means connects the air passage and the upstream of the adsorption deodorization unit, and starts suction from the air passage to the adsorption deodorization unit To do.

  Then, when the operation of opening the input lid is started for the introduction of garbage, the suction means sucks the odorous component-containing steam and the external air from the garbage processing container into the suction passage, so that the steam does not diffuse into the room. . Then, the steam is diluted with external air and flows into the adsorption / deodorization unit, and the odor component is adsorbed by the adsorption / deodorization unit, so that the air containing the deodorized vapor is exhausted from the exhaust passage. Next, when the predetermined suction period elapses, the switching unit connects the air passage and the upstream of the adsorption / deodorization unit, so the suction unit starts to suck external air from the air passage to the adsorption / deodorization unit. As a result, the air passing through the adsorption / deodorization unit desorbs the odor component adsorbed by the adsorption / deodorization unit from the adsorption / deodorization unit, so that the regenerated adsorption / deodorization unit can adsorb the odor component again.

  As described above, according to the present invention, it is possible to provide a garbage disposal apparatus in which odors do not diffuse into the room even when garbage is input during the drying process of garbage.

1st invention is a garbage processing container which accommodates garbage, the input lid | cover for opening and closing the said garbage disposal container and throwing in the said garbage, and adsorption | suction which removes the odor component generated from the said garbage by adsorption | suction A deodorizing section, a suction passage connecting the garbage disposal container and the upstream of the adsorption deodorizing section, an air passage connecting the outside and the upstream of the adsorption deodorizing section, and a downstream and the outside of the adsorption deodorizing section. An exhaust passage to be connected; suction means provided in the exhaust passage; and switching means for switching the connection between the suction deodorizing unit and the upstream to the suction passage or the air passage, and according to the opening operation of the charging lid After the suction means is started to be driven and the suction passage is connected to the upstream side of the adsorption deodorization unit by the switching means for a predetermined suction period, the exhaust from the garbage processing container is deodorized, and after the predetermined suction period has elapsed , Serial switching by connecting the upstream of the suction deodorizing unit and the air passage by means a food waste treatment apparatus for starting a suction to the suction deodorizing unit from the air passage.

  Then, the suction means is driven when the operation of opening the charging lid is started for the input of garbage during the drying process. Since the suction means sucks the vapor containing odor components and the external air from the garbage processing container into the suction passage, the vapor is diluted with the external air and flows into the adsorption deodorization unit. As a result, even if garbage is input during the drying process, the steam containing the odor component filled in the garbage processing container does not diffuse into the room. And since an odor component is adsorb | sucked by the adsorption | suction deodorization part, the air containing the deodorized vapor | steam is exhausted from an exhaust passage. Next, when the predetermined suction period has elapsed and the suction from the garbage processing container to the suction passage is completed by the suction means, the switching means connects the air passage and the upstream of the adsorption deodorization unit, so the suction means is externally connected. Suction of air from the air passage to the adsorption deodorizing unit is started.

  As a result, the air passing through the adsorption / deodorization unit desorbs the odor component adsorbed by the adsorption / deodorization unit from the adsorption / deodorization unit, so that the adsorption / deodorization unit regenerated by desorption can adsorb the odor component again. That is, even if garbage is input many times during the drying process, the adsorption / deodorization unit adsorbs the odor component, so that the vapor containing the odor component does not diffuse into the room.

  In the second invention, in particular, the switching means of the first invention connects the air passage and the upstream of the adsorption deodorization unit according to the closing operation of the charging lid, and the suction means sucks from the air passage to the adsorption deodorization unit. Therefore, the suction means starts sucking external air from the air passage to the adsorption / deodorization unit.

  As a result, the air passing through the adsorption / deodorization unit desorbs the odor component adsorbed by the adsorption / deodorization unit from the adsorption / deodorization unit, so that the regenerated adsorption / deodorization unit can adsorb the odor component again. That is, even if garbage is input many times during the drying process, the adsorption / deodorization unit adsorbs the odor component, so that the vapor containing the odor component does not diffuse into the room.

  The third aspect of the present invention is a garbage disposal apparatus that is housed in an exterior having an air vent that communicates between the outside and the interior of the first or second aspect of the invention. Therefore, even if the odor component leaks from the garbage processing device for some reason, the odor component leaked from the external air flowing in the garbage processing device is conveyed from the air passage to the adsorption deodorization unit. As a result, since the adsorption / deodorization unit adsorbs the odor component, the ability to desorb the odor component adsorbed from the adsorption / deodorization unit is reduced, but it is possible to prevent the odor component due to direct malodor from leaking to the outside.

  The fourth aspect of the invention is an air-cooling type in which the steam generated from the garbage is cooled and condensed, and the odor component is dissolved or mixed in the condensed water. The external air sucked by the suction means flows from the vent and flows into the adsorption deodorization section after cooling the air-cooled condensation deodorization section. Therefore, the external air takes heat from the air-cooled condensation deodorization unit and the temperature rises, so that the ability to desorb the odor components adsorbed from the adsorption deodorization unit is improved. In other words, external air can be used for both cooling and desorption.

  In the fifth invention, in particular, the switching means of the first or second invention includes an opening / closing means provided in the air passage, and a valve portion formed in the closing lid that closes the suction passage in accordance with the closing operation of the closing lid. Therefore, it is possible to prevent dry dust dust from entering the suction passage when the input lid is closed, and it is possible to configure a switching means simply by adding an opening / closing means, thereby reducing costs.

According to a sixth aspect of the present invention, in particular, the switching means of the first or second aspect includes a resistance portion having a passage resistance larger than the suction passage built in the air passage, and a closing lid that closes the suction passage in accordance with the closing operation of the closing lid. It is comprised from the valve part formed in this.

  This prevents dust from being dried from entering the suction passage when the closing lid is closed, and the suction means starts sucking external air from the air passage to the adsorption / deodorization section. As a result, the air passing through the adsorption / deodorization unit desorbs the odor component adsorbed by the adsorption / deodorization unit from the adsorption / deodorization unit, so that the regenerated adsorption / deodorization unit can adsorb the odor component again. On the other hand, when the charging lid is open, the suction passage has a relatively small passage resistance compared to the air passage, so the suction means sucks the vapor and external air from the suction passage to the adsorption deodorization portion. To start. That is, the switching means can be configured only by adding the resistance portion, and the cost can be greatly reduced.

  In the seventh invention, in particular, the switching means of the first and second or sixth inventions connects the air passage and the upstream of the adsorption deodorizing unit according to the closing operation of the charging lid and enhances the ability of the suction means. A large amount of external air sucked by the suction means from the air passage to the adsorption / deodorization unit can sufficiently desorb the odor components adsorbed by the adsorption / deodorization unit.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the present embodiment.

  1 to 4, the garbage processing container 21 has a substantially rectangular opening 22 formed in an upper portion thereof, and has a built-in stirring means 24 that is rotated by a drive motor 23, and the upper surface of the exterior 25 is deeply recessed. The U-shaped storage unit 26 is removably stored. The rotation shaft of the drive motor 23 and the rotation shaft 24a of the stirring means 24 are connected via a connection mechanism (not shown), and the stirring means 24 can be rotated by the drive of the drive motor 23. Moreover, when the garbage processing container 21 is pulled out from the storage unit 26, the connection by the connection mechanism can be released. A substantially slit-shaped suction port 27 extending in a substantially horizontal direction opens into the storage portion 26 so as to be positioned on the opening portion 22.

  The air inlet 28 and the hot air outlet 29 are arranged apart from each other. Similarly, the condensing inlet 30 and the condensing outlet 31 are arranged apart from each other and are positioned on the opening 22 so as to face the suction port 27. Each of the storage portions 26 is opened. The suction port 27, the air inlet 28, the hot air outlet 29, the condensing inlet 30, and the condensing outlet 31 face the garbage processing container 21.

  As shown in FIG. 3, the input lid 32 that opens and closes when the garbage is input is provided on the upper part of the garbage processing container 21, and is provided on the open end of the upper portion of the storage unit 26 and on one side facing the suction port 27. When the closing lid 32 is closed, the suction port 27 is closed by a valve portion 34 that projects downward from the closing lid 32. The lid opening / closing detection unit 35 that detects opening / closing of the closing lid 32 includes, for example, a magnet 35a and a reed switch 35b. The closing lid 32 is normally used by being closed, and is opened when throwing away garbage.

The adsorptive deodorizing unit 36 has an adsorbent 37 in which a composite oxide (Mn, Co, Cu, etc.) and a hydrophobic zeolite are supported on a carrier (Si, Al ₂ O ₃ etc.) and a hydrophobic zeolite incorporated in a deodorizing container 38, and a suction passage 39. Connects the suction port 27 and the upstream chamber 40 of the adsorption deodorizing unit 36, and the exhaust passage 41 connects the downstream chamber 42 of the adsorption deodorizing unit 36 and the exhaust port 43, and further comprises a fan provided in the exhaust passage 41. The suction means 44 exhausts to the outside.

  The heating means 45 heats the garbage in the garbage processing container 21, and includes a heating unit 46 made up of an electric heater, a heat insulating material, and a container, an outgoing hot air passage 47, a return hot air passage 48, and hot air made up of a fan. The circulation means 49 is comprised. An outgoing hot air passage 47 connects the air inlet 28 and the upstream of the heating unit 46, and a return hot air passage 48 connects the downstream of the heating unit 46 and the hot air outlet 29. Further, the hot air circulation means 49 provided in the outgoing hot air passage 47 circulates the air containing the steam of the garbage processing container 21 from the outgoing hot air passage 47 through the heating unit 46 to the returning hot air passage 48, At this time, the air passing through the heating unit 46 is heated.

  The hot air temperature detector 50 for detecting the heated air temperature is built in the return hot air passage 48, and the air temperature detector 51 for detecting the air temperature of the garbage processing container 21 is an air inlet of the outgoing hot air passage 47. 28 is built in the vicinity. The guide 52 is formed to protrude downward from the charging lid 32 so as to face the hot air outlet 29 in order to flow the hot air jetted from the hot air outlet 29 to the bottom of the garbage disposal container 21. The air flow in the garbage disposal container 21 flows from the hot air outlet 29 to the bottom of the garbage disposal container 21 and then toward the air inlet 28, that is, flows through the garbage disposal container 21.

  The air-cooled condensation deodorizing means 53 removes steam, odor components and heat generated from the garbage, and an air-cooled multi-tube heat exchanger 57 in which a number of condensation pipes 56 are connected to the forward header 54 and the return header 55. And a condensing passage 58, a return condensing passage 59, a condensing circulation means 60 comprising a fan or a suction pump, and an air passage 61 for cooling.

  The condensing pipe 56 is disposed in the air passage 61, and the forward condensing passage 58 connects the condensing inlet 30 facing the garbage disposal container 21 and the outbound header 54, and the return condensing passage 59 is connected to the garbage disposal container 21. The condensing outlet 31 and the return header 55 facing each other are connected to each other, and the condensing circulation means 60 provided in the return condensing passage 59 generates a circulating air flow. The communication passage 62 communicates the upstream chamber 40 and the downstream of the air passage 61, and is provided with opening / closing means 63 (normally in an open state) comprising a drive unit such as a valve and a solenoid for opening and closing the communication passage 62.

  The switching means 64 switches between the suction passage 39 and the air passage 61, and is composed of the valve portion 34 of the closing lid 32 and the opening / closing means 63. Note that the air cooling inlet 65 of the air passage 61 opens into the exterior 25, and the vent 66 opens at the top of the exterior 25 away from the air cooling inlet 65. The drain pipe 67 communicates the bottom of the return header 55 and the water storage tank 68, and is provided with drain opening / closing means 69 including a driving unit such as a valve or a solenoid for opening / closing the drain pipe 67. The water level detectors 70 and 71 for measuring the water level are built in the return header 55 and the detachable water storage tank 68, respectively.

  The control unit controls the drive motor 23, the suction unit 44, the heating unit 46, the hot air circulation unit 49, the condensing circulation unit 60, the opening / closing unit 63, and the drainage opening / closing unit 69.

  In the garbage processing apparatus configured as described above, an operation after discarding dried garbage from the garbage processing container 21 will be described.

As shown in FIG. 5, when opening the input lid 32 in order to input the garbage generated by cooking or the like into an empty garbage processing container 21, the lid open / close detection unit 35 detects the opening operation of the input lid 32. In response to this opening detection, the controller drives the opening / closing means 63 to close the communication passage 62 and simultaneously drives the suction means 44. The suction port 27 is opened from the valve portion 34 of the charging lid 32 and faces the outside.

  As shown in FIG. 2, the odor-free air (no steam) in the garbage disposal container 21 and external air flow into the suction passage 39 from the suction port 27 by the suction action of the suction means 44, and the upstream chamber 40. The air homogenized in the upstream chamber 40 passes through the adsorbent 37, enters the exhaust passage 41 from the downstream chamber 42, and is exhausted from the exhaust port 43 to the outside. At that time, the adsorbent 37 is desorbed by the air passing through, and the odor components such as dimethyl disulfide and acetaldehyde that have been physically adsorbed are desorbed, and the adsorption function of the adsorbent 37 is regenerated. However, although the desorption speed is slow and the amount of odor components to be desorbed per unit time is small, the adsorption capacity of the adsorbent 37 is regenerated to a level that does not cause odor (odor intensity less than 1) over a long period of time during drying. The

  Subsequently, after the lid opening / closing detection unit 35 detects the opening operation of the closing lid 32 and measures the time, after a predetermined period of suction has elapsed, the control unit drives the opening / closing means 63 to open the communication passage 62. Therefore, the suction capability of the suction means 27 flowing from the suction port 27 to the suction passage 39 is weakened by the amount of external air flowing from the vent hole 66 to the air passage 61 by the suction action of the suction means 44 that is being driven. As a result, the wind noise generated from the air passing through the suction port 27 is weakened, so that the noise can be reduced. The predetermined suction period is a time required for the suction means 44 to suck most of the air and steam in the garbage disposal container 21 into the suction passage 39, and is about 1 to 10 minutes.

  Thereafter, when the input of garbage is finished and the closing lid 32 is to be closed again, the open state of the communication passage 62 and the driving of the suction means 44 are continued even when the lid opening / closing detection unit 35 detects the closing operation of the closing lid 32. To do. In addition, even when the input of garbage ends in a short time and the suction passage 63 is closed, the control unit gives priority to opening the communication passage 62 by driving the opening / closing means 63. . At the same time, the control unit starts driving the drive motor 23, the heating unit 46, the hot air circulation unit 49, and the condensation circulation unit 60. The drive motor 23 is driven during an agitation period (for example, 10 to 60 seconds, two forward rotations and one reverse rotation), and thereafter intermittently operates at a predetermined interval (5 to 30 minutes). That is, the drive motor 23 intermittently rotates the stirring means 24 via the connection mechanism.

  Further, the air in the garbage processing container 21 goes from the air inlet 28 through the hot air passage 47 by the suction action of the driven hot air circulation means 49, and then the air flows into the heating unit 46. At that time, the air passing through the heating unit 46 is heated to form hot air, and the hot air passes through the returning hot air passage 48 and is jetted from the hot air outlet 29 toward the guide unit 52. Next, the warm air is turned downward by the guide unit 52 and flows toward the garbage in the garbage processing container 21. As a result, warm air collides with the garbage and heats it, and steam containing odor components (hydrogen sulfide, methyl mercaptan, trimethylamine, acetaldehyde, etc.) is generated from the garbage whose temperature has risen. On the other hand, the hot air blown out from the hot air outlet 29 forms a circulating flow in the garbage processing container 21 and sufficiently flows into the air inlet 28 as air containing steam while being sufficiently mixed with the generated steam to lower the temperature. .

On the other hand, due to the suction action of the driven condensing and circulating means 60, a part of the air containing the vapor in the garbage processing container 21 goes from the condensing inlet 30 through the condensing passage 58, and then the air flows into the outgoing header 54. Then, the air is made uniform by the forward header 54 and flows into a large number of condensing pipes 56. (For example, 5 to 20 L / min)
As shown in FIGS. 3 and 4, external air passes through the interior of the exterior 25 from the vent 66 due to the suction action of the suction means 44, and then the external air flows along the periphery of the storage portion 26 and the air cooling inlet 65. To. Subsequently, the outside air passes through the air passage 61 and flows into the upstream chamber 40 from the communication passage 62. At that time, since the external air cools the condensing pipe 56, the air containing the vapor passing through the condensing pipe 56 is deprived of heat and condensed on the inner wall of the condensing pipe 56, and the generated condensed water is returned to the return header 55. Fall to and accumulate. (Dehumidification)
And since condensed water melt | dissolves odor components, such as hydrogen sulfide, a trimethylamine, and a methyl mercaptan, deodorization can be aimed at. As a result, it is possible to prevent the odor component from adhering to the dry waste again, and the odor of the dry waste itself is reduced.

  Further, the dried air from which vapor, odor components and heat have been removed by condensation returns from the return header 55, passes through the condensation passage 59, and returns from the condensation outlet 31 to the garbage disposal container 21. By this operation, air containing odor components does not leak to the outside, and the garbage is dried. In particular, since the warm air forms a circulation flow in the garbage processing container 21, the steam generated from the garbage separates from the garbage and efficiently flows into the condensing inlet 30, thereby reducing the drying time and improving the thermal efficiency. I can plan.

During drying of the garbage, the external air flowing into the upstream chamber 40 passes through the adsorbent 37, enters the exhaust passage 41 from the downstream chamber 42, and is exhausted to the outside through the exhaust port 43. At that time, the adsorbent 37 is desorbed little by little over a long period of time such as dimethyl disulfide and acetaldehyde that have been physically adsorbed by the passing air, and the adsorption function is regenerated. (Odor intensity less than 1)
Even if the odor component leaks from the heating unit 46, the hot air circulation unit 49, the condensation circulation unit 60, etc. for some reason, the external air flowing along the periphery of the storage unit 26 absorbs the odor component to the adsorption deodorization unit 36. Since it is conveyed, the adsorbent 37 adsorbs the odor component. As a result, the desorption ability of the odor component that has been physically adsorbed from the adsorbent 37 is reduced, but it is possible to prevent the odor component due to direct bad odor from leaking to the outside.

  When the water level detection unit 70 detects that the water level of the return header 55 has reached the threshold value (when the passage resistance is remarkably increased by condensed water or when condensed water returns and rises the condensation passage 59), the control unit returns the condensation level. 59 is opened for a certain period, and the condensed water in the return header 55 is transferred to the water storage tank 68. Further, when the water level detection unit 71 detects that the water storage tank 68 is full, an alarm is issued to prompt the user to take out the water storage tank 68 and drain it. Alternatively, when the water level detection unit 71 detects that the water storage tank 68 is full, the charging lid 32 may not be opened.

  When opening the input lid 32 in order to input the garbage again during the drying of the garbage, the suction port 27 is opened from the valve portion 34 of the input lid 32, and the lid open / close detection unit 35 is opened by the input lid 32. When the opening is detected, the controller drives the opening / closing means 63 to close the communication passage 62. The driving of the suction means 44 is continued. At the same time, the control unit stops the drive motor 23, the heating unit 46, the hot air circulation means 49, and the condensation circulation means 60, so that heating to the garbage is eliminated and the generation of steam is drastically reduced.

  In other words, when the charging lid 32 is opened, the generation of new odor components is suppressed, so that the odor does not diffuse outside if the steam containing the odor components filled in the garbage disposal container 21 is deodorized. In particular, since the suction port 27 is provided at a position opposite to the hinge 33, even if the charging lid 32 is slightly opened and vapor containing odorous components is about to flow out to the outside, the suction port 27 passes through the suction port 27 side. Therefore, the vapor is reliably sucked from the suction port 27.

  As shown in FIG. 2, the steam containing the odor component of the garbage disposal container 21 flows into the suction passage 39 from the suction port 27 by the suction action of the suction means 44 together with the external air and reaches the upstream chamber 40. As a result, it is possible to prevent the vapor containing the odor component from leaking to the outside through the opening 22, and the odor does not diffuse outside.

  Then, when the vapor and air containing the odor component homogenized in the upstream chamber 40 pass through the adsorbent 37, the odor component is adsorbed on the adsorbent 37, so that the deodorized vapor and air are in the downstream chamber 42. From the exhaust port 43 to the outside. As a result, the odor can be prevented from diffusing to the outside.

Adsorption and deodorization has the following three types. First, hydrogen sulfide is a complex oxide (Mn, Co, C
u and the like). Second, methyl mercaptan is physically adsorbed to hydrophobic zeolite after being converted to dimethyl disulfide by the catalytic action of complex oxides (Mn, Co, Cu, etc.). Third, acetaldehyde, dimethyl sulfide, etc. are physically adsorbed on hydrophobic zeolite.

  In addition, in the air passing through the adsorbent 37, the chemically adsorbed hydrogen sulfide cannot be desorbed from the adsorbent 37. That is, the life of the adsorbent 37 is dominated by hydrogen sulfide. However, hydrogen sulfide desorbs and regenerates when the adsorbent 37 is heated. However, since the desorbed hydrogen sulfide has a high concentration, it has a strong odor and is not practical. In addition, the steam containing odor components is mixed with the external air in the suction passage 39 and the upstream chamber 40 to reduce the relative humidity, and the steam is also dissolved in the condensed water condensed in the adsorbent 37. By further reducing the relative humidity, it is possible to prevent the passage from being blocked.

  Subsequently, after the lid opening / closing detection unit 35 detects the opening operation of the closing lid 32 and measures the time, after a predetermined period of suction has elapsed, the control unit drives the opening / closing means 63 to open the communication passage 62. As a result, the suction capability of flowing from the suction port 27 to the suction passage 39 is weakened by the amount of external air that flows from the ventilation port 66 to the air passage 61 by the suction action of the driven suction means 44.

  As a result, the wind noise generated from the air passing through the suction port 27 is weakened, so that the noise can be reduced. The predetermined suction period is the time required for the suction means 44 to suck most of the air and vapor in the garbage processing container 21 into the suction passage 39, and depends on the capacity of the suction means 44 and the volume of the garbage processing container 21. Although it depends, it is about 1 to 10 minutes.

  Therefore, after the predetermined suction period has elapsed, almost no odor-containing steam remains in the garbage disposal container 21, so that the steam diffuses into the room even if the suction ability flowing from the suction port 27 to the suction passage 39 is weak. There is nothing. In addition, the external air flowing in from the suction port 27 and the vent port 66 by the suction action of the suction means 44 regenerates the adsorbent 37 even after the predetermined suction period has elapsed and until the closing lid 32 is to be closed again. To do.

  Next, when the input lid 32 is opened during the drying of the raw garbage, the raw garbage is input and the input lid 32 is to be closed, the suction port 27 is closed by the valve portion 34 of the input lid 32 and the lid is opened and closed. The detector 35 detects the closing operation of the closing lid 32. At this time, the open state of the communication passage 62 and the driving of the suction means 44 are continued.

  In addition, even when the input of garbage ends in a short time and the suction passage 63 is closed, the control unit gives priority to opening the communication passage 62 by driving the opening / closing means 63. . At the same time, the control unit restarts driving of the drive motor 23, the heating unit 46, the hot air circulation unit 49, and the condensation circulation unit 60, so that drying of garbage and regeneration of the adsorbent 37 (desorption of odor components) resume. Is done. Odor components such as dimethyl disulfide and acetaldehyde, which flow into the vent 66 by the suction action of the suction means 44 and pass through the air passage 61 and the adsorption / deodorization unit 36 and physically adsorbed on the adsorbent 37, The adsorption function of the adsorbent 37 is regenerated by desorbing little by little over several hours. (Odor intensity less than 1) As a result, even if the charging lid 32 is subsequently opened during drying, the adsorption deodorization unit 36 can reliably adsorb and deodorize odor components contained in the steam.

  Thereafter, as the drying of the garbage progresses and the generation of steam decreases, the amount of heat required for evaporation decreases, and the temperature of the air in the garbage processing container 21 and the temperature of the hot air ejected from the hot air outlet 29 increase. To rise. Therefore, when the output of the hot air temperature detection unit 50 or the air temperature detection unit 51 rises and the output or output difference exceeds the drying threshold value (set by experimenting the completion of drying after the garbage is dried), Judge that the garbage is dry. As a result, the control unit stops the drive motor 23, the suction unit 44, the heating unit 46, the hot air circulation unit 49, and the condensation circulation unit 60.

Note that an opening / closing means may be provided in the suction passage 39 instead of the valve portion 34. Further, a three-way valve that switches between the suction passage 39 and the communication passage 62 may be provided instead of the valve portion 34 and the opening / closing means 63.

(Embodiment 2)
A garbage disposal apparatus according to Embodiment 2 of the present invention will be described with reference to FIGS. FIG. 3 is a right side cross-sectional view showing the BB cross-sectional configuration in FIG. 1 of the garbage disposal apparatus in Embodiment 2, and FIG. 4 is a left side cross-section showing the CC cross-sectional configuration in FIG. FIG. 7 is a front sectional view showing the AA cross-sectional configuration in FIG. 3 of the garbage disposal apparatus, and FIG. 7 is a front sectional view showing the AA sectional configuration in FIG. 3 of the garbage disposal apparatus.

  Hereinafter, the same parts as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. The difference from the first embodiment is that the switching means 72 is composed of a resistance portion 73 having a passage resistance larger than that of the suction passage 39 built in the communication passage 62 and the valve portion 34, and in addition, according to the closing operation of the closing lid 32. The switching means 72 connects the air passage 61 and the adsorption / deodorization unit 36 and enhances the ability of the suction means 44.

  In order to throw in the garbage again during the drying of the garbage, when the introduction lid 32 is opened, the suction port 27 is opened from the valve portion 34 of the insertion lid 32. The control unit continues to drive the suction unit 44 while stopping the drive motor 23, the heating unit 46, the hot air circulation unit 49, and the condensation circulation unit 60. At this time, the passage resistance of the suction passage 39 is much smaller than that of the resistance portion 73, so that the suction means 44 sucks the steam containing the odor component of the garbage processing container 21 and the outside air as shown in FIG. Suction from the mouth 27 to the adsorption deodorization unit 36.

  As a result, it is possible to prevent the vapor containing the odor component from leaking to the outside through the opening 22, and the odor does not diffuse outside. In addition, since there is little air which flows into the adsorption | suction deodorizing part 36 through the resistance part 73, the adsorption | suction deodorizing performance of the adsorption | suction deodorizing part 36 does not deteriorate remarkably.

  On the other hand, dry dust can be prevented from entering the suction passage 39 by the valve portion 34 when the closing lid 32 is closed, and at the same time, the suction means 44 adsorbs and deodorizes external air from the air passage 61 through the resistance portion 73. Aspirate to part 36. As a result, the air passing through the adsorption / deodorization unit 36 desorbs the odor component adsorbed by the adsorbent 37 from the adsorbent 37, so that the regenerated adsorbent 37 can adsorb the odor component again. That is, the opening / closing means 63 is not necessary, and the switching means 72 can be configured simply by adding the resistance portion 73, so that the cost can be greatly reduced.

  In addition, in order to cover the passage resistance of the resistance portion 73 according to the closing operation of the closing lid 32, the number of rotations of the suction means 44 is increased to increase the suction capability. As a result, since the external air sucked by the suction means 44 from the air passage 61 through the resistance portion 73 to the adsorption / deodorization unit 36 increases, the desorption ability of the odor component adsorbed on the adsorbent 37 can be improved and maintained. .

  In addition, each embodiment mentioned above may be implemented as illustrated, and may be implemented combining these.

  As described above, the garbage disposal apparatus of the present invention does not diffuse odor even if garbage is input during the drying process, so it can be built in a sink such as a home system kitchen or a hotel kitchen. it can.
