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. 12 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 when reducing the amount of dry garbage to the outside of the main body 1. The exhaust outlet 8, the discharge path 10, 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 disposal apparatus according to the present invention includes a garbage disposal container that accommodates garbage, an input lid that opens and closes the garbage disposal container and inputs the garbage. An adsorption deodorization unit that removes odor components generated from the garbage by adsorption, a suction passage that connects the garbage processing container and the upstream of the adsorption deodorization unit, and an air that connects the outside and the upstream of the adsorption deodorization unit A passage, an exhaust passage connecting the downstream of the adsorption deodorizing unit and the outside, a suction means provided in the exhaust passage for exhausting the air in the adsorption deodorizing unit to the outside, and a connection between the upstream of the adsorption deodorizing unit Switching means for switching to the suction passage or the air passage, the suction means starts driving in response to the opening operation of the charging lid, and the switching means connects the suction passage and the upstream of the adsorption deodorization unit. Connected After the predetermined suction period elapses or when the switching means connects the air passage and the upstream of the adsorption deodorizing unit according to the closing operation of the charging lid, the suction means continues to be driven for a predetermined period of time. To do.

  When the operation of opening the input lid is started for discharging the input of garbage, the suction means sucks the odorous component-containing steam and external air from the garbage processing container into the suction passage, so that the steam enters the room. Does not spread. 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 or the closing operation of the charging lid is started, the switching unit connects the air passage and the upstream of the adsorption deodorizing unit, and the driving of the suction unit continues from this time for the predetermined regeneration period. To do. During the predetermined regeneration period, the suction means continues to suck external air from the air passage to the adsorption / deodorization unit, so that the air passing through the adsorption / deodorization unit desorbs the odor components adsorbed by the adsorption / deodorization unit from the adsorption / deodorization unit.

  As described above, according to the present invention, it is possible to provide a garbage disposal device that can easily throw in garbage and does not diffuse odor into the room even if garbage is thrown in during the drying process.

  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; a suction means provided in the exhaust passage for exhausting the air in the adsorption / deodorization section to the outside; and a switching means for switching the connection with the upstream of the adsorption / deodorization section to the suction passage or the air passage. The suction means starts driving in response to the opening operation of the charging lid, and a predetermined suction period elapses after the switching means connects the suction passage and the upstream of the adsorption deodorizing unit, or Throw Closing said switching means reproducing predetermined period by connecting the upstream of the suction deodorizing unit and the air passage in response to the a garbage disposal unit to continue driving of the suction means.

  As a result, the suction means starts to be driven when the input lid is opened to input 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 a predetermined suction period elapses or the closing operation of the charging lid starts, that is, when the suction means finishes the suction from the garbage processing container to the suction passage, the switching means switches between the air passage and the upstream of the adsorption deodorization unit. And the driving of the suction means continues from this time for a predetermined period of regeneration. During the predetermined regeneration period, the suction means continues to suck external air from the air passage to the adsorption / deodorization unit, so that the air passing through the adsorption / deodorization unit desorbs the odor components adsorbed by the adsorption / deodorization unit from the adsorption / deodorization unit. As a result, the adsorption deodorization part regenerated by desorption can adsorb odor components again. That is, even if garbage is input many times during the drying process, the adsorption and deodorization unit adsorbs the odor component, so that the vapor containing the odor component can be prevented from diffusing into the room.

  The predetermined regeneration period is set by the amount of the odor component sucked into the suction passage. For example, when the steam containing the odor component from the garbage disposal container is sucked into the suction passage in about 1 minute, the predetermined regeneration period is the drying time. Equivalent to about 4-9 hours. Then, even if the garbage drying process is completed during the predetermined regeneration period, the suction means is continuously driven until the predetermined regeneration period elapses to complete the regeneration of the adsorption deodorizing unit.

  In particular, the second invention includes condensation deodorizing means for removing odor components generated from the garbage of the first invention and heating means for heating the garbage, and the regeneration predetermined period is 3 to 3 from the start of operation of the heating means. When opening the closing lid after 4 hours, it is set short.

  As a result, when the charging lid is opened within 3 to 4 hours from the start of operation of the heating means in the first half of the drying when the generation amount of steam containing odorous components increases as the temperature of the garbage by the heating means rises, Since a large amount of odor components are adsorbed, the adsorption / deodorization part cannot be completely regenerated by desorption unless the predetermined regeneration period is set.

  On the other hand, since the condensation deodorizing means removes steam, odor components and heat, when the charging lid is opened after 3 to 4 hours from the start of operation of the drying latter heating means where the odor concentration of the garbage disposal container is lowered, Since the adsorbed odor component is small, the adsorption / deodorization unit can complete the regeneration by desorption within a short regeneration predetermined period.

  In other words, in the latter half of drying, the predetermined regeneration period is short, and the drive time of the suction means is short, so that energy saving and low noise can be achieved. Note that the same effect can be obtained by reducing the suction capability of the suction means instead of shortening the predetermined regeneration period.

  In the third invention, in particular, during the predetermined regeneration period of the first or second invention, the charging lid opens during the operation of the heating means for heating the garbage, and the switching means is provided between the suction passage and the adsorption deodorizing unit. The longer the number of times of connection with the upstream, the longer the setting.

  Thus, when the charging lid is opened during the drying process, the suction means sucks most of the vapor containing the odor component in the garbage disposal container into the suction passage. However, the vapor containing the odor component is stored again in the garbage disposal container until the charging lid is opened next time, and the adsorption / deodorization unit also adsorbs the odor component corresponding to the opening every time the charging lid is opened. Therefore, the longer the predetermined regeneration period is set and changed as the number of opening operations of the closing lid is increased, the odorous components adsorbed in large quantities can be sufficiently desorbed, and the regeneration of the adsorption deodorization unit can be completed with certainty. In other words, the smaller the number of times the opening lid is opened during the drying process, the more energy saving and lower noise of the suction means can be achieved.

  In the fourth aspect of the invention, in particular, the suction means of the first to third aspects of the invention stop driving when heating by the heating means is finished by the end of drying of garbage, so that energy saving and low noise can be achieved after the drying is finished. . When the charging lid is opened in the first half of drying, the adsorption / deodorization unit adsorbs a strong odor component, but the regeneration time can be increased. On the contrary, when the charging lid is opened in the latter half of the drying, the adsorption deodorization unit adsorbs a thin odor component, but the regeneration time is short. That is, the regeneration period has not passed, but the adsorption and deodorization unit has almost completely regenerated, and the regeneration period is usually set under the worst conditions such as foods that easily generate odor components and a large amount of garbage. Therefore, there are very few odor problems in actual use.

  In the fifth invention, in particular, when the opening operation of the charging lid according to the first to fourth inventions is not performed for 1 to several days, the switching means connects the ventilation passage and the downstream of the adsorption deodorizing unit, and the suction means Since it is driven for a predetermined period for absence, the moisture and dust in the adsorption deodorizing unit are dehumidified by the external air sucked by the suction means as appropriate, and the dust is discharged. As a result, the adsorption and deodorization part is always hygienic because the growth of mold and fungi is suppressed.

  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.

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.

Opening and closing is possible via a hinge 33 provided on one side. When the closing lid 32 is closed, the suction port 27 is closed by a valve portion 34 that protrudes 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 charging lid 32 is normally used by being closed, and is opened when charging garbage.

The adsorptive deodorizing unit 36 has a deodorizing container 38 with a composite oxide (Mn, Co, Cu, etc.) supported on a carrier (Si, AL ₂ O ₃ etc.) and an adsorbent 37 carrying a hydrophobic zeolite. The suction passage 39 connects the suction port 27 and the upstream chamber 40 of the adsorption / deodorization unit 36, and the exhaust passage 41 connects the downstream chamber 42 and the exhaust port 43 of the adsorption / deodorization unit 36. The suction means 44 comprising a provided fan exhausts 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 blown from the hot air outlet 29 to the bottom of the garbage processing 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. The air cooling inlet 6 of the air passage 61
5 is opened in the exterior 25, and the vent 66 is opened in the upper part of the exterior 25 apart 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, suction unit 44, heating unit 46, hot air circulation unit 49, condensation circulation unit 60, opening / closing unit 63, and 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 control unit drives the opening / closing means 63 to close the communication passage 62, simultaneously drives the suction means 44, and starts measuring the suction time. 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. To. 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 this time, the adsorbent 37 desorbs and regenerates odor components such as dimethyl disulfide and acetaldehyde that have been physically adsorbed by the air passing therethrough. 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 odor (less than odor intensity 1) over a long period of time during drying. The

  When the measured time has passed the predetermined suction period, the control unit drives the opening / closing means 63 to open the communication passage 62, reset the suction time measurement, and start the regeneration time measurement. The suction means 44 sucks external air from the air passage 61 to the adsorption / deodorization unit 36 until the measured time passes the predetermined regeneration period, and the air passing through the adsorption / deodorization unit 36 is physically adsorbed to the adsorbent 37. The deodorized odor component is desorbed from the adsorbent 37.

  On the other hand, 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. Further, the predetermined regeneration period is set by the amount of the odor component physically adsorbed on the adsorbent 37, but in actuality, the adsorption amount of the odor component is very small and cannot be measured.

  Therefore, as shown in FIG. 6, the product of the peak odor component concentration that reaches a peak in about 2 hours after the start of drying and the predetermined suction period is substituted for the odor component adsorption amount. Next, the regeneration predetermined period is obtained by dividing the product of the peak odor component concentration and the suction predetermined period by the odor component concentration (less than odor intensity 1) at which the external air is desorbed from the adsorbent 37. According to a prior experiment, when all the odorous component-containing steam is sucked into the suction passage 39 in about 1 to 2 minutes from the garbage disposal container 21, the predetermined regeneration period is about 4 to 9 hours slightly longer than the drying time. It was. However, the predetermined regeneration period is affected by the amount of garbage, the amount of external air, the amount of heating of the heating unit 46, and so on, and thus correction may be necessary.

  Thereafter, when the input of garbage is finished and the closing lid 32 is to be closed again, even if the lid opening / closing detection unit 35 detects the closing operation of the closing lid 32, the communication passage 62 is opened and the suction means 44 is driven and regenerated. Continue measuring time. However, priority is given to the controller opening the communication passage 62 by driving the opening / closing means 63 even when the input of the garbage ends in a short time and the suction passage 63 is in a predetermined suction period. In addition, the measurement of the regeneration time is started by resetting the measurement of the suction time.

  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 circulation 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, outside air flows 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 shown in FIG. 6, the odor component concentration in the garbage processing container 21 decreases in the latter half of the drying when the amount of the odor component generated from the garbage is lower than the deodorization amount by dissolution. 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.

Further, during the drying process of the garbage and during the predetermined period of regeneration, 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 this time, the adsorbent 37 desorbs and regenerates odor components such as dimethyl disulfide and acetaldehyde that have been physically adsorbed by the air passing therethrough. However, the desorption speed is slow, the amount of odor components to be desorbed is small (odor intensity less than 1), and the adsorbent 37 is regenerated at a level that does not odor.

  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 odor components. 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 is likely to reach a 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 and condenses. The passage 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.

  During the drying process of garbage, when the garbage lid is to be thrown in again during a predetermined regeneration period, when the charging lid 32 is opened, the suction port 27 is opened from the valve portion 34 of the charging lid 32 and the lid is opened and closed. The detection unit 35 detects the opening operation of the closing lid 32, and by this detection, the control unit drives the opening / closing means 63 to close the communication passage 62, resets the regeneration time measurement, and starts the suction time measurement again. To do. 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, it passes through the vicinity of the suction port 27. 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 deodorization has the following three types. First, hydrogen sulfide is chemically adsorbed on a complex oxide (Mn, Co, Cu, etc.). 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 is desorbed and regenerated by heating high temperature air or adsorbent 37. However, since the concentration of the physically adsorbed odor component simultaneously desorbed is high, the odor is strong and impractical. On the other hand, the vapor containing odor components mixes with the external air in the suction passage 39 and the upstream chamber 40 to greatly reduce the relative humidity, so that the passage is blocked by the condensed water condensed in the adsorbent 37. Can be prevented.

  Subsequently, when the measured time has passed the predetermined suction period, the suction time measurement is reset and the regeneration time measurement is started. At the same time, 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, even after the predetermined suction period has elapsed and until the closing lid 32 is about to be closed again, the external air flowing in from the suction port 27 and the ventilation port 66 due to the suction action of the suction means 44 is in the predetermined regeneration period. The adsorbent 37 is regenerated.

  Next, when the input lid 32 is opened during the drying process of the garbage, the garbage is introduced, and the input lid 32 is closed, the suction port 27 is closed by the valve portion 34 of the input lid 32 and the lid is closed. Even when the opening / closing detector 35 detects the closing operation of the closing lid 32, the open state of the communication passage 62, the driving of the suction means 44, and the measurement of the regeneration time are continued.

  However, priority is given to the controller opening the communication passage 62 by driving the opening / closing means 63 even when the input of the garbage ends in a short time and the suction passage 63 is in a predetermined suction period. In addition, the measurement of the regeneration time is started by resetting the measurement of the suction time. 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 again. As a result, the drying of the garbage is resumed, and the regeneration of the adsorbent 37 (desorption of odor components) is performed for a new regeneration predetermined period.

  At that time, odors 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, are physically adsorbed on the adsorbent 37. The components are slightly desorbed and regenerated over a period of several hours. However, the desorption speed is slow, the amount of odor components to be desorbed is small (odor intensity less than 1), and the adsorbent 37 is regenerated at a level that does not odor. As a result, even if the input lid 32 is opened to input garbage during the drying process, the adsorption / deodorization unit 36 can reliably adsorb and deodorize the odor components contained in the steam.

  As shown in FIG. 7, when the input lid 32 is opened during the drying process, the suction means 44 sucks most of the vapor containing the odor component in the garbage processing container 21 into the suction passage 39. Is replaced by external air, the concentration of odor components is significantly reduced, and the temperature is also reduced. However, the steam containing the odor component is stored again in the garbage processing container 21 until the input lid 32 is opened next time, and the adsorption / deodorization unit 36 adsorbs the odor component every time the input lid 32 is opened.

  That is, as the number of opening operations of the charging lid increases, the adsorption / deodorization unit 36 adsorbs odorous components in large quantities. Accordingly, the predetermined regeneration period is lengthened and changed according to the number of opening operations of the closing lid 32 (for example, 1 hour increase / open operation count or 10% increase / open operation count). The odor component adsorbed in a large amount can be sufficiently desorbed by the length of the predetermined regeneration period, and the regeneration of the adsorption deodorization unit 36 can be completed with certainty. In other words, the smaller the number of times the opening lid 32 is opened during the drying process, the more energy saving and lower noise of the suction means 44 can be achieved.

  Thereafter, the drying of the garbage progresses, and in the latter half of the drying when the generation of steam is reduced, the air temperature of the garbage processing container 21 and the hot air temperature ejected from the hot air outlet 29 are reduced by the amount of heat required for evaporation. Rises. 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. However, even if the garbage drying process is completed during the predetermined regeneration period, the control unit continues the driving of the suction means 44 until the predetermined regeneration period elapses to complete the regeneration of the adsorption deodorizing unit 36. That is, the adsorption deodorization unit 36 can adsorb the peak odor component again.

  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. 1 is a front cross-sectional view showing a cross-sectional configuration taken along the line AA in FIG. 3 of a garbage disposal apparatus according to Embodiment 2 of the present invention, and FIG. 2 is a diagram of the garbage disposal apparatus in FIG. FIG. 3 is a right side cross-sectional view showing the BB cross-sectional structure in FIG. 1 of the garbage disposal apparatus, and FIG. 4 is a CC cross-sectional view in FIG. 1 of the garbage disposal apparatus. FIG. 5 is a left side cross-sectional view showing a cross-sectional configuration, FIG. 5 is a timing chart for putting garbage into the first half of drying, FIG. 6 is a temperature / concentration characteristic depending on drying time, and FIG.

  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 predetermined period of regeneration is 9 hours for the opening operation of the charging lid 43 from the start of the operation of the heating means 45 to 4 hours, and the opening of the charging lid after 4 hours from the start of the operation of the heating means 45. The point of operation is to set it as short as 4 hours.

  As shown in FIG. 6, during the first half of drying from the start of operation of the heating means 45 to the first half of the drying period, the generation amount of steam containing odorous components increases as the temperature of the garbage by the heating means 45 increases. The odor component concentration in the container 21 is high. Subsequently, in the latter half of the drying after 4 hours from the start of the operation of the heating means 45, the amount of steam in the garbage is reduced because the amount of moisture in the garbage is reduced, and the condensation deodorizing means is reduced to steam, odor. Since the components and heat are removed, the odor component concentration in the garbage disposal container 21 is low.

  Therefore, as shown in FIG. 5, when the charging lid 43 is opened during the first half of drying from the start of the operation of the heating means 45 having a high odor component concentration in the garbage disposal container 21, the adsorption deodorizing unit 36 causes a large amount of odor. Since the components are adsorbed, the adsorption / deodorization unit 36 does not complete the regeneration by desorption unless the predetermined regeneration period is set long. On the other hand, as shown in FIG. 8, when the charging lid 43 is opened in the latter half of the drying after 4 hours from the start of the operation of the heating means 45 having a low odor component concentration in the garbage processing container 21, the adsorption / deodorization unit 36 will cause too little odor component. Therefore, the adsorption / deodorization unit 36 can complete the regeneration by desorption within a short regeneration predetermined period. In other words, in the latter half of the drying, since the predetermined regeneration period is short, the driving time of the suction means is short, so that energy saving and noise reduction can be achieved.

  Note that the same effect can be obtained by reducing the suction capability of the suction means 44 instead of shortening the predetermined regeneration period. Further, the period between the first half and the second half of the drying is affected by the amount of garbage, the composition of the garbage, the amount of heating of the heating unit 46, and so on, and therefore correction may be necessary.

(Embodiment 3)
A garbage disposal apparatus according to Embodiment 3 of the present invention will be described with reference to FIGS. FIG. 1 is a front cross-sectional view showing a cross-sectional configuration taken along the line AA in FIG. 3 of a garbage disposal apparatus according to Embodiment 3 of the present invention, and FIG. 2 is a view of the garbage disposal apparatus in FIG. FIG. 3 is a right side cross-sectional view showing the BB cross-sectional structure in FIG. 1 of the garbage disposal apparatus, and FIG. 4 is a CC cross-sectional view in FIG. 1 of the garbage disposal apparatus. FIG. 9 is a left side cross-sectional view showing a cross-sectional configuration, FIG. 9 is a timing chart for charging garbage in the first half of drying, and FIG. 10 is a timing chart for charging garbage in the second half of drying.

  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 suction unit 44 stops driving when the heating unit 45 finishes heating due to the end of drying of garbage even during the predetermined period of regeneration.

  As shown in FIG. 9, in the first half of drying from the start of the operation of the heating means 45, when the open lid 43 is opened and the garbage is thrown in, the adsorption deodorization unit 36 adsorbs a large amount of the rich odor component, The regeneration of the adsorption / deodorization unit 36 is forcibly terminated when the garbage is dried, but a long regeneration time can be secured.

  As shown in FIG. 10, on the contrary, in the latter half of the drying after 4 hours from the start of the operation of the heating means 45, when the input lid 43 is opened and the garbage is thrown in, the adsorption / deodorization unit 36 adsorbs a small amount of a thin odor component. Therefore, the playback time may be short. In either case, the regeneration predetermined period has not elapsed at the stage where the garbage has been dried, but the adsorption and deodorization unit 36 has almost completely regenerated.

  Then, when the garbage is thrown in again, the regeneration of the adsorption / deodorization unit 36 is resumed with the start of the operation of the heating means 45. For this reason, since the peak odor component concentration is set at the worst conditions such as foods that easily generate odor components and a large amount of garbage during the predetermined period of normal regeneration, there is very little problem of odor in actual use.

(Embodiment 4)
A garbage disposal apparatus according to Embodiment 4 of the present invention will be described with reference to FIGS. FIG. 1 is a front cross-sectional view showing a cross-sectional configuration taken along the line AA in FIG. 3 of a garbage disposal apparatus according to Embodiment 3 of the present invention, and FIG. 2 is a view of the garbage disposal apparatus in FIG. FIG. 3 is a right side cross-sectional view showing the BB cross-sectional structure in FIG. 1 of the garbage disposal apparatus, and FIG. 4 is a CC cross-sectional view in FIG. 1 of the garbage disposal apparatus. FIG. 11 shows a four-day timing chart.

  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 if the lid opening / closing detection unit 35 has not detected the opening operation of the closing lid 43 for two days, the control unit drives the opening / closing means 63 to open the communication passage 62 and the suction means. A point 44 is driven for a predetermined period for absence. For the predetermined period for absence, one hour is sufficient, and generally about 20 minutes.

  If the lid opening / closing detection unit 35 has not detected the opening operation of the closing lid 43 for two days, it is determined that the user is absent. Then, the controller drives the opening / closing means 63 at predetermined intervals (12 to 36 hours) to open the communication passage 62, and the suction means 44 is driven for a predetermined period for absence. Is appropriately dehumidified by external air sucked by the suction means, and dust is discharged. Subsequently, the control unit drives the opening / closing means 63 to close the communication passage 62. As a result, the adsorption and deodorization part is always hygienic because the growth of mold and fungi is suppressed.

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.
