The inside of a is heated to a temperature suitable for garbage decomposition, and the inside of the drying tank 2b is heated to a temperature suitable for drying the microorganism carrier 40 and the garbage decomposition residue.

The gate 8 is formed of a resin such as polypropylene into a spherical shape, and is disposed on the outer wall surface of the passage forming member 9 via a pair of gate posts 10 integrally formed with the gate 8. It is rotatably supported by a pair of gate rotation shafts 11. Gate rotation shaft 1 on the left in FIG.

Next, A is a pipe forming an intake passage for supplying air into the garbage processing tank 2, and the pipe A is a space in the kitchen cabinet below the sink 3 and the inside of the garbage processing tank 2 (where the collection container 41 is Communicates with the (upper) space in which it is mounted. On the other hand, B is a pipe forming an exhaust passage for discharging gas (decomposed gas or water vapor generated by decomposition of garbage) in the garbage processing tank 2, and the pipe B connects the upper space in the decomposition tank 2 a with the outside. Communicating.

The pipe B is provided with a deodorizer 61 which is a deodorizing means for removing odor components from the gas passing through the pipe B. In the present embodiment, a thermocatalytic high-temperature deodorizer that oxidizes and decomposes odor components at a high temperature is used as the deodorizer 61. This type of deodorizer is excellent in deodorization performance, but has a relatively large ventilation resistance, so that pressure loss is likely to occur around the deodorizer 61.

Next, the upstream side and the downstream side of the deodorizer 61 pass through the heat exchanger 62, and exchange heat between the gas heated by the deodorizer 61 and the gas flowing into the deodorizer 61. The energy required for gas heating at the time of deodorization by the deodorizer 61 is reduced. Here, as the heat exchanger 62, a double-pipe countercurrent heat exchanger is used.

On the downstream side of the heat exchanger 62, a pipe B
An electric fan 63 for feeding the air in the chamber to the downstream side is provided. Here, an electric fan of a type that drives a sirocco fan with an electric motor is used as the electric fan 63. When the electric fan 63 operates, air is supplied into the garbage disposal tank 2 through the pipe A, and gas in the garbage disposal tank 2 is discharged through the pipe B. Therefore,
The electric fan 63 is a ventilation fan serving as ventilation means.

A pipe C that connects the inside of the kitchen cabinet and the inside of the pipe B is connected to the upstream side of the electric fan 63. When the deodorizer 61 and the electric fan 63 are operated, the gas heated at the time of deodorization and cooled by the heat exchanger 62 and the air sucked in through the pipe C are located downstream of the connection point between the pipes B and C. And a gas mixed with. Therefore, a gas having a lower temperature than the gas flowing out of the heat exchanger 62 flows, so that it is possible to reduce the influence of heat on the electric fan 63 and piping components downstream therefrom.

Next, on the downstream side of the electric fan 63, a recirculation pipe 67, one of which is connected to communicate with the input port 7, and an exhaust pipe 68, which is connected so that the other communicates outdoors, are branched. It is provided. The return pipe 67 has a first electromagnetic valve 65 as a first opening / closing means for communicating or blocking this path, and the exhaust pipe 68 has a second electromagnetic valve as a second opening / closing means for communicating or blocking this path. Valve 66
Is provided. The reflux pipe 67 is a passage for refluxing the deodorized gas into the garbage decomposition tank 2 through the inlet 7.
The exhaust pipe 68 is a passage for exhausting the deodorized gas to the outside.

Here, the downstream end of the return pipe 67 is
As shown in (a), it is connected via a connecting member 9d to an intake portion 9a arranged on the outer wall surface of the passage forming member 9. On the inner peripheral side of the passage forming member 9, an inner cylindrical portion 9 c having a plurality of openings 9 b is provided with an airtight gap between the outer periphery of the inner cylindrical portion 9 c and the inner periphery of the passage forming member 9. Part 9
It is arranged to form d.

As a result, the reflux pipe 67 communicates with the inlet 7, and the deodorized gas taken in from the inlet 9a passes through the gap 9d and the opening 9b into the inlet 7 and the decomposition tank 2.
The liquid is returned into the transfer path 6 between the first and second transfer paths.
The plurality of openings 9b have a predetermined opening area in the cylindrical portion of the inner cylindrical portion 9c, and are set so as to blow out substantially uniformly into the transfer path 6.

Reference numeral 22 denotes a control device which is a control means. The control device 22 controls the stirring motor 5 based on input signals from the limit switch 20, the water content sensor 42 and the like.
3. It is configured to control the deodorizer 61, the electric fan 63, the first and second electromagnetic valves 65 and 66, and a planar heater (not shown).

Next, the garbage disposal apparatus 1 based on the above configuration
The operation of will be described.

The garbage is poured from the drain port 4 of the sink 3,
As the garbage accumulates in the draining part 5, the water in the garbage naturally flows out from the plurality of small holes formed in the draining part 5 to the discharge path 12, and the garbage is drained. Done. At this time, the gate 8 is in the closed position Y and the drain 4
And the opening 7 are shut off. The water flowing out of the discharge passage 12 is sent to a drain pipe 14 through a drain trap 13.

When the user wants to dispose of the garbage deposited in the draining section 5, first, the gate 8 is turned from the closed position Y to the open position X, and the inlet 7 is opened. .

Next, the drainer 5 is removed upward,
The garbage in the draining section 5 is sent from the input port 7 to the decomposition tank 2a through the transfer path 6. After the garbage is sent to the decomposition tank 2a, the gate 8 is turned from the open position X to the closed position Y, and the space between the drain port 4 and the charging port 7 is shut off.

In the decomposition tank 2a, the stirring blade 50 is rotated to stir the garbage sent into the decomposition tank 2a and the microorganism carrier 40 in the decomposition tank 2a. Thereby, the garbage is decomposed by the microorganisms in the microorganism carrier 40 into decomposed gas and decomposed water. When the garbage decomposition residue in the decomposition tank 2a increases and a part of the microorganism carrier 40 and the garbage decomposition residue falls into the drying tank 2b, these are mixed with the stirring blades 5 in the drying tank 2b.
After being dried by rotation of 5, it is sent to the collection container 41.

Here, the control operation of the control device 22 is shown in FIG.
This will be described with reference to the flowchart shown in FIG. When the power of the garbage disposal device 1 is turned on, the control device 22 first energizes the deodorizer 61, the electric fan 63, and the heater (not shown) (step 100), and the gate 8 opens the X position.
(Step 110), the terminal 20a of the limit switch 20 and the terminal 20b of the limit switch 20 are brought into contact by the driving piece 21 so that the limit switch 20 is turned on. In some cases, the control device 22 that has received the ON signal causes the electric fan 6
The rotation speed of the third electromagnetic valve is set to the Hi level, and the first electromagnetic valve 65 is opened and the second electromagnetic valve 66 is closed (step 120).

As a result, air is supplied into the garbage disposal tank 2 from the pipe A and the inlet 7, and the gas in the garbage disposal tank 2 is deodorized by the deodorizer 61 provided in the pipe B. The air is blown into the transfer path 6 from the opening 9b via the return pipe 67, the intake section 9a and the gap 9d, and is returned to the garbage processing tank 2. The heater is the decomposition tank 2a.
And the drying tank 2b is heated.

Next, it is determined whether or not the gate 8 is at the closed position Y (step 130). When the gate 8 is at the closed position Y, that is, when the limit switch 20 is off, the first electromagnetic valve 65 is closed. The second electromagnetic valve 66 is opened (Step 140). As a result, air is supplied from the pipe A into the garbage processing tank 2, and gas in the garbage processing tank 2 is deodorized by the deodorizer 61 disposed on the pipe B, and is discharged outdoors via the exhaust pipe 66. Exhausted.

Note that this step 130 is equivalent to step 1
The process is also performed when it is determined in 10 that the gate 8 is not at the open position X, that is, when the gate 8 is at the closed position Y.

Next, when step 140 is executed, the control device 22 executes normal disassembly control (step 15).
0). When the normal disassembly control is performed, the control device 22
Controls the air flow level of the electric fan 63 based on the signal from the moisture content sensor 42. For example, if the moisture content is 4
When it is 0% or more, the rotation speed of the electric fan 63 is set to the Hi level, the steam in the decomposition tank 2a is quickly discharged, and the water content is reduced. When the water content is less than 40%, the rotation speed of the electric fan 63 is set to the Lo level.

The control device 22 is provided with a moisture content sensor 42.
The operating state of the stirring motor 53 is also controlled based on the signal from For example, when the water content is 50% or more, the stirring motor 53 is operated for 30 seconds every 15 minutes to frequently stir the microorganism carrier 40 in the decomposition tank 2a and the inputted garbage,
The water contained in the microorganism carrier 40 and the garbage is diffused as steam into the garbage processing tank 2 to facilitate discharge. When the water content is less than 30%, the stirring motor 53 is turned on every 30 minutes.
It operates for 2 seconds, and when the water content is 30% or more and less than 50%, the operation interval is changed according to the water content.

Further, the controller 22 controls the water content sensor 4
Based on the signal from the control unit 2, the power supply state of a heater (not shown) is also controlled. For example, when the water content is 50% or more, the heater is controlled to generate heat so that the temperature in the decomposition tank 2a is 60 ° C.
The water contained in the microorganism carrier 40 and the garbage in the decomposition tank 2a is easily evaporated. When the water content is less than 30%, the heater is controlled to generate heat so that the temperature in the decomposition tank 2a becomes 40 ° C., and when the water content is 30% or more and less than 50%, the temperature is controlled according to the water content.

Incidentally, the temperature of 60 ° C. is the upper limit temperature at which the bacteria carried on the microorganism carrier 40 do not die. This is the minimum temperature at which insects and the like do not occur. Therefore, at 40 ° C. to 60 ° C., the garbage is decomposed satisfactorily, and no insects appear in the decomposition tank 2a. Also, the heater (not shown) is set such that the temperature in the drying tank 2b is lower than the temperature in the decomposition tank 2a by 5 times.
The temperature is raised by about 10 ° C. to 10 ° C., so that the microorganism carrier 40 and the garbage decomposition residue in the drying tank 2b can always be dried.

After executing the normal disassembly control in step 150, the process returns to step 110.

According to the garbage processing apparatus 1 of the above embodiment, when the input port 7 is closed, the electric fan 63
, The introduction of external air through the pipe A and the deodorization and discharge of the gas in the garbage processing layer 2 through the pipe B and the exhaust pipe 68 are performed, and the inside of the garbage processing tank 2 is ventilated. . Thereby, the oxygen required for the decomposition of garbage is supplied into the garbage processing tank 2.

When the charging port 7 is opened for charging the garbage, the first electromagnetic valve 65 is opened and the second electromagnetic valve 66 is closed. While the air is supplied into the tank 2, the gas in the garbage processing tank 2 is deodorized by the deodorizer 61, and is transferred from the opening 9 b to the transfer path 6 through the reflux pipe 67, the intake 9 a and the gap 9 d. The gas in the garbage processing tank 2 can be exhausted by being blown out to the garbage processing tank 2 and being refluxed.

The deodorized gas blown out from the opening 9b into the transfer path 6 flows toward the garbage decomposition tank 2 due to the suction effect of the deodorized gas. The flow rate can be increased. Moreover, the ventilation capacity of the electric fan 63 at this time is compared with the ventilation capacity that can prevent the odor from leaking from the inlet 7 when the inlet 7 is opened while discharging the deodorized gas to the outside. Thus, the above suction effect can be reduced. As a result, even when a large electric fan having a large maximum ventilation capacity is not employed, it is possible to prevent the odor from rising from the inlet 7 and leaking into the kitchen when the garbage is charged.

Further, since the deodorized gas is recirculated from the plurality of openings 9b around the predetermined portion of the passage forming member 9, the odor in the garbage disposal tank 2 is injected by the effect of blocking the recirculated gas. Leakage from the mouth 7 can be reliably prevented.

(Other Embodiments) In the above embodiment,
An exhaust pipe 68 for discharging the deodorized gas to the outside and a second electromagnetic valve 6 for opening and closing the exhaust pipe 68 are provided downstream of the pipe B.
And a reflux pipe 6 for returning the deodorized gas into the inlet 7.
Although the opening and closing means for opening and closing the pipe 7 and the first electromagnetic valve 65 for opening and closing the return pipe 67 are provided in each of the pipes 67 and 68, switching for switching the flow direction to either the exhaust pipe 68 or the return pipe 67 is performed. It may be replaced with a switching valve as a means.

As shown in FIG. 4, a switching valve 65a is provided on the downstream side of the electric fan 63, that is, at a branch portion between the exhaust pipe 68 and the recirculation pipe 67, and when the gate 8 closes the input port 7, the switching valve 65a is switched. The control is performed so that the valve 65a discharges to the exhaust pipe 68 side, and when the gate 8 opens the inlet 7, the switching valve 65a controls to return to the return pipe 67 side.
Thereby, the two electromagnetic valves 6 of the above-described embodiment are provided.
The switching valve 65a has a smaller number of parts and can reduce the cost of parts than using the switching valves 65 and 66.

The garbage processing apparatus 1 is connected to a kitchen sink 3.
And an inlet 7 communicating with the drain 4 of the sink 3
Although the garbage is supplied more, the input port 7 may be provided outside the sink 3, or the garbage processing apparatus 1 may be installed other than below the sink 3. Further, it may be installed indoors other than the kitchen, or may be installed outdoors. However, a garbage disposal apparatus installed indoors including a kitchen has a greater effect of preventing discomfort of a user by preventing dirt, odor and the like according to the present invention.

In the above embodiment, the limit switch 20 is used to detect the open state of the gate 8, but another gate open / close detector such as a magnet switch may be used. Further, the gate opening / closing detector is attached at a position operated by the driving piece 21, but may be attached to a portion such as a foot pedal that interlocks with the gate. Further, the gate opening / closing detector is mounted at a position for detecting a state where the gate 8 fully opens the inlet 7, but may be mounted at a position for detecting an intermediate state between the gate open position X and the gate closed position Y. When the gate 8 is opened and closed by an electric switch and power, the gate opening / closing detector may detect the electric signal.

In each of the above embodiments, the electric fan 63 is used as the ventilation means, but an electric pump or the like may be used.

In each of the above embodiments, the reflux pipe 67,
Although the electromagnetic valves 65a, 65, and 66 are used as the opening / closing means or the switching means of the exhaust pipe 68, the electromagnetic valve is not limited to the electromagnetic valve as long as it can open or close or switch this passage. Alternatively, a switching door member may be provided, and the door member may be operated by the driving force of a servo motor.

In each of the above embodiments, the gate 8 has a spherical shape and is opened and closed by a rotating operation. However, if the gate 8 can shut off the space between the drain port 4 and the inlet port 7, the slide system may be used. Alternatively, another gate such as a desorption type may be used.
