Abstract

PROBLEM TO BE SOLVED: To reduce the amount of drainage entering a decomposition tank in a garbage treatment apparatus into which garbage is charged from the drain hole of a sink. SOLUTION: An aqueduct installed above a sink 2 is used. When drainage is generated, depending on the position of the faucet of the aqueduct, usually as shown by an arrow, the drainage flows from a position outside the opening fringe part of a drainage hole 3 toward the opening fringe part into the drainage hole 3. Most of the drainage, as shown by an arrow, flows into an outside drain part and is prevented from flowing further to the inside by a ring-shaped part. In this process, relatively large foreign matters in the drainage which cannot pass through a drain hole by a drain board is checked, and only water passes through the drain hole and flows into a drainage passage 8. The drainage j' passed through the drain hole is guided to flow toward the outside of a transfer passage 5 by a guide plate.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage processing apparatus for decomposing garbage generated in a kitchen, a kitchen, and the like, and is particularly suitable for a garbage processing apparatus disposed below a sink. .

[0002]

2. Description of the Related Art As a garbage disposal apparatus as described above, there is an apparatus described in Japanese Patent Application Laid-Open No. 10-442.
In this system, a garbage disposal device is arranged below the sink, and the drainage hole provided at the bottom of the sink communicates with the garbage input port, so that garbage generated by water work can be easily generated. The garbage is transported in a garbage disposal device (a decomposition tank containing a microorganism carrier that decomposes garbage).

[0003] Specifically, the above-mentioned garbage input port is opened and closed by an opening / closing gate, and when processing garbage,
By opening the input port by operating the opening / closing gate, garbage is transferred to the decomposition tank. In addition, a drainage channel communicating with the drainage hole and discharging drainage entering from the drainage hole to the sewer pipe is provided at an outer peripheral portion of the transfer path.

[0004]

However, in the above-mentioned conventional apparatus, when, for example, water work is performed with the opening / closing gate being open, the drainage enters the decomposition tank through the drainage port of the sink through the drainage port. . As a result, there is a problem that the water content of the microorganism carrier is increased, the ventilation for keeping the microorganisms alive is not performed well, and the ability to decompose garbage is reduced.

[0005] Therefore, an object of the present invention is to reduce the amount of wastewater entering a decomposition tank in a garbage disposal apparatus for introducing garbage through a drain hole of a sink.

[0006]

In order to achieve the above object, according to the first to third aspects of the present invention, a guide for guiding drainage entering from near the opening edge of the drainage hole (3) to the drainage channel (8). A member (49) is provided. Thereby, since the drainage is guided by the guide member so as to flow toward the outside of the transfer path, even when the transfer path opening / closing means opens the transfer path, it is possible to reduce the drainage from entering the transfer path. As a result, the amount of wastewater that enters the decomposition tank can be reduced.

According to the second aspect of the present invention, the drainage channel (8) is provided over the entire area along the outer shape of the transfer path (5), and the guide member (49) is provided in the transfer path (5).
The guide member (49) is characterized in that its diameter is enlarged such that its lower end is located outside the upper end.
Accordingly, since the guide member has a shape whose diameter is enlarged such that the lower end portion thereof is located outside the upper end portion of the transfer path, the drainage can be guided to the outside of the transfer path. Similar effects can be obtained.

According to the third aspect of the present invention, the drain hole (3) includes an outer drain portion (4a) having a plurality of drain holes in the guide member (49) and an inner drain portion having a plurality of drain holes. (4b), and has an annular portion (50) protruding and extending above the bottom of the outer drainer (4a) and the bottom of the inner drainer (4b).

Thus, the drainage flowing toward the outer drainage portion can be reliably prevented from flowing into the inner drainage portion by the annular portion, so that the drainage can further be prevented from flowing into the transfer passage.

5 is provided with a temperature control heater 22 for controlling the temperature of the microorganism carrier 31 in the sample 5 to a predetermined temperature (about 50 ° C.). The heat generated by the temperature control heater 22 is transmitted to the inside of the microorganism container 15 by the fan 23 between the microorganism container 15 and the outer container 32. FIG.
Inside, the flow of air by the fan 23 is indicated by an arrow A.
In the microorganism container 15, a temperature sensor (not shown) for detecting the temperature of the microorganism carrier 31 is provided.
The control device 100 shown in FIG. 1 controls the temperature detected by the temperature sensor to be the predetermined temperature.

In FIG. 1, reference numeral 33 denotes a heat insulating layer for preventing the heat of the microorganism carrier 31 from escaping to the outside. In the present embodiment, the heat insulating layer is made of styrene foam adhered to the outer surface of the outer container 32. ing. The disassembly unit 14
A ventilation pump 24 is provided above the air conditioner. The suction port of the ventilation pump 24 communicates with the inside of the microorganism container 15. On the other hand, a ventilation pipe 25 made of stainless steel is connected to a discharge port of the ventilation pump 24. The downstream part of the ventilation pipe 25 is connected to the discharge pipe 9. The ventilation pump 24 discharges a decomposition gas generated when the garbage is decomposed in the microorganism container 15 through the discharge pipe 9 to the outside of the garbage processing apparatus 1, that is, to the sewage pipe 26.

The ventilation pump 24 and the temperature control heater 2
2 is configured to always operate when power is supplied from the power supply to the garbage processing apparatus 1, that is, when the outlet is plugged in. And the above-mentioned garbage processing apparatus 1 is configured to automatically perform garbage processing by the control device 100 shown in FIG. Hereinafter, the process of processing garbage by the control device 100 will be briefly described in order.

First, as the garbage accumulates in the draining part 4, the moisture in the garbage naturally flows out to the drainage channel 8 from a plurality of small holes formed in the draining part 4. , Garbage is drained. Then, when the user processes the garbage deposited in the draining section 4, when the foot pedal is first depressed, the opening / closing gate 7 operates and the input port 6 is opened. At this time, the draining part 4 is removed upward, and the garbage in the draining part 4 is put into the crushing part 11 through the transfer path 5 from the inlet 6. Subsequently, the foot is released from the foot pedal, and the opening 6 is closed by the opening / closing gate 7.

Then, the control device 100 controls the open / close gate 7
Determines that the input port 6 has been changed from the opened state to the closed state, and automatically drives the grinding motor 13 of the grinding unit 11 to rotate for a predetermined time (30 seconds). In addition, this open / close gate 7
Open / closed state is detected by a switch element (not shown). When the foot pedal is operated again during the 30 seconds, the crushing motor 13 is stopped.

Then, the garbage is finely crushed by the crushing blade 12, and the crushed garbage is transported by the impeller 30 so as to be blown to the left side in FIG. Subsequently, the grinding motor 13
Is operated for 2 minutes, the stirring motor 20 is automatically operated for 2 minutes, and the stirring blade 18 rotates. Thereby, the garbage sent into the microorganism container 15 and the microorganism carrier 31 are stirred. It should be noted that this stirring motor 20 can be used as described above even if the foot pedal is not depressed as described above.
It operates for two minutes every hour, and also operates when the foot pedal is operated in this manner.

Then, the decomposition gas generated in the decomposition is discharged to a drain 26 by a ventilation pump 24. When the garbage disposal device 1 is not used, the wastewater is sent from the discharge passage 9 located on the right side in FIG. Next, the details of the structure in the vicinity of the drainer 4 which is a main part of the present invention will be described. FIG. 2 shows a detailed view of the drainer 4.

An attachment (attachment member) 40 for attaching the drainer 4 is fitted in the drain hole 3. The attachment 40 is formed in an annular shape from, for example, a resin material such as polypropylene, and has an upper end portion serving as a retaining flange portion 41 extending in a substantially horizontal direction. A packing 42 (rubber material) for preventing leakage of water from the drain hole 3 is interposed between the flange portion 41 and the opening edge portion 3a in a compressed state.

The attachment 40 is firmly attached to the drain hole 3 as follows. Attachment 40 inserted into drainage hole 3 to a position below drainage hole 3
A male screw portion (not shown) is formed on the outer peripheral surface of the cylindrical portion 43 (the lower portion of the flange portion 42). Cylindrical part 43
An annular fastening portion 44, which is an attachment fastening member, is fitted into the outer peripheral portion of the device. That is, a female screw portion to be screwed with the male screw portion is formed on the inner peripheral surface of the tightening portion 44. By screwing the tightening portion 44, the flange portion 41 and the tightening portion 44 are connected. The opening edge 3a is sandwiched. Thereby, the attachment 40 is securely attached to the bottom of the sink 2.

The packing 42 is interposed between the flange 41 and the opening edge 3a. For this reason,
When the fastening portion 44 is tightened, the attachment 40
Is attached, and the packing 42 is crushed to be in a compressed state. As a result, the space between the flange portion 41 and the opening edge portion 3a is reliably sealed by the packing 42.

Below the cylindrical portion 43, a case portion 8a constituting the transfer path 8 is arranged. The cylindrical portion 43 and the case portion 8a are communicated and connected by a rubber material 45 (for example, chloroprene rubber, a communication connecting member). Specifically, a cylindrical rubber material 4 is provided on the outer peripheral portion of the lower end of the cylindrical portion 43.
The upper end of the case 5a is fitted in the lower end of the rubber material 45.

An inwardly protruding annular base portion 46 is formed integrally with the inner peripheral portion of the cylindrical portion 43, and this base portion 46 serves as a base for the draining unit 4.
The drainer 4 has a circular shape and has a guide member 49 described later.
The outer drainer 4a is roughly divided into an annular outer drainer 4a and an inner drainer 4b fitted in the outer drainer 4a.

The outer drainer 4a has a plurality of drain holes 60.
It has a metal drainer plate 47 in which (outside drain holes) are formed. In this example, the draining plate 47 is made of stainless steel, which is a metal having excellent corrosion resistance, and is formed in an annular shape having an L-shaped cross section (see FIG. 2). At an upper end portion of the draining plate 47, a holding portion 48 formed in an annular shape with resin (polypropylene) is formed. The holding portion 48 is for holding the outer draining portion 4a in contact with the upper surface of the base portion 46. The draining plate 47 is formed of the resinous holding portion 4.
8 is cast.

A guide portion 49 is formed on the inner peripheral side of the annular draining plate 47. The guide portion 49 is made of resin (polypropylene) in this example, and has an annular shape along the outer shape of the upper end of the transfer path 5. The draining plate 47 is cast into the guide 49 and is integrated therewith. As shown in FIG.
Has an annular portion 50 extending above the lowermost portion (bottom portion) of
Thus, the outer drainer 4a has a U-shaped section in cooperation with the drainer 47 and the annular portion 50.
That is, the annular portion 50 extends so as to protrude above the bottom of the outer drainer 4a and the bottom of the inner drainer 4b,
The drain hole 3 is partitioned into an outer drainer 60 and an inner drainer 61.

The guide portion 49 is formed integrally with a guide plate 51 extending further downward from the lower end of the annular portion 50. The guide plate 51 (guide portion 49) has a shape whose diameter is enlarged such that the lower end portion is located outside the upper end portion (input port 6) of the transfer path 5. The inner drainer 4b has a metal drainer plate 52 in which a plurality of drainers 61 (hereinafter, inner drain holes) are formed. Drainer 5
Reference numeral 2 denotes stainless steel, which is a metal having excellent corrosion resistance in this example, and is formed in a circular dish shape. At an upper end portion of the draining plate 52, a holding portion 53 formed in an annular shape with resin (polypropylene) is formed. The draining plate 52
Is cast in the resin holding portion 52.

The holding portion 53 contacts the upper end surface of the annular portion 50 and holds the installation position of the inner draining portion 4b. That is, after the attachment 40 is attached to the drain hole 3, the inner drainage part 4 b is inserted and arranged inside the outer drainage part 4 a downward from above.
With such a configuration, in the present example, the inner lower portion of the drain hole 3 has a double structure in which the above-described outer drain portion 4a and inner drain portion 4b are formed by the guide portion 49.

Next, the flow of drainage generated in the sink 2 will be described. For example, when drainage is generated by using a water supply installed above the sink 2, it usually depends on the position of the tap, but as shown by an arrow in FIG.
Flows into the drainage hole 3 from a portion outside the opening edge 3a toward the opening edge 3a. At this time, the draining board 4
At 7, relatively large foreign substances in the drainage that do not pass through the drain hole 60 are dammed, and only water passes through the drain hole 60,
It flows into the discharge path 8. The drainage that has passed through the drain hole 60 is
The guide plate 51 guides the flow toward the outside of the transfer path 5 so that even when the opening / closing gate 7 is open, it is possible to surely prevent the drainage from entering the transfer path 5. As a result, intrusion of drainage into the microorganism container 15 can be reduced.

Most of the drainage flowing from the opening edge 3a surely flows into the outer drainer 4a by the annular portion 50 as shown by the arrow in the figure, and the outer drainer 4a
The drainage that has flowed into the inside
It does not flow into b). As a result, therefore, it becomes more difficult for the wastewater to enter the transfer path 5, and the intrusion of the wastewater into the microorganism container 15 can be further reduced.
