Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposer capable of crushing and packing raw garbage associated with kitchen work such as cooking and washing.

[0002]

2. Description of the Related Art The processing of raw garbage generated during kitchen cooking, cleaning up, etc. is extremely important from the viewpoint of hygiene as well as generation of offensive odor. As a method for treating this garbage, a disposer that pulverizes the garbage and discharges it into a drainage pipe has been conventionally used.

However, since the water containing the garbage is discharged to the drainage pipe, the degree of pollution in the wastewater becomes high, and the suspended matter, BOD (biochemical oxygen demand) and COD in the wastewater are increased.
(Chemical oxygen demand) inevitably increases. For this reason,
In areas where sewers are not complete, types that discharge with water cannot be applied.

[0004] From such a background, a structure in which crushed raw garbage is packed in a polyethylene bag in a certain amount, instead of the structure in which the waste is discharged together with the drainage, is generally popular. An example of a disposer for carrying out this bag packing is disclosed in Japanese Utility Model Laid-Open No. 61-195355.

This disposer has a structure in which raw garbage is thrown into a crusher rotating at high speed, the crushed raw garbage is sent to a squeezing machine together with water, and the squeezed processed product is packed in a bag.

[0006] Further, in order to remove water from the crushed raw garbage and pack it in a bag, there is also one in which a rotor for centrifugal separation is provided to separate the water.

[0007]

However, since raw trash is crushed by a crusher immediately after it is fed, hard bones such as fish rise into powder particles and other raw trash is vigorously stirred inside. To be done. On the other hand, at the upper end of the crusher, only a rubber plate having slits is arranged instead of the lid, so that the offensive odor of raw garbage easily leaks from the inside of the crusher. Therefore, the offensive odor is dissipated in the kitchen,
Not suitable for kitchen equipment that requires cleanliness. Further, the emission of off-flavours is remarkable, especially when the centrifugal dehydration structure is used.

[0008] Further, it is also necessary to supply water to the inside to eliminate the residual processed material after the processing of the garbage is completed at the time of use. However, if you simply pour water,
The removal of fine dust is not sufficient, and as a result, raw dust is often left in the interior. In this case, it promotes the reproduction of mold fungi, which poses a serious problem in hygiene.

Therefore, an object of the present invention is to eliminate the emission of offensive odor in the process of treating food waste and prevent the generation of mold bacterium so that it can be used hygienically.

[0010]

In order to achieve the above-mentioned object, the present invention connects a cylindrical main body having an open upper end to the lower surface of a sink of a sink, and grinds raw garbage thrown into the main body. In the disposer having a mechanism for dewatering and bagging in the main body, a nozzle for spraying the sterilizing and deodorizing liquid in the main body is provided in association with the mechanism.

The discharge port 24 of the main body 4 to which the bend 25 is connected also has an opening shape elongated in the circumferential direction of the main body 4.

A stocker 26 containing vinyl V, which serves as a bag for receiving the discharged product, is detachably connected to the lower end of the bend 25. FIG. 6 shows a plan view of the stocker 26 portion. The stocker 26 is a tubular body having upper and lower ends having a rectangular opening cross section, and a sleeve 27 having an oval cross section is inserted therein. The sleeve 27 is integrated with the stocker 26, and vinyl V is stacked around the stocker 26 in a wavy state. Then, the stocker 26 can be freely taken out and put in from the attachment / detachment port 1c in which a part of the casing 1 is opened, and after the vinyl V is consumed, it is taken out from the casing 1, replenished, and set at a predetermined position again. use.

Further, in the sub-chamber 1b, a welding / melting device 28 for packing the processed material in vinyl V is arranged. The welding / fusing device 28 has a structure in which the forward / reverse rotation of the output shaft of the motor 29 is converted into a reciprocating linear motion by a screw gear mechanism or the like, and the thermal head 3 having a heated tip is used.

Further, in the sub-chamber 1b, a container 33 containing a deodorizing and sterilizing liquid is provided in order to mitigate the offensive odor generated during the processing time, and these liquids are supplied in synchronization with the operation of the disposer. Supply into the main body 4. As the container 33, a generally used one such as an aero nozzle system can be used, and a slider 34 for opening and closing the flow path is provided at the upper end. A hose 35 is connected to the slider 34, and the main body 4
The hose 35 is connected to a nozzle 36 for injecting a deodorizing / sterilizing liquid from the upper side of the. Further, the pusher 37 is attached to the thermal head 30 that reciprocates by the operation of the motor 29.
Is provided, and the pusher 37 moves the slider 34 to open the flow path from the container 33. By opening this flow path,
The deodorizing and disinfecting liquid inside the container 33 is ejected from the nozzle 36 in a spray state, and the offensive odor generated in the main body 4 can be removed and disinfecting. In addition, in order to replace the container 33, the casing 1 on the side of the sub chamber 1b is partially opened and closed. Further, as the disinfecting liquid, for example, a cationic bactericide can be used, and as the deodorizing liquid, a flavonoid stock solution or the like is used. Therefore, it suffices to put a mixture of these in the container 33, and in addition, bacteria, yeast, etc. can be used.

Further, the drive motor 5 and the welding / fusing device 2
The operation of the motor 29 of No. 8 is performed by an operation panel (not shown) provided on the front surface of the cabinet or the like. A control circuit is provided so that operations such as crushing, dehydration, and filling of vinyl V with time can be associated in time.

With the above-mentioned arrangement of each member and each function, raw garbage is treated in the following manner.

First, the garbage is removed from above the cover 7 into the main body 4.
When the operation panel is powered on after being put in, the drive motor 5 operates and the output shaft 5a thereof rotates. The rotation direction of the output shaft 5a is clockwise in FIG. 4A during the initial period.

The rotation of the output shaft 5a is transmitted to the spindle 13 so that both the dehydration rotor 10 and the rotary plate 16 rotate at high speed. By the rotation of the rotary plate 16, the raw dust put in the main body 4 is crushed by the crushing teeth 8 and the crusher teeth 17 rotating at high speed. Then, by the high speed rotation of the rotary plate 16, the crushed raw garbage is moved toward the crushing tooth 8 by the centrifugal force, and falls from the gap between the rotary plate 16 and the crushing tooth 8. The processing material that dropped
Guided by the guide 23, it slides down to the center side, falls to the center of the bottom of the dehydration rotor 10, and shifts to the dehydration process by centrifugal force.

The processing material in the dewatering rotor 10 receives the centrifugal force due to the high speed rotation, and moves up the diagonal wall surface,
Solid water separation is performed. That is, water is discharged from the dehydration slit 20 by the centrifugal force, and only the solid portion of the treatment material remains inside. Then, the discharged water is drained 11
Sent to general drainage pipes for disposal.

In the dehydration process by the dehydration rotor 10,
The rotation direction is clockwise in FIG. 4A, and the twist angle of the blade 22 is positive in the rotation direction. Therefore, these blades 22 act as a baffle plate for the processing material rising on the inclined wall surface. Further, since the dehydration rotor 10 rotates at a considerably high speed, as described above,
The blades 22 supply air into the spin-drying rotor 10 like an axial-flow fan, and the internal pressure rises slightly. Therefore, the treatment material stays in the lower portion of the blade 22, and the dehydration by the centrifugal force is further promoted.

Then, after a certain period of time, the rotation direction of the output shaft 5a of the drive motor 5 is reversed. Of course, such control is automatically performed. By the reverse rotation of the output shaft 5a, the twist angle of the blade 22 becomes negative with respect to the rotation direction, and the processing material retained in the lower portion thereof is cut into pieces. As a result, the processing material is cut out from the waste port 21 using the blades 22 as guides and sent from the discharge port 24 into the bend 25. As described above, the high-speed rotation of the blades 22 accelerates the air flow from the dehydration rotor 10 to the outside and reduces the internal pressure, so that the processing material is smoothly discharged.

When the above-mentioned crushing and dehydration processes are completed and the treated material is completely discharged into the vinyl V, the drive motor 5 stops its operation in time. Then, in order to make the vinyl V into a bag, the motor 29 is operated and the welding / fusion device 28 is operated. In this process, the thermal head 30 is moved in the direction of the vinyl V by the operation of the motor 29 to be melted and fused at the same time, and the processing material can be enclosed in the vinyl V and discarded.

Simultaneously with the fusing and welding of the vinyl V, the disinfecting and deodorizing material is sprayed from the nozzle 36 on the upper side of the main body 4. That is, when the motor 29 operates, the pusher 37
As a result, the slider 34 moves, and the deodorizing and sterilizing liquids in the container 33 are mixed and supplied from the hose 35 to the nozzle 36. These liquids are ejected from the nozzle 36 into the main body 4.

As described above, since the deodorizing and sterilizing liquid is sprayed from above the crushing mechanism portion such as the crusher teeth 17 provided inside the main body 4, the offensive odor generated during the processing of the garbage is deodorized. .. Therefore, even when the garbage is processed in parallel with cooking, there is no emission of offensive odor in the kitchen, and it is possible to comfortably cook and eat. In addition to this, since the sterilization liquid is also sprayed, the decay of the retained processed material remaining in the main body 4 after the disposal of the processed material and the generation of mold are effectively prevented. Therefore, the disposer can always be kept hygienic and the atmosphere in the kitchen can be kept clean.

In the above embodiment, the sterilization and deodorization are performed after the garbage treatment, but this can be performed at various timings such as before and during the treatment.
