Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a self-cleaning device for a kitchen waste disposal machine that crushes, dehydrates, and discharges kitchen waste dumped from a waste dumping port in a sink.

Conventionally, in unit type sinks, a part of the sink is equipped with a garbage disposal port that also serves as drainage, and a garbage receptacle for draining, such as a dehydration basket, is installed at the bottom of the garbage disposal port, and an elastic body installed in the garbage disposal port To counter this, there was a system in which kitchen waste was dumped in a closet, but the kitchen waste that had accumulated in the garbage receptacle had to be taken out and disposed of, which was dirty, emitted a foul odor, was unhygienic, and the process was difficult. It was a hassle.

Therefore, in recent years, especially in crowded facilities, kitchen waste disposal machines (disposers), which pulverize the kitchen waste and discharge it into the sewer along with the waste water, have been used to dispose of the kitchen waste that is dumped from the waste disposal port of the sink. It started to appear. However, in this case, the effluent becomes extremely polluted and may violate effluent water BOD regulations, etc. Furthermore, the discharged kitchen waste will generate putrid odor and other bad odors from the sewage, making it unnecessary to treat the sewage. There were various administrative problems. Therefore, recently, the kitchen waste dumped from the garbage dumping port of the sink is crushed in a crushing chamber, the crushed material is sent to the outside of the lower part of the crushing chamber to be dehydrated, and the dehydrated material is placed in a casing.
It has been considered to dispose of kitchen waste without discharging it into sewage by discharging it from the outlet of the kitchen waste and storing it in a kitchen waste storage container, etc., and the present inventor has also proposed a method for disposing of kitchen waste using the above-mentioned method. The processing machine is equipped with an inverted truncated cone-shaped dewatering basket outside the wall of the crushing chamber inside the casing, and equipped with blades that can rotate along the inner circumference of the dewatering basket.
It is an object of the present invention to provide a device in which crushed kitchen waste sent out from a crushing chamber is rotated in a dewatering basket by rotating blades and discharged from a discharge port above the dehydrating basket by the centrifugal force. In the above-mentioned kitchen waste disposal machine, the kitchen waste discharged from the discharge port and stored in the kitchen waste storage container or bag body can be disposed of before a bad odor occurs. If it remains, problems such as putrid odor and other bad odors will be generated and radiated into the kitchen, and the impact will be great. Therefore, it is necessary to leave as little kitchen waste as possible inside the casing.
Normally, almost all of the shredded kitchen waste can be discharged by increasing the amount of water flowing during kitchen waste treatment, but the amount of water cannot be increased too much in order to save water. Therefore, the non-operating parts of the casing, such as the outer peripheral surface of the dehydrator where drainage holes are formed, and the inner peripheral surface of the casing, where the drainage is soft, tend to attract fine kitchen waste and slag that gets mixed into the drainage. Once adhered, it is difficult to remove, and this is one of the causes of putrid odor coming from inside the casing.
Particularly on the outer circumferential surface of the dewatering basket, fine kitchen waste and the like tend to adhere around the drain hole, and if this is left untreated, there is a risk that the adhered substances will solidify and gradually increase, eventually leading to clogging. In view of the above, the present invention provides a scraping member that can come into contact with both surfaces or one surface between the outer circumferential surface of the dewatering basket and the inner circumferential surface of the outer casing, and the scraping member is synchronized with a rotary disk. By rotating the dewatering basket, kitchen waste and the like adhering to the outer peripheral surface of the dewatering basket and the inner peripheral surface of the casing can be removed at the same time as the kitchen waste is processed.

Next, embodiments of the present invention will be described based on the drawings.

1 is a sink, 2 is a garbage dumping port that also serves as the drain of the sink, and 3 is a flange attached to the opening of the sink 1 to form the garbage dumping port 2. Inside the cylindrical portion 3a of the flange 3 is a knob 4. A drain plug 6 having a water outlet 5 that can be opened and closed by manual operation is detachably attached.

7 is the casing of the kitchen waste disposal machine, and 8 is the garbage dumping port! A crushing chamber 8 is provided below the dumping port 2 to crush the kitchen waste dumped from the casing 7. It is constituted by a wall 10.

In the case of the figure, the chamber wall 10 is made of a cylindrical body having a bent flange portion 10a at the upper end, and the flange portion 10a is fixed to the ceiling surface of the casing 7 with screws 11 or the like. At the bottom of the crushing chamber 8, there is a rotary disk 1 which also serves as the bottom of the chamber and is rotated around the axis of the crushing chamber 8 by a motor 12 outside the casing.
It has 3. Further, a fixed blade 14 is provided at the lower inner circumference of the chamber wall 10, and two striking blades 15, 15 corresponding to the fixed blade 14 are provided on the rotary disk 13.
The kitchen waste dumped into the crushing chamber 8 can be crushed by the rotation of the impact blades 15, 15 accompanying the rotation of the crushing chamber 8.
Further, a slight gap is provided between the peripheral edge of the rotary disk 13 and the lower end of the chamber wall 10, so that the crushed kitchen waste can be delivered and drained through the gap. In particular, the peripheral edge of the rotary disk 13 is slightly inclined outward at required points to facilitate the delivery and drainage of crushed kitchen waste. Reference numeral 16 denotes an inverted truncated cone-shaped dewatering basket provided outside the chamber wall 10 and rotary disk 13 of the crushing chamber 8; It consists of a perforated part 16a and a non-perforated part 16b of the upper half, and the upper end edge 16c is clamped and fixed by the upper body 7a and lower body 7b of the casing 7.

A blade 18 is equipped to rotate along the inner periphery of the dewatering basket 16, and is connected to blade support members 19 erected at several points around the periphery of the rotary disk 13. The shredded kitchen waste sent out from the rotor is rotated by the rotation of the blades 18.

Each blade support part 19 is connected by a ring 20 at its upper end. The ring 20 has a generally curved cross section corresponding to the flange portion 10a of the chamber wall 10. Reference numeral 21 denotes a discharge port opened on the upper side surface of the dewatering basket 16 in the casing 7, and is provided to discharge crushed kitchen waste that gradually moves upward while rotating inside the dehydrating basket 16 due to the rotation of the blades 18. There is. At the outer end of the discharge port 21, a synthetic resin storage container or bag (none of which is shown) or the like is removably attached to receive the discharged kitchen waste. And 22 is a scraping member provided between the outer circumferential surface of the dewatering basket 16 and the inner circumferential surface of the casing 7 so as to be able to come into contact with both surfaces or one side,
It is connected to the drive shaft 24 of the rotary disk 13 by a U-shaped support member 23, and is supported so as to rotate in synchronization with the rotary disk 13.

In the illustrated embodiment, the non-porous portion 16b of the dewatering basket 16
A water-shielding wall 25 is provided near the boundary between the non-porous portion 16b and the perforated portion 16a to prevent drainage water from entering between the inner periphery of the casing 7 and the inner periphery of the casing 7.
A scraping member 22 is provided between the outer circumferential surface of the perforated portion 16a and the inner circumferential surface of the casing 7 on the outside so as to also come into contact with the lower surface of the water-shielding wall 25. As the scraping member 22, an elastic material such as rubber or synthetic resin or a brush-like material is suitable. In addition, the support member 23 of the scraping member 22 is made of a slightly elastic material, so that the scraping member 22 comes into contact with the outer peripheral surface of the dewatering basket 16 when rotating at low speed or when the rotation is stopped, and due to centrifugal force when rotating at high speed. It can be provided so as to be displaced outward and come into contact with the inner circumferential surface of the casing 7. Of course, the scraping member 22 can also be brought into contact with both the outer circumferential surface of the dewatering cage 16 and the inner circumferential surface of the casing 7 at the same time. Note that if the support member 23 is elastic and the scraping member 22 is displaced outward due to centrifugal force during high-speed rotation, the scraping member 22 may be scraped at the opening 27 of the casing 7 that communicates with the drain pipe 26. Since there is a risk that the scraping member 22 may displace excessively outward and get caught on the periphery of the opening, it is recommended to provide a ring-shaped portion 28 or the like to restrict excessive outward displacement of the scraping member 22 at this portion. good.

29 is the outer peripheral surface of the chamber wall 10 of the crushing chamber 8 and the casing 7
A sliding contact member for scraping attached to an arbitrary blade support 19 to remove kitchen waste adhering to the ceiling surface of the room, and made of an elastic material such as rubber or a brush-like material.

The present invention is configured as described above, and when disposing kitchen waste, the drain plug 6 is removed and the waste disposal port 2 of the sink 1 is removed.
When kitchen waste is dumped from the crushing chamber 8, the kitchen waste enters the crushing chamber 8,
It accumulates on the rotary disk 13.

Then, after dumping the kitchen waste, the rear motor is driven to rotate the rotary disk 13 and the striking blades 15, 15 are rotated.
15 and a fixed blade 14 provided on the chamber wall 10 to crush the kitchen waste into a certain size. At this time, continue to pour an appropriate amount of water. Therefore, the crushed kitchen waste is sent out together with water by the centrifugal force of the rotating water flow accompanying the rotation of the striking blades 15, 15, and enters the truncated conical dewatering basket 16. Inside this dewatering basket 16, a blade 18 rotates along the inner circumference of the dehydrating basket 16, and the crushed kitchen waste sent out from the crushing chamber 8 is rotated inside the dehydrating basket 16 by the rotation of the blade 18. I am made to do so. The centrifugal force caused by this circumferential movement and the inverted truncated conical shape of the dewatering cage 16 combine to cause the crushed kitchen waste to gradually move upward while rotating along the conical surface, and during this time, the centrifugal force drains (dehydrates) the waste. It is done. The shredded kitchen waste that has moved upward from the dewatering basket 16 is discharged to the outside from the discharge port 21 of the casing portion, and is stored in a container, bag, or the like. Further, water is discharged into the sewer from the drain pipe 26. Therefore, in the present invention, a scraping member 22 is provided between the outer circumferential surface of the dewatering basket 16 and the inner circumferential surface of the casing 7 on the outside thereof, and is capable of coming into contact with both or one side of the scraping member 22. Since they are connected and supported, during the processing operation, the scraping member 22 rotates in contact with one or both of the outer circumferential surface of the dewatering basket 16 and the inner circumferential surface of the casing as the rotary disk 13 rotates. . Therefore, fine kitchen waste, slag, etc. contained in the water discharged from the drain hole 17 of the dehydration basket 16 are removed from the dehydration basket 1.
Even if it adheres to the outer circumferential surface of the dehydration basket 22 or the inner circumferential surface of the casing outside the dehydration basket 6, it is scraped off and removed by the scraping member 22, and this self-cleaning action causes the adhesion to the outer circumferential surface of the dewatering basket 22 and the inside of the casing. There is no possibility that kitchen waste or the like will remain on the peripheral surface. In particular, the support member 23 of the scraping member 22 is formed of a material having appropriate elasticity, and the scraping member 22
When the scraping member 22 is elastically pressed against and supported by the outer periphery of the dehydration basket 16, the scraping member 22 may touch the outer periphery of the dehydration basket 16 to some extent when the rotation is stopped, started, or rotated at low speed at the end of the rotation. When the scraping member 22 contacts strongly and rotates at high speed, a centrifugal force acts on the scraping member 22 and it is displaced outward against the elasticity of the support member 23, causing the scraping member 22 to touch the outer peripheral surface of the dewatering basket 16. On the one hand, it does not come into contact with the other, or on the other hand, it comes into contact very lightly, but on the other hand, it comes into some strong contact with the inner peripheral surface of the casing on the outside of the dewatering basket 16.

Therefore, one scraping member can reliably remove deposits on the outer periphery of the dewatering basket during low-speed rotation, and deposits on the inner periphery of the casing during high-speed rotation, and is only in strong contact with one of the surfaces. Frictional resistance is also not very large. Therefore, according to the device of the present invention, fine kitchen waste to be mixed into the waste water does not adhere to and remain on the outer circumferential surface of the dehydration basket and the inner circumferential surface of the casing on the outside thereof, and the attachment of these parts is prevented. It is possible to prevent the occurrence of putrid odor etc. due to kimono, and also to prevent clogging of the drain hole of the dehydrator, making it extremely suitable for this type of kitchen waste disposal machine.

Furthermore, since there is no need to increase the amount of water when processing kitchen waste, it can meet the demand for water conservation.
