Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage storage / conveying device that primarily stores garbage generated in a kitchen and then conveys the garbage together with a sink drain.

2. Description of the Related Art Conventionally, as a processing device for garbage generated in a kitchen, a device using a hammer mill type so-called disposer as a crushing device has been widely used.
In this garbage disposal device, the garbage thrown in from the drain outlet at the bottom of the sink is ground by a crusher with a hammer mill and finely crushed (crushed). Discharge.

On the other hand, it has also been proposed that food waste generated in the kitchen is cut (crushed) into a coarsely cut state without being finely pulverized and discharged to the outside through the drainage pipe along with the drainage.
Such a raw garbage processing apparatus by rough cutting is disclosed in the following Patent Document 1 and Patent Document 2.

In the case of the former garbage processing device using a disposer as a crushing device, the finely pulverized garbage becomes a slurry with the drainage, so it is discharged relatively smoothly through the drainage pipe as the drainage is discharged. However, there is a problem that the garbage after pulverization adheres to and accumulates on the drainage pipe, particularly on a trap part (drainage trap part) provided on the drainage pipe.
In particular, in the case of the latter garbage processing equipment that crushes garbage into a rough cut state, it is difficult to drain the crushed garbage as it is with normal sink drainage, and after crushing compared to the former garbage processing equipment Of waste remains in the drain side trap, and it is easy to accumulate.

Therefore, in the previous patent application (Japanese Patent Application No. 2004-286702, unpublished), the present applicant provides a water storage tank for storing transport water, supplies tap water (water) to the water storage tank, and supplies a predetermined amount of transport water there. Proposal is made by opening the discharge valve to discharge the internal transport water all at once, and to clean up the crushed garbage remaining in the drain side trap with the transport water. is doing.
If it does in this way, even if it is rough cut garbage, it will become possible to discharge outside through a drainage pipe without trouble.
In this case, however, the water supply pipe for tap water (water supply) must be raised above the overflowing counter, and the sink must be cut off from the sink. The appearance of will also look bad.
In addition, a large amount of water is consumed, which is not desirable from the viewpoint of saving water.

  Therefore, the applicant next does not store the fresh water in the water storage tank, but causes the sink water flowing out from the sink (herein, the water flowing out through the sink) to flow into the water storage tank through the inflow pipe. Have been proposed to be discharged from the water storage tank as transport water (Japanese Patent Application No. 2005-133097: unpublished).

FIG. 6 shows a specific example.

223 is a drain pipe, and the upper part is branched into a main pipe 223-1 and a branch pipe 223-2, the main pipe 223-1 is connected to the crushing device 210, and the branch pipe 223-2 is a siphon pipe 222. Are connected to the falling pipe 220.
A drain side trap 224 is provided in the drain pipe 223 on the downstream side of the junction.
In the apparatus shown in FIG. 6, the garbage crushed by the crushing apparatus 210 is temporarily stored in the drain side trap section 224.

The sink drainage stored in the water storage tank 216 is used as the transporting water for garbage, and this transporting water is discharged to the drainage pipe 223 side by the siphon action by the siphon pipe 222 and temporarily sent to the drainage side trap section 224. The crushed garbage that is stored in the waste water is discharged from the drain side trap section 224 to the downstream side at once by the transport water.
That is, the garbage after crushing in the drain side trap section 224 is swept away from the storage tank 216 by the transport water.

In the case of the apparatus shown in FIG. 6, it is not necessary to provide a means for cutting edges on the water supply path to the water storage tank 216, so that the water supply path to the water storage tank 216 is simplified and the appearance on the counter 204 is , It can also be made to look good.
In addition, it becomes possible to use the sink drainage that should be discarded as it is as the transport water for garbage, thus saving water.

By the way, in the case of the apparatus shown in FIG. 6, the sink drainage is divided into two paths and the piping path for discharging the sink drainage is complicated.
Even in the garbage processing apparatus using a disposer as the crushing device, there is a problem that the garbage after pulverization remains in the drain side trap section 224. Therefore, even in this case, the garbage is stored in the water storage tank 216. It is possible to store the transport water and discharge it all at once, and it is possible to smoothly discharge heavy things such as egg shells and fish bones remaining in the drain side trap section 224.
Even in this case, if the sink drainage is stored in the water storage tank 216, a new problem similar to the above is caused.

In addition, there exists what was disclosed by the following patent document 3 as a prior art with respect to this invention.
The thing disclosed in this Patent Document 3 is to collect sink drainage in a tank and discharge it by the action of a siphon tube. However, the thing disclosed in this Patent Document 3 cannot force the siphon action to occur. This is different from the present invention.

The sink drainage is left in the second chamber during the siphon action, and the first chamber and the second chamber are respectively disposed in the lower portion inside the storage tank and the upper space above the reference water level. It is characterized in that a communication small hole for communicating is provided.

Effects and effects of the invention

  As described above, the present invention provides a storage tank having a function of storing garbage and sink wastewater, an inflow pipe in which the lower end is immersed in the sink wastewater in the storage tank, and the siphon wastewater in the storage tank together with garbage. Drainage trap part composed of a siphon pipe discharged by the action, a storage tank and a riser pipe of the siphon pipe, a vent opening for venting the upper space of the storage tank, and a forced discharge forcing the siphon action And a garbage storage and transfer device.

  According to the present invention, it is not necessary to provide a means for cutting the edge on the water supply path to the storage tank. Therefore, the water supply path to the storage tank is simplified, and the appearance and appearance on the counter are good. In addition, the sink drainage that should be discarded as it is can be used as the garbage transport water, and water can be saved.

  In addition, according to the present invention, since the sink waste water in the storage tank, that is, the transport water is discharged together with the garbage by a siphon action, the garbage in the storage tank is stored with a strong transport force without leaving any waste. In addition to being able to discharge from the tank, it is also possible to effectively prevent garbage from remaining and depositing on the drain pipe and causing the risk of clogging.

  Furthermore, in order to discharge the sink waste water in the storage tank by siphon action, it can be unnecessary to provide a discharge valve for discharging the sink waste water in the storage tank, or to provide an opening / closing mechanism for opening and closing the discharge valve, The apparatus configuration can be simplified.

  In the apparatus of the present invention, the storage tank has a function of storing sink drainage, that is, transport water, and a function of storing garbage. Further, the storage tank and the riser pipe of the siphon pipe serve as a drain side trap section. Therefore, it is not necessary to divide the sink drainage into two systems of the water storage tank side, the crushing device and the drainage side trap part side as in the apparatus shown in FIG. It is not necessary to provide a separate drain side trap, simplifying the path for sink drainage and garbage discharge, simplifying the piping structure, and the inflow pipe into the sink drainage of the storage tank. In order to prevent the odor from flowing backward from the storage tank, the inflow side trap portion 217 of the apparatus shown in FIG. 6 can be omitted.

  The device of the present invention also includes a forced discharge means for forcibly causing a siphon action by the action of the siphon tube and discharging the sink waste water in the storage tank together with the garbage. Siphon action can be triggered at an appropriate timing.

For example, if the drainage of sink wastewater in the storage tank is left to the spontaneous siphon action that occurs when a large amount of sink wastewater flows into the storage tank, the garbage is not collected in the storage tank. However, the sink drainage in the storage tank is discharged and lost, and the sink drainage is not efficiently used as transport water. However, the siphon action is forced to occur according to the present invention. In this case, when a large amount of garbage is collected in the storage tank, it becomes possible to perform siphon action, that is, discharge of garbage accompanied by conveyance by sink drainage, and efficient use of sink drainage as conveyance water. it can.
Here, in order to force the siphon action to occur, the shape, thickness, height, or the like of the siphon tube can be selected so that the spontaneous siphon action does not occur as much as possible.

In the present invention, the storage tank can be directly connected to the drain outlet at the bottom of the sink via the inflow pipe.
Even in this case, small-sized garbage such as rice grains flows into the storage tank together with the sink drainage, so that the storage tank also functions as a storage tank for food waste.
However, according to the present invention, the storage tank can be connected to the garbage crushing device via the inflow pipe according to claim 2 to store the food waste crushed by the crushing device.

In the present invention, the forcible discharge means may be configured to apply a pneumatic pressure to the storage tank to push down the sink drainage in the storage tank and forcibly cause the siphon action by the siphon pipe. ).
In this case, the vent can be used as a pneumatic inlet.

According to a fourth aspect of the present invention, an air supply device is provided for forcibly injecting air into the sink drainage in the storage tank from the bottom or side inlet of the storage tank.
Most of the garbage stored in the storage tank is accumulated at the bottom, and when the siphon action is caused by the siphon tube, the garbage collected at the bottom becomes a large resistance during the siphon action. As a result, there is a risk that the siphon action is not smoothly induced.

However, if the sink waste water in the storage tank is stirred together with the garbage according to claim 4 and the siphon action is caused to occur in that state, the siphon action can be caused smoothly by reducing the resistance caused by the garbage, In addition, the flow of garbage can be made smooth, and the garbage in the storage tank can be discharged efficiently.
In this case, the air supply device can also serve as a forced discharge means for forcibly causing siphon action by applying air pressure to the storage tank.
In this case, air can be escaped from the vent by providing an open / close valve on the vent passage communicating with the vent and closing the valve or reducing the flow path of the vent. It is desirable to prevent or suppress.

  Next, according to the fifth aspect of the present invention, a partition wall is provided for partitioning the interior of the storage tank into an inflow pipe, a vent and a first chamber on the siphon tube side and a second chamber on the opposite side. While draining the sink drain in the room, the sink drain remains in the second chamber, and the first chamber and the second chamber communicate with each other in the lower part inside the storage tank and the upper space above the reference water level. It is designed to communicate with a small hole.

  In the apparatus of the present invention, the storage tank holds the sink drainage as sealed water and constitutes a drain side trap part together with the riser pipe of the siphon pipe, and therefore the total amount of sink drainage in the storage tank is the siphon action. If it is discharged, the odor backflow prevention function is lost at this time.

  Therefore, in claim 5, the sink drainage is left in the second chamber during the siphon operation, and after the siphon operation, the sink drainage in the second chamber is gradually allowed to flow into the first chamber through the lower communication small hole to restore the trap function. In this way, it is possible to keep the trap function in the storage tank without waiting for the sink drainage to newly flow into the storage tank.

Next, embodiments of the present invention will be described in detail with reference to the drawings.
In FIG. 1, 10 is a kitchen sink, 12 is a sink, 14 is a counter, and 16 is a sink faucet provided upright on the counter 14.
A garbage crushing device 18 is provided in a state of being connected to the sink bottom portion 12A in a state in which the top inlet 20 matches the drain outlet of the sink bottom 12A.

  In the present embodiment, the crushing device 18 cuts (crushes) the raw garbage into a rough cut state without finely pulverizing it. The container 22 is provided inside thereof, and the input raw garbage is cut with a cutting blade. A crushing mechanism 24 for crushing and crushing, and a motor 26 for rotating the crushing mechanism 24 are provided.

The apparatus of this embodiment has a storage tank 30 and an inflow pipe 32.
The inflow pipe 32 allows the garbage crushed by the crushing device 18 and the sink waste water flowing out of the sink 12 to flow into the storage tank 30, and its upper end is connected to the discharge port of the crushing device 18 and its lower end. Protrudes below the reference water level (set water level) 34 in the storage tank 30.
That is, the lower end of the inflow pipe 32 protrudes below the reference water level 34 of the sink drainage stored in the storage tank 30, and the lower end of the inlet pipe 32 enters the stored sink drainage.

The storage tank 30 serves to store the garbage and the sink waste water crushed by the crushing device 18 inside.
The storage tank 30 is provided with a vent 38 at its upper end for supplying air to the upper space 36 above the reference water level 34 or for extracting the air in the upper space 36 to the outside. A vent pipe 40 rises upward from the vent 38.
An air supply device 44 as a forced discharge means is connected to the air passage 42 passing through the inside of the air pipe 40.

The air supply device 44 includes a pump 46 that pressurizes and sends air, an air supply path 48, and a check valve 50 provided on the air supply path 48.
Here, the check valve 50 is a unidirectional valve that opens in the direction in which the pressurized air from the pump 46 is supplied and closes in the reverse direction.
An on-off valve 52 is provided on the air passage 42. Here, the on-off valve 52 is kept open in a normal state, and is closed when the air supply device 44 supplies air pressure into the storage tank 30.

A siphon tube 53 is connected to the bottom of the storage tank 30.
The siphon tube 53 has a rising tube 54 rising from the bottom of the storage tank 30 and a falling tube 56 falling downward from the upper end of the storage tank 30, and has a reverse U-shape as a whole. A drain pipe 58 is connected to 56.

In the present embodiment, the reference water level 34 of the sink drainage in the storage tank 30 is determined by the height of the wear part 60 of the siphon tube 53, and here the reference water level 34 determined by the wear part 60 is from the upper end of the storage tank 30. It is set at a slightly lower position.
The siphon tube 53 has an upper end higher than the upper end of the storage tank 30 and protrudes upward to some extent.
As a result, even if the sink drainage flows into the storage tank 30 in a large amount at once, it is difficult for the spontaneous siphon action to occur.
This storage tank 30 constitutes a drain side trap section 28 together with a riser pipe 54 in the siphon pipe 53, and holds the sink drainage as sealed water to prevent the reverse flow of odor from the drain pipe 58. .

The other end of the air passage 42 leading to the air vent 38 is connected to the downstream portion of the rising pipe 54 in the siphon pipe 53. Specifically, it is connected to the downcomer 56 here.
However, the connection position may be the upper end portion of the siphon pipe 53 or may be the drain pipe 58 side.

  If the air passage 42 is opened to the sink 12 side, there is a problem that odor generated in the storage tank 30 flows back to the sink 12 side through the air passage 42. Here, the end of the air passage 42 is drained. Since it is connected to the secondary side of the side trap portion 28, such inconvenience does not occur.

Next, the operation of this apparatus will be described below.
In the apparatus of the present embodiment, the garbage generated in the kitchen is thrown into the crushing apparatus 18 through the inlet 20.
Then, the water supplied from the sink faucet 16, that is, the garbage put under the sink drain water is cut (crushed) by the crushing device 18 and flows into the storage tank 30 through the inflow pipe 32 together with the sink drain. Garbage after crushing is stored together with sink drainage.

When the sink drainage flows into the storage tank 30 through the inflow pipe 32, the air inside the storage tank 30 is expelled from the storage tank 30 through the vent 38.
Accordingly, the air trapped inside the storage tank 30 prevents the smooth drainage of the sink wastewater into the storage tank 30 or prevents the sink drainage water level inside the storage tank 30 from rising to the reference water level 34. It does not happen.

  When the crushed garbage is accumulated in the storage tank 30 to some extent, when air pressure is applied to the storage tank 30 from the air supply device 44 as a forced discharge means in the direction of the arrow in FIG. As a result, the water surface of the sink drain in the storage tank 30 is pushed downward, and as a result, the inside of the siphon pipe 53 is filled with water, and a siphon action is generated by the siphon pipe 53 here, and after the crushing stored in the storage tank 30 A large amount of garbage is discharged to the drain pipe 58 side through the siphon pipe 53 in a large amount using the sink waste water stored in the storage tank 30 as the transport water.

  Thereafter, sink water flows into the storage tank 30 to raise its water surface. When the water level finally reaches the reference water level 34, the water surface stops rising and returns to the state shown in FIG.

  As described above, in the present embodiment, the storage tank 30 that serves to store garbage and sink wastewater, the inflow pipe 32 that immerses the lower end in the sink wastewater in the storage tank 30, and the sink wastewater in the storage tank 30. A siphon pipe 53 that discharges the garbage together with garbage, a drain side trap section 28 constituted by the storage tank 30 and the rising pipe 54, a vent hole 38 that ventilates the upper space 36 of the storage tank 30, and a forced Since the garbage storing and conveying device is configured to include the air supply device 44 that causes the siphon action, there is no need to provide a means for cutting the edge on the water supply path to the storing tank 30. Therefore, the water supply path to the storage tank 30 can be simplified, and the appearance and appearance on the counter 14 can be improved, and at the same time, it should be discarded as it is. The click drainage it is possible to utilize as carrier water in the garbage, can play a water saving.

  In addition, in the present embodiment, since the sink waste water, that is, the transport water in the storage tank 30 is discharged together with the garbage by a siphon action, the garbage in the storage tank 30 is strong enough. In addition to being able to discharge from the storage tank 30 by the conveying force, it is possible to effectively prevent garbage from remaining and accumulating on the drainage pipe and causing the risk of clogging. It is unnecessary to provide a discharge valve for discharging the waste water or to provide an opening / closing mechanism for opening / closing the discharge valve, and the apparatus configuration can be simplified.

  In the apparatus of this embodiment, the storage tank 30 functions to store sink drainage, that is, transport water, to store garbage, and to hold the internal sink drainage as sealed water and together with the riser 54, the drain side trap section. 28, it is possible to simplify the path for sink drainage and garbage discharge, simplify the piping structure, and additionally provide a drain side trap portion on the drainage path. The configuration of the apparatus can be further simplified because it is not necessary.

  Furthermore, since the lower end portion of the inflow pipe 32 is inserted into the sink drainage in the storage tank 30, it is possible to eliminate the need to provide an inflow side trap portion for preventing the backflow of odor from the storage tank 30, Furthermore, siphon action can be effectively caused by supplying air pressure into the storage tank 30.

  The apparatus of the present embodiment is also provided with an air supply device 44 that forcibly causes siphon action through the siphon tube 53 and discharges the sink waste water in the storage tank 30 together with garbage as a forced discharge means. When a large amount of garbage is stored in the tank 30, siphon action, that is, discharge of garbage accompanied by conveyance by sink drainage can be performed, and sink drainage can be efficiently used as conveyance water. .

FIG. 3 shows another embodiment of the present invention.
In this embodiment, a plurality (or one) of inlets 62 may be provided at the bottom of the storage tank 30, and the air supply path 48 of the air supply device 44 is connected to the inlets 62. The pressurized air is injected into the storage tank 30 through each inlet 62, and the garbage and sink waste water in the storage tank 30 are agitated by the injected air.

  Also in this embodiment, the air supply device 44 serves as a forced discharge means for forcibly causing a siphon action to discharge the garbage in the storage tank 30 together with the sink drainage. Only the valve 52 is provided, and the air supply device 44 as shown in FIG. 1 is not connected to the air passage 42.

  In this embodiment, the air supply device 44 injects air from the respective inlets 62 into the storage tank 30 to perform stirring, and at the same time, air pressure is applied to the interior of the storage tank 30 so that the water surface of the internal sink drainage is removed. When pushing down, the on-off valve 52 on the air passage 42 is closed.

  In the present embodiment, air is forcibly injected into the sink drain in the storage tank 30 and agitation is performed to cause the siphon action. In this state, the siphon action is smoothed by reducing resistance caused by garbage. In addition, the flow of garbage can be made smooth, and the garbage in the storage tank 30 can be discharged efficiently.

  In the embodiment shown in FIG. 3, the air supply device 44 is used only for agitation by supplying air through each inlet 62, that is, it is used only as an agitation device without acting as a forced discharge means. As shown in FIG. 4, a forced discharge means can be provided separately.

  In the embodiment of FIG. 4, the siphon tube 53 is made of a flexible tube, and its upper end can be raised and lowered, and its upper end is driven up and down by a raising and lowering drive device 64 as a forced discharge means. It has become.

  The raising / lowering driving device 64 includes a driving pulley 66, a driven pulley 68, an endless annular belt 70 wound around them, a motor 72 for rotating the driving pulley 66, and a rotation of the belt 70 fixed to the belt 70. And an arm 74 that moves up and down.

  A holding portion 76 is provided at the distal end portion of the arm 74, and the upper end portion of the siphon tube 53 is held by the holding portion 76, and the upper end portion of the siphon tube 53 is driven up and down as the arm 74 is raised and lowered. It is like that.

In the embodiment of FIG. 4, the siphon action is suppressed by naturally raising the upper end of the siphon tube 53 to a certain height by the lifting drive device 64, and the reference water level 34 of FIG. Sink drainage can be kept in the storage state.
On the other hand, by lowering the upper end portion of the siphon tube 53 by the lift drive device 64 in this state, the upper end portion of the siphon tube 53 is filled with water, and the siphon action can be forced.

  As described above, the air supply device 44 of FIG. 3 is operated only as an agitator by supplying air, and the discharge of the garbage and the sink wastewater in the storage tank 30 by the forced siphon action is raised and lowered as another forced discharge means. If it is performed by the driving device 64, it becomes possible to use a small pump 46 with a small output and a small capacity in the air supply device 44, and the cost required for the device can be reduced.

  In the embodiment shown in FIG. 1, the air supply device 44 connected to the air passage 42 is omitted, and it is of course possible to provide a lifting drive device 64 as a forced discharge means shown in FIG. It is.

FIG. 5 shows still another embodiment of the present invention.
In this embodiment, a partition wall 78 is provided inside the storage tank 30, and the partition wall 78 allows the interior of the storage tank 30 to be in the first chamber 80 on the side of the inflow pipe 32, the vent 38 and the siphon pipe 53, and on the opposite side. This is an example in which two small chambers 84 and 86 are provided for partitioning into two chambers 82 and communicating between the first chamber 80 and the second chamber 82 at the lower and upper portions of the partition wall 78.

In this embodiment, when the siphon action by the siphon tube 53 occurs, the sink wastewater in the first chamber 80 in the storage tank 30 is mainly discharged, and the sink wastewater in the second chamber 82 remains almost as it is. As such, the size of the lower communication small hole 84 is determined.
Thereafter, the sink drain remaining in the second chamber 82 gradually flows into the first chamber 80 through the small communication hole 84, and the water level of the sink drain in the first chamber 80 is raised to recover the sealed water.
