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 the drain trap 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 trap part, 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Therefore, in the previous patent application (Japanese Patent Application No. 2004-286702, unpublished), the present applicant provides a water storage tank for storing transport water, supplies tap water (water) to the water storage tank, and supplies a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. The waste water that has been stored in the drain trap part is discharged at once by opening the discharge valve, and the garbage after crushing that remains in the drain trap is proposed to be swept away with the transport water. ing.
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. 5 shows a specific example thereof.
In the figure, 200 is a kitchen sink, 202 is a sink, 204 is a counter, and 206 is a sink faucet provided on the counter 204.
A garbage crushing device 210 is connected to the sink bottom 202A at a drain outlet 208, and the garbage can be introduced into the inside through the inlet 212.
A part of the sink drainage also flows into the crushing device 210.
The thrown-in garbage is crushed by the crushing device 210 under sink water, specifically, water supplied from the sink faucet 206.

An annular water channel 214 is provided around the charging port 212 of the crushing device 210 so as to communicate with the drain port 208, and the remaining part of the sink drainage is allowed to flow into the annular water channel 214.
Sink drainage flowing into the annular water channel 214 is introduced into a water storage tank 216 provided inside the cabinet of the sink 200 and below the sink 202 through an inflow pipe 218 extending horizontally, and a certain amount of water is stored therein. .
An inverted U-shaped siphon tube 222 having a rising pipe 219 and a falling pipe 220 is connected to the bottom of the water storage tank 216.

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 trap 224 is provided in the drain pipe 223 on the downstream side of the junction.
In the apparatus shown in FIG. 5, the garbage crushed by the crushing apparatus 210 is temporarily stored in the drain 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 drain trap section 224. The garbage after crushing stored in the tank is discharged from the drain trap part 224 to the downstream side at once by the transport water.
That is, the crushed garbage in the drain trap 224 is swept away from the storage tank 216 by the transport water.

In the case of the apparatus shown in FIG. 5, 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. 5, 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 trap part 224. Therefore, even in this case, the garbage is conveyed into the water storage tank 216. Water can be stored and discharged at a time, and heavy items such as egg shells and fish bones remaining in the drain trap part 224 can be discharged smoothly.
Even in this case, if the sink drainage is stored in the water storage tank 216, the same problem as described 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.

Another prior art is disclosed in Patent Document 4 below.
However, what is disclosed in Patent Document 4 relates to toilet drainage, the subject of which is different from the present invention, and the technical field is also different.

And

Effects and effects of the invention

  As described above, the present invention is a siphon pipe that discharges sink wastewater in a storage tank having a function of storing garbage and sink wastewater together with garbage by siphon action, a drain trap section provided on the downstream side of the siphon pipe, A garbage storage and transfer device is configured including suction means for raising the siphon by sucking air in the space in the siphon tube.

  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 accumulating in the drainage 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.

  Further, in the apparatus of the present invention, since the water storage tank has a function of storing sink wastewater, that is, conveying water, and a function of storing garbage, as shown in FIG. There is no need to divide the system into two systems and then rejoin them, and the path for sink drainage and garbage discharge can be simplified, simplifying the piping structure and the overall system configuration And the device cost can be reduced.

  The apparatus of the present invention also includes suction means as a forced discharge means for forcibly causing the siphon action by the action of the siphon tube and discharging the sink waste water in the storage tank together with the garbage, thereby causing the siphon action. The siphon action can be started when desired, that is, at an appropriate timing.

For example, if the discharge 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. Sink drainage in the storage tank is discharged and lost, and there are cases where the sink drainage is not efficiently used as transport water, but when the siphon action is forced to occur according to the present invention, When a large amount of garbage is collected in the storage tank, 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.
Here, in order to cause the forced siphon to occur, the shape, thickness, height, or the like of the siphon tube can be selected so that a spontaneous siphon is not generated as much as possible.

  In the present invention, a sealed trap space is formed in the siphon tube by holding a sealed water downstream of the siphon tube to prevent odor backflow, and the air in the sealed space is sucked in. By doing so, the inside of the siphon tube is filled and the siphon action is caused, so that the siphon action can be easily caused by a simple method and apparatus.

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.

Next, a third aspect of the present invention is provided with a stirring device that performs stirring by forcibly injecting air or water or air and water 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 wastewater in the storage tank is agitated with the garbage according to claim 3 and the siphon action is caused 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 claim 3, it is also possible to stir by injecting only water from the inlet, but the stirring effect when water and air are injected is greater than that of water alone. When injecting, it is effective and desirable to blow air.
However, it is also possible to inject both air and water into the storage tank from the inlet.

In this case, as a suction means for sucking the air in the space in the siphon tube, water is injected into the storage tank from the inlet through the water channel, and negative pressure is generated by the negative pressure generator formed at the throttle part in the middle of the water channel. Then, the air in the siphon tube is sucked with the negative pressure, and the sucked air can be injected into the storage tank through the water channel from the inlet with water.
If it does in this way, the function as a suction means and the function as a stirring device can be performed in a single device, that is, an aspirator, and the configuration of the device can be simplified.
