Description

  The present invention relates to a garbage processing apparatus, and more particularly to a food waste transporting means after being crushed by a crushing apparatus.

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Therefore, in the previous patent application (Japanese Patent Application No. 2004-286702, unpublished), the present applicant provides a water storage tank for storing the transport water, and supplies tap water (water) to the water storage tank to supply a predetermined amount of transport water. Stored there and opened the discharge valve to discharge the internal transport water all at once, and cleaned the crushed garbage remaining in the drain side trap section with the transport water. is suggesting.
In this way, even roughly cut garbage can be discharged to the outside through the drainage pipe without any 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, instead of storing fresh water in the water storage tank, sink wastewater flowing out from the sink (herein, water flowing out through the sink) flows into the water storage tank through the inflow pipe, and is stored and transported. It can be considered that water is discharged from the water storage tank at once.
In this way, it is not necessary to provide a means for cutting the edge of the water supply path to the water storage tank. Therefore, the water supply path to the water storage tank is simplified and the appearance and appearance on the counter are improved. be able to.
In addition, it becomes possible to use the sink wastewater that should be discarded as it is as the transport water for garbage.

  However, unlike when water is stored in the water storage tank, when the sink drainage is stored in the water storage tank, dirty water will flow into the water storage tank. There is a new problem that the inside becomes dirty and the odor generated inside flows back to the sink side through the inflow conduit.

In addition, even in the garbage processing apparatus using a disposer as the crushing device, there is a problem that the garbage after crushing remains in the drain side trap part. Therefore, even in this case, the transport water is put into the water storage tank. It can be stored and discharged all at once, and heavy items such as egg shells and fish bones remaining inside the drain side trap can be discharged smoothly.
Even in this case, if the sink drainage is stored in the water storage tank, a new problem similar to the above is caused.

JP 2002-219375 A Japanese Patent Publication No.5-156035

  In the background of the above situation, the present invention stores sink wastewater in a water storage tank to serve as transport water, and discharges it from the water storage tank at once to clean up garbage after crushing the drain side trap portion. In this case, the object is to provide a garbage disposal device capable of preventing the odor from the water storage tank from flowing back to the sink side.

  Thus, according to the first aspect of the present invention, there is provided (a) a garbage crushing device disposed below the sink in a state where the interior communicates with the drain outlet at the bottom of the sink, and (b) an outflow from the sink. A sink tank that allows the sink waste water to flow through the inflow pipe and stores it as transport water for garbage, and (c) a rise pipe and a fall pipe that falls from the upper end of the rise pipe, and is connected to the water storage tank And a siphon pipe that discharges the transport water in the water storage tank to the drain pipe by siphon action, and (d) is provided in the inflow pipe to hold the sealed water and prevent back flow of odor from the water tank And an inflow side trap portion.

  According to a second aspect of the present invention, in the first aspect, a vent pipe for supplying air to the water storage tank from the secondary side of the drain side trap portion provided in the drain pipe is provided.

  According to a third aspect of the present invention, in any one of the first and second aspects, an elevating drive means for elevating and lowering the upper end portion of the siphon tube is provided.

  According to a fourth aspect of the present invention, in the second aspect, the upper end portion of the siphon tube can be moved up and down, and elevating drive means for moving the upper end portion up and down is provided, and the vent pipe is connected to the upper end portion of the water storage tank. The vent pipe is also used as an overflow pipe.

  According to a fifth aspect of the present invention, in any one of the third and fourth aspects, there is provided detection means for detecting garbage accumulation in the drain side trap portion, and the upper end of the siphon tube when the accumulation amount reaches a set amount. It is characterized in that the part is driven downward to cause a siphon.

  According to a sixth aspect of the present invention, in any one of the third and fourth aspects, the upper end of the siphon tube is driven downward in conjunction with the crushing operation of the crushing device, thereby causing a siphon. To do.

Effects and effects of the invention

  As described above, the present invention is provided with the inflow side trap portion that holds the sealed water and prevents the reverse flow of the odor from the water storage tank in the middle of the inflow conduit from the sink to the water storage tank. According to the above, when the sink wastewater is stored in the storage tank as transported food for garbage after crushing, the storage tank becomes dirty and emits odor due to the dirty water flowing into the storage tank. Even in this case, it is possible to effectively prevent the odor from flowing back to the sink side.

In the present invention, the siphon pipe is connected to the water storage tank so that the water in the water storage tank is discharged to the drain pipe by the siphon action. According to the present invention, the transport water in the water storage tank is discharged. Therefore, it is not necessary to provide a discharge valve for opening or an opening / closing mechanism for opening / closing the discharge valve, and the apparatus configuration can be simplified.
The siphon action by the siphon pipe can be caused to occur spontaneously by causing the siphon pipe to fill up when a large amount of sink drainage flows into the water storage tank at once. As described later, the siphon action can be intentionally caused.

  According to the present invention, the sink drainage stored in the water storage tank, that is, the discharge of the transport water from the water storage tank at once can be wiped out the inside of the drain side trap portion provided in the drain pipe, It is possible to effectively prevent a large amount of garbage after crushing from being accumulated in the drain side trap portion and clogging of the drain pipe due to the accumulation.

According to a second aspect of the present invention, a vent pipe for supplying air to the water storage tank from the secondary side of the drain side trap portion provided in the drain pipe is provided.
This vent pipe has the following meaning.
That is, when the inflow side trap portion is provided between the water storage tank and the sink according to claim 1, a negative pressure is generated in the water storage tank when the transport water in the water storage tank is discharged by the siphon action of the siphon tube, Due to the negative pressure, the water in the storage tank is not discharged smoothly, or the sealed water in the inflow side trap section is drawn into the water storage tank, causing the inflow side trap section to run out of seal water and break the seal. There is a risk that
However, if a vent pipe for supplying air is provided in the water storage tank according to claim 2, the occurrence of such problems can be effectively prevented, and the water transported in the water storage tank can be discharged smoothly, It is possible to satisfactorily prevent breakage at the inflow side trap portion.

According to a third aspect of the present invention, there is provided an elevating drive means for elevating and lowering the upper end portion of the siphon tube.
According to the third aspect, the siphon action can be forcibly caused by lowering the upper end portion of the siphon tube by the lifting drive means.
As described above, in claim 1, it is possible to cause a siphon action by the siphon tube spontaneously when a large amount of sink drainage flows into the water storage tank at once.
However, in this case, the garbage after crushing hardly accumulates in the drain side trap part, or even if it is a small amount, a large amount of transport water is consumed.

  However, if the siphon action is forcibly caused according to claim 3, it becomes possible to discharge the transport water at an appropriate timing such as when a large amount of garbage after crushing is accumulated in the drain side trap part, In addition, the transport water in the water storage tank can be used for transporting garbage.

According to a fourth aspect of the present invention, the vent pipe is connected to the upper end portion of the water storage tank so that the vent pipe is also used as the overflow pipe of the water storage tank.
According to this fourth aspect, when a large amount of sink wastewater flows into the water storage tank at a time, the excess water is discharged from the overflow pipe, so that the water transported in the water storage tank can be naturally generated by siphon action. Release can be effectively prevented.
In addition, when a large amount of garbage after crushing is collected in the drain side trap part, when trying to release the transport water in the water storage tank, a spontaneous siphon action has already occurred before that, and the water storage tank It is also possible to avoid the problem that the necessary amount of transport water is not stored in the interior and the transport force for the garbage in the drain side trap section is insufficient.

  Next, according to the fifth aspect of the present invention, there is provided a detecting means for detecting garbage accumulation in the drain side trap portion, and when the accumulation amount reaches a set amount, the upper end portion of the siphon tube is driven downward to cause siphon. Therefore, if it does in this way, it can prevent favorably that the garbage after crushing accumulates excessively in a drain side trap part.

On the other hand, according to the sixth aspect of the present invention, the upper end portion of the siphon tube is driven downward in conjunction with the crushing operation of the crushing device, thereby causing the siphon.
The fact that the crushing device performed crushing operation means that the garbage after crushing flows into the drain side trap part, so that siphon action is caused in conjunction with the crushing operation of the crushing device. Thus, it is possible to effectively prevent garbage from being crushed in the drain trap section.

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 in an upright state on the counter 14.

That is, in this embodiment, a part of the sink waste water is supplied to the crushing device 20 side through the inlet 24 and the other part is supplied to the water channel 30 side through the through hole 34 of the eye plate 32.

The size of the through hole 34 is desirably 10 mm or less, and more desirably 1 to 5 mm.
If the size of the through hole 34 is smaller than this, it is difficult to divide the sink drainage into a later-described inflow pipe 35A side in a sufficient amount, and if the size of the through hole 34 is larger than this, The inside garbage flows into the inflow conduit 35 </ b> A through the through hole 34.

An inflow pipe 35 extends laterally from the annular water channel 30 and its tip is connected to a water storage tank 37 shown in FIG.
Therefore, the sink waste water supplied to the annular water channel 30 side is supplied to the water storage tank 37 through the inflow pipe 35A in the sideways inflow pipe 35, and is stored in a predetermined amount as garbage transport water.

As shown in detail in FIG. 3, the inflow pipe 35 is provided with an inflow side trap portion 36, in which sealed water is held.
The inflow side trap portion 36 functions to prevent the odor in the water storage tank 37 from flowing back to the sink 12 side through the inflow conduit 35A and the drain port 18 of the sink bottom portion 12A.

As shown in FIG. 3, the bottom portion 37A of the water storage tank 37 is inclined obliquely downward to the right in the figure, and a connection port 38 communicating with the inside of the tank is provided at the right end portion. A siphon tube 44 having a rising tube 40 and a falling tube 42 falling from the upper end of the rising tube 40 and having an inverted U-shape as a whole is connected to the lower end of the rising tube 40.
As shown in FIG. 1, the drain pipe 26 is provided with a branch pipe 46, and the lower end portion of the down pipe 42 in the siphon pipe 44 is inserted into the branch pipe 46.
Here, the siphon tube 44 is made of a flexible tube and has a smaller diameter than the branch tube 46.

As shown in FIG. 5, the drain trap side 28 is provided with a window 48, and the accumulated amount of garbage after crushing in the drain trap 28 is detected facing the window 48. A sensor (detection means) 50 is provided.
Here, a reflective infrared sensor is used as the sensor 50, and it is detected whether or not the amount of garbage after crushing in the drain side trap portion 28 has reached a set amount according to the amount of reflected light. .

The siphon tube 44 can move up and down at its upper end, and the upper end of the siphon tube 44 is driven up and down by a lift driving device 52 shown in FIG.
The elevating drive device 52 includes a drive pulley 54, a driven pulley 56, an endless annular belt 58 wound around them, a motor 60 that rotationally drives the drive pulley 54, and a belt 58 fixed to the belt 58. And an arm 62 that moves up and down with rotation.
A holding portion 64 is provided at the distal end portion of the arm 62, and the upper end portion of the siphon tube 44 is held by the holding portion 64, and the upper end portion of the siphon tube 44 is driven up and down as the arm 62 moves up and down. It is like that.

In FIG. 1, reference numeral 66 denotes a vent pipe whose upper end is connected to the upper end of the water storage tank 37 and whose lower end is connected to the secondary side, that is, the downstream side of the drain side trap portion 28.
The ventilation pipe 66 serves to supply the air in the drain pipe 26 to the water storage tank 37.
The vent pipe 66 also serves as an overflow pipe 66 that simultaneously overflows the water in the water storage tank 37 to the drain pipe 26 side.

  In FIG. 1, reference numeral 68 denotes a control unit for controlling the operation of the apparatus. The control unit 68 detects the amount of garbage deposited after crushing in the drain side trap unit 28, and moves up and down to drive the siphon tube 44 up and down. The motor 60 of the drive device 52 and the motor 22 of the crushing device 20 are electrically connected so that the lifting drive device 52 is controlled based on a detection signal from the sensor 50 or in conjunction with the crushing operation of the crushing device 20. It has become.

Next, the operation of the garbage processing apparatus of this embodiment will be described.
In the present embodiment, a part of the sink drainage is supplied to the water storage tank 37 through the annular water passage 30 and the inflow conduit 35A, and is stored there as transport water.
The amount of stored water is determined by the overflow pipe 66, and as shown in FIG. 3, the sink drainage is normally stored as transport water in the water storage tank 37 up to the overflow position of the overflow pipe 66.

During the garbage treatment, the garbage is put into the crushing device 20 through the inlet 24 of the crushing device 20.
Garbage thrown into the crushing device 20 is crushed (roughly cut) into a predetermined size by crushing operation of the crushing device 20 under the water supply from the sink faucet 16, that is, under the supply of sink drainage, and the crushed raw food. Garbage is conveyed to the drain side trap section 28 through the drain pipe 26 together with the sink drain.

In this embodiment, since the garbage is crushed into a rough cut state, most of the garbage stays in the drain side trap portion 28.
When the accumulation amount reaches the set accumulation amount, the upper end portion of the siphon tube 44 is lowered by the elevating drive device 52 as shown in FIG.
When the upper end of the siphon tube 44 is lowered, the sink drainage, that is, the transport water in the water storage tank 37 that is full of water flows into the siphon tube 44 and the inside of the siphon tube 44 becomes full. The transported water stored in the water storage tank 37 is discharged to the drain pipe 26 side at once, and the crushed garbage remaining in the drain side trap portion 28 is drained by the momentum of the discharge. The side trap part 28 is washed away to the downstream side, and the inside of the drain side trap part 28 is cleaned.

If the vent pipe 66 is not provided during the siphon action by the siphon pipe 44, a negative pressure is generated inside the water storage tank 37, and the smooth siphon action is hindered by the negative pressure or is provided in the inflow pipe 35. The sealed water in the inflow side trap portion 36 is drawn into the water storage tank 37, and the inflow side trap portion 36 may be cut out of the sealed water, resulting in a broken state.
However, in the present embodiment, the ventilation pipe 66 that connects the drain pipe 26A and the water storage tank 37 is provided, and since the air is supplied into the water storage tank 37, such inconvenience does not occur, and the water storage tank 37 by siphon action is generated. There is no inconvenience that the transport water in the inside is smoothly discharged and the sealed water in the inflow side trap section 36 is drawn into the water storage tank 37.

  Now, when the transport water in the water storage tank 37 is discharged by the siphon action, the control unit 68 activates the lifting / lowering drive device 52 again to raise the upper end of the siphon tube 44 to its original height again. Returned to

  As described above, in this embodiment, since the inflow side trap portion 36 is provided between the water storage tank 37 and the sink 12, the water storage tank 37 becomes dirty and odors due to the dirty water flowing into the water storage tank 37. Even when the odor is emitted, the odor is effectively prevented from flowing back to the sink 12 side.

  In the present embodiment, since the water transported in the water storage tank 37 is discharged by the siphon action of the siphon tube 44, a discharge valve for discharging the water transported in the water storage tank 37 is provided. It is not necessary to provide an opening / closing mechanism for opening and closing the apparatus, and the apparatus configuration can be simplified.

  Moreover, in this embodiment, the conveyance water stored in the water storage tank 37 is discharged from the water storage tank 37 at once, so that the inside of the drain side trap part 28 can be wiped out, and the drain side trap part 28 is crushed. It is possible to effectively prevent a large amount of garbage from being accumulated and clogging of the drainage pipe 26A due to the accumulation.

  Further, in the present embodiment, the siphon action by the siphon tube 44 is not spontaneously generated, but the siphon action is forcibly caused by the elevating drive device 52, so that the transport water is discharged at an appropriate timing. It is possible to discharge, and the transport water in the water storage tank 37 can be used efficiently for transporting garbage in the drain side trap section 28, and a large amount of transport water stored in the water storage tank 37 is wasted. It is possible to avoid consumption.

  Further, since the upper end portion of the vent pipe 66 is connected to the upper end portion of the water storage tank 37 so that the vent pipe can also function as the overflow pipe 66, a large amount of sink drainage flows into the water storage tank 37 at a time. It is possible to effectively prevent the siphon action from unintentionally occurring and wastefully consuming the transport water.

  Further, in this embodiment, a sensor 50 for detecting the amount of garbage deposited is provided in the drain side trap section 28, and when the amount of garbage deposited reaches the set accumulation amount, this is automatically transferred to the drain side by the transport water. Since it is made to wash away from trap part 28, it can prevent well that garbage after crushing accumulates in drain side trap part 28 excessively.

In the above description, when the sensor 50 detects that a set amount of garbage has accumulated in the drain-side trap portion 28, the transport water in the water storage tank 37 is discharged by a siphon action. In conjunction with the crushing operation, the transport water in the water storage tank 37 can be discharged by a siphon action.
When the crushing device 20 performs the crushing operation, the garbage after crushing flows into the drain side trap portion 28, and accordingly, the conveyance water is discharged in conjunction with the crushing operation of the crushing device 20. By doing so, it is possible to effectively prevent garbage from being crushed in the drain trap part 28.

  Here, when the discharge of the transport water is interlocked with the crushing operation of the crushing device 20, the transport water can be discharged when the set time has elapsed after the crushing device 20 performs the crushing operation, or the crushing operation can be performed. When the operation is finished, the water can be discharged at that timing or after a set time.

In the present embodiment, since the diameter of the siphon tube 44 is smaller than that of the branch tube (preferably half or less), the siphon action can be effectively induced.
Further, since the vent pipe 66 is connected to the upper end portion of the water storage tank 37 and the vent pipe 66 also serves as an overflow pipe, when the upper end portion of the siphon pipe 44 is raised by the elevating drive device 52, the siphon pipe 44. Even when the upper end of the storage tank 37 is lifted above the upper end of the water storage tank 37, there is an advantage that it is possible to satisfactorily prevent the transport water in the water storage tank 37 from entering the inflow conduit 35A. .

  FIG. 7 shows another embodiment of the lifting drive device 52. In this example, a reel 70 is rotated by a motor 60, and thereby a wire 72 such as a wire for suspending the upper end portion of the siphon tube 44 is provided. In this example, the upper end of the siphon tube 44 is moved up and down by winding or rewinding.

In the above embodiment, the upper and lower ends of the siphon tube 44 are driven up and down by the elevating drive device 52, thereby forcibly causing the siphon action to discharge the transport water in the water storage tank 37. FIG. When the siphon tube 44 is provided in a fixed state as shown in FIG. 4, when the sink drainage flows spontaneously, that is, when a large amount of sink wastewater flows into the water storage tank 37 at once, the siphon action is caused at that timing to store the water. It is also possible to discharge the transport water in the tank 37.
In this case, it is also possible to connect the ventilation pipe 66 to the inflow pipe 35, more specifically to the secondary side, that is, the downstream side of the inflow side trap portion 36 instead of the water storage tank 37.

  Furthermore, as shown in FIG. 9, a jet nozzle 74 is provided in the drain side trap portion 28, a water flow is jetted from the jet nozzle 74, and the garbage after crushing collected in the drain side trap portion 28 is forced. For example, it is possible to push it out downstream and discharge it.

Although the embodiment of the present invention has been described in detail above, this is merely an example.
For example, the angle θ (see FIG. 5) of the branch pipe 46 with respect to the vertical portion of the drain pipe 26 can be set to an angle of 0 to 80 °, preferably 30 to 60 °. The flow rate of the inflowing conveyance water can be increased, and the garbage in the drain side trap part 28 can be carried out from the drain side trap part 28 with a small amount of water.

Further, the branch pipe 46 can be provided in the same plane as the vertical portion of the drain pipe 26, more specifically, the plane passing through the axial center thereof forms the same plane.
Also in this case, the flow rate of the inflow of the conveyance water from the branch pipe 46 to the drain pipe 26 can be increased, and the garbage in the drain side trap section 28 can be carried out with a small amount of water.

Alternatively, when the crushing device 20 starts crushing operation and stops for some reason (by the intention of the user or due to a failure of the crushing device 20) before reaching the specified operation time, It is also possible to automatically discharge the transport water.
In addition, this invention can be comprised in the form which added the various change in the range which does not deviate from the meaning.
