The present invention relates to a disposer that pulverizes and discharges soot, a drainage system including the disposer, and a method for cleaning the drainage system.

Disposers have been widely used in apartment buildings such as condominiums in consideration of reducing garbage in the kitchen of ordinary households, improving the cleanliness of the kitchen, and reducing the environmental burden. Disposers for general households are installed under kitchen sinks, and have a structure that can crush raw garbage that has flowed into the disposer together with tap water and flow the crushed raw garbage along with tap water into the sewer. Yes.

In general household disposers, garbage that has flowed into the disposer is blown toward the inner wall of the disposer by a rotating plate that rotates at a high speed in the disposer. Subsequently, the garbage is crushed by a hammer installed at the upper edge portion of the rotating plate and a fixed blade provided on the inner wall of the disposer. Thereafter, the crushed raw garbage is discharged from the discharge port of the disposer toward the piping of the drainage system by the rotation of the impeller installed on the lower surface of the rotating plate.

For example, Patent Documents 1 and 2 disclose a structure of a general household disposer, a cleaning method in the disposer, and a drainage system including the disposer. In particular, in Patent Document 1, an air passage that communicates a crushing chamber and a discharge chamber divided in the vertical direction by a rotating plate is closed with tap water flowing from above, and is temporarily stored in the crushing chamber by air pressure in the discharge chamber. In addition to storing the tap water and restarting the disposer, the inside of the disposer is washed and the tap water is drained all at once to clean the inside of the pipe.

On the other hand, in Patent Document 2, a wash water storage tank capable of supplying tap water to an S-shaped trap or a siphon drain pipe connected downstream of the disposer or the disposer is installed. Moreover, in patent document 2, the structure which drains a tap water from the said wash water storage tank after completion | finish of operation | movement of a disposer is employ | adopted. As a result, the amount of water required to cause the siphon phenomenon does not become insufficient, and the siphon phenomenon can be easily generated.

<Example>
First, with reference to FIG. 1 thru | or FIG. 4, the drainage system which concerns on an Example, and the disposer used for this are demonstrated in detail. Here, FIG. 1 is a schematic configuration diagram of the drainage system according to the present embodiment, and FIG. 2 is an enlarged schematic configuration diagram in the vicinity of the disposer incorporated in the drainage system according to the embodiment. 3A is a front view of a valve provided in the disposer according to the present embodiment in a closed state, and FIG. 3B is a side view of the valve provided in the disposer according to the present embodiment in a closed state. 4A is a front view of a valve provided in the disposer according to the present embodiment in an open state, and FIG. 4B is a side view of the valve provided in the disposer according to the present embodiment in an opened state.

The drainage system 10 according to the present embodiment is used for each residence of an apartment house such as an apartment. As shown in FIG. 1, as shown in FIG. 1, the drainage system 10 includes a sink 12 in which a water tap 11 is installed, a disposer 13 disposed below the sink 12, and an S located downstream of the disposer 13. The S-shaped pipe 14 and the siphon pipe 15 located downstream of the S-shaped pipe 14 are provided. With such a structure, the drainage system 10 according to the present embodiment drains the kitchen in each home using the siphon phenomenon.

In the present specification, since the vertical direction is the vertical direction, the upper direction is a position in a direction away from the ground, and the lower direction is a position in a direction approaching the ground. Moreover, in this specification, since tap water flows toward the sewer from the sink 12 via the siphon pipe 15, the upstream is a position closer to the sink 12 side, and the downstream is closer to the siphon pipe 15 side. Position.

The water tap 11 is connected to a water pipe (not shown), and the tap water can be poured into the sink 12 by operating the water tap 11. As can be seen from FIG. 1, an opening 12b is formed in the bottom surface 12a of the sink 12, and a disposer 13 is connected to the opening 12b.

As can be seen from FIGS. 1 and 2, the disposer 13 includes a housing 21 that is a main body portion, and a driving unit 22 that generates a rotational driving force that is necessary for crushing the introduced soot in the housing 21. Have. The casing 21 is provided with an introduction part 21a for allowing the introduction of soot and water from the sink 12 into the upper part, and with a discharge part 21b for discharging the crushed soot and water on the lower side surface. In the present embodiment, a cylindrical opening that functions as the introduction portion 21 a is formed on the upstream side of the disposer 13 and connected to the sink 12, and is connected to the S-shaped pipe 14 on the downstream side of the disposer 13. A circular opening (that is, a discharge port) that functions as the discharge portion 21b is formed in the portion.

Here, it is important that the formation position of the discharge port which is the discharge unit 21b is the lower side surface of the housing 21. This is because tap water is discharged from the casing 21 in the horizontal direction by using centrifugal force to rotate a rotating plate and an impeller described later in the casing 21. That is, the formation position of the discharge port which is the discharge unit 21b is not the bottom surface of the housing 21 but the lower side surface of the housing 21 from the viewpoint of the drainage function and the operation of the drainage system 10 and the disposer 13 according to the present embodiment. Become.

As shown in FIG. 1, a lid switch 23 is installed in the introduction part 21 a of the housing 21. When introducing soot and water into the disposer 13, the lid switch 23 is removed. When the disposer 13 is driven, the lid switch 23 is rotated while fitting the lid switch 23 in the introducing portion 21a to match the desired orientation, and the disposer 13 is turned on. In addition, by providing an opening in the lid switch 23 or forming a gap between the lid switch 23 and the introduction portion 21a, the tap water can be discharged even when the lid switch 23 is installed in the introduction portion 21a. 13 can be introduced.

As shown in FIG. 2, a disk-shaped rotating plate 24 is provided in the substantially cylindrical internal space of the casing 21. The rotating plate 24 is provided below the central portion of the housing 21 so as to be parallel to the inner bottom surface 21 d of the housing 21 while being separated from the inner side surface 21 c of the housing 21. That is, the diameter of the rotating plate 24 is smaller than the diameter of the internal space of the housing 21. Due to the arrangement of the rotating plate 24, the internal space of the housing 21 is divided in the vertical direction into a crushing chamber 25 located on the introduction portion 21a side and a discharge chamber 26 located on the discharge portion 21b side. . Here, the crushing chamber 25 and the discharge chamber 26 communicate with each other through a gap between the rotating plate 24 and the inner side surface 21 c of the housing 21.

Further, as shown in FIG. 2, a plurality of hammers 27 for pulverizing the introduced soot are provided at the edge portion of the first surface 24a of the rotating plate 24 located on the crushing chamber 25 side. On the other hand, a plurality of impellers 28 for discharging tap water stored in the discharge chamber 26 and pulverized soot are provided on the second surface 24b of the rotating plate 24 located on the discharge chamber 26 side. Furthermore, an annular fixed tooth 31 for pulverizing the introduced soot is provided on the inner side surface 21c of the housing 21 so as to surround the periphery of the rotating plate 24 at a distance.

And as shown in FIG. 2, the discharge part 21b of the housing | casing 21 is provided with the valve 32. As shown in FIG. More specifically, the valve 32 is disposed so as to close a circular opening that functions as the discharge portion 21 b of the housing 21. By providing the valve 32 in this way, tap water can be stored in the discharge chamber 26 upstream of the valve 32.

As shown in FIGS. 3A and 3B, the valve 32 has a substantially disk shape so as to close the circular opening that functions as the discharge portion 21b. The valve 32 includes an annular fixing portion 32a that is fixed in contact with the housing 21 in the discharge portion 21b, and an opening / closing portion 32b formed in an inner region surrounded by the fixing portion 32a. . Furthermore, the opening / closing part 32b is divided into two by cutting, and if the applied water pressure value is less than a predetermined value, the opening / closing part 32b is closed (FIG. 3A, FIG. 3B), and when the applied water pressure value exceeds the predetermined value. The opening / closing part gradually opens (FIGS. 4A and 4B). In particular, when the valve 32 is open, the central portion of the valve 32 opens greatly and opens toward the edge of the valve 32.

Accordingly, the valve 32 in the present embodiment is closed when the amount of tap water stored in the discharge chamber 26 is less than a predetermined amount, and when the amount of stored tap water exceeds a predetermined amount, As it increases, it opens automatically and gradually. In other words, the valve 32 controls the storage amount of tap water and the discharge amount of tap water in the discharge chamber 26.

In addition, as the material of the valve 32, various materials can be used as long as the above opening and closing can be performed. Further, the material and the material of the valve 32 can be appropriately determined depending on the amount of tap water to be stored in the discharge chamber 26 and the amount of tap water required to make the siphon phenomenon easy to occur in a short time. . That is, the material and material of the valve 32 can be appropriately determined according to various dimensions of the drainage system 10 such as the dimensions of the disposer 13, the dimensions of the discharge chamber 26, the dimensions of the S-shaped pipe, and the dimensions of the siphon pipe 15. . Furthermore, the shape of the valve 32 is not limited to that shown in FIGS. 3A, 3B, 4A, and 4B, and various shapes can be adopted as long as the opening and closing can be performed.

As shown in FIG. 2, the drive unit 22 includes a motor 22a and a drive shaft 22b that transmits the rotational drive force of the motor 22a to the rotary plate 24. The drive unit 22 is fixed to the lower side of the housing 21 by a fixing member 33. The drive shaft 22 b passes through a through hole that penetrates the bottom of the housing 21 and is connected to the rotating plate 24. The drive shaft 22b is provided with a rotating body (not shown) that rotates inside, and a covering member (not shown) is provided so as to cover the rotating body apart. . Thereby, the said covering member contacts the housing | casing 21, tap water will not leak from a through-hole, and also the driving force of the motor 22a will be transmitted to the rotating plate 24, without being inhibited.

The structure and arrangement position of the drive unit 22 are not limited to those described above, and other structures can be used as long as the rotating plate 24 is reliably rotated and tap water does not leak from the housing 21. It may be adopted or installed in other areas.

As shown in FIG. 1, one end of the S-shaped pipe 14 is connected to the housing 21 at the discharge portion 21 b of the disposer 13, and the other end is in a space formed between the indoor floor 34 and the floor slab 35. The siphon pipe 15 is connected. The S-shaped pipe 14 includes a horizontal portion 14a extending in the horizontal direction from the discharge portion 21b of the housing 21, a first elbow portion 14b bent in the vertical direction from the horizontal direction downstream of the horizontal portion 14a, and a first elbow portion 14b. An S-shaped drain trap 14c arranged downstream, a vertical portion 14d extending in the vertical direction from the drain trap 14c, and a second elbow portion 14e bent in the horizontal direction from the vertical direction downstream of the vertical portion 14d. ing.

Due to the trap structure of the S-shaped pipe 14, tap water is always present in the drain trap 14 c, blocking odors and various gases from the sewer, and sanitary pests and rats intruding indoors. Is preventing. The horizontal portion 14a functions as a connecting pipe that connects the discharge portion 21b of the housing 21 and the drain trap 14c.

As shown in FIG. 1, the siphon pipe 15 is connected to the second elbow part 14e of the S-shaped pipe 14 and connected to the other end of the siphon horizontal pipe 15a extending in the horizontal direction and the siphon horizontal pipe 15a. The elbow pipe 15b is composed of a siphon vertical pipe 15c extending vertically from the elbow pipe 15b. The siphon horizontal pipe 15 a extends in parallel with the indoor floor 34 and the floor slab 35 in the space between the indoor floor 34 and the floor slab 35. That is, the siphon horizontal pipe 15a is installed with no gradient. Thereby, in the drainage system 10 of the present Example 10, the underfloor height can be made small. The siphon vertical pipe 15c is connected to a common drain pipe (not shown) of the apartment house extending in the vertical direction.

According to such a structure of the siphon pipe 15, when tap water flows from the siphon horizontal pipe 15a to the siphon vertical pipe 15c via the elbow pipe 15b, the tap water falls by its own weight in the siphon vertical pipe 15c. A siphon phenomenon will occur. When the siphon phenomenon occurs, drainage in the S-shaped pipe 14, the siphon horizontal pipe 15a, the elbow pipe 15b, and the siphon vertical pipe 15c is induced, and drainage to the common drain pipe of the apartment house described above is promoted. .

Next, a method for cleaning the drainage system according to the present embodiment will be described in detail with reference to FIGS. Here, FIG. 5 thru | or FIG. 7 is an expansion schematic block diagram for demonstrating the washing | cleaning process of this drainage system shown similarly to FIG.

First, in a state where the disposer 13 is stopped, tap water is introduced from the sink 12 into the internal space of the casing 21 through the introduction portion 21a of the casing 21 (FIG. 5: water introduction step). For example, the water introduction process may be performed only for cleaning the drainage system 10, but in general, tap water is used by washing tableware or ingredients in the sink 12, so that the water introduction process is performed. Will be done. That is, the water introduction process is performed by performing a general water operation in the kitchen.

Next, the tap water introduced in the water introduction step is stored in the discharge chamber 26 which is a storage space surrounded by the casing 21, the rotating plate 24, and the valve 32 provided in the discharge portion 21b (FIG. 6: Water storage process). More specifically, the introduced tap water reaches the rotating plate 24, and further passes through a gap between the rotating plate 24 and the side surface of the housing 21, so that the introduced tap water reaches the discharge chamber 26. Will be stored. Here, the amount of stored tap water should be as large as possible, and even if it is too large, the tap water does not overflow into the sink 12 by the valve 32 automatically opening according to the water pressure. . In addition, even when the amount of tap water supplied is small, the valve 32 will be kept closed, and by performing general kitchen work such as washing dishes or ingredients in the sink 12 A plurality of water introduction processes are performed, and tap water is always stored so that the discharge chamber 26 is completely immersed. In addition, by adjusting the opening / closing characteristics of the valve 32, the valve 32 may be opened before the discharge chamber 26 is completely immersed in tap water, and the amount of tap water stored in the discharge chamber 26 may be adjusted.

Next, the disposer 13 is driven by adjusting the lid switch 23 of the disposer 13 to a desired position. Thereby, the drive part 22 drives, the rotating plate 24 is rotated, the tap water stored by the impeller 28 is stirred, and centrifugal force is added to the stored tap water (FIG. 7: stirring process). And the tap water stored by the said centrifugal force is discharged | emitted at a stretch via the discharge part 21b, the S-shaped piping 14, and the siphon piping 15 (FIG. 7: discharge | emission process). Thereby, the flow rate of tap water in the siphon horizontal pipe 15a can be increased and the tap water can be caused to flow through the siphon vertical pipe 15c, and the siphon phenomenon can be caused in a short time. When the siphon phenomenon occurs, the crushed material of the disposer 13 remaining in the siphon pipe 15 can be washed away, and the drainage system 10 can be cleaned well.

In the drainage system 10 and the disposer 13 according to the present embodiment, a valve 32 that controls the amount of tap water stored in the discharge chamber 26 and the amount of tap water discharged is provided in the discharge unit 21b. For this reason, the tap water required for the siphon phenomenon can be always stored in the discharge chamber 26 by performing a general water operation in the kitchen even after the use of the disposer 13. That is, the siphon phenomenon can be easily caused in a short time by such a structure and operation effect of the valve 32. In addition, since the siphon phenomenon can be caused more reliably and in a short time only by the simple structure of the valve 32, the cost of the drainage system 10 and the disposer 13 can be reduced and the maintenance can be facilitated.

Furthermore, the valve 32 according to the present embodiment is closed when the amount of tap water stored in the discharge chamber 36 is less than a predetermined amount, and when the amount of stored tap water exceeds a predetermined amount, the amount of stored tap water increases. Open automatically and gradually. Thereby, the structure which controls the valve 32 becomes unnecessary, and the drainage system 10 and the disposer 13 can be further reduced in cost and easier to maintain.

In this embodiment, the valve 32 automatically opens and closes according to the water pressure. However, a valve that can be opened and closed by electronic control or mechanical control may be provided. Furthermore, when performing the electronic control, the amount of water stored in the discharge chamber 26 may be detected by a sensor or the like, and the opening / closing control of the valve may be performed according to the detection result. In addition, a discharge portion 21b that is a discharge port is formed on the lower side surface of the casing 21, and the casing 21 itself does not protrude in the horizontal direction. However, the casing 21 protrudes in the horizontal direction from the lower side surface. A discharge pipe may be formed, and the S-shaped pipe 14 may be connected to the discharge pipe that is a part of the housing 21 (that is, the disposer 13).

<Modification>

Therefore, in the modification shown in FIG. 8, tap water is stored in the storage space formed by the internal region of the discharge pipe 42 upstream of the discharge chamber 26 and the valve 32. That is, in the modification shown in FIG. 8, the storage space for storing tap water is larger by the amount of the discharge pipe 42, unlike the embodiment described above.

In the modification shown in FIG. 9, the valve 32 is provided in the S-shaped pipe 14. That is, the valve 32 is not limited to being installed in the disposer 13 and may be installed in a pipe located downstream of the disposer 13. Therefore, in the modification shown in FIG. 9, tap water is stored in a storage space formed by a partial internal region of the S-shaped pipe 14 upstream of the discharge chamber 26 and the valve 32. That is, in the modification shown in FIG. 9, the storage space for storing the tap water is different from the above-described embodiment, and is increased by the area of a part of the S-shaped pipe 14.
