Description

  The present invention relates to a discharge pipe joint for a disposer attached to a sink drain port.

  The disposer was invented in the United States in 1927 and is attached to a sink for crushing and treating kitchen waste together with kitchen wastewater, and has the advantage that it can be discharged on the spot. It began to spread in Japan from around 1980s, but in the 1980s, local governments prohibited the installation and use of disposers alone due to ordinances and other reasons because of the increased burden on the sewerage system.

In recent years, since the garbage problem has become a serious social problem, research and development of a garbage recycling system using a disposer has progressed, and instead of disposing the disposer alone, the garbage is crushed and then discharged as wastewater and purified. Commercialization of disposer garbage disposal systems that are later discharged into sewers and merged septic tanks is accelerating. In this system, although garbage is finely pulverized with a disposer, it is large and solids up to about 10 mm will be discharged, but the drainage pipe uses conventional traps and drainage pipes. The current situation is. In other words, in traps used in normal drainage facilities, the solid matter crushed from the garbage tends to accumulate in the trap for structural and functional reasons, and the trap becomes clogged in the worst state. There was a point.

  The disposer discharge pipe joint is a joint that connects the disposer installed at the sink drain and the kitchen drain pipe. There is what is called a trap between the discharge pipe joint and the kitchen drain pipe, and various types are generally used. When used as a disposer, an S-shaped trap or P A character trap is common.

  FIG. 4 is an explanatory view of a conventional disposer discharge pipe joint and a trap, and is an explanatory view showing an installed state of the disposer discharge pipe joint and a trap. In the figure, 1 is a pipe as a disposer discharge pipe joint, 2 is a trap (S-type trap), 3 is a disposer discharge port, 4 is a drain pipe connecting portion, and 5 is a disposer body.

  FIG. 5 is an explanatory diagram of traps used in a conventional disposer, and generally shows trap types (A) to (F) used in the disposer. There is a standard that these traps must always have a sealing depth of 50 mm or more so that the odor on the drain pipe side does not flow back to the sink side (Japan Water Supply and Sanitation Engineering Association Standard; HASS206). For this reason, when the garbage pulverized product by the disposer is discharged, there is a problem that solid matter is deposited on the sealed water portion, or is easily attached to the inner wall surface, and in the worst case, it is blocked. For this reason, conventionally, the wastewater flowing into the trap is swirled by providing a spiral groove on the inner surface of the trap or providing a guide guide on the inner surface of the trap inlet so that the wastewater flowing into the trap becomes a swirling flow. Although it has been conceived to be a streamlined device, it has been very difficult to manufacture because it has a complicated structure for commercialization.

In view of the above, an object of the present invention is to provide a discharge pipe joint for a disposer that can prevent the garbage trapped in the drain trap from partially accumulating and blocking in the worst case.

  The present invention is a discharge pipe joint for a disposer attached to a disposer discharge port that is attached to a sink discharge port and crushes garbage together with drainage, and is a horizontal pipe from the disposer discharge port and a vertical pipe for drainage The disposer drainage was made to flow out while spirally turning the inner wall of the pipe in the vertical direction.

  ADVANTAGE OF THE INVENTION According to this invention, the waste pipe | tube joint for disposables which can prevent that the garbage which was grind | pulverized with the disposer partially accumulates in a drain trap, and is obstruct | occluded in the worst case is realizable.

  The invention according to claim 1 is a discharge pipe joint for a disposer attached to a disposer discharge port that is attached to a sink drain port and crushes garbage together with drainage, and is used for horizontal piping and drainage from the disposer discharge port Displace the central axis so that the vertical pipe of the pipe is aligned with the direction of rotation of the disposer (counterclockwise for counterclockwise rotation, clockwise for clockwise rotation). It is designed to flow while spiraling the inner wall, thereby effectively washing the solid matter that accumulates and adheres to the drainage trap with the wastewater discharged from the disposer, and prevents the accumulation of solid matter, etc. it can.

  The invention according to claim 2 is the discharge pipe joint for disposer according to claim 1, wherein the horizontal pipe has a downward slope in the flow direction, and thereby the effect of increasing the flow rate of the disposer drainage is obtained. Therefore, it is easy to form a sufficient swirling flow, and a further cleaning effect is obtained.

(Embodiment)
The best mode of the present invention will be described below. 1 is a side view of a discharge pipe joint for a disposer according to an embodiment of the present invention, FIG. 2 is a cross-sectional view of the discharge pipe joint for a disposer according to an embodiment of the present invention, and FIG. 3 is an embodiment of the present invention. It is explanatory drawing of the usage example of the discharge pipe coupling in. The same elements as those in the conventional example shown in FIG. 6 is a cleaning mouth with a lid.

  In FIG. 1, a horizontal pipe 1 from a disposer discharge port 3 is connected to a vertical pipe 7 for drainage with a descending gradient equal to or greater than the reciprocal of the pipe diameter from the horizontal in the flow direction. The pipe diameter is 40A or 50A, and the horizontal pipe gradient from the disposer discharge port 3 is greater than or equal to the inverse of the pipe diameter (1/40 or 1/50).

  FIG. 2 shows a cross-sectional view taken along the line AA in the horizontal direction of FIG. As shown in FIG. 2, the horizontal pipe 1 from the disposer discharge port 3 is in a direction in accordance with the rotational direction of the disposer with respect to the vertical pipe 7 connected to the drain pipe (in the case of left rotation). The pipes are connected in a T shape by shifting the central axis of each pipe (counterclockwise and clockwise in the case of right rotation). The center axis deviation width is preferably 1/3 to 1/2 of the pipe diameter, but the drainage direction of drainage intersects the pipe wall at an obtuse angle with respect to the vertical pipe 7, and the outflow rate is not reduced or the outflow is not hindered. Similarly, there is no particular limitation as long as it is smoothly connected in the circumferential direction of the pipe 7 in the vertical direction.

In addition, the direction of deviation of the central axis (right direction or left direction) is the direction in accordance with the disposer rotation direction so that the drainage speed discharged from the disposer is not reduced or the drainage is not hindered, that is, left It is necessary to shift the center axis in the case of rotation in the counterclockwise direction and in the clockwise direction in the case of right rotation.

  With the above structure, the drainage discharged from the disposer discharge port 3 flows out along the horizontal pipe 1, and when the horizontal pipe 1 has a downward slope, the outflow speed is further accelerated while the vertical flow is accelerated. Smoothly flows in the circumferential direction of the pipe 7 in the direction, changes direction from the horizontal direction to the vertical direction, and is spirally discharged along the inner wall surface of the pipe 7 in the vertical direction.

  As a result, as shown in FIG. 3, in the configuration having the discharge trap 8 connected immediately after the T-shaped or Y-shaped discharge pipe joint, the drainage discharged spirally from the T-shaped discharge pipe joint. By flowing into the drain trap 8 as it is, it is possible to effectively wash the solid matter such as the pulverized garbage by the disposer deposited on the bottom of the sealed water of the drain trap 8 and prevent the deposition of the solid matter.

  The present invention is not limited to a disposer, and even when a drain trap is installed on the downstream side of such devices as kitchen drainage, washbasin, bath, toilet, etc. in general drainage facilities, the drainage becomes a swirling flow. Therefore, the solid matter accumulated in the drainage trap has a great effect of discharging and cleaning, so that it can be industrially used as a drainage pipe joint for these general drainage devices.
