Technical Field
The present invention relates to a flush toilet, and more particularly, to a flush toilet for washing a toilet with wash water.
Background
Conventionally, for example, as described in patent document 1, a flush toilet is known which includes a bowl portion and a rim spout portion for spouting flush water along a rim portion, and in which the bowl portion is washed by a swirling flow of the flush water spouted from the rim spout portion along the rim portion.
More specifically, in patent document 1, a water conduit for guiding washing water to a rim spout port (into a bowl portion) has, as a starting point, a water supply unit (branch unit) for supplying water to the water conduit: a 1 st water guide part extending to the left and right sides of the basin part; and a 2 nd water guide part extending to the other side of the left and right sides of the basin part. The water supply portion is provided at the center of the tub portion.

Disclosure of Invention
In recent years, further miniaturization of flush toilets has been studied in order to further improve design. For example, a flush toilet in which a size reduction in the front-rear direction is achieved and a so-called "front protrusion" is small has been studied.
Conventionally, as shown in patent document 1, a water supply unit (branch unit) is provided at the center of the left and right with respect to a bowl unit. The inventors of the present invention have studied to reduce the size of the water supply unit (branch unit) in the front-rear direction by arranging the water supply unit at a position offset to either the left or right with respect to the bowl unit.
The present invention has been made in the context of the above. The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a flush toilet that can be downsized in the front-rear direction.
The present invention is a flush toilet, including: a toilet main body defining a bowl portion; and a water conduit formed inside the toilet main body for guiding the washing water into the bowl portion, wherein the water conduit has, as a starting point, a water supply portion for supplying water to the water conduit: a 1 st water guide part extending to a 1 st water spouting port arranged on one of left and right sides of the bowl part; and a 2 nd water guide portion extending to a 2 nd water spouting port disposed on the other of the left and right sides of the bowl portion, the water supply portion being disposed at a position deviated to either of the left and right sides with respect to the bowl portion, and a water supply direction to the water supply portion being a direction inclined in a front-rear direction and intersecting with an inner side surface of the water supply portion in a plan view.
According to the present invention, the water supply portion is provided at a position offset to either the left or right with respect to the bowl portion, and therefore the flush toilet can be downsized in the front-rear direction.
In the present invention, the ratio (distribution ratio) of the amount of water guided to the 1 st water guide (i.e., the amount of water discharged from the 1 st water discharge port) to the amount of water guided to the 2 nd water guide (i.e., the amount of water discharged from the 2 nd water discharge port) may be adjusted to a desired value by adjusting the angle of water supply to the water supply portion.
Preferably, the water supply direction to the water supply unit is a direction substantially orthogonal to a tangential direction of an inner surface of the water supply unit. In the present specification, the substantially orthogonal expression means about 75 ° to 105 °.
In a preferred example of the specific configuration, the water supply to the water supply unit is performed by a linear nozzle inclined in a front-rear direction in a plan view and extending in a direction intersecting an inner surface of the water supply unit, and the linear nozzle is connected to a water supply pipe having: a root end portion extending in the front-rear direction; a tip portion connected to the linear nozzle and extending in the same direction as the linear nozzle; and a bending portion bent from the root end portion to the tip end portion.
In such an example, the nozzle can be mounted relatively easily, and the space for the nozzle installation site can be reduced.
Alternatively, in another preferred example, the water supply to the water supply unit is performed by a bent nozzle, and the water supply unit includes: a root end portion extending in the front-rear direction; a tip portion extending in a direction intersecting with an inner side surface of the water supply portion, the tip portion being inclined in a front-rear direction in a plan view; and a bending portion which is bent from the base end portion to the tip end portion, and to which a water supply pipe extending in a front-rear direction is connected.
In such an example, the nozzle can be easily attached, and the space for the nozzle installation site can be reduced.
Alternatively, in a further preferred example, the water supply to the water supply unit is performed through a water supply passage extending in a direction intersecting with an inner side surface of the water supply unit while being inclined in the front-rear direction in a plan view, and the water supply passage is connected to a water supply pipe via a buffer chamber in which the washing water can temporarily stay.
In such an example, since the washing water can temporarily stay in the buffer chamber, the influence of the water supply direction from the water supply pipe to the buffer chamber can be reduced, and the water can be supplied to the water supply portion in the direction of the water supply path with higher accuracy.
In this case, it is more preferable that the buffer chamber has a wall formed at a position facing a water supply direction of the washing water from the water supply pipe into the buffer chamber.
This can further reduce the influence of the water supply direction from the water supply pipe to the buffer chamber, and can supply water to the water supply portion with higher accuracy in the direction of the water supply path.
Preferably, a bottom surface of the buffer chamber is inclined toward the water supply unit.
This can suppress the retention of residual water in the buffer chamber.
According to the present invention, the water supply portion is provided at a position offset to either the left or right with respect to the bowl portion, and therefore the flush toilet can be downsized in the front-rear direction.
