[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a human body local cleaning device for cleaning a human body local part with warm water.
[0002]
[Prior art]
A conventional human body local cleaning apparatus will be described with reference to FIG. 4. The human body local cleaning apparatus includes an instrument body 1 having a cleaning device such as a hot water tank and a cleaning nozzle (not shown) therein, and the instrument body. 1 consists of a toilet lid and a toilet seat that are pivotally connected to 1 and placed on a toilet. The appliance main body 1 has a water supply port 3 for taking water for local cleaning into the appliance main body 1, and the water supply port 3 extends from a branch plug provided in a water supply source. The water supply pipe 2 is connected.
[0003]
The water supply pipe 2 and the water supply port 3 are connected through a seal member 5 such as an O-ring. A fastening member 4 such as a cap nut provided in the water supply pipe 2 and a screw provided in the water supply port 3 are connected to a spanner or the like. This is done by screwing using a tool.
[0004]
[Problems to be solved by the invention]
However, the use of a tool when connecting the water supply pipe 2 and the water supply port 3 can easily perform the tightening operation. However, if excessive tightening is performed, the screw or the fastening member 4 is damaged, It will cause a leak. Moreover, in order not to perform excessive tightening, even if it is attempted to connect without using a tool, the fastening member 4 that is normally used uses a cap nut of about 10 to 20 mm HEX, so use a hand directly. Therefore, it is difficult to connect so that there is no looseness, which causes the cause of water leakage.
[0005]
The present invention has been made in view of the above-described problems, and when performing a connection work between the water supply pipe 2 and the water supply port 3, a human body local cleaning that can be connected without loosening without using a tool such as a spanner. The object is to provide a device.

[0007]
DETAILED DESCRIPTION OF THE INVENTION
The resin cylindrical body 6 used in the present invention is preferably a resin molded product having a high elastic modulus, and preferably, polypropylene, polystyrene, polyamide, or the like can be used. Moreover, as shown in FIG. 3, it is preferable to provide an unevenness | corrugation in the outer periphery along the direction (refer FIG. 1) which connects the water supply piping 2 and the water supply port 3. As shown in FIG. The unevenness plays a role of preventing slip when the resin tubular body 6 is directly rotated by hand to perform the connection work.
[0008]
As shown in FIG. 2, a fitting piece 8 is preferably provided on the inner periphery of the resin tubular body 6, and a fitting guide 9 is preferably provided on the outer periphery of the water supply port 3. By fitting the fitting guide 9, it is possible to prevent the fastening member 4 fitted to the resin tubular body 6 from being loosened.
[0009]
As shown in FIG. 5, the outer peripheral shape of the fastening member 4 and the inner peripheral shape of the resin tubular body 6 are preferably polygonal, and further circumscribe the polygon of the fastening member 4. It is preferable that the diameter (R1) of the virtual circle is larger than the diameter (R2) of the virtual circle inscribed in the polygon of the resin tubular body 6 (R1> R2). The fact that each other is polygonal and the dimensional relationship R1> R2 can prevent the resin-made cylindrical body 6 from sliding in the circumferential direction.
[0010]
The dimensions of the resin cylindrical body 6 are preferably 25 mm or more in diameter and 5 mm or more in length, and more preferably 30 to 100 mm in diameter and 20 to 100 mm in length from the viewpoint of ease of gripping and generated torque. Furthermore, by providing the removal prevention protrusion 10 (see FIG. 2) separately from the above-described fitting piece 8 on the inner periphery of the resin tubular body 6, the resin tubular body 6 is more likely to fall off. It is possible to reliably prevent the fastening member 4 from being overtightened.
[0011]
The fastening member 4 used in the present invention is not particularly limited as long as it is a member that can connect the water supply pipe 2 and the water supply port 3, but a metal cap nut is preferably used. In addition, it is possible to use one provided with a male screw that is inserted into the water supply port 3 and screwed.
[0012]
【Example】
Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is an enlarged cross-sectional view of a connecting portion between the water supply pipe 2 and the water supply port 3 showing an embodiment of the present invention. The water supply pipe 2 is fitted with a 15 mm HEX cap nut as a fastening member 4 and the cap nut. The inner peripheral shape is a polygon having twelve protrusions, and the resin cylindrical body 6 provided with irregularities on the outer peripheral surface and the fitting pieces 8 and the removal preventing protrusions 10 on the inner peripheral surface is attached. . On the other hand, the water supply port 3 has a projection that forms a fitting guide 9 on its outer periphery and a threaded portion that is screwed into the aforementioned cap nut.
[0013]
As shown in FIG. 1, the water supply pipe 2 and the water supply port 3 are connected by sandwiching an O-ring that is a seal member 5 and directly rotating the resin cylindrical body 6 by hand to obtain a cap nut (not shown). ) And the water supply port 3 are screwed together. As shown in FIG. 3, since the resin tubular body 6 is provided with the prevention protrusions 10, the resin tubular body 6 is not over-tightened, and once fitted, When the joining piece 8 and the fitting guide 9 are fitted, the joined portion is not loosened.
[0014]
As shown in detail in FIG. 2, the connecting member 7 shown in FIG. 1 is a pipe whose inside is a through hole for water passage, and is aligned when inserted into the water supply port 3. Is provided so as to protrude from the end of the resin tubular body 6.
[0015]
【The invention's effect】
In the present invention, the water pipe and the water inlet can be directly used by hand without using a tool such as a spanner by fitting the resin tubular body to the fastening member already provided in the water pipe. It is possible to provide a human body local cleaning device that does not cause water leakage due to excessive tightening and that does not cause water leakage due to loosening. Furthermore, by projecting the connecting member 7 from the end of the resin cylindrical body 6, even if the connecting portion cannot be directly visually observed, it is easy to perform alignment by groping.
