detailed description

Hereinafter, a human body part washing device 1 according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 6 . In addition, in the following description, the width direction refers to the direction along the width direction of the cleaning nozzle 20 (the X direction shown in the figure), and the front-back direction refers to the direction along the direction in which the cleaning nozzle 20 advances and retreats (the Y direction shown in the figure). direction), and the up-down direction refers to the direction perpendicular to the width direction and the front-back direction (the Z direction shown in the figure). The up-down direction may be a direction along the gravitational direction, or may be a direction inclined at a fixed angle with respect to the gravitational direction as in the present embodiment.

The human body part washing device 1 according to this embodiment includes a base member 10 , a washing nozzle 20 , a hose 30 , a connection part 40 , and a flexible rack 50 . Each configuration will be described in detail below. In addition, the shape etc. of each member refer to the shape etc. when the washer nozzle 20 is located in the original position, except the case where it expressly expresses especially. As shown in FIG. 1 , the human body part cleaning device 1 is arranged behind the toilet seat T, and the nozzle advances during cleaning to clean the user's part. The base member 10 is a member for supporting the respective members, and has a base plate portion 11 attached to the toilet and a support table portion 12 provided above the base plate portion 11 .

Washing nozzle 20 is a member supported by base member 10 so as to be able to move forward and backward. The tip side of the washer nozzle 20 is housed in a nozzle housing case 121 formed in the support table portion 12 . In this embodiment, the washing nozzle for anus and the washing nozzle for women are arranged side by side in the width direction. In addition, the basic difference between the cleaning nozzle for the anus and the cleaning nozzle for women lies in the spraying structure of the cleaning water and the number of connected hoses 30. Except for the cases clearly indicated below, the two cleaning nozzles 20 are not distinguished and are only referred to as " The human body part washing device 1 according to this embodiment will be described with reference to the washing nozzle 20". When the cleaning nozzle 20 is located at the home position (the state shown in FIGS. 2 to 4 ), a part of the tip side is in a state of being housed in the nozzle housing case 121 . When cleaning, it advances through the opening formed at the front end of the nozzle housing case 121 and reaches the cleaning position (the state shown in FIG. 5 ). After reaching the washing position, washing water is sprayed from the washing water ejection port provided at the upper portion of the front end side of the washing nozzle 20 . The washing nozzle 20 in the present embodiment is installed so that the tip side is positioned lower than the base end side and is inclined at a predetermined angle with respect to the horizontal direction.

The hose 30 is a supply pipe for supplying washing water to the washing nozzle 20 and is formed of a deformable material (for example, a rubber material). One end of the hose 30 is connected to the rear of the washer nozzle 20 . In this embodiment, two hoses 30 are connected to the washing nozzle for anus, and one hose 30 is connected to the washing nozzle for women. Two flow paths are formed in the anus washing nozzle, and hoses 30 are respectively connected to them. Thereby, a variety of cleaning methods can be realized by the cleaning nozzle for the anus.

In this embodiment, the two hoses 30 connected to the anus washing nozzle are integrated so as to line up in the width direction. That is, the hose 30 as a whole has a flat shape that is flat in the width direction. In other words, it can be said that the hose 30 is formed by forming two flow paths aligned in the width direction in a flat rubber material. Although not shown, the hose 30 connected to the feminine washer nozzle also has such a flat shape (one flow path).

The other end of the hose 30 is connected to the connection part 40 . The connecting portion 40 is provided on the lower side of the washer nozzle 20 . Specifically, the washer nozzle 20 in this embodiment is installed so that the tip side is positioned below the base end side at a predetermined angle with respect to the horizontal direction, and the connection portion 40 is provided at the center of the gravitational direction on the base end side of the washer nozzle 20 . underside. The connection part 40 in this embodiment is a joint provided in the flow control valve. The connecting portion 40 is in a shape protruding rearward from the main body of the flow regulating valve 41 (see FIGS. 2 to 5 ). In this embodiment, the connecting portion 40 exists along the horizontal direction. Roughly seen, one end of the hose 30 is connected to the cleaning nozzle 20, and the hose 30 is pulled out directly from the rear of the cleaning nozzle 20, and bends downward in a U-shaped turn at the rear and faces forward as its forward-facing part. The other end of the end portion is pulled so as to be connected to the connecting portion 40 existing along the horizontal direction. In this way, the hose 30 is configured to come out from the side of the cleaning nozzle 20, extend to the rear, turn downward in a U-shape, extend forward, and then connect to the connecting portion 40 that exists along the front-rear direction. A plane (YZ plane) perpendicular to the width direction exists.

The flow rate adjustment valve 41 adjusts whether to supply washing water to each hose 30 (each washing nozzle 20 ), and adjusts the flow rate when washing water is supplied. A hose (not shown) connected to a water source other than the hose 30 connected to the washer nozzle 20 is connected to the flow regulating valve 41 .

The flexible rack 50 constitutes one of the power transmission mechanisms that transmit the power of the driving source to the washer nozzle 20 . One end side of the flexible rack 50 is fixed to the washer nozzle 20 . A portion of the flexible rack 50 that is located on the rear side of the portion fixed to the washer nozzle 20 is bent downward. In the present embodiment, an engaging groove 122 capable of engaging the flexible rack 50 is formed in the support base portion 12 of the base member 10 . The engaging groove 122 includes a portion formed in an arc shape with a predetermined curvature. The flexible rack 50 has a plate portion 51 formed in a plate shape and a tooth portion 52 protruding from the plate portion 51 . The width of the tooth portion 52 is smaller than that of the plate-shaped portion 51 , and there are portions where the tooth portion 52 is not formed on both sides of the flexible rack 50 in the width direction. One side of the portion where the tooth portion 52 is not formed is engaged with the engaging groove 122 (see FIG. 6 ). That is, the flexible rack 50 is arranged along the engaging groove 122 . The curvature of the curved portion of the flexible rack 50 matches the curvature of the portion of the engaging groove 122 formed in an arc shape.

The output gear 91 is engaged between a portion fixed to the washer nozzle 20 and a curved portion in the flexible rack 50 . The output gear 91 receives power from a motor 92 as a drive source and rotates. The power transmission mechanism from this motor 92 to the output gear 91 may be any mechanism. As will be described later, the flexible rack 50 is moved by the rotation of the output gear 91 , thereby moving the washer nozzle 20 forward and backward in its longitudinal direction (front-rear direction). The moving flexible rack 50 maintains the shape of its curved portion by the above-mentioned engaging groove 122 .

A portion where the engagement groove 122 is formed in the support base portion 12 of the base member 10 is a wall portion 123 protruding outward in the width direction. In other words, the concave portion recessed inward in the width direction from the tip end of the arc-shaped wall portion 123 is the engaging groove 122 . That is, the engaging groove 122 is formed along the wall portion 123 . On the inner side of the inner peripheral surface of the wall portion 123 , there is formed a thin cylindrical-shaped space with a substantially front side opened. Specifically, the surface on the opposite side to the surface in contact with the plate-like portion 51 of the flexible rack 50 is the surface forming the space. A part of the above-mentioned hose 30 is arranged in this space (hereinafter referred to as hose storage space S). Specifically, the bent portion of the hose 30 is arranged along the wall portion 123 . The height of the wall portion 123 is formed larger than the outer diameter of the hose 30 . That is, the hose 30 arranged in the hose storage space S does not protrude outward in the width direction from the tip of the wall portion 123 .

In this embodiment, the cover member 60 which covers this hose storage space S from the width direction outer side is provided. That is, the cover member 60 covers at least a part of the hose 30 including the bent portion from the outside in the width direction. That is, movement of the hose 30 outward in the width direction is restricted by the cover member 60 . As will be described later in the description of the operation, when the cleaning nozzle 20 moves forward, the hose 30 is displaced so that the curvature of the curved portion becomes large. The cover member 60 is formed in a shape capable of covering at least a part of the hose 30 from the outside in the width direction even when the washing nozzle 20 reaches the washing position and the curvature of the hose 30 is maximized.

Moreover, this cover member 60 is attached so that it may cover the engaging groove 122 formed in the wall part 123 of the support base part 12 from the width direction outer side. That is, since the flexible rack 50 is engaged with the engaging groove 122, the cover member 60 covers at least a part of the flexible rack 50 including the bent portion from the outside in the width direction. That is, like the hose 30 , the movement of the flexible rack 50 outward in the width direction is restricted by the cover member 60 . As will be described later in the description of the operation, when the washer nozzle 20 moves forward, the flexible rack 50 is at least partially engaged with the engaging groove 122 and one end fixed to the washer nozzle 20 moves forward together with the washer nozzle 20 . The cover member 60 is formed in a shape capable of covering at least a part of the flexible rack 50 from the outside in the width direction even when the cleaning nozzle 20 reaches the cleaning position and the flexible rack 50 has moved from the original position.

The human body part washing device 1 having the above configuration operates as follows. When the motor 92 is driven in one direction (forward rotation) with the washer nozzle 20 at the original position, the power thereof is transmitted to the flexible rack 50 via the output gear 91 . One end of the flexible rack 50 fixed to the cleaning nozzle 20 moves in a forward direction. That is, the flexible rack 50 advances together with the cleaning nozzle 20 fixed to the flexible rack 50 . In addition, the other end of the flexible rack 50 moves upward along the arc-shaped portion of the engaging groove 122 .

When the washing nozzle 20 is advanced, the hose 30 connected thereto is tensioned. That is, the hose 30 stretched by the advance of the cleaning nozzle 20 is displaced such that the curvature of the curved portion becomes larger (the radius of curvature becomes smaller). As the cleaning nozzle 20 advances, the curvature of the curved portion of the hose 30 increases, and the curvature of the curved portion becomes maximum when the cleaning nozzle 20 reaches the cleaning position (advancing end position). In this way, even if the curvature changes, the state of the hose 30 along the plane (YZ plane) perpendicular to the width direction is maintained. The cleaning nozzle 20 thus reaches the cleaning position. After the cleaning nozzle 20 reaches the cleaning position, the flow regulating valve 41 is operated, and the cleaning water is delivered to the cleaning nozzle 20 at a predetermined flow rate.

After cleaning, when the motor 92 is driven in the other direction (reversed), its power is transmitted to the flexible rack 50 via the output gear 91 . The other end of the flexible rack 50 fixed to the cleaning nozzle 20 moves in a backward direction. That is, the flexible rack 50 moves backward together with the cleaning nozzle 20 fixed to the flexible rack 50 . In addition, the other end of the flexible rack 50 moves downward along the arc-shaped portion of the engaging groove 122 . When the washing nozzle 20 moves backward, one end of the hose 30 connected thereto moves backward. That is, the hose 30 is displaced such that the curvature of the curved portion becomes smaller (the radius of curvature increases) as the washing nozzle 20 recedes. When the washer nozzle 20 returns to the original position, the curvature of the curved portion of the hose 30 is minimized. This returns the cleaning nozzle 20 to its original position.

According to the human body part washing device 1 according to the present embodiment described above, the following effects are achieved.

The human body part washing device 1 according to the present embodiment has a configuration in which the curvature of the curved portion of the hose 30 is changed while maintaining a state along a plane perpendicular to the width direction as the washing nozzle 20 advances and retreats. That is, the displacement of one end of the hose 30 accompanying the movement of the washer nozzle 20 forward and backward is absorbed by the change of the curvature of the hose 30 itself. Therefore, the winding mechanism of the hose 30 provided in the conventional apparatus becomes unnecessary, and cost reduction is achieved.

Particularly in the present embodiment, the hose 30 connected to each washing nozzle 20 has a flat shape that is flat in the width direction. Therefore, the resistance (reaction force) when changing the curvature of the hose 30 as described above is smaller than when the cylindrical hose 30 is used. That is, it is possible to suppress the energy (the load on the motor 92 as a driving source) when the cleaning nozzle 20 is moved forward and backward. Like the anus cleaning nozzle of this embodiment, when it is necessary to construct a plurality of cleaning water supply flow paths for a certain cleaning nozzle 20, it is only necessary to adopt a method in which the plurality of flow paths are arranged side by side in the width direction, thereby making the whole have a The configuration of the flat hose 30 is sufficient.

In addition, the human body part washing device 1 uses a partly curved flexible rack 50 as a member for transmitting the power of the driving source to the washing nozzle 20 , and is provided with an engaging groove 122 for maintaining the curvature of the flexible rack 50 . In addition, the hose 30 is housed in the hose housing space S inside the wall portion 123 where the engaging groove 122 is formed. It is therefore possible to prevent the hose 30 from interfering with the flexible rack 50 . Specifically, when the hose 30 displaced by the cleaning nozzle 20 that moves forward and backward has a margin, a certain degree of slack occurs in the hose 30 when the cleaning nozzle 20 is in the original position, but the above-mentioned wall is provided. portion 123, so when the hose 30 returns to its original position (when the curvature of the hose 30 becomes the minimum), the hose 30 will not interfere with the flexible rack 50 located outside it. That is, it can be said that the wall portion 123 maintains the curvature of the flexible rack 50 and is formed with the engagement groove 122 for smoothly moving the flexible rack 50 together with the cleaning nozzle 20 , and prevents the hose 30 from coming into contact with the flexible rack. The constitution of rack 50 interference.

Furthermore, in the human body part washing device 1, a cover member 60 covering the hose 30 and the flexible rack 50 is provided. This prevents the hose 30 and the flexible rack 50 from being exposed to the outside. That is, the hose 30 and the flexible rack 50 are pressed from the outside in the width direction by the cover member 60. Therefore, when the cleaning nozzle 20 advances and retreats, the hose 30 and the flexible rack 50 also move along the plane (YZ) perpendicular to the width direction. plane) reliably shifts. For example, it is possible to prevent the flexible rack 50 from being disengaged from the engaging groove 122 when the washing nozzle 20 advances and retreats from the hose 30 being disturbed by the pressure when washing water flows through the hose 30 .

A modified example of the human body part washing device 1 according to one embodiment of the present invention (a human body part washing device 1 a according to the modified example) will be described below. In addition, only the point which differs from the said human body part washing|cleaning apparatus 1 is demonstrated below, About the point which can apply the same structure as the human body part washing|cleaning apparatus 1, description is abbreviate|omitted.

The human body part washing device 1a according to this modified example shown in FIGS. 7 and 8 is different from the aforementioned human body part washing device 1 in the arrangement structure of the flexible rack 50 . One end side of the flexible rack 50 is fixed to the washer nozzle 20 . A part of the flexible rack 50 located behind the portion fixed to the washer nozzle 20 is bent downward, and the other end of the flexible rack 50 is directly fixed to the flexible rack fixing part 124 provided on the base member 10 . . The curved portion of the flexible rack 50 has a shape that surrounds the outside of the curved portion of the hose 30 .

When the washer nozzle 20 at the home position is moved forward, the hose 30 having one end connected to the washer nozzle 20 is displaced so as to increase the curvature of its bent portion. Likewise, the flexible rack 50 whose one end is connected to the washer nozzle 20 is also displaced (displaced from the state shown in FIG. 7 to the state shown in FIG. 8 ) in such a manner as to increase the curvature of its bent portion. When the washing nozzle 20 located at the washing position is retreated, the hose 30 is displaced so as to reduce the curvature of the curved portion. Likewise, the flexible rack 50 is also displaced (displaced from the state shown in FIG. 8 to the state shown in FIG. 7 ) in such a manner that the curvature of its bent portion is reduced.

In this way, when the cleaning nozzle 20 is moved forward and backward, the curved portion of the hose 30 and the curved portion of the flexible rack 50 are displaced together. As a result, the cleaning nozzle 20 that moves forward and backward, together with one end of the hose 30 and one end of the flexible rack 50 connected thereto, move forward and backward together.

The human body part cleaning device 1a involved in this modified example has a configuration in which the curvature of the curved portion of the flexible rack 50 changes when the cleaning nozzle 20 moves forward and backward, that is, the curvature of the flexible rack 50 itself absorbs and cleans A structure in which one end of the flexible rack 50 is displaced in association with the forward and backward movement of the nozzle 20 . Therefore, there is no need for a configuration for maintaining the curved portion of the flexible rack 50 at a constant curvature. In addition, since the flexible rack 50 is not configured to be guided and slid by some other member when the washing nozzle 20 advances and retreats, frictional (sliding) resistance does not occur between the flexible rack 50 and other members. That is, it is possible to reduce the energy loss (the load on the motor 92 as a driving source) due to the generation of this frictional resistance.

As mentioned above, although embodiment of this invention was demonstrated in detail, this invention is not limited to the said embodiment, Various changes are possible in the range which does not deviate from the summary of this invention.
