Description

  The present invention relates to a human body local cleaning device including a cleaning nozzle for cleaning a local part of a human body.

  A cleaning nozzle capable of expanding or changing a cleaning area (cleaning range) by forming a plurality of jet nozzles is known (for example, see Patent Document 1 below).

Japanese Patent Application Laid-Open No. 2001-279979

  The number, shape, arrangement, etc. of the jet nozzles formed in the cleaning nozzle (hereinafter also referred to as the number of jet nozzles, etc.) are the types of equipment (equipment with a variable washing area or changing the washing pressure) Depending on whether it is a device that can be made to operate. That is, it is necessary to prepare a plurality of types of cleaning nozzles in which the number of jets and the like are changed according to the type of apparatus, and the manufacturing cost increases.

  The problem to be solved by the present invention is to provide a human body local cleaning device capable of changing the number of jets and the like at low cost.

  In order to solve the above problems, a local body cleaning apparatus according to the present invention is a part formed separately from a main body part in which a fluid space into which cleaning water flows and the main body part are formed, and jets the cleaning water. And a jet nozzle constituting part fixed to the main body part so as to face the fluid space.

  The said jet outlet structure part is good in it being unremovable with respect to the said main-body part. The term “non-detachable” as used herein refers to a configuration in which a user or the like cannot easily attach or detach the jet outlet component (a configuration that is not assumed to be attached or detached). It does not mean that it is impossible to separate the components.

  The said jet outlet structure part is good to be formed with the metal material.

  It is preferable that another jet port different from the jet port formed in the jet port constituting portion is formed in the main body portion.

  The main body part is formed of a resin material, and the size of the jet port formed in the jet port constituting part may be smaller than the size of the jet port formed in the main body part.

  In the human body local cleaning device according to the present invention, the cleaning nozzle has a main body portion and a jet outlet constituting portion formed separately from the main body portion. That is, since it is possible to change the number of nozzles and the like of the cleaning nozzle by changing only the jet nozzle component, it is possible to suppress the manufacturing cost of the cleaning nozzle.

  When expanding the cleaning area, it is necessary to form a large number of jet nozzles in a wide range. However, simply increasing the number of jet outlets will weaken the momentum of the washing water, so it is necessary to increase the number of jet outlets while reducing the hole diameter of the jet outlet. If the jet nozzle component is formed of a metal material, a small-diameter jet nozzle can be formed with high accuracy.

  When the jet nozzle component is formed of a metal material and the main body is formed of a resin material, the size of the jet nozzle formed in the jet nozzle component is larger than the size of the jet nozzle formed in the main body. It can be easily reduced. In other words, since the jet outlet constituent part is made of a metal material, it is possible to accurately use a laser processing, etching process, etc. to make a jet hole with a small hole diameter (a small diameter jet outlet that cannot be formed in a main body part made of a resin material) It can be formed well.

1 is an external view of a toilet seat device to which a human body local cleaning device according to an embodiment of the present invention is applied. It is an external view of the washing nozzle with which the human body local washing apparatus concerning one embodiment of the present invention is provided. FIG. 3 is a cross-sectional view (a cross-sectional view taken along line AA shown in FIG. 2) in which the cleaning nozzle shown in FIG. 2 is cut in a short direction. It is sectional drawing (BB sectional drawing shown in FIG. 2) which cut | disconnected the washing nozzle shown in FIG. 2 in the longitudinal direction.

  Hereinafter, a human body local cleaning device 1 according to an embodiment of the present invention will be described in detail with reference to the drawings. In the following description, the width direction means a direction along the width direction of the cleaning nozzle 10 (X direction shown in the figure), and the front-rear direction means a direction along the direction in which the cleaning nozzle 10 moves back and forth (Y direction shown in the figure). In other words, the vertical direction means the direction (Z direction shown in the figure) orthogonal to the width direction and the front-rear direction. These directions do not limit the installation direction of the human body local cleaning device 1. For example, the vertical direction may be a direction along the gravity direction, or may be a direction inclined by a certain angle with respect to the gravity direction as in the present embodiment.

  The human body local cleaning device 1 according to the present embodiment is accommodated in an accommodating portion 91 provided behind the toilet seat 90 as shown in FIG. At the time of cleaning, the cleaning nozzle 10 moves forward (positioned at an advanced position described later), and cleaning water is ejected from the ejection port to clean the user's local area. The human body local cleaning device 1 includes a cleaning nozzle 10 for cleaning a local part of the human body.

  The cleaning nozzle 10 in this embodiment shown in FIGS. 2 to 4 includes a nozzle body 20 and a nozzle head 30. The nozzle body 20 is a portion on the proximal end side of the cleaning nozzle 10. The nozzle head 30 is a part connected to the tip (front end) of the nozzle body 20. The nozzle head 30 in the present embodiment can be detachably connected to the nozzle body 20. A space extending in the front-rear direction is formed inside the nozzle body 20, and a part of the hose 40 is located in the space. The hose 40 is connected to a water supply port provided so as to protrude rearward from the rear end surface of the nozzle head 30. In the present embodiment, two ports (first port 311 and second port 312) arranged in the width direction are provided in one nozzle head 30, and the hose 40 is connected to each port.

  The nozzle head 30 has a head main body 31 (corresponding to the main body in the present invention) and a jet outlet constituting part 32. The head main body 31 is made of a synthetic resin material. The head main body 31 in the present embodiment is a combination of an upper main body 31u and a lower main body 31l. The head main body 31 is provided with the first port 311 and the second port 312 described above. Further, a first fluid space 313 connected to a flow path constituted by the first port 311 and a second fluid space 314 connected to a flow path constituted by the second port 312 are formed inside the head main body 31. Yes. The first fluid space 313 and the second fluid space 314 are partitioned. Therefore, the wash water that has flowed into one fluid space does not enter the other fluid space.

  The head main body 31 is formed with a first jet outlet 315 that opens outward. The first jet outlet 315 is connected to the first fluid space 313. That is, the wash water that has flowed into the first fluid space 313 from the first port 311 is ejected from the first ejection port 315. The first fluid space 313 is arranged such that the first outlet 315 is aligned in the front-rear direction with a second outlet 321 (second outlet 321 group) described later (in this embodiment, the first outlet 315 is the second outlet). A bent space (flow path). That is, in this embodiment, one fluid space (flow path) is bent so that the first jet outlet 315 and the second jet outlet 321 are aligned in the front-rear direction.

  At least a part of the upper side of the second fluid space 314 formed in the head main body 31 is open. The jet outlet constituting part 32 is fixed to the head main body part 31 so as to cover the opening. That is, the jet outlet constituting part 32 is fixed to the head main body 31 so that at least a portion where the second jet outlet 321 group is formed faces the second fluid space 314 (see FIGS. 3 and 4). .

  The jet outlet constituting part 32 is formed of a metal material (stainless steel in the present embodiment). Specifically, the metal plate is formed with a plurality of holes serving as the second ejection port 321 group. The jet outlet constituting portion 32 is fixed to the head main body portion 31 by so-called insert molding. That is, the jet nozzle constituting part 32 cannot be attached to and detached from the head main body part 31. The term “non-detachable” as used herein refers to a configuration in which a user or the like cannot easily attach or detach the jet outlet component 32 to the head main body 31 (a configuration that is not premised on being attached or detached). It does not mean that it is impossible to separate the portion 31 and the jet outlet constituting portion 32. Even if the jet nozzle component 32 can be forcibly peeled off from the head main body 31, such a configuration is included in the non-detachable manner.

  As described above, the jet outlet constituting part 32 is fixed to the head main body 31 so as to cover the opening of the second fluid space 314. Therefore, the wash water that has flowed into the second fluid space 314 from the second port 312 is ejected from the second ejection port 321 group. Each second jet port 321 is formed so as to be orthogonal to the planar direction of the flat plate-shaped jet port constituting portion 32. The jet outlet constituting part 32 is fixed so as to be inclined with respect to the upper surface of the head main body part 31. In the present embodiment, since the cleaning nozzle 10 is disposed at a predetermined angle with respect to the direction orthogonal to the direction of gravity (is disposed so that the lower end of the cleaning nozzle 10 is positioned at the lowest position), the cleaning is performed. The direction in which water is ejected (ejection direction) is not orthogonal to the upper surface of the head main body 31. Accordingly, the jet outlet constituting part 32 is fixed so as to be inclined with respect to the upper surface of the head main body part 31 (see FIG. 4). In this embodiment, since the jet nozzle constituting part 32 can be manufactured separately from the head main body part 31, a hole (hole serving as the second jet nozzle 321) perpendicular to the planar direction of the flat jet nozzle constituting part 32 is formed. After the formation, the ejection outlet constituting portion 32 is inclined with respect to the upper surface of the head main body portion 31 so that the ejection direction of the washing water is set to a predetermined direction. That is, after forming a hole orthogonal to the plane direction that is easy to form in the jet outlet constituting portion 32 before being fixed to the head main body portion 31, the jet outlet constituting portion 32 is placed on the upper surface of the head main body portion 31. The washing water is ejected in a direction that is not orthogonal to the upper surface of the head main body 31. That is, according to the present embodiment, it is possible to set the direction in which the washing water is ejected from the second ejection port 321 to a predetermined direction while suppressing the formation of the second ejection port 321 from being difficult. It is. Similarly, the angle of the first jet outlet 315 formed in the head main body 31 is also set as appropriate.

  In this embodiment, the 1st jet nozzle 315 and the 2nd jet nozzle 321 group are located in a line along the front-back direction (longitudinal direction of the washing nozzle 10). Moreover, in this embodiment, the longitudinal direction of the 2nd jet nozzle 321 group is set along the front-back direction. That is, the cleaning area is expanded in the front-rear direction by the second ejection port 321.

  Here, the size (diameter) of each second jet port 321 formed in the jet port constituting portion 32 is smaller than the size (diameter) of the first jet port 315 formed in the head main body portion 31. In the present embodiment, the diameter of the first jet nozzle 315 is about 1.3 mm, whereas the diameter of each second jet nozzle 321 is about 0.3 mm. In the present embodiment, by forming a plurality of such small second outlets 321, the cleaning area is increased while suppressing a decrease in the pressure of the cleaning water to be ejected.

  The reason why the size of the second ejection port 321 can be reduced in this way is that the ejection port constituting portion 32 is formed of a metal material. In the case of a synthetic resin material, it is difficult to form a plurality of such small holes at the time of molding (it is not realistic to mold using a pin of 1 mm or less). It is also difficult to form holes by processing after molding. On the other hand, in the case of a metal material, such a small hole can be accurately formed by laser processing or etching processing. In addition, there is an advantage that the interval between the second ejection ports 321 can be reduced.

  That is, in order to increase the cleaning area, the number of ejection ports must be increased. However, when the entire cleaning nozzle 10 is formed of a synthetic resin material, it is difficult to form a small hole of 1 mm or less. In addition, when the number of holes of 1 mm or more is increased, there is a problem that the cleaning pressure is weakened. On the other hand, in this embodiment, by forming a plurality of small holes of 1 mm or less in the jet nozzle constituting part 32, the cleaning area is increased while suppressing the reduction of the cleaning pressure.

  The cleaning mode using the cleaning nozzle 10 can be set as appropriate. For example, a cleaning mode using only the first jet port 315, a cleaning mode using only the second jet port 321 (group), and a cleaning mode using both the first jet port 315 and the second jet port 321 (group). Any two or more of these may be set in advance, and the user can arbitrarily switch the configuration. Note that the structure for supplying the cleaning water to the cleaning nozzle 10 and the control method thereof may be any configuration, and thus the description thereof is omitted.

  The cleaning nozzle 10 configured as described above can move back and forth between the original position in a state of being accommodated in the accommodating portion and the advance position (cleaning position) where the nozzle head 30 is exposed and local cleaning is performed. is there. Since the driving mechanism of the cleaning nozzle 10 may be any, detailed description thereof is omitted. A plurality of positions may be set as the advance position. In addition, the cleaning nozzle 10 may be configured to move forward and backward with respect to the base (portion fixed to the toilet bowl) of the apparatus, or one or a plurality of other members configured to be slidable with respect to the base. On the other hand, the cleaning nozzle 10 may be configured to move forward and backward (so-called multistage nozzle).

  In the human body local cleaning device 1 according to the present embodiment described above, the cleaning nozzle 10 includes the head main body 31 and the jet outlet constituting part 32 formed separately from the head main body 31. That is, since it is possible to change the number of jet nozzles and the like of the cleaning nozzle 10 by changing only the jet nozzle constituting portion 32, the manufacturing cost of the cleaning nozzle 10 can be suppressed.

  As mentioned above, although embodiment of this invention was described in detail, this invention is not limited to the said embodiment at all, A various change is possible in the range which does not deviate from the summary of this invention. For example, the following modifications can be considered.

  The cleaning nozzle 10 in the embodiment described above includes the nozzle main body 20 and the nozzle head 30, and the nozzle head 30 has been described as having the head main body portion 31 and the jet outlet constituting portion 32. These portions may be integrally formed (the nozzle head 30 may not be detachable from the nozzle body 20). That is, it is good also as a structure for parts other than the jet nozzle structure part 32 in the washing nozzle 10 equivalent to the main-body part in this invention. In this case, it is good also as a structure by which the hose 40 was connected to the rear end of the washing nozzle 10, and the flow path for conveying washing water to a jet nozzle was formed in the nozzle.
