Description

  The present invention relates to a water soap dispenser disposed in a toilet or a washroom provided in a public facility such as a station, a hotel, a department store, or a restaurant.

  In the toilets and washrooms provided in public facilities such as stations, hotels, restaurants, etc., a soap dispenser containing soap for hand washing is disposed. As a conventional water soap discharge device, for example, there is a “water soap supply tap” described in Patent Document 1. This “water soap supply plug” has a structure including a main body (plug body) fixed to a wall surface and the like, and a water soap tank disposed above the main body. When the user presses a push button protruding from the front of the main body, the valve element disposed in the flow path formed in the main body moves to open the flow path, and enters the soap tank. The stored soap and water moves downward through the flow path, and flows out from an outlet formed on the lower surface of the main body.

Japanese Patent Laid-Open No. 7-222893

  In the water soap discharge device (water soap supply tap) described in Patent Document 1, the male screw portion provided on the outer periphery of the lower end opening of the water soap tank is replaced with the female screw portion provided on the inner periphery of the upper surface opening of the main body. The water soap tank is fixed to the main body by direct screwing. Accordingly, when the water soap tank is rotated, the threaded portion is easily loosened to form a gap, or the water soap tank is detached from the main body. For this reason, the water soap flows out from the gap between the screwed portions or the opening of the water soap tank that has been removed, and waste of the water soap is generated. Moreover, the water soap tank removed from the main body part may be carried away by mischief or the like.

  The problem to be solved by the present invention is a water soap that does not loosen the connecting portion between the tank and the main body even if a rotational force is applied to the tank due to mischief or error, or the tank does not come off from the main body. It is to provide a discharge device.

The water soap dispenser of the present invention is
A tank for storing water soap;
A discharge port that discharges soapy water supplied from the tank; and a valve mechanism that stops discharge of soapy water from the discharge port; a main body that can be attached to a fixed object such as a wall;
In a water soap dispenser comprising a coupling mechanism for detachably attaching the tank to the tank introduction part of the main body part,
As the connection mechanism,
A cylindrical connecting member rotatably mounted on the outer periphery of a cylindrical opening projecting from the tank;
A stopper member for holding the connecting member so as not to come out of the cylindrical opening;
A female screw part provided on the inner periphery of the tank introduction part of the main body part for screwing a male screw part provided on the outer periphery of the connecting member;
And a tool engaging portion provided in the connecting member for engaging the tool.

  With such a configuration, the cylindrical opening projecting from the tank is connected to the tank introduction portion of the main body, and the male screw portion on the outer periphery of the connecting member attached to the outer periphery of the cylindrical opening is introduced to the tank. The connecting member is fixed to the tank introduction portion by screwing into a female screw portion on the inner periphery of the portion, engaging a tool such as a spanner with a tool engaging portion provided on the connecting member, and tightening the connecting member. Since the connecting member is attached to the outer periphery of the cylindrical opening of the tank so as not to be detached, the connecting member is fixed to the tank introducing part, so that the cylindrical opening is also fixed to the tank introducing part so as not to be detached. As a result, the tank is connected in communication with the tank introduction portion of the main body.

  Since the connecting member is rotatably mounted on the outer periphery of the cylindrical opening of the tank, when a rotational force is applied to the tank, only the tank rotates and the connecting member does not rotate. Therefore, even if a rotational force is applied to the tank due to mischief or error, the connecting portion between the tank and the main body does not loosen or the tank does not come off from the main body.

  Here, the tool engaging portion can be provided on the outer periphery of the enlarged diameter portion formed on the connecting member and having an outer diameter larger than the opening end of the tank introduction portion. With such a configuration, the tool engaging portion is located on the outer periphery of the enlarged diameter portion having an outer diameter larger than the opening end of the tank introduction portion, and the tool can be easily engaged with the tool engaging portion. Therefore, workability when tightening or loosening the connecting member is improved. Further, when the connecting member is tightened, further tightening becomes impossible when the enlarged diameter portion comes into contact with the opening end of the tank introduction portion, so that the completion of tightening can be easily grasped.

  On the other hand, the tool engaging portion may be provided on the bottom surface of a circumferential groove that is recessed in the outer periphery of the connecting member. With such a configuration, the tool that can be engaged with the tool engaging portion is limited to a size (thickness) that can be inserted into the circumferential groove. For this reason, if the width of the circumferential groove is set to a size in which a general-purpose tool cannot be inserted, it is possible to prevent mischief such as loosening the connecting member using a generally-available general-purpose tool.

  In this case, as the tool engaging portion, at least a pair of plane portions that are parallel to each other across the rotation axis of the connecting member can be provided on the outer periphery of the connecting member. With such a configuration, it is possible to rotate a connecting member by engaging a tool such as a spanner with a pair of flat portions, so that a tool engaging portion having a relatively simple shape can be reliably used. It is possible to obtain an engaged state with a simple tool.

  On the other hand, in order to connect the tank to the main body portion in a non-rotatable manner, a fitting means that can be engaged with and disengaged from each other can be provided between the stopper member and the tank introduction portion. With such a configuration, it is impossible to rotate the tank itself, so even if a rotational force is applied to the tank due to errors or mischief, the connection between the tank and the main body is loosened, or the tank is It will not come off the part.

  In this case, as the fitting means, it is desirable to provide a spline structure that can be fitted to each other on the outer periphery of the stopper member and the inner periphery of the tank introduction portion. With such a configuration, a reliable tank rotation prevention effect can be obtained without impeding workability when the tank is connected to or detached from the main body.

  According to the present invention, there is provided a water soap dispenser in which a connecting portion between a tank and a main body does not loosen or the tank does not come off from the main body even if a rotational force is applied to the tank due to mischief or error. Can do.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The main body 19 is fixed to the wall surface W through a fixing tool 22 having a protruding bar 22a and a cover 24 covering the fixing tool 22. The fixing tool 22 is fixed to the wall surface W by three screws 21, and a cover 24 is attached so as to cover the front portion including the proximal end portion of the protruding rod 22a. The main body 19 is attached in such a manner that the protruding collar 22a of the fixture 22 is inserted into a locking hole 19a provided in an open state on the back surface thereof, and upward from the lower surface of the main body 19. The screw 23 is inserted and fixed to the fixture 22 by being screwed into a female screw hole 22b provided in the protruding rod 22a. When the protruding collar 22a is inserted into the locking hole 19a of the main body 19, the protrusion 19c provided in the locking hole 19a and the flat surface 22c provided at the tip of the protruding collar 22a are in surface contact. By doing so, the positions of both are uniquely determined.

  A valve mechanism 18 for stopping the discharge of water soap from the discharge port 16 includes a valve seat 25 arranged coaxially with the discharge port 16, and a valve body 26a arranged on the upper surface side of the valve seat 25 so as to be movable up and down. An operating rod 26, a spring 27 that urges the entire operating rod 26 including the valve body 26a toward the valve seat 25, and a hat-shaped fixture 28 that presses and fixes the spring 27 toward the valve body 26a are provided. .

  A connecting mechanism 20 for detachably attaching the tank 14 to the tank introducing portion 15 of the main body portion 19 is a short cylindrical connecting portion rotatably attached to the outer periphery of a cylindrical opening portion 14a projecting from the lower surface portion of the tank 14. The member 29, a female screw portion 15a provided on the inner periphery of the tank introduction portion 15 of the main body 19 for screwing the male screw portion 29a provided on the outer periphery of the connecting member 29, and the connecting member 29 are connected to the cylindrical opening 14a. And a stopper member 30 that is attached to the outer periphery so as not to be detached. And the enlarged diameter part 29c which has an outer diameter larger than the opening end of the tank introduction part 15 is formed in the outer periphery of the upper end side of the connection member 29, and tools, such as a spanner, are engaged with the outer periphery of the enlarged diameter part 29c. A plurality of plane portions 29b are provided as tool engaging portions for this purpose.

  Since the inner diameter of the connecting member 29 is larger than the outer diameter of the cylindrical opening 14a of the tank 14, as shown in FIG. 5, after the connecting member 29 is fitted on the outer periphery of the cylindrical opening 14a, the connecting member 29 is cylindrical. If the short cylindrical stopper member 30 is attached to the end face side of the opening 14a and is fixed with an adhesive or the like, the connecting member 29 is mounted on the outer periphery of the cylindrical opening 14a in a rotatable and non-detachable manner. A spline 30 a is formed on the outer periphery of the stopper member 30, and the spline 30 a can be engaged with a spline 15 b provided near the bottom surface of the inner periphery of the tank introduction portion 15.

  An opening 14b is provided on the upper surface of the tank 14, a lid 14c that opens and closes the opening 14b is attached to be rotatable about a support shaft 14d, and a vent hole 14e is provided in a part of the lid 14c. Yes. When the lid 14c is rotated about the support shaft 14d, the opening 14b on the upper surface of the tank 14 is exposed or closed, so that water soap can be supplied into the tank 14 and the like.

  In the water soap dispenser 10 of the present embodiment, the cylindrical opening 14a projecting from the lower surface of the tank 14 is inserted into the main body 19 in a state where the valve mechanism 18 and the ring-shaped sealing material 31 are inserted. Connect to tank inlet 15. Then, the spline 30a on the outer periphery of the stopper member 30 is engaged with the spline 15b on the inner periphery of the tank introduction portion 15, and the male screw portion 29a on the outer periphery of the connecting member 29 attached to the outer periphery of the cylindrical opening portion 14a is introduced into the tank. Screwed into the female screw portion 15a on the inner periphery of the portion 15. Then, if the thin plate-shaped dedicated tool T shown in FIG. 8 is engaged with the flat surface portion 29 b for tool engagement provided in the connecting member 29 and the connecting member 29 is tightened, the connecting member 29 becomes the tank introducing portion 15. Fixed to.

  In this state, since the connecting member 29 is attached to the outer periphery of the cylindrical opening 14 a of the tank 14 by the stopper member 30 so as not to be detached, when the connecting member 29 is fixed to the tank introducing portion 15, the cylindrical opening The portion 14 a is fixed to the tank introduction portion 15 so as not to be detached, whereby the tank 14 is connected in communication with the tank introduction portion 15 of the main body portion 19.

  At this time, the connecting member 29 is rotatably mounted on the outer periphery of the cylindrical opening 14a of the tank 14, but the stopper member 30 fixed to the lower end of the cylindrical opening 14a is connected to the tank by the splines 30a and 15b. It is engaged with the inner periphery of the introduction portion 15 in a non-rotatable manner. Therefore, even if a rotational force is applied to the tank 14, the tank 14 does not rotate. For this reason, even if a rotational force is applied to the tank 14 due to mischief or error, the connecting portion between the tank 14 and the main body portion 19 does not loosen or the tank 14 does not come off the main body portion 19. In addition, although the material of the tank 14 and the cover body 14c is not limited, since these are formed with stainless steel in this embodiment, they are hard to be damaged or rusted, and are excellent in durability.

  Further, as shown in FIG. 5, two pairs of plane portions 29b that are parallel to each other across the rotation axis C of the connecting member 29 are provided on the outer periphery of the enlarged diameter portion 29c of the connecting member 29 as a tool engaging portion. Yes. Therefore, if the thin plate-like dedicated tool T shown in FIG. 8 is engaged with the pair of flat portions 29b, the connecting member 29 can be rotated, and while the tool engaging portion has a relatively simple shape, The dedicated tool T can be reliably engaged.

  Further, the enlarged diameter portion 29 c having two pairs of flat portions 29 b on the outer periphery is larger in diameter than the inner diameter of the opening end of the tank introduction portion 15. Therefore, when the connecting member 29 is rotated and tightened, the lower surface of the enlarged diameter portion 29c comes into contact with the opening end of the tank introducing portion 15, so that the connecting member 29 is not excessively tightened. For this reason, the opening end of the cylindrical opening portion 14a is excessively pressed against the valve seat 25, the valve seat 25 is damaged or the valve seat 25 is deformed, and the sealing performance is impaired, so that Can be eliminated.

  The water soap dispenser 10 is used in the same manner as the conventional apparatus, and as shown in FIG. 3, when the operating rod 26 protruding from the lower surface of the main body 19 is pushed upward, the valve element 26a is separated from the valve seat 25. Therefore, the soap that is accommodated inside the cylindrical opening 14a passes through the gap between the operation rod 26 and the inner periphery of the discharge port 16 and is discharged downward. When the pushing force on the operating rod 26 is released, the operating rod 26 is lowered by the restoring force of the spring 27 and the valve body 26a is pressed against the valve seat 25 to close the gap, so that the discharge of soap is stopped. .

  Next, another embodiment of the present invention will be described with reference to FIGS. 6 and 7 are partially cutaway sectional views showing a water soap dispenser according to another embodiment of the present invention. 6 and 7, the parts denoted by the same reference numerals as those shown in FIGS. 1 to 5 are parts that exhibit the same functions and effects as the constituent parts of the water soap dispenser 10 described above. The description is omitted.

  In the soap and water discharging apparatus 50 shown in FIG. 6, a circumferential groove 39 d is provided along the outer periphery of the connecting member 39 as a tool engaging portion of the connecting member 39 having the same function as the connecting member 29 of the soap and water discharging apparatus 10. A flat portion 39b similar to the flat portion 29b shown in FIG. 5 is provided on the bottom surface of the circumferential groove 39d.

  With such a configuration, the tool that can be engaged with the flat portion 39b is limited to a size (thickness) that can be inserted into the circumferential groove 39d. Therefore, if the width of the circumferential groove 39d is a size that a general-purpose tool cannot be inserted and only a special tool T having a small thickness can be inserted as shown in FIG. It is possible to prevent mischief such as loosening the connecting member 39 using a tool.

  Further, when the connecting member 39 is tightened using the dedicated tool T, the gap between the upper inner surface of the circumferential groove 39d and the upper edge 15c of the tank introducing portion 15 is narrowed. It is held in the gap and cannot be tightened. Therefore, if the setting is made so that a predetermined tightening torque can be obtained in a state where the tightening is impossible, the connecting member 39 can be always tightened with an appropriate tightening torque, so that excessive tightening and insufficient tightening do not occur. Other structures and functions are the same as those of the water soap dispenser 10 described above.

  In FIG. 6, since the outer peripheral portion of the connecting member 39 near the tank 14 is provided with the male screw portion 39 a and the enlarged diameter portion 39 c having an outer diameter larger than the opening end of the tank introduction portion 15, the circumferential groove 39 d It is located at the boundary between the male screw portion 39a and the enlarged diameter portion 39c. Accordingly, when the connecting tool 39 is tightened by engaging the dedicated tool T shown in FIG. 8 with the flat surface portion 39b of the bottom surface of the circumferential groove 39d, the lower surface of the enlarged diameter portion 39c positioned above the circumferential groove 39d and the tank introduction The gap with the upper edge portion 15c of the portion 15 is narrowed. Finally, the dedicated tool T is held in this gap and strongly contacts the lower surface of the enlarged diameter portion 39c, so that the connecting member 39 cannot be tightened without damaging the circumferential groove 39d.

  Next, in the soap and water discharging apparatus 60 shown in FIG. 7, the enlarged diameter portion 39e having an outer diameter larger than the outer diameter of the upper edge portion 15c of the tank introduction portion 15 on the outer periphery of the region close to the tank 14 of the connecting member 39. In addition to the flat surface portion 39b on the bottom surface of the circumferential groove 39d, a plurality of flat surface portions 39b ′ that are parallel to each other are provided on the outer periphery of the enlarged diameter portion 39e. Therefore, if a tool such as a spanner is engaged with these flat portions 39b ', the connecting member 39 can be rotated without using the thin dedicated tool T.
