Description

  The present invention relates to a lid of a bathroom installation container used in a bathroom, such as a detergent tank of a bathtub cleaning device, and a bathroom installation container provided with the lid.

The present applicant has previously proposed a detergent tank described in Patent Document 1 as an example of a bathroom installation container.
The detergent tank described in the document is shown in FIG. 5 of the present application. The detergent tank Ae includes a detergent tank main body 1e (container main body) having a mouth and neck 10e, and a lid 2e attached to the mouth and neck 10e via an auxiliary member 3e.

  Such a detergent tank Ae is used, for example, in a state in which a lower portion in the detergent tank Ae is branched and connected to a hot water supply path of a bathtub cleaning device via an appropriate piping member. The hot water supply path is a path for supplying a detergent or hot water to the bathtub cleaning nozzle, by allowing the detergent to flow from the detergent tank Ae to the hot water supply path using the Venturi effect and mixing the hot water with the hot water. This mixed water (detergent water) can be ejected from the washing nozzle toward the bathtub. When the detergent flows out of the detergent tank Ae toward the hot water supply path, a negative pressure is generated in the detergent tank Ae. Therefore, in order to make the outflow of the detergent from the detergent tank Ae smooth, the detergent tank Ae needs to have air permeability with the outside.

Therefore, in Patent Literature 1, ventilation means is provided on the lid 2e. The lid 2e has a configuration in which a downwardly projecting cylindrical wall portion 22e protrudes from the back surface of the lid main body portion 20e, and a downwardly facing peripheral wall portion 29e is continuously provided on the outer peripheral edge. The cylindrical wall portion 22e is externally fitted and screwed to the auxiliary member 3e. As the ventilation means, a cylindrical groove-shaped first notch 9a formed on the back surface of the lid main body 20e and an upper part communicating with the first notch 9a are provided. A configuration is employed in which a concave notch-shaped second notch 9b extending in the vertical direction on the inner peripheral surface (screw portion) of 22e is combined. The second notch 9b has a lower end opening 90 having a downward opening shape.
According to such a configuration, since the air permeability can be provided through the first and second notches 9a and 9b, the outflow of the detergent from the detergent tank Ae can be smoothly performed. The downward facing peripheral wall portion 29e of the lid body portion 20e serves to suppress, for example, shower water used in a bathroom from directly splashing on the lower end opening portion 90 of the second cutout portion 9b.

  However, there is still room for improvement in the prior art as described below.

That is, the first notch 9a is a concave groove provided on the back surface of the lid main body 20e, and the second notch 9b is provided on the inner periphery of the cylindrical wall 22e of the lid 2e. It is difficult to form these with a large opening area because of the concave groove shape. For this reason, when a negative pressure is generated in the detergent tank Ae, the flow velocity of the air passing through the first and second notches 9a and 9b increases. As a result, if water such as residual shower water is present near the lower end opening 90 of the second notch 9b, this water is drawn into the second notch 9b by the airflow having a high flow velocity. It may flow into the detergent tank Ae. The occurrence of such a phenomenon is not preferable because the water is mixed in the detergent in the detergent tank Ae.
Further, in the conventional technique, the downward facing peripheral wall 29e of the lid body 20e surrounds the entire circumference of the cylindrical wall 22e, and when water enters inside the peripheral wall 29e, the water is Due to the surface tension, it is difficult to discharge to the outside of the peripheral wall portion 29e. Therefore, much of the water that has entered the inside of the peripheral wall portion 29e is sucked into the second cutout portion 9b, and there is a possibility that the phenomenon that water flows into the detergent tank Ae is more likely to occur.

JP-A-10-234599

  The present invention has been conceived under the circumstances described above, and it is possible to appropriately prevent or suppress the intrusion of unjustified water into the inside while appropriately securing the air permeability. An object of the present invention is to provide a lid for a bathroom installation container and a bathroom installation container provided with the lid.

  In order to solve the above problems, the present invention takes the following technical measures.

  The lid of the bathroom-installed container provided by the first aspect of the present invention is provided with a downwardly convex cylindrical wall portion on the back surface, and the cylindrical wall portion is connected to the mouth and neck portion of the container body portion or the mouth portion. A lid main body that can be attached to the container main body in a state where the lid main body is fitted to the cylindrical auxiliary member attached to the neck, and the container main body in a state where the lid main body is attached to the container main body. A ventilating means for ventilating the inside of the part with the outside, comprising: a lid of a bathroom installation container, wherein at least one of the at least one ventilating means is provided through the cylindrical wall in a thickness direction thereof. The air conditioner further includes an outer wall portion that has a ventilation hole, protrudes downward from the lid main body, and faces the ventilation hole at a position spaced apart from the outside of the cylindrical wall portion.

According to such a configuration, the following effects can be obtained, as well as the bathroom installation container can be provided with air permeability by using the ventilation holes.
First, the ventilation hole is provided so as to penetrate the cylindrical wall portion of the lid in the thickness direction, and can have a relatively large area. Therefore, in addition to being able to stabilize the intake air from the outside into the bathroom installation container when the inside of the bathroom installation container becomes a negative pressure, it is also possible to reduce the flow velocity when air passes through the ventilation hole. . As a result, if water such as residual shower water is present near the ventilation holes, this phenomenon is properly prevented from being drawn into the ventilation holes due to the high-speed airflow and flowing into the bathroom installation container. Or can be suppressed.
Secondly, the vent can be covered with the outer wall portion, and even when water such as shower water scatters directly toward the lid, this water is directly applied to the position of the vent. It is possible to appropriately prevent such a situation that the user gets into the inside by hanging. Therefore, even when the vent is provided with a relatively large area, the intrusion of water into the bathroom installation container through the vent is appropriately prevented or suppressed.

  In the present invention, preferably, the outer wall portion is formed as a wall portion that is discontinuous in a circumferential direction of the lid main body portion.

  According to such a configuration, unlike the case where the outer wall is formed in a cylindrical shape that is continuous in the circumferential direction of the lid main body, the water that has entered the inside of the outer wall is caused by the surface tension of the outer wall. It can be prevented from being easily discharged to the outside of the part. Therefore, it is possible to make it more difficult for water to enter the ventilation hole existing inside the outer wall portion, and further to enter the bathroom installation container.

  In the present invention, preferably, the width of the gap between the outer wall portion and the cylindrical wall portion is formed so as to become narrower as the portion approaches the ventilation hole.

  According to such a configuration, as understood from an embodiment described later with reference to FIG. 4, water (steam) such as shower water is supplied to a gap between the outer wall portion and the cylindrical wall portion. (Including a lot of air, etc.), these flows have a higher flow velocity as they approach the ventilation holes. In this case, the effect of applying a negative pressure to the ventilation hole by the Venturi effect and allowing air to flow out from the ventilation hole toward the gap can be expected. As a result, it is possible to prevent water from entering the ventilation hole from the gap, and it is possible to more reliably prevent or suppress the unauthorized entry of water into the bathroom installation container.

  In the present invention, preferably, in plan view, the cylindrical wall portion is cylindrical, and a surface of the outer wall portion facing the cylindrical wall portion is an outer peripheral surface of the cylindrical wall portion. Is a planar shape extending in a tangential direction of.

  According to such a configuration, a configuration in which the width of the gap between the outer wall portion and the cylindrical wall portion decreases as the portion approaches the ventilation hole can be appropriately realized with a simple configuration. In addition, the gap formed by the above configuration has the narrowest width in the vicinity of the ventilation hole at the center of the gap, and has a wide shape at both ends, so that water that has entered the gap from one end thereof has a width equal to the width of the center. After passing through the narrow portion, the portion easily reaches the other end through the portion where the width gradually increases. Therefore, an effect of making it difficult for water to remain in the gap can be obtained.

  In the present invention, preferably, a plurality of outer walls protruding downward from an outer peripheral edge of the lid body so as to be located outside the cylindrical wall, and arranged at intervals in a circumferential direction of the lid body. And at least one of the plurality of outer wall portions is the outer wall portion facing the ventilation hole.

  According to such a configuration, when the lid is gripped by hand, it becomes easy to hook the fingers on the plurality of outer wall portions. Therefore, the hand becomes less slippery, and usability can be improved.

  In the present invention, preferably, in the cylindrical wall portion, an annular concave portion is provided on an inner peripheral surface at a position below the vent hole, and is provided on an outer peripheral surface of the mouth and neck portion or the auxiliary member. There is further provided an annular convex or concave seal portion capable of fitting with the convex portion.

  According to such a configuration, even if water enters the lower part of the gap formed between the mouth and neck or the auxiliary member and the cylindrical wall, even if water enters, the position of the seal portion is changed. Ascending to the position of the vent hole is appropriately prevented by the presence of the seal portion. Therefore, it is possible to more reliably prevent water from entering the bathroom-installed container through the ventilation hole.

  The bathroom-mounted container provided by the second aspect of the present invention is characterized by including the bathroom-installed container lid provided by the first aspect of the present invention.

  According to such a configuration, an effect similar to that described for the lid of the bathroom installation container provided by the first aspect of the present invention can be obtained.

  Other features and advantages of the present invention will become more apparent from the following description of embodiments of the invention with reference to the accompanying drawings.

It is an outline perspective view of the bathroom installation container concerning the present invention. It is principal part sectional drawing of the bathroom installation container shown in FIG. 1, and its principal part expanded sectional view. (A) is a perspective view of the lid of the bathroom installation container shown in FIG. 1, (b) is a IIIb-IIIb cross-sectional view of (a), (c) is a IIIc-IIIc cross-section of (a) FIG. (A) is a perspective view of the back side of the lid of the bathroom installation container shown in FIG. 1, and (b) is a bottom view of the lid shown in (a) and an enlarged view of a main part thereof. It is principal part sectional drawing which shows an example of a prior art.

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

  The bathroom installation container A shown in FIGS. 1 and 2 is a detergent tank for storing a liquid detergent for bathroom cleaning therein and supplying the detergent to a predetermined hot water supply path of a bathroom cleaning device (not shown). The bathroom-installed container A includes a container body 1, a lid 2, an auxiliary member 3, and an additional lid 5. These materials are all made of resin, but are not limited thereto. Note that the bathroom installation container A is also provided with a packing 4 made of rubber or resin.

The additional lid 5 is attached to the container main body 1 in a screwing manner so as to seal the opening 18 provided in the container main body 1. A sensor (not shown) for detecting the liquid level of the detergent is inserted. The additional lid 5 does not have air permeability and does not correspond to the lid of the bathroom-installed container of the present invention. (However, the present invention is applied to the additional lid 5 for a sensor to have air permeability. A configuration is also possible.)
In FIG. 1, reference numeral 19 denotes a detergent outflow pipe, and the detergent is supplied to a desired position via the piping member 6 connected to the outflow pipe 19.

  The container main body 1 is formed in a shape and a size suitable for accommodating a detergent. An opening 10a for introducing a detergent is formed at an upper end of the container main body 1, and a mouth and neck having a screw portion 10b on an outer peripheral surface. The part 10 is formed integrally. As will be described later, the lid 2 is attached to the mouth and neck 10 via the auxiliary member 3.

  The auxiliary member 3 has a substantially cylindrical shape with a different diameter, and an outer peripheral step portion 30 having an outer diameter larger than other portions is formed on an upper outer peripheral surface of the auxiliary member 3, and is formed on an upper inner peripheral surface. Is formed with an inner peripheral side step portion 31 having an inner diameter smaller than other portions. On the inner peripheral surface of the auxiliary member 3, a screw portion 32 is formed below the inner peripheral side step portion 31. The auxiliary member 3 is fitted around the mouth and neck portion 10, and the screw portions 10b and 32 are screwed together.

  As shown in FIGS. 3 and 4, the lid 2 includes a lid body 20 having a substantially disk-shaped top plate 21 and a downwardly projecting cylindrical wall 22 provided on the back surface thereof. And a plurality of outer wall portions 23 protruding downward from the outer peripheral edge of the outer peripheral portion, which are integrally formed. A plurality of ventilation holes 24 are provided in the cylindrical wall portion 22.

As shown in FIG. 2, the cylindrical wall portion 22 can be fitted on the outer peripheral surface of the outer peripheral side step portion 30 of the auxiliary member 3. On the inner peripheral surface of the cylindrical wall portion 22, there is provided an annular convex seal portion 25 which can be fitted (engaged) into an annular concave portion 33 formed on the outer peripheral surface of the outer peripheral side step portion 30. I have. The fitting of the seal portion 25 and the concave portion 33 achieves a waterproof seal. Preferably, the seal portion 25 is provided below the vent hole 24, and even if water enters the gap between the lower end portion of the cylindrical wall portion 22 and the outer peripheral surface of the outer peripheral side step portion 30. The seal portion 25 prevents water from entering the bathroom installation container A.
In the present invention, contrary to the present embodiment, an annular convex portion may be formed on the outer peripheral side step portion 30 and the seal portion 25 may be formed into an annular concave shape that can be fitted to the convex portion. .

The ventilation hole 24 is provided so as to penetrate the cylindrical wall portion 22 in the thickness direction thereof, and has, for example, a substantially oval or rectangular shape having an appropriate length in the circumferential direction of the cylindrical wall portion 22. However, other forms such as a round hole may be used. In the present embodiment, the ventilation holes 24 are provided at a total of two locations facing each other with the center of the cylindrical wall portion 22 interposed therebetween. As shown in the main part enlarged sectional view of FIG. 2, the ventilation hole 24 is provided near the upper base of the cylindrical wall portion 22 so as not to be blocked by the auxiliary member 3. The outer peripheral edge is provided with a tapered portion 34 that is separated from the location where the vent hole 24 is formed.

  As shown in FIG. 4, the plurality of outer wall portions 23 are spaced apart from the cylindrical wall portion 22 to the outside (radially outward), and are spaced apart from each other in the circumferential direction of the lid main body portion 20. It is a non-cylindrical wall that is arranged side by side and is discontinuous in the circumferential direction. Of the plurality of outer wall portions 23, two outer wall portions 23 (23A) face the air holes 24. An inner side surface 23a of each outer wall portion 23 is a flat surface extending in a tangential direction of an outer peripheral surface of the cylindrical wall portion 22. 4B, the width La of the gap C between the cylindrical wall portion 22 and the inner side surface 23a of the outer wall portion 23 approaches the ventilation hole 24. As shown in FIG. It gradually becomes narrower. This configuration causes an effect that water hardly enters the ventilation hole 24 due to the Venturi effect, as described later.

  Next, an example of use and operation of the above-described bathroom installation container A will be described.

  As shown in FIG. 2, the bathroom installation container A is attached such that the container main body 1 is located below the bathtub flange 7, for example. Specifically, a hole 70 is provided in the bathtub flange 7, and the auxiliary member 3 is inserted into the hole 70 so that the upper outer peripheral step 30 is locked to the upper surface of the bathtub flange 7. ing. A packing 4 is interposed between the lower surface side of the bathtub flange 7 and the container body 1, and the bathtub flange 7 is sandwiched by both the packing 4 and the outer peripheral side step portion 30. The piping member 6 connected to the outflow pipe 19 shown in FIG. 1 is branched and connected to a hot water supply path of a bathroom cleaning device (not shown) via a venturi section, and the bathroom is operated by a negative pressure generated in the venturi section. The detergent in the installation container A flows into the hot water supply channel, and the detergent mixed with the hot water is jetted from the cleaning nozzle toward the bathtub.

  When the detergent in the bathroom installation container A flows out of the outflow pipe 19, a negative pressure is generated in the bathroom installation container A, and external air flows into the bathroom installation container A through the ventilation hole 24. Here, the ventilation hole 24 is provided to penetrate the cylindrical wall portion 22 of the lid 2 and can have a relatively large opening area. Therefore, the ventilation through the ventilation holes 24 can be stabilized. In addition, if the opening area of the ventilation hole 24 is increased, the flow velocity of the air flow passing through the ventilation hole 24 can be reduced. This also prevents or suppresses water from entering the ventilation holes 24.

  An outer wall portion 23 is located outside the vent hole 24. Even when water such as shower water scatters toward the lid 2, the water does not directly fall on the vent hole 24. This is prevented by the part 23. Therefore, it becomes more difficult for water to enter the ventilation hole 24, and even if the ventilation hole 24 is provided with a relatively large area, the water enters the bathroom installation container A via the ventilation hole 24 unjustly. Can be appropriately prevented or suppressed.

  Since the plurality of outer wall portions 23 are separated from each other in the circumferential direction, when water enters the inside of the plurality of outer wall portions 23, it is possible to easily drain the water to the outside. That is, unlike the present embodiment, if the outer wall portion 23 has a cylindrical shape that is continuous in the circumferential direction, the water that has entered the inside of the outer wall portion 23 may be externally caused due to surface tension. And it is difficult for water to remain. In this case, there is a high possibility that the residual water enters the ventilation holes 24. On the other hand, according to the configuration of the present embodiment, an effect of making such a phenomenon unlikely to occur can be obtained.

In the main part enlarged view of FIG. 4B, for example, a water flow such as shower water flows into a gap C between the outer wall portion 23 and the cylindrical wall portion 22, as shown by an arrow Na, on one end side thereof. When approaching from above, the width La of the gap C becomes narrower as approaching the vent hole 24, so that the water flow becomes faster. Then, an action of flowing out air from the vent hole 24 to the gap C side is obtained by the Venturi effect. Therefore, the water flow can be prevented from entering the ventilation holes 24 from the gap C. When the water flow passes near the ventilation hole 24, the width La of the gap C gradually increases. Therefore, the water flow smoothly flows through the gap C and easily flows out from the other end of the gap C to the outside. Therefore, an effect of making it difficult for water to remain in the gap C is also obtained.

  Water sealing is achieved by fitting the seal portion 25 and the annular concave portion 33, and water is injected into a minute gap between the lower end portion of the cylindrical wall portion 22 and the outer peripheral surface of the outer peripheral step portion 30 of the auxiliary member 3. Even if the water enters, the water is appropriately prevented from entering the interior of the bathroom-installed container A beyond the above-mentioned water-stop seal.

  At the time of opening and closing the lid 2, the user grips the lid 2 with his / her hand. In this case, it suffices to hook a finger on the plurality of outer wall portions 23. Since the plurality of outer wall portions 23 are arranged apart from each other, such hooking of the finger can be performed easily and naturally, and the usability is good.

  The present invention is not limited to the contents of the above-described embodiment. The specific configuration of the lid of the bathroom installation container and each part of the bathroom installation container according to the present invention can be variously modified within the range intended by the present invention.

  In the above-described embodiment, a total of two ventilation holes are provided in the cylindrical wall portion of the lid, but the number of ventilation holes is not particularly limited as long as at least one ventilation hole is provided. Further, as described above, the shape of the ventilation hole is not limited, and its specific size does not matter.

  The outer wall portion of the lid in the present invention is originally provided so as to face the air hole, and prevents or suppresses the water from being applied to the air hole. However, as in the above-described embodiment, It is also possible to adopt a configuration in which an outer wall portion that does not face the ventilation hole is further provided. Of course, differently from this, it is also possible to adopt a configuration in which the outer wall portion not facing the ventilation hole is not provided.

The cylindrical wall portion of the lid according to the present invention is not limited to a cylindrical shape, and can be changed in accordance with the shape of a portion to be externally fitted. For example, a non-cylindrical shape such as an elliptical cylindrical shape or a rectangular cylindrical shape can be used.
In the above-described embodiment, the lid 2 is attached to the mouth and neck 10 of the container body 1 via the auxiliary member 3, but the present invention is not limited to this. As the auxiliary member, a member having a configuration different from that of the auxiliary member 3 can be used. In addition, the mouth and neck portion 10 of the container body 1 is configured to be able to directly fit the cylindrical wall portion 22 of the lid 2 so that the auxiliary member 3 or another auxiliary member is used. Instead, it is also possible to adopt a configuration in which the lid 2 is directly attached to the mouth and neck 10.

  The bathroom-installed container in the present invention means a container installed and used in a bathroom, and is not limited to a detergent tank. The type of substance contained in the bathroom installation container is not limited, and may be, for example, a bath agent instead of a detergent.
