Description

  The present invention relates to a urinal and a transportable toilet provided with the urinal.

There are so-called morning glory type wall-mounted type, floor-standing type stall type, wall-mounted type urinal for men, and a vertically long low lip type such as the stall type. In any of these types, the urinal has a bowl portion that receives a urine flow from the user, and a drain port disposed at the bottom of the bowl portion. Here, the bowl portion has a wall surface of the bowl portion that faces the user and receives a urine flow, an outer wall surface that surrounds the periphery of the wall surface of the bowl portion, and an upper wall surface that extends from the upper end of the wall surface of the bowl portion to the user side. Configured.
In addition to being installed indoors, urinals may be provided in a simple toilet that can be transported to a construction site or an event venue, for example.

  In any of the above urinals, the wall surface of the bowl portion is formed as a flat surface or a gently curved surface, particularly at a location where the urine flow hits. In such a bowl part wall surface, the incident angle of the urine flow with respect to the bowl part wall surface tends to be close to a right angle, and as a result, there is a problem that urine bounces off the bowl part wall surface and scatters in and out of the bowl part.

  In order to solve such a problem, for example, Patent Document 1 discloses a urinal in which urine rebound is suppressed. In this urinal, a convex ridge projecting toward the user is attached to a collision surface on which urine collides. The ridge has an isosceles triangle in horizontal section and is located only at the center of the collision surface. By attaching such a ridge part, the urinal of patent document 1 makes the collision angle of the urine flow when colliding with a ridge part an acute angle, and suppresses the urine rebound.

Japanese Patent No. 4782815

  However, in the urinal of Patent Document 1, the ridge for suppressing rebound of urine is attached only at one central portion of the collision surface as described above. Usually, since the urine flow hits the central part of the urinal, it is estimated that the urine flow inevitably hits the apex of the ridge. In this case, since urine is separated into left and right at the apex of the ridge, it is conjectured that the urine rebound increases. In addition, Patent Document 1 considers that urine hits the urinal with only one incident angle, but in reality, various angles can be considered, and a ridge is simply provided at one location of the urinal. Then, it must be said that it is very difficult to prevent urine bounce. Furthermore, since the ridge is provided in the central portion of the urinal, the distance from the left and right wall surfaces of the ridge to the side wall of the urinal, that is, the outside of the urinal is shorter than the distance from the central portion of the urinal. Therefore, when the urine flow hits other than the apex of the ridge, urine is likely to be scattered outside the urinal.

  The present invention has been made to solve such problems, and provides a urinal that can suppress urine rebound and scatter compared to conventional urinals, and a transportable toilet equipped with the urinal. The purpose is to do.

In order to achieve the above object, the present invention is configured as follows.
That is, the urinal according to the first aspect of the present invention includes a bowl portion that receives a urine flow from a user, and a drain port disposed at the bottom of the bowl portion, and the bowl portion faces the user and the urine flow. A urinal having a wall surface of the bowl portion that hits, an outer wall surface that surrounds the periphery of the wall surface of the bowl portion, and an upper wall surface that extends from the top of the wall surface of the bowl portion to the user side,
The urinal is a blow molded resin material,
A convex part provided on the wall surface of the bowl part, and a convex part extending in the vertical direction of the urinal in a state of projecting toward the user side at two positions symmetrical to the central axis of the urinal,
An arcuate recess located between the two projections and connecting the two projections;
Is further provided.

  The transportable toilet according to the second aspect of the present invention includes the urinal according to the first aspect.

  According to the urinal of the first aspect of the present invention, since the concave portion is formed between the two convex portions and the two convex portions, the curvature of the curved surface of the bowl portion wall surface in the concave portion is urine in the conventional urinal. Larger than the curvature of the flow collision surface, the curve becomes tighter. Therefore, the incident angle of the urine flow with respect to the wall surface of the bowl portion in the concave portion is an acute angle, and the rebound of urine can be suppressed as compared with the conventional case.

In each figure, the same or similar components are denoted by the same reference numerals. In addition, in order to avoid the following description from becoming unnecessarily redundant and to facilitate understanding by those skilled in the art, a detailed description of already well-known matters and a duplicate description of substantially the same configuration may be omitted. . Further, the contents of the following description and the accompanying drawings are not intended to limit the subject matter described in the claims.

1st Embodiment;
In the embodiment described below, a urinal that can be attached to a transportable toilet, for example, used at a construction site or an event venue is taken as an example, but this embodiment is not limited to this and is indoors. The present invention is also applicable to public and household urinals that are installed. In this case, the urinal may be made of earthenware. Further, in the following embodiment, the above-described so-called wall-mounted low-lip type urinal is taken as an example, but this embodiment is not limited to this, and the stall-type or so-called wall-mounted morning glory type is also used. Can be applied.

FIGS. 1 to 4 show an example of a urinal 101 provided in a transportable toilet in the embodiment. The urinal 101 is a urinal attached to the transportable toilet 200 as shown in FIG. 6, and is a low lip type attached to the mounting surface 201 of the transportable toilet 200 in a wall-mounted manner.
Further, the urinal 101 is produced by blow molding a thermoplastic resin material including, for example, a polyethylene material in a mold so as to be integrally molded. Moreover, the weight of the urinal 101 is about 2 kg as an example.

  Such a urinal 101 includes a bowl portion 110 that receives a urine flow from a user, and a drain port 150 disposed at the bottom of the bowl portion 110. The bowl portion 110 has a bowl portion wall surface 112, an outer wall surface 114, and an upper wall surface 116, and these wall surfaces are integrally molded to form the bowl portion 110. Here, the bowl portion 110 corresponds to the range indicated by “h1” in FIG. 1 and refers to the range from the upper end 116a of the urinal 101 to the upper end of the drainage port 150.

  The bowl portion wall surface 112 is a wall surface facing the user, and particularly corresponds to a wall surface on which the user's urine flow hits. 3A and 3B (also collectively referred to as FIG. 3), the bowl portion wall surface 112 is a portion corresponding to the range L in the vertical direction 101a of the urinal 101. Here, the upper end in the range L corresponds to the step 140 located at the upper end of the bowl portion wall surface 112, and the lower end corresponds to the bottom portion of the bowl portion 110, specifically, the upper end of the drain port 150. Here, the step 140 corresponds to a boundary portion between the bowl wall surface 112 and the upper wall surface 116, and corresponds to an example of a water flow adjustment protrusion in the case where the urinal 101 is a flush type as will be described later, and a portion for adjusting the water flow direction. It is. Note that the step 140 is formed even in the non-washing type.

The outer wall surface 114 is a wall surface that surrounds the periphery of the bowl portion wall surface 112, and is a wall surface mainly located on both the left and right sides of the bowl portion wall surface 112.
The upper wall surface 116 is a wall surface extending from the upper part of the bowl portion wall surface 112 toward the user side.

  In the molded body immediately after molding due to blow molding, the opening 109 (FIG. 3A) is not formed, and the bowl portion 110 is not exposed. Therefore, after blow molding, the front part which is an unnecessary part is cut off from the molded body, and the urinal 101 having the opening 109 as shown in FIG. 3A and exposing the bowl part 110 is produced.

  Further, in the bowl portion 110, a flow path 143 (FIGS. 1 and 2F) is provided near the boundary between the bowl portion wall surface 112 and the outer wall surface 114, which is effective particularly in the washing type and for the flow of washing water.

  Furthermore, the bowl part wall surface 112 has two convex parts 120 projecting from the bowl part wall surface 112 to the user side, and a concave part 130 positioned between the two convex parts 120. Each convex part 120 and the concave part 130 are integrally formed with the bowl part wall surface 112.

  As shown in FIG. 1, the convex portion 120 is a portion formed by projecting toward the user side 104 with the ridgeline 103 as two ridges 103 positioned symmetrically with respect to the central axis 102 of the urinal 101. Yes, the urinal 101 is continuously extended in the vertical direction 101a and molded. Such a convex portion 120 can be formed over the entire range of the bowl portion wall surface 112 in the vertical direction 101a, that is, the above-described range L. Here, the convex portion 120 may have a constant protruding height over the range L.

  On the other hand, as shown in the present embodiment, the convex portion 120 has a vertical shape as shown in FIGS. 2A to 2H (generally referred to as FIG. 2) or when the convex portion 120 is viewed from the side. In the direction 101a, as shown in FIG. 2A to 2H show cross sections of the urinal 101 in the horizontal direction 101b, that is, in the horizontal direction, at positions A to H shown in FIG.

  Referring to FIG. 2, the height of the convex portion 120 at the ridgeline 103 from the back surface 105 of the urinal 101 is the upper part of the urinal 101, in other words, as can be seen particularly from FIGS. 2B to 2G. 1 gradually increases from the upper end of the range L to the approximately C position shown in FIG. 1, is highest at the approximately C position, and gradually decreases from approximately the C position to approximately the G position shown in FIG. Each convex part 120 is molded in such a form. In other words, the convex portion 120 is formed from the upper portion of the urinal 101 along the ridgeline 103 to a substantially G position. The back surface 105 is a surface in contact with the mounting wall surface on which the urinal 101 is installed.

More specifically, the convex part 120 exists in the range “L1” in the vertical direction 101a between the M position and the N position shown in FIG. 3A in this embodiment. Here, the M position corresponds to the position of the central axis 102 of the urinal 101 in the upper end of the bowl wall surface 112 existing corresponding to the range “L” as described above, and the N position is the bowl wall surface 112. This corresponds to the inflection position at. That is, the bowl portion wall surface 112 has a circular arc surface 117 (FIG. 3A) at the lower portion thereof, and the circular arc surface 117 is an arc surface located at the lower portion of the urinal 101 and connected to the drain port 150. Therefore, the inflection position corresponds to a position where the tangent line on the circular arc surface 117 included in the bowl wall surface 112 becomes a vertical line.
FIG. 3A shows a cross section along the central axis 102 of the JJ portion shown in FIG. Further, as shown in FIG. 1, the convex portion 120 is located away from the central axis 102 in the left-right direction 101 b. Therefore, the line segment expressing the convex portion 120 in FIG. 3A represents the side surface of the convex portion 120 and does not indicate the cross section.

The range L1 corresponding to the position between the M and N positions corresponds to about 70 to 80% of the above-described range “h1” (the range in the vertical direction 101a of the bowl portion 110). Further, when the M position is the starting point in the vertical direction 101a, the top 121 (FIG. 3) where the height of the convex portion 120 from the back surface 105 at the ridgeline 103 is the largest from about 30% of the range “L1”. It is located between about 80%.
Here, when the top part 121 is located at less than 30%, in other words, when the top part 121 is close to the M position, the degree that the convex part 120 contributes to prevention of scattering of urine becomes very low. In addition, a molding problem also occurs, and when the urinal 101 is a flush type, there is a manufacturing problem that it is difficult to attach the nozzle 145 (FIG. 5B) for flowing water to the step 140.
On the other hand, when the top part 121 is located in excess of 80%, in other words, when the top part 121 is close to the N position, it is expected that the ratio of urine hitting the top part 121 is expected to increase, and there is a concern that urine scattering may increase. The In addition, when the urinal 101 is a flush type, there is a possibility that flowing water may be affected.

  Moreover, the height of the convex part 120 from the back surface 105 in the ridgeline 103 is a dimension of about 20% to about 30% with respect to the depth length W (FIG. 3A) in the depth direction 101c of the urinal 101. If the height of the convex portion 120 is less than 20%, it becomes difficult to maintain the shape of the concave portion 130 between the two left and right convex portions 120, and the effect of preventing urine scattering and rebounding is reduced. Moreover, when the height of the convex part 120 exceeds 30%, the clearance gap between the convex part 120 and the outer side wall surface 114 will become small, and it seems that trouble will arise on maintenance, such as cleaning. Therefore, the urine bounce can be more effectively suppressed by setting the height of the convex portion 120 in the above-described range.

Further, the distance X1 (FIG. 1) between the ridge lines 103 of the two convex portions 120 in the left-right direction 101b is a value between about 30% and about 60% with respect to the full width X (FIG. 1) of the urinal 101. Is set.
Here, when the two convex portions 120 are arranged at a distance X1 of less than 30%, the concave portion 130 located between the two convex portions 120 is narrowed, so that the urine flow to a place other than the concave portion 130. The possibility of being located increases. As a result, it is imagined that urine scattering increases.
On the other hand, when the two convex portions 120 are arranged at a distance X1 exceeding 60%, each convex portion 120 is positioned close to the outer wall surface 114. Therefore, it seems that the clearance gap between the convex part 120 and the outer side wall surface 114 becomes small, and troubles occur in maintenance such as cleaning.

  The concave portion 130 is positioned between the two convex portions 120 molded as described above, and more specifically, is positioned between the ridge lines 103 of the convex portions 120, and has an arc shape that integrally connects both the convex portions 120. This is a portion having a curved surface. As is clear from FIG. 1, the recess 130 positioned between the ridge lines 103 exists in the center of the urinal 101 along the central axis 102, and in the present embodiment, the recess 130 is approximately in the left-right direction 101 b of the urinal 101. Occupies more than half. Further, in the case of an adult user, it is expected that the urine flow hits the bowl wall surface 112 between about the D position and about the F position with the E position shown in FIG. 1 as the center.

  Thus, in the urinal 101 of this embodiment, the recessed part 130 formed between the ridgeline 103 of each convex part 120 by forming the convex part 120 in two places of the bowl part wall surface 112 along the up-down direction 101a. 2C and 2D, for example, the curvature of the curved surface of the bowl portion wall surface 112 becomes larger than the curvature of the urine flow collision surface in the conventional urinal, that is, the curve becomes tight. Moreover, the recessed part 130 located between the ridgelines 103 occupies about half or more of the width | variety in the left-right direction 101b of the urinal 101 as mentioned above. Therefore, the incident angle of the urine flow with respect to the wall surface 112 of the bowl portion in the concave portion 130 becomes an acute angle, so that the urine rebound can be suppressed as compared with the conventional case, and as a result, scattering outside the bowl portion 110 can also be suppressed.

Further, since the convex portions 120 are arranged at two places on the left and right sides of the bowl wall surface 112, and the concave portion 130 is located in the central portion of the urinal 101 corresponding to the convex portions 120, the urinal 101 is used by the user. A psychological effect that makes the user want to urinate so that the urine flow hits the central portion of the urinal 101 can also be caused. Further, in order to easily cause such a psychological effect, the upper wall surface 116 has a curved portion 118 that is recessed from the user side 104 to the back surface 105 so that the user can easily see the convex portion 120 and the concave portion 130. (FIG. 2A, FIG. 4) is provided.
As a result, compared to the urinal of Patent Document 1 described above, even when urine is scattered, the urine scattering distance is physically shortened, and urine can be prevented from scattering outside the urinal 101. .

  Furthermore, since the concave portion 130 exists in the valley between the two convex portions 120, even if the urine flow rebounds at the bowl wall surface 112 of the concave portion 130, the bounced urine remains on the wall surface of the convex portion 120 located on both sides. In this case, it is also possible to prevent scattering to the outside of the recess 130. This also makes it possible to reduce urine scattering to the outside of the bowl portion 110 as compared to the conventional case.

In the shape as described above, in particular, the bowl portion wall surface 112, the convex portion 120, and the concave portion 130 are formed. On the other hand, in general, when designing the surface of an object, particularly a curved surface, there is a technique for defining the cross-sectional shape at three positions on this surface and connecting the cross-sectional shapes at these three positions to design the surface of the object. is there.
The surface constituting the bowl wall surface 112 having the convex part 120 and the concave part 130 can also be designed using this method.
That is, as the position corresponding to the above-described three positions, the above-described M position, the position of the top 121 of the convex portion 120 (herein referred to as “T” position), and the above-described N position are used in the vertical direction 101a. . As parameters defining the cross section at each of these positions, distances w1, w2, and w3 from the back surface 105 in the depth direction 101c of the urinal 101 at the following three points I, II, and III in the left and right direction 101b are used. Here, the point I is the position of the concave portion 130 on the central axis 102 of the urinal 101, the point II is the position on the ridge line 103 of the convex portion 120 on one side, and the point III is between the ridge line 103 and the outer wall surface 114. This is the position of the valley 106. The distances w1, w2, and w3 can take values between the maximum value and the minimum value, respectively.
FIG. 8 shows the distances w1, w2, and w3 at the three points I, II, and III at the M position, the T position, and the N position, respectively.

  Therefore, the surface which comprises the bowl part wall surface 112 which has the convex part 120 and the recessed part 130 is formed by connecting each cross section based on distance w1, w2, w3 in each of M position, T position, and N position. It is a curved surface. Further, the curved surface formed in this way is deformed by a value that is variable between the above-mentioned maximum value and minimum value.

  Although the urinal 101 demonstrated above is a form which does not provide the water-washing function, a water-washing function can also be attached. In this case, a pipe is protruded from the upper wall surface 116, and a manual faucet having a handle is attached to the pipe. Also, as shown in FIGS. 5A and 5B (also collectively referred to as FIG. 5), the water flowing into the bowl 110 through the faucet can flow uniformly over the entire wall surface 112 of the bowl. Further, a step 140 for adjusting the water flow flowing through the nozzle 145 connected to the faucet may be formed on the bowl wall surface 112.

  The step 140 has a mountain shape having each inclined portion 141 inclined downward from the central axis 102 of the urinal 101 toward the left and right outer wall surfaces 114. Therefore, the water that has flowed into the apex portion flows downward along the central axis 102, and can flow downward along the wall surface 112 of the bowl portion while being guided by the inclined portions 141. Therefore, by providing the step 140, water can flow over the entire surface of the bowl portion wall surface 112 in the left-right direction 101b.

A second embodiment;
Next, a transportable toilet according to the second embodiment of the present invention will be described.
The urinal 101 described above can be mounted in a box of the transportable toilet 200 as shown in FIGS. 6 and 7. In FIG. 7, the urinal 101 shows a flush type, but it may be a non-flush type. Further, although the S-shaped trap pipe 210 is connected to the drain port 150, a straight pipe may be connected. The trap pipe 210 and the straight pipe are connected to a tank installed below the floor surface 202.

  It is also possible to adopt a configuration in which the above-described modifications are combined.

  The present invention can be applied to a urinal and a transportable toilet provided with the urinal.
