Description

[Technical Field]

[0001] The disclosed embodiments relate to sanitary ware. [Background technology]

[0002] BACKGROUND ART Conventionally, individual identification information may be displayed on sanitary ware such as urinals, toilet bowls, and washbasins in a position that forms part of the exterior appearance of the sanitary ware.

[0003] In sanitary ware, for example, the tanks of urinals and toilets have lids that are attached to the main body of the urinal or the main body of the flush water tank of the toilet (see, for example, Patent Documents 1 to 3). Individual identification information may be displayed on the lid. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-270563 [Patent Document 2] Japanese Patent Application Publication No. 2019-203340 [Patent Document 3] Japanese Patent Application Publication No. 2019-138022 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in conventional sanitary ware, there is a risk that the display of the individual identification information will deteriorate over time, and if the display of the individual identification information includes a one-dimensional barcode or a two-dimensional barcode such as a QR code (registered trademark), the individual identification information may not be readable.

[0006] An object of one aspect of the embodiment is to provide sanitary ware that makes it easy to secure a position for displaying individual identification information, prevents a decrease in design, and further prevents deterioration over time of the display of individual identification information, thereby preventing errors in reading the individual identification information. [Means for solving the problem]

[0007] A sanitary ware according to one aspect of the embodiment has a display portion including a concave or convex flat surface that displays individual identification information in a position that is hidden from the outside.

[0008] According to this configuration, the display unit includes a concave or convex flat surface on which the individual identification information is displayed, making it easy to secure a position for displaying the individual identification information. For example, if the individual identification information is displayed as a sticker, the sticker can be easily attached. Furthermore, if the display of the individual identification information includes a one-dimensional barcode or a two-dimensional barcode such as a QR code (registered trademark), the occurrence of read failures of the individual identification information can be reduced. Furthermore, by displaying the individual identification information in a position that is hidden from the outside, the display of the individual identification information cannot be seen from the outside. This prevents a loss of design quality due to the display of the individual identification information appearing on the product's exterior. Furthermore, deterioration of the display of the individual identification information over time can be reduced, and if the display of the individual identification information includes a one-dimensional barcode or a two-dimensional barcode such as a QR code (registered trademark), the occurrence of read failures due to deterioration of the display of the individual identification information can be reduced.

[0009] The above-mentioned sanitary ware also has a lid and a main body on which the lid is placed, and the display unit includes a concave flat surface and is arranged on an installation surface of the lid that abuts against the main body when the lid is placed on the main body.

[0010] According to this configuration, the display unit is disposed on the installation surface of the lid that abuts against the main body, so that the display of the individual identification information is not visible from the outside. This prevents the display of the individual identification information from appearing on the product's exterior, thereby reducing the loss of design aesthetics. Furthermore, deterioration of the display of the individual identification information over time can be reduced, reducing the occurrence of read failures due to deterioration of the display of the individual identification information when the display of the individual identification information includes a one-dimensional barcode or a two-dimensional barcode such as a QR code (registered trademark). Furthermore, the concave shape of the display unit reduces deterioration of the display of the individual identification information, such as scratches due to abutment with the main body, reducing the occurrence of read failures due to deterioration of the display of the individual identification information when the display of the individual identification information includes a one-dimensional barcode or a two-dimensional barcode such as a QR code (registered trademark).

[0011] In the above sanitary ware, the lid has a corner where two sides intersect when viewed from the top to bottom, and the display unit is disposed at the corner.

[0012] The corner where the two sides intersect has a larger area than the sides. With this configuration, the display unit is disposed at the corner, making it easier to secure a flat surface for displaying the individual identification information.

[0013] In the above sanitary ware, the indicator is disposed inwardly of the outer surface of the lid.

[0014] With this configuration, the display unit is positioned inward from the outer surface of the lid, so the display of the individual identification information is not visible from the outside. This prevents the display of the individual identification information from appearing on the product's exterior, thereby minimizing the loss of design quality. Furthermore, it is possible to prevent the display of the individual identification information from deteriorating over time, which reduces the occurrence of read failures due to deterioration of the display of the individual identification information when the display of the individual identification information includes a one-dimensional barcode or a two-dimensional barcode such as a QR code (registered trademark).

[0015] Furthermore, in the above-mentioned sanitary ware, the lid portion has an outer surface wall that forms the outer surface, an inner surface wall that is arranged more inward than the outer surface wall, an upper surface wall that forms the upper surface of the lid portion, an installation surface wall that forms the installation surface, and a space portion surrounded by the outer surface wall, the inner surface wall, the upper surface wall, and the installation surface wall, and the display portion is arranged on the inner side of the inner surface of the outer surface wall.

[0016] With this configuration, the display unit is positioned on the inside of the inner surface of the outer surface wall, and since the outer surface wall is present on the outer side of the display unit, it is possible to prevent cleaning water from splashing to the outside from the space located on the inside side of the lid unit.

[0017] In the above-described sanitary ware, the indication portion is a cutout portion of the lid portion that is open on its inner side.

[0018] According to this configuration, the display portion is a notch-shaped portion that is open on the inner side of the lid portion, which makes it easy to form a flat surface when forming the display portion. [Effects of the Invention]

[0019] According to the sanitary ware of one aspect of the embodiment, it is possible to easily secure a position for displaying the individual identification information, to prevent deterioration of the design, and to prevent failure to read the individual identification information by preventing deterioration of the display of the individual identification information over time.

[0021] Hereinafter, embodiments of the sanitary ware disclosed in the present application will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments described below.

[0022] <Overview of Sanitary Ware (Urinals)> First, an overview of a sanitary ware (urinal) 1 according to an embodiment will be described with reference to Fig. 1. Fig. 1 is a schematic perspective view showing an example of a sanitary ware (urinal) 1 according to an embodiment. In this embodiment, a urinal will be used as an example of the sanitary ware 1. Note that the sanitary ware 1 is not limited to a urinal, and may be, for example, a flush toilet (toilet bowl body or flush water tank) or a washbasin.

[0023] Each figure may also show a three-dimensional Cartesian coordinate system including a Z-axis, with the positive direction being the vertically upward (upward). In the following, for convenience of explanation, the positive direction of the X-axis is defined as the left, the negative direction of the X-axis as the right, the positive direction of the Y-axis as the forward direction, and the negative direction of the Y-axis as the backward direction, and the X-axis direction may also be referred to as the left-right direction, the Y-axis direction as the front-back direction, and the Z-axis direction as the up-down direction.

[0024] As shown in Figure 1, the urinal 1, which is a sanitary ware, is, for example, a wall-mounted type that is installed on a wall surface WS of a toilet room. Note that the urinal 1 is not limited to a wall-mounted type, and may also be a floor-standing type that is installed on the floor surface FS of the toilet room.

[0025] The urinal 1 is made of ceramic. However, the urinal 1 is not limited to being made of ceramic, and may be made of resin or a metal such as stainless steel. The urinal 1 may also be made of a combination of ceramic and resin. The urinal 1 comprises a main body 11 and a lid 12. The main body 11 comprises a bowl surface 11a. The bowl surface 11a receives urine from a user standing in front of the urinal 1 (bowl surface 11a).

[0026] The front surface of bowl surface 11a is formed, for example, in an arc shape that opens from the top to the bottom of bowl surface 11a so as to face the user. For example, the top of the front surface of bowl surface 11a may be a substantially flat surface, or a slightly concave curved surface that continues in the left-right direction, and the center may be a concave curved surface that continues in the left-right direction and also in the front-to-back direction.

[0027] The bottom of bowl surface 11a is formed in a bowl shape. At this bottom, bowl surface 11a collects the user's urine and the flushing water discharged from water discharger 2, and directs the urine and flushing water to an outlet (not shown) formed at the bottom. A strainer (not shown) is attached to the outlet. The urine and flushing water that flow into the outlet flows through a trap pipe (not shown) connected to the outlet, and is discharged into a drain pipe (not shown) connected to the trap pipe.

[0028] The water discharger 2 is disposed at the upper front portion of the bowl surface 11a. The water discharger 2 discharges flushing water onto the bowl surface 11a at the upper front portion of the bowl surface 11a. The water discharger 2 constitutes part of the automatic flushing unit (not shown) of the urinal 1.

[0029] The automatic flushing unit comprises a water discharge device 2 and a control device (not shown). The control device controls each part based on, for example, a detection signal from a human body detection sensor that detects the user of the urinal 1 and a predetermined control program. If the urinal 1 has a storage compartment, the control device is installed inside the storage compartment. If the urinal 1 does not have a storage compartment, the control device may be installed, for example, on the back side of the wall WS of the toilet room.

[0030] In addition to the water discharger 2 and the control device, the automatic flushing unit further includes a water supply pipe, a flow rate adjustment valve, an on-off valve, a water supply flow path, and a human body detection sensor, all of which are not shown. The water supply pipe is a pipe that supplies flush water from a water source such as a tap. The flow rate adjustment valve is a valve that is provided in the water supply pipe and opens and closes the water supply pipe. The on-off valve is a valve that is provided in the water supply pipe and supplies and stops flush water. The water supply flow path is a flow path that supplies flush water from the on-off valve to the water discharger 2.

[0031] The human body detection sensor is a sensor that detects a user standing in front of the urinal 1. In the automatic flushing unit, for example, when a user stands in front of the urinal 1, the human body detection sensor detects the user and sends a detection signal to the control device, and when the control device receives the detection signal, the control device recognizes the presence of the user.

[0032] In addition, in the automatic flushing unit, when the user finishes urinating and leaves the front of the urinal 1, and the human body detection sensor goes into a non-detection state, the control device determines that the user has left. When the control device determines that the user has left, it starts the flushing operation.

[0033] The left and right side surfaces of the bowl surface 11a are formed so as to rise forward from both left and right end portions of the front surface of the bowl surface 11a.

[0034] Bowl surface 11a also has shelf portions 11b. Shelf portions 11b are provided on each of the left and right side surfaces of bowl surface 11a. Shelf portions 11b are formed in a stepped shape that protrudes inward from bowl surface 11a and extends downward from the left and right sides of bowl surface 11a to the front of bowl surface 11a. Some of the flush water discharged from water discharger 2 rests on shelf portions 11b, and guides some of the flush water on shelf portions 11b to the front of bowl surface 11a.

[0035] The lid part 12 is attached to the main body part 11. The lid part 12 is attached to the top of the main body part 11. When attached to the main body part 11, the lid part 12 closes an opening (not shown) formed on the top surface of the main body part 11.

[0036] <Lid> Next, the lid of the sanitary ware (urinal) 1 according to the embodiment will be described with reference to Figures 2 to 4. Figure 2 is a schematic bottom view showing the lid 12 of the sanitary ware 1 according to the embodiment. Figure 3 is a cross-sectional view taken along line III-III in Figure 2. Figure 4 is an explanatory diagram of the installed state of the lid 12 of the sanitary ware (urinal) 1 according to the embodiment. Note that Figure 4 is a schematic front cross-sectional view of part A shown in Figure 1.

[0037] 2, the cover 12 has a rectangular outer shape when viewed from above and below. The cover 12 has a plurality of sides 121 and a plurality of corners 122. In the example shown in FIG. 2, the cover 12 has four sides 121, four corners 122, and the display unit 3.

[0038] The four side portions 121 form the four sides of the lid portion 12 when viewed in the vertical direction. Each of the four side portions 121 has a predetermined width. Furthermore, the ends of two side portions 121 intersect to form four corners (corners 122, described below) of the lid portion 12. That is, the corners 122 are formed when two side portions 121 intersect when viewed in the vertical direction.

[0039] As described above, the four corners 122 form the four corners of the lid 12. It is easier to ensure the area of the corners 122, which form the four corners of the lid 12, compared to the side portions 121. As shown in part A in Figures 1 and 2, a display unit 3, which will be described later, is disposed in one of the four corners 122.

[0040] As shown in Fig. 3, the lid part 12 includes a space part 13, an outer surface wall 14, an inner surface wall 16, a top surface wall 17, and a mounting surface wall 19. The space part 13 is a space surrounded by the outer surface wall 14, the inner surface wall 16, the top surface wall 17, and the mounting surface wall 19, which will be described later. The space part 13 is formed along the peripheral part of the lid part 12, which is formed by the side parts 121 and the corner parts 122.

[0041] The outer surface wall 14 forms an outer surface 15 of the lid portion 12. The inner surface wall 16 is disposed a predetermined distance inward from the outer surface wall 14. The top surface wall 17 forms an upper surface 18 of the lid portion 12. As shown in Figures 3 and 4 , the surface of the lid portion 12 that abuts against the main body portion 11 when installed on the main body portion 11 becomes an installation surface 20 of the lid portion 12. The installation surface wall 19 forms the installation surface 20.

[0042] <Display section> Next, the display unit 3 will be described with reference to Figs. 2 to 4. As shown in Fig. 2, the display unit 3 is a portion that displays individual identification information. The individual identification information includes information about the urinal 1 (see Fig. 1) on which this individual identification information is displayed. The individual identification information includes information such as the product number and serial number of the urinal 1. The individual identification information may also include a two-dimensional barcode such as a QR code (registered trademark). Note that the individual identification information may include, for example, a one-dimensional barcode instead of a two-dimensional barcode such as a QR code (registered trademark).

[0043] The individual identification information is, for example, a display medium 4 such as a sticker. The individual identification information is displayed by, for example, attaching a sticker as the display medium 4. Note that the display medium 4 may also be directly printed on the pottery.

[0044] As shown in Figures 3 and 4, the display unit 3 is arranged in a position that is hidden from the outside when the urinal 1 is viewed from the outside. The display unit 3 includes a concave flat surface. Such a concave flat surface serves as a display surface 31 for the individual identification information on the display unit 3. For example, if the display medium 4 for the individual identification information is a sticker, this sticker is affixed to the display surface 31. Note that the display unit 3 may include a convex flat surface (display surface 31) instead of a concave flat surface.

[0045] As shown in FIG. 2, the display unit 3 is disposed on the installation surface 20 of the lid unit 12. The display unit 3 is disposed at a corner 122 of the lid unit 12. As shown in FIG. 3, the display unit 3 is disposed inward of the outer surface 15 of the lid unit 12. The display unit 3 is also disposed on the inner side of the inner surface of the outer surface wall 14. As shown in FIG. 3, the display unit 3 is disposed inward of a reference line L along the inner surface of the outer surface wall 14. The display unit 3 may include the reference line L.

[0046] 3, the display unit 3 is concave and has an open edge on the inner side of the lid 12. In this way, the display unit 3 has a so-called notch shape with the inner side of the lid 12 open.

[0047] A display medium 4, such as a sticker that displays individual identification information, is attached to the display surface 31 of the display unit 3. The display medium 4 is placed one step lower than the installation surface. Therefore, as shown in FIG. 4, the display medium 4 cannot be seen from the outside. Furthermore, the display medium 4 can prevent deterioration of the display of the individual identification information over time.

[0048] As described above, the sanitary ware 1 according to the embodiment has a display unit 3 including a concave or convex flat surface (display surface 31) on which individual identification information is displayed. This facilitates securing a position for displaying the individual identification information, and, for example, when the individual identification information is displayed as a sticker, the sticker can be easily attached. Furthermore, when the display of the individual identification information includes a one-dimensional barcode or a two-dimensional barcode such as a QR code (registered trademark), the occurrence of read failures of the individual identification information can be reduced. Furthermore, by displaying the individual identification information in a position that is hidden from the outside, the display of the individual identification information cannot be seen from the outside. This prevents a loss of design value due to the display of the individual identification information appearing on the product's exterior. Furthermore, this also prevents deterioration of the display of the individual identification information over time, thereby preventing read failures due to deterioration of the display of the individual identification information when the display of the individual identification information includes a one-dimensional barcode or a two-dimensional barcode such as a QR code (registered trademark).

[0049] Furthermore, by disposing the display unit 3 on the installation surface 20 that abuts against the main body 11 of the lid 12, the display of the individual identification information is not visible from the outside. This prevents the design from being impaired by the display of the individual identification information appearing on the product's exterior. This also prevents deterioration of the display of the individual identification information over time, which reduces the occurrence of read failures due to deterioration of the display of the individual identification information when the display of the individual identification information includes a one-dimensional barcode or a two-dimensional barcode such as a QR code (registered trademark). Furthermore, by having the display unit 3 concave, it is possible to prevent deterioration of the display of the individual identification information, such as scratches due to abutment with the main body 11, which reduces the occurrence of read failures due to deterioration of the display of the individual identification information when the display of the individual identification information includes a one-dimensional barcode or a two-dimensional barcode such as a QR code (registered trademark).

[0050] Furthermore, corner 122 where two sides 121 intersect has a larger area than side 121. Therefore, by placing display unit 3 at corner 122, it is easy to ensure a flat surface for displaying individual identification information.

[0051] Furthermore, by positioning the display unit 3 inward from the outer surface 15 of the lid unit 12, the display of the individual identification information is not visible from the outside. This prevents the display of the individual identification information from appearing on the product's exterior, thereby preventing a loss of design. It also prevents the display of the individual identification information from deteriorating over time, and prevents read failures due to deterioration of the display of the individual identification information when the display of the individual identification information includes a one-dimensional barcode or a two-dimensional barcode such as a QR code (registered trademark).

[0052] Furthermore, since the display unit 3 is positioned on the inner side of the inner surface of the outer surface wall 14, the outer surface wall 14 is present on the outer side of the display unit 3, which prevents cleaning water from splashing out from the space 13 located on the inner side of the lid unit 12 to the outside.

[0053] Furthermore, since the display unit 3 is a cutout that is open on the inner side of the cover 12, it is easy to form a flat surface (display surface 31) when forming the display unit 3.

[0054] <Other embodiments> Next, a sanitary ware (flush toilet) 50 according to another embodiment will be described with reference to Figures 5 and 6. Figures 5 and 6 are schematic perspective views showing a sanitary ware (flush toilet) 50 according to another embodiment.

[0055] In the example shown in Figure 5, a flush toilet will be used as an example of sanitary ware 50. As shown in Figure 5, a flush toilet 50 made of ceramic, which is sanitary ware, comprises a toilet body 51. One or both of the left and right side portions 52 of the toilet body 51 are covered, for example, by a cover member 53. Therefore, the side portions 52 of the toilet body 51 are covered by the cover member 53 and cannot be seen from the outside. The display unit 3 is placed on the side portion 52 of the toilet body 51.

[0056] 5, the display unit 3 has a convex flat surface. If the display medium 4 that displays the individual identification information is a sticker or the like, it is attached to this flat surface (display surface 31a).

[0057] According to the sanitary ware 50 of this embodiment, the display unit 3 includes a convex flat surface (display surface 31a) for displaying the individual identification information. This facilitates securing a position for displaying the individual identification information. For example, if the individual identification information is displayed as a sticker, the sticker can be easily attached. Furthermore, if the display of the individual identification information includes a one-dimensional barcode or a two-dimensional barcode such as a QR code (registered trademark), the occurrence of read failures of the individual identification information can be reduced. Furthermore, by displaying the individual identification information in a position that is hidden from the outside, the display of the individual identification information is not visible from the outside. This prevents a loss of design value due to the display of the individual identification information appearing on the product's exterior. Furthermore, this prevents deterioration of the display of the individual identification information over time. Therefore, if the display of the individual identification information includes a one-dimensional barcode or a two-dimensional barcode such as a QR code (registered trademark), the occurrence of read failures due to deterioration of the display of the individual identification information can be reduced.

[0058] In the example shown in Figure 6, a flush toilet will be used as an example of the sanitary ware 50. As shown in Figure 6, the flush toilet 50 made of ceramic, which is sanitary ware, comprises a toilet body 51. One or both of the left and right side portions 52 of the toilet body 51 are covered, for example, by a cover member 53. Therefore, the side portions 52 of the toilet body 51 are covered by the cover member 53 and cannot be seen from the outside. The display unit 3 is placed on the side portion 52 of the toilet body 51.

[0059] 5, the display unit 3 has a concave flat surface. If the display medium 4 that displays the individual identification information is a sticker or the like, it is attached to this flat surface (display surface 31b).

[0060] According to the sanitary ware 50 of this embodiment, the display unit 3 includes a concave, flat surface (display surface 31b) for displaying the individual identification information. This facilitates securing a position for displaying the individual identification information. For example, if the individual identification information is displayed as a sticker, the sticker can be easily attached. Furthermore, if the display of the individual identification information includes a one-dimensional barcode or a two-dimensional barcode such as a QR code (registered trademark), the occurrence of read failures of the individual identification information can be reduced. Furthermore, by displaying the individual identification information in a position that is hidden from the outside, the display of the individual identification information is not visible from the outside. This prevents a loss of design value due to the display of the individual identification information appearing on the product's exterior. Furthermore, this prevents deterioration of the display of the individual identification information over time. Therefore, if the display of the individual identification information includes a one-dimensional barcode or a two-dimensional barcode such as a QR code (registered trademark), the occurrence of read failures due to deterioration of the display of the individual identification information can be reduced.

[0061] In the above embodiments, a urinal or a flush toilet has been described as an example of the sanitary ware 1, 50, but the sanitary ware 1, 50 may also be a flush water tank that stores flush water in a flush toilet. In the case of a flush water tank, a display unit that displays individual identification information is formed on the lid that closes the top opening of the tank body (main body).

[0062] Further advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
