Technical Field

[0001] This application relates to the field of prefabricated toilet technology, and more particularly to a third toilet system. Background Technology

[0002] With societal development and the growing demand for inclusive environments, the construction of accessible restrooms has become increasingly important. Accessible restrooms are designed to provide convenience for special groups, including but not limited to the elderly, children, people with disabilities, and adults requiring companionship. However, current accessible restrooms face a series of challenges in design and implementation: to meet diverse needs and regulatory requirements, they often require substantial space. Therefore, existing accessible restroom technologies have room for improvement in space utilization efficiency. It is necessary to develop a new design scheme for accessible restrooms to enhance the user experience and safety, and better serve special groups. Summary of the Invention

[0003] This application provides a third restroom system that optimizes space utilization and reduces space waste.

[0004] A first aspect of this application provides a third restroom system, the system comprising:

[0005] Wheelchair turning space, functional modules;

[0006] The turning space is the minimum circumference range required for the wheelchair to complete a 360-degree rotation;

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Unless otherwise stated, "a plurality of" means two or more.

[0036] Before explaining the technical solutions of the embodiments of this application, the inventive concept of the embodiments of this application will be explained first.

[0037] The widespread adoption of accessible restrooms is crucial for meeting the sanitation needs of special groups, reflecting society's emphasis on inclusivity and humanistic care. However, current accessible restroom designs face several challenges in their design and implementation. Existing designs often feature multiple functions, with facilities for both adults and children being overly complex and poorly guided, leading to confusion and even safety hazards, such as bumps and falls, for users, especially the elderly, children, and people with disabilities. While the spatial layout of accessible restrooms meets wheelchair turning radius standards, the layout outside this radius is often scattered due to building contours, making spatial navigation and operational guidance for wheelchair users unclear. Furthermore, the combination and arrangement of various sanitation facilities, along with the need to meet diverse regulatory requirements, often necessitates a large footprint for accessible restrooms, increasing costs and limiting their construction and widespread adoption within limited spaces.

[0038] Furthermore, toilets in my country are traditionally divided into men's and women's restrooms, but calls for the construction of third-gender restrooms are growing. In fact, simply separating toilets into men's and women's sections also presents many inconveniences.

[0039] For example, a woman might be out with her three- or four-year-old son, or vice versa, a man with his three- or four-year-old daughter. The parents might want to use the restroom but are hesitant to leave the child alone outside, yet fear bringing the child into the restroom might offend the opposite sex inside. Similarly, when children take their elderly, dependent parents out, and the parents need to use the restroom and require assistance from their children, a similar awkward situation can arise. Furthermore, some disabled individuals also require special restrooms due to privacy or convenience concerns.

[0040] Therefore, based on the above problems, this application proposes a third restroom to address the issues of functional complexity, complex facilities and equipment, and excessive floor space required in existing third restrooms. For example, the usable area of ​​this application embodiment is 3.957m². 2 Compared to the traditional standard area of ​​6.5m² for a third restroom 2 The invention reduces the usable area by approximately 40%, maximizing space utilization. Specifically, the embodiments of this application adopt a modular design concept, dividing the bathroom into several functional modules, arranged in an orderly fashion around a circle with a wheelchair turning diameter of 1500mm as the center. That is, the wheelchair turning space occupies an area of ​​approximately 1.77m². 2 The remaining space in this embodiment can be used to design functional modules and place other facilities, optimizing space utilization and reducing space waste. Compared with related accessible restrooms, the accessible restroom provided in this embodiment achieves effective space saving while ensuring functionality. This design not only improves the user experience for special groups but also has high flexibility and scalability, providing an innovative solution for achieving an efficient, safe, and humanized toilet environment.

[0041] This application embodiment proposes a third restroom system, the system comprising:

[0042] Wheelchair turning space, functional modules;

[0043] The turning space is the minimum circumference required for the wheelchair to complete a 360-degree rotation; the functional modules are placed sequentially around the circumference corresponding to the radius of the turning space, with the turning space as the center; and the functional modules are designed independently of each other.

[0044] For example, such as Figure 1 The wheelchair swivel area (11) is a space designed for wheelchair users, large enough to allow a wheelchair to rotate 360 ​​degrees without moving. This allows users to easily turn in different directions after entering the restroom, facilitating the use of various sanitary facilities without needing to move.

[0045] In some embodiments, the wheelchair turning space 11 is a circular space with a diameter of 1500 mm.

[0046] There are several important reasons for designing the wheelchair turning space in a circular shape rather than the traditional square shape in a third restroom system:

[0047] First, the circular design eliminates the four corners present in the square space, allowing the wheelchair to move freely in any direction without any blind spots. Furthermore, the circular space provides the wheelchair with a uniform range of motion, enabling it to rotate 360 ​​degrees without moving, which is very important for users with mobility impairments.

[0048] Secondly, the four corners of a square space often become unusable space, while a circular space can make better use of every inch of space, reducing space waste. In addition, the design of a circular space is more compact, providing enough activity space in a smaller area, thus minimizing the overall area of ​​the third restroom.

[0049] In addition, the circular space has no sharp corners, reducing the risk of users colliding with the walls during movement and improving safety. At the same time, the smooth edges of the circular space make the wheelchair move more smoothly and reduce the instability that may be caused by sudden turns.

[0050] Furthermore, circular spaces give people a softer and more natural feeling. Compared with square spaces, circular spaces bring more visual comfort, and they also give people a more open and comfortable psychological feeling, reducing the sense of oppression that users feel in small spaces.

[0051] Finally, the circular space facilitates the arrangement of functional modules around it, making the transition between each functional module more natural and smooth. Furthermore, the design of the junction wall being tangent to the outer circle makes the spatial layout more harmonious and unified, avoiding rigid division and improving the overall aesthetics of the space.

[0052] In summary, this circular design maximizes the range of motion for wheelchair users and reduces the wasted space at the four corners of a square design. The circular space design takes into account the size of the wheelchair and the user's ease of use, ensuring sufficient space while minimizing the total area of ​​the accessible restroom.

[0053] The functional modules are arranged sequentially around a central rotating space, ensuring that users can easily move from one functional area to another while rotating. This enclosed layout harmonizes the modular form with the space, creating visual continuity around the circular modular space design and enhancing the overall aesthetic appeal of the space.

[0054] By placing the central turning space and arranging the functional modules around it compactly, space utilization efficiency is greatly improved. This design provides ample space to ensure that wheelchair users can easily turn 360 degrees and access various functional modules, such as the washing and urination modules.

[0055] In addition, each functional module is designed independently and can be flexibly configured according to actual needs.

[0056] First, the independently designed functional modules can be flexibly configured according to the actual needs of different places. For example, some places may need more handwashing facilities, while other places may need more toilets or urinals. The independent design allows the number and layout of each module to be adjusted according to specific needs.

[0057] Secondly, different user groups have different needs, and independently designed functional modules can be customized according to the needs of specific user groups to better meet the needs of different users.

[0058] In addition, the independently designed functional modules can be optimally laid out according to the actual space conditions, avoiding space waste caused by fixed layouts, and can be compactly designed as needed to reduce ineffective space, so that the overall area of ​​the third restroom can be minimized.

[0059] Meanwhile, each functional module can be equipped with corresponding safety measures according to its specific function, such as anti-slip flooring and handrails, to further improve safety. Independently designed functional modules can also reduce mutual interference between different functional areas and improve the user experience.

[0060] The third restroom system proposed in this application minimizes the floor space of the third restroom by integrating the area occupied by various functional modules. While meeting the basic needs of people with mobility impairments, it improves space utilization efficiency and maintains functionality and comfort, making it easier to construct and promote. This minimized space design reduces construction and renovation costs, and makes it easier to integrate into existing building structures, whether for new construction or renovation projects.

[0061] In addition, smaller accessible restrooms have a wide range of applications and are easier to place in locations that are easily accessible to users, such as near entrances or main activity areas.

[0062] like Figure 2 Examples of the multiple functional modules included in a third restroom are as follows:

[0063] The first-size wash module 13, the first-size urinal module 12, the second-size wash module 14, the second-size urinal module 15, the first-size toilet module 17, and the second-size toilet module 16, etc.

[0064] For example, such as Figure 3As shown, the functional modules are separated by a junction wall 21, which has rounded corners and is tangent to an outer circle 111. The outer circle is a circle surrounding the rotation space and larger than the rotation space. The outer circle 111 is represented by a solid line, and the circle 112 of the rotation space is represented by a dashed line.

[0065] In geometry, "tangency" refers to the state where a straight line or curve is in contact with another curve or figure but does not intersect. In other words, tangency means that there is only one point of contact between the two lines, and at this point of contact, the tangents to each line are collinear.

[0066] For example, in this embodiment of the application, the junction wall being tangent to the outer circle means:

[0067] When the edge of the rounded corner junction wall just touches the outer circle, and at this point of contact, the tangent direction of the edge of the junction wall and the outer circle is the same, this is what is meant by the junction wall being tangent to the outer circle as described in the above embodiment. This means that the edge of the junction wall and the outer circle have only one point of contact, and at this point, the tangent direction of the edge of the junction wall and the outer circle is consistent.

[0068] For example, such as Figure 4 This shows a schematic diagram of the wheelchair turning space being tangent to the junction wall.

[0069] Assume that the center of the rotation space is point O, and the center of the outer circle is also point O.

[0070] A section of the edge of the junction wall 21 is tangent to the outer circle at point P, and point P is the only point of contact between the junction wall and the outer circle 111.

[0071] This design ensures that the edges of each connecting wall are tangent to the outer circle, guaranteeing a natural and smooth transition between functional modules while avoiding the creation of unused space.

[0072] Furthermore, ensuring spatial continuity minimizes the obstruction of side walls to users' limb movements even in extremely small spaces, providing convenience for wheelchair users and other special groups, enabling them to quickly access functional spaces, reducing the risk of accidental injury, and improving safety.

[0073] In a third restroom system, "connection wall 21" refers to a wall or partition used to separate different functional modules. Specifically, the main function of the connection wall is to separate different functional areas of the restroom (such as toilet module, urinal module, washbasin module, etc.) to ensure that each module has independent space and avoid interference between functional areas.

[0074] For example, there is a dividing wall between the urinal module and the washroom module to distinguish these two different functional areas. The dividing wall not only helps to divide the internal space of the toilet, giving each functional module a clear boundary for easy management and use, but also ensures that users do not interfere with each other when using different functional modules.

[0075] Furthermore, the rounded corners of the junction walls reduce sharp edges, improving safety and reducing the risk of injury from collisions. The design of the junction walls being tangent to the outer perimeter is not only aesthetically pleasing but also ensures spatial continuity and fluidity, improving space utilization efficiency and creating a more natural transition in the bathroom's layout, avoiding abrupt divisions. The rounded corners are specifically designed to create a smooth, rounded transition at the wall edges where modules meet, preventing sharp corners and further enhancing safety.

[0076] For example, the connecting wall between modules is tangent to the outer circle of the wheelchair turning space, forming a smooth transition and enhancing the overall aesthetics and continuity of the space. Furthermore, it optimizes the spatial layout between modules, making the transitions between functional areas more natural and improving space utilization efficiency.

[0077] The modular spatial design surrounding the wheelchair turning area creates visual continuity and enhances the overall aesthetic appeal of the space.

[0078] In these functional modules, the longest portion protruding from each module towards the rotation space does not extend into the circumference corresponding to the radius of the rotation space. This avoids affecting the space for wheelchair users. This ensures that wheelchair users always have a complete 360-degree rotation space during turns, preventing space restrictions caused by the protruding portions of the functional modules.

[0079] In addition, the sanitary ware in the accessible restroom should be rationally arranged, with the front edge of each fixture within each module ensuring it does not exceed the turning radius, thus guaranteeing the integrity of the turning radius area and ensuring ease of use. A rational spatial layout can also reduce the risk of falls for wheelchair users, improving safety.

[0080] Because the protruding parts of the functional modules do not intrude into the turning space, wheelchair users are not at risk of colliding with the protruding parts when turning, thus improving safety. This reduces the likelihood of users having to make additional adjustments or move due to insufficient space, lowering the risk of falls and other accidental injuries.

[0081] This design not only makes it easier for wheelchair users, but also makes it easier for other users who need assistance (such as the elderly, pregnant women, etc.) to use these facilities.

[0082] The functional module design makes full use of the available area around the turning space, so that the third restroom can meet its functional requirements while minimizing its footprint.

[0083] For example, the functional modules are arranged sequentially around a circle corresponding to the radius of the wheelchair turning space, with the turning space as the center; the layout of each functional module is as follows: Figure 1 As shown, opening the door to the third restroom reveals a large circular wheelchair-turning space, where the layout of the functional modules is clearly visible, making it easy to locate the desired area. On the left is the first-size urinal module 12, and arranged sequentially around the circular wheelchair-turning space are the first-size washroom module 13, the second-size washroom module 14, the second-size urinal module 15, the second-size toilet module 16, and the first-size toilet module 17.

[0084] For example, the internal structure of each functional module is as follows.

[0085] The first-sized urinal module 12 and the second-sized urinal module 15 include at least: a urinal and a flushing system.

[0086] The first-sized wash module 13 and the second-sized wash module 14 include at least: a washbasin and a faucet.

[0087] For example, the planes of the urination module and the washbasin module can be designed as semi-circles.

[0088] Compared to rectangular or other polygonal designs, semi-circular designs make the space more compact, reducing wasted space and allowing functional modules to be arranged more compactly within a limited space, improving space utilization. Furthermore, semi-circular designs reduce corner space, making cleaning easier and reducing hard-to-reach areas; the smooth edges also prevent dust and dirt from accumulating, keeping the bathroom clean.

[0089] For example, the first-sized toilet module 17 and the second-sized toilet module 16 have chamfered rectangles in their planes, and include at least: a toilet seat, a nursing table, a tissue box, and a trash can;

[0090] Among them, the chamfered rectangle is a quadrilateral with all four corners being arc-shaped.

[0091] The chamfered rectangle layout serves a similar purpose to the semi-circular module design mentioned above, allowing the modules to be arranged more compactly within a limited space, thus improving space utilization efficiency.

[0092] In this embodiment, the semi-circular design of some modules minimizes corner space, making the space more compact and suitable for situations requiring maximum space utilization. The chamfered rectangular design of some functional modules aims to reduce unused space while maintaining a rectangular layout, suitable for applications that need to maintain a rectangular layout to some extent. It is clear that the toilet module requires more space, hence the chamfered rectangular planar design. The urinal and washbasin modules, on the other hand, have relatively smaller areas, hence the semi-circular planar design.

[0093] In addition to the several functional modules surrounding the wheelchair turning space 11, such as Figure 3 As shown, the third restroom also includes:

[0094] Box 25 and door 22 of the third restroom.

[0095] For example, the door width can be set to 800 mm, which meets accessibility design standards. It should also have a two-way opening mechanism and be equipped with an automatic door sensor system.

[0096] The door clearly displays a sign indicating it's a third-gender restroom. Third-gender restrooms differ from traditional restrooms, for example... Figure 2 The sign shown is for a third restroom, also known as a "family restroom." As can be seen from the sign, there are signs for men, women, children, and wheelchairs.

[0097] The toilet or urinal module in the third restroom also includes: handrail 23. The handrail is an auxiliary facility installed near the toilet or urinal module to help users stand, sit or turn around.

[0098] The handwashing module in the third restroom also includes:

[0099] Mirror 26 is tilted downward at a preset angle to meet the usage needs of wheelchair users.

[0100] For example, the tilt preset angle can be preset to 10 degrees.

[0101] For example, the mirror 26 is installed at a low position so that wheelchair users can easily see their full appearance; in addition, to facilitate viewing by wheelchair users, the mirror 26 is designed to tilt downwards at a certain angle, usually between 5 and 15 degrees, which makes it easier for people sitting in wheelchairs to see their reflection in the mirror.

[0102] For example, mirror 26 typically has a large width so that wheelchair users can see their entire body.

[0103] For example, mirror 26 is typically made of shatterproof safety glass or acrylic material to reduce the risk of injury to the user if it breaks.

[0104] The tilt angle of the mirrors 26 can be designed to be adjustable, which means that the tilt angle or even the height can be adjusted to accommodate users with different body conditions and heights.

[0105] For example, the width should be at least large enough to accommodate the entire body of a wheelchair user; a width of at least 800 mm is generally recommended.

[0106] For example, the bottom of the mirror 26 is approximately 700mm to 900mm above the ground to accommodate wheelchair users of different heights.

[0107] For example, mirror 26 can be tilted downwards by 10 degrees to accommodate the view of a wheelchair user.

[0108] For example, it can be installed in a fixed position or designed to be angle-adjustable. In addition, it is necessary to ensure that there is sufficient space around the mirror 26 for the wheelchair user to move freely, and that there are no obstacles obstructing the view in front of the mirror 26.

[0109] Having understood the layout of each module and the basic sanitary facilities it contains, the following is a brief introduction to the characteristics of each sanitary facility within each functional module, along with an example size and layout.

[0110] like Figure 3 For example, the first-sized urinal module 12 has a semi-circular plane and includes at least:

[0111] First-size urinal 121, handrail 23, flushing system.

[0112] For example, the first-sized urinal 121 may also be referred to as an accessible urinal.

[0113] Size 121 urinals refer to urinal facilities specifically designed for people with mobility impairments, aiming to improve ease of use and safety. This design typically takes into account the needs of people with disabilities or the elderly, ensuring they can use these facilities more easily. Below are some characteristics and requirements of accessible urinals:

[0114] The height of a size 121 urinal needs to meet specific standards, typically being lower than a standard urinal so that wheelchair users can easily access it. In the United States, according to the Americans with Disabilities Act (ADA), the top of the urinal should not exceed 17 inches (approximately 43 centimeters) from the ground.

[0115] To facilitate wheelchair access, the accessible urinal has ample open space in front, allowing wheelchair users to easily approach and use it. The wheelchair turning space is also designed to allow for easy entry and exit.

[0116] For example, the accessible urinal is equipped with a handrail 23, such as Figure 3 As you can see, the accessible urinal has handrails in two directions: one handrail on each side of the urinal, and another handrail perpendicular to the two side handrails to help the user maintain balance.

[0117] The operating mechanism of the urinal should be easy to understand and use. For example, the first-size urinal 121 has an automatic sensor flushing system, reducing the need for manual operation by the user.

[0118] For example, accessible urinals can also be equipped with an emergency call button so that help can be sought in case of an accident.

[0119] It should be understood that Figure 3 The document shows only a portion of the components; other components such as trash cans, flushing systems, and faucets are not shown.

[0120] Separated from the first-sized urinal 121 by the junction wall 21 is a first-sized wash module 13, wherein the first-sized wash module 13 has a semi-circular plan and includes at least:

[0121] The first-sized washbasin is 131, the faucet is 23, the handrail is 26, and the mirror is 26.

[0122] The first-size washroom module 13 and the first-size urinal module 121 are specifically designed for people with mobility impairments.

[0123] For example, the first-sized handwashing module 13 may be referred to as an accessible handwashing module.

[0124] For example, the height of a first-size washbasin needs to meet specific standards to ensure that wheelchair users can easily access and use it. In the United States, under the Americans with Disabilities Act (ADA), the highest edge or bottom of a washbasin should not be more than 34 inches (approximately 86 centimeters) above the ground.

[0125] The depth of a standard washbasin should not be too deep to avoid making it difficult for the user to reach or extend their arm to use it. Generally, the distance from the front edge of the washbasin to the wall (i.e., the depth of the washbasin) should not exceed 19 inches (approximately 48 centimeters).

[0126] There are no strict rules regarding the width of a standard washbasin, but it should be wide enough to accommodate normal handwashing. Generally, the width should be between 16 and 24 inches (approximately 40 to 61 centimeters).

[0127] To facilitate wheelchair access, the first-size washroom module 13 needs sufficient open space in front to ensure that wheelchair users can easily access and use it. Furthermore, sufficient space for turning around is also required so that wheelchairs can easily enter and exit.

[0128] For example, the washbasin mentioned in this application embodiment is equipped with a handrail 23 on each side to help the user maintain balance or get up and sit down.

[0129] For example, a sensor-operated faucet design can be used to simplify operation. Alternatively, a touch-sensitive faucet design can also be used.

[0130] For example, the accessible handwashing module may also include other assistive facilities, such as non-slip mats, hand sanitizer, etc., to improve the comfort and safety of use.

[0131] For example, the first-sized wash module 13 has a tissue box 20 for storing tissues for use.

[0132] For example, the tissue box 20 is embedded in the first-sized handwashing module 13, and can be rectangular or other shapes.

[0133] To the left of the first-size wash module 13 is the second-size wash module 14, which is smaller than the first-size wash module 13. The two are designed for different groups of people.

[0134] For example, the second-sized wash module 14 has a semi-circular plane and includes at least:

[0135] Second size: washbasin 141, faucet, mirror 26.

[0136] For example, the second-sized washbasin 141 is located at the center of the semi-circular plane.

[0137] For example, the faucet can be a sensor faucet, installed above the sink in a central position, so that the user can easily control the water flow.

[0138] For example, the mirror 26 is installed on the wall directly in front of the sink at a suitable height to ensure that the user can clearly see their face.

[0139] For example, a lighting fixture can be installed above the mirror 26 to provide sufficient light.

[0140] The height of the second-sized wash module 14 is designed according to the average height of children, ensuring that children can easily access and use it.

[0141] For example, the height of the second-size washbasin 141 is approximately 24 inches (about 61 cm), but the actual height needs to be determined based on the average height of children in the target age group.

[0142] The second-sized washroom module 14 needs sufficient space to allow children to move freely. Considering the smaller size of children, the required space will be less than that for adults.

[0143] Safety is paramount for the second-sized wash module 14. For example, the edges and corners should be rounded to prevent children from bumping into them and getting injured, and the faucet should be designed to be easy to operate and have a controllable temperature to prevent scalding.

[0144] For example, the faucet of the second-sized wash module 14 should be designed to be easy to operate, such as using a sensor faucet, to reduce the difficulty of operation for children.

[0145] For example, the second-sized handwashing module can also incorporate educational elements, such as handwashing step diagrams and water-saving tips, to cultivate good personal hygiene habits in children.

[0146] Children's wash areas need to be clearly marked so that children can easily find them.

[0147] The design of children's washroom modules should facilitate daily cleaning and maintenance to ensure the overall hygiene level of the restroom.

[0148] The modular second-size urinal module 15 adjacent to the second-size washroom module, such as... Figure 3 As shown, the second-sized urinal module 15 has a semi-circular plane and includes at least:

[0149] The second-sized urinal, 151, features a sensor-activated flush.

[0150] The second-size urinal module 15 is a urinal designed for children. The size of the second-size urinal 151 in the second-size urinal module 15 is smaller than that of the first-size urinal 121. In other words, the designed children's urinal should be lower in height than the accessible urinal for adults, so that children can use it while standing.

[0151] For example, for shorter children, height-adjustable footrests and handrails 23 can be provided to ensure the safety and comfort of children when using the second-size urinal 151.

[0152] For example, sensor-activated flushing is designed to be easy for children to operate.

[0153] The second-size urinal 151 is connected to the second-size toilet module via the junction wall 21.

[0154] For example, the second-sized toilet module has a chamfered rectangle planar shape, including:

[0155] Second-size toilet 161, nursing table 24, tissue box 20 and trash can;

[0156] Among them, the chamfered rectangle is a quadrilateral with all four corners being arc-shaped.

[0157] Based on actual needs and design standards, the module should be large enough to allow users to move freely and have sufficient space. For example, the space width is 850mm, but the specific dimensions can be adjusted according to actual conditions.

[0158] For example, the second-size toilet 161 is located on the side of the second-size toilet module away from the wheelchair turning space, and is of a moderate height to accommodate the use needs of most adults.

[0159] Nursing station 24 is located next to the toilet.

[0160] For example, the nursing table 24 is typically foldable so that it can be folded away when not in use to save space; and when needed, it can be unfolded into a flat surface for diaper changing, dressing assistance or other nursing activities.

[0161] The tissue box 20 is placed in a location easily accessible to the user, such as on the wall next to the toilet.

[0162] The trash can is located on the side of the toilet, close to the junction wall 21, without obstructing passage. It can be opened by foot pedal for easy use.

[0163] For example, the longest portion of each functional module protruding into the rotation space does not extend into the circumference corresponding to the radius of the rotation space. The aforementioned direction is designated as the first direction, and the direction perpendicular to this direction is designated as the second direction.

[0164] For example, the semi-circular opening of the module faces the center of the wheelchair turning space, that is, it extends along the first direction. Then, the second-sized toilet module can be arranged as follows:

[0165] The second-sized toilet seat 161 is located in the first direction near the junction wall 21, with sufficient space on both sides for installing grab bars 23. A tissue box 20 can be installed on one side of the toilet for easy access. A nursing table 24 is installed on one side of the toilet, adjacent to the installation position of the tissue box 20.

[0166] The first-size toilet module is connected to the second-size toilet module via a partition wall 21.

[0167] The first-sized toilet module 17 has a chamfered rectangle surface and includes at least:

[0168] The first-size toilet seat 171, armrests 23, nursing table 24, tissue box 20, and trash can;

[0169] Among them, the chamfered rectangle is a quadrilateral with all four corners being arc-shaped.

[0170] For example, the first-sized toilet 171 should be large enough, depending on actual needs, to allow wheelchairs to enter and exit freely and have sufficient turning space. For example, it should be at least 1.5 meters wide and at least 2.0 meters long, with the specific dimensions adjustable according to actual circumstances.

[0171] The first-size toilet 171 is located in a position close to the junction wall 21 in a first direction of the first-size toilet module, and for example, the height can be 46 cm or higher.

[0172] For example, a sturdy handrail 23 is provided on each side of the toilet, with a height of 800mm, to facilitate the user's grip.

[0173] The layout of the first-size toilet module is similar to that of the second-size toilet module. However, the space area of ​​the left side module of the first size is larger than that of the left side module of the second size.

[0174] In some possible embodiments, the positions of the functional modules in the above embodiments can be adjusted, as long as each functional module is placed around the circular space of the wheelchair turning space.

[0175] In some embodiments, the components within each module, such as the toilet seat in the first-sized toilet module, are all rounded at the corners to ensure maximum utilization of the internal space. This rounded corner treatment also prevents sharp edges from causing injury to the user, improving safety. Furthermore, the rounded corner design of all edges and corners creates a smooth and natural overall space, facilitating user movement between modules.

[0176] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
