Abstract
Description
Technical Field
[0001] This invention belongs to the field of public health facility technology, and in particular relates to a wetland blowing device with drainage function. Background Technology
[0002] Wet areas generally refer to areas in a building that are prone to water accumulation or high humidity. Wet areas in public places include public restrooms, restaurant kitchens, public bathing areas, and processing workshops that include rinsing. The cleanliness of the floors directly affects the safety, comfort, and workload of on-site personnel.
[0003] Well-known wet areas, such as public restrooms in highway service areas, experience a significant increase in visitors during holidays and peak tourist seasons, becoming densely populated areas. A long-standing problem is the insufficient number of cleaning staff, making it difficult to provide efficient service during peak hours. This leads to deteriorating hygiene conditions, a significant decrease in user comfort, and a substantial increase in the frequency of cleaning and the workload of dedicated staff. The pain points are mainly reflected in the following two aspects:
[0004] In terms of management: the level of dry cleaning and facilities for wet areas in such places are backward. The conventional cleaning method is manual water spraying or wet mopping, followed by one or more floor blowers to blow air onto the wet ground. Cleaning staff need to constantly adjust the angle of the floor blowers to increase the airflow area. The cleaning effect is not timely, the blowers are noisy, and the wiring of the facilities is arbitrarily winding on the ground, which increases the danger to passers-by. Sometimes the air vents are directly facing tourists, which seriously affects their comfort.
[0005] In terms of usage: Although such places, especially the men's restroom urinal area, have signs such as "One small step forward, one giant leap for civilization", the quality of people using the toilet varies, resulting in dirt and stains accumulating on the floor. The floor hygiene of most urinal areas is extremely poor. The reason for this is that the area is not designed in accordance with ergonomic principles and has technical defects. It is difficult to solve the current situation by relying solely on individual self-discipline.
[0006] The adverse effects of the aforementioned pain points also exist in wet areas of public places other than public toilets.
[0007] This document, published in China (CN219411134U) on July 25, 2023, discloses a floor drainage structure for urinals in public restrooms. It includes a drainage trough body installed on the floor of the urinal. The top opening of the drainage trough body has stepped grooves around its perimeter, with drainage grates embedded within these grooves. A drain outlet is located at the bottom of the drainage trough body, which slopes towards the drain outlet. A drain pipe is fixed inside the drain outlet. An inlet is located at the top of the side wall of the drainage trough body, situated on the highest side of the slope. An installation pipe is fixed to the inlet, with its inlet end connected to the drain end of a washbasin in the restroom. This urinal floor drainage structure has a single function, only providing drainage. In densely populated areas, it commonly leads to deterioration of the surrounding sanitation and reduced comfort, requiring frequent cleaning and increasing the workload of dedicated personnel. Summary of the Invention
[0008] The purpose of this invention is to provide a wet area blowing device with drainage function to solve the technical problems of "the pain points of blowing and dehumidifying wet areas in densely populated or wet areas with flushing functions, the deterioration of hygiene and reduced comfort in public wet areas, the need for frequent cleaning, and the increase in the labor intensity of full-time personnel".

Unless otherwise stated, all patents, patent inventions, and publications cited in this document are incorporated herein by reference in their entirety. If multiple definitions exist for terms in this document, the definitions in this chapter shall prevail.
[0010] It should be understood that the above brief description and the following detailed description are exemplary and for illustrative purposes only, and do not limit the subject matter of the invention in any way. In this invention, the singular is used in conjunction with the plural unless otherwise specifically stated. It should also be noted that, unless otherwise stated, the use of “or” or “or” means “and / or”. Furthermore, the use of the term “comprising” and other forms such as “including,” “containing,” and “contains” are not limiting.
[0011] The term "water-facing side" as used in this article refers to the side of the wetland blowing device closest to the water source.
[0012] The term "back side" as used in this article refers to the side of the wetland blowing device that is furthest from the water source.
[0013] A wet area blowing device with drainage function includes a dry chamber component 1 and a wet chamber component 2; the two are arranged side by side to form a double-cavity trench structure 4, the surface of which is covered with a pedal 3; The dry chamber assembly 1 is located on the back side of the pedal 3, and both ends can be connected to the blower. The back side of the dry chamber assembly 1 is provided with a strip-shaped air outlet 12 to guide the air from the blower to the wet area ground for dehumidification. The wet chamber assembly 2 is located on the front side of the pedal 3, and the front side of the wet chamber assembly 2 is provided with a linear channel outlet 22 for collecting wastewater from the wet area ground.
[0014] This invention integrates the functions of drying and draining the ground, greatly improving work efficiency. The device is installed on the wet ground in public places. Its wet chamber component 2 can replace the traditional drainage ditch and collect the ground sewage through the linear ditch opening. Its dry chamber component 1 is connected to the blower and delivers the ground-level "air curtain" through the strip air outlet to efficiently dry the ground moisture.
[0015] Specifically, for example, if the blower is a floor blower, the air outlet and rated power of the floor blower are matched with the structure and design air volume of the air supply channel 11.
[0016] Preferably, the inner cavity of the double-cavity groove structure 4 is arranged with multiple rib-shaped supports, which are composed of window frame type supports 13 and door frame type supports 23 arranged side by side.
[0017] In this technical solution, the ribbed support increases the wall strength of the double-cavity groove structure 4.
[0018] Preferably, the rib-shaped support is a reinforcing skeleton of the inner wall of the double-cavity groove structure 4, and is formed in one piece with the inner wall of the groove.
[0019] In this technical solution, the rib-shaped support is used to support the inner wall of the trench, which is sufficient to withstand the external force of people stepping on it.
[0020] Preferably, the dry chamber assembly 1 includes an air supply channel 11, a strip air outlet 12, and a window frame bracket 13; the strip air outlet 12 is provided on the back side of the top of the air supply channel 11, and the rib-shaped bracket portion in the inner cavity of the air supply channel 11 is a plurality of arranged window frame brackets 13.
[0021] Specifically, the air supply duct 11 has a rectangular cross-section, and the strip air outlet 12 can be a single-slit or multi-slit grille type, with the lower edge of the strip air outlet 12 being higher than the ground.
[0022] In this technical solution, the dry chamber component 1 can initially prevent cleaning wastewater from overflowing from the strip air outlet 12 into the ventilation ditch body 11.
[0023] The window frame support has a four-sided enclosed skeleton when viewed from the front.
[0024] Specifically, the window frame bracket 13 is a frame-shaped skeleton with an outline that matches the inner cavity of the air supply channel 11. The cross-section of the skeleton is T-shaped or I-shaped, and the skeleton protrudes from the inner wall of the air supply channel.
[0025] Preferably, the wet chamber assembly 2 includes a drainage ditch body 21, a linear ditch opening 22, and a door frame type support 23; the linear ditch opening 22 is provided on the water-facing side of the top of the drainage ditch body 21, and the rib-shaped support portion in the inner cavity of the drainage ditch body 21 is a plurality of arranged door frame type supports 23.
[0026] Specifically, the cross-section of the drainage ditch body 21 is a rectangle with a notch at one corner. This notch structure is designed to match the linear ditch opening 22. The linear ditch opening 22 is flush with the ground elevation, and the cleaning wastewater flows into the drainage ditch body 21 from the linear ditch opening 22.
[0027] The frame-like support has a three-sided enclosed skeleton when viewed from the front. The bottom wall of the drainage ditch 21 has no protruding skeleton to avoid creating drainage obstacles and causing sewage retention and mosquito breeding.
[0028] Specifically, the door frame bracket 23 is a frame-shaped skeleton with an outline that matches the inner cavity of the drainage ditch body 21, and the cross-section of the skeleton is T-shaped or I-shaped.
[0029] Preferably, the dry chamber assembly 1 is arranged on the back side of the water surface, and the wet chamber assembly 2 is arranged on the front side of the water surface. The specifications of the two sets of trenches should be calculated according to the usage scenario and the design width of the pedal 3, and then their manufacturing form should be coordinated. The two sets of components can be manufactured separately or as a whole. When manufactured as a whole, they share a cavity wall.
[0030] Preferably, the pedal 3 is covered by a single piece of material on the surface of the double-cavity groove structure 4, and the connection method during manufacturing can be either a split relationship or an integral relationship.
[0031] Specifically, the split connection is a snap-fit movable connection between the pedal 3 and the double-cavity groove structure 4, while the integrated connection is an integral molding of the pedal 3 and the double-cavity groove structure 4. Both connection methods adopt existing technologies, and matching components are provided by professional manufacturers. This invention does not impose any limitations.
[0032] Preferably, the width range of the treadle 3 is composed of the width range between the backwater edge 31 and the frontwater edge 32; The backwater edge 31 has a downward-curving arc-shaped structure that protrudes beyond the side wall of the air supply ditch 11. The outer side of the water-facing edge 32 is a notch structure at the top of the drainage ditch body 21. This notch structure is designed to be matched with the linear ditch opening 22 for installing the linear ditch opening 22.
[0033] In this technical solution, the detailed design of the downward-curving arc structure of the backwater edge 31 of the pedal 3 forms a slow transition with the ground height difference, which has the function of preventing tripping.
[0034] Preferably, the arc-shaped back surface edge 31 is uniformly provided with arc-shaped supports 34 extending outward from the rib-shaped support position to strengthen the arc wall strength of the back surface edge 31.
[0035] Preferably, the surface of the pedal 3 is uniformly covered with raised patterns or other anti-slip structures to ensure safety.
[0036] The distance between the outermost end of the downward-curving arc structure of the backwater edge 31 of the pedal 3 and the ground is the same as the width of the strip-shaped air vent 12.
[0037] In this technical solution, the structural design is conducive to forming a ground-level "air curtain" with uniform and gentle airflow, avoiding discomfort to the legs and feet of passersby.
[0038] Preferably, when the treadle 3 is an inclined surface, one side of its backwater edge 31 is higher than the ground, and its frontwater edge 32 is turned into a horizontal surface when there is zero height difference with the ground. The width range of this horizontal surface is equal to the width range of the notch structure. The notch structure is used to install the linear groove 22. Alternatively, when the treadle 3 is horizontal, both its backwater edge 31 and frontwater edge 32 are higher than the ground. The frontwater edge 32 is bent downwards with rounded corners, and its outer side forms the notch structure for installing the linear ditch opening 22 with the side wall of the drainage ditch body 21.
[0039] Preferably, when the pedal 3 and the double-cavity groove structure 4 are integrally manufactured, all components and their parts are made of hot-dip anti-corrosion steel, stainless steel or high-strength aluminum alloy. Alternatively, when the pedal 3 and the double-cavity groove structure 4 are manufactured separately, the lower surface of the pedal 3 is still uniformly arranged with rib-shaped supports to increase the strength of the plate wall. The material of the double-cavity groove structure 4 can be changed to a precast resin concrete component. The preparation of this precast component is based on existing technology and its structural outline specifications will not be detailed here. The rib-shaped supports in its groove cavity are no longer required to meet the strength requirements of the main body.
[0040] Compared with the prior art, the present invention has at least the following six beneficial effects: 1. Combines drying and drainage functions: This device is installed on the wet ground in public places. Its wet chamber component can replace the traditional open drainage ditch and collect ground sewage through the linear ditch opening. Its dry chamber component is connected to the blower and delivers a ground-level "air curtain" through the strip air outlet to efficiently dry the ground moisture. Without changing the position of the original traditional drainage ditch in the room, this invention integrates the functions of drying and draining the ground, and has the functions of collecting wet wastewater and drying the ground, which greatly improves the efficiency of operation.
[0041] 2. Safe and efficient: The device greatly reduces the labor intensity and cleaning frequency of cleaning staff, avoids physical collisions with passersby while they are working, and avoids overlapping of different jobs, thus significantly improving personal safety and work efficiency.
[0042] Compared with traditional mobile floor blowers, the linear trench outlet, with its ground-level air outlet method, significantly improves airflow strength, air outlet angle, drying area, work continuity, and personnel comfort.
[0043] 3. Wide range of applications: The technology of this invention is easy to transform and implement, and is suitable for a wide range of applications. It can be applied to the floors of public restrooms (urinals, handwashing areas), catering kitchens (preliminary processing areas, stove operation areas), bathhouses (bathrooms, shower areas), or processing workshops (rinsing areas).
[0044] 4. Hygienic and practical: This invention is designed and used in accordance with the principles of ergonomics. It can simultaneously meet the functional requirements of drying wet areas and collecting sewage in public places, improve work efficiency, ensure personal safety, significantly improve the safety and cleanliness of wet areas in densely populated places, and greatly reduce the frequency of cleaning and the labor intensity of full-time personnel. Especially when used in public restrooms, the distance between the drainage ditch and the urinal and the slope of its surface are in accordance with ergonomic principles. People must stand on the inclined footboard to use the toilet in a comfortable posture, which ensures the hygiene of the wall base of the urinal. Even if there are spilled stains and cleaning wastewater on the ground, they will be smoothly collected and discharged from the linear ditch, greatly improving the hygiene of the wet area environment. The maximum spacing of the rib-shaped brackets matches the standard spacing of the urinals, and their arrangement corresponds to the urinal partition, serving as a support unit. An additional rib-shaped bracket can be added in the middle of this unit to increase the strength of the plate, prevent disturbance when people step on it, and increase foot comfort and the durability of the pedal.
[0045] 5. Neat and aesthetically pleasing: This device is simple in structure, easy to prepare, and convenient to use. It can be integrated with the floor decoration and has the characteristics of being aesthetically pleasing and high-end.
[0046] The strip-shaped air vent is an extremely narrow strip, and the linear trough opening is an extremely narrow linear opening, which is more aesthetically pleasing than the traditional drainage grate that is the same width as the trough body. The blower that supplies air to the air supply duct can be placed in the corner or at the base of the wall. Even if there are exposed wires, they will not be stretched on the ground where people walk, avoiding the mess on the wet ground and keeping the environment clean.
[0047] 6. Convenient maintenance: Compared with traditional processes, the preparation and construction of the device do not require special conditions or technical skills, and there is no difficulty in installation and use; the pedestal split design makes disassembly more convenient, and it is suitable for public kitchens or processing workshops with rinsing functions, making operation more convenient in the cleaning and maintenance process.

[0054] Combination Figures 1-4 As shown, this invention provides a wet area dehumidification device with drainage function, comprising: a dry chamber assembly 1 and a wet chamber assembly 2; the two are arranged side by side to form a double-cavity channel structure 4, the surface of which is covered by a foot pedal 3. The dry chamber assembly 1 is located on the back side of the foot pedal 3, and both ends can be connected to a blower. A strip-shaped air outlet 12 is provided on its back side to guide the air from the blower to the ground for dehumidification. The wet chamber assembly 2 is located on the front side of the foot pedal 3, and a linear channel outlet 22 is provided on the front side of the foot pedal 3 for collecting wastewater from the wet area ground 7. The double-cavity channel structure 4 has rib-shaped supports arranged inside to increase the strength of the cavity walls.
[0055] This wet area blowing device is installed on the wet area ground in public places. Its wet chamber component 2 can replace the traditional drainage ditch and collects the ground sewage through the linear ditch outlet 22. Its dry chamber component 1 is connected to the blower and delivers the ground-level "air curtain" through the strip air outlet 12 to efficiently dry the ground moisture. This invention integrates the functions of drying and draining the ground, which greatly improves the work efficiency.
[0056] Preferably, the blower is an existing product, and preferably a floor blower whose air outlet and rated power are matched with the trench structure and its designed air volume. It can also work in conjunction with an intelligent system to achieve energy saving and consumption reduction. Both the equipment and the system are existing mature products and technologies, and this invention does not impose any restrictions.
[0057] The dual-cavity channel structure 4 has one part below ground level with a height of H1, and another part above ground level with a height of H2; the total height H = H1 + H2. The inner cavity width of the air supply channel 11 is w1, and the inner cavity width of the drainage channel 21 is w2. The wall thickness between them is d. Therefore, the total inner cavity width of the dual-cavity channel structure 4 is Wb = w1 + d + w2; the height of the inner cavity below ground level is h. The total width of the dual-cavity channel structure 4 is W = d + Wb + d.
[0058] Preferably, the dry chamber assembly 1 includes an air supply channel 11, a strip air outlet 12, and a window frame bracket 13; the strip air outlet 12 is provided on the back side of the top of the air supply channel 11, and multiple window frame brackets 13 are arranged in the inner cavity of the air supply channel 11.
[0059] The cross-section of the air supply trough 11 is rectangular. The width and height of the inner cavity below the ground of the air supply trough 11 are w1 x h, and the dimensions of w1 and h are both in the range of 110mm-300mm. The width of the strip air outlet 12 is h2, and the range of h2 is 10mm-18mm. The strip air outlet 12 can be a single-slit or multi-slit grille type. The lower edge of the strip air outlet 12 is higher than the ground by h1, and the range of h1 is 4mm-10mm. It has a water-repellent function to initially prevent cleaning wastewater from overflowing from the strip air outlet 12 into the air supply trough 11.
[0060] The window frame bracket 13 has a four-sided enclosed skeleton shape when viewed from the front.
[0061] Specifically, the window frame bracket 13 is a frame-shaped skeleton with a spacing of 400mm-800mm. Its outline matches the inner cavity of the air supply channel 11. The cross-section of the skeleton is T-shaped or I-shaped. The height of the skeleton protruding from the inner wall of the air supply channel is h3, with h3 ranging from 5mm to 15mm.
[0062] Preferably, the wet chamber assembly 2 includes a drainage ditch body 21, a linear ditch opening 22, and a door frame type bracket 23; the linear ditch opening 22 is provided on the water-facing side of the top of the drainage ditch body 21, and multiple door frame type brackets 23 are arranged in the inner cavity of the drainage ditch body 21.
[0063] Specifically, the cross-section of the drainage ditch 21 is a rectangle with a notch at one corner. The internal dimensions of the drainage ditch 21 below ground level are w2 x h, where w2 is 150mm-300mm and h is 110mm-300mm. The width of the linear ditch opening 22 is W4 and the height is H3. Depending on the wet area scenario, a single slit width of 10mm-15mm is used for areas with lower water collection requirements, while a single slit width of 20mm or a multi-slit structure such as double or triple slits with a width greater than 20mm is used for areas with higher water collection requirements to increase drainage collection speed. However, it needs to be used in conjunction with anti-jamming components such as grates. The linear ditch opening 22 is flush with the ground elevation. Cleaning wastewater flows into the drainage ditch 21 from the linear ditch opening 22 and is then discharged.
[0064] The portal frame supports 23 are all frame-shaped skeletons, arranged at intervals of 400mm-800mm. Their outlines match the inner cavity of the drainage ditch body 21. The cross-section of the skeleton is T-shaped or I-shaped, and the height of the skeleton protruding from the inner wall is h3, ranging from 5mm to 15mm. The front view of the portal frame supports 23 is a three-sided enclosed skeleton, meaning that there is no skeleton protruding from the bottom wall of the drainage ditch body 21, to prevent the formation of obstacles at the bottom of the ditch that could cause sewage retention and mosquito breeding.
[0065] Preferably, the dry chamber assembly 1 is arranged on the back side of the water surface, and the wet chamber assembly 2 is arranged on the front side of the water surface. The specifications of the two sets of trenches should be calculated according to the usage scenario, and the cross-sectional dimensions of each set should be calculated separately, as well as the design width Wa of the matching pedal 3. Then, the manufacturing form should be coordinated and designed. The two sets of trenches can be manufactured separately or as a single unit. When manufactured as a single unit, they share a cavity wall, which makes the structure more integral and strong.
[0066] Preferably, the pedal 3 is covered on the surface of the double-cavity groove structure 4 by a single piece of plate, and the connection method during manufacturing can be either a split relationship or an integral relationship; Specifically, the split connection is a snap-fit movable connection between the pedal 3 and the double-cavity groove structure 4, while the integrated connection is an integral molding of the pedal 3 and the double-cavity groove structure 4. Both connection methods adopt existing technologies, with matching components and manufacturing processes provided by professional manufacturers, and this invention does not impose any limitations.
[0067] Specifically, the width of the pedal 3 is Wa, ranging from 280mm to 350mm. This width is composed of the backwater edge 31 and the frontwater edge 32 and the width between them. The backwater edge 32 has a downwardly curved arc structure, protruding beyond the side wall of the air supply ditch 11 by a width of W3, ranging from 10mm to 20mm. The outer side of the frontwater edge 32 is a notch structure at the top of the drainage ditch 21, with a width of W4, ranging from 10mm to 50mm. This notch structure is designed to match the linear ditch opening 22 for installation.
[0068] The width of the air supply ditch 11 is W1, the width of the drainage ditch 21 is W2+W4, and the wall thickness between them is d. Then the width of the tread plate 3 Wa = W3+W1+d+W2, excluding the width W4 of the linear ditch opening 22.
[0069] Preferably, the back side of the back surface edge 31 is uniformly provided with an arc-shaped support 34 extending outward from the position of the rib-shaped support to strengthen the arc wall. The cross section of the arc-shaped support 34 protrudes 5mm from the arc wall.
[0070] Meanwhile, the detailed design of the downward-curving arc structure of the backwater edge 31 of the pedal 3 creates a gradual transition with the ground level, thus preventing tripping.
[0071] Preferably, the surface of the pedal 3 is uniformly provided with anti-slip textures 33 or other anti-slip structural measures to ensure safety.
[0072] The outermost end of the downward-curving arc structure of the backwater edge 31 of the pedal 3 is 10mm-18mm away from the ground, and is the same width as the strip air outlet 12 to ensure that the air volume and wind speed do not change.
[0073] Preferably, when the treadle 3 is an inclined surface, the height difference between one side of its back water surface edge 31 and the ground is H2, and the height difference between H2 and the ground is 15mm-25mm. When its front water surface edge 32 is zero height difference from the ground, it becomes a horizontal surface. The width range of this horizontal surface is equal to the width range of the notch structure, which is used to install the linear groove 22. Alternatively, when the treadle 3 is horizontal, the height difference between the back water edge 31 and the front water edge 32 above the ground is H2, with H2 ranging from 15mm to 25mm. At this time, the front water edge 32 is bent downwards with rounded corners, and its outer side forms the notch structure with the side wall of the drainage ditch, which is used to install the linear ditch opening 22.
[0074] Preferably, when the pedal 3 and the double-cavity groove structure 4 are integrally manufactured, all components and their parts are made of hot-dip anti-corrosion steel, stainless steel or high-strength aluminum alloy, and the wall thickness must be professionally calculated. The wall thickness of the pedal 3 and the rib-shaped bracket is d, and d should not be less than 3.0 mm. When the pedal 3 and the double-cavity groove structure 4 are prepared separately, the lower surface of the pedal 3 is still uniformly arranged with rib-shaped supports to increase the strength of the plate wall. The material of the double-cavity groove structure 4 can be changed to a precast resin concrete component. The preparation of this precast component is based on existing technology and the specifications of its structural outline will not be detailed. The rib-shaped supports in its groove cavity are no longer required to meet the strength requirements of the main body. The lengths of the pedal 3 and the double-cavity groove structure 4 can be standardized in sections or cut as needed, with a general length range of 1.0-3.0 meters for easy on-site assembly; when used in wet urinal areas, a length of 0.8-2.4 meters is preferred to facilitate matching with the spacing of the partition 6 of the urinal 5. The joints of the segmented grooves have airtight and leak-proof construction measures.
[0075] Example The following example, using public restrooms in highway service areas as an illustration, further explains the implementation concept of this invention in conjunction with the structural diagram provided by this invention: This embodiment provides a wet-area blowing device for the urinal area of a men's restroom in a highway service area, specifically as follows: Figure 1 As shown, the urinals 5 are spaced 800mm apart, and the partitions 6 are also spaced 800mm apart.
[0076] I. Preparation of wetland evaporation device: 1. All materials are made of high-strength aluminum alloy, including: 1.1 Dual-cavity groove structure, wall thickness 2.0 mm; 1.2 The ribbed scaffold structure has a wall thickness of 3.0 mm, and the ribs of the scaffold protrude into the double-cavity groove structure 4. The width of the inner cavity is h3 = 10 mm. 1.3 The pedal 3 adopts an inclined surface with a wall thickness d = 3.0mm and a total surface width Wa = 300mm. The total width Wa includes the width W3 = 15mm of the outward protruding side wall of the arc-shaped structure that bends downward on the back surface 31 of the pedal, but does not include the width W4 = 15mm of the single-slit component of the drainage ditch 21 at the front surface 32 of the pedal. The upper surface of the pedal is provided with a wavy anti-slip texture 34 along its transverse direction. 2. A dual-cavity structure scheme is fabricated by integrating dry chamber component 1 and wet chamber component 2, wherein: 2.1 The cross-sectional dimensions of the air supply duct 11 of the dry chamber component 1, below the ground, are designed as w1 xh = 110mm × 200mm according to the size of the urination area; 2.2 A strip-shaped air vent 12 is installed on the back side of the dry chamber component 1, with a height h2 = 15mm. The lower edge of the strip-shaped air vent 12 is 5mm above the ground, serving as a water-repellent sill. 2.3 The cross-sectional dimensions of the drainage ditch body 21 of the wet chamber component are designed below ground level as w2 xh = 175mm × 200mm based on the size of the urination area. At this time, the h value is only a reference value for the preparation scheme. It needs to be combined with the linear ditch design. A notch structure with a width of W4 = 15mm is cut off at the upper corner of the water-facing side. The height H3 of the notch structure matches the linear ditch 22 of the existing product. 2.4 The notch structure is flush with the ground and a single-slit drainage ditch 21 is provided to collect sewage generated from the direction of the urinal 5; 2.5 The two grooves are equipped with matching rib-shaped supports arranged evenly along the longitudinal direction, with a spacing of D = 400mm. The pedal 3 between every 3 rib-shaped supports serves as a support unit.
[0077] II. Installation of wet area blowing device: This device is constructed in accordance with ergonomic principles and widely recognized and followed comfort requirements. The specific process is as follows: 1. The water-facing edge 32 of the pedal faces the wall of the urination area and is parallel to it. The distance between the drainage ditch 21 and the wall is 40 cm to 50 cm. The ground in this area slopes from the base of the wall to the ditch opening, with a maximum slope of 2%. The lowest point of the ground is flush with the surface of the ditch opening. 2. The rib-shaped bracket at the center of each support unit is aligned with the urinal. This arrangement provides optimal strength support, prevents the pedal from deforming due to high-frequency stepping, and ensures sturdiness and durability. 3. The height difference H2 between the back water surface edge 31 of the pedal 3 and the ground is 20mm. The ground outside the strip air vent 12 slopes from the root of the air vent away from it, with a slope of not less than 1%, so as to prevent sewage from flowing into the air supply ditch 11. Even if it occasionally overflows, it can be easily dried by the blower. 4. The length of the pedal 3 and the double-cavity groove structure 4 can be standardized in sections or cut as needed. The length is generally 0.8 meters to 2.4 meters. The segment length of the pedal can be a multiple of the groove segment to ensure the overall appearance as much as possible. The joints of the segmented grooves have process measures that match the airtightness and anti-leakage structure. These are all existing technologies and will not be described in detail.
[0078] III. Use of wetland evacuation equipment: 1. Both ends of the air supply trough 11 can be connected to a blower. The ground-level "air curtain" conveyed by the drying chamber component 1 can efficiently dry the ground moisture. The blower can be combined with an intelligent system to perform frequency conversion or complete automatic start and stop, saving energy and reducing consumption. 2. The width of the pedal is suitable for most people's foot size, and the distance between the toes and the sanitary ware can be adjusted according to one's own conditions. When a person faces the urinal and steps on the inclined surface, the body naturally maintains a slightly forward-leaning posture, which will not cause the body or clothes to touch the sanitary ware, nor will it cause serious liquid splashing or urine leakage on the ground. 3. The height difference between one side of the backwater edge 31 of the pedal and the ground is in accordance with the norm. The backwater edge 31 has a downward curved arc structure and an outward protruding arc structure to meet the ergonomic comfort. The detailed design will not cause the feet to trip, and it plays a ground-level guiding role in the direction of air outlet, improving the working area and drying efficiency.
