[0001] The present invention relates to a Western-style toilet, and more specifically, to a Western-style toilet with a foot health manager.

Background Art

[0002] A Western-style toilet, which is also called a Western-style toilet or a sitting toilet, is used for defecation while sitting on a chair. It is one of the necessities with a very high usage frequency and plays an important role in daily life.

[0003] The Western-style toilet is in a sitting form and is mainly placed in the bathroom in the home. Therefore, it is used for rest and cleaning even when not defecating. However, until now, there has been no example of a commercialized additional function other than functions related to defecation such as local cleaning.

[0004] On the other hand, an important and frequent behavior in the bathroom in daily life is foot washing.

[0005] The feet secrete more than three times as much sweat as other body parts and have almost no sebaceous glands, so they are prone to drying and roughness. If the feet are not properly managed, there is also a risk of various foot diseases such as athlete's foot.

[0006] Especially when epidemic viruses are prevalent or air pollution is serious due to fine dust or the like these days, it is only possible to protect health by always keeping the feet clean after going out.

[0007] Generally, when washing the feet, one bends the waist so that the hand can reach the feet and washes every corner of the feet with the hand. However, patients with lumbar disc herniation, pregnant women, or the elderly and the weak who have difficulty maintaining body balance have great difficulty washing their feet by themselves because their movements are restricted, and they are not free in terms of safety issues such as slipping.

[0008] Therefore, conventional foot-washing products were sometimes placed around the toilet bowl, which also served as a chair, or attached to the toilet bowl itself, to allow users to wash their feet safely. However, these products were plagued by various unnecessary problems, including wastewater treatment, and the truth is that they are still far from being truly effective.

[0009] For example, a typical Western-style toilet bowl is designed to be tightly fitted to the bottom surface, sealing the installation area to block odors. Therefore, when attaching foot washing products to a Western-style toilet bowl, there was a problem in that it was difficult to install wastewater piping. [Overview of the project] [Problems that the invention aims to solve]

[0010] The present invention was made to solve the aforementioned problems, and aims to provide a Western-style toilet in which a foot health management device can be used even in a narrow space by attaching the foot health management device to a storage compartment located at the front lower part of the main body using a sliding structure. In particular, the present invention aims to provide a Western-style toilet that allows users to safely wash and bathe their feet by configuring the toilet seat cover to be used as a chair, while also offering convenience and practicality. The problems that this invention aims to solve are not limited to those mentioned above, and any other problems not mentioned herein will be clearly understood by those skilled in the art from the following description. [Means for solving the problem]

[0011] A Western-style toilet according to one embodiment of the present invention includes a storage section having a storage space at the front lower end for storing a foot health management device, a main body including a toilet water tank and wastewater piping formed extending from the upper end to the rear lower end, and a foot health management device having an inner space for the user's feet to rest and a foot washing water tank with a wastewater outlet formed at the lower end.

[0012] At this time, the Western-style toilet operates such that the foot health management device slides forward from the storage compartment of the main body, opening the inner space of the foot washing basin where the user's feet are placed, and slides backward, storing the foot health management device back into the main body.

[0013] The storage section of the main unit is equipped with a sliding rail on the sliding movement section of the foot-washing tub, and the foot-washing tub can be equipped with casters on a portion of its upper and lower ends so that it can move along the sliding rail.

[0014] At both ends of the storage compartment of the main unit, outer walls are formed to airtightly protect the sliding section of the foot-washing basin and support the front of the main unit. In addition, an inner wall is placed inside the storage compartment, and the space between the lower end of the inner wall and the toilet floor is sealed to prevent foul odors from entering from the wastewater outlet on the toilet floor. The main unit may also be further equipped with a shock-absorbing part at the part that comes into contact with the rear end of the foot-washing basin.

[0015] The main unit's storage compartment has a storage space that is shaped and sized to accommodate a foot-washing basin.

[0016] The foot health management device includes a spray unit, a washing water supply unit, and a user input unit.

[0017] The spray unit sprays a predetermined amount of cleaning water into the inner space of the foot-washing tub.

[0018] The cleaning water supply unit supplies cleaning water to the spray unit.

[0019] The user input unit is located outside the foot-washing tub and displays the operating status of the foot health management device, providing buttons for various functions.

[0020] The foot health management device must use the wastewater piping of a Western-style toilet or another sewer line to discharge the wastewater from the foot washing basin. For this purpose, it may further include a wastewater discharge section located between the outlet and the wastewater outlet on the toilet floor.

[0021] In this case, the wastewater outlet on the toilet floor may be a wastewater outlet for a Western-style toilet that handles wastewater from the toilet bowl, or a wastewater outlet for sewage treatment that handles sewage. However, generally, since there is only a wastewater outlet for a Western-style toilet on the toilet floor in the space below the toilet bowl, it is more preferable to discharge the wastewater to the wastewater outlet of the Western-style toilet. On the other hand, the wastewater discharge section may be formed in a form that is a modified version of the wastewater piping of the main body.

[0022] The foot washing basin of the foot health management device according to the present invention can be manufactured in a way that allows for variable deformation of the inner wall or adjustment of the height, in order to avoid the spatial constraints that arise from the downward tilting of the lower end of the toilet basin of the main body.

[0023] In structures where the inner wall is variably deformable, it is preferable to construct the entire inner wall from a highly elastic material, but other methods are also possible considering durability.

[0024] In this case, the inner wall of the foot-washing tub is composed of a fixed wall and a variable wall, and a connecting part that connects the fixed wall and the variable wall and seals the connection point to prevent water leakage.

[0025] The fixed wall is molded together with the foot-washing basin and has a space in the center where the variable wall is located. The connecting part is used when the variable wall and the fixed wall are joined, and three sides of the variable wall, excluding the upper end, are joined to the fixed wall using the connecting part. Therefore, when the variable wall and the fixed wall are joined using the connecting part, the wall is maintained in a rectangular shape in plan view. However, when the foot-washing basin is located in the storage area of ​​the main body, the variable wall folds inward into the foot-washing basin along the shape of the lower end of the toilet basin of the main body, so the connecting part must be able to deform to reflect this. Therefore, it is preferable that the parts connecting the left and right sides of the variable wall are elastically deformable, and the parts connecting the lower part of the variable wall are configured to be foldable.

[0026] In the case of a method for variably adjusting the height of the inner wall of the foot washing tank, when inserted into the main body, the height must be adjusted to be low so as not to be caught by the lower end of the toilet tank. When the foot washing tank is positioned in front of the main body for the user to use the foot health manager, the height must be adjusted to be high.

[0027] The foot washing tank of the foot health manager is further configured to include a toe washing part for washing between the user's toes in the inner space.

[0028] The toe washing part includes a toe injection nozzle for injecting washing water toward between the user's toes, and a washing member attached to the outside of the toe injection nozzle for removing contaminants sandwiched between the user's toes.

[0029] The injection part includes one or more side injection nozzles arranged on the inner circumferential surface of the foot washing tank for injecting water sideways, and an upward injection nozzle provided at the bottom of the foot washing tank for injecting water upward. At this time, the side injection nozzle is characterized in that the nozzle arranged at the front end part is arranged higher than the nozzle arranged at the rear end part.

[0030] The injection part can further include a downward injection nozzle for injecting water toward the inner bottom of the foot washing tank, a cleaning liquid nozzle arranged inside the foot washing tank for injecting cleaning liquid, and an injection valve connected between the downward injection nozzle and the cleaning liquid nozzle for selectively adjusting the injection of the downward injection nozzle and the cleaning liquid nozzle.

[0031] The foot health manager can further include a control part connected to the user input part for controlling the injection part and the toe washing part.

[0032] Here, the control part preferably controls at least one of the injection pressure, injection method, and injection angle of the injection part.

[0033] The foot health manager can further include a heel washing part rotatably provided at the inner rear end part of the foot washing tank for washing the user's heel.

[0034] The heel cleaning section is positioned to have a predetermined incline that conforms to the shape of the heel.

[0035] The heel washing section may include a rotating member having a structure that is rotatable and connected in the width direction or longitudinal direction to the inner rear end of the foot washing tub, a detachable brush having a rough outer surface that surrounds the rotating member, and a drive unit that rotates the rotating member via a control unit. [Effects of the Invention]

[0036] The Western-style toilet with a foot health management device according to the present invention solves the problem of spatial constraints by attaching the foot health management device to a storage compartment located at the front lower part using a sliding structure. Furthermore, the user can comfortably wash their toes in the foot washing basin of the foot health management device attached to the Western-style toilet, and the wastewater from the foot washing basin can be discharged into the wastewater outlet on the toilet floor without introducing any odor. Therefore, the foot health management device attached to the Western-style toilet according to the present invention allows users to thoroughly wash their feet, including between their toes, while conveniently disposing of wastewater without worrying about the influx of unpleasant odors, enabling foot washing and foot bathing in a very comfortable environment. Furthermore, the present invention can provide convenience and practicality by configuring the toilet seat cover so that the user can use it as a chair. In addition, the foot health management device attached to the inside of a Western-style toilet, which is the present invention, has a structure that allows the soles of the feet and between the toes to be thoroughly washed without bending over or using hands, making it easy for people with physical disabilities or limited mobility to wash and bathe their feet.

[Modes for carrying out the invention]

[0038] The advantages and features of the present invention, and the methods for achieving them, will become clearer with reference to the examples described below in detail, along with the accompanying drawings. However, the present invention is not limited to the examples disclosed below, and can be realized in a variety of different forms. These examples are provided merely to complete the disclosure of the present invention and to fully inform those who are ordinary skill in the art to which the present invention pertains, and the present invention is defined by the claims. On the other hand, the terms used herein are for illustrative purposes of the examples and are not intended to limit the present invention. In this specification, the singular form includes the plural form unless otherwise specified in the text. The terms “comprises” or “comprising” as used in the specification do not exclude the presence or addition of one or more other components, stages, operations and / or elements other than those mentioned.

[0039] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. Since the basic structure of the Western-style toilet according to the present invention is that of a normal Western-style toilet, for the sake of clarity and ease of explanation, a description of the structure of the Western-style toilet itself, which is already known, will be omitted. Instead, the foot health management device attached to the Western-style toilet, and the structure and operation of the foot health management device attached to the Western-style toilet, will be described and illustrated in detail.

[0040] Figure 1 is a schematic diagram showing a Western-style toilet with a foot health management device according to one embodiment of the present invention, and Figure 2 is a diagram showing an example of the operation of a Western-style toilet with a foot health management device according to one embodiment of the present invention.

[0041] As shown in Figures 1 and 2, a Western-style toilet 10 according to one embodiment of the present invention has a structure in which a foot health management device 100 is attached in a sliding manner. In this case, the main body 200 that forms the frame of the Western-style toilet 10 has a toilet water tank (not shown) formed from the front upper end to the rear lower end, and a wastewater pipe (not shown) for the Western-style toilet is provided at the lower end.

[0042] A storage compartment 210 is formed at the lower front of the main body 200. The storage compartment 210 is a storage space capable of housing the foot health management device 100, and has a shape and size that corresponds to the foot washing tub 110 of the foot health management device 100. The foot washing tub 110 of the foot health management device 100 has a structure that allows it to be moved from the storage compartment 210 of the main body 200 by sliding.

[0043] For example, the connection points between the upper and lower ends of the foot-washing tub 110 and the interior of the main body 200 are provided with sliding rails (not shown) and casters (not shown) that can move on the sliding rails. The sliding rails should be of a length only long enough to allow movement on the front and rear surfaces of the foot-washing tub 110 for stable sliding movement of the foot-washing tub 110. Stoppers (not shown) may be provided on the sliding rails at unit lengths to allow the foot-washing tub 110 to stop stably.

[0044] The foot-washing tub 110 may have a structure that allows it to slide electrically via an electric linear actuator (not shown) provided within the main body 200, and it goes without saying that in other embodiments, it may have a structure that allows it to slide manually.

[0045] As another example, an elastic member such as a spring (not shown) is connected to the upper and lower ends of the foot-washing basin 110 and the inside of the main body 200, allowing the user to manually open and close the foot-washing basin 110 from the main body 200 with little effort, much like opening a drawer.

[0046] At this time, the foot-washing tub 110 is structured to return to its initial position by an elastic member, but when a user washes or bathes their feet, the foot-washing tub 110 must be fixed in that position.

[0047] In this case, stoppers placed at intervals of the sliding rail can fix the foot-washing tub 110 in place. For example, fixing holes (not shown) are formed at intervals of the sliding rail, which are located at both ends of the upper and lower ends of the main body 200, and the stoppers have a structure that penetrates the left and right sides of the sliding rail, with the fixing holes in between.

[0048] Outer walls 211 are positioned at both ends of the storage section 210 of the main body 200 to airtightly protect the sliding section of the foot-washing tub 110 and to support the main body 200. The outer walls 211 may be integrated with the main body 200 when positioned outside the foot-washing tub 110, or they may be separate.

[0049] Here, the outer wall 211 surrounds both ends of the foot-washing basin 110 and supports the front end of the main body 200 at its base, distributing the load on the front end of the main body 200 when a user sits on the Western-style toilet 10. This prevents the outer wall 211 from being damaged by the load applied to the front end of the Western-style toilet 10. Furthermore, the main body 200 has an inner wall 220 placed inside the storage section 210, and the space between the lower end and the toilet floor is sealed with another finishing material (e.g., silicone, concrete, etc.), providing a shielding structure that can block odors flowing in from the sewage pipes and sewage outlet.

[0050] If the foot washing tub 110 of the foot health management device 100 repeatedly slides out of the storage compartment 210 of the main body 200, impact may be applied to the contact area, potentially causing wear on that area. Therefore, the main body 200 may be equipped with a shock-absorbing part (not shown) at the part that contacts the rear end of the foot washing tub 110 to mitigate impact.

[0051] Although the Western-style toilet cover 400 appears similar to existing covers in the drawings, in order to provide convenience for the user when using the foot health management device 100, the Western-style toilet cover 400 of the present invention rotates on a pivot axis (not shown) and is in the form of a chair having a backrest (not shown).

[0052] For example, the Western-style toilet seat cover 400 has a double-layered structure, with the lower layer being a basic seat (not shown) on which the user can sit, and the remaining upper layer being a backrest.

[0053] In this case, the basic seat may be provided with a recessed seat groove (not shown) in the section where the user sits. When the backrest overlaps the basic seat, the backrest has a shape and size that corresponds to the seat groove.

[0054] In other words, when the backrest is inserted into the seat groove, it is maintained in a horizontal position, and when it is removed from the seat groove and rotated by a radius of approximately 90 degrees, it is maintained in a vertical position that rests against the user's back. The rotational movement between the backrest and the base seat is performed either manually by the user or automatically by a separate button (not shown).

[0055] A waterproof cushion (not shown) is placed between the backrest and the seat groove. Such a cushion is a replaceable type that can be selectively attached and removed between the backrest and the seat groove.

[0056] On the other hand, the foot health management device 100 includes a foot washing water tank 110, a spray unit 120, a user input unit 130, and a control unit 140.

[0057] The foot washing tub 110 can hermetically house an electronic circuit board capable of driving the foot health management device 100 and related components, and also includes various cables, sensors, actuators, switches, LEDs, and other components connected to it.

[0058] The foot-washing basin 110 basically has a space inside where the user's feet can be placed, and its top surface is open. As mentioned above, such a foot-washing basin 110 is structured to be insertable into the storage section 210 of the main body 200, and can be opened and closed by sliding from one open side of the main body 200 to the front and rear sides of the Western-style toilet 10.

[0059] The spray unit 120 sprays a predetermined amount of cleaning water into the inner space of the foot-washing tub 110.

[0060] The user input unit 130 is located outside the foot-washing tub 110 or on the foot-washing tub cover 112, and displays the operating status of the device and provides buttons for various functions. The user input unit 130 can be pre-configured in various ways.

[0061] The control unit 140 is a single configuration that can control the entire device in an integrated manner, and when the user input unit 130 presses a button for a function in accordance with the user's operation command, it controls the operation of the device corresponding to that function.

[0062] Figure 3 is a schematic diagram illustrating one example of a modified operation of a Western-style toilet with a foot health management device according to one embodiment of the present invention.

[0063] Referring to Figure 3, the foot health management device 100 is stored in a sliding manner from the storage section 210' of the main body 200' of the Western-style toilet 10, which is the same structure as the method described in Figure 2, but its form is slightly different.

[0064] The storage section 210' of the main body 200' has a relatively smaller cross-sectional area compared to the storage section 210 of the main body 200 in Figure 2. By reducing the area of ​​the storage section 210', the main body 200' can secure even more space for installing the wastewater piping of the Western-style toilet.

[0065] The foot-washing basin 110' is U-shaped, and the storage section 210' is sized and shaped to correspond to the foot-washing basin 110'. In this configuration, the foot-washing basin 110' can be used as a space for washing both of the user's feet simultaneously, and its structure may be modified to allow for separate washing of each foot via a partition (not shown) that selectively divides the space.

[0066] On the other hand, the variable wall 114' that forms the inner wall of the foot-washing basin 110' has a structure that corresponds to the shape of the lower end 212' of the toilet basin located at the front of the main body 200', thereby allowing the foot-washing basin 110' to be inserted so that it fits snugly into the storage section 210'.

[0067] Figures 4 and 5 are schematic side views showing the joint structure of the foot-washing basin, along the A-A' cross-section shown in Figure 3. Unlike Figure 3, Figures 4 and 5 show an embodiment using a foot-washing basin that is taller and allows both feet to be placed together.

[0068] As shown in Figures 4 and 5, the foot washing basin 110' of the foot health management device 100 is slidably coupled to the front of the main body 200' of the Western-style toilet 10.

[0069] At this time, the toilet water tank formed at the upper end and rear lower end of the main body 200' has its lower end 212' affecting the height of the foot washing water tank 110'.

[0070] If the height of the foot-washing basin 110' is low, the lower end 212' of the toilet basin and the foot-washing basin 110' do not affect each other. However, if the foot-washing basin 110' needs to be raised (for example, in the case of a siphon-type toilet, where the toilet basin is tilted downwards and the foot-washing basin needs to be raised), problems may arise. That is, when the foot-washing basin 110' is stored in the main body 200', it may get caught on the lower end 212' of the toilet basin. To avoid this, the main body 200' must either secure more space in front of it to accommodate the foot-washing basin 110', or the foot-washing basin 110' must not be fully stored in the main body 200' and must protrude.

[0071] To address this issue, it is advisable to make the entire or a portion of the inner wall of the foot-washing basin 110' a flexible material.

[0072] For example, the inner wall of the foot-washing basin 110' is divided into a central part and both ends. A variable wall body 114' that abuts against the lower end 212' of the toilet basin is located in the central part of the inner wall, while fixed wall bodies 113' that do not abut against the lower end 212' of the toilet basin are located at both ends of the inner wall.

[0073] The variable wall 114' is made of an elastically deformable rubber material. Here, the rubber material includes natural rubber and synthetic rubber, and among them, it consists of one form from silicone, urethane, and latex.

[0074] In particular, latex is a substance in which fine polymer particles are dispersed in an aqueous solution, and since it is one of the widely used substances, its applicability is even better depending on the application and environment.

[0075] As a result, the variable wall 114' can elastically deform to match the outer shape of the lower end 212' of the toilet bowl basin of the main body 200' when the foot-washing basin 110' is inserted into the main body 200' (when it is located inside the front part of the main body).

[0076] It is preferable that the fixed wall 113' is airtightly connected to both ends of the variable wall 114'.

[0077] Figures 6 to 9 schematically show an example in which the inner wall of the foot washing basin is elastically deformed in a Western-style toilet with a foot health management device according to one embodiment of the present invention.

[0078] Figures 6 to 9 are diagrams illustrating an example in which the variable wall 114' of the foot-washing tub 110' is variable due to external contact, and do not show the detailed configuration of the foot-washing tub 110' (which will be illustrated in the drawings described later).

[0079] Therefore, Figures 6 to 9 are merely diagrams illustrating that the variable wall 114' of the foot-washing tub 110' is made of an elastically deformable material, and the shape of the foot-washing tub 110' is not limited by the illustrated form.

[0080] The variable wall 114' shown in Figures 6 and 7 is made of, for example, latex rubber and is elastically deformable. At this time, the parts to which the variable wall 114' is connected are airtightly sealed so that water does not leak even when the user washes and bathes their feet using the foot washing tub 110'.

[0081] As another example, the method shown in Figures 8 and 9 will be described.

[0082] In this embodiment, the inner wall of the foot-washing tub 110' is composed of a fixed wall 113' and a variable wall 115', and connecting parts 116a' and 116b' that connect the fixed wall 113' and the variable wall 115' and seal the connection to prevent water leakage. The fixed wall 113' is molded together with the foot-washing tub 110' and has a space in the center where the variable wall 115' is located. The connecting parts 116a' and 116b' are used when the variable wall 115' and the fixed wall 113' are joined, with three sides of the variable wall 115' excluding the upper end being joined to the fixed wall 113' using the connecting parts 116a' and 116b'. Therefore, when the variable wall 115' and the fixed wall 113' are joined using the connecting parts 116a' and 116b', a rectangular wall is maintained in plan view.

[0083] However, when the foot-washing basin 110' is located in the storage area of ​​the main body (200' in Figure 5), the variable wall 115' rotates or is pushed inward into the foot-washing basin 110' along the shape of the lower end 212' of the toilet basin of the main body, so the connecting parts 116a' and 116b' must be able to deform to reflect this.

[0084] Therefore, suitable materials for the connecting parts 116a' and 116b' are synthetic rubber such as latex, where the part 116a' connecting the left and right sides of the variable wall 115' is elastically deformable, and the part 116b' connecting the lower part of the variable wall 115' is foldable.

[0085] As an example of a modified form, the connecting portion 116' can be configured to have a wrinkled shape in order to increase the degree of deformation. When a wrinkled connecting portion 116' is adopted, the left and right sides of the connecting portions 116a' and 116b' are normally folded, as shown in Figure 9, and when the foot-washing basin is inserted into the toilet bowl, they spread out, and the variable wall 115' rotates inward into the internal space of the foot-washing basin and tilts.

[0086] On the other hand, the variable walls 114' and 115' in Figures 6 to 9 may be configured to be raised and lowered (not shown) on a portion of the inner wall of the foot-washing tub 110'. The variable walls 114' and 115' may be automatically raised and lowered according to the position of the foot-washing tub 110', or the user may manually move them up and down using a separate switch. What is important in this case is that the variable walls 114' and 115' have a sealed structure so that water does not leak to the outside when the user washes or bathes their feet using the foot-washing tub 110'.

[0087] In short, the variable walls 114' and 115' must be adjusted so that their height is lower when the foot-washing basin 110' is inserted into the lower front part of the Western-style toilet (Figure 4, 10), and the position of the variable walls 114' and 115' must be adjusted so that their height is higher when the user slides forward from the Western-style toilet (Figure 4, 10) to use the foot health management device (Figure 4, 100).

[0088] Figure 10 is a schematic cross-sectional view showing the wastewater discharge section of a foot health management device according to one embodiment of the present invention.

[0089] The wastewater discharge section 150 shown in Figure 10 includes a wastewater inlet pipe 151, an odor blocking section 152, and a wastewater discharge pipe 153.

[0090] The wastewater inlet pipe (151; the horizontal pipe at the front end of the U-shaped pipe) is connected to the wastewater outlet of the foot-washing tank (110 in Figure 2 and 110' in Figure 3) and passes through a connecting hole (not shown) in the main body (200 in Figures 1 and 2, and 200' in Figure 3). Here, the connecting hole is a hole through which the wastewater inlet pipe 151 can pass. Such a connecting hole is formed in the section where the wastewater discharge section 150 is connected to the main body (200 in Figures 1 and 2, and 200' in Figure 3).

[0091] The odor-blocking section (152; U-shaped pipe) is positioned between the sewage inlet pipe 151 and the sewage outlet pipe 153 to block odors flowing in from the sewage outlet on the toilet floor. For this purpose, the odor-blocking section 152 is best implemented using a U-shaped pipe or a dedicated valve to block malodorous odors flowing in from the sewage outlet on the toilet floor.

[0092] The wastewater discharge pipe (153; the vertical pipe at the rear end of the U-shaped pipe) has its front end connected to the odor-blocking section 152 and its rear end connected to the wastewater outlet on the toilet floor.

[0093] Here, the wastewater discharge section 150 can be formed as an assembly consisting of a wastewater inlet pipe 151, an odor blocking section 152, and a wastewater discharge pipe 153, or these components may be combined and integrally molded with the wastewater piping 201 of the main body 200.

[0094] Alternatively, the wastewater discharge section 150 may be incorporated into a flange (not shown) used when connecting the wastewater piping of a Western-style toilet (10 in Figures 1-3) to the wastewater outlet on the toilet floor. For example, the wastewater discharge section 150 can be incorporated into an eccentric flange so that the eccentric flange can be deformed to discharge wastewater from the foot-washing basin (110 in Figure 2 and 110' in Figure 3).

[0095] The foot health management device (100 in Figures 1 and 2, and 100' in Figure 3) periodically discharges clean water to fill the odor-blocking section 152. This is to prevent sewage from accumulating in the U-shaped odor-blocking section 152. It is best to maintain an airtight seal around the odor-blocking section 152.

[0096] Figures 11 and 12 are schematic cross-sectional diagrams illustrating an example of the operation of a foot health management device according to one embodiment of the present invention, viewed from the front and rear.

[0097] Referring to Figures 11 and 12 in parallel, the foot-washing tub 110 has a structure that accommodates the user's feet inside, and the bottom plate is equipped with a washing plate 111 on which the user's feet rest.

[0098] The cleaning plate 111 is basically a flat surface, but it can be deformed to include a central part (where the arch of the foot is located) that protrudes upward.

[0099] The cleaning plate 111 has multiple projections 111a that protrude upward, arranged at intervals.

[0100] The projection 111a effectively assists in washing the soles of the feet and plays a role in maintaining a certain distance between the foot and the bottom or a nozzle formed on the bottom (upward spray nozzle: 124). Preferably, the projection 111a has a shape that provides a rough texture when it comes into contact with the sole of the foot, providing a pressure point massage effect, while also allowing the foot to be rubbed and washed.

[0101] On the other hand, the projection 111a may act as a frame that elastically deforms where the foot is placed, or recesses downwards to take the shape of the foot, so that the foot can be stably placed on the washing plate 111.

[0102] The washing plate 111 has a structure that allows it to be detached from the foot-washing tub 110 and can be configured to be replaceable. Alternatively, it may be a part or all of the bottom surface of the foot-washing tub 110, with protrusions formed on the bottom surface where feet are placed.

[0103] The foot-washing tub cover 112 covers a portion of the upper surface (front portion) of the foot-washing tub 110 to prevent water from splashing out and provides an area where the downward-facing spray nozzle 122, described later, is installed.

[0104] The foot-washing basin cover 112 is detachable from the foot-washing basin 110, and may be rotatable with a hinge shaft (not shown) connected to one side of the front end of the foot-washing basin 110.

[0105] The spray unit 120 sprays cleaning water into the inner space of the foot-washing tub 110. The cleaning water is basically water, but it can contain cleaning solution.

[0106] The spray unit 120 includes a side spray nozzle 123 and an upward spray nozzle 124, and may selectively include a downward spray nozzle 122 formed on the bottom surface of the foot wash tub cover 112.

[0107] One or more side spray nozzles 123 are positioned on the inner circumferential surface of the foot washing tub 110 and spray water to the sides. These side spray nozzles 123 spray water from a position on the inner wall of the foot washing tub 110 in a position lower than horizontal.

[0108] Since the washing water is sprayed from the inside left and right of the foot-washing basin 110, you can twist your ankles and wash the soles of your feet.

[0109] On the other hand, the front end of the bottom of the foot-washing tub 110 can be formed higher than the height of the rear end, and the position of the side spray nozzles 123 facing the toes can be set higher. In this case, the direction of the sprayed washing water becomes closer to vertical, making it possible to wash the top of the foot and toes more effectively.

[0110] The upward-facing spray nozzles 124 are positioned at intervals on the bottom surface of the washing plate 111 and spray water upward to wash the soles of the feet.

[0111] At this time, it is preferable that the spray pressure of the upward spray nozzle 124 is configured so that the height of the sprayed cleaning water is maintained within the height of the foot-washing tub 110, in order to prevent the cleaning water from splashing outside the foot-washing tub 110. Alternatively, the spray pressure of the upward spray nozzle 124 can be increased when washing the soles of the feet, and the spray pressure can be immediately reduced when it is detected that the feet have been lifted from the washing plate.

[0112] One or more downward-facing spray nozzles 122 are positioned inside the cover (112 in Figure 3) to spray cleaning water downwards. When additional downward-facing spray nozzles 122 are provided, they are effective for cleaning the tops of the feet and toes.

[0113] The spray unit 120 is connected to another externally located cleaning water supply unit (160 in Figure 15) and / or cleaning liquid supply unit (not shown). Cleaning water is supplied through an external water supply pipe, but a water tank (not shown) for storing cleaning water can be provided inside the foot washing tank 110 to adjust the spray pressure. For example, if the water pressure in the water supply pipe is excessively high, the water tank acts as a buffer to maintain the appropriate spray pressure, and if the spray pressure of the cleaning water needs to be higher than the water pressure in the water supply pipe, a piston (not shown) connected to the water tank operates to increase the spray pressure.

[0114] The cleaning fluid supply unit is supplied with cleaning fluid from an external cleaning fluid supply device (not shown) or consists of a cartridge replacement type. The cleaning fluid supply unit is connected to the cleaning fluid nozzle 125. In another embodiment, the cleaning fluid supply unit is connected to all the nozzles of the spray unit 120, so that each nozzle of the spray unit 120 sprays cleaning fluid alternately with cleaning water, or sprays cleaning fluid mixed with cleaning water.

[0115] In other words, the downward spray nozzle 122, the side spray nozzle 123, the upward spray nozzle 124, and the cleaning fluid nozzle 125 are connected to a single pipe, and each branched section is equipped with a spray valve (not shown) to selectively spray cleaning water and / or cleaning fluid. Alternatively, for structural convenience, only the downward spray nozzle 122 and the cleaning fluid nozzle 125 may be connected to a single pipe, with a spray valve positioned between them to selectively spray cleaning water and / or cleaning fluid.

[0116] The operation of the injection unit 120 is controlled by the control unit (140 in Figure 3) based on user input from the user input unit (130 in Figure 3) or by a predetermined control logic.

[0117] At this time, in order to prevent water from splashing outside the foot-washing tub 110, it is preferable that the spray unit 120 sprays water when the foot-washing tub 110 is filled with a predetermined fixed amount of water. Here, the predetermined fixed amount can be measured by the user at the height to which the foot-washing tub 110 is filled with washing water, and this setting can be changed according to the environment.

[0118] The spray pressure, spray pattern, and spray angle of the cleaning water and / or cleaning liquid sprayed by the spray unit 120 can be combined or controlled in various ways, as will be described later. The spray unit 120 is electrically connected to the user input unit (130 in Figures 2 and 3) and an LED (not shown) indicates whether the power is on (ON) or off (OFF).

[0119] Figure 13 is a schematic diagram showing an example of the operation of the heel washing section in a Western-style toilet with a foot health management device according to one embodiment of the present invention.

[0120] Referring to Figure 13, the foot health management device according to the present invention (100 in Figures 1 to 12) may further include a heel washing section 180.

[0121] The heel cleaning unit 180 is rotatably mounted at the rear end of the foot health management device 100 (the part where the heel is located) to allow the heel to be washed more thoroughly and to remove calluses from the heel. This heel cleaning unit 180 is positioned to have a predetermined incline that conforms to the shape of the heel.

[0122] The heel cleaning unit 180 includes a rotating member 181, a brush 182, and a drive unit 183.

[0123] The rotating member 181 has a structure that allows it to rotate by being connected to the inner rear end of the foot-washing tub (110 in Figures 1 to 12) in the width direction or in the longitudinal direction. Such a rotating member 181 has rotating pins 181a at both ends in the longitudinal direction.

[0124] The brush 182 is the part that directly contacts the space between the user's toes and has a structure that surrounds the rotating member 181. The outer surface of the brush 182 is rough, allowing it to effectively remove contaminants (such as dead skin cells) between the toes. For ease of cleaning, it is preferable that the brush 182 be detachable from the rotating member 181.

[0125] When a command signal is transmitted to the control unit 140 by the user operating the user input unit 130, the drive unit 183 can rotate the rotating member 181 by the control unit 140. Figure 14 is a schematic diagram showing a modified operation of the heel washing section in a Western-style toilet with a foot health management device according to one embodiment of the present invention.

[0126] Referring to Figure 14, the heel cleaning section 180 can be arranged to be inclined at a predetermined angle along the shape of the heel, and can be composed of three parts that surround the heel.

[0127] At this time, the heel cleaning unit 180 can be adjusted horizontally and vertically via the position adjustment unit 184. The drive mechanism for the drive unit 183, user input unit 130, and control unit 140 is the same as that shown in Figure 13 above, so it is omitted here.

[0128] On the other hand, another example of the configuration of the heel cleaning unit 180 is that one rotating shaft moves laterally in a direction perpendicular to the direction in which the rotating shaft is positioned while cleaning the heel and / or toe.

[0129] Since the heel washing section 180 and the washing plate (111 in Figures 11 and 12) are both located near the bottom of the foot washing tub (110 in Figures 1 to 12), it is preferable to reduce the size of the washing plate 111 and install the heel washing section 180 in the remaining space, separated from the washing plate 111 by a predetermined distance, in order to reduce or eliminate mutual mechanical interference.

[0130] In another embodiment, in addition to the heel cleaning section 180, a toe cleaning section (not shown) can be further provided at the front end of the foot health management device (100 in Figures 1 to 12). The toe cleaning section has the function of cleaning and massaging the toes, which correspond to the part between the arch of the foot and the toes, and its specific structure is substantially the same as that of the heel cleaning section described above.

[0131] Additionally, the foot health management device 100 according to the present invention may be equipped with a heating unit (not shown) for heating the washing water. The heating unit heats the washing water before spraying using a method such as a water heater or electric heater so that warm washing water is sprayed.

[0132] Figure 15 is a schematic diagram showing a toe-spray nozzle in a Western-style toilet with a foot health management device according to one embodiment of the present invention.

[0133] Referring to Figure 15, the foot health management device is further equipped with toe spray nozzles 171.

[0134] The toe spray nozzles 171 are positioned at intervals in the width direction of the washing plate (111 in Figures 11 and 12) so as to be located between the toes that are placed longitudinally on the washing plate, and spray water between the toes.

[0135] The toe spray nozzle 171 is located between the toes and is configured such that its width can be adjusted laterally or its length can be adjusted vertically, based on the toes shown in Figure 15.

[0136] The toe spray nozzle 171 is cylindrical and has multiple spray holes 171a on its outer surface. The toe spray nozzle 171 is connected to the cleaning water supply unit 160 and has the function of spraying cleaning water to the outside. The cleaning water supplied from the cleaning water supply unit 160 is sprayed to the outside (between the user's toes) through the multiple spray holes 171a.

[0137] As shown in the figure, the toe spray nozzle 171 has a columnar shape, but the toe spray nozzle 171 may also have a tapered shape at a part of its upper end, where the width increases from the top to the bottom, making it easy to insert the toes.

[0138] The toe spray nozzle 171 may be adjustable vertically and may have a structure that allows it to spray water while rotating.

[0139] Since the shape and size of the toes differ for each person using the foot health management device 100 according to the present invention, the toe spray nozzle 171 can be moved by a predetermined length (installation interval) in the width (and / or length) direction of the washing plate 111 to conform to the shape of the user's toes, so that it can be applied to an unspecified number of people.

[0140] The position of the toe spray nozzle 171 for each user is stored in a memory device (not shown), and can be configured to move to the stored position for each user with a simple operation of the user input unit (130 in Figures 2 and 3). For example, if two people, A and B, who have different toe sizes and shapes, use the foot health management device 100, A can operate the user input unit (for example, by pressing button number 1), and the toe spray nozzle 171 will automatically move to a position that suits A's toes, and B can operate the user input unit (for example, by pressing button number 2), and the toe spray nozzle 171 will automatically move to a position that suits B's toes.

[0141] The operation and control of the foot health management device (100 in Figures 1 to 12) according to the present invention will be described below. The operation of the various electrical / electronic devices of the foot health management device 100 according to the present invention, including the aforementioned spray unit 120, cleaning fluid nozzle 125, and user input unit (130 in Figures 2 and 3), is controlled by a control unit (not shown).

[0142] First, we will specifically explain the control of injection pressure and injection operation.

[0143] The foot health management device 100 according to the present invention can be controlled so that each spray nozzle sprays sequentially in order to maintain the spray pressure of each spray nozzle above a certain level. For example, the upward spray nozzle 124 - side spray nozzle 123 - toe spray nozzle 171 are operated in that order to maintain a spray pressure above a certain level. If necessary, a pressurizing pump (not shown) may be used to increase the spray pressure, and it goes without saying that if it is possible to maintain an appropriate spray pressure, the device may be controlled to spray from two or more nozzles simultaneously.

[0144] On the other hand, to enhance the cleaning and massage effects, each nozzle can be controlled to spray with a time-varying spray pressure.

[0145] A variety of combinations are possible for the spraying methods of the cleaning water and cleaning solution. For example, when the spraying unit 120 sprays cleaning water, the system may be configured so that water and cleaning solution are sprayed alternately from the same nozzle or in a predetermined spray pattern, or cleaning water mixed with water and cleaning solution may be sprayed, or only water may be sprayed. Alternatively, the cleaning solution may be controlled to be sprayed only from a dedicated nozzle (cleaning solution nozzle; 125).

[0146] To enhance the cleaning and massage effects, each nozzle of the spray unit 120 is adjustable in spray angle to the left / right or up / down, and it is preferable that the spray angles of the side spray nozzles 123 and upward spray nozzles 124 are limited to a predetermined range so that water does not splash outside the foot washing tub 110.

[0147] The injection pressure, injection method, and injection angle are controlled by the control unit (140 in Figures 2 and 3) via user operation via the user input unit (130 in Figures 2 and 3) or by a preset control logic.

[0148] Figure 16 is a schematic diagram showing an example of the operation of the toe washing section in a Western-style toilet with a foot health management device according to one embodiment of the present invention.

[0149] Referring to Figure 16, the toe washing unit 170 includes a toe spray nozzle 171, a washing member 172, and a rotating piece 173.

[0150] A cleaning member 172 is rotatably mounted on the upper part of the toe spray nozzle 171. The cleaning member 172 has a cylindrical shape with an open bottom. The rotating piece 173 is located at the upper end of the cleaning member 172 and is capable of coaxial rotation with the cleaning member 172.

[0151] The toe cleaning unit 170 has a cleaning member 172 connected to a rotating piece 173 that rotates axially, covering a portion of the upper end of the toe spray nozzle 171, and cleaning between the toes. In other words, the cleaning member 172 has a structure that rotates in conjunction with the rotating piece 173 when the rotating piece 173 is rotated by the cleaning water sprayed from the spray unit 120.

[0152] The cleaning member 172 is the part that comes into direct contact with the skin in order to remove foreign matter, including various types of dead skin cells, between the toes. Therefore, it is made of a hard sponge, either a rubber type made by foaming raw natural rubber or a urethane type made of synthetic resin. The outer surface of such a cleaning member 172 may have multiple protrusions formed at intervals.

[0153] Here, a bearing (not shown) may be provided between the inner circumferential surface of the cleaning member 172 and the outer circumferential surface of the toe spray nozzle 171 to assist in the rotation of the cleaning member 172. Figures 17 to 20 schematically show modified operation of the toe washing section in a Western-style toilet with a foot health management device according to one embodiment of the present invention.

[0154] The cleaning member 172' shown in Figures 17 to 20 has a cylindrical shape with an open bottom and can rotate axially while surrounding the outside of the toe spray nozzle 171'. However, the cleaning member 172' in Figures 17 to 20 has a different rotation method than the embodiment described above.

[0155] Before explaining this rotation method, we will describe the structure of the toe spray nozzle 171' and the cleaning member 172'.

[0156] As shown in Figure 18, the toe spray nozzle 171' has a structure that allows it to rotate with the cleaning member 172' inserted.

[0157] For this purpose, the toe spray nozzle 171' has a cleaning water guide groove 171b', a spray port 171a', and a rotating shaft 171c'. The cleaning water guide groove 171b' is formed as a recess at intervals along the longitudinal direction on the outer circumferential surface of the toe spray nozzle 171'. The spray port 171a' is formed to penetrate the cleaning water guide groove 171b' at intervals. The rotating shaft 171c' is connected to a rotating shaft connecting groove 172b' formed on the inner surface of the cleaning member 172'.

[0158] The cleaning member 172' has a plurality of spray ports 172a' that communicate with the spray ports 171a' of the toe spray nozzle 171'.

[0159] Figure 19(a) shows the A-A' cross-section of Figure 17, and (b) shows an example in which the cleaning member cover 174' is added to (a). Referring to Figures 19(a) and (b), the spray nozzle 172a' has a structure that penetrates diagonally with respect to the axis of the cleaning member 172'.

[0160] The spray nozzle 172a' of the cleaning member 172' has a structure that connects to the cleaning water guide groove 171b' of the toe spray nozzle 171'.

[0161] Here, the cleaning water guide groove 171b' is a space through which water flows, and has the function of continuously and uninterruptedly spraying the cleaning water that flows into the cleaning member 172' via the toe spray nozzle 171' to the outside.

[0162] As shown in Figure 20, when the cleaning water supplied from the cleaning water supply unit 160 is sprayed through the nozzle 171a' of the toe spray nozzle 171' to the nozzle 172a', the nozzle 172a' induces the rotation of the cleaning member 172' by the spray pressure.

[0163] Since the cleaning member 172' rotates due to the force of the cleaning water being ejected through the nozzle 172a', if it is made of a soft material, it may not rotate between the user's toes. Therefore, the cleaning member 172' is made of a hard material within a range that allows it to rotate, and multiple protrusions are formed on its outer surface to assist in cleaning.

[0164] The cleaning member cover 174' is replaceable by being sandwiched between the outer surfaces of the cleaning member 172'. That is, the cleaning member cover 174' is a replaceable type for maintaining cleanliness because the contact surface may become contaminated when removing contaminants between the user's toes. In this case, it is preferable that the cover hole 174a' of the cleaning member cover 174' communicates with the spray nozzle 172a'.

[0165] The toe cleaning section 170' has toe cleaning nozzles 171' that extend vertically upward and are positioned one or more between each of the user's toes, which clean and massage the spaces between the toes by rotating.

[0166] It is preferable to increase the cleaning power and massage effect by placing one or more protrusions on the outer surface of the cleaning member 172' surrounding the toe cleaning nozzle 171', and it is preferable that the body of the cleaning member 172' itself is hard, but the protrusions are soft.

[0167] The following describes an embodiment of the automatic cleaning operation of the foot health management device 100 according to the present invention.

[0168] The automatic cleaning function consists of a foot placement detection step, a cleaning fluid spraying step, and a foot washing step. The foot placement detection step is a step that detects when a foot is placed on the cleaning plate 111. The cleaning fluid spraying step is a step in which the control unit receives foot position information values ​​detected by a foot detection sensor (not shown) and drives the cleaning fluid nozzle 125 of the spraying unit 120 to spray the cleaning fluid. The foot washing step is a step in which, after the cleaning fluid has been sprayed and a first waiting time has elapsed, water is sprayed from the water spraying nozzle to wash the feet.

[0169] The system may optionally include a foot-detachment detection step in which a foot detection sensor detects that a foot has left the washing plate 111, and an internal cleaning step in which, after a second waiting time has elapsed, cleaning water is sprayed from the spray unit 120 to clean the internal space of the foot-washing water tank 110.

[0170] Here, the first and second waiting times refer to the times predetermined for the process, and these times can be changed by the user.

[0171] The user can make various presets using the user input unit (130 in Figures 2 and 3). Basic values ​​such as the spray pressure of the spray unit 120, the first and second waiting times for the automatic cleaning function, and the amount of cleaning fluid sprayed can be set.

[0172] The foot placement detection step is performed by a foot detection sensor.

[0173] The foot detection sensor can be implemented by providing a light-receiving unit (not shown) and a light-emitting unit (not shown) on the left and right inner walls of the foot-washing tub 110, or by providing a pressure sensor at the bottom of the washing plate 111.

[0174] Such a foot detection sensor transmits information values ​​to the control unit when it detects the position of the foot when it is close to the washing plate 111 or the pressure value at which the foot is placed. The control unit is electrically connected to the foot detection sensor and compares the information values ​​transmitted from the foot detection sensor with a preset reference value. If the resulting value matches the reference value, it drives and controls the spray unit 120.

[0175] In the foot washing step, the control unit controls the spray unit 120 so that the inner containment space of the foot washing tank 110 is automatically washed for a preset time. Here, the preset time is calculated based on statistical values ​​accumulated from various data, and the initial setting value may differ depending on the function, and the setting value may be determined by the user. To enhance the effectiveness of foot washing, the spray method, spray pressure, and spray angle of the washing water and washing solution are automatically varied by user input or by a preset logic.

[0176] The internal cleaning step is performed when the user removes their feet after washing their feet. When the control unit detects that the feet have left the cleaning plate 111, the spray unit 120 is stopped from driving, and the control unit controls the spray unit 120 to clean the inside of the foot washing tank 110 using the automatic cleaning function.

[0177] For internal cleaning of the foot health management device 100, the control unit adjusts the spray angle and sprays cleaning water towards the cleaning plate 111 for a preset time. The set time can be changed by the user. Alternatively, a contamination sensor (not shown) can be used to detect the degree of cleaning of the cleaning plate, and the cleaning time of the cleaning plate can be changed until it reaches an appropriate level of cleaning.

[0178] The cleaning water sprayed during the internal cleaning step may be a mixture of cleaning solutions having stronger cleaning power than the cleaning water used for foot washing. For this reason, the cleaning solution storage unit is configured to store the cleaning solution for cleaning the cleaning board separately from the cleaning solution for foot washing.

[0179] The configuration of the present invention has been described above with reference to several preferred embodiments. The present invention has a structure that allows the soles of the feet and the spaces between the toes to be thoroughly washed without bending the waist or using the hands, making it easy for people with physical disabilities or limited mobility to wash their feet.

[0180] Furthermore, the foot health management device can solve the problems of conventional management by incorporating a function that automatically cleans the device after foot washing and foot bathing. At this time, the foot health management device, after the user's feet have been washed and bathed, may be equipped with an ultraviolet lamp (not shown) or a drying device (not shown) inside the cover of the body to eliminate bacteria and remove moisture.

[0181] It goes without saying that the present invention is not limited to the embodiments described above, but can be implemented in various ways within the permissible range of the technical concept of the present invention. [Industrial applicability]

[0182] As described above, the embodiments of the present invention can not only function as a toilet in a confined space, but also provide foot washing and massage while seated on the toilet.
